摘要： A restoration work information storage unit stores a work item for restoration that is set for each location at which an abnormality is expected to occur in equipment to be managed, and priority information indicating a priority of execution for each of the work items. Upon detecting that an abnormality has occurred in the equipment and an operation of the equipment has been stopped, a restoration assist information generation unit generates restoration assist information, in which the work items for restoring the equipment are arranged in the order of execution according to the priority information, based on information of a location at which the abnormality has occurred. Upon detecting that a state of any location in the equipment has changed before a restoration work based on the restoration assist information is completed, a restoration assist information update unit updates the restoration assist information.

摘要： Different divided tools are attached to tool attachment portions using automatic tool changers in proximity to slit tools that have already been attached to tool attachment portions. The attached different divided tools are moved toward the previously attached divided tools using the automatic tool changers, and the different divided tools are caused to abut on the previously attached divided tools. In a case in which a torque of a servomotor for moving the automatic tool changers in a left-right direction has reached a setting value set in advance, the different divided tools are detected to have abutted on the previously attached divided tools, and the moving of the different divided tools is stopped.

摘要： An automatic tool changer includes first and second tool change units that is driven respectively by a pair of servo motors and move along an arrangement direction of a plurality of tools installed on a tool installation unit, a torque detection unit that detects a torque of each of the pair of servo motors, and a control device that controls operations of the first and second tool change units. The control device fixes the first tool change unit at a reference position, and moves the second tool change unit toward the first tool change unit. The control device determines, based on a torque change of each servo motor, that a plurality of upper tools are brought together at the first tool change unit as a result of a movement of the second tool change unit.
