"A rotary brush with a copying roller is installed in an apron connected to the polishing room via a frame that can move up and down so that the brush tip reaches the product passage, and the rotary brush is used to carry out shots. A shot removing device provided with a screw conveyor and an air nozzle for shot blowback is disclosed.However, since such a shot removing device is designed such that the copying roller rides on the product to be processed, The application is limited when an equal plate material is used as a product to be processed, and H-section steel or the like cannot be processed. Further, in this prior art, it is only the screw conveyor that carries out the shots removed from the product, and the shot blowback air nozzle directs the shots remaining on the product passing through the rotary brush toward the rotary brush, that is, Since it blows back against the moving direction of the product and the shot remaining on it, there is a contradiction in the flow of shots, and the ability to remove and clean shots is unsatisfactory.

よび人員が必要となる。With respect to products to be treated such as H-section steel and I-section steel, shots remaining on the product to be treated are removed and cleaned after the scouring work (shot blasting work etc.) to recover the shots. Therefore, in the past, H-section steel (the difference between H-section steel and I-section steel lies in the dimensional ratio of the web and the flange,
Hereinafter, the term "H-section steel" shall be used in the sense including the I-section steel), in order to minimize the residual of shots on the product to be processed, the web of the H-section steel is made vertical. I went with it arranged. However, in the processing line before and after the shot blasting work of H-section steel, cutting,
Hole processing and the like are performed with the web horizontally arranged. Therefore, a reversing device and personnel are required for reversing the H-section steel web 90 ° from vertical to horizontal before the shot operation and reversing from horizontal to vertical after the shot blasting operation.

る。When performing the shot blasting operation with the H-section steel web horizontally arranged, the shot is blown off from the product to be processed by blowing air to the product to be processed using a blower having a high pressure and a large capacity. However, in order to collect dust inside the shot blow-off device, a blower for dust collection with a larger capacity than that for spraying is required, and nonetheless, in any performance of removal, cleaning, and collection of shots. I was totally dissatisfied. In particular, in the case of an extremely long and long H-section steel, the shot is thickly deposited and the shot cannot be completely removed.

シに対するブラシ刷毛植込み密度等が影響する。The rotating brush 9 rotates so that its lower part moves in a direction opposite to the conveying direction of the product 1, contacts the product 1 and sweeps the shot toward the screw conveyor 10.
Shot removal and cleaning effects of the rotating brush include brush brush material, size, elasticity, vertical position of the rotating brush with respect to the product (which defines the pressing force of the brush with respect to the product), and rotating speed of the rotating brush. (The relative speed of the brush brush with respect to the product will be regulated), the brush brush implantation density with respect to the rotating brush, etc. will influence.

ボスの長手方向に延在している。As shown in FIG. 3, the rotary brush 9 is a brush mounting boss 14 in which replaceable radial brushes 15 are planted. A brush implanting member 50 extends in the longitudinal direction of the brush mounting boss at regular intervals in the outer circumference of the brush mounting boss.

To be made. The shaft 12 is attached to a slide base 17 which is slidable with respect to the guide bar 16 via a bearing, is connected to an elevating device 18 via a chain, and is lifted by being guided by the guide bar 16 by the operation of the elevating device 18. .

い。刷毛の断面直径は、１．０〜３．０mmの範囲とする
が、２．０mm程度が好ましい。The brush is made of a resin such as nylon, polycarbonate or polypropylene. Materials with higher tensile strength have better wear resistance and longer life, but are more expensive. The cross-sectional diameter of the brush is in the range of 1.0 to 3.0 mm, preferably about 2.0 mm.

い。又、刷毛の長手方向の形状は、直線形よりも波形加
工した比較的屈曲に耐え易い形状が良い。In order to sweep away the shot, the brush must have appropriate flexibility and elasticity. This also affects the relationship between brush length and cross section. It is desirable that the cross-section of the brush has a higher second moment of area, such as a cross, than a circle. Further, the shape of the brush in the longitudinal direction is preferably a shape which is corrugated and relatively easy to withstand bending, rather than a straight shape.

ェブ面８に接触する位置よりやや下降した位置に回転ブ
ラシ９の上下方向位置を設定する。The tip of the brush 15 is H on the rotating brush 9.
In order to utilize the elasticity of the brush to contact the horizontal web surface 8 of the shaped steel and further scatter the shot, the vertical position of the rotating brush 9 is slightly lower than the position where the brush tip contacts the web surface 8. To set.
【００１５】回転ブラシ９の回転数はＨ形鋼の送り速度

が高速であればショットは激しく飛散するので、刷毛の
仕様に合わせて適宜の回転数を選択するが、２０〜８０
rpm の範囲が良く、３０〜５０rpm でショット除去効果
が特に高いことがわかった。Since the rotational speed of the rotary brush 9 is very large as compared with the feed rate of the H-section steel, it can be determined by ignoring the feed rate of the H-section steel. If the rotation speed of the rotary brush 9 is low, the scattering of shots due to the repulsion of the brush is low, and if the rotation speed is high, the shots scatter violently. Therefore, an appropriate number of rotations is selected according to the specifications of the brush. ~ 80
It was found that the range of rpm was good, and the shot removing effect was particularly high at 30 to 50 rpm.

当である。As described above, the brushes of the rotary brush 9 are not uniformly planted on the entire circumference of the boss 14, and the brushes are planted on the planting members 50 provided at equal intervals in the circumferential direction. The spacing of the implant members 50 in the circumferential direction is 20 ° in the embodiment of FIG. 3, and the number of implant members 50 is 18. The reason why the implanting members 50 are provided at intervals as described above is to enhance the resilience of the brush. If the brushes are densely planted in the circumferential direction, it is not preferable because free elastic bending of the brushes is hindered and friction between the brushes increases. The number of the implanting members 50 arranged on the circumference of the boss 14 is suitably 10 to 30.

動により、回転ブラシ９と同様に昇降する。The shots swept away by the rotary brush 9 fly toward the screw conveyor 10 arranged at a position (right side in FIG. 1) facing the rotation direction of the lower portion of the rotary brush. In order to enhance the effect of collecting shots, a lip plate 19 extends downward from a trough that surrounds the lower side of the screw conveyor 10 in the circumferential direction, and its tip has flexibility and both vertical flanges of H-section steel. It is designed to come into contact with the upper edge of the. As shown in FIG. 4, the screw conveyor 10 is rotated by the rotary drive device 20 and has symmetrical screws to transport the shot from the center to the left and right. The shots transported left and right by the screw conveyor 10 fall downward from the left and right collection ports 21 and 21 'and are collected. The screw conveyor 10 is connected to the elevating device 22 via a chain, and as the elevating device 22 operates, moves up and down like the rotating brush 9.
