ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to feed devices or palletizing plants.
BACKGROUND OF THE INVENTION
Known palletizing plants enable stacks of goods of one and the same type to be formed into layers, each layer being formed from several adjacent stacks of the same product. The layer forming device varies in known plants depending on the type of product to be palletized. Hence if the type of product varies, the type of layer forming device also has to be changed. This represents a limit in current plants in that to change the feed device in those palletizing plants in which this is possible, the plant has to be halted for a certain time with a resultant loss of production.
SUMMARY OF THE INVENTION
The object of the present is to overcome the aforesaid drawbacks by providing a layer-forming device able to operate on at least two different types of product, for example bottles and boxes. The feed device of the invention comprises at least two parallel, coplanar lines arranged side-by-side to form at least one row of different products on each of them. The lines are positioned in front of a moving accumulation surface, such as a conveyor belt, on which the layers of products are formed. Each of said at least two lines can be fed with a certain type of product by a usual conveyor means positioned upstream of it.
The present invention comprises a movable pusher able to transfer that portion of the product row facing said moving accumulation surface from one of said at least two row-forming lines to said surface. There are also provided means to form layers from rows of products of one and the same type and means for compacting said layers. According to the present invention the movable pusher is suspended from an upper guide and is free to move in a vertical direction. It is also provided with means for interacting with two different types of product.
In order to clarify the operational and constructional characteristics of the invention a preferred embodiment thereof is described hereinafter by way of a non-limiting example and illustrated on the accompanying drawings.
