Description

[Detailed description of the invention] [Industrial application field] This invention relates to a fruit sorting conveyor for sorting fruits such as apples, pears, peaches, and tomatoes, as well as vegetables.

[Prior art] A supply conveyor is installed on the side of a multi-row alignment conveyor that arranges and transfers the sorted fruits of multiple types, and an operator sorts the fruits being transferred on the supply conveyor by type. There is a type of sorting conveyor that feeds the fruit to the sorting conveyor. As a conventional technology of this fruit sorting conveyor, for example,
There is one published in No. 156277.

In this conventional technology, although a supply conveyor is provided on the side of the alignment conveyor, the fruits conveyed to the end of the supply conveyor fall downward, and the fruits are conveyed from the end of the supply conveyor. A conveyance device for conveying the fruit to the starting end side is not provided.

[Problems to be solved by the invention] In such a conventional device, when a large amount of fruit is supplied to the supply conveyor, the operator cannot finish the sorting work in time, and the fruit is removed from the conveyance end side of the supply conveyor. There were also problems in that the fruits would sometimes fall, and that if the sorting was attempted to be done quickly, the sorting would be sloppy.

Therefore, this invention aims to eliminate the drawbacks of conventional devices and reduce the burden on sorting workers by transporting the fruit sent to the end of the supply conveyor to the start end of the supply conveyor again. It is.

[Means for Solving the Problem] A technical means for solving this technical problem is to provide a plurality of sorted fruits of a plurality of types to be arranged and transferred to the transfer terminal side of the conveyor 11 that transfers the fruits. A row sorting conveyor 1, 2,... is provided, and a worker sorts the fruits to be transferred by type on the side of the sorting conveyor 1, 2,... and supplies the fruits to the sorting conveyor 1, 2,... A conveyor 5 is provided below the supply conveyor 5.
A return conveyor 6 is provided which takes over the remaining fruits from above and returns them to the starting end side of the supply conveyor 5, and the return supply position from the return conveyor 6 to the supply conveyor 5 is set to the upper side of the transfer position than the supply position from the conveyor 11. The fruit sorting conveyor has a structure in which a worker table 7 on which a sorting worker stands is provided on the outside of the return conveyor 6.

[Operations and effects of the invention] While the fruit being transferred on the supply conveyor 5 is sorted by a worker standing on the worker stand 7, each sorted fruit is sorted by sorting type on the front alignment conveyor 1,
2,...If you move it up, each alignment conveyor 1, 2,...
The fruits on the top are arranged and transferred by type, and the remaining fruits transferred to the terminal end on the supply conveyor 5 are transferred on the return conveyor 6 on the lower side, and are transferred to the starting end of the supply conveyor 5. They are then returned to the department and undergo sorting again in the same transport process as described above. Therefore, even if a large amount of fruit is temporarily supplied onto the supply conveyor 5 and the sorting operation cannot be completed in time, and some residual fruit remains, the fruit is fed back onto the supply conveyor 5 by the return conveyor 6, so that the fallen fruits are not removed. No need to pick it up
Workers can perform sorting work at their own pace.

Since the supply conveyor 5 and the return conveyor 6 are vertically provided, the distance between the worker platform 7 and the alignment conveyors 1, 2, . A standing worker can easily feed the fruit on the supply conveyor 5 to the arranging conveyors 1, 2, etc., and for this reason, a large number of arranging conveyors 1, 2, . . . can be provided. .

In addition, when returning and supplying the remaining fruits from the return conveyor 6 to the supply conveyor 5, the return supply device from the return conveyor 6 to the supply conveyor 5 should be placed at a position higher than the supply position from the conveyor 11 that newly supplies fruit. Since it is on the upper side of the transfer, the returned fruit is fed from below to the supply conveyor 5 with priority, and the returned fruit is not disturbed by the fruit newly supplied from the conveyor 11, and the returned fruit is fed downward. This prevents the fruit from falling and allows for a good supply of returned fruit.

[Example] Hereinafter, an example of this invention shown in the drawings will be described.
