Description

The present invention relates to a dyed substrate manufacturing apparatus for manufacturing a dyed substrate used in a dyeing step, and a dyeing system including a dyed substrate manufacturing apparatus.

Various techniques for dyeing resin bodies such as plastic lenses have been proposed. For example, in a dyeing method called a dyeing method, a resin body is dyed by immersing the resin body in a dyeing solution. However, it is difficult to improve the working environment by the dyeing method, and it is difficult to dye a part of the resin body (for example, a lens having a high refractive index).

Therefore, a technique has been proposed in which a dye is transferred to the surface of a resin body and the resin body to which the dye is attached is heated to dye the resin body. 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, the sublimable dye applied to the substrate is sublimated in a state where the resin body and the substrate are arranged in a non-contact manner in a vacuum, so that the dye is transferred to the resin body. Next, the laser beam is scanned against the resin body, so that the resin body is heated and the dye is fixed.

In the conventional method, when dyeing the resin body, there are many steps that the operator manually performs. For example, if the dye printed on the substrate is not properly arranged on the resin body, the dyeing quality is deteriorated. The worker manually aligned the dyed substrate with respect to the resin body, and then performed the transfer step. Therefore, a technique capable of reducing the work required by the operator and dyeing the resin body more efficiently and appropriately is desired.

A typical object of the present disclosure is to provide a dyed substrate manufacturing apparatus and a dyeing system capable of improving the efficiency and quality in dyeing a resin body.

The dyed substrate manufacturing apparatus provided by the typical embodiment in the present disclosure manufactures a dyed substrate which is a substrate to which a dye transferred to the resin body is attached, which is used in a dyeing step of dyeing a resin body. A dyed substrate manufacturing apparatus for dyeing, in which a printing apparatus for printing a dye on the substrate and the dye printed by the printing apparatus are opposed to a resin body placed on a dyeing tray. A substrate mounting device for mounting the substrate at a predetermined position of the resin body on the tray is provided.

The dyeing system provided by the typical embodiment in the present disclosure includes the dyed substrate manufacturing apparatus and the transfer apparatus for transferring the dye of the dyed substrate manufactured by the dyed substrate manufacturing apparatus to the resin body. A dye fixing device for fixing the dye adhering to the surface of the resin body to the resin body by heating the resin body to which the dye is transferred by the transfer device.

According to the dyed substrate manufacturing apparatus and the dyeing system according to the present disclosure, the efficiency and quality at the time of dyeing the resin body are appropriately improved.

<Overview>
(First aspect)
The dyed substrate manufacturing apparatus exemplified in the present disclosure manufactures a dyed substrate. The dyed substrate is used in the dyeing step of dyeing the resin body. The dye transferred to the resin body adheres to the dyed substrate. The dyed substrate manufacturing apparatus includes a printing apparatus and a substrate mounting apparatus. The printing apparatus prints a dye (for example, ink containing a dye) on a substrate. The substrate mounting device places the substrate (base with dye) at a predetermined position on the resin body in the dyeing tray with the dye printed by the printing device facing the resin body placed on the dyeing tray. Place.

According to the dyed substrate manufacturing apparatus exemplified in the present disclosure, the dyed substrate is manufactured by printing the dye on the substrate by the printing apparatus. The manufactured dyed substrate is automatically placed in a predetermined position on the dyeing tray by the substrate mounting device. That is, the dyed substrate is automatically placed in an appropriate position on the dyeing tray without the operator manually placing the dyed substrate on the dyeing tray. Therefore, the efficiency and quality of dyeing the resin body are appropriately improved.

The substrate mounting device may be incorporated into the dyeing system separately from the printing device. In this case, the substrate mounting device can also be expressed as follows. A substrate mounting device that mounts the substrate at a predetermined position on the resin body in the dyeing tray with the dye printed on the substrate by the printing device facing the resin body mounted on the dyeing tray. ..

The substrate mounting device may include a substrate holding portion that holds the substrate in contact with the back surface of the printed surface on which the dye is printed among the pair of surfaces of the substrate. In this case, the substrate is appropriately held in a state in which bending, bending, breakage, etc. of the substrate are suppressed as compared with the case where one end of the substrate is held.

The substrate mounting device may include a vent. The ventilation portion is formed at a position of the substrate holding portion in contact with the back surface of the substrate. The vent allows gas to pass through. The control unit of the substrate mounting device may suck the gas from the ventilation unit by an air flow control device such as a pump or a fan to adsorb and hold the substrate on the substrate holding unit. Further, the control unit may place the substrate held by the substrate holding unit at a predetermined position on the dyeing tray by releasing the suction of gas from the ventilation unit by the airflow control device. In this case, the substrate mounting device can hold the substrate in the substrate holding portion with a stronger holding force by utilizing the suction of gas.

The substrate may be a member containing a metal layer (for example, aluminum foil or the like) and having flexibility. In this case, the thickness of the substrate may be 1 μm to 1000 μm. A substrate containing a metal layer is more likely to bend than a substrate such as paper. However, since the substrate is held by the substrate holding portion, even a substrate that is prone to bending or the like is appropriately held.

The control unit of the substrate mounting device may place the substrate held by the substrate holding unit at a predetermined position on the dyeing tray by discharging gas from the ventilation unit by the air flow control device. In this case, for example, even if the substrate is difficult to separate from the substrate holding portion due to the influence of static electricity generated between the substrate holding portion and the substrate, the gas discharged from the ventilation portion makes the substrate suitable from the substrate holding portion. Leave to. Therefore, the substrate is more appropriately placed on the dyeing tray.

The substrate mounting device may include a sensor for detecting whether or not the substrate has been detached from the substrate holding portion. When the control unit places the substrate on the dyeing tray, when the sensor detects that the substrate has not come off from the substrate holding unit, the control unit discharges the substrate from the ventilation unit to discharge the substrate from the dyeing tray. It may be placed in. In this case, the substrate is appropriately placed on the dyeing tray according to the state of the substrate.

However, when the substrate is easily separated from the surface of the substrate holding portion, the substrate mounting device does not discharge the gas from the venting portion, but simply releases the suction of the gas from the venting portion to stain the substrate on the tray for dyeing. It may be placed in. In this case, the airflow control device does not have to have the function of discharging the gas.

Further, the holding of the substrate and the release of the holding may be performed by a method different from the method using suction of gas. For example, the substrate holding device may hold the substrate by sandwiching a part of the sheet-shaped substrate in the thickness direction.

The contact surface of the substrate holding portion that contacts the back surface of the substrate may be a flat surface. In this case, since the substrate is held in contact with the flat contact surface of the substrate holding portion, the possibility of bending and bending of the substrate is further reduced. Therefore, deterioration of dyeing quality and defects in the dyeing process are less likely to occur.

The ventilation portion may include a groove portion formed on the contact surface of the substrate holding portion. The shape of the groove portion is formed in a shape corresponding to the printing shape of the dye printed on the printing surface of the substrate by the printing apparatus (preferably, the outer peripheral region substantially matches the outer peripheral region of the printing shape of the dye). May be good. In this case, the groove is located on the back surface of the dye printing area on the substrate, so that the dye printing area is more firmly held by the substrate holding portion. Therefore, it is possible to prevent bending, bending, and the like from occurring in the printed area of the dye, so that the dyeing quality is less likely to deteriorate.

The resin body to be dyed may be a substantially disk-shaped spectacle lens. The printing apparatus may print the dye (for example, ink containing the dye) in a circle on the printing surface of the substrate. The ventilation portion may include an annular groove portion formed on the contact surface of the substrate holding portion. In this case, since the annular groove portion is located on the back surface of the dye printed in a circle with respect to the substrate, the circular portion printed with the dye is more firmly held by the substrate holding portion. Therefore, the substrate is more appropriately held in the substrate holding portion in a state in which bending, bending, and the like are suppressed in the portion on which the dye is printed.

It is desirable that the annular groove portion is formed at a position of the contact surface of the substrate holding portion in contact with the back surface of the circular dye printed on the substrate. Further, a plurality of annular groove portions may be formed concentrically. In this case, the back surface of the portion of the substrate on which the dye is printed is more firmly held by the substrate holding portion.

The substrate holding portion may further include a mounting positioning portion that fits into a tray fitting portion formed at a predetermined position on the dyeing tray. In the substrate mounting device, the substrate may be placed in a predetermined position on the dyeing tray with the mounting positioning portion fitted to the tray fitting portion of the dyeing tray. In this case, by fitting the tray fitting portion and the mounting positioning portion, the relative position of the substrate holding portion with respect to the dyeing tray is fixed at a fixed position. Therefore, the substrate mounting device can more accurately mount the substrate in a predetermined position on the dyeing tray.

The substrate mounting device may further include an upside-down portion that inverts the substrate holding portion upside down by rotating the substrate holding portion. The control unit of the substrate mounting device holds the substrate on the upper part of the substrate holding portion, then inverts the substrate holding portion upside down by the upside down portion, and places the substrate in a predetermined position on the dyeing tray. May be good. Generally, the printing apparatus prints the dye on the upper surface of the substrate. On the other hand, when the dyed substrate is placed on the dyeing tray, the dye of the dyed substrate is positioned below the substrate so that the dyed substrate is placed on the resin body placed on the dyeing tray. The dyes need to face each other. In the substrate mounting device, the dye printed on the upper surface of the substrate can be easily opposed to the resin body by inverting the substrate holding portion upside down by the upside down portion. Therefore, the dyed substrate is appropriately placed on the dyeing tray.

The configuration of the upside-down portion can also be appropriately selected. For example, the upside-down portion may be upside down by rotating the substrate holding portion around a horizontally arranged rotation axis. In this case, the upside-down inverted portion has both a function of upside down the substrate holding portion and a function of moving the position of the substrate holding portion to the opposite side of the rotation axis. Therefore, the process can be easily simplified.

The substrate mounting device may further include a heating unit that heats the substrate holding portion to dry the dye (in the present disclosure, the ink containing the dye) printed on the substrate held by the substrate holding portion. .. In this case, the substrate mounting device has a function of placing the dyed substrate on the dyeing tray and also having a function of drying the dye printed on the substrate. Therefore, the dyeing process is performed more efficiently and appropriately.

When the substrate holding portion is heated to dry the dye on the substrate, the venting portion may include the above-mentioned annular groove portion. In this case, since the annular groove portion is located on the back surface of the dye printed in a circle with respect to the substrate, the circular portion printed with the dye comes into contact with the substrate holding portion more firmly. As a result, heat is easily conducted from the substrate holding portion to the dye, so that the dye is dried more appropriately.

The dyeing system of the present disclosure can also be expressed as follows. A dyed substrate manufacturing apparatus for producing a dyed substrate, which is a substrate to which a dye transferred to the resin body is attached, which is used in a dyeing step for dyeing a resin body, and the dyed substrate manufacturing apparatus manufactured by the dyed substrate manufacturing apparatus. By heating a transfer device that transfers the dye of the dye-attached substrate to the resin body and the resin body to which the dye is transferred by the transfer device, the dye adhering to the surface of the resin body is transferred to the resin body. The dye-attached substrate manufacturing apparatus includes a dye fixing device for fixing the dye on the substrate, a printing device for printing the dye on the substrate, and a resin body on which the dye printed by the printing device is placed on a dyeing tray. A dyeing system comprising: a substrate mounting device for mounting the substrate at a predetermined position of the resin body in the dyeing tray in a state of facing the dyeing tray.
In the present disclosure, as a transfer method in which the transfer device transfers the dye to the resin body, the sublimable dye printed on the substrate is sublimated in a state where the resin body and the dyed substrate face each other in a vacuum. The vapor phase transfer method of transferring the dye to the resin body is illustrated. However, it is also possible to change the transfer method. For example, the dye may be transferred to the resin body in a state where the dyed substrate is in contact with the resin body. This also applies to the second and third aspects shown below.

(Second aspect)
The dyed substrate manufacturing apparatus exemplified in the present disclosure manufactures a dyed substrate. The dyed substrate is used in the dyeing step of dyeing the resin body. The dye transferred to the resin body adheres to the dyed substrate. The dyed substrate manufacturing apparatus exemplified in the present disclosure includes a printing apparatus, a cartridge mounting portion, and an ink stirring portion. The printing device prints ink containing a dye on the substrate. The cartridge mounting unit mounts a cartridge containing ink supplied to the printing apparatus. The ink stirring unit agitates the ink in the cartridge with the cartridge mounted on the cartridge mounting portion.

According to the dyed substrate manufacturing apparatus exemplified in the present disclosure, the ink in the cartridge is automatically agitated by the ink agitating unit and supplied to the printing apparatus without the need for the operator to manually agitate the ink. Therefore, the resin body is efficiently and appropriately dyed regardless of the property that the density of the dye in the ink tends to be non-uniform.

The specific mode of the cartridge can be appropriately selected. For example, the cartridge may include a bag-shaped member (aluminum pouch or the like) filled with ink. In this case, it becomes difficult for the ink to dry in the cartridge. Further, the inside of the flexible cartridge may be directly filled with ink.

The ink stirring unit (control unit of the substrate manufacturing apparatus with dye) may stir the ink in the cartridge when the time after the last stirring of the ink has elapsed for a predetermined time or more. In this case, since the ink in the cartridge is periodically agitated, the resin body is efficiently and appropriately dyed. For example, the ink stirring unit may periodically stir the ink every time the elapsed time after the last stirring of the ink reaches a predetermined time. Further, the ink stirring unit may stir the ink when the time after the previous stirring of the ink has elapsed for a predetermined time or more and the printing start instruction to the printing device is input.

The ink stirring unit (control unit of the dyed substrate manufacturing apparatus) may agitate the ink in the cartridge while printing by the printing apparatus is not performed. In this case, during printing, the ink that has already been agitated is supplied to the inkjet head, so that the dyeing quality is improved. In addition, problems such as ink clogging are less likely to occur.

The ink stirring unit (control unit) may stir the ink in the cartridge after the power is turned on to the printing device and before printing is performed by the printing device. That is, the ink stirring unit may stir the ink when the power is turned on to the printing device. In this case, the ink in which the substance has settled while the power supply to the printing device is shut off is automatically agitated by the ink stirring unit, and then printing by the printing device is executed. Therefore, the resin body is efficiently and appropriately dyed.

It is also possible to change the timing at which the ink stirring unit stirs the ink in the cartridge. For example, the ink stirring unit may stir the ink every time the printing device prints the ink a predetermined number of times.

The ink stirring unit may stir the ink in the cartridge by tilting the cartridge mounted on the cartridge mounting portion from the used state at the time of printing and then returning the cartridge to the used state. In this case, the ink in the cartridge can be appropriately agitated without inserting any member inside the cartridge.

However, it is also possible to change the method in which the ink stirring unit stirs the ink in the cartridge. For example, the ink stirring unit may stir the ink in the cartridge by inserting a screw or the like for stirring the ink into the cartridge and driving the ink stirring unit.

The cartridge mounting portion may be capable of mounting a plurality of cartridges. The ink stirring unit may simultaneously stir the ink of a plurality of cartridges mounted on the cartridge mounting unit. In this case, the ink is agitated more efficiently than in the case where the inks of the plurality of cartridges are agitated individually.

The method for stirring the inks of a plurality of cartridges at the same time can be appropriately selected. For example, the ink stirring unit may simultaneously agitate the inks of the plurality of cartridges by inclining the entire cartridge mounting unit on which the plurality of cartridges are mounted. Further, the ink stirring unit may simultaneously stir the ink of the plurality of cartridges by collectively driving the plurality of screws inserted in each of the plurality of cartridges by one actuator (for example, a motor or the like).

The dyed substrate manufacturing apparatus may further include a weight sensor that detects the weight of the cartridge mounted on the cartridge mounting portion. The control unit of the dyed substrate manufacturing apparatus may generate ink remaining amount information regarding the remaining amount of ink in the cartridge based on the weight of the cartridge detected by the weight sensor.

As a general method for estimating the remaining amount of ink in the cartridge, a method for estimating the remaining amount of ink based on the number of times the ink is ejected from the inkjet head is known. However, the error between the remaining amount of ink estimated based on the number of times the ink is ejected and the actual remaining amount of ink tends to be large. Therefore, when estimating the remaining amount of ink based on the number of times the ink is ejected, it is estimated in order to prevent printing from being performed in a state where the ink is completely used up and causing a problem in the inkjet head. It is necessary to recommend the operator to replace the cartridge when there is enough ink remaining. In this case, the amount of ink remaining in the cartridge and discarded increases. In particular, since ink containing a dye for dyeing a resin body is expensive, it is very important to reduce the amount of ink discarded.

On the other hand, when the ink remaining amount information is generated based on the actually detected weight of the cartridge, the information is generated with higher accuracy than the case where the remaining amount is estimated by using the number of times of ink ejection. Ink. Therefore, the amount of waste ink is appropriately reduced.

The specific method of using the ink remaining amount information generated based on the weight of the cartridge can be appropriately selected. For example, the control unit may output the generated ink remaining amount information by a method such as display on the display unit or output of voice. The control unit may notify the operator of the information on the remaining amount of ink estimated based on the weight of the cartridge by a method such as display on the display unit. In addition, the control unit recommends the operator to replace the cartridge based on the information on the remaining amount of ink estimated based on the weight of the cartridge, and stops printing by the printing device until the cartridge is replaced. At least one of the actions to be performed may be executed.

The weight sensor may only detect the weight of the cartridge. Further, the weight sensor may detect the total weight of the cartridge and a member fixed to the cartridge (for example, an insertion portion into which the cartridge is inserted). Even in this case, if the weight of the member fixed to the cartridge is known, the ink remaining amount information is appropriately generated based on the weight detected by the weight sensor.

The control unit may control the ink stirring operation in the cartridge by the ink stirring unit based on the weight of the cartridge detected by the weight sensor. The weight of the cartridge detected by the weight sensor varies depending on the weight of the ink remaining in the cartridge. Therefore, by controlling the ink stirring operation by the ink stirring unit based on the detection result by the weight sensor, an appropriate stirring operation is performed according to the weight of the ink remaining in the cartridge.

A specific method for controlling the operation of the ink stirring unit based on the weight of the cartridge detected by the weight sensor can be appropriately selected. For example, the control unit may change the time interval for stirring the ink by the ink stirring unit based on the weight of the cartridge detected by the weight sensor. Further, the control unit may change the number of times the ink is agitated by the ink agitation unit based on the weight of the cartridge detected by the weight sensor.

The control unit adjusts the zero point of the weight sensor (that is, the detection result when the weight applied to the weight sensor is zero) with the cartridge tilted by 90 degrees or more from the used state by the ink stirring unit (origin). The process of adjusting to) may be performed. When the cartridge is tilted by 90 degrees or more from the used state by the ink stirring unit, the weight applied to the weight sensor from the cartridge becomes zero. By adjusting the zero point of the weight sensor in this state, the accuracy of detecting the weight of the cartridge by the weight sensor is appropriately improved. That is, the configuration in which the cartridge is tilted to stir the ink is also used for adjusting the zero point of the weight sensor, so that the accuracy of detecting the weight of the cartridge can be efficiently improved.

When the zero point of the weight sensor is adjusted, the angle at which the ink stirring unit tilts the cartridge from the used state may be larger than 90 degrees. In this case, the possibility that the weight of the cartridge is added to the weight sensor when the zero point adjustment of the weight sensor is performed is more appropriately reduced.

The cartridge mounting portion may be provided with a linear motion guide that limits the movable direction of the cartridge in the vertical direction in the used state. The weight sensor may detect the weight of the cartridge in a state where the movable direction is restricted by the linear motion guide. In this case, the accuracy of detecting the cartridge weight by the weight sensor is improved. Therefore, the accuracy of the ink remaining amount information generated based on the detection result by the weight sensor is further improved.

It is also possible to change the method of adjusting the zero point of the weight sensor. For example, the dyed substrate manufacturing apparatus may include an urging means (for example, a spring or the like) capable of urging the cartridge mounted on the cartridge mounting portion upward. The control unit may adjust the zero point of the weight sensor while the cartridge is urged upward by the urging means.

The dyeing system of the present disclosure can also be expressed as follows. A dyed substrate manufacturing apparatus for producing a dyed substrate, which is a substrate to which a dye transferred to the resin body is attached, which is used in a dyeing step for dyeing a resin body, and the dyed substrate manufacturing apparatus manufactured by the dyed substrate manufacturing apparatus. By heating a transfer device that transfers the dye of the dye-attached substrate to the resin body and the resin body to which the dye is transferred by the transfer device, the dye adhering to the surface of the resin body is transferred to the resin body. The dye-attached substrate manufacturing apparatus includes a dye fixing device for fixing to the substrate, a printing device for printing an ink containing a dye on the substrate, and a cartridge mounting for mounting a cartridge with the ink supplied to the printing device. A dyeing system comprising a unit and an ink stirring unit that stirs the ink in the cartridge with the cartridge mounted in the cartridge mounting unit.

(Third aspect)
The dyed substrate manufacturing apparatus exemplified in the present disclosure manufactures a dyed substrate. The dyed substrate is used in the dyeing step of dyeing the resin body. The dye transferred to the resin body adheres to the dyed substrate. The dyed substrate manufacturing apparatus exemplified in the present disclosure includes a printing apparatus, a conveying apparatus, and a substrate moving apparatus. The printing apparatus prints a dye for dyeing the resin body (for example, ink containing a dye) on the substrate. The transport device transports the dyeing tray on which the resin body is placed. The substrate moving device moves the substrate on which the dye is printed by the printing device from the printing position by the printing device to the transport device side.

According to the dyed substrate manufacturing apparatus exemplified in the present disclosure, the substrate on which the dye is printed by the printing apparatus is automatically moved from the printing position to the transporting apparatus side by the substrate moving apparatus. Therefore, it is not necessary for the operator to manually move the substrate from the printing position. Therefore, the resin body is dyed more efficiently and appropriately.

The dyed substrate manufacturing apparatus may further include a substrate mounting device for mounting the substrate at a predetermined position on the dyeing tray installed in the transport device. The substrate moving device may deliver the substrate on which the dye is printed by the printing device from the printing position by the printing device to the substrate mounting device. In this case, the dyed substrate on which the dye is printed by the printing apparatus is automatically conveyed in order by the substrate moving device, the substrate placing device, and the conveying device. Therefore, the burden of work performed by the worker is further reduced.

The substrate mounting device and the substrate moving device may be an integrated device. That is, one device may have both a function of moving the substrate from the printing position to the transport device side and a function of placing the moved substrate on the dyeing tray in the transport device.

The printing device may include a carriage that moves the head that ejects the dye with respect to the substrate in the main scanning direction. The substrate moving device may also serve as a sub-scanning device that moves the substrate in a sub-scanning direction that intersects the main scanning direction during printing of the dye by the printing device. In this case, both the sub-scanning during printing and the movement of the substrate from the printing position to the transport device side are appropriately performed while the configuration of the device is suppressed from becoming complicated. Further, it is easy to reduce the space for installing the device as compared with the case where the sub-scanning device is provided separately from the substrate moving device.

The printing device may include an operation unit that is operated by an operator to input an operation instruction and faces the front side of the device. The operation unit may be arranged so that the operator can operate it from the front side of the printing device. An operation instruction for performing maintenance of the printing apparatus may be input to the operation unit facing the front side. The operation unit facing the front side may be an operation panel (for example, an operation panel having a plurality of buttons, a touch panel, etc.) capable of inputting a plurality of types of operation instructions. The transport device may be installed on the side opposite to the front side (that is, the back side) of the printing device. In this case, the substrate moving device moves the dye-printed substrate to the back side of the printing device. The operator needs to perform maintenance of the printing device from the front side facing the operation unit. Therefore, by arranging the transport device on the back side of the printing device, the operator can easily perform maintenance on the printing device from the front side of the printing device. That is, the transport device or the like does not interfere with the worker during maintenance of the printing device by the worker. Further, since it is not necessary to form a space for the operator to perform maintenance in the vicinity of the transport device, it is easy to reduce the space for installing the device. Since it is not necessary to detour the transport route of the transport device in order to secure the space for performing maintenance, it is possible to suppress the lengthening of the transport route.

It should be noted that the above-mentioned operation unit may face the front side so as to be operated from the front side by the operator. Therefore, the position where the operation unit is provided may be arranged on the front surface of the housing of the printing apparatus, and the operation unit faces the front side on a surface different from the front surface (for example, the upper surface of the housing). May be arranged.

The substrate moving device may include a substrate support and a suction hole. The substrate support portion has a support surface on which the substrate is placed. The suction holes are formed on the support surface of the substrate support portion. The substrate may be adsorbed on the support surface of the substrate support portion by sucking the gas from the suction holes. In this case, the substrate moving device can appropriately support the substrate on the substrate support portion by suppressing the occurrence of damage and deformation of the substrate by utilizing the suction of gas.

The substrate moving device may further include a moving driving unit (for example, a slider or the like) that moves the substrate supporting portion in at least one one-dimensional direction. In this case, the substrate moving device can appropriately move the substrate by moving the substrate supporting portion that supports the substrate by the movement driving unit. That is, unlike the case where the substrate is moved by a pinch roller or the like, the substrate is appropriately moved in a state where bending and bending of the substrate are suppressed.

However, it is also possible to change the configuration of the substrate moving device. For example, the substrate moving device may move the substrate from the printing position to the transporting device side by at least one of a pinch roller, a robot arm, and the like.

A plurality of suction holes may be provided at least along the outer peripheral portion of the support surface of the substrate support portion. In this case, the substrate is easily adsorbed on the entire support surface of the substrate support portion. Therefore, the possibility of damage and deformation of the substrate is further reduced.

The substrate may include a metal layer (eg, aluminum foil, etc.). The substrate may be flexible. The thickness of the substrate may be 1 μm to 1000 μm. When a substrate containing a metal layer is moved by a pinch roller, the stress of the force applied to the substrate by the pinch roller may cause the substrate to bend. On the other hand, by moving the substrate support portion in a state where the substrate is adsorbed on the support surface of the substrate support portion, bending of the substrate is appropriately suppressed. The substrate may be formed by laminating a dye holding layer (for example, a layer of a hydrophilic polymer film) that enhances the holding power of the printed dye on a metal layer. In this case, the dye printed on the substrate is likely to be properly retained.

The dyeing system of the present disclosure can also be expressed as follows. A dyed substrate manufacturing apparatus for producing a dyed substrate, which is a substrate to which a dye transferred to the resin body is attached, which is used in a dyeing step for dyeing a resin body, and the dyed substrate manufacturing apparatus manufactured by the dyed substrate manufacturing apparatus. By heating a transfer device that transfers the dye of the dye-attached substrate to the resin body and the resin body to which the dye is transferred by the transfer device, the dye adhering to the surface of the resin body is transferred to the resin body. The dye-attached substrate manufacturing apparatus includes a dye fixing device for fixing to the substrate, a printing device for printing a dye on the substrate, a transport device for transporting a dyeing tray on which the resin body is placed, and the printing device. A dyeing system comprising: a substrate moving device for moving the substrate on which the dye is printed from the printing position by the printing device to the transport device side.

<Embodiment>
Hereinafter, one of the typical embodiments according to the present disclosure will be described with reference to the drawings. The dyeing system 1 automatically and continuously dyes the resin body. In the present embodiment, the resin body to be dyed is a plastic lens L (see FIG. 2 and the like) used for eyeglasses. However, at least a part of the techniques exemplified in the present disclosure can be applied to the case of dyeing a resin body other than the lens L. For example, when dyeing various resin bodies such as goggles, mobile phone covers, light covers, accessories, toys, films (for example, thickness of 400 μm or less), plates (for example, thickness of 400 μm or more), etc. It is also possible to apply at least some of the techniques exemplified in the disclosure. The resin body to be dyed also includes a resin body added to a member (for example, wood or glass) different from the resin body. Further, the dyeing system 1 of the present embodiment dyes while continuously transporting a plurality of resin bodies. However, at least a part of the techniques exemplified in the present disclosure can be adopted in a dyeing system in which resin bodies are transported one set at a time and dyed.

With reference to FIG. 1, the system configuration of the dyeing system 1 of the present embodiment will be schematically described. The dyeing system 1 of the present embodiment includes a transfer device 10, a preparation unit 20, a dyed substrate manufacturing device 30, a transfer device 40, a dye fixing device 50, a coating device 60, and a control device 70.

The transport device 10 transports the dyeing tray 80 (see FIGS. 2 and 3) on which the lens L, which is a resin body, is placed, to each device in the dyeing system 1. Specifically, the transport device 10 of the present embodiment continuously transports a plurality of dyeing trays 80 in the dyeing system 1. The transport device 10 of the present embodiment is a tray for dyeing in the order of the preparation unit 20, the dyed substrate manufacturing device 30, the transfer device 40, the dye fixing device 50, and the coating device 60 (that is, from left to right in FIG. 1). Transport 80.

The preparation unit 20 prepares before actually performing the transfer and fixing of the dye to the lens L. Specifically, the preparation unit 20 of the present embodiment includes an optical characteristic measuring device 21 and a rotating device 22.

The optical characteristic measuring device 21 includes a measuring optical system for measuring the optical characteristics of the lens L. The optical characteristic measuring device 21 projects the measured light beam onto the lens L and receives the measured light beam passing through the lens L to receive the optical characteristics of the lens L (for example, spherical power, random vision power, random vision axis angle, prism power, etc.). ) Is read. By measuring the astigmatic axis angle of the lens L, the angle in the rotation direction of the lens L is determined. Since a known configuration can be adopted for the optical characteristic measuring device 21, detailed description thereof will be omitted (the configuration of the optical characteristic measuring device 21 is described in, for example, Japanese Patent Application Laid-Open No. 2012-107910).

The rotating device 22 includes a support portion that supports the lens L and an actuator (for example, a motor or the like) that rotates the lens L supported by the support portion. The rotating device 22 defines the rotation direction of the lens L by rotating the lens L. The rotating device 22 of the present embodiment defines the rotation direction of the lens L as a target direction by rotating the lens L based on the angle of the rotation direction of the lens L measured by the optical characteristic measuring device 21. .. The dyeing system 1 of the present embodiment prints on the substrate S by rotating the lens L when the gradation dyeing is executed and the lens L does not have a target shape about the geometric center axis. The angle of the lens L is adjusted with respect to the angle of the ink (dye).

The dyed substrate manufacturing apparatus 30 manufactures a dyed substrate used in the dyeing step of dyeing a resin body (lens L). The dyed substrate includes a sheet-shaped substrate S (see FIG. 4) and a dye that adheres to one surface of the substrate S. In this embodiment, the substrate S has a metal layer (in this embodiment, an aluminum foil layer) and is flexible. Specifically, the substrate S is formed by laminating a dye holding layer (in this embodiment, a layer of a hydrophilic polymer film) for enhancing the holding power of the printed dye on a metal layer. ing. Therefore, the dye printed on the substrate S is easily held properly. The thickness of the substrate S in this embodiment is 1 μm to 1000 μm. However, as the material of the substrate S, other materials such as paper, glass plate, heat-resistant resin, and ceramic can also be used.

The dyed substrate manufacturing apparatus 30 of the present embodiment includes a printing apparatus 100 (see FIG. 4). The printing apparatus 100 manufactures a dyed substrate by printing an ink containing a dye on the substrate S. In the dyeing system 1 of the present embodiment, in order to appropriately transfer the dye to the lens L while preventing the dye from agglomerating or the like, the substrate S and the lens L are separated from each other in a vacuum (including substantially vacuum) environment. By heating the dye of the substrate S in a state of facing each other, the dye is transferred (deposited) to the surface of the lens L (the dyeing method in the present embodiment is referred to as a vapor phase transfer dyeing method). Therefore, as the printing apparatus 100, an inkjet printer that prints ink containing a sublimation dye on the substrate S is used. Further, the printing apparatus 100 can also print a normal ink containing no sublimation dye on the substrate S. The printing device 100 executes 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 “PC”). As a result, an appropriate position of the substrate S is performed. An appropriate amount of ink (dye) adheres to the surface. It is also easy to prepare a dyed substrate S for performing gradation dyeing.

It is also possible to change the configuration of the printing apparatus 100. For example, the printing device may be a laser printer. In this case, the toner may contain a sublimation dye. Further, instead of the printing device 100, the dye may be attached to the substrate S by a dispenser (liquid quantitative coating device), a roller, or the like. The details of the dyed substrate manufacturing apparatus 30 will be described later.

The transfer device 40 transfers the dye from the substrate S to the lens L in a state where the dye adhering to the substrate S faces the lens L. As described above, in the present embodiment, the dye is transferred from the substrate S to the lens L by the vapor phase transfer method. However, it is also possible to change the method of transferring the dye to the lens L. For example, the dye may be transferred from the substrate S to the lens L in a state where the dye of the substrate S is in contact with the lens L.

The dye fixing device 50 heats the lens L to which the dye is transferred by the transfer device 40 to fix the dye adhering to the surface of the lens L to the resin body. The dye fixing device 50 of the present embodiment heats the lens L by irradiating the lens L with a laser beam which is an electromagnetic wave. However, a device (for example, an oven or the like) that irradiates the lens L with an electromagnetic wave other than the laser light may be used as the dye fixing device.

The coating device 60 coats the surface of the lens L on which the dye is fixed by the dye fixing device 50. A specific method for the coating device 60 to coat the lens L can be appropriately selected. For example, at least one of a spray method, an inkjet method, a spin method, a dip method, and the like may be adopted as the coating method. The type of coating may be appropriately selected from many types (for example, hard coat, antireflection coat, water repellent coat, primer coat, etc.).

The control device 70 controls various controls in the dyeing system 1. As the control device 70, various information processing devices (for example, at least one of a PC, a server, a mobile terminal, and the like) can be used. The control device 70 includes a controller (for example, a CPU or the like) 71 that controls control, and a database 72 that stores various data. It is also possible to change the configuration of the control device 70. First, a plurality of devices may cooperate to function as the control device 70. For example, the control device that controls various controls in the dyeing system 1 and the control device provided with the database 72 may be different devices. Further, the controllers of a plurality of devices may cooperate to execute various controls in the dyeing system 1. For example, at least one of a transfer device 10, an optical property measuring device 21, a rotating device 22, a dyed substrate manufacturing device 30, a transfer device 40, a dye fixing device 50, and a coating device 60 often includes a controller. In this case, the controller of the control device 70 and the controller of another device may cooperate to control the dyeing system 1.

(Tray for dyeing)
The dyeing tray 80 used in the dyeing system 1 of the present embodiment will be described with reference to FIGS. 2 and 3. FIG. 2 is a perspective view of a dyeing tray 80 in a state where two lenses L are installed (placed) and a substrate S is not installed. FIG. 3 is a perspective view of the dyeing tray 80 showing the mounting frame 89, the lens L, and the spacer 87 mounted on one of the two mounting portions 82 in an exploded manner.

As shown in FIGS. 2 and 3, the dyeing tray 80 of the present embodiment includes a tray body 81, a mounting frame 89, and a spacer 87. The tray body 81, the mounting frame 89, and the spacer 87 are all made of a material capable of withstanding high temperature and low pressure (substantially vacuum). A resin body (lens L in this embodiment) to be dyed is placed on the mounting frame 89. The mounting frame 89 of the present embodiment is formed in a ring shape having an outer diameter slightly larger than that of the lens L. The spacer 87 extends upward in a cylindrical shape (cylindrical shape) from the outer peripheral portion of the mounting frame 89 where the lens L is mounted. A mounting portion 82 is formed on the tray body 81. A mounting frame 89 and a spacer 87 are detachably mounted on the mounting portion 82. In this embodiment, two mounting portions 82 are formed on one tray main body 81. Therefore, the pair (left and right) lenses L used for one pair of eyeglasses are dyed while being placed on one dyeing tray 80.

A substrate mounting portion 85 on which a sheet-shaped substrate S (see FIG. 4) to which a sublimation dye adheres is placed is formed on the outer side of the tray main body 81 above the mounting portion 82. By mounting the substrate S on the substrate mounting portion 85, the sublimation dye adhering to the substrate S faces the lens L mounted on the mounting frame 89.

The tubular spacer 87 forms a space between the substrate S mounted on the substrate mounting portion 85 and the lens L mounted on the mounting frame 89. Therefore, the sublimation dye is appropriately transferred from the substrate S to the lens L through the space formed by the spacer 87. When the mounting frame 89 and the spacer 87 are mounted on the mounting portion 82, the upper end portion of the spacer 87 projects upward from the mounting surface of the substrate mounting portion 85. Therefore, the substrate S mounted on the substrate mounting portion 85 and the upper end portion of the spacer 87 are likely to be in close contact with each other, so that the sublimated dye is less likely to leak to the outside.

In the tray body 81, at a position outside the mounting portion 82 (specifically, outside the substrate mounting portion 85), above the mounting surface of the substrate mounting portion 85 on which the substrate S is mounted. A protrusion 84 is provided.

The shape of the substrate S of the present embodiment is a rectangular sheet that covers both of the two mounting portions 82. In the present embodiment, a plurality (8 pieces) are placed along the outer periphery of the substrate S in a state of being placed in an appropriate position of the dyeing tray 80 (that is, in a state of being properly placed on the substrate mounting portion 85). ) Is formed. Therefore, the substrate S is appropriately positioned with respect to the lens L by placing the substrate S in the region (base mounting portion 85) surrounded by the plurality of protrusions 84. Further, the possibility that the position of the placed substrate S is displaced with respect to the lens L is reduced. That is, at least a part of the plurality of protrusions 84 in the present embodiment (in this embodiment, all the protrusions 84) functions as a positioning portion for positioning the substrate S with respect to the lens L.

Further, at least a part of the plurality of protrusions 84 (in this embodiment, all the protrusions 84) in the dyeing tray 80 is a placement positioning portion formed on the substrate holding portion 410 of the substrate mounting device 400 described later. Fits into 413 (see FIG. 11). As a result, the relative position of the substrate holding portion 410 with respect to the dyeing tray 80 is fixed at a predetermined position. That is, the protrusion 84 in the present embodiment functions as a tray fitting portion that fits into the mounting positioning portion 413 of the substrate holding portion 410. The details will be described later.

Needless to say, when a plurality of protrusions 84 are provided on the tray main body 81, the number of protrusions 84 is not limited to eight. It is also possible to change the shape of the protrusion 84. For example, the protrusion may be a rib-shaped member extending upward from a position along the outer periphery of the substrate S.

(Dye-attached substrate manufacturing equipment)
The dyed substrate manufacturing apparatus 30 of the present embodiment will be described with reference to FIGS. 4 to 12. In the following description, the upper right side of the paper surface in FIG. 4 is the front side of the dyed substrate manufacturing apparatus 30, and the lower left side of the paper surface is the back side of the dyed substrate manufacturing apparatus 30. The lower right side of the paper surface in FIG. 4 is the left side of the dyed substrate manufacturing apparatus 30, and the upper left side of the paper surface is the right side of the dyed substrate manufacturing apparatus 30. 4, FIG. 8, FIG. 9, and FIG. 10 are perspective views of each device as viewed diagonally from the rear left. On the other hand, FIG. 5 is a perspective view of the device as viewed diagonally from the front left. 11 and 12 are perspective views of the device viewed diagonally forward to the right (direction of arrow F in FIG. 4).

As shown in FIG. 4, the dyed substrate manufacturing apparatus 30 of the present embodiment includes a printing apparatus 100, a substrate transfer apparatus 200, a substrate moving apparatus 300 (see FIGS. 9 and 10), and a substrate placing apparatus 400. The substrate moving device 300 is not shown in FIG. 4 because it is in a state of being moved inside the printing device 100 in FIG. The substrate moving device 300 is arranged closer to the printing device 100 than the substrate transfer device 200. Each of the printing device 100, the substrate transfer device 200, the substrate moving device 300, and the substrate placing device 400 is assembled to the housing 31. Further, the transport device 10 is also assembled in the housing 31.

The printing apparatus 100 prints ink containing a dye on the sheet-shaped substrate S. The substrate transfer device 200 transfers the substrate S from the substrate stock unit 210 that stocks the substrate S on which ink is not printed to the substrate transfer device 300 (see FIGS. 9 and 10). The substrate moving device 300 moves the substrate S (dye-attached substrate) on which ink is printed by the printing device 100 from the printing position by the printing device 100 to the transport device 10 side. Further, the substrate transfer device 200 transfers the substrate S on which the ink is printed from the substrate moving device 300 to the substrate mounting device 400. The substrate mounting device 400 is a lens L on the dyeing tray 80 with the printed dye (ink) facing the lens L (see FIGS. 2 and 3) placed on the dyeing tray 80. The substrate S is placed at a predetermined position (base mounting portion 85). The details of each part will be described below.

(Conveyor)
The transport device 10 will be described with reference to FIG. The transport device 10 includes a pair of rails 11 extending in the transport direction. A rotating belt 12 arranged along the rail 11 is provided in the vicinity of the rail 11. The rotary belt 12 is connected to a conveyor motor (for example, a step motor) 13. The rotary belt 12 rotates by driving the conveyor motor 13. As the rotating belt 12 rotates, the dyeing tray 80 moves along the rail 11 in the transport direction.

The transport device 10 includes a plurality of tray positioning units 14. The tray positioning unit 14 is provided at a predetermined position on the transport path between the pair of rails 11. When the tray positioning unit 14 is moved upward by the vertical movement actuator (not shown), the tray positioning unit 14 comes into contact with the dyeing tray 80 that has been transported along the transport path, and the transport of the dyeing tray 80 is stopped at a predetermined position. do. Therefore, the transport device 10 of the present embodiment can accurately stop the dyeing tray at a predetermined position on the transport path. Further, sensors (not shown) for detecting the presence / absence of the dyeing tray 80 are provided at a plurality of positions of the rail 11. The control device 70 can detect the position of the dyeing tray 80 conveyed by the transfer device 10 based on the detection results of each of the plurality of sensors.

The transport device 10 of the present embodiment transports the dyeing tray 80 from the upper left side to the lower right side in FIG. A transfer device 40, a dye fixing device 50, and the like (see FIG. 1) are arranged on the downstream side (lower right side in FIG. 4) of the transfer path shown in FIG. 4 of the transfer paths of the transfer device 10. The dyed substrate manufacturing apparatus 30 places the substrate (dyeed substrate) S on which the ink is printed by the printing apparatus 100 on the dyeing tray 80 by the substrate placing apparatus 400. After that, the dyeing tray 80 is transferred to the transfer device 40 by the transfer device 10. The positional relationship between the printing device 100 and the transport device 10 will be described later.

(Printing equipment)
The printing apparatus 100 will be described with reference to FIGS. 4 to 7. The printing apparatus 100 of the present embodiment is an inkjet printer capable of printing an ink containing a dye (specifically, a sublimable dye) on the substrate S. As shown in FIG. 4, the printing apparatus 100 includes an inkjet head 110, a carriage 120, an operation unit 130, and a cartridge mounting unit 140. Further, as shown in FIGS. 5 to 7, the printing apparatus 100 includes an ink stirring unit 150.

As shown in FIG. 4, the inkjet head 110 is provided inside the printing apparatus 100. The inkjet head 110 ejects ink. Specifically, the inkjet head 110 is provided with a plurality of (8 in this embodiment) ink ejection portions. Each ink ejection unit downwards ink supplied from each of a plurality of (8 in this embodiment) cartridges 141 (see FIGS. 5 to 7) mounted on the cartridge mounting unit 140 toward the substrate S. Discharge to.

The carriage 120 moves the inkjet head 110 in the main scanning direction MD with respect to the substrate S. The control unit (controller 71 in this embodiment) of the dyed substrate manufacturing apparatus 30 moves the inkjet head 110 in the main scanning direction MD by controlling the drive of the main scanning motor (not shown) included in the carriage 120. Let me. The controller 71 controls the ejection of ink from the inkjet head 110 while controlling the relative main scanning and sub-scanning of the substrate S and the inkjet head 110 to apply ink to the two-dimensional region of the substrate S. Print. The method of sub-scanning in this embodiment will be described later.

The operation unit 130 is installed facing the front side (upper right side in FIG. 4) of the printing device. In other words, the operation unit 130 is arranged so that the operator can operate it from the front side of the printing device 100. The operation unit 130 is operated by an operator during maintenance of the printing apparatus 100. That is, an operation instruction for performing maintenance is input to the operation unit 130 facing the front side. The operation unit 130 of the present embodiment is an operation panel capable of inputting a plurality of types of operation instructions, and includes, for example, at least one of a plurality of buttons and a touch panel. When the operation unit 130 is operated by an operator, various operation instructions are input to the printing device 100. Therefore, the operator operates the operation unit 130 from the front side of the printing device 100 when performing maintenance of the printing device 100 or the like. The operation unit 130 of the present embodiment is installed on the front surface of the housing of the printing apparatus 100. However, the operation unit may be installed so as to face the front on a surface different from the front of the housing (for example, the upper surface or the like).

Here, the transport device 10 for transporting the dyeing tray 80 is installed on the side opposite to the front side of the printing device 100 (that is, the back side of the printing device 100). Therefore, unlike the case where the transfer device 10 is installed on the front side of the printing device 100 (that is, the side facing the operation unit 130), when the operator operates the operation unit 130, the transfer device 10 operates. It is hard to get in the way. Therefore, the operator can easily perform maintenance of the printing device 100 from the front side of the printing device 100. Further, since it is not necessary to form a space for the operator to perform maintenance in the vicinity of the transport device 10, it is easy to reduce the space for installing the device. Since it is not necessary to detour the transport path of the transport device 10 in order to secure a space for performing maintenance, it is possible to suppress the lengthening of the transport route.

The cartridge mounting portion 140 of the present embodiment will be described in detail with reference to FIGS. 5 to 7. The cartridge mounting unit 140 mounts a cartridge 141 containing ink supplied to the inkjet head 110. The cartridge 141 of the present embodiment is configured by arranging a bag (aluminum pouch) filled with ink inside a housing having appropriate rigidity. As shown in FIG. 5, the cartridge mounting portion 140 includes a plurality of insertion portions 143 and linear motion guides 145 (8 in this embodiment). A cartridge 141 is inserted into each insertion portion 143. That is, the cartridge mounting unit 140 of the present embodiment can mount a plurality of cartridges 141. In the present embodiment, the cartridge 141 is mounted on the cartridge mounting portion 140 by inserting the cartridge 141 inside the cylindrical insertion portion 143. Further, a guide piece 144 having a guide hole through which the linear motion guide 145 is inserted is fixed to the insertion portion 143.

The linear motion guide 145 limits (guides) the movable direction of the insertion portion 143 into which the cartridge 141 is inserted in a one-dimensional direction. Specifically, the linear motion guide 145 of the present embodiment moves the insertion portion 143 in the vertical direction (vertical direction) in the usage state (state shown in FIG. 6) when the ink is printed by the printing apparatus 100. Limit to. In the present embodiment, the guide hole of the guide piece 144 fixed to the insertion portion 143 is inserted into the linear motion guide 145 extending in the vertical direction in the used state, so that the movable direction of the insertion portion 143 (cartridge 141) is vertical. Restricted in direction.

As shown in FIGS. 6 and 7, the cartridge mounting unit 140 includes a plurality of (eight in this embodiment) weight sensors 147. Each weight sensor 147 detects the weight of each of the plurality of cartridges 141 mounted on the cartridge mounting portion 140 during use. As shown in FIG. 6, each of the plurality of weight sensors 147 in the present embodiment is provided at a position in contact with the bottom portion of the insertion portion 143 during the use state. Therefore, during the use state, the total value of the weight of the insertion portion 143 and the weight of the cartridge 141 mounted on the insertion portion 143 is detected by the weight sensor 147.

In the present embodiment, the weight obtained by subtracting the weight of the insertion portion 143 and the weight of the housing of the cartridge 141 from the weight detected by the weight sensor 147 is the weight of the ink remaining inside the housing of the cartridge 141. Approximates to. Therefore, the controller 71 can generate ink remaining amount information regarding the remaining amount of ink in the cartridge 141 based on the weight detected during the use state by the weight sensor 147. For example, the dyed substrate manufacturing apparatus 30 stores the weight detected by the weight sensor 147 in the database 72 as an offset value in a state where the cartridge 141 in a state where the ink is completely empty is mounted on the insertion portion 143. You may be doing it. The controller 71 may generate ink remaining amount information based on the weight detected by the weight sensor 147 and the offset value.

As described above, the movable direction of the insertion portion 143 in the used state is limited to the vertical direction by the linear motion guide 145. As a result, the detection accuracy of the weight of the cartridge 141 (specifically, the total weight of the cartridge 141 and the insertion portion 143) by the weight sensor 147 is improved.

Further, in the present embodiment, each insertion portion 143 is provided with a needle, a tube, and a solenoid valve. When the cartridge 141 is attached to the insertion portion 143, the needle penetrates the rubber stopper of the aluminum pouch in the cartridge 141. As a result, the ink in the cartridge 141 is supplied to the inkjet head 110 via the needle and tube. In addition, the solenoid valve can control the flow of ink in the tube by switching between compression and release of the tube. For example, the controller 71 can reduce the possibility of air entering the tube by stopping the flow of ink in the tube by a solenoid valve when the cartridge 141 is replaced.

The ink stirring unit 150 of the present embodiment will be described with reference to FIGS. 5 to 7. The ink stirring unit 150 stirs the ink in the cartridge 141 with the cartridge 141 mounted on the cartridge mounting unit 140. Therefore, the ink in the cartridge 141 is automatically agitated by the ink agitating unit 150 and supplied to the inkjet head 110 without the need for the operator to manually agitate the ink. Therefore, the ink is appropriately printed on the substrate S regardless of the property that the density of the ink containing the dye is likely to be different.

The ink stirring unit 150 of the present embodiment is used from the state of use (state shown in FIG. 6) when printing the cartridge 141 mounted on the cartridge mounting unit 140 (that is, when supplying ink to the inkjet head 110). , Tilt to the tilted state (state shown in FIG. 7). After that, the ink stirring unit 150 returns the cartridge 141 from the tilted state to the used state. As a result, the ink in the cartridge 141 is appropriately agitated without inserting any member into the cartridge 141.

Specifically, the ink stirring unit 150 includes an actuator (solenoid in this embodiment) 151 and a rotation support unit 152. The rotation support portion 152 rotatably supports the cartridge mounting portion 140 provided with the plurality of insertion portions 143 around the rotation shaft 153. The operating portion of the actuator 151 (in this embodiment, the operating shaft of the solenoid) is connected to a position of the rotation support portion 152 deviated from the rotating shaft 153 (in the present embodiment, below the rotating shaft 153 in FIG. 6). ing. Therefore, when the actuator 151 is operated, the cartridge 141 mounted on the cartridge mounting portion 140 is tilted at the position where it is used for printing (see FIG. 6) and when the ink is agitated, with the rotation shaft 153 as the center. In detail, the actuator 151 pushes out the working shaft to put the cartridge 141 into the used state (see FIG. 6), and the actuator 151 pulls in the working shaft to rotate the cartridge 141. Is in an inclined state (see FIG. 7). Therefore, the ink in the cartridge 141 is appropriately agitated.

As described above, the cartridge mounting unit 140 can mount a plurality of cartridges 141. The ink stirring unit 150 can simultaneously stir the ink of the plurality of cartridges 141 by operating one actuator 151 and tilting the entire cartridge mounting unit 140 to which the plurality of cartridges 141 are mounted. Therefore, the inks of the plurality of cartridges 141 are agitated more efficiently.

The controller 71 (control unit of the dyed substrate manufacturing apparatus 30 in the present embodiment) is an ink stirring unit after the power is turned on to the printing apparatus 100 and before printing is performed by the printing apparatus 100. The ink in the cartridge 141 is agitated by 150. In other words, the controller 71 of the present embodiment agitates the ink when the power is turned on to the printing apparatus 100. Therefore, the ink in the cartridge 141 whose dye concentration is non-uniform while the power supply to the printing device 100 is cut off is automatically agitated by the ink stirring unit 150, and then printing by the printing device 100 is executed.

Further, the controller 71 causes the ink stirring unit 150 to agitate the ink in the cartridge 141 when a predetermined time or more has elapsed since the ink was agitated last time. Therefore, since the ink in the cartridge 141 is periodically agitated, the lens L is appropriately dyed. The controller 71 periodically stirs the ink every time the time after the last stirring of the ink reaches a predetermined time. However, the controller 71 may agitate the ink when a predetermined time or more has elapsed since the ink was agitated last time and a printing start instruction is input to the printing device 100.

Further, the controller 71 stirs the ink in the cartridge 141 while the printing device 100 is not printing. Therefore, during printing, the ink that has already been agitated is supplied to the inkjet head 110, so that the dyeing quality is improved. In addition, problems such as ink clogging are less likely to occur.

The controller 71 controls the ink stirring operation in the cartridge 141 by the ink stirring unit 150 based on the weight of the cartridge 141 detected by the weight sensor 147. Therefore, an appropriate stirring operation is performed according to the weight of the ink remaining in the cartridge 141. For example, the controller 71 may change the interval of time for stirring the ink by the ink stirring unit 150 based on the weight detected by the weight sensor 147. Further, the controller 71 may change the number of times the ink is stirred by the ink stirring unit 150 or the like based on the weight detected by the weight sensor 147.

As described above, the controller 71 generates ink remaining amount information regarding the remaining amount of ink in the cartridge 141 based on the weight detected by the weight sensor 147. Therefore, information on the remaining amount of ink is generated with higher accuracy than in the case of estimating the remaining amount using the number of times of ejection of ink. Specifically, in the present embodiment, the controller 71 displays information on the remaining amount of ink estimated based on the weight detected by the weight sensor 147 on a display unit (not shown), by voice, or the like. Notify the worker. Further, the controller 71 is recommended to be replaced in order to recommend the operator to replace the cartridge 141 when the remaining amount of ink estimated based on the weight detected by the weight sensor 147 is equal to or less than the first threshold value. Perform the action. Further, when the estimated remaining amount of ink becomes equal to or less than the second threshold value smaller than the first threshold value, the controller 71 executes a print stop operation of stopping printing until the cartridge 141 is replaced. The method of outputting the ink remaining amount information described in the present embodiment is merely an example. That is, of course, it is possible to change the output method of the ink remaining amount information.

As shown in FIG. 7, in the ink stirring unit 150 of the present embodiment, the rotation angle θ of the cartridge 141 in the tilted state with respect to the cartridge 141 in the used state is set to 90 degrees or more. Specifically, in the present embodiment, the rotation angle θ is set to an angle larger than 90 degrees (for example, 93 degrees to 95 degrees). Therefore, while the cartridge 141 is tilted, the weight from the cartridge 141 to the weight sensor 147 becomes zero. The controller 71 performs zero point adjustment of the weight sensor 147 while the cartridge 141 is tilted (that is, the cartridge 141 is tilted by 90 degrees or more from the used state by the ink stirring unit 150). Therefore, the accuracy of weight detection by the weight sensor 147 is appropriately improved.

In the present embodiment, the main body of the suction holding portion 220 is a plate-shaped member having a plurality of circular holes formed therein. The suction holding portion 220 includes a plurality of suction ports 221. The plurality of suction ports 221 face downward from the main body of the suction holding portion 220 and are connected to an ejector (not shown) for sucking gas. The ejector uses the Venturi effect to generate negative pressure. A pump or the like may be used instead of the ejector. The first slider 230 moves the suction holding portion 220 in the first direction (in the present embodiment, the left-right direction in the dyed substrate manufacturing apparatus 30). The second slider 240 moves the suction holding portion 220 in a direction horizontally intersecting with the first direction (in the present embodiment, the front-back direction in the dyed substrate manufacturing apparatus 30). Further, the elevating device 250 raises and lowers (moves up and down) the suction holding portion 220.

The controller 71 controls the drive of the first slider 230 and the second slider 240, and with the suction holding portion 220 positioned above the substrate stock portion 210, the suction holding portion 220 is lowered by a predetermined distance by the elevating device 250. .. As a result, the plurality of suction ports 221 in the suction holding portion 220 come into contact with the uppermost substrate S of the substrate stock portion 210. Next, the controller 71 causes the suction holding portion 220 to hold the substrate S by sucking gas from the suction port 221 by an ejector (not shown). Next, the controller 71 controls the driving of the first slider 230, the second slider 240, and the elevating device 250 to move the base S to a predetermined position of the base moving device 300 (see FIGS. 9 and 10). Specifically, the suction holding portion 220 is arranged at a position higher than the substrate supporting portion 330 of the substrate moving device 300. The controller 71 moves the suction holding portion 220 holding the substrate S above (vertically above) the substrate supporting portion 330 of the substrate moving device 300. After that, the controller 71 delivers the substrate S to the substrate support portion 330 of the substrate moving device 300 by releasing the suction of the gas from the suction port 221.

Further, the controller 71 controls the drive of the first slider 230 and the second slider 240, and the elevating device 250 is in a state where the suction holding portion 220 is positioned above the substrate support portion 330 (see FIGS. 9 and 10).

The substrate moving device 300 will be described with reference to FIGS. 9 and 10. As shown in FIG. 9, the substrate moving device 300 is a transfer device installed outside the printing device 100 from a position (printing position) where printing is performed by the inkjet head 110 (see FIG. 4) inside the printing device 100. The substrate S can be moved to the 10 (see FIG. 4) side. As described above, the transport device 10 of the present embodiment is arranged on the back side (lower left side of the paper surface in FIG. 9) of the printing device 100. Therefore, the substrate moving device 300 moves the substrate S from the printing position inside the printing device 100 to the back side of the printing device 100.

As shown in FIG. 10, the substrate moving device 300 of the present embodiment includes a base portion 310, a vibration absorber 320, a substrate support portion 330, and a slider 340. The base portion 310 is a plate-shaped member that serves as a base that supports the entire base moving device 300 including the base support portion 330. The base portion 310 is fixed to the printing apparatus 100 (see FIG. 4) via a vibration absorber (for example, seismic isolation rubber or the like) 320. The vibration absorber 320 absorbs vibration. In the present embodiment, the vibration absorbers 320 are installed at a plurality of locations so that the positions of the centers of gravity of the plurality of vibration absorbers 320 and the positions of the centers of gravity of the printing apparatus 100 coincide with each other in a plan view.

The substrate support portion 330 supports the substrate S from below. In the substrate moving device 300 of the present embodiment, the two substrate supporting portions 330 are provided side by side in the left-right direction (direction along the main scanning direction MD of the printing device 100). However, the number of the substrate support portions 330 included in the substrate moving device 300 may be one or three or more.

The substrate support portion 330 of the present embodiment includes a support surface 331, a suction hole 332, and a pump connection portion 333. The substrate S is placed on the support surface 331. The support surface 331 of the present embodiment is a flat surface arranged horizontally. Further, the support surface 331 of the present embodiment is formed in a shape slightly larger than the shape of the rectangular substrate S. Therefore, the sheet-shaped substrate S is difficult to separate from the support surface 331. The suction hole 332 is formed on the support surface 331 of the substrate support portion 330. The suction hole 332 is connected to a pump (not shown) that sucks gas via the pump connection portion 333. The controller 71 controls the drive of the pump to suck the gas from the suction hole 332, so that the base S can be sucked on the support surface 331 of the base support portion 330. Therefore, the substrate S is appropriately supported by the support surface 331 in a state where the occurrence of damage and deformation of the substrate S is suppressed.

Specifically, a plurality (8 in this embodiment) of suction holes 332 of the present embodiment are provided along at least the outer peripheral portion of the support surface 331 of the substrate support portion 330. As a result, the sheet-shaped substrate S is sucked by the suction holes 332 at a plurality of points on the outer peripheral portion. Therefore, the substrate S is more appropriately supported by the substrate support portion 330.

Further, as described above, the substrate S of the present embodiment includes a metal layer and has flexibility. When the substrate S containing a metal layer and having flexibility is moved by a pinch roller, the substrate S may be bent by the stress of the force applied from the pinch roller to the substrate S. On the other hand, in the substrate moving device 300 of the present embodiment, the substrate supporting portion 330 is moved in a state where the substrate is adsorbed on the support surface 331 of the substrate supporting portion 330, so that the bending of the moving substrate S is appropriate. Can be suppressed.

The slider 340 moves the substrate support 330 in one-dimensional direction. Specifically, the slider 340 of the present embodiment moves the substrate support portion 330 in the front-rear direction in the dyed substrate manufacturing apparatus 30 to transfer the substrate S supported by the substrate support portion 330 from the printing position to the transfer device 10. Can be moved to the side.

Further, in the present embodiment, the front-back direction in the dyed substrate manufacturing apparatus 30 coincides with the sub-scanning direction SD of the printing apparatus 100. The substrate moving device 300 of the present embodiment has a substrate S on a sub-scanning direction SD that intersects (orthogonally in this embodiment) the main scanning direction MD by the carriage 120 (see FIG. 4) while printing ink by the printing device 100. To move. That is, the substrate moving device 300 of the present embodiment also serves as a sub-scanning device that moves the substrate S in the sub-scanning direction SD during printing by the printing device 100. Therefore, the sub-scanning during printing and the movement of the substrate S from the printing position are both appropriately executed by the substrate moving device 300 in a state where the device configuration is suppressed from becoming complicated.

When the substrate moving device 300 moves the substrate S supported by the substrate supporting portion 330 to the side closest to the transfer device 10, the substrate S is adjacent to the substrate mounting device 400 (see FIGS. 11 and 12). The substrate moving device 300 moves the substrate S on which the ink is printed from the printing position to the transfer device 10 side, thereby delivering the substrate S to the substrate mounting device 400. Therefore, the substrate S on which the ink is printed by the printing device 100 is automatically conveyed in order by the substrate moving device 300, the substrate placing device 400, and the conveying device 10. Therefore, the burden on the worker is further reduced.

(Phypokeimenon mounting device)
The substrate mounting device 400 will be described with reference to FIGS. 11 and 12. As described above, in the substrate mounting device 400, the dye (ink) printed on the substrate S is opposed to the lens L (see FIGS. 2 and 3) mounted on the dyeing tray 80. The substrate S is placed at a predetermined position of the lens L on the dyeing tray 80 (in this embodiment, the substrate mounting portion 85 above the lens L). Therefore, even if the operator does not manually place the substrate S on the dyeing tray 80, the substrate S is automatically and appropriately placed at an appropriate position on the dyeing tray 80. As described above, FIGS. 11 and 12 are views viewed from diagonally forward right (direction of arrow F in FIG. 4) of the device. The substrate mounting device 400 of the present embodiment includes a substrate holding unit 410, an upside down unit 430, and a heating unit 450.

The substrate holding portion 410 holds the substrate S in a state of being in contact with the back surface of the printed surface on which the dye (ink) is printed among the pair of surfaces of the substrate S in the form of a sheet. Therefore, the bending, bending, breakage, and the like of the substrate S are less likely to occur as compared with the case where one end of the substrate S is held. In the substrate mounting device 400 of the present embodiment, the two substrate holding portions 410 are provided side by side in the left-right direction (direction along the main scanning direction MD of the printing device 100). However, the number of the substrate holding portions 410 included in the substrate mounting device 400 may be one or three or more.

Specifically, as shown in FIG. 11, a ventilation portion 411 is formed in the substrate holding portion 410 at a position of the substrate S in contact with the back surface of the printed surface. The ventilation unit 411 allows the gas to pass through the air flow control device (for example, a pump or the like, not shown) capable of switching between suction and discharge of the gas. In the present embodiment, the ventilation portion 411 formed on the surface of the substrate holding portion 410 (the contact surface in contact with the substrate S) is connected to the air flow control device through the flow path inside the substrate holding portion 410.

The contact surface of the substrate holding portion 410 that contacts the back surface of the substrate S is a flat surface. Therefore, the sheet-shaped substrate S is held in contact with the flat contact surface of the substrate holding portion 410. As a result, the possibility that the substrate S is bent, bent, or the like is further reduced.

In the present embodiment, the ventilation portion 411 includes a groove portion of the substrate holding portion 410 formed on the contact surface in contact with the substrate S. The shape of the groove portion (annular ring) corresponds to the printing shape (circular in this embodiment) of the dye printed on the printing surface of the substrate S by the printing apparatus 100. Therefore, by locating the groove portion on the back surface of the dye printing region on the substrate S, the dye printing region is more firmly held by the substrate holding portion 410.

In other words, in the present embodiment, the ventilation portion 411 includes an annular groove portion formed on the contact surface in contact with the substrate S in the substrate holding portion 410. Further, as described above, the resin body dyed by the dyeing system 1 of the present embodiment is a substantially disk-shaped lens (glass lens) L. The ink containing the dye is printed in a circle on the printing surface of the substrate S. The ventilation portion 411 including the annular groove portion is located on the back surface of the dye printed in a circle with respect to the substrate S. As a result, the circular portion on which the dye is printed is more firmly held by the substrate holding portion 410. Therefore, it is more appropriately suppressed that the portion where the dye is printed is bent or the like.

It should be noted that a plurality of circular grooves provided in the ventilation portion 411 are formed concentrically. Therefore, the substrate S is more firmly held by the substrate holding portion 410 as compared with the case where there is only one circular groove portion.

The upside-down portion 430 inverts the substrate holding portion 410 that holds the substrate S upside down. Specifically, the upside-down portion 430 of the present embodiment includes a rotating shaft 431 and an actuator (air cylinder in this embodiment) 432 and 433. The rotation shaft 431 is arranged in the horizontal direction and is fixed to the substrate holding portion 410. The actuating portion of the actuators 432 and 433 (in this embodiment, the actuating shaft of the air cylinder) is connected to a part of the substrate holding portion 410.

As shown in FIGS. 11 and 12, when the actuators 432 and 433 are operated, the substrate holding portion 410 fixed to the rotating shaft 431 rotates 180 degrees around the rotating shaft 431. As a result, the substrate holding portion 410 is turned upside down. Further, when the substrate holding portion 410 is rotated from the state shown in FIG. 11 to the state shown in FIG. 12 by the upside down portion 430, the substrate holding portion 410 moves above the dyeing tray 80 on the transport device 10. .. That is, the upside-down portion 430 has both a function of upside down the substrate S held by the substrate holding portion 410 and a function of moving the substrate S upward of the dyeing tray 80.

As shown in FIG. 11, a mounting positioning unit 413 is provided at a predetermined position of the substrate holding unit 410. The mounting positioning portion 413 of the present embodiment is a plurality of recesses. When the substrate holding portion 410 is turned upside down by the upside down portion 430, the plurality of mounting positioning portions 413 provided on the substrate holding portion 410 are attached to the plurality of protrusions (tray fitting portions) 84 in the dyeing tray 80. Fit. As a result, the relative position of the substrate holding portion 410 with respect to the dyeing tray 80 is fixed at a predetermined position. Therefore, the substrate mounting device 400 can more accurately mount the substrate S on the substrate mounting portion 85 of the dyeing tray 80.

The heating unit 450 heats the substrate holding portion 410 to dry the ink printed on the substrate S held by the substrate holding portion 410. Therefore, the substrate mounting device 400 has a function of placing the substrate S on the dyeing tray 80 and a function of drying the ink printed on the substrate S. Specifically, the heating unit 450 is formed of a substance having high thermal conductivity and is arranged at a position adjacent to the substrate holding unit 410 (in the present embodiment, a position adjacent to the position below the substrate holding unit 410). Will be done. The heating unit 450 is provided with a heater mounting unit 451 on which a heater (not shown) is mounted. The heating unit 450 is heated by driving the heater mounted on the heater mounting unit 451. As a result, the substrate holding portion 410 adjacent to the heating portion 450 is heated.

As described above, the ventilation portion 411 including the annular groove portion is located on the back surface of the dye (ink) printed in a circle with respect to the substrate S. Therefore, the circular portion of the substrate S on which the ink is printed comes into contact with the substrate holding portion 410 more firmly. Therefore, heat is easily conducted from the substrate holding portion 410 to the ink, so that the ink is dried more appropriately.

Radiant heat reflectors 453 are provided on the side surfaces and the bottom surface of the heating unit 450. A gap is provided between the radiant heat reflector 453 and the heating unit 450. Further, the surface of the radiant heat reflector 453 facing the heating unit 450 is formed in a mirror shape so as to easily reflect the radiant heat from the heating unit 450. Therefore, it is appropriately suppressed by the radiant heat reflector 453 that the radiant heat from the heating unit 450 is transmitted to the side and the lower side of the heating unit 450.

The controller 71 sucks the gas from the ventilation unit 411 by the air flow control device to hold the substrate S in the substrate holding unit 410. Further, the controller 71 is held by the substrate holding portion 410 by releasing the suction of gas from the ventilation portion 411 by the airflow control device in a state where the substrate holding portion 410 is turned upside down by the upside down portion. The substrate S is placed in a predetermined position on the dyeing tray 80. Therefore, the substrate mounting device 400 can appropriately hold and place the substrate S while suppressing the occurrence of damage to the substrate S by utilizing the suction of gas.

Further, the controller 71 discharges gas from the ventilation unit 411 by the airflow control device in a state where the substrate holding portion 410 is turned upside down by the upside down portion, so that the substrate S held by the substrate holding portion 410 is held. , Placed in a predetermined position on the dyeing tray 80. Therefore, even if the substrate S is difficult to separate from the substrate holding portion 410 due to the influence of static electricity generated between the substrate holding portion 410 and the substrate, the substrate S is kept in the substrate holding portion by the gas discharged from the ventilation portion 411. Easy to get away from 410 properly.

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, only some of the plurality of techniques exemplified in the above embodiment may be adopted.
