Description

本発明は、非接触給電を用いる移動体システムに関するものである。   The present invention relates to a mobile system using non-contact power feeding.

移動体システムの一つである一般的なエレベータは、かごから吊り下げられるテールコードと呼ばれる給電線により、かご内機器への給電を行っている。長行程化に伴いテールコードも長くなり質量も増大し、ある長さを超えると自重に耐えられなくなることが懸念される。そのため、超長行程に向けてはテールコードを無くしたエレベータが望まれ、かご内機器への給電が課題となる。かご内機器への給電方法としては、例えば特許文献１に示すように、移動方向にほぼ平行となるよう誘導線を張り、受電コイルにより電流を取り出す方法がある。かごの中央部を中心として左右対称の位置に１本ずつ誘導線を敷設し、受電ユニットを左右に１つずつ設け、かごが左右にずれてもほぼ一定の電流を取り出す方法が示されている。特許文献２ではエレベータカゴの上枠に設けられた２つの送電部からスライドドアへ給電する方法が示されている。   A general elevator, which is one of mobile system systems, supplies power to equipment in a car through a power supply line called a tail cord that is suspended from the car. Along with the increase in length, the tail cord becomes longer and the mass increases, and if it exceeds a certain length, there is a concern that it cannot withstand its own weight. Therefore, an elevator without a tail cord is desired for the ultra-long journey, and power supply to in-car equipment becomes a problem. As a method for supplying power to the in-car device, for example, as shown in Patent Document 1, there is a method in which an induction wire is stretched so as to be substantially parallel to the moving direction and current is taken out by the power receiving coil. A method is shown in which a guide wire is laid one by one at a symmetrical position around the center of the car, one power receiving unit is provided on each side, and a substantially constant current is taken out even if the car is shifted left and right. . Patent Document 2 discloses a method for supplying power to a slide door from two power transmission units provided on an upper frame of an elevator car.

しかしながら、特許文献１では前後のずれには対応できないため、取り出せる電流の低下、すなわち効率の低下が懸念される。また、２本の誘導線を左右対称の位置に長い距離、精度よく取り付ける必要があるため据付性が低下し、かごの周辺にはおもりや位置検出装置、安全装置等の周辺物があるため、エレベータの占有面積が増えるおそれがある。特許文献２ではかご上のドア側の面に２つの送電部を設けているが、位置ずれが発生する。   However, since Patent Document 1 cannot cope with the front-back displacement, there is a concern that the current that can be taken out decreases, that is, the efficiency decreases. In addition, since it is necessary to attach the two guide wires to a symmetrical position at a long distance and with high accuracy, the installation property is lowered, and there are peripherals such as a weight, a position detection device, and a safety device around the car. There is a risk that the occupied area of the will increase. In Patent Document 2, two power transmission units are provided on the door side surface of the car, but a positional shift occurs.

以上のことから、非接触給電を行う移動体システムにおいて、据付性がよく省スペース化が図れ、前後左右すべての位置ずれの影響を低減する非接触給電装置を提供することが本発明の目的の一つである。   In view of the above, it is an object of the present invention to provide a non-contact power feeding device that can be installed in a mobile system that performs non-contact power feeding, has good installation characteristics, and can reduce the influence of all the positional deviations in the front, rear, left, and right. One.

上記の課題の少なくとも一を解決するために、本発明の一態様では、移動体と、前記移動体の周囲に設けられた第１の送電装置及び第２の送電装置と、前記第１の送電装置から非接触で給電される前記移動体の第１の面に設けられた第１の受電装置と、前記第２の送電装置から非接触で給電される前記第１の面に設けられた第２の受電装置を備え前記第１の送電装置と前記第１の受電装置の結合率と、前記第２の送電装置から前記第２の受電装置の結合率が前記移動体の位置ずれにより相反し、かつ前記第１の送電装置及び前記第２の送電装置により給電を行う。   In order to solve at least one of the above problems, according to one embodiment of the present invention, a mobile body, a first power transmission device and a second power transmission device provided around the mobile body, and the first power transmission A first power receiving device provided on the first surface of the moving body fed in a contactless manner from the device, and a first power receiving device provided on the first surface fed in a contactless manner from the second power transmission device. 2, the coupling rate between the first power transmission device and the first power reception device, and the coupling rate between the second power transmission device and the second power reception device are contradictory due to the displacement of the moving body. In addition, power is supplied by the first power transmission device and the second power transmission device.

本発明の一態様によると、給電効率の低下を低減することができる。   According to one embodiment of the present invention, reduction in power supply efficiency can be reduced.

In each drawing and each embodiment, the same or similar components are denoted by the same reference numerals, and description thereof is omitted.

The mobile body system includes a mobile body 4, guide rails 4 a and 4 b, a control unit 5, power transmission devices 21 and 22, and power reception devices 31 and 32.

移動体４はエレベータの乗りかごで、図１においては紙面に向かって垂直な方向に移動する。また、移動体４は、図２においては、ｙ軸の正負方向に移動する。ガイドレール４ａ、４ｂはエレベータの移動方向に沿って設置される。制御部５は、エレベータの運行、乗りかご４の停止や速度、図示していないが周辺機器等への電力供給等を制御する。蓄電装置７は受電した電力を蓄電する鉛蓄電池やリチウムイオン電池、キャパシタ等である。送電装置２１、２２は非接触給電を行い、昇降路内に設置される。受電装置３１、３２は非接触給電を行い、受電装置３１および３２は乗りかご４のある一面に取り付けし、相反する向きに設置される。送電回路１０は、送電装置２１および２２の少なくとも一方に電力を供給する。   The moving body 4 is an elevator car and moves in a direction perpendicular to the paper surface in FIG. In addition, the moving body 4 moves in the positive and negative directions of the y-axis in FIG. The guide rails 4a and 4b are installed along the moving direction of the elevator. The control unit 5 controls the operation of the elevator, the stop and speed of the car 4, the power supply to peripheral devices (not shown), and the like. The power storage device 7 is a lead storage battery, a lithium ion battery, a capacitor, or the like that stores the received power. The power transmission devices 21 and 22 perform non-contact power feeding and are installed in the hoistway. The power receiving devices 31 and 32 perform non-contact power feeding, and the power receiving devices 31 and 32 are attached to one surface of the car 4 and installed in opposite directions. The power transmission circuit 10 supplies power to at least one of the power transmission devices 21 and 22.

Gz1はZ方向の送電装置２１と受電装置３１のギャップで、Gz2はZ方向の送電装置２２と受電装置３２のギャップである。GxはX方向の送電装置２１および２２と受電装置３１および３２のギャップである。 制御部５は送電装置２１および２２が設置された給電階へ到着したことを位置検出装置４２で取得した情報から判断する。蓄電装置７の電池残量を確認し、充電が必要であれば送電回路をオンし、送電装置２１および２２を介してそれぞれ受電装置３１および３２で受電する。受電回路６は、受電装置３１及び３２の少なくとも一方から電力を受け、受電した電力を蓄電装置７に充電する。   Gz1 is a gap between the power transmission device 21 and the power reception device 31 in the Z direction, and Gz2 is a gap between the power transmission device 22 and the power reception device 32 in the Z direction. Gx is a gap between the power transmission devices 21 and 22 and the power reception devices 31 and 32 in the X direction.

The remaining battery level of the power storage device 7 is confirmed. If charging is necessary, the power transmission circuit is turned on, and the power reception devices 31 and 32 receive power via the power transmission devices 21 and 22, respectively. The power receiving circuit 6 receives power from at least one of the power receiving devices 31 and 32 and charges the power storage device 7 with the received power.

The rope 44 suspends the car 4 to raise and lower the car 4.

図３に送電装置２１の詳細を示す。図３（ａ）はＸＺ面、図３（ｂ）はＸＹ面から見た図である。２１０はリッツ線等の電線を巻いた送電コイルで、図示していないがコイル両端は送電回路に接続される。２１２は送電コイル２１０で発生した磁束の磁路を形成する磁性体のフェライトである。２１３は送電コイル２１０やフェライト２１２の支持、磁界をシールドするアルミ等の支持体である。２１４は非磁性体や非金属から成るコイル支持体である。   FIG. 3 shows details of the power transmission device 21. 3A is a view as seen from the XZ plane, and FIG. 3B is a view as seen from the XY plane. Reference numeral 210 denotes a power transmission coil in which an electric wire such as a litz wire is wound. Although not shown, both ends of the coil are connected to a power transmission circuit. Reference numeral 212 denotes a magnetic ferrite that forms a magnetic path of magnetic flux generated in the power transmission coil 210. Reference numeral 213 denotes a support such as aluminum that supports the power transmission coil 210 and the ferrite 212 and shields the magnetic field. Reference numeral 214 denotes a coil support made of a nonmagnetic material or a nonmetal.

図４に受電装置３１の詳細を示す。図４（ａ）はＸＺ面、図４（ｂ）は図４（ａ）のA-A’面の断面をＸＹ面から見た図である。３１０は送電コイル２１０と同様の受電コイルであり、送電コイル２１０で発生した磁束が鎖交することで電力を得る。３１２は磁性体のフェライトである。３１３はコイルの支持や磁界をシールドするアルミ等の支持体である。   FIG. 4 shows details of the power receiving device 31. 4A is a view of the XZ plane, and FIG. 4B is a view of the cross section of the A-A ′ plane of FIG. 4A viewed from the XY plane. Reference numeral 310 denotes a power receiving coil similar to the power transmitting coil 210, and obtains electric power by interlinking the magnetic flux generated in the power transmitting coil 210. Reference numeral 312 denotes a magnetic ferrite. Reference numeral 313 denotes a support such as aluminum that supports the coil and shields the magnetic field.

図５は乗りかご４が所望の位置にある際の送電装置２１および２２と受電装置３１および３２の詳細を示した構成図である。Gzlは送電コイル２１０と受電コル３１０のZ方向の空隙である。Gzrは送電コイル２１０と受電コル３１０のZ方向の空隙である。Gx１は送電コイル２１０とフェライト３１２の最短のX方向の空隙である。Gx２は送電コイル２２０とフェライト３２２の最短のX方向の空隙であり、Gx1とは反比例の関係にある。   FIG. 5 is a configuration diagram showing details of the power transmission devices 21 and 22 and the power reception devices 31 and 32 when the car 4 is in a desired position. Gzl is a gap in the Z direction between the power transmission coil 210 and the power receiving cor 310. Gzr is a gap in the Z direction between the power transmission coil 210 and the power receiving cor 310. Gx1 is the shortest gap in the X direction between the power transmission coil 210 and the ferrite 312. Gx2 is the shortest gap in the X direction between the power transmission coil 220 and the ferrite 322, and is in an inversely proportional relationship with Gx1.

図６は乗りかご４が所望の給電位置から乗りかご４がＸ方向に位置ずれした際の構成図である。図７は位置ずれXを横軸とした送電装置と受電装置の結合率である。空隙Gzlと空隙Gzrはほぼ等しく、Gx1>Gx2の状態である。X=0で位置ずれのない場合を基準とすると、位置ずれXが大きくなったGx1>Gx2の条件では、送電装置２１と受電装置３１は離れるため、結合が小さくなる。一方、送電装置２２と受電装置３２は近づき結合が大きくなる。位置ずれXが小さくなったGx1<Gx2の条件ではそれぞれ前述とは逆の特性となる。このようにかごのある一面に受電装置３１の取り付け向きに対して受電装置３２を反対向きに取り付け、送電装置２１と送電装置２２をそれぞれ取り付けることでずれに対して相反する特性を得ることができる。   FIG. 6 is a configuration diagram when the car 4 is displaced in the X direction from a desired power feeding position. FIG. 7 shows the coupling rate between the power transmitting device and the power receiving device with the positional deviation X as the horizontal axis. The gap Gzl and the gap Gzr are almost equal, and Gx1> Gx2. Based on the case where X = 0 and no positional deviation is used as a reference, under the condition of Gx1> Gx2 where the positional deviation X is large, the power transmitting device 21 and the power receiving device 31 are separated, so that the coupling becomes small. On the other hand, the power transmission device 22 and the power reception device 32 approach each other and the coupling increases. Under the condition of Gx1 <Gx2 where the positional deviation X is small, the characteristics are opposite to those described above. Thus, by attaching the power receiving device 32 in the opposite direction with respect to the mounting direction of the power receiving device 31 on one surface of the car and attaching the power transmitting device 21 and the power transmitting device 22 respectively, it is possible to obtain characteristics that conflict with the deviation. .

図８は乗りかご４が所望の給電位置から-Ｚ方向に位置ずれした際の構成図で図９は位置ずれZを横軸とした各送電装置と受電装置の結合率である。空隙Gx１と空隙Gx２はほぼ等しく、Gzl>Gzrの状態である。比較対象のZ方向をコイル軸とする２つの平面コイルを対向させた給電装置では結合率の変動は-10mmから10mmで約30%変動する。一方で本実施例のトランスは送電コイルを２つの受電コイルで挟み込む構造としているため、Z方向の位置ずれに対して送電装置２１または２２の送電コイル２１０または２２０が受電装置３１または３２の受電コイル３１０または３２０のどちらか一方に近づくため、結合率の変動は約4%と小さい。   FIG. 8 is a configuration diagram when the car 4 is displaced in the −Z direction from a desired power feeding position, and FIG. 9 is a coupling rate of each power transmitting device and power receiving device with the positional displacement Z as a horizontal axis. The gap Gx1 and the gap Gx2 are almost equal, and Gzl> Gzr. In a power feeding device in which two planar coils having a coil axis in the Z direction as a comparison target are opposed to each other, the variation of the coupling rate varies by about 30% from -10 mm to 10 mm. On the other hand, since the transformer of the present embodiment has a structure in which the power transmission coil is sandwiched between two power reception coils, the power transmission coil 210 or 220 of the power transmission device 21 or 22 is replaced with the power reception coil of the power reception device 31 or 32 with respect to the misalignment in the Z direction. Since it approaches either one of 310 or 320, the variation of the coupling rate is as small as about 4%.

以上の構成により、２つの給電装置をかごの一面に集約しつつ、位置ずれに対して結合率の変動が小さい非接触給電装置を用いた移動体システムを提供することができる。   With the above configuration, it is possible to provide a mobile system using a non-contact power feeding device in which the fluctuation of the coupling rate is small with respect to the positional deviation while consolidating the two power feeding devices on one surface of the car.

尚、かごのある一面に据え付けたがこれに限らない。例えば、図１０のようにある一面からオフセットさせた位置に配置してもよい。これにより、様々な昇降路の形状にも適用することができる。   Although it is installed on one side of the car, it is not limited to this. For example, you may arrange | position in the position offset from a certain surface like FIG. Thereby, it is applicable also to the shape of various hoistways.

尚、送電装置２１、２２を昇降路に取り付けたがこれに限らない。例えば図１１に示すように送電装置の支持体２１３および２２３をガイドレール４ｂに取り付けることで送電装置からの配線が集約できるため省スペース化が図れ、不要な配線を削減でき据付性が向上する。また、送電装置２１および２２を受電用途として、受電装置３１および３２を送電用途としてもよいし、設置スペースや周囲構造を鑑みて組み合わせてもよい。   In addition, although the power transmission apparatuses 21 and 22 were attached to the hoistway, it is not restricted to this. For example, as shown in FIG. 11, by attaching the support members 213 and 223 of the power transmission device to the guide rail 4b, wiring from the power transmission device can be collected, so that space saving can be achieved, unnecessary wiring can be reduced, and installation efficiency is improved. Further, the power transmission devices 21 and 22 may be used for power reception, and the power reception devices 31 and 32 may be used for power transmission, or may be combined in consideration of the installation space and the surrounding structure.

図１２は、上述の実施例における変形例の一つである非接触給電装置を用いたエレベータを示す概略の構成図である。前記実施例では送電装置２１、２２と受電装置３１，３２を同じ高さ（Y軸の位置）に取り付けたが本実施例では送電装置２１および受電装置３１と、送電装置２２および受電装置３２の取り付けの高さが異なる。Z軸を中心とした乗りかご４の回転軸に対して点対称となる位置に取り付けるのが望ましい。Z軸を中心とした乗りかご４の回転による位置ずれが発生した場合、送電装置２１が受電装置３１に近づくと、送電装置２２が受電装置３２に近づき相反する特性を得ることができ位置ずれによる結合率の変動を相殺することができる。   FIG. 12 is a schematic configuration diagram illustrating an elevator using a non-contact power feeding device which is one of the modifications in the above-described embodiment. In the above-described embodiment, the power transmission devices 21 and 22 and the power reception devices 31 and 32 are attached at the same height (Y-axis position), but in this embodiment, the power transmission device 21 and the power reception device 31, the power transmission device 22 and the power reception device 32. Mounting height is different. It is desirable to attach to a position that is point-symmetric with respect to the rotation axis of the car 4 around the Z axis. When a displacement occurs due to rotation of the car 4 around the Z axis, when the power transmission device 21 approaches the power reception device 31, the power transmission device 22 approaches the power reception device 32 and can obtain a contradictory characteristic. Variations in the coupling rate can be offset.

以上の構成により、かごの一面に据え付けるため省スペース化が図れ、Z軸を中心とした乗りかご４の回転による位置ずれに対し、結合率の変動が小さくなり効率向上が図れる。   With the above configuration, the space can be saved because it is installed on one surface of the car, and the fluctuation of the coupling rate is reduced with respect to the positional deviation caused by the rotation of the car 4 around the Z axis, and the efficiency can be improved.

図１３は、上述の実施例における変形例の一つである非接触給電装置を用いたエレベータを示す概略の構成図である。   FIG. 13 is a schematic configuration diagram showing an elevator using a non-contact power feeding device which is one of the modifications in the above-described embodiment.

前記実施例では２つの送電装置および受電装置によって給電を行った。本実施例では３つ以上の送電装置および受電装置によって給電を行う。送電装置２１をY方向に平行移動させた位置に送電装置２３を、送電装置２２をY方向に平行移動させた位置に送電装置２４を配置する。また受電装置３１をY方向に平行移動させた位置に受電装置３３を、受電装置３２をY方向に平行移動させた位置に受電装置３４を配置する。   In the embodiment, power is supplied by two power transmission devices and a power reception device. In this embodiment, power is supplied by three or more power transmission devices and power reception devices. The power transmission device 23 is disposed at a position where the power transmission device 21 is translated in the Y direction, and the power transmission device 24 is disposed at a position where the power transmission device 22 is translated in the Y direction. Further, the power receiving device 33 is arranged at a position where the power receiving device 31 is translated in the Y direction, and the power receiving device 34 is arranged at a position where the power receiving device 32 is translated in the Y direction.

以上の構成により、かごの一面に据え付けるため省スペース化および乗りかご４位置ずれに対し、結合率の変動が小さくなり効率向上が図れ、大電力を伝送することが可能となる。   With the above-described configuration, since it is installed on one surface of the car, the variation in the coupling rate is reduced and the efficiency is improved with respect to the space saving and the car 4 position shift, and it is possible to transmit a large amount of power.

尚、かごの一面の四隅に受電装置を配置したがこれに限らない。例えば、図１４のように送電装置２１、２２を昇降路に、送電装置２３、２４をガイドレール４ｂに取り付けてもよい。また、送電装置、受電装置をそれぞれ同じ高さ（Y軸の位置）に設置することにより、据付性、保守性が向上する。前述のようにそれぞれの設置位置を変えれば回転によるずれにも対応できる。さらに大電力を送電しない場合、１つ以上の送電装置をオフにするなどして省エネを図ってもよい。   In addition, although the power receiving apparatus was arrange | positioned in the four corners of one surface of a cage | basket | car, it is not restricted to this. For example, as shown in FIG. 14, the power transmission devices 21 and 22 may be attached to the hoistway and the power transmission devices 23 and 24 may be attached to the guide rail 4b. Further, by installing the power transmitting device and the power receiving device at the same height (position of the Y axis), the installability and maintainability are improved. As described above, if the respective installation positions are changed, it is possible to cope with a shift due to rotation. Further, when large power is not transmitted, energy may be saved by turning off one or more power transmission devices.

尚、１つの送電回路１０が各送電装置への電力供給を行うようにしたが、これに限らない。送電回路１０内には各送電装置分のインバータが内蔵されていてもよいし、各送電装置ごとに送電回路を持つ分離した構造としてもよい。   Although one power transmission circuit 10 supplies power to each power transmission device, the present invention is not limited to this. The power transmission circuit 10 may include an inverter for each power transmission device, or may have a separate structure having a power transmission circuit for each power transmission device.

つまり上述の実施例とすることで、前後左右すべての位置ずれに対し、２つの給電ユニットで結合係数の変動を抑え効率の低下を低減することが可能となる。上述の実施例により移動体の一面に取り付けることができるため省スペース化及び据付性の向上が図れる。   In other words, with the above-described embodiment, it is possible to suppress a decrease in efficiency by suppressing fluctuations in the coupling coefficient with two power supply units with respect to all the positional deviations in the front, rear, left, and right directions. Since it can be attached to one surface of the moving body according to the above-described embodiment, it is possible to save space and improve installation.
