BRIEF SUMMARY
This application is a 35 U.S.C. 371 of PCT/DE97/00446 filed Mar. 7, 1997.
The invention is based on a device for introducing items, in particular filled flat bags, into cartons, of the kind disclosed for instance by French Patent 1 537 812. In the known device, the flat bags pass from a vertically arranged discharge gate device onto a horizontally displaceable, raisable and lowerable conveyor plate that positions the flat bags below a suction head. Once the flat bags have been received from the conveyor plate by means of the suction head, the conveyor plate is retracted, so that the suction head can deposit the flat bags in one of a plurality of cartons arranged on a conveyor belt below the suction head. If a flat bag is to be deposited into a particular carton by means of the known device, it is necessary for the applicable carton to be moved below the suction head by adjustment of the conveyor belt. When a plurality of cartons are located on the conveyor belt, this requires a conveyor belt of complicated design. Moreover, during the adjusting of the conveyor belt, it is as a rule impossible to place any other flat bag into a carton at the same time. The object of the invention is to improve a device for introducing items, in particular filled flat bags, into cartons, in such a way that it prevents the disadvantages in terms of flexibility and capacity known from the prior art for complex applications, and at the same time enables a compact design. Further advantages and advantageous refinements of the device according to the invention for introducing items, in particular filled flat bags, into cartons will become apparent from the the description set forth hereinafter.
BRIEF DESCRIPTION OF THE DRAWINGS
One exemplary embodiment of the invention is shown in the drawing and will be described in further detail below.
FIG. 1 shows a device for introducing items, in particular filled flat bags, in a simplified perspective view; and
FIG. 2 shows part of the device of FIG. 1 in a simplified longitudinal section.
The device 10 for introducing items, in particular filled flat bags 1, into cartons 2 has a bag delivery device 11, embodied as a belt conveyor, on which the flat bags 1 are arranged in a line, spaced apart from one another, and delivered to the device 10 in the direction X. In the region of the device 10, the bag delivery device 11 has three successive feed shunts 12, 13, 14. The feed shunts 12, 13, 14, and the bag delivery device 11 together form a common conveying plane. Each of the feed shunts 12, 13, 14 is likewise preferably embodied as a belt conveyor. In addition, each of the feed shunts 12, 13, 14 is pivotable between two end positions, on the side remote from the bag delivery device 11, each being pivoted in a respective horizontally disposed pivot shaft 16, 17, 18. In the first, lowered end position, the feed shunts 12, 13, 14 form one common horizontal conveying plane for incoming flat bags 1. In the other end position, the side of the feed shunts 12, 13, 14 facing toward the bag delivery device 11 is raised by at least a height equivalent to the height of one flat bag 1.
In coincidence with and below the feed shunts 12, 13, 14, each feed shunt 12, 13, 14 is assigned a slide plate 20 and a vacuum turntable 21, 22, 23. For the sake of simplicity, the slide plate 20 is shown in FIG. 1 only below the feed shunt 13, but the other two feed shunts 12, 13 also have identically embodied slide plates 20. The slide plates 20 serve to transfer the flat bags 1 from the plane of the belt delivery device 11 or of the feed shunts 12, 13 to the vacuum turntables 21, 22, 23. The vacuum turntables 21, 22, 23 adjoin the slide plate 20 as gaplessly as possible, and extend parallel to and below the belt delivery device 11. In FIGS. 1 and 2, the slide plate 20 is shown embodied in an S shape. However, it may also be embodied as a flat plate, for example. The vacuum turntables 21, 22, 23 are likewise not restricted to a rectangular shape. What is essential is merely that a transition that as much as possible is
