Combination Weigher Weighing Principle and Workflow
Discover how a combination weigher, also known as a multihead weigher, boosts efficiency and accuracy in food and packaging industries. With advanced weighing principles and smart workflow, Kenwei delivers reliable, high-speed solutions that cut costs, ensure quality, and maximize production.
A combination weigher, also known as a multihead weigher, is a high-precision automatic weighing device that applies advanced technology and intelligent algorithms. It is widely used in industries with strict measurement requirements, including food, pharmaceuticals, and daily chemicals.
By ensuring accurate measurement, automation, and intelligent management, combination weighers enhance production efficiency and product quality. They can automate the entire packaging process—from feeding, metering, and filling to date printing—greatly reducing manual labor and operational costs.
What Is the Weighing Principle of a Combination Weigher?
The core weighing principle of a combination weigher is based on simultaneous weighing using multiple independent weighing units, typically ranging from 8 to 32.
-
Each weighing hopper records the material weight.
-
The built-in control system compares data with the target weight.
-
An optimization algorithm selects the best combination closest to the preset value.
This method ensures packaging accuracy, reduces overweight or underweight errors, saves raw materials, and improves batch acceptance rates.
How Does a Combination Weigher Work?
1. Feeding
Products are transferred to the infeed funnel by conveyor and evenly distributed into linear vibrator pans by the vibration of the top cone.
2. Distribution
From the linear vibrator pans, products drop into feed hoppers. After the weighing hopper completes the previous cycle, the feed hopper opens to release product into the weighing hopper.
3. Combination
The CPU receives data from each weighing hopper and calculates the most accurate combination according to the target weight.
4. Discharging Methods
There are four ways to discharge products into the next equipment:
-
Direct Discharge (Timing Hopper = 0): Products are discharged directly from the collecting funnel.
-
Timing Hopper Discharge (Timing Hopper = 1): Products are stored in a timing hopper, then discharged to reduce drop time.
-
-
Dual Equipment Discharge (Timing Hopper = 2): Products are stored in a timing hopper, then discharged into two machines separately, maximizing high-speed output.
-
-
Timing Hopper + Auto-Sorting (Timing Hopper = 3): Products are stored in the timing hopper, and unqualified weights are automatically sorted into a reject channel.
