-A series of transport and processing operations are performed by indicating the product number of "1" and issuing a work instruction. By the way, processing is performed by selectively combining various parts in multiple processes like a car production line. In the case of products that produce products, new semi-finished products can be obtained by combining a plurality of semi-finished products or parts obtained in the previous process in a certain process (by processing such as assembly and welding). Therefore, if a part number is assigned only to a part in the minimum unit as in the above-mentioned machining line, a semi-finished product must be specified by a plurality of part numbers of the parts constituting the semi-finished product. In addition to complicating the process of creating the process chart, the efficiency of the transportation and processing operations was impaired.

The present invention has been made in view of the above circumstances, and the efficiency of a production line for producing finished products is improved by performing a process of selectively combining various parts in a plurality of processes. It is an object of the present invention to provide a work instruction device and a transport control device for operating well.

Hereinafter, embodiments of a production line work instruction device and a transfer control device according to the present invention will be described with reference to the drawings.

In the embodiment, an automobile production line is assumed as the production line. Fig. 2 conceptually shows the line configuration of a production line that produces automobiles. As shown in the figure, various parts, which are the minimum units for producing automobiles, are placed on the production line. Automatic storage 0 where parts are automatically loaded and unloaded by the transfer control device 9, kit parts 1 where the specified parts are sent * m from the automatic storage 0 and these predetermined parts are collectively palletized, A set of parts conveyed from warehouse 0 and parts palletized and conveyed at kit place 1 (this is called a semi-finished product for convenience). 5: Create semi-finished products such as engines by processing and bonding together. Sub-line 2 and parts transported from automated warehouse 0 and semi-finished products palletized in kitting area 1 and semi-finished products processed in sub-line 2 And it is configured from the main line 3 for creating a finished product automobile by doing this. In the embodiment, for the sake of convenience of description, an equal line configuration in which there is one subline 2 is simplified. The automatic warehouse 0, the kit yard 1, the sub-line 2, and the main line 3 are connected to each other by the transport path of an automatic guided vehicle that transports parts and semi-finished products according to the transport command. The traveling of the automatic guided vehicle is controlled by a transfer control device 9 described later with reference to FIG. Kit site 1 has transport vehicle stations 1 1 0, 1 2 0, 1 3 0, and 1 40 according to the parts transferred from automated warehouse 0, and subline 2 is transferred from kit site 1. In accordance with the view of semi-finished products and parts transferred from the automated warehouse 0, there are transporter stations 210, 220, Also, the main line 3 depends on the semi-finished products conveyed from the sub-line 2 and the semi-finished products conveyed from the kit site 1 and the parts conveyed from the automatic warehouse 0 ^! Stations 3 1 0, 3 2 0, 3 3 0 have.

Fig. 1 shows the system configuration of the production line shown in Fig. 2, and it mainly consists of creating the necessary warehousing plan data in the automatic warehouse 0 based on the production plan of the production line, Creates execution plan data for each process required for each process of subline 2 and main line 3 and creates upper system 4 that supervises and controls automatic warehouse 0, kit yard 1, subline 2, and main line 3, and upper system 4. A main line management system 5 that manages the main line 3 based on the contents of the execution plan data, a sub line management system 6 that manages the sub line 2 based on the contents of the execution plan data created by the upper system 4, A kit space management system 7 that manages the kit space 1 based on the contents of the execution plan data created by the upper system 4, and a plan data created by the upper system 4. Automatic warehouse management system 8, which manages the ¾SU, quantity, placement position, etc. of parts in automatic warehouse 0 based on data, sub-line management system 6, kit place management system 7, and commands output from automatic warehouse management system 8. And a transport control device 9 that controls the traveling of the automatic guided vehicle according to the above and controls the entry and exit of the automatic warehouse 0 in response to the entry / exit command output from the automatic warehouse management system 8. I have. Note that the systems 4 to 8 are composed mainly of computers in terms of hardware, and the systems 4 to 8 are wired or wirelessly networked as indicated by solid arrows. That is, the upper system 4 has the transmission unit 41, and transmits the execution plan data to the systems 5 to 7 and the storage plan data to the system 8. The systems 5, 6, and 7 also have transmission units 51, 61, and 71, respectively, and transmit request commands described later to the lower systems. The systems 5, 6, 7, and 8 have display units 52, 62, 72, and 82, respectively, and display the contents of the input execution plan data and storage plan data on the screen. These display units 52, 62, 72, and 82 are attached to the main line 3, the sub line 2, the kit hall 1, and the automatic warehouse 0 so that they can be easily recognized by the operator.

Hereinafter, the processing performed in each of the systems 4 to 8 will be described with reference to the flowchart of FIG. First, the processing contents of the host system 4 will be described.

• Creating a bill of materials

Let's assume that many kinds of automobiles are produced, such as part number XXX, part number YYY, part number ζζζ, etc.

First, part number based on the data related to the part constituting these products to be produced XX - X, Part Upushiron'upushiron'upushiron, are created for each component configuration table force ^s product ¾ showing the flow of parts and semi-finished products constituting the part ΖΖΖ .... Representatively, the flow of parts and semi-finished products that make up part number XXX can be represented as a parts configuration table as shown in Fig. 4 (Fig. 2 shows the supply route in the line). The numbers in parentheses indicate the identification numbers of the stations supplied by the parts or semi-finished product ^s carrier. That is, in the automatic warehouse 0, the component powers s of the product numbers 01001 to 01007 are placed, and based on this, the product of the product number XXX is finally lined out on the main line 3. Here, as is clear from the figure, in kit 1, the power to obtain a semi-finished product by combining the parts of incense 01001 and 01002 'is set. Here, a new part number 11001 is set for this semi-finished product. In the same manner, kit 1 has a part number 11002 for a semi-finished product made by combining parts of part numbers 01004, 01005 and 01006, and sub line 2 has a part number 12001 for a semi-finished product made by combining a semi-finished product of part number 1 1001 and a part of part number 010 03. Are set respectively. Here, the upper two digits of the part and semi-finished product numbers are coded as the places where these parts and semi-finished products are obtained and placed as follows.

01 = Automatic warehouse 0

11 = Kit area 1

12 = Subline 2 (1)

Hereinafter, this number is referred to as a supplier identification number. From this, for example, a semi-finished product with the product number 12001 can be processed at sub-line 2 indicated by 12, and can be obtained.

In addition, the next supply destination for each part and semi-finished product number, that is, the three-digit supply destination identification number for identifying the next process to be processed and its station is set as shown in the brackets in Fig. 4. Is done. Here, the upper one digit number of the three-digit supply destination identification number means the supply destination process in the following correspondence relationship. 1 = kit area 1

2 = subline 2

3 = Main line 3… (2)

For example, a semi-finished product with a part number of 20001 has a supplier identification number of 310, and a semi-finished product with a part number of 20001 is identified by 10 on the main line 3 indicated by 3. Station 310 can be obtained. For other models Y Y Y, Ζ Ζ Ζ, etc., the same parts configuration table as in Fig. 4 is created. • Creation of process design data

If above manner is classified BOM force ² I乍成for each product type, the next process design data 5 were divided into each system 5-7 based on the configuration table b, 6 b, 7b is created as shown in FIG. That is, regarding the process design data 5b for the main line 3, a part number whose upper one digit of the supply destination identification number is 3 is selected from the parts configuration table as a necessary part or a semi-finished part. Thus, for example, with respect to the product XXX, the product number 1 2 0 1, the product number 1 1 0 0 2 and the product number 0 1 0 7 are selected. From this, as shown in the figure, the semi-finished product with part number 1 201 is supplied to station 310 of main line 3, and the semi-finished product of part number 1 100 2 is supplied to station 320 of main line 3. , Incense 0 1 0 7 parts are supplied to the station 3 330 on the main line 3, and these semi-finished products of part numbers 1 2 0 0 1 and 1 0 0 2 and products of part number 0 1 0 7 The content of creating XXX is converted into data. Here, the semi-finished product of product number XXX1 that constitutes product XXX is regarded as a “part”. Products Υ ΥΥ and Ζ Ζ Ζ are also converted into data in the same manner, and process design data 5 b for main line 3 is created. Similarly, process design data 6b for subline 2 is created. In this case, the part number whose first digit of the supplier identification number is 2 is selected from the parts configuration table as parts and semi-finished products required for # 5 :. Next, a part number with a supplier identification number of 12 from the parts configuration table is selected as # 5: semi-finished product to be processed. As a result, for example, with respect to the product XXX, a part number 11001, 01003 force s is selected as a required part or a semi-finished product, and a part number 12002 is selected as a semi-finished product to be assembled. Products データ, Ζ Ζ Ζ, etc. are also converted into data in the same manner, and the process design data for subline 2 is generated 6 b. Less than In the same way, as shown in the figure, the process design data for the kit site 1 is generated by 7 b. In this way, 工程 machining in one process (for example, sub-line 2) includes the number of parts used for assembly and the number of semi-finished products regarded as “parts” and one type of semi-finished product (including products). ). In addition, the semi-finished product (for example, kit No. 1 1001) of one process (for example, kit place 1) is regarded as the “parts” of the next process (for example, subline 2), and specified as part number 1 1001. Can be simply expressed as a solid arrow. Conversely, there are no multiple arrow connections towards subline 2 part number 1 1001. When a common part or semi-finished product is used between different products, for example, between XXX and YYY, it can be described using the same part number (for example, 11001) as shown by a thick arrow.

The force ^s , which is omitted in the parts configuration table, and the number required for assembly are set for each part number in the process design data in FIG. In addition, the lead time data s, which indicates the time required for work, ie, the lead time L / T (minutes), is set for each work unit that creates one type of semi-finished product. For example, the process design data 6b for sub-line 2 to create product XXX includes “parts” (semi-finished products considered to be) 1100 1 force and two parts 01003, and semi-finished products 12001 lead time 15 Information that the assembly should be processed in minutes is added. When the process design data 5b, 6b, and 7b as described above are created, these data are input to the host system 4 (step 101).

• Creating execution plan data

—In addition to the process design data created and entered in step 101, production plan data 4a as shown in FIG. As shown in Fig. 6, the production plan data 4a contains the product names of various types of products to be produced, XXX, YYY, ΖΖΖ ..., and the assembly order that indicates the order in which these products are produced (Fig. 6, 1, 2, 3 ..), The number of pieces (in the embodiment, the number may be simplified to one piece or more), and the data describing the scheduled end time of production of each product. Based on the process design data 5b, 6b, 7b and the production plan data 4a, as shown in Fig. 7, Fig. 8, and Fig. 9, the main line management system 5, sub line management system 6, Toba management system The execution plan data for each 7 is generated 5a, 6a, 7a. That is, as shown in FIG. 7, the execution plan data 5a for the main line is obtained based on the product name shown in the production plan data 4a, the data of the production end time and the process design data 5b. Is done. At this time, although not shown in the figure, the scheduled start time and the scheduled end time are set in the execution plan data 5a for each work unit (indicated by 1, 2, 3,... In the figure). Also, as shown in FIG. 8, the execution plan data 6a for the sub-line is based on the product name shown in the production plan data 4a, its assembly order, its production end scheduled time data, and the process design data 6b. It is done. At this time, based on the lead time data shown in the process design data 6b, each work (in the order of 1 in the figure) should be in time with the scheduled start time of each work shown in the post-process main line execution plan data 5a. , 2, 3…)). Then, a scheduled start time and a scheduled end time are set for each business unit (not shown). In addition, as shown in Fig. 9, the execution plan data 7a for the kit site is based on the product name shown in the production plan data 4a, the data at that time, the estimated production end time, and the process design data 7b. Power is applied. At this time, based on the lead time data shown in the process design data 7b, the scheduled start time of each work shown in the # 1 execution plan data 5a for the main line and the execution plan data 6a for the sub line which is about # 1 In this way, the order of each work (shown in the order of kits 1, 2, 3, ... in the figure) will be determined. Then, a scheduled start time and a scheduled end time are set for each work unit (not shown). Although not shown, as an alternative to the above-mentioned execution plan data for the warehouse management system 8, the plan data is based on the production plan data 4a and the process design data 5b, 6b, 7b. Created. This λ ^ plan data is data indicating the part numbers of the parts to be prepared for assembling all the products shown in the production plan data 4a. For example, the parts required to produce the product XX X are 0 1001 to 01007 (step 102). : If the execution plan data 5a to 7a and the storage plan data are generated as in Lh, the transmission plan 41 sends these execution plan data 5a, 6a, 7a and Main line management system 5 and subline management system 6 Processing for transmitting to the kit place management system 7 and the warehouse management system 8 is performed (step 103).

•Operating instructions

In each of the systems 5 to 8, processing of displaying the contents of each plan data transmitted from the transmission unit 41 on the display units 52 to 82 is performed (step 104). Necessary parts or semi-finished products are arranged for each process, and setup for producing semi-finished products and products XXX, that is, arrangement of tools and jigs to be used, is performed. If subline 2 is taken as an example, the contents shown in Fig. 8 are displayed, so the first operation shown in assembly order 1 is to first replace the semi-finished product with part number 1101 with kit 1 It can be seen that it is sufficient to arrange for transportation from the site 2 and also to transport the parts with the part number 0 1 0 3 from the automatic warehouse 0 indicated by 0 1. Here, as the mode of transporting the parts and semi-finished products as materials, the operator force s based on the display content of the display unit 62 s The semi-finished products (1 1 0 0 1) and the components (0 1 0 3) to be the materials are manually It is conceivable that the wafer is conveyed from the previous step. Such manual transfer of a component or the like is particularly effective when the component equivalent force s is large and cannot be transferred by an automatic guided vehicle. In addition, tools and jigs can be properly arranged in accordance with the material part numbers (11001 and 01003) and the processed part numbers (120001). The above pre-processing is performed quickly and accurately, and the first assembly work is performed. In the following, the assembling order 2, 3, 4, etc. are also sequentially and promptly and accurately performed. Now, has been described main line management system 5 for the sub-line 2,-Kit table示力of in the same way, even door parking management system 7 each content of the transmitted execution plan ^data? Display unit 5 2, 7 2 made at, in this Pre-processing and assembling work will be performed accurately. Such pre-processing and assembly work may be automatically performed based on the transmitted contents. In addition, in the warehouse management system 8, a processing power s is output to output an instruction to the transport control device 9 so as to store necessary parts based on the contents of the storage plan data displayed on the display unit 82. As a result, the automatic warehouse 0 is controlled as required by the transfer control device 9, and necessary parts are stored and placed at a predetermined location in the warehouse. Note that such a λ ^ operation may be automatically performed based on the transmitted contents (step 105). -Transport control

When carrying parts etc. using an unmanned car, do as follows. That is, taking the order 1 in the sub-line 2 as an example, looking at the display contents of the display unit 6 2, by input means such as a keyboard in the sub-line management system 6, “incense 1 1 0 0 1, supply destination is 2 1 0 ”request command. This content is transmitted from the transmitting section 61 to the kit place management system 7 indicated by the supplier identification number 11. At the same time, a request command of “part number 0 1003, supply destination is 220” is input, and this content is transmitted from the transmission unit 61 to the warehouse management system 8 indicated by the supply source identification number 01. To send. Then, the kit place management system 7 receives the above-mentioned request command, and in response to this, transports the semi-finished product of the product number 110001 to the station 210 of the sub-line 2 indicated by 210 by the automatic guided vehicle. Is output to the transport control device 9. As a result, the automatic guided vehicle is controlled to travel as required, and transports the semi-finished product having the product number of 1101 to the station 210 of the sub-line 2. Similarly, in the garage management system 8, parts of the part number 01003 are unloaded from the automated warehouse 0 in response to the input of the request command, placed on an unmanned vehicle, and directed to the subline 2 station 222! A transfer command and a transfer command for the transfer are output to the transfer control device 9. As a result, the parts are unloaded from the automated warehouse 0 and transported to the station by an automated guided vehicle. Similarly, in the main line management system 5 and the kit place management system 7, a request command is output to the upstream system, and the upstream system outputs a transport instruction to the transport control device 9 in response to the request command. As a result, the necessary materials are transported to the subsequent process accurately and accurately.

By the way, instead of transmitting a request command via the input operation of the operator, if the execution plan data 6a is input to the sub-line management system 6, the request command is automatically transmitted based on this. Implementation is also possible.

Also, the explanation has been given on the assumption that there is a stock of parts, etc. in the system where the required command force ⁵ 'is input.However, in the subline management system 6, the kit place management system 7, and the warehouse management system 8 where the required command force s is input, It is conceivable to manage the number by counting the number of parts to be printed, etc., and to set a flag that indicates “with or without a mark”. And even if the required command force s is input, the "¾J $ no" flag is set For example, it is conceivable to send the contents of "rejection" back to the system that issued the request command. Further, it is also possible to output a transfer command to the transfer control device 9 and, when the transfer is completed, send back the information “transported” to the system that output the request command (step 105).

In the embodiment, the source of parts and semi-finished products required for assembly is displayed for each system. Conversely, the supply destination of semi-finished products (or parts in automated warehouses) that have been processed is determined for each system. It may be displayed every time. For example, taking the kit order 1 of the execution plan data 7a in Fig. 9 as an example, the supply destination identification number 2 1 0 (the supply destination is the station 2 210 of the subline 2) corresponding to the semi-finished product 1 100 1 It will be added as data. Therefore, if such execution plan data and storage plan data are transmitted to each system, the above work instruction and transport control are performed in the following manner.

'Operating instructions

For example, when the assembling force of the semi-finished product (1101) is completed in the kit hall 1, the supply destination (2110) of the semifinished product is recognized by looking at the display content of the display unit 62. Arrange to supply semi-finished products to this supplier. The same applies to Mainline 3, Subline 2, and Automatic Warehouse 0.

• Transport control

For example, when the assembly of the semi-finished product (1101) is completed in the kit hall 1, the supply destination (2110) of the semifinished product is recognized by looking at the display content of the display unit 62. Then, a supply command is output to the supply destination indicating that the semi-finished product is in the “suppliable state”. In response to this command, a transfer command is output to the feed control device 9 so that the semi-finished product can be transferred from the kit site 1 where the command was output to the feed control unit 9 when the power (sub-line) of the supply destination becomes necessary. The same applies to main line 3, sub line 2, and automatic warehouse 0. In addition, the contents of the execution plan data 5a to 7 and the storage plan data of the embodiment are merely examples, and in order to quickly and accurately perform a series of operations such as preprocessing, assembly work, and storage of parts, the above-described processing is performed. It is also possible to add information such as product names (parts and semi-finished products) and jigs to the data.

The system of this embodiment includes main, sub, kit, and automatic warehouse management systems. Since each of the systems 5 to 8 operates based on the execution plan data and the stocking plan data, the functions of the management systems 5 to 8 can be realized by separate hardware. Therefore, it can easily cope with various production lines having different types and numbers of processes. In addition, it can flexibly respond to changes in the configuration of the production line.

The present invention is not limited to automobile production lines, but can be applied to a wide variety of production lines, such as 部品 5: processes, welding processes, etc., in which various parts are selectively combined in multiple processes. It is.

Industrial applicability

Lb As described above, according to the present invention, the semi-finished products generated at each stage of the process are specified by the product number, the supply source of the parts and semi-finished products to be used in each process and the warehouse, and the supply destination of the semi-finished products to be created The part delivery destination) is specified by a code, and the specified data is distributed to each process and warehouse and sent to each process and warehouse as plan data. Based on this, work instructions and transfer control are performed, so that a series of work forces such as transfer and processing can be performed accurately. As a result, the production efficiency of the production line is greatly improved.
