The position of the waterproof plug P in the trough 71 is aligned with the position of the waterproof plug P at the discharge end of the holding rail 54 of the torsional vibration parts feeder 2 on the upstream side.

Returning to FIG. 4, an overflow sensor 79 composed of a light emitting element 79a and a light receiving element 79b is attached to an upstream portion of the trough 71, and monitors a waterproof plug P transferred in the trough 71. When the waterproof plug P has been transferred normally, the light emitting element 79a to the light receiving element 7a
Although the light reaching 9b is interrupted by the waterproof plug P, if the interruption continues for a predetermined number of seconds or more, the controller 7 connected to the overflow sensor 79 determines that the transfer is clogged, and twists the upstream side. The vibration parts feeder 2 is stopped. In addition, when the interval not interrupted continues for a predetermined number of seconds or more, it is determined that the transfer is about to be short, and the vibration frequency of the torsional vibration parts feeder 2 is increased to increase the supply amount of the waterproof plug P.

The component feeder 1 according to the first embodiment is configured as described above. Next, its operation will be described. 3 and 4, a large number of waterproof plugs P are accommodated in the bowl 21 of the torsional vibrating parts feeder 2, and the driving unit 1
An alternating current is applied to the first coil 15 to apply clockwise torsional vibration to the bowl 21, and an alternating current is applied to the coils 65 and 65 ′ of the driving units 61 and 61 ′ of the linear vibrating parts feeder 3 to apply a trough 71. Is given a linear vibration in the direction of arrow n, and the overflow sensor 79 is also in the operating state.

In the bowl 21 of the torsional vibration parts feeder 2, the waterproof plug P accommodated in the reclined position is moved to the peripheral portion on the bottom surface 22 by the torsional vibration and is also moved in the direction shown by the arrow m. Get on the flat truck 24,
With the top surface T or the bottom surface B at the top, it is spirally raised in contact with the side wall 23. The waterproof plug P moves from the downstream end of the flat truck 24 to the lead-out track 25 and is guided to the outer peripheral side of the bowl 21, but at this time, a height at which only one of the waterproof plugs P can pass through the transfer surface of the lead-out truck 25. The stacked waterproof plugs P are broken by the wipers 26 provided at the bottom and are spread to the inner peripheral side of the lead-out truck 25.

Subsequently, the waterproof plug P is transferred from the lead-out track 25 to the narrowed alignment track 27, and the waterproof plug P being transferred on the inner peripheral side is transferred by falling down to the lower pocket 59. The amount is adjusted. Subsequently, the waterproof plug P transferred with the alignment track 27 in contact with the side wall 28 is
As shown in FIG. 5, FIG. 6, and FIG.
As shown in FIG. 8, which is a cross-sectional view of the vicinity of the upstream portion, the track block 30 provided through the step 29 downward from the downstream end of the alignment track 27 falls onto the sorting track 34, and the bottom surface B faces downward. Or an inverted posture with the top surface T facing down. When there is a waterproof plug P that rebounds when dropped, the waterproof plug P is provided on the guide plate 3 provided on the inner peripheral side in parallel with the upstream portion of the track block 30.
1 returns to the sorting track 34. In addition, there is a case in which the robot rolls over and assumes a lying posture.

Of the waterproof plugs P falling to the sorting truck 34, the waterproof plugs P that stand upright on the sorting truck 34 are fitted with the lower half H into a cut groove 37 formed on the side wall 35 so as to have two upper and lower stages. Protrusions 36a and 36b are inserted into the recesses,
Further, the tube portion E is transferred in contact with the side wall 35. At this time, the waterproof plug P also receives a component of the transfer force due to the torsional vibration to the outside of the bowl 21 and is pressed toward the side wall 35 and the cut groove 37 to be stably held and transferred.

The waterproof plug P in the inverted posture cuts the lower half H and the groove 3
7, and the waterproof plug P in the lying position is similarly transferred without fitting the lower half H into the groove 37 to reach the narrow portion 34b in which the width of the sorting truck 34 is reduced. However, as shown in FIG. 9A, a waterproof plug P in a normal upright posture is provided.
9 passes through the sorting truck 34 as it is,
The waterproof plug P ₃ of the inverted position shown by the one-dot chain line in B falls to the inner circumferential side losing the support of the top surface T is the narrow portion 34b, is transported at a top surface T on narrow portion 34b The waterproof plug P _{4 in the} inverted posture indicated by the two-dot chain line is prevented from being transported by the lower half H, which is on the upper side, coming into contact with the stopper 38T, and is similarly dropped downward and eliminated. Also be dropped into the waterproof plug P ₅ even inner circumferential side losing support by the narrow width portion 34b of the recumbent position shown in three-dot chain line exclusion.

Then, as shown in FIGS. 5, 6, and 7,
Also, as shown in FIG. 10 which is a cross-sectional view of the downstream portion of the sorting truck 34, the waterproof plug P in the upright posture selected extends from immediately downstream of the stopper 38 T so as to overlap with the downstream portion of the truck block 30. The upstream end of the inner peripheral side plate 54a of the holding rail 54 on the downstream side and the cut groove 3
7 and is stably transported by being pinched by the ridges 36a.

Subsequently, as shown in FIGS. 5 and 6 and FIG. 11 which is a sectional view of the holding rail 54, the waterproof plug P is provided with an inner peripheral plate 54a of the holding rail 54 and a ridge in the cut groove 37. 12a, and is transported to the discharge end of the holding rail 54 by being pinched by the outer peripheral side plate 54b provided to be connected to 36a, further twisted and leveled as shown in FIG.
The operation is shifted to the linear vibration parts feeder 3 on the downstream side.

As shown in the sectional views of FIGS. 13 and 14 in the trough 71 of the linear vibrating parts feeder 3, the waterproof plug P is provided with a guide plate 74 in the upper concave portion of the lower half H on the left side in the transfer direction. On the right side, the shoulder portion of the lower half H is held down by the guide plate 76 on the right side, and further, the upper end of the tube portion E is guided by the tip portion 75 s inside the holding block 75 and transported.

That is, when the waterproof plug P is subjected to a force that tilts forward or backward in the trough 71, the guide plates 74 and 76 are at different heights, so that they do not easily become a fulcrum of rotation. Even if one of them, for example, the guide plate 74 acts as a fulcrum of rotation, the other guide plate 76 acts to prevent the rotation.

Further, since the inner end portion 75s of the holding block 75 guides the upper portion of the tube portion E of the waterproof plug P, the movement of the upper portion is restricted, and accordingly the bottom surface of the lower convex portion F is correspondingly adjusted. Since the freedom of movement of B decreases,
The waterproof plug P is hard to fall down. Therefore, trough 71
The transfer is performed smoothly without causing the transfer to be clogged.

In the meantime, for example, in the case where the transfer clogging occurs in the trough 71 due to the delivery between the next step, the waterproof plug P is connected to the light emitting element 79a of the overflow sensor 79 installed in the trough 71. Since the light reaching the light receiving element 79b is blocked for a predetermined number of seconds or more, the controller 7 to which the overflow sensor 79 is connected stops the torsional vibration parts feeder 2. Then, when the transfer jam is eliminated, the torsional vibration parts feeder 2 is restarted.

If the transfer is in a normal state, it is determined that the transfer is in a normal state. If the interruption is continued for a predetermined number of seconds or more, the controller 107 connected to the overflow sensor 79 sets the waterproof plug P to the overflow state. Judging that it has occurred, the torsional vibration parts feeder 1 on the upstream side
02 is stopped to stop the supply of the waterproof plug P. If the interval not interrupted continues for a predetermined number of seconds or more, it is determined that the transfer is about to be short, and the vibration frequency of the torsional vibrating parts feeder 2 is increased to increase the supply amount of the waterproof plug P.

The cross-sectional structure of the trough 171 is the same as that of the embodiment, except that a waiting place 178 for the waterproof plug P is provided on the downstream side of the trough 171 and the aligned parts P are picked up by the robot R in the next process. Since the configuration is exactly the same as that of the first trough 71, the description thereof is omitted.

The component feeding device 101 according to the second embodiment is configured as described above. Next, the operation of the device will be described. In addition,

After passing through 3, the robot falls on the sorting truck 141 in an upright posture or an inverted posture.

In the sorting truck 141, the waterproof plug P in the upright position or the inverted position is transferred while being prevented from jumping out by the guide rail 147, and the waterproof plug P in the inverted position is first removed. 18 and 19, the waterproof plug P is transferred while being pushed toward the side wall 145 by receiving the component of the transfer force due to the torsional vibration toward the outside of the bowl 121,
The waterproof plug P in the upright posture shown by the solid line is
Since the lower half H is fitted between the transfer bottom 6 and the transfer bottom surface 149, the center of gravity is transferred without coming off the transfer bottom surface 149. Since the waterproof plug P lying down also fits in the lower half H, the exclusion hole 152 is formed.
Pass as it is. On the other hand, the waterproof plug P in the inverted posture shown by the one-dot chain line is pushed out toward the exclusion hole 152 without fitting the lower half H below the guide plate 146, and the center of gravity is removed from the transfer surface 149, so that the exclusion hole is formed. It falls from 152 and is eliminated.

In the following exclusion hole 154, FIGS.
In FIG. 1, the waterproof plug P in the reclined posture shown by the dashed line
When the center of gravity deviates at 9, it falls down from the exclusion hole 154 and is eliminated. After the exclusion hole 154, only the waterproof plug P in the upright posture is transported by supporting the concave portion from both sides by the guide plates 146 and 153 as shown in FIG.
Is transferred to the trough 171 of the first embodiment.
Similarly, the waterproof plug P is smoothly transferred without falling down.

Although the embodiments have been described above, the present invention is, of course, not limited to these, and various modifications can be made based on the technical concept of the present invention.

For example, in each embodiment, as shown in FIGS. 13 and 14, two troughs F formed in the lower half H of the waterproof plug P are provided on the trough 171 of the linear vibration parts feeder. A guide plate 74 inserted into the upper side of the concave portion, a guide plate 76 for holding down the shoulder of the lower half H from the opposite side, and a holding block for guiding the upper side of the tube E of the upper half of the waterproof plug P. The waterproof plug P is supported by the tip portion 75 s of the first 75.
Referring to FIG. 23 which is a sectional view similar to FIG. 3, and FIG. 24 which is a sectional view taken along the line [24]-[24] in FIG. 23, one of the waterproof plugs P transferred in contact with the transfer surface 189. The guide plate 184 is inserted into the upper concave portion formed by the convex portion F on the side, the guide plate 188 is inserted into the lower concave portion on the other side, and the shoulder of the lower half H is guided by the guide plate 186. The trough 181 may be supported so as to be suppressed. That is, the guide plate 1
84 is fixed to the trough block 182 by bolts 183b together with the holding block 183.
The guide plate 86 and the guide plate 188 are fixed to the trough block 182 with bolts 185b together with the holding block 185 with the block 177 interposed therebetween. That is, instead of supporting the waterproof plug P from both sides at the same height level,
They support at different height levels. In addition, a tip portion 185 s in which the inside of the holding block 185 is tapered is guided above the tube portion E of the waterproof plug P for transfer.

That is, when the waterproof plug P is subjected to a force that tilts forward or backward in the trough 181, it becomes a fulcrum of rotation because the guide plates 184, 186, and 188 exist at different heights. Even if one of them, for example, the guide plate 184 acts as a fulcrum of rotation, the other guide plates 186, 188 work to prevent the rotation. In addition, the inner end portion 185s of the holding block 185 guides the upper portion of the tube portion E of the waterproof plug P, so that the movement of the upper portion is restricted, and accordingly the movement of the bottom surface B of the lower convex portion F. Therefore, the waterproof plug P is hard to fall down. Therefore, the waterproof plug P is smoothly transferred without falling down in the trough 181 and causing a transfer clogging.

In each of the embodiments, the position of the waterproof plug P is selected by the torsional vibration parts feeder 2 or 102. As shown in FIG. 25, the selecting track 234 for selecting the position of the waterproof plug P is used. May be attached to the upstream end of the linear vibration parts feeder 203. Since the selection track 234 and each of its constituent elements are similar to the selection track 34 in the first embodiment, the selection track 34
The elements corresponding to the above-mentioned elements are denoted by the same reference numerals in the 200's and their description is omitted. The waterproof plug P is, for example, a flat track 227 of the torsional vibration parts feeder on the upstream side.
From the step 229 to be supplied. Then, only the waterproof plug P in the upright posture which is not removed from the sorting truck 234 is moved to the holding rail 254, twisted and leveled, and transferred to the downstream side.

In each of the embodiments, the outer edge has a circular shape.
Although a cylindrical waterproof plug P having a plurality of flange-shaped convex portions F has been exemplified as a transfer target, it is needless to say that the parts feeding device of the present invention can be applied to other similarly shaped parts. For example, there is a plastic insulator having a shape similar to the waterproof plug P, and a double nail is also included. Further, the flange-shaped projection may have a hexagonal or octagonal outer edge, for example. Furthermore, the waterproof plug may be a hollow cylindrical shape instead of a cylindrical shape, and the transfer target may be a solid cylindrical shape or a prismatic shape with a solid inside.
