重力式货架说明_重力式货架工作原理

重力式货架说明由刀豆文库小编整理，希望给你工作、学习、生活带来方便，猜你可能喜欢“重力式货架工作原理”。

重力式货架：

重力式货架利用一边巷道作为存放，一边巷道作为取出，滚筒线按一定角度倾斜固定在货架横梁上，托盘从高端放入，沿滚筒线靠本身重力下滑，为控制托盘以稳定速度下滑，避免撞击，在滚筒线上每隔一定距离设置一套阻尼系统，托盘下滑速度越快，阻尼系统产生的阻力越大。端部分离机构设置在低端，用来分离最低端相临的两个托盘，这样最低端托盘就可以顺利地取出。重力式货架对托盘的要求较高，目前木制托盘的使用已经比较成熟，其他材质托盘需要提供实际使用的托盘做阻尼实验。重力式货架的空间利用率高于压入式货架及贯通式货架，而且真正实现了“先进先出”的原则，安全性及运转效率都与货位式货架相同，储存的密度很好，但成本较高，适合少样多量高频度的应用。

适用大量存放且要短时间出货之货品。适合ABC分类中的B级商品。适合先进先出。采用密集流道储存叠栈物，空间使用率可达85%。使用一般叉车存取。高度受限，一般在6米以下。每一流道一般只存放一种货品。建造费用较高、施工较慢。

Live racking

Working on a first-in, first-out basis, live racking provides extremely high levels of storage density in a given area.Pallets are loaded onto dedicated lanes of inclined gravity rollers which are set at a fixed gradient.When a load is taken from the picking face, the next rolls into position, with replenishment stock loaded at the opposite(upper)end of the lane.Stock rotation is therefore automatic with the minimum of forklift truck movements.Working on a first-in, first-out basis, live racking provides extremely high levels of storage density in a given area.Pallets are loaded onto dedicated lanes of inclined gravity rollers which are set at a fixed gradient.When a load is taken from the picking face, the next rolls into position, with replenishment stock loaded at the opposite(upper)end of the lane.Stock rotation is therefore automatic with the minimum of forklift truck movements.
