Description

TECHNICAL FIELD The present invention relates to a carry-out device for automatically sorting and selecting crops such as carrots and radishes. More specifically, the present invention relates to a carry-out device. A conveyor conveyer projecting locking projections for each, a bottom transport path for locking and transporting the crops along the bottom of the crop storage section, and a state in which one crop is placed on each of the locking projections in line with this In addition, the present invention relates to a crop unloading device that is arranged in a state having a lifting and transporting path for lifting and transporting the crops upward.

[Conventional technology]

In the above-mentioned crop unloading device, conventionally, as shown in FIG. 5, for example, the lifting transfer path (B) is located above the bottom transfer path (A) at the end of the transfer path (A) in the transfer direction. It was installed in a posture inclining toward.

[Problems to be Solved by the Invention] However, in the carrying-out device, each locking protrusion (1
2) One crop is not always placed and conveyed on top of each other, and two or more crops are erroneously placed and conveyed, and there is a problem that automatic sorting in the subsequent process cannot be performed accurately. there were.

It is an object of the present invention to solve the above-mentioned drawbacks and to provide a crop unloading device that can reliably carry out crops one by one.

[Means for solving the problem]

A characteristic configuration of the present invention is, in the crop unloading device described at the beginning, in the lifting conveyance path, the endless rotation band is formed in a state of being inclined backward from a vertical plane toward a conveyance start end side of the bottom conveyance path. In addition, a receiving portion having a protruding width capable of receiving and supporting only one crop is formed on the outer end side of each locking projection.

[Work]

Even when two or more locking projections are erroneously locked by the respective locking projections in the bottom transport path and transported, the transport path surface in the lifting transport path faces the downwardly-inclined lower side. The placed crops on the toes try to fall downward. However, only one crop is received and supported by the receiving portion formed on the locking projection and is conveyed to the conveying end portion.

〔The invention's effect〕

Therefore, it is possible to reliably prevent the next protrusion from being conveyed to the next process while two or more pieces are erroneously placed on the locking protrusions, and it is possible to accurately perform the automatic sorting operation and the like.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an automatic sorting device (2) for sequentially sorting and sorting long vegetables (a) such as carrots and radishes, which are an example of crops, from a hopper (1) that stores a large number of them in order. . This sorting device (2) is a unloading device (3) for unloading the long vegetables (a) from the hopper (1) as a single unit, and the long vegetables (a) supplied from the transport end portion of the unloading device (3) in a column. An aligning / conveying unit (4) that conveys the vegetables in an aligned state, and a measuring unit (5) that automatically measures the weight of the long vegetables (a) while conveying in line with the conveying end of the aligning and conveying unit (4). A sorting unit (7) for automatically sorting and collecting in a plurality of collecting units (6) for each weight rank based on the measurement result in 5).

The unloading device (3) is provided at the starting end of the aligning and conveying section (4).
There is provided a downflow guide portion (8) for changing the laterally-oriented long vegetable (a) dropped and supplied from the end portion of the vertical direction to the vertically-oriented posture. Further, as shown in FIGS. 3 and 4, the aligning and conveying section (4) includes a pair of left and right endless rotating belts (9),
(9) are arranged in parallel so as to face each other in a slanting posture, and guide plates (1
0) is provided. The automatic belts (9), (9) are arranged in parallel at a predetermined interval (L), and this interval (L) is set.
A long vegetable (a) having a smaller diameter than that is dropped downward, and a vegetable having a smaller diameter than a predetermined value is dropped and selected.

Next, the carry-out device (3) will be described. In the carrying-out device (3), locking projections (12) are projected on the outer peripheral surface of an endless rotation belt (11) as an endless rotation band at a predetermined pitch to form a conveyor (13). Lifting and transporting the transport conveyor upward along the bottom of the hopper (1) with the long vegetables (a) and the long vegetables (a) placed one by one on the locking projections (12) in a row. It is configured to be delivered in the state of having the transport path (B).

Then, as shown in FIG. 2, in the lifting conveyance path (B), a state in which the conveyance surface of the endless rotation belt (11) is inclined backward from the vertical plane toward the conveyance start end side of the bottom conveyance path. And a receiving portion having a protruding width capable of receiving and supporting only one crop is formed on the outer end side of each of the locking projections.

With this configuration, even if two or more pieces are mistakenly locked and carried by the locking projections (12) in the bottom transfer path (A), the lifting transfer path (B) is
Since only one piece is placed on each locking projection (12), the extra long vegetables (a) will drop downward, and the post-process measurement can be performed accurately. The transfer speed of the transfer conveyor (15) in the measuring section (5) is set to be higher than the transfer speed of the aligning transfer section (4) so that the weight can be accurately measured in a spaced state. There is.

[Another embodiment]

Instead of the endless rotation belt (11), a member forming a locking projection may be erected and connected at a predetermined pitch over a pair of left and right endless chains.

It should be noted that reference numerals are added to the claims for convenience of comparison with the drawings, but the present invention is not limited to the structures of the accompanying drawings by the entry.
