Abstract

The invention relates to a device for dereeling a film web roll which is mounted on a rotating shaft, whereby the shaft (2) comprises a brake disk (3) which co-operates with brake blocks.

Description

Folienabwicklung mit ScheibenbremseFilm processing with disc brake
Die vorliegende Erfindung betrifft eine Vorrichtung zum Abwickeln einer Folienbahnrolle, die auf einer drehbaren Welle gelagert ist.The present invention relates to a device for unwinding a film web roll, which is mounted on a rotatable shaft.
Lebensmittel werden heutzutage immer öfter in Kunststorrverpackungen angeboten. Diese Kunststoff erpackungen bestehen in der Regel aus einer tiefgezogenen Verpackungsmulde und einer Deckelfolie, die nach der Befüllung der Verpackungsmulde auf diese gesiegelt wird. Die Herstellung der tiefgezogenen Verpackungsmulden und deren Verschluß mit der Deckelfolie erfolgt taktweise, so dass die Kunststoffolie, aus der die Verpackungsmulden hergestellt wird, und die Deckelfolie taktweise von einer drehbar gelagerten Rolle abgezogen werden. Um zu vermeiden, dass die Verpackungsfolie während des Herstellverfahrens durchhängt, muß die Rolle abgebremst werden.Nowadays, food is increasingly being offered in plastic packaging. These plastic packs 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. To prevent the packaging film from sagging during the manufacturing process, the roll must be braked.
Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde eine Vorrichtung zum Abwickeln einer Folienbahnrolle zur Verfügung zu stellen.The present invention is therefore based on the object of providing a device for unwinding a film web roll.
Gelöst wird die Aufgabe erfϊndungsgemäß durch Vorrichtung zum Abwickeln einer Folienbahnrolle, die auf einer drehbaren Welle gelagert ist, und die eine Bremsscheibe aufweist, die mit Bremsbacken zusammenwirkt.According to the invention, 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.
Es war für den Fachmann überaus erstaunlich, dass es mit der erfindungsgemäßen Vorrichtung gelingt wesentlich höhere Bremskräfte zu realisieren, so dass die Folienrollen schneller und/oder größere Folienrollen abgebremst werden können.It was extremely surprising for the person skilled in the art that 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.
Im Folgenden wird die erfindungsgemäße Vorrichtung anhand von Figur 1 erläutert. Diese Erläuterungen sind lediglich beispielhaft und schränken den allgemeinen Erfindungsgedanken nicht ein.The device according to the invention is explained below with reference to FIG. 1. These explanations are only examples and do not limit the general inventive concept.
Figur 1 zeigt die erfindungsgemäße Vorrichtung. Eine Rolle 1 ist auf einer drehbaren Welle 2 drehfest gelagert. Die Welle 2 ist an ihrer rechten Seite an der Wandung einer Verpackungsmaschine gelagert. An die drehbare Welle 2 ist eine Bremsscheibe 3 angeschraubt, die mit Bremsbacken 4 zusammenwirken. Die Bremsbacken, die in dem vorliegenden Fall pneumatisch betrieben werden, können so eingestellt werden, dass die Drehung der Folienrolle permanent verzögert oder vollständig gestoppt wird. Die Bremsbacken sind mit der Wandung der Verpackungsmaschine verbunden. Die erfindungsgemäße Vorrichtung eignet sich sowohl für die Abwicklung der Deckelfolie als auch für die Folie aus der die Verpackungsmulde gefertigt wird.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.
Vorzugsweise ist die Welle 2, die daran befestigte Bremsscheibe 3 und die Bremsbacken 4 schwimmend d.h. vertikal und quer zur Laufrichtung der jeweiligen Folie verschieblich in der Wandung 5 gelagert. Diese Ausführungsform der vorliegenden Erfindung hat den Vorteil, dass auch Folierollen verarbeitet werden können, die nicht völlig gleichmäßig aufgerollt sind.Preferably, 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.
Die erfindungsgemäße Vorrichtung ist einfach und kostengünstig herzustellen. Mit der erfindungsgemäßen Vorrichtung können dreimal höhere Bremskräfte erzielt werden als dies von Folienrollenbremsen gemäß dem Stand der Technik bekannt ist. Vorzugsweise findet die erfindungsgemäße Vorrichtung Anwendung bei Verpackungsmaschinen. 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.
