Description
本発明は、線材の加工方法に関し、例えば、絶縁電線を製造するために、線材である導体への樹脂の被覆等の加工を施す線材の加工方法に関する。 The present invention relates to a method of processing a wire, and, for example, to a method of processing a wire that performs processing such as coating a resin on a conductor that is a wire to produce an insulated wire.
線材を樹脂によって被覆した電線を製造する技術として、押出ラインが加減速される際に、押出ラインがもつ固有な制御特性に則った外径制御を可能とし、徐々に線速を上げ、あらかじめ設定しておいた定常製造線速とする立ち上げ時における立ち上げ時間を短縮するものが知られている（例えば、特許文献１参照）。 As a technology for manufacturing wires coated with resin, the outer diameter can be controlled according to the inherent control characteristics of the extrusion line when the extrusion line is accelerated and decelerated, and the wire speed is gradually increased and set in advance. There is known one that shortens the start-up time at the time of start-up as a steady production linear speed (for example, see Patent Document 1).
また、定量的に押出し機から押し出される被覆材を所定時間排出せしめ、該排出された被覆材の重量を計量することにより、該重量と所定時間とから単位時間の押出し量が演算され、該演算値と予め被覆材の材質・線種・線径等に基づいて予め求めておいた線材表面に被覆する被覆材の被覆量とに基づいて押出し機内を走行させる線材の線速が演算されるようにすることも知られている（例えば、特許文献２参照）。 Further, by discharging the covering material quantitatively extruded from the extruder for a predetermined time and measuring the weight of the discharged covering material, the extrusion amount per unit time is calculated from the weight and the predetermined time. The wire speed of the wire running in the extruder is calculated based on the value and the coating amount of the coating material to be coated on the surface of the wire previously obtained based on the material, wire type, wire diameter, etc. of the coating material It is also known to (see, for example, Patent Document 2).
線材に加工を施す設備を複数備えた施設では、次の線材への切り替え、押出型の変更あるいは樹脂の変更のときの停止状態が複数の設備で同時期となること（干渉停止と呼ばれる）がある。そのため、一人の作業者が複数の設備の操作を行う状況では、停止状態の何れか一つの設備に対して作業者が作業を行っている間、他の停止状態の設備は、停止状態のまま放置されることがある。このような停止状態で放置される設備があると、施設全体の稼働効率が低下してしまう。 In a facility equipped with multiple facilities for processing a wire, switching to the next wire, changing the extrusion mold, or changing the resin may occur simultaneously with multiple facilities (called interference stop). is there. Therefore, in a situation where one worker operates multiple facilities, while the worker is working on any one of the stopped facilities, the other stopped facilities remain in the stopped state. May be left unattended. If there is equipment that is left in such a stopped state, the operating efficiency of the entire facility is reduced.
本発明の目的は、高い稼働効率で線材に加工を施すことが可能な線材の加工方法を提供することにある。 The objective of this invention is providing the processing method of a wire which can process a wire with high operation efficiency.
上記課題を解決することのできる本発明の線材の加工方法は、繰り出される線材に加工を施して巻き取る複数の加工設備で複数の前記線材を同時に加工する線材の加工方法であって、
前記複数の加工設備についてそれぞれ、前記線材に加工が施された加工線の巻取長を計測し、製造する前記加工線の要求長、前記加工線の巻取長及び前記線材の線速に基づいて、前記線材に対する加工終了予定時刻を算出し、前記加工終了予定時刻及び前記加工設備における加工終了から次の加工開始までに要する準備時間に基づいて次の加工を開始する加工開始予定時刻を算出し、
一つの加工設備における前記加工終了予定時刻と前記加工開始予定時刻との間で、他の加工設備が加工終了予定時刻となる場合に、その旨を警報することを特徴とする。
The wire rod processing method of the present invention that can solve the above-mentioned problem is a wire rod processing method that simultaneously processes a plurality of the wire rods with a plurality of processing facilities that process and wind up the fed wire rod,
For each of the plurality of processing facilities, the winding length of the processed wire that is processed on the wire is measured, and based on the required length of the processed wire to be manufactured, the winding length of the processed wire, and the wire speed of the wire Then, the processing end scheduled time for the wire is calculated, and the processing start scheduled time for starting the next processing is calculated based on the processing end scheduled time and the preparation time required from the processing end to the next processing start in the processing equipment. And
A warning is given to another processing facility when the processing end scheduled time is between the processing end scheduled time and the processing start scheduled time in one processing facility.
本発明によれば、停止した加工設備が次の加工のために準備作業が行われる準備時間中において、他の加工設備が停止した際に、その加工設備が停止状態のまま放置されることによる稼働効率の低下を防止することができる。これにより、高い稼働効率で線材に加工を施すことができる。 According to the present invention, when the other processing equipment is stopped during the preparation time in which the stopped processing equipment is prepared for the next processing, the processing equipment is left in a stopped state. A reduction in operating efficiency can be prevented. Thereby, it can process to a wire with high operation efficiency.
以下、本発明に係る線材の加工方法の実施の形態の例を、図面を参照して説明する。
図１に示すように、本実施形態に係る線材の加工方法が適用される施設１は、複数の製造設備（加工設備）１１を備えている。また、施設１は、制御装置２を備えており、この制御装置２によって各製造設備１１が制御される。
Hereinafter, an example of an embodiment of a wire rod processing method according to the present invention will be described with reference to the drawings.
As shown in FIG. 1, a facility 1 to which a wire rod processing method according to this embodiment is applied includes a plurality of manufacturing facilities (processing facilities) 11. Further, the facility 1 includes a control device 2, and each manufacturing facility 11 is controlled by the control device 2.
図２に示すように、製造設備１１は、例えば、導体に樹脂を被覆した電線（加工線）Ｃを製造するものであり、導体となる線材１０が巻回された繰り出しボビン１２を有し、この繰り出しボビン１２から線材１０が繰り出される。 As shown in FIG. 2, the manufacturing facility 11 is, for example, for manufacturing an electric wire (processed wire) C in which a conductor is coated with a resin, and has a feeding bobbin 12 around which a wire 10 serving as a conductor is wound, The wire 10 is fed out from the feeding bobbin 12.
線材１０は、製造する電線Ｃの種類に応じて異なる。例えば、絶縁電線を製造する場合の線材１０は導体であり、同軸ケーブルを製造する場合の線材１０は、中心導体の周囲に絶縁体及び外部導体が順に設けられたシールドコア線の場合がある。なお、導体を樹脂で被覆した絶縁電線に樹脂からなるジャケット層を被覆させる場合では、線材１０は絶縁電線である。 The wire 10 differs depending on the type of the electric wire C to be manufactured. For example, the wire 10 in the case of manufacturing an insulated wire may be a conductor, and the wire 10 in the case of manufacturing a coaxial cable may be a shielded core wire in which an insulator and an outer conductor are sequentially provided around a center conductor. In addition, when the jacket layer which consists of resin is covered with the insulated wire which coat | covered the conductor with resin, the wire 10 is an insulated wire.
繰り出しボビン１２の下流側には、ガイドローラ１３が設けられ、繰り出しボビン１２から繰り出される線材１０は、ガイドローラ１３に掛けられて下流側の押出機１４へ導かれる。 A guide roller 13 is provided on the downstream side of the feeding bobbin 12, and the wire 10 fed from the feeding bobbin 12 is hung on the guide roller 13 and guided to the extruder 14 on the downstream side.
押出機１４は、線材１０が通過するクロスヘッド１５と、樹脂（ペレット）を貯留するホッパ１６とを有しており、ホッパ１６に投入された樹脂は、シリンダ（図示省略）へ送られ、シリンダにおいて溶融される。この押出機１４は、内部にスクリュー（図示省略）を有しており、スクリューが回転することによってシリンダの溶融樹脂がクロスヘッド１５へ送り込まれ、クロスヘッド１５から樹脂が押し出される。したがって、押出機１４では、スクリューの回転によってクロスヘッド１５から押し出される樹脂の押出流量が決定される。線材１０がクロスヘッド１５を通過する際に、クロスヘッド１５から押し出される樹脂を牽引して線材１０の周囲に樹脂が被覆されて電線Ｃとされる。 The extruder 14 has a cross head 15 through which the wire 10 passes and a hopper 16 that stores resin (pellet). The resin charged in the hopper 16 is sent to a cylinder (not shown), and the cylinder In the melt. The extruder 14 has a screw (not shown) inside, and when the screw rotates, the molten resin in the cylinder is fed into the cross head 15 and the resin is pushed out from the cross head 15. Therefore, in the extruder 14, the extrusion flow rate of the resin extruded from the cross head 15 is determined by the rotation of the screw. When the wire 10 passes through the cross head 15, the resin pushed out from the cross head 15 is pulled to cover the wire 10 with the resin to form the electric wire C.
押出機１４の下流側には、外径測定器２１が設けられており、外径測定器２１は、通過する電線Ｃの外径を測定する。外径測定器２１としては、例えば、レーザ光を用いて電線Ｃの外径を非接触で測定するレーザ式測定器が用いられる。 An outer diameter measuring device 21 is provided on the downstream side of the extruder 14, and the outer diameter measuring device 21 measures the outer diameter of the passing electric wire C. As the outer diameter measuring instrument 21, for example, a laser measuring instrument that measures the outer diameter of the electric wire C in a non-contact manner using laser light is used.
外径測定器２１の下流側には、冷却装置２２が設けられている。この冷却装置２２は、例えば、水冷式であり、冷却装置２２を通過する電線Ｃは、冷却装置２２によって冷却され、線材１０に被覆された樹脂が硬化される。 A cooling device 22 is provided on the downstream side of the outer diameter measuring device 21. The cooling device 22 is, for example, a water-cooled type, and the electric wire C passing through the cooling device 22 is cooled by the cooling device 22, and the resin coated on the wire 10 is cured.
冷却装置２２の下流側には、電線Ｃを引き取る引き取りローラ２３が設けられている。この引き取りローラ２３は、電線Ｃを所定の線速で引き取る。 On the downstream side of the cooling device 22, a take-up roller 23 for taking up the electric wire C is provided. The take-up roller 23 takes up the electric wire C at a predetermined linear velocity.
引き取りローラ２３の下流側には、蓄線機２５が設けられている。この蓄線機２５は、上下に配置された可動ローラ２６を有しており、これらの可動ローラ２６に、電線Ｃが巻回されている。可動ローラ２６は、水平方向に移動可能に支持されており、これらの可動ローラ２６が接近または離間して間隔が変動することにより、可動ローラ２６に巻き付けられて蓄線される電線Ｃの長さが調整される。なお、可動ローラ２６同士の間には、上下流側にそれぞれガイドローラ２７が設けられており、上流側のガイドローラ２７によって電線Ｃが上方の可動ローラ２６へ案内され、下流側のガイドローラ２７によって下方の可動ローラ２６からの電線Ｃが下流側へ案内される。 A storage device 25 is provided on the downstream side of the take-up roller 23. The accumulator 25 has movable rollers 26 arranged vertically, and an electric wire C is wound around these movable rollers 26. The movable roller 26 is supported so as to be movable in the horizontal direction, and the length of the electric wire C that is wound and stored around the movable roller 26 when the movable roller 26 approaches or separates and the interval varies. Is adjusted. A guide roller 27 is provided between the movable rollers 26 on the upstream side and the downstream side, and the electric wire C is guided to the upper movable roller 26 by the upstream guide roller 27, and the downstream guide roller 27. Thus, the electric wire C from the lower movable roller 26 is guided downstream.
蓄線機２５の下流側にはガイドローラ２８が設けられ、このガイドローラ２８によって電線Ｃが巻き取りボビン２９へ案内される。巻き取りボビン２９は、電線Ｃを巻き取るボビンである。 A guide roller 28 is provided on the downstream side of the wire accumulator 25, and the electric wire C is guided to the take-up bobbin 29 by the guide roller 28. The winding bobbin 29 is a bobbin that winds up the electric wire C.
上記の製造設備１１において、押出機１４の下流側の電線Ｃが巻き取りボビン２９に巻き取られるまでの電線Ｃのパスラインは、数十ｍ以上であり、例えば約１００ｍである。 In the manufacturing equipment 11 described above, the path line of the electric wire C until the electric wire C on the downstream side of the extruder 14 is wound around the winding bobbin 29 is several tens of meters, for example, about 100 m.
上記の製造設備１１では、引き取りローラ２３によって線材１０を引き取ることにより、繰り出しボビン１２から線材１０を繰り出させ、押出機１４のクロスヘッド１５へ線材１０を通過させる。これにより、線材１０の周囲にはクロスヘッド１５から樹脂が押し出されて、線材１０の周囲に樹脂が被覆された電線Ｃが製造される。 In the manufacturing equipment 11 described above, the wire 10 is drawn from the take-out bobbin 12 by taking up the wire 10 by the take-up roller 23, and the wire 10 is passed through the cross head 15 of the extruder 14. As a result, the resin is pushed out from the cross head 15 around the wire 10, and the electric wire C in which the resin is coated around the wire 10 is manufactured.
押出機１４の下流側では、電線Ｃの外径を外径測定器２１で測定する。製造される電線Ｃの外径を一定に保つために、外径測定器２１の測定結果に基づいて、引き取りローラ２３または押出機１４のスクリューの駆動制御を行い、線材１０の線速または押し出される樹脂量を制御する外径制御を行う。
引き取りローラ２３によって引き取られる電線Ｃは、蓄線機２５の可動ローラ２６に巻回されて蓄線され、その後、巻き取りボビン２９に巻き取られる。
On the downstream side of the extruder 14, the outer diameter of the electric wire C is measured by the outer diameter measuring device 21. In order to keep the outer diameter of the electric wire C to be manufactured constant, the drive control of the take-up roller 23 or the screw of the extruder 14 is performed based on the measurement result of the outer diameter measuring device 21, and the wire speed of the wire rod 10 is pushed out. Perform outer diameter control to control the amount of resin.
The electric wire C taken up by the take-up roller 23 is wound and stored on the movable roller 26 of the accumulator 25, and then taken up on the take-up bobbin 29.
上記の製造設備１１を備えた施設１で電線Ｃを製造する場合、まず、線材１０を巻いた繰り出しボビン１２を配置させ、線材１０をパスラインへ引き出してセットする。そして、製造する電線Ｃの長さである要求長Ｌ１のデータを製造装置２へ、入力部（図示省略）から入力する。この要求長Ｌ１は、繰り出しボビン１２に巻回された線材１０の投入長と同一またはそれよりも短い長さとなる。 When the electric wire C is manufactured in the facility 1 having the manufacturing equipment 11 described above, first, the feeding bobbin 12 around which the wire rod 10 is wound is disposed, and the wire rod 10 is pulled out and set to the pass line. And the data of the required length L1 which is the length of the electric wire C to manufacture are input into the manufacturing apparatus 2 from an input part (illustration omitted). This required length L1 is equal to or shorter than the input length of the wire 10 wound around the feeding bobbin 12.
次に、押出機１４のホッパ１６に樹脂材料を供給し、製造設備１１を稼働させる。このようにすると、繰り出しボビン１２から繰り出される線材１０の外周に、押出機１４で加熱して溶融された樹脂が押出被覆されて電線Ｃとされ、巻き取りボビン２９に巻き取られる。そして、この巻き取りボビン２９で巻き取られた電線Ｃの巻取長Ｌ２が計測され、制御装置２へ送信される。 Next, the resin material is supplied to the hopper 16 of the extruder 14 and the manufacturing facility 11 is operated. In this way, the outer periphery of the wire rod 10 fed from the feeding bobbin 12 is coated with the resin heated and melted by the extruder 14 to be the electric wire C, and is wound around the winding bobbin 29. Then, the winding length L <b> 2 of the electric wire C wound up by the winding bobbin 29 is measured and transmitted to the control device 2.
その後、線速を上げて定常線速Ｖでの加工を行う定常状態とし、この定常状態での自動運転とする。このようにすると、作業者は、この製造設備１１での作業が一旦終了することとなり、製造設備１１に異常が生じない限り、自動運転が継続される。 Thereafter, the steady state in which the line speed is increased and machining at the steady line speed V is performed, and the automatic operation in the steady state is performed. If it does in this way, an operator will once complete | finish work in this manufacturing equipment 11, and automatic operation will be continued as long as abnormality does not arise in the manufacturing equipment 11. FIG.
このとき、制御装置２は、製造設備１１からの計測データに基づいて、電線Ｃの残長Ｌ３を算出する。この残長Ｌ３は、製造指示による製造する電線Ｃの要求長Ｌ１から製造された電線Ｃの巻取長Ｌ２を減算した長さ（Ｌ３＝Ｌ１−Ｌ２）である。 At this time, the control device 2 calculates the remaining length L3 of the electric wire C based on the measurement data from the manufacturing facility 11. This remaining length L3 is a length (L3 = L1-L2) obtained by subtracting the winding length L2 of the produced electric wire C from the required length L1 of the produced electric wire C according to the production instruction.
さらに、制御装置２は、算出した残長Ｌ３から自動運転予定残時間ｔ１を算出する。この自動運転予定残時間ｔ１は、残長Ｌ３を線速Ｖで割った時間（ｔ１＝Ｌ３／Ｖ）である。なお、自動運転の停止前から電線Ｃの線速は次第に減速されることとなり、自動運転予定残時間ｔ１は、単純に残長Ｌ３を線速Ｖで割った時間よりも長くなるが、この減速によって長くなる時間は、１，２分程度の微細な時間であるので、自動運転予定残時間ｔ１へ考慮しなくてもあまり影響はない。 Further, the control device 2 calculates the scheduled automatic driving remaining time t1 from the calculated remaining length L3. This scheduled automatic operation remaining time t1 is a time (t1 = L3 / V) obtained by dividing the remaining length L3 by the linear velocity V. The linear speed of the electric wire C is gradually decelerated before the automatic operation is stopped, and the automatic operation scheduled remaining time t1 is longer than the time obtained by simply dividing the remaining length L3 by the linear speed V. Since the time lengthened by the above is a minute time of about 1 or 2 minutes, there is not much influence even if the automatic operation scheduled remaining time t1 is not taken into consideration.
そして、制御装置２は、この自動運転予定残時間ｔ１に基づいて、自動運転による電線Ｃの製造が終了する時刻である加工終了予定時刻Ｔ１を予測する。 Then, the control device 2 predicts a scheduled processing end time T1, which is a time at which the manufacture of the electric wire C by the automatic operation ends based on the scheduled automatic operation remaining time t1.
制御装置２は、さらに加工終了予定時刻Ｔ１に準備時間ｔ２を加算した加工開始予定時刻Ｔ２を算出する。この準備時間ｔ２は、自動運転の終了後における次に製造する電線Ｃの製造の準備に要する時間であり、例えば、ダイス等の変更を行うための型替え及び清掃作業に要する時間、または被覆する樹脂の色等の変更に伴う樹脂変更を行うための色替え作業に要する時間である。 The control device 2 further calculates a scheduled machining start time T2 obtained by adding the preparation time t2 to the scheduled machining end time T1. This preparation time t2 is the time required for preparation for manufacturing the electric wire C to be manufactured next after the end of the automatic operation, for example, the time required for mold change and cleaning work for changing the die or the like, or covering. This is the time required for the color change operation for changing the resin accompanying the change in the color of the resin.
加工終了予定時刻Ｔ１及び加工開始予定時刻Ｔ２は、制御装置２のディスプレイ等の表示部３に表示される。 The scheduled machining end time T1 and the scheduled machining start time T2 are displayed on the display unit 3 such as a display of the control device 2.
施設１の稼動中、ある一つの製造設備１１の加工開始予定時刻Ｔ２前に、他の製造設備１１が加工終了予定時刻Ｔ１となって自動運転が終了する、干渉停止と呼ばれる状況が発生する場合がある。このような干渉停止が生じる場合、制御装置２は、施設１の管理者へＰＨＳ（Personal Handyphone System）等の通信手段によって、その旨を通知して警報する。なお、管理室に設置された制御装置２の表示部３には、各製造設備１１の運転状況、加工終了予定時刻Ｔ１及び加工開始予定時刻Ｔ２が表示される。したがって、この制御装置２の表示部３の表示によって管理者へ干渉停止が発生することを把握させても良い。 When the facility 1 is in operation, a situation called interference stop occurs in which another manufacturing facility 11 reaches the processing end scheduled time T1 and the automatic operation ends before the processing start scheduled time T2 of one manufacturing facility 11. There is. When such an interference stop occurs, the control device 2 notifies the alarm to the manager of the facility 1 by a communication means such as PHS (Personal Handyphone System). In addition, on the display unit 3 of the control device 2 installed in the management room, the operating status of each manufacturing facility 11, the scheduled processing end time T1, and the scheduled processing start time T2 are displayed. Accordingly, the display of the display unit 3 of the control device 2 may cause the administrator to grasp that the interference stop occurs.
干渉停止が生じることを把握した管理者は、自動運転中の他の製造設備１１の作業者へ連絡し、干渉停止する製造設備１１へ配置させる。 The manager who grasps that the interference stop occurs contacts the worker of the other manufacturing equipment 11 during the automatic operation and arranges it on the manufacturing equipment 11 where the interference stops.
これにより、停止した製造設備１１に対して次の加工のための準備作業が行われる準備時間ｔ２中において、他の製造設備１１が停止した際に、その製造設備１１が停止状態のまま放置されることによる稼働効率の低下を防止することができる。したがって、施設１において製造設備１１の数よりも作業者の数が少ない場合であっても、干渉停止となる製造設備１１の停止状態での放置を極力抑えることができ、施設１の高稼働率化を図ることができる。 As a result, when another manufacturing facility 11 is stopped during the preparation time t2 during which preparation work for the next processing is performed on the stopped manufacturing facility 11, the manufacturing facility 11 is left in a stopped state. It is possible to prevent a decrease in operating efficiency due to the above. Therefore, even if the number of workers in the facility 1 is smaller than the number of manufacturing equipments 11, it is possible to suppress the leaving of the manufacturing equipment 11 that stops interference as much as possible, and the high operating rate of the facility 1. Can be achieved.
なお、製造設備１１が途中で異常停止する場合がある。その場合には、次のように対応する。
（１）第一の製造設備１１が最初に自動運転終了により停止する予定であったが、異常停止してしまった場合；
異常停止の第一の製造設備１１は、干渉停止の制御の対象外とし、二番目に自動運転終了による停止予定であった第二の製造設備１１の停止作業中における他の製造設備１１の干渉停止の有無を算出し直す。
In some cases, the manufacturing equipment 11 stops abnormally. In that case, it respond | corresponds as follows.
(1) If the first manufacturing facility 11 was originally scheduled to stop due to the end of automatic operation, but stopped abnormally;
The first manufacturing facility 11 that is abnormally stopped is not subject to interference stop control, and the second manufacturing facility 11 that was scheduled to stop second due to the end of automatic operation is interfering with other manufacturing facilities 11. Recalculate whether there is a stop.
（２）第一の製造設備１１が二番目以降に自動運転終了により停止する予定であったが、異常停止してしまった場合；
先に自動運転終了によって停止する予定の第二の製造設備１１の停止作業中に、異常停止の第一の製造設備１１が自動運転の終了によって停止する予定であったのであれば、その第一の製造設備１１を干渉停止の対象外として作業者の配置を取りやめる。また、この第一の製造設備１１は、異常停止であるので、対応可能な作業者が直ちにその第一の製造設備１１の復旧作業にあたる。
異常停止した第一の製造設備１１の異常停止がなかった場合の自動運転終了停止予定時刻が、先に停止予定であった第二の製造設備１１の停止作業中でない場合は、干渉停止が生じないので、通常通りの制御で対応する。
(2) If the first manufacturing equipment 11 was scheduled to stop after the second automatic operation, but stopped abnormally;
If the first manufacturing facility 11 that is abnormally stopped is scheduled to be stopped by the end of the automatic operation during the stop operation of the second manufacturing facility 11 that is scheduled to be stopped by the end of the automatic operation first, the first The manufacturing facility 11 is excluded from the interference stop target and the worker is no longer placed. In addition, since the first manufacturing facility 11 is abnormally stopped, a worker who can respond immediately recovers the first manufacturing facility 11.
If the scheduled stop time of the automatic operation end when there is no abnormal stop of the first manufacturing facility 11 that has stopped abnormally is not during the stop operation of the second manufacturing facility 11 that was scheduled to stop first, an interference stop occurs. Because there is not, it responds by the usual control.
次に、１号機から４号機の４つの製造設備１１Ａ〜１１Ｄを備えた施設１を例示して具体例を説明する。
図３は、製造設備１１Ａ〜１１Ｄの稼働状況を示しており、設備稼働の残時間の短い順に上方側から並べて記載されている。
Next, a specific example will be described by exemplifying the facility 1 including the four manufacturing facilities 11A to 11D of the first to fourth units.
FIG. 3 shows the operation status of the manufacturing facilities 11 </ b> A to 11 </ b> D, which are listed from the upper side in ascending order of the remaining time of operation of the facility.
図３に示すように、２号機（製造設備１１Ｂ）は、３０分後に自動運転が終了して停止する。その停止後、押出機１４のクロスヘッド１５のダイス等の変更を行うための型替え及び清掃作業が行われる。そして、この２号機では、自動運転の終了後、次に製造する電線Ｃの製造の準備に要する準備時間ｔ２は、６０分とされている。 As shown in FIG. 3, the second unit (manufacturing equipment 11B) stops after 30 minutes and the automatic operation ends. After the stop, mold change and cleaning work for changing the die of the crosshead 15 of the extruder 14 and the like are performed. And in this No. 2 machine, after completion | finish of automatic operation, the preparation time t2 required for preparation of manufacture of the electric wire C manufactured next is set to 60 minutes.
１号機（製造設備１１Ａ）は、４５分後に自動運転が終了して停止する。その停止後、被覆する樹脂の色等の変更に伴う樹脂変更を行うための色替え作業が行われる。そして、この１号機では、自動運転の終了後、次に製造する電線Ｃの製造の準備に要する準備時間ｔ２は、１５分とされている。 The first machine (manufacturing equipment 11A) stops after 45 minutes and automatic operation ends. After the stop, a color change operation is performed to change the resin accompanying a change in the color or the like of the resin to be coated. And in this 1st machine, after completion | finish of an automatic operation, the preparation time t2 required for preparation of manufacture of the electric wire C manufactured next is set to 15 minutes.
３号機（製造設備１１Ｃ）は、９０分後に自動運転が終了して停止する。その停止後、被覆する樹脂の色等の変更に伴う樹脂変更を行うための色替え作業が行われる。そして、この３号機においても、自動運転の終了後、次に製造する電線Ｃの製造の準備に要する準備時間ｔ２は、１５分とされている。 The third machine (manufacturing equipment 11C) stops after 90 minutes and automatic operation ends. After the stop, a color change operation is performed to change the resin accompanying a change in the color or the like of the resin to be coated. And also in this No. 3 machine, after completion | finish of an automatic driving | operation, the preparation time t2 required for preparation of manufacture of the electric wire C manufactured next is set to 15 minutes.
４号機（製造設備１１Ｄ）は、１００分後に自動運転が終了して停止する。その停止後、被覆する樹脂の色等の変更に伴う樹脂変更を行うための色替え作業が行われる。そして、この３号機においても、自動運転の終了後、次に製造する電線Ｃの製造の準備に必要な準備時間ｔ２は、１５分とされている。 Unit 4 (manufacturing facility 11D) stops after 100 minutes of automatic operation. After the stop, a color change operation is performed to change the resin accompanying a change in the color or the like of the resin to be coated. And also in this No. 3 machine, after completion | finish of an automatic operation, the preparation time t2 required for preparation of manufacture of the electric wire C manufactured next is set to 15 minutes.
上記のような稼働状況では、まず、２号機が３０分後に最初に自動運転が終了して停止し、その後の６０分間の準備時間ｔ２の間に、１号機と３号機が自動運転の終了により停止する。したがって、上記稼働状況では、１号機と３号機とが、干渉停止することとなる。 In the operating situation as described above, first, the automatic operation of the second unit is terminated and stopped after 30 minutes, and during the subsequent 60-minute preparation time t2, the first and third units are Stop. Therefore, in the above operating situation, the No. 1 machine and the No. 3 machine will stop interference.
図４は、上記の稼働状況における制御装置２の表示部３の表示画像を示している。図４に示すように、表示部３には、各号機の製造設備１１Ａ〜１１Ｄの自動運転予定残時間ｔ１及び各準備時間ｔ２が表示されている。そして、この表示部３の表示画像において、干渉停止が予測される１号機と３号機の準備時間ｔ２の表示部分では、その表示部分を囲う枠部が他の表示部分を囲う枠部よりも黄枠で点滅強調表示される。 FIG. 4 shows a display image on the display unit 3 of the control device 2 in the above-described operation state. As shown in FIG. 4, the display unit 3 displays the scheduled automatic operation remaining time t1 and the preparation times t2 of the manufacturing facilities 11A to 11D of each unit. In the display image of the display unit 3, in the display part of the preparation time t <b> 2 of Unit 1 and Unit 3 where interference stop is predicted, the frame part surrounding the display part is yellower than the frame part surrounding the other display parts. The frame is highlighted with blinking.
また、このように、１号機と３号機とに干渉停止が予測されると、制御装置２から管理者の通信端末へ通知が送信され、通信端末の表示にその旨が表示される。 In addition, when an interference stop is predicted between Unit 1 and Unit 3 as described above, a notification is transmitted from the control device 2 to the administrator's communication terminal, and this is displayed on the display of the communication terminal.
これにより、管理者は、通信端末の表示または制御装置２の表示部３の表示から、１号機と３号機に、干渉停止が予測されることを把握することができる。したがって、管理者は、１号機及び３号機が干渉停止する際に、他の製造設備で非作業状態の作業者へ連絡し、干渉停止する１号機及び３号機へ配置させ、干渉停止時に迅速に対応させることができる。２号機の型替え作業終了予定時刻が３号機の停止予定時刻であるので、２号機の作業者に型替え作業直後に３号機の作業を開始させるようにしてもよい。 Thereby, the administrator can grasp that the interference stop is predicted for the first and third machines from the display of the communication terminal or the display of the display unit 3 of the control device 2. Therefore, when Unit 1 and Unit 3 stop interference, the administrator will contact non-working workers at other manufacturing facilities and place them in Unit 1 and Unit 3 where interference will stop, and promptly when the interference stops Can be matched. Since the scheduled end time for the remodeling operation of the second unit is the scheduled stop time for the third unit, the operator of the second unit may start the operation of the third unit immediately after the remodeling operation.
このように、干渉停止する製造設備１１が停止状態のまま放置されることによる施設１の全体の稼働効率の低下を防止することができ、高い稼働効率で線材１０に加工を施すことができる。 In this way, it is possible to prevent the overall operating efficiency of the facility 1 from being lowered due to the manufacturing equipment 11 that stops interference being left in a stopped state, and the wire 10 can be processed with high operating efficiency.
なお、上記実施形態では、線材１０に対して樹脂を押出被覆する加工を施して電線Ｃを製造する場合を例示して説明したが、本発明はこれに限らない。 In the above-described embodiment, the case where the wire C is manufactured by subjecting the wire 10 to extrusion coating is described, but the present invention is not limited thereto.
