Description

Specification

Title of the invention Unevenness giving device Technical field

TECHNICAL FIELD The present invention relates to an unevenness imparting device for imparting unevenness to a sheet-like material such as paper, synthetic resin paper, wooden board, metal sheet, and processed food. Background art

Sheet-shaped objects with irregularities have been used as decorative materials with excellent decorativeness, and as wiping paper because of their improved wiping effect.However, sheet-shaped objects with irregularities Is not limited to the applications described above, but is used as a polished paper using the protrusions of the unevenness. It can be used as a blotting paper and as a packing material as a packing material by using the cushioning property of unevenness.

However, the process of providing unevenness is performed on a large scale and industrially using a dedicated manufacturing apparatus. In this case, materials that are readily available, such as pattern paper, synthetic resin paper, and aluminum foil, are used. It is difficult to easily use irregular decorative paper as a decorative paper that suits the user's preference freely.Additionally, uneven paper can be easily provided by using nearby waste paper and waste paper, such as newsprint and copied paper. It is difficult to provide low-cost adsorbent paper and polished paper for everyday 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, two rollers are put together, and a sheet is passed between the rollers to form a sheet. Japanese Patent Application (Japanese Patent Application No. Hei 10-32 26 13 33) by one of the inventor and the applicant (hereinafter referred to as the “application”) describes an apparatus for imparting unevenness to an object.

The concavo-convex imparting device according to the application can apply concavities and convexities excellent in aesthetic sense to the sheet-like material in a uniform appearance. A plate is called a “plate”.) It cannot avoid the effects of thickness tolerance and processing strains such as burrs and shear melting that occur during the manufacturing process of unevenness, such as during punching and laser processing.

That is, unless the circular plates with irregularities forming the surfaces of the two rollers to be engaged are formed with the same thickness in the axial direction of the mouth, they will not engage with each other. If there is a difference in thickness, 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, at the time of assembling the concavo-convex imparting device of the application, it is necessary to process and adjust each time so that the thickness is kept at a constant value every several sheets. A problem has occurred.

In addition, in many cases, the unevenness provided by the unevenness providing device does not require unevenness with a uniform appearance and excellent aesthetic feeling depending on the application.

In addition, since the unevenness providing device according to the application forms a roller by stacking a large number of circular plates with unevenness, the convex portion (21) is sharpened in order to prevent poor engagement, for example, a mounting pyramid. (Fig. 9) In some cases, a round plate with concavities and convexities must be provided even if a lightweight and inexpensive spacing mechanism is required, which results in an increase in the weight of the roller itself. Contributes.

Furthermore, in the case of a thin sheet, depending on the properties of the sheet, a sheet-like material with irregularities may be wrapped around the roller.To prevent this, a plurality of needle-shaped rods are provided near the engagement point of the roller. However, since the unevenness providing device according to the application has a large number of circular plates with unevenness piled up and densely uneven, there is a limit in moving the tip of the needle bar closer to the roller surface. Disclosure of the invention

The invention of the present application was conceived under the circumstances described above, and is a means for easily correcting the thickness variation due to the tolerance of the plate thickness itself of an uneven circular plate and the strain at the time of uneven processing. It is another object of the present invention to provide an unevenness providing device capable of freely adjusting the degree of processing of unevenness as needed, and to provide a lighter unevenness providing device.

It is an object of the present invention to provide a gap holding machine for a circular plate with irregularities or between circular plates with irregularities. This is achieved by providing a device characterized by a structure.

In general, a ring-shaped spacing plate (hereinafter referred to as “spacer”) is used as the spacing mechanism. In the case of a material that can be integrally molded, for example, a synthetic resin material, a circular plate with unevenness is used. The spacing plate can also be configured integrally.

In the following, a case where a spacer is used as the interval maintaining mechanism will be described. The device according to the invention of the present application is the invention according to claim 1, wherein the opposing roller is pressed against one rotatably fixed roller by its own weight or a pressing mechanism, and the unevenness of one roller is reduced. This is more effectively achieved by making the unevenness of the opposed mouths engage with each other and rotating the opposed mouths to rotate the linked mouths together. .

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the accompanying drawings. FIG. 4 is a schematic view showing the usage state of the unevenness providing device.

A sheet-like object (6) is passed between one roller (1) and the counter-opening roller (2) to make the sheet-like object uneven by an uneven pattern (5) on the surface of the opening-closed roller. . FIG. 1 to FIG. 3 show an embodiment of the 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 a roller (1, 2) assembled with these.

The thickness of the circular plate with irregularities is determined by the size of the irregularities required and the thickness and properties of the sheet-like material to be irregularly processed. Generally, a thickness of lmm to 3mm 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 keyway (27) provided on the roller single shaft (23) so that the irregularity of the circular plate with irregularities is reduced. The position is not shifted.

The projection may be provided singly or plurally.

In addition, by appropriately designing the positions of the protrusions, one type of circular plate with concave and convex can be fitted alternately on the front and back sides, so that the pitch of the concave and convex of the circular plate can be appropriately shifted. Non-metallic materials such as hard resin and rubber are used for the circular plate with irregularities (20), in addition to metal materials such as steel, aluminum, stainless steel, titanium, and copper.

FIG. 7 shows a case where 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. Since the shearing effect (scissors effect) can be exerted on the sheet-like material between the protrusions of the roller, the thickness of the spacer (28) is considered in consideration of this shearing effect and the uneven shape of the circular plate with unevenness. Can also be determined.

A commonly used spacer thickness is 0.5 mm to 2 mm.

In consideration of the thickness and properties of the sheet-like material (6), the outer diameter of the stirrer should be round with concavities and convexities when the above-mentioned shearing effect is effective when the processing accuracy of each component is good. The diameter may be larger than the diameter of the concave portion of the plate, but is generally equal to or smaller than the diameter of the concave portion of the circular plate with irregularities.

The inner diameter is determined in consideration of a tolerance based on the diameter of one roller shaft. The same material as that of the round plate with irregularities (20) can be used for the material of the souser, but if a hard non-metallic material is used, it can be manufactured lightweight and inexpensively.

As shown in Fig. 1, the rollers (1, 2) are provided with a circular plate (2, 5) via a retaining ring (25) fitted on the starting end of the roller shaft (23), and a contact plate (24). 0), spacer (28), circular plate with concavities and convexities, and spacer are fitted in this order, and the end is also assembled and configured by holding and fixing with the contact plate and the stopper plate in the same way as the start end. .

Note that a bolt / nut mechanism may be employed instead of the retaining ring.

The length of the uneven part of the roller is determined in consideration of the processing width of the sheet-like material (6) to be unevenly processed, the price of the equipment, etc., about 15 O mm for small household equipment, and corporate equipment. Is about 300 mm.

Roller uniaxial diameter is the length of the uneven part of the roller and the sheet

It is determined in consideration of the characteristics of (6), but it is about 20 mm for small household equipment and about 36 mm for corporate equipment.

Of course, roller lengths and roller uniaxial diameters can be made smaller or larger as needed.

FIG. 7 is a view of the concave portion viewed from the top of the convex portion (21) of the circular plate with concave and convex portions. For easy understanding, the convex portion is indicated by a thick solid line, and the concave portion is indicated by a broken line. It is drawn with a half pitch shift.

The cross section taken along the roller axis is viewed from the direction of arrow A, and the engagement between the two mouths is also shown.

The effects that can be expected in that case are as described above.

As shown in Fig. 8, the shape of the convex part of the circular plate with concavities and convexities can be tapered in the thickness direction toward the outer periphery of the circular plate, and the taper also has a different taper on both sides of the plate. You can also.

By taking this taper, it is possible to facilitate the engagement between the two mouths.

The shape of the convex part of the circular plate with concavities and convexities is shown in Fig. 10 by making the mounting pyramid shape as shown in Fig. 9 the basic shape and reducing the circumferential thickness of the convex part tip in the circumferential direction. When the thickness at the tip of the part 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 by using the plate thickness itself. In this case, the shape shown in FIG. 7 can be obtained.

The convex shape of the mounting pyramid is greater than the convex shape of the quadrangular pyramid, as long as the bottom rectangular part has the same area and a circular plate with the same diameter, more surface area can be formed on the sheet-like material. However, there is an advantage that a larger adsorption effect can be given to the uneven workpiece.

Further, the length of the convex portion and the concave portion in the circumferential direction may be different from each other, so that the mouth (1) and the mouth (2) may be engaged with each other.

The cross-section B in Fig. 10 and the cross-section C in Fig. 11 are cross-sections at the center of the thickness of the circular plate with concavities and convexities. It was drawn.

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

FIG. 5 is a cross-sectional view of the apparatus as viewed from the front, and FIG. 6 is a side view.

A side wall block composed of a pair of side columns (11) and an upper plate (15) is fixed to the base plate (14) with 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 slidably fitted between the side columns above the lower piece (16).

A pair of left and right lower bearing stands are provided with a mouth ring (1) via bearings, and a pair of left upper bearing stands are equipped with rollers (2) via bearings. It is pressed downward by a pressing mechanism consisting of a screw (17) screwed to the plate (15) and a gap adjustment knob (18), and the gap between the mouth rollers can be adjusted freely according to the thickness and properties of the sheet-like material You can do it.

When the handwheel (19) is turned, the roller (1) and mouth roller (2) rotate, and the sheet-like object becomes uneven.

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-like material is thin, irregularities can be provided only by the weight of the roller (2). Industrial applicability

The present invention is embodied in the form described above, and by providing a spacer, has the remarkable industrial application potential as described below.

By providing a spacer, the effect of processing distortion such as burrs that occur in the thickness tolerance of the circular plate and burrs that occur during the manufacturing process of irregularities, for example, during punching, laser processing, and shear melting, can be easily achieved. Processing.

For example, barrel processing for removing burrs generated during punching is not required.

As for the shape of the souser, there is no need to provide a mechanism to prevent idling like the protrusion provided on the inner surface of the circular plate with concavities and convexities.Since a simple ring-shaped structure can be adopted, it is easy to manufacture and inexpensive. Can be adopted.

Also, if you prepare several kinds of spacers with different thicknesses with such a shaper,

In addition, it is extremely easy to make the block of the circular plate with plural concaves and convexes the same thickness, and by further stacking the blocks of the circular plate with plural concaves divided into such blocks, the positional accuracy of the concave and convex is improved. It is possible to easily assemble a long roller with good quality.

In addition, by making the outer diameter of the spacer smaller than the diameter of the circle that forms the bottom of the concave part of the concave and convex circular plate, the processing distortion of the concave and convex part, for example, punching burrs Can be eliminated.

From the above-described effects, it is not necessary to adjust and process the circular plate having a complicated shape with concavities and convexities, and the apparatus can be provided at low cost.

In conventional concavo-convex imparting devices, rollers are formed by stacking a large number of circular plates only.Therefore, in order to prevent poor engagement, it is necessary to sharpen the protruding parts, for example, to form a mounting pyramid, Yes, even if a lightweight and inexpensive spacing mechanism is required, a round plate with concavities and convexities must be provided, which has contributed to increasing the weight of the mouthpiece itself and making the equipment expensive. By providing a spacer, unnecessary processing as described above can be omitted, and a lightweight spacer can be used instead.Thus, it is possible to reduce the weight and cost of the entire device. became. 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 applied to the sheet-like material between the protrusions of the two rollers. (Effect of scissors), the shearing effect can be enhanced by reducing the thickness of the spacer, and it is possible to form an opening in the sheet-like material in this area. Become.

As a result, the sheet-like material of paper can be provided with a larger adsorption performance, and the use of oil and the like as adsorption paper can be further expanded.

A thin sheet-like material may be wound around the roller after roughening, but by providing a plurality of needle-shaped bars on the spacer to prevent this, there is no hindrance to the rotation of the roller. 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 combine the irregularities of the two-sided collar, and it is possible to improve the adsorptivity by simply providing an opening with a convex part. it can.
