1.1 BASIC INTRODUCTION
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.
This machine’s model is JW-A□□□-□□, which is explained as follows:
JW - A □ □ □ - □ □ Combination weigher: layer of hopper, 1 is single layer,
default as double layer. Linear weigher: layer of linear VB, 1 is single layer,
default as double layer. Product generation: default as the first generation, B stands for the second generation, etc. Heads Qty Default as standard plain hopper, H means standard Dimple hopper. M means larger plain hopper, HM means larger dimple hopper. Model: Default as multihead weigher, X means linear scale. “A”-filling & weighing Machine, “B”-weighing& packaging system, “C”-Packaging machine; “D”-Conveying machine, “E”-Finished products checking device.

3. WORKING THEORY
3.1 FEEDING
Chart 3-1-1
5
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. As shown in Chart 3-1-1.
3.2 PRODUCT DISTRIBUTION AND WEIGHING
Chart 3-2-1
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. As shown in Chart 3-2-1.
3.3 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.
1. The parameters related with “weight in weigh hopper”: ‘AFC’, ‘MAIN AMP’, ‘LIN AMP’, ‘AV COMB
HPS’, ‘SGL HP WGT’.(Refer to 6.2 Parameter-Setup for details)
AFC0：The bigger ‘Main AMP’ (Main VB Amplitude) and ‘Lin AMP’ (Linear VB Amplitude) are,
the heavier weigh hoppers are.
AFC1：The bigger ‘AV COMB HPS’ is, the lighter Single Hopper Weight is.
AFC2：The bigger ‘SGL HP WT’ is, the heavier each hopper weitght is.
2. The parameters related with combination: ‘OPTIMUM’, ‘Combined Hoppers’
OPTIMUM： the bigger this value is, the higher the accuracy is. As shown in chart 3-3-2, if
the ’OPTIMUM’ is 98, then the best combination ‘6’ will be selected and there is no need finding other 6
combinations.
Combined hoppers：The bigger this value is, the higher the pass rate is. As shown in Chart 3-3-2, if
there is no qualified combination weight, and if the actual combined hoppers number ≥ ‘Preset
Combined HOPPERS’, then it will be forced to discharge in order to increase the whole running
continuity. If the actual combined hoppers number ≤ ‘Preset Combined HOPPERS’, then it will wait
for the discharged hoppers to make combination again.
Chart 3-3-1
Chart 3-3-2
3.4 DISCHARGE
There are four ways to discharge weighed products to next equipment:
1. Direct Discharge (Timing Hopper Model 0): Product is directly discharged from the discharge chute
gate.
7
2. Discharge by Timing Hopper (Timing Hopper Model 1): 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. As shown in Chart 3-4-1
Chart 3-4-1
3. Timing Hopper Distribution (Timing Hopper Model 2): 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 is to make full use of the high speed of combination weigher. As
shown in Chart 3-4-2
Chart 3-4-2
8
4. One timing hopper + AUTOMATIC CHECKER (Timing Hopper Model 3): Product is firstly stored in
timing hopper after dropping from Weigh Hopper; the timing hopper shortens the drop time of the products.
When there are unqualified products, the automatic checker will be on and discharges the reject to the
retriever to prevent it from entering the next procedure. As shown in Chart 3-4-3

5.3 ZERO OPERATION 1. After turning on the machine, an attention of “PLS Press Zero” will be displayed on the homepage,
which reminds you that you have not made manual Zero Operation. As shown in chart 5-3-1. (Because
when you turn on the machine, the auto zeroing control has made a zeroing to the hoppers which are
actually not emptied yet in last operation, which will result in inaccurate zeroing.)
Chart 5-3-1
After this operation, as shown in chart 5-3-2, it will display “Be in zeroing, pls wait.”
Chart 5-3-2 18
2. Press Zero on the homepage with opening all weigh hoppers and emptying the rest products in the weigh
hoppers. And each load cell will have a zeroing by turns in five seconds.

display the current date on the screen. As shown in chart 5-3-3.
Chart 5-3-3
Failure-analyses during the zeroing operation:
●‘Tick’ one time means the zeroing operation is OK.
●‘Tick’ two times means that there is a load cell with 0.5-20g float after zeroing operation;
●‘Tick’ three times means that there is something wrong with a load cell with above 20g float, and it will
display E on the screen and stop the hopper during the running.
5.4 EMPTY

11. Main AMP/Main Vibrator Amplitude: it refers to the strength of the main vibrator amplitude. Press
number key to input value from 01 to 99. The bigger the value is, the stronger the main amplitude is.
Recommendation: 40-90.
12. LIN AMP/Linear Vibrator Amplitude: it refers to the strength of the linear vibrator amplitude. Press

34
Recommendation: 50-80.
18. Over Sgl Tm/Overweight signal time: it means the lasting time for the combination weigher to send
‘overweight signal’ to next equipment, when it dumps the overweight materials. Input 01-999, unit is 10ms.
19. Dump Sgl Dly/Dumping signal delay: under the circumstance of ready combinations, the combination
weigher will discharge materials to the packaging machine at once, after receiving the ‘dump asking signal’
from packaging machine. And then combination weigher delays a period of time to send a 100ms
‘confirmed signal’ to the packaging machine. Input 01-999, unit is 10ms. Recommendation: 50-80.
20. Stgger Dump Tm: When there is a limit for Max Dump Hoppers, that’s to say, one combination will be
divided into several dumpings with a certain interval to discharge. Unit is 10ms.
21. Stable TM/Sample stable Time: in order to ensure weighing precision, after opening the feed hopper, it
will wait a moment to stabilize the sample products in the weighing hopper and then begin to read the load
cell data. Input 01-999, unit is 10ms. Recommendation: 70-100.
22. Multicomb TMS/Multi-combination Times: one target weight will be divided into many combinations.
In this case, Weight of one combination = Target Weight / Multicomb Times. This function is used to weigh
products with big target weight.
23. Max Dump HPS/Max dumping hoppers: In order to reduce the blockage of puffy products, one
combination will be divided into many times to dump. Max Dump Hps refers to the max simultaneous
dumping hoppers in a combination dumping. Input 1-9, 0 means this function is closed.
Related Parameter: Stagger Dump Time
24. Min HP WT%/Minimum single hopper weight%: it means that the single hopper weight is less than the
single combination weight percent, which is regarded as ‘low product’, and not allowed to attend the
combination, and it needs feeding material. Input 1-99, unit is %. Recommendation: 11%--15%.
25. IDLE/No combination times: It refers to the times for one single hopper not attends in combinations, which is
applicable to limit the products remaining times in the weight hopper. For example, we set IDLE as N, if one weigh hopper
