  • Publication number: 20030183485
    Abstract: A device (1) to feed work pieces in steps, for example within a press (2), using two gripping rails (3) that can be moved back and forth in the feed direction, that includes at least one feed traverse (8) that moves perpendicular to itself with which to uniformly feed and return the gripping rails (3). Coupled to this traverse is at least one tilt arm (9) that is driven by a servomotor (11) whose tilt motion is converted to the perpendicular motion of the feed traverse (8) and thus into the feed and return motion of the gripping rails (3). There can also be two tilt arms (9) arranged in a mirror-image fashion.

  • Patent number: 6622850
    Abstract: With an advancing motion, finger plates together with stationary transfer bars are moved to positions where uprights are not in the way, and finally the finger plates disengaged from the stationary transfer bars are held by plate holding members to be discharged to an area where preparatory work is conducted externally of a transfer feeder, together with movable transfer bars. Accordingly, inherent motions of the transfer feeder are made use of to shunt the finger plates, and as compared with the case where the finger plates are disengaged from the stationary transfer bars at standstill to shunt, cylinders for movement and guide rails are dispensed with to enable attaining light weight and the transfer feeder is enhanced in operating rate.

  • Patent number: 6607070
    Abstract: A method for transferring book blocks or the like into a transport device of a bookbinding machine. The book block is first clamped in a force-locking manner. At least one corner of the back edge or of the front edge of the book block is aligned with a position, which can be set in a predefined manner, by relative displacement of the two sides of the book block in the plane of the book block. The book block is then clamped in a force-locking manner by the transport device.

  • Patent number: 6604402
    Abstract: A transfer device combines an advance-return drive mechanism and a clamp-unclamp drive mechanism. The transfer device operates from only one side of a press to position both drive mechanisms above a pair of feed bars thereby greatly reducing spatial constraints and costs and enabling an increase in speed. The feed bars operate to process a work piece along a process direction. The feed bars are cantilevered from the transfer device for easy use with a press, raw materials feeder, and product gatherer.

  • Publication number: 20030051980
    Abstract: A work piece transfer assembly (10) for moving a work piece (12) through and between presses comprises a transfer mechanism (14) moveable in a longitudinal (60), a lateral (62), and a vertical direction (64) and having a first end (16) and a second end (18) for supporting at least one main transfer bar (20). The main transfer bar (20) has a predetermined length (22) with a support mechanism (24) attached thereto for supporting a sub-transfer bar (26). The sub-transfer bar (26) includes a plurality of fingers (28) extending from the sub-transfer bar (26) for engaging and moving the work piece (12) between the presses. The support mechanism (24) includes a cradle (30) fixedly attached to the transfer bars (20). The cradle (30) also includes an alignment sub-assembly (38) for securing the sub-transfer bar (26) into the cradle (30) and precisely aligns said sub-transfer bar upon each re-attachment of the sub-transfer bar (26) to the cradle (30).

  • Patent number: 6327888
    Abstract: A transfer apparatus is proposed for transferring workpieces between die stations comprising a striker cam driver by a press ram, a rotary gear urged to rotate by the striker cam, a shaft extending from the rotary gear and characterized by a distal end, and a finger bar pivotally coupled to the distal end and assuming arcuate travel above the die stations in response to rotation of the rotary gear. The transfer apparatus can further comprise a linear cam including a slot, a pusher plate including a cam follower extending therefrom and disposed in the slot, moveable horizontally in response to vertical displacement of the linear cam, and a finger bar, moveable into and out of engagement with the workpieces, in response to the horizontal movement of the pusher plate.

  • Patent number: 6314786
    Abstract: A transfer system, particularly for a press facility, has a guiding device on which workpiece holding devices are longitudinally displaceably disposed which belong to two different groups. The longitudinal displacement takes place by way of a driving device which is carried at least partially by the guiding device.

  • Patent number: 6234302
    Abstract: A transfer system has at least one transfer device which is driven by several mutually independent drives in the direction of at least a closing/opening axis. In the event of a failure of a drive, an immediate stoppage of parts of the transfer device is prevented by coupling the drives with one another by a coupling device. This coupling device has an operating range of a low torque transmission which is normally taken up and is left only if one of the drives no longer supplies a sufficient driving power.

  • Patent number: 6185979
    Abstract: A transfer system is provided for press facilities with several successive press stations. The transfer system has divided cross traverses which, with respect to the transport direction, can be moved from the front and the rear into the tool. Each tool includes two respectively transversely divided traverses. For receiving and depositing the workpieces, the cross traverses are adjusted toward and away from one another. In addition, when the tool is closed, the cross traverse are laterally moved past the tool. As required, they may be changed for this purpose into an overtaking position, which can be carried out, for example, by a swivel drive. The transfer system permits a shortening of the minimum time for which the tools must be open with respect to the transfer system and thus allows an increase of the stroke number of the press.

  • Patent number: 6176365
    Abstract: A control device for electric direct drives of a transfer system contains at least one monitoring device which, in the case of the malfunctioning of a direct drive, switches the control device into an emergency operating mode. In the emergency operating mode, the control device disconnects the linear drive affected by the malfunction from power and controls the remaining direct drives preferably at full power or at a slightly higher power. Thereby, a freedom from collision is established between the forming tool and the transfer device, after which the press is preferably stopped.
