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
The present invention relates to a kind of method and apparatus that object is carried out sorting by its weight.
Background technology
In the prior art, the method that object carries out sorting by its weight is concluded three kinds:
1, manual weighing separating method, this method are manually to utilize mechanical balance, electronic balance, bar the weighing instrument such as to claim, differentiate the weight for the treatment of sorting objects earlier, and then will treat that sorting objects carries out sorting and grouping according to its weight by hand;
2, the automatic sorting of mechanical balance formula, this method is to utilize lever principle, to treat that sorting objects and standard weights thing compare, scale mechanism can be from trend heavier lopsidedness or upset, thereby will treat sorting objects to both sides sorting come, for example be used for the convertible screening installation of balance of agricultural product and aquatic products sorting;
3, the automatic separating method of weight sensor, this method is: utilize weight sensor will treat that the pressure that weight produced of sorting objects is converted to the signal of telecommunication earlier, machine collection as calculated, processing then, again the data that collect and predefined data as standard are contrasted, come the weight of judgment object with this, computer is controlled executing agency again object is carried out sorting and grouping by its weight then.
Though more than three kinds of method for separating can will treat that sorting objects carries out sorting and grouping according to the difference of weight according to people's requirement to a certain extent, be used for to treat that the sorting objects branch goes into different weight groups or be divided into certified products and defective work, yet for some strict to weight and produce in enormous quantities products, more than three kinds of methods all have weak point.Thereby for example in the capsule in the medicine, tablet, pill or the like being carried out weight sorting rejecting defective work process, more than three kinds of methods just have weak point, because the closely-related specialty goods of medicine conduct and people's health and life security, weight requirement to each medicine all should be very strict, the drug dose deficiency does not reach result of treatment, dosage exceeds standard and then may produce harm to human body, so medicine is carried out strict weight sorting, it is very important that those defective works light partially or that lay particular stress on are sorted out.For the weight sorting of medicine and other sophisticated product, more than three kinds of methods exist following weak point:
One. manual weighing separating method
This method wastes time and energy, and efficient is very low, can't satisfy the sorting work of typical products in mass production at all.
For the production of medicine, it only is applicable to the sampling observation to medicine, can't effectively carry out sorting to each medicine according to weight, thereby substandard product is rejected out.
Two. the automatic sorting of mechanical balance formula
The more manual weighing separating method of this method has had certain progress, makes the efficiency of separation be greatly improved, but the employed mechanical type sorting mechanism of this method has determined this method can't realize the sorting of degree of precision, is particularly taking into account under the prerequisite of the efficiency of separation.So this method is only applicable to agricultural product and aquatic products or the like the less demanding occasion of weight sharpness of separation, and for some for the exigent product of weight sharpness of separation, this method can't satisfy the needs of sorting at all, medicine for example, when the simple grain weight of medicine and the heavy standard of grain differ tens milligrams even a few milligram hour, the automatic method for separating of mechanical balance formula just has been considered to substandard product, so can't satisfy the sorting requirement to delicate objects such as medicines.
Three. the automatic separating method of weight sensor
The most frequently used in this method prior art, more preceding two kinds of method for separating have had very big improvement, it can weigh up the actual weight of each product, thereby realize the sorting of degree of precision, the efficiency of separation also has further raising, yet the fatal shortcoming of this method is a system complex, cost an arm and a leg, operation inconvenience, the maintenance cost height is unfavorable for promoting.
In pharmaceutical industry, along with the continuous improvement of pharmaceutical production equipment, its production efficiency improves constantly, the speed of production of tablet and capsule can up to 2,500,000/per hour.A weight sensor of the automatic separating method of weight sensor once can only detect a granule product, so the detection efficiency of single weight sensor still is limited, though this method can improve the efficiency of separation of complete machine by the quantity of continuous expansion weight sensor, but owing to be subjected to the influence of factors such as equipment volume, the efficiency of separation of its complete machine still is difficult to satisfy the requirement of pharmaceutical production, also be that a very important reason is exactly simultaneously: for for global pharmacy corporation, they do not wish to know with high cost the actual weight of each medicine, they are desired just can a kind of fairly simple low cost equipment, after product is by detection, checkout equipment can stay by the product that weight is qualified, and underproof rejecting is come out.
Summary of the invention
The purpose of this invention is to provide a kind of sorting objects for the treatment of and carry out the method and apparatus of sorting and grouping according to its weight, if be applied in the pharmaceutical production field, the heavy underproof medicine of the grain that then can reject in the production process fast to be occurred.
