Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a marking work for drawing a welding line, a cutting line or a bending position indicating line on a steel plate member such as a bridge, and a coating film on the surface of the steel plate member as a pretreatment for the marking work. The present invention relates to a coating film removing device with a marking mechanism, which is capable of performing the coating film removal for removing

[0002]

2. Description of the Related Art The surface of a painted steel plate member is usually coated with a coating film such as a primer for rust prevention. Before the marking work for drawing a welding line, a cutting line or a bending position indicating line on the coated steel plate member, the work for removing the coating film must be carried out.

Conventionally, as an apparatus for removing the coating film on the surface of the coated steel plate member, an endless grinding belt for grinding the coating film on the surface of the coated steel plate member is brought into contact with and the sliding belt is slid to remove the coating film. A hand-operated coating film removing device for removing the film is known. Further, as a method for drawing an indicator line on the surface of the steel plate member after removing the coating film, a manual scribing method using black ink (white paint) or thread on the surface of the steel plate member is known. .

Conventionally, the work of removing the coating film on the surface of a coated steel sheet and then drawing an indicator line is generally carried out using the above-mentioned devices as follows. First, on the base,
A marking machine is run on the plate to draw an indicator line, and after this work the plate is moved to another location. Next, the hand-operated coating film removing device is run on the plate body to remove the coating film along the instruction line. And
The manual marking operation again draws the indicator line again on the plate body from which the coating film has been removed.

[0005]

However, when the coating film removing and marking operations are performed by each of the above-mentioned devices, the position with respect to the coated steel sheet is different because the coating film removing device and the marking device are separate devices. There is a problem that the precision of the indicator line drawn on the coated steel plate is incorrect,
Moreover, since the two operations are performed in different places, there is a problem that it takes time and labor to remove the coating film and perform the marking operation. Further, since the marking work is a manual work, a skilled technique is required to draw a constant indicator line.

The present invention has been made in view of the above-mentioned problems, and it is possible to remove a coating film on a coated steel sheet and then draw an indicator line therewith with high accuracy. It is also an object of the present invention to provide a coating film removing device with a marking mechanism that can reduce the labor and time required for marking work, and can draw a constant indicating line on a plate without skill. .

[0007]

In order to achieve the above object, a coating film removing device with a marking mechanism of the present invention has a base on which a plate having a coating film is mounted, and the base. An apparatus main body that is disposed on the base and is capable of traveling on the base, and a coating film of the plate body that is mounted on the apparatus main body and is rotationally driven by a drive source provided in the apparatus main body. And a marking mechanism that is mounted on the apparatus main body and draws an instruction line on the plate body from which the coating film has been removed by the grinding wheel.

Further, in the coating film removing apparatus with a marking mechanism of the present invention, a rail is laid on the base so as to extend in one direction, and the apparatus main body is movably arranged on the rail. A carriage is mounted on the main body of the apparatus so as to be movable in a direction orthogonal to the rails, and the main body of the apparatus, the grinding wheel, the marking mechanism, and a control unit for controlling driving of the carriage are provided. I am trying.

[0009]

According to the first aspect of the present invention, the apparatus main body can freely move on the base, and the grinding wheel mounted on the apparatus main body can freely move on the plate body placed on the base. Then, the coating film on the plate is removed. Then, a marking torch mounted on the main body and provided in the lateral direction of the grinding wheel performs marking.

According to the invention of claim 2, the apparatus main body is
The carriage mounted on the apparatus main body runs on a rail laid so as to extend in one direction on the base, and the carriage mounted on the apparatus main body moves in a direction orthogonal to the rails on the apparatus main body. The grinding wheel is driven to rotate,
The coating film is removed by abutting on the plate body placed on the base. After the removal of the coating film, the grinding wheel returns to the grinding start point. Then, the carriage moves in parallel,
The marking torch mounted on the carriage is
Marking is performed at a position where the coating is removed from the grinding wheel, which is located at the grinding start point. After the marking operation is completed, the marking torch returns to the grinding start point.
