端状のベルトをかけ渡したベルトコンベヤにあっては、
ベルトをトラフ形ローラで支持して搬送物の落下を防止
している。2. Description of the Related Art In a belt conveyor in which an endless belt is stretched between a head pulley and a tail pulley,
The belt is supported by trough-shaped rollers to prevent the conveyed items from falling.
【０００３】上記のトラフ形ローラは、既知のように、
センタローラと、そのセンタローラに対して所要の角度
をもって傾斜する左右一対のサイドローラとから構成さ
れている。[0003] The above-mentioned trough roller is, as is known,
It is composed of a center roller and a pair of left and right side rollers that are inclined at a required angle with respect to the center roller.

ーブの内側に向けてすべり移動するという現象が発生す
る。By the way, if the trough-shaped roller is fixedly arranged with the center roller horizontal, a phenomenon occurs in which the belt is slid toward the inside of the curve due to centripetal force due to belt tension during operation of the curve conveyor. .
【０００５】上記のベルト張力による求心力は、カーブ

搬送物がこぼれ落ちる問題がある。The above-mentioned centripetal force due to the belt tension is different at the time of starting the operation of the curve conveyor and at the time of load operation. When the load is increased, the centripetal force is also increased. As the amount increases, the curved inner edge of the belt is disengaged from the side rollers, and there is a problem that the conveyed product spills.
【０００６】そこで、トラフ形ローラからベルトが外れ
ないようにした従来技術としては、特開昭６１−１７４
０２０号公報に示すものがある。Therefore, as a conventional technique for preventing the belt from coming off from the trough-shaped roller, Japanese Patent Laid-Open No. 61-174 has been proposed.
No. 020 publication.

ってベルトを支持するようになっている。In this system, a pair of lower carrier stands, each having two concave and convex upper surfaces with concave curved surfaces along the conveyor width direction, are provided on the conveyor frame along the length direction of the conveyor, with a predetermined interval in front and behind. And a pair of front and rear two pairs of upper and lower carrier stands connected to each other via a connecting frame are engaged with the lower carrier stand to convey the upper carrier stand to the lower carrier stand. The belt is supported by rollers that are supported on the upper carrier stand.

As shown in, the trough-shaped roller supporting the belt a is
It is composed of a center roller 1 and a pair of side rollers 2 and 2. The pair of side rollers 2 and 2 are arranged in an inclined shape in which the outer end portion is higher than the inner end.

によって支持されている。A pair of left and right leg members 4 and 4 are erected on the frame A'of the curve conveyor A, and a pair of arms 5 are provided at the upper ends of the leg members 4 and 4 and both side ends of the roller stand 3. The upper and lower ends of 5 are connected via a universal joint 6, and the roller stand 3 is suspended. As a result, the belt a of the curve conveyor A is attached to the center roller 1 and the side rollers 2 and 2.
Supported by.

ド３とに（図示の場合）ピンを介して取付けてある。The universal joint 6 is composed of, for example, a well-known ball and a holder that encloses the outer periphery of the ball. The holder is attached to the leg member 4 and the roller stand 3 (shown in the figure). In the case of), it is attached via a pin.
【００１６】さらに、ローラスタンド３の両側端間の中

Is rotatably connected to the support member 8 of the frame A ′.

大きくしてある）ある。In the above rotatable connection, the projecting shaft 9 provided upright on the supporting member 8 and the hole 10 of the projecting member 7 are fitted to each other (smooth rocking of the projecting member 7 is ensured. Therefore, the diameter of the hole 10 is made larger than the diameter of the protruding shaft 9 to some extent).
【００２０】なお、支持部材８は、フレームＡ´に鋼材

【００２１】さらに、ローラスタンド３の両側端には、
ベルトａの側縁に臨む当りローラ１１が設けてある。Furthermore, at both ends of the roller stand 3,
A contact roller 11 facing the side edge of the belt a is provided.
【００２２】図中１２はフレームＡ´に架設した脚材
４、４の取付け鋼材である。In the figure, reference numeral 12 is a steel material for attaching the leg members 4 and 4 which are erected on the frame A '.

間の二等分位置）から外れる。Now, when the curve conveyor A is activated, the tension of the carrier side belt a increases, and the centripetal force due to the belt tension causes the belt a to move toward the inside of the curve. That is, the center of the belt a (divided position between both side edges) deviates from the center of the roller stand 3 (divided position between both side ends).

支持する。At this time, a frictional force due to the meandering of the belt a is generated in the roller stand 3 through the center roller 1 and the pair of side rollers 2 and 2 which are in contact with the belt a, and the center roller 1 and the pair of side rollers 2 and 2 are formed. To act on
The roller stand 3 is rotated counterclockwise in FIG. 2 about a fulcrum portion (a rotatable connection portion by fitting the terminal projecting shaft 9 of the projecting member 7 and the hole 10) to rotate the belt a as a center roller. 1 and a pair of side rollers 2 and 2.
【００２５】上記回転の与えられたローラスタンド３
は、回転方向にアーム５、５を傾動させながら回転方向
端が上昇し、反対側端が降下して傾動する。The roller stand 3 to which the above rotation is applied
Causes the arm 5 and 5 to be tilted in the rotation direction, while the end in the rotation direction rises and the end on the opposite side falls and tilts.

の傾きも大きくなり、ベルトａの蛇行が大きくなる。Further, the belt tension varies depending on the weight of the conveyed product. The heavier the conveyed product, the larger the belt tension becomes. The belt tension correlates with the centripetal force. Therefore, when the centripetal force becomes large, the belt a is inside the curve. The roller stand 3 moves to a large distance and follows the movement.
Also increases, and the meandering of the belt a increases.

1, the side edge of the belt a hits, and the hit roller 11 touches the belt a.
When pushed up by, the roller stand 3 is pushed away (the center of the belt a deviates from the center of the curved conveyor frame A ′), and the belt centripetal force acts (inward)
The roller stand 3 which is biased and is rotated counterclockwise by pressing the side edge of the belt a against the hitting roller 11
2 rotates clockwise about the fulcrum portion as shown in FIG. 2 (as shown by the solid line in FIG. 6 from the state of the chain line in FIG. 6), and with this rotation, both arms 5 and 5 suspending the roller stand 3 are also shown. The left end of the roller stand 3 shown in FIG. 5 is lowered while the right end of the roller stand 3 shown in FIG. 5 is raised (tilted) while swinging from the position indicated by the five-dot chain line to the position shown by the solid line in FIG. The weights of the rollers 2 and 2 and the roller stand 3 having the slider 5 and the weight of the belt a and the conveyed object are added to act in the direction of gravity to restore the center of the belt a to the center of the curved conveyor frame A ′. Let

Of course, the plurality of rollers supported by the roller stand is not limited to the illustrated center roller and a pair of side rollers, and two or more right and left inverted eight-letter rollers are arranged so as to be recessed in the center from both sides. Sometimes.
