Abstract
Abstract A collating conveyor arrangement in which two conveyors have closely spaced parallel sections provided with dam mechanisms for forming articles into groups and alternately releasing the groups. An on-edge transfer conveyor is pivotally positioned above the parallel conveyor sections to selectively extend obliquely across one of the parallel sections to direct the groups formed on one conveyor into spaces between the groups formed on the other conveyor.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
327 words
A collating conveyor arrangement comprising in combination first and second conveyors having parallel sections separated by a space, a third conveyor above said parallel sections of said first and second conveyors and positioned on-edge to direct articles obliquely from one of said parallel conveyor sections to the other, first and second dam mechanisms upstream of said on-edge conveyor for respectively controlling the flow of articles along said first and second conveyors, and means for operating said dam mechanisms to feed groups of articles alternately down said first and second conveyors toward said on-edge conveyor, said on-edge conveyor having a first end positioned above said space between said first and second conveyors, and said on-edge conveyor being pivoted about a vertical axis extending into said space for movement of the conveyor between a first position extending diagonally across first conveyor and a second position extending diagonally across said second conveyor, wherein said dam mechanisms include first and second pivoted arm assemblies mounted respectively above said first and second conveyors, said arm assemblies each including a roller mounted at the free end thereof, said arm assemblies being moveable between a lower position and an upper position, in said lower position said roller being positioned to engage the leading edge of and article on the conveyor associated with that arm and thus form a group of articles having a continuous top surface, in said upper position said roller is moved out of engagement with the leading edge of the engaged article to allow the group to move down the conveyor, and wherein said dam operating means includes first and second cam means for periodically raising said first and second arm assemblies respectively to said upper position briefly to release the group of articles and then lower the assembly to place the roller onto the continuous top surface of the group, whereby the assembly drops to the lower position when the last article in the group formed moves past the roller.
Claim 2
Dependent Claim
327 words
A collating conveyor arrangement comprising in combination first and second conveyors having parallel sections separated by a space, a third conveyor above said parallel sections of said first and second conveyors and positioned on-edge to direct articles obliquely from one of said parallel conveyor sections to the other, first and second dam mechanisms upstream of said on-edge conveyor for respectively controlling the flow of articles along said first and second conveyors, and means for operating said dam mechanisms to feed groups of articles alternately down said first and second conveyors toward said on-edge conveyor, said on-edge conveyor having a first end positioned above said space between said first and second conveyors, and said on-edge conveyor being pivoted about a vertical axis extending into said space for movement of the conveyor between a first position extending diagonally across first conveyor and a second position extending diagonally across said second conveyor, wherein said dam mechanisms include first and second pivoted arm assemblies mounted respectively above said first and second conveyors, said arm assemblies each including a roller mounted at the free end thereof, said arm assemblies being moveable between a lower position and an upper position, in said lower position said roller being positioned to engage the leading edge of and article on the conveyor associated with that arm and thus form a group of articles having a continuous top surface, in said upper position said roller is moved out of engagement with the leading edge of the engaged article to allow the group to move down the conveyor, and wherein said dam operating means includes first and second cam means for periodically raising said first and second arm assemblies respectively to said upper position briefly to release the group of articles and then lower the assembly to place the roller onto the continuous top surface of the group, whereby the assembly drops to the lower position when the last article in the group formed moves past the roller.
Claim 3
Dependent Claim
40 words
Apparatus according to claim 1 including a fourth conveyor in said space between said first and second conveyors and beneath said third conveyor, said fourth conveyor being driven at a speed equal to that of the first and second conveyors.
Claim 4
Dependent Claim
111 words
Apparatus according to claim 2 wherein said third conveyor includes a shaft extending vertically between said first and second conveyors, means for driving said shaft, an arm having one end pivotally mounted on the upper end of said shaft and having a free end, first pulley means mounted on said shaft below said arm to rotate with said shaft, second pulley means mounted on the free end of said arm, a conveyor belt mounted on said first and second pulley means to extend horizontally just above the surface of the first, second and third conveyors, and means for selectively locking said third conveyor in either said first or said second position.
Claim 5
Dependent Claim
46 words
Apparatus according to claim 3 wherein each of said arm assemblies includes horizontal shaft means above the associated conveyor, a pair of parallel arms each pivoted on said shaft means and having a free end, said roller being positioned between the free ends of said arms.
Claim 6
Dependent Claim
81 words
Apparatus according to claim 4 wherein each of said first and second dam operating cam means includes a cam mounted on the shaft of the associated arm assembly for rotation therewith, means for driving said arm assembly shaft to rotate said cam, a lever pivoted at one end and attached to the associated arm assembly at the other end, and a cam follower mounted on said lever and engaging said cam to move said assembly between said lower and upper positions.
Claim 7
Dependent Claim
20 words
Apparatus according to claim 4 wherein said lever is connected to said arm assembly by means of an adjustable linkage.
Claim 8
Dependent Claim
17 words
Apparatus according to claim 5 wherein said first and second arm assemblies share a common horizontal shaft.
