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.
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.
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.
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.
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.
In view of this, the present invention provides a correcting device for banknotes which can transmit various-dimension banknotes at a high velocity continuously.
In order to achieve the above object, the invention provides technical solutions as follows.
A correcting device for banknotes includes:
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;
a reference wall disposed on one side of the inner passage plate and the outer passage plate;
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;
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
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.
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.
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.
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.
Preferably, the above correcting device for banknotes further includes the transmission floating pressure wheel, and the transmission side wheel is polygonal in shape.
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.
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.
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.
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.
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.
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.
In order to more clearly illustrate the embodiments of the invention or the technical solutions of the prior art, drawings needed to be used in the description of the embodiments or the prior art will be introduced briefly as follows.

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.
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.
Reference is made to
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 008a, a transmission wheel 011, a correcting wheel set 014 and a transmission side wheel 019.
A banknote transmission passage, in which a banknote is transmitted, is formed between the inner passage plate 008 and the outer passage plate 009.
The reference wall 008a 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 008a 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 008a as a reference. Specifically, the alignment of a banknote is achieved by fining up one side edge of the banknote against the reference wan 008a. Therefore, the banknote must be fully moved to the reference wall 008a.
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 008a. The correcting wheels in respective correcting wheel sets 014 are mounted such as to be directed toward the reference wall 008a 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 008a is located. In this way, the banknote is allowed to move toward the reference wall 008a. The installation angle θ of the correcting wheel and the design rule of the correcting device are determined depending on the minimum-dimension banknote.
The installation angle θ of the correcting wheel in the correcting wheel sets 014 can be calculated by the following formulas:
V
a
=V*Sin θ (1)
V
1
=V*Cos θ (2)
S/V
1
=L/V
a (3)
L=W
1
−W
2 (4)
It can be derived from formulas (1), (2), (3) and (4) that: θ=TAN−1[(W1−W2)/S].
In these formulas, Va is the component velocity of a banknote; V1 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; W1 is the width dimension of the correcting device; and W2 is the width of a minimum-dimension banknote.
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 V1 in a direction perpendicular to the banknote transmission passage.
The transmission side wheel 019 is located between the reference wall 008a 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 008a, 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 008a. When the side edge of the banknote near the reference wall 008a is deflected to lean against the reference wall 008a, and thus is blocked by the reference wall 008a. 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.
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.
To further optimize the above technical effect, as shown in
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.
The transmission side wheel 019 of the correcting device for banknotes according to the invention is polygonal in shape. Referring to
Considering that the banknote must pass through the transmission side wheel 019 before moving to the reference wall 008a, the transmission side wheel 019 in the present invention is designed to be polygonal in shape. Referring to
Referring to
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 008a in the correcting device, so as to correct banknotes in one cycle.
Reaming to
Preferably, the reference wall 008a 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 008a and the inner passage plate 008.
