Application of online checkweigher in automated packaging industry

Abstract: Automated packaging uses automated devices to control and manage the packaging process so that it can be carried out automatically in accordance with predetermined procedures. In the whole process of social circulation, packaging can play the functions of protection, beautification, publicity, and sales of products, and improve the competitiveness of products. In the continuous and large-scale industrial production process, packaging

Automated packaging uses automated devices to control and manage the packaging process so that it can be carried out automatically in accordance with pre-defined procedures. In the whole process of social circulation, packaging can play the functions of protection, beautification, publicity, and sales of products, and improve the competitiveness of products. In the continuous and large-scale industrial production process, packaging is the last process.

The realization of packaging automation can effectively improve production capacity, ensure product quality, increase the variety of colors, and is conducive to the sanitation of food and medicine, the anticorrosion and rust prevention of metal products, and the reduction of production costs. Packaging automation can also improve working conditions, especially for the packaging of items that are toxic, irritating, low temperature and humid, and flying and spreading, which are harmful to human health. For those quick, monotonous, frequent, and repetitive operations that easily cause human fatigue, such as boxing, strapping, palletizing, etc., as well as packaging that is difficult to achieve manually, such as aseptic packaging, vacuum packaging, thermoforming packaging, etc., it is more necessary Realize automation. With the development of electronic technology, packaging has developed from a low-level program control based on a single machine with separate electrical appliances to a multi-functional automatic packaging machine and an automatic packaging production line controlled by an electronic computer.

In the manufacturing process, it is inevitable that various errors will occur, such as the overweight or underweight of the product, the large or small quantity, the over-installation of accessories, etc. If such products enter the market, they will bring customers A certain loss will come, and at the same time it will affect the image of the company. Therefore, the product must be tested before packaging. At this time, the automatic checkweigher plays a huge role. The user sets the upper and lower limits of the product weight in the automatic checkweigher system, and the automatic checkweigher weighs the product. Recognize the products outside the set range and automatically remove them. Since the automatic checkweigher is a dynamic weighing on the belt, it can be integrated with the assembly line, so it will not affect the production and packaging speed.

Donggun bestar automation company's automatic checkweigher has three types: high-speed and high-precision, economical and general-purpose, and ultra-large-range type, which can meet the online weighing of various weight products, as large as several hundred kilograms of mechanical parts, as small as one page. All paper can be weighed. Among them, the best resolution accuracy of the high-speed and high-precision automatic checkweigher can reach ±0.05g, which has reached the world's leading level. For example, Vinda Paper Group uses our company's automatic checkweigher to detect the missing quantity of the entire package of paper towels; Wangwang Group uses our company's automatic checkweigher to detect the missing desiccant.

The checkweigher can also be combined with various types of instruments into an all-in-one machine. For example, it can be combined with a cartoning machine to form an automatic checkweighing and cartoning machine; with a labeling machine to form an automatic checkweighing and labeling machine; with a barcode scanner It is composed of an automatic weighing and scanning integrated machine; it can be combined with an inkjet printer to form an automatic weighing and coding integrated machine; in the food and beverage industry, it can also be combined with a metal detector to form an automatic weighing metal detection integrated machine and other combinations. Can be freely combined according to the actual needs of users.
