Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing an embossing type roll for forming an embossing pattern on a soft metal surface, a soft resin notebook, etc., and a method for forming an embossing pattern on a soft metal surface, etc. using the embossing type roll.

Conventionally, embossing type rolls have been produced by directly engraving a pattern on the outer peripheral surface of the roll, or by engraving a pattern on the outer peripheral surface of the roll and using it as a matrix to form an inverted mold to create a transfer type roll.

Therefore, with the above-mentioned sidewall method, a pattern must be engraved, which requires an extremely large amount of labor and time, and it is extremely difficult to form an embossing pattern on the surface of aluminum fittings, etc. there were.

The present invention is a new technology created in view of these points, and it is possible to form a precise embossing pattern with a simple method, and to easily form a precise and beautiful embossing pattern on the surface of aluminum building materials and fittings, etc. The purpose is to provide a way to do so.

The configuration of the present invention will be described below. The uneven pattern body is made by using, for example, the wood grain of a Japanese cypress board, paper with an intaglio pattern printed on it, or knitted fabric.The process of forming a synthetic resin layer on the top surface of the uneven pattern body to create a pattern. , a step of forming a circular synthetic resin diameter adjusting layer on the circumferential surface of the core roll, bonding the patterned portion of the pattern to the circumferential surface of the diameter adjusting layer to form a master roll. After the step of forming a synthetic resin II layer on the outer surface of the mother mold roll to create a mother mold, the mother mold is used to form a metal roll, a casting layer, an outer covering layer, etc. from the center. This is a manufacturing method for an embossing type roll, which is characterized by creating a compaction type roll consisting of the following: The embossing type roll made by this Reni is equipped with a normal heating mechanism and pressurizing mechanism, and the embossing type roll is still hot after being injection molded. This is a method for forming an embossed song pattern 5V on a soft metal or the like, which is characterized in that an aluminum eye material is pressed by this mold roll to form an imprint of the unevenness V of the mold roll on the surface thereof.

Since the present invention is configured as described above, there is no need to engrave the embossing pattern on the roll surface, and the grain of natural wood can be expressed as is on the mold roll surface, and any complex and elaborate patterns can be expressed. However, it has the characteristic that once intaglio printing is performed on a paper surface, the pattern can be formed exactly on the roll surface.

Embodiments of the present invention will be described below with reference to the drawings. The drawings relate to the present invention; Fig. 1 is a perspective view of the uneven pattern of the waste board, Fig. 2 is a sectional view explaining the process of creating a pattern from the uneven pattern of the intaglio printing paper, and Fig. 3 is a diagram of the master roll. +Iyr side view, Figure 4 is a TFI side view of the mother mold and compaction roll, and Figure @5 is a side view showing an embossing pattern being imprinted on an aluminum building material melt-molded from an injection molding machine.

For the waste board 1, select a grain of wood other than the normal straight grain, and rub or fire it to bring out the summer/winter wood grain. As this waste board uneven pattern body 1, it is placed in the middle bottom of the tray-shaped formwork 3 with the uneven pattern la facing upward, and a flexible synthetic resin material such as urethane southern resin is layered on top of it. Press from above to create pattern 2. In this case, when using a thermosetting resin, heating and pressure pressing is performed, but when using a thermosetting resin material, room temperature pressing is performed for flattening. In order to make it easier to peel off the pattern 2 from the uneven pattern body 1, Kn
Beforehand, apply a release agent such as silicone to the surface of the pattern body 1.

Further, when the uneven pattern body 1 is an intaglio printing pattern paper, 1,
A manuscript is drawn in a large size, scaled down to make the pattern denser, and an intaglio is created.The intaglio is printed on Kent paper, etc. A pattern is formed in a concave shape on an intaglio zinc plate, etc. When printed with this concave plate, the ink is deposited in a sharp mound on the paper surface, and the depth of the concave hole in the concave plate is adjusted as appropriate. It is possible to select the bulge of the ink by forming the ink. The concavo-convex pattern body 1 produced by intaglio printing utilizes the swells of ink printed on a flat paper surface, and has the feature that it can express minute patterns such as Ise-type patterns for small tie-dyeing as embossed patterns.

In addition to intaglio printing paper, rotary printing type paper types can also be used.

The pattern of the pattern 2 formed as described above is the uneven pattern 1
Since the concavities and convexities are formed in the opposite way, when inverting it, the pattern 2 is used as the concavo-convex pattern body 1 and a pattern 2 is created so that the convexities and convexities are further reversed.

Next, a concentric diameter adjusting layer 5 is formed on the circumferential surface of the core roll 4 having an appropriate diameter using a urethane sawdust material or the like. This production method is followed by a conventional method, and a master roll 6 is produced by winding and adhering the pattern 2 on the circumferential surface of the 70 scale diameter layer 5 with its uneven pattern portion 2α facing UEi. The outer circumferential surface of this mother roll 6 has the pattern 2 glued to it, and since the pattern 2 is soft, it is not suitable for a rolling die.
A resin coating layer made of urethane resin or the like is formed on the circumferential surface of the mold to create two halves of the mother molds 7, 7.

As shown in FIGS. 3 and 4, the master molds 7, 7 are formed into two halves vertically at the horizontal line in the figure through which the axis of the master roll 6 passes, and the inner hole wall surface thereof has the above-mentioned shape. The concavo-convex pattern 2a of the pattern type 2 is copied and formed in an inverted manner.

Then, the inner hole surfaces of the master molds 7, 7 are precisely aligned, and a metal roll 8 is installed concentrically with the inner hole axis, so that the outer circumferential surface of the metal roll 8 and the inner surface of the mother mold 7. A heat-resistant hard rubber synthetic resin material is filled in the gap with the inner peripheral surface of the hole to form an outer covering layer 9, and a compaction type roll 10 is constructed. In this case, a low melting point alloy may be thermally sprayed onto the inner circumferential surfaces of the inner holes of the master molds 7, 7 to form a metal outer layer 9', and then the resin outer layer 9 may be formed. This metal outer covering layer 9' has the effect of preventing the uneven pattern of the rolling press roll 10 from deforming, and the resin outer covering layer 9 has the effect of preventing the uneven pattern of the rolling press roll 10
It is effective in reducing weight and production costs.

To create the compaction type roll 10, the inner hole axis of the mother mold 7.7 is made vertical, the lower part of the inner hole 70 is closed with a separate bottom body, and the inner hole is filled with a synthetic resin material from above, heated or There is also a method of filling the inner hole with synthetic laryngeal material by applying pressure and molding, or by injection molding with both ends of the inner hole closed with a base material.
Three choices will be made.

For example, when a heat-resistant gel coat such as Noisol TCA-926 (Evokin resin material) or TOA-932 (trade name) is used to form the vi1 external fat layer, the coating temperature is 250-2.
Excellent heat resistance at 70°C, abrasion resistance, compression resistance, etc.

The compaction type roll 10 created as described above is equipped with a heating mechanism, a pressure mechanism, etc. in a normal configuration and is used to process an embossed pattern on the surface of a vinyl sheet, as well as to apply ink to the uneven patterned surface of the roll. You can also print it.

FIG. 5 is a side view of an embodiment in which an embossing pattern is formed on the side surface of an aluminum building material.

Reference numeral 11 in the figure is a schematic diagram of an injection molding machine, and injection molding machine 1
Two roll-out type rolls 13.13 are arranged vertically in parallel with their axes 13α, 13α horizontally so as to sandwich the top and bottom of the building material 12 made of aluminum taken out from 1, and the cores 13α, 13α are respectively It is supported by a shaft support member (not shown) in a pressurized manner in the direction of the opposing surface of the other rolling press roll.

Ink supply rollers 13b, 13b are respectively disposed in contact with the uneven patterned portions of the circumferential surface of the compaction type rolls 13.13 at desired positions (upper and lower in the figure). The compaction mold rolls 13 and 13 are configured to rotate in opposite directions as shown by the arrows in the figure, and their opposing circumferential surfaces rotate in a direction opposite to the direction in which the injection molding machine 11 is located.

Therefore, adjacent to the rotational direction of the compaction roll 13, another compaction roll 1 = 1 is arranged with the seventh axis 14α in the vertical direction, and the above-mentioned compaction rolls 13, 13 and related matters remain as they are 90; It is arranged as if rotated W.

Here, the aluminum building material 12 injected from the injection molding machine 11 is placed on four rolling press rolls 13, 13.
14, a continuous embossed pattern 15 is formed on both the upper and lower sides.

In addition, as mentioned above, the colored ink or resin agent is applied to the uneven pattern portion of the compaction roll by the ink supply roller, so that the four sides of the aluminum building material 12 are colored simultaneously with the embossing pattern. have.

The melting point of aluminum is about 600℃, and the injection molding machine 1
The aluminum solution in No. 1 is injected from an injection nozzle in a certain mold and cooled by contact with air.
It has a heat resistance of 0°C, so if it is injected from the injection molding machine 11 and the surface temperature is still around 200°C and the surface is still soft, applying pressure with a compaction roll will suffice to embossing the surface. A pattern can be formed by stamping.

Moreover, the molding of the mother mold is not limited to synthetic resin, and of course can be made of cast iron.

The present invention is characterized in that it is made of synthetic resin instead of a metal mold, and in that it can also be used as a printing roller. In other words, instead of forming an embossed pattern on the surface of a building material such as aluminum, a concave pattern is formed on the surface of a compaction roll and intaglio printing is performed on the surface of an aluminum building material using a colored synthetic resin layer colorant, thereby resembling an embossed pattern. Because it is possible to form an uneven pattern, it is possible to print exactly the grain of natural wood on the surface of aluminum building materials, which has a cool feel.Unlike ordinary intaglio and letterpress printing, it is possible to exactly reproduce the unevenness of the wood grain. It has some major features.
