Description

[Detailed Description of the Invention] Industrial field of application: The present invention relates to a card sending-out device for use in vending machines such as so-called cash voucher cards which are of a pre-payment type such as telephony cards.

Conventional technology and problems: Due to the rationalization of various industries, prepayment down payment cards have come to be useful. Examples include telephony cards and ticket purchase cards. Furthermore, due to the inconvenience of using small amount of money with the enforcement of consumption tax, there is a tendency that many voucher cards are adopted.

In order to meet such a situation, some of these devices automatically sell voucher cards. However, since these cards are usually formed of thin plastic sheets, there are various problems in ensuring that the cards can be taken out one by one.

In other words, this card is not always flat,
Since it is often warped to the left and right and the wall thickness is thin, when trying to take out one by one from the bottom of the stacked layers,
It gets caught at the edge of the exit and cannot be sent out. For that reason, a measure is taken so that the warp of the card is eliminated and a pressing force is applied from above so that the cards are pushed out one by one from the bottom. However, in this case, an excessive resistance is generated, the driving force is naturally large, and one card is horizontally fed. Therefore, the structure and processing of the feeding portion are required to be precise. This is because, conventionally, such a feeding mechanism unit has a method of supporting and sliding the card at least on both sides in the moving direction.

Means for Solving the Problem: The present invention solves the above-mentioned conventional problems and provides a card feeding device capable of reliably feeding cards one by one with a simple structure. With the goal.

That is, in the present invention, in an automatic card feeding device, an eccentric roller for card feeding is arranged on the center line in the lower part of the card receiving part, and the lower end of the card receiving part of the card receiving part is on the center line. The receiving plate, which is in contact with the central portion of the front end and has an inclined surface on the inner side, can limit the feeding gap for one card between the lower end and the peripheral surface of the feeding roller arranged immediately below. The eccentric roller is arranged so that it can be adjusted up and down, and the power is transmitted from the feeding roller shaft by a driven belt. , Solenoid that operates by receiving a card sending signal between the pulley on the driving side feeding roller shaft driven by the belt and the pulley on the driven side feeding roller shaft Arranged class Tutsi pulley in contact with said both pulleys through a lever Te, the solenoid is in a configuration in which operation by a sensor for detecting the card edge was in conjunction to release delivered.

Function: In the present invention having such a configuration, the drive motor is activated and the solenoid is excited by the take-out command signal.
At the same time when the motor is started, the clutch pulley contacts the pulley of the feed roller shaft and the pulley of the feed roller shaft via the lever by the solenoid to transmit power, and the eccentric roller is driven. Due to the eccentricity of the eccentric roller, the stacked cards are lifted by the amount of eccentricity, thereby increasing the contact pressure between the card and the roller surface and positively moving the lowest card in the feeding direction. At the lower end of the card feeding side of the card storage part, the lower end of the receiving plate has an inwardly inclined surface to regulate the card exit gap in a centerline shape. Sent out. The delivered card is sandwiched between the upper and lower sides by a pair of delivery rollers and is positively delivered to the card take-out section. In addition, when one card has been sent out, the sensor detects the movement of its end,
By releasing the excitation of the solenoid and moving the lever, the power transmission action of the clutch roller is released.

The card is always supported on the center line of the card by a roller while it is being taken out from the accommodation part, and is sent out from the exit gap set so as to descend toward the exit. Therefore, even if it is warped in either the front-rear direction or the left-right direction, it is possible to reliably deliver the sheets one by one without causing clogging at the exit portion. Further, the card feeding power is fed one by one by an extremely simple clutch mechanism, so that there is no structural limitation.

Embodiment: Hereinafter, one embodiment of the present invention will be described with reference to the drawings.
It is as follows.

FIG. 1 is a vertical cross-sectional view of the device of the present invention, in which a card accommodating portion 15 is placed on a table 11 of a main body frame 10, and an eccentricity is provided at a lower position of the card accommodating portion 15. roller
A part of the peripheral surface of the card 21 is arranged above the surface of the table 11, and a feeding roller 22 is provided below the partition plate 12 on the card feeding side of the card storage portion 15 and a feeding roller 22 is also provided. From the position, the delivery rollers 23 are respectively placed at positions apart from each other by an appropriate dimension in the card delivery direction.
It is arranged so as to project above the surface. Eccentric roller
The eccentricity of 21 is about 2 mm in this embodiment. Each of these rollers 21, 22, 23 is mounted on each side plate 13, 13 of the main body frame 10 with its both ends bearing-supported so as to match the center line of the handling card A. It is fixedly arranged in the middle part of the ‘ Furthermore, each of these rollers 21, 22, 23 is
A drive motor 30 attached to one of the body frame side plates 13
The belt is wound around and driven. The motor output shaft 31 is projected to one outer side of the main body frame side plate 13, the pulley 32 on the output shaft 31 feeds the drive belt 34 around the pulley 33 on the roller shaft 23 ', and the drive roller 34 on the payout roller shaft 22'. A pulley 35 and a pulley 36 on the eccentric roller shaft 21 'are wound around a driven belt 37 to form a drive belt.
The 34 and the driven belt 37 are designed so that power is not transmitted in series.

As shown in FIG. 2, the drive belt 34 and the driven belt 37 are provided with a clutch pulley 45, one end of which is attached to the base of a lever 44 supported by a pin 38, and the other end of the lever 44 is provided with a pull spring 43. Solenoid with attached body frame 10
By pulling up the iron core 41 by the 40, the pulley 33 and the pulley 35 are simultaneously brought into contact with each other via the belt, and the power is transmitted from the driving side to the driven side. Therefore, when the excitation of the solenoid 40 disappears, the lever 44 descends due to its own weight, and the clutch pulley 45 cuts off the contact with both pulleys and cuts off the transmission of power to the driven side. . The tension spring 43 is a clutch pulley.
It plays the role of increasing the contact force of 45. A photo sensor 50 (not limited to this) is attached to the lower side of the end of the table 11 to detect the rear end of the sent card A, so that the excitation of the solenoid 40 is released. Connected to.

As shown in FIGS. 1 to 3, the card storage portion 15 is
A required amount (for example, about 100 cards) of the cards A to be handled are received, and the front, rear, left and right are surrounded, and a receiving plate 16 is provided inside the partition plate 12 on the front side thereof as shown in FIG. Both sides of the card are cut downward, and the lower end is card A
It is designed to receive only the central portion of the and its lower end is provided with a downwardly inclined surface 17. Between the lower end of the receiving plate 16 and the peripheral surface of the feeding roller 22 protruding toward the table 11, a gap through which one card A can pass, that is, a feeding port 18 is formed. This feeding port 18 can be adjusted in the vertical direction by loosening the mounting bolt 19 of the receiving plate 16, and a pushing spring 19 'is provided between the top surface of the receiving plate 16 and the bent portion 12' at the top of the partition plate 12. With the interposition of, it is possible to easily set the lowering of the receiving plate.

The device of the present invention configured as described above is installed in the required position of the vending machine, and when the motor 30 receives a signal from the operation command unit, it is driven by the control unit for an appropriate time and stopped. Connect and use.

A required amount of cards A are accommodated in the card accommodating portion, and a holding plate (not shown) having an appropriate weight above the card A if necessary.
To prevent the card A from rising.

A command signal is given to the motor 30 (a signal confirming that the consumer has paid a predetermined amount is issued) The motor 30
Then, when the coil of the solenoid 40 is energized and excited, the iron core 41 is pulled up, and the clutch pulley 45 is driven by the clutch pulley 45 and the driven pulley 35 through the lever 44 connected to the iron core 41. And the belt are brought into contact with each other, and power is transmitted from the driving side to the driven side. When the eccentric roller 21 on the driven side is rotated to push up the stacked cards A in the card storage portion 15 by the eccentric portion of the eccentric roller 21, the lowest card is the eccentric roller 21.
It is moved in the forward direction by the rotational force of and is pushed along the inclined surface 17 near the lower end of the receiving plate 16, and at the same time, it is inclined forward and downward and moved to the delivery port 18 side. At this time, the lower end of the receiving plate 16 is in contact with the tip on the center line of the card, and the load of the stacked cards acts on the lowest card A, and the roller 21 is relatively wide on the center line. Since the lowest card A is positively given a feeding force, even if the tip of the lowest card A is inclined downward, even if it is warped upward or widthwise, the front support plate The card A is guided by the inner inclined surface 17 of the card 16 and guided to the feeding opening 18, and the eccentric roller 21 propels the card A
Is pushed out from the feeding opening 18 by about 1/3 of its length.
During this time, the feeding roller located below the feeding port 18
The forward force is positively applied by 22 and the feed roller
When the leading end of the card comes into contact with the 23 pairs, the center line of the card A is nipped by the 23 pairs of the sending rollers and sent to the card outlet (not shown) of the vending machine.

If the card A is sent out and its rear end is detected by the photo sensor 50 provided at the end of the table 11,
Due to that signal, the solenoid 40 coil is de-energized, and the excitation removes the force that lifted the lever 44. Since the contact is broken (shown by the chain line in FIG. 2), the driving force to the driven belt 37 is stopped and the rotation of the eccentric roller 21 is stopped. The eccentric roller 21 is rotated once by one command signal so that one card is fed out at a time except when a plurality of cards are purchased, and the eccentric roller 21 stands by until the next operation. The motor stops its rotation and waits after a set time has elapsed.

Therefore, when a plurality of cards are to be taken out successively, the above operation is continued by sending a command to the solenoid for the required number of taken out cards, and the cards are sequentially sent out.

It should be noted that the devices of the present invention may be arranged on a shared table so that they can operate independently when they are arranged in multiple rows.

Effect of the Invention: According to the present invention, even a card that is thin and has a warp itself can be reliably sent out one by one, and the power transmission structure is a minimum component and a reliable operation function. As a result, it is possible to provide a dispensing device for a cash voucher card, which requires a reliable operation, in a state with a simple structure that can withstand long-term use without failure.
