In a sheet processing apparatus wherein sheets held in neat arrangement are successively fed into the apparatus for counting, identifying or like purposes, an infeed mechanism comprising: a first takeout roller rotatably supported adjacent one edge of the neat arrangement of sheets for frictional contact with each foremost sheet thereof; at least one second takeout roller rotatably supported adjacent the opposite edge of the neat arrangement of sheets in parallel spaced relationship to said first takeout roller and including a circumferential portion adapted for frictional contact with each foremost one of the sheets at prescribed time intervals, said second takeout roller being maintained in constant rotation during operation of the apparatus; and drive means operatively positioned for imparting the rotation of said second takeout roller to said first takeout roller at prescribed time intervals such that each foremost one of the sheets is thereby frictionally caused to shift relative to the rest of the sheets toward said second takeout roller before said circumferential portion of said second takeout roller moves into frictional contact with the foremost sheet, the rotation of said first takeout roller being suspended when the shifted foremost sheet is released therefrom, said drive means comprising a cam roller rotatably supported in coaxial relationship to said second takeout roller for simultaneous rotation therewith and having a circumferential portion of increased radius, and a transmission roller rotatably supported between said cam roller and said first takeout roller, whereby the rotation of said second takeout roller is frictionally conveyed to said first takeout roller only when said circumferential portion of said cam roller is in contact with said transmission roller, each foremost sheet initially shifted toward said second takeout roller by said first takeout roller being then fed into the apparatus by said circumferential portion of said second takeout roller.

In a sheet processing apparatus wherein sheets held in neat arrangement are successively fed into the apparatus for counting, identifying or like purposes, an infeed mechanism comprising: a first takeout roller rotatably supported adjacent one edge of the neat arrangement of sheets for frictional contact with each foremost sheet thereof; at least one second takeout roller rotatably supported adjacent the opposite edge of the neat arrangement of sheets in parallel spaced relationship to said first takeout roller and including a circumferential portion adapted for frictional contact with each foremost one of the sheets at prescribed time intervals, said second takeout roller being maintained in constant rotation during operation of the apparatus; and drive means operatively positioned for imparting the rotation of said second takeout roller to said first takeout roller at prescribed time intervals such that each foremost one of the sheets is thereby frictionally caused to shift relative to the rest of the sheets toward said second takeout roller before said circumferential portion of said second takeout roller moves into frictional contact with the foremost sheet, the rotation of said first takeout roller being suspended when the shifted foremost sheet is released therefrom, said drive means comprising a cam roller rotatably supported in coaxial relationship to said second takeout roller for simultaneous rotation therewith and having a circumferential portion of increased radius, and a transmission roller rotatably supported between said cam roller and said first takeout roller, whereby the rotation of said second takeout roller is frictionally conveyed to said first takeout roller only when said circumferential portion of said cam roller is in contact with said transmission roller, each foremost sheet initially shifted toward said second takeout roller by said first takeout roller being then fed into the apparatus by said circumferential portion of said second takeout roller.
Claim 3
Dependent Claim
41 words
The infeed mechanism as recited in claim 1, further including brake means for forcibly arresting the rotation of said first takeout roller at the moment when the transmission of rotation to said first takeout roller by said drive means is suspended.
Claim 4
Dependent Claim
112 words
The infeed mechanism as recited in claim 2, wherein said brake means comprises a braking roller rotatably supported in coaxial relationship to said second takeout roller for simultaneous rotation therewith, said braking roller having a circumferential portion of increased radius, an arm pivotally supported between said braking roller and said first takeout roller, a follower roller rotatably mounted on the free end of said arm and held in contact with said braking roller, and a brake element mounted intermediate between both ends of said arm, said brake element being urged into contact with said takeout roller only when said circumferential portion of said braking roller is in contact with said follower roller.
