The ThunderIon anti-static bar introduced by Simco at K-show last year has been further developed. The long range ionisation is achieved by a combination of high voltage, pulsed DC and a low frequency. Some of the features include replacable emitters and low voltage input of 24V DC LED indication.
For cases when more than one anti-static bar is required, the ThunderIon is supplied with a central Control Module which provides power and control for up to four anti-static bars. A yellow LED indicates that the bar is switched on, while a red LED indicates that a fault has been detected.
The Simco anti-static bars can be used in a variety of applications including sheeting, slitting, rewinding and bag making.
The Simco anti-static bars can also enable static-free rewinding. At the rewind of film extrusion lines, static results in electrical discharge causing shocks to employees, dust attraction and incorrect rewinding. The Simco bars are said to provide the needed neutralisation at a distance without air support.
Another application for the anti-static bars is bag making, where it is claimed to enable high speed static-free bag production on wicket bag making machines.
Also, the Simco Long Range anti-static bars, just after the slitting operation, are said to direct the ionisation at the film. “Static charges are eliminated during the slitting process, preventing fragments from being retracted to the film. As a result, neutralised materials stay clean and dust-free, reducing slowdowns and rejected rolls, and improving overall product quality,” says the company.
