Description of the Related Art As means for sorting fruits such as melons and packing them in boxes, as disclosed in Japanese Utility Model Application Laid-Open No. 53-72887, a vertical direction provided on a cardboard box distribution conveyor is disclosed. There is a configuration in which a cardboard box take-out chute that is rotatable is provided. [0003] The above-mentioned means can be installed at a high position, so that a space in the vertical direction can be utilized, but an operator operates a foot pedal to take in an empty box. It is necessary and workability is poor. In addition, when the empty box to be taken out and the subsequent empty box are displaced from each other and the succeeding empty box that is not taken out gets on the cardboard box take-out chute, the empty box may be caught on the cardboard box distribution conveyor and cannot be taken out. When both adjacent empty boxes are strongly pushed, the cardboard box take-out chute may not be able to slide smoothly only by the rotating operation of the chute, resulting in a decrease in work efficiency. SUMMARY OF THE INVENTION The present invention is directed to a discharge-side boxing location 35 of draw-out conveyors 21 to 24 which are extracted from sorting conveyors 8 to 11 for each fruit sorted to a predetermined grade or grade.

One more melon can be placed on the rear side by the rear slopes 12b and 12b of the ridges 12 and 12 and the slope 14a of the ridge 14. It can be placed on individual parts and different grades can be placed with their positions shifted back and forth. For example, of the belt conveyors, the excellent melon is placed (designated position a) with the convex lines 13, 12, 12 of the conveyors 8, 11, and the convex lines 14, 12, 12.
With the setting, it is set so that the excellent melon is placed and transported (designated position b).
The configuration is such that non-defective melons are placed on designated portions 3, 12 and 12 (designated position c), and transported on the same level with the ridges 14, 12 and 12 (designated position d). [0010] The belt conveyor is provided with a mark member (in the illustrated example, a protrusion integrally formed with the belt conveyor) 15 for each set of ridges.
The configuration is such that it is shielded and hidden by the melons (excellent or good products) placed on 3, 12, and 12, and the grade can be confirmed based on the detection results of the following detectors 16, 16,... For each melon. That is, each detector 16 has 16a,
16b is provided with an optical detection unit,
The detection unit 16a operates by receiving a measurement signal each time the reference numeral 11 moves by one set of the convex main body (one pitch). The detecting unit 16a can detect the mark member 15 to the front designated position (excellent or good melon). The detection section 16b can detect the presence or absence of a melon at the rear designated position (excellent / average grade) [0011] The grade selection section 7 performs a first sorting which performs a grade-specific discharge from the left and right outer belt conveyors 8 and 11. And a second sorting section 7b for performing class-wise discharge from the inner belt conveyors 9 and 10 which are extended from the section 7a, and a shape detector 19 comprising light sources 17, 17 and a CCD camera 18 at the start end side. 19. Shape detectors 1 are provided.

The end side of each of the above-mentioned draw-out conveyors 21 to 24 is arranged at a box-packing position where an operator waits, receives a supply empty box, and packs it into a predetermined number for each class. … Is transferred. Empty boxes which are sequentially fed out from the mezzanine making machines 27, 27 on the mezzanine floor via the roller conveyer-type distribution conveyors 28, 28 are provided with guide chutes 29, 29,. Is supplied along with a tray 30, a net cover 31, or a fruit cap 32 as an auxiliary material. That is, belt conveyors 8 to 11
In the machine frames 33, 33, a passage 34 through which an operator can move is formed along the transfer direction of the belt conveyor, and the distribution conveyor 28 is provided in the machine frame 33 along the passage 34. The guide chutes 29, 29,... Are integrally formed in an inclined upper and lower two-stage configuration. The starting end of the guide chutes is viewed into the passage 34, and the discharge side is a box mounting portion as a packing place formed on the discharge side of the draw-out conveyors 21 to 24. Looking above 35, 35 ... Reference numerals 36, 36... Are mounting portions for mounting the sub-materials, and are configured as shelf frames projecting from the left and right sides of the machine frames 33, 33. Reference numerals 37, 37 are provided on the upper machine casing 38 for each of the guide chutes 29, 29,..., And are configured to be able to blink based on the operation of a detector (not shown) that detects the absence of an empty box on the guide chutes. Each of the draw-out conveyors 21 to 24 is provided with a detector 39, for example, a photoelectric sensor composed of a light-emitting and a photoreceptor, at the take-up start side thereof, and the detector 39 pays out one melon. The configuration is such that the presence or absence of a melon in the allowable start end side space s can be detected, and the drive motor 40 of the draw-out conveyor is intermittently turned ON and OFF.
When receiving the supply of the melon and stagnating at the starting end of the drawer conveyor, the motor 40 in the non-driven state is driven for a fixed time, and even if receiving the next melon supply to the starting end of the drawer conveyor, it is strongly against the front melon on the drawer conveyor surface. It is configured not to collide. Next, the operation will be described. The received melon is removed by a cleaning brush on the way of being conveyed by the vibrating conveyor 5 to remove dust adhering to the surface, and reaches the grade sorting section 6. In the grade sorting section 6, grades are evaluated for each melon by evaluators waiting on the left and right, and excellent and excellent products are placed on the belt conveyors 8 and 11, and good and average products are placed on the belt conveyors 9 and 10. At this time, one melon is placed on one set of the ridges, and the excellent or non-defective product is located at the front cup-shaped designated position formed by the ridges 13 and 12, and Are convex 14 and 12, 1
2, the evaluator places each melon on the belt conveyor while evaluating the grade according to this setting. Subsequent detectors 16 are provided for each of the conveyor strips, and simultaneously or temporally move a set of ridges from a certain side for the presence or absence of the mark member 15 and the melon at the specified position of the front and rear cups. In the belt conveyors 8 and 11, when only the melon is detected and the mark member 15 is not detected, the line controller 20 is determined to be excellent.
And when the melon and the mark member 15 are detected, it is determined to be non-defective. When only the mark member 15 is detected and no melon is detected, no melon is placed on any of the front and rear cup-shaped designated positions. On the other hand, in the belt conveyors 9 and 10, similarly, the other detectors 16 are used.
Then, any one of the non-defective product, the standard product, and the non-mounted state is determined, and is input to the line controller 20. The melons thus placed on the four belt conveyors 8 to 11 reach the starting end of the class sorting section 7 as they are. At the start end side, the outer shape is detected by the shape detectors 19, 19, and is input to the line controller 20 in the same manner as the above-mentioned grade determination input. Then, in the first sorting section 7a, excellent and excellent products are delivered to draw-out conveyors 21 and 24, each of which is set for each size, and in the second sorting section 7b, good and average products are drawn out for each of the draw-out conveyors 22. , 23. On the other hand, in the box making-empty box supply line,
The empty boxes produced are sequentially transported and supplied via the container conveyor 28, and the worker on the passage 34 transfers the empty boxes on the container conveyor 28 to the guide chute 29 as appropriate, and the predetermined drawers 21 to At the same time, the secondary material 30, 31 or 32 is taken out of the shelf frame 36 one by one at the branching point where the empty box is filled. In this way, the empty box is taken out from the guide chute 29 by the boxing worker waiting at the discharging side boxing place of the draw-out conveyors 21 to 24, and the set of auxiliary materials is prepared. The set number of melons will be boxed. In this way, since the auxiliary materials are supplied simultaneously with the empty boxes, the auxiliary materials can be reliably supplied for each empty box, and the auxiliary material storage area is secured separately near the boxing worker. There is no need to improve workability. The melon-packed products are carried out and transported outside the building via product carrying conveyors 26, 26.
