DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tab attaching apparatus for a reel-making apparatus for tailoring the starting end of a web on which the web has been wound in a roll form and then temporarily fixing the starting end of the web to the outer peripheral surface of the reel. About.

[0002]

2. Description of the Related Art In a rotary press or the like, when the reel on which a web is wound into a roll becomes small in diameter, that is, when the remaining web becomes small, the starting end of a new reel web is bonded to the web of the reel being fed. The web of the reel being fed is cut while being spliced, and the reel to be fed is switched so that the web can be continuously supplied. For this reason, for example, as shown in FIG. 8, a substantially V-shaped cutting process is performed on the start end side of the web 101 so that the newly fed reel can be bonded and bonded. Double-sided adhesive tape 10 on the cut edge
2, a tailoring operation for temporarily fixing the central portion of the starting end of the web 101 to the outer peripheral surface of the reel 100 with the tab 103 is performed in advance (for example, see Japanese Patent Publication No. 7-94296).

[0003] When bonding the reel 100 thus tailored, an operator peels off the release paper attached to the outer surface of the tab 103 or the like immediately before the bonding. Not only is the work efficiency of the adhesive splicing poor, but there is a risk that the peeling of the release paper may be forgotten. Therefore, for example, Japanese Patent Publication 5-24056
In the Japanese Patent Application Publication No. JP-A-2003-175, in bonding and joining the tailored reel, the suction member is pressed against the release paper on the outer surface side of the tab, and after the release paper is suctioned under reduced pressure by the suction member, the suction member is moved away from the reel. A peeling device has been proposed in which the release paper is peeled off from the tub and collected just before the bonding of the reel.

[0004]

However, in the above-described peeling apparatus, if the suction force of the suction member is slightly increased, the tab is peeled off from the reel with the peeling of the release paper. In addition, there is a risk that the bonding and joining may not be performed reliably, and the installation is performed only for peeling off the release paper.

[0005] For this reason, there is a need for a means that can easily release the release paper from the tab without peeling the tab from the reel without using an apparatus that only releases the release paper from the tab. It had been.

[0006]

0a, 20b, guide pin 21, auxiliary guide pin 22
In this embodiment, the tab feeding means is constituted by a and 22b.

On the other hand, as shown in FIGS. 1 and 2, below the inner surface of the base plate 11a of the casing 11, an actuator 23 with the tip of the rod 23a directed toward the tip of the casing 11 forms a pair. Installed. Pressing rollers 24 are rotatably attached to the distal ends of the rods 23a of these actuators 23, respectively. That is, by extending the rod 23a of the actuator 23, the pressing roller 24 can be pressed against the outer peripheral surface of the reel 100 set at a predetermined position, and by contracting the rod 23a of the actuator 23,
The pressing roller 24 can be separated from the outer peripheral surface of the reel 100 set at a predetermined position and stored in the casing 11. In the present embodiment, such an actuator 23, a pressing roller 24, and the like constitute a web pressing unit.

As shown in FIGS. 1 to 3, on a plane connecting the axis of the reel 100 set at a predetermined position and the axis of the actuator 12, that is, in the vicinity of the pressing roller 14, Is provided with a sensor 25 which is a detecting means for detecting the start end of the reel 100, and the actuator 12 operates based on a signal from the sensor 25.

The operation of the reel tailoring device provided with the tab attaching device thus constructed will be described below. A chuck 1b of a reel support arm 1a of the reel support device 1 supports the reel 100 transported by a carriage (not shown), and the reel support arm 1a rotates to set the reel 100 at a predetermined position. When 1b rotates,
As in the related art, the reel 100 rotates, and the starting end side of the web is fed out to the upper surface of a worktable (not shown), and the start end side of the web is suction-fixed by being sucked from a suction hole (not shown) formed in the worktable. A substantially V-shaped cut is formed at the start end of the web by a main processor (not shown), and a double-sided adhesive tape is attached thereto. After the start end of the web is removed along the cut, the reel 100 is rewound. Then, the starting end side of the web is wound up.

When the web whose tail end is thus started to be wound on the reel 100, the rod 23a of the actuator 23 extends, and the pressing roller 24 comes into contact with the outer peripheral surface of the reel 100, so that the end of the web at the start end is formed. While suppressing the flutter, the sensor 25 starts detecting the start of the web of the reel 100.

When the sensor 25 detects the start end of the web 101 (see FIG. 6A), the actuator 12 operates based on a signal from the sensor 25 to operate the pressing roller 14.
Is pressed against the outer peripheral surface of the reel 100. When the pressing roller 14 is pressed against the outer peripheral surface of the reel 100, the pressing roller 14 and the winding shafts 16 and 17 rotate with the rotation of the reel 100, and the tab 103 of the tab reel 105 is rotated.
Is fed to the leading end side of the pressing roller 14 and temporarily fixes the start end of the web 101 to the outer peripheral surface of the reel 100 (FIG. 6B).
reference).

After temporarily stopping the starting end of the web 101,
That is, when the reel 100 rotates by a predetermined angle after the sensor 25 detects the start end of the web 101, the actuator 12 is actuated and the pressing roller 14
And the rotation of the reel 100 stops,
The rod 23a of the actuator 23 contracts and the pressing roller 24 is stored in the casing 11.

That is, the starting end of the web 101 is
0, and then a tab 10 is attached to the beginning of the web 101.
While the tape 3 is directly attached to the tab reel 105, the starting end of the web 101 is temporarily fixed to the outer peripheral surface of the reel 101, and at the same time, the release papers 104a and 104b are peeled off from the tab 103 and collected.

For this reason, a device for peeling off the release paper 104a of the tab 103 at the time of bonding and joining the reels 100 becomes unnecessary, and the tab 1 is removed from the starting end of the web 101.
The release paper 104a can be easily peeled from the tab 103 without peeling the release paper 104.

Therefore, according to the tab sticking device of the reel tailoring device, it is possible to secure the installation place of the device when peeling the release paper 104a of the tab 103 and to solve the problem of the cost, and to eliminate the problem of the reel. 100
Can be securely bonded.

Further, since the pressing direction of the pressing roller 14 and the detection direction of the start end of the sensor 25 are set to directions substantially orthogonal to the axis of the reel 100, even if the diameter of the reel 100 is changed, the tab 103 can be stuck. Direction and web 101
The direction in which the start end of the tab is detected does not change, and variations in the tab sticking position can be suppressed.

In this embodiment, as shown in FIG. 6A, the central portion of the starting end of the web 101 of the reel 100 is detected by the sensor 25. If it is difficult to detect the above portion due to the relationship, for example, by detecting a predetermined portion of the edge portion of the web 101 along the double-sided adhesive tape 102 by the detection unit, the position of the center portion of the start end of the web 101 is determined You only have to figure out.

As a method of detecting the starting end of the web 101 by a sensor, a marker is attached to the center of the starting end of the web 101 during the tailoring work by the main processor, and a photoelectric sensor is applied. If this is the case, the starting end can be easily detected.

Further, in the present embodiment, as shown in FIG.
After the a, 104b and the tab 103 are guided by the guide pins 21 and the like, the release paper 104b is taken up by the take-up shaft 17, and the release paper 104a and the tab 103 are sent out to the tip end side of the pressing roller 14. The guide pin 21 and the auxiliary guide pins 22a and 22b are omitted, and the tab reel 1 supported on the feed shaft 15 as shown in FIG.
05, the release paper 104b is wound directly by the winding shaft 17, while the release paper 104a and the tab 103 are pressed by the pressing roller 14.
If it is sent directly to the front end side of the device, the number of parts can be reduced and the cost can be reduced. However, according to the embodiment as shown in FIG.
Can be peeled off from the tab 103,
Of the reel 1 can be kept to a minimum.
The temporary fixing of 00 can be performed more reliably.

[0030]

According to the tab sticking device of the reel tailoring device of the present invention, a device for peeling off the release paper of the tab at the time of bonding and joining the reels is not required, and the tab is pulled from the starting end of the web. Since the release paper can be easily peeled off from the tab without peeling off, it is possible to secure the installation place of the device when peeling off the release paper of the tab and to eliminate the disadvantages of cost, and to attach the reel. Splicing can be performed reliably.
