Description

本発明は、車両有料施設の料金所等に設置され、車両の通行を許可又は阻止する発進制御機に関する。 The present invention relates to a start controller that is installed at a toll booth or the like of a vehicle toll facility and that permits or blocks vehicle traffic.

高速道路等の有料道路における入口料金所、出口料金所等では、走行中の車両と自動的に無線通信を確立し、電子決済により課金処理を行う電子式料金収受システム（ＥＴＣ（登録商標）：Electronic Toll Collection System、「自動料金収受システム」とも言う）が利用されている。
このＥＴＣにおいては、料金所ゲートへの車両の進入を車両検知器が検知すると、車線サーバが路側アンテナに対して通信指令を発し、これに基づいて路側アンテナが車両に搭載された車載器との通信を開始する。次いで、車線サーバは路側アンテナにより車載器から得られた情報に基づいて、正常車両か異常車両かの別を判断する。そして、正常車両と判断した際には車両通行遮断機の阻止棒を開状態とし、異常車両と判断した際には阻止棒を閉状態に維持することで、車両の通行を許可するか、又は阻止するようになっている。 An electronic toll collection system (ETC (registered trademark)) that automatically establishes wireless communication with a running vehicle at a toll road such as a toll road such as an expressway and performs billing processing by electronic payment Electronic Toll Collection System, also called “automatic toll collection system”).
In this ETC, when the vehicle detector detects the entry of the vehicle to the toll gate, the lane server issues a communication command to the roadside antenna, and based on this, the roadside antenna is mounted on the vehicle mounted on the vehicle. Start communication. Next, the lane server determines whether the vehicle is a normal vehicle or an abnormal vehicle based on information obtained from the vehicle-mounted device by the roadside antenna. When the vehicle is determined to be a normal vehicle, the blocking rod of the vehicle passage breaker is opened, and when the vehicle is determined to be abnormal, the blocking rod is maintained in a closed state, thereby permitting the vehicle to pass, or It comes to stop.

ところで、ＥＴＣでは、例えばＥＴＣカードの未挿入等の要因によって、料金所ゲートへ進入した車両が異常車両であると判断された場合に、阻止棒への開指令が入力されないため阻止棒が開状態とならない。阻止棒が開状態にならずに車両が阻止棒に接触、衝突した場合に、車両や発進制御機が損傷することを防止するため、例えば特許文献１に開示されているように阻止棒（開閉バー）が水平方向に回動することで、阻止棒が車両から離れるように退避するリリース機構が発進制御機に採用されている。阻止棒が開状態にならずに、阻止棒の手前で車両が停止した場合は、収受員等の作業者が開指令を手動入力し、発進制御機を開状態にすることで車両の退出を行う。 By the way, in ETC, when it is determined that the vehicle that has entered the toll gate is an abnormal vehicle due to factors such as no insertion of an ETC card, the blocking bar is not opened because the opening command to the blocking bar is not input. Not. In order to prevent the vehicle and the start controller from being damaged when the vehicle comes into contact with or collides with the blocking bar without the blocking bar being opened, the blocking bar (open / closed as disclosed in Patent Document 1, for example) A release mechanism that retracts the blocking bar away from the vehicle by rotating the bar in the horizontal direction is employed in the starter controller. If the vehicle stops before the blocking rod without opening the blocking rod, the operator, such as a receipt person, manually inputs the opening command and opens the start controller to open the vehicle. Do.

ここで、阻止棒が開状態にならずに、阻止棒の直前で車両が停止した場合には、特に大型車両では車両の一部が阻止棒の上下動を阻害してしまい開状態として車両を退出させることが困難になる場合があり、阻止棒を車両から離れるように退避させて車両を通過させる必要がある。しかしながら、特許文献１に開示されたようなリリース機構では、収受員等の作業者が阻止棒の位置まで移動して手動でリリース操作を行い、車両を通過させる必要があった。このため、車両がリリースされるまでに時間を要してしまう。また、作業者の安全をより確実なものとするためには、作業者が車道に出て阻止棒を車両から離れるように退避させる作業を行うことを回避することが望まれていた。 Here, when the vehicle stops just before the blocking rod without opening the blocking rod, a part of the vehicle obstructs the vertical movement of the blocking rod, particularly in a large vehicle, and the vehicle is set in the open state. In some cases, it may be difficult to exit, and it is necessary to retract the blocking bar away from the vehicle and pass the vehicle. However, in the release mechanism disclosed in Patent Document 1, it is necessary for an operator such as a receiver to move to the position of the blocking bar and manually perform a release operation to pass the vehicle. For this reason, it takes time until the vehicle is released. Further, in order to ensure the safety of the worker, it has been desired to avoid the worker from going out to the roadway and retracting the blocking bar away from the vehicle.

本発明は、上記課題を解決するためになされたものであって、安全に、車両のリリースを行うことができる発進制御機を提供する。 The present invention has been made to solve the above-described problems, and provides a start control machine that can safely release a vehicle.

上記課題を解決するために、本発明は以下の手段を採用する。
本発明の第一の態様に係る発進制御機（１）は、阻止棒（２）と、前記阻止棒（２）を保持可能な保持部（３）と、前記保持部（３）に前記阻止棒（２）が保持された状態で、前記阻止棒（２）が車道（Ｒ）を閉じる閉位置（Ｐ１）から前記車道（Ｒ）を開放する開位置（Ｐ２）まで動作するように、前記保持部（３）を回転可能に支持する開閉機構（４）と、前記保持部（３）が前記閉位置（Ｐ１）にある状態で、前記阻止棒（２）が前記保持部（３）に保持されて前記車道（Ｒ）を閉じる使用位置（Ｐ１ａ）から、車両の進行方向（Ｄ）奥側（Ｄ２）に向けて延びるように配されるリリース位置（Ｐ１ｂ）まで、前記保持部（３）に対して前記阻止棒（２）をリリース軸（３３）回りに回転可能に支持するリリース回転機構（５）と、前記阻止棒（２）を、前記使用位置（Ｐ１ａ）から前記リリース位置（Ｐ１ｂ）へとリリース軸（３３）回りに回転させるように前記阻止棒（２）を押すリリース動作機構（６）と、前記リリース動作機構（６）の動作を制御する制御部（６１）と、を備えている。 In order to solve the above problems, the present invention employs the following means.
The start controller (1) according to the first aspect of the present invention includes a blocking rod (2), a holding portion (3) capable of holding the blocking rod (2), and the blocking portion (3). In a state where the rod (2) is held, the blocking rod (2) is operated from the closed position (P1) for closing the roadway (R) to the open position (P2) for opening the roadway (R). An opening / closing mechanism (4) that rotatably supports the holding portion (3), and the blocking rod (2) is attached to the holding portion (3) in a state where the holding portion (3) is in the closed position (P1). From the use position (P1a) held and closing the roadway (R) to the release position (P1b) arranged to extend toward the vehicle travel direction (D) back side (D2), the holding portion (3 A release rotating mechanism (5) that supports the blocking rod (2) so as to be rotatable about a release shaft (33) with respect to A release operation mechanism (6) for pushing the blocking bar (2) to rotate the blocking bar (2) around the release shaft (33) from the use position (P1a) to the release position (P1b); And a control unit (61) for controlling the operation of the release operation mechanism (6).

このような発進制御機によれば、制御部によってリリース動作機構を動作させることで、阻止棒を車両の進行方向奥側に車両から逃げるようにしてリリース位置まで自動で回転させることができる。従って、阻止棒の閉位置で車両が停止して車両が阻止棒の開閉を妨げる状態となった場合でも、作業者が車道に出て手動で阻止棒から車両をリリースする必要がなくなる。 According to such a start controller, by operating the release operation mechanism by the control unit, the blocking rod can be automatically rotated to the release position so as to escape from the vehicle to the back in the traveling direction of the vehicle. Accordingly, even when the vehicle stops at the closed position of the blocking bar and the vehicle is in a state where the blocking of the blocking bar is prevented, the operator does not have to go out onto the roadway and manually release the vehicle from the blocking bar.

また、本発明の第二の態様に係る発進制御機（１）では、上記第一の態様における前記阻止棒（２）は、前記保持部（３）が前記閉位置（Ｐ１）にある状態で前記リリース軸（３３）から前記車道（Ｒ）へと延びる本体部（１１）と、前記保持部（３）が前記閉位置（Ｐ１）にある状態で前記リリース軸（３３）から前記車道（Ｒ）とは反対側に延びる基部（１２）とを有し、前記リリース動作機構（６）は、前記阻止棒（２）が前記使用位置（Ｐ１ａ）にあるときに前記基部（１２）に押し付けられるとともに、前記阻止棒（２）が前記使用位置（Ｐ１ａ）から前記リリース位置（Ｐ１ｂ）に向けて回転する際に前記基部（１２）が移動する方向に、進出可能に設けられた進退部材（５１）と、前記進退部材（５１）の位置を検出する検出センサ（５２）と、前記制御部（６１）によって制御され、前記進退部材（５１）を前記阻止棒（２）の前記基部（１２）が移動する方向に進出させるとともに、前記検出センサ（５２）の検出結果に基づいて退避させるように動作する駆動部（５３）と、を有していてもよい。 In the start controller (1) according to the second aspect of the present invention, the blocking bar (2) in the first aspect is in a state where the holding part (3) is in the closed position (P1). The main body (11) extending from the release shaft (33) to the roadway (R) and the holding portion (3) are in the closed position (P1) from the release shaft (33) to the roadway (R). ), And the release operation mechanism (6) is pressed against the base (12) when the blocking bar (2) is in the use position (P1a). At the same time, when the blocking bar (2) rotates from the use position (P1a) toward the release position (P1b), the advancing / retracting member (51) is provided so as to be able to advance in the direction in which the base (12) moves. ) And detection for detecting the position of the advance / retreat member (51) Controlled by the sensor (52) and the controller (61), the advance / retreat member (51) is advanced in the direction in which the base (12) of the blocking rod (2) moves, and the detection sensor (52) And a drive unit (53) that operates to retreat based on the detection result.

このように、進退部材が阻止棒の基部を押すことによって阻止棒をリリース位置に移動させることができるため、簡易な構造で、容易に車両を阻止棒から自動でリリースすることができる。 Thus, since the advance / retreat member can move the blocking bar to the release position by pushing the base of the blocking bar, the vehicle can be easily released from the blocking bar with a simple structure.

また、本発明の第三の態様に係る発進制御機（１）では、上記第二の態様における前記駆動部（５３）は、前記阻止棒（２）の前記基部（１２）が移動する方向に前記進退部材（５１）を押し付けるとともに、前記基部が移動する方向と反対方向に退避可能な直動軸（５７）と、前記直動軸（５７）を進退駆動させるモータ本体（５８）と、を備える直動型ステッピングモータであってもよい。 In the start controller (1) according to the third aspect of the present invention, the drive part (53) in the second aspect is in a direction in which the base part (12) of the blocking bar (2) moves. A linear motion shaft (57) that presses the advance / retreat member (51) and retracts in a direction opposite to the direction in which the base moves, and a motor body (58) that drives the linear motion shaft (57) to advance and retract. It may be a direct acting stepping motor provided.

このように駆動部が直動型ステッピングモータであることで、容易に進退部材を阻止棒の基部が移動する方向に進退させることができる。 Thus, since the drive unit is a direct-acting stepping motor, the advance / retreat member can be easily advanced / retreated in the direction in which the base of the blocking rod moves.

また、本発明の第四の態様に係る発進制御機（１）では、上記第二又は第三の態様における前記リリース動作機構（６）は、前記基部（１２）が移動する方向に、前記進退部材（５１）に対して弾性力を与える弾性部材（５４）をさらに有していてもよい。 Further, in the start controller (1) according to the fourth aspect of the present invention, the release operation mechanism (6) in the second or third aspect is adapted to move in the direction in which the base portion (12) moves. You may further have the elastic member (54) which gives an elastic force with respect to a member (51).

このように弾性部材を設けることで、仮に、阻止棒の閉位置で車両が阻止棒に接触して車両により阻止棒が進行方向の奥側に押され、それにより阻止棒が保持部から外れた場合には、弾性部材の弾性力によって進退部材が進出する。その結果、検出センサによって進退部材の進出を検知することができる。 By providing the elastic member in this way, it is assumed that the vehicle contacts the blocking rod at the closed position of the blocking rod, and the blocking rod is pushed to the back in the traveling direction by the vehicle, so that the blocking rod is detached from the holding portion. In such a case, the advance / retreat member advances by the elastic force of the elastic member. As a result, the advancement of the advance / retreat member can be detected by the detection sensor.

上記の発進制御機によれば、リリース動作機構を用いて、安全に、車両のリリースを行うことができる。 According to the above start controller, the vehicle can be released safely using the release operation mechanism.

本実施形態では、阻止棒２に対して進退移動する進退部材として棒状部材５１を用いた例を説明するが、棒状部材５１に代えて他の部材を用いてもよい。即ち、進退部材は棒状をなすものに限定されず、例えばブロック状をなす部材や、中空状のパイプ等であってもよい。 The rod-shaped member 51 penetrates the opening / closing shaft 21 and is provided coaxially with the opening / closing shaft 21, and is movable relative to the opening / closing shaft 21 in the direction of the rotation axis O 1. Further, the bar-shaped member 51 also penetrates the bottom plate 15 of the holding part 3, and the blocking bar 2 is in a state where the blocking bar 2 is in the use position P 1 a, i. The distal end portion of the rod-shaped member 51 comes into contact with the blocking rod 2 from the back side D2 in the traveling direction D.

That is, the advance / retreat member is not limited to a rod-like member, and may be, for example, a block-like member, a hollow pipe, or the like.

この棒状部材５１には、棒状部材５１の基端部寄りの位置で、開閉用シャフト２１との間にコイルバネ等の弾性部材５４が介在されている。この弾性部材５４は、棒状部材５１に対して阻止棒２の基部１２が移動する方向、即ち、進行方向Ｄの手前側Ｄ１に向かう弾性力を与えている。これにより、棒状部材５１に回転軸線Ｏ１方向の外力が作用しない状態では、棒状部材５１の先端部が保持部３の底面板１５から手前側Ｄ１に飛び出した状態となる。
より具体的には、棒状部材５１は、基端部で、先端部に比べて外径寸法が小さくなっていることで、棒状部材５１には、段差面５１ａが形成されている。段差面５１ａの法線方向は、回転軸線Ｏ１の方向に沿っている。また開閉用シャフト２１には、開閉用シャフト２１における棒状部材５１の基端部側の端面から、回転軸線Ｏ１の方向に窪む回転軸線Ｏ１を中心とした柱状の空間Ｓが形成されている。空間Ｓの開口Ｓａには、棒状部材５１を回転軸線Ｏ１の方向に貫通させるとともに開口Ｓａを塞ぐようにして回転軸線Ｏ１を中心とした環状をなす蓋部材５９が開閉用シャフト２１に固定されて設けられている。

The elastic member 54 gives an elastic force to the rod-shaped member 51 in the direction in which the base 12 of the blocking bar 2 moves, that is, the front side D1 in the traveling direction D. Thereby, in a state where the external force in the direction of the rotation axis O 1 does not act on the rod-shaped member 51, the distal end portion of the rod-shaped member 51 protrudes from the bottom plate 15 of the holding unit 3 to the near side D 1.
More specifically, the rod-shaped member 51 has a base end portion that has a smaller outer diameter than the distal end portion, so that a step surface 51 a is formed on the rod-shaped member 51. The normal direction of the step surface 51a is along the direction of the rotation axis O1. Further, the opening / closing shaft 21 is formed with a columnar space S around the rotation axis O1 that is recessed in the direction of the rotation axis O1 from the end surface of the rod-shaped member 51 in the opening / closing shaft 21.

Is provided. The elastic member 54 is provided in a compressed state contracted from a natural length in a state where the blocking bar 2 is at the use position P1a.

検出センサ５２は、筐体２２の内部に配置された距離センサである。この検出センサ５２は、棒状部材５１に取り付けられた検知用ドグ５５と、棒状部材５１の回転軸線Ｏ１の方向への進退に伴う検知用ドグ５５の移動を検知する検知部５６とを有している。 The detection sensor 52 is a distance sensor disposed inside the housing 22.

Yes.

検知用ドグ５５は、棒状部材５１の基端部に設けられた回転軸線Ｏ１を中心とした板状（具体的には円盤状）をなし、棒状部材５１とともに回転軸線Ｏ１の方向に進退移動する。 The detection dog 55 has a plate shape (specifically a disk shape) centered on the rotation axis O1 provided at the base end of the rod-shaped member 51, and moves forward and backward in the direction of the rotation axis O1 together with the rod-shaped member 51. .

検知部５６は、筐体２２の内部で検知用ドグ５５に対向するように筐体２２に固定されており、検知用ドグ５５が所定の距離だけ検知部５６から遠ざかった際に、検出信号を後述する制御部６１へ送り、検出信号は、この制御部６１から収受員等の作業者が待機する事務所に送信される。検知部５６として用いられる距離センサの具体例としては、磁気式近接センサ、誘導型近接センサ、静電容量型近接センサ等が挙げられる。 The detection unit 56 is fixed to the housing 22 so as to face the detection dog 55 inside the housing 22, and when the detection dog 55 moves away from the detection unit 56 by a predetermined distance, a detection signal is output. The detection signal is sent to the control unit 61, which will be described later, and the detection signal is transmitted from the control unit 61 to an office where an operator such as a receiving person stands by. Specific examples of the distance sensor used as the detection unit 56 include a magnetic proximity sensor, an inductive proximity sensor, and a capacitive proximity sensor.

駆動部５３は、棒状部材５１及び開閉用シャフト２１よりも進行方向Ｄの奥側Ｄ２で筐体２２内に設けられている。
この駆動部５３は、阻止棒２の基部１２が移動する方向、即ち、回転軸線Ｏ１の方向に棒状部材５１を押し付ける直動軸５７と、直動軸５７を進退駆動させるモータ本体５８とを備える直動型ステッピングモータである。 The drive unit 53 is provided in the housing 22 on the back side D 2 in the traveling direction D from the rod-shaped member 51 and the opening / closing shaft 21.
The drive unit 53 includes a linear motion shaft 57 that presses the rod-shaped member 51 in the direction in which the base 12 of the blocking rod 2 moves, that is, the direction of the rotation axis O1, and a motor main body 58 that drives the linear motion shaft 57 to advance and retract. This is a direct acting stepping motor.

ここで、本実施形態の発進制御機１は、リリース動作機構６の動作を制御する制御部６１をさらに備えている。この制御部６１は筐体２２内に設けられて、駆動部５３に接続されているとともに、事務所からの操作信号に基づいて駆動部５３を動作するようになっている。 Here, the start controller 1 of the present embodiment further includes a controller 61 that controls the operation of the release mechanism 6. The control unit 61 is provided in the housing 22 and connected to the drive unit 53, and operates the drive unit 53 based on an operation signal from the office.

そして駆動部５３では、事務所からの操作信号を制御部６１が受信した際に、制御部６１によって直動軸５７を動作させるようになっている。そして、直動軸５７が棒状部材５１の基端部を押すことで、棒状部材５１を回転軸線Ｏ１の方向に阻止棒２の基部１２に向かって進出させ、棒状部材５１によって基部１２を押し付ける。また、事務所からの操作信号を制御部６１が受信した際に、制御部６１がモータ本体５８を通じて直動軸５７を棒状部材５１の基端部から退避させる。 In the driving unit 53, when the control unit 61 receives an operation signal from the office, the control unit 61 operates the linear motion shaft 57. Then, the linear movement shaft 57 pushes the base end portion of the rod-shaped member 51, thereby causing the rod-shaped member 51 to advance toward the base portion 12 of the blocking rod 2 in the direction of the rotation axis O 1 and press the base portion 12 by the rod-shaped member 51. Further, when the control unit 61 receives an operation signal from the office, the control unit 61 retracts the linear movement shaft 57 from the base end portion of the rod-shaped member 51 through the motor main body 58.

（阻止棒のリリース動作）
ここで、使用位置Ｐ１ａとリリース位置Ｐ１ｂとの間での阻止棒２の回転動作について説明する。
まず、車両が進行方向Ｄに発進制御機１に進入し、例えばＥＴＣカードの未挿入等によって異常車両と判断される。この時点で阻止棒２は、例えば車両に引っ掛かって停止しているか、又は、阻止棒２の上下の開閉動作を阻害する位置に停止している。 (Blocking bar release action)
Here, the rotation operation of the blocking bar 2 between the use position P1a and the release position P1b will be described.
First, the vehicle enters the start controller 1 in the traveling direction D, and is determined to be an abnormal vehicle by, for example, not inserting an ETC card. At this time, the blocking bar 2 is stopped by being caught by, for example, a vehicle, or stopped at a position where the vertical opening / closing operation of the blocking bar 2 is hindered.

次に、作業者が、事務所から制御部６１に対して操作信号を送信することで、駆動部５３の直動軸５７を棒状部材５１に向かって進出させる。そして、直動軸５７が棒状部材５１を基部１２に押し付けることで、保持部３の突起部材１９と阻止棒２の凹部１２ａとの固定が解除される。これにより、リリース軸３３の回転軸線Ｏ３を中心として、保持部３に対して阻止棒２を、使用位置Ｐ１ａからリリース位置Ｐ１ｂへと９０度回転させる。リリース位置Ｐ１ｂでは、ロックレバー部３５のフック部４６が固定部材４２に固定され、ロックレバー部３５が保持部３に固定される。 Next, the operator advances the linear motion shaft 57 of the drive unit 53 toward the rod-shaped member 51 by transmitting an operation signal from the office to the control unit 61. Then, the linear motion shaft 57 presses the rod-shaped member 51 against the base portion 12, whereby the fixing of the protruding member 19 of the holding portion 3 and the concave portion 12 a of the blocking rod 2 is released. As a result, the blocking rod 2 is rotated 90 degrees from the use position P1a to the release position P1b with respect to the holding portion 3 around the rotation axis O3 of the release shaft 33. At the release position P1b, the hook portion 46 of the lock lever portion 35 is fixed to the fixing member 42, and the lock lever portion 35 is fixed to the holding portion 3.

棒状部材５１には、弾性部材５４によって弾性力が与えられているため、駆動部５３の直動軸５７を棒状部材５１に向かって進出させて直動軸５７が棒状部材５１を押した際、棒状部材５１が進行方向Ｄの手前側Ｄ１に向かって開閉用シャフト２１及び保持部３に対して自動的に相対移動する。 Since elastic force is given to the rod-shaped member 51 by the elastic member 54, when the linear motion shaft 57 of the drive unit 53 is advanced toward the rod-shaped member 51 and the linear motion shaft 57 presses the rod-shaped member 51, The rod-shaped member 51 is automatically moved relative to the opening / closing shaft 21 and the holding portion 3 toward the front side D1 in the traveling direction D.

ここで、阻止棒２がリリース位置Ｐ１ｂに向かって回転する際、保持部３には、基端部に設けられたウェイト２０の重力によって、基端部が下方に向かうようにモーメントが作用し、保持部３は、回転軸線Ｏ２を中心として回転する。この際、阻止棒２には保持部３とは反対方向へのモーメント、即ち、基部１２が上方へ向かうように阻止棒２にモーメントが作用する。保持部３は開閉用シャフト２１に対して傾斜して設けられていることで、（例えば車両が阻止棒２を押すことによって）このような上方へ向かうモーメントが阻止棒２に作用すると、保持部３に対して阻止棒２が遠ざかる方向に力が作用し、自動的に使用位置Ｐ１ａからリリース位置Ｐ１ｂまで、阻止棒２が回転する。 Here, when the blocking bar 2 rotates toward the release position P1b, a moment acts on the holding portion 3 so that the base end portion is directed downward due to the gravity of the weight 20 provided at the base end portion. The holding unit 3 rotates around the rotation axis O2. At this time, a moment acts on the blocking rod 2 in a direction opposite to the holding portion 3, that is, a moment acts on the blocking rod 2 so that the base portion 12 is directed upward. Since the holding portion 3 is provided to be inclined with respect to the opening / closing shaft 21, when the upward moment acts on the blocking rod 2 (for example, when the vehicle pushes the blocking rod 2), the holding portion 3 A force is applied in a direction in which the blocking bar 2 moves away from 3 and the blocking bar 2 automatically rotates from the use position P1a to the release position P1b.

そして阻止棒２がリリース位置Ｐ１ｂに到達した時点で、進行方向Ｄの奥側Ｄ２に向かって車両を進行させて発進制御機１を通過させる。 When the blocking bar 2 reaches the release position P1b, the vehicle is advanced toward the back side D2 in the traveling direction D and the start controller 1 is passed.

阻止棒２がリリース位置Ｐ１ｂに到達した時点では棒状部材５１が進出していることで、使用位置Ｐ１ａに阻止棒２が有る状態と比べて検知用ドグ５５の位置が所定の距離だけ検知部５６から遠ざかっている。よって検出信号が事務所へ送信される（リリース検知）。この検出信号を確認して、即ち検出結果に基づいて、事務所からの作業者による操作により、操作信号を制御部６１に送信することで、駆動部５３の直動軸５７が、棒状部材５１から離れるように退避する。 When the blocking bar 2 reaches the release position P1b, the bar-shaped member 51 has advanced, so that the position of the detection dog 55 is a predetermined distance compared to the state where the blocking bar 2 is in the use position P1a. Away from. Therefore, a detection signal is transmitted to the office (release detection). By confirming this detection signal, that is, based on the detection result, an operation signal is transmitted to the control unit 61 by an operation by an operator from the office, so that the linear movement shaft 57 of the drive unit 53 can be Evacuate away from.

その後、ロックレバー部３５を作業者が操作することにより、阻止棒２が使用位置Ｐ１ａに復帰して保持部３の突起部材１９を阻止棒２の凹部１２ａに入り込ませるとともに、阻止棒２の基部１２によって棒状部材５１を進行方向Ｄの奥側Ｄ２に向かって押して、発進制御機１を通常の運用に戻す。なお、上述したように、自動リリース復帰機構を用いて阻止棒２を使用位置Ｐ１ａに復帰させてもよい。
ここで、作業者の操作によって駆動部５３の直動軸５７の退避を行う場合に限らず、検知基準（検知用ドグ５５）が検知部５６から所定距離だけ離れていたら、自動的に直動軸５７の退避を行ってもよい。
また、検知基準（検知用ドグ５５）が検知部５６から所定距離だけ離れている時間を制御部６１で監視し、所定の時間経過した時点で、自動的に直動軸５７の退避を行ってもよい。
さらに、棒状部材５１の先端部が基部１２に非接触となっている状態を検知するセンサを別途設け、棒状部材５１と基部１２との非接触を検知した時点で、自動的に直動軸５７の退避を行ってもよい。 Thereafter, when the operator operates the lock lever portion 35, the blocking rod 2 returns to the use position P1a, and the protruding member 19 of the holding portion 3 enters the recess 12a of the blocking rod 2, and the base portion of the blocking rod 2 12, the rod-shaped member 51 is pushed toward the back side D2 in the traveling direction D, and the start controller 1 is returned to the normal operation. As described above, the blocking rod 2 may be returned to the use position P1a using an automatic release return mechanism.
Here, not only when the linear motion shaft 57 of the drive unit 53 is retracted by the operator's operation, but when the detection reference (detection dog 55) is separated from the detection unit 56 by a predetermined distance, the linear motion is automatically performed. The shaft 57 may be retracted.
Further, the control unit 61 monitors the time that the detection reference (detection dog 55) is separated from the detection unit 56 by a predetermined distance, and automatically retracts the linear motion shaft 57 when the predetermined time has elapsed. Also good.
Further, a separate sensor for detecting a state where the tip of the rod-shaped member 51 is not in contact with the base 12 is provided, and when the non-contact between the rod-shaped member 51 and the base 12 is detected, the linear motion shaft 57 is automatically detected. May be evacuated.

（発進制御機の作用、効果）
以上説明した本実施形態の発進制御機１によると、制御部６１によってリリース動作機構６を動作させることで、阻止棒２を車両の進行方向Ｄの奥側Ｄ２に、車両から逃げるようにしてリリース位置Ｐ１ｂまで自動で回転させることができる。 (Operation and effect of start controller)
According to the above-described start controller 1 of the present embodiment, the control unit 61 operates the release operation mechanism 6 to release the blocking bar 2 so as to escape from the vehicle to the inner side D2 in the traveling direction D of the vehicle. It can be automatically rotated to the position P1b.

従って、阻止棒２の閉位置Ｐ１で車両が停止して、車両が阻止棒２の開閉動作を妨げる状態となった場合であっても、作業者が車道Ｒに出て手動で阻止棒２から車両をリリースする必要がなくなる。この結果、安全かつ容易に、車両のリリースを行うことができる。
また、阻止棒２の閉位置で車両が阻止棒２に接触して、阻止棒２が進行方向の奥側に押され、それにより阻止棒２が保持部３から外れた場合には、弾性部材５４の弾性力によって棒状部材５１が進出する。その結果、検出センサ５２によって棒状部材５１の進出を検知することができる。 Therefore, even when the vehicle stops at the closed position P1 of the blocking bar 2 and the vehicle is in a state of hindering the opening / closing operation of the blocking bar 2, the operator goes out to the roadway R and manually moves from the blocking bar 2 There is no need to release the vehicle. As a result, the vehicle can be released safely and easily.
In addition, when the vehicle comes into contact with the blocking rod 2 at the closed position of the blocking rod 2 and the blocking rod 2 is pushed to the far side in the traveling direction, and thereby the blocking rod 2 is detached from the holding portion 3, the elastic member The rod-shaped member 51 advances by the elastic force 54. As a result, the advancement of the rod-shaped member 51 can be detected by the detection sensor 52.

さらに本実施形態では、棒状部材５１が阻止棒２の基部１２を押すことによって阻止棒２を使用位置Ｐ１ａからリリース位置Ｐ１ｂに移動させるようになっている。このため、さらに簡易な構造で車両を阻止棒２から自動でリリースすることができる。 Furthermore, in this embodiment, the bar-shaped member 51 moves the blocking bar 2 from the use position P1a to the release position P1b by pushing the base 12 of the blocking bar 2. For this reason, the vehicle can be automatically released from the blocking bar 2 with a simpler structure.

また、検出センサ５２を用いて棒状部材５１の位置を検出することで、棒状部材５１が進行方向Ｄの奥側Ｄ２に向かって、保持部３に対して退避可能となるように駆動部５３の直動軸５７が動作する。この際、棒状部材５１に設けられた弾性部材５４の弾性力によって、阻止棒２を保持部３による保持力から解放し、使用位置Ｐ１ａから動かすために必要となる押し出し力（駆動部５３の直動軸５７からシャフト５１へ加えられる力）を抑えつつ、棒状部材５１を阻止棒２の基部１２に押し付けて、容易に阻止棒２をリリース位置Ｐ１ｂに移動させることができる（阻止棒２が使用位置Ｐ１ａから移動するには、弾性力と押し出し力とを合わせた力の大きさが、保持部３による保持力を上回ればよい）。従って、駆動部５３で必要な動力を抑えることができ、例えば、駆動部５３の小型化につながる。なお、この押し出し力の大きさは、弾性部材による力によらず、単独で阻止棒２を使用位置Ｐ１ａから動かせるだけの大きさであってもよい。
さらに、仮に、阻止棒２の閉位置Ｐ１で車両が阻止棒に接触し、車両が阻止棒２を進行方向Ｄの奥側Ｄ２に押した場合、（駆動軸５３の力によらず）弾性部材５４の弾性力によって、自動的に阻止棒２をリリース位置Ｐ１ｂに向けて動作させることができる。即ち、駆動部５３を用いることなく、阻止棒２を回転動作させることができ、車両のリリースが可能となる。 Further, by detecting the position of the bar-shaped member 51 using the detection sensor 52, the drive unit 53 can be retracted with respect to the holding unit 3 toward the inner side D 2 in the traveling direction D. The linear movement shaft 57 operates. At this time, by the elastic force of the elastic member 54 provided on the rod-like member 51, the blocking force 2 is released from the holding force by the holding portion 3 and is required to move from the use position P1a (direct force of the driving portion 53). While suppressing the force applied to the shaft 51 from the moving shaft 57, the bar-shaped member 51 can be pressed against the base 12 of the blocking bar 2 to easily move the blocking bar 2 to the release position P1b (the blocking bar 2 is used). In order to move from the position P1a, it is sufficient that the magnitude of the combined force of the elastic force and the pushing force exceeds the holding force by the holding unit 3). Therefore, the power required by the drive unit 53 can be suppressed, and for example, the drive unit 53 can be downsized. In addition, the magnitude | size of this pushing force may be a magnitude | size which can move the blocking bar 2 independently from use position P1a independently of the force by an elastic member.
Furthermore, if the vehicle contacts the blocking rod at the closed position P1 of the blocking rod 2 and the vehicle pushes the blocking rod 2 to the back side D2 in the traveling direction D (regardless of the force of the drive shaft 53), the elastic member By the elastic force of 54, the blocking bar 2 can be automatically operated toward the release position P1b. That is, the blocking rod 2 can be rotated without using the drive unit 53, and the vehicle can be released.

また、本実施形態では、駆動部５３が直動型ステッピングモータであるため、棒状部材５１の押し付けを非常に簡易な構成で行うことができるとともに、棒状部材５１の退避も容易であるため、阻止棒２の使用位置Ｐ１ａへの復帰も容易である。 Further, in the present embodiment, since the drive unit 53 is a direct-acting stepping motor, the bar-shaped member 51 can be pressed with a very simple configuration, and the bar-shaped member 51 can be easily retracted. It is easy to return the rod 2 to the use position P1a.

さらに、阻止棒２をリリース位置Ｐ１ｂへ回転させる際に、棒状部材５１が阻止棒２の基部１２を押す構成になっているため、車道Ｒから離れた位置にリリース動作機構６を設置することができる。このため、リリース動作機構６が車両の通行の妨げになることを回避することができる。また、このように棒状部材５１が阻止棒２の基部１２を押すことで、棒状部材５１が阻止棒２の本体部１１を押す場合に比べて、阻止棒２に対してより大きな回転モーメントを付与することができ、容易に阻止棒２を使用位置Ｐ１ａからリリース位置Ｐ１ｂへ回転させることができる。 Furthermore, when the blocking bar 2 is rotated to the release position P1b, the bar-shaped member 51 is configured to push the base 12 of the blocking bar 2, so that the release operation mechanism 6 can be installed at a position away from the roadway R. it can. For this reason, it can be avoided that the release operation mechanism 6 hinders the passage of the vehicle. Further, when the rod-shaped member 51 pushes the base portion 12 of the blocking rod 2 in this way, a larger rotational moment is applied to the blocking rod 2 than when the rod-shaped member 51 pushes the main body portion 11 of the blocking rod 2. The blocking rod 2 can be easily rotated from the use position P1a to the release position P1b.

以上、本発明の実施形態について詳細を説明したが、本発明の技術的思想を逸脱しない範囲内において、多少の設計変更も可能である。
例えば、本実施形態では、棒状部材５１が開閉用シャフト２１を貫通するように設けられているが、この棒状部材５１は開閉用シャフト２１とは異なる位置、例えば開閉用シャフト２１と同じ高さで、開閉用シャフト２１を貫通しない位置に設けられていてもよい。 Although the embodiment of the present invention has been described in detail above, some design changes can be made without departing from the technical idea of the present invention.
For example, in this embodiment, the rod-shaped member 51 is provided so as to penetrate the opening / closing shaft 21, but the rod-shaped member 51 is at a position different from the opening / closing shaft 21, for example, at the same height as the opening / closing shaft 21. Further, it may be provided at a position not penetrating the opening / closing shaft 21.

さらに、駆動部５３は直動型ステッピングモータである場合に限られず、例えば回転型のモータに歯車等の伝達機構を設けて、棒状部材５１を進退させるようにしてもよい。 Furthermore, the drive unit 53 is not limited to a direct-acting stepping motor. For example, a transmission mechanism such as a gear may be provided in a rotary motor to advance and retract the rod-shaped member 51.

さらに棒状部材５１には、必ずしも弾性部材５４を設けなくともよい。
なお、特開２０１２−２１４９９１号公報には、遮断棹を退避位置へ移動させる発明が記載されているが、本発明とはその構造が異なる。 Furthermore, the rod-shaped member 51 is not necessarily provided with the elastic member 54.
Japanese Patent Application Laid-Open No. 2012-214991 describes an invention for moving a blocking rod to a retracted position, but its structure is different from that of the present invention.
