この発明はエレベータのかご位置検出装置の改

ならない必要のあるエレベータには使用できなか
つた。 Conventionally, as a device for detecting the position of an elevator car, a detection device is installed in the car, and an element for operating the device is attached to a desired position in the hoistway to obtain electrical pulse signals and count them to detect the position of the car. is used to detect the position of
This position detection device has a complicated structure and has the disadvantage that if the pulse count becomes incorrect, the actual position of the car and the car position signal will not match, so it cannot accurately detect and control the position of the car. It could not be used for elevators that needed to be installed.

られている。 The simplest device for detecting the position of an elevator car is one in which a position switch is provided for each floor in the hoistway and these switches are sequentially operated by a cam attached to the car. Although the cam allows the position of the car to be reliably detected as long as the switch is operating, it has the disadvantage that the operating range of the switch is uniformly determined by the length of the cam. The control circuit of a general elevator is configured to compare the registered call and the car position and issue a stop command when the car reaches the call position. This is the distance from when a command is issued until the car stops, and this value changes depending on the driving speed of the elevator.)
The car position signal must be transferred to the next floor before this point. However, as the speed of the car increases and the required deceleration distance becomes longer, the above-mentioned conditions cannot be met, so this method is used exclusively in low-speed elevators.
この発明は上記欠点を解消するもので、階床間
の所要減速距離よりも手前でかご位置信号を次の

生じても確実に修正されるようにしたエレベータ
の位置検出装置を提供することを目的とする。 This invention solves the above-mentioned drawbacks, and it is possible to transfer the car position signal to the next floor before the required deceleration distance between floors, and it is also possible to reliably correct any deviation in the position signal. An object of the present invention is to provide a position detection device for an elevator.

様の動作が繰り返えされる。 Assuming that the car 5 is now on the first floor, the first detection device 1A engages with the cam 6 as shown in FIG.
Contact 1Aa is closed. Further, the third detection device 7 is engaged with the cam 1C, and the contact point 7a is closed. When the power (+) and (-) are turned on here,
(+)-7a-1Aa-1D-(-) circuit,
Position detection relay 1D on the first floor is energized and contact 1
Self-retained by closing Da. In addition, contact 1Db
is open. When the car 5 starts to rise, the upstream relay contacts 8a and 8b are closed. When the third detection device 7 moves away from the cam 1c, the contact 7a opens. However, as mentioned above, since the position detection relay 1D is self-holding, the position of the car 5 is 1.
floor has been detected. When the car 5 further rises and the second detection device 1B engages with the cam 6, the contact 1
Ba is closed, the position detection relay 2D on the second floor is energized by the circuit (+)-1Ba-8a-2D-(-), and the contacts 2Db and 2Dc are opened. By opening the contact 2Dc, the position detection relay 1D on the first floor is deenergized, the contact 1Da is opened, and the contact 1Db is closed.
Here, (+)-3Db-1Db-2Da-2D-
(-) circuit, position detection relay 2D on the second floor
is self-maintained. With this, the position of the second floor is detected, and if there is a call to the second floor, the car 5 can be stopped on the second floor. When the car 5 rises further and the cam 6 is removed from the first detection device 1A, the contact 1Aa is opened, or the second floor position detection relay 2D is already held, so no change occurs in the circuit. .
When the car 5 further rises and the first detection device 2A engages with the cam 6, the contact point 2Aa is closed. Next, when the cam 6 is removed from the second detection device 1B,
Contact 1Ba is open. Then, when the third detection device 7 engages with the cam 2C, the contact 7a is closed. In this way, the robot advances to the third floor, and the same operation is repeated when descending.

２Ｄは付勢され、同様に位置検出が行われる。 Next, assume that a power outage occurs while the car 5 is located, for example, between the first and second floors. At this time, if the third detection device 7 is not engaged with the cam 1c, the contact 7a is opened. Therefore, even if the power outage is restored, none of the position detection relays 1D to 3D are energized. However, at this time, if the cam 6 is engaged with the second detection device 1B and the car 5 is raised (the raising and lowering of the car 5 is performed by another circuit (not shown)). ), (+)-1Ba-8a
The detection relay 2D on the second floor is energized by the circuit -2D-(-), and position detection is immediately restored. If the cam 6 is not engaged with the second detection device 1B, if the car 5 rises and the third detection device 7 engages the cam 2C, then (+)-7a-2Aa-2
The position detection relay 2D on the second floor is energized by the circuit D-(-), and position detection is performed in the same way.

を直列に接続すればよい。 Note that if the required deceleration distance A is long and the operating ranges 1BX and 2BX of the second detection device cannot be obtained with one detection device 1B and 2B, respectively, multiple detection devices may be installed per floor. They can be placed one above the other with a certain distance between them, and their output contacts can be connected in parallel. On the other hand, if the required deceleration distance A is short and the operating ranges 1BX and 2BX are desired to be shortened, the output contacts may be connected in series.

In this way, it is only necessary to add the first and second detection switches 1A to 3A, 1B, and 2B, and the structure can be constructed at low cost.

ある。 As explained above, the present invention includes a first detection device corresponding to each floor and a second detection device corresponding to between each floor.
a detection device, and a third detection device that operates in a narrower range than the first detection device when the car is on the floor, and when the third detection device is not operating, the second detection device operates. When the car is operated, the car position is advanced to the next floor, and when the third detection device is activated, the car position is determined to be the floor indicated by the first detection device, regardless of the car position determined by the step. This is what I did.
これにより、少ない部品構成と簡単な回路によ
つて、階床間の所望位置でかご位置信号を次階へ
進めることができ、比較的長い所要減速距離を持
つエレベータにも適用できる。 As a result, the car position signal can be advanced to the next floor at a desired position between floors with a small number of parts and a simple circuit, and can also be applied to elevators that have a relatively long required deceleration distance.
