With reference to fig. 2-3 and fig. 6, compared with the technical solution of embodiment 7, the empty material box recycling conveyor of this embodiment may be improved as follows: a third contact 28 is further arranged on the bottom plate 14, the third contact 28, the first contact 26 and the second contact 27 are all located on the same straight line, and the third contact 28 is matched with the induction plate 25; two cam followers 17 are provided at intervals in each guide rail 21 in turn.

In practical application, when the docking platform 3 on the transport vehicle docks materials with the transport roller on the line edge material frame, a movable baffle is arranged on the transport roller on the line edge material frame at the time, the third contact 28 is arranged close to the movable baffle 12 on the transport roller 6 on the line edge material frame, two cam followers 17 are sequentially arranged on the guide rail 21 along the direction away from the electric push rod, one cam follower 17 is matched with the convex block 18 of the movable baffle 12 on the transport vehicle, and the other cam follower 17 close to the line edge material frame is used for being matched with the convex block of the movable baffle on the line edge material frame. Specifically, as shown in fig. 6, when the sensing plate 25 of the connecting rod 20 is located at the third contact 28, it indicates that the electric push rod 19 is continuously pushed out for a certain distance, that is, the guide rail 21 is pushed out for a certain distance under the action of the electric push rod 19, at this time, the cam follower 17 close to the line edge rack is in linkage with the protrusion 18 of the movable baffle 12 on the line edge rack, and the block on the line edge rack is opened, so that the empty material box on the line edge rack slides down by its own gravity and enters the docking platform 3 of the transport vehicle; meanwhile, in this state, the bump 18 on the movable baffle 12 of the butt-joint platform 3 on the transport vehicle and the corresponding cam follower 17 are still in a separation state, the movable baffle 12 has no external force influence, the movable baffle 12 is retracted downwards under the action of self gravity and the pulling force of the reset elastic piece 16 and falls back to an initial state, namely, the top end of the movable baffle 12 is lower than the upper surface of the transport roller 6, at the moment, the material entering the transport roller 6 is not blocked, at the moment, the roller is rotated, the empty material box can enter the butt-joint platform 3 of the transport vehicle, and the process can be used as the state of taking the goods (empty material box) by the butt-joint platform 3 and the butt-joint line rim charge rack on the transport vehicle. When the material is butted between the transport vehicle and the line edge material frame, only one movable baffle plate 12 needs to be added on the line edge material frame, and the extension and the retraction of the movable baffle plate 12 on the line edge material frame and the transport vehicle butt joint platform 3 can be realized by only one set of baffle plate driving mechanism 13, so that the purpose of blocking and conveying the material is realized.

Example 9

Compared with the technical scheme of the embodiment 1, the material empty box recycling transport vehicle of the embodiment can be improved as follows: the surface of said projection 18 facing the cam follower 17 has a guiding slope, which has a guiding effect facilitating the sliding of the projection 18 with the cam follower 17.

Example 10

Compared with the technical scheme of the embodiment 1, the material empty box recycling transport vehicle of the embodiment can be improved as follows: a chassis with a double-steering-wheel structure is arranged in the base 2. Because the chassis of the AGV is large, the turning radius of the AGV can be reduced by adopting a double-steering-wheel structure, and the requirement on the width of a channel is reduced; and the sideslip function of two helm structures can guarantee that AGV and work or material rest are close enough when the butt joint, can effectually avoid the card case that the butt joint space probably leads to. The chassis with dual-steering wheel structure belongs to the prior art, and therefore, the description thereof is omitted.
