And the endless transport chain 1 is
Is moved in the direction of the arrow (clockwise) by the rotation drive of
The coil 10 is sent from the exit side (the right side in the figure) of the endless transport chain 1 to the next step.

て構成されている。As shown in FIG. 6, such an endless endless transport chain 1 is composed of two rows in which adjacent link plates 3 and 3 are rotatably connected by a roller shaft across a roller 2 in a chain. , And the two rows of link plates 3 are connected appropriately by a connecting pipe 6 and an L-shaped steel 5.

ている。Here, the link plate at the position where the coil 10 is mounted has a different shape, and as shown in FIG. 3, a support member 7 with a saddle 8 extending in the coil supporting direction is used. The link plate 3 adjacent to the member 7 is rotatably connected by a roller shaft with the roller 2 interposed therebetween.
【0006】リンクプレート3が鎖状に連結されている
ピッチP1は、図7で示すようにスプロケット11の歯
ピッチに対応しているが、装置のコンパクト化のために
はスプロケット11の外径寸法が小さい方が望ましい。
スプロケット11は本質的には多角形であるため、回転
そのものは等角速度で回転しても無端搬送チェーンは等
速とはならず、スプロケット11の多角形に応じて不等
速となる。無端搬送チェーンを低速で動かす場合には問
題とならないが、高速で動かす場合はスプロケット11
の歯数を多くして無端搬送チェーンの動きを円滑化させ
ている。The pitch P1 at which the link plates 3 are connected in a chain shape corresponds to the tooth pitch of the sprocket 11 as shown in FIG. 7, but in order to make the apparatus compact, the outer diameter of the sprocket 11 is reduced. Is desirable.
Since the sprocket 11 is essentially a polygon, even if the rotation itself is rotated at a constant angular speed, the endless transport chain does not have a constant speed, but has an irregular speed according to the polygon of the sprocket 11. This is not a problem when the endless transport chain is moved at a low speed.
The number of teeth is increased to make the movement of the endless transport chain smooth.
【0007】このため、搬送チェーン速度によってスプ
ロケット11の歯数が制限されており、例えば、搬送チ
ェーン速度が15m/minの低速であれば歯数が6で
あるが、30m/minの中速であれば歯数が10、6
0m/minの高速であれば歯数が20のように適宜選
定されている。For this reason, the number of teeth of the sprocket 11 is limited by the speed of the transfer chain. For example, if the speed of the transfer chain is as low as 15 m / min, the number of teeth is 6, but if the speed of the sprocket 11 is 30 m / min. If there are 10, 6 teeth
At a high speed of 0 m / min, the number of teeth is appropriately selected such as 20.
【0008】一方、スプロケット11の歯数を多くする
と、スプロケット11の外形が大きくなり装置が巨大と
なる欠点がある。従って、高速搬送コンベアでは無端搬
送チェーンのピッチを小さくして対応する必要があっ
た。On the other hand, when the number of teeth of the sprocket 11 is increased, there is a disadvantage that the outer shape of the sprocket 11 becomes large and the device becomes huge. Therefore, it has been necessary to reduce the pitch of the endless transport chain in a high-speed transport conveyor.

を支持することができるようになっていた。[0009] When conveying chain speed is normally low, as shown in FIG. 3, the pitch P 1 is, for example, 625
mm, the lower dimension of the support member 7 also increases, and even when the coil 10 has the maximum outer diameter D (or the minimum outer diameter d), the point of action A (or the point of action a) of the force is It is located between the rollers 2 and 2 at the lower part of the supporting
I was able to support.

Since it is as small as 250 mm, the supporting material 7a
Is smaller, and in the case of the maximum outer diameter D (or the minimum outer diameter d) of the coil 10, the point of action A (or the point of action a) of the force is outside the rollers 2, 2 below the support member 7a. As a result, a falling moment is generated in the support member 7a, and the support of the coil 10 becomes unstable.

小さくする必要があった。In the above-described conventional coil transfer device of the rolling equipment, when it is desired to set the transfer chain speed to be high, the driving force of the sprocket is smoothed and the endless transfer chain is moved smoothly. In addition, it is necessary to increase the number of sprocket teeth to reduce the pitch of the endless transport chain.

A link plate at a position supporting the inner coil of the link plate is extended in the coil supporting direction to form a support member, and a saddle for supporting the coil outer peripheral surface is provided at the top of the support member,
An auxiliary plate fixed to the side of the support member for preventing overturning and a stopper fixed to the upper surface of the link plate at a position facing the lower surface of the auxiliary plate are provided, and the lower surface of the auxiliary plate abuts the stopper. Thus, the overturning moment of the support member is suppressed.
