Description

この発明は、エスカレータ、動く歩道などの乗降口の床部に設けられているマンコンベアの乗降口安全装置に関するものである。   The present invention relates to an entrance / exit safety device for a man conveyor provided on a floor of an entrance / exit such as an escalator or a moving sidewalk.

従来のマンコンベアの乗降口安全装置では、踏段側の端部にコムが取り付けられ、床部側の両側部の下面が支持ボルトに支持されて、支持ボルトの先端を支点として踏段側の端部が上方向に移動可能に配設されたコムプレートと、このコムプレートの踏段側の両側部に設けられ、コムプレートの踏段側を下方向に付勢するばねと、コムプレートの踏段側の両側部に設けられた検知レバーと、検知レバーの当接によりコムプレートの踏段側の上方への移動を検知する検知スイッチと、検知スイッチの検知後にコムプレートに当接してコムプレートのそれ以上の回動を阻止するストッパと、を備え、コムプレートが支持ボルトの先端を支点として上方に回転して、検知レバーが検知スイッチを作動させてマンコンベアを停止させていた（例えば、特許文献１参照）。   In conventional entrance / exit safety devices for man conveyors, a comb is attached to the end on the step side, the lower surfaces of both sides on the floor side are supported by support bolts, and the end on the step side with the tip of the support bolt as a fulcrum Is disposed on both sides of the step side of the comb plate, the spring for biasing the step side of the comb plate downward, and both sides of the step side of the comb plate A detection lever provided at the center, a detection switch that detects the upward movement of the comb plate on the step side by the contact of the detection lever, and a further contact of the comb plate after the detection of the detection switch.

特開平１１−１７１４５７号公報Japanese Patent Laid-Open No. 11-171457

従来のマンコンベアの乗降口安全装置では、異物がコムと踏段との間に挟み込まれると、コムプレートが支持ボルトの先端を支点として上方に回動し、検知レバーが検知スイッチを作動させる。そして、検知レバーが検知スイッチを作動させた後、コムプレートはストッパに当接してそれ以上の回動が阻止される。しかし、検知スイッチが作動してからマンコンベアが停止するまでに僅かな時間を要する。そこで、マンコンベアが停止するまでの僅かな時間に踏段が移動し、異物がコムと踏段との間にさらに食い込む。これにより、コムプレートと踏段とによる異物の挟み込み力が過度に増大し、異物、コムプレート、踏段などが損傷するという課題があった。   In the conventional entrance / exit safety device for a man conveyor, when a foreign object is sandwiched between the comb and the step, the comb plate rotates upward with the tip of the support bolt as a fulcrum, and the detection lever operates the detection switch. Then, after the detection lever operates the detection switch, the comb plate comes into contact with the stopper to prevent further rotation. However, it takes a short time until the man conveyor stops after the detection switch is activated. Therefore, the step moves in a short time until the man conveyor stops, and foreign matter further penetrates between the comb and the step. Thereby, the pinching force of the foreign material by a comb plate and a step increases excessively, and the subject that a foreign material, a comb plate, a step, etc. were damaged occurred.

この発明は、上記課題を解決するためになされたもので、異物の挟み込み検知後に検知レバーのコアプレートの回動動作との連動を解除させ、異物の挟み込み検知からマンコンベアの停止までのタイムラグの間における異物のさらなる食い込みにともなうコムプレートの回動を可能として、異物、コムプレート、踏段などの損傷を防止できるマンコンベアの乗降口安全装置を得ることを目的とする。   The present invention has been made to solve the above-mentioned problem.After detecting the foreign object pinching, the interlocking with the rotation operation of the core plate of the detection lever is released, and the time lag from the detection of the foreign object pinching to the stop of the man conveyor is reduced. It is an object of the present invention to provide a man conveyor entrance safety device that enables rotation of the comb plate with further penetration of foreign matter between them and prevents damage to foreign matter, comb plates, steps, and the like.

この発明のマンコンベアの乗降口安全装置は、マンコンベアの乗降口の踏段側に配設され、前記踏段との間への異物の挟み込みにより、前記踏段と反対側の端部側を回動中心として、前記踏段側の端部が持ち上がるように回動するコムプレートと、前記コムプレートの幅方向の一側に配設され、前記コムプレートから前記踏段の方向に突出した状態で、前記コムプレートの回動動作に連動して回動する検知レバーと、前記検知レバーの回動動作により作動して、前記コムプレートと前記踏段との間への前記異物の挟み込みを検知する検知スイッチと、前記検知スイッチの作動後に前記検知レバーと当接し、前記検知レバーのそれ以上の回動を阻止する第１ストッパと、を備え、前記検知レバーは、前記第１ストッパに当接した後に、前記コムプレートの回動動作との連動が解除されるように構成されている。   The entrance / exit safety device for a man conveyor according to the present invention is disposed on the step side of the entrance / exit of the man conveyor, and the center of the end opposite to the step is rotated by a foreign object sandwiched between the steps. A comb plate that rotates so that an end on the step side is lifted, and is disposed on one side in the width direction of the comb plate, and protrudes in the direction of the step from the comb plate A detection lever that rotates in conjunction with the rotation operation of the detection lever, a detection switch that operates by the rotation operation of the detection lever, and detects the inclusion of the foreign matter between the comb plate and the step; A first stopper that abuts on the detection lever after the operation of the detection switch and prevents further rotation of the detection lever, and the detection lever contacts the first stopper and then the comb Integration with rotation of rate is configured to be released.

この発明によれば、検知レバーは、第１ストッパに当接した後に、コムプレートの回動動作との連動が解除される。そこで、検知レバーの作動からマンコンベアの停止までのタイムタグの間に、異物がコムプレートと踏段との間にさらに食い込んでも、異物の食い込み量の増大とともにコアプレートが回動する。そこで、コムプレートと踏段とによる異物の挟み込み力が過度に増大することがなく、異物、踏段、コムプレートなどの損傷の発生が抑制される。   According to the present invention, after the detection lever comes into contact with the first stopper, the interlock with the rotational movement of the comb plate is released. Therefore, even if a foreign object bites further between the comb plate and the step during the time tag from the operation of the detection lever to the stop of the man conveyor, the core plate rotates as the foreign material bite amount increases. Therefore, the foreign matter pinching force between the comb plate and the step does not increase excessively, and the occurrence of damage to the foreign matter, step, comb plate, etc. is suppressed.

図１から図３において、マンコンベアは、踏段チェン(図示せず）を介して無端状に連結された多数個の踏段４が、フレーム１に立設された左右の欄干（図示せず）の下部スカートガード２の間に配設され、回転駆動装置（図示せず）により循環移動する。さらに、欄干の外周に配設された移動手摺３が、踏段４の循環移動と同期して周回移動し、乗客を下階から上階に、あるいは上階から下階に運搬するようになっている。乗降口には、床板５に隣接してコムプレート６が配設されている。そして、コム７がコムプレート６の踏段４側に締着固定されている。ここで、マンコンベアの骨格構造体であるトラスおよびトラスに取り付けられた支持部材をフレーム１としている。   1 to 3, the man conveyor includes a plurality of steps 4 connected endlessly via a step chain (not shown), and left and right railings (not shown) erected on the frame 1. It arrange | positions between the lower skirt guards 2, and it circulates and moves by a rotation drive device (not shown). Furthermore, the moving handrail 3 disposed on the outer periphery of the balustrade moves around in synchronism with the circulating movement of the step 4 and carries passengers from the lower floor to the upper floor or from the upper floor to the lower floor. Yes. A comb plate 6 is disposed adjacent to the floor board 5 at the entrance / exit. The comb 7 is fastened and fixed to the step 4 side of the comb plate 6. Here, a truss that is a skeleton structure of a man conveyor and a support member attached to the truss are used as a frame 1.

コムプレート６の踏段４と反対側の端部が、軸方向を踏段４の移動方向と直交し、かつ水平とする第１軸８によりフレーム１に連結されている。これにより、コムプレート６が、第１軸８を回動中心として、回動可能にフレーム１に取り付けられている。ボルト９が、コムプレート６を貫通して、フレーム１に連結されている。コムプレート用ストッパ１０は、円筒部の一側開口を底部で塞口した有底円筒状に構成され、ボルト９が底部の中心位置を貫通し、かつ底部をボルト９の頭部９ａに向けて、頭部９ａとフレーム１との間に、ボルト９の長さ方向に移動可能に装着されている。第１ばね１１が、コムプレート用ストッパ１０の底部とコムプレート６との間に配設され、コムプレート用ストッパ１０の底部をボルト９の頭部９ａに押圧している。これにより、コムプレート６は、第１ばね１１の付勢力により、図２中第１軸８周りに反時計回りに回動し、ボルト９のフレーム１との連結部に当接して、通常状態となっている。   The end of the comb plate 6 opposite to the step 4 is connected to the frame 1 by a first shaft 8 whose axial direction is orthogonal to the moving direction of the step 4 and is horizontal. Thereby, the comb plate 6 is attached to the frame 1 so as to be rotatable about the first shaft 8 as a rotation center. A bolt 9 passes through the comb plate 6 and is connected to the frame 1. The comb plate stopper 10 is formed in a bottomed cylindrical shape in which one side opening of the cylindrical portion is closed at the bottom, the bolt 9 passes through the center of the bottom, and the bottom faces the head 9 a of the bolt 9. The head 9 a and the frame 1 are mounted so as to be movable in the length direction of the bolt 9. The first spring 11 is disposed between the bottom of the comb plate stopper 10 and the comb plate 6, and presses the bottom of the comb plate stopper 10 against the head 9 a of the bolt 9. As a result, the comb plate 6 is rotated counterclockwise around the first shaft 8 in FIG. 2 by the biasing force of the first spring 11 and is in contact with the connecting portion of the bolt 9 with the frame 1 to be in a normal state. It has become.

検知レバー１２は、コムプレート６の幅方向の一側の側部に形成されたピン孔に、検知レバー１２の踏段４と反対側の端部を貫通したピン１３を挿入して、コムプレート６の側部に連結されている。これにより、検知レバー１２は、コムプレート６から踏段４側に突出した状態で、第１軸８を回動中心とするコムプレート６の回動動作に連動して回動可能となっている。ピン１３は、過度の荷重により折損する材料で作製されている。検知スイッチ１５は、通常状態の検知レバー１２の突出端との間に微少な隙間をあけてフレーム１に取り付けられ、コムプレート６の回動動作に連動して回動する検知レバー１２に押圧されて、作動するようになっている。第１ストッパ１６が、回動する検知レバー１２に当接して、検知レバー１２による検知スイッチ１５のストローク量を規制するように、フレーム１に取り付けられている。なお、コムプレート６の幅方向とは、第１軸８の軸方向と平行な方向である。   The detection lever 12 is inserted into a pin hole formed on one side of the comb plate 6 in the width direction by inserting a pin 13 penetrating the end of the detection lever 12 on the side opposite to the step 4. It is connected to the side part. Thereby, the detection lever 12 is rotatable in conjunction with the rotation operation of the comb plate 6 with the first shaft 8 as the rotation center in a state of protruding from the comb plate 6 toward the step 4 side. The pin 13 is made of a material that breaks due to an excessive load. The detection switch 15 is attached to the frame 1 with a slight gap between the detection switch 12 and the protruding end of the detection lever 12 in the normal state, and is pressed by the detection lever 12 that rotates in conjunction with the rotation operation of the comb plate 6. It is designed to work. The first stopper 16 is attached to the frame 1 so as to abut the rotating detection lever 12 and regulate the stroke amount of the detection switch 15 by the detection lever 12. The width direction of the comb plate 6 is a direction parallel to the axial direction of the first shaft 8.

つぎに、乗降口安全装置の動作を図４および図５を参照しつつ説明する。   Next, the operation of the entrance / exit safety device will be described with reference to FIGS. 4 and 5. FIG.

マンコンベアの運転時に、踏段４上の異物１７がコム７と踏段４との間に挟み込まれると、図４に示されるように、コムプレート６が第１ばね１１を収縮させつつ、第１軸８を回動中心として時計回りに回動し、コム７側が持ち上がる。検知レバー１２がコムプレート６の回動動作に連動して回動し、検知レバー１２の突出端が検知スイッチ１５を押圧する。そして、検知スイッチ１５が作動し、マンコンベアが直ちに停止される。   When the foreign material 17 on the step 4 is sandwiched between the comb 7 and the step 4 during the operation of the man conveyor, the comb plate 6 contracts the first spring 11 and the first shaft 11 as shown in FIG. Rotate clockwise around 8 as the center of rotation and lift the comb 7 side. The detection lever 12 rotates in conjunction with the rotation operation of the comb plate 6, and the protruding end of the detection lever 12 presses the detection switch 15. Then, the detection switch 15 is activated and the man conveyor is immediately stopped.

しかし、検知スイッチ１５が作動してからマンコンベアが停止されるまでには、タイムラグがある。このタイムラグの間に踏段４が移動し、異物１７がコム７と踏段４との間にさらに食い込むことになる。   However, there is a time lag after the detection switch 15 is activated until the man conveyor is stopped. During this time lag, the step 4 moves, and the foreign matter 17 further bites between the comb 7 and the step 4.

このとき、コムプレート６は、コム７と踏段４との間の異物１７の食い込み量の増大に連動して、第１軸８周りにさらに回動する。同時に、検知レバー１２が、コムプレート６の回動動作に連動して回動する。そして、検知レバー１２が第１ストッパ１６に当接し、検知スイッチ１５へのそれ以上の押圧が阻止される。コムプレート６がさらに回動すると、検知レバー１２の回動を阻止する荷重が、第１ストッパ１６により発生する。そこで、検知レバー１２に作用する荷重が、ピン１３の折損荷重を超えると、図５に示されるように、ピン１３が折損し、検知レバー１２とコムプレート６との連結が解除される。すなわち、検知レバー１２の、コムプレート６の回動動作との連動が解除される。   At this time, the comb plate 6 further rotates around the first shaft 8 in conjunction with an increase in the amount of foreign matter 17 between the comb 7 and the step 4. At the same time, the detection lever 12 rotates in conjunction with the rotation operation of the comb plate 6. And the detection lever 12 contact | abuts to the 1st stopper 16, and the further press to the detection switch 15 is blocked | prevented. When the comb plate 6 further rotates, a load that prevents the detection lever 12 from rotating is generated by the first stopper 16. Therefore, when the load acting on the detection lever 12 exceeds the breakage load of the pin 13, the pin 13 is broken and the connection between the detection lever 12 and the comb plate 6 is released as shown in FIG. That is, the interlocking of the detection lever 12 with the turning operation of the comb plate 6 is released.

このように、この乗降口安全装置によれば、検知スイッチ１５が作動してからマンコンベアが停止されるまでのタイムラグの間においても、コムプレート６は、コム７と踏段４との間の異物１７の食い込み量の増大に連動して、コム７側がさらに持ち上がるように回動する。そこで、コム７と踏段４とによる異物１７の挟み込み力が過度に増大することがなく、踏段４、コムプレート６およびコム７の損傷の発生が抑制される。また、異物１７がコム７と踏段４と間に挟み込まれた異物１７の取り出しが容易となる。   Thus, according to this entrance / exit safety device, even during the time lag from when the detection switch 15 is actuated until the man conveyor is stopped, the comb plate 6 has a foreign object between the comb 7 and the step 4. In conjunction with the increase in the amount of biting 17, the comb 7 is rotated so as to be further lifted. Therefore, the pinching force of the foreign matter 17 between the comb 7 and the step 4 does not increase excessively, and the occurrence of damage to the step 4, the comb plate 6 and the comb 7 is suppressed. In addition, it is easy to take out the foreign matter 17 in which the foreign matter 17 is sandwiched between the comb 7 and the step 4.

また、検知スイッチ１５を作動させるストローク量が第１ストッパ１６により規定されているので、検知レバー１２が検知スイッチ１５を過度に押圧することに起因する検知スイッチ１５の損傷の発生が抑制される。
また、検知レバー１２をコムプレート６に連結しているピン１３が、検知レバー１２が第１ストッパ１６と当接した状態でのコムプレート６の回動により発生する荷重により折損するように構成されている。そこで、検知レバー１２が第１ストッパ１６に当接した後からマンコンベアの停止までのコムプレート６の回動トルクが検知レバー１２を介して第１ストッパ１６に伝達されない。これにより、第１ストッパ１６および検知スイッチ１５に過大な負荷がかからず、第１ストッパ１６および検知スイッチ１５の損傷の発生が抑制される。Moreover, since the stroke amount which operates the detection switch 15 is prescribed | regulated by the 1st stopper 16, generation | occurrence | production of the damage of the detection switch 15 resulting from the detection lever 12 pressing the detection switch 15 too much is suppressed.
Further, the pin 13 connecting the detection lever 12 to the comb plate 6 is configured to be broken by a load generated by the rotation of the comb plate 6 in a state where the detection lever 12 is in contact with the first stopper 16. ing. Therefore, the rotational torque of the comb plate 6 from when the detection lever 12 contacts the first stopper 16 to when the man conveyor stops is not transmitted to the first stopper 16 via the detection lever 12. Thereby, an excessive load is not applied to the first stopper 16 and the detection switch 15, and the occurrence of damage to the first stopper 16 and the detection switch 15 is suppressed.

ここで、ピン１３の折損荷重は、検知レバー１２の回動動作、および検知スイッチ１５の作動動作に支障のない程度の低荷重に設定されることが望ましい。   Here, it is desirable that the breaking load of the pin 13 is set to a low load that does not hinder the rotation operation of the detection lever 12 and the operation operation of the detection switch 15.

実施の形態２．
図６はこの発明の実施の形態２に係るマンコンベアの乗降口安全装置の作動後のマンコンベア停止時の状態を示す断面図である。Embodiment 2. FIG.
FIG. 6 is a cross-sectional view showing a state when the man conveyor stops after the operation of the entrance / exit safety device for man conveyor according to Embodiment 2 of the present invention.

図６において、検知レバー１２は、接着剤１８によりコムプレート６の幅方向の一側の側部に連結されている。接着剤１８の接着強度は、検知レバー１２の回動動作、および検知スイッチ１５の作動動作に支障のない程度の低強度に設定されている。
なお、他の構成は上記実施の形態１と同様に構成されている。In FIG. 6, the detection lever 12 is connected to a side portion on one side in the width direction of the comb plate 6 by an adhesive 18. The adhesive strength of the adhesive 18 is set to a low strength that does not hinder the rotation operation of the detection lever 12 and the operation operation of the detection switch 15.
Other configurations are the same as those in the first embodiment.

この実施の形態２では、マンコンベアの運転時に、踏段４上の異物１７がコム７と踏段４との間に挟み込まれると、コムプレート６が第１ばね１１を収縮させつつ、第１軸８を回動中心として回動し、コム７側が持ち上がる。検知レバー１２がコムプレート６の回動動作に連動して回動し、検知レバー１２の突出端が検知スイッチ１５を押圧する。そして、検知スイッチ１５が作動し、マンコンベアが停止される。   In the second embodiment, when the foreign matter 17 on the step 4 is sandwiched between the comb 7 and the step 4 during the operation of the man conveyor, the comb plate 6 contracts the first spring 11 while the first shaft 8 is contracted. And the comb 7 side is lifted. The detection lever 12 rotates in conjunction with the rotation operation of the comb plate 6, and the protruding end of the detection lever 12 presses the detection switch 15. Then, the detection switch 15 is activated and the man conveyor is stopped.

検知スイッチ１５が作動してからマンコンベアが停止されるまでのタイムラグの間に踏段４が移動し、異物１７がコム７と踏段４との間にさらに食い込む。そして、コムプレート６は、コム７と踏段４との間の異物１７の食い込み量の増大に連動して、コム７側がさらに持ち上がるように回動する。同時に、検知レバー１２が、コムプレート６の回動動作に連動して回動する。そして、検知レバー１２が第１ストッパ１６に当接し、検知スイッチ１５へのそれ以上の押圧が阻止される。コムプレート６がさらに回動すると、検知レバー１２の回動を阻止する荷重が、第１ストッパ１６により発生する。そこで、検知レバー１２に作用する荷重が、接着剤１８の接着強度を超えると、図６に示されるように、接着剤１８が剥離し、検知レバー１２がコムプレート６から外れ、検知レバー１２とコムプレート６との連結が解除される。すなわち、検知レバー１２の、コムプレート６の回動動作との連動が解除される。   The step 4 moves during the time lag from when the detection switch 15 is activated until the man conveyor is stopped, and the foreign matter 17 further bites between the comb 7 and the step 4. Then, the comb plate 6 rotates so that the comb 7 side is further lifted in conjunction with an increase in the amount of the foreign matter 17 between the comb 7 and the step 4. At the same time, the detection lever 12 rotates in conjunction with the rotation operation of the comb plate 6. And the detection lever 12 contact | abuts to the 1st stopper 16, and the further press to the detection switch 15 is blocked | prevented. When the comb plate 6 further rotates, a load that prevents the detection lever 12 from rotating is generated by the first stopper 16. Therefore, when the load acting on the detection lever 12 exceeds the adhesive strength of the adhesive 18, as shown in FIG. 6, the adhesive 18 peels off, the detection lever 12 comes off from the comb plate 6, and the detection lever 12 and The connection with the comb plate 6 is released. That is, the interlocking of the detection lever 12 with the turning operation of the comb plate 6 is released.

したがって、実施の形態２においても、上記実施の形態１と同様の効果が得られる。   Therefore, also in the second embodiment, the same effect as in the first embodiment can be obtained.

実施の形態３．
図７はこの発明の実施の形態３に係るマンコンベアの乗降口安全装置の通常状態を示す断面図、図８はこの発明の実施の形態３に係るマンコンベアの乗降口安全装置の作動後のマンコンベア停止時の状態を示す断面図である。Embodiment 3 FIG.
FIG. 7 is a sectional view showing a normal state of the entrance / exit safety device for a man conveyor according to Embodiment 3 of the present invention, and FIG. 8 is a view after the operation of the entrance / exit safety device for a man conveyor according to Embodiment 3 of the present invention. It is sectional drawing which shows the state at the time of a man conveyor stop.

図７において、検知レバー１２の踏段４と反対側の端部が、軸方向が第１軸８の軸方向と平行な第２軸２０により、コムプレート６の幅方向の一側の側部に連結されている。これにより、検知レバー１２は、コムプレート６から踏段４側に突出した状態で、第２軸２０を回動中心として回動可能にコムプレート６に取り付けられている。第２ばね２１が、検知レバー１２とコムプレート６との間に収縮状態で配設され、検知レバー１２の突出端側を持ち上げるように付勢している。第２ストッパ２２が、第２ばね２１により付勢されている検知レバー１２の踏段４と反対側の端部に当接し、第２ばね２１の付勢力を受けている。これにより、突出端側を持ち上げる方向の検知レバー１２の第２軸２０周りの回動が阻止され、検知レバー１２が通常位置に保持される。第２ばね２１は、検知レバー１２の回動動作、および検知スイッチ１５の作動動作に支障のない程度の小さなばね定数に設定される。
なお、他の構成は、上記実施の形態１と同様に構成されている。In FIG. 7, the end of the detection lever 12 opposite to the step 4 is positioned on one side of the comb plate 6 in the width direction by the second shaft 20 whose axial direction is parallel to the axial direction of the first shaft 8. It is connected. Thereby, the detection lever 12 is attached to the comb plate 6 so as to be rotatable about the second shaft 20 as a rotation center in a state of protruding from the comb plate 6 toward the step 4 side. The second spring 21 is disposed in a contracted state between the detection lever 12 and the comb plate 6 and urges to lift the protruding end side of the detection lever 12. The second stopper 22 is in contact with the end of the detection lever 12 biased by the second spring 21 on the side opposite to the step 4 and receives the biasing force of the second spring 21. Thereby, the rotation of the detection lever 12 around the second axis 20 in the direction of lifting the protruding end side is prevented, and the detection lever 12 is held at the normal position. The second spring 21 is set to a small spring constant that does not hinder the rotation operation of the detection lever 12 and the operation operation of the detection switch 15.
Other configurations are the same as those in the first embodiment.

実施の形態３では、マンコンベアの運転時に、踏段４上の異物１７がコム７と踏段４との間に挟み込まれると、コムプレート６は、第１ばね１１を収縮させつつ、第１軸８を回動中心として回動し、コム７側が持ち上がる。検知レバー１２がコムプレート６の回動動作に連動して回動し、検知レバー１２の突出端が検知スイッチ１５を押圧する。そして、検知スイッチ１５が作動し、マンコンベアが停止される。   In the third embodiment, when the foreign matter 17 on the step 4 is sandwiched between the comb 7 and the step 4 during operation of the man conveyor, the comb plate 6 causes the first shaft 8 to contract while the first spring 8 is contracted. And the comb 7 side is lifted. The detection lever 12 rotates in conjunction with the rotation operation of the comb plate 6, and the protruding end of the detection lever 12 presses the detection switch 15. Then, the detection switch 15 is activated and the man conveyor is stopped.

検知スイッチ１５が作動してからマンコンベアが停止されるまでのタイムラグの間に踏段４が移動し、異物１７がコム７と踏段４との間にさらに食い込む。そして、コムプレート６は、コム７と踏段４との間の異物１７の食い込み量の増大に連動して、コム７側がさらに持ち上がるように回動する。同時に、検知レバー１２が、コムプレート６の回動動作に連動して回動する。そして、検知レバー１２が第１ストッパ１６に当接し、検知スイッチ１５へのそれ以上の押圧が阻止される。コムプレート６がさらに回動すると、検知レバー１２の回動を阻止する荷重が、第１ストッパ１６により発生する。そこで、コムプレート６は、図８に示されるように、第２ばね２１を収縮させつつ、第１軸８を回動中心として、時計回りに回動する。一方、検知レバー１２は、第２ばね２１を収縮させつつ、第２軸２０を回動中心として、反時計回りに回動する。このように、検知レバー１２とコムプレート６との連結が解除され、検知レバー１２は、コムプレート６の回動方向と逆方向に回動する。これにより、検知レバー１２とコムプレート６との連結が解除され、コムプレート６の回動トルクが第１ストッパ１６に伝達されなくなる。   The step 4 moves during the time lag from when the detection switch 15 is activated until the man conveyor is stopped, and the foreign matter 17 further bites between the comb 7 and the step 4. Then, the comb plate 6 rotates so that the comb 7 side is further lifted in conjunction with an increase in the amount of the foreign matter 17 between the comb 7 and the step 4. At the same time, the detection lever 12 rotates in conjunction with the rotation operation of the comb plate 6. And the detection lever 12 contact | abuts to the 1st stopper 16, and the further press to the detection switch 15 is blocked | prevented. When the comb plate 6 further rotates, a load that prevents the detection lever 12 from rotating is generated by the first stopper 16. Therefore, as shown in FIG. 8, the comb plate 6 rotates clockwise around the first shaft 8 while contracting the second spring 21. On the other hand, the detection lever 12 rotates counterclockwise around the second shaft 20 while contracting the second spring 21. Thus, the connection between the detection lever 12 and the comb plate 6 is released, and the detection lever 12 rotates in the direction opposite to the rotation direction of the comb plate 6. Thereby, the connection between the detection lever 12 and the comb plate 6 is released, and the rotational torque of the comb plate 6 is not transmitted to the first stopper 16.

したがって、実施の形態３においても、上記実施の形態１と同様の効果が得られる。   Therefore, also in Embodiment 3, the same effect as in Embodiment 1 can be obtained.

なお、上記各実施の形態では、乗降口安全装置がコムプレートの幅方向の一側の側部に配設されているが、乗降口安全装置はムプレートの幅方向の両側の側部に配設されてもよい。
また、上記各実施の形態では、コムプレートの踏段と反対側の端部をフレームに連結する第１軸を回動中心として、コムプレートの踏段側が持ち上がるにようにフレームに取り付けられているが、コムプレートの踏段と反対側の端部の下面を支持する支持ボルトの先端を回動中心として、コムプレートの踏段側が持ち上がるにようにフレームに取り付けられてもよい。In each of the above embodiments, the entrance / exit safety device is disposed on one side of the comb plate in the width direction, but the entrance / exit safety device is disposed on both sides in the width direction of the mu plate. May be.
Further, in each of the above embodiments, the comb plate is attached to the frame so that the step side of the comb plate is lifted around the first axis that connects the end of the comb plate opposite to the step to the frame as a center of rotation. The comb plate may be attached to the frame so that the step side of the comb plate is lifted around the tip end of the support bolt that supports the lower surface of the end portion opposite to the step of the comb plate.
