Description

本願発明は、各種果菜をサイズ別、形状別、糖度別など規格（等階級）別に選別するための自動選別装置に関するものであり、特にトマト、桃、梨、茄子、メロン、小玉西瓜などの果菜の選別に適したものである。 The present invention relates to an automatic sorting device for sorting various fruit vegetables according to standards (equal class) such as size, shape, sugar content, etc. Especially fruit vegetables such as tomatoes, peaches, pears, eggplants, melons, and Kodamanishi. It is suitable for sorting.

トマトなどの果菜を選別する装置として、図７に示すものがある。これはチェーン（無端搬送帯）１に多数の果菜キャリア２が連結されており、各キャリア２の上面が可倒式の受皿となり、果菜３をこの受皿の上においてキャリア２に供給すると、搬送途中に計測部で等階級が判別され、その判別信号に基づいて、所定の仕分け用の果菜引受け体（ベルトコンベアやテーブル）４のところで受皿が横転され、果菜３が転がりながら果菜引受け体４上にプールされ、仕分けされるというものである。 As an apparatus for selecting fruit vegetables such as tomatoes, there is an apparatus shown in FIG. This is because a large number of fruit vegetable carriers 2 are connected to a chain (endless conveyance belt) 1, and the upper surface of each carrier 2 becomes a collapsible saucer. In the measuring section, the equal class is discriminated, and on the basis of the discrimination signal, the tray is rolled over at a predetermined sorter fruit acceptor (belt conveyor or table) 4 and the fruit vegetables 3 roll on the fruit acceptor 4. It is pooled and sorted.

図７の選別装置では、走行中の果菜キャリア２から受皿を横転させて果菜３を排出するために、第１に、受皿横転倒時の落下と転がりで果菜３が痛み、第２に、果菜引受け体４が果菜キャリア２の進行方向に対して真横に引出すもの或いは単なるテーブルであるために、果菜キャリア２の進行方向への運動が急に規制されて、果菜３は果菜引受け体４上を斜め横方向に勢い良く転がって進むこととなり、さらなる傷みの発生を生じさせる。果菜３がトマトの場合、熟す前の青くかたい状態で出荷することも多いため、この選果機も広く使われてきたが、しかしながら傷みを問題視する場合には、高価で維持コストの高いパン方式の選果機を選択するしかなかった。 In the sorting apparatus shown in FIG. 7, in order to cause the saucer to roll over from the running vegetable carrier 2 and to discharge the fruit vegetables 3, firstly, the fruit vegetable 3 hurts due to the fall and rolling when the saucer rolls over, and secondly, the fruit vegetables. Since the accepting body 4 is a table that is pulled out sideways with respect to the advancing direction of the fruit vegetable carrier 2 or is merely a table, the movement in the advancing direction of the fruit vegetable carrier 2 is suddenly restricted, and the fruit vegetable 3 moves on the fruit vegetable accepting body 4. It rolls in a slanting lateral direction and causes further damage. When fruit vegetables 3 are tomatoes, they are often shipped in a blue and hard state before ripening, so this fruit selection machine has also been widely used. However, when considering damage as a problem, it is expensive and expensive to maintain. There was no choice but to select a bread type fruit sorting machine.
