Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper web gluing device that adhesively polymerizes the ends of a paper web so that the gluing device itself performs a wrapping function.

Conventionally, the paper that has already been wound into a roll has been wrapped in separately prepared wrapping paper, wrapping vinyl, or the like. However, this method not only requires wrapping paper or wrapping vinyl, but also the wrapping work of heavy paper rolls is complicated and troublesome, requiring additional labor and time, and not only increases costs. Plastic packaging has disadvantages such as there is no way to reuse it and it cannot be disposed of by incineration. The present invention has solved the above-mentioned drawbacks, and its object is to provide a gluing device for obtaining a web without the need for preparing the above-mentioned wrapping paper or wrapping vinyl.

Hereinafter, typical embodiments of the present invention will be described according to the illustrations.

FIG. 1 is a side view of a web produced by the web gluing apparatus according to the present invention, in which the end of the web 1 is approximately 1.
Glue is applied to the back side of the paper over a length of about 8 (5 to 6 sheets), and in this state it is wound up into a roll, each layer of paper 2 is adhesively polymerized by the glue, and the outer shell of the rolled paper 1 is wrapped. A covering layer 3 is formed in place of paper.

This covering layer 3 has strength and functions satisfactorily as a wrapping paper because the paper 2 is layered and each layer is pasted. 2 to 4 are side views of a gluing device for paper rolls according to the present invention, and the gluing device A includes a winding roll 4,
It consists of a tension roll 5, a plate roll 6, a doctor roll 7 with a roughened circumferential surface, a calling roll 8, and a glue tank 9, and the rolls 4 to 8 are installed in parallel at appropriate intervals. The paper 2 is pressed between the tension roll 5 and the plate roll 6 by the tension roll 5, and is wound up onto the take-up roll 4 under tension. The tension roll 5 is rotatably installed in the outer frame, and the above-mentioned plate roll 6, doctor roll 7 and calling roll 8
are supported by the frame 11 with their respective shafts rotatable by known means, and gears are located inside the supporting portions of these shafts with the frame 11 to connect their rotating shafts to the respective roll shafts. It is installed in accordance with the

That is, the plate roll 6 is provided with a pair of gears 12, the pick-up roll 8 is provided with two pairs of gears 13 and 14, and the doctor roll 7 is provided with a pair of gears 15, and the gear 12 meshes with the gear 13. The gear 14 fixed on the same axis as the gear 15
The rotation of one roll is sequentially transmitted to the rotation of the next roll by the meshing of these gears. Further, the plurality of constituent pieces 11a of the frame body 11 are pivotally connected so that the frame body 11 is swingable only in the front-back direction.
A stand 16 fixed to the lower part of the frame 11 is also supported and connected so as to be swingable only in the front and rear directions.

Pressing and pulling means such as a hydraulic or air cylinder 17 and a piston 18 are provided at the rear of the frame 11 to press and pull the rear part of the frame 11 and swing it back and forth. It is attached so that its height can be adjusted by sliding it.

That is, the height of the frame 11 is adjusted by a link mechanism. Further, a glue tank 9 is provided below the calling roll 8, and the lower circumferential surface of the calling roll 8 is submerged in this tank 9.

Glue tank 9 is fixed on rack 19, and rack 1
9 meshes with a pinion gear 20', the pinion gear 20 is fixed coaxially with a worm wheel 21, and the worm wheel 21 is connected to a handle 23 through meshing with a worm 22.

Next, a method for winding a paper roll using this apparatus will be explained.

First, hydraulic pressure or air is supplied into the cylinder 17 by known means to move the piston 18 backward as shown in FIG. Thereafter, the winding roll 4 is rotated by driving the power source, and winding of the paper 2 is started.

Immediately before winding up a predetermined amount of paper 2 is finished, for example, after reducing the winding speed to 300 mm or less, hydraulic pressure or air is supplied into the cylinder 17 from a supply port different from the above. Then, as shown in FIG. 4, the piston 18 is advanced to slide the frame 11 forward and return it to the vertical state. As a result, the plate roll 6, doctor roll 7, and calling roll 8 supported by the frame 11 are set directly at a high level, and the upper end of the plate roll 6 is placed on the back side of the paper 2 flowing above. Make contact from below. The plate roll 6 rotates due to its contact with the paper 2, and this rotation is transmitted to the calling roll 8 by the gears 12 and 13, and the lower part of the circumferential surface of the calling roll 8 is immersed in the glue tank 9. Therefore, the size liquid is deposited on the entire circumferential surface according to the rotation, and this size liquid is delivered to the surface of the plate roll 6 via the circumferential surface of the rolls 8, 7 by the transmission of the rotation of the rolls 8, 7. attached. And this version roll 6
The size liquid delivered to the peripheral surface is applied to the back surface of the paper 2 by the plate roll 6 which rotates while coming into contact with the paper 2 as it flows.
For example, the amount of application is about 2 to 6 days per day, and the amount is about 18 times.

The amount of paste applied can also be adjusted freely by replacing the meshed plate roll 6. and,
Operate the cylinder 17 again to remove the frame 11 as shown in FIG.
is set to a low position, the paper 2 is fed out one or two revolutions of the take-up roll 4, and the feeder is stopped.

Thereafter, the paper 2 to which this size liquid has been applied is wound around the outermost layer of the paper 2, which has already been wound up by a predetermined amount by the winding roll 4, in several layers, for example, about 5 to 6 sheets. With the passage of time, the size liquid hardens to form a covering layer 3 of the paper 2 over the outermost shell layer of the paper 2, thereby serving as a wrapping paper. In addition, the above-mentioned calling roll 8 transmits its rotation to the doctor roll 7 attached by contacting the circumferential surface of the roll 8 through gears 14 and 15, and since the circumferential surface of this doctor roll 7 is formed to have a lees surface. As the roll 8 rotates, the circumferential surface of the roll 8 is rubbed to scrape off the excess liquid adhering to the circumferential surface of the roll 8, and an appropriate amount of glue is delivered to the plate roll 6, and the paper 2 is coated in good condition. Glue is applied. In addition, the size liquid in the glue tank 9 decreases with the passage of time, but in this case, if the handle 23 is rotated and the glue tank 9 is raised by the rack 19, it will always be below the above-mentioned calling roll 8. The part can be maintained submerged in this tank 9.

It should be noted that the present invention is not limited to the above, and it goes without saying that various changes can be made within the scope of the invention.

As described above, according to the present invention, a part of the paper to be rolled up performs the wrapping function by itself, so that the entire winding work can be completed without preparing a separate wrapping paper or the like. It is extremely practical.

Further, according to the present invention, since the work of forming the coating layer on the outermost skin of the web can be performed continuously and in the same device as the paper winding work, time can be saved, and furthermore, Since the adhesion of the adhesive can be achieved with an extremely simple structure, there is no risk of inconvenience in implementation.
