| 摘要 | PURPOSE:To correctly a perform parallel positioning of a movable pallet travelling path by elastically supporting a bevel gear axially on a common rotary shaft of a space adjust mechanism, in a free flow conveyer having a fixed pallet travelling path and the movable pallet travelling path disposed parallel thereto in such a manner that a space between both paths can be adjusted. CONSTITUTION:In a free flow conveyer, a feed screw 16 is rotated by rotation of a hundle 48, and a feed screw 24 and a reversely threading feed screw 28 are rotated through bevel gears 32, 42, a common rotary shaft 40 and bevel gears 34, 44, 36, 46, thereby adjusting a movable pallet travelling path 12 to be close and separate to and from a fixed pallet travelling path 10. In this case, the bevel gears 44, 46 mounted on both ends of the common rotary shaft 40 are disposed in such a manner as to axially retreat against a compression spring 46, so that the engagement of corresponding bevel gears 34, 36 can be released. In such disengaging condition, the feed screws 24, 28 are rotated independently to adjust the degree of parallel between both travelling paths 10, 12. | ||||||
