Description

  The present invention relates to an image recording body manufacturing apparatus and a laminating apparatus.

  In recent years, along with the development of image forming technology, means for forming images of the same quality in large quantities and at low cost by various printing methods such as intaglio printing, relief printing, planographic printing, gravure printing, and screen printing are known. Yes. This printing method is also often used for surface printing of information media that can store predetermined information, such as IC cards, magnetic cards, optical cards, or a combination of these, and can communicate with or without contact with external devices. It is used.

  For example, the screen printing requires a large number of printing plates corresponding to the number of images to be printed, and in the case of color printing, printing plates corresponding to the number of colors are further required. Therefore, these printing methods can individually correspond to personal identification information (face photo, name, address, date of birth, various licenses, etc.). An image forming method using a printer or the like employing a sublimation type or melting type thermal transfer method using a ribbon or the like.

  By the way, in the image formation (printing) by electrophotography, the surface of the image carrier is charged and exposed in accordance with an image signal to form an electrostatic latent image due to a potential difference between an exposed portion and a non-exposed portion. This is performed by a method of forming a visible image (toner image) on the surface of the image carrier by electrostatically developing a color powder (image forming material) called toner having a polarity opposite (or the same) as that of charging. In the case of a color image, this process is repeated a plurality of times, or a plurality of image forming devices are arranged in parallel to form a visible color image, and these are transferred and fixed (fixed: mainly by heat) to the image recording medium. This is performed by a method of obtaining a color image by melting and solidifying the color powder by cooling.

  In the electrophotographic system, an electrostatic latent image on the surface of the image carrier is electrically formed by an image signal, so that not only the same image can be formed any number of times, but also different images can be easily handled. It is possible. In addition, the toner image on the surface of the image carrier is transferred to the surface of the image recording body, and the toner image slightly remaining on the surface of the image carrier is also easily removed with a resin blade, a brush, etc. It is possible to easily produce printed matter.

  The toner is usually formed by melting and mixing a heat-meltable resin and a pigment, and optionally additives such as a charge control agent, and pulverizing and granulating the kneaded product. Furthermore, the electrostatic latent image in the electrophotographic method has a considerably higher resolution than the above-mentioned particle toner, and a sufficient resolution is expected even when compared with the resolution of the screen printing or thermal transfer method of the ink ribbon. Is done.

  For color images, cyan, magenta, yellow, and black primary colors are used as color toners, and by mixing these, colors that are theoretically similar to printing are reproduced. Further, in the color toner, since the toner resin and the pigment are blended relatively freely, it is easy to increase the image concealability by the toner.

  Several proposals have already been made for the production of an image recording body (various cards) using the above-described electrophotographic apparatus. Specifically, for example, it has been proposed that personal identification information is printed on a light-transmitting sheet, and that the printing is performed as a mirror image (see, for example, Patent Document 1).

In the above proposal, a light-transmitting sheet on which an image is printed (formed) and a core sheet are laminated, and these are laminated to produce an image recording body (various cards). A belt nip type laminating apparatus is employed as an apparatus used for the laminating.
In general, in a belt nip type laminating apparatus, for example, a flange (regulating member) larger than the diameter of a tension roll called a stopper is provided at an axial end of a tension roll that stretches a belt. When the belt side surface is in contact with the member, the movement in the width direction of the belt is restricted to suppress meandering.

A cam 17 for changing the guide direction of the light transmissive film is provided at a branch portion between the conveyance path 15 and the reverse path 16. When the light transmissive film is reciprocated on the reversing path 16 and returned to the transport path 15 again, the transport direction of the light transmissive film is reversed by 180 ° and the front and back surfaces of the light transmissive film are reversed and transported.

  The collating apparatus 20 includes, for example, a core sheet storage unit 22, a collation receiver (positioning unit) 25, a conveyance path 24 that supplies the core sheet 1 from the core sheet storage unit 22 to the collation receiver 25, and the image forming apparatus 10. The conveyance path 21 is configured to supply the light transmissive film discharged from the discharge port 14 to the collation receiver 25.

  The discharge part of the conveyance path 24 that supplies the core sheet 1 to the collation receiver 25 and the discharge part of the conveyance path 21 that supplies the light transmissive film to the collation receiver 25 are provided in parallel in the height direction. .

  The transport path 21 may be, for example, a plate-like member and a structure provided with a transport roll for transporting the light-transmitting film on the surface thereof, or configured by a rotating endless belt-shaped transport body. May be. Then, at the timing when the light transmissive film is discharged from the image forming apparatus 10, the transport roll and the transport belt rotate and transport to the light transmissive film collation receiver 25.

  As shown in FIGS. 3 and 4, the laminating apparatus 30 is a laminating apparatus that laminates the surface of the core sheet with a light transmissive film by heating and pressing the laminate.

  The laminating apparatus 30 employs a belt nip system composed of a pair of endless belts 31 facing each other, and is configured to easily produce an image recording body on-line. In the pair of endless belts 31, an inlet roll 35 and a tension roll 32 are arranged in this order in the laminated body transport direction inside (inner peripheral side).

  The pair of endless belts 31 are configured so as not to be distorted when the tension roll 32 is pulled by the tension spring 36 while being stretched by the tension roll 32 and the inlet roll 35. The pair of tension rolls 32 and the pair of inlet rolls 35 are installed so as not to nip each other. Thereby, even if the endless belt 31 meanders by continuous operation, the endless belt is returned to a predetermined position while being operated. That is, the meandering of the endless belt 31 is suppressed by controlling the spring force of the tension springs 36 installed at both ends in the axial direction of the pair of tension rolls 32.

  The pair of tension rolls for stretching the endless belt 31, that is, holding the endless belt 31 while applying tension from the inner peripheral surface side of the endless belt 31 corresponds to the inlet roll 35 and the tension roll 32. In addition, a pair (two) of endless belts 31 are disposed, and two pairs of the stretching rolls (the inlet roll 35 and the tension roll 32) are disposed.

The pair of inlet rolls 35 are respectively provided with disc-shaped flanges 35A (regulating members) larger than the roll diameter at both axial ends. The flange 35 </ b> A regulates the movement of the endless belt 31 in the width direction (regulates the position in the width direction of the endless belt 31) by contacting the side surface of the endless belt 31 when meandering. It is a so-called stopper having a function of returning to a specific position.
The flange 35A (regulating member) is not limited to the inlet roll 35, and may be disposed on the tension roll 32. The flange 35A plays a role as a regulating member (stopper), but the shape is not limited to a disk shape, and may be a square plate shape, and may be disposed independently of the roll.

  The pair of endless belts 31 is provided with a plate-like noise suppression member 70 (contact member) that clamps the endless belt 31 between its outer peripheral surface and inner peripheral surface. The noise suppression member 70 sandwiches the endless belt 31 region located between the inlet roll 35 and the tension roll 32 on the opposite side of the endless belt opposite to the side where the pair of endless belts 31 face each other. It is disposed by pressing from the outer peripheral surface toward the inner peripheral surface.

  The noise suppression member 70 is disposed such that one end thereof is in contact with the outer peripheral surface of the endless belt 31 in the vicinity of the position where the flange 35A (regulation member) is disposed. The vicinity of the disposition position indicates a position close to the extent that the movement restriction in the width direction of the endless belt by the flange 35A (regulation member) is not hindered.

  The noise suppression member 70 has a width that is the same as or larger than the width (length in the width direction) of the endless belt 31, and is disposed in contact with the entire width direction of the endless belt 31. However, the present invention is not limited to this, and the noise suppression member 70 only needs to be disposed in contact with at least a part of the outer peripheral surface of the endless belt 31.

  The noise suppression member 70 includes, for example, a base material 70A (for example, a stainless steel base material) and a rubber layer 70B (for example, a silicone rubber layer or a fluorine rubber layer) provided on the base material 70A. The noise suppression member 70 may be composed only of the rubber layer 70B. The rubber layer 70B is brought into contact with the outer peripheral surface and the inner peripheral surface of the endless belt 31, and the noise suppression member 70 is disposed. In addition, as long as the impulse sound of the endless belt 31 can be suppressed, it is not limited to the rubber layer 70B, and may be another layer (for example, a resin layer).

  The noise suppression member 70 is not limited to a form in which the endless belt 31 is sandwiched between the outer peripheral surface and the inner peripheral surface, and may be a form in which the endless belt 31 is brought into contact with only the outer peripheral surface. Even in the case of this embodiment, it is preferable that the endless belt 31 is disposed by being pressed from the outer peripheral surface side.

  The noise suppression member 70 may be disposed only on the endless belt 31 on the side where the flange 35A (regulation member) is provided, and need not be installed on the side through which the laminate passes.

  Here, as the material of the endless belt 31, a metal material (for example, stainless steel) having a small amount of thermal deformation is used. Of course, as the material, a plastic material may be used that has reduced thermal deformation by prescription such as mixing glass. In addition, the inlet roll 35 and the tension roll 32 that return to a predetermined position when the endless belt 31 meanders may be a low friction material (metal or plastic) having a friction coefficient of 0.3 or less. ) Is desirable.

  In addition, in each inner side (inner peripheral side) of the pair of endless belts 31, a heating and pressing roll 34, a cooling plate 39, and a cooling roll 33 are provided between the inlet roll 35 and the tension roll 32 in the stack conveyance direction. They are arranged in this order. These form a nip portion via a pair of endless belts 31.

  In the laminating apparatus 30, the laminate is heated and pressurized by the heating and pressurizing roll 34 disposed behind the inlet roll 35 (downstream side in the laminate transport direction). Through this process, the laminate is heat-sealed. Here, since the pair of inlet rolls 35 is not nipped, the laminated body enters the nip portion of the pair of heating and pressing rolls 34 before the nip force of the pair of endless belts 31 and the heating and pressing rolls 34. While being pre-laminated by preheating, it is conveyed to the nip portion by the heating and pressing roll 34.

  The nip portion formed by the heating and pressing roll 34 is a laminate bonding process, and the laminated body that has passed through the nip portion enters the nip portion formed by the cooling plate 39. Thereby, the laminated body is cooled by the nip portion formed by the cooling plate 39 while maintaining the flatness. The cooling plate 39 is made of a material having high thermal conductivity such as aluminum, and a Teflon (registered trademark) tape or the like is attached to the surface in contact with the endless belt 31 in order to improve the friction. The pair of cooling plates 39 are pressed against the inner peripheral surface of the endless belt 31 with a desired load by an elastic member such as a spring (not shown) to form a nip portion.

  Here, a cooling fan 37 (air flow generating means) that generates an air flow for cooling the cooling plate 39 is installed on the cooling plate 39 in order to cool the heat transmitted from the endless belt 31. . The cooling fan 37 is arranged inside each of the pair of endless belts 31 and on the downstream side of the heating and pressing roll 34 in the stack conveyance direction, that is, between the heating and pressing roll 34 and the cooling roll 33. The cooling plate 39 is cooled by blowing the air flow generated by the cooling fan 37 onto the cooling plate 39.

  The cooling fan 37 is surrounded by a box-shaped member 46 (blocking member) together with the cooling plate 39. Thereby, the air flow generated from the cooling fan 37 does not reach other than the cooling plate 39, that is, does not reach the heating and pressing roll 34. The box-shaped member 46 surrounding the cooling fan 37 is connected to a duct (not shown) that communicates with the outside, and is configured to take in air from the outside.

  The laminated body that has passed through the cooling plate 39 enters the cooling roll 33. The nip force by the pair of cooling rolls 33 is set to be higher than the nip pressure by the cooling plate 39, and the temperature of the laminated body is equal to or lower than the glass transition temperature (Tg) of the light transmissive film when passing through the cooling roll 33. As described above, since the temperature profile of the laminating apparatus 30 is designed, the laminate passes through the nip formed by the pair of cooling rolls 33 while maintaining the flatness. A cleaning device (not shown) is installed to remove dirt and the like on the endless belt 31 due to continuous operation.

  The laminated body that has passed through the laminating apparatus 30 having the above-described configuration (through the bonding process and the cooling process) is laminated while maintaining the flatness, and is discharged to the discharge receiver 61 to obtain an image recording body. Here, when a plurality of individual images are formed on the image recording body, each image is cut to obtain an image recording body of a predetermined size. For example, in the case of a pattern of several cards, the card is cut one by one and laminated on the front and back with a light transmissive film.

  In the image recording body manufacturing apparatus according to the present embodiment described above, the flange 35A (regulating member) for restricting the movement in the width direction of the pair of endless belts 31 constituting the laminating apparatus 30 is disposed. When the (regulating member) and the side surface of the endless belt 31 are in contact with each other, the pair of endless belts 31 are rotationally driven while the meandering of the endless belt 31 is suppressed. As a result, the laminating apparatus 30 is continuously operated.

  On the other hand, the vibration of the endless belt 31 that becomes a vibration source of the impulse noise due to the contact (friction and contact) between the flange 35A (the regulating member) and the side surface of the endless belt 31 Keep it in contact. As a result, the generation of impulse noise is suppressed.

In particular, in the present embodiment, the noise suppressing member 70 is disposed such that one end thereof is in contact with the outer peripheral surface of the endless belt 31 in the vicinity of the position where the flange 35A (regulating member) is disposed. The vibration is suppressed by the noise suppression member 70 before the noise becomes larger, and the generation of impulse noise is suppressed as compared with the case where the arrangement position of the noise suppression member 70 is not taken into consideration. In the present embodiment, the noise suppression member 70 is disposed in the entire region of the endless belt 31 between the inlet roll 35 and the tension roll 32 on the side opposite to the side where the pair of endless belts 31 face each other (however, the noise The restraining member 70 is disposed in a non-contact manner on the inlet roll 35 and the tension roll 32), but is not limited to this. For example, as shown in FIGS. 5 and 6, the flange 35A (regulating member) is disposed. The endless belt 31 may be arranged so as to be unevenly distributed so as to contact only the outer peripheral surface.
Here, FIG. 5 is a schematic side view showing a laminating apparatus according to another embodiment. FIG. 6 is a schematic plan view showing a laminating apparatus according to another embodiment.

  In the present embodiment, the noise suppression member 70 is disposed by pressing from the outer peripheral surface of the endless belt 31 toward the inner peripheral surface. By pressing from the outer peripheral surface of the endless belt 31 in a state where the noise suppression member 70 is stretched toward the inner peripheral surface, the vibration of the endless belt 31 is suppressed as compared with the case where the contact member does not press the endless belt, Generation of impulse noise is suppressed.

  Moreover, in this embodiment, the noise suppression member 70 is arrange | positioned in contact with the outer peripheral surface of the endless belt 31 on the opposite side to the side where a pair of endless belts 31 oppose. The region of the endless belt 31 is a region where the contact region with other members is small and vibration is likely to increase, and the noise suppression member 70 is disposed in contact with the outer peripheral surface of the endless belt 31 in this region. The generation of impulse noise is suppressed as compared with the case where the arrangement position of the noise suppression member 70 is not taken into consideration.

  Further, in the present embodiment, since the noise suppression member 70 is configured in a plate shape, the contact area with the endless belt 31 can be increased compared to other shapes, and therefore, more impulse noise is generated. It is suppressed.

  In the present embodiment, the noise suppression member 70 is disposed so as to sandwich the endless belt 31 so as to contact not only the outer peripheral surface of the endless belt 31 but also the inner peripheral surface. For this reason, since any vibration in the thickness direction of the endless belt 31 is suppressed, the generation of impulse noise is suppressed as compared with the case where the noise suppression member 70 contacts only the outer peripheral surface.

  In the present embodiment, a metal material is used as the material of the endless belt 31, that is, the endless belt 31 is a metal endless belt. The metal endless belt is a metal endless belt that easily generates impulse noise, but even when the endless belt is applied, generation of impulse noise is suppressed.

Moreover, although the form which applied the plate-shaped noise suppression member 70 was demonstrated in this embodiment, it is not restricted to this, You may apply the roll-shaped noise suppression member 70. FIG.
Specifically, as shown in FIGS. 7 and 8, a roll-shaped noise suppression member 70 that sandwiches the pair of endless belts 31 from the outer peripheral surface and the inner peripheral surface is disposed. In this embodiment, two pairs of roll-shaped noise suppression members 70 that sandwich the endless belt 31 are disposed for each endless belt 31. The roll-shaped noise suppressing member 70 disposed inside the endless belt 31 is also disposed as the heating and pressing roll 34 and the cooling roll 33. Of course, the roll-shaped noise suppressing member 70 disposed inside the endless belt 31 may be separately disposed independently of the heating and pressing roll 34 and the cooling roll 33.

  The roll-shaped noise suppression member 70 includes, for example, a shaft 70C (base material: for example, a stainless steel base material) and a rubber layer 70B (for example, a silicone rubber layer or a fluorine rubber layer) provided on the outer peripheral surface of the shaft 70C. The The rubber layer 70B is brought into contact with the outer peripheral surface and the inner peripheral surface of the endless belt 31, and the roll-shaped noise suppressing member 70 is disposed. In addition, as long as the impulse noise of the endless belt 31 can be suppressed, it is not limited to the rubber layer 70B, and may be another layer (for example, a resin layer).

  In the form in which the roll-shaped noise suppression member 70 is disposed, the roll-shaped noise suppression member 70 is rotated with the rotation of the endless belt 31 while suppressing the vibration of the endless belt 31. For this reason, generation | occurrence | production of an impulse noise is suppressed, reducing the rotational resistance of an endless belt compared with the case where the noise suppression member 70 is another shape.

  Here, FIG. 7 is a schematic side view showing a laminating apparatus according to another embodiment. FIG. 8 is a schematic plan view showing a laminating apparatus according to another embodiment.

  Further, in the present embodiment, a mode in which a light transmissive film having an image formed thereon is laminated on a single core sheet and cut as necessary is described, but the present invention is not limited to this. For example, using a core sheet holding holder having one or more window holes, a core sheet prepared in advance with a predetermined size (for example, card size) is inserted and held in the window hole of the core sheet holder Thus, a laminate in which the core sheet holder (core sheet held by the core sheet holder) and a light transmissive film on which an image is formed is laminated may be used. Hereinafter, although this form is demonstrated in detail, it is not necessarily restricted to this.

  In this embodiment, as shown in FIG. 9A, first, the back film 5 is supplied onto the collation receiver 25. Next, as shown in FIG. 9B, the core sheet holding holder 7 in which the core sheet 1 is inserted (set) into the window hole 7 </ b> A is supplied to the collation receiver 25 and laminated on the back film 5. The image 4 on the back film 5 is positioned to coincide with the window hole 7 </ b> A (core sheet 1) of the core sheet holding holder 7. Next, as shown in FIG. 9C, the surface film 3 is supplied to the collation receiver 25 and laminated on the core sheet holding holder 7. At this time, the image 2 of the surface film 3 is positioned so as to coincide with the window hole (core sheet 1) of the core sheet holding holder 7. In this way, a laminated body is formed on the collation receiver 25.

  In the image recording body manufacturing apparatus according to the present embodiment, the mode in which the light transmissive film is laminated on both surfaces of the core sheet has been described. However, the present invention is not limited to this, and depending on the use of the obtained image recording body, The form which laminates a permeable film on the single side | surface of a core sheet may be sufficient.

  Hereinafter, the present invention will be described more specifically with reference to examples. However, these examples do not limit the present invention.

(Example A)
-Laminator-
A laminating apparatus having the same structure as the laminating apparatus 30 described above was used.

-Endless belt-
As the endless belt, a stainless steel belt (thickness 0.2 mm, circumferential length 800 mm, width 340 mm) was used.

-Noise suppression member-
As the noise suppression member, a 2 mm thick silicon rubber whose surface was coated with Teflon (registered trademark) was attached to a stainless base member having a width of 360 mm, a length of 200 mm and a thickness of 1.2 mm. The noise suppression member was pressed down by a force of about 50 N so as to sandwich the belt. The reason why the silicone rubber coated with Teflon (registered trademark) is used is to suppress the sliding resistance with the endless belt.

-Noise measurement method-
As a sound level meter for measuring noise, LA5110 manufactured by Ono Sokki Co., Ltd. was used, and the sound level meter was installed at a position 1 m away from the front of the laminating apparatus 30 as a measurement point.
The laminating apparatus 30 was measured at a heating temperature of 135 ° C., a load between the heating and pressing rolls of 1 KN, and an endless belt feed rate of 5 mm / s. Moreover, the laminated body was not conveyed but measured in the idling state.

(Example B)
Noise was measured in the same manner as in Example A except that the following noise suppression member was used.
-Noise suppression member-
As the noise suppression member, a 2 mm thick silicon rubber whose surface was coated with Teflon (registered trademark) was attached to a stainless base member having a width of 360 mm, a length of 20 mm, and a thickness of 1.2 mm. The noise suppressing member was pressed down both up and down with a force of about 100 N so as to sandwich the belt. In addition, the location which pressed the belt is only one location between the inlet roll and the heating and pressing roll.

(Example C)
Noise was measured in the same manner as in Example A except that the following noise suppression member was used.
-Noise suppression member-
As the noise suppression member, a roll having a silicone rubber layer provided with a thickness of 5 mm on the outer peripheral surface of the shaft (stainless steel) was used. This noise suppression member was each arrange | positioned in the position facing a heating-and-pressing roll. The pressing load on the heating and pressing roll was about 100 KN, respectively.
Similarly, the noise members are also arranged on the cooling roll side. The pressing load on the cooling roll was about 100 KN, respectively.

(Comparative Example A)
The noise suppression member 70 was removed from the laminating apparatus used in Example A, and noise was measured in the same manner as in Example A.

(Evaluation)
Table 1 shows the measurement results of noise obtained in the above examples and comparative examples. The background noise in the table indicates the state where the apparatus is not turned on, the steady state indicates the state where the apparatus is operating, and the impulse noise indicates the sound generated from the belt due to contact / bounce with the flange.
When no noise countermeasure was taken, 84 dB of impulse noise was generated, but all of Examples A to C had an effect of suppressing impulse noise of 15 dB or more. In Example A, since the configuration was such that almost the entire surface of the belt was pressed, the result of the best suppression effect was obtained.
