March 6, 2014



By a News Reporter-Staff News Editor at Politics & Government Week -- A patent application by the inventors Liu, Heng (Guangzhou, CN); Tan, Dong (Guangzhou, CN); Wu, En (Guangzhou, CN); Ran, Fa (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: "As sheet-type mediums, such as paper money, paper, bill or the like, are commonly used in our everyday life, various mechanical apparatus for sheet-type mediums are becoming available, such as a separating apparatus, a detecting apparatus, a bundling apparatus or the like. In the sheet-type medium bundling device, the sheet-type mediums need to suffer four successive processes, i.e., a stacking operation, an arranging operation, a bundling operation and a conveying operation. Therefore, the traditional sheet-type medium bundling device includes a conveying passage, an arranging mechanism, a clamping and conveying mechanism and a bundling mechanism. The clamping and conveying mechanism normally employ a mechanical pushing member. In operation, every single sheet of sheet-type medium is conveyed to a stacking plate at the arranging mechanism via the conveying passage. After a time period of T1, a stack of sheet-type mediums is formed. The arranging mechanism performs a long side arranging and a short side arranging to the stack of sheet-type mediums so as to form a sheet-type medium stack within a time period of T2. Then the clamping and conveying mechanism clamps and conveys the arranged sheet-type medium stack to the bundling mechanism, and it takes a time period of T3 for the bundling mechanism to perform the bundling operation. Next, it takes the clamping and conveying mechanism a time period of T4 to convey the bundled sheet-type medium stack out. That is, an operation cycle of a traditional sheet-type medium bundling device is a total time period of Tt (cycle time)=T1 (stacking time)+T2 (arranging time)+T3 (bundling time)+T4 (outputting time). Therefore this kind of sheet-type medium bundling device is time-consuming and thus has a low efficiency.

"In order to reduce the stacking time T1, those skilled in the art usually provide an additional stacking plate to realize a parallel operation solution by utilizing two stacking plates alternately for the stacking and the bundling. However, in this type of sheet-type medium bundling device, a mechanical pushing member is required for switching the stacking plates between two positions successively and repeatedly. Further, since the distance between the two positions is large, this type of sheet-type medium bundling device system is complicated and occupies too much space.

"Therefore, there is an urgent demand to provides a sheet-type medium bundling device which can solve the above problems while being less time consuming, high in efficiency and space saving."

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 this, an object of the present application is to provide a sheet-type medium bundling device which is less time consuming, high in efficiency and space saving.

"In order to achieve the above object, it is provided according to the present application a sheet-type medium bundling device for a cooperative operation of stacking and bundling of sheet-type mediums. The sheet-type medium bundling device includes: a conveying passage, a bundling mechanism, a position switching mechanism, a stacking position formed at an end of the conveying passage, and a bundling position formed corresponding to the bundling mechanism. Wherein the conveying passage, the bundling mechanism and the position switching mechanism are mounted on a frame. The position switching mechanism includes a power shaft driven by a motor and at least two stacking plates evenly provided on the power shaft, and when one of the stacking plates is located at the stacking position, another one of the stacking plates is located at the bundling position.

"Preferably, the power shaft is provided with a mounting shaft sleeve, on which the stacking plates are fixedly mounted. Each stacking plate is of a 'U' shape or a 'V' shape and is opened outwards. Each stacking plate includes a guiding surface located upstream of the power shaft and a stacking surface located downstream of the power shaft. An end of the guiding surface is bent towards an upstream direction of the power shaft, such that a guiding surface at the stacking position is contiguous with the end of the conveying passage, thereby guiding every single sheet of sheet-type medium out of the conveying passage to stack the sheet-type mediums on the stacking surface at the stacking position. The guiding surface, on one hand, is configured for guiding the sheet-type medium conveyed from the conveying passage, and on the other hand, is configured for blocking the sheet-type medium on the stacking surface, to prevent the sheet-type medium on the stacking surface from leaving the stacking surface in a position switching operation.

"Preferably, a code disc is mounted at an end of the power shaft, and the code disc is provided thereon with notches corresponding to the stacking plates. A sensor for sensing the information of the notches is mounted at a position corresponding to the code disc. By means of the code disc and the sensor, a specific location of each stacking plate on the position switching mechanism can be monitored in real time, thereby ensuring the accuracy of position switching of the position switching mechanism.

"Preferably, the number of the stacking plates is six, and the stacking position and the bundling position correspond to two adjacent stacking plates. Since the six stacking plates are evenly provided on the power shaft, and the stacking position and the bundling position correspond to two adjacent stacking plates, the angle between the stacking position and the bundling position is 60.degree., thereby the structure is compact, which effectively saves the space occupied by the sheet-type medium bundling device.

"A falling position is formed downstream of the bundling position, and a falling plate is obliquely mounted at a position corresponding to the falling position. Because of the inclined arrangement of the falling plate, the sheet-type medium stack on the stacking plate moved to the stacking position is blocked by the falling plate and slides freely along the falling plate, thereby completing the falling operation of the present application.

"Preferably, each stacking plate is provided with a groove, and one end of the falling plate extends towards a direction of the groove to form a blocking arm which blocks the sheet-type medium stack on the stacking plate, such that the sheet-type medium stack falls onto the falling plate, and the other end of the falling plate corresponds to a position of a container for storing a sheet-type medium stack to guide the sheet-type medium stack to fall into the container. When a stacking plate passes the falling position, the blocking arm of the falling plate passes through the groove in the stacking plate to block the sheet-type medium stack on the stacking plate such that the sheet-type medium stack slides automatically along the falling plate to the container to be stored therein. Therefore, it substantially takes no time for the falling operation of the present application, and the sheet-type medium bundling device according to the present application has a compact structure and occupies a small space.

"A long side arranging mechanism is mounted at a position corresponding to the stacking position, and a short side arranging mechanism is mounted at a position corresponding to the bundling position. The long side arranging mechanism and the short side arranging mechanism are configured for arranging the sides of the sheet-type mediums, to facilitate the clamping and conveying and the bundling of the sheet-type mediums. Therefore the sheet-type medium bundling device according to the present application has a compact structure and occupies a small space.

"A clamping and conveying mechanism is mounted at a position corresponding to the bundling position, and the clamping and conveying mechanism clamps and conveys the sheet-type medium stack at the bundling position to the bundling mechanism.

"Preferably, the clamping and conveying mechanism includes a motor, a synchronous belt, a slide shaft and a clamp assembly. Wherein, the slide shaft is parallel to a stacking plate at the stacking position, and one end of the slide shall is mounted on a mounting frame at a left side of the position switching mechanism, the other end of the slide shaft is mounted on a fixing frame at a right side of the position switching mechanism. The clamp assembly is slidably mounted on the slide shaft. The motor is connected to the synchronous belt to drive the synchronous belt to move. The synchronous belt is connected to the clamp assembly to drive the clamp assembly to slide along the slide shaft. And the clamp assembly is configured to clamp the sheet-type medium stack at the bundling position and convey the sheet-type medium stack to the bundling mechanism.

"Particularly, a sensor is mounted on the mounting frame for detecting an initial position of the clamp assembly. The sensor facilitates the control of the sheet-type medium bundling device according to the present application.

"Particularly, the clamp assembly includes: a sliding block slidably mounted on the slide shaft and fixedly connected to the synchronous belt; a clamping frame fixedly connected to the sliding block; an upper clamping plate and a lower clamping plate, each of which being elastically connected to the clamping frame and can rotate about a rotary shaft; and a guiding plate, one end of the guiding plate being fixedly mounted on the mounting frame, and the other end of the guiding plate being formed with a guiding head having a guiding inclined surface. Two limiting sliding blocks are correspondingly mounted on the opposite surfaces of the upper clamping plate and the lower clamping plate. The guiding plate guides, via the guiding head, the upper clamping plate and the lower clamping plate to open and is supported in an angle formed by the two limiting sliding blocks. During the clamping and conveying of the sheet-type medium stack, the synchronous belt drives the upper clamping plate and the lower clamping plate to move towards the bundling position through the sliding blocks. After a certain distance, the two limiting sliding blocks are disengaged from the guiding plate, such that the upper clamping plate and the lower clamping are rotated towards each other under the elastic forces, thereby clamping the sheet-type medium stack. When releasing the sheet-type medium stack, the synchronous belt drives the upper clamping plate and the lower clamping plate to move towards the mounting frame along the slide shaft, such that the two limiting sliding blocks slide along the guiding inclined surface of the guiding head, thereby the upper clamping plate and the lower clamping plate are gradually opened.

"Further, each stacking plate is provided with a groove, and the ends of the upper clamping plate and the lower clamping plate are bent towards directions of the grooves to form an upper clamping block and a lower clamping block opposite to each other. The groove is configured for providing a space for the clamp assembly to clamp or release the sheet-type mediums.

"Further, a supporting plate is provided perpendicularly between the upper clamping plate and the lower clamping plate, and the supporting plate can rotate about a rotary shaft and is elastically mounted on the upper clamping pate. A blocking plate is mounted at a position corresponding to the supporting plate, and the blocking plate can rotate about a rotary shaft and is elastically connected to the frame. When the clamp assembly is moved along the slide shaft, the supporting plate collides with the blocking plate until the supporting plate is rotated and is disengaged from the lower clamping plate. After the limiting sliding blocks on the upper clamping plate and the lower clamping plate are disengaged from the guiding plate, the upper clamping plate and the lower clamping plate are maintained in an open state by the supporting assembly. When the upper clamping plate and the lower clamping plate are moved to a position to performing the clamping operation, the supporting plate collides with the blocking plate, and is rotated and thus disengaged from the lower clamp plate under the blocking of the blocking plate. At this time, the upper clamping plate and the lower clamping plate lose the supporting of the supporting plate, thereby clamping the sheet-type medium stack instantly, to prevent the sheet-type mediums from being deformed by the upper clamping plate and the lower clamping plate.

"Further, the two limiting sliding blocks form a guiding angle cooperating with the guiding head. The guiding angle is designed to facilitate the opening of the upper clamping plate and the lower clamping plate when the clamp assembly is restored to its original position (that is, being located at a left side of the bundling position).

"Compared with the prior art, the sheet-type medium bundling device of the present application achieves a cooperative operation of stacking and bundling of the sheet-type mediums by utilizing the position switching mechanism, and connects the stacking position with the bundling position through rotations of the stacking plates of the position switching mechanism, thereby finishing the switching between the stacking and the bundling operations of the sheet-type medium and achieving a parallel performing of the operations, which not only reduces the total time required for processing a stack of the sheet-type mediums and increase the operation efficiency, but greatly saved the space occupied by the present application. On one hand, the stacking plates are evenly provided on the power shaft, and after each position switching, two of the stacking plates are respectively located at the stacking position and the bundling position, such that the stacking and the bundling operations of the sheet-type mediums can be performed simultaneously, thereby effectively increasing the operation efficiency of the sheet-type medium bundling device. On the other hand, after completing the collection of the sheet-type mediums by the stacking plate at the stacking position, the stacking plate having completed the collection can be switched to the bundling position as long as the power shaft is rotated, thereby can achieve a repeated circulation of the stacking plate between the stacking position and the bundling position, which can solve the problem that the system is complicated and occupies too much space due to the long distance between the stacking position and the bundling position in the prior art, and can save the space.
