By a News Reporter-Staff News Editor at Information Technology Newsweekly -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventors Liu, Heng (Guangzhou, CN); Tan, Dong (Guangzhou, CN); Wu, En (Guangzhou, CN); Ran, Fa (Guangzhou, CN), filed on July 9, 2012, was made available online on July 3, 2014.

The assignee for this patent application is GRG Banking Equipment Co., Ltd.

Reporters obtained the following quote from the background information supplied by the inventors: "With the development and progress of science and technology, some companies that need to handle large amounts of cash mostly use a paper money processing machine to implement some actions, such as inspecting, one-hundred-separating and bundling, in which one important aspect is to stack multiple banknotes tidily. At present, a tidying mechanism of most paper money processing machines cannot be applicable to all the banknotes, this is because only one fixing baffle plate is provided in the length direction of the paper money in the tidying mechanism, which cannot meet the requirement for tidying multiple types of banknotes. As described in the Chinese Patent Application for utility model No. 200520023084.7, the tidying range in the length direction of the banknote is limited by the stroke of a push plate, while the tidying range in the short-side direction is limited by the movement range of an electromagnet, a lever or the like, thereby only tidying a single type of banknote. In order to meet the requirement for tidying banknotes with different lengths, it usually needs to mount limit devices at a banknote entrance (or a banknote separating inlet) when tidying multiple banknotes. When tidying multiple types of banknotes, these limit devices need to be adjusted manually, and generally to be operated only after the device is opened, so that the operation is not enough convenient. Furthermore, the mounting of the limit devices at the banknote entrance (or the banknote separating inlet) does not facilitate the optimization of the arrangement of components and wastes useful space in the machine body."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "Therefore, an object of the invention is to provide a sheet-like medium stack guiding device with a compact structure, which can meet stacking requirements of sheet-like media with different lengths. Based on this, the invention also provides a system and method for controlling the sheet-like medium stack guiding device, which may automatically tidy sheet-like media with different lengths to improve work efficiency greatly.

"To solve the above technical problems, the invention provides a sheet-like medium stack guiding device, including:

A medium stacking plate is mounted between the flapping tidying mechanism and the right limit plate, and is located outside a banknote stacking wheel.

"Preferably, the flapping tidying mechanism includes a front plate and a rear plate. The front plate is located at one side of the medium stacking plate, and is slidably connected to the rear plate. The rear plate is slidably connected to a rear plate guiding shaft and is adapted to make a reciprocating movement under driving of a rear plate vibration mechanism.

"Preferably, the device includes a front plate return spring, a front plate guiding shaft and a front plate guiding sleeve which form a front plate assembly along with the front plate, wherein the front plate guiding shaft is fixedly connected to the front plate after passing through the front plate guiding sleeve and the front plate return spring; the front plate guiding shaft is slidably connected to the rear plate through the front plate guiding sleeve; and the front plate spring is mounted between the front plate and the rear plate and is adapted to return the front plate.

"Preferably, the rear plate vibration mechanism includes a tidying motor and an eccentric wheel, wherein the eccentric wheel is mounted on an output shaft of the tidying motor and is in contact with a driving surface of the rear plate; two ends of the rear plate guiding shaft are fixedly connected to a tidying motor supporting plate, such that the rear plate slides along the rear plate guiding shaft in a left-right direction under the action of the eccentric wheel.

"Preferably, a rear plate return spring is provided, wherein one end of the rear plate return spring is connected to the tidying motor supporting plate and the other end of the rear plate return spring is connected to the rear plate, such that the working surface of the eccentric wheel is always in contact with the driving surface of the rear plate.

"Preferably, a plurality of bearings are mounted on the tidying motor supporting plate such that the motor supporting plate slides along a sliding support plate in the left-right direction as the left limit plate moves. The sliding support plate and a connection plate of the sliding support plate are fixed to the left passage plate.

"Preferably, a flapping tidying mechanism sensor and a flapping tidying mechanism sensor detecting piece are provided to detect a position of the rear plate.

"Based on this, the control system for the sheet-like medium stack guiding device includes a controller including:

"an image acquisition module configured to acquire image information of a medium;

"a data processing module configured to judge a type of the medium according to pre-stored medium type image information, to search for a length of the medium according to the type of the medium, to calculate a distance to be adjusted according to the length of the medium, and to convert the distance to be adjusted into an amount of movement of an execution element;

"Accordingly, the control method for the sheet-like medium stack guiding device specifically includes:

"acquiring image information of the medium;

"judging the type of the medium according to pre-stored medium type image information;
