Description

本発明は、上かごと下かごとの間の間隔を調整するかご間調整機構を有するダブルデッキエレベーターに関する。 The present invention relates to a double-deck elevator having a car-to-car adjustment mechanism that adjusts an interval between an upper car and a lower car.

近年、ビルの高層、大容量化が進み、ビルに設置されるエレベーターも多くの乗客を一度に運ぶことが必要となる。しかし、エレベーターの設置台数を増やすとビルのフロア面積が減ってしまうため、ワンシャフトで多人数を輸送できるダブルデッキエレベーターが、特にメインフロアから高層階に直通するシャトルエレベーターなどに適用されている。そして、メインフロアと高層階では、一般的に階間の高さが異なることが多く、階間を調整できるようなダブルデッキエレベーターが提案されている。   In recent years, buildings have become higher-rise and have larger capacities, and elevators installed in buildings need to carry many passengers at once. However, if the number of installed elevators is increased, the floor area of the building is reduced, so a double deck elevator that can transport a large number of people with a single shaft is applied particularly to a shuttle elevator that directly connects from the main floor to a higher floor. And, the main floor and the higher floors generally have different heights between the floors, and a double deck elevator that can adjust the floors has been proposed.

階間調整可能なダブルデッキエレベーターの従来技術としては、主枠の中に、上下かごが設置され、これにロープを巻き掛けてかご内に設けられたかご位置調整用駆動装置を動作させることにより上下のかごの位置を相反方向に移動させ、階間調整を可能にしたものである。（例えば、特許文献１参照）。 As a conventional technology of the double deck elevator that can adjust the floor, the upper and lower cars are installed in the main frame, and the car position adjustment drive device provided in the car is operated by winding the rope around this The upper and lower car positions are moved in the opposite direction to enable adjustment of the floor. (For example, refer to Patent Document 1).

また、かごが所定の階床に到着して停止した後に、乗客の乗降により生じたかご床と乗場との間の床ずれを補正するために、かご内の負荷率の変化量を演算し、その値に基づいて上下かごの位置をかご間隔調整装置で調整する方法で上下かご同時に床合わせ動作を行うダブルデッキエレベーターが提案されている（例えば、特許文献２参照）。   In addition, after the car arrives at the predetermined floor and stops, the amount of change in the load factor in the car is calculated in order to correct the floor slip between the car floor and the landing caused by passengers getting on and off. There has been proposed a double-deck elevator that performs floor-to-top car simultaneous floor-to-floor operation by adjusting the position of the upper and lower cars with a car interval adjusting device based on the value (see, for example, Patent Document 2).

特開２００７−３３１８７１号公報（００２４欄、００２５欄及び図１）JP 2007-331871 (columns 0024 and 0025 and FIG. 1) 特開２００２−３３８１５４号公報（００２７欄〜００２９欄及び図２）JP 2002-338154 A (columns 0027 to 0029 and FIG. 2)

しかしながら、特許文献１に記載の階間調整可能なダブルデッキエレベーターは上下かごが連動して動くため、着床レベルずれを起こしやすく、着床時や、着床後に乗客の乗降があった場合に段差が発生する可能性が高くなるといった問題がある。 However, the double-deck elevator that can adjust the floor described in Patent Document 1 moves up and down in conjunction with each other, so that it is easy for the landing level to shift, and when landing or when passengers get on and off after landing. There is a problem that there is a high possibility that a step is generated.

また、特許文献２については、階床に到着した時の乗客の乗降により生じた上下かごの床ずれレベルは逆方向に略等しいことを前提にかご間隔調整装置で上下かご同時に床合わせ動作を行っているが、実際はかご床下に設けられた防振ゴムの影響で上かごと下かごが同方向に床ずれを起こしたり上下かごの床ずれレベルが異なることがあり、上下かごが連動して動作するようなシステムでは、上下かごの床レベルをゼロにすることは難しいといった問題がある。   In addition, with respect to Patent Document 2, the floor gap level of the upper and lower cars caused by passengers getting on and off when arriving at the floor is approximately equal in the opposite direction, and the floor interval operation is performed simultaneously with the upper and lower cars with the car interval adjusting device. However, in actuality, the upper and lower cars may cause floor slips in the same direction due to the anti-vibration rubber installed under the car floor, and the floor slip levels of the upper and lower cars may be different. In the system, there is a problem that it is difficult to make the floor level of the upper and lower cars zero.

この発明は、上下かごそれぞれの床ずれのレベルの状態により、主枠、上下かご又はその両方のいずれを動かすかを選択することで、上下カゴの床ずれレベルを調整して段差を小さくすることができるダブルデッキエレベーターを提供することを目的とする。   According to the present invention, it is possible to adjust the floor slip level of the upper and lower cages to reduce the level difference by selecting which of the main frame, the upper and lower cages or both of them is moved according to the level of the floor slip of each of the upper and lower cars. The purpose is to provide a double deck elevator.

この発明に係るダブルデッキエレベーターでは、建物の昇降路を昇降する主枠を駆動する主駆動装置と、主枠の内部に配設した上下２段のかごと、主枠の上部に設けられるとともに、上下２段のかごをそれぞれ主枠に対して吊り下げるロープが巻きかけられる位置調整用駆動シーブを有し、位置調整用駆動シーブを回転させかごを主枠内で互いに相反する上下方向へ移動させかごの間隔を変化させるかご位置調整用駆動装置と、かごのそれぞれに設けられたかご検出センサにより検出されたかご出入口の床ずれレベルの少なくとも一方が、予め記憶手段に記憶され床ずれレベルの補正を行うか否かの基準となる床ずれレベルの閾値以上であるかどうかを比較して判定する判定手段と、判定手段によりかご出入口の床ずれレベルの少なくとも一方が閾値以上であると判定された場合には、床ずれレベルの補正を行う複数の条件に上下２段のかごの床ずれレベルをそれぞれ順次当てはめて演算する演算手段と、演算手段の演算結果により複数の条件のうち所定の条件が成立した場合には、所定の条件に対応して主駆動装置、かご位置調整用駆動装置、又は主駆動装置とかご位置調整用駆動装置の両方のいずれを駆動するかを選択する選択手段とを備えたものである。   In the double deck elevator according to the present invention, the main drive device for driving the main frame that moves up and down the hoistway of the building, the upper and lower two-stage cages arranged inside the main frame, the upper frame and the upper frame are provided. There is a drive sheave for position adjustment around which a rope that suspends the two-stage car from the main frame is wound, and the car is moved in the vertical direction opposite to each other in the main frame by rotating the position adjustment drive sheave. Whether at least one of the car position adjustment driving device that changes the interval of the car and the car slippage level detected by the car detection sensor provided in each car is previously stored in the storage means and the floor slip level is corrected. A judgment means for comparing whether or not the floor slip level is equal to or higher than a threshold value of a floor slip level that is a criterion for the determination, and at least one of the floor slip levels at the car doorway by the judgment means. Is determined to be equal to or greater than the threshold value, the calculation means for sequentially applying the floor slip levels of the upper and lower two-stage cars to the plurality of conditions for correcting the floor slip level, respectively, When a predetermined condition among the conditions is satisfied, which of the main driving device, the car position adjusting driving device, or both the main driving device and the car position adjusting driving device is driven corresponding to the predetermined condition Selection means for selecting.

この発明に係るダブルデッキエレベーターによれば、上下かごそれぞれの床ずれのレベルの状態により、主枠、上下かご又はその両方のいずれを動かすかを選択することで、上下カゴの床ずれレベルを調整して段差を小さくすることができるという効果を有する。 According to the double deck elevator according to the present invention, the floor slip level of the upper and lower cages is adjusted by selecting which of the main frame, the upper and lower cages or both of them is moved according to the level of the floor slip of each of the upper and lower cages. The step can be reduced.

実施の形態１．
以下、この発明を実施するための形態について、図面を参照して説明する。Embodiment 1 FIG.
Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

本実施の形態１におけるダブルデッキエレベーターについて説明する。先ず、ダブルデッキエレベーターの構成について説明する。   The double deck elevator in the first embodiment will be described. First, the configuration of the double deck elevator will be described.

図１はこの発明の実施の形態１におけるダブルデッキエレベーターを示す概略構成図である。
図１において、エレベーターの昇降路の頂部にはエレベーターのかご装置５０を駆動するための主駆動装置２０が主駆動シーブ２１と連結されて設けられている。また、主駆動装置２０の付近にはかご装置５０と釣合おもり２５が接触しないためのそらせ車２２が配置されている。主駆動シーブ２１及びそらせ車２２には、複数本のロープを束ねてなる主索２３が巻き掛けられており、主索２３の一端部には、かご装置５０が吊り下げられているとともに、主索２３の他端部には釣合おもり２５が吊り下げられている。また、かご装置５０及び釣合おもり２５は、主索２３により１：１ローピング方式で吊り下げられており、主駆動装置２０の駆動力により昇降路内を上下方向に昇降する。ここで、１：１ローピング方式とは、主索２３の速度とかご装置５０の速度の比が１：１となるようなロープ方式のことをいう。1 is a schematic configuration diagram showing a double deck elevator according to Embodiment 1 of the present invention.
In FIG. 1, a main drive device 20 for driving an elevator car device 50 is connected to a main drive sheave 21 at the top of an elevator hoistway. Further, in the vicinity of the main drive device 20, a deflection wheel 22 is arranged so that the car device 50 and the counterweight 25 do not come into contact with each other. A main rope 23 formed by bundling a plurality of ropes is wound around the main drive sheave 21 and the deflecting wheel 22, and a car device 50 is suspended from one end of the main rope 23. A counterweight 25 is suspended from the other end of the cable 23. Further, the car device 50 and the counterweight 25 are suspended by the main rope 23 in a 1: 1 roping method, and are moved up and down in the hoistway by the driving force of the main driving device 20. Here, the 1: 1 roping method refers to a rope method in which the ratio of the speed of the main rope 23 and the speed of the car device 50 is 1: 1.

かご装置５０の主枠２４は、一対の縦枠１、上梁２、中間梁４、下梁３、一対の上かごガイドレール（図示略）、及び一対の下かごガイドレール（図示略）を有している。上梁２は、縦梁１の上端部間に水平に固定されている。また、中間梁４は一対の縦梁１の中間部間に水平に固定されている。また、下梁３は縦梁１の下端部間に水平に固定されている。そして、上かごガイドレールは上かご２６の主枠２に対する相対的な昇降を案内するためのものであり、下かごガイドレールは下かご２８の主枠２に対する相対的な昇降を案内するためのものであり、共に主枠２４の内側に縦枠１と平行に固定されている。   The main frame 24 of the car device 50 includes a pair of vertical frames 1, an upper beam 2, an intermediate beam 4, a lower beam 3, a pair of upper car guide rails (not shown), and a pair of lower car guide rails (not shown). Have. The upper beam 2 is fixed horizontally between the upper ends of the vertical beams 1. The intermediate beam 4 is horizontally fixed between the intermediate portions of the pair of vertical beams 1. The lower beam 3 is horizontally fixed between the lower ends of the vertical beams 1. The upper car guide rail is used to guide the relative raising / lowering of the upper car 26 relative to the main frame 2, and the lower car guide rail is used to guide the relative raising / lowering of the lower car 28 relative to the main frame 2. Both are fixed inside the main frame 24 in parallel with the vertical frame 1.

主枠２４は、上下の領域に分割されており、上方の領域つまり上枠２と中間梁４との間には上かご２６が配設されており、下方の領域つまり中間梁４と下梁３との間には下かご２８が配設されている。上かご２６は、上かごガイドレールに沿って上下移動可能になっており、下かご２８は、下かごガイドレールに沿って上下移動可能になっている。   The main frame 24 is divided into upper and lower regions, and an upper car 26 is disposed between the upper region, that is, the upper frame 2 and the intermediate beam 4, and the lower region, that is, the intermediate beam 4 and the lower beam. A lower car 28 is disposed between the upper car 3 and the car 3. The upper car 26 can move up and down along the upper car guide rail, and the lower car 28 can move up and down along the lower car guide rail.

上かご２６及び下かご２８には、それぞれのかごを吊るための吊り車２７、２９を下部に有しており、吊車には上下２段のかごをそれぞれ前記主枠に対して吊り下げる複数本のロープ３０、３３が巻き付けられている。上かごのロープ３０の一端は主枠上部の上梁２に設けられた固定部材３１で固定されており、他端はかご位置調整用駆動装置５の位置調整用駆動シーブ３２に巻きかけられている。同じように下かごのロープ３３の一端は主枠中間部に設けられた固定部材３４で固定されており、他端はかご位置調整用駆動装置５の位置調整用駆動シーブ３２に巻付けられている。ここで、かご位置調整用駆動装置５は、主枠２４の上部であって上梁２の下部に取り付けられており、上かご２６及び下かご２８を主枠２４内で互いに相反する上下方向へ移動させることにより両者の間隔を調整するものである。また、かご位置調整用駆動装置５は位置調整用駆動シーブ３２を有しており、位置調整用駆動シーブ３２の回転軸が上かご２６の幅方向と平行になるように配置されている。   The upper car 26 and the lower car 28 have suspension cars 27 and 29 for suspending the respective cars at the lower part, and the suspended cars have a plurality of upper and lower cars suspended from the main frame. Ropes 30 and 33 are wound. One end of the rope 30 of the upper car is fixed by a fixing member 31 provided on the upper beam 2 at the upper part of the main frame, and the other end is wound around the position adjusting drive sheave 32 of the car position adjusting driving device 5. Yes. Similarly, one end of the lower car rope 33 is fixed by a fixing member 34 provided in the middle portion of the main frame, and the other end is wound around the position adjusting drive sheave 32 of the car position adjusting driving device 5. Yes. Here, the car position adjusting drive device 5 is attached to the upper part of the main frame 24 and to the lower part of the upper beam 2, and the upper car 26 and the lower car 28 are moved in the vertical direction opposite to each other in the main frame 24. The distance between the two is adjusted by the movement. Further, the car position adjusting drive device 5 has a position adjusting drive sheave 32, and the rotation shaft of the position adjusting drive sheave 32 is arranged so as to be parallel to the width direction of the upper car 26.

上かごロープ３０と下かごロープ３３は一本で繋がったロープであり、上かごのロープ３０の他端と下かごのロープ３３の他端とが繋がって位置調整用駆動シーブ３２に例えば約一周半巻付けられている。また、上下のかごは２：１ローピング方式により吊り下げられており、かご位置調整用駆動装置５を動作させることにより連動して上下かごが動作する。２：１ローピング方式とは、主索２３の速度とかご装置５０の速度の比が２：１となるようなロープ方式のことをいう。なお、上かごのロープ３０と下かごのロープ３３とを別のロープで構成しても良く、その場合に上かごのロープ３０と下かごのロープ３３の位置調整用駆動シーブ３２に巻く方向を時計回りと反時計回りにして、他端をそれぞれ中間梁４の上部に固定すればよい。   The upper car rope 30 and the lower car rope 33 are connected by a single rope, and the other end of the upper car rope 30 and the other end of the lower car rope 33 are connected to the drive sheave 32 for position adjustment, for example, about one turn. Half-wrapped. Further, the upper and lower cars are suspended by a 2: 1 roping method, and the upper and lower cars operate in conjunction with each other by operating the car position adjusting driving device 5. The 2: 1 roping method refers to a rope method in which the ratio of the speed of the main rope 23 and the speed of the car device 50 is 2: 1. Note that the upper car rope 30 and the lower car rope 33 may be composed of different ropes, and in this case, the direction of winding around the position adjusting drive sheave 32 of the upper car rope 30 and the lower car rope 33 is determined. What is necessary is just to fix an other end to the upper part of the intermediate beam 4, respectively clockwise and counterclockwise.

３５は上かご用の緩衝器、３６は下かご用の緩衝器であり。かごの衝撃を吸収するためのものである。また、上下かご３６、３８には、着床時あるいは着床後のかご出入口の床ずれを検知するかご検出センサを備えている。３７は上かごに設置された上かご検出センサであり、昇降路に設置されたプレート３８との相対位置を検知し床ずれレベル４１を検出することができる。同じく下かごにも下かご検出センサ３９であり、昇降路に設置されたプレート４０との位置を検知し下かごの出入口の床ずれレベル４２を検出することができる。また、主枠２４の上部には、上かご検出センサ３７及び下かご検出センサ３９で検出された床ずれレベル４１及び床ずれレベル４２に基づいて主駆動装置２０、かご位置調整用駆動装置５、あるいはその両方に対して床合せ運転の指令を送る床合せ制御装置１２が設けられている。また、６は連続した上下階の階間距離を指す。 35 is a shock absorber for the upper car, and 36 is a shock absorber for the lower car. This is to absorb the impact of the car. In addition, the upper and lower cars 36 and 38 are provided with car detection sensors for detecting a floor slip at the car doorway when landing or after landing. Reference numeral 37 denotes an upper car detection sensor installed in the upper car, which can detect the relative position with respect to the plate 38 installed in the hoistway to detect the floor slip level 41. Similarly, a lower car detection sensor 39 is also provided for the lower car, and can detect the floor slip level 42 at the entrance / exit of the lower car by detecting the position of the plate 40 installed in the hoistway. Further, on the upper part of the main frame 24, the main driving device 20, the car position adjusting driving device 5, or the same based on the floor displacement level 41 and the floor displacement level 42 detected by the upper car detection sensor 37 and the lower car detection sensor 39. A floor alignment control device 12 is provided that sends a floor alignment operation command to both. 6 indicates the distance between the upper and lower continuous floors.

次に、動作について説明する。かご装置５０（主枠２４）及び釣合おもり２５は、主駆動装置２０の駆動力により、昇降路内を昇降する。上かご２６及び下かご２８は、上下に隣接した乗場階に同時に着床されるが、建物の階床間隔は必ずしも一定ではなく、階によって異なっていることがあるため、このような場合は、かご位置調整用駆動装置５によって上かご２６及び下かご２８が主枠２４に対して相対的に昇降し、両者の間隔が階床間隔に応じて調整される。即ち、上かご２６が下降すると下かご２８が上昇し、両者の間隔は縮小する。また、上かご２６が上昇すると下かご２８が下降し、両者の間隔は拡大する。すなわち、かご位置調整用駆動装置５による上下かごの移動量の絶対値は略等しくなる。通常移動する階床の幅はあらかじめ記憶されており、到着する前に上下かごの間隔を調整してから、主枠２４がその階床に移動する。 Next, the operation will be described. The car device 50 (main frame 24) and the counterweight 25 are moved up and down in the hoistway by the driving force of the main drive device 20. The upper car 26 and the lower car 28 are simultaneously landed on the landing floors adjacent to each other in the upper and lower sides, but the floor space of the building is not necessarily constant and may vary depending on the floor. The upper car 26 and the lower car 28 are moved up and down relatively with respect to the main frame 24 by the car position adjusting driving device 5, and the distance between them is adjusted according to the floor space. That is, when the upper car 26 is lowered, the lower car 28 is raised, and the distance between the two is reduced. When the upper car 26 is raised, the lower car 28 is lowered and the distance between the two is increased. In other words, the absolute values of the movement amounts of the upper and lower cars by the car position adjusting drive device 5 are substantially equal. The width of the floor that normally moves is stored in advance, and the main frame 24 moves to that floor after adjusting the distance between the upper and lower cars before arrival.

図２は、この発明の実施の形態１における床合せ制御装置の機能を示す機能ブロック図である。
図２において、上かご検出センサ３７及び下かご検出センサ３９は、上下かご３６、３８にそれぞれ設けられた床ずれレベルを検出する検出センサである。昇降路に設置されたプレート３８の位置と上かご検出センサ３７の位置が一致したときに床ずれレベルが０となるようプレート３８の位置が定められている。同様に、プレート４０の位置と下かご検出センサ３９の位置が一致したときに床ずれレベルが０となるようプレート４０の位置が定められている。なお、かごが基準位置よりも上方にずれている場合を正、下方にずれている場合を負と表現するものとする。FIG. 2 is a functional block diagram showing functions of the floor matching control apparatus according to Embodiment 1 of the present invention.
In FIG. 2, an upper car detection sensor 37 and a lower car detection sensor 39 are detection sensors that detect floor slip levels provided in the upper and lower cars 36 and 38, respectively. The position of the plate 38 is determined so that the floor displacement level becomes 0 when the position of the plate 38 installed in the hoistway and the position of the upper car detection sensor 37 coincide. Similarly, the position of the plate 40 is determined so that the floor displacement level becomes 0 when the position of the plate 40 and the position of the lower car detection sensor 39 coincide. Note that the case where the car is shifted upward from the reference position is expressed as positive, and the case where the car is shifted downward is expressed as negative.

主枠２４の上部に設けられた床合せ制御装置１２は上下かご２６、２８と乗場との間に生じた段差を閾値以内あるいは０となるよう上下かご２６、２８の調整を行い床合せ、つまり床ずれレベルの補正を行うものである。そして、床合せ制御装置１２は、床ずれレベル認識・判定手段７、条件式演算手段８、記憶手段９、床合せ運転選択・演算手段１０、及び床合せ運転指令手段１１から構成される。   The floor alignment control device 12 provided at the upper part of the main frame 24 adjusts the upper and lower cars 26 and 28 so that the level difference generated between the upper and lower cars 26 and 28 and the landing is within the threshold value or 0, that is, the floor alignment is performed. This corrects the bed slip level. The floor alignment control device 12 includes a floor displacement level recognition / determination unit 7, a conditional expression calculation unit 8, a storage unit 9, a floor alignment operation selection / calculation unit 10, and a floor alignment operation command unit 11.

床ずれレベル認識・判定手段７（判定手段）は、上かご検出センサ３７及び下かご検出センサ３９で検出した床ずれレベル４１、４２を認識し、上かご２６もしくは下かご２８の床ずれレベルが床合せを行うか否かの基準となる前記床ずれレベルの閾値以上であるかを判定するものである。また、記憶手段９は、床ずれレベル認識・判定手段７で上かご２６もしくは下かご２８の床ずれレベルが閾値以上であるかを判定する際に比較する閾値を予め記憶し、また、主駆動装置２０、かご位置調整用駆動装置５、あるいはその両方のいずれを駆動するかを判断するための条件式、及び床合せ量を決める数式を記憶するものである。条件式演算手段８（演算手段）は、床ずれレベル認識・判定手段７で少なくとも上下かご２６、２８のいずれかが閾値以上の床ずれレベルである場合の上下かご２６、２８の床ずれレベルを記憶手段９に記憶された複数の条件式に順次当てはめて演算するものである。床合せ運転選択・演算手段１０（選択手段）は、条件式演算手段８の演算結果により複数の条件式のうち所定の条件が成立した場合に、その所定の条件に対応して主駆動装置２０、かご位置調整用駆動装置５、あるいはその両方のいずれを駆動するかを選択するとともに、記憶手段９に記憶された床合せ量を決める数式に基づいて主駆動装置２０、かご位置調整用駆動装置５、あるいはその両方のいずれを何ｍｍ移動させるかを演算する。床合せ運転指令手段１１は、床合せ運転選択・演算手段１０の判定・演算結果に従って主駆動装置２０、かご位置調整用駆動装置５、あるいはその両方に駆動の指令を出すものである。   The floor slip level recognition / determination means 7 (determination means) recognizes the floor slip levels 41 and 42 detected by the upper car detection sensor 37 and the lower car detection sensor 39, and the floor slip level of the upper car 26 or the lower car 28 matches the floor. It is determined whether it is equal to or more than a threshold value of the floor slip level that is a criterion for determining whether or not to perform. The storage means 9 stores in advance a threshold value to be compared when the floor slip level recognition / determination means 7 determines whether the floor slip level of the upper car 26 or the lower car 28 is equal to or higher than the threshold value. The car position adjustment driving device 5 or both of them is stored as a conditional expression and a mathematical expression for determining the floor alignment amount. The conditional expression calculation means 8 (calculation means) stores the floor shift levels of the upper and lower cars 26 and 28 when at least one of the upper and lower cars 26 and 28 is the floor shift level equal to or higher than the threshold value in the floor shift level recognition / determination means 7. The calculation is performed by sequentially applying to a plurality of conditional expressions stored in. The floor alignment operation selection / calculation means 10 (selection means), when a predetermined condition among a plurality of conditional expressions is satisfied according to the calculation result of the conditional expression calculation means 8, corresponds to the predetermined condition. The car position adjusting driving device 5 or both of them is selected, and the main driving device 20 and the car position adjusting driving device are selected on the basis of the mathematical formula for determining the floor alignment amount stored in the storage means 9. 5 or how many mm of both are moved. The floor alignment operation command means 11 outputs a drive command to the main drive device 20, the car position adjustment drive device 5 or both according to the determination / calculation result of the floor alignment operation selection / calculation means 10.

上記の実施の形態１のダブルデッキエレベーターにおける着床後の動作について説明する。
図３は、この発明の実施の形態１におけるダブルデッキエレベーターの動作を示すフローチャートである。
上述したとおり、エレベーターのかご装置５０が乗場到着する前に上下かごの間隔を調整してから、主枠２４がその階床に移動する。しかしながら、かご装置５０が停止し、乗客が乗り降りすることにより上かご２６と乗場あるいは下かご２８と乗場との間に床ずれが発生する。このとき、上かご２６と下かごに生じる床ずれは、乗客の負荷による上下かごの床下に設けられたかごの揺れを防止するための防振ゴムの撓みの影響や、乗客の負荷による上下かごロープ３０、３３の一時的な伸びの影響等により、同方向にも逆方向にも生じる可能性がある。The operation after landing in the double deck elevator according to the first embodiment will be described.
FIG. 3 is a flowchart showing the operation of the double deck elevator according to Embodiment 1 of the present invention.
As described above, the main frame 24 moves to the floor after adjusting the distance between the upper and lower cars before the elevator car device 50 arrives at the landing. However, when the car device 50 stops and passengers get on and off, a floor slip occurs between the upper car 26 and the landing or the lower car 28 and the landing. At this time, the floor slip generated in the upper car 26 and the lower car is affected by the deflection of the anti-vibration rubber for preventing the car from being shaken under the floor of the upper and lower cars due to the passenger's load, and the upper and lower car ropes caused by the passenger's load. There is a possibility that it may occur in the same direction or in the opposite direction due to the effect of temporary elongation of 30,33.

図１〜図３において、上かご２６の着床後に乗客が乗降した際に生じた出入口の床ずれレベル４１を上かご検出センサ３７が検出する。同様に下かご２８の着床後に乗客が乗降した際に生じた下かごの出入口の床ずれレベル４２を下かご検出センサ３９が検出する。そして、床ずれレベル認識・判定手段７は、上かご検出センサ３７及び下かご検出センサ３９から入力された床ずれレベル４１、４２を認識する。また、床ずれレベル認識・判定手段７は、記憶手段９に記憶された閾値と床ずれレベル４１、４２を比較して、上かご２６もしくは下かご２８の少なくとも一方が閾値以上であるかを判定する（Ｓ１０１）。閾値以上であった場合には、Ｓ１０２以降に進み、記憶手段９に記憶された複数の条件式に上下２段のかごの床ずれレベルを順次当てはめて演算する。一方、閾値未満であれば以降の処理を行わない。   In FIG. 1 to FIG. 3, the upper car detection sensor 37 detects a floor shift level 41 at the doorway that occurs when a passenger gets on and off after the upper car 26 has landed. Similarly, the lower car detection sensor 39 detects a floor shift level 42 at the entrance / exit of the lower car that occurs when a passenger gets on and off after the lower car 28 has landed. The floor slip level recognition / determination means 7 recognizes the floor slip levels 41 and 42 input from the upper car detection sensor 37 and the lower car detection sensor 39. Further, the floor slip level recognition / determination means 7 compares the threshold stored in the storage means 9 with the floor slip levels 41 and 42 and determines whether at least one of the upper car 26 or the lower car 28 is equal to or greater than the threshold ( S101). If it is equal to or greater than the threshold value, the process proceeds to S102 and subsequent steps, and the floor slip levels of the upper and lower two-stage cars are sequentially applied to a plurality of conditional expressions stored in the storage means 9 for calculation. On the other hand, if it is less than the threshold value, the subsequent processing is not performed.

Ｓ１０２では、条件式演算手段８が、記憶手段９に記憶された床ずれの条件式｜上かご床ずれレベル４１−下かご床ずれレベル４２｜／２≦閾値に床ずれレベル４１、４２を当てはめて条件式が成立するかを判断する。そして、条件式が成立した場合にはＳ１０６に進む。逆に条件式が成立しなかった場合にはＳ１０３に進む。   In S102, the conditional expression calculation unit 8 applies the floor shift levels 41 and 42 to the floor slip condition expression | upper car floor shift level 41−lower car floor shift level 42 | / 2 ≦ threshold value stored in the storage unit 9 to obtain the conditional expression. Judgment is made. If the conditional expression is satisfied, the process proceeds to S106. Conversely, if the conditional expression is not satisfied, the process proceeds to S103.

Ｓ１０６では、条件式演算手段８が判断した条件式の成立に対応して主駆動装置２０（主枠２４）を駆動するよう選択する。また、その駆動量である床合せレベルとしては、記憶手段９に記憶された主枠床合わせレベル＝−（上かご床ずれレベル４１＋下かご床ずれレベル４２）／２という数式を用いて上かご床ずれレベル４１及び下かご床ずれレベル４２を当てはめて床合わせレベルを演算する。そして、演算された床合わせレベル分主駆動装置２０を作動させるよう床合せ運転指令手段１１が主駆動装置２０に駆動の指令を出し、その指令に従って主駆動装置２０による床合せを行う。 In S106, selection is made to drive the main drive unit 20 (main frame 24) in response to the establishment of the conditional expression determined by the conditional expression calculation means 8. Further, as the floor alignment level, which is the driving amount, the upper car floor displacement level is calculated using the following equation: main frame floor alignment level stored in the storage unit 9 = − (upper car floor displacement level 41 + lower car floor displacement level 42) / 2. 41 and the lower car floor slip level 42 are applied to calculate the floor alignment level. Then, the floor alignment operation command means 11 issues a drive command to the main drive device 20 to operate the main drive device 20 for the calculated floor alignment level, and the main drive device 20 performs floor alignment according to the command.

ここで、具体的な例を図４で説明する。図４は、この発明の実施の形態１における主駆動装置で主枠を動作させて床合わせを行う場合の一例を示す説明図である。まず、記憶手段９に記憶されている床合せ実施要否の閾値を例えば５ｍｍとする。その場合は、上かご床ずれレベル４１もしくは下かご床ずれレベル４２が閾値５ｍｍ以上、−５ｍｍ以下の時、床合せを実施する。｜上かご床ずれレベル４１−下かご床ずれレベル４２｜／２≦閾値（５ｍｍ）の場合は主枠を移動させる。ここで、主枠床合わせレベル＝−（上かご床ずれレベル４１＋下かご床ずれレベル４２）／２の数式に上かご床ずれレベル８ｍｍ及び下かご床ずれレベル４ｍｍを当てはめると−６ｍｍとなり、主枠（主駆動装置２０）を−６ｍｍ移動させる。それにより上かごの床ずれ４１は２ｍｍ、下かご床ずれは−２ｍｍとなり上下出入口とも閾値５ｍｍ以内となる。同じく、上かご床ずれが３ｍｍで下かご床ずれ４２が７ｍｍの場合、主枠を５ｍｍ移動させることにより、上かごの床ずれ４１は−２ｍｍ、下かご床ずれは２ｍｍとなり上下出入口とも閾値以内となる。このように、主枠２４の移動のみで、上下かごを閾値内に床合せすることが可能である。 Here, a specific example will be described with reference to FIG. FIG. 4 is an explanatory diagram showing an example in which floor alignment is performed by operating the main frame in the main drive apparatus according to Embodiment 1 of the present invention. First, the threshold for necessity of floor alignment stored in the storage means 9 is set to 5 mm, for example. In this case, when the upper car floor slip level 41 or the lower car floor slip level 42 is not less than the threshold value 5 mm and not more than −5 mm, floor matching is performed. When the upper car floor slip level 41-the lower car floor slip level 42 | / 2 ≦ threshold (5 mm), the main frame is moved. Here, when the upper car floor displacement level 8 mm and the lower car floor displacement level 4 mm are applied to the formula of main frame floor alignment level = − (upper car floor displacement level 41 + lower car floor displacement level 42) / 2, the result is −6 mm. The device 20) is moved -6 mm. As a result, the floor deviation 41 of the upper car is 2 mm, the floor deviation of the lower car is -2 mm, and the upper and lower doorways are within the threshold value of 5 mm. Similarly, when the upper car floor slip is 3 mm and the lower car floor slip 42 is 7 mm, the upper car floor slip 41 is -2 mm and the lower car floor slip is 2 mm by moving the main frame by 5 mm. In this way, it is possible to floor the upper and lower cars within the threshold only by moving the main frame 24.

Ｓ１０３に進むと、次に条件式演算手段８は、記憶手段９に記憶された床ずれの条件式｜上かご床ずれレベル４２＋下かご床ずれレベル４４｜／２≦閾値に床ずれレベル４１、４２を当てはめて条件式が成立するかを判断する。そして、条件式が成立した場合にはＳ１０５に進む。逆に条件式が成立しなかった場合にはＳ１０４に進む。 In S103, the conditional expression calculation means 8 applies the floor slip levels 41 and 42 to the floor slip condition expression | upper car floor slip level 42 + lower car floor slip level 44 | / 2 ≦ threshold value stored in the storage means 9. It is determined whether the conditional expression is satisfied. If the conditional expression is satisfied, the process proceeds to S105. Conversely, if the conditional expression is not satisfied, the process proceeds to S104.

Ｓ１０５では、条件式演算手段８が判断した条件式の成立に基づいて位置調整用駆動装置５（上下かご２６、２８）を駆動するよう選択する。また、その駆動量である床合せレベルとしては、記憶手段９に記憶された上かご床合わせレベル＝（下かご床ずれレベル４２−上かご床ずれレベル４１）／２若しくは下かご床合わせレベル＝（上かご床ずれレベル４１−下かご床ずれレベル４２）／２という数式を用いて上かご床ずれレベル４１及び下かご床ずれレベル４２を当てはめて床合わせレベルを演算する。そして、演算された床合わせレベル分位置調整用駆動装置５を作動させるよう床合せ運転指令手段１１が位置調整用駆動装置５に駆動の指令を出し、その指令に従って位置調整用駆動装置５による床合せを行う。 In S105, based on the establishment of the conditional expression determined by the conditional expression calculation means 8, a selection is made to drive the position adjustment driving device 5 (upper and lower cars 26, 28). Further, as the floor alignment level as the driving amount, the upper car floor alignment level stored in the storage means 9 = (lower car floor displacement level 42−upper car floor displacement level 41) / 2 or lower car floor alignment level = (upper The floor alignment level is calculated by applying the upper car floor slip level 41 and the lower car floor slip level 42 using the mathematical formula of car floor slip level 41-lower car floor slip level 42) / 2. Then, the floor alignment operation command means 11 issues a drive command to the position adjustment drive device 5 to operate the position adjustment drive device 5 for the calculated floor alignment level, and the floor by the position adjustment drive device 5 according to the command. Align.

ここで、具体的な例を図５で説明する。図５は、この発明の実施の形態１におけるかご位置調整用駆動装置５で上下かごを動作させて床合わせを行う場合の一例を示す説明図である。まず、記憶手段９に記憶されている床合せ実施要否の閾値を例えば５ｍｍとする。その場合は、上かご床ずれレベル４１もしくは下かご床ずれレベル４２が閾値５ｍｍ以上、−５ｍｍ以下の時、床合せを実施する。｜上かご床ずれレベル４１＋下かご床ずれレベル４２｜／２≦閾値（５ｍｍ）の場合は上下かごを移動させる。例えば、上かご床ずれが５ｍｍで下かご床ずれ４２が−７ｍｍの場合は上かごを−６ｍｍ、下かごを６ｍｍ移動させる。それにより上かごの床ずれ４１は−１ｍｍ、下かご床ずれは１ｍｍとなり上下出入口とも閾値以内となる。このように、かご位置調整用駆動装置５の移動のみで、上下かごを閾値内に床合せすることが可能である。 Here, a specific example will be described with reference to FIG. FIG. 5 is an explanatory diagram showing an example in which floor matching is performed by operating the upper and lower cars with the car position adjusting drive device 5 according to the first embodiment of the present invention. First, the threshold for necessity of floor alignment stored in the storage means 9 is set to 5 mm, for example. In this case, when the upper car floor slip level 41 or the lower car floor slip level 42 is not less than the threshold value 5 mm and not more than −5 mm, floor matching is performed. When upper car floor slip level 41 + lower car floor slip level 42 | / 2 ≦ threshold (5 mm), the upper and lower cars are moved. For example, when the upper car floor slip is 5 mm and the lower car floor slip 42 is −7 mm, the upper car is moved by −6 mm and the lower car is moved by 6 mm. As a result, the floor slip 41 of the upper car is -1 mm, the floor slip of the lower car is 1 mm, and the upper and lower doors are within the threshold. In this way, it is possible to floor the upper and lower cars within the threshold only by moving the car position adjusting drive device 5.

Ｓ１０２及びＳ１０３の条件に当てはまらない場合（つまり、記憶手段９に記憶された床ずれの条件式｜上かご床ずれレベル４１＋下かご床ずれレベル４２｜／２＞閾値かつ｜上かご床ずれレベル４１−下かご床ずれレベル４２｜／２＞閾値が成立する場合）にはＳ１０４に進み、主駆動装置２０及び位置調整用駆動装置５を駆動するよう選択する。また、その駆動量である床合せレベルとしては、記憶手段９に記憶された主枠床合わせレベル＝−（上かご床ずれレベル４１＋下かご床ずれレベル４２）／２という数式を用いて主枠２４による床合わせレベルを演算し、さらに記憶手段９に記憶された上かご床合わせレベル＝（下かご床ずれレベル４２−上かご床ずれレベル４１）／２若しくは下かご床合わせレベル＝（上かご床ずれレベル４１−下かご床ずれレベル４２）／２という数式を用いて上かご床ずれレベル４１及び下かご床ずれレベル４２を当てはめて上下かご２６、２８による床合わせレベルを演算する。そして、主枠と上下かごでそれぞれ演算された床合わせレベル分主駆動装置２０と位置調整用駆動装置５を作動させるよう床合せ運転指令手段１１が主駆動装置２０と位置調整用駆動装置５の両者に駆動の指令を出し、その指令に従って主駆動装置２０及び位置調整用駆動装置５による床合せが行われる。 When the conditions of S102 and S103 are not satisfied (that is, the condition formula of floor slip stored in the storage means 9 | upper car floor slip level 41 + lower car floor slip level 42 | / 2> threshold and | upper car floor slip level 41−lower car floor slip If level 42 | / 2> threshold is satisfied), the process proceeds to S104, and the main drive unit 20 and the position adjustment drive unit 5 are selected to be driven. Further, as the floor alignment level that is the driving amount, the main frame floor alignment level stored in the storage means 9 = − (upper car floor displacement level 41 + lower car floor displacement level 42) / 2 is used. The floor level is calculated and the upper car floor level stored in the storage means 9 = (lower car floor slip level 42−upper car floor slip level 41) / 2 or lower car floor level = (upper car floor slip level 41− Using the mathematical formula of the lower car floor slip level 42) / 2, the upper car floor slip level 41 and the lower car floor slip level 42 are applied to calculate the floor matching level by the upper and lower cars 26, 28. Then, the floor alignment operation command means 11 controls the main drive device 20 and the position adjustment drive device 5 so as to operate the main drive device 20 and the position adjustment drive device 5 corresponding to the floor alignment levels calculated respectively in the main frame and the upper and lower cars. A drive command is issued to both, and floor matching is performed by the main drive device 20 and the position adjusting drive device 5 in accordance with the command.

ここで、具体的な例を図６で説明する。図６は、この発明の実施の形態１における主駆動装置及びかご位置調整用駆動装置で床合わせを行う場合の一例を示す説明図である。
まず、記憶手段９に記憶されている床合せ実施の閾値を例えば５ｍｍとする。その場合は、上かご床ずれ４１もしくは下かご床ずれ４２が閾値５ｍｍ以上、−５ｍｍ以下の時、床合せを実施する。例えば、上かご床ずれが３ｍｍで下かご床ずれ４２が１５ｍｍの場合は、主枠を−６ｍｍ移動させ、かつ上かごを３ｍｍ、下かごを−３ｍｍ移動させる。このように、上かごの床ずれ４１は０ｍｍ、下かご床ずれは０ｍｍとなり上下出入口とも床ずれレベルを０ｍｍにすることができる。Here, a specific example will be described with reference to FIG. FIG. 6 is an explanatory diagram showing an example in which floor alignment is performed by the main drive device and the car position adjustment drive device according to Embodiment 1 of the present invention.
First, the floor alignment threshold stored in the storage means 9 is set to 5 mm, for example. In this case, when the upper car floor slip 41 or the lower car floor slip 42 is a threshold value of 5 mm or more and −5 mm or less, floor matching is performed. For example, when the upper car floor slip is 3 mm and the lower car floor slip 42 is 15 mm, the main frame is moved by -6 mm, and the upper car is moved by 3 mm and the lower car is moved by -3 mm. Thus, the floor slip 41 of the upper car is 0 mm, the floor slip of the lower car is 0 mm, and the floor slip level can be set to 0 mm at the upper and lower doors.

この発明の実施の形態１によれば、上下かごの床ずれのレベルにより、床合せ方法を選択して行うことにより、扉が開いた状態で乗客が乗降した時でも、上下かごともに閾値内の床ずれレベルにおさえることが可能であり、最適な上下かごの床合せを実現することができる。   According to the first embodiment of the present invention, by selecting a floor alignment method according to the level of floor slip of the upper and lower cars, even when passengers get on and off with the door open, the floor slip is within the threshold value for both the upper and lower cars. It is possible to keep the level at an appropriate level, and it is possible to achieve the optimum floor matching of the upper and lower cars.

なお、上記では、かご装置５０が乗場に到着し、乗客が乗り降りした際に生じる床ずれの補正について説明したが、これに限らずかご装置５０が乗場に到着した際に生じる床ずれを補正する際にも同様の床合せを行うことができる。
また、上記の処理はマイコンのソフトウェアで処理するものであるが、これに限らず加減算回路等の回路を設けて加減算や閾値比較を行うこともできる。In the above description, the correction of the floor slip that occurs when the car device 50 arrives at the landing and the passengers get on and off is described. However, the present invention is not limited to this, and when the floor slip that occurs when the car device 50 arrives at the landing is corrected. The same flooring can be performed.
The above processing is performed by software of a microcomputer. However, the present invention is not limited to this, and addition / subtraction and threshold comparison can be performed by providing a circuit such as an addition / subtraction circuit.

実施の形態２．
次に、本実施の形態２におけるダブルデッキエレベーターについて説明する。なお、実施の形態１と同様の構成及び動作については適宜省略する。Embodiment 2. FIG.
Next, the double deck elevator according to the second embodiment will be described. Note that the same configuration and operation as those in Embodiment 1 are omitted as appropriate.

図７は、この発明の実施の形態２におけるダブルデッキエレベーターの動作を示すフローチャートである。図２及び図７において、床ずれレベル認識・判定手段７は、上かご検出センサ３７及び下かご検出センサ３９から入力された床ずれレベル４１、４２を認識する。また、床ずれレベル認識・判定手段７は、記憶手段９に記憶された閾値と床ずれレベル４１、４２を比較して、上かご２６もしくは下かご２８の少なくとも一方に床ずれがあるかどうかを判定する（Ｓ１１０）。   FIG. 7 is a flowchart showing the operation of the double deck elevator according to Embodiment 2 of the present invention. 2 and 7, the floor slip level recognition / determination means 7 recognizes the floor slip levels 41 and 42 input from the upper car detection sensor 37 and the lower car detection sensor 39. Further, the floor slip level recognition / determination means 7 compares the threshold value stored in the storage means 9 with the floor slip levels 41 and 42 to determine whether there is a floor slip in at least one of the upper car 26 or the lower car 28 ( S110).

その後に、かご内に設けられた車椅子釦装置の操作により登録されるかご内車椅子釦登録装置（図示略）あるいは乗場に設けられた車椅子釦装置の操作により登録される乗場車椅子釦登録装置（図示略）からの信号が入力されていると床ずれレベル認識・判定手段７は、Ｓ１１１で特定条件とみなしＳ１０４に進み、主駆動装置２０及び位置調整用駆動装置５による床合せが行われる。これは、車椅子利用者がエレベーターを利用する際に段差でつまずくのを防止するために、車椅子釦装置が押されたかごの床合せレベルを０にする必要があるためである。逆にかご内車椅子釦登録装置あるいは乗場車椅子釦登録装置からの信号が床ずれレベル認識・判定手段７に入力されていない場合には、床ずれレベル認識・判定手段７は特定条件でないと判断し、Ｓ１０２へ進む。 Thereafter, an in-car wheelchair button registration device (not shown) registered by operation of a wheelchair button device provided in the car or a landing wheelchair button registration device (not shown) registered by operation of a wheelchair button device provided in the hall If the signal from (omitted) is input, the floor displacement level recognition / determination means 7 regards the specific condition in S111 and proceeds to S104, where the main drive device 20 and the position adjustment drive device 5 perform floor alignment. This is because it is necessary to set the floor level of the car on which the wheelchair button device is pressed to 0 in order to prevent the wheelchair user from tripping at the step when using the elevator. Conversely, if the signal from the in-car wheelchair button registration device or the landing wheelchair button registration device is not input to the floor slip level recognition / determination means 7, it is determined that the floor slip level recognition / determination means 7 is not a specific condition, and S102 Proceed to

Ｓ１０２へ進むと床ずれレベル認識・判定手段７は、上かご２６もしくは下かご２８の少なくとも一方の床ずれレベルが閾値以上であるかを判定する（Ｓ１０１）。それ以降のフローは実施の形態１と同様であるため省略する。 In S102, the floor slip level recognition / determination means 7 determines whether the floor slip level of at least one of the upper car 26 or the lower car 28 is equal to or higher than a threshold value (S101). Since the subsequent flow is the same as that of the first embodiment, a description thereof will be omitted.

ここで、具体的な例を図８で説明する。図８は、この発明の実施の形態２における主駆動装置及びかご位置調整用駆動装置で床合わせを行う場合の一例を示す説明図である。
図において、床ずれが発生した場合、床合せを実施する。例えば、かご内や乗場の車椅子釦装置（図示略）が押されているなど、特定の条件がそろった場合は、主枠及び上下かご両方で床合せを行い、これは図６と同様である。上かご床ずれレベルが８ｍｍで下かご床ずれレベル４２が４ｍｍの場合は、主枠を−６ｍｍ移動させ、かつ上かごを−２ｍｍ、下かごを２ｍｍ移動させる。また、上かご床ずれレベルが３ｍｍで下かご床ずれレベル４２が７ｍｍの場合は、主枠を−５ｍｍ移動させ、かつ上かごを−２ｍｍ、下かごを２ｍｍ移動させる。A specific example will be described with reference to FIG. FIG. 8 is an explanatory diagram showing an example in which floor alignment is performed by the main drive device and the car position adjustment drive device according to Embodiment 2 of the present invention.
In the figure, when a floor slip occurs, floor alignment is performed. For example, when specific conditions are met, such as when a wheelchair button device (not shown) in a car or a hall is pressed, floor alignment is performed in both the main frame and the upper and lower cars, which is the same as FIG. . When the upper car floor slip level is 8 mm and the lower car floor slip level 42 is 4 mm, the main frame is moved by -6 mm, the upper car is moved by -2 mm, and the lower car is moved by 2 mm. When the upper car floor slip level is 3 mm and the lower car floor slip level 42 is 7 mm, the main frame is moved by -5 mm, the upper car is moved by -2 mm, and the lower car is moved by 2 mm.

この発明の実施の形態２によれば、上かごの床ずれレベル４１は０ｍｍ、下かご床ずれレベルは０ｍｍとなり、上下出入口とも床ずれレベルを０ｍｍにして上下かごの床間隔を乗場の階間距離６と等しくすることができ、エレベーター利用者の更なる安全性を実現できる。 According to the second embodiment of the present invention, the floor slip level 41 of the upper car is 0 mm, the floor slip level of the lower car is 0 mm, the floor slip level is 0 mm at both the upper and lower entrances, and the floor distance between the upper and lower cars is the floor distance 6 of the landing. It can be made equal, and further safety for elevator users can be realized.

実施の形態３．
次に、本実施の形態３におけるダブルデッキエレベーターについて説明する。なお、実施の形態１及び２と同様の構成及び動作については適宜省略する。Embodiment 3 FIG.
Next, the double deck elevator according to the third embodiment will be described. Note that configurations and operations similar to those in Embodiments 1 and 2 are omitted as appropriate.

図９は、この発明の実施の形態３における床合せ制御装置の機能を示す機能ブロック図であり、図１０は、この発明の実施の形態３におけるダブルデッキエレベーターの動作を示すフローチャートである。図２、図９及び図１０において、床ずれレベル認識・判定手段７は、上かご検出センサ３７及び下かご検出センサ３９から入力された床ずれレベル４１、４２を認識する。また、床ずれレベル認識・判定手段７は、記憶手段９に記憶された床ずれレベルの閾値と床ずれレベル４１、４２を比較して、上かご２６に生じた床ずれレベル４１もしくは下かご２８に生じた床ずれレベル４２の少なくとも一方が閾値以上であるかを判定する（Ｓ１０１）。閾値以上であった場合には、Ｓ１１２に進み、閾値未満であれば以降の処理を行わない。   FIG. 9 is a functional block diagram showing functions of the floor matching control apparatus according to Embodiment 3 of the present invention. FIG. 10 is a flowchart showing the operation of the double deck elevator according to Embodiment 3 of the present invention. 2, 9 and 10, the floor slip level recognition / determination means 7 recognizes the floor slip levels 41 and 42 input from the upper car detection sensor 37 and the lower car detection sensor 39. Further, the floor slip level recognition / determination means 7 compares the floor slip level threshold stored in the storage means 9 with the floor slip levels 41 and 42, and the floor slip level 41 generated in the upper car 26 or the floor slip generated in the lower car 28. It is determined whether at least one of the levels 42 is equal to or greater than a threshold value (S101). If it is equal to or greater than the threshold, the process proceeds to S112, and if it is less than the threshold, the subsequent processing is not performed.

Ｓ１１２では、床ずれレベル認識・判定手段７が判定した、上かご２６に生じた床ずれレベル４１もしくは下かご２８に生じた床ずれレベル４２の少なくとも一方が閾値以上である回数を床合せ制御装置１２に設けられた異常検出手段４３がカウントし、一定時間内に所定回数以上（例えば５回以上）であるかどうかを判断する。その結果、所定回数続いた場合は、経年変化により上下かごロープ３０、３３が伸びた、あるいは上下かごの負荷が極端に異なるようなアンバランス状態が生じて上下かごロープ３０、３３に滑りが生じたなどの異常状態が発生していると判断し、異常検出手段４３が異常を外部に通報し保守員の検査を促す。   In S112, the floor alignment control device 12 is provided with the number of times that at least one of the floor shift level 41 generated in the upper car 26 or the floor shift level 42 generated in the lower car 28 determined by the floor shift level recognition / determination means 7 is equal to or greater than a threshold value. The detected abnormality detecting means 43 counts and determines whether or not the predetermined number of times (for example, 5 times or more) is reached within a predetermined time. As a result, if it continues for a predetermined number of times, the upper and lower car ropes 30 and 33 are stretched due to aging, or an unbalanced state in which the load on the upper and lower car is extremely different occurs, causing the upper and lower car ropes 30 and 33 to slip. It is determined that an abnormal state such as that has occurred, and the abnormality detection means 43 notifies the abnormality to the outside and prompts maintenance personnel to inspect.

この発明の実施の形態３によれば、上下かごのロープの経年変化による伸びや上下かごの負荷アンバランスによる滑り等の異常状態を判断することができ、更なる乗客の安全氏を確保することができる。   According to the third embodiment of the present invention, it is possible to determine abnormal conditions such as elongation due to secular changes in the upper and lower car ropes and slipping due to load unbalance of the upper and lower cars, and to ensure further passenger safety. Can do.

また、上下かご２６、２８の主枠２４に対する相対的な床合せ速度が一定以上となった場合、床合せ機能を中止することもできる。例えば、かご位置調整用駆動装置５に設置された制御用の速度検出器（図示略）により検出された上かごの移動速度をＡ、主駆動装置２０に設置された速度検出器により検出された主枠の移動速度をＢとする。移動速度Ｃ＝Ａ＋Ｂは床ずれレベルを補正するときの乗場に対する上かごの相対速度であり速度Ｃ＞異常速度レベルとなった場合は、床合せを中止する。これにより、相対的な床合せ速度が異常状態であることが判断でき安全性を確保することができる。   Further, when the relative floor alignment speed of the upper and lower cars 26 and 28 with respect to the main frame 24 becomes a certain level or higher, the floor alignment function can be stopped. For example, the moving speed of the upper car detected by a control speed detector (not shown) installed in the car position adjusting drive 5 is detected by the speed detector installed in the main drive 20. Let B be the moving speed of the main frame. The moving speed C = A + B is the relative speed of the upper car with respect to the landing when correcting the floor slip level. If the speed C> the abnormal speed level, the floor alignment is stopped. As a result, it is possible to determine that the relative floor alignment speed is in an abnormal state and to ensure safety.
