Abstract

PROBLEM TO BE SOLVED: To provide a start controller with an automatic return mechanism that does not require plural driving sources and enables return operation of an opening/closing bar in a release state to be performed automatically.SOLUTION: The top of a body 6 is provided with a guide member 42 that keeps in contact with an opening/closing bar 12 or a bar holder 14 during return operation to guide the opening/closing bar 12 so that it gradually goes back from a release position to a normal position.

Description

本発明は、有料道路の出入口付近に設置されるＥＴＣ（登録商標）等の交通管制機器において、リリース状態からの復帰を自動で行う自動復帰機構を備えた発進制御機に関する。   The present invention relates to a start controller provided with an automatic return mechanism for automatically returning from a released state in a traffic control device such as ETC (registered trademark) installed near an entrance / exit of a toll road.

高速道路等の有料道路の出入口におけるＥＴＣ（登録商標）レーンには、棒状の開閉バーの開閉動作によって車両通行の許可・不許可を運転者に知らせる発進制御機が設置されている。多くの発進制御機では、閉位置（車両通行が不許可の状態）にある開閉バーに車両が接触・衝突した場合に、該車両や発進制御機の深刻な損傷を防止すべく、該開閉バーが略水平方向に回動していわゆるリリース位置（退避位置）に移動できるようになっている。   An ETC (registered trademark) lane at the entrance and exit of a toll road such as an expressway is provided with a start controller that informs the driver of permission or disapproval of vehicle traffic by opening and closing a bar-shaped opening and closing bar. In many start controllers, when a vehicle contacts or collides with an open / close bar in a closed position (vehicle passage is not permitted), the open / close bar is used to prevent serious damage to the vehicle or the start controller. Can be moved to a so-called release position (retracted position) by rotating in a substantially horizontal direction.

例えば特許文献１には、阻止棒３４を支持部材３０に回動可能に取り付けるヒンジピン３６を、車両の通過方向又は車両の走行路と反対側へ傾斜させ、退避位置へ回動した阻止棒の戻り回動を、重力によるモーメントを利用して防止することを企図した車両用ゲート開閉装置が開示されている。   For example, in Patent Document 1, the hinge pin 36 that rotatably attaches the blocking bar 34 to the support member 30 is tilted in the vehicle passing direction or the opposite side of the vehicle traveling path, and the blocking bar returned to the retracted position is returned. A gate opening and closing device for a vehicle that is intended to prevent rotation by utilizing a moment due to gravity is disclosed.

また特許文献２には、遮断竿６が水平方向に回動して退避位置に移動したときに、スイッチ操作で遮断竿６を垂直方向回動状態に戻すことができる遮断竿復帰装置を備えた通行遮断機が開示されている。   Further, Patent Document 2 includes a shut-off rod returning device that can return the shut-off rod 6 to a vertical-rotation state by a switch operation when the shut-off rod 6 rotates in the horizontal direction and moves to the retracted position. A traffic barrier is disclosed.

一方特許文献３には、車両の通行を規制する開閉バー１２が、車両通過方向の前方斜め上方に回動して跳ね上がるように構成された車両通行制御装置が開示されている。   On the other hand, Patent Document 3 discloses a vehicle traffic control device in which an open / close bar 12 that regulates vehicle traffic is configured to rotate and jump up diagonally forward in the vehicle passing direction.

特開２００５−６８８８６号公報JP 2005-68886 A 特開２０１１−５８３３１号公報JP 2011-58331 A 特表２０１０−１９６３６７号公報Special table 2010-196367

特許文献１及び２に記載のような装置の通常の動作では、阻止棒（遮断竿）は、閉位置では概ね水平状態に片持ちされ、開位置ではその一端が跳ね上がるように動作して概ね垂直状態になる。一方、閉位置にある阻止棒（遮断竿）に車両が衝突した場合、その衝撃を緩和するために、該阻止棒（遮断竿）は概ね水平方向に回動して退避位置に移動する。しかし特許文献１に記載のゲート開閉装置では、退避位置に移動した阻止棒を元の状態に復帰させる操作は手動で行う必要があると解され、作業者の負担が大きい上に復帰に時間がかる。   In the normal operation of the devices as described in Patent Documents 1 and 2, the blocking bar (blocking rod) is cantilevered in a substantially horizontal state in the closed position, and is moved so that one end of the blocking bar jumps up in the open position. It becomes a state. On the other hand, when the vehicle collides with the blocking bar (blocking rod) in the closed position, the blocking rod (blocking rod) rotates in the horizontal direction and moves to the retracted position in order to reduce the impact. However, in the gate opening / closing device described in Patent Document 1, it is understood that the operation of returning the blocking rod moved to the retracted position to the original state needs to be performed manually, which is heavy on the operator and takes time to return. .

また特許文献２に記載の発明では、退避位置に移動した遮断竿を自動で復帰させることができるが、通常の（垂直方向の）開閉動作を行うための駆動装置３に加え、退避位置にある遮断竿６を垂直方向回動状態に押し戻すための復帰装置５が設けられており、要するに実質２つの駆動源が必要となり、装置のコストアップ及び複雑化につながる。   In the invention described in Patent Document 2, the barrier rod that has moved to the retracted position can be automatically restored, but is in the retracted position in addition to the driving device 3 for performing a normal (vertical) opening / closing operation. A return device 5 is provided for pushing back the blocking rod 6 to the vertical rotation state. In short, substantially two drive sources are required, leading to an increase in cost and complexity of the device.

一方、特許文献３に記載の車両通行制御装置は、１つの開閉バー１２に対して１つのサーボモータ２０のみを使用しているが、開閉バー１２の通常の開閉動作と、車両が衝突したときの動作は同一である（いずれの場合も前方斜め上方に跳ね上がる）と解される。従って車両の衝突時に開閉バーが退避位置（リリース状態）に移動することはないので、そもそも復帰機構を設ける必要がないが、復帰動作中は開閉バーが車両通行空間と干渉することになる。さらに特許文献３の装置では、開閉バーの軌道が車両運転者の進行方向成分も含むため、開閉動作中の開閉バーの軌道範囲内には通行車両の存在が許容されないという課題がある。   On the other hand, the vehicle traffic control device described in Patent Document 3 uses only one servo motor 20 for one opening / closing bar 12, but when the vehicle collides with the normal opening / closing operation of the opening / closing bar 12. Is understood to be the same (in any case, it jumps forward and obliquely upward). Therefore, since the opening / closing bar does not move to the retracted position (released state) at the time of a vehicle collision, it is not necessary to provide a return mechanism in the first place, but the opening / closing bar interferes with the vehicle traffic space during the return operation. Furthermore, in the device of Patent Document 3, since the track of the opening / closing bar also includes a traveling direction component of the vehicle driver, there is a problem that the presence of a passing vehicle is not allowed within the track range of the opening / closing bar during the opening / closing operation.

そこで本発明は、複数の駆動源を必要とせず、リリース位置（退避位置）にある開閉バーの復帰動作を自動で行える自動復帰機構を備えた発進制御機を提供することを目的とする。   Therefore, an object of the present invention is to provide a start controller having an automatic return mechanism that does not require a plurality of drive sources and can automatically return the opening / closing bar at the release position (retracted position).

上記目的を達成するために、本願第１の発明は、本体と、該本体に対して駆動軸回りに回転可能に取り付けられたアームと、該アームに対して、前記駆動軸に垂直な回動軸回りに回動可能に取り付けられた開閉バーと、を有し、該開閉バーが、前記駆動軸の駆動によって、略水平に延びて車両の通行を阻止する閉位置と、該閉位置から垂直方向に回転して車両の通行を許可する開位置との間を移動可能に構成されており、かつ、前記閉位置にあるときに前記アームに対して前記回動軸回りに略水平方向に回動してリリース位置に移動可能に構成されている、発進制御機において、鉛直方向よりも前記閉位置にある開閉バーと反対側に傾斜したガイド部分を有するガイド部材が設けられ、該ガイド部材は、前記開閉バーが前記リリース位置にある状態で前記アームが前記駆動軸回りに回転したときに、予め定めた前記アームの復帰動作回転角度範囲内において前記ガイド部分が常時前記開閉バーに当接して、該当接によって前記開閉バーが前記ガイド部材から受ける力によって、前記開閉バーが前記アームに対して前記回動軸回りに回動して前記リリース位置から復帰するように構成されている、発進制御機を提供する。   In order to achieve the above object, the first invention of the present application is directed to a main body, an arm attached to the main body so as to be rotatable about a drive shaft, and a rotation perpendicular to the drive shaft with respect to the arm. An open / close bar attached to be rotatable about an axis, the open / close bar extending substantially horizontally by driving the drive shaft to prevent passage of the vehicle, and a vertical position from the closed position. It is configured to be movable between an open position that rotates in a direction and permits passage of the vehicle, and rotates in a substantially horizontal direction around the rotation axis with respect to the arm when in the closed position. In the start controller configured to move and move to the release position, a guide member having a guide portion inclined to the opposite side of the open / close bar at the closed position from the vertical direction is provided, The open / close bar is at the release position. When the arm rotates about the drive shaft in a state, the guide portion always abuts on the opening / closing bar within a predetermined return rotation angle range of the arm, and the opening / closing bar is guided by the contact. There is provided a start controller configured such that the opening / closing bar rotates about the rotation axis with respect to the arm and returns from the release position by a force received from a member.

第２の発明は、第１の発明において、前記アームの復帰動作回転角度範囲は、前記開閉バーが前記閉位置にあるときの前記駆動軸の回転角度位置をゼロ度としたときに、７５°〜１２５°の回転角度範囲内に限定される、発進制御機を提供する。   According to a second aspect of the present invention, in the first aspect of the present invention, the return operation rotation angle range of the arm is 75 ° when the rotation angle position of the drive shaft when the open / close bar is in the closed position is zero degrees. A start controller is provided that is limited to within a rotational angle range of ~ 125 °.

第３の発明は、第１又は第２の発明において、前記開閉バーを前記リリース位置に保持するロック機構が前記アーム内に設けられ、前記ロック機構に関連付けられるとともに、前記アームの前記本体に面する面から、該面に対して変位可能に突出する突出部材が設けられ、前記本体の前記アームに面する面には、前記アームが復帰動作回転角度範囲内にあるときに前記突出部材に当接して前記突出部材を変位させる凸部が設けられ、前記突出部材は、前記凸部に当接して変位している間は前記ロック機構を解除するように構成されている、発進制御機を提供する。   According to a third invention, in the first or second invention, a lock mechanism for holding the open / close bar in the release position is provided in the arm, and is associated with the lock mechanism, and faces the main body of the arm. A projecting member projecting from the surface to be displaceable relative to the surface, and the surface facing the arm of the main body contacts the projecting member when the arm is within a return operation rotation angle range. Provided is a start controller that is provided with a convex portion that contacts and displaces the protruding member, and the protruding member is configured to release the lock mechanism while being displaced in contact with the convex portion. To do.

第４の発明は、第１〜第３の発明のいずれか１つにおいて、前記ガイド部材に当接する前記開閉バーの部位に、自由回転可能なローラが設けられ、前記ガイド部材は、前記アームの復帰動作回転角度範囲内では常時前記ローラに当接するように構成される、発進制御機を提供する。   According to a fourth invention, in any one of the first to third inventions, a freely rotatable roller is provided at a portion of the opening / closing bar that contacts the guide member, and the guide member is provided on the arm. Provided is a start controller configured to always contact the roller within a return operation rotation angle range.

本発明によれば、リリース位置からの開閉バーの自動復帰動作を、アームの回転に伴う開閉バーとガイド部材との当接によって行うことができる。従って、自動復帰動作のための駆動源を別途必要とせず、コンパクトかつ低コストの発進制御機が提供される。   According to the present invention, the automatic return operation of the open / close bar from the release position can be performed by the contact between the open / close bar and the guide member accompanying the rotation of the arm. Accordingly, a compact and low-cost start controller is provided that does not require a separate drive source for the automatic return operation.

アームの復帰動作回転角度範囲を７５°〜１２５°の回転角度範囲内とすることにより、開閉バーの復帰動作を車両通行空間外で行うことができ、復帰動作時に開閉バーが車両通行空間内に進入することを防止できる。   By setting the arm return operation rotation angle range within the rotation angle range of 75 ° to 125 °, the return operation of the open / close bar can be performed outside the vehicle traffic space. It is possible to prevent entry.

開閉バーをリリース位置に保持するロック機構に関連付けた突出部材と、本体側に設けた凸部との組み合わせにより、アームの回転動作中に自動的にロック機構を解除することができる。   The combination of the protruding member associated with the lock mechanism that holds the open / close bar in the release position and the convex portion provided on the main body side enables the lock mechanism to be automatically released during the rotation of the arm.

開閉バーに自由回転可能なローラを設け、該ローラに常に当接するようにガイド部材を構成することにより、開閉バーとガイド部材との摩擦を転がり摩擦にして円滑な動作を実現することができる。   By providing a freely rotatable roller on the opening / closing bar and configuring the guide member so as to always contact the roller, a smooth operation can be realized by rolling the friction between the opening / closing bar and the guide member.

図１は、本発明の好適な実施形態に係る発進制御機２を示す外観斜視図である。発進制御機２は、地面等の設置面４に固定配置された略直方体形状の本体６と、本体６の車両進入側の側面に、設置面４に略平行（一般に略水平）な回転軸８について回転可能に取り付けられたアーム１０と、アーム１０に対して所定の角度範囲内で回動可能に設けられた開閉バー１２とを有する。図示例では、開閉バー１２はその一端がバーホルダ１４に固定されていわゆる片持ち式に支持されており、バーホルダ１４がアーム１０に対して、アーム１０の回転軸８に垂直な回動軸１６について、少なくとも９０°の回動角度範囲内で回動可能に取り付けられている。なお本実施形態では、矢印１８で示す方向に車両が通行するものとし、アーム１０の回転軸８は車両通行方向１８に概ね平行であるとする。   FIG. 1 is an external perspective view showing a start controller 2 according to a preferred embodiment of the present invention. The start controller 2 includes a substantially rectangular parallelepiped main body 6 fixedly disposed on an installation surface 4 such as the ground, and a rotating shaft 8 that is substantially parallel to the installation surface 4 (generally substantially horizontal) on the side surface of the main body 6 on the vehicle entry side. The arm 10 is rotatably attached to the arm 10 and the opening / closing bar 12 is provided so as to be rotatable with respect to the arm 10 within a predetermined angle range. In the illustrated example, one end of the open / close bar 12 is fixed to the bar holder 14 and is supported in a so-called cantilever manner. The bar holder 14 is relative to the arm 10 with respect to the rotation shaft 16 perpendicular to the rotation shaft 8 of the arm 10. , And is attached so as to be rotatable within a rotation angle range of at least 90 °. In the present embodiment, it is assumed that the vehicle passes in the direction indicated by the arrow 18, and the rotating shaft 8 of the arm 10 is substantially parallel to the vehicle passing direction 18.

アーム１０は、図示しない駆動源によって本体６に対して回転駆動される。アーム１０の駆動源としては例えば種々の電動機（図示せず）等が使用可能であるが、アーム１０の回転角度位置を正確に制御できるサーボモータが好ましい。   The arm 10 is rotationally driven with respect to the main body 6 by a driving source (not shown). As a drive source of the arm 10, for example, various electric motors (not shown) can be used, but a servo motor capable of accurately controlling the rotation angle position of the arm 10 is preferable.

通常の開閉動作では、開閉バー１２は、図１（ａ）に示すように略水平に延びて車両の通行を阻止する閉位置と、図１（ｂ）に示すように略垂直に延びて車両の通行を許可する開位置との間を、アーム１０の回転動作によって垂直方向に移動する。より詳細には、図１（ａ）の閉位置での本体６に対するアーム１０の回転角度位置をゼロ度とすると、図１（ｂ）に示す開位置ではアーム１０は、開閉バー１２が車両通行の妨げとならない位置に移動するまで回転する。通常、開位置でのアームの回転角度位置は９０度に近い角度であり、図示例では８５．５度である。この通常の開閉動作では、アーム１０に対するバーホルダ１４（開閉バー１２）の回動角度位置は変化しない。   In a normal opening / closing operation, the opening / closing bar 12 extends substantially horizontally as shown in FIG. 1A to prevent the vehicle from passing therethrough, and extends substantially vertically as shown in FIG. 1B. The arm 10 is moved in the vertical direction between the open positions where the passage of the arm 10 is permitted. More specifically, assuming that the rotation angle position of the arm 10 with respect to the main body 6 in the closed position in FIG. 1A is zero degree, the arm 10 in the open position shown in FIG. Rotate until it moves to a position that does not interfere with the movement. Usually, the rotation angle position of the arm in the open position is an angle close to 90 degrees, and is 85.5 degrees in the illustrated example. In this normal opening / closing operation, the rotational angle position of the bar holder 14 (opening / closing bar 12) with respect to the arm 10 does not change.

ここで本来であれば、矢印１８の方向に進行する車両（図示せず）は、開閉バー１２が閉位置（図１（ａ））にあるときは発進制御機２の側方を通過してはならないのであるが、速度超過や運転者の不注意等の原因により開閉バー１２に接触してしまうことがある。このような場合、車両又は発進制御機の深刻な損傷を防止するために、図１（ｃ）に示すように、開閉バー１２がアーム１０に対して略水平方向に約９０度回動して、いわゆるリリース位置（退避位置）に移動する。つまりバーホルダ１４は、開閉バー１２に所定値以上の力が略水平方向に作用したときは、アーム１０に対して略９０度水平方向に回動して開閉バー１２を車両から退避させるとともに、該リリース位置から開閉バー１２が走行路側に回転して（跳ね戻って）車両と再接触しないように、後述するロック機構によって上記リリース位置に保持される。   Originally, the vehicle (not shown) traveling in the direction of the arrow 18 passes through the side of the start controller 2 when the open / close bar 12 is in the closed position (FIG. 1A). Although it must not be done, it may come into contact with the open / close bar 12 due to an excessive speed or carelessness of the driver. In such a case, in order to prevent serious damage to the vehicle or the start controller, as shown in FIG. 1 (c), the open / close bar 12 rotates about 90 degrees in the substantially horizontal direction with respect to the arm 10. Then, it moves to a so-called release position (retracted position). In other words, the bar holder 14 rotates about 90 degrees horizontally with respect to the arm 10 when a force of a predetermined value or more acts on the opening / closing bar 12 to retract the opening / closing bar 12 from the vehicle. The opening / closing bar 12 is held at the release position by a lock mechanism, which will be described later, so that the open / close bar 12 does not rotate (bounce back) from the release position and re-contact with the vehicle.

次に、図１（ｃ）に示すリリース位置から、開閉バー１２を復帰させるための復帰機構について説明する。図２に示すように、アーム１０の本体６に面する面２０には、本体６の回転軸８（図３（ｂ）参照）に係合する取り付け孔２２を有し、これによりアーム１０は回転軸８の回転に伴って本体６に対して回転する。一方、開閉バー１２を固定保持するバーホルダ１４は、回動軸１６回りに回動可能となるようにアーム８に枢着されており、少なくとも、開閉バー１２が回転軸８の方向に略垂直に延びる通常角度位置（図２の状態）と、開閉バー１２が回転軸８の方向に略平行に延びるリリース位置（図１（ｃ）の状態）との間を（すなわち少なくとも約９０度）回動可能である。またアーム１０は、面２０から本体６側に突出する突出部材２４を有する。   Next, a return mechanism for returning the open / close bar 12 from the release position shown in FIG. As shown in FIG. 2, the surface 20 of the arm 10 facing the main body 6 has a mounting hole 22 that engages with the rotation shaft 8 (see FIG. 3B) of the main body 6, whereby the arm 10 is As the rotary shaft 8 rotates, it rotates relative to the main body 6. On the other hand, the bar holder 14 that fixes and holds the opening / closing bar 12 is pivotally attached to the arm 8 so as to be rotatable about the rotation shaft 16, and at least the opening / closing bar 12 is substantially perpendicular to the direction of the rotation shaft 8. Rotates between the extended normal angular position (state shown in FIG. 2) and the release position (state shown in FIG. 1C) where the open / close bar 12 extends substantially parallel to the direction of the rotation shaft 8 (ie, at least about 90 degrees). Is possible. Further, the arm 10 has a protruding member 24 that protrudes from the surface 20 toward the main body 6 side.

次に、開閉バー１２をリリース状態から復帰させるまでの動作を、図３〜図５を参照して説明する。図３（ａ）は、開閉バー１２がリリース位置にあるとき（図１（ｃ））の発進制御機２を、車両進行方向（矢印１８）にみた外観側面図であり、図３（ｂ）は図３（ａ）のＡ−Ａ断面を示す図である。図２に示した突出部材２４は、図３（ｂ）に示すように本体６に接離する方向（図３（ｂ）では上下方向）に可動に構成されている。突出部材２４は、後述する本体６上の凸部４０に乗り上げて変位する関係上、曲面を有することが好ましく、図示例では円板状部材として形成されているが、球状又は半球状の部材としてもよい。   Next, the operation until the opening / closing bar 12 is returned from the released state will be described with reference to FIGS. FIG. 3 (a) is an external side view of the start controller 2 when the open / close bar 12 is in the release position (FIG. 1 (c)) in the vehicle traveling direction (arrow 18). These are figures which show the AA cross section of Fig.3 (a). The protruding member 24 shown in FIG. 2 is configured to be movable in a direction in which the protruding member 24 comes into contact with and separates from the main body 6 (up and down direction in FIG. 3B) as shown in FIG. 3B. The projecting member 24 preferably has a curved surface because it rides on a convex portion 40 on the main body 6 to be described later and is displaced. In the illustrated example, the projecting member 24 is formed as a disk-shaped member, but as a spherical or hemispherical member. Also good.

突出部材２４は、図３（ｂ）の破線内に示すようなカム及びラッチを利用したロック機構に関連付けられており、具体的には、アーム１０の内部にて第１枢軸２６回りに回転可能に設けられた第１ラッチ２８の一端に接続されている。第１枢軸２６に関して第１ラッチ２８の一端と反対側の他端は、アーム１０内部をその長手方向に延びるように配置されたリンク部材３０を係止するようになっており、具体的にはリンク部材３０に設けたピン状部材３２を係止する。リンク部材３０は、第１枢軸２６に係合する長孔３４を有しており、これによりアーム１０内部をその長手方向に変位可能である。さらにリンク部材３０は、その変位によってバーホルダ１４がアーム１０に対して回動軸１６回りに回動できるようになっている。詳細には、リンク部材３０の一端はバーホルダ１４と実質一体のタブ状部材３６に、第２枢軸３８を介して枢着されている。但し、図３（ｂ）に示すように第１ラッチ２８がピン状部材３２を係止している間は、リンク部材３０はバーホルダ１４をアーム１０に対して回動させるように変位（図３（ｂ）では右側に変位）できないので、開閉バー１２はリリース位置に保持されている。   The protruding member 24 is associated with a locking mechanism using a cam and a latch as shown in a broken line in FIG. 3B, and specifically, can rotate around the first pivot 26 inside the arm 10. Is connected to one end of a first latch 28 provided in the first latch 28. The other end opposite to one end of the first latch 28 with respect to the first pivot 26 is adapted to lock a link member 30 arranged so as to extend in the longitudinal direction inside the arm 10. The pin-shaped member 32 provided on the link member 30 is locked. The link member 30 has a long hole 34 that engages with the first pivot 26, so that the inside of the arm 10 can be displaced in the longitudinal direction. Further, the link member 30 is configured so that the bar holder 14 can be rotated around the rotation axis 16 with respect to the arm 10 by the displacement. Specifically, one end of the link member 30 is pivotally attached to a tab-like member 36 that is substantially integral with the bar holder 14 via a second pivot 38. However, as shown in FIG. 3B, while the first latch 28 is locking the pin-like member 32, the link member 30 is displaced so as to rotate the bar holder 14 with respect to the arm 10 (FIG. 3). (B) cannot be displaced to the right), so the open / close bar 12 is held in the release position.

図４（ａ）は、復帰動作を開始したとき（後述する図６（ｃ）参照）の発進制御機２を、車両進行方向（矢印１８）にみた外観側面図であり、図４（ｂ）は図４（ａ）のＢ−Ｂ断面を示す図である。図４（ａ）に示すように、開閉バー１２がリリース位置にある状態のまま、アーム１０が本体６に対して（例えば図３の状態から８０度）回転していくと、図４（ｂ）の破線内に示すように、アーム１０に設けた突出部材２４が、本体６の側面に設けた凸部４０に乗り上げるように係合する。なお凸部４０は、復帰動作中に突出部材２４をアーム１０に対して変位させることができるものであればどのような形状でもよいが、より円滑な動作のためにスロープ状とすることが好ましい。突出部材２４の変位により、突出部材２４に接続された第１ラッチ２８が第１枢軸２６について（図示例では反時計回りに）回転し、第１ラッチ２８がリンク部材３０のピン状部材３２から離隔し、開閉バー１２をリリース位置に保持するロック機構は解除された状態となる。但しこの状態では、バーホルダ１４（開閉バー１２）はアーム１０に対して回動可能な状態ではあるが、開閉バー１２はその自重等によってリリース位置に維持されている。   4A is an external side view of the start controller 2 when the return operation is started (see FIG. 6C described later) in the vehicle traveling direction (arrow 18). FIG. These are figures which show the BB cross section of Fig.4 (a). As shown in FIG. 4A, when the arm 10 rotates with respect to the main body 6 (for example, 80 degrees from the state of FIG. 3) while the open / close bar 12 is in the release position, FIG. ), The protruding member 24 provided on the arm 10 is engaged so as to ride on the convex portion 40 provided on the side surface of the main body 6. The convex portion 40 may have any shape as long as it can displace the protruding member 24 with respect to the arm 10 during the returning operation, but it is preferable to have a slope shape for a smoother operation. . Due to the displacement of the projecting member 24, the first latch 28 connected to the projecting member 24 rotates about the first pivot 26 (counterclockwise in the illustrated example), and the first latch 28 moves from the pin-shaped member 32 of the link member 30. The locking mechanism that separates and holds the open / close bar 12 in the release position is released. However, in this state, the bar holder 14 (opening / closing bar 12) is in a state of being rotatable with respect to the arm 10, but the opening / closing bar 12 is maintained at the release position by its own weight or the like.

図５（ａ）は、復帰動作が完了したとき（後述する図６（ｅ）参照）の発進制御機２を、車両進行方向（矢印１８）にみた外観側面図であり、図５（ｂ）は図５（ａ）のＣ−Ｃ断面を示す図である。図５（ａ）等に示すように、本体６の上部には、復帰動作中は常時、開閉バー１２又はバーホルダ１４に当接して開閉バー１２をリリース位置から徐々に通常の位置（開位置）に戻すように案内するガイド部材４２が設けられている。すなわちガイド部材４２は、予め定めたアーム１０の復帰動作角度範囲内（例えば８５度〜９５度）において、復帰動作開始時（アーム回転角８５度）から復帰動作完了時（アーム回転角９５度）まで開閉バー１２又はバーホルダ１４に当接して、復帰動作完了時には開閉バー１２がバーホルダ１４に対して略９０度回動（図５（ｂ））の状態となるように開閉バー１２を案内するように設計されている。   FIG. 5A is an external side view of the start controller 2 when the return operation is completed (see FIG. 6E described later) in the vehicle traveling direction (arrow 18). These are figures which show the CC cross section of Fig.5 (a). As shown in FIG. 5 (a) and the like, the upper portion of the main body 6 is always in contact with the opening / closing bar 12 or the bar holder 14 during the return operation so that the opening / closing bar 12 is gradually moved from the release position to the normal position (open position). A guide member 42 is provided for guiding to return to the position. That is, the guide member 42 is within a predetermined return operation angle range of the arm 10 (for example, 85 degrees to 95 degrees), from the start of the return operation (arm rotation angle 85 degrees) to the completion of the return operation (arm rotation angle 95 degrees). The opening / closing bar 12 or the bar holder 14 until the opening / closing bar 12 is guided so that the opening / closing bar 12 is rotated about 90 degrees (FIG. 5B) with respect to the bar holder 14 when the return operation is completed. Designed to.

ガイド部材４２の形状は、復帰動作中に常時開閉バー１２又はバーホルダ１４に当接し、駆動軸８の回転に従って、バーホルダ１４に対する開閉バー１２の姿勢をリリース位置から開位置に変更できる限りにおいてどのような形状でもよいが、通常は、図５（ａ）等に示すように、鉛直方向について、閉位置にある開閉バー１２と反対側に傾斜している直線状又は曲線状のガイド部分を有する部材である。ガイド部材がこのような形状であると、ガイド部材４２のガイド部分に当接している開閉バー１２を保持するバーホルダ１４には、アーム１０に対する回動角を９０度（リリース位置）からゼロ度（通常位置）に変化させるような力（少なくとも分力）が作用するので、復帰動作のための駆動源を別途用意せずとも、開閉バーの姿勢をリリース位置から開位置に変更できる。   The shape of the guide member 42 is not limited as long as the guide member 42 is always in contact with the open / close bar 12 or the bar holder 14 during the return operation and the posture of the open / close bar 12 with respect to the bar holder 14 can be changed from the release position to the open position according to the rotation of the drive shaft 8. However, normally, as shown in FIG. 5A and the like, a member having a linear or curved guide portion that is inclined in the vertical direction on the opposite side of the open / close bar 12 in the closed position. It is. When the guide member has such a shape, the bar holder 14 that holds the open / close bar 12 that is in contact with the guide portion of the guide member 42 has a rotation angle with respect to the arm 10 of 90 degrees (release position) to zero degrees ( Since a force (at least a component force) that changes to the normal position) acts, the posture of the open / close bar can be changed from the release position to the open position without separately preparing a drive source for the return operation.

またガイド部材４２は、開閉バー１２と当接・摺動する関係上、開閉バー１２との接触面積を低減すべく、円柱・円筒等の、曲面の外表面を有することが好ましく、例えばパイプ部材により作製可能である。またガイド部材４２と当接する開閉バー１２の部位には、ガイド部材４２との摩擦をより低減すべく、自由回転可能なローラ等を設け、ガイド部材４２と開閉バー１２との接触面積を減らすとともに、ガイド部材４２と開閉バー１２との摩擦を摺動摩擦ではなく転がり摩擦となるようにしてもよい。さらに、ローラ等を用いた場合にその効果を十分に生かすべく、ガイド部材４２は復帰動作中は常に該ローラに当接するような形状に構成される。このようなガイド部材４２の形状は、開閉バー１２やバーホルダ１４の各部の寸法から幾何学的に計算して求めることができる。   In addition, the guide member 42 preferably has a curved outer surface such as a cylinder or a cylinder in order to reduce the contact area with the opening / closing bar 12 in terms of contact / sliding with the opening / closing bar 12. Can be produced. In addition, in order to further reduce the friction with the guide member 42, a roller or the like that can freely rotate is provided at a portion of the open / close bar 12 that contacts the guide member 42, thereby reducing the contact area between the guide member 42 and the open / close bar 12. The friction between the guide member 42 and the opening / closing bar 12 may be rolling friction instead of sliding friction. Further, in order to make full use of the effect when a roller or the like is used, the guide member 42 is configured to be in contact with the roller during the return operation. Such a shape of the guide member 42 can be obtained by geometrically calculating from the dimensions of the respective parts of the open / close bar 12 and the bar holder 14.

図５の例では、復帰開始時（図４（ａ））のアーム１０（回転軸８）の回転角度を８５度とし、復帰完了時（図５（ａ））の回転角度を９５度としているが、これは一例である。例えば、復帰動作開始時の角度をより小さくしてもよいが、安全上、開閉バー１２が復帰動作中に車両通行空間内に進入しないようにすることが望まれ、その意味では復帰動作開始時のアーム回転角は好ましくは７５度以上、より好ましくは８０度以上、さらに好ましくは８５度以上である。なお復帰動作開始時のアーム回転角度最適値は、車両通行空間の形状に応じて決定できる。また復帰動作完了時のアーム１０の回転角は、通常の開位置となる角度（例えば８５．５度）よりもいくらか大きくすることが好ましく、例えば９０度〜１２５度の範囲から選定することが好ましい。このような復帰動作開始時や復帰動作完了時の角度位置の変更は、ガイド部材４２の形状変更により容易に行うことができる。   In the example of FIG. 5, the rotation angle of the arm 10 (rotating shaft 8) at the start of return (FIG. 4A) is 85 degrees, and the rotation angle at the completion of return (FIG. 5A) is 95 degrees. But this is an example. For example, the angle at the start of the return operation may be made smaller. However, for safety reasons, it is desired that the opening / closing bar 12 does not enter the vehicle passage space during the return operation. The arm rotation angle is preferably 75 degrees or more, more preferably 80 degrees or more, and still more preferably 85 degrees or more. Note that the optimum value of the arm rotation angle at the start of the return operation can be determined according to the shape of the vehicle traffic space. Further, the rotation angle of the arm 10 when the return operation is completed is preferably somewhat larger than an angle (for example, 85.5 degrees) that is a normal open position, and is preferably selected from a range of 90 degrees to 125 degrees, for example. . Such change of the angular position at the start of the return operation or completion of the return operation can be easily performed by changing the shape of the guide member 42.

上述のように図５は、復帰動作完了時を示しているが、バーホルダ１４とアーム１０との位置関係は通常の開閉動作時のものと等しい。ここで通常動作時は、開閉バー１２に車両が接触する等の衝撃が加わらない限り、開閉バー１２が容易にリリース位置に移動しないようにする必要がある。そこで本実施形態では、図５（ｂ）の破線内に示すように、バーホルダ１４を通常位置に保持する掛止機構が設けられる。詳細には、リンク部材３０が連結されるタブ状部材３６に第２ラッチ４４を設け、開閉バー１２（バーホルダ１４）が通常位置にあるときは第２ラッチ４４がストッパ部材４６に掛止される。ストッパ部材４６は図示例では、平行配置された略同一形状の２つの板状部材４８の間を延びるピン状部材であり、板状部材４８及びピン状部材４６は一体的に、アーム１０内に設けた第３枢軸５０回りに回転可能になっている。板状部材４８は、スプリング５２によってバーホルダ１４の回動方向（時計回り方向）に付勢されており、さらに板状部材４８に設けた切り欠き５４とアーム１０内部に固定した突出部（図示例ではピン状部材）５６とが係合することにより、通常は図５（ｂ）に示す位置に保持されている。   As described above, FIG. 5 shows the time when the return operation is completed, but the positional relationship between the bar holder 14 and the arm 10 is the same as that during the normal opening / closing operation. Here, during normal operation, it is necessary to prevent the opening / closing bar 12 from easily moving to the release position unless an impact such as a vehicle coming into contact with the opening / closing bar 12 is applied. Therefore, in the present embodiment, as shown in the broken line in FIG. 5B, a latching mechanism that holds the bar holder 14 in the normal position is provided. Specifically, the second latch 44 is provided on the tab-like member 36 to which the link member 30 is connected, and the second latch 44 is hooked to the stopper member 46 when the opening / closing bar 12 (bar holder 14) is in the normal position. . In the illustrated example, the stopper member 46 is a pin-like member extending between two plate-like members 48 having substantially the same shape and arranged in parallel. The plate-like member 48 and the pin-like member 46 are integrally formed in the arm 10. It is rotatable around the third pivot 50 provided. The plate-like member 48 is urged in the rotating direction (clockwise direction) of the bar holder 14 by a spring 52, and further, a notch 54 provided in the plate-like member 48 and a protruding portion (in the illustrated example) fixed inside the arm 10. In this case, the pin-like member 56 is normally engaged with the pin-like member 56 so as to be held at the position shown in FIG.

ここで、開閉バー１２が閉位置にあるとき（従ってアーム１０とバーホルダ１４との位置関係は図５（ｂ）と同等）に、車両等が接触して一定以上の負荷が開閉バー１２に作用すると、バーホルダ１４のタブ状部材３６には回動軸１６回りにリリース位置に向けて（反時計回りに）回転しようとする力が作用し、該力がスプリング５２の付勢力に逆らって板状部材４８を第３枢軸５０回りに回転させ、これによりピン状部材４６と第２ラッチ４４とが掛止しなくなり、バーホルダ１４及び開閉バー１２が図４（ｂ）に示すようなリリース位置に移動する。スプリング５２のバネ定数を適宜設定することにより、どの程度以上の力が開閉バー１２に作用したときに開閉バー１２がリリース位置に移動するかを設定できる。   Here, when the open / close bar 12 is in the closed position (therefore, the positional relationship between the arm 10 and the bar holder 14 is the same as that shown in FIG. 5B), a vehicle or the like comes into contact and a load exceeding a certain level acts on the open / close bar 12. Then, a force to rotate around the rotation shaft 16 toward the release position (counterclockwise) acts on the tab-like member 36 of the bar holder 14, and the force is plate-like against the urging force of the spring 52. The member 48 is rotated around the third pivot 50, whereby the pin-like member 46 and the second latch 44 are not latched, and the bar holder 14 and the open / close bar 12 are moved to the release position as shown in FIG. 4B. To do. By appropriately setting the spring constant of the spring 52, it is possible to set how much force is applied to the open / close bar 12 when the open / close bar 12 moves to the release position.

図６は、上述の復帰機構を有する発進制御機２の復帰動作を、模式的に説明する図である。先ず図６（ａ）は、図１（ａ）同様、開閉バー１２が閉位置にある状態を示している。次に図６（ｂ）は、図１（ｃ）同様、開閉バー１２が車両接触等の理由により、リリース位置に移動した状態を示している。   FIG. 6 is a diagram schematically illustrating the return operation of the start controller 2 having the above-described return mechanism. First, FIG. 6A shows a state where the open / close bar 12 is in the closed position, as in FIG. Next, FIG.6 (b) has shown the state which the opening-and-closing bar 12 moved to the release position for reasons, such as vehicle contact, like FIG.1 (c).

次の図６（ｃ）は、図４に相当し、開閉バー１２の復帰動作開始時、すなわちアーム１０が所定角度（例えば８０度）回転し、開閉バー１２がガイド部材４２に当接した状態を示している。この状態では、開閉バー１２がガイド部材４２に当接すると略同時に、図４（ｂ）に示したように、ロック機構が解除されてバーホルダ１４がリリース位置から通常の位置に回動可能な状態となる。   Next, FIG. 6C corresponds to FIG. 4, and when the opening / closing bar 12 starts the return operation, that is, the arm 10 is rotated by a predetermined angle (for example, 80 degrees), and the opening / closing bar 12 is in contact with the guide member 42. Is shown. In this state, as shown in FIG. 4B, the lock mechanism is released and the bar holder 14 can be rotated from the release position to the normal position as shown in FIG. It becomes.

図６（ｄ）は、復帰動作中の状態（例えばアーム１０が９０度回転した状態）、換言すれば図４と図５の間の状態に相当する状態を示している。上述のように復帰動作中はガイド部材４２と開閉バー１２又はバーホルダ１４とは常時当接しており、アーム１０の回転に伴って、ガイド部材４２から受ける力によって開閉バー１２がリリース位置から開位置へ徐々に移動し（案内され）ていく。   FIG. 6D shows a state during the return operation (for example, a state in which the arm 10 is rotated 90 degrees), in other words, a state corresponding to the state between FIG. 4 and FIG. As described above, the guide member 42 is always in contact with the open / close bar 12 or the bar holder 14 during the return operation, and the open / close bar 12 is opened from the release position by the force received from the guide member 42 as the arm 10 rotates. Gradually move to (guided).

最後に、図５に概ね相当する図６（ｅ）に示すように、アーム１０が所定角度（例えば１２５度）回転すると、開閉バー１２が通常の状態、すなわちアーム１０の長手方向と略同一方向に延びる状態に保持され、復帰動作が完了する。   Finally, as shown in FIG. 6 (e), which roughly corresponds to FIG. 5, when the arm 10 is rotated by a predetermined angle (for example, 125 degrees), the open / close bar 12 is in a normal state, that is, substantially in the same direction as the longitudinal direction of the arm 10. The return operation is completed.

図示していないが、本発明に係る発進制御機２には、開閉バー１２がリリース位置に移動したことを検知する検知手段や、開閉バー１２がリリース位置に移動したことを該検知手段が検知したときに、発進制御機２から離れたブース内等に居る作業者にアラームを発するアラーム手段を設けることができる。また上述の復帰動作は、アラームを受けた作業者がブース内等から遠隔操作にて発進制御機２に指示して行ってもよいし、上記検知手段の検知結果に基づいて発進制御機２が、作業者の指示を待たずに自動で行ってもよい。   Although not shown, in the start controller 2 according to the present invention, the detection means for detecting that the opening / closing bar 12 has moved to the release position, or the detection means for detecting that the opening / closing bar 12 has moved to the release position is detected. When it does, the alarm means which issues an alarm to the worker who exists in the booth away from the start control machine 2, etc. can be provided. Further, the returning operation described above may be performed by an operator who has received an alarm instructing the start controller 2 by remote control from within the booth or the like, and the start controller 2 may be operated based on the detection result of the detecting means. It may be performed automatically without waiting for the operator's instruction.

上述の実施形態では、開閉バー１２はバーホルダ１４を介してアーム１０に接続されているが、バーホルダ１４を省略して直接、アーム１０に対して回動可能に取り付けることも可能である。またガイド部材４２は本体６の上部に設けられているが、本体６に直接設けられる必要はなく、例えば本体６の近傍に別途自立するように設けてもよい。   In the above-described embodiment, the open / close bar 12 is connected to the arm 10 via the bar holder 14. However, the bar holder 14 may be omitted and directly attached to the arm 10 so as to be rotatable. In addition, the guide member 42 is provided on the upper portion of the main body 6, but it is not necessary to be provided directly on the main body 6.

本発明では、リリース位置からの開閉バー１２の復帰動作を行う際、アーム１０の回転動作のための（サーボモータ等の）駆動源以外の駆動源や駆動機構を必要としない。換言すれば、発進制御機２に設ける駆動源はアーム１０を回転させるためのもののみとすることができる。従って本発明によれば、開閉バーの復帰動作を自動で行える構成でありながら、構成要素の少ないコンパクトで低コストの発進制御機が提供される。   In the present invention, when the opening / closing bar 12 is returned from the release position, no drive source or drive mechanism other than the drive source (such as a servo motor) for rotating the arm 10 is required. In other words, the drive source provided in the start controller 2 can be only for rotating the arm 10. Therefore, according to the present invention, there is provided a compact and low-cost start controller having a small number of components, while having a configuration in which the opening / closing bar can be automatically restored.
