Abstract
Abstract A conveyor conveys a row of pairs of cartons to a casing apparatus which marshals the cartons into a tier for positioning into a case. A pivoting mechanism pivots the first pair of cartons at right angles to the conveyor onto a horizontal carrier and a pusher pushes subsequent pairs of cartons transversely from the row onto the conveyor. The pivoting mechanism resiliently retains a pair of cartons during the pivoting operation. The tier of cartons is positioned below a gripping head having clamps actuated simultaneously to grip the cartons upon downward movement of the gripping head. The gripping head has one pair of clamps at right angles to the remaining clamps and a linkage is provided to actuate all of the clamps simultaneously.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
173 words
In an apparatus for casing pairs of cartons within a case, the combination of a frame having a loading table thereon, a conveyor mounted on said frame for feeding a row of cartons in a predetermined direction onto said loading table, means for forming a tier of a predetermined number of pairs of cartons including a pusher mounted on said frame and before which said Row of cartons passes, a horizontally reciprocable carrier mounted on said frame in position to receive pairs of cartons pushed by said pusher, means for actuating said pusher to push a pair of cartons transversely of said row a predetermined distance onto said carrier, vertically reciprocable gripping-head means mounted on said frame, and means actuating said carrier for moving a tier of a predetermined number of pairs of cartons to a point beneath said gripping-head means wherein the improvement comprises means associated with said tier forming means for pivoting a pair of cartons onto said carrier to a position at right angles to the direction of said conveyor.
Claim 2
Dependent Claim
173 words
In an apparatus for casing pairs of cartons within a case, the combination of a frame having a loading table thereon, a conveyor mounted on said frame for feeding a row of cartons in a predetermined direction onto said loading table, means for forming a tier of a predetermined number of pairs of cartons including a pusher mounted on said frame and before which said Row of cartons passes, a horizontally reciprocable carrier mounted on said frame in position to receive pairs of cartons pushed by said pusher, means for actuating said pusher to push a pair of cartons transversely of said row a predetermined distance onto said carrier, vertically reciprocable gripping-head means mounted on said frame, and means actuating said carrier for moving a tier of a predetermined number of pairs of cartons to a point beneath said gripping-head means wherein the improvement comprises means associated with said tier forming means for pivoting a pair of cartons onto said carrier to a position at right angles to the direction of said conveyor.
Claim 3
Dependent Claim
21 words
In an apparatus as claimed in claim 1 wherein said pivoting means comprises means for resiliently retaining said pair of cartons.
Claim 4
Dependent Claim
27 words
In an apparatus as claimed in claim 1 wherein there is a retaining guide for inhibiting radially outward movement of a pair of cartons during pivoting thereof.
Claim 5
Dependent Claim
35 words
In an apparatus as claimed in claim 3 wherein there is an actuating means for said retaining guide to move the retaining guide to an ineffective position after a pair of cartons has been pivoted.
Claim 6
Dependent Claim
45 words
In an apparatus as claimed in claim 1 and comprising means for sequencing the pivoting of said pivoting means to pivot spaced predetermined pairs of cartons from said row, the pairs of cartons between said pivoted pairs being pushed by said pusher onto said carrier.
Claim 7
Dependent Claim
19 words
In an apparatus as claimed in claim 5 and comprising a fluid pressure cylinder for pivoting said pivoting means.
Claim 8
Dependent Claim
30 words
In an apparatus as claimed in claim 2 wherein said resilient retaining means comprises a pair of spaced resilient arms between which the pair of cartons is retained during pivoting.
Claim 9
Dependent Claim
32 words
In an apparatus as claimed in claim 1 wherein said gripping-head means comprises a plurality of clamps corresponding to the plurality of pairs of pushed cartons and said pair of pivoted cartons.
Claim 10
Dependent Claim
25 words
In an apparatus as claimed in claim 8 wherein the clamps for said pivoted pair of cartons are at right angles to said other clamps.
Claim 11
Dependent Claim
22 words
In an apparatus as claimed in claim 9 and comprising means on said gripping-head means for actuating all of said clamps simultaneously.
Claim 12
Dependent Claim
48 words
In an apparatus as claimed in claim 10 and comprising an actuating cylinder on said gripping-head means, linkage connected to said actuating cylinder to close the clamps for the pushed cartons upon actuation of the cylinder, and means interconnecting said pushed carton clamps and said pivoted carton clamps.
Claim 13
Dependent Claim
52 words
In an apparatus as claimed in claim 9 and comprising a plurality of pairs of pivotable parallel rods, on said gripping-head means, the clamps for the pushed cartons being attached to said rods, and linkage means for pivoting each rod of a pair in opposite direction to close and open the clamps.
Claim 14
Dependent Claim
53 words
In an apparatus as claimed in claim 12 and further comprising a fixed bar on said gripping-head means at right angles to said parallel rods, an additional rod parallel to said fixed bar and having a clamp thereon engageable with said bar in the clamping position to clamp said pair of pivoted cartons.
Claim 15
Dependent Claim
41 words
In an apparatus as claimed in claim 13 and comprising linkage means between one of said pairs of parallel rods and said additional rod to actuate said additional rod simultaneously with said parallel rods whereby all of said clamps operate together.
Claim 16
Dependent Claim
26 words
In an apparatus as claimed in claim 1 and further comprising means supporting said case beneath said gripping-head means to receive a tier of said cartons.
