Counting and Packing Machine for Nucleic Acid Reagents Bottles

Customer’s Requirement

Product: nucleic acid reagents bottles

Qty：20~25pcs/packet

The weigth is 2,8 gramm (0.5 ml bottle) -3,2 gramm(0.7 ml bottle).- 0.5-0.6-0.7 ml/pc

Required speed: 20 packets per min

We have bought the machine from another company, unfortunately, its performance is not good. And we need to buy a second machine. The bottles are the same as I have asked in the last inquiry.

Please check if you can help us to find a suitable machine. We have the below problems with another machine

Low capacity: 10 packets per minute, 25 bottles， with 4 hoppers

There is no pause button and can’t change the parameters in any way, can’t add length to the package, can’t work with the quantity of packaging, the setup becomes more complicated due to this. After pressing the stop button, the count of finished packages is lost, the count of already filled bottles is also lost, and the conveyor line has to be emptied. The film constantly moves to the side, we have to correct it. The monitor keeps turning off.

Our solution：

Option 1

4~6 hoppers together with packing machine without middle conveyor. similar to the YouTube video below. your bottle a little longer we consider it will easy stuck when following into our small packing machine. We suggest no middle conveyor because, the middle conveyor’s max speed is about 8~10 bags per minute without the max speed is about 24 bags per minute, if the hopper counting speed is enough for the packing machine speed. we set 20~25 pcs for each hopper, so 4 or 6 hoppers are counting together, when one hopper finished counting one bag qty then the 20~25 pcs will fall into the packing store box waiting for the packing machine to fill into the bag, so the hopper can always keep counting, and packing machine always keep make and sealing bag. the speed needed to test with your exact products. The disadvantage is the machine will be higher if without a conveyor, so means your staff need to add bottles with a ladder.

Please see below one of our similar cases

6 hoppers with a big packing machine, machine height to be about 2.2M. The machine speed is about 8 bags, 100 pcs per bag, screw length is about 80mm.

6 hoppers with a small packing machine, machine height to be about 1.6M

Option 2

weigher

The other option is weigher, please see the below video, the same product as yours , speed is about 20 bags per min, 14head 2.5L， with a second weigher before packing, and finished end weigher, accuracy to be 100%, simensce PLC，

For the below information, please see our suggestion

Low capacity: 10 packets per minute, 25 bottles.

we think that adding a conveyor,

There is no pause button

we have below 2 top buttons,

can’t change the parameters in any way, can’t add length to the package, can’t work with the quantity of packaging, the setup becomes more complicated due to this.

Generally, if the PLC of the machine is independently designed by the factory, it can be changed. If it is a single-chip microcomputer, it generally cannot be changed.

Our machine able to change the bag length , machine speed, quantity per bag , if you interested in pls see the below operation video.

Each hopper is controled indenpently , you can turn on or off on touch screen, change the quantity , the bag length

And after pressing the stop button, the count of finished packages is lost, the count of already filled bottles is also lost, and the conveyor line has to be emptied. The film constantly moves to the side, we have to correct it. The monitor keeps turning off.

For our machine, if you press the 1 above red stop button then machine will stop after finished one package, if you press 2 emergency button then the effect like your information, machine can’t continue working if press running button again. our machine can qutomatically clean the hopper remaiing parts and send to packing machine, you only need to press one clean button.

Q1Could you please prepare more detailed video?

From the below video , you can see there are 6 hoppers counting the one kind screw at the same time, customer required 100 pcs per bag, screw length is 80mm, and our this machine speed is about 7~8 bags per min. we set one hopper for one bag qty, for your bottles, we set 25 or 20 pcs for each hopper, so the 6 hopper will counting the bottles at the same time when one hopper finished counting 25 first then it will fall into packing machine for sealing bag and at the same time the other hopper also finished 25 pcs counting then it will store in the box which marked 123456 you can see inthe picture, waiting for the packing machine sealing the 25 pcs in turns , and at the same time hopper always counting the bottles, and packing machine always sealing the bag , which the store box always wating for falling and packing in turns. Sealing bag takes 2.4s then means the speed is 60/2.4=25 bags per minute, as long as hopper counting speed is enough, if without conveyor then we suggest add 6 hopper most , as it will be very higher. from your bottle size and our previous case, your speed would be about 18 bags per min. we can only double confirm afer test with your examly sample.

For example, a bottle hopper counting 25 pcs bottles, takes about 20s, but the packing machine only takes 2s to seal the bag, so the 18s is waste for the packing machine. So we try to add more hoppers and one store box for each hopper before following into the packing machine, we can turn on 6 hoppers at the same time so hoppers can count the bottles at the same time when one hopper is finished counting25 pcs then the 25 pcs bottles fall into store box first waiting for the packing machine sealing. So it becomes a packing machine always to working as there always 25 pcs bottles waiting for sealing in store box.

Q2Is this line more compact? And each bowl counts separately?

yes, without conveyor so it will be smaller but higher. pls see below middle conveyor we refer to. if add middle conveyor then machine max speed is 8~10 bags per min due the conveyor cycle time. so we suggest no conveyor like our above video, machine max speed 24 bags per min.

with conveyor

without conveyor

Q3Will be capacity 20 bags per minute?

From below video , our machine speed is 24 bags per min.but your products longer than this customer products so we need to test with your exactly sample, we think about 18 bags per min.
