Description

電源収納構造Power supply storage structure
　本発明は、電源収納構造に関するものである。 The present invention relates to a power supply storage structure.
　特許文献１には、車輪を有する電源ユニット（溶接電源部）を筐体の内部方向へスライドさせ、電源ユニットを筐体内に収納するようにした電気機器が開示されている。 Patent Document 1 discloses an electrical device in which a power supply unit (welding power supply section) with wheels slides toward the inside of a housing, allowing the power supply unit to be stored within the housing.
　特許文献１の発明では、筐体内に電源ユニットを収納した状態で、第１のＬ字形状部材と第２のＬ字形状部材を各々に設けられた長穴に沿って鉛直下方向にスライドさせて電源ユニットの天板に当接させた状態で固定して、天板と第１のＬ字形状部材と第２のＬ字形状部材とにより、筐体内部を上下２つの空間に仕切るようにしている。 In the invention of Patent Document 1, with the power supply unit stored inside the housing, the first L-shaped member and the second L-shaped member are slid vertically downward along the long holes provided in each member and fixed in a state where they abut against the top plate of the power supply unit, so that the inside of the housing is divided into two spaces, an upper and lower, by the top plate, the first L-shaped member, and the second L-shaped member.

　ところで、特許文献１の発明では、例えば、電気機器の搬送中に振動が加わった場合でも、電源ユニットの天板に当接させたＬ字形状部材によって、電源ユニットの上下方向の移動を規制することができる。しかしながら、電源ユニットの車輪が筐体内で回転すると、電源ユニットが筐体内を前後方向又は左右方向に意図せずに移動するおそれがある。 In the invention of Patent Document 1, for example, even if vibrations are applied to the electrical equipment during transportation, the L-shaped member abutting the top plate of the power supply unit can restrict the power supply unit from moving up and down. However, if the wheels of the power supply unit rotate within the housing, there is a risk that the power supply unit will unintentionally move forward and backward or left and right within the housing.
　本発明は、かかる点に鑑みてなされたものであり、その目的は、電源ユニットが筐体内で意図せずに移動するのを抑えるための電源収納構造を提供することにある。 The present invention was made in consideration of these points, and its purpose is to provide a power supply storage structure that prevents the power supply unit from moving unintentionally inside the housing.
　第１の態様は、電源ユニットと、側面に開口部を有する箱状の筐体と、を備え、前記電源ユニットを前記開口部から前記筐体の内部に収納するための電源収納構造であって、前記電源ユニットは、電源本体と、前記電源本体の底部に設けられた車輪と、前記電源本体の底部に設けられた当接部と、を有し、前記筐体は、前記車輪が走行するレール部と、前記レール部よりも収納方向の奥側に設けられ、前記車輪が挿入されることで前記車輪の下部を前記レール部の上面よりも低い位置に移動させる孔部と、前記当接部の下部を支持する支持部と、を有し、前記電源ユニットは、前記当接部が前記支持部よりも上方に離れて配置され、前記車輪が前記レール部を走行可能な第１状態と、前記車輪が前記孔部に挿入されて前記車輪が前記レール部を走行不能となり、且つ前記当接部が前記支持部に支持された第２状態と、に切り替え可能である。 The first aspect is a power supply storage structure that includes a power supply unit and a box-shaped housing having an opening on a side, and is used to store the power supply unit inside the housing through the opening. The power supply unit includes a power supply body, wheels provided on the bottom of the power supply body, and an abutment portion provided on the bottom of the power supply body. The housing includes a rail portion along which the wheels run, a hole portion that is provided on the back side of the rail portion in the storage direction and into which the wheels are inserted to move the lower portion of the wheels to a position lower than the upper surface of the rail portion, and a support portion that supports the lower portion of the abutment portion. The abutment portion is disposed above and spaced apart from the support portion, and the power supply unit is switchable between a first state in which the wheels can run on the rail portion and a second state in which the wheels are inserted into the hole portion, preventing the wheels from running on the rail portion, and the abutment portion is supported by the support portion.
　第１の態様では、電源ユニットを筐体の内部に収納するのにあたって、車輪がレール部を走行可能な第１状態と、車輪がレール部を走行不能な第２状態と、に切り替えるようにしている。第１状態では、電源ユニットの当接部が、筐体の支持部よりも上方に離れて配置される。第２状態では、車輪が孔部に挿入されることで車輪の下部がレール部の上面よりも低い位置に移動して、当接部が支持部に支持される。 In the first aspect, when the power supply unit is stored inside the housing, it is switched between a first state in which the wheels can run on the rail section, and a second state in which the wheels cannot run on the rail section. In the first state, the contact portion of the power supply unit is positioned above and away from the support portion of the housing. In the second state, the wheels are inserted into the holes, causing the lower portion of the wheels to move to a position lower than the top surface of the rail section, and the contact portion is supported by the support portion.
　このように、筐体内の収納方向の奥側において、電源ユニットを第２状態とすることで、車輪をレール部から離れて宙に浮かせたフリーな状態とすることができる。これにより、車輪がレール部を走行不能となり、且つ当接部が支持部で支持された状態となることから、電源ユニットが筐体の内部で前後方向又は左右方向に意図せずに移動するのを抑えることができる。 In this way, by placing the power supply unit in the second state at the rear of the housing in the storage direction, the wheels can be released from the rails and placed in a free state suspended in the air. This prevents the wheels from running on the rails and the abutment parts are supported by the support parts, preventing the power supply unit from moving unintentionally in the front-back or left-right directions inside the housing.
　第２の態様は、第１の態様の電源収納構造において、前記筐体は、収納方向の奥側に立設する後面板を有し、前記後面板の内面側に配置され、前記後面板に沿って上下方向に移動可能な固定部材を備え、前記固定部材は、前記第２状態の前記電源ユニットの上面に当接した位置で、前記後面板に取り付けられる。 In the second aspect, in the power supply storage structure of the first aspect, the housing has a rear panel that stands upright on the rear side in the storage direction, and is equipped with a fixing member that is disposed on the inner side of the rear panel and is movable in the vertical direction along the rear panel, and the fixing member is attached to the rear panel at a position where it abuts against the upper surface of the power supply unit in the second state.
　第２の態様では、第２状態の電源ユニットの上面に固定部材を当接させることで、電源ユニットが筐体の内部で上下方向に意図せずに移動するのを抑えることができる。 In the second aspect, by abutting a fixing member against the top surface of the power supply unit in the second state, it is possible to prevent the power supply unit from unintentionally moving up and down inside the housing.
　第３の態様は、第１又は２の態様の電源収納構造において、前記筐体の下面板における前記開口部側の縁部には、収納方向の手前側に向かって斜め下方に傾斜したスロープ部が設けられる。 In the third aspect, in the power supply storage structure of the first or second aspect, a slope portion is provided on the edge of the bottom plate of the housing on the opening side, which slopes diagonally downward toward the front side in the storage direction.
　第３の態様では、筐体の下面板にスロープ部を設けることで、電源ユニットを筐体の内部に収納する際に、電源ユニットをスロープ部に沿って乗り上げながら、スムーズに移動させることができる。これにより、単独の作業者であっても、車輪をレール部に乗せる作業を、電源ユニットを持ち上げることなく、必要最小限の力で行うことができる。 In the third aspect, by providing a sloped section on the bottom panel of the housing, when the power supply unit is stored inside the housing, the power supply unit can be moved smoothly while climbing up along the sloped section. This allows even a single worker to place the wheels on the rail section with the minimum amount of force required, without having to lift the power supply unit.
　第４の態様は、第１又は２の態様の電源収納構造において、前記筐体は、収納方向に直交する幅方向に立設する左面板及び右面板を有し、前記左面板及び前記右面板の内面側に配置され、前記電源ユニットの幅方向の移動を規制するガイド部材を備える。 The fourth aspect is a power supply storage structure according to the first or second aspect, in which the housing has a left panel and a right panel that stand upright in a width direction perpendicular to the storage direction, and includes guide members that are disposed on the inner side of the left panel and the right panel and that restrict movement of the power supply unit in the width direction.
　第４の態様では、筐体の左面板及び右面板の内面側にガイド部材を設けることで、電源ユニットを筐体の内部で収納方向に移動させる際に、電源ユニットが左右方向に揺れ動くのをガイド部材で規制して、電源ユニットをスムーズに出し入れすることができる。 In the fourth aspect, by providing guide members on the inner sides of the left and right panels of the housing, the guide members can regulate the left-right swinging of the power supply unit when it is moved inside the housing in the storage direction, allowing the power supply unit to be inserted and removed smoothly.
　第５の態様は、第１又は２の態様の電源収納構造において、前記筐体は、前記開口部を塞ぐ前面板を有し、前記前面板と、前記第２状態の前記電源ユニットとは、締結ボルトによって締結される。 In the fifth aspect, in the power supply storage structure of the first or second aspect, the housing has a front plate that closes the opening, and the front plate and the power supply unit in the second state are fastened together by a fastening bolt.
　第５の態様では、電源ユニットを筐体の内部に収納した後、筐体の開口部を前面板で塞ぎ、前面板と電源ユニットとを締結ボルトで締結することで、電源ユニットが筐体の内部で意図せずに移動するのを抑えることができる。また、電源ユニットを筐体内から取り出す際にも、締結ボルトを取り外すだけでよいため、作業性が向上する。 In the fifth aspect, after the power supply unit is stored inside the housing, the opening of the housing is closed with a front panel and the front panel and the power supply unit are fastened with fastening bolts, which prevents the power supply unit from moving unintentionally inside the housing. In addition, when removing the power supply unit from inside the housing, it is only necessary to remove the fastening bolts, improving workability.
　第６の態様は、第５の態様の電源収納構造において、前記筐体の上部に配置され、前記筐体の前記開口部と同じ側にボックス開口部が設けられたコントローラボックスと、前記ボックス開口部を開閉する開閉扉と、を備え、前記前面板の一部は、前記ボックス開口部を閉じた状態の前記開閉扉よりも収納方向の奥側で、前記開閉扉に重なり合うように配置される。 The sixth aspect is the power supply storage structure of the fifth aspect, which includes a controller box arranged on the upper part of the housing and having a box opening on the same side as the opening of the housing, and an opening/closing door for opening and closing the box opening, and a part of the front panel is arranged so as to overlap the opening/closing door, further back in the storage direction than the opening/closing door when the box opening is closed.
　第６の態様では、開閉扉を閉じた状態において前面板を取り外すことができないため、筐体から電源ユニットを取り出すことができない構造となっている。これにより、作業者の安全を確保することができる。 In the sixth aspect, the front panel cannot be removed when the door is closed, so the power supply unit cannot be removed from the housing. This ensures the safety of the workers.
　具体的に、コントローラボックスの開閉扉は、作業者の安全確保のため、コントローラ側の電源をオフにしなければ開くことができない構造となっている。また、筐体の前面板は、開閉扉が開いた状態でなければ、取り外すことができない。そのため、メンテナンスのために、筐体の内部から電源ユニットを取り出そうとした場合に、既に電源ユニットの電源がオフされた状態となっていることから、作業者の安全を確保することができる。 Specifically, to ensure the safety of workers, the door of the controller box is designed so that it cannot be opened unless the power supply on the controller side is turned off. Also, the front panel of the housing cannot be removed unless the door is open. Therefore, when attempting to remove the power supply unit from inside the housing for maintenance, the power supply unit is already turned off, ensuring the safety of workers.
　本開示の態様によれば、電源ユニットが筐体内で意図せずに移動するのを抑えることができる。 According to the aspects of the present disclosure, it is possible to prevent the power supply unit from moving unintentionally within the housing.

　以下、本発明の実施形態を図面に基づいて説明する。なお、以下の好ましい実施形態の説明は、本質的に例示に過ぎず、本発明、その適用物或いはその用途を制限することを意図するものではない。 Below, an embodiment of the present invention will be described with reference to the drawings. Note that the following description of the preferred embodiment is essentially merely an example and is not intended to limit the present invention, its applications, or its uses.
　〈溶接電源装置〉
　図１に示すように、溶接電源装置１は、電源ユニット１０と、筐体２０と、を備える。電源ユニット１０は、電源本体１１と、車輪１２と、取っ手１３と、当接部１４と、締結部１５と、を有する。 <Welding power supply>
1 , the welding power supply 1 includes a power supply unit 10 and a housing 20. The power supply unit 10 includes a power supply main body 11, wheels 12, a handle 13, a contact portion 14, and a fastening portion 15.
　電源本体１１は、筐体２０内に収納可能な大きさの略箱状に形成される。電源本体１１の内部には、図示しないインバータ回路やコイル等が設けられる。電源本体１１は、車輪１２によって移動可能に支持される。 The power supply body 11 is formed in a roughly box-like shape that is large enough to be stored in the housing 20. An inverter circuit, coils, and the like (not shown) are provided inside the power supply body 11. The power supply body 11 is supported by wheels 12 so that it can be moved.
　車輪１２は、電源本体１１の底部に複数設けられる。車輪１２は、例えば、電源本体１１の底部の四隅にそれぞれ設けられる。取っ手１３は、電源本体１１の上部に複数設けられる。取っ手１３は、電源ユニット１０を移動させる際に、作業者が把持する。 Multiple wheels 12 are provided on the bottom of the power supply body 11. For example, the wheels 12 are provided on each of the four corners of the bottom of the power supply body 11. Multiple handles 13 are provided on the top of the power supply body 11. The handles 13 are held by an operator when moving the power supply unit 10.
　当接部１４は、電源本体１１における前後左右の側壁板を、電源本体１１の底部における車輪１２の取付面よりも下方に延ばすことで形成される（図５を参照）。当接部１４の下端部は、車輪１２の下部よりも上方に配置される。 The abutment portion 14 is formed by extending the front, rear, left and right side wall panels of the power supply body 11 downward from the mounting surface of the wheels 12 at the bottom of the power supply body 11 (see FIG. 5). The lower end of the abutment portion 14 is positioned above the lower part of the wheels 12.
　締結部１５は、電源本体１１の底板における収納方向の手前側の縁部を下方に折り曲げることで形成される。締結部１５には、ネジ孔１６が形成される。 The fastening portion 15 is formed by bending downward the edge of the bottom plate of the power supply body 11 on the front side in the storage direction. A screw hole 16 is formed in the fastening portion 15.
　図２及び図３にも示すように、筐体２０は、略箱状に形成される。筐体２０は、前面板２１と、後面板２２と、左面板２３と、右面板２４と、上面板２５と、下面板３０と、を有する。 As shown in Figures 2 and 3, the housing 20 is formed in a generally box-like shape. The housing 20 has a front panel 21, a rear panel 22, a left panel 23, a right panel 24, a top panel 25, and a bottom panel 30.
　筐体２０は、側面に開口部２６を有する箱状に形成される。開口部２６は、筐体２０の前側に開口する。電源ユニット１０は、筐体２０の開口部２６から筐体２０の内部に収納される。 The housing 20 is formed in a box shape with an opening 26 on the side. The opening 26 opens to the front side of the housing 20. The power supply unit 10 is stored inside the housing 20 through the opening 26 of the housing 20.
　前面板２１は、開口部２６を塞ぐ。前面板２１は、筐体２０に電源ユニット１０を収納する際、又は筐体２０から電源ユニット１０を取り出してメンテナンスを行う際に、筐体２０から取り外される。 The front panel 21 covers the opening 26. The front panel 21 is removed from the housing 20 when storing the power supply unit 10 in the housing 20, or when removing the power supply unit 10 from the housing 20 for maintenance.
　前面板２１には、電源ユニット１０の締結部１５のネジ孔１６に対応する位置に、図示しない孔が形成される。前面板２１と締結部１５とは、締結ボルト１８によって締結される。これにより、電源ユニット１０が筐体２０の内部で意図せずに移動するのを抑えることができる。 The front plate 21 has holes (not shown) formed at positions corresponding to the screw holes 16 of the fastening portion 15 of the power supply unit 10. The front plate 21 and the fastening portion 15 are fastened together by fastening bolts 18. This makes it possible to prevent the power supply unit 10 from moving unintentionally inside the housing 20.
　図４に示すように、下面板３０には、レール溝３１が形成される。レール溝３１は、電源ユニット１０の車輪１２が通過する位置に形成される。図４に示す例では、レール溝３１は、下面板３０の左右方向に間隔をあけて２つ形成される。レール溝３１は、収納方向の手前側に開口している。レール溝３１の収納方向の奥側には、車輪１２との干渉を避けるための切欠部３２が形成される。下面板３０は、レール溝３１の左右の縁部に沿って下方に折り曲げられた折り曲げ部３３を有する。 As shown in FIG. 4, a rail groove 31 is formed in the bottom plate 30. The rail groove 31 is formed at a position where the wheels 12 of the power supply unit 10 pass. In the example shown in FIG. 4, two rail grooves 31 are formed at a distance in the left-right direction of the bottom plate 30. The rail groove 31 opens on the front side in the storage direction. A cutout portion 32 is formed on the rear side of the rail groove 31 in the storage direction to avoid interference with the wheels 12. The bottom plate 30 has bent portions 33 bent downward along the left and right edges of the rail groove 31.
　下面板３０は、スロープ部３５と、レール部３６と、孔部３７と、支持部３８と、を有する。スロープ部３５は、下面板３０における、筐体２０の開口部２６側の縁部に設けられる。スロープ部３５は、収納方向の手前側に向かって斜め下方に傾斜して延びる。 The bottom panel 30 has a slope portion 35, a rail portion 36, a hole portion 37, and a support portion 38. The slope portion 35 is provided on the edge of the bottom panel 30 on the side of the opening 26 of the housing 20. The slope portion 35 extends obliquely downward toward the front side in the storage direction.
　これにより、電源ユニット１０を筐体２０内に収納する際に、電源ユニット１０を傾斜させ、スロープ部３５に沿って乗り上げながら、スムーズに移動させることができる（図５参照）。これにより、単独の作業者であっても、車輪１２をレール部３６に乗せる作業を、電源ユニット１０をフロア面から完全に離間して持ち上げることなく、傾ける程度の必要最小限の力で行うことができる。 As a result, when storing the power supply unit 10 inside the housing 20, the power supply unit 10 can be tilted and moved smoothly while climbing up along the slope portion 35 (see FIG. 5). This allows even a single worker to place the wheels 12 on the rail portion 36 with the minimum necessary force, just enough to tilt the power supply unit 10, without having to lift it completely off the floor surface.
　レール部３６は、上方が開口するように折り曲げられた凹状の板材で形成される。レール部３６の側壁が下面板３０の折り曲げ部３３に固定されることで、下面板３０の上面よりも下方にレール部３６が配置される。レール部３６の下面は、折り曲げ部３３の下端部よりも上方に配置される。電源ユニット１０の車輪１２は、レール部３６を走行する。 The rail section 36 is formed from a plate material that is bent in a concave shape so that it opens upward. The side walls of the rail section 36 are fixed to the bent section 33 of the lower panel 30, so that the rail section 36 is positioned below the upper surface of the lower panel 30. The lower surface of the rail section 36 is positioned above the lower end of the bent section 33. The wheels 12 of the power supply unit 10 run on the rail section 36.
　孔部３７は、レール部３６よりも収納方向の奥側に設けられる。孔部３７は、平面視で、切欠部３２とレール部３６の奥側端部との間に設けられた開口孔で形成される。孔部３７は、車輪１２が挿入されることで、車輪１２の下部をレール部３６の上面よりも低い位置に移動させる。 The hole 37 is provided on the rear side of the rail portion 36 in the storage direction. In a plan view, the hole 37 is formed as an opening hole provided between the cutout portion 32 and the rear end portion of the rail portion 36. When the wheel 12 is inserted into the hole 37, the lower portion of the wheel 12 moves to a position lower than the upper surface of the rail portion 36.
　支持部３８は、電源ユニット１０における当接部１４の下部を支持する。詳しくは後述するが、本実施形態では、支持部３８は、下面板３０の上面部分である。当接部１４が下面板３０の上面に載置されることで、当接部１４の下部が支持部３８と当接し支持部３８で支持される。 The support portion 38 supports the lower portion of the abutment portion 14 of the power supply unit 10. As will be described in more detail later, in this embodiment, the support portion 38 is the upper surface portion of the lower panel 30. When the abutment portion 14 is placed on the upper surface of the lower panel 30, the lower portion of the abutment portion 14 abuts against the support portion 38 and is supported by the support portion 38.
　図５に示すように、電源ユニット１０を筐体２０内に収納していくと、電源ユニット１０がスロープ部３５に沿って（具体的には、当接部１４がスロープ部３５に乗り上げながら滑走するようにして、電源ユニット１０が傾いて先端側が持ち上がりながら）移動するとともに、車輪１２がレール部３６の上面に乗り上げる。このとき、当接部１４は、支持部３８としての下面板３０の上面よりも上方に離れて配置される。このように、当接部１４が支持部３８よりも上方に離れて配置され、車輪１２がレール部３６を走行可能な状態を、第１状態とする。 As shown in FIG. 5, when the power supply unit 10 is stored inside the housing 20, the power supply unit 10 moves along the slope portion 35 (specifically, the abutment portion 14 slides up the slope portion 35, causing the power supply unit 10 to tilt and lift up at the tip), and the wheels 12 climb onto the upper surface of the rail portion 36. At this time, the abutment portion 14 is positioned above and away from the upper surface of the lower panel 30, which serves as the support portion 38. In this way, the state in which the abutment portion 14 is positioned above and away from the support portion 38 and the wheels 12 can run on the rail portion 36 is referred to as the first state.
　図６に示すように、電源ユニット１０をさらに筐体２０内の奥側に収納していくと、車輪１２が孔部３７に挿入されることで車輪１２の下部がレール部３６の上面よりも低い位置に移動する。このとき、当接部１４は、支持部３８としての下面板３０の上面に支持される（図７も参照）。また、車輪１２は、レール部３６から離れて宙に浮いたフリーな状態となる。このように、車輪１２が孔部３７に挿入されて車輪１２がレール部３６を走行不能となり、且つ当接部１４が支持部３８に支持された状態を、第２状態とする。 As shown in FIG. 6, when the power supply unit 10 is stored further into the housing 20, the wheels 12 are inserted into the holes 37, causing the lower parts of the wheels 12 to move to a position lower than the upper surface of the rail portion 36. At this time, the abutment parts 14 are supported by the upper surface of the lower panel 30, which serves as the support part 38 (see also FIG. 7). The wheels 12 are also separated from the rail portion 36 and are in a free state suspended in mid-air. The state in which the wheels 12 are inserted into the holes 37 and cannot run on the rail portion 36, and the abutment parts 14 are supported by the support part 38, is referred to as the second state.
　本実施形態では、電源ユニット１０を筐体２０の内部に収納するのにあたって、車輪１２がレール部３６を走行可能な第１状態と、車輪１２がレール部３６を走行不能な第２状態と、に切り替えるようにしている。 In this embodiment, when storing the power supply unit 10 inside the housing 20, the state is switched between a first state in which the wheels 12 can run on the rail portion 36 and a second state in which the wheels 12 cannot run on the rail portion 36.
　これにより、筐体２０内の収納方向の奥側において、電源ユニット１０を第２状態とすることで、車輪１２がレール部３６を走行不能となり、且つ当接部１４が支持部３８に当接し支持部３８で支持された状態となることから、電源ユニット１０が筐体２０の内部で前後方向又は左右方向に意図せずに移動するのを抑えることができる。 As a result, by placing the power supply unit 10 in the second state at the rear of the housing 20 in the storage direction, the wheels 12 cannot travel on the rails 36, and the abutment parts 14 abut against the supports 38 and are supported by the supports 38, preventing the power supply unit 10 from moving unintentionally in the front-to-back or left-to-right directions inside the housing 20.
　図８及び図９に示すように、筐体２０は、固定部材４０と、左右一対のガイド部材４１と、を備える。固定部材４０は、筐体２０の後面板２２の内面側に配置される。固定部材４０は、断面略Ｌ字状に折り曲げられた板材で形成される。 As shown in Figures 8 and 9, the housing 20 includes a fixed member 40 and a pair of left and right guide members 41. The fixed member 40 is disposed on the inner surface side of the rear panel 22 of the housing 20. The fixed member 40 is formed from a plate material bent into a substantially L-shaped cross section.
　後面板２２には、上下方向に延びる図示しない長孔が形成される。固定部材４０は、長孔に挿通された締結ボルト１８によって、後面板２２に締結される。固定部材４０は、締結ボルト１８を緩めることで、後面板２２に沿って上下方向に移動可能となっている。固定部材４０は、車輪１２を走行不能とした第２状態の電源ユニット１０の上面に当接した位置で、後面板２２に取り付けられる。 The rear plate 22 has a long hole (not shown) that extends in the vertical direction. The fixing member 40 is fastened to the rear plate 22 by a fastening bolt 18 that is inserted into the long hole. The fixing member 40 can be moved in the vertical direction along the rear plate 22 by loosening the fastening bolt 18. The fixing member 40 is attached to the rear plate 22 at a position where it abuts against the upper surface of the power supply unit 10 in the second state in which the wheels 12 are disabled from traveling.
　このように、電源ユニット１０を第２状態とした後で、電源ユニット１０の上面に固定部材４０を当接させることで、電源ユニット１０が筐体２０の内部で上下方向に意図せずに移動するのを抑えることができる。 In this way, by abutting the fixing member 40 against the upper surface of the power supply unit 10 after the power supply unit 10 is placed in the second state, it is possible to prevent the power supply unit 10 from unintentionally moving up and down inside the housing 20.
　ガイド部材４１は、左面板２３及び右面板２４の内面側にそれぞれ配置される。ガイド部材４１は、収納方向に沿って延びる板材で形成される。左右のガイド部材４１の間の距離は、電源ユニット１０の幅方向の長さと略同じ寸法になるように設定される。左右のガイド部材４１は、電源ユニット１０の幅方向の移動を規制する。 The guide members 41 are disposed on the inner sides of the left panel 23 and the right panel 24. The guide members 41 are formed from a plate material extending along the storage direction. The distance between the left and right guide members 41 is set to be approximately the same dimension as the width of the power supply unit 10. The left and right guide members 41 regulate the movement of the power supply unit 10 in the width direction.
　このように、筐体２０の左面板２３及び右面板２４の内面側にガイド部材４１を設けることで、電源ユニット１０を筐体２０の内部で収納方向に移動させる際に、電源ユニット１０が左右方向に揺れ動くのをガイド部材４１で規制して、電源ユニット１０をスムーズに出し入れすることができる。 In this way, by providing guide members 41 on the inner surfaces of the left panel 23 and right panel 24 of the housing 20, the guide members 41 regulate the left-right swinging of the power supply unit 10 when moving the power supply unit 10 inside the housing 20 in the storage direction, allowing the power supply unit 10 to be inserted and removed smoothly.
　〈コントローラボックス〉
　ここで、本実施形態の溶接電源装置１は、例えば、産業用ロボットとともに使用されるものである。図１０に示すように、溶接電源装置１の上に産業用ロボットのロボット制御装置５０を配置し、溶接電源装置１とロボット制御装置５０と、を一体とした機器として使用することもできる。 <Controller box>
Here, the welding power supply 1 of this embodiment is used together with, for example, an industrial robot. As shown in Fig. 10, a robot controller 50 for an industrial robot can be disposed on the welding power supply 1, and the welding power supply 1 and the robot controller 50 can be used as an integrated device.
　図１０及び図１１に示すように、ロボット制御装置５０は、コントローラボックス５１と、コントローラ５２と、を備える。コントローラボックス５１は、溶接電源装置１の筐体２０の上部に載置される。コントローラ５２は、コントローラボックス５１の内部に収納される。 As shown in Figures 10 and 11, the robot control device 50 includes a controller box 51 and a controller 52. The controller box 51 is placed on top of the housing 20 of the welding power supply 1. The controller 52 is stored inside the controller box 51.
　コントローラボックス５１には、ボックス開口部５３が設けられる。ボックス開口部５３は、筐体２０の開口部２６と同じ側に開口する。コントローラボックス５１は、開閉扉５４を有する。開閉扉５４は、ボックス開口部５３を開閉可能に塞ぐ。開閉扉５４は、蝶番５５を介してコントローラボックス５１に取り付けられる。 The controller box 51 is provided with a box opening 53. The box opening 53 opens on the same side as the opening 26 of the housing 20. The controller box 51 has an opening/closing door 54. The opening/closing door 54 closes the box opening 53 in an openable/closable manner. The opening/closing door 54 is attached to the controller box 51 via a hinge 55.
　ここで、図１２に示すように、筐体２０の前面板２１の一部、つまり、前面板２１の上端部分は、ボックス開口部５３を閉じた状態の開閉扉５４よりも収納方向の奥側で、開閉扉５４に重なり合うように配置される。そのため、開閉扉５４を閉じた状態では、前面板２１を筐体２０から取り外すことができないようになっている。 As shown in FIG. 12, a part of the front panel 21 of the housing 20, i.e., the upper end portion of the front panel 21, is positioned so as to overlap the opening and closing door 54, further back in the storage direction than the opening and closing door 54 when the box opening 53 is closed. Therefore, when the opening and closing door 54 is closed, the front panel 21 cannot be removed from the housing 20.
　一方、図１３に示すように、開閉扉５４を閉じた状態から開いた状態とすると、前面板２１の上端部分が露出して、前面板２１を筐体２０から取り外すことが可能となる。 On the other hand, as shown in FIG. 13, when the opening and closing door 54 is opened from a closed state, the upper end portion of the front panel 21 is exposed, making it possible to remove the front panel 21 from the housing 20.
　このようにすれば、作業者の安全を確保することができる。具体的に、コントローラボックス５１の開閉扉５４は、作業者の安全確保のため、コントローラ５２側の電源をオフにしなければ開くことができない構造となっている。また、筐体２０の前面板２１は、開閉扉５４が開いた状態でなければ、取り外すことができない。そのため、メンテナンスのために、筐体２０の内部から電源ユニット１０を取り出そうとした場合に、既に電源がオフされた状態となっていることから、作業者の安全を確保することができる。 In this way, the safety of the worker can be ensured. Specifically, the opening and closing door 54 of the controller box 51 is structured so that it cannot be opened unless the power supply on the controller 52 side is turned off, in order to ensure the safety of the worker. Furthermore, the front panel 21 of the housing 20 cannot be removed unless the opening and closing door 54 is in an open state. Therefore, when attempting to remove the power supply unit 10 from inside the housing 20 for maintenance, the power supply has already been turned off, ensuring the safety of the worker.
　以上説明したように、本発明は、電源ユニットが筐体内で意図せずに移動するのを抑えることができるという実用性の高い効果が得られることから、きわめて有用で産業上の利用可能性は高い。 As explained above, the present invention has the highly practical effect of preventing the power supply unit from moving unintentionally inside the housing, making it extremely useful and highly applicable industrially.
