Abstract
A process and a machine for overpacking luggage of users of different transport means and in particular, for airplane passengers. The machine includes a device for forming a packing around each luggage (5), moving the luggage upon a conveyor belt (8) and during its movement, providing the packing in the form of a protecting envelope (16) made of a plastic material, while providing the envelope (16) with an opening extending in front of the handle (6).
Claims14
A machine for wrapping individual pieces of luggage which have different shapes and sizes and are used in different transportation means and in particular for airborne passengers and wherein each said piece of luggage is provided with a carrying handle on one of its lateral surfaces, comprising:
- three endless carriers positioned horizontally and longitudinally;
- means for driving said endless carriers in the same direction;
- said endless carriers including an upstream entrance carrier, an intermediate wrapping carrier and a downstream carrier;
- a vertical and longitudinal plate extending above said upstream entrance carrier, on one side thereof, defining a vertical and longitudinal reference plane, and constituting a lateral stop for the lateral surface, provided with the handle, of each piece of luggage placed flat on said upstream carrier for positioning said luggage on said entrance carrier;
- means for forming, in the space between said upstream entrance carrier and said intermediate wrapping carrier, a vertical transverse curtain formed by at least one sheet of heat-shrinkable material with one edge of said curtain in close proximity to said vertical plate so that said lateral surface provided with the handle positioned against said plate is in close proximity to said one edge of said curtain and with the lateral surface opposite the handle is at a greater distance from the other edge of the curtain;
- said intermediate wrapping carrier comprising means for passing said piece of luggage through the curtain of heat shrinkable material to form a protective tubular envelope around each said luggage, open at its two extremities with a short portion extending laterally on said handle containing surface and a longer portion extending laterally on said opposite surface;
- and
- a shrinking oven tunnel through which passes successive pieces of luggage surrounded by its respective tubular protective envelope, upon said downstream carrier, said tunnel includes means for shrinking the envelope and to overlap it slightly externally relative to the surface of the luggage to which is attached said carrying handle while leaving the handle exposed and for completely shrinking and overlapping said opposite portion for obtaining at the exit of said oven tunnel, after shrinkage of the plastic material, a luggage totally wrapped with the exception of an opening which is formed, during the shrinkage of the heat-shrinkable envelope, on the side where the carrying handle is located and in front thereof.
A process for wrapping individual pieces of luggage which have different shapes and sizes and are used in different transportation and in particular for airborne passengers and wherein each said piece of luggage is provided with a carrying handle on one of its lateral surfaces, and forming around each piece of luggage a protective envelope of plastic material in contact with the external surface of the luggage with the exception of an area left open in order to provide access to the carrying handle, once the protective envelope is positioned around the luggage, comprising:
- providing three endless carriers positioned horizontally and longitudinally and driving the endless carriers in the same direction, the endless carriers including an upstream entrance carrier, an intermediate wrapping carrier and a downstream carrier, a vertical and longitudinal plate extending above the upstream entrance carrier, on one side thereof, defining a vertical and longitudinal reference plane, and constituting a lateral stop for the lateral surface, provided with the handle, of each piece of luggage placed flat on said upstream carrier;
- forming, in the space between the upstream entrance carrier and the intermediate wrapping carrier, a vertical transverse curtain formed by at least one sheet of heat-shrinkable wrapping material with one edge of said sheet curtain being in close proximity to said plate;
- positioning said luggage with said lateral surface provided with the handle against said plate so that said lateral surface is in close proximity to said one edge of said curtain and with the lateral surface opposite the handle is at a greater distance from the other edge of the curtain;
- passing said luggage through said curtain to form from the one sheet of heat shrinkable material, a protective tubular envelope around each luggage, open at its two extremities with a short portion extending laterally on said handle containing surface and a longer portion extending laterally on said opposite surface;
- passing successive pieces of luggage surrounded by its respective tubular protective envelope through a shrinking oven tunnel upon the downstream carrier to shrink the envelope and to overlap it slightly externally relative to the surface of the luggage to which the carrying handle is attached while leaving the handle exposed and completely shrinking and overlapping said opposite surface for obtaining, at the exit tunnel oven, after shrinkage of the plastic material, a luggage totally wrapped with the exception of an opening which is formed, during the shrinkage of the heat-shrinkable envelope, on the side on which the carrying handle is located and in front thereof.
