Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for a rust remover that selectively polishes and cleans rust spots scattered on a ship's outer plate, for example. The rust removal process can be performed simply by reading the information into a microcomputer using a light pen, thereby improving usability and workability.

Conventionally, with a rust remover equipped with multiple projection heads that project abrasive material onto a wall surface to form a cleaning pattern, when cleaning rust spots scattered on a wall surface, the rust remover is At the same time, the abrasive supply valve of each projection head is individually opened and closed by hand, and the abrasive is supplied only to the projection head corresponding to the rusted part to perform rust removal operation.

However, with this type of conventional method, it is necessary for humans to visually inspect the wall surface, operate the supply valve frequently, and control the operation of each projection head, resulting in mental strain and fatigue. It has the disadvantage of extremely poor usability and workability.

This invention was made with the above points in mind,
Next, the present invention will be explained in detail with reference to drawings showing one embodiment thereof.

In the drawings, 1 is a wall surface such as a hull outer panel, 2 is a rusted part scattered on the wall surface 1, 3 is a running trolley that moves to the right along the wall surface 1, and 4 is a supporting leg 5 on the upper surface of the running trolley 3. The rust remover is supported by a rust remover, and includes four centrifugal projection heads 6 arranged in series in the vertical direction, a motor T for rotationally driving each of the projection heads 6, and an abrasive supply tank 8. , a supply pipe 9 that guides the abrasive material in the supply tank 8 to each projection head 6 , and an abrasive material supply valve consisting of a solenoid valve or the like interposed in each branch pipe of the supply pipe 9 to the projection head 6 . 10, an abrasive material recovery tank 11, and a circulation device 12 that returns the abrasive material in the collection tank 11 to the supply tank 8, and projects the abrasive material from each projection head 6 onto the wall surface 1 in the vertical direction. A vertical polishing pattern is formed to polish and clean the rusted portion 2.

A video camera 13 is supported on the traveling carriage 3 via a support leg 14 and is installed forward in the direction of movement of the rust remover 4, that is, on the right side, and takes images of the planned movement positions of each projection head 6 on the wall surface 1.

Reference numeral 15 indicates an operation console provided on the traveling trolley 3, and reference numeral 16 indicates a microcomputer (hereinafter referred to as microcomputer) on the operation console 15.
, 17 is a color CRT as a peripheral device for the microcomputer 16.
The video signal from the video camera 13 is projected onto the fluorescent surface of the CRT 17.

18 is the coordinates on the screen of CRT17, and the microcomputer 16
By pressing the rusted part 2' on the wall surface projected on the CRT17 with the light ben 18, the coordinates of the rusted part 2' on the screen are read into the microcomputer 16 and stored. .

Reference numeral 19 indicates an output driver that individually controls the opening and closing of the supply valve 10 of each projection head 6 based on the control output from the microcomputer 16, 20 indicates a cleaning pattern formed on the wall surface 1, and 21 indicates the video camera 13 on the wall surface 1. This is the imaging surface.

Note that the coordinates on the screen of the CRT 17 are divided into four stages according to the rust removal width of each projection head 6, and each stage is divided horizontally in units of a certain rust removal area.
By pressing the rust removal section of the light ben 18, the corresponding rust removal section is displayed on the screen, making it easy to give rust removal instructions on the screen of the CRT 17.

Further, the moving speed of the traveling trolley 3 and the distance between the rust remover 4 and the video camera 13 are inputted in advance to the microcomputer 16, and the coordinate position of the rusted part 2' on the screen of the CRTl7 indicated by the light bevel 18 is inputted in advance. The microcomputer 16 is programmed to control the supply valve 10 in accordance with the time the rust remover 4 passes. Next, the operation of the embodiment will be explained. First, the traveling cart 3 is moved along the wall surface 1 at a predetermined constant speed, and a video signal from the video camera 13 is continuously displayed on the CRT 17.
Here, it is necessary to adjust the brightness and contrast of the image on the CRT 17 so that the coordinate position can be read by the light ben 18. Then, the worker monitors the rusted part of the wall while watching the screen that flows from right to left on the CRT17 starboard, and when the rusted part 2 is displayed, moves the rusted part 2' on the screen to the light spot. 18 and enter the coordinates into the microcomputer 16. The microcomputer 16 stores information on this coordinate position in its memory, processes the information on the coordinate position, and selects the rusted part 2 on the wall surface 1 corresponding to the rusted part 2' on the screen indicated by the light ben 18. A control signal is output to the output driver 19 in accordance with the time when the rust remover 4 passes, and only the abrasive supply valve 10 of the projection head 6 corresponding to the rust forming part 2 is opened, and the rust forming part 2 is cleaned. be done. Therefore, when operating a plurality of projection heads 6 individually,
In order to directly open and close each of the abrasive material supply valves 10 by manual operation, agile operations are required, but according to the embodiment described above, the operator can ' All you need to do is press the keys one after another with the light ben 18, and the microcomputer 16 then reads and memorizes the screen coordinates of the CRTl7 instructed by the light ben 18, and then removes the rust from the memorized coordinate position of the rusted part 2'. Since the projection head 6 of the machine 4 is activated to remove rust when it passes, the rusted part 2 can be automatically removed, eliminating the need for quick reflexes and reducing mental tension and fatigue. It can be easily operated by anyone without any complication, and usability and workability can be greatly improved.

In the above description, the microcomputer 16 and CRT are mounted on the traveling trolley 3.
Although an example is shown in which the 17 is mounted on a tower, only the rust remover 4 and the video camera 13 may be mounted on the trolley 3, and the others may be installed, for example, in a monitoring room and controlled remotely.

As described above, according to the rust remover control device of the present invention,
A rust remover equipped with multiple projection heads is run along the wall surface, and the video signal from a video camera located in the direction of travel of the rust remover is displayed on a CRT, and the rust on the wall surface is displayed on the CRT. The screen coordinates of the rusted area are read into a microcomputer using a light ben, and when the rust remover reaches the rusted area, the microcomputer supplies the abrasive material to the projection head corresponding to the rusted area and removes the rusted area. By cleaning the rust remover, the worker only needs to use the light ben to press the rusted part of the wall that is displayed on the CRT, and the rest is automatically removed by the microcomputer's controls and legs. It is much easier to use and can greatly improve usability and workability.
