Abstract
Abstract In order to prevent oscillatory motion from being imparted to a stack of bills or the like as they are successively separated into another stack by a plurality of suction heads rotatably mounted on a rotary disk in an annular arrangement, each of the suction heads is provided with an arcuate surface through which are formed ports for applying suction to the successive bills. The arcuate surface is such that the distance between the surface and the axis of rotation of the suction head gradually increases from one edge of the arcuate surface, where the suction head first contacts each foremost one of the bills, to the opposite edge thereof. Each suction head may have another arcuate surface adapted to minimize the oscillatory motion imparted to the stack of already separated sheets.

Claim 1
Independent Claim
373 words
In a sheet counter of the type having a plurality of suction heads rotatably mounted on a rotary disk in an annular arrangement for successively separating each sheet from a sheet stack held by a sheet holding mechanism and forming a countcompleted sheet group, each of said suction heads being rotated on its own axis while revolving about the axis of said rotary disk and having at least one suction port adapted to successively suck up a sheet from said sheet stack; the improvement wherein each of said suction heads is generally triangularly shaped and includes as one of its sides an arched sheet suction surface through which said suction port is formed, said arched sheet suction surface acting to provide direct contact with each foremost one of the sheets held by the sheet holding mechanism, and further includes as another of its sides a convexly arched sheet contact surface provided with a gently arched surface having a large radius and adjacent to said sheet suction surface, said convexly arched sheet contact surface being adapted to cause transfer of the portion of said sheet contact surface positioned at the most outside part from the axis of said rotary disk along a substantially rectilinear locus by cooperation of rotation of the suction head on its own axis and revolution of the suction head around the axis of the rotary disk, the action of said convexly arched sheet contact surface imparting minimum oscillatory motion to the count-completed sheet group; whereby when a sheet is sucked and separated by the suction surface of one suction head which has reached the sheet stack, the bent state of the countcompleted sheets is retained by transference of the sheet contact surface of the suction head preceding said one suction head along said rectilinear locus and, during transference of said one suction head so as to bend a sheet separated from the sheet stack by said preceding suction head, said one suction head is made to transfer while adding said separated sheet to the count-completed sheet group and causing transference of the contact surface of said one suction head along the rectilinear locus on said added sheet, thereby to secure maintenance of the bent state of the countcompleted sheet group.
Claim 2
Dependent Claim
373 words
In a sheet counter of the type having a plurality of suction heads rotatably mounted on a rotary disk in an annular arrangement for successively separating each sheet from a sheet stack held by a sheet holding mechanism and forming a countcompleted sheet group, each of said suction heads being rotated on its own axis while revolving about the axis of said rotary disk and having at least one suction port adapted to successively suck up a sheet from said sheet stack; the improvement wherein each of said suction heads is generally triangularly shaped and includes as one of its sides an arched sheet suction surface through which said suction port is formed, said arched sheet suction surface acting to provide direct contact with each foremost one of the sheets held by the sheet holding mechanism, and further includes as another of its sides a convexly arched sheet contact surface provided with a gently arched surface having a large radius and adjacent to said sheet suction surface, said convexly arched sheet contact surface being adapted to cause transfer of the portion of said sheet contact surface positioned at the most outside part from the axis of said rotary disk along a substantially rectilinear locus by cooperation of rotation of the suction head on its own axis and revolution of the suction head around the axis of the rotary disk, the action of said convexly arched sheet contact surface imparting minimum oscillatory motion to the count-completed sheet group; whereby when a sheet is sucked and separated by the suction surface of one suction head which has reached the sheet stack, the bent state of the countcompleted sheets is retained by transference of the sheet contact surface of the suction head preceding said one suction head along said rectilinear locus and, during transference of said one suction head so as to bend a sheet separated from the sheet stack by said preceding suction head, said one suction head is made to transfer while adding said separated sheet to the count-completed sheet group and causing transference of the contact surface of said one suction head along the rectilinear locus on said added sheet, thereby to secure maintenance of the bent state of the countcompleted sheet group.
Claim 3
Dependent Claim
28 words
The improvement as defined in claim 1 wherein said sheet suction surface includes a recessed portion, said at least one suction port being formed through said recessed portion.
Claim 4
Dependent Claim
68 words
The shEet counter as claimed in claim 1, wherein said sheet suction surface is formed such that the distance between said sheet suction surface and the axis of rotation of said suction head increases gradually from the portion of said sheet suction surface provided with said suction port where said suction head contacts firstly with each foremost sheet held by the sheet holding mechanism to one edge thereof.
