Automatic weighing and counting distributed sorting system for light and small parts based on non-physical calibration

Abstract

The invention provides an automatic weighing and counting light and small piece distributed sorting system based on non-object calibration, which comprises a three-dimensional goods shelf comprising a plurality of groups of material positions, each group of material positions at least comprises a material supplementing position and a material taking position, the material supplementing position is provided with a material conveying device used for conveying materials from the material supplementing position to the material taking position, and the material conveying device is used for conveying the materials from the material supplementing position to the material taking position; the material taking position is provided with a non-real-object calibration measuring weighing apparatus, and the three-dimensional goods shelf is provided with a state indicating lamp and a material supplementing indicating lamp. The material supplementing module is connected with the material-object-calibration-free measuring weighing apparatus so as to receive the material weight data collected by the material-object-calibration-free measuring weighing apparatus, generate a material supplementing signal based on the received material weight data and transmit the material supplementing signal to the WMS system; and the monitoring service module is connected with the material supplementing module, the material supplementing indicating lamp and the state indicating lamp, and the monitoring service module is used for receiving a material supplementing signal generated by the material supplementing module. According to the system, high efficiency and orderliness of the sorting process of the light and small materials are ensured, and the sorting cost of the light and small materials is reduced.

Description

technical field [0001] The invention relates to the technical field of material picking, in particular to a distributed picking system based on automatic weighing and counting of light and small pieces without physical calibration. Background technique [0002] Due to the normalization of the global outbreak of the new crown pneumonia epidemic, factories in many countries and regions are facing the risk of not being able to operate at any time, and China has the most effective control of the epidemic, so the proportion of China's global industrial orders has increased significantly, while most industrial production Light and small mechanical parts and electronic components are inseparable. However, due to the small size of light and small parts, complex specifications and models, strong professionalism, and difficulty in marking and measuring, in the process of entering and leaving the storage of light and small parts, in order to ensure the number of models of the parts Mat...

Problems solved by technology

[0002] Due to the normalization of the global outbreak of the new crown pneumonia epidemic, factories in many countries and regions are facing the risk of being unable to start work at any time, and because China is the most effective in controlling the epidemic, the proportion of China's global industrial orders has increased significantly, and most of the industrial production It is inseparable from light and small mechanical parts and electronic components. However, due to the characteristics of small size, complex specifications and models, strong professionalism, and difficult identification and measurement of light and small parts, in the process of entering and leaving the warehouse, in order to ensure the model quantity of parts Matching requires complex processes and more manpower to ensure the accurate entry and exit of light and small parts. At present, the technical solution generally adopted is similar to the patent No. CN202010999070.8 titled "a three-dimensional storage system and method for parts storage". Technical solutions

[0003] Currently, the commonly used scheme above adopts the physical isolation of inbound and outbound warehouses, and manages the inbound and outbound warehouses of light and small parts by means of multi-manual hand-held scanning. A stacker is required between the warehouse and the warehouse for handling, and manual hand-held terminals are used to scan RFID for picking. Therefore, it takes a long time to go through a complete set of light and small pieces picking process, which makes the time for materials entering and leaving the warehouse long and increases The time cost of the entire light and small item picking process is reduced; and the human-computer interaction of the solution is not friendly, and it is easy to cause management confusion in the actual application process

[0004] In addition, in order to judge whether the quantity of the selected materials meets the demand, the materials are generally weighed during the picking process. However, due to the small weight of light and small items, the requirements for weighing accuracy are very strict, so the weighing equipment must be checked frequently. Calibration; while the traditional weighing calibration method is based on physical calibration, the use of the shelf must be stopped during the calibration process, resulting in a decline in overall picking efficiency and increasing labor costs and time costs
