Problems solved by technology

[0005] However, in the above-mentioned prior art, when the elevator car rises or descends, the end of the door-openable area of ​​the shielding member provided with the cutout and the shielding member without the cutout is detected by a photoelectric position detector, thereby The parking control of the elevator car is carried out. However, since the elevator has to travel a considerable distance from the detection of the end of the door-openable area to the actual parking process, the accuracy of the parking control varies, and high-precision parking control cannot be performed.

Abstract

PROBLEM TO BE SOLVED: To provide an apparatus for controlling an elevator car that can achieve CUMP and can perform landing control with high accuracy. SOLUTION: One shielding member 11 arranges a door zone detection area 34, a door zone upper end re-levelling zone lower end detection area 35 and a door zone lower end re-levelling zone upper end detection region 36. A photoelectric position detector 10 includes: a first detection unit 101A that detects the door zone lower end and door zone upper end of the door zone detection area 34; a second detection unit 102A that detects the re-levelling zone lower end and door zone upper end of the door zone upper end re-levelling zone lower end detection area 35; and a third detection unit 103A that detects the door zone lower end and the re-levelling zone upper end of the door zone lower end re-levelling zone upper end detection area 36.

Description

technical field [0001] The present invention relates to a control device for an elevator car using a shielding member provided near an elevator entrance and exit on each floor and a photoelectric position detector for detecting the position of the elevator car by detecting the shielding member . Background technique [0002] Depending on whether releveling control is performed, as the shielding member installed at the elevator entrance and exit of each floor, a shielding member with a cutout is used, or a shielding member with only a door-openable area (Door zone) is used. A shielding member provided with a cutout is composed of a door-openable area part and a re-alignment part. The size of the door-openable area part corresponds to the size of the door-openable area, and is used to detect the door-openable area. A vertical direction of the re-alignment part One side is set to the size required for re-alignment control (control for eliminating the height difference between ...
