'The optical can be made by molding. The lens can be produced by injection molding the molten plastic material into the gas and molding it. Further, in the case of the glass lens, a glass block which is called a preform is shaken and placed in a mold, and is molded by glass molding by press-pressing with a mold in a state where the film is softened by heating. By manufacturing the lens by such molding, in addition to the simplification of the process by conventional grinding, polishing, etc., in the case of an aspherical lens or the like, it is possible to produce the desired shape by forming the mold into a desired shape. The advantages of the lens. ^ 〇 In recent years, glass materials with various optical properties have been produced on the market as preforms of various shapes and sizes as materials for glass molding. A precision glass molding technique in which a glass lens which moves the preform to a mold and is molded by heating and softened without grinding is also developed. This technique first requires the formation of a preform. As the preform, a precision clot or a polishing lens preform (hereinafter referred to as "molding material") can be used. The surface of the precision clot is close to the mirror state, and the size is also close to the state of the target lens, especially the use of a slightly spherical precision clot. For the production of a slightly spherical preform, it is known that the molten glass is dripped in a liquid. TF975311 5 200906740 f 'There is also a charge for the bottom of the glass, so that the dripped glass is floated in the air. A method of cooling and solidifying. The pre-formed lining of the lapping lens is formed into a substantially spherical shape by conventional heat forming, grinding, and grinding. The precision clot obtained by molding such a preform or the polished through-form preform ' is heated and pressed in a molding apparatus to obtain a lens molded article. In the 3L dressing, the whole system automatic parent is 'in order to mass-produce', for example, it is known that the molding material is automatically transferred to the molding die, the press molding is performed, and the obtained lens molded product is carried out from the molding die.

The first operation is a step of moving the lens into the tray 16 from the recovery table 18, which corresponds to the fourth step of the present invention. The twelfth job is replaced with the i-th hand and after the extraction. In the thirteenth operation, the tray table 16 accommodating the lens molded product % is moved to the molded product tray stacking table 15 to be collected. However, if the work described in FIG. 2 is performed in sequence, the preparation work other than the first molding work is performed. Since it takes a lot of time to wait for molding, therefore, in order to effectively continuously mold the lens molded product 34, as shown in Fig. 3, the first hand and the second head are used in the third hand 27-body for different operations. The portions 29 and 30. The engagement of the third hand 27 is at the end of the linear support portion 31, and the !! and the second head portion (9) and the TF975311 12 200906740 are respectively disposed at different positions on the other end. As shown, for example, at time t1, between, and at the sixth job, these operations can also use one third (one) 27: the time can be shortened by omitting the hand replacement operation. Second, the same can be used. The second hand 26 performs the first "work and the second work; therefore, time t3 as shown in FIG. t4 ^ industry, and with the same first 7⑽ molding) operations of: feeding molding time 'so preferred. In this case, the f2 hand; = has the exclusive holding means 26a, so that, for example, 9 can be moved from the arbitrary housing portion of the tray 23 to the supply table 17 =: 1 lens molded product 34 from the recovery table 18 Moving to the tray After moving the plurality of molding materials 9 from an arbitrary one, the same number of lens moldings are sequentially moved to the empty housing portion 23a. In this way, alternate or staggered 3 jobs and 11th jobs. In the tray 23 of the present embodiment, the tray 23 of the present embodiment is provided with a plurality of accommodating portions formed in the mold 19. Therefore, after the third and seventh operations of the eve-day, the work of transporting the tray 23, that is, the thirteenth job, and the i-th can be performed, for example, between the times tj and t6 shown in FIG. operation. Further, since the twelfth work, the fourth (fourth), and the first work are also performed by the same i-th hand 25, it is preferable to carry out the work simultaneously with the disk 7 (molding). The second embodiment of the present invention and the second head portions 29 and 3 are respectively mounted on the same line as the card 5 portion 33 and have different lengths. However, the present invention TF975311 13 200906740 is not limited thereto, as shown in FIG. The hand (4) at different positions on the concentric circle may be the t 3 〇 engaging portion 33, and the two supporting portions 41 protruding in a V shape may be supported by the first and second head portions 29 and 30. . Then, the second embodiment can be used. The right-angled coordinate arm 32 can also be used arbitrarily using a cylindrical coordinate robot arm or a pole seat; a conventional robot arm such as a joint arm. In the above embodiments, the glass arm molding apparatus is described. However, in the present invention: == into: : resin material to obtain a molded product of a resin molded product: Molded products other than lenses.
