【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 5 shows the small parts A being aligned. The small part A is a rectangular parallelepiped, and has a vertical length a, a horizontal length b, and a height c of about several mm, and the dimensions of each part are a> b> c.

As shown in FIGS. 1 and 2, a plurality of alignment grooves 3 extending in the radial direction are formed at equal angles on the upper surface of a table 2 which is rotated in one direction by a motor 1. The groove width of the alignment groove 3 is slightly longer than the lateral length b of the small part A, and the groove depth is slightly deeper than the height C of the small part A.

An alignment brush 4 and an elimination brush 5 are provided on the table 2 at a required interval in the rotation direction of the table 2. The brushes 4 and 5 have elasticity and extend long in the radial direction of the table 2.

The tip portion of the alignment brush 4 is pressed against the table 2 and is vibrated by the vibrating device 6 in a direction orthogonal to the length direction. On the other hand, the expulsion brush 5 is fixedly arranged, and its tip is lightly pressed against the upper surface of the table 2.

A component receiver 7 for receiving a small component A discharged from the table 2 by the action of the removing brush 5 is provided at a lower outer portion between the aligning brush 4 and the removing brush 5. The small parts A discharged into the parts receiver 7 are sent to the supply chute 9 by the operation of the parts circulation device 8. The tip of the supply chute 9 faces the table 2 behind the alignment brush 4, and the small component A is supplied onto the table 2.

A holding plate 10 is provided on the table 2 at a required distance from the removing brush 5. The holding plate 10 is fixedly arranged, and a required gap is provided between the upper surfaces of the table 2. A chute 11 for discharging the small parts A aligned in the alignment groove 3 is provided on the outer side of the holding plate 10. The table 2 is rotationally controlled so as to stop when the alignment grooves 3 are aligned with the discharging shoe 11.

A compressed air supply hose 12 is connected to an inner end portion of the holding plate 10, and the compressed air supplied to the supply hose 12 is supplied into the alignment groove 3 which coincides with the discharge chute 11. . Due to the supply of the compressed air, the small parts A inserted into the alignment groove 3 are discharged into the discharging chute 11.

In the middle of the discharging chute 11, the posture including the front and back of the small parts A fed into the discharging chute 11 is judged, and a normal product is returned to the downstream side of the discharging chute 11 and an abnormal product is returned. An attitude determination / elimination device 14 is provided for feeding from the chute 13 to the component receiver 7.

Now, when the small parts A are supplied from the supply chute 9 onto the table 2 rotating in the direction of the arrow in FIG. 1, the small parts A are conveyed in the circumferential direction together with the table 2.

When the small parts A are conveyed, the alignment brush 4 is vibrated in the conveying direction of the small parts A by the operation of the vibrating device 6, and when the small parts A are conveyed to the position of the alignment brush 4, the alignment brush 4 is arranged. When the brush 4 moves backward in the direction opposite to the conveying direction of the small component A, the aligning brush 4 pushes the small component A back. Further, when the alignment brush 4 moves forward, the small component A moves toward the alignment brush 4.

When the alignment groove 3 of the table 2 moves to the position of the alignment brush 4, it is set in a predetermined direction among the small parts A that are conveyed back in the circumferential direction while being pushed back by the alignment brush 4. The small part A enters the alignment groove 3.

At this time, the small parts A may be accommodated in the alignment groove 3 in a normal posture, and may be accommodated in a tilted state as shown in FIG. 4B.

When the alignment brush 4 that has passed through the alignment groove 3 moves forward in the rotation direction of the table 2 and passes through the alignment groove 3, the small component A that has not entered in the normal posture is the alignment brush. It is pushed by 4 and made a normal posture.

The small component A that is not oriented in a predetermined direction passes through the alignment groove 3. Of the small parts A that have passed through, the small parts A located below the alignment brush 4 are pushed toward the alignment groove 3 by the forward movement of the alignment brush 4, as shown in FIG. 4C. The small parts A oriented in a predetermined direction are stored in the alignment groove 3.

As described above, by vibrating the alignment brush 4 in the direction orthogonal to the length direction, the alignment brush 4 is placed in the alignment groove 3 as compared with the case where the alignment brush 4 is simply arranged on the table 2. The probability of aligning the small parts A increases, and the parts A can be aligned in the alignment groove 3 with a very high probability.

Small parts A on the table that have passed below the alignment brush 4 and small parts that are caught in the alignment groove 3 are discharged from the table 2 into the parts receiver 7 by the removing brush 5. The small parts A in the parts receiver 7 are supplied to the table 2 from the supply chute 9 by the operation of the parts circulation device 8.

The alignment groove 3 in which the small parts A are aligned moves in the circumferential direction of the table 2, and when the alignment groove 3 moves to the position of the discharge chute 11, the table 2 stops. At this time, compressed air is supplied from the supply hose 12 into the alignment groove 3, and the small component A in the alignment groove 3 is sent to the discharge chute 11.

The rotation position of the table 2 is controlled by a method of index-rotating the table 2 by the motor 1 or a method of providing a sensor for detecting the alignment groove 3 and controlling the motor 1 by the output from the sensor. Can be adopted.

The small parts A sent to the discharging chute 11 are conveyed forward as they are in a normal position by the operation of the attitude determination and elimination device 14, and the abnormal parts are returned from the returning chute 13 to the parts receiver 7. .

In the case of the embodiment, the table 2 is rotated, but a plurality of linear alignment grooves are formed on the upper surface of the table 2 and the table is orthogonal to the length direction of the alignment groove. You may make it move to a direction.
