Abstract
Abstract A method and apparatus for setting up and loading a tray includes means for withdrawing collapsed trays from a hopper and for forming those trays into a tubular structure and for subsequently manipulating end closure panels so as to close the ends of the tray, means for depositing the tray at a loading station together with article handling mechanisms for removing articles from a receiving station and then for transporting the articles to the loading station where the articles are released into the apertured top panel of the tray.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
149 words
In a loading system for removing a group of articles from a receiving station and for depositing the group of articles at a loading station and including support structure rotatable about a vertical axis and disposed between said stations, a pair of substantially identical article handling mechanisms mounted on said support structure and arranged to swing thereabout, said mechanisms being arranged for simultaneous disposition at said stations respectively and wherein the improvement comprises a pair of vertically reciprocable support brackets mounted in diametrically opposed relation on said support structure and interconnected with said article handling mechanisms respectively, a support ring disposed about said brackets and slidably connected therewith so as to accommodate rotation of said brackets and mechanisms about said vertical axis, and means for tilting said support ring into and out of a horizontal plane to vertically reciprocate said support brackets and said article handling mechanisms connected thereto.
Claim 2
Dependent Claim
149 words
In a loading system for removing a group of articles from a receiving station and for depositing the group of articles at a loading station and including support structure rotatable about a vertical axis and disposed between said stations, a pair of substantially identical article handling mechanisms mounted on said support structure and arranged to swing thereabout, said mechanisms being arranged for simultaneous disposition at said stations respectively and wherein the improvement comprises a pair of vertically reciprocable support brackets mounted in diametrically opposed relation on said support structure and interconnected with said article handling mechanisms respectively, a support ring disposed about said brackets and slidably connected therewith so as to accommodate rotation of said brackets and mechanisms about said vertical axis, and means for tilting said support ring into and out of a horizontal plane to vertically reciprocate said support brackets and said article handling mechanisms connected thereto.
Claim 3
Dependent Claim
31 words
A loading system according to claim 1 wherein said support structure includes a vertically disposed rotatable shaft interconnected with a common driving mechanism for imparting rotary movement to said support structure.
Claim 4
Dependent Claim
28 words
A loading system according to claim 2 wherein said driving mechanism is arranged to drive said shaft intermittently and to afford dwell intervals interspersed between periods of rotation.
Claim 5
Dependent Claim
20 words
A loading system according to claim 3 wherein said support ring is tilted only during dwell intervals of said shaft.
Claim 6
Dependent Claim
36 words
A loading mechanism according to claim 4 wherein operating means is interconnected with both of said mechanisms for causing engagement and disengagement of groups of articles at said receiving station and at said loading station respectively.
Claim 7
Dependent Claim
28 words
A loading system according to claim 5 wherein said operating means is arranged to effect engagement and disengagement of the articles only during dwell intervals of said shaft.
Claim 8
Dependent Claim
56 words
A loading system according to claim 5 wherein cam means is arranged to impart simultaneous movement to a pair of arms to cause those arms to engage a part of each of said mechanisms to cause said mechanisms respectively to engage and disengage the groups of articles at said receiving station and at said loading station.
Claim 9
Dependent Claim
26 words
A loading system according to claim 1 wherein a tray is moved into said loading station by motive means operable in synchronism with said transport means.
Claim 10
Dependent Claim
51 words
A loading system according to claim 8 wherein said motive means is arranged to move said tray incrementally while in said loading station so as to accommodate a plurality of loading operations of at least one of said article handling mechanisms while a single tray is disposed at said loading station.
Claim 11
Dependent Claim
24 words
A loading system according to claim 1 wherein synchronously operable conveyor means is arranged to supply a group of articles to said receiving station.
Claim 12
Dependent Claim
29 words
A loading system according to claim 1 wherein said receiving and said loading stations are disposed at different levels and wherein said article handling mechanisms are relatively movable vertically.
Claim 13
Dependent Claim
28 words
A loading system according to claim 1 wherein said support structure is rotatable to move said article handling mechanism between said loading and said receiving stations in sequence.
Claim 14
Dependent Claim
35 words
A loading system according to claim 1 wherein a pivotally mounted operating member is mechanically connected with said ring for imparting tilting movement thereto thereby to impart simultaneous vertical movement to said article handling mechanisms.
Claim 15
Dependent Claim
54 words
A loading system according to claim 1 wherein each of said mechanisms comprises a plurality of horizontally spaced articles engaging elements disposed about the article, each of said elements being angularly movable about a substantially vertical axis, and each element having an article engaging surface and an article clearing surface disposed about its periphery.
