Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an apparatus for manufacturing compressed toilet roll paper, toilet paper, and towel roll paper, that is, compressed roll paper, and particularly relates to a manufacturing device for compressed toilet roll paper, toilet paper, and towel roll paper. Or, it relates to a roll paper compression device suitable for reducing the volume.

(B) Prior Art In general, roll paper is manufactured into a cylindrical shape by wrapping toilet paper or towel paper around a hollow cylindrical core so that it can be continuously removed from a holder during use.

However, having a cylindrical outer shape and a hollow cylindrical core makes it difficult to load cargo.
During storage, etc., there were many gaps, which caused the bulk. For this reason, with conventional roll paper, freight charges and storage charges at warehouses and the like are relatively high, which cannot be ignored in terms of the unit price of roll paper. Moreover, in the case of export, the shipping and storage fees amount to a huge amount, and reducing these costs has been a major challenge in reducing unit prices.

(c) Problems that the invention aims to solve In order to overcome the drawbacks caused by the cylindrical shape of roll paper, a method has been proposed to deform roll paper into a flat shape to reduce costs associated with packaging, transportation, and storage. has been done.

However, at present, none of these methods has been put into practical use.

This is because roll paper is thought to reduce its product value even if it is distorted during transportation, for example, and when roll paper is compressed and deformed into a flat shape, it expands on one side. When taken out, the crepe stretches, becomes wrinkled and loses its elasticity, so even if the flat roll paper is restored to a circular shape during use, the distorted shape will not be easily resolved and will remain.
Even if roll paper is compressed and deformed into a flat shape by pressing, when the pressing force is released, the roll paper's unique elasticity allows it to easily swell and maintain its shape when compressed and deformed by pressing. Therefore, the volume reduction effect due to compressive deformation is not as great as the one shown above.

The present applicant previously filed an application for an invention for a compressed roll paper with a significant volume reduction effect, and a method and apparatus for manufacturing the same (see Japanese Patent Laid-Open No. 59-218127 and Japanese Patent Laid-Open No. 60-204554).

(d) Means for solving the problem The present invention is to easily and easily produce compressed roll paper in large quantities, without taking up a relatively large amount of space, which can be easily and easily restored to a cylindrical shape during use. The present invention provides a compressed roll paper manufacturing device suitable for mass production.

That is, the present invention includes a base member, a frame provided upright on the base member, and a lower roll paper support having a roll paper pressurizing support surface on the upper surface and fixed to the base member. an upper roll paper support member fixed to the frame above the lower roll paper support member and having a roll paper pressure support surface formed on the lower surface; and a roll paper pressure surface on the upper and lower surfaces; The apparatus for producing compressed roll paper is characterized in that it includes a pressure member of a double-sided pressure type connected to a plurality of vertically reciprocating bodies at an end portion thereof.

In the present invention, the roll paper pressing member such as a press member is of a double-sided pressure type, so that the roll paper can be compressed on the other hand while the compressed roll paper is taken out on the other hand. Pressure surfaces for the roll paper are formed on both sides of the roll paper so that the roll paper can be compressed even when moving in the direction. In this invention,
Roll paper support surfaces are provided above and below opposite the pressure surface of the roll paper pressure member.

In the present invention, the upper roll paper support surface is formed on the upper surface of the lower roll paper support member such as the lower roll paper holder, and the lower roll paper support surface is formed on the upper surface of the lower roll paper support member such as the upper fixing base. It is formed on the lower surface of the roll paper support member. This upper roll paper support member is fixed to a frame such as a column.

The reciprocating movement of the roll paper pressing member is performed by connecting a plurality of reciprocating rod members, such as a plurality of reciprocating rods, which move synchronously in the vertical direction to the end of the pressing member. This connection is performed by connecting at three or more locations, for example, at the four corners, so that the roll paper is compressed uniformly by the roll paper pressing member. The reciprocating rod member can be, for example, a rack of a rack and pinion mechanism, a hydraulic cylinder such as a hydraulic cylinder, a crank mechanism, or the like. However, the reciprocating rod member is easy to use. A simple pinion mechanism is preferable because it simplifies operation using the same power source.

When a guide member is extended from the end of the roll paper pressing member and this guide member is engaged with a guide rod such as a column and connected to a reciprocating body such as a reciprocating rod, the pressure applied by the press member to the roll paper is reduced. This is preferable because it can be made uniform.

In the present invention, by supplying the roll paper to be compressed next, the compressed flat roll paper that has already been compressed and remains in the compression space is discharged. Therefore, it is preferable that the roll paper supply path and the compressed roll paper discharge path be provided at substantially the same level. By providing a roll paper supply path and a compressed roll paper discharge path at appropriate positions in the movement path of the pressure member, the roll paper pressure member moves upward and is placed above the roll paper pressure member. While the roll paper being compressed is being compressed, the roll paper to be compressed next can be supplied to the lower compression space by roller feeding or the like. At this time, the compressed roll paper left after the previous compression is pushed out by the new roll paper and can be removed.

(e) Effect In this invention, a double-sided pressurizing type roll paper pressurizing member having pressurizing surfaces on the upper and lower surfaces is provided so as to be able to reciprocate in the vertical direction, so the pressurizing member can be moved upward to apply pressure. The roll paper placed on the upper surface of the member can be compressed by being pressed against an upper support member such as a crown or an upper fixing table fixed to the upper support member such as a crown, and the pressurizing member may be pressed downward. can be moved, for example, to compress the roll paper placed on the lower roll paper cradle, which is fixed relative to the table or base member.

In this case, when moving the roll paper pressure member downward to compress the roll paper on the bed or roll paper holder, the roll paper placed on the top surface of the roll paper pressure member has already been compressed. Therefore, when the roll paper pressure member descends to a predetermined position, the compressed roll paper placed on the top surface of the roll paper pressure member is supplied from the roll paper supply path to the top surface of the pressure member. The rolled paper that is then compressed can be pushed out and discharged from the pressing surface on the upper surface of the rolled paper pressing member.

In this way, the roll paper can be constantly compressed by the vertical movement of the roll paper pressurizing member of the double-sided pressure type, and the roll paper to be compressed next can be supplied and the compressed roll paper can be discharged. , the processing capacity per hour is large.
