Description

Technical Field

[0001] This invention relates to the field of palletizing devices, and in particular to a carton palletizing machine and its usage method. Background Technology

[0002] A palletizer is a common device for picking up and handling items. A typical palletizer uses a robotic arm to move a gripper, which picks up the items and moves the gripper and items together to stack them.

[0003] When palletizing cartons, palletizers typically use grippers to grasp the outer walls of the cartons and compress the top of the outer walls. To ensure stable gripping and handling, the grippers need to continuously press and fix the outer walls of the cartons. However, because the inside of the cartons is corrugated, the outer walls are fragile. When the grippers continuously compress the outer walls, it can easily damage the cartons. Furthermore, the grippers mostly clamp the top of the cartons, fixing them only through the compressive force between the grippers and the outer walls. The bottom of the cartons lacks support, which can easily cause instability when the robotic arm moves the cartons. Summary of the Invention

[0043] The present invention also provides a method for using a carton palletizer, including the following specific steps:

[0044] Step 1: First, the robotic arm moves the mounting frame and clamping blocks to the top of the carton on the conveyor belt, so that the two clamping blocks are positioned on both sides of the carton. As the motor runs, it drives the first bevel gear to rotate. The meshing action of the first and second bevel gears causes the second bevel gear and the connecting rod to rotate together. As the connecting rod rotates, it drives the two clamping blocks to move towards each other at both ends of the connecting rod, so that the outer wall of the clamping blocks fits against the two sides of the carton, thus limiting and fixing the carton.

[0045] Step 2: Then, by moving the clamping block, the support block and connecting block move together. The connecting block moves the bottom of the movable block together, causing the movable block to rotate around the fixed axis. The bottom of the movable block presses down on the connecting block, and the connecting block moves the top of the movable rod downward together. The bottom of the movable rod pushes the support block downward and slides in the inner cavity of the mounting groove, so that the bottom of the support block presses against the arc surface of the limiting block. The support block rotates to one side around the mounting axis. When the clamping block is in contact with the outer wall of the carton, the support block rotates to the lower surface of the carton, lifting and supporting the lower surface of the carton upward.

[0046] Step 3: Next, the support block lifts the carton upward, causing the upper surface of the carton to press against the suction cups and mounting rods. This causes the compression block to compress the spring and the suction cups, resulting in multiple suction cups adhering to the upper surface of the carton to ensure stable gripping. Then, the robotic arm drives the carton to rotate and move for stacking.

[0047] The technical effects and advantages of this invention are as follows:

[0048] (1) The present invention utilizes a combination of clamping block, support block, limiting block, mounting shaft, movable rod, connecting block and movable block. By moving the clamping block, the support block and connecting block move together. The connecting block moves the bottom of the movable block together, so that the movable block rotates around the fixed shaft. The bottom of the movable block presses down on the connecting block. The connecting block moves the top of the movable rod down together. The bottom of the movable rod pushes the support block down to slide in the inner cavity of the mounting groove, so that the bottom of the support block presses against the arc surface of the limiting block. The support block rotates around the mounting shaft to one side. When the clamping block is in contact with the outer wall of the carton, the support block rotates to the lower surface of the carton, lifting and supporting the lower surface of the carton, improving the stability of the carton gripping and reducing the squeezing damage to the carton.

[0049] (2) The present invention utilizes the combination of clamping blocks, movable grooves, connecting rods, first bevel gears and second bevel gears. The mechanical arm drives the mounting frame and clamping blocks to move above the carton on the conveyor belt, so that the two clamping blocks are set on both sides of the carton. As the motor runs, it drives the first bevel gear to rotate. The meshing action of the first bevel gear and the second bevel gear causes the second bevel gear and the connecting rod to rotate together. As the connecting rod rotates, it drives the two clamping blocks to move towards each other at both ends of the connecting rod, so that the outer wall of the clamping block fits against the two sides of the carton, which facilitates the limiting and fixing of the carton.

[0050] (3) The present invention utilizes a combination of support blocks, suction cups, movable rods, extrusion blocks and compression springs. The support blocks lift the carton upwards, causing the upper surface of the carton to press upwards against the suction cups and mounting rods. This causes the extrusion blocks to compress the compression springs and the suction cups, resulting in multiple suction cups adhering to the upper surface of the carton. This ensures stable gripping of the carton. The robotic arm then drives the carton to rotate and move, improving the stability of the carton gripping and facilitating the stacking of the carton.

The first bevel gear 36 is located at the top of the inner cavity of the mounting bracket 32. Both ends of the connecting rod 37 are rotatably inserted into the inner wall of the mounting bracket 32. The connecting rod 37 has reverse threads at both ends. One end of the connecting rod 37 is threaded into the top of the clamping block 34.

The connection is as follows: one end of the mounting shaft 44 is slidably inserted into the inner cavity of the connecting groove 43; the top of the support block 41 is connected to the bottom of the clamping block 34 via the mounting shaft 44 and the connecting groove 43, allowing the support block 41 to rotate around the mounting shaft 44; the movable rod 45 is slidably inserted into the clamping block 34, and the movable rod 45 is used to drive the support block 41 to move in the vertical direction; the bottom of the connecting shaft 46 is fixedly inserted into the movable rod 45; both ends of the connecting shaft 46 are rotatably inserted into the inner wall of the support block 41; the bottom of the movable rod 45 is rotatably connected to the top of the support block 41 via the connecting shaft 46; the connecting shaft 46 and the mounting shaft 44 are at the same axial position; the upper surface of the limiting block 47 is connected to the clamping block 34. The bottom end of the 4 is fixedly connected, and the position of the limiting block 47 corresponds to that of the support block 41. The limiting block 47 is used to squeeze the support block 41, so that the support block 41 is tilted. The counterweight block 412 is fixedly inserted and connected to the bottom of the support block 41. The counterweight block 412 is used to increase the weight of the support block 41 and lower the center of gravity of the support block 41, ensuring that the support block 41 is set vertically downward.

[0066] First, the robotic arm 2 moves the mounting frame 32 and the clamping block 34 to the top of the carton on the conveyor belt 1, so that the two clamping blocks 34 are positioned on both sides of the carton. As the motor 35 runs, it drives the first bevel gear 36 to rotate. The meshing action of the first bevel gear 36 and the second bevel gear 38 causes the second bevel gear 38 and the connecting rod 37 to rotate together. As the connecting rod 37 rotates, it drives the two clamping blocks 34 to move towards each other at both ends of the connecting rod 37, so that the outer wall of the clamping block 34 fits against the two sides of the carton, thus limiting and fixing the carton.

[0067] Then, by moving the clamping block 34, the support block 41 and the connecting block 48 move together. The connecting block 48 moves the bottom of the movable block 49 together, so that the movable block 49 rotates around the fixed shaft 410. The bottom of the movable block 49 presses the connecting block 48 downward. The connecting block 48 moves the top of the movable rod 45 downward together. The bottom of the movable rod 45 pushes the support block 41 downward and slides it in the inner cavity of the mounting groove 42, so that the bottom of the support block 41 presses against the arc surface of the limiting block 47. The support block 41 rotates to one side around the mounting shaft 44. When the clamping block 34 is in contact with the outer wall of the carton, the support block 41 rotates to the lower surface of the carton, lifting and supporting the lower surface of the carton upward.

[0068] Next, the cardboard box is lifted upward by the support block 41, so that the upper surface of the cardboard box presses upward against the suction cup 51 and the mounting rod 52, which drives the pressing block 54 to compress the compression spring 55 and compress the suction cup 51, so that multiple suction cups 51 adhere to the upper surface of the cardboard box to ensure stable gripping of the cardboard box. Then, the robotic arm 2 drives the cardboard box to rotate and move, and stacks the cardboard box.

A carton palletizing machine according to claim 5, characterized in that, The limiting block (47) has an arc-shaped side, the connecting block (48) has a U-shaped side, the inner cavity of the connecting block (48) is slidably inserted into one end of the connecting rod (37), and the inner cavity of one end of the movable block (49) is slidably inserted into one end of the connecting rod (37).

7. The method of using a carton palletizer according to claim 6, characterized in that, The specific usage steps are as follows: Step 1: First, the mechanical arm (2) drives the mounting frame (32) and clamping blocks (34) to move above the carton on the conveyor belt (1), so that the two clamping blocks (34) are set on both sides of the carton. As the motor (35) runs, it drives the first bevel gear (36) to rotate. By utilizing the meshing action of the first bevel gear (36) and the second bevel gear (38), the second bevel gear (38) and the connecting rod (37) rotate together. As the connecting rod (37) rotates, it drives the two clamping blocks (34) to move towards each other at both ends of the connecting rod (37), so that the outer wall of the clamping block (34) fits against the two sides of the carton, thus limiting and fixing the carton. Step 2: Then, by moving the clamping block (34), the support block (41) and the connecting block (48) move together. The connecting block (48) moves the bottom of the movable block (49) together, so that the movable block (49) rotates around the fixed shaft (410). The bottom of the movable block (49) presses the connecting block (48) downward. The connecting block (48) moves the top of the movable rod (45) downward together. The bottom of the movable rod (45) pushes the support block (41) downward to slide in the inner cavity of the mounting groove (42), so that the bottom of the support block (41) presses against the arc surface of the limiting block (47). The support block (41) rotates around the mounting shaft (44) to one side. When the clamping block (34) is in contact with the outer wall of the carton, the support block (41) rotates to the lower surface of the carton, lifting and supporting the lower surface of the carton upward. Step 3: Next, the cardboard box is lifted upward by the support block (41), so that the upper surface of the cardboard box presses the suction cup (51) and the mounting rod (52) upward, which drives the pressing block (54) to compress the compression spring (55) and compress the suction cup (51), so that multiple suction cups (51) adhere to the upper surface of the cardboard box to ensure stable gripping of the cardboard box. Then, the robotic arm (2) drives the cardboard box to rotate and move, and stacks the cardboard box.
