Description

本発明は工場等で製品等が収納された搬送物を所定の位置から他の位置まで搬送する搬送台車に係るもので、特に高い位置の搬送物を搬入し、低い位置へ搬出する搬送台車に好適である。   The present invention relates to a transport cart that transports a product stored in a factory or the like from a predetermined position to another position, and particularly to a transport cart that carries a transport product at a high position and carries it out to a low position. Is preferred.

従来、図７（ａ）に示すように完成品置場（シュート）のローラーコンベア１に載置された製品等が収納された搬送物２を倉庫のローラーコンベア３に移動して搬送する場合、作業者Ａが完成品置場のローラーコンベア１から搬送物２を取って持ち、倉庫の方へ歩いて運び、倉庫のローラコンベア３の上に載置して搬送物２の搬送を行っている。そして搬送物２の重量は５〜１０Ｋｇ程度、一日の搬送回数はほぼ３４０回程度を要している。   Conventionally, as shown in FIG. 7 (a), when a transported product 2 containing products and the like placed on a roller conveyor 1 in a finished product storage (chute) is moved to a roller conveyor 3 in a warehouse and transported, The person A takes the conveyed product 2 from the roller conveyor 1 in the finished product storage area, carries it by walking toward the warehouse, and places it on the roller conveyor 3 in the warehouse to convey the conveyed product 2. The weight of the conveyed product 2 is about 5 to 10 kg, and the number of times of conveyance per day is about 340 times.

また、完成品置場のローラーコンベア１の高さＨ１（７４０ｍｍ程度）は倉庫のローラコンベア３の高さＨ２（５３０ｍｍ程度）より高くなっており、作業者２の搬送範囲も図７（ｂ）に示すように完成品置場と倉庫との距離Ｌは６ｍほどあり、また、倉庫の間口Ｍ（幅）は１８ｍほどあり、作業者Ａは重量のある搬送物２を、高さの異なる２位置間で相当の距離を持って搬送している。そのため作業者に多大な負荷がかかっている。   Further, the height H1 (about 740 mm) of the roller conveyor 1 in the finished product storage is higher than the height H2 (about 530 mm) of the roller conveyor 3 in the warehouse, and the transport range of the worker 2 is also shown in FIG. As shown, the distance L between the finished product storage area and the warehouse is about 6 m, the frontage M (width) of the warehouse is about 18 m, and the worker A moves the heavy transported object 2 between two positions having different heights. It is transported with a considerable distance. Therefore, a great load is applied to the worker.

また、従来より搬送物の搬送に搬送台車が使用されているが、従来の搬送台車を高さの異なる２位置間の搬送に使用した場合、搬送物を作業者が搬送台車に載せたり、搬送台車から降ろしたりしなければならず、やはり従来の搬送台車を使用しても作業者に相当の負荷がかかるという問題がある。   In addition, transport carts are conventionally used for transporting transported items, but when conventional transport carts are used for transport between two positions with different heights, workers can place transported products on transport carts, There is a problem that a considerable load is applied to the operator even if the conventional transport cart is used.

下記特許文献１に記載の搬送台車においても上述した同様の問題がある。
特開２００４−２２４２２９号公報 The conveyance cart described in Patent Document 1 below has the same problem as described above.

以下、本発明の実施形態を図に基づき説明する。図１、図２は本発明になる搬送台車の基本構造を示すもので、図２は図１の後部側から見た側面図である。説明文中「前部側」、「後部側」及び「上方向」、「下方向」の記載は図中に図示する方向を示す。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 and 2 show the basic structure of a transport carriage according to the present invention, and FIG. 2 is a side view seen from the rear side of FIG. In the description, “front side”, “rear side”, “upward direction”, and “downward direction” indicate directions shown in the drawing.

本発明搬送台車の基本構造は移動可能な搬送台車基台１０、搬送物２が載置される荷台２０、搬送台車基台１０と荷台２０との間に取付けられた荷台揺動手段３０を備えている。   The basic structure of the transporting carriage of the present invention includes a movable transporting carriage base 10, a loading platform 20 on which the transported object 2 is placed, and a loading platform swinging means 30 attached between the transportation cart base 10 and the loading platform 20. ing.

搬送台車基台１０は金属パイプ材よりなる４本（２本は図面の垂直方向にあるため図示されない）の支柱１１及び同材の横棒１２で矩形状に組立てられている。支柱１１の下部にはロック付きキャスター１３がそれぞれ取付けられている。また、搬送台車基台１０の後部側の２本の取付け棒１４ｂの方中央部には足踏みで操作する足踏みペダル１４ａ付きの停止ロック装置１４が取付けられており、ペダル１４ａを踏むと停止ロック装置１４が上下方向に伸びて地面に当接し搬送台車基台１０の後部側を持ち上げ搬送台車基台１０の移動をロックする。なお、当該停止ロック装置１４は通常使用されているものである。   The transport carriage base 10 is assembled in a rectangular shape with four columns 11 (not shown because two are in the vertical direction of the drawing) and horizontal bars 12 made of metal pipe material. Casters 13 with locks are respectively attached to the lower portions of the columns 11. Further, a stop lock device 14 with a foot pedal 14a operated by stepping is attached to the central portion of the two mounting rods 14b on the rear side of the transport carriage base 10, and when the pedal 14a is depressed, the stop lock device 14 extends in the vertical direction and abuts on the ground, lifts the rear side of the transport carriage base 10 and locks the movement of the transport carriage base 10. The stop lock device 14 is normally used.

荷台２０も金属パイプ材よりなる横棒２１で矩形状に組立てられおり、後部側には同材の把手棒２２が横棒２１に直角に取付けられている。把手棒２２には把手２３が水平に取付けられている。また、荷台２０の上面の両側には滑動具としてのローラーコンベアー２４が一対取付けられており、載置される搬送物２の滑動を良好にする。   The loading platform 20 is also assembled in a rectangular shape with a horizontal bar 21 made of a metal pipe material, and a handle bar 22 of the same material is attached to the horizontal bar 21 at a right angle on the rear side. A handle 23 is horizontally attached to the handle bar 22. In addition, a pair of roller conveyors 24 as sliding tools are attached to both sides of the upper surface of the loading platform 20 to improve the sliding of the transported object 2 to be placed.

荷台揺動手段３０は一対の前部側ロッド３１と一対の後部側ロッド３２を有し、両ロッド３１、３２の長さは同じであり、搬送台車基台１０と荷台２０にそれぞれヒンジ３３を介して揺動自在に取付けられている。各ロッド３１、３２の長さＬ１を本例では２４７ｍｍに設定している。なお、ロッド３１、３２の長さＬ１とは両端のヒンジ３３間の長さである。   The loading platform swinging means 30 has a pair of front side rods 31 and a pair of rear side rods 32. The lengths of both rods 31, 32 are the same, and hinges 33 are respectively provided on the transport carriage base 10 and the loading platform 20. It is attached so that it can swing freely. The length L1 of each rod 31, 32 is set to 247 mm in this example. The length L1 of the rods 31 and 32 is the length between the hinges 33 at both ends.

また、荷台２０側の前部側ロッド３１と後部側ロッド３２との荷台側ロッド間長さＬ２は搬送台車基台１０側の前部側ロッド３１と後部側ロッド３２との搬送台車基台側ロッド間長さＬ３より僅かに長く設定されている。本例では荷台側ロッド間長さＬ２を３７０ｍｍ、搬送台車基台側ロッド間長さＬ３を３５７ｍｍに設定している。なお、荷台側ロッド間長さＬ２、搬送台車基台側ロッド間長さＬ３とはヒンジ３３間の長さである。   Further, the length L2 between the front side rod 31 and the rear side rod 32 on the side of the loading platform 20 is equal to the length L2 between the front side rod 31 and the rear side rod 32 on the side of the transport cart base 10. It is set slightly longer than the length L3 between the rods. In this example, the length L2 between the loading platform side rods is set to 370 mm, and the length L3 between the conveyance carriage base side rods is set to 357 mm. The length L2 between the loading platform side rods and the length L3 between the conveyance carriage base side rods are the lengths between the hinges 33.

荷台２０側ロッド間長さＬ２を搬送台車基台１０側ロッド間長さＬ３より僅かに長く設定することにより、前部側ロッド３１と搬送台車基台１０の横棒１２とのなす角度Ｘが後部側ロッド３２と横棒１２とのなす角度Ｙより小さい状態をなす。なお、角度Ｘ、角度Ｙは図示するように前部側の角度を言う。   By setting the length L2 between the loading platform 20 side rods slightly longer than the length L3 between the conveyance carriage base 10 side rods, the angle X formed by the front side rod 31 and the horizontal bar 12 of the conveyance carriage base 10 is The state is smaller than the angle Y formed by the rear rod 32 and the horizontal bar 12. Note that the angles X and Y are front-side angles as shown in the figure.

荷台２０側ロッド間長さＬ２を搬送台車基台１０側ロッド間長さＬ３より僅かに長く設定することにより、両ロッド３１、３２の揺動により荷台２０は前部側へ揺動移動すると図１の点線で示すように荷台２０はその前部側が低くい傾斜状態を呈する。この傾斜状態は荷台２０側ロッド間長さＬ２と搬送台車基台１０側ロッド間長さＬ３との比が大きくなるに連れ、或は荷台２０の前部側への移動を多くすると、角度差（Ｙ−Ｘ）が次第に大きくなり荷台２０は次第に前部側への傾斜度合いが増す（急傾斜状態）。本発明では荷台２０を前部側方向へ傾斜させることにより、搬送物２の搬出時ローラーコンベアー２４を介しその自重を利用して行っている。   By setting the length L2 between the loading platform 20 side rods to be slightly longer than the length L3 between the transport carriage base 10 side rods, the loading platform 20 swings and moves forward due to the swinging of the rods 31 and 32. As indicated by the dotted line 1, the loading platform 20 exhibits an inclined state in which the front side is low. This inclined state causes an angular difference as the ratio of the length L2 between the loading platform 20 side rods and the length L3 between the conveyance carriage platform 10 side rods increases, or when the movement of the loading platform 20 to the front side increases. (YX) gradually increases and the loading platform 20 gradually increases the degree of inclination toward the front side (steep inclination state). In the present invention, the loading platform 20 is tilted in the front side direction, and the weight of the transported product 2 is utilized via the roller conveyor 24 when the transported product 2 is unloaded.

また、搬送台車基台１０の後部側には荷台２０を後部側へ揺動移動させた際（図１の実線で示す状態）、荷台揺動手段３０の後部側ロッド３２を所定位置に停止させる荷台後部側停止手段１５が設けられている。具体的には図２に示すように両支柱１１、１１を接続している横棒１５である。この荷台後部側停止手段１５によって荷台２０は水平状態もしくはやや後部側が前部側より下がった状態を呈する。従って、荷台２０の搬送物２は安定状態に載置される。   Further, when the loading platform 20 is swung to the rear side on the rear side of the transport carriage base 10 (state shown by the solid line in FIG. 1), the rear rod 32 of the loading platform rocking means 30 is stopped at a predetermined position. A loading platform rear side stop means 15 is provided. Specifically, as shown in FIG. 2, it is a horizontal bar 15 that connects both struts 11 and 11. By this loading platform rear side stop means 15, the loading platform 20 exhibits a horizontal state or a state in which the rear side is slightly lowered from the front side. Therefore, the conveyed product 2 on the loading platform 20 is placed in a stable state.

また、搬送台車基台１０の前部側には荷台２０を前部側へ揺動移動させた際（図１の点線で示す状態）、荷台揺動手段３０の前部側ロッド３１を所定位置に停止させる荷台前部側停止手段１６が設けられている。具体的には荷台後部側停止手段１５と同様両支柱１１、１１を接続している横棒１６である。この荷台前部側停止手段１６によって荷台２０は前部側へ低く傾斜した状態を保ち所定の高さ、すなわち倉庫のローラーコンベアー３の高さＨ２を維持する。従って、荷台２０の搬送物２はローラーコンベアー２４を介して前部側へ滑動する状態になる。なお、荷台前部側停止手段１６としての横棒１６が前部側の一対の支柱１１、１より少なくとも支柱１１、１１の幅（径）分だけ内側（後部側）に位置して固定されている。これは後述するように伸長折曲金具５２のヒンジ５１が支柱１１、１１のほぼ中心に位置し、伸長折曲金具５２がヒンジ５１で折れ曲がった際、伸長折曲金具５２が横棒１６に当接しないようにするためである。   Further, when the loading platform 20 is swung to the front side on the front side of the transport carriage base 10 (as indicated by the dotted line in FIG. 1), the front side rod 31 of the loading platform rocking means 30 is placed at a predetermined position. A loading platform front side stop means 16 is provided for stopping the vehicle. Specifically, it is a horizontal bar 16 that connects both struts 11 and 11 similarly to the loading platform rear side stop means 15. By this loading platform front side stop means 16, the loading platform 20 maintains a state of being inclined low toward the front side, and maintains a predetermined height, that is, the height H <b> 2 of the roller conveyor 3 in the warehouse. Therefore, the conveyed product 2 on the loading platform 20 is slid to the front side via the roller conveyor 24. The horizontal bar 16 as the loading platform front side stopping means 16 is positioned and fixed at the inner side (rear side) at least by the width (diameter) of the columns 11 and 11 than the pair of columns 11 and 1 on the front side. Yes. As will be described later, this is because the hinge 51 of the extension bent metal fitting 52 is located at the center of the support pillars 11 and 11 and the extension bent metal fitting 52 is bent by the hinge 51 so that the extension bent metal fitting 52 contacts the horizontal bar 16. This is to avoid contact.

図３（ａ）、（ｂ）により上記構成になる本発明搬送台車による搬送物２の搬入、搬出を説明する。   The carrying-in and carrying-out of the conveyed product 2 by the conveyance cart of the present invention configured as described above will be described with reference to FIGS.

まず、図３（ａ）に示すように搬送台車基台１０の前部側のキャスター１３を完成品置場のローラーコンベアー１の支柱に当接させて位置を定める。位置が定まると停止ロック装置１４のペダル１４ａを作業者が踏み、搬送台車基台１０の後部側のキャスター１３を浮き上がらせ搬送台車基台１０の位置をロックする。この時、荷台２０は実線で示す後部側に揺動した位置を呈する。   First, as shown in FIG. 3 (a), the caster 13 on the front side of the transport carriage base 10 is brought into contact with the support of the roller conveyor 1 in the finished product storage place to determine the position. When the position is determined, the operator steps on the pedal 14a of the stop lock device 14, and the caster 13 on the rear side of the transport carriage base 10 is lifted to lock the position of the transport carriage base 10. At this time, the loading platform 20 exhibits a position that swings toward the rear side indicated by a solid line.

次に荷台２０の把手２３を前部側へ押すと荷台揺動手段３０の前部側ロッド３１、後部側ロッド３２が前部側へ揺動移動し、荷台２０の前部が完成品置場のローラーコンベアー１に当接する。この場合完成品置場のローラーコンベアー１の高さと荷台２０のローラーコンベアー２４の高さが同じになるように前部側ロッド３１、後部側ロッド３２の長さが設定されている。また、この状態では荷台２０は極僅かに前部側に傾斜した状態を呈しているが搬送物２の完成品置場のローラーコンベアー１から荷台２０のローラーコンベアー２４への搬入にはほとんど支障を来たさない。また、本例では完成品置場のローラーコンベアー１の高さが倉庫のローラーコンベア３の高さより高いので、荷台２０の前部側への移動距離は小さくてよく、キャスター１３が最も前部側に位置するためキャスター１３を完成品置場のローラーコンベアー１に当接して搬入時の搬送台車基台１０の位置を定める。従って、搬入時は前部側ロッド３１は荷台前部側停止手段１６（横棒１６）に当接しない。   Next, when the handle 23 of the loading platform 20 is pushed to the front side, the front side rod 31 and the rear side rod 32 of the loading platform swinging means 30 swing and move to the front side. Contact the roller conveyor 1. In this case, the lengths of the front side rod 31 and the rear side rod 32 are set so that the height of the roller conveyor 1 in the finished product storage area and the height of the roller conveyor 24 in the loading platform 20 are the same. Further, in this state, the loading platform 20 is slightly inclined to the front side. However, the loading of the conveyed product 2 from the roller conveyor 1 in the finished product storage area to the roller conveyor 24 of the loading platform 20 is almost hindered. I will not. Moreover, in this example, since the height of the roller conveyor 1 in the finished product storage is higher than the height of the roller conveyor 3 in the warehouse, the moving distance to the front side of the loading platform 20 may be small, and the caster 13 is at the most front side. In order to position, the caster 13 is brought into contact with the roller conveyor 1 of the finished product storage place to determine the position of the transport carriage base 10 at the time of carry-in. Therefore, the front rod 31 does not contact the loading platform front side stop means 16 (horizontal bar 16) during loading.

搬送物２が荷台２０のローラーコンベアー２４上に載置されると把手２３を後部側に引き、前部側ロッド３１、後部側ロッド３２を後部側へ揺動させ後部側ロッド３２を荷台後部側停止手段１５に当接して荷台２０の後部側の位置を定める。   When the conveyed product 2 is placed on the roller conveyor 24 of the loading platform 20, the handle 23 is pulled to the rear side, the front side rod 31 and the rear side rod 32 are swung to the rear side, and the rear side rod 32 is moved to the rear side of the loading platform. The position on the rear side of the loading platform 20 is determined by contacting the stop means 15.

次に図３（ｂ）に示すように搬送台車基台１０を倉庫のローラーコンベアー３の近傍の所定の位置に止め停止ロック装置１４で搬送台車基台１０を停止ロックする。荷台２０の把手２３を前部側へ押出すと荷台揺動手段３０の前部側ロッド３１、後部側ロッド３２が前部側へ揺動移動し、荷台２０は点線で示すように前部側へ低く傾斜し、荷台２０の前部が倉庫のローラーコンベアー３に当接する。この場合、倉庫のローラーコンベアー３の高さＨ２が完成品置場のローラーコンベアー１の高さに比べて低い（本例では高さの差は２１０ｍｍ程度）ので荷台２０の前部側への傾斜はかなり生じる。そのため荷台２０のローラーコンベアー２４上の搬送物２はローラーコンベアー２４を介して自重により滑動し、倉庫のローラーコンベアー３上に移動し載置される。   Next, as shown in FIG. 3B, the transport carriage base 10 is stopped at a predetermined position near the roller conveyor 3 in the warehouse, and the transport carriage base 10 is stopped and locked by the stop lock device 14. When the handle 23 of the loading platform 20 is pushed forward, the front side rod 31 and the rear side rod 32 of the loading platform swinging means 30 swing and move to the front side, and the loading platform 20 is moved to the front side as indicated by the dotted line. The front of the loading platform 20 comes into contact with the roller conveyor 3 in the warehouse. In this case, since the height H2 of the roller conveyor 3 in the warehouse is lower than the height of the roller conveyor 1 in the finished product storage place (in this example, the height difference is about 210 mm), the inclination of the loading platform 20 toward the front side is It happens quite a bit. Therefore, the conveyed product 2 on the roller conveyor 24 of the loading platform 20 slides by its own weight via the roller conveyor 24, and moves and is placed on the roller conveyor 3 of the warehouse.

このように本発明においては、荷台揺動手段３０により荷台２０の高さを搬送物２の搬入高さ及び搬出高さに設定して荷台２０を前部側方向に低く傾斜させることができ、従って、搬送物２の搬入が容易となり、且つ搬送物の搬出も自重滑動させることができ作業者の搬送物の搬送作業の負荷を大幅に低減できる。また、荷台後部側位置停止手段１５及び荷台前部側位置停止手段１６を備えているから搬送物２が載置された荷台２０を所定の位置（搬送物の搬入位置及び搬出位置）に停止維持させることができる。   Thus, in the present invention, the height of the loading platform 20 can be set to the carry-in height and the carry-out height of the transported object 2 by the loading platform swinging means 30, and the loading platform 20 can be inclined low in the front side direction. Therefore, it becomes easy to carry in the conveyed product 2, and the carrying-out of the conveyed product can be slid by its own weight, so that the load of the conveyance work of the conveyed product by the operator can be greatly reduced. In addition, since the loading platform rear side position stopping means 15 and loading platform front side position stopping means 16 are provided, the loading platform 20 on which the conveyed product 2 is placed is stopped and maintained at predetermined positions (conveyed material loading position and unloading position). Can be made.

次に図４（ａ）、（ｂ）により本発明における搬送物移動停止手段４０を説明する。前部側ロッド３１にこの前部側ロッド３１に対して所定の角度Ｚで前部側及び上方向へ伸びる停止棒４１が固定されている。この搬送物移動停止手段４０の停止棒４１は図４（ｂ）に示すように前部側ロッド３１、後部側ロッド３２を後部側へ揺動させ後部側ロッド３２を荷台後部側停止手段１５に当接して荷台２０の後部側の位置を定めた状態で荷台２０の面に対してほぼ直交する状態を呈する。従って、本発明の搬送台車をその荷台２０に搬送物２を載置した状態で移動しても搬送物２が荷台２０から移動し落下するのを防止できる。なお、停止棒４１が荷台２０内に揺動する領域には停止棒４１と当接する部材は設けられていない。また、本例では停止棒４１の前部側ロッド３１に対する取付け角度Ｚは４０〜４５°である。   Next, the conveyed product movement stopping means 40 in the present invention will be described with reference to FIGS. A stop rod 41 is fixed to the front rod 31 and extends forward and upward at a predetermined angle Z with respect to the front rod 31. As shown in FIG. 4B, the stop rod 41 of the transported object movement stopping means 40 swings the front side rod 31 and the rear side rod 32 to the rear side, and causes the rear side rod 32 to become the loading platform rear side stop means 15. In a state in which the position on the rear side of the loading platform 20 is determined by abutting, a state substantially orthogonal to the surface of the loading platform 20 is exhibited. Therefore, even if the transporting carriage of the present invention is moved in a state where the transported article 2 is placed on the loading platform 20, the transported article 2 can be prevented from moving from the loading platform 20 and falling. In addition, the member which contact | abuts the stop stick | rod 41 is not provided in the area | region where the stop stick | rod 41 rocks in the loading platform 20. FIG. In this example, the attachment angle Z of the stop rod 41 to the front rod 31 is 40 to 45 °.

図３（ｂ）に示す状態では搬送台車基台１０の停止位置は床に前部側のキャスター１３の停止線を画く等して定めることができるが、搬送台車基台１０の停止位置を正確かつ迅速に設定するために本例では搬送台車基台位置停止手段とその収納手段が設けられている。以下図５、図６、図７により構成、作用を説明する。図５（ａ）、（ｂ）、（ｃ）は搬送台車基台位置停止手段５０をセットする状態を示し、図６（ａ）、（ｂ）、（ｃ）は搬送台車基台位置停止手段５０を搬送台車基台１０と荷台２０との間に収納手段６０により収納する状態を示す。図７は搬送台車基台位置停止手段５０及び収納手段６０の一部を示す前部側斜視図である。   In the state shown in FIG. 3B, the stop position of the transport carriage base 10 can be determined by drawing a stop line of the casters 13 on the front side on the floor. However, the stop position of the transport carriage base 10 can be accurately determined. In addition, in this example, a conveyance carriage base position stopping means and its storage means are provided for quick setting. Hereinafter, the configuration and operation will be described with reference to FIGS. 5, 6, and 7. FIGS. 5A, 5B, and 5C show a state where the conveyance carriage base position stopping means 50 is set, and FIGS. 6A, 6B, and 6C show the conveyance carriage base position stopping means. A state is shown in which 50 is stored by the storage means 60 between the transport carriage base 10 and the loading platform 20. FIG. 7 is a front perspective view showing a part of the transport carriage base position stopping means 50 and the storage means 60.

図５、図７において、搬送台車基台１０の前部側の一対の横棒１２には接続横棒１２ａが固定され、この接続横棒１２ａに直線状に前部側へ水平方向に伸長すると共にヒンジ５１により９０°以上折れ曲がる一対の伸長折曲金具５２が取付けられ、その先端は金具接続横棒５２ａで接続固定されている。金具接続横棒５２ａには水平方向直線状態の伸長折曲金具５２とほぼ直交（垂直）して上方に伸びるパイプ材のバンパー５３が固定されている。また、一対の横棒１２には接続補助棒１２ｂが水平に固定されおり、伸長折曲金具５２が直線状伸長状態になった時の伸長折曲金具５２の支え補助をする。従って、接続補助棒１２ｂは伸長折曲金具５２の厚み分だけ横棒１２の水平位置より低い位置に固定されている。また、一対のヒンジ５１は伸長折曲金具５２において支柱１２の近傍に位置している。   5 and 7, a connecting horizontal bar 12a is fixed to a pair of horizontal bars 12 on the front side of the transport carriage base 10, and the connecting horizontal bar 12a extends linearly in the horizontal direction to the front side. At the same time, a pair of elongated bent metal fittings 52 bent by 90 ° or more are attached by the hinge 51, and the tips thereof are connected and fixed by metal fitting connecting horizontal bars 52a. A bumper 53 of a pipe material extending substantially upward (perpendicular) to and perpendicular to the elongated bent metal fitting 52 in the horizontal direction is fixed to the fitting connecting horizontal bar 52a. Further, the connection auxiliary rod 12b is horizontally fixed to the pair of horizontal bars 12, and supports the extension bent metal fitting 52 when the extension bent metal fitting 52 is in a linearly extended state. Therefore, the connection auxiliary bar 12b is fixed at a position lower than the horizontal position of the horizontal bar 12 by the thickness of the elongated bent metal fitting 52. In addition, the pair of hinges 51 are positioned in the vicinity of the support column 12 in the elongated bent metal fitting 52.

バンパー５３は水平方向に伸び（図５では図面と直交方向に伸びている）金具接続横棒５２ａと共に四角状（パイプ材で四角状に組立てられた矩形状）になっており、バンパー５３の当接領域（面積）を広くしている。この伸長折曲金具５２（金具接続横棒５２ａも含む）とバンパー５３で搬送台車基台位置停止手段５０を構成している。   The bumper 53 extends in a horizontal direction (in FIG. 5, extends in a direction orthogonal to the drawing) and has a square shape (a rectangular shape assembled into a square shape with a pipe material) together with a metal connection horizontal bar 52a. The contact area (area) is widened. The extension bent metal fitting 52 (including the metal fitting connecting bar 52a) and the bumper 53 constitute the conveyance carriage base position stopping means 50.

なお、バンパー５３は伸長折曲金具５２の位置状態（例えば水平方向より上方向に少し傾斜した状態）に係わらず常に上方垂直（鉛直）状態になるように伸長折曲金具５２の固定されていることが望ましい。また、バンパー５３の上方垂直方向の高さ、水平方向（図５においては図面と直交する方向）の幅は使用する状況の応じて適宜その寸法を設定すればよい。また、バンパー５３には当接力が作用するため伸長折曲金具５２とは強固に固定することが望ましい。伸長折曲金具５２は直線状に前部側へ水平方向に伸長して位置状態が定まる構造が最も望ましい。これはバンパー５３に作用する当接力が水平方向であるため、この水平方向当接力を伸長折曲金具５２が上下方向に作用されることなく受け止めることができるためである。   The bumper 53 is fixed so that the bumper 53 is always vertically upward (vertical) regardless of the position of the extended bent metal 52 (for example, a state slightly inclined upward from the horizontal direction). It is desirable. Further, the height of the bumper 53 in the upper vertical direction and the width in the horizontal direction (in FIG. 5, the direction orthogonal to the drawing) may be appropriately set according to the situation of use. Further, since an abutting force acts on the bumper 53, it is desirable that the bumper 53 be firmly fixed to the elongated bent metal fitting 52. The extension bent metal fitting 52 is most preferably a structure in which the position state is determined by extending in a straight line in the horizontal direction toward the front side. This is because the abutting force acting on the bumper 53 is in the horizontal direction, and this horizontal abutting force can be received without the extension bent metal fitting 52 acting in the vertical direction.

次に、収納手段６０の構成を説明する。伸長折曲金具５２の先端とバンパー５２とを接続する金具接続横棒５２ａに荷台２０の後部側近傍に伸びる操作レバー６１が揺動自在に接続されている。操作レバー６１は伸長折曲金具５２、バンパー５３に対して所定の間隔（図５においては図面の直交方向の間隔）を持って接続されている。   Next, the configuration of the storage means 60 will be described. An operation lever 61 extending in the vicinity of the rear side of the loading platform 20 is swingably connected to a metal connection horizontal bar 52 a that connects the tip of the extended bent metal fitting 52 and the bumper 52. The operation lever 61 is connected to the elongated bent metal fitting 52 and the bumper 53 with a predetermined interval (interval in the orthogonal direction in the drawing in FIG. 5).

操作レバー６１の後部側近傍には操作レバー６１から斜め外側下方へ突出た係止レバー６２が設けてある。これは係止レバー６２は垂直下方に突出ていないので、その先端の位置は垂直下方に突出した場合より高い位置を保ち、後述する係止ピン２５が後部側から前部側へ移動する際、係止ピン２５が係止レバー６２の先端部に接触しても係止レバー６２が押上げられ易いようにしているためである。   In the vicinity of the rear side of the operation lever 61, a locking lever 62 that protrudes obliquely outward and downward from the operation lever 61 is provided. This is because the locking lever 62 does not protrude vertically downward, the position of the tip thereof is kept higher than when protruding vertically downward, and when the locking pin 25 described later moves from the rear side to the front side, This is because the locking lever 62 is easily pushed up even if the locking pin 25 contacts the tip of the locking lever 62.

また、荷台２０の側面には水平方向へ突出た断面円形の棒状係止ピン２５が設けられており、係止ピン２５の長さは操作レバー６１の位置より外側方向に充分長くしてあり、係止ピン２５が係止レバー６２と確実に係合する長さになっている。なお、操作レバー６１には荷台２０に保持するための操作レバー保持部６３が設けてある。   Further, a bar-like locking pin 25 having a circular cross section protruding in the horizontal direction is provided on the side surface of the loading platform 20, and the length of the locking pin 25 is sufficiently longer in the outward direction than the position of the operation lever 61. The locking pin 25 has such a length that the locking pin 25 is securely engaged with the locking lever 62. The operation lever 61 is provided with an operation lever holding portion 63 for holding it on the loading platform 20.

上記操作レバー６１、係止レバー６２及び係止ピン２５により搬送台車基台位置停止手段５０を搬送台車基台１０と荷台２０との間に収納する収納手段６０を構成している。   The operation lever 61, the locking lever 62, and the locking pin 25 constitute storage means 60 for storing the transport carriage base position stopping means 50 between the transport carriage base 10 and the loading platform 20.

以下、収納手段６０の作用を説明する。先ず、図５（ａ）に示すように荷台２０が後部側に位置した状態で倉庫の近傍に本発明搬送台車が移動してくる。この時、停止ロック装置１４はロックが外れた状態になっている。   Hereinafter, the operation of the storage means 60 will be described. First, as shown in FIG. 5A, the transport carriage of the present invention moves to the vicinity of the warehouse with the loading platform 20 located on the rear side. At this time, the stop lock device 14 is unlocked.

次に、図５（ｂ）に示すように操作レバー６１の操作レバー保持部６３を荷台２０から外して操作レバー６１を前部側へ移動させる。操作レバー６１の前部側への移動により搬送台車基台位置停止手段５０の伸長折曲金具５２とバンパー５３がその自重により前部側へ揺動移動し伸長折曲金具５２は水平状態、バンパー５３はほぼ垂直状態を呈する。これにより搬送台車基台位置停止手段５０が設定され倉庫のローラーコンベアー３に当接して搬送台車基台１０の位置を設定できる。その後、停止ロック装置１４を操作して搬送台車基台１０をロックする。   Next, as shown in FIG. 5B, the operation lever holding portion 63 of the operation lever 61 is removed from the loading platform 20, and the operation lever 61 is moved to the front side. By the movement of the operation lever 61 to the front side, the extension bent metal fitting 52 and the bumper 53 of the conveyance carriage base position stopping means 50 swing and move to the front side by its own weight, so that the extension bent metal fitting 52 is in a horizontal state and the bumper. 53 exhibits a substantially vertical state. Thereby, the conveyance carriage base position stop means 50 is set, and the position of the conveyance carriage base 10 can be set in contact with the roller conveyor 3 of the warehouse. Thereafter, the stop lock device 14 is operated to lock the transport carriage base 10.

このように搬送台車基台１０の前部側に搬送台車基台位置停止手段５０を設けることにより、搬送台車基台位置停止手段５０を所定の機材本例では倉庫のローラーコンベアー３に当接させるだけで搬送台車基台１０を所定の位置に停止させることができるので、目視等による停止位置の確認を要せず、従って作業者の搬送作業の負荷を軽減することができる。また、搬送台車基台位置停止手段５０を設けることにより、搬送台車基台１０の前部側とローラーコンベアー３との距離を正確にとることができるので、荷台２０を前部側へ揺動移動させた際、荷台２０の前部が倉庫のローラーコンベアー３に乗り上げるのを防止できる。また、操作レバー６１を前部側へ移動させると重心が前部側に移動して伸長折曲金具５２とバンパー５３は自重で図示するよな水平、垂直状態になる。従って、操作レバー６１を前部側へ長く移動させる必要はない。   Thus, by providing the transport carriage base position stop means 50 on the front side of the transport carriage base 10, the transport carriage base position stop means 50 is brought into contact with the roller conveyor 3 of the warehouse in this example. Therefore, since the transport carriage base 10 can be stopped at a predetermined position, it is not necessary to confirm the stop position by visual observation or the like, and therefore, it is possible to reduce the load on the transport work of the operator. Moreover, since the distance between the front side of the transport carriage base 10 and the roller conveyor 3 can be accurately obtained by providing the transport carriage base position stop means 50, the loading platform 20 is swung to the front side. When it is made to do, it can prevent that the front part of the loading platform 20 gets on the roller conveyor 3 of a warehouse. Further, when the operating lever 61 is moved to the front side, the center of gravity moves to the front side, and the extension bent metal fitting 52 and the bumper 53 are in a horizontal and vertical state as shown in its own weight. Therefore, it is not necessary to move the operation lever 61 to the front side for a long time.

次に、図５（ｂ）に示す状態から、作業者が搬送台車基台１０の例えば取り付け棒１４ｂに片足を掛け踏み押さえながら荷台２０を前部側へ移動させる。この時、係止ピン２５は係止レバー６２の先端部に軽く接触するが、係止ピン２５は係止レバー６２を軽く擦るながら前部側へ移動する。次に、図５（ｃ）示すように荷台２０を前部側へ移動させると上述したように荷台２０は前部側へ低く傾斜し、その先端すなわち荷台２０のローラーコンベアー２４の先端が倉庫のローラーコンベアー３の高さと一致し、荷台２０の搬送物２が倉庫のローラーコンベアー３上に移動載置される。この荷台２０の前部側への移動により、係止ピン２５も一緒に移動するが図示するように係止ピン２５は操作レバー６１の後部側に位置している。すなわち、係止ピン２５は操作レバー６１を通過しない。以上が搬送台車基台位置停止手段５０をセットする作動である。   Next, from the state shown in FIG. 5 (b), the operator moves the loading platform 20 to the front side while placing one foot on and pressing the mounting rod 14 b of the transport carriage base 10. At this time, the locking pin 25 makes slight contact with the tip of the locking lever 62, but the locking pin 25 moves to the front side while rubbing the locking lever 62 lightly. Next, as shown in FIG. 5 (c), when the loading platform 20 is moved to the front side, the loading platform 20 is inclined downward toward the front side as described above, and the tip thereof, that is, the tip of the roller conveyor 24 of the loading platform 20 is located at the warehouse. In line with the height of the roller conveyor 3, the conveyed product 2 on the loading platform 20 is moved and placed on the roller conveyor 3 of the warehouse. By the movement of the loading platform 20 toward the front side, the locking pin 25 also moves together, but the locking pin 25 is positioned on the rear side of the operation lever 61 as shown in the figure. That is, the locking pin 25 does not pass through the operation lever 61. The above is the operation of setting the transport carriage base position stopping means 50.

次に、図６（ａ）、（ｂ）、（ｃ）では搬送台車基台位置停止手段５０を搬送台車基台１０と荷台２０との間に収納手段６０により収納する作用を説明する。   6 (a), 6 (b), and 6 (c), the operation of storing the transport carriage base position stopping means 50 between the transport carriage base 10 and the loading platform 20 by the storage means 60 will be described.

先ず、図６（ａ）に示すように、停止ロック装置１４のロックを外し作業者が搬送台車基台１０の例えば取付け棒１４ｂに片足を掛け踏み押さえながら荷台２０を後部側へ移動させる。荷台２０の後部側への移動により係止ピン２５も一緒に後部側へ移動し始める。停止ロック装置１４のロックを外すと倉庫のローラーコンベアー３とバンパー５３との当接力が緩み、荷台２０の移動が容易になる。また、停止ロック装置１４のロックを外した後、搬送台車基台１０を少し後部側へ移動させ、バンパー５３をローラーコンベアー３から離し、ローラーコンベアー３とバンパー５３とを当接力を完全に無くした後荷台２０を後部側へ移動させてもよい。   First, as shown in FIG. 6A, the stop lock device 14 is unlocked, and the operator moves the loading platform 20 to the rear side while pressing and holding one foot on, for example, the mounting rod 14b of the transport carriage base 10. Due to the movement of the loading platform 20 to the rear side, the locking pin 25 also starts to move together with the rear side. When the stop lock device 14 is unlocked, the contact force between the roller conveyor 3 and the bumper 53 in the warehouse is loosened, and the loading platform 20 can be easily moved. Further, after unlocking the stop lock device 14, the transport carriage base 10 is moved to the rear side a little, the bumper 53 is separated from the roller conveyor 3, and the contact force between the roller conveyor 3 and the bumper 53 is completely eliminated. The rear carrier 20 may be moved to the rear side.

次に、図６（ｂ）に示すように、荷台２０の移動と共に係止ピン２５は操作レバー６１を前部側から後部側へ通過し、係止レバー６３に係合する。係止ピン２５が操作レバー６１を通過する際上述したように操作レバー６１と極軽微な接触があるが擦って通過する。更に、荷台２０を後部側へ移動させると係止ピン２５も後部側へ移動し、係合している係止レバー６２を移動させる。すなわち操作レバー６１を後部側へ移動させようとする。操作レバー６１の後部側への移動力により、操作レバー６１と先端で揺動自在に接続されている搬送台車基台位置停止手段５０としての伸長折曲金具５２がヒンジ５１の作用により後部側へ９０°以上折れ曲る。これにより伸長折曲金具５２と固定されているバンパー５３は更に後部側に揺動しながら移動する。そしてさらに荷台２０を後部側へ移動させると係止ピン２５も係止レバー６２を外方へ押上げて後部側へ移動する。   Next, as shown in FIG. 6B, the locking pin 25 passes the operation lever 61 from the front side to the rear side with the movement of the loading platform 20 and engages with the locking lever 63. When the locking pin 25 passes through the operation lever 61, as described above, there is an extremely slight contact with the operation lever 61, but the friction pin 25 rubs and passes. Further, when the loading platform 20 is moved to the rear side, the locking pin 25 is also moved to the rear side, and the engaged locking lever 62 is moved. That is, the operation lever 61 is moved to the rear side. Due to the moving force to the rear side of the operation lever 61, the extension bent metal fitting 52 as the transport carriage base position stopping means 50 that is swingably connected to the operation lever 61 at the tip is moved to the rear side by the action of the hinge 51. Bend over 90 °. As a result, the bumper 53 fixed to the elongated bent metal fitting 52 moves while swinging further to the rear side. When the loading platform 20 is further moved to the rear side, the locking pin 25 also pushes the locking lever 62 outward and moves to the rear side.

このようにして搬送台車基台位置停止手段５０（伸長折曲金具５２、バンパー５３）は搬送台車基台１０と荷台２０との間に収納される。従って、他の機材等への当たりや引っ掛りを防止できる。なお、この時伸長折曲金具５２が折れ曲がり更にバンパー５３が伸長折曲金具５２に対してほぼ垂直に固定されているので、伸長折曲金具５２とバンパー５３は図５（ｃ）に示すように後部側へ且つ上方向に大きく折れ曲り、前述したように荷台前部側位置停止手段１６としての横棒１６に当接することはない。   In this way, the transport carriage base position stopping means 50 (extension bent metal fitting 52, bumper 53) is stored between the transport carriage base 10 and the loading platform 20. Accordingly, it is possible to prevent hitting or catching on other equipment. At this time, since the extension bent metal fitting 52 is bent and the bumper 53 is fixed substantially perpendicular to the extension bent metal fitting 52, the extension bent metal fitting 52 and the bumper 53 are as shown in FIG. It does not bend greatly toward the rear side and upward, and does not come into contact with the horizontal bar 16 as the loading platform front side position stop means 16 as described above.

なお、係止ピン２５と係止レバー６３との係合により操作レバー６１が後部側へ移動し始めると伸長折曲金具５２とバンパー５３も後部側へ揺動移動し、伸長折曲金具５２とバンパー５３との自重により伸長折曲金具５２とバンパー５３が後部側への揺動を続けるため、操作レバー６１も自動的に後部側へ移動する。そのため作業者は操作レバー６１を後部側へ移動（引く）させることなく、荷台２０のみを後部側へ移動させるだけで操作レバー６１は一緒に元の位置に戻る。従って、作業者の搬送作業における操作レバー６１の戻し操作を省くことができ、搬送作業を軽減できる。以上が搬送台車基台位置停止手段５０を搬送台車基台１０と荷台２０との間に収納手段６０により収納する作用である。   When the operation lever 61 starts to move to the rear side due to the engagement between the locking pin 25 and the locking lever 63, the extension bent metal fitting 52 and the bumper 53 also swing and move to the rear side. Since the extension bent metal fitting 52 and the bumper 53 continue to swing to the rear side due to the weight of the bumper 53, the operation lever 61 also automatically moves to the rear side. Therefore, the operator does not move (pull) the operation lever 61 to the rear side, but only moves the loading platform 20 to the rear side, and the operation lever 61 returns to the original position together. Therefore, it is possible to omit the return operation of the operation lever 61 in the operator's transfer operation, and the transfer operation can be reduced. The above is the operation of storing the transfer carriage base position stopping means 50 between the transfer carriage base 10 and the loading platform 20 by the storage means 60.
