Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a sorting apparatus, and more particularly, to a method of combining and discharging articles such as fruits and vegetables sorted from a plurality of sorting conveyors into the same working unit. It relates to a sorting device that can be used.

[Conventional technology]

Conventionally, for example, as a typical sorter for sorting fruits and vegetables, as shown in FIG. 15, a sorting conveyor of a type of sorting and discharging to the side of the transport path by grade during the transport of fruits and vegetables is required for each grade. There are several sorting devices installed side by side.

Since the grade ratio of fruits and vegetables differs according to the kind of fruits and vegetables, crop pattern, harvest time, etc., the conventional sorting device is
The required number of sorting conveyors are arranged according to the grade ratio. The sorting apparatus shown in FIG. 15 shows a five-row type as an example, but designates the first and fifth rows as excellent, the second and fourth rows as excellent, and the third row as good.

In this way, when the sorting conveyor is multi-row, the reach of the fruit picker who supplies the fruits and vegetables is from the near side to about the third order, and the same fruit picker cannot supply the whole fruit. For this reason, the selectors are arranged on both sides of the sorting device, for example, the selector on the left side in the traveling direction is in charge of the first to third articles, and the selector on the right side is in charge of the supply of the third to fifth articles. To do. The fruits and vegetables supplied in this manner are measured and inspected by the measuring unit, and then sorted by class in the sorting and discharging unit for each row.

The sorted and discharged fruits and vegetables are stored in bins and the like provided on the side of the sorting conveyor according to grade and grade, and are packed in a box.

[Problems to be solved by the invention]

However, according to the conventional sorting apparatus, the fruit sorter (grade judging person) responsible for the first to third articles is different from the fruit sorter responsible for the third to fifth articles, and the fruits and vegetables supplied to each article are different from each other. Since each product is sorted and discharged from each sorting outlet, each product has the disadvantage that the products discharged to the left and packed into the box and the products discharged to the right and packed into the box lack the uniformity of the grade, even in the same sorting category. Was.

Furthermore, since the same sorting section is separately stored at different positions (left or right), it is necessary to separately arrange storage devices, packing devices, materials, and the like. It is uneconomical to separately use pooling equipment and personnel at sorting outlets that have low rates and are only sparsely discharged because of equipment costs and operating efficiency.

Also, since fruits and vegetables in the same sorting section are divided and discharged on the left and right sides, the amount discharged at each position is reduced, and an automatic box packing device cannot be introduced.

The problem to be solved by the present invention is that, by using a plurality of sorting conveyors, those having the same sorting section are combined and discharged to the same place, thereby improving the uniformity of the quality, increasing the operation efficiency of the facility, and freeing up. It is to improve the packing efficiency by performing a proper packing arrangement.

[Means for solving the problem]

In order to solve the above-mentioned problem, a sorting device of the present invention includes a sorting conveyor that transports articles by placing the articles on a sorting / discharging section in the middle of a transport path and discharges the articles to a side of the transport path according to a predetermined sorting category. A sorting device having a plurality of sorting conveyors, wherein the sorting and discharging sections of at least two sorting conveyors among the plurality of sorting conveyors each have an outlet for the same sorted and sorted product, and are arranged at predetermined intervals in the vertical direction. And the outlets of the same sorting and sorting products are arranged vertically.

As the articles, fruits and vegetables are used, and particularly, soft fruits which are easily damaged are placed on a tray so as not to be rolled and conveyed, and a sorting conveyor is configured so that the tray with the fruits and vegetables is sorted and discharged to the side of the transport path.

The sorting conveyor of each strip has a measuring means for measuring and inspecting the articles on the upstream side of the sorting and discharging section in the middle of the transport path. This measuring method is used when fruits and vegetables are selected.
There are two types of fruits and vegetables: one is configured to measure a class determination element of a size such as a shape dimension or weight, and the other is configured to measure together a class determination element such as this class determination element and an external surface condition. It is configured appropriately according to.

At least two sorting conveyors arranged side by side at predetermined intervals in the vertical direction are provided with discharge / joining means adjacent to the outlets of the same sorting and sorting products, respectively, so that the articles are added to the same boxed portion. I do. As the carrying-out merging means, for example, a carrying-out device such as a driven belt conveyor, a roller conveyor, or a slide is used, and a storage device such as a roller conveyor capable of accumulating is provided adjacent to the end of the carrying-out device. , So that the articles of the same sorting section are combined together.

Further, the plurality of sorting conveyors are configured using a conveyor chain or the like that can be bent horizontally and vertically so as to run and rotate in a curved shape in the horizontal and vertical directions. The plurality of sorting conveyors rotating in a curved shape are arranged side by side at the same height in the supply section on the upstream side of the sorting and discharging section, and as proceeding from this section, the discharge ports of the same sorted and sorted products are arranged. The sorting conveyors are arranged side by side at predetermined intervals in the vertical direction.

Further, the plurality of sorting conveyors include a feeding section, a curved section,
Different conveyors may be connected for each part such as an inclined part and a straight running part.

[Action]

According to the sorting device of the present invention configured as described above, the articles placed on the plurality of sorting conveyors are measured for their size and the like by the measuring means during the transportation, and the measurement signal is output. You. In the sorting and discharging unit that discharges articles based on this measurement signal, sorting conveyors having outlets for the same sorting and sorting products are arranged side by side with the outlets corresponding to the upper and lower sides, and are conveyed up and down to be the same. The articles in the sorting section are discharged from the upper and lower discharge ports in the same direction, and act so as to be accommodated in the same box packing portion. In this way, articles in the same sorting section can be easily added to the boxed portion at the same location even if they are ejected from different different sorting conveyors, because they are ejected positions corresponding vertically. That is, the articles of the same sorting section discharged from the sorting conveyor of each strip are discharged in total, so that the quality variation of each strip is made uniform. In addition, the sorted and classified products, which have a low distribution rate and are sparsely discharged, can be stored in a predetermined amount by discharging them together, thereby increasing the mechanical efficiency.
