Abstract
Abstract The invention as herein illustrated is for adjusting the spacing between and the longitudinal direction of conveyors on a layboy transmitting multiple out cuts from a rotary die cutter, thereby to separate the sheets laterally before they are transmitted to a stacker, and also varying the speed of the conveyors of the layboy in relation to the speed of the conveyor belts on the stacker to obtain longitudinal separation of the sheets, thereby to permit multiple stacks to be made simultaneously without the edges of one stack inter-leaving with one another.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
250 words
In a layboy for transferring sheets from one machine to another, a frame between the machines, conveying means on the same frame having a receiving end adjacent to one machine and a delivery end adjacent to the other machine, said conveying means including a plurality of conveyors side by side in horizontal registry and longitudinal with respect to said machines and being spaced transversely from one another to carry sheets from said receiving end to said delivery end, releasable means to hold each of said conveyors in adjusted spaced positions, adjustable mounting means to adjustably support one end of said conveyors, and means to drive said conveyors, each conveyor including a longitudinal rigid arm extending from end to end of the conveyor, a pulley at each end of said arm, said means to drive said conveyors including a transverse drive shaft extending through said adjustable mounting means, each pulley at said one end being a drive pulley and being connected to said drive means at the respective mounting means, said mounting means being adjustable on said shaft, a conveyor belt played around said pulleys on each arm, each belt moving longitudinally around and above and below said arm in a substantially perpendicular plane of said arm, said releasable holding means including a transverse support member on said frame for said arms, and releasable coacting means between an intermediate portion of each arm and said transverse support member to pivotably hold said arm in adjusted position along said transverse support member.
Claim 2
Dependent Claim
250 words
In a layboy for transferring sheets from one machine to another, a frame between the machines, conveying means on the same frame having a receiving end adjacent to one machine and a delivery end adjacent to the other machine, said conveying means including a plurality of conveyors side by side in horizontal registry and longitudinal with respect to said machines and being spaced transversely from one another to carry sheets from said receiving end to said delivery end, releasable means to hold each of said conveyors in adjusted spaced positions, adjustable mounting means to adjustably support one end of said conveyors, and means to drive said conveyors, each conveyor including a longitudinal rigid arm extending from end to end of the conveyor, a pulley at each end of said arm, said means to drive said conveyors including a transverse drive shaft extending through said adjustable mounting means, each pulley at said one end being a drive pulley and being connected to said drive means at the respective mounting means, said mounting means being adjustable on said shaft, a conveyor belt played around said pulleys on each arm, each belt moving longitudinally around and above and below said arm in a substantially perpendicular plane of said arm, said releasable holding means including a transverse support member on said frame for said arms, and releasable coacting means between an intermediate portion of each arm and said transverse support member to pivotably hold said arm in adjusted position along said transverse support member.
Claim 3
Dependent Claim
19 words
The layboy specified in claim 1, and each of said pulleys having peripheral grooves to confine said belt therein.
Claim 4
Dependent Claim
80 words
The layboy specified in claim 1, and said adjustable mounting means including an element on the end of each arm adjacent said driving pulley, said element being adapted to rotatably and slideably hold said driving pulley on said drive shaft, and manipulable means to apply force to said element to adjust the angle of said element to correspond to the angular adjustment of the arm and to slide said driving pulley on said drive shaft into the corresponding adjusted position.
Claim 5
Dependent Claim
101 words
The layboy specified in claim 1, and said adjustable mounting means including a bearing element on the end of each arm, self-aligning bearing means in said element and on said drive shaft, being adapted to rotatably and slideably hold said driving pulley on said drive shaft, and manipulable means to apply force to said element and self-aligning bearing means to adjust the angular position of said element relatively to said self-aligning bearing and to said driving pulley to correspond to the angular adjustment of the arm, thereby to slide said driving pulley on said drive shaft into the corresponding adjusted position.
Claim 6
Dependent Claim
45 words
The layboy specified in claim 4, and said element being a U-shaped brace, said self-aligning bearing means being a self-aligning bearing in each leg of said U-shaped brace, whereby said element is self-adjustable to the angular adjustment of the arm relatively to the driving pulley.
Claim 7
Dependent Claim
45 words
The layboy specified in claim 5, and a hub on each side of said driving pulley engaged by the inner race of said self-aligning bearings to be held in coacting relation to the respective belt in all adjusted positions of said arm and said element.
Claim 8
Dependent Claim
57 words
The layboy specified in claim 1, and said releasable co-acting means including retaining grooves on said transverse support member, grooved members on the adjacent intermediate portions of the respective arms interlocking with the respective grooves of said transverse support member, and manipulable means to lift said arms out of engagement from said support member for transverse adjustment.
Claim 9
Dependent Claim
110 words
The layboy specified in claim 1, and each conveyor including a pair of arms, one arm spced substantially above the other, said drive pulley being at the delivery end of each arm connected to said driving means, and means on the upper arm to urge the belt thereof toward the belt on the lower arm to hold said sheets carried between the adjacent portions of said belts, and separate transverse support members for the upper arm and for the lower arm, each support member being adjacent the intermediate portion of the respective arms, and releasable co-acting means between the intermediate portion of each arm and the adjacent transverse support member.
Claim 10
Dependent Claim
42 words
The layboy specified in claim 8 and brush means extended from the upper transverse support member toward the lower transverse support member in brushing contact with the sheet carried between said conveyor belts for brushing the surfaces of the sheets carried thereunder.
Claim 11
Dependent Claim
32 words
The layboy specified in claim 9, and pneumatic means supported on said upper support member adjacent said brush means to direct a cleaning airflow on to said sheets carried by said conveyors.
Claim 12
Dependent Claim
55 words
The layboy specified in claim 1, and said one end being the delivery end of said conveyors, the machine at said delivery end being a sheet stacker, guide means supported on said frame adjacent the delivery end of said conveyors and extended over said stacker to guide said sheets from said conveyors onto said stacker.
