Definitions

  • the invention relates to a method for unstacking nonferromagnetic boards by means of suction grippers arranged vertically and horizontally movable according to the preamble of claim 1 and a device for carrying out the method.
  • the invention is based on the problem of specifying a method and a device for carrying out the method according to which a functionally reliable, low-noise and inexpensive unstacking of boards made of non-ferromagnetic materials by means of compressed air is possible without mechanical influences on the boards, a high back pressure being generated and the direction of the air jet should also act on the board to be lifted during the lifting stroke of the suction pad.
  • the method can be implemented by the method steps mentioned in the characterizing part of patent claim 1. Further advantageous embodiments of the method are described in claims 2 to 6.
  • a device for performing the method can be implemented by the features described in the characterizing part of claim 7.
  • the features of claims 8 and 9 relate to further detailed configurations of the device.
  • the compressed air nozzle can also be automated for the respective board stack change.
  • the unstacking device (Fig. 1) consists in a simple embodiment of a frame-shaped frame 1 with guide rails 2 running in the transport direction, on which a carriage 3 is slidably mounted.
  • the carriage 3 is driven by mechanical coupling with the drive of the transfer device of the press 9 or by means of a separate drive motor in a known manner.
  • a crossbar 5 equipped with suction pads 4 is mounted by means of a separate drive and can be raised and lowered.
  • Below the suction gripper 4 at least one stacking trolley or stacking table 7 with a lifting device 8 loaded with a board stack 20 is provided.
  • the stanchions 6 stand firmly on the frame of the stacking table 7.
  • the lifting device 8 lifts the board stack 20 and guides it continuously during processing, so that the pick-up level is kept as constant as possible.
  • the stanchions 6 preferably each have a pivotable compressed air nozzle 10 at their upper end.
  • the lever 12 has a pneumatic pivot bearing 13 in its bearing point.
  • the nozzle mouthpiece 14 is specially designed and is displaceably mounted on the lever 12.
  • a compression spring 15 pushes it to the left to the stack of blanks 20.
  • the cross pin 16 holds the nozzle mouthpiece 14 in its end position facing the stack of blanks 20 and serves the compression spring 15 as an abutment.
  • An elongated hole is made for the cross pin 16 within the nozzle mouthpiece 14 in order to realize the displaceability of the nozzle mouthpiece 14.
  • the nozzle mouthpiece 14 is designed in its outer contours so that the Sealing surface 17 runs parallel to the outer edge of the board stack 20 and the bearing surface 18 comes to rest on the board stack 20, as shown in position I in FIG. 3.
  • the suction gripper 4 lifts the circuit board or several circuit boards into the control position (display of the control position with switch 11) and thus the compressed air nozzle 10 in position II. With a further upward stroke, the compressed air nozzle 10 arrives in position III, in which the circuit board bypasses it and from which pivots out of the compressed air nozzle 10 again by its own weight.
  • the sloping surface 19 of the nozzle mouthpiece 14 slides onto the stack edge and pushes the nozzle mouthpiece 14 back until the sealing surface 17 abuts the outer surface of the stack.
  • the compressed air nozzle 10 pivots further down until the support surface 18 rests on the stack surface.
  • the outlet opening for the air jet in the nozzle mouthpiece 14 is preferably elongated, so that an air jet plume is created.
