ABSTRACT:

PRIOR ART
The invention relates to a conveyor device as has been disclosed, for example, by DE 40 36 510 A1. The known conveyor device, which is used to transport collapsible boxes contained between drivers, has a number of conveyor chains disposed parallel to one another, which respectively wind around gear-shaped deflecting wheels. Because of the deflecting wheels, the chain links of the conveyor chains are not permitted to exceed a particular length so that they can be reliably guided by the teeth of the deflecting wheels. Furthermore, guide rails are provided as a support for the erected collapsible boxes; the collapsible boxes slide along these guide rails and the drivers of the conveyor chains protrude between these rails. The guide rails are necessary since due to the danger of contamination or damage, the erected collapsible boxes cannot rest directly on the conveyor chains. The structural cost of the known conveyor device is relatively high as a result of the guide rails. Furthermore, small collapsible box formats are particularly difficult to manipulate due to the friction between the collapsible boxes and the guide rails.
ADVANTAGES OF THE INVENTION
The conveyor device according to the invention, has the advantage over the prior art that objects can be conveyed directly on the chain elements and therefore in a frictionless manner. Consequently, even small collapsible box formats are easy to manipulate. Furthermore, no additional guide rails or the like are required. Therefore in addition, the structural cost of the conveyor device is relatively low.
Other advantages and advantageous improvements of the conveyor device according to the invention ensue from the drawings claims and the specification.
