Description

  The present invention relates to a gate device that restricts the passage of a vehicle or the like at a toll gate on a highway or a toll road, or a parking lot, and a gate control system including the gate device. The present invention relates to a gate device that automatically returns and a gate control system including the gate device.

  2. Description of the Related Art Conventionally, gate devices are installed, for example, at ETC (Electronic Toll Collection System) gates at toll gates on expressways and toll roads and at entrances and exits of toll parking lots. The gate device regulates the passage of the vehicle by lying down on the gate bar (in a closed state) and blocking the roadway. Normally, the vehicle does not collide with a gate bar that blocks the road. However, for example, when a vehicle that has forgotten to attach an ETC card to the ETC on-board unit passes through the ETC gate, or a vehicle that enters the parking lot exits without waiting for the gate bar to open due to intention or negligence. For example, the vehicle may collide with the gate bar. Some gate devices rotate (release) the gate bar in the vehicle traveling direction when the vehicle collides in order to prevent the gate bar from being damaged by the vehicle collision. Some gate devices return a released gate bar automatically or remotely.

  Further, a technique for holding the gate bar released due to a vehicle collision or the like in that state is disclosed in, for example, Patent Document 1 or the like. In the gate device of Patent Document 1, when the blocking bar is released in any state, the blocking bar holder is opposite to the release direction by the plunger shaft inserted into the connecting member contacting the bottom surface of the blocking bar holder. Rebound in the direction (non-release direction) is prevented.

  By the way, there is a case where a reverse lane is provided at an entrance / exit of an expressway. In the reverse lane, the operation direction (vehicle traveling direction) is switched between the forward direction and the reverse direction, and the operation direction is switched appropriately according to the time zone or the congestion situation during the holiday season etc. With this, traffic jams can be resolved.

  For example, in Patent Document 2, for the purpose of quickly and surely switching the operation state of the reverse lane, as a roadside device on the reverse lane, a first vehicle detector provided on one end side and provided on the other end side When the second vehicle detector is provided and an instruction to operate in the forward mode is received, the queue management is performed with the first vehicle detector as the entry detector and the second vehicle detector as the exit detector. When the roadside device is controlled and, on the other hand, an instruction to operate in the reverse mode is received, the roadside device is set so that the first vehicle detector is the exit detector and the second vehicle detector is the entrance detector. A reverse lane control system for switching operation states is disclosed.

JP 2011-252309 A Japanese Patent Laying-Open No. 2015-041347

  When a gate equipped with an automatic release return mechanism is installed in a reverse lane where the traveling direction can be switched between the forward direction and the reverse direction, the direction in which the gate bar is released differs depending on the vehicle collision. It was necessary to install a direction gate. Therefore, the installation cost increases, and as a result, a large number of reverse lanes cannot be installed, making it difficult to operate the lanes flexibly.

  The present invention has been made in view of the above-described problems, for example, and the problem of the present invention is that it is suitably installed in a reverse lane while being equipped with an automatic release return mechanism, and contributes to an increase in the reverse lane. Another object of the present invention is to provide a gate device and a gate control system that can flexibly operate a lane.

  In order to solve the above-described problem, a first gate device of the present invention is a gate device that restricts the passage of a moving body on a roadway, and is disposed above a main body portion and the main body portion in a vertical direction. A rotation part supported by the main body so as to be rotatable around an extending vertical rotation axis, and one end side of the rotation part being rotatable about a horizontal rotation axis extending in a horizontal direction. A gate bar base portion whose other end side extends in a direction intersecting the horizontal rotation axis, and a release portion in which an intermediate portion extends to the other end side of the gate bar base portion in a direction intersecting with the extension direction of the gate bar base portion. A gate bar supported so as to be rotatable around a moving axis, one end side is detachably held on one end side of the gate bar base, and the other end side extends in the same direction as the gate bar base; and the gate bar base Gate bar A gate bar driving unit that rotates around the horizontal rotation axis between a recumbent position where the part and the gate bar lie down and a standing position where the gate bar base part and the gate bar stand up; When regulating, the position of the rotating part is determined so that the gate bar in the recumbent position blocks the roadway, and one end side of the gate bar is detached from one end side of the gate bar base part, and the gate bar is released. When the release operation of rotating around the rotating shaft in the moving direction of the moving body is performed, the rotating portion is rotated so as to follow the rotation of the gate bar, and one end side of the gate bar is moved to the gate bar base portion. The position of the rotating portion is determined so as to approach or contact one end side and to hold one end side of the gate bar to one end side of the gate bar base portion. The gate bar drive unit and the rotation drive unit are arranged such that the gate bar base unit and the gate bar are arranged on one side of the rotation unit in the traveling direction of the roadway, When operating in the traveling direction change mode, the rotating portion, the gate bar base portion, and the gate bar are driven, and the gate bar base portion and the gate bar are disposed on the other side of the rotating portion in the traveling direction of the roadway. It is characterized by making it.

  According to the first gate device of the present invention, even when the traveling direction of the roadway is switched between the forward direction and the reverse direction, the passage of the vehicle can be regulated corresponding to each traveling direction, The gate bar can be released in a direction corresponding to the traveling direction. Therefore, it is not necessary to arrange two gate devices for the forward direction and the reverse direction, and the installation cost can be greatly reduced. For this reason, since a gate apparatus is installed suitably in a reverse lane, it contributes to the increase in the lane which can change the advancing direction, and enables flexible operation of a lane.

  In order to solve the above-described problem, the second gate device of the present invention is the above-described first gate device of the present invention, wherein the gate bar driving unit and the rotation driving unit operate in the traveling direction changing mode. In this case, after the gate bar is erected once, the turning part is turned in a direction in which the gate bar base part approaches the roadway to change the direction by 180 degrees.

  According to the second gate device of the present invention, in the traveling direction change mode, even if the turning portion is rotated so that the gate bar base portion approaches the road side, the gate bar base portion stands up, so Even if the vehicle does not protrude greatly and the vehicle is stopped on the roadway, the traveling direction change mode can be operated safely. Further, since the rotation range of the rotation drive unit is within 180 degrees including the release return operation, the structure of the mechanism and the detection switch is not complicated and can be configured easily.

  In order to solve the above-described problem, a first gate control system of the present invention includes the first or second gate device of the present invention described above, and a remote control unit that remotely operates the gate device, The remote operation unit is configured to be capable of selecting the traveling direction switching mode for the gate device in accordance with an operator's selection operation.

  According to the first gate control system of the present invention, a clerk or the like uses a roadway in a forward direction by a simple method of selecting a traveling direction change mode of the gate device by remote operation using a remote control unit. The gate device can be automatically switched to cope with the use in the reverse direction.

  According to the present invention, the gate device and the gate control system are preferably installed in the reverse lane while being equipped with an automatic release return mechanism, contributing to an increase in the reverse lane and being able to flexibly operate the lane. .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiments are preferable specific examples of the present invention and disclose various preferable techniques, but the technical scope of the present invention is not limited to these embodiments.

  First, a gate device 1 according to an embodiment of the present invention will be described. As shown in FIG. 1 and the like, the gate device 1 is a concrete formed along the road 2 along the road 2 at the gate of a toll gate of a highway or a toll road or an entrance of a toll parking lot. It is installed on the island 3 which is a made platform. The gate device 1 regulates the passage of a gate of a vehicle (moving body) traveling on the roadway 2 by opening and closing a gate bar 16 described later. It is desirable that the surface of the gate device 1 on the side of the road 2 and the curb portion of the island 3 on the side of the road 2 are as close as possible, and the closer the approach, the shorter the length of the gate bar 16 is. it can.

  In this embodiment, for convenience of explanation, when the gate is viewed from a point on the roadway 2 before passing through the gate, the front side is “front”, the far side (back side) is “rear”, and the right side is “right”. The left side is defined as “left”, the upper side as “upper”, and the lower side as “lower”. Hereinafter, when the direction is described in the present embodiment, this definition is assumed. That is, the traveling direction (forward direction) of the vehicle when the roadway 2 is normally used is a direction in which the vehicle travels backward from the gate device 1 after approaching the gate device 1 from the front of the gate device 1. On the other hand, the traveling direction (reverse direction) of the vehicle when the lane 2 is used as a reverse lane is a direction in which the vehicle travels forward from the gate device 1 after approaching the gate device 1 from behind the gate device 1.

  The gate device 1 is orthogonal to the main body 11, a rotation part 13 provided so as to be rotatable above the main body 11 via a vertical rotation shaft 12 extending in the vertical direction, and the vertical rotation shaft 12. A gate bar base 15 is rotatably provided on the rotary part 13 via a horizontal rotary shaft 14, and a gate bar 16 is detachably attached to the gate bar base 15 so that a release operation described later can be performed.

  In the present embodiment, the gate device 1 arranges the gate bar base 15 and the gate bar 16 so as to restrict forward traffic of the vehicle, while operating in the traveling direction change mode (reverse mode), the reverse direction of the vehicle The gate bar base 15 and the gate bar 16 are arranged so as to restrict traffic. In the following, a normal configuration and operation that are not in the traveling direction change mode will be described except for the case where the traveling direction change mode is specified.

  In addition, the position of the rotation part 13 when the horizontal rotation shaft 14 is positioned so as to extend in the front-rear direction is referred to as a “vehicle path blocking position” (FIGS. 1, 2 (1) and (2), FIG. 4 (1) and (2), see FIG. 5 (2)). Further, in the operation of returning the released gate bar 16 (release return operation), the position of the rotating unit 13 when the gate bar 16 is held on the gate bar base 15 (positioned so that the horizontal rotating shaft 14 extends in the left-right direction). The position of the rotating portion 13 at that time) is referred to as a “gate bar pick-up position” (see FIGS. 3 (2), 4 (4), and 5 (1)). Below, each direction in description of each part, such as the rotation part 13, is shown on the basis of the position where a vehicle can be blocked unless otherwise specified.

  In addition, when the turning portion 13 is in a position where the road can be blocked (normal position), the horizontal turning shaft 14 is turned to cause the gate bar base portion 15 and the gate bar 16 to lie down and stand up. The operation for blocking / opening is referred to as “road opening / closing operation” (or gate opening / closing operation). At this time, the position at which the gate bar base 15 and the gate bar 16 lie down is referred to as a “horizontal position” (see FIGS. 1 and 2 (1) two-dot chain line). The position at which the gate bar base 15 and the gate bar 16 stand up is referred to as the “standing position”. (Refer to FIG. 2 (1) solid line, FIG. 5 (2) solid line). Below, each direction in description of the gate bar base 15 and the gate bar 16 etc. is shown on the basis of the recumbent position unless otherwise specified.

  First, the main body 11 will be described. The main body 11 includes a main body casing 21 formed in a rectangular column shape, and the main body casing 21 is fixed on the island 3 via the main body base 4. An opening / closing lid (not shown) is attached to the rear surface of the main body casing 21 so as to be opened and closed. When the opening / closing lid is opened, almost the entire rear surface of the main body housing 21 opens. Yes.

  The main body 11 includes a vertical rotation shaft 12 and a rotation driving unit 22 that rotates the vertical rotation shaft 12 inside the main body housing 21. The vertical rotation shaft 12 is disposed substantially at the center in the main body casing 21, and the upper end of the vertical rotation shaft 12 is exposed to the outside through an opening formed at the approximate center of the upper surface of the main body casing 21. The rotating part 13 can be connected.

  The rotation drive unit 22 includes a rotation drive motor 56 (see FIG. 6) described later. The rotation drive unit 22 rotates the vertical rotation shaft 12 in the horizontal direction, thereby moving the rotation unit 13 connected to the vertical rotation shaft 12 together with the horizontal rotation shaft 14, the gate bar base portion 15, and the gate bar 16. It can be rotated in the horizontal direction. For example, the rotation drive unit 22 rotates the vertical rotation shaft 12 when the gate bar 16 that has been released is returned to the state before the release operation, that is, the original state in which the road opening and closing operation is possible.

  In addition, the rotation drive unit 22 is normally configured such that the gate bar base 15 and the gate bar 16 are disposed on the front side (one side) of the rotation unit 13 in the front-rear direction (the traveling direction of the roadway 2). On the other hand, when operating in the traveling direction change mode, the gate bar base 15 and the gate bar 16 are disposed on the rear side (the other side) of the rotating unit 13 in the front-rear direction (the traveling direction of the roadway 2). Thus, the arrangement of the rotating unit 13 is controlled.

  A first stopper 23 that supports the gate bar 16 that has been released is provided on the left side of the rear surface of the main body casing 21. The first stopper 23 is erected on the island 3 at a position spaced rearward from the main body casing 21. A second stopper 24 stands on the island 3 on the opposite side of the main body casing 21 in the front-rear direction from the first stopper 23, that is, at a position spaced forward from the main body casing 21. Has been. Further, the first stopper 23 and the second stopper 24 are positioned slightly outside the rotation trajectory of the tip of the locking mechanism 45 on one end side of the gate bar 16 during the release operation described later, In a position where they do not come into contact.

  Next, the rotation unit 13 will be described. The rotation unit 13 includes a box-shaped rotation housing 31 formed in a rectangular column shape. When the gate device 1 is viewed from above, it is desirable that the rectangular outer shape of the rotating housing 31 is substantially the same as the rectangular outer shape of the main body housing 21. Connected to the vertical rotation shaft 12 at the center. An opening / closing door (not shown) is attached to the rear surface of the rotating casing 31 so that the opening / closing door can be opened and closed so that substantially the entire rear surface of the rotating casing 31 opens when the opening / closing door is opened. It has become.

  The rotating unit 13 includes a horizontal rotating shaft 14 and a gate bar driving unit 32 that drives the horizontal rotating shaft 14 together with the gate bar base 15 and the gate bar 16 inside the rotating housing 31. The tip of the horizontal rotation shaft 14 is exposed to the outside through an opening formed in the front surface of the rotation housing 31 and can be connected to the gate bar base 15. A flange 33 is fixed to the distal end of the horizontal rotation shaft 14 so that the gate bar base portion 15 is detachably attached with a screw or the like.

  The gate bar drive unit 32 includes a gate bar drive motor 52 (see FIG. 6) described later. The gate bar drive unit 32 moves the horizontal rotation shaft 14 to the gate bar base 15 and the gate bar 16 while the rotation unit 13 is in a position where the road can be blocked and the horizontal rotation shaft 14 extends in the front-rear direction. In addition, the roadway opening and closing operation can be performed by rotating it together (see the broken line arrow in FIG. 2 (1)). For example, the gate bar drive unit 32 is configured such that the gate bar base 15 and the gate bar 16 are in the “recumbent position” when the road 2 is blocked, and the gate bar base 15 and the gate bar 16 are in the “standing position” when the road 2 is opened. The horizontal rotation shaft 14 is rotated so that “ The “standing position” of the gate bar base 15 and the gate bar 16 may be a position that sufficiently opens the roadway 2 (gate). For example, the position where the gate bar base 15 and the gate bar 16 are vertically upright or However, when operating in the traveling direction change mode, the substantially upright position is referred to as the “standing position”.

  Further, the gate bar drive unit 32 is normally arranged with the gate bar base 15 and the gate bar 16 so as to restrict the passage of the vehicle on the front side (one side) of the rotating unit 13 in the front-rear direction (the traveling direction of the roadway 2). On the other hand, when operating in the advancing direction switching mode, the gate bar base 15 and the rear side (the advancing direction of the vehicle path 2) are restricted to the passage of the vehicle on the rear side (the other side) with respect to the rotating portion 13. The arrangement of the gate bars 16 is controlled.

  Next, the gate bar base 15 and the gate bar 16 will be described. The gate bar base portion 15 is a long member formed in a U-shaped cross-section with an opening on the front side, and has a shape that fits one end side of the gate bar 16. The rear surface of the gate bar base portion 15 on one end side (right side) in the longitudinal direction is attached to the horizontal rotation shaft 14 and can be rotated with respect to the rotation portion 13 in accordance with the rotation of the horizontal rotation shaft 14. Yes. On the other hand, the other end side (left side) in the longitudinal direction of the gate bar base portion 15 extends in a direction intersecting with the horizontal rotation shaft 14 (a direction orthogonal to the horizontal rotation shaft 14 in this embodiment). A release rotation shaft 41 extending in the short direction (vertical direction) is provided on the other end side of the gate bar base portion 15. A holding portion spring 42 is attached to the bottom of the gate bar base portion 15 (see FIGS. 4 (2) to (4)).

  The gate bar 16 is formed in a long shape, and has a length that can block the roadway 2 when the passage of the vehicle is restricted by one gate device 1. Note that when two gate devices 1L and 1R are arranged on the left and right sides of the roadway 2 as in a gate control system 71 described later, the gate bar 16 is formed relatively short. The gate bar 16 includes a gate bar holding portion 43 provided on one end side (right side) in the longitudinal direction and a gate bar main body 44 attached to the gate bar holding portion 43 and extending to the other end side (left side) in the longitudinal direction. The gate bar main body 44 is formed by covering the other end side of a core portion made of a lightweight material, for example, an aluminum hollow pipe, with a cushioning material made of foamed urethane or the like. In order to improve visibility from a driver or the like, a laminate such as red and white stripes may be applied to the outer surface portion of the cushioning material constituting the gate bar main body 44.

  The gate bar 16 is attached to the gate bar base 15 so that the gate bar holding portion 43 is fitted to the gate bar base 15. At this time, the other end side in the longitudinal direction of the gate bar holding portion 43 located at the intermediate portion of the gate bar 16 is rotatably supported by the release rotation shaft 41 of the gate bar base portion 15. Thereby, the gate bar 16 can be rotated around the release rotation shaft 41 with respect to the gate bar holding portion 43.

  One end side of the gate bar 16 is detachably held on one end side of the gate bar base portion 15. Specifically, a locking mechanism 45 is provided on one end side of the gate bar base portion 15 and one end side of the gate bar 16, and the locking mechanism 45 causes one end side of the gate bar base portion 15 and one end side of the gate bar 16 to be connected. They are detachably locked to each other. The gate bar base portion 15 and the gate bar 16 are locked by the locking mechanism 45 so as to extend in a straight line and are integrally fixed, and the vehicle can be opened and closed. When the gate bar base portion 15 and the gate bar 16 are unlocked by the locking mechanism 45, the integrated fixing is released, and the gate bar 16 rotates around the release rotation shaft 41 with respect to the gate bar base portion 15. In the present embodiment, this turning operation is referred to as “release operation”, and the direction in which the gate bar 16 rotates around the release turning shaft 41 by the releasing operation (the gate device 1 disposed on the island 3 on the right side of the roadway 2). In this case, the other end in the longitudinal direction of the gate bar 16 is the direction toward the vehicle traveling direction and is the clockwise direction when viewed from above (refer to FIG. 4 (2), broken line arrow). When the gate device 1 operates in the traveling direction change mode, the counterclockwise direction when viewed from above is the release direction.

  The locking mechanism 45 has a holding force enough to maintain the locking between the gate bar base 15 and the gate bar 16 (gate bar holding portion 43) even when a force such as vibration or wind pressure is applied due to the road opening / closing operation. . On the other hand, the locking mechanism 45 is configured so that the gate bar base 15 and the gate bar 16 (gate bar holding portion 43) are unlocked by a force greater than the holding force, for example, an external force applied when the vehicle collides with the gate bar 16. Composed. The locking mechanism 45 is configured to lock the gate bar base 15 and the gate bar 16 when the released gate bar 16 rotates in the non-release direction and is fitted to the gate bar base 15 by a predetermined pressing force. Have

  Although not shown, a torsion spring as a release biasing portion is provided in the vicinity of the release rotation shaft 41 in the gate bar base portion 15. The torsion spring applies a biasing force to the gate bar 16 so as to promote the rotation of the gate bar 16 in the release direction during the release operation.

  Next, a release operation and a release return operation in the gate device 1 will be described with reference to FIGS. 2 to 5 show the release operation and release return operation of the gate device 1. Here, the “release return operation” is an operation for returning the gate bar 16 that has been released to a state before the release operation, that is, to the original state in which the road opening and closing operation is possible.

  First, the release operation of the gate device 1 will be described. In the gate device 1, normally, as shown in FIGS. 2 (1) and 4 (1), the rotating unit 13 is in a position where the road can be blocked, and the horizontal rotating shaft 14 extends in the front-rear direction. The gate bar base 15 and the gate bar 16 can be opened and closed.

  In a normal state, the vehicle does not collide with the gate bar 16 blocking the roadway 2. However, for example, when the vehicle that has forgotten to attach the ETC card to the ETC (Electronic Toll Collection System) vehicle-mounted device passes through the gate of the ETC, the vehicle is placed on the gate bar 16 blocking the roadway 2. May collide.

  When a vehicle traveling on the road 2 collides with the gate bar 16 blocking the road 2, the vehicle collides with the other end of the gate bar 16 (the other end of the gate bar main body 44). When the vehicle collides with the gate bar 16 in this way, the locking mechanism 45 is unlocked by an external force applied to the other end side of the gate bar 16 due to the collision, and from one end side of the gate bar base portion 15 to one end side of the gate bar 16 (gate bar One end side of the holding portion 43 is detached. As shown in FIGS. 2 (2) and 4 (2), the gate bar 16 rotates in the vehicle traveling direction (release direction) about the release rotation shaft 41 (see the broken line arrow in FIG. 4 (2)). ).

  At this time, when the force applied to the other end side of the gate bar 16 due to the collision is small, the gate bar 16 has a force generated by the collision and a torsion spring (release urging unit, not shown) provided in the vicinity of the release rotating shaft 41. ), And stops by hitting the first stopper 23 with a relatively weak force. Thus, according to the torsion spring, the gate bar 16 that performs the release operation can be surely and quickly reached the first stopper 23, and the gate bar 16 is in contact with the first stopper 23 and maintained in a stopped state. Can do. On the other hand, when the force applied to the other end side of the gate bar 16 due to the collision is large, the gate bar 16 rotates vigorously due to the force caused by the collision and hits the first stopper 23 with a relatively strong force. The shock received by the stopper 23 is absorbed by the cushioning material of the first stopper 23 (or the cushioning property due to the bending of the first stopper 23 itself). In this way, for example, the gate bar 16 rotates about 90 degrees clockwise (release direction) when viewed from above and stops, and the direction of the gate bar 16 becomes almost parallel to the roadway 2 to complete the release. It becomes a state.

  Next, the release return operation of the gate device 1 will be described. The release operation of the gate bar 16 as described above is detected by a release detection switch 60 (see FIG. 6), which will be described later, and in response to this, the release operation is automatically started immediately by the control unit 51 (see FIG. 6). Is done. In the release return operation, first, as shown in FIG. 3 (1) or FIG. 4 (3), the rotation drive unit 22 rotates the vertical rotation shaft 12, and the rotation unit 13 releases the gate bar 16. It is rotated so as to follow or follow the rotation. For example, the rotation drive unit 22 rotates the rotation unit 13 approximately 90 degrees clockwise (release direction) when viewed from above from the position where the roadway can be blocked to the gate bar reception position (see FIGS. 3A and 3B). 2) See dashed arrow).

  At this time, the gate bar 16 also rotates in the clockwise direction as viewed from above as the rotation unit 13 rotates. Since the gate bar 16 is in contact with the first stopper 23, the gate bar 16 is moved backward while the contact with the first stopper 23 is maintained while the rotating portion 13 rotates in the clockwise direction. (In addition, when the gate apparatus 1 operates in the traveling direction change mode, the gate 13 is slid forward because the rotating unit 13 rotates counterclockwise as viewed from above.) become). Then, the gate bar 16 rotates around the release rotation shaft 41 in the non-release direction with the contact portion with the first stopper 23 as a fulcrum, and one end side of the gate bar 16 (one end side of the gate bar holding portion 43) is The gate bar base portion 15 gradually approaches one end side.

  3 (1) or 4 (3), the other end side of the gate bar 16 moves slightly in the direction away from the roadway 2 while the rotating portion 13 rotates, and the direction of the gate bar 16 However, if the other end of the gate bar 16 interferes with another device installed on the island 3 at this time, the main body of the first stopper 23 The distance from 11 is made longer, and the portion close to the other end of the gate bar 16 is configured to abut against the first stopper 23. Thereby, since the amount by which the other end side of the gate bar 16 moves in the direction away from the roadway 2 can be reduced, it is possible to prevent the other end of the gate bar 16 from interfering with other devices.

  3 (2) and 4 (4), when the turning portion 13 turns to reach the gate bar reception position, one end side of the gate bar 16 (one end side of the gate bar holding portion 43) is the gate bar. The one end side of the gate bar base 15 and the one end side of the gate bar 16 are pressed in the clockwise direction when viewed from above by the force of the rotation driving unit 22 rotating the rotation unit 13 after contacting the one end side of the base unit 15. The Further, one end side of the gate bar 16 receives an elastic force from the holding portion spring 42 at the bottom of the gate bar base portion 15. At this time, the force of the rotation driving unit 22 and the force of the holding unit spring 42 which are opposite to each other act on the one end side of the gate bar base portion 15 and the one end side of the gate bar 16, so Pressed strongly. As a result, the locking mechanism 45 provided on one end side of the gate bar base portion 15 and one end side of the gate bar 16 is securely locked to each other. By this locking, the gate bar base 15 and the gate bar 16 are integrally fixed so that both face the same direction.

  In this way, when the turning unit 13 is turned to the gate bar receiving position and the one end side of the released gate bar 16 is locked (held) to the one end side of the gate bar base 15, the turning drive unit 22 is The rotation of the rotation unit 13 is stopped.

  Subsequently, as shown in FIG. 5A, the gate bar driving unit 32 rotates the horizontal rotation shaft 14, and the gate bar base portion 15 and the gate bar 16 are clockwise when viewed from the front end side of the horizontal rotation shaft 14. (See FIG. 5 (1) dashed arrow). At this time, the direction of the integrally fixed gate bar base 15 and the gate bar 16 remains parallel to the roadway 2. When the gate bar base 15 and the gate bar 16 that rotate upward reach the standing position, the gate bar drive unit 32 stops the rotation of the horizontal rotation shaft 14.

  Thereafter, as shown in FIG. 5 (2), the rotation drive unit 22 rotates the rotation unit 13 in a direction (non-release direction) opposite to the traveling direction (release direction) of the vehicle (FIG. 5 (2)). ) See dashed arrows). Then, when the rotation unit 13 reaches the position where the road can be blocked, the rotation drive unit 22 stops the rotation of the rotation unit 13. For example, the rotating unit 13 rotates approximately 90 degrees counterclockwise (non-release direction) when viewed from above and reaches the roadway blocking position. Thus, when the rotating part 13 reaches the road blocking position, the position of the gate bar 16 is the same as the position when the road 2 is opened in the road opening / closing operation. Alternatively, the release return operation may be completed after the gate bar 16 is rotated counterclockwise as viewed from the front end side of the horizontal rotation shaft 14 to the recumbent position. In the case where the release return operation is completed after the gate bar 16 is rotated to the recumbent position, it is determined whether or not there is a vehicle passing through the gate for safety before the gate bar 16 is rotated. Only when there is no vehicle passing through the gate, the gate bar 16 is rotated to the recumbent position.

  Next, the electrical configuration of the gate device 1 will be described with reference to FIG. FIG. 6 shows a configuration for electrically controlling the operation of the gate device 1, and further shows an electrical configuration of a gate control system 71 described later provided with the gate device 1.

  As shown in FIG. 6, the gate device 1 includes a control unit 51 for overall control of the gate device 1, a gate bar drive motor 52 that rotates the gate bar base 15, and the gate bar base 15 or the gate bar 16 reaches the recumbent position. A first recumbent position detection switch 53 as a limit detection switch for detecting the occurrence of a failure, a standing position detection switch 54 for detecting that the gate bar base 15 or the gate bar 16 has reached the standing position, A second recumbent position detection switch 55 as a limit detection switch for detecting that the recumbent position has been reached (in the mode), a revolving drive motor 56 for revolving the revolving unit 13, and the revolving unit 13 blocking the road. A first cut-off position detection switch 57 as a limit detection switch for detecting the arrival at the possible position; As a limit detection switch for detecting the arrival position detection switch 58 for detecting that the vehicle has reached the gate bar reception position, and for detecting that the rotation unit 13 has reached the reverse direction (in the traveling direction changing mode) Switching between the second blocking position detection switch 59, the release detection switch 60 for detecting the establishment / release of the integrated fixing of the gate bar base 15 and the gate bar 16, and the control program for the right installation and the control program for the left installation A setting operation unit 61 that enables communication and a communication unit 62 that communicates with the roadway control device 80 and the like are provided.

  The control unit 51 is provided in the main body casing 21 and includes, for example, a CPU (Central Processing Unit), a memory, and the like. The memory controls a road opening / closing operation and a release return operation of the gate device 1. A control program is stored.

  Each of the gate bar drive motor 52 and the rotation drive motor 56 is a DC motor, for example. The release detection switch 60 is mounted in, for example, the shaft hole of the horizontal rotation shaft 14 and is turned off when the gate bar base 15 and the gate bar holding portion 43 are sufficiently approached or contacted, and turned on when the two are separated. Become. The setting operation unit 61 is, for example, a dip switch, and is provided in the main body casing 21. The communication unit 62 is provided in the main body housing 21 and receives vehicle data transmitted from the ETC antenna to the road control device 80 from the road control device 80 when the gate device 1 is installed at the ETC gate, for example. To do. Further, the communication unit 62 is connected to a management PC 81 to be described later via the roadway control device 80. When the communication unit 62 receives an operation direction change mode operation instruction from the management PC 81, the control unit 51 The dynamic driving unit 22 and the gate bar driving unit 32 are operated in the traveling direction changing mode.

  Next, the control of each part by the control unit 51 in the release return operation of the gate bar 16 that has been released as described above in the gate device 1 will be described with reference to the flowchart of FIG. Below, in the gate apparatus 1 installed in the right side of the roadway 2, the example which the control part 51 controls release return operation | movement with the control program for right installation is demonstrated.

  First, in the gate device 1, when the vehicle collides with the other end side of the gate bar 16 during the opening / closing operation of the roadway or when the gate bar 16 is in the recumbent position and shuts off the roadway 2, The gate bar 16 is released from the integral fixing with the gate bar 16 and rotated in the release direction. When the integrated fixing of the gate bar base 15 and the gate bar 16 is released, the release detection switch 60 is turned on (step S1: YES).

  When the release detection switch 60 is turned on, the control unit 51 drives the rotation drive motor 56 to rotate clockwise as viewed from above (step S2). By the rotation of the rotation drive motor 56 in the clockwise direction, the rotation unit 13 at the position where the road can be blocked rotates in the clockwise direction as viewed from above, that is, the traveling direction of the vehicle (the release direction of the gate bar 16). To turn.

  When the turning unit 13 reaches the gate bar pick-up position, the pick-up position detection switch 58 is turned on (step S3: YES). As described above, when the rotating portion 13 reaches the gate bar receiving position, the gate bar 16 is locked to the gate bar base portion 15 as described above, and the fixed fixation is established between the two, and the release detection switch 60 is turned off. (Step S4: YES). Immediately after this, the control part 51 stops the rotation drive motor 56 (step S5).

  Subsequently, the control unit 51 rotates the gate bar drive motor 52 in the clockwise direction when viewed from the front end side of the horizontal rotation shaft 14 (step S6). As the gate bar drive motor 52 rotates in the clockwise direction, the gate bar base 15 and the gate bar 16 in the recumbent position rotate in the clockwise direction as viewed from the front end side of the horizontal rotation shaft 14, that is, rotate toward the standing position. Move. When the gate bar base 15 and the gate bar 16 reach the standing position, the standing position detection switch 54 is turned on (step S7: YES). Immediately after this, the control part 51 stops the gate bar drive motor 52 (step S8).

  Subsequently, the control unit 51 rotates the rotation drive motor 56 in the counterclockwise direction when viewed from above (step S9). When the rotation drive motor 56 is rotated in the counterclockwise direction, the rotation unit 13 at the gate bar receiving position rotates counterclockwise as viewed from above, that is, the vehicle traveling direction (the release direction of the gate bar 16). ) And rotate in the opposite direction. And if the rotation part 13 reaches | attains a vehicle road interruption | blocking possible position, the 1st interruption | blocking position detection switch 57 will be set to ON (step S10: YES). Immediately after this, the control part 51 stops the rotation drive motor 56 (step S11).

  Subsequently, the control unit 51 determines whether or not the roadway 2 can be blocked (step S12). For example, when the control unit 51 receives a signal indicating that the vehicle cannot be blocked or is approaching the vehicle from the road control device 80, the control unit 51 determines that the vehicle cannot be blocked. If the signal is not received, the controller 51 can block the vehicle. Is determined.

  When it is determined that the roadway 2 can be blocked (step S12: YES), the control unit 51 rotates the gate bar drive motor 52 in the counterclockwise direction when viewed from the front end side of the horizontal rotation shaft 14 (step S13). ). Due to the counterclockwise rotation of the gate bar drive motor 52, the gate bar base 15 and the gate bar 16 in the standing position rotate counterclockwise as viewed from the front end side of the horizontal rotation shaft 14, that is, toward the recumbent position. Rotate. Subsequently, when the gate bar base 15 and the gate bar 16 reach the recumbent position, the first recumbent position detection switch 53 is turned on (step S14: YES). Immediately after this, the control unit 51 stops the gate bar drive motor 52 (step S15). Thereby, the release return operation is completed.

  Next, the gate control system 71 according to the embodiment of the present invention will be described. This gate control system 71 is applied, for example, to a gate of a roadway 2 such as an ETC vehicle lane on an expressway or a toll road, a common lane for ETC vehicles and non-ETC vehicles, or a non-ETC vehicle lane. is there.

  As shown in FIG. 8, the gate control system 71 includes a gate device 1 (left gate device 1L, right gate device 1R) on each of the left and right islands 3 (3L, 3R) of the roadway 2. Then, the gates 16 of the left gate device 1L and the right gate device 1R are both opened so that the vehicle 86 can pass. Since the right gate device 1R has the same configuration as the gate device 1 described above and is controlled by a control program for right installation, detailed description thereof is omitted. The left gate device 1L has a configuration that is symmetrical to the right gate device 1R across the roadway 2 and is controlled by a control program for left installation. The rotation direction and the like are symmetric with respect to the right gate device 1R, but basically the same arrangement, movement direction, rotation direction, and the like, and thus detailed description thereof is omitted.

  The gate control system 71 includes a first vehicle sensor 72, a forward ETC antenna 73, a second vehicle sensor 74, gate devices 1L and 1R, a camera 75, a third vehicle sensor 76, in order from the gate entrance side. An ETC antenna 77 for the reverse direction and a fourth vehicle sensor 78 are provided. Furthermore, although the gate control system 71 includes the road control device 80, the road control device 80 may be located at other positions on the left and right islands 3L or 3R, or at other positions other than the islands 3L and 3R. Good. As shown in FIG. 6, the road control device 80 is communicably connected to the communication unit 62 of the gate devices 1L and 1R, and further includes a first vehicle sensor 72, a forward ETC antenna 73, and a second vehicle sensor. 74, the third vehicle sensor 76, the reverse direction ETC antenna 77, and the fourth vehicle sensor 78 are also communicably connected.

  Furthermore, the gate control system 71 includes a management PC 81 (remote operation unit) and a monitor 82 for managing the system. The management PC 81 and the monitor 82 are installed, for example, in a monitoring booth 83 where staff members of a toll booth etc. reside, and the management PC 81 is connected to the roadway control device 80 so as to be communicable (see FIG. 6). The monitoring booth 83 may be provided in the vicinity of the island 3L or 3R, but may be provided at a position away from the islands 3L and 3R as long as it can be monitored remotely.

  The first vehicle sensor 72 detects a vehicle 86 entering the forward entrance of the gate, and the second vehicle sensor 74 detects the vehicle 86 traveling forward through the gate. The third vehicle sensor 76 detects a vehicle 86 that exits in the forward direction from the exit of the gate. On the other hand, for a vehicle traveling in the reverse direction to the gate, the fourth vehicle sensor 78 is replaced by the first vehicle sensor 72, and the third vehicle sensor 76 is replaced by the second vehicle sensor 74 instead of the second vehicle sensor 74. 74 is controlled to operate in place of the third vehicle sensor 76. The first vehicle sensor 72, the second vehicle sensor 74, the third vehicle sensor 76, and the fourth vehicle sensor 78 are, for example, left and right light emitting units that emit infrared light and light receiving units that receive emitted infrared light. Arranged on each of the islands 3L and 3R to detect the presence of the vehicle 86 in the detection area across the road 2 across the left and right islands 3L and 3R by detecting the light receiving state of the light receiving unit. Is done. Alternatively, the first vehicle sensor 72, the second vehicle sensor 74, the third vehicle sensor 76, and the fourth vehicle sensor 78 may be configured by a laser area sensor that scans a detection area. The first vehicle sensor 72 also has a function of detecting the height of the vehicle 86 traveling in the forward direction, and the fourth vehicle sensor 78 also has a function of detecting the height of the vehicle traveling in the reverse direction.

  The vehicle ETC antenna 73 traveling in the forward direction is installed, for example, on a gantry 84 (a gate column) that spans the left and right islands 3L and 3R so as to be positioned above the roadway 2. The ETC antenna 73 communicates (hereinafter referred to as ETC communication) with an ETC vehicle-mounted device (not shown) mounted on a vehicle 86 that passes through the road 2, so that the ETC such as the vehicle type of the vehicle 86 and the expiration date of the ETC card, etc. Information is acquired and transmitted to the road control device 80. The ETC communication operation between the ETC antenna 73 and the ETC vehicle-mounted device or the road control device 80 is performed at an extremely high speed. On the other hand, for a vehicle traveling in the reverse direction, an ETC antenna 77 for the reverse direction is used instead of the ETC antenna 73, and the ETC antenna 77 is also mounted on the left and right islands 3L and 3R. It is installed on the portal column. Note that two ETC antennas 73 and 77 may communicate with the vehicle in progress, and may interpolate data. Further, any one unit may be used in both the forward direction and the reverse direction.

  The camera 75 is installed on the right island 3R, for example, and captures the behavior of the vehicle 86 passing on the roadway 2, the driver of the vehicle 86, and the passenger.

  The roadway control device 80 integrally controls each part of the gate control system 71 connected to be communicable as described above. The road control device 80 basically opens the gate devices 1L and 1R according to the ETC communication result in the ETC antenna 73 in the forward direction, and the gate device according to the detection result in the third vehicle sensor 76. 1L and 1R are closed. For example, when the vehicle path control device 80 allows the vehicle 86 to pass according to the ETC communication result of the ETC antenna 73, the gate bar 16 is normally rotated from the recumbent position to the standing position to cancel the road block by the gate bar 16. Thus, the gate devices 1L and 1R are controlled.

  The management PC 81 is a computer used by a toll gate staff to manage the gate control system 71, and has a function of monitoring and remotely operating each device via a lane control device 80 connected to be communicable. . The management PC 81 is configured to be able to select the movement direction change mode operation of the gate devices 1L and 1R according to the selection operation of an operator such as an attendant, and the gate direction change mode is selected for the gate devices 1L and 1R. If it is, the direction change mode operation in the direction opposite to the current direction is automatically performed.

  The monitor 82 is connected to the management PC 81 to display the management status, and is connected to the camera 75 and connected to the camera 75, and the vehicle 86 on the road 2 taken by the camera 75, the driver of the vehicle 86, and passengers Images and videos can be displayed in a monitorable manner. In addition, the monitor 82 displays each imaging | photography result, when each of the some lane 2 is equipped with the some camera 75. FIG.

  Next, the opening operation and closing operation of the gate device 1R in the gate control system 71 will be described with reference to the flowchart of FIG. Here, unless otherwise specified, the operation and determination of each unit are performed by the road control device 80. Note that the opening operation and the closing operation of the gate device 1L are the same as those of the gate device 1R, and thus the description thereof is omitted.

  First, in the gate control system 71, the vehicle entering the gate is monitored by the first vehicle sensor 72 (step S21), and when the vehicle detection of the first vehicle sensor 72 is turned on (step S21: YES), the ETC The antenna 73 performs ETC communication with the ETC vehicle-mounted device of the vehicle 86 in order to acquire ETC information (step S22). At substantially the same time, the second vehicle sensor 74 monitors the vehicle 86 passing through the gate (step S23), the vehicle detection of the second vehicle sensor 74 is turned on, and the vehicle detection of the first vehicle sensor 72 is turned off. Then, since it can be determined that the vehicle 86 is passing, the process proceeds to an ETC communication result determination process (step S24).

  In the determination process of the ETC communication result (step S24), the road control device 80 can check the ETC communication result from the ETC antenna 73 against various data recorded in advance in the road control device 80, and can pass therethrough. It is determined whether the vehicle is an ETC vehicle. An ETC vehicle that can be passed is an ETC vehicle that is properly equipped with a valid ETC card, and is an ETC vehicle that can collect tolls at the exit of an expressway. If it is determined that the vehicle is an ETC vehicle that can pass (step S24: YES), the operation proceeds to the clockwise rotation operation (step S25) of the gate bar drive motor 52 as the gate opening operation.

  In the gate opening operation, the control unit 51 of the gate device 1R drives the gate bar drive motor 52 to rotate the horizontal rotation shaft 14, thereby rotating the gate bar base 15 and the gate bar 16 from the recumbent position to the standing position. . Next, in step S26, it is monitored whether the standing position detection switch 54 is turned on. When the standing position detection switch 54 is turned on, the process proceeds to step S27 and the gate bar drive motor 52 is immediately stopped. At this time, since the rotation drive motor 56 is not driven, the vertical rotation shaft 12 does not rotate, and the rotation unit 13 remains stopped. As a result, the ETC vehicle that can pass through can pass through the opened gate device 1R in a non-stop manner. Thereafter, the vehicle 86 exiting the gate is monitored by the third vehicle sensor 76 (step S28). When the vehicle detection of the third vehicle sensor 76 is turned on and then turned off (step S28: YES), the vehicle 86 is turned on. Therefore, as the gate closing operation, the operation shifts to the counterclockwise rotation operation (step S29) of the gate bar drive motor 52.

  The gate closing operation is the reverse of the above gate opening operation, and the control unit 51 of the gate device 1R drives the gate bar drive motor 52 to rotate the horizontal rotation shaft 14, whereby the gate bar base 15 And the gate bar 16 is rotated from the standing position to the recumbent position. Then, in step S30, it is monitored whether the first recumbent position detection switch 53 is turned on. If turned on, the process proceeds to step S31 and the gate bar drive motor 52 is immediately stopped. At this time, since the rotation drive motor 56 is not driven, the vertical rotation shaft 12 does not rotate, and the rotation unit 13 remains stopped. When the gate device 1R is thus closed, the flow for one vehicle 86 is completed.

  In the above ETC communication result determination process (step S24), if it is determined that the vehicle is not an ETC vehicle for some reason, or if it is determined that the vehicle cannot pass normally (that is, it is determined that the vehicle cannot pass ETC). In the case) (step S24: NO), the road control device 80 notifies the monitoring booth 83 of the arrival of the vehicle that cannot pass the ETC (step S32), and does not shift to the gate opening operation (step S25). The passage of the vehicle is restricted by the gate bar 16 at the position.

  In the monitoring booth 83, information indicating the arrival of a vehicle that cannot pass ETC is displayed on the screen of the monitor 82 or the management PC 81. Further, the ETC non-passable vehicle is photographed by the camera 75, and its video and image are displayed on the monitor 82 of the monitoring booth 83. For example, if an ETC non-passable vehicle does not stop, it collides with the gate bar 16 and the gate bar 16 performs a release operation. Therefore, the above-described release return operation (see FIG. 7) is performed. At this time, the clerk can visually check the management PC 81 or the monitor 82 and confirm the ETC non-passable vehicle colliding with the gate bar 16.

  On the other hand, an ETC non-passable vehicle may stop just before the gate bar 16. At this time, the attendant can visually check the management PC 81 or the monitor 82 to confirm the stopped ETC non-passable vehicle.

  At this time, since the clerk needs to move the vehicle that cannot pass the ETC from the gate in order to move the vehicle that cannot pass the ETC to another place such as a refuge where predetermined measures such as toll collection are performed, the management PC 81 Remote operation using is started (step S33: YES). In addition, before performing the opening operation of the gate device 1R, the attendant may guide the action after the opening operation to the driver of the vehicle that cannot pass through the speaker using the management PC 81 through a speaker (not shown). Well, for example, it can be instructed that there is a shelter at the end of the exit and that it should stop at that shelter.

  By the way, in highway toll booths, there are reverse lanes that can be used for both up and down lanes, for example, switching between up lanes and down lanes depending on the time of day or during busy seasons such as seasons and leisure seasons. Therefore, the lane may be operated flexibly. FIG. 8 shows a gate control system 71 in which the lane 2 is a reverse lane, and gate devices 1L and 1R are arranged on the left and right islands 3L and 3R, respectively, in the approximate center of the lane 2 in the front-rear direction. FIG. 8 shows a forward direction in which the vehicle 86 travels in the front-rear direction. This roadway is used when congestion is expected to occur in the oncoming lane in view of surrounding traffic conditions. After blocking 2 (blocked), the gate devices 1L and 1R are operated in the traveling direction change mode, so that the traveling direction of the roadway 2 can be reversed.

  The operation of the traveling direction change mode (reverse mode), which is a feature of the present invention, will be described along the flowchart of FIG. 10 based on the explanatory views of FIGS. FIG. 10 is a flowchart illustrating an operation in the traveling direction switching mode of the gate device according to the embodiment of the present invention. FIG. 11 is a perspective view for explaining the operation in the traveling direction switching mode of the gate device according to the embodiment of the present invention. Further, FIG. 12 is a plan view for explaining the operation in the traveling direction change mode of the gate device according to the embodiment of the present invention. 10 to 12 show an operation of changing the road 2 that has been set in the forward direction to the forward direction in the reverse direction.

  At the time before the operation in the traveling direction change mode is started, the gate devices 1L and 1R have the gate bar base 15 and the gate bar 16 in the front-rear direction (the roadway) as shown in FIGS. 11 (1) and 12 (1). 2 in the traveling direction), the front side (one side) of the rotating unit 13 is in a lying state. Then, a tollgate or the like operates the management PC 81 to remotely operate the gate devices 1L and 1R via the roadway control device 80, and selects the traveling direction change mode for the gate devices 1L and 1R. The operation in the traveling direction change mode is started in the gate devices 1L and 1R. Hereinafter, the operation of the gate device 1L will be described. Since the operation of the gate device 1L is the same as that of the gate device 1R, description thereof will be omitted.

  In the traveling direction switching mode, first, the gate bar driving unit 32 drives the gate bar driving motor 52 to rotate the gate bar base 15 or the gate bar 16 in the clockwise direction when viewed from the front end side of the horizontal rotation shaft 14 (step S41). The standing position detection switch 54 is monitored (step S42). Then, as shown in FIGS. 11 (2) and 12 (2), when the gate bar base 15 or the gate bar 16 reaches the standing position and the standing position detection switch 54 is turned on (step S42: Yes), the gate bar is driven. The unit 32 stops the gate bar drive motor 52 (step S43).

  Next, the rotation drive unit 22 drives the rotation drive motor 56 to rotate the rotation unit 13 in the clockwise direction when viewed from above (step S44), and monitors the second cutoff position detection switch 59. (Step S45). FIG. 11 (3) shows a state in which the rotating unit 13 is rotated by approximately 45 degrees, and FIG. 12 (3) shows a state in which the rotating unit 13 is rotated by approximately 90 degrees. Then, as shown in FIGS. 11 (4) and 12 (4), when the rotation unit 13 rotates approximately 180 degrees, the second cutoff position detection switch 59 is turned on (step S45: Yes), and the rotation is performed. The drive unit 22 stops the rotation drive motor 56 (step S46).

  Subsequently, the gate bar driving unit 32 drives the gate bar driving motor 52 to rotate the gate bar base 15 or the gate bar 16 in the clockwise direction when viewed from the front end side of the horizontal rotation shaft 14 (step S47), while the second horizontal beam The position detection switch 55 is monitored (step S48). Then, as shown in FIGS. 11 (5) and 12 (5), when the gate bar base 15 or the gate bar 16 reaches the recumbent position in the reverse direction and the second recumbent position detection switch 55 is turned on (step S48). : Yes), the gate bar drive unit 32 stops the gate bar drive motor 52 (step S49).

  Thereby, the preparation of the gate devices 1L and 1R when the traveling direction of the lane 2 as the reverse lane is reversed is completed. At this time, although detailed description is omitted, the detection logic of the first vehicle sensor 72, the second vehicle sensor 74, the third vehicle sensor 76, and the fourth vehicle sensor 78, and the ETC antennas 73 and 77 by the road control device 80. Preparation of physical barriers etc. that open the lane progress indicator lamp (not shown) (switching of indications that allow passage or no passage), the lane restriction gate (not shown), etc., and guide to the reverse lane After the arrangement, the gate control in the reverse direction of the reverse lane is started.

  As described above, according to the present embodiment, the gate device 1 that restricts the passage of the vehicle (moving body) on the roadway 2 includes the main body portion 11, the rotating portion 13, the gate bar base portion 15, and the gate bar 16. And a gate bar driving unit 32 and a rotation driving unit 22. The rotation unit 13 is disposed above the main body unit 11 and supported by the main body unit 11 so as to be rotatable around a vertical rotation shaft 12 extending in the vertical direction. One end side of the gate bar base 15 is supported by the turning portion 13 so as to be rotatable around a horizontal turning shaft 14 extending in the horizontal direction, and the other end side is extended in a direction intersecting the horizontal turning shaft 14. Yes. The gate bar 16 is supported on the other end side of the gate bar base portion 15 so that the gate bar 16 can rotate around a release rotation shaft 41 extending in a direction intersecting with the extending direction of the gate bar base portion 15, and one end side is supported on the gate bar base portion 15. The other end side extends in the same direction as the gate bar base portion 15. The gate bar driving unit 32 moves the horizontal rotation shaft 14 between the horizontal position where the gate bar base 15 and the gate bar 16 lie down and the standing position where the gate bar base 15 and the gate bar 16 stand up. Rotate around. The rotation drive unit 22 determines the position of the rotation unit 13 so that the gate bar 16 in the recumbent position blocks the road 2 when restricting the passage of the vehicle, and one end side of the gate bar 16 is one end of the gate bar base unit 15. When the gate bar 16 is released from the side and performs a release operation in which the gate bar 16 rotates about the release rotation shaft 41 in the moving direction of the vehicle, the rotation unit 13 is rotated so as to follow the rotation of the gate bar 16. One end side of 16 is brought close to or in contact with one end side of the gate bar base 15, and the position of the rotating portion is determined so that one end side of the gate bar 16 is held on one end side of the gate bar base 15. The gate bar drive unit 32 and the rotation drive unit 22 arrange the gate bar base unit 15 and the gate bar 16 on one side (front side) of the rotation unit 13 in the traveling direction (front-rear direction) of the roadway 2 while changing the traveling direction. When operating in the mode, the rotation unit 13, the gate bar base 15 and the gate bar 16 are driven so that the gate bar base 15 and the gate bar 16 are on the other side of the rotation unit 13 in the traveling direction (front-rear direction) of the roadway 2 ( Place it on the rear side.

  With such a configuration, in the gate device 1 according to the present embodiment of the present invention, even when the traveling direction of the roadway 2 is switched between the forward direction and the reverse direction, the vehicle passes in accordance with each traveling direction. In addition to being able to regulate, the gate bar can be released in a direction corresponding to each traveling direction. Therefore, it is not necessary to arrange two gate devices for the forward direction and the reverse direction, and the installation cost can be greatly reduced. For this reason, since the gate apparatus 1 is installed suitably in a reverse lane, it contributes to the increase in the lane which can change the advancing direction, and enables flexible operation of a lane.

  In the gate device 1 according to the present embodiment, when the gate bar driving unit 32 and the rotation driving unit 22 operate in the traveling direction changing mode, the gate bar base 15 is moved to the roadway 2 after the gate bar 16 is once raised. The turning unit 13 is turned in the approaching direction to change the direction by 180 degrees.

  With such a configuration, even in the traveling direction changing mode, even if the turning portion 13 is turned so that the gate bar base portion 15 approaches the road side, the gate bar base portion 15 is standing up so that the gate bar base portion 15 stands up and protrudes greatly. Even if the vehicle is stopped on the roadway, the traveling direction change mode can be operated safely. Further, since the rotation range of the rotation drive unit 22 is within 180 degrees including the release return operation, the structure of the mechanism and the detection switch is not complicated and can be configured easily.

  In addition, the gate control system 71 according to the present embodiment includes the gate device 1 described above and a management PC 81 (remote operation unit) that remotely operates the gate device 1, and the management PC 81 responds to the selection operation of the operator. Thus, the gate device 1 is configured to be able to select the traveling direction change mode.

  With such a configuration, when a staff member or the like uses the roadway 2 in the forward direction and in the reverse direction with a simple method of selecting the traveling direction change mode of the gate device 1 by remote operation using the management PC 81. Thus, the gate device 1 can be automatically switched to cope with it.

  As described above, according to the gate device 1 and the gate control system 71 according to the embodiment of the present invention, in the reverse lane where the traveling direction is switched between the forward direction and the reverse direction, the automatic release is performed in any traveling direction. A gate equipped with a mechanism capable of returning can be installed. Thereby, there is no need to install different gates for the forward direction and the reverse direction, and the installation cost can be reduced. Therefore, as a result, a large number of reverse lanes can be installed, and flexible operation of the lanes becomes possible.

  In the present embodiment, in order for the gate device 1 to detect the phases of the rotating unit 13, the gate bar base 15, and the gate bar 16, the first recumbent position detection switch 53, the standing position detection switch 54, and the second recumbent reed. Although the structure provided with the position detection switch 55, the 1st interruption | blocking position detection switch 57, the pick-up position detection switch 58, and the 2nd interruption | blocking position detection switch 59 was demonstrated, it is not limited to this structure. For example, in another embodiment, if an encoder that can detect the phase of the gate bar base 15 and the gate bar 16 (phase of the gate bar drive motor 52) and a sensor that detects the standing position are provided, the gate bar base 15 and the gate bar 16 are provided. The detailed speed control of the operation of the (gate bar drive motor 52) over approximately 180 degrees is possible. Further, for example, in another embodiment, the position of three positions of 0 degrees, 90 degrees, and 180 degrees of the rotation unit 13 (the rotation drive motor 56) is detected by the first blocking position detection switch 57 and the pick-up position. You may determine by the combination with the detection switch 58 or the 2nd interruption | blocking position detection switch 59. FIG.

  In the above, in the operation of the gate device 1 according to the present embodiment, the gate device 1R installed on the right island 3R of the roadway 2 whose forward direction is the traveling direction will be described, and the gate device 1L installed on the left island 1L will be described. However, as with the gate device 1R, the gate device 1L can easily control the left and right synchronous operations by simply changing the logic of each switch and the rotation direction of each motor. In addition, the detailed description of the operation of returning the gate devices 1L and 1R set so that the reverse direction of the roadway 2 is set as the traveling direction in the traveling direction change mode is omitted in the forward direction. It is only necessary to reversely rotate each part in the traveling direction switching mode, and the control can be easily performed in the same manner.

  Furthermore, in this embodiment, the rotation drive unit 22 is operated so that the rotation range of the rotation unit 13 (the rotation drive motor 56) changes from 0 degrees, 90 degrees, and 180 degrees, but the direction of travel changes. In the mode, the rotation drive unit 22 may rotate the rotation unit 13 (the rotation drive motor 56) in the direction opposite to the operation to the welcome position. Note that, similarly to the operation to the pick-up position, in the configuration in which the rotation unit 13 is rotated in the direction in which the gate bar holding unit 43 approaches the roadway 2, the rotation range of the rotation unit 13 is suppressed to 180 degrees as a whole. As compared with the configuration in which the rotation unit 13 is rotated 360 degrees, it is possible to easily accommodate the wiring and the like (not shown). On the other hand, in the configuration in which the gate bar holding unit 43 rotates the rotating unit 13 in the direction opposite to the direction approaching the roadway 2, there is nothing that projects to the lane side during the traveling direction change mode operation. Even when the vehicle is stopped on the lane, there is an advantage that the switching operation is possible. Therefore, the rotation direction of the rotation unit 13 by the rotation drive unit 22 in the traveling direction change mode may be selectable. For example, the rotation direction can be selected by the operation of the management PC 81 by an attendant. Also good.

  In addition, the gate device 1 that realizes the traveling direction switching mode of the present invention may be configured to be shared by the gate devices 1L and 1R disposed on the left and right islands 3L and 3R, and requires the traveling direction switching mode. Other gate devices that are not used may be configured in common without changing the structure. Thereby, the merit of scale can be increased and the device cost can be reduced. In order to share the gate device 1 in various ways as described above, the rotating housing 31 and the main body housing 21 are perpendicular to the horizontal rotating shaft 14 when viewed from above in a normal gate opening / closing state. A substantially bilaterally symmetric outer shape about a line passing through the rotation shaft 12 is desirable. Furthermore, it is desirable that the gate bar 16 has a vertically symmetrical outer shape with respect to the center passing through the horizontal rotation shaft 14 in the longitudinal direction of the gate bar 16 when viewed from the front in a recumbent position. These outer shapes need only be generally symmetric, and an opening / closing door or the like provided for maintenance may be provided at any position.

  In the present embodiment, the configuration in which the first stopper 23 and the second stopper 24 are erected on the island has been described, but the present invention is not limited to this configuration. For example, instead of the first stopper 23 and the second stopper 24, a stopper portion corresponding to the first and second stoppers 23, 24 extended from the main body housing 21 with an arm or the like is previously attached to the main body housing 21. The structure provided integrally may be sufficient. Furthermore, only the stopper portion corresponding to the first stopper 23 may be attached to the main body housing 21 and the second stopper 24 may be erected on the island.

  Further, the present invention can be appropriately changed without departing from the gist or concept of the invention that can be read from the claims and the entire specification, and a gate device and a gate control system with such a change are also included in the present invention. It is included in the technical idea.

  INDUSTRIAL APPLICABILITY The present invention can be suitably used for a gate device and a gate control system installed at a toll gate on a highway or a toll road.
