Description

  The present invention relates to a paper sheet processing apparatus for transporting paper sheets such as banknotes.

  In a mail sorting apparatus that handles an automatic teller machine (ATM), a money counter, and a postcard, etc. of a financial institution, a paper sheet to be input is taken into the apparatus and various processes are performed. Each of these devices is divided into a plurality of units in consideration of the productivity and maintenance workability of the equipment to be enlarged. Of the paper sheets handled in each device, particularly, banknotes may have reduced strength, compromised or torn due to handling during the distribution process. In such an environment, a jam may occur in a paper sheet being conveyed between the units.

Some banknote depositing / dispensing machines divide a depositing / conveying unit and a stacker unit into upper and lower parts, slidably provide the stacker unit, and provide a tray device that receives a remaining banknote when it is pulled out (for example, Patent Document 1). ). According to this technique, when a banknote jam occurs at the boundary portion, if the stacker unit is pulled out, the remaining banknote is received by the tray device, so that it does not enter a gap in the apparatus.
Furthermore, as a paper sheet processing device, a paper sheet to be loaded is classified by a classification unit according to the discrimination result and stored in each type storage unit, and this classification unit can be pulled out from the apparatus main body. There is. Further, there is a device in which a shield curtain winding mechanism capable of covering the upper part is provided in the apparatus main body, and when the classification unit is pulled out, the shield curtain is also pulled out to cover the inside (for example, Patent Document 2). ). The above technique is for the case of pulling out in the horizontal direction in the horizontal conveyance path.

As another paper sheet processing machine, if any sheet is pulled out when there is paper remaining between the units, the paper sheet is jammed without being pulled up or down. There is one that can remove the kind (for example, Patent Document 3). This technology makes it possible to pull out in the direction perpendicular to the paper sheet transport direction and along the banknote, and discloses an opening mechanism that releases the force sandwiched by the paper sheet by the transport unit during the pull-out operation. is there.

Next, the delivery part in Example 1 of this invention is demonstrated.
FIG. 1 is a conceptual diagram of the delivery unit in the first embodiment of the present invention, FIG. 4 is an explanatory diagram of the delivery unit in the first embodiment of the present invention, and FIG. 5 is a control related to the delivery unit in the first embodiment of the present invention. It is a block diagram.
20 is the above-mentioned upper unit, and 30 is the lower unit. M is a bill as a paper sheet to be conveyed. Reference numeral 31 denotes a transport roller, which can hold and press the banknote M by means described later. The outer periphery of the transport roller 31 protrudes from the hole provided in the right guide 32 into the transport path 24. Reference numeral 33 denotes a pressure roller, which is provided to face the conveying roller 31. The pressure roller 33 has an outer peripheral portion protruding from the hole provided in the left guide 34 into the transport path 24. The banknote M can be conveyed in the direction of arrow D by rotating the conveyance roller 31 in the direction of arrow C.

  The transport roller 31 is strictly manufactured and managed in terms of concentricity and outer diameter size, and is pivotally supported on a frame by a shaft 31a, and is transported by a toothed belt (not shown) or the like (hereinafter referred to as a motor). It is combined with M1. The type of the motor M1 is a stepping motor. For example, if the conveyance amount is 1/180 inch per unit step, the conveyance amount of the sandwiched bill M can be managed by multiplying it by the rotation amount (number of steps) of the motor M1. . The pressure roller 33 is rotatably supported by a press shaft 33a. Furthermore, the surface of the pressure roller 33 is formed of a high friction member, and a pressing force F1 acts between the pressure roller 33 and the banknote M, and a corresponding frictional force acts.

  Reference numeral 41 denotes a transport roller provided in the lower unit 30, which can clamp and press the banknote M. The outer periphery of the transport roller 41 protrudes from the hole provided in the right guide 42 into the transport path 24. Reference numeral 43 denotes a pressure roller, which is provided to face the conveying roller 41. The pressure roller 43 has an outer peripheral portion that protrudes from a hole provided in the left guide 44 into the conveyance path 24. The banknote M can be transported in the direction of arrow D by rotating the transport roller 41 in the direction of arrow C.

  The transport roller 41 is also strictly manufactured and managed in terms of concentricity and outer diameter size, and is pivotally supported on the frame by a shaft 41a, and is transported by a toothed belt (not shown) or the like (hereinafter referred to as a motor). Combined with M2. The type of the motor M2 is also a stepping motor. For example, if the conveyance amount is 1/180 inch per unit step, the conveyance amount of the sandwiched bill can be managed by multiplying the rotation amount (step number) of the motor M2. The pressure roller 43 is also rotatably supported by a press shaft 43a. Further, the surface of the pressure roller 43 is formed of a high friction member, and a pressing force F2 is applied between the pressure roller 43 and the banknote M so that a corresponding frictional force is applied.

  The right side guide 32 and the left side guide 34 on the upper unit 20 side are formed in parallel, and the inner dimension of the banknote M on the conveying surface side is set to approximately 2 to 3 mm (exaggerated in the drawing). Further, the right side guide 42 and the left side guide 44 on the lower unit side 30 side are also formed in parallel, and the inner dimension of the bill conveyance surface side is set to approximately 2 to 3 mm (exaggerated in the drawing). And these right side guides 32 and 42 are nested so that passage of the banknote M is not hindered (comb teeth alternately enter, see FIG. 1). Also. Similarly, the left guides 34 and 44 are nested so as not to interfere with the passage of banknotes. In this state, the banknote M is exchanged. In the figure, a case where a tip surface bent in a direction of approximately 45 degrees is provided is shown.

  45 is a tray for jammed banknotes as a tray, which receives banknotes M removed by means described later, and is attached to the lower unit 30 that is the movable side. An upper portion of the jam bill tray 45 has a scraping guide portion 45a as a scraping member, and the shape of this portion is the same as that of the right guide 42 of the lower unit 30 as shown in FIG. When the lower unit 30 moves in the direction of arrow B shown in the figure, the right guide 32 and the left guide 34 of the upper unit 20 do not interfere with each other. FIG. 1 shows this state, which is substantially coincident with the outer shape indicated by the alternate long and short dash line. Further, as shown in FIG. 4, the jam bill tray 45 has a substantially “S” shape, but is not limited thereto.

  The distance between the transport roller 31 and the transport path roller 41 is set to be approximately equal to or shorter than the length of the bill M in order to transport the shortest bill M, and is sandwiched between at least one transport roller and the pressure roller during transport. . Further, the pressing force F2 acting on the conveying roller 41 side is set higher than the pressing force F1 acting on the conveying roller 31 side, and the bill M is engaged with both the conveying rollers 31, 41 as shown in FIG. When only the transport roller 41 side is rotated in the direction of arrow C in a state where the banknote M is in the state, the banknote M can be pulled out from the portion sandwiched between the transport roller 31 side.

  SE1 and SE2 are bill monitoring sensors, which are configured by arranging light emitting diodes and light receiving transistors so as to face each other, and pass an optical axis (a two-dot chain line shown in FIG. 4) in a direction in which the conveyance path 24 is cut off. An ON / OFF signal is obtained by A / D converting the output change of the light receiving transistor caused by the banknote M blocking the optical axis.

FIG. 5 is a control block diagram relating to the delivery section described above.
Reference numeral 19 denotes the storage unit described above, which can store a maintenance program downloaded from a host device or a removable storage medium (not shown), or can store a maintenance program in advance. Reference numeral 17 denotes an open switch that detects when the clerk opens the door 16. Needless to say, the control unit 18 controls the rotation of the motors M1 and M2 and performs various controls according to the detection information of the banknote monitoring sensors SE1 and SE2 and the open switch 17. Note that driver circuits and amplifier circuits are omitted.

  Next, banknote jam that may occur when the banknote M passes through the delivery section 40 will be described with reference to an explanatory view showing a transport system of the delivery section shown in FIG. As shown in FIG. 6A, the banknote M that is normally conveyed is conveyed in the direction of arrow D by rotating the conveyance roller 31 and the conveyance roller 41 in the direction of arrow C. Here, there are corner breaks and breaks of the banknote M, and banknote jams may occur in the delivery unit 40. As shown in FIG. 6B, when the banknote M is folded zigzag (bellows), it becomes clogged in the gap (2 to 3 mm) of the transport path 24 and is detected as a transport error. The control part 18 of ATM1 stops conveyance of the subsequent banknote M as abnormality generation within an apparatus.

Next, automatic recovery when a conveyance abnormality occurs will be described. FIG. 7 is an operation flowchart of the abnormality recovery process. S represents an operation step.
When the control unit 18 of the ATM 1 detects the occurrence of an abnormality in the device, it stops the conveyance of the subsequent banknote M. For example, when a plurality of banknotes M are being transported during the depositing operation, other banknotes M are also present on the transport path 24. Therefore, these banknotes M are transported to the temporary storage unit 23 or a reject box (not shown). And store. Moreover, if the feeding operation from the bill cassette 31 is in progress, the feeding of the next bill M is stopped.
S1. The controller 18 identifies the banknote jammed part and the conveyance direction (in the case of the first embodiment, the conveyance is in the direction of arrow D, and the banknote monitoring sensor SE2 has not detected the passage of the banknote. 6 (b), it is determined that the banknotes are jammed in the delivery unit 40. The control unit 18 starts an automatic jam removal operation by the failure recovery program.

First, the transport roller 31 and the transport roller 41 are rotated in the arrow H direction to transport the jammed banknote M in the arrow G direction in order to transport in the direction opposite to the transport direction when the jam occurs. If the conveyance roller 31 can pinch the banknote M so that it may show in figure, the jam banknote M will be conveyed by the arrow G direction, and will take in to the rejection store | warehouse | chamber etc. which were mentioned above. If the banknote monitoring sensor SE1 is not turned off (no banknotes) even if the transporting roller 31 and the transporting roller 41 are rotated for a predetermined time, jam removal is impossible.
It should be noted that conveyance for removing jam in a direction different from the conveyance direction at the time of jam occurrence is considered to be a problem on the leading end side of the banknote M due to the occurrence of banknote jam. It is because it can convey without. Therefore, for example, if the banknote M is being transported from the lower unit 30 to the upper unit 20 side in a dispensing operation, the transport direction for jam removal is opposite to the above. That is, the rotation direction of the motors M1 and M2 is controlled by the transfer direction.

S2. If automatic recovery is not possible due to the jam removal operation, the customer operation display unit 11 or a monitoring center (not shown) is notified to request a banknote removal operation by an attendant.
S3. When the clerk opens the door 16, the open switch 17 detects this, so the control unit 18 sends a signal indicating that the clerk is being handled to the monitoring center.
S4. The clerk performs the banknote removal operation of the delivery unit 40 in a predetermined procedure. Details will be described later.
S5. When the removal operation is completed, the lower unit 30 is pushed back to the normal position, and when the open switch 17 detects the closing of the door 16, the control unit 18 terminates the jam removal operation and starts the initial operation of the transport system. Transition.

S6. As an initial operation of the transport system, the transport motors M1 and M2 provided in the upper unit 20 and the lower unit 30 are synchronized and rotated for a predetermined time. If the bill monitoring sensors SE1 and SE2 and other monitoring sensors do not detect the bill movement also by this operation, the operation is ended as no bill on the transport path 24. Moreover, when a banknote movement is detected, the said banknote M is conveyed to a rejection store | warehouse | chamber.
The above initial operation is also performed when the removal of jammed banknotes is completed in step S1.

Next, the jam banknote removal operation which is the detail of step S4 in the flowchart of the abnormality recovery process shown in FIG. 7 will be described with reference to the operation process diagrams shown in FIGS.
As described above, even if the automatic recovery operation is performed, the banknote M is present in the delivery unit 40 as shown in FIG. When the door 16 is opened, the open switch 17 detects this, so the control unit 18 recognizes “door open” and puts the ATM 1 in a closed state.

When the clerk begins to pull out the lower unit 30 in the direction of arrow B, the jammed bill M is sandwiched between the left guide 34 and the right guide 42 as shown in FIG. However, since these guides are nested, they hold the banknote M but do not cut it. Subsequently, as shown in FIG. 8C, the upper unit 20 is separated from the positions of the right guide 32 and the left guide 34. If the lower unit 30 is continuously pulled out as it is, the jammed banknote M remains in the state shown in FIG. 8C, or the drawing is completed as shown in FIG. 3 while being placed on the upper surface of the lower unit 30 as shown in FIG. 8D. Pulled to position. Then, the clerk picks up the jam bill M.
As shown in FIG. 8D, it is assumed that, for example, the left guide 34 and the right guide 32 are caught when being pulled out while being placed on the upper surface of the lower unit 30. In this case, the scraping guide portion 45a of the jam bill tray 45 serves as a wall, and maintains the state of being placed on the upper surface of the lower unit 30.

  Moreover, as shown to Fig.9 (a), the case where the lower unit 30 is pulled out in the state in which a part of jam paper money M hooked on the upper unit 20 is assumed. In such a case, when the jammed banknote M is pulled out while remaining on the upper unit 20 side, the scraping guide portion 45a of the jammed banknote tray 45 acts. As shown in FIG. 9B, the jammed banknote M is sandwiched between the scraping guide portions 45a. Here, the guides are nested so that they hold the jammed banknote M but are not cut, and are separated from the positions of the right guide 32 and the left guide 34 of the upper unit 20 as shown in FIG. 9C. In this state, it is pulled out to the drawing completion position. Then, the jam bill M is picked up.

  Depending on the amount of jammed paper money M, the paper money may fall into the jammed paper tray 45 without being placed on the upper surface of the lower unit 30. In this manner, the lower unit 30 can be pulled out and the jammed banknote M can be easily picked up from the upper surface of the lower unit 30 or the jammed banknote tray 45. When the clerk pushes the lower unit 30 back into the ATM 1 and closes the door 16, the open switch 17 detects this (step S5) and executes the above-described processing.

  As described above, when the jammed banknote M generated in the delivery unit 40 remains, when the lower unit 30 is pulled out, the right side guide 42 and the discharge guide unit 45a perform the two extractions. After that, it is only necessary to pick up the jam bill M, which is very convenient. In addition, although the delivery part 40 is described in two places in FIG. 3, it cannot be overemphasized that it can mount in both.

Next, Example 2 of the present invention will be described.
FIG. 10 is an explanatory diagram of the delivery unit in the second embodiment, and FIG. 11 is a perspective view of the left guide in the second embodiment. The difference with the delivery part of Example 1 is that the left side guide on the lower unit side is rotatable as shown in the figure. Therefore, in the following description, only different parts will be described, the same parts as those in the first embodiment will be denoted by the same reference numerals, and the description thereof will be omitted.
As shown in FIG. 11, the left guide 46 is rotatably supported by a press shaft 43a, and arm portions 47 are formed at both ends. This arm portion 47 has a latching portion 47a above, and a small hole 47b below the press shaft 43a.

  The hook portion of the coil spring 48 is inserted into the small hole 47b. The coil spring 48 is stretched between frames (not shown), and generates an urging force to rotate the arm portion 47 in the clockwise direction in FIG. The latching portion 47a is in a positional relationship such that it comes into contact with the protruding portion 25 provided on the upper unit 20 side. In a state where the lower unit 30 is housed, that is, in a movable state of the ATM 1, the latching portion 47 a comes into contact with the projection portion 25, and an optimum interval (2 to 3 mm) for transporting the banknote M is secured in the delivery portion 40. It will be.

The automatic restoration at the time of occurrence of the conveyance abnormality in the second embodiment is as described above according to the operation flowchart of FIG. 7, and the procedure of the banknote removal operation is the same. Accordingly, only the main part will be described with reference to the diagram shown in FIG.
When the clerk starts pulling out the lower unit 30 in the direction of arrow B, the hooking portion 47a at the tip of the arm portion 47 rotates (in the direction of arrow E) toward the protruding portion 25 according to the action of the coil spring 48. As shown in FIG. 11, the arm portion 47 is integrated with the left guide 46, so that the arm portion 47 rotates around the press shaft 43 a as a rotation center and comes into contact with the right guide 42 and stops.
In other words, the front end portion P (upper part in the figure) of the left guide 46 and the front end part (upper part in the figure) of the right guide 42 have clamping means for clamping the jammed banknote M. The clamping pressure at this time is experimentally determined by the setting of the coil spring 48.

  In this way, if the lower unit 30 is pulled out to the end while holding the jam bill M, the clerk can pull the jam bill M upward against the clamping pressure. In addition, depending on the degree of jam, when a load stronger than the clamping pressure is applied, the jammed banknote M may be pulled out from the clamping unit. At this time, the jam bill M is removed by the action of the jam bill tray 45 described in the first embodiment.

  As described above, according to the second embodiment, the jammed banknote can be pulled out while being sandwiched between the side to be pulled out, that is, the lower unit, and thus there is an effect that the removal becomes easy. Furthermore, there is an effect that it is possible to work with peace of mind without being blown away by a gust of wind even when the equipment is installed outdoors. In addition, although the Example in which the pull-out direction of the lower unit is a direction orthogonal to the transport direction has been described, the present invention is not limited to this. That is, the direction may be 45 degrees or 60 degrees.

Although the above example demonstrated the jam banknote in the automatic teller machine, it is not limited to this. For example, it is not limited to ticket vending machines and banknotes such as event admission tickets, lottery tickets, and winning horse voting tickets. Needless to say, it can be used for, for example, mail sorting machines, office equipment that reads, prints, and copies various forms.
