Fully automatic multihead weighers have been in service since around 1966. Many uses of such scales are subject to Chinese laws regarding minimum and average net weights. Manufacturers who sell prepackaged commodities with a uniform net weight tolerance to the end-user market must ensure that the commodities invested in the circulation of commodities are not less than a certain tolerance value.
Following this standard is ultimately the obligation of the manufacturer of such prepackages. In order to better comply with pre-packaging policies and regulations, many countries around the world also require regular maintenance of the measuring equipment used in this production and manufacturing equipment (automatic multihead weigher) (called in Europe).“Certification”). In the EU countries, Ukraine and Japan, the laws and regulations of this region, in addition to the early sales and marketing promotion and timely on-site inspection (verification and recalibration), also stipulate that this kind of multihead weigher carries out formal verification, confirming that our country Identity organizations (such as PTB, NMI, etc.).
) in the past experiments basically confirmed the measurement accuracy of commonly used instruments. (EU countries: MID policies and regulations). Formal verification is a prerequisite for delivery under specific manufacturing standards or recalibration of the fully automatic multihead weigher on the spot.
md5 verification. Items to be weighed can be liquid, powdered, or solid components that can have an infinite number of different net weight values. However, some products include a relatively limited total number of parts whose individual net weights are known to some extent.
Thus, only a limited number of net weight values are assumed to be compared (in theory) for this commodity. In particular, there is a good chance that only one or more of the missing parts will be remembered, which will make the final package less detailed. The daily task of the dynamic fully automatic multihead weigher is to check the consistency of commodities and to remove non-detailed commodities from the processing process with sufficient accuracy of measurement confidence.
Consistency manipulation can be used not only for individual packaging, but also for the final packaging of the production line, such as cartons. Quality Management. Another daily task is purely internal quality management, in which errors in the overall target net weight (too heavy or too light) indicate incorrect manufacturing, such as the manipulation of the net weight of a casting, from which the net weight can tell if there is any shrinkage ( internal air bubbles), which dictates that the controlled part be removed.
Categorize. In the applications mentioned above, categorization is also applied, but only for good or bad, some weights are accepted or rejected. As everyone knows, another application is the classification in the actual sense of type assignment.
Generally, several continuous feeders are used to feed commodities of different net weight levels into different safe passages or collection vessels, and then such safe passages or collection vessels only include commodities whose net weight is within the previously defined net weight category. For example, collection container 2 includes items with a net weight between 100 grams and 120 grams, collection container 2 only includes items with a net weight between 120 grams and 140 grams, and so on. Lifting of the canning and seasoning process (Trend Control Board) Another daily task of the fully automatic multihead weigher is to actively manipulate the canning process.
To put it bluntly, the daily task of the development trend control panel of the fully automatic multihead weigher is to harm the upstream and downstream canning, laser cutting or slicing of the fully automatic multihead weigher according to the relative manipulation data signal, so as to achieve the net weight value defined as the overall target net weight. , and keep it as stable as possible. Thus, the weighing results will be rated relatively. As a result of the evaluation, the manipulation data signal (manipulation variable) is pushed to adjust the refill module.
Enter the main parameters to determine the type of rating and control characteristics. This must be incorporated into the characteristics of the canning equipment to be operated. The main parameters“Target”Defines the overall target net weight that must be maintained.
