Abstract

PROBLEM TO BE SOLVED: To rotate and reversely rotate a long shape steel product with a simple structure having a single driving source by arranging first and second rotating devices for rotating the lengthy shape steel product by a specified angle from vertical posture to horizontal posture and from horizontal posture to vertical posture, respectively, opposite to each other with a prescribed space, and simultaneously rotating both the rotating devices in opposite directions. SOLUTION: The rotating arm 12 of a first rotating device A is set vertical to push the vertical flange end surfaces of an H-shape steel 1 in vertical posture. At this time, the rotating arm 22 of a second rotating device B is interlockingly rotated 90 deg. and laid into vertical state. When a first rack 32 is driven in the direction shown by a solid line arrow, the pinion 14 of the first rotating device A is rotated 90 deg. on the downstream side to lay the H-shape steel 1 into horizontal state. The rotating arm 22 of the second rotating device B is laid horizontally. The H-shape steel 1 in the horizontal posture of the first rotating device A is pushed into the arm 22 of the second rotating device 2. When the rotating arm 12 of the first rotating device A is set vertical, the pinion 23 is rotated 90 deg. to lay the rotating arm 22 vertical, and the H-shape steel 1 is laid in the vertical posture where the vertical flanges are turned upside down.

2. Description of the Related Art Conventionally, in the case of manufacturing a shaped steel, an H-shaped steel will be described as an example. Generally, most of the H-shaped steel is manufactured by hot rolling. That is, first, a beam blank, which is a raw material of H-section steel, is heated to a predetermined temperature in a heating furnace, and is broken down by a first breakdown rolling mill. Then, it is rolled by a coarse universal rolling mill to a position close to the final product shape. Then, it is rolled to a target size by a finish universal rolling mill and cut into a predetermined length. Further, after being cooled in a cooling bed, the shape is adjusted by a straightening machine or a press and then shipped.

In recent years, the demands of customers have been diversified, and the dimensions, shapes, and appearances have become strict, which has led to advances in manufacturing technology. However, in the manufacturing process, it is not possible to prevent the occurrence of scratches on the conveyance rollers, guides of the conveyance table, transfer skids, etc., and there is a problem that the appearance of the product is impaired. The present condition is to rely on the visual inspection of the operator for the problem of the appearance, and there is a case where the H-shaped steel is rotated to inspect and care for the back surface as necessary.

The conventional means for rotating H-section steel is 90 °
In the case of rotation, as shown in FIG. 7, a flange receiver 52 for mounting the flange surface of the H-section steel 1 is attached and an arm 51 which is rotatable by a rotating shaft 53 is rotated by a lever 54 to 90 °. In general, a turning device called a turner composed of a cylinder 55 is used, and in the case of reversing by 180 °, the riff mag 60 as shown in FIG. 8 is often operated by a crane or the like not shown.

However, among the above-mentioned conventional means, the case of the turner is only 90 ° rotation, so that there is a problem that it cannot be used when the H-section steel is to be inverted to 180 °. Also, in the case of a riff mag, there is a problem that it is necessary to carry out several times of crane lifting and lowering operations in order to invert it to 180 °, which is inefficient and dangerous, and when the H-section steel comes out of the riff mag, it becomes excessive. However, there is a drawback in that it is unfavorable to the environment because it gives a strong impact and simultaneously produces noise.

The present invention has been made to solve the problems of the prior art as described above, in which a long steel material is provided.
It is an object of the present invention to provide a turning device having a simple drive source and a simple structure when rotating 90 ° or reversing 180 °.

Here, the tuning shaft 13 of the first rotating device A, the tuning shaft 37 of the driving device C, the tuning shaft 37 of the driving device C, and the tuning shaft 23 of the second rotating device B are spaced by L, respectively. / 2
However, this distance L / 2 is set to a value slightly longer than the length of the rotary arm 12 or the rotary arm 22. Next, the operation of the turning device 10 of the present invention thus configured will be described with reference to FIG. As shown in FIG. 2 (a), the rotating arm 12 of the first rotating device A is set in the vertical state, and the flange receiving cylinder 16
Of the H-shaped steel 1 in the vertical posture on the skid 2 by the carriage D while the flange receiver 11 is projected.
Push in until the end surfaces of the upper and lower flanges of the contact the rotating arm 12. At this time, the rotary arm 22 of the second rotary device B is also interlocked and rotated 90 ° to be in the vertical state. When the fluid pressure cylinder 31 is actuated to drive the first rack 32 in the direction of the arrow indicated by the solid line as shown in FIG. 2 (b), the pinion 14 of the first rotating device A moves 90 ° downstream. The H-shaped steel 1 is brought into a horizontal posture by rotating the rotating arm 12 in a horizontal state. At this time, the interlocking pinion 38 that operates at the same time
Thus, the pinion 24 of the second rotating device B rotates to the upstream side to bring the rotating arm 22 into a horizontal state. At this time, the flange receiving cylinder 26 of the second rotating device B is operated so that the flange receiving 21 is projected. Then, the carriage D is driven to move the horizontal H-shaped steel 1 on the rotating arm 12 of the first rotating device A onto the rotating arm 22 of the second rotating device B as shown in FIG. 2 (c). Push it in until it hits the bottom of the flange. When the fluid pressure cylinder 31 is operated again and the first rack 32 is driven in the direction of the arrow shown by the dotted line as shown in FIG. 2 (d), the pinion 14 of the first rotating device A moves 90 degrees upstream. °
Rotate the rotating arm 12 to a vertical position. At this time,
The pinion 24 of the second rotating device B is rotated by 90 ° to the downstream side by the interlocking pinion 38 that operates simultaneously, and the rotating arm 22
To the vertical state. As a result, the H-section steel 1 has a vertical posture in which the upper and lower flanges are reversed with respect to the step.
