DESCRIPTION:
BRIEF SUMMARY
PRIOR ART
The invention relates to an apparatus for pushing bag packages or similar compliant articles into folding boxes. In the case of a known apparatus of this type, the packable-article cartons and the drivers for the folding boxes are arranged on endless conveying devices. For the pushing-in operation, use is made of pushers which can be moved parallel and transversely to the conveying direction of the packable-article cartons and of the folding boxes. In order to make it possible to push into folding boxes bag packages whose deformable cross-sectional area is partially larger than the cross section of the opening of the folding boxes, the pushers are assigned covering tongues which are coupled to a push rod such that they can be moved in the push-in direction independently of said pushers. During the pushing-in operation, the covering tongues first of all press the bag packages in the packable-article cartons downwards and then, after entering into the opening of the folding boxes, cause the upper wall of said folding boxes to bulge upwards.
The disadvantage with the known apparatus is that the introduction of force into the covering tongue takes place in the vicinity of its axis of rotation in the push rod, with the result that, due to the leverages, high forces are necessary in order to transmit, in particular, the desired pressing force for the bag package. This means that the apparatus is complex and expensive.
ADVANTAGES OF THE INVENTION
In contrast, the apparatus according to the invention has the advantage that the introduction of the pressing force, for compressing the bag package, into the covering tongue, takes place directly in the region of overlap between the covering tongue and the bag package by means of a contact-pressure member and a guide rail. Consequently, the necessary transmission forces in the covering tongue and its mount are reduced, as a result of which the apparatus is straightforward and inexpensive. Furthermore, a suitable arrangement of guide rails and supporting rollers makes it possible to achieve any desired pivot movement of the covering tongue. Consequently, the apparatus according to the invention can be adapted in a simple manner to various formats of bag packages and of folding boxes.
Further advantages of the apparatus according to the invention are given in the subclaims and the description hereinafter. The apparatus according to the invention can be particularly simply adapted to various formats of bag packages and of folding boxes if the guide rails are configured to be vertically adjustable. In order to increase the operational reliability of the apparatus according to the invention it is, furthermore, proposed to couple an overload sensor to the guide rail for compressing the bag package. The sensor detects if, for example, there are two bag packages in a packable-article carton instead of one or if a bag package has been wrongly inserted into the packable-article carton.
BRIEF DESCRIPTION OF THE DRAWINGS
An exemplary embodiment of the invention is represented in the drawings and is explained in more detail in the following description. FIGS. 1 to 3 show, in a simplified manner, cross sections of an apparatus for pushing bag packages or similar compliant articles into folding boxes during different operating phases.
DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENT
The apparatus for pushing bag packages 10 or similar compliant articles into folding boxes 12 has packable-article cartons 13 for receiving in each case one bag package 10, the latter being conveyed into the packable-article cartons 13 via conveying means (not shown) outside the apparatus. The packable-article cartons 13 are fastened on an endless conveyor, for example a chain conveyor 15. The cross-sectional areas of the packable-article cartons 13 are matched to the cross section of the opening of the folding boxes 12. A second chain conveyor 16 for the folding boxes 12 is arranged, parallel to the first chain conveyor 15, in the same plane in the apparatus. The chain conveyor 16 has
