Description

The present invention relates to a cutting method and a cutting device, and more particularly to a method and a device for automatically cutting a paper to a predetermined length.

2. Description of the Related Art At present, paper for separating and removing solid particles from a liquid or a solid is used in a wide range of technical fields. Such paper is made of various materials to suit the purpose of use,
Moreover, it is formed in various shapes. Generally, industrial paper is stored in a container after being formed into a predetermined shape,
Used as an overload device. In a filter used as an air filter of an automobile engine, paper is formed into a circular shape as a filter element.

A filter element that has been conventionally manufactured is formed into a circular shape by forming a band-shaped paper into a fold shape, cutting it into a predetermined length, and adhering the cut ends to be housed in a container. It Therefore, the paper must be cut to length when the filter element is manufactured.

In a conventional apparatus for forming a paper having a large number of folds, for example, as shown in JP-B-57-7806, two mark thrusting rollers for forming a fold line on the paper and a mark thrusting roller for this are used. Two facing rollers facing each other and pressed from opposite sides of the strip, two drive rollers arranged behind the marking roller and for moving the strip, and arranged behind these drive rollers and It has a guide path having two smooth surfaces that gradually converge in the traveling direction, and a large number of guide ribs that are provided on the two converging surfaces and that become higher in the traveling direction.

Further, in Japanese Patent Laid-Open No. 61-291015, a ridge portion of the filter element is closed at one end portion to open a valley portion, and at the same time, the other end portion of the fold portion is opened. Thus, the troughs are closed to allow the liquid to flow not only from the upper surface of the pleated portion of the excess element but also from one end of the pleated portion, and flow out to the lower surface of the pleated portion and the other end. In this excess element, it is possible to secure a wide fluid passage surface inside and outside the excess element, and only the liquid flows along the folds of the overelemet, and flows diagonally in each fold,
There is no sudden change in the flow direction of the fluid. Therefore, the flow resistance of the fluid can be reduced.

Problems to be Solved by the Invention A filter element formed by the above conventional device is
Since it has a structure that retains the shape of the filter element with the strength of the paper itself, it has a shape that is easily deformed, which is not only inconvenient to handle, but it may be deformed during use as a filter element. . A conventionally manufactured filter element, after being formed into a predetermined shape, expands slightly due to its elasticity when housed in a container. In this state, the folds formed on the paper also partially expand. Therefore, a portion with a large fold spacing and a portion with a small fold spacing are formed. This causes the fluid flow through the filter element to be partially non-uniform.

On the other hand, the Applicant has developed an over-element which holds the filter element in a predetermined shape by applying an adhesive to the paper. This overelement is disclosed in Japanese Patent Laid-Open No. 61-291015.
In order to apply the adhesive to the paper to form the filter element in a predetermined circular shape, it is necessary to manufacture the filter element in consideration of characteristics such as paper quality and folding structure of the paper. However, conventionally, no device for cutting the paper coated with the adhesive into a predetermined length has been proposed, so that the overelement developed by the present applicant could not be automatically manufactured.

Further, the paper is formed into a pleated filter element having a crest and a trough, but when the paper is cut to a predetermined length, it is necessary to cut at the top of the crest of the paper or the bottom of the trough. . This means that when the both ends of the cut paper are adhered to form a circular shape, the adhesive surface is not well formed unless the paper is cut at the tops of the peaks or the bottoms of the valleys. On the other hand, there are disadvantages that the non-adhesive ears are formed in the cut portion, the adhesion is incomplete, and the effective length of the paper to be adhered becomes uneven. However, the prior art cannot accurately and automatically cut the paper at the tops of the peaks or the bottoms of the valleys. Therefore, there has been a demand for a technique of accurately cutting a paper into a predetermined length and molding a pleated filter element at a high speed.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an automatic paper cutting method and a paper cutting device which can eliminate the above-mentioned drawbacks and can cut paper accurately with a predetermined length.

An automatic paper cutting device according to a fourth invention of the present application is characterized in that a heating device for softening the adhesive adhered to the adhesive surface of the paper to be cut in the second invention is provided.

When a predetermined number of peaks or valleys are counted at the working measurement position,
While moving the blade in the same direction as the moving direction of the paper at the same speed as the paper conveyance speed at the cutting position away from the measurement position by a constant distance, the rotating blade cuts the crests or troughs of the paper, The paper is cut accurately in a predetermined length.

Further, since the counting device counts a predetermined number of peaks or troughs of the paper, the cutting position of the paper can be accurately detected. Furthermore, since the blade is moved with respect to the paper by the blade moving device at the same speed as the paper conveying speed, the cut portion of the paper is formed in a straight line perpendicular to the length direction of the paper.

Since the position detection sensor detects the position of the crests or troughs of the paper more accurately, it is possible to cut the paper along the linear recesses formed on the tops of the crests or the bottoms of the troughs. .
