While supporting on the supporting surface, the upper end edge side of the supporting wall portion, which is opposed to the base end edge as a rotation axis, is aligned with the base in the same direction as the rotation direction of the base. For reversing by moving, stably inverted without the inversion object is overturned during inversion.

Next, the operation of the above embodiment will be described.

For example, in the production of welded T / H section steel,
When inverting a material 23 that is an object to be inverted, in which a steel material 21 that is a slender plate-shaped flange material and a steel material 22 that is a corrugated material are joined substantially vertically by welding, a base 32 is first held. The surface 33 is positioned so as to be substantially horizontal, the support wall portion 12 is positioned so that the support surface 18 is substantially vertical, and the pedestal portion 4 is provided.
The base 32 is placed between the free rollers 8 and 8, that is, in the standby state in which the center line of the base 32 is located on the center line of the manufacturing line.

Then, by means of a conveyer such as a conveyor (not shown), the material 23 in which the steel materials 21 and 22 are joined in a substantially T-shape by welding is conveyed onto the free rollers 8 and 8 and carried onto the base 32. To do. When carrying in the material 23, a steel material 22 as a wave material is carried in by a centering device (not shown) while being positioned on the center line of the manufacturing line, and one edge of the steel material 21 as a flange material is a supporting wall portion. The pair of liners 17, 12 is in contact with the base end side of the support surface 18, which is the surface.

In this state, the rotating means 34 is driven to drive the base.
Rotate 32. By the rotation of the base 32, the material 23 is lifted, and one side surface of the steel material 22 serving as the corrugated material of the material 23 rotates toward the upper end edge of the support wall portion 12. Then, immediately before one side surface of the material 23 comes into contact with the upper end edge of the support wall portion 12, one side surface of the material 23 comes into contact with the detection portion 25 of the detection means 24,
The detection unit 25 moves so as to be pushed back from the support surfaces 18 of the pair of liners 17 and 17 so as to retreat, and a sensor (not shown) is used as a material.
The rotation of 23 is detected. The material 23 of this detection means 24 is the supporting surface
Upon detection of the contact with 18, the control means (not shown) stops driving the rotating means 34 and drives the driving means 16.

By the drive of the drive means 16, the rotating means 34
Is provided between the support wall 12 and the base 32, and the drive means 16 is provided between the pedestal 4 and the support wall 12 that support the support wall 12 and the base 32. Support surface 18
The support wall 12 and the base 32 rotate substantially integrally while holding the material 23 without changing the size of the angle formed between the support surface 12 and the holding surface 33 of the base 32.

Then, the material 23 is stably inverted by the substantially integral rotation of the support wall 12 and the base 32, and the tip of the steel material 22 serving as the corrugated material of the material 23 is supported by the frame body 2. ,
The reversal is complete.

According to the above-described embodiment, since the base 32 on which the material 23 is placed is rotated and supported by the support wall 12, the support wall 12 is rotated together with the base 32. Even when the material 23 is overturned, it can be stably held and inverted without overturning, and damage to the base 32, the support wall portion 12, the frame 2 and the pedestal portion 4 and the like due to the overturn and the material 23 can be prevented. .

Further, in the conventional reversing apparatus using the pedestal having the L-shaped integral structure of the base and the supporting wall portion, for example, when reversing the T-shaped steel, the width direction of the steel material 22 serving as the wave material is changed. In order to invert it to a position that is substantially horizontal, a member that supports the steel material 22 that serves as a corrugated material, such as a spacer, is separately required in the portion that serves as the support wall portion. Since the material 23 is held by the base 32 and the support wall 12 in a state of being expanded in a letter shape, the base is in a state in which the width direction of the steel material 22 serving as the corrugated material is positioned in a substantially horizontal direction. Only by stopping the rotation of 32 and the support wall 12,
It does not require a separate spacer, etc., and can handle a variety of inversion situations with a simple structure.

The base with the holding surface 33 that is easy to move along the substantially horizontal direction
Since the support wall portion 12 is positioned in a substantially vertical direction in which the support surface 18 is substantially perpendicular to the support surface 32, the material 23 that rotates with the rotation of the base 32 does not surely roll over and the support wall portion 12 does not roll over. It is supported by 12, and the material 23 can be reliably inverted with a simple structure.

Further, a material which rotates with the rotation of the base 32.
Since the detection means 24 for detecting that the 23 has contacted the support surface 18 of the support wall portion 12 is provided, the material 23 is the base 32 and the support wall portion.
It is possible to prevent it from being damaged by being sandwiched between 12 and the material 23 or the base.
No stress is applied to the support member 32 and the support wall portion 12, and it is possible to easily control the driving and stopping of the rotating means 34 and the driving means 16, and the material 23 can be stably and smoothly inverted.

In the above embodiment, the welding T.

Inversions can be targeted.

Although the holding surface 33 of the base 32 is substantially horizontal and the support surface 18 of the support wall 12 is substantially vertical, the stand-by state is set. When the base 32 and the support wall portion 12 are rotated to rotate the base 32 and the material 23 comes into contact with the support surface 18 of the support wall portion 12 as the base 32 rotates, the material 23 is removed. It can also be in an inclined state that does not roll over.

On the other hand, when the material 23 is large, for example, the width direction of the steel material 22 which is a corrugated material is wide and the material 23 protrudes from the frame body 2 when inverted, the base 32 and the support wall portion 12 Before rotating, the moving means 10 is driven to move the pedestal portion 4 to the side opposite to the side to be inverted and then inverted. With this configuration, it is possible to prevent the material 23 from coming into contact with a portion near the reversing device main body 1 during reversing, and to stabilize the material.
You can flip 23. Further, since the pedestal portion 4 is movable, even if the width dimension of the steel material 21 serving as the flange material is different, the distance from the center line of the manufacturing line to the support surface 18 of the support wall portion 12 is the steel material 22 serving as the corrugated material. The pedestal part 4 is arranged so that the distance from the base end part of the
By moving, the material 23 can be easily carried in and the versatility can be improved.

Further, by providing a plurality of pairs of free rollers 8 for loading and unloading the material 23 on the frame body 2, even if there are a plurality of production lines, the base 32 and the support wall portion 12 are provided.
Can move integrally, that is, the base 32 and the support wall 12
Since the pedestal portion 4 supporting the pedestal is movable, by moving the pedestal portion in accordance with the carry-in and carry-out line,
It is possible to easily invert the material 23 that is transported on a plurality of manufacturing lines, and further improve versatility. The rail part 3
The structure is not limited to being movable above, but may be movable vertically.

Further, although the supporting wall portion 12 is described as being formed in a substantially rectangular tube shape, the supporting surface 18 capable of supporting the material 23 which rotates with the rotation of the base 32, such as a plate-shaped member, is provided. It can be any structure that is formed. Further, the base 32 is also formed with a structure having a pair of holding liners 30, 30, but any structure such as a plate-like material on which the material 23 to be carried can be placed can be used.

Although the rotating means 34 for rotating the base 32 is provided between the support wall portions 12 in the above description, for example, the rotating means 34 is provided on the pedestal portion 4 to rotate the support wall portion 12. The structure may be separately rotated.

Further, the structure for rotating the support wall portion 12 and the base 32 is not limited to the hydraulic cylinder, and any structure such as rotating the gear by driving an electric motor may be used.

Further, the explanation has been made by rotating the base 32 and the support wall 12 substantially automatically by the control means. However, for example, the handle may be manually rotated to rotate the support wall 12 and the base 32. You may invert it.
