What are the advantages of automatic weighing machines? How to use automatic weighing machine correctly
Automatic weighing machine is a kind of assembly line automatic weighing equipment, which can detect the weight of products with high precision and high speed. Do you know how to use the weighing machine? What are the advantages of the automatic weighing machine and how to distinguish the weight on the weighing machine. Through this article, you will learn about the use and advantages of automatic checkweigher machine and the knowledge of weight distinction. First of all, what are the advantages of automatic weighing machines? 1. 100% sampling; when the automatic checkweigher machine is not used, most companies conduct sampling inspections, especially those with large quantities. Assuming that an assembly line passes 80 products in one minute, the operator randomly selects 20 products per hour, and the sampling rate is about 0.42%; the sample size is too small to reflect the overall situation. 2. Detect whether the product is over or underweight; 3. Ensure compliance with the national average weight law on the weight of packaged products; 4. Perform integrity testing on the entire package without opening the box; 5. The feedback component of the system can change the weight The information is fed back to the filling equipment to adjust the filling volume and effectively reduce waste of resources and short-packed products; 6. Products can be classified by weight; 7. Statistics reflect production efficiency; 8. Save labor and improve production efficiency. Secondly, after understanding the advantages of the automatic weighing machine, let's take a look at how to use the automatic weighing machine correctly. How to use the automatic weighing machine: (1) Maintain good weighing habits when using it. Try to place it in the middle of the electronic checkweigher machine in the process of weighing, so that the platform scale sensor is balanced. Avoid the uneven force of the weighing platform and the fine tilting which may cause inaccurate weighing and affect the service life of the electronic platform scale. (2) Check whether the horizontal drum is in the center before each use to ensure the accuracy of weighing. (3) Frequently clean up the debris on the sensor, so as not to resist the sensor, causing inaccurate weighing and hopping. (4) Always check whether the wiring is loose or broken, and whether the grounding wire is secure. Always check whether the limit gap is reasonable, whether the scale body touches or collides with other objects, etc. Finally, we are looking at how the automatic weighing machine distinguishes weight: the intermediate reference weight (the target weight of the package), the TU1 and TO1 values u200bu200bare the thresholds for separating the weight zones, they are: 1 zone underweight , Qualified weight in zone 2 and overweight in zone 3. This classification method is sufficient for general use, but it cannot accurately describe the production situation. The 3-zone classification method is not suitable for fiscal applications, and there must be two underweight zones in fiscal applications. In this case, a 5-zone classification method is required. The intermediate reference weight (the target weight of the package). The values u200bu200bof TU1, TU2, TO1, and TO2 are the thresholds for separating the weight zones. They are: zone 1 underweight, zone 2 low weight, zone 3 weight qualified, zone 4 high weight , Area 5 is overweight. Adding two partitions can represent the weight distribution more accurately. In the 5-zone classification, TU1u003dTNE, TU2u003d2TNE, there is no provision for TO1 and TO2 values, and they are meaningless from a legal point of view. In practice, the threshold is set to other values, generally smaller than the value given in the specification, in order to conduct financial inspections. TNE, Tolerable negative error, allows negative error. This summary of knowledge about the advantages of automatic weighing machines, how to use automatic weighing machines, and automatic weighing machines for weight distinction hope to be helpful to everyone.
