Abstract
An electrostatic oiling system for use with single blanks in batch systems having an open spray chamber without the need for a negative vacuum chamber. Further, the provided electrostatic oiling system may utilize induction beams and a charge wall that allows for utilization of a smaller vacuum system. Further, the provided electrostatic oiling system may provide variable blank coverage without the need for metered pumps.
Claims19
A method of spraying oil on a surface comprising:
- charging a volume of oil to a first voltage;
- charging at least one spray nozzle to a second voltage;
- charging at least one inductor bar to a third voltage;
- directing an oil spray of the volume of oil from the at least one spray nozzle towards a blank of material having a surface to be oiled via the differences between the first, second, and third voltages;
- moving the blank of material through an oil spray defined by the volume of oil a predetermined speed to coat the surface with an even layer of oil;
- and
- applying a vacuum through at least one slot defined through an exterior of the at least one inductor bar to recover any excess oil not applied to the blank of material when the blank of material is within the oil spray.
