Description

[Detailed description of the invention] Technical field of the invention The invention relates to a parts sorting device for aligning and transporting parts, and more specifically, it relates to a parts sorting device for aligning and transporting parts, and more specifically, it relates to a parts sorting device for aligning and transporting parts, and more specifically, it relates to a parts sorting device for aligning and transporting parts, and more specifically, a device for aligning and transporting parts. The present invention relates to a parts sorting device for aligning and transporting ring-shaped parts in a predetermined posture.

Conventional technology Vibrating feeders have traditionally been used to handle parts to automatic assembly machines, but in this case, it is relatively easy to align and transfer items with no directionality, such as disk parts, and the orderly transfer efficiency is also low. expensive.

However, when the outer circumferential shape of a component is uneven and has directional properties, that is, a component that is aligned and transferred on the track of a vibrating feeder, there are many directional postures as seen from the outer circumferential shape, for example, as shown in FIG. When selecting only the C-clip W in which the notch Wa is in contact with the track T and supplying it to the assembly machine, the C-clip W transferred on the track is circular; Moreover, by having the notch Wa, the center of gravity of the C-clip W moves to the side opposite to the notch Wa, so the transport attitude of the C-clip W on the track T is such that the notch Wa is relative to the track T. Most of them are located at the top. Therefore, the supply rate of C-clips in the desired orientation is extremely low, resulting in a shortage of parts to the assembly machine, which impedes automatic assembly.

Also, because a part of the C-clip is cut out, and because it is formed by bending and then subjected to heat treatment such as quenching, it is flatter than those that are punched like E-rings. Because of their poor carrier strength, they tend to get tangled with each other, and the tangles cannot be untied during sorting and feeding.

Therefore, conventionally, a ring-shaped part such as a C-clip with a partially cut off part has a bar member 1 corresponding to the inner diameter of the C-ring W and a bar member 1 attached to the bar member 1, as shown in FIG. At present, a magazine 3 is prepared in which a protrusion 2 is formed with which the notch Wa of the C-clip W engages, and the C-clip W is fitted into the magazine 3 by hand.

Summary of the invention The present invention solves the above-mentioned conventional problems, and consists of a jump table of a predetermined length that is inclined at a predetermined upward slope in the direction of movement of the parts in the parts storage container that is transferred to the parts by vibration. A tangling release gate is provided for dropping and colliding the parts from the jump table onto the parts transfer path, and an air blow gate and a total shape dropping gate are provided for correcting the posture of the parts in the middle and at the end of the parts alignment transfer track, and each of these gates Provided is a vibratory feeder that can efficiently align ring-shaped parts from which a portion of a C-clip or the like has been removed in a desired posture by passing the ring-shaped parts through the feeder, and improve the supply rate of ring-shaped parts in the desired posture. The purpose is to

Embodiments of the invention Hereinafter, specific embodiments of the invention will be described with reference to the drawings.

3 to 8 show an example in which the parts sorting device of the present invention is applied to a bowl-type vibrating feeder, and 10 is a base constituting the vibrating feeder;
Reference numeral 11 denotes a vibration isolating material attached to the lower surface of the base 10, and the lower ends of a plurality of leaf springs 12 inclined in the same direction are fixed to the outer periphery of the base 10. A pedestal 13 is fixed, and a bowl 14 is integrally mounted on the pedestal 13. Further, an electromagnet 15 is installed at the center of the base 10, and this electromagnet 1
5 is directly excited by the power supply frequency, the pedestal 1
A torsional vibration having horizontal and vertical components is generated in the bowl 14 including the bowl 3.

The bowl 14 has a bottomed hopper shape, and a spiral component transfer track 16 is formed on the inner wall surface of the bowl 14 from the bottom surface 14a toward the top end. In addition, the above-mentioned track 16
As shown in FIG. 5, on the bottom side wall surface of the bowl 14 facing the starting end 16a of the bowl 14, there is a C-clip consisting of a jump base 17a of a predetermined length that is inclined at a predetermined upward slope toward the track starting end 16a with respect to the bowl bottom surface 14. A W tangling release gate 17 is formed, and two drop gates 1 are provided in the middle of the track 16, that is, at a position away from the tangling release gate 17.
8 is formed.

As shown in FIG. 6, the two-piece drop gate 18 is constructed by making the width narrower than the normal track 16, and its width is almost the same as the diameter of the wire material used to form the C-clip W. This is to separate the C-clips W, which are transported in layers, into one piece.

Further, in a portion located in front of the two-piece drop gate 18, as shown in FIG. is provided. This air blow gate 19 has a nozzle 19a that blows out air as shown in FIG.
The air jetted from this nozzle 19a is directed in a direction that causes the C-clip W to roll along the track 16 in the transport direction. In addition, C that receives rolling force due to air blow
- The notch Wa of the clip W is the nozzle 19a.
Only those corresponding to

A C-clip W drop gate 20 is formed near the end of the track 16. As shown in FIG. 8, this gate 20 consists of a hole 20a bored in the side wall of the bowl 14 and having a diameter larger than the outer diameter of the C-clip W.
One end of a chute 21 that guides the clip W in a predetermined posture to an assembly machine (not shown) or the like is arranged concentrically. The chute 21 has a notch so that only the C-clip W that is transferred with the notch Wa in contact with the track 16 can be picked up.
The chute 21 is formed from a bar member having a protrusion 21a that engages with the chute 21, and one end surface of the chute 21 is aligned with the inner wall surface of the bowl 14.

In the vibrating feeder having the component feeding mechanism configured as described above, if the electromagnet 15 is directly excited with the power frequency while the C-clip W is inserted into the bowl 14, the bowl 12 supported by the leaf spring 12 is torsionally vibrated, and as a result, the C-clip W on the bowl bottom surface 14a is moved in the direction of torsional vibration (in the direction of arrow A in FIG. It is transferred on the table 17a in an upward and inclined direction,
The C-clip W, which has reached the upper end of the slope, falls onto the bowl bottom surface 14 again. This separates the intertwined C-clips W one by one.

On the other hand, as the bowl 14 undergoes torsional vibration, the C-clips W are successively transported on the track 16 from its starting end 16a in the direction of arrow B in FIG. 3. When the two-clip drop gate 18 is reached, the C-clips on the upper layer side of the C-clips W, which are being transferred in an overlapping manner, are dropped, and only one C-clip is allowed to pass through. As a result, the C-clips W are lined up one by one on the track 16 after the gate 18.

Further, when the C-clip W being transferred in the direction of arrow B on the track 16 reaches the attitude correction air blow gate 19, the notch Wa is transferred toward the nozzle 19a as shown in FIG. 7, for example. For the C-clip W, by blowing air from the nozzle 19a into the inside of the C-clip W from the notch Wa, the C-clip W is rolled in the direction of the arrow in FIG. 7, and its posture is changed. is corrected as shown by the two-dot chain line. This becomes the C-clip with the desired normal orientation and orientation. Further, the C-clip W, which is transferred in the attitude shown by the two-dot chain line in FIG. 6, passes through as it is.

Then, when the C-clip W that has passed through the air blow gate 19 for correction reaches the full-form dropping gate 20, only the C-clip W in the attitude corresponding to the full-form dropping gate 20 falls from the gate 20 into the chute 21. However, the other C-clips W are returned into the bowl 14 from the terminal end 16b of the track 16.

In this embodiment as described above, since the entanglement release gate 17 is provided, the entangled C
- The clips can be separated and the alignment efficiency of the C-clips on the track 16 can be improved. Also, the C-
By blowing air into the clip W through the notch Wa, the C-clip W is made to roll and its posture can be corrected to the desired direction.
The number of aligned and supplied C-clips W in a posture where Wa is in contact with the track 16 increases, and the aligned and supplied rate can be improved. Therefore, even if the automatic parts sorting device and the assembly machine are directly connected, there will be no shortage of C-clips supplied to the assembly machine. Furthermore, since the C-clips can be automatically fed out of the feeder through the drop-off gate 20, automatic filling of C-clips into a magazine or automatic feeding to an assembly machine can be easily performed.

In the above embodiment, the alignment transfer of C-clips has been described, but the present invention is not limited to this, and can be applied to any ring-shaped parts having a notch, such as a C-shaped concentric retaining ring as defined by JIS. Furthermore, the parts feeding method of this invention is applicable not only to bowl-type vibrating feeders but also to linear feeders.

Effects of the Invention As explained above, in the vibrating feeder of the present invention, a detanglement gate consisting of a jump table of a predetermined length inclined at a predetermined upward slope in the direction of movement of the parts is provided in the component movement path of the component storage container where the feed vibrates. As a result, the intertwined ring-shaped parts fall from the top of the jump table onto the parts moving path and collide with each other, allowing the intertwined ring-shaped parts to be separated. In addition to improving the alignment efficiency of the ring-shaped parts, since the truck is equipped with an air blow gate for posture correction, the direction of the ring-shaped parts whose notches face the air blow can be corrected to the desired posture. Accordingly, it is possible to improve the alignment supply rate of ring parts in desired postures. In addition, a total drop gate is installed at the end of the track to take out only the ring-shaped parts that match the silhouette of the part in a predetermined posture out of the container. In addition to being able to sort out and eliminate parts such as C-clips whose orientation is difficult to determine, the present invention has the effect of reliably and efficiently sorting, aligning and supplying parts such as C-clips.
