Description

[Technical Field]

[0001] The present disclosure relates to a deodorizing system for eyeglass lens periphery processing that deodorizes odors generated during eyeglass lens periphery processing, and a deodorizing unit for eyeglass lens periphery processing. [Background technology]

[0002] There is known an eyeglass lens processing device that includes a processing chamber in which processing tools (e.g., grindstones, cutters) for processing the periphery of an eyeglass lens are placed, and that processes the periphery of the eyeglass lens using the processing tools to fit the shape of the eyeglass frame (see, for example, Patent Document 1). When processing the periphery of an eyeglass lens (e.g., a plastic lens, etc.), a foul odor may be generated depending on the components contained in the eyeglass lens. For this reason, there is known a technology in which a deodorizing device is attached to the processing chamber of the eyeglass lens processing device or to a drainage pipe connected to the processing chamber, and a deodorizing member of the deodorizing device is used to deodorize the odor generated in the processing chamber (see, for example, Patent Document 2).

[0004] [Patent Document 2] Japanese Patent Application Publication No. 6-226629 Summary of the Invention [Problem to be solved by the invention]

[0005] Conventional deodorizing devices use replaceable deodorizing members that are highly effective at deodorizing. However, as the deodorizing performance of these members approaches its odor absorption limit, the members' deodorizing performance declines, necessitating replacement. The more eyeglass lenses processed, the more frequently the deodorizing members must be replaced. This is both a time-consuming task for workers and a costly replacement process. Furthermore, as the deodorizing performance of the deodorizing members declines, odors within the processing chamber may not be sufficiently removed, potentially resulting in the odors being released into the atmosphere outside the processing chamber.

[0006] In consideration of the above problems, the technical objective of the present disclosure is to provide a deodorizing system for eyeglass lens peripheral processing and a deodorizing unit for eyeglass lens peripheral processing that can further reduce odors while suppressing a decline in deodorizing performance. [Means for solving the problem]

(2) A deodorizing unit for eyeglass lens peripheral processing according to a second aspect of the present disclosure is a deodorizing unit that deodorizes odors generated in conjunction with peripheral processing of eyeglass lenses, and is equipped with a first deodorizing unit having a first deodorizing member that deodorizes odors and a first path that sends odors from the processing chamber of an eyeglass lens processing device to the first deodorizing member, a second deodorizing member that has a more immediate deodorizing effect than the first deodorizing member and requires replacement, and a second path that is at least partially different from the first path and sends odors from the processing chamber to the second deodorizing member, and is characterized in that the sending path that sends odors from the processing chamber is set to at least one of the first path and the second path depending on the control state of the eyeglass lens processing device, thereby deodorizing odors generated in the eyeglass lens processing device.

DETAILED DESCRIPTION OF THE INVENTION

[0009] <Summary> An overview of the deodorizing system for eyeglass lens periphery processing according to this embodiment will be described. The items classified in < > below can be used independently or in conjunction with each other.

[0010] <Deodorizing system for eyeglass lens periphery processing> The deodorizing unit (e.g., deodorizing unit 500) of the present disclosure is used in a deodorizing system for eyeglass lens periphery processing (e.g., deodorizing system 10 for eyeglass lens periphery processing). The deodorizing system for eyeglass lens periphery processing may include an eyeglass lens processing apparatus (e.g., eyeglass lens processing apparatus 100) and a deodorizing unit. The eyeglass lens processing apparatus processes the periphery of the eyeglass lens with a processing tool (e.g., processing tool unit 140 or grinding wheel 150). The deodorizing unit deodorizes odors generated during the periphery processing of the eyeglass lens. The deodorizing unit may include a first deodorizing unit (e.g., first deodorizing unit 300) and a second deodorizing unit (e.g., second deodorizing unit 400). The deodorizing system also includes setting means (e.g., blower 340, blower 440, switching valve 460, etc.).

[0011] <Eyeglass lens processing equipment> The eyeglass lens processing device includes a lens holding shaft (e.g., lens chuck shaft 120) that holds the eyeglass lens, a processing tool (e.g., processing tool unit 140 or grinding wheel 150) for processing the periphery of the eyeglass lens, and a moving unit (e.g., moving unit 135) that three-dimensionally changes the positional relationship between the processing position of the eyeglass lens held by the lens holding shaft and the processing tool. The eyeglass lens processing device also includes a processing chamber (e.g., processing chamber 180). The lens holding shaft and processing tool are arranged in the processing chamber. For example, the periphery of the eyeglass lens is processed by the processing tool by controlling the moving unit based on processing data obtained from the lens shape.

[0012] <Grinding water treatment equipment> The deodorizing system for eyeglass lens peripheral processing of the present disclosure may further include a grinding water treatment device (e.g., grinding water treatment device 200). The grinding water treatment device uses a pump to draw up grinding water stored in a tank (e.g., tank 203) and supply it to the eyeglass lens processing device, and returns grinding water discharged from the processing chamber of the eyeglass lens processing device to the tank for reuse. For example, the processing chamber is provided with a nozzle (e.g., nozzle 170) of a grinding water supply means (e.g., grinding water supply means 210).

[0013] <First deodorizing unit> The deodorizing system for eyeglass lens periphery processing of the present disclosure may include a first deodorizing unit. The first deodorizing unit may have a first deodorizing member (e.g., first deodorizing member 330) and a first path (e.g., first path 600) that sends odors from the processing chamber of the eyeglass lens processing device to the first deodorizing member. The first deodorizing member deodorizes the odors sent out from the processing chamber of the eyeglass lens processing device. The first deodorizing unit may be configured to take in the odors sent out from the first path and return the gas that has passed through the first deodorizing member to the processing chamber of the eyeglass lens processing device. The first deodorizing unit may also be configured to take in the odors sent out from the first path and send the gas that has passed through the first deodorizing member to the outside.

[0014] The first deodorizing member may be a deodorizing member that has a longer-lasting deodorizing performance and requires fewer replacement cycles than the second deodorizing member described below. The first deodorizing member may be a deodorizing member that deodorizes odors over time. The first deodorizing member deodorizes odors using a photocatalyst, an ion oxidation catalyst, or the like. As an example, the photocatalyst may be titanium oxide, zinc oxide, tungsten oxide, or a mixture thereof.

[0015] The first path sends odors from the processing chamber of the eyeglass lens processing apparatus to the first deodorizing member. The first path may be a path that draws in odors generated in the processing chamber of the eyeglass lens processing apparatus and introduces the odors into the first deodorizing unit. Furthermore, when the deodorizing system for eyeglass lens periphery processing includes a grinding water treatment device, the first path may be a path that draws in odors generated in a tank (e.g., tank 203) of the grinding water treatment device and introduces the odors into the first deodorizing unit. For example, wastewater from the processing chamber of the eyeglass lens processing apparatus flows into the tank through a drain hose (e.g., drain hose 201) of the grinding water treatment device. Therefore, the first path may include a path between the processing chamber drain hose of the eyeglass lens processing apparatus and a space within the tank (e.g., space 211). The space within the tank is the space between the top surface of the grinding water in the tank and the lid (e.g., lid 204) of the grinding water treatment device, and may be provided to prevent the grinding water from overflowing from the grinding water treatment device 200.

[0016] For example, odors generated from the processing chamber of the eyeglass lens processing device may reach the inside of the tank of the grinding water treatment device. Furthermore, odors from eyeglass lenses are also generated from processing waste, grinding water, etc., left after lens processing by the eyeglass lens processing device. Therefore, by having the first path pass through the grinding water treatment device, odors remaining in the processing chamber of the eyeglass lens processing device and the tank of the grinding water treatment device can also be deodorized.

[0017] <Second deodorizing unit> The deodorizing system for eyeglass lens periphery processing of the present disclosure may include a second deodorizing unit. The second deodorizing unit may have a second deodorizing member (e.g., second deodorizing member 430) and a second path (e.g., second path 700) that sends odors from the processing chamber of the eyeglass lens processing device to the second deodorizing member. The second deodorizing member deodorizes odors sent out from the processing chamber of the eyeglass lens processing device. The second path sends odors from the processing chamber of the eyeglass lens processing device to the second deodorizing member.

[0018] The second deodorizing member may be a deodorizing member that has a faster effect than the first deodorizing member and that requires replacement. The second deodorizing member deodorizes odors using activated carbon, an ozone decomposition catalyst, or the like.

[0019] The second path sends odors from the processing chamber of the eyeglass lens processing apparatus to the second deodorizing member. The second path may be a path that draws in odors generated in the processing chamber of the eyeglass lens processing apparatus and introduces the odors into the second deodorizing unit. Furthermore, when the deodorizing system for eyeglass lens periphery processing includes a grinding water treatment device, the second path may be a path that draws in odors generated in a tank (e.g., tank 203) of the grinding water treatment device and introduces the odors into the second deodorizing unit. For example, when the deodorizing system for eyeglass lens periphery processing includes a grinding water treatment device, wastewater from the processing chamber of the eyeglass lens processing apparatus flows into the tank through a drain hose (e.g., drain hose 201) of the grinding water treatment device. Therefore, the second path may include a path through the drain hose and a space within the tank (e.g., space 209). Therefore, the second path may include a path through the drain hose and a space within the tank. Furthermore, the second path may be composed of a path that sends out odor via the first path and the first deodorizing member, and may be a path that takes in the odor discharged through the first deodorizing member and causes the odor to flow into the second deodorizing member.

[0020] Conventional deodorizing devices use replaceable deodorizing members that are highly effective at deodorizing. However, as these deodorizing members approach their odor absorption limit, their deodorizing performance declines, necessitating replacement. Therefore, by switching the deodorizing member in use to deodorize odors depending on the control state (processing state) of the eyeglass lens processing device, the number of times the deodorizing member is used (wear and tear) that requires replacement can be reduced while preventing a decline in deodorizing performance. This reduces the replacement frequency of deodorizing members that require replacement, thereby reducing the effort required by workers to replace them and reducing the costs associated with replacing them. Furthermore, it reduces the amount of deodorizing members that are discarded, which is environmentally friendly.

[0021] <Setting method> The deodorizing system for eyeglass lens periphery processing of the present disclosure may include a setting means. The setting means sets the delivery path for delivering odor from the processing chamber to at least one of the first path and the second path depending on the control state of the eyeglass lens processing device. The setting means may have a first intake means (blower 340) arranged in the first deodorizing unit, a second intake means (blower 440) arranged in the second deodorizing unit, and a control unit, and the control unit controls the driving of the first intake means and the second intake means to set the delivery path to at least one of the first path and the second path. The setting means may also have a switching valve (e.g., switching valve 460) that switches between opening and closing (in other words, connecting and disconnecting) the first path and the second path, and a control unit, and the control unit controls the switching valve to set the delivery path to at least one of the first path and the second path. The setting means may also include a control unit (e.g., control unit 60). The setting means may be controlled in accordance with the control state of the eyeglass lens processing apparatus by the control unit.

[0022] The setting means may be configured to set the delivery path to the first path in a first state in which the eyeglass lens processing device is waiting for the processing tool to process the periphery of the eyeglass lens. The first state may be any state in which the eyeglass lens processing device is waiting for the processing tool to process the periphery of the eyeglass lens. That is, for example, the first state may be any state in which the processing tool is not controlling the processing of the periphery of the eyeglass lens. Also, for example, the first state may be a state that does not correspond to the second state described below. As an example, the first state may be a state in which the processing tool is not processing the periphery of the eyeglass lens. As another example, the first state may be a state in which the processing tool is controlling the movement of the processing tool in order to process the eyeglass lens. As another example, the first state may be a state in which grinding water is not supplied to the eyeglass lens processing device from the grinding water treatment device.

[0023] The setting means may be configured to set the delivery path to the second path in a second state during control of edge processing of the eyeglass lens by the processing tool. The second state during edge processing control may be a control period from the start of processing of the eyeglass lens by the processing tool to the end of processing (for example, a period during which the eyeglass lens processing device performs various lens processing such as rough processing, finishing processing, and chamfering). The second state during edge processing control may also be a period during which grinding water is supplied from the grinding water treatment device. Furthermore, grinding water may be used to cool the processed portion of the eyeglass lens during processing of the eyeglass lens by the processing tool, and may be supplied for a predetermined period during processing with the processing tool or after processing with the processing tool is completed. For example, grinding water may be used to suppress scattering of processing chips generated during processing with the processing tool, and may be supplied during the period during which the processing tool is in contact with the eyeglass lens during processing.

[0024] For example, in the second state, a large amount of bad odor is generated due to components contained in the eyeglass lenses during lens processing. On the other hand, in the first state, bad odors are generated from processing waste, grinding water, etc. after processing is completed, but the generation of bad odors is less than in the second state. Therefore, for example, by setting the odor discharge path according to the control state (processing state) of the eyeglass lens processing device (in other words, by using different deodorizing members depending on the generation status of bad odors), it is possible to reduce the use of the second deodorizing member that requires replacement (i.e., odor absorption). Therefore, the deodorizing function of the second deodorizing member can be extended.

[0025] In the second state, the setting means may set the delivery path to a second path configured to deliver the odor via the first path and the first deodorizing member. In this case, in a state where a large amount of bad odor is generated due to components contained in eyeglass lenses, as in the second state, the first deodorizing member and the second deodorizing member are used together to deodorize the odor, thereby reducing odor adsorption to the second deodorizing member. This further reduces the use of the second deodorizing member, which requires replacement (i.e., odor adsorption).

[0026] In the second state, in which the processing tool controls the peripheral processing of the eyeglass lens, the setting means may set the delivery path to both the first path and the second path. This allows the first deodorizing member to first reduce a certain amount of odor, thereby reducing odor adsorption to the second deodorizing member. Furthermore, in the second state, in which a large amount of bad odor is generated due to components contained in the eyeglass lens, the first deodorizing member and the second deodorizing member can be used together to deodorize the odor, thereby reducing odor adsorption to the second deodorizing member. This further reduces the use of the second deodorizing member, which requires replacement (i.e., odor adsorption).

[0027] <Other> The deodorizing unit may have a third path (e.g., exhaust pipe 350). The third path may be a path for returning the gas that has passed through at least the first deodorizing member back to the processing chamber of the eyeglass lens processing device. The third path may have a sending path set to the first path, so that odors that have not been deodorized by the first deodorizing member are returned to the first deodorizing member again and circulated between the processing chamber and the first deodorizing member.

[0028] The first deodorizing member has a lower deodorizing effect and is not as fast acting as the second deodorizing member, but the provision of the third path allows the odor-containing gas in the processing chamber to pass through the first deodorizing member multiple times, thereby effectively deodorizing the odor in the processing chamber. This third path is particularly advantageous when set in the first state described above.

[0029] <Example> An example of the deodorizing system for eyeglass lens periphery processing according to this embodiment will be described.

[0030] <Appearance of the device> FIG. 1 is an external view of a deodorizing system 10 for eyeglass lens periphery processing. The deodorizing system 10 of this embodiment includes an eyeglass lens processing apparatus 100, a grinding water treatment device 200, a deodorizing unit 500, and the like. The eyeglass lens processing apparatus 100 processes the periphery of an eyeglass lens using a processing tool. The grinding water treatment device 200 separates processing debris and water contained in wastewater discharged from the eyeglass lens processing apparatus 100, and pumps the filtered water into the eyeglass lens processing apparatus 100. The deodorizing unit 500 deodorizes odors generated during the periphery processing of eyeglass lenses. The deodorizing unit 500 includes a first deodorizing unit 300, a second deodorizing unit 400, and the like.

[0031] The first deodorizing unit 300 has a first deodorizing member 330 that deodorizes odors, and a first path 600 that sends odors from the processing chamber 180 of the eyeglass lens processing apparatus 100 to the first deodorizing member 330 (details will be described later). The second deodorizing unit 400 has a second deodorizing member 430 that has a more immediate deodorizing effect than the first deodorizing member and needs to be replaced, and a second path 700 that sends odors from the processing chamber 180 to the second deodorizing member 430 (details will be described later).

[0032] The eyeglass lens processing apparatus 100, grinding water treatment apparatus 200, and deodorizing unit 500 (first deodorizing unit 300, second deodorizing unit 400) are connected in an airtight manner. Also, by adopting such a connection configuration, a tightly sealed structure is provided at each connection point between the processing chamber 180 and the drain hose 201 of the grinding water treatment apparatus 200, between the drain hose 201 of the grinding water treatment apparatus 200 and the tank 203, between the tank 203 of the grinding water treatment apparatus 200 and the intake pipe 320 of the first deodorizing unit 300, between the intake pipe 320 of the first deodorizing unit 300 and the exhaust pipe 350, between the exhaust pipe 350 and the intake pipe 420 of the second deodorizing unit 400, and between the exhaust pipe 350 and the processing chamber 180, so that each connection point is in a tightly sealed state, ensuring airtightness of the entire system (the entire system is sealed).

[0033] <Eyeglass lens processing equipment> In this embodiment, the eyeglass lens processing apparatus 100 will be described as an example in which the eyeglass lens is held by a lens chuck shaft 120 and the peripheral edge of the eyeglass lens (hereinafter referred to as lens LE) is processed by a processing tool unit 140 and a grindstone 150. The eyeglass lens processing apparatus 100 includes a housing 101, a monitor 102, a lens processing mechanism unit 110, etc.

[0034] The housing 101 is an exterior cover that houses components such as the processing mechanism unit 110, the lens refractive surface shape measuring unit 160, the nozzle 170, and the processing chamber 180, which will be described later. The housing 101 may also have an openable window (not shown) for inserting and removing the eyeglass lens into and from the processing chamber 180. The monitor 102 in this embodiment is configured as a display with a touch panel function. That is, in this embodiment, the monitor 102 functions as an operation unit (controller). Note that the monitor 102 does not have to be a touch panel type, and the monitor 102 and the operation unit may be provided separately. In this case, at least one of a mouse, a joystick, a keyboard, a mobile terminal, etc. may be used as the operation unit.

[0035] The processing mechanism section 110 includes a lens chuck shaft 120, a carriage 130, a processing tool unit 140, a grindstone 150 which is an example of a processing tool, a moving unit 135, and the like.

[0036] The lens chuck shaft (lens holding shaft) 120 holds the lens LE. The lens chuck shaft 111 includes a left chuck shaft 120L and a right chuck shaft 120R. The moving unit 135 is configured to change the positional relationship between the processing position of the lens LE held by the lens chuck shaft 120 and the processing tool (e.g., grindstone 150) in a three-dimensional manner. For example, the moving unit 135 includes a rotation unit 135A, an X-moving unit 135B, and a Y-moving unit 135C. The rotation unit 135A is configured to rotate the lens LE by rotating the lens chuck shaft 120. The X-moving unit 135B is configured to move the lens chuck shaft 120, which holds the lens LE, in its axial direction (X direction). The Y movement unit 135C is configured to move the lens chuck shaft 120 in a direction (Y direction) that changes the inter-axial distance between the lens chuck shaft 120 and the rotation axis of the processing tool (e.g., grinding wheel rotation axis 151, second processing tool rotation axis 147, rotation axis 145).

[0037] The moving unit 135 includes a carriage 130. The carriage 130 holds a lens chuck shaft (lens rotation shaft) 120. The carriage 130 is moved in the X and Y directions by an X moving unit 135B and a Y moving unit 135C, thereby moving the lens chuck shaft 120 relative to the processing tool unit 140 and the grindstone 150. The carriage 130 is composed of a left arm 132L and a right arm 132R. The left chuck shaft 120L of the lens chuck shaft 120 is rotatably and coaxially held by the left arm 132L of the carriage 130. The right chuck shaft 120R of the lens chuck shaft 120 is rotatably and coaxially held by the right arm 132R of the carriage 130. A rotation transmission mechanism such as a gear (not shown) rotates in the right arm 132R of the carriage 130 when driven by a rotation unit 135A. The left and right chuck shafts 120L and 120R rotate synchronously with each other via a rotation transmission mechanism. A motor (not shown) is attached to the right arm 132R, and the right chuck shaft 120R moves toward the left chuck shaft 120L when driven by the motor (not shown). This causes the lens LE to be held by the left and right chuck shafts 120L and 120R.

[0038] The processing tool unit 140 processes the peripheral edge of the lens clamped by the lens chuck shaft 120. For example, the processing tool unit 140 is disposed behind the carriage 130. The processing tool unit 140 includes a motor 141, a roughing tool 142, a chamfering tool 143, a holder 144, a rotation shaft 145, a first processing tool rotation shaft 146, a second processing tool rotation shaft 147, etc. The motor 141 moves the processing tool unit 140 to a processing position where the peripheral edge of the lens LE is processed. The roughing tool 142 roughly processes the peripheral edge of the lens LE. For example, a cutter is used as the roughing tool 142 in this embodiment, but an end mill may also be used. The chamfering tool 143 chamfers the corners of the edge of the lens LE. For example, a grinding wheel is used as the chamfering tool 143. The holder 144 is connected to the roughing tool 142, the chamfering tool 143, and the rotating shaft 145 and holds the roughing tool 142 and the chamfering tool 143. The rotating shaft 145 rotates the holder 144 by a motor (not shown). The first processing tool rotating shaft 146 is connected to the chamfering tool 143. The first processing tool rotating shaft 146 is rotatably held inside the rotating shaft 145. Furthermore, the chamfering tool 143 rotates when the first processing tool rotating shaft 143 is rotated by a motor (not shown). The second processing tool rotating shaft 147 is connected to the roughing tool 142. The second processing tool rotating shaft 147 is connected to the motor (not shown) of the first processing tool rotating shaft 146 via a connecting member (not shown). In this embodiment, the second processing tool rotating shaft 147 is located at a position different from the drive shaft of the motor (not shown) of the first processing tool rotating shaft 146. That is, the rotation of the drive shaft of the motor (not shown) of the first processing tool rotation shaft 146 is transmitted to the second processing tool rotation shaft 147 via a one-way clutch (not shown), a bearing (for example), etc. As a result, the rotation of the motor (not shown) of the first processing tool rotation shaft 146 is transmitted to the second processing tool rotation shaft 147, and the rough processing tool 142 is rotated.

[0039] The grindstone 150 is used as a processing tool for grinding the lens LE. The grindstone 150 is attached to a grindstone rotation shaft 151. The grindstone rotation shaft 151 is rotated by a motor 152. The peripheral edge of the lens clamped by the lens chuck shaft 120 is processed by being pressed against the grindstone 150, which is rotated by the drive of the motor 152. For example, the grindstone 150 includes a roughing grindstone, a finishing grindstone, etc. For example, the finishing grindstone includes a processing surface for forming a bevel on the peripheral edge of the lens LE after roughing, and a flat finishing processing surface.

[0040] Furthermore, a lens refractive surface shape measuring unit 160 is disposed inside the eyeglass lens processing apparatus 100. The lens refractive surface shape measuring unit 160 measures the shape of the refractive surface (the front and rear surfaces of the lens) of the lens LE held by the lens chuck shaft 120.

[0041] The configurations of the processing mechanism unit 110 and the lens refractive surface shape measuring unit 160 can be those described in Japanese Patent Application Laid-Open No. 2017-177234, so please refer to this for details.

[0042] Furthermore, during peripheral processing of the lens LE, the processed portion (ground portion) of the lens LE is cooled by supplying (spraying) water (grinding water) from the nozzle 170 to the lens LE and the grinding portion of the processing tool. Furthermore, processing debris generated during processing is washed away to the bottom of the processing chamber 180 by the water supplied from the nozzle 170. A drainage hose 201, which is a drainage path through which wastewater containing processing debris is discharged, is connected to the bottom of the processing chamber 180.

[0043] An exhaust pipe 350 of the first deodorizing unit 300, which will be described later, is connected to the connection port 190. The connection port 190 is provided on the upper side wall of the processing chamber 180. The connection port 190 is also provided above the nozzle 170 that sprays the grinding water (or cleaning water).

[0044] <Grinding water treatment equipment> The grinding water treatment device 200 separates wastewater discharged from the processing chamber 180 of the eyeglass lens processing device 100 into processing chips and water (grinding water). The grinding water treatment device 200 also guides the separated water to the nozzle 170 of the eyeglass lens processing device 100 via a water supply hose 208. Note that the water separated from the processing chips by the grinding water treatment device 200 may not necessarily be completely separated from the processing chips. The grinding water treatment device 200 includes a drain hose 201, a filter 202, a tank 203, a lid 204, a water intake hose 205, a water intake filter 206, a water intake pump 207, a water supply hose 208, etc.

[0045] The drain hose 201 is connected to the processing chamber 180 of the eyeglass lens processing apparatus 100. The drain hose 201 extends to the tank 203 side of the grinding water treatment apparatus 200. The filter 202 is detachably attached to the end of the drain hose 201 extending into the tank 203. The filter 202 also serves as a bag for collecting processing waste. The tank 203 stores water. The lid 204 covers the top of the tank 203. The water suction hose 205 is attached to the lid 204 and extends downward. The water suction filter 206 is mesh-shaped. The water suction filter 206 is attached to the lower end of the water suction hose 205. The upper end of the water suction hose 205 is connected to a water suction pump 207. A water supply hose 208 is connected to the water suction pump 207. The other end of the water supply hose 208 is connected to the nozzle 170 of the eyeglass lens processing apparatus 100. The connection port 209 is connected to an intake pipe 320 of the first deodorizing unit 300, which will be described later. The connection port 209 is provided on the upper side wall of the tank 203.

[0046] Wastewater discharged from the processing chamber 180 is introduced into a tank 203 via a drainage hose 201 of a grinding water treatment device 200. Processing waste is collected by a filter 202 attached to the end of the drainage hose 201 extending into the tank 203. Water stored in the tank 203 is taken in from the tank 203 side via a water suction hose 205 by driving a water suction pump 207. The water is guided to a nozzle 170 of the eyeglass lens processing apparatus 100 via a water supply hose 208, and is sprayed (supplied) by the nozzle 170 to the processing portion of the lens LE in the processing chamber 180. In this way, the eyeglass lens periphery processing deodorizing system repeats the above circulation.

[0047] In this embodiment, grinding water supply means 210 for supplying grinding water to the processing portion of the lens LE is composed of a water suction hose 205, a water suction filter 206, a water suction pump 207, a water supply hose 208, a nozzle 170, etc. Furthermore, odors generated in the processing chamber 180 are flowed via a drainage hose 201 into a space 211 in the tank 203 (the space between the grinding water stored in the tank 180 and the lid 204).

[0048] The grinding water treatment device 200 of this embodiment is not limited to the above configuration. For example, the grinding water treatment device may be a centrifugal separator that separates water from machining chips. Also, for example, the drain hose 201 may be connected to a water intake pump equipped with a filter function.

[0049] <First deodorizing unit> The first deodorizing unit 300 includes a housing 310, a first passage 600 including an intake pipe 320, a first deodorizing member 330, a blower 340, an exhaust pipe 350, and the like. The first passage 600 is configured to deliver odors from the processing chamber 180 to the first deodorizing member 330. In the embodiment shown in FIG. 1, the first passage 600 is configured by a drain hose 201 connected to the processing chamber 180, a space 211 in the tank 203, and an intake pipe 320. In this embodiment, the drain hose 201 of the grinding water treatment device 200 is connected to the processing chamber 180 of the eyeglass lens processing apparatus 100. Therefore, odors generated during processing of eyeglass lenses from the processing chamber 180 may reach the inside of the tank 203. Therefore, the processing chamber 180 and the tank 203 can be considered as the same space. Of course, the first passage 600 may also be configured by directly connecting the intake pipe 320 to the processing chamber 180.

[0050] The housing 310 is an exterior cover that houses components such as a first deodorizing member 330 and a blower 340, which will be described later.

[0051] The intake pipe 320 is used to suck odors generated in the processing chamber 180 into the first deodorizing unit 300 .

[0052] The first deodorizing member 330 decomposes and deodorizes odor components sucked into the housing 310. As an example, the first deodorizing member 330 is a photocatalyst. Note that the first deodorizing member 330 may also be a member that adsorbs odor components sucked into the housing 310 (for example, an ozone decomposition catalyst, etc.).

[0053] The blower 340 serves as an intake section, sucking in odors from the intake pipe 320 and directing the airflow to the exhaust pipe 350. The blower 340 includes a fan 341 and a drive section (e.g., a motor 342) that rotates the fan 341. When the fan 341 is rotated by the motor 342, odors generated inside the eyeglass lens processing apparatus 100 and the grinding water treatment device 200 are sucked into the first deodorizing unit 300 via the first path 600, which includes the intake pipe 320, and then passed through the first deodorizing member 330 and directed to the exhaust pipe 350.

[0054] The exhaust pipe 350 exhausts the gas that has passed through the first deodorizing member 330 from the first deodorizing unit 300. The other end of the exhaust pipe 350 is connected to a connection port 190 provided in the processing chamber 180 of the eyeglass lens processing apparatus 100. In this embodiment, the exhaust pipe 350 is connected to the processing chamber 180 as a third path 800 for returning the gas that has passed through the first deodorizing member back to the processing chamber 180.

[0055] In addition, in order to ensure airtightness of the flow path in the first deodorizing unit 300, the connection point 360 between the housing 310 and the intake pipe 320 and the connection point 370 between the housing 310 and the exhaust pipe 350 may be structured to improve airtightness by fitting together (for example, a fitting structure using gaskets, etc.).

[0056] <Second deodorizing unit> The second deodorizing unit 400 includes a housing 410, a second path 700 including an intake pipe 420, a second deodorizing member 430, a blower 440, an exhaust port 450, a switching valve 460, and the like.

[0057] Housing 410 is an exterior cover that houses components such as second deodorizing member 430 and blower 440, which will be described later.

[0058] The intake pipe 420 is used to suck odors generated in the processing chamber 180 into the second deodorizing unit 400. In this embodiment, the intake pipe 420 is connected to the exhaust pipe 350 connected to the processing chamber 180 as a second path 700 for sending odors from the processing chamber 180 of the eyeglass lens processing apparatus 100 to the second deodorizing member 430. In the embodiment of FIG. 1, a valve 461 of a switching valve 460 (described later) closes the front pipe portion 350a of the exhaust pipe 350 and opens the intake pipe 420, so that the rear pipe portion 350b of the exhaust pipe 350 connected to the processing chamber 180 is connected to the intake pipe 420. That is, in the embodiment of FIG. 1, the second path 700 is composed of the intake pipe 420 and the rear pipe portion 350b of the exhaust pipe 350. Of course, the second path 700 may be configured such that the intake pipe 420 is directly connected to the processing chamber 180 without sharing the rear pipe portion 350b of the exhaust pipe 350.

[0059] The second path 700 in the embodiment of Figure 1 is configured to share the rear pipe portion 350b of the exhaust pipe 350, which is an example of the third path 800 connected to the processing chamber 180, so there is no need to increase the number of connection ports 190 provided in the processing chamber 180.

[0060] The second deodorizing member 430 adsorbs and deodorizes odor components sucked into the housing 410. The second deodorizing member 430 may be any member that has a faster deodorizing effect than the first deodorizing member 330 and does not require replacement. As an example, the second deodorizing member 430 is activated carbon. The second deodorizing member 430 may also be a member (such as a catalyst) that decomposes odor components sucked into the housing 410.

[0061] The blower 440 serves as an intake section, sucking in odors from the intake pipe 420 and directing the airflow to the exhaust port 450. The blower 440 includes a fan 441 and a drive section (e.g., a motor 442) that rotates the fan 441. When the motor 442 rotates the fan 441, odors generated in the processing chamber 180 of the eyeglass lens processing apparatus 100 are sucked from the exhaust pipe 350 connected to the processing chamber 180 through the intake pipe 420 into the second deodorizing unit 400, and then passed through the second deodorizing member 430 and directed to the exhaust port 450.

[0062] The exhaust port 450 allows the gas that has passed through the second deodorizing member 330 to be discharged from the second deodorizing unit 400 .

[0063] The switching valve 460 is provided as an example of a setting means for setting the delivery path for delivering the odor from the processing chamber 180 to the first path 600 and the second path 700. The switching valve 460 includes a valve 461 and a drive unit (e.g., a motor 462) that drives the valve 461.

[0064] 2 and 3 are diagrams showing the direction of airflow when the odor delivery path from the processing chamber 180 is set by the switching valve 460. Fig. 2 is a diagram showing the direction of airflow when set to the first path 600 and the third path 800. Fig. 3 is a diagram showing the direction of airflow when set to the second path 700. The bold arrows shown in the diagrams indicate the direction of airflow.

[0065] For example, when the odor delivery paths from the processing chamber 180 are set to the first path 600 and the third path 800, the valve 461 of the switching valve 460 is positioned to block the intake pipe 420. The odor is sucked from the tank 203 of the grinding water treatment device 200 (including the processing chamber 180 of the eyeglass lens processing device 100) through the intake pipe 320 into the first deodorizing unit 300 in the direction shown by the arrow in FIG. 2, passes through the first deodorizing member 330, is guided to the exhaust pipe 350, and is then sent back to the processing chamber 180 from the exhaust pipe 350, which is the third path 800. In this way, the delivery paths are set to the first path 600 and the third path 800. In this way, gas can be circulated within the sealed deodorizing system 10.

[0066] On the other hand, for example, when the odor delivery path is set to the second path 700, the valve 461 of the switching valve 460 is positioned to close the intake pipe 320. The odor is sucked into the second deodorizing unit 400 through the intake pipe 420, which also serves as the rear pipe section 350b that is part of the exhaust pipe 350, in the direction shown by the arrow in Figure 3 from the processing chamber 180, and then passes through the second deodorizing member 430 and is led to the exhaust port 450. The deodorized gas is discharged to the outside of the deodorizing system 10.

[0067] In addition, in order to ensure airtightness of the flow path in the second deodorizing unit 400, the connection point 470 between the housing 410 and the intake pipe 420 may have a structure that improves airtightness by fitting together (for example, a fitting structure using a packing or the like).

[0068] <Control unit> FIG. 4 is a block diagram showing a control system of the deodorizing system 10. The deodorizing system 10 according to the present disclosure includes a control unit 60 for controlling the operation of the eyeglass lens processing apparatus 100, the grinding water treatment device 200, the first deodorizing unit 300, and the second deodorizing unit 400. In this embodiment, the control unit 60 functions as part of the setting means. Of course, the control unit for controlling the operation of the eyeglass lens processing apparatus 100, the control unit for controlling the operation of the grinding water treatment device 200, the control unit for controlling the operation of the first deodorizing unit 300, and the control unit for controlling the operation of the second deodorizing unit 400 may be provided separately. The control unit 60 controls the driving of electric elements such as motors included in each component. The control unit 60 may be realized by a general CPU (processor), ROM, RAM, etc. The control unit 60 also includes a memory 70 as a storage unit. The memory 70 may be a non-transitory storage medium capable of retaining its contents even when the power supply is interrupted. For example, the memory 70 may be a hard disk drive, a flash ROM, a removable USB memory, or the like.

[0069] <Control action> The operation of the deodorization system 10 having the above-described configuration will be described. First, the operation of processing the periphery of the lens LE by the eyeglass lens processing apparatus 100 will be briefly described.

[0070] <Preparation before eyeglass lens processing> For example, an operator acquires the contour shape of the rim of an eyeglass frame measured using a lens shape measuring device (not shown). For example, the lens shape data may be acquired by retrieving data stored in the memory 70. For example, after acquiring the lens shape data, the operator sets (inputs) processing conditions for processing the periphery of the lens LE using the monitor 102 (see FIG. 1). For example, the control unit 60 creates layout data for locating the optical center position of the lens LE relative to the lens shape based on the set (input) processing conditions. For example, the layout data includes the distance FPD between the left and right lens centers, the interpupillary distance PD, and the height distance of the optical center relative to the lens shape center. Furthermore, the processing conditions input include the lens material, the frame type (e.g., metal, cell, rimless, etc.), the lens periphery processing type (e.g., beveling, flat processing, groove processing, etc.), whether or not mirror processing is performed, etc.

[0071] For example, an operator holds the lens LE on the lens chuck shafts 120 (120L, 120R) and starts the operation of the eyeglass lens processing apparatus 100 using the monitor 102. For example, when the control unit 60 receives a signal to start the operation, it executes an eyeglass lens shape measurement program and starts measuring the shape of the lens LE by the lens refractive surface shape measuring unit 160 before processing the peripheral edge of the lens LE. As a result, the control unit 60 acquires the outer shape of the lens LE and stores it in the memory 70.

[0072] When the measurement of the refractive surface shape of the lens LE is completed, the control unit 60 obtains control data for roughing and finishing for processing the periphery of the lens LE. For example, the control data for roughing is obtained as a roughing trajectory, which is a trajectory that is a predetermined amount outside the finishing trajectory based on the lens shape data. Furthermore, if beveling is set, the bevel trajectory is calculated based on the lens shape data, layout data, and the results of lens shape measurements of the front and rear surfaces of the lens.

[0073] <Rough processing> Once the control unit 60 obtains the control data, it starts roughing. A method similar to that described in the prior art can be used to perform roughing (see, for example, Japanese Patent Application Laid-Open No. 2017-177234). For example, the control unit 60 drives the motor 141 of the processing tool unit 140 to move the roughing tool 142 of the processing tool unit 140 to a roughing position. For example, the control unit 60 controls the drive of the X-axis moving unit 135B and the Y-axis moving unit 135C to bring the lens LE and the roughing tool 142 closer together. For example, while rotating the lens LE using the rotation unit 135A, the control unit 60 controls the drive of the Y-axis moving unit 135C based on the roughing trajectory to change the positional relationship of the lens LE with respect to the roughing tool 142, thereby roughing the lens LE. Furthermore, when starting roughing, the control unit 60 drives the water suction pump 307 of the grinding water treatment device 300 to spray water from the nozzle 170.

[0074] <Finishing> Once the roughing is complete, the process moves to finishing. For example, if beveling is set, the control unit 60 calculates the bevel path (radius vector information and information on the position of the bevel apex in the direction of the axis L1) based on the target lens shape data, layout data, and lens shape measurement results for the front and rear surfaces of the lens. Then, the drive of the moving unit 135 is controlled based on the calculated bevel path, and the periphery of the lens LE after roughing is beveled by the finishing tool 163c. Furthermore, if chamfering is set, the corners of the lens LE that have been finished are chamfered by the chamfering tool 143. Then, once the periphery of the lens LE has been finished by the grindstone 150 or the like, the spraying (supplying) of water (grinding water) from the nozzle 170 is stopped.

[0075] Next, the operation of setting the discharge path for discharging odor from the processing chamber 180 to at least one of the first path 600 of the first deodorizing unit 300 and the second path 700 of the second deodorizing unit 400 during the processing operation of the lens LE by the eyeglass lens processing apparatus 100 as described above will be explained using the timing chart of Figure 5.

[0076] In this embodiment, in the preparation step before rough processing, a state in which the eyeglass lens is waiting for peripheral processing by a processing tool is designated as a first state P1. In addition, from the start of rough processing to the end of finish processing, the state is designated as a second state P2, and from the end of finish processing to the start of rough processing of the next lens LE, the state is again designated as the first state P1.

[0077] <Deodorization by the first deodorizing unit> In the deodorization system 10 of the present disclosure, in the first state P1 in which the system is waiting for the processing tool to process the periphery of the eyeglass lens, the first deodorizing member 330 of the first deodorizing unit 300 performs deodorization.

[0078] When power is supplied to the eyeglass lens processing apparatus 100, the control unit 60 drives the motor 342 of the blower 340 provided in the first deodorizing unit 300 to rotate the fan 341. The control unit 60 also drives the motor 462 of the switching valve 460 provided in the second deodorizing unit 400 to drive the valve 461 to close the path to the intake pipe 420. For example, the gas inside the deodorizing system 10 generates an airflow when the fan 341 is rotated by the motor 342, and the gas is circulated within the sealed deodorizing system 10 as shown in FIG. 2. As a result, the odor delivery path is set to the first path 600, and deodorization by the first deodorizing member 330 begins.

[0079] For example, even in the first state P1, odors may be generated from processing debris remaining in the processing chamber 180 of the eyeglass lens processing apparatus 100, or from processing debris and grinding water in the tank 203 of the grinding water treatment device 200, and when an openable window (not shown) in the processing chamber 180 is opened, the odors may leak outside the deodorizing system 10. Therefore, even in the first state P1, odors generated in the processing chamber 180 can be deodorized by performing deodorization with the first deodorizing unit 300. Furthermore, by circulating the gas in the processing chamber 180 through the third path 800, the odors can be passed through the first deodorizing member 330 multiple times, thereby effectively deodorizing the odors in the processing chamber 180.

[0080] <Deodorization by the second deodorizing unit> In the deodorizing system 10 of the present disclosure, deodorizing is performed by the second deodorizing member 430 of the second deodorizing unit 400 in the second state P2 (see FIG. 5) of periphery processing, which includes at least rough processing of the periphery of the eyeglass lens with the processing tool.

[0081] For example, the control unit 60 drives the motor 442 of the blower 440 provided in the second deodorizing unit 400 to rotate the fan 441 based on a predetermined operation signal of the eyeglass lens processing apparatus 100. The control unit 60 also drives the motor 462 of the switching valve 460 provided in the second deodorizing unit 400 to drive the motor 462 so as to close the path to the exhaust pipe 350 connected to the first deodorizing unit 300. Furthermore, the control unit 60 stops driving the blower 340 of the first deodorizing unit 300. This sets the odor delivery path to the second path 700. Furthermore, as shown in FIG. 3, the circulation of gas within the deodorizing system 10 stops, gas begins to flow into the second deodorizing unit 400, and deodorization by the second deodorizing member 430 begins.

[0082] For example, a trigger signal indicating the start of processing of the lens LE (e.g., the start of rough processing) can be used as the predetermined operation signal (a signal for setting the second path 700 as the sending path for sending out the odor from the processing chamber 180). Of course, a measurement start signal or a measurement end signal for the lens LE by the lens refractive surface shape measuring unit 160 may also be used as the predetermined operation signal. Furthermore, a signal indicating that the lens chuck shaft 120 holds the lens LE, a signal indicating that the rough processing tool 142 has come into contact with the lens LE, etc. may also be used as the predetermined operation signal.

[0083] For example, when processing the periphery of an eyeglass lens with a processing tool, as in the second state P2, a large amount of bad odor is generated due to components contained in the eyeglass lens during processing. Therefore, by deodorizing with the second deodorizing member 430, which has a more immediate deodorizing effect than the first deodorizing member 330, the deodorizing effect can be improved. Furthermore, by deodorizing with the second deodorizing member 430, which requires replacement, only in the second state P2, the frequency of replacement of the deodorizing member is reduced, thereby reducing the effort required by the worker to replace the deodorizing member and reducing the cost associated with replacing the deodorizing member.

[0084] For example, when the control unit 60 receives a signal indicating that the finishing process has ended, it drives the motor 342 of the blower 440 provided in the second deodorizing unit 400 for a predetermined time Q1 and then stops the motor 342. The control unit 60 also drives the motor 462 of the second deodorizing unit 400 and drives the valve 461 to close the path to the intake pipe 420. The control unit 60 also drives the motor 342 of the first deodorizing unit 300 to rotate the fan 341. This causes the deodorizing system 10 to return to the first state P1, and deodorization by the first deodorizing member 330 of the first deodorizing unit 300 begins. The first state P1 is maintained until the next predetermined operation signal (a signal for setting the second path 700 as the path for sending out the odor from the processing chamber 180) is received. Of course, the control unit 60 may also perform these controls upon receiving a signal indicating that the finishing process has ended.

[0085] As described above, the deodorizing system for eyeglass lens periphery processing of the present disclosure includes an eyeglass lens processing device having a processing chamber in which processing tools for processing the periphery of eyeglass lenses are placed, and a deodorizing unit that deodorizes odors generated during the processing of eyeglass lenses. The deodorizing unit includes a first deodorizing unit having a first deodorizing member that deodorizes odors and a first path for sending odors from the processing chamber to the first deodorizing member, a second deodorizing member that has a more immediate deodorizing effect than the first deodorizing member and requires replacement, and a second path that is at least partially different from the first path and sends odors from the processing chamber to the second deodorizing member, and the deodorizing system includes a setting means for setting the sending path for sending odors from the processing chamber to at least one of the first path and the second path, depending on the control state of the eyeglass lens processing device. Conventional deodorizing devices use replaceable deodorizing members that have a more immediate deodorizing effect. However, as the deodorizing performance of these deodorizing members approaches its odor absorption limit, they begin to decline, necessitating replacement. Therefore, by switching the deodorizing member in use to deodorize odors depending on the control state (processing state) of the eyeglass lens processing device, the decline in deodorizing performance is suppressed while reducing the number of times the deodorizing member is used (wear and tear). This reduces the frequency with which replacement deodorizing members are required, reducing the time and effort required by workers to replace the deodorizing members and reducing the costs associated with replacing them. Furthermore, fewer deodorizing members are discarded, contributing to environmental friendliness.

[0086] In the deodorizing system for eyeglass lens periphery processing of the present disclosure, the setting means sets the delivery path to the first path in a first state, in which the eyeglass lens is waiting for periphery processing by a processing tool, and sets the delivery path to the second path or to both the first and second paths in a second state, in which the eyeglass lens is being controlled to be periphery processed by the processing tool. For example, in the second state, a large amount of malodor is generated due to components contained in the eyeglass lens during lens processing. On the other hand, in the first state, malodor is generated from processing waste, grinding water, etc. after processing, but the malodor is less likely to be generated compared to the second state. Therefore, for example, by setting the path according to the control state (processing state) of the eyeglass lens processing device (in other words, by using different deodorizing members depending on the malodor generation status), the use of the second deodorizing member that requires replacement (i.e., odor absorption) can be reduced. This can extend the deodorizing function of the second deodorizing member.

[0087] In the deodorizing system for eyeglass lens periphery processing of the present disclosure, the deodorizing unit has a third path for returning the odor-containing gas that has passed through at least the first deodorizing member back to the processing chamber, and by setting the delivery path to the first path, the odor-containing gas that has not been deodorized by the first deodorizing member is returned to the first deodorizing member and circulated between the processing chamber and the first deodorizing member. This allows the gas in the processing chamber to circulate, and the odor can be passed through the first deodorizing member multiple times, thereby effectively deodorizing the odor in the processing chamber.

[0088] The deodorizing system for eyeglass lens peripheral processing of the present disclosure further includes a circulating grinding water supply device that uses a pump to draw up grinding water stored in a tank and supply it to the eyeglass lens processing device, and that returns grinding water discharged from the processing chamber of the eyeglass lens processing device to the tank for reuse, and at least the first path is configured to send odors from the processing chamber to the first deodorizing member via the circulating grinding water supply device. For example, eyeglass lens odors are also generated by processing waste, grinding water, etc., after lens processing by the eyeglass lens processing device. Therefore, by passing the water through the circulating grinding water supply device, odors remaining in the tank can also be deodorized.

[0089] <Example of transformation> In the deodorizing system 10 of this embodiment, in the first state, in which the system is waiting for the processing tool to process the periphery of the eyeglass lens, the path for sending out the odor from the processing chamber is set to the first path 600, and in the second state, in which the processing tool is controlling the periphery of the eyeglass lens, the path for sending out the odor from the processing chamber is set to the second path 700. However, the present invention is not limited to this. For example, in the second state, in which the processing tool is controlling the periphery of the eyeglass lens, the first path 600 and the second path 700 may be set. In other words, in the second state, in which the processing tool is controlling the periphery of the eyeglass lens, the first deodorizing member 330 of the first deodorizing unit 300 and the second deodorizing member 430 of the second deodorizing unit 400 may be used together to deodorize the odor.

[0090] 6 is a diagram showing the direction of airflow when first path 600 and second path 700 are set. The bold arrows in the diagram indicate the direction of airflow. Here, switching valve 460 of second deodorizing unit 400 will be described as being configured to drive valve 461 and motor 462 to open and close the path to intake pipe 420.

[0091] For example, when the control state of the eyeglass lens processing apparatus 100 becomes the first state, the control unit 60 drives the motor 462 of the switching valve 460 and drives the valve 461 to close the path to the intake pipe 420. That is, in the first state in the modified example of Fig. 6, similar to the case of Fig. 1, a first path 600 is set which is composed of the drain hose 201 connected to the processing chamber 180, the space 211 of the tank 203, and the exhaust pipe 320. In addition, the exhaust pipe 350 (front pipe section 350a and rear pipe section 350b) is configured as a third path 800 for returning the gas which has passed through the first deodorizing member back to the processing chamber 180.

[0092] On the other hand, when the control state of the eyeglass lens processing apparatus 100 becomes the second state, the control unit 60 drives the motor 462 of the switching valve 460 provided in the second deodorizing unit 400 to block the path of the rear pipe section 350b of the exhaust pipe 350 and open the path to the intake pipe 420, thereby connecting the path of the intake pipe 420 to the front pipe section 350a. The control unit 60 also drives the motor 442 of the blower 440 provided in the second deodorizing unit 400 to rotate the fan 441. Furthermore, the control unit 60 also stops driving the blower 340 of the first deodorizing unit 300. Note that the control unit 60 may leave the blower 340 of the first deodorizing unit 300 driven. As a result, odors from the processing chamber 180 pass through the first deodorizing member 330 of the first deodorizing unit 300, and then pass through the second deodorizing member 430 of the second deodorizing unit 400, and odors can be deodorized by using these in combination. The deodorized gas passes through the second deodorizing member 430 and is guided to the exhaust port 450, and is discharged to the outside of the deodorizing system 10. That is, in the modified example of FIG. 6, the second path 700 is configured by a path (the front pipe portion 350a and the intake pipe 420) that sends out odors via the first path 600 and the first deodorizing member 330, and this second path 700 is set in the second state.

[0093] In the deodorizing system for eyeglass lens periphery processing of the present disclosure, the second path 700 is configured to send out odors via the first path 600 and the first deodorizing unit 330, and the setting means sets the sending path to the second path 700 configured to send out odors via the first path 600 and the first deodorizing member 330 in the second state. This allows the first and second deodorizing members to be used together to deodorize odors in a state where a large amount of bad odor is generated due to components contained in eyeglass lenses, as in the second state, thereby reducing odor adsorption to the second deodorizing member. This further reduces the use of the second deodorizing member, which requires replacement (i.e., odor adsorption).

[0094] In the above description, the deodorized gas passes through the second deodorizing member 430 and is guided to the exhaust port 450, and is discharged to the outside of the deodorizing system 10; however, this is not limiting. For example, in the second state, as shown in Fig. 7, the gas discharged from the second deodorizing unit 400 may be configured to pass from the exhaust port 450 of the second deodorizing unit 400 through the exhaust pipe 480, pass through the rear pipe portion 350b of the exhaust pipe 350, and be sent again to the processing chamber 180 of the eyeglass lens processing apparatus 100. That is, in Fig. 7, a fourth path 900 for returning the gas that has passed through the second deodorizing member 430 back to the processing chamber 180 is configured by the exhaust pipe 480 and the rear pipe portion 350b. As a result, the odor emission path from the processing chamber 180 is set to the second path 700 in Figure 7, thereby forming a circulation mechanism that returns odors that have not been completely deodorized by the second deodorizing member 430 to the second deodorizing member 430 and circulates them between the processing chamber 180 and the first deodorizing member 430.

[0095] 7, in second deodorizing unit 400, in order to ensure airtightness of the flow path, connection point 470 between housing 410 and intake pipe 420 may have a structure that improves airtightness by fitting (for example, a fitting structure using packing or the like). In this way, gas can be circulated within sealed deodorizing system 10.

[0096] This further reduces the possibility that odors that have not been completely removed by the deodorizing members will leak out of the deodorizing system 10.

[0097] 1 and 6, the switching valve 460 is used to allow the first path 600 or a portion of the exhaust pipe 350 (the front pipe section 350a or the rear pipe section 350b) to also serve as the second path 700. However, the present invention is not limited to this. The second path 700 may be provided separately from the first path 600, and the delivery path may be set to either the first path 600 or the second path 700 by switching the drive of the blowers 340 and 440, which are the intake sections of each deodorizing unit, so that the odor in the processing chamber 180 is delivered to the first deodorizing member 330 and the second deodorizing member 430.

[0098] 8 is a diagram showing an example of a configuration in which the blower 340 of the first deodorizing unit 300 and the blower 440 of the second deodorizing unit 400 are switched to drive the blower 340, and the blower 440 is switched to drive the blower 340 of the first deodorizing unit 300, and the blower 440 of the second deodorizing unit 400, so that the delivery path is set to at least one of the first path 600 and the second path 700. The bold arrows shown in the diagram indicate the direction of the airflow. The bold solid arrows indicate the direction of the airflow when the control state of the eyeglass lens processing apparatus 100 is in the first state. The bold dotted arrows indicate the direction of the airflow when the control state of the eyeglass lens processing apparatus 100 is in the second state.

[0099] 8, the second path 700 that sends odors from the processing chamber 180 to the second deodorizing member 430 has a different configuration than that of FIG. 1. That is, while the second path 700 in the embodiment of FIG. 1 is configured by the rear pipe portion 350b of the exhaust pipe 350 and the intake pipe 420 connected thereto, the second path 700 in FIG. 8 is configured to be connected to the space 211 of the tank 203. In this case, the second path 700 is configured by the drain hose 201 connected to the processing chamber 180, the space 211 of the tank 203, and the intake pipe 420.

[0100] Furthermore, the first path 600 that sends out the odor from the processing chamber 180 to the first deodorizing member 330 is configured in the same manner as in the example of Fig. 1. In the modified example of Fig. 8, the switching valve 460 is not provided midway along the exhaust pipe 350 to which the gas that has passed through the first deodorizing member 330 is sent, and a third path 800 is used as a dedicated path for returning the gas that has passed through the first deodorizing member 330 back to the processing chamber 180.

[0101] For example, when the control state of the eyeglass lens processing apparatus 100 becomes the first state, the control unit 60 drives the motor 342 of the blower 340 provided in the first deodorizing unit 300 to rotate the fan 341. As a result, odors are sucked from the tank 203 of the grinding water treatment apparatus 200 (including the processing chamber 180 of the eyeglass lens processing apparatus 100) through the intake pipe 320 into the first deodorizing unit 300 in the direction shown by the solid arrow in Fig. 8, pass through the first deodorizing member 330, and are guided to the exhaust pipe 350, and are then sent again to the processing chamber 180 from the exhaust pipe 350, which is the third path. In this way, gas can be circulated within the sealed deodorizing system 10.

[0102] For example, when the control state of the eyeglass lens processing apparatus 100 is in the second state, the control unit 60 drives the motor 442 of the blower 440 provided in the second deodorizing unit 400 to rotate the fan 441. The control unit 60 also stops driving the blower 340 of the first deodorizing unit 300. As a result, odors are sucked into the second deodorizing unit 400 through the intake pipe 420, which also serves as part of the exhaust pipe 350, in the direction shown by the dotted arrow in FIG. 8, from the processing chamber 180, and then through the second deodorizing member 430 and directed to the exhaust port 450. The deodorized gas is discharged to the outside of the deodorizing system 10.

[0103] In the second state, the blower 340 of the first deodorizing unit 300 may continue to operate, and deodorization may be performed in the first deodorizing unit 300 as well as the second deodorizing unit 400. That is, in the second state, the delivery path for delivering odor from the processing chamber 180 may be set to both the first path 600 and the second path 700.

[0104] To return to the first state, the control unit 60 stops driving the blower 440 of the second deodorizing unit 400. Thereafter, the control unit 60 drives the blower 340 of the first deodorizing unit 300. This makes it possible to properly send odor to the first deodorizing member and the second deodorizing member even without the switching valve 460.

[0105] In the modified example of Fig. 8, the intake pipe 420 of the second path 700 is configured to be connected to the space 211 of the tank 203, but it may also be configured to be directly connected to the processing chamber 180. In this case, as in the embodiment shown in Fig. 1, by setting the odor delivery path depending on the control state (processing state) of the eyeglass lens processing apparatus (in other words, by using different deodorizing members depending on the generation status of bad odors), it is possible to reduce the use of the second deodorizing member that requires replacement (i.e., odor absorption). Therefore, it is possible to extend the deodorizing function of the second deodorizing member. [Explanation of symbols]
