Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a mechanism for discharging and collecting banknotes fed into a stacker, and is particularly applicable to automatic teller machines and automatic cash dispensing machines. Regarding what is suitable for.

[Conventional technology]

FIG. 1 shows an example in which this type of banknote discharging and collecting mechanism is utilized in an automatic cash dispenser. In the figure, when the banknotes are discharged, the banknotes 2 in the cassette 1 are fed out one by one by the separating mechanism 3, and the banknotes 2 are sent out one by one by the separating mechanism 3,
A specified number of sheets are fed into the stacker 4 after passing between 0 and 30, and are deposited. The designated number of banknotes 8 stacked on the stacker 4 is pushed out to the receiving slot 6 by the advance of the fork 5, so that the user can take them out. A pawl 7 is interlocked with the fork 5, and the pawl 7 presses down the banknotes on the stacker 4 when the fork 5 moves forward and backward, and only when the fork 5 is near the front and rear ends of the stacker 4, the pawl 7 is moved. and the stacked banknotes 8 are separated from each other.

On the other hand, if the user forgets to take out the banknotes, the banknotes are collected. That is, if the user forgets to take out the banknotes and the banknotes 8 remain pushed out to the receiving slot 6 for a certain period of time, the fork 5 moves back and returns the banknotes 8 to their original position, and then the stacker 4 is removed. The fork 5 is lowered to the position shown by the two-dot chain line and moved forward again to collect the banknotes 8 into the collection box 9. Further, when the detector 10 detects that a plurality of banknotes 2 are simultaneously sent from the separating mechanism 3, the banknotes are stacked in the stacker 4 and then are not pushed out to the receiving port 6, but are placed in the collection box 9.
will be collected.

[Problem to be solved by the invention]

By the way, in the prior art described above, the stacker 4 is arranged horizontally and the banknotes 8 are sent out from the short side to the receiving port 6, so the depth dimension of the stacker 4 is equal to the long side of the banknote. There is a problem in that the length is considerably longer than the side dimensions, making it impossible to make the entire mechanism more compact.

SUMMARY OF THE INVENTION In view of the problems of the prior art described above, an object of the present invention is to provide a banknote discharging and collecting mechanism that can be reliably made compact.

[Means to solve the problem]

In the present invention, the panel is swingably supported by a first fulcrum on a fixed part, has a closing part for opening and closing the receiving port, and a bottom plate forming part for the stacker, and has a cylindrical shape with the top and bottom open. a stacker supported by a second fulcrum so as to be swingable between a first position in which the bottom portion is closed by a closed portion of the panel and a second position in which the bottom portion is opened; and a drive for driving the panel and the stacker. and a collection box installed at a lower position at the bottom of the stacker at the second position, and the drive means, when discharging banknotes, rocks the panel about the first fulcrum together with the stacker at the first position. The upper part of the stacker is exposed to the outside of the receiving slot by moving the stacker to open the receiving slot, and when collecting banknotes, the stacker is swung from the first position to the second position about the second fulcrum to open the stacker. It is configured to collect banknotes in a collection box.

[Effect]

First, when discharging banknotes, when a desired number of banknotes is fed into the stacker 4, the driving means swings the panel about the first fulcrum together with the stacker at the first position to open the receiving slot, and opens the receiving slot at the top of the stacker. Since the banknotes are exposed outside the receiving slot, the user can receive the banknotes fed into the stacker.

On the other hand, when collecting banknotes, when the driving means swings the stacker from the first position to the second position about the second fulcrum, the bottom of the stacker is released from the bottom plate forming part of the panel. The banknotes inside can be collected in the collection box.

In the present invention, as described above, since the stacker and the panel are configured to swing by the driving means, it is not necessary to make the depth of the stacker larger than the dimension of the long side of the banknote. The depth dimension of the entire mechanism can be shortened.

〔Example〕

Next, one embodiment of the present invention will be described with reference to FIGS. 2 to 4. Figure 2 a, b, c and Figure 3 a,
b and c show an embodiment in which the banknote discharging and collecting mechanism according to the present invention is applied to an automatic cash dispenser, and in the figures, the same parts as in the conventional example are given the same reference numerals.

The banknote discharging and collecting mechanism of the embodiment is roughly divided into, as shown in FIG. ing.

The receiving port 6 is opened in the casing 15 of the automated teller machine so as to communicate between the inside and the outside.
The panel 11 is swingably supported on the frame of the housing 15 by a first fulcrum 12, and in its normal state, the receiving opening 6 is closed as shown in FIG. By opening the receiving port 6 as shown in the figure and swinging it counterclockwise,
The receiving port 6 is closed as shown in FIG. Therefore, this panel 11 has a closed portion 11a shaped to open and close the receiving port 6, and has a bottom plate forming portion 11b for a stacker 4, which will be described later, at the bottom thereof. Note that the state in which the panel 11 closes the receiving port 6 is hereinafter referred to as the home position.

The stacker 4 has a cylindrical shape with its top and bottom open, and its upper part is swingably supported inside the panel 11 by a second fulcrum 13. In normal conditions, this stacker 4 has its bottom connected to the bottom plate forming portion of the panel 11 so as to be able to accommodate the banknotes fed thereto.
1b (Fig. 2a, b)
) and a second fulcrum 1 at a second position (see FIG. 2c) which is opened when the bottom part of the banknote is separated from the bottom forming part 11b when collecting banknotes.
It is designed to oscillate around 3.

Therefore, when the panel 11 opens the receiving slot 6 when discharging banknotes, the stacker 4 swings in the same manner as the panel 11 while remaining in the first position, and is exposed to the outside of the receiving slot 6. When the user is able to take out banknotes and when collecting banknotes, the stacker bottom plate forming portion 1 of the panel 11 swings clockwise about the second fulcrum 13 from the home position.
1b, the banknotes 8 in the stacker 4 descend into the collection box 9 from the bottom of the stacker and are collected.

Therefore, the collection box 9 is the second one of the stacker 4.
It is located at a lower position opposite to the bottom of the position.

Furthermore, the bill discharging and collecting mechanism of the embodiment includes a drive means for driving the panel 11 and the stacker 4.

The drive means, as shown in FIGS. 3b and c,
A shaft 14, three cams 14a to 14c respectively attached to the shaft 14, and a cam follower 1 pivotally connected to the frame 16 of the housing 15 by a pin 16b.
9a, a spring 20 that brings the cam follower 19a into contact with the cam surface of the cam 14c so that the drive lever 19 swings according to the operating diameter of the cam 14c, and a spring 20 that is attached to the stacker 4 and attached to the drive lever 19. Roller 4b that can move within the provided groove
, a first lock portion, and a second lock portion.

As shown in FIG. 3b, the first lock portion is
The middle part is pivotally attached to the frame 16 of the casing 15 by a pin (fulcrum) 16a, and one end is connected to the second fulcrum 1.
3, a spring 17b that urges one end of the upper hook 17 in the direction of engagement with the second fulcrum 13, and a spring 17b attached to the other end of the upper hook 17. , and a roller 17a disposed within the recessed part of the cam 14a.
One end engages with the second fulcrum 13 and the panel 11
When the rocking (opening and closing) of the cam 14a is stopped and the cam 14a rotates clockwise, the convex portion of the cam 14a touches the roller 17a.
The upper hook 1 resists the spring force of the spring 17b.
7 and the second fulcrum 13 is released, the lock to the panel 11 is released.

On the other hand, the second lock portion includes a lower hook 18 whose intermediate portion is pivotally attached to a protrusion 4a provided on the stacker 4 and the panel 11 by a pin 11c, and whose one end portion faces the protrusion 4a. It includes a spring 18b that biases one end toward the protrusion 4a, and a roller 18a that is attached to the other end of the lower hook 18 and disposed within the recessed part of the cam 14b. The stacker 4 is fixed to the panel 11 by blocking movement in the direction, and when the cam 14b rotates counterclockwise, the protrusion of the cam 14b hits the roller 18a, and the spring 18
One end of the lower hook 18 resists the spring force of b and the protrusion 4
When the stacker deviates from the position a, the rocking of the stacker to the second position is unlocked.

The drive means is such that when the banknote is ejected, the shaft 14 is in the second position.
When driven clockwise in figure b, the cam 14
a releases the lock of the first lock portion to the panel 11, and as the operating diameter of the cam 14c gradually increases, the cam 14c resists the spring force of the spring 20 and presses and swings the drive lever 19 via the cam follower 19a. At the same time, as the drive lever 19 moves, the roller 4b moves within the groove of the drive lever 19, causing both the stacker 4 and the panel 11 to swing around the first fulcrum 12, and the panel 11 to move. When the receiving port 6 is opened, the upper part of the stacker 4 is exposed to the outside of the receiving port 6. On the other hand, when the shaft 14 is driven counterclockwise in FIG. 2b when collecting banknotes, the cam 14b releases the lock on the stacker 4 of the second lock portion, and the working diameter of the cam 14c gradually becomes smaller. In this case, the stacker 4 moves from the first position to the first position about the second fulcrum 13.
The bottom of the stacker 4 faces the collection box 9, and the banknotes 8 in the stacker 4 are moved to the collection box 9.
It is designed to be lowered to the ground and recovered. In that case,
When collecting the banknotes 8, the banknotes 8 are
may be collected in the collection box 9.

In addition, when releasing, release the engagement of the upper hook 17,
If the lower hook 18 is kept engaged and the upper hook 17 is kept engaged during collection, and the lower hook 18 is disengaged, these disengagements can be made by swinging the panel 11 or the stacker 4. This must be done before starting, so until the roller 17a or 18a comes into contact with the convex part of the cam 14a or 14b,
It is desirable that the cam 14c has a constant working diameter.

Furthermore, special considerations have been made in the embodiments. In normal driving by a cam, the working diameter of the cam is kept constant near the stop position, but in the case of the device of this embodiment, when the open receiving port is forcibly closed, the cam follower 19a The force acting between the cam follower 19 and the cam 14c is in the direction connecting their centers.
a and the cam 14c cannot resist the force and are deformed. In this embodiment, as shown in FIG. 4, the operating radius of the cam 14c is not constant near the forward opening position;
The operating radius r ₂ below the point P is smaller than the operating radius r ₁ above the point P.

Therefore, the force PQ acting on the cam 14c from the receiving port 6→
is the size of the clockwise direction around point R.
Generates a torque of PQ.

When there is no external force, the cam 14c is driven by decelerating the motor, so compared to the friction torque of the cam drive system such as the motor and reduction gear, the force PQ→ is due only to the spring, so the torque is sufficient. The panel 11 and stacker 4 are small, and the panel 11 and stacker 4 are A in Fig. 3a.
It remains stuck in this state. When this frictional torque is small, a separate means for adding friction may be taken as necessary.

When an external force is applied, the magnitude of the force PQ→ increases, and when the torque becomes larger than the friction torque of the cam 14c drive system, the cam 14c rotates clockwise (Fig. 3c), causing the stacker 4 and panel to rotate. 11 begins to rotate in the direction of closing. This results in
Excessive force is not applied to each part, and deformation and destruction of the cam 14c and cam follower 19a are prevented.

In addition, the operating radius near the fully open position of the cam 14c
The difference between r ₁ and r ₂ is determined by taking into consideration the allowable angle of bill opening position accuracy and the magnitude of the frictional load of the cam drive system.

Next, the operation of the banknote discharging and collecting mechanism of the embodiment will be described.

First, when discharging banknotes, the banknotes 2 in the cassette 1 are sent out one by one by the separation mechanism 3, and when they are fed into the stacker 4 after passing between the rollers 30 and 30, the shaft 14 of the driving means is rotated as shown in FIG. 3b. The cam 14a releases the lock of the first lock portion to the panel 11, and the cam 14c
By pressing and swinging the drive lever 19 via the cam follower 19a, the panel 11 swings together with the stacker 4 to open the receiving port 6, as shown by the two-dot chain line A in FIG. It is exposed to the outside of the receiving port 6.

This makes it possible for the user to remove the banknotes 8 fed into the stacker 4, and after the banknotes are removed or after a certain period of time has passed, the shaft 14 is reversed and the stacker 4 and panel 11 return to the home position. Returning to , the upper hook 17 engages with the second fulcrum 13 by the spring force of the spring 17b.

When collecting banknotes, the shaft 14 of the driving means is driven counterclockwise in FIG. When the stacker 4 swings independently from the first position to the second position around the second fulcrum 13 by being pressed against the cam 14c, the bottom of the stacker 4 moves along the two-dot chain line B shown in FIG. When the banknote reaches the position , the banknote falls from the stacker 4 to the collection box 9 and enters the collection state.

Furthermore, after a certain period of time has elapsed, the shaft 14 is rotated in the opposite direction, the stacker 4 returns to the home position by the operation of the cam 14c, and the lower hook 18 is moved by the spring 18b.
It engages with the protrusion 4a by the force of. The stacker 4 or the stacker 4 and the panel 11 as shown in FIG.
If necessary, a stopper or the like may be provided in order to stop the swinging at the position indicated by the dotted chain line B or A.

In the embodiment, as described above, the stacker 4 and the panel 11 are configured to swing by the driving means, so the depth dimension of the stacker can be made larger than the dimension on the long side of the banknote, as in the conventional case. is no longer necessary, and the depth dimension of the entire mechanism can be reduced accordingly.

Further, the driving means includes the rotating shaft 14 and the cams 14a to 1.
4c, drive lever 19, spring 20, and roller 4
Since the locking device includes a locking device b, a first locking portion, and a second locking portion, it can be driven by one driving source, and the space can be saved accordingly.

In the present invention, the specific configurations of the panel 11, the stacker 4, the collection box 9, and the driving means are not limited to the illustrated example, and may be any structure as long as it has the intended function.

〔Effect of the invention〕

As described above, according to the present invention, it is no longer necessary to make the depth of the stacker larger than the length of the long side of the bill, and the depth of the entire mechanism can be reduced accordingly. .
