A notch 7 is provided in the outermost peripheral portion of the component conveying surface 2, and the sorting and removing device 8 of FIG. 1 is installed at the location where the notch 7 is formed.

The selection / removal device 8 includes an exemplary gate 9, an openable / closable opening / closing bottom member 10 forming a bottom portion of the component carrying surface 2 at a place where the exemplary gate 9 is provided, and an opening / closing bottom member 10.
And an actuator 11 for opening and closing. The model gate 9 is attached to the lower surface of the base 12 with bolts or the like, and has a downward groove-shaped passage 9a, and its cross-sectional shape has a rectangular dimension and shape adapted to an appropriate dimension of the component 2. The cross-sectional shape of the passage 9a is formed gradually smaller toward the outlet side, and the side surface of the passage 9a on the ball outer diameter side is made to coincide with the peripheral wall surface 2b of the component conveying surface 2. In the present embodiment, the planar shape of the model gate 9 is such that the portion 9b (FIG. 3) forming the side surface of the passage 9a on the ball outer diameter side is projected more to the upper side in the component transport direction than the passage inlet. As in the fourth embodiment, the model gate 9A having a flat front surface may be used. The component 2 is an electronic component such as a chip capacitor in this embodiment. The base 12 is provided so as to extend in the radial direction of the ball 2, and the outer diameter side end is attached to the ball 2.

The opening / closing bottom member 10 is a chute that fits into a notch 7 formed in the component carrying surface 2 of the ball 1, and is vertically rotated via a spindle 14 to a bracket 13 on the lower surface of the base 12 at an intermediate portion. It is movably supported and is capable of descending and inclining to the outside in the radial direction of the ball 1. The opening / closing bottom member 10 has a thin-walled front end side portion 10a which is a part of the component conveying surface 2 so that a large inclination angle can be obtained without interfering with the bottom surface of the notch 7. Actuator 1
1 is a single-acting air cylinder in this embodiment,
It is installed downward on the base 12 via the mount 15.
The tip of the piston rod 11a of the actuator 11 is
A pin 17 is connected to an elongated hole 16 provided in the opening / closing bottom member 10. The actuator 11 may be a fluid pressure cylinder such as a hydraulic cylinder, or may be a solenoid or a motor.

As shown in FIG. 1A, the actuator 11 is connected to a fluid pressure source (not shown) such as an air source via an electromagnetic opening / closing valve 18 and a fluid passage 19.

The determination unit 20b is a unit that monitors the detection signal of the detector head 20a and determines the clogging, and is configured by a timer that outputs the clogging determination signal when the component detection output of the detector head 20a does not exist for a certain period of time. ing. The determination output of the determination means 20b is input to the opening / closing control means 21 and the vibration stopping means 22. The opening / closing control means 21 applies a drive voltage to the electromagnetic opening / closing valve 18 to apply the actuator 1
It is a means for driving 1. The vibration stopping means 22 is means for stopping the vibration drive unit 4 of FIG. Since the separating / removing device 8 is directly attached to the vibrating ball 1, the actuator 11 and the opening / closing bottom member 10 due to vibration are attached.
In order to prevent deterioration of the center of rotation of the device, it is preferable to provide a means (not shown) for applying an appropriate tension.

The operation of the above configuration will be described. The component W in the ball 1 is moved by the vibration of the ball 1 into a spiral component transport surface 2

The posture of the component W on the component transport surface 2 is adjusted during transport, and before the sorting / removing device 8 on the outermost periphery is transported, the component W is transported in a fixed posture along the peripheral wall surface 2b of the component transport surface 2. The proper part W is
It passes through the model gate 9 in the sorting and removing device 8 as it is, and is conveyed to the supply port 1a.

If the component W is a defective product such as a defective shape, a defective dimension, a defective surface treatment, a burr, etc., the component W is naturally clogged. The detector 20 constantly monitors the conveyance of the component 2 based on the output of the detector head 20a composed of a photoelectric sensor, and it is determined that the component W does not pass for a certain period of time.
When it is detected by b, the clogging determination output stops the vibration operation by the driving unit 4 of the vibrating component supply device via the vibration stopping unit 22 and causes the opening / closing control unit 21 to move the actuator 11 upward to open / close the opening / closing bottom unit. Tilt the material 10. Therefore, the defective part W clogged in the model gate 9 slides on the opening / closing bottom member 10 and is removed to the outside of the ball 1. After that, the oscillating operation of the drive unit 4 of the ball 1 is restarted by the automatic return means (not shown). The automatic resetting means is composed of a timer for detecting that a predetermined time has elapsed from the inclination of the opening / closing bottom member 10 or a detector (not shown) provided in the defective product removal path.

According to the sorting / removing device 8, defective products such as defective shapes and dimensions are naturally clogged and sorted, and the clogged products are quickly removed. Therefore, the number of supplies can be increased and the conveyance speed can be increased, the number of line stops of the connected machine can be reduced, and the production efficiency can be improved.
