Description

  The present invention relates to an abnormality monitoring image management apparatus, which is suitable for application to, for example, an injection molding machine monitoring apparatus.

  Conventionally, for example, as a monitoring device for an injection molding machine for injection molding of a synthetic resin material, an injection molding machine based on a video signal obtained by capturing an image around a mold of a main body of an injection molding machine with a television camera as an imaging means What is used to determine whether or not the injection molding operation of the insert molding of the main body is normal (see Patent Document 1).

  The injection molding machine body repeats the injection molding cycle every time one injection molding machine product is molded.

  That is, the injection molding machine main body is in a state where the insert metal fitting is set in an appropriate place by the operator's manual operation with respect to the lower metal mold, and then the upper metal mold is moved to contact the lower metal mold. (This state is called the clamped state). By injecting a synthetic resin material between the lower mold and the upper mold, which are insert molds, an injection molded product integrated with the insert metal fitting is molded. To do.

  When the injection molded product attached to the lower metal fitting retreats to a position away from the lower mold that is the fixed mold, the upper mold that is the movable mold (this state is referred to as the mold open state). It is ejected from the lower mold by the ejecting pin (this state is called an ejecting operation state) and taken out by the take-out machine.

  Thus, when one injection molded product is taken out from the main body of the injection molding machine, one cycle of the injection molding process (that is, one injection molding cycle) is completed and the next injection molding cycle is started.
