[0057] Step S5, then control the bottle clamping mechanism to drive the conveying bottle to move to the bottle feeding bracket 101. During the movement, the lower bottle closing part of the lower bottle cap of the conveying bottle collides with the first bottle closing block to close the lower bottle cap of the conveying bottle. At the same time, the upper bottle closing part of the upper bottle cap of the conveying bottle collides with the second bottle closing block to close the upper bottle cap of the conveying bottle. Then the bottle clamping mechanism drives the conveying bottle to move to the bottle feeding bracket 101.

[0058] Step S6, then control the bottle clamping mechanism to release the conveying bottle and drop it into the bottle feeding bracket 101, and then reset the bottle clamping mechanism. Finally, control the fourth driving device 102 to drive the bottle feeding bracket 101 to send the conveying bottle into the bottle outlet pipe 3 for return.

[0059] To sum up, the present embodiment can automatically complete the material unloading operation of the conveyor bottle. The staff only needs to obtain the materials directly at the workstation without operating the workstation. Therefore, the present invention does not need to be equipped with professional operators at each workstation.
