Traditional quantitative automatic packing
scale generally go through rough measuring, measuring the weighing process, especially the fine measurement process need to add little by little, takes longer, weighing speed.
For example 1 kg quantitative automatic packing scale under the weighing speed, generally in the 20 ~ 30 packages/minutes, the computer according to the linear combination
of combination optimization operation of 14 unit weighing scales generally can reach 100 ~ 120 bags/min, than quantitative automatic packing scale weighing 4 ~ 6 times as fast, and easy to match the various kinds of packing machine
Greatly improve the efficiency of the packaging, more suitable for modern production management requirements.
Material in the weighing hopper, weight by sensor signals, then send the motherboard to control devices through lead, the motherboard CPU to read and record each weighing the weight of the bucket, then through calculation, analysis, combination, close to the target weight of combination weighing hopper, when accepting the request sent to the packaging machine
feeding signal, the CPU sends a signal to start the weighing bucket motor drive to open the selected in the chute under the weighing bucket unloaded the products enter into the packaging machine (
If there is one set of hopper, weighing hopper good combination directly after put expect aggregate bin, when requested for feeding signal launch set to the packaging machine feeding hopper motor)
When weighing hopper (
Linear combination after put the material in, say to the packaging machine signal has a feeding, packing after receive to have feeding signal to start sealing and cutting bag, when good packaging mechanism a bag and then send the request to the linear combination according to the feeding signal called linear combination of blanking, so cycle.
Linear combination accuracy under the condition of the same, according to the weighing range of automatic quantitative packaging scale larger, usually quantitative automatic packing scale in the same accuracy of weighing range control within the four times, in small scale quantity according to the linear combination of weighing range can be up to ten times.
Combination according to manufacturer to see from a large number of test results can be both weighing scale difference exist.
Such as in 10 grams to 1 kg of weighing range, linear combination according to X (
Levels of accuracy requirements, especially in small weighing segment is rare.
To the accuracy level unchanged, only narrow scope of weighing automatic quantitative packaging weighers, formation period of weighing, relying on more than one series of products, production can realize the request of manufacturers one.
Generally, manufacturers are almost not accept this kind of phenomenon.
This creates the limitations for its practical application, different packaging specifications reach certain production areas (
But the demands about the use of precision. Smart Weigh
can also foster research that is more useful and influential in society at large.
