Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a card sending mechanism in a card issuing machine that issues prepaid cards.

[Prior Art] Conventionally, magnetic cards used in automatic ticket vending machines and the like are sold after a card issuing machine magnetically writes amount information corresponding to the card price. This type of card issuing machine generally takes in magnetic cards one after another into a card transport path, transports them to a writing section, writes monetary information on the magnetic cards here, and then discharges them from a card ejection port. Cards with no amount information recorded are stacked and waiting on a card loading table that is movable up and down inside the card storage section, and the table is moved by a drive device every time the topmost magnetic card is sent out to the card transport path. I am trying to move it up and down intermittently.

[Problems to be Solved by the Invention] However, in such a conventional card dispensing mechanism, the card loading table is driven by a drive device such as a motor, so the weight of the loaded cards does not matter.
One drive device is required, and a rotation transmission mechanism, control circuit, wiring work, etc. are also required, which makes the structure complex and takes up space. Not only does the device itself become larger, but the manufacturing cost is also high. In addition, there were many problems, such as increased maintenance costs due to power consumption.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and its purpose is to raise and lower the card stacking table with spring force as the stack of stacked cards changes. It is an object of the present invention to provide a card sending mechanism that does not require a device, has low power consumption, and is simplified and inexpensive.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a card loading table which is arranged in a card storage NM so as to be freely raised and lowered and which is gradually raised as the number of cards loaded in the hN decreases; A stop roller is provided at the upper part of the card storage section, and the topmost loaded card comes into contact with the stop roller, and a delivery roller sends out the topmost loaded card to a card conveyance path, and is spring-mounted to the card loading table via an elastic member. By connecting this spring mounting member and the device fixing part with a constant force spring and a tension coil spring, the card loading table is moved upward by the combined force of these two springs, and the uppermost loaded card is moved up to the stop. It is designed to be pressed against the roller with a constant pressing force.

[Function] In the present invention, the constant force spring and the tension coil spring bias the card loading table upward with their combined force, and press the top loaded card against the stop roller with a constant pressing force regardless of the number of cards loaded. .

[Implementation fM] Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

The card delivery mechanism 1- is disposed within the card storage section 2 so as to be able to rise and fall freely. A card loading table 6 is provided on which a large number of magnetic cards 7 with unrecorded information are loaded.

The card storage section 2 forms a vertically long rectangular space, and the upper part communicates with the card storage section 4. Further, above the card storage section 2, there is a stop roller 11 to which the top loaded card of the magnetic cards 7 stacked and accumulated on the card stacking table 6 is pressed, and a stop roller 11 for taking the top loaded card 7 into the card holding section 4. A card take-in mechanism 12 that leads the card to the card transport path 3 is provided.

The stop roller 11 is arranged such that its roller shaft 11a is rotatably supported by a bracket 13, and restricts the lifting of the stacked cards 7. Note that the bracket 13 is fixed to a device fixing part.

The card receiving mechanism 12 has a shaft 1 horizontal to the device fixing part.
A movable block 16 is disposed so as to be rotatable in the vertical direction via a movable block 16, a delivery roller 17 and a belt driving roller 18 are disposed on both sides of the upper end of the movable block 16, and between these rollers 17 and 18. The movable block 1 is located at
A pair of tension rollers 19 rotatably provided at 6.
A, 19B and these rollers 17.18.19A, 19
A belt 20 stretched across B, a drive motor (not shown) that drives the belt driving roller 18, and a rotatable card lower holder that is pressed against the lower surface of the belt driving roller 18 are connected to a roller 21. , a solenoid 2 that rotates the movable block 16 counterclockwise in FIG. 2 and presses the delivery roller 17 against the top stacked card 7 when a card is taken in;
2, a return spring 23, etc., which gives the movable block 16 a return habit in the clockwise direction in FIG. The delivery roller 17 is located between the stop roller 11 and the card entrance section 4. The belt driving roller 1
8 is provided on the shaft 15, and the card lower holder and the roller 21 are arranged opposite to each other immediately after the card entrance portion 4 with the card conveyance path 3 in between.

The roller 21 of the card lower holder is rotatably provided on a rotary lever 24, and is pressed against the belt driving roller 18 by a spring 25. The tension roller 19
B can freely approach and leave the tension roller 19A,
A predetermined tension is applied to the belt 20 by being urged in the direction of the tension roller 19A by the spring 26.

The solenoid 22 is fixed to a fixed part of the device, and the tip of its operating rod 22A is connected to a U-shaped bracket 28 provided on the movable block 16, and a compression coil spring 29 causes the solenoid 22 to return in the direction. Habits are strengthened. One end of the compression coil spring 29 is pressed against the inner surface of one arm of the brague/soto 28, and the other end is pressed against a retaining ring 30 provided on the operating rod 22A.

The card loading table 6 has a card detection hole 31, and a bracket 33 is attached to the lower surface via an elastic member 32. A plurality of guide rollers 34 are rotatably attached to both left and right sides and the rear surface of the bracket 33, and these guide rollers 34 are connected to guides 35 that are erected on both sides and rear of the card storage section 2, respectively.
The card M mounting table 6 is supported in such a manner that it can be moved up and down. Furthermore, handles 36A and 36B are provided on one side and the back of the bracket 33, respectively, for lowering the table 6 when placing the magnetic card 7 on the card loading table 6. Furthermore, a spring attachment member 38 is attached to the front surface of the bracket 33 via a horizontal shaft 39.

The spring mounting member 38 is formed in a cylindrical shape, and has a constant force spring 4 on its circumferential surface that urges the card loading table 6 upward.
The lower end of 0 is connected and fixed.

The constant force spring 40 is made of a plate spring, and its upper end is fixed to a bracket 41 fixed to the device fixing part with a screw.

When the card loading table 6 moves upward, the lower end of the constant force spring 40 is wound around the spring mounting member 38. Further, the lower end of a tension coil spring 42 for card weight balance is locked to the three moeki shafts, and the upper end is locked 43 to another brassiere 1 provided in the device identification section.

The combined force of the tension coil spring 42 and the constant force spring 40 moves the card loading table 6 upwardly against the sum of the total weight of the card loading table 6 and the weight of the loaded cards 7, and moves the card loading table 6 upwardly. 7 is set so as to be always pressed against the lower surface of the stop roller 11 with a constant pressing force.

FIG. 4 is a diagram showing the spring characteristics of the constant force spring 40 and the tension coil spring 42. The spring force (B) of the constant force spring 40 is constant regardless of the number of magnetic cards 7 loaded. As for the spring characteristics of the tension coil spring 42, the tensile load and elongation are proportional. The weight of each magnetic card 7 is constant.

Therefore, since it is only necessary to select a spring that satisfies the equation of card weight/card thickness-spring constant, it is easy to match the spring constant to the weight of the magnetic card 7.

For the above reason, the weight of the number of loaded cards and the spring force of the tension coil spring 42 are canceled out (shaded area), and the spring force of the tension coil spring 42 in the attached state A> and the spring force of the constant force spring 40 ( The combined force (A+B) with B) is the best Fi6
This becomes the pressing force of the loading card 7 against the stop roller 11,
As shown in FIG. 4, this pressing force becomes a constant spring force regardless of the number of cards loaded.

In the card feeding mechanism 1 having such a configuration, when loading the magnetic cards 7 onto the card loading table 6, the handle 36A (or 36B) is manually pressed against the combined force of the constant force spring 40 and the tension coil spring 42. and push down to place a predetermined number of magnetic cards 7. After placing the handle 36A
(or 36B), the card loading table 6 is moved upward by the combined force of the constant force spring 40 and the tension coil spring 42, and the uppermost loaded card 7 is pressed against the stop roller 11 with a constant pressing force. . Note that when the uppermost stacked card 7 comes into contact with the stop roller 11 as the card stacking table 6 moves upward, the impact at this time is absorbed by the elastic member 32.

FIGS. 5(a) and 5(b) are diagrams for explaining the taking-in operation of the magnetic card 7. When the taking-in operation is started, the solenoid 22 is energized and excited, and the operating rod 22A is moved by the spring 2.
Protrude forward against 9. Then, the movable roller 16 is rotated counterclockwise against the spring 23 as shown in FIG. , rotation from a motor (not shown) drives the belt driving roller 18 and the belt 20.
The northernmost loading card 7
is taken in by frictional force and sent into the card entrance section 4.

Then, this magnetic card 7 is taken into the card conveyance path 3 by the belt driving pulley 18 and the card lower holder by the roller 21. When the sensor 46 detects this card, the detection signal is sent to the control section and the solenoid 22 Stop the power supply to. Therefore, the operating rod 22 of the solenoid 22
A moves back and returns due to the force of the spring 29, and the movable block 1
Release the pressed state of 6. For this reason, the movable block 16
Due to the force of the spring 23, the feed roller 17 is rotated back clockwise as shown in FIG.
m. On the other hand, since the belt driving pulley 18 rotates while holding the magnetic card 7 housed in the card lower holder together with the roller 21, the card can be securely housed.

By controlling the above-mentioned operations so that they are restarted after a certain period of time, it is possible to reliably send out the stacked cards 7 one by one. As a control method, it is preferable to have the control unit record a predetermined time in advance using software, or to provide a separate sensor and restart the operation when detected by that sensor. [Effects of the Invention] As stated above, Since the card feeding mechanism according to the present invention is configured to move the card loading table up and down using a spring, it does not require a drive device for raising and lowering the card loading table, has a simple structure, and can be made inexpensive and compact. At the same time, it is possible to provide a low-power-consuming card feeding mechanism.Also, regardless of the number of loaded cards, the top loaded card is pressed against the stop roller with a constant pressing force, so that the loading speed is reduced. Loaded cards can be sent out reliably without variations in friction over time.
