Description

  The present invention relates to a banknote recognition apparatus, and more particularly to a banknote identification apparatus that performs processing for identifying and storing banknotes inserted in a vending machine, a ticket vending machine, a parking lot adjustment machine, and the like.

  In a vending machine capable of handling banknotes, a banknote identification device is attached to the back side of the front door. A banknote identification device includes a banknote inlet guide section that takes in a banknote inserted therein, a banknote identification section that identifies a banknote that has been taken in, a banknote storage section that stores the identified banknote, and an identified banknote And a pusher portion to be pushed into the bill storage portion. The banknote inlet guide part is attached to the front side end of the rectangular main body frame, and the banknote identification part is attached to the back side of the main body frame corresponding to the banknote inlet guide part. The pusher part is attached to the back side of the main body frame adjacent to the banknote recognition part, and the banknote storage part is detachably attached to the pusher part. The banknote storage unit is disposed in the pusher part in the vicinity of the pusher plate, and when the banknote identified by the banknote identification unit is fed into the gap, the banknote is pushed into the banknote storage part by the pusher plate. It is configured to be loaded and stored (see, for example, Patent Document 1).

  In such a banknote identification apparatus, the banknote taken in by the banknote inlet guide part is identified while passing the banknote identification part, and what can be correctly identified here as a banknote is stored in the banknote storage part. About what was not correctly identified as a banknote, it is comprised so that it may return from a banknote entrance guide part.

The bill entrance guide unit includes a bill entrance opening and a roller that takes in the inserted bill and conveys it toward the bill recognition unit. When a bill is inserted into the bill entrance opening, the roller is driven to rotate, and the roller operates to sandwich the inserted bill and send it to the bill recognition unit. When returning the inserted banknote, the roller is driven to rotate in the reverse direction and conveys the banknote passed from the banknote recognition unit toward the banknote entrance opening. The roller is stopped when the bill is conveyed so that the leading edge of the bill comes out of a predetermined length from the bill entrance opening. As a result, the vicinity of the rear end of the banknote is sandwiched by the roller and is held by the frictional force with the roller. Thereby, since the front-end | tip part is hold | maintained in the returnable state which hung down from the banknote entrance opening part, the banknote which should be returned is not blown away by a wind, A user is such It can be received by pulling out the banknote.
Japanese Patent No. 4136605

  However, in the conventional banknote recognition device, when the banknote is returned, the banknote is held by the frictional force of the roller, and since the held banknote is pulled out from the roller, it is configured to be released from the banknote recognition apparatus. Or the banknote with a crack or the banknote with which the waist became weak had the problem of being damaged when pulling out from a roller.

  This invention is made | formed in view of such a point, and it aims at providing the banknote identification device which reduced the possibility of the banknote damage at the time of return operation | movement.

In the present invention, in order to solve the above problems, a banknote inlet guide section for introducing a banknote inserted from a banknote inlet opening section along a banknote transport path, and a banknote for identifying a banknote taken in by the banknote inlet guide section. A banknote recognition apparatus comprising: an identification unit, wherein a banknote that could not be identified by the banknote identification unit is returned from the banknote entrance guide unit; returned includes a return banknote holding lever for holding the banknotes released toward the bill inlet opening, the return banknote holding lever, shaft ends extend in a width direction of the bill feeding path is journalled And a return bill holding arm and a spring locking arm fixed to the shaft so as to extend in a direction substantially orthogonal to the shaft, and the return bill holding lever about the shaft By rotating, a part of the arc-shaped banknote conveyance path formed along the outer periphery of a roller that sandwiches the banknote inserted from the banknote entrance opening and feeds it to the banknote recognition section is held by the return banknote. The arm is reciprocally movable, and the return banknote holding arm is positioned in the vicinity of the nipping position of the roller when the spring locking arm is pulled by a spring in a standby state, and the banknote is inserted from the banknote entrance opening. When it is inserted, it is pushed away by the banknote, moves to the banknote recognition part side from the pinched position of the roller, and when the banknote is returned toward the banknote entrance opening, the banknote returned from the banknote recognition part Is moved to the banknote conveyance path closer to the banknote entrance opening than the nipping position of the roller, and the return paper is increased by the tension of the spring increased by the rotation of the shaft. The bill holding arm is missing from the pinching position of the roller holding by pressing the upper inner wall of the bill transport path, the bill discrimination apparatus is provided, characterized in that.

According to such a bill recognition device, the return bill is not held by using a bill conveying device having a large frictional force, but is held from the return bill holding lever by separately providing a return bill holding lever. It is possible to reduce the possibility of the banknotes being damaged when the banknotes being drawn are pulled out.

The banknote recognition device having the above configuration can use a material with a small frictional force as a return banknote holding lever , so that it is possible to prevent an accident that the banknote is damaged when the banknote being held is pulled out. There is.

  Moreover, since the banknote conveyance roller is not used for holding the returned banknote, early wear of the roller can be prevented. Furthermore, since it can be configured to hold the returned banknote when it is removed from the banknote transport roller, it is not necessary to accurately position the returned banknote, and high-precision drive control of the banknote transport roller is also possible. It becomes unnecessary.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, taking as an example the case of application to a vending machine.

It is a partial expanded sectional view.

  The banknote recognition apparatus has a rectangular main frame 10 that is elongated in the vertical direction in FIG. 1, and is configured by attaching various functional units made for each unit to the main frame 10. A bill entrance guide portion 20 is attached to the front side of the main body frame 10. This banknote inlet guide part 20 has a banknote inlet opening 21 for inserting or returning banknotes. A bill recognition unit 30 for identifying the inserted bill is attached to the back side of the main body frame 10 at a position corresponding to the bill entrance guide unit 20, and a pusher unit 40 is provided adjacent to the bill recognition unit 30. Has been. A bill storage unit 50 (see FIG. 2) in which the identified banknote is pushed and stored by the pusher unit 40 is detachably mounted in the frame of the pusher unit 40.

  As shown in FIG. 2, the bill recognition unit 30 attached to the main body frame 10 includes a transport roller 31 located in the back of the bill entrance opening 21 and a transport roller 32 located on the side far from the pusher unit 40. doing. The conveyance roller 31 cooperates with the taking-in roller 22 attached to the banknote entrance guide part 20 to sandwich the banknote inserted from the banknote entrance opening 21 and introduced along the banknote transport path 24, and by friction engagement. It is configured to be pulled in. The banknote entrance guide unit 20 is provided with a tension roller 23 that cooperates with the transport roller 32 so that the banknotes transported by the transport roller 31 and the take-in roller 22 are fed into the banknote recognition unit 30.

  The bill recognition unit 30 includes tension rollers 33 and 34 that cooperate with the transport rollers 31 and 32, and configures a bill transport path 35. Various sensors (not shown) for detecting the characteristics of the banknote are arranged in the banknote transport path 35, and the banknote recognition unit 30 determines the denomination and authenticity while transporting the banknote through the banknote transport path 35.

  The legitimate banknote identified by the banknote identification unit 30 is sent to the pusher unit 40 by the transport roller 31 and the tension roller 33. The banknotes fed into the pusher unit 40 are pushed into the banknote storage unit 50 by a pusher plate that moves in parallel toward the banknote storage unit 50. The pushed banknotes 60 are sequentially stacked and stored in the banknote storage unit 50.

  As a result of identification by the banknote recognition unit 30, banknotes that are not recognized as valid are conveyed toward the banknote inlet guide unit 20 by reversely driving the transport rollers 31 and 32, and returned from the banknote inlet opening 21. The

  The banknote inlet guide unit 20 also includes a return banknote holding lever 25 as return banknote holding means for holding the banknote to be returned in the banknote transport path 24 when returning the banknote. As shown in FIG. 3, the return bill holding lever 25 includes a shaft 25a, a return bill holding arm (first arm) 25b and a spring locking arm (second arm) 25c fixed to the shaft 25a. In addition, preferably, the shaft 25a, the return bill holding arm 25b, and the spring locking arm 25c are integrally formed by resin molding. The return bill holding arm 25b and the spring locking arm 25c are fixed to the shaft 25a so as to extend from the shaft 25a in a direction orthogonal to each other, for example, and a locking hole 25d is formed in the spring locking arm 25c. ing.

  A pair of take-in rollers 22 are arranged at both ends in the width direction of the bill transport path 24, and a return bill holding lever 25 is installed inside the take-in roller 22. As shown in FIG. 4, the shaft 25 a of the return bill holding lever 25 is pivotally supported in the vicinity of an extension line of the rotation shaft of the take-in roller 22. The return banknote holding lever 25 reciprocates around a part of the arc-shaped banknote conveyance path 24 in which the vicinity of the tip of the return banknote holding arm 25b is formed along the outer periphery of the take-in roller 22 by rotating about the shaft 25a. It can be moved. In the state shown in FIG. 4, the banknote 61 transported in the direction of the arrow 61 a toward the banknote inlet opening 21 is removed from the sandwiched position of the transport roller 31 and the take-in roller 22 by the return operation, and the transport force is lost. The rear end portion of the banknote 61 is held and held between the front end of the return banknote holding arm 25b and the upper inner wall 26 of the banknote transport path 24 opposite thereto. At this time, since the spring locking arm 25c is pulled in the direction of the arrow 25e by a later-described tension coil spring 27 locked in the locking hole 25d, the return bill holding arm 25b is centered on the shaft 25a. A force that rotates in the clockwise direction acts, and the force holds the bill 61 returned by pressing the bill 61 against the upper inner wall 26 of the bill conveyance path 24. Since the banknote 61 is held, the banknote 61 is prevented from falling from the banknote entrance opening 21 and being blown off by the wind.

Next, in the banknote identification device having the above-described configuration, each operation in the standby state, the banknote insertion state, and the banknote return state of the return banknote holding lever 25 provided in the banknote entrance guide unit 20 will be described.

5 is an operation explanatory diagram of the return banknote holding lever in the standby state, FIG. 6 is an operation explanatory diagram of the return banknote holding lever in the banknote insertion state, and FIG. 7 is an operation explanatory diagram of the return banknote holding lever in the banknote return state. In FIGS. 5 to 7, a part of the banknote entrance guide part 20 and the banknote recognition part 30 of the banknote recognition apparatus is shown in a simplified manner for explaining the operation of the return banknote holding lever 25.

  First, in the standby state of the bill recognition device, as shown in FIG. 5, the return bill holding lever 25 is pivotally supported at positions where both ends of its shaft 25a are close to the rotation axis of the take-in roller 22, and a spring locking arm. 25c is pulled downward in the figure by the tension coil spring 27. Thereby, the return banknote holding arm 25b of the return banknote holding lever 25 moves the banknote transport path 24 in the vicinity of the sandwiching position of the transport roller 31 and the take-in roller 22 in the banknote transport path 24 bent in an L-shaped cross section. Located to block.

  When the bill 61 is inserted into the bill entrance opening 21 of the bill entrance guide 20, the insertion is detected by a sensor (not shown), and the transport roller 31 is rotationally driven in the counterclockwise direction. Along with this, the take-in roller 22 provided so as to be pressed against the transport roller 31 rotates in the clockwise direction, so that the inserted bill 61 is sandwiched between the transport roller 31 and the take-in roller 22 and given a transport force. It is done. As shown in FIG. 6, the banknote 61 to which the transport force is applied advances by pushing back the return banknote holding arm 25 b of the return banknote holding lever 25 positioned so as to block the banknote transport path 24, and the banknote recognition unit 30. Go to.

  As a result of identifying the banknote 61 inserted by the banknote recognition unit 30, if it cannot be identified as a valid banknote, the transport rollers 31 and 32 are driven to rotate reversely and transported to the banknote recognition unit 30. The withdrawal of the banknote 61 that has been started is started. At this time, since the return banknote holding lever 25 is in the same operation state as the standby state shown in FIG. 5, the banknote 61 to which the transport force is applied by the transport roller 32 and the tension roller 23 is as shown in FIG. 7. The return banknote holding arm 25b of the return banknote holding lever 25 is pushed away and conveyed toward the banknote inlet opening 21. At this time, in conjunction with the push-back operation of the return bill holding arm 25b, the spring locking arm 25c operates in the direction of pulling the tension coil spring 27, so that the spring force is increased.

  When the trailing edge of the banknote 61 passes through the nipping position of the transport roller 31 and the take-in roller 22 and the transport force of the banknote 61 is lost, the banknote 61 tends to fall by its own weight. However, at this time, the return banknote holding arm 25b of the return banknote holding lever 25 receives an acting force rotated clockwise by the tension coil spring 27 with increased spring force, and the rear end portion of the banknote 61 is moved to the banknote. It acts to press against the upper inner wall 26 of the transport path 24. Thereby, the banknote 61 from which the transport force has been lost is held by the return banknote holding lever 25 at a position where the transport roller 31 and the take-in roller 22 have been sandwiched without falling or being blown off by wind. Will be.

  Unlike the rubber conveyance roller 31 and the take-in roller 22, the return banknote holding arm 25b is a resin having a small frictional force, so that the banknote 61 is damaged when the banknote 61 held by the return banknote holding arm 25b is pulled out. It is possible to greatly reduce the possibility of the occurrence. Moreover, since the conveyance roller 31 and the taking-in roller 22 do not hold the returned banknote, the surface wear is not promoted. Furthermore, since the conveyance roller 31 and the taking-in roller 22 do not need to stop conveyance at the position where the bill 61 is sandwiched when the bill is returned, the drive control of the conveyance roller 31 can be simplified.

It is a perspective view which shows the external appearance of a banknote identification device. It is sectional drawing which shows schematic structure of a banknote identification device. It is a perspective view which shows the external appearance of a return banknote holding lever. It is a partial expanded sectional view of the A section of FIG. It is operation | movement explanatory drawing of the return banknote holding lever in a standby state. It is operation | movement explanatory drawing of the return banknote holding lever in a banknote insertion state. It is operation | movement explanatory drawing of the return banknote holding lever in a banknote return state.
