BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slitter winding device which cuts a wide sheet into a plurality of narrow sheets and winds the sheet.

[0002] Generally, when a wide sheet material such as a synthetic resin film, paper, aluminum foil or the like is cut into a plurality of narrow sheet materials and wound, it is described in, for example, JP-A-61-18662. As described above, a slitter is used in which a winding device for winding a sheet material cut into a predetermined narrow width is installed in a state of being opposed to each other with a touch roller for applying surface pressure therebetween. Such a winding device is disclosed in, for example,
A winding shaft for tightening a plurality of cores is provided on one shaft body as described in JP-A-1-18662. When tightening an empty core on the reel, a mark indicating the end face position of each core is marked on the peripheral surface of the reel with magic ink or the like, and an operator visually aligns the end face of the core with the mark. I have. In such a method, the positioning operation takes a long time, and an error of about 1 mm occurs even if the positioning operation is performed with care. Further, when the sheet width changes, a mark indicating a new position needs to be specified so as not to make a mistake each time. Further, there is a problem that the positioning mark disappears when the core is attached and detached several times.

[0003] Therefore, it has been attempted to install a positioning mechanism as shown in FIGS. The configuration of this positioning mechanism will be described. A rod 21 is rotatably installed in parallel with the winding shaft 20, and a positioning member 22 is attached to the rod 21 so as to be movable in the longitudinal direction of the axis. The core 50 is located at a position away from the winding shaft 20.
Is supplied to the winding shaft 20, and each core 50 is inserted into the vicinity of the positioning. Next, the rod 21 is rotated by a fluid cylinder (not shown) or the like to move the positioning member 22 to the winding shaft 2.
0 abuts on the peripheral surface. In this state, each core 50 is brought into contact with the positioning member 22 to perform positioning, and a tightening mechanism (not shown) is operated to integrally tighten each core 50 to the winding shaft 20. In such a positioning mechanism, when the winding diameter of the sheet-like material becomes large, the positioning member 22 becomes long and deforms unless it has a rigid shape, so that there has been a problem that positioning accuracy is deteriorated.

[0004]

The first problem is that the positioning operation takes a long time, and an error occurs even if the positioning operation is performed with care, so that an error is not made each time the sheet width changes. It is necessary to specify a mark indicating a new position, and the positioning mark disappears when the core is detached and attached several times.

[0005] A second problem is that the positioning accuracy deteriorates as the winding diameter of the sheet-like material increases.

[0006]

In order to solve the first problem and the second problem, a winding device for a slitter according to the present invention is provided at a position near the winding shaft. A positioning mechanism for determining a tightening position of each of the mounted cores is provided, and a plurality of positioning members are mounted on the positioning mechanism so as to be movable in a longitudinal direction of the axis, and the positioning member is positioned close to the winding shaft. Rotatably installed on the machine frame so as to separate
And a spacing member attached to the machine frame or the rod so that a predetermined spacing is formed when the positioning member approaches the winding shaft. Moreover, the spacing member such as according to claim 2, formed by a cylindrical member, a configuration was allowed mounted on rods, the spacing members, such as claim 3, in the configuration in which is screwed a screw member for the stopper to the bracket , The arm is said
It is also possible to adopt a configuration in which it is mounted on the machine frame so as to abut on the screw body for the stopper .
