Description

  The present invention relates to a thin paper cutting method, and more particularly to a thin paper cutting method and mechanism of a thin paper winding apparatus.

  A typical conventional thin paper winding apparatus mainly includes an upper winding roller, a guide plate, a lower winding roller, and a pressing roller. The guide plate is arranged near the lower side of the roller surface of the upper winding roller, and a chute is formed between the guide plate and the upper winding roller. A winding portion is formed between the upper winding roller, the lower winding roller, and the pressing roller.

  In general, the paper tube of the thin paper winding device is first transported to the side of the upper winding roller by the transport device, then pushed into the guide plate chute by the push rod, and then reaches the winding portion. Next, a thin paper is wound on the paper tube, and a paper roll such as toilet paper is formed. After the winding operation of the paper roll is completed, the thin paper is pulled and cut by the speed difference generated by controlling the rotational speed of the rotary arm to be faster or slower than the rotational speed of the upper winding roller.

  In another conventional technique, there is a contact-type thin paper tension cutting method and mechanism. For example, when the rotating rod is brought into contact with the upper winding roller surface arranged in the thin paper winding device and the thin paper passing through the upper winding roller surface is pressed, the thin paper is pulled by the paper roll formed in the winding unit. In response, it is tension cut.

  However, in the above-described conventional thin paper winding device, the thin paper cannot be pulled and cut using the speed difference unless the rotational speed of the rotary arm is different from the rotational speed of the upper winding roller. When the thin paper is made of a high toughness material, the thin paper cannot be tension cut unless the speed difference between the rotating arm and the upper winding roller is increased. In general, a thin paper winding device is usually provided with a punching device in front of a chute to which the thin paper is transported, and the thin paper is punched first, so that the thin paper is placed at a predetermined position in the subsequent thin paper winding process. Can be pulled and cut smoothly. However, this complicates the structure of the thin paper winding device.

  The driving mechanism (not shown) drives and rotates the rotating rod 142 with the rotating shaft 141 as the center of rotation. The rotation direction I3 of the rotating rod 142 is the same direction as the rotation direction I2 of the upper winding roller 12. That is, when the thin paper contact end 142b of the rotating rod 142 rotates to the contact position A, the rotation direction I3 of the thin paper contact end 142b of the rotation rod 142 is opposite to the rotation direction I2 of the upper winding roller 12.

The protruding length of the cutter 144 is a length that slightly protrudes from the rotation locus circle 142 d of the rotating rod 142.

  The thin paper contact end 142b of the rotating rod 142 is provided with an auxiliary suction port 142f between the suction port 142c and the cutter 144, in addition to the suction port 142c. The auxiliary suction port 142f also communicates with the hollow chute 142e. When the rotation locus circle 142d is used as a reference, the auxiliary suction port 142f is preferably formed at a position slightly lower than the protruding length of the cutter 144.

  Reference is made to FIGS. 4 to 12 are side views showing how the thin paper cutting structure of the thin paper winding device according to one embodiment of the present invention cuts the thin paper. The rotating rod 142 is driven by the driving mechanism 143 to rotate along the rotation direction I3, and the thin paper contact end 142b of the rotating rod 142 rotates periodically in the direction of the contact position A of the upper winding roller 12 (see FIG. 5). ). At this time, the thin paper contact end 142 b of the rotating rod 142 contacts the thin paper 4. Further, the suction port 142 c of the thin paper contact end 142 b of the rotating rod 142 sucks the thin paper 4.

  As shown in FIG. 5, when the thin paper contact end 142b of the rotating rod 142 rotates to the contact position A, the thin paper contact end 142b of the rotating rod 142 adsorbs the thin paper 4, and the upper surface of the thin paper 4 is Close contact with the roller surface of the lower half. In another embodiment of the present invention, when the thin paper contact end 142b of the rotating rod 142 is at the contact position A, the thin paper contact end 142b only adsorbs the thin paper 4 and has a predetermined amount between it and the upper winding roller 12. The interval is maintained, and the thin paper 4 is not brought into contact with the lower half roller surface of the upper winding roller 12.

  Next, the second paper tube 6 is conveyed by the receiving plate 171 of the paper tube conveying device 17 and reaches the entrance of the chute 3 formed between the guide plate 13 and the upper winding roller 12. Thereafter, the second paper tube 6 is pushed into the chute 3 as the push plate 172 of the paper tube transport device 17 rotates (see FIG. 6).

  The thin paper 4 is adsorbed by the suction port 142c of the thin paper contact end 142b of the rotating rod 142, and at the same time is adsorbed by the auxiliary suction port 142f located next to the suction port 142c, thereby forming a curved shape. (See FIG. 6). Thereby, the bottom surface of the thin paper 4 is stably adsorbed by the thin paper contact end 142 b of the rotating rod 142.

  When the rotating rod 142 rotates by a predetermined angle in the rotation direction I3, the right end of the thin paper 4 is pulled and tensioned by the tensile force by the paper roll 51 formed on the winding part 19. At this time, the cutter 144 arranged on the rotating rod 142 is brought into close contact with the thin paper 4 to cut the thin paper 4 (see FIGS. 7 and 8). Further, the cut portion of the thin paper 4 is divided into a terminal portion 43 close to the first paper tube 5 and a start end portion 44 close to the second paper tube 6. The end portion 43 of the thin paper 4 is wound around the first paper tube 5 and the winding of the paper roll 51 is completed.

  At the same time as the thin paper 4 is cut, the thin paper contact end 142b of the rotating rod 142 sucks the starting end portion 44 of the thin paper 4 by the intake device. Further, since the rotating rod 142 rotates in the reverse direction at the contact position A, the starting end portion 44 of the thin paper 4 is guided to the second paper tube 6 that has just entered the chute 3. Thereby, the starting end portion 44 of the thin paper 4 is slightly wound around the outer annular surface of the second paper tube 6 (see FIGS. 7, 8, 9 and 10).

  After the rotating rod 142 rotates and separates from the thin paper 4 and the chute 3, the second paper tube 6 continues to roll forward along the chute 3, and the start end 44 of the thin paper 4 is on the second paper tube 6. Completely wrapped around. At the same time, the end portion 43 of the thin paper 4 is wound around the paper roll 51, and the winding of the paper roll 51 is completed (see FIGS. 11 and 12).

  The second paper tube 6 is conveyed to the winding unit 19 due to the speed difference between the upper winding roller 12 and the lower winding roller 15 that is generated when the rotation speed of the lower winding roller 15 is reduced (FIG. 12). And a new paper roll winding operation is started. The completed paper roll 51 is discharged along the inclined chute 23.

  At this time, the paper roll 51 has already been discharged along the inclined chute 23. The pressing roller 16 is connected to the swing arm 161 (see FIG. 1 at the same time). Since the swing arm 161 includes a rotation center shaft 162 and can swing about the rotation center shaft 162, the pressing roller 16 connected to the swing arm 161 also follows the swing locus of the swing arm 161. Move up and down. Thus, after the paper roll 51 is discharged, the pressing roller 16 that was originally in press contact with the paper roll 51 moves downward and presses against the second paper tube 6.

  The cutter 144 described above is a member that actually cuts the thin paper 4. The cutter surface 144a of the cutter 144 can be linear. Moreover, you may design to a sawtooth-shaped structure (refer FIG. 13), and, thereby, can cut the thin paper 4 still more smoothly.

  While preferred embodiments of the present invention have been disclosed above, so that those skilled in the art can practice them, they are not intended to limit the invention in any way. Various changes and modifications can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the claims of the present invention should be construed broadly including such changes and modifications.
