Description

[Detailed Description of the Invention] [Summary] A rotary impeller that rotates in conjunction with the opening and closing of the door, which is a control system for an opening/closing door such as a shutter of a cash entry/exit section of an automatic transaction device used in financial institutions, etc. By providing a detection means for detecting the rotational speed of the rotary impeller, it is possible to prevent a user's hand from being caught in a closing door or the apparatus to be stopped.

The present invention relates to a shutter control system for a cash entrance of an automatic transaction device of a financial institution, and more particularly to an opening/closing door control system that can prevent users from getting their hands caught and getting injured. .

In recent years, financial institutions, etc. have introduced automatic cash dispensing machines (A
uton+atic Teller Machine:
Automated transaction devices such as ATMs (hereinafter referred to as ATMs) are widely used,
Payout.

Transactions such as deposits and transfers are carried out.

For example, some ATMs are equipped with shutters on the cash slots and cash withdrawal slots during transactions, and when users insert their hands in and out of cash, it is desirable to have a simple method that prevents them from getting their hands caught in the shutters and getting injured. It is rare.

[Conventional technology]

Figure 4 is a front view of the ATM, with a card insertion row, a bankbook insertion slot 2, and a bankbook insertion slot on the front of the machine. Cash slot 3. and a withdrawal port 4 are provided.

This cash slot 3. Shutters 5a and 5b provided at the withdrawal port 4 are provided to prevent tampering from the outside and to prevent rainwater from entering the device installed outdoors, and controls for these shutters 5a and 5b are not shown. This is a method of simply opening and closing by driving a motor, for example, when the customer opens and closes the shutters 5a and 5b while the shutters 5a and 5b are closing.
If any part of the machine is pressed or an object is caught in the machine, the machine will be stopped as a malfunction.

Although not shown, automatic transaction devices for export are equipped with large shutters that open and close the front of the device, including the operation surface, and in this case, hands and arms can fit into the space inside the shutter. A method of detection using photosensors provided on the left and right frames is used.

Furthermore, although not shown, when the body of a person getting on or off an elevator hits the door, the movable part of the end face of the door is pressed, and a built-in microswitch detects this and opens the door. ing.

[Problem that the invention seeks to solve]

According to the above-mentioned conventional method, customers may get their hands caught in the ATV shutters 5a and 5b and get injured, and the equipment will be shut down due to an abnormality, which not only degrades the service but also makes it difficult to manage the operation of the equipment. It's a hassle.

In addition, in the detection method using a photosensor in a device that uses a large shutter to open and close the front of the device, the distance between the light-emitting element and the light-receiving element of the photosensor is long, which can cause the photosensor to be out of focus and malfunction due to dirt, etc., resulting in injury to customers. This may cause the equipment to stop working. Furthermore, the detection method using microswitches for elevators and the like requires a movable part to be provided on the end face of the door, and there is also the problem that it takes a long time from detection to opening the door.

[Means for solving problems]

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

In the figure, 5 is an opening/closing door, 6 is a motor, 7 is a rotary impeller in which notches 8 are formed at equal radial intervals and rotates in conjunction with the opening and closing of the opening/closing door 1, and 9 is a rotation of the rotary impeller 7. This is a detection means for detecting a change in speed.

Therefore, the opening/closing drive of the motor 6 is controlled based on the detection signal of the detection means 9.

[Effect]

When the opening/closing door 5 starts closing at a predetermined speed by driving the motor 6, the rotary impeller 7 rotates in conjunction. For example, if a user's hand hits the closing door 5, the speed at which the door 5 closes is restricted and becomes slower. Then, the rotational speed of the rotary impeller 7 decreases and is detected by the detection means 9.

Based on this detection, the motor 6 is driven in the reverse direction to open/close the door 5.
will be held.

In this way, reliable detection can be performed, and the response speed is 2, that is,
The time from detection to opening the door can be shortened, preventing injuries to users, and since transactions can be continued without stopping the device, the operating rate of the device can be increased and service can be improved.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 2 to 4. FIG. 2 is a block diagram showing an embodiment of the present invention, and FIG. 3 is a time chart of FIG. 2. In FIG. 2, parts corresponding to those in FIG. 1 are shown surrounded by a dashed line. The same reference numerals indicate the same objects throughout the figures.

In FIG. 2, 5c is a shutter, 6a is a motor, and 10
15 indicates a sensor amplifier, and 15 indicates a motor drive circuit.

The rotary impeller 7a has notches 8a formed at equal radial intervals, and rotates in conjunction with the opening and closing of the opening/closing door 1.

The photo sensor 9a has a light emitting element 91 and a light receiving element 92 facing each other in close proximity, and a rotary impeller 7a that passes between them.
A cutout portion 8a is arranged, and a detection signal is output by detecting light blocking or light transmission through the cutout portion 8a.

The timer 11 is a time counter that counts the pitch of the notch 8a based on the detection signal from the photosensor 9a and sends a counted time value T to the comparator 13 each time.

The setting unit 12 is a memory in which a predetermined time T0 is set.

Each time the counting time value T is sent from the timer 11, the comparing unit 13 reads out the predetermined time T0 from the setting unit 12 and compares it with the counting time value T, and does not transmit a signal when Tt''To. At the time of To, a signal a is transmitted to the main control section 16.

The shutter opening/closing mechanism 14 is composed of a gear group that decelerates the rotation of the motor 6a and a rack that opens and closes the shutter 5c. let

The main control section 16 has a function of controlling each of the above sections, opening and closing the shutter 5c, and managing the detection time by the photosensor 9a.

Since it has such a configuration and function, its operation will be explained using the time chart shown in FIG. 3. First, when the motor 6a is driven and the shutter 50 starts closing at a predetermined speed, the rotary impeller 7a rotates in conjunction with the motor 6a. and photosensor 9
a counts the pitch of the notch 8a, and the counting time value T continues under normal conditions. Each time the counted time value T is counted, it is sent to the comparison section 13 and set in the setting section 1.
It is compared with the predetermined time T0 read from 2.

Normally, when the shutter 5c is operating without any trouble, the time interval of the detection signal of the photosensor 9a, that is, the time count value T, is kept substantially constant and equal to the predetermined time T0, If the number of rotations is 5 rpS and the number of notches 8a is 8, then Tr-25a+s.

If the customer puts his/her hand on the shutter 5c or if something gets caught under the shutter 5c, the time count value T1 becomes longer, Tr>To, and the signal a is transmitted from the comparator 13. .

Then, the main control section 16 immediately stops the motor 6a, and drives the motor 6a in the reverse direction to open the shutter 5c again.

In this way, the problem can be solved with a simple configuration and at low cost. That is, the light emitting element 9 of the photosensor 9a
1 and the light receiving element 92 are close, providing good sensitivity, and a dustproof cover can be attached to ensure reliable detection.
This can be done quickly to prevent the customer's hand from getting caught in the shutter 5c, and there is no need to stop the device (it can continue to operate).

Furthermore, if a slip clutch or the like is used in the drive system when the shutter 5c is closed, the pressure on the customer's hand can be further reduced and safety can be further improved.

In the above example, the shutters of the cash slot and the cash withdrawal slot of an ATM will be described, but the present invention can be generally applied to the case of a motor-driven opening/closing door.

〔Effect of the invention〕

As explained above, according to the present invention, (1) the operation of the opening/closing door can be detected and responded to reliably and quickly, and injuries to users can be prevented.

■There is no need to stop the equipment when a user's hand or other object hits a closing door, and management is easy and service can be improved.

■Easy configuration and low cost.

There is an effect.
