重力式货架为横梁式货架密集排列组合后在横梁上设置有一定坡度的辊道,托盘单元货物从辊道高端进入,利用自身的重力下滑至辊道的低端。当出库端的第一个托盘货物取走后,后面的托盘单元货物在重力的作用下向出库端补位。为了防止托盘单元货物流速过快,在辊道上每隔一段距离设有阻尼装置,长距离的辊道两侧设有托盘导向防跑偏装置。出库端设有挡板和取货分隔机构,每一列距上可布置两个货位。重力式货架适合存放同类型,批量大,储存时间长的货物。重力式货架对托盘质量要求高,且单元托盘货物重量之间偏差不能过大,单元货物重量宜控制在1500kg之内。
Gravity racking is storage system with densely arranged pallet racking and a gradient roller table on the beam, in which goods in pallet enter the system from the higher end of the roller table and then slide to the lower end by virtue of gravity. After the first pallet at the output end is taken out, the subsequent pallets move to the output end by gravity. To prevent too high flow of the goods, damping devices are set on the roller table at certain interval. In the case of long roller table, pallet guiding devices are set on the two sides of the table. There are baffle plates and separating mechanism at the output end, and two goods locations can be arranged in each row pitch. Gravity racking is suitable for storage of the same type of goods with high quantity and long storage duration.Gravity racking has high requirements on pallet quality, and the weight difference between individual pallets should not be too great. It is recommended to control the weight of single pallet within 1,500kg.
