Field of the Invention The present invention relates to a door device for a ticket gate, and more particularly to a door drive mechanism capable of protecting a door driving mechanism when a predetermined force or more acts on the door. About things. [0004] Conventionally, this kind of automatic ticket gate door device, a connecting rod provided on the drive shaft of the reversible motor with speed reducer, it is opening and closing the door by the reciprocating motion of the connecting rod (e.g. Japanese Utility Model Application Laid-Open No. 52-9498). Then, when closing the passage, the brake is operated to fix the door. [0003] However, the above-mentioned conventional ticket gate door device operates the brake when closing the passage to fix the door and prevent the door from being opened further. , when a force greater than a predetermined the door is applied in this state, for example, when the passengers tried to pass attempt to force open the door, collided with the door in an attempt to pass on without knowing that it is invalid tickets In some cases, there is a possibility that the door mechanism acts as a lever and an excessive force, that is, an overload is applied to the drive mechanism, thereby damaging the drive mechanism. Accordingly, the present invention has been made to solve the above-mentioned drawback, and an object of the present invention is to rotate a door so as to open a passage when a predetermined force or more acts on the door. It is an object of the present invention to provide a door device for a ticket gate capable of protecting a drive mechanism. [0005] In order to achieve the above object, the apparatus of the present invention opens and closes a door by turning a rotary drive shaft rotated by a motor, and the door closes a passage. A door device for a ticket gate that fixes the door by positioning the door position by operating a brake by a positioning sensor provided on the rotary drive shaft when the door is closed, when the door closes a passage. A sensor for detecting movement, and rotation control means for rotating the door in the traveling direction of the passage when the sensor detects forced rotation, and then rotating the door again to a position for closing the passage. It is characterized by having been provided. In the above arrangement, when the door closes the passage, when a force exceeding a predetermined level is applied to the door and the rotary drive shaft is rotated, the sensor detects the forced rotation. When the sensor detects the forced rotation, the rotation control means rotates the door to open the passage, and then controls the door to close the passage again. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing a schematic configuration of an apparatus according to an embodiment of the present invention, FIG. 2 is a view taken along line AA, and FIG. 3 is a plan view showing a schematic configuration when a door closes a passage. The door 1 is rotatably supported at one end on a shaft 1a provided on the side of the passage P of the ticket gate main body a, and is provided to extend to the side opposite to the side of the passage P. Is connected via a connecting rod 4 to a rotation drive mechanism 3 provided in the ticket gate main body a. The rotary drive mechanism 3 includes a motor shaft 5 of a reversible motor (hereinafter referred to as a motor) M with a speed reducer with a brake mechanism.
And a bevel gear 7 that meshes with a bevel gear 6 provided on the motor shaft 5, and the rotation axis direction is located in the vertical direction.
That is, the rotary drive shaft 8 positioned parallel to the direction of the shaft 1a.
And an arm 9 provided at the upper end of the rotary drive shaft 8. One end of the connecting rod 4 (an end opposite to the end supported by the base 2) is provided at the tip of the arm 9. ) Is supported. The positioning member 10 is operated when the operation of the main body a is stopped. The positioning member 10 is formed integrally with the arm 9 below the arm 9 and is fixed to the rotary drive shaft 8. It is composed of a disk having a concave portion 11 formed as described above. The concave portion 11 is provided with an L-shaped leaf spring (engaging portion) 12. The strength of the leaf spring 12 is such that when an excessive force is applied to the door 1 from a direction opposite to the traveling direction of the passage P (see arrow E in FIG. 3), a roller 14 described later 12a
(See FIG. 3).
See dashed line). The locking member 13 is rotatably supported at a central portion and has a roller 14 at one end.
Is biased toward the positioning member 10 by the action of the spring 15, and the drive shaft 17 of the solenoid 16 is pivotally supported at the other end. As shown in FIG. , The solenoid 16 is activated and the roller 14
Are located away from the peripheral surface of the positioning member 10. A first sensor S1 comprising a light detecting element, a second sensor S1
The sensor S2 and the third sensor S3 are provided corresponding to the notched disks 18a, 18b, 18c fixed to the rotary drive shaft 8, respectively.
The rotation angle of the rotary drive shaft 8 can be detected by detecting the positions of the notches b and 18c. The detection signals detected by the sensors S1 to S3 are input to a controller C that controls the ticket gate main body a. This controller C
It is composed of a microcomputer and has a motor M,
It is configured so that the solenoid 16 and the like can be driven and controlled to control the ticket gate main body a as a whole. Next, the operation of this embodiment will be described with reference to the time charts of the sensors S1 to S3, the motor M and the brake shown in FIG. Now, as shown in FIG.
In order to close the passage P from the state in which it is stored in the ticket gate main body a and the passage P is opened, the rotary drive shaft 8 is rotated in the direction of arrow a. That is, the rotary drive shaft 8 is rotated via the motor shaft 5 rotated by the motor M and the pair of bevel gears 6 and 7, and this rotation causes the arm 9 to rotate in the direction of arrow A and the connecting rod 4 to move in the direction of arrow B. Moved to the right as shown. Due to the movement of the connecting rod 4, the door 1 turns around the shaft 1a in the direction indicated by the arrow C, and stops at the closing position substantially orthogonal to the direction of the passage P. When the door 1 is stopped at the position where the passage P is closed, the rotation angle of the rotary drive shaft 8 is detected by the first sensor S1 provided on the rotary drive shaft 8, and the motor is detected by the detection signal of the second sensor S2. The rotation of M is stopped, and at the same time, a brake (not shown) provided on the rotation shaft of the motor M is operated (see FIG. 1). Thereby, the passage P is closed,
Passage of the user from the traveling direction X of the passage P is prevented. When the door 1 closes the passage P, the passage P
To allow the passenger to pass from the traveling direction X, that is, the rotation from the state of the door 1 in FIG. 3 to the state of the door 1 indicated by the solid line in FIG. The rotation is performed in a manner opposite to the above. This rotation is detected by the OFF signal of the first sensor S1 (see FIG. 1). By the way, when the door 1 closes the passage P, the door 1 exerts a force Y over a predetermined amount from the traveling direction X of the passage P.
Is added (see FIG. 3), for example,
, The base 2 moves the connecting rod 4 in the direction of the arrow Y 'by the force. For this reason, the positioning member 10 rotates in the Y ″ direction opposite to the direction indicated by the arrow G, and this rotation is detected by the third sensor S3 provided on the rotary drive shaft 8. That is, the third sensor S3 is turned off. Accordingly, the controller C drives the motor M to rotate the door 1 in a direction opposite to the solid line position in Fig. 1 to overrun the passage P so as to open the passage P (see Fig. 1). Is reversely driven after 3 seconds by a timer (not shown) to rotate the door 1 to the position indicated by the solid line in FIG.
'). Then, the door 1 is again turned to the position shown in FIG. 3 ('in FIG. 1). As a result, the passenger colliding with the door 1 can be safely passed. When an excessive force is applied to the door 1 from the direction of the arrow E while the door 1 is closing the passage P, for example, the user forcibly pushes the door 1 open to advance the passage P. When an attempt is made to enter from a direction opposite to the direction X, the connecting rod 4 is moved in the direction of the arrow (left side) via the base 2 by the clutch 19 provided on the rotary drive shaft 8, and The movement moves the positioning member 10 in the direction of arrow G via the arm 9. The movement of the positioning member 10 causes the roller 14 to bend and allow the roller 14 to pass, thereby rotating the rotary drive shaft 8. Therefore, a situation in which an overload occurs in the rotation drive mechanism 3 is prevented. Once the positioning member 10 is rotated past the leaf spring 12, the rotation position of the rotary drive shaft 8 is detected by the first sensor S1 provided on the rotary drive shaft 8, and the door 1 is again moved to the position shown in FIG. Is set to the position indicated by. As described above, in the apparatus of this embodiment, the rotation of the rotary drive shaft 8 when the door 1 closes the passage and a predetermined force or more is applied to the door 1 is detected by the third sensor S3. Since the door 1 can be controlled to rotate so that the passenger can pass through, the overload generated in the rotary drive mechanism 3 can be prevented, and the inconvenience of damaging the rotary drive mechanism 3 is prevented. You. When the door 1 is forcibly turned, the door 1 is once turned to the position indicated by the solid line in FIG.
Is rotated to the position where it is closed, but the passage P may be directly closed after the forced rotation. According to the apparatus of the present invention, when the door closes the passage, the sensor detects the rotation of the rotary drive shaft when a force greater than a predetermined value is applied to the door, and the passenger passes through the sensor. Since the rotation of the door is controlled so that it can be performed, it is possible to prevent an overload from being generated on the rotary drive shaft and the like, and to prevent a disadvantage that the rotary drive mechanism is damaged.
