With the development of electronic commerce, logistics becomes an indispensable link. Express delivery commodity circulation trade development is more rapid, and the demand to the special-purpose vehicle of express delivery commodity circulation is just more, and these vehicles rely on the manual work to carry the goods into the carriage usually when letter sorting goods in, then classify the pile up neatly to the goods, waste time and energy. Sorting using shuttle cars is also available, but has limitations.

For example, in 2019, a loop type shuttle system rail transfer device and a shuttle system are disclosed in chinese utility model patent (publication No. CN 208775582U). The loop type shuttle system track transfer device comprises a driving mechanism and a transfer mechanism; the driving mechanism comprises a base, a motor and a chain, wherein the motor and the chain are both arranged on the base, and the motor drives the chain to do reciprocating motion; move and carry mechanism including removing the support, remove the support setting in the top of chain and with chain fixed connection, the chain can drive and remove the support and do reciprocating motion, removes the support and is used for bearing the removal track of loop formula shuttle system. The shuttle system comprises the loop type shuttle system track transfer device. Although the utility model discloses a can solve current shuttle moving means and need more manpower and operating personnel's personal safety does not have the problem of guarantee, this kind of shuttle structure is compact enough, the flexibility is not high, hardly uses in the letter sorting carriage to the goods in the carriage are sorted.
