<p>PROBLEM TO BE SOLVED: To automatically perform early fire fighting when a fire starts in a filter to a dust collector. SOLUTION: Dust generated when a workpiece W mounted on a working table 5 of a sheeting machine is worked is sucked into a body 31 of a dust collector together with an air current through a dust collecting dust 19. The sucked dust is stuck to a filter 37 in the dust collector body 31, and the clean air current which has passed through the filter 37 is discharged outside the dust collector body 31. The filter 37 is made a cylindrical body. In the upper part of the filter 37, an extinguishant area 53a where an extinguishant is sealed to be stored in advance within a belt-shaped area having a width in the height direction of the filter 37 is installed. In the middle part of the height direction of the filter 37, an extinguishant area 53b is similarly installed. When dust stuck on the filter 37 ignites to cause a fire, the filter 37 is broken and the extinguishant in the extinguishant areas 53a, 53b falls to perform incipient fire fighting to the firing site.</p> |
