M Series Multi Head Weigher
M10/14
M Series Multi Head Weigher (MS10/M10/ML10/MS14/M14/ML14) uses factorial combination theory, selecting the closest combination to the target weight for high accuracy weighing of granular products.
Features
- This machine adopts factorial theory, chooses one combination which is closest to the target weight from plenty of qualified combinations.
- This machine is particularly applicable for weighing granular products in pipelining operation.

Working Principle
Feeding
Product is firstly delivered by Conveyor into upper storage funnel, then discharged and distributed to linear vibrator pans with the help of the top cone. Product thickness can be adjusted by adjusting the height of storage funnel post.
Product Distribution and Weighing
Product is distributed evenly from Top Cone into each Linear Feeder Pan and stored in Feed Hopper. When Weigh Hopper finishes the previous weighing and discharges the combination, the products in Feed Hopper will be dropped to Weigh Hopper to be weighed and combined.
Combination
The machine CPU will process the weight data received from each Weigh hopper, and calculate out numerous qualified combinations which comply with the target weight, then choose the best one to discharge.
The parameters related with "weight in weigh hopper": AFC, Main AMP, Line AMP, Average Combine Hoppers, Average Hopper Weight%.
- AFC Disable: The bigger Main AMP (Main VB Amplitude) and Line AMP (Linear VB Amplitude) are, the heavier weigh hoppers are.
- AFCT: The bigger Average Combine Hoppers is, the lighter Single Hopper Weight is.
- AFCW: The bigger Average Hopper Weight% is, the heavier each hopper weight is.
The parameters related with combination: OPTIMUM, Combined Hoppers.
- OPTIMUM: The bigger this value is, the higher the accuracy is.
- Combined Hoppers: The bigger this value is, the higher the pass rate is.
Discharge
There are four ways to discharge weighed products:
No Timing Hopper
Product is directly discharged from the discharge chute gate.
Discharge by Timing Hopper (one bag)
Product is firstly stored in timing hopper after dropping from weigh hopper, and then dumped to next equipment. This function is to collect products and shorten the drop time.
Timing Hopper Distribution (two bags)
Product is firstly stored in timing hopper after dropping from the weigh hopper, and then dumped to next two packaging machines according to the dumping asking signals. This function makes full use of the high speed of combination weigher.
One Timing Hopper + Automatic Checker (rejection)
Product is firstly stored in timing hopper after dropping from Weigh Hopper; the timing hopper shortens the drop time. When there are unqualified products, the automatic checker will be on and discharges the reject to the retriever.
Safety
- No bumping or strong pressures on weigh hoppers.
- Check and empty the rest product inside the machine before running.
- Press Zero to empty hoppers before the first running.
- Turn off the power before repairing and cleaning the machine.
- When electronic part fails, non-electronic-engineer is prohibited to repair the machine.
- Be careful and cautious when cleaning and repairing the machine, because there is certain distance between the weigher and the ground if the weigher is installed on the top of the packaging machine.
- Direct current for the connection signals with other equipments (packing machine, conveyor, etc.), should be no more than 30V, the overloading current should be no more than 100mA.
- It is prohibited to touch the hopper while the machine is running.
Working Environment
Food packaging should be operated under aseptic and non-dust environment.
