In a transfer system, at least one of a plurality of process apparatuses is connected to a station as a connected process apparatus. A station control unit controls a transfer device provided in the station through a communication with a process apparatus control unit to load the processing object to the connected process apparatus from the station and to unload the processing object from the connected process apparatus to the station. The station control unit controls the transfer device to begin unloading of the processing object from the connected process apparatus to the station after receiving a signal indicative of a presence of the processing object to be unloaded from the process apparatus control unit.

Transfer system

A process-line-to-process-line transport apparatus transports a transport subject between corresponding two of process lines. A first transport vehicle transports the transport subject in a first process line, and a second transport vehicle transports the transport subject in a second process line. A relay stocking apparatus is placed in a corresponding location, at which the relay stocking apparatus receives the transport subject from one of the first transport vehicle and the second transport vehicle and passes the received transport subject to the other one of the first transport vehicle and the second transport vehicle.

Transport system

A production management system performs progress management of working steps applied on a workpiece in accordance with a working step flow for manufacturing a product. The production management system comprises a comment storing device for storing a comment having contents relating to a specified working step in the working step flow, an address storing device for storing address information relating to an author of the comment, and a transmitting device for, when it is confirmed that the workpiece has arrived at the specified working step, transmitting predetermined information to an address obtained from the address information stored in the address storing device.

Production management system

A controller of a conveyance system efficiently conveys parts. The controller includes an input/output interface receiving data related to the position and loading state of data of each vehicle; receiving carry-in/out requests from each job shop; and outputting carry-in/out instructions to each vehicle. The controller also includes a ROM storing a control program; a RAM storing job shop positional data, carry-in/out requests, vehicle loading state data; and a processing section computing values of a carriage instruction (e.g., origin, destination, carrier to be carried, carrying route) given to each vehicle using the carry-in/out request data from each job shop and the data stored in the RAM based on the program stored in the ROM.

Controller of conveyance system

A semiconductor substrate production control system controlling the production of semiconductor substrates grouped as lots so that a delay of each lot between processing operations does not exceed a time limit within which the amount of deterioration of the substrates exceeds permissible levels when plural types and plural lots of semiconductor substrates are arbitrarily provided in a process requiring consecutive processing operations. A first control unit controls the progress of production of the semiconductor substrates per lot and various processing equipment. Storage stations store the lots. First and second processing equipment implement predetermined processing operations on the lots, and a conveyer conveys the lots between the storage unit and the first and second processing equipment. A reserving unit calculates processing starting and ending times of the first and second processing equipment for each lot scheduled to be conveyed thereto so that the leave-over time of each lot, which is the time during which the lots are between processing operations, is kept within a predetermined time limit so that an amount of deterioration of the lot is within permissible levels. Finally, a setting unit sets the processing conditions for the first and second processing equipment.
