How to choose a suitable checkweigher (online checkweigher)

2024-06-19

checkweighers are mainly used on automated production lines that require automatic weighing to automatically detect the weight of products or to grade and sort them by weight. They are mainly used in the pharmaceutical, food, toy, hardware, chemical and other industries to replace manual weighing, improve production efficiency and reduce labor costs. There are many types and brands of checkweighers on the market. How to choose a suitable checkweigher (Online Checkweigher)?

To select a suitable checkweigher for products that need to be checked, the weight, size, shape, running speed, measurement accuracy, rejection method, waterproofness, explosion-proofness, etc. of the product are all factors that need to be considered. Let's take a specific case to illustrate.

For example, the checkweighing demand of a pharmaceutical factory for liquid bottled medicine is as an example. The shape of the filling bottle is cylindrical, the height is 80mm, the diameter is 35mm, the filling speed is 120 bottles/minute, and the qualified weight range is 19.5-20.5g. Each bottle needs to be weighed, and those that are too light or overweight need to be rejected. In order to ensure that all products leaving the factory meet the standards and the number of products that are rejected by mistake due to weighing errors is not too large, the accuracy of the checkweigher must reach at least 0.05g. For this checkweighing requirement, if an ordinary belt checkweigher is used, the weighing accuracy of the existing technology can only reach 0.1g at most, and the bottles are easy to tip over when moving between the belts.

This checkweigher developed by Changzhou Excellence Automation System Co., Ltd. is specially used for high-speed and high-precision checkweighing of cylindrical objects such as bottles and cans on automated production lines such as pharmaceuticals, daily chemicals and food.
