The buffer mechanism 204 comprises a buffer platform, and a roller conveyor is installed on the buffer platform.
The first lifting mechanism 103 and the second lifting mechanism 203 adopt the existing chain wheel and chain lifting mechanism, and the telescopic fork 104 adopts a conventional bidirectional telescopic fork.
The number of the conveying devices 3 is at least two groups and is distributed at intervals up and down, and the number of the conveying devices 3 is two groups in the embodiment.
The conveying device 3 comprises a roller way conveying mechanism 301, and the roller way conveying mechanism 301 adopts a conventional roller way conveyor. One end of the roller way conveying mechanism 301 close to the docking device 1 is provided with a fork taking port 302 for the telescopic fork 104 to go in and out, two sides of the fork taking port 302 are respectively provided with an auxiliary roller way 303, wherein the auxiliary roller way 303 on one side and the roller way conveying mechanism 301 are driven by a same chain wheel and chain mechanism, and the auxiliary roller way 303 on the other side is an unpowered roller way.
The AGV trolley is butted with the butting device 1, the water tank is transferred to the butting device 1 through the telescopic fork 104 by the AGV trolley, transferred to the upper layer or lower layer roller way conveying mechanism 301 through the telescopic fork 104, conveyed into the buffer device 2 and temporarily stored on the buffer mechanism 204; when the water tank is needed, the water tank in the buffer device 2 is conveyed to the upper layer or the lower layer roller way conveying mechanism 301 through the buffer mechanism 204, transferred into the docking device 1 through the telescopic fork 104, and lifted to the corresponding position.
Example 2:
as shown in fig. 3, 4 and 5, the conveying device 3 further includes a blocking mechanism 304 and a centering mechanism 305, the blocking mechanism 304 is disposed above the roller conveyor 301 and behind the fork 302, and the centering mechanism 305 is disposed between the fork 302 and the blocking mechanism 304.
The water tank is transferred to the roller way conveying mechanism 301 through the telescopic fork 104 by the AGV trolley, at the moment, the position of the water tank is easy to incline due to the fact that the auxiliary roller ways 303 on the two sides of the fork taking port 302 have rotation speed difference, therefore, the water tank is subjected to speed reduction treatment through the blocking mechanism 304, and meanwhile, the centering mechanism 305 corrects the position of the water tank.
The blocking mechanism 304 includes a pair of blocking arms 3042 and hydraulic driving elements 3043, which are respectively arranged at two sides of the roller way conveying mechanism 301, and drive the blocking arms 3042 to swing from above the roller way conveying mechanism 301 to two sides of the roller way conveying mechanism 301.
