FIG. 1 shows the structure of a rotating member and the like used in carrying out the method for changing the attitude of an angle member according to the present invention.
Is a plurality of rotating members provided at predetermined intervals in the axial direction. The rotating shaft 2 is supported by bearings 3 and is rotatable. The rotating member 1 is provided with a plurality of protrusions 5 in a radial direction from the center of rotation, and a first mounting portion 6 and a second mounting portion 7 are sequentially provided on the side surfaces in the rotation direction of the protrusions 5 from the tip. It is formed continuously. The first placing portion 6 is capable of receiving and placing the angle material W conveyed by the conveyor 8 installed at a horizontal position on one side in the rotation direction of the rotating member 1 at a position slightly past the horizontal position, The second mounting portion 7 extends upward at a predetermined angle (approximately 20 ° in the drawing) toward the center of rotation when the first mounting portion 6 is oriented horizontally, and the length thereof is equal to the length of one side of the angle material W. It is longer than it is.

The connecting member between the first mounting portion 6 and the second mounting portion 7 has one side standing upright and the angle material W mounted on the first mounting portion 6.
A first step 9 for positioning the corners of both sides of the angle material W is provided at an end of the second mounting portion 7 opposite to the first mounting portion 6. A second step 10 is provided. If the first and second mounting portions 6 and 7 are formed particularly as hardened steel attachments, it is effective for wear and the like.

Reference numeral 11 denotes a receiving stand for the angle member W installed at a horizontal position on the other side in the rotation direction of the rotating member 1, and 12 denotes a conveyor provided adjacent to the receiving member 11 for receiving the angle member W received by the receiving stand 11. 13 is an extruding member that moves from a solid line position to a chain line position to extrude and transfer. In order to avoid the next angle member W, the rotating member 1 is rotated while the angle member W is being mounted on the first mounting portion 6, that is, at an angle θ (about
50 °) will rotate faster than after that.

The change of the attitude of the angle member W using the rotating member 1 will be described with reference to FIG. After the angle member W is conveyed from the previous step on the conveyor 8 with one side standing upright and stopped at a predetermined position where the corners abut on the conveyor flange 8a, the rotating member 1 rotates. Then, when the first mounting portion 6 of the protruding portion 5 of the rotating member 1 is slightly past the horizontal position in FIG. 1, the angle member W is received and mounted by the mounting portion 6. Next, when the rotating member 1 further rotates, the angle member W slides on the first placing portion 6 by its own weight, and the corner portion comes into contact with the first step portion 9 (FIG. 2).

Next, as the rotating member 1 further rotates, one side of the angle material W falls down onto the second mounting portion 7,
In addition, it slides on the first placing portion 7 by its own weight, and its leading end comes into contact with the second step portion 10 (FIG. 3).

Next, the angle member W is further rotated by the rotation of the rotating member 1, as shown by a chain line in FIG.
Pivots around the tip of one side that abuts on the fulcrum, and falls onto the receiving table 11 (FIG. 4).

As described above, the angle W is rotated by 225 degrees from the conveyor 8 on one side to the receiving table 11 on the other side in one rotation of the rotating member 1 to change the posture.

The angled material W whose posture has been changed is then extruded by an extruding member and transferred onto a conveyor 13.
It will be conveyed to a post process.

Such a change in the attitude of the angle member W is performed three times in number of the protruding portions 5 per rotation of the rotating member 1.
