Description

[Detailed description of the invention]

The present invention relates to a separator guide for slit coils, which has a roller guide whose width can be adjusted to separate the metal strip after slitting, and a guide roller which can center the metal strip. Narrow metal strips are produced as narrow coils by being slit from a wide metal strip by a slitter on a slitter line, then wound on a tension reel, but the metal strip itself has a crown. Therefore, when this is divided into multiple strips using a slitter, each strip of metal strip tends to move toward the center of the line, that is, the center of the metal strip before division. In this case, between the slitter and the tension reel, the divided metal strips may interfere with each other and cause scratches or poor winding, so the distance between each strip should be kept constant. need to be kept. Conventionally, a separator guide in which a rotating disk guide is attached to an air shaft has been used as a means for this purpose. It has a structure that separates the bands, making it easy to set their positions, but this alone is not enough to prevent the board from running out.
For thin metal strips, the metal strip has a weak stiffness, so the edges of the metal strip are scratched by the rotating disk guide.For thick metal strips, the metal strip has strong stiffness, so the force in the thrust direction from the metal strip is applied to the rotating disk. As a result, the position of the rotating disc guide deviates from its initial setting position, causing poor winding of the coil. Therefore, it is necessary to prevent the metal strip from meandering, that is, to prevent the thrust force on the metal strip from increasing, and at the same time to prevent the rotating disk guide from shifting even when thrust force is applied.However, conventional separator guides was inadequate in this respect. Fig. 1 is a side view showing the installed state of a conventional separator guide for slit coils, Fig. 2 is a partially cutaway side view of a conventional separator guide for slit coils, and Figs. 3 and 4 are A-A in Fig. 2.
