Description

Storage letter sorting system

Technical Field

The utility model relates to a storage technical field especially relates to a storage letter sorting system.

Background

A core problem with automated warehousing is the efficient and automated transport of items between shelves and sorting stations. At present, a lot of warehouses begin to implement automation, a large number of mechanical devices such as an integrated goods shelf, a shuttle, a stacker, a forklift, an Automatic Guided Vehicle (AGV)/a moving trolley/a moving robot, a conveying belt and the like are equipped, labor cost is reduced, and warehousing sorting efficiency is improved.

The automated warehousing scheme using the mobile robot is easy to modularize and standardize, and a failed equipment unit can be quickly replaced. Compared with the scheme of an integrated shelf, a shuttle car and the like, the system has the advantages of less field modification and easier deployment, and is more popular in some occasions. The Kiva robot system of Amazon is a typical representative. US8831984 describes the use of submerged automatic guided carts of different load carrying capacity to effect movement of modular pallets to effect "person-to-person". However, the whole goods shelf is transported by the scheme, so that each automatic guide trolley needs to have large loading capacity, and the equipment cost is greatly increased; in addition, the shelf cannot be too high, and the increase of the storage capacity is limited. The proposal of Japan Songhe company in patent JP2004277062 is to adopt a single type of mobile robot with a lifting platform and a forking means to be butted with a goods shelf, but in order to ensure the motion stability of the robot, the number of the goods shelf layers is generally not more than three, which limits the storage capacity of a warehouse; in addition, the forking means used in this patent can only fork one-sided racks, so the roadway utilization rate is not high, and the mobile robot must have a sufficiently large self-weight, otherwise it is easy to overturn when forking heavy articles. Japanese hitachi patent CN105593143 proposes to use a submerged automatic guided cart to submerge under the shelves to move the shelves while supplying power to the conveyor belts on the shelves to effect transfer of articles between the shelves by aligning and driving the conveyor belts on both shelves. The scheme requires that an automatic guide trolley is submerged below each goods shelf for supplying power, and the cost is high because the mobile trolley with large load capacity is required for aligning the goods shelves.

To sum up, most of the existing schemes adopt a high-speed integrated goods shelf and a shuttle car, need to modify the site and install a large amount of auxiliary electromechanical devices, and are inconvenient to maintain, or need to configure a large amount of heavy-load movable trolleys with high cost although the site is less modified, and are not beneficial to popularization.
