Title: Improvements relating to machines for arranging and stacking biscuits or the like
IPC: A21C15/00
Filed: 1936-08-04
Abstract: 479,436. Endless - belt conveyers; partitioned shoots. PATERSON, J. C., and BAKER PERKINS, Ltd. Aug. 4, 1936, No. 21423. [Class 78 (i)] In apparatus of the kind described in Specification 364,648, [Group XVII], for arranging and stacking biscuits or like articles by feeding them between a series of spaced partitions, the partitions are adjustable for different sizes of biscuits and are retained in position magnetically. The biscuits are fed by a conveyer 11 over a bar 12 to an aligning plate 13 having partitions 14 inclined to the direction of travel. They are then carried by an intermediate conveyer 15 over a crest and slide down a plate 17 to a stacking wheel 18 which feeds them in vertical stacked formation across a plate 20 to a delivery conveyer 21. The partitions 14, which are accurately machined to stand vertically on the plate 13, are held in position by a series of permanent magnets 23 (or electromagnets) disposed in transverse recesses in the plate and provided with L-shaped polepieces 24. 25 insulated from the plate. The partitions 38 of the plate 20 are held in a similar manner. Partitions 40 at the forward end of the delivery conveyer 21 are suspended from a support which is recessed to accommodate magnets 44. The intermediate fences 39, 48 are held by a loose tenon and mortise attachment with adjacent partitions. With the arrangements described, the partitions may be composed entirely of soft iron or they may have a strip of soft iron at the base. Alternatively, magnets may be inserted in recesses in the partitions, and the table may be of soft iron. The partitions may be adjusted by means of a grooved gauge rod, and the magnets may be withdrawn (or disconnected in the case of electromagnets) for convenience.
