摘要:
A maintenance management system for a press line which enables even one person to carry out efficient maintenance operations. For this purpose, in the maintenance management system, a communication cable for a network is laid inside the press line with a management computer being the starting point, and a connector capable of being connected to a communicable device is placed in at least one predetermined location on the communication cable. A portable input/output terminal, which is connected to the connector, incorporates software for optionally detecting and displaying maintenance information in the management computer, and which allows an operator to operate the software, is included. In response to a request command for detection and display from the portable input/output terminal, the management computer provides the corresponding information from the maintenance information to the portable input/output terminal

In the die cushion device, a shock absorber device relieves shock between a cushion pad and a support section. The shock absorber device includes a damping section and an elastic section. The damping section generates reaction force in accordance with the relative speed of the cushion pad with respect to the support section. The elastic section generates reaction force in accordance with the relative displacement of the cushion pad with respect to the support section. The controller section controls a servomotor so that a speed difference between the speed of the slide member and the speed of the support section is set to be a predetermined target speed difference value that changes over time.

A touch screen display having a display surface composed of a touch screen, on which screens can be selectively displayed by touching the touch screen in an interactive manner. The touch screen display does not take time in executing a program and ensures high display response performance. A location specified by a touch on the display surface of a plasma display is detected in a touch detecting circuit by detecting a mesh number which is allocated to each of mesh regions into which the whole display surface is divided by a virtual mesh. By a switch filter, when the detected mesh number corresponds to other locations than those of control instruction indicia each displayed in the form of an operation button on the screen displayed on the display surface, the mesh number is invalidated. On the other hand, when the mesh number corresponds to the location of any one of the control instruction indicia, the mesh number is validated. The control instruction indicium selected by a touch is identified by the switch filter for assigning a switch number corresponding to the selected control instruction indicium to the mesh number, whereby a desired screen switching process can be accomplished.
