For those skilled in the art to better understand technical solutions of the present application, the present application is described in detail in conjunction with drawings and embodiments hereinafter.
A recycling cash box mechanism of a banknote processing device is provided according to embodiments of the present application, and can be applied in banknote processing devices such as an automatic cash dispenser and an automatic teller machine. The structure of the recycling cash box mechanism according to the embodiments of the present application is described in detail by taking the recycling cash box mechanism used in the automatic teller machine as an example.

The main body controller 7 is configured to control the automatic teller machine on the whole, and to accurately control the operation states of each part in the automatic teller machine mainly by processing signals sent from sensors. The entire banknote processing unit 6 can be seen when the front door 8 is opened, and a deposit cash box mechanism and a recycling cash box mechanism can be seen when the vault door 9 is opened.
As shown in FIG. 2, the banknote processing unit 6 mainly includes a banknote inlet/outlet 11, a banknote separating wheel 12, a reversing block 13, a connecting passage 14, a vault, and a deposit conveying passage 15, a recycling conveying passage 16, a recycling conveying passage 17, a recycling conveying passage 18, a recycling cash box mechanism 19, a deposit cash box mechanism 20, a banknote temporary storage unit 21 and a banknote identification unit 22. The banknotes move in the banknote processing unit 6 through multiple banknote conveying passages, and the reversing block 13 is used to switch different banknote conveying passages to allow the banknotes to be conveyed along a target path, and is generally driven by an electromagnetic mechanism. The vault is used for placing each recycling cash box mechanism 19 and the deposit cash box mechanism 20, and the banknote conveying passages above the vault are connected to the banknote conveying passages inside the vault via the connecting passage 14. A groove is provided on the vault to accommodate the connecting passage 14, and the length of the groove is configured to allow the banknotes to pass through, and the width of the groove is the width of the driving wheel in the connecting passage 14. The driving wheels are used for clamping banknotes delivered from the upward side of the connecting passage 14, and the power source of the driving wheels may adopt an independent driving source and may also be introduced from other part of the banknote processing device via a gear transmission mechanism. The deposit cash box mechanism 20 is mainly used for storing banknotes deposited by the customers, and the recycling cash box mechanism 19 can not only store banknotes deposited by the customers but also provide banknotes for the customers performing a withdrawing operation. The number of the deposit cash box mechanism 20 and the number of the recycling cash box mechanism 19 can be flexibly set according to specific application occasions.
The customer firstly puts the banknotes into the banknote inlet/outlet 11 when depositing banknotes, the banknotes inside the banknote inlet/outlet 11 are separated into single sheet of banknote by the banknote separating wheel 12, to be easy to convey. Under the action of the reversing block 13, the banknotes are conveyed from the banknote conveying passage indicated by an arrow a into the banknote identification unit 22, the banknotes identified to be qualified are sent into the banknote temporary storage unit 21 while the banknotes identified to be unqualified are sent back to the banknote inlet/outlet 11 via the banknote conveying passage indicated by an arrow b and then are returned to the customer. After all the banknotes are identified, the qualified banknotes in the banknote temporary storage unit 21 pass through the banknote identification unit 22 and pass through the connecting passage 14 through the banknote conveying passage indicated by an arrow c, and finally enter into the deposit cash box mechanism 20 via the banknote conveying passage 15 or enter into the corresponding recycling cash box mechanism 19 via one of the recycling conveying passage 16, the recycling conveying passage 17 and the recycling conveying passage 18. When the customer needs to withdraw money, the banknotes in the recycling cash box mechanism 19 are delivered into the banknote identification unit 22 through the corresponding recycling conveying passage 16, 17 or 18, and further delivered into the banknote inlet/outlet 11, and finally are taken out by the customer.
As shown in FIGS. 3 to 7, the recycling cash box mechanism according to an embodiment of the present application includes a box cover 26, a box body 29, a padlock 30, a handle, a banknote pressing plate 31, a banknote dispensing/receiving port 41, a pulley 42, a transmission mechanism and a banknote dispensing conveying passage 47. The transmission mechanism can be connected to the box body 29 and includes a banknote receiving vane wheel 43 and a banknote dispensing roller wheel 46. The box cover 26 and the box body 29 form a space for accommodating banknotes, a banknote stacking plate is provided at the bottom of the box body 29, and generally, the banknote stacking plate is a base plate of the box body 29. The box body 29 is the installation base for most parts of the recycling cash box mechanism, and the padlock 30, the banknote pressing plate 31, the banknote dispensing/receiving port 41, the pulley 42, the banknote receiving vane wheel 43, the banknote dispensing roller wheel 46 and the banknote dispensing conveying passage 47 can all be arranged on the box body 29. The padlock 30 is used for positioning the box body 29 with respect to the vault. An operator can disassemble the recycling cash box mechanism via the handle, to realize the banknote replenishment and recycle or the maintenance of the recycling cash box mechanism and etc. The banknote pressing plate 31 is slidable with respect to the box body 29 and is connected to the box body 29 via a reset member, such as a spring, to allow the banknote pressing plate 31 to automatically reset in the banknote dispensing process. The pulley 42 may guide the banknotes entering from the banknote dispensing/receiving port 41 into a deposit conveying passage, the deposit conveying passage is arranged to butt the banknote receiving vane wheel 43, that is, the banknote receiving vane wheel 43 is located at the banknote dispensing/receiving port 41 of the recycling cash box mechanism. The banknote dispensing roller wheel 46 is opposite to the banknote stacking plate, that is, the banknotes on the banknote stacking plate may move toward the banknote dispensing conveying passage 47 through the banknote dispensing roller wheel 46, and the banknote dispensing roller wheel 46 can be located at a lateral side of the banknote receiving vane wheel 43 to form a banknote blocking mechanism. For avoiding the banknotes being stopped after collide with the banknote dispensing roller wheel 46, the banknote dispensing roller wheel 46 may slowly rotate at a certain speed, to bring the banknotes onto the banknote stacking plate.
When the customer deposits money, the qualified banknotes in the banknote temporary storage unit enter from the banknote dispensing/receiving port 41 of the recycling cash box mechanism, and the banknotes move along the deposit conveying passage under the action of the pulley 42 and are conveyed by the rotating banknote receiving vane wheel 43, and when rotating with the banknote receiving vane wheel 43, the banknotes will be blocked by the banknote blocking mechanism formed by the banknote dispensing roller wheel 46. At this time, the rotating vanes of the banknote receiving vane wheel 43 apply a thrust force on the banknotes to make the banknotes fall on the banknote stacking plate in the box body 29 and being stacked in the box body 29, and the banknotes further apply an action force on the banknote pressing plate 31, to make the banknote pressing plate 31 to slide with respect to the banknote stacking plate, and the spring between the banknote pressing plate 31 and the box body 29 is then stretched. When the customer withdraws money, the banknote receiving vane wheel 43 stops rotating, the spring between the banknote pressing plate 31 and the box body 29 recovers to the original state, to make the banknotes inside the box body 29 to keep moving toward the banknote dispensing roller wheel 46 along the banknote stacking plate, and the banknote dispensing roller wheel 46 may keep rotating to separate the whole stack of banknotes into single sheet of banknote, to facilitate the banknote entering into the banknote dispensing conveying passage 47 and further being conveyed to the banknote dispensing/receiving port 41.
According to the above description, the recycling cash box mechanism according to the embodiments of the present application adopts a combination of the banknote receiving vane wheel 43 and the banknote dispensing roller wheel 46 to stack and dispense the banknotes, thus the thickness variation of the banknotes will not affect the operation of the recycling cash box mechanism. Compared with the content introduced in the background art, the above mechanism does not need to adjust the fit clearances between parts of the mechanism according to the thickness variation of different banknotes in working, thereby greatly simplifying the operation of the recycling cash box mechanism.
As shown in FIGS. 5 to 8, in a further technical solution, the banknote dispensing roller wheel 46 includes a first roller wheel 461 and a second roller wheel 462 rotatably cooperating with the first roller wheel 461. A rotation shaft 463 of the first roller wheel 461 is fixedly connected to a rotation shaft 464 of the second roller wheel 462, and the rotation shaft 464 of the second roller wheel 462 is rotatable around its own axis. Generally, the rotation shaft 464 of the second roller wheel 462 may be positioned on the box body 29. In the banknote depositing process, the banknote dispensing roller wheel 46 needs to be located at the lateral side of the banknote receiving vane wheel 43 to form the banknote blocking mechanism, that is, the first roller wheel 461 is located at the lateral side of the banknote receiving vane wheel 43 and the whole banknote dispensing roller wheel 46 is located in the rotation range of the banknote receiving vane wheel 43. In the banknote dispensing stage, the rotation shaft 464 of the second roller wheel 462 rotates around its own axis under the action of the driving mechanism, and the rotation shaft 463 of the first roller wheel 461 is fixedly connected to the rotation shaft 464 of the second roller wheel 462, to make the first roller wheel 461 rotate with respect to the second roller wheel 462, and at this moment, the whole banknote dispensing roller wheel 46 interacts with the stacked banknotes with a large area, to better separate and convey the banknotes. The roller wheel driving mechanism used for realizing the rotation of the rotation shaft 464 of the second roller wheel 462 may adopt a servo motor which can be used to control the working state of the banknote dispensing roller wheel 46 according to the working state of the recycling cash box mechanism. Besides, the rotation shaft 463 of the first roller wheel 461 and the rotation shaft 464 of the second roller wheel 462 may be fixedly connected by a connecting rod, and a connecting plate 465 is adopted in the present application preferably to fixedly connect the rotation shafts 463 and 464, and the connecting plate 465 may be embodied as a metal plate.
Compared to of the solution using a single roller wheel to implement the banknote blocking and separating function, the action area between the banknotes and the above banknote dispensing roller wheel 46 formed by the first roller wheel 461 and the second roller wheel 462 is greatly increased, and apparently, the banknote dispensing roller wheel 46 may effectively optimize the operational reliability of the whole recycling cash box mechanism.
Considering that two ends of the banknote are usually extended out of the vanes of the banknote receiving vane wheel 43 when the banknote is in the banknote receiving vane wheel 43, two or more groups of the banknote dispensing roller wheels 46 are provided in the embodiment of the present application, to prevent the banknote dispensing roller wheels 46 from only acting on one end of the banknote that may cause the banknote unsteady condition. Further, two sides of the banknote receiving vane wheel 43 are respectively provided with one group of the banknote dispensing roller wheels 46, to ensure that two ends of the banknote are in contact with the banknote dispensing roller wheels 46, to realize the above object. Furthermore, during the banknote dispensing stage, the action area between the banknote dispensing roller wheels 46 and the banknotes further increases as the number of groups of the banknote dispensing roller wheels 46 increases, therefore the banknote separating intensity is better.
However, in the case that two or more groups of the banknote dispensing roller wheels 46 are working, if the banknote contact points of the two groups of the banknote dispensing roller wheels 46 respectively at two sides of the banknote receiving vane wheel 43 are arranged in a certain time sequence or are distributed in disorder, a part of the banknotes are not in contact with the two groups of the banknote dispensing roller wheels 46 simultaneously, which may result in a slight swing of the banknotes, thus the movement of the banknotes is still unsteady. For solving this problem, in the recycling cash box mechanism of the present application, a connecting line between the banknote contacting points of the banknote dispensing roller wheels 46 respectively at two sides of the banknote receiving vane wheel 43 is in parallel with the axis of the banknote receiving vane wheel 43. It can be understood that, when the banknotes move into the banknote receiving vane wheel 43, the extending direction of the bottom of the banknotes is approximately in parallel with the axis of the banknote receiving vane wheel 43, therefore the above arranging manner can greatly increase the probability of the banknotes simultaneously contacting with the two groups of the banknote dispensing roller wheels 46 respectively at two sides of the banknote receiving vane wheel 43.
In a further technical solution, the roller wheel driving mechanism connected to the banknote dispensing roller wheels 46 includes a rotational member 49 fixed to the rotation shaft 464 of the second roller wheel 462, an electromagnetism component 45 cooperating with the rotational member 49 to apply a rotation driving force, and a reset member 51 connected to the rotational member 49. The reset member 51 is generally embodied as a spring, and one end of the reset member 51 can be directly fixed to the box body 29. As shown in FIG. 5, when the recycling cash box mechanism is in a banknote depositing stage, the electromagnetism component 45 is deenergized, the reset member 51 applies a thrust force on the rotational member 49 to position the banknote dispensing roller wheels 46 at the lateral side of the banknote receiving vane wheel 43 to form the banknote blocking mechanism. When the recycling cash box mechanism is in a banknote dispensing stage, the electromagnetism component 45 is energized and applies a pulling force on the rotational member 49 to make the rotational member 49 rotate, and to further drive the rotation shaft 464 of the second roller wheel 462 to rotate, and finally make the first roller wheel 461 rotate to the upward side of the second roller wheel 462, thereby accomplishing the object of the whole banknote dispensing roller wheels 46 being in contact with the banknotes with a large area. In contrast, this driving mechanism has a simple structure. Certainly, the electromagnetism component 45 being energized may also position the banknote dispensing roller wheels 46 at the lateral side of the banknote receiving vane wheel 43, therefore, the specific arranging manner of the electromagnetism component 45 and the reset member 51 is not limited in the present application.
In practice, in the roller wheel driving mechanism, the rotational member 49 cooperates with the electromagnetism component 45 through a pushing lever 48 and may also be connected to the reset member 51 through a reset lever 50, that is, the electromagnetism component 45 applies an attraction force on the pushing lever 48 and the reset member 51 is directly connected to the reset lever 50. This arranging manner allows the rotational member to rotate more reliably and effectively.
For simplifying the internal structure of the box body 29, in an embodiment of the present application, the banknote receiving vane wheel 43 and the banknote dispensing roller wheels 46 are both arranged outside the box body 29; a gate 27 is rotatably provided at one end, opposite to the banknote receiving vane wheel 43 and the banknote dispensing roller wheels 46, of the box body 29, and a pushing shaft 28 is connected to the gate 27. When the gate 27 is closed, the banknotes are reliably placed inside the box body 29 due to the blocking of the gate 27. During the process of installing the recycling cash box mechanism into the vault, firstly the box body 29 is installed into the vault, and the gate 27 is opened when the pushing shaft 28 of the box body 29 comes into contact with a stopping block of the vault, and the transmission mechanism may be connected to the box body 29 at this moment. The gate 27 is opened, thus the internal space of the box body 29 is in communication with the space where the transmission mechanism is located, and the banknotes can be conveyed between the transmission mechanism and the box body 29.
Compared to the technical solution of arranging the whole transmission mechanism inside the box body 29, the above arranging manner apparently decreases the number of parts inside the box body 29, simplifies the structure of the box body, and makes it convenient to assemble and disassemble as well as to maintain later. Further, during the process of entering into the box body 29, the banknotes will not collide with the banknotes already stacked in the box body 29 and other parts in the box body 29 due to the simplified internal structure of the box body 29, therefore, the banknote deformation and jam phenomena will not occur.
In a preferred technical solution, the end of the box body 29 provided with the gate 27 is provided with a banknote blocking rod, the banknote blocking rod is located between the banknote dispensing roller wheel 46 and the banknote pressing plate 31. The arrangement of the banknote blocking rod makes the banknote subject to more restraint when being stacked inside the box body 29, to avoid the banknotes bursting out of the space between the banknote pressing plate 31 and the banknote receiving vane wheel 43 meanwhile avoid the banknotes applying a pressure on the banknote receiving vane wheel 43, to facilitate reducing the workload of the banknote receiving vane wheel 43. Furthermore, the banknote blocking rod includes a first banknote blocking rod 33 and a second banknote blocking rod 34, both of which are respectively located at two sides of the banknote pressing plate 31. Apparently, the first banknote blocking rod 33 and the second banknote blocking rod 34 acting on the banknotes at the same time can reliably restrain the banknotes, to make the banknotes be in a more stable condition.
A banknote conveyor belt 32 is arranged inside the box body 29 according to an embodiment of the present application, to make sure that the banknotes can be orderly stacked inside the box body 29. The banknote stacking plate is provided with a conveyor belt accommodating groove, and the upper surface of the banknote conveyor belt 32 is higher than the upper surface of the banknote stacking plate. When the banknotes rotate together with the banknote receiving vane wheel 43 and are blocked by the banknote dispensing roller wheel 46, the banknotes slip off onto the banknote stacking plate and come into contact with the banknote conveyor belt 32, and at this moment, the top of the banknotes has a trend of moving toward the banknote pressing plate 31 and the bottom of the banknotes also has a trend of moving toward the banknote pressing plate 31 due to the pulling force applied on the banknotes by the banknote conveyor belt 32. Therefore, under the action of the banknote conveyor belt 32, the banknotes can be stacked on the banknote pressing plate 31 in an approximately upright state.
To facilitate the power transmission of the recycling cash box mechanism, a first driving wheel 35, a first transmission wheel 36, a second transmission wheel 37, a third transmission wheel 38, a fourth transmission wheel 39 and a fifth transmission wheel 40 are arranged on the outer side of the box body 29. An external driving source drives the second driving wheel 44 which meshes with the first driving wheel 35, to drive the first driving wheel 35 to rotate, and the first driving wheel 35 drives the first transmission wheel 36, the second transmission wheel 37, the third transmission wheel 38, the fourth transmission wheel 39 and the fifth transmission wheel 40 to rotate via a belt, and finally drives the banknote conveyor belt 32 to operate. Preferably, the cross section of the banknote conveyor belt 32 is circular, which is better for driving the banknotes to move.
The pulley 42, the banknote receiving vane wheel 43 and the second driving wheel 44 in the above solutions may be driven by an electrical machine which is preferably embodied as a motor in the present application. Besides, the recycling cash box mechanism according to each embodiment of the present application can not only be arranged in a horizontal direction but also be arranged in a perpendicular direction, and the relative position of various parts may be appropriately adjusted in specific implementations, therefore, the recycling cash box mechanism arranged in any direction is deemed to fall into the scope of the present application.
