How to set the set value of the checkweigher
The checkweigher used for weight inspection needs to set the target weight value (Target Weight) and the limit value (Limit) of the weighing product, so as to obtain the weight zone (Weight Zone), so that qualified products, Sorting of non-conforming products. Checkweighers generally used for component inspection are set according to three-component partitions or five-component partitions. The setting of the target weight value: The weight indicated on the product package is the amount paid by the product consumer, which is usually referred to as the 'label weight'. Under normal conditions, except for the tare weight, the target weight value must be set equal to Or slightly higher than the label weight, to ensure that the uniform weight of the same batch of products is not less than the label weight, in order to meet the relevant regulations on product packaging requirements. The quantity of the average weight of a batch of products exceeding the label weight is called 'overfill, Giveway'. 'Overfill' is the part of the product that the manufacturer pays more to the user, and the target weight value exceeds the label weight value. Determine the product's quality. The quantity of 'overfill' should be set prudently. If after the test, the weight data of the product packaging of the feeding equipment is close to the ideal normal distribution, and the feeding amount of the feeding equipment does not change much, it is recommended to confirm by the label weight (plus the tare value of the product) plus 2 times the standard deviation of the checkweigher Target component value. In the actual application process, if the target component value is found to be inappropriate, it can also be adjusted within a small range according to the site conditions. If the control accuracy of the feeding amount of the feeding equipment is high and the feeding amount changes little, then the standard deviation value of the checkweigher is also small, and the difference between the target component value set higher than the label component plus the product tare value is also smaller. The method of setting the limit value: 1. Set according to the allowable shortage 2. Set according to the tolerance value 3. Set according to the on-site operating conditions. The checkweigher used for weight inspection should be checked for the set value before it is put into operation. Setting, which is related to the normal operation of the checkweigher, is also related to reducing the amount of overfill and improving the economic benefits of the enterprise, so it should be paid attention to by the operation and protection personnel of the checkweigher machine.
weigher is an inevitable and critical part of being a manufacturer, and it's more complicated than just manufacturing products and serving customers.
