Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for an automatic paper splicing pretreatment device for a paper roll for pre-bonding a paper roll for printing. The present invention relates to a tab sticking device capable of sticking a plurality of tabs at predetermined intervals.

[0002]

2. Description of the Related Art Generally, a printing paper roll (for example, a commercial printing paper roll) brought into a printing factory is preliminarily spliced so that the winding paper web can be automatically spliced in a paper feeding section of a rotary press. Pre-processed. In this paper splicing pretreatment, as shown in FIG. 12, the front end of the paper roll P is cut into a substantially trapezoidal shape, and a double-sided adhesive tape is attached to the surface of the front end to form a paper splicing adhesive layer a. The tip portion is attached to the outer surface of the paper roll P by a plurality of tabs T.

Thus, in the rotary press for printing, as shown in FIG.
As shown in, a new paper roll P that has been pretreated for paper splicing
Is mounted on the web supporting device 30, and is rotated at a constant circumferential speed with the web P'in use, which is fed to the rotary press 31 at a constant speed, and the end portion of the web P'in use is replaced with a new web P '. When pressed to the start end, the end portion of the paper P'in use and the start end of the new paper P'are joined together to form the adhesive layer a for paper splicing.
With this, the tab T is cut off and the starting end portion of the new paper roll P is continuously supplied to the rotary press. In FIG. 13, 30a is an arm of the paper roll support device 30, and 30b is a rotation shaft of the arm 30a.

On the other hand, in recent years, most of the pretreatments for paper splicing of the printing paper P for printing have been automated in order to reduce labor costs and improve work efficiency. For example, a tape sticking device or a tab sticking device. An automatic paper splicing pretreatment device having the above is used to form a paper splicing adhesive layer a on the front end portion of the paper roll P and to attach the tab T.

As a conventional tab pasting device used in an automatic paper splicing pretreatment device, for example, Japanese Patent Laid-Open No. 5-186 is known.
There is a known structure disclosed in Japanese Patent No. 111,
This is one in which a plurality of tabs T can be automatically attached to the leading end of the paper roll P cut in the width direction. That is, as shown in FIGS. 14 and 15, the tab attaching device has a long tab support mount wound in a roll shape on a traveling base 32 that can travel in the width direction of the web P and can be positioned, and this. A tab roll 33 that is detachably attached to the tab roll, a tab roll reel 34 that rotatably supports the tab roll 33, a take-up reel 35 that winds up the tab support mount, and a tab surface on the tab support mount. There are tab suction / pasting heads 36 that can move in the front-rear and left-right directions, respectively, and when the leading end of the web P fed out on the backup table 37 is cut in the width direction, the traveling platform 32 is attached to the front end of the web P. While moving intermittently along the tab roll 33, the tab roll 33 moves from the tab roll reel 34 to the take-up reel 35.
When the traveling platform 32 is stopped, the tab is adsorbed.
The sticking head 36 moves forward and backward to peel the tabs from the tab support mount of the tab roll 33, suck and hold the tabs, and then the tab suction / sticking head 36 traverses and moves forward to stick the sucked and held tabs to the leading end of the paper roll P. Is configured to.
In FIG. 14 and FIG. 15, 38 is the device frame,
39 is a support device for the paper roll P, 40 is a winding drive motor,
Reference numeral 41 is a tab suction / pasting head cylinder, 42 is a traveling table motor, 43 is a screw shaft, and 44 is a guide rail.

[0006]

By the way, in the tab attaching device, the traveling table 32 is intermittently moved in the width direction of the web P, and when the traveling table 32 is stopped, the tab suction / pasting head 3 is used.
The tab is peeled off from the tab support mount of the tab roll 33 by 6 and sucked and held, and the tab suction / pasting head 36
By this, the paper P is attached to the front end.
That is, since the tabs are attached to the front end portion of the paper roll P one by one along the width direction, it takes a considerable time to attach the tabs, and it is difficult to improve the work efficiency. There was a problem to say. Further, since the tab attaching device uses the tab roll 33 composed of a long tab support mount wound in a roll shape and a tab detachably attached thereto,
There is also a problem in that it is necessary to separately form a dedicated tab roll 33 having a relatively complicated structure, which causes a rise in processing cost.

The present invention was devised to solve the above problems, and its purpose is to enable a plurality of tabs to be efficiently attached to the leading end of a paper roll and to reduce the processing cost. The present invention provides a tab attaching device.

[0008]

In order to achieve the above-mentioned object, the tab attaching device of the present invention is arranged above the table at predetermined intervals in the width direction of the web and moves up and down with respect to the table. In addition, a plurality of traveling bases that can move back and forth, a drive mechanism that moves the traveling bases up and down and moves back and forth, a reel-shaped tab tape that is rotatably supported by each traveling base, and has an adhesive layer on one side, A pressing roller that is rotatably supported on the traveling table, is capable of contacting the table, and presses and sticks the tab tape that has been fed to the outer peripheral surface to the front end surface of the paper roll, and the pressing roller provided on each traveling table. A tape holding mechanism that holds the tab tape that has been fed to the outer peripheral surface on the pressing roller, and the tab tape that is attached to the leading end of the paper roll and is cut to a specified length Cutter mechanism that forms the It provided the platform, which is constituted from a cut forming cutter mechanism for forming a cut for cutting the stuck-tub in the front end portion of the web.

[0009]

When the rolled paper fed on the table is cut in the width direction and the adhesive layer for the paper splicing is formed at the leading end, the traveling bases of the tab attaching device simultaneously descend to push the pressing roller to the leading end of the rolled paper. Abut the part surface. At this time, since the tab tape is wound around the outer peripheral surface of the pressing roller and is held on the pressing roller by the tape holding mechanism, the front end of the tab tape is attached to the front surface of the winding paper. Will be worn. When the tip portion of the tab tape is attached to the surface of the tip portion of the paper roll, the holding state of the tab tape by the tape holding mechanism is released, and the traveling bases simultaneously move in the feeding direction of the paper roll. As a result, the tab tapes are sequentially fed out from the tape reel and attached to the leading end of the paper roll by the pressing roller. When a certain length of tab tape is attached to the tip of the paper roll,
The movement of each traveling platform is stopped, and the tab tape is held on the pressing roller by the tape holding mechanism, and in this state, each traveling platform rises to lift the pressing roller. At this time, the paper pressing mechanism prevents the leading end of the paper roll from floating. When the pressure roller is lifted, the cutter mechanism is activated to cut the tab tape. by this,
A tab with a certain length is formed from the tab tape,
The tab is attached to the front end of the web. still,
When the tab tape is cut, the front end of the paper roll is pressed to the table side by the paper pressing mechanism, so that the tab tape can be cut satisfactorily and smoothly. When the tab is attached to the front end portion of the paper roll, the notch forming cutter mechanism operates to form the notch for cutting on the tab.

In the tab attaching device of the present invention, traveling bases that can be moved up and down and moved back and forth are arranged in parallel in the width direction of the paper roll, and reel-shaped tab tapes, pressing rollers, tape holding mechanisms, and cutters are provided on the respective traveling bases. A mechanism, a notch forming cutter mechanism, etc. are provided respectively, and each traveling platform is simultaneously moved up and down and moved back and forth so that a plurality of tabs are simultaneously attached to the leading end of the paper roll. As a result, even when a plurality of tabs are attached to the front end portion of the paper roll, the tabs can be attached very quickly, and the work efficiency of the pretreatment for paper splicing can be significantly improved. Further, since the tabs are formed from the reel-shaped tab tape having the adhesive layer on one side, it is not necessary to separately prepare a dedicated tab roll having a relatively complicated structure, and the processing cost can be reduced. It can be planned.
