Nails Packing Machine /Fasteners Multiweighing Machine

WE-388A Nails Packing Machine ,Fasteners Multiweighing Machine


1 Compatibility :Normal hardware parts like screw, bolt nut washer dowel plug , need to be packed with same machine.(almost all small parts is able to pack with same machine except some parts which is able to hung each other so effect the accuracy and the parts which is too heavy or big as it may stuck in the weigher. )

2 Quantity : You can adjust quantity or weight according to your requirement , like 20 50 100 500pcs / bag .the range is about 20~5000g .

3 Accuracy :1%2%, normally it’s about 1~3 pcs more per bag.

4 Capacity :10~30 bag/min according to the weight per bag.

5 Operation : Feeding the hardware parts into the loading hopper , set in the quantity or weight per bag on the touch screen , press start button then machine will fully automatic feeding the parts into multihead weigher for weighing , then filling into bag former which the machine parts make the bag , seal and cut the bag . conveyor send one finished bag to your table or box.

6 Change parts: When you need the machine to pack another parts , you can choose the exactly saved option in the interface screen then machine will adjust themself like the multihead weigher vibrating frequency , the speed . As it will be different according to different kinds of parts which the shape size weight is different so ensure the high accuracy and speed. Machine is able to save about 99 kinds of different option , we can add more according to your requirement.      

7 Printer: If you need the lot number or some logo or bar code on bag you can add the printer machine or label stick machine. You can edit the content like word or excel on the independent printer interface screen.

8 End Weigher : If you worried about the weight per bag then you can add this device so it will get rid of bag which is out of your weight tolerance . For example , if you set in 1000g and tolerance is 2g ,then when the finished bag which is 1003g moved through the end weigher , it will be push aside .

Operating principle & working process
The products come from the production line
→When the products drop into the vibrator with bucket hopper, it will be vibrated out to the conveyor
→ the conveyor will keep sending the product to the weigher until the weigher sending the signal to it.
→the multi heads weigher is for dosing the product and dropping it to the packing machine time by time. It is continuously given the finished signal to the packing machine.
→When the packing machine gets the signal, it will feedback to the weigher and start dropping down the product, then the machine starts drawing down the film, printing the date, sealing, and cutting the package.
→ When the bags made out, they will be transferred out by the finished product conveyor and then to the turn table or the secondary packing.



1. According to screw/special parts sample tailored to the vibration plates with precise count control device, to ensure that every bag is accurate and correct.

2. Adopts pneumatic structure, whole machine is more secure, stable, reliable.
3. Advanced PLC control system and various automatic alarm protection functions, convenient for daily maintenance and reduce wastage.
4. It completes the whole procedure of metering, filling,bagging,date printing, charging(exhausting),counting automatically.
5. Unique design of the packing seal technology, make the sealing nice and strong.

6. Equipped with chain conveyor trailer,it can be feed by manual if the vibration plates is un-workable.

Operating Principle


Firstly, product is transferred to infeed funnel by conveyor, and then distributed to linear vibrator pan by the vibration of top cone. The height of infeed funnel is adjustable by adjusting the supporting bar, which can adjust the thickness of product on the top cone. 


weighing machine

Product is distributed evenly into each linear vibrator pan and then drop into feed hopper by linear vibration. After the weigh hopper finished the previous combination, the feed hopper will drop down the product into weigh hopper by opening the door. 

According to the target weigh, the CPU will combine the weight data received from each weigh hopper, then pick out a closest combination from numerous qualified combination.(As show in chart 3-1-1)
1.The parameters related with the weigh hopper: “AFC”, “Main AMP”, “Lin AMP”, “Average Combination Hoppers”, and “Single Hopper Weigh”. (Details refer to System Setup 6.2)
AFC 0: The bigger of the “Main AMP” and “Lin AMP”, the heavier of the single weigh hopper.
AFC 1:The bigger of the “ Avg Comb HPs”, the lighter of the single weigh hopper.
AFC 2:The bigger of the “Sgl HP Wt”, the heavier of each weigh hopper.
2.The parameters related with the combination: “Optimum”, “Combined Hoppers”
Optimum: Accuracy will be more precise by increasing this value. As show in Chart
3-3-1, if the “Optimum” is 98, the best group (6) will be selected, and then it is unnecessary to combine again.
Combined Hoppers: The pass rate will be better by increasing this value. As show in Chart 3-3-1, if there is no qualified combination and the actual combined hoppers≥ preset “Combined Hoppers”, the product will be enforced to discharge to ensure the machine in continuous running. If the actual combined hoppers< preset “Combined Hoppers”, the machine will wait for the discharged hoppers to re-feed again, and then combine together.
weighing machine

There are four ways to discharge the products to the next equipment.
1.Direct Discharge (Timing Hopper set as 0): Product is directly discharged from the collecting funnel to the next equipment.
2.Timing Hopper Discharge(Timing Hopper set as 1):Product is firstly stored in the timing hopper after discharging from collecting funnel, and then dumped to the next equipment. This function is to collect products and shorten the drop time. As show in Chart 3-4-1

weighing machine

3.Timing Hopper Discharge(Timing Hopper set as 2):Product is firstly stored in the timing hopper after discharging from collecting funnel, and then discharged respectively to the next two equipments according to their dump request signal. This function is full utilizing the high speed of multihead weigher. As show in Chart3-4-2

weighing machine

4 Timing Hopper + Auto-sorting(Timing Hopper set as 3):Product is firstly stored in the timing hopper after discharging from collecting funnel. When the weigh of product is unqualified, the Auto-sorting motor will open the right door to dump them to the unqualified channel. As show in Chart 3-4-3

5 Product Stopper: When the product stopper is installed, it will reduce the products to collide. As show in Chart 3-4-4
