Combination application of automatic checkweigher

by:Kenwei      2020-05-31
Automatic checkweigher is a special equipment used by food and pharmaceutical companies to check the weight of products online. This testing equipment not only ensures the accuracy of the product weight, reduces the production waste caused by the weight exceeding the standard value, but also improves the trust of the product in the minds of customers. With the increase in the number and role of automatic checkweighers in the production process of enterprises, the equipment has gradually shifted from pure weight detection to integrated system weight detection. These integrated systems are: Combination of automatic checkweigher and metal detector This combination is one of the most commonly used combinations in food companies. In this system, the metal detector is directly installed on the conveyor at the front of the checkweigher and shares an automatic rejecter with the checkweigher, which saves investment in equipment costs. At the same time, the control system is controlled by the screen of the checkweigher to control the metal detection machine, so that the weight detection and metal detection are completed under the same control screen, which effectively reduces repeated operations and improves work efficiency. This combination is particularly popular with instant noodle manufacturers. Combination of automatic checkweigher, printer and labeling machine The combination of checkweigher and coding is particularly suitable for meat product manufacturing enterprises, and the combination of checkweigher and labeling machine is suitable for the production of quick-frozen food for sliced ??meat products. Because the weight of meat products after cutting is not unique, a printer or labeling machine is combined at the back end of the checkweigher to directly print the weight of the product on the product packaging or the printed label, which can effectively reduce duplication Operation, saving packaging costs for enterprises. Combination of automatic checkweigher and packaging machine The combination is based on the feedback control system of the checkweigher, and thus achieves the purpose of directly controlling the front-end packaging machine by the checkweigher. The advantage of this type of combination is that the accuracy of the feeding of the packaging machine can be continuously adjusted online, which effectively avoids the loss caused by the previous adjustment of the filling amount of the packaging machine that must be stopped to complete. Combination of automatic checkweigher and barcode reader This combination is one of the best solutions when user companies continue to add production lines and are reluctant to purchase new automatic checkweighers. This combination is based on the random weighing system of the checkweigher, which can detect different products on an automatic checkweigher. Suppose you have three production lines, and the standard weights of the products on each production line are 200g, 500g, and 700g, respectively, and the upper and lower limits of the weight are set to ± 20g. The order in which the three production lines pass the checkweigher is 200g, 500g, 700g, 700g, 500g, 200g, or a variety of random orders. At this time, the automatic checkweigher can automatically adjust the standard weight and the upper and lower limits, and make a correct judgment. However, this system has its unavoidable limitations, when the product weight difference is not very large (for example: the standard weight of the product is 200g, the standard weight of another product is 180g, and the upper and lower limits of the product weight are set to ± 20g), The automatic checkweigher cannot make a correct judgment. In this case, the automatic checkweigher needs to be additionally equipped with a bar code reader. The bar code reader provides information such as the standard weight of the product and the upper and lower limits of the product weight, so that the automatic checkweigher can make a judgment. At present, this type of combination has broken through the field of food production and has been widely used in other production fields.
