What is computer combination scale?
Computer combination scale also called
combination scale
option combination weighing apparatus, which is
composed of a plurality of separate inlet and discharging structure weighing unit, computer use of permutation and combination principle of weighing unit load to
automatic optimization combinatorial computation, obtains the best, closest to the target weight value weight combination package.

The last century 70's,
professional hair scissor
the Japanese Agricultural Association to the weighing
enterprises put forward green pepper weighing topic. In Japan, green peppers are often packed in bags packaging in the form of supermarket sales, if each bag of green
pepper quantitative values are 120 grams,120 grams to quasi is a very difficult thing. Because a single green pepper with heavy weight, and the difference is bigger,
with little relation to the interests of consumers, with much related to the enterprise cost. The traditional way is weighing artificial, i.e. in a static electronic
scale weighing, a green pepper pepper with a cumulative 115grams, then find a 5 gram peppers added is almost impossible, it must be from115 grams
professional thinning shears
to a small green pepper, add another a large green pepper. If the weight
exceeds120 grams or less than 120 grams of words, but also need to repeat the above work, this weighing efficiency is very low, and it is difficult to achieve close to
the target weight ( quantitative values of the results ). Technical staff to undertake a large number of investigation and study, using the combinatorial weighing
principle successfully solves the problem of green pepper weighing.

The working principle of combined scale
1products in the transverse pipe, through the main feeder vibration, so that materials in the conical funnel on the product evenly distributed to the linear feeder
plate.

products to enter the weighing bucket, when
following a weighing bucket no product or when weighing bucket products do not make, product will automatically flow into the weighing hopper.
5products in the weighing hopper, the sensor generates a weight signal, then through the lead wire is transmitted to the control device on the motherboard, motherboard
CPU read and record each weighing hopper weight, through calculation, analysis, combination, choose the most close to the target weight of combination weighing bucket,
when allowed to

discharge signal, CPU issued a command to start drive
opens the selected weighing bucket product is discharged to the finishing groove into the collecting bucket, if not directly into the collecting bucket machine packing
machine.
6 in the CPU received a discharge signal allows the packaging had issued orders to open the boot drive collection hopper discharge of product to the packaging machine,
packaging and to stimulate the
hose couplers
packaging signal, also from the weighing bucket again
released products down ( combination of scale and the vertical packaging machine or to the bag packaging machine connection ).
The main characteristics of computer combination weigher
1 weighing speed
2 dynamic accuracy is very high
3a high degree of automation
The application scope of computer combination weigher
Application on potato chips, rice crust, puffed food, walnuts, pistachios and so nuts, candy, melon seeds, jellies, Tangyuan, dumplings frozen, lover plum, peanut,
almond and other snack foods such as various granular, flaky,
push-lock fittings
strip, spherical,
irregular shape need quantitative weighing manufacturer.x123
