Evalcan Machinery & Equipment Co.,Ltd is one of the top level China fasteners counting packing machine manufacturers and suppliers, we are always able to provide customers with cheap fasteners counting packing machine products. Welcome to buy low price products from us.
1-Machine principle and composition
This way is suitable for less quantity(1-12pcs/bag) packing, using the fixed distance between the fittings, and adjust the baffle to this distance, to make the count.
This way is not suited to the large counting, and has a limit for different shape of fittings, we have abandon this method.
2-Optic fiber counting
This way is used the optic fiber to make the counting, using the multi-function of the optical fiber, such as shake proofing, time delay etc. to count the different kinds of fittings.
There is not limit of the counting, it can count the fittings from 1-99999, by the PLC control, the quantity can be adjusted easily.
Also using different setting of optic fiber, most of the fittings can be counted.
Currently, we use this method for all of our machine.
3-Weighing and counting system.
This method is based on the optic fiber counting.
Because the optic fiber counting shall be cooperated with the vibration hopper(to sort and feed the fittings to pass through the optic fiber one by one), and the speed of the vibration hopper is limited. For big quantity counting, the speed will a little slow. But we found for big quantity fittings the first 80-90% fittings are no need to counted one by one, so we use the weighing system to scale the first 80-90% fittings, and detect the exact quantity by PLC, then add the balancing fittings by optic fiber counting.
This method is special for big quantity counting, usually more than 30pcs/bag.
The machine is mainly composited by the following terms:
This system is a pure counting system, using optical fiber counting, there are four hoppers can count and pack different fittings.
The whole systems are controlled by PLC, and there are three different procedures can be chosen:
A-Packing the single fittings in one bag
A1-Only run one vibration hopper
Just select the vibration hopper you want to use, and press it“on”in the touch screen.
A2-Run all the vibration hoppers.
Because if we pack the single fittings per bag, and only run one vibration hopper, the other hoppers will be stopped, that will waste the production capacity.
So in our procedure, the machine supports to count different fittings in different bags at the same time. The bag length can be set differently.
As the above interface, just as the different buffer no. on the touch screen, the four hoppers will work together and pack different fittings in different bag sizes.
If you want to pack different fittings in one bag, you shall start the hoppers on the touch screen and then set the second buffer no. as “0”, the machine will mix different fittings in one bag.
3-The other features of the machine
a. Controlled by PLC, easy to operate
b. Adopting optical fiber counting method, all the parameter setting and quantity change is set on the touch screen.
c. The machine have autodiagnosis function, when the malfunction is happened,the machine will give an alarm or stop(optional by buyer). And there are some scram buttons on the machine.
d. Can achieve automatic disposing, counting, measuring, filling and packing. The counting quantity is adjusted freely, and the packing quantity is displayed on the screen, easy to calculate the production capacity.
e. Every counting hopper can be opened or stopped according to the adjusting of the production. And every dangerous part have safety protecting device
L20-200mm W20-150mm(as 240)
1-30bags/min(5-70bags/min for packing machine)
BOPP/CPP, NY/CPP etc.
For pure counting the accuracy is almost 100%, for our test the unqualified bag is less than 0.03%
