Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is an automatic paper-rolling tailoring device for performing automatic tailoring for paper that is pulled out from the paper and whose tension is controlled.
The present invention relates to a tab separator peeling device.

(Prior Art) An example of a conventional automatic paper roll tailoring device is shown in FIGS. A support arm 2 is rotatably supported on a frame 1 of the automatic paper-roll tailoring device, and a paper roll is mounted on the support arm 2. After the defective skin is removed by the skin cutting device 3, the wound paper is wound by the discharged paper winding device 4. The skin following the defective skin is fed out by the conveyor belt 5, and the scratch detection sensor checks for scratches. When a good quality paper portion is reached, a negative pressure suction device on the table 7 operates, and this negative pressure causes the table 7 to move. Paper is set on top. The tip of the set paper is V
The tape is cut into a V shape, and the double-sided adhesive tape is applied by the tape applying device 9 along the edge of the V shape. Further, a tip tape is attached to the front surface of the V-shaped tip portion, and a T tab is attached to the back surface by the tip tape and T tab attaching device 10. The tip tape is cut from a roll-shaped tape into a certain shape (arrow vane shape), then carried to a sticking position by a suction device, and stuck to the surface of the V-shaped tip portion by a sticking device 10 as shown in FIG. Affixed to.

Further, the T-tabs, which are formed into a certain shape (T-shape), are put in the tab stacker 11, taken out from the tab stacker one by one by a suction means (not shown), transported to the same place as the above-mentioned tip tape, and a sticking device. At 10 it is glued to the back of the V-shaped tip. At this time, the V-shaped tip is lifted up by the suction device (not shown) so as to be lifted up (FIG. 7),
The T tab sucked by the suction means is pressed and adhered to the back side of the V-shaped tip, the separator is peeled off by the suction means while rewinding the V-shaped tip, and the T tab is attached to the paper roll. Alternatively, the V-shaped tip of the paper roll on the table is lifted by the suction device, and the T tab is inserted between the back surface of the lifted front end and the table by the suction means, and the claw and suction pad provided on the table. Use to remove the separator and rewind the paper roll to attach the T tab.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional apparatus, since the skin of the paper roll is pulled out onto the table and the skin is fixed on the table to form the V-shaped tip, the machine length becomes long and space is saved. Costly. In addition, a tape sticking device and a triangular tip cutting device required for tailoring were required.

Furthermore, the forming of the tip tape, the transfer by suction to the sticking position, and the sticking of the tip tape by this suction device can be performed by the same method as the automatic tailor for the roll of paper using the table. As described above, there is a problem that the T-tab separator removing means cannot be used.

In view of the above, the present invention constitutes an automatic paper-roll tailoring device having a short machine length by eliminating the table in order to solve the above problems, and integrates the tape sticking device and the triangulation tip device into a whole device. It is intended to provide a T-tab separator peeling device for an automatic paper roll tailor for the purpose of simplifying the above.

(Means for Solving the Problem) Therefore, according to the present invention, after the defective paper in the skin layer of the paper roll is cut and removed, both sides are cut along the edges of the V-shaped skin cut from both sides of the paper roll toward the center. An adhesive tape and a T-tab separator stripping device of an automatic web-taping device that attaches a tip tape and a T-tab to the tip of this V-shape, wherein the T-tab separator stripping device includes a suction device for sucking and holding the tip tape and a T-tab separator. T that allows the T tab separator to be bent toward the tip tape side when attracted
A tab separator suction device is provided, which serves as means for solving the problem.

(Operation) The tip tape suction device of the T tab separator stripping device sucks the tip tape side, and the T tab separator suction device sucks the lower part of the T tab separator, and in this state, the suction pad of the T tab separator suction device is 90 °. Rotate and bend the T-tab separator into an L-shape. Since the separator is bent into an L shape, the separator peels off more easily than the T tab. Next, when the T-tab separator suction device is rotated 90 ° contrary to the above, the separator is peeled off from the T-tab, and the adhesive surface portion on the back surface of the T-tab curls outward with respect to the outer peripheral surface of the web. For this reason, when the paper roll is rewound, the T tab is attached in a good state without wrinkles on the outer peripheral surface of the paper roll.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. FIGS. 1A and 1B show a T-tab separator peeling device according to an embodiment of the present invention. In the figure, the T-tab separator peeling device 21 includes a tip tape suction device 22, a T-tab separator suction device 23, a rotary actuator 24 for rotating the suction device 23 90 °, a cutter cylinder 25, and a pin 28 around the pin 28 by the cutter cylinder 25. A cutter 26 attached to a cutter holder 27 that swings the cutter, a cam groove 27b for moving the cutter 26 in a predetermined length in a substantially straight line for trimming the front end of the tape, a pin 27a fitted to this, and a front and rear It is composed of a moving cylinder 29. The cylinder 29 is a rodless cylinder.

By the way, as shown in FIGS. 2 and 3, the front end tape and the T tab are adhered to the front surface of the front end portion of the paper roll and the T tab to the rear surface thereof. The front end portion of the paper roll is cut and overlapped with the paper (the front end tape is cut and aligned), and then the T-tab separator is peeled off. The T-tab separator stripping device 21 cuts the tip of the tip tape and cuts off the separator.

Hereinafter, the procedure of overlapping and cutting the tip portion and removing the T tab separator by the T tab separator removing device 21 will be described. First, the tip overlap cutting is performed in the next step. That is, the T cylinder is moved to the position where the web is fed by the forward / backward traveling cylinder 29.
The tab separator stripping device 21 is moved forward, and the suction device 22 sucks the surface of the front end tape, and the suction device 23 sucks and holds the lower position of the paper roll. Next, when the cutter cylinder 25 is advanced, the cutter holder 27 swings around the pin 28 as a fulcrum to perform the cutting operation. Specifically, at this time, the guide pin 27a attached to the lower surface of the cutter holder 27 is guided by the guide cam groove 27b of the cutter holder 27 and moves in the guide cam groove.
By the movement of the cutter holder 27 at this time, the tip of the cutter 26 moves in parallel to the suction surface (lower side) of the suction device 22, and the tip of the tip tape is cut substantially straight into a predetermined length. After cutting, each cylinder 25 and 29 retreat once, the cutter 26 and the suction device.
22 returns to the initial position.

Next, after the T tab is attached in another step, the paper roll is fed again for peeling the separator. In this state, the forward / backward moving cylinder 29 advances again, and the suction device 22 sucks the tip tape (FIG. 4 (a)). Next, the rotary actuator 24 turns, which causes the suction device 23 to move upward. At this time, the tongue-shaped portion (paste portion) of the T-tab is caught by the tip of the suction device 23 and is sandwiched between the lower surface of the suction device 22 and the pad of the suction device 23 to suck the separator (FIG. 4). (B)). Next, when the suction device 23 is moved to the lower position by rotating the actuator 24 in the opposite direction to 90 °, the separator is separated from the T-tab (FIG. 4 (c)). At this time, the tongue of the T-tab bends to the outside of the outer peripheral surface of the web as shown in FIG. 4 (c). As a result, the adhesive surface does not come into contact with the other members at the time of winding, and when the winding is completed, the T tab is bonded to the outer peripheral surface in a good state without wrinkling.

(Effects of the Invention) As described above, according to the present invention, the suction device and the cutter cylinder are moved by the forward-backward movement cylinder, and after the suction tape is sucked and fixed by the suction device, the cutter cylinder is operated. It is possible to cut the tip in alignment, and the cut tip is cut in a substantially straight line by the guide groove cam. Further, since the contact position of a part of the blade of the cutter (for example, the cutting edge with the best sharpness vibrating by ultrasonic waves) and the object to be cut is constant, the tip tape can be cut accurately. Also, by providing a T-tab separator suction device that works in conjunction with the forward / backward movement cylinder and that is rotated by a rotary actuator, not only can the T-tab separator be automatically peeled off, but the glue part of the tongue-shaped part of the T-tab can be removed. Since it can be deflected in a direction away from the outer peripheral surface of the paper roll, when the winding of the paper roll is completed, the T tab can be normally adhered without wrinkles on the T tab, and the occurrence of paper splice failure can be prevented.
