Butter unwrapper system

May 7, 2014
Designed for use with butter bulks entering a processing line, the SPX butter unwrapper system also can be utilized for a variety of other heavy packaged products. The machine is controlled by a PLC with an intuitive touch screen operator interface. De-boxed butter is received into the machine on an inlet conveyor belt. A table, operated by air, turns and manipulates the block of butter to enable the operator to unwrap it without lifting. Unwrapped butter then leaves the machine on another conveyor belt connected to the required downstream processes. The system’s sensors monitor the position of the butter bulks and communications to interface with upstream and downstream equipment.
