請求項２の発明での追加の課題は、制御線を制御盤の制御基板等簡単に導けるようにすることにある。
請求項３の発明での追加の課題は、コンパクトで放熱性と美観に優れた制御盤をスタッカークレーンに搭載し、特に制御盤背面の冷却部が目立たずかつ触れられるおそれがないように配置することにある。 An object of the present invention is to provide a control panel that is compact and excellent in heat dissipation and aesthetics.
An additional problem in the invention of claim 2 is that the control line can be easily led to the control board of the control panel.
An additional problem in the invention of claim 3 is that a compact control panel with excellent heat dissipation and aesthetics is mounted on a stacker crane, and in particular, the cooling part on the back of the control panel is not conspicuous and is not touched. There is.

この発明は、電装機器を取り付けた取付板の４周をフレームで囲み、前面側に扉を設けた制御盤において、
前記取付板の背面側が周囲に露出し、かつ前記電装機器の冷却部が取付板の背面から突き出すようにしたことを特徴とする。 The present invention is a control panel in which four rounds of a mounting plate to which electrical equipment is mounted is surrounded by a frame and a door is provided on the front side.
The back side of the mounting plate is exposed to the surroundings, and the cooling part of the electrical equipment protrudes from the back side of the mounting plate.

好ましくは、取付板背面側に制御線の配線ダクトを設ける。   Preferably, a wiring duct for the control line is provided on the back side of the mounting plate.

またこの発明は、電装機器を取り付けた取付板の４周をフレームで囲み、前面側に扉を設け、取付板の背面側を周囲に露出させ、かつ前記電装機器の冷却部を取付板の背面から突き出させた制御盤を、その背面側がスタッカークレーンの駆動部材を向くように配置した、スタッカークレーンにある。   The present invention also includes a frame surrounding the mounting plate on which the electrical equipment is mounted, a door provided on the front side, the back side of the mounting plate exposed to the surroundings, and the cooling part of the electrical equipment connected to the back side of the mounting plate. There is a stacker crane in which the control panel protruded from is arranged so that the back side faces the drive member of the stacker crane.

この発明では、電装機器の放熱は取付板の背面側に突き出したフィンやファンなどで行われ、取付板の背面側が開放されているので、冷却が容易でしかも背面板が不要な分だけ制御盤を小形化できる。取付板の前面は扉で覆われ、側面はフレームで囲まれているので、前面や側面はきれいに仕上げることができる。そこで背面側が目立たない位置にこの発明の制御盤を設置すると、省スペースで冷却効率が良く、しかも美観に優れた制御盤となる。   In this invention, the heat from the electrical equipment is radiated by fins or fans protruding to the back side of the mounting plate, and the back side of the mounting plate is open, so that the control panel can be easily cooled and does not require the back plate. Can be miniaturized. Since the front face of the mounting plate is covered with a door and the side face is surrounded by a frame, the front face and side face can be finished cleanly. Therefore, if the control panel according to the present invention is installed at a position where the back side is not conspicuous, the control panel is space-saving, has good cooling efficiency, and is excellent in aesthetics.

この発明では、制御盤の背面側が開放されているので、制御線の配線ダクトを設けることができ、この結果、制御線を動力線とは別に配線ダクトに収容して、制御基板側へ容易に導くことができる。   In the present invention, since the back side of the control panel is open, it is possible to provide a wiring duct for the control line. As a result, the control line is accommodated in the wiring duct separately from the power line and can be easily moved to the control board side. Can lead.

この発明の制御盤を背面側がスタッカークレーンのマストや走行モータ、昇降モータ、ドラムなどの駆動部材を向くように配置すると、制御盤の背面側が目立たないので、小形、省スペースで電装機器の冷却効率に優れ、また冷却部に触れられることが無く、しかも美観に優れた制御盤になる。   If the control panel of this invention is arranged so that the back side faces the mast of the stacker crane, the driving motor such as the traveling motor, the lifting motor, and the drum, the back side of the control panel is inconspicuous, so the cooling efficiency of the electrical equipment is small and space saving The control panel is excellent in aesthetics and is not touched by the cooling part.

以下に本発明を実施するための最適実施例を示す。   In the following, an optimum embodiment for carrying out the present invention will be shown.

図１〜図６に、実施例の制御盤２と、これを搭載したスタッカークレーン５０，５１を示す。各図において、４は制御盤２の扉、６はフレーム、８は取付板で、取付板８の４周をフレーム６が囲み、制御盤２の前面側を扉４が開閉自在に覆い、背面側は取付板８が露出している。９は制御基板ボックスで、ここでは取付板８と別体にしたが、取付板８と一体にしてもよい。１０は取付板８の前面、１１は背面で、前面１０は扉４により覆われ、背面１１はほぼ全面が露出している。１２は吊りボルト、１４は足で制御盤２を支持する。取付板８の前面１０側には、走行モータや昇降モータのインバータ１６，１７、電力回生コンバータ１８、ブレーカ１９、マグネットスイッチ２０などの電装機器が設けられ、制御基板ボックス９内の図示しない制御基板からリレー基板２２を制御し、インバータ１６，１７，コンバータ１８，ブレーカ１９，マグネットスイッチ２０などの電装機器を制御する。   1 to 6 show a control panel 2 of the embodiment and stacker cranes 50 and 51 on which the control panel 2 is mounted. In each figure, 4 is a door of the control panel 2, 6 is a frame, 8 is a mounting plate, the frame 6 surrounds the circumference of the mounting plate 8, and the door 4 covers the front side of the control panel 2 so that it can be opened and closed. On the side, the mounting plate 8 is exposed. Reference numeral 9 denotes a control board box, which is separated from the mounting plate 8 here, but may be integrated with the mounting plate 8. 10 is a front surface of the mounting plate 8, 11 is a back surface, the front surface 10 is covered by the door 4, and the back surface 11 is almost entirely exposed. Reference numeral 12 is a suspension bolt, and 14 is a foot that supports the control panel 2. On the front face 10 side of the mounting plate 8, electrical equipment such as inverters 16 and 17 for travel motors and lift motors, a power regeneration converter 18, a breaker 19, and a magnet switch 20 are provided. The relay board 22 is controlled to control electrical equipment such as the inverters 16 and 17, the converter 18, the breaker 19, and the magnet switch 20.

取付板８の背面１１側には、インバータ１６，１７，コンバータ１８などの放熱フィン２４〜２６が突き出し、また放熱フィン２６と一体にファン２８が設けてある。さらに背面１１側の下部に棒３０を設けて、制御盤２を出入りするケーブル類の長さを調整するために、巻いたケーブルを固定する。棒３０に代えて板やフックなどの係止部材でもよい。背面１１側の上部にはフレーム６の天板３２があり、下部には底板３３がある。なお取付板８の背面側で天板３２を切り欠いてもよく、また底板３３には部分的に切り欠き３７が設けてある。背面１１側には上下に延びる制御線ダクト３４と、制御線ダクト３４の上端側から取付板８の前面側へつながる制御線入口孔３６が設けてある。このようにして棒３０に固定したケーブルのうち、制御ケーブルをダクト３４から制御線入口孔３６を介して取付板８の前面側へ導き、制御基板ボックス９へと接続する。棒３０に固定した動力ケーブルは、切り欠き３７からフレーム６の底部に設けた動力線入口孔３８を介して、マグネットスイッチ２０やブレーカ１９等と接続する。   On the back surface 11 side of the mounting plate 8, heat radiation fins 24 to 26 such as the inverters 16, 17 and the converter 18 protrude, and a fan 28 is provided integrally with the heat radiation fin 26. Furthermore, a rod 30 is provided at the lower part on the back surface 11 side, and the wound cable is fixed in order to adjust the length of the cables entering and leaving the control panel 2. Instead of the rod 30, a locking member such as a plate or a hook may be used. There is a top plate 32 of the frame 6 at the upper part on the rear surface 11 side, and a bottom plate 33 at the lower part. The top plate 32 may be cut out on the back side of the mounting plate 8, and the notch 37 is partially provided in the bottom plate 33. On the rear surface 11 side, a control line duct 34 extending vertically and a control line inlet hole 36 connected from the upper end side of the control line duct 34 to the front surface side of the mounting plate 8 are provided. Of the cables fixed to the rod 30 in this way, the control cable is guided from the duct 34 to the front side of the mounting plate 8 via the control line inlet hole 36 and connected to the control board box 9. The power cable fixed to the rod 30 is connected to the magnet switch 20, the breaker 19, and the like through the notch 37 and the power line inlet hole 38 provided at the bottom of the frame 6.

図４，図５に、制御盤２を搭載したスタッカークレーン５０，５１を示す。図４に示すように、スタッカークレーン５０は走行レール５２に沿って走行し、５４は台車で、５６は駆動車輪、５８は従動車輪である。６０，６２はマストで、１本マストなどでもよく、６４は昇降台、６６はスライドフォークで、他の移載手段でもよい。駆動車輪５６側に走行モータ６８と昇降モータ７０とを集約配置し、昇降モータ７０でドラム７２を回転させて、昇降台６４を昇降させるための吊持材７４を巻き取り繰り出す。走行モータ６８側に取付板８の背面１１側が向き合うように制御盤２を配置する。この結果、制御盤２の背面１１は走行モータ６８などの側に配置され、背面１１側を露出させても放熱フィン等が目立たない。そして取付板８に取り付けたインバータなどの電装機器からの発熱は、放熱フィン２４〜２６やファン２８などにより冷却され、これらを背面板と取付板８との間の狭いスペースに収容する場合に比べて、冷却が容易になる。さらに背面板が不要な分だけ制御盤２を小型化できる。   4 and 5 show stacker cranes 50 and 51 on which the control panel 2 is mounted. As shown in FIG. 4, the stacker crane 50 travels along a traveling rail 52, 54 is a carriage, 56 is a drive wheel, and 58 is a driven wheel. Reference numerals 60 and 62 denote masts, which may be a single mast, 64 is a lifting platform, 66 is a slide fork, and may be another transfer means. The traveling motor 68 and the lifting motor 70 are centrally arranged on the drive wheel 56 side, the drum 72 is rotated by the lifting motor 70, and the suspension material 74 for lifting the lifting platform 64 is taken up and delivered. The control panel 2 is arranged so that the back surface 11 side of the mounting plate 8 faces the traveling motor 68 side. As a result, the back surface 11 of the control panel 2 is disposed on the side of the traveling motor 68 and the like, and even if the back surface 11 side is exposed, the heat radiation fins and the like are not conspicuous. And the heat generated from the electrical equipment such as an inverter attached to the mounting plate 8 is cooled by the radiation fins 24 to 26 and the fan 28, and compared with the case where these are accommodated in a narrow space between the back plate and the mounting plate 8. Cooling becomes easier. Furthermore, the control panel 2 can be reduced in size by the amount that the back plate is unnecessary.

図４では走行モータ６８と昇降モータ７０を台車５４の一方に集約したが、これらを台車５４の前後に分散させてもよい。この場合、制御盤２を走行モータ６８用と昇降モータ７０用とに分割して台車の前後に配置するか、制御盤２を台車５４の前後一方に配置して、他方との間をケーブルで接続することが好ましい。   In FIG. 4, the traveling motor 68 and the lifting motor 70 are integrated into one of the carriages 54, but these may be dispersed before and after the carriage 54. In this case, the control panel 2 is divided into the traveling motor 68 and the lifting motor 70 and arranged in front of and behind the carriage, or the control panel 2 is arranged in one of the front and rear of the carriage 54 and the other is connected with a cable. It is preferable to connect.

図５は変形例のスタッカークレーン５１を示し、図４と同じ記号は同じものを表す。スタッカークレーン５１では制御盤２の扉を台車５４の前部側面に配置し、取付板８の背面１１側を走行モータ６８を向くように取り付ける。背面１１は走行モータ６８などの側にあるので、背面側の放熱フィン等が目立たず、背面１１側に背面板がないので、背面１１側での冷却が容易で、制御盤２をコンパクトにできる点は、図４の実施例と同様である。   FIG. 5 shows a modified stacker crane 51, and the same symbols as those in FIG. In the stacker crane 51, the door of the control panel 2 is arranged on the front side surface of the carriage 54, and the rear surface 11 side of the mounting plate 8 is attached so as to face the traveling motor 68. Since the back surface 11 is on the side of the traveling motor 68 and the like, the heat radiation fins on the back side are not conspicuous, and there is no back plate on the back surface 11 side, so cooling on the back surface 11 side is easy and the control panel 2 can be made compact. The point is the same as the embodiment of FIG.

図６に、制御盤２とスタッカークレーンの各部との接続関係を示す。８０は動力ケーブル、８２は制御ケーブルで、動力ケーブル８０は３相交流などの電源と、走行モータや昇降モータ並びに昇降台のスライドフォークなどに接続し、動力線入口孔３８から取付板８の前面下部へと引き出され、例えば同じ動力線入口孔３８から各モータやスライドフォークへ配線される。制御ケーブル８２は、通信インターフェースなどを介して、スタッカークレーンの地上制御盤と接続され、他にセンサ類やスライドフォークの制御信号並びに制御電源線が含まれ、制御線入口孔３６を介して取付板８の上部から制御基板ボックス９へ接続される。以上のように、動力ケーブル８０と制御ケーブル８２とで配線の引き回しを変えるので配線が容易になる。   FIG. 6 shows the connection relationship between the control panel 2 and each part of the stacker crane. 80 is a power cable, 82 is a control cable, and the power cable 80 is connected to a power source such as a three-phase alternating current, a traveling motor, a lifting motor, a slide fork of a lifting platform, and the like. It is pulled out to the lower part and wired from the same power line inlet hole 38 to each motor and slide fork, for example. The control cable 82 is connected to the ground control panel of the stacker crane via a communication interface or the like. In addition, the control cable 82 includes sensors and control signals for the slide fork and the control power supply line. 8 is connected to the control board box 9 from above. As described above, since the wiring of the power cable 80 and the control cable 82 is changed, the wiring becomes easy.

実施例では制御盤２をスタッカークレーンに搭載したが、他の搬送台車に搭載してもよく、あるいは地上固定の制御盤として用いてもよい。さらにフレーム６は取付板４の背面１１側は囲まなくても良い。
In the embodiment, the control panel 2 is mounted on the stacker crane. However, the control panel 2 may be mounted on another transport cart, or may be used as a control panel fixed on the ground. Further, the frame 6 does not have to surround the back surface 11 side of the mounting plate 4.
