Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spectacle lens such as a ball milling process for cutting a spectacle lens made of glass or a plastic according to the shape of a spectacle frame or a chamfering process of the spectacle lens after cutting in a spectacle retail store. The present invention relates to a ball slicing machine that performs molding processing, and a deodorizing device for use with the ball shaving machine. Further, the present invention is used in the manufacturing process of a spectacle lens to remove an odor generated when a spectacle lens or a semi-finished blank for a lens is molded.

[0002]

2. Description of the Related Art Conventionally, spectacles are completed by molding spectacle lenses into a predetermined shape that fits a spectacle frame selected by a customer, mainly in a spectacle retail store, and then inserting the spectacle lenses into the frame. The processing of this spectacle lens is generally called edging, and after forming a lens pattern corresponding to the shape of the spectacle frame in advance or directly measuring the shape and dimensions of the frame, based on the lens pattern or measurement data. BACKGROUND ART A ball-slicing machine is widely used in which a spectacle lens is pressed against a grindstone while being rotated to perform cutting or grinding manually or automatically.
In the ball-slicing machine, the lens processing part is open to the atmosphere by simply providing a simple cover to prevent cutting dust and cutting water from scattering, and a capsule for silencing almost the entire lens processing part. There is a capsule type that is covered with.

On the other hand, as spectacle lenses, plastic lenses, which are lighter than conventional glass lenses, are often used, and recently, the lenses are lighter and thinner, and eddies on the inner surface of the lens are less likely to occur. CR-39 which was the mainstream in the past
In place of diethylene glycol bisallyl carbonate, which is called, a high refractive index lens material using a raw material containing aromatic or sulfur has been developed. This raw material containing sulfur is indispensable for manufacturing a spectacle lens having a high refractive index and a high Abbe number.

[0004]

When the above plastic lens is ball-polished, a peculiar odor is likely to be generated depending on the raw material. Particularly in the case of a lens containing a sulfur component, harmful and malodorous gases such as mercaptan and hydrogen sulfide are generated. However, conventional ball mills
Of course, in the case of the open type described above, the odor diffuses into the room as it is, and even in the case of the capsule type, the lens processing part is simply blocked by the sound deadening capsule, so that a bad odor drifts inside the room. become. Once this odor spreads in the store, it is difficult to remove it with commercially available deodorants and deodorants, and spraying the deodorant each time the lens is processed is only a hassle. It is not preferable because it gives a bad impression to customers who visit the store. Moreover, in general eyeglass stores, since a ball-slicing machine is often installed in one corner of the store without having a special processing room, the foul odor generated by the ball-slicing process is not only for workers but also for customers and other customers. There is a problem in that it gives an unpleasant sensation even to a store clerk and has a great adverse effect on sales and employment of employees.

[0005] Many eyeglass retail stores, especially those that are small-scale stores and those that are opened as tenants in commercial buildings such as department stores, and providing a special exhaust facility in the store is a heavy financial burden. Moreover, it is physically difficult due to the structure and space of the building. Moreover, such an exhaust facility usually causes a large amount of noise, which is not preferable. Further, since the eyeglass store is generally located in a downtown area or a residential area, just exhausting the air outside the store may cause an inconvenience to nearby residents and other stores.

Generally, it is most effective and important to remove odors by collecting them at the site where the odors are generated. However,
Despite this, there has been no ball milling machine that has a deodorizing function in advance in consideration of the generation of such a bad odor.

[0007] In fact, the conventional ball-slicing machine is already widespread in many eyeglass retailers, and even if a new product having a deodorizing function is developed, the ball-shaving machine is generally expensive. Therefore, it is often economically difficult for a small-scale spectacle store to replace the ball-scraping machine only for the purpose of processing a special lens because of a large cost burden.

Further, the deodorizing apparatus according to the fifth aspect of the present invention is intended to provide a deodorizing apparatus which simplifies handling and maintenance of the deodorizing filter while ensuring a sufficient deodorizing ability.

It is an object of the present invention to provide a ball shaving machine having a deodorizing function that can be performed.

In addition to this, the ball shaving machine according to claim 7 is
An object of the present invention is to provide a small-sized ball mill having a deodorizing function that can be used with a general household power source and has a low cost.

Further, in the ball shaving machine according to the present invention, the dust generated during the molding process of the spectacle lens is surely separated and removed from the odorous gas in advance, thereby prolonging the life of the deodorizing filter and for a long period of time. It is an object of the present invention to provide an easy-to-maintain ball shaving machine that can maintain a sufficient deodorizing ability.

According to the ball mill of claim 9, the dust can be easily and surely separated and removed, the maintenance is easier and the cost is low, and the intake capacity of the deodorizing section can be easily adjusted to remove the deodorizing capacity. The present invention intends to provide a ball-sliding machine that can adjust the optimum.

Further, the ball milling machine according to the tenth aspect of the present invention is intended to provide a ball milling machine which ensures a sufficient deodorizing ability and simplifies handling and maintenance of the deodorizing filter.

[0018]

The present invention is for achieving the above-mentioned object, and the contents thereof will be described below with reference to the embodiments shown in the drawings.

The deodorizing device for a ball grinding machine according to claim 1 is used for a ball grinding machine comprising a lens processing section for cutting and polishing the outer shape of a spectacle lens held by a lens holder, and a hood is used for ball grinding. At least the entire lens processing part of the machine is encapsulated in a partially opened state so that air can flow in from the outside, and odorous gas is sucked from the inside of the hood and discharged after deodorizing. And

In the deodorizing apparatus according to a second aspect of the present invention, in addition to the features of the first aspect, the deodorizing filter provided in the main body of the deodorizing device has a layer of the first adsorbent having a large ventilation resistance and a small ventilation resistance. It is characterized by having a laminated structure with a layer of the second adsorbent.

In addition to the features of claim 2 described above, the deodorizing device according to claim 3 has at least 2 upstream of the deodorizing filter of the deodorizing machine main body in order to remove dust generated during processing of the spectacle lens. A staged dust filter is installed,
Moreover, one of the dust removal filters is removable at the same time as the deodorization filter.

A deodorizing apparatus according to a fourth aspect of the present invention is characterized in that a paper filter is further disposed upstream of the dust removing filter provided on the two stages of the main body of the deodorizing machine.

The deodorizing apparatus according to a fifth aspect is characterized in that the first adsorbent of the deodorizing filter is granular activated carbon and the second adsorbent is honeycomb activated carbon.

Further, in the ball shaving machine according to a sixth aspect of the present invention, the entire lens processing part for cutting and polishing the spectacle lens held by the lens holder is partially opened so that air can flow in from the outside. It is characterized by comprising a hood that is enveloped in a state and a deodorizing portion that sucks air from the inside of the hood, deodorizes and discharges it.

According to a seventh aspect of the present invention, in addition to the characteristic features of the sixth aspect, the deodorizing portion has a first deodorizing portion having a large ventilation resistance.
It is characterized by having a deodorizing filter having a laminated structure of an adsorbent layer and a second adsorbent layer having a small ventilation resistance.

In addition to the characteristic features of claim 7 described above, the ball shaving machine according to claim 8 further includes at least two stages of dust removal upstream of the deodorizing filter in order to remove dust generated during processing of the spectacle lens. A filter is provided, and one of the dust removing filters is detachable integrally with the deodorizing filter.

According to a ninth aspect of the present invention, there is further provided a paper filter on the upstream side of the two-stage dust removing filter.

According to a tenth aspect of the present invention, the first adsorbent is granular activated carbon and the second adsorbent is honeycomb activated carbon.

[0029]

Therefore, according to the deodorizing device of the ball-sliding machine according to the first aspect, when the spectacle lens is molded by using the conventional ball-sliding machine, the odor gas generated from the lens processing portion is collected by the hood. Since the deodorizing machine body is sucked into the deodorizing machine body from the inside of the hood together with the air flow from the outside, the malodor can be removed without being diffused to the outside.

Further, according to the deodorizing device of claim 2,
In general, granular activated carbon has a large ventilation resistance and requires a strong intake capacity for the deodorizer body, but has a long life. On the other hand, the honeycomb activated carbon has a small ventilation resistance, and a good adsorption performance can be obtained even if the deodorizing unit main body has a small intake capacity, but the life is short. Therefore, by combining and stacking the first adsorbent of granular activated carbon and the second adsorbent of honeycomb activated carbon, the thickness of the deodorizing filter can be reduced and the thickness of the deodorizing unit main body can be reduced while ensuring sufficient adsorption capacity and life. The suction force can be reduced.

According to the deodorizing apparatus of the third aspect, at least one dust removing filter is always removed and attached together with the deodorizing filter, so that the odorous gas sent to the deodorizing machine body passes through the deodorizing filter. Before
The dust can be reliably separated and removed, and the deodorizing filter will not be clogged with the dust to reduce or lose the deodorizing ability.

According to the deodorizing device of the fourth aspect, the paper filter is disposable, and thereby the number of times of cleaning or replacing the dust filter on the downstream side is significantly reduced, and the thickness or the number of paper filters is reduced. By appropriately selecting, the ventilation resistance changes, and the flow velocity of the air passing through the deodorizing filter can be controlled without adjusting the suction force of the deodorizing portion.

According to the deodorizing apparatus of the fifth aspect, the granular activated carbon is inexpensive and the honeycomb activated carbon is relatively expensive, but it is excellent in moldability and easy to handle.

Further, according to the ball-slicing machine of the sixth aspect,
Odor gas generated from the lens processing part is collected in the hood when molding and processing eyeglass lenses, and it is sent to the deodorizing part together with the air flowing in from the outside by the suction force of the deodorizing part, so that the malodor is diffused to the outside. Can be removed without.

Furthermore, according to the ball-slicing machine of the seventh aspect,
As in the case of the deodorizing apparatus according to the second aspect, the thickness of the deodorizing filter can be made thinner and the intake capacity of the deodorizing portion can be made smaller while ensuring sufficient adsorption capacity and life.

According to the ball-sliding machine of the eighth aspect, as in the case of the deodorizing apparatus of the third aspect, the odorous gas sent to the deodorizing portion is generated before processing the spectacle lens before passing through the deodorizing filter. It is possible to reliably separate and remove the dust that is generated.

According to the ball milling machine of the ninth aspect, as in the case of the deodorizing apparatus of the fourth aspect, the dust removal effect is improved by the disposable paper filter, and the number of times of cleaning or replacement of the dust filter is reduced. In addition, the ventilation resistance, that is, the flow rate of air passing through the deodorizing filter can be easily controlled by appropriately selecting the thickness or the number of the paper filters.

According to the ball-slicing machine of the tenth aspect, as in the case of the deodorizing apparatus of the fifth aspect, the activated carbon is relatively easy to handle and can be obtained at low cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 schematically shows a preferred embodiment of the deodorizing device according to the present invention used for a conventional open type ball-slicing machine. This conventional type of ball slicing machine 1
Is provided with a lens processing part 3 having a transparent plastic cover 2 attached to the top of the lens so as to be openable and closable,
A grindstone 4 which is rotationally driven by an electric motor is arranged therein. In the lens processing unit 3, a spectacle lens 5 to be molded is rotatably held immediately above the grindstone 4 by using a well-known suction cup. The ball shaving machine 1 is mounted on a dedicated support base 6 which accommodates therein a tank for storing cutting water used during lens processing, a pump for circulating the cutting water, and the like.

The deodorizing device 7 of the present invention comprises a hood 9 composed of a transparent vinyl curtain mounted so as to cover the frame 8 fixed on the support base 6, and a relatively thin box type mounted on the hood 9. The deodorizer main body 10 of FIG. The frame 8 is arranged so as to surround the ball slicing machine 1 while ensuring a sufficient space so as not to hinder the operation and work thereof, and the hood 9 has front portions 11 thereof provided on both left and right sides. It can be opened and closed by an opening / closing means 12 such as a nylon zipper. And
The hood 9 has a sufficient length so that its lower end covers the upper portion of the support base 6, and a gap is secured between the hood 9 and the support base 6 over the entire circumference thereof so that air flows into the hood 9 from the outside. Is ready for you.

The deodorizer main body 10 has, for example, a centrifugal electric fan 14 inside a housing 13, and a filter storage case 15 for storing a deodorizing filter and a dust removing filter, which will be described later, is housed so that it can be put in and out from the front. Figure 2
As is well shown in FIG. 1, the filter storage case 15 has a bottom portion that is substantially entirely opened, and has a layer 16 of a first adsorbent made of, for example, granular activated carbon having a large ventilation resistance.
And a deodorizing filter 1 having a laminated structure composed of a second adsorbent layer 17 made of, for example, honeycomb activated carbon having a small ventilation resistance.
8 are arranged. In particular, the honeycomb activated carbon is very easy to handle and can be formed into a desired shape without a container and placed in a predetermined position. Immediately below the deodorizing filter 18, a dust removing filter 19 made of, for example, a non-woven fabric is arranged, and a bottom opening 20 of the filter storage case 13 is provided.
Are blocked by a net 21.

An opening 22 corresponding to the bottom opening 20 of the filter storage case 13 is formed in the bottom of the housing 11, and another dust removing filter 23 also made of a non-woven fabric is arranged immediately below the opening 22. .. Dust filter 23
Is placed on a filter holding tray 25 provided with openings 24 corresponding to the openings 20 and 22, and the filter holding tray 25 is detachable by a rail 26 formed around the opening 22 on the bottom surface of the housing 13. It is attached. In this way, the dust filter for pretreatment of odorous gas
By arranging the filters in one step, even if one of the dust removing filters 23 is removed for cleaning and then not attached, the other dust removing filter 19 cannot be removed unless the dust removing filter 19 and the deodorizing filter 18 are removed at the same time. Since the deodorizing filter 18 is arranged, there is no risk that the deodorizing filter 18 will be clogged with dust and lose its deodorizing function. The opening 24 of the tray 25 is prevented from coming off by a net 27. In the filter holding tray 25, a disposable paper filter (not shown) can be arranged below the dust removal filter 23. Since the dust is removed to some extent by the paper filter, the dust removing filters 23 and 19 become slower to be soiled, the number of times of cleaning is reduced, and the maintenance becomes easier.

The deodorizer main body 10 communicates with the inside of the hood 9 by arranging the opening 22 of the deodorizer main body 10 in alignment with the opening formed in the upper portion of the hood 9. When the spectacle lens 5 is molded by the ball shaving machine 1, the lens processing unit 2
At, gas containing odor is generated. This gas is collected in the hood 9, and when the electric fan 14 is operated, the gas is deodorized from the upper part of the hood 9 together with the flow of air that flows from the outside through the gap between the hood 9 and the support base 6. It is sucked into the machine body 10. As for the odorous gas sucked in this way, first, the dust generated by the molding process of the spectacle lens 5 is the dust filter 2 and the paper filter.
Deodorized filter 18 separated and removed by 3, 19
It is adsorbed and deodorized by passing through. The air that does not contain the deodorized odorous gas component is discharged into the atmosphere through an exhaust port (not shown) provided in the rear portion of the housing 13.

It is known that the adsorption rate of the odorous gas component generally increases as the contact time between the gas and the adsorbent increases, and the deodorizing effect increases. For that purpose, it is necessary to increase the distance for the odor to pass through the adsorbent and to reduce the flow velocity thereof. On the other hand, if the flow velocity of the sucked air is too slow, the odor will leak to the outside through the gap between the hood 9 and the support 6. As a condition for preventing the odor from leaking to the outside, it is necessary to make the surface velocity of the air flowing into the deodorizing filter 0.5 m / sec or more. For that purpose, when the area of the gap is assumed to be 300 cm ^2. In addition, the electric fan has an air volume (displacement) of 1.0 m ³
It has been found that it is necessary to have a capacity of not less than / min. Further, in order to sufficiently absorb the odor, it is necessary to limit the surface speed within 1.0 m / sec at the maximum.

In the above-described embodiment, the electric fan 14 is installed by mounting the paper filter having the appropriate thickness and number of sheets under the dust removing filter 23 of the filter holding tray 25.
The suction force can be adjusted without changing the number of rotations. Therefore, since the frequencies of commercial power sources are different between East Japan and West Japan, when the same electric fan is used, the number of revolutions varies depending on the region of use, and the flow rate of the sucked odorous gas is too fast or too slow. Even if the specification of the electric fan is not changed according to the region or the rotation speed control means according to the power source is not provided, the air resistance can be changed by the number of paper filters, and the flow velocity can be controlled easily and at low cost.

The granular activated carbon used for the first adsorbent 16 of the deodorizing filter 18 has a long adsorption life because it has a large adsorption capacity, but has a large ventilation resistance compared to its adsorption capacity. It is necessary to increase the output of the fan, which leads to an increase in the size and power consumption of the entire deodorizer. On the other hand, since the honeycomb activated carbon used for the second adsorbent 17 has a small pressure loss and a high adsorption efficiency, it can obtain sufficient deodorizing performance even if it is thin, but has a small adsorption capacity and a short life. For this reason, the honeycomb activated carbon alone requires a large-volume deodorizing filter, the deodorizing machine as a whole becomes large, and the deodorizing filter must be frequently replaced, which increases the running cost. For example, when the flow rate of odorous gas is 1 m ^{3 /} min, in order to obtain sufficient deodorizing performance,
The granular activated carbon alone required a thickness of 10 cm, and the honeycomb activated carbon alone required a thickness of 20 cm.

As a result of the deodorizing filter 18 having a laminated structure of honeycomb activated carbon and granular activated carbon as in the present invention, it is possible to obtain the same adsorption capacity with the thickness of each 5 cm, and with a general household power source. Sufficient suction power could be obtained using a usable 55 W electric fan. Using the deodorizer configured in this way, the outer diameter is 80 mm and the total height is 8 mm.
The thiourethane resin-based plastic lens containing the sulfur component is attached to a conventional ball-slicing machine, and the outer shape is 4 cm ×
Grinding was carried out with a diamond grindstone so as to make a 5 cm square, but the peculiar odor peculiar to this plastic lens could be completely removed.

FIG. 3 shows another embodiment of the deodorizing device of the present invention which is used for the conventional capsule type ball shaving machine 28. The ball-slicing machine 28 is used for the eyeglass lens 2
The lens processing portion 31 that holds 9 and rotates / turns the grindstone 30 for cutting / grinding is covered with a silencing capsule 32 that can be opened and closed. An upper frame 33 having the same structure as the frame 8 of the first embodiment shown in FIG.
A frame structure composed of a lower frame 34 for supporting the same and a lower frame 34 for supporting the frame structure is arranged. It is mounted so as to sufficiently enclose at least the upper portion having the lens processing portion 31. Between the lower end of the hood 36 and the outer periphery of the ball grinder 28, a gap is provided over the entire periphery so that air can flow in from the outside. An intake port 37 is provided in the upper portion of the hood 36, and a deodorizer main body 39 is provided by a flexible tube 38.
It is connected to the. The deodorizer main body 39, like the deodorizer main body 10 of the first embodiment, has a deodorizing filter 40 and an electric fan 41 each having a laminated structure of honeycomb activated carbon and granular activated carbon.
Is provided inside, and a two-stage dust removal filter and a paper filter are attached in front of the deodorizing filter 40.

The odorous gas generated by the molding process of the spectacle lens 29 leaks from the gap of the sound deadening capsule 32 and is collected in the hood 36. Then, due to the suction force of the electric fan 41, the air coming in through the gap between the hood 36 and the ball grinder 28, together with the intake port 37 at the top of the hood.
Through the flexible tube 38 to the deodorizer body 39
Sent to. In the deodorizer body 39, after the dust is separated and removed by the dust filter and the paper filter, the odorous gas component is removed by the deodorizer filter 40, and is discharged indoors through the exhaust port 42 provided on the side surface of the deodorizer body 39. It

FIG. 4 shows an embodiment of a ball-slicing machine according to the present invention in which a conventional capsule-type ball-shaving machine is improved so that a deodorizing function is integrated. Unlike the conventional ball-slicing machine, the ball-shaving machine main body 43 is directly connected to the deodorizing machine main body 46 inside the silencing capsule 45 that covers the lens processing portion 44. That is, an intake port 47 is provided on the upper surface of the capsule 45, and one end of a flexible tube 48 extending from the deodorizer body 46 is detachably connected. Deodorizer body 4
6 is an electric fan, as in the case of the second embodiment of FIG.
It has a deodorizing filter, a two-stage dust removing filter, and a paper filter.

The capsule 45 does not hermetically close the lens processing portion 44, but allows air to flow into the interior through a gap in the peripheral portion. The gap in this case is very narrow as compared with the cases of the first and second embodiments. Therefore, if the electric fan used is a centrifugal type and its static pressure is high, the air volume is small. However, sufficient suction capacity can be obtained. Therefore, the odorous gas generated from the lens processing unit 44 is sent to the inside of the deodorizer main body 46 through the flexible tube 48 without leaking from the capsule to the outside, after removing dust and adsorbing the odorous gas component to the activated carbon. , Is exhausted indoors through the exhaust port 49.

In the embodiment shown in FIG. 4, the deodorizing machine main body and the ball slicing machine main body are separately provided, but they may be incorporated in a single unit. FIG. 5 schematically shows an embodiment of such a single unit ball shaving machine. As with the ball-slicing machine 43 in FIG. 4, the ball-slicing machine 50 has a lens processing portion 51 disposed on the upper portion thereof covered with a sound deadening capsule 52.
It is integrally mounted inside the housing 54 of the ball slide machine 50. Therefore, compared with the case of FIG. 4, it is possible to reduce the installation space of the ball slicing machine 50, and it is possible to sufficiently arrange the ball squeezing machine 50 even in a small spectacle store.

On the upper surface of the ball shaving machine inside the capsule 52, an intake port 55 is opened near the lens processing section 51, and the duct 5
6 is connected to the deodorizer 53. This allows the capsule 52 to be opened and closed more easily than in the embodiment of FIG. A plurality of the intake ports 55 can be provided along the periphery of the lens processing portion 51, or can be formed in an elongated slit shape.

The deodorizer 53 is provided with an electric fan, a deodorizing filter, a dust removing filter, etc., like the deodorizing unit main body 46 of the embodiment shown in FIG. In addition, on the side surface of the housing 54,
An exhaust port 57 is provided near the deodorizer 53. The odorous gas is guided to the deodorizer 53 from the intake port 55 via the duct 56 along with the air flowing in through the gap around the capsule 52, is dedusted and deodorized, and is then discharged from the exhaust port 57.

Further, the deodorizing apparatus of the present invention is ground or cut using a tool such as a grindstone, an end mill or a cutting tool in the process of finishing the outer diameter of a lens or the process of finishing a semi-finished blank into a lens in a spectacle lens manufacturing factory. The present invention can be applied to such a molding processing device in order to remove dust containing a malodor generated when performing. In the spectacle lens manufacturing factory, it is relatively easy to discharge the odor to the outside of the building using the exhaust duct, but it is possible to prevent the environment in the surrounding area from being harmful.

The present invention is not limited to the above-described embodiments, but can be implemented by making various changes and modifications to the above-described embodiments within the technical scope thereof. For example, as the first and second adsorbents of the deodorizing filter 18, instead of the honeycomb activated carbon, it is possible to use fibrous activated carbon which similarly has good workability / formability, small pressure loss and high adsorption ability. Also, instead of the granular activated carbon, it is possible to use powdery activated carbon which is inexpensive, disposable, and has a high adsorption ability. It is also possible to use impregnated activated carbon, which has added a chemical adsorption function to enhance the adsorption effect for specific odor components, or various conventional adsorbents such as zeolite, silica gel, activated alumina, in place of activated carbon or in combination with activated carbon. it can.

In the above embodiment, the adsorption method was adopted as the deodorizing method, and it was possible to obtain a sufficient deodorizing effect and at the same time make the entire apparatus compact and achieve low cost. Various well-known deodorizing methods such as methods, chemical cleaning methods and biodegradation methods can be used. For example, instead of a deodorizing filter made of activated carbon, a catalyst made by depositing platinum on the surface of alumina-based ceramics was installed, and odorous gas was heated to about 400 ° C to treat it. Although a slight irritating odor that could be absorbed was retained, a deodorizing effect substantially similar to that obtained by using the activated carbon filter was obtained.
Furthermore, when such a catalyst and activated carbon are combined, the life of the activated carbon filter is extended, so that maintenance of the deodorizer becomes easier.

[0058]

Since the present invention is constructed as described above, it has the following effects.

According to the deodorizing device for a ball-grinding machine of the first aspect, the odor can be removed without diffusing to the outside by a relatively simple and inexpensive structure, and the conventional ball-grinding machine can be used as it is. Therefore, the cost required for deodorization can be significantly reduced.

In addition to this, according to the deodorizing apparatus of the second aspect, the volume of the deodorizing filter can be reduced and the intake capacity of the deodorizing machine main body can be reduced while ensuring a sufficient deodorizing function. Since it is possible to reduce the cost, it can be installed easily even in a small-scale eyeglasses retail store because of its excellent space efficiency, and the cost can be reduced.

Further, according to the deodorizing device of claim 3,
The deodorizing function can be maintained for a long time without being impaired by dust, the life of the deodorizing filter can be extended and running costs can be reduced, and one of the dust removing filters can be installed after cleaning for cleaning. Even if you forget to do so, the other dust filter that is housed together with the deodorizing filter does not constantly separate and remove dust from odorous gas and does not clog the deodorizing filter. It is possible to prevent health and safety problems that may occur to people.

According to the deodorizing apparatus of the fourth aspect, the dust removing ability can be improved to enhance the deodorizing effect, and the number of times of cleaning and exchanging the dust removing filter can be greatly reduced by simply replacing the paper filter. Maintenance becomes easier, and the intake capacity of the deodorizer body can be easily adjusted without adding control means or changing specifications.
The cost of the device can be reduced.

According to the deodorizing device of claim 5, even a clerk of an eyeglass store who does not have specialized knowledge about the deodorizing device can easily handle the deodorizing device, and the maintenance is easy, and the activated carbon is comparatively inexpensive, and particularly the granular particles are granular. Since activated carbon is renewable, running costs can be reduced.

Further, according to the ball-slicing machine of the sixth aspect,
With a relatively simple configuration, the odor generated from the lens processing portion can be effectively removed without diffusing to the outside at a low price.

In addition to this, according to the ball-sliding machine of the seventh aspect, the volume of the deodorizing filter can be reduced and the suction capacity of the deodorizing portion can be reduced while ensuring a sufficient deodorizing function.
It is possible to reduce the size of the entire apparatus, realize a space-efficient and low-cost ball slicing machine.

According to the ball mill of claim 8, the deodorizing function is not impaired by the dust, the life of the deodorizing filter is extended, the running cost can be reduced, and at least one of the dust removing filters is housed together with the deodorizing filter. Therefore, the dust is not always separated and removed from the odorous gas and the deodorizing filter is not clogged, and the maintenance can be facilitated.

Further, according to the ball-slicing machine of the ninth aspect,
The dust removal capacity can be improved and the deodorizing effect can be enhanced, and the number of times the dust filter is washed and replaced can be greatly reduced by disposing of the paper filter, which makes maintenance easier and improves the intake capacity of the deodorizing part. Since the adjustment can be easily performed, it is possible to suppress an increase in the manufacturing cost due to the addition of the control means or the change of the specifications.

According to the ball slicing machine of the tenth aspect, the maintenance is easy, and even a clerk of an eyeglass store who does not have specialized knowledge about the deodorizing device can easily handle it, and the activated carbon is relatively inexpensive, and the granular activated carbon is particularly preferable. Since it is renewable, running costs can be reduced.
