。[Detailed Description of the Invention] [Industrial Application Field] Generally, a long body is rotated around the axis with its axis facing sideways and its outer periphery supported by a rotating support. For example, if the outer diameter is slightly different in the longitudinal direction or if the axis is slightly tilted, a step phenomenon in which the object tries to swing in the direction of the axis is likely to occur. Therefore, the present invention
With the axis of the elongate body oriented substantially horizontally, a rotary support member that supports the elongate body rotatably around the axis is configured to rotate one side of the axis in the direction of the elongate body as the elongate body rotates. The present invention relates to a rotation support device that is provided with a stopper that restricts movement.

。Conventionally, in a rotational support device for an elongated body, rotational supports that rotatably support the elongated body are arranged at a plurality of locations in the longitudinal direction of the elongated body. In order to restrict movement in one direction in the axial direction, only a stopper against which the end of the elongated body abuts is provided.

で寿命が短くなり、回転支持体も早期に交換しなければ
ならず、不経済であるという問題があった。However, if the movement of the elongated body in one direction in the axial direction as the elongated body rotates is regulated by abutting it against a stopper, the rotational support body will , a reaction force from the stopper acts via the elongated body. In this case, a large frictional force along the axial direction acts between the elongated body and the rotating support. As a result, the surface of the elongated body support portion of the rotary support is rapidly worn, resulting in a shortened service life, and the rotary support must be replaced at an early stage, which is uneconomical.
本発明は上記欠点を解消し、長尺体の回転に伴う軸心方
向の一方への移動を、経済性よく阻止できる回転支持装
置を提供することを目的とする。SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and to provide a rotation support device that can economically prevent the elongated body from moving in one direction in the axial direction as it rotates.
上記目的を達成するため本発明は、ストッパの近くにあ

。In order to achieve the above object, the present invention divides a rotating support near a stopper into two parts in the height direction into a lower support part and an upper support part, and the upper support part is axially disposed relative to the lower support part. The upper support part is placed so as to be slidable in the axial direction, and the sliding surface between the two support parts is moved by the upper support part as the upper support part slides in the axial direction by the reaction force from the stopper. is formed on a cam surface that rises reversibly.
つまり、長尺体の軸心方向の移動がストッパに接当して
阻止された場合、前記ストッパからの反力が長尺体を介
して上部支持部に働く。前記上部支持部は、前記下部支
持部に対して前記軸心方向に摺動自在に載置してあるた
め、前記反力を受けて前記上部支持部は下部支持部に対
して長尺体の移動方向とは反対方向に摺動し始める。That is, when movement of the elongated body in the axial direction is prevented by contacting the stopper, a reaction force from the stopper acts on the upper support portion via the elongated body. Since the upper support part is mounted to be slidable in the axial direction with respect to the lower support part, the upper support part receives the reaction force and moves the elongated body against the lower support part. It begins to slide in the opposite direction to the direction of movement.
また、前記上部支持部と前記下部支持部との摺動面は、
前記ストッパからの反力による摺動に伴って、前記上部

分が他方側部分よりも上昇しようとする。前記長尺体が
傾斜しかかると、自重に対する分力して、軸心方向に沿

、ストッパから長尺体を介して上部支持部が受ける前記
反力は小さくなり、カム面による前記上部支持部の上昇
位置は、ストッパから受ける反力がほぼ零に近くなった
ところでつり合って定まる。Furthermore, the sliding surface between the upper support part and the lower support part is
Since the upper support part is formed on a cam surface that reversibly rises as the upper support part slides due to the reaction force from the stopper, the upper support part resists the own weight of the elongated body. It rises while sliding, and the stopper side portion of the elongated body tends to rise higher than the other side portion. When the elongated body begins to tilt, a force is generated in the direction away from the stopper along the axial direction as a component of its own weight, and a force is generated in the direction toward the stopper that is generated as the elongated body rotates. is reduced by the amount of component force relative to said body weight. As a result, the reaction force that the upper support part receives from the stopper via the elongated body becomes smaller, and the raised position of the upper support part by the cam surface is balanced when the reaction force received from the stopper becomes almost zero. Determined.
上記のように、本発明に係る回転支持装置では、前記回
転支持体に働く反力は常に減少させられるようになって
いるため、前記長尺体と回転支持体との間に働く摩擦力
は小さくなる。As described above, in the rotating support device according to the present invention, the reaction force acting on the rotating support is always reduced, so that the frictional force acting between the elongated body and the rotating support is reduced. becomes smaller.

なって、全体としてのランニングコストを安くすること
ができた。Therefore, wear on the surface of the elongate body support part of the rotary support is suppressed, the life of the elongate body support part surface is extended, and it is no longer necessary to frequently repair the surface. In addition, it is possible to save energy by using the movement of the elongated body itself to prevent the movement of the elongated body without using new power, and the power lost due to friction between the elongated body and the rotating support As a result, overall running costs can be reduced.
その結果、長尺体の回転に伴う軸心方向の一方への移動
