図 1は、 紡績機械のスピンドル直接モータ駆動システムの個別モータと配線及 びその周辺の一般的なシステム図で、 図 1 ( a ) は個別モータ 3が誘導モータの 場合である。 スピンドルレール 1上のスピンドル 2に取付けられた個別モータ 3 には、 電力供給線 4から電力供給分岐線 6、 ブレーキ装置 1 0— 1に連動したス イッチ 1 0— 2を通して、 交流電力が供給される。 図 1 ( b ) は個別モータ 3が、 個別インバータ 9によって制御される場合である。 個別モータ 3には、 電力供給 線 4から電力供給分岐線 6、 個別インバータ 9、 さらに接続線 7を通して、 電力 が供給される。 また制御信号線 4 aから制御信号分岐線 6 aが個別インバータ 9 に接続される。 停止スィッチ 1 0— 3は、 個別インバータ 9にスピンドル個別停 止 Z始動を指令するものである。  Figure 1 is a general system diagram of the individual motors and wiring of the spindle direct motor drive system of the spinning machine and its surroundings. Figure 1 (a) shows the case where the individual motor 3 is an induction motor. AC power is supplied to the individual motor 3 mounted on the spindle 2 on the spindle rail 1 from the power supply line 4 through the power supply branch line 6 and the switch 10-2 linked to the brake device 10-1. You. FIG. 1B shows a case where the individual motor 3 is controlled by the individual inverter 9. Power is supplied to the individual motor 3 from the power supply line 4 through the power supply branch line 6, the individual inverter 9, and the connection line 7. Further, a control signal branch line 6a is connected to the individual inverter 9 from the control signal line 4a. The stop switches 1 0 to 3 command the individual inverter 9 to individually stop the spindle and to start the Z axis.
図 2と図 3は従来技術を示す。 図 2は、 図 1 ( a ) における電力供給のための 配線シス亍ムの従来例である。 樹脂製の配線ダク卜 8の中で、 裸銅バーの電力供 給線 4一 1、 4一 2、 4— 3が樹脂製のダクトケース 8— 1に埋設されるように して、 絶縁のための距離をおいて配置されている。  Figures 2 and 3 show the prior art. FIG. 2 is a conventional example of the wiring system for power supply in FIG. 1 (a). In the resin wiring duct 8, the bare copper bar power supply lines 4-1, 4-1, 2, 4-3 are buried in the resin duct case 8-1, and the insulation Are placed at a distance apart.
図 3は、 図 1 ( b ) における個別モータと配線及びその周辺の従来例である。 配線ダクト 8内には、 少なくとも 2本の電力供給線 4一 1、 4 - 2 (直流電力供 給の場合、 電力供給線は 2本である） と少なくとも 1本の制御信号線 4 a— 1が 絶緣のための距離をおいて配置され、 それらがスピンドルレール 1の下部に取付 けられている。 ハウジング 1 2内には、 個別インバータ 9、 停止スィッチ 1 0— 3、 制御部材 1 1と電力供給分岐線 4 a、 制御信号分岐線 6 a、 接続線 7などの 配線が納められ、 それらが個別モータ 3、 スピンドル 2の下部、 スピンドルレー ル 1及び配線ダクト 8を覆うように各々のスピンドル毎に取付けられている。 一般に、 紡績機械への供給電力は約 1 5〜5 0 k V A、 電源電圧は交流 2 0 0 V級、 4 0 0 V級であり、 機械の配線システムは、 相応の太い径と耐電圧を持つ 電線を使用する必要がある。 またスピンドル直接モータ駆動システムにおいて、 電力供給分岐点 5は充電部が露出している （以下、 裸充電部という） ので、 他の 相の電力供給分岐点 5との間は、 電圧に応じた絶縁のための距離以上離れていな ければならない。 さらに加えて、 この配線システムは、 図 2、 図 3のように人の 手が簡単に触れないように考慮した安全性を持つと共に、 風綿 （空中に浮遊する 微細な繊維の屑） が侵入しないような密閉構造を持つ必要がある。 このような理 由で、 スピンドル直接モータ駆動システムの配線システムは、 寸法が大きく、 機 械の内部にかなりの取付箇所と空間が必要であった。 FIG. 3 shows a conventional example of the individual motors and wirings and their peripherals in FIG. 1 (b). In the wiring duct 8, at least two power supply lines 4 1 and 4-2 (in the case of DC power supply, there are two power supply lines) and at least one control signal line 4a—1 Are arranged at a distance for clarity and they are mounted on the lower part of the spindle rail 1. Inside the housing 12 are the individual inverter 9, stop switch 10-3, control member 11 and power supply branch line 4a, control signal branch line 6a, connection line 7, etc. Wiring is housed, and they are attached to each spindle so that they cover the individual motor 3, the lower part of the spindle 2, the spindle rail 1 and the wiring duct 8. Generally, the power supplied to the spinning machine is about 15 to 50 kVA, the power supply voltage is AC 200 V class and 400 V class, and the wiring system of the machine must have a correspondingly large diameter and withstand voltage. It is necessary to use wires. Also, in the spindle direct motor drive system, the power supply branch point 5 has an exposed charged part (hereinafter referred to as a bare charged part), so it is insulated according to the voltage between the power supply branch point 5 of other phases and the power supply branch point 5. Must be at least as far apart as possible. In addition, this wiring system has safety as shown in Fig. 2 and Fig. 3 so that it cannot be easily touched by human hands, and fly wool (fine fiber debris floating in the air) enters. It is necessary to have a closed structure that does not. For this reason, the wiring system of the spindle direct motor drive system was large in size and required considerable mounting points and space inside the machine.
また図 3のように、 配線ダクト 8内の電力供給線 4上の電力供給分岐点 5から 個別モータ 3までの電力供給分岐線 6の途中に個別インバータ 9や制御部材 1 1 などが設置される塌合、 絶縁のための距離、 耐圧、 密閉構造を考慮した取付や配 線は複雑な構造になるものであった。  Also, as shown in Fig. 3, an individual inverter 9 and control members 11 are installed in the middle of the power supply branch line 6 from the power supply branch point 5 on the power supply line 4 in the wiring duct 8 to the individual motor 3. In this case, the installation and wiring in consideration of the distance for insulation, withstand voltage, and hermetic structure had a complicated structure.
本発明が解決しょうとする課題は、 個別インバータが必要な場合も含めて、 紡 緝機械のスピンドル直接モータ駆動シス亍ムの配線や装置の実装を小形で簡単な 構造にして、 システムのコストを低減することにある。 発明の開示  The problem to be solved by the present invention is to reduce the cost of the system, including the case where a separate inverter is required, by making the wiring and equipment of the spindle direct motor drive system of the spinning machine small and simple. Is to reduce it. Disclosure of the invention
第 1の構成上の特徴 First configuration feature
第 1に、 紡繽機械のスピンドル直接モータ駆動システムに係る発明において、 機械の長手方向に設置されるスピンドルレールに配列される複数のスピンドルと、 前記スピンドル毎に備付けられて前記スピンドルを個別に直接駆動するための複 数の個別モータを有し、 複数の前記個別モータに電力を供給するための少なくと も 2本の電力供給線を前記スピンドルレールに沿って配置し、 絶縁被覆部が部分 的に剥されて、 前記個別モータ毎に電力が供給されるところの、 前記各電力供給 線の電力供給分岐点が、 前記電力供給線の長手方向に、 少なくともそれぞれの前 記電力供給線間の電圧に応じた絶縁のための距離をとって、 相互に離れて位置す るような配線システムを構成することを特徴とする。 First, in the invention relating to a spindle direct motor drive system of a spinning machine, a plurality of spindles arranged on a spindle rail installed in the longitudinal direction of the machine, It has a plurality of individual motors for driving, and at least two power supply lines for supplying power to the plurality of individual motors are arranged along the spindle rail, and an insulating coating portion is partially provided. The power supply branch point of each of the power supply lines where power is supplied to each of the individual motors in the longitudinal direction of the power supply line, at least in front of each The present invention is characterized in that a wiring system is configured so that the power supply lines are separated from each other with a distance for insulation in accordance with the voltage between the power supply lines.
第 1の作用効果 First effect
第 1に、 それぞれの電力供給分岐点が、 前記電力供給線の長手方向に、 少なく ともそれぞれの前記電力供給線間の電圧に応じた絶縁のための距離をとって、 相 互に離れて位置するので、 被覆部で絶縁された互いの電力供給線を近接して配置 することができ、 配線のための空間を最小にできる作用効果がある。  First, the respective power supply branch points are located at a distance from each other in the longitudinal direction of the power supply lines, at least at a distance for insulation corresponding to the voltage between the respective power supply lines. Therefore, the power supply lines insulated by the covering portion can be arranged close to each other, and this has the effect of minimizing the space for wiring.
一般に、 個別モータが D Cブラシレスモータの場合は、 直流電力供給方式をと るので 2本の電力供給線が必要であり、 個別モータが誘導モータの場合は、 3相 交流電力供給方式をとるので、 3本の電力供給線が必要である。  In general, if the individual motor is a DC brushless motor, two power supply lines are required because the DC power supply method is used.If the individual motor is an induction motor, a three-phase AC power supply method is used. Three power supply lines are required.
第 2の構成上の特徴 Second structural feature
第 2に、 第 1の構成上の特徴に加えて、 前記各電力供給線が裸線で、 かつ前記 各電力供給線の被覆部が絶縁樹脂製ダクトで構成されることを特徴とする。 第 2の作用効果  Second, in addition to the features of the first configuration, each of the power supply lines is a bare wire, and a covering portion of each of the power supply lines is formed of an insulating resin duct. Second effect
第 2に、 第 1の作用効果に加えて、 各電力供給線が裸線であり、 かつ各電力供 給線の被覆部が絶縁樹脂製 （樹脂成形） ダクトそのものであるため、 電力供給線 をしつかり固定することができ、 また各電力供給線の被覆部を外す作業も必要な いので配線システムの組立作業は簡単である。 また絶縁樹脂製ダク卜にリブを立 てることにより、 絶縁のための沿面距離を確保することができるので、 電力供給 分岐点間の距離を小さくでき、 配線システムをより小形にすることができる。 第 3の構成上の特徴  Second, in addition to the first operation and effect, the power supply lines are bare wires, and the covering of each power supply line is an insulating resin (resin molded) duct itself. The wiring system can be easily fixed because there is no need to remove the covering of each power supply line. Also, by providing the ribs on the insulating resin duct, a creepage distance for insulation can be secured, so that the distance between the power supply branch points can be reduced, and the wiring system can be made more compact. Third configuration feature
第 3に、 第 1又は 2の構成上の特徴に加えて、 前記各電力供給線が、 前記個別 モータの前面のケースに設置される構成を特徴とする。  Thirdly, in addition to the features of the first or second configuration, each of the power supply lines is installed in a case on the front of the individual motor.
第 3の作用効果 Third effect
第 3に、 第 1又は 2の作用効果に加えて、 小形の配線シス亍ムを個別モータの 前面のケースに取付けることによって、 従来例のように配線ダクトの取付箇所や 取付空間を機械に設けることは、 全く必要ない。 また個別インバータなどが必要 な場合は、 個別インバータ、 電力供給分岐線及びその他を、 電力供給線と共に、 個別モータの前面のケース部に集中して実装することができる。 この集中的な実 装は、 接続線や制御部材を省略することができるため、 相乗的な小形化の効果を もたらすことになる。 図面の簡単な説明 Third, in addition to the first and second functions and effects, a small wiring system is mounted on the front case of the individual motor to provide a wiring duct installation location and mounting space on the machine as in the conventional example. Nothing is necessary. If individual inverters are required, the individual inverters, power supply branch lines, and others can be mounted together with the power supply lines on the case on the front of the individual motors. This intensive fruit Since the device can omit the connecting wires and control members, it has a synergistic downsizing effect. BRIEF DESCRIPTION OF THE FIGURES
