Apparatus for orienting, stacking and loading patties into cases

摘要

An apparatus and method for stacking and loading disc-like objects into receptacles is provided. The apparatus includes a lane combining conveyor which receives multiple lanes of product and combines one or more of the outer lanes into the remaining lanes. A stack former is provided for forming individual stacks of patties which are side supported onto rails. The rails can be pivoted down to divert patties for clearing jams. After the product is formed on the stack formers, a stack transfer mechanism transfers the stacks of products formed on the stack forming rails to the matrix former. Matrix former receives individual rows of multiple stacks from the stack transfer mechanism. A stripper mechanism is used to ensure that the stacks are not scrambled during this transfer. Once the matrix former is filled with product, a case rollover mechanism is rotated to the matrix former. Both the case and the matrix former are rotated back together to bring the case to the upright position and transfer the stacks into the case. The matrix former is then removed from the case with a vertical motion and rolled back into position to receive stacks from the stack transfer mechanism.
