Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is suitable for applying to ticket issuing machines such as admission tickets, tickets, betting tickets, and lottery tickets (hereinafter referred to as tickets). Regarding the detection mechanism.

[Conventional technology]

Conventionally, in this type of issuing machine that issues tickets such as entrance tickets, tickets, betting tickets, lottery tickets, etc., raw ticket groups stored in the stock section, that is, predetermined printing, recording of magnetic information, etc. have not been performed. It is used by sending out the processed ticket group one by one by an appropriate sending mechanism and guiding it to the ticket transport path, and recording the date and letters by the printing means such as the thermal head, and the magnetic information by the magnetic head. It is available as a ticket and is provided to users. The ticket in the stock section is pressed and urged toward the ticket supply port by the pressing means, and the pressing force of the pressing means decreases as the tickets are sequentially sent out. Then, since the ticket cannot be sent out stably and reliably, the pressing means is gradually moved forward as the number of tickets decreases. Also, if the pressed state is kept, a large load will be applied when the tickets are sent, and a plurality of tickets may be stuck and sent.
In order to prevent this, the pressing force is temporarily released when the ticket is sent.

[Problems to be solved by the device]

By the way, it is necessary to detect the ticket pressing state by the pressing plate and the ticket pressing released state to control the ticket delivery. In that case, a pressure sensor is provided on the pressing plate as a pressing force detection mechanism, and the distortion of this sensor is electrically controlled. Although a method of converting the signal into a signal and detecting the signal can be considered, such a pressure sensor has a drawback that it is special and expensive.

In addition, a method is known in which the pressing plate is moved by a drive motor and the pressing force is detected by the motor current.
In this method, the force to push the ticket is estimated only by the change in the current, so it cannot be distinguished from the disturbance (the pressing mechanism including the pressing plate is inoperable by hitting other mechanisms or parts, or is rusted and heavy). There was a problem.

Therefore, the present invention solves the above problems,
It is an object of the present invention to provide a ticket pressing force detection mechanism which has a simple structure and is inexpensive, and which can reliably detect a ticket pressing state and a ticket pressing released state of a pressing plate.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention has a pressing plate that presses and urges a group of tickets stored in a stock unit arranged substantially vertically and in the thickness direction toward a ticket supply port side, and is rotatably arranged on the pressing plate. A rotating arm provided, a guide shaft extending in the front-back direction of the stock portion, slidably disposed on the guide shaft, one end of the rotating arm is rotatably connected, and a ticket A slider that moves backward when sending out and moves forward after sending out a ticket, a spring that biases the rotating arm in a direction in which the pressing plate presses the ticket group, and a rotation between the rotating arm and the pressing plate. First detecting means provided on each of the rotating arms with the center of rotation of the arm with respect to the pressing plate interposed therebetween, and operating when the slider is advanced to detect a ticket pressing state in which the pressing plate presses the ticket. , In which the pressing plate by actuating upon retraction of the slider is constituted by a second detecting means for detecting a ticket pressing release state for releasing the pressing of the ticket.

[Action]

In the present invention, when the slider moves forward after sending out the ticket, the rotating arm presses the pressing plate against the ticket group by the force of the spring, and at this time, the first detecting means operates to detect the ticket pressing state. On the other hand, when the slider retreats when the ticket is sent out, the rotating arm also retreats to separate the pressing plate from the ticket group, and at this time, the second detecting means operates to detect the ticket pressing release state.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

FIG. 1 is a structural view of a ticket pressing force detection mechanism according to an embodiment of the present invention in a released state, and FIG. 2 is a main part configuration section showing the pressed state of the detection mechanism. In these figures, 1 is a stock section for storing a large number of unprocessed tickets 2 arranged substantially vertically and in the thickness direction thereof, and 3 is a stock section 1
The ticket transport path, which is provided above, is the stock section 1
A push-up plate that pushes up the tickets 2 stored therein one by one by a ticket sending signal and guides them to the ticket conveying path 3. The push-up plate 4 is arranged in the ticket supply port 5 of the stock section 1 so as to be vertically movable, The lower end of the inner side surface is integrally provided with a protrusion 6 having a protrusion dimension D that is substantially equal to or smaller than the thickness of one ticket, and the earliest ticket is provided on this protrusion 6.
2a is placed. On the other hand, a rack 7 and a pinion 8 as a mechanism for moving the push-up plate 4 up and down when sending out the ticket 2 are arranged at the lower part of one side surface of the push-up plate 4, and the rotation of the drive motor 9 is decelerated and transmitted to the pinion 8. Is configured to. In this case, the mechanism for moving the push-up plate 4 up and down is not limited to the rack 7 and the pinion 8, and a cam, a link mechanism or the like can be used.

In the vicinity of the upper portion of the ticket supply port 5, a thermal head 10 and a platen roller 11 for performing thermal recording of predetermined characters, symbols, dates, etc. on the ticket 2 are arranged to face each other across the ticket transport path 3. The ink tape 12 is inserted between them. The platen roller 11 is movable in directions toward and away from the thermal head 10 (directions of arrows A and B), is rotated in a ticket conveying direction (direction of arrow C) by a drive motor (not shown), and the ticket 2 is pushed up. When the upper end is pushed between the thermal head 10 and the platen roller 11 by being pushed up by a predetermined amount by the thermal head 10,
The ink jet tape 12 and the ink tape 12 are pressed against the thermal head 10 when the inserted ticket 2 starts to be conveyed. Then, when the ticket 2 is taken into the transport path 3 by the platen roller 11, the thermal recording is performed by the thermal head 10 as described above, and the magnetic head 14 provided at the subsequent stage of the transport path 3 is performed.
Thus, predetermined magnetic information is recorded.

The ink tape 12 is wound around a payout shaft 15 arranged in front of the push-up plate 4, and the payout end is guided upward through a tension roller 16 so as to pass between the thermal head 10 and the platen roller 11. It passes through the guide roller 17 and is wound around the winding shaft 18.

Now, inside the stock section 1, a group of tickets stored in the stock section 1 is intermittently urged toward the ticket supply port 5 side to push the first ticket 2a to the inner surface of the push-up plate 4. A ticket pressing mechanism 20 for attaching is provided. The ticket pressing mechanism 20 is provided below and parallel to the stock portion 1, so that the guide shaft 21 extending in the front-rear direction of the stock portion 1 and the guide shaft 21.
A slider 22 slidably disposed on the slider 22 and intermittently moved in the front-rear direction along the guide shaft 21 by a timing belt (not shown), and a lower end in the front-rear direction on the upper end of the slider 22 via a continuous pin 23. Is rotatably connected to
Also, the rotating arm 25, which has been given the habit of rotating in the front direction, that is, the direction of the ticket 2 by the spring 24, and the connecting portion 28.
a is connected to an intermediate portion of the rotating arm 25 so as to be rotatable in the vertical direction via a continuous pin 27, and is constituted by a pressing plate 28 which is pressed against the ticket group in the stock portion 1 by the spring force of the spring 24. The lower end of the rotating arm 25 is brought into contact with and engaged with the slider 22 so that the rotating arm 2
Stopper 2 for restricting further rotation of 5 in the counterclockwise direction
9 is projected integrally. Further, limit switches 30 and 31 as first and second detection means for detecting the ticket pressing state by the pressing plate 28 and the ticket pressing released state are provided on the pressing plate 2 at the middle portion and the upper end portion of the rotating arm 25.
8 are arranged so as to face each other.

FIG. 1 shows a state immediately before the start of the ticket 2 delivery operation by the push-up plate 4. In this state, the slider 22 retreats along the guide shaft 21 by a predetermined distance in order to cancel the pressed state by the pressing plate 28. The pressing plate 28 is slightly separated from the ticket 2. At this time, the rotating arm 25 is tilted by the force of the spring 24 to the side of the ticket 2 at the maximum angle, and the stopper 29 contacts the slider 22 to be held in the tilted state. Therefore, the upper end of the rotary arm 25 closely opposes the pressing plate 28, whereby the limit switch 31 provided on the upper end abuts against the pressing plate 28 to detect the pressed release state, and this detection signal Is sent to the control unit. On the other hand, the limit switch 3 installed below
0 does not operate because it is separated from the pressing plate 28.

Next, when the pressing plate 4 pushes up the first ticket 2a and returns to the lower position, the slider 22 moves forward so as to press the ticket 2 in the stock section 1 against the pushing plate 4, and the rotating arm 25 resists the spring 24. Then, it is rotated clockwise and set and held substantially vertically as shown in FIG. In this state, the stopper 29 of the rotating arm 25 is separated from the slider 22, so that the rotating arm 25 is biased counterclockwise by the spring 24 and presses the pressing plate 28 against the ticket 2.
At this time, the lower limit switch 30 comes into contact with the pressing plate 28 and operates to detect the pressed state of the ticket. On the other hand, the upper limit switch 31 is separated from the pressing plate 28 and opened.

Thus, according to such a ticket pressing force detection mechanism,
The two limit switches 30 and 31 are turned on and off depending on the inclination angle of the rotating arm 25 as the slider 22 moves back and forth.
Since the FF operation is performed, it is possible to reliably detect the ticket pressing state by the pressing plate 28 and the ticket pressing released state. Moreover, the limit switches 30 and 31 are less expensive than the pressure sensor, and the pressing force by the motor current is used. In the case of the detection method, it is necessary to provide a motor current detection circuit, but this is not necessary in the present invention, and the configuration is simple.

Although the limit switches 30 and 31 are used as the first and second detecting means in the above embodiment, an optical switch may be used without being limited to these, and the detecting means may be a rotating arm. It is needless to say that the pressing plate 28 may be provided not only on the side of 25 but corresponding to the rotating arm 25.

[Effect of device]

As described above, according to the ticket pressing force detecting mechanism of the present invention, the rotating arm is tilted in the front-rear direction as the slider moves forward and backward, whereby the pressing plate is intermittently pressed against the ticket in the stock portion to rotate. Since the first and second detecting means provided between the moving arm and the pressing plate are turned on and off by the tilting of the rotating arm, the structure is simple and the ticket pressing state and the ticket pressing releasing state are ensured. In addition, an inexpensive limit switch or the like can be used as the detection means.
