Definitions
- the present invention relates to a device for unwinding a film web roll, which is mounted on a rotatable shaft.
- plastic packaging usually consist of a deep-drawn packaging tray and a cover film that is sealed onto the packaging tray after it has been filled.
- the deep-drawn packaging troughs are produced and their closure with the cover film is carried out in cycles, so that the plastic film from which the packaging troughs are produced and the cover film are removed in cycles from a rotatably mounted roll.
- the roll must be braked.
- the present invention is therefore based on the object of providing a device for unwinding a film web roll.
- the object is achieved by a device for unwinding a film web roll, which is mounted on a rotatable shaft and which has a brake disk which interacts with brake shoes.
- the device according to the invention succeeds in realizing significantly higher braking forces, so that the film rolls can be braked faster and / or larger film rolls.
- Figure 1 shows the device according to the invention.
- a roller 1 is rotatably mounted on a rotatable shaft 2.
- the shaft 2 is supported on its right side on the wall of a packaging machine.
- a brake disc 3 is screwed onto the rotatable shaft 2 and cooperates with brake shoes 4.
- the Brake shoes which are operated pneumatically in the present case, can be set so that the rotation of the film roll is permanently delayed or stopped completely.
- the brake shoes are connected to the wall of the packaging machine.
- the device according to the invention is suitable both for handling the cover film and for the film from which the packaging tray is made.
- the shaft 2, the brake disc 3 attached to it and the brake shoes 4 are floating i.e. vertically and transversely to the direction of the respective film slidably mounted in the wall 5.
- This embodiment of the present invention has the advantage that film rolls that are not rolled up completely uniformly can also be processed.
- the device according to the invention is simple and inexpensive to manufacture. With the device according to the invention three times higher braking forces can be achieved than is known from film roller brakes according to the prior art.
- the device according to the invention is preferably used in packaging machines.
