The present invention discloses a novel automatic bag stacking
machine, comprising a truss, wherein a transverse frame is slidably provided on the upper end of the truss, a material picking mechanism is provided on the transverse frame, the material picking mechanism comprises a material picking frame, a jacking device arranged on both sides of the material picking frame and a clamping arm device arranged at the lower end of the jacking device, the clamping arm device comprises a clamping arm frame, a lateral shift driving device arranged on the clamping arm frame and a clamping arm group arranged at the lower end of the frame arm frame, the jacking device can drive the clamping arm group to move up and down, and the lateral shift driving device can drive the clamping arm group to clamp and move sideways; the clamping arm group is driven to move sideways to the position of the corresponding article through the
lateral movement of the truss on the transverse frame, and then the clamping arm group is driven to move up and down through the jacking driving device, and then the clamping arm group is driven to clamp and place the article through the lateral shift driving device, and the entire stacking process is automatically controlled by a sensor and a controller, and compared with manual operation, the efficiency is higher and the stacking is flatter.
