[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for sticking an adhesive tape for sticking a leading end portion of a paper wound on a paper tube which is a core of paper wound by a winder device, and more particularly to a width of the paper wound. The present invention relates to an adhesive tape sticking device for a paper take-up paper tube that can stick an adhesive tape in a smaller area.

[0002]

2. Description of the Related Art Paper manufactured by a paper machine is formed with a width substantially equal to the maximum paper width allowed by the paper machine. With this maximum width paper roll, it is not possible to directly supply it to a printing machine, etc., so it is necessary to re-form the paper roll with the necessary width according to each application, and this was reformed from the paper mill. The roll of paper will be shipped. Therefore, the paper roll manufactured by the paper machine is supplied to the winder device and rewound into a paper roll having a desired width.

In the winder device, a paper roll manufactured by a paper machine is set on the supply side, and an appropriate number of paper tubes having a length corresponding to the required width of the paper roll are arranged in the axial direction on the completion side. The rolled paper set on the supply side is cut into a desired width through a slitter knife or the like, and the cut paper is wound around the respective paper tubes. In order to reliably wind the cut paper on each paper tube, the leading end of the paper must be attached to the surface of the paper tube. Therefore, the adhesive tape is attached to the outer peripheral surface of the paper tube before winding the paper. In addition, this adhesive tape is a double-sided adhesive tape, and one-sided adhesive tape is folded in two at the center of its width, one side is adhered to the paper tube, and the other side is adhered to the tip of the paper. Sometimes you want to.

An adhesive tape sticking device is used to stick the adhesive tape to the surface of the paper tube. As this type of adhesive tape sticking device, there is, for example, a sticking method for sticking an adhesive tape to a core tube (paper tube) in a winding machine and its device, which are described in JP-A-4-129962. The schematic structure of this adhesive tape sticking apparatus is shown in FIG. A rail 3 is provided parallel to the axis of the paper tube 1 for guiding the travel of a device body 2 which constitutes the sticking device. The device body 2 is provided so as to be movable up and down, and an adhesive tape 4 is held on the device body 2. When the adhesive tape 4 is attached to the paper tube 1, the apparatus main body 2 is lowered to bring the taping roller 5 supported by the apparatus main body 2 into contact with the paper tube 1 so that the apparatus main body 2 is attached to the rail 3. The structure is such that the adhesive tape 4 is attached while running along. In addition, the traveling of the apparatus main body 2 is
For example, a known mechanism such as chain drive or belt drive as described in the tape applying device in the winder device according to Utility Model No. 2587168 is used.
Further, the paper tube 1 is supported by an arm (not shown) swingably provided between the position where the adhesive tape 4 is attached and the position where the paper is wound, and the paper tube 1 to which the adhesive tape 4 is attached is It can be moved to the winding position by swinging the arm.

[0005]

However, in the above-described conventional adhesive tape sticking device for the paper winding paper tube, the following problems may occur. As shown in FIG. 6, the adhesive tape 4 is attached over almost the entire area of an appropriate number of paper tubes 1 arranged in the axial direction. The ends of the adhesive tape 4 can be adjusted to arbitrary positions with respect to the paper tube at the start point and the end point of application, but the adhesive tape 4 is continuous at the portion where the paper tubes are adjacent to each other. 4 is in a state of being stuck to the end of the paper tube. Each paper roll 6 that has been completely rewound by the winder device (shown in FIG. 7)
Is rolled on the floor, discharged from the winder device, and divided into respective webs 6. At this time adhesive tape 4
Is cut by receiving a shearing force between the respective paper tubes 1, but the adhesive tape 4 is not cut between the paper rolls 6 due to the force applied during rolling, and sticks out to one of the paper rolls 6 side. Sometimes it was cut off. For this reason,
As shown in FIG. 7, the adhesive tape 4 protruding from the end of the paper tube 1 may be adhered to the side surface of the paper roll 6.

When the paper roll 6 having the adhesive tape 4 adhered to the side surface is subjected to a printing machine or the like, the adhesive tape 4 becomes a resistance,
Alternatively, the adhesiveness of the pressure-sensitive adhesive tape 4 may shift to the side surface of the paper roll 6, the rewinding of the paper roll 6 may not be smoothly performed, and paper breakage may occur to hinder the printing operation.

Therefore, according to the present invention, the end portion of the adhesive tape attached to the paper tube can be positioned at a portion located inside the width of the paper roll by a length inside from the end portion of the paper tube. It is an object of the present invention to provide an adhesive tape sticking device for a paper winding paper tube that prevents the end portion from adhering to the side surface of the paper winding.

[0008]

In order to achieve the above object, an adhesive tape sticking device for a paper winding paper tube according to the present invention is provided with guides arranged along a suitable number of paper tubes arranged in the axial direction. In an adhesive tape sticking device for a paper winding paper tube, which is guided by a rail and sticks an adhesive tape on the surface of the paper tube while the apparatus main body is running, an end of an adjacent paper tube which is a part of the guide rail. Separation means for moving the main body of the apparatus in a direction separating from the paper tube is provided at a position corresponding to each part, and when the main body of the apparatus passes through the position where the ends of the paper tube correspond to each other, the device is separated by the separation means. The main feature is that the main body is separated from the guide rail.

When the apparatus main body is guided by the guide rails and runs, the adhesive tape is attached to the surface of the paper tube. When the apparatus body travels at the positions corresponding to the ends of the paper tube, the apparatus body is separated from the guide rail. In order to ensure that the adhesive tape is applied evenly, the adhesive tape is in an appropriately tensioned state, and when the device body is separated from the guide rail, the tension acting on the adhesive tape is stronger than the strength of the adhesive tape. Also becomes larger, so the adhesive tape is cut. Further, after the device main body has passed through the positions corresponding to the ends of the paper tube, the cutting portion comes into contact with the paper tube, so that the attachment of the adhesive tape to the paper tube is restarted. Therefore, the adhesive tape is not attached at the portion where the apparatus body passes through the positions corresponding to the ends of the paper tube, that is, the adhesive tape is not attached at the end of the paper tube.

The separating means may have a structure in which the main body of the apparatus can be raised and lowered, and when the main body of the apparatus reaches an appropriate position, the main body of the apparatus is lifted and separated from the guide rail.

Further, in the adhesive tape sticking device for the paper winding paper tube according to the invention of claim 2, the separating means is a separating guide portion provided on the guide rail so as to bulge from the guide rail. I am trying.

When the apparatus body travels on the separation guide portion, the apparatus body is separated from the guide rail by being guided by the separation guide portion bulging from the guide rail. For this reason, the tension of the adhesive tape increases and the adhesive tape is cut. After passing the separation guide part,
Since the main body of the apparatus is guided by the guide rail, the cut end of the adhesive tape comes into contact with the paper tube, and the adhesion to the paper tube is restarted.

In order to guide the apparatus body that has passed through the separation guide section to the guide rail again, the apparatus body can be lowered to the guide rail along the separation guide section by its own weight. It is preferable to urge the device body to move in the direction guided by the guide rail by the biasing means, because the device body can be surely guided to the guide rail.

Further, the adhesive tape sticking device for the paper winding paper tube according to the invention of claim 3 is characterized in that the separation guide portion is detachably attached to the guide rail.

Since the width of the paper roll varies depending on the application,
The winder device changes the attachment position of the slitter knife to change the cutting point of the paper roll so that it can be used for various uses of the paper roll. Therefore, the length of the paper tube is also changed according to the width of the paper roll, and the positions of the ends of the paper tube are changed. If the separation guide portion is detachable, this change can be dealt with. Then, the separation guide portion may be attached to the guide rail according to the length of the paper tube.

In the adhesive tape sticking device for a paper winding paper tube according to a fourth aspect of the present invention, a holder hole is formed on the surface of the guide rail, and a support leg portion that can be inserted into and removed from the holder hole is formed in the separation guide portion. Is provided, and the separation guide portion is detachably attached to the guide rail.

When the support leg portion is inserted into the holder hole, the separation guide portion is mounted on the guide rail. If this holder hole is formed at each position according to the length of the paper tube, even if the width of the paper roll formed by the winder device is changed, the holder hole for inserting the support leg portion of the separation guide portion is inserted. It is possible to easily deal with the paper tube corresponding to the paper roll by simply changing
