Document Type and Number:
WIPO Patent Application WO/2007/111053
Kind Code:
A1
Abstract:
A cutting machine secures safety of a worker against movement of a head without lowering production efficiency. When moving a cutting head (24) without cutting a cut material on a table (12), a moving truck (18) and the cutting head (24) are moved at a higher speed as compared with a case where the cutting head (24) is moved for cutting a cut material. If a worker exists on the table (12) and intercepts any one of light beams (30, 44) located in front and rear of a transom (20) when the moving truck (18) and the cutting head (24) are moving at a high speed, the moving speed is decelerated to a safe low speed but cutting work of the cut material is not interrupted. Subsequently, when the worker approaches the transom (20) furthermore and touches a wire (38) or a bar (50) in the vicinity of the transom (20), movement of the moving truck (18) and the cutting head (24) is stopped forcibly to interrupt cutting work.
