Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for transporting a large number of stored fastener parts such as screws, rivets, pins, etc., each consisting of a head and a leg, to a predetermined position.

Conventionally, as a sorting device of this type, there is a conveying and feeding device for birch wood with faces described in Japanese Utility Model Application Publication No. 52-5938 as shown in FIG.

In this device, the face-shaped pine wood can be fed with the correct posture, but the storage chamber 53 for storing the face-faced pine wood and the conveyance path body 51 are fixed together, and both are fixed to the vibrating parts feeder 55. And these are made to vibrate as one. Therefore, the vibrating parts feeder 55 has to be made large, which not only increases the size of the device, but also increases the vibration amplitude when the vibratory parts feeder 55 becomes large, making it difficult to finely adjust this. This results in drawbacks such as difficulty in stably supplying birch trees with faces onto the conveying path body 51. In addition, when the amplitude of the birch with heads on the shunting road body 51 becomes large, the birch with faces jumps, so a holding plate is required above the shunting road body 51.
Therefore, due to the slight influence of this holding plate, the headed equipment may become jammed between the conveyance path body 51 and this holding plate, resulting in disadvantages such as feeding errors. The present invention is aimed at eliminating the above-mentioned drawbacks, and embodiments will be described below with reference to the drawings.

1 to 3, a base plate 1 of a fastener component sorting device has a frame 2 having an arcuate surface 10a fixed upright at one end thereof. A hopper 13 is provided at the upper part of the frame 2 so as to cover a part of the arcuate surface 10a.
is fixed, and a large number of screws 14 are stored in this hopper 13. A scoop plate 15, which will be described later, is arranged in the middle of this hopper 13 so as to pass through it.
At this position, the scoop plate 15 is configured to be able to swing up and down. Further, a rotary drive source A is fixed to the frame 2, and the power of the rotary drive source A is transmitted to the pulley 4 via the belt 3.

Further, a bearing plate 5 is fixed to the upper part of the frame 2, and a main shaft 6 is rotatably held in the bearing plate 5. The plate 4 is fixed to one end of the main shaft 6, and a disc cam 9 is fixed to the other end. This disc cam 9 has a guide roller 7 that is rotatable around a roller shaft 8, and has a cam surface on its outer periphery. On the other hand, "the arm 1 is attached to the support plate 10"
2 is attached to be swingable about a support shaft 11, and this arm 12 has a guide groove 12 extending in its length direction.
It has a. The guide roller 7 is fitted into the guide groove 12a, and as the disc cam 9 rotates, the guide roller 7 is configured to be able to reciprocate within the guide groove 12a. A scoop plate 15 is fixed to the arm 12, and a groove 15a is formed in the scoop plate 15.
The leg portion of the screw 14 is configured to be loosely inserted.

Further, this scoop plate 15 is formed in a fan shape, and the inner circumferential surface of the scoop plate 15 corresponds to the arcuate surface 10 of the support plate 10.
It is configured to spread along the line a. On the other hand, the outer circumferential surface of the scoop plate 15 is configured to slide on a sliding surface 16a of the partition plate 16 located in the middle of the hopper 13, and this scoop plate 15 is connected to a guide plate fixed to the support plate 10. It is configured to be positioned while being guided by the plate 17. On the other hand, a linear vibration unit B is fixed to the upper part of the frame 2, which is formed of a vibration plate 21 that vibrates slightly from a solenoid 20', and plates and counterfeit plates 22 that support both ends of the vibration plate 21.

A chute rail 18 is horizontally fixed to the upper part of this linear vibration unit B via a chute rail mounting base 19, and this chute rail 18 is attached to the support plate lo.
They are placed with a slight gap between them. Moreover, this chute rail 18 has a groove 1 having a width that allows the leg of the screw 14 to hang down.
8a, and one end of this chute rail 18 projects into the hopper 13, and is configured to receive the screw 14 scooped up by the scoop plate 15 and allow it to flow down on the chute rail 18. In front of this chute rail 18, a separation supply unit C is located fixed to a unit fixing base 23 with a slight gap.
It is configured to separate the screws 14 on the chute rail 18 one by one and feed them to an automatic screw tightening machine (not shown). Further, a misaligned parts removing means is disposed directly above the chute rail 18, and this misaligned parts removing means has a removing plate 25, which removes misaligned screws 14 from the chute rail 18. configured to prevent intrusion.

The exclusion plate 26 is rotatably attached to a guide block 26 about a pin 27, and the guide block 26 is attached to a lever 29 that swings about a support shaft 30.
Due to the action of the chute rail 18, the chute rail 18 is horizontally moved so as to move in parallel. A cam roller 28 is rotatably attached to the tip of the lever 29, and the cam roller 28 is configured to be biased by a spring 31 so as to roll along the cam surface of the disk cam 9. ing. A pin of a blocking member 32 is arranged at the end of the support plate 10 inside the hopper 13, and is configured to prevent the head of the screw 14 from being caught in the gap between the supporting plate 10 and the chute rail 18. There is.

In the above-mentioned fastener parts sorting device, the rotational drive source A
is activated, and the disc cam 9 rotates together with the pulley 4. Along with this, the guide roller 7 rotates and moves along the guide groove 12a formed in the arm 12. Therefore, the arm 12 swings, and the scoop plate 15 swings within the hopper 13. The screw 14 is scooped up by the swinging of the scoop plate 15, and the screw 14 reaches the top of the chute rail 18. At this time, as the arm 12 swings, the lever 29
Since the guide block 26 also swings, the removal plate 2
5 reciprocates along the chute rail 18, and the screws 14 that are misaligned on the chute rail 18 are dropped into the hopper 13.

Also, "when the scoop plate 15 rises, the screws 14 of the scoop plate 15 fall, and the chute rail 15 and the support plate 1
0, but because the pin of the blocking member 32 is located, the screw 14 is not caught in this gap.
It falls into hopper 13. On the other hand, chute rail 1
8 is vibrated by the linear vibration unit B, the screw 14 on the chute rail 18 moves forward and reaches the separation supply unit C at its tip, and is supplied from this separation supply unit C to a predetermined position. As explained above, the present invention scoops up screws with a scoop plate that swings within the hopper 13, supplies them to a chute rail arranged horizontally, and vibrates only this chute rail with a linear vibration unit. At the same time, a predetermined gap is provided between the support plate on the fixed side to which the hopper is attached and the chute rail, and a blocking member is arranged on the support plate to prevent parts from entering this gap. Therefore, the linear vibration unit only needs to be small, and the amplitude of the vibration is also small, making it possible to finely adjust the amplitude.Not only does it move forward smoothly, but the parts do not jump around, so there is no need to hold the head down. It is possible to reduce supply errors.

Further, in the present invention, since the blocking part is arranged between the support plate and the chute rail, the head of the part,
Washers incorporated in parts are not pinched, and
There are advantages such as being able to operate the chute rail continuously and providing a highly reliable device.
