Description

Technical Field

[0001] The present invention relates to the technical field of logistics automation, and in particular to an Internet-based material sorting management system and method. Background Art

[0002] Material sorting refers to the process of classifying, sorting, and accurately allocating mixed materials to corresponding locations in the fields of logistics, manufacturing, etc., based on different attributes such as material type, specification, destination, order requirements, etc. This process is widely used in various warehouses, distribution centers, factory production lines, etc., and is a key link in achieving efficient material circulation and accurate supply.

[0003] In recent years, with the popularization of Internet technology and the booming development of e-commerce, online shopping has become one of the mainstream consumption methods, and the volume of express delivery business has grown exponentially. Massive orders require logistics companies to complete the sorting and delivery of a large number of materials (commodity packages) in a short period of time. Traditional manual sorting methods cannot bear such a huge workload and timeliness requirements, and more efficient and intelligent sorting solutions are urgently needed. Modern manufacturing is developing in the direction of refinement and flexibility, and the accuracy and timeliness of the supply of parts in the product production process are extremely high. On complex production lines, parts of different models and specifications need to be accurately sorted and transported to the corresponding production stations to ensure production continuity and product quality. This has prompted companies to introduce advanced material sorting technology and equipment. With the development of the economy, labor costs continue to rise. At the same time, the labor force willing to engage in high-intensity and repetitive sorting work is gradually decreasing. Companies are facing the pressure of labor costs and the problem of difficulty in recruiting workers. In order to reduce operating costs and improve production efficiency, companies have begun to seek automated and intelligent material sorting methods to replace manual operations.

[0004] The grabbing device is an important structural component in the material sorting management system. Due to technical limitations or equipment design defects, it is impossible to accurately evaluate the working capacity of the grabbing device, which can easily lead to the problem of materials falling when grabbing materials, increasing the risk of material damage and loss, and increasing costs. In addition, when the grabbing device is working, it is difficult to accurately predict the working condition of the grabbing device, resulting in untimely fault discovery and increased risk of material falling and damage. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an Internet-based material sorting management system and method, which has the advantages of combining multiple data to evaluate the working ability of the grasping device for the current material, avoiding the situation where the material falls during the grasping process and thereby damaging the material.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-Figure 2 , a material sorting management system based on the Internet, including a monitoring module, an analysis module, an adjustment module and a feedback module;

[0040] The monitoring module is used to obtain the physical characteristics of the current material and the parameters of the current gripping device, and to form a material physical characteristic data set in combination with the physical characteristics of the current material, and to form a current device parameter set in combination with the parameters of the current gripping device, and to send the collected material physical characteristic data set and current device parameter set to the analysis module;

[0041] The material physical characteristic data set is: {WLzl, WLmc}, where WLzl represents the material weight data, and WLmc represents the material friction. The material weight data and the material friction are both key factors affecting the material grasping process. Through these two factors, the material grasping force can be accurately evaluated;

[0042] The current device parameter set is: {XNcs, ZTcs}, where XNcs represents performance parameters and ZTcs represents status parameters. The performance parameters in the current device parameter set include: pressure value YLsj, current value DLsj, voltage value DYsj, and temperature value WDsj. Performance parameters can reflect the working status of the grabbing device. By monitoring these data, the working status of the device can be accurately evaluated, the working status of the device can be grasped in real time, and abnormalities of the device can be discovered in time to ensure the normal operation of the device.

[0043] The status parameters in the current equipment parameter set include the number of grippers JZsl and the gripping force JQl. The status parameters are key factors in the gripping process of the gripping device. The gripping force of the gripping device can be evaluated through the status parameters, and whether the gripping device meets the gripping requirements can be accurately analyzed;

[0044] The analysis module calculates the material grabbing demand force based on the material physical characteristic data set, calculates the current equipment actual grabbing force and the current equipment failure index based on the current equipment parameter set, and calculates the grabbing difference value based on the material grabbing demand force and the current equipment actual grabbing force. Based on the grabbing difference value, it determines whether the current grabbing device can grab the current material. The analysis module also determines whether the current grabbing device is faulty based on the current equipment failure index.

[0045] The specific formula of material grabbing demand force WLzq is as follows:

[0046]

[0047] In the calculation formula, WLzq represents the required force for material grabbing, μ represents the friction coefficient between the gripper and the material, K represents the safety factor, g represents the acceleration of gravity, and a represents the acceleration during the grabbing process. By combining multiple parameters, the required grabbing force for the material can be accurately calculated, reflecting the demand for the material to be grabbed, and providing a basis for the judgment of material grabbing;

[0048] The specific formula of the actual grasping force SBzq of the current equipment is as follows:

[0049]

[0050] In the calculation formula, SBzq represents the actual gripping force of the current equipment, μ represents the friction coefficient between the gripper and the material, K represents the safety factor, g represents the acceleration of gravity, and a represents the acceleration during the gripping process. It indicates the coefficient of dynamic force, reflecting the additional load caused by acceleration during the grasping process. By combining multiple parameters, the maximum mass that the grasping device can grasp can be accurately calculated, reflecting the grasping capacity of the grasping device, and providing a basis for judging whether the device can grasp the material.

[0051] The specific formula of the current equipment failure index SBjk is as follows:

[0052]

[0053] In the calculation formula, SBjk represents the current equipment failure index, RYLsj, RDLsj, RDYsj, and RWDsj represent the standard values ​​of pressure, current, voltage, and temperature, respectively. They respectively represent the ratios between the pressure value, current value, voltage value, and temperature value and the standard value. α1, α2, α3, and α4 respectively represent the influence weights of the differences between the pressure value, current value, voltage value, and temperature value and the standard value. Combining multiple indicators of pressure value, current value, voltage value, and temperature value, it is possible to timely capture subtle changes in equipment operating parameters, discover potential problems before obvious equipment failures occur, prevent the failures from expanding, protect the entire equipment system, and maintain the equipment in a good operating state, which can effectively extend the service life of the equipment, reduce the frequency of equipment replacement, and reduce the equipment investment cost of the enterprise.

[0054] The specific formula for grabbing the difference value ZQcd is as follows:

[0055] ZQcd=SBzq-WLzq

[0056] In the calculation formula, ZQcd represents the gripping difference value, which directly reflects the working ability of the gripping equipment for the current material;

[0057] When the grab difference value ZQcd is less than 0, the current grabbing device cannot grab the current material;

[0058] When the current device fault index SBjk is greater than the device fault index threshold, the current grasping device is faulty;

[0059] When the analysis module determines that the current grabbing device cannot grab the current material, it sends an adjustment signal to the adjustment module. When it determines that the current grabbing device fails, it sends a fault signal to the feedback module.

[0060] When receiving the adjustment signal, the adjustment module adjusts the gripping force of the gripping device, such as increasing the power output and adjusting the gripping structure, thereby improving the gripping force, so that the gripping device can meet different degrees of gripping requirements and avoid the material from falling and damaging the material during the gripping process;

[0061] When the feedback module receives a fault signal, it sends a fault alarm signal to the staff, so that the staff can carry out timely maintenance and avoid serious equipment failures that affect operational needs.

[0062] The specific method of the above-mentioned Internet-based material sorting management system is as follows:

[0063] Step 1: Obtain the physical characteristics of the current material to form a material physical characteristics data set;

[0064] Step 2: Obtain the parameters of the current grabbing device to form a current device parameter set;

[0065] Step 3: Calculate the material grabbing demand force, the actual grabbing force of the current equipment, the current equipment failure index and the grabbing difference value according to the material physical characteristic data set and the current equipment parameter set;

[0066] Step 4: Determine whether the current grabbing device can grab the current material and whether the current grabbing device is faulty by using the grabbing difference value and the current device fault index;

[0067] Step 5: Respond based on the judgment result.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
