Patent Issued for Banknote Inclination Correction Device and ATM

August 13, 2014



By a News Reporter-Staff News Editor at Journal of Engineering -- According to news reporting originating from Alexandria, Virginia, by VerticalNews journalists, a patent by the inventors Wang, Peng (Guangzhou, CN); Liu, Dongbo (Guangzhou, CN), filed on July 4, 2012, was published online on July 29, 2014.

The assignee for this patent, patent number 8789828, is GRG Banking Equipment Co., Ltd. (Guangzhou, CN).

Reporters obtained the following quote from the background information supplied by the inventors: "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.

"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', parallel to the banknote transmission passage 003 and a component force F'.sub.b perpendicular to the banknote transmission passage 003 imparted from the correcting wheel 001. Under the action of the component force F'.sub.a, the banknote is transmitted forward in the banknote transmission passage 003; meanwhile, under the action of the component force F'.sub.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.

"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'.sub.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 addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "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.degree. 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."
