  • Patent number: 9696711
    Abstract: A processing indicating device to improve the efficiency of processing on an object. The device includes a first communication unit which communicates information with a plurality of processing devices for processing the object and a second communication unit which communicates information with a conveyance controlling device controlling conveying of the object to the plurality of processing devices. An arrival time predicting unit predicts on the basis of information received by the second communication unit, the time when the conveying device arrives at one of the processing devices. In addition, a finish time predicting unit receives information and predicts the time when the processing on the object in the one processing device finishes. A processing indicating unit causes processing control information that orders the execution of device state improvement treatment to be transmitted to the one processing device on the basis of the predicted respective times.

  • Patent number: 8025473
    Abstract: A carrying system 1 has a carrying path which is laid out in such a manner as to pass through the lower sides of loading table 11 and the like provided at the front face side of treating devices 10, 100, 200, and covered by a cover 5. As the carrying path is positioned below the loading tables, the occupying areas of the loading table 11 and the like and portions of the region of the carrying path are shared so that space saving is achieved, and the accessibility to the treating device 10, 100 or the like from the front side thereof is improved, thereby realizing a layout which facilitates maintenance. A loading surface 11d or the like of the loading table 11 is set to a height which allows a conventional overhead-type carrying system 2 and unmanned carrying vehicle 3 of a floor-type carrying system to load an object on the loading surface, thereby ensuring the co-existence with the other carrying systems.
