And a first blocking pin 149a and a second blocking pin 149b that can be inserted into the first hole 134a and the second hole 134b.

The body 146 is disposed at one end of the guide part, and includes a guide passage 145 for guiding a screw passing through the first blocking pin 149a and the second blocking pin 149b. The guide passage 145 is connected to a screw dispenser (not shown) through which the screw is used through the screw outlet 143.

On the other hand, as shown in Figure 4, the movable plate 148d, which is provided in the connecting plate 148c of the movable part, provides a moving path of the screw when the connecting plate is aligned with the guide passage 145 of the main body 146 in the connecting plate. ).

As shown in FIG. 4, the first blocking pin 149a and the second blocking pin 149b are larger than the diameter of the threaded portion of the screw (the outer diameter of the threaded portion: not shown) and the head portion of the screw ( It is spaced apart in the longitudinal direction of the slide groove 131 at an interval t smaller than the diameter of SH).

Referring to FIG. 2, an actuator 144 is provided on a side of the bracket 142 to provide power for causing a reciprocating motion of the movable part, and a leg part for maintaining and supporting the inclination of the supply part 150 constantly. 141 is connected to the bracket 142. In addition, the main body 146 is disposed with a pneumatic connection 160 for providing air pressure so that the guided screw can be transported to the screw dispenser.

On the other hand, the movable hole 148d of the movable part and the guide passage 145 of the main body are arranged to be aligned with each other when the second blocking pin of the movable part is opened.

As a variant embodiment, although not shown in the drawing, the distance between the first blocking pin 149a and the second blocking pin 149b can be adjusted, and thus the first hole 134a into which the blocking pin is inserted. ) And the second hole 134b may also be formed to have a slot shape having a long shape instead of a circular hole so as to correspond to the first blocking pin and the second blocking pin whose positions are variable. In this case, it is possible to provide a screw feeder that can be used for screws of various specifications without having a separate screw feeder in accordance with the specifications of the screw to be supplied.

In addition, if the distance (d) between the first side plate 132a and the second side plate 132b in the guide unit 130 can also be adjusted according to the specifications of the user screw can be used to supply screws of various specifications Will be.

The following describes the operating state of the screw feeder having the structure as described above.

The plurality of screws irregularly contained in the container 110 in any direction are lifted from the container by the screw attitude control unit 120 so that the screw head portion is directed upward and the thread portion of the screw is aligned in a constant direction. The plurality of aligned screws slides by gravity along the guide part 130 connected to the screw attitude control part 120.

On the other hand, as shown in Figure 3, the screw slides to the synchronization unit 140, the screw disposed in the foremost waits to prevent the further progression is caught by the first blocking pin (149a) of the synchronization unit disposed in the foremost As the screw stops, it waits in a line, preventing many screws from moving behind it.

At this time, as shown in FIG. 4, the first blocking pin 149a does not block the screw as the movable part moves to the right side in the drawing, but instead, the first blocking pin 149a is spaced apart from the first blocking pin 149a by t. The second blocking pin 149b blocks the foremost screw. At this time, only one screw may be caught in the interval of t.

Thereafter, as shown in FIG. 5, when the movable part moves to the left again and the blocking action of the second blocking pin 149b is released, the foremost screw is dropped into the guide passage 145. At this time, since the movable hole 148d formed in the connecting plate 148c is aligned with the guide passage 145, the screw entering the guide passage 145 can reach the screw dispenser by the force of external air pressure. do.

On the other hand, because only one of the frontmost screw is supplied and the screws waiting in line behind the foremost screw have to stay in the guide groove 131 as it is, the first blocking pin 149a is again shown in FIG. 5. The guide groove 131 is blocked. By repeating the reciprocating motion of the movable portion, the synchronization unit 140 of the supply unit 150 can supply the screws one by one at the time of electricity. The timing of supplying one screw in a single reciprocating motion is synchronized with a compressor that provides external air pressure, which provides the air pressure in time for the screw to move to the dispenser.
