レーザ加工機やパンチプレスの板材加工機により、素材板材から複数の部品板材を切り抜く加工を行う場合がある。このような加工を行う制御プログラムを作成するに際して、素材板材に対する各部品板材の配置を定める処理であるネスティングが行われる。このネスティングは、複数の部品板材の生産単位となるネスティングオーダ毎に行われる。
従来、このネスティングオーダを作成するにつき、何を、いつまでに加工しなければならないかを優先してネスティングオーダを作成し、切り抜き加工を実施していた。

切り抜き加工が行われた部品板材は、ボール盤によるドリル加工や、曲げ加工機による曲げ加工、溶接等の後工程が行われる。部品板材によって、どのような後工程が行われるかは、種々異なる。
しかし、上記のように従来は、単に、何を、いつまでに加工しなければならないかを優先してネスティングオーダを作成しており、後工程を考慮していない。そのため、一部の後工程装置の負荷が大きくなって、一部の後工程の処理待ち状態となる仕掛かり品の部品板材が増え、また他の後工程に空きが発生することがある。そのため、切り抜き加工を行う板材加工機や各種の後工程装置を含む板材加工設備の全体の稼働効率が悪くなり、設備全体として加工に要する時間が長くなるという課題がある。 The component plate material that has been cut out is subjected to post-processes such as drilling with a drilling machine, bending with a bending machine, and welding. Depending on the component plate material, what kind of post-process is performed varies.
However, as described above, conventionally, a nesting order is created simply by giving priority to what and when it has to be processed, and no subsequent process is considered. For this reason, the load on some post-process devices is increased, and the number of in-process component plate materials that are waiting for processing in some post-processes increases, and other post-processes may be vacant. Therefore, there is a problem that the overall operation efficiency of the plate material processing equipment including the plate material processing machine for performing the cut-out processing and various post-processing devices is deteriorated, and the time required for the processing as the whole equipment is increased.

つぎに、ネスティングオーダ生成装置２０につき説明する。加工予定部品板材記憶手段１４は、板材加工設備１で加工する予定の各部品板材ｍについての部品板材データＤ、およびその部品板材ｍ毎の数量を記憶した手段である。部品板材データＤについては後述する。   Next, the nesting order generation device 20 will be described. The processing scheduled component plate material storage means 14 is a means for storing the component plate material data D for each component plate material m scheduled to be processed by the plate material processing facility 1 and the quantity for each component plate material m. The component plate material data D will be described later.

ネスティングオーダ生成手段２０は、加工予定部品板材記憶手段１４で記憶された加工予定の部品板材ｍを、例えば図３のように、各生産順位のネスティングオーダＮＯに分ける手段である。このネスティングオーダ生成手段２０で、適切なネスティングオーダＮＯに分けるための手段として、次の板材加工時間見積り装置１０が設けられる。   The nesting order generation unit 20 is a unit that divides the scheduled component plate material m stored in the scheduled processing component plate material storage unit 14 into nesting order numbers of respective production orders as shown in FIG. 3, for example. As a means for dividing the nesting order generation means 20 into appropriate nesting order NOs, the following plate material processing time estimation device 10 is provided.

この板材加工時間見積り装置１０は、工程データ判別手段１１と、単位加工時間記憶手段１２と、部品毎工程時間見積もり手段１３とを備える。   The plate material processing time estimation device 10 includes process data determination means 11, unit processing time storage means 12, and part-by-part process time estimation means 13.

工程データ判別手段１１は、部品図形データＤに含まれた後工程を示すデータを読み取って後工程の種類、およびその後工程における単位加工の数量を判別し、かつ前記部品図形データＤにおける板材加工機２で行う加工の数量を認識する手段である。
部品図形データＤは、部品板材ｍの形状を示す図形Ｇｍのデータであって、いわゆるＣＡＤ（コンピュータ支援設計）データであり、図形Ｇｍを構成する各線分のデータと、属性データ等で構成される。部品図形データＤには、板材加工機２で加工する部品板材ｍの外形線Ｌや、部品内部の穴加工等の内部加工部Ｉの線の他に、各後工程で加工するデータを含むものとされる。後工程で加工するデータとしては、例えば、ドリル，タップ，リーマ，皿もみ等の加工の種類と位置を示す各種のシンボルマークＨや、曲げ加工を行う曲げ線，溶接を行う溶接ラインの線状マークＬＢ等がある。シンボルマークＨや線状マークＬＢ等が、どの種類の後工程を示すかは、シンボルマークの形状、線の色、線種、レイヤ等で区別可能とされていても良い。
工程データ判別手段１１は、部品図形データＤに含まれるシンボルマークＨの個数からそのシンボルマークＨで示される後工程の回数である数量を判別し、また線状マークＬＢの本数や長さを認識する。
工程データ判別手段１１よって認識する板材加工機２で行う加工の数量は、部品板材ｍの外形線の長さである。内部加工部Ｉを含む場合は、その内部加工部Ｉとなる穴の個数や、内部加工部Ｉの長さについても、加工数量として認識する。 The process data discriminating means 11 reads the data indicating the post-process included in the part graphic data D to discriminate the type of the post-process and the quantity of unit machining in the post-process, and the plate material processing machine in the part graphic data D 2 is a means for recognizing the quantity of processing performed in 2.
The part graphic data D is data of a graphic Gm indicating the shape of the component board m, and is so-called CAD (computer-aided design) data, and is composed of data of each line segment constituting the graphic Gm, attribute data, and the like. . The component graphic data D includes data processed in each subsequent process in addition to the outline L of the component plate m processed by the plate processing machine 2 and the line of the internal processing portion I such as drilling of holes inside the component. It is said. As data to be processed in the subsequent process, for example, various symbol marks H indicating the type and position of processing such as drills, taps, reamers, countersunks, etc., bending lines for bending, and linear shapes of welding lines for welding There are marks LB and the like. Which type of post-processes the symbol mark H, the line mark LB, etc. indicate may be made distinguishable by the symbol mark shape, line color, line type, layer, and the like.
The process data discriminating means 11 discriminates the quantity that is the number of subsequent processes indicated by the symbol mark H from the number of symbol marks H included in the part graphic data D, and recognizes the number and length of the linear marks LB. To do.
The quantity of processing performed by the plate material processing machine 2 recognized by the process data discrimination means 11 is the length of the outline of the component plate material m. When the internal processing portion I is included, the number of holes to be the internal processing portion I and the length of the internal processing portion I are also recognized as the processing quantity.

単位加工時間記憶手段１２は、各後工程装置３（３A 〜３C ）における単位加工に要する時間、および板材加工機２の単位加工に要する時間を記憶した手段である。単位加工時間は、１回の加工に要する時間、または単位長さの加工に要する時間とされる。単位長さは任意に設定すれば良い。
例えば、ボール盤からなる後工程装置３A において、ドリル，タップ，リーマ，皿もみ等の各加工が行われるとすると、ドリル加工等の各加工につき、１回の加工に要する時間が単位加工時間として記憶される。曲げ加工では、１回の曲げに要する時間が単位加工時間とされる。溶接の場合は、溶接線の単位長さの作業に要する時間が単位加工時間とされる。
単位加工時間記憶手段１２には、同じ後工程装置３での複数回の加工につき、各回の加工の間に待ち時間が必要な場合は、その待ち時間が記憶される。また、単位加工時間記憶手段１２には、後工程装置３への部品板材ｍの搬入，搬出に要する時間も記憶させておくことが好ましい。 The unit processing time storage means 12 is a means for storing the time required for unit processing in each post-processing device 3 (3 A to 3 C ) and the time required for unit processing of the plate material processing machine 2. The unit processing time is a time required for one processing or a time required for processing of a unit length. The unit length may be set arbitrarily.
For example, if each process such as drilling, tapping, reamer, dishing, etc. is performed in the post-process apparatus 3 A composed of a drilling machine, the time required for one process for each process such as drilling is set as a unit processing time. Remembered. In the bending process, a time required for one bending is set as a unit processing time. In the case of welding, the time required for the work of the unit length of the weld line is the unit processing time.
The unit machining time storage means 12 stores a waiting time for a plurality of times of machining in the same post-process device 3 when a waiting time is required between each machining. Further, it is preferable that the unit machining time storage means 12 also stores the time required to carry in and carry out the component plate material m to and from the post-processing device 3.

部品毎工程時間見積もり手段１３は、工程データ判別手段１１で判別した各部品板材ｍの後工程の種類および後工程の単位加工の数量、並びに板材加工機２で行う加工の数量から、単位加工時間記憶手段１２の記憶データを用いて、各部品板材ｍの後工程に要する加工時間、板材加工機２の加工に要する加工時間、およびこれら加工時間の和を見積もる手段である。例えば、ボール盤からなる後工程装置３A で行うドリル加工箇所がｎ箇所あり、１回の加工時間がＴ秒であるとすると、（加工時間Ｔ）×（穴数ｎ）が、後工程時間とされる。この後工程時間は、実加工に要する時間だけでも良いが、部品板材ｍの搬入搬出時間や、各回の加工の間に要する時間が実加工時間に対して大きく影響するときは、これら搬入搬出時間や、各回の加工の間に要する時間も加算する。これらの搬入搬出時間や各回の加工の間に要する時間につき、どのような場合に加算するかは、演算規則を任意に設定しておいて、その演算規則に従って計算するようにすれば良い。 The part-by-part process time estimation means 13 determines the unit processing time from the type of post-process of each component plate material m determined by the process data determination means 11 and the quantity of unit processing in the post-process, and the quantity of processing performed in the plate material processing machine 2. It is a means for estimating the processing time required for the post-process of each component plate material m, the processing time required for processing by the plate material processing machine 2, and the sum of these processing times using the stored data of the storage means 12. For example, assuming that there are n drilling points to be performed by the post-processing apparatus 3 A made of a drilling machine and one processing time is T seconds, (processing time T) × (number of holes n) Is done. This post-process time may be only the time required for actual machining. However, when the time required for carrying in / out the component plate material m and the time required for each machining greatly affect the actual machining time, these carry-in / out times Also add the time required between each machining. What kind of case should be added to these loading / unloading times and the time required for each processing may be calculated according to the calculation rules set arbitrarily.

ネスティングオーダ生成装置２０は、コンピュータおよびこれに実行されるプログラム等より、次の各手段が構成されたものである。このネスティングオーダ生成装置２０は、前記板材加工時間見積り装置１０と、前記工程別・加工状況監視手段９と、後工程別・待ち時間把握手段１９と、前記加工予定部品板材記憶手段１４と、前記ネスティングオーダ生成手段２１とを備える。   The nesting order generation apparatus 20 is configured by the following means including a computer and a program executed on the computer. The nesting order generation device 20 includes the plate material processing time estimation device 10, the process / processing status monitoring unit 9, the post-process / waiting time grasping unit 19, the processing target component plate material storage unit 14, Nesting order generation means 21.

後工程別・待ち時間把握手段１９は、前記部品毎工程時間見積もり手段１３で得られる後工程に要する加工時間と、工程別・加工状況監視手段９の監視結果である後工程状況から、各後工程の加工待ち待ち時間を計算する手段である。すなわち、工程別・加工状況監視手段９の監視結果である後工程状況として、ある後工程装置３に、ある部品種類の部品板材ｍが、Ａ個加工待ちであるとすると、その加工待ちの部品種類の部品板材ｍにつき、その後加工に要する時間を計算させ、待ち個数Ａを掛けることで、加工待ち待ち時間が算出できる。なお、部品板材ｍの後加工に要する時間は、その待ち状態にある部品板材ｍの生産についてのネスティングオーダの決定時に、後工程別・待ち時間把握手段１９によって計算されているので、その計算された時間を記憶装置の所定の記憶領域に記憶させておくことで、改めて計算し直しことなく、その記憶された後加工所要時間を用いるようにする。   The post-process / waiting time grasping means 19 determines each post-process from the machining time required for the post-process obtained by the part-by-part process time estimating means 13 and the post-process status that is the monitoring result of the process-specific / machining status monitoring means 9. It is a means for calculating the processing waiting time for the process. That is, as a post-process status that is a monitoring result of the process / process status monitoring means 9, if a part plate material m of a certain component type is waiting to be processed A in a certain post-process device 3, the part that is waiting to be processed The processing waiting time can be calculated by calculating the time required for subsequent processing for each type of component plate material m and multiplying by the waiting number A. It should be noted that the time required for the post-processing of the component board m is calculated by the post-process / waiting time grasping means 19 when the nesting order for the production of the component board m in the waiting state is determined. The stored time is stored in a predetermined storage area of the storage device, and the stored post-processing time is used without recalculation.

ネスティングオーダ生成手段２１は、前述のように、加工予定部品板材記憶手段１４で記憶された加工予定の部品板材ｍを、各生産順位のネスティングオーダＮＯに分ける手段であるが、この分ける処理につき、部品毎工程時間見積もり手段１３で得られる部品板材毎の加工時間の和を用い、各後工程装置３（３A 〜３C ）の加工待ち待ち時間が均等化されるように、各生産順位のネスティングオーダＮＯに分ける。この加工待ち待ち時間の均等化については、計算規則を適宜定めておいて、その計算規則に従って計算した結果、加工待ち待ち時間が均等化されるようにすれば良い。 As described above, the nesting order generation unit 21 is a unit that divides the scheduled component plate material m stored in the scheduled processing component plate material storage unit 14 into the nesting order NO of each production order. Using the sum of the machining times for each part plate material obtained by the part-by-part process time estimation means 13, the production waiting times of the respective post-process devices 3 (3 A to 3 C ) are equalized. Divide into nesting order NO. As for the equalization of the waiting time for machining, a calculation rule may be appropriately determined, and as a result of calculation according to the calculation rule, the waiting time for machining may be equalized.

ネスティングオーダ生成手段２１は、工程時間演算部２１ａと、比較部２１ｂと、決定部２１ｃとを有していて、工程時間演算部２１ａは、加工待ち待ち時間が均等化されるネスティングオーダＮＯの分け方の候補を複数作成する。比較部２１ｂは、これら複数のネスティングオーダＮＯの分け方の候補を、例えば表示装置の画面に出力させて比較可能とする。決定部２１ｃは、比較部２１ｂで比較可能とされた複数のネスティングオーダＮＯの分け方の候補から、オペレータの入力に従って、任意の一つを決定させる。   The nesting order generation means 21 includes a process time calculation unit 21a, a comparison unit 21b, and a determination unit 21c. The process time calculation unit 21a divides the nesting order NO in which the waiting time for processing is equalized. Create multiple candidates. The comparison unit 21b outputs the candidates for dividing the plurality of nesting order NOs, for example, on the screen of the display device so that the comparison is possible. The determination unit 21c determines an arbitrary one from the candidates for dividing the plurality of nesting order NOs that can be compared by the comparison unit 21b in accordance with the input of the operator.

この構成の板材加工時間見積り装置１０によると、工程データ判別手段１１により、部品図形データＤに含まれた後工程を示すシンボルマークＨや線状マークＬＢ，あるいは色，レイヤ等から識別されるデータを読み取って、後工程の種類、およびその後工程における単位加工の数量を判別する。また、部品図形データＤにおける板材加工機２で行う加工の数量を認識する。
部品毎工程時間見積もり手段１３は、工程データ判別手段１１で判別した各部品板材ｍの後工程の種類および後工程の単位加工の数量、並びに板材加工機２で行う加工の数量から、単位加工時間記憶手段１２の記憶データを用いて、各部品板材ｍの後工程に要する加工時間および板材加工機２による加工時間の和を算出する。
このように、部品図形データＤに含まれた後工程を示すデータを読み取って後工程の種類およびその後工程における単位加工の数量を認識するため、板材部品ｍ毎の加工時間を容易に見積もることができる。このように板材部品毎の加工時間の見積もり行えると、各後工程３の負荷が均等化される生産計画が用に容易に行える。 According to the plate material processing time estimation device 10 having this configuration, the process data discriminating means 11 identifies data identified from the symbol mark H or linear mark LB or the color, layer, etc., indicating the subsequent process included in the part graphic data D. To determine the type of the post-process and the quantity of unit processing in the post-process. Also, the quantity of processing performed by the plate material processing machine 2 in the part graphic data D is recognized.
The part-by-part process time estimation means 13 determines the unit processing time from the type of post-process of each component plate material m determined by the process data determination means 11 and the quantity of unit processing in the post-process, and the quantity of processing performed in the plate material processing machine 2. The sum of the processing time required for the subsequent process of each component plate material m and the processing time by the plate material processing machine 2 is calculated using the stored data in the storage means 12.
As described above, since the data indicating the post-process included in the part graphic data D is read to recognize the type of the post-process and the quantity of unit processing in the post-process, it is possible to easily estimate the processing time for each plate material part m. it can. Thus, if the processing time for each plate material part can be estimated, a production plan in which the load of each post-process 3 is equalized can be easily performed.

また、この構成のネスティングオーダ生成装置２０によると、後工程別・待ち時間把握手段１９は、部品毎工程時間見積もり手段１０で得られる後工程に要する加工時間と、加工状況監視手段９の監視結果である後工程状況から、各後工程の加工待ち待ち時間を計算する。ネスティングオーダ生成手段２０は、部品毎工程時間見積もり手段で得られる部品板材ｍ毎の加工時間の和を用い、各後工程の加工待ち待ち時間が均等化されるように、加工予定部品板材記憶手段１４で記憶された加工予定の部品板材ｍを、各生産順位のネスティングオーダＮＯに分ける。
このため、この生成されたネスティングオーダＮＯに従ってネスティングを行い、板材加工機２による加工を行うと、後工程装置の負荷が均等化し、各後工程の加工待ち待ち時間が均等化、すなわち平準化される。 Further, according to the nesting order generation device 20 having this configuration, the post-process / waiting time grasping means 19 is the processing time required for the post-process obtained by the part-by-part process time estimating means 10 and the monitoring result of the machining status monitoring means 9. From the post-process status, the waiting time for processing of each post-process is calculated. The nesting order generation means 20 uses the sum of the machining times for each part board m obtained by the part-by-part process time estimation means, so that the waiting time for waiting for machining in each subsequent process is equalized. The component plate material m scheduled to be processed stored in 14 is divided into nesting order numbers of respective production orders.
For this reason, when nesting is performed in accordance with the generated nesting order NO and processing is performed by the plate material processing machine 2, the load of the post-process apparatus is equalized, and the waiting time for processing in each post-process is equalized, that is, leveled. The

なお、上記のように単位加工時間記憶手段１２に記憶させる各工程の時間や、後工程・待ち時間把握手段１９で計算される時間については、日々の生産で実際の加工時間と予測時間とを比較して、差分を反映させて、単位加工時間記憶手段１２に記憶させる時間や、後工程・待ち時間把握手段１９の計算方法を修正して行くことにより、時間見積もりの制度を上げることができる。   In addition, about the time of each process memorize | stored in the unit machining time memory | storage means 12 as mentioned above, and the time calculated by the post process and waiting time grasping means 19, actual machining time and estimated time are calculated by daily production. In comparison, the time estimation system can be improved by reflecting the difference and correcting the time stored in the unit machining time storage means 12 and the calculation method of the post-process / waiting time grasping means 19. .

このように、ネスティングする部品板材ｍを集めた時点が、これから生産する切り取り加工時間の予測と、曲げ工程等の後工程の加工時間の予測をすることができ、各後工程の負荷に応じて、生産する部品板材ｍの絞り込みを実施することができる。これにより、板材加工設備１を効率的に稼働させることができる。   In this way, when the component plate materials m to be nested are collected, it is possible to predict the cutting time to be produced from now on and to predict the processing time of the post-process such as the bending process, depending on the load of each post-process. The component plate material m to be produced can be narrowed down. Thereby, the board | plate material processing equipment 1 can be operated efficiently.
