Abstract

PURPOSE:To avoid an error in the captioned controller for an assembly line by reading the assembly data displayed on a displaying means, which moves together with an assembly transport means, converting the data into the assembly parts data, collating this assembly part's data with the data identifying the part taken out from a shelf, and indicating the result. CONSTITUTION:The data 7 on an assembly 1 is displayed on a displaying means 6, which moves together with a transport means 2. The information 7 is read by a reading means 8, and a data file 12 is referred to in order to search for the data on the part 4 to be assembled. The data on the part 4 is then indicated. On the other hand, the worker takes the necessary part 4 out of an accommodating shelf 15 at which an indication lamp is lighted. The data on this part 4 taken out from the shelf 15 is detected by a detecting means 17, and collated with the part data indicated, using a collating means 18. The result of the collation is displayed on a take-out displaying means 19. With this constitution, the take-out check can be automated, while accuracy and efficiency in taking out the correct part can be improved.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention involves holding and sequentially transporting various assemblies so that a worker can take out necessary parts from a large number of parts stored in a parts box. This invention relates to a parts take-out control device that prevents parts from being taken out by mistake from a parts box on an assembly line for assembling the above-mentioned assembled products. (Prior Art) Conventionally, when assembling automobile automatic transmissions, etc., the assembled parts are held and transferred one by one on the assembly line, and workers select the necessary parts from among a large number of parts stored in parts boxes. I am trying to take it out and assemble it into the above assembly. That is, a parts box is provided near the assembly line, and parts to be assembled are classified and stored by type. The worker checked the assembly moving on the assembly line and took out the parts necessary for assembly to the assembly from the parts box. When assembling using the above method, it is difficult to reliably take out the necessary parts from among the many parts in the parts box. Therefore, in order to enable an operator to easily identify which part to take out, a parts removal device is provided in which a display device such as a lamp is provided in the parts box. When a worker takes out the part indicated by the display device, a phototube or area sensor detects this and stops the display on the display device such as the lamp. (Problem to be solved by the invention) However, in the above-mentioned conventional component extraction device,
The operator has to check whether he or she has correctly removed the parts that should be removed, and it is difficult to reliably prevent incorrect assembly of parts. In particular, when there are two or more parts to be taken out from one parts box, it is even more difficult to identify the parts that have been taken out. The present invention solves the problems of the conventional parts take-out apparatus described above, automatically identifies an assembly being transferred on an assembly line, and when a part is incorrectly assembled to the assembly, The purpose of the present invention is to provide a parts extraction control device that displays the information and allows the necessary parts to be selected and assembled without error. (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a transfer means for holding and sequentially transferring an assembly, and a part that is located near the transfer means and is assembled into the assembly. In an assembly line parts take-out control device having a parts box for storing parts, a display means that moves together with the transfer means and displays data specifying the transfer means is provided, and a reading means is provided for reading the data.

The data of each transfer means and the product number data of the assembly corresponding to the transfer means, and the product number data of each assembly and the product number data of the parts corresponding to the assembly can be compared in a data file. Therefore, the part number data of the parts required for assembly can be obtained from the data of the transfer means read by the reading means. On the other hand, a detection means is provided to detect the parts taken out from the parts box by the worker, and it is possible to obtain the part number data of the parts actually taken out. The part number data of the parts required for assembly into the assembly on the assembly line and the part number data of the parts actually taken out are then compared by a matching means, and the results are displayed. (Operation and Effects of the Invention) According to the present invention, configured as described above, the data of the transport means moving on the assembly line is displayed by the display means that moves together with the transport means, and is read by the reading means. The data read by the reading means is converted into part number data of parts necessary for assembly using a data file. On the other hand, a detection means is provided to detect the parts that the worker takes out from the parts box, and it is possible to obtain the part number data of the parts actually taken out, and to assemble them into the assembly on the assembly line. The part number data of the above-mentioned parts required for the process is compared with the part number data of the actually extracted parts by a matching means, and the results are displayed. Therefore, since the check for parts removal is automated, not only does it prevent workers from assembling parts incorrectly, but it also makes it possible to process multiple parts in one place, improving the efficiency of linking work. ．． (Example) Hereinafter, the parts extraction control device of the present invention will be explained in detail with reference to the drawings. Figure 1 is a system diagram of the parts extraction control device of the present invention. The assembly is, for example, an assembly such as an automatic transmission assembly for an automobile, and is transported along an assembly line 3 while being held by a transport means 2 called a J-bar. The assemblies 1 differ depending on the type of automobile, etc., and are transported on the same assembly line 3. The transfer means 2 are arranged on the assembly line 3 at regular intervals, and when a drive means (not shown) drives the assembly line 3 and moves the transfer means, the transfer means 2 are moved to the top of the assembly line 3. The information will be sequentially sent to the location where the person is waiting. In response, the operator selects a component 4 from the parts box 5 according to the type of the assembly 1 and assembles it into the assembly L. Here, the transport stage 2 is provided with a display stage 6 for specifying one of the plurality of transport means. The 1,000-stage display 6 is constructed in the form of a panel, and is fixed to the rond part of the transfer means 2 or the like.

Information 7 such as a bar code is displayed on the surface of the 1,000-stage display 6.
is printed, and this information 7 can be read with a 1,000-step reader 8 consisting of a barcode league or the like. By the way, the parts extraction control device of the present invention is provided with a data file 12 so that data 9 for specifying the transfer stage 2, part number data 10 of the assembly 1, and part number data 11 of the part 4 can be compared. It is possible to check whether the parts 4 to be assembled into the assembly L and the parts 4 actually assembled are the same.

That is, the data file 12 has a correspondence table 13 in which the number of the transfer means 2 corresponds to the product number of the assembly 1 held by the transfer means 2, and the correspondence table 13
It consists of a correspondence table 14 in which the product number of the assembly 1 obtained by the method 1 corresponds to the product number of the component 4 to be assembled to the assembly 1.

Therefore, from the transfer means 20 number read from the display means 6 by the reader 8, it is possible to specify the parts 4 to be assembled into the assembly 1 held by the transfer means 2. That is, as shown in the figure, when the number "03" of the transfer means 2 is specified by the reading means 8, the assembly part number r 20010J can be obtained through the correspondence table 13, and the assembly part number r 20010J can be obtained through the correspondence table 14. Parts part number ro0
8? J. rol3V" can be obtained.

By the way, in the parts box 5, the part number is r00.
Parts 4 other than 8MJ and r013VJ are also accommodated. For example, part number '10020J, ro12
These parts 4 are not necessary in the case of the above assembly l. Therefore, each parts storage shelf 15 of the parts box 5 is
A display lamp 16 is provided in the display device 1, and only the lamp 16 of the component storage shelf 15 in which the necessary components 4 are stored is lit. When the assembly 1 flows on the assembly line 3, the lamp 16 of the storage cell 15 in which the parts 4 necessary for the assembly 1 are stored lights up, so the worker can remove the parts 4 from the storage cell 15. can be taken out and assembled. At that time, in order to check whether the parts taken out are really necessary, a detection means 17 consisting of a phototube or an area sensor is provided for each storage shelf 15.
The detection result of the detection means 17 is shown in a binary number representation having the same number of digits as the number of parts 4. In other words, as in the example above, the part number is ro08MJ
, When only the part 4 of roI3VJ is taken out from the parts box 5, only the digit of the part 4 becomes "l", the other digits become "0", and the binary number "rl001" as shown in the figure is obtained. It will be done. Further, if the operator takes out part 4 by mistake, for example, if he takes out part 4 of ro12YJ without taking out part 4 of r Q13V J, the binary representation will be 'IOIOJ.

Here, in order to indicate the parts 4 that need to be assembled into the assembly l and the parts 4 that are unnecessary, a binary number display having the same number of digits as the number of parts 4 is performed, similar to the above display. In order to check whether the parts 4 as instructed are taken out from the parts box 5, a checking means 18 is provided, and the checking means 18 uses binary numbers to indicate the necessary parts 4 The numerical value is compared with a numerical value expressed in binary notation indicating the detection result of the detection means (7). This comparison is performed by taking the exclusive OR of the two numerical values corresponding to the binoto, and if the exclusive OR becomes rooooJ, it is determined that part 4 has been taken out correctly, and ro 0 0
If it does not become 0J, it is determined that it has been taken out by mistake, and this fact is displayed by the removal status display means 19. By the way, when there are multiple parts 4 that need to be assembled into the assembly 1, if the above verification is performed before the operator takes out all the parts 4, even though no parts were taken out by mistake, The result of exclusive OR may not be r0000J, which may result in a false determination. In order to prevent this misjudgment, as shown in FIG. 2, it is preferable to calculate the bitwise OR of the numerical value of the necessary component 4 and the numerical value indicating the detection result in advance. Then, from the numerical value of the logical sum and the numerical value of the necessary component 4, a bit-based exclusive logical sum is again calculated. That is, FIG. 2(a) shows the case where the part is taken out correctly, and FIG. 2(fb) shows the case where the part is taken out incorrectly.
In the figure, 21 is a binary representation of the part 4 read by the reading means 8 and determined to be necessary; 22
is the numerical value of part 4, which was specified in parts box 5 as necessary,
23 is the value when verification is performed before the operator takes out all the parts 4. In this case, the logical sum of the bits is calculated in advance between the numerical value 21 and the numerical value 23, and the numerical value 2
4 is obtained. Then, the bitwise exclusive OR is calculated again with the number {124 and the above numerical value 22, and the numerical value 2
5 is obtained.

If the detected value 26 and the above-mentioned value 21 are extracted by mistake, the logical sum of the bits is calculated in advance to obtain the value 27, and then the focus is determined using the detected value 27 and the above-mentioned value 22. The exclusive OR of is calculated and the numerical value 28 is obtained. Note that the present invention is not limited to the above embodiments,
Various modifications are possible based on the spirit of the present invention, and these are not excluded from the scope of the present invention.
