Abstract

Official abstract text for this publication.

An apparatus for self cleaning of a photo eye sensor in a machine includes at least one air nozzle disposed in air discharge communication with a surface to be cleaned of the photo eye sensor. The air nozzle is in air flow communication with air exhaust from an air cylinder of a component of the machine. Related, corresponding, or associated methods for self cleaning a photo eye sensor in a machine are also disclosed.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for self cleaning a photo eye sensor in a packaging processing machine having an air source actuator cylinder powered by compressed air to move a component of the machine, the method comprising: generating a waste exhaust air from reciprocating the actuator cylinder during use of the component of the machine; conveying the waste exhaust air from the actuator cylinder of the machine to at least one air nozzle disposed in air discharge communication with a surface to be cleaned of the photo eye sensor, and applying the waste exhaust air onto the surface to be cleaned of the photo eye sensor to remove debris from the surface. 2. The method of claim 1 wherein the waste exhaust air is conveyed from the actuator cylinder to the at least one air nozzle via one or more conduits and with a solenoid valve disposed in the air flow communication between the actuator cylinder and the at least one air nozzle. 3. The method of claim 1 wherein waste exhaust air from a single actuator cylinder of a component of the machine is conveyed to a plurality of said air nozzles.
