Description

[Detailed description of the invention] [Industrial application field] The invention uses crops such as ginseng, radish, and other root vegetables.
The present invention relates to a crop sorting apparatus configured to automatically carry out sorting by measuring the weight while successively carrying out from a storage location and continuously transporting.

[Conventional technology]

Conventionally, in the crop sorting apparatus having the above-described configuration, a crop is transported from a storage location, transported, weighed, and then configured as a series of transport paths from sorting to collection. The measuring unit includes a plurality of measuring devices arranged side by side, and the arranging unit arranges the crops one by one and supplies the crops to the respective measuring devices.

[Problems to be solved by the invention]

The conventional structure described above is such that the crops are sequentially conveyed one by one in a tandem manner so that automatic weighing and sorting and collecting can be performed with high accuracy.

By the way, according to the above-mentioned conventional structure, in order to improve the accuracy of automatic weighing and sorting and collecting, it is desirable to supply the crops evenly to each weighing device. This causes supply unevenness to the weighing device.

Therefore, in a weighing device with a large supply amount, clogging due to stagnation in the alignment unit occurs, and in a weighing device with a small supply amount, there is a disadvantage that the work efficiency is reduced.

Conventionally, when a crop stays in an arrangement part, it overflows to a lateral outside part, collects it by a conveyor, and returns it to a storage hopper.

According to the above-mentioned conventional means, crops overflowing in the column portion are circulated to prevent clogging in the alignment portion. Therefore, there is a disadvantage that crops are easily damaged by circulation of crops.

An object of the present invention is to prevent a crop from being clogged in an alignment portion without damaging the crop.

[Means for solving the problem]

The features of the present invention include an unloading unit for loading and unloading crops from the storage hopper, an alignment unit for arranging the crops in a plurality of columns while transporting the crops, and measuring the weight of the transported crops. Each of the post-processing units that sort and collect
In a crop sorting device provided along a continuous transport path, a guide member for distributing transported crops in a plurality of columns is provided in the unloading section, and the staying of crops in each column portion is separately detected in the alignment section. A clogging sensor is provided, and the guide member is operated in the horizontal direction based on the crop stagnant detection by the clogging sensor in each of the tandem portions, so that the column portion of the crop non-stagnant portion is more than the column portion of the crop stagnant portion. The sensor and the guide member are linked so that more crops are supplied to the feeding section, and further, the drive speed of the transport conveyor of the unloading section is set to a lower speed based on the detection of crop stagnation by the plurality of sensors. In order to control the sensor, the sensor and the transport conveyor in the unloading section are linked to each other.

[Action]

When the crop is stagnated at the alignment unit that arranges the crops in a plurality of columns while transporting the crops due to the bias of the crops on the conveyor, the jam detection sensor detects it, and the guide member is moved based on the detection result. Actuated laterally to provide more crop to less stagnant locations. Then, when the stagnant crops occur simultaneously at a plurality of locations in the alignment section, the driving speed of the transport conveyor is controlled to a lower side based on the detection result of the clogging detection sensor.

[Effect of the invention]

As a result, it is possible to prevent crops from being clogged at the alignment section without damaging the crops, and to improve the work efficiency by changing the ratio of the supply amount of the crops according to the situation of the clogging. it can.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Fig. 1 shows an automatic crop that automatically removes crops (a) from a hopper (1) that stores a large amount of crops (a) such as carrots, radishes, and other long vegetables, and then automatically measures and sorts and collects them while transporting them. 3 shows a sorting device. The automatic sorting apparatus is configured such that an unloading section (2) for loading and unloading a crop (a) from the bottom of a hopper (1) for storing a crop (a) is arranged in a column while loading and transporting the crop (a). An alignment unit (3) to be weighed, a weighing unit (4) for measuring the weight of the transported crop, and a sorting unit (6) for sorting and collecting the crop (a) in a plurality of collecting tools (5) based on the weighing results. They are arranged side by side along a continuous transport path.

More specifically, the unloading section (2) is composed of a wide-width, single-structure, flat-belt-type first conveyor (7) disposed along the bottom of the hopper (1), and a first conveyor (7). A second transporting conveyor (9) having a locking projection (8) having the same width and a single structure for latching and transporting the crop (a) obliquely upward to the end portion, and the alignment portion (3) is wide. While placing and transporting the crop (a) by the single-structured flat belt-type transport conveyor (10), the sorting guide member (1) is mounted on the side wall (11).
According to 2), the crop (a) is arranged in four columns while abutting and guiding. At the end of the arranging section (3), a single feed mechanism (13) for sequentially feeding the crops (a) conveyed in tandem one by one toward the measuring section (4) in the subsequent process. Is provided. As shown in FIG. 3 to FIG. 5, the single-piece delivery mechanism (13) is configured such that the crops (a) conveyed from the alignment section (3) are placed one by one from the lower standby position in the horizontal direction. Four discharge tools (14) are provided for swinging upward around the axis (X1) within a certain range and sliding toward the measuring section (4), and crops are provided on both sides of the discharge tool (14). Inclined guides (15) and (15) are provided for guiding (a) toward the respective ejectors (14). A relay guide (16) is provided on the upstream side of each of the ejectors (14), and the guide (16) is interlocked with the swing of the ejector (14) returning to the standby position. Then, the crop (a) is swung upward from the lower guiding posture around the horizontal axis (X2) to push up the crop (a) and guide the transfer to the discharger (14). A receiving member (1) for receiving only one crop on the swinging fulcrum side of the discharge tool (14) so that four or more crops (a) are not erroneously placed on the discharge tool (14).
7) is provided.

As shown in FIG. 4, an optical sensor (18) for detecting that the crop (a) has erroneously stayed at the location at the upper position of the inclined guide portion (15) is provided at each discharging tool ( In response to the detection operation of the sensor (18), the distribution guide member (12) is driven by an electromagnetic solenoid (not shown) around the vertical axis (Y) on the lower side of the conveyance.

Further, when the above-mentioned stagnation occurs at a plurality of locations, the rotation speed of the driving motor (M) of the first and second transport conveyors (7) and (9) is controlled to a low speed side. It is.

The weighing section (4) and the sorting section (6) are configured to have two rows of transport paths by two flat belt type endless rotating belts (19) and (20) arranged in parallel. To the weighing section (4), the discharge tools (14), (14) provided one by one for each transport path alternately feed the crops (a) one by one at regular intervals. It is configured as follows. The measuring section (4) is an endless rotating belt (1
