Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an elevator operation switching device,
In particular, the present invention relates to an elevator operation switching device that is suitable for allowing only specific people to use elevators at specific times such as nighttime in residential buildings or rental offices.

[Background of the invention]

The conventional elevator suspension device is
As shown in Publication No. 54-175768, a single operation stop switch is provided for temporary operation, and temporary operation can be canceled by operating a code on the platform button. It is proposed to do so.
However, there is a possibility that a third party will be able to detect the cryptographic operation, and in these days when security is strongly discouraged, a key-operated switch is often installed to be on the safe side. However, if a switch is provided only on one floor when the elevator is temporarily used, it is virtually impossible to use the elevator.

[Purpose of the invention]

The present invention has been made in view of the above, and its purpose is to provide a rational elevator operation switching device that can operate and stop the elevator from each floor.

[Summary of the invention]

A feature of the present invention is that each floor is equipped with a parking switch that switches the elevator between the operable state and the idle state, and the elevator can be switched between the operable state and the idle state by operating the parking switch on any floor. circuit means, and a control means that, when switched to the operable state, makes it impossible to switch to the rest state until the vehicle is operated to the destination call registration floor and then stopped, or even if it is not operated, a predetermined period of time has elapsed. The point is that it has a unique structure.

[Embodiments of the invention]

The present invention will be explained in detail below using the embodiments shown in FIGS. 1 to 3.

FIG. 1 is a layout diagram showing one embodiment of the arrangement of parking switches in the elevator operation switching device of the present invention, and illustrates the case of a fifth floor. In Figure 1, 1F to 5F indicate the 1st to 5th floors;

OK normally open contact, OK ₂ is relay OK normally closed contact,
CH is car call operation detection relay, CH ₁ is relay
CH normally open contacts, CH ₂ and CH ₄ are relay CH normally closed contacts, T is a timer for call escape detection, T ₂ is a normally closed contact for timer T, OP ₁ and OP ₃ are running detection relays (not shown). HY ₂ is the normally closed contact of the hall call detection relay (not shown), CY ₁ is the normally open contact of the car call detection relay (not shown), MS is the car call/hall call registration circuit These are connected to the power supply as shown.

Next, the operation shown in FIG. 3 will be explained. first,
If the status of parking switches 1P to 5P is as shown by the solid line in Figure 3, confirmation relay 1PR,
Both 2PR are off, which also turns off confirmation relay 3PR. Therefore, no parking command is issued and the elevator is ready for operation.

Now, assume that the parking switch 1P is switched to the lower side. As a result, the circuit between the parking switches 1P and 2P is closed, and the confirmation relay 1PR is turned on. As a result, contact _1PR1 is closed, confirmation relay 3PR is turned on, contact _3PR1 is closed, and parking command relay PK is turned on.
When relay PK is turned on, its contact PK ₄ is opened, so the car call/hall call registration circuit MS is disconnected, and the elevator can no longer be used. Similarly, the parking lights 1L to 5L are lit by the closing of the contact PK ₃ , indicating that the elevator has entered the idle state.

Next, a case will be described in which a resident on the third floor uses the elevator to go to the first floor during the above-mentioned dormant state.

First, when the parking switch 3P is switched to the lower side, the circuit between the parking switches 3P and 4P is closed, the confirmation relay 2PR is turned on, and the confirmation relay 3PR is turned off by opening the contact 2PR ₂ .
When the contact _3PR1 is opened, the parking command relay PK is turned off. Therefore, the contact point PK ₄
Car call/platform call registration circuit MS
becomes effective, and at the same time, the parking lights 1L to 5L go out due to the opening of contact PK ₃ , indicating that the elevator is ready for operation.

If you press the platform call button 3IH on the 3rd floor (see Figure 1), the platform call will be registered, the elevator will operate towards the 3rd floor, and when you get on the elevator and press the car call button on the 1st floor, The car call is registered and the elevator is operated towards the first floor. Then, when you get off the car after reaching the 1st floor and switch the parking switch 1P to the upper side, 1PR off → 3PR
On → PK turns on and returns to parking state.

Returning to the previous explanation, the restriction operation from the time when the parking switch 3P is switched will be explained.
When parking command relay PK is turned off by switching parking switch 3P, its contact
Auxiliary relay for parking command due to opening of PK ₁
PKX turns off. However, since diode D is connected to the coil part of relay PKX,
An off delay of about 30msec occurs. During this time, the contact
The circuit between PK ₂ and PKX ₁ is closed and the limit relay is activated.
OK turns on (the small relay only needs about 15 msec to close) and is self-maintained by closing the OK ₁ contact. On the other hand, the parking command relay PK is turned off due to the opening of contact OK ₂ , and the restriction relay is turned off.
While OK is on, park switch 1
No matter how P to 5P are switched, the parking command relay PK will not turn on, and the elevator will continue to be operable. However, when a resident on the third floor gets into the elevator and presses the car call button on the first floor to register a car call, the car call detection relay turns on, its contact CY ₁ closes, and the elevator goes to the first floor. When you start driving toward the target, the driving detection relay turns on and its contact OP ₃ closes, and contact OK ₃ is closed, so
Car call operation detection relay CH turns on and its contacts
Self-maintained by CH ₁ closed circuit. When relay CH turns on, its contact CH ₂ opens, but the contact
Since OP ₁ is closed, the limit relay OK remains on.

When the vehicle reaches the first floor, the in-operation detection relay is turned off and its contacts OP ₁ and OP ₃ are opened. As a result, the limit relay OK is turned off, and the car call operation detection relay CH is also turned off due to the opening of the contact OK ₃ . Further, when the limit relay OK is turned off, its contact OK ₂ is closed, and by operating the parking switch thereafter, the parking state can be entered at any time.

Next, the operation when the parking switch 3P is switched and the elevator is not used will be explained. As explained above, when the parking switch 3P is switched on, the limit relay OK is turned on and self-maintained, which causes its contact OK ₅ to close and the timer T to start counting. The setting time of timer T is approximately 1 minute, and if neither a landing call nor a car call is registered within this setting time, neither the landing call detection relay nor the car call detection relay will turn on, and contact CY ₁ will open. The car call operation detection relay CH does not turn on, but eventually the timer T turns on, its contact _T2 opens, and the limit relay OK turns off, and as above,
If you operate the parking switch from now on, you can shift to the parking state at any time. That is, the restriction of the parking command is released.

The operation has been explained above by way of example, but even if the parking switch on any floor is operated, the state can be shifted to the opposite state from the state before the operation.

As described above, according to the embodiment of the present invention, the operating and resting states of the elevator can be freely switched by operating any of the parking switches 11P to 5P provided on each floor, and the operation can be resumed. In such a case, there is no need to worry about the elevator being suspended until the elevator stops operating or a predetermined period of time has passed, making it easier to use the elevator.
It has the advantage of being excellent in crime prevention.

In the embodiment shown in Fig. 3, the circuit uses a relay, but in an elevator equipped with a microcomputer, the operation of these circuits may be performed by the microcomputer, and the same effect can be obtained. be able to.

〔Effect of the invention〕

As explained above, according to the present invention, the elevator can be operated and stopped from any floor, and when the elevator is restarted, the elevator is operated until it is stopped or a predetermined time has elapsed. teeth,
Since there is no need to worry about the elevator being shut down, it is easier to use the elevator, and it also has the effect of providing excellent crime prevention.
