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.

1 . A tray sealer comprising:
 a conveyor for conveying trays to a work station of the tray sealer in a conveying direction, said conveyor comprising at least two conveyor belts;   wherein at least one of said conveyer belts being displaceable in a direction transverse to the conveying direction.   
     
     
         2 . The tray sealer of  claim 1 , wherein said conveyor includes a supply conveyor and a collecting conveyor disposed downstream of the supply conveyor, said supply conveyor and said collecting conveyor each including at least two said conveyor belts at least one of which is displaceable in a direction transverse to the conveying direction. 
     
     
         3 . The tray sealer of  claim 1 , wherein all the conveyor belts are adapted to be displaced in a direction transverse to the conveying direction. 
     
     
         4 . The tray sealer of  claim 1 , wherein the conveyor belts are adapted to be driven in a form-fit manner. 
     
     
         5 . The tray sealer of  claim 1 , wherein the conveyor belts are toothed belts used for conveying the trays. 
     
     
         6 . The tray sealer of  claim 5 , wherein the toothed belts have teeth on either side thereof 
     
     
         7 . The tray sealer of  claim 6 , wherein the toothed belts are adapted to be driven via the teeth. 
     
     
         8 . The tray sealer of  claim 6 , wherein the teeth of the toothed belts are round in shape. 
     
     
         9 . The tray sealer of  claim 1 , wherein the conveyor belts each have a width of 40 mm or less. 
     
     
         10 . The tray sealer of  claim 1 , wherein the conveyor belts each have a width of 20 mm or less. 
     
     
         11 . The tray sealer of  claim 2 , wherein at least one conveyor belt of the supply conveyor and at least one conveyor belt of the collecting conveyor have, in the conveying direction, a common conveying path in the area where the trays are transferred from the supply conveyor to the collecting conveyor. 
     
     
         12 . The tray sealer of  claim 1 , wherein the conveyor belts can be displaced manually, pneumatically or by an electric motor. 
     
     
         13 . The tray sealer of  claim 2 , wherein the respective conveyor belts of the supply conveyor and of the collecting conveyor have a common drive shaft for driving the respective conveyor belts.
