The present invention relates to a band binding device of a coil which finally binds a cold rolled coil produced through a cold rolling process as a band, and more particularly, to prevent problems caused by unwinding the end of the coil during movement of the produced coil. Instead of the normal welding binding, the band is automatically bound by rivets, which effectively prevents coil loosening due to poor operation or poor welding during post-processing due to slag (welding fragments) generated during welding. However, the present invention relates to a band binding device for coils that automatically performs band binding by using rivets, so that the binding and subsequent movement of the coil and the post-processing process can be performed smoothly as a whole.

The cold rolled coil produced through the cold rolling process is easily released because its end is elastically stretched and the coil is difficult to transport in this state. The whole coil is bound, and the usual use is to bind the band.

On the other hand, as shown in Figure 1, the band binding that is conventionally used so far, when the band 100 is wound around the coil through the coil binding machine, by welding the overlapping portion of the band using the welding electrode 110, Band binding was performed.

However, in the case where the binding band of the coil is bound using the welding through such an electrode, the welding occurs because the band is welded on the curved coil as a cause of malfunction in the post-process due to the slag generated during welding. There was a problem that the loosening of the end of the coil due to a defect easily occurs.

That is, as shown in FIG. 2A, slag S (welding fragments) generated during welding for binding the band 100 of the coil C is attached to the coil surface, and such slag S is shown in FIG. 2B. As shown in Figure 5, the post process of the coil, for example, is attached to the surface of the rolling roll (120) during rolling is transferred to the coil (D), which degrades the quality of the coil (C).

Or, when the band 100 of the coil (C) through the conventional welding there is no way to check the welding state of the welding is not performed properly, if the movement of the coil is made in the state of poor welding, Figure 3a or Figure As shown in 3b, the end C ′ of the coil C is released when the mobile car 130 and the moving crane 140 move.

In this case, if the movement of the coil C is performed while the end C 'of the coil is loosened, it may interfere with the trolley wire of the crane to generate an electrical problem or collide with the equipment such as the skid and the mobile car 130. (Interference) crushes the end of the coil and causes a fault in the post-process.

In particular, in recent years, the use of automobile exterior materials that require high quality as the use is increased, even small defects are not allowed, which is a situation in which coil defects are often caused by welding slag generated during spot welding of the band normally.

Accordingly, in view of the fact that welding slag is generated during the binding of the coil and loosening of the end of the coil due to the welding failure due to the difficulty in checking the welding state, the binding state is also solid without the welding slag occurring during the binding of the coil. There has been a need for a technique for band binding of coils using rivets.

The present invention is to solve the conventional problems as described above, in place of the conventional band binding of the coil to prevent the problems caused by unwinding the end of the coil during movement of the produced coil, instead of the conventional welding bond, using a band using a rivet By automatically binding, it is possible to effectively prevent various problems caused by welding slag in the post-process by welding slag or coil loosening due to welding failure, as well as by using the rivet but automatically band bonding to bond the coil and It is an object of the present invention to provide a band binding device for coils using rivets to smoothly perform the movement afterwards and the post-treatment process as a whole.

As a technical configuration for achieving the above object, the present invention is connected to the band supply and installed to move up to the center of the coil, the device frame unit including a band guide for implementing the loop of the band; And,
