Abstract
A case packing apparatus for loading articles into a case that includes two or more airbags adapted to be positioned above the case; a vacuum reservoir positioned in fluid communication with the airbags; and a supply of compressed gas positioned in fluid communication with the airbags.
Claims14
A case packing apparatus for loading articles into a case, the apparatus comprising:
- two or more airbags adapted to be positioned above the case;
- a manifold connecting the airbags;
- a vacuum reservoir positioned in fluid communication with the manifold;
- a valve positioned between the vacuum reservoir and the manifold;
- a supply of compressed gas positioned in fluid communication with the manifold;
- and
- a solenoid valve positioned between the supply of compressed gas and the vacuum reservoir, wherein the solenoid valve is directly connected to the vacuum reservoir, wherein the solenoid valve actuates the valve, with vacuum pressure from the vacuum reservoir, to open and remove gas from the two or more airbags through the valve into the vacuum reservoir, and wherein the solenoid valve is also directly connected to the supply of compressed gas via a regulator, wherein the solenoid valve actuates the manifold, with the supply of compressed gas, to open and inflate two or more airbags with gas.

A case packing apparatus for loading articles into a case, the apparatus comprising:
- a conveyor for conveying articles toward the case;
- two or more airbags positioned above the case;
- a manifold connecting the airbags;
- a vacuum reservoir positioned in fluid communication with the manifold;
- a vacuum pump connected with respect to the vacuum reservoir, wherein the vacuum pump is configured to continuously operate;
- a supply of compressed gas positioned in fluid communication with the manifold;
- a diaphragm valve positioned between the vacuum reservoir and the manifold;
- a check valve positioned between the diaphragm valve and the manifold;
- and
- a solenoid valve positioned in direct communication with:
- the vacuum reservoir, the check valve in fluid communication with the manifold, and a regulator in fluid communication with the supply of compressed gas;
- wherein the solenoid valve is configured to open and remove gas from the two or more airbags through the diaphragm valve into the vacuum reservoir with vacuum pressure from the vacuum reservoir;
- wherein the solenoid valve is also configured to open and inflate two or more airbags with gas through the manifold with the regulator from the supply of compressed gas;
- and
- wherein the check valve is configured to hold at least a portion of the supply of compressed gas in the manifold while the solenoid valve actuates at least one of the vacuum reservoir and the regulator.
