THEMA:

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.

Computer combination weigher source

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.

2when the crosscutting bucket product not or was not the level photoelectric detector to measure, as the motherboard to signal, then through the board to a signal feed

conveyor feeding.

3linear feeder vibration, the amplitude and the vibration machine time of the product to each inlet hopper.

The 4driving device, stepping motor, open feed sharpener 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 pneumatic fittings 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
