[Prior art]
2. Description of the Related Art Conventionally, as a reversing device for a shaped steel material for reversing a long shaped steel material for cooling, inspection, and stacking of the shaped steel material after rolling, a device described in JP-A-1-127518 is known. In the reversing device of the shape steel material of the form described in this gazette, on the rotating body rotatably attached to the carriage that runs on the frame, the mounted shape steel (implemented when rotated 90 °) In the example, the steel sheet pile has a receiving arm that is inclined in advance by an angle necessary to invert and fall due to its own weight, and a support arm that supports a side edge serving as a pivotal fulcrum of the section steel. In addition, a receiving arm is attached to the traveling carriage so that it can freely rotate. After the steel frame that is inverted and overturned is received by the receiving arm in the middle of the inversion, the steel frame is inverted and overturned by the rotation return operation. The rotating body and the receiving arm are rotated with respect to the carriage by using the traveling movement operation of the carriage with respect to the frame. Therefore, the shape steel can be reversed with a small rotation operation in conjunction with the traveling of the carriage.

FIG.
As shown in FIG.1 and FIG.2, the reversing apparatus 10 of the shaped steel material which concerns on one embodiment of this invention, the inclination type conveyor 12 which is an example of the conveying apparatus arrange | positioned in the upstream of the rear surface apparatus 11, and an inclination An inlet conveyor 14 that is an example of a supply device that is disposed on the upstream side of the conveyor 12 and that supplies a long channel steel 13 that is an example of a shape steel to the inclined conveyor 12 and is inclined at a predetermined inclination angle. It has a shape steel material reversing mechanism 15 for reversing the reversing grooved steel 13 which is supplied to the inclined conveyor 12 from the entrance conveyor 14 by natural fall. Hereinafter, these structures and the method of conveying and reversing the channel steel 13 will be described in detail.
[0007]
The inlet-side conveyor 14 is configured by a plurality of headless drive sprockets 16 and a tail-side driven sprocket (not shown) spanning a plurality of rows of endless roller chains 17. The driven sprockets on the tail side and the tail side are mechanically driven synchronously so that the long (for example, 6 to 24 m) channel steel 13 can be conveyed in parallel without being inclined in the traveling direction.
The inclined conveyor 12 is a short conveyor capable of transporting one channel steel 13, and like the entrance conveyor 14, a plurality of rows of drive sprockets 18 on the head side and driven sprockets 19 on the tail side are arranged in a plurality of rows. The endless roller chain 20 is stretched over. When the inclined conveyor 12 is horizontal, as shown in FIG. 1, the channel steel 13 conveyed by the entrance conveyor 14 with the opening 21 after the rolling facing downward is maintained in the horizontal conveyance state. The second conveyance of the endless roller chain 20 and the first conveyance surface 17a of the endless roller chain 17 so that the transfer can be transferred to the inclined conveyor 12 and horizontally transferred to the downstream rear surface device 11.

As shown in FIG. 2B, the grooved steel 13 having the bottom portion 13c placed on the placement surface 23a is tilted by the driving of the conveyor tilting mechanism 22 with the inclined conveyor 12 having the center A of the drive sprocket 18 as the rotation axis. After being placed and raised on the second transport surface 20a, it becomes the original horizontal state as shown in FIG. 2C, and then drives the endless roller chain 20 of the inclined conveyor 12, The channel steel 13 is transferred to the rear surface device 11 and conveyed. The grooved steel 13 is stopped by a stopper 25 provided on the rear surface device 11, and is conveyed from the lower surface of the grooved steel 13 to a predetermined place from the rear surface device 11 by the lift means 26, and the rear surface of the grooved steel 13 (FIG. 2 ( The state shown in B) and (C)), inspection or stacking will be carried out.
[0011]
Therefore, as shown in FIG. 1, the grooved steel 13 conveyed to the rear surface device 11 with the bottom 13c after the end of rolling as an upper portion, and on the other hand, as shown in FIG. The grooved steel 13 conveyed to the rear surface device 11 with the bottom 13c at the bottom by the height position adjusting mechanism 23 and the shaped steel material reversing mechanism 15 is alternately placed at a predetermined location by a lifting means 26 at a predetermined conveying interval. As shown in FIG. 3 (A), the first stage stacking can be performed by arranging the opening portions 21 of the channel steel 13 so as to face each other, and the upper surface 27 of the first stage stacking can be performed. The second and opposite channel steels 13 can be stacked on the continuous bottom 13c of the channel steels 13 arranged at the same level.
In addition, although the grooved steel 13 was demonstrated as a shape steel material handled, also in the case of the angle steel 28, as shown in FIG.8 and FIG.9, it is similarly conveyed or reversed, and as shown in FIG.3 (B). Can be stacked.

While the upper end of the steel 28 is in contact with the upper surface of the drop guide main body 76 of the shape steel material drop guide 32, the reversing lever 24 performs the reversal. On the other hand, in the case of the small angle steel 28a, the fall height adjusting carriage 75 is advanced. As shown in the figure, the reversing lever 24 causes the lower end of the angle steel 28a to contact the lower portion of the resin material 74 and the upper end of the angle steel 28a to contact the upper surface of the drop guide body 76 of the shape steel material drop guide 32. Inversion can be performed.
Therefore, regardless of the size and shape of the shape steel material, the posture after the free fall of the shape steel material can be properly maintained before reversal.
[0019]
In the said embodiment, although the entrance side conveyor 14 was demonstrated as a supply apparatus, it is not limited to this, For example, pushing the shape steel material on the roller table conveyed on the fixed skid or the orthogonal direction, such as a pusher You may fall naturally to the inclination type conveyor 12 using an apparatus.
Further, the inclined conveyor 12 tilts the driven sprocket 19 side with the drive sprocket 18 side as the center of rotation, but is not limited to this, and the entire conveyor can be raised and lowered. Moreover, although demonstrated as a roller chain system, while providing the skid which can be rotated, pushing devices, such as a pusher, which conveys the shape steel material reversed on the skid to a rear surface apparatus can also be provided.
The drop height position adjustment mechanism 23 allows the drop height adjustment carriage 75 to move forward and backward in the horizontal direction, but can also move in the vertical direction to the second transport surface 30 a of the inclined roller chain conveyor 30. Moreover, the shape of the upper surface of the drop guide main body 76 that guides the posture of the falling shape steel material is selected to have an optimum shape for the various shape steel materials to be handled.
[0020]
In the above-described embodiment, the shape steel material reversing mechanism 15 and the drop height position adjusting mechanism 23 are separated from the inclined conveyor 12 and attached to the attachment frame 44 separately, but are attached to the inclined conveyor as necessary. You can also.
The supply and conveyance posture of the channel steel 13 has been described in the state where the opening 21 is on the lower side, but the state in which the opening 21 is on the upper side may be reversed.
As the shape steel material, the groove shape steel 13 and the angle steel 28 have been described. However, if the drop height position adjusting mechanism 23 is determined according to the use conditions, it can be applied to other shape steel materials such as a steel sheet pile. .
Although the conveyance surface of the entrance conveyor 14 and the rear surface device 11 is horizontal, the conveyance surface may be slightly inclined within the range of the frictional resistance between the shaped steel material and the conveyance surface.
