Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorting device suitable for sorting fruits and vegetables that tend to have cavities inside.

BACKGROUND ART Sorting devices for fruits and the like include weight sorting devices that sort objects by weight and shape sorting devices that sort objects by external shape, and both are used depending on the type of objects to be sorted and the purpose of sorting. At the actual sorting site.

Generally, multiple sorting lines are installed in parallel for each grade of the material to be sorted, and the material to be sorted is first graded based on its appearance and then fed to the corresponding sorting line. It has become. Among the sorting devices that make up the sorting line, weight sorters generally have higher sorting accuracy than shape sorters, and are widely used for sorting tomatoes and mandarin oranges that tend to have uneven shapes. It was not possible to extract abnormal products that were large in shape relative to their weight, such as those with holes inside.

If an abnormal product with a large shape relative to its weight is mixed with one rank lower in grade and one rank higher in weight category (class), it will be passed as a passed product. In the sorting line using
It would be extremely advantageous if this could be used as a grade one rank lower.

In view of the above-mentioned circumstances, the present invention has been made with the purpose of providing a sorting device that can reduce abnormal products that are large in shape relative to their weight by one grade and make effective use of them. , a weight sorting line is provided for each grade of the material to be sorted, and the weight 17 (weight 17) (the material to be sorted taken out from the said takeout "1" is placed in the takeout Ll provided for each Ichikawa classification of the sorting line). A shape sorting device was installed to inspect whether the product had an appropriate external shape for the set weight and remove abnormal products, and a conveyor was also installed to mix the abnormal products extracted by this shape selection device with products one grade lower. Hereinafter, the embodiment shown in the drawings will be described.

Figure 1 shows an example of the sorting device according to the present invention.
This is a two-sided view, in which a chevron-shaped sorting plate 2 with a high center is provided at the front of the hopper 1, and a weight sorting device 3 is installed in front of the plate 2.
