In the 70 's, the Japanese Agricultural Association to the relevant weighing enterprises raised the issue of green pepper weighing. In Japan, green peppers are usually sold in the form of bagged quantitative packaging.
If the quantitative value of each bag of green pepper is 120g, it is very difficult to install a quasi 120g. As a single green pepper weight heavier, and the difference is large, less related to the interests of consumers, loaded more related to the cost of the enterprise. The traditional way is artificially weighing, that is, in a static electronic weighing, a green pepper to add a green pepper to 115g, and then to find a 5g heavy green pepper added to almost impossible, you must take a small green pepper from 115g, and then add another large one green pepper. If the weight is significantly more than 120g or less than 120g, you need to repeat the above work, so the weighing efficiency is extremely low, and difficult to achieve near the target weight (quantitative value) results. After a lot of investigation and research by technicians, the paper makes use of the combination weighing principle to solve the problem of the green pepper weighing successfully.
