背景技術  Background art

On the other hand, there is a way to increase the size of the force. For this purpose, a large lifting machine with large torque and high output is required, which increases the production cost and the lifting and installation cost. On the other hand, there has been proposed an elevator apparatus that raises and lowers one force with two hoisting machines without increasing the size of the hoisting machine (see, for example, Patent Document 1).

It is a graph.
[0017] 力ご 1を急停止させる指令 (非常停止指令）が発生すると、モータ 9, 13への通電が 遮断されるとともに、ブレーキ装置 11, 15の電磁コイルが消勢される。時刻 T1にお いて、減速度 0が所定値（閾値） Ί 0を超えると、ブレーキ制御手段 17, 19は、電磁 コイルへの付勢指令を ONにする。これにより、ブレーキ装置 11, 15の制動力が低減 され、減速度 0が低下する。  [0017] When a command for suddenly stopping the force 1 (emergency stop command) is generated, power to the motors 9 and 13 is cut off and the electromagnetic coils of the brake devices 11 and 15 are de-energized. At time T1, when the deceleration 0 exceeds a predetermined value (threshold value) Ί 0, the brake control means 17 and 19 turn on the energizing command to the electromagnetic coil. As a result, the braking force of the brake devices 11 and 15 is reduced, and the deceleration 0 is lowered.
[0018] この後、時刻 T2において、減速度 γが所定値 γ 0よりも低くなると、ブレーキ制御手 段 17, 19は、電磁コイルへの付勢指令を OFFにする。これにより、ブレーキ装置 11 , 15の制動力が増大され、減速度 γが大きくなる。  [0018] Thereafter, when the deceleration γ becomes lower than the predetermined value γ 0 at time T2, the brake control means 17 and 19 turn off the energizing command to the electromagnetic coil.

Other configurations are the same as those in the second embodiment.
[0024] 図 4は図 1の卷上機 4, 5のうちの 1台の非常制動時の回転速度、電磁コイルへの付 勢指令、及び電磁コイルの電流の時間変化を示すグラフである。図において、時刻 T 1は、非常停止指令の発生を検出した時刻であり、このときの卷上機 4, 5の回転速度 は VOである。ブレーキ制御手段 17, 19は、制御速度の上下限値を士 VI、所定の減 速度を γ、時刻 T1からの経過時間を tとして、以下の演算を実行する。  [0024] FIG. 4 is a graph showing a temporal change in the rotational speed, the energizing command to the electromagnetic coil, and the current of the electromagnetic coil of one of the lifting machines 4 and 5 in FIG. In the figure, time T 1 is the time when the occurrence of an emergency stop command is detected, and the rotational speed of the hoisting machines 4 and 5 at this time is VO. The brake control means 17 and 19 execute the following calculation, assuming that the upper and lower limits of the control speed are VI, the predetermined deceleration is γ, and the elapsed time from time T1 is t.
[0025] V2 (t) = (V0+Vl) - y X t · · · (1)  [0025] V2 (t) = (V0 + Vl)-y X t (1)
V3 (t) = (VO— VI)— γ X t · · · (2)  V3 (t) = (VO— VI) — γ X t · · · (2)
上記の式 1は上限となる制御目標速度パターン、式 2は下限となる制御目標速度パ ターンである。 [0026] ブレーキ制御手段 17, 19は、そのときの卷上機 4, 5の回転速度 V (t)と制御目標 速度パターンとを比較し、 V(t)≤V3 (t)であれば、電磁コイルを付勢する。また、 V ( t)≥V2 (t)であれば、電磁コイルを消勢する。このようなアルゴリズムでブレーキ装置 11, 15を制御することにより、卷上機 4, 5は、所定の減速度 γ近傍の減速度で減速 され停止される。 Equation 1 above is the upper limit control target speed pattern, and Equation 2 is the lower limit control target speed pattern. [0026] The brake control means 17 and 19 compare the rotational speed V (t) of the hoisting machines 4 and 5 at that time with the control target speed pattern, and if V (t) ≤ V3 (t), Energize the electromagnetic coil. If V (t) ≥ V2 (t), the electromagnetic coil is deactivated. By controlling the brake devices 11 and 15 with such an algorithm, the lifting machines 4 and 5 are decelerated and stopped at a deceleration in the vicinity of a predetermined deceleration γ.
[0027] このように、卷上機 4, 5の減速度ではなぐ回転速度に応じて制動力を制御するこ とによっても、非常制動時に卷上機 4, 5をより適正に減速させ停止させることができる  [0027] In this way, the hoisting machines 4 and 5 can be more appropriately decelerated and stopped during emergency braking by controlling the braking force according to the rotational speed that is not the deceleration of the hoisting machines 4 and 5. be able to

Because the force is controlled, the hoisting machines 4 and 5 can be decelerated and stopped more appropriately during emergency braking. In addition, since one brake control means 21 is used for the first and second lifting machines 4, 5, the number of brake control means 21 and speed detectors 18 can be reduced, thereby reducing the cost. can do.
