Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a section steel rolling facility, and more particularly to a piling device for rolled section steel.

Conventional machines for combining rolled steel sections are equipped with an arm equipped with an electromagnet at the bottom of the conveyor, and the electromagnet attracts the sections to be assembled among the sections flowing onto the conveyor, and the arm is rotated. , a method in which the sections are combined by inverting them and placing them again on top of the section on the conveyor, and a method of combining the sections by reversing the sections on the conveyor, and a method that uses a stacking sheet that reciprocates at right angles on the elevator platform. The stacking sheet advances onto the section steel that has already been piled above, and the section steel to be piled next is transferred on top of it, so by pulling the stacking sheet, the section steel is There is a method in which they are combined in sequence and piled at the same time.

The former has the disadvantage of generating residual magnetism in the shaped steel because it uses a large number of electromagnets, and the latter has the disadvantage that when pulling the stacking sheets,
There are drawbacks such as noise and damage to the material.

The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to reduce noise and noise.
The present invention provides a piling device for section steel that eliminates damage to materials and maintains safety.

That is, in the present invention, a plurality of rolled steel sections are rotated while being held by an arm with a stopper, and the section steel on the arm rests on the stopper at a position rotated by 90 degrees, but the position of this stopper is determined in advance. By adjusting so that both sections fit together, the arm of both sections will be 9.
They are combined when rotated by 0°.

Since the sections assembled in this way are placed on the transfer device while being held by the arms, they may cause noise, damage to the materials, and fall of the combined materials when placed on the transfer device. etc., can be prevented.

Hereinafter, the present invention will be described with reference to illustrated embodiments.

The rolled steel section is cooled in a cooling bed, as shown in the general view in FIG. 1, and then conveyed to the cooling bed outlet cheeple 1.

From this cooling bed outlet cheeple 1, the first plurality of tubes are shifted to the table 2 by a transfer 3.

Next, the same number of rolled steel sections as those shifted to table 2 are transported to table 4.

The rolled steel sections on the respective tables are stopped on the tables 2 and 4 by lifting stoppers 5.

After the rolled steel section has stopped, when the arm 10 provided at the lower part of the rollers of the table 2 and table 4 is rotated as shown in FIGS. 2 to 5 via the motor 11 and reducer 12, the upper surface of the table roller The rolled section steel is lifted by the arm 10.

When lifting, a stopper 17 that is adjustable on the fulcrum side of the arm 10 is used to prevent the rolled steel section from slipping off, and to adjust the shape so that the steel sections on the arm 10 fit together. , both arms 10 to 9
When rotated by 0°, the rolled sections are automatically assembled.

In order to place the assembled rolled steel sections again, the motor 12 that is driving the arm 10 on the table 2 side is rotated in the reverse direction, and the motor 12 that is driving the arm 10 on the opposite side is rotated in the forward direction. The arm 10 further rotates toward the table 2 side on which it is placed.

The rotation angle of the arm 10 of the combined rolled steel section is 90
At a point about 200 past 0, the combination is completed, and
It is held only by the arm 10 on the side of the table 2 on which it is placed again.

At this point, the arm drive motor 12 is reversed so that the arm 10 on the side opposite to the device table 4 returns to its original position.

On the other hand, the arm 10 holding the rolled steel sections rotates at low speed and places the combined rolled steel sections on the table 2.

After placing the rolled steel section on the table, the arm 10 is further lowered to the lower surface of the table 2.

Next, when the table 2 is driven, the rolled steel section is transported to the table 7 and pushed onto the stacking table B by the pusher 9.

The stacking table 8 stacks the combined shaped steel by the arm 10 by lowering the combined shaped steel by the thickness thereof using a well-known elevating mechanism.

When it is necessary to change the distance between the supporting points of the arm 10 depending on the size of the rolled material, the shift cylinder 15 can be used to change the distance between the supporting points of the arm 10.
The structure allows the complete device according to the present invention to be moved, and the position of the stopper 11 can also be adjusted in the longitudinal direction of the arm by turning the nut 18 of the stopper 17 as shown in FIG. 6 or 7.

As is clear from the above description, according to the present invention, it is possible to pile a section steel with a simple mechanism, and it is also possible to perform piling with less damage to the section steel and less noise.

In the above embodiment, an example was shown in which U-shaped steel is piled, but it goes without saying that the present invention can be applied to almost all shaped steel, such as H-shaped and ■-shaped.
