A hopper that accommodates a large number of screws to be supplied to the automatic assembly line and a hopper track that supplies the screws in the hopper to the screw conveying unit are used. The hopper track has a guide portion on an upper portion thereof, and the guide portion engages with a groove into which a shaft portion of a screw can be inserted and a lower surface of a screw head with the shaft portion of the screw inserted in the groove. An engaging surface is formed to extend linearly, and a screw in a hopper is inserted into the groove in the guide portion, and a lower surface of the head of the screw engages with the engaging surface. It is placed in the combined state.
Then, when passing the screw from the hopper track to the screw conveying section, the hopper track is tilted so that one end in the longitudinal direction of the guide section is higher than the other end, and the screw conveying section is attached to the other end of the guide section. In this state, the screw is slid from its one end to the other end by its own weight.

る。Next, the operation will be described. When the hopper track 9 is swung from the lower limit point Y to the upper limit point X by the swing drive means 11 in a state where the cylinder 15 is contracted, one or more screws 3 in the hopper 5 are screwed into the hopper track. When the hopper track 9 reaches the upper limit location X in this state while being supported by the upper surface 903 of the hopper 9, the sensor 13 detects that fact, and the engagement of the pin 1117 with the cam groove 1107 causes the hopper to move. The track 9 is held at the upper limit location X for a predetermined time. The detection signal from the sensor 13 is the sequencer 1
7, the cylinder 15 is repeatedly expanded and contracted a plurality of times under the control of the sequencer 17 until the predetermined time elapses.
When 01 is extended, the pad 1503 comes into contact with the lower end of the hopper track 9, and the hopper track 9 is intermittently and repeatedly vibrated. Due to this vibration, even if dirt is attached to the upper surface 903, the inner wall of the groove 905, or the like, or if there is unevenness on the lower surface of the head portion 301 of the screw 3 such as a screw with a spring washer, the screw 3 is guided by the guide portion 902. It smoothly slides up, and by this slide, the screw 3 closest to the rear end 709 on the guide portion 902 is delivered to the screw conveying portion 7.

7, the piston rod 1501 is stopped.
Is in a contracted state, and thereafter, when the predetermined time elapses, the swing drive means 11 swings the hopper track 9 from the upper limit point X to the lower limit point Y, and the upper surface 903 of the hopper track 9 inside the hopper 5. The screw 3 is buried in the screw 3 to return to the original state, and thereafter, by repeating the above-described operation, the screw 3 is sequentially supplied from the hopper 5 to the screw conveying unit 7.

07 is exposed to the rear end 709 of the screw transport unit 7, and the front end 907
Is detected by the sensor 13 that the hopper truck 9 has reached the upper limit point X where the vehicle tilts so as to be lower than the rear end 911.
A sequencer 17 based on the detection signal from the sensor 13.
The cylinder 15 is expanded and contracted by the piston rod 1
The pad 1503 at the tip of 501 is brought into contact with the lower end of the hopper track 9 to give vibration to the hopper track 9. Therefore, the screw 3 is guided by the guide portion 902 without being affected by dirt attached to the upper surface 903, the inner wall of the groove 905, or the like, or the unevenness formed on the lower surface of the head 301 of the screw 3 like a screw with a spring washer. It can be smoothly slid above and reliably delivered to the screw transport unit 7.
Therefore, when supplying the screws 3 from the hopper 5 to the automatic screw tightening machine through the hopper track 9 and the screw conveying unit 7, it is possible to continuously supply the screw 3 to the automatic screw tightening machine, and to assemble the parts. It is possible to prevent the assembling work from being interrupted and shorten the tact time of the assembling process.

可能であることは言うまでもない。The means for vibrating the hopper track 9 is not limited to the cylinder 15, and an ultrasonic vibrator may be used. Alternatively, the swing drive means 11 may be provided with a cam mechanism for generating vibrations. May be configured to vibrate. Further, the place where vibration is applied to the hopper track 9 is not limited to the lower end of the hopper track 9 as in the embodiment, but any place such as applying vibration from the side surface 901 is possible. Further, the vibration applied to the hopper track 9 does not have to be the intermittent and repeated vibration as in the embodiment, and is arbitrary such as applying the vibration to the hopper track 9 only once. Then, in the embodiment, the case where it is applied to the screw supply device that automatically and sequentially supplies the screws to the automatic screw tightening machine in the automatic assembly line of the home electric appliances and the like has been described.
It goes without saying that the present invention is widely applicable to sliding a screw on a guide portion of a tilted guide member and delivering the screw to another guide member.

A first guide member having a guide portion whose surface is formed to extend linearly,
The second guide member facing the other end of the guide part is inclined by tilting one end of the guide part in the longitudinal direction higher than the other end and sliding the screw from one end of the guide part to the other end by its own weight. Since the first guide member is vibrated while the first guide member is tilted when delivering the screw, even if dirt is attached to the guide portion or the lower surface of the head of the screw is uneven. The screw can be smoothly slid on the guide portion, and the screw can be reliably delivered from the first guide member to the second guide member.
