Long microcomputer combination according to the packing of the performance of the two aspects of accuracy and speed than traditional measurement methods have greatly improved.
At present, the industry generally long microcomputer weighing error of combination said would be a slant is 0.
5 -
1.
0 g (
Scope of weighing 500 g)
。
At the same time, because of the long microcomputer combined said operations by using the computer, so improve the speed combination (
The weighing speed)
, ten head of a bull microcomputer, according to the combination weighing speed can reach 70 times/min, 14 head long microcomputer, according to the combination weighing speed can reach 120 times/min.
Fujian Dali food factory is a large-scale enterprise specializing in the production of potato chips, 2004 years ago has been the traditional measurement methods (
A single cup measurement)
, its speed can reach 25 times/min, single bag weighed average error value is greater than 4 g, namely each bag of potato chips (
40 g)
Is not allowed for weighing and packing at least 4 g potato chips.
Output of 4000 tons per year calculation, the enterprise only for a lost each year nearly 400 tonnes of potato chips, in order to solve the problem of product measurement is allowed to, companies attempted to buy the combination of more than a microcomputer said (

。
Said, using a combination of long computer companies will actually weighing error a value of 1 g per bag of potato chips,
40s)
Weighing error of losses than didn't say when using a combination of long microcomputer reduced more than 3 grams, through cost accounting confirmed that bulls microcomputer combination according to use less than half a year to recover all the investment.
Now fujian Dali group, including the national nearly 10 branch factory, using a combination of more than 40 sets of domestic microcomputer said.
Multi-head computer combination according to quantitative weighing section is the key to food factory automation production equipment, before our country are rely on Japan, Australia and other countries import, because the price is expensive, hindered the wide application of computer multi-head computer combination said with popularity.
Zhongshan refined
packaging machinery co. , LTD long microcomputer combination said, and said in multi-head computer combination technology of grade, let originally regarded as 'noble products' computer multi-head computer combination is no longer the patent of big enterprises, more the pursuit of high speed, high efficiency of domestic enterprises, are eliminated in the past, let a cup of type or the artificial charge fees, such as the quantitative weighing packaging production line, with high-tech, higher automatic degree multi-head computer combination according to quantitative weighing and packing system.
Domestic food companies want to learn more about the bulls microcomputer, according to the combination must introduce multi-head computer combination of choose and buy according to three factors that should be paid attention to.
Multi-head computer combination of choose and buy says the first thing to consider is long microcomputer combination weighing whether to match the line speed.
Generally long computer combination according to quantitative weighing and packing system is mainly composed of long microcomputer combined said, vertical
packaging machine, vibrating feeder, Z conveyor, support platform, etc.
Multi-head computer combination according to the weighing speed mainly depend on the number of participating in weighing hopper.
The more weighing hopper, weighing speed is faster, if users have a ready-made packaging machine, then selecting the bulls the speed of microcomputer combination according to refer to the
packing machine running speed, but long microcomputer combination according to speed should be slightly higher than the speed of the packaging machine.
Secondary product weighing range, size, shape, material, presence of viscosity and other characteristics, such as weighing scope, material is larger, should consider to choose the 14 more Numbers of computer long combination said;
If any viscous material, the contact with the material into the hopper, weighing hopper should have prevent stickiness, will generally choose concave-convex version of the scale, otherwise it will affect the bulls microcomputer combination according to the speed and precision.
The third factor is long microcomputer combination according to the weighing accuracy.
While the bulls microcomputer combination said has been very mature products, but these are not the same load sensors used in the measurement accuracy.
Some bulls microcomputer said portfolio are analog signals, using analog signal is basically piracy scale at present, the scale is mainly performance is not stable, easy to burn the mainboard, IC patch second-hand sources, the biggest problem is the product out of the problem basically do not have ability to improve.
Some are digital weighing, fine, the main production type waterproof long computer combination, according to all adopt the digital high precision weighing signal, is the perfect combination of precision and speed.
Long in the process of using basic microcomputer combination does not need maintenance, only for daily cleaning.
In addition, the food industry in the process of using a combination of long microcomputer said pay special attention to two points: first, as far as possible to keep the continuity, stability, and the rationality of the feed, if the material is more and less, in the weighing hopper material too little or too much, can cause long microcomputer combined said combination difficult or combination, which lower the speed and accuracy in the weighing;
Second, the mounting weighing hopper should be as light as possible, when too much force will make load sensor is damaged and can't even use weighing precision.
Third, use every day, after dealing with the main vibration plate, vibrating wire plate, into the hopper, weighing bucket and measured only by direct contact with the place clean, every time before use to check whether there is foreign body on the hook the weighing hopper, and after use to remove the weighing bucket the dust off the hook.
There is a strong need for more research on , in order to be able to provide strong and conclusive evidence of their checkweigher effects. However, recent studies have provided valuable insights into how the intake of may result in improved
multihead weigher.
