Benefits of technology

The present invention is a tray sealer which has a suppler conveyor and a collector conveyor both with at least two conveyor belts that are transversely displaceable. The narrow conveyor belts improve process reliability and allow for higher belt speeds and accelerations. The toothed belts with a round shape prevent product residues from depositing and are easier to clean. The conveyor belts have a common drive shaft which simplifies the structural design and reduces costs. The technical effects of this invention are improved production efficiency and process reliability.

Problems solved by technology

The adherence may also change during the production process due to an increase in air humidity or due to liquid product residues, and this leads to malpositioning on the collecting belt.
These downtimes impair the performance of the tray sealer.

Abstract

The invention relates to a tray sealer comprising conveyor belts that can be displaced in a direction transversely to the conveying direction.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This Application claims priority to German Application Number 102011106826.4 filed Jul. 7, 2011 to Wolfgang Negele entitled “Tray Sealer,” currently pending, the entire disclosure of which is incorporated herein by reference.FIELD OF INVENTION[0002]The invention relates generally to a tray sealer.BACKGROUND[0003]Tray sealers of the type offered also by the applicant are disclosed in DE 10 2008 030 510 A1. In order to achieve high performance, belt speeds and belt accelerations can be varied by the operator making use of the machine control. In regards to high belt speeds and belt accelerations, it is of decisive importance that the bottom of the tray filled with a product adheres to the belt surface of the conveyor. The adherence may also change during the production process due to an increase in air humidity or due to liquid product residues, and this leads to malpositioning on the collecting belt. A gripper system may then perhaps no lon...
