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.
Claims15
A method of oiling a blank comprising:
- moving a blank into a spray zone between an upper spray system having at least one upper inductor bar with a first voltage and a lower spray system having at least one lower inductor bar with the first voltage;
- increasing the first voltage of the at least one upper inductor bar to a second voltage in response to the blank entering the spray zone;
- increasing the first voltage of the at least one lower inductor bar to the second voltage in response to the blank entering the spray zone;
- applying a layer of oil to a top side of the blank with at least one upper spray nozzle of the upper spray system as the blank moves through the spray zone;
- simultaneously applying a layer of oil to a bottom side of the blank with at least one lower spray nozzle of the lower spray system as the blank moves through the spray zone;
- moving the blank out of the spray zone;
- decreasing the second voltage of the at least one upper inductor bar back to the first voltage in response to the blank exiting the spray zone;
- decreasing the second voltage of the at least one lower inductor bar back to the first voltage in response to the blank exiting the spray zone;
- and
- recovering any excess oil from the upper and lower spray nozzles with a vacuum applied through at least one of the at least one upper inductor bar and at least one lower inductor bar.
