Definitions

  • the present invention relates to a method for preparing sheet metal pieces for drawing into a sheet metal bending machine and a combination of a device for preparing sheet metal pieces for drawing into a sheet metal bending machine with the sheet metal bending machine and with a side feed device for drawing the sheet metal pieces into the sheet metal bending machine.
  • the sheet metal bending machine is preferably a long bending machine, which can be designed as a single bender for bending in just one bending direction or as a double bender for optional bending in two opposite bending directions.
  • a sheet metal bending machine designed as a double bender in the form of a long bending machine has a so-called side feed device that grips a piece of sheet metal 5 to be fed into the sheet metal bending machine with the help of suction cups 51 and draws it into the sheet metal bending machine from the side.
  • the suction cups 51 cannot move in the horizontal depth direction of the sheet metal bending machine transversely to the bending edge formed by the lower beam 21 or upper beam 23.
  • the sheet metal piece 5 to be drawn in is provided on a fixed table top 80 of a transfer table.
  • the sheet metal piece 5 is pressed against stops 12 acting in the aforementioned depth direction.
  • Sheet metal pieces to be processed are usually cut in strip form using conventional longitudinal and transverse cutting devices from a sheet metal web that has previously been wound onto a coil.
  • the longitudinal and transverse cutting device places the cut sheet metal strips parallel to one another on the table top of a transfer table.
  • This transfer table can then be brought up to the sheet metal bending machine and coupled to it in such a way that its table top is fixed relative to the bending machine.
  • the sheet metal strips are stacked on top of each other by hand.
  • the stack of several sheet metal strips can then be pushed against stops 12 of the EP 3 778 048 A1 mentioned type to ensure that the suction cups 51 can always access the topmost sheet metal strip of the stack at the same point on the table top 80.
  • a method for preparing preferably strip-shaped sheet metal pieces for drawing into a sheet metal bending machine by means of a side-pull device.
  • the sheet metal pieces are arranged at least partially next to one another on a flat storage surface.
  • Partially arranged next to one another in this sense means that not only a single layer of sheet metal pieces can be arranged next to one another, but that instead several stacks each consisting of several sheet metal pieces can be arranged next to one another.
  • nine sheet metal pieces on the storage surface are conceivable, whereby these can lie on the storage surface in a total of three stacks of three sheet metal pieces each. In this case, only some of the total of nine sheet metal pieces lie next to one another on the storage surface.
  • the side feed device is arranged on the sheet metal bending machine, preferably on the upper part of the sheet metal bending machine, which can be pivoted about a horizontal axis.
  • the side feed device has a receiving device that can be moved into the sheet metal bending machine, for example in the form of one or more suction cups, which serves to receive a piece of sheet metal to be fed into the sheet metal bending machine at a receiving position that can be approached preferably horizontally by the receiving device and is preferably located vertically above the storage area.

  • Manual stacking of sheet metal pieces that were previously lying next to each other on the support surface is no longer necessary. Stops protruding upwards from the support surface are also no longer required.
  • the respective movement or movement of the support surface is completely automated with the help of the electronic machine control device and therefore saves time.
  • the position can advantageously be detected according to step a) by optically detecting reference edges of the sheet metal piece to be drawn in.
  • the information about the position of the reference edges relative to a reference point, a reference line or a reference edge is made available to the electronic machine control device by means of wired or wireless data transmission.
  • one or more cameras are used to optically detect the reference edges.
  • An individual order identification for example in the form of a printed barcode or a printed QR code, can be attached to each piece of sheet metal to be processed.
  • the order identification is linked to individual information for specifying a bending order to be carried out.
  • This order identification is preferably optically recorded when the piece of sheet metal is lying on the support surface and a signal representing the order identification is transmitted wired or wirelessly to the machine control device of the sheet metal bending machine.
  • the machine control device can then cause the bending order to be carried out by the sheet metal bending machine after the piece of sheet metal has been drawn in, in accordance with the individual information for specifying the bending order to be carried out.

For example, it is conceivable that the piece of sheet metal that is located the least far from the pick-up position of the pick-up device is picked up from the storage area. However, it is also conceivable that the order markings of several pieces of sheet metal lying next to each other on the storage area contain information about the order in which the pieces of sheet metal are picked up and pulled in.

  • an electronic machine control device is also provided which is designed to cause the motor drive device to move the support surface with the sheet metal piece to be drawn in located thereon relative to the sheet metal bending machine when the device is coupled to the sheet metal bending machine. This movement takes place in such a way that the sheet metal piece comes to lie at least partially vertically below the receiving position that can be approached by the receiving device in order to be picked up there by the receiving device.
  • the machine control device does not initiate the aforementioned movement of the support surface if the comparator device has previously determined that the sheet metal piece to be drawn in is already located below the predetermined receiving position of the receiving device.

  • the cameras 17, 18 can optically read order markings applied to the sheet metal pieces 4, 5 and 6 and make them available to the machine control device.
  • the order markings can be, for example, individual barcodes or QR codes printed on the surfaces of the sheet metal pieces 4, 5 and 6, which are linked to individual order data of a bending order.
  • order data can in particular include the position of bending edges, the length of bending legs and the size of bending angles on the bent sheet metal parts to be produced. This advantageously eliminates the need for a machine operator to enter such data into a machine input device.
