Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminating apparatus for laminating an object to be laminated by laminating the object with a laminating film by heating and pressing the laminated film on the object to be laminated.

[0002]

2. Description of the Related Art A recording apparatus having functions such as a printer, a copying machine, and a facsimile, or a recording apparatus used as an output device of a composite electronic device or a workstation including a computer, a word processor, etc., is based on image information. It is configured to record an image (including characters, symbols, and the like) on a recording medium such as a thin film or a plastic thin plate. The recording apparatus can be classified into an ink jet type, a wire dot type, a thermal type, a laser beam type and the like according to a recording method.

[0003] Among them, an ink jet recording apparatus (ink jet recording apparatus) performs recording by discharging ink from a recording means (recording head) to a recording medium. Fine images can be recorded at high speed, and can be recorded on plain paper without requiring special processing. In addition, there are advantages such as low running cost, low noise due to the non-impact method, and easy recording of a color image using various types of inks (for example, color inks). .

[0004] As a recording medium used in an ink jet recording apparatus, recording materials such as paper and plastic sheets,
In some of such base materials, an ink absorbing layer having a pore structure is provided on the surface by coating various fine inorganic materials or the like on the surface to prevent ink from bleeding.

[0005] In particular, printers that require high-quality images use coated paper dedicated to ink, have recently performed photographic recording, and have tended to increase the amount of ink discharged. Sometimes used at maximum water absorption.

In order to further improve the quality of the recorded image, a transparent film that changes irreversibly is formed on the recording surface of the recorded recording material, so that an image having improved image quality and excellent weatherability can be continuously formed. Some can be recorded at

As a recording material having a layer whose physical properties change irreversibly on the recording surface side, for example, there is a recording material in which a porous polymer layer is formed on the recording surface. This porous polymer layer becomes a transparent polymer film by heat treatment and protects the recording surface by coating. There is another type of a porous layer in which a recording material having a resin porous layer formed on the recording surface side is heat-treated to form a transparent resin film covering the recording surface to protect the surface. In any case, by passing the recording material between the heating roller heated to a high temperature and the pressure roller applying a high pressure so that the recording surface and the heating roller face each other, the recording material is transparent on the surface thereof. Protective layer is formed. That is, the recording surface of the recording material comes into contact with the heating roller, and the surface of the heating roller is transferred to the surface of the transparent porous layer of the recording material. Therefore, if there is a flaw on the surface of the heating roller, the flaw is transferred to the surface of the transparent porous layer, which leads to deterioration of image quality.

As a means for solving the above problems and improving the image quality and weatherability, there is a method of forming a transparent polymer layer on the surface after recording on a recording material. That is, the recording material and the transfer material are heated and pressed by heat and pressure by making the surface of the recording material on which the image is recorded face the surface of the porous polymer layer of the transfer material and then passing the pair of rollers maintained at a high temperature and a high pressure. Integrate. Thereafter, after the integrated recording material has sufficiently cooled, only the plastic sheet on the transfer material side is peeled off, so that a transparent porous polymer layer is formed on the surface of the recording material. According to this method, the roller and the porous polymer layer do not come into direct contact with each other, but come into contact with each other via a plastic sheet. Things are obtained.

[0009]

However, the prior art has the following problems. When peeling the plastic sheet from the recording material, it is necessary to sufficiently lower the temperature. Therefore, a heat radiating plate that radiates heat of the recording material and the plastic sheet may be provided downstream of the heating roller and the pressing roller in the transport direction. However, when fixing is performed continuously or when a recording material having a very large heat capacity is fixed, the temperature of the radiator rises, and the temperature of the recording material and the temperature of the plastic sheet may not be sufficiently lowered. When the recording material and the plastic sheet are peeled off at a temperature not lower than the predetermined temperature, a peeling failure occurs on the surface or at the end of the porous polymer layer, and the image quality of the recording material sometimes deteriorates. Although it is effective to provide a cooling means using a fan or a thermo module (Peltier element) in order to suppress the temperature rise of the heat radiator, the cooling means has a disadvantage that it is very expensive and large in size.

The present invention has been made in view of the above circumstances,
It is an object of the present invention to provide a laminating apparatus that shortens the time required for recording and creates a high-quality recorded material that has been subjected to lamination processing.

[0011]

In order to achieve the above object, one embodiment of a laminating apparatus according to the present invention comprises a laminating object conveying means for conveying a laminating object, and a laminating film conveying means for conveying a laminating film. Heating and pressurizing means for heating and pressurizing the object and the film conveyed by each of the conveying means in a superimposed manner,
A heat dissipating means for dissipating heat of the object and the film superimposed by the heating and pressurizing means on the downstream side in the conveying direction of the heating and pressurizing means; -It is characterized in that a heating / pressure releasing means for releasing the heating / pressure of the pressure means is provided.

According to the above arrangement, it is possible to provide a laminating apparatus for shortening the time required for recording and producing a laminated high-quality recorded material.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

<First Embodiment> A first embodiment of the present invention will be described with reference to FIGS.

First, a recording medium which is an object to be laminated, and a transparent film layer forming member which is a laminated film for laminating the recording medium (or
(Referred to as a protective body).

The protective body has a structure in which a single-layer or multilayer thermoplastic resin film layer or latex layer is provided on a heat-resistant base material. As a heat-resistant base material, the shape can be stably maintained under the pressure conditions during the formation of the protective layer, and further under the heating and pressurizing conditions, and peeling occurs when the transparent protective layer is formed on the ink absorbing layer. If it is easy, for example, polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyphenylene salfund (PP
A film or sheet made of a material such as S) and polyethersulfone (PES) can be used, and the thickness thereof can be selected, for example, from a range of 18 μm to 50 μm. When the latex layer is used as the resin layer, the layer is formed such that the thermoplastic particles are fixed on the substrate to such an extent that the thermoplastic particles do not easily fall off the substrate, and can be heated to form a film. Can be

The latex layer is also formed by applying a coating solution containing latex by a roll coating method, a rod bar coating method, a spray coating method, an air knife coating method, a slot die coating method, or the like.
It can be performed by being dried. The layer thickness of the obtained latex layer must finally have a thickness necessary for sufficiently adhering to the ink absorbing layer of the recording medium and for adhering so that no bubbles are present. When the surface roughness of the ink absorbing layer of the recording medium is represented by Rmax, it must have a thickness of at least 70% to 150%, more preferably 100% to 150% of that amount.

A recording medium whose surface is modified by the above-described protective body to provide excellent image quality is formed, for example, as follows. Examples of the substrate include plastic films such as polyethylene and polyethylene terephthalate (PET), and sheets made of paper materials such as high-quality paper, coated paper, and laminated paper. As the ink absorbing layer applied to this surface, a water-soluble polymer emulsion such as polyvinyl alcohol, vinyl acetate, acryl and urethane and a combination thereof, and a coating material in which synthetic silica is further dispersed therein are applied. Can be used. As a coating method, a recording medium can be obtained by applying a roll coating method, a rod bar coating method, a spray coating method, a slot die coating method or the like, followed by drying after application.

An image can be formed using the recording medium and the transparent film layer forming member described above.
Various recording methods can be used for this image formation, and an ink jet recording method can be suitably used. The ink jet recording method is an electrostatic suction method, a method using a piezoelectric element,
There is no particular limitation on the method using a heating element.

The ink used for ink-jet recording may be any ink which can be applied to an ink-jet recording method, such as an ink containing a coloring material such as a dye or a pigment in an aqueous medium. When color recording is performed, a full-color image can be formed by subtractive color mixing using cyan, magenta, yellow and, if necessary, black in accordance with a conventional method.

The formation of the transparent film layer on the ink absorbing layer of the recording medium by the transparent film layer forming member provided with the transparent film layer forming material layer on the heat-resistant base material can be performed, for example, as follows. it can. When an image is formed by ejecting ink to the ink absorbing layer of the recording medium according to the image information according to the ink jet recording method, the transparent film layer forming member of the transparent film layer forming member is formed on the surface of the recording medium on the ink absorbing layer side. The material layers for forming the transparent film layer are pressed against the ink absorbing layer by applying pressure under heating, for example, by laminating the material layers and passing the material layers between a pair of opposed rollers, and forming a transparent film. Thereafter, the substrate is sufficiently cooled, and the base material of the transparent film layer forming member is peeled off from the transparent film layer to obtain a recorded matter having an image formed in the ink absorbing layer protected by the transparent film layer.

FIG. 1 is a schematic view of a laminating apparatus including a step of forming a transparent film layer according to a first embodiment of the present invention. FIG. 2 is a schematic view showing the structure of a recording medium and a member for forming a transparent film layer.

The laminating apparatus shown in FIG. 1 includes an ink jet recording section 1 for discharging ink to perform recording on a surface on the ink absorbing layer side of a recording medium 4 wound in a roll shape, and a recording apparatus. And a laminating unit 2 for forming a transparent film layer on the ink absorbing layer.

The ink jet recording section 1 has an ink jet recording head 3 and discharges ink to an ink absorbing layer 4a on a base material 4b of a recording medium 4 shown in FIG. I do. After image formation, the sheet is cut into a predetermined size by a cutter 9.

A heating roller 6a has a built-in halogen heater for heating the inside of the shaft, and has a rotary encoder on the rotating shaft for detecting the number of rotations of the roller.
A pressing roller 6b is pressed against the heating roller 6a at a predetermined pressure by a pressing roller moving mechanism (not shown).

Reference numeral 21 denotes a first media sensor for detecting the leading end of the recording medium 4. Reference numeral 10 denotes an unwinding device for the transparent film layer forming member 5, and 7 denotes a transparent film layer forming member 5.
Winding device. When the leading end of the recording medium 4 is detected by the first media sensor 21, the pressing roller 6b is moved by a pressing roller moving mechanism (not shown) after a predetermined time.
a and a pair of heated and pressurized rollers 6a and 6b in the direction of arrow A in the figure, and the winding device 7 for the transparent film layer forming member 5 in the direction of arrow B in the figure. Start rotation at a predetermined speed. Here, the predetermined time is a time from when the leading end of the recording medium 4 is detected by the first media sensor 21 to when the leading end of the recording medium 4 reaches the heating roller 6a.

The circumferential speed of the winding device 7 having a clutch mechanism on a drive shaft (not shown) is set slightly higher than the circumferential speed of the heating roller 6a. Will be applied. The unwinding device 10 also has a similar clutch mechanism, and a predetermined tension is applied. A predetermined tension can be applied only by applying a brake to the clutch without rotating the rotating shaft by the drive source. The tension on the unwinding device 10 and the tension on the winding device 7 are both variable. When the heating roller 6a and the pressure roller 6b are not nipped, the transparent film forming member 5 and the recording medium 4 The sheet is conveyed at the rotation speed of the device on the side where the tension is strong. When the heating roller 6a and the pressing roller 6b are nipped, the sheet is conveyed at the rotation speed of the heating roller 6a and the pressing roller 6b.

Next, the transparent film layer forming member 5 is laminated from the transparent film layer forming material layer 5a side to the ink absorbing layer 4a of the image-formed recording medium 4 shown in FIG. It is heated and pressed while passing between the heating and pressing rollers. The heating temperature and pressure of the heating / pressing roller can be set according to the type of the material layer for forming the transparent film layer. By the above processing, the transparent film layer forming material layer 5a is pressed against the ink absorbing layer 4a and formed into a transparent film. During the fixing process, the winding device 7 takes up the output pulse P1 of the rotary encoder provided on the shaft of the heating roller 6a and the output pulse P2 of the rotary encoder provided on the shaft of the winding device 7. The peripheral speed and the winding diameter can be calculated.

Thereafter, when the rear end of the recording medium 4 is detected by the first media sensor 21, the heating until the rear end of the recording medium 4 passes through the heating roller 6a is performed by a rotary encoder provided on the axis of the heating roller 6a. The rotation angle of the roller 6a is monitored. After rotating to this angle, the pressing roller 6b is retracted to the non-pressing position by a pressing roller moving mechanism (not shown), which is a heating / pressing releasing means. In addition,
In the present embodiment, the pressure roller 6b can be moved by the pressure roller moving mechanism as the heating / pressure releasing mechanism. However, the heating roller 6a may be moved.

FIG. 3 is a schematic view of the laminating apparatus when the pressure roller 6b is retracted. As described above, the portion where the transparent film layer forming member 5 and the recording medium 4 are superimposed is heated and pressed by the heating and pressing roller, but the transparent film layer forming member 5 without the recording medium 4 is heated. The only part is not heated and pressed as shown in FIG. 3, and the temperature rise of the transparent film layer forming member 5 can be avoided. When only the transparent film layer forming member 5 is brought into contact with the heating roller 6a, wrinkles may be generated due to heat shrinkage, which can be avoided.

When the pressing roller 6b is retracted to the non-pressing position, the driving force of the heating roller 6a cannot be transmitted to the transparent film layer forming member 5 and the recording medium 4 and cannot be conveyed. Instead, the transparent film layer forming member 5 and the recording medium 4 are transported by the driving force of the winding device 7. When the pressure roller 6b is retracted to the non-pressing position, the tension on the winding device 7 is made larger than the tension on the unwinding device 10, and the transparent film layer forming member 5 and the recording medium 4 are separated from each other. To the side. Instead of increasing the tension on the winding device 7, the tension on the unwinding device 10 may be reduced. However, the absolute value of the tension on the winding device 7 side and the tension value on the unwinding device 10 side, and the relationship between them have a great effect on wrinkles and the like at the time of fixing and peeling.

Next, the transparent film layer forming member 5 and the recording medium 4 are rapidly deprived of the heat possessed by the radiator 23 which is the radiator on the downstream side in the transport direction.
Drop to a temperature close to the temperature of Since the heat capacity of the heat radiator 23 is set to be much larger than the heat capacity of the transparent film layer forming member 5 and the recording medium 4, the heat radiator 23 is formed by receiving heat from the transparent film layer forming member 5 and the recording medium 4. Temperature rise is small. Since only the transparent film layer forming member 5 is not in contact with the heating roller 6a, the temperature is low, and the temperature of the heat radiator 23 does not increase even if it contacts the heat radiator 23. Rather, by positively contacting the low-temperature transparent film layer forming member 5 with the radiator 23, the heat of the radiator 23 can be released to the transparent film layer forming member 5 and the temperature of the radiator 23 can be reduced. it can.

The radiator 23 is a member for forming the transparent film layer 5.
Have a convex shape with respect to the transport direction so as to make contact. The transparent film layer forming member 5 and the recording medium 4 which are heated by the heating / pressing roller and become hot are cooled from the transparent film layer forming member 5 side. Heat radiator 23
Is cooled from the transparent film layer forming member 5 side in order to efficiently remove heat. What is originally desired to be cooled is the transparent film layer forming material layer 5 of the transparent film layer forming member 5.
a and the ink absorbing layer 4 a of the recording medium 4. However, since only the inner part cannot be cooled, the cooling is performed from the transparent film layer forming member 5 side having good heat conduction efficiency. However, if there is no significant difference in heat conduction efficiency between the transparent film layer forming member 5 and the recording medium 4 or the recording medium 4 is better, a heat radiator may be arranged on the recording medium 4 side. When the heat radiator is arranged on the recording medium 4 side, since the width of the transparent film layer forming member 5 is larger than that of the recording medium 4, both ends of the heat radiator 23 are in contact with the transparent film layer forming material layer 5a. Resulting in. The material layer 5a for forming a transparent film layer has an adhesive in order to enhance the adhesion to the recording medium 4. The surface of the heat radiator 23 is coated with a fluorine-based or silicon-based coating so that the adhesive material does not adhere to the heat radiator 23 to cause trouble.

The radiator 23 is made of a material having a very high thermal conductivity, such as aluminum, for example, so that the radiator can have improved heat radiation. In addition, as shown in FIG. 1, by disposing the heat radiator 23 at the position where the transparent film layer forming member 5 is pushed in, the transparent film layer forming member 5 is pulled by the winding device 7 with a predetermined tension. Therefore, the transparent film layer forming member 5 and the radiator 23
Can contact with a predetermined contact pressure to enhance heat transfer.

Reference numeral 26 denotes a second media sensor for detecting the leading end of the recording medium 4. Reference numeral 27 denotes a rear end separation mechanism for separating the rear end of the recording medium 4 and includes fixed guides 27a and 27b and a movable separation shaft 27c. The length of the recording medium 4 in the transport direction, the second media sensor 26 and the rear end separation mechanism 2
Based on the positional relationship with 7, the predetermined number of pulses are counted by the rotary encoder of the heating roller 6a from when the second media sensor 26 detects the leading end of the recording medium 4, and the trailing end separation mechanism 27 is controlled. The movable separation shaft 27c rapidly extrudes the rear end of the recording medium 4 from the transparent film layer forming member 5 side, thereby separating the base material 5b of the transparent film layer forming member 5 at the rear end of the recording medium 4. Can be. Due to the paper path sharply bent by the fixed guide 28 at the leading end of the recording medium 4, the recording medium 4 having high rigidity and the transparent film layer forming material layer 5a can pass through the same paper path as the base material 5b. Separated without being able to. Thus, a recorded matter 8 having the transparent film layer 5c on the ink absorbing layer 4a on which the image shown in FIG. 2c is recorded can be obtained.

After outputting the recorded material 8, the transparent film layer forming member 5 between the heating roller 6a and the fixed guide 28 is not in contact with the recording medium 4 and is not heated by the heating roller 6a. Further, since the transparent film layer forming material layer 5a remains, it can be reused. By reversing the unwinding device 10 by a predetermined angle, the unwinding device 10 can be reused. At this time, since the transparent film layer forming member 5 which is at a low temperature is in contact with the radiator 23, the heat of the radiator 23 can be removed.

The driving force of the unwinding device 10 is used for rewinding the transparent film layer forming member 5. The transparent film layer forming member 5 is unwound toward the unwinding device 10 by changing the balance between the tension of the unwinding device 10 and the tension of the unwinding device 7 to increase the tension of the unwinding device 10. The guide roller 35 is provided with a rotary encoder, and the amount of transport of the transparent film layer forming member 5 is counted to control the amount of rewinding.

Transparent film layer forming member 5 and recording medium 4
Is heated and pressed by the heating and pressing roller, and then the pressing roller 6b is retracted to the non-pressing position by the pressing roller moving mechanism. At this time, the counter of the rotary encoder of the guide roller 35 is reset (C = 0). Thereafter, as the transparent film layer forming member 5 and the recording medium 4 are conveyed in the direction of the rear end separation mechanism 27 and the fixed guide 28 so as to be separated, the counter is counted up (C = C).
+1). When the recorded material 8 is output and a series of peeling operations is completed (C = C1), the unwinding device 10 is driven to rewind the transparent film layer forming member 5. This rewinding operation is continued until the counter of the rotary encoder counts down (C = C-1) and C = 0. By performing the rewinding operation, the used transparent film layer forming member can be used again when the recording medium recorded next is conveyed to the heating roller 6a, or the unused transparent film layer forming member can be used again. The member for forming a transparent film layer can be used effectively without wasting the member.

Here, the transparent film layer forming member 5
When the reusable transparent film layer forming member 5 is unwound after the recording material 8 is peeled off from the recording material 8, the member 8 is brought into contact with the radiator 23 having a higher temperature, and the heat of the radiator 23 is used for forming the low-temperature transparent film layer. Although it escapes to the member 5, the method is not limited to this.

As described above, when the transparent film layer forming member 5 is rewound, the unwinding method is not C = C ₁ → C = 0, but after passing through the position to which the transparent film layer forming member 5 should originally be returned (C = 0). Control may be performed so as to return to C = 0 again.

C = C ₁ → C = 0 → C = −C ₂ → C = 0

With this control, the amount of contact between the low-temperature transparent film layer forming member 5 and the radiator 23 increases, so that more heat can be removed from the radiator 23. However, since the contact time (time required for rewinding) increases with an increase in the amount of contact, it is necessary to take measures such as slightly increasing the rewinding speed and reducing the time required for rewinding.

[0043] Also, as in the _{C = C 1 ⇔ C = 0} , may be controlled so as to reciprocate between the C = C ₁ and C = 0. A temperature sensor is provided on the heat radiator 23, and when the heat radiator 23 falls to a predetermined temperature, the contact between the transparent film layer forming member 5 and the heat radiator 23 is stopped, and control is performed so as to stop at the position of C = 0. May be.

According to the configuration described above, since the means for releasing the heating / pressing of the heating / pressing roller is provided, the portion where the transparent film layer forming member and the recording medium are overlapped is heated / pressed by the roller. And pressurization, but it is possible not to heat and pressurize only the transparent film layer forming member. Therefore, a rise in the temperature of the heat radiator can be suppressed, the time required for recording can be reduced, and a high-quality printed matter laminated can be created.

<Second Embodiment> A second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the transparent film layer forming member 5 is formed in accordance with the temperature of the heat radiator 23.
The sliding speed of the heat radiator 23 is changed to lower the temperature of the heat radiator 23. The basic configuration and operation up to the output of the recorded matter 8 are the same as those of the first embodiment, and thus the description is omitted.

FIG. 4 is a flowchart for determining the sliding speed between the transparent film layer forming member 5 and the heat radiator 23. The operation will be described with reference to this flowchart.

After outputting the recorded material 8, the temperature T of the radiator 23 is detected (S1). The temperature T of the heat radiator 23 is compared with the reference temperature Ta (S2). If the temperature T of the heat radiator 23 is lower than the reference temperature Ta, it is determined that cooling of the heat radiator 23 is not necessary, and the transparent film layer is determined. The rewind speed v of the forming member 5 is set to a higher speed va (S3). If the rewinding speed is high, the time during which the heat radiator 23 and the low-temperature transparent film layer forming member 5 are in contact with each other is short.
Although the amount of heat transmitted from the substrate to the transparent film layer forming member 5 is small, the time required for rewinding can be shortened.

On the other hand, when the temperature T of the heat radiator 23 is higher than the reference value Ta, it is determined that the temperature of the heat radiator 23 needs to be rapidly lowered, and the unwinding speed v of the transparent film layer forming member 5 is reduced. A slower speed vb is set (S4). When the rewinding speed is low, the time during which the heat radiator 23 is in contact with the low-temperature transparent film layer forming member 5 increases, so that the amount of heat transferred from the heat radiator 23 to the transparent film layer forming member 5 increases. The temperature of the radiator 23 can be reduced. However, the time required for rewinding is long.

The temperature T of the heat radiator 23 is compared with the reference temperature Ta, and the rewind speed v of the transparent film layer forming member 5 is controlled to be switched between two stages va and vb. Instead, the speed may be changed steplessly according to the temperature T of the heat radiator 23.
