Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for manufacturing toilet roll paper, and more particularly to a method and an apparatus for manufacturing a compact roll-type toilet roll paper which is not bulky.

[0002]

2. Description of the Related Art Roll-type toilet roll paper is rolled into a roll shape on a cylindrical core so that the toilet roll paper can be continuously and smoothly taken out from a holder at the time of use. Has been made.

[0003]

However, the fact that the outer shape of the side face is cylindrical and that the hollow core has a hollow core causes a large number of gaps during loading, storage, etc. . Because of such a shape, the conventional roll-type toilet roll paper is bulky and therefore has a high freight charge and a storage fee such as a warehouse, and cannot be ignored in terms of unit price. Moreover, when exporting overseas, the freight and storage fees are enormous, and there is a large amount of rebound to the unit price, and these savings have been a major issue for the time being.

[0004]

Means and Actions for Solving the Problems The present invention solves the above problems and is technically very valuable. That is, according to the present invention, the toilet roll paper is compressed in one direction until it has a flat side shape whose width is at least about 3 times the thickness, and the entire compressed toilet roll paper is covered with a film. In a method for producing a flat compressed toilet roll paper, which is characterized in that the present invention is:
Toilet roll paper roll receiving device, toilet roll paper roll cutting device, toilet roll paper roll compression molding device and compressed flat toilet roll paper film coating device, at least for thickness It is an apparatus for manufacturing a flat compressed toilet roll paper having a lateral shape having a width of about 3 times.

By the way, in the prior art, the roll type toilet roll paper is, for example,
It is considered that the product value is deteriorated even if it is deformed into a distorted shape, and it is generally considered to be avoided. Therefore, it can be said that the present invention is contrary to the conventional general idea. However, for example, even if the conventional roll-type toilet roll paper is intentionally pressure-formed into a flat shape, the toilet paper originally has wrinkles or is embossed to have flexibility. Since it is provided, since it can be easily restored to a cylindrical shape by pushing back the bent portions on both sides, it does not cause any trouble even if it is used for a roll type toilet roll paper holder. The present inventor arrived at the present invention by paying attention to such a soft property of the roll-type toilet roll paper.

In the description of the present specification, the term "flat shape" refers to a shape that is flatter than a circle, and includes not only ellipses and rectangles but also various shapes that can be taken during the transformation from a rectangle to an ellipse. . In particular, regarding the side surface shape of the toilet roll paper of the present invention, various shapes such as an ellipse or a rectangular shape can be used, but a substantially rectangular shape with rounded corners is used without wrinkles at the corners. It is preferable in terms of molding or molding. The shape of the toilet roll paper of the present invention is formed by pressure molding, but it is preferable to apply pressure simultaneously with film sealing. Therefore, for example, only by applying pressure from the vertical direction, it is possible to form an appropriate side surface shape by applying pressure not only from the vertical direction but also from the horizontal direction at the same time.

The toilet roll paper of the present invention is
Not only one toilet roll paper but also one having a perforated length so that it can be broken may be used. Further, although the core is not necessarily required, it is easy to restore the flat shape to the cylindrical shape by providing the hollow core having elasticity even slightly.

The hollow core material used in the roll type toilet roll paper of the present invention can be easily restored from a flat shape, particularly a thin flat shape to a circular shape, that is, a cylindrical shape. It is enough, for example,
It may be an elastic material such as rubber or plastic rubber that can be easily restored to a cylindrical shape by unwrapping, and it may be easily deformable and flexible, that is, slightly elastic, such as a paper tube core. It may be of material. For example, with respect to a roll type toilet roll paper using a conventional paper tube core, when subjected to a flat pressure forming process, the paper tube core forms a wrinkle on its bent side. This is not a problem because it is possible to easily form a cylindrical shape, that is, a roll shape by lightly applying force to the side portion and inflating the central portion.

Therefore, the flattened toilet roll paper according to the present invention can also be produced by flatly pressing a general roll type toilet roll paper. However, as described above, the roll-type toilet roll paper that is pressure-molded into a flat side surface, that is, an ellipse or a rectangle, has a considerable restoring force even after molding, so in order to maintain the shape at the time of molding, At the same time, it is necessary to wrap in plastic film or the like.

The flattened toilet roll paper can be packaged in addition to plastic film packaging.
Any packaging such as a paper container, a plastic container, a can, etc. can be used. In particular, the packaging by the plastic film is easy to mechanize, so that film sealing, particularly individual film sealing, is easy, and moreover, it is hermetically sealed. Since it is possible to prevent contamination or deterioration due to rain, moisture, etc. during transportation or storage, it is extremely hygienic. Moreover, in the case of flatly pressing and film-wrapping, by pressing and sealing under vacuum, it is possible to compress to half the volume of a normal roll-type toilet roll paper,
Moreover, the restoring force is large relative to the volume, which is preferable.

Since the hollow portion 3 of the core is drawn in a much exaggerated manner, the void is shown to be quite large. However, in the case of a paper tube core, the inner wall surfaces of the hollow portion of the core are almost in contact with each other and the gap is Even if it occurs, it is slight. However, depending on the material of the core and the conditions of the molding / sealing process, the hollow part of the core of the flat toilet roll paper according to the present invention is from a state with a gap to a state with almost no contact with the gap as shown in the figure. There are various possibilities. FIG. 2 is a process drawing showing an embodiment of the manufacturing method and manufacturing apparatus of the present invention.

The roll 8 of the manufactured roll-type toilet roll paper is sent from the roll receiving step 4 by the conveyor belt 7 to the cutting step 5 by a cutter, for example, a round blade automatic cutter, and cut into an appropriate length. It In the cutting step 5 using a cutter, the roll 8 of the roll-type toilet roll paper can be cut into a suitable length and perforated so that it can be broken.
In FIG. 2, only the roll-type toilet roll paper 9 cut to the use length is shown, but it may be a roll-type toilet roll paper roll that is perforated so that it can be appropriately broken to the use length. .

In the conventional method, the roll-type toilet roll paper cut in the cutting step is film-packed in the form of the same and then packaged by boxing or the like before being shipped. -It is sent to the sealing step 6, molded into a flat shape, and sealed with a film.

The roll type toilet roll paper 9 cut in the cutting step 5 is formed by the conveyor belt 7.
It is sent to the sealing step 6. On the other hand, in the molding / sealing process, the packaging plastic films 13 and 14 are unrolled from the delivery film rollers 11 and 12 and sent to the molding / sealing unit 21 via the guide rolls 15 and 16 and the guide plates 17 and 18. The cut roll-shaped toilet roll paper 9 is sent to the molding seal portion 21 together with the lower film 14. Further, the upper film is sent via the upper guide plate, and is hung on the forming / sealing portion 21 or in front of the forming / sealing portion 21 so as to cover the upper portion of the cut roll-shaped toilet roll paper 9.

The molding / sealing portion 21 is provided with pressure molding presses 19 and 20 equipped with a means for sealing the film. (Not shown). The cut roll-type toilet roll paper 9 is fed into the opposing limiting frame, and is pressed by the presses 19 and 20 from above and below under the condition that the upper and lower films are hung, and the film is formed at the same time as molding. Sealed.

The limiting frame may be fixed, but it is preferable that the facing distance can be adjusted appropriately. By providing the limiting frames at appropriate intervals, the lateral pressing action can be adjusted, and various flat shapes can be formed. The toilet roll paper, which is sealed with a film at the same time as molding, is transferred from the molding / sealing unit 21, sent from the belt conveyor 22 to the chute 23, and packed in a cardboard box or the like for shipment.

In FIG. 2, in the molding / sealing process,
An example was shown in which one piece of cut toilet roll paper was pressed and simultaneously sealed with a film.
A plurality of sheets may be simultaneously pressure-molded and packaged and sealed in one pack by a film, and the same can be applied to a roll of long toilet roll paper. Of course, the molding and sealing steps can be separated and performed separately. In this case, a film is hung on each of the flat toilet roll papers, which have been subjected to only the pressure forming process, or a plurality of them, to seal them.

FIG. 3 is a diagram showing an outline of a pressure molding step in another embodiment of the method and apparatus for manufacturing toilet roll paper according to the present invention. The roll-type toilet roll paper 24, which is perforated and cut to an appropriate length in the cutting step (not shown), is formed by the plastic film delivered from the plastic film delivery roller 25 (the lower roller is not shown).
