Description

[Detailed description of the invention] [Technical field to which the invention pertains]

This invention relates to an apparatus for handling banknotes, such as an automatic deposit machine or an automatic money exchange machine, in which banknotes stacked and stored between the storage section conveyor 1~ and the bottom plate of the storage chamber are also used for dispensing. The present invention relates to a method of raising and positioning a bill storage bottom plate in response to a command and then coupling it to a bill dispensing mechanism in order to smoothly perform a bill dispensing operation for dispensing, that is, a bill dispensing method.

[Prior art and its problems]

In order to implement the method described above, the following problems need to be solved. That is, in the case of paying out banknotes, it is necessary to reliably pay out the stored banknotes in order from the first one with a relatively strong force. Contact must be made with strong pressure.

[Purpose of the invention]

It is an object of the present invention to solve the above-mentioned problems and to provide a method for smoothly and reliably dispensing banknotes stored in a stack for dispensing.

[Key points of the invention]

The key point of the present invention to achieve the above object is that the bottom plate of the banknote storage chamber can be raised and lowered in parallel, and the degree of this raising and lowering can be adjusted to achieve a contact pressure that meets the purpose. . That is, for example, a support is attached perpendicularly to the surface of the bottom plate, and this branch is supported by guide rollers so that it can move up and down. On the other hand, one of these branches is provided with a rank, and the pinion attached to the motor is engaged with this rank. In other words, the sole is raised and lowered by the rotation of the motor. The degree of elevation of the bottom plate is adjusted by the following motor operation. When dispensing banknotes, the motor is rotated in the forward direction for a certain period of time to raise the bottom plate. Within that time, at least the bottom plate reaches its upper limit, and the motor is stopped by the contact pressure between the banknotes and the storage section bending bell I. In other words, the external load applies a brake to the motor shaft. The motor then stops at the said time. In this way, the banknote surface is in relatively strong contact with the surface of the storage section conveyor 1, in other words, it is positioned at a substantially constant position. More motor system? ff1l is performed, for example, by a combination of a microcomputer and a non-contact sequence circuit.

[Embodiments of the invention]

An embodiment of the present invention will be described in detail with reference to the perspective view of FIG. 1 together with its related parts. In FIG. 1, the entire device for storing banknotes schematically includes a banknote storage gate mechanism 19, a banknote storage mechanism 20, a banknote position regulation lever 26, and a banknote storage bottom plate elevating mechanism 3o, which is the direct object of the present invention. It consists of a banknote feeding mechanism 40. The general structure and operation of the above main elemental mechanisms will be described below. The banknotes 10 carried in from the direction of arrow R are turned to the storage side by the direction change guide rail 11 of the banknote storage gate mechanism 19, and are sandwiched between the belt 5 and the pressing roller 12 provided at the end of the direction change guide rail 11. banknote storage mechanism 2
0. Next, the banknote feeding mechanism 40 is installed so as to fit into a part of the banknote storage mechanism 20. In other words, the banknote feeding roller 42
is located above the tip of the bill 10 in the storage position. 43.
Reference numeral 44 denotes a set of rollers for preventing the passage of multiple bills, and has the function of allowing only one bill to pass between the two. This bill dispensing roller 42. The multiple sheet passage prevention rollers 43 and 44 are driven by the drive shaft 41.
It is rotated in the direction of the arrow via belt pulleys 45A, 45B and toothed belt 45C. Banknote feeding roller 42. Multiple sheet passage prevention roller 43°44
A holding frame 49 that holds together the components is rotatably installed around a rotation shaft 41. Further, this holding frame 49 includes an electromagnetic actuator 46. A spring 47 and a push shaft 48 are provided. Note that the banknote feeding roller 42. Multiple sheet passage prevention roller 4
3 and the push shaft 48 are actually incorporated into the banknote storage mechanism 20, which is schematically illustrated by the two-dot chain line. When a banknote feeding command is issued, first, the banknote storage bottom plate elevating mechanism 3
0 operates, the bottom plate 25 rises, and stops with the surfaces of the stored banknotes 1 and OA in strong contact with the conveyor belt 5. Then, the electromagnetic actuator 46 operates, and the holding frame 49
is rotated clockwise to press the outer circumferential surface of the bill feeding roller 42 against the surface of the stored bill 10. At the same time,
A push shaft 48 provided on the holding frame 49 pushes one end of the banknote position regulating lever 26 and rotates it clockwise to release the blocked state of the front end surface of the stored banknote 10Δ. In this state, the banknote feeding roller 42 rotates a number of times corresponding to the predetermined number of banknotes, and the stored banknotes 10A are fed out in order from the top in the direction of the arrow S by the frictional force of the rubber uneven portion provided on the outer periphery. Furthermore, multiple sheet passage prevention rollers 43, 44
Accordingly, only one banknote 10 is allowed to pass. When a predetermined number of sheets have been fed out, the electromagnetic actuator 46 is turned off based on the command, and the holding frame 4 is turned off by the spring 47.
9 rotates back counterclockwise. In this way, the outer circumferential surface of the banknote dispensing roller 42 separates from the surface facing the stored banknotes 10. At the same time, the banknote position regulating lever 26 is released from the push shaft 48, rotated counterclockwise by the spring 28, and returns to the original banknote blocking position. During the return operation process of the banknote position regulation lever, if there are banknotes remaining at the multiple-sheet passage prevention rollers 43, 44, those banknotes are pushed back to the normal storage position, that is, the position is corrected. The banknote storage bottom plate elevating mechanism 30 functions to smoothly remove the stored banknotes 10A from the surface as described above. That is, a column 31 provided on the bottom plate 25 is guided and supported by guide rollers 32 so as to be movable in the vertical direction, and a rank 33 is attached to this column 31. A pinion 34 meshes with this rack 33, and this pinion 34 is further engaged with a gear 36A. It is connected to the motor 37 through 36B. Based on the bill dispensing command, the motor 37 first moves the bottom plate 2
It rotates so as to raise the banknote 5 by 1, and comes into contact with the conveyor belt 5 of the banknote storage mechanism 20 and stops. Next, the operation of the motor 37 will be described in more detail. That is, in response to the dispensing command signal, the motor 37 rotates in the normal direction for a set time and then stops. At this time, the surface of the banknotes 10Δ stacked and stored on the bottom plate 25 is in a state of strong contact pressure with the conveyor belt 5. Therefore, the banknote feeding roller 42,
When in operation, it comes into reliable contact with the surface of the banknote 10Δ and performs the dispensing operation reliably. Note that control of the motor 37 will be explained in detail later. Next, the bill position regulating lever 26 and the bill dispensing mechanism 40, which are closely related to the bill dispensing operation, will be explained in detail with reference to FIG. 2. Figure 2 shows its side view. First, the configuration of this mechanism will be explained. In FIG. 2, the banknotes 10 are stored in a stacked manner in sequence on the bottom plate 25 of the storage chamber. 26 is a banknote position regulation lever;
27 is a rotation shaft that rotatably supports this position regulating lever 26, 28 is a spring, and 48 is a holding frame 4 of the banknote feeding mechanism 40.
A push shaft is fixed to 9, and 42 is a roller for feeding out banknotes, and a part of its circumference is provided with a rubber uneven part. 43 and 44 are a well-known set of rollers for preventing multiple banknotes from passing as described above. The upper roller 43 for preventing the passage of multiple sheets is composed of three thin disks arranged at a certain interval in the axial direction. Further, similarly, the lower one 44 has two disks having a smaller diameter than the above-mentioned disks arranged between the above-mentioned disks. The outer peripheries of both discs are placed so that they touch each other with a slight spacing between them. This interval is adjustable. Also, normally, the larger disc is made of a metal material, and the smaller disc is made of a soft material on the outer periphery.The upper multiple-sheet passage prevention roller 43 is attached to the drive shaft 41, It is also connected in the same direction as the bill dispensing roller 42 so as to equalize the linear velocity on the outer periphery.In addition, the lower multiple bill passage prevention roller 44 cannot rotate in the dispensing direction, but can rotate in the opposite direction. A one-way clutch is built in. Mainly, the feed roller 425, the multiple bill passage prevention roller 43, and the frame 4 that holds them.
9 constitutes a banknote feeding roller unit. Drive shaft 4
1 rotates slightly clockwise in the figure. The holding frame 49 of the banknote feeding mechanism 40 is rotatably supported coaxially with the drive shaft 41. Further, the holding frame 49 is connected to a movable part of the electromagnetic actuator 46. Further, a spring 47 is attached to the holding frame 49 to apply a rotational force to the holding frame 49 in a counterclockwise direction. A stopper 478 for preventing rotation of the holding frame 49 is provided on the frame (not shown). Incidentally, FIG. 1 fa) is a perspective view of the arrangement of each of the above-mentioned members, so that the relative positions thereof can be clearly understood. That is, there are three banknote feeding rollers 42, and multiple banknote passage prevention rollers 43.4.
There are two sets of number 4, which are arranged alternately with the rollers 42 in the axial direction. Next, for the sake of convenience, the operation of this mechanism will be explained separately for the case of storing banknotes and the case of dispensing banknotes. first,
In the case of storing banknotes, the solid line in FIG. 2 corresponds to the case. That is, from the surface of the stored banknote 10A, the banknote feeding roller 4
The outer peripheral surfaces of No. 2 are separated from each other. At the same time, the banknote position regulation lever 26 is also located at the position indicated by diagonal lines, and the regulation surface 26a at the tip thereof blocks the front surface (left side surface in the figure) of the banknote 10A. Next, when a bill payout command is issued, the movable part of the electromagnetic actuator 46 operates upward based on the command signal, and the holding frame 49 is rotated clockwise about the drive shaft 41. At the same time, the push shaft 48 fixed to the holding frame 49 pushes the upper edge of the banknote position regulating lever 26,
The lever 26 rotates in the forward and backward direction and moves to the position indicated by the two-dot chain line in the figure. At the same time, the outer peripheral surface of the bill feeding roller 42 comes into contact with the surface of the bill 10. In the above state, when the bill dispensing roller 42 is rotated clockwise together with the multiple bill pass prevention roller 43 by the rotation of the first section mover 41, the stored bills are sequentially dispensed one by one. Then, the fed bills are reliably passed one by one by a set of multiple bill passage prevention rollers 43 and 44. In other words, even if two banknotes try to pass through the gap between the multiple-sheet passage prevention rollers 43 and 44, the lower banknote will separate from the upper banknote due to the large friction with the rubber surface of the roller 44. and stay in place. The banknotes that have passed through these are sent to the delivery roller 51 shown in FIG.
and a pressing roller (not shown) installed opposite to this. Naturally, the drive shaft 41 is commanded to rotate at a speed corresponding to the number of coins to be dispensed, and the electromagnetic actuator 46 performs a suction operation only during the dispensing period. When the dispensing command is completed, the electromagnetic actuator, knee 46
The operation is canceled, and each part of the banknote feeding mechanism also returns to the solid line display position. The push shaft 48 then moves to the shaded position. Simultaneously with this movement, the bill position regulating lever 26 is rotated counterclockwise by the spring 28 to a position where it hits the push shaft 48 and returns to its original position (the position shown by diagonal lines). If there is a banknote stuck at the multiple-sheet passage prevention rollers 43 and 44, the banknote position regulation lever 26
The return operation pushes it back to the normal storage position. In this way, it becomes possible to store banknotes. Note that 52 is a bill feeding detector, and 53 is a bill shape detector, which are arranged side by side on the feeding surface of the feeding roller 51, respectively. The bill delivery detector 52 literally detects that a bill has been sent out, and consists of a combination of a light emitting diode as a light emitting part and a phototransistor as a light receiving part, and detects the passage of a bill by a decrease in the intensity of the received light. The bill-shaped detector 53 also consists of a combination of a light-emitting diode as a light-emitting part and a phototransistor as a light-receiving part, and depending on the intensity of transmitted light when the bill passes, the number of bills is 1 or 2 or more. Detect whether they overlap. Next, control of the motor 37 will be explained with reference to FIGS. 3 to 6. FIG. 3 shows the main circuit including motor 37, which is a condenser motor. Forward and reverse rotation of the motor 37 is performed by replacing the two wires of the auxiliary coil. MCB is a wiring breaker, TI (R is a thermal relay heater, MCa and MCb are electromagnetic switches for forward rotation and reverse rotation, respectively. The opening/closing control of the main circuit described above is performed by the program shown in the flowchart in Fig. 4). This is carried out by a microcomputer that has written the following into a storage device ROM, and a non-contact logic circuit connected thereto as shown in Fig. 5. First, the operation of the microcomputer will be explained based on the flowchart shown in Fig. 4. Based on the command, the payout motor is started in step S1. Next, in step S2, a signal Sa is output. 37. That is, the signal Sa turns on the forward rotation electromagnetic switch MCa through the output circuit as described later. In step S3, the motor rotates in the forward direction for a preset time Ta. It is determined whether or not the rotation is continued.The time Ta is about 500 to 600 m5.If NO, forward rotation continues.If YES, step S4
At this point, a signal Sc, ie, a stop signal of voltage level L, is output. Next, in step S5, a solenoid for pressing the bill delivery roller onto the bill surface is turned on. In this manner, the banknotes are fed out, and then a plurality of banknotes are passed through the passage prevention roller and sent out for dispensing. In step S6, it is determined whether the bill has been sent out. The delivery of banknotes is detected by the banknote delivery detector 52, which is a photoelectric switch described above. If YES, it is further determined in step S7 whether only one banknote or two or more banknotes are stacked. This is detected by the banknote type detector 53. If the result is YES, the determination is repeated in step S8 until the number of coins to be sent out reaches the number of coins ordered to be paid out. When the number of bills to be commanded to be dispensed is reached, the solenoid for bill feeding is turned off in step S9, and then in step SI
At O, the banknote feeding motor is turned off and the program ends. On the other hand, if the number of sheets to be sent out is 2 or more in step S7,
In step S13, the signal Sr is output, and the process ends. This signal Sr is called a reject signal,
In response to this signal, the banknotes sent out at this time are stored in a specific container in the device as unsuitable for dispensing to the customer due to the risk of erroneous accounting, and are collected later. Note that if it is determined in step S6 that the banknote has not been sent out, the process proceeds to the next step S.
At ll, it is determined whether the time Ts has elapsed. That is, if no banknotes are fed out even after waiting for a certain predetermined time Ts, it is assumed that the banknotes have not been fed out by the feeding roller, or even if they are fed out, they are stuck at the passage prevention roller, and the following measures are taken. . Note that the time Ts is about 200 to 300 m5. This means is the subroutine of step S12, "Banknote
"adjustment process of contact pressure between delivery rollers". The purpose of this subroutine is to assume that the cause of banknotes not being fed out is inappropriate contact pressure between the banknotes and the delivery roller, and to perform adjustment processing accordingly. After this process, the process returns to step S5 to turn on the banknote feeding solenoid. Next, a non-contact logic circuit and its operation will be explained based on FIG. This circuit consists of two AND circuits each having an L active input terminal and an output terminal, and a flip-flop circuit FFI.
, FF2 are combined as shown in the figure, and the flip-flop circuits FF1 . This is a motor forward/reverse rotation circuit that uses a so-called parallel priority circuit that provides a priority function between FF2. As mentioned above, as the output of the microcomputer, the L level Sa, which is the motor forward rotation signal, and the reverse rotation signal S
b. Input the stop signal Sc to this circuit. The signal Sa causes the output 01 of the flip-flop circuit FFI to go to level H, and at the same time, the priority function prevents the signal sb from being applied. Similarly, when the output Q2 of the flip-flop circuit FF2 is at level H due to the signal sb, the signal Sa is not applied. Also, since it is a reset priority flip-flop circuit, the priority function works between the cent and reset inputs, and the stop signal Sc causes the output []
1. Q2 becomes L. In addition, the output Ql, 02 is power amplified through 9 output circuits (not shown) located in the dotted line portion of the figure, and the electromagnetic switches MCa, MC for forward and reverse rotation of the motor are amplified.
They are input to coils MCI and MC2 of b, respectively. In conclusion, time chart 1-
is shown in Figure 6. FIG. 6(a) shows the signal Sa, FIG. 6(b) shows the signal Sc, and FIG. 6(C) shows the ON/OFF state of the excitation coil port 1 of the electromagnetic switch MCa. ■, By the level signal Sa, the electromagnetic switch coil MC
I is energized, the electromagnetic switch MCa shown in FIG. 3 is turned on, and the motor is driven to rotate in the forward direction, raising the banknote storage bottom plate. Then, after the preset time Ta has elapsed, L
The coil l'lc1 is demagnetized by the level signal Sc, the electromagnetic switch MCa is turned OFF, and the motor is stopped. In other words, the bill storage bottom plate is in a state where it has strong contact pressure with the bill storage section conveyor belt.

【Effect of the invention】

Due to the above-described configuration and operation, the present invention has the following advantages. (l) In the case of bill dispensing, prior to the dispensing operation, the stored bill surface and the storage unit conveyor belt surface are brought into a state of strong contact pressure. In other words, the bill is positioned at a substantially constant position relative to the opposing dispensing roller, so that the bill is dispensed. The operation is performed smoothly and reliably. (2) According to the embodiment, the adjustment of the contact pressure is performed by raising and lowering the bottom plate of the banknote storage chamber by simple forward and reverse rotation control of the motor. It is advantageous not only in terms of reliability but also in terms of cost.
