DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for sorting long vegetables such as cucumbers.

[0002]

2. Description of the Related Art For example, a cucumber sorting apparatus requires a form capable of simultaneously processing different cargo ports.
As disclosed in Japanese Unexamined Patent Publication No. 2-38789, the starting positions of the inner two and outer two of the four sorting conveyors are shifted to solve the problem of the working posture of the grade evaluator beside the conveyor.

[0003]

However, there is no disclosure of a receiving conveyor for supplying to a sorting conveyor, and there is no consideration for a large number of consignments. Therefore, even if an attempt is made to apply the central two strips to the large-volume cargo outlet, it is necessary to move the received goods stored in the receiving container or the like to the vicinity of the sorting conveyor, which is still unnatural.

[0004]

SUMMARY OF THE INVENTION The present invention provides a sorting conveyor 5b, which has spaces 8, 9 occupied by class evaluators on the left and right sides of the receiving side of a receiving conveyor 2 for receiving sorted items such as long vegetables. 6a, the sorting conveyors 5b, 6a are located outside the sorting conveyors 5a, 6b so as to form a pair with the sorting conveyors 5b, 6a. A device for sorting long vegetables and the like will be provided.

[0005]

For the farmers with a large number of carry-in containers, the sorting conveyor 5b,
For a farmer with a standard line or less than a plurality of lines 6a, the outer sorting conveyor 5a or 6b paired with the sorting conveyors 5b and 6a is applied. In particular, when it is necessary to process a large amount, a grade evaluator can be positioned on the left and right of the end of one conveyer 2 and can be replaced on the sorting conveyors 5b and 6a immediately after, so that the work of the receiving process is smooth.

[0006]

An embodiment of the present invention will be described with reference to the drawings. The figure shows a sorting facility for long vegetables such as cucumbers.
Numeral 3 denotes a conveyer for receiving goods, in which a non-driving roller is rotatably provided. Of these, the trucks are sequentially shortened from the side close to the entrance 4 of the fruit sorting place, and a space for the entrance and exit of the trucks near each of the conveyors 1, 2, 3 is secured.

Between the end of the receiving conveyors 1 and 2 and between the end of the loading conveyors 2 and 3, respectively, the starting ends of a pair of left and right two-row type sorting devices 5 and 6 are placed in the occupied space 7 of the class evaluator. , 8, 9, and 10 are provided at intervals. The sorting devices 5 and 6 are each provided with two sorting conveyors 5a and 5b and 6a and 6
b, these sorting object placing portions are of a well-known saucer type, and are connected at right and left to a drive chain (not shown), and are discharged around a horizontal axis in relation to a guide rail (not shown). This is a configuration in which the object is turned over and dropped.

[0008] In addition, by displacing the mounting position on the receiving tray to the left and right in the transfer direction, it is possible to distinguish the grade judgment by the grade evaluator. The classifying devices 11, 11... Are provided in the sorting devices 5, 6, and the positional deviation information and the length detection information are input to the control unit 12. Based on the detection information, the control section 12 outputs discharge command signals to the cucumbers individually in the classifying sections 13, 13. The cucumber is dropped and discharged by falling down the tray in the corresponding classifying section, and is discharged to the receiving boxes 15, 15. It is to be noted that the side closer to the class judging units 11, 11,.
It is supposed to handle excellent products.

Reference numeral 16 denotes a container place for sorting and storing the sorted cucumbers collected in the receiving boxes 15, 15... In containers by class and class, and 17 denotes a relay conveyor provided in parallel with the non-drive type rollers. A first shrink wrapping device 18 is provided in parallel with the relay conveyor 17. The shrink packaging device 18 is a device for wrapping and packaging a predetermined number of cucumber or the like, for example, three at a time.

A belt conveyor 19 is connected to the end of the shrink wrapping device 18 in a direction perpendicular to the transfer direction. 19 parts of this conveyor are configured as a box packing section for performing a cardboard box packing process. This conveyor 19 is a product conveyor 2
0 and can be carried out to the product storage 22 near the entrance via the packing machine 21. The sorting device 4,
A second shrink wrapping device 23 is provided in parallel with the drawer 14 for handling L-excellent products near the transfer end portion side of No. 5. Since the packing device 23 has a large amount of sorting and collecting, it is specially provided corresponding to the draw-out conveyor 14. However, the packing device 23 and the product conveyor 20 are connected to each other. It is a box.

When the second shrink wrapping device 23 and the container place 16 are located close to each other and the handling amount of the L-excellent product is much less than the possible throughput of the shrink wrapping device 23, the container is taken out from the adjacent draw-out conveyor 14. For example, an LL product that is packed in a container, for example, may be interposed and processed. The second floor of the building is configured as a box making factory, and the empty cardboard boxes prepared in a predetermined shape by the box making machine 24 are slightly separated from the three parallel boxing conveyors 25, 25 ... and the direction is changed to L-shaped. It is sent to the conveyor 26 as appropriate, and the delivery conveyor 25,
The 25 ... side is disposed on a belt conveyor 19 connected to the first shrink wrapping device 18, and the other box conveyor 2
6 is looking into the boxed portion on the second shrink wrapping device 23 side.

In the drawing, reference numeral 27 denotes a conveyor for carrying an empty receiving container outside the building, and reference numeral 28 denotes a passage / material storage space formed in a space formed between the left and right sorting devices 4 and 5. The operation of the above example will be described. Cucumber-laden containers that are carried in by truck are sorted by cargo port and stacked in the cargo receiving area. That is, it is placed between each conveyer for receiving each cargo. At this time, the receiver of the receiver who receives the largest amount of cargo is put on standby at the center. Thus, the receiving containers placed on each of the receiving conveyors 1, 2, 3 are transferred to the sorting devices 5, 6 while being graded by a grade evaluator at the end of the receiving containers. Those using the conveyor 5a on the outside of the sorting device 5 and those on the conveyor 3 for receiving the goods use the conveyor 6b on the outside of the sorting device 6, respectively. Those from the receiving conveyor 2 having the largest receiving amount can be transferred to the sorting conveyors 5b and 6a from the left and right sides of the end. Therefore, it is possible to process and sort three different cargo outlets at a time. At the time of this transfer, the external appearance is visually judged and divided into excellent and excellent, and the mounting position on the tray is made different.

Then, the class determination units 11, 11...
The detection result of the class item such as the thickness is transmitted to the control unit 12 and, at the same time, the data for determining the mounting position on the tray is transmitted. The control unit 12 that has input these inputs the grade of the cucumbers.
The class is specified, and it is classified and discharged into the preset class and class. The cucumbers collected in the receiving boxes 15, 15,... Via the draw-out conveyors 14, 14,... Are packed in containers to be delivered as appropriate, and are once stacked in the container storage 16 for each class.

Next, the containers in the container place 16 are placed on the relay conveyor 17, and the loaded cucumbers may be supplied to the starting end side of the shrink wrapping device 18 so that the cucumber can be packaged three by three. The packaged products are packed in a cardboard box every about 10 kg on a belt conveyor 19 and transferred to a product conveyor 20. On the other hand, the drawer conveyor 14 at the final side end, which has a large amount of sorting and collecting, etc. (L excellent product), is transferred directly from the receiving box 15 to the second shrink wrapping device 23 and is packed and packed.

In the above embodiment, the conveyors 1, 2, 3,
Can be used to process three consignments at once.
Alternatively, any one of 6 or 6 may be configured as a single conveyor so that two loading ports can be processed, and the sorting apparatuses may be installed in three lines in order to provide a large capacity processing unit. When the second shrink wrapping device 23 and the container storage 16 are located close to each other and the handling amount of the L-excellent product is significantly lower than the possible processing amount of the shrink wrapping device 23, the container is taken out from the adjacent draw-out conveyor 14 and the container is taken out. For example, LL excellent products to be packed may be interposed and processed.
