Movement control method, movement manipulation apparatus, and method for manipulating movement of moving body

Abstract

In a movement control apparatus manipulation can be carried out while watching the movement of the moving body, without needing to watch one's hands, so even a novice operator can perform the manipulation easily, safely, reliably, and quickly. The apparatus can include a signal transmission cable, a casing of a manipulation remote controller disposed at one end of the cable, a rotary encoder that produces a signal corresponding to the direction of the casing, and a motor drive control circuit that is disposed on the other side of the cable and controls the movement of a moving body on the basis of a signal corresponding to the direction of the casing. The signal corresponding to the direction of the casing can be supplied from the rotary encoder, through the cable, to the motor drive control circuit. Therefore, the operator can hold down a manipulation switch without looking at his hands and thereby adjust the direction of the casing of the manipulation remote controller while looking at the movement direction of a load.

Description

TECHNICAL FIELD[0001]The presently disclosed subject matter relates to a technique for manipulating the movement of a moving body, and more particularly relates to a movement control method, movement manipulation apparatus, movement manipulation method, and so forth, with which the movement of a moving body can be manipulated easily, safely, reliably, and quickly, even by a novice operator.[0002]Definitions and interpretations of the terms used in the presently disclosed subject matter are listed below.[0003](1) “Remote” is an abbreviation for a remote controller in the sense of an apparatus for remote manipulating, remote controlling, or other such manipulations, or an abbreviation for a remote control in the sense of an apparatus for remote manipulate, remote controlling, or other such manipulations. A difference in signal transmission method (wireless versed wired) does not affect the definition or interpretation of “remote” unless otherwise specified.[0004](2) Unless otherwise s...

Benefits of technology

[0164]As a result, the moving body is monitored while the manipulation switch for the direction in which the moving body is to be moved is pressed from among the four manipulation switches provided to the side faces of the remote casing, and when the direction in which the moving body is to be moved is oblique with respect to the cuboid remote casing, the moving body is moved in a zigzag pattern within the horizontal plane by alternately pressing two manipulation switches, allowing the operator to move the moving body to the desired location without taking his eye off the moving body. The moving body can be lowered to the desired location by operating the up and down switch on the remote casing and lowering

Problems solved by technology

Such overhead cranes are conventionally manipulated by successively pressing the six buttons (east, west, north, south, up, and down) on a wired remote apparatus hanging down from the winder, but when the load is large, there is the possibility that the load hanging from the winder will come into contact with the person manipulating the wired remote apparatus hanging down form the winder, which poses safety problems.

However, with a wired type of remote apparatus, putting aside wireless types for the moment, when used for an overhead crane or the like that is used in a painting plant or the like, the push buttons on the remote apparatus can become soiled by paint and so forth, making it difficult to read the words (east, west, north, south, up, and down) written on the buttons, and since the operator is typically looking at the remote apparatus while pressing the buttons and manipulating the apparatus, he cannot watch the movement of the load being conveyed by the overhead crane, which not only makes it difficult to perform the work quickly and reliably, but also poses the risk that the operator of the remote apparatus may not notice if the load gets too close.

Furthermore, if the operator is a novice, he will not instantly be able to tell which way is east, west, north, or south, so a problem is that the work cannot be performed quickly and reliably.

Also, These problems are not unique to three-dimensional movement apparatus, and also occur with other types of movement apparat
