Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet dividing and winding device which divides a wide belt-shaped sheet into a plurality of narrow sheets by a slitter and winds the narrow sheet around a winding core to form a sheet roll. . This sheet division winding device causes a part of the adhesive sheet piece to adhere to the surface of the winding sheet terminal portion, and the remaining part of the adhesive sheet piece adheres to the surface of the lower winding sheet, so that the winding sheet is used alone. The purpose is to obtain a sheet roll treated so as to prevent it from being rewound.

[0002]

2. Description of the Related Art Conventionally, there is a winding device described in Japanese Patent Publication No. 62-3065, for example, as a winding device capable of obtaining a sheet roll having a rolled sheet end processed.
This winding device is equipped with a winding sheet terminal processing device, and the winding sheet terminal having an adhesive tape or an adhesive or the like applied to the back surface is wound while being pressed by a pressing roller and adhered to the surface of the lower sheet. You can

However, in the sheet roll raised by the above-described winding device, the back surface of the sheet end portion is adhered over the entire width, so that it is not easy to peel it off. Therefore, it takes time and effort to peel off the sheet end when the sheet is rewound from the sheet roll. In addition, at that time, it is necessary to scratch the lower layer sheet and cut off the portion, which causes a disadvantage that many sheets are wasted. In order to prevent such an inconvenience, the seat terminal may be processed as shown in FIGS. 3A and 3B, for example.

The sheet roll R shown in FIG. 3 (A) has a hole H formed in the terminal portion E of the narrow sheet S, and an adhesive sheet piece T is adhered to the surface of the terminal portion E from above the hole H to form an adhesive sheet. A portion of the adhesive-coated surface of the piece T, which is seen through the hole H, is adhered to the surface of the lower narrow sheet S to be end-treated. Further, the sheet roll R shown in FIG. 3 (B) adheres the adhesive sheet piece T to the surface of the terminal portion E of the narrow sheet S so that a part thereof sticks out, and the adhesive sheet piece T is a narrow sheet. A portion of the terminal portion S of the sheet S protruding from the terminal portion E is adhered to the outer periphery of the narrow sheet S as the lower layer for terminal treatment.

However, since the double-sided adhesive tape or the adhesive is applied to the back surface of the sheet terminal in the above-described winding device, the sheet roll processed as shown in FIGS. 3A and 3B is used for the sheet terminal. In order to obtain it, the winding sheet terminal processing device provided in the above winding device cannot be applied as it is.
In addition, when the sheet is wound while being divided into a large number of narrow sheets with a slitter, since the space of the winding section is limited, a mechanism for processing the sheet terminal should be provided for each narrow sheet. It is difficult.

Therefore, conventionally, in order to obtain a sheet roll having a sheet end processed as shown in FIG. 3, an operator manually cuts a narrow sheet connected to each sheet roll in a sheet dividing and winding device. Then, the adhesive sheet pieces are attached to the respective winding sheet terminals.

[0007]

However, it takes a long time to manually attach the adhesive sheet pieces to the winding sheet terminals of the sheet rolls that are simultaneously wound on the winding shaft, and during that period, the winding operation is performed. Is stopped, the operating rate of the sheet dividing and winding device is reduced. In addition, rewinding of the rolled-up sheet end portion occurs before the terminal processing, and when the rolled-up rolled sheet end portion is manually wound around the sheet roll, the wound portion is displaced in the width direction and the winding state of the sheet roll There is also the inconvenience that it becomes worse.

An object of the present invention is to make a part of an adhesive sheet piece adhere to the surface of the narrow sheet end portion of a sheet roll, and to make the remaining part of the adhesive sheet piece adhere to the surface of the lower narrow sheet to form a terminal. An object of the present invention is to provide a sheet dividing and winding device capable of efficiently obtaining a processed sheet roll.

Another object of the present invention is to make a hole in the end of the narrow sheet, to adhere the adhesive sheet to the surface of the hole, and to adhere the adhesive sheet to the surface of the lower narrow sheet through the hole to make the terminal. An object of the present invention is to provide a sheet dividing and winding device that can efficiently obtain a processed sheet roll.

[0010]

In order to achieve the above object, according to the present invention, a wide band-shaped sheet is divided into a plurality of narrow sheets by a slitter, and the narrow sheets are attached to the outer periphery of a winding shaft. A sheet roll is wound around the winding core around the winding roll at a winding position, the winding shaft around which the sheet roll is wound is moved to another position, and the winding shaft equipped with a new winding core is moved to the winding position. A narrow sheet that is connected to the sheet roll is cut with a cutting blade, and the upstream cutting end of the narrow sheet is stopped at a new winding core at the winding position, and then the sheet winding is started to start the next winding. In the take-up device, between the sheet roll moved from the winding position to another position and the new winding core at the winding position, the narrow width sheet is advanced from the front surface side, and each narrow width sheet is moved to the new winding core. With a terminal treatment beam that can be approached to The advance and the back receiving beams each narrow sheet advances to the position opposite to the terminal treatment beam can be received back with, it can be withdrawn from the machine to the machine side,
An adsorption bar for adsorbing and holding an adhesive sheet piece for each narrow sheet, a holding means and a pushing-up mechanism for the adsorption bar provided on the terminal treatment beam, and an end portion of each narrow sheet as the holding means. A technical means was adopted in which a pulling-out mechanism for simultaneously pulling out the ends of the narrow sheet to just above the held suction bar and a pressing roller for pressing the outer circumference of the sheet roll were adopted.

Further, a punch for each narrow sheet can be arranged between the cutting blade of the end treatment beam and the holding means.

In order to reliably and easily supply the suction bar to the holding means in a short time, it is convenient to provide a guide member for supporting and guiding the suction bar between the holding means and the machine side. .

[0013]

In the present invention, the suction bar can be pulled out from the inside of the machine to the machine side. Therefore, on the machine side, the adhesive sheet pieces are attached to the portions corresponding to the narrow sheets on the suction bar, and the adhesive sheet pieces are attached. It can be held by adsorption with an adsorption bar. When the adhesive sheet piece for each narrow sheet is held by the suction bar, the suction bar is inserted into the machine and held by the holding means provided on the end treatment beam. The end treatment beam holding the suction bar advanced between the sheet roll moved from the winding position to another position and the new winding core at the winding position, and the narrow sheet was moved toward the new winding core. When
Each adhesive sheet piece approaches the narrow sheet and faces each other. Immediately after the cut end of the narrow sheet is pulled out right above the suction bar by the pulling mechanism, the pushing-up mechanism pushes the suction bar toward the narrow sheet. At this time, the back surface of the narrow sheet is supported by the back support beam. Therefore, the respective pressure-sensitive adhesive sheet pieces on the suction bar that have been pushed up are pressed against the cut ends, that is, the end portions of the individual narrow sheets that have been pulled out, and stick together. At this time, a part of the adhesive sheet piece covers the surface of the terminal portion. Therefore, when the winding shaft is rotated while the surface of the sheet roll is pressed by the pressing roller to wind up the narrow sheet end, the portion not covered by the sheet end portion of the adhesive sheet piece is the narrow sheet under the sheet roll. Contact with the surface and stick.

By arranging a punch for each narrow sheet between the cutting blade of the end treatment beam and the holding means, a hole is made in the end portion of the narrow sheet by this punch, and this hole is formed by the pulling mechanism. When the suction bar held by the holding means is pulled out, the suction bar can be pushed up by the pushing-up mechanism to stick the adhesive sheet piece to the surface of the hole.

[0015]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a side view of a sheet dividing and winding device to which an embodiment of the present invention is applied. The wide strip sheet S0 is rewound from a raw roll (not shown) and supplied to the slitter 1, and is divided into a plurality of narrow sheets S by the slitter 1. Each of the divided narrow sheets S reaches the winding position I via the touch roller 2 and is wound around each winding core C to become a sheet roll R. The winding core C is fitted around the outer circumference of the winding shaft 3, and the winding shaft 3 is attached to the turret 4. The touch roller 2 and the slitter 1 are supported by a swing arm 5, and the touch roller 2 retracts from the winding shaft 3 at the winding position I in accordance with the thickening of the sheet roll R.

The turret 4 has four winding shafts,
Each time the sheet roll R is wound up, the sheet roll R is rotated about the shaft 6 so that the respective winding shafts 3 are sequentially taken up in the winding position I and the sheet roll unloading position
It can be attached to II, core mounting position III, and gluing position IV. At the sheet roll unloading position II, the sheet roll R is extracted from the winding shaft 3 by the extracting arm 7, and at the winding core mounting position III, the winding core C is formed on the outer periphery of the winding shaft 3 into each narrow sheet S by a mounting mechanism (not shown). They are fitted side by side so as to correspond to each other, and at the gluing position IV, glue is applied by the gluing device 8 to each of the winding cores C fitted on the outer circumference of the winding shaft 3. When the sheet roll R is wound up at the winding position I, the turret 4 is rotated, whereby the sheet roll R at the winding position I is moved to the sheet roll unloading position II, and at the same time, the winding shaft 3 waiting at the gluing position IV. Moves to the winding position I.

As shown in FIG. 2, the rolled-up sheet roll R is at the sheet roll unloading position II, and a new core C
When the winding position I reaches the winding position I, the terminal processing beam 9 advances between them in the retracted position shown in FIG. 1, and the pressing member 10 provided along the terminal processing beam 9 moves the narrow sheet S to the new winding core C. The sheet is pressed and adhered, and the pressing roll 11 presses the outer periphery of the sheet roll R. At the same time, the back support beam 12 advances from the retracted position shown in FIG. 1 to a position facing the terminal processing beam 9, contacts the back surface of the narrow sheet S, and presser roll 1
1 holds down the outer periphery of the sheet roll R. Then, in this state, the cutting blade 13 provided on the end treatment beam 9 operates to cut the narrow sheet S.

In this embodiment, as shown in FIG. 3 (A), the adhesive sheet piece T is placed from the front side of the narrow sheet S so as to cover the hole H formed in the terminal portion E of the narrow sheet S. The end of the sheet roll R is adhered by adhering the part of the adhesive sheet of the adhesive sheet piece T, which is seen through the hole H, to the surface of the lower narrow sheet S. Therefore, the hole H is opened immediately downstream of the cutting position at the same time when the narrow sheet S is cut. As the adhesive sheet piece T, an adhesive tape piece having an adhesive applied on one surface, a label having an adhesive applied on one surface, or the like is used.

As shown in FIG. 4, the end treatment beam 9, the cutting blade 13, the pressing member 10, the back support beam 12, and the pressing roller 11 extend over the entire width of the passage of all the narrow sheets S. Further, the punch 1 for making the hole H shown in FIG.
4 are arranged so as to correspond to each narrow sheet S. The terminal processing beam 9 is supported by a pair of swing arms 15, and the swing arms 15 can be tilted by swinging around a support shaft 16 by receiving the driving force of a fluid pressure cylinder (not shown). Come on. The pressing member 10 is the side plate 17 of the terminal treatment beam 9.
Both ends are attached to. The wide strip S0
Is divided into eight narrow sheets S in the embodiment shown in FIG.

As shown in FIG. 5, the cutting blade 13 of the end treatment beam 9 and the pressing member 10 allows the cutting edge to advance and retreat toward the surface of the narrow sheet S approaching the new winding core C. It can be pushed and pulled by a fluid pressure cylinder 19 attached to the end treatment beam 9 by being inserted in the slit 18 between them.

The punch 14 is a cutting blade 13 of the end treatment beam 9.
It is slidably inserted into a hole 20 provided on the downstream side immediately below, and the lower end of the punch 14 is engaged with an engaging piece 21 fixed to the cutting blade 13. Therefore, when the cutting blade 13 is pushed up by the fluid pressure cylinder 19, the punch 14 also rises. Further, since the punch 14 is urged downward by a spring (not shown), it automatically sinks into the hole 20 when the pushing force is lost. In order to easily deal with the change of the sheet division specifications, the holes 20 are provided in advance at positions corresponding to the individual narrow sheets S in various sheet division specifications, and holes necessary when the sheet division specifications are changed. It is better to replace the punch with 20.

A suction bar 22 for suction-holding the adhesive sheet piece T of each narrow sheet S is attached to the terminal treatment beam 9 by a cutting blade 13.
Immediately after the above, a groove 23 for holding along the path of each narrow sheet S is provided. When the suction bar 22 is received so that the adhesive sheet piece T does not stick to the narrow sheet S until the end of the narrow sheet S comes directly above the groove 23, the adhesive sheet held on the upper surface of the suction bar 22. The upper surface of the piece T is formed to a depth that does not protrude into the passage.

The suction bar 22 has a hollow inside,
A large number of small suction holes 22a are provided on the upper surface side by side in the longitudinal direction. Then, the air inside can be sucked out through the hose 24 by a vacuum pump, a ring blower or the like (not shown). Therefore,
The inside can be made a negative pressure, and the adhesive sheet piece T placed on the suction hole 22a can be sucked and held at various positions. Then, when the terminal treatment beam 9 is in the retracted position shown in FIG. 1, the suction bar 22 slides on the guide body 25 extending in the longitudinal direction of the terminal treatment beam 9 as shown in FIG. It can be taken out from the inside of the machine to the side of the machine through the opening 27 provided in the. This guide body 25 facilitates and ensures the attachment of the suction bar 22 to the groove 23 and the removal to the machine side. The chain line in FIG. 6 shows a state in which the suction bar 22 is received in the groove 23. The hose 24 is inserted in a groove 23a formed below the groove 23 so as not to interfere with the attachment and detachment of the suction bar 22, and is folded back in the middle.

The suction bar 22 placed in the groove 23 is composed of a fluid pressure cylinder 28 attached to the lower portion of the end treatment beam 9 and a groove-shaped push-up member 29 joined to its piston rod 28a as shown in FIG. It can be pushed up by the push-up mechanism 30.
The adhesive sheet piece T sucked and held on the upper surface can be attached to the surface of the narrow sheet S backed by the back receiving beam 12.

The back support beam 12 is attached to the tip of the piston rod of the fluid pressure cylinder 31 shown in FIG. There are a pair of fluid pressure cylinders 31 and they are supported by beams 32 fixed to the machine frame 26 and parallel to the winding shaft 3. The pressing force of the back receiving beam 12 against the end treatment beam 9 is adjusted so that the narrow sheet S sandwiched between the two can be pulled out.

Further, as shown in FIG. 2, the terminal treatment beam 9 is provided with a pull-out mechanism 33 for pulling out the downstream cutting end of the narrow sheet S from the cutting position by the cutting blade 13 to directly above the groove 23. It is provided. The pull-out mechanism 33 is the movable roller 3
4, the movable roller 34 is supported on the upper end of an arm 36 which can swing around a movable support shaft 35. Movable spindle 3
5 is pivotally attached to the tip of a movable rod 37 provided on the terminal treatment beam 9, and the movable rod 37 is guided in the longitudinal direction and can be pushed and pulled by a fluid pressure cylinder 38.

The pressing roller 11 is supported on the lower end of the arm 36, and the arm 36 can be pushed and pulled by a fluid pressure cylinder 39. This fluid pressure cylinder 39 is
One end of the cylinder body is pivotally attached to the side plate 17 of the terminal treatment beam 9, and the tip end portion of the piston rod is connected to the movable support shaft 35 of the arm 36.
It is installed pivotally below. As shown in FIG. 4, the arms 36 are provided on both sides of the movable roller 32 and the pressing roller 11.

Therefore, when the arm 36 is pushed by the fluid pressure cylinder 39, the arm 36 rotates around the movable support shaft 35 and tilts, and the pressing roller 11 can be pressed against the outer circumference of the sheet roll R. When the arm 36 is pushed by the pressure cylinder 38, the movable roller 34 moves away from the cutting blade 13 as shown by the chain line in FIG. 2, and the narrow sheets S are pulled out all at once by a certain length.

In order to carry out the terminal treatment by adhering the end of the cut narrow sheet S to the outer periphery of the sheet roll R, as shown in FIG. 6, the adhesive sheet piece T is previously taken out to the machine side by suction. It is applied on the bar 22 so as to correspond to each narrow sheet, and suction-held by the suction bar 22. At this time, the adhesive sheet piece T is oriented so that the non-adhesive surface contacts the suction bar 22. Then, the suction bar 22 is inserted into the groove 23 of the end treatment beam 9 before the sheet roll R is rolled up at the winding position I.

When the narrow sheet S is cut by the cutting blade 13 as shown in FIG. 5, the cutting blade 13 and the punch 14 are retracted into the terminal processing beam 9, and the end of the narrow sheet S is shown by a chain line. Are pulled out all at once by the pull-out mechanism 33, and the suction bar 22 is pushed up by the push-up mechanism 30 so that the prepared adhesive sheet piece T is adhered so as to close the hole from the front side of the narrow sheet S terminal. At this time, the suction bar 22 stops suction as necessary so that the adhesive sheet piece T can be easily separated from the suction bar 22. After that, while the sheet roll R is being held by the holding roller 11, the winding shaft 3 at the sheet roll unloading position II is rotationally driven to move the narrow sheet S around the sheet roll R.
The end portion of the adhesive sheet is wound up, whereby the remaining adhesive surface of the adhesive sheet piece T is adhered to the surface of the lower narrow sheet S.
In this way, when the end processing of the sheet roll R is completed, the end processing beam 9 and the back receiving beam 12 are retracted to the positions shown in FIG. Further, the suction bar 22 is pulled out to the machine side along the guide body 25, an adhesive sheet piece T for the next end treatment is attached to the suction bar 22, and it is returned to the groove 23 of the end treatment beam 9 again.

In this embodiment, all the punches 14 are detached from the end processing beam 9, and when the end of the narrow sheet S is pulled out by the pulling mechanism, the suction bar 22 is pulled out.
If the position where the adhesive sheet piece is applied to the suction bar 22 is moved to the side of the cutting blade 13 so that the adhesive sheet piece T held in FIG. Such a sheet roll R can be obtained.

Although one embodiment of the present invention has been described above, the embodiment can be variously changed as needed without changing the gist of the invention. For example, the pull-out mechanism may be a driven nip roller that rotates while sandwiching the narrow sheet S, instead of the one including the movable roller described above. In that case, one of the driven nip rollers is supported by the end treatment beam, and the other roller is supported by the backing beam. In short, the pull-out mechanism may be any mechanism that can pull out the end of the cut narrow sheet to a predetermined position.
Further, when only the sheet roll R subjected to the terminal treatment is obtained as shown in FIG. 3B, it is not necessary to provide a punch.
In addition, the winding roll at the sheet roll unloading position is set to
It is also possible to use a sheet which is rotated by a small angle in accordance with the radius to pick up the narrow sheet S. The adhesive sheet pieces may be applied to the suction bar manually or automatically using a labeler or the like.

[0033]

According to the present invention, the individual adhesive sheet pieces are adsorbed to the adsorption bar at positions corresponding to the respective sheet rolls on the winding shaft, and a part of the adhesive sheet pieces is adsorbed by the adsorption bar. Attach to the roll winding sheet terminals all at once,
Press the sticky adhesive sheet pieces onto the sheet rolls simultaneously with the pressing roller. Therefore, it is possible to efficiently obtain a sheet roll in which a part of the pressure-sensitive adhesive sheet piece is adhered to the surface of the winding sheet terminal portion, and the remaining portion of the pressure-sensitive adhesive sheet piece is adhered to the surface of the lower winding sheet. . Further, since the terminal can be surely processed, waste of sheets due to defective terminal processing is reduced. Further, since the adhesive sheet piece can be prepared even during winding, the stop time of the sheet dividing and winding device can be significantly shortened, and the operation rate can be improved.
Further, the suction bar is taken out to the machine side, and after the adhesive sheet piece is applied, it is returned to the holding means of the terminal treatment beam and is made to stand by, so that it is not necessary for an operator to enter the machine and prepare the adhesive sheet piece. Therefore, the labor of the worker is significantly reduced,
And secure. Further, since it is not necessary to provide a mechanism for applying the adhesive sheet piece of each narrow sheet to the suction bar between the rolled-up sheet roll and the new winding core at the winding position, the structure inside the machine Does not become complicated and the space occupied by the winding section does not increase.

When a punch for each narrow sheet is provided between the cutting blade and the groove of the terminal treatment beam, a hole is made at the end of the narrow sheet, and an adhesive sheet is adhered to the surface of this hole to form a hole. It is possible to efficiently obtain a sheet roll in which the pressure-sensitive adhesive sheet is adhered to the surface of the narrow sheet as the lower layer and subjected to terminal treatment.
