DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a process for continuously forming a web, in which a wide web is slit into a plurality of webs in the width direction, and the plurality of slit webs are wound into individual windings corresponding to the number of slits. The present invention relates to a multi-axis winding device of a slit device for winding around a winding shaft.

[0002]

2. Description of the Related Art Conventionally, in the winding process of a slitting device, usually, in a process of continuously forming a wide web, a two-axis turret type winding machine is used as a raw material without slitting. It is common practice to unwind the wound web with a slitting device, slit it into a plurality of pieces in the width direction, and rewind.In this case, each winding of the slit narrow width web has a number of slits on one axis. The winding is performed by arranging the individual winding cores in a row corresponding to the above.

[0003]

However, as described above, a single-shaft multi-cavity in which each of the slit narrow webs is wound on individual cores arranged in a row on a single axis has a width of the original web. When the number of slits is relatively small, the problem does not occur so much. However, when the width of the raw web is increased, the number of slits is increased, and the number of multi-pieces is increased, a single reel is used. In the middle part, bending occurs, and when this gradually increases, vibrations occur, which makes winding difficult, and also causes unevenness in the tension of the individually wound web, resulting in deterioration of the quality of the wound web. There was a problem. In recent years, the speed of winding has been gradually increased. However, in the case of winding at high speed, the winding speed is limited due to the danger of a single shaft, which has been a factor in hindering speeding up.

SUMMARY OF THE INVENTION The present invention addresses the above-described situation, and in particular, finds that a multi-axis turret winding machine for winding a slit device is divided and arranged on the upper and lower turret base shafts and a plurality of turret winding shafts are installed. It is an object of the present invention to reduce the distance between the cores of a take-up winding shaft, prevent deflection and vibration of the take-up shaft (core), and improve winding efficiency and quality of a winding web. .

[0005]

That is, according to the present invention, which meets the above-mentioned object, a plurality of turret winding machines arranged in a row on a turret base shaft in which the winding shaft in a slit device is vertically divided. The turret winder is composed of a take-up shaft and can be moved along guide rails provided in the width direction corresponding to the cutting width, and the web is cut near the web take-up position of the take-up shaft. And a web wrapping device, and a web cutting device and a web wrapping device.
Turret winding machine
It is characterized by a length of the width . In order to divide the plurality of turret winders vertically and arrange them in a row, it is preferable to arrange the upper and lower turret winders in a zigzag manner by shifting the phases vertically . In addition , it is advantageous that each of the turret winders arranged above and below is provided with a drive motor so as to be independently driven.

[0006]

According to the present invention, the wide web to be slit is slit into a required number of slits in the width direction, and then the turret base axes which are vertically divided are arranged in a horizontal row, each having a central axis. Winding is continuously performed on the winding shafts of a plurality of turret winders. Then, when the predetermined winding is completed, it is wound around a new winding core according to the operation of the turret winding machine, and the winding is continued again. At this time, the distance between the cores of the winding shafts is shorter than in the case of single-shaft multiple winding, so that bending and vibration of the winding cores are prevented and smooth winding is enabled. In addition, when the upper and lower turret winders are arranged out of phase when they are wound up and wound on the winding shaft, the slit narrow webs are alternately sent up and down,
Winding is performed without interfering with each other. In addition, when there is a change in the web cutting width, the turret winding machine is moved by moving the winding width according to the guide rail.

In the above-mentioned winding, if the touch roller and the cutter extend over the entire length of the winding width in each of a plurality of upper and lower turret winding machines, the winding and cutting operations can be performed by one arm turn. Operation, and operation is simplified. In addition, by independently driving each turret winder, winding can be performed with a tension corresponding to the slit web.

Each of the two turret winders is arranged in two upper and lower stages in the illustrated example. In the lower stage, a total of four turret winders are provided in a horizontal arrangement, which are vertically shifted in phase from each other, and are arranged alternately in a zigzag shape. This is to avoid mutual interference between the webs at the time of winding, and it is preferable to arrange the cores so that the core positions do not overlap vertically.

Each of the above turret winders can be moved via slide bearings 36 along guide rails 25 and 26 provided on the turret base shafts 21 and 22 so as to correspond to the cutting width. The turret winding shafts 21 and 2
Intermediate bearings 16 and 17 for suppressing the deflection of 2 are slidably disposed along the rails 18 and 19, respectively.

In the illustrated example, the turret winders arranged in a plurality of rows in upper and lower two stages are symmetrically arranged between adjacent turret winders, but each has the same structure independently driven by a motor. Hereinafter, in describing the structure of the turret winder, only one turret winder will be described and will be described with reference to FIG.

That is, as shown in FIGS. 2 and 3, the turret winder has an upright wall surface of a take-up arm 23 disposed on a turret base shaft 21 on a driving side via a slide bearing 36. A chuck opening / closing air cylinder 27 is fitted to the end of the cylinder rod 28.

Further, the left motor M shown in FIG.
Reference numerals ₁ and M ₂ denote motors for rotating the upper and lower turret shafts 21 and 22, respectively. Transmission mechanisms 34 and 34 ′ are attached to worm wheels 33 and 33 ′ fitted to the ends of the turret shafts 21 and 22, respectively. The turret base shaft is turned in conjunction with the turret. Turret base shaft 21, 2
The right ends 35, 35 'of 2 are slip rings for each motor.

In the above description of the apparatus, a description has been given of a two-tiered arrangement, but the present invention is not limited to two-tiered arrangements, but includes three or more-tiered arrangements.
In addition, the arrangement is not limited to two turret winding machines in each stage, and three or more turret winding machines may be appropriately arranged with their upper and lower phases shifted. 2 more
A multi-axis turret winding machine having three or more axes can also be used in the shaft turret winding machine. These can be appropriately selected according to the total width of the wide web and the number of slits.

According to the present invention, the wide web W is slit into a required number of slits in the width direction, and then the turret base axes arranged vertically are arranged in a horizontal row, each having a central axis. Of the turret winding machine, and continuously winds around the winding core, and when a predetermined winding is completed, the turret is rotated to form a new winding core according to the operation of the turret winding machine. Winding and winding are continued, and even if the number of slits is increased from a web having a width wider than in the past, continuous winding is performed directly and efficiently on the respective winding cores.

If there is a change in the web cutting width,
At any time, the turret winder is moved in accordance with the guide rails to wind up in accordance with the changed width. Moreover,
Even if the tensions of the slit webs are different, the turret winders can be independently driven to wind the webs individually. Thus, it is possible to smoothly take a large number of slits of the wide web formed in the former step compared to the conventional number of slits without causing bending or vibration of the winding shaft, thereby enabling the film forming step. It promotes continuous continuation of slit winding of a wide web, and is very effective.

[0021]

As described above, according to the present invention, in a winding device of a slit device, a plurality of narrow webs obtained by slitting a continuous wide web are wound up to a predetermined length.
The multi-axis turret winder for rewinding to a new winding core is divided vertically and provided in multiple rows so that it can be dissimilar in the web direction.Because it is divided vertically and dissimilar, The distance between the cores of each turret winder can be kept short, and the width of the winding shaft can be minimized, preventing bending and vibration of the winding shaft, especially the turret base shaft, even if the number of slits increases. Thus, even a web having a wider width than the conventional one can be wound at high speed and with high quality.

Further, since the turret winders arranged in each of the upper and lower rows can be moved by sliding along the guide rail, the web cutting is performed in conjunction with the sliding of the winding arms of each turret winder. Even if the width is changed, there is a remarkable effect that the winding can be easily performed according to the cut width. In addition, the turret winders arranged in the vertical direction are alternately arranged in a zigzag shape so as not to hinder the feeding of the upper and lower narrow webs. There is also an advantage that the configuration of the apparatus can be simplified by using a common length for the cutting apparatus and the web winding apparatus. In addition, each of the plurality of upper and lower turret winders arranged in a row has its own motor and is driven independently, so that even if there is a difference in the tension of each narrow web, an appropriate winding can be appropriately performed. There is also an effect that makes taking possible.
