Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous production of a web roll for non-stop production of a web roll for a coreless (no core) roll paper used as toilet paper, kitchen paper and the like. The present invention relates to a method and a machine for manufacturing the method.

[0002]

2. Description of the Related Art In recent years, roll paper for toilets without a core has become widespread. One example of a method for producing this coreless roll paper is disclosed in, for example, JP-A-6-16288. In this known method of manufacturing toilet roll paper, first, as shown in FIG. 1, a web winding machine 101 with a winding shaft Y as shown in FIG.
To manufacture. That is, in the web take-up machine 101 shown in FIG. 1, a wide continuous web T unwound from a web roll S is cut by a slitter device 113 by a product width, and each divided web T ₁ is taken up by a take-up device 102 (2). One take-up roller 12
It is wound by product length around the take-up shaft U at 1,122 and pressing with a roller 123), but a predetermined small length range winding start end portion of each split web T ₁ when the (e.g. 75 10
A liquid for bonding the web is sprayed from the sprayer 105 onto the web (a length range of 0 cm), and the web winding start end is wetted and wound around the winding shaft U. Each split web T ₁ at the web winding section of the winding device 102 after being wound only product length, stops the winding by unwinding and winding device 102 of continuous web T. Next, to discharge the web wound body X formed on the web winder to Kari受109 parts, followed by a knife 161 of the cutting device 106 after cutting each split web T _1, the web winding section The next winding shaft U is supplied, and the winding operation is restarted while spraying the liquid from the spray device 105 toward the winding shaft U for a predetermined short time. In addition, web winding body X
Is separated from the continuous web (split web) as shown in FIG.
A web winding body Y with a winding shaft as shown in FIG.

As shown in FIG. 2, a winding shaft U used in this method of manufacturing a coreless roll paper has a plurality of winding cores Q, Q.・ Removably fits. In addition, caps W, W for retaining are attached to both ends of the common shaft V, respectively. Moreover, each winding core Q, Q · · has a width the same length of each split web T _1, is wound at a position where each split web T ₁ is corresponding to each winding core Q, Q · · respectively Thus, a plurality of web winding bodies P with cores are formed simultaneously.

Then, the common shaft V is removed from the web winding body Y with the winding shaft to separate the web winding bodies P, P,... With the respective cores, and the central portion of the web winding body P with the respective winding cores is separated. After drying, the core Q of the web wound body P with a core is removed by the core removing device 108 as shown in FIG. 3, whereby the coreless roll paper R shown in FIG. 4 can be manufactured. In the centering device 8 shown in FIG. 3, the pressing piece 182 is moved downward by the air cylinder 181, whereby the pressing core 182 of the web wound body P with a core is indicated by a chain line (reference Q '). ) So that it can be removed downward.

Incidentally, as a winding shaft for producing this kind of coreless roll paper, there is a conventional winding shaft which can be expanded and contracted in a radial direction called an air shaft. A web wound body for a coreless roll paper can be manufactured.

[0006] In this way no core roll paper was prepared R, as shown in FIG. 4, with holes R ₁ is formed at the center thereof, made by hardening a web on the sides of the hole R ₁ the tubular portion R ₂ is formed. This tubular part R
₂ is that when the web is bonded with a liquid, the cellulose molecules of the web to be bonded inside and outside are bonded to each other, and when the moisture is dried, the webs are bonded to each other so that the shape retention is maintained. Functions as an insertion hole. In addition, in the non-core roll paper R, nothing remains after the entire use is completed (the core does not remain at the end like a roll paper using a conventional core made of a paper tube), so that it is troublesome to dispose. It becomes unnecessary.

[0007]

By the way, in a web wound body for a coreless roll paper (a web wound body with a winding shaft Y), a predetermined small length range of a web winding start end portion is set at the time of manufacturing. However, when the web is running at a high speed at a normal winding speed, turbulent air (vortex) is generated near the web running surface, Even if the liquid is sprayed on the web surface, the liquid cannot be uniformly attached to the web surface. In particular, in the web winding machine shown in FIG. 1, the nozzle of the sprayer 105 is considerably separated from the winding shaft U supplied to the web winding unit because the web winding X grows in the web winding unit. It is necessary to install the liquid at a position where it is difficult to uniformly apply the liquid to the web winding start end. If the liquid does not uniformly adhere to the web winding start end (the amount of liquid applied is small), the web winding start end may not be wound well around the winding shaft U. As a result, the web There is a problem that the operation must be interrupted due to a winding error at the winding start end. Further, in the case of the coreless roll paper R (FIG. 4) manufactured in such a manner that the liquid adhesion amount near the web winding start end is extremely small, the web binding force at the hole becomes weak, and Web has hole R ₁
And the appearance deteriorates (product value decreases). Further, when the innermost web is peeled, the innermost web is wound around the holder shaft when the toilet roll is used, so that the toilet roll cannot be turned and the web cannot be pulled out. In addition, such a phenomenon becomes a big complaint in the coreless roll paper, and there is a problem that the whole amount is returned to the manufacturer as a defective product.

Due to such a problem, conventionally, as shown in FIG. 1, the continuous web feeding and winding operations are stopped every time one web wound body is wound up, and when the rewinding is started at a low speed. At present, liquid is sprayed toward the surface of the winding shaft. Therefore, the conventional method for producing a web wound body for a coreless roll paper has a problem that production efficiency is low.

On the other hand, some web wound body manufacturing machines using a core made of a paper tube are capable of sequentially manufacturing a web wound body non-stop without interrupting the winding operation. It has been developed (for example, Japanese Patent Publication No. 5-12263). In this continuous web winding machine, since the core made of paper tube is used, it is not necessary to wet the end of the web winding with liquid for forming the center hole. Can be relatively easily changed.
However, in the case of the roll paper made of a web wound body with a paper tube, the paper tube remains when used, and the disposal thereof is troublesome.

In view of the above-mentioned known problems, the present invention has been made to ensure that a predetermined amount of liquid can be adhered to the web winding start end even in non-stop operation, so that a web winding for a coreless roll paper can be performed. The purpose of the present invention is to make it possible to manufacture a cadaver continuously.

[0011]

The present invention has the following structure as means for solving the above-mentioned problems. The invention of claim 1 of the present application The invention of claim 1 of the present application is directed to a continuous production method of a web wound body for a coreless roll paper. That is, the web wound body continuous manufacturing method of claim 1 uses a winding shaft that can be later removed from the web wound body,
The winding shaft is supplied to the web winding section one by one, and the continuous web fed from the raw roll at the web winding section is wound around the winding shaft by a product length to form a web winding body. After forming the continuous web, the web wound body is separated from the continuous web without stopping the continuous web feeding operation, and the cut end of the continuous web side is wound around the next winding shaft, and the next winding is performed. The picking operation is performed non-stop.

According to the first aspect, when the winding shaft is supplied to the web winding portion, the winding shaft is provided within a length range from a predetermined position on the upper side of the web winding portion to the web winding portion. While rotating the web, the continuous web is wound around the winding shaft with a predetermined small length of liquid around the winding shaft during the movement, and then wound on the winding shaft on the web front side. To the web take-up section.

In the present application, the continuous web is fed at a considerable speed in order to perform the non-stop operation.
In the present application, the continuous web tip side is wound around the winding shaft while being wet with a liquid in a length range from a predetermined position on the upper side of the web winding section to the web winding section. In this case, the peripheral speed of the winding shaft is equal to the speed of feeding the continuous web, but the moving speed of the winding shaft is considerably low. Incidentally, the moving speed when the winding shaft moves while rotating is 1/2 of the running speed of the web.
Becomes In addition, a portion of the length range from the upper side of the web take-up section to the web take-up section is provided with a particularly obstructive point for installing a liquid applying device for adhering a liquid to the web winding start end. There is no need for it, so that the applicator can be installed in contact with or close to the winding shaft moving in the area.

As described above, when the liquid applicator is installed in a state of contact with or close to the winding shaft, even if the web is running at a high speed, the web winding start end wound on the winding shaft can be moved. The liquid can be uniformly attached. Therefore, even if a coreless roll paper is manufactured by adhering a liquid to the web winding start end side, non-stop operation can be performed without interrupting continuous web feeding and winding operations.

The web wound body with the winding shaft manufactured by the continuous web wound body manufacturing method of the first aspect is dried from the web winding start end side, and then wound from the web wound body. Pull out the shaft. In this case, for example, an air shaft that can expand and contract in the radial direction may be used as the winding shaft. When the liquid at the start end of the web winding is dried, a relatively hard tubular portion formed by binding cellulose molecules of the web to each other is formed in the center hole of the web winding body. Then, if the web wound body is a long one, it is sufficient to cut off the winding shaft and then cut the product by the product length. The invention according to claim 2 of the present application is directed to the method for continuously manufacturing a rolled web according to claim 1 after dividing the continuous web into product widths.
Each of the divided webs is wound around a winding shaft.

In the manufacturing method according to the second aspect of the present invention, after the liquid at the start end side of the web winding is dried, the winding shaft is removed from the web winding body, and the product divided by the product dimensions (coreless). Roll paper). According to a third aspect of the present invention, in the method for continuously manufacturing a web wound body of the second aspect, a plurality of winding cores having the same length as a product width are attached and detached around a common axis as a winding axis. A flexible web is used, and each divided web is wound around a position corresponding to each core.

In the web wound body with the winding shaft manufactured by the method of claim 3, each web wound body with the winding core is removed from the common shaft, and in this state, the liquid on the web winding start end side is dried. After this, the core is removed from the web wound body to obtain a product (coreless roll paper). In this case, it is not necessary to use an expensive air shaft as the winding shaft. The invention according to claim 4 of the present invention is directed to the continuous production method of a web wound body according to any one of claims 1 to 3, wherein perforations are formed at small intervals in a length direction of the continuous web, The continuous web is torn at a perforation located between the cutting device and the web winding body formed by the web winding section.

The perforations are formed at intervals of, for example, 100 to 300 mm in toilet paper. However, if the perforations are formed on the continuous web in advance in this way, a cutting tool is not used as a cutting device. For example, a cutting device configured to be able to generate a large frictional force (tension) on the web by bringing the contact material into contact with the web can be used. According to a fifth aspect of the present invention, there is provided the web winding body continuous manufacturing method according to any one of the first to fourth aspects, wherein the first winding roller and the first winding roller are provided on the web winding portion. Using a second take-up roller installed with an interval through which the take-up shaft can pass from the outer surface of the roller, guiding the take-up shaft along the outer surface of the first take-up roller to the web take-up portion, When liquid is applied to the leading end side of the continuous web wound on the winding shaft, and when the web wound body formed at the web winding section is separated from the continuous web,
The web is cut at a position closer to the web winding section than a line connecting the axis of the first winding roller and the second winding roller.

In this case, the take-up shaft is supplied to the web take-up portion along the outer surface of the first take-up roller. We let you take up while wetting with liquid only for small length. Further, since the continuous web is cut at a position close to the web winding body formed by the web winding section, the length from the supply position of the winding shaft to the continuous web cutting action position is set. Can be taken longer. Therefore, it is possible to increase the length of the liquid application portion on the leading end side of the continuous web wound around the winding shaft without increasing the diameter of the first winding roller. By the way, the liquid application length on the continuous web tip side is, for example, 800 to 1000 mm.
However, when the continuous web tip is wound around the winding shaft, the web on the leading side from the position where the supplied winding shaft contacts the continuous web (winding start position) is dragged. And wound around the winding shaft. That is, the range of the web length to be dragged is equal to that of the subsequent continuous web.
Wound in heavy condition. Therefore, while the winding shaft passes through the liquid application portion, the web length wound on the winding shaft, including the hand-drawn length portion on the continuous web tip side, can be wet with the liquid. The installation length range of the liquid application part can be shortened, and the diameter of the first winding roller corresponding to the liquid application device does not need to be so large (for example, the diameter may be about 600 mm).

In the case where the perforations are formed in advance on the continuous web, even if the perforation interval is small (for example, 10
(Approximately 0 mm interval), as described above, since the cutting action position of the continuous web is close to the web winding formed by the web take-up portion, two pieces are simultaneously placed between the cutting action position and the web winding. The perforations described above no longer exist. Therefore, the length from the cut end to the winding shaft supply position is always substantially constant, and the liquid application length on the starting end side of the continuous web wound on the winding shaft is substantially constant.

In the case where the continuous web is perforated and the continuous web is divided by the product width, each perforated divided web is wound around a winding shaft at a web winding section. When the cutting action position is close to the web winding body formed by the web winding section as described in claim 5, even if the perforation interval is small, two or more of the web winding bodies are simultaneously provided between the cutting position and the web winding body. The perforated part of the no longer exists. Accordingly, at the time of the cutting operation, each divided web is cut at the perforation at the same position. When the perforation interval of each divided web is small and the length from the cutting action position to the web winding body is long and two or more perforations are present within the length range, each divided web It is not known whether the web is torn at the front or rear perforation within the length range, and the cut positions of the divided webs are not uniform. The invention of claim 6 of the present application The invention of claim 6 of the present application is directed to a continuous web winding machine for coreless roll paper. That is, the continuous web winding machine according to the sixth aspect of the present invention includes a feeding device for continuously feeding a continuous web from a raw roll and a winding shaft which can be later removed from the web winding body. A take-up shaft supply device for supplying one by one, a liquid application device for adhering a liquid to a predetermined small length range at the end of the continuous web, a take-up device for taking up the continuous web around the take-up shaft, A cutting device that separates the continuous web wound around the take-up web from the continuous web is provided, and the cut end of the continuous web is non-stop wound around the next take-up spindle. It is something that you get.

In the continuous web winding machine according to the present invention, the length range from the predetermined position on the upstream side of the web winding section of the winding device in the running section of the continuous web to the web winding section is preferred. A guide passage for rotating the winding shaft toward the web winding unit while rotating the winding shaft, and the liquid application device rotates the web while rotating the web winding start end at the installation position of the guide passage. The liquid can be attached to the spindle from the contact position or the proximity position.

By using the continuous web winding machine of the sixth aspect, the continuous web winding method of the first aspect can be implemented. According to a seventh aspect of the present invention, in the web winding machine according to the sixth aspect, the first winding roller and the outer surface of the first winding roller are wound on the web winding portion. A second take-up roller is provided with an interval through which the shaft can pass. Further, the guide passage is formed along the outer surface of the first winding roller. Further, the cutting device is configured to cut the continuous web at a position closer to the web winding unit than a line connecting the axis of the first winding roller and the second winding roller.

In the continuous web winding machine according to the seventh aspect, the continuous web winding method according to the fifth aspect can be implemented. According to an eighth aspect of the present invention, in the continuous web winding machine according to the sixth or seventh aspect, a water impregnated bed impregnated with a liquid is used as a liquoring device, and the winding shaft is made of a web. It rolls while contacting on the wet bed while winding the winding start end.

[0025] In the web winding machine according to the eighth aspect of the present invention, since the winding shaft rolls while winding the web winding start end and in contact with the wet bed, the web winding start end is formed. The liquid can be reliably and uniformly applied over a predetermined small length range. The invention according to claim 9 of the present invention is directed to the web winding body continuous manufacturing machine according to claim 6 or 7, wherein the liquid applying device is provided with respect to a winding shaft that moves while rotating the installation portion of the guide passage. A spraying device that sprays liquid from a close position is used.

Also in this case, the liquid is applied from a position close to the winding shaft, so that the liquid is applied securely and uniformly over a predetermined small length range of the web winding start end. Can be. In this case, a spraying device is used as a liquid applying device, and the liquid is applied from a position close to the winding shaft. However, the liquid can be satisfactorily applied. The invention of claim 10 of the present application is the invention according to any one of claims 6 to 9.
In the continuous web winding machine, the perforations are formed at small intervals in the length direction of the continuous web using a perforation device, and the continuous web is cut near the web winding section as a cutting device. Uses a contact material that comes into contact with and detaches freely. Then, by bringing the contact material into contact with the continuous web, the contact material can be torn at a perforation portion between the contact portion and the web winding body.

In this case, the contact material of the cutting device is pressed against, for example, a web running on the outer surface of a take-up roller of a take-up device, so that tension is applied between the contact portion and the web winding body. It can be generated and torn at the perforations. According to the eleventh aspect of the present invention, in the continuous web winding machine of the tenth aspect, an intake port to be taken in by an intake device is provided at a contact portion of a contact member of the cutting device, and the continuous web is provided. At the time of cutting, the web surface is sucked to the suction port so that the web surface can be torn at the perforation portion between the suction portion and the web winding body.

In the case of the eleventh aspect, the contact member is brought into contact with the web running on the outer surface of the take-up roller of the take-up device to cause the web to be adsorbed to the suction port, so that the adsorbing portion and the web winding body can be separated. A tension can be generated during the tearing at the perforations.

The guide passage 4 is provided with a liquid applying device 5 for adhering liquid to a predetermined small length range of the winding start end Ta of each of the divided webs T ₁ , T ₁ . In the first embodiment, a wet bed 51 is used as the liquid applying device 5. The water-containing bed 51 is made of a water-retentive material such as a sponge or a cloth material. As shown in FIG. 7, the water-containing bed 51 has a width (vertical length in FIG. 7) substantially equal to the total length of all the winding cores Q, Q,. (Length in the left-right direction in FIG. 7).
Liquid is supplied to the water-containing bed 51 from a water supply device 52 (having a pump 53 and an adjustment valve 54) in an amount corresponding to the amount of liquid consumed per one time. In addition, product width 11
The liquid amount per 4mm is about 15-20cc,
Therefore, the liquid bed 51 is supplied with a liquid amount that is a multiple of the number of products taken at one time.

The upper surface of the water-containing bed 51 has an arc surface concentric with the axial center of the first take-up roller 21 and the first take-up roller 21.
From the outer surface of the winding shaft U (the winding core Q) is spaced at a distance equal to or very slightly smaller than the diameter of the winding shaft U (winding core Q). Since the water-containing bed 51 has a cushioning property, when the winding shaft U enters the guide passage 4 between the first winding roller 21 and the water-containing bed 51, the water-containing bed 51 is recessed and the winding shaft U Is allowed, and the winding shaft U moves while rotating the guide passage 4 so that the liquid is uniformly attached to all the winding cores Q, Q,... Of the winding shaft U. I am getting it.

When the winding shaft U rotates around the guide passage 4 while winding the web winding start end, the liquid applying device 5 starts the web winding around the winding shaft U. The end of the web comes into contact with the wet bed 51 and acts to wet the web winding start end with the liquid impregnated in the wet bed 51 only while the winding shaft U passes over the wet bed 51. The distance from the starting end of the wet bed 51 (the entrance side of the guide passage 4) to a web cutting position described later is 500.
And the total length (800 to 100 mm) of the distance and the length of the wet bed 51 (300 to 400 mm).
(0 mm), the web winding start end can be wetted with the liquid.

When the web of the product length is wound around the winding axis U in the web winding section 20 of the winding device 2, the cutting device 6 wraps the web wound body X into a continuous web (each divided web T). ₁ , T ₁ ..). As shown in FIG. 7, the cutting device 6 of the first embodiment

And a position Xa where the web winding body X fully wound by the web winding unit 20 is in contact with the first winding roller 21 so as to maintain an interval of about 100 mm. First
The contact position with respect to the winding roller is set. In this case, the operation timing of the cutting device 6 is determined by the position where one perforation formed by the perforation device 12 (FIG. 5) makes contact with the outer surface of the first winding roller 21 at the contact material tip 61 a ′. , The web wound body X fully wound by the web winding unit 20
This is performed when the first winding roller 21 is positioned between the first winding roller 21 and the contact position Xa. In addition, the perforation interval is 1
If it is about 00 mm, the fully wound web winding body X contacts the first take-up roller 21 from the position where the leading end of the contact material contacts the first take-up roller 21 in FIG. Since one perforation is interposed between the position Xa and the perforation position Xa, the perforation can be surely torn. However, when the perforation interval is set to be larger than the interval between the reference numeral 61a 'and Xa (for example, 200 (At intervals of up to 300 mm), the arithmetic unit calculates the distance from the perforation position (FIG. 5) of the perforation device 12 to the cutting range (between 61a 'and Xa) and the running speed of the continuous web. First, the cutting device 6 (the shaft 62) is operated when one perforation is located in the cuttable range.

The web winding unit 20 of the winding device 2 has a web winding body Y with a winding shaft formed by the web winding unit 20.
Is provided with a discharge table 16 for discharging the paper. A tail seal device 18 is provided at the outlet side of the discharge table 16.

Next, a description will be given of an operation method of the web wound body continuous manufacturing machine of the first embodiment shown in FIGS. 5 to 13 and a web wound body continuous manufacturing method performed by using the manufacturing machine.

First, when a new material roll S is set, a continuous web T is drawn from the material roll S and its leading end Ta is guided to the vicinity of the web winding portion 20 as shown in FIG. At the time of the first sheet passing, the blades 13a and the edge pressing roller 14 of the slitter device 13 are separated from the first winding roller 21 so that the leading end Ta of the continuous web is removed.
Is led to near the web take-up part 20 while keeping the width wide,
After that, the slitter 13 and the edge pressing roller 14 are set at their proper positions, and the respective devices are slowly moved to move the leading portions of the divided webs T ₁ , T ₁ ,. Then, the leading ends of the divided webs T ₁ , T _1, ... Are cut at perforations. The water-containing bed 51 of the liquid applicator 5 is impregnated with a predetermined amount of liquid. Each of the pushing pieces 32, 32,... Of the winding shaft supply device 3 is loaded with one winding shaft U one by one from the outlet of the holder 30 and guided to the entrance of the guide passage 4. In addition, on the outer surface of each winding shaft U that moves to just before the entrance of the guide passage 4, glue is sequentially attached by a glue-containing roll 15b of the gluing device 15 at a position before that. Further, the first winding shaft U (having glue adhered by the gluing device 15) is placed at the entrance of the guide passage 4 as shown in FIG. In addition, the winding shaft U is located on the lower surface side of each divided web guided along the outer surface of the first winding roller 21.

When the operation is started in this state, the continuous web T is fed from the material roll S by the feeding device 11, and each device (the winding device 2, the perforation device 1) is fed.
2. The slitter 13 and the edge pressing roller 14) are driven. Then, as shown in FIG. 10, the take-up shaft U placed at the entrance of the guide passage 4 rotates with the first take-up roller 21, and the glue adhered to the outer surface of the take-up shaft U at that time. Comes into contact with each of the divided webs, and a part of each of the divided webs is wound around the outer surface of the winding shaft U as shown by reference numeral b in FIG. 10, and thereafter, the winding shaft U moves along the guide passage 4 while rotating. Thus, the leading end side of each divided web is wound around the winding shaft U while being pulled toward the leading end side. or,
At this time, the winding shaft U moves toward the outlet side of the guide passage 4 while rotating on the water-containing bed 51 as shown by the reference numeral U ′ (FIG. 10). The winding start ends are sequentially wetted with the liquid in the wet bed 51.
The liquid application to the web winding start end is performed until the winding shaft passes over the water-containing bed 51, and the length of the liquid application web during that time is 800 to 1000 mm. Then, the winding shaft having the web end wound thereon escapes from the outlet of the guide passage 4 and is wound by two winding rollers 2 indicated by a reference symbol U ″ (FIG. 10).
It moves to the web take-up part 20 via the position between 1 and 22.

In the web take-up section 20, the divided webs are wound around the respective winding cores Q of the take-up shaft U by three rollers 21, 22, 23 as shown in FIG. Is getting thicker. At this time, as shown in FIG. 9, each side edge of each divided web T ₁ , T _1, ... Is set in the annular groove 21 a by the projections 14 a, 14 a. When folded, the side edges of the adjacent divided webs are completely separated from each other (a slight gap is formed), and are wound on the winding shaft U in the separated state. There is no polymerization of each other.

Next, as shown in FIG. 12, when the web of the product length is wound in the web winding section 20, a count-up signal is issued, and the count-up causes each contact member 61 to become the cutting device 6. , 61..
And the leading end thereof and the first take-up roller 21
Each of the divided webs is momentarily held between the outer surfaces of the divided webs. Then, the tip of the contact member 61 'and the web take-up portion 2
Tension is generated in each divided web between the web winding body wound at 0 and the perforated portion of each divided web therebetween is torn off, and each divided web is cut as shown in FIG. Is done. Also, in FIG. 12, almost at the same time when the contact member 61 operates on the cutting side as indicated by reference numeral 61 ′, the winding shaft supply device 3 starts operating and waits just before the entrance of the guide passage 4. The winding shaft U is supplied to the guide passage entrance side as shown by a chain line. The winding shaft U newly fed to the entrance of the guide passage reaches the entrance of the guide passage 4 almost simultaneously with the cutting of each divided web, and the winding shaft U moves along the outer surface of the first winding roller 21. To contact the divided web running. Then, when the glue attached to the outer surface of the winding shaft U comes into contact with each divided web, each divided web of the glue contact portion is wound on the outer surface of the winding shaft U, and the web tip winding operation is started. And
Subsequently, as shown in FIG. 10, after the liquid is wound and wound on the web winding start end by the wet bed 51, the next web winding operation is started in the same manner as described above.

As shown in FIG. 13, the web winding body Y with the winding shaft from which the divided webs are cut off at the web winding section 20 rolls on the discharge table 16 and is mounted on the tail seal device 18. Then, after being tail sealed there, it is placed on the conveyor 17 (FIGS. 5 and 6) and transported to the next process side. As shown in FIG. 2, the web wound body Y with a winding shaft has a plurality of web wound bodies P with a core wound around a common axis V. After removing the wound body P from the common axis V, the liquid near the center is dried. Then, after the drying, if the core Q is removed as shown in FIG. 3, the coreless roll paper R shown in FIG. 4 can be formed.

[0057] In the web winding body continuous manufacturing machine of this embodiment, the cutting of the continuous web T ₁ is located as close to the web windings X formed by the web winding section 20, i.e., first winding Since it is performed slightly on the web winding unit 20 side from the line LL connecting the axis of the roller 21 and the axis of the second winding roller 22, the continuous web is cut from the supply position of the winding shaft U. The length to the action position can be lengthened. Therefore, the first
The length of the liquid-applied portion of the continuous web tip side Ta wound around the winding shaft U can be increased without increasing the diameter of the winding roller 21 so much. Incidentally, the liquid application length on the continuous web tip side is preferably, for example, about 800 to 1000 mm, but when the continuous web tip side is wound around a winding shaft, the liquid is supplied as shown in FIG. take-up shaft U is continuous web T ₁ in contact with the position (winding start position) from the web Ya the front side is wound asked by the take-up shaft Hauling.
That is, the web length range to be dragged is wound in a double state with the subsequent continuous web, and the winding shaft is
While passing over the web 1, the length of the web wound on the winding shaft, including the dragging length portion on the continuous web tip side, can be wetted with the liquid. Therefore, the installation length range of the liquid application part (the water-containing bed 51) can be shortened.
The diameter of the first winding roller 21 corresponding to the water-containing bed 51 does not need to be so large (a diameter of about 600 mm can be used as the first winding roller 21 as in the illustrated example).

In the case where the perforations are formed in advance on the continuous web T ₁ , even if the perforation interval is small (for example, about 100 mm), the cutting position of the continuous web (contact tip portion 61 a) ′ Is in contact with the first winding roller 21) close to the web winding body X formed by the web winding section 20, so that the web winding from the cutting action position (position of reference numeral 61 a ′). Two or more perforations do not exist at the same time until the position Xa where the body is in contact with the first winding roller 21. Therefore, the length from the cut end to the winding shaft supply position is always substantially constant, and the liquid application length on the starting end side of the continuous web wound on the winding shaft is substantially constant. Further, each continuous web T ₁ is cut at the same position in the longitudinal direction, and even if the perforation interval is as small as about 100 mm as described above, the continuous web T ₁ is cut. There is no misalignment.
When the perforation interval of each divided web is small and the length from the cutting action position to the web winding body is long and two or more perforations are present within the length range, each divided web It is not known whether the web is torn at the front or rear perforation within the length range, and the cut positions of the divided webs are not uniform.

A suction port 68 is attached to each of the distal ends of the first and second suction ports 68, and suction is performed from each of the suction ports 68 by a blower 66 via an electromagnetic valve 67. As shown in FIG. 17, the operation timing of the electromagnetic valve 67 on the intake device 65 side is determined by the web winding unit 2.
At 0, the web is turned ON immediately before the web (each divided web) of the product length is wound around the winding shaft U (at this time, each contact member 61 swings toward the first winding roller 21). Turns off immediately after a very short time (after the split web is cut)
It is supposed to work.

Also in the case of the second embodiment, the position of the suction port 68 at the tip of each contact member 61 is different from that of the first winding roller 2.
1 is slightly closer to the web take-up portion 20 side than the line LL connecting the axis of the first take-up roller 22 and the axis of the second take-up roller 22, and the web take-up member X is the first
The distance to the position Xa (FIG. 17) in contact with the winding roller 21 is as small as about 100 mm.

The web wound body continuous production machine of the second embodiment operates as follows. First, before starting operation, FIG.

Each electromagnetic valve 57 of the spray device 55 is turned ON, and the liquid is sprayed from each nozzle 58 toward the guide passage 4. Then, the web winding start end is wound around the winding shaft U while being wetted by a predetermined length (800 to 1000 mm length), and when the winding shaft U reaches the vicinity of the exit of the guide passage 4, Each electromagnetic valve 57 is turned off (spraying is stopped). Subsequently, as shown in FIG. 16, the divided webs are sequentially wound around the winding shaft U in the web winding unit 20. Immediately before the web of the product length is wound around the winding shaft U in the web winding section 20, the electromagnetic valve 67 of the suction device 65 is turned on, and at the same time, as shown in FIG. Swings toward the outer surface side of the first winding roller 21 (in this case, each contact material 61
The divided webs on the outer surface of the first take-up roller 21 come into close or light contact with the divided webs on the outer surface of the first take-up roller. Adsorb. Then, tension is generated between the suction portion by each of the air inlets 68 and the web winding body, and each divided web therebetween is cut off at the perforated portion as shown by reference numeral c in FIG. . Also in the case of the second embodiment, the position of the suction port 68 at the tip end of each contact member 61 is defined by a line LL connecting the axis of the first winding roller 21 and the axis of the second winding roller 22. Slightly closer to the web winding unit 20 side,
The position Xa where the web winding body X is in contact with the first winding roller 21 from the cutting action position (the suction port 68 of the contact material 61).
The interval up to (FIG. 17) is reduced. Therefore, like the first embodiment, only no longer interposed one perforation within the interval, the cutting position of the divided continuous web T ₁ is so aligned neatly. Thereafter, each contact member 61 is immersed in the annular groove 22a on the second winding roller 22 side as shown in FIG. Also, after cutting each divided web with each intake port 68, the suction from the intake port 68 is turned off.
At the same time, the next winding shaft U is supplied to the entrance of the guide passage 4, and the steps of FIGS. 15 to 18 are sequentially repeated.
