In the sorting truck 34, the waterproof plug P, which is in the upright posture, is transferred while the lower half H is fitted into the cut groove 37 and the tube portion E contacts the side wall 35. At this time, the waterproof plug P is located on the sorting track 34 inclined downward toward the outside of the bowl 21, and the side wall 35 is cut by the component of the received torsional vibration force toward the outside of the bowl 21. Since it is pressed against the groove 37, it is stably transferred on the sorting track 34.

On the other hand, since the waterproof plug P, which is in an inverted posture in the sorting truck 34, cannot fit the lower half H into the cut groove 37, the sorting truck 34 is accordingly reduced.
The narrower portion 34b, which is narrower as shown by a dashed line, is formed in the middle part of the sorting truck 34, and the waterproof plug P in an inverted posture is formed. Since the center of gravity deviates from the narrow portion 34b, it falls to the inner peripheral side and is eliminated. In addition, the waterproof plug P in the reclined position also has the narrow width portion 34b.
At the same time, it falls to the inner peripheral side and is eliminated. In this manner, only the selected waterproof plugs P in the upright posture are discharged from the downstream end of the sorting truck 34.

Therefore, the corresponding elements are denoted by the same reference numerals with ('), and description thereof is omitted.

From the upstream flat track 27 ', the waterproof plug P is transported in contact with the side wall 28' in a reclined position with the top surface T or the bottom surface B at the top.
9 'is dropped and moved to the sorting track 34' formed on the track block 30 'in an upright or inverted posture. The waterproof plug P, which bounces when dropped, is returned to the sorting truck 34 'by the guide plate 31',
Some roll over.

The waterproof plug P in the upright position is provided with a cut groove 3 having ridges 36a 'and 36b' formed on a side wall 35 '.
7 ′ is transported by fitting the convex portion F into the sorting truck 3.
Even at the narrow portion 34b where the width of 4 'is reduced, the center of gravity is not removed, and it is transported without contacting the stopper 38T', and the downstream side extends and overlaps with the inner circumferential side of the sandwiching rail 54 '. The sheet is transported while being sandwiched between the plate 54a 'and the ridge 36a', and further supported at the downstream end of the sorting track 34 'by the outer peripheral plate 54b' connected to the ridge 36a 'instead of the ridge 36a'. As a result, the sheet is transferred to the holding rail 54 'on the downstream side, and is stably transferred to the discharge end without disturbing the posture. Note that FIG.
, The holding rail 54 'is twisted on the downstream side so that the waterproof plug P is in a horizontal position.

On the other hand, the waterproof plug P in the inverted position cannot move the convex portion F into the cut groove 37 'and is transferred by the inner circumference of the sorting truck 34'. The center of gravity is deviated at the narrow portion 34b 'and the projection F falls upward, or the projection F contacts the stopper 38T' and is prevented from being transported and falls downward.
The rolled-over waterproof plug P is also transported on the inner peripheral side of the sorting truck 34 'and falls down at the narrow portion 34b' to be eliminated. That is, the waterproof plug P, which was in the lying position at the upstream portion of the linear vibration parts feeder 3 ', is supplied to the downstream side in the upright position after the sorting truck 34'.

When the sorting truck 34 'is installed in the middle of the transfer path of the linear vibration parts feeder 3', the waterproof plug P which falls to the side is installed in parallel with the linear vibration parts feeder 3 'and in the opposite direction. It can be collected in the trough of another linear vibration parts feeder to be transferred and returned to the upstream side of the linear vibration parts feeder 3 '.

In the case of the linear vibrating parts feeder 3 ', the vibration for transferring the waterproof plug P is simple, but in the sorting truck 34' attached to the linear vibrating parts feeder 3 ', the twist of the first embodiment is used. Unlike the sorting truck 34 attached to the vibrating parts feeder 2, the force for pressing the waterproof plug P against the side wall 35 'and the cut groove 37' does not work. However, since the sorting track 34 'is inclined downward toward the side wall 35', the transfer does not become unstable.

Although the embodiments of the present invention 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 the first embodiment, the sorting track 3
4 to obtain a waterproof plug P in an upright posture or an inverted posture,
Although a step 29 as shown in FIG. 15A, that is, a step 29 slightly larger than the length from the center of gravity of the waterproof plug P to the top surface T or the bottom surface B is provided between the alignment track 27 and the sorting track 34, As shown in FIG. 15B, a step 29 ′ having a drop approximately equal to the length from the center of gravity to the top surface T or the bottom surface B may be used. If the head is made smaller than this, it becomes difficult for the waterproof plug P to take a standing posture. In addition, when the head is increased, the vehicle is likely to roll over at the time of falling and to be in the lying position. In addition, instead of the step 29, as shown in the vertical sectional view of FIG.
The waterproof plug P may be dropped by providing an arcuate pipe-shaped chute 33.

Further, in the embodiment, the cut groove 37 of the side wall 35 of the sorting truck 34 has two protrusions 36a, 36 corresponding to the two recesses in the lower half H of the waterproof plug P.
Although b is provided, only one ridge 36a may be used when the upright posture of the part to be transferred is stable. In addition, it is needless to say that when the component to be fed has a relatively large number of convex portions and the number of formed concave portions is large, it is not necessary to insert the ridges into all the concave portions.

In each embodiment, for example, the inner peripheral plate 54a and the outer peripheral plate 54b
Are constituted by one plate, respectively, but may be plural if necessary.

In the second embodiment, the sorting track 34 'and the side wall 35' are provided in the middle part of the linear vibration parts feeder 3 ', but as shown in the vertical sectional view of FIG.
The sorting track 34 "and its side wall 35" may be integrally provided at the upstream end of the trough block 72 "of the linear vibration parts feeder 3". The components of the sorting track 34 ″ corresponding to the components of the sorting track 34 according to the first embodiment are (″).
Although the same reference numerals are attached and their explanation is omitted,
The waterproof plug P is supplied from the alignment track 27 "in the torsional vibrating parts feeder on the upstream side through the step 29" and passes through the sorting truck 34 ", for example.
Is twisted in the middle of riding on the holding rail 54 ", leveled, and transferred to the downstream side.

The sorting truck constituting the present invention may be installed on a line where the robot supplies the waterproof plug P in an upright posture.

Further, in each of the embodiments, the cylindrical waterproof plug P having three flange-shaped convex portions F with a circular outer edge is taken as an object for arranging. It may be cylindrical, and the number of convex portions may be three or more or two. This can be dealt with by forming ridges in the cut grooves corresponding to the concave portions formed by the convex portions. In addition, the sorting truck and the side wall according to the present invention can be fed with plastic insulators or double nails having the same shape other than the waterproof plug P. In addition, the outer edge of the flange-shaped convex portion is a polygonal cylindrical or columnar component, or the outer peripheral surface is a rectangular cylindrical shape having a lower half portion in which the outer edge is formed with a plurality of circular or polygonal flange-shaped convex portions. Also, a prismatic part can be sorted into a part in an upright posture and a part in other postures by the sorting track and the side wall of the present invention.

[0056]

The present invention is embodied in the form described above, and has the following effects.

According to the component feeding device according to the first aspect, a cylindrical or cylindrical component or a coaxial component having a plurality of convex portions whose outer edges are formed in a circular or polygonal flange shape coaxially with the lower half of the side surface. In a component feeding device for transferring a prismatic or rectangular cylindrical component having a similar convex portion in an upright position, a component in an upright position fits a lower half of the component into a cut groove formed on a side wall of a sorting truck. Also, with the help of the ridges inserted into the recesses of the parts, the parts are stably held and transported without disturbing the posture, and the parts in the inverted posture and the parts in the recumbent posture can fit the lower half H into the cut grooves. It is transported away from the side wall by that much and removed by removing the center of gravity at the narrow part sandwiching the width of the sorting track, so that the number of parts supplied per hour in the upright posture to the next process is guaranteed at a high level I can do it.

According to the parts feeding device according to the second aspect, the parts which do not fall from the narrow portion of the sorting truck among the parts in the inverted posture and fall down by contacting the stopper and are eliminated, so that the sorting accuracy is improved. Further improve.

According to the component feeding device according to the third aspect, the components in the upright posture are immediately after the completion of the selection, one of the ridge in the cut groove and one of the holding rails extending from the downstream side on the selection track. As a result, the concave portion is pinched, and the component is directly transferred to the pinching rail on the downstream side. Therefore, the components do not disturb the posture after the sorting, and greatly contribute to the stable supply of the component.

According to the component feeder according to the fourth aspect, the probability that a component transferred from the flat plate truck on the upstream side in a lying position on the sorting truck becomes an upright position or an inverted position when falling down a step is high. In addition, the supply amount of components in the upright posture can be maintained at a high level.
