The processing tank 28 is formed in an overflow tank as shown in FIG. 5A, and the overflowed processing liquid is supplied to the pump 29a and the filter 29b through the pipe 29 and filtered. It is formed so as to circulate again in the tank.
[0006]
When performing wet processing using such a conventional wet processing apparatus, as shown in FIG. 5A, first, a plurality of objects to be processed 1 are accommodated in the transport jig 22 and placed on the rail body 24. At the same time, the conveying jig 22 is pushed by the conveying mechanism 21 and slid and conveyed to the upper portion of the processing tank 28. Then, when the transport jig 22 moves to the upper part of the processing tank 28, as shown in FIG. 5B, the transport mechanism 21 is stopped, and at the same time, the elevating means 26 is driven to lower the hanger 26a to lower the rail body 24. And the conveying jig 22 are immersed in the treatment tank 28. As a result, the transport jig 22 performs wet processing on the plurality of workpieces 1 immersed in the processing liquid stored in the processing tank 28 and stored therein. At this time, in the processing tank 28, the pump 29a is driven to supply overflow processing liquid to the pump 29a and the filter 29b through the pipe 29, and then filtered to circulate again in the tank. Thereafter, when the wet process is completed, as shown in FIG. 5A, the hanger 26 a of the elevating means 26 is raised again, and the transport jig 22 is transported to the next processing step by the transport mechanism 21.
[0007]
As described above, the conventional wet processing apparatus accommodates a plurality of objects to be processed 1 in the transport jig 22 and places them on the rail body 24 in the main body 20, so that the transport mechanism 21 in the main body 20 has a processing tank 28. In addition, the wet processing is smoothly performed by the elevating means 26 so that it can be transported to the next process.
[0008]
[Problems to be solved by the invention]
However, in the conventional wet processing apparatus, the hanger 26a and the rail body 24 do not interfere with each other because the hanger 26a and the rail body 24 are immersed in the processing tank 28 together with the transport jig 26 as shown in FIG. Thus, it is necessary to provide a large volume in the processing tank 28, and a large amount of processing liquid is required, and the efficiency of circulating and filtering by the filter 29b and the pump 29a is deteriorated. Further, in the conventional wet processing apparatus, as described above, parts such as the hanger 26a and the rail body 24 that are not directly related to the wet processing are directly immersed in the processing bath 28. There is also a problem that the degree cannot be raised.
Further, in the conventional wet processing apparatus, as described above, the volume of the processing tank 28 is increased, and at the same time, it is necessary to secure an arrangement space for the elevating means 26 for raising and lowering the rail body 24 in the vicinity of the processing tank 28. The entire apparatus (main body 20) is enlarged. For example, when various treatment liquids are used by connecting a plurality of treatment tanks 28, the lifting / lowering means 26 is required for each treatment tank 28, and the entire apparatus is greatly enlarged. There was a drawback of doing.
The present invention solves such problems, and provides a wet processing apparatus that reduces the amount of processing liquid used by reducing the size of the entire processing tank and reducing the amount of processing liquid, thereby improving the circulation efficiency. For the purpose.

FIG. 1 is a block diagram showing an embodiment of a wet processing apparatus according to the present invention. Moreover, FIG. 2 is a figure which shows the other Example of the conveyance jig shown in FIG. 3 is a diagram showing the operation of the wet processing apparatus shown in FIG. 1. FIG. 3 (a) shows a state before the workpiece 1 is immersed in the processing tank 18, and FIG. The state to which the to-be-processed object 1 was immersed in the processing tank 18 is each shown.
[0012]
As shown in FIG. 1, an embodiment of the wet processing apparatus according to the present invention is an apparatus for performing wet processing on an object 1 such as a lens or a metal part as in the prior art shown in FIG. At least one or more transfer jigs 12 that hold the workpiece 1 in the air, a rail body 14 that engages with both lower ends of the transfer jig 12 and guides and conveys the processed objects 1 in a predetermined direction, and are disposed below the rail body 14. And a treatment tank 18 in which a treatment liquid for immersing the object to be treated 1 and storing a wet treatment is stored.
[0013]
Here, unlike the prior art shown in FIG. 4, the processing tank 18 is held by a lifting / lowering means 16 below the rail body 14, and transports the transport jig 12 by the rail body 14 and stands by. It raises from the lower part hold | maintained to the to-be-processed object 1 in the air, and it forms so that the to-be-processed object 1 may be immersed in a process liquid and wet-processed. In addition, the conveying jig 12 includes a concave hook 12a made of a metal mesh that accommodates a plurality of objects 1 to be processed, a frame 12b that extends from the top to both sides in order to suspend the hook 12a, and the frame 12b. A lower end portion 12c that extends to the lower portion of the rail body 14 and engages with the rail body 14, and engages the lower end portion 12c with the rail body 14 so that the flange portion 12a is suspended. And is wet-processed. Here, although the conveyance jig 12 demonstrated the Example which provided and suspended the collar part 12a which accommodates the to-be-processed object 1, it is not limited to this, For example, hold | maintains to-be-processed object one by one. Multiple suspensions are possible. Another embodiment of the conveying jig 13 that holds and suspends such objects to be processed one by one holds at least one object to be processed 1 as shown in FIG. Holding part 13a to be held), a frame part 13b extending from the upper part to which the holding part 13a is suspended to both sides, and a lower part of the frame part 13b to be engaged with the rail body 14 (see FIG. 1) And lowering the processing tank 18 (see FIG. 1) from below to wet-treat the rail body 14 by engaging the lower end 13c with the rail body 14 and suspending a plurality of holding portions 13a. . In another embodiment of such a transport jig, the same effect as the transport jig shown in FIG. 1 can be obtained due to the structure in which a plurality of objects to be processed 1 are suspended from the frame portion 13b.
[0014]
Referring again to FIG. 1, the rail body 14 uses transport means (a plurality of rollers arranged in FIG. 1) such as a rotary roller, a chain, and a belt that engage with the lower end portion 13 c of the transport jig 13. It is configured so that it can be transported horizontally to the next processing step. The rail body 14 has a substantially cylindrical roller projecting from both sides at the bottom of the lower end portion 12c, and the both ends are held so that the diameter of the roller extends outward and the lower end portion 12c is not removed. The rail body 14 is formed so that the roller is rotated by a drive source such as a motor (not shown). Therefore, since the present embodiment has a structure in which the treatment tank 18 is lifted from below the conveyance jig 12 conveyed by the rail body 14 and wet treatment is performed, the small treatment tank 18 in which only the flange portion 12a of the conveyance jig 12 is immersed. Can be formed.
[0015]
Further, the processing tank 18, the rail body 14, and the lifting means 16 are provided with a main body 10 that integrally surrounds and surrounds the periphery as in the prior art shown in FIG. Maintains a clean condition. The elevating means 16 includes a hanger 16a for holding the processing tank 18, and has a structure for elevating and lowering the hanger 16a by a vertical movement mechanism of a thrust by a motor or a cylinder. Here, since the raising / lowering means 16 does not need to provide an arrangement space for raising and lowering the rail part in the vicinity of the treatment tank as in the prior art, it can be installed in the lower part of the rail part 14, so it is arranged even in a narrow installation space in the main body 10. And the entire apparatus can be miniaturized. Then, as shown in FIG. 3A, the processing tank 18 is formed in an overflow tank, and this overflowed processing liquid is supplied to the pump 19a and the filter 19b via the pipe 19 and filtered to return to the tank. It is formed to circulate inside. At this time, unlike the prior art, when the processing tank 18 is moved up and down by the lifting and lowering means 16, a flexible pipe 19 c having flexibility is interposed in the pipe 19 connecting the pump 19 a and the filter 19 b to the pipe 19. Arranged so as not to apply a load.
[0016]
By the way, in the present embodiment, it is possible to arrange a plurality of treatment tanks 18 in the main body 10 shown in FIG. 1. For example, a plurality of main bodies 10 in which the treatment tanks 18 are divided into units are provided. A plurality of main bodies 10 including the processing tanks 18 for each tank may be connected in series according to the purpose. Thus, in this embodiment, by connecting a plurality of main bodies having different processing purposes in series, various configurations according to processing requirements can be easily realized, and it is possible to cope with diversified processing steps. Here, when the object to be processed is a plastic lens, for example, it has a plastic lens manufacturing process such as an alkali cleaning process, a rinsing process, a drying process, a coating process, a thermosetting process, and the processing liquid of this embodiment. Can be changed to correspond to an alkali washing step (alkaline solvent), a rinsing treatment step (cisi, pure water), and a coating treatment step (coating solution), respectively.
[0017]
And when performing wet processing using one embodiment of such a wet processing device by the present invention, first, as shown in Drawing 3 (a), first, to-be-processed object 1 is put on flange 12a of conveyance jig 12. A plurality of containers are accommodated and placed on the rail body 14, and the rollers of the rail body 14 are rotated by a drive source (not shown) so that the transport jig 12 is slid and transported to the upper portion of the processing tank 18. When the transport jig 12 moves to the upper part of the processing tank 18, as shown in FIG. 3 (b), the rotation of the rail body 14 is stopped and the transport of the lower end portion 12c is stopped, and at the same time, the elevating means 16 is driven. The processing tank 18 held on the hanger 16 a is raised toward the flange 12 a suspended from the frame 12 b of the transport jig 12. At this time, the flexible pipe 19c is interposed between the pump 19a and the filter 19b and the processing tank 18, so that the flexible pipe 19c is connected to the processing tank 18 as shown in FIG. It is possible to prevent the load from being extended as it rises. Thereby, the conveyance jig 12 immerses only the collar part 12a in the processing liquid stored in the processing tank 18, and wet-processes the plurality of objects 1 to be stored therein. At this time, in the treatment tank 18, the pump 19 a is driven and the overflowing treatment liquid is supplied to the pump 19 a and the filter 19 b through the pipe 19 and filtered to circulate again in the tank. Thereafter, when the wet process is finished, as shown in FIG. 3A, the hanger 16a of the elevating means 16 is lowered again to drive the rail body 14, and the transport jig 12 is moved to the next processing step (for example, drying). (Process).
[0018]
Thus, according to one embodiment of the wet processing apparatus according to the present invention, as shown in FIG. 3B, only the flange portion 12a of the transport jig 12 is immersed in the processing liquid in the processing tank 18. The volume of the treatment tank 18 can be reduced to match the flange 12a, the amount of treatment liquid used can be reduced, and the efficiency of circulating and filtering by the filter 19b and the pump 19a can be improved at the same time. Therefore, this embodiment can be expected to reduce the power consumption of the apparatus and reduce the running cost, and contribute to the reduction of the environmental load by reducing the drainage after the wet treatment.
[0019]
Further, according to one embodiment of the wet processing apparatus according to the present invention, as described above, since the wet processing is performed by immersing only the flange 12a of the transport jig 12 in the processing liquid in the processing tank 18, the flange 12a. In addition, contamination of the processing liquid by parts other than the workpiece 1 can be prevented, and the cleanliness in the processing tank 18 can be increased.
[0020]
Furthermore, according to one embodiment of the wet processing apparatus according to the present invention, a plurality of processing tanks 18 are reduced in size and the lifting means 16 is disposed below the rail body 14 to minimize the installation space in the main body 10. Even when the processing tanks 18 are arranged and various processing liquids are used, the entire apparatus (main body 10) can be downsized. Therefore, in the present embodiment, there is a clear difference in the device dimensions compared to the prior art device shown in FIG. 3, and for example, in the case of a plastic lens manufacturing device, the device length and depth are each halved. Therefore, it can also contribute to manufacturing cost reduction.
[0021]
Although the embodiment of the wet processing apparatus according to the present invention has been described in detail above, the present invention is not limited to the above-described embodiment, and can be changed without departing from the gist thereof.
For example, the embodiment in which a plurality of treatment tanks are connected and wet-treated has been described. However, the present invention is not limited to this, and only a single treatment tank is sealed in the main body to wet-treat the workpiece. Is also possible.
[0022]
【The invention's effect】
As described above, according to the wet processing apparatus of the present invention, since the structure is such that only the transport jig holding a plurality of objects to be processed in the air is immersed in the processing liquid in the processing tank, the volume of the processing tank is made small according to the transport jig. And the amount of processing solution used can be reduced.
Further, according to the wet processing apparatus of the present invention, since the wet processing is performed by immersing only the transport jig in the processing liquid in the processing tank as described above, the processing liquid by parts other than the transport jig and the object to be processed is used. Contamination can be prevented and the cleanliness in the treatment tank can be increased.
Furthermore, according to the wet processing apparatus of the present invention, the processing tank can be downsized and the lifting means can be arranged at the lower part of the rail portion to minimize the installation space in the apparatus. Even if this processing solution is used, the size of the entire apparatus can be reduced.
