Definitions

  • the invention relates to a film handling arrangement for packaging machines, in particular for Straffbanderoliermaschinen, with a film roll and a dancer system as a storage and force limiters.
  • the object of the invention is to propose a device which makes it possible to minimize the web forces in the film when inserting the goods in the film curtain to ensure a uniform banding and avoid problems when welding the film and thus to drive the highest clock rates.
  • the trigger device is designed as a driven take-off roller, which can cooperate with a pressure roller.
  • the extraction device is equipped with a stepping motor, servomotor or the like.
  • Another very advantageous embodiment of the invention is also present when the dancer system has a sequence of fixed and movable pulleys, which are controlled, spring-loaded or inertially effective.
  • the dancer system creates a supply of material that allows for even extraction.
  • the second dancer system should be small and have low inertia.
  • the film brake ensures a controlled unwinding of the film and thus also determines the tightening of the container.
  • Another very advantageous development of the invention is also present if two film handling arrangements are provided, wherein one is provided for a top film, the other for a bottom film.
  • the film handling arrangement can be easily adapted to the respective requirements.
  • a very advantageous packaging machine according to the invention with a film handling arrangement according to the invention is provided when the film handling arrangement is provided for clamping a film curtain of lower and upper film in a strapping machine.
  • An inventively very advantageous method for operating a packaging machine is when a curtain of lower and upper film is clamped, wherein the two films by a weld are interconnected, the goods to be packaged, usually even packaging, which are put together to form a multi-piece packaging, pushed into the unfolded film curtain and welded to the goods upper and lower film under tension with each other, and the packaged goods are separated from the Folienzu interviewn.
  • top and / or bottom foil are pulled taut over the take-off roll before welding.
  • Another very advantageous embodiment of the invention is also present when the banding is adjustable to a wide variety of container sizes and maximum cycle times.
  • the device and the method is universally applicable and increases the throughput over known devices.
  • FIG. 1 an arrangement for film handling for a banding machine referred.
  • a first reel 2 On a first reel 2 an upper film 3 is provided.
  • the bobbin is prevented by a brake 4 on a too light and automatic unwinding.
  • the upper film 3 is guided over a dancer system 5, which consists of fixed rollers 6 and arranged on a rocker 7 movable rollers 8.
  • This dancer system 5 serves as a film store that can provide film material for processing very quickly if required.
  • the dancer system 5 serves as an attenuator, so that the film replenishment occurs smoothly.
  • the dancer system 5 can control the roller brake 4.
  • the dancer system 5 is followed by a discharge device 9.
  • This discharge device 9 consists of a driven by a servo motor take-off roller 10 and a pressure roller 11, which ensures that the top film does not slip on the take-off roll 10. It is also conceivable that the pressure roller 11 is also designed to be driven.
  • a second reel 22 which provides a lower foil 23.
  • the bobbin 22 is equipped with a brake 24.
  • the lower film 23 is passed through a dancer system 25, which consists of fixed rollers 26 and arranged on a rocker 27 rollers 28. Also this dancer system 25 serves as a film storage.
  • a second removal device for the lower film 23 has been dispensed with.
  • a second removal device is provided, which in turn consists of a take-off roll and a pressure roller.
  • Lower film 23 and upper film 3 are connected to each other via a weld 12.
  • the weld 12 is arranged in the region of the insertion level for a plurality of packages 13 to be joined together by a taut banderole.
  • the exact position of the seam 12 can be displaced by a corresponding advance or retraction of the removal device 9 or the withdrawal devices, so that this is arranged at the respective desired location of the band to be formed.
  • the packages are, for example, summarized by a stacker and then pushed against the curtain formed by the upper film 3 and lower film 23.
  • the upper film 3 is connected to the lower film 23 by means of a welding device 13.
  • the formed band 14 is separated from the upper film 3 and the lower film 23, and upper film 3 and lower film 23 are again joined together so that they form a new film curtain for forming the next band.
  • the defined tensioning of the films not only prevents unwanted deformation of the films. It also prevents wrinkles.
  • the removal devices are adapted to the packaging process, ie the insertion and transport of the packaging, so that a harmonious packaging process results in which the force on the films and the seam 12 is minimized.
  • the reproducibility of the banding process is also improved.
  • the banding is very uniform for the same packaging at a very high clock rate.
  • the brake 24 is dispensed with for the lower film. Alone the inertia of the film delivery is usually sufficient.
