Description

The present invention relates to a moving operation method, a moving direction display device, and a moving operation system of an overhead crane device that suspends and moves a transported object in a factory or the like.

Conventionally, as a crane used indoors, an overhead crane having a girder erected on a pair of rails and running on the rails and a trolley moving on the girders in a direction facing the rails has been known. It is the main means of transportation in factories where rails are suspended and moved (see, for example, Patent Document 1).

In the overhead crane device, a hanger such as a hook suspended by a wire is connected to the trolley, and after the hanger is moved to a position above the object to be suspended by the traveling motion of the girder and the traversing motion of the trolley, the wire It is moved downward by winding down to attach a hanging tool to the hanging object. The hanging tool to which the hanging object is attached is moved upward by winding the wire, and is conveyed to a predetermined place by the traveling motion of the girder and the traversing motion of the trolley.

Then, in this type of overhead crane device, the operator specifies the moving direction by operating the pendant switch type wired type controller in which the cable is hung from the trolley or the wireless type controller without the cable from the ground, and remotely. It is designed to be operated.

When carrying out the work of transporting the transported object using this overhead crane device, the operator is located below the trolley while operating the controller, and the work of transporting the transported object while moving together with the movement of the trolley. There were many situations where we did.

Further, in general, the operation unit of the controller often displays the moving direction in the north, south, east, and west, and also in the factory, the display indicating the direction in the factory, for example, the lower surface of the overhead crane device or the wall surface of the factory. The north, south, east, and west are displayed on the screen, and the operator looked at this display, confirmed the moving direction of the transported object, and operated the controller.

However, as disclosed in Patent Document 1, in the case of the transportation work using the overhead crane device, the transported object is usually located at a higher place than the worker, and the worker's line of sight is always upward. On the other hand, since the controller is held by the operator and is usually operated near the front of the upper body of the operator, the operator faces downward when operating the controller and immediately upwards immediately after the operation. It was necessary to confirm the moving direction of the device or the transported object one by one, and this confirmation work was troublesome for the operator.

Therefore, in the disclosed technology of Patent Document 1, in a moving direction display device used in combination with a transport device in which a worker operates a moving body by using a controller to transport a transported object, a walking surface of the worker such as a floor surface or the ground is used. An irradiation unit that irradiates light rays is provided on the base portion of the moving body, and when the worker operates the controller to move the moving body in a desired direction, the walking surface of the worker such as the floor or the ground. A directional display indicating the moving direction of the moving body is formed.

Japanese Unexamined Patent Publication No. 2011-116560

By the way, in the current operation of the overhead crane by the ground pendant controller, the crane moves against the intention of the operator's moving direction, and the transported object collides with or is pinched by the installation object or the worker in the factory. It may lead to a disaster, especially when the crane starts to move. The reason for this is that the crane movement direction is generally displayed on the north, south, east, and west, and is displayed on the underside of the crane girder, so it is very difficult to confirm, and the operation is based solely on experience.

In the technique disclosed in Patent Document 1, the irradiation portion provided on the base portion of the moving body irradiates the walking surface of the worker such as the floor surface or the ground with light rays to walk the worker such as the floor surface or the ground. By forming a direction instruction display indicating the moving direction of the moving body on the surface, the operator operates while looking at the controller without being affected by the surrounding environment such as noise in the factory, and is positioned one by one after the operation. The moving direction of the moving body can be easily recognized without visually recognizing the moving body or the transported object, but when the worker operates the controller, the walking surface of the worker such as the floor or the ground Since the direction instruction display indicating the moving direction of the moving body is formed, the crane makes an initial movement when the controller is operated, and even if the operator recognizes the erroneous operation and immediately stops the operation. Since the suspended load moves, there is a problem that it is difficult to prevent a disaster such as a transported object colliding with an installation object or a worker in the factory or being pinched.

An object of the present invention is to irradiate a position (floor surface, etc.) visible to the operator in the direction in which the crane moves in view of the conventional circumstances as described above, so that the operator does not perform an operation contrary to the intention.

Therefore, the operator 30 of the overhead crane device 10 recognizes the moving direction of the overhead crane device 10 by the constantly displayed image I ( _IN , _IS , _IE , I _{W), and displays the image on the ceiling.} By selecting the operation unit of the controller 20 associated with the moving direction of the crane device 10, the moving direction of the overhead crane device 10 can be reliably instructed, and the operator 30 of the overhead crane device 10 can perform an operation contrary to the intention. You can avoid it.

The image display that associates the moving direction of the overhead crane device 10 with the operation buttons 21 _N , 21 _S , 21 _E , and 21 _W of the operation unit of the controller 20 is, for example, the operation buttons 21 _{N of the operation unit of the controller 20.} , 21 _S , 21 _E , 21 _W , and / or the display form of the image display by the moving direction display device 40 is linked to the selection operation of the operation button of the controller 20 by the operator 30, for example, a high-luminance display state.
