Benefits of technology

The present invention is a thermo-forming packaging machine that can join a formed tray and a formed top together as precisely as possible in a sealing station. The technical effect of this invention is the ability to create a more robust and secure packaging solution.

Problems solved by technology

It is particularly difficult in a thermo-forming packaging machine, which in addition to the forming station for a base film comprises a forming station for a top film and where both film webs comprise an imprint and a print mark, to unite and to seal the forming of the two film webs in the sealing station accurately in their desired position relative to each other.

Abstract

The invention relates to a thermo-forming packaging machine with a controller, a first forming station for forming a tray into a base film and a second motor-adjustable forming station for forming a lid into a top film. A first detection device detects the marking of the base film for controlling a film advance step of the tray associated with this marking into the sealing station.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This Application claims priority to European Patent Application Number 13187888.6 filed Oct. 9, 2013, to Elmar Ehrmann entitled “Thermo-Forming Packaging Machine and Method,” currently pending, the entire disclosure of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The invention relates to a thermo-forming packaging machine and to a method for operating a thermo-forming packaging machine.BACKGROUND OF THE INVENTION[0003]A thermo-forming packaging machine is known from EP 0 569 993 A1 having a print mark sensor for detecting a print mark of a base film. The print mark sensor is mounted upstream of a forming station and transmits data to a controller which positions work stations such as a forming station, a sealing station and / or a cutting station corresponding to the distance between two successive print marks.[0004]A thermo-forming packaging machine is known from DE 2437127 A1 having a print mark sensor for detecti...
