转台

All the actuators of the three-axis turntable are brushless torque motors, all the bearings are aerostatic air bearings, so the friction caused by these elements can be neglected. The main source of friction is the metal-to-metal friction on the slip rings. Hence the "Columb+Viscous+Static" friction model is used here for analysis.

由于三轴转台的驱动系统选用的是无刷电机，轴承则采用的是气浮轴承，轴系上的摩擦力已大大降低，三轴转台上的摩擦主要是滑环轴上金属对金属的摩擦，所以文中选用&库仑＋粘滞＋静摩擦&的摩擦模型来进行分析。

Labeling process is in line with the COTS and squeege formed the COTS guaranteed cutan, when the charts after gelatinize cots and when you turn the subject box of the front end to scroll in the form of stick out a label; with a label of panels continue to campaign,张合 by 揭标-揭标 e-?·|-clamping of the label side margin was off, when the then standard barrel go to one side of the bearing bottle turntable with Mark intracavernous when the aluminum foil on the bottle labels; at the same time the label of the bottle with the cap bottles go taiqian line also with the pallet for the 90-degree rotation, across the brushlelss label group label is brushlelss; the last high school marching to starred on the head part of applanation.

贴标过程是胶辊和刮板配合使胶辊上形成一定厚度的胶膜，当标板经过胶辊时涂胶并在转过标盒前端时以滚动形式粘取出一张标签；带着标签的标板继续运动，由揭标筒的张合揭标指夹住标签侧缘而被揭下来，当接标筒转到承瓶转台一侧时通过压标海绵将铝箔标贴到瓶口上身标同时贴上）；贴了标签的瓶子随承瓶转台前行的同时还会随托盘作90度旋转，穿过刷标组时标签被刷平；最后行进到压标星轮上将盖顶部分压平。
