Description

Technical Field

[0001] The invention belongs to the field of material transportation, and in particular relates to a palletizer for pellet fuel production and a use method thereof. Background Art

[0002] Pellet fuel is a heating fuel made from compressed biomass, the most common of which is wood fuel. As a form of wood fuel, wood pellets are usually made from compacted sawdust or other waste produced by sawmilling and other wood products. These wastes are then simply cut and processed to form small granular fuels for combustion.

[0003] Before using, these cut pellet fuels need to be packed into woven bags by a baler and sealed; then they are transported to the tray by a conveyor for subsequent transportation. During this process, the palletizer clamps the packaged materials on the conveyor belt and transports them to the tray. This process generally uses the camera set on the palletizer to identify, collect the position data of the packaged materials, and clamp them with claws, and then transport them to the tray after clamping to complete the palletizing operation.

[0004] Although the above method can meet the basic palletizing operation, due to the special nature of the packaged material, it is not a traditional solid square material. Therefore, when the robot arm is used for vertical clamping, after the packaged material is clamped, due to the effect of gravity, the materials on both sides are easy to accumulate in the center, which affects the stability of the clamping.
