Abstract

PURPOSE:To sharply improve delivery efficiency by providing a means which switches a speed when delivery of a medium by means of a delivery roller is unsuccessful to make and performs delivery at a low speed. CONSTITUTION:The delivery motion of a medium 1 from a medium feed part 2 is performed through rotation of a delivery roller 3 by means of a rotation drive means 9, the result of the delivery is detected by means of a detecting means 13, and when the delivery is successful to make, the medium 1 is conveyed as it is. When the delivery is unsuccessful to make, the rotation speed of the delivery roller 3 by means of the rotation drive means 9 is switched to a given low speed by a speed switching means 14 to perform delivery again. In which case, a friction force between the delivery roller 3 and the medium 1 is increased to deliver the medium 1. As noted above, by switching a delivery speed depending upon the result of the delivery of the medium 1, delivery can be stabilized.

[Industrial application field]

The present invention relates to a medium feeding mechanism of a medium handling device such as a banknote passbook used in a financial institution, etc., and in particular, when feeding the medium is unsuccessful, the rotation of the feeding roller is switched to a predetermined low speed to feed the medium. The present invention relates to a medium feeding mechanism that allows for

Automatic transaction devices such as automatic deposit/payment machines that have been used in financial institutions in recent years.9 Banknote sorting devices.

Although certificate issuing devices and other devices are equipped with a feeding mechanism that feeds out media, feeding may become unstable due to variations in paper quality and environmental conditions. This is causing a decline in operational efficiency.

In particular, automatic transaction machines have begun to be operated unmanned on holidays, etc., and it is therefore necessary to avoid equipment failures as much as possible. Therefore, a method for stabilizing the feeding of the medium is desired.

[Conventional technology]

FIG. 5 shows an internal side view of the certificate issuing device, in which a medium supply unit 2 a + which accumulates certificates 1a and sets them all together is shown in FIG.
For example, a feeding roller 3a made of rubber + a pulse motor Ml that rotates the feeding roller 3a via a belt 4
, a conveyance path 5 equipped with a sensor amplifier roller R1, etc., which detects the dispensed certificate 1a. 6. Printer unit that performs necessary printing on the sent certificate 1a. and a delivery lower. The lower end of the accumulated certificates 1a is placed on the feed roller 3
It is in contact with a.

Further, in FIG. 6, reference numeral 8 indicates a timer including a setting section 80 in which a time T0 is set, 9a indicates a feeding control section, 10 indicates a conveyance control section, 11 indicates a sensor amplifier, and 12 indicates a main control section.

Since it has such a configuration, FIGS. 5, 6 and 7
The feeding operation will be explained with reference to the timing chart shown in the figure.

First, the transport control unit 10 receives a feed-out instruction signal from an external device (for example, a host computer) not shown.
is started and the feeding roller R1 etc. start rotating due to the rotation of the motor h, and at the same time, the feeding control section 9a is started and the pulse motor M1 is driven, and the certificate 1a is fed out by the rotational frictional force of the feeding roller 3a.

The timer 8 starts simultaneously with the start of driving the pulse motor M1. The dispensed certificate 1a is conveyed by the feed roller R1, and when the sensor S detects the certificate 1a within the set time T0, the detection signal is activated. 11, the old pulse motor is stopped, and the timer 8 is cleared.

If there is no detection by the sensor S until the timer 8 counts the set time T0, a time-over signal is sent to the feeding control unit 9a, the driving of the pulse motor i is stopped, feeding is interrupted, and feeding is controlled again. The ID section 9a drives the pulse motor L to perform re-feeding by the feeding roller 3a. If the re-feeding is not successful after a predetermined number of attempts, the feeding operation is stopped and a warning lamp, buzzer, etc. are used to notify the malfunction. In this way, the certificate 1a is fed out.

[Problem to be solved by the invention]

According to the conventional method described above, when feeding is unsuccessful, feeding is interrupted and then the feeding operation is performed again. In this case, if the medium such as a certificate is fed halfway, it is ensured that it is transported to the conveyance path. However, for media that are not fed out at all, the feeding process itself is simply a repetition that does not include any special elements, so the feeding effect cannot be repeated and the feeding becomes unstable.

There is a problem in that the equipment is stopped due to malfunction in feeding, resulting in a decrease in service and operational efficiency.

The cause of failure in feeding is that the frictional force between the medium and the feeding roller decreases due to fluctuations in the pressure applied to the medium, variations in paper quality, and the influence of environmental conditions, resulting in slipping, and it is necessary to prevent slipping.

SUMMARY OF THE INVENTION An object of the present invention is to provide a medium feeding device that can stably feed the medium accommodated in a medium supply section even if there are variations in paper quality.

[Means to solve the problem]

FIG. 1 is a block diagram of the principle of the present invention.

In the figure, 1 is a medium, 2 is a medium supply unit, 3 is a feeding roller, 9 is a rotational drive means, 13 is a detection means for detecting whether the medium 1 is fed out by the feeding roller 3, and 14 is feeding by the rotational drive means 9. This is speed switching means for switching the rotational speed of the roller 3.

Therefore, when the detection means 13 detects that the feeding of the medium 1 is unsuccessful, the speed switching means 14 switches the rotational speed of the feeding roller 3 by the rotary drive means 9 to a predetermined low speed and feeding is performed again. has been done.

That is, focusing on the fact that the frictional force between the feeding roller 3 and the medium 1 is different when the rotational speed of the feeding roller 3 is fast and slow, and based on the fact that the frictional force increases when the feeding speed is slowed down, it is assumed that normal feeding will fail. If successful, slow down the rotation speed and try again.

[Effect]

The rotation driving means 9 rotates the feeding roller 3 to feed out the medium 1 from the medium supply section 2, and the detection means 1
3 detects whether the feeding is successful or not, and if it is successful, the medium 1 is conveyed as it is; if it is not successful, the speed switching means 14 changes the rotational speed of the feeding roller 3 by the rotary drive means 9 to a predetermined low speed. Switch and try feeding again. Then, the frictional force between the feeding roller 3 and the medium 1 increases (as a result, the medium 1 is fed out).

In this way, by switching the feeding speed depending on the success or failure of feeding the medium 1, feeding can be stabilized, so it is possible to avoid stopping the device.
Customer service and operational efficiency can be improved.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 2 to 4. Components in FIG. 2 that correspond to those in FIG. 1 are indicated by dashed lines. The same reference numerals indicate the same objects throughout the figures.

FIG. 2 shows a block diagram of the certificate issuing device, and in the figure, the timer 8a includes a setting section 80 in which a set time T0 is set, a setting section 81 in which a set time T is set, and a feeding control section. When feeding out at a normal feeding speed is commanded from 9b, counting is performed until set time T0, and when feeding out at a slow feeding speed is commanded, counting is performed until set time T1.

During normal feeding, the feeding control section 9b instructs the rotational speed switching section 14a to rotate the feeding roller 3a at the normal speed, and upon receiving a timeout signal of the set time T0, the feeding control section 9b instructs the rotational speed switching section 17a to rotate the feeding roller 3a at the normal speed. rotation at a speed slower than the normal speed (e.g. 2
) to switch.

The rotational speed switching unit 14a selects the pulse motor 4. When receiving a rotational speed switching command, the rotational speed of the pulse motor M1 is switched to either the normal speed or a speed slower than the normal speed. Further, 12a indicates a main control section.

Since it has such a configuration and function, the operation will be explained with reference to the flowchart in FIG. 3 and the timing chart in FIG. 4.

■First, in response to a feed-out instruction, the conveyance control unit 10 is activated and the feed roller R1 starts rotating due to the rotation of the motor, and at the same time, the feed-out control unit 9b is activated and the rotation speed switching unit 1
4a to feed out at the normal speed, the pulse motor M8 is driven, and the certificate 1 is rotated by the rotation of the feeding roller 3a.
The feeding of a is started.

(2) The timer 88 starts at the same time as the pulse motor h starts driving.

■The fed out certificate 1a is conveyed by the feed roller R1, and when the sensor S detects the medium 1a within the set time T0 (at the time of successful feeding indicated by the dotted line in FIG. 4), a detection signal is sent to the feeding control section 9b. The pulse motor gate is stopped and the timer 88 is cleared.

(2) If there is no detection by the sensor S until the timer 8a counts the set time T0, a time-over signal is sent to the feed control 1 section 9b.

■Feeding system? The 11 part 9b issues a command to stop driving the pulse motor cap, and also commands the rotation speed switching part 13a to rotate at a low speed.

(2) Then, the feeding by the feeding roller 3a is stopped.

■The old nose motor is driven again by low speed rotation. The timer 8a is started at the same time as the pulse motor N starts driving.

■The dispensed certificate 1a is conveyed by the feed roller R1, and when the sensor S detects the certificate 1a within the set time T1 (at the time of successful dispensing indicated by the solid line in FIG. 4), a detection signal is sent to the dispensing control section 9b. The pulse motor gate is stopped and the timer 88 is cleared.

(2) If there is no detection by the sensor S until the timer 88 counts the set time T1, a time-over signal is sent to the feeding control section 9b.

[Phase] The feeding operation is stopped by a command from the feeding control section 9b, and the main control section 12a suspends the feeding of the device, and notifies the feeding malfunction using a notification lamp, a buzzer, etc. (not shown).

In this way, when feeding is unsuccessful at the normal rotational speed, by slowing down the rotational speed and feeding, stable feeding can be achieved and equipment stoppages can be prevented, improving customer service and equipment operating efficiency. can be increased.

In the above example, when feeding at low speed is unsuccessful,
It is also possible to repeat the process multiple times.

Further, in the above example, the case where the switching speed is in two stages has been described, but it is also possible to switch the speed in three or more stages.Although the speed switching has been described as electrically switching, it may also be mechanically switching.

Furthermore, although the case of a certificate issuing device has been described, the present invention can also be applied to a case of a banknote handling device, a banknote handling device, etc. that handles media such as a banknote and a bankbook.

〔Effect of the invention〕

As explained above, according to the present invention, when the feeding roller fails to feed the medium, by switching the speed and feeding the medium at a low speed, the success rate of feeding can be significantly increased, stable feeding can be achieved, and the device can be smoothly fed. Since suspensions can be prevented, service to customers and operating efficiency of the equipment can be improved.
