However, in recent years, the performance of inkjet printers has improved, and it is now possible to print on media such as cloth and vinyl leather, in addition to the traditionally used paper and synthetic paper.

The bonding force between the ink particles in the ink layer printed on the media is not strong, so if strong friction is applied, the ink layer may separate and the coating film and ink may peel off. As a way to prevent
Before applying the coating liquid, a method is used in which the printing surface is rubbed in advance to remove the easily peelable ink from the surface of the ink layer, and then the coating liquid is applied.

From the above, the problems of the conventional coating liquid lamination apparatus are as follows.
Before applying the coating liquid, the printed surface is rubbed to remove easily peelable ink from the surface of the ink layer, and then the coating liquid is applied.
To form an extremely thin coating film even on an output medium on which an embossed expression is applied by using a water-like coating liquid that spreads thinly and has low viscosity.
A laminating apparatus that solves these problems has not yet been embodied.

Subsequently, the lamination apparatus (1) of the present invention includes an angle setting mechanism ( 24), which will be described with reference to FIG.
The first pressing roller (11) and the second pressing roller (12) are rotatably supported by a rotating frame (13), and the rotating frame (13) is supported by a rotating frame fulcrum (13a). 4) is rotatably attached to the handle (22), and when an operator moves it by holding the turning handle (22), it turns from the position indicated by the two-dot chain line to the position indicated by the solid line, and then to the position indicated by the two-dot chain line. , the first pressing roller (11) and the second pressing roller (12) are separated above the application roller (10), and the lock pin (13b) provided on the frame member (4) is engaged with the rotating frame. Rotation is restricted by fitting into a recessed lock pin receiving portion (33b) provided in the holder (33).

Further, at the positions indicated by the solid lines, the positional relationship between the first pressing roller (11), the second pressing roller (12) and the application roller (10) is adjusted so that the positional relationship is suitable for coating the vinyl leather fabric media. , is held by the angle setting mechanism (24).
The first pressing roller (11) and the second pressing roller (12) are arranged so as to surround the front and rear of the coating roller (10), and the first pressing roller (11) is on the side of the means for mounting the original roll (hereinafter referred to as ), the second pressing roller (12) is on the side of the winding means (hereinafter referred to as the downstream side), and the two rollers press the media M onto the coating roller (10) at a predetermined angle at a certain point. (The position indicated by the solid line is hereinafter referred to as the coating liquid application position (laminating position)), and the lock pin (13b) provided on the frame member (4) engages the rotating frame holder (33). ), the rotation of the rotation frame (13) is restricted by being fitted into a recessed lock pin receiving portion (33c) provided in the .

Next, the details of the application roller (10) of the lamination apparatus (1) of the present invention will be described with reference to FIG. The application roller (10) is a roller having a moquette material layer (10a) provided on the surface of a cylindrical core (10b) having a width of 1450 mm, and the outer diameter of the core (10b) is 48.6 mm. , The outer diameter of the coating roller (10) including the moquette material layer (10a) is 58.6 mm, and the thickness of the moquette material layer (10a) is 5.0 mm.
The coating roller (10) is manufactured by spirally winding a belt-shaped moquette material around the core (10b) and adhering it to the metal core (10b). I am making it possible.

The reason why the moquette layer (10a) is provided on the coating roller (10) of the laminating device (1) of the present invention is that the characteristics of the vinyl leather fabric media M and the coating liquid E handled by the laminating device (1) of the present invention are This is because it is necessary to apply the coating liquid E to the surface of M while imprinting it, and the surface of the application roller (10) is desirably made of a soft material.

In addition, since the coating liquid E used for the vinyl leather fabric media M has a very low viscosity, a sufficient amount of the coating liquid E must be applied to the smooth surface of the conventional stainless steel roller unless it is rotated at a considerably high speed. cannot be pumped, but
If a layer capable of absorbing and retaining the coating liquid E is provided on the surface of the application roller (10), the coating liquid E can be sucked up even when the roller is rotated at a slow peripheral speed, and the peripheral speed of the conveyance of the medium M can be improved. Another reason is that the range of possible setting of the peripheral speed of the application roller (10) can be widened, so that the degree of freedom in coating is increased (which is advantageous).

In addition, if the surface of the application roller (10) is made of a soft material, even the valleys of the embossed texture irregularly applied to the surface of the medium M can be completely imprinted.

In addition, even with soft materials, it is easier to use a moquette material with a fluffed surface or a brush-like material than a sponge with a continuous surface (flat surface). , one can enter well into the valleys of the embossed texture.

In addition, the moquette material is a kind of pile fabric, and has a high density surface and short bristles, so that water can be retained between the bristles. This is because it can be rubbed without

In addition, even if it is a moquette material, in the case of a colored moquette material that is generally used,
It may react with the coating liquid E and color the coating liquid E.
In the coating of the vinyl leather media, the scraped-off coating liquid E is reused in order to apply it very thinly, so the moquette material should be a material that does not discolor, such as beige or white, so that the coating liquid E does not become discolored. there is

Next, the squeegee (32) of the laminating apparatus (1) of the present invention will be described with reference to FIG.
The squeegee (32) has a structure in which a silicon sponge (32a) is attached to an attachment plate (32b) elongated in the width direction of the medium M, and a long hole (32d) is provided at the end of the attachment plate (32b). , is attached to the frame member (4) of the laminator (1) by means of attachment screws (32e), and since the width of the attachment plate (32b) is wider than the inner dimension of the frame member (4), it is attached to the frame member (4) It becomes arcuate when hit.
The squeegee (32) can be finely adjusted up and down by the length of the long hole (32d), and a scale plate (34) printed with a scale is provided inside the frame member (4) so that the operator can see the finely adjusted position. is attached, and a point sticker (32c) is attached to the end of the mounting plate (32b).

Also, the silicon sponge (32a) used is very soft with a hardness of 19 degrees.
In general, the hardness of rubber used for squeegees is often from about 45 to 80 degrees. Soft rubber is used because it is necessary to scrape off the liquid.

Also, even if the coating liquid E adheres to the squeegee (32) and hardens, it is desired to be easily peeled off.

Next, the details of coating liquid application by the lamination apparatus (1) of the present invention will be described with reference to FIG. FIG. 6(a) is a side view showing a state in which the rotation frame (13) is rotated to the coating liquid application position by the angle setting mechanism (24), and FIG. It is the figure seen from the back side of.

In the conveying state of the medium M at the coating liquid application position, the incident angle (θ1 in FIG. 6) from the first pressing roller (11) to the application roller (10) is about 30 degrees, and the angle from the application roller (10) to the application roller (10) is about 30 degrees. 2 The exit angle (θ2 in FIG. 6) toward the pressing roller (12) is about 7 degrees, and the medium M is wound around the coating roller (10) in an arc of about 40 degrees (θ3 in FIG. 6),

In applying the coating liquid E to the medium M, the rotation direction of the application roller (10) rotates in a direction opposite to the direction in which the medium M is conveyed (a direction called reverse coating),
The peripheral speed of the application roller (10) is a peripheral speed that is 3 to 10 times the peripheral speed at which the medium M is conveyed, and is a peripheral speed at which the same portion of the surface of the medium M can be rubbed at least 3 times or more. there is
The reason why the peripheral speed of the application roller (10) is 3 to 10 times the peripheral speed of the medium M to be conveyed is that if the peripheral speed is 3 to 10 times, while removing the easily peelable ink near the surface of the ink layer, This is because the coating liquid can be applied while being imprinted on the coating liquid E medium that retains water in the moquette material layer. (If the peripheral speed of the application roller (10) is too high, the number of times of imprinting will be too large, and frictional heat will be generated on the surface of the media M, causing discoloration and abrasion of the ink layer. up to 10 times is desirable.)

Next, the function of the squeegee (32) will be explained. The squeegee (32) contacts the medium M from the lower side of the medium M toward the second pressing roller (12) from the application roller (10), and the contact angle is an acute angle (attack angle) in the direction in which the medium M advances. The angle is 60 degrees (θ4 in FIG. 6), and the contact line is an arc-shaped contact line that faces the direction in which the medium M advances and bulges out at the center. The tip follows the unevenness of the embossed texture of the medium M and scrapes off the coating liquid E to make an extremely thin coating thickness,
It is dried by a heater (19) and air-cooled by a fan (20) to form a very thin coating film that adheres to the ink particles.

Also, the coating liquid E scraped off by the squeegee (32) is collected in the liquid box E and reused.

The reason why the attack angle (θ2 in FIG. 6) of the squeegee (32) is set to 60 degrees in the lamination apparatus (1) of the present invention is that when the attack angle is increased, the silicon sponge (32a) and the medium M The contact resistance increases and chattering occurs, and the coating layer of the coating liquid E on the surface of the medium M becomes uneven. Conversely, if the angle of attack is reduced, the flexibility of the silicone sponge (32a) weakens the ability to scrape off, and the coating thickness of the coating liquid E cannot be reduced.

In addition, the reason why the contact line (arcuate direction) of the squeegee (32) to the media M projects in the direction in which the media M advances is that the squeegee (32) scrapes off the coating liquid E. This is to prevent a gap from forming between the media M and the silicon sponge (32a) due to warping due to the reaction force.
