JP 2010-196428 A

  The opening and closing of each flap in a conventional security gate is driven by an individual motor. For this reason, in the case of a security gate in which there are passages on both sides of the gate body and flaps are provided on opposite sides, motors provided on the opposing flaps are mounted close to each other. Therefore, the shape of the gate main body is bulky to accommodate a plurality of motors for operating the flaps on both sides. In addition, there is a problem in that the driving unit including the motor is provided close to the driving unit, and the configuration is complicated.

  As a result, in the conventional security gate, space saving cannot be achieved, which has been an obstacle to making the security gate itself a compact design. Further, there has been a problem that the manufacturing cost of the security gate cannot be reduced and the occurrence of a failure cannot be suppressed.

  An object of the present invention is to solve the above-mentioned problem, and to provide a security gate and a security gate opening / closing method for realizing space saving by making a mechanism of a driving unit for opening and closing a flap provided on both sides of a gate body more compact. To provide.

In order to achieve the above object, a security gate according to the present invention is a security gate including a plurality of flaps that open and close in both side passages, wherein the motor has a driving unit that rotates the flaps, The motor may be controlled to a closed position where passage of a passage is prohibited, or a motor shaft may be engaged with a rotation gear and separated from a reverse rotation gear to rotate in the rotation direction of the motor and controlled to an open position in the rotation direction. The shaft is engaged with the reverse rotation gear, and is separated from the rotation gear to control the shaft to the reverse rotation open position.

  According to the above configuration, by driving a plurality of flaps by one motor, a driving unit having a function of transmitting rotation of the motor to opening and closing of the flaps can be simplified, and a compact security gate can be realized. In addition, by making the mechanism of the drive unit of the security gate compact, the production cost of the security gate can be further reduced, and the occurrence of failure can be further suppressed. The mechanism for transmitting the rotation of the motor to the opening and closing of the flap is not limited to a transmission method combining a plurality of gears, but may be a transmission method using a timing belt.

  Further, in the security gate, it is preferable that the motor rotates only in a certain direction. Thus, by driving a plurality of flaps with one motor, the mechanism of the driving unit that opens and closes the flaps can have a more compact configuration. Further, a mechanism for changing the rotation direction of the motor is not required, and the security gate can be made compact and space-saving.

  In the security gate, the motor rotates the flap by a driving unit in which a plurality of gears are combined, and the driving unit rotates in the same direction as the rotation of the motor, and the driving unit prohibits the passage of the passage. It is preferable to control the opening position in the rotation direction to be allowed and the opening position in the reverse rotation direction to allow the passage of the passage by rotating in the opposite direction to the rotation of the motor. As described above, by the technique of combining a plurality of gears, a plurality of flaps can be freely opened and closed at a closed position, a rotationally open position, and a reverse rotationally open position only by rotating one motor in a fixed direction.

  Further, it is preferable that the security gate is constituted by a rotation gear in which the drive unit rotates the flap in the same direction as the rotation of the motor, and a reverse rotation gear in which the flap rotates in the direction opposite to the rotation of the motor. As described above, by forming the rotation direction gear and the reverse rotation direction gear by combining a plurality of gears, the flap can be freely opened and closed with a compact drive unit configuration.

  In addition, the security gate has a rotation gear and a reverse rotation gear connected to a solenoid via a connecting rod, and when the solenoid sets the flap to the closed position, the rotation gear and the reverse rotation gear are connected to the shaft of the motor. It is preferable to move it to a position away from it. Thereby, the rotation direction gear and the reverse rotation direction gear can be switched by the solenoid and the connecting rod, and the flap can be freely opened and closed by the configuration of the compact drive unit.

  Further, the security gate, the rotation gear and the reverse rotation gear are connected to a solenoid via a connecting rod, the solenoid, when the flap is installed in the rotation opening position or the reverse rotation opening position, Preferably, the shaft of the motor is moved to a position where only one of the rotation direction gear and the reverse rotation direction gear meshes. Thereby, the rotation direction gear and the reverse rotation direction gear can be switched by the solenoid and the connecting rod, and the flap can be freely opened and closed by the configuration of the compact drive unit.

  Further, the security gate is preferably such that when the flap is installed in the closed position, the rotation of the flap shaft is fixed by the brake. Thereby, unnecessary rotation of the flap can be suppressed when the flap is installed at the closed position.

To achieve the above object, security gating method according to the present invention, or a security gate opening and closing process of which includes a flap that opens and closes on both sides of the passage, to operate either of the flap, and the flap closed A step of receiving information on which of the position and the open position to operate, a step of connecting a predetermined drive unit to the motor based on the information, and a step of disconnecting the other drive units from the motor; and Moving the flap to a predetermined position.

  According to the above configuration, the step of connecting a predetermined drive unit to the motor and removing the other drive units from the motor is included, so that the drive unit having a function of transmitting the rotation of the motor to the opening and closing of the flap can be simplified and compact. Security gate can be realized. In addition, by making the mechanism of the drive unit of the security gate compact, the production cost of the security gate can be further reduced, and the occurrence of failure can be further suppressed.

  In addition, the security gate opening / closing method includes a step in which the driving unit includes a plurality of gears, and pushes and pulls a connecting rod to connect a gear to be connected to the motor to the motor, and removes other gears from the motor. Is preferred. Thereby, the step of connecting a predetermined drive unit to the motor and disconnecting the other drive units from the motor is realized by the connecting rod, and the drive unit having a function of transmitting the rotation of the motor to the opening and closing of the flap can be simplified and compact. Security gate can be realized.

(Configuration of security gate)
Hereinafter, one embodiment of a security gate 1 according to the present invention will be described in detail with reference to the drawings. FIG. 1 shows a schematic configuration of one embodiment of the security gate 1 in a cross-sectional view cut in a horizontal direction. FIG. 2 is a sectional view taken along the line AA of the security gate 1 shown in FIG. FIG. 3 is a block diagram showing a driving mechanism of the security gate 1 shown in FIG.

As shown in FIG. 1, the security gate 1 of the present embodiment includes a gate body 5, a right flap 2 a and a left flap 2 b provided above and below the gate body 5, and a driving mechanism for rotating the flaps 2 a and 2 b. in it, and a motor shaft 10, the right flap rotary gear _8a, 8b 1, 8b _2, the left flap rotation gear _{9 a, 9b 1, 9b 2} , flap rotary gear 13. In addition, in this specification, up, down, left, and right are defined by the direction toward each drawing.

  As shown in FIG. 2, the gate body 5 is surrounded by two side panels 26, and a motor 24 is installed inside the gate body 5, and the motor shaft 10 extends downward from the motor 24. Then, the motor shaft 10 penetrates a gear head 25 for adjusting the rotation speed of the motor 24 and is engaged with the right flap rotation gear 8 and the left flap rotation gear 9 provided on the lowermost layer of the security gate 1. In the present embodiment, the motor 24 rotates only in a predetermined direction to rotate the flaps 2a and 2b in the respective predetermined directions, but the motor 24 does not rotate in the reverse direction. This eliminates the need for a mechanism for controlling the rotation direction of the motor 24 in the gear head 25 in the forward or reverse direction.

As shown in FIG. 1, the motor 24 rotates the flap 2a by the right flap rotation gear 8, which is a driving unit in which a plurality of gears are combined. As for the right flap 2a, the rotation of the motor shaft 10 is transmitted to the flap rotation gear 13 via the right flap rotation gear 8. Since the flap rotating gear 13 is fixed to the right flap 2a, the right flap 2a is freely rotated. The right flap rotation gear 8 has two types of rotation transmission paths. One rotation transmission path is positive rotation direction gear 8a, the other rotation transmission path are opposite rotational direction the gear 8b ₁ and 8b _2. These rotation transmission paths serve as drive mechanisms for independently rotating the right flap 2a, as will be described later. As described later, the normal rotation direction gear _{8a, 9a, 8b 2, 9b} 2 is separated or contact with the motor shaft 10 by position 20a~20c drive mechanism, for purposes of explanation in FIG. 1, This shows a state where all the drive mechanism rotating gears 8a, 9a, 8b ₂ , 9b ₂ are in contact with the motor shaft 10.

Similarly, the motor 24 rotates the flap 2b by the left flap rotation gear 9, which is a driving unit in which a plurality of gears are combined. Regarding the left flap 2b, the rotation of the motor shaft 10 is transmitted to the flap rotation gear 14 via the left flap rotation gear 9. Since the flap rotation gear 14 is fixed to the left flap 2b, the left flap 2b is freely rotated. The left flap rotation gear 9 has two types of rotation transmission paths. One rotation transmission path is positive rotation direction gear 9a, the other rotation transmission path are opposite rotational direction the gear 9b ₁ and 9b _2. These rotation transmission paths serve as drive mechanisms for independently rotating the left flap 2b, as described later.

  As described above, in the present embodiment, the driving units 8 and 9 rotate the flaps 2a and 2b by a combination of a plurality of gears. However, the driving units 8 and 9 are not limited to this gear system, but may be a timing belt system or a sliding system. Is also good.

  The right flap 2a and the left flap 2b are independently rotated by the single motor 24 in the forward rotation direction R1 or the reverse rotation direction R2. The forward rotation direction R1 refers to a clockwise direction toward each drawing, and the reverse rotation direction R2 refers to a counterclockwise direction toward each drawing. The right flap 2a and the left flap 2b are located at three positions (see FIGS. 4 to 6) described later, that is, a closed position 21, a forward rotation direction opening position 22, and a reverse rotation direction opening position 23. The closed position 21 is a position where passage of the passages 3a and 3b shown in FIG. 1 is prohibited. Further, the forward rotation direction open position 22 is a position where the motor 3 rotates in the same direction as the rotation of the motor 24 to permit passage of the passages 3a and 3b. Further, the reverse rotation direction open position 23 is a position where the motor 3 rotates in the reverse direction to the rotation of the motor 24 to permit passage of the passages 3a and 3b.

  The position 20 of the driving mechanism for the flaps 2a and 2b will be described with reference to a block diagram shown in FIG. The position 20 of the drive mechanism of the present embodiment includes the control unit 11, the power unit 12, the right flap rotation gears (drive units) 8a and 8b, the left flap rotation gears (drive units) 9a and 9b, the right flap 2a, and the left flap. 2a.

The control unit 11 transmits commands to the driving units 8a and 8b, the driving units 9a and 9b, and the power unit 12, and controls the positions of the right flap 2a and the left flap 2b. Further, the control unit 11 issues a command to the motor 24 via the power unit 12 to control the number of rotations. Further, the control unit 11 determines which of the driving units 8a and 8b and the driving units 9a and 9b is to be operated. That is, it is determined whether the right flap 2a or the left flap 2b is to be rotated forward or backward, and the operation is performed so that one drive unit rotates and the other drive unit does not rotate.

(Drive mechanism)
FIGS. 4 to 6 show a drive mechanism for rotating the flap 2 by a combination of the drive units 8 and 9. In the present embodiment, the first position 20a, the second position 20b, and the third position 20c are set by moving the gear connecting rod 15 of the security gate 1. The position 20 of the drive mechanism of the present embodiment includes a drive unit 8 related to the rotary gear 8 for rotating the right flap 2a and a drive unit 9 related to the left rotary gear 9 for rotating the left flap 2b. 4 to 6, only the driving unit 8 is illustrated. The driving unit 9 is the same as the driving unit 8. In FIGS. 4 to 6, gears are described for rotating gears, and gears are not described for non-rotating gears so that the driving method of the gears can be easily understood.

Forward rotation gear 8a and the reverse rotational direction gear 8b ₂ is fixed to the gear coupling rod 15. 4 to 6, the solenoid 17 is provided with a reference sign P1 indicating leftward movement toward the drawing and reference signs P2 and P3 indicating rightward movement toward the drawing. It is connected. That is, if the gear connecting rod 15 is left movement P1, or rightward movement P 2, P3 Then, one of the positive rotation direction gear 8a or reverse rotational direction gear 8b ₂ is a positional relationship to engage the motor shaft 10 .

FIG. 4 shows the first position 20a of the security gate 1, in which the right flap 2a rotates in the reverse rotation direction R2 to be in the reverse rotation open position 23. When the solenoid 17 pushes the gear connecting rod 15 in the direction P1, the gear connecting rod 15 moves leftward as viewed in FIG. Then, the motor shaft 10, separated from the forward rotation direction gear 8a, engages the reverse rotation direction gear 8b _2. In this case, the motor shaft 10, the reverse rotation direction gear 8b _2, the reverse rotation direction gear 8b _1, and flap rotation gear 13 is continuously engaged. As a result, the motor shaft 10 is forward rotation R1 Then, the reverse rotation direction gear 8b ₂ and reverse rotation R2, the reverse rotation direction gear 8b ₁ is forward rotation R1. As a result, the flap rotation gear 13 rotates in the reverse direction R2. Thus, the flap 2a rotates from the closed position 21 in the reverse rotation direction R2 and moves to the reverse rotation direction open position 23.

FIG. 5 illustrates the second position 20 b of the security gate 1, in which the right flap 2 a is in a free state in the closed position 21. When the solenoid 17 pulls the gear connecting rod 15 from the position of FIG. 4 in the P2 direction, the gear coupling rod 15 moves to the right toward the FIG. Then, as shown in FIG. 6, the motor shaft 10 is engaged with the forward rotational direction gear 8a, separated from the reverse rotation direction gear 8b _2. In this case, the motor shaft 10, the forward rotation gear 8a, and the flap rotation gear 13 are continuously engaged. As a result, when the motor shaft 10 rotates in the forward direction R1, the forward rotation gear 8a rotates in the reverse direction R2. As a result, the flap rotation gear 13 rotates in the forward direction R1. Thereby, as shown in FIG. 5, the flap 2a rotates from the open position 23 in the reverse rotation direction indicated by the broken line in the forward rotation direction R1 and moves to the closed position 21. When the flap 2a is moved to the vicinity of the closed position 21, to separate the motor shaft 10 and both the forward rotation direction gear 8a and the reverse rotational direction gear 8b _2. As a result, the rotation of the motor shaft 10 is not transmitted to the flap rotation gear 13. As a result, the flap 2a moves in the normal rotation direction R1 from the reverse rotation direction open position 23, and stops at the closed position 21 with the electromagnetic 16 brake shown in FIG.

FIG. 6 shows the third position 20c of the security gate 1, in which the right flap 2a rotates in the forward rotation direction R1 to be in the forward rotation direction open position 22. When the solenoid 17 further pulls the gear connecting rod 15 in the direction P3, the gear connecting rod 15 moves rightward as viewed in FIG. Then, the motor shaft 10 is engaged with the forward rotational direction gear 8a, separated from the reverse rotation direction gear 8b _2. In this case, the motor shaft 10, the forward rotation gear 8a, and the flap rotation gear 13 are continuously engaged. As a result, when the motor shaft 10 rotates in the forward direction R1, the forward rotation gear 8a rotates in the reverse direction R2. As a result, the flap rotation gear 13 rotates in the forward direction R1. As a result, the flap 2a rotates from the closed position 21 in the forward rotation direction R1 and moves to the forward rotation direction open position 22.

(Function of electromagnetic brake)
As shown in FIG. 5, the flap 2a, the 2b is placed in the closed position 21, the motor shaft 10, the normal rotation direction gear 8a of the right flap rotating gear 8, and also in any direction of reverse rotation gear 8b ₂ Does not mesh. Therefore, the rotation of the motor shaft 10 is not transmitted . Then, only the reverse rotation direction gear 8b ₁ is in contact with the flap rotation gear 13. For this reason, the flap 2a is not completely fixed to the closed position 21 and may move left and right. Therefore, as shown in FIG. 2, an electromagnetic brake 18 is mounted on the rotating shaft 16 of the flaps 2a and 2b. The rotation of the flaps 2a and 2b in the closed position 21 is fixed by this braking function.

(Configuration of security gate opening and closing method)
FIG. 7 is a flowchart showing a schematic configuration of one embodiment of the method for opening and closing the security gate. In the present embodiment, a method of opening and closing the security gate 1 including the flaps 2a and 2b that open and close the passages 33a and 33b on both sides of the security gate 1 will be described. Each step in FIG. 7 is indicated by S1 to S5.

First, information on which of the flaps 2a and 2b is to be operated to the closed position 21, the forward rotational direction open position 22, or the reverse rotational direction open position 23 is received (S1). That is, as shown in FIGS. 8 and 9, the control unit 11 provides information on whether the passer 34 enters from either the entrance 36 or the exit 37, and permits or prohibits the passage of the passer 34. Or other information. This information is, for example, information determined from a result of reading a passer's card data by a magnetic card reader, an IC card reader, or the like provided at the entrance / exit gate. Alternatively, the information is determined from an authentication medium such as an IC card or a ticket (magnetic card) read by the card information reading device in the ticket gate.

  Next, the control unit 11 checks whether or not the motor 24 is rotating (S2). If the motor 24 is not rotating, the controller 24 rotates the motor 24 (S3). If the motor 24 is rotating, the process proceeds to the next step. That is, the control unit 11 controls the rotation of the motor 24 with respect to the power unit 12.

  Then, based on the above information, the predetermined driving units 8, 9 are connected to the motor 24, and the other driving units 8, 9 are disconnected from the motor 24 (S4). That is, the control unit 11 connects the predetermined driving units 8 and 9 to the motor 24 and disconnects the other driving units 8 and 9 from the motor 24, thereby transmitting the rotation of the motor 24 to the opening and closing of the flaps 2a and 2b. It has a function to make As a result, the driving units 8 and 9 can be simplified, and a compact security gate 1 can be realized. Further, by making the mechanisms of the driving units 8 and 9 of the security gate 1 compact, the manufacturing cost of the security gate 1 can be further reduced, and the occurrence of failure can be further suppressed.

Finally, the motor 24 is rotated to move the predetermined flap 2 to the predetermined closed position 21 or the open positions 22, 23 (S5). With this series of security gate opening / closing methods, the flaps 2a and 2b can be opened / closed and the passage of passersby can be appropriately permitted or prohibited.

  In step 5, the driving units 8 and 9 are composed of a plurality of gears. The gears connected to the motor 24 among the plurality of gears by pushing and pulling the gear connecting rod 15 are engaged with the motor 24, and the other gears are the motors. 24. That is, the drive units 8 and 9 include the right flap rotation gear 8 and the left flap rotation gear 9. The flaps 2a and 2b can be rotated in the normal rotation direction R1 and the reverse rotation direction R2 by pushing and pulling the gear connecting rod 15 by the solenoid 17.
