Definitions

  • the punching beam is not held in a frame in a rotationally fixed manner. Rather, the punching beam is mounted via a pendulum joint, which enables the punching beam to pivot relative to the frame in which the punching beam is held.
  • the pendulum axis is aligned transversely to the longitudinal axis of the punching beam and thus parallel to a conveying direction of the plastic film or the plastic film composite material.
  • the crossbeam is made of at least three shell elements, whereby the outer shell elements are connected to the framework and whereby the middle shell element carries the punching beam and is suspended from the pendulum joint.
  • the crossbeam is compact.
  • Three shell elements of the same design can lie congruently on top of each other, the two outer shell elements are fixedly connected to the framework, they hold the middle shell element between them via the pendulum joint. The middle shell element can therefore swing freely between the two outer shell elements, whereby the middle shell element carries the punching beam.
  • the device in Figure 1 has a machine frame 1 that supports several work stations. 2 designates a deep-drawing station.
  • containers 5 are formed into a surface element 4, in particular a film strip, unrolled from a roll 3.
  • the surface element 4 is transported further along arrow 6, for example filled with objects and guided to a sealing station 26.
  • the containers 5 are sealed in this sealing station 26 with a sealing film 7.
  • the containers 5 are then transported to a cutting station 8.
  • the containers 5 are cut with a rotating knife 9 parallel to the conveying direction of the surface element 4.
  • Cutting transversely to the conveying direction of the surface element 4 is carried out with a punching device 10.
  • Figure 2 shows a component of the punching device 10, namely the punching bar 11 of the punching tool. This extends over the entire width of the surface element 4, which is held in chains 12 at its longitudinal edges for its transport.
  • the Figure 2 The containers 5 shown are to be separated from one another transversely to the conveying direction (arrow 6) of the surface element 4 using the punching device 10. Punching takes place along a line 13.
  • Figure 3 shows the punching device 10 during a punching process.
  • a surface element 4 is punched, which is fed to the punching device 10 along the conveying direction marked with arrow 6.
  • the Figure 2 The punching beam 11 shown is accommodated in a frame 14.
  • a punching lower tool 15 is also accommodated in the frame 14.
  • FIGs 4 and 5 show that the shell element 19 is connected to the shell elements 18 and 18' via a pendulum joint 20.
  • the shell element 19 can swing within the two outer shell elements 18, 18', as shown by the double arrow 25 in Figure 5
  • the shell element 19 carries the punching beam 11.
  • Figures 4 and 6 show that the pendulum joint 20 has an eccentric section, which allows a change in the height of the shell element 19 relative to the shell elements 18, 18'.
  • On the A disk 21 is arranged in the eccentric section of the pendulum joint 20. This is accommodated in the middle shell element 19. Height adjustments can be made via knurled sections 22, a fixing element 23 corresponds to a row of holes 24. The rotational position of the pendulum joint 20 can be determined using the fixing element 23.
  • FIGs 7 and 8 show an alternative embodiment of the shell element 19.
  • the shell element 19 is again connected to the shell elements 18 and 18' via the pendulum joint 20, but an alternative mechanism for changing the height of the shell element 19 is designed.
  • This alternative mechanism comprises a wedge-shaped frame 26a, which is arranged obliquely to the horizontal.
  • the frame 26a is assigned a spindle drive 27, which is attached to the frame 26a.
  • Figure 8 directly shows the shell element 19.
  • Figure 9 shows that the spindle drive 27 is guided outwards within the shell element 19 to a handle 28.
  • a further handle 29 is also provided, which serves to clamp the spindle drive 27.
  • Figure 8 shows that the wedge-shaped frame 26a has its wedge shape within a frame cutout, i.e. on the inside of the frame 26a. Moving this frame 26a causes a change in the height of the arrangement of the shell element 19.
