Description

本発明は、支柱と、支柱に昇降自在に設けられる昇降台と、昇降台に設けられ車体を載せる車体載せ台とからなる車体昇降装置に関する。   The present invention relates to a vehicle body lifting apparatus including a column, a lifting platform provided on the column so as to be movable up and down, and a vehicle body platform on which the vehicle body is mounted.

第１の組立ラインから第２の組立ラインへ車体を昇降させる車体昇降装置が各種提案されている（例えば、特許文献１（図１）参照。）。   Various vehicle lifting devices that raise and lower the vehicle body from the first assembly line to the second assembly line have been proposed (see, for example, Patent Document 1 (FIG. 1)).

図９に示すように、車体昇降装置２００は、支柱２０１に昇降自在に設ける昇降台２０２に車体２０３を載せて、車体２０３を第１のコンベア２０４の高さから第２のコンベア２０５の高さへ昇降させる。昇降台２０２が３段式の摺動フォークになっているため、車体２０３を第１のコンベア２０４から受取ることができ、車体２０３を第２のコンベア２０５へ移すことができる。   As shown in FIG. 9, the vehicle body elevating device 200 places the vehicle body 203 on an elevating platform 202 that can be moved up and down on a column 201, and moves the vehicle body 203 from the height of the first conveyor 204 to the height of the second conveyor 205. Move up and down. Since the lifting platform 202 is a three-stage sliding fork, the vehicle body 203 can be received from the first conveyor 204, and the vehicle body 203 can be transferred to the second conveyor 205.

しかし、車体２０３を昇降台２０２に載せて昇降させるとき、車体２０３の長さによっては車体２０３が昇降台２０２からはみ出す場合があるため、車体２０３の姿勢が昇降台２０２の上で不安定になる。
その対策として、昇降台２０２の更なる大型化が挙げられるが、コストアップに繋がる。 However, when the vehicle body 203 is moved up and down on the lifting platform 202, depending on the length of the vehicle body 203, the vehicle body 203 may protrude from the lifting platform 202, so the posture of the vehicle body 203 becomes unstable on the lifting platform 202. .
As a countermeasure for this, the size of the lifting platform 202 can be further increased, but this leads to an increase in cost.

そこで、車体の長さに拘わらず車体を安定した姿勢で昇降させることができる車体昇降装置が求められる。   Therefore, there is a need for a vehicle lifting device that can lift and lower the vehicle body in a stable posture regardless of the length of the vehicle body.

特開平６−２３９４４７号公報JP-A-6-239447

本発明は、車体の長さに拘わらず車体を安定した姿勢で昇降させることができる車体昇降装置を提供することを課題とする。   It is an object of the present invention to provide a vehicle lifting apparatus that can lift and lower a vehicle body in a stable posture regardless of the length of the vehicle body.

請求項１に係る発明は、基礎又は設備面から上方へ延ばされる支柱と、この支柱に昇降自在に設けられる昇降台と、この昇降台に設けられ車体を載せる車体載せ台とからなる車体昇降装置において、前記車体載せ台は、前記車体の左右両側面の下端部を、前記車体の車幅方向に挟んで前記車体を拘束する一対の押し機構を備えていることを特徴とする。   According to a first aspect of the present invention, there is provided a vehicle body elevating device comprising a column extending upward from the foundation or facility surface, a platform that is freely movable up and down on the column, and a vehicle platform that is mounted on the platform and mounts the vehicle body. The vehicle body mount includes a pair of pushing mechanisms for restraining the vehicle body with the lower ends of the left and right side surfaces of the vehicle body sandwiched in the vehicle width direction of the vehicle body.

請求項１に係る発明では、車体載せ台は、車体の左右両側面の下端部を、車体の車幅方向に挟んで車体を拘束する一対の押し機構を備える。
車体の左右両側面の下端部を、一対の押し機構で車幅方向に挟むため、車体の長さに拘わらず、車体を確実に拘束できる。一対の押し機構で車体を拘束するので、車体の姿勢が安定する。したがって、車体の長さに拘わらず車体を安定した姿勢で昇降させることができる車体昇降装置が提供される。 In the invention according to claim 1, the vehicle body mount is provided with a pair of push mechanisms for restraining the vehicle body by sandwiching the lower end portions of the left and right side surfaces of the vehicle body in the vehicle width direction of the vehicle body.
Since the lower end portions of the left and right side surfaces of the vehicle body are sandwiched in the vehicle width direction by the pair of push mechanisms, the vehicle body can be reliably restrained regardless of the length of the vehicle body. Since the vehicle body is restrained by the pair of push mechanisms, the posture of the vehicle body is stabilized. Therefore, there is provided a vehicle body lifting apparatus that can lift and lower the vehicle body in a stable posture regardless of the length of the vehicle body.

車体載せ台に、車体を拘束する一対の押し機構が備えられるため、車体の長さに応じて昇降台を大型化する必要がなく、車体昇降装置を小型化できる。
一対の押し機構は、車体の左右両側面の下端部を車体の車幅方向に挟むだけであり、構造が単純になるため、安価な機構となる。すなわち、車体昇降装置のコストアップが抑えられる。 Since the vehicle platform is provided with a pair of pushing mechanisms for restraining the vehicle body, it is not necessary to increase the size of the lifting platform according to the length of the vehicle body, and the vehicle lifting device can be downsized.
The pair of push mechanisms only need to sandwich the lower end portions of the left and right side surfaces of the vehicle body in the vehicle width direction of the vehicle body, and the structure becomes simple, so that the mechanism is inexpensive. That is, the cost increase of the vehicle body lifting device can be suppressed.

A driven pulley 89 of the power transmission mechanism 55 is attached to the left end of the input shaft 88, and a drive gear 91 is attached to the right side of the input shaft 88 in the longitudinal direction. The belt 98 wound around the driven pulley 89 is also wound around a drive pulley (FIG. 2, reference numeral 99) attached to the output shaft of the drive source (FIG. 2, reference numeral 54).

加えて、ギヤボックス５６の上端部に左上軸受９２と右上軸受９３とが設けられ、これら軸受９２、９３で中間軸９４が回転自在に支持される。この中間軸９４の長手方向中間部に、駆動ギヤ９１とラック８３に噛合う中間ギヤ９５が取付けられる。   In addition, an upper left bearing 92 and an upper right bearing 93 are provided at the upper end portion of the gear box 56, and the intermediate shaft 94 is rotatably supported by these bearings 92 and 93. An intermediate gear 95 that meshes with the drive gear 91 and the rack 83 is attached to the intermediate portion in the longitudinal direction of the intermediate shaft 94.

駆動源（図２、符号５４）を起動すると、動力伝達機構５５により駆動源の動力が入力軸８８に伝達される。動力が入力軸８８に入力されると、駆動ギヤ９１が回転するため、動力が駆動ギヤ９１から中間ギヤ９５、ラック８３の順に伝達される。
中間ギヤ９５の回転運動がラック８３の直線運動に変換され、中間台５２が下台５１に対して移動する。 When the drive source (FIG. 2, reference numeral 54) is activated, the power transmission mechanism 55 transmits the power of the drive source to the input shaft 88. When power is input to the input shaft 88, the drive gear 91 rotates, so that power is transmitted from the drive gear 91 to the intermediate gear 95 and the rack 83 in this order.

本体部７３の左部には、左スプロケット８１が回転自在に取付けられ、本体部７３の右部には、右スプロケット８２が回転自在に取付けられる。加えて、左スプロケット８１と上台５３の移動方向前端に設けるスプロケットとに左チェーン１０５が掛けられ、右スプロケット８２と下台５１の収納方向後端に設けるスプロケットとに右チェーン１０６が掛けられる。そのため、第１車体載せ台４０は、上台５３が中間台５２の移動速度の２倍の速度で同一方向に移動するように構成されている。   A left sprocket 81 is rotatably attached to the left part of the main body 73, and a right sprocket 82 is rotatably attached to the right part of the main body 73. In addition, the left chain 105 is hung on the left sprocket 81 and the sprocket provided at the front end of the upper base 53 in the moving direction, and the right chain 106 is hung on the right sprocket 82 and the sprocket provided at the rear end of the lower base 51 in the storing direction. Therefore, the first vehicle body mount 40 is configured such that the upper base 53 moves in the same direction at a speed twice that of the intermediate base 52.

上台５３に載せた車体（図１、符号１３）を拘束する押し機構の構成を図４に基づいて説明する。なお、図４では、車体の左右は、第１車体載せ台４０の収納方向に直交する方向を基準に定める。
図４に示すように、第１車体載せ台４０の上台５３は、車体１３の左サイドシル１０１の下端部１０２及び右サイドシル１０３の下端部１０４を、車体１３の車幅方向に挟んで車体１３を拘束する左押し機構１１０及び右押し機構１２０を、備える。なお、左押し機構１１０と右押し機構１２０の構造は同一である。 The structure of the pushing mechanism for restraining the vehicle body (FIG. 1, reference numeral 13) placed on the upper base 53 will be described with reference to FIG. In FIG. 4, the left and right sides of the vehicle body are determined based on a direction orthogonal to the storage direction of the first vehicle body mount 40.
As shown in FIG. 4, the upper base 53 of the first vehicle body mount 40 holds the vehicle body 13 with the lower end portion 102 of the left side sill 101 and the lower end portion 104 of the right side sill 103 of the vehicle body 13 sandwiched in the vehicle width direction of the vehicle body 13. A left push mechanism 110 and a right push mechanism 120 for restraining are provided. Note that the left push mechanism 110 and the right push mechanism 120 have the same structure.

一対の押し機構１１０、１２０は、車体１３の左サイドシル１０１の下端部１０２及び右サイドシル１０３の下端部１０４を車体１３の車幅方向に挟むだけであり、構造が単純になるため、安価な機構となる。すなわち、車体昇降装置（図２、符号２０）のコストアップが抑えられる。   The pair of pushing mechanisms 110 and 120 is simply a structure in which the lower end portion 102 of the left side sill 101 and the lower end portion 104 of the right side sill 103 of the vehicle body 13 are sandwiched in the vehicle width direction of the vehicle body 13. It becomes. That is, the cost increase of the vehicle body lifting device (FIG. 2, reference numeral 20) can be suppressed.

上台５３の上面に、車体１３の底部１２１に設けた左凸部１２２と右凸部１２３が載っている。
図２において、上台５３の幅をＷとすると、左押し機構１１０と右押し機構１２０の設置位置は、Ｗ／２となる。つまり、左押し機構１１０と右押し機構１２０は、上台５３の幅方向中心に配置される。 A left convex portion 122 and a right convex portion 123 provided on the bottom portion 121 of the vehicle body 13 are placed on the upper surface of the upper base 53.
In FIG. 2, when the width of the upper base 53 is W, the installation positions of the left push mechanism 110 and the right push mechanism 120 are W / 2. That is, the left push mechanism 110 and the right push mechanism 120 are arranged at the center of the upper base 53 in the width direction.

左押し機構１１０の構成を図５に基づいて説明する。
図５に示すように、左押し機構１１０は、上台５３の上面に取付部材１２４で取付けられるシリンダ１２５と、このシリンダ１２５のピストンロッド１２６に止め部材１２７を介して連結され上台５３の上面に設けたレール１２８で摺動自在に支持されるスライド部材１２９と、このスライド部材１２９の右面上端に止められスライド部材１２９の前進方向に延びる左ピン部材１３１とからなる。この左ピン部材１３１の先端で、サイドシル（図４、符号１０１）の下端部（図４、符号１０２）を押す。 The configuration of the left push mechanism 110 will be described with reference to FIG.
As shown in FIG. 5, the left push mechanism 110 is provided on the upper surface of the upper base 53, which is connected to the cylinder 125 attached to the upper surface of the upper base 53 by the mounting member 124, and the piston rod 126 of the cylinder 125 via the stopper member 127. The slide member 129 is slidably supported by the rail 128, and the left pin member 131 is stopped at the upper right end of the slide member 129 and extends in the forward direction of the slide member 129. At the tip of the left pin member 131, the lower end (FIG. 4, reference numeral 102) of the side sill (FIG. 4, reference numeral 101) is pushed.

以上に述べた第１車体昇降装置２０の作用を次に述べる。

As shown in (b), the first vehicle body mount 40 is raised toward the bottom of the vehicle body 13 as shown by an arrow (9).

（ｃ）に示すように、左押し機構１１０のシリンダ１２５で左ピン部材１３１を、矢印（１０）のように左サイドシル１０１に向けて押出す。また、右押し機構１２０のシリンダ１３５で右ピン部材１３６を、矢印（１１）のように右サイドシル１０３に向けて押出す。
（ｄ）に示すように、左ピン部材１３１で左サイドシル１０１の下端部１０２が押される。 As shown in (c), the left pin member 131 is pushed out toward the left side sill 101 as shown by an arrow (10) by the cylinder 125 of the left push mechanism 110. Further, the right pin member 136 is pushed out toward the right side sill 103 as indicated by an arrow (11) by the cylinder 135 of the right push mechanism 120.
As shown in (d), the lower end 102 of the left side sill 101 is pushed by the left pin member 131.

（ｃ）において、車体１３の左サイドシル１０１の下端部１０２及び右サイドシル１０３の下端部１０４を、左右一対の押し機構１１０、１２０で車幅方向に挟むため、車体１３の長さに拘わらず、車体１３を確実に拘束できる。一対の押し機構１１０、１２０で車体１３を拘束するので、車体１３の姿勢が安定する。したがって、車体１３の長さに拘わらず車体１３を安定した姿勢で昇降させることができる車体昇降装置２０が提供される。   In (c), the lower end portion 102 of the left side sill 101 and the lower end portion 104 of the right side sill 103 of the vehicle body 13 are sandwiched in the vehicle width direction by the pair of left and right push mechanisms 110, 120. The vehicle body 13 can be reliably restrained. Since the vehicle body 13 is restrained by the pair of push mechanisms 110 and 120, the posture of the vehicle body 13 is stabilized.

As shown in FIG. 7A, the vehicle body 13 is positioned by the positioning member 137 on the first pallet 36 and rests on the support member 133 on the first pallet 36. Further, an upper base 53 is waiting below the vehicle body 13. At this time, the center of gravity 138 of the vehicle body 13 and the center of the width of the upper base 53 (see FIG. 2) coincide, and the distance from the center of the positioning member 137 to the center of gravity 138 is L1.

（ｂ）に示すように、車体１３を昇降させるとき、車体１３の重心１３８が、上台５３の幅中心に配置された左ピン部材１３１の中心と一致する。そのため、車体１３を安定した姿勢で昇降させることができる。   As shown in (b), when the vehicle body 13 is raised and lowered, the center of gravity 138 of the vehicle body 13 coincides with the center of the left pin member 131 disposed at the center of the width of the upper base 53. Therefore, the vehicle body 13 can be lifted and lowered in a stable posture.

次に、車体１３よりも大型の車体１３９（大型車両）の重心と左ピン部材１３１の位置関係を図８に基づいて説明する。
