Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a device for sorting and sorting crops, mainly fruits and vegetables, and more specifically, the present invention relates to a device for sorting and sorting crops such as fruits and vegetables, and more specifically, the present invention relates to a device for sorting and sorting crops such as fruits and vegetables. A measuring means for measuring the weight of the crop is provided on the upper side of the conveyance, and a plurality of collection tools are arranged in parallel along the conveyance route on the lower side of the conveyance, and the measuring means is configured to measure the weight of the crop. Based on the results, the present invention relates to a crop sorting device in which a plurality of dispensing tools for dispensing and guiding crops from the endless rotary belt toward the corresponding collecting implements for each weight rank are arranged in parallel along a conveyance path.

[Conventional technology]

In the above-mentioned crop sorting device, it has conventionally been considered that the dispensing tool is oscillated by an electromagnetic solenoid around an axis along the transport direction on the northern side to push out the crops toward the collecting tool. (For example, see Japanese Patent Application No. 254211 filed by the present applicant).

[Invention or problem to be solved]

On the other hand, in the case of the conventional structure described above, the entire area of the dispensing tool's tip action area is moved in parallel in a direction perpendicular to the moving direction of the endless rotating belt for loading and conveying.
The dispensing tool must push the crops placed and transferred sideways against the transfer force, which requires a large driving force, and
In order to increase the horizontal push stroke, it is necessary to increase the swing length, which has the disadvantage of increasing the size of the device.

In addition, since the tip acting portion moves in parallel, there is also a drawback that when returning to the standby position after extrusion, there is a risk that subsequent crops will be caught and released from the conveyance surface.

The present invention aims to solve the above-mentioned problems by rational structural improvement.

[Means to solve the problem]

A characteristic configuration of the present invention resides in that, in the crop sorting device described at the beginning, each of the dispensing tools is configured to swing around a vertical axis using the upper side of the conveyance as a fulcrum.

[For production]

Each dispensing tool swings around the upper side of the conveyor to guide the dispensing of the crop, so the dispensing implements have two positions: a working position in which the crop is traversed obliquely above the endless rotating belt, and a standby position along the conveying direction. It will be switched across. As a result, in any operating state, there is no problem such as the edge of the dispensing tool getting caught on the subsequent conveyed crop and hindering the conveyance, and moreover, from the standby position to the working position. When switching to the top position, the tip of the crop lightly touches the crop, causing the crop to change its posture diagonally, and then the crop is smoothly collected using the conveying force of the endless rotating belt and the guidance function of the dispensing device in the diagonal position. You can also send it out towards the tool.

〔Effect of the invention〕

Therefore, according to the present invention, it is possible to smoothly unload crops without causing transportation obstruction through rational structural improvements, and the driving force of the unloading tool is sufficient to horizontally push the entire weight of the crops to be loaded and transferred at once. It only needs to be smaller than the conventional one, and the impact force on the crops is also small, reducing the risk of damage.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

Figure 1 shows crops such as carrots, radish, and other long vegetables (a)
This figure shows an automatic crop sorting device that sequentially carries out crops from a storage hopper (1) and automatically weighs and sorts them. This automatic sorting device includes an unloading device (3) that loads and locks the crops (a) one by one using a locking projection (2) from the bottom of a storage hopper (1), and then unloads them individually. an aligning unit (4) that sequentially arranges the crops (a) sent out from the plant in a vertical line; a measuring unit (5) that automatically measures the weight of the crops (a) after they are continuously placed and transported; based on the measurement results; and multiple collection tools (
6) is a sorting section (7) that sorts and collects crops according to each weight rank.
).

The measurement unit (5) measures the downward displacement of a detection member (9) disposed on the lower side of the conveyor belt (8) based on the weight of the crop while the crop is placed on the endless conveyor belt (8) and conveyed. The amount is detected by a weighing sensor (S) [an example of a measuring means], and the transport timing is set so that only one crop (a) is always placed on the transport belt (8), and the measurement is performed. Efforts are being made to improve accuracy. In other words, transport bell + (8)
An optical sensor (10) for detecting that the crop (a) has passed is disposed at the starting end of the conveyance of the crop (a), and after this sensor (10) detects the preceding crop (a), If the crop (a) is stored and collected in the collection section for reprocessing (11) without being subjected to post-process sorting work, if it is within a predetermined set time or the time until detection of I have made it possible.

Next, the structure of the sorting section (7) will be explained.

As shown in FIGS. 2 and 3, the sorting section (7) includes the measuring section (
A plurality of collection tools (6) are installed along the conveyance direction on the side of the endless rotating belt (12) on which the crops (a) are placed and conveyed in a continuous manner.
) are arranged in parallel, and based on the measurement results from the measuring section (5), an endless rotating belt (12) is installed for each weight rank.
A plurality of dispensing tools (13) for dispensing and guiding the crops (a) from above toward the corresponding collecting tools (6) are arranged in parallel along the conveyance path. Each of the dispensing tools (13) is swingable to switch between a standby position along the transport direction and an active position diagonally across the transport path around the vertical axis on the upper side of the transport of the endless rotating bell + (12). and is biased and held in the standby position by a tension spring (14). and,
It is configured so that the drive is switched to the working position by excitation driving of the electromagnetic solenoid (15).

In its standby position, each of the dispensing tools (13)
On one side of the conveyor belt (12), guide walls are arranged in parallel to form a guide wall on the lateral side of the conveying route, and on the opposite side of the conveying route, there are guide walls to prevent the conveyed crops from rolling down. A small protrusion (16) is formed. In addition, each electromagnetic solenoid (15) is connected to the crop (a) that has passed or is measured by an optical sensor (17) disposed at the terminal end of the measuring section (5).
Or, it is configured to control the driving time after a set time has elapsed to reach the collection point corresponding to the weight rank.

In this way, since the dispensing tool (13) is configured to swing around the fulcrum on the upper side of the conveyor, when switching and swinging, problems such as accidentally catching and locking the succeeding crop may occur. Without further ado, as shown in Figure 2, the conveyor bell 1
- It functions as a guide surface by utilizing the conveying force of (12), and the discharging operation can be performed smoothly without damaging the crop (a).

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
