Method and apparatus for sorting electrostatic attraction type weight

Abstract

The invention relates to an electrostatic attracted weight sorting method and equipment, which can electrify the to-be-sorted objects with a charge, the sorting mechanism with another charge. The attracting force between the to-be-sorted objects and the sorting mechanism can reach an expected value through regulating the distance between the to-be-sorted objects and the sorting mechanism. Therefore the to-be-sorted objects with a weight smaller than the sorting standard are attracted by the sorting mechanism; the to-be-sorted objects with a weight larger than the sorting standard can not be attracted by the sorting mechanism, while the to-be-sorted objects with a weight equal to the sorting standard maintain the original state. The to-be-sorted objects being attracted and the to-be-sorted objects not being attracted are collected respectively, thus the sorting process is completed. Compared with the existing weight sorting method, the method has the advantages of high efficiency and sorting precision, convenient in popularization, and is particularly suitable for the weight sorting of solid preparations such as capsules, tablets and pills during the production process of medicine so as to remove non-conforming products and enhance the overall quality of medicines.

Description

technical field [0001] The invention relates to a method and equipment for sorting objects according to their weight. Background technique [0002] In the prior art, there are three methods for sorting objects according to their weight: [0003] 1. Manual weighing and sorting method. This method is to manually use weighing tools such as mechanical balances, electronic balances, and rod scales to first determine the weight of the objects to be sorted, and then manually sort the objects to be sorted according to their weight. classification; [0004] 2. Mechanical balance type automatic sorting. This method uses the principle of leverage to compare the objects to be sorted with the standard weight objects. The balance mechanism will automatically tilt or flip to the heavier side, so that the objects to be sorted will be moved to the two sides. Side sorting, such as balance tilting sorting equipment for sorting agricultural and aquatic product...

Problems solved by technology

A weight sensor in the weight sensor automatic sorting method can only detect one product at a time, so the detection efficiency of a single weight sensor is still limited, although this method can improve the sorting efficiency of the whole machine by continuously expanding the number of weight sensors. However, due to the influence of equipment volume and other factors, the sorting efficiency of the whole machine is still difficult to meet the requirements of pharmaceutical production. At the same time, it is also a very important reason: for pharmaceutical companies around the world, they do not want to use High price. Knowing the actual weight of each pill, what they expect is to have a relatively simple and cheap equipment. When the product passes the inspection, the inspection equipment can keep the qualified product and reject the unqualified one.
