Description

Unevenness giving device {IRREGULARITY PROVIDING DEVICE}

The irregularities attached to the sheet-like article have been used as wiping papers because of their excellent decorative properties and as wiping effects improve.

However, the application of the irregularities to the sheet-like article is not limited to the above-mentioned use, but there are the following uses. Wiping paper, old paper, and waste paper using uneven protrusions are used for absorbing paper such as oil, which absorbs uneven adsorption, and packing for packing materials using uneven cushioning properties. Ash and so on.

However, the process of providing uneven | corrugated to a sheet-like thing is performed on a large scale and industrially using the exclusive manufacturing apparatus. Up to now, it is difficult to easily use it as a decorative paper freely giving preference to unevenness by using a nearby material such as pattern paper, synthetic resin paper, and aluminum foil. In addition, it is difficult to provide irregularities easily using nearby waste paper, waste paper such as newspaper, or copying paper, and to provide it as a sorbent paper or wipe paper at low cost for daily use.

In order to cope with such a problem, there is a Japanese patent application (Japanese Patent Application No. 10-326133) (hereinafter referred to as "the above application") by one of the inventors and the applicant. This application describes an apparatus for applying irregularities to a sheet-like article by forming a roller by stacking a plurality of circular plates provided with irregularities on an outer periphery, and engaging the two rollers with each other to pass the sheet-like article between the rollers.

The concave-convex imparting device according to the above application can impart the concave-convex superior in unified aesthetic sense to the sheet-like article in appearance. However, since the rollers are formed by stacking a plurality of circular plates (hereinafter referred to as "circular plates with concave-convex concave and convex and concave and convex concave and convex concave and convex concave and convex concave and convex concave and convex concave and convex concave and convex concave and convex concave and convex concave and convex concave and convex concave convex concave and convex concave and concave convex concave and convex concave and convex concave and convex concave and convex concave and convex concave convex and concave convex and concave convex and concave convex and concave convex and concave convex and concave convex and concave convex and concave convex, etc.) Influence of processing deformation such as deformation occurring at the time of drilling or laser processing or shear melting cannot be avoided.

That is, a plurality of circular plates attached to the unevenness for forming the surface of the two rollers to be engaged cannot be engaged unless they are configured with the same thickness in the roller axial direction, that is, the difference in the thickness of the plurality of circular plates attached to the unevenness If it does not mesh well. Even when the meshing is poor, it may be difficult to rotate both rollers together.

For this reason, when assembling the uneven | corrugated provision apparatus of the said application, you must process and adjust one by one so that thickness may enter into a fixed value every number. For this reason, trouble has arisen in manufacturing an uneven | corrugated provision apparatus cheaply.

Moreover, regarding the unevenness | corrugation provided by the unevenness | corrugation provision apparatus, there are many cases where it is not necessary to be uneven | corrugated superior in the aesthetic sense by which unevenness | corrugation was unified by appearance depending on a use.

In addition, since the unevenness applying device according to the above application forms a roller by stacking only a plurality of circular plates with unevenness, the convex portion 21 for preventing the engagement failure may not be sharp, for example, the square head. There is no case (Fig. 9). Moreover, since only the circular plate with concavities and convexities has conventionally had to overlap, it becomes a cause which makes the weight of the roller itself heavy as a result.

Moreover, in the case of a thin sheet-like thing, the uneven | corrugated sheet-like thing may be wound around a roller by the shape. In order to prevent this, many needle-shaped rods are provided in the vicinity of the engagement position of the roller. However, in the concave-convex imparting device according to the above application, since only a plurality of circular plates with concave-convex and concave-convexities overlap, there is a limit to bringing the tip of the needle-shaped bar closer to the surface of the roller.

It is a figure which shows the state of the round plate convex part with the unevenness | corrugation which raised the workability in the plate | board thickness direction.

The present invention has been considered on the basis of the above circumstances. And it aims at the next thing. It is to provide a means for easily correcting variations in thickness due to tolerances of the plate thickness itself of the round plate with irregularities and deformation during irregularities processing. Moreover, it is providing the unevenness | corrugation provision apparatus which can freely adjust the processing degree of unevenness | corrugation as needed. Moreover, it is providing the unevenness | corrugation provision apparatus which is much lighter.

The object of the present invention is achieved by providing an apparatus having the following features. It is an apparatus characterized by having a space | interval maintenance mechanism in the round plate with an unevenness | corrugation, or between a round plate with an unevenness | corrugation.

As the gap maintaining mechanism, a wheel-shaped gap holding plate (hereinafter referred to as a "spacer") is generally used. In the case of a material which can be integrally molded, for example, a synthetic resin material, the circular plate with irregularities and the spacer plate may be integrally formed.

Hereinafter, the case where a spacer is used as a space maintenance mechanism is described. In addition, in the invention according to claim 1, the apparatus according to the present invention achieves the object more effectively by applying the following configuration. On one roller rotatably attached, the opposing roller is pressed by its own weight or pressing mechanism. The unevenness of one roller and the unevenness of the opposite roller are engaged with each other. By rotating one roller it is possible to rotate the counter roller.

EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of this invention is described concretely according to an accompanying drawing.

4 is a schematic diagram showing a state of use of the unevenness providing device.

In this embodiment, the sheet-like article 6 passes between one roller 1 and the counter roller 2. In the meantime, unevenness | corrugation is given to the sheet-form by the uneven | corrugated shape 5 of the surface of a roller.

1 to 3 show an embodiment of the invention corresponding to claim 1 of the present invention.

FIG. 2 shows the concave-convex circular plate 20, FIG. 3 shows the spacer 28, and FIG. 1 shows the rollers 1 and 2 assembled therewith.

The thickness of the round plate with concavities and convexities is determined by the size of the concavities and convexities required and the thickness or shape of the sheet-like object to be concave and convex. Generally, about 1 mm to 3 mm is used.

The protrusion 26 is provided in the inner diameter side of the circular plate with an unevenness | corrugation. This protrusion is fitted in the key groove 27 provided in the roller shaft 23 so that the position of the unevenness | corrugation of a round plate with an unevenness | corrugation may not shift.

Moreover, the number of protrusions may be single or may be provided more than one.

Moreover, the pitch of the unevenness | corrugation of a circular plate can be shifted | suitably suitably by designing the position of a projection suitably, and / or fitting one type of circular plate with an unevenness | corrugation alternately in front and back. As the material of the concave-convex circular plate 20, metal materials such as steel, aluminum, stainless steel, titanium, and copper, and other nonmetal materials such as hard resins and rubber are also used.

In FIG. 7, the case where the side part of the convex part of one roller 1 and the side part of the convex part of the opposing roller 2 are in adjoining relationship is shown. In this case, the shear effect (cut effect) can be exerted on the sheet-like object between the convex portions of both rollers. The thickness of the spacer 28 may be determined in consideration of the shear effect and the uneven shape of the round plate with unevenness. Normally used spacers have a thickness of 0.5 mm to 2 mm.

The outer diameter of the spacer is generally the same as or smaller than the diameter forming the concave portion of the round plate with irregularities in consideration of the thickness, shape, and the like of the sheet-like article 6. When the processing accuracy of each component is good and the shearing effect described above is effective, the outer diameter of the spacer may be larger than the diameter forming the concave portion of the round plate with irregularities in consideration of the thickness, shape, etc. of the sheet-like article 6. It may be.

The inner diameter of the spacer is determined in consideration of the tolerance on the basis of the diameter of the roller shaft.

As the material of the spacer, one having the same material as that of the round plate 20 with unevenness can be adopted. By using a hard nonmetallic material, it is possible to produce a lightweight and inexpensive.

The rollers 1 and 2 are assembled as follows. As shown in FIG. 1, the fixing wheel 25 and the contact plate 24 are fitted to the start end of the roller shaft 23. At the end of the roller shaft 23, the contact plate and the fixed plate are fitted in the same manner as the start end.

Between the fixed wheel 25 and the contact plate 24 at the beginning and end of the roller shaft 23, the round plate 20 with the unevenness, the spacer 28, the round plate with the unevenness, and the spacer are in this order. The roller roller 23 is fitted to the roller roller shaft 23, and is gripped and fixed by the fixing wheel 25 and the contact plate 24 at the beginning of the roller shaft 23.

Moreover, you may employ | adopt a bolt and a nut mechanism instead of the fixed wheel.

The length of the concave-convex portion of the roller is determined in consideration of the processing width of the concave-convex sheet-like article 6, the price of the apparatus, and the like. For example, the length of the concave-convex portion of the roller is about 150 mm in a small apparatus for home use and about 300 mm in a commercial apparatus.

In addition, the roller shaft diameter is determined in consideration of the length of the uneven portion of the roller and the shape of the uneven processed sheet-like article 6. For example, the roller shaft diameter is about 20 mm for small devices for home use and 36 mm for devices for businesses.

Of course, the length of a concave-convex part of a roller, and a roller shaft diameter can also manufacture a smaller or larger dimension as needed.

7 is a view of the concave portion at the top of the convex portion 21 of the concave-convex round plate. For ease of understanding, the convex portion is shown by a thick solid line, the concave portion is shown by a broken line, and the circular plate with irregularities is drawn with a half pitch shift. The cross section cut | disconnected in the roller axial direction was seen from the A arrow direction, and the engagement state of both rollers was shown.

The effect that can be expected in that case is as described above.

Regarding the shape of the convex portion of the round plate with irregularities, as shown in FIG. 8, a taper narrowing in the plate thickness direction toward the outer circumference of the round plate may be taken. The taper may be different on both sides of the plate. By taking this taper, the engagement of both rollers can be made easy.

As for the shape of the convex portion of the round plate with concave-convex, as shown in Fig. 9, if the shape having the pointed square head portion as a basic shape is obtained, Fig. 10 is obtained when the thickness in the circumferential direction of the tip of the convex portion is made thin. Moreover, when the thickness of the convex part front end is made thin, the shape shown to FIG. 11, FIG. 8 is obtained.

Of course, the thickness of the circumferential direction of the front-end | tip of a convex part can also be made thin using the board thickness itself, without making it thin in the board thickness direction. In that case, the shape shown in FIG. 7 is also obtained.

The convex shape of which the square head is pointed is larger than the convex shape of which the square is sharp, and the surface area of the bottom rectangular part having the sharp square is the same, and a circular plate of the same diameter can form a large surface area by the sheet-like object. This has the advantage of providing a larger adsorption effect to the uneven workpiece.

Moreover, you may make the roller 1 and the roller 2 mesh with the circumferential length of a convex part and a recessed part as another thing.

In addition, B sectional drawing in FIG. 10, and C sectional drawing in FIG. 11 are sectional drawing centered on the plate thickness center of the round plate with an unevenness | corrugation. In the above sectional view, in order to make it easier to understand the shape of the unevenness, the circular portion of the circular plate is drawn in a straight line shape.

5 and 6 show an embodiment of the invention corresponding to claim 2 of the present invention.

5 is a sectional view when the apparatus is viewed from the front, and FIG. 6 is a side view.

The side wall block consists of a pair of side pillars 11 and a top plate 15. The side wall block is fixed to the base plate 14 by a pair of left and right screws and the like. Inside the side wall block, a lower piece 16 is provided. Moreover, the lower bearing stand 12 and the upper bearing stand 13 are slidably fitted between the side pillars on the upper side thereof.

The roller 1 is attached to the left and right pairs of lower bearing posts through the bearings. Moreover, the roller 2 is attached to a pair of left and right upper bearing stands through a bearing. The pressing mechanism consists of a screw 17 screwed to the top plate 15 and a gap adjusting knob 18. By pressing the upper bearing stage downward by the pressing mechanism, the gap between the rollers can be freely adjusted in accordance with the thickness or shape of the sheet-like article.

When the manual handle 19 is rotated, the roller 1 and the roller 2 rotate to impart unevenness to the sheet-like object.

Further, a coil spring may be interposed between the upper end of the bearing stand and the lower end of the screw.

If the sheet-like article is thin, irregularities can be provided only by the weight of the roller 2.

The present invention is implemented in the form described above, and has a possibility of remarkable industrial use as described below by providing a spacer.

By providing the spacer, it is possible to easily handle the influence of the tolerance of the thickness of the circular plate and the processing deformation such as deformation and shear dissolution occurring during the uneven manufacturing process, for example, during drilling and laser processing.

For example, the barrel processing for removing the deformation generated at the time of drilling is unnecessary.

As the shape of the spacer, a wheel-shaped simple structure can be adopted. Such a spacer does not need to provide a mechanism for preventing idling such as protrusions provided in the inner diameter portion of the round plate with irregularities. As a result, the spacer can be manufactured easily and inexpensively.

In addition, when a plurality of spacers having different thicknesses are prepared with such a spacer, it is very easy to make the blocks of the circular plate with concave-convex parts consisting of a plurality of sheets with the same thickness. In this way, by further stacking and overlapping the blocks of the circular plate with concave-convex, which is composed of a plurality of sheets divided by blocks, it is possible to easily assemble a long roller having a good positional accuracy.

Moreover, by making the outer diameter of a spacer smaller than the diameter of the circle which comprises the bottom part of the recessed part of a circular plate with an unevenness | corrugation, it can prevent that it is influenced by the processing deformation of an uneven | corrugated part, for example, a deformation | transformation of a perforation, or the shear dissolution of laser processing.

From the above various effects, it is not necessary to adjust and process the circular plate with concavo-convex shape of a complicated shape, and the apparatus can be provided at low cost.

Since the conventional uneven | corrugated provision apparatus forms a roller by overlapping only a plurality of circular plates, the convex part for preventing an engagement failure may have to be pointed sharply, for example, a square head part. In addition, even when solving the lightweight and inexpensive spacing mechanism according to the present invention, since only the circular plate with concave-convex protrusions can be overlapped, conventionally, the weight of the roller itself is heavy, and the apparatus is expensive. It was a cause.

In the present invention, by providing the spacers, the unnecessary processing as described above can be omitted, and a lightweight spacer can be employed instead, so that the overall weight of the apparatus can be reduced and the cost can be reduced.

When the side part of the convex part of one roller 1 and the side part of the convex part of the opposing roller 2 are adjacent, the shear effect (cutting effect) can be exerted on the sheet-like object between these convex parts of these rollers. . For this reason, a shear effect can be made strong by making thickness of a spacer small, and the open hole can also be formed in a sheet-like object in this part. As a result, the sheet-like article of paper can have a larger adsorption performance. It is possible to further widen the use of sheet-like articles of paper as sorbent papers such as oil.

Although a thin sheet-like object may be wound on a roller after uneven processing, by installing a number of needle-shaped rods near the spacer to prevent this, it is possible to reliably prevent the coiling of the sheet-like object without causing any rotational disturbance of the roller. have.

In addition, in the case of a material having an air core such as a single ball material, the irregularities of both rollers do not necessarily need to be engaged, and adsorptivity can be enhanced simply by providing a hole opened in the convex portion.
