Abstract

<P>PROBLEM TO BE SOLVED: To provide a ranking correction system for a high-mix low-volume production line for rearranging workpieces in the priority order of conveyance, and for, when any candidate workpiece is absent, conveying the empty workpiece, and for preventing the line stop of the next process. <P>SOLUTION: This ranking correction system is provided with a reading means for reading the specification information of a workpiece conveyed from the previous process and a control programmable logic controller for storing the workpiece conveyed from the previous process in a storage until the conveyance is decided, and for conveying the workpiece to the next process according to the determined optical ranking. The control program logic controller rearranges the workpieces to be conveyed in the storage in a preliminarily set priority order based on the reading information, and determines whether or not the workpiece in the highest priority is conveyable, and when determining that the workpiece is conveyable, selects the workpiece as the workpiece to be conveyed the next, and when determining that the workpiece is not conveyable, selects the workpiece by repeatedly determining whether or not the workpiece is conveyable in the priority order, and when determining that there is no workpiece to be conveyed the next in the storage, outputs an empty workpiece. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

この発明は多品種少量生産の生産ラインにおいて、下流工程に搬出させるワークの最適な序列を決定することができる多品種少量生産ラインの序列修正システムに関するものである。   The present invention relates to an order correction system for a high-mix low-volume production line that can determine an optimal rank of workpieces to be transported to a downstream process in a high-mix low-volume production line.

従来技術として、ストレージレーンの先頭ワークを候補とし、次工程に搬出させるワークの間隔を考慮して順列を修正することにより、次工程での作業負荷の平準化を図るようにしたペインティッドボディ・ストレージの順列修正システムが知られている（例えば、特許文献１参照）。   As a conventional technology, a painted body that is designed to level the workload in the next process by correcting the permutation in consideration of the interval of the work to be carried out to the next process as a candidate for the first work in the storage lane A storage permutation correction system is known (see, for example, Patent Document 1).

特開平６−１４４３１９号公報JP-A-6-144319

しかしながら、従来のペインティッドボディ・ストレージの順列修正システムでは、次工程へ搬出するワークの候補がストレージレーンの先頭ワークのみであるため、候補ワークが少なく、最適な搬出候補のワークを決定できないという課題がある。また、指定した間隔通りに搬出させるワークが候補内に存在しなかった場合、ワークを搬出することが出来ず、次工程のライン停止につながる恐れがあった。   However, in the conventional painted body storage permutation correction system, the work candidate to be carried out to the next process is only the first work in the storage lane, so the number of candidate work pieces is small and the optimum work candidate for carrying out cannot be determined. There is. In addition, if there is no work to be carried out at the specified interval in the candidate, the work cannot be carried out, which may lead to a line stop in the next process.

この発明は、上記の課題を解決するためになされたもので、搬出候補のワークをレーン先頭に限らずに、ストレージ内の全ワークを候補とし、これらのワークの搬出優先順位を予め設定して優先順にワークを並べ換え、万が一候補となるワークが存在しない場合でも、空ワークを搬出することにより、次工程のライン停止を防止するようにした多品種少量生産ラインの序列修正システムを提供するものである。   The present invention has been made to solve the above-described problem. The work to be carried out is not limited to the top of the lane, and all works in the storage are set as candidates, and the carry-out priority of these works is set in advance. This system provides an order correction system for high-mix, low-volume production lines that rearranges workpieces in priority order and prevents line stoppage in the next process by unloading empty workpieces even if there is no candidate workpiece. is there.

この発明に係る多品種少量生産ラインの序列修正システムにおいては、前工程から搬送されたワークをストレージ内に搬入する前の入り口で、該ワークの型式、オプション等の仕様情報を読み取る読取手段と、読取手段の読み取り情報を記憶し、前工程から搬送されたワークを搬出が決定されるまでストレージ内に格納するとともに、最適な序列に決定して次工程へ搬出する制御プログラマブル・ロジックコントローラとを備え、制御プログラマブル・ロジックコントローラは、読取手段の読み取り情報を基にストレージ内で搬出可能なワークを予め設定された優先順に並び替え、その最優先のワークが搬出可能かを判断し、可能な場合は次搬出ワークとして選択し、搬出不可の場合は優先順に該当ワークが搬出可能かの判断を繰り返すことにより選択し、次に搬出可能なワークがストレージ内に１台も無い時は、空ワークを出すものである。   In the order correction system of the high-mix low-volume production line according to the present invention, at the entrance before the work conveyed from the previous process is carried into the storage, reading means for reading the specification information such as the type and options of the work, It has a control programmable logic controller that stores the reading information of the reading means, stores the work conveyed from the previous process in the storage until it is decided to carry it out, decides the optimum order and carries it to the next process The control programmable logic controller sorts the work that can be carried out in the storage based on the reading information of the reading means in the preset priority order, determines whether the highest priority work can be carried out, and if possible Select as the next unloading work, and if it is not possible to unload, repeat the determination of whether the corresponding work can be unloaded in priority order More select, when the next available carry-out work there is no one in the storage are those that give the sky work.

この発明によれば、次工程への搬出対象ワークが存在しなかった時に、空ワークを出すようにしたので、次工程での全生産ラインの停止を防ぐことができる。通常の生産ラインでは連続してワークが流れるため、１箇所でも停止すれば、全生産ラインが停止する。よって、搬出対象ワークが存在しなかった場合、次工程の全生産ラインが停止するが、この発明により対象ワークが存在しない場合に空ワークを搬出させることにより、生産ラインの停止を防ぎ、工場の稼働率を向上させることができる。   According to the present invention, when there is no work to be carried out to the next process, the empty work is taken out, so that the stop of all the production lines in the next process can be prevented. Since the work flows continuously in the normal production line, if one stop is performed, the entire production line is stopped. Therefore, when there is no work to be carried out, the entire production line in the next process is stopped, but by this invention, when the target work does not exist, the empty work is carried out to prevent the production line from being stopped. The operating rate can be improved.

FIG. 1 is a system configuration diagram showing the configuration of an order correction system for a high-mix low-volume production line according to Embodiment 1 of the present invention, and FIG. 2 shows the operation of the system for correcting a high-mix low-volume production line order according to Embodiment 1 of the present invention. It is a flowchart for demonstrating.

この発明による多品種少量の生産ラインにおいては、前工程から搬送されたワークを最適な序列に並び替えて、次工程に搬出するものである。図１において、先ず前工程から搬送されるワーク１ａは、ストレージ６内に搬入する前にそのワークの型式、オプション等の基本的な仕様情報を読取装置３により読み取られる。そして、読み取られた基本仕様情報は、制御プログラマブル・ロジックコントローラ（以下ＰＬＣという）４に記憶され、照会端末５に表示される。また、搬送されたワーク１ａはストレージ６内に順次格納される。ストレージ６内に格納されたワーク１ｂは、搬出が決定されるまでストレージ６内に保管される。そして、次工程の作業が平準化されるように、照会端末５で設定された情報を基に制御ＰＬＣ４はストレージ６内のワーク１ｂの中から搬出すべき候補のワークを選択する。搬出候補のワークはストレージ６内のどのワーク１ｂからも選択することができる。選択された搬出候補のワークはストレージ６内から搬出され、次工程に搬送される。１ｃは次工程へ搬出されたワークを示している。なお、搬出候補のワークをストレージ６内の全てのワーク１ｂを対象としており、これらのワーク１ｂの搬出優先順位を照会端末５で予め設定しておき、優先順にワーク１ｂを並べ替える。そして、その先頭ワークから、次に搬出可能かを判断し、可能な場合は次搬送ワークとして決定される。搬出不可の場合は、優先の順に該当ワークが搬出可能かの判断を繰り返すことにより選択する。このように優先順位の先頭から搬出可能の判断をすることにより、選択対象ワーク数が膨大に増えたとしても、その中から次に搬出すべき最適なワークを選択することができる。
また、次に搬出させるワークがストレージ６内に無い場合は、空ワーク２を搬出させる。空ワークとは実際にはワークが搬出させないが、論理的にワークを搬出させることにより、連続してワークを搬出させることができ、次工程でワーク無しによる生産ラインの停止を防ぐことができる。万が一、次に搬出可能なワークがストレージ６内に１台も無い時は、空ワークを出す。この空ワークは実際にはワークを搬出しないが、論理上はワークを搬出させることにより、序列内に１台の空きを作る。これにより、次に搬出可能なワークが工程内に無い場合でも、次工程ラインを停止することが無く生産を継続することができる。 In the multi-product and small-quantity production line according to the present invention, the workpieces transferred from the previous process are rearranged in an optimal order and are transferred to the next process. In FIG. 1, first, a workpiece 1 a conveyed from the previous process is read by the reading device 3 with basic specification information such as the type and options of the workpiece before being carried into the storage 6. The read basic specification information is stored in a control programmable logic controller (hereinafter referred to as PLC) 4 and displayed on the inquiry terminal 5. Further, the conveyed work 1 a is sequentially stored in the storage 6. The work 1b stored in the storage 6 is stored in the storage 6 until it is decided to carry out. Then, the control PLC 4 selects a candidate work to be carried out from the work 1b in the storage 6 based on the information set in the inquiry terminal 5 so that the work in the next process is leveled. The work to be carried out can be selected from any work 1b in the storage 6. The selected unloading candidate workpiece is unloaded from the storage 6 and transferred to the next process. 1c has shown the workpiece | work carried out to the following process. It should be noted that the workpieces to be carried out are all the workpieces 1b in the storage 6, and the carry-out priority of these workpieces 1b is set in advance by the inquiry terminal 5, and the workpieces 1b are rearranged in the priority order. Then, it is determined whether or not the next work can be carried out from the leading work, and if possible, it is determined as the next transport work. If unloading is not possible, selection is made by repeating the determination of whether the workpiece can be unloaded in order of priority. As described above, by determining whether or not the work can be carried out from the top of the priority order, even if the number of work pieces to be selected increases enormously, an optimum work to be carried out next can be selected.
If there is no work to be carried out next in the storage 6, the empty work 2 is carried out. An empty workpiece is not actually unloaded, but by unloading the workpiece logically, the workpiece can be unloaded continuously and the stop of the production line due to no workpiece can be prevented in the next process. If there is no work in the storage 6 that can be carried out next, an empty work is taken out. This empty work does not actually carry out the work, but logically, one work is created in the rank by causing the work to be carried out. As a result, even when there is no work that can be carried out next time, the production can be continued without stopping the next process line.

次に、実施の形態１の搬出ワーク決定処理の流れについて、図２により説明する。
先ず、ステップ１０ａでは強制的に空ワークを搬出させる設定指示があるか否かを確認する。空ワーク搬出の設定指示がある場合は、ステップ１０ｆにて空ワークを次搬出ワークとして決定し、処理を終了する。次に、ステップＳ１０ａで空ワーク搬出の設定支持がない場合は、ステップ１０ｂに進みストレージ６内で搬出可能なワークを予め設定された優先順に並び替える。優先順に並び替えることにより、選択対象ワーク数が多くなっても他の処理には影響しない。次に、ステップ１０ｃにてストレージ６内のワーク１ｂから各種設定を考慮して次に搬出させるワークを決定する。この時、ステップ１０ｂで並べた順にワークの仕様を確認し、次に搬出可能かを判断する。次に、搬出すべき選択ワークがあるか否かをステップ１０ｄで判断し、ある場合はステップ１０ｅで搬出ワークを決定し、処理を終了する。また、ステップＳ１０ｄで搬出すべき選択ワークが無い場合は、ステップ１０ｆにて空ワーク２を次搬出ワークとして決定し、処理を終了する。 Next, the flow of the unloading work determination process according to the first embodiment will be described with reference to FIG.
First, in step 10a, it is confirmed whether there is a setting instruction for forcibly unloading an empty workpiece. If there is a setting instruction for empty work unloading, the empty work is determined as the next unloading work in step 10f, and the process is terminated. Next, when there is no support for setting of empty work unloading in step S10a, the process proceeds to step 10b, and the works that can be unloaded in the storage 6 are rearranged in a preset priority order. By rearranging in priority order, even if the number of workpieces to be selected increases, other processes are not affected. Next, in step 10c, a work to be carried out next is determined in consideration of various settings from the work 1b in the storage 6. At this time, the workpiece specifications are confirmed in the order in which they are arranged in step 10b, and it is determined whether or not the workpiece can be subsequently unloaded. Next, it is determined in step 10d whether or not there is a selected work to be carried out. If there is, a carried-out work is determined in step 10e, and the process ends. If there is no selected work to be carried out in step S10d, the empty work 2 is determined as the next carry-out work in step 10f, and the process ends.

実施の形態２の搬出ワーク決定処理の流れについて、図３により説明する。
先ず、ステップ１０ｇで時刻指定の強制搬出の設定があるか否かを確認する。ステップＳ１０ｇで強制搬出の設定があり、且つ現在時刻がその設定された時刻に達していれば、ステップＳ１０ｅに進み、その設定されたワークを次に搬出させるワークとして選択し、処理を終了する。ステップＳ１０ｇで強制搬出の設定が無ければ、ステップ１０ａに進み、強制的に空ワークを搬出させる設定指示があるか否かを確認する。ステップＳ１０ａで空ワーク搬出の設定指示がある場合は、ステップ１０ｆにて空ワークを次搬出ワークとして決定し、処理を終了する。次に、ステップＳ１０ａで空ワーク搬出の設定支持がない場合は、ステップ１０ｂに進みストレージ６内で搬出可能なワークを予め設定された優先順に並び替える。優先順に並び替えることにより、選択対象ワーク数が多くなっても他の処理には影響しない。次に、ステップ１０ｃにてストレージ６内のワーク１ｂから各種設定を考慮して次に搬出させるワークを決定する。この時、ステップ１０ｂで並べた順にワークの仕様を確認し、次に搬出可能かを判断する。次に、搬出すべき選択ワークがあるか否かをステップ１０ｄで判断し、ある場合はステップ１０ｅで搬出ワークを決定し、処理を終了する。また、ステップＳ１０ｄで搬出すべき選択ワークが無い場合は、ステップ１０ｆにて空ワーク２を次搬出ワークとして決定し、処理を終了する。なお、ステップ１０ｃでワークを選択する時は、時刻指定強制搬出設定されたワークは選択対象外として、ワークを選択する。 Embodiment 2.
FIG. 3 is a flowchart for explaining the operation of the order correction system for the high-mix low-volume production line according to Embodiment 2 of the present invention.
The flow of the unloading work determination process according to the second embodiment will be described with reference to FIG.
First, in step 10g, it is confirmed whether or not there is a setting for forced carry-out with time designation. If forced unloading is set in step S10g and the current time has reached the set time, the process proceeds to step S10e, where the set work is selected as a work to be unloaded next, and the process ends. If there is no setting for forced unloading in step S10g, the process proceeds to step 10a to check whether there is a setting instruction for forcibly unloading the empty workpiece. If there is a setting instruction for empty work unloading in step S10a, the empty work is determined as the next unloading work in step 10f, and the process ends. Next, when there is no support for setting of empty work unloading in step S10a, the process proceeds to step 10b, and the works that can be unloaded in the storage 6 are rearranged in a preset priority order. By rearranging in priority order, even if the number of workpieces to be selected increases, other processes are not affected. Next, in step 10c, a work to be carried out next is determined in consideration of various settings from the work 1b in the storage 6. At this time, the workpiece specifications are confirmed in the order in which they are arranged in step 10b, and it is determined whether or not the workpiece can be subsequently unloaded. Next, it is determined in step 10d whether or not there is a selected work to be carried out. If there is, a carried-out work is determined in step 10e, and the process ends. If there is no selected work to be carried out in step S10d, the empty work 2 is determined as the next carry-out work in step 10f, and the process ends. When a work is selected in step 10c, the work that is set to be forcibly carried out at time designation is not selected and is selected.

実施の形態３の搬出ワーク決定処理の流れについて、図４により説明する。
実施の形態３においては、ワーク選択処理を行う時の制約条件を絶対制約と通常制約に分けたものである。絶対制約は次工程での設備的な制約事項などで、必ず守る必要のある制約とする。また、通常制約は諸条件により、制約を守ることが好ましいが、必ずしも絶対ではなく空ワークを出すよりかは、無理してでもワークを出すことができる制約とする。 Embodiment 3.
FIG. 4 is a flowchart for explaining the operation of the order correction system for a high-mix low-volume production line according to Embodiment 3 of the present invention.
The flow of the unloading work determination process according to the third embodiment will be described with reference to FIG.
In the third embodiment, the constraint conditions for performing the workpiece selection process are divided into absolute constraints and normal constraints. The absolute restriction is a restriction that must be observed because it is a facility restriction in the next process. In addition, it is preferable that the normal constraints be kept according to various conditions. However, it is not always absolute, and rather than an empty workpiece, it is assumed that the workpiece can be released even if it is impossible.

図４において、先ず、ステップ１０ａでは強制的に空ワークを搬出させる設定指示があるか否かを確認する。空ワーク搬出の設定指示がある場合は、ステップ１０ｆにて空ワークを次搬出ワークとして決定し、処理を終了する。次に、ステップＳ１０ａで空ワーク搬出の設定支持がない場合は、ステップ１０ｂに進みストレージ６内で搬出可能なワークを予め設定された優先順に並び替える。優先順に並び替えることにより、選択対象ワーク数が多くなっても他の処理には影響しない。次に、ステップ１０ｈでは通常制約による判断を行う。ステップ１０ｈの通常制約による判断を行って、搬出すべき選択ワークがあるか否かをステップ１０ｄで判断し、ある場合はステップ１０ｅで搬出ワークを決定し、処理を終了する。また、ステップＳ１０ｈ及びＳ１０ｄの通常制約では対象ワークが無かった場合は、ステップＳ１０ｉの絶対制約による判断を行う。ステップ１０ｈの絶対制約による判断を行って、搬出すべき選択ワークがあるか否かをステップ１０ｊで判断し、ある場合はステップ１０ｅで搬出ワークを決定し、処理を終了する。ここでも該当ワークが無かった場合は、ステップ１０ｆに進み、空ワーク２を次搬出ワークとして決定し、処理を終了する。   In FIG. 4, first, in step 10a, it is confirmed whether or not there is a setting instruction for forcibly carrying out an empty workpiece. If there is a setting instruction for empty work unloading, the empty work is determined as the next unloading work in step 10f, and the process is terminated. Next, when there is no support for setting of empty work unloading in step S10a, the process proceeds to step 10b, and the works that can be unloaded in the storage 6 are rearranged in a preset priority order. By rearranging in priority order, even if the number of workpieces to be selected increases, other processes are not affected. Next, in step 10h, a determination based on normal constraints is performed. In step 10h, a determination based on the normal restriction is made, and it is determined in step 10d whether or not there is a selected work to be carried out. Further, if there is no target workpiece in the normal constraints in steps S10h and S10d, a determination is made based on the absolute constraint in step S10i. In step 10h, a determination is made based on the absolute constraint, and it is determined in step 10j whether there is a selected work to be carried out. If there is no corresponding work, the process proceeds to step 10f, the empty work 2 is determined as the next carry-out work, and the process ends.
