ABSTRACT:
The invention relates to an apparatus for handling articles in conjunction with the packaging of the same, having a receiving head which is arranged on an extension arm and is intended for receiving at least one article from a supply plane, in particular from a feed conveyor, and for transferring the article to a receiving plane, in particular to a pack which is positioned on a removal conveyor and is intended for the article.
The apparatus of the type mentioned in the introduction serves for handling, for example, chocolates, coffee bags or the like. The articles, which are supplied on the feed conveyor, are to be received, and transferred to a pack for the articles, with the aid of the apparatus. The handling of the articles is to take place automatically—that is to say exclusively mechanically.
The problem on which the invention is based is thus to propose an apparatus which is suitable for grasping articles and for transferring the same to a receiving plane for packaging purposes.
In order to solve this problem, the apparatus according to the invention is characterized in that the extension arm comprises levers which are mounted on linear drives by way of ends or are connected in an articulated manner to one another by way of ends, it being the case that those ends of the levers which are mounted on the linear drives can be displaced by at least two independently controllable linear drives such that at least those ends of the levers which are connected in an articulated manner to one another can be pivoted and, by virtue of these pivoting movements, the receiving head, which is provided on the extension arm, can be raised and lowered in the vertical direction and moved back and forth in the horizontal direction.
The apparatus which is designed in the above manner has a small, straightforward construction. With the aid of the linear drives, the receiving head can be displaced quickly. Accordingly, the apparatus according to the invention is suitable for high operating speeds. Furthermore, with the aid of an apparatus of this type, the receiving head can be displaced to any desired position in space.
The linear drives are preferably fastened on a closed frame, which is arranged above the feed conveyor and removal conveyor, such that carriages of the linear drives can be moved back and forth transversely to the conveying direction of the feed conveyor and removal conveyor. The frame rests on vertical supports which run laterally alongside the feed conveyor and removal conveyor. Accordingly, by way of an apparatus configured in this way, the receiving head can be displaced out of a position above the feed conveyor into a position above the removal conveyor.
According to an advantageous development of the invention, the extension arm comprises two parallel levers, mounted in an articulated manner at their ends in each case, and at least one further lever, arranged at an angle to the parallel levers. In this case, the parallel levers are fastened in an articulated manner, on the one hand, on a common carriage and, on the other hand, on the receiving head. The further lever is connected in an articulated manner to a second, independently controllable carriage and the receiving head. An apparatus configured in this way ensures, by particularly straightforward design means, that the receiving head can be displaced as desired.
