Problems solved by technology

[0005] However, if the opening and closing operation of the door is repeated three times in this way, the passenger's so-called feeling of waiting becomes stronger, and there is a disadvantage in that the use efficiency of the elevator is reduced.

no. 1 Embodiment approach

[0036] First, the first embodiment will be described. figure 1 Among them, (a) shows a partial front view of the elevator lobby in this embodiment, and (b) shows a partial side cross-sectional view of the elevator lobby in this embodiment. figure 2 It is a block diagram explaining the main part of this embodiment. image 3 It is a flowchart used in this embodiment.

[0037] In the elevator 10 described in this embodiment, a pair of car doors 12a, 12b are provided in a horizontally slidable manner for the car of the elevator. Figure 4 ) is provided with a pair of hall doors (hall doors) 14a, 14b so as to be able to slide horizontally on the threshold. The pair of car doors 12a and 12b are connected so as to be slidable in opposite directions on the threshold via a car door opening and closing mechanism (not shown) provided in the car. In addition, the pair of hall doors 14a and 14b are connected so as to be slidable in opposite directions via a hall door opening and closin...

no. 2 Embodiment approach

[0051] Next, a second embodiment will be described. exist Figure 4 Among them, (a) shows a partial front view of the elevator lobby of the present embodiment, and (b) shows a partial side sectional view of the elevator lobby of the present embodiment.

[0052] In the elevator door control mechanism according to this embodiment, compared with the first embodiment, the wind speed sensor 42 for measuring the wind speed of the air flowing from the elevator hall F into the hoistway S is different from that of the first embodiment. The hall door 14a, 14b of the hall is on the threshold part RB on the inner side of the shaft S and is not toward the door pocket 17 (refer to figure 1 ) (that is, the entrance) protrudes, and is attached to the holding member 43 .

[0053] In this embodiment, the wind speed received by the wind speed sensor 42 increases as the door is closed, and the signal from the wind speed sensor 42 is sent to the control panel 28 via the base 32s and the cable (r...

no. 3 Embodiment approach

[0056] Next, a third embodiment will be described. Figure 5 It is a partial front view of the elevator lobby in this embodiment. Figure 6 Among them, (a) is a partial plan view showing the door sill of the elevator hall, and (b) is a partial side cross-sectional view viewed from the direction 6b-6b of (a).

[0057] In the elevator door control mechanism according to this embodiment, the wind speed sensor 52 for measuring the wind speed of the air flowing from the elevator hall F into the shaft S is arranged on the threshold of the elevator hall door. The bottom side of the trough RD for dust collection.

[0058] As an example, a through hole RH penetrating from the bottom of the groove RD in the vertical direction is formed in advance at a predetermined position of the sill R placed on the sill holder 51 (a component mounted on the car floor), and on the back side (lower side) of the sill R side) The holding member 53 (support fitting etc.) for holding the wind speed senso...

Abstract

The invention provides an elevator door control mechanism and an elevator door control method. The door control mechanism (20) of the elevator has: a wind speed sensor (22) for measuring the wind speed of the air flowing into the shaft from the elevator hall; The door control unit (26) that provides the drive force of the door operator motor (24) to open and close the hall door. The door control unit (26) controls the driving force of the door operator motor (24) according to the wind speed detected by the wind speed sensor (22), so as to increase the door closing force of the hall door of the elevator in stages or continuously.

Description

technical field [0001] Embodiments of the present invention relate to an elevator door control mechanism and an elevator door control method that control a door closing force of a hall door. Background technique [0002] The door closing force and door opening force of the hall door of the elevator are given by the driving force of the door machine motor. [0003] However, when the doors of the elevators on the floors connected to the outside are closed, an airflow flowing from the lobby side into the elevator hoistway is generated, and the doors cannot be closed and thus the lift of the car cannot be started. [0004] Therefore, in the past, when the door cannot be closed within a predetermined time due to air flow when closing the door, the door is opened again. If this action is repeated three times, the control circuit is switched to increase the driving force of the motor for opening and closing the door to increase the closing force. Regarding such a document, there i...
