Accumulation device for paper-like sheets

Abstract

An accumulation device for paper-like sheets comprises a conveying part, a clamping part, a guiding part and an accumulating part, which are connected serially. The conveying part is used for conveying the paper-like sheet to the clamping part. The clamping part comprises a drive shaft and multiple banknote-stacking wheels fixed to the drive shaft, and every banknote-stacking wheel is provided with multiple wheel blades having the same curvature. The paper-like sheet can be clamped between any two adjacent wheel blades and rotatably conveyed to the guiding part. The guiding part receives the paper-like sheet conveyed by the clamping part and guides the paper-like sheet to the accumulating part. The accumulating part is used for accumulating the paper-like sheet conveyed by the guide part. The paper-like sheets are reliably collected among the wheel blades and prevented from scattering, and thus the paper-like sheets can be uniformly arranged in order and stacked on the accumulating part.

Description

[0001]The present application claims the benefit of priority to Chinese Patent Application No. 201210153172.3 titled “PAPER SHEET GATHERING DEVICE”, filed with the Chinese State Intellectual Property Office on May 17, 2012, the entire disclosure of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present application relates to a paper sheet gathering device, and particularly to a paper sheet gathering device that conveys paper money, checks, paper representing value and the like with vanes of stacking wheels.BACKGROUND OF THE INVENTION[0003]The paper sheet gathering device refers to a device that conveys paper sheets (such as paper money, checks and paper representing value) at a predetermined number (for example, 100) and gathers the same at a gathering component. In the paper sheet gathering device, paper sheets conveyed continuously are received between two adjacent vanes of the stacking wheel and thus are rotationally conveyed, such that the paper sheets...

AI Technical Summary

Benefits of technology

The present patent aims to provide a device for gathering paper sheets that can reliably receive paper sheets between wheel vanes and avoid the straggle of the sheets. This device includes a third stacking wheel with a different radian between the first and second stacking wheels, which helps to securely hold the paper sheet in place and align it with the others. Additionally, the surface of the paper sheet is formed with concave-convex folds that increase friction with the wheel vanes, preventing the sheet from moving away from them. This results in a more uniform alignment and stacking of the paper sheets, while avoiding straggle.

Problems solved by technology

In the existing paper sheet gathering device, since the interval between adjacent vanes of the stacking wheel is large, no sufficient clamping force is applied to the paper sheets such that they are rotationally conveyed, the head portions of the paper sheets are away from the root portions of the vanes of the stacking wheel increasingly under the action of the centrifugal force, thereby the paper sheets are moved out of the range between the two vanes of the stacking wheel, resulting in the straggle and irregular stacking of the paper sheets.
