Claims
- 1. Transfer means for transferring flat-sided boxes between a pair of first and second conveyors disposed in different horizontal planes, the first of the conveyors moving a box in the process of being folded along a folding mandrel toward a discharge end of the mandrel and the second conveyor receiving the folded box discharged from the mandrel for transporting the received box to a filling machine, the second conveyor extending along a different path beneath the first conveyor, and comprising:
- a plurality of mutually spaced box carriers supported by arms attached to a horizontal shaft for rotational movement about an axis disposed between said planes at the end of the conveyor associated with the mandrel which axis extends at a first 45.degree. angle as respects the horizontal axis of the direction of travel of the first conveyor in its horizontal plane of travel, said carriers being disposed at a second 45.degree. angle as respects the rotational plane of movement of said arms about said axis so that when said shaft is rotated 360.degree. the axis of each carrier is sequentially aligned first to the axis of said first conveyor and 180.degree. later is at right angles to the axis of the first conveyor,
- an indexing means for effecting incremental movement of said first conveyor and like incremental movement of said box carriers about said axis of said horizontal shaft in unison to accommodate feed of said boxes from the discharge end of said mandrel individually to related ones of said container carriers for transfer individually to the second of said conveyors, thereby to invert and turn said boxes 180.degree. about their longitudinal axes and 90.degree. about their transverse axes, respectively, with respect to said first conveyor;
- each carrier being pocket-shaped in cross section and presentable to the discharge end of said mandrel laterally to receive and to hold a box in provision of its transposition and transfer between said conveyors, each said carrier being presentable in juxtaposed relation to and above said other conveyor to discharge a box radially from a related carrier to said other conveyor, and means effective at the time of juxtaposition to transfer a box from each said carrier to said other conveyor upon completion of inverting the box 180.degree. and turning said box through said 90.degree. angle;
- the discharge end of said mandrel being defined by a 45.degree. angle when viewed in top plan and the end adjacent thereto of each carrier being defined by a mating 45.degree. angle so the horizontal axis of each pocket is substantially coincident to the horizontal axis of the mandrel each time a 45.degree. end of a pocket is mated to the 45.degree. end of the mandrel.
