Abstract

A work insertion device that can be constituted as a small, low-cost device has a structure where a transfer disk having many storage holes formed through its outer periphery part is placed such that its rotation center line is inclined upward to form a sharp angle α with a vertical line and that some of the many storage holes are positioned in the work storage chamber. The works stored in bulk state in the work storage chamber are directly stored in some of the many storage holes positioned in the work storage chamber by utilizing the intermittent turning of the transfer disk.

First claim

I claim:

1. A work insertion device for sequentially inserting works such as electronic components into concaved parts arranged side by side on a tape, said work insertion device comprising:
a transfer disk whose rotation center line is inclined upward to form a sharp angle with a vertical line, and which has many storage holes capable of storing the works wherein the holes are formed through an outer periphery part and arranged at an equal angular interval in a circumferential direction, where the many storage holes are evenly divided into multiple storage hole groups each including multiple storage holes;
a disk driving mechanism for intermittently turning the transfer disk in units of an angle formed by two lines connecting centers of two adjacent storage hole groups on the transfer disk and a rotation center of the transfer disk;
a work storage chamber capable of storing many of the works in bulk state, which is positioned in a manner facing upward-facing openings of the multiple storage holes constituting at least one storage hole group on the transfer disk, and which is used to directly store works in the multiple storage holes constituting the storage hole group, through the upward-facing openings of the holes, as the transfer disk turns intermittently;
a work anti-drop means for preventing the works stored in the multiple storage holes constituting the storage hole group from dropping out through downward-facing openings of the holes as the storage hole group on the transfer disk in which works are already stored travels to a work insertion location away from the work storage chamber;
a work push-out means for forcibly pushing out the works stored in the multiple storage holes constituting the storage hole group through the downward-facing openings of the holes when the storage hole group of the transfer disk in which works are already stored stops at the work insertion location; and
a work guiding means, which includes multiple guiding passages that incline downward toward the multiple concaved parts in the tape from the downward-facing openings of the multiple storage holes constituting the storage hole group stopped at the work insertion location, for guiding the works pushed out through the downward-facing openings of the multiple storage holes, into the multiple concaved parts, through the multiple guiding passages.

2. A work insertion device according to claim 1 , wherein the work push-out means includes a positive-pressure air passage for applying positive-pressure air in the multiple storage holes constituting the storage hole group stopped at the work insertion location, with the positive-pressure air flowing from the upward-facing openings to the downward-facing openings of the respective holes.

3. A work insertion device according to claim 1 , wherein the work guiding means includes a negative-pressure air passage for applying negative-pressure air in the multiple guiding passages, with the negative-pressure air flowing from the upward-facing openings to the downward-facing openings of the respective passages.

4. A work insertion device according to claim 1 , wherein the multiple guiding passages have enough length to store multiple works inside in succession.

5. A work insertion device according to claim 4 , wherein the work guiding means includes a second negative-pressure air passage for controlling insertion into the multiple concaved parts, respectively, of first works among the multiple works stored in the multiple guiding passages.

6. A work insertion device according to claim 4 , wherein the work guiding means includes a moving rod for controlling insertion into the multiple concaved parts, respectively, of first works among the multiple works stored in the multiple guiding passages.

7. A work insertion device according to claim 4 , wherein the work guiding means includes a moving suction nozzle for controlling insertion into the multiple concaved parts, respectively, of first works among the multiple works stored in the multiple guiding passages.

8. A work insertion device according to claim 1 , further comprising:
a storage good/bad detection means for separately detecting whether storage of each work in the multiple storage holes constituting the storage hole group is good or bad when the storage hole group on the transfer disk in which works are already stored stops at a work storage good/bad inspection location before the work insertion location; and
a work returning means for returning to and storing again in the work storage chamber all works stored in the storage holes constituting the storage hole group when even one badly stored work is detected by the storage good/bad detection means.

9. A work insertion device according to claim 1 , wherein the work is an electronic component and that said work insertion device further comprises:
a characteristics good/bad detection means for separately detecting whether characteristics of each work in the multiple storage holes constituting the storage hole group are good or bad when the storage hole group on the transfer disk in which works are already stored stops at a work characteristics good/bad inspection location before the work insertion location;
a work returning means for returning to and storing again in the work storage chamber the works of good characteristics among the works stored in the storage holes constituting the storage hole group when even one work of bad characteristics is detected by the characteristics good/bad detection means; and
a bad work disposal means for disposing, when even one work of bad characteristics is detected by the characteristics good/bad detection means, of the work of bad characteristics among the works stored in the storage holes constituting the storage hole group, instead of returning it to the work storage chamber.
