[0003]

However, if the supply timing of the sequentially supplied to-be-sorted objects does not coincide with the passing timing of the receiving recess of the assorting disc, the to-be-sorted object of the assorting disc is surely delivered. Is not accepted. Therefore, when performing high-speed sorting by increasing the rotation speed of the sorting disc, it is necessary to control the rotation speed of the sorting disc and the feed timing of the objects to be sorted with high accuracy, which complicates the device configuration. There are problems such as being expensive and expensive. The present invention has been made to solve the above problems, and it is an object of the present invention to provide a sorting disk that enables high-speed sorting by improving the shape of the receiving recess.

In order to achieve the above object, a disc for sorting according to the present invention as set forth in claim 1 is a receiving concave portion for receiving the to-be-sorted objects sequentially supplied by the shooters arranged close to the upper surface. Are formed on a predetermined circumference at equal angular intervals, and receiving step portions which are continuous with the respective receiving concave portions along the circumference and are shallower than the receiving concave portions are formed on the front side in the rotational direction, respectively. It is characterized by

According to a second aspect of the present invention, in the disc for sorting according to the first aspect of the present invention, the receiving concave portion and the receiving stepped portion are formed by cutting from the outer circumference, and a circumferential wall is provided along the outer circumference. It is characterized in that a plurality of openable and closable gates are provided on the circumferential wall so that the object to be sorted is discharged from the receiving concave portion by centrifugal force due to rotation.

[0006]

According to the disc for sorting according to the above-mentioned claim 1, the to-be-sorted objects sequentially supplied by the shooters arranged close to the upper surface are moved to the front of the receiving recess by the rotation of the disc for sorting. While falling to the receiving step portion which comes to the lower surface of the shooter, a part thereof remains in the shooter, and then falls into the receiving recess when the positions of the shooter and the receiving recess match. Therefore, in order to perform high-speed sorting, it is not necessary to control the rotation speed of the sorting disc and the timing of supplying the objects to be sorted with high accuracy, and it is not necessary to receive the objects to be sorted into the receiving recesses. Since the high-speed sorting can be performed only by improving it, the sorting device can be manufactured at low cost.

According to the sorting disc of the second aspect, the receiving recess and the receiving step are formed by cutting from the outer periphery. Then, a plurality of gates that can be opened and closed are provided on the circumferential wall provided along the outer circumference, and the plurality of gates are opened and closed at a predetermined timing, whereby the objects to be sorted are discharged from the receiving recess by the centrifugal force due to the rotation of the sorting disc. Sort. Therefore, there is an effect that it is possible to reliably and automatically perform high-speed sorting of the objects to be sorted received in the receiving recess.

EXAMPLE One example of the disc for sorting according to the present invention will be described with reference to a mode used for a discriminating / sorting device 1 for discriminating and sorting the quality of a golf ball b. The discriminating and sorting apparatus 1 shown in FIG. 1 has a sorting disc 4 which is horizontally rotated by a motor 3 arranged on a base 2.
It has. The lower end of the shooter 5 which sequentially supplies the golf balls b to be sorted at a predetermined timing is arranged close to the upper surface of the sorting disc 4. Eight recesses 6 for receiving the golf balls b, which are provided by cutting from the outer circumference, are formed in the sorting disc 4 at equiangular intervals. A receiving step portion 7 that is continuous with the receiving concave portion 6 toward the front side in the rotation direction and is shallower than the receiving concave portion 6 is formed.

When any one of the receiving recesses 6 corresponds to the lower side of the shooter 5 by the rotation, the receiving recesses 6 are made to correspond to the receiving recesses 6 adjacent to the receiving recess 6 on the front side in the rotation direction.
An image pickup camera 8 incorporating an image pickup element is provided. Also,
From the receiving plate 9 arranged on the lower surface of the sorting disc 4, an outer peripheral wall 10 surrounding the outer periphery of the sorting disc 4 is provided, and the outer peripheral wall 10 discharges the golf ball b received in the receiving concave portion 6. 11 and 12 are arranged. Gate 1
Numerals 1 and 12 are obtained by removing the outer peripheral wall 10 and then openably and closably closed by arcuate gate pieces 13 and 14 whose one end is axially supported.

It is controlled based on the signal of the photo sensor 20 intercepted by the eight interrupters 19 which rotate in synchronization with the sorting disc 4 on the lower surface of the.

According to the sorting disc 4 described above, FIG.
As shown in (a) to (d), the golf ball b falling from the shooter 5 is received by the receiving step portion 7 of the rotating sorting disc 4 in a state in which the upper half of the golf ball b remains in the shooter 5. When the receiving recess 6 comes to the lower surface of the shooter 5 due to the rotation of the sorting disc 4, the golf ball b falls from the receiving step 7 and is received in the receiving recess 6. Therefore, when the sorting disc 4 is rotated at a high speed to perform high-speed sorting, the golf ball b can be reliably received in the receiving recess 6 even if the supply timing of the golf ball b and the passage timing of the receiving recess 6 do not exactly match. To be

The discriminating / sorting apparatus 1 having the above-described structure is provided with a shooter 5
The golf balls b, which are supplied one by one at a predetermined supply timing and are dropped, are received in the receiving recesses 6 of the sorting disc 4, and based on the video signal picked up by the image pickup camera 8, the golf balls b are picked up by a control board (not shown). The process of determining the quality of is performed. The pass / fail judgment process for the golf ball b is
Whether or not the golf ball b can be used is checked by checking whether the golf ball b is deformed, frayed, worn or damaged. When it is determined that the golf ball b cannot be used based on each determination signal, the gate piece 13 of the gate 11 is opened and closed to release the golf ball b, which is determined to be unusable, from the receiving recess 6 by the centrifugal force caused by the rotation. , Collect by collecting gutter and sort automatically.
