Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a web roll manufacturing device for forming web rolls such as roll paper, and more specifically, the present invention relates to a web roll manufacturing device for forming web rolls such as roll paper. The present invention relates to a continuous operation type web roll manufacturing apparatus capable of manufacturing web rolls one after another.

(Prior art) A conventional general web roll manufacturing device has a web winding device that winds a web fed from a raw roll by a web winding device to a predetermined length around a core. However, in this conventional web roll manufacturing apparatus, the operation of the web feeding device and the web winding device is stopped every time one web roll is formed. Because various operations such as cutting off the web roll, discharging the web roll, and supplying the next core were performed during the stoppage, each device (e.g., web feeding device, web winding device, etc.)
The apparatuses have to be turned on and off frequently, which increases the wear and tear of each of these devices and causes problems in that the efficiency of web roll manufacturing is poor.

By the way, recently, in order to improve the problems of the above-mentioned intermittent operation type web roll manufacturing equipment,
Attempts have been made to develop a continuous motion web roll manufacturing device that can continuously manufacture web rolls one after another without interrupting the operation of each device such as a web feeding device and a web winding device. (For example, JP-A-57-77147). In this type of continuous motion web roll manufacturing device, a web winding device winds a predetermined length (product length) of web around the core supply unit and the core to form a web roll with a final diameter. The final web winding section for the winding is arranged in a separate position, and the core supplied to the core supply section is moved to the final web winding section while winding the web around it. We need a mechanism for this. By the way, in the continuous operation type web roll manufacturing apparatus of the above-mentioned known example (Japanese Unexamined Patent Publication No. 57-77147),
As shown in FIG. 13, in the upper winding space _A1 between the first winding roll 211 and the second winding roll 212, the winding cores R are sequentially supplied one by one by the winding core supplying device 204. The leading end of the web Q is wound around the winding core R in a lower winding space A ₂ between the winding rolls 211 and 212 to thicken the web Q. Presser rolls 213 and 214 are provided in the upper winding space _A1 and the lower winding space _A2 , respectively.
These presser rolls 213 and 214 are the web winding body S.
As the winding becomes thicker, it is necessary to move it to the outside of the winding spaces A ₁ and A ₂ . In the web roll manufacturing apparatus shown in FIG. 13, the second take-up roll 212 is swung toward and away from the first take-up roll 211 about a shaft 216 by a displacement actuating mechanism 215. The direction in which the second winding roll 212 is separated from the first winding roll 211 after the leading end of the web is wound around the winding core R in the upper winding space A ₁ The web wound body, which is being moved and is being thickened in the upper winding space _A1 , passes through the closest portion between the two winding rolls 211 and 212 and moves to the lower winding space _A2 ,
Thereafter, the second take-up roll 212 is moved in a direction approaching the first take-up roll 211, and the web wound body S is wound in the lower winding space _A2 until it reaches the final diameter (product diameter). Make you fat. In addition, a new core R is supplied to the upper winding space _A1 just before the web winding body reaches its final diameter in the lower winding space _A2 , and subsequently, when the web winding body reaches its final diameter, a new core R is supplied to the upper winding space A1. The web cutting device 203 operates to cut the web at the perforation portion of the running web, and to wind the leading end of the web on the original roll side around a new core R in the upper winding space _A1 . It is designed to be operated continuously in sequence. In addition, in the continuous operation type web roll manufacturing apparatus of this known example, when the web roll S grown in the lower winding space _A2 reaches its final diameter, the web roll S is provided below the lower winding space _A2 . However, when the web roll S, which has been wound to its final diameter in the lower winding space _A2 , is discharged onto the table 216, the web roll S remains rotated at high speed and remains on the table 216. There is a risk that the web roll S may come into contact with the table surface and violently roll or jump on the table surface. The web wound body S released by the presser member 219 operated by the cylinder 218 presses the web wound body S onto the table 216.
The rotation is stopped immediately. still,
The holding member 219 is operated downward as shown by a chain line 219' to release the web wound body while rotating.
After S' is stopped between the upper surface of the table 216 and the holding member 219, the cylinder 218 is contracted to move the holding member 219 upward. When the presser member 219 moves upward, it is sent from the table 216 to the next process (for example, the web tail gluing process).

However, in the known continuous operation type web roll manufacturing apparatus shown in _FIG . Since the winding device uses a cylinder 218 to move the presser member 219 up and down, the structure is complicated and the presser roll 214 in the lower winding space _A2 is moved back. After that, the time taken for the web wound body S located in the lower winding space _A2 to be discharged onto the table 216 may vary each time the web wound body is discharged (a deviation may occur). Therefore, there was a problem in that adjusting the timing (timing of the extension operation of the cylinder 218) for moving the presser member 219 downward at an appropriate time became troublesome.

(Purpose of the invention) In view of the above-mentioned problems with the conventional web roll manufacturing device, the present invention has been developed to sequentially roll a predetermined length of web around the core without interrupting the operations of the web feeding device and web winding device. In addition to making it possible to continuously manufacture web rolls by winding the web, it is also possible to relatively easily rotate the web roll that is discharged from the outlet of the web winding section while rotating at high speed in such a continuous operation type web roll manufacturing apparatus. The purpose of this invention is to make it possible to stop the vehicle even with a similar configuration, and to do so without having to consider the timing of the braking operation.

(Means for achieving the purpose) The continuous operation type web roll manufacturing apparatus of the present invention has the following features:
A web unwinding device capable of continuously unwinding a web from a web roll; A second winding member such as a belt or a roll that is continuously run in the opposite direction to the running direction of the winding member is juxtaposed to form a web winding portion of a predetermined length range between the two winding members; A web winding device configured such that a web winding body formed by winding a web around a core in a web winding unit is moved from an inlet side of the web winding unit to an exit side of the web winding unit; A web cutting device for sequentially cutting a running web continuously unwound from a raw roll into product lengths, and a winding core for sequentially supplying winding cores one by one to the entrance of the web winding section. a feeding device; and a web end winding device for winding the leading end of the web cut by the web cutting device around a core supplied to the entrance of the web winding section; After the leading end of the web unwound from the web roll is wound around a core at the entrance of the web winding section, the web is wound while winding the web around the core. The web is moved to the exit side of the take-up section, and the trailing end of the web cut off from the original roll by the web cutting device is wound around a web-wound body, and then the web-wound body is web-wound. While being discharged from the outlet of the web take-up part, the core R supplied to the entrance of the web take-up part while continuously running the leading end of the web on the raw roll side cut by the web cutting device. Directly below the outlet of the web winding section, two anti-rotation roll shaft members are arranged so as to be able to be wound around the web roll produced at the web winding section. The rotation of the web rolls can be stopped by supporting the web rolls, which are disposed in parallel with a small interval between them and rotated and discharged from the outlet of the web winding section, between the two rotation stopper roll shaft members. At least one of the rotation stopper roll shaft members is rotated such that the inner surface moves from top to bottom, and the web roll supported between both rotation stopper roll shaft members is rotated in both directions. It is characterized by being equipped with a braking/feeding device that can feed the stop roll shaft material downward.

(Function) The continuous operation type web roll manufacturing device of the present invention has the following features:
A second winding member that is caused to continuously run in a direction opposite to the running direction of the first winding member with respect to a first winding member that is caused to run continuously at a speed equal to the web unwinding speed.
The first winding member and the second winding member are arranged side by side.
A web winding unit having a predetermined length range is formed between the winding members, and the web is further wound around a winding core, and the web winding body moves from the web winding unit entrance side to the web winding unit exit side. Since the web winding device is equipped with a web winding device as shown in FIG. The web being rolled up is moved from the inlet side to the outlet side of the web winding section while becoming thicker, and a new next core can be supplied to the inlet of the web winding section. When a predetermined length of web is wound around the core in the web winding section, the running web is cut by a web cutting device, and the trailing end of the web is wound around the web winding body. Afterwards, the web winding section is discharged from the outlet of the web winding section, while the leading end of the cut web is attached to the newly supplied core by the web end winding device at the entrance of the web winding section. In this way, the web unwinding device and the web winding device can be operated continuously without interruption.

In addition, the web roll discharged from the outlet of the web winding section while rotating at high speed falls between the two rotation stopper roll shaft members of the braking/feeding device and comes into contact with both rotation stopper roll shaft members. The rotation of the web roll is stopped, and then the web roll held between the two rotation stopper roll shaft members is elastically deformed due to the rotation of the rotation stopper roll shaft member, and then both rotations are stopped. It passes between the stop roll shaft members and is sent out below them.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 to 12. The continuous operation type web roll manufacturing apparatus of this embodiment is configured for manufacturing roll paper.

It is configured to include various timing adjustment devices such as an adjustment device 8, a core supply timing adjustment device 6, and a web cutting timing adjustment device 9.

The web feed-out device 1 is of a belt-driven type that contacts the outer peripheral surface of the web roll P and rotates the web roll P in the web pay-out direction.
This web feeding device 1 is designed to be operated continuously during the operation of the web roll manufacturing device, and functions to feed out the web Q continuously. In addition, this web feeding device 1 is of a belt running speed variable type so that the feeding speed of the web can be changed, and the type of web roll to be manufactured (for example, roll paper for toilets, roll paper for kitchens) is adopted. The web can be operated at an appropriate web feeding speed depending on the type of web (such as single-plane or bi-plane).
In this embodiment, two webs Q are stacked and wound into a roll, and two sets of each of the raw roll P and the web feeding device 1 are used.

The perforation processing device 10 is configured by juxtaposing a fixed blade roll 10A with a fixed blade on the outer periphery and a rotary blade roll 10B with a rotating blade on the outer periphery,
When the rotary blade roll 10B is rotated and the rotary blade matches the fixed blade on the fixed blade roll 10A side, perforations are formed at regular intervals in the web Q inserted between both rolls 10A and 10B. It's becoming like that.

The proximity switch 79 calculates the rotation speed of B, and when the proximity switch 79 counts a predetermined number, a signal is emitted from the proximity switch 79, and the signal causes the clutch 27 (described in detail later) to operate. When operated, a cam device 79 is actuated via the roll shaft 24 (described later) and a chain 78. In addition, as described later, the roll shaft 24 is
While the shaft 77 of the cam device 76 rotates exactly one rotation per rotation, the fixed blade 73 protrudes one rotation toward the rotary blade roll side. It's summery. The fixed blade 73 and rotary blades 74, 74 provided on the fixed blade mounting shaft 75 and the rotary blade roll 72, respectively, are as follows:
When the two blades meet (Fig. 10), the cuts are made with uncut portions X, It is designed so that Y, Y, etc. can be entered.
This is to ensure that the planned cutting position of the web Q is moved to the entrance of the web winding device 2. The fixed blade mounting shaft 75 is designed to be immediately returned to the original standby position by a cam device 76 after the fixed blade 73 matches one rotary blade 74, so that the fixed blade 73 can be returned to the original standby position with one operation. is prevented from coming into contact with the two rotating blades 74 (prevention of double cutting). In addition, in this embodiment, the fixed blade mounting shaft 7
The roll shaft 71 supporting the roll shaft 5 is rotatable in an arc by an air cylinder (not shown), etc., and when setting the web wound around the raw roll P, the roll shaft 71 supports the web roll P. By rotating the shaft 71 in an arc, the fixed blade 73 and the fixed blade mounting shaft 75 can be moved to a position (downward) where they do not interfere with paper passing.

The web take-up device 2 includes a first take-up belt 11 and a second take-up belt 12 arranged in parallel and opposite to the first take-up belt 11 .

As shown in FIG. 2, the first winding belt 11 has a narrow width (e.g.
120~130mm) divided belts are separated from each other by a predetermined interval W (for example, about 100mm).
It is wound around two rolls 16A to 16C. In the illustrated example, the roll 16A is the drive roll. This first winding belt 11 is
It is configured to run continuously in the direction of the arrow at the same speed as the web feeding speed by the web feeding device 1.

The second take-up belt 12 has narrow width (for example, about 120 to 130 mm) divided belts 25A to 25 that are divided into a plurality of pieces (10 pieces in total) like the first take-up belt.
Three rolls 26A to 26C are separated from each other by a predetermined distance W' (for example, about 100 mm).
It is made up of wrapped around. In the illustrated example, the roll 26C is a drive roll, and the roll shaft 23 of the drive roll 26C is driven by the drive system of the machine to cause the divided belts 25A to 25J to run continuously. Further, the roll 26A is designed to freely rotate around the roll shaft 24.

First winding belt 11 and second winding belt 12
and are juxtaposed in a state where they are opposed to each other by a predetermined length range (the range indicated by reference numeral L in FIG. 1, for example, L=40 cm). The second take-up belt 12 is configured to run continuously in the direction opposite to the running direction of the first take-up belt 11 (in the direction of the arrow). A web winding portion 13 is formed between the winding belts 12 over the above length range L.

In this web winding section 13, the intervals between the inlets 13a correspond to the diameter of the winding core R and are approximately equal to the diameter (for example, about 45 mm), and the intervals between the outlets 13b correspond to the final diameter of the web wound body S. (product diameter, e.g.
from the inlet 13a to the outlet 13 so as to correspond to or be larger than 88 to 128 mm).
The interval is set to gradually increase toward b.

Further, in this web winding device 2, the running speed of the second winding belt 12 is higher than that of the first winding belt 1.
The running speed is set to be slightly slower than the running speed of 1. After the web end Qa is wound around the winding core R at the entrance 13a of the web winding section 13, the web winding body S is wound thickly from the entrance 13a side of the web winding section 13 to the exit 13b.
The running speed of the second winding belt 12 is such that the running speed of the second winding belt 12 is such that the web winding body S moves around the winding core R from the web winding section entrance 13a to the exit 13b. Predetermined length (product length)
The web can be wound up.
Note that the slower the running speed of the second winding belt 12 is compared to the running speed of the first winding belt 11, the more the web winding body S moves from the entrance 13a side to the exit 13b side of the web winding section. Although the speed increases, the running speed of the second winding belt 12 is lower than that of the web wound body S.
is from the inlet 13a side of the web winding section 13 to the outlet 13
It is preferable to set the web so that it is wound around the winding core by a predetermined length (product length) when the web reaches the outlet 13b or just before reaching the outlet 13b. For example, when the web length per product is 55 m and the distance L (Fig. 1) from the inlet 13a to the outlet 13b of the web winding section 13 is 40 cm, the running speed of the second winding belt 12 is When the running speed of the winding belt 11 is reduced by 80/5500, the web winding with the minimum diameter is achieved, with the web end being wound around the winding core R at the web winding section entrance 13a, as shown in FIG. As shown in FIG. 12, when the rotating body S moves to the web winding section outlet 13b, the length of the web product is wound around the winding core to form the web wound body S (web roll T) with the maximum diameter. Become.

Note that if the relative inclination angle of the opposing surfaces of the winding belts 11 and 12, the mutual spacing, or the running speed (or running speed difference) of the winding belts 11 and 12 can be changed as desired, Even if the diameter of the winding core R, the thickness of the web Q, the winding diameter (or winding length) of the web winding body S, etc. change, the above factors (relative inclination angle between winding belts, relative spacing , running speed or running speed difference, etc.) to accommodate all kinds or sizes of webs and web roll elements, such as thin webs (e.g. aluminum foil) and thick webs (e.g. towel paper). be able to.

The distance between the two winding belts 11 and 12 can be adjusted by horizontally moving one or both of the winding belt rolls, and the relative inclination angle can be adjusted by unequal adjustment of the winding belt rolls. This can be done by horizontal movement, and the running speed or the difference in running speed of both winding belts can be adjusted by adjusting the rotational speed of their driving rolls. In this case, if the running speed of the web itself changes as the running speed of the take-up belt is adjusted,
It goes without saying that the overall drive speed or drive cycle of the web traveling drive system and its associated devices can also be adjusted.

Note that in this embodiment, the first
Although belts are used as the and second winding members 11 and 12, in other embodiments, the first winding members 11 and 12 are belts.
Each of the second winding members can also be constructed of a roll, for example, as in the known example shown in FIG. In this case, it is necessary to provide an appropriate displacement mechanism for moving both take-up rolls toward and away from each other.

In this embodiment, the web cutting device 3 is of an air cutter type, and a first winding belt is installed at a position immediately below and adjacent to the position where the winding core R is supplied at the entrance 13a of the web winding section 13. A large number of air nozzles 3 (10 in total) eject high-pressure air from the 11 side toward the second winding belt 12 side.
4, 34... are arranged. These air nozzles 34, 34, . . . are respectively arranged in the spaces formed between the respective divided belts of the first winding belt 11, as shown in FIG. Further, each of the air nozzles 34, 34, .
The portions pre-cut by the web pre-cutting device 7 correspond to the traveling positions of the web winding sections 1 and 1, respectively.
When approaching the inlet 13a of 3, the solenoid valve 32
is opened and high pressure air from the compressor 31 passes through the air duct 33 to each air nozzle 34,
34... is now being ejected. Then, when high-pressure air is ejected from each air nozzle 34, 34..., the ejected air cuts the uncut portions X, X... of the preliminary cutting section, and the web Q
can now be completely separated. In this embodiment, the web preliminary cutting device 7
The installation position of the web winding section entrance 13a is relatively close (for example, at a distance of about 50 to 60 cm), and the fixed blade mounting shaft 75 of the web preliminary cutting device 7 is located relatively close to the web winding section entrance 13a.
It is preferable that a signal for opening the solenoid valve 32 be generated almost simultaneously with the rotation of the solenoid valve 32 . Specifically, as shown in FIG.
The second winding belt 12
roll shaft 24 (normally non-rotating as described later)
A signal from a proximity switch 39 detects when a shaft 38 that rotates together with the roll shaft 24 through a chain 30 rotates by operating a clutch 27 provided in the roll shaft 24. The solenoid valve 32 is opened for a predetermined set time (for example, 1 to 2 seconds). Further, in this embodiment, the web cutting device 3 also serves as a part of the web end winding device 5, as will be described later.

It is configured to include a core extrusion device 45 for extruding the core from the second guide section tip 44a to the web winding section entrance 13a. The winding/unloading device 43 has a total of three winding core receiving grooves 46a, 46a, 46 at equal intervals (angle interval of 120°) on the outer periphery.
It has a rotary drum 46 having a shape of a. The rotary drum 46 is intermittently rotated by an angle of 120 degrees, and when the core receiving groove 46a is open upward, a first guide is inserted into the upwardly opening core receiving groove 46a. Section 42
One core R is dropped into the core receiving groove 46a with an upward opening.

It is designed to be discharged into the guide section 44.
Incidentally, this rotary drum 46 is rotated by an angle of 120° each time the web feeding device 1 feeds out a predetermined length (product length) of the web Q from the raw fabric roll P. The outlet (tip) 44a of the second guide part 44 is an opening (for example, about 44 mm) that is very slightly smaller than the diameter of the winding core R (for example, 45 mm), and discharges from the rotary drum 46 side into the second guide part 44. The rolled core R is moved to the second guide portion 4.
It can be temporarily held at the outlet 44a of No. 4. As shown in FIG. 2, one set of core extrusion devices 45 are arranged in every other space formed between each of the divided belts 25A to 25J on the second winding belt 12 side.

A roller 49 is attached to the tip of the roller 8. This roller 49 is installed at a position projecting radially outward from the outer surface of the roll shaft 24 by a considerable distance. On the other hand, the roll shaft 24 receives power from the drive system of this machine and is connected to a clutch 27 (with a brake).
It is designed so that it can be rotated intermittently through an angle of 180°. That is, the roll shaft 24 is
Normally, it does not rotate, but as shown in FIG.
When the clutch 27 (with brake) is activated in response to a count-up signal from the rotary blade roll 10B (counting the number of rotations of the rotary blade roll 10B), power from the drive system of the machine is transmitted to the roll shaft 24 and the roll shaft 24 is rotated. 2

That is, as shown in FIG. 11, high-pressure air is ejected from each air nozzle 34, 34, . (At this time, the new core R waiting at the outlet 44a of the second guide member 44 is pushed out by the extrusion device 47, but at this time, the core R is transferred to the core rotation imparting device 100, which will be described later). Therefore, the web end (leading side end) Qa on the side of the web roll P at the cutting part is exposed to high-pressure air. Due to the biasing force, the outer surface of the core R being fed toward the web winding section entrance 13a is urged, and the core R is further rotated in the direction of the arrow (clockwise rotation direction). As a result, the web leading end Qa immediately connects to the winding core R and the second winding belt 1.

At this time, due to the frictional force between the surface of the second winding belt 12 and the surface of the winding core R, the winding core R is immediately moved (before reaching the web winding start part). You will be able to rotate it. Note that the core R pushed out from the outlet 44a of the second guide member is pushed to the web winding section 1 by the pressing member 47 while being applied with rotational force in advance as described above.
3 (winding start section 13a).

As shown in FIG.
This is to stop the rotation of the wound web roll T falling from 3b while rotating at high speed, and to enable the web roll T whose rotation has been stopped to be sent to the next process side. be. In this embodiment, the braking/feeding device 110 rotates two anti-rotation roll shaft members 111 and 112 at a position directly below and near the outlet 13b of the web winding section 13 so that the two rotation stopper roll shaft members 111 and 112 are parallel to each other and the fabricated web roll The distance E is slightly smaller than the diameter D of the web roll T (preferably, the diameter D of the web roll T is about 110 mm)
The rotation stopper roll shaft members 111,
One of the roll shaft members 111 of 112 is fixed,
The other roll shaft member 112 is slowly rotated by a motor 113 (see FIG. 7) in a direction in which the inner surface moves downward. Therefore, the web roll T that has finished winding the web and falls from the outlet 13b of the web winding section 13 while rotating at high speed,
First, the rotation is stopped by being sandwiched between the two rotation stopper roll shaft members 111 and 112, and then one rotation stopper roll shaft member 112 is slowly rotated in the direction of the arrow. The web roll T held between the shaft members 111 and 112 is sent downward while being elastically deformed. In addition, both anti-rotation roll shaft members 111, 11
If the surface of the web roll T is made of a material having a large coefficient of friction such as rubber, the rotation stopping action and downward sending action of the web roll T will be improved. In other embodiments, both rotation stopper roll shaft members 111, 112
Both may be slowly and continuously rotated so that the surfaces facing each other move from top to bottom.

A tilting table 115 is installed below the braking/feeding device 110, and the web roll T that falls onto the tilting table 115 from the braking/feeding device 110 side rolls downward on the tilting table 115. Then, it is sent to the next process (for example, a web end gluing process).

Various timing adjustment devices such as the web preliminary cutting timing adjustment device 8, the core supply timing adjustment device 6, and the web cutting timing adjustment device 9 correct their respective timings in response to changes in the web feeding speed (web winding speed). It is for the purpose of That is, the proximity switch 79 (FIG. 3) counts up and generates a signal, and in response to this signal, the clutch 27 is actuated to cut the web pre-cutting device 7 (cam device 76) and core supply device 4 (core supply device 4). Extrusion device 45), web cutting device 3 (electromagnetic valve 32)
etc. is operated (response time) is constant, but if the web feeding speed is changed, the length of the web Q that travels within the above response time will vary, and as described above. If the various timing adjustment devices 8, 6, and 9 (particularly the core supply timing adjustment device 6) are not provided, the web preliminary cutting timing, core supply timing, web cutting timing, etc. will be shifted. For example, when the web feeding speed is changed from low speed to high speed, the web preliminary cutting position may shift to the rear side (toward the original roll) in the web running direction, or the fixed blade 7
3 ejection timing is delayed and preliminary cutting parts Y, Y...
is no longer formed over the entire width, the core is supplied with a delay after the web preliminary cutting position passes the core supply position, and furthermore, the electromagnetic When the valve 32 is opened and the web feeding speed is changed from high speed to low speed, contrary to the above, the web preliminary cutting position shifts to the front side in the web running direction, and the web preliminary cutting position shifts to the winding core. The winding core is supplied before reaching the supply position, and the solenoid valve 32 is opened before the web preliminary cutting position reaches the cutting position by the air nozzle 34, so that the web end Qa is successfully wound around the winding core R. The problem arises that it cannot be attached.

In this embodiment, the web preliminary cutting timing adjustment device 8, the core supply timing adjustment device 6, and the web cutting timing adjustment device 9 extend and retract the cylinder 122 with a positioner based on a signal from a speed detection device 120 that detects the web feeding speed. By changing the phase of the proximity switch 79 and changing the timing at which the count-up signal is issued from the proximity switch 79, the actuation timing of the clutch 27 is adjusted to adjust the web preliminary cutting timing (the actuation timing of the cam device 76). , core supply timing (operation timing of the core extrusion device 45), and web cutting timing (operation timing of the solenoid valve 32).

In this embodiment, the speed detection device 120 employs what is commonly called a tachogenerator, which can detect the rotation speed of a rotating shaft or the like and convert the rotation speed into an electrical signal such as voltage or current. In the illustrated example, the rotational speed of the rotary blade roll 72 of the web preliminary cutting device 7 (driven by the main machine drive system including the web feeding device 1) is detected.
The rotational speed reading signal (electrical signal) from this speed detection device 120 is transmitted to the cylinder with a positioner 122 via an electro-pneumatic converter 121 (converts the magnitude of voltage or current to the magnitude of air pressure). The expansion/contraction position of the cylinder 122 is determined by the magnitude of the input air pressure. cylinder 1
One end of a chain 124 is connected to the rod 22, and the chain 124 is connected to a sprocket installed discontinuously and concentrically with the rotary blade roll 10B of the perforation device 10. It is wrapped around 125. Proximity switch 79 is attached to sprocket 125, and as cylinder 122 expands and contracts, as shown in FIG. 5, sprocket 125 is rotated and the phase of proximity switch 79 is changed. On the other hand, a shielding plate 126 is attached to the shaft of the rotary blade roll 10B, and the shielding plate 126 operates the proximity switch 79 once every time the rotary blade roll 10B rotates once. Therefore, when the drive speed (web feeding speed) of the drive system of this machine changes, the proximity switch 7 changes accordingly.
9 changes, thereby causing proximity switch 7
It becomes possible to change the timing of the count-up signal issued from 9. For example, when the drive speed of the drive system of this machine is increased, the tachogenerator 120,
Through the electro-pneumatic converter 121, the cylinder 122 is extended by a predetermined length commensurate with this, as shown in FIG. 5, and the position of the proximity switch 79 is moved in the clockwise rotation direction (advance direction). This acts to speed up the count-up signal emitted from the proximity switch 79, and conversely, when the drive speed of the drive system of the machine is reduced, the count-up signal emitted from the proximity switch 79 is accelerated. It acts to delay. When the timing at which the count-up signal is issued is advanced, the activation timing of the clutch 27 is advanced, the web preliminary cutting timing (the activation timing of the cam device 76) is advanced by an appropriate amount of time, and the drive speed of the drive system of the machine is increased. Even though the web Q has been cut by a predetermined length, the web Q can be pre-cut at a position where it is let out by a predetermined length. In addition, even when the drive speed of the drive system of the present machine is reduced, it goes without saying that the web Q can be preliminarily cut at a position where it has been let out by a predetermined length.
On the other hand, when the actuation timing of the clutch 27 is advanced, the core extrusion device 45 also starts operating earlier, and when the pre-cut position of the running web Q approaches exactly the core supply position. Then, the core R waiting at the second guide member outlet 44a is pushed out. In this case, the winding core R is
The pre-cut portion of the web should not come into contact with the web Q until it passes through the core supply position (the glue attached to the outer surface of the core R will not adhere to the trailing end Qb of the web Q). ),
As shown in FIG. 11, the web is wound so that the web is cut immediately after the pre-cut portion of the web passes the core supply position, and the leading edge Qa of the web comes into contact with the glue-attached portion of the outer surface of the core R. The timing of core supply is adjusted.

On the other hand, another cylinder 132 with a positioner is connected to the electropneumatic converter 121, as shown in FIG. This other cylinder 132 with a positioner is for changing each phase of the proximity switch 39 for operating the solenoid valve 32 of the web cutting device 3 and the proximity switch 29 for operating the brake of the clutch 27.
The timing of the signals emitted from the proximity switches 39, 29 is adjusted by changing the phase of each proximity switch 39, 29 attached to each gear 135A, 135B by moving the rack 134 connected to the rod 134 forward or backward. I'm trying to do what I can.
That is, when the drive speed of the drive system of this machine is high, the cylinder 132 expands and each gear 135A, 135B
is rotated clockwise and each proximity switch 39, 29
are moved in the clockwise rotation direction (advance angle direction), and when the clutch 27 is operated, an opening operation signal to the solenoid valve 32 is issued from one of the proximity switches 39 earlier by the advance angle. When the web is pre-cut, the air nozzle 34
), and the clutch 27 is activated earlier by the advance angle from the other proximity switch 29.
A braking signal is generated to stop the core extrusion device 45 at a position rotated by exactly 180 degrees. If the drive speed of the drive system of this machine is slow, each of the proximity switches 39 and 29 will retard the timing accordingly, so that the high-pressure air jet timing from the air nozzle 34 is delayed by the web preliminary cutting position. In addition, the timing at which the braking signal to the clutch 27 is issued is delayed accordingly.

In this embodiment, the web preliminary cutting timing adjustment device 8, the core supply timing adjustment device 6, and the web cutting timing adjustment device 9 share common parts such as a speed detection device 120, an electro-pneumatic converter 121, and a clutch 27. Although these timing adjustment devices 8, 6, and 9 are operated in conjunction with each other, they may be provided independently. Also, in other embodiments, the web pre-cutting device 7 can be omitted. Furthermore, in other embodiments, the web cutting timing adjustment device 9
It can also be omitted. In that case, the web length per product varies as the web feed speed changes, but this is acceptable as long as the error in web length is within the permissible range of the web length per product. Note that even if the web cutting timing adjustment device 9 is omitted, the core supply timing can be changed to correspond to the leading end of the web to be cut by the web cutting device 3 in response to changes in the web feeding speed. Of course, there is a need to encourage them.

Next, to explain the direction and operation of manufacturing a web roll using the illustrated web roll manufacturing apparatus, first, the ends of the webs are pulled out from the two raw rolls P, P, and each web is stacked in two sheets. , as shown in Fig. 1, and the leading end of the web Q as shown in Fig. 8.
Qa is wound around the winding core R at the web winding section entrance 13a. In this state, the core R around which the web tip Qa is wound is supported at three points by the first winding belt 11, the second winding belt 12, and the extrusion member 47 of the core extrusion device 45. . When the entire web roll manufacturing apparatus starts operating in this state, the web is continuously fed out from the two original rolls P, P by the web feeding devices 1, 1, while the inlet 13a of the web winding section 13 At this point, the web Q comes to be wound around the winding core R. At this time, by making the running speed of the second winding belt 12 slightly slower than that of the first winding belt 11, the web winding body S is moved to the web winding section as shown in FIG. At 13, the roll becomes thicker and gradually moves from the inlet 13a side to the outlet 13b side. When the web Q of a predetermined length (product length) is unwound from the raw rolls P, P, a count-up signal is issued from the proximity switch 79, the clutch 27 is operated, and the web Q is unwound as shown in FIG. The rotary blade mounting shaft 75 of the preliminary cutting device 7 is operated, and the double-edged tools 73 and 74 come into contact with each other.
As shown in FIG. 7, the web Q is pre-cut. At that time, the outlet 4 of the second guide part 44
The new winding core R held by 4a is pushed out by the extrusion member 4.
7 to the web winding section entrance 13a side, but the winding core R is pushed out to the web winding section entrance 13a side by the leaf spring 101.
The web is pressed against the upper surface of the winding belt 12 and rotated in advance before being supplied to the web winding section entrance 13a. When the pre-cut portion of the web Q approaches the web winding section entrance 13a, a signal from the proximity switch 39 causes the solenoid valve 32 to
is opened and high-pressure air from the compressor 31 is ejected from each air nozzle 34, 34, . . . toward the pre-cut portion (uncut portion is cut off. Next, the cut web end Qa on the raw roll side is blown toward the outer surface of the winding core R by the biasing force of the high-pressure air, and the winding core R is rotated clockwise. By continuously running the take-up belt 12 and the first take-up belt 11, the web leading end Qa
is reliably wound around the core R. On the other hand, the cut web end (trailing side end) Qb on the side of the web winding body is wound up as it is on the side of the web winding body S, which has moved to the vicinity of the outlet 13b of the web winding section 13. A roll T is formed. The web roll T thus formed is caused to move the web winding section 13 further toward the outlet 13b,
When the web roll T can no longer be held between the first and second winding belts 11 and 12, the web roll T is discharged downward from the web winding section outlet 13b, and the braking/feeding device 110 After passing between the rotation stopper roll shaft members 111 and 112 (FIGS. 1, 6, and 12) and falling onto the table 115, the web is sent to the next process (for example, a web end gluing process). Note that when the web roll T is discharged downward from the winding section outlet 13b, the web roll T is rotating at high speed, but the web roll T is rotated due to the frictional force between the rotation stopper roll shaft members 111 and 112. The rotation is immediately stopped, and after the rotation is stopped, one of the rotation stopper roll shaft members 112 is slowly rotated, so that the web roll is held between both rotation stopper roll shaft members 111 and 112. T can be reliably dropped onto the table 115.

As mentioned above, this web roll manufacturing device is capable of manufacturing web rolls T one after another while the devices (web feeding device, web winding device, etc.) are in continuous operation without interrupting the operation. be. Further, according to the continuous operation type web roll manufacturing apparatus of this embodiment, in order to move the web wound body S from the inlet 13a side to the outlet 13b side while increasing the roll thickness in the web winding section 13,
First winding belt 11 and second winding belt 12
It is only necessary to continuously run each of them at a fixed position under the above-mentioned conditions, so the configuration for that purpose is shown in FIG.
(The upper and lower presser rolls 213, 214 and the second take-up roll 212 are connected to the first take-up roll 211 in the web roll manufacturing apparatus shown in FIG. Displacement actuation mechanism 2 for moving in the approaching/separating direction
15 can be omitted).

In addition, in this web roll manufacturing apparatus, even when the web feeding speed changes, various timing adjustment devices such as the web preliminary cutting timing adjusting device 8, the core supply timing adjusting device 6, and the web cutting timing adjusting device 9 are used to adjust the web preliminary cutting timing. Cutting timing, core supply timing, and web cutting timing can be automatically corrected.
Web winding work is performed smoothly.

(Effects of the invention) The continuous operation type web roll manufacturing apparatus of the invention has the following features:
It has the following effects. That is, the second winding member 12 is caused to continuously travel in a direction opposite to the running direction of the first winding member 11 with respect to the first winding member 11 that is caused to continuously travel at a speed equal to the web unwinding speed. are arranged side by side to form a web winding part 13 of a predetermined length between the first winding member 11 and the second winding member 12, and furthermore, the web winding body is connected to the web winding part entrance 1.
3a side to the web winding section outlet 13b side, the leading end of the web Q is moved around the core R at the entrance 13a of the web winding section 13. When part Qa is wound, the web winding body S is moved from the entrance 13a side of the web winding part 13 toward the exit 13b side while winding up the web Q that is successively unwound and increasing the winding thickness. Web winding section 1
A new next winding core R can be supplied to the inlet 13a of No.3. Further, when the web Q of a predetermined length (product length) is wound around the winding core R in the web winding section 13, the web cutting device 3 cuts the web Q while it is running.
After the trailing end Qb of the web is cut and wound around the web S, the web is discharged from the outlet 13b of the web winding section 13. The leading end Qa is connected to the web end winding device 5 at the web winding section entrance 13a.
The winding core R is then wound around the newly supplied winding core R.

Therefore, according to the continuous operation type web roll manufacturing apparatus of the present invention, web rolls can be manufactured continuously without interruption of the web winding action by the web winding device 2, and the web winding action of the conventional web winding action is improved. Compared to the intermittent web roll manufacturing method, efficiency is significantly improved, and since each device (web feeding device, web winding device, etc.) is operated continuously, wear and tear on the device is reduced. effective.

Further, according to the present invention, the web winding section outlet 13b
The braking/feeding device 110 is capable of stopping the rotation of the web roll T discharged from the web roll T and sending it to the next process side. Since they are arranged in parallel, the construction is simple, and the 13th
As in the known example shown in the figure (Japanese Unexamined Patent Publication No. 57-77147), there is no need to adjust the operation timing of the pressing member to match the release timing of the web roll that is released while rotating. It has the effect of being canceled.
