Method of removal of electrostatic charges from trays used for transporting rod shaped elements, tray protected against negative action of electrostatic field and device for unloading trays filled with rod shaped elements with simultaneous removal of electrostatic charges

摘要

A method of removing electrostatic charges from a tray by supplying pressurized ionized air, first along the bottom of the already turned over tray, and then, when unloading the tray, along its side walls or the inner walls of a compartment. A tray made of dielectric material and protected against negative action of the electrostatic field and having a conducting metal insert provided on the inside of the tray. The insert may have different shapes. A device for unloading compartment trays made of a dielectric material and provided with an ionizer disposed horizontally along the linear transporter, in the zone of feeding of the trays with its nozzles turned in the direction of the inside of the bottom of the tray.
