BACKGROUNDThis invention relates to paintball loader systems. More particularly, it relates to providing paintball loader systems to efficiently deliver paintballs to a paintball gun (also known as paintball markers).
The game of paintball involves participants utilizing paintball guns that discharge frangible paint-filled balls “fired” from the gun that burst upon impact to leave a mark at the point of impact. Paintball guns use a pneumatic system for firing the paintballs, typically using compressed air or other compressed gas. Electronically controlled guns are generally capable of very high rates of fire, so much so that the limiting factor in firing speed is typically the rate at which “paint” can be loaded into the gun. In professional competitions, the rate of fire can be as much as 15 balls per second. Often a player will experience missed shots or skipped shots due to a hopper not keeping up with the operation of the gun.
A significant problem with high-speed loading of paintballs is the controlled application of forces on the paintball. High loading velocities are generally associated with the application of high levels of force to the paintballs. The inherent fragility of the paintballs limits the maximum level of force that can be concentrated on the surface of the ball without breakage.
An additional problem related to high-speed loading of paintballs is the need for consistent feeding of paintballs into the gun, without interference or interruption. Occasionally, a paintball will break within the hopper hindering the operation. Typically, paint-related debris must be cleared from the hopper before the hopper can be returned to full service. The closed construction of conventional hoppers makes cleaning both difficult and time-consuming. A system to overcome the above-described problems would be of great benefit in advancing the paintball sports.

Feedneck 112 preferably comprises a hollow tubular channel having an interior diameter of slightly greater size than the outer diameter of paintballs 106, as shown. The larger diameter of feedneck 112 provides sufficient clearance for the passage of airflow around paintballs 106 while reducing the effects of blowback from the paintball gun 104. Feedneck 112 preferably comprises a directional transition between a generally horizontal inlet from paintball storage compartment 110 to a generally vertical outlet extension structured and arranged to firmly engage the female feedneck receiver 128 of paintball gun 104, as best shown in
A specialized power-driven conveyor assembly 114 is preferably used to mechanically convey paintballs 106 from paintball storage compartment 110 to feedneck 112 (at least embodying herein at least one passage structured and arranged to pass the paintballs between such at least one paintball storage compartment and the at least one breach inlet), as shown. Preferably, conveyor assembly 114 occupies the lower portion of paintball storage compartment 110 to allow gravity-assisted movement of the plurality of paintballs 106 toward the conveyance mechanism, as shown.
Conveyor assembly 114 preferably comprises at least one rotating auger 116 positioned within the lower portion of paintball storage compartment 110, as shown. Preferably, auger 116 is rotatably mounted on auger shaft 118 that is preferably aligned coaxially along longitudinal axis of rotation 120, as shown. Preferably, auger 116 comprises helical flighting 122 spiral wound about longitudinal axis of rotation 120, as shown.

These concave interstitial spaces preferably comprise about a 0.75-inch radius and function to contact a relatively large portion of the outer surface of paintballs 106, as shown. This preferred arrangement allows auger 116 to engage the paintballs in a manner that allows for improved distributed transfer of conveyance forces. Since the total force applied to the surface of the ball is spread over a wide area, the level of concentrated point loading at the surface of the ball is decreased. This allows the application of greater overall levels of pressure force while decreasing the risk of ball breakage.
In addition, auger 116 acts as a force distributor, allowing the moving force to be distributed to individual paintballs 106 queued within the ball “stack”, rather than applying a single point load on the initial ball of the “stack”. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as intended use, advances in technology, etc., other force transfer arrangements, such as, rotating wheels, belts, cups, etc., may suffice.
Preferably, auger 116 is operationally coupled to a mechanical power source identified herein as power assembly 124, as shown. Preferably, power assembly 124 is structured and arranged to produce mechanical power, most preferably a rotational torque usable to operate conveyor assembly 114. In most preferred embodiments, power assembly 124 utilizes an electrically driven motor 150 to produce such mechanical power. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as user preference, intended use, etc., other torque generation arrangements, such as springs, pneumatic drives, etc., may suffice. Preferably, power coupler 126 is positioned between power assembly 124 and auger 116 and preferably functions to transfer the rotational force generated by power assembly 124 to auger 116, as shown. Preferably, rotation of auger 116 moves the paintballs 106 engaged within auger 116 in an axial direction generally toward transverse guide wall assembly 144 (the forward wall containing the opening to feedneck 112), as shown. The above arrangement at least embodies herein wherein such at least one force conveys the at least one paintball generally toward such at least one ball passage along at least one axial direction of such at least one rotatable auger.
The preferred outer shape of paintball storage compartment 110 is generally aerodynamic in character, as shown, being more slender in the front, to increase the chance of safely deflecting incoming paintball away from the system.
Preferably, upper housing portion 130 comprises a generally circular access opening 136 used to refill paintball storage compartment 110, as shown. Preferably, a pivoting door cover 138 covers access opening 136 to prevent loss of paintballs during operation. Door pivot assembly 140 preferably comprises a pivot shaft and tension spring 141 used to bias door cover to an open position. Preferably, door cover 138 comprises door retainer assembly 142 designed to secure door cover 138 in a closed position. Preferably, door retainer assembly 142 comprises at least one magnet, mounted within door cover 138, interoperating with at least one magnetic element located within upper housing portion 130, as shown.
For efficiency of fabrication, transverse guide wall assembly 144 is preferably constructed as a separate insert that is permanently bonded to main housing portion 130 during assembly (see
Preferably, removable back housing 134 is slidably engaged within a lower rear opening of main housing portion 132, as shown. This preferred tray-like feature allows (as shown) the entire conveyor assembly 114 to be removed from the main storage compartment for inspection and service (at least embodying herein at least one removable tray assembly structured and arranged to be removable from at least one paintball storage compartment). Preferably, removable back housing 134 and lower rear opening of main housing portion 132 each comprise a set of complementary interlocking alignment rails 162 (as shown) to assist in accurately positioning removable back housing 134 within main housing portion 132 during insertion. Preferably, removable back housing 134 comprises user interface accommodation 164, providing access to user interface board 166 (located within the rear of conveyor assembly 114), as shown.
A preferred feature of paintball loader system 100 is the ability of conveyor assembly 114 to selectively manipulate paintballs within paintball storage compartment 110 to provide improved loading consistency, regardless of the quantities of paintballs that are stored within the compartment.
Preferably, conveyor assembly 114 is designed to perform a first selection process wherein paintballs 106, favorably positioned for loading, are conveyed by auger 116 to opening 198 at feedneck 112. In a second preferred selection process, conveyor assembly 114 is preferably designed to eject paintballs 106 unfavorably positioned for delivery to feed neck 112 from conveyor assembly 114. Both
As previously described, first guide-wall 168 and second guide-wall 170 together define ball channel 172, preferably located generally below auger 116, as best illustrated in
Preferably, auger 116 comprises proximal auger end-region 200 and distal auger end-region 202, as shown. Preferably, proximal auger end-region 200 is positioned generally adjacent power coupler 126, with distal auger end-region 202 positioned generally adjacent opening 198, as shown.
Preferably, paintballs 106 contacting first guide-wall 168 are guided by first guide ramp 203 (and by the sloping surfaces of first guide-wall 168) to positions of engagement within the concave interstitial spaces of helical flighting 122 (to the first guide-wall-side of longitudinal axis of rotation 120), as shown. These paintballs are favorably positioned for delivery to feed neck 112, as shown. Preferably, first guide ramp functions to control the angle and point of ball entry and preferably guides paintballs 106 located adjacent transverse guide wall assembly 144 to positions of engagement within the concave interstitial spaces of the first guide-wall-side of helical flighting 122, generally near proximal auger end-region. Preferably, first guide ramp 203 slopes downwardly from a high elevation generally adjacent distal auger end-region 202 to a low elevation terminating near about the midpoint of ball channel 172, as shown.
Preferably, paintballs 106 contacting second guide-wall 170 are guided by second guide ramp 206 (along with the sloping surfaces of second guide-wall 170) to positions of engagement within the concave interstitial spaces of the second guide-wall-side of helical flighting 122 (that is, the second guide-wall-side of longitudinal axis of rotation 120), as shown. If paintballs 106 have previously deposited within ball channel 172, and paintballs 106 are queued in distal channel area 208, paintballs 106 engaged within helical fighting 122 on the second guide-wall-side of longitudinal axis of rotation 120 are unfavorably positioned for delivery and are ejected from auger 116 (it should be noted that paintballs 106 engaged on the second guide-wall-side of longitudinal axis of rotation 120 drop to distal channel area 208 and are preferably conveyed to feedneck 112 when no paintballs 106 reside within the distal portion of ball channel 172).
Ejection of paintballs from auger 116 is preferably assisted by the contact interaction of paintballs 106 with ejection ramp 204, as shown. Preferably, ejection ramp 204 is integrally formed within the distal end of second guide-wall 170, as shown. Preferably, ejection ramp 204 is designed to lift paintballs 106 out of helical fighting 122 (to the right of longitudinal axis of rotation 120), as shown. The preferred upward slope of ejection ramp 204 (rising toward the forward transverse guide wall assembly 144) lifts paintballs 106 from auger 116 as they are driven toward transverse guide wall assembly 144, as shown. As the paintballs 106 collide with transverse guide wall assembly 144, they are ejected from auger 116 and are preferably relocated by transverse guide wall assembly 144 (assisted by the counter-clockwise rotation of auger 116) toward the first guide-wall-side of longitudinal axis of rotation 120, as best shown in
Once relocated, paintballs 106 previously ejected from auger 116 reside in an area of paintball storage compartment 110 generally favorable to the delivery of the relocated paintballs 106 to feedneck 112. More specifically, a significant portion of the relocated paintballs 106 will preferably reside in a favorable loading position adjacent first guide ramp 203 and are eventually guided by the wall structures to a favorable engagement within auger 116, as described above. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as intended use, size of paintball, length of auger, etc., other loading arrangements, such as the use of additional ramps, ramps of alternate shapes, positions, etc., may suffice.
It is important to coordinate the operation conveyor assembly 114 with the operation of paintball gun 104. When the user of paintball gun 104 ceases firing, the bolt of paintball gun 104 is closed, preventing paintballs from entering breach 108. When paintball gun 104 is in such an idle condition, is preferable to quickly reduce the amount of moving force applied to the ball stack. This quick reduction in the applied force prevents the sudden buildup of force levels that could break one or more paintballs within the stack. Paintball loader 102 efficiently satisfies this essential requirement by incorporating a disengager assembly 220 within power coupler 126.
Preferably, auger 116 is free to move axially along auger shaft 118 (coaxial with longitudinal axis of rotation 120) between at least one first position 222 (illustrated in

Preferably, lash cage 180 comprises a complementary distribution of longitudinal receiving slots 238 in which projecting tabs 236 engage, as shown. Preferably, receiving slots 238 are structured to allow axial movement of projecting tabs 236 (and the underlying end flange 230) relative to lash cage 180 (at least embodying herein wherein such at least one interlocker comprises at least one axial mover structured and arranged to allow axial movement of such at least one end flange relative to such at least one lash cage), as shown. Preferably, the engagement of projecting tabs 236 within longitudinal receiving slots 238 functions as a rotational coupler, coupling end flange 230 to lash cage 180, as shown (at least embodying herein wherein such at least one interlocker further comprises at least one rotational coupler structured and arranged to rotatably couple such at least one lash cage with such at least one end flange).
Preferably, each longitudinal receiving slot 238 comprises at least one longitudinal slot-length A at least greater than at least one longitudinal tab-thickness B of the engaged projecting tab 236, as shown. Furthermore, each longitudinal receiving slot 238 comprises at least one transverse slot-width substantially equal to at least one transverse tab-width of an engaged projecting tab 236. This preferred relationship enables axial movement of auger 116 relative to lash cage 180, but restricts relative radial movement between the two elements, as shown.
Preferably, auger 116 is positionally biased toward first position 222 by bias spring 188, as shown (at least embodying herein wherein such at least one power disengager comprises at least one positional biaser structured and arranged to bias such at least one auger toward such at least one first position). Preferably, bias spring 188, most preferably at least one helical spring, is situate coaxially with longitudinal axis of rotation 120, generally between end flange 230 and the rear wall of lash cage 180, as shown.

For high levels of loading performance, it is preferred to maintain a level of force on the queued stack of paintballs 106 at all times. Preferably, this application of force should be applied continuously, even while the user is not firing.
Preferably, bias spring 188 also functions to maintain continuous pressure on the ball stack, even when auger 116 is not spinning. This constant pressure assures that a paintball 106 is driven into breech 108 the moment the bolt of paintball gun 104 is opened sufficiently to pass the ball, even before electrically driven motor 150 is activated. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as intended use, cost, etc., other force generation arrangements, such as motor tensioning with variable torque controls, stepper motors with electronic controls, etc., may suffice.

Preferably, elastomeric battery door seal 345 protects the battery compartment against infiltration of moisture and functions to support the lower electrical contacts for batteries 147. In addition, elastomeric battery door seal 345 partially surrounds and protects one-piece outer feed neck 332 against impact damage by dampening impact forces imparted to the neck.
Preferably, upper shell 320 comprises a generally circular access opening 340 used to refill paintball storage compartment 310. Lid 326 preferably functions to cover access opening 340 during operation to prevent loss of paintballs and to prevent entry of debris during use.

Preferably, access opening 340 is further protected by a recessed moisture shedding channel 341 formed within upper shell 320, as shown. Preferably, the peripherally located moisture shedding channel 341 is designed to channel moisture away from access opening 340, thus extending the usefulness of the system to rainy or muddy operation. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as intended use, etc., other arrangements, such as the use of moisture resistant seals, structures designed to interface with specific speed-loading devices, etc., may suffice.

Flow data is preferably used by the system software to adjust and optimize the rotation of auger 316, as further described below.
Preferably, the sensors of both first detection unit 364 and second detection unit 366 are fully separated from the interior of feed-tube sleeve 355 by transparent feed-tube section 346. This highly preferred feature shields the sensors from paint and debris that could otherwise hinder ball-flow detection. In the event of broken paint within feed-tube sleeve 355, it is a simple matter to clear the detector “eyes” by pulling a jerk-type squeegee through feed-tube sleeve 355. This preferred cleaning process is further facilitated by the removal of auger drive tray 314 from lower shell 322, as further described in
Preferably, ball floor 350 is secured to battery compartment 344 and lower shell 322, preferably using mechanical-type fasteners 311, as shown. Preferably, alternate paintball loader 302 is assembled using a plurality of moisture-resistant seals 315, as best shown in

Preferably, paintballs 106 contacting first guide-wall 368 and second guide-wall 370 are guided to positions of engagement within the concave interstitial spaces of helical flighting 372 of auger 316. Preferably, paintballs 106 engaged within helical flighting 372 are actively conveyed toward feed-tube opening 398 of internal feed-tube sleeve 355, by the rotation of auger 316. Preferably, the distance between helical flighting 372 of auger 316 has been increased such that two paintballs 106 may be accommodated within each flight. Field testing has demonstrated that such extended auger flighting increases the rate at which auger 316 feeds paintballs 106, at all rotational speeds, when compared to a single-ball-per-flight configuration.
A preferred feature of conveyor assembly 414 is the ability to selectively manipulate paintballs within paintball storage compartment 310 to provide improved loading consistency.

As the paintballs 106 intersect with transverse guide wall assembly 444, they are either captured under projecting guide hood 374 and guided toward feed-tube opening 398, or alternatively, are ejected from auger 316. A quantity of ejected paintballs 106 are relocated by transverse guide wall assembly 444 (assisted by the rotation of auger 316) toward either first guide-wall 368 or second guide-wall 370. In alternate paintball loader 302, paintballs 106 engaging either side of auger axis of rotation 319 may comprise a favorable position allowing conveyance by auger 316 to feed-tube opening 398. Preferably, ejection of the paintballs further functions to continuously agitate the plurality of paintballs contained within paintball storage compartment 310 to further improve loading. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as intended use, size of paintball, length of auger, etc., other loading arrangements, such as the use of additional ramps, walls of alternate shapes, positions, etc., may suffice.
An issue common to most paintball players is the difficulty of cleaning a loader after use.

However, debris such as broken paintballs, dirt, gravel, etc., having a size smaller than the outer diameter of paintballs 106, preferably fall through auger opening 365 to be collected within debris tray 384. This preferred feature assists in maintaining normal operation of paintball gun 104 despite the development of debris within paintball storage compartment 110.
Preferably, auger support shaft 318 is retained within a auger drive tray 314 by a projecting tab 385 adapted to engage a circumferential slot 386 formed within the end of auger support shaft 318, as shown.

Preferably, rotator assembly 410 comprises an electrically-driven motor 358 driving a set of reduction gears 388, as shown. Preferably, operation of motor rotates support member 416, along with the projecting transfer members 415, about auger axis of rotation 319.
Preferably, end flange 430 comprises apertures 432 structured and arranged to slidably engage projecting transfer members 415, as shown in
Preferably, rotation of auger 316 exerts at least one force (at least embodying herein at least one second force) on at least one up-stream paintball of the single file alignment of paintballs 106 extending through internal feed-tube sleeve 355 to the breach of the paintball gun (see the diagram of
Preferably, auger drive assembly 408 further comprises at least one positional biaser, comprising at least one biasing force, structured and arranged to positionally bias auger 316 toward first position first position 422. Preferably, auger 316 is positionally biased toward first position 422 by bias spring 488, as shown. Preferably, bias spring 488, most preferably at least one helical spring, is situate coaxially with auger axis of rotation 319, generally between end flange 430 and the forward face of support member 416, as shown.
Again, it is highly preferred that a minimal level of force be maintained on the queued stack of paintballs 106 at all times. Preferably, this application of force should be applied continuously, even while the user is not firing. Preferably, bias spring 488 also functions to maintain continuous pressure on the ball stack, even when auger 316 is not spinning. This preferred “constant biasing force” assures that a paintball 106 is driven into the breech the moment the bolt of paintball gun 104 is opened sufficiently to pass the paintball, even before electrically-driven motor 150 is activated. The preferred design comprises a true force-feed arrangement such that when auger 316 is not rotating to provide the primary moving force (at least in body and herein at least one second force), the bias spring 488 continues to “prime” the paintball stack by maintaining a biasing force on at least one upstream paintball of the stack, thus urging the entire stack toward the breach of the gun.
The preferred use of the helical spring greatly reduces the electrical power requirements of the system, as the electrically-driven motor is not required to be the source of the biasing force. Thus, the life of the onboard batteries 146 are extended during operation.
The use of an auger to drive paintballs 106 is highly efficient in terms of weight when compared to other types of rotating systems. Furthermore, the preferred axial pre-loading arrangement of alternate paintball loader 302 is superior in that auger drive assembly 408 is substantially isolated from the action of biasing force. This greatly reduces wear on the drive components (e.g., gearing, bearing surfaces, motor shafts, etc.), that would otherwise occur if such a biasing arrangement were to be directly integrated within the motorized drive train. In addition, the preferred combination of a resilient auger 316 and the above-described axial pre-loading is superior in controlling the level of force applied to the surface of the paintballs.
As previously described, two pairs of IR sensors measure the speed at which balls are passing through internal feed-tube sleeve 355, and adjust the rotation of auger 316 to maximize feed rate. Preferably, a third set of sensors, identified herein as auger sensor unit 432 sits at the rear of auger 316 and monitors its movement and position. Preferably, auger sensor unit 432 comprises a matched emitter/receiver pair 434 that is preferably mounted to main electronics board 392 and is preferably positioned adjacent power coupler 376, as shown.
Preferably, the emitter of the emitter/detector pair generates beam 435 that projects through power coupler 376 to the corresponding detector. Preferably, auger sensor unit 432 comprises an infrared (IR) emitter/detector pair preferably utilizing an infrared beam. Preferably, auger sensor unit 432 is electrically coupled with the control circuits of main electronics board 392. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as intended use, etc., other sensor arrangements, such as hall-effect sensors, shaft position encoder, etc., may suffice.

Preferably, axial translation of auger 316 is initiated by a buildup of pressure within the ball stack leading to paintball gun 104. As noted previously, this buildup in pressure is expected when paintball gun 104 is idled, the bolt is closed, and auger 316 is rotating under the power of rotator assembly 410. Alternately, a buildup in pressure is expected when auger 316 is rotating and a jam has occurred within the ball path. Preferably, a sufficient buildup in pressure results in the urging of auger 316 axially rearward to second position 424, as illustrated in
Referring to
Preferably, control of the operation of paintball loader 302 is provided by rotation-control subsystem 460 embodied by an embedded microcontroller unit (MCU 440) programmed to sample data from the onboard sensors, determine the optimum auger rotation, and implement such optimization using rotator assembly 410 to adjust the rotation of auger 316 (this arrangement at least embodies herein rotational-characteristics adjuster means for adjusting the rotational characteristics of such rotatable conveyer means based upon such operating conditions; and, this arrangement at least embodies herein at least one rotational-characteristics controller structured and arranged to control rotational characteristics of such at least one rotatable auger).

Preferably, rotation-control subsystem 460 automatically adjusts auger rotation to an optimum feed rate, without user intervention. Furthermore, rotation-control subsystem 460 automatically detects and clears paintball jams within the feed path.

A preferred embodiment of rotation-control subsystem 460 comprises a pulse width modulator using of one or more power MOSFETs under the control of MCU 440. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as user preference, intended use, etc., other control arrangements, such as feedback-loop control, open-loop control, digital potentiometer control, etc., may suffice.

Preferably, rotation-control subsystem 460 comprises non-volatile memory for non-volatile storage of the control software and other important variable data. The non-volatile memory preferably retains the information stored in it even when power is removed from the device. This preferred feature is enabled by the implementation of at least one nonvolatile memory device, which preferably includes such technology as Electrically-Erasable Programmable Read-Only Memory (EEPROM) modules or alternately preferably similar FLASH-based variants. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as intended use, etc., other arrangements, such as battery backup circuits, nonvolatile random access memory (RAM) chips, etc., may suffice.
Preferably, MCU 440 is operationally coupled to user interface electronics board 394. Preferably, user interface electronics board 394 comprises both user controls and visual indicators. More specifically, user interface electronics board 394 comprises green display indicator 470A, red display indicator 470B, and on/off switch 471, as best shown in
Preferably, operational power for both rotation-control subsystem 460 and rotator assembly 410 is provided by batteries 147. Preferably, alternate paintball loader 302 operates on four AA batteries, or alternately preferably, on two lithium ion camcorder batteries. Preferred Lithium ion camcorder batteries include KLIC 8000 digital camera batteries produced by the Kodak Corporation.

Preferably, the control software of rotation-control subsystem 460 is adapted to utilize sensor data from first detection unit 364, second detection unit 366, and auger sensor unit 432 to determine the optimum rotation of auger 316. Table A of
In first operational state 501, a flow is detected by first detection unit 364, no flow is detected by second detection unit 366, and auger sensor unit 432 indicates that auger 316 is in second position 424. Rotation-control subsystem 460 is preferably programmed to associate first operational state 501 with a ball jam within the feed path, as shown. In response to first operational state 501, rotation-control subsystem 460 initiates a single reverse revolution of auger 316 (to clear the paintball jam) and then preferably rotates auger 316 forward. Preferably, both green display indicator 470A and red display indicator 470B are illuminated in a flashing pattern to indicate to the user that a jam condition has occurred.
In second operational state 502, a flow is detected by first detection unit 364, no flow is detected by second detection unit 366, and auger sensor unit 432 indicates that auger 316 is rotating. Rotation-control subsystem 460 is preferably programmed to associate second operational state 502 with a “no ball” condition, as shown. This condition may occur when the paintballs within paintball storage compartment 310 have been expended. In response to second operational state 502, rotation-control subsystem 460 adjusts rotation of auger 316 alternately between a slow rotation speed and a medium rotation speed, as shown. Preferably, green display indicator 470A is illuminated in a flashing pattern to indicate to the user that paintball storage compartment 310 may be empty.
In third operational state 503, a flow is detected by first detection unit 364, a flow is detected by second detection unit 366, and auger sensor unit 432 indicates that auger 316 is rotating. Rotation-control subsystem 460 is preferably programmed to associate third operational state 503 with a “normal run” condition, as shown. In response to third operational state 503, rotation-control subsystem 460 adjusts rotation of auger 316 to full rotational speed, as shown. Preferably, green display indicator 470A is constantly illuminated to indicate to the user that operation of alternate paintball loader 302 is normal.
In fourth operational state 504, no flow is detected by first detection unit 364, no flow is detected by second detection unit 366, and auger sensor unit 432 indicates that auger 316 is in second position 424. Rotation-control subsystem 460 is preferably programmed to associate fourth operational state 504 with a “stack full” condition, as shown. A “stack full” condition occurs when paintball gun 104 is idled, the bolt is closed, and rotation of auger 316 against stack has urged auger 316 to second position 424. In response to fourth operational state 504, rotation-control subsystem 460 preferably stops rotation of auger 316 and occasionally “pulses” auger 316 using brief partial rotations, as shown. Preferably, green display indicator 470A is constantly illuminated to indicate to the user that operation of alternate paintball loader 302 is normal. The above-described preferred operation of rotation-control subsystem 460 greatly extends battery life by efficiently managing the use of motor 358, preferably deactivating motor 358 completely when paintball gun 104 is not firing.
In fifth operational state 505, no flow is detected by first detection unit 364, no flow is detected by second detection unit 366, and auger sensor unit 432 indicates that auger 316 is rotating. Rotation-control subsystem 460 is preferably programmed to associate fifth operational state 505 with a “no ball” condition, as shown. This condition may occur when the paintballs within paintball storage compartment 310 have been expended. In response to second operational state 502, rotation-control subsystem 460 adjusts rotation of auger 316 alternately between a slow rotation speed and a medium rotation speed, as shown. Preferably, green display indicator 470A is illuminated in a flashing pattern to indicate to the user that paintball storage compartment 310 is empty.
Thus, as illustrated above, rotation-control subsystem 460 is preferably programmed to automatically optimize the operation of alternate paintball loader 302 by quickly adjusting the rotation of auger 316, based on monitored sensor data. The preferred low mass of auger 316 allows motor 358 to quickly ramp-up to a selected rotation speed. The preferred use of three separate sensors (preferably monitoring ball flow, auger rotation, and auger position) allows rotation-control subsystem 460 to exhibit highly responsive operation characteristics, preferably adjusting the rotation of auger 316 to allow high-speed feeding with relatively low levels of force applied to the paintballs.
Preferably, control software 510, operating within MCU 440, processes a plurality of inputs, including, user inputs (the closing of on/off switch 471) within user interface electronics board 394, sensor inputs (first detection unit 364, second detection unit 366, and auger sensor unit 432).
Preferably, control software 510, operating within MCU 440, comprises algorithms adapted to generate a plurality of outputs, as a function of the above-described inputs and several other process factors, such as, for example, elapsed time, reference voltage, etc. Preferably, such outputs include the illumination of display indicators 470 within user interface electronics board 394, and outputs changing the operation of physical components directly related to fire control (rotator assembly 410).
Programming of MCU 440 to function as desired requires several steps. First control software 510 is coded to comprise the logical processes presented in the following flowchart. Next, the coded control software 510 is compiled. Finally, the compiled version of control software 510 is transferred into MCU 440.
Next, motor 358 is energized as indicated in preferred step 514. Next, display indicators 470, preferably comprising light emitting diodes (LED) are updated as indicated in preferred step 516.

From a user's standpoint, operation of alternate paintball loader 302 is initiated by depressing on/off switch 471 until the green display indicator 470A illuminates to indicate that the loader is operational. There is no need for the user to adjust any other operational settings as the preferred control arrangements enabled within rotation-control subsystem 460 automatically control the subsequent operation of alternate paintball loader 302, as further described below.
Next, decision step 518 is preferably executed within control software 510. In decision step 518, control software 510 determines the status of first detection unit 364. If a ball flow is detected, control software 510 enters preferred decision step 520. If a ball flow is not detected, control software 510 enters preferred decision step 522, as shown.
In decision step 520, control software 510 determines the status of second detection unit 366. If a ball flow is detected, control software 510 enters preferred decision step 524. If a ball flow is not detected, control software 510 enters preferred decision step 526, as shown.
In decision step 524, control software 510 determines the status of auger sensor unit 432.

In reference to preferred decision step 526, control software 510 preferably determines if the current draw by motor 358 exceeds a predetermined limit. Excess current draw by motor 358 is indicative of a full ball stack or the presence of a ball jam. This condition is preferably disambiguated by comparing additional sensor data. Preferably, the circuiting of main electronics board 392 is structured and arranged to sense current draw by motor 358, preferably utilizing a current monitoring sensor 395, as shown.
If the current draw by motor 358 exceeds a predetermined limit, control software 510 enters “ball jammed” step 532 and initiates a single reverse revolution of auger 316 (to clear the paintball jam) and then preferably rotates auger 316 forward, as indicated in preferred step 534. Preferably, on completion of preferred step 534, control software 510 immediately loops back to preferred step 516.
If the current draw by motor 358 does not exceed the predetermined limit, software 510 enters preferred decision step 536 wherein the status of auger rotation determined. In decision step 536, control software 510 determines the status of auger sensor unit 432. If an auger rotation is not detected, control software 510 enters “ball jammed” step 532, as shown.

Preferably, on completion of preferred step 534, control software 510 immediately loops back to preferred step 516.
In reference to preferred decision step 522, control software 510 preferably determines the status of second detection unit 366. If a ball flow is detected, control software 510 immediately returns to preferred decision step 518, as shown.
If in preferred decision step 522, a ball flow is not detected, control software 510 preferably adjusts the rotation rate of motor 358 to a slow speed, as indicated in preferred step 542, and immediately enters preferred decision step 544, as shown. In decision step 544, control software 510 determines the status of auger sensor unit 432. If an auger rotation is detected, control software 510 immediately returns to preferred decision step 518, as shown. If in decision step 544 an auger rotation is not detected, control software 510 enters “stack full” step 546 and stops the operation of motor 358, as indicated in preferred step 350. Within preferred step 548, control software 510 is further structured and arranged to initiate an occasional pulsing of motor 358, preferably resulting in a small rotation of auger 316. Preferably, on completion of preferred step 548, control software 510 enters preferred decision step 550, as shown.
In decision step 550, control software 510 again determines the status of auger sensor unit 432. If an auger rotation is detected, control software 510 immediately returns to preferred step 514, as shown. If in decision step 550 an auger rotation is not detected, control software 510 immediately loops to preferred step 548 wherein operation of motor 358 is stopped with the exception of the above-noted occasional pulsing.
