Deep-drawing machine with rotation cutting device

Abstract

A deep-drawing machine having a forming station configured for forming containers into a first sheet-shaped material, and a cutting station disposed downstream of the forming station in a working direction. The cutting station is configured to cut or to perforate an area of the sheet-shaped materials disposed between the containers. The cutting station may include a rotation cutting device that comprises a cutting cylinder and an opposing cylinder. A method for operating a deep-drawing machine that comprises the following steps: forming containers into a first sheet-shaped material by a forming station, and cutting or perforating of the sheet-shaped materials in an area between the containers after forming of the containers using the rotation cutting device.

What is claimed is: 
     
         1 . A deep-drawing machine comprising:

         2 . The deep-drawing machine according to  claim 1 , further comprising a sealing station configured for sealing the containers with a second sheet-shaped material, wherein the cutting station is disposed downstream of the sealing station in the working direction. 
     
     
         3 . The deep-drawing machine according to  claim 1 , wherein the cutting cylinder and the opposing cylinder are drivingly engaged with one another using a gear drive. 
     
     
         4 . The deep-drawing machine according to  claim 3 , wherein the cutting cylinder and the opposing cylinder are driven by a servo motor. 
     
     
         5 . The deep-drawing machine according to  claim 1 , wherein the cutting cylinder and the opposing cylinder are each driven by a servo motor. 
     
     
         6 . The deep-drawing machine according to  claim 1 , further comprising a control for synchronizing the rotation of the cutting device and a film feeding device to one another for balancing one or more film feed tolerances. 
     
     
         7 . The deep-drawing machine according to  claim 1 , wherein the cutting cylinder provides waste-free cutting between two containers that are adjacent to each other in the working direction. 
     
     
         8 . The deep-drawing machine according to  claim 1 , wherein the cutting cylinder is driven one of continuously, intermittently, or reversibly. 
     
     
         9 . The deep-drawing machine according to  claim 1 , wherein the cutting station comprises an ejection device. 
     
     
         10 . The deep-drawing machine according to  claim 1 , wherein the rotation cutting device is configured to cut different formats of packages and packages having different draw-off lengths. 
     
     
         11 . The deep-drawing machine according to  claim 6 , wherein the control comprises an adjustable electronic transmission factor to synchronize the film feeding device with the rotation cutting device. 
     
     
         12 . The deep-drawing machine according to  claim 1 , wherein the rotation cutting device comprises a reference sensor that records every rotation of the cutting cylinder. 
     
     
         13 . A method for operating a deep-drawing machine comprising the steps of:
 forming a plurality of containers into a sheet-shaped material using a forming station;   one of cutting or perforating an area of the sheet-shaped materials disposed between the containers by a rotation cutting device after the forming the containers step.   
     
     
         14 . The method according to  claim 13 , further comprising the steps of:
 sealing the containers with a second sheet-shaped material by a sealing station, wherein the cutting or perforating step occurs after said sealing step.   
     
     
         15 . The method according to  claim 13 , further comprising the step of dynamically synchronizing the rotation cutting device and a film feeding device during a film feed movement. 
     
     
         16 . The method according to  claim 15 , wherein said dynamically synchronizing the rotation cutting device step is performed using an electronic transmission factor that is one of calculated or adjusted prior to each said film feed movement. 
     
     
         17 . The method according to  claim 15 , further comprising performing a balancing rotation by the rotation cutting device between two temporally adjacent said film feed movement when the film feeding device is standing still. 
     
     
         18 . The method according to  claim 15 , wherein the film feeding device stands still in concert with the rotation cutting device during an intermittent operation of the deep-drawing packaging machine.
