Abstract

Apparatus for feeding a number of wrapping machines with chocolate bars or the like, produced continuously and advancing end-on in a procession in more or less regular files and rows comprising a series of successive modules which feed the individual wrapping machines. The modules are preceded by a separator which channels the procession into separate lanes. The modules form part of a conveyor system which advances the articles continuously along a horizontal path. The modules operate in succession to lift the articles in the associated lane from the horizontal path and deliver them to an intermittently travelling cross conveyor leading to one of the wrapping machines. When any packaging machine is unable to accept articles, the articles lifted by its module are returned to the horizontal feed path and the cross conveyor of that module is stopped.

Dependent claims

Apparatus for feeding a plurality of packaging machines with a procession of articles disposed in end-on orientation in rows on an output conveyor from a producing machine, comprising:

a continuously moving conveyor providing a feed path for said articles and aligned with said output conveyor;
a plurality of feed modules spaced in succession along the feed path and including intakes offset laterally with respect to one another to enable each of the feed modules to accept a different row of articles of a cross conveyor associated with each feed module and operative to feed the articles in the associated row to an individual packaging machine in a direction transverse to the feed path;
each feed module including a continuously moving inclined pick-up conveyor for lifting articles in the associated row from the feed path, a continuously moving transfer conveyor including at its delivery end a nose portion extending over the associated cross conveyor, means operative only when the associated packaging machine is in operation for periodically retracting said nose portion to allow articles to fall from said transfer conveyor onto said cross conveyor, and a continuously moving inclined by-pass conveyor for returning articles from the delivery end of said transfer conveyor to the feed path in the event of non-retraction of said nose portion.
