Description

{APPARATUS FOR SORTING FRUIT}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fruit sorting apparatus, and more particularly, to a fruit sorting apparatus capable of sorting fruits discharged continuously by a transfer conveyor according to a set weight at a plurality of gates, .

Generally, various types of fruits on the market are priced based on quality such as shape, size, taste and sugar content of each mountain, but some fruits such as grapes are formed according to their weight There is also.

For the fruits of which the price range is formed by weight as described above, the fruits harvested from the fruits of the fruits must be graded by weight before packing.

Conventionally, a conveyor-type weight sorting apparatus has been disclosed as a sorting apparatus for fruits which are packed and circulated selectively sorted by weight.

According to the above-mentioned conveyor type weight screening apparatus, when the surface of the fruit is hard, the fruit is placed on the upper surface of the conveyor and the surface is not damaged during the separation process to the outside, However, fruits such as grapes, which have a weak surface, are disadvantageous in that they are scratched or flawed in the screening operation, which makes it difficult to maintain quality.

Therefore, in the prior art, sorting work by the weight of weak fruits such as grapes has been carried out by manual sorting method in which one piece is sorted one by one in the harvested state, and the weight is confirmed and separated into a sorting container according to a certain grade.

However, this conventional manual sorting method is preferable for maintaining the quality of the fruit because the surface of the fruit is hardly damaged unless the operator neglects it. However, since the harvested fruit is put one by one on the balance and the weight is confirmed, There is a problem in that not only the weight error is large when sorting the fruits but also the processing amount is limited so that only a small amount of fruits per unit time can be selected. A small selection of fruit means a decrease in workability and productivity, which leads to problems in that a large number of workers are required to be secured and that the profitability of fruit producers and sellers is inferior due to an increase in labor costs for sorting.

Accordingly, research and development on a fruit sorting apparatus capable of selectively sorting fruits, which are selected by an operator and transported continuously by a conveying conveyor after being placed in a conveying container, according to a set weight at a plurality of gates, It is a fact that is demanded.
