Claim 1
Independent Claim
202 words
Apparatus for transferring package articles from an article packaging machine to a box-packing machine, comprising: storage means for storing a predetermined supply of said packaged articles in a supply shaft; transfer means for transferring packaged articles from said packaging machine directly to said box-packing machine; means for diverting defectively packaged articles away from said box-packing machine so that defectively packaged articles do not reach said box-packing machine; means for replacing the defectively packaged article directly with a packaged article from said supply shaft in said storage means without interrupting the flow of packaged articles to said box-packing machine; said transfer means transferring the packaged article from said supply shaft to said box-packing machine at a location in substantially close proximity to said box-packing machine for replacing said defectively packaged article, said packaging machine being substantially distant from said box-packing machine compared to the distance between said supply shaft and said box-packing machine; said transfer means having a gripper for picking up and advancing packaged articles leaving said article packaging machine; said supply shaft having an opening for the passage of articles to said supply shaft and from said supply shaft, said opening being positioned in a path of conveyance of said gripper.
