METHOD OF MONITORING OPERATING CONDITIONS OF INJECTION MOLDING MACHINE.

摘要

A method of monitoring, capable of properly, integrally controlling the operating conditions and the operation histories of a group of injection molding machines. Sets of monitoring data delivered from respective injection molding machines are periodically detected by the processor of a monitoring device, and a plurality of the latest monitoring data for respective injection molding machines are updatably stored in a plurality of data tables. When a timer (Ti) relating to any one of the injection molding machines times out or a current injection count (Ri11) reaches a predetermined count (CNi) (206, 216), it is decided a monitoring data output timing has been reached, and, it is further discriminated as to whether the monitoring data are to be printed or displayed on a screen. During a printing process or display process (208, 210, 218 and 220), sets of the oldest monitoring data, sets of the second oldest monitoring data or a group of the oldest data consisting of said both sets of data and calculated monitoring data fluctuations relating thereto are printed or displayed first, and groups of similar data are successively printed or displayed with the oldest one first. When printing or displaying of the group of the latest data including the sets of the latest monitoring data is completed, monitoring data rewriting process is performed (211, 221) in order to update a plurality of sets of monitoring data in preparation for the succeeding monitoring data output.
