Automatic multihead weighers have only just begun to be delivered since 1965. Many applications of this type of electronics are regulated by laws and regulations in my country on minimum and average net weights. Operators who sell prepackaged products with a net weight of uniform error values to end users must ensure that the products often needed in the distribution of funds are not used in commodity circulation enterprises. less than some error value. Following this specification is ultimately the responsibility of the manufacturer of such prepackages.
In order to better comply with their own laws and regulations, many countries in the world also require regular maintenance of the measuring equipment (weighing scales) used for this type of production and processing machinery and equipment (called in Europe).“verify”). In addition to the initial market entry and immediate on-the-spot inspection (certification, recalibration), in EU Member States, Russia and Japan, the laws and regulations of such regions also require method certification of such test tools (multihead weighers). The method confirms that most of the measurement accuracy of commonly used instruments and equipment were determined in the previous inspection by the recognition agencies (such as PTB, NMI, etc.) in my country. (EU Member States: MID Control) Announcement to determine whether to deliver according to special production and processing specifications or to readjust the multihead weigher on site is a prerequisite.
MD5 certified. Products that must be weighed can be liquids, powders, or solid ingredients, which can have an infinite number of different net weight values. As everyone knows, some products include a relatively limited number of components, and their independent net weights are widely known.
Therefore, this type of product (in theory) only assumes a relatively limited net weight value. In particular, one or more of the missing parts are likely to be remembered at all times, which contributed to the lack of detail in the final packaged product. The daily task of a driving force inspection scale is to check product consistency and to remove non-detailed product from the production process to ensure sufficient accuracy and precision measurement reliability.
Cohesion practices can be used for individual packaging as well as final packaging, such as cartons. Another daily task of quality management is purely internal quality control, the cause of deviations (too heavy or too light) at the level of the overall overall target net weight indicates an incorrect production process, for example, the actual operation of the net weight of castings, from Its net weight can be seen whether there are disadvantages such as rolling (internal bubbles), and this disadvantage must be eliminated. Categorize.
Classification also applies to the system software, but only as good or bad, some net weight values are accepted or cleared. As everyone knows, another application is to carry out classification in the category distribution. Generally, multiple continuous feeders are used to feed other objects of different super heavy weights into different safety exits or collection containers, and the net weights subsequently included in such safety exits or collection containers are limited to the previously defined net weights category.
For example, collector number 2 includes items of 100g to 120g net weight, while collector number 2 only includes items of 120g to 140g net weight, and so on. Improvement of dosing and dosing process (trend controller) Another daily task is the automatic multihead weigher that actively controls the dosing process. When it comes to the development trend controller of the automatic multihead weigher, its daily task is to fill, cut or laser cut the upper, middle and lower reaches of the automatic multihead weigher according to the relative control signal, so as to achieve the net weight of the target net weight. value and keep it as long as possible.
Therefore, the symmetry again results were relatively evaluated. As a result of the evaluation, a control signal (manipulated variable) is issued to regulate the plus control module. The basic parameters entered establish the authentication method and control characteristics.
This must incorporate the characteristics of the loaded control module for practical operation. Important main parameters“Overall objective”The estimated total overall target net weight to be maintained is specified.
