  • Patent number: 4624360
    Abstract: A method and apparatus for slipping tubes on pegs carried on a transport belt which extends along a spinning machine or twisting machine. A slipping-on apparatus for said tubes is located above the transport belt and inserts the tubes on the pegs. A sensing device monitors the seating of the tubes on the pegs and a lifting off device removes the tubes that are improperly seated on the pegs. After an improperly seated tube is removed from the peg, another tube is inserted thereon.

  • Patent number: 4618052
    Abstract: A lane divider for the conveying of can body cylinders maintains the cylinders in line-ahead formation and in a predetermined orientation, e.g. with their welded side seams uppermost, by maintaining a positive hold on each cylinder at all times during its travel along a feed path and during transfer from the feed path to, and subsequent travel along, a plurality of downstream paths selected by a sequential control unit responsive to the arrival of a cylinder in the feed path. Control of cylinder orientation is obtained by an array of magnets along each path; these include electromagnets in the region of the junction of the paths. Path selection is obtained by selective energisation of the electromagnets.

  • Patent number: 4610597
    Abstract: A mechanical interface for joining a gripper to a robot wrist of the type having a shaft projecting outwardly as the distal member of a robot arm. The interface includes a sleeve having an internal nut or flange for properly locating the sleeve with respect to the shaft. At this location, a bevel gear at the end of the shaft engages a similar gear within the sleeve so that the sleeve is locked to the shaft. The bevel gear within the sleeve is supported by a spring so that outward force from the sleeve allows separation of the gears and disconnection of the coupler from the shaft. Internal fluid passageways within the sleeve allow transmission of fluid pressure from the shaft to a connected gripper for transmitting power, control signals or sensing signals between the robot arm and the gripper.

  • Patent number: 4610591
    Abstract: A control device for feeding metal bars to guide equipment for feeding an automatic multiple-spindle lathe. The device consists of a series of drive shafts, each of which accounts for the feeding of a bar. The shafts are equal in number to the lathe spindles and are placed in a drum that rotates synchronously with the lathe spindle holding drum. Each of these shafts can be coupled with a drive element when a certain length of bar is to be fed. The coupling takes place through engaging and disengaging parts mounted between the shaft and the drive element. Each shaft controls at least one gear for feeding a bar, through a chain or the like provided with a bar-pusher, when the shaft is made to turn. The gear can be moved to make the device usable with lathes having different spindle center distances.

  • Patent number: 4609322
    Abstract: Earthmoving vehicles are often provided with a linkage arrangement on one end that is utilized to manipulate a work implement, such as a loader bucket. The linkage typically includes a tilting arrangment for the bucket that incorporates a tilt lever that is mounted to a lift arm that supports the bucket. The mounting between the tilt lever and the lift arm is normally of a complex nature requiring multiple bearing surfaces and lubrication means. Others may have a structure that requires exact positioning between the relative components or a failure will occur due to improper loading. The linkage arrangement of the present invention provides a mounting member that is attached to only one of the tilt levers. It also includes an axial motion limiter that is attached to the other tilt lever. In doing so, a very simple and economical mounting device is provided. The mounting device also allows the tilt levers to rotate with respect to each other so that each of the levers function to bear a portion of the loading.

  • Patent number: 4605354
    Abstract: A resilient gripper pad stores deformation energy just before the gripped object starts to slip, then rapidly accelerates as it suddenly releases the energy in the springback to rest position. An accelerometer in the resilient pad (corrected for ambient acceleration by differentiation with a nearby second accelerometer) provides information by which the control computer of a closed loop robot system mandates the manipulation of objects by controlled slipping. Controlled transitions of gripping (releasing) action evoked by the control computer provide related sequences of grip (slide) events, with one or more slip (pad chatter) events intervening at the threshold. Prior to the slide, there is an instant when the gripped object starts to slip on a slip pad on one digit of the gripper, but remains frictionally gripped by a resilient pad on the opposing digit. During this instant, the resilient pad deforms downward because of gravity on the gripped object.

  • Patent number: 4593809
    Abstract: A machine for connecting successive rows of coil springs together into a coil spring assembly. The machine, in preferred form, initially picks up a row of coil springs by inserting a pick up finger into the barrel of each coil and moving the springs onto a support platen. In the course of transporting the coils between pick up and the support platen, the pick up fingers change the spacing of the coils. The springs are then compressed against the support platen to a desired height through use of a reciprocable compression bar. Thereafter, and through use of rotatable transfer fingers on a transfer shaft, the springs are removed from under the compression bar, and are moved into clamping dies. Leading rotary transfer fingers on the transfer shaft first pull the row of springs out from under the compression bar, and trailing rotary fingers then push the springs into the downstream one of upper and lower clamping dies.
