  • Patent number: 7828281
    Abstract: When a sheet is conveyed from a processing tray to a stacking tray, a bar-like pushing member is moved in a direction of the stacking tray in synchronization with an ejector. Consequently, simultaneously with the movement of the sheet by the ejector, a lower surface of a leading end of the sheet is pushed to relax and reduce a contact force between the lower surface of the leading end of the sheet and the stacking tray (or an upper surface of a sheet already stacked on the stacking tray). As a result, static friction at the leading end of the sheet is changed to dynamic friction and the entire sheet is conveyed to the stacking tray without bending.

  • Patent number: 5238237
    Abstract: In order to move a piece of fabric (1) over a work table (2) using a gantry robot (4), a gripper (7) comprising a flat foam-covered plate is lowered on to the fabric by the robot shaft (6). It is found that the best control over the fabric is obtained by allowing the gripper to rest on the fabric solely under its own weight, i.e. it should not be pressed down by the robot shaft. A flexible coupling (8) allows the gripper to float, while preventing relative rotation between the robot shaft and the gripper. The coupling is mounted to be movable up and down relative to the shaft, and a coupling part (13) to which the gripper is attached can tilt along two horizontal axes. When the gripper is raised, compressed air is introduced into the coupling, causing parts (11,15) of the two coupling members (10,13) to make contact, so that the gripper is held rigidly in a horizontal position. It is held in that attitude while it is lowered on to the fabric, and the pressure is then released.

  • Patent number: 5116037
    Abstract: An apparatus for the fault-free receiving and issue of sheets has guide rollers which are arranged on a carriage and which engage into belts to alter the geometry of the belts when the carriage is displaced on a rail over a stack by means of a drive. In the receiving or issue operation the sheet to be stacked or a top sheet to be issued rolls, without sliding, around one of the outer guide rollers, on the stack. Disposed between the outer guide rollers on a roller shaft are rotatable suction rollers whose suction cap sucks up the top sheet by means of reduced pressure at the beginnning of an issue cycle. A control arrangement is adapted to trigger off apparatus receiving and issue cycles and establishes predetermined positions of the carriage on the rail.

  • Patent number: 4982941
    Abstract: A jogging apparatus 22 has motor 24 mounted within a support frame 20. Motor 24 has a motor shaft 28 to which is connected hub 30. Projecting outwardly from motor hub 30 along an axis parallel to, but eccentrically offset from, the axis of motor shaft 28 is eccentric pin 34. Slotted link 32 slidably engages slot pins 36 and 38 in transverse slots 42 and 44 respectively of slotted link 32 for transverse movement of slotted link 32. Slotted link 32 also has an orthogonal slot 46 generally perpendicular to transverse slots 42 and 44. Eccentric pin 34 is slidably engaged within orthogonal slot 46 such that as motor shaft 28 is rotated, the rotational motion of shaft 28 is converted into the side-to-side motion of slotted link 32. Eccentric pin 34 projects somewhat beyond the outer surface of slotted link 32 and typically terminates in enlarged head 57. Enlarged head 57, with respect to orthogonal slot 46, describes an up and down movement within slot 46, as motor shaft 28 rotates.

  • Patent number: 4790224
    Abstract: A travelling slot cutting machine and method of cutting a workpiece upon the machine in which there are two independently operable and longitudinally aligned, endless conveyor belts, the adjacent ends of which are spaced apart to define a gap through which a cutting medium may be directed. To cut a workpiece supported over the gap, the cutting medium is directed through the gap while the cutting machine, as well as the gap, are moved longitudinally relative to the stationary workpiece. In moving the gap, the conveyors are clamped against movement over their respective supporting rollers. The supporting rollers are then moved in such a fashion that the length of at least one of the conveyor belts is maintained unchanged as the workpiece is transported from the upper run of one of the conveyor belts to the upper run of the other conveyor belts.
