Palletizing robot
View Patent ↗A palletizing robot includes at least one rotatable pallet; a crane comprising a rotary base, a lifting frame fixed on the rotary base, and an extensible mechanical hand slidably engaged to the lifting frame to grasp a good; and a controller. The controller controls the crane and the at least one rotatable pallet to cooperatively stack the goods on the rotatable pallet, and control the at least one rotatable pallet to rotate itself to package the stacked goods.
1. A palletizing robot, comprising:
at least one rotatable pallet;
a crane comprising:
a rotary base;
a lifting frame fixed on the rotary base, the lifting frame comprising a base plate fixed on the rotary base, a top plate, and two lifting plates interconnecting with the base plate and the top plate; the two lifting plates disposed apart and opposite to each other; each of the two lifting plates defining a pair of sliding guides at an inner surface facing the other lifting plate; and
an extensible mechanical hand slidably engaged to the lifting frame to grasp a good, the extensible mechanical hand comprising a fixing portion, a pair of sliding blocks fixed to two opposite surfaces at a proximal end of the fixing portion, an extension portion movably sleeved in a distal end of the fixing portion, a holding member fixed to an end of the extension portion away from the fixing portion, and a lift disposed on the fixing portion to drive the pair of sliding blocks to slide relative to the lifting frame; each sliding block defining a pair of sliding grooves engaged with a corresponding pair of sliding guides of the two lifting plate; and
a controller controlling the crane and the at least one rotatable pallet to cooperatively stack the goods on the rotatable pallet, and controlling the at least one rotatable pallet to rotate itself to package the stacked goods thereon.
2. The palletizing robot of claim 1 , wherein the at least one rotatable pallet comprises a platform and a motor disposed under the platform; the controller controls the motor to drive the platform to rotate.
3. The palletizing robot of claim 2 , wherein the platform is labeled to show a plurality of sections to arrange the goods on the sections in order according to a size of the goods.
4. The palletizing robot of claim 1 , wherein the crane further comprises a pair of fixed pulleys on a top of the top plate, and a pair of counterbalance weights located at a side of the lifting frame away from the extension portion; the two counterbalance weights are connected to the distal end of the fixing portion by two ropes via a corresponding fixed pulley.
5. The palletizing robot of claim 1 , wherein the at least one rotatable pallet comprises two rotatable pallets; a first of the two rotatable pallets is controlled by the controller to receive the goods, and a second of the rotatable pallets is controlled by the controller to rotate itself to package the goods.
