Description

バッテリーを電源とする移動体のバッテリーを充電するために専用充電器を搭載する。 その充電器に供給する電源を、電磁誘導を利用して電気的に非接触の方法で、供給する装置、商用電源を電磁誘導用の電源に変換する装置、及び電磁結合器を、結合、分離する装置。A dedicated charger is installed to charge the battery of a mobile unit that uses the battery as a power source. Combines and separates the power supply to be supplied to the charger in an electrically non-contact manner using electromagnetic induction, the device for converting commercial power to the power for electromagnetic induction, and the electromagnetic coupler Device to do.

従来バッテリーを、電源として、電動機を動力とする移動体（工場用無人搬送車及びゴルフカート）のバッテリーは、定期的に充電をしなければならない。殆どのものは充電器を搭載していないため、車体からバッテリーを取り外して、所定の場所にある固定された充電器に接続して充電をしている。A battery of a mobile body (a factory automatic guided vehicle and a golf cart) using a conventional battery as a power source and a motor as a power source must be charged regularly. Most of them do not have a charger, so the battery is removed from the car body and connected to a fixed charger in place to charge.

バッテリーを電源とする移動体において、充電器を搭載してあるものもある。それらは充電する時、所定の場所にある商用電源のコンセントにより電源を供給している。Some mobiles powered by a battery are equipped with a charger. When they are charged, they are powered by a commercial power outlet in place.

バッテリーを電源とする移動体のバッテリーを、充電する方法としてバッテリーを取り外して、所定の場所に設置された、充電器に接続して行う方法は、重量のおおきいバッテリーを取り扱う作業は、労働安全衛生法上において問題があることがある。As a method of charging a mobile battery powered by a battery, remove the battery and connect it to a charger installed in place. There may be legal problems.

バッテリーを電源とする移動体のバッテリーを充電する方法として、充電器を移動体に搭載してその電源の供給の方法として、商用電源からコンセント及びプラグを介して、供給すれば重量物であるバッテリーを取り扱う必要はないが、プラグの接続に人手を必要とする。また環境が悪いとき、たとえば高温多湿の状況下では感電の危険性がある、可燃性ガス等が発生するような状況下では、プラグの接続時に発生するスパークによる火花により、火災が発生する危険性がある。As a method of charging a battery of a moving body that uses a battery as a power source, a battery that is heavy if it is supplied from a commercial power source via an outlet and a plug as a method of supplying a power source by mounting a charger on the moving body. It is not necessary to handle the plug, but it requires manual labor to connect the plug. Also, when the environment is bad, for example, there is a risk of electric shock in hot and humid conditions, and in situations where flammable gas is generated, there is a risk of fire due to sparks generated when the plug is connected. There is.

移動体に電源として搭載したバッテリーを、充電するために搭載した充電器の電源を供給するのを、無人化するため電気的な接続をすると、磨耗等により接続不良が発生して、接続部の過熱及びスパークによる火花の発生により、火災の発生する危険がある。If a battery mounted as a power source for a mobile unit is supplied with electric power for charging the battery charger installed to charge the battery, a connection failure may occur due to wear, etc. Risk of fire due to overheating and sparks from sparks.

バッテリーを電源とする電動移動体のバッテリーを、充電するため専用の充電器を搭載する。このことにより重量のあるバッテリーの扱いが不要となり労働衛生法上の問題がなくなる。A dedicated charger is installed to charge the battery of the electric vehicle that uses the battery as its power source. This eliminates the need for handling heavy batteries and eliminates problems with the Industrial Health Act.

移動体に搭載した充電器に電源を供給する方法として、電磁誘導による方法による時、商用電源を直流電源に整流したのちに、高周波電源に変喚することにより、電磁結合器を小型化できる。電磁結合器を使用することにより、電気的に非接触とすることができるため、感電の危険とスパークにより発生する火花による、火災が発生する危険がなくなる。As a method for supplying power to a charger mounted on a moving body, when using a method based on electromagnetic induction, the electromagnetic coupler can be reduced in size by rectifying the commercial power source to a DC power source and then changing to a high frequency power source. By using an electromagnetic coupler, electrical non-contact can be achieved, eliminating the danger of electric shock and the risk of fire due to sparks generated by sparks.

本発明は移動体に動力源として搭載したバッテリーを、取り外すことなく移動体が停止している間、例えば荷物の積み下ろしをしている場所において、電力の伝送に電磁結合方式を用いて、自動的かつ頻繁に充電することができるため、バッテリーの放電深さが浅くなり、バッテリーの寿命が長くなり経済効果、省資源効果も大となる。電力の伝送に電磁結合式にすることにより、充電基地と移動体の電力伝送のための結合部の、機械的精度に余裕が与えられる、継時変化による磨耗等が発生しても、電気的に補償できるため充電には支障をきたさない、電気的接続方式は継時変化による磨耗により過熱、スパークによる火花発生により、火災等の危険性がある。無人化により人件費の削減はもとより、労働安全衛生法上の問題も解決することができる。The present invention automatically uses an electromagnetic coupling method for power transmission while the mobile unit is stopped without removing the battery mounted as a power source on the mobile unit, for example, when loading or unloading. In addition, since the battery can be charged frequently, the discharge depth of the battery becomes shallow, the life of the battery becomes long, and the economic effect and the resource saving effect become large. By using electromagnetic coupling for power transmission, there is room for mechanical accuracy in the joints for power transmission between the charging base and mobile unit. The electrical connection method has a risk of fire due to overheating due to wear due to changes over time and generation of sparks due to sparks. Unemployment not only reduces labor costs but also solves problems related to occupational safety and health laws.

本発明を添付図面〔図１〕を用いて説明する。図面において１点鎖線の上側を電源供給側として所定の場所に設置する。１点鎖線の下側を受電側として電動機を動力源とする移動体とする。本装置に供給された商用電源２００Ｖは整流、平滑され高周波発振器に供給され２５ＫＨｚの高周波電流を、出力する。高周波出力は、絶縁と変圧のため変圧器に供給される。変圧器の出力は電磁結合器に供給されて磁気エネルギーに変換される。制御回路は定電圧、定電流特性の出力制御及び各種保護機能を制御する。１点鎖線の上側の電磁結合器から出力された磁気エネルギーは、１点鎖線下側の電磁結合器、に送られる、上下（図面上）の磁気結合器は完全に結合するように、機械的に工夫する。受電側（図面において下側）の磁気結合器の出力は高周波の交流電圧であるので、整流回路で整流する。この直流電源を使用して、バッテリーを充電するのに必要な、電圧及び電流にするため定電圧、定電流回路を介して、バッテリーに供給して所定の特性で充電を行う。以上商用電源を利用して、電気的に非接触な方法で分離してある物体に電力を供給することができることになる。このことは電動機を動力とする移動体に搭載したバッテリーを、自動的に電気的非接触な方法で安全に充電することができることになる。The present invention will be described with reference to the accompanying drawings (FIG. 1). In the drawing, the upper side of the alternate long and short dash line is installed at a predetermined place with the power supply side. Let the lower side of a dashed-dotted line be a power receiving side, and let it be a moving body using an electric motor as a power source. The commercial power supply 200V supplied to this apparatus is rectified and smoothed, supplied to a high frequency oscillator, and outputs a high frequency current of 25 KHz. The high frequency output is supplied to the transformer for insulation and transformation. The output of the transformer is supplied to an electromagnetic coupler and converted into magnetic energy. The control circuit controls constant voltage and constant current output control and various protection functions. The magnetic energy output from the electromagnetic coupler on the upper side of the one-dot chain line is sent to the electromagnetic coupler on the lower side of the one-dot chain line, so that the upper and lower (on the drawing) magnetic couplers are completely coupled. Devise to. Since the output of the magnetic coupler on the power receiving side (the lower side in the drawing) is a high-frequency AC voltage, it is rectified by a rectifier circuit. Using this direct current power source, the battery is supplied to the battery via a constant voltage and constant current circuit to obtain the voltage and current necessary for charging the battery, and charging is performed with predetermined characteristics. As described above, electric power can be supplied to an object separated by a non-contact method using a commercial power source. This means that a battery mounted on a moving body powered by an electric motor can be safely charged automatically by an electrically non-contact method.

本発明の実施例を〔図２〕を用いて説明する、車体に取り付けてある、２個のモーターはそれぞれ単独に回転数を制御して、直線及び曲線走行する装置である、車体の走行、停止の指令は、床面に貼り付けた磁気テープの情報を、磁気センサーで検出して所定の指示範囲を、走行する移動体である。また移動体は側面に電磁結合器を取り付けてある、搭載しているバッテリーを充電する電力を、固定された電力供給装置の磁気結合器から、電気的に非接触で受電することができる。一方電力供給側の固定装置は、電源供給側電磁結合器取り付け板は、支点を中心とした円弧運動をする、取り付けられた電磁結合器には、商用電源を電源とするコンバーターにより周波数変換した高周波電流を供給している。移動体は磁気テープの情報により、物品の積み下ろしの場所で停止するようにコースを設定しておく、その停止場所で充電するように、固定装置側と移動体側の電磁結合器を接触するように、機構的に接定する、機構部は、移動体の停止位置が多少ずれても、強制的に電磁結合器が確実に接触するようにしている、荷役が終了すれば発進する、そしてまた次の荷役場所で同様に充電する、走行中に消費した電荷を、停止して荷役中に補充する、そのことはバッテリーの放電深さが浅くして、バッテリーの寿命を長くする。従来の電動機を動力源とする、移動体のバッテリーを取り外して充電する、と言う重労働作業がなくなり、また移動体の稼働率が上昇する。The embodiment of the present invention will be described with reference to FIG. 2. The two motors attached to the vehicle body are devices that run on a straight line and a curve, respectively, by controlling the number of revolutions independently. The stop command is a moving body that travels in a predetermined designated range by detecting information on the magnetic tape affixed to the floor surface with a magnetic sensor. In addition, the mobile body can receive electric power for charging the battery on which the electromagnetic coupler is mounted on the side surface from the magnetic coupler of the fixed power supply device in an electrically non-contact manner. On the other hand, the power supply side fixing device has a power supply side electromagnetic coupler mounting plate that performs a circular arc motion around a fulcrum. The attached electromagnetic coupler has a high frequency that is frequency-converted by a converter that uses a commercial power supply as a power source. Supplying current. The moving body sets the course to stop at the place where the article is loaded and unloaded according to the information on the magnetic tape, so that the fixed device side and the moving body side electromagnetic coupler come into contact so as to charge at the stopping place. The mechanism is fixed mechanically, even if the stop position of the moving body is slightly deviated, the electromagnetic coupler is forcibly brought into contact with each other. In the same manner, the battery is charged at the loading / unloading place, and the electric charge consumed during driving is stopped and replenished during loading / unloading, which reduces the discharge depth of the battery and prolongs the life of the battery. The laborious work of using a conventional electric motor as a power source and removing and charging the battery of the moving body is eliminated, and the operating rate of the moving body increases.

電動機を動力源とする移動体は、各分野で増えてくるであろう、その電源は当分の間は、バッテリーである。が、しかし充電作業は必ず必要であり 的確に実施しないと、移動体の稼働率を低下させ、バッテリーの寿命を低下させる。本発明の自動充電方式は頻繁に充電するため移動体が稼動中に、一時停止したとき充電できる。そのことは、バッテリーの放電深さを浅くできるため、その寿命が永くなり、省資源効果、経済効果、が良くなる。
設置時の費用は、基本的には電気的に、充電器を二つに分割することと、同じである、と考えればあまり設備費は増加しない。The number of mobiles that use electric motors as a power source will increase in each field, and for the time being, the power source is a battery. However, charging work is absolutely necessary, and if it is not performed properly, the operating rate of the mobile unit will be reduced and the battery life will be reduced. Since the automatic charging method of the present invention is frequently charged, it can be charged when the moving body is temporarily stopped during operation. That is, since the discharge depth of the battery can be reduced, its life is prolonged, and the resource saving effect and the economic effect are improved.
The cost of installation is basically the same as dividing the charger into two parts electrically, so that the equipment cost does not increase much.
