    • PROBLEM TO BE SOLVED: To avoid collision between respective tooth tops of a rack gear and a pinion gear due to a phase shift between the rack gear and the pinion gear with a simple mechanism and to mesh the rack gear and the pinion gear smoothly.SOLUTION: A rack and pinion mechanism includes a rack gear 16 fixed to a stage 20 moving on a carrying track 7 while loading a carried object thereon and a plurality of pinion gears 17 connected to a drive source 13. At least two of the pinion gears are synchronized and rotate to mesh with the rack gear in sequence, whereby the rack gear is delivered from the pinion gear in the current process to the pinion gear in the subsequent process. The rack and pinion mechanism includes detection means that detects a phase difference of the pinion gear and a controller 25 which has a storage part 27, storing the detected phase difference, and controls the phase difference of the pinion gear in the subsequent process based on the phase difference of the pinion gear in the current process.
    • 要解决的问题:为了避免由齿轮和小齿轮之间的相移引起的齿条齿轮和齿轮齿轮之间的碰撞,并且能够平稳地啮合齿条和小齿轮。 :齿条齿轮机构包括固定在载物轨道7上的载物轨道7上移动的载物轨道7上的齿条16,以及连接到驱动源13的多个小齿轮17。至少两个小齿轮是 同步并旋转以便与齿条啮合,从而齿轮齿轮在当前过程中从小齿轮传递到小齿轮。 齿条齿轮机构包括检测小齿轮的相位差的检测装置和具有存储检测出的相位差的存储部27的控制器25,并且在后续处理中基于小齿轮的相位差来控制小齿轮的相位差 当前工艺中小齿轮的相位差。
