PRODUCTION LINE MANAGEMENT SYSTEM

Carriages 14a to 14e carry workpieces such as automobile bodies through a plurality of work stations So to Sn for processing, e.g. installation of parts or machining. A controller 31 for controlling the work stations has a memory M for storing carriage identification data and automobile body type data. As the carriages move from station to station, carriage identification data are transmitted to the memory M and corresponding body type data are retrieved from a CPU 30 and stored in memory M. As the carriages progress, these data are moved between corresponding storage areas in memory M so that when any carriage arrives at a particular station its transmitted identification data can be compared at 27 with its identification data already stored in memory M and, if agreement is established, corresponding body type data can be transmitted from memory M to the workstation - both for that carriage and the next. In this way, the body in the work station can be processed according to the transmitted ...

... 1,248,069. Manufacturing plant. CINCINNATI MILLING MACHINE CO. 11 Dec., 1968 [15 Dec., 1967], No. 58842/68. Headings B3B, B3C and B3K. [Also in Division G3] A complete manufacturing plant comprises a primary conveyer loop 11 and secondary conveyer branches 12-16 that lead to machining stations 25, 26, 27, 32, 33. A control system, including a computer, a bulk memory bank and a central data source, controls the movements of workpiece carrying pallets around the conveyer and also the operation of the machines. The pallets include non-magnetic slug identifying means that are read by reading heads 39, 44 at the entrance of the branch conveyers from the primary loop 11 and also at the machining stations. The control system allows a queue of pallets to form in each conveyer branch, but after a specified number, any extra pallet that is directed under a primary programme to a "full" branch conveyer is re-directed by an alternative contingency programme to either another machining station to have ...

PRODUCTION MANAGEMENT SYSTEM WITH SIMULTANEOUS MULTIPLE DATATRANSMISSION

A production line for manufacturing automobiles, for example, has a plurality of movable carriages for carry-ing workpieces such as automotive bodies and a plurality of work stations for processing the automotive bodies such as by installing parts thereon or machining them. A controller which controls the work stations to process the automotive bodies has a memory having a plurality of storage areas for storing carriage identification data from the carriages that have arrived at the work stations and automotive body type data about the automotive bodies on the carriages, and also storing carriage identification data transmitted from next carriages to arrive at the work stations and automotive body type data about the automotive bodies carried on the next carriages. When a carriage arrives at a work station, the carriage identification data about the carriage and the next carriage are transmitted from the carriage to the work sta-tion, and the controller transmits the automotive type data about the automotive bodies on the carriage and the next carriage to the work station. The automotive body in the work station can be processed based on the transmitted auto-motive body type data about the automotive body on the car-riage and then the work station can be prepared based on the transmitted automotive body type data about the automotive body on the next carriage for the processing of the next automotive body which is to arrive next at the work station.

Production line management system

Information code for conveying devices on which an item to be processed is placed has the data of the same item to be processed stored as a set in a memory. The information code inputted into a register undergoes tracking corresponding to the conveyance of the item to be processed. Accordingly, by referring to the identification code in the register and the contents of the memory, it is possible to know the data relating to an item to be processed and the position thereof.

DIE MACHINING DNC SYSTEM

PURPOSE: To smoothly execute data transfer between a host computer and an NC machine by providing a rapid data processor between the host and the machine and transferring and storing succeeding machining data to/in the high-speed data processor during the course of arrangement. CONSTITUTION: This system is constituted of NC machines tool 6a to 6d, i.e., machine bodies 5a to 5d, and NC devices 4a to 4d. The host computer is provided with a memory for storing a program, set data, etc., a CRT display device, and so on. Machine numbers for specifying the machines 6a to 6d, machining data and rearrangement data are stored in the memory. The high-speed data processors 3a to 3d are connected to an NC connection unit through a data transmission line 2. Each high-speed data processor is provided with a microprocessor to be an arithmetic unit and memories such as a ROM storing a control program and a RAM for temporarily storing data.

Direct numerical control (DNC) system including one high-speed data processing unit for each NC machine tool

PCT No. PCT/JP92/01451 Sec. 371 Date Jul. 22, 1992 Sec. 102(e) Date Jul. 22, 1993 PCT Filed Nov. 9, 1992 PCT Pub. No. WO93/10944 PCT Pub. Date Jun. 10, 1993.High-speed data processing units are interposed on one-to-one basis between a host computer and each of NC units corresponding to each of NC machine tools. Each of the high-speed data processing units converts data transmitted from the host computer to each of the NC machine tools into NC data, and then inputs the data to each of the NC units, thereby making unnecessary for the NC units and the host computer to convert the data into NC data. Further, each of the high-speed data processing units temporarily stores machining data or the like transmitted from the host computer, thereby enabling each of machine tool bodies to continue its machining operation without being disturbed by the timing of data transmission.

Direct numerical control (DNC) system including one high-speed data processing unit for each NC machine tool

High-speed data processing units are interposed on one-to-one basis between a host computer and each of NC units corresponding to each of NC machine tools. Each of the high-speed data processing units converts data transmitted from the host computer to each of the NC machine tools into NC data, and then inputs the data to each of the NC units, thereby making unnecessary for the NC units and the host computer to convert the data into NC data. Further, each of the high-speed data processing units temporarily stores machining data or the like transmitted from the host computer, thereby enabling each of machine tool bodies to continue its machining operation without being disturbed by the timing of data transmission.

DNC SYSTEM

A high speed data processor (3a to 3d) is disposed between a host computer (1) and the NC apparatus (4a to 4d) of each NC machine tool (6a to 6d). Data transferred from the host computer to each NC machine tool is converted to NC data by each high speed data processor and is then inputted to the NC apparatus. In this way, conversion of the NC data by each NC apparatus and the host computer becomes unnecessary. Machining data transferred from the host computer is stored in each high speed data processor so as to allow the machine tool to continue the machining operation, so that the limit of timing of the data transfer can be eliminated.
