Both ends, resilient key 10 can guarantee positioning of the rollover stand 2 in the axially and radially both direction of torsion shaft 3 simultaneously, i.e., to turning over
Pivoted frame 2 forms axially position and radial positioning, balances the operation of rollover stand 2 more.
In addition, the utility model embodiment additionally provides a kind of automated guided vehicle (i.e. sorting AGV), sorting AGV
It is provided with a kind of pallet turnover mechanism of the utility model embodiment.Pallet can be effectively detected in the automated guided vehicle
It is no to overturn in place or return to horizontal position;Torsion shaft thereon is more stable, pallet stress more evenly, can be avoided pallet carrying goods
When object or package, cause to reduce service life because link position local stress is excessive caused by discontinuity;Prevent rollover stand and
The car body of pallet overturning overshoot damage sorting AGV.
In addition, the utility model embodiment additionally provides a kind of sorting system, which includes at least one this reality
With a kind of automated guided vehicle of new embodiment, in which: automated guided vehicle is turned over the upturned position for carrying pallet
The horizontal signal of the level angle of rotaring signal and carrying pallet is sent to sorting system;Sorting system is based on energizing signal and water
Ordinary mail number generates scheduling signals, and scheduling signals are sent to automated guided vehicle.
Sorting system can know that the operation for toppling over cargo is completed in sorting AGV according to energizing signal and horizontal signal,
And can bearing goods again, at this point, sorting system can control sorting AGV by scheduling signals executes next transport
Task transports cargo again.The sorting system can automatically control sorting AGV and execute transport task, operator needed for reducing
Member.
It, can be effective as described above as can be seen that by flip angle detection components 4, level angle detection components 5
Whether ground detection pallet 1 overturns in place or returns to horizontal position;Power Component 6 is symmetrical along the center line of pallet 1 with rotating shaft support 8
Setting, common cooperation support torsion shaft 3, rollover stand 2 are arranged symmetrically support pallet 1 along the center line of pallet 1, make torsion shaft 3 more
Stablize, 1 stress of pallet more evenly, can be avoided pallet 1 causes to subtract because link position local stress is excessive caused by discontinuity
Few service life;Gear stops pin 9 can form mechanical hard limit to rollover stand 2, limit, prevent in vertical direction to rollover stand
The only car body of rollover stand 2 and the overturning overshoot damage sorting of pallet 1 AGV.
