A yoke 12 straddling both conveyors is provided above the conveyor 1, and an adsorption transfer means 13 is mounted on the yoke 12 so as to reciprocate by an intermittent drive type geared motor and a crankshaft. The suction transfer means 13 has five suction cups 14 connected to a vacuum source (not shown) at an interval corresponding to the interval of the guide rails 10 for each guide rail 10 (5 blocks × 4 rows = 20 blocks for 2 blocks). Forty push pieces in total) are provided at a predetermined pitch, and four pushers 15 for stopping each slip conveyor 8 are provided for each slip conveyor 8. When the suction cup 14 is located on the slip conveyor 8, the suction cup 14 is lowered by the air cylinder 16 so that the suction cup 14 is operated and raised by the air cylinder 16. When the suction cup rises, it moves onto the belt conveyor 11 by the geared motor 17 and the crankshaft 18, and the suction state of the suction cup is released. This operation is reciprocated simultaneously. Also, the air cylinder can be lowered immediately before the suction cup is opened. The belt conveyor 11, which is arranged so as to be sandwiched between the slip conveyors 8a and 8b and runs in parallel, uses a motor 19 as a drive source, a sheave S, guide rollers R1, R2, R3,
R4, R5, R6 and guide plates G1 and G2 guide and orbit. The beam sensor 20, the light source 21 and the light source C from the position downstream of the belt conveyor 11 and away from the suction transfer means.
The CD camera 22 and the thickness detection sensor 23 are sequentially installed. In particular, the light source 21 and the CCD camera 22 pass the light from the light source 21 through the slit 24 of the conveyor belt formed by the guide rollers R5 and R6 and the guide plates G1 and G2, and the image of the beans is CCD. The camera 22 was set to capture. The beam sensor 2
0, the CCD camera 22 and the thickness detection sensor 23 are installed, and air nozzles 25a, 25b, 25c, and
Are connected to a compressed air source (not shown), and compressed air is ejected by the signals of the sensors 20, 23 and the CCD camera 22 to sort beans. Reference numeral 26 shown in FIG. 1 is a return conveyor in which beans transferred from the slip conveyor 8 but not transferred by the adsorption transfer means 13 are collected by the hopper 27 and sent back to the original stockyard. . Also, 28 in the figure is a bean (C rank product) whose warp is detected by the beam sensor 20.
Is a conveyor for transferring the beans to a discharge basket of beans sorted into C rank by a CCD camera. Next, the transfer / sorting operation in this embodiment will be described. The beans stacked in the stockyard 4 gradually move in the downstream direction due to the vibration of the vibration table 3, are divided by the flow dividing plate 5, and are then separated by the partition plate 6.
Slide into the vibrating grooved rail 7 partitioned by. The beans that have slipped into the vibrating grooved rail 7 are aligned in the longitudinal direction and move forward, and then fall onto the slip conveyor 8 that is continuously provided so as to partially overlap the end of the vibrating grooved rail 7. The beans that have fallen onto the slip conveyor 8 are transported to the downstream direction by riding on the slip conveyor 8. However, the direction of the beans may change due to the vibration during the fall. Slip conveyor 8 to match the traveling direction of the conveyor
The beans that have been realigned while passing through the guide plate 9 provided on the surface of the
It is guided into the guide rail 10 which is slidably arranged on the surface of, and is sequentially transferred in the downstream direction to reach below the adsorption transfer means 13. When the beans reach the bottom of the suction transfer means 13, the suction transfer means 13 that reciprocates by the geared motor 17 and the crankshaft 18 causes the slip conveyors 8a and 8b.
It is transferred to the belt conveyor 11, which runs in parallel so as to be sandwiched between the two. The operation of the suction transfer means 13 will be described in more detail. When the suction transfer means comes onto the slip conveyor 8, the air cylinder 16 works and the suction cup 14 descends to suck the beans. Next, the air cylinder 16 works on the ascending side and the suction cup 14
As the beans rise, the beans are lifted and transferred onto the belt conveyor 11 by the crankshaft 18, where the suction of the suction cup is released and dropped onto the belt conveyor 11. At this time, the regulation plate 29 so that the direction of the beans does not change
Is provided, the beans that are transferred do not jump and are placed on the belt conveyor 11 at regular intervals and transferred to the sorting zone. The suction transfer means that dropped the beans onto the belt conveyor 11 moves as it is and moves onto the slip conveyor 8 on the opposite side, and repeats the same operation as described above alternately. The beans placed on the belt conveyor 11 first pass through the beam sensor 20. At this time, if the beans are warped, the beam is blocked, and the signal causes the air nozzle 25a to operate, and the air is ejected to the C class hopper, and those without warping pass safely. Next, the light passes through the light source 21 provided below the slit of the belt conveyor 11 and the CCD camera 22 provided above it. The image of the beans captured by the CCD camera 22 is compared and compared with a pre-stored limit sample, and the bean thickness detection sensor 23 determines whether or not the passing beans are overmature, and these are integrated. By judging, the good products are discharged to the A class hopper by the air nozzle 25b, the 25c air squirrel to the B class hopper, and the C class products to the C class hopper. The curled beans detected by the beam sensor 20 are discharged as C class, transferred by the conveyor 28, and collected in the C class hopper at the end of the belt conveyor 11. Also, the beans that have not been applied to the adsorption transfer means 13 by the slip conveyor 8 and are discharged are returned to the stock yard 4 by the return conveyor 26.

EFFECTS OF THE INVENTION As is clear from the above description, the beans can be transferred and supplied to the sorter with a certain distance between the beans and the beans can be reliably sorted.
