The processing apparatus shown in FIG. 2 is a resin molding apparatus having a structure in which dies 26 and 28 each having an upper and lower mold are connected in two upper and lower stages. On the base 14 of this apparatus, a plurality of (four) rods 22 that are long in the vertical direction are erected. The die plate 16 is fixed to the tip side of each rod 22, and the die plates 18 and 20 are arranged between the die plate 16 and the base 14 side so as to move up and down along the rod 22. . The upper mold 26 is assembled between the die plates 16 and 18, and the lower mold 28 is assembled between the die plates 18 and 20.
By driving and controlling the hydraulic cylinder 24 assembled to the base 14, the die plate 20 is raised and the lower mold 28 is clamped, and then the die plate 18 is pushed up and the mold 26 is clamped. Is done. In the state where these molds 26 and 28 are closed, the molten resin is individually injected from the injection unit 30 into the respective interiors, whereby the two push buttons 10 are formed in the upper mold 26, and the lower mold is formed. In 28, the holder 12 is molded.

Push button 10 and the holder 12 that is molded in a mold 26, 28 is conveyed as indicated by the arrows in FIG. 2 are assembled as described above, and a push-button 10 and the holder 12 being conveyed An additional function (tampo printing or grease application) for depositing the substance is performed . The arrows in FIG. 2 indicate the basic concept of the present invention, and details will be described below.
As shown in FIG. 3, on the left side of the processing apparatus, a chuck A, which is a component conveying apparatus, and a chuck B composed of a pair of upper and lower chucks B1, B2 are arranged. When the chuck B does not need to be distinguished from the chucks B1 and B2, these will be collectively referred to as the chuck B.

In the processing apparatus shown in FIG. 3, after the two push buttons 10 and the holder 12 are molded, the respective dies 26 and 28 are opened, the chuck A is in the standby position, and the chuck B is in the previous molding. In the cycle, the two push buttons 10 formed by the upper mold 26 are held. Here, both chucks A and B enter between the upper and lower molds of the open molds 26 and 28, respectively (FIG. 4). Both the chucks A and B move downward, and the chuck A grips the two push buttons 10 formed by the upper mold 26 (FIG. 5). On the other hand, the chuck B moves further downward along the guide 40, and the push button 10 is assembled to the holder 12 formed by the lower mold 28 (FIG. 6).
The chuck B actually holds the push button 10 in the upper chuck B 1, and when the push button 10 is assembled to the holder 12, the lower chuck B 2 has its finger in the holder 12. It is located on the side surface and holds the holder 12 as it is.

Next, the chucks A and B are both lifted (FIG. 7) and moved from the inside of the molds 26 and 28 to the outside (FIG. 8). Thereafter, the chucks A and B both move down greatly, releasing both the push button 10 held by the chuck A and the holder 12 to which the push button 10 held by the chuck B is assembled (see FIG. 9). Then, the holder 12 to which the push button 10 is assembled is carried out to the next process, and both the chucks A and B are greatly raised to return to the state shown in FIG.
