Buttering Machine


The specification for this project was to develop a fully automatic buttering machine for a bakery, where an exact amount of butter is applied to each slice with an appearence of manual spreading.


The control system consisted of an Allen-Bradley Powerflex Inverter to drive the twin belt conveyors, with the two butter extrusion applicators driven by two Ultra 3000 Indexing AC servo drives. The sequence control was done by a SCL 5/05 PLC and the software was developed using RS Logix.
