Description

[Technical Field]

[0001] The present disclosure relates to a transfer device that transfers a dye from a substrate to which the dye is attached to a resin body in order to dye the resin body, and a dyeing system that includes the transfer device. [Background technology]

[0002] Various techniques have been proposed for dyeing resin bodies such as plastic lenses. For example, in a dyeing method known as the dip dyeing method, the resin body is dyed by immersing it in a dye solution. However, with the dip dyeing method, it is difficult to maintain a good working environment, and it is also difficult to dye some resin bodies (e.g., lenses with a high refractive index).

[0003] Therefore, a technology has been proposed for dyeing a resin body by transferring a dye to the surface of the resin body and heating the resin body with the dye attached. For example, in the dyeing method described in Patent Document 1, an ink containing a sublimable dye is applied (printed) to a substrate by a printing device (inkjet printer). Next, a transfer step is performed in which the dye is transferred to the resin body by sublimating the sublimable dye applied to the substrate while the resin body and the substrate are arranged in a vacuum without contact. After that, a fixation step is performed in which the resin body is heated to fix the dye to the resin body.

[0004] Furthermore, a technique has been proposed in which part of the surface of a resin body is left undyed while other areas are dyed. For example, in the dyeing method described in Patent Document 2, in a fixing step performed after the transfer step, infrared rays are irradiated onto the resin body while the areas of the resin body to which the dye has not been transferred (i.e., the undyed areas not to be dyed) are covered with a shielding means. This prevents the colorless and transparent areas of the resin body from turning yellow due to heating. [Prior art documents] [Patent documents]

[0006] In the method described in Patent Document 2, even if the non-dyed areas of the resin body are shielded during the fixing process, if the dye has already adhered to the non-dyed areas, heat may be conducted from the dyed areas to the non-dyed areas, potentially causing the dye to be fixed in the non-dyed areas. Furthermore, if only the non-dyed areas of the resin body are shielded, the temperature difference between the dyed and non-dyed areas may cause distortion of the resin body. Therefore, a technology that allows for more appropriate partial dyeing of resin bodies is desired.

[0007] A typical object of the present disclosure is to provide a transfer device and a dyeing system that can appropriately perform partial dyeing of a resin body. [Means for solving the problem]

[0008] A transfer device provided by a typical embodiment of the present disclosure is a transfer device that transfers a sublimable dye from a substrate having the dye adhered thereto to a resin body to be dyed, the transfer device comprising: a closed chamber setting unit that sets the resin body, transported from outside, inside a closed chamber in a state where the resin body faces the substrate without contacting the substrate; an electromagnetic wave generating unit that generates electromagnetic waves for heating the dye adhered to the substrate; a mask setting unit that sets a mask that shields a part of the space from the electromagnetic wave generating unit to the resin body; an air pressure control unit that controls the air pressure in the closed chamber in which the substrate and the resin body are set; and a controller that controls control of the transfer device, and when performing partial dyeing in which the dyeing state is changed between a dyed region and a non-dyed region, the controller performs a partial transfer step in which the dye on the substrate is transferred to the resin body by setting a mask using the mask setting unit to shield the non-dyed region from the electromagnetic wave generating unit and heating the dye on the substrate using the electromagnetic wave generating unit while reducing the air pressure in the closed chamber using the air pressure control unit. The mask setting unit sets the mask between the electromagnetic wave generating unit and the base body in the space from the electromagnetic wave generating unit to the resin body. .

[0009] A dyeing system provided by a typical embodiment of the present disclosure includes the transfer device and a dye fixing device that fixes the dye to the resin body by heating the resin body to which the dye has been transferred by the transfer device. Equipped with

[0010] According to the transfer device and dyeing system of the present disclosure, partial dyeing of a resin body can be carried out appropriately. [Brief explanation of the drawings]

[0012] <Summary> The transfer device exemplified in the present disclosure transfers (adheres) the dye from a substrate having a sublimable dye attached thereto to a resin body to be dyed. The transfer device of the present disclosure includes a closed chamber setting unit, an electromagnetic wave generating unit, a mask setting unit, an air pressure control unit, and a controller. The closed chamber setting unit sets the substrate and resin body, transported from the outside, inside the closed chamber. The electromagnetic wave generating unit generates electromagnetic waves for heating the dye attached to the substrate. The mask setting unit shields a portion of the space from the electromagnetic wave generating unit to the resin body. The air pressure control unit controls the air pressure inside the closed chamber in which the substrate and resin body are set. When performing partial dyeing, which changes the dyeing state between a dyed region and a non-dyed region, the controller sets a mask using the mask setting unit to shield the non-dyed region from the electromagnetic wave generating unit, and reduces the air pressure inside the closed chamber using the air pressure control unit. In this state, the controller performs a partial transfer process in which the dye on the substrate is heated by the electromagnetic wave generating unit to transfer the dye to the resin body.

[0013] According to the transfer device of the present disclosure, when performing partial dyeing, the dye transfer process is performed with the mask setting unit automatically shielding the non-dyed areas of the resin body from the electromagnetic wave generating unit. As a result, the possibility of unintentionally transferring dye to non-dyed areas that are not intended to be dyed is appropriately reduced. Therefore, even without using a mask or the like in the fixing process, only the areas to be dyed are more likely to be appropriately dyed, and distortion of the resin body due to temperature differences is less likely to occur. As a result, the resin body is dyed more appropriately.

[0014] The electromagnetic wave generator may be provided inside the closed chamber. When the electromagnetic wave generator is provided outside the closed chamber, the portion of the closed chamber located between the electromagnetic wave generator and the base may be made of a material that is capable of transmitting electromagnetic waves while sealing the internal space.

[0015] Partial dyeing may include gradation dyeing, in which the dye density changes continuously from the dyed region to the non-dyed region. Gradient dyeing is difficult because the dye density decreases from the dyed region to the non-dyed region while the non-dyed region is not dyed. However, by applying the technology of the present disclosure, the possibility of the non-dyed region being dyed is appropriately reduced. Therefore, even gradation dyeing, which is difficult, can be performed appropriately.

[0016] However, partial dyeing may include dyeing other than gradation dyeing. For example, partial dyeing may include a dyeing method in which a dyed area is dyed at a uniform density without dyeing a non-dyed area. Furthermore, special partial dyeing may be performed by making the shape of the dyed or non-dyed area linear, for example.

[0017] The mask setting unit may shield the non-dyed region of the resin body from the electromagnetic wave generating unit by setting a mask between the electromagnetic wave generating unit and the substrate in the space from the electromagnetic wave generating unit to the resin body. In the transfer process, dye attached to the substrate is sublimated and transferred to the resin body. Therefore, if a mask is set between the substrate and the resin body, the sublimated dye also adheres to the mask. If a dye-adhered mask is used multiple times in the transfer process, the dye attached to the mask may also be transferred to the resin body, resulting in a decrease in dyeing quality. Therefore, masks with dye adhering thereto must be frequently cleaned or replaced. Furthermore, even when using a mask to shield the non-dyed region of the resin body in the fixing process, the dye heated during fixing often sublimes again and adheres to the mask. In contrast, setting a mask between the electromagnetic wave generating unit and the substrate makes it difficult for the sublimated dye to adhere to the mask. Furthermore, when transferring dye to a resin body by vapor-phase transfer, it is important to maintain an appropriate distance between the substrate and the resin body. When a mask is set between the substrate and the resin body, the distance between the substrate and the resin body may change depending on whether or not the mask is present, but when a mask is set between the electromagnetic wave generator and the substrate, the distance between the substrate and the resin body does not change, so the dye transfer process can be carried out more appropriately.

[0018] The electromagnetic wave generating unit may irradiate electromagnetic waves from above the substrate downward. The mask setting unit may set the mask by placing the mask on the substrate from above. When the electromagnetic wave generating unit irradiates electromagnetic waves from above the substrate downward, the dye sublimated from the substrate descends by gravity and is appropriately deposited on the resin body located below the substrate. Furthermore, the mask can be easily set by simply placing it on the substrate from above. The set mask shields the portion of the substrate that is projected onto the non-dyed region of the resin body when viewed from the electromagnetic wave generating unit, so that the portion that is projected onto the non-dyed region is not heated. As a result, transfer of the dye to the non-dyed region of the resin body is appropriately suppressed. Therefore, more appropriate partial dyeing is performed.

[0019] The mask setting unit may shield the electromagnetic wave generating unit from the non-dyed region of the resin body by setting a mask between the base and the resin body in the space from the electromagnetic wave generating unit to the resin body. In this case, the mask blocks the sublimated dye as it moves from the base to the non-dyed region of the resin body. Therefore, the dye is appropriately prevented from transferring to the non-dyed region.

[0020] The transfer device may further include a reading unit that reads information about the resin object to be dyed. The controller may control whether or not to set a mask using the mask setting unit, depending on information indicating whether the resin object is to be subjected to partial dyeing, among the information read by the reading unit. That is, the controller may set a mask using the mask setting unit when it is determined from the information read by the reading unit that the resin object is to be subjected to partial dyeing. The controller may not need to set a mask when it is determined from the information read by the reading unit that the resin object is not to be subjected to partial dyeing. In this case, an appropriate transfer process depending on whether or not partial dyeing is to be performed is performed for each resin object to be dyed.

[0021] The reading unit may include an identifier reading unit that reads an identifier provided for each transport unit. The transport unit is a unit that transports and dyes the resin body. For example, the transport unit may include a dyeing tray and a resin body placed on the dyeing tray. The control unit may acquire information corresponding to the identifier read by the identifier reading unit from a database that stores information about the resin body for each transport unit. In this case, even if the order of multiple transport units changes, for example, the control unit can appropriately grasp information about the resin body of each transport unit. Note that the identifier may be provided, for example, on the dyeing tray on which the resin body is placed, or on a substrate used in the transfer process.

[0022] The reader may also include a tag reader that reads information from a writable tag attached to the transport unit. In this case, by storing information indicating whether or not gradation dyeing is to be performed in the tag in advance, the controller can properly grasp the information about the resin body of each transport unit even when, for example, the order of the transport units is changed.

[0023] In other words, the controller may acquire information (discrimination information) for determining whether or not partial staining is to be performed, and determine whether or not to set a mask based on the acquired information. The discrimination information is not limited to information read by the reading unit (i.e., information read by the reading unit indicating whether or not the resin body is to be subjected to partial staining). For example, a user may input an instruction to perform partial staining as discrimination information by operating an operation unit or the like. The controller may set a mask when an instruction to perform partial staining is input. Furthermore, a mode in which partial staining is performed and a mode in which partial staining is not performed may be switched in accordance with an instruction from the user, etc. The controller may determine whether or not to set a mask depending on the mode at that time.

[0024] The blocking chamber setting unit may set a dyeing tray, on which a resin body and a base body are placed facing each other without contacting each other, inside the blocking chamber as a dyeing unit. The mask setting unit may set a mask on the dyeing tray. In this case, an appropriate mask is set for each transport unit that is a dyeing unit.

[0025] The dyeing unit refers to the unit of resin body and accessories when performing at least each transfer process. In this embodiment, at least the dyeing tray and the resin body placed on the dyeing tray are included in the dyeing unit. In the transfer process, the dyeing tray, resin body, and base body are the dyeing unit. In this embodiment, the dyeing tray on which the resin body is placed is transported as a single unit by a transport device (details of which will be described later).

[0026] The staining tray may include a substrate placing section and a positioning section. A substrate is placed on the substrate placing section. The positioning section positions the substrate placed on the substrate placing section. The mask setting section may fix the position of the mask on the staining tray by setting the mask in accordance with the positioning section of the staining tray. In this case, the relative positions of the resin body, the substrate, and the mask are fixed to appropriate positions by the positioning section. This further improves the quality of partial staining.

[0027] The resin body may be a lens used for eyeglasses. Two lenses may be placed on the staining tray. One mask part may include two mask parts used for each of the two lenses placed on the staining tray. In this case, simply placing the mask on the staining tray automatically determines not only the relative position of the mask with respect to each lens, but also the angle (orientation) of each mask part with respect to each lens. This allows for more appropriate partial staining.

[0028] The controller may execute a mask removing step and a mask mounting step when an instruction to replace the mask used in the partial transfer step is input. In the mask removing step, the controller causes the mask setting unit to set a mask on the staining tray, and then transports the staining tray with the mask set to the outside. In the mask mounting step, the controller causes the mask setting unit to hold the mask from the staining tray that has been transported from the outside with a new mask set. In this case, the mask is properly replaced without the operator having to replace the mask themselves, simply by transporting the staining tray with the new mask set to the transfer device.

[0029] The transfer method exemplified in the present disclosure is a method for transferring a sublimable dye from a substrate to which the dye is attached to a resin body to be dyed. The transfer method of the present disclosure includes a mask setting step and a transfer step. In the mask setting step, when performing partial dyeing in which the dyed state is changed between dyed and non-dyed regions, a mask is set to block a portion of the space leading from an electromagnetic wave generator for heating the dye to the resin body to be dyed. In the transfer step, the air pressure in a closed chamber in which the substrate, resin body, and mask are set is reduced, and the dye on the substrate is heated by the electromagnetic wave generator, thereby transferring the dye to the resin body. In this case, as described above, partial dyeing of the resin body is more appropriately performed.

[0030] The transfer method may be performed by an operator performing at least some of the steps that can be performed by the transfer device. For example, the mask setting step may be performed by an operator. Also, the step of setting the resin body inside the closed chamber may be performed by an operator.

[0031] In a transfer process in which at least a portion of the process is performed by an operator, steps similar to those performed by a transfer device may be performed. For example, in the mask setting process, a mask may be set between the electromagnetic wave generator and the base body in the space from the electromagnetic wave generator to the resin body. In this case, as described above, the sublimated dye is less likely to adhere to the mask, and the distance between the base body and the resin body does not change. Therefore, partial dyeing is performed more appropriately. Furthermore, the electromagnetic wave generator may irradiate electromagnetic waves from above the base body downward. In the mask setting process, the mask may be set by placing it on the base body from above. In this case, the mask is set more easily and appropriately.

[0032] The dyeing system exemplified in the present disclosure includes the above-described transfer device and dye fixing device, and in this case, as described above, the partial dyeing of the resin body is appropriately performed.

[0033] The dye fixing device may include a laser light source that emits laser light and a scanning unit that scans the laser light emitted from the laser light source, and fix the dye to the resin body by irradiating the resin body with the laser light. In this case, the surface temperature of the resin body is raised by the laser light, thereby fixing the dye to the resin body. Therefore, compared to cases where the temperature of not only the surface but also the inside of the resin body is likely to rise (for example, when fixing the dye using an oven, etc.), yellowing of the resin body due to heating (discoloration to yellow) is less likely to occur. Therefore, even without using a mask or the like in the fixing process, yellowing is suppressed and only the area to be dyed can be properly dyed.

[0034] <Embodiment> A typical embodiment of the present disclosure will be described below with reference to the drawings. A dyeing system 1 automatically and continuously dyes a resin object. In this embodiment, the resin object to be dyed is a plastic lens L used in eyeglasses (see FIG. 2, etc.). However, at least a portion of the techniques exemplified in this disclosure can also be applied to dyeing resin objects other than lenses L. For example, at least a portion of the techniques exemplified in this disclosure can be applied to dyeing various resin objects, such as goggles, mobile phone covers, light covers, accessories, toys, films (e.g., having a thickness of 400 μm or less), and boards (e.g., having a thickness of 400 μm or more). The resin objects to be dyed also include resin objects attached to a different material (e.g., wood or glass). Furthermore, the dyeing system 1 of this embodiment dyes multiple resin objects while continuously transporting them. However, at least a portion of the techniques exemplified in this disclosure can also be employed in a dyeing system that transports and dyes resin objects one set at a time.

[0035] (System Configuration) The system configuration of a dyeing system 1 of this embodiment will be described briefly with reference to Fig. 1. The dyeing system 1 of this embodiment includes a conveying device 10, a printing device 30, a transfer device 40, a dye fixing device 50, a color measurement device 60, and a control device 70.

[0036] The conveying device 10 conveys dyeing trays 80 (see FIG. 2) on which lenses L, which are resin bodies, are placed to each device in the dyeing system 1. In detail, the conveying device 10 of this embodiment conveys multiple dyeing trays 80 continuously throughout the dyeing system 1. The conveying device 10 of this embodiment conveys the dyeing trays 80 in the order of the printing device 30, the transfer device 40, the dye fixing device 50, and the color measurement device 60 (that is, from left to right in FIG. 1).

[0037] The printing device 30 prints dye (in this embodiment, ink containing dye) onto a sheet-like substrate. In this embodiment, the substrate is made of paper or a metallic film (made of aluminum in this embodiment) of appropriate hardness. However, other materials such as glass, heat-resistant resin, and ceramic can also be used for the substrate. In the dyeing system 1 of this embodiment, to properly transfer the dye to the lens L while preventing the dye from coagulating, the dye on the substrate is heated in a vacuum (including near-vacuum) environment, with the substrate and the lens L facing each other at a distance, to transfer (deposit) the dye onto the surface of the lens L (the dyeing method in this embodiment is referred to as a vapor-phase transfer dyeing method). Therefore, the printing device 30 is an inkjet printer that prints ink containing a sublimation dye onto the substrate. The printing device 30 performs printing based on print data created by a control device 70, which is an information processing device (in this embodiment, a personal computer (hereinafter referred to as a "PC")). As a result, an appropriate amount of ink (dye) is deposited at the appropriate position on the substrate. It is also easy to create dye-coated substrates for gradation dyeing.

[0038] The configuration of the printing device 30 can be changed. For example, the printing device may be a laser printer. In this case, the toner may contain a sublimable dye. Also, instead of the printing device 30, the dye may be applied to the substrate by a dispenser (a device for applying a fixed amount of liquid), a roller, or the like.

[0039] The transfer device 40 transfers the dye adhered to the substrate to the lens L while the substrate is facing the lens L. As described above, in this embodiment, the dye is transferred from the substrate to the lens L by a vapor phase transfer method. The transfer device 40 will be described in detail later.

[0040] The dye fixing device 50 heats the lens L to which the dye has been transferred by the transfer device 40, thereby fixing the dye attached to the surface of the lens L to the resin body. The dye fixing device 50 of this embodiment heats the lens L by irradiating the lens L with laser light, which is an electromagnetic wave. Specifically, the dye fixing device 50 of this embodiment includes a laser light source 51 and a scanning unit 52. The laser light source 51 emits laser light for heating the surface of the lens L to which the dye has been transferred. The scanning unit 52 scans the laser light emitted from the laser light source 51, thereby irradiating a two-dimensional area on the surface of the lens L with the laser light. As a result, the temperature of the surface of the lens L is increased by the laser light, and the dye diffuses and fixes inside the lens L. Therefore, yellowing of the lens L due to heating is less likely to occur compared to cases where the temperature of not only the surface but also the interior of the lens L is likely to rise (for example, when the dye is fixed using an oven, etc.). Therefore, in the fixing process, yellowing of the non-dyed area (transparent area) of the lens L is suppressed even if the non-dyed area of ​​the lens L is not shielded with a mask. However, a device (such as an oven) that irradiates the lens L with electromagnetic waves other than laser light may also be used as the dye fixing device.

[0041] The color measurement device 60 is used to measure color information of the lens L on which the dye has been fixed by the dye fixing device 50. The measured color information is used to check the quality of the dyeing, etc.

[0042] The control device 70 controls various operations in the dyeing system 1. The control device 70 can be any of various information processing devices (for example, at least one of a PC, a server, and a mobile terminal). The control device 70 includes a controller (for example, a CPU) 71 that controls the operations and a database 72 that stores various data. The configuration of the control device 70 can also be changed. First, multiple devices may work together to function as the control device 70. For example, the control device that controls various operations in the dyeing system 1 and the control device that includes the database 72 may be separate devices. Furthermore, controllers of multiple devices may work together to execute various controls in the dyeing system 1. For example, at least one of the conveying device 10, the printing device 30, the transfer device 40, the dye fixing device 50, and the color measurement device 60 often includes a controller. In this case, the controllers of the multiple devices may work together to control the dyeing system 1.

[0043] The staining system 1 includes a reading unit 2 that reads information about the lens L to be stained for each unit to be transported (including a staining tray 80 and the lens L placed on the staining tray 80). As an example, the reading unit 2 in this embodiment is an identifier reading unit that reads an identifier provided for each unit to be transported (for example, each staining tray 80). The identifier read by the reading unit 2 identifies the transport unit. By identifying the transport unit, information about the lens L included in the transport unit (for example, information indicating whether the lens L is a lens to be subjected to partial staining) is acquired. Note that partial staining is a staining method in which the staining state changes between a stained area and a non-stained area. In this embodiment, as one type of partial staining, gradation staining in which the staining density continuously decreases from the stained area to the non-stained area is illustrated as an example.

[0044] The reading unit 2 in this embodiment is an identifier reader (for example, a QR code (registered trademark) reader, a barcode reader, an identification hole reader, etc.) that corresponds to the identifier being used. The reading unit 2 may also be a tag reading unit that reads information from a tag to which information can be written (for example, an IC tag, etc.). In this case, information indicating whether or not the lens is to be subjected to partial dyeing may be stored in the tag. In this embodiment, of the multiple devices that make up the staining system 1, the reading unit 2 is provided in at least the transfer device 40. However, a reading unit may also be provided in a part of the staining system 1 other than the transfer device 40. Furthermore, information indicating whether or not the lens is to be subjected to partial dyeing may be obtained by a reading unit provided in a part other than the transfer device 40.

[0045] The dyeing system 1 may include at least the transfer device 40 among the conveying device 10, the printing device 30, the transfer device 40, the dye fixing device 50, the color measurement device 60, and the control device 70. In this case, the dyeing system 1 can appropriately transfer the dye attached to the substrate S to the lens L and then dye the lens L (details will be described later). Furthermore, the dyeing system 1 may include at least the transfer device 40 and the dye fixing device 50 among the conveying device 10, the printing device 30, the transfer device 40, the dye fixing device 50, the color measurement device 60, and the control device 70. In this case, the dyeing system 1 can transfer (adhere) the dye from the substrate S to the lens L and then appropriately fix the dye attached to the lens L.

[0046] (dyeing tray) The staining tray 80 used in the staining system 1 of this embodiment will be described with reference to FIG. 2. FIG. 2 is a perspective view of the staining tray 80 on which two lenses L are set (placed) and no substrate is set. The staining tray 80 of this embodiment includes a tray main body 81, a mounting frame 89, and a spacer 87. A resin body to be stained (the lens L in this embodiment) is placed on the mounting frame 89. The mounting frame 89 of this embodiment is formed in a ring shape with an outer diameter slightly larger than that of the lens L. The spacer 87 extends upward in a tubular (cylindrical) shape from the outer periphery of the mounting frame 89 at a position on which the lens L is placed. The tray main body 81 is formed with a mounting portion 82. The mounting frame 89 and the spacer 87 are detachably mounted to the mounting portion 82. In this embodiment, two mounting portions 82 are formed on one tray main body 81. Therefore, a pair of lenses (left and right) used for one pair of spectacles are dyed while placed on one staining tray 80.

[0047] A substrate mounting section 85 on which a sheet-like substrate to which sublimation dye adheres is placed is formed on the outer side of the tray main body 81 above the mounting section 82. By placing the substrate on the substrate mounting section 85, the sublimation dye adhered to the substrate faces the lens L placed on the mounting frame 89 without contacting it. Therefore, the dye is appropriately transferred to the resin body.

[0048] The tray main body 81 is provided with protrusions 84 at positions outside the mounting portions 82 (more specifically, outside the substrate mounting portions 85), protruding above the mounting surface of the substrate mounting portions 85 on which the substrate is mounted. The substrate in this embodiment is shaped like a rectangular sheet that covers both mounting portions 82. In this embodiment, multiple (eight) protrusions 84 are formed at positions along the outer periphery of the substrate when it is mounted in an appropriate position on the staining tray 80 (i.e., when it is properly mounted on the substrate mounting portions 85). Therefore, by placing the substrate in an area (substrate mounting portion 85) surrounded by the multiple protrusions 84, the substrate is properly positioned relative to the lens L. This also reduces the possibility that the position of the mounted substrate will be misaligned relative to the lens L. In other words, at least some of the multiple protrusions 84 in this embodiment function as positioning portions that position the substrate relative to the lens L.

[0049] (Outline of the device) Referring to FIG. 3, a schematic description will be given of a portion of the device configuration of the conveying device 10, the transfer device 40, and the dye fixing device 50. As shown in FIG. 3, the conveying device 10 of this embodiment conveys multiple conveying units U continuously from the upstream side (the left side of FIG. 3) to the downstream side (the right side of FIG. 3) in the conveying direction. The transfer device 40 is provided upstream of the dye fixing device 50 in the conveying direction. The conveying unit U is first conveyed to the transfer device 40 with the lens L and the substrate S placed thereon. More specifically, the conveying device 10 conveys the conveying unit U to the front of the transfer device 40, and then lifts the conveying unit U using a transfer section 11, thereby transferring the conveying unit U to the transfer device 40. The transfer device 40 sets the transferred conveying unit U inside and transfers the dye from the substrate S to the lens L (details will be described later). When the transfer process is completed, the transfer device 40 returns the conveying unit U to the transfer section 11. Next, the transport device 10 transports the transport unit U, which has been returned from the transfer device 40, to the front of the dye fixing device 50. The dye fixing device 50 fixes the dye on the lens L of the transported transport unit U. Once the fixing process is complete, the transport device 10 transports the transport unit U further downstream.

[0050] (Transfer device) The transfer device 40 will be described with reference to Figures 4 to 9. Figure 4 is a perspective view of the transfer device 40, seen from diagonally forward right, with the closed chamber bottom 440 (described later) moved to the rear (in this embodiment, a mask attachment / detachment position where the mask M is attached and held by the mask setting unit 460). The lower left side of Figure 4 is the front of the transfer device 40, the upper right side of Figure 4 is the rear of the transfer device 40, the upper left side of Figure 4 is the left side of the transfer device 40, and the lower right side of Figure 4 is the right side of the transfer device 40. The mask M (described later) is omitted from Figure 5.

[0051] As shown in FIG. 4, the transfer device 40 of this embodiment includes a base 401, electromagnetic wave passing units 410R and 410L, an electromagnetic wave generating unit 420, a closed chamber setting unit 430, and an air pressure control unit 450. The base 401 supports the transfer device 40. The electromagnetic wave passing units 410R and 410L pass the electromagnetic waves generated by the electromagnetic wave generating unit 420 to the substrate S disposed in a closed chamber C (see FIG. 5), which will be described later. The electromagnetic wave generating unit 420 generates electromagnetic waves for heating the dye adhered to the substrate S. The closed chamber setting unit 430, together with the base 401 and other components, forms the closed chamber C. In other words, the interior of the closed chamber C is an enclosed space surrounded by the closed chamber setting unit 430 and the base 401 and other components. The closed chamber setting unit 430 sets the transport unit U, delivered from the delivery unit 11 (see FIG. 3) of the transport device 10, inside the closed chamber C. The air pressure control unit 450 varies the air pressure inside the closed chamber C. The mask setting unit 460 sets a mask that shields part of the space from the electromagnetic wave generation unit 420 to the lens L of the transport unit U set inside the closed chamber C.

[0052] The base 401 includes a bottom 402, a right column 403R, a left column 403L, and a base 404. The bottom 402 is placed on an installation location and supports the entire transfer device 40. The right column 403R extends upward from the right end of the bottom 402. The left column 403L extends upward from the left end of the bottom 402. The base 404 is fixed to the upper end of the right column 403R and the upper end of the left column 403L. Therefore, when the base 401 is viewed from the front-to-rear direction, a rectangular opening is formed in the base 401. The base 404 is a substantially plate-shaped member with sufficient strength. Openings are formed in the base 404 at positions facing each of the two lenses L that are set in the blocking chamber C by the blocking chamber setting unit 430.

[0053] The electromagnetic wave passing portions 410R, 410L are cylindrical members and are provided between the electromagnetic wave generating portion 420 and each of two openings formed in the base portion 404. As shown in Fig. 5, the electromagnetic wave generating portion 420 includes therein generation sources (halogen heaters in this embodiment) 421R, 421L that generate electromagnetic waves. The generation source 421R is disposed on the axis of the cylindrical electromagnetic wave passing portion 410R. Similarly, the generation source 421L is disposed on the axis of the cylindrical electromagnetic wave passing portion 410L.

[0054] FIG. 6 is a perspective view of the closed chamber set section 430, seen from the diagonally front right. As shown in FIG. 6, the closed chamber set section 430 includes a base 431, a closed chamber bottom 440, a front-rear moving section 432, a vertical moving section 433, and guide poles 434R and 434L (only guide pole 434R is shown in FIG. 6). The base 431 is a substantially plate-shaped member and serves as the base of the closed chamber set section 430. As shown in FIG. 4, the base 431 is disposed inside the rectangular opening of the platform 401. As shown in FIG. 6, the closed chamber bottom 440 is a substantially plate-shaped member having sufficient strength. A transport unit mounting section 441 is formed on the upper surface of the closed chamber bottom 440, on which a transport unit U (see FIG. 3, etc.) including the substrate S is mounted. The transport unit mounting section 441 of this embodiment has projections and depressions that match the shape of the staining tray 80 (see FIGS. 2 and 3).

[0055] Closed chamber bottom 440 is pressed upward from below against base 404 (see FIG. 4) of platform 401, thereby closing the bottom surface of closed chamber C (see FIG. 5). As shown in FIG. 6, a tray pressing portion 442 and a seal portion 443 are provided on the upper surface of closed chamber bottom 440.

[0056] The tray pressing portions 442 protrude upward from each of a plurality of positions on the transport unit mounting portion 441 (in this embodiment, the four corners of the transport unit mounting portion 441) and are biased upward by biasing members (e.g., springs, etc.). When the closed chamber bottom 440 is pressed upward against the base 404, the dyeing tray 80 of the transport unit U is pressed into the closed chamber C by the plurality of tray pressing portions 442. As a result, the dye heated by the electromagnetic waves and sublimated from the substrate S is less likely to leak out of the mounting frame 89 and spacer 87 (see FIG. 2) of the dyeing tray 80.

[0057] The seal portion 443 is disposed so as to cover the outer periphery of the transport unit mounting portion 441 in an annular shape without any gaps. The seal portion 443 protrudes slightly above the upper surface of the transport unit mounting portion 441. The seal portion 443 is formed from a material that can withstand high temperatures and pressure changes and has appropriate elasticity. Therefore, when the closed chamber bottom 440 is pressed upward against the base 404, the seal portion 443 is pressed against the bottom surface of the base 404 and deforms, improving the airtightness of the closed chamber C (see FIG. 5).

[0058] Front-to-back movement unit 432 is an actuator that moves closed chamber bottom 440 in the front-to-back direction. Vertical movement unit 433 is an actuator that moves closed chamber bottom 440 in the up-and-down direction. Specifically, as shown in FIG. 5 , vertical movement unit 433 is fixed to bottom 402 of platform 401. Working shaft 433A of vertical movement unit 433 is fixed to base 431. Guide poles 434R, 434L are rod-shaped members that extend downward from the bottom surface of base 431. Guide poles 434R, 434L are inserted into tubular portions 405R, 405L, respectively, provided on bottom 402 of platform 401, so as to be vertically movable. When vertical movement unit 433 is driven, base 431 moves in the up-and-down direction. The up-and-down movement of base 431 is guided by guide poles 434R, 434L and tubular portions 405R, 405L. As the base 431 moves up and down, the closed chamber bottom 440 supported by the base 431 moves up and down.

[0059] As shown in FIG. 5, a temperature adjustment mask 412R is provided at the center of the cylindrical electromagnetic wave passing portion 410R. Similarly, a temperature adjustment mask 412L is provided at the center of the electromagnetic wave passing portion 410L. The temperature adjustment masks 412R and 412L block the path of the electromagnetic waves irradiated onto the center of the circular dye adhered to the substrate S, among the paths of the electromagnetic waves irradiated onto the substrate S from the electromagnetic wave generation sources 421R and 421L of the electromagnetic wave generating portion 420. As an example, the temperature adjustment masks 412R and 412L of this embodiment include a shaft portion extending downward along the axis of the cylindrical electromagnetic wave passing portion 410R and 410L, and a disk portion extending outward in a circular shape from the bottom of the shaft portion, centered on the axis. The electromagnetic waves irradiated onto the center of the circular dye are blocked by the disk portion.

[0060] If the temperature control masks 412R and 412L were not provided, the intensity of the electromagnetic waves irradiated to the center of the circularly attached dye would be greater than the intensity of the electromagnetic waves irradiated to the peripheral areas of the dye. Furthermore, heat from the center of the circular dye is less likely to dissipate than heat from the peripheral areas. Therefore, the electromagnetic waves irradiated to the center of the circular dye are blocked by the temperature control masks 412R and 412L, preventing the temperature of the center of the dye from rising excessively compared to the temperature of the peripheral areas. As a result, the dye is more easily transferred uniformly to the lens L.

[0061] As shown in FIG. 5, the closed chamber setting unit 430 sets the staining tray 80, on which the lens L and the substrate S are placed facing each other without contacting each other, inside the closed chamber C as a unit of staining. When the staining tray 80 is set inside the closed chamber C by the closed chamber setting unit 430, the sources 421R and 421L of the electromagnetic wave generating unit 420, the substrate S, and the lens L are arranged, from top to bottom, along the vertical axis of the cylindrical electromagnetic wave passing units 410R and 410L. The electromagnetic wave generating unit 420 irradiates electromagnetic waves from above the substrate S downward. As a result, the sublimable dye attached to the lower surface of the substrate S sublimes and descends, and is transferred (deposited) onto the surface of the lens L.

[0062] Air pressure control unit 450 (see FIG. 4) includes a pump and a solenoid valve. When the pump is driven, gas inside closed chamber C is discharged to the outside through the supply and exhaust pipe. As a result, the inside of closed chamber C becomes a substantially vacuum state. When the solenoid valve is closed, the inside of closed chamber C remains airtight. When solenoid valve 33 is opened, gas is introduced from the outside into closed chamber C, which is in a reduced-pressure state, and the air pressure inside closed chamber C increases.

[0063] The mask M and the mask setting unit 460 will be described in detail with reference to Figures 7 to 9. Figure 7 is a plan view of the mask M. The upper part of Figure 7 is the rear of the mask M, and the lower part of Figure 7 is the front of the mask M.

[0064] The mask M is formed in a sheet shape (plate shape in this embodiment) from a heat-resistant material. The mask M is used in the transfer process (partial transfer process) when partial dyeing is performed. As described above, the partial dyeing in this embodiment is gradation dyeing. Gradation dyeing is a dyeing method in which the density of the dye continuously decreases from the dyed region (the region to be dyed) to the region to be dyed on the lens surface of the lens L. When partial dyeing is performed, no dye is attached (printed) to the portion of the substrate S (see FIG. 9) that faces the non-dyed region of the lens L. The dye is attached (printed) to the portion of the substrate S that faces the dyed region so that the density changes continuously.

[0065] The mask M of this embodiment includes two mask portions 91R and 91L. Approximately semicircular openings 92R and 92L are formed in each of the two mask portions 91R and 91L. Portions of each mask portion 91R and 91L other than the openings 92R and 92L block at least one of electromagnetic waves and dye. As a result, the dye in the regions of the substrate S facing the openings 92R and 92L is transferred to the lens L, but the dye in the regions facing the portions other than the openings 92R and 92L is not transferred.

[0066] Two held portions 93R, 93L are provided on the upper surface of the mask M. The held portions 93R, 93L protrude above the upper surface of the mask M. As will be described in detail later, the mask setting section 460 of this embodiment holds the mask M by holding the two held portions 93R, 93L.

[0067] 8 is a plan view of the transfer device 40 with the closed chamber bottom 440 moved to the mask attachment / detachment position. The upper part of FIG. 8 is the rear of the transfer device 40, and the lower part of FIG. 8 is the front of the transfer device 40. As shown in FIG. 8, the mask setting unit 460 of this embodiment sets a mask M on a transport unit U (staining tray 80) placed on the closed chamber bottom 440 of the closed chamber setting unit 430. Therefore, a mask M is set appropriately for each transport unit U, which is a unit of staining. The mask setting unit 460 is fixed to the rear surface of the base 404 (see FIG. 4) of the platform 401.

[0068] Specifically, the mask setting unit 460 of this embodiment can set the mask M simply by placing the mask M from above on the substrate S placed on the staining tray 80. Therefore, the mask M is easily set. The staining tray 80 with the mask M placed thereon is then set inside the closed chamber C (see FIG. 5 ) by the closed chamber setting unit 430. As a result, the mask M is positioned between the electromagnetic wave generating unit 420 and the substrate S in the space extending from the electromagnetic wave generating unit 420 to the lens L. Therefore, unlike when the mask M is positioned between the substrate S and the lens L, the dye sublimated from the substrate S is less likely to adhere to the mask M. Furthermore, the distance between the substrate S and the lens L does not change regardless of whether the mask M is set. Therefore, the transfer process is performed appropriately with the mask M set.

[0069] The mask M set in the closed chamber C (more specifically, the portions of the mask portions 91R, 91L other than the openings 92R, 92L) shields the portion of the substrate S that is projected onto the non-dyed region of the lens L (that is, the region of the substrate S that faces the non-dyed region of the lens L) when viewed from the electromagnetic wave generating unit 420. Therefore, the portion that is projected onto the non-dyed region is not heated, and therefore the transfer of dye to the non-dyed region of the lens L is appropriately suppressed.

[0070] In the mask M of this embodiment, two mask portions 91R, 91L are connected (fixed). Therefore, as shown in Fig. 8, simply by placing the mask M on the staining tray 80, not only the relative position of the mask M with respect to each lens L but also the angle (orientation) of each mask portion 91R, 91L with respect to each lens L is automatically determined. Therefore, the transfer process using the mask M can be performed more appropriately.

[0071] As shown in Fig. 7, the mask M of this embodiment has a plurality of notches 95 formed therein that correspond to the positions and shapes of the protrusions (positioning portions) 84 (see Fig. 8) of the staining tray 80. As shown in Fig. 8, the mask setting unit 460 sets the mask M in alignment with the protrusions 84 of the staining tray 80 (i.e., so that the mask M is positioned inside the plurality of protrusions 84) when the staining tray 80 is moved to the attachment / detachment position. As a result, in the staining tray 80, the mask M as well as the substrate S are appropriately positioned. In other words, in the staining tray 80, the relative positions of the mask M, substrate S, and lens L are fixed in appropriate positions by the protrusions 84.

[0072] As shown in FIG. 9 , the mask setting unit 460 of this embodiment includes a lifting / lowering unit 461, a base 462, and a pair of holders 463R and 463L. The holders 463R and 463L are fixed to the base 462. The lifting / lowering unit 461 raises and lowers the base 462 and the holders 463R and 463L. The pair of holders 463R and 463L are actuators (solenoids in this embodiment) that switch between holding and releasing the held portions 93R and 93L of the mask M. When the staining tray 80 is moved to the attachment / detachment position, the mask setting unit 460 can hold the mask M by lowering the holders 463R and 463L and sandwiching the held portions 93R and 93L of the mask M between the holders 463R and 463L. Furthermore, the mask setting section 460 can set the mask M on the staining tray 80 by releasing the holding of the mask M by the holding sections 463R, 463L when the staining tray 80 is moved to the attachment / detachment position.

[0073] (transcriptional control processing) The transfer control process executed by the transfer device 40 of this embodiment will be described with reference to Fig. 10. In the transfer control process, an appropriate transfer step is automatically executed depending on whether partial dyeing is to be performed on the lens L. The controller of the transfer device 40 (in this embodiment, the controller 71 of the control device 70) executes the transfer control process shown in Fig. 10 in accordance with a transfer control program stored in the storage device.

[0074] First, the controller 71 determines whether the transport unit U on which the lens L and the substrate S are placed has been transported by the transport device 10 to the front of the transfer device 40 (i.e., the delivery section 11 shown in FIG. 3) (S1). If the transport unit U has not been transported (S1: NO), the controller 71 enters a standby state. When the transport unit U has been transported to the front of the transfer device 40 (S1: YES), the controller 71 causes the closed chamber setting section 430 to move the closed chamber bottom 440 forward, toward the transport device 10, and receives the transport unit U from the delivery section 11 of the transport device 10 onto the transport unit placement section 441 of the closed chamber bottom 440 (S2).

[0075] Next, the controller 71 acquires information about the lens L of the transport unit U, which is read by the reading unit 2 (see FIG. 1) (S2). As described above, in this embodiment, the information about the lens L read by the reading unit 2 includes information indicating whether the lens L is a lens L for which partial dyeing is to be performed.

[0076] If the lens L of the transport unit U is not a lens L for which partial dyeing is to be performed (S5: NO), the process proceeds directly to S9. If the lens L of the transport unit U is a lens L for which partial dyeing is to be performed (S5: YES), the controller 71 causes the closed chamber set unit 430 to move the closed chamber bottom 440 to a position for attaching or detaching the mask M (S6). That is, the controller 71 moves the closed chamber bottom 440 from the transport device 10 side (front side) rearward, passes the closed chamber C, and stops it at a position for attaching or detaching behind the closed chamber C.

[0077] Next, the controller 71 sets the mask M on the staining tray 80 of the transport unit U that has been moved to the attachment / detachment position (S7). In detail, the controller 71 releases the mask M from the mask setting unit 460, thereby placing the mask M on the substrate S in the staining tray 80.

[0078] Controller 71 sets transport unit U, which is placed on closed chamber bottom 440, inside closed chamber C using closed chamber setting unit 430 (S9). In particular, controller 71 moves closed chamber bottom 440 below closed chamber C, and then raises closed chamber bottom 440, thereby setting transport unit U in a sealed state inside closed chamber C. As described above, if mask M is set on transport unit U, setting transport unit U in closed chamber C will result in the portion of base S facing the non-dyed region of lens L being shielded by mask M when viewed from the electromagnetic wave generator 420 side. Note that sources 421R, 421L of electromagnetic wave generator 420 may be provided outside closed chamber C.

[0079] The controller 71 reduces the air pressure in the closed chamber C using the air pressure control unit 450 to create a substantially vacuum state (S10). Next, the controller 71 generates electromagnetic waves from the electromagnetic wave generation unit 420 to heat the dye on the substrate S, thereby sublimating the dye and transferring it to the lens L (S11). As described above, when the mask M is set on the transport unit U, the possibility of unintentional transfer of the dye from the substrate S to the non-dyed region of the lens L is reduced. Thereafter, the controller 71 increases the air pressure in the closed chamber C using the air pressure control unit 450 to return it to atmospheric pressure (S12).

[0080] The controller 71 determines whether the mask M to be removed is included in the transport unit U (S14). If the mask M to be removed is not included (S14: NO), the process proceeds directly to S17. If the mask M to be removed is included in the transport unit U (S14: YES), the controller 71 moves the closed chamber bottom 440 to the attachment / detachment position for the mask M by the closed chamber attachment unit 430, as in the process of S6 (S15). The controller 71 removes the mask M from the staining tray 80 of the transport unit U that has been moved to the attachment / detachment position (S16). In detail, the controller 71 lowers the holding units 463R, 463L of the mask attachment unit 460 to hold the held portions 93R, 93L of the mask M, thereby removing the mask M from the staining tray 80.

[0081] Next, the controller 71 causes the closed chamber setting section 430 to move the closed chamber bottom section 440 forward, toward the transport device 10, and hands over the transport unit U to the delivery section 11 of the transport device 10 (S17). Thereafter, the process returns to S1. Through the above process, an appropriate transfer step is automatically performed depending on whether partial staining is to be performed.

[0082] The flow of multiple steps performed by the dyeing system 1 will be explained again. The steps performed by the dyeing system 1 of this embodiment include a mask setting step (S6, S7), a transfer step (S9 to S11), a mask removal step (S15, S16), a transport step, and a dye fixing step. In the mask setting step, the dyeing system 1 (transfer device 40) sets a mask M using the mask setting unit 460 when performing partial dyeing. In the transfer step, the dyeing system 1 (transfer device 40) heats the dye on the substrate S to fix the dye to the lens L while the mask M shields the non-dyed area from the electromagnetic wave generation unit 420 and the air pressure in the closed chamber C is reduced. In the mask removal step, the dyeing system 1 (transfer device 40) removes the mask M used in the transfer step. In the transport step, the dyeing system (transfer device 40) transports the lens L (in this embodiment, the dyeing tray 80 on which the lens L is placed) from the transfer device 40 to the dye fixing device 50. In the dye fixing step, the dyeing system (dye fixing device 50) heats the lens L to which the dye has been attached, causing the dye to diffuse into the lens L, thereby fixing the dye to the lens L.

[0083] The transfer device 40 of this embodiment can also execute an operation of replacing the mask M used by the mask setting unit 460. Specifically, when an instruction to replace the mask M is input, the controller 71 executes a mask removing step and a mask mounting step. In the mask removing step, the controller 71 causes the mask setting unit 460 to set the mask M on the staining tray 80, and then transfers the staining tray 80 on which the mask M has been set to the conveying device 10 as is. In the mask mounting step, the controller 71 causes the mask setting unit 460 to hold the mask M from the staining tray 80 that has been transported via the transporting device 10 with a new mask M placed on it. As a result, the mask M is properly replaced.

[0084] The techniques disclosed in the above embodiments are merely examples. Therefore, it is possible to modify the techniques exemplified in the above embodiments. For example, in the above embodiments, the mask M is set between the substrate S and the lens L. However, the mask setting unit 460 may set the mask M between the substrate S and the lens L in the space from the electromagnetic wave generating unit 420 to the lens L. In this case, the mask M blocks the sublimated dye as it moves from the substrate S to the non-dyed region of the lens L. This appropriately prevents the dye from being transferred to the non-dyed region.

[0085] Furthermore, all of the multiple steps executed in the transfer control process (see FIG. 10) of the above embodiment are automatically executed by the transfer device 40. However, the transfer method may be executed by having at least some of the multiple steps executed by an operator. For example, the mask setting step (S7) may be executed by an operator. Also, the step (S9) of setting the lens L inside the closed chamber C may be executed by an operator. All of the steps may be executed by an operator. [Explanation of symbols]
