Description

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

  Conventionally, a technique for fixing a dye by heating the resin body by irradiating infrared rays onto the resin body to which the dye is attached is known. For example, the staining apparatus disclosed in Patent Document 1 irradiates a plastic lens with infrared rays in a state where a region of the plastic lens where no dye is deposited is shielded by a shielding unit. As a result, the occurrence of yellowing due to heating is suppressed at the site where the dye is not deposited.

Japanese Patent No. 4802138

  When the resin body is irradiated with electromagnetic waves such as infrared rays and heated, the temperature rise of each part of the resin body may not be appropriately controlled due to the influence of the shape of the resin body. For example, in order to heat a substantially plate-shaped resin body uniformly, the case where the electromagnetic wave is uniformly irradiated to the plate surface of the resin body is assumed. In this case, if the thickness of the resin body is not constant, the temperature of the thick part is less likely to rise than the temperature of the thin part, and thus a temperature difference may occur in each part of the resin body. That is, it is difficult to fix the dye by heating the resin body by irradiation of electromagnetic waves while appropriately controlling the temperature rise of each part of the resin body.

  An object of this invention is to provide the dyeing | staining apparatus which can fix a dye by heating a resin body by irradiation of electromagnetic waves, controlling appropriately the temperature rise of each site | part of a resin body.

  The dyeing apparatus according to the present invention is a dyeing apparatus for dyeing the resin body by fixing the dye attached to the surface of the resin body by heating the resin body installed in the installation section. An electromagnetic wave generating means for generating an electromagnetic wave, and a distribution adjusting means for adjusting an intensity distribution of the electromagnetic wave applied to the resin body from the electromagnetic wave generating means.

  The dyeing apparatus according to the present invention can fix the dye by heating the resin body by irradiation of electromagnetic waves while appropriately controlling the temperature rise of each part of the resin body.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, a schematic configuration of the staining apparatus 1 according to the present embodiment will be described with reference to FIGS. 1 and 2. In the following description, the diagonally lower left side, the diagonally upper right side, the diagonally upper left side, and the diagonally lower right side of FIGS. 1 and 2 are the front side, the rear side, the left side, and the right side, respectively.

  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). The housing 2 includes a base portion 3, an upper lid portion 4, and a front lid portion 5. The base 3 supports the entire staining apparatus 1. 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. 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.

  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. Two cooling fans 8 (see FIG. 9) for cooling the inside of the staining apparatus 1 are provided side by side on the back side of the upper lid portion 4.

  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. The heating unit 10 is provided to heat the plastic lens and the sublimable dye attached to the dyeing substrate 57 (see FIG. 7). The blocking chamber 20 closes the periphery of the plastic lens installed in the installation unit 50 and forms a substantially vacuum space inside. The installation part back-and-forth movement mechanism 40 moves the installation part 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.

  The heating unit 10 will be described. As shown in FIG. 2, the heating unit 10 mainly includes an electromagnetic wave generation unit 11, a distribution adjustment unit 14, an adjustment unit rotation motor 80 (see FIG. 9), a motor gear 17, and an adjustment unit mounting gear 18.

  The electromagnetic wave generator 11 will be described. The electromagnetic wave generator 11 of the present embodiment generates electromagnetic waves (in this case, infrared rays) that are absorbed by the plastic lens and the dyeing substrate 57 (see FIG. 7). 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 can be used for the electromagnetic wave generator 11. Moreover, you may use the structure which generate | occur | produces electromagnetic waves, such as an ultraviolet-ray and a microwave. 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 an opening 15 (see FIG. 3) provided in the distribution adjustment unit 14 described later. In detail, since the opening 15 of the present embodiment has an annular shape, an electromagnetic wave generation site is also formed in an annular shape. For example, when the shape of the opening 15 is formed in a rectangular ring shape, it is desirable that the electromagnetic wave generation site is also formed in a rectangular ring shape. 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, electromagnetic waves are efficiently applied to the plastic lens from the opening 15. Note that the “corresponding ring” does not indicate that the shape and size of the electromagnetic wave generation site and the shape and size of the opening 15 are completely the same. That is, it is only necessary that the shapes of the two are substantially the same, and the sizes (for example, diameters) of the two are not necessarily matched.

  In the electromagnetic wave generation unit 11 of the present embodiment, an annular generation site is formed 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. Moreover, in this embodiment, as shown in FIG. 2, the two U-shaped infrared heaters 12 are arranged so as to intersect. 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.

  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.

  As shown in FIG. 3, 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. . More specifically, the opening 15 of the present embodiment has a shape in which four radial support pieces 16 for supporting the inner disk-shaped portion are formed at equal intervals in an annular hole. However, when the opening 15 is formed in an annular shape, the opening 15 may be formed in a continuous annular shape. The annular opening 15 may be formed by arranging a plurality of holes in an annular shape. Moreover, in this embodiment, in order to adjust appropriately the intensity distribution of the electromagnetic wave irradiated to a circular plastic lens, the shape of the opening part 15 is formed in the annular | circular shape. However, the shape of the opening 15 can be appropriately 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.

  Each of the two distribution adjustment portions 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. In the present embodiment, the size (diameter) of the opening 15A is larger than the size of the opening 15B. The staining apparatus 1 can easily switch the intensity distribution of the electromagnetic wave irradiated to the object by simply switching the openings 15A and 15B positioned between the object to be heated (for example, a plastic lens) and the electromagnetic wave generator 11. 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. 9). 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.

  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 7). 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.

  As shown in FIGS. 2 and 4, a holding plate 27 for holding the position of the transmission part 25 is provided above the blocking chamber 20. The holding plate 27 is a plate-like member having a rectangular outer shape, and includes two openings with a diameter smaller than the diameter of the disk-shaped transmission part 25 arranged side by side. A rear end portion of the holding plate 27 is attached to the housing 2 so as to be rotatable. When the holding plate 27 is rotated upward, the transmission portion 25 can be installed and removed from the electromagnetic wave passage portion 23 (see FIG. 2). When the holding plate 27 is rotated forward, the transmitting portion 25 is pressed from above by the holding plate 27, and the position of the transmitting portion 25 with respect to the electromagnetic wave passing portion 23 is held. Although details will be described later, in the step of depositing the dye on the plastic lens, the inside of the closed chamber 20 is brought into a substantially vacuum state. In this case, the inside of the closed chamber 20 is decompressed, so that the position of the transmission part 25 is reliably fixed. Therefore, the holding plate 27 does not need to press the transmission part 25 with a strong force.

  As shown in FIG. 4, an atmospheric pressure control unit 30 is provided on the back side of the closed chamber body 21. A supply / exhaust pipe (not shown) is connected between the atmospheric pressure control unit 30 and the back surface of the closed chamber body 21. The atmospheric pressure control unit 30 includes a pump 31 and an electromagnetic valve 33 (see FIG. 9). The dyeing apparatus 1 can drive the pump 31 to discharge the gas in the closed chamber 20 from the supply / exhaust pipe to the outside, thereby reducing 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. 9) that detects 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 installation part back-and-forth movement mechanism 40 will be described. As described above, the installation part back-and-forth movement mechanism 40 moves the installation part 50 (see FIGS. 2 and 6) in the front-rear direction. 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).

  As shown in FIG. 5, the installation unit longitudinal movement mechanism 40 includes a main frame 41, a center frame 42, two side frames 43, a longitudinal movement motor 81, a drive pulley 45, a driven pulley 46, and a belt 47. The main frame 41 is disposed at the bottom of the housing 2 (see FIG. 2), and supports the entire installation unit longitudinal movement mechanism 40. The center frame 42 has a T shape in plan view, and is disposed at the center in the left-right direction of the installation unit longitudinal movement mechanism 40. The front side end portion of the center frame 42 is fixed to the bottom surface of at least one of the installation portion 50 and the closed chamber front wall 22 (see FIG. 7). In the present embodiment, the installation unit 50 is attached to the front wall 22 of the closed chamber. The two side frames 43 are substantially rod-shaped members extending in the front-rear direction, and are attached to the left and right sides of the center frame 42. The side frame 43 is guided to move in the front-rear direction on the left and right of the main frame 41. The front side (front end side) of the side frame 43 is fixed to each of the left and right sides of the front wall 22 of the closed chamber.

  The longitudinal motion motor 81 is installed at the rear end portion of the main frame 41 and generates power for moving the installation portion 50 back and forth. The drive pulley 45 is rotatably held at the center in the left-right direction at the rear end portion of the main frame 41, and is rotated by the power of the longitudinal movement motor 81. The driven pulley 46 is rotatably held at the center in the left-right direction at the tip of the main frame 41. Both the rotation shaft of the drive pulley 45 and the rotation shaft of the driven pulley 46 extend in the vertical direction. The belt 47 is stretched over the drive pulley 45 and the driven pulley 46. A rear end portion of the center frame 42 is fixed to the belt 47.

  When the longitudinal motor 81 rotates, the drive pulley 45 rotates. Along with this, the belt 47 stretched around the drive pulley 45 rotates. When the belt 47 rotates, the center frame 42 fixed to the belt 47 moves in the front-rear direction. As a result, the installation part 50 fixed to the center frame 42 moves in the front-rear direction. The longitudinal movement of the installation unit 50 is guided by the side frame 43 and the main frame 41.

  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. 6, the installation part 50 includes a support plate 51 and two cylindrical parts 53. The support plate 51 is a plate-like member having a substantially rectangular shape in plan view. The inner diameter of the cylindrical portion 53 is slightly larger than the diameter of the plastic lens to be dyed. The two cylindrical portions 53 are provided on the upper surface of the support plate 51 side by side. Of 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 bottom wall of the cylindrical portion 53) is an attachment body mounting portion 52.

  An adhesive body 55 having an adhesive property to a resin body (in this embodiment, a plastic lens) is attached to the central portion of the adhesive body mounting portion 52. The plastic lens is placed (installed) on the upper surface of the adhering body 55, and heated with the adhering body 55 attached thereto. Therefore, even when the temperature of a part of the plastic lens is higher than the temperature of the other part, the heat is diffused to the adhering body 55, so that the temperature difference of each part of the plastic lens is reduced. The attachment body mounting unit 52 attaches the attachment body 55 in a detachable manner. Therefore, the operator can easily replace the attachment 55 when the attachment 55 is soiled or damaged, or when it is desired to change to another attachment 55 having a different shape or the like.

  It is desirable to use a material having a thermal conductivity equal to or higher than that of the plastic lens as the material of the attachment body 55. In this case, the heat of the portion of the plastic lens that is higher in temperature than the other portions is efficiently diffused to the adherend 55. As a result, the temperature difference of each part of the plastic lens is further reduced. However, the thermal conductivity of the attachment 55 may be equal to the thermal conductivity of the plastic lens. Even if the thermal conductivity of the adhering body 55 is lower than the thermal conductivity of the plastic lens, the temperature difference is reduced as compared with the case where the adhering body 55 is not used. Moreover, it is desirable that the hardness of the adherend 55 is 3 degrees to 30 degrees. The adhering body 55 having a hardness of less than 3 degrees is difficult to manufacture, and even if it can be manufactured, it is too soft to maintain its shape. Further, if the hardness is higher than 30 degrees, it is difficult to make the adherent 55 adhere to the curvature of various plastic lenses. By setting the hardness to 3 degrees to 30 degrees, the adhering body 55 easily adheres to the plastic lens, so that the temperature difference is more effectively reduced. A more desirable hardness of the adherend 55 is 5 degrees to 10 degrees. In the present embodiment, the resin body 55 is formed of silicone having a hardness of about 6 degrees.

  It is desirable that the thickness of at least a portion on which the plastic lens is placed (the entire adherence body in the present embodiment) of the attachment body 55 is 1 mm to 10 mm. If the thickness is less than 1 mm, it becomes difficult for the heat of the plastic lens to diffuse into the adhering body 55, so it is difficult to suppress the occurrence of a temperature difference. In addition, when the thickness is thicker than 10 mm, it is difficult to adhere the adherent 55 in accordance with the curvature of the plastic lens. By setting the thickness to 1 mm to 10 mm, the adhering body 55 easily adheres to the plastic lens and effectively suppresses the occurrence of a temperature difference.

  In addition, when the surface of the plastic lens on the attachment body 55 is curved in a spherical shape, the curvature radius of the placement surface (upper surface) of the attachment body 55 on which the plastic lens is placed is It is desirable that it is 50 mm-200 mm. In this case, the adhering body 55 easily adheres to both a plastic lens having a large curvature radius and a plastic lens having a small curvature radius. That is, in this case, a sufficient contact area between the adhering body 55 and the plastic lens is ensured, and the occurrence of a temperature difference is more effectively suppressed.

  Further, in the plan view, it is desirable that the size of the adhering body 55 be larger than the size of the resin body to be heated. In this case, either a resin body (for example, a plus lens or a convex lens) whose temperature on the outer peripheral side is more likely to rise than the inner side, or a resin body (for example, a negative lens or a concave lens) whose temperature is more likely to rise on the inner side than the outer peripheral side. Even when heating is performed, the adhering body 55 adheres to the entire resin body. Therefore, the occurrence of a temperature difference can be suppressed regardless of the shape of the resin body. On the other hand, when the adhering body 55 is too larger than the resin body in plan view, stains on the dye are likely to adhere to the adhering body 55. Therefore, it is more desirable that the size of the adhering body 55 be the same size as the resin body to be heated. However, the size of the attachment 55 can be changed. For example, when the dyeing apparatus 1 heats only the minus lens, the occurrence of a temperature difference is sufficiently suppressed even if the attachment 55 is made smaller than the minus lens and the attachment 55 is attached to the central portion of the minus lens. it can.

  As shown in FIG. 7, the closed chamber front wall 22 is fixed to the front side of the installation portion 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.

  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. In the substrate holding frame 58, two circular openings are formed side by side so as to correspond to the position and size of the cylindrical portion 53 (see FIG. 6) 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 portion of the cylindrical portion 53, the lower surface of the dyeing substrate 57 faces the plastic lens installed on the adherend 55 in a non-contact manner.

  With reference to FIG. 8, the retracting mechanism 60 will be described. The retracting mechanism 60 retracts the dyeing substrate 57 (see FIG. 7) held by the substrate holding frame 58 from the installation unit 50. The retraction mechanism 60 mainly includes two support arms 61, an operation arm 63, a retraction motor 82, and a rotation link 65. The two support arms 61 extend parallel to the front-rear direction. The rear end side of each support arm 61 is rotatably held by the housing 2 (see FIGS. 1 and 2). The operating arm 63 is a substantially bar-shaped member extending in the left-right direction. The left end portion of the operating arm 63 is fixed to the front end portion of the left support arm 61. The right end portion of the operating arm 63 is fixed to the front end portion of the right support arm 61. The operating arm 63 includes a magnet (not shown) at the bottom. When the bottom of the operating arm 63 contacts the base body holding frame 58, the base body holding frame 58 is attracted to the magnet of the operating arm 63.

  The retract motor 82 is installed on the left side of the retract mechanism 60. The rotation link 65 is held in the vicinity of the retracting motor 82 so as to be rotatable about a rotation axis extending in the left-right direction. The rotation link 65 is rotated by the power of the retracting motor 82. A columnar protrusion 66 extending rightward is provided on the outer side of the rotation shaft on the right side surface of the rotation link 65. Further, the left support arm 61 is formed with an engagement long hole 62 extending in the front-rear direction. The width (minor axis) in the end-hand direction of the engagement long hole 62 matches the diameter of the protrusion 66. The protrusion 66 engages with the engagement long hole 62.

  The staining apparatus 1 can rotate the left support arm 61 around the rear end side by driving the retracting motor 82 to rotate the rotation link 65. When the left support arm 61 rotates, the operating arm 63 and the right support arm 61 also rotate. The dyeing apparatus 1 positions the operation arm 63 above the substrate holding frame 58 until the heating of the dye on the dyeing substrate 57 (the vapor deposition step) is completed. When the deposition process is completed, the staining apparatus 1 moves the installation unit 50 (see FIG. 7) forward from the inside of the closed chamber main body 21 (see FIG. 4) by the installation unit back-and-forth movement mechanism 40 (see FIG. 5). . The position of the operating arm 63 is lowered, and the base holding frame 58 is attracted to the magnet at the bottom of the operating arm 63. Next, the position of the operating arm 63 is raised again. As a result, the dyeing substrate 57 held by the substrate holding frame 58 is automatically retracted from the installation unit 50 by the retracting mechanism 60.

  With reference to FIG. 9, the electrical configuration of the staining apparatus 1 will be described. The staining apparatus 1 includes a CPU 70 that controls the staining apparatus 1. The CPU 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. Connected via 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 shown in FIG. 11). 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 drive unit 76 controls driving of the adjustment unit rotation motor 80, the forward / backward movement motor 81, and the retracting motor 82.

  An outline of a method for producing a dyed resin body according to this embodiment will be described. Conventionally, an immersion dyeing method (hereinafter referred to as “immersion method”) is often used as a method for producing a dyed resin body by dyeing a resin body. In the dipping method, dyeing is performed by heating a liquid in which a dye is dispersed and immersing a resin body in the heated liquid. This dipping method has various problems such as a problem that dyeing becomes unstable due to aggregation of dyes, a problem that a large amount of dye is discarded, and a problem that the working environment is bad. There is also a method for dyeing a resin body by heating and sublimating a solid sublimable dye. However, it is difficult to quantitatively fly the solid sublimable dye, and it is also difficult to adjust the color. On the other hand, in the dyeing method according to the present embodiment (hereinafter referred to as “gas phase transfer dyeing method”), a sublimation dye is attached to the plate-like dyeing substrate 57 and the dyeing substrate 57 is applied to the resin body. The dye is transferred (deposited). Next, the resin body is heated to fix the dye to the resin body. Therefore, variations in hue and density are reduced, and the quality of dyeing is stabilized. The dye necessary for dyeing (that is, the dye attached to the dyeing substrate) may be a smaller amount than the dye dispersed in the liquid in the dip dyeing method, and therefore less dye is wasted than in the dip dyeing method. Furthermore, the working environment is also improved compared to the case where the dip dyeing method is performed. In the present embodiment, “fixing” refers to a state in which the dye attached to the resin surface is diffused into the resin at a single molecule level by heat. “Fixing” may also be expressed as dyeing or color development. Further, in the fixing step, the dye itself transferred to the resin body may be heated. Also in this embodiment, the dye itself is heated together with the resin body by the visible light generated by the electromagnetic wave generator 11, and the dye is fixed to the resin body.

  When the resin body is dyed by the gas phase transfer dyeing method, the dye of the dyeing substrate 57 is heated in the vapor deposition step, and the resin body is heated in the fixing step. In the vapor deposition step, in order to deposit the dye accurately while preventing the aggregation of the dye and the like, it is necessary to heat the dye with a vacuum around the resin body. In the fixing process, if a temperature difference occurs in each part of the resin body, the fixing of the dye may be uneven. The effect of discoloration that occurs in the resin body due to heating appears non-uniformly, and may deteriorate in appearance. Therefore, in the conventional vapor phase transfer dyeing method, after the vapor deposition step by electromagnetic wave heating is performed in a substantially vacuum atmosphere, the resin body is moved to the oven, and the fixing step is performed by the oven. By using the oven, the temperature of the resin body rises slowly, so that the occurrence of a temperature difference at each part of the resin body is suppressed.

  However, in the conventional vapor phase transfer dyeing method, an apparatus for performing a vapor deposition process and an oven for performing a fixing process are used together. In this case, a large space is required for installing the two devices, and it is difficult to reduce the cost for introducing the devices. Therefore, for example, it is difficult to carry out the vapor phase transfer dyeing method at a spectacles retail store or the like, and it has not been possible to quickly provide the product to the customer. Further, when the fixing process is executed by the oven, it takes time to move the resin body to the oven, and the rate of temperature rise by the oven is also slow. Therefore, it has been difficult to shorten the time required for the fixing process.

  In order to solve the above problem, it is desirable to use the electromagnetic wave generating portion used for heating the dye in the vapor deposition step for heating the resin body in the fixing step. However, when the resin body is heated by irradiating electromagnetic waves, as described above, a temperature difference may occur in each part of the resin body, and the dyeing quality may deteriorate. In addition, if the fixing step is performed while the atmospheric pressure around the resin body is low, the dye attached to the resin body may be sublimated again, resulting in unstable dyeing quality. According to the technique exemplified in the present embodiment, the above problems can be solved, and a high-quality dyed resin body can be produced in a short time and at a low cost.

  With reference to FIG. 10, the dyeing resin body manufacturing process which concerns on this embodiment 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 substrate (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 the present embodiment, a plastic lens, which is a resin body, is installed on the adherend 55 (see FIG. 6) of the installation unit 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. 7). 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 lowering the air pressure around the resin body and a step of attaching the adhering body 55 to the resin body are 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. During this time, the gas existing between the bottom surface of the resin body and the top surface of the attachment body 55 is sucked, and the attachment body 55 adheres to the bottom surface of the resin body (that is, the surface opposite to the surface on which the dye is deposited). Therefore, in this embodiment, even if the process of pressing the adhering body 55 to the resin body is not performed, the adhering body 55 adheres to the resin body in the process of forming a substantially vacuum space. The adhering body 55 adhering to the resin body does not hinder vapor deposition (that is, adhesion of dye from the dyeing substrate 57 to the resin body surface).

  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 part 50 is moved to the outside of the closed chamber 20 by the installation part back-and-forth movement mechanism 40 (see FIG. 5). The substrate holding frame 58 holding the dyeing substrate 57 is retracted from the installation unit 50 by the retracting mechanism 60 (see FIG. 8). 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 irradiation distribution of electromagnetic waves is appropriately adjusted by the distribution adjusting unit 14 (see FIG. 3). Further, the adhering body 55 adheres to the resin body, and the heat generated locally in a part of the resin body diffuses into the adhering body 55. Therefore, the temperature difference of each part in the resin body hardly occurs. The electromagnetic wave is irradiated to the opposite side (upper surface in this embodiment) of the resin body to the side on which the adherent 55 is attached. Therefore, the electromagnetic wave reaches the resin body without passing through the adhering body 55, and the dye deposited on the upper surface of the resin body is efficiently fixed.

  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. As a result, the temperature of the resin body gradually decreases. 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 addition, the temperature of the resin body is drastically lowered and the possibility of deformation and cracking is also reduced.

  With reference to FIG. 11, the dyeing | staining process which CPU70 of the dyeing | staining apparatus 1 performs is demonstrated. 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 CPU 70 executes the staining process shown in FIG. 11 according to the staining control program. In the dyeing process, steps S3 to S8 in the dyed resin body manufacturing process (see FIG. 10) described above are automatically performed.

  First, it is determined whether or not an opening switching instruction or lens information is input (S21). The opening switching instruction refers to the opening 15 positioned between the electromagnetic wave generator 11 and the installation unit 50 (see FIG. 1) among the plurality of openings 15 formed in the distribution adjusting unit 14 (see FIG. 3). This is an instruction to switch. The instruction for switching the opening 15 may be an instruction for directly specifying the size of the opening 15. The lens information is a parameter of the plastic lens to be dyed. As the parameters, for example, a lens material, a diameter, a power, a refractive index, a height of an upper end surface, a height of a central surface, a shape, and the like can be used. The operator can input an opening switching instruction or lens information to the staining apparatus 1 by operating the touch panel 6. The staining apparatus 1 can also input an opening switching instruction or lens information from another device via a network or the like.

  If neither the opening switching instruction nor the lens information is input (S21: NO), the process proceeds to the determination of S24 as it is. When the opening switching instruction is input (S21: YES), the distribution adjusting unit 14 is rotated by the adjusting unit rotating motor 80 (see FIG. 9), thereby switching the opening 15 (S22). When the lens information is input (S21: YES), the adjustment unit rotating motor 80 is driven so that the opening 15 suitable for heating the lens having the input parameters is used. As an example, in this embodiment, the lens shape (plus lens, minus lens, etc.) is input as lens information. The CPU 70 switches the opening 15 according to the input lens shape. The process proceeds to the determination at S24.

  In the present embodiment, when the opening 15A having a large diameter is used, the intensity distribution of the electromagnetic wave is stronger on the outer side than the central part of the plastic lens. Moreover, when using the opening part 15B with a small diameter, the electromagnetic waves that have passed through the annular opening part 15B overlap at the center part of the plastic lens. As a result, the intensity distribution of electromagnetic waves is stronger at the center than on the outside of the plastic lens. Therefore, when a minus lens is designated as the plastic lens to be dyed, the CPU 70 positions the opening 15 </ b> A having a large diameter between the electromagnetic wave generation unit 11 and the installation unit 50. In this case, each part of the minus lens that is thicker on the outer side than the center part is heated substantially evenly. On the other hand, when a plus lens is designated as the plastic lens to be dyed, the CPU 70 positions the opening 15B having a small diameter between the electromagnetic wave generation unit 11 and the installation unit 50. In this case, each portion of the plus lens whose center portion is thicker than the outside is heated substantially uniformly.

  Next, it is determined whether or not an instruction to start staining has been input (S24). The operator installs the plastic lens and the dyeing substrate 57 in the installation unit 50. Next, the worker inputs a staining start instruction to the staining apparatus 1 by touching a position corresponding to a start button (not shown) displayed on the display 7 of the touch panel 6. If the staining start instruction has not yet been input (S24: NO), the process returns to the determination in S21, and the determinations in S21 and S24 are repeated.

  When an instruction to start staining is input (S24: YES), the forward / backward movement motor 81 (see FIG. 5) is driven and the installation unit 50 is moved rearward, so that the installation unit 50 is moved into the closed chamber 20. It is carried in (S26). As a result, the inside of the closed room 20 is closed by the closed room main body 21, the closed room front wall 22, and the transmission part 25. Next, the gas in the closed chamber 20 is discharged to the outside by the pump 31 (see FIG. 9), so that the atmospheric pressure in the closed chamber 20 is reduced and a substantially vacuum state is obtained (S27). As a result, the adhering body 55 automatically adheres to the plastic lens.

  When the pressure in the closed chamber 20 detected by the pressure sensor 84 (see FIG. 9) becomes equal to or lower than the threshold value and it is determined that the gas discharge is completed, the infrared heater 12 (see FIG. 2) is turned on, and the electromagnetic wave (Infrared rays in the present embodiment) is generated (S28). The electromagnetic wave is irradiated toward the dyeing substrate 57 installed in the installation unit 50. As a result, the sublimable dye attached to the lower surface of the dyeing substrate 57 is heated and sublimated, and is attached (deposited) on the upper surface of the plastic lens. In the process of S28 in this embodiment, electromagnetic waves are irradiated from the infrared heater 12 with the maximum output. As a result, stable deposition is performed in a short time. Moreover, the irradiation time of the electromagnetic wave in vapor deposition is preset. When the irradiation time has elapsed, the infrared heater 12 is turned off (S29). The electromagnetic valve 33 (see FIG. 9) is opened, external gas is introduced into the closed chamber 20, and the atmospheric pressure in the closed chamber 20 is increased to approximately atmospheric pressure (S30).

  Next, the longitudinal motor 81 is driven, and the installation unit 50 is moved to the outside (front) of the closed chamber 20 (S32). After the retracting motor 82 (see FIG. 8) is driven and the base holding frame 58 is attracted to the operating arm 63 of the retracting mechanism 60 by magnetic force, the operating arm 63 is raised. As a result, the dyeing substrate 57 is withdrawn from the position heated by the electromagnetic wave generator 11 (S33). Therefore, the dyeing apparatus 1 can perform dyeing without causing the operator to perform an operation for retracting the dyeing substrate 57. Thereafter, the installation part 50 is carried into the closed chamber 20 again by the installation part back-and-forth movement mechanism 40 (S34).

  Next, the infrared heater 12 is turned on with the atmospheric pressure in the closed chamber 20 being atmospheric pressure or substantially atmospheric pressure, and electromagnetic waves are generated (S36). Since the dyeing substrate 57 is retracted, the electromagnetic wave is directly applied to the plastic lens installed on the attachment 55 of the installation unit 50 to heat the plastic lens. As a result, the dye deposited on the upper surface of the plastic lens is fixed. Since the pressure in the closed chamber 20 is substantially atmospheric pressure, it is unlikely that the dye attached to the plastic lens will sublime again and the dyeing becomes unstable. The intensity distribution of the electromagnetic wave applied to the plastic lens is appropriately adjusted by the distribution adjusting unit 14. Therefore, the temperature rise of each part of the plastic lens is appropriately controlled (so as to be substantially equal). Further, an adhering body 55 is attached to the lower surface of the plastic lens. Therefore, even when the temperature of a part of the plastic lens becomes higher than the temperature of the other part, the heat generated more than the other part diffuses to the adhering body 55. As a result, it is possible to suppress a difference in the temperature increase rate of each part of the resin body.

  In the process of S36 in this embodiment, first, electromagnetic waves are irradiated from the infrared heater 12 with the maximum output. Therefore, the staining apparatus 1 can raise the temperature of the plastic lens in a short time. Next, when the temperature rise of the plastic lens is completed, the CPU 70 adjusts the output of the infrared heater 12 so that the temperature of the plastic lens is maintained. The timing for adjusting the output may be a timing at which the temperature detected by the thermocouple 24 (see FIG. 4) reaches a predetermined temperature, or a timing at which a predetermined time has elapsed from the start of irradiation of electromagnetic waves. The electromagnetic wave irradiation time for fixing is set in advance. Further, the dyeing apparatus 1 may maintain the temperature of the plastic lens by switching the opening 15 during the fixing step (S36). When the irradiation time has elapsed, the infrared heater 12 is turned off (S37). The plastic lens is waited in the closed chamber 20 or the front chamber, and the plastic lens is gradually cooled (S38). When the slow cooling is finished, the installation part 50 is moved to the outside of the housing 2 by the installation part back-and-forth movement mechanism 40 (S39), and the dyeing process is finished. The cooling fan 8 is always driven at least while electromagnetic waves are generated. Therefore, useless heat in the housing 2 is released to the outside by the cooling fan 8.

  In the present embodiment, the fixing process is performed in a state where the atmospheric pressure around the plastic lens (that is, the atmospheric pressure in the closed chamber 20) is an atmospheric pressure. Therefore, the possibility that the dye deposited on the plastic lens sublimates again decreases. However, the atmospheric pressure around the plastic lens at the time of fixing is not limited to atmospheric pressure. For example, the atmospheric pressure around the plastic lens may be higher than atmospheric pressure. Further, the atmospheric pressure around the plastic lens may be set between the atmospheric pressure during vapor deposition and the atmospheric pressure. In other words, the dyeing apparatus 1 can reduce the rate at which the dye sublimates again, as compared with the case where the fixing process is performed at the same pressure as during vapor deposition if the atmospheric pressure during fixation is at least higher than the atmospheric pressure during vapor deposition. it can.

  A first modification of the above embodiment will be described with reference to FIG. In the staining apparatus 1 of the above embodiment, the distribution of electromagnetic waves changes when the distribution adjustment unit 14 rotates and the openings 15A and 15B are switched or when the distribution adjustment unit 14 itself is replaced. On the other hand, in the first modified example shown in FIG. 12, the irradiation distribution of electromagnetic waves changes by adjusting the distance D between the distribution adjusting unit 14 and the plastic lens 88 installed in the installation unit 50.

  As shown in FIG. 12, in the first modification as well, in the same way as in the above embodiment, an annular opening is provided between the electromagnetic wave generating part 11 having an annular electromagnetic wave generating part and the plastic lens 88 that is a resin body. A distribution adjusting unit 14 having 15 is arranged. Furthermore, in the first modified example, a distance adjusting unit 90 for moving (vertically moving) the electromagnetic wave generating unit 11 and the distribution adjusting unit 14 with respect to the installation unit 50 is provided. Various configurations can be employed for the distance adjustment unit 90. In the first modification, a rack and pinion mechanism is employed as the distance adjustment unit 90. The staining apparatus 1 drives the rack and pinion mechanism by rotating a distance adjustment motor (not shown). However, the operator may manually drive the rack and pinion mechanism.

  When the distance D between the distribution adjustment unit 14 and the plastic lens 88 is shortened, the electromagnetic wave beam that has passed through the opening 15 is not diffused so much and is strongly irradiated near the outer periphery of the plastic lens 88. As a result, the temperature increase rate in the vicinity of the outer peripheral portion of the plastic lens 88 is higher than the central temperature increase rate. On the other hand, when the distance D is increased, the beam of electromagnetic waves that has passed through the opening 15 is in a state of spreading when it reaches the plastic lens 88. When the electromagnetic wave beam that has passed through the annular opening 15 diffuses, the diffused electromagnetic wave overlaps at the center of the plastic lens 88. As a result, the rate of temperature rise at the center relative to the vicinity of the outer peripheral portion is higher than when the distance D is short. As described above, the staining apparatus 1 according to the first modified example dynamically changes the intensity distribution of the electromagnetic wave irradiated to the plastic lens 88 by changing the distance between the distribution adjustment unit 14 and the installation unit 50 by the distance adjustment unit 90. Can be changed. Note that the staining apparatus 1 may change the intensity distribution of the electromagnetic wave by changing the distance P between the electromagnetic wave generation unit 11 and the distribution adjustment unit 14. The intensity distribution may be changed by changing both the distance between the electromagnetic wave generation unit 11 and the distribution adjustment unit 14 and the distance between the distribution adjustment unit 14 and the installation unit 50. Further, the distance may be adjusted by moving the installation unit 50 up and down.

  In addition, the staining apparatus 1 of the first modification adjusts the distance D according to the input lens information in S21 and S22 (see FIG. 11). As an example, when lens information indicating that the type of the plastic lens 88 is a minus lens is input, the distance D is made shorter than when lens information indicating a plus lens is input. Therefore, the dyeing device 1 of the first modification can irradiate the plastic lens 88 with electromagnetic waves with an appropriate intensity distribution according to the lens parameters.

  When the output of the electromagnetic wave generation unit 11 is constant, the longer the distance P (not shown) between the electromagnetic wave generation unit 11 and the plastic lens 88 installed in the installation unit 50 is, the longer the plastic lens 88 becomes. The electromagnetic waves that arrive are weakened. Accordingly, the temperature increase rate of the plastic lens 88 changes according to the distance P. In this case, it may be difficult to keep the dyeing quality of the plastic lens 88 constant. The dyeing device 1 of the first modified example controls the output (voltage) of the electromagnetic wave generator 11 according to the distance P so that the rate of temperature increase of the plastic lens 88 becomes substantially equal even if the distance P is changed. . Specifically, when the distance P is increased, the CPU 70 of the staining apparatus 1 controls the output of the electromagnetic wave generator 11 to an output higher than the output before the increase of the distance P (that is, as the distance P becomes longer, Increase the output). Further, when the distance P is decreased, the output of the electromagnetic wave generator 11 is controlled to be equal to or lower than the output before the distance P is decreased (that is, the output is decreased as the distance P is shortened). Therefore, the dyeing device 1 according to the first modification can suppress a difference in the temperature increase rate of the resin body depending on the distance P.

In addition, when adjusting the output of the electromagnetic wave generation part 11 according to the distance P, the specific output adjustment method can be set suitably. For example, the CPU 70 may increase the output in proportion to the distance P. Each time the distance P increases by a certain amount, the output may be increased stepwise. Further, a method of switching the intensity distribution by switching the opening 15 (the method illustrated in the above embodiment) and a method of switching the intensity distribution by switching the distance D (the method illustrated in the first modification) are simultaneously executed. Also good. In this case, the staining apparatus 1 can adjust the intensity distribution of electromagnetic waves more accurately.
[Evaluation test]
The inventor of the present invention performed an evaluation test in order to confirm that the irradiation distribution of electromagnetic waves can be adjusted by the distribution adjusting unit 14 including the opening 15. In this evaluation test, the inventor arranged the opening 15 formed in the distribution adjusting unit 14 between the electromagnetic wave generating unit 11 and the plastic lens 88 as shown in FIG. Next, the inventor fixed the distance between the electromagnetic wave generation unit 11 and the distribution adjustment unit 14 to 20 mm, and the plastic when the distance D between the distribution adjustment unit 14 and the plastic lens 88 is 30 mm, 40 mm, 50 mm, 60 mm, and 70 mm. The temperature of each part in the lens 88 was measured. The timing of temperature measurement is after 300 seconds from the start of heating by electromagnetic waves. The above test was performed on two types of plastic lenses 88 having different shapes.

  Of the portions where the temperature was measured, the A part is the center of the plastic lens 88, the B part is a position 20 mm away from the center, and the C part is a position 35 mm away from the center (that is, near the outer periphery). The two types of plastic lenses 88 have a diameter of about 70 mm, but the thickness of each part differs between the two types of plastic lenses 88. Specifically, in the plastic lens 88 of “CRS-0.00”, the thickness of the A portion is 2.30, the thickness of the B portion is 2.30 mm, and the thickness of the C portion is 2.30 mm. In the plastic lens 88 of “CRS-4.00”, the thickness of the A part is 1.80 mm, the thickness of the B part is 3.45 mm, and the thickness of the C part is 7.25 mm. Even if the distance D between the distribution adjustment unit 14 and the plastic lens 88 is changed, the voltage of the electromagnetic wave generation unit 11 is changed according to the distance D between the distribution adjustment unit 14 and the plastic lens 88 so that the temperature of the plastic lens 88 becomes substantially equal. It was adjusted. The result of the evaluation test is shown in FIG.

  As shown in FIG. 13, regardless of the type of plastic lens 88, the shorter the distance D, the higher the temperature increase rate in the vicinity of the outer peripheral portion than the center temperature increase rate. Further, the longer the distance D, the lower the temperature increase rate in the vicinity of the outer peripheral portion was lower than the central temperature increase rate. This is because the intensity distribution of the electromagnetic wave applied to the plastic lens 88 is determined according to the shape of the opening 15 of the distribution adjustment unit 14, the position of the distribution adjustment unit 14, and the like. Therefore, the staining apparatus 1 can change the intensity distribution of the electromagnetic wave by changing the distance D. Moreover, the intensity distribution of electromagnetic waves can be changed by switching the openings 15A and 15B (see FIG. 3).

  In the plastic lens 88 of “CRS-0.00”, the thickness of each part is constant. On the other hand, in the plastic lens 88 of “CRS-4.00”, since the thickness of the center is thinner than the thickness near the outer peripheral portion, the temperature at the center is more likely to rise than near the outer peripheral portion. Even if the result of the evaluation test is considered, the rate of temperature increase at the center is higher in “CR S-4.00” than in “CR S-0.00”. Therefore, in order to equalize the temperature increase rate of each part in the plastic lens 88 and improve the quality of dyeing, it is desirable to appropriately change the intensity distribution of the electromagnetic wave according to the shape of the plastic lens 88. According to the result of the evaluation test, in “CR S-0.00”, when the distance D is about 48 to 49 mm, it is considered that the temperature increase rate of each part approaches most evenly. Further, in “CR S-4.00”, when the distance D is about 45 mm, it is considered that the temperature increase rate of each part approaches most evenly. However, when only one shape of the plastic lens 88 is dyed, it is not necessary to dynamically change the intensity distribution of the electromagnetic wave. In other words, “adjusting the electromagnetic wave intensity distribution” does not only mean dynamically changing the intensity distribution, but so that an electromagnetic wave of an appropriate intensity is irradiated according to the part of the resin body. It also means that the intensity distribution is adjusted statically. As described above, the method of adjusting the intensity distribution of the electromagnetic wave is not limited to the method of changing the distance D, and a method of switching the openings 15A and 15B can be employed.

  With reference to FIG. 14, the 2nd modification of the said embodiment is demonstrated. The distribution adjusting unit 14 of the above embodiment adjusts the intensity distribution of the electromagnetic wave generated by the electromagnetic wave generating unit 11 through the opening 15. On the other hand, in the second modified example shown in FIG. 14, the staining apparatus 1 has an intensity distribution of the electromagnetic wave irradiated to the plastic lens 88 by the reflection unit 92 that reflects at least a part of the electromagnetic wave generated by the electromagnetic wave generation unit 11. Adjust.

  As shown in FIG. 14, the distribution adjusting unit 94 of the second modified example is provided with a reflecting unit 92 at a position opposite to the plastic lens 88 with respect to the electromagnetic wave generating unit 11 (that is, above the electromagnetic wave generating unit 11). It has been. The surface of the reflecting portion 92 facing the electromagnetic wave generating portion 11 (that is, the lower surface) reflects the electromagnetic wave generated by the electromagnetic wave generating portion 11. In the present embodiment, the lower surface of the electromagnetic wave generator 11 is formed in a spherical shape (concave shape) recessed upward. Accordingly, the electromagnetic wave applied to the reflection unit 92 from the electromagnetic wave generation unit 11 is reflected downward by the reflection unit 92. The beam diameter of the reflected electromagnetic wave gradually decreases as it goes downward. Therefore, the intensity of the electromagnetic wave reflected by the reflecting portion 92 and applied to the plastic lens 88 is higher at the center than at the outside of the plastic lens 88. On the other hand, the intensity of the electromagnetic wave directly directed downward from the electromagnetic wave generator 11 is higher on the outer side than the central part of the plastic lens 88. Therefore, the staining apparatus 1 according to the second modification can appropriately adjust the intensity distribution of the electromagnetic wave applied to the plastic lens 88 by using the reflection unit 92 of the distribution adjustment unit 94. Moreover, the dyeing apparatus 1 of the second modified example can efficiently irradiate the plastic lens 88 with the electromagnetic wave generated by the electromagnetic wave generation unit 11 by using the reflection unit 92.

  Moreover, the dyeing apparatus 1 of the second modified example includes a configuration that changes the distance between the plastic lens 88 and the reflecting portion 92. That is, the staining apparatus 1 according to the second modified example moves at least one of the plastic lens 88 and the reflecting portion 92 up and down. By changing the distance between the plastic lens 88 and the reflecting portion 92, the intensity distribution of the electromagnetic wave reflected by the reflecting portion 92 and applied to the plastic lens 88 changes. Therefore, the staining apparatus 1 according to the second modification can dynamically change the intensity distribution of the electromagnetic wave applied to the plastic lens 88.

  Needless to say, the position and shape of the reflecting portion 92 can be changed as appropriate. For example, the shape of the reflecting portion 92 on the side facing the electromagnetic wave generating portion 11 may be changed to other shapes such as a flat plate shape and a conical shape according to the heating mode to be performed. A reflection unit 92 may be installed on the side of the electromagnetic wave generation unit 11. You may provide the structure switched to the reflection part 92 from which a shape differs.

  The distribution adjusting unit 14 described in the above embodiment and the modification is an example. That is, the configuration for adjusting the intensity distribution of the electromagnetic wave can be changed. For example, the intensity distribution may be adjusted by adjusting the arrangement of a plurality of infrared heaters. Further, the intensity distribution may be adjusted by adjusting the output of each of the plurality of infrared heaters. As an example, when the intensity of the electromagnetic wave applied to the central part of the plastic lens is made stronger than that of the outer peripheral part, an infrared heater may be arranged at the central part of the electromagnetic wave generating part 11 at a higher density than the outer peripheral part. Moreover, you may make the output of the infrared heater arrange | positioned in the center part of an electromagnetic wave generation part higher than the output of the infrared heater arrange | positioned in an outer peripheral part.

  Moreover, in the said embodiment and modification, the case where the plastic lens of a radially uniform shape was heated was illustrated. That is, when the plastic lens is rotated about an axis that passes through the geometric center of the lens and is perpendicular to the lens surface, the plastic lens of the above-described embodiment and the modification is rotationally symmetric with respect to an arbitrary angle. Therefore, the opening 15 is not elliptical but a perfect circle, and the reflecting portion 92 is also a uniform spherical shape. However, the present invention can also be applied to heating a resin body having a radially uneven shape (for example, a toric lens including a cylindrical component). In this case, for example, the staining apparatus 1 may adjust the intensity distribution of the electromagnetic wave irradiated on the resin body by disposing a cylinder lens as a distribution adjusting unit between the electromagnetic wave generating unit 11 and the resin body. In this case, by providing a mechanism for rotating the cylinder lens or a mechanism for moving the cylinder lens, the intensity distribution of the electromagnetic wave can be adjusted more appropriately according to the shape of the resin body. Moreover, when heating the resin body of a radially uneven shape, the shape of the opening 15 of the distribution adjusting unit 14 may be an ellipse. The intensity distribution of the electromagnetic wave may be adjusted by irradiating the electromagnetic wave while changing the positional relationship between the electromagnetic wave generator 11 and the resin body.

  Further, two or more of the plurality of distribution adjustment units described above can be used in combination. For example, the intensity distribution of the electromagnetic wave may be adjusted by using both the opening 15 exemplified in the above embodiment and the reflecting portion 92 exemplified in the second modification. In this case, it is desirable to set both the shape, the arrangement, and the like in consideration of both the intensity distribution adjusted by the opening 15 and the intensity distribution adjusted by the reflecting portion 92. By combining a plurality of distribution adjustment units, the intensity distribution of electromagnetic waves is adjusted more appropriately.

  As described above, the staining apparatus 1 according to the embodiment and the modification adjusts the intensity distribution of the electromagnetic wave irradiated to the resin body by the distribution adjusting units 14 and 94. Therefore, it is possible to irradiate each part of the resin body with an electromagnetic wave having an appropriate intensity. Therefore, the dyeing apparatus 1 can fix the dye by heating the resin body by irradiation of electromagnetic waves while appropriately controlling the temperature rise of each part of the resin body.

  If the fixing process can be appropriately executed by irradiation with electromagnetic waves, various effects can be obtained. For example, the dyeing apparatus 1 can heat the resin body in a shorter time than when using other heating means such as an oven. It is easy to reduce the size of the apparatus body. Moreover, the dyeing | staining apparatus 1 of the said embodiment can perform the process of vapor deposition, and the process of fixing with one electromagnetic wave generation part 11. FIG. Also, a method of controlling the temperature rise of each part of the resin body by scanning an electromagnetic wave beam is conceivable. However, the configuration and control for scanning the electromagnetic wave beam are complicated, and it is difficult to shorten the staining time. On the other hand, the dyeing device 1 of the above embodiment can control the temperature rise of the resin body with a simple configuration and can shorten the dyeing time as compared with the conventional case.

  The distribution adjusting unit 14 of the above embodiment has an opening 15 that allows at least a part of the electromagnetic wave to pass therethrough. In this case, the staining apparatus 1 can easily and appropriately adjust the electromagnetic wave intensity distribution by allowing the electromagnetic wave to pass through the opening 15. Moreover, the opening part 15 of the said embodiment is formed in cyclic | annular form. The staining apparatus 1 allows the electromagnetic wave to pass through the opening 14 of the distribution adjusting unit 14, thereby easily adjusting the intensity of the central part and the intensity of the peripheral part of the irradiated electromagnetic wave beam with a simple configuration. it can.

  In the above embodiment, the generation site for generating the electromagnetic wave in the electromagnetic wave generation unit 11 is formed in an annular shape corresponding to the shape of the opening 15. Therefore, the staining apparatus 1 can efficiently irradiate the resin body with the electromagnetic wave from the opening 15 as compared with the case of using the electromagnetic wave generation part having a generation part of another shape such as a spherical shape or a planar shape.

  The adjustment unit mounting gear 18 of the above embodiment detachably mounts each of the plurality of distribution adjustment units 14 having at least one of the size and shape of the opening 15. Therefore, the operator can appropriately adjust the temperature rise of each part of the resin body by attaching the distribution adjustment unit 14 having the opening 15 suitable for the shape of the resin body to the adjustment unit mounting gear 18. it can.

  A plurality of openings 15A and 15B having different sizes and shapes are formed in the distribution adjusting unit 14 of the above embodiment. In the staining apparatus 1, the distribution adjustment unit 14 is rotated and the posture is switched, so that the openings 15 </ b> A and 15 </ b> B that adjust the intensity distribution of the electromagnetic wave among the plurality of openings 15 </ b> A and 15 </ b> B are switched. Therefore, the operator can easily adjust the temperature rise of each part of the resin body only by switching the posture of the distribution adjusting unit 14. Moreover, the dyeing | staining apparatus 1 of the said embodiment switches the opening part 15 according to the parameter (lens information in the said embodiment) of a resin body. Therefore, the staining apparatus 1 can irradiate the resin body with electromagnetic waves using the appropriate opening 15 according to the resin body without causing the operator to perform many operations.

  The staining apparatus 1 according to the embodiment further includes the closed chamber 20 and the pump 31. The CPU 70 of the dyeing apparatus 1 emits electromagnetic waves toward the dyeing substrate 57 in a state where the dyeing substrate 57 faces the resin body in a non-contact manner and the air pressure in the closed chamber 20 is lowered by the pump 31. Irradiate. As a result, the sublimable dye is heated and deposited on the resin body (S27 to S29, see FIG. 11). In addition, the CPU 70 fixes the dye to the resin body by irradiating the electromagnetic wave generator 11 with an electromagnetic wave on the resin body on which the dye is deposited (S36, see FIG. 11). Therefore, the dyeing apparatus 1 can execute both the vapor deposition process and the fixing process in the gas phase transfer dyeing method. Therefore, the worker can perform gas phase transfer dyeing even in a work place narrower than before. Costs for installing equipment will also decrease. Furthermore, the dyeing apparatus 1 performs the vapor deposition process and the fixing process using the same electromagnetic wave generation unit 11. Accordingly, the cost of the staining apparatus 1 itself is reduced. It is easy to reduce the size of the staining apparatus 1.

  In the above-described embodiment, the CPU 70 executes the fixing step (electromagnetic wave irradiation) in a state where the pressure in the closed chamber 20 is higher than the pressure in the vapor deposition step. Therefore, the possibility that the dye deposited on the surface of the resin body sublimes again during the fixing process is lower than when the fixing process is performed under a low pressure. Therefore, the staining apparatus 1 can perform stable staining.

  In the above embodiment, the electromagnetic wave generation unit 11 is provided outside the closed chamber 20. In the closed chamber 20, a transmission part 25 that transmits electromagnetic waves is provided at a portion between the resin body installed in the installation part 50 and the electromagnetic wave generation part 11. Therefore, the dyeing apparatus 1 can execute both the vapor deposition process and the fixing process without installing the electromagnetic wave generation unit 11 in the closed chamber 20 where the atmospheric pressure is lowered. Therefore, the possibility that a problem occurs in the electromagnetic wave generation unit 11 due to a decrease in atmospheric pressure is reduced. There is no need to employ an electromagnetic wave generator having high resistance to atmospheric pressure.

  The installation part 50 in the above embodiment includes an attachment body mounting part 52 that attaches an attachment body 55 having adhesiveness to the resin body at a portion that contacts the resin body. When the shape of the resin body is not uniform (for example, when the thickness is not constant), there may be a difference in the rate of heat diffusion depending on each part of the resin body. It is difficult for the staining apparatus 1 to appropriately control the temperature of each part when the rate of heat diffusion varies depending on each part. The dyeing apparatus 1 can diffuse the heat of the portion where heat is difficult to diffuse to the adherent body 55 by attaching the adherent body 55 to the resin body. Therefore, the dyeing apparatus 1 can control the temperature of the resin body more appropriately by reducing the influence of the difference in the rate of heat diffusion.

  The staining apparatus 1 of the first modification (see FIG. 12) includes a distance adjustment unit 90 that changes the distance between the distribution adjustment unit 14 and the installation unit 50. The staining apparatus 1 according to the first modification can dynamically change the intensity distribution of the electromagnetic wave irradiated onto the resin body by driving the distance adjusting unit 90. Therefore, the temperature rise of each part of the resin body can be controlled more appropriately. Moreover, the dyeing apparatus 1 of the first modified example changes the distance between the distribution adjusting unit 14 and the installation unit 50 according to the input lens information. Therefore, the electromagnetic wave intensity distribution can be adjusted according to the lens without causing the operator to perform many operations. In addition, the staining apparatus 1 according to the first modification controls the output of the electromagnetic wave generation unit 11 according to the distance between the electromagnetic wave generation unit 11 and the installation unit 50. Therefore, it can suppress that a difference arises in the rate of temperature rise of a resin body according to the distance of electromagnetic wave generation part 11 and a resin body. Therefore, a difference in dyeing quality or the like hardly occurs.

  In addition, the staining apparatus 1 according to the second modification (see FIG. 13) includes a reflection unit 92 in the distribution adjustment unit 94. The reflection unit 92 adjusts the intensity distribution of the electromagnetic wave applied to the resin body by reflecting at least a part of the electromagnetic wave generated by the electromagnetic wave generation unit 11 and changing the propagation direction. Therefore, the staining apparatus 1 of the second modification can appropriately adjust the intensity distribution of electromagnetic waves with a simple configuration. Further, the staining apparatus 1 of the second modified example can dynamically change the intensity distribution by adjusting the distance between the installation unit 50 and the reflection unit 92. By adjusting the distance according to the parameters of the resin body, the resin body can be irradiated with electromagnetic waves with an intensity distribution suitable for the resin body.

  Of course, the present invention is not limited to the above-described embodiment, and various modifications are possible. The staining apparatus 1 according to the embodiment uses the distribution adjustment unit 14 to suppress a difference in the temperature increase rate of each part of the resin body. Therefore, the fixing process can be performed by heating the resin body uniformly, and the quality of dyeing can be improved. However, the application of the distribution adjusting unit 14 is not limited to the case where the resin body is heated uniformly. For example, the distribution adjustment unit 14 can also be applied to a case where the temperature increase rate of a part of the resin body is intentionally higher than other parts.

  In the above embodiment, the case where the substantially disc-shaped plastic lens for spectacles is dyed is illustrated. However, the present invention can also be applied when dyeing a resin body other than a plastic lens. For example, the present invention can be applied to a case where various resin bodies are dyed, such as a cover for a mobile phone, a cover for an automobile light, 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 other words, when the resin body is coated, the “surface of the resin body” may be regarded as the surface of the coated layer, or the resin body itself located under the coated layer You may think of it as the surface of

  The opening 15 in the above embodiment is formed in an annular shape. Therefore, the staining apparatus 1 can adjust the intensity of the central part and the intensity of the peripheral part of the electromagnetic wave beam with a simple configuration. However, it is possible to adjust the intensity distribution of the electromagnetic wave even if an opening having a shape other than the annular shape is used. For example, a circular opening instead of a ring may be used. Further, in the above embodiment, the shape of the electromagnetic wave generation site is also an annular shape corresponding to the shape of the opening 15. Therefore, the staining apparatus 1 can efficiently irradiate the resin body with the electromagnetic waves from the opening 15. However, even if the shape of the electromagnetic wave generation site is changed, if the distribution adjusting unit 14 is used, the intensity distribution of the electromagnetic wave is appropriately adjusted.

  As in the above-described embodiment, it is desirable that the distribution adjusting unit 14 is detachably attached to the staining apparatus 1. However, the distribution adjusting unit 14 that cannot be attached or detached may be used. Even in this case, the intensity distribution of the electromagnetic wave can be changed by using a configuration for switching the plurality of openings 15A and 15B or a configuration for adjusting the distance between the members (see FIG. 12). Moreover, the opening parts 15A and 15B to be used can be switched easily by providing several opening part 15A, 15B in the distribution adjustment part 14 like the said embodiment. However, it is also possible to provide only one opening 15 in the distribution adjusting unit 14.

  In the dyeing apparatus 1 of the above embodiment, the vapor deposition process and the fixing process are both performed by the same electromagnetic wave generator 11. Therefore, effects such as miniaturization of the staining apparatus 1, simplification of the configuration, and cost reduction can be obtained. However, it is possible to adopt the configuration of the distribution adjusting unit 14 even in a staining apparatus in which the heating means used in the vapor deposition process is provided separately from the electromagnetic wave generating unit used in the fixing process. Further, the configuration of the distribution adjusting unit 14 may be adopted in a dyeing apparatus that performs only the fixing process. In addition, for example, even when the electromagnetic wave generation unit 11 is constituted by a plurality of heaters, a part of the plurality of heaters is used at the time of vapor deposition, and all of the plurality of heaters are used at the time of fixing, each of the vapor deposition and fixing is different heating means. The configuration is simplified as compared with the case of executing using. That is, if at least a part of the heating means at the time of vapor deposition and the heating means at the time of fixing are shared, the configuration is simplified.

  In the above embodiment, the same opening 15 is used in the vapor deposition step and the fixing step. However, the dyeing apparatus 1 may change the intensity distribution of the electromagnetic wave by changing the opening 15 or the like in the vapor deposition process and the fixing process. In this case, the dyeing apparatus 1 uses the same electromagnetic wave generation unit 11 to distribute the electromagnetic wave intensity distribution appropriate for heating the dye of the dyeing substrate 57 and the electromagnetic wave intensity distribution appropriate for heating the resin body. Can be realized. Therefore, the dyeing | staining by a gaseous-phase transfer dyeing method can be performed more smoothly.

  The staining apparatus 1 according to the embodiment allows the electromagnetic wave to be transmitted from the outside to the inside of the closed chamber 20 while maintaining the hermeticity in the closed chamber 20 by providing the transmitting portion 25 in the closed chamber 20. Therefore, the dye of 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 sublimate the sublimable dye of the dyeing substrate 57 by heating the iron plate with electromagnetic waves while 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.

  The installation unit 50 of the above embodiment includes an attachment body mounting portion 52 that mounts the attachment body 55. Therefore, the dyeing apparatus 1 can suppress the occurrence of a temperature difference in each part of the resin body by the attached body 55 attached to the resin body. However, the staining apparatus 1 can also control the rate of temperature increase using only the distribution adjustment unit 14 without using the attachment body mounting unit 52. Further, the operator may install the resin body to which the adhesion body 55 is attached in the installation unit 50 after the adhesion body 55 is attached to the resin body in advance.

  The dyeing apparatus 1 of the above-described embodiment includes an adjustment unit rotating motor 80 for switching the opening 15 to be used. Therefore, it is not necessary for the operator himself to switch the opening 15. However, the electromagnetic wave intensity distribution can be dynamically changed even when the operator manually switches the opening 15. In the embodiment and the modification, the electromagnetic wave generator 11 is positioned above the resin body and the dyeing substrate 57, and the resin body and the dyeing substrate 57 are irradiated with electromagnetic waves from above. However, the positional relationship of various configurations may be changed. For example, it is also possible to irradiate electromagnetic waves from below, on the side, and obliquely from the resin body and the dyeing substrate.
