Description

本発明は、台車を停車させるべき目標まで案内し、その場所に位置決めできる停車支援装置に関する。 The present invention is to guide to the target should be stopped the truck, on the car support device stops that can be positioned in its place.

図１０に示す台車２は、オペレータがハンドル１７を矢印Ｌで指した方向へ繰り返し倒すと、フォーク４が上昇するよう構成された油圧ジャッキ１８を備える。また、オペレータが図に表れていないレバーを操作するとフォーク４が下降する。フォーク４には、複数のローラ１９を上面に設けた荷台１が取付けられ、フォーク４と共に荷台１が昇降する。また、台車２はオペレータの手押しによって走行し、オペレータがハンドル１７を旋回すると、これに従って操舵輪１６も同方向へ旋回する。符号２０は、荷台１の前方へ突出したフック付きピンを指している。 The cart 2 shown in FIG. 10 includes a hydraulic jack 18 configured to raise the fork 4 when the operator repeatedly tilts the handle 17 in the direction indicated by the arrow L. Further, when the operator operates a lever not shown in the drawing, the fork 4 is lowered. A loading platform 1 having a plurality of rollers 19 provided on the upper surface is attached to the fork 4, and the loading platform 1 moves up and down together with the fork 4. Further, the carriage 2 travels by being pushed by the operator, and when the operator turns the handle 17, the steered wheels 16 also turn in the same direction. Reference numeral 20 indicates a pin with a hook protruding forward of the loading platform 1.

図１１に示すように、台車２に載せた蓄電池２１を無人搬送車両１４の電池収納部１５へ移載する場合、オペレータは、台車２のフック付きピン２０と、無人搬送車両１４のフレームの側面に形成した挿入孔２２とを正確に合せながら、台車２を無人搬送車両１４に接近させる。そして、フック付きピン２０が挿入孔２２へ進入したところで、オペレータが荷台１を少し下降させれば、フック付きピン２０を挿入孔２２の口縁に掛止めできる。これにより、台車２を無人搬送車両１４に位置決めできると同時に、荷台１の上面と電池収納部１５の床面との高さを一致させることができる。電池収納部１５の上面には、荷台１と同様に複数のローラ１９が設けられており、オペレータが蓄電池２１を台車２の前方へ手で押出すと、蓄電池２１は荷台１から電池収納部１５の奥へ滑動する。 As shown in FIG. 11, when the storage battery 21 placed on the carriage 2 is transferred to the battery storage unit 15 of the automated guided vehicle 14, the operator can connect the hooked pin 20 of the automated carriage 2 and the side surface of the frame of the automated guided vehicle 14. The carriage 2 is brought close to the automatic guided vehicle 14 while accurately aligning with the insertion hole 22 formed in the above. Then, when the hooked pin 20 enters the insertion hole 22 and the operator lowers the loading platform 1 slightly, the hooked pin 20 can be hooked on the edge of the insertion hole 22. Thereby, the carriage 2 can be positioned on the automatic guided vehicle 14, and at the same time, the height of the upper surface of the loading platform 1 and the floor surface of the battery storage unit 15 can be matched. A plurality of rollers 19 are provided on the upper surface of the battery storage unit 15 in the same manner as the loading platform 1. When the operator pushes the storage battery 21 by hand to the front of the carriage 2, the storage battery 21 is moved from the loading platform 1 to the battery storage unit 15. Slide to the back.

フォーク４、フック付きピン２０、及び挿入孔２２は、それぞれ図１１に１つずつ表れているが、これらの要素は、台車２の車幅方向に隔たる位置で対を成すように、２つずつ設けられている。この他、台車を車両に位置決めする技術は下記の特許文献に開示されている。
特開２００５−９６５０３号公報 The fork 4, the hooked pin 20, and the insertion hole 22 appear one by one in FIG. 11, but these two elements are paired at positions separated in the vehicle width direction of the carriage 2. It is provided one by one. In addition, techniques for positioning the carriage on the vehicle are disclosed in the following patent documents.
JP 2005-96503 A

しかしながら、フック付きピン２０を挿入孔２２へ真っ直ぐに進入できるように、オペレータが台車２を運転するのは難しい。また。フック付きピン２０と挿入孔２２との高さを一致させるために、オペレータが荷台１の昇降を何度か繰り返すこともある。このため、オペレータが作業に手間取るという問題がある。また、蓄電池２１の大型化に伴なって、フック付きピン２０及び挿入孔２２を確認しようとするオペレータの視線が蓄電池２１によって遮られることがある。この場合は上記の問題が顕著になる。 However, it is difficult for the operator to drive the carriage 2 so that the pin 20 with the hook can enter the insertion hole 22 straightly. Also. To match the height of the hook with the pin 20 and the insertion hole 22, sometimes the operator repeated several times to lift the loading platform 1. For this reason, there is a problem that an operator takes time for work. Further, as the storage battery 21 increases in size, the storage battery 21 may block the line of sight of an operator who wants to check the hooked pin 20 and the insertion hole 22. In this case, the above problem becomes remarkable.

そこで、本発明の目的は、台車を容易に且つ正確に位置決めできる停車支援装置を提供することにある。 Therefore, an object of the present invention is to provide a stop support device that can easily and accurately position a carriage.

本発明は、荷台を昇降自在に支持した台車の前後方向の位置、及び前記台車の車幅方向の位置を、前記台車の前方の目標に合致させる停車支援装置に係るものであって、互いに前記前後方向に隔たり、前記台車から前記車幅方向へそれぞれ突出した複数のローラと、前記荷台に固定され前記ローラを回転自在に軸支する支持体と、前記支持体に固定され前記複数のローラの下方へそれぞれ突出した複数のピンと、前記複数のローラに対向する案内面、及び前記案内面の下方に設けられたストッパに複数の嵌入孔を形成した案内部材と、前記台車の走行する前途を横切り前記台車が突き当たる停止部材とを備え、前記台車を前記停止部材へ向けて走行させる行程で、前記複数のローラが前記案内部材の案内面にそれぞれ転がり接触することにより、前記台車が前記案内面に沿う姿勢となり、前記台車が前記停止部材に突き当たった状態で、前記荷台と共に下降する前記支持体が前記案内部材のストッパに受け止められ、前記複数のピンが、前記ストッパの複数の嵌入孔にそれぞれ嵌入することを特徴とする。 The present invention relates to a stopping support device for matching the position in the front-rear direction of the carriage that supports the loading platform so as to be movable up and down, and the position in the vehicle width direction of the carriage to a target in front of the carriage. A plurality of rollers spaced in the front-rear direction and projecting from the carriage in the vehicle width direction, a support fixed to the loading platform and rotatably supporting the rollers, and fixed to the support and A plurality of pins each projecting downward, a guide surface facing the plurality of rollers, a guide member having a plurality of insertion holes formed in a stopper provided below the guide surface, and the road traveled by the carriage and a stop member to which the carriage abuts, in stroke for running toward the carriage to the stop member, that said plurality of rollers are in rolling contact respectively with the guide surface of the guide member Becomes a posture in which the carriage is along the guide surface, in a state in which the carriage is abutted against the said stop member, said support is received in the stopper of the guide member descends together with the loading platform, said plurality of pins, said stopper The plurality of insertion holes are respectively inserted into the plurality of insertion holes.

本発明に係る停車支援装置によれば、台車を手押しするオペレータが、台車を停止部材へ向けて走行させる行程で、台車を案内部材に幅寄せすると、荷台から突出した複数のローラのうち最も台車の前にあるローラが案内部材の案内面に転がり接触する。更に、オペレータが台車を案内部材に幅寄せしながら、案内面に沿って走行させれば、複数のローラの全てのローラが案内面に同時に転がり接触し、台車の全体が案内面に沿った姿勢となる。これにより、台車の前方の目標に台車の車幅方向の位置が合致する。更にオペレータが台車を走行させ続ければ、台車は停止部材に突き当る。この時点で、台車は停止し上記の目標に台車の前後方向の位置が合致する。 According to the stop assist device of the present invention, when the operator pushing the cart moves the cart toward the stop member in the process of driving the cart toward the stop member, the cart is the most among the plurality of rollers protruding from the loading platform. The roller in front of the roller rolls into contact with the guide surface of the guide member. Furthermore, if the operator travels along the guide surface while bringing the cart closer to the guide member, all the rollers of the plurality of rollers are in rolling contact with the guide surface at the same time, and the entire cart is positioned along the guide surface. It becomes. As a result, the position of the carriage in the vehicle width direction matches the target ahead of the carriage. If the operator continues to drive the carriage, the carriage will hit the stop member. At this point, the carriage stops and the position of the carriage in the front-rear direction matches the above target.

以上のように、本発明に係る停車支援装置によれば、台車の車幅方向の位置、及び台車の前後方向の位置を目標に合致させる作業を、オペレータの勘に頼ることなく迅速にしかも確実に行うことができる。 As described above, according to the stop assist device according to the present invention, the operation of matching the position of the carriage in the vehicle width direction and the position of the carriage in the front-rear direction to the target can be performed quickly and reliably without depending on the operator's intuition. Can be done.

続いて、オペレータが荷台を下降させれば、荷台と共に複数のピンが下降して、停止部材の複数の嵌入孔にそれぞれ嵌入する。これにより台車を案内部材に固定することができる。しかも、案内部材は、荷台が下降できる高さを規定するストッパに、複数の嵌入孔を形成しているので、例えば荷台の上面に載せた荷物を台車から荷受け場所へ移載する場合、荷台の上面が荷受け場所の床面と一致する高さまで荷台が下降したところで、荷台をストッパで受止めることができる。 Subsequently, when the operator lowers the loading platform, the plurality of pins are lowered together with the loading platform and are respectively fitted into the plurality of insertion holes of the stop member. Thereby, the carriage can be fixed to the guide member. In addition, since the guide member has a plurality of insertion holes formed in the stopper that defines the height at which the loading platform can be lowered, for example, when transferring a load placed on the upper surface of the loading platform from the carriage to the receiving place, When the loading platform is lowered to a height where the upper surface coincides with the floor surface of the loading location, the loading platform can be received by a stopper.

従って、本発明に係る停車支援装置によれば、荷台の高さを調整するために、オペレータが荷台の昇降を繰り返すという手間を省くことができる。 Therefore, according to the stop assistance device according to the present invention, it is possible to save the operator from repeatedly raising and lowering the loading platform in order to adjust the height of the loading platform.

図１，２は、荷台１を昇降自在に支持した台車２の位置を、台車２の前方の目標に合致させる停車支援装置３を示している。台車２の位置とは、矢印Ｌで指した前後方向、及び矢印Ｗで指した車幅方向にて決まる平面上の位置と、フォーク４と共に昇降する荷台１の高さとを意味する。また、従来の技術として既に述べた要素については、以下でも同じ符号を用いる。 1 and 2 show a stop support device 3 that matches the position of a carriage 2 that supports the loading platform 1 so as to be movable up and down with a target in front of the carriage 2. The position of the carriage 2 means the position on the plane determined by the front-rear direction indicated by the arrow L and the vehicle width direction indicated by the arrow W, and the height of the loading platform 1 that moves up and down together with the fork 4. In addition, the same reference numerals are used for elements already described as conventional techniques.

停車支援装置３は、互いに前後方向に隔たり台車２から車幅方向の片側へ突出した２個のローラ５，６と、２個のローラ５，６の下方へそれぞれ突出した２本のテーパピン７と、後述の案内部材８及び停止部材９とを備える。 The stop assistance device 3 includes two rollers 5 and 6 projecting from the carriage 2 to one side in the vehicle width direction and two taper pins 7 projecting downward from the two rollers 5 and 6, respectively. A guide member 8 and a stop member 9 described later are provided.

図３，４に示すように、ローラ５は、上下に重なり合う２枚の三角鋼板から成る支持体１０の間に回転自在に軸支されている。ローラ６についても同様である。支持体１０は荷台１の側面に固定されている。テーパピン７は、支持体１０の下面に固定され、支持体１０を介して荷台１に接続されている。テーパピン７は必ずしもローラ５，６と同じ支持体１０に設ける必要はない。例えば、ローラ５，６を支持する支持体１０を台車２の適所に固定し、荷台１に接続した別の支持体にテーパピン７を固定しても良い。 As shown in FIGS. 3 and 4, the roller 5 is rotatably supported between a support body 10 made of two triangular steel plates that are vertically overlapped. The same applies to the roller 6. The support 10 is fixed to the side surface of the loading platform 1. The taper pin 7 is fixed to the lower surface of the support 10 and connected to the loading platform 1 via the support 10. The taper pin 7 is not necessarily provided on the same support 10 as the rollers 5 and 6. For example, the support body 10 that supports the rollers 5 and 6 may be fixed at an appropriate position of the carriage 2, and the taper pin 7 may be fixed to another support body connected to the loading platform 1.

案内部材８は、図１，４に示すように、２個のローラ５，６に対向する案内面１１及び２つの嵌入孔１２を有する。案内面１１は、個々のローラ５，６が転がり接触できるものであれば良く、例えば建物の壁等を利用しても良い。嵌入孔１２は、案内面１１の下方に水平姿勢で固定された鋼板からなるストッパ１３を貫通している。ストッパ１３として長尺な形状を図示しているが、案内面１１から突出する２つの小片に、２つの嵌入孔１２をそれぞれ１つずつ形成しても良い。嵌入孔１２の内径は、テーパピン７がその上方から出没自在に嵌入できるよう設定されている。 As shown in FIGS. 1 and 4, the guide member 8 has a guide surface 11 and two insertion holes 12 facing the two rollers 5 and 6. The guide surface 11 may be anything as long as the individual rollers 5 and 6 can be brought into rolling contact with each other. For example, a wall of a building may be used. The insertion hole 12 passes through a stopper 13 made of a steel plate fixed below the guide surface 11 in a horizontal posture. Although a long shape is illustrated as the stopper 13, two insertion holes 12 may be formed in each of two small pieces protruding from the guide surface 11. The inner diameter of the insertion hole 12 is set so that the taper pin 7 can be inserted and retracted from above.

停止部材９は、荷台１の前端、又はフォーク４の先端、その他、台車の適所に突き当たることにより、台車２を所望の位置に停止させられるものであれば良い。例えば、荷台１が走行する前途を横切る壁面、又は車輪止め等を停止部材９として適用しても良い。 The stop member 9 may be any member that can stop the carriage 2 at a desired position by hitting the front end of the loading platform 1 or the tip of the fork 4 or any other appropriate position of the carriage. For example, a wall surface that crosses the road ahead of the loading platform 1 or a wheel stopper may be applied as the stop member 9.

図５に示す無人搬送車両１４に対して台車２を位置決めする例を説明する。この位置決めは、無人搬送車両１４の電池収納部１５を目標とし、電池収納部１５に台車２の荷台１を縦列させ、両者を近接させ、且つ荷台１の上面の高さを電池収納部１５の床面に一致させることである。また、本実施例では、案内部材８の案内面１１として、無人搬送車両１４の荷台のフレームの側面を利用し、停止部材９として、無人搬送車両１４の電池収納部１５の縁部を利用する。 The example which positions the trolley | bogie 2 with respect to the automatic guided vehicle 14 shown in FIG. 5 is demonstrated. This positioning is aimed at the battery storage unit 15 of the automatic guided vehicle 14, the loading platform 1 of the carriage 2 is arranged in a row in the battery storage unit 15, the two are brought close to each other, and the height of the upper surface of the loading platform 1 is set to To match the floor. In this embodiment, the side surface of the loading frame of the automatic guided vehicle 14 is used as the guide surface 11 of the guide member 8, and the edge of the battery storage unit 15 of the automatic guided vehicle 14 is used as the stop member 9. .

先ず、台車２を手押しするオペレータが荷台１を上昇させる。この作業は、オペレータが一見して、荷台１の上面の高さが電池収納部１５の床面よりも高くなったことが分かれば良い。 First, an operator pushing the cart 2 raises the loading platform 1. This operation may be performed if the operator sees that the height of the upper surface of the loading platform 1 is higher than the floor surface of the battery storage unit 15.

続いて、図６に示すように、オペレータが、台車２を停止部材９へ向けて走行させる行程で、台車２を案内部材８に幅寄せすることにより、前のローラ５を案内部材８の案内面１１に転がり接触させる。台車２はその後部に操舵輪１６があるので、オペレータが台車２を案内面１１に沿って走行させながら、ハンドル１７を図中で反時計回りに旋回させれば、図７に示すように、台車２の後部が案内面１１に接近し、後のローラ６も案内面１１に転がり接触する。 Subsequently, as shown in FIG. 6, the operator moves the carriage 2 toward the guide member 8 in the process of causing the carriage 2 to travel toward the stop member 9, whereby the previous roller 5 is guided by the guide member 8. Roll contact with surface 11. Since the carriage 2 has the steering wheel 16 at the rear part thereof, if the operator turns the handle 17 counterclockwise in the drawing while traveling the carriage 2 along the guide surface 11, as shown in FIG. The rear part of the carriage 2 approaches the guide surface 11, and the rear roller 6 also rolls into contact with the guide surface 11.

２個のローラ５，６が案内面１１に同時に接触するに至ると、台車２の全体が案内面１１に沿った姿勢となる。これにより、台車２の荷台１を電池収納部１５に縦列させ、電池収納部１５に対して荷台１の車幅方向の位置を合致させることができる。この状態を維持しながら、オペレータが更に台車２を案内面１１に沿って走行させれば、荷台１の前端が停止部材９に突き当り台車２が停止する。これにより、台車２の荷台１を電池収納部１５縁部に近接させ、電池収納部１５に対して荷台１の前後方向の位置を合致させることができる。 When the two rollers 5 and 6 come into contact with the guide surface 11 at the same time, the entire carriage 2 takes a posture along the guide surface 11. Thereby, the loading platform 1 of the cart 2 can be aligned in the battery storage unit 15, and the position of the loading platform 1 in the vehicle width direction can be matched with the battery storage unit 15. If the operator further moves the carriage 2 along the guide surface 11 while maintaining this state, the front end of the loading platform 1 hits the stop member 9 and the carriage 2 stops. Thereby, the loading platform 1 of the cart 2 can be brought close to the edge of the battery housing portion 15, and the position of the loading platform 1 in the front-rear direction can be matched with the battery housing portion 15.

この状態で、２本のテーパピン７が、それぞれ２つの嵌入孔１２の真上に位置するので、オペレータが荷台１を下降させれば、図４に示すように、荷台１と共に２本のテーパピン７が下降して、ストッパ１３の２つの嵌入孔１２にそれぞれ嵌入する。これにより、台車２を案内部材８に固定することができる。 In this state, since the two taper pins 7 are respectively located immediately above the two insertion holes 12, if the operator lowers the loading platform 1, the two taper pins 7 together with the loading platform 1 are provided as shown in FIG. Descends and fits into the two insertion holes 12 of the stopper 13 respectively. Thereby, the cart 2 can be fixed to the guide member 8.

以上のように、停車支援装置３によれば、荷台１の車幅方向の位置、及び荷台１の前後方向の位置を目標に合致させる作業を迅速に、しかも確実に行うことができる。このため、蓄電池２１の大型化に伴なってオペレータが台車２の前方を確認しようとする視線が遮られることがあっても、オペレータの勘に頼ることなく、上記の作業を行えるという利点がある。 As described above, according to the stop assistance device 3, the operation of matching the position of the loading platform 1 in the vehicle width direction and the position of the loading platform 1 in the front-rear direction can be performed quickly and reliably. For this reason, there is an advantage that the above operation can be performed without relying on the intuition of the operator even if the line of sight of the operator confirming the front of the carriage 2 is obstructed as the storage battery 21 is enlarged. .

また、荷台１が下降することにより荷台１の上面の高さが電池収納部１５の床面に一致した時点で、支持体１０の下面がストッパ１３に受止められる。支持体１０の下面がストッパ１３に受止められた後、オペレータが荷台１を下降させる操作をしなければ、荷台１に載せられた蓄電池の荷重を油圧ジャッキ１８が受止めるので、ストッパ１３が蓄電池の荷重を直に受けることはない。従って、停車支援装置３によれば、荷台１の高さを調整するために、オペレータが荷台１の昇降を繰り返すという手間を省くことができる。 Further, the lower surface of the support 10 is received by the stopper 13 when the height of the upper surface of the loading platform 1 coincides with the floor surface of the battery storage unit 15 by the lowering of the loading platform 1. After the lower surface of the support 10 is received by the stopper 13, if the operator does not perform an operation to lower the loading platform 1, the hydraulic jack 18 receives the load of the storage battery placed on the loading platform 1. The load of is not received directly. Therefore, according to the stop assistance device 3, in order to adjust the height of the loading platform 1, it is possible to save time and labor for the operator to repeatedly raise and lower the loading platform 1.

尚、本発明は、その趣旨を逸脱しない範囲で当業者の知識に基づいて種々なる改良、修正、又は変形を加えた態様で実施できる。例えば、台車２の車幅方向の両側からローラ５，６を突出し、これらの下方へテーパピン７をそれぞれ突出しても良い。この場合、図５に示す無人搬送車両１４の案内部材８の他に、案内部材８の反対側に位置するフレームを案内部材８'として利用できる。 It should be noted that the present invention can be implemented in variously modified, modified, or modified forms based on the knowledge of those skilled in the art without departing from the spirit of the present invention. For example, the rollers 5 and 6 may be protruded from both sides of the carriage 2 in the vehicle width direction, and the taper pins 7 may be protruded below these rollers. In this case, in addition to the guide member 8 of the automatic guided vehicle 14 shown in FIG. 5, a frame located on the opposite side of the guide member 8 can be used as the guide member 8 ′.

本発明は、あらゆる荷物を台車に載せて搬送し、この台車から荷物を荷置き場所、又はコンベヤ等の搬送装置へ移載する場合に、台車を所望の位置に停車させるのに有益な技術である。 The present invention is a technique useful for stopping a carriage at a desired position when all kinds of luggage are transported on a carriage, and the luggage is transferred from the carriage to a loading place or a conveying device such as a conveyor. is there.
