Carry out final quality inspections and legal compliance inspections at the finished vehicle inspection line, and ship the finished vehicles that pass these inspections to the dealers that have placed the order.

[0003] In the above-mentioned automobile production line, the body information for each automobile including information such as vehicle type, body color, equipment, options, etc. is stored in a host computer called ALC (Assembly Line Control) using the frame number as key information. Based on the input car body information, production management of each production process such as welding, painting, and car body assembly is performed.

[0004] Then, in the car body assembly process of the automobile production line, the finished car, in which all the outfitting has been completed, is sent to the finished car inspection line, and the worker conducts inspections related to quality such as welding, painting, and car body assembly defects. Is called. This inspection result is entered by the operator on the inspection card attached to the finished vehicle. Subsequently, inspections such as legal compliance alignment, side slip, brake speed, emission, etc. are performed, and these measured values are added to the inspection card described above by the operator.

[0005] In the final process of the finished vehicle inspection line, the worker inputs, for example, information related to the inspection results written on the inspection card from a terminal keyboard connected to the ALC. Here, when all the inspection items satisfy the predetermined inspection pass condition, the worker determines that the completed vehicle has passed the inspection, and inputs the information of “OK” for shipment to this terminal. An inspection certificate is issued, and the finished vehicle is shipped to a dealer.

[0006] In the above-described completed vehicle inspection line, a terminal for information on the inspection result in the final process Since the operator has entered the information manually, an input error has occurred, and the finished vehicle that can be shipped is determined to be “failed”. Could be readjusted.

[0007] In order to solve this problem, for example, JP 2002-12177 A (see paragraphs 0009 to 0015, FIG. 1 and FIG. 2) is provided with a barcode in each inspection process of the finished vehicle inspection line. An inspection result management system is disclosed that reduces erroneous input when inputting inspection results to terminals by using labels. More specifically, the inspection procedure in the inspection result management system disclosed here is as follows. First, the measurement values in each inspection process are printed as a bar code and a label, and sequentially printed on the inspection instruction sheet as an inspection card. Affix it. In the final process of the finished vehicle inspection line, the barcode attached to the inspection instruction sheet is read using a barcode reader, and the measurement value of each inspection process is stored in the inspection result data collection PC. Each inspection determination is performed. The inspection results for each inspection process are printed out and the final inspection decision is made.

[0008] However, in the inspection result management system disclosed in JP 2002-12177 A, an operation for attaching a bar-coded label of the result of the operator's inspection to the inspection instruction sheet or an inspection instruction at the final inspection station. Since the label affixed to the vote is read with a bar code reader, human error such as forgetting to attach the label or incorrect label reading may occur.

[0009] Therefore, there is a need for a system and method that can suppress errors that occur in each process in a finished vehicle inspection line of an automobile assembly plant. The present invention has been made in view of the above-described problems of the prior art.

[0028] (Inspection procedure in human inspection process)

Next, the inspection process of the complete vehicle 17 in the complete vehicle inspection line shown in FIG. 1 will be described in detail.

[0029] When the assembly of the completed vehicle 17 is completed in the vehicle body assembly process 13, the completed vehicle printed on the assembly specification sheet (not shown) using the exit barcode reader 13a installed near the exit of the vehicle body assembly process 13 The frame number information is read from the barcode converted from the 17 frame numbers. The read frame number information is transmitted to the production instruction host 1, whereby the production instruction host 1 prints from the printer (not shown) including the bar code converted from the frame number and the inspection items in the human inspection process 14. Output inspection card 6 is output. This inspection card 6 is attached to the complete vehicle 17 on the complete vehicle inspection line and is transferred from the human inspection process 14 to the automatic machine inspection process 15. From body assembly process 13 The finished vehicle 17 sent to the human inspection process 14 is inspected by the worker for quality such as welding, painting, and body assembly by a predetermined inspection method. The operator enters this inspection result on the inspection card 6.

[0030] (Inspection procedure in automatic machine inspection process)

When the inspection in the human inspection process 14 is completed, the completed vehicle 17 and the inspection card 6 are sent from the human inspection process 14 to the automatic machine inspection process 15. Here, FIG. 2 is a flowchart for explaining the operation of the inspection management host 2 in the inspection process of the automatic machine inspection step 15. The operation of the completed vehicle inspection verification system after the automatic machine inspection process 15 will be described with reference to the flowchart shown in FIG.

[0031] First, when the completed vehicle 17 is sent to the automatic machine inspection process 15, the entrance bar code reader 7a attached to the alignment inspection machine 7 installed at the most entrance side of the automatic machine inspection process 15 is used. The barcode obtained by converting the frame number of the finished vehicle 17 printed on the inspection card 6 is read. The read frame number information of the complete vehicle 17 is transmitted to the production instruction host 1 and also to the inspection management host 2. The inspection management host 2 receives the frame number information of the complete vehicle 17 to be inspected. (Step S101).

[0032] The production instruction host 1 that has received the frame number information uses the frame number information as key information to retrieve the body information of the completed vehicle 17 from the stored body information, and the inspection management host 2 Send to. Thereby, the inspection management host 2 receives the vehicle body information corresponding to the frame number of the completed vehicle 17 from the production instruction host 1 (step S102).

[0033] Next, the inspection management host 2 compares the frame number information received from the entrance barcode reader 7a received in step S101 with the frame number information included in the vehicle body information received in step S102. Confirm that they match (step S103). Then, the inspection management host 2 that has received the vehicle body information of the completed vehicle 17 to be inspected stores it in the storage means and searches for the determination reference value information corresponding to the received vehicle body information from the determination reference value information ( Step S 104).

Next, the complete vehicle 17 proceeds to the alignment inspection machine 7 and undergoes alignment inspection. The measurement values measured by the element inspection machine 7 are sent to the inspection management host 2 as measurement value information. Thereby, the inspection management host 2 receives the measurement value information (step S105). [0035] The inspection management host 2 that has received the measurement value information determines whether or not the inspection is acceptable based on the determination reference value information of the complete vehicle 17 searched in step S103, and indicates a determination result that indicates whether the inspection is acceptable. Information is output (step S106), and the measurement value information and the determination result information are stored in the storage means for each complete vehicle 17 in association with the frame number information (step S107).

[0036] Then, the completed vehicle 17 proceeds through the inspection process in the order of the headlight inspection machine 8, the side slip inspection machine 9, the brake / speed inspection machine 10, and the emission inspection machine 11. As the completed vehicle 17 proceeds to each inspection process, first, the completed vehicle 17 printed on the inspection card 6 is checked using the bar code reader (8a, 9a, 10a or 11a) attached to the inspection machine of the inspection process. Read frame number information. The read frame number information is transmitted to the inspection management host 2, whereby the inspection management host 2 receives the frame number information of the completed vehicle 17 that has proceeded to the inspection process (step S108).

[0037] Then, the complete vehicle 17 is subjected to a predetermined inspection by an inspection machine in the inspection process. The measurement value measured by this inspection machine is transmitted to the inspection management host 2 as measurement value information. Thereby, the inspection management host 2 receives the measurement value information of the inspection process (step S109). The inspection management host 2 that has received the measurement value information determines the pass / fail of the inspection based on the determination reference value information of the complete vehicle 17 searched in Step S103, and the determination result information indicating the pass / fail (Step S110), and the measurement value information and the determination result information of the inspection process are stored in the storage means for each completed vehicle 17 in association with the frame number information (step S111).

[0038] Then, through the iterative process of step S112, the steps S108 to S111 are performed by the headlight inspection machine 8, the side slip inspection machine 9, the brake 'speed inspection machine 10 and the emission inspection machine 11, respectively. The same process is performed in each inspection process until the inspection process by the inspection machine is sequentially completed. Thereby, the inspection management host 2 performs determination in each inspection process based on the measurement value information measured in each inspection process, and stores the measurement value information and the determination result information in the storage unit.

[0039] Through the above process, the completed vehicle 17 that has completed each inspection process in the automatic machine inspection process 15 is sent to the human inspection defect adjustment process 18 on the rear stage side and is detected in the human inspection process 14. Corrected defects will be corrected. The completed vehicle 17 that has been corrected is sent to a pass / fail judgment step 12 in which a comprehensive pass / fail judgment is made.

[0040] (Judgment procedure in the pass / fail judgment step)

Next, FIG. 3 is a flowchart for explaining processing procedures in the quality control host 3 and the determination terminal 4 in the pass / fail determination step 12 arranged on the subsequent stage side of the automatic machine inspection step 15. The operation of the completed vehicle inspection pass verification system in the pass / fail determination step 12 will be described with reference to the flowchart shown in FIG.

[0041] First, in the pass / fail judgment process 12 arranged on the rear side of the automatic machine inspection process 15, the operator performs an inspection related to the quality of welding, painting, body assembly, etc. entered in the inspection card 6 in the human inspection process 14. The result is input using the keyboard of the judgment terminal 4 together with the frame number of the completed vehicle 17 as key information. The determination terminal 4 sends the inspection result information and the frame number information in the human inspection process 14 together with the inspection result information to the quality management host 3 (step S201).

[0042] The quality management host 3 that has received this person inspection determination information (step S202) transmits inspection result request information using frame number information included in the person inspection determination information as key information to the inspection management host 2 (step S202). S 203). The inspection management host 2 that has received the inspection request information searches the determination result information associated with the frame number information stored in the storage unit based on the frame number information included in the inspection result request information. Send to quality control host 3.

Having received this judgment result information (step S204), the quality control host 3 receives the judgment result information, which is information on the received inspection result in the automatic machine inspection process 15, and the inspection result in the human inspection process 14 received from the judgment terminal 4. The completed vehicle 17 having the vehicle body information is referred to the human inspection determination information, which is the information of the inspection, and all inspections are performed based on the pass / fail of all inspection items in the human inspection process 14 and the automatic machine inspection process 15. Depending on whether the item has passed or not, comprehensive judgment information including the previous information and frame number information is output (step S205).

[0043] Then, the quality management host 3 transmits the comprehensive determination information on production instructions host 1 (step S206) _o production instruction host 1 having received the comprehensive determination information is stored in a storage unit of production instruction host 1 The vehicle body corresponding to the frame number information included in the comprehensive judgment information This comprehensive determination information is added to the information and stored. If the pass / fail information included in the comprehensive judgment information is acceptable, the production instruction host 1 uses this body information, for example, a dealer terminal that is a terminal installed at the dealer who ordered the completed vehicle 17. 19 (see Fig. 1). As a result, this dealer can confirm that the ordered vehicle 17 that has been ordered has been inspected and can be shipped.

[0044] Furthermore, the quality management host 3 transmits the comprehensive judgment information and the judgment result information received from the inspection management host 2 to the judgment terminal 4 (step S207). Receiving this comprehensive judgment information and judgment result information (Step S208), the judgment terminal 4 responds to the regulations based on the received judgment result information on the display device in accordance with the inspection results of each inspection process in the automatic machine inspection process 15. Output as a screen (step S209).

Here, FIG. 4 shows an example of the legal compliance screen displayed on the display device of the determination terminal 4 at step S 209! /. As shown in Fig. 4, on the legal compliance screen 40, the pass / fail indication of each inspection item in the automatic machine inspection process 15 is displayed as `` P '' or `` F '', improving the visibility of the operator and measuring Since the value is displayed and the operator does not make a judgment, erroneous judgment at the time of the judgment can be prevented.

[0046] In step S209, in addition to the legal compliance screen 40, a display screen is displayed on the display device for confirming the human inspection determination information, which is information on the inspection result of the human inspection process 14 input by the operator. It is also possible.

[0047] Then, the determination terminal 4 determines whether the pass / fail information for all the inspection items included in the received comprehensive determination information is acceptable (step S210), and is included in the comprehensive determination information. If the pass / fail information is acceptable (Yes in step S210), a predetermined “pass certificate” is printed and output from the printer 5 (step S211). This output certificate is attached to the completed vehicle 17 and shipped to a dealer, and is used as a document for certifying that the completed vehicle 17 has passed the inspection.

[0048] If the pass / fail information included in the comprehensive determination information is unacceptable (No in step S210), the process ends. In this case, the finished vehicle 17 is sent to the adjustment line 16 through a predetermined procedure by an operator who has confirmed the failed inspection items with reference to the legal compliance screen 40 shown in FIG. Analysis of inspection items that have been rejected The corresponding adjustment points are adjusted and sent to the finished vehicle inspection line again.

[0049] As described above, according to the present embodiment described above, conventionally measured values and determination result information for each inspection item that have been manually input are sequentially transmitted to the inspection management host using the frame number of the completed vehicle as key information. Since it is transmitted without human intervention, errors that occur in each inspection process can be greatly suppressed. In addition, since the quality control host makes a comprehensive pass / fail judgment on the finished vehicle inspection line, it is possible to prevent the occurrence of errors when shipping a finished vehicle that has failed the inspection.

[0050] As described above, the power of the exemplary embodiments of the present invention has been described. The present invention is not limited to the above-described embodiments, and does not depart from the scope of the present invention as defined in the appended claims. As long as various modifications and changes can be made to this embodiment.

[0051] For example, in the above-described embodiment, the quality management host and the inspection management host are described as separate computers. However, the quality management host and the inspection management host may be implemented by a single computer. . Furthermore, it is possible to provide the production instruction host with the functions of a quality control host and an inspection management host. In the present embodiment, only the frame number information of the completed vehicle read by the entrance bar code reader is transmitted to the production instruction host and the vehicle body information is returned. However, the bar code installed immediately before each inspection machine is used. Each time the frame number is read by one driver, it is also possible to send the frame number information to the production management host and receive the body information. In the above-described embodiment, the frame number of the completed vehicle is converted into a barcode, and the frame number is read in each inspection process using a barcode reader. For example, RFID (Radio Frequency Identification) is used. It is possible to store the frame number information in the tag and use it with a configuration that reads the frame number information with a dedicated reader.
