  However, when water is used as the liquid in the paper roll winding device described above, there are the following problems.

(i) The adhesive strength of water is weak and may not adhere depending on the condition of the base paper.
(ii) Since the adhesive strength of water is weak, the rotation speed of the winding shaft cannot be increased. (The base paper does not wind around the take-up shaft.)
(iii) When the water runs out (less), the required adhesion is insufficient and the base paper may not adhere to the take-up shaft. If there is too much water, the paper roll becomes soaked and the original paper structure may be dissolved. Thus, it is difficult to adjust the amount of water.
(iv) The appropriate amount of spray water varies depending on the degree of drying of the base paper, and it is troublesome to adjust it each time.
(v) If the base paper is too dry, the base paper may be hard and plate-like, and the base paper will not adhere to the take-up shaft.
(vi) When the base paper is separated from the front and rear surfaces of the winding shaft and is not in contact with the surface, the base paper does not wind around the winding shaft.

  That is, when the base paper is wound around the take-up shaft 202, as shown in FIG. 4B, it is sufficient that the base paper comes into contact with the outer peripheral surface of the take-up shaft 202 at the position P2, and winding is started. If the position is P1 or P3, the base paper does not wind around the winding shaft 202, and a winding error occurs.

Rotated paper A take-up device Lumpur.

  In the illustrated example, the suction holes 102a and 102b are provided on the upper outer peripheral surface 106 of the take-up shaft 50. However, the base paper P only needs to be adsorbed to the outer peripheral surface of the take-up shaft 50 by suction. As long as the base paper P is attracted to the outer peripheral surface of the take-up shaft 50, there are no particular limitations on the installation locations of the suction holes 102a and 102b on the outer peripheral surface of the take-up shaft 50.

  In the illustrated example, the liquid ejecting device 44 having the liquid ejecting nozzle 46 is provided as the liquid ejecting means 40. However, the liquid ejecting means 40 may be provided as necessary. Moreover, as the said liquid ejection means 40, the structure of patent document 3 is employable, for example. In addition, water is suitable as the liquid W ejected by the liquid ejecting means 40, and water is used as the liquid W in the illustrated example.

  The base 4 is a member serving as a pedestal for various equipment constituting the paper roll winding device 2 of the present invention. A recess 6 is formed below the winding shaft 50, and the bottom of the winding shaft 50 is below the tip. An outward inclined portion 5 is formed on the side (see FIGS. 1 and 2). The concave portion 6 is a portion for receiving the liquid W to be dropped when the liquid W is sprayed onto the winding shaft 50 by the liquid ejecting means 40. Further, the outward inclined portion 5 is a portion for allowing the paper roll PR discharged from the winding shaft 50 by the roll discharging means 80 and falling on the base 4 to roll outward from the base 4. is there. Although not shown, if a container for storing the paper roll PR is disposed below the outer inclined portion 5, the paper roll PR discharged from the take-up shaft 50 by the roll discharging means 80 is removed from the base 4. The side inclined portion 5 rolls down and fits in the storage container.

  As shown well in FIG. 1, the frame 10 is a support frame that is erected on the upper portion of the base 4, and the two side plates 12a and 12b are fixed to the base 4 at the base, and the two side plates are fixed. Reinforcing pipes 13 and 15 are horizontally placed between 12a and 12b. Protrusions 12a2 and 12b2 projecting forward are formed on the side plates 12a and 12b, respectively.

  A rear roller 18 and a front roller 19, which are a pair of rollers horizontally mounted on the frame 10, are installed between the two side plates 12a and 12b in a rotatable state (see FIG. 1). ). The rear roller 18 is pivotally supported by the rear portions of the side plates 12a and 12b via a rotation shaft 18a, and the front roller 19 is a projecting end portion 12a2 and 12b2 protruding forward of the side plates 12a and 12b. It is pivotally supported via a pivot shaft 19a. An upper roller 17 is pivotally supported above the rear roller 18 via a pivot shaft 17a. The upper roller 17 is a roller for pressing and clamping the base paper P with the rear roller 18.

  An endless transport belt 20 is wound between the rear roller 18 and the front roller 19, and a drive motor (not shown) is housed in a housing attached to the side surface of the side plate 12b. When the rear roller 18 is rotationally driven by the drive motor in the housing, the transport belt 20 is also driven to transport the base paper P forward. The take-up shaft 50 can be driven to rotate by a drive motor 60 via a drive pulley 64. Since the basic configuration of each part of these devices is disclosed in Patent Document 3, detailed description thereof is omitted.

  Accordingly, when the base paper P dried by the dryer part of the waste paper recycling apparatus for document shredder (see Patent Document 2 to Japanese Patent Application No. 2010-212055) is introduced into the paper roll winding device 2 of the present invention. The base paper P is conveyed forward by the conveyor belt 20 while being pressed and clamped by the rear roller 18 and the upper roller 17.

  In the illustrated example, a commercially available vacuum pump having an intake hole 108 and an exhaust hole 110 is used as the negative pressure generating means 104. As well shown in FIG. 3A, the negative pressure generating means 104 generates negative pressure in the suction holes 102 a and 102 b to suck the raw paper P, so that the raw paper P is on the upper outer peripheral surface of the take-up shaft 50. The wire is wound along the line 106. Note that it is sufficient that at least one suction hole is provided, and the number is not particularly limited.

  In this way, negative pressure is generated in the suction holes 102a and 102b by the negative pressure generating means 104 and the base paper P is sucked. Therefore, as shown in FIG. Even if it is in the position, the base paper P is sucked and adsorbed to the take-up shaft 50, so that it is possible to prevent a take-up error when the base paper P is taken up by the take-up shaft 50.

  Further, in the illustrated example, as well shown in FIG. 3 (c), it is provided on the rear side of the winding device 2 with respect to the winding shaft 50, and air A is blown against the base paper P to prevent the base paper P from moving away. Air jetting means 112 is provided, and the base paper P is wound along the lower outer peripheral surface 114 of the winding shaft 50 by the air A from the air jetting means 112.

  Further, the suction hole 108 of the negative pressure generating means 104 is connected to the suction holes 102a and 102b, and the exhaust hole 110 is connected to the air ejection means 112. Thereby, due to the double effect of the intake and exhaust of the negative pressure generating means 104, it is possible to prevent a winding error when the base paper P is wound around the winding shaft 50.

  The paper roll winding device 2 of the present invention is used in the waste paper recycling apparatus for document shredding waste as described above, and the waste paper recycling apparatus for document shredding waste is the document shredding for one roll of toilet paper. Since paper is made every time the waste accumulates or one batch of toilet paper is batch-processed, the transport belt 20 does not need to be constantly driven, and the base paper P is introduced into the apparatus 2 of the present invention. It is only necessary to start the driving when it is done.

  Since the device 2 of the present invention is preferably used in the waste paper recycling apparatus for shredded documents, it is desirable not to use as much as possible the waste, so the paper roll PR is a so-called coreless paper roll without a paper core. In this case, the winding shaft 50 is required to wind the paper roll PR without a paper core.
