ABSTRACT:
A paperboard carton piercing-crushing and recycle system and apparatus which includes a safety operated door which controls motor operated carton piercing and crushing rolls in order to crush paperboard cartons for disposal. The safety operated door is provided with a magnetic switch which controls two different timed electrical circuits. One circuit controls an electronic safety latch mechanism which prevents the carton disposal door from opening during operation of motor driven carton crushing rolls and one timed circuit operates the motor during the time that the electronic safety latch mechanism prevents the door from operating. When the motor circuit stops, the timer to the electronic safety latch mechanism releases the safety latch so that the door can be opened. Thus, the system is safe and will not operate if the carton disposal door is open.
