BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for delivering a work to each receiving part when the receiving parts of the work are three-dimensionally arranged in upper and lower stages.

[0002]

2. Description of the Related Art For example, in Japanese Unexamined Patent Publication No. 6-9141, as schematically shown in FIG. 3, an elevator 2 which vertically moves up and down is provided at a work carrying-out end of a common transport path 1, and a large number of shelves are mounted on the elevator 2. Is provided, and the work is sequentially distributed from the common transport path 1 to each shelf board, and each work board is supplied to the plurality of work receiving sections 3a, 3b, ...

[0003]

However, in the above-mentioned work feeding apparatus, the elevator is intermittently stopped, and the works are mounted one by one on each shelf board of the elevator from the common transfer path at each stop. Therefore, it is not possible to improve the delivery speed, and there is a limit to the improvement of the processing efficiency after the work receiving parts arranged in the upper and lower stages.

Further, in the above-mentioned conventional example, since the work is transferred from the common transfer path to the elevator at a right angle,
There is a problem that it is difficult to mount a work that has been transported at a constant feed speed on a common transport path at a fixed position on each shelf of the elevator, and often the work causes irregular movement due to inertia, resulting in defective mounting. are doing.

SUMMARY OF THE INVENTION According to the present invention, in a device for delivering a work to a work receiving part arranged in a multi-stage vertically as described above, the problem inherent in the device is appropriately solved. It is an object.

The upper and lower multi-stage work feeding apparatus according to the present invention is provided with a common conveyance path for conveying the works at intervals in the feeding direction, and a plurality of inclined conveyances extending obliquely upward from the work supporting surface of the common conveyance path. With a road.

The inclined conveying paths are arranged in a plurality of upper and lower stages at intervals in the work feeding direction by the common conveying path.

Then, a work transfer gate is arranged at the lower end of each inclined conveyance path and the connecting portion of the common conveyance path. This work transfer gate is displaced to a position for transferring the work on the common conveyance path to each inclined conveyance path and a position for allowing the passage of the work,
By selectively displacing each gate to the work transfer position, the work is selectively transferred to each inclined conveyance path.

The work transfer gate is composed of, for example, a turning lever pivotally supported so as to turn to the upper and lower sides of the work supporting surface of the common transport path. The rotation lever forms a work guide surface which is inclined toward the lower end entrance of the inclined conveyance path by the upward rotation. The workpiece on the common conveyance path is turned obliquely according to this inclined guide surface and is smoothly transferred to the inclined conveyance path.

Further, as a means for further ensuring the transfer of the work from each of the work transfer gates to each of the inclined transfer paths, the work supplied by the work transfer gate is elastically provided at the lower end entrance of each of the inclined transfer paths. It is equipped with a work intake means which is captured by and is used for each inclined conveyance path.

Further, a work take-out means for catching a work and sending the work horizontally to each work receiving part arranged in a plurality of upper and lower stages is provided at the upper end outlet of each of the inclined conveying paths.

[0012]

According to the present invention, for example, a plurality of works are supplied to the first inclined transfer path by the first work transfer gate, and immediately thereafter, the works are supplied to the second inclined transfer path by the second work transfer gate. Can embark on. That is, while the work is being conveyed toward the first work receiving portion on the first inclined conveyance path, the work can be continuously supplied to the second, third, ...

As a result, it is possible to greatly improve the delivery speed of the work from the common transfer path to each of the inclined transfer paths, and it is possible to achieve an improvement in the processing efficiency after the above-mentioned work receiving sections.

Further, the work sent horizontally on the common carrying path can be transferred only by changing the direction to the tilt angle according to the tilted carrying path, and the irregular movement due to the inertia of the work at the transferring part can be performed. The work can be smoothly transferred from the common transfer path to each inclined transfer path without causing harmful positional deviation.
