2. Description of the Related Art Conventionally, as shown in FIG. 13, a web roll T (for example, a roll-shaped towel paper) formed by winding a strip-shaped web of a predetermined length around a core tube U of a fixed length L is commercially available. ing. As a method of manufacturing this type of web roll T, a long web roll (for example, having a length of 1800 to 20) formed by winding a wide strip-shaped web around a long core tube is used.
From about 00 mm to a predetermined product length L (for example, 200 to 30)
0mm) method of cutting one by one, or product length L in advance
There is a method in which a strip-shaped web having a product width is wound around the core tube U.

In the former method of producing a web roll, a web winding machine is used to produce a long web roll having a product diameter from a large-diameter raw roll, and then the long web roll is made to have a product length L by a roll cutting machine. The product web roll T is manufactured by cutting each piece.

On the other hand, in the latter web roll manufacturing method,
The core tubes U formed in advance in the product length L are sequentially supplied to the winding portion of the web winder one by one, and the strip-shaped web formed in advance in the product width is wound around the core tubes U there. The product web roll T is manufactured.

[0005]

However, when the product web roll T shown in FIG. 13 is manufactured and the product length L is cut from the long web roll, it is necessary to install an expensive roll cutting machine. In addition, there is a problem that a cutting process is required.

Further, in the case of directly manufacturing the product web roll T by winding the strip-shaped web having the product width around the core tube U formed in advance to the product length, the core is sequentially wound on the winding portion of the web winding machine. A tube is supplied one by one, and a strip-shaped web is wound around the core tube there. With a conventional web winding machine,
It is difficult to always supply the core tube to the accurate position of the winding portion (the core tube U may be displaced by about 1 to 2 mm in the length direction of the core tube).
And the end surface of the web winding portion V may be displaced in the roll axis direction. Further, in the winding portion of the winding machine, there is no means for accurately rotating the core tube U supplied thereto in a fixed position, and the core tube U may move in the axial direction during the web winding. At that time, the end surface of the web winding portion V to be wound up becomes bamboo shoot-like or uneven. In this way, the core tube U in the web roll T is
If the end surface of the web winding portion is misaligned with the web winding portion V, or if the end surface of the web winding portion V is misaligned, the appearance becomes poor and the commercial value decreases.

The above-mentioned winding machine for producing a long web roll or a winding machine for producing a product web roll is used for cutting a band-shaped web, gluing an end portion, winding a web end around a core tube, and the like. Due to the technical problem of (1), the intermittent operation type in which the winding action is interrupted once for each winding operation is still the mainstream.

In view of the problems pointed out in the above-mentioned prior art, the present invention provides a product web roll by winding a strip-shaped web around a core tube at a web winding position. The web roll can be manufactured in continuous operation without interrupting the winding operation, and the web winding portion wound around the core tube can be always formed at an appropriate position with respect to the core tube. The purpose is to be able to neatly (planarly) align the end faces of.

The outer peripheral surfaces of A and 50B are in contact with each other, and the perforated belt-shaped web R running between the two rolls 50A and 50B is sandwiched against the pair of rolls 50 without slipping. Incidentally, each roll 50A of the upper group roll 50,
The peripheral speed of 50B is equal to the web unwinding speed. The right roll 51A in the lower group roll 51 is
A high-speed rotation driving device 52 including a chain or a belt that is driven at high speed by receiving power from the drive system (endless chain 82) of the machine constantly rotates at a high speed (for example, a peripheral speed of 3 to 5 times the web unwinding speed). It is designed to be used. Further, the left side roll 51B in the lower group roll 51
As shown in FIG. 3, a rolling cylinder 56 is provided on the outer periphery of an eccentric ring 55 that is eccentric with respect to the support shaft 54, and is formed of a solenoid 57 and a link member 58.
By the expansion and contraction of the solenoid 57 of No. 3, the support shaft 54 is reciprocally arc-rotated in a predetermined angle range (for example, 5 to 10 °) to separate the rolling cylinder 56 from the right roll (driving roll) 51A (see the solid line in FIG. 3). (Position) or joining (position shown by chain line 56 'in the figure). Contact and separation drive device 5
The solenoid 57 of No. 3 is normally extended and has a rolling cylinder 56.
After a While allowed apart from the right roll 51A, which is reduced momentarily when the signal from the controller 90 (signal line L ₃₎ is issued as described below (e.g., 0.5 seconds),
It can be extended immediately. When the solenoid 57 is contracted, the rolling cylinder 56 comes into pressure contact with the right roll 51A. Between the left and right rolls 51A and 51B of the lower group roll 51, belts 41 and 41 of the web winding device 4 described later are passed vertically, but these belts 41 and 41 are provided on the right roll 51A. It is inserted in 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-shaped web R is guided by the belts 41, 41 of the web winding device 4 between the left and right rolls 50A, 50B of the upper set roll 50 of the web cutting device 5 and the left and right rolls of the lower set roll 51. The rollers 51A and 51B are continuously run from the upper side to the lower side through 51A and 51B, but when the solenoid 57 of the contact / separation drive device 53 is contracted, both lower rolls 51A and 51B come into contact with each other, and the perforated belt-shaped web R is torn off at the perforated portion by the tension generated between the upper group roll 50 and the lower group roll 51. The solenoid 57 of the web cutting device 5 is operated by a signal (signal line L ₃ ) from the controller 90, and this signal (signal line L ₃ ) is emitted under the following conditions. That is, the perforation processing device 3 performs perforation processing (for example, 60 times) on the strip-shaped web Q per product, and when the final perforation at the scheduled cutting position is processed, for example, A signal (signal line L ₁ ) is emitted from a counter device or the like for measuring the perforation, and the final perforation processing portion is based on the signal (signal line L ₁ ) from the perforation processing position E of the perforation processing device 3. When traveling to the web cutting position F by the web cutting device 5, it is measured by a measuring means (specifically, by the counter, the upper assembly roll 5 of the web cutting device 5 is used).
(This is done by measuring the number of revolutions of the left roll 50B of 0)
The controller 90 outputs a signal (signal line L ₃ ) for operating the solenoid 57 in response to a signal (signal line L ₂ ) measured by the measuring means 99 and received from the measuring means 99. Therefore, even if the rotation speed of the perforation roll changes, after the final perforation processing for one product is performed by the perforation processing device 3, the final perforation processing portion reaches the web cutting position F. Sometimes a web cutting action is performed. That is, even when the speed of the perforation roll is changed, the signal for operating the solenoid 57 (the signal line L ₁ ) is issued after the signal (signal line L ₁ ) issued when the final perforation processing is performed. ₃ ) The time until it is emitted and the time it takes for the final perforated part to travel from the perforated position E to the web cutting position F are always the same, and the perforated web is always the final It is possible to cut at the perforated portion. In this embodiment, the distance between the upper group roll 50 and the lower group roll 51 of the web cutting device 5 is about 10 cm, and the perforation interval is usually 2 cm.
The intervals are 0 to 30 cm, and two perforated portions are not positioned at the same time between the upper and lower rolls 50, 51 of the web cutting device 5. The web cutting is set to be performed when the perforated portion reaches a substantially intermediate position between the upper group roll 50 and the lower group roll 51.

When the web end Ra is wound around the (core tube U), immediately after that, the support rod circulation transfer device 7 is operated to move the support rod 71 around which the web end Ra is wound to the web end winding position B. From the web to the web winding position C.

At the web winding position C, the supporting rod 71
Since the endless belt 41 of the web winding device 4 is in contact with the outer surface of the web wound around the (core tube U),
It acts to grow the web winding S around the support rod 71.

At the web roll removal position D, the support rod 7
A web roll removing device 6 for removing the web roll T formed around the core tube 1 (core tube U) from the support rod 71 is provided. This web roll removing device 6
2 and 4, a push plate 62 is attached to the tip of the rod of the air cylinder 61. By extending the air cylinder 61, the push plate 62 is moved to the position shown by the chain line 62 'in FIG. The web roll T formed around the support rod 71 at the web roll removal position D can be pushed out of the support rod 71 by moving forward. In the web roll removing device 6, the air cylinder 61 expands and contracts only once each time the circulation drive device 70 of the support rod circulating transfer device 7 operates once.

The pressing plate 62 of the web roll removing device 6 is composed of two pieces, an L-shaped piece 62a and a narrow width piece 62b.
Each of them is pivotally supported by shafts 64 and 65 with respect to a mounting plate 63 provided at the tip of the cylinder rod. Further, each piece 62a, 62b of the push plate 62 is, as shown in FIG.
Similar to the abutment plate 45 of the stopper 43, the L-shaped piece 62a is broken by a chain line 62a 'before the support rod 71 enters the web roll removal position D (the position of the chain line 71' in FIG. 8). And the narrow strip 62b becomes the broken line 6
2b ', and when the support rod 71 enters the web roll removing position D, the push plate pieces 62a, 62b come into contact with the outer surface of the support rod 71 as shown by solid lines, and the support rods are shown by chain lines. When it is moved from the web roll removing position D as indicated by 71 ″, the L-shaped piece and the narrow width piece are pressed and displaced as indicated by chain lines 62a ″ and 62b ″, respectively. 62
When the support rod 71 is in the web roll removal position, the pieces 62a, 62b are in contact with the outer surface of the support rod 71. Therefore, the pieces 62a, 62b are attached to the core tube of the web roll T during the web roll removal operation. The web winding portion V wound around the core tube U can press the U portion.
No longer loses its shape.

Next, the method of use and the operation of the illustrated web roll manufacturing apparatus will be described. First, the web end from the original roll P is placed between the upper and lower rolls 50, 51 of the perforation processing device 3 and the web cutting device 5. After passing through the web end winding position B, the web is wound around the outer periphery of the core tube U fitted into the support rod 71 at the web winding position C as shown in FIG.
When the operation is started for the first time, the support rod 71 at the core tube fitting position A and the support rod 7 at the web end winding position B are used.
1 and the core tube U is inserted into the support rod 71 at the web winding position C at a predetermined depth position, and the web end is wound around the core tube U of the support rod 71 at the web winding position C. Wrap Ra.

At this time, the core tube adsorbing device 18 is also operated to adsorb each core tube U fitted into the support rod 71 onto the outer surface of the roller 73 of the support rod. This way,
Each core tube U is softly locked with respect to the roller 73 of the support rod and becomes difficult to move in the axial direction, and the core tube U and the roller 7
3 and 3 rotate together with the shaft 72 of the support rod.

Then, in this state, the motor 8 of the drive unit 8
1 is energized, the endless belt 82 is circulated and run, the web unwinding device 1 unwinds the strip-shaped web Q from the material roll P, and the perforation processing device 3 perforates the strip-shaped web Q at predetermined intervals. Then, the web winding device 4 causes the web winding body S to grow around the support rod 71 (core tube U) at the web winding position C (FIG. 10). Immediately after the strip-shaped web Q having a predetermined length is fed from the original roll P, that is, the perforation processing device 3
A signal (signal line L ₁ ) is emitted when perforation processing is performed for each product by the, and subsequently the measuring device 99 measures a predetermined web running length after the signal is emitted. At that time, the running length measurement signal (signal line L ₂ ) is issued, and in response to this signal, a signal (signal line L ₃ ) for operating the solenoid 57 of the web cutting device 5 is issued from the controller 90. The web cutting device 5 operates as shown.
(The rolls 51A and 51B of the lower set roll 51 are in contact with each other), tension is applied to the perforated belt-shaped web R running between the upper set roll 50 and the lower set roll 51 in the length direction thereof. The perforated belt-shaped web R is cut at the perforated portion. Both ends (leading side web end Rb, trailing side web end Ra) of the cut perforated web W are guided to the belt 41 and transferred to the web end winding position B side as they are, as shown in FIG. . Immediately before the cut web ends Rb and Ra reach the web end winding position B, the lapping device 28 is operated for a very short time so that the support bar 71 located at the web end winding position B moves. Glue is attached to the outer peripheral surface of the inserted core tube U, and the leading web end Rb passes through the web end winding position B immediately after the lapping operation.

As shown in FIG. 11, when the leading web end Rb comes into contact with the outer peripheral surface of the core tube U to which the glue is attached at the web end winding position B, the leading web end Rb. The front side web edge Rb is wound around the outer circumference of the growing web winding body S at the web winding position C as it is and attached. When the trailing web end Ra reaches the support rod 71 at the web end winding position B, the trailing web end Ra comes into contact with the glue attached to the outer peripheral surface of the core tube U, and further the web end winding device 23 of the web end winding device 23. Each nozzle 24,
The high-pressure air blown out from the web 25 instantly winds the web end around the core tube U (reference numeral Ra 'in FIG. 11). Then, at the web end winding position B, immediately after the web end Ra is wound around the support rod 71 (core tube U), the support rod circulating transfer device 7 is operated, and as shown in FIG. The supporting rod 71, which has been wound up with the web roll, is moved in the right rotation direction, and the supporting rod 71, which has been wound up with the end of the web and which has been at the winding position B, is moved to the winding position C. Then, the web winding body S is allowed to grow.

Further, each time the support rod circulating and transferring device 7 is operated once, the core tube supplying device 12 and the core tube fitting device 9 are set to one.
The core tubes U are sequentially inserted one by one into the empty support rods 71 which are operated one by one and moved to the core tube insertion position A.
At this time, the core tube U fitted into the support rod 71 is positioned by the stopper 43 at a predetermined depth position of the support rod 71, and is kept softly locked by the core tube suction device 18. .

In this way, the web roll T is sequentially formed around the support rod 71 at the web winding position C, and when the support rod 71 on which the web roll T is formed reaches the web roll removing position D, the web roll T is formed. The removing device 6 causes the web roll T to be pushed out from the support rod 71. At that time, the push plate 6 of the web roll removing device 6
Since 2 (62a, 62b) presses the core tube U portion of the web roll T, the web winding portion V (see FIG. 13) of the web roll T is not deformed.

This web roll manufacturing apparatus carries out the above-mentioned operations in succession in succession, and the product web roll T as shown in FIG. It can be manufactured (without interruption). Further, even if the web roll to be the final product is manufactured by a single manufacturing apparatus as described above, the web winding part V wound around the core tube U (see FIG. 13) The end faces of can be neatly (planarly) aligned to manufacture high quality web rolls.
