[Technical field to which the invention belongs]

 In the present invention, when many webs are simultaneously wound on each coaxial core, a pressing roller is always brought into contact with the outer periphery of a take-up roll formed on each core to provide a required contact pressure. The present invention relates to an individual holding roller device. Specifically, the present invention mainly prevents the air from being trapped between the winding layers and forms a neat winding form when, for example, a slitter is used to simultaneously divide a multi-slit web into two axes and wind them at the same time. The present invention relates to each presser roller device for obtaining.

[0002]

[Prior art]

 As each of the individual press roller devices as described above, a oscillating shaft arranged parallel to each winding core, a boss fitted to the oscillating shaft so as to be interlocked with the rotation direction and movably in the axial direction, Boss fixing means for fixing the boss to the swing shaft at a predetermined position on the axis thereof, an arm engaged with the boss at one end, and supported at the other end of the arm via the boss and the arm from the swing shaft. There is already known a pressing roller which is provided with a oscillating power and always comes into contact with the outer periphery of a winding roll on each winding core to give a required contact pressure.

[0003] In each of the individual pressing roller devices, when the width of the winding strip wound around the core is changed, it is necessary to replace the pressing roller with one having a length corresponding to the changed winding strip width. In addition, even if the press roller is not replaced as described above, the position of the winding strip may change, and in any case, it is necessary to move the entire press roller device including the constituent members in the axial direction of the swing shaft. is there.

In each of the known individual pressing roller devices, the swing shaft and the boss are simply loosely fitted. When the device is moved, the axis of the swing shaft is manually moved to the arm or the like while the boss fixing means is unlocked. A directional force is applied, causing the boss to slide on the pivot axis. However, in the above-mentioned loose fitting structure of the swinging shaft and the boss, even when only one of the pair of bosses is slid, it is difficult to move or pry easily, and even more, the pair of bosses are connected to each other. It was extremely difficult, almost impossible, to smoothly slide at the same speed while maintaining the same spacing with the holding roller attached to the arm.

In a case where the individual press roller devices are applied to a slitter, in a usual mode, a take-up roll is disposed on a front surface, a press roller is mounted thereon, and a boss and a swing shaft are disposed deep. In the conventional loose fitting structure, the entire device is moved in the axial direction of the swinging shaft by grasping the front portion of the arm which is easily accessible on the front surface or a pressing roller at the tip of the arm. Was virtually impossible.

Further, in each of the individual press roller devices, each press roller is moved with respect to each winding strip so that the contact pressure of each press roller is uniformly applied to the outer circumference of each winding roll in the width direction of the winding strip. Although it is required to set the center precisely at the position of the center distribution, the conventional loose fitting structure requires a great deal of labor and time for the position adjustment work.

[0007]

[Problems to be solved by the invention]

 In view of the above problems in the prior art, the problem of the present invention is to change not only the width of one winding arm but also the entire device including a pair of arms and a holding roller when changing the width of a winding strip. An object of the present invention is to provide an individual pressing roller device that can be moved lightly, smoothly, and in a short time in the axial direction of a swing shaft.

[0008]

[Means for Solving the Problems]

 Each individual pressing roller device according to the present invention includes a swing shaft arranged in parallel with each winding core, and a boss fitted to the swing shaft so as to be interlocked with the rotation direction and movable in the axial direction. Boss fixing means for fixing the boss to the swing shaft at a predetermined position on the axis thereof, an arm engaged at one end with the boss, and supported at the other end of the arm via the boss and the arm from the swing shaft. In each individual pressing roller device, which is provided with a oscillating power and a pressing roller which always comes into contact with the outer periphery of the take-up roll on each winding core to provide a required contact pressure, a roller is provided on an inner periphery of the boss, and a roller of the oscillating shaft is provided. The boss is disposed at a plurality of positions in the direction of the center angle of the inner periphery of the boss and in the axial direction of the swinging shaft so that the boss can be rolled in contact with the outer periphery and in the axial direction thereof. On the swing axis in the direction of its axis It is characterized in that it has obtained manner.

In the above configuration, the boss is provided on the inner periphery of the oscillating shaft instead of being fitted directly on the oscillating shaft by sliding the inner periphery of the boss directly on the outer periphery of the oscillating shaft. Since a plurality of rollers that can roll in the axial direction are fitted on the rocking shaft by contacting the outer periphery of the rocking shaft, the movement of the boss in the axial direction is performed extremely smoothly.

【Example】

 Hereinafter, the present invention will be described based on an embodiment shown in the drawings. FIG. 1 is a plan view of a partial cross section of each individual pressing roller device according to the embodiment of the present invention as viewed from above, and FIG. 2 is a side view as viewed from the direction of A-A 'in FIG.

In FIG. 1, a plurality of pairs of bosses 2 (only one pair is shown in FIG. 1) formed of an assembly are fitted on a swing shaft 1, and a long arm 3 is mounted on each boss 2. A pressing roller 4 composed of an assembly is supported at the ends of both arms 3 by a known structure.

A knob screw 5 as a boss fixing means is screwed to each boss 2 at the tip thereof so as to be able to come into contact with and separate from the outer periphery of the swing shaft 1. The knob screw 5 is attached to the boss 2 on the swing shaft 1. The boss 2 is loosened when the position is adjusted, and tightened after the adjustment to fix the boss 2 at the required position of the swing shaft 1.

A key 6 is attached to each boss 2 with a bolt 8 while being loosely fitted in a key groove 7 on the swing shaft 1 with a gap therebetween. To Boss 2. The oscillating power transmitted to each boss 2 is transmitted to each arm 3 and the pressing roller 4 via a force transmission section 9 provided between the boss 2 and the arm 3.

On the inner periphery of each boss 2, a roller 10 comes into contact with the outer periphery of the swing shaft 1 at one point of its rotation outer periphery and directs the rotation direction at the contact point to the axial direction of the swing shaft 1. In addition, the boss 2 is disposed so as to be able to rotate very lightly via the pin 11 at three locations in the center angle direction of the inner circumference of the boss 2 and at two locations in the axial direction of the swing shaft 1 at intervals of 120 degrees. The roller 10 only needs to rotate slightly, and for example, a miniature bear ring or the like may be used. In the above case, each boss 2 is formed with an inner diameter slightly larger than the outer diameter of the oscillating shaft 1 so as not to contact the oscillating shaft 1.

In the above configuration, the fixing of the boss 2 to the swing shaft 1 is released by loosening the knob screw 5 on the required boss 2, whereby the boss 2 is connected to the arm 3 or the arm 3 connected thereto. Further, it can be manually moved in the axial direction on the oscillating shaft 1 via the hob 10 integrally with the pressing roller 4 attached thereto.
