Robot, dust collection device, and dust collection method

Abstract

Disclosed herein area robot, a dust collection device, and a dust collection method. The robot includes a first moving mechanism, a second moving mechanism, a dust collection part, and a dust collection part moving mechanism. The first moving mechanism is disposed on a base body, and moves a workpiece to be cut in a first axis direction. The second moving mechanism is supported on the base body via support portions, and moves a cutting body in a second axis direction orthogonal to the first axis direction. The dust collection part is disposed to face the cutting body, and collects cutting chips generated by the cutting of the workpiece to be cut using the cutting body. The dust collection part moving mechanism moves the dust collection part between a first position close to the workpiece to be cut and a second position remote from the workpiece to be cut.

1 . A robot comprising:
 a first moving mechanism disposed on a base body and configured to move a workpiece to be cut in a first axis direction;   a second moving mechanism supported on the base body via support portions and configured to move a cutting body in a second axis direction orthogonal to the first axis direction;   a dust collection part disposed to face the cutting body and configured to collect cutting chips generated by cutting of the workpiece to be cut using the cutting body; and   a dust collection part moving mechanism configured to move the dust collection part between a first position close to the workpiece to be cut and a second position remote from the workpiece to be cut.   
     
     
         2 . The robot of  claim 1 , wherein
 the dust collection part moving mechanism moves the dust collection part to the first position upon the cutting of the workpiece to be cut using the cutting body.   
     
     
         3 . The robot of  claim 1 , wherein
 the dust collection part moving mechanism moves the dust collection part to the second position before or after the cutting of the workpiece to be cut using the cutting body.   
     
     
         4 . The robot of  claim 1 , wherein:
 The dust collection part is formed in a tubular shape having a direction orthogonal to each of the first and second axis directions as its tube axis direction;   a drive source configured to drive the cutting body is connected to the cutting body; and   when viewed in the tube axis direction, an area of an opening of the dust collection part is set to be smaller than that of the drive source and to be larger than that of the cutting body.   
     
     
         5 . The robot of  claim 1 , wherein
 the dust collection part moving mechanism is composed of an actuator connected to the dust collection part and configured to reciprocate the dust collection part in a third axis direction orthogonal to each of the first and second axis directions.   
     
     
         6 . The robot of  claim 5 , wherein
 the dust collection part is disposed below the cutting body in the third axis direction.   
     
     
         7 . The robot of  claim 1 , further comprising:
 a following structure configured to support the dust collection part moving mechanism and to place the dust collection part at a position facing the cutting body to follow movement of the cutting body relative to the workpiece to be cut.   
     
     
         8 . The robot of  claim 7 , wherein
 one end part of the following structure supports the dust collection part via the dust collection part moving mechanism, and a remaining end part of the following structure is mounted on the second moving mechanism.   
     
     
         9 . The robot of  claim 7 , wherein
 an intermediate part of the following structure is formed in a shape that bypasses the workpiece to be cut.   
     
     
         10 . A robot comprising:
 a first moving mechanism disposed on a base body and configured to move a workpiece to be cut in a first axis direction;   a second moving mechanism supported on the base body via support portions and configured to move a cutting body in a second axis direction orthogonal to the first axis direction;   a dust collection part disposed to face the cutting body and configured to collect cutting chips generated by cutting of the workpiece to be cut using the cutting body; and   a following structure configured to place the dust collection part at a position facing the cutting body to follow movement of the cutting body relative to the workpiece to be cut.   
     
     
         11 . A dust collection method comprising:
 moving a workpiece to be cut in a first axis direction;   moving a cutting body in a second axis direction orthogonal to the first axis direction;   cutting the workpiece to be cut with the cutting body;   
       disposing a dust collection part to face the cutting body, moving the dust collection part to a first position close to the workpiece to be cut, and collecting cutting chips generated by cutting; and
 moving the dust collection part to a second position remote from the workpiece to be cut. 
 
     
     
         12 . The dust collection method of  claim 11 , wherein
 collecting the cutting chips comprises placing the dust collection part at a position facing the cutting body to follow movement of the cutting body relative to the workpiece to be cut and collecting the cutting chips.
