Abstract

Abstract A machine for packaging flexible articles, e.g. disposable diapers, which includes mechanism for forming a stack containing a predetermined number of articles including devices for moving the stack and pushing it into a suitable container. The machine includes an infeed conveyor section used to convey and compress the articles whereupon they are ultimately delivered into successive slots of a pad wheel. The articles are stripped from the slots and simultaneously formed into stacks containing a predetermined number of articles. A pusher element and a stack controller arm are provided to convey each stack into the pocket of an intermittently rotating stack wheel. The stack wheel moves successive stacks into alignment with a support plate whereupon a transfer pusher moves each successive stack fully onto the support plate. A tamper plate is provided to exert a small amount of compressive force on the stack prior to lateral movement of the stack between the support plate and a ceiling plate which is adjacent the tamper plate. A reciprocating side pusher is used to move the stack laterally into position for ultimate movement into a container. A container wheel is intermittently rotated alongside the support plate. Container supporting nozzles project from one side of the container wheel, there being a container telescoped over each of the nozzles. When a nozzle containing an empty container is moved into contiguous relationship with the article stacks, a container load pusher is actuated to move the stacks into the container whereupon on further indexing of the container wheel, the filled container is removed by a full container pusher.

Claim 2
Dependent Claim 139 words
A machine for packaging flexible articles comprising the combination of: a. means for forming a plurality of articles into a stack containing a predetermined number of articles, b. means for conveying and moving said stack onto a support plate, c. means for compressing said stack on said support plate, means for thereafter moving said stack into position on said support plate for insertion into a container, and means for continuously maintaining said stack in compressed condition during movement thereof on said support plate, d. means adapted for receiving and supporting a container in an article receiving attitude including means for aligning said container supporting means with said stack of articles, and e. means for pushing said stack of articles into a container while said stack is maintained under compression by said means for maintaining said stack in compressed condition.
Claim 3
Dependent Claim 73 words
A machine for packaging flexible articles as claimed in claim 1 wherein said stack forming means comprises a pad wheel having a plurality of spaced arcuate slots on its periphery, means for depositing articles into the slots thereof and a stripper plate for intercepting a leading edge of each article while supported in a slot to remove the articles from said slots and form a stack of superposed articles on said stripper plate.
Claim 4
Dependent Claim 71 words
