Description

Technical Field

[0001] This invention relates to the field of sorting machines, and particularly to high-speed sorting machines. Background Technology

[0002] Logistics work mainly includes seven components: transportation, warehousing, packaging, handling and loading / unloading, distribution processing, delivery, and related logistics information. Among these, sorting is an essential part of the distribution processing. Sorting machines are the main equipment in the sorting process. They sort items according to pre-set computer instructions and deliver the sorted items to designated locations.

[0003] Existing sorting machines typically sort one type of item during operation. However, when sorting two types of items is required, operators need to set up two sorting mechanisms to carry out the work, which increases the length of the sorting line and expands the work area occupied by the sorting process, greatly increasing the operator's capital investment.

[0004] Therefore, high-speed sorting machines are needed to achieve multi-category sorting and improve sorting efficiency. Summary of the Invention

[0005] This invention provides a high-speed sorting machine, including a positioning roller conveyor, an accelerating belt conveyor, a sorting host, at least two sorting channels, a data acquisition module, and a main control module. The positioning roller conveyor transports items to be sorted to the accelerating belt conveyor, which then accelerates the transport of the items to be sorted to the sorting host. The data acquisition module includes a position sensing component and a barcode scanning component. The position sensing component collects the position information of the items to be sorted on the accelerating belt conveyor. The main control module controls the barcode scanning component to scan the items to be sorted based on the position information collected by the position sensing component, obtaining barcode data. The main control module also determines the corresponding sorting channel for each item based on the barcode data and controls the sorting host to sort the items to the corresponding sorting channel.

[0006] Furthermore, the data acquisition module includes a first photoelectric sensor, a second photoelectric sensor, and a barcode scanner. The first photoelectric sensor is disposed at one end of the accelerator conveyor near the alignment roller conveyor, and the second photoelectric sensor is disposed at one end of the accelerator conveyor near the sorting host. The main control module is used to control the barcode scanner to scan the item to be sorted on the accelerator conveyor based on the position information of the item to be sorted collected by the position sensing component. This includes: when the first photoelectric sensor is triggered by the item to be sorted, acquiring the real-time transport speed of the accelerator conveyor; determining the predicted trigger time of the second photoelectric sensor based on the real-time transport speed of the accelerator conveyor and the trigger start time of the first photoelectric sensor; and controlling the barcode scanner to scan the item to be sorted based on the predicted trigger time of the second photoelectric sensor.

[0007] Furthermore, the main control module determines the predicted trigger time of the second photoelectric sensor based on the real-time transport speed of the acceleration belt conveyor and the trigger start time of the first photoelectric sensor, including: acquiring the distance between the first photoelectric sensor and the second photoelectric sensor; calculating the transport time based on the distance between the first photoelectric sensor and the second photoelectric sensor and the real-time transport speed of the acceleration belt conveyor; and determining the predicted trigger time of the second photoelectric sensor based on the trigger start time of the first photoelectric sensor and the transport time.

[0008] Furthermore, the main control module controls the scanning component to scan the items to be sorted based on the predicted trigger time of the second photoelectric sensor, including: determining a trigger time range based on the predicted trigger time of the second photoelectric sensor; and controlling the scanning component to scan the items to be sorted when the second photoelectric sensor is triggered within the trigger time range.

[0009] Furthermore, the sorting host includes a sorting table, multiple sorting rollers, and a swing adjustment assembly. The sorting rollers are partially embedded in the sorting table. The main control module is also used to adjust the rotation angle and rotation speed of each sorting roller through the swing adjustment assembly.

[0010] Furthermore, the main control module adjusts the rotation angle and rotation speed of each sorting wheel through the swing adjustment component, including: acquiring the size and weight information of the item to be sorted; determining the optimal rotation angle and optimal rotation speed of each sorting wheel corresponding to the item to be sorted based on the sorting channel corresponding to the item to be sorted and the size and weight information of the item to be sorted; predicting the end time of sorting the previous item to be sorted; and adjusting the rotation angle and rotation speed of each sorting wheel according to the optimal rotation angle and optimal rotation speed of each sorting wheel corresponding to the item to be sorted at the predicted end time of sorting the previous item to be sorted.

[0011] Furthermore, the main control module acquires the size information of the item to be sorted, including: acquiring the trigger end time of the first photoelectric sensor corresponding to the item to be sorted; calculating the length of the item to be sorted based on the trigger start time of the first photoelectric sensor, the trigger end time of the first photoelectric sensor corresponding to the item to be sorted, and the real-time transport speed of the accelerator belt, wherein the size information of the item to be sorted includes at least the length.

[0012] Furthermore, a third photoelectric sensor is also provided on the sorting table; the main control module predicts the end time of sorting the previous item to be sorted, including: when the third photoelectric sensor is triggered by the item to be sorted, obtaining the trigger start time of the third photoelectric sensor; predicting the sorting time required for the previous item to be sorted based on the length of the previous item to be sorted and the optimal rotation angle and optimal rotation speed of each sorting wheel corresponding to the previous item to be sorted; and predicting the end time of sorting the previous item to be sorted based on the trigger start time of the third photoelectric sensor and the sorting time required for the previous item to be sorted.

[0013] Furthermore, each sorting channel is also equipped with a fourth photoelectric sensor; the main control module is also used to perform sorting channel verification according to the sorting channel corresponding to the item to be sorted when the fourth photoelectric sensor is triggered.

[0014] Furthermore, the data acquisition module also includes a positioning roller conveyor status monitoring unit, an acceleration belt conveyor status monitoring unit, and a sorting host status monitoring unit. The positioning roller conveyor status monitoring unit collects the status information of the positioning roller conveyor, the acceleration belt conveyor status monitoring unit collects the status information of the acceleration belt conveyor, and the sorting host status monitoring unit collects the status information of the sorting host. The main control module is also used to perform fault diagnosis based on the status information of the positioning roller conveyor, the acceleration belt conveyor, and the sorting host.

[0015] Compared with existing technologies, the high-speed sorting machine provided by this invention has at least the following beneficial effects: 1. By coordinating the alignment roller conveyor and the acceleration belt conveyor, items to be sorted can be quickly transported from their initial position to the sorting host. This design reduces the waiting time of items during the sorting process, thus significantly improving sorting efficiency. The position sensing component in the data acquisition module can collect the position information of the items to be sorted on the acceleration belt conveyor in real time, which allows the main control module to accurately control the scanning timing of the barcode scanning component. Through precise barcode scanning, the system can accurately obtain the barcode data of the items to be sorted, thereby determining their corresponding sorting channel and achieving accurate sorting. The entire sorting process is controlled by the main control module. From collecting position information, scanning, determining the sorting channel, to controlling the sorting host to perform sorting, everything is completed automatically. This greatly reduces manual intervention and improves the degree of automation in sorting. Because the system can automatically determine the sorting channel based on the barcode data, it can adapt to the sorting needs of different types and specifications of items. This allows the high-speed sorter to perform excellently in a variety of application scenarios. Through the cooperation of the data acquisition module and the main control module, the system can record the barcode data and sorting channel information of each item to be sorted. This helps achieve data traceability, providing strong support for subsequent logistics management and analysis.

[0016] 2. By setting a distance between the first and second photoelectric sensors and combining this with the real-time conveyor speed of the belt conveyor, the transport time of the items to be sorted from the first to the second photoelectric sensor can be accurately calculated. The main control module predicts the trigger time of the second photoelectric sensor based on this transport time and controls the barcode scanning component to scan within the predicted time range. This design ensures that the barcode scanning component scans when the items to be sorted reach the optimal scanning position, thereby improving scanning accuracy. By predicting the trigger time of the second photoelectric sensor, the main control module can prepare the barcode scanning component in advance, ensuring immediate scanning upon the arrival of the items. This design avoids scanning failures or incomplete scanning data caused by delays in the barcode scanning component's activation, thus improving sorting efficiency.

[0017] 3. By precisely adjusting the rotation angle and speed of the sorting wheel, it is ensured that items are accurately and stably sorted into designated channels. This design reduces problems such as item slippage and jamming caused by improper rotation of the sorting wheel, thus improving sorting accuracy. Determining the optimal rotation angle and speed based on the actual size and weight of the items maximizes the sorting capacity of the sorting machine. By predicting the end time of the previous item's sorting, the preparation for the next item can be adjusted in a timely manner, reducing waiting time and improving sorting efficiency. This design allows the sorting machine to adapt to items of different sizes and weights, improving the system's flexibility and applicability. Attached Figure Description

[0018] This specification will be further described by way of exemplary embodiments, which will be described in detail with reference to the accompanying drawings. These embodiments are not limiting; in these embodiments, the same reference numerals denote the same structures, wherein:

[0019] Figure 1 This is a structural schematic diagram of a high-speed sorting machine according to some embodiments shown in this specification; Figure 2 This is a schematic diagram of a high-speed sorting machine according to some embodiments of this specification.

[0020] In the diagram, 1 is the alignment roller conveyor; 2 is the acceleration belt conveyor; 3 is the sorting main unit; and 4 is the sorting channel. Detailed Implementation

[0021] To more clearly illustrate the technical solutions of the embodiments in this specification, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are merely some examples or embodiments of this specification. For those skilled in the art, these drawings can be applied to other similar scenarios without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.

[0022] Figure 1 This is a structural schematic diagram of a high-speed sorting machine according to some embodiments shown in this specification. Figure 2 These are schematic diagrams of modules of a high-speed sorting machine according to some embodiments of this specification, such as... Figure 1 and Figure 2 As shown, the high-speed sorting machine includes a positioning roller conveyor 1, an acceleration belt conveyor 2, a sorting host 3, at least two sorting channels 4, a data acquisition module, and a main control module. The positioning roller conveyor 1 is used to transport the items to be sorted to the acceleration belt conveyor 2, and the acceleration belt conveyor 2 is used to accelerate the transport of the items to be sorted to the sorting host 3.

[0023] The main control module is responsible for coordinating the entire system, controlling the alignment roller conveyor 1, the acceleration belt conveyor 2, and the sorting host 3. It also interacts with the host system, collecting system information in real time and providing it for querying, while receiving control commands from the host system and executing the corresponding actions. The main control module uses a CPU1515-2PN as the controller to manage the entire machine. It uses dual photoelectric recognition to scan and upload barcode data of the items to be sorted in real time, and quickly distinguishes and extracts commands from the host system to ensure accurate sorting of the sorting host 3. It also performs precise sawing adjustments to the items to be sorted. A servo motor is used to achieve high-speed, precise positioning of the sorting wheels on the sorting host 3.

[0024] The main control module uses a Schneider AVT310 frequency converter to drive the Nord motor and control the operating speed of the sorting host 3. Its main functions are as follows: 1. Control the start, stop, and emergency stop of the sorting host 3; 2. Real-time control of the operating speed of the sorting host 3 to ensure stable operation of the sorting host 3; 3. Implement graded control of the speed of the sorting host 3, setting different operating speeds to match different sorting efficiencies; 4. Protect the sorting host 3, and alarm or shut down the machine in case of failure to ensure the safe operation of the sorting host 3.

[0025] During the movement of the items to be sorted on the alignment roller conveyor 1 and the acceleration belt conveyor 2, the main control module can control the alignment roller conveyor 1 and the acceleration belt conveyor 2 to increase their speed step by step, so that the originally connected boxes can be separated by speed difference in the simplest way to achieve the pulling distance of the items to be sorted.

[0026] The sorting host 3 uses the Boke FD5 series servo controller to control the SMC series servo motors. Its main functions are as follows: 1. It can achieve vibration suppression and precise positioning, ensuring accurate swing within 100ms after receiving a steering command; 2. It achieves absolute value positioning, ensuring that the device does not need to return to the origin point after each power outage; 3. The swing velocity curve can be controlled in an S-shape to ensure that the optimal curve is achieved during the swing process, and the tilting of the items to be sorted will not cause the box to have too much swing inertia.

[0027] The data acquisition module includes a position sensing component and a barcode scanning component. The position sensing component is used to collect the position information of the items to be sorted on the accelerator belt 2. The main control module is used to control the barcode scanning component to scan the items to be sorted based on the position information of the items to be sorted on the accelerator belt 2 collected by the position sensing component, and to obtain the barcode data. The main control module is also used to determine the sorting channel 4 corresponding to the items to be sorted based on the barcode data, and to control the sorting host 3 to sort the items to be sorted to the sorting channel 4 corresponding to the items to be sorted based on the sorting channel 4 corresponding to the items to be sorted.

[0028] Specifically, the data acquisition module includes a first photoelectric sensor, a second photoelectric sensor, and a barcode scanner. The first photoelectric sensor is located at the end of the acceleration belt conveyor 2 near the alignment roller conveyor 1, and the second photoelectric sensor is located at the end of the acceleration belt conveyor 2 near the sorting host 3.

[0029] In some embodiments, the main control module is used to control the barcode scanning component to scan the items to be sorted on the accelerator belt 2 based on the position information of the items to be sorted collected by the position sensing component, including: When the first photoelectric sensor is triggered by the item to be sorted, the real-time transport speed of the accelerator belt 2 is obtained. Based on the real-time transport speed of the accelerator belt 2 and the trigger start time of the first photoelectric sensor, the predicted trigger time of the second photoelectric sensor is determined. Based on the predicted trigger time of the second photoelectric sensor, the scanning component is controlled to scan the items to be sorted.

[0030] In some embodiments, the main control module determines the predicted trigger time of the second photoelectric sensor based on the real-time conveying speed of the accelerator belt 2 and the trigger start time of the first photoelectric sensor, including: Obtain the distance between the first photoelectric sensor and the second photoelectric sensor; The transport time is calculated based on the distance between the first photoelectric sensor and the second photoelectric sensor, as well as the real-time transport speed of the accelerator belt 2. The predicted trigger time of the second photoelectric sensor is determined based on the trigger start time and transportation time of the first photoelectric sensor.

[0031] For example, the predicted trigger time of the second photoelectric sensor can be calculated using the following formula: in, The predicted trigger time for the second photoelectric sensor. The distance between the first photoelectric sensor and the second photoelectric sensor. To accelerate the real-time transport speed of belt conveyor 2, This is the trigger start time of the first photoelectric sensor.

[0032] For example, the distance between the first photoelectric sensor and the second photoelectric sensor is 500mm, and the real-time conveying speed of the accelerating belt conveyor 2 is 90m / min. Based on 500mm\90=0.33 seconds, the trigger start time of the first photoelectric sensor is determined to be 330ms after the trigger, which is when the second photoelectric sensor will arrive.

[0033] In some embodiments, the main control module controls the scanning component to scan the items to be sorted based on the predicted trigger time of the second photoelectric sensor, including: The trigger time range is determined based on the predicted trigger time of the second photoelectric sensor. For example, an initial time difference can be preset, and the predicted trigger time of the second photoelectric sensor minus the initial time difference can be used as the left endpoint of the trigger time range, while the predicted trigger time of the second photoelectric sensor plus the initial time difference can be used as the right endpoint of the trigger time range. When the second photoelectric sensor is triggered within the trigger time range, the scanning component is controlled to scan the items to be sorted.

[0034] Specifically, when the second photoelectric sensor is triggered within the trigger time range, the triggering of the first photoelectric sensor is determined to be valid, that is, the first photoelectric sensor is triggered by a real item to be sorted, thereby controlling the barcode scanning component to scan the item to be sorted.

[0035] The barcode scanning component can include a high-speed barcode reader to scan items to be sorted, ensuring a high success rate even during high-speed operation. It also stores images of unrecognized barcodes locally and performs targeted processing on these unrecognized barcodes, fundamentally solving recognition failure problems. For example, images of unrecognized barcodes can be manually reviewed or re-identified using more advanced image processing techniques. If the recognition failure is due to poor barcode quality (such as unclear printing or severe damage), the printing equipment or barcode generation parameters can be adjusted promptly. If the recognition failure is due to performance limitations of the scanning component itself, upgrading the scanning component or optimizing its decoding algorithm can be considered. Furthermore, by collecting a large number of barcode images of different types and qualities and labeling their correct decoding results, a highly efficient machine learning model can be trained. This model can be applied to the scanning component for fast and accurate recognition of unknown barcodes. Over time and with the accumulation of data, this model can continuously optimize and update itself.

[0036] The main control module will report the scanned data to the host system and store it in a container, awaiting instructions from the host system. Upon receiving the routing instruction from the host system, the main control module will combine the instruction with the scanned data into a string. Specifically, the main control module can parse the message instruction sent by the host system, extract the sorting channel 4 corresponding to the item to be sorted, and append the identifier of sorting channel 4 (e.g., "@", "^", "&", "*") to the task. This path identifier is added at the concatenation point in the original barcode transmission, reducing the amount of data transmitted while improving data stability.

[0037] In some embodiments, the sorting host 3 includes a sorting table, multiple sorting rollers and a swing adjustment component. The sorting rollers are partially embedded in the sorting table. The main control module is also used to adjust the rotation angle and rotation speed of each sorting roller through the swing adjustment component.

[0038] In some embodiments, the main control module adjusts the rotation angle and rotation speed of each sorting wheel via a swing adjustment component, including: Obtain the size and weight information of the items to be sorted; Based on the sorting channel 4 corresponding to the items to be sorted and the size and weight information of the items to be sorted, determine the optimal rotation angle and optimal rotation speed of each sorting wheel corresponding to the items to be sorted. Predict the end time of sorting the previous item to be sorted; At the predicted end time of the previous sorting item, the rotation angle and speed of each sorting wheel are adjusted according to the optimal rotation angle and speed of each sorting wheel corresponding to the item to be sorted.

[0039] By predicting the end time of the previous item to be sorted, the time when the previous item leaves the sorting host 3 is determined. When the sorting host 3 no longer needs to perform any oscillation action on the previous item, it begins to oscillate the next item to be sorted at the corresponding position. This ensures that the spacing between items to be sorted is reduced during the sorting process, achieving high-speed sorting.

[0040] As an example only, the optimal rotation angle and optimal rotation speed of each sorting wheel can be determined by the swing optimization model based on the sorting channel 4 corresponding to the item to be sorted and the size and weight information of the item to be sorted. The swing optimization model can be a convolutional neural network (CNN) model.

[0041] In some embodiments, the main control module obtains the size information of the items to be sorted, including: Obtain the trigger end time of the first photoelectric sensor corresponding to the item to be sorted; Based on the trigger start time of the first photoelectric sensor, the trigger end time of the first photoelectric sensor corresponding to the item to be sorted, and the real-time transport speed of the accelerator belt 2, the length of the item to be sorted is calculated, wherein the size information of the item to be sorted includes at least the length.

[0042] For example, the length of items to be sorted can be calculated using the following formula: in, The length of the items to be sorted. This refers to the trigger end time of the first photoelectric sensor corresponding to the item to be sorted.

[0043] A third photoelectric sensor is also installed on the sorting table.

[0044] In some embodiments, the main control module predicts the end time of the sorting of the previous item to be sorted, including: When the third photoelectric sensor is triggered by the item to be sorted, obtain the trigger start time of the third photoelectric sensor; Based on the length of the previous item to be sorted and the optimal rotation angle and optimal rotation speed of each sorting wheel corresponding to the previous item to be sorted, the sorting time required for the previous item to be sorted is predicted. Based on the trigger start time of the third photoelectric sensor and the sorting time required for the previous item to be sorted, the sorting end time of the previous item to be sorted is predicted.

[0045] For example, a time prediction model can be used to predict the time required to sort the previous item based on the length of the previous item and the optimal rotation angle and speed of each sorting wheel corresponding to the previous item. The time prediction model can be a convolutional neural network (CNN) model.

[0046] Each sorting channel 4 is also equipped with a fourth photoelectric sensor.

[0047] In some embodiments, the main control module is also used to verify the sorting channel 4 according to the sorting channel 4 corresponding to the item to be sorted when the fourth photoelectric sensor is triggered.

[0048] Specifically, when the second photoelectric sensor is triggered within the trigger time range, it can identify whether it is an item to be sorted, effectively identifying false triggers and reducing the number of false starts of the barcode scanning component. At the same time as the second photoelectric sensor is triggered, the main control module will send a barcode reading command to the barcode scanning component. At this time, the barcode scanning component will read the barcode, extract the barcode stored in the container based on the scan data, and parse the string corresponding to the sorting channel 4, thereby determining the sorting channel 4 corresponding to the item to be sorted. Based on the sorting channel 4 corresponding to the item to be sorted, the sorting host 3 controls the item to be sorted to the sorting channel 4 corresponding to the item to be sorted. When the fourth photoelectric sensor is triggered, it is determined whether the sorting channel 4 where the triggered fourth photoelectric sensor is located is consistent with the sorting channel 4 corresponding to the item to be sorted. If they are inconsistent, a sorting error is determined to have occurred, and a warning message is issued.

[0049] In some embodiments, the data acquisition module further includes a leveling roller conveyor status monitoring unit, an acceleration belt conveyor status monitoring unit, and a sorting host status monitoring unit. The leveling roller conveyor status monitoring unit is used to collect the status information of the leveling roller conveyor, the acceleration belt conveyor status monitoring unit is used to collect the status information of the acceleration belt conveyor 2, and the sorting host status monitoring unit is used to collect the status information of the sorting host 3.

[0050] As an example only, the status information of the alignment roller conveyor, the status information of the acceleration belt conveyor 2, and the status information of the sorting host 3 may include motor current, motor voltage, and motor torque, etc.

[0051] In some embodiments, the main control module is also used to perform fault diagnosis based on the status information of the alignment roller conveyor, the status information of the acceleration belt conveyor 2, and the status information of the sorting host 3.

[0052] For example, the main control module can perform fault diagnosis based on the status information of the alignment roller conveyor, the status information of the acceleration belt conveyor 2, and the status information of the sorting host 3 through the fault diagnosis model. The fault diagnosis model can be a Long Short-Term Memory (LSTM) network model.

[0053] When the front end of the equipment is damaged, the main control module can control the subsequent equipment to stop one level at a time, ensuring that the equipment is in a fully loaded state during the shutdown process, thus reducing the production pressure after recovery.

[0054] Finally, it should be understood that the embodiments described in this specification are merely illustrative of the principles of the embodiments described herein. Other variations may also fall within the scope of this specification. Therefore, alternative configurations of the embodiments described herein are intended to be illustrative rather than limiting, and should be considered consistent with the teachings of this specification. Accordingly, the embodiments described herein are not limited to those explicitly introduced and described herein.
