PURPOSE:To contrive to rationalize the preparatory running and automatic normal running by a method wherein both control units to control the actuations of facilities, which require the change of running conditions at the preparatory running of a molded item, and those, which require no change of running conditions at that time, are linked to a centralized control equipment, which instructs running conditions necessary for the production at the preparator running and the successive normal running. CONSTITUTION:At the preparatory molding, the code number, production quantity of a product to be molded are transmitted from a centralized control equipment 10 to respective control units 1a-8a. Among the resultant control units, the control units of facilities, which necessitate the change of running conditions at the preparatory running, read running condition data necessary for preparatory running from respective memories. After that, at every molding of product during preparatory running, a shot count is transmitted from the control unit 1a of an injection molder 1b to the respective control units 2a-8a and the centralized control equipment 10. At the control units 2a-8a, the preparations for preparatory running and the changing-over of running conditions are executed. On the other hand, after once the molding starts and the changing-over of product type stabilizes or during normal running, the centralized control equipment 10 instructs normal running to the respective control units 1a-8a. As a result, the respective control units read running condition data necessary for the normal running for every product type from the respective memories in order to execute them. |
