Computer combination said eight head weigher, ten head weigher, 12 head weigher, 14 head scale, 16 head weigher, 24 in scale or more, of which every head is a single scale, separate weighing.
Material from the above vibration cutting groove through the main vibration plate down, material to reach the head of the line of vibration plate.
When the first layer of hopper (
Known as the storage hopper)
Is empty, according to set good vibration time, the material from the vibrating wire plate vibration to the hopper.
When storage hopper weighing hopper below is empty, after feeding hopper opening, put the thought weighing hopper, weighing hopper weighing.
Suppose we target weight of 250 g, we take 5 bucket combination (
Take five heads up as a result)
A total of 10 head, take 5 bucket method in 10 head has 252 kinds.
Because we want to take 5 bucket, so in setting the vibration of the vibrating wire plate time with target weight of 50 g as per bushel, vibration on the material will be near 50 g, because the material size, also how many, is not very uniform, so there will be how much the weight of per bushel, but will be in the vicinity of 50 g, both there will be a bucket of lay particular stress on, also can appear lighter, it doesn't matter big deviation even if some of the weight of the bucket, because there are 252 kinds of method, the probability of 5 bucket weight up to 250 g is very large,
Of course there will be a plus or minus 0.
1 -
The error of the 2 g)
。
Traditional quantitative
automatic packing scale is charging and weighing, continuous feeding, before reaching the target weight data when vary a little with the target weight must append a known objects, namely the crude measurement before finishing, such as called larger or heavier when there is a bigger error, this is affecting the weighing accuracy.
And is composed of multiple independent computer combination said feed discharging structure weighing units, general computer combination said consists of 8 ~ 32 weighing unit.
Computer by using the theory of permutation and combination to the weighing unit automatic optimum combination of the amount of load, it is concluded that, close to the combination of quantitative values for packaging.
Such as jia wei a 10 head computer combination known as example, each weighing unit for weighing, each weighing hopper and will be a heavy weight data into the computer, the computer optimization combination, according to according to the principle of combination of mathematics and computer technology, ten weighing unit can achieve 1023 kinds of combinations, computer is chosen from among the 1023 kinds of combination is close to the combination of the objective weight values.
So the artificial repeatedly collocation, and it is difficult to accomplish the work of quantitative values.
Computer combination is set according to the weight of the automatic weighing, and automatically select close to the target weight combination.
Mainly used for weighing computer combination said puffed food such as potato chips, crispy rice, biscuit;
Large shell nuts such as walnuts, hazelnuts, pistachios;
Frozen food such as dumplings, dumplings;
Jelly, melon seeds, lover mei, peanuts, nuts, chocolate and other snack foods;
Potatoes, carrots, apples and other crops;
Health care tea, Chinese medicine, such as the pill medicine products;
Washing powder, feed, plastic, metal parts, etc. ;
Quantitative weighing of shellfish aquatic products.
Object: the quantitative weighing and packing need at home and abroad various granular, sheet, strip, irregular shape of the food, feed, plastics, pharmaceuticals, jin of parts and chemical products such as computer combination said production or packaging manufacturers.
