Description

Technical Field

[0001] This invention relates to the field of industrial robot control and intelligent logistics scheduling system technology, specifically to an intelligent scheduling system and method for an intelligent palletizing robot, and more particularly to an intelligent scheduling system and method for an intelligent palletizing robot for multi-specification flexible bulk materials. Background Technology

[0002] Existing tea product palletizing technologies mostly employ robots with fixed programs, which have the following core drawbacks:

[0003] 1. Poor specification adaptability: It can only adapt to a single packaging form, with a long changeover time, and cannot meet the needs of materials with multiple specifications such as tea powder and tea extract (e.g., The tea product industry faces the need for flexible production (including mixed packaging). Traditional equipment, due to its fixed mechanical structure, struggles to accommodate fluctuations in material specifications (such as packaging size deviations). ).

[0004] 2. Insufficient visual recognition accuracy: 2D visual positioning has large errors and cannot accurately identify the deformation characteristics of flexible bulk materials (such as the shape fluctuations of tea powder bags due to differences in filling amount), resulting in poor stacking stability (high collapse rate). In severe cases, this can lead to damage to the material packaging.

[0005] 3. Rigid scheduling strategy: The palletizing and warehousing processes are disconnected and not linked to the AGV logistics system, resulting in low equipment utilization. Traditional solutions lack dynamic scheduling models, leading to low warehouse space utilization and high material delivery delays.

[0006] Patent document CN220130470U discloses a tea-dried fruit stacking device for tea-dried fruit production and processing. Its workflow involves conveying the tea-dried fruit via a conveyor belt. During this process, the tea-dried fruit slides smoothly into a storage box on top of a weighing platform via a guide plate and a receiving plate. Once the weight of the tea-dried fruit reaches the set weight of the weighing platform, a first pusher plate pushes the storage box to the stacking platform. Then, a second pusher plate pushes the storage box inside the placement compartment to the top of the weighing platform for further packing. When the number of storage boxes at the stacking platform reaches three, it is pushed to the other end of the stacking platform. However, this patent document still fails to solve the aforementioned technical problem.

[0057] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0060] An intelligent scheduling system for an intelligent palletizing robot includes:

[0061] 3D dimension intelligent recognition module:

[0062] like Figure 2 As shown, the depth camera (positioning error) is installed on the right side of the gripping position. The robot's pneumatic gripper stroke (adjustment range) is dynamically adjusted based on the material density calculated in conjunction with its weight. ), achieving bag sizes from 30kg to 60kg, etc. Changeover without downtime for standard materials (changeover time) (minutes), material breakage rate is 0;

[0063] like Figure 3 As shown, this module takes point cloud data collected by a depth camera as input and achieves accurate extraction of the length, width, and height parameters of flexible materials through multi-step data processing:

[0064] 1. Point cloud preprocessing: The raw point cloud data is filtered for outliers. The Z-score algorithm is used to remove noise points that deviate from the mean by more than 3 times the standard deviation (such as redundant points caused by wrinkles on the material surface) to ensure data validity.

[0065] 2. Convex Hull Analysis: Project the preprocessed point cloud onto the XY plane to construct a convex hull model to fit the outer contour of the material. The material length (longest axis) is determined by calculating the maximum distance between the vertices of the convex hull, and the width (shortest axis) is calculated by the projection difference perpendicular to the direction of the longest axis, adapting to the irregular shape of flexible materials.

[0066] 3. Height Calculation: The maximum coordinate difference of the point cloud in the Z-axis direction is directly extracted to obtain the material height, avoiding measurement deviations caused by local protrusions;

[0067] 4. Output Results: The processed length, width, and height parameters are accurate to 1mm, providing basic data for subsequent processes.

[0068] Adaptive palletizing scheme generation module

[0069] like Figure 6 As shown, based on three-dimensional dimensional data and preset palletizing recipes (pallet length, width, and height limits), an optimal palletizing scheme is generated through an intelligent planning algorithm:

[0070] Parameter adaptation: Introduce a safety margin parameter (default 10mm) to correct the actual size of the material and avoid stacking interference caused by slight deformation of flexible materials;

[0071] Orientation optimization: Automatically simulates two placement orientations (original orientation and...) Calculate the number of materials that a single layer can hold (by dividing the pallet size by the corrected material size by an integer) for each rotation direction, and select the direction with the larger capacity as the optimal placement method;

[0072] Layer Calculation: Based on the ratio of the pallet height limit to the adjusted height of the material, combined with the maximum allowable layer threshold, determine the maximum number of stacking layers to ensure that the height limit is not exceeded;

[0073] Solution output: Generate a complete solution including placement direction, layout (number of rows and columns) of each layer, quantity of each layer, total number of layers, total capacity and distribution of remaining space, providing a basis for execution of automated palletizing equipment.

[0074] Material density estimation module

[0075] 1. By combining three-dimensional dimensions and weight data, rapid calculation of material density can be achieved:

[0076] 2. Volume Conversion: Convert length, width, and height parameters (in millimeters) to centimeters to calculate material volume (length...). Width high);

[0077] 3. Density Calculation: The density is obtained by using the ratio of weight (acquired by sensors) to volume. Density values ​​in units, accurate to [number] ;

[0078] Pneumatic gripper stroke adapter module

[0079] like Figure 7 and Figure 11 As shown, based on three-dimensional size and density data, the stroke parameters of the adapted pneumatic gripper are automatically calculated:

[0080] Reference selection: The maximum dimension in the length direction of the extracted material is used as the reference for the opening and closing of the grippers to ensure the maximum span of the covered material;

[0081] Safety redundancy: Based on the maximum size, a bidirectional safety margin is dynamically increased according to the density (the baseline is 10mm / side) to compensate for the shape changes when gripping flexible materials;

[0082] Stroke output: The calculation results are accurate to 0.1cm and are directly used as parameter inputs for the gripper control system to ensure gripping stability.

[0083] WMS storage scheduling module based on shape detection

[0084] like Figure 12 As shown, available storage space data is obtained through the WMS interface, and a standardized model is established, including storage space code, region, floor height, size restrictions, and access priority. Using the length, width, and height of the goods obtained from shape detection as input, safety margin parameters (height 10mm, length and width 10mm) are introduced to correct for actual needs, and candidate storage spaces with suitable sizes are selected from the available storage spaces.

[0085] like Figure 4 As shown, a "palletizing posture - storage height" matching algorithm is constructed. The AGV uses the incoming shape detection data (height recognition accuracy) to determine the appropriate height. Automatic delivery to suitable storage locations increases warehouse space utilization. Equipment utilization rate increased to This addresses the issues of slow shape change, high breakage rate, and inefficient scheduling in the palletizing process for flexible bulk materials such as tea.

[0086] A two-layer optimization algorithm is used to select the optimal storage location: first, storage locations are sorted according to the constraints of the storage location group, with higher priority locations given priority; then, the height utilization rate is calculated, and the storage location that best matches the height requirements of the goods is selected to reduce space waste. Finally, storage location allocation instructions are issued through the WMS interface, and scheduling results containing storage location information are returned, realizing an automated closed loop from appearance detection to warehousing.

[0087] The modules form a closed loop through data chain transmission: 3D dimension recognition provides basic parameters for all subsequent modules; palletizing scheme generation relies on accurate dimensional data to achieve spatial optimization; density estimation combines size and weight to achieve material characteristic analysis; gripper stroke calculation based on dimensional data ensures gripping reliability; storage location scheduling selects appropriate shape detection schemes based on dimensional calculations and performs transportation scheduling based on shape detection results. The system coordinates the timing of each module through unified control logic, achieving full automation from material identification to warehousing processing execution. It is suitable for scenarios such as logistics sorting, warehouse palletizing, and flexible manufacturing, significantly improving processing efficiency and adaptation accuracy.

[0088] As shown in Table 1, the system components also include:

[0089] Table 1 Components and their corresponding functions

[0090]

[0091] like Figure 5 As shown, the data acquisition platform also adopts the industry-standard industrial control data transmission protocol, which is then encapsulated into an IoT platform. This platform adds features such as device connection configuration management, acquisition attribute group management, and acquisition attribute configuration, making it an infrastructure platform. The IoT platform facilitates the interactive control between the WMS software system and the equipment automation control system.

[0092] The IoT platform is used to access the internal resources of the PLC, including:

[0093] Read and write the status of input / output (I / O) points;

[0094] Read and write data in memory areas (such as the M area and DB area);

[0095] Obtain PLC operating status and fault information;

[0096] Remote control of PLC (such as starting and stopping).

[0097] Example 2

[0098] The system mentioned above includes three operating modes: automatic palletizing and warehousing of raw materials, manual palletizing and warehousing, and palletized warehousing. Operators can select the corresponding production mode and configure material information on the interface (or receive it from the WMS).

[0099] like Figure 8 and Figure 9 As shown, an intelligent scheduling method for an intelligent palletizing robot includes:

[0100] Step 1: Empty pallet groups / empty pallets are put into the online empty pallet loading point, enter the pallet depalletizer to be broken into individual pallets and supplied to the automatic palletizing station, where the pallet barcode information is scanned;

[0101] Step 2: Raw materials are fed from the right telescopic belt conveyor and stop at the automatic palletizing station to wait for the robotic arm to grab them;

[0102] Step 3: Capture the position signal to trigger the change judgment. After the change judgment, visually identify the length, width and height information of the goods and output it to the automatic control program.

[0103] Step 4: The automated control program calculates the material density based on visual recognition information and weight, and adds pneumatic gripper stroke control parameters to the palletizing scheme specified in the formula.

[0104] Step 5: The robotic arm grabs the raw materials and stacks them onto the pallet according to the gripping stroke and palletizing plan provided by the upper-level information system;

[0105] Step 6: After the raw material robot completes the palletizing, the system will bundle the pallet barcode information and the palletized raw material information and upload them to the WMS.

[0106] like Figure 10 As shown in step 7, the WMS matches the appropriate storage location group according to the height of the cargo location and initiates a logistics scheduling instruction; after the AGV arrives at the location and connects, the AGV is scheduled to transport the cargo to the high / medium / low storage location in the warehouse area.
