Stereoscopic library The manufacturer introduces the development of gravity shelf
With the continuous development and maturity of the shelf industry technology in China, the gravity shelf has begun to be used in domestic warehouses. Although the construction cost of the gravity shelf warehouse is relatively high, and the application rate of the gravity shelf warehouse in China's small and medium-sized enterprise warehouses is not very high, its development prospects are good, and the future demand will be growing.
The gravity shelf is designed with a roller seat, which is properly tilted, and driven by the self weight of the goods. The pallets are intensively stored and in a good physical cycle to achieve the logistics effect of first in first out. An intensive storage warehouse system can make full use of the warehouse area, and the utilization rate of the warehouse area is about 30% higher than that of the general fixed shelf warehouse. The four basic principles of shelf design are:
Moderate ramp length
The total depth design of the shelf (i.e. the length of the guide rail) should not be too large, otherwise the unusable "dead corners" of the upper and lower parts will be large, affecting the use of space, and the ramp is too long, the controllability of the slide will be poor, and the impact of the slide will be large, which will easily cause unsmooth slide, blocking, and overturning of pallet goods.
Reasonable slope
After the slide is installed on the shelf, it should be ensured that it has a certain slope, so that the tray can slide under the action of gravity. If the slope of the sliding surface is too small, the tray will not slide or slide smoothly; If the slope is too large and the tray slides too fast, it will cause impact or overturn.
In addition, the gradient also depends on the material of the bottom of the tray. For wooden trays, 3.5%~3.0% can be taken; For plastic tray, 2.5%~2.0% can be taken; 2.0%~1.5% can be taken for steel tray. In the actual warehouse design, the Z best choice of slope shall be determined after detailed calculation and experiment.
Add damping device
In order to make the slide smooth, if the ramp is long, in order to prevent the pallet cargo from tipping due to excessive impact when it slides to the bottom of Z, a buffer device and a cargo taking separator should be set at the bottom of Z ramp, so it is difficult to design, manufacture and install, and the cost is high.
The shelf should not be too high
No matter what kind of shelf type warehouse, reliability and operability are particularly important. Gravity shelves are generally within 6 meters, and the weight of single pallet cargo is generally within 1000 kg. If the height is too high and the single pallet cargo is too heavy, its reliability and operability will be greatly reduced.
