The stick bodies 500 are counted by the induction counter 113. After being sent out from the conveyor belt 106, the stick bodies 500 fall on the first bracket 403 and the second bracket 404 of the transfer mechanism 400. After the first bracket 403 and the second bracket 404 receive a predetermined number of stick bodies, they are transported to the bottom of the lifting drive mechanism 201 along the first conveyor belt 401 and the second conveyor belt 402.

The first manipulator assembly and the second manipulator assembly release the bundled stick body 500, and the lifting drive mechanism 201 drives the bundled stick body to descend, and transfers the stick body to the first bracket 403 and the second bracket 404, and then the lifting drive mechanism 201 lifts the unbound stick bodies in the next group of first brackets 403 and second brackets 404 to carry out the next bundle of stick bodies.

[0104] The bundled sticks are transported to the first receiving claw 303 and the second receiving claw 308 through the transfer mechanism 400. As the receiving turntable 301 rotates, the sticks are rotated to the bottom of the pressing plate 311. The pressing plate driving mechanism 309 drives the pressing plate 311 to move and squeeze the sticks in the circumferential direction, so that the whole bundle of sticks is leveled. The clamping plate driving mechanism drives the first clamping plate 313 and the second clamping plate 314 to squeeze the sticks in the axial direction and stack the sticks neatly. The receiving turntable 301 rotates to transfer the neatly arranged sticks to the hopper and slides to a predetermined position (such as a basket).
