    • In a programmable controller system, a sequence program, an operation sequence control program module and a plurality of I/O control program modules including interlock control are independently provided. In the interlock control of the start condition and the operation end condition of an actuator, an interlock condition set program is separated from the operation sequence control program, and the interlock condition is described in a table, thereby easily setting the interlock condition in the form of a table. As described above, when the operation sequence control program executed by a programmable controller and the input/output control program including the interlock control are independently provided, the number of steps in programming can be decreased, and reliability and maintenance performance of the program can be improved.

    • An injection molding apparatus includes an electrically driven injection apparatus in which a screw accommodated in a heating cylinder is driven by a motor. The injection apparatus includes a pressure detection device for detecting an injection pressure of the screw and a device for detecting a stroke of the screw. Speed control is first conducted until the preset packing rate which represents that a dwell process is almost started is obtained, and the remaining injection process and the dwell process are conducted using an output of the pressure detection device. If a volume of resin in the cylinder which is required to fill the cavity is obtained beforehand, a packing rate of the molding material in the cavity is obtained by detecting the screw stroke. A packing rate which represents that the dwell process is nearly started is preset, and speed control of the screw is conducted and the resin is thereby packed at a fixed injection rate until when that preset packing rate is obtained. In the remaining injection process and the subsequent dwell process, a desired screw thrust is obtained using the output of the pressure detection device which detects the injection pressure of the screw.
    • 注射成型装置包括电驱动注射装置,其中容纳在加热缸中的螺杆由马达驱动。 注射装置包括用于检测螺杆的注射压力的压力检测装置和用于检测螺杆行程的装置。 首先进行速度控制,直到表示停留处理几乎开始的预设填充率,并且使用压力检测装置的输出进行剩余的喷射处理和停留处理。 如果预先获得填充空腔所需的圆筒体积的树脂,则通过检测螺杆行程来获得模腔中的模塑材料的填充率。 表示停留过程几乎开始的填充率是预先设定的,螺杆的速度控制被进行,并且树脂以固定的喷射速率被包装,直到获得预设的包装率。 在剩余的注射过程和随后的停留过程中,使用检测螺杆的注射压力的压力检测装置的输出获得期望的螺杆推力。
