PROBLEM TO BE SOLVED: To prevent the occurrence of a time lag between the lift operations of left- and right-side lift driving sections by making the number and numbers of teeth of the lift rotation transmission gears of the left-side lift driving section equal to those of the right-side lift driving section. SOLUTION: When a work 21 placed on a loading conveyor 19 is transferred to a preliminary cleaning both 22 by means of an interlocked arm 13 for delivering work, a left-side transfer lift driving section 1 transmits the rotation of a lift driving motor 2 to an lift driving screw 3 and a nut 4 through transmission gears A and B. In addition, a right-side transfer lift driving section 20 transmits the rotation of a spline shaft 6 directly coupled with the motor 2 to a feed screw 3 and a nut 4 through transmission gears C and D. Therefore, the left- and right-side transfer lift driving sections 1 and 20 can be moved upward and downward by the same distance at the same speed. |
