Abstract

PURPOSE:To simplify the operation of injection molding as well as to save power required for the injection molding process by using a system in which plural defective moldings can be discharged even after error signal output is inhibited by restoring an injection condition for an injection molding machine to within an allowable range in such a way as to regulate the intermixture of defective products in a collecting yard. CONSTITUTION:When judging the fact that even one of the detection signals SS1-SSn of injection conditions is out of an allowable range, a control circuit 1 for a molding machine sends out an error signal E to a stripping control circuit 2. The signal ES is sent out from the circuit 2 to the control circuit 3 which sends out a corresponding signal AS2 to the second memory 6 and reads out a pattern data PD2 while incrementing address in sequence to send it out to the circuit 2. The circuit 2 sends out the data PD2 to a stripper 5 for discharging defective products. Then, when the injection conditions are restored to the allowable range and the output of error signal ED is inhibited, the circuit 2 actuates its counter 2a and leads a signal ES corresponding to the circuit 3 to be sent out in such a way that the stripping and discharging operations of defective products can be performed according to the preset stripping number.
