Powder Sieving
PROBLEM
Rewinding bags onto a roll the static charges built up on the material will cause the roll to balloon. This makes the roll larger and less attractive, increasing the box size and transportation cost more expensive.
SOLUTION
Using positive and negative charge bars on either side of the bags, removes any trapped air within the bag, while the positive charges are attracted to the negative side during rewinding, helping to prevent the roll unwinding when ejected from the rewind.
Using directly coupled 993 generator bars, one of the generators can be set to spark/perforation detection. This can produce a voltage output signal to the PLC to count the perforations (bags) as they are rewound onto the roll.
