残りの不良が多い場合は圧力を下げたりして調節する。Next, an example of the automatic control system for the molded product of the present invention will be described by injection molding. With the injection molding machine (1a),
The molten resin is molded under preset molding conditions such as the amount of resin supplied to the mold, the temperature of the molten resin, the temperature of the mold, the injection pressure, and the molding time to obtain a molded product. The molded product is taken out of the mold by the take-out machine (10), and the molded products are sandwiched one by one by the aligning machine (2) and aligned on the conveyor (3).
Finishing machine (4) for molded products conveyed by conveyor (3)
And the shot material such as glass powder is sprayed at high pressure. Next, it is conveyed to the appearance determination device (5), and it is determined whether the molded product is a good product or a defective product based on the difference between the outer surface of the molded product set in advance as a non-defective product and the outer surface of the molded product captured by the camera. . An instruction signal from the appearance determination device (5) is sent to the sorting machine (6), and the molded product determined to be defective is removed.
Further, the generation degree of defective products sorted by the sorting machine (6) is totaled by the totaling machine (7) for each defective item. The result totaled by the totalizer (7) is displayed on the television screen. In the present invention, the results aggregated by the aggregator (7) are sent to the defect rate determination device (8) to determine whether the frequency of occurrence of defective products is higher than a preset level. When it is determined by the defect rate determination device (8) that there are many defect levels,
An output signal is sent from the defect rate determination device (8) to the controller (9). The controller (9) sends an instruction signal to the injection molding machine (1) based on the state of the generated defective rate.
Then, the amount of resin for molding the molded product, temperature, and pressure are adjusted. For example, when there are many defective defects due to insufficient material, the amount of resin is increased, and when the molded product has many residual defects due to burrs, the pressure is reduced to adjust.

る。As described above, the occurrence frequency of defective products is determined by the defect rate determination device (8), and the controller (9) instruction signal that receives the output signal from this defect rate determination device (8)
Since the amount of resin for molding the molded product, the temperature, and the pressure can be quickly adjusted, the occurrence of defects can be minimized. Furthermore, since the amount of molding resin, temperature, and pressure are continuously adjusted, consistent production is possible.
