Description:
[0001]    This application claims the priority of the Chinese Patent Application No. 201110288382.9, entitled “BANKNOTE INCLINATION CORRECTION DEVICE AND ATM”, filed with the Chinese Patent Office on Sep. 23, 2011, which is herein incorporated by reference in its entirety. 
       FIELD OF THE INVENTION 
       [0002]    The present invention relates to the technical field of paper correction, and in more to particular, to a correcting device for banknotes. The present invention also provides an automatic teller machine with the above correcting device for banknotes. 
       BACKGROUND OF THE INVENTION 
       [0003]    In a deposit process via an ATM (abbreviation for the Automatic Teller Machine), banknotes are put often on the skew into a deposit opening of the ATM by a user. Therefore, the banknotes need to be corrected by a correcting device before entering into the inside of the ATM. 
         [0004]      FIGS. 1 and 2  show an existing correcting device for banknotes with a cyclic correcting design. The process of correcting a skew banknote by the correcting device for banknotes is described as follows. After entering into the correcting device for banknotes, a banknote is transmitted to a correcting wheel  001  by a transmission wheel  007 , and in a banknote transmission passage  003  the banknote is subjected to a component force F′ a  parallel to the banknote transmission passage  003  and a component force F′ b , perpendicular to the banknote transmission passage  003  imparted from the correcting wheel  001 . Under the action of the component force F′ a , the banknote is transmitted forward in the banknote transmission passage  003 ; meanwhile, under the action of the component force F′ b , the banknote is aligned toward a reference wall  004 . Thus, the banknote is transmitted forward in the banknote transmission passage  003  while being aligned by taking the reference wall  004  as a reference. A sensor  005  is used for detecting the obliquity of the banknote. If the obliquity of the banknote does not meet a requirement, the banknote may enter again into the correcting device for banknotes under the guiding of a reversing block  006 . The above process is repeated until the obliquity of the banknote meets the requirement. Then, the reversing block  006  is activated to change the direction of the passage, so that the banknote is transmitted out of the correcting device. Thus, the correcting process is completed. 
         [0005]    The existing correcting device for banknotes adopts correcting wheels  001  singly arranged in three rows, and driven pressure wheels  002  corresponding to the correcting wheels  001 . Such a design aims to avoid the occurrence of banknote jam in the banknote transmission passage  003  as a forward corner of the banknote comes into contact with the reference wall  004  due to an excessive component force F′ b , or a long-time action of the correcting wheel  001 . However, this design has the following disadvantages. When a small-dimension banknote (i.e. a banknote with both a small length and a small width) is transmitted longitudinally, the banknote moves to the reference wall  004  by a relatively long distance due to the small width of the small-dimension banknote itself, and the correcting wheel  001  acts on the banknote for a shortened time because of the small length of the small-dimension banknote. For the above two reasons, the small-dimension banknote may not be able to move to the reference wall  004 . Although the cyclic correcting design used in the existing correcting device for banknotes can overcome this problem, the next banknote can enter into the correcting device only after a previous banknote has been corrected and left the correcting device based on the cyclic correcting design, resulting in the discontinuousness of banknote transmission. The discontinuousness of banknote transmission will affect the working efficiency of the ATM, and then a functional requirement of transmitting banknotes at a high velocity continuously cannot be satisfied. 
         [0006]    In sum, how to provide a correcting device for transmitting various-dimension banknotes at a high velocity continuously is a problem to be overcome presently by the skilled in the art. 
       SUMMARY OF THE INVENTION 
       [0007]    In view of this, the present invention provides a correcting device for banknotes which can transmit various-dimension banknotes at a high velocity continuously. 
         [0008]    In order to achieve the above object, the invention provides technical solutions as follows. 
         [0009]    A correcting device for banknotes includes: 
         [0010]    an inner passage plate and an outer passage plate, wherein a banknote transmission passage is formed between the inner passage plate and the outer passage plate; 
         [0011]    a reference wall disposed on one side of the inner passage plate and the outer passage plate; 
         [0012]    a transmission wheel located at the entrance of the banknote transmission passage and disposed on one of the inner passage plate and the outer passage plate; 
         [0013]    a plurality of correcting wheel sets disposed on one of the inner passage plate and the outer passage plate, wherein each of the plurality of correcting wheel sets includes at least one correcting wheel oriented toward the reference wall; and 
         [0014]    a transmission side wheel located between the reference wall and the plurality of correcting wheel sets, the transmission side wheel being parallel to the reference wall, wherein the rim linear velocity of the transmission side wheel is greater than the rim linear velocity of the at least one correcting wheel in each of the plurality of correcting wheel sets. 
         [0015]    Preferably, in the above correcting device for banknotes, both the inner passage plate and the outer passage plate are an arc with a radian less than 360° in shape. 
         [0016]    Preferably, the above correcting device for banknotes further includes a transmission floating pressure wheel mounted on the other one of the inner passage plate and the outer passage plate opposite to the transmission wheel, wherein the transmission floating pressure wheel is disposed such as to be in rolling contact with the transmission wheel. 
         [0017]    Preferably, the above correcting device for banknotes further includes a correcting floating pressure wheel mounted on the other one of the inner passage plate and the outer passage plate opposite to the at least one correcting wheel in each of the plurality of correcting wheel sets, wherein the correcting floating pressure wheel is disposed such as to be rolling contact with the at least one correcting wheel in each of the plurality of the correcting wheel sets. 
         [0018]    Preferably, the above correcting device for banknotes further includes the transmission floating pressure wheel, and the transmission side wheel is polygonal in shape. 
         [0019]    Preferably, the above correcting device for banknotes further includes the transmission floating pressure wheel. The correcting wheel sets are four in number, and are disposed successively from the entrance of the banknote transmission passage and then away from the entrance. 
         [0020]    Preferably, the above correcting device for banknotes further includes the transmission floating pressure wheel, and the correcting wheel set close to the transmission wheel includes two or more correcting wheels. 
         [0021]    Preferably, the above correcting device for banknotes further includes the transmission floating pressure wheel, and multiple transmission wheels are provided on a drive shaft perpendicular to a banknote transmission direction such as to be spaced equidistantly with each other along the drive shaft. 
         [0022]    Preferably, the above correcting device for banknotes further includes the transmission floating pressure wheel, and the transmission wheel is threaded such as to drive a banknote to move away from the reference wall. 
         [0023]    Based on the above correcting device for banknotes, the present invention further provides an automatic teller machine including the correcting device for banknotes described above. 
         [0024]    In the correcting device for banknotes according to the present invention, during the operation, the rim linear velocity of the transmission side wheel is greater than the rim linear velocity of the correcting wheel of the correcting wheel sets. Under the action of the transmission side wheel, the side of the banknote close to the transmission side wheel moves faster than the other side of the banknote close to the correcting wheel. The deflection of the banknote is achieved due to the velocity difference between the two sides of the banknote, so as to correct a banknote more efficiently and to more effectively prevent a forward corner, which is close to the correcting wheel, of the banknote from colliding with the reference wall to otherwise cause the banknote jamming or blocking phenomenon. Moreover, multiple correcting wheel sets are employed in the correcting device for banknotes, and each of the correcting wheel sets includes at least one correcting wheel. The multiple correcting wheels can increase the transverse component force of the correcting device perpendicular to the banknote transmission passages, so that a small-dimension banknote can reach the reference wall under the action of the transverse component force Accordingly, the correcting device for banknotes according to the present invention improves the correcting effect, thereby increasing the probability of correcting banknotes in one cycle, and the probability of correcting various-dimension banknotes. Therefore, the correcting device for banknotes according to the present invention can transmit various-dimension banknotes continuously at a high velocity.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0038]    An object of the present invention is to disclose a correcting device for banknotes for transmitting continuously various-dimension banknotes at a high velocity. Another object of the present invention is to disclose an automatic teller machine with the correcting device. 
         [0039]    The technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention as follows. It is apparent that the described embodiments are only a part of and not all the embodiments of the present invention. All the other embodiments occurred by the skilled in the art based on the embodiments in the present invention without any creative effort fall within the scope of protection of the present invention. 
         [0040]    Reference is made to  FIGS. 3 and 4 .  FIG. 3  is a front view of a correcting device for banknotes according to an embodiment of the present invention, and  FIG. 4  is a side view of the correcting device for banknotes according to an embodiment of the present invention. 
         [0041]    The embodiment of the present invention discloses a correcting device for banknotes including an inner passage plate  008 , an outer passage plate  009 , a reference wall  008   a , a transmission wheel  011 , a correcting wheel set  014  and a transmission side wheel  019 . 
         [0042]    A banknote transmission passage, in which a banknote is transmitted, is formed between the inner passage plate  008  and the outer passage plate  009 . 
         [0043]    The reference wall  008   a  is disposed on one side of the inner passage plate  008  and the outer passage plate  009 . The banknote is aligned by taking the reference wall  008   a  as a reference while it is conveyed forward in the banknote transmission passage. The correcting device for banknotes according to the embodiment of the present invention corrects a skew banknote depending on the reference wall  008   a  as a reference. Specifically, the alignment of a banknote is achieved by fining up one side edge of the banknote against the reference wan  008   a . Therefore, the banknote must be fully moved to the reference wall  008   a.    
         [0044]    The transmission wheel  011  is located at the entrance  1  of the banknote transmission passage, and is disposed on the inner passage plate  008  or the outer passage plate  009 . Multiple correcting wheel sets  014  are disposed on the inner passage plate  008  or the outer passage plate  009 . Each correcting wheel set includes at least one correcting wheel oriented toward the reference wall  008   a . The correcting wheels in respective correcting wheel sets  014  are mounted such as to be directed toward the reference wall  008   a  at the same installation angle θ. The installation angle θ is an angle between the plane on which the correcting wheel is located and the plane on which the reference wall  008   a  is located. In this way, the banknote is allowed to move toward the reference wall  008   a . The installation angle θ of the correcting wheel and the design rule of the correcting device are determined depending on the minimum-dimension banknote. 
         [0045]    The installation angle θ of the correcting wheel in the correcting wheel sets  014  can be calculated by the following formulas: 
         [0000]        V   a   =V *Sin θ  (1)
 
         [0000]        V   1   =V *Cos θ  (2)
 
         [0000]        S/V   1   =L/V   a   (3)
 
         [0000]        L=W   1   −W   2   (4)
 
         [0046]    It can be derived from formulas (1), (2), (3) and (4) that: θ=TAN −1 [(W 1 −W 2 )/S]. 
         [0047]    In these formulas, V a  is the component velocity of a banknote; V 1  is the transmission velocity of a banknote in the banknote transmission passage; V is the transmission velocity of a correcting wheel in a correcting wheel set  014 ; S is the length of a banknote in a banknote transmission direction from the transmission wheel  011  to the passage wheel  023  in the correcting device; L is the distance by which a banknote moves in the direction perpendicular to the banknote transmission passage in the correcting device; W 1  is the width dimension of the correcting device; and W 2  is the width of a minimum-dimension banknote. 
         [0048]    The installation angle θ of the correcting wheel must be determined such as to ensure that the minimum-dimension banknote (having a minimum width) moves to the reference side within a time T from the side of the correcting device opposite to the reference side. The time T is the time that a banknote passes through the correcting device at a component velocity V 1  in a direction perpendicular to the banknote transmission passage. 
         [0049]    The transmission side wheel  019  is located between the reference wall  008   a  and the correcting wheel sets  014 , and is installed at one end of a rotating shaft  017 . At the other end of the rotating shaft  017  a transmission pulley  018  is provided to supply with power to the rotating shaft  017 . The transmission side wheel  019  is parallel to the reference wall  008   a , and has a rim linear velocity greater than that of the correcting wheel of the correcting wheel sets  014 . In the case that banknote is wrinkled or turned up and thus cannot be transmitted forward, since the rim linear velocity of the transmission side wheel  019  is faster than that of the correcting wheel of the correcting wheel sets  014 , the transmission velocities on both sides of banknotes are not the same. That is, the transmission velocity of the side of the banknote at the transmission side wheel  019  is faster than that of the other side of the banknote at the correcting wheel sets  014 , so that the banknote may be deflected away from the reference wall  008   a . When the side edge of the banknote near the reference wall  008   a  is deflected to lean against the reference wall  008   a , and thus is blocked by the reference wall  008   a . At this time, even under the action of the transmission side wheel  019 , the banknote will not be deflected so as to achieve a correcting effect. 
         [0050]    In the correcting device for banknotes according to the present invention, during the operation, the rim linear velocity of the transmission side wheel is greater than the rim linear velocity of the correcting wheel of the correcting wheel sets. Under the action of the transmission side wheel, the side of the banknote close to the transmission side wheel moves faster than the other side of the banknote close to the correcting wheel. The deflection of the banknote is achieved due to the velocity difference between the two sides of the banknote, so as to correct a banknote more efficiently and to more effectively prevent a forward corner, which is close to the correcting wheel, of the banknote from colliding with the reference wall to otherwise cause the banknote jamming or blocking phenomenon. Moreover, multiple correcting wheel sets are employed in the correcting device for banknotes, and each of the correcting wheel sets includes at least one correcting wheel. The multiple correcting wheels can increase the transverse component force of the correcting device perpendicular to the banknote transmission passages, so that a small-dimension banknote can reach the reference wall under the action of the transverse component force. Accordingly, the correcting device for banknotes according to the present invention improves the correcting effect, thereby increasing the probability of correcting banknotes in one cycle, and the probability of correcting various-dimension banknotes. Therefore, the correcting device for banknotes according to the present invention can transmit various-dimension banknotes continuously at a high velocity. 
         [0051]    To further optimize the above technical effect, as shown in  FIG. 4 , both the inner passage plate  008  and the outer passage plate  009  are of an arc shape with a radian less than 360°. The existing correcting device for banknotes is of a closed circular shape, and operates in a cyclic correcting process in which, only after a previous banknote has been corrected and moved away from the correcting device, the next banknote can enter into the correcting device. In the correcting device according to the present invention, the various-dimension banknotes can be aligned to the reference wall  008   a  to achieve the correction in one cycle, without the need of adopting the banknote cyclic correcting process. Therefore, the device of the present invention is designed such as to be in an arc shape with a radian less than 360°. 
         [0052]    The correcting device for banknotes according to the invention further includes a transmission floating pressure wheel  013 . The transmission floating pressure wheel  013  is mounted on the inner passage plate  008  or the outer passage plate  009  opposite to the transmission wheel  011 , and is disposed in rolling contact with the transmission wheel  011 . The correcting device for banknotes further includes a correcting floating pressure wheel  020 . The correcting floating pressure wheel  020  is mounted on the inner passage plate  008  or the outer passage plate  009  opposite to the correcting wheel, and is disposed in rolling contact with the correcting wheel of the correcting wheel set  014 . If the transmission wheel  011  is installed on the inner passage plate  008 , there is a need for a certain space in the inside of the inner passage plate  008  to accommodate a power source and associated transmission structures; accordingly, a transmission floating pressure wheel  013  is installed on the outer passage plate  009  opposite to the inner passage plate  008 . In an alternative way, if the transmission wheel  011  is installed on the outer passage plate  009 , there is a need for a certain space in the inside of the outer passage plate  009  to accommodate a power source and associated transmission structures; accordingly, the transmission floating pressure wheel  013  is installed on the inner passage plate  008  opposite to the outer passage plate  009 . Under the tension action of the spring force, the transmission floating pressure wheel  013  always is in rolling contact with the transmission wheel  011 , and presses banknotes to transmit the banknotes. Similarly, the correcting floating pressure wheel  020  is installed and transmits banknotes in the same processes as that of the transmission floating pressure wheel  013 , which will not be repeatedly described herein. 
         [0053]    The transmission side wheel  019  of the correcting device for banknotes according to the invention is polygonal in shape. Referring to  FIGS. 5 to 7 ,  FIG. 5  is a sectional view taken along line A-A in  FIG. 3  according to an embodiment of the invention, showing a working state where the transmission side wheel presses a banknote so as to impart a force on the banknote;  FIG. 6  is a sectional view taken along line A-A in  FIG. 3  according to an embodiment of the invention, showing a working state where the transmission side wheel keeps away from a banknote so as to allow the banknote to be aligned against a reference wall successfully; and  FIG. 7  is an outline view of a transmission side wheel according to an embodiment of the present invention. 
         [0054]    Considering that the banknote must pass through the transmission side wheel  019  before moving to the reference wall  008   a , the transmission side wheel  019  in the present invention is designed to be polygonal in shape. Referring to  FIG. 5 , when the transmission side wheel  019  is in contact with the banknotes, the arc face  3  at the maximum diameter of the transmission side wheel  019  is lower than the arc face  4  of the inside passage of the outer passage plate  009 . The transmission side wheel  019  applies a resistance force to the banknote moving towards the reference wall  008   a  while pressing the banknote downwards, so that the banknote no longer moves towards the reference wall  008   a . Referring to  FIG. 6 , after the arc face  3  at the maximum diameter of the transmission side wheel  019  moves away from the banknote, there is a certain gap between a side  5  of the polygonal transmission side wheel  019  and the banknote, that is, the transmission side wheel  019  may not contact with the banknote. Thus, the transmission side wheel  019  no longer prevents the banknote from aligning to the reference wall  008   a . In this way, the transmission side wheel  019  can not only apply transmission force in transmission direction to the banknote, but also enable the banknote to move toward the reference wall  008   a . Referring to  FIG. 7 , the transmission side wheel  019  is pentagonal in shape, but the design of the transmission side wheel  019  is not limited to the pentagonal shape. The transmission side wheel  019  can be made of rubber materials to increase the friction force between the transmission side wheel  019  and the banknote, and to improve the efficiency of the device transmitting banknotes. 
         [0055]    Referring to  FIG. 3 , the correcting wheel sets  014  of the correcting device for banknotes according to the present invention are four in number, and are disposed successively from the entrance of the banknote transmission passage in a direction away from the entrance. The number of the correcting wheels in the correcting wheel set  014  close to the transmission wheel  011  is two or more. The correcting wheel sets  014  are located in middle of the banknote transmission passage, and are four in number, i.e. a first correcting wheel set  014   a , a second correcting wheel set  014   b , a third correcting wheel set  014   c  and a fourth correcting wheel set  014   d . The correcting wheel set close to the transmission wheel  011 , i.e. the first correcting wheel set  014   a , includes two or more correcting wheels. After the power is transmitted to the second correcting wheel set  014   b  through a pulley  015 , the second correcting wheel set  014   b  in turn transmits the power to the subsequent correcting wheel sets through a gear  016  so as to ensure that the correcting wheels rotate in the same direction at the same velocity. It should be noted that one correcting wheel may be included in the correcting wheel set close to the transmission wheel  011 . However, in the case that the correcting wheel set close to the transmission wheel  011  is configured with only one correcting wheel, the banknote may be deflected greatly about a holding point under the holding action of single correcting wheel so that the banknote can not be efficiently corrected. Therefore, two or more correcting wheels are preferably provided in the first correcting wheel set  014   a  close to the transmission wheel  011 . This configuration can ensure that multiple correcting wheels synchronously act on the banknote when the various-dimension banknote enters into the correcting wheel sets  014  to be hold, so as to prevent the excessive deflection of the banknote which would be caused by the single correcting wheel acting on the banknote, thereby enabling the banknote to be effectively corrected and then depart from the exit  2  of the correcting device. 
         [0056]    Under the action of the multiple correcting wheels, a force Fa perpendicular to the banknote transmission passage to which the banknotes are subjected increases, ensuring that minimum-dimension banknotes can be aligned with the reference wall  008   a  in the correcting device, so as to correct banknotes in one cycle. 
         [0057]    Reaming to  FIG. 3 , there are multiple transmission wheels  011  in the correcting device for banknotes according to the present invention. The multiple transmission wheels  011  are disposed on a drive shaft  010  perpendicular to the transmission direction of the banknotes and are arranged and spaced with equal distance along the drive shaft  010 . The transmission wheel  011  is provided with threads so as to drive the banknote to move away from the reference wall  008   a . A wheel outer circumferential surface of the transmission wheel  011  is configured with a spiral flange with a certain helix lead angle. According to the spiral configuration direction of the transmission wheel  011 , the banknote moves away from the reference wall  008   a . Therefore, the transmission wheel  011  has a role of appropriate adjustment to the skew extent of the banknote. This adjustment not only can prevent in advance the banknote from being turned up by the forward corner of the banknote early contacting with the reference wall  008   a , but also can facilitate subsequent movement of the banknote. 
         [0058]    Preferably, the reference wall  008   a  and the inner passage plate  008  are designed into one-piece structure, so as to eliminate the jamming of the banknote resulting from a joint gap between the reference wall  008   a  and the inner passage plate  008 . 
         [0059]    The present invention discloses an automatic teller machine including a correcting device for banknotes as described above. The automatic teller machine according to the invention also has the technical effects mentioned above by adopting the above correcting device for banknotes, which will not be described herein. 
         [0060]    In sum, the invention discloses a working process of a correcting device for banknotes. 
         [0061]    Referring to  FIGS. 4 and 8  to  11 ,  FIG. 8  shows configuration and features of a transmission wheel and a process of correcting a banknote state according to an embodiment of the present invention;  FIG. 9  shows a correcting process in the case where a banknote in a first state enters into the correcting device and a force analysis of the banknote during the correcting process according to an embodiment of the present invention;  FIG. 10  shows a correcting process in the case where a banknote in a second state enters into the correcting device and a force analysis of the banknote during the correcting process according to an embodiment of the present invention; and  FIG. 11  shows a correcting process in the case where a banknote in a third state enters into the correcting device and a force analysis of the banknote during the correcting process according to an embodiment of the present invention. 
         [0062]    Referring to  FIG. 4 , after passing through the separating roller  021 , the banknotes are continuously separated one after another, pass through the transmission device  022 , and are arranged on the banknote transmission passage with the same intervals so as to enter into the correcting device. After entering the correcting device, the banknotes is clamped by a row of transmission wheels  011  disposed on the banknote transmission path at the entrance of the correcting device and the transmission floating pressure wheels  013  disposed on the other side of the passage corresponding to the transmission wheel  011 . As shown in  FIG. 8 , the banknote moves away from the reference wall  008   a  under a force F1 of the transmission wheels  011  depending on the direction of configuration of the threads on the transmission wheels  011 . 
         [0063]    Referring to  FIGS. 9 ,  10  and  11 , a banknote in different form enters into the correcting wheel sets  014  of the correcting device. The following description is only made with reference to the limit positions illustrated in  FIG. 9 .  FIGS. 10 and 11  show the banknote states where the banknote may be corrected by the existing correcting device, which will not be discussed particularly. After a banknote in a banknote state c shown in  FIG. 9  enters into the correcting device, the spiral transmission wheel  011  at the entrance is unable to deflect a forward corner of the banknote away from the side wall. The banknote in a banknote state c shown in  FIG. 9  enters into the correcting wheel sets  014  of the correcting device, and under a clamping component Fa of the correcting wheel sets  014 , the banknote begins to be aligned with the reference. At this time, the banknote which has already been in contact with the reference wall is subjected to a resistance force f of the reference wall. The banknote continues to move toward the reference wall under a transverse component Fa of the correcting wheel  014 . If the process goes on, the forward corner of the banknote is wrinkled or turned up in the case of insufficient rigidity, causing banknote jamming or blocking. The transmission side wheel  019  designed to be polygonal will press downwardly the side of the banknote close to the reference wall, which can loose the forward corner of the banknote contacting with the reference wall, with the resistance force f disappearing. Because the transmission side wheel  019  applies a resistance force f′ to the banknote moving toward the reference wall  008   a  while pressing the banknote downwards, the banknote no longer moves toward the reference wall  008   a . At this time, since the rim linear velocity of the transmission side wheel  019  is greater than the rim linear velocity of the correcting wheel, that is, V2&gt;V1, the banknote can be deflected, so that the forward corner of the banknote will gradually move away from the reference wall  008   a . After the forward corner of the banknote moves away from the reference wall  008   a , the banknote is subject to the actions of the correcting wheel sets  014  and the transmission side wheel  019  at the same time. The rim linear velocity of the transmission side wheel  019  is greater than the rim linear velocity of the correcting wheel, resulting in the different transmission velocities at both sides of the banknote. In other words, the side of the banknote at the transmission side wheel  019  is transmitted at a greater velocity than the side of the banknote at the correcting wheel, that is, and thus the banknote may be deflected. The banknote leaves the correcting device after the side edge of the banknote is deflected to be aligned with the reference wall  008   a.
