Abstract

A processing facility includes transport management means for managing a transport vehicle which transports a processing target object by traveling along a transporting route which extends along a plurality of processing devices and a storage device for storing the processing target objects. The transport managing means: monitors process advancement information which is transmitted from the processing device to the primary managing means; selects, as advance transport origin and before the transport command information is transmitted from the primary managing means, a processing device, among the plurality of processing devices, in which a process performed on the processing target object has been completed, or is nearly completed; and performs advance transport control in which the transport vehicle is caused to travel to the processing device selected as the advance transport origin in order to carry out the processing target object from the processing device.

First claim

The invention claimed is:

1. A processing facility comprising:
a transport vehicle which transports a processing target object by traveling along a transporting route which extends along a plurality of processing devices for performing processes of different steps on processing target objects and a storage device for storing the processing target objects,
wherein each of the plurality of processing devices is configured to transmit, to primary managing means, process advancement information which includes carry-in request information for requesting a processing target object to be carried in and carry-out request information for requesting a processing target object to be carried out,
wherein when the carry-in request information and the carry-out request information are transmitted, the primary managing means is configured to generate transport command information which indicates a transport origin and a transport destination for the processing target object and to transmit the transport command information to transport managing means,
wherein the transport managing means is configured to control traveling of the transport vehicle based on the transport command information, and
wherein the transport managing means is configured: to monitor the process advancement information which is transmitted from the processing device to the primary managing means; to select, as an advance transport origin and before the transport command information is transmitted from the primary managing means, a processing device, among the plurality of processing devices, in which a process performed on the processing target object has been completed, or is nearly completed; and to perform advance transport control in which the transport vehicle is caused to travel to the processing device selected as the advance transport origin.

2. The processing facility as defined in claim 1 , wherein the transport managing means is configured to select, as the advance transport origin, a processing device in which the process performed on the processing target object has been completed, based on the carry-out request information which functions as the process advancement information.

3. The processing facility as defined in claim 1 , wherein the plurality of processing devices are configured to transmit, to the primary managing means, process progress information for the processing target objects as the process advancement information, and wherein the transport managing means is configured to select, as the advance transport origin, the processing device in which a process performed on the processing target object is nearly completed based on the process progress information which functions as the process advancement information.

4. The processing facility as defined in claim 3 , wherein the transport managing means is configured: to designate a processing device, for which a progress status of the process performed on the processing target object is a predetermined progress status that occurs before completion of the process, as the processing device in which the process performed on the processing target object is nearly completed; and to select the processing device as the advance transport origin.
