ABSTRACT:
An apparatus for feeding a plurality of pharmaceutical product simultaneously onto a matrix of formed blister webbing is provided. The dedicated feeder structure is held within a housing which incorporates a plurality of hanger plates for easy manual exchange and replacement of the feeder component subsystems called "change parts". These components include a reciprocating bin carried on a platform for simultaneously delivering a plurality of product in a desired matrix format. A plurality of entrance chutes, assembled into the matrix formation simultaneously feeds the product downward from the bin. A horizontally operated shuttle gate having a plurality of product orifices operates to simultaneously open and close each chute and to transfer the respective matrix of product to a release guide structure which may be implemented as a template or a plurality of release chutes. The release guide structure feeds the matrix of formed blister webbing. Entrance chute, shuttle gate and release guide structure surfaces which can or may contact product are preferably contoured in crossection to conform to product shape and coated or plated with a friction reducing surface to promote steady and continuous product movement or flow. Bin movement is accomplished by reciprocating motion provided by a crank shaft drive structure which operates in a sealed enclosure. This structure lifts and lowers a platform which carries the bin. A pair of juxtaposed slide bars operating on respective spaced apart and aligned shafts carry the shuttle gate.
