Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an automatic crop sorting apparatus for automatically sorting and collecting long vegetables such as radish and carrots and other transported objects to be transported. Regarding

[Conventional technology]

In this sort of sorting apparatus, conventionally, there have been those in which automatic weighing of conveyed objects and grade sorting work for each weight rank are automatically performed. That is, while the object to be conveyed is placed on the conveyor belt and conveyed, the amount of flexure of the belt based on the weight is detected to measure the weight, and based on the measurement result, the material is conveyed from above the conveyor belt via the downflow chute. And collect the transported objects collected in the collection container by hand in a separate place and then pack them in a specified number or a specified total weight in a separate package. I was going to store it in a case.

[Problems to be Solved by the Invention]

However, in the above-mentioned conventional technique, the transfer work from the collection container to the packaging case is troublesome, which is one of the causes of a decrease in overall work efficiency, and automation of such work has been desired.

In addition, it is also desired to prevent the damage of the transported object due to the momentum when the down-shoot chute is made to flow down so that the automatically sorted products can be collected by the collection unit. It was

The present invention makes it possible to efficiently perform a distribution operation for each predetermined collection and supply amount of sorted objects to be sorted,
The purpose is to prevent damage such as damage to the objects to be sorted.

[Means for solving the problem]

The automatic crop sorting apparatus according to the present invention measures the weight of the transported object while transporting the transported objects stored in the hopper by the unloading device at intervals of one by one and then by the transport conveyor. In addition to having a measuring unit, a sorting unit that collects and sorts and sorts each of the plurality of collecting units from the conveyor by a sorting chute based on the measurement result of the measuring unit At the exit of the chute, a cushioning material that gives discharge resistance to the conveyed objects passing through the sorting chute can be swung open and closed around the upper fulcrum so as to move backward from the discharge regulation posture to the discharge possible posture due to the collision of the conveyed objects. When a predetermined supply amount of the transported object is collected in each collecting section, a stopper that blocks the backward displacement of the cushioning material to the discharge possible posture at the exit of the corresponding sorting chute is blocked. Wherein configuration that you have provided release freely.

[Work]

Automatically measure the weight in the measuring unit while transporting the individual items to be transported separately from the hopper with the transport conveyor, and then continue to transport the items based on the measurement results of the measuring unit. It is automatically sorted and collected in the collecting section.

When it is determined that the amount of recovered supply to each recovery unit has reached a predetermined value, for example, by integrating the measurement results of the measurement unit, the exit of the sorting chute to the recovery unit is stopped via a cushioning material. Since it is shut off by the above, the state in which a predetermined supply amount of the objects to be sorted is collected is maintained in the collecting unit.

Further, when the sorted objects to be sorted and collected flow down the sorting chute, the buffer material provided at the exit of the sorting chute so as to be swingable around the upper fulcrum provides the falling resistance of the sorted objects. Since the object to be sorted is prevented from being forcefully sent to the collecting section, the buffer material is also used as a member for restricting the sending of the object to be sorted by the stopper.

〔The invention's effect〕

As a result, the collection unit is always in a state in which only a predetermined supply amount of the transported object is collected, so that the worker does not need to perform extra transfer weighing work thereafter, and the work efficiency of the entire sorting work is improved. Therefore, the labor can be reduced, and it is possible to suppress the occurrence of the problem that the transported object is sent to the recovery section and damaged due to excessive momentum by the selection chute.

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

FIG. 1 shows an automatic sorting device (1) for automatically sorting and sorting long vegetables such as radish, carrot and cucumber as an example of the transported object. This automatic sorting device (1) is a hopper (2) for storing a large amount of long vegetables, a carry-out device (3) for carrying out the long vegetables (a) one by one from a lower portion of the hopper (2) at a predetermined interval. A measuring unit (4) that measures the weight of the long vegetable (a) carried out by the carry-out device (3) while being placed and transported, and a plurality of collecting units (5) for each weight rank based on the measurement results of the measuring unit (4). ) And a sorting section (6) for selective collection.

The hopper (2) is configured to put and store the long vegetables (a) after being washed with water through the upper opening, and the hopper (2) has a plurality of mountain-shaped bend-shaped bent side walls. A posture guide member (7) is provided so that the long vegetables (a) are aligned sideways with respect to the carry-out direction at the time of loading.

The carry-out device (3) is arranged along the lower part of the hopper (2), and carries out a stored material in a horizontal direction and carries it out to the outside of the hopper (2); A second conveyor belt (3b) with a locking projection that is picked up and conveyed obliquely upward from the end of the first conveyor belt (3a). Then, the long vegetables dropped from the end portion of the second conveyor belt (3b) are guided down to the start end portion of the third conveyor belt (4a), which is an example of the conveyor in the measuring unit (4), and the length thereof is increased. A posture changing unit (8) for changing the direction so that the posture is along the conveying direction of the third conveyor belt (4a).
Is provided.

The measuring unit (4) detects the belt downward displacement amount corresponding to the weight of the long vegetables (a) on the lower side of the placing portion of the third conveyor belt (4a) and automatically measures the weight (S). Is provided. Further, the sorting unit (6) has a plurality of collecting units (5) for separately collecting long vegetables (a) classified by weight rank, and is provided on the side of the fourth conveyor belt (6a) as another conveyor. In parallel with the transportation direction, the long vegetables (a) to be transported are provided with a sorting chute (9) toward the corresponding recovery unit (5) based on the measurement result of the measurement unit (4). A plurality of push-out tools (10) for dropping and feeding through are arranged.

That is, the push-out tool (10) is configured such that the corresponding one is driven by the control device (not shown) to which the measurement result of the measurement sensor (S) is given.
