Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator parking drive system.

[0002]

2. Description of the Related Art A conventional elevator parking operation apparatus is provided with a timer switch that operates in a predetermined time zone, as disclosed in Japanese Patent Laid-Open No. 61-243779, and the parking relay is provided with this timer. If the contact of the switch and the parking switch are connected in series and the parking switch is turned on to perform the parking operation, the contact of the timer switch is closed at a predetermined time and the parking operation is automatically performed. Pause on the floor.
Then, the contact of the timer switch opens when a predetermined time is reached, so that the parking operation is canceled and the car restarts operation.

[0003]

According to the above prior art, when the predetermined time when the parking operation is started, even if the user is still in the building, the parking operation is automatically performed. And the elevator stops. Therefore, there is a problem that the user in the building cannot use the elevator after that.

The present invention has been made in view of the above-mentioned drawbacks, and an object thereof is to provide a parking operation device for an elevator which can prevent deterioration of service for users in a building.

[0005]

In order to achieve the above object, the present invention is provided with an elevator car that operates a plurality of floors, and a timer switch that operates only for a predetermined time zone. The timer switch operates. At this time, in the elevator parking operation device that automatically suspends the car at a predetermined floor, it is provided with detection means for detecting that all the illumination lights provided on the floors of the plurality of floors have been turned off, and this detection means When the timer switch is activated and the timer switch is activated, a means for automatically performing a parking operation is provided.

[0006]

When the parking switch is turned on and the contacts of the timer switch are closed at a predetermined time, if all the floor lamps are turned off, the parking operation is immediately performed. When the illumination lamp is on, the parking relay is not energized, so the parking operation is not performed. In this way, since parking operation is performed only after there are no users in the building, it is possible to prevent service deterioration for users in the building.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an electrical connection diagram showing an embodiment of the present invention, and FIG. 2 is a sectional view of a hoistway.

In FIG. 2, 1 is a hoistway, 2 is a car, and 3 is a car.
1 to 39 are halls from the 1st to 9th floors, 41 to 49 are hall doors from the 1st to 9th floors, 51 to 59 are illumination lights provided at the halls 31 to 39, and 6 is provided at the 1st floor hall 31 It is a parking switch.

In FIG. 1, P and N are DC power supply terminals and 5
1b to 59b are normally-closed contacts of a contactor for turning on the illumination lamps 51 to 59, 10 is a relay for detecting that all the illumination lamps 51 to 59 are off, and 10a is a normally-closed contact,
Reference numeral 11 denotes a timer switch that performs a closing operation at a first predetermined time, for example, 10 o'clock in the evening, and the contact 11a closes, and when the second predetermined time, for example, 6 o'clock in the morning, opens, 12 is a parking switch. 12 relays to start driving
Reference numeral a is its normally open contact, and 13 is a parking circuit.

Next, the operation of this embodiment will be described.

Now, at about 8 o'clock in the evening, the parking switch 6 is turned on for the parking operation. At this time, night 1
Since it is not 0 o'clock, the timer switch 11 is not operating, and therefore the parking operation is not performed. 10 o'clock at night
That is, at the first predetermined time, the timer switch operates and the contact 11a closes. At this time, the halls 31 to 39
If the illumination lamps 51 to 59 are off, the contacts 51b to 5
Since 9b is closed, relay 10 is energized and contact 1
0a is closed, the relay 12 is energized by the circuit of P-6a-10a-11a-12-N, the contact 12a is closed, the parking operation is performed by the parking circuit 13, and the car 2 is returned to the first floor and stopped. To do. At the second predetermined time, that is, at 6:00 in the morning, the contact 11 of the timer switch 11
Since a is opened, the relay 12 is deenergized, the contact 12a is opened, the parking circuit is cut off, and the elevator returns to normal operation.

Next, the first predetermined time, that is, 10 at night
When it is time, there are users in the building again, for example, 9
When the floor lamp 59 is on, the contact 59b is open and the relay 10 is not energized. Therefore, since the relay 12 is also not energized, the parking operation is not performed, and the elevator is normally operated. After that, when all the users on the 9th floor exit and the illumination lamp 59 is turned off, parking operation is performed in the same manner as above.

As described above, when there is a user in the building, the circuit configuration is made such that the parking operation is invalid even during the parking operation, so that the service of the user can be prevented from being deteriorated.

It should be noted that the presence / absence of a user is determined by the lighting lamps 51 to 51 of the hall.
Although it was determined by turning on and off 59, an office lamp can be used. In addition, the illumination lights 51 to 5 of the hall
When it becomes difficult to get on the car 2 when 9 is turned off, the relay 12 may be replaced with a timer so that the parking operation is performed after a predetermined time.

[0016]

According to the present invention, it is determined that there is a user when the illumination lamp in the building is lit, and when this illumination lamp is lit, even when the parking operation is performed,
Since the parking operation is disabled, it is possible to prevent the service of the user from being deteriorated.
