However, these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present application is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and thus their description will be omitted.

[0037] In combination with Figure 1As shown, according to a specific embodiment of the present application, a frame offline system with a multi-level frame area is provided, including: a sorting buffer device, which includes a first conveyor belt 1, a pose control component, and a frame sorting detection component 8. A first frame area 3 is formed at the top of the first conveyor belt 1. Both the pose control component and the frame sorting detection component 8 are connected to the first conveyor belt 1. The pose control component is used to detect and adjust the pose of the frames to be taken offline in the first frame area 3, and the frame sorting detection component 8 has a working state of detecting the categories of the frames in the first frame area 3; a scheduling device, which includes a second conveyor belt 4 and a frame sorting execution component 6. The second conveyor belt 4 is located on the downstream side of the first conveyor belt 1. A second frame area 7 is formed at the top of the second conveyor belt 4. The second conveyor belt 4 has a plurality of transfer outlets 5, and different transfer outlets 5 are respectively close to different logistics transportation devices. The frame sorting execution component 6 is connected to the second conveyor belt 4, and the frame sorting execution component 6 is used to drive the frames in the second frame area 7 to be transferred to different transfer outlets 5 according to the detection results of the frame sorting detection component 8.

[0038] Applying the technical solution of the present invention, a first frame area 3 is formed at the top of the first conveyor belt 1. The frame offline system first controls the pose of the frames in the first frame area 3 and detects their categories, and then uses the frame sorting execution component 6 in the second frame area 7 for sorting and taking offline, realizing the automatic offline and classification of the empty return frames, and at the same time avoiding the problem of large space occupation of the frames caused by non-standardized manual operations. By adopting the technical solution of the present application, the problem that the empty return frames in the prior art need to be manually carried and classified is effectively solved.

[0039] The multi-level frame system can significantly improve the efficiency and flexibility of logistics processing, realize more refined frame classification and scheduling, further shorten the production cycle, and reduce the logistics cost.

[0040] Optionally, the first conveyor belt and the second conveyor belt can also be replaced by guide rails.

[0041] By adopting the technical solution of the present application, the problems in the prior art that the empty return frames need to be manually carried and classified, the automation degree is low, the efficiency is not high, and there are safety hazards and the problems of frame stacking and large storage space occupation caused by non-standardized manual operations are solved. The following technical effects are achieved by this solution:

[0042] 1. Automation improvement: Realize the automatic offline and classification of the empty return frames, reduce manual intervention, and improve the operation efficiency and safety.

[0043] 2. Space optimization: Avoid the problem of large space occupation of the frames caused by non-standardized operations, and optimize the space utilization of the warehouse and the production line.

[0044] 3. Process Optimization: The transfer process of the cargo frame from the production line to the logistics transportation equipment has been optimized through intelligent control and automated equipment, shortening the production cycle.

[0045] Furthermore, the cargo frame offline system includes a controller, and the pose control component includes:

[0046] An optoelectronic sensor 21, which is connected to the first conveyor belt 1 and is used to detect the position and pose of the cargo frame;

[0047] A fork 22, which is connected to the first conveyor belt 1;

[0048] Among them, the controller is electrically connected to both the optoelectronic sensor 21 and the first conveyor belt 1, and the controller is used to control the working parameters of the fork 22 according to the detection signal of the optoelectronic sensor 21.

[0049] The optoelectronic sensor 21 detects the position and pose of the cargo frame to ensure the correct placement of the cargo frame on the first cargo frame area 3. The controller accurately controls the working parameters of the fork 22, such as speed, direction, and force, according to the detection signal of the optoelectronic sensor 21, so as to automatically adjust the pose of the cargo frame to meet the requirements of subsequent processes. This avoids the inaccuracy and low efficiency of manual adjustment.

[0050] By accurately controlling the pose of the cargo frame, it is ensured that the cargo frame can be accurately detected and classified by the cargo frame classification and detection component 8 on the second conveyor belt 4, thereby improving the sorting accuracy of the entire cargo frame offline system.

[0051] The real-time detection ability of the optoelectronic sensor 21 and the intelligent analysis ability of the controller can timely detect abnormal poses of the cargo frame. Through the adjustment of the fork 22, the collision or jamming of the cargo frame during the transmission process is reduced, enhancing the stability and safety of the system.

[0052] Automated pose adjustment reduces the hard collision between equipment, reduces equipment wear, and indirectly reduces the frequency and cost of maintenance and repair.

[0053] The automated adjustment and classification of the cargo frame shorten the residence time of the cargo frame on the production line, speed up the logistics turnover, and improve the overall efficiency of the production line.

[0054] Optionally, in addition to the optoelectronic sensor 21, ultrasonic sensors, pressure sensors, or infrared sensors can be added for multi-dimensional information collection to enhance the accuracy and reliability of the cargo frame pose control. For example, ultrasonic sensors can be used to detect the distance between cargo frames to avoid collisions; pressure sensors can detect the weight of the cargo frame to help adjust the thrust of the fork 22.

[0055] Optionally, the fork 22 can be designed as an adaptive fork, which automatically adjusts its shape and contact points according to the detected size and shape of the cargo box through a built-in intelligent algorithm to adapt to different types of cargo boxes. In addition, it can be considered to add a soft material covering on the fork 22 to reduce damage when contacting the cargo box.

[0056] The controller can integrate machine learning algorithms to learn how to more efficiently adjust the pose of the cargo box based on historical data. For example, by analyzing the optimal poses of different types of cargo boxes on the conveyor belt, the parameters of the photoelectric sensor 21 and the fork 22 are dynamically adjusted to improve the overall performance of the system.

[0057] Furthermore, the cargo box classification and detection component 8 includes a weight sensor and / or a size scanning device.

[0058] In an optional embodiment, there are multiple intelligent sensors on the guide rail or conveyor belt in the cargo box area, including but not limited to weight sensors, pressure sensors, and displacement sensors, which are used to monitor the load, contact pressure, and position changes of the cargo box in real time. Combining with the processing ability of the PLC, the working state of the drive system is adaptively adjusted according to the monitored parameters, such as the thrust of the cylinder, the grasping force of the pawl, and the speed of the conveyor belt.

[0059] The data of each intelligent sensor will be transmitted to the PLC in real time, and the PLC analyzes the data through a preset algorithm model and automatically adjusts the parameters of the drive system. For example, when it is detected that the weight of the cargo box is large, the thrust of the cylinder will be automatically increased to ensure the stability of the movement of the cargo box.

[0060] Through intelligent sensing and adaptive adjustment, the system can better adapt to the handling of cargo boxes under different conditions, reduce mechanical damage, and improve the accuracy and safety of logistics operations.

[0061] Furthermore, the cargo box classification and detection component 8 includes an image feature recognition instrument, which is used to recognize the barcodes and / or QR codes on the cargo box and determine the category of the cargo box according to the recognition results.

[0062] In an optional embodiment, the image feature recognition instrument includes a high-resolution industrial camera, which is used to capture barcodes, QR codes, or specific image features on the cargo box. Combining image processing and pattern recognition technologies, rapid and accurate recognition of the cargo box is achieved.

[0063] The vision system transmits the captured image data to the PLC in real time. The PLC identifies the type and status of the cargo box through a preset image recognition algorithm, and then conducts classification and scheduling control of the cargo box according to the recognition results.

[0064] The integrated vision system can significantly improve the accuracy and speed of cargo box recognition, ensure that the cargo boxes are correctly processed and scheduled, reduce errors in logistics operations, and enhance the overall performance of the logistics automation system.

[0065] In another alternative embodiment, each cargo box is embedded with an RFID (Radio Frequency Identification) tag, which stores information such as the unique identification code, type, and weight of the cargo box. RFID readers are installed at key positions in the first cargo box area and on the AGV carts. Through the wireless communication between the RFID reader and the tag, remote identification and control of the cargo box are achieved.

[0066] When the cargo box enters the first cargo box area, the RFID reader reads the tag information on the cargo box and transmits the information to the PLC. The PLC automatically identifies the cargo box based on the received information and performs corresponding processing, such as scheduling it to a specified AGV cart. At the same time, the RFID system can update the position information of the cargo box in real time, facilitating logistics tracking and scheduling.

[0067] By combining embedded electronic tags with wireless communication, the logistics automation system can achieve real-time and remote identification and control of cargo boxes, improve the intelligent level of logistics scheduling, reduce manual intervention, and enhance the efficiency and accuracy of logistics operations.

[0068] Furthermore, the second conveyor belt 4 has a belt body, a driving motor 2, and a support frame. The belt body is slidably connected to the support frame, the driving motor 2 is connected to the support frame, and the driving motor 2 is used to drive the belt body to move. The support frame is arranged such that its horizontal inclination angle relative to the horizontal plane is adjustable. The cargo box offline system further includes a conveyor belt control device, which is electrically connected to the cargo box classification detection component 8. The conveyor belt control device is used to adjust the rotation speed of the driving motor 2 and the horizontal inclination angle of the support frame according to the detection result of the cargo box classification detection component 8.

[0069] The support structure of the conveyor belt has an adjustable tilting device, usually composed of a hinge mechanism driven by a hydraulic cylinder, a cylinder, or a motor. By sending instructions through the PLC or the control system, the driving device is controlled to tilt the support frame of the conveyor belt within a certain range, thereby changing the angle of the conveyor belt. Alternatively, the conveyor belt has a variable-angle guide rail system, which can support the conveyor belt to slide along the guide rail, and the angle of the guide rail can be adjusted. Through a mechanical link mechanism or an electrically driven guide rail adjustment device, the PLC or the control system can adjust the angle of the guide rail as needed, thereby changing the running direction of the conveyor belt. Alternatively, the conveyor belt is of a segmented design, and each segment of the conveyor belt is connected by an adjustable-angle transition section. The transition section can be a movable joint or a transition platform with a variable angle. By adjusting the angle of the transition section, the running direction and angle of the entire conveyor belt system can be changed.

[0070] The intelligent angle adjustment system combines sensors (such as angle sensors) and PLC control to detect the inclination angle of the conveyor belt in real time. The PLC can automatically adjust the drive device according to the feedback data of the sensors (the detection results of the frame classification detection component 8) and the preset logistics requirements, so that the conveyor belt reaches the ideal inclination angle. On the one hand, it protects the frames, and on the other hand, it improves the transportation efficiency and ensures their safe movement at a specific angle.

[0071] Optionally, the conveyor belt is provided with side guards, material pressing devices, etc. to prevent materials from sliding or shifting at the inclination angle.

[0072] Further, the frame classification execution component 6 includes a plurality of push-pull cylinders, which are arranged in one-to-one correspondence with a plurality of transfer outlets 5. The movement stroke of the push-pull cylinders is variably set, and the push-pull cylinders are used to push the corresponding frames from the second frame area to the corresponding transfer outlets 5.

[0073] The precise movement of the push-pull cylinders can achieve precise control of the frame position, ensure that the frames are accurately pushed to the designated transfer outlets, and improve the accuracy and efficiency of sorting.

[0074] Since the movement stroke of the push-pull cylinders is variable, it can adapt to frames of different sizes and dynamic sorting requirements, enhancing the flexibility of the system and the handling ability for multiple types of frames.

[0075] Compared with traditional mechanical drive devices, the push-pull cylinders can move the frames more smoothly and safely, reducing the risk of damage to the frames and goods caused by violent collisions, and at the same time reducing the safety hazards for operators.

[0076] The cylinder structure is simple and easy to maintain. Compared with complex robotic arm structures, its maintenance and replacement costs are lower.

[0077] Further, there is even an elastic baffle at the side wall of the transfer outlet 5. The elastic baffle has a guiding profile and is used to reduce the impact force when the frame reaches the transfer outlet 5.

[0078] The elastic baffle can effectively absorb and buffer the impact force when the frame reaches the transfer outlet, avoid damage to the frame and goods due to collision, and improve the integrity and service life of the frame.

[0079] The guiding profile of the baffle helps to guide the frame to smoothly enter the transfer outlet, reduce jamming or collision caused by position deviation, and ensure the continuity and efficiency of the sorting process.

[0080] The use of elastic materials can significantly reduce the noise generated when the frame collides with the baffle, improve the working environment, and reduce interference to operators.

[0081] The surface of the baffle can be designed with a self-cleaning structure, such as using hydrophobic or oleophobic materials, or designing a micro-nano surface structure to reduce the adhesion of materials on the surface of the cargo frame and lower the maintenance and cleaning costs.

[0082] Further, the cargo frame offline system includes a door device 9, which is arranged on the first conveyor belt 1, and the door device 9 has a working position for stopping the cargo frame on the first conveyor belt 1.

[0083] Further, the door device 9 includes a driving cylinder and a door body. The driving cylinder is used to drive the door body to move in a direction perpendicular to the first conveyor belt 1, and the door body is located on top of the first conveyor belt 1.

[0084] The door device 9 can also directly use a cylinder.

[0085] Further, the cargo frame offline system further includes:

[0086] A receiving device, which includes a receiving conveyor belt. One end of the receiving conveyor belt is arranged close to the production line, and the other end of the receiving conveyor belt is located on the upstream side of the first conveyor belt 1.

[0087] That is to say, the applied cargo frame offline system is an automatic push-pull mechanism composed of three-level cargo frame areas, namely a receiving area, a sorting buffer area, and a scheduling area. The receiving area is responsible for directly receiving the cargo frame from the production line; the sorting buffer area conducts preliminary sorting according to the type, size, or destination of the cargo frame; the scheduling area then schedules the cargo frame to the corresponding AGV cart or other logistics equipment through the corresponding exit according to the real-time logistics demand and the availability of the AGV cart.

[0088] Optionally, photoelectric sensors are arranged at the entrance and exit positions of each cargo frame area to detect the position and status of the cargo frame. At the same time, a weight sensor and a size scanner are used for accurate identification of the cargo frame in the sorting buffer area. Through the intelligent control algorithm of the PLC, the automatic scheduling of the cargo frame in the multi-level cargo frame system is realized.

[0089] Optionally, a fault detection function is integrated into the system. In the case of a situation such as a frame blockage or incorrect sorting to the designated exit, the PLC can detect and process the abnormality in real time according to the sensor data.

[0090] Through the intelligent calculation of the PLC, if sorting errors or low efficiency are found, parameters can be automatically adjusted, such as adjusting the thrust of the cylinder, the grasping force of the pawl, or the angle of the guide rail, etc., to optimize the sorting process.

[0091] Adopting the technical solution of this application can be applied to the field of logistics automation technology. Specifically, an automatic push-pull mechanism based on photoelectric sensors and PLC is provided, which is suitable for the scenario of the offline of the in-line cargo frame on the production line. During the process of the in-line cargo frame returning empty and going offline, the application of the automatic push-pull mechanism is involved. Its main function is to automatically connect the cargo frame and place it on logistics equipment such as AGVs.

[0092] In an optional embodiment, the system includes a learning module. The learning module uses deep learning technology and combines with a vision sensor to achieve high-precision recognition of complex patterns and markings on the cargo frame, and can accurately classify the cargo frame even during high-speed transmission, improving the intelligent processing ability of the system.

[0093] Optionally, the cargo frame classification and detection component can be equipped with an adjustable sensor array, which automatically adjusts the detection range and accuracy according to different cargo frame specifications, such as by adjusting the sensitivity of the weight sensor or the scanning distance and resolution of the size scanning device.

[0094] Optionally, a movable image feature recognition instrument is designed, and the recognition instrument can be adapted to cargo frames of different sizes and shapes through a rail system or a robotic arm, improving the flexibility and adaptability of classification.

[0095] Optionally, the cargo frame offline system is integrated with Internet of Things technology. Each cargo frame is equipped with an RFID or wireless Bluetooth tag, enabling it to communicate with the central control system or other logistics equipment (such as an AGV car) in real time, realizing precise tracking and scheduling of the cargo frame.

[0096] Optionally, through the Internet of Things, the system can monitor the status of logistics equipment in real time, such as the battery power, position, and load capacity of an AGV car, so as to intelligently schedule the offline and transportation of the cargo frame.

[0097] The first conveyor belt and the second conveyor belt serve as guiding lanes for the cargo frame, which are used to fix the running direction of the cargo frame, guide the materials to move along a predetermined direction, and prevent deviation or jamming. A reduction motor and the like provide power for the lanes. Figure 1 The PLC control system 100 and the second door body 101 are also shown. The second door body 101 can be a cylinder, which is responsible for whether the second cargo frame area is opened. The PLC control system 100 monitors and adjusts the operation of the lanes. The PLC forms the logical control core. The AGV car is responsible for towing the cargo frame out of the cargo frame area.

[0098] In an alternative embodiment, the control flow of the system may be as follows: Detect whether there is a cargo box (and the type of the cargo box) in the first cargo box area and whether the cargo box reaches the standard position through a photoelectric sensor. If it reaches the standard position, the first-stage cylinder opens for release, and the PLC controls the power device to push the cargo box into the designated position in the second cargo box area. After the cargo box enters the second cargo box area, if the photoelectric signal in the first cargo box area detects that the area is empty, the door device is automatically closed. The photoelectric sensor in the second cargo box area sorts to different exits, or detects whether the cargo box in this area is full. If it is full, the second door 101 opens to release the AGV cart to tow the cargo box out of the cargo box area. Through the technical solution of this embodiment, the following technical effects are achieved:

[0099] 1. Improve efficiency, reduce manual handling, and significantly enhance the conveying efficiency. It can operate continuously for 24 hours to further improve efficiency.

[0100] 2. Fast and accurate: Precise positioning and fast conveying, shortening the production cycle.

[0101] 3. Reduce costs: Automated operation reduces the need for labor, lowering labor costs. Reduce damage to materials during handling, reducing loss costs.

[0102] 4. Improve accuracy: The guiding device ensures that the materials reach the designated position accurately, reducing errors. Reduce mistakes: The automated system reduces human errors and improves operation accuracy.

[0103] 5. Enhance flexibility: It can be flexibly designed with a linear, curved or spiral layout according to site conditions. Easy to expand: The length and quantity of the cargo lanes can be expanded or adjusted according to production requirements.

[0105] Improve efficiency: Realize the automated flow of materials, reduce manual handling, and enhance efficiency.

[0106] Reduce costs: Reduce the use of packaging materials and lower logistics costs.

[0107] Reduce losses: Protect materials from being damaged during transportation.
