Problems solved by technology

For example, if a wear and tear of a component occurs, as in Figure 9A as well as Figure 9C As shown, even under the same operating conditions, the shape of the curve will change, but if the Figure 9A and Figure 9C (the operating condition is condition A), it is easy to determine the change in the shape of the curve, but even if the comparison Figure 9B and Figure 9C (Condition B is different from condition A in the operating conditions) It is not easy to judge the change of the shape of the curve
[0008] In addition, many types of injection molding machines are produced, and even for a single machine, the conditions may vary significantly depending on the production object, so there is a problem unique to injection molding machines that makes it difficult to process all of these sampled data in the same way. The problem

Embodiment Construction

[0038] A configuration example of a state judging device for realizing the present invention is shown below. However, the configuration of the state judging device of the present invention is not limited to the following examples, and any configuration can be adopted as long as the object of the present invention can be achieved.

[0039] figure 1 It is a functional block diagram showing a schematic configuration of the state judging device of the first embodiment.

[0040] The state judging device 10 can be implemented as a control device for controlling an injection molding machine, or a PC connected to the injection molding machine through a wired / wireless communication line so as to be capable of data communication with the injection molding machine, for example. The state judging device 10 includes: a preprocessing unit 12 for preprocessing data acquired from an injection molding machine; an internal parameter setting unit 14 for setting fixed internal parameter values;...

Abstract

A state determination apparatus for determining a state related to an abnormality of an injection molding machine based on an operation state of the injection molding machine includes a machine learning apparatus for learning the state related to the abnormality of the injection molding machine. The machine learning apparatus observes, as a state variable that represents a current state of an environment, injection data that indicates the operation state of the injection molding machine, acquires label data that indicates the state related to the abnormality of the injection molding machine, and performs learning by associating the observed state variable with the acquired label data.

Description

technical field [0001] The present invention relates to a state judging device for judging an abnormal state related to the injection molding machine based on the operating state of the injection molding machine and assisting maintenance of the injection molding machine. Background technique [0002] The maintenance of the injection molding machine is carried out regularly or when an abnormality occurs. As one of the methods for judging the status of the injection molding machine during maintenance of the injection molding machine, there is the following method: During the mold opening and closing operation or the molded product ejection operation in the injection molding cycle of using the injection molding machine to mold the molded product, the corresponding time Or use the position of the movable part to drive the load state of the motor of the movable part as a reference load, and record it in a memory at a predetermined sampling cycle, and make the recorded reference l...
