本発明は、複数の設備を有する製造ラインにおける工程監視装置及び工程監視方法に関する。   The present invention relates to a process monitoring apparatus and a process monitoring method in a production line having a plurality of facilities.

複数の設備を順に通って、部品を加工あるいは検査を行う場合、従来は、設備間に仮置き台を設けて、次ぎの設備に投入される部品をひとつずつ置くようにしていた。この場合、例えば第１の設備の後段に設けた仮置き台に置かれた部品を第２の設備に投入すると、これを検知して、第１の設備による加工あるいは検査が再開するようになっていた。このようにすると、第１の設備で発生する不良品が第２の設備に流れないようにできるが、第１の設備と第２の設備とで動作時間が異なる場合には、待ち時間が発生して生産効率が悪くなるという問題があった。   In the case where parts are processed or inspected through a plurality of facilities in order, conventionally, a temporary table is provided between the facilities so that the parts to be put into the next facility are placed one by one. In this case, for example, when a part placed on a temporary table provided at the rear stage of the first facility is input to the second facility, this is detected, and processing or inspection by the first facility is resumed. It was. In this way, defective products generated in the first facility can be prevented from flowing to the second facility, but when the operating time differs between the first facility and the second facility, a waiting time occurs. As a result, there was a problem that production efficiency deteriorated.

この場合、第１の設備を連続的に運転できるように、仮置き台に多数個の部品が置かれることを許容するか、あるいは仮置き台を廃止するようにすると、生産効率は高くなる。しかし、未加工品又は不良品が紛れ込んでも気づかれず、これらの未加工品又は不良品が、次ぎの第２の設備に流れてしまうという問題があった。   In this case, if a large number of parts are allowed to be placed on the temporary table or the temporary table is eliminated so that the first facility can be operated continuously, the production efficiency is increased. However, there is a problem that even if a raw product or a defective product is mixed in, the raw product or a defective product is not noticed and flows to the next second facility.

なお、このような複数の設備にわたる加工又は検査に関する関連技術を開示する文献は見当たらなかった。   It should be noted that there was no document disclosing related technologies related to processing or inspection over such a plurality of facilities.

なお、上記括弧内の符号は、後述する実施形態に記載の具体的手段との対応関係を示す一例である。   In addition, the code | symbol in the said parenthesis is an example which shows a corresponding relationship with the specific means as described in embodiment mentioned later.

以下、図面を参照して、本発明の実施の形態を説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１は、本発明の一実施形態を実施するための製造ラインを示す。図１の製造ラインは、第１の設備１０と第２の設備２０とを備える、第２の設備２０は、第１の設備１０で加工された部品のうちの良品を、さらに加工するための設備である。本実施形態では、部品の加工を例にして説明するが、部品の検査においても同様である。   FIG. 1 shows a production line for carrying out one embodiment of the present invention. The production line of FIG. 1 includes a first facility 10 and a second facility 20. The second facility 20 is for further processing non-defective products among the parts processed by the first facility 10. Equipment. In the present embodiment, the processing of a component will be described as an example, but the same applies to the inspection of a component.

第１の設備は、部品を加工するための工具、部品を搬送するための搬送具等を備えているとともに、第１の計数計であるカウンタ１１を備えている。カウンタ１１は、第１の設備で加工された部品のうち良品の数をカウントするもので、良品数の総数に相当する累算値Ｎ１を後述する第２の設備の演算制御部２５へ送る。   The first equipment includes a tool for processing a part, a transport tool for transporting the part, and the like, and a counter 11 that is a first counter. The counter 11 counts the number of non-defective products among the parts processed by the first facility, and sends an accumulated value N1 corresponding to the total number of non-defective products to the operation control unit 25 of the second facility described later.

第２の設備は、第１の設備と同様に、第２の設備で部品を加工するための工具、部品を搬送するための搬送具等を備えているとともに、第２の計数計であるカウンタ２１、第３の計数計であるカウンタ２３、演算制御部２５を備えている。カウンタ２１は、第２の設備で加工された部品のうち良品の数をカウントするもので、第２の設備の良品の総数を示す累算値Ｎ２を演算制御部２５へ送る。カウンタ２３は、第２の設備で加工された部品のうち不良品の数をカウントするもので、第２の設備の不良品の総数を示す累算値Ｎ３を演算制御部２５へ送る。   The second equipment, like the first equipment, is equipped with a tool for processing parts in the second equipment, a transport tool for transporting the parts, and the like, and a counter that is a second counter 21, a counter 23 that is a third counter, and an arithmetic control unit 25. The counter 21 counts the number of non-defective products among the parts processed by the second facility, and sends an accumulated value N2 indicating the total number of non-defective products of the second facility to the arithmetic control unit 25. The counter 23 counts the number of defective products among the parts processed by the second equipment, and sends an accumulated value N3 indicating the total number of defective products of the second equipment to the arithmetic control unit 25.

演算制御部２５では、カウンタ２１、２２から送られる第２の設備の良品総数Ｎ２と不良品総数Ｎ３とを合計して、Ｎ２＋Ｎ３を計算する。これは、第２の設備２０で加工された部品総数である。次に、第２の設備で加工された部品総数Ｎ２＋Ｎ３と、第１の設備１０の良品数Ｎ１を比較する。第１の設備１０の良品数Ｎ１は、第２の設備に加工のために搬入する部品の数であるから、
Ｎ１＞Ｎ２＋Ｎ３ （１）
の関係を満たしていれば、第２の設備での加工工程は、問題がないと判断できる。すなわち、ある設備に搬入された部品数Ｎ１は、加工が済んで搬出される部品数Ｎ２＋Ｎ３と加工中の部品数を足したものに等しいものであるから、通常は関係（１）を満たしているものである。 In the arithmetic control unit 25, the non-defective product total number N2 and the defective product total number N3 sent from the counters 21 and 22 are summed to calculate N2 + N3. This is the total number of parts processed by the second facility 20. Next, the total number N2 + N3 processed by the second facility is compared with the number N1 of non-defective products of the first facility 10. Since the number of non-defective items N1 of the first equipment 10 is the number of parts to be carried into the second equipment for processing,
N1> N2 + N3 (1)
If the relationship is satisfied, it can be determined that there is no problem in the processing step in the second facility. That is, the number of parts N1 carried into a certain facility is equal to the number of parts N2 + N3 to be carried out after processing and the number of parts being processed, and therefore normally satisfies the relationship (1). Is.

本実施形態では、各カウンタからカウント結果が送られてくるたびに、演算制御部２１では、関係（１）を満たしているかをチェックするようにする。少なくとも、第２の設備に設けられたカウンタ２１と２２からカウント数が送られてくる場合は、必ず関係（１）が満たされているか否かがチェックされる。このチェックの結果、関係（１）が満たされず、Ｎ１＝Ｎ２＋Ｎ３となった場合には、何らかの異常があると判断して、設備の運転をストップする。これは、第２の設備で加工中の部品が存在しないことを意味しており、必ずしも異常とはいえないが、通常の状況ではないので、設備の運転を中止して点検する必要があるということができる。なお、Ｎ１＜Ｎ２＋Ｎ３となると、第２の設備で加工されるべき部品以外の部品、例えば第１の設備での加工が済んでいない部品、不良品等が、第２の設備で加工されたことになる。   In this embodiment, every time a count result is sent from each counter, the arithmetic control unit 21 checks whether the relationship (1) is satisfied. At least when the count number is sent from the counters 21 and 22 provided in the second facility, it is always checked whether or not the relationship (1) is satisfied. As a result of this check, if the relationship (1) is not satisfied and N1 = N2 + N3, it is determined that there is some abnormality, and the operation of the equipment is stopped. This means that there is no part being processed in the second equipment, which is not necessarily abnormal, but it is not a normal situation, so it is necessary to stop the operation of the equipment and inspect it. be able to. When N1 <N2 + N3, parts other than parts to be processed by the second facility, for example, parts that have not been processed by the first facility, defective products, etc. have been processed by the second facility. become.

以上のように、本実施形態によると、生産効率を向上できるとともに、工程に異常があることを早期に発見することができる。   As described above, according to the present embodiment, it is possible to improve production efficiency and to discover that there is an abnormality in the process at an early stage.

次に、図２及び図３に示す動作フローを参照して、本実施形態の動作を説明する。なお、部品の加工を例にして説明するが、部品検査においても同様のフローとなる。   Next, the operation of the present embodiment will be described with reference to the operation flow shown in FIGS. Note that the processing of parts will be described as an example, but the same flow is performed in parts inspection.

図２は、第１の設備における動作を説明するためのフロー図である。まず、第１の設備で１つの部品に対して加工が完了する（ステップＳ３１）と、良品か不良品かが判定され（ステップＳ３２）、不良品であればラインから取り除かれる（ステップＳ３３）。良品であれば、次工程である第２の設備に送られて加工すべきものであり、本実施形態では、カウンタ１１によりその数をカウントする。すなわちカウンタ１１の出力に１を加える（ステップＳ３４）。次いで、良品を第２の設備に送るとともに、カウンタ１１の累算値（Ｎ１）を第２の設備２０の演算制御部２５に送る（ステップＳ３５）。   FIG. 2 is a flowchart for explaining the operation in the first facility. First, when processing for one part is completed in the first equipment (step S31), it is determined whether the product is a non-defective product or a defective product (step S32), and if it is a defective product, it is removed from the line (step S33). If it is a non-defective product, it is sent to the second equipment as the next process and should be processed. In the present embodiment, the number is counted by the counter 11. That is, 1 is added to the output of the counter 11 (step S34). Next, the non-defective product is sent to the second equipment, and the accumulated value (N1) of the counter 11 is sent to the arithmetic control unit 25 of the second equipment 20 (step S35).

図３は、第２の設備２０における動作を説明するためのフロー図である。まず、第１の設備から第２の設備２０での加工のために、部品が搬送される（ステップＳ４１）。搬送される部品は、第１の設備１０でチェック済みの良品である。その後、第２の設備２０で所定の加工が行われる（ステップＳ４２）。加工が完了した部品は、良品であるか否かが判定される（ステップＳ４３）。良品と判定された部品に対しては、第２の設備２０の良品用カウンタ２１でカウントされて、Ｎ２に１が加わり、演算制御部２５に送られる（ステップＳ４３）。その結果、演算制御部２５では、そのときまでの各カウンタの累算値を用いて、Ｎ１＞Ｎ２＋Ｎ３を満足しているか否かが判定される（ステップＳ４６）。この関係が満たされていれば、正常であるので、第２の設備２０の運転は継続される。しかし、この関係が満たされない、すなわちＮ１＝Ｎ２＋Ｎ３となった場合には、何らかの異常があったと判定され、第２の設備２０の運転は中止される（ステップＳ４７）。その後異常の原因が究明されることになる。   FIG. 3 is a flowchart for explaining the operation in the second facility 20. First, parts are conveyed from the first equipment for processing in the second equipment 20 (step S41). The parts to be conveyed are non-defective products that have been checked by the first equipment 10. Thereafter, predetermined processing is performed in the second equipment 20 (step S42). It is determined whether the processed part is a non-defective product (step S43). The parts determined to be non-defective are counted by the non-defective counter 21 of the second equipment 20, 1 is added to N2, and the result is sent to the arithmetic control unit 25 (step S43). As a result, the arithmetic control unit 25 determines whether or not N1> N2 + N3 is satisfied using the accumulated values of the counters up to that time (step S46). If this relationship is satisfied, it is normal and the operation of the second facility 20 is continued. However, when this relationship is not satisfied, that is, when N1 = N2 + N3, it is determined that there is some abnormality, and the operation of the second facility 20 is stopped (step S47). Then the cause of the abnormality will be investigated.

また、ステップＳ４３で、第２の設備２０で加工された部品が不良品であった場合は、不良品用のカウンタ２３の値が１だけカウントアップされ、カウンタの累算値Ｎ３が演算制御部２５に送られる（ステップＳ４３）。その結果、演算制御部２５では、そのときまでの累算値を用いて、Ｎ１＞Ｎ２＋Ｎ３を満足しているか否かが判定される（ステップＳ４６）。この関係が満たされていれば、第２の設備２０の運転は継続されるが、この関係が満たされない場合、すなわちＮ１＝Ｎ２＋Ｎ３の場合には、第２の設備２０の運転は中止される（ステップＳ４７）。その後異常の原因が究明されることになる。   If the part processed by the second equipment 20 is a defective product in step S43, the value of the counter 23 for the defective product is incremented by 1, and the accumulated value N3 of the counter is calculated by the arithmetic control unit. 25 (step S43). As a result, the arithmetic control unit 25 determines whether or not N1> N2 + N3 is satisfied using the accumulated value up to that time (step S46). If this relationship is satisfied, the operation of the second facility 20 is continued, but if this relationship is not satisfied, that is, if N1 = N2 + N3, the operation of the second facility 20 is stopped ( Step S47). Then the cause of the abnormality will be investigated.

上記の実施形態では、第１と第２の設備を有する製造ラインを例にして説明したが、本発明は、３以上の設備を持つ製造ラインにおいても適用可能である。図４に、第３の設備３０を備える製造ラインの一例を示す。第３の設備３０においても、第３の設備で加工された部品のうちの良品をカウントするカウンタ３１と、不良品をカウントするカウンタ３３を備えており、さらに演算制御部３５を備えている。演算制御部３５では、カウンタ３１でカウントされる第３の設備による良品の累算値Ｎ４と、カウンタ３３でカウントされる第３の設備による不良品の累算値Ｎ５とが入力され、その和（Ｎ４＋Ｎ５）が計算される。そして、その和（Ｎ４＋Ｎ５）と、第２の設備の良品数すなわちカウンタ２１の累算値Ｎ２とが比較される。その結果、Ｎ２＞Ｎ４＋Ｎ５の関係が満たされていると、第３の設備での加工が継続され、Ｎ２＝Ｎ４＋Ｎ５となると、何らかの異常が発生しているとして、第３の設備における加工が停止される。   In the above embodiment, the production line having the first and second facilities has been described as an example, but the present invention can also be applied to a production line having three or more facilities. In FIG. 4, an example of a production line provided with the 3rd installation 30 is shown. The third equipment 30 also includes a counter 31 that counts non-defective products among the parts processed by the third equipment, a counter 33 that counts defective products, and further includes an arithmetic control unit 35. In the calculation control unit 35, the cumulative value N4 of the non-defective product by the third equipment counted by the counter 31 and the cumulative value N5 of the defective product by the third equipment counted by the counter 33 are inputted, and the sum (N4 + N5) is calculated. Then, the sum (N4 + N5) is compared with the number of non-defective products of the second equipment, that is, the accumulated value N2 of the counter 21. As a result, when the relationship of N2> N4 + N5 is satisfied, the processing at the third facility is continued, and when N2 = N4 + N5, it is assumed that some abnormality has occurred, and the processing at the third facility is stopped. The

このように、３以上の設備を備える製造ラインに対しては、図１に示すような、第２の設備における良品カウンタと不良品カウンタと演算制御部を、第３以降の設備に備えるようにして、てすべての工程を監視するのがよい。しかし場合によっては、続けて加工するペアの設備を選択して、選択したペアの設備に対して工程監視を行うようにしてもよい。   Thus, for a production line having three or more facilities, the third and subsequent facilities are provided with a non-defective product counter, a defective product counter, and an arithmetic control unit in the second facility as shown in FIG. It is better to monitor all processes. However, in some cases, a pair of equipment to be subsequently processed may be selected, and process monitoring may be performed on the selected pair of equipment.

以上説明したように、本実施形態は、複数の設備にわたって部品が移送される工程について、その効率を向上させるともに、未加工品や未検査品が流れてしまう事故を防ぐことができる。特に、目視しにくい部品の加工工程やあるいは部品の内部の検査工程などがあり、従来では未加工品・未検査品の混入が把握しにくい場合であっても、本実施形態によると、未加工品・未検査品の混入を確実に防止することができる。   As described above, the present embodiment can improve the efficiency of the process of transferring parts over a plurality of facilities and can prevent an accident in which unprocessed products and uninspected products flow. In particular, according to the present embodiment, even if it is difficult to grasp the mixing of unprocessed products and uninspected products in the past, there are processing processes for parts that are difficult to see or inspection processes inside the parts, etc. It is possible to reliably prevent mixing of products and uninspected products.

なお、加工と検査が混在する工程に対しても、本発明は適用できる。また、加工や検査の工程は、製造、組み立て、処理、試験等の工程を含み、最も広い概念で解釈されるべきものである。   Note that the present invention can also be applied to a process in which processing and inspection are mixed. The processing and inspection processes include processes such as manufacturing, assembly, processing, and testing, and should be interpreted in the broadest concept.
