Description

  The present invention provides a traffic control device such as ETC (registered trademark) installed near the entrance / exit of a toll road, provided with a lock mechanism for locking and releasing the release state, and a return mechanism for returning the opening / closing bar. It relates to a start controller.

  An ETC (registered trademark) lane at the entrance and exit of a toll road such as an expressway is provided with a start controller that informs the driver of permission or disapproval of vehicle traffic by opening and closing a bar-shaped opening and closing bar. In many start controllers, when a vehicle contacts or collides with an open / close bar in a closed position (vehicle passage is not permitted), the open / close bar is used to prevent serious damage to the vehicle or the start controller. Can be moved to a so-called release position (retracted position) by rotating in a substantially horizontal direction. In some start-up controllers, when a vehicle or the like comes in contact with an open / close bar other than the closed position, the open / close bar rotates from that position.

  For example, in Patent Document 1, the hinge pin 36 that rotatably attaches the blocking bar 34 to the support member 30 is tilted in the vehicle passing direction or the opposite side of the vehicle traveling path, and the blocking bar returned to the retracted position is returned. A gate opening and closing device for a vehicle that is intended to prevent rotation by utilizing a moment due to gravity is disclosed.

  In Patent Document 2, when the blocking rod 6 is rotated in the horizontal direction and moved to the retracted position, a passage provided with a blocking rod returning device that can return the blocking rod 6 to the vertical rotation state by a switch operation. A circuit breaker is disclosed.

  Further, Patent Document 3 discloses a support arm 12 that is provided so as to be rotatable between a closed position and an open position in accordance with the rotation of an opening / closing shaft that extends and rotates in a substantially horizontal direction, and can be rotated by the support arm 12. The release shaft 122 supported by the release shaft 122, the blocking rod 13 fixed to the release shaft 122 and provided so as to be rotatable to the normal position and the release position, and the blocking rod 13 in conjunction with the rotation of the support arm 12. A vehicle traffic breaker is disclosed that includes a guide portion 14 that guides the blocking bar 13 so as to rotate from the release position to the normal position.

JP 2005-68886 A JP 2011-58331 A JP 2011-256680 A

  In the normal operation of the devices as described in Patent Documents 1 and 2, the blocking bar (blocking rod) is cantilevered in a substantially horizontal state in the closed position, and is moved so that one end of the blocking bar jumps up in the open position. It becomes a state. On the other hand, when the vehicle collides with the blocking bar (blocking rod) in the closed position, the blocking rod (blocking rod) rotates in the horizontal direction and moves to the retracted position in order to reduce the impact. However, in the gate opening / closing device described in Patent Document 1, it is understood that the operation of returning the blocking rod moved to the retracted position to the original state needs to be performed manually, which is heavy on the operator and takes time to return. .

  In the invention described in Patent Document 2, the barrier rod that has moved to the retracted position can be automatically restored, but is in the retracted position in addition to the driving device 3 for performing a normal (vertical) opening / closing operation. A return device 5 is provided for pushing the blocking bar 6 back to the vertical rotation state. However, the return device 5 described in Patent Document 2 is provided at the side of the traffic barrier 1, and as shown in FIG. 1B and the like, the barrier 6 is rotated in the horizontal direction to perform the return operation. In this case, the barrier will interfere with the vehicle traffic space. For safety reasons, it is desirable to prevent any member from entering the vehicle traffic space during the return operation. As another conventional technique, there is an example in which the return device is provided inside an arm or bar holder that opens and closes. However, in that case, a motor and a complicated link mechanism are required, which is disadvantageous in terms of cost.

  In the vehicle traffic breaker described in Patent Document 3, since the blocking bar 13 is guided to the guide portion 14 when the support arm 12 is rotated, the blocking bar 13 is moved from the release position to the normal position without using a separate drive source. It is understood that it can return to. However, the guide portion is provided on the front surface of the main body 11 of the circuit breaker so as to protrude over a relatively wide range, so that the apparatus becomes large. Further, since the guide portion 14 contacts the support arm over the entire movable range (about 90 °) of the support arm 12, the blocking bar 13 is angularly displaced with respect to the support arm 12 immediately after the support arm 12 is rotated, As a result, the blocking rod 13 may enter the vehicle traffic space during the return operation.

  Therefore, the present invention provides a start controller having a return mechanism that can perform a return operation from the release position after releasing the release lock with a simple configuration and that does not allow the opening / closing bar to enter the vehicle passage space during the return operation. The purpose is to provide.

  In order to achieve the above object, the first invention of the present application is directed to a main body, an arm rotatably attached to a rotary drive shaft that rotates relative to the main body, and the rotary drive shaft with respect to the arm. A bar holder rotatably attached around a vertical release axis, and an open / close bar fixed at one end to the bar holder, the open / close bar extending substantially horizontally by driving the rotary drive shaft It is configured to be movable between a closed position that prevents passage of the vehicle and an open position that rotates vertically from the closed position to allow passage of the vehicle, and when the vehicle is in the closed position, In the start controller configured to rotate in a substantially horizontal direction around the release axis with respect to the arm and move to the release position, a lock mechanism for holding the open / close bar at the release position is provided in the arm. Provided A projecting member that is associated with the locking mechanism and that projects from the surface of the arm facing the main body so as to be displaceable with respect to the surface is provided. A convex portion is provided that abuts on the projecting member and displaces the projecting member when within the return operation rotation angle range, and the projecting member contacts the projecting portion while being displaced. A return arm unit having a push-up member is provided on the upper portion of the main body of the start controller, and the push-up member has the open / close bar at the release position and the arm. Is at a rotational angle position corresponding to the closed position, the bar holder is pushed up and pivoted with respect to the arm to return the open / close bar to the closed position. It is configured to provide a start control apparatus.

  According to a second invention, in the first invention, when the rotation angle position of the rotary drive shaft when the open / close bar is in the closed position is set to zero degrees, the arm has a rotation angle of 75 degrees to 90 degrees. Provided is a start controller in which the lock mechanism is unlocked when it is within range.

  According to a third invention, in the first or second invention, the push-up member is a roller attached to a revolving arm provided so as to be rotatable with respect to the main body of the return arm unit. Provide a controller.

  According to the present invention, the release mechanism can be released into the arm or bar holder by combining a lock mechanism that does not require electrical means using the rotational motion of the arm and a return arm unit with a simple structure provided at the top of the start controller. Therefore, it is unnecessary to provide a motor or the like for the vehicle, and it is possible to realize a start controller that is highly reliable as a whole and has a reduced cost.

  By restricting the unlocking operation of the lock mechanism when the rotation angle of the arm is in the range of 75 to 90 degrees, it is reliably prevented that the opening / closing bar moves inadvertently and enters the vehicle traffic space.

  By making the push-up member of the return arm unit a freely rotatable roller, the probability of damage or breakage of the bar holder can be reduced.

The unit is returned to the original state and the return operation is completed.

  FIG. 1 is an external perspective view showing a start controller 2 according to a preferred embodiment of the present invention. The start controller 2 includes a substantially rectangular parallelepiped main body 6 fixedly disposed on an installation surface 4 such as the ground, and a rotating shaft 8 that is substantially parallel to the installation surface 4 (generally substantially horizontal) on the side surface of the main body 6 on the vehicle entry side. The arm 10 is rotatably attached to the arm 10 and the opening / closing bar 12 is provided so as to be rotatable with respect to the arm 10 within a predetermined angle range. In the illustrated example, one end of the open / close bar 12 is fixed to the bar holder 14 and is supported in a so-called cantilever manner. The bar holder 14 is relative to the arm 10 with respect to the rotation shaft 16 perpendicular to the rotation shaft 8 of the arm 10. , And is attached so as to be rotatable within a rotation angle range of at least 90 °. In the present embodiment, it is assumed that the vehicle passes in the direction indicated by the arrow 18, and the rotating shaft 8 of the arm 10 is substantially parallel to the vehicle passing direction 18.

  The arm 10 is rotationally driven with respect to the main body 6 by a drive source (not shown) built in the main body 6. As a drive source of the arm 10, for example, various electric motors (not shown) can be used, but a servo motor capable of accurately controlling the rotation angle position of the arm 10 is preferable.

  In a normal opening / closing operation, the opening / closing bar 12 extends substantially horizontally as shown in FIG. 1A to prevent the vehicle from passing therethrough, and extends substantially vertically as shown in FIG. 1B. The arm 10 is moved in the vertical direction between the open positions where the passage of the arm 10 is permitted. More specifically, assuming that the rotation angle position of the arm 10 with respect to the main body 6 in the closed position in FIG. 1A is zero degree, the arm 10 in the open position shown in FIG. Rotate until it moves to a position that does not interfere with the movement. Usually, the rotation angle position of the arm in the open position is approximately 90 degrees, and more specifically, it is often set within a range of 80 degrees to 100 degrees. In this normal opening / closing operation, the rotational angle position of the bar holder 14 (opening / closing bar 12) with respect to the arm 10 does not change.

  Originally, the vehicle (not shown) traveling in the direction of the arrow 18 passes through the side of the start controller 2 when the open / close bar 12 is in the closed position (FIG. 1A). Although it must not be done, it may come into contact with the open / close bar 12 due to an excessive speed or carelessness of the driver. In such a case, in order to prevent serious damage to the vehicle or the start controller, as shown in FIG. 1 (c), the open / close bar 12 rotates about 90 degrees in the substantially horizontal direction with respect to the arm 10. Then, it moves to a so-called release position (retracted position). In other words, the bar holder 14 rotates about 90 degrees horizontally with respect to the arm 10 when a force of a predetermined value or more acts on the opening / closing bar 12 to retract the opening / closing bar 12 from the vehicle. The opening / closing bar 12 is held at the release position by a lock mechanism, which will be described later, so that the open / close bar 12 does not rotate (bounce back) from the release position and re-contact with the vehicle.

  Next, a return mechanism for returning the open / close bar 12 from the release position shown in FIG. As shown in FIG. 2, the surface 20 of the arm 10 facing the main body 6 has a mounting hole 22 that engages with the rotation shaft 8 (see FIG. 3B) of the main body 6, whereby the arm 10 is As the rotary shaft 8 rotates, it rotates relative to the main body 6. On the other hand, the bar holder 14 that fixes and holds the opening / closing bar 12 is pivotally attached to the arm 8 so as to be rotatable about the rotation shaft 16, and at least the opening / closing bar 12 is substantially perpendicular to the direction of the rotation shaft 8. Rotates between the extended normal angular position (state shown in FIG. 2) and the release position (state shown in FIG. 1C) where the open / close bar 12 extends substantially parallel to the direction of the rotation shaft 8 (ie, at least about 90 degrees). Is possible. Further, the arm 10 has a protruding member 24 that protrudes from the surface 20 toward the main body 6 side.

  Next, the operation until the arm 10 is rotated and the bar holder 14 is moved to the vicinity of the return arm unit 42 described later will be described with reference to FIGS. FIG. 3 (a) is an external side view of the start controller 2 when the open / close bar 12 is in the release position (FIG. 1 (c)) in the vehicle traveling direction (arrow 18). These are figures which show the AA cross section of Fig.3 (a). The protruding member 24 shown in FIG. 2 is configured to be movable in a direction in which the protruding member 24 comes into contact with and separates from the main body 6 (up and down direction in FIG. 3B) as shown in FIG. The projecting member 24 preferably has a curved surface at the contact portion with the convex portion 40 in view of displacement on the convex portion 40 on the main body 6 to be described later, and is formed as a disk-shaped member in the illustrated example. However, it may be a spherical or hemispherical member.

  The protruding member 24 is associated with a locking mechanism using a cam and a latch as shown in a broken line in FIG. 3B, and specifically, can rotate around the first pivot 26 inside the arm 10. Is connected to one end of a first latch 28 provided in the first latch 28. The other end opposite to one end of the first latch 28 with respect to the first pivot 26 is adapted to lock a link member 30 arranged so as to extend in the longitudinal direction inside the arm 10. The pin-shaped member 32 provided on the link member 30 is locked. The link member 30 has a long hole 34 that engages with the first pivot 26, so that the inside of the arm 10 can be displaced in the longitudinal direction. Further, the link member 30 is configured so that the bar holder 14 can be rotated around the rotation axis 16 with respect to the arm 10 by the displacement. Specifically, one end of the link member 30 is pivotally attached to a tab-like member 36 that is substantially integral with the bar holder 14 via a second pivot 38. However, as shown in FIG. 3B, while the first latch 28 is locking the pin-like member 32, the link member 30 is displaced so as to rotate the bar holder 14 with respect to the arm 10 (FIG. 3). (B) cannot be displaced to the right), so the open / close bar 12 is held in the release position.

  4A is an external side view of the start controller 2 when the arm 10 is rotated toward an angular position corresponding to a normal open position, as viewed in the vehicle traveling direction (arrow 18). (B) is a figure which shows the BB cross section of Fig.4 (a). As shown in FIG. 4A, when the arm 10 rotates with respect to the main body 6 (for example, 80 degrees from the state of FIG. 3) while the open / close bar 12 is in the release position, FIG. ), The protruding member 24 provided on the arm 10 is engaged so as to ride on the convex portion 40 provided on the side surface of the main body 6. The convex portion 40 may have any shape as long as it can displace the projecting member 24 with respect to the arm 10 until the arm 10 reaches the angular position corresponding to the open position. It is preferable to use a slope for operation. Due to the displacement of the projecting member 24, the first latch 28 connected to the projecting member 24 rotates about the first pivot 26 (counterclockwise in the illustrated example), and the first latch 28 moves from the pin-shaped member 32 of the link member 30. The locking mechanism that separates and holds the open / close bar 12 in the release position is released. However, in this state, the bar holder 14 (opening / closing bar 12) is in a state of being rotatable with respect to the arm 10, but the opening / closing bar 12 is maintained at the release position by its own weight or the like.

  The above-described unlocking operation is performed at any rotation angle position from the state of FIG. 3 (the rotation angle of the arm 10 is zero degrees) to the state of FIG. 4 (the rotation angle of the arm 10 is 90 degrees). However, it is preferable in terms of safety to keep the locked state as long as possible. Therefore, it is desirable that the unlocking operation starts at a rotation angle of 75 to 80 degrees of the arm 10 and is completed slightly before the rotation angle (90 degrees in the illustrated example) corresponding to the closed position (for example, 85 to 88 degrees).

  FIG. 5A is an external side view of the start controller 2 viewed in the vehicle traveling direction (arrow 18) when a return operation (described later) using the return arm unit 42 is completed, and FIG. These are figures which show the CC cross section of Fig.5 (a). FIG. 5 shows the time when the return operation is completed, but the positional relationship between the bar holder 14 and the arm 10 is the same as that during a normal opening / closing operation. Here, during normal operation, it is necessary to prevent the opening / closing bar 12 from easily moving to the release position unless an impact such as a vehicle coming into contact with the opening / closing bar 12 is applied. Therefore, in the present embodiment, as shown in the broken line in FIG. 5B, a latching mechanism that holds the bar holder 14 in the normal position is provided. Specifically, the second latch 44 is provided on the tab-like member 36 to which the link member 30 is connected, and the second latch 44 is hooked to the stopper member 46 when the opening / closing bar 12 (bar holder 14) is in the normal position. . In the illustrated example, the stopper member 46 is a pin-like member extending between two plate-like members 48 having substantially the same shape and arranged in parallel. The plate-like member 48 and the pin-like member 46 are integrally formed in the arm 10. It is rotatable around the third pivot 50 provided. The plate-like member 48 is urged in the rotating direction (clockwise direction) of the bar holder 14 by a spring 52, and further, a notch 54 provided in the plate-like member 48 and a protruding portion (in the illustrated example) fixed inside the arm 10. In this case, the pin-like member 56 is normally engaged with the pin-like member 56 so as to be held at the position shown in FIG.

  Here, when the open / close bar 12 is in the closed position (therefore, the positional relationship between the arm 10 and the bar holder 14 is the same as that shown in FIG. 7B), a vehicle or the like contacts and a load of a certain level acts on the open / close bar 12. Then, a force to rotate around the rotation shaft 16 toward the release position (counterclockwise) acts on the tab-like member 36 of the bar holder 14, and the force is plate-like against the urging force of the spring 52. The member 48 is rotated around the third pivot 50, whereby the pin-like member 46 and the second latch 44 are not latched, and the bar holder 14 and the open / close bar 12 are moved to the release position as shown in FIG. 4B. To do. By appropriately setting the spring constant of the spring 52, it is possible to set how much force is applied to the open / close bar 12 when the open / close bar 12 moves to the release position.

  FIG. 6 is a diagram showing a schematic configuration of a return arm unit 42 for returning the open / close bar 12 from the release position. For clarity, in FIGS. 6 and 7, the arm 10 and the bar holder 14 are simply shown, and the open / close bar 12 is not shown. The return arm unit 42 includes a unit main body 60 disposed on the upper portion (upper surface) of the main body 6 of the start controller 2, a revolving arm 62 provided with one end pivotable with respect to the unit main body 60, And a push-up member 64 attached to the other end. The push-up member 64 is configured to be able to contact the bar holder 14 when the open / close bar 12 is in the release position and the arm 10 is in the angular position corresponding to the open position (state of FIG. 4), as described below. The bar holder 14 can be pushed up so that the bar holder 14 rotates with respect to the arm 10 and the open / close bar 12 returns from the release position.

  A drive mechanism (not shown) for turning the turning arm 62 is built in the unit main body 60. The drive mechanism includes, for example, a motor and a speed reducer, and is configured such that the push-up member 64 can transmit torque necessary for rotating the bar holder 14 to the swing arm. Further, there are no particular restrictions on the specific shapes and materials of the swivel arm 62 and the push-up member 64, but the swivel axis 68 of the swivel arm 62 is substantially parallel to the swivel axis 16 of the bar holder 14, for example, From the viewpoint of preventing damage to the bar holder 14 and the like, it is preferable that the pressing member 64 is also a roller extending substantially parallel to the rotation shaft 16, and the roller is freely rotatable with respect to the turning arm 62. As the material of the roller 64, for example, rubber, resin, or metal such as aluminum can be used, and any material may be used as long as it is suitable for free rotation.

  Next, FIGS. 7A to 7E are views for explaining the operation of the return arm unit 42. First, from the state shown in FIG. 1 (c), as shown in FIG. 7 (a) corresponding to the state of FIG. 4, the arm 10 is moved to the normal open position with the open / close bar (bar holder 14) in the release position. It rotates to the corresponding angular position (approximately 90 degrees in the illustrated example). In the state of FIG. 7A, as described with reference to FIG. 4, the lock mechanism is released and the bar holder 14 can be rotated from the release position to the normal position with respect to the arm 10. .

  Next, as shown in FIG. 7B, the return arm unit 42 is activated, the turning arm 62 is turned by the drive mechanism described above, and the push-up member 64 pushes up the bar holder 14 accordingly. Further, the turning arm 62 turns to push up the bar holder 14 (FIG. 7C), and the bar holder 14 returns to the normal rotation angle position with respect to the arm 10 (FIG. 7D). Then, the operation of the swing arm 62 is temporarily stopped.

  Finally, as shown in FIG. 7E, the turning arm 62 is turned in the reverse direction to return to the initial position, and the return operation is completed. In this state, the arm 10 and the bar holder 14 are returned to the normal open position (corresponding to FIG. 1B).

  As shown in FIG. 6, the return arm unit 42 only needs to have a function of rotating the bar holder 14 with respect to the arm 10, so that the return arm unit 42 can be configured compactly at the top of the start controller 2. Maintenance is also easy. Therefore, in the present invention, it is not necessary to provide a release release motor or the like in the arm 10 or the bar holder 14, and the cost can be reduced as a whole.

  Although not shown, in the start controller 2 according to the present invention, the detection means for detecting that the opening / closing bar 12 has moved to the release position, or the detection means for detecting that the opening / closing bar 12 has moved to the release position is detected. When it does, the alarm means which issues an alarm to the worker who exists in the booth away from the start control machine 2, etc. can be provided. The return operation described above may be performed by an operator who has received an alarm sending an instruction to the return arm unit 42 by remote control from within the booth or the like, and the detection result of the detection means is automatically returned to the return arm unit. The return arm unit 42 may automatically perform the return operation in response to the result.

  In the above-described embodiment, the opening / closing bar 12 is connected to the arm 10 via the bar holder 14, and the push-up member 64 of the return arm unit 42 is structured to push up the bar holder 14, but the start controller is omitted from the bar holder 14. It is also possible to adopt the configuration described above. In this case, the push-up member 64 of the return arm unit 42 pushes up the opening / closing bar 12 and rotates with respect to the arm 10.
