The main difference between automatic checkweigher and static scale
Before using the automatic checkweigher, the measurement of the product weight usually uses a static scale. The product is manually weighed on the table of the static scale, and then manually sorted or rejected according to the measured weight. The main differences between manual weighing of static scales and automatic weighing of automatic checkweighers are: 1) Jingzhi scales measure the static weight of products, while most automatic checkweighers measure the dynamic weight of products in motion (even if there are very few The automatic checkweigher machine adopts a relatively static weighing process, but the relatively static time is also very short). 2) The static scale weighing is manual operation, and the product needs to be manually weighed on the carrier, and then the product is removed to prepare for the next product weighing. The checkweighing section is completely automatic, and when the product passes along the production line, it is weighed without manual intervention or a dedicated operator. 3) The sorting of products or unqualified products by static scale is manual operation, which will inevitably make mistakes. The corresponding operation of the automatic checkweigher is automatically carried out by the weighing display control device, with high accuracy. 4) The working efficiency of static scales is very low, so for large quantities of products, a certain proportion of samples (such as 1% or less) are usually taken manually and weighed on-site, while the proportion of automatic checkweighers to automatically check the factory products is 100%. 5) Static scale weighing has higher accuracy and better repeatability, while the accuracy and repeatability of automatic checkweigher machine is slightly worse. 6) Jingzhike weighing with recorded data requires manual handwritten records, while the Checkweighing Section can automatically record the data and classify and summarize it to realize big data management. It can also realize the feedback of the filling amount of the charging machine through the product weighting data. control. Among the above differences, 10% product inspection of the d-state checkweigh bar is not critical to ensuring product quality. Take a production line with a throughput of 100 products per minute as an example. Section, the sampling rate is only: 30+(100X60)u003d0.5%. Such a low sampling rate is of little significance to the statistical analysis of results application experience, and it is also difficult to guarantee the quality of the remaining 99.5% of the products. The above is the main difference between the automatic checkweigher and the static scale for everyone to share.
