浄時間が長くなるという問題点を有する。[Problems to be Solved by the Invention] By the way, in order to color a plastic lens, which is one of the optical members, it is necessary to use an 80 to 80% disperse dye containing a disperse dye with a dye concentration of about 0.1 to 1.0% by weight.
A commonly used method is to immerse a plastic lens in a dye solution at 90° C. for coloring. When the plastic lens is removed from the dyeing solution after coloring, the disperse dye in the dyeing solution adheres to the surface of the plastic lens. Particularly when half dyeing is performed, the degree of adhesion of the disperse dye becomes stronger. For example, when cleaning plastic lenses with disperse dyes attached using the ultrasonic cleaning method and device disclosed in JP-A-59-166282, the cleaning power of the ultrasonic waves is insufficient and the particles are dispersed. The problem is that the dye cannot be completely removed from the plastic lens. Also, JP-A-58-1896
The brush cleaning method and device disclosed in Publication No. 09 are as follows:
Although it has enough cleaning power to remove disperse dyes from plastic lenses, it has the problem that both sides cannot be cleaned at the same time, which increases the cleaning time.

It is an object of the present invention to provide a cleaning method and a cleaning device that allow for a short cleaning time.

Sponges (foam molded products) such as polyurethane and polystyrene, strips of rubber, felt, leather, etc., crushed corn stalks, crushed peaches, crushed apricot seeds, crushed walnut shells, etc. The following substances can be mentioned. The preferred bulk density of the solid pieces is 0.01 to 1.2 g/
cm3. The reason for this is that if it is less than 0.01 g/cm 3 , the cleaning time will be longer, and if it exceeds 1.2 g/cm 3 , the plastic lens will be more likely to be damaged. Particularly preferable bulk density is 0.3 to 0.95 g/
cm3. The porosity of the solid piece is preferably about 30% to 99%. The reason is that if it is less than 30%, the plastic lens is likely to be scratched, and if it exceeds 99%, the cleaning effect will be reduced. Particularly preferred materials for the solid pieces are sponge and felt. The reason is that when cleaning plastic lenses with disperse dye attached (usually having a pencil hardness of F to 3H), sponges and felts make the plastic lenses less likely to be scratched, and they do not come into contact with the plastic lenses after being sprayed. This is because sometimes elastic deformation increases the contact area and reduces cleaning time. Further, the shape of the solid piece is not particularly limited, and examples include shapes such as a sphere, a polygonal prism, and an external pyramid.

The type of surfactant is not particularly limited, and known anionic, cationic, and nonionic surfactants are used at a concentration of 0.1% by weight or more. The temperature of the cleaning liquid is preferably 20 to 50°C.

There are two types of solid pieces 2, those with a specific gravity larger than the cleaning liquid 3 and those with a smaller specific gravity.Those with a higher specific gravity than the cleaning liquid 3 sink to the bottom of the cleaning tank 4, and those with a lower specific gravity float on the surface of the cleaning liquid 3. . Therefore, without a dispersion mechanism, solid pieces 2
cannot be uniformly dispersed in the cleaning tank 4. Therefore, in the cleaning device 1 of this embodiment, a nozzle 5 is provided on the side surface of the cleaning tank 4 near the bottom surface, and a pipe 6 that guides a part of the cleaning liquid 3 exiting the cleaning tank 4 to the nozzle 5 is provided. A pump 7 is provided which delivers the cleaning liquid 3 through 6 to the nozzle 5. Then, a part of the cleaning liquid 3 is taken out of the cleaning tank 4 through the pipe 6, sent to the nozzle 5 by the pump 7, and when the cleaning liquid 3 is injected into the cleaning tank 7 by the nozzle 5, the cleaning liquid in the cleaning tank 4 is 3 is stirred and solid pieces 2
is dispersed in the cleaning liquid 3 and does not remain at the bottom.

Nozzles 9, 9' are provided at opposite positions in the cleaning tank 4, and in order to send the cleaning liquid 3 in the cleaning tank 4 to the nozzles 9, 9', the nozzles 9, 9 are inserted from the bottom of the overflow collection part 4a of the cleaning tank 4. A pipe 10 leading to
is provided. The cleaning liquid 3 is then sent to the nozzles 9, 9' by the pump 11 via the pipe 10.
The solid pieces 2 and the cleaning liquid 3 are sprayed by 9'. If the object 8 to be cleaned is placed between the nozzles 9 and 9', the solid pieces 2 and the cleaning liquid 3 will be on the surface of the object 8.
is sprayed so that both sides of the object 8 to be cleaned can be cleaned at the same time. The collision speed of the solid pieces 2 with the object to be cleaned 8 during this jetting is 20 cm.

れた。Embodiment 4 (Submerged injection type) FIG. 4 shows another embodiment of the cleaning device of the present invention. The cleaning device of this embodiment shown in FIG. 4 is the same as the cleaning device of Example 1 shown in FIG. This is different from the cleaning device of Example 1. In the cleaning device of Example 1 shown in FIG. 1, when the cleaning tank 4 is small, the amount of cleaning liquid 3 contained therein is small, and a large amount of solid pieces 2 cannot be put in, and the solid pieces 2 that are sprayed are also small. It becomes less. Therefore, in the cleaning device of this embodiment shown in FIG. 4, an auxiliary tank 12 is provided in order to be able to spray a large number of solid pieces 2 even when the cleaning tank 3 is small. This auxiliary tank 12 receives the cleaning liquid 3 from the overflow collection section 4a via a pipe 10, and agitates the cleaning liquid 3 in the auxiliary tank 12 by a nozzle 5' provided at the bottom of the auxiliary tank 12, thereby removing the solid pieces 2. disperse. The cleaning liquid 3 in which the solid pieces 2 are dispersed is sent to the nozzles 9, 9' by the pump 11 via the piping 10, and is sprayed into the cleaning tank 4 by the nozzles 9, 9'. The auxiliary tank 12 is provided with a partition wall 14 and a mesh filter 15, and by trapping the solid particles 2 with the mesh filter 15, the pump 7 which sends the cleaning liquid 3 to the nozzles 5 and 5' via the piping 6 is activated. Prevent clogging. Incidentally, when a pump that can send the cleaning liquid 3 in which the solid pieces 2 are dispersed is used as the pump 7, similarly to the pump 11, the partition wall 14 and the mesh filter 15 are unnecessary. Further, in this embodiment, the nozzles 5 and 5' are provided at the lower part of the cleaning tank 4 and the auxiliary tank 12 in order to disperse the solid pieces 2 whose specific gravity is higher than that of the cleaning liquid, but the solid pieces 2 whose specific gravity is lower than that of the cleaning liquid are When using these nozzles, it is preferable to provide these nozzles above the cleaning tank and the auxiliary tank. A plastic lens was cleaned using this cleaning device, and similar to Example 1, good results were obtained.

た。Embodiment 5 (Direct injection type) FIG. 5 shows another embodiment of the cleaning device of the present invention. The cleaning device of the present embodiment shown in FIG. 5 is the same as the cleaning device of the second embodiment shown in FIG. 2 in that it is a direct injection type, but unlike the cleaning device of the second embodiment, an auxiliary tank 12 is provided. There is. This auxiliary tank 12 is integrated with the cleaning tank 4, receives the cleaning liquid 3 after being sprayed onto the object to be cleaned 8 via a passage 13, and the auxiliary tank 12
The cleaning liquid 3 in the auxiliary tank 12 is stirred by the nozzle 5 provided at the top of the tank, and as a result, the solid pieces 2 are dispersed. The cleaning liquid 3 in which the solid pieces 2 are dispersed is sent to the pump 1 via the pipe 10.
1 to the nozzles 9, 9', and the nozzles 9, 9' spray the cleaning target 8 in the cleaning tank 4. The partition wall 14 and the mesh filter 15 are provided in the auxiliary tank 12, as in the case of the cleaning device of the fourth embodiment shown in FIG. In the cleaning device shown in FIG. 5, the bottom of the cleaning tank 4 is inclined toward the passage 13 to the auxiliary tank 12.
The cleaning liquid 3 is designed to smoothly flow from the cleaning tank 4 to the auxiliary tank 12. A plastic lens was cleaned using this cleaning device, and similar to Example 1, good results were obtained.
