PACKAGING INSTALLATION FOR BATCHES OF PRODUCTS
First Claim
1. A packaging installation for batches of products comprising, distributed on a single common frame:
- an infeed conveyor on which said products are arranged by batches, originating from a preparation and grouping station,an outfeed conveyor which removes said products in the form of batches to a packing machine and, between said infeed and outfeed conveyors,a module for forming a wrapping, of the tray type or the wrap-around type, comprising, on the one hand, a cleated belt conveyor constituted by two continuous belts forming a first slider bed which extends between said infeed conveyor and said outfeed conveyor, said continuous belts being adjustable transversally in order to alter the width of said first slider bed, and, on the other hand, an apparatus for folding and forming the wrapping, arranged above an end portion of said first slider bed,said installation comprising means for retracting said continuous belts and means allowing the substitution of said continuous belts by a conveying system capable of allowing simple passages of naked batches of products between said infeed conveyor and said outfeed conveyor, said substitute conveying system being inserted between said continuous belts in order to form a second and continuous slider bed between said infeed conveyor and said outfeed conveyor.

Abstract
The installation comprises an infeed conveyor (7) and an outfeed conveyor (8) with, between the two, a module (5) for forming a wrapping of the tray or wrap-around type, the cleated belt conveyor (11) of which is constituted by two continuous belts (11a, 11b) which are retractable so as to allow the installation of a substitute conveying system (13) which is capable of forming a continuous slider bed between said infeed conveyor (7) and said outfeed conveyor (8).
This arrangement makes it possible to provide a versatile installation which is capable of carrying out on the one hand, wrapping operations with blanks of the tray or wrap-around type and on the other hand, simply transporting batches of products, said products being, for example, placed on supporting cardboard sheets so as to convey them to the packing machine to receive a plastic film and then into the heat-shrink tunnel to complete the wrapping.
