Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts feeder for flanged parts, and is used in a field in which the front and back are always aligned.

[0002]

2. Description of the Related Art As a conventional technique, when a flanged component, which has been moved by vibration along a passage plate on the inner circumference of a circular bowl, faces downward, it is caused to fall from the passage plate to the inside of the circular bowl. On the other hand, the face-up parts are transferred to the delivery groove as normal and are delivered.

[0003]

With the above-mentioned conventional technique, since the parts facing down fall to the inside of the bowl, the number of the parts normally sent out face up, in other words, the normal rate decreases, Therefore, the delivery amount per operation vibration time of the parts feeder is low. This is disadvantageous for saving power consumption, and moreover, the generation time of vibration noise is prolonged, which is not good for the factory environment.

Means for Solving the Problem and Its Action The present invention is provided to solve the above-mentioned problems.
In a type in which parts are rolled out from a passage plate formed along the inner circumference of a circular bowl and sent out to a delivery groove, the bottom plate of the delivery groove at the part where the parts fall has a steep inclination that its outer peripheral side becomes higher, The inclination gradually becomes gentle in the delivery direction, and the slender guide protrusions are arranged at a low inclination position of the bottom plate at the parts falling position, and are gradually displaced to the high inclination position of the bottom plate in the delivery direction. The parts that have moved the passage plate face up face down into the delivery groove as they are, the flanges catch on the guide protrusions, and as the guide protrusions gradually move to a higher position, they become horizontal. Or, it is sent out in a slightly inclined posture. On the other hand, the parts that have moved the passage plate face down face still fall into the delivery groove and hit the bottom plate with a steep slope, and the steep slope causes the flange to slip and reverse, catching on the guide protrusion and moving with a slope. Then, when the guide projection is finished, it will be in a normal face-up position. It should be noted that "face-up" means that the flange is on the lower side, and "face-down" means the opposite.

Embodiments The parts in the following embodiments are exemplified by a flanged nut 3 composed of a nut body 1 and a flange 2 as is apparent from FIG. Explaining the parts feeder 4 with reference to FIGS. 2 and 3, a vibrating section 6 is installed on the lower side of the circular bowl 5, and a passage plate 7 that gradually rises in the counterclockwise direction along the inner circumference of the bowl 5 is provided. It is provided and continues to the delivery section 8 around the end of the passage plate 7,
The delivery pipe 9 is connected to this.

FIG. 1 is a partial plan view showing the delivery section 8 in an enlarged manner. An outer wall plate 10 of the bowl 5, an outer plate 11 of the delivery section 8 and a bottom plate 12 form a delivery groove 13. ing. The vicinity of the terminal end of the passage plate 7 overlaps with the vicinity of the starting end of the delivery groove 13, and this overlapping portion is defined as the component falling point 14. FIG. 4 is a vertical cross-sectional side view in the vicinity of the parts falling point 14, in which the bottom plate 12 is inclined so that the outer peripheral side is higher, and in the vicinity of the parts falling point 14, there is a marked steep inclination. As is clear from FIGS. 4 and 5, the passage plate 7 is slightly lowered on the outer peripheral side thereof, and the peripheral wall plate 15
When it moves along (see FIG. 1) and approaches the parts falling point 14, it slides down into the delivery groove 13 due to the inclination of the passage plate 7, and the passage plate 7 and the outer wall plate 10 form a corner portion 16. . The inclination angle in the vicinity of the parts falling point 14 is such that when the nut 3 rolls down in the delivery groove 13 and assumes the posture as shown by the two-dot chain line in FIG.
Upper surface of the base plate contacts the corner portion 16, while the flange 2 is connected to the bottom plate 1.
The angle Θ formed by the flange 2 and the bottom plate 12 is set to form an acute angle in a state where the flange 2 and the bottom plate 12 are in contact with each other. Bottom plate 12
Is gradually inclined in the delivery direction, that is, as it goes downward in FIG. 1, and is approximately horizontal in the vicinity of FIG. Further, the outer plate 11 also gradually inclines to the outside as the bottom plate 12 gradually inclines.

Explaining the elongated guide protrusion 17,
This is an elongated and gently curved steel plate welded to the bottom plate 12, and is arranged at a low inclined position of the bottom plate 12 in the vicinity of the parts falling point 14 and gradually displaced to a high inclined position in the delivery direction. As is clear from FIGS. 4 to 7, the parts are mounted in a substantially upright posture in the vicinity of the parts falling point 14 and deformed so that they gradually lie in the delivery direction. In other words, they are twisted little by little. I will go.

Next, the operation of the bowl 5 will be described.
Since the whole is vibrated, the nut 3 moves on the passage plate 7 in the counterclockwise direction (see FIGS. 1 and 3), and comes close to the parts falling point 14.
At this time, when the nut 3 is face-up, it is shown by a solid line in FIG. 4 and subsequent figures, and when the nut 2 has just fallen at the component falling point 14 in FIG. 4, the flange 2 comes into contact with the corner portion 16 and the guide protrusion 17. In addition, the corners of the nut body 1 are in contact with the bottom plate 12. Since the bottom plate 12 is gently inclined toward the delivery direction and the height position of the guide projection 17 is also increased at the same time, the nut 3 is rotated in the clockwise direction as shown in FIGS. It is sent out in.

When the nut 3 moves on the passage plate 7 with the face down, the nut 3 falls into the delivery groove 13 at the parts falling portion 14, as shown by the chain double-dashed line. That is, the upper surface of the nut body 1 contacts the corner portion 16, and the flange 2 is attached to the bottom plate 12.
To contact. Since such contact is a momentary state and the angle Θ is an acute angle, the flange 2 slips on the surface of the bottom plate 12 and rotates counterclockwise, so that the flange 2 is guided to the guide protrusion 17 as shown in FIG. The bottom plate 12 is caught as shown in FIG.
Since the guide projection 17 is displaced to a high position while the inclination of the nut 3 becomes gentle, the nut 3 is fed in a state shown in solid lines in FIGS.

[Effects] According to the present invention, even if the front and back of the passage plate are moved separately, the front-facing ones can be fed into the delivery groove as they are, and the back-facing ones can be turned upside down in the vicinity of the parts where the parts fall. Since all the parts on the passage plate are changed, they fall into the discharge groove and are discharged. Therefore, unlike the prior art, the one having an abnormal orientation is not returned to the inside of the bowl, and the efficient component supply is achieved. In particular, it is extremely effective in minimizing the noise and power consumption of the parts feeder. Furthermore, since the inclination of the bottom plate is gradually eased from a steep angle, and the mounting position of the guide projection is gradually changed as described above, it does not cause a malfunction. Realizes highly reliable parts delivery. Then, the guide protrusion stands up near the part where the component falls, but is gradually laid down, that is, twisted as it goes in the delivery direction, so that the component shown by the chain double-dashed line in FIG. 6 gets over the guide protrusion. As shown by the solid line in FIG. 7, smooth displacement is possible, which contributes to the establishment of stable operation.
