PURPOSE:To restore the operation of a waste push-in apparatus to a normal state, by automatically removing the bite-in of waste. CONSTITUTION:When the waste is bitten in between a push-in plate 5 and an inlet port 3, a first cylinder C1 is overloaded. As a result, the pressure of working oil in a discharge passage 8 rises to turn on a pressure switch PS to energize a timer relay. Then, a solenoid SOL1 is de-energized and another solenoid SOL2 is energized to stop the forward motion of the push-in plate 5 and start its backward motion. Thereafter, the solenoid SOL2 is de-energized and the solenoid SOL1 is energized to stop the backward motion of the pushin plate 5 and start its forward motion. The bite-in of the waste is thus automatically removed. |
