Automatic inspection device for corrugated paperboard machine, and corrugated paperboard machine

A corrugated paperboard machine comprising:

• a plurality of machining tools for subjecting a corrugated paperboard to machining;
• a tool moving mechanism including a plurality of movable members each coupled to a respective one of the plurality of machining tools, a support member movably supporting the plurality of movable members, and a plurality of drive motors for moving respective ones of the plurality of movable members along the support member;
• a mode setting section for setting an inspection mode;
• a position setting section for, when the inspection mode is set, setting the plurality of movable members to positions located, respectively, within a plurality of moving ranges each defined along the support member correspondingly to a respective one of the plurality of movable members;
• a control section for, when the inspection mode is set, driving each of the plurality of drive motors at a given rotational speed so as to allow a respective one of the plurality of movable members to be moved within a corresponding one of the plurality of moving ranges;
• a current detection section for detecting a drive current being supplied to each of the plurality of drive motors when the drive motor is driven at the given rotational speed by the control section;
• a current determination section for determining whether or not the drive current of each of the plurality of drive motors detected by the current detection section exceeds a given threshold;
• and
• a defect detection section for, when the current determination section determines that the drive current of a specific one of the plurality of drive motors exceeds the given threshold, detecting that a defect occurs in the movable member driven by the specific drive motor or in a portion of the support member corresponding to the moving range of the movable member driven by the specific drive motor.

An automatic inspection device for a corrugated paperboard machine having a plurality of tool moving mechanisms, each of the tool moving mechanisms comprising a movable member coupled to a tool for subjecting a corrugated paperboard to machining or operation;

• a support member movably supporting the movable member;
• and a drive motor for moving either one of the movable member and support member so as to move the movable member along the support member, the automatic inspection device comprising:
• a control section for driving each of the drive motors of the plurality of tool moving mechanisms, at a given rotational speed;
• a current detection section for detecting a drive current being supplied to each of the drive motors when the drive motor is driven at the given rotational speed by the control section;
• a current determination section for determining whether or not the drive current of each of the drive motors detected by the current detection section exceeds a given threshold;
• and
• a defect detection section for, when the current determination section determines that drive current of a specific one of the drive motors in the plurality of tool moving mechanisms exceeds the given threshold, detecting that a defect occurs in the movable member driven by the specific drive motor or in the support member supporting the movable member driven by the specific drive motor.
