Definitions

  • the invention relates to a thermoforming system, and in particular a device for transferring Blister strips in a downstream cartoning machine in the thermoforming line.
  • Thermoforming lines are flawless blister strips that are in the hereinafter referred to as "Gutblisterstsammlung" from a first gripping device equipped with suction devices taken from a removal shaft, and a linear one Blister transport route fed, which in turn into a Conveying device of the cartoning machine opens.
  • faulty Blister strips are removed from the Removal shaft by means of the first gripping device ejected a bad parts chute.
  • a refill with one second gripping device arranged according to the defective blister strips Takes replacement blister strips and the Blister transport line feeds.
  • the well-known Thermoforming system is through the second gripping device and the linear blister transport route is relatively complex built up and takes up a lot of space.
  • thermoforming system according to the invention with the features of Claim 1 has the advantage that it is special is compact and is relatively simple because it no blister transport route and only one Gripping device required. In addition, the Device particularly powerful.
  • Figure 1 shows part of a Thermoforming plant in a side view
  • the figure 2 a suction cup removal system in a side view.
  • the device 10 shown in FIG. 1 is Part of a thermoforming system, and is used for transfer from blister strips to a continuously working Conveyor 11 of a downstream, not shown cartoning machine.
  • the device 10 has blister strips continuously working suction cup system 12, which consists of a two-stage, four-section epicyclic gear and two connected to a vacuum source, not shown Suction heads 13 exists.
  • the epicyclic gear is such trained that the suction heads 13 each on a Orbital trajectory consisting of one hypocycloid with three There are curve sections.
  • a discharge shaft 16 for faulty Blister For transferring faulty blister strips is the discharge shaft 16 a separation device 18 assigned.
  • the separating device 18 consists of one on the opposite of the punching device 15 Side of the sucker removal system 12 arranged in one Axis 19 pivotally mounted rocker 20, at the tip a fork 21 is attached. Above the Suction cup removal system 12 and the separating device 18 is also a refill 23 with replacement blister strips arranged.
  • the arrangement of the refill shaft 23 is such that this is above the range of one second turning point of the movement path of the suction heads 13 located.
  • a filing point 25 closes Good blister strips on.
  • a second rocker 26 rotatably mounted, the arm 27 in Active connection is arranged with the storage location 25, and those for pushing good blister strips into one itself the storage location 25 immediately following Stacking device 30 is used.
  • Thrust device 31 arranged, the two continuously rotating fingers 33 for sliding over one strip of good blister between each of the walls 34, 35 a cell 36 of the conveyor 11.
  • the suction cup removal system shown in more detail in FIG. 2 12 each shows by means of two double rockers 37 guided suction heads 13, one in the planet center 38 stored cam 39 revolve. Two different ones Paths of movement of the suction heads 13 can be realized the cam 39 is rotatable. With not twisted cam 39, the suction head 13 on his Movement path in the area of the refill shaft 23 by one certain distance drawn to the planet center 38, see above that the suction head 13 including the blister strips below the Refill shaft 23 is passed. To record a replacement blister strip from the refill slot 23 the cam 39 on the way of the suction head 13 from the punching device 15 to the refill shaft 23 by one certain angle rotated so that the suction head 13 in the area of the refill shaft 23 in operative connection with one there provided replacement blister strips. On the further path of the suction head 13 from the refill shaft 23 to discard 25, cam 39 is in again turned back to its original position.
  • the twisting the cam plate 39 is preferably carried out with the aid of a Pneumatic cylinder 41 and a belt drive 42.
  • the above-described device 10 for transferring Blister strips works as follows: Not using shown sensors and devices with the Control device of the device 10 are connected faulty blister strips or good blister strips recognized. In the presence of a good blister strip the punching device 15 takes over a suction head 13 of the Sucker removal system 12 the relevant GutblisterstMail, leads this below the Refill 23 past what is described as above achieved a corresponding position of the cam 39 is, and puts it at the deposit 25.
  • the filed GutblisterstMail is captured by the arm 27, and into the Stacking device 30 pushed over. As soon as the GutblisterstMail located in the stacking device 30, it is held by a finger 33 of the pushing device 31 captured him between the walls 34, 35 of the Pushes conveyor 11.
  • the punching device 15 becomes the relevant one Blister strips first pulled off a suction head 13, whereupon the rocker 26 is pivoted in the axis 19 to the faulty blister strips by means of their fork 21 from to take over the suction head 13, and in the Transfer shaft 16 to transfer.
  • the suction head 13 to the refill 23 is the Cam 39 rotated such that the suction head 13 in Area of the refill shaft 23 in operative connection with a replacement blister strip provided, which is subtracted from the suction head 13.
  • the cam 39 is in again turned back to its original position so that the Replacement blister strips deposited at the deposit point 25 can be. The rest of the process is the same as for a strip of good blister.
  • the device 10 also Gut blister strips inserted into the refill shaft 23 can be. Manual loading of the Refill slot 23 with spare blister strips.
