[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a production control method used in automobile production lines, etc., and particularly to production (here, production refers to processing, assembly, inspection, etc.) This article relates to a production management method that creates production history information based on the content, stores it in memory, and uses it for after-sales management, etc. (Prior Art) As an example of a production control method conventionally used on an automobile production line, there is a method carried out by a production history production machine shown in Fig. 3. This production history creation device includes a plurality of reading means 2 which are installed in each part of the production line and store information such as the type of parts and production information to be attached to a predetermined product on the production line in a magnetic card 1; A plurality of magnetic card readers 3 provided in each part and into which the magnetic card 1 is inserted to read out information stored in the magnetic card 1; and a history management file 4 which stores production history information obtained based on production information; An operator console 5 in which various operation switches are arranged and outputs a predetermined signal by operating the switches; the reading means 2; a magnetic card reader 3; and a history management file 4.
and a host computer 6 that is connected to the operator console 5 and controls each part according to a preset program. For example, when a specific part has been installed, information to that effect is stored in the magnetic card 1 using the reading means 2. This magnetic card 1 is affixed to a product and transported together with the product, and is useful for work management in the process.
The information is also read by the magnetic card reader 3 at a predetermined production stage. This read information is stored in the history management file 4 as production history information and is useful for after-sales management. For example, if it is discovered that there is a defective part in the product while it is flowing on the production line, the magnetic card 1 can be read by the magnetic card reader 2 and the production history information and defect situation can be compared. It looks like this. Furthermore, if a defect is discovered in a shipped product, the operator can operate the operator console 5 to read production history information from the history management file 4 and perform after-sales management of the product. By the way, in the above-mentioned production control method, when writing or reading data to or from a magnetic card, the magnetic card must be removed from the product or the product mounting member each time and reattached, which takes a lot of time, and The problem was that it was easy to make mistakes. In contrast, so-called I
A mobile communication device called a D-plate is attached to the workpiece, and multiple fixed communication devices that can send and receive data to and from this mobile communication device are installed along the production line, and a host computer is connected to these fixed communication devices to write data and One possibility is to read the data. (Problems to be solved by the invention) However, this method had the following problems. (1) When the production line is operating, a large amount of production history information may be input to the host computer at the same time, and in such a case, there is a risk that a communication waiting state may occur. In addition, to avoid this problem, it is possible to avoid inputting data in parallel and instead of real-time processing, it is possible to summarize the data and input it after that. However, in this case, there was a problem that the production point was unclear. (2) Only the production processing details were used, and if a defect occurred, it was difficult to identify the circumstances and cause of the defect. The present invention was made to solve the above-mentioned problems, and can easily write and read production history information.
The purpose of the present invention is to provide a production control method that is useful for after-sales management by being able to accurately identify the point of production for a product without creating a waiting state for communication. (Means for Solving the Problems) In order to achieve the above object, the present invention provides production history information along with production time on an ID plate that is provided on a product conveyance means in which a jig for conveying the product circulates and is conveyed together with the product. As the product is moved to another product transport means, the stored information is copied to the ID plate of the other product transport means, and after the production of Saikizuna is completed, the stored information is input into the host computer. It is characterized by (Function) With the above configuration, the present invention stores production history information indicating the production content on the ID plate that is transported along with the product on the production line, and the information in parentheses can be input to the host computer and read out. Writing of production history information ●Reading is easy, and since the stored information is input to the host computer from the ID7' rate of the final product transport means, simultaneous input of production history information can be avoided and a waiting state for communication occurs. There is no. Furthermore, since production time information is added to the production history information and stored, it is input to the post computer in a chronologically organized form. As a result, the host computer can store data in its original form, and by reading the stored data from the host computer, it is possible to reliably identify the point of production for a product, which is useful for after-sales management. (Example) A production control method according to an example of the present invention will be explained below with reference to the drawings. Figure 1 shows an automobile engine production line and its production control system on which this production control method is implemented. In the figure, the production line IO is the conveyor 1 for the pre-assembly process.
1. Consists of a conveyor 12 for the middle assembly process, a conveyor 13 for the post-assembly process, and a conveyor 14 for the inspection process. The engine 15 is mounted on a pallet jig 16 and transported by each conveyor 11, 12, 13, and 14. The engine 15 also moves from the conveyor 11 to the conveyor l2, and from the conveyor l2 to the conveyor l2.
From conveyor 13 to conveyor 13, and from conveyor 13 to conveyor 14. An ID plate 17 equipped with a transmitting/receiving means and a memory is attached to the pallet jig l6 of each conveyor 11, 12, 13, 14. In addition, each conveyor 11.
l2. 13 and 14 are provided with a controller 22, which will be described later. These controllers 22 have an ID plate l.
The fixed side I Dfill, which can be held and pressed, consists of an antenna 18 and an antenna control unit 19 so as to be able to transmit and receive data to and from the antenna 7.
20 are now connected. Also conveyor 1
1.12, near conveyor 12.13, and conveyor 13. A controller 33, which will be described later, is provided near each of the controllers 14. The controller 33 is connected to the fixed ID section 20, and is capable of writing data from the ID play 17 of one conveyor to the ID play 17 of the other conveyor via the fixed ID section 20. .. In the vicinity of each process 11, 12, 13. .) 2l is provided. Assembly equipment 2
Each conveyor 11, 12, 13 .
14 is provided with a limit switch 21a. A controller 22 is connected to the assembly equipment 21 and the limit switch 21a. The controller 22 is assembled with standard data such as design @2
1 to operate the assembly equipment 2l to perform production processing for the engine 15, and input analog data (for example, tightening torque value) from the assembly equipment i21 and store it in the memory 23. Compare the data and standard data and use the fixed side ID to determine whether the data corresponds to the production history information.
It includes an arithmetic unit 22a that outputs an output to the unit 20, and a timer 24. When the analog data is input, the controller 22 inputs this time from the timer 24, adds it to the determination result as the production time, and outputs it. A production serial number stamping machine 25 is provided near the front assembly conveyor 11, and stamps a production serial number on the engine 15 before being carried into the front assembly conveyor 11. .. Further, the controller 22 of the conveyor 11 is connected to the production serial number stamp 41 2 5, and the stamped production serial number information is output to the controller 22. An antenna 26 and an antenna control unit 27 for receiving information from the ID plate l7 are provided near the inspection conveyor l4. A host computer 28 is connected to the antenna control section 27. host computer 28
a memory 29 that stores information received by the antenna 26;
keyboard 30, display 31, and keyboard 3
A controller 3 reads stored information from the memory 29 in response to an operation signal of 0 and displays it on a display 3l.
It consists of 2 and. The production control method implemented in the production control system configured as described above will be explained below. tr, before the engine 15 is conveyed to the pre-assembly conveyor 11, a production serial number is stamped on the engine 15 by the production serial number stamping machine 25. This production serial number information is for controller 2.
It is stored in the memory 23 of 2. When the engine 15 is carried onto the pre-assembly conveyor 1l and reaches the limit switch 21a, a detection signal is sent from the limit switch 21a to the controller 22. The calculation unit 22a of the controller 22 is connected to the memory 2.
The production serial number information is read from 3 and sent to the fixed side ID section 20. The fixed side ID section 20 transmits this production serial number information to the ID playback 17 using electromagnetic waves and stores it as shown in FIG. Further, upon receiving a detection signal from the limit switch 21a, the controller 22 operates the assembly equipment 2l on the conveyor 11. Then, pre-assembly processing is performed on the engine 15 using the assembly setup @21. This processed data is input to the calculation section 22a. When the processing section 22a receives this processing data, it inputs production time information from the timer 24. Further, the calculation unit 22a stores the processed data in the memory 23, compares it with reference data, and sends the determination result and the production time information to the fixed ID unit 20. The fixed side ID unit 20 transmits the determination result and production time information to the ID plate 17,
These data are stored in correspondence with production serial number information (see Figure 2). Note that the determination result stored in the ID plate 17 indicates the production history for the engine 15 by the assembly installation Illll2l, and corresponds to the production history information of the present invention. In addition, since this judgment result indicates whether or not it matches the reference data, the amount of information is small, and as a result, even if there are a large number of assembly equipment 21 for production processing on the conveyor l1, or Even if there is a large amount of processing information for assembly setup@21, it can be stored in ID play}17 with plenty of room. For example, some nutrunners have up to 20 axes, and the production processing information for these nutrunners is enormous, and if things continue as they are, I
Although there may be cases where the storage capacity of the D plate is insufficient, by using the determination result, it becomes possible to store information on the ID plate 17 with plenty of room. - After performing the pre-assembly process as described above and completing the production process for the engine 15 on the conveyor 11, the engine l5 is mounted on the pallet jig l6 of the middle assembly conveyor l2.
It will be transferred to. During this transfer, the I of the pre-assembly conveyor 11
The stored data such as the production serial number, production time information, and determination result are transmitted from the D plate 17 to the fixed side ID section 20. Then, the fixed side ID section 20 transmits the transmitted data under the control of the controller 33 to the ID plate 17 of the middle assembly conveyor 12, and the ID plate 17 of the front assembly conveyor 11.
Data is written from the D plate 17 to the ID plate 17 of the middle assembly conveyor 12. Hereinafter, production processing will be performed on the middle assembly conveyor 12, the post-assembly conveyor 13, and the inspection conveyor 14 in the same manner as the processing on the pre-assembly conveyor 11 described above, and the judgment results corresponding to the production history and The production time information is stored in the corresponding ID plate 17, and the stored data and the data transferred from the ID plate 17 of the previous conveyor are written in the ID plate 17 of the next conveyor. After such processing, the pallet jig 16 on which the engine l5 is mounted is transferred to the inspection conveyor l4.
When the pallet jig 16 reaches the conveyance end, the ID plate 17 of the pallet jig 16 transmits stored data such as production serial number, judgment result, production time information, etc. to the antenna 26. Then, the antenna control section 27 sends this information to the controller 32 of the host computer 28. The controller 32 stores this information in the memory 29. When the keyboard 30 is operated as necessary to input a memory address, etc., the controller 32 reads out the corresponding production serial number, judgment result, production time information, etc. from the memory 29, and displays this on the display 3l. .. This display allows you to immediately know whether all judgment results are good or not. Furthermore, if there is an undesirable judgment result, the situation and cause of the defect can be easily identified by referring to the production time information. In this case, this identification can be made more reliable by referring to the production serial number. Note that in this embodiment, a handy type fixed side ID section 20 is used.
The ID plate 17 can be easily repositioned depending on the conveyance status of the ID plate 17, which allows highly accurate transmission and reception. (Effects of the Invention) As explained above, the present invention stores production history information indicating the production content on the production line in the ID plate and inputs this information into the host computer. It is easy to read out, and all production history information is input to the host computer from the 10 plates in the final process, so simultaneous input is avoided and there is no waiting state for communication.Furthermore, the production history information includes the production time. Since information is added, it is possible to easily identify the point in time of production processing for a product, which in turn has the effect of helping to identify the circumstances in which defects occur and their causes.
