Claim 1
Independent Claim
309 words
In apparatus for sequentially transferring and aligning panel-like members, (a) a pick-up station supporting a stack of panel-like members to be sequentially transferred and aligned, (b) a discharge station for receiving said panel-like members after transfer and alignment thereof, (c) a primary carriage mounted for linear movement selectively to said pick-up station and to a position adjacent said discharge station, (d) at least one extensible secondary carriage carried by said primary carriage and rotatable about a vertical axis selectively to a transport position and to an aligned position and being movable linearly relative to said primary carriage selectively to an extended position and to a retracted position, (e) a pick-up head carried by said secondary carriage and adapted for rotation therewith, (f) means to move said secondary carriage and the pick-up head carried thereby in a vertical direction selectively to an upper transport position and to a lower pick-up and discharge position, (g) means to stop linear movement of said primary carriage prior to its reaching said discharge station, with said secondary carriage being movable toward said extended position after movement of said primary carriage is stopped, (h) alignment stop means at said discharge station in position to engage at least one edge of said panel-like member as it is transferred in response to movement of said secondary carriage to said extended position to impart rotation to said panel-like member being transferred and its secondary carriage about said vertical axis from said transport position to said aligned position and to correctly position at least one edge of said panel-like member and thus align any misaligned panel-like member being transferred prior to discharge thereof at said discharge station, and (i) means to return said secondary carriage to said retracted position and to said transport position after discharge of said panel-like member being transferred and before returning to said pick-up station.
Claim 2

In apparatus for sequentially transferring and aligning panel-like members, (a) a pick-up station supporting a stack of panel-like members to be sequentially transferred and aligned, (b) a discharge station for receiving said panel-like members after transfer and alignment thereof, (c) a primary carriage mounted for linear movement selectively to said pick-up station and to a position adjacent said discharge station, (d) at least one extensible secondary carriage carried by said primary carriage and rotatable about a vertical axis selectively to a transport position and to an aligned position and being movable linearly relative to said primary carriage selectively to an extended position and to a retracted position, (e) a pick-up head carried by said secondary carriage and adapted for rotation therewith, (f) means to move said secondary carriage and the pick-up head carried thereby in a vertical direction selectively to an upper transport position and to a lower pick-up and discharge position, (g) means to stop linear movement of said primary carriage prior to its reaching said discharge station, with said secondary carriage being movable toward said extended position after movement of said primary carriage is stopped, (h) alignment stop means at said discharge station in position to engage at least one edge of said panel-like member as it is transferred in response to movement of said secondary carriage to said extended position to impart rotation to said panel-like member being transferred and its secondary carriage about said vertical axis from said transport position to said aligned position and to correctly position at least one edge of said panel-like member and thus align any misaligned panel-like member being transferred prior to discharge thereof at said discharge station, and (i) means to return said secondary carriage to said retracted position and to said transport position after discharge of said panel-like member being transferred and before returning to said pick-up station.
Claim 3
Dependent Claim
37 words
Apparatus for transferring and aligning panel-like members as defined in claim 1 in which said primary carriage is mounted for movement along an elongated guide member which extends linearly between said pick-up station and said discharge station.
Claim 4
Dependent Claim
55 words
Apparatus for transferring and aligning panel-like members as defined in claim 1 in which said means to move said secondary carriage in a vertical direction comprises a fluid pressure operated extensible unit carried by said primary carriage and rotatably connected to said secondary carriage to permit rotation of said secondary carriage about said vertical axis.
Claim 5
Dependent Claim
23 words
Apparatus for transferring and aligning panel-like members as defined in claim 3 in which said extensible unit is a piston and cylinder assembly.
Claim 6
Dependent Claim
28 words
Apparatus for transferring and aligning panel-like members as defined in claim 3 in which said extensible unit is rotatably connected to said secondary carriage by a rotary bearing.
Claim 7
Dependent Claim
53 words
Apparatus for transferring and aligning panel-like members as defined in claim 1 in which said secondary carriage is moved selectively to said extended position and to said retracted position by a fluid pressure operated extensible unit and releasable brake means retains said secondary carriage selectively in said extended position and said retracted position.
Claim 8
Dependent Claim
26 words
Apparatus for transferring and aligning panel-like members as defined in claim 6 in which said fluid pressure operated extensible unit is a piston and cylinder assembly.
Claim 9
Dependent Claim
35 words
Apparatus for transferring and aligning panel-like members as defined in claim 1 in which said means to stop linear movement of said primary carriage prior to its reaching said discharge station is a limit switch.
Claim 10
Dependent Claim
60 words
Apparatus for transporting and aligning panel-like members as defined in claim 1 in which said alignment stop means comprises at least one stop member in position to engage a leading edge of a misaligned panel-like member being transferred and impart rotary movement thereto from said transport position to said aligned position as said secondary carriage moves toward said extended position.
Claim 11
Dependent Claim
30 words
Apparatus for transferring and aligning panel-like members as defined in claim 9 in which releasable brake means retains said secondary carriage selectively in said transport position and said aligned position.
Claim 12
Dependent Claim
96 words
Apparatus for transporting and aligning panel-like members as defined in claim 9 in which two of said extensible secondary carriages are carried by said primary carriage with one said secondary carriage being movable in a linear direction at an angle relative to the direction of movement of the other secondary carriage so that said leading edge and an edge adjacent thereto of a misaligned panel-like member engage said stop means to impart rotary movement to each said secondary carriage to its aligned angular position and to correctly position said leading edge and said edge adjacent thereto.
Claim 13
Dependent Claim
35 words
Apparatus for transporting and aligning panel-like members as defined in claim 11 in which said one secondary carriage is movable in a linear direction perpendicular to the direction of movement of said other secondary carriage.
Claim 14
Dependent Claim
109 words
Apparatus for transferring and aligning panel-like members as defined in claim 1 in which said means to return said secondary carriage to said transport position before returning to said pick-up station comprises, (a) an elongated arm carried by said secondary carriage and extending in the direction of travel of said secondary carriage, and (b) a generally V-shaped member mounted in the path of movement of said elongated arm as it approaches said pick-up station with the sides of said V-shaped member flaring outwardly toward said discharge station so that movement of said elongated arm within the confines of said V-shaped member moves said secondary carriage to said transport position.
Claim 15
Dependent Claim
32 words
Apparatus for transferring and aligning panel-like members as defined in claim 13 in which a roller-like member is carried by said elongated arm in position to move inwardly of said V-shaped member.
