Description

  The present disclosure relates to a dyeing apparatus that performs dyeing by fixing a dye to a resin body by heating the resin body to which the dye is attached.

  Conventionally, a technique for dyeing a resin body by heating a resin body to which a dye is attached is known. For example, in the method for dyeing a plastic lens disclosed in Patent Document 1, a substrate having a surface coated with a sublimable dye is opposed to the plastic lens in a vacuum atmosphere without contact. Next, by heating with a heating device, the sublimable dye is sublimated, and a dyed layer is formed on the surface of the plastic lens.

  Exemplary embodiments of the present disclosure will be described with reference to the drawings. In the present embodiment, in the following description, the lower left side, the upper right side, the upper left side, and the lower right side of FIG. And Note that the technique of the present disclosure can also be applied to a staining apparatus used for at least a part of the staining process.

<Overview>
This device (dyeing device) 1 is used for dyeing a resin body (in this embodiment, a plastic lens). For example, in the present embodiment, the dyeing apparatus 1 will be described by taking as an example a dyeing apparatus that dyes a resin body by executing both a vapor deposition process and a fixing process. Of course, the dyeing apparatus 1 may be an apparatus that performs only the vapor deposition process or an apparatus that performs only the fixing process. That is, the dyeing apparatus 1 may perform the vapor deposition process and the fixing process using separate apparatuses.

  For example, the dyeing apparatus 1 dyes a resin body by vapor-depositing and fixing a sublimable dye attached to a dyeing substrate on a resin body installed in an installation section. For example, the dyeing apparatus 1 includes a heating unit (heating unit) and the like. For example, the heating means is configured to dye the resin body.

For example, the electromagnetic wave generator 11 is used as the heating means. Of course, any heating means may be used as long as the temperature of the resin body can be adjusted. For example, the heating unit may be configured to flow warm air.
For example, the heating means generates heat in the vapor deposition process and the fixing process in order to dye the resin body. Of course, the heating means may be used in both the vapor deposition step and the fixing step, or may be provided separately.

<Cooling configuration>
Furthermore, the staining apparatus 1 in the present embodiment includes a cooling unit, a flow path, and the like. For example, the flow path is configured to allow gas to flow inside the staining apparatus 1. For example, the cooling means is configured to flow a gas through the flow path. That is, the cooling means generates an air flow. Thus, by providing the cooling means, it is possible to prevent the heating means from being always in a high temperature state and causing the heating means to fail when dyeing is performed. In addition, the temperature inside the apparatus can be lowered, the failure of various components inside the apparatus can be suppressed, the temperature of the apparatus can be prevented from rising, and the safety of the apparatus can be improved. . Furthermore, when dyeing continuously, it is possible to suppress the discoloration of the color or the color unevenness caused by the high temperature in the apparatus or the heating means from being deteriorated.

  For example, the cooling unit 8 may be configured as the cooling unit. In the present embodiment, for example, the cooling fan 8 may be a cooling fan 8 configured to suck gas. In this case, for example, the cooling means has a cooling fan 8, and when the cooling fan 8 is driven, gas is sucked into the dyeing device 1 from the air supply port 9 provided in the dyeing device 1. The gas flowing through the internal flow path is discharged from the cooling fan 8 to the outside of the apparatus. At this time, for example, the cooling fan 8 may be provided above the heating unit, and the gas may be discharged from above the staining apparatus 1. Thus, by setting it as the structure which takes in external air, the inside of the dyeing | staining apparatus 1 can pass gas favorably, and the state which the gas which cooled the heating means and the resin body stays in the dyeing | staining apparatus 1 is suppressed. Therefore, cooling can be performed satisfactorily. Further, by providing the cooling fan 8 above the heating means, the gas collected at the upper part in the dyeing apparatus 1 is efficiently collected outside the dyeing apparatus by utilizing the property that the gas whose temperature has risen gathers upward. Can be released. Thereby, the inside of the dyeing apparatus 1 can be cooled more efficiently.

  For example, the cooling fan may be configured such that air is blown into the dyeing apparatus 1 by using a cooling fan having a structure for blowing air so that the air flows in the flow path. Further, for example, the cooling fan may blow air directly on what it is desired to cool.

  For example, the flow path is formed so that the gas generated by the cooling unit flows through the heating unit that generates heat to dye the resin body, thereby cooling the heating unit. Further, for example, the flow path may be formed so that the gas by the cooling unit flows through the resin body heated by the dyeing process, and the heating unit and the resin body may be cooled. By allowing the gas to flow through the heating means and the resin body as described above, the resin body can be cooled together with the heating means, so that the time for cooling the resin body can be shortened. Thereby, the dyeing | staining time which dye | stains a resin body can be shortened. That is, since the resin body can be cooled together with the heating means, the time can be shortened until the next resin body is dyed. Note that when the resin body is cooled, the installation portion 50 on which the resin body is installed may also be cooled.

  For example, the heating means is provided at a position downstream of the position where the installation section 50 where the resin body is installed after the dyeing process is on standby in the flow path, and gas flows through the flow path by driving the cooling means. In this case, the gas may flow to the heating means through the resin body. In this way, after the gas flows into the resin body, the gas flows into the heating means, so that when the heating means and the resin body are cooled together, the gas whose temperature has not risen is transferred to the resin body. The resin body can be cooled more quickly. That is, since the gas can flow through the resin body before the gas flows through the heating means, the gas whose temperature has not risen by the heating means can be flowed through the resin body, and the resin body can be cooled more quickly. . Thereby, the time for completing the dyeing process of the resin body can be shortened, and the dyeing process can be performed efficiently.

  In addition, for example, the heating unit may be configured so that, during the dyeing process, the resin body is disposed above the position where the resin body is held by the installation unit 50, and the dyeing process is performed by heating from above the resin body. By adopting a configuration in which the dyeing process is performed by heating from above the resin body, the gas heated by the dyeing process can be prevented from moving downward, and only the upper part inside the dyeing apparatus 1 is cooled. The entire interior of the dyeing apparatus 1 can be efficiently cooled only by providing such a cooling means.

  In the present embodiment, the rectifying plate 35 is arranged at a position upstream of the position where the installation unit 50 where the resin body is installed after the dyeing process is on standby, and restricts the flow path for the gas to flow to the resin body. May be provided in the flow path. In this way, by providing the rectifying plate 35 in the flow path of the gas toward the resin body, the size of the flow path (cross-sectional area of the flow path) is reduced, and the flow velocity of the gas toward the resin body is accelerated. More gas can be sent to the resin body, and cooling can be performed efficiently. Further, since the flow path is limited by the rectifying plate 35, most of the gas becomes a flow path through the resin body, and cooling can be performed more efficiently.

<Heat insulation structure>
Furthermore, the dyeing apparatus 1 in the present embodiment includes a heat shield means (heat shield part) 60 and the like. For example, the heat shield 60 is provided between the casing 2 for housing the heating means inside and the heating means, and suppresses heat generated from the heating means from being transferred to the casing 2. . Thereby, it can suppress that the housing | casing 2 which covers the member inside the dyeing | staining apparatus 1 with the heat from a heating means will be heated. Thereby, when a processor touches the dyeing apparatus 1 (housing 2), an injury etc. can be suppressed and a highly safe apparatus can be provided.

  For example, the heat shield 60 is connected to the housing 2 by the connecting member 67. Of course, the heat shield 60 may be connected to a portion different from the housing 2 in the staining apparatus 1. For example, the connecting member 67 is supported by a part of the shielding part 60 and is supported by a part of the housing 2 to connect the shielding part 60 and the housing 2. Thus, the heat transfer from the heat shield 60 to the housing 2 can be suppressed by connecting the shield 60 and the housing 2 in part and reducing the contact area.

  For example, the heat shield 60 may be installed between the housing 2 and the heating means so as to provide a space between the housing 2 and the heat shield 60. And it is good for the gas which flows with a cooling means to pass between the housing | casing 2 and the heat insulation part 60. FIG. Thus, by providing the space between the housing 2 and the heat shield 60, the gas flowing by the cooling means can pass through the space, and the housing 2 and the heat shield 60 are cooled. Therefore, heat transfer from the heat shield 60 to the housing 2 can be suppressed, and the housing 2 covering the members inside the dyeing apparatus 1 can be further suppressed from being heated. .

  Further, for example, the heat shield 60 may be installed between the housing 2 and the heater so that a space is provided between the heater and the heat shield 60. And it is good for the gas which flows with a cooling means to pass between a heating means and the said heat-shielding part 60. FIG. Since the space is provided between the heating unit and the heat shield unit 60, the gas flowing by the cooling unit can pass through the space, and the heating unit and the heat shield unit 60 can be cooled. While being able to suppress the heat transfer from the heat | fever part 60 to the housing | casing 2, it can further suppress that the housing | casing 2 which covers the member inside the dyeing | staining apparatus 1 will be heated.

  For example, when the heating means is configured to stain the resin body with electromagnetic waves, the heat shielding unit 60 may be configured to shield the heat from the heating means and reflect the electromagnetic waves emitted from the heating means. In this case, for example, a configuration in which a member (for example, stainless steel, iron, or the like) having high heat shielding properties and high electromagnetic wave reflectance is used for the shielding portion 60 can be given. Accordingly, it is possible to efficiently perform heating, to efficiently perform a dyeing process, and to perform heat shielding.

<Example>
Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. First, the schematic configuration of the staining apparatus 1 according to the present embodiment will be described with reference to FIGS. 1 and 2. FIG. 1A is a perspective view when viewed from the front side of the staining apparatus 1. FIG.1 (b) is a perspective view at the time of seeing the dyeing apparatus 1 from the back side. FIG. 2 is a perspective view of the staining device 1 in a state where the upper lid portion 4 and the front lid portion 5 are opened when viewed from the front side of the staining device 1.

  The staining apparatus 1 includes a housing 2 having a substantially rectangular parallelepiped shape. The housing 2 accommodates various components for dyeing a resin body (in this embodiment, a plastic lens). For example, the housing 2 includes a base portion 3, an upper lid portion 4, and a front lid portion 5. For example, the base 3 supports the entire staining apparatus 1. For example, the upper lid portion 4 is supported at the rear portion of the base portion 3 so as to be rotatable in the vertical direction. By rotating the front part of the upper cover part 4 upward, the upper part of the housing 2 is opened. For example, the front lid portion 5 has a plate shape and is supported at the lower end of the front side end portion of the base portion 3 so as to be rotatable in the front-rear direction. By rotating the upper part of the front lid 5 forward, the front of the housing 2 is opened. An air supply port (opening) 9 is provided at the front side end of the base 3.

  For example, a display 7 having a touch panel 6 on the surface is provided at the center of the upper surface of the base 3. The operator can input various instructions to the staining apparatus 1 by operating the touch panel 6. For example, two cooling fans 8 for cooling the inside of the staining apparatus 1 are provided side by side on the back side of the upper lid portion 4. Of course, the number of cooling fans 8 is not limited to two. Any structure may be used as long as at least one cooling fan 8 is provided. For example, the cooling fan 8 is used as a cooling unit together with the air supply port 9, and is mainly used for lowering the temperature of an electromagnetic wave generation unit 11 of a heating unit (heating unit) 10 described later. When the cooling fan 8 is driven, air is sucked into the dyeing apparatus 1 from the air supply port 9, and the air flowing inside the dyeing apparatus 1 is discharged from the cooling fan 8 to the outside of the dyeing apparatus 1 (details). Will be described later). In the present embodiment, the case where air is sucked is described as an example, but the present invention is not limited to this. Various gases may be used as the gas flowing inside the staining apparatus 1. For example, oxygen, nitrogen, etc. are mentioned.

  As shown in FIG. 2, the inside of the housing 2 mainly accommodates a heating unit 10, a closing chamber 20, an installation unit back-and-forth movement mechanism 40, an installation unit 50, and the like. For example, the heating unit 10 is provided to heat the plastic lens and the sublimable dye attached to the dyeing substrate 57 (see FIG. 6). For example, the closing chamber 20 closes the periphery of the plastic lens installed in the installation unit 50 and forms a substantially vacuum space inside. For example, the installation unit back-and-forth movement mechanism 40 moves the installation unit 50 in the front-rear direction. In the installation unit 50, a plastic lens and a dyeing substrate 57 are installed. Hereinafter, each configuration will be described in detail with reference to FIGS.

<Heating section>
The heating unit 10 will be described. As shown in FIG. 2, for example, the heating unit 10 includes an electromagnetic wave generation unit 11, a distribution adjustment unit 14, an adjustment unit rotation motor 80 (see FIG. 8), a heat shield unit 60, a motor gear 17, and an adjustment unit mounting gear 18. Prepare.

<Electromagnetic wave generator>
The electromagnetic wave generator 11 will be described. The electromagnetic wave generator 11 of this embodiment generates an electromagnetic wave (infrared rays in this embodiment) that is absorbed by the plastic lens and the dyeing substrate 57 (see FIG. 6). Specifically, an infrared heater 12 that generates infrared rays is used for the electromagnetic wave generator 11. However, other configurations such as a halogen lamp and a far infrared heater can be used for the electromagnetic wave generator 11. Further, the electromagnetic wave generation unit 11 may use a configuration that generates electromagnetic waves such as ultraviolet rays and microwaves. Two electromagnetic wave generators 11 are provided side by side on the inner side of the upper lid part 4 (that is, the front side when the upper lid part 4 is opened) so that two plastic lenses can be dyed simultaneously. . Note that it is not necessary for the plastic lens to absorb all of the electromagnetic waves generated by the electromagnetic wave generator 11. Needless to say, the number of resin bodies that can be dyed simultaneously is not limited to two.

  In the electromagnetic wave generation unit 11, the generation site for generating an electromagnetic wave is formed in an annular shape corresponding to the shape of the opening 15 provided in the distribution adjustment unit 14. By making the shape of the electromagnetic wave generation site correspond to the shape of the opening 15, the electromagnetic wave blocked by the distribution adjusting unit 14 can be compared with the case where the generation site of another shape such as a plate shape or a straight line shape is adopted. The amount decreases. As a result, the electromagnetic wave is efficiently applied to the plastic lens from the opening 15 of the distribution adjusting unit 14. Note that the “corresponding ring” means that the shape of the electromagnetic wave generation site and the shape of the opening 15 of the distribution adjusting unit 14 are substantially the same, and the size (for example, diameter) of both is not necessarily limited. It is not necessary to make it completely coincide.

  In the present embodiment, for example, the electromagnetic wave generation unit 11 is formed with an annular generation site by combining a plurality of infrared heaters 12. Specifically, the two infrared heaters 12 are arranged such that an annular ring is formed by each U-shaped portion of the two U-shaped infrared heaters 12. Infrared heaters having an annular generation site are difficult to manufacture and require high costs compared to other shapes of infrared heaters such as a U-shape. However, by combining a plurality of infrared heaters 12, an annular generation site can be easily formed at low cost. In addition, it cannot be overemphasized that the number and shape of the infrared heater 12 used for one electromagnetic wave generation | occurrence | production site | part 11 can be changed. In the present embodiment, as shown in FIG. 2, two U-shaped infrared heaters 12 are arranged so as to intersect each other. In other words, the plane including the electromagnetic wave generation site of one infrared heater 12 and the plane including the electromagnetic wave generation site of the other infrared heater 12 intersect at the arrangement position of the two infrared heaters 12. As a result, the occurrence of unevenness in the intensity of the electromagnetic wave applied to the plastic lens is suppressed. Further, when the electromagnetic wave generation site is formed in a ring shape, the generation site may be an intermittent ring instead of a continuous ring.

<Distribution adjustment unit>
The distribution adjustment unit 14 will be described. As shown in FIG. 2, two distribution adjusting units 14 are provided side by side so as to be positioned on the front side of each of the two electromagnetic wave generating units 11 in a state where the upper lid 4 is opened. Therefore, when the upper lid 4 is closed, the distribution adjusting unit 14 is positioned below the electromagnetic wave generating unit 11.

  For example, the distribution adjusting unit 14 has a plate shape. The distribution adjusting unit 14 is formed with an opening 15 through which a part of the electromagnetic wave generated by the electromagnetic wave generating unit 11 passes. The dyeing device 1 adjusts the intensity distribution of the electromagnetic wave irradiated downward from the electromagnetic wave generation unit 11 by the opening 15 of the distribution adjustment unit 14. Specifically, the opening 15 is formed in an intermittent annular shape. The dyeing device 1 can easily adjust the intensity of the central part and the intensity of the peripheral part in the electromagnetic wave beam irradiated downward with a simple configuration by allowing the electromagnetic wave to pass through the annular opening 15. . In addition, the shape of the opening part 15 can be suitably changed according to the shape of the resin body to be dyed. Therefore, it is also possible to use openings having other shapes such as a polygonal ring or an elliptical ring.

  For example, each of the two distribution adjustment units 14 is formed with a plurality of openings 15 (in this embodiment, two openings 15A and 15B) that are different in at least one of size and shape. For example, the staining apparatus 1 can easily switch the intensity distribution of the electromagnetic wave irradiated to the object simply by switching the openings 15A and 15B positioned between the object to be heated (for example, a plastic lens) and the electromagnetic wave generator 11. it can. Needless to say, the number of openings 15 formed in the distribution adjusting unit 14 is not limited to two.

  As shown in FIG. 2, the upper lid portion 4 is provided with two motor gears 17 that are rotated by an adjusting portion rotating motor 80 (see FIG. 8). The motor gear 17 meshes with each of the two adjustment unit mounting gears 18 to rotate the adjustment unit mounting gear 18. The distribution adjusting unit 14 is detachably mounted on the tip side of each of the two adjusting unit mounting gears 18 (the front side in the state of FIG. 2). The staining apparatus 1 switches the attitude of the distribution adjustment unit 14 by driving the adjustment unit rotation motor 80 to rotate the distribution adjustment unit 14. As a result, the openings 15A and 15B located between the object to be heated and the electromagnetic wave generator 11 are automatically switched without requiring the operator's work. Note that the method of switching the openings 15A and 15B to be used can be changed. For example, the position of the distribution adjusting unit 14 may be changed by sliding the distribution adjusting unit 14 in parallel without rotating, and the openings 15A and 15B may be switched.

<Heat shield>
The heat shield 60 will be described with reference to FIGS. FIG. 3A is a perspective view of the inside of the upper lid portion 4 of FIG. FIG. 3B is a front view when the inside of the upper lid portion 4 of FIG. 2 is viewed from the front direction. The heat shield 60 is provided between the housing 2 (in the present embodiment, the upper lid 4 of the housing 2) and the electromagnetic wave generator 11 of the heating unit 10 to transfer heat to the housing 2. Suppress. For example, the heat shield part 60 includes a heat shield member 62, a heat shield member 64, a heat shield member 65, a heat shield member 66, a connecting member (in the present embodiment, a column) 67, and the like. For example, each heat shield member shields heat generated by the electromagnetic wave generator 11 and reflects electromagnetic waves emitted from the electromagnetic wave generator 11. In the present embodiment, iron, stainless steel or the like is used for each heat shield member. In this embodiment, stainless steel is used. Thus, by using a member having high heat shielding properties and high electromagnetic wave reflectivity for the shielding member, it is possible to efficiently perform heating, efficiently perform dyeing treatment, and also perform heat shielding. it can. In this embodiment, each heat shield member is configured to use a member having high heat shield properties and high electromagnetic wave reflectivity. However, the present invention is not limited to this. For example, as a member of each heat shield member, at least a member having a high heat shield property may be used. Moreover, it is good also as a structure which uses a different material for each heat-shielding member. In the present embodiment, for example, it is more preferable that the electromagnetic wave reflected by each heat shielding member is reflected in the direction of the plastic lens. By setting it as such a structure, a dyeing | staining process can be performed more efficiently.

  For example, the heat shield member 62 has a plate shape and is provided on the back side of the two electromagnetic wave generators 11. Of course, the heat shield member can be formed in various shapes (for example, a shape whose thickness is partially changed) instead of a plate shape. For example, the heat shield member 62 is fixed to the base portion 68 of the housing 2 at four positions by the connecting member 67. Of course, the heat shield member 62 only needs to be fixed to the base 68, and the fixing position and the total number of connecting members 67 for fixing can be arbitrarily set. For example, in this embodiment, the connecting member 67 is supported by a part of the shielding member 62 and is supported by a part of the housing 2 (in this embodiment, the base 68 of the housing 2), thereby The housing 2 is connected. In this way, by connecting the shielding member 62 and the base portion 68 in part and reducing the area of the connecting portion between the shielding member 62 and the base portion 68, the heat shielding member 62 heated by the heat of the electromagnetic wave generation unit 11 Heat transfer to the housing 2 can be suppressed. Of course, the structure using a connection member with a larger area of a connection part may be sufficient. In the present embodiment, the heat shield member 62 and the housing 2 are connected via the base 68, but the base 68 may be omitted. In this case, the heat shield member 62 is directly fixed to the housing 2 by the connecting member 67.

  Further, in the present embodiment, the heat shield member 62 is fixed to the base portion 68 so as to have a predetermined interval with respect to the housing 2 (the base portion 68 in the present embodiment). Thereby, a space is formed between the base 68 and the heat shield member 62. The air taken in by the cooling means (in this embodiment, the cooling fan 8) can flow (pass through) this space. With such a configuration, the air flowing by the cooling means can pass through the space, and the housing 2 and the heat shield member 62 can be cooled. Therefore, the heat transfer from the heat shield member 62 to the housing 2 can be performed. Heat can be further suppressed. Of course, the heat shield member 62 may be fixed to the housing 2 without providing a space between the housing 2 and the heat shield member 62.

  Furthermore, in the present embodiment, the heat shield member 62 is fixed to the base portion 68 so as to have a predetermined interval with respect to the electromagnetic wave generating portion 11. As a result, a space is formed between the electromagnetic wave generator 11 and the heat shield member 62. The air taken in by the cooling fan 8 can flow through this space. By adopting such a configuration, the air flowing by the cooling means can pass through the space, and the electromagnetic wave generation unit 11 and the heat shield member 62 can be cooled. Heat transfer can be further suppressed. Of course, the heat shield member 62 may be fixed to the housing 2 without providing a space between the electromagnetic wave generator 11 and the heat shield member 62.

  For example, the size (size) of the heat shield member 62 is formed to cover the two electromagnetic wave generators 11. Of course, the size of the heat shield member 62 may be any size as long as it can suppress heat transfer to the housing 2, and may be formed in an arbitrary size. Preferably, it should be formed in a size that can cover at least the electromagnetic wave generator 11. In the present embodiment, the back surface of the electromagnetic wave generator 11 is covered by one heat shield member 62, but the present invention is not limited to this. For example, the heat shield part which covers the back surface of the electromagnetic wave generation part 11 may be comprised by the combination of a plurality (for example, two) heat shield members.

For example, the shielding member 64 is disposed between the two electromagnetic wave generators 11. For example, the heat shield member 64 is used to cover both side portions of the two electromagnetic wave generation units 11 (the side on the center side of the staining apparatus 1). In the present embodiment, one heat shield member 64 is used in common as a heat shield member for covering both side portions of the two electromagnetic wave generators 11. Of course, it is good also as a structure by which the thermal-insulation member 64 for respectively covering the side of the two electromagnetic wave generation parts 11 is provided separately. By disposing the heat shield member 64, it is possible to prevent heat from one electromagnetic wave generation unit 11 in the two electromagnetic wave generation units 11 from being transferred to the other electromagnetic wave generation unit 11. Moreover, it can suppress that an electromagnetic wave is irradiated to the other electromagnetic wave generation part 11 from the one electromagnetic wave generation part 11. FIG. by this. During the dyeing process, each of the left and right electromagnetic wave generators 11 can be adjusted well. That is, by suppressing the influence of the one electromagnetic wave generation unit 11 from being generated in the other electromagnetic wave generation unit 11, the dyeing condition becomes different from the set condition during the dyeing process. It is possible to suppress the dyeing process satisfactorily.
For example, in this embodiment, the heat shield member 64 is fixed to the shield member 62 at two positions by the connecting member 69. For this reason, the heat shield member 64 is fixed to the housing 2 via the shield member 62. Of course, the heat shielding member 69 can arbitrarily set the fixing position and the total number (for example, three) of the connecting members 67 for fixing. For example, the heat shield member 69 may be directly connected to the housing 2 or the base 68 without using the shield member 62. For example, the heat shield member 69 may be configured integrally with the shield member 62.

  For example, the size (size) of the shielding member 64 is formed to cover the sides of the two electromagnetic wave generation units 11. Of course, the size of the shielding member 64 may be any size as long as it can suppress heat transfer between the two electromagnetic wave generation units 11, and may be formed in an arbitrary size. Preferably, it is good to form with the magnitude | size which can cover the side of the electromagnetic wave generation part 11 at least.

  For example, the shielding member 65 and the shielding member 66 are used to cover the side of the electromagnetic wave generation unit 11 (the side of the end portion side of the staining apparatus 1). The shielding member 65 and the shielding member 66 cover the sides of the left and right electromagnetic wave generation units 11, respectively, thereby suppressing the electromagnetic waves irradiated from the side of the electromagnetic wave generation unit 11, and heat from the electromagnetic wave generation unit 11 from the side. Can be prevented from transferring heat to the housing 2 and other members. For example, in this embodiment, the shielding member 65 and the shielding member 66 are configured integrally with the shielding member 62. For this reason, the shielding member 65 and the shielding member 66 are fixed to the base portion 68 by the connecting member 67 similarly to the shielding member 62. Of course, the shielding member 65 and the shielding member 66 may be provided as a separate configuration from the shielding member 62 and connected. For example, the size (size) of the shielding member 65 and the shielding member 66 is formed so as to cover the sides of the two electromagnetic wave generation units 11. Of course, the size of the shielding member 65 and the shielding member 66 may be any size as long as it can suppress heat transfer to the housing 2 and may be formed in any size. Preferably, it is good to form with the magnitude | size which can cover the side of the electromagnetic wave generation part 11 at least.

As described above, by providing the heat shield 60 between the housing 2 and the electromagnetic wave generator 11,
It can suppress that the housing | casing 2 which covers the member inside the dyeing | staining apparatus 1 by the heat_generation | fever of the electromagnetic wave generation part 11 will be heated. Thus, when the processor touches the staining device (housing), it is possible to suppress injury and provide a highly safe device. Further, in the case where the electromagnetic wave generator 11 is provided outside the closed chamber 20 for performing the vapor deposition process or the like as in the present embodiment, it is more useful to provide a heat shield member. . That is, by providing the electromagnetic wave generation unit 11 outside the closed chamber 20, the casing 2 and the electromagnetic wave generation unit 11 are closer to each other. Even in this case, the heat shield member 62 can prevent the casing 2 from being heated. The reason why the electromagnetic wave generator 11 is provided outside the closed chamber 20 includes a reason for preventing the electromagnetic wave generator 11 from being damaged by changing the atmospheric pressure in order to facilitate cleaning of the electromagnetic wave generator 11. . Moreover, the reason for shortening the cycle of the dyeing | staining process by reducing the magnitude | size of the obstruction | occlusion chamber 20 and shortening the time at the time of adjusting atmospheric | air pressure etc. is mentioned.

  Of course, the heat shield 60 is not limited to the above embodiment, and various modifications are possible. For example, the base 68 may be used as a heat shield member. For example, it is good also as a structure which each provides the thermal-insulation member which covers each member of a dyeing | staining apparatus. By setting it as such a structure, it can suppress more that the heat by the electromagnetic wave generation | occurrence | production part 11 transfers to another member or the housing | casing 2. FIG.

<Occlusion room>
The blockage chamber 20 and the configuration associated with the blockage chamber 20 will be described. As shown in FIG. 2, the closed chamber 20 is provided in the approximate center inside the housing 2. When the upper cover 4 of the housing 2 is closed, the closed chamber 20 is positioned below the heating unit 10. As shown in FIG. 4, the shape of the closed chamber 20 is a substantially rectangular box shape. The blocking chamber 20 includes a blocking chamber body 21 and a blocking chamber front wall 22 (see FIGS. 2 and 6). The closed chamber body 21 has a substantially box shape with the front side opened. The blocking chamber front wall 22 can block the opening portion on the front side of the blocking chamber main body 21.

  As shown in FIG. 4, two cylindrical electromagnetic wave passage portions 23 are provided side by side on the upper wall of the closed chamber body 21. The electromagnetic wave generated by the electromagnetic wave generator 11 (see FIG. 2) passes through the space inside the electromagnetic wave passage 23 and reaches the inside of the closed chamber 20. A thermocouple 24 that detects the atmospheric temperature inside the closed chamber 20 is installed in each of the two electromagnetic wave passing portions 23.

  As shown in FIG. 2, a disc-shaped transmission part 25 having a diameter larger than the inner diameter of the electromagnetic wave passing part 23 closes the upper opening of the electromagnetic wave passing part 23 at the upper edge of each of the two electromagnetic wave passing parts 23. To be installed. The transmission part 25 should just be formed with the material which permeate | transmits at least one part of the electromagnetic waves which the electromagnetic wave generation part 11 generates. Furthermore, it is desirable that the material of the transmission part 25 has heat resistance that can withstand the temperature rising by electromagnetic waves. In the present embodiment, heat-resistant glass that transmits infrared rays is used as the material of the transmission part 25. However, this is an example, and the material of the transmission part 25 can be changed. The blocking chamber 20 blocks the internal space by the blocking chamber main body 21, the blocking chamber front wall 22, the electromagnetic wave passing portion 23, and the transmitting portion 25. If the transmission part 25 is installed in a portion between the inside of the blocking chamber 20 and the electromagnetic wave generation unit 11, even if the electromagnetic wave generation unit 11 is installed outside the blocking chamber 20, the electromagnetic wave is irradiated inside the blocking chamber 20. The Therefore, the electromagnetic wave generator 11 is not affected by the change in atmospheric pressure inside the closed chamber 20.

  A supply / exhaust pipe (not shown) is connected to the back side of the closed chamber body 21. The staining apparatus 1 includes a pump 31 and an electromagnetic valve 33 (see FIG. 8). The CPU (control unit) 70 of the staining apparatus 1 can drive the pump 31 to discharge the gas in the closed chamber 20 from the supply / exhaust pipe to the outside and reduce the atmospheric pressure in the closed chamber 20. In addition, the staining apparatus 1 maintains the airtightness in the closed chamber 20 by closing the electromagnetic valve 33. Furthermore, the staining apparatus 1 opens the electromagnetic valve 33 to introduce gas from the outside into the closed chamber 20 in a decompressed state, thereby increasing the atmospheric pressure in the closed chamber 20. Note that a pressure sensor 84 (see FIG. 8) for detecting the atmospheric pressure in the closed chamber 20 is provided in the closed chamber 20 (in this embodiment, the back surface of the closed chamber main body 21). The transmission part 25 is formed with a thickness (for example, 6.5 mm) that can withstand a load (for example, a load due to atmospheric pressure) generated when the atmospheric pressure is reduced. Of course, the transmission part 25 is not limited to the structure which can endure a load with the thickness of the transmission part 25. For example, the transmission part 25 may be able to withstand the load by using a material having high strength, changing the shape of the transmission part (for example, making it spherical), or the like. By setting it as such a structure, even if it is a case where the atmospheric | air pressure in the obstruction | occlusion room 20 is reduced, possibility that the permeation | transmission part 25 will be damaged can be suppressed.

<Installation part longitudinal movement mechanism>
The installation part back-and-forth movement mechanism 40 will be described. As described above, the installation unit longitudinal movement mechanism 40 moves the installation unit 50 (see FIGS. 2 and 5) in the front-rear direction. For example, the installation unit longitudinal movement mechanism 40 includes a longitudinal movement motor 81 (see FIG. 8). The forward / backward movement motor 81 generates power for moving the installation unit 50 back and forth. The installation unit 50 is moved in the front-rear direction by driving the longitudinal motor 81 of the installation unit longitudinal movement mechanism 40. When the installation unit 50 moves rearward by the installation unit back-and-forth movement mechanism 40, the installation unit 50 is accommodated in the closed chamber 20. When the installation unit 50 moves forward, the installation unit 50 is located outside the closed chamber 20 and the housing 2 (see FIG. 2).

<Installation section>
The installation unit 50 will be described. As described above, the plastic lens and the dyeing substrate 57 are installed in the installation unit 50. As shown in FIG. 5, for example, the installation part 50 includes a support plate 51 and two cylindrical parts 53. For example, the support plate 51 is a plate-like member having a substantially rectangular shape in plan view. For example, the inner diameter of the cylindrical portion 53 is slightly larger than the diameter of the plastic lens to be dyed. For example, the two cylindrical portions 53 are provided side by side on the upper surface of the support plate 51. A portion surrounded by each of the two cylindrical portions 53 (that is, a portion of the inner wall of the cylindrical portion 53) is a mounting portion 52. A resin body (a plastic lens in this embodiment) is attached to the attachment portion 52. The plastic lens is heated while being placed (installed) on the mounting portion 52.

  As shown in FIG. 6, for example, the closed chamber front wall 22 is fixed to the front side of the installation unit 50. Further, in the step of depositing the dye on the plastic lens, the substrate holding frame 58 holding the dyeing substrate 57 is placed (installed) on the upper portion of the cylindrical portion 53. In the present embodiment, rectangular paper having an appropriate hardness is used for the dyeing substrate 57. However, other materials such as a glass plate, a heat resistant resin, a ceramic, and a metal film can be used as the material for the dyeing substrate 57. It is desirable to adopt a material that has heat resistance and does not cause a chemical reaction with the dye as the material of the dyeing substrate 57. The lower surface of the dyeing substrate 57 (that is, the surface facing the plastic lens) is an ink (a dyeing material) in which a sublimable dye is dissolved or finely dispersed according to the target dyeing mode. ) Is printed by the printer. Print data (color data) for driving the printer is created by a personal computer (PC) which is an electronic computer so that a desired color / density color is dyed at a location desired by the operator. Therefore, an appropriate amount of sublimable dye is accurately attached to the dyeing substrate 57 at an appropriate position. If the print data is stored, it is easy to execute the same staining a plurality of times. Compared to other dyeing methods such as the dip dyeing method, complex dyeing such as gradation can be easily performed. The color of the dye attached to the dyeing substrate 57 may be one color or a plurality of colors.

  For example, the substrate holding frame 58 is a plate-like member whose outer shape is substantially rectangular in plan view, and holds the dyeing substrate 57. For example, two circular openings are arranged side by side on the base body holding frame 58 so as to correspond to the position and size of the cylindrical portion 53 (see FIG. 5) of the installation portion 50. At the position where the opening is formed, the electromagnetic wave is directly applied to the dyeing substrate 57 without being blocked by the substrate holding frame 58. Further, the dye sublimated from the dyeing substrate 57 smoothly flows to the lower plastic lens side. In the present embodiment, the substrate holding frame 58 is formed of a magnetic material (for example, iron). When the substrate holding frame 58 is installed at the upper end of the cylindrical portion 53, the lower surface of the dyeing substrate 57 faces the plastic lens installed on the mounting portion 52 in a non-contact manner.

  The dyeing apparatus 1 is provided with a retracting mechanism (not shown). The retracting mechanism retracts the dyeing substrate 57 (see FIG. 6) held by the substrate holding frame 58 from the installation unit 50. When the heating (evaporation process) of the dye of the dyeing substrate 57 is completed, the control unit 70 of the dyeing apparatus 1 uses the installation unit back-and-forth movement mechanism 40 (see FIG. 2) to inside the closed chamber main body 21 (see FIG. 4). The installation part 50 (refer FIG. 5) is moved ahead from. At this time, the substrate holding frame 58 is attracted to a magnet (not shown) of the retracting mechanism. Thus, the dyeing substrate 57 held by the substrate holding frame 58 is automatically retracted from the installation unit 50 by the retracting mechanism.

<Cooling means>
The cooling means will be described with reference to FIG. FIG. 7 shows a schematic configuration diagram when the cross section of the staining apparatus 1 is viewed obliquely. In FIG. 7, the case where the installation unit 50 stands by in the space (front chamber) on the front side of the closed chamber 20 will be described as an example. In the present embodiment, the plastic lens stands by in the space on the front side of the closed chamber 20 after the dyeing process. For example, after the dyeing process, after the vapor deposition step (see S4 in FIG. 9), when the plastic lens LE is slowly cooled (S8) and the like.

  For example, in the present embodiment, the cooling means is used to cool the electromagnetic wave generator 11 and the plastic lens LE. For example, in this embodiment, the cooling means includes a cooling fan 8. For example, the cooling fan 8 is used for flowing gas (air in this embodiment) through a flow path for flowing gas inside the staining apparatus 1. The control unit 70 of the staining apparatus 1 controls the driving of the cooling fan 8 to flow air through the flow path. For example, the control unit 70 drives the cooling fan 8 to cause air to be sucked into the dyeing apparatus 1 from the air supply port 9, and the air flowing through the flow path inside the dyeing apparatus 1 is dyed from the cooling fan 8. Release to the outside of the device 1.

  For example, the cooling fan 8 is provided above the electromagnetic wave generator 11 and discharges gas from the upper part inside the staining apparatus 1. Furthermore, in this embodiment, the cooling fan 8 is provided above the position where the installation unit 50 in which the plastic lens LE is installed after the dyeing process is on standby. Of course, the cooling fan 8 may be configured to be provided above at least one of the electromagnetic wave generation unit 11 or the position where the installation unit 50 where the plastic lens LE is installed after the dyeing process is on standby. The air whose temperature has risen has the property of gathering upward. For this reason, by providing the cooling fan 8 above the electromagnetic wave generator 11 as described above, high-temperature air can be efficiently discharged to the outside of the staining apparatus 1. Further, in the present embodiment, the cooling fan 8 is provided above the position where the installation unit 50 where the plastic lens LE is installed after the dyeing process is placed on standby. Can be discharged to the outside of the staining apparatus 1.

The position of the cooling fan 8 is not limited to the above configuration. The position of the cooling fan 8 may be a position where air can flow through the flow path of the staining apparatus 1. Note that the position of the cooling fan 8 depends on at least one of the electromagnetic wave generation unit 11 or the position where the installation unit 50 where the plastic lens LE is installed after the dyeing process is on standby for efficient cooling. It is preferable to change. For example, when the electromagnetic wave generation unit 11 is provided above, a configuration provided above the electromagnetic wave generation unit 11 is preferable. Further, for example, in the case where the electromagnetic wave generation unit 11 is provided below, the electromagnetic fan is irradiated from below, and the plastic lens LE positioned above the electromagnetic wave generation unit 11 is dyed, the cooling fan 8 generates the electromagnetic wave. A cooling fan may be provided below the position of the cooling fan in the present embodiment in accordance with the portion where the portion 11 is located.
What is necessary is just the structure provided at least upwards rather than the position where the installation part 50 in which the plastic lens LE was installed after the dyeing | staining process waits.

  For example, the flow path is formed so that the air generated by the cooling fan 8 flows through the electromagnetic wave generator 11 that has generated heat to dye the plastic lens LE. In this embodiment, the flow path is formed so that air flows not only in the electromagnetic wave generator 11 but also in the plastic lens LE heated by the dyeing process. For example, in this embodiment, the flow path is formed by the air supply port 9, the current plate 35, the cover 36, the air supply port 37, and the like.

  In the present embodiment, the electromagnetic wave generation unit 11 is provided in a position downstream of the position where the installation unit 50 in which the plastic lens LE is installed after the dyeing process is in the flow path. For this reason, when air is caused to flow through the flow path by driving the cooling fan 8, the air flows to the electromagnetic wave generator 11 via the plastic lens LE. As described above, after air flows through the plastic lens LE, the air flows through the electromagnetic wave generation unit 11 so that the air flows through the plastic lens LE before the air flows through the electromagnetic wave generation unit 11. it can. For this reason, air in a state where the temperature has not risen can be passed through the plastic lens LE, and the plastic lens LE can be cooled more quickly. As a result, the time for completing the dyeing process of the plastic lens LE can be shortened, and the dyeing process can be performed efficiently. Further, since the electromagnetic wave generation unit 11 can easily increase the temperature of the air as compared with the plastic lens LE, when the air flows through the electromagnetic wave generation unit 11 before the plastic lens LE, the air having a large temperature increase. Will flow through the plastic lens LE. For this reason, it cannot cool efficiently. In the present embodiment, the air can be efficiently cooled by being configured so that the air flows through the electromagnetic wave generator 11 after the air flows through the plastic lens LE where the temperature rise of the air is small. In the present embodiment, a configuration in which air flows through the plastic lens LE having a small air temperature rise and then flows through the electromagnetic wave generator 11 is described as an example, but the present invention is not limited to this. The electromagnetic wave generation unit 11 may be provided at a position upstream from the position where the installation unit 50 in which the plastic lens LE is installed after the dyeing process is on standby.

  For example, the air supply port 9 is used to suck (take in) air from the outside of the staining apparatus 1 into the interior of the staining apparatus 1. For example, the position of the air supply port 9 is provided above the front side of the staining device 1. Of course, the position of the air inlet 9 can be arranged at an arbitrary position. The position of the air supply port 9 is preferably formed so that air flows at least to the electromagnetic wave generation unit 11 when the cooling fan 8 is driven. More preferably, the position of the air supply port 9 may be formed so that air flows through the electromagnetic wave generator 11 and the plastic lens LE.

  For example, the rectifying plate 35 restricts a flow path for air to flow to the plastic lens LE. For example, by limiting, the area of the flow path can be reduced, and the direction of the flow path (direction of air travel) can be changed. That is, the rectifying plate 35 is used to efficiently flow the air sucked from the air supply port 9 to the plastic lens LE. For example, the current plate 35 is formed using a material such as iron, stainless steel, or plastic (in this embodiment, stainless steel is used).

For example, the rectifying plate 35 is disposed on the back side of the air supply port 9, restricts the air flow path from the air supply port 9, and changes the traveling direction of the air. As a result, the rectifying plate 35 can flow air toward the plastic lens LE disposed in the installation unit 50 that stands by in the space on the front side of the closed chamber 20. In the present embodiment, the rectifying plate 35 is disposed on the back side of the air supply port 9, but the present invention is not limited to this. The rectifying plate 35 may be configured to be disposed at a position upstream of the position where the installation unit 50 in which the plastic lens LE is installed after the dyeing process is waited in the flow path. For example, the current plate 35 may be disposed on the lower back side of the air supply port 9 or may be disposed on the upper back side. Of course, the arrangement position of the rectifying plate 35 is also changed according to the position where the installation unit 50 where the plastic lens LE is installed after the dyeing process is on standby.
In this embodiment, the plastic lens LE and the installation unit 50 are cooled. However, at least the plastic lens LE of the plastic lens LE and the installation unit 50 may be cooled. In this embodiment, the rectifying plate 35 is used to efficiently flow the air sucked from the air supply port 9 to the plastic lens LE, but is not limited to this. A rectifying plate for efficiently flowing air toward the electromagnetic wave generation unit 11 may be provided.

  As described above, by providing the rectifying plate 35 for restricting the flow path in the flow path of air toward the plastic lens LE, the size of the flow path (the cross-sectional area of the flow path) is reduced, and the plastic lens LE. The speed of the air flow toward is accelerated. Further, the direction of the flow path can be changed to the direction toward the plastic lens LE by the rectifying plate, so that most of the air can flow through the plastic lens LE. For this reason, the dyeing | staining apparatus 1 can flow more air to the plastic lens LE, and can perform cooling efficiently.

  For example, the cover 36 is provided with an air supply port (opening) 37. For example, the cover 36 is formed using a material such as iron, stainless steel, or plastic (in this embodiment, iron is used). For example, the cover 36 and the air supply port 37 are used for flowing air that has passed (passed through) the plastic lens LE toward the electromagnetic wave generation unit 11. The cover 36 is used to suppress the electromagnetic wave from the electromagnetic wave generator 11 from being irradiated to various components inside the staining apparatus 1. The air supply port 37 is formed at substantially the same height as the electromagnetic wave generation unit 11. Of course, substantially identical includes completely identical. Thus, by providing the air supply port 37 around the electromagnetic wave generation unit 11, air can be efficiently collected in the electromagnetic wave generation unit 11. For this reason, the electromagnetic wave generator 11 is efficiently cooled. In the present embodiment, the air supply port 37 is described as having an example in which the air supply port 37 is formed at substantially the same height as the electromagnetic wave generator 11, but is not limited thereto. The air supply port 37 may be formed at a position where air can flow through the electromagnetic wave generator 11. More preferably, the air supply port 37 may be formed around the electromagnetic wave generation unit 11.

  The operation of the cooling means will be described. The control unit 70 drives the cooling fan 8. When the cooling fan 8 is driven, the cooling fan 8 releases the air inside the dyeing apparatus 1 to the outside of the dyeing apparatus 1. Accordingly, air existing outside the dyeing apparatus 1 is sucked into the dyeing apparatus 1 from the air supply port 9. The direction of the air sucked from the air supply port 9 is changed downward by the rectifying plate 35. The downwardly directed air hits the plastic lens LE and the installation part 50 and changes the traveling direction upward. The upward air hits the cover 36 and is emitted toward the electromagnetic wave generator 11 from an air supply port 37 provided in the cover 36. The air that has passed through the air supply port 37 flows through the electromagnetic wave generator 11, the heat shield 60, the inside of the housing 2, and the like, and is discharged from the cooling fan 8 to the outside of the staining device 1. For example, when air flows through the region of the electromagnetic wave generation unit 11, the air flows through the space between the electromagnetic wave generation unit 11 and the heat shield unit 60, and the heat shield unit 60 and the housing 2 (in this embodiment, the base 68) Some air also flows through the space between the two.

  As described above, by providing the cooling means, when dyeing is performed, it is possible to prevent the electromagnetic wave generation unit 11 from being constantly in a high temperature state and causing the electromagnetic wave generation unit 11 to fail. In addition, the temperature inside the dyeing apparatus 1 can be lowered, the failure of various components inside the dyeing apparatus 1 can be suppressed, and the temperature of the dyeing apparatus 1 can be prevented from rising, and dyeing can be performed. The safety of the device 1 can be improved. Further, when the dyeing is performed continuously, it is possible to prevent color discoloration or color unevenness from being deteriorated due to a high temperature inside the dyeing apparatus 1 or the temperature of the electromagnetic wave generation unit 11. can do. In addition to the electromagnetic wave generator 11 as in the present embodiment, the time for cooling the plastic lens LE whose temperature has been increased by the dyeing process can be shortened by allowing air to flow through the plastic lens LE as well. Can do. Thereby, the dyeing time for dyeing the plastic lens LE can be shortened. That is, since the plastic lens LE can be cooled together with the electromagnetic wave generator 11, the time can be shortened until the next plastic lens LE is dyed. Further, as in the present embodiment, the electromagnetic wave generator 11 is disposed above the position where the installation unit 50 on which the plastic lens LE is installed after the dyeing process is placed on standby, and is dyed by heating the plastic lens LE from above. Cooling can be performed more efficiently by using a configuration for processing. That is, when the electromagnetic wave generator 11 that greatly increases the temperature of the air is positioned above, it is possible to suppress the gas heated by the dyeing process from proceeding downward. For this reason, high-temperature air can be efficiently collected in the upper part in the apparatus, and cooling can be efficiently performed only by providing a cooling means for cooling only the upper part in the interior of the dyeing apparatus 1. Can do.

  In the present embodiment, the configuration of the flow path for cooling the electromagnetic wave generator 11 and the plastic lens LE has been described as an example, but the present invention is not limited to this. The flow path should just be comprised so that it may go through via the electromagnetic wave generation part 11 at least. For example, the flow path through which air flows may be configured to flow only through the electromagnetic wave generator 11.

  Moreover, the shape of a flow path can be set suitably. For example, as long as the shape of the flow path is configured so as to pass through at least the electromagnetic wave generator 11, the air from the air supply port 9 may be configured to go straight in the back direction of the staining device 1, or the air supply port It is good also as a structure which the air from 9 advances upwards.

  In this embodiment, the cooling fan 8 is driven to suck air from the air supply port 9 and flow the air through the flow path. However, the present invention is not limited to this. For example, as a cooling means, what is necessary is just the structure which can flow air in a flow path. In this case, for example, by using a cooling fan having a configuration for blowing air, the air may be blown into the inside of the dyeing apparatus 1 so that the air flows in the flow path. Moreover, you may make it spray air directly on the electromagnetic wave generation part 11 and the plastic lens LE.

<Electrical configuration>
With reference to FIG. 8, the electrical configuration of the staining apparatus 1 will be described. The staining apparatus 1 includes a CPU (control unit) 70 that controls the staining apparatus 1. The control unit 70 includes a RAM 71, a ROM 72, a nonvolatile memory 73, a touch panel 6, a display 7, a cooling fan 8, a pump 31, a solenoid valve 33, a pressure sensor 84, a thermocouple 24, a heater driving unit 75, and a motor driving unit 76. Are connected via a bus.

  The RAM 71 temporarily stores various information. The ROM 72 stores a control program for controlling the operation of the staining apparatus 1 (for example, a staining control program for controlling the staining process). The nonvolatile memory 73 is a storage medium (for example, a hard disk drive, a flash ROM, or the like) that can retain the stored contents even when power supply is interrupted. The heater driving unit 75 is connected to the two infrared heaters 12 and controls driving of the infrared heaters 12. The motor driving unit 76 controls driving of the adjusting unit rotating motor 80 and the forward / backward moving motor 81.

<Method for producing dyed resin body>
With reference to FIG. 9, the dyeing resin body manufacturing process which concerns on a present Example is demonstrated in detail. First, a step of creating the dyeing substrate 57 is performed (S1). As described above, in this embodiment, the printer prints the ink containing the sublimable dye on the base (paper in this embodiment) based on the print data created by the PC. As a result, a dyeing substrate 57 is created. Therefore, an appropriate amount of sublimable dye is accurately attached to the dyeing substrate 57 at an appropriate position. It is easy to create, change, and save print data on a PC. Therefore, complicated staining is easy, and the same staining can be repeated. However, the present invention can be realized even if the dyeing substrate 57 is formed without using a PC and a printer. For example, the operator may create the dyeing substrate 57 by attaching a sublimation dye to paper using a spray or the like.

  Next, the operator installs the resin body to be dyed and the dyeing substrate 57 created in S1 at a position where dyeing is performed (S2). In this embodiment, a plastic lens that is a resin body is installed on the mounting portion 52 (see FIG. 3) of the installation portion 50. The dyeing substrate 57 is installed on the upper end of the cylindrical portion 53 of the installation unit 50 while being held by the substrate holding frame 58 (see FIG. 5). The dyeing substrate 57 is arranged so that the adhesion surface on which the sublimable dye is adhered faces the resin body in a non-contact manner. Therefore, in this embodiment, the dyeing | staining base | substrate 57 is arrange | positioned so that an adhesion surface may face a downward direction.

  Next, a step of reducing the air pressure around the resin body is performed (S3). In the present embodiment, the gas in the closed chamber 20 is discharged to the outside by the pump 31 (see FIG. 9), whereby the closed chamber 20 is brought into a substantially vacuum state.

  Next, a step of depositing a sublimable dye on the resin body is performed (S4). In the present embodiment, the dyeing substrate 57 is heated by the electromagnetic waves generated by the electromagnetic wave generator 11. As a result, the sublimable dye adhering to the lower surface of the dyeing substrate 57 is heated and sublimated, and is deposited on the upper surface of the resin body.

  Next, a step of increasing the air pressure around the resin body is performed (S5). In the present embodiment, when the electromagnetic valve 33 (see FIG. 9) is opened, external gas is introduced into the closed chamber 20 through the air supply / exhaust pipe. As a result, the atmospheric pressure in the closed chamber 20 is returned to atmospheric pressure.

  Next, a step of retracting the dyeing substrate 57 from the installation unit 50 is performed (S6). In the present embodiment, first, the installation unit 50 is moved to the outside of the closed chamber 20 by the installation unit longitudinal movement mechanism 40. The substrate holding frame 58 holding the dyeing substrate 57 is retracted from the installation unit 50 by a retracting mechanism (not shown). Thereafter, the installation unit 50 is returned to the inside of the closed chamber 20 by the installation unit longitudinal movement mechanism 40.

  Next, a step of fixing the dye to the resin body is performed (S7). In the present embodiment, the electromagnetic wave generator 11 used in the vapor deposition step (S4) is driven again. Since the dyeing substrate 57 is retracted, the electromagnetic wave generated by the electromagnetic wave generator 11 is applied to the resin body without being blocked by the dyeing substrate 57. Therefore, since the dyeing base 57 does not burn, the quality of dyeing does not deteriorate due to burnout or the like. The electromagnetic wave irradiation distribution is appropriately adjusted by the distribution adjusting unit 14. Therefore, the temperature difference of each part in the resin body hardly occurs.

  Next, the resin body is gradually cooled (S8), and the dyed resin body manufacturing process is completed. In the present embodiment, the resin body is kept waiting for a predetermined time or longer in the closed chamber 20 or in a space (front chamber) on the front side of the closed chamber 20. At this time, the cooling fan 8 is driven and air flows inside the dyeing apparatus 1. As a result, the temperature of the resin body is gradually reduced efficiently. The dyeing apparatus 1 moves the resin body whose temperature has decreased to the outside of the housing 2 and ends the process. The dyeing | staining apparatus 1 can reduce the risk of an operator being burned by performing the slow cooling process (S8).

  In this embodiment, a staining process executed by the control unit 70 of the staining apparatus 1 will be described. As described above, the ROM 72 of the staining apparatus 1 stores a staining control program for controlling the staining process. When the power of the staining apparatus 1 is turned on, the control unit 70 executes a staining process according to the staining control program. In the dyeing process, steps S3 to S8 in the dyeing resin body manufacturing process (see FIG. 9) described above are automatically performed.

  As described above, the staining apparatus 1 of the present embodiment can stably perform staining by the gas phase transfer staining method with one apparatus. That is, in this embodiment, the electromagnetic wave generation unit 11 performs both heating during vapor deposition and heating during fixing. Therefore, the staining apparatus 1 has a simple configuration and can be easily downsized. Costs for installing equipment will also decrease.

  Of course, the present invention is not limited to the above-described embodiments, and various modifications are possible. The dyeing apparatus 1 of this embodiment uses the electromagnetic wave generator 11 to perform both the vapor deposition process and the fixing process. As a result, the configuration is simplified. However, it is possible to separately provide means for heating the dye of the dyeing substrate 57 during vapor deposition and means for heating the resin body with electromagnetic waves during fixing. Even in this case, the dyeing apparatus 1 can perform stable dyeing with one apparatus by performing the fixing step under a pressure higher than the pressure during vapor deposition.

  In the present embodiment, the staining apparatus 1 transmits the electromagnetic wave from the outside of the closed chamber 20 to the inside while maintaining the hermeticity in the closed chamber 20 by providing the transmitting portion 25 in the closed chamber 20. Therefore, the dye adhering to the dyeing substrate 57 can be efficiently heated. However, it is also possible to heat the dye with electromagnetic waves without providing the transmission part 25. For example, the dyeing apparatus 1 may heat and sublimate the sublimable dye of the dyeing substrate 57 by heating the iron plate with electromagnetic waves in a state where the dyeing substrate 57 is in contact with the plate surface of the iron plate. In consideration of the effect of changes in atmospheric pressure on the electromagnetic wave generator 11, it is desirable that the electromagnetic wave generator 11 be provided outside the closed chamber 20. However, it is possible to provide the electromagnetic wave generator 11 inside the closed chamber 20.

  In the present embodiment, the case of dyeing a substantially disc-shaped plastic lens for spectacles has been described as an example, but the present invention is not limited to this. The present invention can also be applied when dyeing resin bodies other than plastic lenses. For example, the resin body can be applied to various resin bodies such as a mobile phone cover, a car light cover, an accessory, and a toy. Further, according to the gas phase transfer dyeing according to the present invention, high-quality dyeing is performed regardless of whether the resin body to be dyed is coated. For example, when dyeing plastic lenses for spectacles, a water-repellent coat for obtaining a water-repellent effect, an anti-reflective coat for preventing light reflection, a hard coat for preventing scratches, and preventing cracking It is also possible to apply a primer coat or the like to the plastic lens before or after dyeing.

  In this embodiment, the timing for driving the cooling fan is described by taking as an example the time of slow cooling after fixing, but is not limited thereto. You may drive at any timing from the time of a drive of a device to the time of a stop. For example, the cooling fan 8 may be driven from the start or completion of the vapor deposition step (S4) using a sublimable dye as a resin body. Note that it is preferable that the cooling fan 8 be driven at least while electromagnetic waves are generated, because excess heat in the dyeing process can be released to the outside of the dyeing apparatus 1.
