ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic thin paper winding device.
More specifically, it relates to an automatic thin paper winding device that blows air backwards from the suction section of the rear drum when the thin paper is wound around the core so that the adhesive applied to the core does not protrude from the leading edge of the thin paper. .

ようにしている。 When handling cardboard, which itself has sufficient rigidity, with an automatic winder, it is wound in the order shown in FIGS. 1A to 1E. That is, when the winding roll 1 reaches the required diameter and winding is completed, the rotation of the rear drum 2 and front drum 3 is stopped, and then the rider roll 4 is raised as shown in B, and the adhesive is applied upward from the nozzle gun 5. Glue is applied to the winding roll 1 by squirting it out. Next, the drum 2 is slightly rotated to adhere the paper 7 to the glued surface 6 of the winding roll 1, and then the winding roll 1 is displaced as shown in C, and the suction of the rear drum 2 is activated, and the cutter 8 cuts the paper. Cut across the entire width. The cut roll 1 is moved to another place, and a new core 9 is placed between the rear drum 2 and the front drum 3 as shown in D.
Next, the rear drum 2 is slightly reversed from state D to set the end of the paper at a position where it can be wound around the core 9, and the length at the beginning of winding is adjusted. Next, while the rider roll 4 is being lowered, adhesive is jetted upward from the nozzle gun 5 as shown in E to apply glue along the longitudinal direction of the core 9, and the rear drum 2
Then, the front drum 3 is rotated in the winding direction (forward rotation) to wind the core 9. When winding is completed (state A), steps B and C are repeated in the order.

１２からの折れ曲りが甚だしくなる。 However, when handling thin paper with insufficient rigidity using an automatic winder, as shown in FIG. , the thin paper may bend from the adhesive area and the glue may ooze out from the adhesive area. That is, when the core 9 is rotated in the winding direction after the adhesive is applied to the core 9, the tip 11 of the thin paper 10 is bent from the adhesive part 12 as shown in FIG. 3, and as shown in FIG. If the paper 10 is bent without covering the adhesive 13 on the surface of the core 9, the adhesive 13 will be exposed on the surface of the core 9. The thinner the thin paper 10 is, the more severe the bending from the bonded portion 12 becomes when the core 9 is rotated (normally rotated) after being bonded to the core 9.

Adhesive 1 that came out when trying to hold 1
3 adheres to the surface of the rider roll 4,
This will stain the surface of the rider roll 4 and cause noise to be generated during rotation.

得る。 As described above, according to the apparatus of the present invention, when the thin paper is cut after winding is completed, the thin paper is held by using the rear drum as a suction drum, and when the leading edge of the thin paper is wound around the core, the thin paper is cut from the rear drum. Conversely, air is blown out to wrap the tip of the thin paper around the core after gluing, so the tip of the thin paper can be securely attached to the core, and the adhesive applied to the core is prevented from protruding from the wrapped paper. This eliminates the risk of dirt on the rider roll and generation of noise caused by adhesive extrusion, and since the paper is wound around the core without reversing the rear drum after cutting the paper, the winder is stopped for a longer period of time. It is possible to achieve excellent effects such as being able to shorten the time and improve the operating rate.
