Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improvement in a card dispensing device that takes out stacked plate-shaped objects such as cards one by one, sends them out one by one, and holds the cards so that they protrude into a card dispensing slot.

BACKGROUND OF THE INVENTION Card dispensing devices are already known in which a card to which a value has been assigned in advance can be used to release a vending machine, an automatic lending device, etc. to sell products or use the device.

Generally, this type of card dispensing device has a structure in which the dispensed card is held so as to protrude from the card dispensing opening, and the customer is allowed to freely remove the card, in order to facilitate the handing over of the card to the customer. ing. Even when the card dispensing device performs an operation of dispensing a card, the card often gets jammed in the card conveyance path, and the card does not protrude from the dispensing opening, so that the card cannot be dispensed to a customer or the like.

Detects card jams that occur during card transport,
An "automatic ticket jam clearing device" which resolves card jams by reversing the conveyance direction of the card has been proposed in Japanese Patent Application Laid-Open No. 49-72000. In addition to the bill insertion detector and bill release detector that are essential for drive control, a bill passage detector must be installed separately to detect card jams, which increases manufacturing costs and makes the configuration itself difficult. There was a drawback that made it even more complicated.

Problems to be Solved by the Invention Therefore, it is an object of the present invention to make a paid card protrude from a card payout opening and hold it so that it can be extracted, and to do so without providing any special detection means.
To provide a card dispensing device that can automatically detect and clear a card jam that occurs during card transportation.

Means for Solving the Problems The card dispensing device of the present invention suctions and conveys one of the cards stacked on a hopper using a suction cup, and uses a suction cup provided at the tip of a lever that rotates by excitation of a solenoid. A hard conveying means that conveys the card to the card dispensing port by sandwiching the card with the roller rotated by the drive of a motor that operates together with the roller and the solenoid, and a position where the card is no longer detected when the card protrudes from the card dispensing port. a card dispensing detection switch provided near the card dispensing opening, which detects a card while the card dispensing detection switch detects a card; and a card dispensing detection switch provided near the card dispensing opening, which detects a card while the card dispensing detection switch detects a card, and a card dispensing detection switch provided in the vicinity of the card dispensing opening. A timer measures a predetermined time after the start of card dispensing, and when the card dispensing detection switch stops detecting a card before the timer measures a predetermined time after the start of card dispensing, the forward rotation of the motor is stopped, and the timer If the card removal detection switch detects a card even after the predetermined time has been counted, the motor is rotated in reverse until the card removal detection switch no longer detects a card, and then the motor is rotated forward to remove the card. The above object has been achieved by a configuration characterized in that it includes a control means for transporting the paper to the dispensing port.

In addition, the control means can send a failure signal if the card removal detection switch detects a card even if the card is reversely conveyed by reversing the motor for a predetermined period of time. After reverse conveyance, if the card is detected by the card dispensing detection switch even if the card is conveyed toward the card dispensing port by forward rotation of the motor for a predetermined period of time, the motor is reversed again to convey the card in reverse and send out a failure signal. You can do it like this.

Operation When the card conveying means is driven by the forward rotation of the motor, the timer is activated and the time after the start of card dispensing is counted.

When the card conveying means is driven, the card is sucked and conveyed from the hopper by a suction cup, then held between rollers, and conveyed toward the card dispensing port by the rotation of the rollers.When the leading edge of the card reaches the card dispensing detection switch, the card is When the payout detection switch detects a card and the leading edge of the card reaches the card removal detection switch, the card removal detection switch further detects the card.

If the card dispensing detection switch stops detecting the card before the above-mentioned timer measures a predetermined time after the start of card dispensing, that is, the rear end of the card detects the card dispensing before the predetermined time elapses after the start of card dispensing. When the card passes through the switch, the normal rotation of the motor is stopped by the control means, and the card is held so that it can be removed with the tip of the card protruding from the card dispensing opening, and when the card is removed, the card removal detection switch is activated. Card removal is detected when the card is no longer detected.

On the other hand, if the card dispensing detection switch is still detecting the card even after the timer has counted the predetermined time after the start of card dispensing, that is, even if the predetermined time has elapsed after the start of card dispensing, the rear end of the card does not reach the card dispensing point. If the card has not passed the detection switch, it means that the leading edge of the card has not yet protruded from the card dispensing slot and a card jam has occurred.The control means reverses the motor, and the card removal detection switch Until the card is no longer detected, that is, until the leading edge of the card being transported in the opposite direction passes the card removal detection switch, the card transport means is reversed and the card is transported in the opposite direction in order to clear the card jam. Then, the motor is rotated normally to transport the card to the card dispensing port.

In addition, if the card removal detection switch detects a card even after the motor is reversed for a predetermined period of time, it is determined that the card cannot be reversely transported by the card transporting means and the card jam cannot be cleared, and a fault signal is sent. If the card is sent out or if the card dispensing detection switch detects a card even if the motor is rotated forward for a predetermined period of time after the card is conveyed in the reverse direction by reversing the motor, the motor is reversed again and the card is conveyed in the reverse direction. It is also possible to send out a failure signal by causing the failure to occur.

When passing through parts 1 and 12, one baffle plate 11
is resisted by the force of spring 15 by the above card C,
It is moved to the left in FIG. 1 to facilitate the passage of the card C.

The operation of the present card dispensing device with the above configuration will be explained.

First, a brief description will be given of the process from when the suction cup 2 suctions the card C, the vertical moving plate 1 rises, and the card C is held between the rollers P ₁ and P ₂ .

When the card payout signal is input, motor _M1
rotates in the normal direction, the vertical moving plate 1 descends, and the suction cup 2 suctions the card C. When the card C is attracted, the reverse switch SW ₃ is turned ON, the vertical movement plate 1 is raised, and the solenoid switch SW ₂ and the carrier switch SW ₁ are turned on.
When turned on, the vertical moving plate 1 stops rising. The stop switch SW ₄ is for temporarily stopping the vertical moving plate 1. solenoid switch
When SW ₂ turns ON, solenoid SOL and motor M ₂
is activated, lever 9 rotates clockwise, and the roller
P ₁ and P ₂ hold card C between them. After this clamping, the lever 4 is rotated clockwise by the plate 3 and the air vent rod 6 is raised, so that the suction cup 2 no longer suctions the card, and the card C is transferred to the card dispensing port 14 by the rotation of the motor _M2 . It will be sent to.

Next, card conveyance, which is a feature of the present invention, will be explained with reference to FIGS. 2 and 3.

FIG. 2 is a transport control circuit diagram constituting the control means of the card dispensing device of this embodiment, in which I ₁ to I ₅ are inverters, D ₁ to D ₆ are differentiating circuits, FF ₁ to _{FF 3} are flip-flops, and A ₁ to _A3 are AND circuits, _G1 to _G4 are OR circuits, _T1 and _T2 are timer circuits, 20 is a solenoid drive circuit, and 21 is a motor drive circuit for motor _M2 .

First, normal feeding of the card C will be explained with reference to the timing diagram in FIG. 3A.

Vertical moving plate 1 rises and solenoid switch SW ₂
When ON, flip-flop FF ₁ is set through inverter I ₁ and differential circuit D ₁ , and the OR circuit is set.
Since the slide SOL is activated through G ₁ and an H level signal is input to the normal rotation terminal of the motor drive circuit 21, the motor M ₂ starts rotating in the normal direction, and the card C is moved between the rollers P ₁ and P ₂ , belt 13 and rollers P ₃ and P ₄ . The card C being conveyed pushes up the lever 16 of the card payout detection switch _SW5 , and the card payout detection switch _SW5
, then turn card removal detection switch SW ₆ on in the same way. Furthermore, card C
When the card is transported, the card dispensing detection switch SW ₅
The lever 16 no longer detects the card C, and the card payout detection switch SW ₅ is turned OFF.

In response to the OFF signal of the card dispensing detection switch _SW5 , the flip-flop _FF1 is reset through the differentiating circuit _D2 , the excitation of the solenoid SOL and the rotation of the motor _M2 are stopped, and a subtraction signal is output. Further, by stopping the motor _M2 , the card C stops with its tip protruding from the card dispensing port 14, and the card is held in a state where it can be extracted. Then, when card C is removed, card removal detection switch SW ₆ is turned OFF and timer T ₁ is turned off.
After the set predetermined time has elapsed, it is turned off and returns to the initial state, and the card dispensing device enters a standby state waiting for the next card dispensing.

Furthermore, by setting flip-flop FF ₁ ,
The H level output from the OR gate _G1 also sets a timer _T1 that measures a predetermined time after the start of card dispensing, but in the above-mentioned normal conveyance state, before the timer _T1 measures the predetermined time. Since the card payout detection switch _SW5 is turned OFF and the payout is completed, the operation of the timer _T1 has no effect on the actual processing.

The above is the conveyance operation in a normal case.Next, when the card C is conveyed, the card dispensing detection switch _SW5 is turned on, and even if the predetermined time set in the tie _T1 is counted, the card Payout detection switch
If SW ₅ does not turn OFF, that is, if the card C gets jammed during transportation and cannot be conveyed for some reason, and card dispensing detection switch SW ₅ continues to turn ON, reverse the motor M ₂ and turn card C once. The card is reversely conveyed and conveyed to the card dispensing port 14 again. The effect of this point will be explained with reference to the timing diagram in FIG. 3B.

As mentioned above in the normal transport operation, card C
is transported, and card dispensing detection switch _SW5 is activated.
If the card dispensing detection switch SW ₅ continues to be ON and the solenoid
SOL is energized and motor _M2 continues to rotate forward.
Next, when the set time of the timer _T1 has elapsed, the signal from the timer _T1 falls, this fall is differentiated by the differentiating circuit _D4 , and the differential pulse passes through the OR circuit _G2 and resets the flip-flop _FF1 .

Therefore, the H level signal from the OR circuit _G1 stops, the solenoid SOL is de-energized, and the motor _M2 stops rotating. On the other hand, the above differential circuit
The differential pulse of _D4 sets flip-flop _FF2 .

By setting the flip-flop _FF2 , an H level signal is input to the AND circuit _A1 , and
Card withdrawal detection switch SW ₅ and card removal detection switch SW ₆ are other inputs of AND circuit A ₁ .
The signal from the inverter I ₂ is also at H level, and
Since the signal from the flip-flop _FF3 is also at H level since it has not yet been set, an H level output is output from the AND circuit _A1 . The H level signal from the AND circuit _A1 is input to the reverse rotation terminal of the motor drive circuit, and the motor _M2 starts reverse rotation. Further, the H level signal from the AND circuit _A1 sets the timer _T2 .

Next, the card C is conveyed in the reverse direction due to the reverse rotation of the motor _M2 , so the card removal detection switch _SW6 is activated.
becomes OFF. The OFF signal of this switch SW ₆ is differentiated by the differentiating circuit D ₃ , and this differentiated pulse resets the flip-flop FF ₂ , so the AND circuit
The H level output from A ₁ disappears, and motor M ₂
The reversal of is stopped. On the other hand, the differential pulse from the differential circuit _D3 is passed through the inverter _I4 to the AND circuit.
A high level signal is input to _A2 , and the other input of the AND circuit _A2 is the card dispensing detection switch _SW5 ,
Since the signal from timer _T2 is also at H level,
AND circuit _A2 outputs an H level output and sets counter C to count value 1. This signal with a count value of 1 passes through the inverter I ₃ and the differential circuit D ₅ to set the flip-flop FF ₃ , so the OR circuit G ₁
A high level output is output from the solenoid SOL.
energizes and rotates motor _M2 in the forward direction. this motor
Due to forward rotation of M ₂ , card C is transferred to card dispensing port 1.
When the card C is conveyed again in the direction of 4 and is conveyed beyond the card payout detection switch _SW5 , the switch _SW5 is turned OFF. This OFF signal is differentiated by the differentiating circuit _D2 , and the differentiated pulse resets the flip-flop _FF3 via the OR circuit _{G3, so the output of the OR circuit G1 disappears} , excitation of the solenoid SOL, and rotation of the motor _M2. stops.
On the other hand, the differential pulse from the differential circuit _D2 resets the counter C and is output as a subtraction signal.

Note that the card C is ejected into the card dispensing port 14, and when the card C is removed, the card removal detection switch SW ₆ is turned OFF, and the timer T ₁ ,
After the set time has elapsed, _T2 is turned off and returns to the initial state, and the card dispensing device enters a standby state waiting for the next card dispensing.

Next, if the card dispensing detection switch SW ₅ does not turn OFF even after the card C is conveyed once in the reverse direction and forwardly conveyed again in the direction of the card dispensing port 14, the card C is conveyed in the reverse direction again and a failure signal is output. Take measures such as removing the equipment and stopping the operation of the equipment. in this regard,
This will be explained with reference to FIG. 3C.

The operation is the same as described above until the card C is conveyed backward once and then conveyed forward again. That is, the third
Up to *2 in Figure C are the same effects as above, but
*For point 2, card payout detection switch SW ₅ is the third
If something that is supposed to turn OFF does not turn OFF as shown in Figure B, the slide SOL will continue to be energized and the motor will
M ₂ continues to rotate forward. When the set time of the timer _T1 has elapsed, the differential circuit _D4 resets the flip-flop _FF3 through the OR circuit _G3 due to the fall of the signal from the timer _T1 , and the output of the OR circuit _G1 becomes L level. ,solenoid
Excitation of SOL and rotation of motor _M2 are stopped. On the other hand, the differential pulse generated by the falling edge of the timer _T1 signal from the differentiating circuit _D4 sets the flip-flop _FF2 . Therefore, all the inputs of the AND circuit _A1 become H level (the H level signals from the switches _SW5 and _SW6 are H level, and the inputs of the inverter _I2
From H, flip-flop FF ₃ has been reset.
level), so the output from AND circuit A ₁ is output and motor M ₂ is reversed. Meanwhile, the output of AND circuit _A1 sets timer _T2 again. Then, due to the reverse rotation of motor _M2 , card removal detection switch _SW6 no longer detects card C.
When turned OFF, the input of the AND circuit _A2 receives the H level signal from the timer _T2 and the card withdrawal detection switch _SW5 , and the differential pulse of the falling signal of the card removal detection switch _SW6 , which is input to _{the inverter I4.}
Since the inverted H level signal is input, the AND circuit _A2 outputs an output and sets the count value of the counter C to 2. The signal of the count value 2 of the counter C is outputted as a failure signal through the OR circuit _G4 , and processes such as failure indication and stopping of the device are performed. On the other hand, due to the fall of the card removal detection switch _SW6 , the differential pulse is activated by the flip-flop.
Since FF ₂ is reset and the switch SW ₆ goes to L level, and the output of flip-flop FF ₂ goes to L level, the output of AND circuit A ₁ also goes to L level, and the rotation of motor M ₂ stops.

Next, the card C is conveyed in the direction of the card dispensing port 14, and the card dispensing detection switch SW ₅ is turned on.
However, even if it is transported further, the above switch SW ₅ will not work.
If not turned off, motor _M2
is reversed and card C is transported in the reverse direction, but at this time, card removal detection switch SW ₆ is turned from ON to
The card should turn off, but for some reason it does not turn off and the card gets stuck on the conveyance path.

In other words, turn the switch at position *3 in Figure 3 (b).
If SW ₆ does not turn OFF when it should be turned OFF, switch SW ₆ still outputs an H level signal and the motor is turned off, as shown in Figure 3 D.
M ₂ continues to reverse. Then, when the set time of timer T ₂ has elapsed, the output of timer T ₂ falls.
This falling edge is differentiated by the differentiating circuit _D6 , and this differentiated pulse is inputted to the AND circuit _A3 through the inverter _I5 , so that the AND circuit _A1 , which is the other input of the AND circuit _A3 , and the switch SW Since the signal from ₆ is at H level, AND circuit A ₃ outputs an H level output, and outputs a failure signal through OR circuit G ₄ to display the failure and stop the device.

In this case, assuming that a card has been paid out, the output from the AND circuit _A3 may be taken out as a subtraction signal.

As described above, in the card dispensing device of this embodiment, the card dispensing detection switch SW is used to detect card dispensing during the card conveyance process in order to perform drive control to make the conveyed card protrude and hold at the card dispensing opening. ₅ and a card removal detection switch SW ₆ that detects card removal, these two detection switches SW ₅ and SW ₆ also detect card jams during transportation, and if a card jam occurs, the automatic After the card is transported in the reverse direction, the card is transported forward again to be sent out to the card dispensing port.Furthermore, if the card is not paid out from the card dispensing port even after the above processing, this will be detected by each of the above switches and a malfunction will occur. We made it possible to output a signal to indicate a failure, stop the device, etc.
Card dispensing and fault recovery from card jamming are reliably performed, and card dispensing can be managed accurately.

Effects of the Invention According to the card dispensing device of the present invention, the card dispensing detection switch for holding the conveyed card so as to protrude into the card dispensing opening, and the card dispensing detection switch for detecting card withdrawal to detect card withdrawal. to detect a card jam during card transport, and if a card jam is detected, drive control of the card transport means according to the detection state of the card dispensing detection switch and card removal detection switch to clear the card jam. Therefore, there is no need to provide special detection means to detect and clear card jams.
To provide a card dispensing device with a simple configuration and at low cost, which can automatically eliminate card jams and perform smooth dispensing work.
