本発明は、装置の組立作業を行う組立箇所を通る移動ラインに沿って複数台の移動台車を設定間隔で並べた台車列を形成する状態で移動させる移動装置が設けられ、前記移動台車が、組立対象の装置を支持した状態で前記移動ラインに沿って移動するように構成されている生産設備に関する。   The present invention is provided with a moving device that moves in a state of forming a carriage row in which a plurality of moving carriages are arranged at set intervals along a moving line that passes through an assembly location where the apparatus is assembled. The present invention relates to a production facility configured to move along the movement line in a state where an apparatus to be assembled is supported.

上記生産設備では、台車列を形成する状態で移動ラインに沿って並ぶ複数の移動台車が移動装置により組立箇所を通る移動ラインに沿って移動され、装置の組立作業を行う作業者が、組立箇所に順次移動してくる移動台車に対して、その移動台車上に組立対象の装置を組み立てるようにして装置が生産される。
このような生産設備では、台車列を移動させる移動装置としてチェーンコンベヤやローラコンベヤを移動ラインに沿って配設し、これらのコンベヤにて複数の移動台車を台車列を形成した状態で移動させるコンベヤ搬送方式が採用されることがある。
しかしながらこのようなコンベヤ搬送方式であると、移動台車を所望の移動状態で例えば、一定の移動速度で安定して移動させることができるものの、移動ラインの全体に亘ってコンベヤを配設することになるため設備構成が複雑になる。
このような問題に対して従来から、設備の簡素化を図るべく、移動装置が、台車移動方向で台車列の下流端部に位置する台車を被牽引台車として移動させるように構成されたものがある(特許文献1の図2等参照。)。
特許文献1の生産設備では、台車列の下流側端部に設けられた移動装置(搬送手段20)が備える係合部(牽引部材24)が、台車が備える被係合部(フック1d)に係合した状態で台車移動方向に移動することで、台車列の下流端部に位置する台車が移動される。これにより、当該下流端部の台車に連結されている上流側の複数の台車が台車移動方向に移動される。そして、移動装置の係合部は台車列の下流端部で巡回移動するように構成されており、係合部が循環移動するに伴って係合部が係合する被牽引台車が上流側の台車に順次切り換わることで、台車列を連続して移動させることができるようになっている。
In the above production facility, a plurality of moving carriages arranged along a movement line in a state where a carriage row is formed are moved along a movement line passing through an assembly place by a moving device, and an operator who performs assembly work of the apparatus is The apparatus is produced by assembling the apparatus to be assembled on the moving carriage with respect to the moving carriage that sequentially moves.
In such production facilities, chain conveyors and roller conveyors are arranged along the movement line as moving devices for moving the carriage train, and these conveyors move a plurality of movable carriages in a state where the carriage train is formed. A conveyance method may be employed.
However, with such a conveyor transport system, the moving carriage can be moved stably in a desired moving state, for example, at a constant moving speed, but the conveyor is arranged over the entire moving line. This complicates the equipment configuration.
Conventionally with respect to such a problem, in order to simplify the equipment, the moving device is configured to move the carriage located at the downstream end of the carriage row in the carriage movement direction as the towed carriage. Yes (see FIG. 2 etc. of Patent Document 1).
In the production facility of Patent Document 1, the engaging portion (the pulling member 24) provided in the moving device (conveying means 20) provided at the downstream end of the carriage row is used as the engaged portion (hook 1d) provided in the carriage. By moving in the moving direction of the carriage in the engaged state, the carriage located at the downstream end of the carriage row is moved. Accordingly, the plurality of upstream carts connected to the cart at the downstream end is moved in the cart movement direction. The engaging portion of the moving device is configured to make a circular movement at the downstream end portion of the carriage row, and the towed cart to which the engaging portion engages as the engaging portion circulates is upstream. By sequentially switching to the bogie, the bogie train can be moved continuously.

特開2000−229727号公報JP 2000-229727 A

上記特許文献1の生産設備では、係合部が循環移動するに伴って係合部が係合する被牽引台車が上流側の移動台車に順次切り換わるため、係合部が移動台車に対して係合して牽引力が作用する状態が断続的に発生することになる。特許文献1のものでは、移動装置の係合部が巡回移動する範囲は、台車列の下流端部の移動台車の1台が存在する範囲となっているため、係合部が移動台車に係合した状態で牽引する距離もその範囲に制限されることになり、移動装置により移動台車を長く継続して牽引することができない。
このように、特許文献1のものでは、被牽引台車が牽引される範囲が下流側端部に制限されており、被牽引台車が上流側から移動してくる次の移動台車に頻繁に切り換わる度に台車列は加速と減速とを繰り返すことになり、係合対象の移動台車が頻繁に切り換わることで加減速や衝撃が頻繁に発生し、組立箇所における作業に悪影響を及ぼすおそれがある。
In the production facility of Patent Document 1, the towed truck with which the engaging part engages is sequentially switched to the upstream moving carriage as the engaging part circulates and moves, so that the engaging part moves with respect to the moving carriage. A state in which the traction force is engaged and intermittently occurs. In the case of Patent Document 1, the range in which the engaging portion of the moving device moves in a cyclic manner is a range in which one moving carriage at the downstream end of the carriage row exists, and therefore the engaging portion is associated with the moving carriage. The distance to be pulled in the combined state is also limited to the range, and the moving carriage cannot be continuously pulled by the moving device.
Thus, in the thing of patent document 1, the range by which a towed cart is pulled is restrict | limited to the downstream edge part, and the towed cart switches frequently to the next moving cart which moves from the upstream side. Each time the bogie train repeats acceleration and deceleration, frequent switching of the moving bogie to be engaged frequently causes acceleration / deceleration and impact, which may adversely affect the work at the assembly location.

本発明は上記実状に鑑みて為されたものであって、その目的は、簡素な構成により台車列を極力円滑に移動させることができる生産設備を提供する点にある。   This invention is made | formed in view of the said actual condition, The objective is to provide the production equipment which can move a trolley | bogie row | line | column as smoothly as possible by simple structure.

この目的を達成するために、本発明に係る生産設備の第1特徴構成は、装置の組立作業を行う組立箇所を通る移動ラインに沿って複数台の移動台車を設定間隔で並べた台車列を形成する状態で移動させる移動装置が設けられ、前記移動台車が、組立対象の装置を支持した状態で前記移動ラインに沿って移動するように構成されている生産設備において、
前記移動装置が、台車移動方向に沿って移動自在に設けられた係合部と、前記係合部を移動させる移動駆動部と、を備え、前記複数の移動台車の夫々が、前記係合部と係合する被係合部を備え、且つ、台車移動方向で一方側に隣接する移動台車が備える被連結部に連結自在な連結部を、連結状態において隣接する移動台車を押し引き操作可能な状態で備え、前記移動ライン上に、前記係合部を前記移動台車における前記被係合部に係合させる牽引開始位置と、前記台車列を形成する状態の複数の移動台車のうち前記牽引開始位置で前記係合部が係合した前記移動台車を被牽引台車としてこの被牽引台車の下流側に隣接する移動台車よりさらに下流側の位置であって前記係合部を前記被牽引台車における前記被係合部から離脱させる位置としての牽引終了位置とが設定され、前記移動装置は、前記被牽引台車における前記被係合部に前記係合部を係合させた状態で、前記牽引開始位置から前記牽引終了位置まで前記被牽引台車を移動させるように構成され、前記移動装置が、前記移動駆動部として、前記係合部を先端に備えた索状体と、この索状体を巻き取る巻取部とを備え、前記組立箇所において行われる複数の工程に対応する作業箇所が、移動ラインに沿って並ぶ状態で設定され、前記複数の作業箇所として、前記移動ラインに沿って移動する前記移動台車が通過させるための進入用開口及び退出用開口が形成された区画壁にて外部から仕切られた閉鎖作業箇所が設定され、前記牽引開始位置が、前記移動ラインにおける前記移動台車の移動方向で前記閉鎖作業箇所の下流側に設定されている点にある。
In order to achieve this object, the first characteristic configuration of the production facility according to the present invention includes a carriage train in which a plurality of movable carriages are arranged at set intervals along a movement line passing through an assembly location where the apparatus is assembled. In a production facility provided with a moving device that moves in a state of forming, the moving carriage is configured to move along the moving line while supporting the device to be assembled,
The moving device includes an engaging portion that is movably provided along a carriage moving direction, and a movement driving unit that moves the engaging portion, and each of the plurality of moving carriages includes the engaging portion. A connecting portion that can be connected to a connected portion provided in a moving carriage adjacent to one side in the moving direction of the carriage, and can push and pull the adjacent moving carriage in the connected state. A traction start position for engaging the engagement portion with the engaged portion of the movable carriage on the movement line, and the traction start among a plurality of movable carriages in a state of forming the carriage row The moving carriage engaged with the engaging portion at a position is a towed carriage, and is located further downstream than the moving carriage adjacent to the downstream side of the towed carriage, and the engaging portion is located on the towed carriage. As a position to disengage from the engaged part A tow end position is set, and the moving device is configured to move the towed carriage from the tow start position to the tow end position in a state where the engaging part is engaged with the engaged part of the towed carriage. And the moving device includes, as the movement drive unit, a cord-like body provided with the engaging portion at a tip thereof, and a winding unit that winds the cord-like body, and the assembly location The work locations corresponding to the plurality of steps performed in the step are set in a state of being aligned along the movement line, and as the plurality of work locations, the entrance opening for allowing the moving carriage moving along the movement line to pass therethrough And a closing work location partitioned from the outside by a partition wall in which an exit opening is formed, and the traction start position is set downstream of the closing work location in the movement direction of the movable carriage in the movement line. It lies in the fact that is.

本特徴構成によれば、複数の移動台車は、夫々が備える連結部により互いに連結された状態で台車列を形成する。この連結部により連結された複数の移動台車は、互いに押し引き操作可能な状態となっている。そのため、台車列を形成する状態の複数の移動台車のうち一台を被牽引台車として、この被牽引台車における被係合部に移動装置の係合部を係合させた状態で移動装置が当該被牽引台車を移動させることで、台車移動方向で被牽引台車の上流側に位置する移動台車を引き操作することができ、同時に、台車移動方向で被牽引台車の下流側に位置する移動台車を押し操作することができる。
したがって、被牽引台車を牽引開始位置から牽引開始位置より台車移動方向で下流側の牽引終了位置まで移動させる間、係合部を当該被牽引台車の被係合部に係合させた状態を維持したまま台車列を移動させることができる。そのため、一台の移動台車に係合部を形動させた後は、その移動台車を被牽引台車として、牽引開始位置で当該被牽引台車に係合部を係合させたときに台車移動方向で下流側に連結されている移動台車の数に相当する距離だけ移動装置により継続して牽引することができる。なお、被牽引台車が牽引終了位置まで移動が完了した場合は、そのときに牽引開始位置に位置している移動台車を次の被牽引台車として、新たな被牽引台車における被係合部に係合させるべく、移動装置の係合部を台車移動方向で上流側に復帰移動させればよい。係合部を復帰移動させて新たな被牽引台車における被係合部に係合させる処理は、作業者が行うことが好ましいが、自動で行うことも考えられる。
このように、本特徴構成によれば、被牽引台車が牽引される範囲が下流側端部のみならず、台車列の下流側端部よりも上流側に位置する移動台車を被牽引台車として牽引することが可能であるため、被牽引台車が上流側から移動してくる次の移動台車に頻繁に切り換わることが抑制され、被牽引台車の切り換わりに伴う衝撃を極力発生させずに台車列を円滑に移動させることができる。
According to this characteristic configuration, the plurality of mobile trolleys form a trolley train in a state where they are connected to each other by the connecting portions included therein. The plurality of mobile trolleys connected by this connecting portion are in a state where they can be pushed and pulled. For this reason, one of the plurality of moving carriages in a state of forming a carriage row is used as a towed carriage, and the moving device is engaged in a state where the engaging portion of the moving device is engaged with the engaged portion of the towed carriage. By moving the towed carriage, it is possible to pull and operate the moving carriage that is located upstream of the towed truck in the direction of carriage movement, and at the same time, the moving carriage that is located downstream of the towed carriage in the direction of carriage movement. Can be pushed.
Therefore, while the towed truck is moved from the tow start position to the tow end position downstream from the tow start position in the carriage moving direction, the state where the engaging part is engaged with the engaged part of the towed truck is maintained. The carriage train can be moved as it is. Therefore, after moving the engaging part to one moving carriage, the moving direction of the carriage when the engaging part is engaged with the towed carriage at the towing start position with the moving carriage as a towed carriage Thus, it is possible to continue towing by the moving device for a distance corresponding to the number of moving carriages connected to the downstream side. When the towed carriage is completely moved to the tow end position, the moving carriage at the tow start position at that time is set as the next towed truck and the engaged part in the new towed truck is engaged. In order to match, the engaging portion of the moving device may be returned to the upstream side in the carriage moving direction. The operator preferably performs the process of returning the engaging portion to engage with the engaged portion in the new towed carriage, but it is also conceivable to perform it automatically.
Thus, according to this characteristic configuration, the towed truck is towed not only at the downstream end but also as the towed carriage at the upstream side of the downstream end of the carriage row. As a result, it is possible to prevent the towed carriage from frequently switching to the next moving carriage that moves from the upstream side, and to create a train train without generating as much impact as possible. Can be moved smoothly.

また、本特徴構成によれば、移動装置は、フック等の係合部を先端部に備えたワイヤ等の索状体と、この索状体を巻き取るウィンチ等の巻取部により構成された簡素なものとなる。組立箇所には、複数の作業箇所が移動ラインに沿って並ぶ状態で設定され、そのうちの一つ又は複数の作業箇所が閉鎖作業箇所として構成される。閉鎖作業箇所は、進入用開口及び退出用開口が形成された区画壁にて外部から仕切られており、台車列を形成する移動台車は、上流側から進入用開口を通過して閉鎖作業箇所に進入し、下流側から退出用開口を通過して閉鎖作業箇所から退出する形態で、閉鎖作業箇所を通過できる。つまり、台車列は、閉鎖作業箇所を貫通する形態で移動することになる。
このような閉鎖作業箇所を設定することで、閉鎖作業箇所では、例えば、機械加工等で加工された金属部品に残留する加工切粉屑の付着異物や、生産設備が設置される工場内の雰囲気中に存在する塵埃等の異物の影響を受け難い状態で、作業を行うことができる。また、生産設備が設置される工場等の空間に飛散させたくない材料(例えば、オイル等)を扱う作業工程を、移動台車を移動ラインから離脱させることなく、複数の工程の途中の工程で行うことができる。
移動ラインに沿う作業箇所として区画壁にて外部から仕切られた閉鎖作業箇所が設定されると、被牽引台車を切り換えるべく移動装置の係合部を復帰移動させて閉鎖作業箇所より台車移動方向で上流側の移動台車に索状体の先端部の係合部を係合させようとすると、閉鎖作業箇所における区画壁における進入用開口及び退出用開口に、索状体の先端側を通過させる煩わしい作業が必要となる。
この点、本特徴構成によると、牽引開始位置が、移動ラインにおける台車列の移動方向で閉鎖作業箇所の下流側に設定されているため、移動装置の係合部を復帰移動させる場合に閉鎖作業箇所を索状体の先端側を通過させる煩わしさがなく、被係合台車の切り換えが行い易い。
In addition, according to the present characteristic configuration, the moving device is configured by a cable-like body such as a wire having an engagement portion such as a hook at the distal end portion, and a winding portion such as a winch that winds the cord-like body. It will be simple. In the assembly location, a plurality of work locations are set in a line along the movement line, and one or more of the work locations are configured as closed work locations. The closing work site is partitioned from the outside by a partition wall in which an entrance opening and an exit opening are formed, and the mobile carriage forming the carriage train passes through the entrance opening from the upstream side to the closing work site. It is possible to pass through the closing work site in a form that enters, exits the closing work site through the exit opening from the downstream side. That is, the carriage train moves in a form that penetrates the closing work location.
By setting such a closed work location, in the closed work location, for example, foreign matter adhering to machined chips remaining on metal parts processed by machining, etc., or the atmosphere in the factory where the production equipment is installed The work can be performed in a state in which it is not easily affected by foreign matter such as dust existing therein. Also, work processes that handle materials (such as oil) that you do not want to scatter in spaces such as factories where production equipment is installed are performed in the middle of multiple processes without leaving the mobile carriage off the movement line. be able to.
When a closed work location that is partitioned from the outside by a partition wall is set as a work location along the movement line, the engagement portion of the moving device is moved back to switch the towed cart in the direction of carriage movement from the closed work location. When trying to engage the engaging portion of the tip of the cord-like body with the upstream moving carriage, it is troublesome to pass the tip side of the cord-like body through the entrance opening and the exit opening in the partition wall at the closing work location Work is required.
In this regard, according to the present feature configuration, the towing start position is set downstream of the closing work location in the moving direction of the carriage train in the moving line, so that the closing work is performed when the engaging portion of the moving device is moved back. There is no inconvenience of passing the point through the distal end side of the cord-like body, and the engaged cart is easily switched.

本発明に係る生産設備の第特徴構成は、前記移動台車が備える案内ローラと係合して前記移動台車の移動を案内する案内レールが前記移動ラインに沿って設けられ、前記案内レールは、前記案内ローラが離脱自在な不連続箇所を備えている点にある。 According to a second characteristic configuration of the production facility according to the present invention, a guide rail that engages with a guide roller included in the movable carriage and guides the movement of the movable carriage is provided along the movement line, The guide roller has a discontinuous portion that can be separated.

本特徴構成によれば、案内レールが備える不連続箇所から、移動台車が備える案内ローラを離脱させることができる。そのため、台車列を形成する複数の移動台車のうち何れかの移動台車上で組み立てられている装置に何らかの組立不良が発生した場合、当該移動台車における連結部及び被連結部に連結している上流側及び下流側の移動台車との連結を解除すれば、当該移動台車を移動ラインから離脱させることができ、使い勝手がよい。   According to this characteristic configuration, the guide roller included in the moving carriage can be separated from the discontinuous portion included in the guide rail. Therefore, when any assembly failure occurs in an apparatus assembled on any one of the plurality of mobile trolleys forming the trolley train, the upstream connected to the connecting portion and the connected portion in the mobile trolley. If the connection with the side and downstream side mobile trolleys is released, the mobile trolley can be detached from the travel line, which is convenient.

本発明に係る生産設備の第特徴構成は、前記移動台車に、組立対象の前記装置を固定状態で支持自在な装置支持板が設けられ、前記装置支持板が、台車移動方向に隣接する2台の前記移動台車が接触している状態で、一方の前記移動台車に載置支持された前記装置支持板と他方の前記移動台車に載置支持された前記装置支持板との間に前記移動台車の移動方向に隙間が形成される大きさである点にある。 According to a third characteristic configuration of the production facility according to the present invention, the movable carriage is provided with an apparatus support plate that can support the apparatus to be assembled in a fixed state, and the apparatus support plate is adjacent to the movement direction of the carriage. The movement between the device support plate placed and supported on one of the movable carriages and the device support plate placed and supported on the other movable carriage in a state where the movable carriages of the table are in contact with each other It is in a size that a gap is formed in the moving direction of the carriage.

本特徴構成によれば、台車移動方向に隣接する2台の移動台車が、連結部及び被連結部にて連結されずに接触している状態でも、一方の移動台車に載置支持されている装置支持板と他方の移動台車に載置支持されている装置支持板との間に台車移動方向に隙間が形成されている。そのため、2台の移動台車が接触する程度に近づいた場合でも、その2台の移動台車の装置支持板の間に隙間が形成されることで装置支持板の間に作業者の指が挟まれる事故の発生を未然に防止することができる。   According to this characteristic configuration, two moving carts adjacent in the cart moving direction are placed and supported on one moving cart even when they are in contact with each other without being connected at the connecting portion and the connected portion. A gap is formed in the direction of carriage movement between the apparatus support plate and the apparatus support plate placed and supported on the other movable carriage. For this reason, even when the two mobile carriages are close to contact with each other, a gap is formed between the apparatus support plates of the two mobile carriages, thereby causing an accident that an operator's finger is caught between the apparatus support plates. It can be prevented in advance.

次に、移動台車8について説明する。
図4〜図7に示すように、移動台車8には、装置支持板10を水平方向に移動自在に載置支持する組立用支持部13と、組立用支持部13に支持された装置支持板10の水平方向への移動を規制した規制状態及び当該規制を解除した規制解除状態に切換自在な移動規制機構14と、が備えられている。
Next, the movable carriage 8 will be described.
As shown in FIGS. 4 to 7, the movable carriage 8 has an assembly support portion 13 for mounting and supporting the device support plate 10 movably in the horizontal direction, and an apparatus support plate supported by the assembly support portion 13. And a movement restricting mechanism 14 that is switchable between a restricting state in which the movement of 10 in the horizontal direction is restricted and a restriction releasing state in which the restriction is released.

組立用支持部13は、台車移動方向に沿う軸心周りに回転自在な組立用支持ローラ13aを台車移動方向及び台車横幅方向に複数並べて備え、この複数の組立用支持ローラ13aにて装置支持板10を載置支持自在に構成されている。そして、組立用支持部13は、台車横幅方向については組立用支持ローラ13aの回転により移動自在な状態で、台車移動方向については組立用支持ローラ13aとの摩擦により移動を規制した状態で載置支持している。   The assembly support unit 13 includes a plurality of assembly support rollers 13a that are rotatable around an axis along the carriage movement direction, arranged in the carriage movement direction and the carriage lateral width direction, and the plurality of assembly support rollers 13a are used to support the apparatus support plate. 10 is configured to be freely mounted and supported. The assembly support portion 13 is placed in a state where it can be moved by the rotation of the assembly support roller 13a in the horizontal direction of the carriage, and in a state where movement is restricted by friction with the assembly support roller 13a in the direction of movement of the carriage. I support it.

移動規制機構14は、組立用支持部13にて組立用載置位置に載置された装置支持板10の台車横幅方向の一方側に固定状態で設けられた固定規制部材15と、組立用支持部13にて組立用載置位置に載置された装置支持板10の台車横幅方向の他方側に台車横幅方向に沿う軸心周りに揺動自在な状態で設けられた揺動規制部材16と、を備えて構成されている。
そして、移動規制機構14は、組立用載置位置に位置する装置支持板10の台車横幅方向の一方側への移動を装置支持板10が固定規制部材15に接触することで規制し、組立用載置位置に位置する装置支持板10の台車横幅方向の他方側への移動を装置支持板10が揺動規制部材16に接触することで規制するように構成されている。
The movement restricting mechanism 14 includes a fixing restricting member 15 provided in a fixed state on one side in the cart lateral width direction of the apparatus support plate 10 placed at the assembling placement position by the assembling support portion 13, and an assembly support. A swing restricting member 16 provided on the other side in the cart lateral width direction of the apparatus support plate 10 placed at the assembly placement position in the portion 13 so as to be swingable about an axis along the cart lateral width direction; , And is configured.
Then, the movement restricting mechanism 14 restricts the movement of the apparatus support plate 10 located at the assembly mounting position to one side in the horizontal direction of the carriage by the apparatus support plate 10 coming into contact with the fixed restriction member 15. The movement of the apparatus support plate 10 located at the mounting position to the other side in the lateral width direction of the carriage is configured to be restricted by the apparatus support plate 10 coming into contact with the swing restriction member 16.

揺動規制部材16は、図7に実線で示すように、自然状態では規制用規律姿勢となっており、規制用上部16aが装置用載置位置に位置する装置支持板10と同じ高さに位置する規制位置に位置するように構成されている。また、図7に仮想線で示すように、揺動規制部材16は、規制用起立姿勢から揺動させて規制解除用転倒姿勢に姿勢変更させることで、規制用上部16aが装置用載置位置に位置する装置支持板10より下方に引退するように構成されている。   As shown by a solid line in FIG. 7, the swing restricting member 16 is in a restricting discipline posture in a natural state, and the upper portion 16a for restricting is at the same height as the device support plate 10 positioned at the device mounting position. It is comprised so that it may be located in the control position located. Further, as indicated by phantom lines in FIG. 7, the swing restricting member 16 is swung from the restricting standing posture to change the posture to the restriction releasing falling posture, so that the restricting upper portion 16a is moved to the apparatus mounting position. It is comprised so that it may withdraw | lower below the apparatus support plate 10 located in this.

移動台車8が検査箇所の検査台に隣接する箇所に移動するに伴って、揺動規制部材16の接触用下部16bが検査箇所に固定状態で設けられた接触体に接触することで、揺動規制部材16が規制用起立姿勢から規制解除用転倒姿勢に姿勢変更し、規制用上部16aが規制位置から規制解除位置に移動するようになっている。これにより検査箇所では、移動台車8から検査台に装置支持板ごと車両用昇降装置Lを移動させることができるようになっている。   As the movable carriage 8 moves to a position adjacent to the inspection table at the inspection location, the contact lower portion 16b of the swing restricting member 16 comes into contact with a contact body provided in a fixed state at the inspection location, thereby swinging. The restricting member 16 changes its posture from the restricting standing posture to the falling posture for releasing the restriction, and the upper portion 16a for restriction moves from the restricting position to the restricting release position. Thereby, in the inspection location, the vehicle lifting device L can be moved from the movable carriage 8 to the inspection stage together with the apparatus support plate.

図4及び図5に示すように、移動台車8には、床面上に設けられた案内レール20に案内される案内ローラ21が前後一対設けられている。この案内ローラ21は、移動車輪22を備えた台車本体19の台車横幅方向の一方側端部に連結支持されている。
案内レール20は、図2に示すように、組立箇所E1の組立ラインL1に沿って設けられている。そのため、案内ローラ21が案内レール20にて案内される状態で、牽引装置24(図2及び図3参照)により移動台車8を牽引して移動させることで、移動台車8を組立ラインL1に沿って移動させることや、作業者が手押し移動させることで、移動台車8を組立箇所E1から下流側の検査箇所に移動させることができるようになっている。このように、移動台車8は、組立対象の車両用昇降装置Lを支持した状態で組立ラインL1に沿って移動するように構成されている。
As shown in FIGS. 4 and 5, the movable carriage 8 is provided with a pair of front and rear guide rollers 21 guided by guide rails 20 provided on the floor surface. The guide roller 21 is connected and supported at one end portion of the carriage main body 19 having the moving wheels 22 in the carriage lateral width direction.
The guide rail 20 is provided along the assembly line L1 of the assembly location E1, as shown in FIG. Therefore, the movable carriage 8 is moved along the assembly line L1 by pulling and moving the movable carriage 8 by the towing device 24 (see FIGS. 2 and 3) while the guide roller 21 is guided by the guide rail 20. The movable carriage 8 can be moved from the assembly location E1 to the downstream inspection location by being moved by hand or manually pushed by the operator. Thus, the movable carriage 8 is configured to move along the assembly line L1 while supporting the vehicle lifting device L to be assembled.

案内レール20は、案内ローラ21が離脱自在な不連続箇所9を備えている。図4〜図6に示すように、案内レール20は縦断面形状がコの字状のレール部材30を、長手方向が組立ラインL1に沿う姿勢でかつコの字の開口が上向きとなる姿勢で、先端部30aが互いに間隔を空けた状態で床面に敷設されている。したがって、案内レール20は、移動台車8の案内ローラ21の車体横幅方向の移動を規制する状態で、移動台車8を組立ラインL1に沿って案内する。レール部材30の先端部30aは、先端側ほど幅広に形成されており、案内ローラ21をレール部材30の先端部30aに係合させ易くなっている。   The guide rail 20 includes a discontinuous portion 9 from which the guide roller 21 can be separated. As shown in FIGS. 4 to 6, the guide rail 20 is a rail member 30 having a U-shaped longitudinal cross-section in a posture in which the longitudinal direction is along the assembly line L <b> 1 and the U-shaped opening is upward. The distal end portion 30a is laid on the floor surface with a space therebetween. Therefore, the guide rail 20 guides the movable carriage 8 along the assembly line L1 in a state where the movement of the guide roller 21 of the movable carriage 8 in the lateral direction of the vehicle body is restricted. The distal end portion 30 a of the rail member 30 is formed wider toward the distal end side, so that the guide roller 21 can be easily engaged with the distal end portion 30 a of the rail member 30.

第1作業箇所E1a〜第4作業箇所E1dは、平面視で案内レール20の一方の横側に位置しており、平面視で案内レール20の他方の横側の床面には、返却用レール31が案内レール20に沿って敷設されている。つまり、案内レール20を挟んで第1作業箇所E1a〜第4作業箇所E1dとは反対側に、組立ラインL1に沿って返却用レール31が配設されている。返却用レール31は、組立箇所E1での作業及び検査箇所での作業が完了して、出荷箇所で車両用昇降装置Lが取り外されて空荷状態となった移動台車8を、組立ラインL1の台車移動方向で最上流に返却する際に移動台車8の移動を案内するために設けられている。   The first work location E1a to the fourth work location E1d are located on one side of the guide rail 20 in plan view, and the return rail is placed on the other side of the guide rail 20 in plan view. 31 is laid along the guide rail 20. That is, the return rail 31 is disposed along the assembly line L1 on the opposite side of the first work location E1a to the fourth work location E1d across the guide rail 20. The return rail 31 completes the work at the assembly location E1 and the work at the inspection location, and removes the moving carriage 8 from the shipping location where the vehicle lifting device L is removed and becomes an empty state in the assembly line L1. It is provided to guide the movement of the moving carriage 8 when returning to the most upstream in the carriage movement direction.

返却用レール31と案内レール20とは、組立ラインL1の台車列の移動方向で上流側の端部にて接続されており、返却用レール31に沿って当該端部まで移動させた移動台車8を、その案内ローラ21がレール部材30に係合した状態のまま旋回させて姿勢を変更できるようになっており、案内ローラ21を案内レール20に容易に係合させることができるようになっている。   The return rail 31 and the guide rail 20 are connected at the end on the upstream side in the movement direction of the carriage row of the assembly line L1, and the movable carriage 8 moved to the end along the return rail 31. The posture can be changed by turning the guide roller 21 while the guide roller 21 is engaged with the rail member 30, and the guide roller 21 can be easily engaged with the guide rail 20. Yes.

案内レール20における不連続箇所9では、牽引装置24にて移動される移動台車の案内ローラ21と案内レール20との係合が一時的に外れるが、不連続箇所9における台車移動方向での長さは、十分に短い長さとしているために、移動台車8が牽引装置24にて組立ラインL1に沿って移動されていれば、上流側のレール部材30から係合離脱した案内ローラ21は、このレール部材30から不連続箇所9に形成された間隔を隔てて下流側に隣接するレール部材30の先端部30aに再び係入させることができる。このように、不連続箇所9を設けても、移動台車8を台車移動方向に沿って移動させることができる。   At the discontinuous portion 9 in the guide rail 20, the engagement between the guide roller 21 and the guide rail 20 of the moving carriage moved by the traction device 24 is temporarily disengaged. Since the length is sufficiently short, if the moving carriage 8 is moved along the assembly line L1 by the traction device 24, the guide roller 21 that is disengaged from the rail member 30 on the upstream side is The rail member 30 can be re-engaged with the distal end portion 30a of the rail member 30 adjacent to the downstream side with an interval formed at the discontinuous portion 9 therebetween. Thus, even if the discontinuous portion 9 is provided, the movable carriage 8 can be moved along the carriage movement direction.

そして、案内レール20に不連続箇所9を備えさせてあるので、図6に示すように、不連続箇所9で係合解除された移動台車8を組立ラインL1から離脱させることが可能である。そのため、台車列を形成するある移動台車8上の組立途中の車両用昇降装置Lに何らかの不具合が発生した場合に、当該移動台車8を組立ラインL1から離脱させて、適切な処理をすることができる。
本実施形態では、第1作業箇所E1a、第2作業箇所E1b、第3作業箇所E1c、第4作業箇所E1dの夫々に対応して、不連続箇所9が案内レール20に備えられているので、第1工程〜第4工程のいずれの工程で組立不良が発生しても、当該組立不良が発生した移動台車8を組立ラインL1から迅速に離脱させることができる。
なお、移動台車8を台車列から離脱させる場合は、離脱対象の移動台車8の前後の移動台車8との連結を解除することになる。また、離脱対象の移動台車8が後述する被牽引台車8Mである場合は、台車移動方向で上流側の移動台車8を新たな被牽引台車8Mとして、作業者がその新たな被牽引台車8Mに牽引装置24のフック18を係合させることになる。
And since the discontinuous part 9 is provided in the guide rail 20, as shown in FIG. 6, it is possible to make the mobile trolley 8 disengaged at the discontinuous part 9 disengage from the assembly line L1. Therefore, in the event that some trouble occurs in the vehicle lifting device L during assembly on a certain mobile carriage 8 forming the carriage train, the mobile carriage 8 can be detached from the assembly line L1 and subjected to appropriate processing. it can.
In the present embodiment, the discontinuous portion 9 is provided in the guide rail 20 corresponding to each of the first work location E1a, the second work location E1b, the third work location E1c, and the fourth work location E1d. Even if an assembly failure occurs in any of the first to fourth steps, the movable carriage 8 in which the assembly failure has occurred can be quickly detached from the assembly line L1.
When the moving carriage 8 is detached from the carriage row, the connection with the moving carriage 8 before and after the moving carriage 8 to be removed is released. In addition, when the moving cart 8 to be detached is a towed cart 8M, which will be described later, the upstream moving cart 8 in the cart moving direction is set as a new towed cart 8M, and the operator changes to the new towed cart 8M. The hook 18 of the traction device 24 is engaged.

牽引終了位置Peまで移動した被牽引台車8Mに係合されているフック18を牽引開始位置Psまで戻すべく、台車列の移動方向と反対方向にフック18を移動させて次の被牽引台車8Mにフック18を係合させる際は、作業者は巻取装置17の作動を停止させてワイヤ23を繰り出し自在な状態に切り換えてから、フック18を牽引開始位置Psまで復帰移動させる。   In order to return the hook 18 engaged with the towed carriage 8M that has moved to the towing end position Pe to the towing start position Ps, the hook 18 is moved in the direction opposite to the moving direction of the carriage row to move to the next towed truck 8M. When engaging the hook 18, the operator stops the operation of the winding device 17 and switches the wire 23 to a state in which the wire 23 can be fed out, and then returns the hook 18 to the pulling start position Ps.

このように、移動装置としての牽引装置24が、台車移動方向に沿って移動自在に設けられた係合部としてのフック18と、このフック18を移動させる移動駆動部としてのワイヤ23及び巻取装置17と、を備えている。そして、ワイヤ23を連結した牽引対象の被牽引台車8Mを牽引開始位置Psから牽引終了位置Peまで牽引装置24にて牽引することで、牽引対象の移動台車8より台車移動方向で前方側(下流側)に位置する移動台車8は押し操作され、牽引対象の被牽引台車8Mより台車移動方向で後方側(上流側)に位置する移動台車8は引き操作されて、台車列を形成する複数台の移動台車8の全てを移動させるようになっている。   As described above, the traction device 24 as the moving device includes the hook 18 as the engaging portion provided movably along the moving direction of the carriage, the wire 23 as the moving drive unit for moving the hook 18 and the winding. And a device 17. Then, by pulling the towed truck 8M to which the wire 23 is connected from the towing start position Ps to the towing end position Pe by the towing device 24, the front side (downstream) of the towed moving carriage 8 in the carriage moving direction. The movable carriage 8 located on the side) is pushed, and the movable carriage 8 located on the rear side (upstream side) in the carriage movement direction from the towed carriage 8M to be towed is pulled to form a plurality of carriages. All of the movable carriages 8 are moved.

また、組立ラインL1上に、フック18を移動台車8における引っ掛け用部材25に係合させる牽引開始位置Psと、台車列を形成する状態の複数の移動台車8のうち牽引開始位置Psでフック18が係合した移動台車8を被牽引台車8Mとしてこの被牽引台車8Mの下流側に隣接する移動台車8よりさらに下流側の位置であってフック18を被牽引台車8Mにおける引っ掛け用部材25から離脱させる位置としての牽引終了位置Peとが設定されている。   Also, on the assembly line L1, the hook 18 is engaged at the traction start position Ps where the hook 18 is engaged with the hooking member 25 of the movable carriage 8, and at the traction start position Ps among the plurality of movable carriages 8 in a state where a carriage row is formed. The movable carriage 8 engaged with the traction carriage 8M is taken as a towed carriage 8M, and the hook 18 is detached from the hooking member 25 in the towed carriage 8M at a position further downstream than the moving carriage 8 adjacent to the downstream side of the towed carriage 8M. A pulling end position Pe as a position to be moved is set.

尚、連結棒27を転倒させて連結用係合部26を引っ掛け用部材25に係合させたときの連結棒27の姿勢を水平姿勢としたが、上述のように牽引装置24にて牽引したときに連結用係合部26が引っ掛け用部材25から外れないのであれば、連結用係合部26を引っ掛け用部材25に係合させたときの連結棒27の姿勢を後方側ほど上方又は下方に位置する傾斜姿勢としてもよい。   In addition, although the connecting rod 27 is turned over and the connecting engagement portion 26 is engaged with the hooking member 25, the posture of the connecting rod 27 is set to the horizontal posture, but it is pulled by the pulling device 24 as described above. If the connecting engagement portion 26 does not come off from the hooking member 25, the posture of the connecting rod 27 when the connecting engaging portion 26 is engaged with the hooking member 25 is increased upward or downward toward the rear side. It is good also as an inclination posture located in.

図2に示すように、組立箇所E1では、移動台車8に載置支持された装置支持板10に基枠1を固定し、その基枠1に、油圧モータ等の油圧機器、平行四連リンク機構、昇降アーム6、昇降枠3、載置体2等を順次取り付けて車両用昇降装置Lを組み立てており、移動台車8が組立ラインL1に沿って移動する間に移動台車8上に車両用昇降装置Lが組み立てられる。
そして、移動台車8上に車両用昇降装置Lが組み立てられて、牽引終了位置Peとしての組立ラインL1の下流端まで移動した移動台車8は、連結棒27を起立させて上流側に隣接する移動台車8との連結を解除して、作業者の押引操作により一台ずつ案内レール20に案内されて検査箇所まで移動させられる。つまり、牽引装置24は、台車列を形成する状態の複数の移動台車8のうち一台の被牽引台車8Mにおける引っ掛け用部材25にフック18を係合させた状態で、かつ、当該被牽引台車8Mより台車移動方向で下流側に移動台車8が連結された状態で、組立ラインL1における牽引開始位置Psからこの牽引開始位置Psより台車移動方向で下流側の牽引終了位置Peまで被牽引台車8Mを移動させるように構成されている。
As shown in FIG. 2, at the assembly location E <b> 1, the base frame 1 is fixed to the device support plate 10 placed and supported on the movable carriage 8, and hydraulic equipment such as a hydraulic motor, parallel quadruple link is attached to the base frame 1. The vehicle lifting device L is assembled by sequentially attaching the mechanism, the lifting arm 6, the lifting frame 3, the mounting body 2 and the like, and the vehicle is placed on the moving carriage 8 while the moving carriage 8 moves along the assembly line L1. The lifting device L is assembled.
Then, after the vehicle lifting device L is assembled on the movable carriage 8 and moved to the downstream end of the assembly line L1 as the pulling end position Pe, the movable carriage 8 moves up adjacent to the upstream side by raising the connecting rod 27. The connection with the carriage 8 is released, and the vehicle is guided to the guide rail 20 one by one by the operator's push-pull operation and moved to the inspection location. That is, the traction device 24 is in a state in which the hook 18 is engaged with the hooking member 25 in one towed carriage 8M among the plurality of moving carriages 8 in a state of forming a carriage row, and the towed carriage In a state where the moving carriage 8 is connected to the downstream side in the carriage movement direction from 8M, the towed carriage 8M from the towing start position Ps in the assembly line L1 to the towing end position Pe downstream in the carriage movement direction from the towing start position Ps. Is configured to move.

図7に示すように、移動台車8は、上流側に隣接する移動台車8との連結が解除されると、相互に連結されていた連結状態の設定間隔よりも互いに接近できることになる。そのため、作業者が移動台車8を押し引き操作する場面では、台車移動方向に隣接する移動台車8は連結棒27にて連結されておらず、このように連結棒27にて連結されていない台車移動方向に隣接する移動台車8の台車本体19同士が接触することを防止するために、移動台車8の前端及び後端に緩衝部材29が設けられている。   As shown in FIG. 7, when the mobile cart 8 is disconnected from the mobile cart 8 adjacent to the upstream side, the mobile carts 8 can be closer to each other than the set interval of the connected status. Therefore, in the scene where the operator pushes and pulls the movable carriage 8, the movable carriage 8 adjacent in the carriage movement direction is not connected by the connecting rod 27, and thus is not connected by the connecting rod 27. Buffer members 29 are provided at the front end and the rear end of the moving carriage 8 in order to prevent the carriage bodies 19 of the moving carriages 8 adjacent to each other in the moving direction from contacting each other.

そして、装置支持板10は、緩衝部材29を含む移動台車8の台車移動方向での長さより短い長さに形成されている。そのため、図7に示すような緩衝部材29同士が接触するように台車移動方向に隣接する2台の移動台車8が接触している状態でも、一方の移動台車8の組立用支持部13に載置支持された装置支持板10と他方の移動台車8の組立用支持部13に載置支持された装置支持板10との間に台車移動方向に作業者の手の厚みより広い隙間が形成されている。   The device support plate 10 is formed to have a length shorter than the length of the moving carriage 8 including the buffer member 29 in the carriage moving direction. For this reason, even when two moving carriages 8 adjacent to each other in the carriage moving direction are in contact with each other so that the buffer members 29 as shown in FIG. A gap wider than the thickness of the operator's hand is formed in the carriage moving direction between the apparatus support plate 10 that is placed and supported and the apparatus support plate 10 that is placed and supported on the assembly support portion 13 of the other movable carriage 8. ing.
