Abstract

Abstract A device for sorting disc-like objects, particularly coins, comprises a rotatable centrifugal plate onto which the objects to be separated or sorted are placed. One portion of the periphery of the plate defines a discharge for the separated coins which move below a stripper bar which is located to overlie a portion of the periphery of the plate and permit objects of a thickness below a maximum selected thickness to pass below the stripper and through the discharge. A guide track is arranged to extend substantially to the periphery of the plate at the discharge and a plurality of dropout openings for objects of various size are located at spaced locations along the length of the track. In addition, a relatively large size dropout opening and collecting chute is located a slight distance away from the periphery of the plate in a position to receive coins which are fed below the stripper in an overlapping condition. For this purpose, the track includes a guide bar which runs along one side of the track and against which the coins are directed and which includes a flat step wall portion of a thickness corresponding to the minimum thickness of an object to be sorted. The mechanism includes a first conveyor which overlies the plate at the discharge and engages and feeds coins into the discharge obliquely toward engagement against the running edge. When any coins are fed which are in an overlapping relationship with one on top of the other, the uppermost one is fed by the conveyor over the step wall and into the overlying coin receiving opening. The device includes a transfer conveyor for moving the coins delivered against the running edge in an initial movement along the trackway and a second conveyor which moves them completely along the trackway until they fall down an opening corresponding to the size thereof.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 240 words
A device for sorting disc-like objects, particularly coins, comprising a rotatable centrifugal plate onto which the objects to be sorted are placed, means defining a discharge passage adjacent a portion of said plate, a stripper located over said plate at the discharge passage and being spaced from said plate by an amount corresponding to the maximum thickness of the objects to be separated from the remainder of said objects, a guide track extending outwardly from the discharge passage and having a plurality of dropout openings for objects of varying size located at spaced locations along its length and including a first overlying coin receiving opening, said guide track having a guide bar portion on at least one side having a running edge extending to said plate with a flat step wall portion of a thickness above said tack which corresponds to the article having the smallest thickness which is being sorted, a first conveyor overlying said plate and extending over said step in said discharge and engageable with articles fed through said stripper into the discharge to urge them against said step and along said running edge, said first conveyor acting to move the top most of any overlapped objects over said step while the underlying object is retained against said step, and a second conveyor means overlying said track in a position to move the objects delivered to said track running edge along said track past said dropout openings.
Claim 2
Independent Claim 240 words
A device for sorting disc-like objects, particularly coins, comprising a rotatable centrifugal plate onto which the objects to be sorted are placed, means defining a discharge passage adjacent a portion of said plate, a stripper located over said plate at the discharge passage and being spaced from said plate by an amount corresponding to the maximum thickness of the objects to be separated from the remainder of said objects, a guide track extending outwardly from the discharge passage and having a plurality of dropout openings for objects of varying size located at spaced locations along its length and including a first overlying coin receiving opening, said guide track having a guide bar portion on at least one side having a running edge extending to said plate with a flat step wall portion of a thickness above said tack which corresponds to the article having the smallest thickness which is being sorted, a first conveyor overlying said plate and extending over said step in said discharge and engageable with articles fed through said stripper into the discharge to urge them against said step and along said running edge, said first conveyor acting to move the top most of any overlapped objects over said step while the underlying object is retained against said step, and a second conveyor means overlying said track in a position to move the objects delivered to said track running edge along said track past said dropout openings.
Claim 3
Dependent Claim 55 words
A device for sorting disc-like objects, according to claim 1, including at least one flat lever, means mountiNg said lever for rotation about a vertical axis adjacent said track, and spring means acting on said lever for engaging each object which is fed from said discharge and urging it in the direction of said step.
Claim 4
Dependent Claim 54 words
A device for sorting disc-like objects, according to claim 1, wherein said track includes a rail portion at one edge defining a running edge, said running edge having a flat step portion adjacent said plate and a remaining higher portion, and including a separating wedge formation between said higher portion and said step portion.
Claim 5
Dependent Claim 49 words
A device for sorting disc-like objects, according to claim 3, wherein said first conveyor includes an endless belt engageable with the objects over said plate at said discharge and for moving them into engagement with said running edge at the location of said step and directly before said wedge.
Claim 6
Dependent Claim 49 words
A device for sorting disc-like objects, according to claim 1, wherein said second conveyor means includes a second conveyor overlying said track and a transfer roller between said second conveyor and said first conveyor for engaging coins fed from said first conveyor and moving them to said second conveyor.
Claim 7
Dependent Claim 58 words
A device for sorting disc-like objects, according to claim 5, wherein said first conveyor comprises an endless conveyor belt, first and second guide rollers over which said conveyor belt is movable, said second guide roller being located adjacent said transfer roller and a drive roller for said transfer roller located between said transfer roller and said second roller.
Claim 8
Dependent Claim 41 words
A device for sorting disc-like objects, according to claim 6, including a hinge plate mounted over said track and being adjustable toward and away from aid track, stp means for positioning said hinge plate at a predetermined spacing from said track.
Claim 9
Dependent Claim 70 words
A device for sorting disc-like objects, according to claim 6, including a vertically movable swivel arm having a feed roller which bears on said transfer roller, spring means biasing said swivel arm to urge said feed roller to engage said transfer roller, said spring means including a two arm lever carrying said spring means and mounted on said swivel arm and having a free end bearing against a stationary stop.
