is located on the back side of the component guide 21, and the bottom of the first stopper 30 faces the notches 26 and 28 of the component guide 21, and the stopper portion 40 of the second stopper 31 faces the notches 26 and 28 of the component guide 21. It is partially fitted into the notch 27 of the component guide 21, and is reciprocated in a direction across the component movement path of the component guide 21 as the piston rod 60 protrudes and retreats.

In this component supply device 1, when the piston rod 60 is retracted, the first stopper 30 is moved so that the stop portion 37 is retracted from the moving path of the cylindrical portion of the component A, as shown in FIGS. 4 and 5. In contrast, in the second stopper 31, the stop portion 41 protrudes into the guide groove 20. Therefore, the flange portion of the component A1 located at the lowest end contacts the stop portion 41 and is prevented from falling.

If the piston rod 60 protrudes in this state,
The slider 32 is moved via the connecting member 59 and the connecting body 55, and the first and second stoppers 30, 3
1 are moved together to the left in FIGS. 4, 5 and 7. As a result, the stop portion 37 of the first stopper 30 projects into the movement path of the cylindrical portion of the component A, and the stop portion 41 of the second stopper 31 retreats from the guide groove 20.

At this time, as shown in FIG. 7A, the first stopper 30 prevents the next part A2 from falling by the stop part 37 and pushes the cylindrical part of the part A1 downward by the inclined surface 38, so that the part A1 Even if parts A1 and A2 fall overlapping each other at the flange portion, the lowest part A1 is reliably separated from the next part A2.

When the piston rod 60 is fully extended, the seventh
As shown in FIG.
Completely retreat from 0. As a result, the component A1 located at the lowest end falls, and the next component A2 has its cylindrical portion contacting the stop portion 37 of the first stopper 30 and is prevented from falling.

Subsequently, when the piston rod 60 retreats, the first
and the second stoppers 30, 31 move in the opposite direction,
As a result, the stop part 37 of the first stopper 30 retreats from the moving path of the cylindrical part of the part A2, causing the part A2 to fall, but at this point, the stop part 41 of the second stopper 31 protrudes into the guide groove 20. Therefore, the flange portion of the component A2 comes into contact with the stop portion 41 and is prevented from falling.

As described above, this parts feeding device can feed parts one by one by simply reciprocating both the stoppers 30 and 31 together using the air cylinder 53.
By driving the parts in synchronization with the cylinder mechanism 9 for 1, the parts are moved in 1 in synchronization with the vertical movement of the punch 11.
Can be delivered one by one.

Effects of the Device As described above, the present invention provides first and second stoppers each having a stop portion on the upstream side, and the stop portion of the first stopper is located upstream of the stop portion of the second stopper. , and when the stopping part of one stopper protrudes into the parts moving path of the chute that guides the parts, the stopping part of the other stopper is set so as to retreat from the parts moving path, and furthermore, both stoppers are set so that both stopping parts are Since the parts are reciprocated together in the direction across the parts moving path, the stopping parts of both stoppers alternately protrude and retreat into the parts moving path, making it possible to reliably feed the parts one by one. By synchronizing the reciprocating motion with the reciprocating motion of the punch, parts can be fed one by one in synchronization with the movement of the punch. Further, since both stoppers are simply reciprocated as one unit, the drive mechanism and support mechanism for both stoppers are simple and inexpensive. Furthermore, since the inclined surface is formed on the tip side of the first stopper, it has practical effects such as being able to forcibly and reliably feed parts one by one along the inclined surface.
