DESCRIPTION:
BRIEF SUMMARY
PRIOR ART
The invention is based on a packaging machine in accordance with the preamble of claim 1. In such a packaging machine known, for example, from EP 0 465 437 A1, upright fold boxes which reveal an opening cross section are conveyed along a horizontal conveying path. Several blister strips, placed on top of each other and with a packing slip enclosing them in a U-shape, are respectively conveyed in a product bowl parallel and aligned with the fold boxes. The contents of the product bowls are pushed into the fold boxes by inserting slides associated with the product bowls and the fold boxes are subsequently closed. Packaging machines of this type are particularly suited for packing sturdy goods which completely fill the opening cross section. Fold boxes with an integrated support frame for packaging delicate objects, such as ampuls, vials and the like, now have become known from the German Utility Model Application G 93 04192.6, for example. The support frame is integrally connected with a wide interior wall of the folding box and, since it can be bent over flat against the interior wall, allows the flat transport and storage of such fold boxes. However, these fold boxes cannot be processed in the known packaging machine described above since, after putting the fold box upright, the support frame lies flat at least in part, and therefore the objects cannot be inserted into the receptacles for the object formed in the support frame.
It is therefore the object of the invention to disclose a packaging machine in which fold boxes with integrated support frames can also be processed.
ADVANTAGES OF THE INVENTION
In contrast to this, the packaging machine in accordance with the invention having the characterizing features of claim 1 has the advantage that fold boxes with integrated support frames can also be dependably processed.
Further advantages and advantageous embodiments ensue from the dependent claims and the specification. Dependable raising in connection with different support frame designs is achieved by means of the wedge-shaped design of the raising elements. The objects can be inserted into the support frame particularly well, if the latter is held by a support element during the insertion. Tilting of the objects during insertion can be prevented by a special embodiment of the inserting slides. Jamming of the support frame can be prevented by an appropriate embodiment of the raising elements.
DRAWINGS
An exemplary embodiment of the invention is represented in the drawings and will be explained in detail in the following description. FIG. 1 shows a section of the packaging machine in accordance with the invention in a simplified perspective view, FIG. 2 shows a fold box with an integrated support frame in a perspective view, FIGS. 3 to 5 represent cross sections through the packaging machine of FIG. 1 in different work phases, and FIG. 6 shows a cross section in accordance with FIG. 4 in an altered embodiment.
DESCRIPTION OF THE EXEMPLARY EMBODIMENT
A horizontal conveying path of a packaging machine 10 is shown in FIG. 1, wherein fold boxes 15 are continuously conveyed between pushers 12 disposed at even distances on a conveyor belt 11. The fold boxes 15, which at first lie flat, are taken from a magazine stack by means of removal, raising and transfer devices (not shown), known per se, and are inserted with raised lateral walls between the pushers 12. On their two opposite ends 16, 17, the fold boxes 15 have closure flaps 18, 19, which are bent away in the section of the horizontal conveying path shown, by guide rails, also known and not shown, so that the full opening cross section 22 of the fold box 15 is open. Each fold box 15 (FIG. 2) has in its interior a support frame 25, integrally connected with a wide lateral wall 23 and having interlocking receptacles in the shape of openings 28 for sensitive objects such as ampuls 30 or vials, for example, in wall sections 26, 27 extending perpendicularly from the wide lateral wall 23. A pocket 34 is formed between an intermediate wall 32 c
