Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention, in general shipbuilding steel sketch material is used, those dimensions, the steel plate grade, and surface treatment relates to vary steel plate surface treatment apparatus.

[0002]

2. Description of the Related Art In Japanese shipyards, mild steel, high tensile steel 32, high tensile steel 36,
Many types such as high-tensile steel 40, stainless clad steel, and stainless steel have come to be used, and there are many cases where a plurality of types are used at the same time, and it is common to use sketch materials with different plate dimensions. Yes, the steel plate grade of each member cannot be distinguished when the members are cut out from the steel plate, so it is common to distinguish the steel plate grade by the color coding of the coating. A lot of storage space was required, and the steel plate grade and color were controlled by human judgment.

Regarding the conventional general steel plate surface treatment, FIG.
To explain, steel plates ST transported by truck T or ship S are piled up in storage area A, and further, one by one according to the delivery date.
A, b, c, d and MS, HT32, HT36 are sorted and piled up in a matrix according to the steel plate grade, and one steel plate ST is loaded one by one according to the date of delivery and the steel material grade.
Blasting device 2, coating device 3 and rear transfer device
The transportation process was sequentially performed with 4, and it was moved from the rear transportation device 4 to the steel plate storage area 5.

Referring to FIG. 2, the coating device of the steel plate surface treatment device is described. The steel plate ST to be treated is conveyed on the horizontal roller f2 inside the coating device case f1, and the coating spray gun f4 installed vertically is in the traveling direction. Chain f5 operating horizontally at right angles to
When the steel plate ST approaches, the proximity switch f6 senses and the contact turns on (ON), the paint is pumped from the paint tank f7 to the paint pump f8 via the pipe f9, and manual control of single-sided and double-sided coating is performed. Selection is made on panel f11, and paint spray gun f4 is turned on by controlling paint regulator f10 on.
When the paint was supplied to the steel plate ST and the proximity switch was turned off (OFF), the paint regulator f10 was turned off (OFF) and the supply of the paint to the coating spray gun f4 was stopped.

In order to change the color of the coating device according to the steel plate grade, the operation of the steel plate surface treatment device is stopped, and cleaning is performed from the paint tank f7 to the paint pressure pump f8, the pipe f9, the paint regulator f10 and the paint spray gun f4. The paint was changed and the painting was done.

As described in the prior art, the steel plates loaded into the steel plate yard are stacked in a matrix according to the loading date and the steel plate grade. The greater the variety of grades, the more labor, time, and space required for sorting.Therefore, every time the steel sheet surface treatment is color-coded according to the steel sheet grade, it is necessary to clean the coating equipment, treat the remaining paint, and stop the steel sheet surface treatment equipment. These have the problems that the operating time is increased and the coating process requires much labor and cost.

The present invention focuses on the above conventional problems,
Having the steel plate data on the date of import as a database on a computer, the steel plates are randomly carried into the steel plate surface treatment device, and the blasting process and the color change of the coating corresponding to the steel plate grade are carried out from the plate number obtained from the plate number input device. By automatically performing the treatment, it is possible to reduce the place where the steel sheets are stacked and the sorting work time, and to save labor in the surface treatment of the steel sheets. In the method of distinguishing by the coating color of the steel plate, if the coating color is wrong, it may develop into a serious problem. But,
In optical reading, which is considered as a plate number input device, there is a risk that the plate number on the steel plate will be difficult to determine due to dirt or the like during transportation and may be input as a different number. In addition, even if it is visually read, there is a possibility that a key input is made by mistake. In this case, by collating the actual measurement data of the steel plate with the plate size measuring device and the plate size data from the plate number obtained from the plate number input device,
An object of the present invention is to provide a safe steel plate surface treatment device by identifying a steel plate.
