ABSTRACT:
A disconnect assembly releases a conveyor chain from a driven shaft. The connection between the driving shaft and the chain is by means of tapered pins associated with a driven plate or hub received in tapered holes on a plate attached to the driving shaft. The driven plate or hub carries a sprocket for the chain drive. An overload on the chain drive causes the tapered pins to ride out of the recesses. This activates a pressure cylinder that continues to withdraw the pins for a positive disconnect. Also, the pressure cylinder can bring about a disconnection on command. Limit switches detect a disconnect and then permit restarting the conveyor only when the chain and its drive are appropriately positioned. A set of disconnect plates located on the driving shaft engage rollers that both activate the disconnect and transmit its condition to the limit switches.
