JPS6445618A - Disposition of abnormal action of machine - Google Patents

Abstract

PURPOSE:To enable early attendance even during unmanned operation and contrive to improve the safety and yield by a method wherein the operation of a machine is stopped at the source of action of the machine after the completion of one cycle through the continuation of operation together with the indication of the content of abnormality. CONSTITUTION:Though monitoring times are set on the same setter, the monitoring time of the quality of a molded item is different from that of the abnormal action of machine in length. As a result, the monitoring time of the action of machine is given by increasing, for example, by several 10%, which is calculated through program by reading the set value on an injection upper limit time setting display 1 by a CPU 8 so as to store said information in a memory 9 as the set value of the monitoring time of the abnormal action. In an injection process, for example, if the practical value exceeds the set value of the monitoring time of the abnormal action of machine, the abnormal process is displayed on a register section 5. At the same time, the injection process is completed, and the operational action is proceeded to the next process. Finally, one cycle is completed and the operation of the machine is stopped at the actional origin of the machine. Further, in a plasticizing process, the abnormality is also disposed similarly.
