TANK VENTING APPARATUS FOR A PACKAGING MACHINE.

摘要

An apparatus for internally venting a product tank (12) in a packaging machine (10) including a filling tube (16) having a first end (18) extending from a first opening (20) of the product tank (12) and an air collection mechanism (14) having a filling tube opening (24) adapted to receive a second end (22) of the filling tube (16). The air collection mechanism (14) extends below the second end (22) of the filling tube (16). A vent pipe (28) is connected to a second opening (30) of the product tank (12) and to a vent pipe opening (32) in the air collection mechanism (14). The filling tube (16) and the vent tube (28) are separately connected to both the product tank (12) and the air collection mechanism (14). Air pressure, arising from operating the packaging machine (10), is directed from the air collection mechanism (14) through the vent pipe (28) and into the product tank (12). Such air proceeds through the vent pipe (28) and replaces product in the product tank (12) as the product is dispensed into the carton during filling.
