Definitions

  • the invention relates to a thermoforming machine according to the preamble of claim 1 and to a method having the features of claim 11.
  • Rotary punches are known for cutting, punching or scoring a film web between a cutting roll and a counter roll.
  • the WO 2013/134495 A1 discloses a tray sealing machine having a rotary cutter for cutting lid sheet sections which are sealed onto trays to produce packages.
  • the object of the invention is to provide a thermoforming machine with a rotary cutting device for cutting sealed containers.

  • the thermoforming machine according to the invention is characterized in that the cutting station has a rotary cutting device with a cutting cylinder and a counter-cylinder.
  • One advantage is the smaller space requirement of such a cutting station over known complete cutting stations.
  • Another advantage is the reduction of film waste or the lower film consumption, especially for small portion packs, as with a rotary cutter smaller distances between adjacent packages are possible than with the known complete cutting stations. For example, distances of 4 to 5 mm can be reduced to half in complete cutting stations.
  • thermoforming machine may include a sealing station configured to seal the containers with a second sheet material.
  • the thermoforming machine becomes a thermoforming packaging machine.

It may also happen that the end position of the film feed due to inertia, wear of the staple chains or other negative influences on the film feed system are different and thus also the different position of the printed image of the lower film. These tolerances can also be compensated.
  • the cutting cylinder is designed for waste-free cutting between at least two adjacent packing flanges in the direction of production in order to minimize the film consumption.
  • the cutting cylinder is driven continuously, intermittently and / or reversibly, so that even after a film feed tolerances can be compensated, in which the cutting cylinder has to be moved counter to the production direction.
  • the cutting station preferably has a squeezing device, for example in the form of a roller, so as not to completely cut packages, but to perforate such that they still get caught on the film composite or on the sub-film web until the squeezing device separates the packages from the film composite or the sub-film web ,

  • the cutting cylinder may have a magnetic surface on which a cutting plate can be applied.
  • the length of the cutting plate or the cutting edges can have a division or length which is different from the take-off lengths of the film feed.
  • the movement of the cutting cylinder may be adjusted by means of the control of the movement of the film feed so that this difference can be dynamically balanced for each package or format during the movement of the cutting cylinder and the film advance.
  • the controller may include an adjustable electronic gear factor to synchronize the film transport with the rotary cutter.
  • an adjustable electronic gear factor to synchronize the film transport with the rotary cutter.
  • the rotary cutting device comprises a reference sensor which detects each revolution of the cutting cylinder. This is particularly advantageous in a calculation or determination of the electronic transmission factor.
  • the reference sensor By means of the reference sensor, the cutting cylinder or its servo drive can also be referenced at the start of the machine.
  • a method of operating a thermoforming machine comprises forming containers into a first web-like material through a forming station. It is characterized by cutting or perforating the sheet-like materials between the containers after forming the containers by a rotary cutter.
  • the method may also include sealing the containers with a second sheet material through a sealing station.
  • the sealing can z. B. take place before cutting or perforating by the rotary cutter.
