Abstract

PURPOSE:To eliminate the need of the operation of drawing out an inner side end part by operating a web shifting device for a few short seconds when a web-cut expecting part arrived at the device to shift a traveling web in the width direction and cutting and winding up the web. CONSTITUTION:A web Q which is unwound from a raw fabric roll P by means of an unwinding device 1 is machined for peforation in a perforation machining position D after passing through a web shifting device 2 and wound up on a take-up core 71 in a web take-up position B. And, as the diameter of wound-up web becomes a defined value, the web Q is cut by means of a web cutting device 5 in a web cutting position E, the cut end is wound up onto the next take-up core 71 in a web end winding position A and, due to the intermittent rotation of a disk 75, a web is moved to the take-up position B and a web roll removing position C in order and a web roll T is removed. Also, when a web-cut expecting part arrives at the web shifting device 2, the device 2 is operated for a few short seconds to shift the web R in the width direction and, in this condition, the web is cut and wound on to the take-up core 71. Thus, the web rolls can be continuously manufactured while eliminating the need of the drawing operation of an inner end part.

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) As shown in FIG. 14, conventionally, a wet tissue W wound into a roll is stored in a container A roll-shaped wet tissue packaged in a container is commercially available, which can be cut into predetermined lengths and taken out from the outlet Xa.

The rolled wet tissue W shown in FIG.
A single long web, which has been perforated Y for cutting at intervals of a predetermined length (for example, 20 to 30 cm), is wound in a coreless state, and the web roll is further wetted with water to form a container X. It is stored inside. The rolled wet tissue in a container is taken out from the inner end Wa side of the rolled wet tissue W, and the inner end Wa of the rolled wet tissue W is touched with a finger. If you pinch it and pull it out strongly, the first sewing machine 1 will be released.
When the processed Y portion is pulled out from the outlet Xa, the sewing machine 1 cuts the processed Y portion 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 rolled wet tissue. As shown in FIG. 15, this known web roll manufacturing device includes a web unwinding device lot for continuously unwinding the web Q from the raw roll P, and a web unwinding device lot for continuously unwinding the web Q from the raw roll P.
a perforation device 103 for perforating the web R at predetermined intervals; a web winding device 104 for winding the perforated web R around a web winding core 171; a web cutting device 105 for cutting off the web wound body S formed around the web R from the web R;
Web roll removing device 106 for removing the web roll T supported by 71 from the web winding core 171
It is equipped with This web roll manufacturing device has a perforation device @
103, the perforated web R is sequentially perforated at predetermined intervals, and then the perforated web R is wound around the web winding core 171 of the web winding device +04. When a length of web is wound, the web wound body S is cut by a web cutting device 105.
The web roll T is separated from the web R by being cut at a predetermined perforated portion by the web R, and then the web roll T, which has been separated from the web R and supported on the web winding core 17K, is removed by the web roll removing device 106. It is now possible to continuously manufacture web rolls through a series of operations.

In addition, in this known continuous operation type web roll manufacturing apparatus,
The web cutting device 1'05 includes left and right set rolls 105.
A and 105B are arranged one above the other, and the set roll 10 on the lower side
5B 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, thereby causing the web tearing action by both sets of rolls 105A and 105B. The web is cut at a perforated portion located between both sets of rolls 105A and 105B.

As shown in FIG. 14, the coreless web roll manufactured by this known continuous operation type web roll manufacturing apparatus has an edge in the web width direction from the winding start end (inner end) Wa to the winding end end. It is manufactured in a relatively neat state up to part wb. However, after storing the web roll W with neatly aligned edges in the web width direction in the container x, the inner end Wa of the web roll is inserted into the outlet of the container X.
When facing a, the widthwise edge of the inner side end Wa is aligned with the other parts in the width direction, so the inner side end W
It was difficult to pinch and pull out the web roll, and the work to set the inner end Wa of the web roll in the outlet Xa of the container X was troublesome and took a long time.

Note that 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. The object of the present invention is to propose a continuous operation type web roll manufacturing apparatus that can manufacture web rolls.

(Means for Achieving the Object) The continuous operation type web roll manufacturing apparatus of the present invention includes a web unwinding device that can continuously unwind a web from a raw roll, and a web roll manufacturing apparatus that can continuously unwind a web from a raw roll. a perforation device capable of perforating a web for cutting in the web width direction at predetermined intervals in the web length direction;
A web end winding position for winding the web ends, a web winding position for winding the web, and a web for removing the wound web roll from the web winding core. a web winding core circulation transfer device that sequentially circulates between the roll removal position and the web winding position; and a web winding core that continuously runs the perforated web at the web end winding position and the web winding position. A web winding device capable of sequentially winding the web around a core; a web cutting device for cutting a web roll at a perforated portion to separate the web roll from the web; and a web roll cut from the web and supported by the web take-up core at the web roll removal position. A web roll removal device for removing the web from the web winding core, and a web shifting device for appropriately shifting the running web in the web width direction over the vehicle length range on the upper side of the web travel from the front web end winding position. and further configured to operate the web shifting device for an appropriate number of seconds in response to a signal from a controller when the portion of the web to be cut by the web cutting device approaches the installation position of the web shifting device. It is characterized by the presence of

(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 web to a predetermined length at the web winding position, the web is cut by a web cutting device, and then at the web roll unloading position. The web roll supported by the web take-up core can be removed when the web roll is removed, allowing continuous operation without stopping the machine drive system (web unwinding device, web take-up device, etc.). Become.

Further, according to the present invention, when the portion to be cut of the web approaches the web shifting device installation position, the web shifting device is operated for a suitable period of time in response to a signal from the controller. Then, the web at the position of the running web that is about to pass through the web shifting device is partially displaced in the width direction, and the portion (planned cutting position) that is displaced in the width direction is moved as it is to the web cutting device. The web is guided and cut there, and then the cut web leading end is wound around the outer periphery of the web winding core at the web end winding position while being displaced in the width direction.

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.

(Embodiment) The present invention will be described in detail with reference to FIGS. 1 to 13. FIG. 1 shows the overall configuration of a web roll manufacturing apparatus according to an embodiment of the present invention. The device includes a web unwinding device 1 for continuously unwinding the web Q from the raw fabric roll P, and a perforation process at predetermined intervals in the length direction of the web Q unwound from the raw fabric roll P. a perforation device 3 for winding the perforated web R, and a plurality of webs (six in this embodiment) for winding up the perforated web R.
a web winding core circulating and transferring device 7 having web winding cores 71, 71, and for sequentially and intermittently circulating each of the web winding cores 71, 71, etc. to be described later. ,
A web winding device 4 for winding the web R around a web winding core 71, and a web cutting device for cutting off the web wound body S formed around the web winding core 71 from the web R. 5, and a web roll removal device 6 for removing the web roll T separated from the web R and supported by the web take-up core 71 from the web take-up core 71.
and a common drive for driving the web unwinding device 1, 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. The device (drive system of this machine) 8 and the running web Q
The web shifting device 2 is configured to shift the portion to be cut by an appropriate width in the web width direction over an appropriate length range.

The above-mentioned raw roll P1 web unwinding device 11 perforation processing device 3, web winding core circulation transfer device 7, web winding device 4, web cutting device 5, web shifting device 2 and web roll unwinding device 6 are respectively - It is supported by a vertical plate lO having a large area.

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 each pulley of the web unwinding device 1, the perforation device 3, the web winding device 4, and the web cutting device 5 on the back side of the vertical plate 10, and runs on the endless belt 82. When you do this, 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 1 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 raw fabric roll P, the web unwinding device 1 unwinds the raw fabric roll P continuously. Web Q can be unrolled by pressing the button.

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 web Q is passed between both rolls 31 and 32, and when the rotating roll 32 rotates and the blade 34 on the rotating roll 32 side contacts the blade 33 on the fixed roll 3 side,
Perforations are formed on the web Q over the entire width. Moreover, this perforation processing device 3 is capable of changing the number of rotations of the rotating roll 32 regardless of the web running speed, and by changing the number of rotations of the rotating roll 32, the number of rotations of the rotating roll 32 is changed. It is designed so that the interval between perforations to be formed can be changed. 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 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 is operated continuously without interrupting the web winding action, and instantaneously applies tension to the running web (perforated) R in its longitudinal direction by means of the side of the machine, which will be described later. The web R is then cut by tearing it off at the perforated portion.

This web cutting device 5 includes a pair of left and right rolls 50A for transferring the perforated web R from the perforation device 3 section to the web winding device 4 section, as shown in FIGS. 1 to 3; 50B, and two left and right rolls 51A and 51B installed at a position spaced downstream (lower side) in the web running direction by an appropriate interval (for example, about LOCM) from the installation position of the set roll 50. The roll 51, a high-speed rotation drive device 52 for rotating one roll 51A of the roll set 51 (the right roll in FIG. 1) at a higher speed than the web running speed, and the other roll of the roll set 51 as described later. It is configured to include a contact/separation drive device 53 for joining/separating the roll (the left roll in FIG. 1) 51B from the right roll 51A. The outer peripheral surfaces of the left and right rolls 50A and 50B of the upper roll set 50 are in contact with each other, and the web R running between the cylindrical rolls 50A and 50B is pinched from both sides without slipping against the roll set 50. ing. In addition, this upper set roll 50
The circumferential speed of each roll 50A, 50B is equal to 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). The circumferential speed is 3 to 5 times the speed. Further, the left roll 51B in the lower set of rolls 51 is attached to a support shaft 54 as shown in FIG.
It is formed by providing a rolling cylinder 56 on the outer periphery of an eccentric ring 55 that is eccentric with respect to the solenoid 57 and link member 58.
The support shaft 54 is rotated in a reciprocating arc by a predetermined angle range (for example, 5 to io'') by the expansion and contraction movement of the solenoid 57 of the approaching/separating drive device 53, and the rolling cylinder 56 is moved relative to the right roll (drive roll) 51A. The solenoid 57 of the approaching/separating drive device 53 is normally extended and does not roll. Although the cylinder 56 is separated from the right roll 51A, as will be described later, the controller 9
When a signal (signal line L3) is emitted from 0, it is momentarily reduced (for example, for 0.5 to 1 second) and then immediately expanded.

When the solenoid 57 is contracted, the rolling cylinder 56 comes into pressure contact with the right roll 51A, so that the rolling cylinder 56 rotates (rotates at high speed) with the right roll 51A. 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 51A. 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. and web (perforated web)
R is guided by the belt 41.41 of the web winding device 4 and passes between the left and right rolls 50A and 50B of the upper set of rolls 50 of the web cutting device 5 and between the left and right rolls 51A and 51B of the lower set of rolls 51. The rolls 51A are continuously moved from above to below, but when the solenoid 57 of the contact/separation drive device 53 is contracted, the lower rolls 51A,
51B come into contact with each other, and the web R is torn off at the perforated portion by the tension generated between the upper set of rolls 50 and the lower set of rolls 51.

The solenoid 57 of the web cutting device 5 is activated by a signal (signal line Ls) from the controller 90, and this signal (signal line L3) is issued under the following conditions. That is, when the perforation device 3 perforates the web Q for one product (for example, 60 times), and the final perforation that is the planned cutting position is processed, for example, A signal (signal line Lυ) is emitted from a measuring counter device, etc., and based on the signal (signal line Ll), the final perforation part is cut into the perforation position of the perforation processing device 3 while the web cutting device 5 When it travels to the web cutting position E according to In response to a signal (signal line 1) issued from the measuring means 91, a signal (signal line t, a) for operating the solenoid 57 is issued from the controller 90. Therefore, if the rotation of the perforated roll Even if the speed changes, the web cutting action is performed when the final perforation section reaches the web cutting position E after the final perforation for one product is performed by the perforation processing device 3. In other words, even when the speed of the perforation roll is changed, the solenoid 5
7. The time until the operation signal (signal lines t, s) is issued is always the same as the time until the final perforation part travels from the perforation position to the web cutting position E. Thus, the web can always be cut at the final perforation. still,
In this embodiment, the upper set of rolls 50 of the web cutting device 5
and the lower set roll 51 is approximately 10 cm apart,
The intervals between the perforations are usually 20 to 30 cm, and two perforations are not located between the upper and lower rolls 50, 51 of the web cutting device 5 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. And each web winding core 71°71・
- The base ends of the shafts 72 are attached at equal intervals in the circumferential direction at positions near the outer periphery of the large-diameter disk 75. or,
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 is rotatable with its central axis 76 attached to the vertical plate 10 by a bearing 77. 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 supplies power from the endless belt 82 of the drive system of the machine to a predetermined small diameter disk 78 with gear teeth 78a that meshes with the gear teeth 75a of the large diameter disk 75 via a clutch device (equipped with a brake device) 74. It is configured to rotate intermittently by the number of rotations (for example, 1/2 rotation), and each time the clutch device 74 is operated once, the large diameter disk 75 with the web winding core is rotated clockwise by an angle of 60 degrees. It is designed so that it can be rotated intermittently.

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 twice. When the web roll is removed, the web roll is moved to the web roll removal position C.

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 () which is emitted from the controller 90 immediately after the operation of the controller 90, so that the large diameter disc 75 can be accurately rotated by an angle of 60° via the small diameter disc 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. Moreover, this endless belt 41 contacts the outer circumferential surface of the web winding core 71 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 trailing side web) Ra around the web winding core 71 at the web end winding position A is provided. There is. This web end winding device 23 is of an air blowing type in this embodiment, and eleventh and second nozzles 24 and 25 are installed at two positions outside the periphery of the web winding core 71. It is installed toward the outer circumferential surface of the winding core 71 on the lower side in the rotational direction. As shown in FIG. 11, when the trailing side web end Ra of the web R cut by the web cutting device 5 approaches the web end winding position A, each of the eleventh and second nozzles 24°25 The high-pressure air is blown out sequentially with a slight time lag, and the high-pressure air blowing is caused by the action and the web winding core 71 times of the endless belt 41 of the web winding device 4, which winds the web end Ra. It is arranged so that it can be wrapped around the core 71.

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, as shown in FIGS. 2 and 4, the web end suction device 18 using air suction has a hollow shaft 72 (reference numeral 84) of the web winding core 71, and a hollow portion of the shaft 72 in the roller 73.

Along with providing six 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. The vacuum device 89 starts its air suction action in response to a signal from the controller 90 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 web winding core 71
The surrounding air is sucked from the air suction hole 85 of the
At the web end winding position A, the web winding start end Ra is 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 a groove 79 formed on the outer peripheral surface of the web winding core 71. The web winding start end 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 at the web end winding position A, the web winding core circulation transfer device 7 is activated to wind the web around the web end Ra. The 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 71. It acts to grow the web roll S.

At the web winding position B, a winding belt is placed in contact with the outer peripheral surface of the web wound body S growing around the web winding core 7 at the position B, and is attached to the outer peripheral surface of the web wound body S. 41.4
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;

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 71 is removed from the web winding core 71.
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.

In this embodiment, the web shifting device 2 is provided above the perforation position in the web running direction.

Note that there is a relatively small interval (for example, an interval of about 10 to 15 cm) on the downstream side of the web shifting device 2 in the web running direction.
A pair of web feed rolls 30, 30 are provided with a distance between them.

The width indicated by reference numeral H in the figure) is determined by the operating stroke of the operating portion +3a of the solenoid 13, and the moving width (4) is set in a range of about 1 to 3 cm.

The solenoid 13 is actuated by a signal (signal line L5) from the controller 90 that is issued when the portion of the web to be cut by the web cutting device 5 approaches the installation position of the pinch roll unit I2. That is, the transmission timing from the controller 90 to the solenoid 13 is, for example, determined by the perforation processing device 3 to produce a product! The number of perforations to be made for the true amount (
For example, every 60 times), and from the time when the final perforation per product is applied, the number of perforations ( For example, it is set to be transmitted at an earlier point in time (for example, once) (i.e., at the 59th time of perforation).

Also, this solenoid 13 is activated for a very short period of time (for example, about 0.5 seconds) when the controller 90 sends a signal, and during that time the web is moved, for example, from 30 to 100 cm.
It is set to run for a certain length.

Next, to explain the usage and operation of the illustrated web roll manufacturing apparatus, first, the web end from the raw roll P is transferred between the two web pinching rolls L 2A, 12 of the web shifting device 2.
B, through the perforation processing device 3 and between the upper and lower rolls 50 and 51 of the web cutting device 5, and further to the web end winding position A.
Then, as shown in FIG. 8, the web is wound around the outer periphery of the web winding core 71 located at the web winding position B. When the motor 81 of the drive device 8 is energized in this state, the endless belt 8
2 is circulated, the web Qh is unwound from the raw roll P by the web unwinding device 1, the perforation is perforated at predetermined intervals on the web Q by the perforation device 3, and the web Q is unwound by the web unwinding device 1. The web winding body S is wound around the web winding core 71 at the web winding position B.
is caused to grow (Figure 9). Immediately before a predetermined length of web Q is unwound from the raw roll P, that is, immediately before perforations are perforated by the perforation device 3 for one product (for example, when the final perforation is performed 60 times) When perforation processing has been performed only 59 times), the solenoid 13 of the web shifting device 2 is operated by a signal from the controller 90 (signal line L5), and the pinch roll unit 12 moves the web as shown in FIG. The web Q is moved in the width direction (direction of arrow X) by a width H, and at this time, the web Q sandwiched between the two web nipping rolls I2A and 12B is also shifted by a width H' in the direction of arrow X from its normal running position. .

The web Q passing through the second part of the web shifting device is
Width H' only for a short period of time when solenoid 13 is operated.
The portion of the web that has been shifted in the direction of arrow X (FIG. 7) and further shifted in the web width direction continues to run through the perforation position to the web cutting position E.

On the other hand, when the perforation device 3 perforates one product, a signal (signal line Ll) is emitted, and after that signal is emitted, the measuring device 91 performs perforation on a predetermined web. When the running length is measured, a running length measurement signal (signal line 1.1) is issued, and in response to this signal, the controller 90 outputs the solenoid 5 of the web cutting device 5.
7. The operation signal (signal line L3) is issued, and the web cutting device 5 operates as shown in FIG.
(each of the rolls 51A, 51B in contact with each other), tension is applied to the web R running between the upper set of rolls 50 and the lower set of rolls 51 in the length direction, and the web R is in the perforated part. Becomes disconnected. This cutting position is set so that the perforation is performed at a perforated portion located on the upper side in the nib running direction within the range (range of 30 to 100 cm) shifted in the direction of arrow X by the web shifting device 2. do. Both ends of the cut web R (leading side web end Rh, trailing side web end Ra) remain shifted in the web width direction as shown in FIG. is guided to the web end winding position A side. As shown in FIG. 11, the leading web end Rb is wound as it is around the outer periphery of the growing web roll S at the web winding position B, and the trailing web end Ra is at the web end winding position A. When approaching a certain web winding core 7I (at this time, the trailing side web end Ra remains shifted in the web width direction as shown by the chain line Ra'' in FIG. 1O), the web end suction device 18 Further, high-pressure air is blown out from each nozzle 24 and 25 of the web end winding device 23, and the uneven shape (concave groove 79.
79...) causes the web to be instantly wound around the web take-up core 71 (indicated by Ra' in FIG. 11). At this time, the web winding start end side that is wound around the outer periphery of the web winding core 71 has a bamboo shoot shape (that is, a state that is shifted in the web width direction from the normal winding position) only in the area that is shifted in the web width direction. ). Immediately after the web end Ra is wound around the web winding core 71 at the web end winding position A, the web winding core circulation transfer device 7 is activated, and the web winding core is moved to the web winding position B as shown in FIG. The web winding core 71, which has already been wound up into a web roll, is moved in the clockwise direction, and the web winding core 71, which has been at the web end winding position A and which has already been wound, is moved to the web winding position B. It is moved and the web roll S is allowed to grow there. In this way, the web winding core 7! web roll around T
is formed, and when the web winding core 71 on which the web roll T is formed reaches the web roll removal position C, the web roll T is pushed out from the web winding core 71 by the web roll removing device 6. At this time, the uneven shape of the outer peripheral surface of the web winding core 71 is different from that of the web winding core 71.
Since it is formed toward the axial direction, the convex shape does not become an obstacle when pushing out the web roll T from the web winding core 71.

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

Moreover, as shown in FIG. 13, 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). ).

(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, it is possible to manufacture a web roll T having a shape in which the inner end Ta is automatically shifted in advance in the web width direction by the web shifting device 2. In addition, in the web roll T whose inner side end Ta is shifted in advance in the web width direction in this way, when storing it in the container X, when setting the web roll inner side end Ta to the container outlet Xa, , the work of pulling out the inner end Ta becomes unnecessary, and the work of storing the container into the container can be done easily and in a short time.
