<p>PURPOSE:To make it possible to secure a maintenance space by arranging a rotary arm capable of simultaneously transferring two works on neighboring two positions by rotating its rotary axis by a certain angle, with the rotary arm having two chuck sections for attaching/detaching works with its rotary axis on the center of the circumference. CONSTITUTION:Two chuck sections 35, 36 for attaching/detaching a work are provided on a rotary arm 37. As a result, a maintenance space can be easily secured by turning aside the chuck sections 35, 36 by rotating the rotary arm 37 in the case the chuck sections 35, 36, etc., are positioned in a position where the maintenance is to be performed. In this case, works W on positions P1 and P2 can be simultaneously transferred to positions P2 and P3 by rotating the rotary arm 37 by a certain angle. The work W finished with cleaning at the position P3 on the other hand is transferred at an appropriate timing during the cutting of a succeeding work W. As a result, there is no work standby time in a work cutting section where the work from the position P2 is loaded/ unloaded and therefore the efficiency of transfer remains unchanged as before.</p> |
