Description

  The present invention relates to a grinding water treatment apparatus that separates and processes grinding waste from used grinding water used when a spectacle lens is ground by a lens grinding processing apparatus.

Conventionally, when an eyeglass lens such as a plastic lens (for example, a high refractive index plastic lens, a CR lens, etc.) is ground by a lens grinding apparatus, an odor containing a sulfur component (for example, hydrogen sulfide H ₂ S, bad odor) Since harmful substances are generated in the processing chamber of the lens grinding apparatus, it is well known that this odor is sucked from the grinding water tank and deodorized by a deodorizing apparatus using activated carbon or a photocatalyst. (For example, see Patent Documents 1 to 3).

Further, for example, as shown in claim 1, paragraphs 0002, 0012 to 0013, 0020 to 0027 and FIG. 1 of Patent Document 4, the grinding water (grinding fluid) rises to about 40 ° C. by the heat of the grinding water pump, etc. Odor is more likely to occur, so cooling means (cooling device) for cooling the grinding water (grinding fluid) in the grinding water tank (storage tank) that stores the grinding water (grinding fluid) is provided and cooled. The grinding water in the ground grinding water tank (storage tank) is sent to the grinding part (processing room of the lens grinding machine) by the circulation pump (grinding water piping), sprayed to the lens by the spraying means, and cooled grinding water ( 2. Description of the Related Art A grinding water treatment apparatus that can prevent the generation of odor caused by normal lens grinding by dispersing a grinding fluid) onto a lens is known.
JP 2001-37865 A JP 2006-326776 A JP 2006-326822 A Japanese Utility Model Publication No. 6-61445

  However, when the cooling device as shown in the above-mentioned Japanese Utility Model Publication No. 6-61445 is arranged in a grinding water tank (a storage tank for storing grinding water or grinding fluid), the cooling device is in direct contact with the grinding water. Therefore, there is a tendency that the cooling capacity is limited, and the temperature of the grinding water rises while the grinding water circulates in the circulation pump, which may cause odor.

  In particular, the grinding water that passes through the grinding water pipe close to the processing chamber is heated by the drive unit that drives the grinding wheel, and odor is likely to be generated.

  Conventionally, grinding grinding is performed while using grinding water when grinding, but when grinding is repeated, the water temperature of the grinding water is affected by the drive member that drives the grinding stone. Grinding heat that would be overheated by this occurs.

  For this reason, components that cause malodors (for example, hydrogen sulfide molecules H2S) are also activated by heating, increasing the amount of generation and increasing malodors.

  In addition, since the temperature of the grinding water rises, the function of coolant (removal of grinding heat, removal of heat) for lens grinding is sufficiently slowed down.

  Therefore, the present invention suppresses the temperature rise of the grinding water and suppresses the generation of malodorous components (for example, hydrogen sulfide molecule H2S), and continues the function of removing grinding heat and removing heat accompanying grinding. An object of the present invention is to provide a grinding water treatment apparatus for a lens grinding apparatus that can be used.

  In order to solve the above problems, the present invention is characterized by matters described in the claims.

  When the cooling member for cooling the grinding water is arranged in one or both of the grinding water tank and the grinding water pipe so as not to be in direct contact with the grinding water, it is easy to obtain a desired cooling capacity and reliably suppress the temperature rise of the grinding water. In addition (or without), if a cooling member is also provided in the odor pipe, the generation of components that cause bad odor (for example, hydrogen sulfide molecule H2S) is effectively suppressed, and the heat of grinding accompanying the grinding process is reduced. Removal and heat removal can be maintained.

  The grinding water tank 30 is a container that is disposed below the shelf plate 6d that divides the inside of the main body case 6 and that opens upward.

  In the grinding water tank 30, a housing-like sub tank 31 having a shape retaining property is arranged.

  The sub tank 31 has a hollow cylindrical shape, and a large number of filter holes 32 are formed in the peripheral wall 31a, and a connection port 33 is formed in the upper wall 31b. A drain hose 111 connected to the bottom wall 11 a of the drain receiver 11 is connected to the connection port 33. The plurality of cooling members 100 are also arranged on the surface of the drainage hose 111 so as not to come into contact with the used grinding water, but the illustration is omitted because the figure becomes complicated.

  Further, the large number of filter holes 32 have a sufficiently small diameter so that only the water of the used grinding water introduced through the drainage hose 111 passes therethrough.

  Furthermore, a discharge port 30a is formed in the grinding water tank 30 and communicates with the pump 35 via a discharge hose 34 connected to the discharge port 30a.

  The pump 35 is fixed in the main body case 6 via a bracket B, and a suction port 35a is formed on the side surface, and a discharge port 35b is formed on the upper surface. A discharge hose 34 is connected to the suction port 35a, and a hose 36 connected to the water supply hose 4 of the lens grinding apparatus 2 is connected to the discharge port 35b. A plurality of cooling members 100 are also arranged on the surface of the hose 36 so as not to come into contact with the grinding water, but one is arranged because the figure becomes complicated.

  Next, the operation of the aforementioned deodorizing system will be described.

  In such a configuration, when the lens grinding apparatus 2 is powered on, an arithmetic control circuit (not shown) of the lens grinding apparatus 2 first operates the drive motor 13. The rotation of the drive motor 13 is transmitted to the rotating shaft 116 through the coupling 131 and the coupling 118, and the flange 117 and the dewatering tank 12 are rotated integrally with the rotating shaft 116.

  Next, the arithmetic and control circuit of the lens grinding apparatus 2 operates the pump 35 to cause the pump 35 to suck the grinding water in the grinding water tank 30. The grinding water sucked into the pump 35 is supplied to a nozzle (not shown) in the processing chamber via the hose 36 and the water supply hose 4 and is sprayed from the nozzle toward a grinding wheel (not shown).

    When the arithmetic control circuit of the lens grinding apparatus 2 starts spraying of grinding water from the nozzle toward the grinding wheel (not shown), the grinding process of the spectacle lens by the grinding wheel is performed on the lens shape information (θi, ρi). Start based on.

  Grinding debris generated during the grinding is washed away by the grinding water and flows down to the bottom of a processing chamber (not shown). The grinding water (used grinding water) containing the ground grinding scraps flows from the drain hose 3 to the branch pipe 50 as waste liquid. Then, the water is discharged to the grinding water treatment device 5.

  Here, for example, when a plastic lens is ground by the lens grinding apparatus 2, an odor containing a sulfur component or the like is generated in a processing chamber (not shown). The odor-containing air is discharged from the drainage hose 3 through the branch pipe 50 into the grinding water treatment device 5 together with the used grinding water.

  As shown in (a) of FIG. 4, used grinding water and air containing odor are discharged from the drain hose 3. At this time, the air spirally turns along the inner surface of the separation pipe 51 of the branch pipe 50, and the used grinding water flows down substantially vertically by its own weight.

  As shown in (b) of FIG. 4, the swirled air flows into the exhaust pipe 52 extending from the separation pipe 51 and flows into the deodorizing device 20.

  Further, the used grinding water that has flowed vertically is drained into the inner cylinder 122 of the rotating dewatering tank 12. The used grinding water including the grinding waste drained into the inner cylinder 122 passes through the slit 124a due to the centrifugal force accompanying the rotation of the inner cylinder 122, and the space Sa (between the inner cylinder 122 and the cylindrical filter 14a ( 6 and FIG. 8).

  The used grinding water including the grinding waste flowing into the space Sa is transmitted through the cylindrical filter 14a and the mesh tube 14 and the space Sb between the mesh tube 14 and the tube filter 15a (FIG. 6, FIG. 8)).

  At this time, most of the grinding waste contained in the used grinding water is captured by the cylindrical filter 14a located inside. However, it is also conceivable that a small amount of grinding waste passes through the cylindrical filter 14a together with the used grinding water and flows into the space Sb.

  The used grinding water that has flowed into the space Sb passes through the tubular filter 15 a and the mesh tube 15 and flows into the drain receiver 11. At this time, even if the used grinding water that has flowed into the space Sb contains grinding scraps, the grinding scraps are captured by the cylindrical filter 15a located outside.

  The used grinding water from which most of the grinding debris has been removed in this manner is blown in the radial direction by centrifugal force and collides with the inner surface of the drain receiver 11, and then flows downward and is ground via the drain hose 111. It flows into the tank 30.

  In addition, an adsorbing substance that chemically or physically adsorbs sulfur-based compounds such as hydrogen sulfide molecules H2S is disposed in the cylindrical filters 14a and 15a and / or the net-like cylinders 14 and 15 of the dewatering tank 12 of the grinding water treatment apparatus 5. . For example, Ag + or the like is applied to the cylindrical filters 14a and 15a and the net-like cylinders 14 and 15 as an adsorbent that chemically or physically adsorbs with a sulfur-based compound such as hydrogen sulfide molecule H2S. Thereby, it is possible to deodorize and deodorize the malodor generated from the sulfur-based compound in the grinding water.

  Here, the drain hose 111 is connected to a sub tank 31 arranged in the grinding water tank 30. Thereby, the used grinding water from which the grinding waste has been removed is first introduced into the sub tank 31.

  The used grinding water introduced into the sub tank 31 passes through a large number of filter holes 32 formed in the peripheral wall 31 a and flows out into the grinding water tank 30.

  Here, the filtration hole 32 has a sufficiently small diameter and does not allow bubbles generated in the used grinding water to permeate, and the bubbles are confined in the sub tank 31. In addition, since the sub tank 31 has a shape having a shape retaining property, the bubbles can be confined without being deformed by the momentum of the used grinding water flow.

  Thereby, the foam generated from the used grinding water can be reliably separated (filtered) from the grinding water.

  Further, the grinding water (filtered grinding water) extracted from the sub tank 31 and flowing into the grinding water tank 30 is convected and stirred in the grinding water tank 30 by the momentum flowing into the grinding water tank 30. It becomes. As a result, the fine bubbles that have passed through the filtration hole 32 of the sub tank 31 also disappear, and the bubbles can be removed more sufficiently.

  The filtered ground water from which bubbles have been removed in this manner is sucked into the pump 35, and the sucked filtered ground water is discharged from the pump 35 to the hose 36, and is supplied from the hose 36 through the water supply hose 4. Then, water is supplied to the processing chamber of the lens grinding apparatus 2.

  On the other hand, the air containing the odor that has flowed into the exhaust pipe 52 flows into the deodorizing chamber 22 of the deodorizing apparatus 20 through the duct 52a continuous from the exhaust pipe 52.

  Here, since the first filter member 221 is provided on the side surface of the deodorizing chamber 22, the air containing odor first passes through the first filter member 221 and then fills the inside of the first filter member 221. The second filter member 222 is transmitted.

  At this time, the odor is adsorbed by the first filter member 221 and the second filter member 222 and deodorized. The deodorized air passes through the blower chamber 24 from the communication pipe 25 and is exhausted to the outside air from an exhaust port (not shown).

  In this deodorizing apparatus 20, since the first and second filter members 221 and 222 are deodorized, the odor generated by the lens grinding process can be almost completely removed.

  Further, another exhaust pipe is provided in the middle of the exhaust pipe 52, the air exhausted into the main body case 6 is sucked through the exhaust pipe, and the air is deodorized without being exhausted to the outside air by being led to the deodorizing device 20 again. Can be circulated to make it completely odorless.

  Further, when discarding the grinding scraps captured by the cylindrical filters 14a and 15a of the dewatering tank 12, after removing the lid 9 from the opening 8a of the upper plate 6c, the fixing screw 128 is removed from the flange 117 of the rotating shaft 116. It removes and the dehydration tank 12 is extracted from the inside of the drain receptacle 11.

  By removing a screw (not shown), the inner cylinder 122 of the dehydrating tank 12 is removed from the rotating plate 121. Then, the reticular cylinders (filter support frames) 14 and 15 can be removed from the rotating plate 121, and the cylindrical filters 14a and 15a can be taken out of the reticular cylinders 14 and 15 together with the grinding waste and discarded.

  As mentioned above, although the deodorizing system by one best embodiment of this invention was shown in figure and explained in full detail, a specific structure is not restricted to the above-mentioned embodiment. Design changes and the like within the scope not departing from the gist of the present invention are included in the scope of the present invention.

  For example, in the above-described embodiment, the filtered ground water discharged from the pump 35 is directly supplied to the lens grinding device 2 via the water supply hose 4. The lens grinding apparatus 2 may be supplied with water.

  In this way, by introducing the filtered grinding water from which bubbles have been removed by the sub-tank 31 to the centrifuge, the residual bubbles remaining in the filtered grinding water can be further reliably separated and removed. .

  Further, as shown in FIG. 9, the sub tank 311 and the foam suction pump 80 are connected via a first foam removal hose 81 and also connected to the foam suction pump 80 and a lens grinding apparatus (not shown here). The drain hose 3 ′ may be connected via the second defoaming hose 82.

  It is preferable to arrange the plurality of cooling members 100 on the outer surface of the second defoaming hose 82 so as not to directly contact the grinding water.

  In this case, the bubbles trapped and separated in the sub tank 311 are sucked into the foam suction pump 80 by the first foam removal hose 81. This foam suction pump 80 is provided on the top plate 30b of the grinding water tank 30 ′, and sucks foam using the drive of a drive motor 13 that rotates the dewatering tank 12.

  Here, the upper opening of the grinding water tank 30 'is closed by the top plate 30b. The rotating shaft 84 of the foam suction pump 80 is connected to the rotating shaft 116 ′ protruding from the drain receiver 11 ′ via a belt 83.

  On the other hand, the foam sucked by the foam suction pump 80 is again introduced into the dehydration apparatus 20 via the second foam removal hose 82.

  As a result, even if it floats on water such as grinding dust contained in the foam, especially grinding waste generated from water-repellent spectacle lenses, it can be removed sufficiently and generated from used grinding water. It is possible to completely remove the bubbles.

  Further, as shown in FIG. 10, the sub tank 311 may be supported by a plurality of legs 313 protruding from the peripheral edge of the bottom wall 311a while a large number of filtration holes 312 are formed in the bottom wall 311a.

  In this case, the drain hose 111 ′ connected to the drain receiver 11 ′ is connected to a connection port (not shown) formed in the upper wall 311 b of the sub tank 311, and used grinding water is supplied to the sub tank 311 through the drain hose 111 ′. It comes to flow in. A plurality of cooling members 100 are also arranged on the outer surface of the drain hose 111 ′ so as not to contact the used grinding water.

  The filtered ground water from which bubbles have been removed by the sub tank 311 flows out from a large number of filtration holes 312 formed in the bottom wall 311a of the sub tank 311 and enters the ground water tank 30 ′ from between the plurality of legs 313. It has come to flow out.

  Here, since the filtration hole 312 is formed in the bottom wall 311a of the sub tank 311, bubbles floating upward in the sub tank 311 are less likely to flow out of the sub tank 311, and the bubbles generated from the used grinding water are further sufficiently removed. be able to.

  FIG. 18 shows an example of an automatic operation sequence of the deodorization system.

  As shown in FIG. 18, when the driving power cord 406 of the lens grinding apparatus 420 is input to the power source and driven, the power driving signal is input to the driving power source of the grinding water treatment device 429 through the cord and supplied to the water supply pump motor 423. While the drive power is turned on, the water supply pump motor 423, the rotation motor 425 for the dewatering tank 424 of the dehydrating device, the motor 427 for the deodorizing fan 426 of the deodorizing device, and other stirring devices (propellers) for stirring the grinding water tank ) Motors such as motors and bubble sucking motors are turned on. Thereafter, even after the treatment process of the grinding water treatment device 429 is completed and the feed water pump motor 423 is stopped, the motor for the rotation motor 425 of the dehydration tank 424 of the dehydration device and the deodorization fan 426 of the deodorization device after a predetermined time has elapsed. 427, the timer is set so that various motors such as the motor of the stirring device that stirs the inside of the grinding water tank, the bubble sucking motor, and the like, so that the arbitrary operation operation after the water supply pump motor 423 stops can be performed. It is configured.

  Further, the power supply cord 421 from the lens grinding apparatus 420 and the drive power cord 422 of the grinding water treatment device 429 are connected, and the water supply pump motor 423, the rotation motor 425 of the dewatering tank 424 of the dewatering device, and the motor of the deodorizing fan 426. 427, supply power to all other drive motors, and triggered by an input signal input to the drive power supply of the lens grinding device processing unit 420 as a trigger, the feed water pump motor 423, the rotation motor 425 of the dewatering tank 424 of the dewatering device, the deodorizing fan In a state in which the motor 427 of 426 and all other driving motors are driven, the lens grinding device processing unit 420 counts the number of times of driving power source when the spectacle lens is ground, and measures the number of the ground lenses. Therefore, the number of lenses is dewatered by the grinding water treatment device 429. It can be regarded as a number of lenses to be.

  The driving power signal of the lens grinding device processing section 420 is input to the driving power of the grinding water treatment device 429 and is linked to the driving of the grinding water treatment device 429. Therefore, the number of lenses subjected to grinding is the dehydration tank 424 of the dehydration device. This corresponds to the number of lenses to be dehydrated.

  Therefore, the number of lenses subjected to grinding is regarded as the number of lenses dehydrated by the grinding water treatment device 429, that is, the number of lenses filtered by the dewatering tank 424, and is compared with a predetermined filtration allowable number in the dewatering tank. When the number of lenses that have been removed, that is, the number of lenses that have been dehydrated by the dehydrating device, exceeds the allowable number of filtrations, a warning or warning is displayed and displayed to the operator. As a result, it is possible to prevent the dehydration tank from being clogged with the dehydration tank being clogged by exceeding the permissible number of filtrations, and preventing the dehydration process from being performed.

  The number of lenses filtered by the dehydration tank 424 may be counted by the number of rotations of the dehydration tank, and the number of lenses may be calculated therefrom.

  Further, the number of filtrations in the dewatering tank is counted by the arithmetic and control unit provided in the grinding water treatment device 429, compared with the permissible filtration number, and when the permissible filtration number is exceeded, displayed to the operator in characters or figures, You may make it warn.

  FIG. 19 shows the panel unit 430 of the grinding water treatment device 429. The panel unit 430 is provided with a power switch 431, a power / sensor activation lamp 434, a counter activation lamp 435, and a reset switch 436. Normally, when the power switch 431 is input, the power / sensor activation lamp 434 is lit red by the red LED, and the counter activation lamp 435 is also lit green by the green LED to indicate to the operator that the apparatus is in the activated state. It is like that. In the event of an emergency, the reset switch 436 is pressed.

  FIG. 20 shows a state where the drive power of the grinding water treatment apparatus is OFF. The power / sensor activation lamp 434 is turned off.

  In FIG. 21, the driving power of the grinding water treatment device 429 is ON, and the power / sensor activation lamp 434 is lit red with the red LED emitting light.

  FIG. 22 shows that the red LED of the power source / sensor activation lamp 434 emits light in a short cycle, the red lighting repeatedly blinks, and the dewatering device of the grinding water treatment device 429 is operating. Although not shown, a sensor is installed in the dehydrating tank 424 of the dehydrating apparatus, and it is checked whether or not the dehydrating tank 424 is operating normally.

  FIG. 23 shows a state in which the operation of counting the number of lenses from which the grinding water is dehydrated by the dewatering tank 424 of the grinding water treatment apparatus 429 is turned off, and the number of ground lenses, that is, dewatering is performed. This indicates that the number of lenses (C) is less than the lower limit (X) of the allowable number of filtrations (the light extinction / processed sheet count value (C) is less than the set value). The permissible filtration number (X) can be set arbitrarily. In this case, it indicates that C <X.

  In FIG. 24, the counter activation lamp 435 is lit in green, the green LED is repeatedly flashing slowly (flashing in a long cycle), and the number of lenses whose grinding water is dehydrated by the dewatering tank 424 of the grinding water treatment device 429 is counted. This indicates that the operation is ON, and the number of ground lenses, that is, the number of lenses to be dehydrated (C) is larger than the lower limit (X) of the allowable number of filtrations, and the upper limit (Y) of the allowable number of filtrations. (The processed sheet count value (C) exceeds the limit value (X)).

  Note that the lower limit (X) and upper limit (Y) of the permissible filtration number can be arbitrarily set. In this case, X <C <Y. For example, if X = 70 and Y = 90, then 70 <C <90.

  In the state of FIG. 25, the counter start lamp 435 is lit in green, and the green LED repeatedly flashes quickly (flashes in a short cycle), and is greater than the upper limit (Y) of the allowable number of filtrations (the processed sheet count value (C ) Indicates that the limit value (Y) has been exceeded, and since the filtration allowable range of the dewatering tank has been exceeded, a buzzer sounds and warns the operator.

  In addition, a liquid crystal display unit is provided on the panel unit 430 of the grinding water treatment device 429, and the startup state of the grinding water treatment device 429, the display of the number of filtrations (display by numbers, figures, etc.), and the display of the allowable number of filtrations (for example, “Current” 15 / permissible number 1000 ”or a figure such as a cursor) or a warning display when the allowable number of filtrations is exceeded may be displayed.

24 and 25, when the counter activation lamp 435 blinks slowly, lighting / extinguishing is repeated at 0.2 seconds / 1.3 seconds, and when the counter activation lamp 435 blinks quickly, lighting / extinction is 0. The number of lenses (processed sheet count value (C)) to be dehydrated repeatedly at 2 seconds / 0.3 seconds is effective even when the power is turned off, and the storage unit (not shown) of the grinding water treatment device 429 The number of lenses to be dehydrated, that is, the processed number count value (C) can also be set by the number of activations (P) of the water supply pump of the lens grinding apparatus, and the relational expression at that time is , C = C + P / 2.

  In the state of FIG. 26, the reset switch 436 resets the number of lenses to be dehydrated, for example, clears the processed number count value (C) and cancels the counter blinking (see FIG. 27).

  However, the reset is effective only when the lid of the dewatering tank 424 of the grinding water treatment device 429 is opened.

  The count value can be reset to zero by turning on the reset switch 436 when replacing the filter.

  The counter value will not return to zero unless reset. Even when the power is turned off, the data is stored in the storage unit of the grinding water treatment device 429.

  Further, depending on the type of spectacle lens, for example, high refractive index plastic lens, CR lens, etc., particles of grinding scraps are different, and the dewatering tank 424 of the grinding water treatment device 429 is clogged, and the grinding water is dehydrated. I can't.

  For example, in a high refractive index plastic lens, grinding dust particles are elongated and do not aggregate to form clusters even if they settle in grinding water.

  On the other hand, in the CR lens, if the grinding dust particles are fine and settle in the grinding water, they aggregate to form a cluster and clog the dehydrated layer.

  Therefore, the lens type is input to the grinding device processing unit 420 in advance, the lens type information is input to the dewatering device of the grinding water treatment device 429, and the rotation speed of the dewatering layer 424 can be varied according to the lens type. It is preferable to control.

  When the spectacle lens is a high refractive index plastic lens, the dehydration process is performed while rotating at a low speed, and when the spectacle lens is a CR lens, the high speed rotation is continued and the dehydration process is performed. As for other types of spectacle lenses, it is preferable to variably control the rotation speed of the dehydration layer according to the type.

  Accordingly, the number of rotations of the dewatering tank 424 and the method of controlling the rotation (variable so that the rotation is initially performed at a low speed and the rotation at a high speed is finally performed according to the characteristics of the grinding dust particles depending on the lens material and composition of the spectacle lens. By changing the control mode, it becomes possible to prevent clogging of the dehydration tank and perform dehydration processing according to the lens material of the spectacle lens.
