【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. The component supply device supplies the reinforcing ring of the oil seal, which has been conveyed by the conveyor, into the mold as in the above-mentioned conventional technique.

In FIG. 1, the component supply apparatus indicated by reference numeral 1 as a whole is positioned directly above the conveyor e, supported by a transfer apparatus such as an actuator (not shown). At this point, the reinforcing ring a on the conveyor e is gripped (FIGS. 1 to 5), and is moved right above the mold by the transfer device to fit the reinforcing ring a into the lower mold c (FIGS. 6 to 5). (Fig. 8).

In the configuration of FIG. 1, reference numeral 2 is a drive source such as a hydraulic cylinder fixed to the block 3. When the drive source 2 drives, the rod 4 moves up or down along the central axis thereof. A plate-shaped moving member 5 is arranged on the outer peripheral side of the rod 4 so as to be relatively movable in the vertical direction, and a large diameter retaining portion 6 formed at the lower end of the rod 4 prevents the rod 4 from falling off. There is. The moving member 5 is pressed against the retaining portion 6 by a spring member 7 such as a coil spring, and is also prevented from rotating by a plurality of rod-shaped retaining members 8. A plurality of rod-shaped stoppers 9 are provided so as to project downward on the lower side of the moving member 5. When the driving source 2 drives and the rod 4 descends, the moving member 5 descends accordingly. If there is something below the stopper 9 and the stopper 9 abuts on this, the moving member 5 descends. Stops, and after that, only the rod 4 continues to descend while compressing the spring member 7. In this embodiment, this something is a stopper block f fixed to the lower mold c as described later. On the lower end of the stopper 9, there is provided a pin-shaped projection 10 for positioning that engages with the hole g of the stopper block f. A plurality of leaf springs 11 for holding the reinforcing ring a on the conveyor e are attached to the lower center of the moving member 5. As shown in FIGS. 2 and 3, four leaf springs 11 are bolted to an annular mounting member 12 in an even arrangement and attached to the moving member 5 via the mounting member 12. The distance between the two leaf springs 11 facing each other is set to be slightly smaller than the outer diameter dimension of the reinforcing ring a, and when it descends, it elastically bends to grip the reinforcing ring a from its outer peripheral side. The number of leaf springs 11 may be two, three, five or more, and the point is that the reinforcing ring a can be elastically gripped between them. Alternatively, a plurality of leaf springs 11 having different intervals may be prepared and replaced according to the size of the reinforcing ring a. A bottom cup-shaped component pressing portion 13 is bolted to the lower end of the rod 4. The component pressing portion 13 pushes the reinforcing ring a gripped by the leaf springs 11 from between the leaf springs 11 and fits into the lower mold c when the rod 4 is further lowered after the moving member 5 is stopped descending. ..

FIG. 1 shows a state in which the component supply device 1 is supported by a transfer device (not shown) and is positioned right above the conveyor e as described above. This is the initial posture, and the component supply device 1 operates as follows after the start. A. The driving source 2 is driven downward, the rod 4 and the moving member 5 are lowered together, and the leaf spring 11 holds the reinforcing ring a on the conveyor e (FIG. 4). At this time, the descending distance between the rod 4 and the moving member 5 is limited by the stroke of the drive source 2 so that the leaf spring 11 does not contact the conveyor e. B. The drive source 2 is driven upward, the rod 4 and the moving member 5 are raised together, and the reinforcing ring a gripped by the leaf spring 11 is lifted (FIG. 5). C. The component supply device 1 is moved to a position right above the lower mold c of the mold by the transfer device (FIG. 6). D. The drive source 2 is driven downward, and the rod 4 and the moving member 5 are lowered together. When the rod 4 and the moving member 5 descend to some extent, the stopper 9 comes into contact with the stopper block f, and the descending of the moving member 5 is stopped (FIG. 7). E. The lowering of the rod 4 is continued while compressing and contracting the spring member 7, and the component pressing portion 13 pushes out the reinforcing ring a held by the leaf spring 11 from between the leaf springs 11 and fits it into the lower mold c (FIG. 8). ).

Therefore, according to the component supply device 1, it is possible to grip the reinforcing ring a on the conveyor e and fit the reinforcing ring a into the lower mold c by itself. The drive source 2 makes only one reciprocation on the conveyor e and on the lower mold c, and the reinforcing ring a can be gripped and fitted by such a simple operation, thereby reducing the working time. It can be shortened. In addition, the structure of the device can be simplified, so that an inexpensive device can be provided, and an excellent device with less mechanical and control troubles can be provided. Further, the component supply device 1 can supply various components to various mating members, not only for supplying the reinforcing ring a into the mold. As an example, as shown in FIG. 9, the inner ring h of the oil seal is used as a supply component, the reinforcing ring a is used as a mating member, and the inner ring h is fitted to the inner peripheral side of the reinforcing ring a.
