For reference, the electrical and electronic circuits used in the device are not shown because they apply known techniques.

In the present invention as described above, the upper body of the steel plate material device portion (A) is superimposed on the upper plate of the holding plate and coupled to the circular bearing, and the rotary gear formed on the rotating shaft of the upper body is engaged with the driving gear of the hydraulic motor to drive the fluid pressure motor. Rotate 180 degrees in the clockwise or counterclockwise direction, and the elastic support shaft 160 is formed on both sides of the upper body. When the coil steel sheet is mounted on the elastic support shaft, the upper body is rotated to rotate the elastic support shaft outward. Coil steel sheet can be fitted to the elastic support shaft from the outside to facilitate the installation of the coil steel sheet, and after the coil steel sheet is mounted, the expansion support shaft can be expanded to keep the support shaft in tension in the center of the coil steel sheet and keep it safe. Stretched support shafts are formed on both sides of the upper body, and two coil steel sheets can be mounted on the upper body. Once this is conveniently so the steel sheet coil device in the steel sheet material has the advantage that the device parts can be thereby returning the body to the original position taking release the outer end of the coil plate added to the steel sheet material feed connection.

In addition, the transfer path of the steel plate material transfer connection part is provided with a steel plate material feed roller 200 on both sides, and side guides 201 are provided on both sides of the transfer path through which the steel plate material moves. It can be transported correctly without being separated, and the electric welding machine (B4) and the electric grinder (B5) are installed on the conveying path so that the tape work can be connected to each other on the conveying table and welded and polished. The material storage supply part is equipped with a winding drum (D1) on the fixed frame so that it can be rotated or paused left and right by a left and right rotating motor, and the winding part is formed on the outer surface of the winding drum so that steel sheet material can be rolled up to be wound. It can be stored by winding steel sheet material of 3 ~ 4 lengths together. The steel sheet wound on the sheet is drawn out from the inner end to the outside through the first roller conveyor (D2) and the spiral roller conveyor (D3) mounted at the center of the winding drum through a drawing part (D100) formed on the inner surface of the winding part. Since the steel sheet material is wound around the winding drum winding part, the action of unwinding the steel sheet material from the inner center to the outside can be performed in parallel, so that the steel sheet material can be supplied while the steel sheet material is consumed. Continuous supply is possible.

On the other hand, when storing the steel sheet material in the winding drum of the present invention by rotating the winding drum clockwise to loosen the outer end of the steel sheet material wound on the outer surface to move to the welding position of the steel sheet material transfer connection (B) and coil steel sheet device The outer end of the steel plate material installed in (A) is unwrapped and moved to the welding position of the steel plate material transfer connection part (B) to operate an electric welder to weld each other, and the weld parts are polished and connected, and then the winding drum is rotated counterclockwise. It is possible to move the coiled steel plate installed on the coiled steel sheet to the outer side of the winding drum by rotating it. When using the steel sheet wound on the outer side of the winding drum, the outer feed roller driving part of the steel plate material is stopped and the inner side of the coiling drum is formed. The steel sheet material is drawn out through a roller conveyor and supplied to the roll forming part for molding. Correspondingly, the winding drum can be slowly rotated clockwise to smoothly pull out the steel plate material. As the winding drum rotates clockwise in this process, the tension history of the steel plate material wound on its outer surface is loosely formed on the roller surface. The steel sheet wound on the winding section by the vertical roller does not deviate from the guide groove and rotates to correspond to the speed supplied to the roll forming section so that it can be safely drawn out and connected to the new steel sheet before the steel sheet wound on the winding drum is consumed. Because it is stored in the winding drum, it is possible to connect the new material and store it before it is consumed by releasing the stored one. Therefore, it is possible to continuously supply the steel sheet material to the roll forming machine due to the repetition of this operation, thereby enabling uninterrupted molding. This makes efficient section steel manufacturing You will get the effect that you can continue to be made.

In particular, in the winding drum (D1) of the present invention, the roller surface is formed in the winding portion and the roller groove is formed so that the steel sheet material wound on the winding portion is smoothly transported when the coiled steel sheet material is wound or unwinded while being pulled out and relaxed. The first roller conveyor (D2) and the spiral roller conveyor (D3) formed from the center and the center of the winding drum (D1) to help the outside and the path of winding the steel sheet material wound on the winding drum and other paths This allows the work to be taken out from the center while winding the material on the winding drum surface, which can achieve the advantages of the invention without inconvenience, and the material guide groove formed on the roll surface is Rotating the four-spin to keep the guide grooves of the width corresponding to the width of the steel plate material as the distance between the mover to increase or narrow Even if the size of steel plate material is changed, it can be used to adjust it. It is possible to adjust the height and height of the flat plate (B34) of the device part. You will get the effect.

Therefore, by using the supply device of the present invention in combination with a known automation circuit, the coiled steel sheet is stored in the device portion (A) and released while being stored in the steel plate material storage supply portion through the transfer connection portion (B) at a speed necessary for molding. Forming operation is possible while dispensing and supplying, so that continuous supply is achieved without interruption of material supply, and continuous molding is possible. The shaped steel is cut to a certain length, preheated to electric preheating furnace (G), and then painted (H) is painted on the surface and transported to the side by the rotary conveying unit (I) in the form of a watermill dried and then conveyed through the conveyor conveying unit (J) and the rotary conveying unit (K) product packaging unit (L) The whole process, which is collected and packed in a certain quantity, can be automated in a single process, which can greatly improve the production efficiency. will be.
