Embodiment 1

[0031] figure 1 It is a figure which shows the structure of the control apparatus of the elevator concerning Example 1 in embodiment of this invention. figure 1 Among them, the control device 20 of the elevator 100 is constituted by a CPU (Central Processing Unit: Central Processing Unit). In this CPU, a box moving amount measurement unit 21, a correction possibility determination unit 22, a starting compensation torque correction unit 23, a hoisting motor control unit 24, a continuous correction times counting unit 25, and a mechanism adjustment request notification unit 26 are set by software. . The mechanism adjustment request notification section 26 is connected to the monitoring center 28 via a (public) telephone line 27 so that the mechanism adjustment request notification section 26 can communicate with the monitoring center 28 . For example, the CPU as the control device 20 sequentially reads the programs on the storage device, interprets them, and executes them, t...

Embodiment 2

[0048] Figure 7 It is a flowchart showing the processing procedure of the elevator control device according to the second embodiment. in addition, figure 1 The structure of the shown elevator 100 and the control device 20 of the elevator 100, Figure 2 to Figure 4 The relationship between the winch motor torque and the load in the box is shown, and Figure 5 The shown relationship between the ejection amount (reverse rotation amount) and the starting compensation torque correction value is the same as that of Embodiment 1, and therefore, repeated description is omitted. In addition, in Figure 7 In the process from step S1 to step S9 and Figure 6 The processes shown are the same, and therefore descriptions are appropriately omitted.

[0049] Figure 7 In, from step S1 to step S9, carry out and Figure 6 The same processing as in Example 1 is shown. Therefore, if the process is performed from step S1 to step S3, and it is determined in step S4 that there is pop-up, t...

Abstract

An elevator control device is capable of directly grasping a riding feel of a box body and accurately adjusting the torque of a lifting motor in a starting compensation process. Based on a load in the box body, the control device 20 of an elevator 100 utilizes the relation between the predetermined load in the box body and the torque of the lifting motor to obtain the torque of the lifting motor in the starting process, the torque of the lifting motor is corrected, and the lifting motor 4 is driven to maintain the good riding feel in the starting process, wherein the when the box body is started when the load in the box body is zero, the movement amount of the box body is measured according to the output of a speed limiter linked encoder 7 attached to a speed limiter 6 linked with the action of the box body 1, and when the movement amount of the box body exceeds a preset reference range, a starting compensation torque correction part 23 is utilized to correct the torque of the lifting motor in the starting process according to the movement amount of the box body.

Description

technical field [0001] The present invention relates to a control device for an elevator, and more specifically, to a control device for an elevator having a start compensation function of providing torque to a hoisting motor in advance before releasing a brake. Background technique [0002] In recent years, the elevator has a starting compensation function to obtain a better riding experience when starting, that is, it is equipped with a weighing device that detects the weight of the passenger in the box, and provides the hoisting motor with the weight detected by the weighing device. Torque, so that when the brake is released, the start is smoother, without the box popping out, or reversed. In addition, in the ride quality inspection performed during the periodical inspection, if the pop-up or inversion of the box is felt, the amount of starting compensation torque is adjusted to adjust the ride quality. At this time, ride comfort adjustment under no-load conditions is ge...
