Reference numeral 14 denotes a measuring device for measuring the height of the parts 10 to be sorted, which is fixed at a position opposite to the measurement support part 12, and the part to be sorted held on the measurement support part 12 is directed toward "1 part" of the parts 10. The measuring rod 16 is installed so as to protrude.The protruding end surface of the measuring rod 16 comes into contact with the top of the parts 10 to be sorted, and the height of the parts 10 to be sorted is measured.

Reference numeral 18 denotes a component housing cylinder whose axis is vertically fixed directly below the measurement support section 12 . This component storage cylinder 18 is formed with an open upper end DL, and is formed in a size having an inner diameter sufficient to accommodate the components 10 to be sorted.

Reference numeral 20 denotes a guide pipe that is attached radially from the side surface of the component storage cylinder 18 diagonally downward. In this embodiment, in order to sort the parts 10 into five stages, five guide pipes 20 are provided at equal intervals on the outer surface of the parts storage cylinder 18. Note that the attachment portions of each guide pipe 20 to the component housing cylinder 18 are on the same horizontal plane. In addition, the parts storage cylinder 18
A through hole (exhaust port) having the same diameter as the inner diameter of the guide pipe 20 is provided at the attachment portion of the guide pipe 20, and the guide pipe 20 and the component storage cylinder 18 communicate with each other via the exhaust port. Note that the inner diameter of the guide pipe 20 is such that the parts 10 to be sorted inside the pipe are

A storage box (not shown) is installed to store the parts 10 that have passed through each guide pipe 20 to be sorted.

Reference numeral 24 denotes a rotating body inserted so as to be in sliding contact with the inner circumferential surface of the component housing cylinder 18. The rotary body 24 is formed into a cylindrical body in which the upper surface of the cylindrical body is cut obliquely at an angle of about 45° to the axis of the cylinder. That is, the rotating body 2
4 is formed into an inclined surface, and as shown in FIG.
The lower end edge of the inclined surface is set so as to smoothly connect to the discharge port 20a.

Next, the operation of the above embodiment will be explained. The sorting apparatus of this embodiment measures the height of the parts 10 to be sorted and sorts the parts into five categories based on the measurement results. That is, first, the parts to be sorted supplied from the parts feeder are moved to the full position by the stopper pin 13.
It is positioned on the fixed support part 12, and the height is measured by the measuring device 14. Based on this measurement result, the pulse motor 26 is moved lψ, and the rotating body 24 is rotated and positioned in a direction directly facing the guide pipe 20 according to the classification of the measurement result. Next, the part 10 to be sorted is placed on the stopper pin 1.

In this way, the parts to be sorted are sequentially sent to the measurement support section 12, and the parts to be sorted are automatically sorted based on the fll'J determination result of the parts 10.

In addition, a sensor is provided in the guide pipe 20 to confirm that the parts 10 to be sorted have passed through the guide pipe 20, so that the sorter should confirm each time that the parts 10 have passed through the guide pipe 20 before performing the next sorting operation. You may also do so. By doing this, sorting can be performed more reliably.

According to the device, the sorting in the second embodiment is simple because the parts to be sorted can be sorted by simply rotating the rotary body 24 to a predetermined position, and the mechanical action is simple. It has the feature that sorting can be done quickly by providing it to rotate in the opposite direction and rotating it in the most efficient direction of rotation.

In addition, in the embodiment mentioned above, a cylindrical body whose upper end was formed as an inclined surface was used as the rotary body 24, but as shown in FIG. It is also possible to use a rotary body 24a having a disc shape and connect the lower surface of the disc-shaped rotary body 24a to the pulse motor 26.

In addition, FIG. 4 shows another embodiment of the device for sorting the parts to be sorted, and in this example, the rotating body described above is not used.
A cylindrical rotating body 28 having an inclined inner bottom surface is used. In FIG. 4, reference numeral 30 denotes a discharge port which is provided through the wall surface at the lowest part of the sloping bottom.

In this example as well, the rotary body is rotated to a predetermined position by a pulse motor in the same manner as described above, and the parts to be sorted which have been stored in the rotary body 28 are set in advance by adjusting the rotational position of the output loco 30 at the beginning of the rotary body 28. By setting, it is possible to sort and discharge parts in a predetermined category at a predetermined position. Therefore, if a storage box or the like for storing the parts to be sorted is installed in accordance with this discharge position, the parts to be sorted can be sorted in the same manner as in the embodiment described above.

The present invention has been variously explained above using preferred embodiments, but the present invention is not limited to these embodiments.
Of course, many modifications can be made without departing from the spirit of the invention.

(Effects of the Invention) According to the device of the present invention, the parts to be sorted are reliably sorted by discharging the parts to different discharge ports or predetermined positions according to the classification of the parts, as shown in the double series. The parts to be sorted can be easily sorted by sliding them down an inclined surface. Further, since the parts are sorted by simply rotating the rotary body, the mechanical operation is simple and the parts can be sorted very simply and efficiently.
