DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an unevenness imparting device for imparting irregularities to a sheet-like material such as paper, synthetic resin film, synthetic resin paper, synthetic resin plate, metal sheet, food processed product, and the like. Regarding the product.

[0002]

2. Description of the Related Art A sheet-shaped article having irregularities has been used as a decorative material having excellent decorativeness, and as a wiping paper because of its improved wiping effect. However, those with irregularities on the sheet-like object,
It is not limited to the above-mentioned applications, but is used as a polished paper utilizing the protrusions and recesses of the irregularities. It can be used as a packing material as a packing material by utilizing the cushioning properties of the unevenness.

[0003] However, the process of providing unevenness is carried out on a large scale and industrially using a dedicated manufacturing apparatus. In this case, a material such as a pattern paper, a synthetic resin film, a synthetic resin paper, or a synthetic resin is used. It is difficult to use resin paper and aluminum foil as decorative paper with irregularities easily by using irregularities, and it is also difficult to easily use used paper and waste paper, such as newspaper paper and copied paper, It is difficult to provide irregularities easily by using the above method and to use it as an adsorbent paper / polishing paper at low cost for daily use.

In order to cope with such a problem, a roller is formed by stacking a large number of circular plates having irregularities on the outer periphery, the two rollers are engaged with each other, and a sheet is passed between the rollers. As for an apparatus for imparting irregularities to a substrate, Japanese Patent Application No. 10-3 by one of the inventor and applicant has disclosed.
76698 (hereinafter referred to as "the application").

The concavo-convex imparting device according to the application can impart concavities and convexities excellent in appearance and uniformity to the sheet-like material. ) To form a roller
Inevitably, the influence of processing tolerances such as burrs, burrs, warpage, etc., which occur during the manufacturing process of unevenness, for example, at the time of punching or laser processing, is required. That is, unless the circular plates with irregularities forming the surfaces of the two rollers to be meshed with each other are formed to have the same thickness in the axial direction of the rollers, they will not mesh with each other, and the circular plates with irregularities will be meshed.
If the thicknesses are different, the engagement does not work well, and even if the engagement is a little poor, it may be difficult even to rotate both rollers in conjunction. For this reason, when assembling the concavo-convex imparting device of the present application, it is necessary to process and adjust each time so that the thickness is kept at a constant value every several sheets, which hinders inexpensive manufacturing of the concavo-convex imparting device. ing.

[0006] Further, in the unevenness applying device according to the application, since a roller is formed by stacking a large number of circular plates with unevenness, the convex portion (21) is sharpened in order to prevent poor meshing.
For example, there is a case where it is necessary to form a mounting pyramid (FIG. 9), and even if a lightweight and inexpensive spacing mechanism is provided, a circular plate with concavities and convexities must be provided, and as a result, the weight of the roller itself And makes the device expensive.

Further, in the case of a thin sheet-like material, a sheet-like material having an uneven surface (hereinafter referred to as an "irregularly processed object") may be wound around a roller depending on the properties thereof. The rod is provided near the meshing point of the rollers, but the unevenness providing device according to the application overlaps only a large number of circular plates with unevenness so that the unevenness is densely packed, so there is a limit to bringing the tip of the needle-shaped bar close to the roller surface. there were.

Further, since the unevenness is monotonous, it is not possible to create a complicated appearance pattern or a predetermined pattern.

Furthermore, when using a processed material as a cushioning material for packing, since only a single height of unevenness has a single cushioning property and a small amount of cushioning, packaging materials such as fruits and vegetables and heavy small machine parts are used. As a packaging material for wrapping them one by one, there was a tendency to lack cushioning properties.

[0010] In addition, although a fixed-size material is used as a processing material, it has been desired that the processing width of the concavo-convex processed material be a fixed size.

[0011] Further, in order to enhance the cushioning property and to facilitate the cutting during use, it has been demanded to actively cut a part of the workpiece.

When the irregularities are small and the number of irregularities is large, one step of processing accuracy is required in order to engage the irregularities on one roller surface with the irregularities on the opposing roller surface.

Further, the workpiece may be curved depending on the shape of the unevenness, the diameter of the roller, the properties of the sheet, and the like.
Correction after unevenness processing often impaired the unevenness.

In addition, in the case of a sheet made of a resin material (when a part of the sheet contains a resin material, it also includes, for example, a coating process; hereinafter, referred to as a “resin sheet”).
Is inferior in molding processability to paper due to a high flexural modulus and the like peculiar to the resin, and there is a case where sufficient unevenness cannot be formed only by simple unevenness processing. In addition, in the case of performing unevenness processing on a food material whose workability is improved by heating to an appropriate temperature, it is necessary to separately heat the material to an appropriate temperature before the unevenness processing.

Conventionally, metal sheets, wire mesh, cardboard,
No products have been found that provide irregularities to synthetic resins, nonwoven fabrics, synthetic resin films, synthetic resin papers, and synthetic resin plates, and actively utilize the unique effects of the irregularities imparted to these materials.

[0016]

A second object of the present invention is to make it possible to produce various uneven patterns and predetermined patterns, and to manufacture a processed article having better cushioning properties.

A third object of the present invention is to provide an unevenness providing device which can make a cut or cut into a fixed width simultaneously with the unevenness processing.

A fourth object is to make the unevenness providing device lightweight and inexpensive.

A fifth object of the present invention is to make it possible to produce an uneven workpiece having a high flatness by preventing the workpiece from bending.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings.

FIG. 4 is a schematic diagram showing the usage of the unevenness providing device. The sheet-like material (6) is passed between one roller (1) and the opposing roller (2), and the unevenness is imparted to the sheet-like material by an uneven pattern (5) on the roller surface.

FIGS. 1 to 3 show an embodiment of the present invention corresponding to claim 1 of the present invention. FIG. 2 shows a circular plate with irregularities (20), FIG. 3 shows a spacer (28), and FIG. 1 shows rollers (1, 2) assembled therewith.

The thickness of the concavo-convex circular plate (20) depends on the required size of the concavo-convex and the thickness of the sheet-like material to be processed.
Depends on properties, but generally 1mm to 3m
m is used. A projection (26) is provided on the inner diameter side of the circular plate with irregularities, and the projection is fitted into a key groove (27) provided on the roller shaft (23), so that the position of the irregularities on the circular plate with irregularities is shifted. I do not have it. The projection may be provided singly or plurally. In addition, by appropriately designing the positions of the projections, one type of circular plate with projections and depressions can be fitted alternately on the front and back sides, so that the pitch of the projections and depressions of the circular plate can be appropriately shifted. For round plates with irregularities, steel
In addition to metal materials such as aluminum, stainless steel, titanium and copper,
Non-metallic materials such as hard resin and rubber are also used.

By appropriately shifting the position of the projection (26) of the concavo-convex circular plate, the position of the projection (21) can be shifted, and a random pattern or a wavy pattern can be created. Further, instead of the projection / key groove (27) structure, the roller shaft (23) may have an elliptical structure having a partially straight line from a circle. Furthermore, it is also possible to change the outer diameter of the circular plate with irregularities so that the outer diameter of one roller and that of the opposing roller are different (FIG. 18).

FIG. 7 shows a projection (2) of one roller (1).
The case where the side portion of 1) and the side portion of the convex portion (21) of the opposing roller (2) are adjacent to each other is shown. In this case, the sheet-like material (6) is provided between the convex portions of both rollers. Since the shearing effect (the effect of scissors) can be exerted on the spacer (28), the thickness of the spacer (28) can also be determined in consideration of the shearing effect and the uneven shape of the circular plate (20) with unevenness.
The thickness of the spacer usually used is 0.5mm to 2m
m. As the material of the spacer, the same material as that of the circular plate with unevenness can be adopted. However, if a hard non-metallic material is used, the spacer can be manufactured lightweight and inexpensively. The outer diameter of the spacer is determined by considering the thickness and properties of the sheet-like material, and in order to make the above-mentioned shearing effect effective when the processing accuracy of each component is good, the concave portion of the concavo-convex circular plate is used. Although the diameter may be larger than the diameter to be formed, it is generally preferable that the diameter is equal to or smaller than the diameter to form the concave portion of the concave and convex circular plate. The inner diameter is determined in consideration of a tolerance on the basis of the diameter of the roller shaft.

The thickness of the spacer (28) may be provided on the uneven circular plate (20), and the function of the spacer may be imparted to the uneven circular plate.

The length of the uneven portion of the rollers (1, 2) is as follows:
It is determined in consideration of the processing width of the sheet-shaped material (6) to be processed to be uneven and the price of the device.
mm, and about 300 mm for corporate equipment. In addition, the roller shaft diameter is determined in consideration of the length of the uneven portion of the roller and the properties of the sheet-like material to be unevenly processed,
The size is about 20 mm for a small household apparatus, and about 36 mm for a corporate apparatus. Of course, the length of the uneven portion of the roller and the roller shaft diameter can be made smaller or larger as needed.

As shown in FIG. 1, the rollers (1, 2) are fitted with a retaining ring (2) fitted at the starting end of the roller shaft (23).
5), a circular plate with irregularities (2
0), a spacer (28), a circular plate with concavities and convexities, and a spacer are fitted in this order, and the end is also gripped and fixed with a backing plate and a stopper plate in the same manner as the start end. Note that a bolt / nut mechanism may be employed instead of the retaining ring.

In assembling, a plurality of circular plates with irregularities (20) can be stacked to form a group of circular plates with irregularities. Similarly, a plurality of spacers (28) can also be stacked and used. (Figure 15).

FIGS. 5 and 6 show an eleventh embodiment of the present invention.
1 shows an embodiment of the invention corresponding to FIG. FIG. 5 is a sectional view when the apparatus is viewed from the front, and FIG. 6 is a side view. Base plate (1
4), a side wall block composed of a pair of side pillars (11) and an upper plate (15) is fixed by a pair of left and right screws. A lower piece (16) is provided in the side wall block, and a lower bearing stand (12) and an upper bearing stand (13) are further provided thereon.
Are slidably fitted between the side columns. A roller (1) is mounted on a pair of left and right lower bearing stands via a bearing, a roller (2) is mounted on a pair of left and right upper bearing stands via a bearing, and the upper bearing stand is an upper plate (15).
The gap between the rollers can be freely adjusted according to the thickness and properties of the sheet-like material by being pressed downward by a pressing mechanism including a screw (17) screwed into the sheet and a gap adjusting knob (18). . When the manual handle (19) is turned, the roller (1) and the roller (2) rotate, and irregularities are imparted to the sheet. Note that a coil spring may be interposed between the upper end of the upper bearing stand and the lower end of the screw. When the sheet is thin, the unevenness can be provided only by the weight of the roller (2). In addition, a power source such as a motor can be used as a rotation drive source of the roller.

FIG. 7 is a diagram showing the concave portion from the top of the convex portion (21) of the circular plate with concave and convex portions. For easy understanding, the convex portion is shown by a thick solid line and the concave portion is shown by a broken line. Is shifted by a half pitch. In addition, the cross section cut in the roller axis direction is viewed from the direction of the arrow A, and the engagement state of both rollers is also shown.

The shape of the convex portion (21) of the circular plate with irregularities is as follows.
As shown in FIG. 8, a taper may be formed in the thickness direction toward the outer periphery of the circular plate, and the taper may be different on both surfaces of the plate. By taking this taper, the engagement of both rollers can be facilitated.

The shape of the convex portion (21) of the circular plate with irregularities is as follows.
When the thickness of the tip of the convex portion in the circumferential direction is reduced using the mounting quadrangular pyramid shape as shown in FIG. 9 as a basic shape, FIG. 10 is obtained.
When the thickness of the tip of the projection is reduced in the thickness direction, the shapes shown in FIGS. 11 and 8 are obtained. Of course, the thickness in the circumferential direction of the tip of the convex portion can be reduced, and in this case, the shape shown in FIG. 7 can be obtained. The convex shape of the mounting pyramid has a larger surface area than the convex shape of the quadrangular pyramid, as long as the area of the bottom rectangular portion is the same and the height of the protrusion (21) is the same. It has the advantage that it can be formed, and a greater adsorption effect can be imparted to the uneven workpiece. Alternatively, the roller (1) and the roller (2) may be engaged with each other by making the circumferential lengths of the convex portion and the concave portion different. In addition, the B section in FIG.
11 and the cross section C in FIG. 11 (viewed in the direction of arrow C), the cross section at the center of the thickness of the circular plate with concavities and convexities is drawn in such a manner that the circular portion of the circular plate is straight to facilitate understanding of the shape of the concavities and convexities. Things.

FIG. 12 shows an example of a circular plate with concavities and convexities in which a pair of concavities and convexities is composed of two or more types of concavities and convexities. FIG.
Fig. 1 shows an example in which a concave portion is provided in the head of a mounting quadrangular pyramid.
Reference numeral 2b denotes a configuration in which a convex portion is provided on the head of the mounting quadrangular pyramid.
The use of a circular plate with concavities and convexities having two or more kinds of concavities and convexities makes it possible to create a concavo-convex pattern having a different aesthetic appearance and a good cushioning property.

The concavity and convexity of the concavo-convex circular plate need not be one kind of concavity and convexity, but may be a combination of two or more kinds of concavities and convexities as shown in FIG. Further, in one roller, a circular plate with irregularities having different irregularities can be mixed, and the thickness of the circular plate with irregularities can be changed.

The formation of the predetermined pattern on the uneven workpiece can be performed by thinning out a predetermined portion of the unevenness of the circular plate with unevenness (20) to create an unpatterned portion in the uneven pattern, or by forming the unevenness of the circular plate. It is possible to make the predetermined unevenness of a predetermined portion of the above-mentioned portion different from that of the other portion. Further, even in the case of a circular plate with irregularities composed of two or more types of irregularities, it is possible to mix circular plates with irregularities composed of different irregularities.

FIG. 13 illustrates a case where a part of the spacing mechanism also functions as a cutting mechanism. Circular plate with cutting blade (3
0) is an example in which a circular plate with a cutting blade having a diameter larger than the outer diameter of the circular plate with irregularities is sandwiched between the circular plate with irregularities (20) and the spacer (28). )
Is an example in which a circular plate with a cutting blade having a diameter larger than the intermediate diameter of the irregularities of the circular plate with irregularities is sandwiched between the circular plate with irregularities and the spacer. This is an example in which a circular plate with a cutting blade having a diameter larger than the outer diameter of the circular plate with irregularities is sandwiched between the circular plates.

When a part of the interval maintaining mechanism also serves as a cutting mechanism, a sheet blade is partially cut by providing cutting blades partially in the circumferential direction as shown in FIG. be able to. The number of cutting blades may be singular or plural, and the length and interval of the blades can be arbitrarily set, and the entire circumference can be arbitrarily mixed with the interval holding mechanism of the cutting mechanism.

Particularly, in an unevenness providing device which requires a large number of small unevennesses, one of the two rollers is made of an elastic material capable of responding to the protrusion (21) of the roller having unevenness, for example, an elastic body. The roller surface can be formed of rubber or urethane (not shown), and in this case, the manufacturing cost can be reduced.

Depending on the properties of the sheet-like object (6), the sheet-like workpiece may be curved, resulting in a reduction in commercial value. The twelfth aspect of the present invention is provided with a mechanism for preventing the bending, and an example is shown in FIG. The method shown in FIG. 18A is a method in which the sheet-like supply table (140) is inclined by the supply table angle (142) with respect to the contact surface of both rollers, and the sheet-like substance is constrained at the time of uneven processing to form a sheet-like substance. This is to provide a curvature in the opposite direction to offset the curvature caused by the unevenness processing. In the method shown in FIG. 18b, a guide rod (141) is provided near the roller in addition to the supply table, and a roller or a simple round bar is used as the guide rod. It is desirable that the angle of the supply table and the mounting position of the guide rod can be changed in consideration of the properties and shape of the sheet-like material (not shown). Also, in the illustrated example, the bending prevention mechanism is provided on the supply side of the sheet-like material.
It may be provided on the side opposite to the supply side.

FIG. 14 shows an example of a mechanism for heating a roller in which a heating element is incorporated in a roller shaft. The core of the roller shaft (23) is pierced, and a heating element (43), for example, a nichrome wire is embedded in the pierced portion, and the heating element is connected to a slip ring (42) provided on an electric insulator (41). I do. On the other hand, electric power is sent from the slip ring brush (44) to the heating element via the slip ring to generate heat, and the concavo-convex circular plate (20) is heated from the shaft core side, and heat is applied to the resin sheet having heat deformability during the concavo-convex processing. In addition, the material is softened to promote thermal deformation and to form sufficient irregularities. A sufficient electrical insulation treatment is performed between the heating element and the roller shaft using a material having good electrical insulation and good heat resistance, such as ceramic fiber, blanket, silicon carbide, and silica. As other heating mechanisms, there are a non-rotating fixed mechanism in which a heating element is simply inserted through the roller shaft through the roller shaft, and a mechanism in which heating is performed from outside the roller.

Examples of the method used for the temperature detecting mechanism include a method in which a non-contact temperature measuring device is provided outside the roller, and a method in which a thermocouple or the like is provided through the roller shaft as in the case of the above-described heating element. There is.

The temperature control device may be any device that can compare the preset temperature with the temperature detected by the temperature detecting mechanism and supply a heat source necessary for controlling the temperature of the heating element.

When a metal sheet, such as a steel sheet, an aluminum sheet, a stainless steel sheet, a titanium sheet, and a copper sheet, is provided with irregularities, it depends on the type of metal, but has a thickness of about 0 to about daily use. .1mm (stainless steel thin plate)
When the thickness is about 4 mm (aluminum thin plate), it is possible to perform uneven processing with the above-mentioned roll. The metal sheet with unevenness can be used as a decorative material due to its glossiness change, and it can be used as a structural material alone or pasted with other materials due to the effect of improving bending rigidity due to unevenness processing As a backing material, for example, a building material and an industrial material to which a sound absorbing material, a heat insulating material, and a heat insulating material are attached, and as a composite building material that is composited with another material, such as a sponge such as rubber or urethane foam.
It has a wide range of uses. Furthermore, since the diffuse reflection of sound and light is improved, the material of the sound / light reflector, building materials,
It can be used effectively as an industrial material. Also,
Because the surface area increases and the turbulence of the heat medium is promoted,
It can also be used as a heat dissipating material.

In the case where a wire mesh made of a metal wire, for example, a steel wire, an aluminum wire, a stainless steel wire, a copper wire, or the like, is provided with irregularities, due to the properties of the wire mesh, less labor and power are required as compared to the above-described thin metal plate. Can be used for uneven processing. However, in the case where the wire mesh is provided with irregularities, one having a large protrusion (21) is used. Due to the increase in surface area, the increase in rigidity, and the unevenness of the wire mesh itself, the wire mesh with irregularities is more suitable as a material for rigid and porous filters. Applications, for example, as a sound absorbing material, a heat insulating material, and a holding material for a heat insulating material are further opened.

In the case where the corrugated cardboard is provided with irregularities, the corrugated cardboard has a large amount of irregularities (21) because the core paper is interposed therebetween, but the corrugated cardboard can be processed with a small amount of labor and power. . Corrugated cardboard is used in various fields as a packing box, but on the other hand, the rigidity and porosity of the cardboard itself is high, so it is difficult to reduce the amount at the time of bulk disposal, so it is more difficult to discard than ordinary paper products It has a drawback. However, the corrugated cardboard material itself has a higher fiber content than gravure paper or the like, and is easily recyclable for other uses. In particular, when making fertilizers using familiar waste such as fallen leaves and household waste, corrugated cardboard with unevenness has a moderate permeability depending on the size and depth of the unevenness, the opening ratio of the raised part, etc. Fertilizer has the effect of promoting the conversion of waste such as fallen leaves and household waste into fertilizer because of its permeability and water retention, and the ease of blocking fertilizer from the flatness, rigidity and integrity of corrugated cardboard. It has various effects such as an improvement in handleability as a function. Therefore, the active use of corrugated cardboard with irregularities as one material for producing fertilizer is effective for treating cardboard that is bulky and troublesome, and contributes to the preservation of the global environment. There is something. Furthermore, by utilizing the intricate surface effect of the corrugated cardboard and the irregularity processing, it is used as the core material of FRP to reduce FR
It becomes possible to produce an inexpensive product in which the amount of FRP used in the P product is reduced.

When a synthetic resin plate is produced from a synthetic resin as a raw material, if the raw material is supplied to a smooth roller, the raw material cannot be appropriately supplied, and it may be difficult to produce the synthetic resin plate. In such a case, when the raw material is passed through a concavo-convex imparting device that imparts concavities and convexities with a roller, the raw material can be accurately supplied by the concavo-convexity of the roller, and the concavo-convex shape suitable for the next process of producing a smooth synthetic resin plate can be obtained. We can supply semi-finished products with good quality. The production process may be completed in this step to obtain a finished synthetic resin plate having irregularities.

When unevenness is imparted to a non-woven fabric containing a thermosetting thermoplastic fiber or a thermosetting thermoplastic adhesive and having a thermosetting thermoplastic property by a concavo-convex imparting device provided with a mechanism for heating a roller, The nonwoven fabric exhibits thermosetting properties and thermoplasticity as a whole, and the unevenness is hard to be worn out. Therefore, when used as an underlaying material for foods, etc., the drainage property is improved, and the preservability of the foods is enhanced, and the abrasive material is used. As a result, the abrasiveness is improved, and the nonwoven fabric can be used more times.

When unevenness is applied to a thermosetting / thermoplastic synthetic resin film / synthetic resin paper / synthetic resin plate by a concavo-convex imparting device equipped with a mechanism for heating a roller, there is no jaggedness and uneven surface during the concavo-convex processing. It can form smooth irregularities,
Further, in the case of a synthetic resin plate, cracks, which are likely to occur, can be prevented, so that applications similar to those of the above-mentioned metal thin plate are opened.

[0068]

The present invention is embodied in the form described above, and has remarkable effects as described below.

By providing the spacer, the effect of the processing tolerance such as burrs, burrs, warpage, etc., which occurs during the manufacturing process of irregularities, for example, at the time of punching or laser processing, can be easily obtained. Processing. For example, barrel processing for removing burrs generated at the time of punching processing becomes unnecessary.

As for the shape of the spacer, there is no need to provide a mechanism for preventing idling like a protrusion provided on the inner surface of the circular plate with projections and depressions. Therefore, an inexpensive one can be adopted.

If several spacers having different thicknesses are prepared with spacers having such a shape, it becomes extremely easy to make a plurality of blocks of a circular plate with irregularities of the same thickness. By further stacking a plurality of blocks of the circular plate with irregularities, which are divided into blocks as described above, it is possible to easily assemble a long roller with good positional accuracy of the irregularities.

Further, by making the outer diameter of the spacer smaller than the diameter of the circle forming the concave bottom of the concave and convex circular plate, the processing distortion of the concave and convex portion, for example, the burr of punching.
Laser processing can eliminate the effects of shearing. From the above effects, there is no need to process and adjust the circular plate with the irregularities having a complicated shape, and the apparatus can be provided at low cost.

In the conventional concavo-convex imparting device, since a roller is formed by stacking a large number of circular plates only, in order to prevent poor meshing, it is necessary to sharpen the protruding portion, for example, to make the mounting a quadrangular pyramid. Yes, even if a lightweight and inexpensive spacing mechanism is needed, a round plate with concavities and convexities must be provided, which has contributed to increasing the weight of the roller itself and making the device expensive. By providing a spacer, unnecessary processing as described above can be omitted,
Since a lightweight spacer can be used instead,
It has become possible to reduce the weight and cost of the entire device.

When the side of the protrusion of one roller (1) and the side of the protrusion of the opposing roller (2) are adjacent to each other, a shearing effect is exerted on the sheet between the protrusions of both rollers. Since the effect of the scissors can be exerted, the shearing effect can be strongly exerted by reducing the thickness of the spacer, and an opening can be formed in the sheet at this portion. As a result, the sheet-like material of paper can have greater adsorption performance, and it is possible to further expand its use as an adsorption paper for oil and the like.

There is a case where a thin sheet-like material is wound around the roller after the unevenness processing. By providing a plurality of needle-like bars on the spacer portion to prevent this, the rotation of the roller is not hindered. The winding of the sheet can be reliably prevented.

In the case of a material having an air core, such as a corrugated cardboard material, it is not always necessary to engage the irregularities of both rollers, and the adsorbability can be improved by merely providing an opening with a convex portion.

In addition, one or more circular plates with irregularities and one or more spacers are mixed together, or a circular plate is formed from two or more types of irregularities, or a circular plate with different irregularities is mixed. By doing so, it is possible to create a complex pattern with various and beautiful appearances, so that the aesthetic value of the textured paper can be enhanced.

Further, two pairs of projections and depressions of the circular plate with projections and depressions
The following various effects can be exhibited by mixing irregularities composed of more than two kinds of irregularities. The first effect is
Since the cushioning property differs depending on the size and shape of the unevenness, it is possible to manufacture an excellent cushioning material having different cushioning hardness and softness by mixing the unevenness having the different size and shape of the unevenness. The second effect is that by adopting a large unevenness in one of the two or more kinds of unevenness, it becomes possible to overlap a plurality of materials to provide the unevenness,
As a result, it has become possible to create a concavo-convex workpiece that cannot be easily separated by integrating a plurality of sheets. According to the second effect, the packing buffer that increases the commercial value of the product is obtained by using the paper on which the items related to the product such as the product name, the production area, and the trademark are printed on one of the surfaces of the plurality of processed papers. Material can be processed at low cost. The third effect is that, by adopting a large unevenness in one of the two or more kinds of unevenness, it becomes possible to obtain a packing material having better flexibility than a packing material having only one kind of unevenness. In addition to the effect of item 1, it is possible to pack fruits and vegetables, heavy small machine parts, and the like one by one at a low cost as a packing material having good cushioning properties.
The fourth effect is that by adopting unevenness different in size,
That is, it is possible to further reduce the flat portion of the unevenly processed product, further increase the surface area, and enhance the unevenness processability such as further pulverizing a filler constituting the paper, for example, calcium carbonate or a pigment. This effect makes it difficult to read the characters printed on the textured paper, so it is possible to reuse waste paper that had been cut off with slitters and discarded as waste as useful packing cushioning material In addition, the improved adsorptivity makes it possible to use waste paper and the like as adsorptive paper having better adsorptivity, and furthermore, the separation properties of the fibers constituting the paper in water (water disaggregation). ), It has become easier to reuse the fibers of the used paper.

In addition, a predetermined portion of the irregularities of the circular plate with irregularities may be thinned out, or the predetermined irregularities of the predetermined portion of the irregularities may be different from the other irregularities. Since the part can have a function of creating a predetermined pattern, it is possible to increase the commercial value of the packaged product by giving a unique pattern or trademark to the product.

As a result of using the cutting mechanism as a part of the interval holding mechanism, it becomes possible to process a concavo-convex workpiece with a fixed width, which is suitable for the size of the packing material and the size of the packing box. It is now possible to supply cushioning material for underlays, insoles, and overlays. In addition, the spacing mechanism is provided with a partial cutting mechanism in the circumferential direction, so that a cut can be made positively in a part of the workpiece, improving cushioning and cutting during use. Can be achieved.

When the unevenness is small and the number of unevenness is large, one of the two rollers is replaced with an elastic material capable of responding to the protrusion of the roller having the unevenness, for example, rubber or urethane. Since the roller surface can be formed, the manufacturing cost can be reduced.

In the present invention, since a roller surface is formed by stacking a large number of circular plates with irregularities, a pair of irregularities on the circular plate with irregularities is provided with irregularities composed of two or more types of irregularities. To make two or more kinds of irregularities on the circular plate irregularities, to thin out the predetermined irregularities of the irregularities, to give irregularities different from others only to the predetermined irregularities of the predetermined parts, etc. It is very easy to manufacture a roller having a function of creating a predetermined pattern. For the same reason, it is easy to incorporate a circular plate with a cutting blade. Further, even in the case of circular plates having different irregularities, it is very easy to mix and incorporate them into the roller shaft.

Further, the rotational drive of the unevenness imparting device of the present invention is such that the opposing roller is pressed against one rotatably fixed roller by its own weight or by a pressing mechanism.
Since the protrusion of one roller and the recess of the opposing roller mesh with each other, it is possible to supply an inexpensive device that is less likely to break down.

Further, since a mechanism for preventing the sheet-shaped object from being bent after the processing is provided, a concavo-convex processed object having a high flatness can be obtained.

In addition, by applying heat to the textured workpiece from the temperature-controlled roller when the texture is imparted, the thermal deformation of the heat-deformable resin sheet is promoted, and the molding processability is poor, but the heat-deformable resin is not good. Even a sheet can be sufficiently processed to be uneven, and the food material that can be processed easily when heated to an appropriate temperature, for example, the texture of processed food, such as squid, can be enhanced to make the food easy to eat.

Conventionally, no product has been found in which irregularities are imparted to a metal sheet, wire mesh, or corrugated cardboard to actively use the effects peculiar to the irregularities imparted to the metal sheet, wire mesh, or corrugated cardboard. If the positive effect of the unevenness generated by giving the unevenness of the shape suitable for each property and the use mode of each material is positively utilized, mainly in the case of metal sheet, wire mesh, corrugated cardboard, synthetic resin sheet Useful applications as building materials and industrial materials are widespread, and in the case of corrugated cardboard, it can be effectively used as one material for producing fertilizer and greatly contributes to the preservation of the global environment.

Further, when it is difficult to produce a synthetic resin plate because the synthetic resin raw material cannot be supplied appropriately, the raw material is passed through a concavo-convex imparting device for imparting concavities and convexities by a roller, whereby the raw material is conveyed by the unevenness of the roller. And a semi-finished product having irregularities suitable for the next process of producing a smooth synthetic resin plate can be supplied.

Further, the nonwoven fabric provided with the unevenness by the unevenness providing device provided with the heating roller has a unique effect that the unevenness is hardly worn out, and provides a product useful as an underlay material, an abrasive, etc. for foods and the like. Can be.

When unevenness is applied to a thermosetting / thermoplastic synthetic resin film, synthetic resin paper, or synthetic resin plate by using an unevenness providing device provided with a heating roller, the unevenness is smooth without unevenness during the unevenness processing. And a useful application similar to the above-mentioned metal sheet can be obtained.
