Definitions

  • the present invention relates to a marker for grinding and cleaning capable of forming a mark on the surface of an exposed base material of a workpiece while grinding and cleaning the workpiece covered with a coating to peel the coating therefrom.
  • oxidized iron is removed from a surface of the steel sheet to expose a base material thereof, rustproof coating is performed thereon, and a work such as cutting or welding is performed thereon in this state.
  • a cutting speed may be decreased during the cutting or a blowhole may be formed during the welding in accordance with constituents of rustproof paint, which may cause a welding defect or the like.
  • a rustproof coating is peeled along a desired cutting line or welding line to expose a surface of a workpiece, information such as a cutting line, a welding line, or a symbol of a member to be welded is marked on the exposed surface, and then cutting or welding is performed along the mark.
  • Patent Document 1 relates to a numerically-controlled grinding-cleaning device in which a grinding-cleaning carriage is loaded on a carriage, configured to travel in one direction, to be movable in the direction perpendicular to the traveling direction and the grinding-cleaning carriage is attached with a blaster nozzle and a marking torch or a printing device.
  • a work of peeling the paint coated on the surface of the steel sheet and a work of forming a mark or a print thereon may be separately performed. For this reason, the work of peeling the paint coated on the surface of the steel sheet is first performed. Then, after a series of peeling work is finished, the marking work may be performed on the exposed surface with the paint being peeled again by returning the grinding-cleaning carriage to the initial position.
  • the mark is formed on the exposed surface of the steel sheet. Then, when the cutting or the welding is performed along the mark, the cutting or the welding may be performed without the influence of the paint. For this reason, the cutting or the welding may be performed with high quality without decreasing the cutting speed or forming the blowhole at the welding portion.
  • Patent Document 2 relates to a numerically-controlled grinding-cleaning device which has the same basic configuration as that of Patent Document 1, but is different in that an endless grinding belt is used to grind and clean the steel sheet. For this reason, the structure of the grinding-cleaning device becomes complicated, but a function of peeling paint from a surface of a steel sheet or a function of forming a mark such as a line, a character, or a symbol on an exposed surface may be performed.
  • Patent Document 1 Japanese Patent No. 2875745

  • the grinding-cleaning member using the blaster nozzle or the grinding belt and the marking member such as the marking torch or the printing device are loaded on the same grinding-cleaning carriage while having a predetermined gap therebetween. Then, the grinding-cleaning work and the marking work may be separately performed on the steel sheet subjected to the rustproof coating. In this case, the grinding-cleaning work is performed once on the steel sheet to expose the surface of the steel sheet, and the marking work is performed on the exposed surface of the steel sheet. That is, the grinding-cleaning work and the marking work are performed by moving the grinding-cleaning device twice with respect to one steel sheet. For this reason, a problem arises in that it takes time for the marking work.
  • An object of the invention is to provide a marker for grinding and cleaning capable of shortening a work time by forming a mark on a workpiece at the same time when grinding and cleaning processes are performed on the workpiece.
