[0008] An overview of an eyeglasses lens processing device according to an embodiment of the present disclosure will be described. Note that items classified in <> below may be used independently or in conjunction with each other.

[0009] The eyeglasses lens processing device according to the present embodiment may be a device used in a step of processing an eyeglasses lens to be framed in an eyeglasses frame. For example, the eyeglasses lens processing device may be a shaft alignment device configured to set an attachment position (in other words, a shaft alignment position) of a holding portion that sandwiches and holds the eyeglasses lens to process a peripheral edge of the eyeglasses lens with respect to the eyeglasses lens. For example, the eyeglasses lens processing device may be a cup attachment device configured to attach a cup, which is a processing tool, to an eyeglasses lens. For example, the eyeglasses lens processing device may be an eyeglasses frame shape measurement device configured to trace the contour of a rim of an eyeglasses frame and measures a shape of the rim. For example, the eyeglasses lens processing device may be an eyeglasses lens peripheral edge processing device having a processing tool for processing the peripheral edge of the eyeglasses lens. For example, the eyeglasses lens processing device may be a composite device having a plurality of functions such as a shaft alignment device, a cup attachment device, an eyeglasses frame shape measurement device, and an eyeglasses lens peripheral edge processing device.

[0010] The eyeglasses lens processing device according to the present embodiment may include a housing (for example, a housing 3). For example, the housing may cover various members used in a case where the step of processing the eyeglasses lens to be framed in the eyeglasses frame is performed. For example, the housing may be an appearance cover that forms the outside of the eyeglasses lens processing device and an appearance cover that accommodates various members. For example, the housing may accommodate, as the various members, at least one of a holding portion that holds the eyeglasses frame, a holding portion that holds the eyeglasses lens (or a support portion that supports the eyeglasses lens), an optical system that measures the eyeglasses frame or the eyeglasses lens, a processing tool that processes the peripheral edge of the eyeglasses lens, and the like.

[0011] For example, the housing may accommodate various members constituting an attachment position setting unit configured to set the attachment position of the holding portion with respect to the eyeglasses lens. For example, the attachment position setting unit may have a lens chuck shaft that sandwiches a front surface and a rear surface of the eyeglasses lens as a holding portion configured to sandwich and hold the eyeglasses lens. For example, the attachment position setting unit may include a detection optical system configured to detect an attachment position (for example, an optical center position, a geometric center position, or the like) of the holding portion with respect to the eyeglasses lens. For example, the housing may accommodate at least one of the lens chuck shaft and the detection optical system.

[0012] For example, the housing may accommodate various members constituting a cup attachment unit for attaching a cup to an eyeglasses lens. For example, the cup attachment unit may include a support portion (for example, a support pin or the like) on which the eyeglasses lens is placed to support the eyeglasses lens. For example, the cup attachment unit may include a detection optical system that detects an attachment position (for example, an optical center position, a geometric center position, or the like) at which the cup is attached to a surface of the eyeglasses lens. For example, the housing may accommodate at least one of the support portion and the detection optical system.

[0013] For example, the housing may accommodate various members constituting an eyeglasses frame shape measurement unit that measures a shape of a rim of the eyeglasses frame. For example, the cup attachment unit may include a support portion (for example, a clamp pin or the like) on which the eyeglasses frame is placed to support the eyeglasses frame. For example, the eyeglasses frame shape measurement unit may include a tracing stylus inserted into a groove of the rim of the eyeglasses frame. In this case, the shape of the rim may be measured by bringing the tracing stylus into contact with the groove of the rim by pressing the tracing stylus against the groove and moving the tracing stylus along the groove of the rim. For example, the eyeglasses frame shape measurement unit may include a measurement optical system that irradiates measurement light beam toward the groove of the rim of the eyeglasses frame and receives a reflected light beam from the groove of the rim. In this case, the shape of the rim may be measured by obtaining a cross-sectional shape based on the reflected light beam from the groove of the rim. For example, the eyeglasses frame shape measurement unit may include both the tracing stylus and the measurement optical system. For example, the housing may accommodate at least one of the support portion, the tracing stylus, and the measurement optical system.

[0014] For example, the housing may accommodate various members constituting a peripheral edge processing unit that processes the peripheral edge of the eyeglasses lens. For example, the peripheral edge processing unit may include a holding portion (for example, a lens chuck shaft) that sandwiches and holds the eyeglasses lens. For example, the peripheral edge processing unit may include a processing tool (for example, a grindstone, a cutter, an end mill, or the like) that processes the peripheral edge of the eyeglasses lens in a state where the eyeglasses lens is held by the lens chuck shaft. For example, the housing may accommodate at least one of the lens chuck shaft and the processing tool.

[0015] For example, when the housing is a composite device constituting a plurality of units such as an attachment position setting unit, a cup attachment unit, an eyeglasses frame shape measurement unit, and a peripheral edge processing unit, the housing may accommodate at least one of them.<Placement Unit>

[0016] The eyeglasses lens processing device according to the present embodiment may include a placement unit (for example, a placement unit 40). For example, the placement unit may be provided exclusively for placing a tray configured to store at least one of the eyeglasses frame and the eyeglasses lens, and may be provided outside the housing by being coupled to the housing. For example, since the eyeglasses lens processing device includes the placement unit, a space for placing the tray is secured even when a processing chamber or the like is narrow. In addition, an operator of the eyeglasses lens processing device can easily grasp the tray during work by placing the tray on the placement unit. Therefore, a possibility that the operator mistakenly inserts the eyeglasses frame or the eyeglasses lens is reduced, and work efficiency is improved.

[0017] For example, the placement unit may be coupled to the housing by being integrally formed with the housing of the eyeglasses lens processing device, and may be provided outside the housing. For example, the placement unit may be an attachment that is attachable to and detachable from the housing of the eyeglasses lens processing device, may be coupled to the housing by being mounted on the housing, and may be provided outside the housing. For example, since the work environment (as an example, the number of devices, the presence or absence of a work space, and the like) in the processing chamber is different depending on an eyeglasses shop or the like, it is easy to construct an appropriate environment according to a situation by the placement unit being the attachment.

[0018] In a case where the placement unit is provided as the attachment, the eyeglasses lens processing device may include a mounting portion for mounting the attachment. That is, the attachment may be coupled to the housing of the eyeglasses lens processing device via the mounting portion.

[0019] For example, the mounting portion included in the eyeglasses lens processing device may be configured to fix the attachment to the housing. For example, the mounting portion may include a coupling mechanism configured to couple the housing and the attachment. In this case, the coupling mechanism may be a fitting mechanism, and the mounting portion may have one of a convex portion and a concave portion, and the attachment may have the other structure. The coupling mechanism may be a magnetic mechanism, and the mounting portion and the attachment may include a ferromagnetic body and attract each other by magnetic force. The mounting portion may include, as the coupling mechanism, a mechanism obtained by combining the fitting mechanism and the magnetic mechanism, or may include a mechanism different from the fitting mechanism and the magnetic mechanism.

[0020] For example, the placement unit may be arranged at any position outside the housing of the eyeglasses lens processing device. For example, a housing surface (front surface) side facing an operator who operates the eyeglasses lens processing device is a front side of the housing. A housing surface (right side surface) side located to the right when viewed from the operator is defined as a right side of the housing. A housing surface (left side surface) side located to the left when viewed from the operator is defined as a left side of the housing. A housing surface (upper surface) side located upward when viewed from the operator is defined as an upper side of the housing. A housing surface (rear surface) side facing the housing front surface is defined as a rear side of the housing. In these cases, the placement unit may be arranged at any position of the front side, the right side, the left side, the upper side, and the rear side of the housing.

[0021] For example, the placement unit may be arranged in front of the housing of the eyeglasses lens processing device. In this case, the placement unit may be arranged to be in contact with the front surface of the housing or may be arranged to be separated from the front surface of the housing.

[0022] For example, the placement unit may be arranged on a side of the housing of the eyeglasses lens processing device. In this case, the placement unit may be arranged to be in contact with the side surface of the housing or may be arranged to be separated from the side surface of the housing. For example, the placement unit may be arranged to be in contact with the right side surface of the housing, or may be arranged to be separated from the right side surface of the housing. For example, the placement unit may be arranged to be in contact with the left side surface of the housing or may be arranged to be separated from the left side surface of the housing. The placement unit may be arranged on the side of and above the housing (as an example, on the upper right or upper left of the housing).

[0023] For example, the placement unit may be arranged above the housing of the eyeglasses lens processing device. In this case, the placement unit may be arranged to be in contact with the upper surface of the housing or may be arranged to be separated from the upper surface of the housing. The placement unit may be arranged above and on the side of the housing (as an example, on the upper right or upper left of the housing). The placement unit may be arranged above and behind the housing. For example, when a height of a housing dimension of the eyeglasses lens processing device is small, a space above the housing is likely to be empty with respect to a space of the processing chamber in which the eyeglasses lens processing device is installed. Therefore, for example, even if it is difficult to secure a space for arranging the tray near the device by arranging the placement unit above the housing, the empty space can be effectively used.<Fall Prevention Mechanism>

[0024] In the present embodiment, the placement unit may include a fall prevention mechanism. For example, the fall prevention mechanism may be a mechanism configured to prevent the tray from falling from the placement unit. For example, the fall prevention mechanism may be a mechanism configured to restrict a movement of the tray on the placement unit by being provided in the placement unit as compared with a case where the fall prevention mechanism is not provided in the placement unit. As an example, a mechanism capable of restricting the movement of the tray in a left-right direction or a front-rear direction on the placement unit may be used. For example, the eyeglasses lens processing device may oscillate in a step of processing the eyeglasses lens, but even in such a case, it is possible to prevent a possibility that the tray is displaced from the placement unit and falls.

[0025] For example, the placement unit may include a height adjustment mechanism (for example, a height adjustment mechanism 42) as the fall prevention mechanism of the tray. For example, the height adjustment mechanism may be a mechanism configured to adjust an angle of the tray with respect to a ground contact surface of the eyeglasses lens processing device. For example, the height adjustment mechanism may be a mechanism configured to horizontally adjust the angle of the tray with respect to the ground contact surface of the eyeglasses lens processing device. The horizontal may be substantially horizontal. For example, the height adjustment mechanism may be a mechanism configured to adjust the angle of the tray to be inclined with respect to the ground contact surface of the eyeglasses lens processing device. For example, the height adjustment mechanism may include a member (for example, an adjuster or the like) that changes a distance from the placement unit to the housing. For example, the housing of the eyeglasses lens processing device has various shapes, and when the housing of the eyeglasses lens processing device has a curved shape, it may be difficult to stably attach the placement unit. However, by adjusting the placement unit by the height adjustment mechanism, the tray placed on the placement unit can be maintained at a desired angle, and it is possible to reduce a possibility that the tray falls from the placement unit.

[0026] For example, the placement unit may include a wall mechanism (for example, wall mechanisms 43) as the fall prevention mechanism of the tray. For example, the wall mechanism may be a wall mechanism configured to come into contact with a side surface of the tray. For example, the wall mechanism may come into contact with at least one side surface of the tray. For example, this restricts the movement of the tray in at least one of the left-right direction and the front-rear direction, thereby reducing the possibility that the tray falls from the placement unit.

[0027] For example, the placement unit may include an anti-slip mechanism (for example, anti-slip mechanisms 44) as the fall prevention mechanism of the tray. For example, the anti-slip mechanism may be an anti-slip mechanism configured to come into contact with at least the bottom surface of the tray. For example, the anti-slip mechanism may include a member configured to generate friction between a bottom surface of the tray and a placement surface of the tray. For example, the anti-slip mechanism may include a member having an elastic body (for example, rubber or the like), a member having an uneven shape, or the like.

[0028] For example, the fall prevention mechanism included in the placement unit may be any one of the height adjustment mechanism, the wall mechanism, the anti-slip mechanism, and the like, or may be a mechanism obtained by combining these mechanisms. For example, the fall prevention mechanism may include a mechanism different from the height adjustment mechanism, the wall mechanism, and the anti-slip mechanism.<Identifier Reader>

[0029] The eyeglasses lens processing device according to the present embodiment may include an identifier reader (for example, an identifier reader 51). For example, the identifier reader may be configured to, in a case where the tray is placed on the placement unit, read an identifier attached to the tray. For example, the identifier may be at least one of a character string, an identification hole formed according to a predetermined rule, a one-dimensional code (for example, a bar code), a two-dimensional code (for example, a QR code (registered trademark) or a color code), and the like. For example, the identifier may be at least one of an electronic tag (for example, a radio frequency identifier (RFID) tag or an IC tag) using a radio wave or a magnetic field. For example, the identifier reader may be an identifier reader (for example, an identification hole reader, a bar code reader, a QR code reader, an RFID reader, an IC tag reader, or the like) corresponding to various identifiers.

[0030] For example, the identifier reader may be configured to automatically read the identifier attached to the tray, in a case where the tray is placed on the placement unit. For example, a reading range (in other words, a scanning range) of the identifier reader may be set to include a position of the identifier when the tray is placed on the placement unit.

[0031] For example, the identifier reader may be arranged such that the position of the identifier and the reading unit that scans the identifier face each other to set a reading range including the position of the identifier of the tray. As an example, in a case where a bar code is used as the identifier and a bar code reader is used as the identifier reader, the bar code reader may be arranged such that the position of the bar code is included in the scanning range. As an example, in a case where an RFID tag is used as the identifier and an RFID reader is used as the identifier reader, the RFID reader may be installed such that the position of the RFID tag is included in the scanning range.

[0032] An electronic tag such as RFID can be scanned at a longer distance than a code such as a bar code. The electronic tag such as the RFID does not require direct scanning unlike a code such as a bar code. Therefore, for example, the entire tray may be set as the scanning range of the RFID tag. For example, with such a configuration, the position of the RFID tag and the RFID reader do not necessarily need to face each other, and information associated with the RFID tag can be acquired regardless of an orientation of the tray placed on the placement unit.

[0033] For example, the identifier reader may be provided in the housing of the eyeglasses lens processing device or may be provided in the placement unit. For example, the identifier reader may be fixed and arranged to the housing or the placement unit. In this case, it is possible to save the operator the trouble of searching for and reading the identifier attached to the tray, and to improve the work efficiency. For example, the identifier reader may be movably arranged with respect to the housing or the placement unit. In this case, even when the operator changes the type of the tray to be used, a positional relationship between the identifier attached to the tray and the identifier reader can be appropriately set.<Acquisition Unit>

[0034] The eyeglasses lens processing device according to the present embodiment may include an acquisition unit (for example, a control unit 80). For example, the acquisition unit may be configured to acquire eyeglasses lens processing data corresponding to the identifier based on the identifier read by the identifier reader. For example, the eyeglasses lens processing data may be data including information on eyes of an eyeglasses wearer (as an example, eye refractive power data, a pupillary distance, an eye point position, and the like of the eyeglasses wearer). For example, the eyeglasses lens processing data may be data including a layout such as an optical center position with respect to a target lens shape. For example, the eyeglasses lens processing data may be data including various processing conditions such as a material of the eyeglasses lens, a type of the eyeglasses frame, and a processing mode (beveling, grooving, drilling, and the like) of the eyeglasses lens.

[0035] In the technology of the present disclosure, the eyeglasses lens processing device has been described as an example, but at least a part of the technology of the present disclosure is applicable to a placement unit mounted on the eyeglasses lens processing device. For example, the placement unit may be a placement unit mounted on the eyeglasses lens processing device used in the step of processing the eyeglasses lens to be framed in the eyeglasses frame, the eyeglasses lens processing device may include the housing that covers the various members used when the step of processing the eyeglasses lens to be framed in the eyeglasses frame is performed, and the placement unit may be mounted on the housing to provide a dedicated space for placing a tray for storing any one of the eyeglasses frame and the eyeglasses lens, outside the housing.<Embodiment>

[0036] An embodiment of the eyeglasses lens processing device according to the present embodiment will be described. In the present embodiment, as an eyeglasses lens processing device, an eyeglasses lens peripheral edge processing device (hereinafter, processing device) configured to process a peripheral edge of an eyeglasses lens with a processing tool in a state where the eyeglasses lens is held by a lens chuck shaft and the eyeglasses lens is held by the lens chuck shaft will be described as an example. In the present embodiment, a left-right direction (horizontal direction) of the processing device is represented as an X direction, an upper-lower direction (vertical direction) is represented as a Y direction, and a front-rear direction is represented as a Z direction.<Device Configuration>

[0037] FIG. 1 is a view illustrating an appearance configuration of the processing device. A processing device 1 includes a housing 3, a window 4, a monitor 5, an eyeglasses frame shape measurement unit 20, a blocker unit 30, the placement unit 40, an identifier reading unit 50, a lens processing mechanism unit 10 (see FIG. 4), and the like.

[0038] The housing 3 is an appearance cover that accommodates various members such as the lens processing mechanism unit 10, the eyeglasses frame shape measurement unit 20, and the blocker unit 30. The window 4 is configured to be opened and closed, and is used for inserting and removing the eyeglasses lens into and from the lens processing mechanism unit 10. The monitor 5 is a display having a touch panel function. That is, the monitor 5 functions as an operation unit (controller). The monitor 5 may not be a touch panel type, and the monitor 5 and the operation unit may be separately provided. In this case, at least one of a mouse, a joystick, a keyboard, a mobile terminal, and the like may be used as the operation unit. A signal corresponding to an operation instruction input from the monitor 5 is output to the control unit 80 to be described later.<Eyeglasses Frame Shape Measurement Unit>

[0039] The eyeglasses frame shape measurement unit 20 includes a tracing stylus configured to be brought into contact with the rim of the eyeglasses frame, and has a contact type configuration that measures the target lens shape (in this case, an inner shape of the rim) by pressing the tracing stylus against the rim and moving the tracing stylus along the rim. For example, for the detailed configuration of the eyeglasses frame shape measurement unit 20, see JP2014-52222A.

[0040] The eyeglasses frame shape measurement unit 20 may have a non-contact configuration configured to measure the target lens shape by capturing an image of the rim of the eyeglasses frame. In this case, the eyeglasses frame shape measurement unit 20 may include a measurement optical system including a light projecting optical system configured to irradiate a measurement light beam toward the rim and a light receiving optical system configured to receive a reflected light beam obtained by reflecting the measurement light beam by the rim.<Blocker Unit>

[0041] The blocker unit 30 includes a lens support mechanism, a cup attachment mechanism, and a lens measurement mechanism. For example, the lens support mechanism is configured by a support pin on which an eyeglasses lens (as an example, an unprocessed lens or a demo lens) is placed with its front surface facing upward. For example, the cup attachment mechanism attaches (axially hits) the cup to the front surface of the eyeglasses lens in a state where the eyeglasses lens is supported by the lens support mechanism. For example, the lens measurement mechanism includes an optical system that serves as both a measurement optical system that measures optical characteristics of the eyeglasses lens and a measurement optical system that acquires information (for example, an outer shape, a marking point, a hidden mark, and the like) different from the optical characteristics of the eyeglasses lens. For the detailed configuration of the blocker unit 30, see, for example, JP2013-212573A.

[0042] In the present embodiment, the blocker unit 30 can also measure the target lens shape (in this case, the outer shape of the demo lens or the template) by capturing an image of the shape of the demo lens or a template using the optical system described above.<Placement Unit>

[0043] FIGs. 2 and 3 are views illustrating the placement unit 40. FIG. 2 is a view illustrating an appearance configuration of the placement unit 40. FIG. 3 is a top view of the processing device 1 in a state where the placement unit 40 is attached to the processing device 1. For example, the placement unit 40 is an attachment configured to be attached to and detached from the housing 3 of the processing device 1. For example, the placement unit 40 is mounted on the housing 3 of the processing device 1, and is thereby arranged in a predetermined region 60 on the housing 3 that does not interfere with various works by the operator. As an example, the placement unit 40 is arranged in a region that does not interfere with the works by the operator such as an operation of the monitor 5, an operation of the eyeglasses frame shape measurement unit 20, an operation of the blocker unit 30, and an operation of the lens processing mechanism unit 10.

[0044] For example, the predetermined region 60 on the housing 3 may be a region through which the operator's hand does not pass when the operator operates the processing device 1. In other words, the predetermined region 60 on the housing 3 may be a region excluding the window 4, the monitor 5, and various members included in each unit and mechanism unit, which are exposed on the housing 3.

[0045] In the present embodiment, the placement unit 40 is arranged on a rear side on an upper surface of the housing 3 in consideration of taking out the eyeglasses frame from the eyeglasses frame shape measurement unit 20, taking out the eyeglasses lens from the lens processing mechanism unit 10 (that is, the window 4), and the like by the operator.

[0046] For example, the placement unit 40 includes a placement space 41, a coupling portion 45, the height adjustment mechanism 42, the wall mechanisms 43, the anti-slip mechanisms 44, and the like. The placement space 41 is a placement surface on which a tray 70 (see FIG. 6) configured to store an eyeglasses frame, an eyeglasses lens, and the like is placed. For example, the placement space 41 may have a shape capable of supporting the bottom surface of the tray. For example, the placement space 41 may have an area capable of supporting the bottom surface of the tray. In the present embodiment, the placement space 41 is rectangular and has an area in contact with half or more of the bottom surface of the tray. As a result, the tray bottom surface is placed in a region surrounded by a dotted line in FIG. 2.

[0047] The coupling portion 45 is configured to couple the placement unit 40 to the housing 3. For example, the coupling portion 45 is formed integrally with the placement space 41 and is fixed to a rear surface (back surface) 6 of the housing 3 with screws or the like. For example, even in a case where a rear portion of the placement space 41 does not come into contact with the housing 3, the rear portion of the placement space 41 is supported by the coupling portion 45.

[0048] The height adjustment mechanism 42 is configured to adjust the angle of the tray with respect to the ground contact surface of the processing device 1. For example, the height adjustment mechanism 42 is attached to at least one position on the lower surface of the placement space 41. In the present embodiment, the height adjustment mechanism 42 is attached to only one location on a left front side where inclination of a curved shape in the left-right direction and the front-rear direction of the housing 3 located below the placement space 41 is large among four corners of a lower surface of the placement space 41. For example, a front portion of the placement space 41 is supported by bringing the front portion of the placement space 41 into contact with the housing 3 via the height adjustment mechanism 42.

[0049] For example, the height adjustment mechanism 42 includes an adjustment knob 42a, a leg 42b, and a coupling screw (not illustrated). For example, the adjustment knob 42a is configured to change a height of the leg 42b. For example, the adjustment knob 42a is provided at one end of the coupling screw. For example, the leg 42b is fixed to one end of the coupling screw. For example, by rotating the adjustment knob 42a, a length of the coupling screw and the leg 42b can be changed to bring the leg 42b into contact with the housing 3. For example, the height adjustment mechanism 42 may be a screw-type adjuster or the like, and an angle of the placement space 41 can be maintained horizontal or inclined by using the adjuster, so that the tray can be easily prevented from falling.

[0050] The wall mechanism 43 is formed integrally with the placement space 41. For example, the wall mechanism 43 is configured to come into contact with the side surface of the tray placed in the placement space 41. For example, the wall mechanism 43 may be provided so as to come into contact with at least one side surface of the tray. For example, the wall mechanism 43 may be a plate-shaped member extending upward with respect to the placement space 41.

[0051] In the present embodiment, the wall mechanisms 43 are provided to come into contact with a right side surface and a front surface of the tray placed in the placement space 41, when viewed from the front of the processing device 1. That is, the wall mechanisms 43 are respectively provided on a right side and a front side of the placement space 41. For example, since the operator performs a work while standing in front of the processing device 1, the operator's hand easily touches the tray when taking out the eyeglasses frame or the eyeglasses lens from the tray or when taking the eyeglasses lens into or out of the lens processing mechanism unit 10. Therefore, by providing the wall mechanism in a direction in which the operator pulls the hand, it is easy to prevent the tray from falling.

[0052] The anti-slip mechanism 44 is configured to contact at least the bottom surface of the tray placed in the placement space 41. For example, the anti-slip mechanism 44 is fixed to an upper surface of the placement space 41. For example, the anti-slip mechanism 44 is arranged on at least one location on the upper surface of the placement space 41. For example, the anti-slip mechanism 44 may be arranged on the wall mechanism 43 together with the upper surface of the placement space 41. For example, the anti-slip mechanism 44 may be a member configured to generate a frictional force between the placement space 41 and the tray. In the present embodiment, anti-slip rubbers are provided as the anti-slip mechanisms 44 at the four corners of the upper surface of the placement space 41. This makes it easier to prevent the tray from falling.

[0053] In the present embodiment, at least one mechanism of the height adjustment mechanism 42, the wall mechanism 43, and the anti-slip mechanism 44 may be provided in the placement unit 40 as the fall prevention mechanism that prevents the tray from falling.<Identifier Reading Unit>

[0054] In a case where the tray 70 is placed on the placement unit 40, the identifier reading unit 50 (see FIG. 2) detects and reads the identifier attached to the tray. For example, the identifier reading unit 50 is provided in the placement unit 40. For example, the identifier reading unit 50 is fixed and arranged to the wall mechanism 43 of the placement unit 40.

[0055] For example, the identifier reading unit 50 includes an identifier reader 51. For example, the identifier reader 51 is configured to acquire various data associated with the identifier by reading the identifier attached to the tray. For example, the identifier reader 51 incorporates an illumination light source and an imaging element (for example, a line sensor), and is configured to read the identifier by emitting an illumination light beam from the illumination light source to illuminate the identifier and receiving a reflected light beam of the illumination light beam by the imaging element. For example, the identifier reader 51 is arranged at a predetermined position of the wall mechanism 43 so that a position of the identifier of the tray placed on the placement unit 40 is included in the reading range (scanning range) by an imaging element. For example, in the present embodiment, a bar code is attached as an identifier at a predetermined position on the right side surface of the tray, and a bar code reader is arranged as the identifier reader 51 at a position of the wall mechanism 43 facing the identifier when the tray is placed in the placement space 41 (see FIG. 6).<Lens Processing Mechanism Unit>

[0056] FIG. 4 is a schematic view of the lens processing mechanism unit 10. For example, the lens processing mechanism unit 10 includes a grindstone group 100, a carriage portion 200, a lens shape measurement unit 400, a lens processing unit 500, and the like.<Grindstone Group>

[0057] The grindstone group 100 is used as a processing tool for grinding the eyeglasses lens. The grindstone group 100 includes a rough grindstone 100a for plastic, a finishing grindstone 100b for a high-curve lens, a flat mirror finishing grindstone 100c, a finishing grindstone 100d for beveling and plano-processing, a rough grindstone 100e for glass, and the like. The grindstone group 100 is attached to a grindstone rotation shaft 101. The grindstone rotation shaft 101 is rotated by a motor 102. A peripheral edge of a lens held by a lens chuck shaft 202 to be described later is processed by being pressed against the grindstone group 100 rotated by driving of the motor 102.<Carriage Portion>

[0058] The carriage portion 200 includes a carriage 201, the lens chuck shaft 202, a movement support base 203, motors (motors 210 and 220), and the like. The carriage 201 holds the lens chuck shaft (lens rotation shaft) 202. The carriage 201 includes a left arm 201L and a right arm 201R. The lens chuck shaft 202 holds the lens. The lens chuck shaft 202 includes a left chuck shaft 202L and a right chuck shaft 202R.

[0059] The left chuck shaft 202L is rotatably and coaxially held by the left arm 201L of the carriage 201. The right chuck shaft 202R is rotatably and coaxially held by the right arm 201R of the carriage 201. The motor 220 is attached to the right arm 201R, and when the motor 220 is driven, a rotation transmission mechanism such as a gear (not illustrated) rotates. The left chuck shaft 202L and right chuck shaft 202R rotate in synchronization with each other via the rotation transmission mechanism. The motor 210 is attached to the right arm 201R, and when the motor 210 is driven, the right chuck shaft 202R moves toward the left chuck shaft 202L. Thus, the lens is held by the left chuck shaft 202L and the right chuck shaft 202R.

[0060] The carriage 201 is mounted on the movement support base 203. The movement support base 203 moves the carriage 201 along the lens chuck shaft 202 and shafts (shafts 208 and 209) parallel to the grindstone rotation shaft 101. A ball screw (not illustrated) extending parallel to the shaft 208 is attached to a rear portion of the movement support base 203. The ball screw is attached to a rotation shaft of a motor 230. When the motor 230 is driven, the carriage 201 linearly moves in an X-axis direction (that is, an axial direction of the lens chuck shaft 202) together with the movement support base 203. The rotation shaft of the motor 230 is provided with an encoder (not illustrated) that detects the movement of the carriage 201 in the X-axis direction. Further, a shaft 205 extending in a Y-axis direction (that is, a direction in which an inter-axis distance between the left chuck shaft 202L and the right chuck shaft 202R, and the grindstone rotation shaft 101 varies) is fixed to the movement support base 203. A motor 240 is fixed to the movement support base 203, and driving of the motor 240 is transmitted to a ball screw 207 extending in the Y-axis direction. The carriage 201 moves in the Y-axis direction by a rotation of the ball screw 207. An encoder (not illustrated) that detects a movement of the carriage 201 in the Y-axis direction is provided on a rotation shaft of the motor 240.<Lens Shape Measurement Unit>

[0061] The lens shape measurement unit 400 may be configured to measure a target lens shape (in this case, an outer shape of the demo lens) by bringing the tracing stylus into contact with the demo lens and moving the tracing stylus along an outer periphery of the demo lens. For example, since the tracing stylus is moved rearward (in a direction in which the tracing stylus is separated from the lens chuck shaft 202) according to an outer shape of the demo lens, the outer shape of the demo lens can be measured by detecting a movement position of the tracing stylus.

[0062] The lens shape measurement unit 400 can be used as a measurement unit that measures a lens surface shape (at least one of a front surface shape and a rear surface shape) in an eyeglasses lens in addition to a measurement unit that measures an outer shape of a demo lens. For example, when the lens surface shape of the eyeglasses lens is measured, the eyeglasses lens is held by the lens chuck shaft 202, and the eyeglasses lens is rotated in a state where a tip end of the tracing stylus is in contact with a front surface or a rear surface of the eyeglasses lens. At this time, the movement of the lens chuck shaft 202 in the Y-axis direction is controlled based on the target lens shape. By detecting the position of the lens chuck shaft 202 in the X-axis direction corresponding to the target lens shape on the front surface and the rear surface of the eyeglasses lens, the lens surface shape of the eyeglasses lens (for example, an edge position corresponding to the target lens shape of the lens surface, a curve value of the lens surface, an inclination angle of an edge surface, a thickness of the edge surface, and the like) can be measured.<Lens Processing Unit>

[0063] The lens processing unit 500 is used when performing at least one of drilling, grooving, and chamfering on the eyeglasses lens. The lens processing unit 500 may include an end mill as a processing tool for drilling a hole in the eyeglasses lens, a grooving cutter as a processing tool for performing grooving on the eyeglasses lens, and a chamfering grindstone. For the detailed configuration of the lens processing unit, see, for example, JP2017-177234A.<Control Unit>

[0064] FIG. 5 is a diagram illustrating a control system of the processing device 1. The control unit 80 may include a general CPU (processor), a RAM, a ROM, and the like. For example, the CPU is configured to control driving of each unit in the processing device 1. For example, the RAM is configured to temporarily store various types of information. For example, the ROM is configured to store various programs executed by the CPU. The control unit 80 may be implemented by a plurality of control units (that is, a plurality of processors).

[0065] For example, the monitor 5, the identifier reader 51, the encoders, the motors (motors 102, 210, 220, 230, 240, and the like), a nonvolatile memory 85 (hereinafter, memory 85), and the like are electrically connected to the control unit 80. The memory 85 may be a non-transitory storage medium capable of storing storage contents even when a supply of power is cut off. For example, a hard disk drive, a flash ROM, or a USB memory can be used as the memory 85.

[0066] The memory 85 may be configured to store the outer shape of the lens measured by the blocker unit 30, the outer shape of the lens measured by the lens shape measurement unit 400, an inner shape of the frame measured by the eyeglasses frame shape measurement unit 20, and the like.<Control Operation>

[0067] A control operation of the processing device 1 having the above configuration will be described.<Placement of Tray>

[0068] FIG. 6 is a view illustrating a configuration of the tray 70 and placement of the tray 70 on the placement unit 40. For example, the operator stores and manages the eyeglasses frame selected by the eyeglasses wearer and the eyeglasses lens suitable for the eye of the eyeglasses wearer in the tray 70. For example, the operator puts the eyeglasses frame and the eyeglasses lens into a placement frame 71 of the tray 70. For example, the operator puts the eyeglasses frame into the placement frame on a back side of the tray 70, and puts the pair of left and right eyeglasses lenses into the placement frame on a front side of the tray 70. At this time, an identifier 72 is arranged on a right side surface of the tray 70.

[0069] Subsequently, for example, the operator places the tray 70 in the placement space 41 of the placement unit 40. For example, the operator places the tray 70 in the placement space 41 so as to align the corners formed by the wall mechanism 43 of the placement unit 40 with the corners of the tray 70. Accordingly, the tray 70 is caught by the wall mechanism 43, and the tray 70 is less likely to fall. Accordingly, the upper surface of the placement space 41 and a lower surface of the tray 70 come into contact with each other via the anti-slip mechanism 44, and the tray 70 is less likely to fall.

[0070] For example, the operator may operate the height adjustment mechanism 42 of the placement unit 40 to adjust the height of the placement space 41 such that the placement space 41 and the tray 70 are kept in a horizontal state to the ground contact surface of the processing device 1. For example, the operator may operate the height adjustment mechanism 42 of the placement unit 40 to adjust the height of the placement space 41 such that the placement space 41 and the tray 70 are an inclined state toward the front side with respect to the ground contact surface of the processing device 1. In this case, since the tray 70 leans against the wall mechanism 43, the tray 70 is less likely to fall.

[0071] For example, when the tray 70 is placed in the placement space 41 of the placement unit 40 by the operator, the identifier 72 attached to the tray 70 is arranged at a position facing the identifier reader 51 provided in the wall mechanism 43. For example, the control unit 80 automatically detects and reads the identifier 72 by arranging the identifier 72 in front of the identifier reader 51. For example, the control unit 80 may start reading the identifier 72 based on an operation signal transmitted when the operator presses a read button (not illustrated).

[0072] For example, the control unit 80 calls the eyeglasses lens processing data associated with the identifier 72 in advance and displays the eyeglasses lens processing data on the monitor 5. For example, the identifier 72 may store a layout such as an optical center position with respect to the target lens shape of the eyeglasses lens, and the control unit 80 may display a setting screen of layout data on the monitor 5. For example, various processing conditions such as a material of the eyeglasses lens, a type of the eyeglasses frame, and a processing mode (beveling, grooving, drilling, and the like) of the eyeglasses lens may be stored in the identifier 72, and the control unit 80 may display a setting screen of the processing conditions on the monitor 5.

[0073] For example, the operator operates the monitor 5 to change parameters from each setting screen as necessary. For example, the control unit 80 acquires processing control data for processing the peripheral edge of the eyeglasses lens in consideration of layout data and processing conditions of the eyeglasses lens. As an example, the control unit 80 calculates the processing control data for controlling the rotation of the lens chuck shaft 202, the movement of the lens chuck shaft 202, and the like based on the layout data and the processing conditions of the eyeglasses lens.<Processing of Eyeglasses Lens>

[0074] For example, the operator takes out one of the eyeglasses lenses from the tray 70, holds the eyeglasses lens by the lens chuck shafts 202 (the right chuck shaft 202R and the left chuck shaft 202L) of the lens processing mechanism unit 10, and presses a processing start switch (not illustrated). For example, the control unit 80 processes the peripheral edge of the eyeglasses lens based on an operation signal from the processing start switch. For example, the control unit 80 moves the lens chuck shaft 202 in at least one of the X-axis direction, the Y-axis direction, and the Z-axis direction based on the processing control data described above, and adjusts a relative positional relationship of the eyeglasses lens with respect to a grindstone, thereby processing the peripheral edge of the eyeglasses lens (for details, see JP2017-177234A).

[0075] In the processing device 1, since the peripheral edge of the eyeglasses lens is cut by the grindstone to oscillate, the tray 70 is likely to be gradually displaced from the placement unit 40. However, in the present embodiment, the tray is hardly displaced by the height adjustment mechanism 42, the wall mechanism 43, and the anti-slip mechanism 44, and the possibility of falling of the tray is reduced.

[0076] For example, when the peripheral edge processing of one eyeglasses lens is completed, the operator returns the eyeglasses lens to the tray 70, sandwiches the other eyeglasses lens with the lens chuck shaft 202, and similarly performs the peripheral edge processing. For example, when the peripheral edge processing for both eyeglasses lenses is completed, the operator moves the tray 70 placed on the placement unit 40 to perform the next step. For example, the operator places a tray to be worked next on the placement unit 40 using the processing device 1.

[0077] As described above, for example, the eyeglasses lens processing device according to the present embodiment includes a housing covering various members used when a step of processing an eyeglasses lens to be framed in an eyeglasses frame is performed, and a placement unit provided outside the housing by being coupled to the housing, the placement unit being a placement unit provided exclusively for placing a tray storing at least one of the eyeglasses frame and the eyeglasses lens. For example, when manufacturing eyeglasses, an operator of the eyeglasses lens processing device manages the eyeglasses by using the tray storing the eyeglasses frame, an eyeglasses lens, and the like. However, in a case where a processing chamber or the like of the eyeglasses lens is narrow, there is a possibility that a space for placing the tray cannot be secured, or there is a possibility that the tray during work and a tray on standby are mixed and works becomes difficult, and thus productivity is low and efficiency is low. In the present embodiment, since the eyeglasses lens processing device has a configuration on which the tray can be placed, at least a space for placing the tray during work is secured, and the tray during work is easily recognized. Therefore, work efficiency of the step in which the operator processes the eyeglasses lens can be improved.

[0078] For example, in the eyeglasses lens processing device according to the present embodiment, the placement unit on which the tray is placed is an attachment that is attachable to and detachable from the housing. For example, since the work environment (as an example, the number of devices, the presence or absence of a work space, and the like) in the processing chamber is different depending on an eyeglasses shop or the like, it is easy to construct an appropriate environment according to a situation by the placement unit being the attachment.

[0079] For example, in the eyeglasses lens processing device according to the present embodiment, the placement unit includes a fall prevention mechanism that prevents the tray from falling from the placement unit. For example, the eyeglasses lens processing device may oscillate in the step of processing the eyeglasses lens, but even in such a case, it is possible to prevent the possibility that the tray is displaced from the placement unit and falls.

[0080] For example, in the eyeglasses lens processing device according to the present embodiment, the placement unit includes, as the fall prevention mechanism, a height adjustment mechanism that adjusts an angle of the tray with respect to the ground contact surface of the eyeglasses lens processing device. For example, there are various housings of the eyeglasses lens processing device, and an attachment portion of the placement unit is not necessarily horizontal. As an example, when the housing of the eyeglasses lens processing device has a curved shape, it may be difficult to stably attach the placement unit. However, in the present embodiment, by adjusting the placement unit by the height adjustment mechanism, the angle of the tray placed on the placement unit can be maintained, and the possibility that the tray falls from the placement unit can be reduced.

[0081] For example, in the eyeglasses lens processing device according to the present embodiment, the placement unit includes, as the fall prevention mechanism, a wall mechanism that comes into contact with a side surface of the tray. For example, the wall mechanism is brought into contact with at least a part (for example, at least one surface) of the side surface of the tray to restrict the movement of the tray in the left-right direction or the front-rear direction, thereby reducing the possibility that the tray falls from the placement unit.

[0082] For example, in the eyeglasses lens processing device according to the present embodiment, the placement unit includes, as the fall prevention mechanism, an anti-slip mechanism that comes into contact with at least a bottom surface of the tray. For example, even when the eyeglasses lens processing device oscillates in the step of processing the eyeglasses lens, it is possible to reduce the possibility that the tray falls from the placement unit due to a frictional force of the anti-slip mechanism.

[0083] For example, in the eyeglasses lens processing device according to the present embodiment, the placement unit is arranged above the housing of the eyeglasses lens processing device. For example, in an eyeglasses shop, a processing chamber for processing eyeglasses is often narrow, and it may be difficult to secure a space for placing the tray. In particular, when there are a plurality of devices, there is less space and such a problem is likely to occur. However, for example, when the height of the housing of the eyeglasses lens processing device is low, the space above the housing may be empty with respect to the space of the processing chamber. Therefore, as in the present embodiment, by arranging the placement unit of the tray above the housing, the space of the processing chamber can be effectively used.

[0084] For example, the eyeglasses lens processing device according to the present embodiment includes an identifier reader configured to read an identifier attached to the tray when the tray is placed on the placement unit, and an acquisition unit configured to acquire eyeglasses lens processing data corresponding to the identifier based on the identifier read by the identifier reader. For example, an identifier for identifying various data (as an example, eye refractive power data, the pupillary distance, the eye point position, and the like of the eyeglasses wearer) necessary for processing the eyeglasses lens, data indicating the type of the eyeglasses frame or the eyeglasses lens stored in the tray, and the like may be attached to the tray storing the eyeglasses lens. In the present embodiment, it is possible to save the operator the trouble of searching for and reading the identifier attached to the tray, and to improve the work efficiency.<Modification>

[0085] In the processing device according to the present embodiment, the configuration in which the placement unit 40 is arranged so that at least a part thereof comes into contact with the housing 3 of the processing device 1 has been described as an example, but the present disclosure is not limited thereto. More specifically, the configuration in which the placement unit 40 is arranged such that the housing 3 of the processing device 1 and the leg 42b come into contact with each other has been described as an example, but the present disclosure is not limited thereto. For example, the placement unit 40 may be arranged above the housing 3 of the processing device 1, and the placement unit 40 may be arranged without coming into contact with the housing 3 of the processing device 1. In this case, a space may be formed between the housing 3 and the placement space 41 by providing the coupling portion 45 of the placement unit 40 long.

[0086] In the processing device according to the present embodiment, the configuration in which the identifier reading unit 50 is arranged in the wall mechanism 43 provided in the placement unit 40 has been described as an example, but the present disclosure is not limited thereto. For example, the identifier reading unit 50 may be arranged at a position where the identifier 72 attached to the tray 70 can be automatically detected and read. For example, the identifier reading unit 50 may be arranged at a position where the position of the identifier 72 attached to the tray on the placement space 41 is included in the reading range (scanning range) of the identifier reader 51. As an example, the identifier reading unit 50 may be provided on the housing 3 of the processing device 1 to read the identifier 72 of the tray 70.

[0087] In the processing device according to the present embodiment, the configuration in which the identifier reading unit 50 is fixed to the wall mechanism 43 provided in the placement unit 40 has been described as an example, but the present disclosure is not limited thereto. For example, the identifier reading unit 50 may be movably arranged by the wall mechanism 43 provided in the placement unit 40. For example, the identifier reading unit 50 may be configured to move the position as appropriate in accordance with the position of the identifier 72 attached to the tray 70 when the tray 70 is placed on the placement unit 40.

[0088] FIG. 7 is a view illustrating an example of the identifier reading unit. For example, an identifier reading unit 90 may include an identifier reader 91 and a drive mechanism 92 that moves the identifier reader 91. For example, the drive mechanism 92 may include a rail or the like that slides the identifier reader 91 along the wall mechanism 43.

[0089] For example, when the tray 70 is placed on the placement unit 40, the operator checks the position of the identifier 72 attached to the tray 70 and moves the identifier reading unit 90 by the drive mechanism 92. Accordingly, the identifier 72 of the tray 70 and the identifier reader 91 may face each other, and the identifier 72 may be read by the identifier reader 91. For example, the shape of the tray 70 that stores the eyeglasses frame, the eyeglasses lens, and the like varies depending on the manufacturer or the like, and the position of the identifier 72 attached to the tray may be different. Therefore, by providing the drive mechanism 92 in the identifier reading unit 90 and changing the identifier reader 91 in accordance with the position of the identifier 72, it is easy to construct an appropriate environment when processing the peripheral edge of the eyeglasses lens.

[0090] In the processing device according to the present embodiment, the configuration in which the placement unit 40 is an attachment attachable to and detachable from the housing 3 has been described as an example, but the present disclosure is not limited thereto. For example, the placement unit 40 may be formed integrally with the housing 3. In this case, the placement unit 40 may be integrally formed in the predetermined region 60 (see FIG. 3) on the housing 3 that does not interfere various works by the operator.

[0091] In the processing device according to the present embodiment, the configuration in which one tray 70 is placed on the placement unit 40 has been described as an example, but the present disclosure is not limited thereto. For example, a plurality of trays 70 may be placed on the placement unit 40. In this case, the plurality of trays 70 may be arranged side by side by providing a large area of the placement space 41. In this case, the tray 70 may be provided with a fitting portion or the like for overlapping the trays, and a plurality of trays may be stacked on the placement space 41. For example, when the plurality of trays are stacked on the placement unit 40, the wall mechanism 43 (see FIG. 2) may be enlarged in the vertical direction with respect to the placement unit 40 to prevent the plurality of trays from falling. For example, when the plurality of trays are stacked on the placement unit 40, the identifier reading unit 50 may be configured to read identifiers corresponding to the plurality of trays.
