March 6, 2014



By a News Reporter-Staff News Editor at Politics & Government Week -- A patent application by the inventors Yin, Guangjun (Guangzhou, CN); Tan, Dong (Guangzhou, CN); Wu, En (Guangzhou, CN), filed on March 27, 2012, was made available online on February 20, 2014, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.

This patent application is assigned to GRG Banking Equipment Co., Ltd.

The following quote was obtained by the news editors from the background information supplied by the inventors: "Devices for processing sheet objects are widely used in our lives, e.g., an automatic teller machine, a moneychanger, a ticket vending machine. Objects processed by these processing devices are sheet objects such as banknotes or bills. The processing devices in operation need to convey the sheet objects in different directions in accordance with requirements of processing.

"Chinese Patent Application No. 200880101729.0 a three-way guider for redirecting sheet media, which can convey and guide sheet objects in three directions. The guider has three driving devices, i.e., one step motor and two lifting magnets. The guider controls to redirect two lateral passages as follows. The step motor drives a drive rod to rotate via two drive wheels. Pinions are provided at two ends of the drive rod, and racks are provided integrally on two guide plates of the guider. Thus, in rotation of the drive rod, the pinions engage with the racks, thereby driving the guide plates to move upwardly or downwardly. Blades of the guider are provided on the guide plates, and thus the upward or downward movement of the guide plates leads to the upward or downward movement of the blades of the guider, thereby realizing the redirection of the two lateral passages. As can be seen from the above operation, merely the redirection between the two lateral passages involves many transmission components. In this case, in order to ensure the normal upward or downward movement of the blades of the guider, the pinion and rack transmission is needed for both ends of the guider body. The many transmission components needed for the redirection between the two lateral passages of the guider causes a complex structure of the whole guider.

"In addition, the conveyance of the sheet objects in three directions for the above three-way guider needs the step motor and the two lifting magnets. Many power devices are involved in the whole guider and thus the production cost of the whole guider is increased."

In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "In view of the fact, there is provided a guider for conveying sheet objects according to embodiments of the present application, which has a simple structure and has a reduced cost of production.

"In order to achieve the object, the following technical solutions are provided according to an embodiment of the present application.

"A guider for conveying sheet materials, including: two side plates; two wheel assemblies disposed in parallel between the two side plates, a top passage plate being provided at tops of the two wheel assemblies; a rise-lower passage plate provided among the two wheel assemblies and the top passage plate, wherein a horizontal passage is formed between the rise-lower passage plate and the top passage plate, and lateral passages are formed between the rise-lower passage plate and the wheel assembly as well as between the rise-lower passage plate and the wheel assembly, and wherein the rise-lower passage plate is arranged hoistably and lowerably in the two side plates; a first driving device adapted to drive the rise-lower passage plate to move upwardly or downwardly; a redirecting member hinged between the two lateral passages and configured to perform a switch between the two lateral passages; and a second driving device adapted to drive the redirecting member to rotate.

"Preferably, the first driving device includes: a motor; a cam connected with an output shaft of the motor; a rotation shaft, which has two ends hinged to the two side plates respectively; two first connecting arms, each of which has two ends fixedly connected to the rotation shaft and the rise-lower passage plate respectively; and a second connecting arm fixedly connected to the rotation shaft and being in contact with a rim of the cam, wherein the rise-lower passage plate is located at an uppermost position if a lowermost position of the rim of the cam is in contact with the second connecting arm.

"Preferably, the guider for conveying sheet objects further includes: an extension spring, which has one end hitched to the second connecting arm and the other end hitched to the side plate adjacent to the second connecting arm.

"Preferably, in the guider for conveying sheet objects, the motor is fixed to the side plate adjacent to the second connecting arm by a motor fixing seat.

"Preferably, the guider for conveying sheet objects further includes: a controller, an upper sensor and a lower sensor, in which the upper sensor and the lower sensor are provided on the side plate adjacent to the second connecting arm, are arranged in an up-and-down form, and are adapted to detect a position of the second connecting arm, and the controller is adapted to receive a signal from the upper sensor and the lower sensor and to control the motor to start or stop in response to the signal.

"Preferably, in the guider for conveying sheet objects, the upper sensor and the lower sensor are each of a U-shaped structure, and the second connecting arm is located within the detection limits of the U-shaped structures.

"Preferably, in the guider for conveying sheet objects, grooves are provided in the side plates, and two ends of the rise-lower passage plate are slidable in the grooves.

"Preferably, in the guider for conveying sheet objects, two sides of the rise-lower passage plate are provided with a plurality of comb teeth.

"Preferably, in the guider for conveying sheet objects, the plurality of comb teeth is distributed uniformly on the two sides of the rise-lower passage plate.

"Preferably, in the guider for conveying sheet objects, the guider for conveying sheet objects is a guider for conveying banknotes.

"As can be known from the above technical solutions, in the guider for conveying sheet objects according to embodiments of the present application, the lateral passages are formed between the two wheel assemblies provided between the two side plates and the rise-lower passage plate respectively so as to convey the sheet objects in a vertical direction, and the horizontal passage is formed between the rise-lower passage plate and the top passage plate to convey the sheet objects in a horizontal direction. The rise-lower passage plate is provided hoistably and lowerably in the two side plates to implement upward and downward movement. If the first driving device drives the rise-lower passage plate to move upwardly to the uppermost position, the horizontal passage is closed and the lateral passages are open. In this case, with the redirecting member being hinged between the two lateral passages, the second driving device drives the redirecting member to rotate, so as to implement the switch between the two lateral passages. If the rise-lower passage plate moves downwardly to the lowermost position, the lateral passages are closed and the horizontal passage is open to convey the sheet objects in the horizontal direction. The present application can realize the functions of the existing guider. In the guider, the first driving device directly drives the rise-lower passage plate to move upwardly or downwardly so as to achieve the switch between the horizontal passage and the lateral passages, and the second driving device drives the redirecting member to rotate so as to achieve the switch between the two lateral passages.

"Compared with the guider in the prior art, in the guider for conveying sheet materials according to the present application, the switch between the two lateral passages may be implemented only by the second driving device rotating the redirecting member hinged between the two lateral passages. However, in the prior art, such a function may be implemented with the need of the step motor, the drive wheels, the drive rod, and the pinion and rack transmission mechanism. Compared with the prior art in which the switch between two lateral passages is implemented by a series of transmission components, the guider for conveying sheet objects according to embodiments of the present application has a simplified structure.

"In addition, in the guider for conveying sheet materials according to embodiments of the present application, the redirecting member for implementing the switch between the two lateral passages is driven by the second driving device to rotate, and the movement of the rise-lower passage plate is implemented by the first driving device. Thus, at most two power devices may be applied in the guider for conveying sheet objects according to embodiments of the present application. Compared with the guider in the prior art which adopts the step motor and the two lifting magnets to implement the switch between passages, the power sources are reduced and the production cost of the guider is reduced according to embodiments of the present application.
