Description

Agricultural products sorter and sorting method {Apparatus For Classifying Agricultural Product and Method For Classifying Agricultural Product}

The present invention divides agricultural products transported from the production area into agricultural products that need to be visually selected by the operator and 'out-of-grade' agricultural products that do not need to be sorted, and the agricultural products that need to be sorted are placed on a tray and given a grade while passing through the sorting device. It is about an agricultural product sorting machine and a method for sorting the agricultural products that can be classified and processed with the categorization process, but can be collected while passing the sorting line for non-grade agricultural products while actually omitting the processing for sorting.

As an apparatus for discriminating conventional agricultural products, for example, in order to determine the grade of agricultural products placed on a tray, the agricultural products are placed on a transfer conveyor with the agricultural products placed on the tray, and when the agricultural products pass in front of the sorting operator, the operator visually sorts and collects the agricultural products. did.

However, as described above, the sorting operation with the naked eye of the sorting operator has a problem in that it is impossible to measure the weight, which requires precise measurement, or the sugar content through a non-destructive test.

In consideration of this point, a sorter has been proposed that measures the weight or sugar content with a measuring device and classifies them by grade when the agricultural products are transported on the conveyor with the agricultural products placed on the tray.

However, there are agricultural products out of grade that do not require measurement for grade sorting among agricultural products that are disembarked from the vehicle. There was a problem that the load was heavy and the work was delayed.

In addition, in the process of disembarking agricultural products, since the operator has to process a large amount in a short time, there is a problem that the operator spends a lot of time to visually classify the agricultural products out of grade.

An object of the present invention is to provide an agricultural product sorting machine and a sorting method that allow an operator to easily classify non-grade agricultural products in a continuously performed alighting process in order to solve the above problems.

In addition, the present invention classifies non-grade agricultural products in the drop-off process and passes the grade information measurement process together with agricultural products requiring grade selection, but the sorter does not perform grade information measurement on agricultural products classified as 'out of grade'. An object of the present invention is to provide an agricultural product sorter and sorting method that can reduce the load on the sorter by preventing or not using grade information.

In addition, the present invention provides an agricultural product sorting machine and a selection method so that agricultural products classified as 'out of grade' can be naturally classified and collected even if they go through a drop-off process.

In addition, an object of the present invention is to provide an agricultural product sorting machine and a selection method that prevent interference between agricultural products by increasing the spacing between agricultural products transported from the transport unit for agricultural product selection.

Referring to FIG. 1 , the agricultural product sorting apparatus 1000 according to an embodiment of the present invention sorts and processes agricultural products that are disembarked from the freight transport means M directly at the disembarkation site.

Agricultural products are loaded in the cargo transportation means (M) and transported to the loading dock, and the transported agricultural products include both visually gradable quality agricultural products and visually 'out-of-grade' agricultural products that do not require grading. can Agricultural products sorting apparatus according to the present invention can be processed together with agricultural products requiring objective grade sorting while also getting off agricultural products judged to be out of grade agricultural products to such an extent that there is no need to perform weight measurement or non-destructive testing by the worker performing the unloading operation. have.

Specifically, the agricultural product sorting apparatus 1000 according to an embodiment of the present invention includes a carrying-in unit 100 in which agricultural products are placed on a tray and continuously transferred, and a tray placed on agricultural products determined to be subjected to a sorting operation in the carrying-in portion. It includes a first tray information detection unit 200 for detecting the information of, and a transport unit 300 arranged downstream of the carry-in unit to transport the tray on which agricultural products are placed.

The carry-in unit 100 is disposed closest to the cargo transportation means (M), and the movement of agricultural products from the cargo transportation means (M) to the carrying-in portion is performed manually by a worker or by a separate automated device. can

Agricultural products sorting apparatus 1000 according to an embodiment of the present invention is a rating information measuring unit disposed downstream of the loading unit 100 to measure rating information on the agricultural products transported by the transport unit 300 . (400), a control unit (500: to be described later with reference to FIG. 4) for pairing the numerical information collected by the first tray information detection unit with the grade information collected by the rating information measuring unit for the same agricultural product, and the At least one sorting and discharging unit 600 for discharging agricultural products to be sorted according to a classification standard in response to a signal from the control unit 500 is provided.

A non-sorted agricultural product processing unit that collects trays in which tray information is not detected by not undergoing a sorting operation further downstream than the location where the last sorting and discharging part is disposed among a plurality of sorting and discharging units 600 disposed downstream of the transport unit 300 (800: Fig. 1) is disposed.

The number of the classification and discharge units 600 is affected according to how subdivided the classification grade is. One sorting and discharging unit 600 is shown to be provided with two sorting conveyors 620 (FIG. 2) for efficiency and speed of work, and a workbench 630 is installed downstream of each sorting conveyor 620, the workbench After the worker P2 collects the agricultural products from the tray at 630 , the empty tray is discharged by the tray discharge conveyor 640 .

When two sorting conveyors are disposed in one sorting/discharging unit 600 , a moving path sorting actuator 610 is disposed on the path of the transporting unit 300 in correspondence with each sorting conveyor 620 .

The movement path selection actuator 610 separates the tray on which the agricultural products recognized as having selection information among the agricultural products transported under the control of the control unit 500 shown in FIG. Change the progress path to proceed to the sorting conveyor (620) of 600.

Based on the traveling direction of the transport unit 300, the classification and discharge unit 600 disposed at the most upstream may classify and collect the highest grade products, and may classify and collect relatively low grade products as it goes downstream. Optionally, based on the progress direction of the transport unit 300, the classification discharge unit 600 disposed at the most upstream classifies and collects the agricultural products with the lowest grade among the selected agricultural products (that is, among agricultural products excluding non-grade agricultural products), As it goes downstream, it is possible to classify and collect relatively high-grade products.

In the drawings, the non-sorted agricultural products processing unit 800 is illustrated as being disposed at the most downstream of the transport unit 300 , but may optionally be disposed upstream than the sorting discharge unit 600 .

Referring again to FIG. 2 to describe the configuration of the carrying-in unit 100 in more detail, the carrying-in unit 100 transports the tray T on which the agricultural products A determined to be selected by the operator are placed. It includes a first track 110 and a second track 120 arranged side by side adjacent to the first track, but conveying a tray on which non-grade agricultural products determined not to undergo a sorting operation are placed.

The first track 110 and the second track 120 include a plurality of conveying rollers 130 extending over the first track and the second track. A plurality of conveying rollers 130 respectively extending perpendicular to the traveling directions of the first track and the second track extend through both the first track 110 and the second track 120 . Accordingly, there is basically no obstacle to the tray T placed on the carry-in unit 100 in moving between the first track 110 and the second track 120 .

However, downstream of the first track 110 and the second track 120 , a tray on which agricultural products already sorted between each track is loaded moves again between the first track 110 and the second track 120 . An isolating unit 140 to block it is installed.

Accordingly, the movement of the tray between the first track 119 and the second track 120 is possible upstream of the carry-in unit 100 before the isolation unit 140 is installed. In addition, as shown in FIG. 3 , the tray T on which the agricultural products are placed can be moved by an external force applied by the operator between the first track and the second track upstream from the position of the isolation unit 140 . do.

Since the worker is positioned proximally to the first track 110, once the agricultural products are mounted on the tray in the first track 110, and then judged as out-of-grade agricultural products by personal judgment, the corresponding tray is set to the second track 120. will be pushed to The tray pushed to the second track 120 cannot be moved back to the first track 110 by the isolator 1400 and continues to be transported along the second track 120.

Sidewalls 102 and 104 are disposed on the outside of the first track and the second track, respectively, so that the tray moves in the track without falling out of the track even if the operator pushes the tray.

The carrying-in unit 100 including the first track 110 and the second track 120 extending parallel to the first track 110 is set to a width of a level through which the tray T can pass through each track.

On the other hand, the extending direction of the carry-in unit 100 is arranged to cross, for example, perpendicular to the extending direction of the transport unit (300).

2 and 3 , the first tray information detection unit 200 is disposed downstream of the first track 110 . The first tray information detection unit 200 is configured to prevent agricultural products from being placed on the tray so as not to interfere with the movement path of the tray while the tray is transferred from the first track 110 to the transport unit 300. It may be disposed on the upper part of the structure upstream of the transport unit 300 at a height not to be interfered with, or may be disposed below the structure upstream of the transport unit 300 .

Tray (T) on which agricultural products (A) are mounted may include, for example, RFID tags in which identification number information assigned to individual trays is readable stored. Accordingly, the first tray information detection unit 200 detects tray information from the RFID tag of the tray when the individual tray T approaches.

The tray (T) on which the agricultural product (A) is mounted is optically irradiated to the agricultural product in the non-destructive inspection unit of the grade information measuring unit disposed on the intermediate path of the transport unit 300, and the light passing through the agricultural product is received. In consideration of this, a light through hole may be provided at the lower portion of the tray T.

The conveying roller 130 of the conveying unit 100 is a conveying roller 130 of the conveying unit 100 such that the tray advances toward the conveying unit 300 by the weight of the tray and the agricultural products in a state where the agricultural products are mounted on the tray. ) may be disposed with an installation height inclined toward the transport unit 300 as a whole. Accordingly, the tray slides on the conveying roller 130 by its own weight and can move toward the downstream of the carry-in unit 100 .

On the other hand, the first tray information detection unit 200 on the tray and the second track 120 that are transported on the first track 110 and proceed to the transport unit 300 through the first tray information detection unit 200 . In order to prevent the trays traveling to the transport unit 300 from being jammed with each other upstream of the transport unit 300 without passing through the second track 120, the movement of the tray is temporarily blocked. A stopper 122 may be provided.

Therefore, the operator P1 basically projects the stopper 122 higher than the conveying surface height of the conveying roller 130 downstream of the second track 120 so that the tray is moved from the second track to the conveying unit 300. It is prevented from proceeding, and a predetermined number of trays are placed downstream of the second track 120 while waiting for discharge. In addition, for a predetermined time when there is no tray entering the upstream of the transport unit 300 through the first tray information detection unit 200 through the first track 110 (that is, there is no processed tray in the first track) The gap between the trays is wide and the second track stops the stopping action of the stop 122 , so that, for example, the stop 122 is below the level of the conveying surface of the conveying roller 130 . By descending to the second track 120, a tray loaded with non-grade agricultural products waiting in the second track 120 is allowed to enter the transport unit 300 .

The stopping action of the stopper 122 may be manually operated by the visual judgment of the operator P1, but optionally there is no tray entering the transport unit 300 through the first track or between trays. The operation of the stopper 122 may be controlled by sensing a moment when a tray having a large interval and being stopped downstream of the second track 120 and waiting to be processed exists.

The first track 110 is arranged proximally to the working side of the operator P1 and the second track 120 is arranged distally to the working side of the operator P1 .

On the other hand, the tray transported by the first track 110 and directed to the transport unit 300 via the first tray information detection unit 200 is transported by the second track 120 and does not go through the first tray information detection unit. It starts from an upstream position on the transport unit 300 rather than the non-transported tray and is transported by the transport unit 300 . Through this arrangement relationship, even if the tray is transported by one transport unit 300, the tray loaded with non-grade agricultural products does not unnecessarily go through the tray information detection step or the detected information is not used for sorting and sorting work, so tray information is detected. It is possible to reduce the load of the work.

2, the above-mentioned rating information measuring unit 400 is a weight sensing unit 410 for detecting the weight of the agricultural product and a non-destructive inspection unit 420 for performing a non-destructive inspection on the agricultural product. includes

The weight sensing unit 410 may measure information on weight as objective numerical information that can be expressed as numerical values of agricultural products to be selected. The weight sensing unit 410 measures numerical information of agricultural products to be sorted, for example, weight information, while the agricultural products to be selected are transported on the transport unit 300 . That is, the weight information of the agricultural products to be sorted is measured while the conveyor of the transport unit 300 is transporting the agricultural products to be sorted at a constant speed without stopping the transport unit 300 .

There are various methods for the weight sensing unit 410 to obtain numerical information of agricultural products to be selected. For example, it is placed on the transport unit 300 through a weight sensor disposed below the transport unit 300 . The weight of the agricultural products to be sorted to be transported can be measured. The position of the weight sensor for measuring the weight of the agricultural products to be sorted is not necessarily limited to the lower side of the transport unit 300, and the weight sensor may be disposed at various positions for appropriate weight measurement.

Since the agricultural products to be sorted are transported on the transport unit 300 while being placed on the tray, the weight sensor measures the sum of the weight of the tray and the agricultural products to be sorted, so the weight minus the standardized tray weight is the weight of the agricultural products to be sorted becomes this

On the other hand, the non-destructive inspection unit 420 for performing a non-destructive inspection on agricultural products, for example, after irradiating light to the agricultural products placed on the tray, and then receiving the light passing through the agricultural products to analyze the characteristics of the light It includes a light analysis unit . The non-destructive inspection unit 420 is disposed on the path through which the tray on which the agricultural products are mounted on the path of the transport unit 300 passes and irradiates downward light. The light irradiated to the agricultural products may be received by a light receiving unit disposed under the transport unit 300 through a hole formed in the lower portion of the tray, and may be received by a separate optical analysis unit. The present invention is not necessarily limited thereto, and the light receiving unit may be disposed on the side of the agricultural product rather than the lower portion.

During the non-destructive inspection of agricultural products in the optical analysis unit, the tray may be optically analyzed at the moment it stays on the transport unit for a short time or passes while continuously moving without stopping.

On the other hand, Figure 4 is a block diagram schematically showing the processing state between the control unit and other components of the agricultural product sorter according to the present invention. The agricultural product sorting apparatus 1000 according to an embodiment of the present invention pairs the grade information collected by the grade information measurement unit 400 with the numerical information collected by the first tray information detection unit 200 for the same agricultural product. It includes a control unit 500 (FIG. 4) to achieve.

Therefore, as shown in FIG. 4 , for agricultural products that are transported by the first track 110 of the carry-in unit 100 and passed through the first tray information detection unit 200 , the tray information contained in the tray recognized is the tray. Grade information of agricultural products contained in the tray corresponding to the information is registered by the control unit 500, and the control unit 500 according to the recognized grade information, the speed at which the tray moves on the transport unit 300, the distance for each section, the section In consideration of the transport time required for each type, the tray on which agricultural products are mounted is discharged and collected by the classification discharge unit 600 of the corresponding grade among the classification discharge units 600 . Even if a tray whose tray information is not recognized reaches the rating information measuring unit 400 , the controller 500 does not allow the rating information measuring unit 400 to perform the rating information measuring step for a tray without tray information. Optionally, even if the rating information measuring unit performs the rating information measuring step for a tray without tray information, the control unit 500 cannot match the measured rating information because there is no tray information, so agricultural products mounted on a tray without tray information We do not use the grade information collected about agricultural products to classify agricultural products.

Agricultural products sorter 1000 according to an embodiment of the present invention is disposed between the grade information measuring unit 400 and the sorting discharge unit 600 to detect again information on trays placed on agricultural products determined to undergo a sorting operation It further includes a second tray information detection unit 700 that does. The control unit 500 calibrates a predetermined position, passage time, and passage fact of the tray in which the agricultural product grade information has been detected through the second tray information detection unit 700 to enable accurate sorting and discharging in the sorting and discharging unit 600 . will take control

As described above, the control unit 500 in the transport unit 300 considers the transport speed of the transport unit, the distance of the section, and the time it takes for the tray to pass through the section, in consideration of the agricultural products mounted on a specific tray and the agricultural products. The grade information is matched.

The speed at which the trays are transported in the transport unit 300 increases downstream for each predetermined section, so that the transport interval between trays can be increased, and interference between adjacent trays and information detection errors can be prevented.

Specifically, as shown in FIG. 1 , in the entire section of the transport unit 300 , the section from the first tray information detection unit 200 to just before the sorting and discharging unit 600 is a belt conveyor made of a flexible material for the transport unit. Since it is composed of a type, it is referred to as a belt conveyor section 300a. After that, the section passing through the sorting and discharging units 600 is such that the tray can easily move in the pushed direction when the movement path selection actuator 610 of each sorting and discharging unit 600 pushes the tray in a predetermined manner. To this end, the transport unit 300 is configured as a top chain conveyor, and the corresponding section constitutes the top chain conveyor section 300b. The top chain conveyor has a rigid structure in which individual pieces are connected to each other to allow relative movement between the pieces to form a conveyor as a whole. The surface of the individual pieces has a relatively smooth surface so that the tray conveyed on the top chain conveyor surface can easily slide by an external force on the conveyor surface.

As shown in FIG. 2 , specifically looking at the belt conveyor section 300a , the upstream of the weight sensing unit 410 of the grade information measuring unit 400 transports the tray by the flat belt conveyor, so the flat belt conveyor section (300a1) is achieved. In the section from the weight sensing unit 410 to the non-destructive inspection unit 420, a path through which light can enter or exit the lower portion of the tray must be formed. A section 300a2 is arranged.

The tray transport speed of the transport unit 300 is set to become faster as it goes downstream for each predetermined section.

Accordingly, the transport speed V2 of the belt belt conveyor section 300a2 is greater than the transport speed V1 of the flat belt conveyor section 300a1, and the top chain conveyor section 300b is greater than the transport speed V2. The feed rate V3 of is set to be larger.

The control unit 500 considers the distance for each section, the transport speed, and the transport required time of the tray for each section, and the rating information measured by the rating information measuring unit only for the tray for which the tray information is detected by the first tray information detecting unit 200 . are combined to match. Therefore, since tray information is not collected in the control unit 500 for trays loaded with non-grade agricultural products transported from the transport unit 300 by bypassing the first tray information detection unit 200, the control unit is mounted on a tray without tray information. Grade information is not measured for agricultural products, and operation control for classification and discharge is not performed even in the classification discharge unit 600 .

On the other hand, the agricultural products sorter 1000 according to an embodiment of the present invention is disposed downstream of one or more of the sorting and discharging units 600, and the non-sorted agricultural products processing unit ( 800) is further included.

Therefore, the control unit 500 matches the measurement value according to the measurement of the grade information with the tray information for the tray in which the tray information is detected, so that the movement path selection actuator 610 of the classification and discharge unit 600 of the corresponding grade passes through the tray. At this time, the transport path of the tray is changed from the transport unit 300 to the sorting conveyor 620 of the sorting and discharging unit. However, the tray loaded with non-grade agricultural products for which tray information is not detected does not receive the transfer path change control of the movement path selection actuator 610 by the controller 500 and continues to move along the transport unit 300 , , eventually reaches the unsorted agricultural product processing unit 800 disposed further downstream than the final classification discharge unit 600 among the downstream of the transport unit 300 to be processed as unsorted agricultural products.

The movement path selection actuator 610 may be a push-type hydraulic machine that pushes the tray through a controlled operation, or an air injector that pushes the tray by injecting high-pressure air into the tray.

Individual configurations of the plurality of fractionation discharge units 600 are illustrated in detail in FIGS. 1 and 2 . The trays transported by the transport unit 300 are pushed by the movement path sorting actuator 610 to a predetermined tray by the sorting and sorting control of the controller 500, so that the pushed tray leaves the transport unit 300 and the sorting conveyor 620 ) will be moved to Since the sorting conveyor 620 is inclined downward in its progress direction and is composed of a plurality of rollers, the tray is moved to the work table 630 prepared in front of the operator P2 by the rotational motion of the rollers.

When the worker P2 removes agricultural products from the tray and collects them, agricultural products classified by specific grades are collected. Empty trays from which agricultural products are separated from the work table 630 are disposed parallel to the sorting conveyor, but inclined downward in the opposite direction, and empty tray transfer conveyors 900: 900a, 900b, 900c through the tray discharge conveyor 640 composed of a plurality of rollers) The empty trays transported to and discharged from each sorting and discharging unit 600 are supplied back to the loading unit 100 through the empty tray transfer conveyor 900 . In order to prevent empty trays from entering the carry-in part without any restrictions in the process of re-supplying the empty trays to the carrying-in unit 100 and to allow an appropriate amount of empty trays to enter the carrying-in part 100, an empty tray transfer conveyor 900 ) and the carry-in unit 100 may be provided with a separate empty tray transfer stop (not shown) for controlling the entry of the empty tray.
