When the position information of the box 150 in the third state, which is acquired by the controller through the second position sensor, meets the second preset position, the controller controls the second actuator 131 not to extend out any more.
As will be understood by referring to the drawings in the sequence of fig. 5 to fig. 2, the controller controls the second actuator 131 to retract, and drives the first link 141 to rotate through the second transmission rod 132, and also synchronously drives the second link 142 and the third link 143 to rotate (at this time, the fourth link 144 is kept still under the action of the first actuator 121 and the first transmission rod 122) due to the motion characteristics of the four-bar linkage 140, so that the box 150 is switched from the third state to the second state, and the turning of the box 150 is reset.
Subsequently, as will be understood by referring to the drawings in the sequence of fig. 5 to fig. 2, the controller controls the first actuator 121 to retract, and drives the fourth link 144 to rotate via the first transmission rod 122, and also synchronously drives the second link 142 and the third link 143 to rotate (at this time, the first link 141 is kept still under the action of the second actuator 131 and the second transmission rod 132) due to the motion characteristic of the four-link mechanism 140, so that the box 150 is switched from the second state to the first state (as shown in fig. 3, during the switching process, the box 150 passes through an intermediate state between the first state and the second state), and the reset of the lifting of the box 150 is realized.
