Description

本発明は、トロリーシステムに用いられる非接触式給電装置に関する。   The present invention relates to a contactless power feeding device used in a trolley system.

従来、走行式ホイストや搬送台車などの移動体と、この移動体に電力を供給する給電装置と、を備えるトロリーシステムがある。給電装置は、移動体を走行させるレールに沿って配索した給電線と移動体に設けた受電子との間で電力を受け渡しするようになっており、受電子で受け取った電力を移動体に供給するようになっている。給電装置としては、受電子にブラシが採用され、このブラシが給電線に常時接触する接触式給電装置が広く用いられている（例えば、特許文献１参照）。   2. Description of the Related Art Conventionally, there is a trolley system that includes a moving body such as a traveling hoist or a carriage and a power supply device that supplies electric power to the moving body. The power supply device is configured to transfer power between a power supply line routed along a rail on which the mobile body travels and an electron receiver provided on the mobile body, and the power received by the power receiver is transferred to the mobile body. It comes to supply. As a power supply device, a brush is used for receiving electrons, and a contact-type power supply device in which this brush is always in contact with a power supply line is widely used (for example, see Patent Document 1).

ところが、接触式給電装置では、ブラシが給電線に常時接触しつつ移動するため、ブラシや給電線に摩耗が発生して定期的に交換する必要があり、ランニングコストが高いものとなる。   However, in the contact-type power supply device, since the brush moves while always in contact with the power supply line, the brush and the power supply line are worn out and must be periodically replaced, resulting in a high running cost.

このため、近年では、給電線に高周波の電流を流して、その給電線の周りに発生する磁界による電磁誘導によって、その給電線に非接触状態で近接させた受電子に誘導電流を発生させるようにした非接触式給電装置が提案されている（例えば、特許文献２参照）。
特開平９−２５５２７９号公報（第３頁、図１） 特開平１１−４５０２号公報（第３頁、図２） For this reason, in recent years, a high-frequency current is caused to flow through a power supply line, and an induced current is generated in a received electron that is brought close to the power supply line in a non-contact state by electromagnetic induction caused by a magnetic field generated around the power supply line. There has been proposed a non-contact type power feeding device (see, for example, Patent Document 2).

本発明の第１の実施形態について図面を参照しつつ詳細に説明する。図１〜図８は、本発明の第１の実施形態にかかる非接触式給電装置を用いたトロリーシステムを示し、図１は、トロリーシステムを示す概略構成図、図２は、図１中II−II線に沿った拡大断面図、図３は、給電線の接続端部を示す拡大斜視図、図４は、給電線を接続具によって接続した状態を示す拡大斜視図、図５は、接続具の接続本体部を示す拡大斜視図、図６は、給電線の接続端部に接続具の接続本体部を取り付けようとする状態を示す拡大斜視図、図７は、給電線の接続端部に接続具の接続本体部を取り付けた状態を示す拡大斜視図、図８は、給電線の接続端部に取り付けた接続具の接続本体部を正規状態に配置した状態を示す拡大斜視図である。   A first embodiment of the present invention will be described in detail with reference to the drawings. 1 to 8 show a trolley system using a non-contact power feeding device according to a first embodiment of the present invention, FIG. 1 is a schematic configuration diagram showing the trolley system, and FIG. 2 is II in FIG. FIG. 3 is an enlarged perspective view showing the connection end of the feeder line, FIG. 4 is an enlarged perspective view showing a state where the feeder line is connected by a connector, and FIG. FIG. 6 is an enlarged perspective view showing a state in which the connection body portion of the connection tool is to be attached to the connection end portion of the feeder line, and FIG. 7 is a connection end portion of the feed line. FIG. 8 is an enlarged perspective view showing a state in which the connection main body part of the connection tool attached to the connection end of the feeder line is arranged in a normal state. .

図１に示すように、トロリーシステム１は、図示省略した移動体用レールに沿って移動可能な移動体３と、この移動体３に電力を供給する非接触式給電装置４と、を備えている。   As shown in FIG. 1, the trolley system 1 includes a moving body 3 that can move along a moving body rail (not shown), and a non-contact power supply device 4 that supplies electric power to the moving body 3. Yes.

移動体３を案内する移動体用レールは、図示省略した工場や倉庫などの躯体に固定して設置される。そして、移動体３は、非接触式給電装置４から供給される電力によってモータ３１を駆動して、所定の仕事、例えば移動体用レールに沿った走行や図示省略したチェーンブロックの作動、搬送ベルトの駆動などを行う。   The moving body rail for guiding the moving body 3 is fixedly installed on a housing such as a factory or a warehouse not shown. Then, the moving body 3 drives the motor 31 with the electric power supplied from the non-contact type power feeding device 4 to drive a predetermined work, for example, travel along the rail for the moving body, the operation of the chain block (not shown), the conveying belt. And so on.

非接触式給電装置４は、細長い板状の配索部材２と、この配索部材２に配索され電源５から高周波の電流が流される相互に連結された複数の給電線６と、移動体３に従動し給電線６から得た電力を移動体３に供給する受電装置７と、を備える。   The non-contact type power feeding device 4 includes an elongated plate-shaped wiring member 2, a plurality of mutually connected power feeding wires 6 that are routed on the wiring member 2 and are supplied with a high-frequency current from a power source 5, and a moving body 3 and a power receiving device 7 that supplies power obtained from the feeder 6 to the moving body 3.

受電装置７は、給電線６に対して非接触状態で移動体３に連結されており、移動体３に牽引されることで、配索部材２および給電線６に沿って移動する。この受電装置７は、給電線６を流れる電流による電磁誘導によって得た電力を移動体３に供給する。   The power receiving device 7 is connected to the moving body 3 in a non-contact state with respect to the power supply line 6, and moves along the routing member 2 and the power supply line 6 by being pulled by the mobile body 3. The power receiving device 7 supplies the moving body 3 with electric power obtained by electromagnetic induction using a current flowing through the feeder 6.

受電装置７は、給電線６に非接触状態で配置される受電子としてのコア７１、共振回路７２および定電圧回路７３を有している。   The power receiving device 7 includes a core 71, a resonance circuit 72, and a constant voltage circuit 73 as received electrons arranged in a non-contact state on the power supply line 6.

コア７１は、図２に示すように、給電線６を側方から跨るように断面ほぼＵ字状の外郭７１ｓを有し、その外郭７１ｓの内部には、給電線６の両側方に位置するように一対のコイル７１ｐ、７１ｍが対向配置されて電磁ピックアップが構成される。ここで、コイル７１ｐ、７１ｍは、給電線６に可能な限り近接させることが好ましい。そして、電源５から給電線６に高周波の電流が供給されることにより、給電線６の周囲に、供給された高周波の電流の周波数に応じた磁界ＭＦの発生・減衰現象が発生し、それが磁束密度の変化となってコイル７１ｐ、７１ｍに誘導電流が発生する（電磁誘導）。   As shown in FIG. 2, the core 71 has an outer shell 71 s having a substantially U-shaped cross section so as to straddle the feeder wire 6 from the side, and is located on both sides of the feeder wire 6 in the outer shell 71 s. Thus, a pair of coils 71p and 71m are arranged to face each other to constitute an electromagnetic pickup. Here, the coils 71p and 71m are preferably as close as possible to the feeder line 6. Then, when a high frequency current is supplied from the power source 5 to the power supply line 6, the generation / attenuation phenomenon of the magnetic field MF corresponding to the frequency of the supplied high frequency current occurs around the power supply line 6. As the magnetic flux density changes, an induced current is generated in the coils 71p and 71m (electromagnetic induction).

そして、受電装置７では、このようにしてコイル７１ｐ、７１ｍに発生した電流を、図１に示す共振回路７２で安定化した後、定電圧回路７３から移動体３に設けたインバータ３２に送る。移動体３では、インバータ３２でその電流を直流に変換しモータ３１に供給する。   In the power receiving device 7, the current generated in the coils 71 p and 71 m in this way is stabilized by the resonance circuit 72 shown in FIG. 1 and then sent from the constant voltage circuit 73 to the inverter 32 provided in the moving body 3. In the moving body 3, the current is converted into direct current by the inverter 32 and supplied to the motor 31.

給電線６は、図３に示すように、導体部６１と、この導体部６１を中心部に埋設した絶縁部６２と、によって一定長さの長尺体として形成される。給電線６は、配索される長さに応じて複数本を繋いで使用される。絶縁部６２は、柔軟な合成樹脂などで断面円形状に形成され、この絶縁部６２に管状に形成した導体部６１をインサートして押出し成型することにより、一定長さの給電線６を連続的に成形できる。   As shown in FIG. 3, the feeder 6 is formed as a long body having a fixed length by a conductor 61 and an insulating part 62 in which the conductor 61 is embedded in the center. The feeder line 6 is used by connecting a plurality of feeder lines according to the length of wiring. The insulating part 62 is formed in a circular cross section with a flexible synthetic resin or the like, and the conductor part 61 formed into a tubular shape is inserted into the insulating part 62 and extruded to continuously feed the power supply line 6 having a certain length. Can be molded.

そして、図１に示すように、給電線６同士は、配索部材２に沿って配索される際、ジョイナー８、Ｌ型ジョイナー８Ａ、エンドジョイナー８Ｂなどの接続具を介して繋げられる。   As shown in FIG. 1, when the feeders 6 are routed along the routing member 2, the feeder wires 6 are connected via a connecting tool such as a joiner 8, an L-type joiner 8 </ b> A, and an end joiner 8 </ b> B.

ここで、配索部材２には、移動体３の予め設定した走行経路に沿って直線部分、折曲部分および湾曲部分などが形成され、これに伴って給電線６も配索部材２の直線部分は直線状配索部分６Ａとなり、折曲部分は折曲状配索部分６Ｂとなり、かつ、湾曲部分は湾曲状配索部分６Ｃとなる。したがって、給電線６の直線状配索部分６Ａはジョイナー８によって接続され、湾曲状配索部分６ＣはＬ型ジョイナー８Ａによって接続される。また、給電線６は、往路側の線６ｍと復路側の線６ｎとがほぼ平行して配索されることになるが、それら両線６ｍ、６ｎの終端部同士はエンドジョイナー８Ｂで接続される。   Here, a straight portion, a bent portion, a curved portion, and the like are formed on the routing member 2 along a preset travel route of the moving body 3, and accordingly, the feeder 6 is also a straight line of the routing member 2. The portion becomes a straight routing portion 6A, the bent portion becomes a bent routing portion 6B, and the curved portion becomes a curved routing portion 6C. Therefore, the straight wiring portion 6A of the feeder 6 is connected by the joiner 8, and the curved wiring portion 6C is connected by the L-shaped joiner 8A. In addition, the feed line 6 is routed so that the forward line 6m and the return line 6n are substantially parallel to each other, but the end portions of both the lines 6m and 6n are connected by an end joiner 8B. The

給電線６は、電線ハンガー９によって配索部材２に取り付けられる。この電線ハンガー９によって、給電線６を配索部材２に沿わせて配索しつつ、給電線６の垂れ下がりを防止するようになっている。   The feeder 6 is attached to the routing member 2 by an electric wire hanger 9. The electric wire hanger 9 prevents the feed line 6 from hanging down while routing the feed line 6 along the routing member 2.

電線ハンガー９は、図２、図４に示すように、一対の保持アーム９ａ、９ｂと、これら保持アーム９ａ、９ｂの基端部同士を連結する連結部９ｃと、によってほぼコ字状に形成され、連結部９ｃが図示省略した結合手段を介して配索部材２と結合される。保持アーム９ａ、９ｂの先端部にはそれぞれ保持部９１、９１が設けられ、それら保持部９１、９１に給電線６ｍ、６ｎが挟み込むようにして保持される。   As shown in FIGS. 2 and 4, the wire hanger 9 is formed in a substantially U shape by a pair of holding arms 9a and 9b and a connecting portion 9c for connecting the base ends of the holding arms 9a and 9b. Then, the connecting portion 9c is coupled to the routing member 2 via coupling means (not shown). Holding portions 91 and 91 are provided at the distal ends of the holding arms 9a and 9b, respectively, and the feeders 6m and 6n are held between the holding portions 91 and 91, respectively.

給電線６同士を直線状に接続するジョイナー８は、図５、図６に示すように、一対の導体部６１、６１を接続する接続本体部８１を有している。接続本体部８１は、端部同士が相互に対面した一対の導体部６１、６１の側方からこれら導体部６１、６１に外装されてこれら導体部６１、６１を接続するようになっている。   As shown in FIGS. 5 and 6, the joiner 8 that connects the power supply lines 6 to each other in a straight line has a connection main body portion 81 that connects a pair of conductor portions 61 and 61. The connection main body 81 is externally attached to the conductor portions 61 and 61 from the side of the pair of conductor portions 61 and 61 whose end portions face each other so as to connect the conductor portions 61 and 61.

接続本体部８１は、銅板などの電気良導部材によって形成され、接続しようとする導体部６１、６１にそれぞれ挟着される一対の挟着部８２、８３が所定間隔をもって設けられる。それぞれの挟着部８２、８３は、閉じ方向の弾発力をもって対峙する接触片８２ａ、８２ｂおよび８３ａ、８３ｂを備え、それら接触片８２ａ、８２ｂおよび８３ａ、８３ｂは、給電線６の外側形状（円形状）にほぼ沿った円弧状に形成される。   The connection main body 81 is formed of an electrically conductive member such as a copper plate, and is provided with a pair of sandwiching portions 82 and 83 that are respectively sandwiched by the conductor portions 61 and 61 to be connected. Each clamping part 82, 83 is provided with contact pieces 82a, 82b and 83a, 83b that confront each other with a resilient force in the closing direction, and these contact pieces 82a, 82b and 83a, 83b are formed in the outer shape of the feeder 6 ( It is formed in an arc shape substantially along a circular shape.

また、接続本体部８１は、合成樹脂などの絶縁材料によって所定幅Ｗをもってほぼ直方体状に形成されるベース部８４に取り付けられ、このベース部８４の高さｈ方向の一端部から上述した挟着部８２、８３が突出される。これら挟着部８２、８３はベース部８４の内部に埋設された図示省略した連結部によって電気的に接続されている。   The connection main body 81 is attached to a base portion 84 formed in a substantially rectangular parallelepiped shape with a predetermined width W by an insulating material such as a synthetic resin, and the above-described sandwiching is performed from one end portion in the height h direction of the base portion 84. The parts 82 and 83 are projected. These clamping parts 82 and 83 are electrically connected by a connecting part (not shown) embedded in the base part 84.

そして、給電線６の接続時には、図６に示すように、接続しようとする給電線６、６（尚、本実施形態では片側の給電線６ｎ、６ｎによって示す）の端部に導体部６１、６１を所要長さ分だけ露出しておき、それら導体部６１、６１を一直線状に対面させた状態で配置する。そして、図６に示すように、突き合わせた導体部６１、６１の側方に接続本体部８１の挟着部８２、８３を配置して、図７に示すように、それら挟着部８２、８３を導体部６１、６１に押し込む。すると、挟着部８２、８３は、導体部６１、６１に押し込む際にそれら導体部６１、６１の外側に沿って一旦開いた後に弾発力をもって閉じることにより、各導体部６１、６１に挟着される。即ち、接続本体部８１は、一対の導体部６１、６１に外装されることで導体部６１、６１と結合するようになっている。   At the time of connecting the power supply line 6, as shown in FIG. 6, the conductor part 61, at the end of the power supply lines 6 and 6 to be connected (in this embodiment, indicated by one of the power supply lines 6n and 6n) 61 is exposed for the required length, and the conductor portions 61 and 61 are arranged in a state of facing in a straight line. Then, as shown in FIG. 6, the sandwiching portions 82 and 83 of the connection main body 81 are arranged on the sides of the abutted conductor portions 61 and 61, and as shown in FIG. Is pushed into the conductor portions 61, 61. Then, when the sandwiching portions 82 and 83 are pushed into the conductor portions 61 and 61, the sandwiching portions 82 and 83 are temporarily opened along the outer sides of the conductor portions 61 and 61 and then closed with elasticity, thereby sandwiching the conductor portions 61 and 61. Worn. That is, the connection main body 81 is coupled to the conductor portions 61 and 61 by being covered with the pair of conductor portions 61 and 61.

このとき、ベース部８４は、給電線６に対して配索部材２とは反対側に配置されており、図７中矢印Ｘに示すように、ベース部８４を、導体部６１、６１に挟着した挟着部８２、８３を中心として回転させて、図８に示すように、そのベース部８４を配索部材２側に配置する。   At this time, the base portion 84 is disposed on the side opposite to the wiring member 2 with respect to the feeder 6, and the base portion 84 is sandwiched between the conductor portions 61 and 61 as indicated by an arrow X in FIG. As shown in FIG. 8, the base portion 84 is arranged on the routing member 2 side by rotating around the sandwiched portions 82 and 83 that are worn.

また、ジョイナー８は、図４に示すように、一対の導体部６１、６１同士を接続した状態の接続本体部８１の外側を覆うカバー８５を有している。   In addition, as illustrated in FIG. 4, the joiner 8 includes a cover 85 that covers the outside of the connection main body 81 in a state where the pair of conductors 61 and 61 are connected to each other.

カバー８５は、図５に示すように、ベース部８４およびこのベース部８４から突出する接続本体部８１の挟着部８２、８３を覆うことができる長さＬ（図４参照）をもって断面コ字状に薄肉形成され、その開放側を、図８に示す状態で接続本体部８１側から被せた後、図４に示すように、ベース部８４を全体的に覆うようになっている。   As shown in FIG. 5, the cover 85 has a length L (see FIG. 4) that can cover the base portion 84 and the sandwiching portions 82 and 83 of the connection main body portion 81 protruding from the base portion 84.

At that time, as shown in FIGS. 4 and 6 to 8, the feeder 6 is near both sides of the attachment portion of the joiner 8. Is supported by the wiring member 2 via the wire hangers 9 and 9.

また、このように電線ハンガー９をジョイナー８の近傍に配置した際、図６〜図８に示すように、電線ハンガー９に、カバー８５で接続本体部８１を覆った際にそのカバー８５が係合する突起部９２を設けてある。   Further, when the wire hanger 9 is arranged in the vicinity of the joiner 8 as described above, the cover 85 is engaged with the wire hanger 9 when the connection main body 81 is covered with the cover 85 as shown in FIGS.

When the sandwiching portions 82 and 83 and the base portion 84 are covered, both end portions of the cover 85 are engaged with the protruding portions 92.

以上説明した本実施形態のトロリーシステム１によれば、非接触式給電装置４を用いたことにより、コア７１が給電線６に直接接触しないため、コア７１および給電線６の摩耗を無くして定期的なメンテナンスを軽減できる。   According to the trolley system 1 of the present embodiment described above, since the core 71 does not directly contact the power supply line 6 by using the non-contact power supply device 4, the core 71 and the power supply line 6 are not worn and the Maintenance can be reduced.

また、このようにコア７１と給電線６とが非接触となることにより、それら両者間の摺動抵抗が無くなって移動体３の走行速度を上昇できるとともに、給電線６が湾曲している箇所でも電力の受け取りが可能となる。更に、従来のように接触式のブラシを用いた場合に発生する電力スパークが無くなるとともに、電力の受け取り部分の露出が減少して安全性を向上できる。更にまた、水気の多い場所であってもショートを効率良く抑制できるとともに、接触不良による瞬時の停電状態を防止できる。   In addition, since the core 71 and the power supply line 6 are not in contact with each other in this manner, there is no sliding resistance between them, and the traveling speed of the moving body 3 can be increased, and the power supply line 6 is curved. But you can receive power. Furthermore, there is no power spark generated when a contact brush is used as in the prior art, and the exposure of the power receiving portion is reduced to improve safety. Furthermore, even in a place with a lot of moisture, a short circuit can be efficiently suppressed, and an instantaneous power failure due to poor contact can be prevented.

また、このように非接触式給電装置４を用いたトロリーシステム１にあって、本実施形態では、ジョイナー８によって給電線６同士を接続する際に、そのジョイナー８の接続本体部８１を、端部同士が相互に対面した一対の導体部６１、６１の側方からこれら導体部６１、６１に外装されてこれら導体部６１、６１を接続するようにしてある。従って、給電線６を配索した後にジョイナー８を取り付けることができ、給電線６の配索作業を容易にでき、よって、非接触式給電装置４の組立性の向上を図ることができる。   Further, in the trolley system 1 using the non-contact type power feeding device 4 as described above, in the present embodiment, when connecting the power feeding lines 6 to each other by the joiner 8, the connection main body 81 of the joiner 8 is connected to the end. The conductor portions 61 and 61 are covered from the side of the pair of conductor portions 61 and 61 facing each other so as to connect the conductor portions 61 and 61. Therefore, the joiner 8 can be attached after the feeding line 6 is routed, and the routing operation of the feeding line 6 can be facilitated. Therefore, the assemblability of the non-contact power feeding device 4 can be improved.

また、本実施形態では、接続本体部８１は、一対の導体部６１、６１に外装されることで導体部６１、６１と結合するので、導体部６１、６１への接続本体部５１の取り付けをワンタッチで行なうことができ、ジョイナー８の取付け作業が簡単になる。   Moreover, in this embodiment, since the connection main-body part 81 is couple | bonded with the conductor parts 61 and 61 by covering with a pair of conductor parts 61 and 61, attachment of the connection main-body part 51 to the conductor parts 61 and 61 is carried out. This can be done with a single touch, and the joiner 8 can be easily attached.

また、本実施形態にあっては、ジョイナー８は、一対の導体部６１同士を接続した状態の接続本体部８１の外側を覆うカバー８５を有する。従って、接続本体部８１が露出した状態となるのを防止できるため、安全性を向上できるとともに、スパークの発生を低減し、更には、水気の多い場所であってもショートを抑制できる。   Moreover, in this embodiment, the joiner 8 has the cover 85 which covers the outer side of the connection main-body part 81 of the state which connected a pair of conductor parts 61 comrades. Therefore, since it can prevent that the connection main-body part 81 will be in the exposed state, while improving safety | security, generation | occurrence | production of a spark can be reduced and also a short circuit can be suppressed even in a place with much moisture.

更に、給電線６は、ジョイナー８の取付部分の両側近傍が電線ハンガー９を介して配索部材２に支持してある。従って、ジョイナー８を導体部６１、６１の側方から挟着する際に給電線６の接続端部が撓むのを抑制できるため、ジョイナー８を容易にかつ確実に取り付けることができ、ひいては、給電線６の接続作業の能率化を図ることができる。   Further, the feeder 6 is supported on the wiring member 2 through the wire hanger 9 at both sides of the attachment portion of the joiner 8. Therefore, when the joiner 8 is clamped from the side of the conductor portions 61, 61, it is possible to suppress the bending of the connecting end portion of the feeder 6 so that the joiner 8 can be easily and reliably attached. Efficiency of connection work of the feeder 6 can be improved.

更にまた、電線ハンガー９にカバー８５が係合する突起部９２を設けてあるので、カバー８５で接続本体部８１およびベース部８４を覆った際に、そのカバー８５が電線ハンガー９の突起部９２に係合するため、ジョイナー８が回転するのを阻止することができる。   Furthermore, since the protruding portion 92 with which the cover 85 engages is provided on the wire hanger 9, when the connection main body portion 81 and the base portion 84 are covered with the cover 85, the cover 85 is the protruding portion 92 of the wire hanger 9. Therefore, it is possible to prevent the joiner 8 from rotating.

次に、本発明の第２の実施形態について図面を参照しつつ詳細に説明する。図９は、本実施形態にかかる非接触式給電装置の一部を示す拡大斜視図、図１０は、本実施形態にかかる非接触式給電装置の配索部材ユニットを示す斜視図、図１１は、本実施形態にかかる配索部材ユニット同士を連結した状態を示す斜視図、図１２は、本実施形態にかかる給電線の接続端部に接続具の接続本体部を取り付けようとする状態を示す拡大斜視図である。なお、第１の実施形態と同じ部分は同一符号で示し、説明も省略する。   Next, a second embodiment of the present invention will be described in detail with reference to the drawings. 9 is an enlarged perspective view showing a part of the non-contact power feeding apparatus according to the present embodiment, FIG. 10 is a perspective view showing a wiring member unit of the non-contact power feeding apparatus according to the present embodiment, and FIG.
