DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to manufacture a toilet paper roll in which the core portion is made of toilet paper, that is, without using a core made of a paper tube, the starting portion of the toilet paper is made into a core portion. Toilet
The present invention relates to a paper roll manufacturing apparatus .

[0002]

2. Description of the Related Art In recent years, toilet paper rolls have been impregnated with a deodorant for eliminating an unusual odor of the toilet and an aromatic for generating a good odor in the toilet.
That is, in a cored toilet paper roll in which the start portion of toilet paper is wound around a paper cylinder, the paper cylinder is impregnated with a deodorant or an aromatic.

[0003]

In the above-mentioned toilet paper roll in which toilet paper is wound around a paper cylinder, the paper cylinder is expensive because of the paper cylinder, and the paper cylinder cannot be flushed into a faucet toilet after use. Because it takes time and effort to throw it away,
Recently, toilet paper rolls using a toilet paper itself as a core without using a paper cylinder have been developed.

In a toilet paper roll without such a paper cylinder, the paper cylinder cannot be impregnated with a deodorant or an aromatic. In addition, in order to impregnate the toilet paper itself with the deodorant or the fragrance, there is a problem that the number of steps is increased and the cost is increased.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to spray an aqueous solution of a deodorant or a fragrance in place of conventional water at the beginning of winding toilet paper. , in and can be manufactured toilet paper roll in the same process as the conventional manufacturing process providing St. toilet paper roll production apparatus attained a reduction in cost.

The illustration of a transport mechanism for transporting from 7L, 7R or gluing rollers 7L, 7R to the press fitting 11 is omitted.

Next, the manufacture of the toilet paper roll will be described. First, for example, a plurality of winding pegs 2 are put in a thermostat at 50 ° C. to 60 ° C.
Heat to 60 ° C. Next, 1 heated to 50 ° C to 60 ° C
The roll 2 is placed on the winding rollers 1L and 1R, and the holding roller 3 winds the roll 2
L, 1R, while being pressed against the take-up roller 1L,
By rotating the 1R in the counterclockwise direction, a plurality of toilet papers S start to be wound around the outer circumference of the pongee 2.

As described above, when the toilet paper S starts to be wound around the winding shaft 2, the slitter 5 cuts the toilet paper W unwound from the raw roll into a plurality of toilet papers S. Then, at the initial stage of winding the toilet paper S on the winding shaft 2, that is, while the toilet paper S is wound on the winding shaft 2 by about 1 to 10 layers, a deodorant or (and) an aromatic agent from the spray nozzle 6 to the toilet paper S. Spray the aqueous solution of

Next, when the toilet paper S is wound around the winding shaft 2 by about 1 to 10 layers, the spraying of the aqueous solution from the spray nozzle 6 onto the toilet paper S is stopped.
The diameter of the toilet paper roll R is, for example, 115 m
Take up the toilet paper S until it reaches m. When the diameter of the toilet paper roll R becomes 115 mm, the rotation of the winding rollers 1L and 1R is stopped, and the winding of the toilet paper S is completed.

Next, the toilet paper roll R on the winding rollers 1L, 1R is transferred onto the gluing rollers 7L, 7R together with the winding shaft 2, and the end end of the toilet paper S wound is cut by the terminal cutter 8. Then, after the paste is sprayed from the paste spray nozzle 9 to the inside of the winding end of the toilet paper S, the paste roller 7L, 7
By rotating R in a counterclockwise direction, for example, for several tens of seconds, the winding end of the toilet paper S is temporarily adhered so as to be peelable.

Next, the toilet paper roll R on the pasting rollers 7L and 7R is pushed together with the winding shaft 2 by the metal fittings 11.
And roll the toilet paper roll R from the reel 2
Or a plurality of toilet paper rolls R can be obtained by fixing the toilet paper roll R and extracting the wound pongee 2. Thereafter, the similar steps are sequentially performed, whereby the toilet paper roll R can be sequentially obtained.

As described above, according to one embodiment of the present invention, at the beginning of the continuous process of winding the toilet paper S, the aqueous solution of the deodorant and / or fragrance is used so that the toilet paper S is not unwound. Is wound to form a winding core portion, and the outer periphery of the winding core portion is provided with a winding portion in which a normal toilet paper S is wound up and a winding end end is temporarily adhered. A paper roll R can be obtained. Therefore, since a paper core is not required, the toilet paper roll R can be manufactured inexpensively and without trouble.

Further, the toilet paper S of the winding shaft 2
Since the peripheral surface on which is wound is coated with polytetrafluoroethylene, the core 2 can be pulled out without deforming the core by the drying of the core and the lubricating action of the polytetrafluoroethylene. Further, since the core is adhered with an aqueous solution of a deodorant or an aromatic agent, it is soluble in water, so that the core can be flushed to a flush toilet after using the toilet paper S, and the treatment of the core can be performed. Will not be troubled.

FIGS. 3A and 3B are explanatory views showing another example of a winding shaft used in an embodiment of the present invention. In FIG. 3, reference numeral 2A denotes a metal winding shaft, which is composed of a left part 21 divided into two parts and a right part 2r, and a concave part 2o is provided in the left part 21 and a concave part 2o is provided in the right part 2r.
Is provided with a projection 2p that fits into the projection. Therefore, by fitting the projection 2p of the right part 2r into the concave part 2o of the left part 21, one winding shaft 2A can be obtained. In addition, the toilet paper S of the winding shaft 2A is wound up.
The peripheral surface is coated with polytetrafluoroethylene.

When the winding rod 2A is configured as described above, the winding shaft 2A can be divided into two and shortened, so that the depth of a heating device such as a thermostat for heating the winding shaft 2A is shortened. be able to.

[0022] FIG. 4 is an explanatory view showing still another example of the winding shaft to be used in this onset Ming embodiment. In FIG.
Reference numeral 2B denotes a winding shaft, which includes a metal shaft portion 2x and the shaft portion 2x.
x and a terminal 2t provided on the shaft portion 2x and supplying power to the heater 2h. The peripheral surface of the winding shaft 2B around which the toilet paper S is wound is coated with polytetrafluoroethylene. The heater 2 is attached to the shaft 2x.
h, terminal 2t is insulated.

When the winding shaft 2B is laid horizontally in this manner, by supplying power to the terminal 2t, the winding wire 2B can be heated to a desired temperature, so that a heating device such as a thermostat is not required.

In the above embodiment, the toilet paper W fed from the raw roll is cut into a plurality of toilet papers S by the slitter 5, and then the plurality of toilet papers S are wound on any of the wound pongs 2, 2A, 2B. As described above, the toilet paper W is wound around the winding shafts 2, 2A, 2B as it is, and then the long toilet paper roll from which the winding shafts 2, 2A, 2B are pulled out is cut to form a plurality of toilets. Paper roll R
It may be.

Although the example in which the peripheral surface of the winding shafts 2, 2A and 2B around which the toilet paper S is wound is coated with polytetrafluoroethylene, it is possible to coat or wind a material having the same lubricity as that which functions similarly. Good.
