In this connection, blowoff time of the air should be set to very short duration.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention provides a method for manufacturing a web roll in which a web is wound into a coreless roll shape continuously without interrupting the web winding action. This invention relates to a continuous operation type web roll manufacturing apparatus.

(Background of the Invention and Prior Art) Conventionally, as shown in FIG. 11, a wet tissue roll W made by winding wet tissue into a roll shape
A wet tissue roll in a container is commercially available, in which the wet tissue is stored in a container There is.

The wet tissue roll W shown in FIG. 11 is made by winding a single long web without a core, which has been perforated Y for cutting at intervals of a predetermined length (for example, 20 to 30 cm), and then The web roll is stored in a container X in a wet state. Note that this wet tissue roll in a container is taken out from the inner end Wa side of the wet tissue roll W, and is removed by pinching the inner end Wa of the wet tissue roll W with your fingers. If you pull it out hard, it will become the first sewing machine giant shipbuilder Y.
When the portion is pulled out from the outlet Xa, it is cut by the Y portion of the sewing machine to obtain a wet tissue of a certain length.

By the way, the present applicant has already filed a patent application (Japanese Patent Application Laid-Open No. 153066/1983) for a web roll manufacturing apparatus for such a wet tissue roll. As shown in FIG. 12, this known web roll manufacturing apparatus includes a web unwinding device 101 for continuously unwinding a strip-shaped web Q from a raw roll P, and a web unwinding device 101 for continuously unwinding a strip-shaped web Q from a raw roll P; The web Q is perforated at predetermined intervals to form a perforated belt-like web. Perforation processing device 10 for
3, a web winding device 104 for winding the perforated belt-like web R around the web winding core 171, and a web winding device 104 for winding the perforated belt-like web R around the web winding core 171; A web cutting device 105 for cutting off the perforated strip web R and a web roll removing device 106 for removing the web roll T that has been cut off from the perforated strip web R and is supported by the web winding core 171 from the web winding core 171. We are prepared. This web roll manufacturing device is a belt-shaped web Q that is unwound from a raw roll.
The perforations are sequentially perforated at predetermined intervals by the perforation processing device 103, and then the perforated belt-like web R is wound around the web winding core 171 of the web winding device 104. When a web of a predetermined length is wound around the web, the web wound body S is cut at a predetermined perforated portion by the web cutting device 105 to separate the perforated band web R, and then the perforated band web R is cut. The web winding core 171 is separated from R.
removing the web roll T supported by the web roll T from the web winding core 171 by the web roll removing device 106;
Through this series of operations, the web rolls T, T
It is now possible to manufacture...

In addition, in this known continuous operation type web roll manufacturing apparatus,
The web cutting device 105 includes a left and right set of rolls 105A.
, 105B are arranged vertically, and the set roll 105 on the lower side
B is instantaneously rotated at high speed in response to a signal from a counter device that detects when the number of sheets per web roll has been fed out. It is configured to cut five nibs at a perforated portion located between both sets of rolls 105A and IO5B by tearing action.

In the coreless web roll for a wet tissue roll manufactured by this known continuous operation type web roll manufacturing apparatus, the edge in the web width direction is the winding start end (inner end) as shown in FIG. It is manufactured in a relatively neatly aligned state from Wa to the winding end wb. However,
When a wet tissue roll W with neatly aligned edges in the web width direction is stored in a container Since the widthwise edge of the inner side end Wa is aligned with other parts in the width direction, it is difficult to pinch and pull out the inner side end Wa, and the inner side edge of the wet tissue roll Wa to the outlet Xa of the container
The work to set it up was troublesome and took a long time.

Incidentally, if the inner end of the coreless web roll is shifted in the width direction in advance as shown in FIG.
The work when setting the inner end Ta of the web roll to the container outlet Xa becomes easier (there is no need to pull out the inner end Ta of the web roll). Until now, no technology has been found for automatically shifting only the inner end Ta of the web roll in advance in the width direction (as shown in FIG. 1).

(Object of the Invention) In view of the above-mentioned conventional problems, the present invention has been made to continuously roll a web roll in a state in which the inner end of the web roll is automatically shifted in the width direction in advance, as shown in Fig. 1O. The object of the present invention is to propose a continuous operation type web roll manufacturing apparatus that can manufacture web rolls.

The web is configured such that air is blown for a predetermined short period of time in response to a signal so that the web winding start end is shifted from the normal web running lane in the web width direction to obtain winding around the web winding core. It is characterized by

(Function) According to the present invention, a plurality of web winding cores are sequentially circulated between a web end winding position, a web winding position, and a web roll removal position, and the web is continuously run. At the web end winding position, the web end is wound around the web take-up core, and after winding the perforated strip web to a predetermined length at the web winding position, the web is cut by a web cutting device. The web roll supported by the web take-up core can be removed at the roll removal position, allowing continuous operation without stopping the machine drive system (web unwinding device, web take-up device, etc.). Become so.

Further, according to the present invention, when the winding start end of the cut perforated strip web approaches the web end winding position,
In response to a signal from the controller, air is blown out from the air nozzle of the web end wrapping device for a predetermined short time in a direction that shifts the web winding start end in the web width direction. Then, the web winding start end, which is approaching the web end winding position, is wound around the Terranib take-up core in a state that is shifted in the width direction from the normal web travel lane, and when the air nozzle finishes blowing air, the sewing machine The banded web is wound around the web take-up core at a position where it returns to the normal web running lane. Therefore, the web wound body wound around the outer periphery of the web winding core is formed with its inner end portion shifted from the other portion in the width direction. The web roll formed around the outer periphery of the web take-up core is removed from the web take-up core at the web roll removal position, but the inner end of the removed web roll is attached to other parts. In contrast, the web is maintained in a shifted state in the width direction of the web. Further, if the air nozzle of the web end winding device is used to shift the web winding start end in this way, there is no need to install a special web winding start end shifting device.

A web cutting device 5 for cutting S from the perforated strip web R, and for removing the web roll T that has been cut off from the perforated strip web R and supported by the web winding core 71 from the web winding core 71. the web roll unwinding device 6 and the web unwinding device 1
．． A common drive device (this machine drive system) that drives the perforation processing device 3, the circulation drive device (described later) of the web winding core circulation transfer device 7, the web winding device 4, and the web cutting device 5.
8, and a controller 90 for controlling the web cutting timing, the operation timing of the web end winding device 23, the operation timing of the web winding core circulation transfer device 7, the operation timing of the web roll removal device 6, etc. .

The web unwinding device 1, perforation processing device 3, web winding core circulation transfer device 7, web winding device 4, web cutting device 5, and web roll unwinding device 6 each have a large surface area for the web roll P1. It is supported by a vertical plate lO with a

The drive device 8 has a single motor 81 and an endless belt 82 that is circulated by the motor 81. The endless belt 82 is wound around pulleys of the web unwinding device 11, perforation device 3, web winding device 4, and web cutting device 15 on the back side of the vertical plate 10, and is caused to run. and each device (1,
3, 4, and 5) are designed to operate simultaneously.

The speed of the motor 81 of the drive device 8 is variable steplessly, and the speed of manufacturing the web roll can be changed by adjusting the motor rotation speed depending on the type of web roll T to be manufactured (paper quality, paper thickness, etc.). I'm trying to make it possible.

The web unwinding device l has an endless belt 11 that is circulated by the endless belt 82, and by bringing the endless belt 11 into contact with the outer peripheral surface of the web roll P, the web unwinding device 1 unwinds the web from the web roll PfJA. Belt-shaped web Q
It is now possible to unwind.

The perforation processing device 3 is constructed by arranging a fixed roll 31 having a cutter 33 on its outer circumferential surface and a rotating roll 32 having a cutter 34 on its outer circumferential surface adjacent to each other. The strip web Q is passed between cylindrical rolls 31 and 32, and when the rotary roll 32 rotates and the cutter 34 on the rotary roll 32 side contacts the cutter 33 on the fixed roll 31 side, the strip web Q has a full width. Perforations are provided throughout. In addition, this perforation processing device 3 is capable of changing the number of rotations of the rotating roll 32 regardless of the web running speed.
It is designed so that the interval between perforations to be formed on the belt-like web Q can be changed by changing the number of rotations of the belt-like web Q. This perforation process allows the web to be easily cut when cutting the web, which will be described next, and also allows the web to be separated and taken out in certain lengths when it is made into a product.

A web cutting device 5 for cutting the perforated belt-like web R is provided at a position on the downstream side of the perforation processing device 3 in the web running direction and on the upstream side of the web winding device 4. This web cutting device 5 uses a mechanism to be described later to instantaneously apply tension to the running web (perforated) R in its longitudinal direction while continuously operating without interrupting the web winding action. The perforated belt-like web R is cut by tearing it off at the perforated portion.

This web cutting device 5 has a pair of left and right rolls 50A and 50B for transferring the perforated strip web R from the perforation device 3 section to the web winding device 4 section as shown in FIGS. 1 to 3. A set roll 50 having an appropriate interval (for example, about LOCM) from the set roll 50 installation position.
A set of rolls 51 has two left and right rolls 51A and 51B installed at positions separated from each other on the downstream side (lower side) in the web running direction, and one roll of the set of rolls 5I (the right side in FIG. 1) as described later. A high-speed rotation drive device 52 for rotating the roll) 51A at a circumferential speed higher than the web running speed, and a high-speed rotation drive device 52 for rotating the roll) 51A at a peripheral speed higher than the web running speed, and a high-speed rotation drive device 52 for joining and separating the other roll (left roll in FIG. 1) 51B of the set of rolls 51 from the right roll 51A. It is configured to include a contact/separation drive device 53 for causing the movement. The outer circumferential surfaces of the left and right rolls 50A and 50B of the upper set of rolls 50 are in contact with each other, and the perforated belt-like web R running between the cylindrical rolls 50A and 50B can be moved from both sides of the set of rolls 50 without slipping. It's being squeezed. Incidentally, the circumferential speed of each roll 50A, 50B of this upper set of rolls 50 is as follows:
The speed is the same as the web unwinding speed. The right roll 51A of the lower set of rolls 51 is constantly rotated at high speed (for example, web unwinding) by a high-speed rotation drive device 52 consisting of a chain or a belt that is driven at high speed by receiving power from the machine drive system (endless chain 82). Speed 3-5
(double circumferential speed). Further, the left roll 51B in the lower set of rolls 51 is formed by providing a rolling cylinder 56 on the outer periphery of an eccentric ring 55 eccentric to the support shaft 54, as shown in FIG. 3, and a solenoid 57 and a link member. The support shaft 54 is rotated in a reciprocating arc by a predetermined angle range (for example, 5~to'') by the expansion and contraction movement of the solenoid 57 of the approaching/separating drive device 53 consisting of The solenoid 57 of the approaching/separating drive device 53 is normally extended and rotates. The moving cylinder 56 is separated from the right roll 51A, but as described later, when a signal (signal lines t, a) is issued from the controller 90, it contracts momentarily (for example, for 0.5 to 1 second) and then immediately When the solenoid 57 is contracted, the rolling cylinder 56 moves toward the right roll 5.
1A, the rolling cylinder 56 rotates with the right roll 51A (rotates at high speed). A belt 41.41 of a web winding device 4, which will be described later, is passed vertically between the left and right rolls 51A and 518 of the lower set of rolls 51, and this belt 41.41 is installed on the right roll 5IA. It is inserted into the circumferential grooves 59, 59 and is in a free state with respect to both the left and right rolls 51A, 51B. The perforated belt-like web R is guided by the belt 41.41 of the web winding device 4, and is guided between the left and right cylindrical rolls 50A and 50B of the upper set of rolls 50 of the web cutting device 5, and the left and right rolls of the lower set of rolls 51. Although it is made to run continuously from above to below through between 51A and 51B,
When the solenoid 57 of the approaching/separating drive device 53 is contracted, the lower rolls 51A and 51B come into contact, and the perforated strip web R is formed between the upper set of rolls 50 and the lower set of rolls 5I.
The tension generated between them causes them to be torn off at the perforations.

The solenoid 57 of the web cutting device 5 is actuated by a signal (signal line L3) from the controller 90, and this signal (signal line L3) is issued under the following conditions. That is, when the perforation processing device 3 perforates the perforated strip web Q for one product (60 times, for example), and the final perforation that is the planned cutting position is processed. For example, a signal (signal line L1) is emitted from a counter device that measures it, and based on the signal (signal line L1), the final perforation part is positioned at the perforation processing position of the perforation processing device 3. When the web cutting device 5 travels from the web cutting device 5 to the web cutting position E, it is measured by a measuring means (specifically, the number of revolutions of the left roll 50B of the upper set of rolls 50 of the web cutting device 5 is measured by a counter) 91. The signal measured by the measuring means 91 (signal line,
), the controller 90 issues a signal (signal line) for operating the solenoid 57. Therefore, even if the rotational speed of the perforation roll changes, after the final perforation for one product is performed by the perforation device 3, the final perforation will reach the web cutting position WE. Sometimes a web cutting action takes place. That is, even when the speed of the perforation roll is changed, the signal for operating the solenoid 57 (signal line L3, ) is issued and the time it takes for the final perforation section to travel from the perforation position to the web cutting position E are now always the same, so that the perforated strip web is always moved by the final perforation machine. It is now possible to cut at the perforated part.

In this embodiment, the interval between the upper set of rolls 50 and the lower set of rolls 51 of the web cutting device 5 is approximately ioam, and the perforation intervals are usually 20 to 30 cm. Upper and lower roll sets 50 of the web cutting device 5.
51 so that the two perforated parts are not located at the same time. Further, the web is set to be cut when the perforated portion reaches a substantially intermediate position between the upper set of rolls 50 and the lower set of rolls 51.

A total of six web winding cores 71 are used.

Each of the web winding cores 71, 71, . . . is constructed by attaching a roller 73 to the outer periphery of a shaft 72, as shown in FIG. Each web winding core 71°71... is a shaft 72.
The base ends of the large-diameter disk 75 are attached at equal intervals in the circumferential direction near the outer periphery of the large-diameter disk 75. A total of eight grooves 79, 79, . . . are formed in parallel to the axial direction on the outer peripheral surface of the web take-up core 71 (roller 73). By forming the uneven shape on the outer circumferential surface of the web winding core 71 in this way, it becomes difficult to slip between the outer circumferential surface of the web winding core 71 and the web winding start end when the web end is wound, and the web end winding is prevented. You will be able to do it smoothly.

The large-diameter disk 75 has a central axis 76 that is a vertical plate with a bearing 77! It is attached to 0 and can rotate freely. Furthermore, gear teeth 75a are formed on the outer peripheral surface of this large diameter disk 75.

The web winding core circulation transfer device 7 sequentially moves a large diameter disk 75 with a web winding core 71 at an angle of 6 by a circulation drive device 70.
This is for intermittent rotation by 0 degrees. The circulation drive device 70 connects a small diameter disc 78 with gear teeth 78a that engages the gear teeth 75a of the large diameter disc 75 through a clutch device a (with a brake device) 74, which receives power from an endless belt 82 of the drive system of the machine. It is configured to rotate intermittently at a predetermined number of rotations (for example, I/2 rotation), and each time the clutch device 74 is operated, the large diameter disk 75 with a web winding core is rotated clockwise by an angle of 60 degrees. It is designed so that it can be rotated intermittently by °.

When the large-diameter disk 75 is in a stationary state, one of the six web winding cores 71, 71, etc. is at a web end winding position for winding the web end Ra around the web winding core 71. A, the web winding core 71 is located at a position displaced by an angle of 60° in the clockwise direction from the web end winding position A, and is located at the web winding position B, and further to the right of the web winding position B. The web winding core 71, which is displaced by an angle of 120° in the rotational direction, is located at a web roll removal position C for removing the web roll T wound around the web winding core. That is, the web end wrapping position A
The web winding core 71 located at the web winding position B moves to the web winding position B when the clutch device 74 is operated once, and the web winding core 71 located at the web winding position B moves to the web winding position B when the clutch device 74 is operated once.
M It is designed to move to the web roll removal position C when operated twice.

As will be described later, the clutch device 74 receives a signal (for example, a web end winding device described below) issued from the controller 90 immediately after the web end Ra is wound around the web winding core 71 at the web end winding position A. 23 is connected by a signal line L4) issued from the controller 90 immediately after the operation of the controller 90, and the large diameter disk 75 is accurately rotated by an angle of 600 through the small diameter disk 78.

The web winding device 4 is caused to circulate in a range from the position of the right roll 50A of the upper set of rolls 50 in the web cutting device 5, passing through the web end winding position A and the web winding position B, and further reaching a position below the web end winding position A and the web winding position B. A plurality of endless belts 41, 41 are provided. This endless belt 41.41
is caused to circulate by the machine drive system (endless belt 82) at the same speed as the web unwinding speed. Further, this endless belt 41 contacts the outer peripheral surface of the web winding core 7I located at the web end winding position A, and wraps the web end ( At the same time as wrapping the leading edge of the trailing side web) Ra, the web winding position B
The web winding position B is brought into contact with the outer peripheral surface of the web winding body S wound around the web winding core 71 located at the web winding position B.
The web winding body S can be grown around the web winding core 71 at the time.

At the web end winding position A, a web end winding device 23 for winding the web end (the leading end of the perforated strip web R on the trailing side) around the web winding core 71 at the web end winding position A. is provided. This web end winding device 23 is
It is configured as an air blowing type, and the web winding core 71
The first and second nozzles 24 and 25 are located at two positions outside the periphery of the
is installed toward the outer circumferential surface of the web winding core 71 on the downstream side in the rotational direction. Further, as shown in FIGS. 4 and 5, each nozzle 24, 25 is directed in a direction inclined in the web width direction with respect to the web running surface, that is, in this embodiment, the tip of the web winding core 71. It is installed in an inclined state from the side toward the base side, so that the air from each nozzle 24, 25 is blown out in the direction inclined from the tip side of the web winding core 71 toward the base side. It has become. As shown in FIG. 8, when the trailing side web end Ra of the perforated strip web R cut by the web cutting device 5 approaches the web end winding position A, the controller

27) is operated with a time difference after the solenoid 57 of the web cutting device 5 is operated until the trailing end Ra of the cut perforated strip web reaches the web end wrapping position. is set to Furthermore, since the high-pressure air from each nozzle 24, 25 is blown out from an oblique direction in the width direction of the web, the ends of the web (
First, the first nozzle 24 causes the web winding start end (end) Ra to deviate slightly from the normal web running lane in the web width direction (closer to the disk 75) as shown by the chain line Ra' in FIG. Subsequently, the second nozzle 25 further shifts in the web width direction, and the web winding start end n
The web is wound around the web take-up core 71 while being shifted in the web width direction as indicated by the symbol Ra''.

Also, the air blowing time from the nozzles 24 and 25 is such that the web winding start end Ra is around the web winding core 71.
It is sufficient that the winding is performed with the position being shifted about 2 times, and the air is blown out for a very short time (for example, 0.5 to 1 second) and then stopped immediately.

In addition, in this embodiment, when winding the web winding start end Ra around the web winding core 71, apart from the web end winding effect by the air blowing, the web winding start end Ra is wrapped around the web winding core 71.
A web end suction device 18 that sucks air from inside is employed. That is, in the web end suction device 18 using air suction, as shown in FIGS. 2 and 4, the shaft 72 of the web winding core 71 is hollow (reference 84), and the roller 7

The shaft 76 of the large-diameter disc 75 is hollow (reference 86), and the rain hollow parts 84 and 86 are communicated within the large-diameter disc 75, respectively. In addition to providing air passages 87, 87, . . . , a vacuum device 89 is connected to the base end of the shaft hollow portion 86 of the large-diameter disk 75 via an air pipe 88. This vacuum device 89 starts its air suction action in response to a signal from the controller 90 (signal line L7) at the timing when the web winding start end Ra cut by the web cutting device 5 reaches the web end winding position A. When the air suction action is started, the air around the air suction hole 85 of the web winding core 71 is suctioned, and the web winding start end Ra is at the web end winding position A. comes to be attracted around the web winding core 71.

In this way, the web winding start end is located at the web end winding position A.
When approaching the web winding core 71 portion located in The web winding start end is forced to wrap around the web winding core 71 by the recess WIt79 formed on the outer peripheral surface of the web winding core 71. The web winding start end portion can be quickly and reliably wound around the web winding core 71.

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 circulating and transferring device 7 is activated and the web end Ra is wound around the web winding core 71. The winding core 71 is transferred from the web end winding position A to the web winding position B.

At the web winding position B, the endless belt 41 of the web winding device 4 is in contact with the outer surface of the web wound around the web winding core 7I. It acts to grow the web roll S.

At the web winding position B, a belt 41 for winding is in contact with the outer peripheral surface of the web winding body S growing around the web winding core 71 at the position B, and is attached to the outer peripheral surface of the web winding body S. .4
A surface leveling device 9 is installed to prevent marks from being left on the surface. This surface leveling device 9 includes a roller 95 that contacts the entire width of the outer circumferential surface of the web wound body S being grown at the web winding position B;
A suppression device (in this embodiment, a cylinder) 9 for constantly pressing the web against the outer circumferential surface of the web wound body S with a relatively weak pressing force.
6. Note that when the web roll T wound at the web winding position B rotates in the clockwise rotation direction together with the web winding core 71, the roller 95
The web roll T swings under pressure to allow the web roll T to pass therethrough.

At the web roll removal position C, the web roll T formed around the web winding core 7I is removed from the web winding core 7I.
A web roll removal device 6 is provided for removal from 1. As shown in FIG.
By extending the air cylinder 61, the push plate 62 moves forward to the position shown by the chain line 62' in FIG. The web roll T that is being held can be pushed off from the web take-up core 71. The web roll removing device 6 is configured such that the air cylinder 61 expands and contracts only once every time the circulation drive device 70 of the web winding core circulation transfer device 7 operates once.

Next, to explain the usage and operation of the illustrated web roll manufacturing apparatus, first, the web end from the raw roll P is passed through the perforation processing apparatus 3 and the earthwork roll sets 50 and 51 of the web cutting apparatus 5. After passing through the web end winding position, the web is wound around the outer periphery of the web winding core 7I located at the web winding position B as shown in FIG. Then, when the motor 8'1 of the drive device 8 is energized in this state, the endless belt 82 is made to run in circulation, and the web unwinding device l unwinds the strip web Qh from the raw roll P, and the perforation device 3 The belt-like web Q is perforated at predetermined intervals, and the web winding device 4 causes the web winding body S to grow around the web winding core 71 at the web winding position B (FIG. 7). And raw roll P
Immediately after the belt-like web Q of a predetermined length is unwound from the perforation processing device 3, a signal (signal line ri) is emitted immediately after the perforation processing has been performed for one product by the perforation processing device 3. After the signal is emitted, when the measuring device 91 measures a predetermined web running length, the running length measurement signal (signal line) is emitted, and in response to this signal, the controller 90 causes the web to be cut. A signal (signal line Ls) for operating the solenoid 57 of the device 5 is issued, and as shown in FIG. 7, the web cutting device 5 is activated and the rolls 51A and 51B of the lower set of rolls 51 come into contact with each other), Tension is applied to the perforated belt-like web R running between the upper set of rolls 50 and the lower set of rolls 51 in its length direction, so that the perforated belt-like web R is cut at the perforated portion. Both ends of the cut perforated strip web R (
The leading web end Rb and the trailing web end Ra) are guided by the belt 41 and transported to the web end winding position A as shown in FIG.

As shown in FIG. 8, the leading web end Rb is wound around the outer periphery of the growing web S at the web winding position B, and the trailing web end Ra is wound at the web winding position A.
When approaching the web winding core 71 located at
High-pressure air is blown out from each nozzle 24.
9...) causes the web to be instantly wound around the web take-up core 71 (reference numeral Ra' in FIG. 8). At this time, each nozzle 24.
Since the high-pressure air from 25 is blown out from a direction inclined to the web width direction, the web end Ra is blown in the web width direction before the trailing side web end Ra is wound around the web take-up core 71. The web winding start end side of the web wound around the outer periphery of the web winding core 71 is shifted and wound around the web winding core 71 while being shifted.
As shown by the symbol Ra'' in FIG. 5, only the portion shifted in the width direction of the web is wound in a bamboo shoot shape (i.e., shifted in the width direction of the web from the normal winding position).The web Immediately after the web end Ra is wound around the web winding core 71 at the end winding position A, the web winding core circulation transfer device 7 is activated, and the web winding core is at the web winding position B as shown in FIG. Web winding core 7 that has already been wound into a web roll
1 is moved in the clockwise rotation direction, and the web winding core 71, which has already been wrapped at the web end winding position IEA, is moved to the web winding position B, where the web winding body S is moved. You will be able to grow. In this way, the web roll T is sequentially formed around the web winding core 71, and when the web winding core 71 on which the web roll T has been formed reaches the web roll removing position C, the web roll removing device 6 The roll T is now pushed out from the web take-up core 71. At this time, since the uneven shape on the outer circumferential surface of the web winding core 71 is formed toward the axial direction of the web winding core 71, each convex shape pushes the web roll T out of the web winding core 7N. It does not become an obstacle.

As described above, this web roll manufacturing apparatus can continuously manufacture web rolls T without interrupting the winding action, eliminating time loss.

Furthermore, as shown in FIG. 10, the web roll T manufactured by this web roll manufacturing apparatus is manufactured with its inner end Ta shifted in the web width direction. The work of setting the inner end Ta to the container outlet Xa when storing the web roll in the container X can be easily performed (the work of pulling out the inner end of the web roll as in the conventional method is not required). ). Moreover, since the air nozzles 24 and 25 of the web end winding device 23 are used as means for shifting the web winding start end Ra in the width direction, the web winding start end Ra can be shifted as described above. There is no need to use special means for shifting in the width direction, and the web end winding device 23 can be used effectively.

(Effects of the Invention) As described above, the continuous operation type web roll manufacturing apparatus of the present invention can continuously manufacture web rolls without interrupting the web winding action, and improves web roll manufacturing efficiency. It has the effect of being able to.

Further, according to the present invention, high-pressure air from the air nozzles 24.25 of the web end winding device 23 is blown from a direction inclined to the web width direction, and the web winding start end Ra is blown by the high-pressure air to the normal winding start end Ra. The web can be wound around the take-up core 71 in a state shifted in the web width direction from the web running lane, thereby automatically rubbing the inner end Ta in advance in the web width direction. A web roll T having a shape can be manufactured.

Further, according to the present invention, the web roll T has a shape in which the inner end Ta is automatically shifted in advance in the web width direction.
The web winding start end Ra is connected to the air nozzle 24.2 of the web end winding device 23.
5 is used to shift the web width direction from the normal web running lane, so the web winding start end Ra
There is an advantage that no special device is required to shift the web end winding device 23, and the web end winding device 23 can be used for both web end winding and web end shifting. In addition, in this way, the inner end T
In the web roll T in which a is shifted in advance in the web width direction,
When accommodated in the container X, the inner side end f of the web roll
When f1Ta is set in the container outlet Xa, the work of pulling out the inner end Ta is no longer necessary, and the work of accommodating it into the container can be done easily and in a short time.
