Definitions

  • the invention relates to a workstation integrated in a packaging machine, having an upper part and a lower part, which can be lowered into a lowered position or lifted into a raised position, and a lifting device for carrying out the movement.
  • Such a workstation is used in a known manner as part of packaging machines and in particular of vacuum packaging machines. Because of the forces occurring during operation, the known workstations are very heavy.
  • a workstation for a packaging machine is known in accordance with Fig. 4 an upper part and a lower part are each movable relative to each other via a toggle joint.
  • the drive of the two toggle joints is done together via a shaft connected to these.
  • a cutting station of a packaging machine is known according to FIG. 16, in which a pressure plate forming an upper part can be moved relative to a cutting drum forming a fixed lower part.
  • a lifting device for carrying out the movement which comprises a pair of parallel aligned guide rods which are fixedly connected at its upper end to the upper part and at its lower end fixed to a yoke.
  • the guide rods are slidably moved with the associated upper part via a toggle lever system in guide bushes connected to the lower part.
  • the GB-A 804352 shows a press in which a lower part is moved against an upper part via a Kniehebelsysytem.
  • the object of the invention is to provide a workstation of the type described above, which is used for comparable purposes and in particular also in vacuum packaging machines, which is constructed considerably lighter and compact, which has a particularly easily adjustable lifting device for the lower part and which is constructed in that it can be moved within the packaging machine.
  • the workstation has the advantage that it is space-saving and easy to build and that the lifting device for the lower part is due to the leadership of the lower part relative to the upper part exactly and easily adjustable.
  • the packaging machine shown comprises a trained as a thermoforming station first workstation 1, designed as an evacuation and sealing station second workstation 2 and designed as a cutting station third workstation 3.
  • the three workstations are supported by a machine frame 4, at the same time the guide for a chain drive, not shown for conveying the packaging material 5 or the packaging container to be formed therefrom.
  • the workstation has an upper part 6 and a cooperating lower part 7, which serve in the case of thermoforming station in the merged state by applying corresponding pressure differences in the interior for deep drawing of containers 8 from the packaging material 5 formed from films.
  • the workstation has a substantially rectangular configuration in its plan view.
  • the upper part is supported at its four corners by four guide rods 9, 10, 11.
  • the upper part in its four corners in the vertical direction Vietnameserekkende and mutually parallel bores, which are dimensioned with respect to their dimension and designed with respect to their surface so that the upper part on the guide rods 9, 10, 11 can slide.
  • There are provided for adjustable connection of the upper part with the guide rods screws 12, 13, 14, by adjusting the upper part is adjustable in a small area on the guide rods down.
  • pivot bearings 15, 16, 17 are firmly connected by friction welding to pivot bearings 15, 16, 17.
  • a pair of associated left and right pivot bearings 15, 16 are connected by a yoke 18 each.
  • the respectively associated rotary bearings 16, 17 are connected to one another via a lifting shaft 19.
  • the length dimensions of the yoke 18 and lifting shaft 19 are dimensioned so that the associated four guide rods are aligned parallel to each other.
  • the lift shafts are best Fig. 2 it can be seen a rectangular cross-section and have at their end faces at one end of the rectangular cross-section bearing journals with which they are mounted in the pivot bearings.
  • the work station of the lower part 7 comprises the actual cooperating with the upper part of the chamber part 20 and a supporting this bottom part 21.
  • the bottom part has at the guide rods corresponding locations guide bushings 22, 23, as best of Fig. 4 is apparent
  • pairs of toggle levers 24, 25 are provided on two opposite sides of the workstation. These have as lower with the pivot bearings 15, 16, 17 connected leg, which are formed by the respective lifting shaft 19.
  • the end of the rectangular shaft opposite from the bearing pin is connected via a pivot connection 26, 27 to an upper leg 28, 29 at one of its ends, which is connected at its opposite free end to the bottom part 21 via a rotary connection.
  • the connection point between the legs 28, 29 and the bottom part 21 is in the vertical direction directly above the respective bearing of the lifting shaft 19th
  • a parallel bar 30 is connected in a rotationally fixed manner via two equal-length legs 31, 32 to the pivots of the lifting shafts 19 or the lifting shafts in the manner of a parallelogram.
  • the fulcrums are such that there is a parallelogram construction.
  • a pneumatically or hydraulically driven piston-cylinder device 33 is provided, which is fastened with its one end to the yoke 18 and engages with the free end of its piston rod on the parallel rod 30.
  • the piston-cylinder device is arranged such that the lower part 7 in the retracted position of the piston 34 of the piston-cylinder device is the toggle joint in its folded position and thus the lower part in its lowered position.
  • the toggle joint In the extended position of the piston 34, the toggle joint is in his in Fig. 3 shown extended position and thus the lower part in the upper position in which the chamber is closed.
  • the toggle joint must carry the maximum force. This is possible in spite of the lifting shaft 19 formed only from a rectangular material, because the rectangular profile is aligned here in the vertical direction and reaches the highest rigidity in the working position.
  • a pneumatically actuated large-area membrane device 35 is provided, which is acted upon via a pneumatic line 36.
  • a default setting via the screws 12, 13, 14 for the position of the upper part. It is then moves the lower part in the manner described above relative to the upper part in the closed position.
  • the membrane 35 is subjected to compressed air, whereby an additional contact force is exerted.
