Abstract
Abstract The present invention relates to apparatus for scroll-shearing strips from a sheet of metal stock imprinted with coatings, such as blanked circular areas for the manufacture of metal caps from sheared strips. The sheets are successively sheared into multiple strips and the strips are oriented and fed to bins all in the same orientation. The feeding of the strips to the bins and orientation thereof is accomplished by gravity feed of the sheared strips by position of the shear point of the sheet to a corresponding conveyor means which automatically orients the strips it receives and dispenses the strips into a bin so that the strips are piled in all bins in like orientation.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
272 words
Apparatus for shearing and handling metal strips from master sheets which include multiple rows of circular article blanks imprinted on at least one surface, comprising a shear means for receiving the master sheets and feeding each through the shear means for cutting the sheet into plural strips, each strip containing multiple rows of said article blanks thereon, a first conveyor means adapted to receive the first and third most forward strips cut from each master sheet, said conveyor means extending to a lateral delivery zone, a receiver bin at said delivery zone supported to receive strips in plural piles, said conveyor means including means for holding said strips thereon at least during part of their movement thereon with said conveyor, said conveyor means having an overhead segment in which the strips are turned end-for-end for delivery to the receiver bin, a second conveyor means adapted to receive the second most forward strip cut from the master sheet, said conveyor delivering the strips at a terminal end thereof and including means for holding the strips thereon for at least a portion of the movement with this conveyor, said second conveyor means extending to the delivery zone for delivery of strips to the receiver bin, a third conveyor means for receiving the fourth most forward strip cut from said master sheet, said conveyor means extending to the delivery zone and including means for holding strips thereon at least during a portion of their movement with said conveyor, said third conveyor means including means for forwardly inverting each of said fourth strips while on the conveyor and prior to their being held by the conveyor.
Claim 2
Dependent Claim
272 words
Apparatus for shearing and handling metal strips from master sheets which include multiple rows of circular article blanks imprinted on at least one surface, comprising a shear means for receiving the master sheets and feeding each through the shear means for cutting the sheet into plural strips, each strip containing multiple rows of said article blanks thereon, a first conveyor means adapted to receive the first and third most forward strips cut from each master sheet, said conveyor means extending to a lateral delivery zone, a receiver bin at said delivery zone supported to receive strips in plural piles, said conveyor means including means for holding said strips thereon at least during part of their movement thereon with said conveyor, said conveyor means having an overhead segment in which the strips are turned end-for-end for delivery to the receiver bin, a second conveyor means adapted to receive the second most forward strip cut from the master sheet, said conveyor delivering the strips at a terminal end thereof and including means for holding the strips thereon for at least a portion of the movement with this conveyor, said second conveyor means extending to the delivery zone for delivery of strips to the receiver bin, a third conveyor means for receiving the fourth most forward strip cut from said master sheet, said conveyor means extending to the delivery zone and including means for holding strips thereon at least during a portion of their movement with said conveyor, said third conveyor means including means for forwardly inverting each of said fourth strips while on the conveyor and prior to their being held by the conveyor.
Claim 3
Dependent Claim
47 words
The apparatus defined in claim 1, wherein the shear means on an initial stroke on each master sheet forms a forward marginal trim strip, and means disposed beneath the shear means to receive the trim strip and separate it from the other strips cut from said sheet.
Claim 4
Dependent Claim
58 words
The apparatus defined in claim 1, wherein the means holding the strips on the first, second and third conveyor means, respectively, comprise a magnetized backing plate at the back surface of a moving element of each said conveyor means magnetically holding metal strips against the opposite surface of said moving elements as they pass over the backing plates.
Claim 5
Dependent Claim
50 words
The apparatus defined in claim 3, wherein each of said conveyor means includes a pair of rotatable nip rollers for engaging strips and moving them into contact with the moving element thereof of the respective conveyor means, and drive means connected to rotate at least one said pair of rollers.
Claim 6
Dependent Claim
97 words
The apparatus defined in claim 1, wherein the third conveyor means includes a downwardly sloped apron, a lateral chute disposed below the apron at its terminal end, the chute having a downwardly sloped guide surface, a concavely curved lateral guide element disposed opposite the terminal end of said apron and spaced outwardly therefrom such that the strips falling from the terminal end of said apron to the sloped guide surface are tumbled forwardly end-for-end to invert them, and said curved guide element limits forward tumbling movement of the strips as they are fed to the lateral chute.
Claim 7
Dependent Claim
86 words
The apparatus defined in claim 1, wherein the first conveyor means comprises a downwardly sloped apron extending from beneath the shear means, a hinged end segment on said apron, rotatable cam means supporting said hinged end segment, a pair of parallel side-by-side downwardly sloped lateral chutes disposed beneath the terminal end of said hinged segment of the apron, and means for rotating said cam means for moving said hinged segment of the apron between positions for distributing strips conveyed over the apron of said lateral chutes.
