  • these mechanical extension profiles 48 are used in different lengths in the control block 14 and assigned to the locking slides 22 accordingly.
  • the individual piston-cylinder units are present as special cylinders on both sides of the control block 14 and are individually controlled by control valves 26.
  • These special cylinders are arranged within the machine, for example in housings 38, each with four piston-cylinder units, to protect them from damage or access.
  • These housings 38 contain the complete electronic and pneumatic control (valve islands, pressure regulators, pressure monitoring, etc.).
  • These housings 38 are connected to the valve device 26 with their individually assigned control valves by means of a coupling system designed for this purpose.
  • the control valves of the valve device 26 can also be flexibly mounted on appropriate transport frames in order to use them on different punching machines. This means you don’t just have to rely on one work area.
  • FIG. 9 A first drive unit 70 and a second drive unit 72 are still shown in highly schematic form. These two drive units 70, 72 are controlled and activated or deactivated by the control device 30 before each punching/perforation stroke H.

  • the frame device 130 with material unit M carries out a displacement in the transport direction T with the currently specified size.
  • the frame device 130 with material unit M carries out a movement in the transverse direction Q in the currently specified size.
  • the frame device 130 with material unit M can be arranged both in the transport direction T and in the transverse direction Q individually for each punching/perforation stroke H relative to the punching/perforation tool 12, almost any punching/perforation pattern can be generated.
  • different hole diameters can also be produced by means of perforating needles 16 of different diameters arranged in the punching/perforation tool 12 and by correspondingly moving the frame device 10 with material unit M.
  • the perforation position is determined before the respective punching/perforation stroke H
  • the nearest perforating needles with the corresponding diameter are determined and the material unit M is shifted by the corresponding amount.
  • any feeds in the transport direction T and in the transverse direction Q can be driven depending on the system by coupling the frame device 130 with the material unit M to the first and second drive units 70, 72.
  • FIG. 12 an exemplary embodiment of a processing system 100 is shown in a highly schematic manner, which shows the use of the frame device 130 in different processing operations.
  • first processing station 134 which is designed as a punching/perforating machine 10.
  • second processing station 150 which is a sewing machine 151, for example.
  • another processing station 160 may be present for further processing.
  • a first buffer 112 is connected in front of the first processing station 134, in which individual frame devices 130 are stored, each with a clamped material unit M without a punching/perforation pattern.
  • the frame devices 130 are individually removed from this first buffer 112 and fed to the perforation machine 10, which produces my punching/perforation pattern 66 in the material unit.
  • the frame device 130 with the perforated/punched material unit is then stored in a second buffer 114.
  • the frame devices 130 are then removed from the second buffer 114 and fed to the second processing station 150 or the sewing machine 151 and inserted into a transport frame 124 (sewing material holder).
  • the sewing machine 151 then produces, for example, decorative seams 68 on the punched/perforated material unit M.
  • the material unit M processed in this way with the frame device 130 is then stored in a third buffer 116 and can be removed for processing in a further processing station 160.
  • the frame devices 130 can be removed from the buffer storage 112, 114, 116, for example via in Fig. 12 Very schematically shown handling units 152, 154, 156, 158 are carried out, which also remove the processed frame device 130 from the processing stations 134,150 for storage in the buffer 114,116.
  • the handling units 152, 154, 156, 158 can, for example, be robot units that are equipped with corresponding gripper units.
