Abstract

An object of this invention is to provide efficient operations of a production line for producing finished products by performing working in which a variety of parts are selectively combined with one another during a plurality of processes. A semi-finished product produced in processes (1 and 2) is assigned a product number; parts serving as raw materials, a supplier of the semi-finished product, or a destination of the semi-finished product or part are specified; and these specified data are distributed and transmitted from a higher level system (4) to respective control systems (5, 6, 7 and 8) as planned data to be executed and planned data to be received. The respective systems display the contents of the data thus transmitted on display sections (52, 62, 72 and 82), issue work instructions on the basis of the contents of the data, and output request instructions to the systems (6, 7 and 8) of the supplier side on the basis of the displayed contents or output supply instructions to the destination systems (5, 6 and 7). The system which has received the request instruction outputs a conveyance instruction to the conveyance control system (9) to convey the raw materials to the system which has output the request instruction, while the system which has received the supply instruction outputs a conveyance instruction to the conveyance control system (9) to convey the raw material from the system which has output the supply instruction.

本発明は、 各種部品を複数の工程で選択的に組み合わせる加工を行うことによ り完成品を生産する生産ラインに関し、 特に各工程における加工作業および倉庫 •各工程間の搬送作業を効率よく行うことができる生産システムの具現に関する。  The present invention relates to a production line for producing a finished product by performing a process of selectively combining various components in a plurality of processes, and in particular, efficiently performing a process and a warehouse in each process and a transport operation between processes. The realization of a production system capable of doing so.
1種類の素材から出発して該素材に切削等の機械加工を順次行い製品を完成さ せるような機械加工ラインにおいては図 10に示すような工程表力作成され、 こ れに基づき機械加工ラインは稼働する。 すなわち、 同図には品番 " 1' の製品は 工程 " 1' で機械加工 Αを行い、 工程 " 2' で機械加工 Bを行い、 最後に工程 - 3" で洗浄を行うことにより完成するという具合に、 以下品番 ' 2' 、 "3" 、 In a machining line that starts with one kind of material and sequentially performs machining such as cutting on the material to complete the product, the process force is created as shown in Fig. 10, and based on this, the machining line Works. In other words, the figure shows that the product with the product number "1 '" is completed by machining in step "1", machining B in step "2", and finally cleaning in step-3. In the following, part number '2', "3",
" 4' …の加工手順力示されている。 このように機械加工ラインの場合は複数の 部品を組み合わせて半成品を得るという工程がないため、 各工程における半成品 は出発点となる部品の品番を指示することで足りることになる。 たとえば、 品番"4 '… Machining procedure power is shown. In the case of a machining line, there is no process of combining multiple parts to obtain a semi-finished product. It is enough to instruct.
" I" の製品を作成する工程 - 2- においては 「前工程 - 1- にある品番 " 1" の半成品を自工程 ' 2' に搬送してくる。 」 、 そして 「搬送してきた品番 - 1- の半成品に機械加工 Bを施すことにより品番 - 1" の半成品を作成する。 」 、 そ して 「次工程 ' 3" に品番 " 1' の半成品を搬送する。 」 というように単一部品In the process of creating the product of "I"-2-, "The semi-finished product of the product number" 1 "in the previous process-1- is transported to the own process '2.'", and "The transported product number-1 -The semi-finished product of-is subjected to machining B to produce a semi-finished product of part number-1 ". ”And“ Transfer semi-finished product of part number “1” to the next process '3'. ”
- 1" の品番を示し作業指示を行うことで一連の搬送および加工作業が行われる。 ところで、 自動車の生産ラインのように各種部品を複数の工程で選択的に組み 合わせる加工を行うことにより完成品を生産するものにあっては、 ある工程にお いて前段までの工程で得られた半成品または部品力複数組み合わされて (組立、 溶接等の加工が施されて) 新たな半成品力得られる。 したがって、 上記機械加工 ラインのように最小単位の部品についてのみ品番が付与されていたのでは、 半成 品を、 該半成品を構成する部品の複数の品番で特定するしかない。 このため、 上 記工程表の作成処理が複雑になるとともに、 搬送および加工作業の処理の効率が 損なわれることとなつていた。 -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.
本発明はこうした実情に鑑みてなされたものであり、 各種部品を複数の工程で 選択的に組み合わせる加工を行うことにより完成品を生産する生産ラインを効率 よく稼働するための作業指示装置および搬送制御装置を提供することをその目的 としている。 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.

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
以上のようにして製品種類ごとに分類された部品構成表力2 ί乍成されたならば、 つぎに同構成表に基づき各システム 5〜7ごとに分けた工程設計データ 5 b、 6 b、 7 bを第 5図に示すように作成する処理が行われる。 すなわちメインライン 3用工程設計データ 5 bについていえば、 部品構成表より供給先識別番号の上位 1桁が 3である品番のものを に必要な部品、 半成品として選択する。 これよ りたとえば製品 XX Xに関しては品番 1 2 0 0 1と品番 1 1 0 0 2と品番 0 1 0 0 7が選択される。 これより同図に示すように、品番 1 2 0 0 1の半成品はメイ ンライン 3のステーション 3 1 0に供給され、 品番 1 1 0 0 2の半成品はメィン ライン 3のステーション 3 2 0に供給され、 品香 0 1 0 0 7の部品はメインライ ン 3のステーション 3 3 0に供給され、 これら品番 1 2 0 0 1、 1 1 0 0 2の半 成品と品番 0 1 0 0 7の部品から製品 X X Xを作成するという内容がデータ化さ れる。 ここで製品 X X Xを構成する品番 1 2 0 0 1の半成品は 「部品」 として見 做している。 製品 Υ ΥΥ、 Ζ Ζ Ζ…についても同様にしてデータ化され、 メイン ライン 3用工程設計データ 5 bが作成される。 同様にしてサブライン 2用工程設 計データ 6 bが作成される。 この場合、 まず、 部品構成表より供給先識別番号の 上位 1桁が 2である品番のものが ¾5:に必要な部品、 半成品として選択される。 つぎに、 部品構成表より供給元識別番号が 1 2である品番のものが ¾5:加工され るべき半成品として選択される。 この結果、 たとえば製品 XX Xに関して品番 1 1 0 0 1、 0 1 0 0 3力 s必要な部品、 半成品として選択され、 品番 1 2 0 0 1が 組立加工されるべき半成品として選択される。 製品 ΥΥΥ、 Ζ Ζ Ζ…についても 同様にしてデータ化され、 サブライン 2用工程設計データ 6 b力 乍成される。 以 下、 同様にして同図に示すようにキット場 1用工程設計データ 7 b力 乍成される。 このようにある 1つの工程 (たとえばサブライン 2) における ¾ϊ加工は、 組 立に使用する複数種類の部品および「部品」 と見做された半成品の品番と 1種類 の組み立てられるべき半成品 (製品を含む) の品番で表される。 またある 1つの 工程 (たとえばキッ ト場 1) の半成品 (たとえば品番 1 1001) をつぎの工程 (たとえばサブライン 2) の 「部品」 と見做し、 品番 1 1001で特定するよう にしたので前後工程のつながりを実線矢印のごとく単純に表現することができる。 逆にいえばサブライン 2の品番 1 1001に向けて複数の矢印力接続されること がない。 なお、 異なる の製品間、 たとえば XXX、 YYY間で共通の部品、 半成品を用いる場合は、 たとえば太線矢印に示すように同じ部品の品番 (たとえ ば 1 1001) を用いて記述することができる。 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.
なお、 部品構成表では省略している力 s、 第 5図の工程設計データでは部品の品 番ごとに組立に必要な個数が設定されている。 また、 1種類の半成品を作成する 作業単位ごとに作業に要する時間、 つまりリードタイム L/T (分) を示すリー ドタイムデータ力 s設定されている。 たとえば、 製品 XXXを作成するためのサブ ライン 2用工程設計データ 6 bには、 「部品」 (と見做された半成品) 1100 1力 個と部品 01003が 2個とで半成品 12001をリードタイム 15分で 組立加工すベきであるという情報が付加されている。 以上のような工程設計デー タ 5 b、 6 b、 7 bが作成されると、 これらデータは上位システム 4に入力され る (ステップ 101) 。 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).

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?

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
無人^ 車を使用して部品等を搬送する場合は以下のようにする。 すなわち、 サブライン 2における 順 1を例に取れば、 表示部 6 2の表示内容をみてサブ ラィン管理システム 6におけるキ一ボ一ド等の入力手段により 「品香 1 1 0 0 1、 供給先は 2 1 0」 という要求指令を入力する。 この内容を送信部 6 1から供給元 識別番号 1 1で示されるキット場管理システム 7に対して送信する。 これととも に 「品番 0 1 0 0 3、 供給先は 2 2 0」 という要求指令を入力して、 この内容を 送信部 6 1から供給元識別番号 0 1で示される倉庫管理システム 8に対して送信 する。 すると、 キット場管理システム 7では上記要求指令を受取り、 これに応じ て品番 1 1 0 0 1の半成品を 2 1 0で示されるサブライン 2のステーション 2 1 0に向けて無人搬送車により搬送するための搬送指令を搬送制御装置 9に出力す る。 この結果、 無人搬送車は所要に走行制御され、 品番 1 1 0 0 1の半成品をサ ブライン 2のステーション 2 1 0まで搬送する。食庫管理システム 8でも同様に して要求指令入力に応じて自動倉庫 0から品番 0 1 0 0 3の部品を出庫させ、 無 人 車に載せてサブライン 2のステーション 2 2 0に向けて^!するための出 庫指令および搬送指令を搬送制御装置 9に出力する。 この結果、 自動倉庫 0から 同部品は出庫され、 無人搬送車により同ステーションまで m¾される。 メインラ イン管理システム 5、 キット場管理システム 7でも同様に前段システムに対して 要求指令が出力され、 前段システムは要求指令に応じて搬送制御装置 9に搬送指 令を出力することになる。 この結果、 必要な素材が ¾¾、 的確に後段の工程に搬 送される。  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.
ところで、 オペレータの入力操作を介して要求指令を送信するのではなく、 サ ブライン管理システム 6に実行計画データ 6 a力入力されたならば、 これに基づ き自動的に要求指令を送信するような実施も可能である。  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.
また、 要求指令力5'入力されたシステムでは部品等の在庫があることを前提とし て説明したが、 要求指令力 s入力されるサブライン管理システム 6、 キット場管理 システム 7、 倉庫管理システム 8ではァゥトブットされる部品等をカウントする などして、 数を管理し、 「¾¾あり、 無し」 を示すフラグを設定することが 考えられる。 そして要求指令力 s入力されても 「¾J$無し」 のフラグが立っていれ ば 「拒否」 の内容を要求指令を出力したシステムに送り返すような実施が考えら れる。 また、 搬送指令を搬送制御装置 9に出力し、 搬送が完了した時点で、 「搬 送済み」 という情報を要求指令を出力したシステムに送り返すような実施も可能 である (ステップ 1 0 5 ) 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).
なお、 実施例では組立に必要な部品、 半成品の供給元を各システムごとに表示 するようにした力 これとは逆に加工の終了した半成品 (または自動倉庫にある 部品) の供給先を各システムごとに表示するようにしてもよい。 たとえば、 図 9 の実行計画データ 7 aのキット順 1を例にとれば、 半成品 1 1 0 0 1に対応して 供給先識別番号 2 1 0 (供給先はサブライン 2のステーシヨン 2 1 0 ) がさらに データとして付加されることになる。 よってこのような実行計画データおよび入 庫計画データが各システムに送信されたならば以下のような態様で上記作業指示 および搬送制御を行う。  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.

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.
なお、 実施例のシステムとしてはメイ ン、 サブ、 キット、 自動倉庫の各管理シ ステム 5〜 8がそれぞ M虫立した実行計画データおよび入庫計画デ一タにより稼 働するので、 各管理システム 5〜 8の機能をそれぞれ別個のハードウェアで実現 することができる。 したがって工程の種類や数が異なる様々な生産ラインに容易 に対応することができる。 また生産ラインの構成の変更に柔軟に対応することが できる。 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.
