Abstract
Abstract An L-shaped member is used for placing horizontal stacks of glass in a substantially vertical position in an L-shaped frame such as a pallet or an L-skid. The glass is transferred from a packing machine by a roller conveyor to the L-shaped member. The L-shaped frame is placed upside down around the glass and the member is rotated between about 91* and 100* so that the glass is in a substantially vertical position resting on edge in the Lshaped frame.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
147 words
An automatic glass packing system comprising: an endless stacking conveyor-belt line having a plurality of stations, means for releasing the glass at a suitable station, means for stacking said glass at said stations, means for moving said glass stacks transversely of said conveyor-belt line, and a glass turnover and packing device for receiving said glass stacks from the moving means comprising: a carriage, an L-shaped member having a first section and a second section extending in a direction that is approximately normal to said first section, pivot means on said member for connecting said member to said carriage, means for rotating said member about an angle of approximately 90* from a position wherein said first section extends approximately horizontally to another position wherein said first section extends approximately vertically, and means for preventing the glass from falling off of said L-shaped member due to a gravitational effect.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
33 words
An automatic packing system as set forth in claim 1 wherein said means for preventing the glass from falling is a means for limiting the angle of rotation to within 91* and 100*.
Claim 4
Dependent Claim
27 words
An automatic packing system as set forth in claim 2 wherein said means for preventing the glass from falling limits the angle of rotation to about 95*.
Claim 5
Dependent Claim
22 words
An automatic packing system as set forth in claim 1 wherein means are provided for moving said device along a desired path.
Claim 6
Dependent Claim
18 words
An automatic packing system according to claim 4 wherein said means for moving said carriage are powered wheels.
Claim 7
Dependent Claim
46 words
An automatic packing system as set forth in claim 1 wherein the first section of said member has powered rolls for moving a stack of glass sheets across said member, whereby the glass extends from adjacent one side to adjacent another side of said first section.
Claim 8
Dependent Claim
28 words
An automatic packing system as set forth in claim 6 wherein a movable section is provided on the second section of said member to take up excess gaps.
Claim 9
Dependent Claim
53 words
An automatic packing system as set forth in claim 7 wherein said movable section has additional powered rolls, each of said additional powered rolls extending from adjacent said one side to adjacent said another side of said member for moving said stack of glass sheets off the end of said movable roller section.
Claim 10
Dependent Claim
33 words
An automatic packing system as set forth in claim 8 wherein said rolls on said first section are in a plane that is oriented 90* from the plane occupied by said additional rolls.
Claim 11
Dependent Claim
27 words
An automatic packing system as set forth in claim 9 wherein a pressure switch is provided on said movable section to protect the glass from being damaged.
Claim 12
Dependent Claim
29 words
An automatic packing system as set forth in claim 1 wherein an L-shaped frame member is provided on said first portion of said turnover device for packaging said glass.
