Further, the hoisting machine 12 has a drive sheave 18, a hoisting machine motor (not shown), and a pair of hoisting machine brakes 19. The hoisting machine motor rotates the drive sheave 18. The pair of hoist brakes 19 keeps the drive sheave 18 stationary. Further, the pair of hoisting machine brakes 19 brakes the rotation of the drive sheave 18.
　懸架体１３は、駆動シーブ１８に巻き掛けられている。懸架体１３としては、複数本のロープ又は複数本のベルトが用いられている。 The suspension body 13 is wound around the drive sheave 18. As the suspension body 13, a plurality of ropes or a plurality of belts are used.
　懸架体１３は、図１では図示されていない第１端部１３ａと、第２端部１３ｂとを有している。第１端部１３ａは、懸架体１３の長さ方向の一端部であり、巻き取り装置１６内に位置している。第２端部１３ｂは、懸架体１３の長さ方向の他端部であり、機械室１１に接続されている。 The suspension body 13 has a first end portion 13a and a second end portion 13b (not shown in FIG. 1). The first end portion 13a is one end portion in the length direction of the suspension body 13 and is located in the winding device 16. The second end portion 13b is the other end portion of the suspension body 13 in the length direction and is connected to the machine room 11.
　かご１４及び釣合おもり１５は、機械室１１の下方に位置している。かご１４は、かご本体２０と、回転可能なかご吊り車２１とを有している。釣合おもり１５は、おもり本体２２と、回転可能な釣合おもり吊り車２３とを有している。 The car 14 and the balance weight 15 are located below the machine room 11. The car 14 has a car main body 20 and a rotatable car suspension wheel 21. The balance weight 15 has a weight body 22 and a rotatable balance weight suspension wheel 23.
　懸架体１３は、巻き取り装置１６側から順に、かご吊り車２１、駆動シーブ１８、及び釣合おもり吊り車２３に巻き掛けられて、第２端部１３ｂに至っている。エレベータ装置１０のローピング方式は、２：１ローピング方式である。 The suspension body 13 is wound around the car suspension wheel 21, the drive sheave 18, and the balance weight suspension wheel 23 in this order from the winding device 16 side, and reaches the second end portion 13b. The roping method of the elevator device 10 is a 2: 1 roping method.
　かご１４は、懸架体１３によって昇降路２内に吊り下げられている。釣合おもり１５は、駆動シーブ１８に対してかご１４とは反対側で、懸架体１３によって昇降路２内に吊り下げられている。 The car 14 is suspended in the hoistway 2 by the suspension body 13. The balance weight 15 is suspended in the hoistway 2 by the suspension body 13 on the opposite side of the drive sheave 18 from the car 14.
　かご１４の通常運転時には、かご１４及び釣合おもり１５は、駆動シーブ１８を回転させることによって、昇降路２内を昇降する。即ち、エレベータ装置１０は、トラクション式エレベータである。但し、図１は、かご１４の通常運転時ではなく、機械室１１の上方向への移動時の状態を示している。 During normal operation of the car 14, the car 14 and the counterweight 15 move up and down in the hoistway 2 by rotating the drive sheave 18. That is, the elevator device 10 is a traction type elevator. However, FIG. 1 shows a state when the machine room 11 is moved upward, not during normal operation of the car 14.
　昇降路２内には、図示しない一対のかごガイドレールと、図示しない一対の釣合おもりガイドレールとが設置されている。一対のかごガイドレールは、かご１４の昇降を案内する。一対の釣合おもりガイドレールは、釣合おもり１５の昇降を案内する。 A pair of car guide rails (not shown) and a pair of balanced weight guide rails (not shown) are installed in the hoistway 2. The pair of car guide rails guides the car 14 to move up and down. The pair of balanced weight guide rails guide the ascending and descending of the balanced weight 15.
　巻き取り装置１６は、機械室１１に設けられている。巻き取り装置１６には、懸架体１３の一部が巻き取られている。 The take-up device 16 is provided in the machine room 11. A part of the suspension body 13 is wound around the winding device 16.
　制御装置１７は、巻上機１２を制御する。かご１４の通常運転時には、制御装置１７は、巻上機１２を制御することによって、かご１４の運行を制御する。 The control device 17 controls the hoisting machine 12. During normal operation of the car 14, the control device 17 controls the operation of the car 14 by controlling the hoisting machine 12.
　機械室１１の上方向への移動時には、かご１４は、昇降体揚重装置であるウインチ６を介して、機械室１１から吊り下げられている。図１のエレベータ装置１０における第１昇降体は、かご１４である。 When moving upward in the machine room 11, the car 14 is suspended from the machine room 11 via a winch 6 which is an elevating body lifting device. The first elevating body in the elevator device 10 of FIG. 1 is a car 14.
　また、機械室１１の上方向への移動時には、昇降路２内に支持台７が設置されており、釣合おもり１５が支持台７に支持されている。図１のエレベータ装置１０における第２昇降体は、釣合おもり１５である。 Further, when moving upward in the machine room 11, a support base 7 is installed in the hoistway 2, and the balance weight 15 is supported by the support base 7. The second elevating body in the elevator device 10 of FIG. 1 is a balance weight 15.
　機械室１１の上方向への移動時には、制御装置１７は、巻上機１２を制御することによって、駆動シーブ１８を回転駆動させる。このとき、駆動シーブ１８は、図１の時計方向へ回転され、駆動シーブ１８に対して釣合おもり１５側へ懸架体１３が供給される。懸架体１３は、機械室１１の移動量に応じた長さだけ、巻き取り装置１６から昇降路２内に引き出される。 When moving upward in the machine room 11, the control device 17 rotates the drive sheave 18 by controlling the hoisting machine 12. At this time, the drive sheave 18 is rotated clockwise in FIG. 1, and the suspension body 13 is supplied to the counterweight 15 side with respect to the drive sheave 18. The suspension body 13 is pulled out from the winding device 16 into the hoistway 2 by a length corresponding to the amount of movement of the machine room 11.
　巻き取り装置１６又は機械室１１には、図示しない引出阻止機構が設けられている。引出阻止機構は、かご１４の通常運転時に、巻き取り装置１６からの懸架体１３の引き出しを阻止する。 The take-up device 16 or the machine room 11 is provided with a pull-out prevention mechanism (not shown). The withdrawal blocking mechanism prevents the suspension body 13 from being pulled out from the take-up device 16 during the normal operation of the car 14.
　機械室１１の上方向への移動時には、引出阻止機構が解除される。引出阻止機構が解除された状態において、懸架体１３に対する巻き取り装置１６の保持力は、駆動シーブ１８と懸架体１３との間のトラクション力よりも小さい。 When moving upward in the machine room 11, the withdrawal prevention mechanism is released. With the withdrawal blocking mechanism released, the holding force of the take-up device 16 with respect to the suspension body 13 is smaller than the traction force between the drive sheave 18 and the suspension body 13.
　図２は、図１のエレベータ装置１０の要部を示すブロック図である。制御装置１７は、機能ブロックとして、駆動制御部１７ａ、トルク検出部１７ｂ、及び報知部１７ｃを有している。 FIG. 2 is a block diagram showing a main part of the elevator device 10 of FIG. The control device 17 has a drive control unit 17a, a torque detection unit 17b, and a notification unit 17c as functional blocks.
　駆動制御部１７ａは、巻上機モータの駆動、及び巻上機ブレーキ１９の動作を制御する。トルク検出部１７ｂは、巻上機１２からの信号に基づいて、駆動シーブ１８にかかるトルク負荷を検出する。 The drive control unit 17a controls the drive of the hoisting machine motor and the operation of the hoisting machine brake 19. The torque detection unit 17b detects the torque load applied to the drive sheave 18 based on the signal from the hoisting machine 12.
　駆動制御部１７ａは、機械室１１の上方向への移動時に、トルク検出部１７ｂからの信号に基づいて、巻上機１２のトルク負荷が設定範囲内となるように、巻上機１２を制御する。これによって、駆動制御部１７ａは、機械室１１の上方向への移動時に、懸架体１３の張力が設定範囲内となるように、巻上機１２を制御する。 The drive control unit 17a controls the hoisting machine 12 so that the torque load of the hoisting machine 12 is within the set range based on the signal from the torque detecting unit 17b when the machine room 11 moves upward. To do. As a result, the drive control unit 17a controls the hoisting machine 12 so that the tension of the suspension body 13 is within the set range when the machine room 11 moves upward.
　駆動制御部１７ａには、トルク負荷の第１設定値Ｔｓ１、トルク負荷の第２設定値Ｔｓ２、トルク負荷の下限値Ｔｍｉｎ、及びトルク負荷の上限値Ｔｍａｘが設定されている。 The drive control unit 17a is set with a first set value Ts1 for torque load, a second set value Ts2 for torque load, a lower limit value Tmin for torque load, and an upper limit value Tmax for torque load.
　第１設定値Ｔｓ１は、下限値Ｔｍｉｎよりも大きく、第２設定値Ｔｓ２よりも小さい値である。第２設定値Ｔｓ２は、上限値Ｔｍａｘよりも小さい値である。即ち、Ｔｍｉｎ＜Ｔｓ１＜Ｔｓ２＜Ｔｍａｘの関係が成り立っている。 The first set value Ts1 is larger than the lower limit value Tmin and smaller than the second set value Ts2. The second set value Ts2 is a value smaller than the upper limit value Tmax. That is, the relationship of Tmin <Ts1 <Ts2 <Tmax is established.
　また、第１設定値Ｔｓ１は、懸架体１３の張力の設定範囲の最低値に対応する値である。第２設定値Ｔｓ２は、懸架体１３の張力の設定範囲の最高値に対応する値である。下限値Ｔｍｉｎは、懸架体１３の張力の下限値に対応する値である。上限値Ｔｍａｘは、懸架体１３の張力の上限値に対応する値である。 The first set value Ts1 is a value corresponding to the lowest value in the tension setting range of the suspension body 13. The second set value Ts2 is a value corresponding to the maximum value of the tension setting range of the suspension body 13. The lower limit value Tmin is a value corresponding to the lower limit value of the tension of the suspension body 13. The upper limit value Tmax is a value corresponding to the upper limit value of the tension of the suspension body 13.
　機械室１１の上方向への移動時にトルク負荷の検出値Ｔｄが第１設定値Ｔｓ１よりも小さくなると、駆動制御部１７ａは、駆動シーブ１８の回転速度を低下させる。これにより、昇降路２内への懸架体１３の送り出し速度が低くなる。 When the torque load detection value Td becomes smaller than the first set value Ts1 when the machine room 11 moves upward, the drive control unit 17a reduces the rotation speed of the drive sheave 18. As a result, the delivery speed of the suspension body 13 into the hoistway 2 is reduced.
　機械室１１の上方向への移動時にトルク負荷の検出値Ｔｄが第２設定値Ｔｓ２よりも大きくなると、駆動制御部１７ａは、駆動シーブ１８の回転速度を高くする。これにより、昇降路２内への懸架体１３の送り出し速度が高くなる。 When the torque load detection value Td becomes larger than the second set value Ts2 when the machine room 11 moves upward, the drive control unit 17a increases the rotation speed of the drive sheave 18. As a result, the speed at which the suspension body 13 is sent into the hoistway 2 is increased.
　機械室１１の上方向への移動時にトルク負荷の検出値Ｔｄが下限値Ｔｍｉｎよりも小さくなると、駆動制御部１７ａは、駆動シーブ１８の回転を停止させる。これにより、昇降路２内への懸架体１３の送り出しが停止される。 When the torque load detection value Td becomes smaller than the lower limit value Tmin when the machine room 11 moves upward, the drive control unit 17a stops the rotation of the drive sheave 18. As a result, the delivery of the suspension body 13 into the hoistway 2 is stopped.
　機械室１１の上方向への移動時にトルク負荷の検出値Ｔｄが上限値Ｔｍａｘよりも大きくなると、報知部１７ｃは、機械室１１の移動を中止させるための作業中止指令を外部へ出力する。 When the torque load detection value Td becomes larger than the upper limit value Tmax when the machine room 11 moves upward, the notification unit 17c outputs a work stop command for stopping the movement of the machine room 11 to the outside.
　作業中止指令は、クレーン装置３を直接停止させる指令である。また、作業者がクレーン装置３を即座に停止させることが可能であれば、作業中止指令は、機械室１１の移動を中止すべき旨を作業者に伝える指令であってもよい。 The work stop command is a command to directly stop the crane device 3. Further, if the operator can immediately stop the crane device 3, the work stop command may be a command for informing the worker that the movement of the machine room 11 should be stopped.
　また、報知部１７ｃから作業中止指令が出力されると、駆動制御部１７ａは、駆動シーブ１８の回転を停止させる。 Further, when the work stop command is output from the notification unit 17c, the drive control unit 17a stops the rotation of the drive sheave 18.
　図３は、図１の機械室１１の上方向への移動時における制御装置１７の動作を示すフローチャートである。機械室１１を上昇させる作業が開始されると、制御装置１７は、ステップＳ１０１において、予め設定された速度で駆動シーブ１８を回転させる。 FIG. 3 is a flowchart showing the operation of the control device 17 when the machine room 11 of FIG. 1 is moved upward. When the work of raising the machine room 11 is started, the control device 17 rotates the drive sheave 18 at a preset speed in step S101.
　続いて、制御装置１７は、ステップＳ１０２において、トルク負荷の検出値Ｔｄが上限値Ｔｍａｘ以下であるかどうかを判定する。 Subsequently, in step S102, the control device 17 determines whether or not the torque load detection value Td is equal to or less than the upper limit value Tmax.
　検出値Ｔｄが上限値Ｔｍａｘ以下であれば、制御装置１７は、ステップＳ１０３において、トルク負荷の検出値Ｔｄが下限値Ｔｍｉｎ以上であるかどうかを判定する。 If the detected value Td is equal to or less than the upper limit value Tmax, the control device 17 determines in step S103 whether or not the detected value Td of the torque load is equal to or greater than the lower limit value Tmin.
　検出値Ｔｄが下限値Ｔｍｉｎ以上であれば、制御装置１７は、ステップＳ１０４において、トルク負荷の検出値Ｔｄが、第１設定値Ｔｓ１以上、第２設定値Ｔｓ２以下であるかどうかを判定する。 If the detected value Td is the lower limit value Tmin or more, the control device 17 determines in step S104 whether the detected value Td of the torque load is equal to or more than the first set value Ts1 and equal to or less than the second set value Ts2.
　検出値Ｔｄが第１設定値Ｔｓ１以上、第２設定値Ｔｓ２以下である場合、制御装置１７は、懸架体１３の張力が設定範囲内であると判定し、ステップＳ１０５において、機械室１１の移動作業を終了するかどうかを判定する。移動作業を終了するかどうかは、制御装置１７への作業終了信号の入力の有無によって判定される。 When the detected value Td is the first set value Ts1 or more and the second set value Ts2 or less, the control device 17 determines that the tension of the suspension body 13 is within the set range, and moves the machine room 11 in step S105. Determine if you want to finish the work. Whether or not to end the moving work is determined by the presence or absence of input of the work end signal to the control device 17.
　検出値Ｔｄが第１設定値Ｔｓ１よりも小さい場合、及び検出値Ｔｄが第２設定値Ｔｓ２よりも大きい場合、制御装置１７は、ステップＳ１０６において、駆動シーブ１８の速度を修正する。 When the detected value Td is smaller than the first set value Ts1 and the detected value Td is larger than the second set value Ts2, the control device 17 corrects the speed of the drive sheave 18 in step S106.
　検出値Ｔｄが第１設定値Ｔｓ１よりも小さい場合、制御装置１７は、予め設定された速度だけ駆動シーブ１８の速度を低下させる。検出値Ｔｄが第２設定値Ｔｓ２よりも大きい場合、制御装置１７は、予め設定された速度だけ駆動シーブ１８の速度を上昇させる。 When the detected value Td is smaller than the first set value Ts1, the control device 17 reduces the speed of the drive sheave 18 by a preset speed. When the detected value Td is larger than the second set value Ts2, the control device 17 increases the speed of the drive sheave 18 by a preset speed.
　制御装置１７は、ステップＳ１０５において、作業を終了しないと判定した場合、ステップＳ１０２からステップＳ１０６までの処理を繰り返し実行する。 When the control device 17 determines in step S105 that the work is not completed, the control device 17 repeatedly executes the processes from step S102 to step S106.
　ステップＳ１０３において、検出値Ｔｄが下限値Ｔｍｉｎよりも小さい場合、制御装置１７は、ステップＳ１０７において、駆動シーブ１８の回転を停止させる。この後、制御装置１７は、ステップＳ１０５において、機械室１１の移動作業を終了するかどうかを判定する。 If the detected value Td is smaller than the lower limit value Tmin in step S103, the control device 17 stops the rotation of the drive sheave 18 in step S107. After that, the control device 17 determines in step S105 whether or not to finish the moving work of the machine room 11.
　駆動シーブ１８の回転を停止させたまま機械室１１の上方向への移動が継続されると、トルク負荷は上昇することになる。そして、トルク負荷の検出値Ｔｄが下限値Ｔｍｉｎ以上となると、制御装置１７は、ステップＳ１０６において、駆動シーブ１８の回転速度を修正する。 If the upward movement of the machine room 11 is continued while the rotation of the drive sheave 18 is stopped, the torque load will increase. Then, when the detected value Td of the torque load becomes the lower limit value Tmin or more, the control device 17 corrects the rotation speed of the drive sheave 18 in step S106.
　制御装置１７は、ステップＳ１０５において、機械室１１の移動作業を終了すると判定した場合、ステップＳ１０８において、駆動シーブ１８の回転を停止させ、図３の処理を終了する。 When the control device 17 determines in step S105 that the movement work of the machine room 11 is completed, the control device 17 stops the rotation of the drive sheave 18 in step S108 and ends the process of FIG.
　また、制御装置１７は、ステップＳ１０２において、トルク負荷の検出値Ｔｄが上限値Ｔｍａｘよりも大きいと判定した場合、ステップＳ１０９において、作業中止指令を外部へ出力し、駆動シーブ１８の回転を停止させ、図３の処理を終了する。 Further, when the control device 17 determines in step S102 that the detected value Td of the torque load is larger than the upper limit value Tmax, the control device 17 outputs a work stop command to the outside in step S109 to stop the rotation of the drive sheave 18. , The process of FIG. 3 is completed.
　このようなエレベータ装置１０では、クレーン装置３によって機械室１１を上方向へ移動させることが可能となっている。このため、建物１の建築初期からエレベータ装置１０を建物１に設置し、建物１の高さが高くなるのに対応して、機械室１１を段階的に引き上げてエレベータの昇降行程を高くすることができる。 In such an elevator device 10, the machine room 11 can be moved upward by the crane device 3. Therefore, the elevator device 10 is installed in the building 1 from the initial stage of the construction of the building 1, and the machine room 11 is gradually raised in response to the increase in the height of the building 1 to increase the elevator lifting stroke. Can be done.
　また、機械室１１の上方向への移動時に、制御装置１７によって巻上機１２が制御されることによって、懸架体１３が昇降路２内に送り出される。このため、機械室１１の上方向への移動によるエレベータ装置１０の利用停止期間を短縮することができる。これによって、建物１の建築工事期間を短縮して、早期の工事完了を実現することができる。 Further, when the machine room 11 moves upward, the hoisting machine 12 is controlled by the control device 17, so that the suspension body 13 is sent out into the hoistway 2. Therefore, it is possible to shorten the period of suspension of use of the elevator device 10 due to the upward movement of the machine room 11. As a result, the construction period of the building 1 can be shortened and the construction can be completed at an early stage.
　また、機械室１１の上方向への移動時に、制御装置１７は、巻上機１２のトルク負荷に基づいて、懸架体１３の張力が設定範囲内となるように、巻上機１２を制御する。このため、機械室１１の移動速度に応じて、適切な量だけ懸架体１３を昇降路２内に自動的に送り出すことができる。即ち、懸架体１３の送り出し作業を自動化することができる。 Further, when the machine room 11 moves upward, the control device 17 controls the hoisting machine 12 so that the tension of the suspension body 13 is within the set range based on the torque load of the hoisting machine 12. .. Therefore, an appropriate amount of the suspension body 13 can be automatically sent out into the hoistway 2 according to the moving speed of the machine room 11. That is, the sending work of the suspension body 13 can be automated.
　これにより、懸架体１３が昇降路２内に余分に送り出されることが抑制され、余分な懸架体１３の巻き戻し作業の発生を防止することができる。また、懸架体１３の昇降路２内への送り出しが遅れて懸架体１３の張力が過大になることが抑制され、クレーン装置３の負担が過大になることを抑制することができる。 As a result, it is possible to prevent the suspension body 13 from being extraly sent out into the hoistway 2, and to prevent the extra suspension body 13 from being rewound. Further, it is possible to prevent the suspension body 13 from being delayed in being sent out into the hoistway 2 and the tension of the suspension body 13 from becoming excessive, and to prevent the load on the crane device 3 from becoming excessive.
　図４は、実施の形態１によるエレベータ装置１０の変形例を示す構成図である。この変形例では、機械室１１の上方向への移動時に、かご１４が支持台７に支持されている。図４のエレベータ装置１０における第２昇降体は、かご１４である。 FIG. 4 is a configuration diagram showing a modified example of the elevator device 10 according to the first embodiment. In this modification, the car 14 is supported by the support base 7 when the machine room 11 is moved upward. The second elevating body in the elevator device 10 of FIG. 4 is a car 14.
　また、機械室１１の上方向への移動時に、釣合おもり１５が、ウインチ６を介して、機械室１１から吊り下げられている。図４のエレベータ装置１０における第１昇降体は、釣合おもり１５である。 Further, when the machine room 11 is moved upward, the balance weight 15 is suspended from the machine room 11 via the winch 6. The first elevating body in the elevator device 10 of FIG. 4 is a balance weight 15.
　懸架体１３の第２端部１３ｂは、巻き取り装置１６内に位置している。懸架体１３は、第１端部１３ａ側から順に、かご吊り車２１、駆動シーブ１８、及び釣合おもり吊り車２３に巻き掛けられて、巻き取り装置１６に至っている。 The second end portion 13b of the suspension body 13 is located in the take-up device 16. The suspension body 13 is wound around the car suspension wheel 21, the drive sheave 18, and the balance weight suspension wheel 23 in this order from the first end portion 13a side to reach the winding device 16.
　機械室１１の上方向への移動時には、駆動シーブ１８は、図４の反時計方向へ回転され、駆動シーブ１８に対してかご１４側へ懸架体１３が供給される。他の構成及び制御方法は、図１～３に示した例と同様である。 When the machine room 11 moves upward, the drive sheave 18 is rotated counterclockwise in FIG. 4, and the suspension body 13 is supplied to the car 14 side with respect to the drive sheave 18. Other configurations and control methods are the same as the examples shown in FIGS. 1 to 3.
　このように、釣合おもり１５が機械室１１から吊り下げられ、かご１４が支持台７に支持されている構成においても、図１～３に示した例と同様の効果を得ることができる。 In this way, even in a configuration in which the balance weight 15 is suspended from the machine room 11 and the car 14 is supported by the support base 7, the same effect as the examples shown in FIGS. 1 to 3 can be obtained.
　実施の形態２．
　次に、図５は、実施の形態２によるエレベータ装置１０の要部を示すブロック図である。実施の形態２の制御装置１７は、機能ブロックとして、駆動制御部１７ａ、情報取得部１７ｄ、追従判定部１７ｅ、及び報知部１７ｃを有している。 Embodiment 2.
Next, FIG. 5 is a block diagram showing a main part of the elevator device 10 according to the second embodiment. The control device 17 of the second embodiment has a drive control unit 17a, an information acquisition unit 17d, a follow-up determination unit 17e, and a notification unit 17c as functional blocks.
　情報取得部１７ｄは、機械室１１の上方向への移動時に、機械室１１の移動に関する情報である移動情報を外部から取得する。移動情報は、例えば、機械室１１の移動量及び移動速度の少なくともいずれか１つの情報を含んでいる。 The information acquisition unit 17d acquires movement information, which is information related to the movement of the machine room 11, from the outside when the machine room 11 moves upward. The movement information includes, for example, at least one information of the movement amount and the movement speed of the machine room 11.
　また、移動情報は、駆動状態信号、クレーン制御信号、クレーン検出信号、及び機械室検出信号の少なくとも１つの信号から得ることができる。 Further, the movement information can be obtained from at least one signal of the drive state signal, the crane control signal, the crane detection signal, and the machine room detection signal.
　駆動状態信号は、クレーン装置３の駆動状態に応じた信号であり、クレーン装置３の駆動部から出力される。クレーン制御信号は、クレーン装置３を制御する信号である。クレーン検出信号は、クレーン装置３の実際の動作を検出するセンサからの信号である。機械室検出信号は、機械室１１の移動を直接検出するセンサからの信号である。 The drive state signal is a signal corresponding to the drive state of the crane device 3, and is output from the drive unit of the crane device 3. The crane control signal is a signal for controlling the crane device 3. The crane detection signal is a signal from a sensor that detects the actual operation of the crane device 3. The machine room detection signal is a signal from a sensor that directly detects the movement of the machine room 11.
　駆動制御部１７ａは、機械室１１の上方向への移動時に、情報取得部１７ｄからの情報に基づいて、機械室１１の移動に追従するように、巻上機１２を制御して、懸架体１３を昇降路２内に供給させる。 When the drive control unit 17a moves upward in the machine room 11, the drive control unit 17a controls the hoisting machine 12 so as to follow the movement of the machine room 11 based on the information from the information acquisition unit 17d, and is a suspension body. 13 is supplied into the hoistway 2.
　追従判定部１７ｅは、機械室１１の上方向への移動時に、情報取得部１７ｄからの情報と、駆動制御部１７ａからの情報とに基づいて、懸架体１３の供給が機械室１１の移動に追従可能であるかどうかを判定する。 When the follow-up determination unit 17e moves upward in the machine room 11, the supply of the suspension body 13 moves to the machine room 11 based on the information from the information acquisition unit 17d and the information from the drive control unit 17a. Determine if it can be followed.
　機械室１１の上方向への移動時に、懸架体１３の供給が機械室１１の移動に追従不可であると判定されると、報知部１７ｃは、機械室１１の移動を中止させるための作業中止指令を外部へ出力する。 When it is determined that the supply of the suspension body 13 cannot follow the movement of the machine room 11 during the upward movement of the machine room 11, the notification unit 17c stops the work for stopping the movement of the machine room 11. Output the command to the outside.
　図５に示した制御装置１７の機能を除く、エレベータ装置１０の全体構成は、図１又は図４と同様である。 Except for the function of the control device 17 shown in FIG. 5, the overall configuration of the elevator device 10 is the same as that of FIG. 1 or FIG.
　図６は、機械室１１の上方向への移動時における図５の制御装置１７の動作を示すフローチャートである。機械室１１を上昇させる作業が開始されると、制御装置１７は、ステップＳ２０１において、移動情報を取得する。 FIG. 6 is a flowchart showing the operation of the control device 17 of FIG. 5 when the machine room 11 is moving upward. When the work of raising the machine room 11 is started, the control device 17 acquires the movement information in step S201.
　続いて、制御装置１７は、ステップＳ２０２において、機械室１１の移動に追従する駆動指令を演算し、演算した駆動指令を巻上機１２に出力する。 Subsequently, in step S202, the control device 17 calculates a drive command that follows the movement of the machine room 11, and outputs the calculated drive command to the hoisting machine 12.
　この後、制御装置１７は、ステップＳ２０３において、演算した駆動指令が機械室１１の移動に追従可能なものであるかどうかを判定する。 After that, the control device 17 determines in step S203 whether or not the calculated drive command can follow the movement of the machine room 11.
　ステップＳ２０３における判定結果が「追従可能」である場合、制御装置１７は、ステップＳ２０４において、機械室１１の移動作業を終了するかどうかを判定する。移動作業を終了するかどうかは、制御装置１７への作業終了信号の入力の有無によって判定される。 When the determination result in step S203 is "followable", the control device 17 determines in step S204 whether or not to end the movement work of the machine room 11. Whether or not to end the moving work is determined by the presence or absence of input of the work end signal to the control device 17.
　制御装置１７は、ステップＳ２０４において、作業を終了しないと判定した場合、ステップＳ２０１からステップＳ２０４までの処理を繰り返し実行する。 When the control device 17 determines in step S204 that the work is not completed, the control device 17 repeatedly executes the processes from step S201 to step S204.
　制御装置１７は、ステップＳ２０４において、機械室１１の移動作業を終了すると判定した場合、ステップＳ２０５において、駆動シーブ１８の回転を停止させる指令を巻上機１２に出力し、図６の処理を終了する。 When the control device 17 determines in step S204 that the movement work of the machine room 11 is completed, the control device 17 outputs a command to stop the rotation of the drive sheave 18 to the hoisting machine 12 in step S205, and ends the process of FIG. To do.
　クレーン装置３による機械室１１の移動速度が、巻上機１２による懸架体１３の供給能力を超えた場合、制御装置１７は、ステップＳ２０３において、「追従不可」と判定する。この場合、制御装置１７は、ステップＳ２０６において、作業中止指令を外部へ出力し、駆動シーブ１８の回転を停止させ、図６の処理を終了する。 When the moving speed of the machine room 11 by the crane device 3 exceeds the supply capacity of the suspension body 13 by the hoisting machine 12, the control device 17 determines in step S203 that it cannot follow. In this case, in step S206, the control device 17 outputs a work stop command to the outside, stops the rotation of the drive sheave 18, and ends the process of FIG.
　このように、クレーン装置３による機械室１１の引上動作に合わせて、巻上機１２を制御する構成によっても、実施の形態１と同様の効果を得ることができる。 As described above, the same effect as that of the first embodiment can be obtained by the configuration in which the hoisting machine 12 is controlled according to the pulling operation of the machine room 11 by the crane device 3.
　実施の形態３．
　次に、図７は、実施の形態３によるエレベータ装置１０を示す構成図である。実施の形態３では、機械室１１に張力検出装置５１が設けられている。張力検出装置５１は、第２端部１３ｂにおいて懸架体１３の張力を検出し、懸架体１３の張力に応じた信号を出力する。 Embodiment 3.
Next, FIG. 7 is a configuration diagram showing the elevator device 10 according to the third embodiment. In the third embodiment, the tension detecting device 51 is provided in the machine room 11. The tension detection device 51 detects the tension of the suspension body 13 at the second end portion 13b, and outputs a signal corresponding to the tension of the suspension body 13.
　図８は、図７のエレベータ装置１０の要部を示すブロック図である。制御装置１７は、駆動制御部１７ａ、張力監視部１７ｇ、及び報知部１７ｃを有している。 FIG. 8 is a block diagram showing a main part of the elevator device 10 of FIG. The control device 17 has a drive control unit 17a, a tension monitoring unit 17g, and a notification unit 17c.
　張力監視部１７ｇは、張力検出装置５１からの信号に基づいて、懸架体１３の張力が設定範囲内にあるかどうかを監視する。駆動制御部１７ａは、機械室１１の上方向への移動時に、張力監視部１７ｇからの信号に基づいて、懸架体１３の張力が設定範囲内となるように、巻上機１２を制御する。 The tension monitoring unit 17g monitors whether the tension of the suspension body 13 is within the set range based on the signal from the tension detection device 51. The drive control unit 17a controls the hoisting machine 12 so that the tension of the suspension body 13 is within the set range based on the signal from the tension monitoring unit 17g when the machine room 11 moves upward.
　報知部１７ｃは、機械室１１の上方向への移動時に、懸架体１３の張力の検出値が上限値よりも大きくなると、機械室１１の移動を中止させるための作業中止指令を外部へ出力する。 When the detection value of the tension of the suspension body 13 becomes larger than the upper limit value when the machine room 11 is moving upward, the notification unit 17c outputs a work stop command for stopping the movement of the machine room 11 to the outside. ..
　制御装置１７の具体的な動作は、図３と同様である。但し、実施の形態３では、図３のＴｄを張力の検出値、Ｔｍａｘを張力の上限値、Ｔｍｉｎを張力の下限値、Ｔｓ１を張力の第１設定値、Ｔｓ２を張力の第２設定値とする。 The specific operation of the control device 17 is the same as that in FIG. However, in the third embodiment, Td in FIG. 3 is the detected value of tension, Tmax is the upper limit value of tension, Tmin is the lower limit value of tension, Ts1 is the first set value of tension, and Ts2 is the second set value of tension. To do.
　張力検出装置５１によって検出された懸架体１３の張力に基づいて巻上機１２を制御する点を除いて、エレベータ装置１０の構成及び制御方法は、実施の形態１と同様である。 The configuration and control method of the elevator device 10 are the same as those of the first embodiment, except that the hoisting machine 12 is controlled based on the tension of the suspension body 13 detected by the tension detection device 51.
　このように、懸架体１３の張力を張力検出装置５１によって直接検出する構成によっても、実施の形態１と同様の効果を得ることができる。 As described above, the same effect as that of the first embodiment can be obtained by the configuration in which the tension of the suspension body 13 is directly detected by the tension detection device 51.
　なお、実施の形態３の構成は、図４に示した変形例にも適用できる。その場合、張力検出装置５１は、第１端部１３ａにおいて懸架体１３の張力を検出する。 Note that the configuration of the third embodiment can be applied to the modified example shown in FIG. In that case, the tension detecting device 51 detects the tension of the suspension body 13 at the first end portion 13a.
　実施の形態４．
　次に、図９は、実施の形態４によるエレベータ装置１０の巻上機１２を示す構成図である。実施の形態４の巻上機１２には、複数の摩擦力増大機構３１が設けられている。複数の摩擦力増大機構３１は、駆動シーブ１８の径方向外側に配置されている。また、複数の摩擦力増大機構３１は、駆動シーブ１８の周方向に互いに等間隔をおいて配置されている。図９では、３つの摩擦力増大機構３１が用いられている。 Embodiment 4.
Next, FIG. 9 is a configuration diagram showing a hoisting machine 12 of the elevator device 10 according to the fourth embodiment. The hoisting machine 12 of the fourth embodiment is provided with a plurality of frictional force increasing mechanisms 31. The plurality of frictional force increasing mechanisms 31 are arranged on the radial outer side of the drive sheave 18. Further, the plurality of frictional force increasing mechanisms 31 are arranged at equal intervals with each other in the circumferential direction of the drive sheave 18. In FIG. 9, three frictional force increasing mechanisms 31 are used.
　各摩擦力増大機構３１は、駆動シーブ１８の中心へ向かって、懸架体１３を駆動シーブ１８に押し付けている。これにより、各摩擦力増大機構３１は、懸架体１３と駆動シーブ１８との間の摩擦力を増大させている。また、各摩擦力増大機構３１は、ローラ保持部３２、押付ローラ３３、及び環状の接触部材３４を有している。 Each friction force increasing mechanism 31 presses the suspension body 13 against the drive sheave 18 toward the center of the drive sheave 18. As a result, each friction force increasing mechanism 31 increases the frictional force between the suspension body 13 and the drive sheave 18. Further, each friction force increasing mechanism 31 has a roller holding portion 32, a pressing roller 33, and an annular contact member 34.
　押付ローラ３３は、ローラ保持部３２に回転可能に支持されている。ローラ保持部３２は、押付ローラ３３を懸架体１３に押し付ける力を発生している。接触部材３４は、押付ローラ３３の外周に設けられており、懸架体１３に接触している。接触部材３４の材料としては、例えば、ゴム又は樹脂が用いられている。 The pressing roller 33 is rotatably supported by the roller holding portion 32. The roller holding portion 32 generates a force for pressing the pressing roller 33 against the suspension body 13. The contact member 34 is provided on the outer periphery of the pressing roller 33 and is in contact with the suspension body 13. As the material of the contact member 34, for example, rubber or resin is used.
　図９に示した巻上機１２の構成を除くエレベータ装置１０の全体構成及び制御装置１７の機能は、実施の形態１、２又は３と同様である。 The overall configuration of the elevator device 10 and the functions of the control device 17 except for the configuration of the hoisting machine 12 shown in FIG. 9 are the same as those of the first, second, and third embodiments.
　ここで、トラクション式のエレベータ装置１０では、懸架体１３と駆動シーブ１８との間に働く摩擦力によって、懸架体１３が送り出される。このため、摩擦力よりも大きな荷重が懸架体１３にかかると、意図した通りに懸架体１３を送り出すことができない。 Here, in the traction type elevator device 10, the suspension body 13 is sent out by the frictional force acting between the suspension body 13 and the drive sheave 18. Therefore, if a load larger than the frictional force is applied to the suspension body 13, the suspension body 13 cannot be delivered as intended.
　例えば、図１の構成では、駆動シーブ１８からかご吊り車２１までの懸架体１３の長さよりも、駆動シーブ１８から釣合おもり吊り車２３までの懸架体１３の長さが長い。このため、懸架体１３の偏った荷重が、駆動シーブ１８に作用する。 For example, in the configuration of FIG. 1, the length of the suspension body 13 from the drive sheave 18 to the balance weight suspension vehicle 23 is longer than the length of the suspension body 13 from the drive sheave 18 to the car suspension vehicle 21. Therefore, the unbalanced load of the suspension body 13 acts on the drive sheave 18.
　この懸架体１３の偏った荷重は、機械室１１が上方向へ移動する程大きくなる。そして、懸架体１３の偏った荷重が、懸架体１３と駆動シーブ１８との間に働く摩擦力よりも大きくなると、懸架体１３は、駆動シーブ１８の回転動作によらず、釣合おもり１５側へ送り出されることになる。 The unbalanced load of the suspension body 13 increases as the machine room 11 moves upward. Then, when the unbalanced load of the suspension body 13 becomes larger than the frictional force acting between the suspension body 13 and the drive sheave 18, the suspension body 13 is on the balance weight 15 side regardless of the rotational operation of the drive sheave 18. Will be sent to.
　その結果、懸架体１３が巻き取り装置１６から過剰に繰り出され、機械室１１を引き上げた後に懸架体１３が緩んだ状態となり、余分な懸架体１３の巻き戻し作業が必要となる。 As a result, the suspension body 13 is excessively unwound from the winding device 16, and after the machine room 11 is pulled up, the suspension body 13 becomes loose, and extra rewinding work of the suspension body 13 is required.
　これに対して、実施の形態４では、複数の摩擦力増大機構３１によって、懸架体１３が駆動シーブ１８に押し付けられており、懸架体１３と駆動シーブ１８との間の摩擦力が増大されている。このため、駆動シーブ１８からかご１４までの距離と、駆動シーブ１８から釣合おもり１５までの距離との差が大きくなっても、懸架体１３が意図せず送り出されることを抑制することができる。 On the other hand, in the fourth embodiment, the suspension body 13 is pressed against the drive sheave 18 by the plurality of friction force increasing mechanisms 31, and the frictional force between the suspension body 13 and the drive sheave 18 is increased. There is. Therefore, even if the difference between the distance from the drive sheave 18 to the car 14 and the distance from the drive sheave 18 to the balance weight 15 becomes large, it is possible to prevent the suspension body 13 from being unintentionally sent out. ..
　なお、懸架体１３に対する摩擦力増大機構３１の押付力は、駆動シーブ１８に作用する懸架体１３の偏った荷重が最大になったときにも、駆動シーブ１８上に懸架体１３を保持できる最低限の力とすることが好ましい。これにより、摩擦力増大機構３１による懸架体１３及び駆動シーブ１８の摩耗損傷を抑制することができる。 The pressing force of the frictional force increasing mechanism 31 against the suspension body 13 is the minimum that can hold the suspension body 13 on the drive sheave 18 even when the unbalanced load of the suspension body 13 acting on the drive sheave 18 is maximized. It is preferable to use the limit force. As a result, wear damage to the suspension body 13 and the drive sheave 18 due to the frictional force increasing mechanism 31 can be suppressed.
　駆動シーブ１８に作用する懸架体１３の偏った荷重は、建物１が完成し、昇降路２の上下方向寸法が最大となったときに最大となる。このため、例えば、建物１の完成時に駆動シーブ１８に作用する懸架体１３の偏った荷重を想定して、必要最小限のトラクション能力が確保できるように、各摩擦力増大機構３１の押付力を設計すればよい。 The unbalanced load of the suspension body 13 acting on the drive sheave 18 becomes maximum when the building 1 is completed and the vertical dimension of the hoistway 2 becomes maximum. Therefore, for example, assuming an unbalanced load of the suspension body 13 acting on the drive sheave 18 when the building 1 is completed, the pressing force of each friction force increasing mechanism 31 is increased so that the minimum necessary traction capacity can be secured. You can design it.
　なお、摩擦力増大機構の数は、１つ又は２つであっても、４つ以上であってもよい。 The number of frictional force increasing mechanisms may be one, two, or four or more.

The hoisting machine 12 of the fifth embodiment is provided with a frictional force increasing mechanism 41. The frictional force increasing mechanism 41 presses the suspension body 13 against the drive sheave 18 toward the center of the drive sheave 18. As a result, the frictional force increasing mechanism 41 increases the frictional force between the suspension body 13 and the drive sheave 18.
　また、摩擦力増大機構４１は、第１ローラ４２、第２ローラ４３、第３ローラ４４、及び無端状の押付ベルト４５を有している。第１ローラ４２及び第２ローラ４３は、駆動シーブ１８の左右に配置されている。第３ローラ４４は、駆動シーブ１８の真上に配置されている。 Further, the frictional force increasing mechanism 41 has a first roller 42, a second roller 43, a third roller 44, and an endless pressing belt 45.

　また、押付ベルト４５が懸架体１３に押し付けられるため、懸架体１３及び駆動シーブ１８に加わる力を駆動シーブ１８の周方向に分散させることができる。このため、懸架体１３及び駆動シーブ１８の摩耗損傷を抑制することができる。 Further, since the pressing belt 45 is pressed against the suspension body 13, the force applied to the suspension body 13 and the drive sheave 18 can be dispersed in the circumferential direction of the drive sheave 18. Therefore, wear damage of the suspension body 13 and the drive sheave 18 can be suppressed.

　このようなエレベータ装置１０では、懸架体１３の偏った荷重が、駆動シーブ１８と懸架体１３との間の摩擦力よりも大きくなった場合でも、懸架体１３を駆動シーブ１８上に保持することができる。また、保持装置５２の保持力を調整することによって、巻上機１２を駆動した場合にだけ巻き取り装置１６から懸架体１３を繰り出すことも可能である。 In such an elevator device 10, even if the unbalanced load of the suspension body 13 becomes larger than the frictional force between the drive sheave 18 and the suspension body 13, the suspension body 13 is held on the drive sheave 18.

This modification is an example in which the holding device 52 is added to the elevator device of FIG. In this example, the holding device 52 holds the suspension body 13 between the winding device 16 and the counterweight suspension wheel 23.
　保持装置５２は、駆動シーブ１８と巻き取り装置１６との間において懸架体１３を保持すればよい。このため、図１１の構成において、保持装置５２は、駆動シーブ１８とかご吊り車２１との間において、懸架体１３を保持してもよい。また、図１３の構成において、保持装置５２は、駆動シーブ１８と釣合おもり吊り車２３との間において、懸架体１３を保持してもよい。 The holding device 52 may hold the suspension body 13 between the drive sheave 18 and the take-up device 16.
