Definitions

  • roller accelerators and slide-in carriages thus form two Modules that work independently and can be controlled.
  • the roller accelerator does not allow to use the transfer vehicle in cooperation with the slide-in cart, for example, plates of great weight to be lifted off the plate stack by means of suction lifting elements and bypassing the roller accelerator on the Put down the machine table (not documented, state of the art of the applicant).
  • a development of the invention according to claim 2 enables es, movable carriers and transfer vehicles bypassing a plate transport by roller acceleration for the Transport heavy or with a sensitive surface Plates from the stack of plates directly on the machine table to be able to use.
  • the movable Carrier alone thicker single plates or plate packs from thinner individual plates from the plate stack over the Push the acceleration rollers away onto the machine table, in this case the transfer car in a corresponding Positioning above the machine table in Rest position can remain.
  • the loading device has a receptacle 10 for one to be stacked, for example formed from raw panels Plate stack 12 on.
  • This can be done, for example, by a Be lift table formed. Individual plates are to be taken from the raw plate stack 12 14 or plate packs on a machine table 16 a panel saw, not shown, are transported. This is done in a known manner either horizontally movable, not shown slide-in cart, with the corresponding lifting and lowering plate driving elements is equipped or, as shown, a movable, for plate transport above the raw plate stack 12 to be determined carrier 18, the plate feeder with several take-over take-away units 20, which work independently of the carrier 18 in such a way that by this takes place when the carrier 18 is shut down.
  • the carrier 18 is connected in a known manner Roller accelerator 22, which of the plate drive units 20 plates 14 pushed off the raw plate stack 12 detected and with increased transport speed to the machine table 16 feeds.
  • the roller accelerator 22 preferably has a plurality of axially spaced, drivable, lower acceleration rollers 24 as well as these in the same Number assigned and dedicated to plate transport with its axis essentially in the drive shaft 26 the vertical plane a-a receiving the acceleration rollers 24 located upper, lowerable pressure rollers 28.
  • the transfer carriage 30 also forms part of the roller accelerator 22 by its upper pressure rollers 28 on Transfer car 30 each by means of a cylinder unit 36 are raised and lowered in a suitable manner.
  • the transfer carriage 30 carries lifting and lowering Plate driving elements 38, each for example formed by the piston rod of a cylinder unit 40 could be. These are laterally to the upper pressure rollers 28 arranged so offset that they are in the vertical plane a-a down between the accelerating rollers 24 in their plate transport position are controllable. Also are the cylinder units 40, seen in the plate transport direction, preferably arranged behind the upper pressure rollers 28.
  • Cylinder units 40 and upper pressure rollers 28 are on a common crossbar 42 of the transfer carriage 30 held.
  • the acceleration rollers 24 or the machine table 16 are preferably vertically continuously adjustable, which is for the sake of simplicity is not shown.
  • the loading device is with the same strand 50 the toothed belt 48 in a suitable manner and in particular program-controlled, for example by clamping one Section of their run 50 between a clamping surface 60 and one adjustable by a linearly movable actuating wedge 62 Clamping jaw 64 of the wagons 18, 30 to be carried along detachable.
  • Actuating wedge 62 and jaw 64 are here in a common guide housing 66 of a coupling device 68 guided, which also has the clamping surface 60.
  • the transfer carriage 30 by automatically coupling to belt space 50 so far towards the one set in a push-off position Carrier 18 moved until the plate driving elements 38 are located behind the plate pack 52. After that, the Toothed belt 48 controlled in the opposite direction, then the plate pack 52 z. B. by the transfer vehicle 30 towards a z. B. pivotable upwards Plate stop 54 is moved.
  • the transfer carriage 30 can, as in the plate carrier unit shown 20 of the movable carrier 18 shown, in addition or also exclusively with a vacuum source connectable, e.g. B. by means of a cylinder unit 56th Suction heads 58 arranged to be raised and lowered be. This makes it possible to transfer the transfer carriage 30 also with the upper pressure rollers 28 raised above the Control plate stack 12 and by this in cooperation especially heavy with the suction heads 58 of the carrier 18 Lift off individual plates 14. Both are movable on it Units 18, 30 with the runs 50 of the two toothed belts 48 to couple and over the machine table 16 to the plate storage to drive.
  • roller accelerator according to the invention 22 thus does not constitute a barrier to transportation more for 16 plates to be pushed onto the machine table, by its lower accelerating rollers 24 through the plate 14 can be run over.
  • Toothed belt 48 cars to be driven together in the same Directions or individually, possibly by different Stretch, steer in opposite directions.
  • a third movable unit a usual, only with lifting and lowering drivers equipped transfer car form the plate feed to the panel sizing saw.
  • the construction of the guide frame 32 can also only have a horizontal guide rail on the underside the plate driving units 20 can be moved on one arranged cross member or at least one slide-in cart could be provided. In this case, a towing device for driving all units to be carried are enough.
