Shuttle racks are also known as crawler-type automatic guided vehicles. It has the characteristics of high speed, high reliability and low cost. Shuttle rack is an important equipment of three-dimensional warehouse, which automatically connects with other logistics equipment, such as storage platform and buffer station. Conveyors, elevators, robots, etc. according to the delivery plan.
The speed of shuttle truck determines the logistics efficiency of the whole shelf warehouse to a certain extent; the power supply mode and continuous walking ability of shuttle truck determine the difficulty of installation and construction of shelf warehouse; the intelligent level of shuttle shelf determines the difficulty of intelligence and design of shelf warehouse. Therefore, for shuttle shelf warehouse system, shuttle shelf itself is worth studying and improving.
According to the types of transport units, shuttles can be divided into pallet shuttles and box shuttles. According to different duty stations, shuttles can be divided into transport shuttles and shuttles. In terms of load and storage form, there are single-station single depth, single-station double depth, single-station multiple depth, double-station single depth, double-station double depth, double-station multiple depth, multi-station variable; but the most commonly used are single-station single depth and single-station double depth.
The important role of shuttle shelves is to solve two main problems. One is the problem of intensive storage. The use of shuttle system can greatly improve the storage density. This is a lot of technology, such as a dual-depth stack. The second is fast access. In fact, it is very popular at the moment. The fundamental reason of "goods to people" picking technology is that the use of multi-layer shuttle technology has thoroughly solved the problem of fast access. It can be said that the development of shuttle vehicle technology laid the foundation, pointed out the direction of future logistics technology development, and opened up a new world.
Compared with ordinary shelves, shuttle shelf system can greatly increase the area ratio of warehouse. For example, after converting general shelf goods into shuttle systems, the original warehouse can be used up to 30%. Of course, every project requires our engineers to make reasonable plans according to the specific situation.
It can make the whole shelf system more stable. Shuttle rack is converted into shuttle system, and the whole rack system is more stable through beam connection.
Improve the efficiency of cargo handling operations. Because the shuttle operation is more convenient than the forklift operation, the operator is easy to use and the work efficiency is improved.
If the rack driver is converted into a shuttle rack system, the original rack system can be used, which greatly reduces the cost of refitting. Because the overall structure of the two shelf systems is the same, the transformation is very simple. Simply connect the original shelf to the beam, place the shelf between the shelves, and then use shuttle truck to replace the original forklift.
Shuttle rack is set in the channel, each channel is a level of inventory channel, each channel has a track for shuttle truck operation, shuttle truck running back and forth in the tunnel, automatically entering and leaving goods, improve logistics efficiency, and shuttle truck can cooperate with stacker, automatic forklift or AGV, in different pillars. Automatic exchange between different layers and channels makes scheduling more flexible and automated.
1. High-density storage, high warehouse utilization.
2. High efficiency, greatly reducing the waiting time for work.
3. The operation mode is flexible, and the access mode of goods can be FIFO or FIFO.
4. High safety factor, reduce collision between shelf and forklift, improve safety and productivity.
5. Lighting requirements are relatively low, compared with other types of shelves, the overall investment is less.
