Description

[Detailed Description of the Invention] The present invention relates to an automatic feeding device that stably transports and supplies minute parts such as screws for wristwatches.

The present invention improves the stability of parts supply in a vibrating parts supply device that transports and supplies minute parts such as screws for wristwatches, by integrating the part alignment part and the part extraction part on the track instead of separating them. This invention relates to an automatic feeding device that is high in height and has a simple structure.

The purpose of the present invention is to improve the stability of transport and supply of micro parts.

Another objective is to simplify the supply structure and reduce production costs.

The conventional automatic feeding device is shown in Fig. 1 and Fig. 2 (Fig. 1 n-n).
As shown in Figure 3 (cross-sectional view along the line m-m' in Figure 1), in the bowl 1 of the vibrating parts feeder, the amount of parts is first limited to an appropriate amount in advance, and a certain amount of In order to perform alignment, it is necessary to cut the cross-sectional shape of the track section 7 into a V-shape or other shape that matches the part shape, or to make other modifications to the track section 7 that match the parts. The disadvantage is that it is limited.

In addition, in the chute section 2, a sorting section 3 and a component reservoir bone 4 are provided.
At this point, parts that do not have a desired orientation or an excess amount are removed, and the parts are finally aligned in one desired orientation and are taken out from the parts extraction section 5. Congestion due to incomplete removal of objects in a position that does not meet the desired position in section 3, or incomplete removal of excess amounts, and overlapping of components at the entrance of cover 6, which moves from sorting section 3 to component storage bone 4. occurrence of the phenomenon,
Alternatively, there are factors that impede conveyance and supply, such as the occurrence of a phenomenon of extrusion of components at the component take-out portion 5 of the component storage frame 4 due to the pressure of components lined up from the track section to the chute section, or factors due to instability.

Further, regarding the chute portion 2, it is important to consider accuracy, wear resistance, etc., and the manufacturing cost is relatively high.

The present invention eliminates the above-mentioned drawbacks, and will explain the embodiment with reference to the drawings. In FIGS. It is a pipe-shaped or rod-shaped push-up rod that penetrates through the shaft and is set to move up and down with a certain stroke 1.

Depending on the shape and dimensions of the part, set the inner and outer diameters of the pipe of the push-up rod so that only the required position is held in a stable state, or adjust the shape of the track surface of the take-out section and the end surface of the push-up rod. Set the recess according to the

Among the parts being conveyed randomly and continuously on the track 7, only those in the required position are held in a stable state in the pipe hole or recess of the push-up rod 8, and the push-up rod is then moved upward. By being pushed up, it is completely separated from the flow of parts on the track and held in a very stable condition.

Although not shown, if the push-up rod is moved up and down intermittently at regular intervals using other power, it is possible to automatically feed minute parts in an extremely stable manner.

Regarding the track section 7, there is no need for any functions such as regulation and alignment of the transport amount of parts, and it is sufficient to simply transport the parts.
There are few restrictions on the cross-sectional shape, and almost no other workmanship is required to match the shape of the part.

In addition, it is structurally simple, requires relatively little precision, and is inexpensive to manufacture.

Even when it is necessary to take out two or more parts at the same time, it can be easily done by installing the required number of push-up bars at appropriate positions on the track.

As described in detail above, according to the present invention, automatic conveyance and supply of not only minute parts such as screws for wristwatches but also other stepped parts can be carried out reliably with a simple and inexpensive mechanism.
