DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for unloading a long material such as a paper web, a plastic film, and a metal foil, and an apparatus for winding the long material using the method. It is.

[0002]

2. Description of the Related Art A web roll of a long material such as a paper web produced by a paper machine is rewound and shipped as a take-up roll having a desired width and length. A winding device that generates a winding roll is mainly composed of two drum rolls (winding drums), and a core of the winding roll is installed on these drum rolls. The long material passed from below between the two drum rolls passes through a nip formed by the drum roll and the core, and is wound on the core. When the drum roll rotates the core, a take-up roll is generated.

[0003] At the start of winding, it is necessary to attach the start end of winding of the long material to the core. Pasting has conventionally been performed as shown in FIG. New core 26, core 26
Then, the core 26 is rotated by the two drum rolls 22 and 24 to send the double-sided tape T to the nip N1. At the same time, the paper web W is sent to the nip N1 such that the position of the start end of the paper web W matches the position of the double-sided tape. The paper web W is pressed against the double-sided tape T by the nip N1, and the paper web W is attached to a new core.

When the winding roll is completed, the long material is cut. At that time, conventionally, the long material was cut using a cutter for cutting the long material. The cut-up winding roll can be rolled and sent to a terminal tape application device. In a long material terminal tape application device, a long material terminal is fixed to a winding roll by applying a double-sided tape or a single-sided tape.

[0005]

However, the sticking method shown in FIG. 9 has a problem that the paper web W is peeled off when the double-sided tape is not accurately applied to the start end of the paper web W. . Further, there is a problem that the tape adheres to the drum roll, and the tape wraps the paper around the drum roll. This will be described with reference to FIGS.

As shown in FIG. 10, a paper web W is formed at a nip N1.
When the gap L between the start end of winding the paper web W and the position of the double-sided tape T is large when the paper web W is bonded to the double-sided tape T, the leading end of the paper web W is moved in the first nip N2 after bonding. Bends without passing through the nip N2. In this case, as shown in FIG. 11, the bent paper web W generates a force for peeling the paper web W from the double-sided tape T. As a result, the paper web W separates from the double-sided tape. Since this problem is particularly likely to occur when the paper web is a cardboard web, it is strongly required that the position of the double-sided tape be accurate when winding up the cardboard web.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method of unloading a long material which can solve the above-mentioned drawbacks of the prior art and can reliably attach the start end of the winding of the long material to a core. And

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, when the end of winding of a long material is located in front of the winding drum, the end of the winding is located near the end. A double-sided tape is applied to both the area closer to the end end and the area farther from the end when viewed from the winding drum, and the long material is applied in the width direction of the long material between the two areas where the double-sided tape is applied. A partially cut portion is provided, and when the cut portion is located in front of the nip, the long material is cut at the cutting portion, and the long material is cut by the double-sided tape at the winding end end of the cut long material. The length member is fixed to a wound winding roll, and the long member is fixed to a new winding roll core by a double-sided tape at a winding start end of the length member.

According to the present invention, since the double-sided tape is accurately adhered to the vicinity of the cut portion which is the winding start end, the winding end of the long material can be securely adhered to the core. It is. In the prior art, since the double-sided tape is stuck to the new core, the tape is misaligned. However, in the present invention, since the double-sided tape is stuck directly to the long material, no misalignment occurs.

Further, according to the present invention, when a long material is cut at a cutting portion at a position before the nip, a portion of the long material at a position farther from the nip than the double-sided tape is fixed at this position. Then, by moving the wound-up winding roll, the long material is cut, and after the cutting, the winding roll is caused to travel through the traveling portion for the winding roll, thereby completing the winding of the cut long material. With the double-sided tape at the end, the long material is fixed to the wound take-up roll, a new take-up roll core is placed on the take-up drum, and a nip is formed with the take-up drum, By passing the cut other long material, the long material may be fixed to a new winding roll core by the double-sided tape at the winding start end of the long material.

In this case, since the double-sided tape is accurately adhered to the vicinity of the cut portion, which is the start end of the winding, the start end of the winding of the long material can be securely adhered to the core. In the present invention, since the double-sided tape is directly adhered to the long material, no displacement occurs. Furthermore, the end of the rolled-up long material can be fixed to the winding roll with a double-sided tape simply by running the rolled-up winding roll on the traveling section. Therefore, there is no need to provide a terminal tape sticking device according to the related art.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an apparatus for winding a long material according to the present invention. In this embodiment, elements not directly related to the present invention are omitted, and the same elements are denoted by the same reference numerals. In the following examples, a paper web is used as a long material, but the present invention can be applied to other long materials such as a plastic film and a metal foil.

FIG. 1 is an overall configuration diagram of a long material winding device according to the present invention. The winding device 10 mainly includes a rewinding unit 11, a winding unit 20, and an unloading unit 40. In the rewinding section 11, the paper web W is rewound from the raw roll 14 installed on the unwind stand 12. Each guide roll 16 guides the paper web W, the slitter 18 cuts the paper web W into a desired width, and then the paper web W is sent to the winding unit 20 via the tape application device 46.

When the winding of the paper web W is stopped and the running of the paper web W is stopped in order to perform the work of applying the double-sided tape T to the paper web W and cutting the paper web W, the tape application device 46 A tape T is attached to the lower surface of the paper web W.

The tape applying device 46 is a cutting section (perforation) for partially cutting the paper web W in the width direction of the paper web W.
Also serves as a perforation processing device. This device 46
Perforates the paper web W in the middle of the two double-sided tapes attached before and after the end end of the paper web W. When performing perforation, the vacuum device box 38 sucks the paper web W and fixes the paper web W. During winding, the tape application device 46 and the vacuum device box 38 do not contact the paper web W.

Further, the pinch roll 44 is located below so as not to come into contact with the paper web W during the winding of the paper web W, and moves upward when the winding is completed to move the paper web to the guide roll 16. Pressing to prevent the paper web W from sagging during tape application and perforation processing.

In the winding section 20 following the tape attaching device 46, 2
Two drum rolls 22 and 24 are rotatably installed.
A core 26 is mounted on these drum rolls 22,24.
A nip N is formed by the rear drum roll 22 and the core 26. The counter-clockwise rotation of the rear drum roll 22 causes the core 26 to rotate clockwise. After traveling along the outer circumference of the winding drum, the paper web W is wound around the core 26 through the nip N, and a winding roll 28 is formed.

The front drum roll 24 may be rotated in synchronization with the rear drum roll 22, or may be freely rotatable. Drum rolls 22 and 24 have
A brake is provided to apply a brake to the drum rolls 22, 24 when the take-up rolls 28 are unloaded from the drum rolls 22, 24, thereby preventing the drum rolls 22, 24 from rotating.

A small-sized rider roll 29 comes into contact with the take-up roll 28 from above, which weights the take-up roll 28 and ensures that the take-up roll 28 comes into contact with the drum rolls 22 and 24. .

The paper passing roll 30 is separated from the paper web W during winding. After the winding is completed, the portion of the paper web W to which the double-sided tape has been applied is sent to a predetermined position before the nip N, and then pressed against the rear drum roll 22.
Then, the portion of the paper web W located farther from the nip N than the perforation is fixed, so that the paper web W is cut at the perforation. Also, at the time of paper passing, the rotation of the rear drum roll 22 and the pinch force of the paper passing roll 30 cause
Also plays the role of a web paper roll.

The extruding arm 32 is rotatable about a rotating shaft 34. After the winding roll 28 is completed, the pushing arm 32 is rotated.
The take-up roll 28 is pushed out toward the unloading section 40 with the paper web W held down by the 30 and the rear drum roll 22. As a result, the paper web W can be cut at the perforated position.

The push-out arm 32 further moves the wound take-up roll 28 so that the take-up roll 28 runs on the table 36 of the unloading section 40. As a result, the end of the paper web W is fixed to the winding roll 28 by the double-sided tape at the winding end of the cut paper web W.

Thereafter, a new take-up roll core 26 is placed on the drum rolls 22 and 24 and is brought into contact with the rear drum roll 22 to form a nip N. Next, drum rolls 22 and 2
The core 26 is rotated by 4 so that the starting end of the cut paper web W passes through the nip N. At this time, since the nip N presses the start end of the paper web W against the core 26, the start end of the paper web W is fixed to the new take-up roll core 26 by the double-sided tape T at the start end. At this time, in order to guide the paper web W and prevent the paper web W from falling down, the paper passing plate 42 along the outer periphery of the rear drum roll 22 is provided.
Is provided.

Next, the long material winding device according to the present invention will be described in detail with reference to FIGS. FIG. 2 shows the tape application device 46 and the vacuum device box 38 as viewed in the AA direction of FIG. The tape attaching device 46 includes a rail 48 provided between two columns (not shown) provided on both sides of the winding device 10.
The upper side travels in the width direction of the paper web W in the direction of the arrow S in the figure, and the double-sided tape T is applied.

A traveling plate of the tape applying device 46 is supported on a rail 48, and a motor 52 is mounted on one end of the rail 48, and a sprocket 54 is mounted on the other end. The traveling plate 50 is driven by a chain 56 wound around a motor 52 and a sprocket 54. When the motor 52 is rotated, the traveling plate 50 travels on the rail 48 in the width direction of the paper web W.

A tape-attached magazine 62 is attached to the traveling plate 50 via parallel links 58 and 60, and the tape-attached magazine 62 is lowered by expanding and contracting a cylinder 64 connected to one end of the parallel link 58. , Can be raised. Raise the tape-attached magazine 62 to raise the paper web W
, The double-sided tape T is stuck to the paper web W only during that time, and when the tape sticking magazine 62 is pulled down, the double-sided tape T is torn off from the boundary between the stuck portion and the non-stuck portion, and the stuck double-sided tape T Only remains on the paper web W. The double-sided tape T is unwound from the master roll 66 together with the backing paper, and is positioned
Only the backing paper adheres to the paper web W, and the backing paper separated from the double-sided tape T is wound on the backing paper winding roll 74 via the outer periphery of the parent winding 66.

Regarding the position where the double-sided tape T is stuck on the take-up roll 28, both ends in the width direction of the take-up roll 28, for example, 5
The double-sided tape T is not attached to a region of not less than mm, preferably a region of about 30 to 50 mm. If the end of the double-sided tape T hangs down from the end of the take-up roll 28, the value of the product will be reduced. If the terminal is attached to the slit position of the take-up roll 28, it will break when unwinding the paper in a later process. This is because it is preferable to stick the paper with a slight distance from the roll end and the slit position, as this may cause troubles such as sticking of the adhesive to the paper end or the unwound paper end.

Regarding the application position of the double-sided tape T from the winding end end or the winding start end, for example, an area of 5 mm or more, preferably about 10 mm from the winding end end or the winding start end, Do not attach T. This is because if the double-sided tape is in the immediate vicinity of the paper edge, the adhesive material protrudes due to the nip pressure when the take-up roll rolls on the traveling platform or the like.
Further, when performing the perforation, the more the adhesive material adheres to the perforation blade, the more the double-sided tape is in the immediate vicinity of the paper edge.

In this embodiment, in consideration of the above-mentioned conditions for the position of the double-sided tape T in the width direction of the take-up roll 28, the paper web W corresponding to a position 30 mm from one end of the take-up roll 28 is taken into consideration.
The tape application magazine 62 is raised at the position of, and the tape application magazine 62 is lowered at the position of the paper web W corresponding to the position 30 mm from the other end of the winding roll 28.

After raising the tape sticking magazine 62 at the position of the paper web W corresponding to a position 30 mm from one end of the take-up roll 28, the double-sided tape T together with the backing paper, as shown by the arrow in FIG. It is fed out from the master winding 66 attached to the sticking magazine 62. Double-sided tape T is a guide roll
After 68, it is pressed against the paper web W by the guide roll 70. At this time, the mount and the double-sided tape T are separated. Only the backing sheet passes through the guide roll 72 and the outer periphery of the master winding 66, and is wound on the backing sheet winding 74.

The position where the tape is applied on the paper web W is shown in FIG.
As shown in (A), it is before and after perforation M (this is the winding end of paper web W and the winding start end). As shown in FIG. 12, the master winding 66 has two double-sided tape rolls so that two double-sided tapes T can be simultaneously attached to the paper web W. FIG. 12A shows a master winding 66 of a type in which two tape rolls are formed on one tape core 90. FIG. 12B shows two tape cores 9.
One tape roll is formed on each of the tape rolls 4, and two tape cores 94 are fixed to one spacer 92 to form a master winding 66 of a type in which two tape rolls are integrated.

A perforation roller 76 for performing perforation is also attached to the traveling plate 50 via a link 78. The perforation roller 76 is a cylinder 80 attached to a link 78.
With this, it descends and rises. Perforation processing roller 76
Rises at one end of the paper web W, travels to the other end, and then falls at the other end. Then, the perforation processing roller 76 travels over the entire width of the paper web W while being pressed against the paper web W by the cylinder 80, and perforates the paper web W. It is preferable that the perforation is provided in the center of the two double-sided tapes T.

During tape application and perforation, the vacuum device box 38 sucks the paper web W to prevent the paper web from becoming loose. The vacuum device box 38 is attached to the above-described column via a screw shaft (not shown), and can be moved vertically by driving the screw shaft by a motor (not shown). When the winding device 10 stops, the vacuum device box 38 is lowered to the pass line of the paper web W. After the descent, the internal cavity of the vacuum device box 38 is set to a negative pressure by a negative pressure source (not shown).

As shown in FIG. 3, a large number of suction holes 82 are formed in the vacuum surface of the vacuum device box 38, and the internal cavity 84 has a vacuum structure connected to a negative pressure source such as a vacuum pump. ing. FIG. 3 shows the BB of FIG.
A cross section is shown, showing how the paper web W is cut between the two double-sided tapes T by the perforation processing roller 76.
A concave portion 86 is provided in a portion of the vacuum device box 38 facing the perforation processing roller 76 in a width direction of the paper web.

After the double-sided tape application and the perforation are completed, the internal cavity 84 is returned to normal pressure, and the vacuum device box 38 is raised by the screw shaft and the motor before the paper web W starts running. The length in the width direction of the vacuum device box 38 is slightly larger than the length of the entire width of the paper web W.

The operation of the long material winding device according to the present invention having the above-described structure will be described in detail. As shown in FIG. 1, the paper web W is unwound from the unwind stand 12, passed through each guide roll 16 and the slitter 18, and taken up by the winding unit 20.
To reach. During winding, the pinch roll 44, the tape application magazine 62, and the paper passing roll 30 are located below, and the vacuum device box 38 is located above, and they do not contact the paper web W.

In the winding section 20, the paper web W is passed between the two drum rolls 22 and 24 from below along the outer periphery of the rear drum roll 22. Then, the paper web W sent upward passes through the nip N and is wound clockwise on the winding roll 28.

When the winding roll 28 is completed, the drum roll
The webs 22 and 24 are stopped, and the web W is pressed and held by the paper passing roll 30 provided thereunder. Further, the vacuum device box 38 is moved downward by driving the screw shaft with a motor, and starts vacuuming the paper web W. The pinch roll 44 moves upward and clamps the paper web W to prevent the paper web W from loosening.

Next, the motor 52 is driven to move the tape application device 46 shown in FIG. 2 rightward in FIG. 2 by the chain 56 from the standby position to the tape application start position. Parallel link by cylinder 64 at tape application start position
By rotating 58 and 60, the tape-attached magazine 62 is raised, and the guide roll 70 on the tape-attached magazine 62 is pressed against the paper web W. At this time, the guide roll 70 comes to the tape sticking start position (the position of the paper web W corresponding to a position 30 mm from one end of the winding roll 28). In this state, while moving the tape application device 46 in the direction of the arrow S, the take-up board 74 is driven to feed out the double-sided tape T from the master winding 66, and the double-sided tape T is applied.

Immediately before the perforation processing roller 76 reaches the end in the width direction of the paper web W, the tape application device 46 is temporarily stopped. The link 78 is rotated by the cylinder 80 to raise the perforation processing roller 76. Next, the running of the tape application device 46 is restarted, and the paper web W is perforated.

When the guide roll 70 of the tape application device 46 reaches the tape application end position (the position of the paper web W corresponding to a position 30 mm from the other end of the winding roll 28), the tape application device 4
6 is stopped, the tape-adhering magazine 62 is lowered, and the double-sided tape T is cut. When it comes to the position of the paper web W corresponding to a position 30 mm from one end of the next take-up roll 28, the tape application magazine 62 is raised again to resume the tape application. This is repeated below.

On the other hand, the perforation processing roller 76 is moved up to the end of the paper web W in a raised state, and the tape application device 46 is stopped immediately after the perforation processing roller 76 passes through the end. At this position, the perforation processing roller 76 is lowered.

As a result, the double-sided tape T is wound on the winding roll 28.
Is affixed except for the position of the paper web W corresponding to a position 30 mm from both ends of the paper web T, and is perforated over the entire width of the paper web T.

After the tape application and the perforation are completed, the tape application device 46 is moved to the standby position at the left end in FIG. The vacuum device box 38 is raised by a screw shaft and a motor. The pinch roll 44 and the drum rolls 22 and 24 are rotated at the same speed, and the portion of the paper web W to which the double-sided tape T is applied is sent to just before the nip as shown in FIG. Stop 22,24.
By rotating these rolls 44, 22, and 24 at the same speed, the perforation is not cut because no tension is applied to the perforation to pull the paper.

Next, the paper web W is cut at the perforation by performing a normal unloading operation as follows.
As shown in FIG. 5, the paper passing roll 30 is raised, and the paper web W is sandwiched between the paper passing roll 30 and the rear drum roll 22. A brake is applied to the front drum roll 24 so that the front drum roll 24 does not rotate. Extruded arm 32
Push the take-up roll 28 forward. The paper web T is cut at the perforation by the rotational force of the winding roll 28. One of the two double-sided tapes T is attached to the take-up roll 28 near the end of the paper web W. The other side of the double-sided tape T is attached near the start end of a new winding. The starting end is a paper passing plate 42 that is both a paper passing plate and a paper fall prevention plate.
Falling to the floor is prevented.

As shown in FIG. 6, the take-up roll 28 is pushed out beyond the front drum roll 24, and is rotated on the table 36. When the take-up roll 28 rotates on the table 36, the paper end of the take-up roll 28 is pressed by the take-up roll 28 and the table 36, so that the double-sided tape T adheres to the take-up roll 28. As a result, a terminal tape attaching device for adhering the paper end of the take-up roll with tape, which is required in the related art, becomes unnecessary. The take-up roll 28 with the paper end adhered is sent to the next step.

On the other hand, a new winding core 26 is placed on the drum rolls 22 and 24 for the next winding. Put the rider roll 29 on the core 26. When winding is started in this state, the starting end of the paper web T is moved to the core 26 at the nip N.
Is securely bonded.

Since the double-sided tape T is accurately adhered to a predetermined position near the start end, unlike the prior art, the double-sided tape T is not adhered to a position shifted from the start end. As a result, the paper web W does not peel off from the core. The reason why the double-sided tape T can be accurately adhered to a predetermined position near the starting end is that the double-sided tape T is directly adhered to the paper web W and the paper web W is subjected to a perforation process for determining a cutting position. This is because it is performed for In particular, in this embodiment in which the tape applying device and the perforation processing roller are mounted on the same traveling plate, the relative positional relationship can be easily and accurately set.

In the above embodiment, perforations are provided in the cut portion of the paper web. However, in the cut portion of the paper web, processing other than perforations, for example, small holes are arranged in a row in the width direction. May be dawn.

In this embodiment, the perforation M is shown in FIG.
As shown in (A), it is provided between two double-sided tapes T, but the present invention is not limited to this. That is, as shown in FIG. 8 (B), one double-sided tape T is applied, and when viewed from the traveling direction D of the paper web W, the double-sided tape T
The perforation M may be inserted immediately after. After the perforation M is formed, the end of the winding roll 28 can be bonded with the double-sided tape T by cutting the paper web W as shown in FIGS. Therefore, a terminal tape sticking device for bonding the paper end of the take-up roll with a tape, which is required in the related art, becomes unnecessary. The bonding of the starting end of the paper web to the new winding core is performed according to the prior art.

Specifically, the method shown in FIG. 8B will be described. When the end of winding of the long material is located before the nip,
Attach the double-sided tape to the end end, and in the vicinity of the position where the double-sided tape is applied, and at a position farther from the nip than the position where the double-sided tape is applied, partially apply the long material in the width direction of the long material.

For this purpose, when the end of the winding of the long material is located just before the nip, a tape applying means for applying a double-sided tape to the end of the long material winding device, In the vicinity of the given position, at a position farther from the nip than the position where the double-sided tape is stuck, in the width direction of the long material, a cutting unit that provides a cutting portion that partially cuts the long material, A fixing means for fixing a portion of the long material at a position farther from the nip than the cutting portion, and when the long material is fixed by the fixing means, move the wound take-up roll, and in the cutting portion, A moving means for cutting the long material, and a traveling section on which a winding roll wound up after the cutting travels. Then, when the take-up roll travels on the traveling section, the long material is fixed to the wound take-up roll by the double-sided tape at the winding end end of the cut long material.

Further, as shown in FIG. 8 (C), one double-sided tape T is applied, and viewed from the traveling direction D of the paper web W,
The perforation M may be inserted immediately before the double-sided tape T. After the perforation M is formed, the paper web W is cut as shown in FIGS. 4, 5, 6, and 7, so that the starting end of the paper web W is securely connected to the new winding core 26 at the nip N. Adhered to. Since the double-sided tape T is accurately attached to a predetermined position near the start end, unlike the related art, the double-sided tape T is not bonded to a position shifted from the start end.
As a result, the paper web W does not peel off from the core.
The bonding of the end of the winding roll 28 is performed according to a conventional technique.

Specifically, the method of FIG. 8 (C) will be described. When the end of winding of the long material is located in front of the winding drum, the end of the long material is set in the width direction of the long material. Then, a cut portion obtained by partially cutting the long material is provided, and a double-sided tape is attached to the long material at a position near the cut portion and farther from the cut portion when viewed from the winding drum. When the double-sided tape and the cut section move to the position before the nip, the rolled-up take-up roll is moved while the long material at a position farther from the nip than the double-sided tape is fixed, and cut. In the section, the long material is cut. A new take-up roll core is placed on the take-up drum to form a nip with the take-up drum, and the other cut long material is passed through the nip, and the start end of the long material is wound. The long material is fixed to a new take-up roll core with a double-sided tape.

For this purpose, when the end of winding of the long material is located in front of the winding drum, the end of the long material is set in the width direction of the long material. Cutting means for providing a cut portion obtained by partially cutting the material, and tape applying means for applying a double-sided tape to the long material at a position near the cut portion and farther than the cut portion when viewed from the winding drum. When the double-sided tape and the cutting unit move to the position before the nip, the fixing means for fixing the portion of the long material located farther from the nip than the position of the double-sided tape, and the long material is fixed by the fixing means. And a moving means for moving the wound-up winding roll and cutting the long material at the cutting section. Then, when a new take-up roll core is placed on the take-up drum to form a nip with the take-up drum, the other cut long material is passed through the nip to wind the long material. The long material is fixed to a new take-up roll core with the double-sided tape at the take-up start end.

[0056]

As described above, according to the present invention, since a long material is cut at a position between two double-sided tapes, the double-sided tape is accurately placed at a predetermined position near the winding start end of the long material. Tape is affixed. As a result, unlike the related art, the double-sided tape is not adhered to a position shifted from the start end. And the paper web W does not come off from the core.
