ABSTRACT:
A dual registering stacking interface stages, registers, transports, justifies and stacks forms in which forms are delivered to a side-by-side holding areas known as channels one and two, where they are held stationary and accumulate in a stack or continue feeding as separate forms. The improved access accumulator incorporates the physical separation of upper from lower transport belt assemblies. A separate upper transport assembly is installed using ball bearings as hinges on the existing upper output shaft spring loaded ball stud latches are used to latch upper assembly to lower assembly via two alignment blocks on either side of the device. Spring loaded latches provide the capability to pass multiple stacked pages into the device at one time thus allowing more than one page to pass into the stack together. The dual registering stacking interface and improved access accumulator use low friction roller guides with o-ring belt clearance and the dual registering stacking interface uses a novel side guide.
