摘要:
When text information is inputted as electronic data from an operation panel of a display apparatus, which functions as a human-machine interface of an injection molding machine, an operation panel controller of the display apparatus stores the electronic data of the inputted text information. When an instruction to display text information is emitted from the operation panel, the operation panel controller displays the stored electronic text information in the display apparatus, according to the instruction.

The present invention is directed to a method of monitoring operation data for quality control with a little possibility that a nondefective product is mistakenly determined as a defective product even if the operation data fluctuates in a large waviness curve. Every time an operation data piece for quality control is obtained, a moving average of the predetermined number of data pieces lately obtained is calculated. When the deviation of a data piece from the moving average exceeds the tolerance limit, an alarm is generated. By employing the method of the present invention for monitoring operation data such as charging time, injection time and the amount of cushion in an injection-molding machine, the accuracy of determination as to a defective or nondefective can be improved.

Operation state information for each cycle of manufacturing operations of each of injection molding machines 300 is acquired by a center management terminal device 400 via a network from a plurality of controlling terminal device 400 for controlling the injection molding machines 300. Cumulative utilization of replacement parts of each injection molding machine 300 put into practical operation is recognized by the operating condition recognizing section of the center management terminal device 400 based on the parts state information for the replacement parts of each injection molding machine 300 included in the operating state information. Based on the cumulative utilization, availability of the parts is recognized with reference to lifetime information concerning lifetime of the parts previously stored in the center storage section, and situation of the availability is displayed with a different display format on the center terminal displaying section 503.
摘要:
A screw is incorporated into a heating barrel. A ball screw is connected to a rear end portion of the screw through a load cell, and a servomotor for injection is connected to the ball screw. First, the heating barrel is retreated and separated from a mold, and the screw is moved to the half stroke position. After the screw is advanced for a preset period of time, the servomotor is stopped by automatic decompression to detect an output of the load cell. Similarly, after the screw is retreated for a preset period of time, the servomotor is stopped by automatic decompression to detect an output of the load cell. An average of outputs of the load cell after the screw advances and retreats is calculated and considered to be an output of the load cell under no-load conditions, thereby performing zero adjustment of the load cell.
摘要:
A stationary die is held on the front surface of a stationary platen and a movable die is held on the front surface of a movable platen. A plurality of monitoring sections are set in advance within a moving range of the movable platen and an upper limit of forward thrust of the movable platen is set for each of the monitoring sections. When the forward thrust of the movable platen reaches the upper limit set in one of the monitoring sections during a die closing operation, it is determined that abnormality occurs to stop the movable platen from moving forward. If a die closing mechanism is of a toggle link type, the forward thrust of the movable platen is calculated based on the thrust of a crosshead which drives a toggle link mechanism, the moving speed of the crosshead, and the moving speed of the movable platen.
