Definitions

  • thermoforming system becomes a packaging material web with bowls by means of a feed roller from one cycle Perforating device conveyed to a punching device, the individual blister strips from the packaging material web punched out.
  • the perforating device is horizontal, and the Punching device vertical and below with respect to the Perforating device arranged. Because each one below of the two drive boxes located Facilities require a certain amount of space is a relatively large distance from between the two Facilities arranged preferred roller required.
  • the large adjustment range is special required after a break in production if due to complete cooling of the packaging material web a large Has shrink length.
  • thermoforming system is the required adjustment range by a positionable perforating device guaranteed.
  • thermoforming system according to the invention with the characteristic features of claim 1 has in contrast the advantage that the arrangement of the perforating / embossing device the distances to the punching device Packaging material web between the perforating / embossing device and the punching device can be shortened. This is only one small adjustment range to compensate for the shrink length the packaging material web required to the tolerances between the perforation / embossing and the punch contour ensure. This small adjustment range can be through a position-changing design of the feed roller simply realize so that the construction of the Thereby simplified thermoforming system according to the invention is particularly compact that both the perforating / embossing device as well as the punching device stationary are arranged.
  • 10 denotes a blister sheet which from a bowl 1 having a sub-web and one on it sealed cover sheet consists.
  • the bowls 1 are by means of an upstream, not shown Filling device for pharmaceutical products such as tablets, Coated tablets or similar brought in.
  • the blister track designed in this way 10 arrives in the area of a stationary one Perforating / embossing device 11, which consists of an upper part 12 and a lower part 13 that can be moved against it.
  • Perforating / embossing device 11 which consists of an upper part 12 and a lower part 13 that can be moved against it.
  • Perforating / embossing knives 14 in the Upper part 12 are perforating / embossing knives 14, and in Lower part 13 with the perforating / embossing knives 14 interacting perforating / embossing die 16 arranged.
  • the drive box 15 of the perforating / embossing device 11 arranged below the lower part 12 facing the cups 1 . Closes the perforating / embossing device 11 a cyclically driven feed roller 17.
  • the Shell surface 18 of the preferred roller 17 are in the preferred direction the blister web 10 viewed side by side and one behind the other Recesses 19 formed to advance the Interact the blister strip 10 with the wells 1.
  • X is the distance between the center of the perforating / embossing device 11 to the middle of those first Recesses 19 in the preferred roller 17 referred to as first for pulling the blister sheet 10 into engagement with the corresponding bowls 1 are.
  • the perforating / embossing device 11 is preferred not horizontally, but at an angle ⁇ of about eight Degree is inclined to the horizontal, so that the Drive box 15 points away from the preferred roller 17.
  • thermoforming system In order to compensate for any shrink lengths that occur Blister web 10, for example after a production break the thermoforming system to adjust the distances X and Y, thus the tolerances between the perforation and the The punching pattern of the blister strips is adhered to Preferred roller 17 is arranged adjustable. The adjustment of the Preferred roller 17 takes place along an approximately 45 degrees Horizontal inclined axis 26. Now the Preferred roller 17 away from the two drive boxes 15, 25 adjusted, both distances increase accordingly X, Y at the same time.
  • the distances X, Y between the Preferred roller 17 and the perforating / embossing device 11 or the punching device 23 from the start as low as should be chosen possible, that means that the just do not touch the two drive boxes 15, 25, and that the transport of the blister web 10 through the Preferred roller 17 is always ensured.
  • the two drive boxes 15, 25 can be replaced by a common drive box in which the drives of both the perforating / embossing device 11 and the punching device 23 are also arranged. Even at a common drive box is due to the inclination one of the two facilities possible additional space to create for the drives so that the distances X and Y can be minimized.
