Abstract

PURPOSE:To rapidly adhere the double-coated adhesive tape to the sheet to be fed by providing a touch roll whose surface is made of a material whose adhesiveness is worse than that of the sheet, and a tape-adhering unit which adheres the double-coated adhesive tape in the axial direction of the outer circumferential surface. CONSTITUTION:A touch roll 8 is retracted from a drum 3 while a paper 19 is wound up to a winding paper roll 2. When the winding operation of the paper 19 is close to completion, a tape adhering unit 9 travels in the axial direction of the outer circumference of the touch roll 8, and adheres the double- coated adhesive tapes B, E. Then, the touch roll 8 is brought into contact with the drum 3, and rotated by being driven. This allows the double-coated adhesive tapes B, E to be adhered to the surface of the paper on the outer circumferential surface of the drum 3. The double-sided adhesive tapes B, E are moved to the paper 19 because the surface of the touch roll 8 is made of a material such as rubber and synthetic resin whose adhesiveness is worse than that of the paper. Subsequent operations are included in the operation of a tail seal device of the winding paper roll.

Since the present invention should be understood in these entire systems, the apparatus for applying the double-sided adhesive tape to the paper or the like of the present invention will be described including the entire system.

FIG. 1 shows a device for applying a double-sided adhesive tape to paper or the like according to the present invention together with a tail seal device for a roll of roll of paper. ) Is to seal the tail.

The take-up paper roll (2) is a roll of paper (19) which is placed on a pair of drums (3) and (4) and rotated by being held by a rider roll (7). is there. A touch roll (8) is provided on the drum (3) so as to be able to come into contact with and retract from the drum (3).

The touch roll (8) constitutes a part of a device for attaching the double-sided adhesive tape to paper or the like. The double-sided adhesive tape (10) can be attached to the touch roll (8) in the axial direction of the outer peripheral surface thereof by the tape application unit (9). That is, the touch roll (8) is retracted from the drum (3) while the paper (19) is being wound around the roll (2).

When the winding of the paper (19) approaches the completion, the tape applying unit (9) runs in the axial direction of the outer peripheral surface of the touch roll (8) and applies the double-sided adhesive tapes B and E. On the other hand, a cutter (6) is provided apart from the outer periphery of the drum (3) so as to be able to cut the paper (19) in the axial direction of the drum (3).

The cutter (6) and the push roll (11) outside the cutter (6) are attached to the arm (5) and the drum (3).
It is provided so as to be able to come into contact with and retract from the paper roll (2) at a position separated from the outer circumference of the roll. Next, the take-out path (16) is closely provided on the outer circumference of the other drum (4).

An opening / closing plate (1) in the middle of the take-out path (16)
A core holder (13) attached to the arm (12) is housed below the armature (5). Then roll paper roll (2)
As described above, as shown in FIG. 1, the tapes B and E are attached in the axial direction of the outer peripheral surface of the touch roll (8) when the winding is almost completed.

Next, the touch roll (8) is brought into contact with the drum (3) as shown in FIG. 2 and rotated by being driven. As a result, the double-sided adhesive tapes B and E are attached to the surface of the paper (19) on the outer peripheral surface of the drum (3).

The double-sided adhesive tapes B and E are transferred to the paper (19) because the surface of the touch roll (8) is made of a material such as rubber or synthetic resin having a poorer adhesiveness than the paper. This completes the operation of the device for applying the double-sided adhesive tape to paper or the like.

From this point onward, the operation of the tail seal device for the paper roll will be the main focus. That is, the double-sided adhesive tapes B and E travel along with the paper (19) and the drum (3), and come close to the contact point between the drum (3) and the paper roll (2).

Before reaching the contact, the arm (5) advances to the web roll (2) as shown in FIG. 3 and push roll (1).
1) contacts the web roll (2) and pushes it towards the drum (4). As can be seen in FIG. 3, the web roll (2) will be separated from the drum (3).

The cutter (6) is actuated at this separated portion to cut the paper (19) immediately after the double-sided adhesive tape B or at the rear portion thereof. At the same time, the paper presser (18) is the drum (3)
Against this, hold the paper (19) and prevent it from sliding down.

The paper roll (2) is further provided with an arm (5).
The double-sided adhesive tape B passes through the pressing roll (11) while being pressed by the pressing roll (11). As a result, the tail of the paper roll (2) is sealed with the double-sided adhesive tape B.

The sealed paper roll (2) rolls over the take-out path (16) over the drum (4). This completes the operation of the tail seal device for the paper roll.

From here onward, the operation of the device for adhering the paper edge to the core will be the center. That is, when the paper roll (2) rolls from the position shown in FIG. 3 to the position shown in FIG. 4, the opening / closing plate (15) provided in the take-out path (16) is opened.

Next, the core retainer (1
3) will be lifted to feed a new empty core (14) between the drum (3) and the drum (4). That is, the new core (14) is held in advance in the core holder (13) and is used between the drum (3) and the drum (4).

A new core (14) is put in, and the drum (3) is reversed as required to put the double-sided adhesive tape E on the core (1).
Paste on 4). As a result, the paper (15) is prevented from slipping down, and at the same time, the paper retainer (18) shown in FIG. 3 retracts.

Next, the arm (12) and the core retainer (1
3) returns to the inside of the opening / closing plate (15) leaving the core (14), and the opening / closing plate (15) is closed as shown in FIG. On the other hand, the rider roll (7) descends again to sandwich the core (14) between the rider roll (7) and the drums (3) and (4), and at the same time, the drum (3).
(4) and the rider roll (7) rotate.

As a result, the paper (19) is wound around the core (14) by the double-sided adhesive tape E. This completes the operation of the paper edge adhering device to the core.

Next, in addition to the configuration shown in the above embodiment, the following modifications are possible. First, in the paper retainer (18) of FIG. 3, instead of this, a large number of holes are provided on the outer peripheral surface of the drum (3) to make the inside of the drum (3) a negative pressure so that the paper (19) is attracted to the drum (3). The paper (19) may be prevented from slipping off.

On the other hand, as shown in FIG. 4, when the paper edge (20) exists longer than the double-sided adhesive tape E, the paper edge (2
0) is doubled as shown in FIG. 5, resulting in a step difference at the beginning of winding. If the paper (19) is thin, this step may be left as it is, but if not, it is preferable to eliminate it.

As this method, for example, double-sided adhesive tape E
May be attached in proximity to the rear end of the front double-sided adhesive tape B.

In this case, the drum (3) may be reversed and the double-sided adhesive tape E may be attached to the core (14).

Next, two rows of double-sided adhesive tapes B and E were attached to the paper (19), but the rear double-sided adhesive tape E was not supplied from the touch roll (8) and was previously attached to the new core (14). You may keep it.
