Stacking machine and conical barrel stacking method based on stacking machine

The invention discloses a stacking machine and a conical barrel stacking method based on the stacking machine. The stacking machine comprises a first conveying device used for conveying a stack body, a second conveying device used for conveying a clamping plate, a transition device connected with the two conveying devices, a first pushing device, a second pushing device, an anti-toppling device and a controller. The method comprises the steps that a stack body and a clamping plate are conveyed; the second conveying device stops when the clamping plate enters the position below the transition device, the first conveying device stops when the stack body reaches the first pushing device, and the first pushing device pushes the stack body to the transition device; when the number of the stacks on the transition device reaches a preset number, the anti-toppling device and the second pushing device are started to push the stacks to the clamping plate; and when the row number of stacks on the clamping plates reaches
