Description

Technical Field

[0001] This utility model relates to the field of agricultural product sorting equipment technology, specifically to an automatic sorting and screening device for olive fruits. Background Technology

[0002] As a high-value crop, olive fruit exhibits significant differences in nutritional composition, appearance, and storage performance depending on its origin, variety, and harvesting period. Therefore, post-harvest processing and subsequent stages often require categorized management and storage based on origin information to facilitate subsequent component testing (such as squalene and hydroxytyrosol) and traceability.

[0003] Most existing olive fruit sorting devices focus on image recognition screening based on the appearance characteristics of the fruit, such as size and color. These devices are complex in structure, costly, and prone to large recognition errors. At the same time, they generally lack supporting structures for information recording and subsequent traceability, making it difficult to effectively correspond the test results with the actual batch of fruit, resulting in inconvenience in processing and management.

[0004] Therefore, there is an urgent need for an automatic olive fruit sorting and screening device with a simple structure, basic information input and corresponding sorting capabilities, and support for backfilling of detection data, in order to solve the shortcomings of existing equipment in terms of material identification accuracy and information traceability.

[0026] like Figure 1-4 As shown, an automatic sorting and screening device for olive fruits includes a feeding structure 1, an information input module 2, a guiding and sorting structure 3, a control module 4, and multiple storage bins 5.

[0027] Among them, the feeding structure 1 is a conveyor belt structure that transports the harvested olives to the guiding and sorting structure 3 in an orderly manner.

[0028] Information input module 2 is located at the front of the device or on the control panel. It is used to input basic data (origin, variety, harvest date, etc.) for each fruit batch and can use various input methods, including:

[0029] a) Capacitive Touchscreen: Includes a graphical user interface display unit and a touch input unit. The interface has multiple preset input fields (such as drop-down options or a numeric keypad), and users select or input information through touch operations. After the information is entered and the user clicks "Confirm," an internal event response mechanism is triggered, and the encoded information is transmitted to control module 4.

[0030] b) Button input device: Multiple physical buttons are provided, each corresponding to a specific field option. For example, there are preset buttons for "Origin" and "Variety," which select the corresponding value when pressed. Combination buttons control switching between input items or confirming input. The system converts button level signals into field values ​​and then transmits them to the control module.

[0031] c) Rotary input device: This device allows for rotary encoder control of option switching, with function keys used to confirm field selection. For example, rotating the knob selects "Harvest Period," pressing confirms, and then proceeds to the next field. The device has a built-in microprocessor responsible for mapping the knob rotation amount to the current field status using standard encoding.

[0032] d) QR code scanner: By scanning the pre-made batch QR code, it automatically parses its embedded fields (such as place of origin = XX, harvest period = XX, etc.), and transmits them to the control module through the USB / serial interface. The system completes the field mapping and enters the confirmation stage.

[0033] All input methods are structured in a unified format (such as JSON string) and sent to control module 4. The control module then processes the subsequent mapping and sorting action instructions.

[0034] Information input module 2 is connected to control module 4 via a serial communication interface (such as RS232 or USB). The fruit information entered is transmitted to the control module after being encoded. The microprocessor in the control module receives the data and stores it in the information storage unit, and generates sorting control signals accordingly. If a barcode scanning module is used, the QR code information collected by the barcode scanner is transmitted via the USB interface and the fields (such as "origin" and "variety") are automatically identified. The system automatically performs field parsing and matching to achieve standardized information entry and automatic binding.

[0035] The control module 4 connects the information input module 2 and the guide sorting structure 3. After receiving the input information, it determines the fruit category and controls the action of the guide structure to send the batch of fruit into the designated storage bin 5.

[0036] The specific workflow is as follows: Olives are continuously conveyed by the conveyor belt feeding structure 1. When they reach the front sensor area of ​​the guide sorting structure 3, the infrared sensor or photoelectric sensor detects the fruit's arrival signal and sends a trigger signal to the control module 4. The control module 4 searches for the corresponding bin number based on the currently entered fruit information (including origin, variety, harvest period, etc.) and generates a sorting action instruction.

[0037] The sorting action command controls the turntable guide structure to rotate to the feed inlet position of the corresponding storage bin, and the angle is precisely controlled by a stepper motor. Simultaneously, the conveyor belt enters a brief stop state. Once the action is completed and confirmed by the position sensor, the control module resumes the conveyor belt operation, allowing the fruit to fall stably into the target position. This process enables one-to-one fruit sorting and automatically records the corresponding relationships.

[0038] Control module 4 internally includes an information processing unit, a mapping storage unit, and an execution control unit, and its workflow is as follows:

[0039] ① The information processing unit receives structured field information (such as “origin = XX”, “variety = YY”, “harvest period = ZZ”) from the information input module 2 and combines them as key fields;

[0040] ② The mapped storage unit has a pre-defined rule table that records the binding relationship between different field combinations and storage bin numbers. For example:

[0041] “Origin = Province A + Variety = O1 + Harvest Period = September” → Warehouse No. 1;

[0042] “Origin = Province B + Variety = O2 + Harvest Period = October” → Warehouse No. 2;

[0043] The rule table mentioned above can be implemented through a built-in configuration file or a database, and supports manual modification and dynamic updates.

[0044] ③ The judgment logic is based on a complete matching mechanism: The system standardizes the input fields (such as unifying the date format and filling in empty values), and then compares them item by item with the mapping table. After confirming the target warehouse number, the number information is sent to the execution control unit.

[0045] ④ The execution control unit looks up the corresponding guide structure angle value or action code according to the target compartment number, for example, "number 3 → lever angle = 90°", or "number 5 → flip plate number = 2 action";

[0046] ⑤ The control module will generate control commands (such as serial port command: "#SET_POS=90") and send them out through the drive circuit to control the actuator (such as stepper motor or pneumatic cylinder) of the guide sorting structure 3 to complete the action;

[0047] ⑥ Once the position sensor confirms that the action has been completed, the system allows the conveyor belt to continue running and enter the next fruit processing cycle.

[0048] In addition to the rotary table structure, the guiding and sorting structure 3 also includes optional paddle or flip-plate structures, all located at the end of the conveyor belt 1, and used to switch the path and orient the fruit under the command of the control module 4.

[0049] a) Rotary structure: Includes a sorting turntable with a through hole, a central rotating shaft, a motor drive unit, and a photoelectric positioning sensor. The rotation of the turntable causes the olives to fall into the corresponding storage bin after the through hole aligns with the inlet of the storage bin.

[0050] b) Paddle-type structure: Includes a paddle body, a rotating shaft, a drive motor, and a positioning sensor. The paddle is horizontally mounted above the feed inlet via the rotating shaft. The drive motor is connected to the side of the rotating shaft and controls the paddle to switch between different angles via gear or belt transmission. The control module outputs a control signal to drive the motor, causing the paddle to rotate to the slide direction of the designated compartment, guiding the fruit into the corresponding storage compartment. The positioning sensor is used to detect the current position of the paddle and provide feedback on the completion of the action.

[0051] c) Flip-plate structure: This includes a flip plate, a hinged connecting shaft, and a linear actuator or cylinder device. The flip plate is installed below the fruit path and is normally in a horizontal, closed state. Upon receiving a signal from the control module, it flips to a 45° or 90° opening angle, allowing the fruit to fall into the designated branch channel. This structure is suitable for multi-row outlet structures and offers rapid response.

[0052] All of the above structures are controlled by commands issued by the control module 4, and are used in conjunction with sensors to achieve accurate delivery.

[0053] Each storage compartment 5 is structurally independent and includes an information identification area 6. This area displays information such as the origin, variety, harvest date, and test results of the fruit currently stored in the compartment. The implementation can be either static or dynamic.

[0054] a) Static labeling method: This is achieved through insertable labels (paper / plastic material) or QR code sticker panels. Information is filled in manually or printed and then affixed to the surface of the warehouse. This method is suitable for situations where the information does not change frequently.

[0055] b) Dynamic electronic display method: Utilizing a low-power electronic paper display or OLED character screen, connected via a data bus (such as I...). 2 (C or SPI) is connected to control module 4. After sorting is completed or detection data is entered, the control module matches the corresponding display content according to the bin number, and sends the text or image content to the corresponding display unit through serial port commands or communication protocols to achieve dynamic refresh;

[0056] c) Electronic tag (e.g., RFID) method: Each warehouse is equipped with a write-type RFID tag module. The control module writes the corresponding data into the tag memory through the RFID writer, and external devices can read and verify the information. This method is suitable for offline data transmission scenarios in the traceability chain.

[0057] Different labeling formats can be selected according to usage requirements. Among them, the dynamic labeling method can automatically synchronize and update information in conjunction with the control module software system, improving the efficiency and accuracy of information management. At the same time, the device is equipped with a data backfilling interface 7, which is used to input laboratory test results into the control module 4, and after processing by the control module, display them in the labeling area 6 of the corresponding storage compartment 5.

[0058] The interface includes a USB interface, a Wi-Fi module, or a Bluetooth communication module, with a USB interface preferred to ensure input data stability. Testing personnel upload standard structured data files to the device via a USB flash drive or host computer. File formats include .csv or .json, etc.

[0059] The following is an example of a .csv file:

[0060] "Storage unit number, squalene content (%), hydroxytyrosol content (mg / kg), test date"

[0061] "3,0.18,55.2,2025-08-30"

[0062] The .json format example is as follows:

[0063] {"Storage Unit Number":"3","Squalene Content":"0.18","Hydroxytyrosol Content":"55.2","Test Date":"2025-08-30"}

[0064] Control module 4 has a built-in data parsing unit that processes data according to the following procedure:

[0065] ① After receiving the data file, the format is identified. If it is .csv, the fields are separated by commas; if it is .json, the parsing module is called to extract the fields.

[0066] ② The extracted "warehouse number" field is used to match the location of storage warehouse 5, and the other fields are stored in the information mapping table as auxiliary detection data of the warehouse.

[0067] ③ The system calls the refresh interface of the electronic screen corresponding to the identification area 6, and displays the information such as "squalene content", "hydroxytyrosol content", and "test date" on the screen or label after formatting;

[0068] ④ If a file field is missing, the number is abnormal, or the format is incorrect, the system will trigger an error message mechanism, displaying a message such as "Data backfilling failed, please check the format" on the interface, while retaining the original data unchanged;

[0069] ⑤ Log records are automatically generated after successful data entry, facilitating later traceability and data backup.

[0070] This utility model has a reasonable structure, a high degree of automation, and is easy to operate. It is especially suitable for olive planting bases, primary processing plants, research institutions and other places, improving the efficiency of batch management of fruits and avoiding the problems of misplacement and mixed placement.

[0071] Furthermore, to enhance the preservation of olives during storage, a miniature preservation module can be added to each storage compartment without altering the main structure of the device. This module includes a low-power semiconductor cooling chip, a temperature sensor, a sealing gasket, and a power control circuit. It enables independent adjustment and constant control of the internal temperature of each compartment, maintaining it within a suitable storage temperature range (e.g., 10℃~15℃) to delay fruit spoilage and component changes. The cooling chip can be a TEC1-12706 type, using aluminum heat sinks for heat exchange and controlled by a temperature control chip. Flexible silicone sealing strips are installed at the edges of the compartment doors to enhance sealing. This preservation structure is optional and will not affect the normal operation of the device's sorting, screening, and information traceability functions.

[0072] The above description is only a preferred embodiment of this utility model. Those skilled in the art can make equivalent adjustments to the structure without departing from the core concept of this utility model, and such adjustments still fall within the protection scope of this utility model.
