TECHNICAL FIELD The present invention relates to a winding shaft loading method and a winding shaft loading device.

[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. 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. The winding shaft U is made of plastic, but weighs about 2 to 3 kg per one.

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.

However, in the web winding machine 101 shown in FIG. 1, although a web winding body for a coreless roll paper can be manufactured, it is necessary to interrupt the continuous web feeding and winding operation for each winding. Therefore, there was a problem that the production efficiency of the web wound body Y was low.

By the way, the present applicant has already proposed a continuous web winding machine capable of manufacturing a web winding for non-core roll paper in a non-stop manner (Japanese Patent Application No. 11-210111). issue).

The web wound body continuous manufacturing machine of this application is
As shown in FIG. 5 to FIG.
And a perforation device 12 for perforating the continuous web T at predetermined intervals;
Slitter device 13 for dividing continuous web T by product width
And a winding shaft supply device 3 for sequentially feeding the winding shafts U one by one.
And a continuous web around the winding shaft U (each divided web T ₁ )
, A guide path 4 for guiding a winding shaft U supplied by a winding shaft supply device 3 to a web winding portion 20, and a web wound by the web winding portion 20. It has a cutting device 6 for separating the wound body X from the continuous web T, and a liquid applying device 5 for wetting the winding start end wound around the winding shaft U in the guide passage 4 with liquid. I have.

The winding device 2 includes a first winding roller 21 and a second winding roller 21.
It has a winding roller 22 and a pressing roller 23. Then, each divided web T ₁ divided by the slitter device 13
Is wound around the first take-up roller 21 and the web take-up section 2
It is led to 0. The web take-up speed in the web take-up unit 20 is considerably high at about 520 m / min in a normal operation.

The guide passage 4 has a pair of guide side plates 41 for respectively supporting portions near both ends of the winding shaft U. The upper surface of each of the guide side plates 41 is an arc surface, and the lower surface of the first winding roller 21 is separated from the outer surface of the first winding roller 21 by an interval corresponding to the diameter of the winding shaft U. Has been installed. Then, the guide passage 4, the starting end side winding shaft U put into the winding shaft insertion portion 42 of the contact to the outer surface of the first winder roller 21 (split web T ₁ is being wound) By doing so, it can be moved to the web winding unit 20 while rotating.

The take-up shaft feeder 3 feeds the take-up shaft U stored in the holder 30 by a conveyor (chain 31 and receiving piece 32) one by one into a take-up shaft input section 4 of the guide passage 4.
2. At the position immediately before the end of the conveyor, the gluing device 15 causes the glue to adhere to the outer surface of the winding shaft U.

[0013] cutting device 6 may swung between an operating position in contact member 61 (each split web T ₁ is equal to the) a standby position and the chain line shown for the solid line shown FIG. 6 (reference numeral 61 ') Like that. At the moment when each of the divided webs T ₁ of the product length is wound around the winding axis U in the web winding section 20, the cutting device 6 changes the contact material 61 to the reference numeral 6.
By contacting the outer surface of the first winder roller 21 as shown by 1 '(pressing each split web T ₁ at the contact member tip), each of said split web T giving tension to each split web T _{1 1} can be torn at each perforation.

In the liquid applicator 5, a wet bed 51 is provided in the guide passage 4 so that the outer surface of the winding shaft U which moves while rotating the guide passage 4 is in contact with the wet bed 51. Then, this liquid with device 5, the winding start end portion of each split web T ₁ which is wound around the take-up shaft U in the guide passage 4 portions a predetermined length (winding shaft U is passed over the water bed 51 The wet bed 51 is wetted only during the period until the wet bed 51).

[0015] In the web wound body continuous manufacturing machine of this application (Figs. 5 to 7), each of the rollers (21, 22) of the feeding device 11, the perforation device 12, the slitter device 13, and the winding device 2 is used. , 23) are continuously driven, and each time a continuous web (each divided web T ₁ ) of a product length is wound around the winding axis U in the web winding section 20, cutting of the continuous web by the cutting device 6 is performed. supply of the winding shaft U from the winding shaft feeder 3 to the winding shaft insertion portion 42, the guide channel 4 portion of each split web T ₁ for winding shaft U of the tip winding and take-start portion of the After the liquid is applied, the winding shaft U that has been wound on the web tip side is moved to the web winding unit 20,
Therefore, a continuous web (each divided web T ₁ ) is wound around the winding shaft U by a predetermined length, and a web winding body is sequentially manufactured in a non-stop manner. As described above, when the non-stop operation is performed, the manufacturing efficiency is dramatically improved as compared with the case of FIG. 1 in which the winding operation is interrupted for each product.

[0016]

By the way, in the web wound body continuous manufacturing machine of the above-mentioned application (FIGS. 5 to 7), the winding shaft U is kept stationary (non-rotating) by the winding shaft supply device 3. After being fed into the take-up shaft input section 42 of the guide passage 4 in the state (state), the continuous web (divided web T ₁ ) running on the outer surface of the first take-up roller 21 is contacted and rotated in the guide passage 4. Can be

However, the winding shaft U is not connected to the first winding roller 21.
At the moment when the winding shaft U comes into contact with the split web T ₁ on the outer surface, the winding shaft U comes into contact with the running split web T ₁ in a stationary state (non-rotating state), so that a large frictional resistance is applied to the split web T ₁ . occurs, high tension between the web winding body X which is wound by the contact portion and the web winding section 20 of the take-up shaft U against split web T ₁ is so generated. In particular, when the running speed of the continuous web (each divided web T ₁ ) is high (speed of about 520 m / min in normal operation) and when the weight of the winding shaft U is heavy (the weight is 2 to 3 kg), At the moment when the take-up shaft U in the stationary state comes into contact with the running continuous web (divided web T ₁ ), the frictional resistance (tension against the continuous web) is further increased with respect to the continuous web. With such a web, the continuous web might be cut off by the generation of the tension. In particular, the perforation and the continuous web T are previously set in the slitter 1
In the divided web T ₁ divided in 3, the strength against the tension per row is very weak, and when the winding shaft U comes into contact with only some of the divided webs T ₁ in all rows for some reason, must rotate the take-up shaft U only split web T ₁ which is the contact, there is a problem that the burden to stress (tension) is split web T ₁ of the part that the contact tends piece thousand intensively Was. Thus, some of the divided webs T ₁
If it is cut off at an unexpected place, it will not be possible to wind it on the next winding shaft U, and the subsequent web will be clogged, and subsequent maintenance work will be difficult.

As described above, in the case where the take-up shaft U in the stationary state is rotated while being brought into contact with the running continuous web, for example, a paper tube as a core of a common cored toilet paper is used. Even with a lightweight take-up shaft, the rotational force is rapidly applied while being sandwiched between the guide passages 4, leaving the possibility of web breakage.

The present invention solves the problem of the web wound body continuous manufacturing machine of the above-mentioned application, that is, the problem of web breakage when the winding shaft is inserted in the web wound body continuous manufacturing machine. It is an object of the present invention to provide a winding shaft loading method and a winding shaft loading device which can be improved so that non-stop operation can be reliably performed.

[0020]

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 winding shaft loading method performed by using a continuous web winding body manufacturing machine.

In the continuous web winding machine used in the winding shaft loading method according to the first aspect of the present invention, the winding shaft is sequentially supplied to the web winding section one by one, and the web roll is fed to the web winding section. After winding the continuous web that has been fed out from the winding shaft around the winding shaft by the product length to form a web wound body, the web wound body is separated from the continuous web without stopping the continuous web feeding operation. At the same time, the cut end of the continuous web is wound around the next winding shaft so that the next winding operation can be performed non-stop.

Further, in this continuous web winding machine, when the winding shaft is supplied to the web winding section, the web winding section is provided at a predetermined position on the upper side of the web winding section. After the take-up shaft is brought into contact with the running continuous web in the length range up to the section and the leading end of the continuous web is wound around the take-up shaft, the wound take-up shaft on the web tip side is taken up by the web. It is configured to move to the winding section.

The winding shaft loading method according to the first aspect of the present invention uses the continuous web winding machine described above, and the winding shaft has a continuous peripheral speed in advance immediately before the winding shaft loading section. The winding shaft is rotated until it is substantially the same as the running speed of the web, and the winding shaft is put into the winding shaft input section while being rotated, and the winding shaft is rotated at a speed substantially equal to the running speed of the continuous web. This is performed while keeping the web in contact with the continuous web.

In this continuous web winding machine, the continuous web travels at a considerably high speed of about 520 m / min in a normal operation. The pre-rotation is performed until the peripheral speed becomes approximately 520 m / min, and the winding shaft is inserted into the winding shaft input section while maintaining the rotation speed.

As described above, when the winding shaft is rotated and put into the winding shaft loading section, when the winding shaft comes into contact with the running continuous web, the winding shaft outer peripheral surface and the continuous web are connected. , There is no relative speed difference, and no frictional resistance is generated by the winding shaft on the continuous web. Therefore, even when the running speed of the continuous web is high or the weight of the winding shaft is heavy at the time of loading the winding shaft, tension is generated between the web winding portion and the contact portion of the continuous web in the continuous web. In the meantime, the trouble that the continuous web is broken does not occur.

In this continuous web winding machine, the web winding body is cut off from the continuous web by a cutting device almost at the same time that the winding shaft is inserted into the winding shaft loading section, and the winding shaft is continuously rotated. While winding the leading end side of the continuous web around the winding shaft by contacting the web, the winding shaft wound on the leading end side of the web is moved to the web winding portion, and the continuous web of a predetermined length is there. And a web wound body can be sequentially manufactured in a non-stop manner.

According to the first aspect, a paper tube serving as a core of a product roll may be used as the winding shaft. In that case, the manufactured web winding body is cut by a product dimension together with a paper tube later. According to a second aspect of the present invention, there is provided the winding shaft loading method according to the first aspect, wherein a winding shaft which can be later removed from the web winding body is used, and the winding shaft is loaded. While moving the winding shaft while rotating it in the length range from the part to the web take-up part, the leading end side of the continuous web is wound around the winding shaft with a predetermined small length of liquid during the movement. I am trying to take it.

The second aspect is suitable for producing a web wound body for a coreless roll paper. In this case, the winding shaft must be later removed from the web wound body. . As this type of winding shaft, for example, there is a windable shaft called an air shaft. Then, after the leading end side of the continuous web is wound around the winding shaft in the expanded state while being wet with a predetermined small length of liquid, the continuous web of the product length is wound to produce a web wound body. Thereafter, the liquid on the web winding start end side is dried, the diameter of the winding shaft is reduced, and the winding shaft is removed from the web winding body. 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 winding shaft used in claim 2 is heavier than the paper tube, but when the winding shaft is inserted, the winding shaft is rotated to substantially the same speed as the running speed of the continuous web. Since it is performed in a state, even if the winding shaft is heavy, almost no frictional resistance occurs when it comes into contact with the continuous web. According to a third aspect of the present invention, in the winding shaft loading method of the second aspect, a plurality of winding cores having the same length as a product width are detachably provided around a common shaft as a winding shaft. This is performed by using the inserted web and winding each divided web obtained by dividing the continuous web by the product width at a position corresponding to each winding core.

In the case of the third aspect, if the common shaft of the winding shaft is removed from the manufactured web winding body, it can be separated into a web winding body with a core having a product width, and the web winding start end portion. After the liquid on the side is dried, the core is removed from the web wound body to obtain a product (coreless roll paper). In the case of the third aspect, it is not necessary to use an expensive air shaft as a winding shaft to manufacture the coreless roll paper. The invention of claim 4 of the present application The invention of claim 4 of the present application is directed to a take-up shaft input device of a web wound body continuous manufacturing machine.

The web winding body continuous manufacturing machine used in the present invention is a feeding device for continuously feeding a continuous web from a web roll, and a winding shaft supply for sequentially feeding winding shafts one by one. A winding device for winding a continuous web around a winding shaft, and a web winding device provided at a predetermined position on a web winding portion of the winding device in a running portion of the continuous web. A guide passage that can be moved toward the web winding unit while rotating the winding shaft in a length range reaching the winding unit;
A cutting device for separating the continuous web from the continuous web by winding the continuous web around the take-up shaft at the web take-up unit, and cutting off the leading end of the separated continuous web side in a non-stop manner; It can be wound around a shaft. In addition, this kind of web roll continuous manufacturing machine is disclosed in Japanese Patent Application No.
It has already been proposed in Japanese Patent Application No. 1-210111.

The winding shaft loading device according to a fourth aspect of the present invention is incorporated in the above-mentioned continuous web winding body manufacturing machine, and the winding shaft is wound in advance immediately before the winding shaft loading section. A pre-rotation device that rotates until the peripheral speed of the take-up shaft becomes substantially the same as the traveling speed of the continuous web; And a feeding device.

As the preliminary rotation device, for example, a device in which the winding shaft is rotated by driving the sandwiching roll with the winding shaft sandwiched between three rolls can be adopted. Then, a winding shaft in a stationary state (non-rotating state) is sequentially supplied to the preliminary rotating device portion one by one by a winding shaft supply device. The preliminary rotating device may be continuously driven. Alternatively, the motor may be stopped until the winding shaft is supplied, and driven after the winding shaft is supplied. The operating speed of the web roll continuous production machine, that is, the running speed of the continuous web can be freely adjusted, but the rotating speed of the winding shaft by the preliminary rotating device is also adjusted to the running speed of the continuous web. Control to tune.

The feeding device may be of any suitable structure as long as it can feed the winding shaft into the winding shaft input section while the winding shaft is preliminarily rotated. For example, using the drive roll of the preliminary rotation device, the take-up shaft is rotated to a desired speed at a fixed position, and then the take-up shaft is rotated by continuously rotating the take-up shaft U only with a specific drive roll. It is possible to use a material that can be fed to the take-up shaft input portion side while performing the operation.

By using the winding shaft loading device according to the fourth aspect, the winding shaft loading method according to the first aspect can be carried out, and the winding shaft is brought into contact with the running continuous web without frictional resistance. Can be. According to a fifth aspect of the present invention, in the fourth aspect, a winding shaft which can be later removed from the web winding body is used as the winding shaft, while the leading end of the continuous web is formed in the guide passage portion. A continuous web winding machine equipped with a liquid application device for adhering a liquid to a predetermined small length range is used.

In the continuous web winding machine according to the fifth aspect, the continuous web winding manufacturing method according to the second aspect can be carried out. That is, a web wound body for a coreless roll paper can be manufactured. According to a sixth aspect of the present invention, in the fifth aspect, a plurality of winding cores having the same length as the product width are detachably fitted around a common axis as the winding axis. On the other hand, a web that incorporates a slitter device that divides a continuous web by product width, and winds each of the divided webs obtained by dividing the continuous web by product width at a position corresponding to each winding core of the winding shaft. Uses a continuous wound roll manufacturing machine.

In the continuous web roll manufacturing apparatus according to the sixth aspect, the web roll continuous manufacturing method according to the third aspect can be implemented. That is, a web wound body for a coreless roll paper divided into product dimensions can be manufactured.

As shown in FIGS. 10 to 12, the lower rotating roller 81 has a plurality of large-diameter rollers 83, 83,. Each large diameter roller 83,
In the example shown, the diameter is 182 mm and the width is 44 mm
The winding shaft U is arranged at the same interval as the winding core length (114 mm). Therefore, a space B (FIG. 12) having a width of about 70 mm is formed between the large-diameter rollers 83.
Note that these dimensions are not particularly limited. In the space B between the large-diameter rollers 83, 83, a lifter pad 77 and a glue-containing pad 15a, which will be described later, are installed as shown in FIG. 12, and a guide base plate 40 as shown in FIGS. Are arranged in a fitted state. still,
The outer surface of each large-diameter roller 83 of the lower rotating roller 81 is positioned so as to be substantially the same as or slightly lower than the upper surface of the tip portion of the guide base plate 40.

As shown in FIGS. 10 to 12, the upper rotating roller 85 has a plurality of large-diameter rollers 87 attached to a shaft 86 at predetermined intervals. This upper rotating roller 8

A space C (FIG. 12) having a width of about 64 mm is formed between the holes 3 and 83. Note that these dimensions are not particularly limited.

The upper rotating roller 85 is provided in FIGS.
As shown in the figure, the arm is supported between a pair of left and right swing arms 91, 91. Each of the swing arms 91, 91 is loosely fitted to the shaft 21a of the first winding roller 21 via a bearing. Also, one swing arm 91
A motor 88 for driving the upper rotating roller 85 is attached to the side surface of the motor. In the following description, for the sake of convenience, the side of the swing arm 91 on which the upper rotation roller 85 is mounted above the first winding roller shaft 21a is referred to as a front end side 91a, and the opposite side of the swing arm 91 is referred to as a rear end side 91b. .

Each of the swing arms 91, 91 has a tip 91a considerably heavier than a rear end 91b, and the tip 91a of each swing arm 91, 91 is attached downward by its own weight. It is being rushed. Each swing arm 91, 9
1 has a front end 91a of the swing arm 91
Are mounted. A holding roller 93 is attached to the cylinder 92 at the end of the rod. Then, as shown in FIG. 11, when the cylinder 92 is in the extended state, the pressing roller 93 presses the upper surface of the swing arm rear end side 91b to cause the upper rotation roller 85 of the swing arm tip side 91a to wait at a predetermined height. When the cylinder 92 is reduced, the pressing roller 93 is moved upward as indicated by reference numeral 93 'in FIG. 11 or reference numeral 93 in FIG. 13, so that the supporting force on the swing arm 91 is released.
When the cylinder 92 is in the extended state, the upper rotating roller 85 is wound between the lower surface of the large-diameter roller 87 and the upper surface of the large-diameter roller 83 of the lower rotating roller 81 as shown in FIG. The position is held so that an interval slightly smaller than the diameter of the shaft U is formed. The position of the upper rotating roller 85 in this state is referred to as a winding bearing insertion position for convenience. or,
A stopper 94 is provided on the rear end side 91b of the swing arm 91 to limit the downward movement range of the upper rotation roller 85 when the cylinder 92 is reduced. That is, as shown in FIG. 13, when the cylinder 92 is contracted, the distal end side 91a of the swing arm 91 tends to move downward due to its own weight.
When the take-up shaft U, which has been located between the two, moves to the take-up shaft input section 42 side, the upper rotating roller 85 has been moved down just before contacting the lifter pad 77 and the guide base plate 40 (reference numeral 85 ').
In this state, the upper surface of the swing arm rear end side 91b abuts against the stopper 94 to prevent the upper rotating roller 85 from further moving downward.

The preliminary rotation device 8 operates as follows in conjunction with the winding operation of the web winding unit 20.
That is, as shown in FIG. 9, when the pusher 71 is in a standby state in a reduced state, the lower rotating roller 81 and the upper rotating roller 85 are stopped. In this state, the cylinder 92 for the swing arm 91 is extended, and the rear end 91b of the swing arm 91 is supported by the pressing roller 93 from above, and the upper rotating roller 85 is moved to the winding bearing insertion position. I'm waiting at. Then, as shown in FIG. 11, the pusher 71 extends, and the take-up shaft U is
1 and the upper rotating roller 85 (the winding shaft U is supported by the three rollers 72, 81, 85), and then both motors 84, 88 operate to operate the lower rotating roller 8

5 is accelerated from the stop state until the peripheral speed of each roller becomes substantially the same as the peripheral speed of the first winding roller 21, whereby the peripheral speed of the winding shaft U is reduced from the stop state to the first winding roller. the peripheral speed of the roller 21 (the traveling speed of the split web T ₁₎ is rotated in the clockwise direction until substantially the same speed. At this time, the push roller 72 of the pusher 71 also rotates. When the winding shaft U is being rotated by the lower rotating roller 81, the upper rotating roller 85, and the pushing roller 72, the distance between the lower rotating roller 81 and the upper rotating roller 85 is slightly larger than the diameter of the winding shaft U. Since it is smaller, the winding shaft U does not pass between the rollers 81 and 85. The upper rotating roller 85 is urged downward due to the weight deviation of the swing arm tip end side 91a and is in contact with the winding shaft U. It works.

Next, the take-up shaft U rotated at the position immediately before the take-up shaft input section 42 is fed by the feeding device 7 to the take-up shaft U.
It is sent to the side 42, and this sending device 7 is configured as follows. The feeding device 7 of this embodiment shares the upper rotation roller 85 of the preliminary rotation device 8 and uses a lifter device 74 for separating the rotating winding shaft U upward from the lower rotation roller 81. are doing.

When the cylinders 78, 78 of the feeding device 7 are reduced in this state (the cylinder 92 for the swing arm 91 is also reduced at the same time), as shown in FIGS. 13 and 14, the lifter pads 77, 77. Pushes up the lower surface of the rotating take-up shaft U to separate the take-up shaft U from the lower rotating roller 81. At this time, the upper rotating roller 85 (and the distal end side 91a of the swing arm 91) is also slightly pushed up by the pushed up winding shaft U. Then, the winding shaft U is moved to the upper rotating roller 8.
5 only rotate (clockwise rotation) and lifter pad 7
Are in contact with the outer surface of the winding shaft U, so that the winding shaft U moves rightward while rotating with the upper rotation roller 85. At this time, the winding shaft U moves between the upper rotating roller 85 and the lifter pad 77 while pushing up the upper rotating roller 85 due to the acting force of rotating the winding shaft U to the right. Then, after the winding shaft U passes over the lifter pad 77 while rotating,
While rotating the take-up shaft U with the upper rotating roller 85, the take-up shaft U is pressed onto the guide base plate 40, and the take-up shaft U is fed to the take-up shaft input section 42 as indicated by reference numerals U 'and U ".

The web winding body Y (FIG. 15) cut off at the web winding section 20 rolls on the discharge table 16 as shown in FIG. After being sealed, it is put on the conveyor 17 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 cores fitted around a common axis V.
After each of the web wound bodies P with cores is removed 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.

In the continuous web winding machine of this embodiment, the feeding speed of the continuous web T is 520 m / m in normal operation.
For example, when the length of one roll of the product is 130 m (single roll toilet paper), four web rolls can be manufactured per minute. In the case of two-ply toilet paper, the length of one roll is, for example, 1/2 (eg, 65 m).
However, in this case, eight wound webs can be manufactured per minute. In this web wound body continuous production machine, about 5 seconds is sufficient for one cycle of manufacturing one web wound body, and the production capacity is about 12 per minute.

In the winding shaft loading device according to the embodiment of the present invention,
Before feeding the winding shaft U into the winding shaft input section 42, the winding shaft U
Is rotated by the preliminary rotating device 8 until the peripheral speed of the winding shaft U is substantially the same as the peripheral speed of the first winding roller 21 (the running speed of the continuous web), and the winding shaft U is kept rotating. And is fed into the take-up shaft input section 42. Therefore,
When the winding shaft U comes into contact with the running continuous web (each divided web T ₁ ), no frictional force is generated between the winding shaft U and the continuous web (each divided web T ₁ ). No tension is generated between the winding shaft contact portion and the web winding portion in (1) (the continuous web is not torn carelessly). Especially in continuous perforations placed and product width continuous web T for cutting the web T at a time divided perforations with split web T _1, tear strength per the one column is very weak, while driving as in the present If the winding shaft U is brought into contact with the continuous web (divided web T ₁ ) in a rotating state, no problem occurs. Also, as the winding shaft U,
You can use heavy ones.

The winding shaft loading device of the present invention may be embodied as follows in addition to the above embodiment. First, the rotation of the lower rotation roller 81 and the upper rotation roller 85 of the preliminary rotation device 8 is started and stopped for each winding shaft in this embodiment, but may be performed with continuous rotation. In that case, the winding shaft U is disposed between the lower rotating roller 81 and the upper rotating roller 85.
Before sending out, the winding shaft U is rotated by an appropriate rotating device to about half the final rotation speed (for example, when the circumferential speed of the winding shaft U is 200 to 30).
0 m / min), and then rotate the lower rotating roller 8
1 and the upper rotating roller 85 may be rotated to the final speed. By performing the two-stage rotation in this way, the shock at the start of rotation can be reduced. Also, in this embodiment,
As the feeding device 7, a lifter device 74 is used to separate the rotating take-up shaft U from the lower rotating roller 81. In other embodiments, the lower rotating roller 81 and the upper rotating roller 85 are rotated. The rotation of only the lower rotation roller 81 may be stopped while the winding shaft U is being rotated. In this case, a motor with a powder brake may be used as the motor 84 on the lower rotating roller 81 side.

The winding shaft loading method and the winding shaft loading device according to the present invention have the following effects. The present winding shaft is turned way effect the claims 1 according to claim 1, the continuous web of unwinding operation from master roll S, the supply operation of the winding shaft U, continuous web of winding of the web take-up unit 20 Using a continuous web winding machine that performs non-stop operations, such as separating the web winding body from the continuous web, winding the end of the continuous web around the winding shaft U, etc. At the position immediately before the shaft loading section 42, the winding shaft U is previously rotated until the circumferential speed of the winding shaft becomes substantially the same as the running speed of the continuous web, and the winding shaft U is loaded while the winding shaft U is in the rotating state. The winding is carried out in such a manner that the winding shaft is brought into contact with the continuous web while the winding shaft rotates at substantially the same speed as the running speed of the continuous web.

As described above, when the winding shaft U is rotated and loaded into the winding shaft loading section 42, when the winding shaft U comes into contact with the running continuous web, the winding shaft U contacts the outer peripheral surface of the winding shaft. There is no relative speed difference between the continuous web and the continuous web, so that no frictional resistance is generated on the continuous web by the winding shaft. Therefore, even when the running speed of the continuous web is high or the weight of the winding shaft is heavy at the time of loading the winding shaft, tension is generated between the web winding portion and the contact portion of the continuous web in the continuous web. There is an effect that the trouble that the continuous web is broken during that time does not occur. According to the second aspect of the present invention, in the method of loading the winding shaft according to the first aspect, a winding shaft U that can be later removed from the web winding body is used. While moving the winding shaft U while rotating it in the length range from the feeding portion 42 to the web winding portion 20, the leading end side of the continuous web cut around the winding shaft during the movement is moved to a predetermined small length. We are trying to wind it up while wetting with liquid.

[0086] The web wound body produced in claim 2 is:
When the water at the winding start end is dried, the winding shaft U can be removed from the web winding body, and the web winding body without the core is cut into product dimensions to obtain a product roll paper. Thus, the invention of claim 2 of the present application has an effect that, in addition to the effect of claim 1 described above, a coreless roll paper having a tubular hole with a web joined at the center can be manufactured. According to the third aspect of the present invention, in the method of loading a winding shaft according to the second aspect, a plurality of winding cores Q having the same length as the product width are used as the winding shaft U.
