Description

The present invention relates to a vehicle traffic barrier installed at a toll gate such as an expressway and capable of blocking or permitting vehicle traffic.

  In recent years, ETC (Electronic Toll Collection System) has been introduced as a system for automating toll collection in toll roads such as expressways and parking lots. In this ETC, when the vehicle detector detects the entry of the vehicle to the toll gate, the lane server issues a communication command to the roadside antenna, and based on this, the roadside antenna is mounted on the vehicle mounted on the vehicle. Start communication. Next, the lane server determines whether the vehicle is a normal vehicle or an abnormal vehicle based on information obtained from the vehicle-mounted device by the roadside antenna. When it is determined that the vehicle is normal, the blocking bar of the vehicle traffic barrier is opened, and when it is determined that the vehicle is abnormal, the blocking bar is kept closed so that the vehicle is blocked or permitted. It has become.

  In this ETC, there is an accident in which when the vehicle forcibly passes the vehicle passage breaker even though the blocking rod is closed, the blocking rod and the vehicle are damaged by the collision of the vehicle with the blocking rod. Arise. Therefore, in order to cope with such a problem, a vehicle traffic breaker configured such that the blocking bar performs a release operation so as to release the impact received by the blocking bar at the time of a vehicle collision has been proposed (for example, (See Patent Documents 1 and 2).

  While the vehicle traffic breaker described in these Patent Documents 1 and 2 is normally used without the vehicle colliding with the blocking bar, the blocking bar rotates in the vertical plane and is in a state of lying down horizontally. While blocking the passage of the vehicle, an opening / closing operation is performed to permit the vehicle to enter while standing vertically. When the vehicle collides with the blocking rod, the blocking rod bends along the horizontal plane in the vehicle traveling direction according to the impact, and is in a released state. In this way, the release operation of the vehicle traffic barrier is performed.

Japanese Patent No. 3594957 JP 2003-336232 A

  However, in the vehicle traffic breakers disclosed in Patent Documents 1 and 2, there is no mechanism for automatically returning the bent blocking bar after the release operation to the state before the release operation. It was necessary to approach to the point and manually return the blocking bar to the non-released state.

Therefore, there is a case where it takes a long time to return the blocking rod after the release operation, and there is a problem that a traffic jam of the vehicle occurs during that time.
In this regard, it is conceivable to separately provide a drive unit such as an electric motor for returning the blocking rod after the release operation to the non-release state, but the configuration of the vehicle traffic breaker becomes complicated, and costs, maintenance, etc. It is not preferable from the viewpoint.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a vehicle traffic breaker capable of quickly returning a blocking bar after a release operation with a simple configuration.

In order to achieve the above object, the present invention employs the following means.
In other words, the vehicle traffic barrier according to the present invention is opened and closed by being rotated between a return drive unit and a blocking position for blocking the vehicle and a permitted position for allowing the vehicle to travel by the return drive unit. A release shaft that rotates the blocking rod in a release direction that releases an impact caused by a vehicle, and the release shaft rotates the return drive only when the blocking rod rotates in the release direction. And a transmission mechanism that rotates the release shaft, and the release shaft is rotated by the return drive unit, so that the blocking bar rotates in a return direction that is opposite to the release direction. It is characterized by that.

According to the vehicle traffic breaker having such a feature, the rotation of the return drive unit is not transmitted to the release shaft in the non-release state where the blocking bar is not rotating in the release direction, and the return Only the opening / closing operation of the blocking rod is performed by the drive unit.
On the other hand, when the blocking rod rotates in the release direction due to the collision of the vehicle with the blocking rod, the rotation of the return drive unit is transmitted to the release shaft. Therefore, the return drive unit opens and closes the blocking rod. At the same time as the operation is performed, the release shaft also rotates, and accordingly, the blocking rod rotates in the return direction that is opposite to the release direction.

Further, in the vehicle traffic breaker according to the present invention, the transmission mechanism is interlocked with the rotation of the release shaft and the first rotating disk that reciprocates within a predetermined angle range in conjunction with the opening / closing operation of the blocking bar. A second rotating disk that rotates, a transmission unit that is provided on the first rotating disk and reciprocates in the circumferential direction of the first rotating disk with the reciprocating rotation of the first rotating disk, and the second rotation And a transmitted part that enters the reciprocating range of the transmitting part when the second rotating disk rotates as the blocking bar rotates in the release direction. .
According to the vehicle traffic breaker having such a feature, when the release shaft is rotated by the rotation of the blocking rod in the release direction, and the second turntable is rotated along with this, the transmitted portion of the second turntable Enters the reciprocating range of the transmission part of the first rotating disk.
At this time, when the transmission portion reciprocates in the circumferential direction of the first rotating disc by the reciprocating rotation of the first rotating disc in conjunction with the opening / closing operation of the blocking rod, the transmitting portion abuts on the transmitted portion. The transmitted part is excluded from the reciprocating range. That is, due to the reciprocating movement of the transmission part, the transmitted part is moved to the initial position before entering the reciprocating movement range. When the transmitted part moves in this way, the blocking bar rotates in the return direction by rotating the second turntable and the release shaft along with this movement.
That is, only when the blocking bar rotates in the release direction, the rotation of the return drive unit can be transmitted to the release shaft, and the blocking bar can be rotated in the return direction.
In addition, the vehicle traffic barrier according to the present invention includes a blocking bar that is rotated between a blocking position that blocks vehicle traffic and a permission position that allows the vehicle to travel, and that opens and closes. A release shaft that rotates in a release direction that releases an impact caused by the above, a return drive that can rotate the blocking bar in a direction opposite to the release direction, and only when the blocking bar rotates in the release direction and a transmission mechanism for transmitting the rotation of the return drive unit to the release shaft, the rotation of the release shaft by the return drive unit, and the blocking rod the release direction rotates in the return direction is the opposite direction The transmission mechanism includes a first rotating disk that reciprocally rotates within a predetermined angle range in conjunction with the opening and closing operation of the blocking bar, a second rotating disk that rotates in conjunction with the rotation of the release shaft, and the first Provided on the turntable, A transmission section that reciprocates in the circumferential direction of the first rotating disk as the first rotating disk reciprocates; and the second rotating disk that is provided in the second rotating disk, and the first rotation disk rotates in the release direction. When the two-turn disk rotates, a transmission unit that enters a reciprocating range of the transmission unit may be provided.

  In the vehicle traffic breaker having such a feature, a return drive unit is provided separately from the power for opening and closing the blocking bar. And in the non-release state in which the blocking bar is not rotating in the release direction, the rotation of the return drive unit is not transmitted to the release shaft. On the other hand, when the blocking bar rotates in the release direction due to the collision of the vehicle with the blocking bar, the rotation of the return drive unit is transmitted to the release shaft, and the blocking direction is opposite to the release direction. To turn.

  Furthermore, in the vehicle traffic breaker according to the present invention, the first rotating disk and the second rotating disk are arranged to face each other with their center axes aligned with each other, and the transmission unit is arranged on the first rotating disk. It is preferable that the first convex portion protrudes from the opposing surface, and the transmitted portion is a second convex portion that protrudes from the opposing surface of the second rotating disk and can contact the first convex portion.

  As a result, when the release shaft and the second turntable are rotated by the rotation of the blocking rod in the release direction, the second convex portion of the second turntable is within the reciprocating movement range of the first convex portion of the first turntable. invade. Then, when the first convex portion reciprocates due to the reciprocating rotation of the first rotating disk interlocked with the opening / closing operation of the blocking bar, the first convex portion is excluded by pushing the second convex portion out of the reciprocating movement range. Thus, with a simple configuration, the rotation of the return drive unit can be reliably transmitted to the release shaft only when the blocking bar rotates in the release direction.

Further, in the vehicle traffic breaker according to the present invention, the first turntable and the second turntable are arranged so as to be separated from each other so that their central axes are parallel to each other, and It is a claw part extended toward the radial direction outer side from one rotary disk, Comprising: The convex part which protrudes from the surface of a said 2nd rotary disk, and can contact | abut to the said claw part may be sufficient.

  As a result, when the release shaft and the second turntable are rotated by the rotation of the blocking bar in the release direction, the second convex portion of the second turntable enters the reciprocating range of the claw portion of the first turntable. . Then, when the claw portion reciprocates due to the reciprocating rotation of the first rotating disk interlocked with the opening / closing operation of the blocking rod, the claw portion is excluded from the reciprocating movement range so as to guide the convex portion. Thus, similarly to the above, the rotation of the return drive unit can be reliably transmitted to the release shaft only when the blocking bar rotates in the release direction with a simple configuration.

  Moreover, in the vehicle traffic breaker according to the present invention, the first rotating disk and the second rotating disk are arranged to face each other with their center axes aligned with each other, and the transmission unit is opposed to the first rotating disk. It is a nail | claw part which protrudes from a surface, Comprising: The said to-be-transmitted part may be the edge part of the said circumferential direction in the groove part formed along the circumferential direction of a said 2nd rotary disk.

  As a result, when the release shaft and the second rotating disk rotate due to the rotation of the blocking bar in the release direction, the end of the groove part of the second rotating disk enters the reciprocating range of the claw part of the first rotating disk. . Then, when the claw portion reciprocates by the reciprocating rotation of the first rotating disk interlocked with the opening / closing operation of the blocking rod, the claw portion comes into contact with the end portion of the groove portion to guide the end portion from the reciprocating movement range. Exclude. Thus, similarly to the above, the rotation of the return drive unit can be reliably transmitted to the release shaft only when the blocking bar rotates in the release direction with a simple configuration.

  According to the vehicle traffic breaker of the present invention, the rotation of the return drive unit for causing the blocking bar to open and close is transmitted to the release shaft only when the blocking bar rotates in the release direction. Therefore, the blocking bar after the release operation can be quickly returned with a simple configuration without providing a separate drive for release return.

That is, the vehicle detector 131 detects, for example, the entry of the vehicle to the toll gate by a first optical sensor installed on the entrance side of the toll gate (the rear side in the vehicle traveling direction G of the circuit breaker 10). The exit of the vehicle from the toll gate is detected by a second optical sensor installed on the exit side of the toll gate (front side in the vehicle traveling direction G of the circuit breaker 10). The vehicle detector 131 outputs a signal corresponding to the entry and exit of the vehicle to the lane server 130 based on the detection of the entry and exit of the vehicle.

The roadside antenna 132 is installed, for example, on the rear side of the vehicle traveling direction G from the circuit breaker 10, and when the vehicle passes through the toll gate, it transmits and receives necessary information to and from the vehicle-mounted device mounted on the vehicle. A signal based on transmission / reception of information is output to the lane server 130.
The lane server 130 then sends a vehicle passage permission command and a vehicle exit detection signal to the control unit 90 based on the input of signals from the vehicle detector 131 and the roadside antenna 132. The control unit 90 causes the blocking bar 30 to perform an opening operation by driving the electric motor 62 to rotate forward based on the vehicle passage permission command. On the other hand, the control unit 90 causes the blocking rod 30 after the opening operation to perform the closing operation by driving the electric motor 62 to rotate reversely based on the vehicle exit detection signal.

  The operation unit 133 is installed in a room of a tollgate in the vicinity of the toll booth. For example, when the “open button” or the “close button” is pressed, the operation bar 133 is blocked against the lane server 130 by the blocking bar 30. Outputs the open / close request. The lane server 130 sends an opening / closing command to the control unit 90 based on the opening / closing request, and the control unit 90 performs the opening / closing operation of the blocking rod 30 by rotating the electric motor 62 based on the opening / closing command. The operation unit 133 may be installed in a monitoring center or the like located away from the toll gate.

  Further, the operation unit 133 is connected in series to the control unit 90 and, for example, sends a release return command for the blocking rod 30 to the control unit 90 when the “release return button” is pressed. . When the release return command is input, the control unit 90 drives the latch device 58 and then drives the electric motor 62.

  Next, the effect | action of the circuit breaker 10 of this embodiment is demonstrated. When the vehicle has not entered the vehicle traffic path R and the breaker 10 is in the standby state, the blocking bar 30 is brought into a non-released state as shown in FIGS. 1 and 2, and the blocking position is the home position. S. In this non-released state, as shown in FIG. 6, the holding spring 55 urges the locking portion 53 toward the rear end side of the support arm 20, whereby the shaft portion 51 a that has entered the hooking groove 53 a. Is prevented from escaping from the hook groove 53a, thereby preventing the blocking rod 30 from rotating in the release direction T1. Since the urging force of the holding spring 55 is set to be larger than the urging force of the release spring 41 in the non-release state, the shaft portion 51a is prevented from escaping from the hook groove 53a only by the urging force of the release spring 41. The rod 30 does not rotate in the release direction T1.

  First, the processing procedure of the opening / closing operation of the blocking bar 30 when the vehicle enters the toll gate having the circuit breaker 10 in the standby state as described above will be described. The opening / closing operation of the blocking rod 30 is performed under the control of the lane server 130. FIG. 11 is a flowchart showing a flow of processing of the opening / closing operation of the blocking bar 30 executed by the lane server 130.

  First, the lane server 130 determines whether or not the vehicle detector 131 has detected the entry of the vehicle to the toll gate, that is, whether or not the ON signal (vehicle detection signal) from the vehicle detector 131 has been input. (S11). As a result, when it is determined that an OFF signal is input from the vehicle detector 131 (S11: No), the lane server 130 waits until an ON signal is input from the vehicle detector 131. On the other hand, when it is determined that an ON signal is input from the vehicle detector 131 (S11: Yes), the lane server 130 sends a reception command for in-vehicle device information to the roadside antenna 132 (S12), and the roadside antenna 132 is output. Starts communication with the vehicle-mounted device mounted on the vehicle based on this signal.

  Next, the lane server 130 determines whether the vehicle about to pass through the toll gate is a normal vehicle or an abnormal vehicle based on the vehicle-mounted device information received by the roadside antenna 132 (S13). As a result, when it is determined that the vehicle is an abnormal vehicle (S13: No), the lane server 130 performs an abnormal process (S14) and maintains the blocking rod 30 at the blocking position S without performing the opening operation of the blocking rod 30. . Thereby, the process of the lane server 130 at the time of determining that it is an abnormal vehicle in S13 is complete | finished.

  On the other hand, when it is determined that the vehicle is a normal vehicle in S13 (S13: Yes), the lane server 130 sends a vehicle passage permission command to the electric motor 62 and rotates the output shaft 62a in the normal direction to thereby support the support arm 20 and the blocking rod. 30 is rotated from the blocking position S to the permission position K (S15). That is, the lane server 130 causes the support arm 20 and the blocking bar 30 to perform an opening operation. Thereby, the circuit breaker 10 will be in the state which permitted the passage of the vehicle.

  After S15, the lane server 130 determines whether or not the vehicle has detected exit from the toll gate, that is, whether or not an OFF signal has been input from the vehicle detector 131 as a result of completion of vehicle detection by the vehicle detector 131. Is determined (S16). If it is determined that the ON signal is still input from the vehicle detector 131 (S16: No), the lane server 130 waits until an OFF signal is input from the vehicle detector 131. On the other hand, when it is determined that an OFF signal is input from the vehicle detector 131 (S16: Yes), the lane server 130 sends a vehicle exit detection signal to the control unit 90. Based on the vehicle exit detection signal, the control unit 90 rotates the output shaft 62a of the electric motor 62 in the reverse direction to rotate the support arm 20 and the blocking bar 30 from the release position K to the blocking position S (S17). Thereby, the circuit breaker 10 is in a state where the passage of the vehicle is blocked, and the processing of the lane server 130 when determining that the vehicle is a normal vehicle in S13 ends.

Here, as described above, when the lane server 130 determines that the vehicle is abnormal and performs abnormality processing, the blocking rod 30 is maintained at the blocking position S, so that the vehicle collides with the blocking rod 30. There is a case. Further, even when the lane server 130 determines that the vehicle is a normal vehicle and causes the blocking bar 30 to perform an opening operation, the vehicle may collide with the blocking bar 30 if the approach speed of the vehicle is too fast. At this time, in this embodiment, the release operation of the blocking rod 30 is performed.
That is, when a vehicle traveling in the vehicle traveling direction G collides with the bar portion 31 of the blocking bar 30, the impact force acts as a rotational moment that rotates the blocking bar 30 in the release direction T1. Then, due to the rotational moment, the shaft portion 51a of the locked portion 51 climbs over the mountain portion 53b against the urging force of the holding spring 55, and the shaft portion 51a escapes from the hooking groove 53a. As a result, the holding of the blocking bar 30 in the non-released state is released, and the blocking bar 30 is rotated in the release direction T <b> 1 according to the bias of the release spring 41 as shown in FIG. 7.

  Thus, when the blocking bar 30 rotates in the release direction T1, the second rotary plate 82 in the clutch mechanism 80 rotates with the rotation of the release shaft 22. As a result, as shown in FIG. 9C, the second convex portion 82a arranged at an angular position of 90 ° enters the reciprocating movement range of the first convex portion 81a in the first rotating disk 81, and the blocking rod 30 is moved. When the second convex portion 82a is rotated to the released state, the second convex portion 82a moves to the angular position 0 ° and contacts the first convex portion 81a.

  When the blocking bar 30 rotates in the release direction T1, the latch 58a itself is brought into contact with the latch hook 59 while the blocking bar 30 is rotating in the release direction T1. Retracting, the latch 58a gets over the latch hook 59. Then, when the blocking bar 30 is in the released state, as shown in FIG. 7, the latch 58 a can come into contact with the surface of the latch hook 59 that faces the vehicle passage R side. Is prevented from rotating in the return direction T2, and the released state of the blocking bar 30 is held in a locked state. This completes the release operation.

  Next, when the blocking bar 30 is in the released state after the release operation is completed, the returning operation for rotating the blocking bar 30 in the return direction T2 to return to the non-released state will be described. This return operation is performed on the basis of a release return command that is sent, for example, by an operation of the operation unit 133 by a staff at a toll gate when the blocking rod 30 after the release operation is in the release state. FIG. 12 is a flowchart showing a flow of processing of the return operation of the blocking rod 30 executed by the control unit 90.

  First, the control unit 90 determines whether an ON signal is input from the operation unit 133, that is, whether a release return command is input from the operation unit 133 (S21). As a result, when it is determined that an OFF signal is input from the operation unit 133 (S21: No), the process waits until an ON signal is input from the operation unit 133.

  When the control unit 90 determines that an ON signal has been input from the operation unit 133 (S21: Yes), the control unit 90 sends a command to flow current to the solenoid in the latch device 58, thereby causing the latch 58a to retract. Thus, the locked state of the latch device 58 is released (S22). As a result, the holding state of the blocking bar 30 in the released state is released, and the blocking bar 30 becomes rotatable in the return direction T2.

  Next, the control unit 90 rotates the electric motor 62 of the return drive unit 61 in the normal direction to cause the support arm 20 to open (S23). That is, by rotating the electric motor 62 forward, the support arm 20 is rotated 90 ° from the horizontal state to the vertical state. Then, in conjunction with the rotation of the support arm 20, the first turntable 81 rotates counterclockwise as shown in FIG. As a result, the first convex portion 81a of the first turntable 81 moves from the angular position 0 ° to the angular position 90 °.

  At this time, since the second protrusion 82a is in contact with the first protrusion 81a with respect to the first protrusion 81a, the second protrusion 82a is also moved in the same direction as the first protrusion 81a moves. Moving. And if the 1st convex part 81a moves to 90 degrees of angular positions, the 2nd convex part 82a will be excluded from the reciprocation range of this 1st convex part 81a so that it may be extruded by the 1st convex part 81a. Thus, the second convex portion 82a moves from the angular position 0 ° to the initial angular position 90 °.

  When the second convex portion 82a moves in this manner, the second rotary plate 82 also rotates 90 ° counterclockwise, and in conjunction with this, the release shaft 22 and the blocking rod 30 also rotate 90 ° in the return direction T2. As a result, the blocking bar 30 returns to the non-released state parallel to the support arm 20, and the blocking bar 30 is in the permitted position K in the vertical direction. As described above, when the blocking bar 30 rotates in the release direction T1 from the non-released state, the rotation of the return drive unit 61 is transmitted to the release shaft 22, and thereby the blocking bar 30 rotates in the return direction T2. .

  Here, an example in which the support arm 20 is opened in the non-release state in which the blocking bar 30 is rotated 90 ° from the non-release position has been described. However, the blocking bar 30 is not necessarily rotated to the released state. It is only necessary that the support arm 20 be opened at least in the state where the blocking bar 30 is rotated in the release direction T1 from the non-release state. As a result, the second convex portion 82a of the second rotary plate 82 enters the reciprocating movement range of the first convex portion 81a of the first rotary disc 81, so that the first convex portion 81a interlocked with the opening operation of the support arm 20 is performed. By movement, the second convex portion 82a moves to the initial position, and the blocking bar 30 returns to the non-released state.

  Thereafter, the control unit 90 reversely rotates the electric motor 62 of the return drive unit 61 to cause the support arm 20 to close (S24). That is, by rotating the electric motor 62 in the reverse direction, the support arm 20 is rotated by 90 ° from the vertical state to the horizontal state. As a result, the blocking rod 30 returns from the permission position K to the blocking position S. Further, in conjunction with the rotation of the support arm 20, the first convex portion 81a of the first turntable 81 moves from the angular position 90 ° to 0 °. At this time, the first convex portion 81a does not interfere with the second convex portion 82a, and the first convex portion 81a and the second convex portion 82a are in the initial state shown in FIG. This completes the return operation.

As described above, according to the breaker 10 of the present embodiment, when the blocking bar 30 is in the non-release state, the rotation of the return drive unit 61 is not transmitted to the release shaft 22, and the return drive unit Only the opening / closing operation of the blocking rod 30 is performed by 61.
On the other hand, when the blocking rod 30 rotates in the release direction T1 due to the collision of the vehicle with the blocking rod 30, the rotation of the return driving portion 61 is transmitted to the release shaft 22. 61, at the same time as the blocking bar 30 is opened, the release shaft 22 is rotated, and the blocking bar 30 is rotated in the return direction T2.

  Accordingly, the blocking rod 30 after the release operation can be quickly returned with a simple configuration without providing a separate release return drive unit or the like. Therefore, for example, it is not necessary to manually return the blocking bar 30 such as a toll booth or the like, so that it is possible to avoid the occurrence of vehicle traffic on the vehicle traffic path R. Further, since only one return drive unit 61 is sufficient as a drive source, it is possible to reduce costs and save maintenance.

  Further, in the circuit breaker 10 of the present embodiment, when the release shaft 22 is rotated by the rotation of the blocking bar 30 in the release direction T1, and the second rotating plate 82 is rotated accordingly, the second rotating plate 82 is rotated. The second convex portion 82 a enters the reciprocating movement range of the first convex portion 81 a of the first rotating disk 81. At this time, when the first turntable 81 reciprocates in the circumferential direction of the first turntable by the reciprocating rotation of the first turntable 81 in conjunction with the opening / closing operation of the blocking rod 30, the first protrusion 81a. Abuts against the second convex portion 82a, and the second convex portion 82a is pushed out of the reciprocating movement range and eliminated.

  That is, the reciprocating movement of the first convex portion 81a moves to the initial position before entering the reciprocating movement range of the second convex portion 82a, and accordingly, the second turntable 82 and the release shaft 22 rotate and prevent. The rod 30 is rotated in the return direction. Accordingly, it is possible to easily realize a mechanism for transmitting the rotation of the return drive unit 61 to the release shaft 22 and rotating the blocking bar 30 in the return direction T2 only when the blocking bar 30 rotates in the release direction T1. .

  Next, the circuit breaker according to the second embodiment of the present invention will be described in detail with reference to FIGS. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

As shown in FIG. 14, the circuit breaker 10 of the second embodiment is different from the transmission mechanism 70 of the first embodiment in the configuration of the transmission mechanism 100 in the drive unit 60.
The transmission mechanism 100 according to the second embodiment includes a first pulley 101 that is integrally fixed to a drive shaft 64, and a second pulley 102 that is disposed below the first pulley 101 in parallel with the first pulley and the central axis. A first belt 103 wound around the first pulley 101 and the second pulley 102, a first umbrella gear 104 connected to the second pulley 102 and rotating integrally therewith, and the first umbrella gear 104 The second bevel gear 106 is engaged with the second bevel gear 106 and the clutch mechanism 110 is interposed between the second bevel gear 106 and the release shaft 22.

  The clutch mechanism 110 in the transmission mechanism 100 is connected to the second umbrella gear 106 and rotates integrally with the second umbrella gear 106, and connected to the release shaft 22 to the release shaft 22. And a second turntable 112 that rotates together with the second turntable 112. The first turntable 111 and the second turntable 112 are arranged apart from each other in the longitudinal direction of the support arm 20 so that the respective central axes are parallel.

  On the first rotating disk 111, the rotation of the drive shaft 64 of the return drive unit 61 causes the first pulley 101, the first belt 103, the second pulley 102, the first umbrella gear 104, and the second umbrella gear 106 to move. It is transmitted sequentially. Thus, the first turntable 111 is configured to reciprocate within a predetermined range in conjunction with the opening / closing operation of the blocking bar 30 at all times. In the present embodiment, in conjunction with the rotation of the blocking bar 30 by 90 ° between the blocking position S and the permission position K, the first turntable 111 is also configured to rotate within a predetermined angle range. .

  Further, a claw portion 111 a extending to the vicinity of the center of the lower surface of the second rotary disk 112 is provided on the outer peripheral surface of the first rotary disk 111. As shown in FIG. 15, the claw portion 111 a has a rotation direction (hereinafter referred to as a normal rotation direction) of the first turntable 111 that is interlocked with the opening operation of the support arm 20 toward the radially outer side of the first turntable 111. It extends so as to incline toward the rear side.

  When the blocking bar 30 is in the blocking position S, the tip of the claw portion 111a is positioned at the angular position 270 ° of the second turntable 112, as shown in FIG. Then, when the blocking rod 30 rotates from the blocking position S toward the permission position K, as shown in FIG. 15B, the tip of the claw portion 111a is rotated by the first rotation with the first rotation of the first turntable 81. The second rotary disk 112 is moved to a position at an angular position of 90 ° so as to draw an arc m centering on the disk 111. Note that the central axis of the second rotating disk 112 is included in the area inside the arc m.

  That is, as the first turntable 111 reciprocates within a predetermined angle range in conjunction with the opening / closing operation of the blocking bar 30, the claw portion 111a is circumferentially moved in the circumferential direction of the first turntable 111 by the predetermined angle range. It is configured to reciprocate. A region inside the arc m, which is a range in which the claw portion 111a reciprocates, is a reciprocating range of the claw portion 111a.

  Further, since the second rotating disk 112 is connected to the release shaft 22, it is configured to rotate in conjunction with the release shaft 22. A convex portion 112 a that protrudes downward is provided at a position on the outer circumferential side of the lower surface of the second rotating disk 112. When the blocking bar 30 is in a non-released state, the convex portion 112a is disposed at an angular position of 90 ° shown in FIG. Then, when the blocking rod 30 rotates in the release direction T1 from the blocking position S, with the rotation of the release shaft 22 and the second turntable 112, the convex portion 112a moves and enters the reciprocating movement range of the claw portion 111a, Finally, as shown in FIG. 15C, the convex portion 112a is disposed at an angular position of 0 °, and is in a state of being in contact with the surface of the claw portion 111a facing forward in the forward rotation direction.

  In such a circuit breaker 10 of the second embodiment, in order to return the blocking bar 30 to the non-released state after the blocking bar 30 is in the released state, the flowchart of FIG. Processing by the control unit 90 shown is performed.

  When the blocking bar 30 is in the released state and the claw portion 111a of the first turntable 111 and the convex portion 112a of the second turntable 112 are in the state of FIG. When the opening operation (S23) is performed, the electric motor 62 is rotated forward, and the support arm 20 is rotated 90 ° from the horizontal state to the vertical state. Then, the first turntable 81 rotates in the forward rotation direction in conjunction with the rotation of the support arm 20, so that the claw portion 111a of the first turntable 81 follows the arc m as shown in FIG. Move in the forward rotation direction.

  At this time, since the convex portion 112a of the second turntable 112 is in contact with the claw portion 111a of the first turntable 111 from the front side in the forward rotation direction, the convex portion 112a is moved to the second position along with the movement of the claw portion 111a. Move in the circumferential direction of the turntable. Thus, the convex portion 112a is guided by the claw portion 111a and excluded from the reciprocating movement range of the first convex portion 81a. Thus, the second convex portion 82a moves from the angular position 0 ° to the initial angular position 90 °.

  When the second convex portion 82a is moved in this manner, the second turntable 82 is also rotated 90 ° counterclockwise in FIG. 16, and in conjunction with this, the release shaft 22 and the blocking rod 30 are also rotated 90 ° in the return direction T2. Move. As a result, the blocking bar 30 returns to a non-released state parallel to the support arm 20.

  Also in the circuit breaker 10 of the second embodiment, when the blocking rod 30 rotates in the release direction T1 due to the collision of the vehicle with the blocking rod 30 as in the first embodiment, the return drive unit 61 rotates. Is transmitted to the release shaft 22, the release drive unit 61 causes the blocking rod 30 to open, and at the same time, the release shaft 22 rotates. Accordingly, the blocking rod 30 rotates in the return direction T2. Move. Therefore, the blocking rod after the release operation can be quickly returned with a simple configuration without providing a separate release return drive unit or the like.

  In the circuit breaker 10 of the second embodiment, when the release shaft 22 is rotated by the rotation of the blocking bar 30 in the release direction T1, and the second rotating disk 112 rotates accordingly, the second rotating disk The convex portion 112 a of 112 enters the reciprocating range of the claw portion 111 a of the first turntable 111. At this time, the first rotating disk 111 reciprocates in conjunction with the opening / closing operation of the blocking bar 30 so that the claw portion 111a reciprocates in the circumferential direction of the first rotating disk 111. The convex portion 112a is guided and excluded from the reciprocating movement range. That is, by the reciprocating movement of the claw portion 111a, the convex portion 112a is moved to the initial position before entering the reciprocating movement range, and accordingly, the second turntable 112 and the release shaft 22 are rotated, and the blocking rod 30 is returned. Will rotate in the direction. Accordingly, as in the first embodiment, a mechanism for transmitting the rotation of the return drive unit 61 to the release shaft 22 and rotating the blocking bar 30 in the return direction T2 only when the blocking bar 30 rotates in the release direction T1. It can be easily realized.

  Next, the circuit breaker according to the third embodiment of the present invention will be described in detail with reference to FIGS. In the third embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 17, the circuit breaker 10 of the third embodiment is different from the clutch mechanism 80 of the first embodiment in the configuration of the clutch mechanism 180 in the transmission mechanism 70 of the drive unit 60.

  The clutch mechanism 180 of the third embodiment is connected to the fourth pulley 78 and rotates integrally with the fourth pulley 78, and connected to the release shaft 22 and rotates integrally with the release shaft 22. And a second turntable 182. The first rotating disk 181 and the second rotating disk 182 are arranged so as to be opposed to each other in the vertical direction with their central axes aligned with each other.

  In the first rotating disk 181, the rotation of the drive shaft 64 of the return drive unit 61 is caused by the first pulley 71, the first belt 73, the second pulley 72, the first umbrella gear 74, the second umbrella gear 76, It is transmitted via the third pulley 77, the second belt 79 and the fourth pulley 78. Thus, the first rotating disk 181 is configured to reciprocate within a predetermined range in conjunction with the opening / closing operation of the blocking bar 30 at all times. In the present embodiment, in conjunction with the rotation of the blocking bar 30 by 90 ° between the blocking position S and the permission position K, the first turntable 181 is also configured to rotate within a range of 90 °. Yes.

  Further, as shown in FIG. 18, the axis of the first turntable 181 is centered on the axis of the first turntable 181 at a position on the outer peripheral side of the surface of the first turntable 181 facing the second turntable 182. A pair of claw portions (transmission portions) 181a and 181a having point symmetry of 180 ° are provided so as to protrude. Each of these claw portions 181a and 181a has a columnar shape extending in parallel with the axis of the first rotating disk 181.

  When the blocking bar 30 is at the blocking position S, the claw portions 181a and 181a are arranged at the angular positions 0 ° and 180 ° shown in FIG. When the blocking rod 30 rotates from the blocking position S toward the permission position K, the claw portions 181a and 181a rotate counterclockwise as shown in FIG. It moves, and finally it will be in the state arrange | positioned at angular position 90 degrees 270 degrees. On the other hand, when the blocking bar 30 is rotated from the permission position K to the blocking position S, the claw portions 181a and 181a at the angular positions 90 ° and 270 ° rotate clockwise as the first rotating disk 181 rotates. Finally, the angular positions are 0 ° and 180 °.

  That is, the claw portions 181a and 181a move in the circumferential direction of the first rotating disk 181 in the circumferential direction of the first rotating disk 181 as the first rotating disk 181 reciprocates in a predetermined angle range in conjunction with the opening / closing operation of the blocking bar 30. In this embodiment, it is configured to reciprocate in an angle range of 90 °. The movement trajectory from the angular position 0 ° to 90 °, which is the range in which the claw portions 181a and 181a reciprocate, is defined as the reciprocating range of the claw portions 181a and 181a.

Further, since the second rotating disk 182 is connected to the release shaft 22, the second rotating plate 182 is configured to rotate in conjunction with the release shaft 22. A pair of grooves 182a and 182a penetrating in the thickness direction of the second rotary disk 182 are formed on the outer peripheral portion of the second rotary disk 182 facing the first rotary disk 181. These groove portions 182a and 182a have an arc shape extending around the axis of the second rotary disk 182, and are symmetric with respect to 180 ° about the axis so as to sandwich the axis of the second rotary disk 182. Is arranged.
The radial position of the groove 182a from the central axis of the second rotary disk 182 is the same as the radial position of the claw parts 181a and 181a from the central axis of the first rotary disk 181. Accordingly, the claw portions 181a and 181a of the first rotary disk 181 are inserted into the groove portions 182a and 182a in a one-to-one relationship.

Of the pair of circumferential end portions in each of the groove portions 182a and 182a, the end portion located on the rear side in the clockwise direction in FIG. The contact end portions 182b and 182b are provided.
When these blocking bars 30 are in a non-released state, the contact end 182b of the groove 182a into which the claw 181a at the angular position 0 ° is inserted is disposed at the angular position 90 °, and the claw at the angular position 180 °. A contact end portion 182b of the groove portion 182a into which the 181a is inserted is disposed at an angular position of 270 °.

  Then, when the blocking rod 30 rotates in the release direction T1 from the blocking position S, the groove portions 182a and 182a move clockwise as the release shaft 22 and the second rotary plate 182 rotate, so that the contact end portion 182b, 182b enters the reciprocating range of the claws 181a and 181a. As a result, the grooves 182a and 182a that are initially arranged at the angular position of 90 ° are arranged at the angular position of 0 °, and the grooves that are initially arranged at the angular position of 270 ° are arranged at the angular position of 180 °.

  In such a circuit breaker 10 of the second embodiment, in order to return the blocking bar 30 to the non-released state after the blocking bar 30 is in the released state, the flowchart of FIG. Processing by the control unit 90 shown is performed.

  When the blocking bar 30 is in the released state and the claw portions 181a and 181a of the first rotating plate 181 and the contact end portions 182b and 182b of the second rotating plate 182 are in the state of FIG. When the opening operation (S23) of the support arm 20 by 90 is performed, the electric motor 62 is rotated forward, and the support arm 20 is rotated 90 ° from the horizontal state to the vertical state. Then, the first turntable 81 rotates in the forward rotation direction in conjunction with the rotation of the support arm 20, so that the claws 181a and 181a of the first turntable 181 are moved in the forward rotation direction as shown in FIG. That is, it moves 90 ° counterclockwise.

  At this time, the contact end portions 182b of the groove portions 182a and 182a of the second rotary disk 182 are in contact with the claw parts 181a and 181a of the first rotary disk 181 from the front side in the forward rotation direction. With the movement of 181a, the contact end portions 182b and 182b and the groove portions 182a and 182a move in the circumferential direction of the second turntable 182. That is, the contact end portions 182b and 182b are guided by the claw portions 181a and 181a so as to be excluded from the reciprocal movement range of the claw portions 181a and 181a. As a result, the contact end portions 182b and 182b move from the angular positions 180 ° and 0 ° to the initial angular positions 90 ° and 270 °, respectively.

  When the contact end portions 182b and 182b are moved in this manner, the second turntable 182 is also rotated 90 ° counterclockwise in FIG. 19, and in conjunction with this, the release shaft 22 and the blocking bar 30 are also moved 90 in the return direction T2. ° Rotate. As a result, the blocking bar 30 returns to a non-released state parallel to the support arm 20.

  Also in the circuit breaker 10 of the third embodiment, when the blocking bar 30 rotates in the release direction T1 due to the collision of the vehicle with the blocking bar 30 as in the first and second embodiments, the return drive unit Since the rotation of 61 is transmitted to the release shaft 22, the release shaft 22 is rotated simultaneously with the opening of the blocking rod 30 by the return drive unit 61. Rotate to T2. Therefore, the blocking rod 30 after the release operation can be quickly returned with a simple configuration without separately providing a drive unit for release return.

  Further, in the circuit breaker 10 of the second embodiment, when the release shaft 22 is rotated by the rotation of the blocking bar 30 in the release direction T1, and the second rotating disk 182 is rotated accordingly, the second rotating disk The contact end portions 182b and 182b of the groove portions 182a and 182a of the 182 enter the reciprocating movement range of the claw portions 181a and 181a of the first rotating plate 181. At this time, the first rotary disk 181 reciprocates in conjunction with the opening / closing operation of the blocking bar 30, so that the claw parts 181 a and 181 a reciprocate in the circumferential direction of the first rotary disk 111, thereby 181a and 181a guide the contact end portions 182b and 182b so that they are excluded from the reciprocating movement range.

  That is, the reciprocating movement of the claw portions 181a and 181a moves the contact end portions 182b and 182b to the initial positions before entering the reciprocating movement range, and accordingly, the second turntable 182 and the release shaft 22 rotate. The blocking bar 30 is rotated in the return direction. Thus, as in the first and second embodiments, the rotation of the return drive unit 61 is transmitted to the release shaft 22 only when the blocking bar 30 rotates in the release direction T1, and the blocking bar 30 rotates in the return direction T2. This mechanism can be easily realized.

  In the above embodiment, the rotation of the return drive unit 61 is transmitted to the release shaft 22, but the release shaft 22 is rotated by a drive unit such as a motor other than the return drive unit 61. There may be.

  Moreover, it may replace with the latch mechanism 57 and the structure which provided the ball catch 120 as shown in FIG. The ball catch 120 includes a male member 121 provided on the bar portion 31 of the blocking bar 30 and a female member 122 provided on a side surface of the circuit breaker body 11 facing the vehicle traveling path R side. When the blocking bar 30 rotates from the non-released state to the released state, the convex portion 121a of the male member 121 on the blocking rod 30 side enters the concave portion 122a of the female member 122.

  At this time, the pair of balls 122b and 122b urged from the side surface of the concave portion 122a presses the convex portion 121a so that the male member 121 and the female member 122 are engaged. Accordingly, the blocking bar 30 is fixed in the released state, and the blocking bar 30 in the released state can be prevented from being inadvertently rotated.

  When the blocking bar 30 rotates from the released state to the non-released state S, the convex portion 121a is opposed to the concave portion 122a against the urging force of the balls 122b and 122b by the rotational force of the blocking rod 30 in the return direction T2. By escaping from the inside, the engaged state between the male member 121 and the female member 122 is released. Thereby, since the locked state of the blocking bar 30 can be released regardless of a command from the control unit 90, the configuration of the breaker 10 itself can be simplified.

Next, a circuit breaker according to a fourth embodiment of the present invention will be described in detail with reference to the drawings.
As shown in FIGS. 21 to 22, the breaker 410 according to the second embodiment includes a breaker body 411, a support arm 420 supported by the breaker body 411, and a blocking bar supported by the support arm 420. 430. Further, the breaker 410 is provided with a return drive unit 440 and a control unit (not shown). In the circuit breaker 410, power for opening and closing the blocking bar 430 and power for causing the blocking bar 430 to return are separately provided.

  The circuit breaker body 411 is fixedly installed on the side of the vehicle traffic path R in the toll booth on the highway. An opening / closing shaft 412 (see FIG. 22) is provided on a surface of the circuit breaker body 411 facing the vehicle traveling direction G rear side. The opening / closing shaft 412 can be driven to rotate about a horizontal axis along the vehicle traveling direction G by an opening / closing motor (not shown) provided in the circuit breaker body 411. The opening / closing motor is a so-called servo motor that can arbitrarily control the rotation speed and rotation angle, and is connected to a control unit 490 described later, and is configured to rotate forward and backward based on a command from the control unit 490. ing. The location where the breaker body 411 is installed is not limited to the toll gate on the highway, and may be a toll gate in a parking lot, for example.

The support arm 420 includes an arm main body 421 and a release shaft 422 (not shown in FIGS. 21 and 22, see FIG. 23).
The arm body 421 is fixedly supported by the opening / closing shaft 412 so that the diameter direction of the opening / closing shaft 412 is the longitudinal direction. The arm body 421 is rotated by 90 ° along the vertical plane between the horizontal state in which the longitudinal direction of the arm body 421 is parallel to the horizontal direction and the vertical state in parallel to the vertical direction as the opening / closing shaft 412 rotates. In this range, it can be rotated around the axis of the opening / closing shaft 412.

  The arm main body 421 includes an upper plate portion 421a and a lower plate portion 421b that face each other in the vertical direction in a horizontal state, and an intermediate plate portion 421c that connects the upper plate portion 421a and the lower plate portion 421b. I have. That is, the arm main body 421 has a substantially U-shaped cross section perpendicular to the longitudinal direction. Further, in the U-shaped cross section, an intermediate plate portion 421c that is one side connecting two opposite sides is fixedly supported by the opening / closing shaft 412.

  The release shaft 422 is supported at the tip of the arm body 421, that is, the end of the arm body 421 on the vehicle passage R side when the support arm 420 is in the horizontal state (the left side in FIGS. 21 and 22). The release shaft 422 is rotatable about an axis that is orthogonal to the longitudinal direction of the arm body 421 and extends along the vertical plane. Thus, when the support arm 420 is in a horizontal state, the release shaft 422 can be rotated around the vertical axis.

The blocking bar 430 is fixedly supported by the release shaft 422 so as to extend in the diameter direction of the release shaft 422. When the support arm 420 is in a horizontal state, a portion of the blocking rod 430 on the side of the vehicle passage R viewed from the release shaft 422 is a rod portion 431 that has a long shape and blocks the vehicle from traveling. ing. Further, a portion of the blocking bar 430 on the opposite side of the bar portion 431 across the release shaft 422 is a base portion 432 that can be stored inside the U-shaped cross section of the arm body 421.
Such a blocking bar 430 can be rotated around the axis of the release shaft 422 as the release shaft 422 rotates.

In this blocking bar 430, as shown in FIG. 21, the extending direction of the blocking bar 430 is parallel to the longitudinal direction of the support arm 420, that is, the blocking bar 430 extends in the radial direction of the opening / closing shaft 412. The state is a non-release state.
Further, as shown in FIG. 22, the blocking bar 430 rotates 90 ° from the non-released state in the vehicle traveling direction G as the release shaft 422 rotates, and the extending direction of the blocking bar 30 is the support arm 420. A state in which the blocking bar 430 extends in parallel with the opening / closing shaft 412 and the vehicle traveling direction G is a released state.
Hereinafter, the direction in which the blocking bar 430 rotates from the non-release state to the release state, that is, the direction in which the release operation is performed is referred to as a release direction T1, and conversely, the direction in which the block 430 rotates from the release state to the non-release state The direction in which the return operation is performed is set as a return direction T2.

  Further, in the blocking bar 430, as shown in FIG. 21, since the support arm 420 is in a horizontal state and the blocking bar 430 is in a non-released state, the blocking bar 430 is in a substantially horizontal state. At the same time, the blocking position S is a state that extends in a direction substantially perpendicular to the vehicle traveling direction G and prevents the vehicle from traveling. In addition, when the support arm 420 is in the vertical state and the blocking bar 430 is in the non-released state, the state where the blocking bar 430 stands up in the vertical direction and allows the vehicle to pass is set as the permission position K. Yes.

  In the present embodiment, the support arm 420 rotates in the range of 90 ° as the opening / closing shaft 412 rotates, so that the non-released blocking rod 430 is moved between the blocking position S and the permission position K. It opens and closes between them. Hereinafter, an operation in which the support arm 420 rotates from the horizontal state to the vertical state is referred to as an opening operation, and an operation in which the support arm 420 rotates from the vertical state to the horizontal state is referred to as a closing operation.

Next, the configuration of the return drive unit 440 will be described.
The return drive unit 440 is a mechanism for rotating the blocking bar 430 rotated in the release direction T1 in the return direction T2 and returning it to the non-release state as power different from the power for opening and closing the blocking bar 430. Thus, as shown in FIGS. 21 and 22, it is integrally fixed to the lower portion of the support arm 420 in a horizontal state. As shown in FIGS. 23 and 24, the return drive unit 440 includes a return motor (rotary drive unit) 441 housed in a return drive unit main body 440a having a casing shape, and a positive motor of the return motor 441. A transmission mechanism 442 for transmitting the rotation to the release shaft 422 and a state detection unit 455 for detecting the non-release state or the release state of the blocking bar 430 are provided.

  The return motor 441 is a so-called servo motor that can arbitrarily control the rotation speed and the rotation angle, and the output shaft 441 a can rotate forward and backward based on a command from the control unit 490.

  The transmission mechanism 442 includes a first worm gear 443 that transmits the rotation of the return motor 441 to the release shaft 422 only when the blocking bar 430 rotates in the release direction T1, a first rotation shaft 444, and a second worm gear 445. The first spur gear 446, the second rotation shaft 447, the clutch mechanism 448, the second spur gear 451, and the third spur gear 452 are provided.

As shown in FIGS. 23 to 26, the first worm gear 443 is fixed to the tip of the output shaft 441a coaxially with the output shaft 441a, and a male screw that is twisted around the axis is formed on the outer peripheral surface thereof. ing.
The first rotating shaft 444 is an axis extending in the vertical direction of the return drive unit main body 440a when the support arm 420 is in a horizontal state (hereinafter simply referred to as the vertical direction in the description of the return drive unit 440). For example, it is provided so as to be rotatable about an axis via a bearing (not shown) arranged in the return drive unit main body 440a.

  The second worm gear 445 is a substantially disk-shaped member that is coaxially fixed to the first rotation shaft, and rotates integrally with the first rotation shaft 444. Gear teeth are formed on the outer peripheral surface of the second worm gear 445 so as to be screwed with the male screw of the first worm gear 443, whereby the first worm gear 443 and the second worm gear 445 are interlocked with each other around their respective axes. It is designed to rotate.

The first spur gear 446 is a substantially disk-shaped gear fixed coaxially to the first rotating shaft 444, and gear teeth are formed on the outer peripheral surface thereof. The first spur gear 446 is integrally fixed to the upper portion of the second worm gear 445, and thereby rotates around the axis line in conjunction with the second worm gear 445 and the first rotating shaft 444.
The second rotation shaft 447 is a shaft that extends in the vertical direction in parallel with the first rotation shaft 444, and can rotate around the axis via a bearing (not shown) disposed in the return drive unit main body 440a, for example. Is provided.

The clutch mechanism 448 includes a first gear 449 and a second gear 450 that are arranged coaxially with respect to the second rotation shaft 447.
The first gear 449 has a substantially disk shape that is coaxially and integrally fixed to the second rotation shaft 447, and is configured to rotate about the axis together with the second rotation shaft 447. Gear teeth are formed on the outer peripheral surface of the first gear 449, and the gear teeth mesh with the gear teeth of the first spur gear 446. As a result, the first gear 449 and the first spur gear 446 can be rotated in conjunction with each other around their respective axes.

  On the upper surface of the first gear 449, as shown in FIG. 25 (a), a pair of claw portions 449a having point symmetry of 180 ° about the axis so as to sandwich the axis of the first gear 449. , 449a. Each of the claw portions 449a and 449a has a cylindrical shape extending in parallel with the axis of the first gear 449.

As shown in FIGS. 23 and 24, the second gear 450 has a disk shape arranged so as to be relatively rotatable around the axis with respect to the second rotation shaft 447, and overlaps the upper portion of the first gear 449. Is arranged.
As shown in FIG. 25A, the second gear 450 is formed with a pair of grooves 450a and 450a penetrating in the thickness direction of the second gear 450. These groove portions 450a, 450a have an arc shape extending around the axis of the second gear 450, and are arranged so as to be 180 ° point-symmetric about the axis so as to sandwich the axis of the second gear 450. Has been.

  As shown in FIG. 25 (b), a pair of claw portions 449a and 449b of the first gear 449 are inserted into the groove portions 450a and 450a of the second gear 450 in a one-to-one relationship. Thereby, the first gear 449 and the second gear 450 can be relatively rotated around the axis line in accordance with the allowable movement range of the claw portions 449a and 449a in the groove portions 450a and 450a.

  The second spur gear 451 is a gear that is coaxially and relatively rotatable with respect to the second rotation shaft 447 and is integrally fixed to the upper portion of the second gear 450 in the support arm 420 in a horizontal state. Yes. As a result, the second spur gear 451 rotates integrally with the second gear 450. Further, gear teeth are formed on the outer peripheral surface of the second spur gear 451.

  The third spur gear 452 is a gear provided coaxially and integrally with the release shaft 422 below the release shaft 422 provided on the support arm 420, and can rotate in conjunction with the release shaft 422. It is said that. Further, gear teeth are formed on the outer peripheral surface of the third spur gear 452, and the gear teeth mesh with the gear teeth of the second spur gear 451. As a result, the second spur gear 451 and the third spur gear 452 rotate in conjunction with each other around their respective axes.

  Here, when the output shaft 441a of the return motor 441 is rotated forward by a command from the control unit, as shown in FIG. 26, the forward rotation of the output shaft 441a causes the first worm gear 443, the second worm gear 445 in the transmission mechanism 442, This is transmitted to the first gear 449 of the clutch mechanism 448 via the first spur gear 446. As a result, the first gear 449 and the claw portions 449a and 449a rotate 90 ° clockwise as shown in FIG. 27 from the initial position shown in FIG. Hereinafter, such an operation of the first gear 449 and the claw portions 449a and 449a is referred to as a normal rotation operation.

On the other hand, after the first gears 449 and 449 and the claw portions 449a and 449a are normally rotated from the initial positions, when the output shaft 441a of the return motor 441 is reversely rotated by a command from the control unit 490, the output shaft 441a is similar to the above. Is transmitted to the first gear 449 of the clutch mechanism 448 via the first worm gear 443, the second worm gear 445, and the first spur gear 446 in the transmission mechanism 442. As a result, the first gear 449 and the claw portions 449a and 449a rotate 90 ° counterclockwise in FIG. 27, that is, in the opposite direction to the normal rotation operation, and return to the initial position. Hereinafter, the operation of the first gear 449 and the claw portions 449a and 449a is referred to as reverse rotation operation.
As described above, the first gear 449 and the claw portions 449a and 449a reciprocately rotate in an angle range of 90 ° in accordance with the forward / reverse rotation of the output shaft 441a of the return motor 441.

Further, when the blocking bar 430 performs the release operation and changes from the non-release state to the release state, as shown in FIG. 28, the rotation in the release direction T1 of the release shaft 422 accompanying this release operation causes the third rotation in the transmission mechanism 442. This is transmitted to the second gear 450 via the spur gear 452 and the second spur gear 451. As a result, the second gear 450 rotates by 90 ° counterclockwise as shown in FIG. 29 from the initial position shown in FIG. Hereinafter, the operation of the second gear 450 is referred to as a release interlocking operation.
After the second gear 450 performs the release interlocking operation, as shown in FIG. 29, the claw portions 449a and 449a at the initial position of the first gear 449 are the end portions of the grooves 450a and 450a on the clockwise front side in FIG. It abuts on the abutting end portion 450b to be a part.

On the other hand, when the second gear 450 after the release interlocking operation rotates 90 ° opposite to the release interlocking operation, the rotation is applied to the release shaft 422 via the second spur gear 451 and the third spur gear 452 in the transmission mechanism 442. Communicated. As a result, the release shaft 422 rotates in the return direction T2. Along with this, the blocking bar 430 returns from the released state to the non-released state. Hereinafter, the operation of the second gear 450 is referred to as a return interlocking operation.
As described above, the second gear 450 and the blocking rod 430 are configured to interlock with each other, that is, the release interlocking operation of the second gear 450 and the releasing operation of the blocking rod 430 correspond to each other. The two gears 450 are interlocked with each other so that the return interlocking operation of the two gears 450 corresponds to the returning operation of the blocking bar 430.

The state detection unit 455 includes a detected disk 456 and a disk detection sensor 457.
The detected disk 456 is a substantially disk-shaped member as shown in FIGS. 24, 27, and 29, and is coaxially and integrally fixed to the upper surface of the second gear 450 in the clutch mechanism 448. The detected disk 456 has an outer diameter larger than the outer diameter of the second gear 450, and further includes a first slit 456a and a first slit 456a formed so as to be cut out radially inward from the outer peripheral edge. Two slits 456b are provided. The first slit 456a and the second slit 456b are arranged at an interval of 90 ° in the circumferential direction of the detected disk 456.

  The disk detection sensor 457 is a sensor held on the inner wall of the return drive unit main body 440a. For example, a distance sensor that can measure the distance to an object by irradiating a laser is employed. In this embodiment, the disk detection sensor 457 irradiates the laser along the vertical direction of the support arm 420 that is in a horizontal state with respect to the outer periphery of the detected disk 456. Thereby, according to the rotation angle of the detected disk 456, a case where the first slit 456a or the second slit 456b exists in the laser irradiation area and a case where the detected disk 456 exists in the irradiation area are detected. It is supposed to be.

  As shown in FIGS. 24 and 27, such a disk detection sensor 457 is provided in the first slit 456a when the blocking bar 430 is in a non-released state and the second gear 450 is in the initial position. In other words, the first slit 456a is located in the laser irradiation region of the disk detection sensor 457. In this case, the state detection unit 455 recognizes that the blocking bar 430 is in a non-release state.

  Then, as shown in FIG. 29, when the second gear 450 performs the release interlocking operation, the disk detection sensor 457 fixed to the second gear 450 is also rotated in accordance with this, so that the disk detection sensor 457 rotates. The second slit 456b exists in the laser irradiation region of the sensor 457. As described above, when the first slit 456a is initially positioned in the laser irradiation region of the disk detection sensor 457, the detection disk 456 rotates, so that the object positioned in the laser irradiation region becomes the detection disk 456. As such, when the second slit 456b is changed, the state detecting unit 455 recognizes that the blocking bar 430 has changed to the released state.

Further, when the second gear 450 performs the return interlocking operation, the disk detection sensor 457 fixed to the second gear 450 is also rotated along with this, so that the laser detection area of the disk detection sensor 457 is changed. There will be a first slit 456a. Thus, when the second slit 456b is initially positioned in the laser irradiation region of the disk detection sensor 457, the detection disk 456 rotates, so that the object positioned in the laser irradiation region becomes the detection disk 456. As such, when the first slit 456a is changed, the state detecting unit 455 recognizes that the blocking bar 430 has changed to the released state.
As described above, the state detection unit 455 detects whether the blocking bar 430 is in a non-release state or a release state.

In addition to the above configuration, the circuit breaker 410 of the present embodiment includes a release state holding unit 460, a non-release state holding unit 470, and an auxiliary return drive unit 480, as shown in FIGS. It may be provided.
The release state holding part 460 is a mechanism for holding the blocking bar 430 in the release state, and is provided on the upper surface of the tip of the support arm 420 in a horizontal state as shown in FIGS. 21 and 22.

Further, the non-release state holding portion 470 is a mechanism for holding the blocking bar 430 in the non-release state. As shown in FIGS. 21 and 22, the non-release state holding portion 470 is in a horizontal state and moves up and down on the arm body 21 of the support arm 20. A pair is provided.
Further, the auxiliary return drive unit 480 moves toward the return direction T2 with respect to the blocking bar 30 when the blocking bar 430 rotating in the return direction T2 reaches a predetermined position before reaching the non-release state. It has the role of imparting torque.

Next, the operation of the circuit breaker 410 of this embodiment will be described.
When the vehicle has not entered the vehicle traffic path R and the circuit breaker 410 is in a standby state, as shown in FIG. 21, the support arm 20 is in a horizontal state and the blocking bar 430 is in a non-release state. That is, the blocking bar 430 is in the blocking position S that is the home position.

  In this non-released state, the return drive unit 440 positions the first gear 449 and the second gear 450 of the clutch mechanism 448 in the initial state as shown in FIG. Further, the first slit 456a of the detected disk 456 is positioned in the laser irradiation region of the disk detection sensor 457 in the state detection means 455, and accordingly, the blocking bar 430 is in a non-release state. Has been detected.

When the vehicle enters the toll gate having the circuit breaker 410 in the standby state in this way, the control unit rotates the output shaft of the opening / closing motor forward based on the entry of the vehicle, thereby supporting arm 420. Then, the blocking rod 430 is rotated from the blocking position S to the permission position K. As a result, the circuit breaker 410 is allowed to pass through the vehicle.
On the other hand, when the vehicle exits from the toll gate, the control unit reversely rotates the output shaft of the opening / closing motor based on the exit of the vehicle, thereby blocking the support arm 420 and the blocking bar 430 from the permitted position K. Rotate to position S. As a result, the breaker 410 prevents the vehicle from passing.
When the vehicle that has entered the toll gate is an abnormal vehicle, the opening / closing motor is not driven, and the support arm 420 and the blocking bar 430 are blocked from passing through the vehicle.

Next, when the blocking bar 430 is in the released state after the release operation is completed, the returning operation for rotating the blocking bar 430 in the return direction T2 to return to the non-released state will be described.
This return operation is performed based on, for example, a release return command that is sent out by the operation of a toll gate staff when the blocking bar 430 after the release operation is in the release state.

When this release return command is input to the control unit, the control unit rotates the output shaft 441a of the return motor 441 in the return drive unit 440 in the normal direction, thereby causing the first gear 449 of the clutch mechanism 448 in the transmission mechanism 442 to rotate. Is rotated forward 90 ° around the axis.
At this time, as shown in FIG. 30, the contact end portions 450b and 450b of the grooves 450a and 450a of the second gear 450 are in contact with the front side in the rotation direction of the claws 449a and 449a of the first gear 449. The second gear 450 rotates in the same direction in conjunction with the forward rotation operation of the first gear 449. That is, the claw portions 449a and 449a of the first gear 449 press the contact end portions 450b and 450b of the groove portions 450a and 450a of the second gear 450, whereby the first gear 449 is interlocked with the forward rotation operation. The two gears 450 perform a return interlocking operation.

  When the second gear 450 performs the return interlocking operation in this manner, the rotation based on the return interlocking operation is transmitted to the release shaft 422 via the second spur gear 451 and the third spur gear 452, and the release shaft 422 is returned in the return direction. Rotate to T2. Accordingly, the blocking bar 430 supported by the release shaft 422 rotates in the return direction T2. When the blocking bar 430 reaches the released state, the biasing protrusion 473 of the non-released state holding part 470 engages with the recesses 432a and 432b of the base part 432, and the blocking bar 430 is held in the non-released state.

As described above, in the circuit breaker 410 according to the present embodiment, when the blocking bar 430 rotates in the release direction T1 due to the collision of the vehicle with the blocking bar 430, the blocking bar 430 is opened and closed separately. By driving the return drive unit 440 having power, the blocking bar 430 can be rotated in the return direction T2.
That is, only when the release shaft 422 is in the released state, the contact ends 450b and 450b of the grooves 450a and 450a of the second gear 450 abut on the claws 449a and 449a, so that the first gear 449 and the claw The forward rotation operation of the portions 449 a and 449 a is transmitted to the second gear 450. Thereby, the blocking bar 430 interlocked with the release shaft 422 can be rotated in the return direction T2.

As mentioned above, although embodiment of this invention was described in detail, unless it deviates from the technical idea of this invention, it is not limited to these, A some design change etc. are possible.
In the first, second and third embodiments, the opening / closing operation and the release operation of the blocking rod 30 have the same power. In the fourth embodiment, the opening / closing operation and the releasing operation of the blocking rod 430 are performed. However, the present invention is not limited to the configuration of the embodiment as long as the release operation and the opening / closing operation of the blocking rods 30 and 430 are possible, and other configurations may be adopted. Good. For example, for the first, second, and third embodiments, a configuration in which the power for the opening / closing operation and the release operation is separated may be adopted, and for the fourth embodiment, the power for the opening / closing operation and the release operation may be adopted. The same configuration may be adopted.
