Description

この発明は、高い位置に各種品物を搬送するベルトコンベヤ、更に詳しくは、使用位置に対して移動させることができると共に、搬送方向の傾斜角度を任意に調節することで、排出側端部の高さを使用条件に応じて設定することができるベルトコンベヤに関する。 The present invention is a belt conveyor that conveys various items to a high position. More specifically, the belt conveyor can be moved with respect to the use position, and the height of the discharge end can be adjusted by arbitrarily adjusting the inclination angle in the conveyance direction. The present invention relates to a belt conveyor that can be set according to use conditions.

上記のようなベルトコンベヤ１は、図６に示すように、後端側を接地させる長いフレーム２に並べて取付けたローラ３群の外側にエンドレスのベルト４を巻回してコンベヤ本体５を形成し、このコンベヤ本体５の下部途中の位置を両側一対の支持脚６で支持し、この支持脚６が、フレーム２の定位置に上端が枢止された枢止側脚材７と、フレーム２の長さ方向に可動となるスライド機構を介してフレームを支持する可動側脚材８を接地側の下端で互いに結合し、この下端結合部分に車輪９を取付けてＶ字状に開脚するよう形成され、前記両側支持脚６の開脚角度を、前記フレーム２に固定したウインチ１０によるワイヤー１１の巻取りまたは繰り出しで変えることにより、支持したコンベヤ本体５の傾斜角度を変化させることができるようになっている。 As shown in FIG. 6, the belt conveyor 1 as described above forms an endless belt 4 by winding an endless belt 4 around a group of rollers 3 mounted side by side on a long frame 2 whose rear end is grounded. A position in the middle of the lower part of the conveyor body 5 is supported by a pair of support legs 6 on both sides. A movable leg member 8 that supports the frame is coupled to each other at the lower end on the ground side via a slide mechanism that is movable in the vertical direction, and a wheel 9 is attached to the lower end coupling portion to open the leg in a V shape. The inclination angle of the supported conveyor body 5 can be changed by changing the open leg angle of the both side support legs 6 by winding or unwinding the wire 11 by the winch 10 fixed to the frame 2. You have me.

従来、両側支持脚６の開脚角度を変化させるための機構は、コンベヤ本体５のフレーム２における枢止側脚材７の上端近傍位置にウインチ１０を固定配置し、このウインチ１０から引き出したワイヤー１１の先端を可動側脚材８の上端側と結合した構造になっており、前記ウインチ１０でワイヤー１１を巻取ると、可動側脚材８の上端が枢止側脚材７に接近することで支持脚６の開脚角度が狭くなり、コンベヤ本体５の途中が持ち上げられることで傾斜角度がきつくなり、排出側端部を高くすることができる。 Conventionally, a mechanism for changing the leg angle of the support legs 6 on both sides is that a winch 10 is fixedly arranged near the upper end of the pivot-side leg member 7 in the frame 2 of the conveyor body 5, and a wire drawn from the winch 10 is used. 11 is connected to the upper end side of the movable leg member 8, and when the wire 11 is wound by the winch 10, the upper end of the movable leg member 8 approaches the pivoting leg member 7. As a result, the leg opening angle of the support leg 6 is narrowed, and the inclination angle is tightened by raising the middle of the conveyor body 5 so that the discharge end can be raised.

また、ウインチ１０でワイヤー１１を繰り出すと、可動側脚材８の上端が枢止側脚材７から離れることで支持脚６の開脚角度が広くなり、コンベヤ本体５の途中が下降することで傾斜角度が緩くなり、排出側端部を低くすることができる。 Further, when the wire 11 is fed out by the winch 10, the upper leg of the movable leg member 8 is separated from the pivoting leg member 7, so that the opening angle of the support leg 6 is widened and the intermediate part of the conveyor body 5 is lowered. The inclination angle becomes loose, and the discharge side end can be lowered.

ところで、上記のようなベルトコンベヤ１における支持脚６は、Ｖ字状に開脚した状態でコンベア本体５の途中を支持しているので、常に開脚方向の負荷がかかることになり、この負荷をワイヤー１１を介してウインチ１０で支持することになるが、コンベヤ本体５の重量に加え、搬送物の重量や搬送物の荷下し時の衝撃がかかることで支持脚６に対する開脚方向の負荷が大きくなり、これを支持するウインチ１０に大型で能力の大きなものを使用しなければならず、従って、ベルトコンベヤ１の全体重量が大きくなり、移動操作が不便であるばかりでなく、ベルトコンベヤの製作コストが高くなるという問題がある。 By the way, since the support leg 6 in the belt conveyor 1 as described above supports the middle of the conveyor body 5 in a state where the leg is opened in a V shape, a load in the leg opening direction is always applied. Will be supported by the winch 10 through the wire 11, but in addition to the weight of the conveyor body 5, the weight of the conveyed product and the impact at the time of unloading the conveyed item are applied in the direction of the opening with respect to the support leg 6. The winch 10 supporting the load becomes large and a large capacity must be used. Therefore, not only the overall weight of the belt conveyor 1 is increased and the moving operation is inconvenient, but also the belt conveyor. There is a problem that the production cost of the is high.

そこで、この発明の課題は、支持脚の開脚や閉脚の調整に支障を与えることなく、支持脚における可動側脚材の上端を、フレームに対して開脚方向に移動しないように固定化することができ、開脚方向の負荷を支持脚自身で支持させることにより、使用するウインチの小型化を図ることができるベルトコンベヤを提供することにある。 Accordingly, an object of the present invention is to fix the upper end of the movable leg member of the support leg so as not to move in the open leg direction with respect to the frame without hindering the adjustment of the opening and closing of the support leg. It is possible to provide a belt conveyor capable of reducing the size of a winch to be used by supporting the load in the opening leg direction with the support legs themselves.

上記の課題を解決するため、この発明は、フレームの一方の端部側を接地させるコンベヤ本体の下部途中の位置を両側一対の支持脚で支持し、この支持脚が、フレームの定位置に枢止された脚材とフレームの長さ方向に可動となる脚材を接地側の下端で互いに結合して形成され、この両側支持脚のフレーム長さ方向の開脚角度を、前記フレームに固定したウインチによるワイヤーの巻取りまたは繰り出しで変えることにより、支持したコンベヤ本体の傾斜角度を変化させることができるようにしたベルトコンベヤにおいて、前記コンベヤ本体のフレームの長さ方向両側を形成する両側溝形材の内部に、この溝形材の長さ方向に移動可能となり、溝形材に対して任意の傾斜角度で、支持脚の開脚方向に移動が生じないよう溝形材の両フランジの内面に食い込むように作用するストッパーを組み込み、前記可動側脚材の上端に、この可動側脚材の支持脚開脚方向への移動力で、前記ストッパーを溝形材の両フランジの内面に食い込むように押圧する当接片を設けた構成を採用したものである。 In order to solve the above problems, the present invention supports a position in the middle of the lower part of the conveyor body that grounds one end of the frame with a pair of support legs on both sides, and the support legs pivot to a fixed position on the frame. A fixed leg and a leg that is movable in the length direction of the frame are joined together at the lower end on the grounding side, and the open leg angle in the frame length direction of both side support legs is fixed to the frame. In a belt conveyor that can change the inclination angle of the supported conveyor body by changing the winding or unwinding of the wire with a winch, both side groove members forming both sides in the length direction of the frame of the conveyor body inside, it can move in the longitudinal direction of the groove profile, at any inclination angle relative to the groove profile, the flanges of the interposition member so that movement in the open leg direction of the support leg does not occur in Built a stopper that acts to bite into the surface, the upper end of the movable leg member, in moving force to the support leg open leg direction of the movable leg member, the stopper on the inner face of both flanges of the interposition member The structure provided with the contact piece which presses so that it may bite in is employ | adopted.

上記ストッパーは、長辺に対し短辺が傾斜する平行四辺形に形成されて、フレームの溝形材のフランジ内面長さ方向に長辺が沿った状態では、可動側脚材の上端の前記溝形材の長さ方向の移動に伴ってその長さ方向に移動可能であり、ウインチの巻取りまたは繰り出しを停止して前記フランジ内面長さ方向に短辺が沿った傾斜状態では、前記可動側脚材の支持脚開脚方向への移動力に基づく当接片の押圧によって両短辺の端部が前記両フランジ内面に食い込んで支持脚の開脚方向に移動しないようになっており、このストッパーに、溝形材のウェブ内面に対する固定用の押付けねじを取付けた構造とすることができる。 Said stopper is formed in a flat row quadrilateral short side to the long side is inclined, in the state where the flange inner surface long side in the length direction of the groove profile is along the frame, the upper end of the movable leg member The groove shape can be moved in the length direction along with the movement in the length direction, and when the winding or feeding of the winch is stopped and the short side is inclined in the length direction of the flange inner surface, the movable portion is movable. The end of both short sides bite into the inner surfaces of both flanges by pressing the contact piece based on the moving force in the supporting leg opening direction of the side leg material so that it does not move in the opening direction of the supporting leg. this stopper may be structured fitted with pressing screws for fixing to the web plane of the Mizokatachizai.

また、上記ストッパーと上記両側支持脚の可動側脚材の上端を、溝形材の長さ方向に一体となって移動するよう連結部材を介して連結した構造としてもよい。 Moreover, it is good also as a structure which connected the upper end of the movable side leg material of the said stopper and the said both-sides support leg via the connection member so that it might move integrally in the length direction of a channel shape material.

ここで、上記コンベヤ本体は、後端側に設けたテールヘッドを接地させる長いフレームに多数のローラを並べて取付け、このローラ群の外側にエンドレスのベルトを巻回するとともに、テールヘッド内に設けたモータでベルトを駆動するようになっている。 Here, the conveyor body is mounted with a large number of rollers arranged side by side on a long frame for grounding the tail head provided on the rear end side, and an endless belt is wound around the outside of the roller group and provided in the tail head. The belt is driven by a motor.

上記支持脚は金属パイプ製であり、枢止側脚材は、その上端をフレームの溝形材に固定した腕板にピン結合によって取付け、可動側脚材は、上端の腕板側面に枢止した鍔付きローラで溝形材の下面を支持し、上端が溝形材の長さ方向に移動可能になっていると共に、枢止側脚材と可動側脚材の下端は軸で互いに枢止結合され、この結合軸に接地用の車輪が取付けられている。 The support leg is made of a metal pipe, and the pivoting leg is attached to the arm plate with its upper end fixed to the groove of the frame by pin connection, and the movable leg is pivoted to the side of the upper arm plate. The lower surface of the channel member is supported by the ridged roller, the upper end is movable in the length direction of the channel member, and the lower end of the pivot side leg member and the movable side leg member are pivoted together by the shaft. A grounding wheel is attached to the coupling shaft.

両側の支持脚は、枢止側脚材同士が横桟で、また、可動側脚材同士が横桟でそれぞれ結合され、手動もしくは電動のウインチから引き出したワイヤーの先端は、可動側脚材同士を結合する最上部横桟に連結されている。 The support legs on both sides are connected to each other by the side rails at the pivot side and between the side legs at the movable side, and the tip of the wire drawn from the manual or electric winch It is connected to the top horizontal rail that joins.

上記コンベヤ本体のフレームを形成する溝形材は、一方の側面が上下に鍔壁を残して開放する断面形状になり、開放側面を外側にして両側に平行配置することによりフレームを形成し、この溝形材の内部に組み込んだストッパーは、上下の鍔壁によって外部に離脱しないようになっていると共に、このストッパーと上記可動側脚材の上端を連結する連結部材は、バネや強度のある線状物又は紐状物を用い、可動側脚材の上端に設けた腕板の外面に突設したピンもしくは押付けねじと、ストッパーの外面で中央よりも下寄りの位置に突設したピンもしくは当接片の端部の間に張設し、可動側脚材の上端とストッパーを溝形材の長さ方向に一体動させることができるようにしている。 The groove forming material forming the frame of the conveyor body has a cross-sectional shape in which one side surface is opened up and down leaving a wall, and the frame is formed by arranging the open side surface in parallel on both sides. The stopper incorporated in the inside of the channel is not separated from the outside by the upper and lower ribs, and the connecting member that connects the stopper and the upper end of the movable leg member is a spring or a strong wire. Pin or pressing screw projecting on the outer surface of the arm plate provided on the upper end of the movable leg member and a pin projecting or projecting at a position lower than the center on the outer surface of the stopper. It is stretched between the end portions of the contact pieces so that the upper end of the movable side leg member and the stopper can be integrally moved in the length direction of the channel member.

また、上記当接片は、可動側脚材の上端に設けた腕板の内面で上部の位置に突設され、任意の位置に固定したストッパーの下端部寄りの位置を開脚方向に押圧することで、その押圧力がストッパーに対してストッパーの上下端部が溝形材の上下面に食い込むように作用し、ストッパーと当接片で可動側脚材の上端を開脚側に移動しないように固定することで、支持脚自身が荷重を支持するようにしている。 Further, the abutting piece protrudes at an upper position on the inner surface of the arm plate provided at the upper end of the movable leg member, and presses the position near the lower end of the stopper fixed at an arbitrary position in the leg opening direction. Therefore, the pressing force acts on the stopper so that the upper and lower ends of the stopper bite into the upper and lower surfaces of the channel material, so that the upper end of the movable leg member does not move to the open leg side with the stopper and the abutting piece. By fixing to, the support leg itself supports the load.

この発明によると、コンベヤ本体のフレームを形成する両側溝形材の内部に、この溝形材に対して任意の傾斜角度で、支持脚の開脚方向に移動が生じないよう溝形材の上下面に食い込むように作用するストッパーを組み込み、前記可動側脚材の上端に、この可動側脚材の支持脚開脚方向への移動力で、前記ストッパーを溝形材の上下面に食い込むように押圧して傾斜させる当接片を設けたので、支持脚がＶ字状に開脚してコンベヤ本体を支持する状態で、可動側脚材の当接片が開脚方向への移動力でストッパーを溝形材の上下面に食い込むように押圧し、可動側脚材の上端を開脚方向へ移動しないように固定化でき、これによって支持脚自身でコンベヤ本体と搬送物の荷重や搬送物の荷下し時の衝撃を支持することができ、支持脚の開脚や閉脚を操作するウインチに大きな負荷がかからないので、小型で小能力のウインチを使用することができるようになり、ベルトコンベヤの軽量化とコスト削減を実現することができる。 According to the present invention, the upper side of the groove shape member is prevented from moving in the opening direction of the support leg at an arbitrary inclination angle with respect to the groove shape member inside the both side groove shape members forming the frame of the conveyor body. A stopper acting so as to bite into the lower surface is incorporated, and the stopper is bited into the upper and lower surfaces of the channel-shaped material at the upper end of the movable side leg member by the moving force of the movable side leg member toward the supporting leg opening leg direction. Since the contact piece that is pressed and inclined is provided, the support leg is opened in a V shape to support the conveyor body, and the contact piece of the movable side leg member is a stopper with a moving force in the opening direction. Can be fixed so that the upper end of the movable leg is not moved in the direction of the opening leg, and the support leg itself can Can support shocks when unloading, and support legs open and close Since not applied high load on the winch operating the, will be able to use a winch of small capacity compact, it is possible to realize the weight reduction and cost reduction of the belt conveyor.

また、ストッパーは、可動側脚材の閉脚方向への移動が自由となり、また、溝形材の長さ方向に沿わせれば、可動側脚材を開脚方向へ移動させることができるので、ワイヤーを介してウインチの操作で支持脚の開脚と閉脚が可能となり、コンベヤ本体における排出側端部の高さ調整が支障なく行えると共に、このストッパーと可動側脚材の上端を溝形材の長さ方向に一体となって移動するよう連結すれば、可動側脚材の開脚角度の調整時に可動側脚材の上端近傍にストッパーが常にあるので、開脚角度の調整作業が効率よく行える。 In addition, the stopper can move the movable leg in the closing leg direction, and if the stopper is moved along the length direction of the channel, the movable leg can be moved in the leg opening direction. The support leg can be opened and closed by operating the winch, and the height of the discharge side end of the conveyor body can be adjusted without hindrance. If they are connected so as to move together in the vertical direction, there is always a stopper in the vicinity of the upper end of the movable leg when adjusting the leg angle of the movable leg, so that the adjustment of the leg angle can be performed efficiently.

更に、ストッパーに、溝形材の側面に対する固定用の押付けねじを取付けたので、溝形材の任意の位置にストッパーを移動しないよう固定化することができ、ストッパーの固定位置を選ぶだけで可動側脚材の開脚角度を設定できる。 In addition, since a pressing screw for fixing the side surface of the channel is attached to the stopper, it can be fixed so that the stopper does not move to any position on the channel, and it can be moved simply by selecting the fixing position of the stopper. The leg angle of the side legs can be set.

また、可動側脚材２６の上端に設けた腕板３４の内面で上部の位置に当接片４２が突設してあり、この当接片４２でストッパー４０の下端部寄りの位置を開脚方向に押圧することで、傾斜状態にしたストッパー４０の上下端部を溝形材３３の上下面に食い込ませるようにし、ストッパー４０を開脚側に移動しないように固定することで、支持脚２４がコンベヤ本体２３の荷重を支持するようにしている。 Further, a contact piece 42 protrudes at an upper position on the inner surface of the arm plate 34 provided at the upper end of the movable leg member 26, and the contact piece 42 opens the position near the lower end portion of the stopper 40. By pressing in the direction, the upper and lower ends of the inclined stopper 40 are caused to bite into the upper and lower surfaces of the groove member 33, and the stopper 40 is fixed so as not to move to the open leg side, thereby supporting legs 24. Supports the load of the conveyor body 23.

この発明のベルトコンベヤ２１は、上記のような構成であり、Ｖ字状に開脚させた支持脚２４の車輪３７とテールヘッド２９のテール車輪３０を接地させることにより、コンベヤ本体２３を任意の傾斜角度で支持し、コンベヤ本体２３の上部排出端を荷揚げ位置に臨ませた状態でベルト３２を駆動し、テールヘッド側から供給した搬送物を荷揚げ位置に搬送するものである。 The belt conveyor 21 of the present invention is configured as described above, and the conveyor main body 23 can be arbitrarily set by grounding the wheel 37 of the support leg 24 and the tail wheel 30 of the tail head 29 which are opened in a V shape. The belt 32 is driven in a state where it is supported at an inclination angle and the upper discharge end of the conveyor body 23 faces the unloading position, and the conveyed product supplied from the tail head side is conveyed to the unloading position.

上記ベルトコンベヤ２１において、図２（ａ）と（ｂ）のように、ストッパー４０は溝形材３３の長さ方向に対して上端が搬送方向の前方に位置する傾斜状態で、押付けねじ４３をねじ込んで溝形材３３に固定され、開脚する支持脚２４の可動側脚材２６の上端に設けた当接片４２が前記ストッパー４０に当接し、このストッパー４０の下部を開脚方向に押圧することで、図４（ａ）の矢印のように、押圧力がストッパー４０の上下端部が溝形材３３の上下面に食い込むように作用し、これによって、ストッパー４０は可動側脚材２６の上端を開脚側に移動しないように固定することになり、支持脚２４のＶ字状開脚角度を固定化し、支持脚２４は自身で荷重を支持することで、可動側脚材２６の上端部に連結したワイヤー２８を介してウインチ２７に大きな負荷をかけないようにする。 In the belt conveyor 21, as shown in FIGS. 2 (a) and 2 (b), the stopper 40 is in an inclined state in which the upper end is located in front of the conveying direction with respect to the length direction of the channel member 33, and the pressing screw 43 is A contact piece 42 provided at the upper end of the movable leg member 26 of the support leg 24 that is screwed and fixed to the channel member 33 and that opens is in contact with the stopper 40 and presses the lower part of the stopper 40 in the leg opening direction. 4A, the pressing force acts so that the upper and lower end portions of the stopper 40 bite into the upper and lower surfaces of the groove member 33, whereby the stopper 40 is moved to the movable leg 26. The upper end of the support leg 24 is fixed so as not to move to the open leg side, the V-shaped open leg angle of the support leg 24 is fixed, and the support leg 24 supports the load by itself. Wipe through the wire 28 connected to the upper end. So as not to apply a large load to the switch 27.

上記ベルトコンベヤ２１において、コンベヤ本体２３の傾斜角度を荷揚げ位置の高さ条件に合わせて変更するには、図５（ｂ）のように、支持脚２４の可動側脚材２６を閉脚方向に移動させて上部排出端を高くする場合と、図５（ａ）のように、支持脚２４の可動側脚材２６を開脚方向に移動させて上部排出端を低くする場合がある。 In the belt conveyor 21, in order to change the inclination angle of the conveyor body 23 according to the height condition of the unloading position, the movable leg 26 of the support leg 24 is moved in the closing leg direction as shown in FIG. In some cases, the upper discharge end is raised, and as shown in FIG. 5A, the movable leg 26 of the support leg 24 is moved in the opening direction to lower the upper discharge end.

前者の上部排出端を高くする場合は、ストッパー４０の押付けねじ４３を緩めた状態で、ウインチ２７を操作してワイヤー２８を巻き取るようにすると、可動側脚材２６の上端が引かれて枢止側脚材２５に接近し、支持脚２４は開脚角度が狭くなることでコンベヤ本体２３を押し上げることになる。 In the case of increasing the former upper discharge end, if the winch 27 is operated to wind the wire 28 while the pressing screw 43 of the stopper 40 is loosened, the upper end of the movable leg 26 is pulled and pivoted. The support leg 24 approaches the stop-side leg member 25 and pushes up the conveyor body 23 as the opening leg angle becomes narrow.

このとき、可動側脚材２６の上端に連結部材４１を介して連結したストッパー４０は、その長辺を溝形材３３の長さ方向に沿わせ、その下端側が支持脚２４の閉脚方向に引かれることで、短辺４０ａの端部が溝形材３３の上下面に食い込まないようになり、従って、可動側脚材２６の上端とストッパー４０は、閉脚方向へ支障なく移動し、コンベヤ本体２３の上部排出端が所定高さになると、ウインチ２７によるワイヤー２８の巻き取りを止める。 At this time, the stopper 40 connected to the upper end of the movable leg member 26 via the connecting member 41 has its long side along the length direction of the groove member 33 and its lower end side pulled in the closing leg direction of the support leg 24. As a result, the end portion of the short side 40a does not bite into the upper and lower surfaces of the channel member 33. Therefore, the upper end of the movable leg member 26 and the stopper 40 move without trouble in the closing leg direction, and the conveyor body 23 When the upper discharge end of the wire reaches a predetermined height, the winding of the wire 28 by the winch 27 is stopped.

上記ストッパー４０は、移動後の位置で、溝形材３３の長さ方向に対して傾斜させた後、押付けねじ４３をねじ込んで溝形材３３に固定化し、可動側脚材２６の上端に設けた当接片４２をストッパー４０の下部に当接させると、可動側脚材２６の開脚方向の力が当接片４２を介してストッパー４０に加わり、当接片４２の押圧力がこのストッパー４０の上下短辺４０ａ端部を溝形材３３の上下面に食い込ませるように作用し、可動側脚材２６の上端が溝形材３３に対して開脚方向に固定化するので、調整後の支持脚２４の開脚角度を保持することになる。 The stopper 40 is tilted with respect to the length direction of the groove member 33 at the position after the movement, and is then screwed into the groove member 33 to be fixed to the groove member 33, and is provided at the upper end of the movable leg member 26. When the contact piece 42 is brought into contact with the lower portion of the stopper 40, the force in the opening direction of the movable leg member 26 is applied to the stopper 40 via the contact piece 42, and the pressing force of the contact piece 42 is applied to the stopper. Since the upper and lower short side 40a ends of 40 act on the upper and lower surfaces of the groove member 33, and the upper end of the movable leg member 26 is fixed to the groove member 33 in the leg opening direction. The opening leg angle of the supporting leg 24 is maintained.

また、後者の上部排出端を低くする場合は、先ず、図４（ｂ）のように、ストッパー４０の押付けねじ４３を緩めた状態で、ストッパー４０の長辺を溝形材３３の長さ方向に沿うよう倒し、次に、ウインチ２７を操作してワイヤー２８を繰り出すようにすると、Ｖ字状に開脚する支持脚２４に加わる荷重の開脚作用で、可動側脚材２６の上端は開脚方向に移動し、支持脚２４の開脚角度が広がることでコンベヤ本体２３の上部排出端が下降して所定高さになると、ウインチ２７によるワイヤー２８の繰り出しを止める。 In order to lower the upper discharge end of the latter, first, as shown in FIG. 4B, the long side of the stopper 40 is extended in the length direction of the groove member 33 with the pressing screw 43 of the stopper 40 loosened. Next, when the winch 27 is operated to feed the wire 28, the upper end of the movable leg 26 is opened by the leg opening action of the load applied to the support leg 24 that opens in a V shape. When the upper discharge end of the conveyor body 23 is lowered and reaches a predetermined height by moving in the leg direction and the leg opening angle of the support leg 24 is widened, the feeding of the wire 28 by the winch 27 is stopped.

この状態で、ストッパー４０を、溝形材３３の長さ方向に対して傾斜させ、その下端部寄りの位置を当接片４２に当接させて押付けねじ４３をねじ込み、図４（ａ）の状態に戻せば、可動側脚材２６の開脚方向の力が当接片４２を介してストッパー４０に加わり、このストッパー４０は上下短辺４０ａ、４０ａ端部が溝形材３３の上下面に食い込むように作用し、可動側脚材２６の上端が開脚方向に対して固定化するので、調整後の支持脚２４の開脚角度を保持することになる。 In this state, the stopper 40 is inclined with respect to the length direction of the groove member 33, the position near the lower end thereof is brought into contact with the contact piece 42, and the pressing screw 43 is screwed in, as shown in FIG. When returning to the state, the force in the opening direction of the movable leg member 26 is applied to the stopper 40 via the contact piece 42, and the stopper 40 has upper and lower short sides 40 a and 40 a ends on the upper and lower surfaces of the channel member 33. Since the upper end of the movable leg member 26 is fixed with respect to the leg opening direction, the leg angle of the support leg 24 after adjustment is maintained.

このように、コンベヤ本体２３の開脚角度の調整後は、可動側脚材２６の上端がストッパー４０を介して溝形材３３に開脚方向へ移動しないよう固定化されるので、支持脚２４自身でコンベヤ本体２３と搬送物の重量や搬送物の荷下し時の衝撃を支持することができ、ワイヤー２８を介して支持脚２４の開脚や閉脚を操作するウインチ２７に大きな負荷がかからないので、使用するウインチ２７の小型、小能力化を実現することができる。 Thus, after adjusting the leg opening angle of the conveyor body 23, the upper end of the movable leg member 26 is fixed to the groove member 33 via the stopper 40 so as not to move in the leg opening direction. The conveyor body 23 and the weight of the conveyed product and the impact when the conveyed product is unloaded can be supported by itself, and a large load is not applied to the winch 27 for operating the opening leg and the closing leg of the supporting leg 24 via the wire 28. Therefore, the winch 27 to be used can be reduced in size and capacity.
