Definitions

  • the invention is based on a thermoforming system according to the preamble of claim 1.
  • a packaging material web having cups is conveyed cyclically by means of a feed roller from a perforating device to a punching device which punches out individual blister strips from the packaging material web.
  • the perforating device is horizontal and the punching device is arranged vertically and below with respect to the perforating device. Since the drive boxes of the devices located below the two devices each require a certain amount of space, a relatively large distance from the feed roller arranged between the two devices is required.
  • the relatively large distance between the two devices has the consequence that, in order to compensate for the shrinking length of the packaging material web on its way from the perforating device to the punching device, a large adjustment range of at least one of the two devices is necessary so that the tolerances of the perforation to the punching contour can be maintained.
  • the large adjustment range is special after a break in production, if the packaging material web has a large shrink length due to the complete cooling. In the known thermoforming system, the required adjustment range is ensured by a perforating device that can change its position.
  • thermoforming system according to the invention with the characterizing features of claim 1 has the advantage that the distances of the packaging material web between the perforating / embossing device and the punching device are shortened by the arrangement of the perforating / embossing device for the punching device.
  • a small adjustment range is required to compensate for the shrinking length of the packaging material web in order to ensure the tolerances between the perforation / embossing and the punching contour.
  • This small adjustment range can be easily achieved by changing the position of the feed roller, so that the structure of the thermoforming system according to the invention is simplified and particularly compact in that both the perforating / embossing device and the punching device are arranged in a stationary manner.
  • thermoforming system According to the invention,
  • FIG. 1 shows part of a thermoforming system in a simplified side view.
  • 10 denotes a blister web, which consists of a bottom web having cups 1 and a cover film web sealed thereon.
  • Pharmaceutical products such as tablets, coated tablets or the like are inserted into the cups 1 by means of an upstream filling device (not shown). brought in.
  • the blister web 10 formed in this way reaches the area of a stationary perforating / embossing device 11, which consists of an upper part 12 and a lower part 13 which can be moved against it.
  • Perforating / embossing knives 14 are arranged in the upper part 12, and a perforating / embossing die 16 cooperating with the perforating / embossing knives 14 is arranged in the lower part 13.
  • the drive box 15 of the perforating / embossing device 11 is arranged below the lower part 12 facing the cups 1.
  • the perforating / embossing device 11 is followed by a cyclically driven feed roller 17.
  • recesses 19 are formed side by side and one behind the other, viewed in the preferred direction of the blister web 10, which cooperate with the cups 1 to advance the blister web 10.
  • X denotes the distance between the center of the perforating / embossing device 11 to the center of those first recesses 19 in the feed roller 17 which are the first to pull the blister web 10 into engagement with the corresponding cups 1.
  • the perforating / embossing device 11 is not horizontal, but inclined by an angle ⁇ , which is approximately eight degrees, with respect to the horizontal, so that the drive box 15 points away from the feed roller 17.
  • a second drive box 25 of the punching device 23 assigned to the lower part 22 points in the direction of the drive box 15 of the perforating / embossing device 11, but without touching it.
  • Y denotes the distance from the last recesses 19 of the feed roller 17, which are in engagement with the cups 1, to the center of the punching device 23.
  • the feed roller 17 is arranged to be adjustable.
  • the adjustment roller 17 is adjusted along an axis 26 which is inclined approximately 45 degrees to the horizontal. If the adjustment roller 17 is now moved away from the two drive boxes 15, 25, then the two distances X, Y increase at the same time.
  • the distances X, Y between the feed roller 17 and the perforating / embossing device 11 or the punching device 23 should be chosen as small as possible from the outset, that is to say that the two drive boxes 15, 25 are just not yet touch, and that the transport of the blister 10 is always ensured by the preferential roller 17.
