BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an edge removing device for a toilet paper winder.

[0002]

2. Description of the Related Art A conventional edge removing device for a toilet paper winder will be described with reference to FIGS.

A typical toilet paper take-up machine currently used is divided into a paper feed processing part and a take-up part. The paper feeding processing part is paper-made by a paper machine and usually has a diameter of 1000 to 1500 mm. A part where the toilet paper is unwound from the rolled up roll and is subjected to paper processing if necessary and supplied to the winding part. The winding part is a part for winding the toilet paper sent from the paper feed processing part on the winding shaft to manufacture a roll-shaped coreless toilet paper, and FIG. 3 shows only the winding part. Has been done.

As shown in the figure, the winding part is mainly composed of drive rolls 2, 3, a riding roll 4, a nip roll 5, a cutter 6 and the like. Then, in this winding part, the riding roller 4 is rotated while rotating the driving roller 2 and the driving roller 3.
Then, when the toilet paper roll T on the winding shaft 1 is pressed, the toilet paper P fed on the winding shaft 1 is wound up.

In the figure, the state of the beginning of winding the toilet paper P is shown, and the width from the original roll is 1000 to 20.
The toilet paper P, which is as wide as 00 mm, is fed, but it is cut to a paper width of 114 mm defined by the JIS standard by several cutters 6 arranged side by side. 7
Is a cradle for receiving the rolled toilet paper roll To, and 8 is a knife for cutting the toilet paper P in the width direction.

When the toilet paper roll To, which has been wound up first, is placed on the pedestal 7, the toilet paper P is cut by the knife 8, and the paper P in the portion shown by the broken line is shown by the solid line 1 Wrapped around. Then, water w for temporary adhesion is sprayed from the sprayer 9, the riding doll 4 descends, and the drive rolls 2 and 3 start to rotate. Since the paper P temporarily adheres to the winding shaft 1 and the winding layers of the paper P due to the adsorption action of water, the toilet paper P is wound by the rotation of the driving rolls 2 and 3, and the winding diameter is gradually increased. .

As shown in FIG. 4, when the winding diameter increases to some extent, the spray of the sprayer 9 is stopped, and when the winding diameter reaches 120 mm defined by JIS standard, the winding is completed.

From the start to the end of this winding operation, the edge edge Pe of the toilet paper P fed on the surface of the drive roll 2 is cut by the edge edge cutter 6, and the nip roll 5 is moved to the left side in the figure. The suction duct 50 provided is used for suction.

[0009]

By the way, the above-mentioned conventional example has the following problems. First, since the water sprayed at the beginning of winding adheres also to the surface of the drive roll 2, the edge Pe cut off by the cutter 6 sticks to the surface of the drive roll 2 to form a dumpling, or the drive roll 2 It often happened that it did not go over the upper surface of the and dropped sideways from the middle, and that it could not be sucked in by the suction duct 50.

Further, after being cut by the cutter 6, it once rides over the upper surface of the drive roll 2 and then descends downward to be sucked by the suction duct 50.
Sometimes, the band of the edge of the ear Pe may be cut off when the width of is narrow. In this way, if the band of the ear end Pe is cut off in the middle, it will not automatically climb over the upper surface of the drive roll 2, so it is necessary to manually carry the ear end Pe to the suction duct 50. It was

In view of such circumstances, it is an object of the present invention to provide an ear end removing device in which the ear end can be surely discharged to the outside by a suction duct.

[0012]

SUMMARY OF THE INVENTION A toilet paper edge removing device according to the present invention comprises a drive roll that rotates while contacting the toilet paper wound around a winding shaft to drive the toilet paper to wind. A toilet paper winder comprising a cutter that cuts the edge of a raw sheet that is fed along the surface of a roll, wherein an edge suction duct is provided between the upper surface of the drive roll and the cutter. A doctor is provided at the tip of the suction duct, which is in contact with the surface of the drive roll and scrapes off the edge of the ear.

[0013]

In the present invention, since the suction duct is arranged in front of the upper surface of the drive roll, that is, on the cutter side, it is not necessary for the strip-shaped ear end separated by the cutter to cross over the upper surface of the drive roll. , Even if water is attached to the surface of the driving drum, it does not drip or hang down from the middle.

Further, since the edge of the ear is scraped off by the doctor, the edge of the ear is continuously guided by the doctor to the suction duct even when the edge of the ear is cut off. For this reason, the ear end can be reliably discharged to the outside of the machine without requiring manpower.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, reference numeral 10 is a suction duct, and a J-shaped curved doctor 11 is formed at the tip of the suction duct 10. The rear end of the suction duct 10 is connected to a suction means such as a blower. Although the material and manufacturing method of the suction duct 10 are not limited in principle, it is easy to mold a vinyl chloride pipe, for example. The tip of the doctor 11 is attached so as to be almost in contact with the surface of the drive roll 2. The position is closer to the cutter 6 than the upper surface of the drive roll 2.

As shown in FIG. Next to the cutter 6, a cutter 6a of the same type is attached, which is for cutting the toilet paper roll T to 114 mm which is a JIS standard. The cutters 6a are provided in the required number according to the width of the raw paper P. In addition, a similar cutter 6 is also provided at the end not shown in FIG.
And a suction duct 10 for removing the edge of the ear.

As is clear from the figure, in this embodiment, the ear end is
Before the Pe moves to the upper surface of the driving drum 2, it is scraped off by the doctor 11 and sucked into the suction duct 10, so even if the surface of the driving drum 2 is wet with water, the tip of the ear is cut off in the middle. Even so, the suction duct 10 can be surely sucked up and discharged out of the machine.

[0019]

EFFECTS OF THE INVENTION According to the present invention, the ear end can be reliably discharged to the outside of the machine.
