Definitions

  • the invention relates to a device for removing sheets from a stack and to transport the sheets away from the stack with a machine-definable frame, with an over rollers on the frame side can be tensioned and endlessly rotating Timing belt, one between two adjacent teeth Chamber forms, each of which is substantially centered Tooth longitudinal extension has an opening, with a frame-side guide block, which is a guide surface for the timing belt, with two equally large, on an axis protruding from the frame to form a Space between coaxially and rotatably mounted discs, that are 1.5 to 5 times the diameter which is the roller, and which are arranged so that their Circumferential surfaces on the inlet side of the toothed belt in the Guide block touch its guide surface and on a correspondingly shaped top of the guide block rotatable are recorded with one in the space between the inner end faces of the discs extending web of Guide block, in which a toothed belt inlet side Sheet transport direction extending, the openings in the toothed belt associated recess is formed
  • the guide block has a groove in its guide surface, whose depth to the groove bottom is essentially the strength of the Timing belt and its width essentially its width corresponds, whereby the chambers are laterally limited.
  • the distance between the outer end faces of the discs is dimensioned that it corresponds to the width of the groove, the peripheral surfaces of the pulleys on the inlet side of the toothed belt in the Guide block touch the groove bottom.
  • a bridge of the guide block In the space extends between the inner end faces of the disks a bridge of the guide block.
  • Suction channel formed with a to the guide surface in essentially vertical suction opening opens into the recess.
  • the suction channel of the guide block is via one valve and one Control device can be connected to a vacuum source.
  • EP 0 155 475 B1 already has one with a toothed belt cooperating guide block known in the direction of the toothed belt is adjustable with respect to the stack. This allows you to change the spatial assignment without changing of the device carrying the sheet stack and that of the Device discharged sheet receiving device, usually an alignment table, the length of the transport route above the sheet receiving device. If such a horizontally displaceable guide block is provided spring-loaded tensioners must be attached for the toothed belt will. There is a lot of wear on the toothed belt and its straight running is difficult to control.
  • the object underlying the invention is therefore in the device of the type described above to design that all sheet formats, including rounded and very short bends that can be at an angle to the toothed belt, trouble-free removed from the stack and transported away can.
  • the suction point can be optimally related adjust the shape and format of the sheets to be removed from the stack, even with the timing belt running and itself rotating disks and rollers what the setting of the device on sheet form and sheet format considerably simplified and after optimizing the setting, the perfect sheet acceptance and ensures trouble-free sheet transport.
  • the circumferential surface of the segment expediently extends over an angle of 40 ° to 70 °, preferably 50 °.

  • an external thread on a rod engages with one thread-free end rotatable in one approach Frame is supported on one side of the pin, in threaded engagement with a frame-side guide on the other Side of the pin stands and at its other end a rotating element wearing.
  • the device shown in the drawings has a drive roller 3, a tension roller 4, a guide roller 5 and two Discs 32 and 33 over which an endless toothed belt 15 is guided is. All components mentioned are made of one plate composite frame 8 set or stored on a machine part, not shown, can be determined.
  • the device is with respect to a stack 1 of sheet 2 with the Discs 32 and 33 in suction distance above the top one Sheet 2 of the stack 1 arranged as shown in Fig. 1 is.
  • a fixed to the frame 8 guide block 11 has one the toothed belt 15 facing flat, substantially horizontal Guide surface 16 while its opposite top 19 circular in the area of the disks 32 and 33 is that the peripheral surfaces of the washers 32 and 33 non-contact, but very close to the top 19 of the guide block 11 can circulate.
  • the leadership block 11 thereby extends with a web 34 under and between the disks 32 and 33 to where the peripheral surface of the disks 32 and 33, the guide surface 16 of the guide block 11 or its web 34 tangent.
  • the endlessly circulating toothed belt 15 has, as in FIG. 3, too is seen from one of the guide surface 16 facing flat band protruding, arranged at the same distance Teeth that form chambers 22 between themselves, which in themselves its webs extending in the longitudinal direction are delimited at the end are.
  • Teeth that form chambers 22 between themselves, which in themselves its webs extending in the longitudinal direction are delimited at the end are.
  • In each of the chambers 22 opens one through the band surface through opening 17, which is on the center of the tooth longitudinal extension is provided.
  • These openings 17 is a recess 20 extending in the direction of sheet travel Web 34 of the guide block 14 assigned from the inlet side the timing belt 15 starts.
