摘要： The invention relates to a blow molding machine for the blow molding of hollow articles, with an accumulator head (1) for producing a preform and with a blow mold for forming a hollow article from the preform. After completion of a blow molding sequence, a piston positioning signal is derived by a control system (15), to regulate the position of a discharge piston (4) in the accumulator head (1), from a comparative signal of the actual position and set position of the discharge piston (4). The set position is determined by integration from a previously specified speed set point profile. The control system (15) further superimposes an influx signal on the comparative signal, which corresponds to the change in volume of plastic flowing from an extruder (2) to replace the discharged contents of the accumulator head (1). The deviation between an actual cushion and a set point cushion for the plastic remaining in the accumulator head at the end of the discharge step is reduced by regulating the rotational speed of the extruder.

摘要： A blow molding machine for the blow molding of hollow articles includes an accumulator head (1) for producing a preform and a blow mold for forming a hollow article from the preform. After completion of a blow molding sequence and the filling of the accumulator head (1), a piston positioning signal is sent by a control system (15) to regulate the position of a discharge piston (4) in the accumulator head (1) derived from a comparative signal of the actual position and set position of the discharge piston (4). The set position is determined by integration from a previously specified speed set point profile. The control system (15) further superimposes an influx signal on the comparative signal, which corresponds to the change in volume of plastic flowing from an extruder (2) to replace the discharged contents of the accumulator head (1). The control system (15) uses the influx signal value determined at the end of a discharge stroke for correcting the set point values for the initial position and the final position for the next discharge stroke. The waiting time between completion of the blow molding sequence and reaching the set point contents level and vice versa is reduced by the control system (15) by controlling the rotational speed of the extruder (2).
