DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention provides a web roll formed by winding a web into a coreless roll so that the web roll can be continuously manufactured without interrupting the web winding action. The present invention relates to a continuous operation type web roll manufacturing apparatus.

(Prior Art) Conventionally, as shown in FIG. 10, a wet tissue W wound in a roll shape is stored in a cylindrical container X,
For example, a rolled wet tissue in a container is commercially available, which can be taken out from the take-out port Xa of the cylindrical container X by cutting it into a predetermined length at the time of hand-wiping.

The roll-shaped wet tissue W shown in FIG.
A cylindrical container in which a single long web, which has been perforated Y for cutting at predetermined intervals (for example, 20 to 30 cm), is wound in a coreless state, and the web roll is wet with water. It is stored in X. The container-shaped roll-shaped wet tissue is adapted to be taken out from the inner side end portion Wa side of the roll-shaped wet tissue W, and the inner side end portion Wa of the roll-shaped wet tissue W.
If you pick up with your fingers and pull out strongly, when the first perforated Y part is pulled out from the take-out port Xa, it will be cut at the perforated Y part to obtain a wet tissue of a certain length. Has become.

By the way, the present applicant has already applied for a patent (Japanese Patent Application No. 60-295592) for such a continuous operation web roll manufacturing apparatus for a roll-shaped wet tissue. The continuous operation type web roll manufacturing apparatus of the above-mentioned application, as shown in FIG. 11 to FIG.
A web unwinding device 101 for continuously unwinding the web, and a perforation processing device 103 for perforating the web Q unwound from the original roll P at a predetermined interval.
An air jet type web end winding device 102 for winding the winding start end portion Ra of the perforated web R around the web winding core 171, and a web on which the web winding start end portion is wound. A web winding device 104 for winding a web R of a constant length around the winding core 171, and a web winding core 1
A web cutting device 105 for separating the web winding body S formed around 71 from the web R, and a web roll T which is separated from the web R and supported by the web winding core 171. A web roll removing device 106 is provided for removing the web roll 171. In this continuous operation type web roll manufacturing apparatus, the web Q fed from the original roll is sequentially perforated by the perforation processing device 103 at predetermined intervals, and subsequently, the perforated web R is taken up by the web. The web winding core 171 of the device 104 is wound up, and the web winding core 1
When a web of a predetermined length is wound around 71, the web winding body S is separated from the web R by the web cutting device 105, then separated from the web R and supported by the web winding core 171. The web roll T can be continuously manufactured by a series of operations of removing the existing web roll T from the web winding core 171 by the web roll removing device 106.

However, in the continuously operating web roll manufacturing apparatus of this application, since the web winding core 171 used in the web winding device 104 is formed in a smooth columnar shape on the outer peripheral surface, the web R is preceded. Side edge Ra (Figs. 12 and 13
(Fig.) Approaches the web winding core 171 and the frictional force between the web winding start end and the outer peripheral surface of the web winding core 171 is relatively small, and the web end winding device 102
Means that the web end Ra is simply wound around the outer circumference of the web winding core by the air blown out from the air nozzles 124, 125, 126. Therefore, the web leading side end Ra is in the axial direction of the web winding core 171. Sometimes, the web leading edge Ra is not wound around the outer peripheral surface of the web take-up core 171 but a little too far, and then wound up. In this way, when the web winding start end portion is wound with the web winding core 171 displaced in the axial direction, the wound web roll T shifts in the bamboo width direction in the web width direction as shown in FIG. If the web winding start end approaches the outer peripheral surface of the web winding core 171, and the web is not wound around the outer peripheral surface promptly, the web R is continuously supplied. As a result, a slack portion is formed on the web winding start end side.
As shown in the figure, there arises a problem that the web winding start end is wrinkled (or folded) as indicated by reference sign Ra '. When the outer peripheral portion of the web winding core 171 is formed of a material having a large frictional force such as rubber, the web winding start end is less likely to slip on the outer peripheral surface of the web winding core 171. After forming the web roll T around
When the web roll T is removed from the web winding core 171 by the web roll removing device 106, the web roll T cannot be extracted properly due to a large frictional force between the web winding start end and the outer peripheral surface of the web winding core 171. Or, even if it is pulled out, as shown in FIG. 14, the central portion of the web roll is likely to be displaced like a bamboo shoot.

(Object of the Invention) In view of the problems of the continuous operation type web roll manufacturing apparatus of the above-mentioned applicant's application, the present invention manufactures a coreless roll web roll having a good appearance with a simple structure. A web roll that is capable of being continuously manufactured without interrupting the web winding action, and that can be cut cleanly without using a blade when separating the web roll. The purpose is to propose a manufacturing apparatus.

(Means for Achieving the Purpose) The continuous operation web roll manufacturing apparatus of the present invention includes a web unwinding device for unwinding a web from a raw roll, and a web length for a web wound from the raw roll. Perforation processing device for performing perforation processing for cutting in the web width direction at predetermined intervals in the direction, and a web end winding device for winding a plurality of web winding cores for winding the web at the web end. And a web winding core circulating transfer device for sequentially circulating the web winding position for winding the web and a web roll removing position for removing the wound web roll from the web winding core, and each web winding core. Has a hollow cylindrical outer peripheral surface and forms an air suction hole communicating with the hollow portion on the outer peripheral surface, while the air in the hollow portion of the web winding core in the web end winding device is sucked by the air suction device. Suck A web end winding device capable of winding the winding start end of the web around the outer peripheral surface of the web winding core, and a web that has been perforated at the web end winding device and the web winding position. A web winding device capable of sequentially winding the web around each web winding core, and around the web winding core while the web is continuously traveling on the upstream side in the web traveling direction from the web winding device. A web cutting device capable of separating the formed web winding body from the web, and a web roll separated from the web at the web roll removing position and supported by the web winding core is removed from the web winding core. The web cutting device further includes a pair of pinching rolls for pinching the web from both front and back sides, and each pinching roll. It has a high-speed rotation driving device that rotates at high speed in the web feed direction, and in a state where the web is nipped by each nip roll, by rotating each nip roll at a high speed for a very short time in the web, It is characterized in that a tension is applied to the perforated portion in the web length direction so that the perforated portion can be torn off.

(Operation) According to the continuous operation type web roll manufacturing apparatus of the present invention, a plurality of web winding cores are sequentially circulated between the web end winding position, the web winding position, and the web roll unloading position. The web end is wound around the web winding core at the web end winding position, and the web is wound for a predetermined length at the web winding position, and then the web is continuously run by the web cutting device. After cutting, the web roll supported by the web winding core can be removed at the web roll removal position. Therefore, it is possible to continuously manufacture a coreless web roll without stopping the drive system of the machine such as the web unwinding device and the web winding device (without interrupting the web winding action). .

Further, each web winding core has a hollow cylindrical outer peripheral surface, and an air suction hole reaching the inside of the hollow portion is formed in the outer peripheral surface. By sucking with a suction device, the winding start end of the web can be wound around the outer peripheral surface of the web winding core, so that the web winding start end comes into contact with the outer peripheral surface of the web winding core. At this time, the web winding start end is immediately adsorbed to the outer peripheral surface of the web winding core. When the web winding start end is thus attracted to the outer peripheral surface of the web winding core, the web winding start end is less likely to be displaced in the axial direction with respect to the web winding core, and moreover the slack at the web winding start end is caused. Is difficult to do.

Further, the web cutting device is located on the upstream side of the web winding device in the web traveling direction, and in a state where the web is clamped by the pair of clamping rolls, each clamping roll is driven by the high-speed rotation driving device in the web feeding direction. By rotating the perforated portion of the web at a high speed for a very short time, tension is applied to the perforated portion of the web in the web length direction so that the perforated portion can be torn off. No tension is exerted on the web winding portion side, so that the web winding body wound by the web winding portion is not adversely affected. Further, when the web is cut by tearing off in this manner, a blade for cutting the web is not necessary, and moreover, the web can be cut cleanly (in a straight line).

(Effects of the Invention) The continuous operation web roll manufacturing apparatus of the present invention has the following effects.

(1) Perforations are sequentially placed on the web that is continuously unwound from the original roll, the end of the web is wound around the web winding core at the web end winding position, and the web is wound at the web winding position. The web is wound around the core in a roll shape, the web winding body is separated from the web by a web cutting device, and the web roll formed around the web take-up core at the web roll removing position is made into the web take-up core. Since a series of web roll manufacturing processes such as removing from the web can be continuously performed without interrupting the web winding operation,
There is no loss of time and manufacturing efficiency improves.

(2) Use a hollow web winding core with an air suction hole formed on the outer peripheral surface, and suck the air in the hollow part of the web winding core with an air suction device so that the web winding start end is Since the web end winding device is provided so that it can be wound on the outer peripheral surface of the winding core, when the web winding start end comes into contact with the outer peripheral surface of the web winding core, the air sucked by the air suction device is used. The suction action acts to instantly adsorb the web winding start end portion to the outer peripheral surface of the web winding core, thereby making it difficult for the web winding start end portion to shift in the axial direction with respect to the web winding core. It becomes difficult for the web roll to shift into a bamboo shoot shape, and it becomes difficult for the web winding start end to sag, so that the web winding start end does not easily wrinkle, and a good-looking web roll can be manufactured. .

(3) The web cutting device rotates a pair of pressure rolls at a high speed for a very short time by a high-speed rotation driving device to apply tension to the perforated portion of the web in the length direction of the web to form the perforated portion. Since the blade can be torn off, there is no need for a blade for cutting the web, and there is no need to change the blade, and even if there is no blade, you can cut neatly (in a straight line) along the perforations. You can

(4) The web cutting device is located on the upper side in the web running direction by the web take-up device so that the pair of pinching rolls are instantaneously rotated at high speed in the web feeding direction. ), No tension is generated on the web take-up section side, and even if the web is cut by applying tension to the web, it is wound by the web take-up section during the web cutting operation. It does not adversely affect the wound web.

In the web roll removing device 6, the air cylinder 61 expands and contracts only once each time the circulation drive device 70 of the web winding core circulation transfer device 7 operates once.

Next, the method of use and the operation of the illustrated continuous operation type web roll manufacturing apparatus will be described. First, the web end from the original roll P is passed through the perforation processing device 3 and the web feeding device 9 and further at the web end winding position A. Then, as shown in FIG. 5, it is wound around the outer circumference of the web winding core 71 at the web winding position B. Then, when the motor 81 of the drive device 8 is energized in that state, the endless chain 82 is caused to circulate,
The web unwinding device 1 unwinds the web Q from the original fabric roll P, and the perforation processing device 3 perforates the web Q at a predetermined interval.
Thus, the web winding body S is grown around the web winding core 71 at the web winding position B (FIG. 6).
Then, when the web Q having a predetermined length is fed from the original roll P, a signal is issued from, for example, a counter device, and the electromagnetic clutch 5 of the web cutting device 5 is generated by the signal.
5, the web R running between the upper web feed rolls 13A and 13B and the middle web feed rolls (clamping rolls) 14A and 14B is tensioned in the longitudinal direction thereof as shown in FIG. The web R is cut at the perforated portion. During this cutting action, tension acts only in the web running direction from the pinching rolls 14A and 14B, and the web winding body S wound around the web winding portion is not adversely affected when the web is torn off.

Both ends of the web R (leading side web end Rb, trailing side web end Ra) cut by the above-mentioned tearing are guided to the flat belt 17 or the belt 41 and are transferred to the web end winding position A side as they are. It Then, as shown in FIG. 7, the leading web end Rb is wound around the outer circumference of the growing web winding body S at the web winding position B as it is, and the trailing web end Ra is positioned at the web end winding position A. A certain web winding core 7
When it comes into contact with the outer peripheral surface (air suction hole 78) of No. 1, it is instantly wound around the web winding core 71 by the air suction action from the air suction device 90 (eighth embodiment).
Figure). Immediately after the web end Ra is wound around the web winding core 71 at the web end winding position A, the web winding core circulation transfer device 7 is operated to move to the web winding position B as shown in FIG. The existing web take-up core 71 having been wound with the web roll is moved downward, and the web take-up core 71 having been wound with the web end and located at the web end winding position A is moved to the web take-up position B. Then, the web winding body S is allowed to grow. In this way, when the web roll T is sequentially formed around the web winding core 71 and the web winding core 71 on which the web roll T is formed reaches the web roll removing position C, the web roll removing device 6 causes the web roll removing device 6 to move. The web roll T comes to be pushed out from the web winding core 71.

As described above, this web roll manufacturing apparatus can continuously manufacture the web roll T without interrupting the winding action, and there is no time loss.

Further, the web roll T manufactured in this manner does not shift into a bamboo shoot or wrinkle (or fold) at the web winding start end as shown in, for example, FIG. 14 or FIG. The appearance will be good.

Furthermore, since the web cutting device 5 tears at the perforated portion by applying tension to the perforated portion, a blade for cutting the web is not required, and moreover, the web is cut linearly along the perforated line. can do. In this way, when the cut end is linear, the web end winding start action on the web winding core 71 becomes easy, and the web roll winding end end becomes clean.

Further, the web cutting device 5 is located on the upstream side in the web traveling direction with respect to the web winding part, and when the pinching rolls 14A and 14B are rotated at high speed by the high speed rotation drive device 51, the web cutting part 5 is The tension of the web is not generated, so that the web winding body S wound in the web winding portion is not adversely affected.
