[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic separator exchanging device in a slitter line for cutting a strip material such as a rolled steel plate with a predetermined width in a longitudinal direction.

[0002]

2. Description of the Related Art In a slitter line that divides a strip material into a plurality of strips in the width direction, in order to prevent the telescopic winding disorder of the strip strips, the edges of the strip strips are guided to guide the strips. A separator is provided to correct the deviation in the width direction. As shown in FIG. 10, the separator 50 includes a separator shaft 51 whose diameter can be changed by a hydraulic mechanism or a pneumatic mechanism, a plurality of ring-shaped separator rings 52 fitted to the separator shaft 51, and a separator shaft 51. A bearing 53 rotatably supporting both ends is provided, and the spacing of the separate ring 52 is adjusted and held via an annular spacer 54. By contracting / expanding the diameter of the separator shaft 51, the separator ring 52 is slid / fixed with respect to the separator shaft 51. Therefore, the separator ring 52 is moved in the axial direction and cut into a predetermined width. The spacing between the separator rings 52, 52 can be adjusted and fixed according to the width dimension of the strip.

Conventionally, based on the width dimension information of the divided strips,
The distance between the separator rings 52, 52 is set in advance by an operator,
Alternatively, it was adjusted by an automatic machine and then temporarily stored, and after the winding was completed, the slitter line was stopped, and then the separator 50 was transported by a crane or the like and set at the winding position of the strip.

[0004]

However, it takes a considerable amount of time to replace the separator 50 such that the slitter line is stopped, the separator 50 is transported by a crane or the like, and the separator 50 is set at the winding position, which lowers the productivity. There is a problem such as doing.

Further, it cannot be carried out in a line having no storage space for the separator 50, and a separator ring exchanging device (not shown) for changing the interval between the separator rings 52 depending on the type of the separator 50 is installed at the winding position. Although desirable, doing so would make the equipment more complicated and expensive, and would also be disadvantageous in terms of space.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an automatic separator exchanging device capable of efficiently exchanging separators in a slitter line and also saving installation space. And
