This application claims the benefit of U.S. Provisional Application No. 60/551,508, filed on Mar. 9, 2004, hereby incorporated herein in its entirety by reference.
FIELDThe present invention relates generally to digital discs and in particular the present invention relates to processing and handling of digital discs.
BACKGROUNDDigital discs are used as a storage medium for digital information. The data is stored on the disc by varying the optical characteristics of the disc. This digital information can be any type of data, such as, but not limited to, audio, image, photo and/or video information. In other words, the digital data stored on a compact disc can vary from disc to disc. Different types of compact discs can be provided, a traditional type of compact disc is manufactured using a plastic mold operation. Each compact disc manufactured using the same mold contains the same digital information. As such, large production runs of compact discs which contain the same information, such as a musical composition, are manufactured in an economical manner by using a molding process.
A different type of compact disc which is commercially available is a recordable compact disc. This type of disc is manufactured such that it does not contain data thereon, but can be programmed after it is manufactured. The optical characteristics, therefore, of the compact disc are modified after it is fabricated depending upon the data that is stored on the disc. In the context of the present invention, it is to be understood that reference to a compact disc (CD) includes but is not limited to Compact Disc Recordable “CD-R”, Compact Disc Readable “CD-RW”, CD-ROM, CD-PROM, Digital Versatile Disc “DVD”, DVD-R, DVD+R, DVD-RAM, DVD-RW, DVD+RW, or any disc for data storage.
To identify the data stored on a compact disc, a label is often printed on one side of the compact disc. For large manufacturing runs of a common compact disc, a silk screen process is often used to apply the label to the compact disc. For small production runs of compact discs, such as those using recordable compact discs, a silk screen operation may not be economical. A custom printing operation, therefore, can be employed to print a custom label on each compact disc. See for example U.S. Pat. No. 5,734,629 entitled “CD Transporter” issued Mar. 31, 1988 for a description of a compact disc transporter which can be used to move a compact disc between a data recorder and a printer, and which allows for automated processing of recordable compact discs. This transporter moves a single compact disc at a time between stations and places completed compact discs in a stack.
Many transporters require an active picker or gripper for moving compact discs between the various components of a transporter. This adds to complexity and cost of such transporters. For small runs of compact discs, such transporters may not be economical. Further, many transporters are large and do not fit well within a small office of home environment.
Still further, typical loading and unloading systems using pickers have recorder downtime due to a picker which is feeding the recorder having multiple tasks to accomplish. For example, a disc to be recorded is placed in a recorder by a picker. When the recording is finished, the tray opens, and the picker moves the disc to the next station or component of the device. Then, the picker retrieves a blank disc for recording and places it in the recorder. During the time that the picker is moving the first disc and retrieving the second disc, the recorder sits idle.
There are many different CD and DVD recorders and readers. Many manufacturers make such products. In a transporter, there are often precise placements and orientations that are needed so that disc production is smooth and requires little if any intervention by a user once the process has started. Typical transporters require precision hand placement of recorders and the like into position within a system, further adding to the labor required to produce and modify such systems. Manufacturers are also continuously striving to upgrade drives to make them more efficient and faster. As each upgrade evolves, often the dimensions of the recorders change. While this change may not be large, the precision placement of recorders in transporters may lead to difficulty for a user wishing to replace a drive.
For the reasons stated above, and for other reasons stated below which will become apparent to those skilled in the art upon reading and understanding the present specification, there is a need in the art for a transporter having a small footprint, and for a transporter that provides reliable yet economical service. There is a further need in the art for a simplified process for mounting a new or upgraded drive within a transporter system.
SUMMARYThe above-mentioned problems with drive replacement, size and cost of transporters, and other problems are addressed by the present invention and will be understood by reading and studying the following specification.
BRIEF DESCRIPTION OF DRAWINGS
In the following detailed description of the invention, reference is made to the accompanying drawings that form a part hereof, and in which is shown, by way of illustration, specific embodiments in which the invention may be practiced. In the drawings, like numerals describe substantially similar components throughout the several views. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments may be utilized and structural, logical, and electrical changes may be made without departing from the scope of the present invention.
The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled.
The various embodiments of the present invention have the capability, among other things, to record and print on CDs, and to do so without an active picker. Further, the embodiments of the present invention reduce idle time for a recorder. This is accomplished in various embodiments by providing a gravity feed delivery system of discs to a recorder, and using an angled motion picker to move discs.
As is shown in
Discs can rock and move out of proper picking orientation when stacked, especially when stacked substantially vertically. In a near vertical orientation, the bottom of a stack of discs has forces that tend to push the discs outward in the direction of arrow 155 shown in
Referring now to
The singulator 200 is described in greater detail also referring to
Any suitable movement mechanism for creating a linear movement of the singulator arm 204 and singulating member 202 is sufficient for the purposes of the embodiments of the singulator 200. Those skilled in the art will immediately recognize that such drive mechanisms include by way of example only and not by way of limitation, to rack and pinion mechanisms, pulley and belt mechanisms, geared drive mechanisms, and the like.
In operation, the singulator 200 works as follows. The singulator is actuated and moves the singulator arm 204 to a position in which the singulating member 202 has its flat surface 208 extended within a center opening of a disc. The sizing of the singulating member and its position within the arm 204 is designed so that a single disc is in contact with the flat surface 208 when the singulator arm 204 is in this position (see
Feed chute 250 is in one embodiment configured as a portion of input bin 100. In other embodiments, feed chute 250 may be a stand alone chute, or may alternatively be a part of a singulator such as singulator 200, or of an entire apparatus, without departing from the scope of the invention.
Feed chute 250 comprises in one embodiment a angled back member 252 and side walls 254. In conjunction with a singulator such as singulator 200, the chute functions to feed by way of gravity, a disc from the singulator 200 to a tray 272 of recorder or verifier device 270. When the disc is dropped off of the flat surface 208 of the singulating member 202, the disc falls into chute 250, and slides along back member 252 and between side walls 254. Gravity pulls the disc downward into the chute, and the chute directs the disc to a waiting tray such as tray 272. As such, no active picker is required to position a disc into a recorder or the like.
Once the disc is in the recorder or the like, it is recorded, or written, or rewritten, as is desired. When that process has completed, the tray 272 opens once again, and the disc is transported by a picker to its next destination in the apparatus.
On embodiment of a system 300 for mounting drives such as recorder or verifier 270 is shown in greater detail in
A side elevation view of the sleeve 302 of
Another embodiment of a sleeve 350 is shown in
One embodiment of a multi media printer 400 is shown in greater detail in
One embodiment of an angled motion picker 440 is shown in greater detail in
Belt and pulley drive 406 comprises belt 432 moved by motion of pulley members 434. Clip 460 is affixed to belt 432 and moves when belt 432 moves. Clip 460 is connected to and moves with arm 470, which houses actuator 480 and gripping finger 490 as shown in greater detail in
As has been mentioned, picker body 450 is fastened via clip 460 to belt 432 of belt and pulley system 406. Arm 470, connected to clip 460, rides along linear rail 410, with arm 470 having an opening through which linear rail 410 passes so as to maintain alignment and movement of picker body 450 in a linear motion parallel to the axis of linear rail 410. Referring now also to
To set the actuator into the notches 466 and 468, it is necessary in one embodiment to overdrive the belt once the respective arm member 475 or 477 has contacted the respective stop member 438 or 436 of belt and pulley system 406, forcing the clip 460 to continue to move relative to the now stationary arm 470. Since translational motion of the picker body 450 stops when the arm 470 hits the stop member 438 or 436, the overdriving of the belt 432 and hence the clip 460 forces the actuator to slide along the surface 469 between the two notches 464 and 466 until it snaps into the other notch. Overdriving the belt when the arm 470 reaches stop member 438 results in releasing gripping by the gripping finger by snapping the actuator 480 from notch 466 to notch 468. This action pivots actuator 480 about pivot point 486 in the direction of arrows 489. In contrast, overdriving the belt when the arm 470 reaches stop member 436 results in engaging gripping by the gripping finger by snapping the actuator from notch 468 to notch 466. This action pivots actuator 480 about pivot point 486 in the direction of arrows 488. A spring (not shown) may be used to assist in the retraction of the actuator.
In operation, the system 400 operates as follows. A stack of discs to be recorded and/or printed is stacked in the input bin. The configuration of the input bin forces a few discs of the stack into proper singulating position. The singulator operates to pick a single disc from the back of the input bin, lifting the disc by its center opening until a predetermined point is reached, where the singulating member retracts, and the disc is released. The disc falls into the feed chute, and drops into open recording tray of the recorder. Once recording is complete, the picker is placed in its gripping position, and removes the disc from the recorder tray. At this time, the singulator has been instructed to singulate another disc from the input bin, and once the disc from the recorder tray is picked, the singulator drops another disc into the recording tray. The recording tray retracts, and the picker body moves along the linear rail to its release position, where the disc is released, either to the printer or to the output bin (described below). The process shortens idle time for the recorder by removing picking as a requirement for placing a disc in the recorder.
Another embodiment of an arm 500 is shown in
It should be understood that other transmitting and detecting schemes are within the scope of the invention, including by way of example only and not by way of limitation, visible light, laser light, and the like.
One embodiment of an output bin 600 is shown in greater detail in
It should be understood that in other embodiments, the mechanism by which output bin 600 rotates can be changed without departing from the scope of the invention. For example, in another embodiment, the output bin is motorized to move between its first and second positions. In this embodiment, the system 400 tracks the number of discs that have been deposited in output bin 600. Once a predetermined number of discs is reached, the motor lowers the output bin for disc retrieval. It should be understood that a straight angled drop could also be used, eliminating an output bin altogether, without departing from the scope of the invention.
In another embodiment, a spring loaded door 750 is positioned in the arc of a disc that is being picked up from its leaning position described above. The door 750 is biased by a coil spring 752 or the like to the position shown in
In one embodiment, computer 802 runs a software program that identifies the system 804 by polling the components connected to the USB hub 810, and identifying the system by the configuration of components.
It should be understood that the number of recorders in systems of the present invention can be increased without departing from the scope of the invention. The motion of the picker body and the passive nature of the device are best embodied in a system with two locations for the picker to move between, but modifications will be apparent to those of skill in the art, and such modifications are within the scope of the invention. Further, the various components of the present invention need not all be present on any system, and individual components of the present invention are amenable to use on other systems. For example, a gravity feed chute and singulator can be used on a system with an active picker, or a passive picker may be used on a system without a singulator of the present type, and so forth, without departing from the scope of the invention.
CONCLUSIONA system, components, and processes have been described that include an input bin, a singulator, a gravity feed system for discs, a passive picker that requires no electronics for operation, a drive mounting system that mounts multiple drives without the need for hand adjustment, a belt picker for a printer or the like, and an output bin, as well as a system incorporating the individual components. The system and processes reduce idle time for a recorder of the system, and reduces the need for an active picker, thereby reducing cost while improving efficiency.
Although specific embodiments have been illustrated and described herein, it will be appreciated by those of ordinary skill in the art that any arrangement, which is calculated to achieve the same purpose, may be substituted for the specific embodiment shown. This application is intended to cover any adaptations or variations of the present invention. Therefore, it is manifestly intended that this invention be limited only by the claims and the equivalents thereof.
