Detailed Implementation
[0018] like Figure 1-2 As shown, to achieve the above objectives, this utility model employs the following technical solution:
[0019] A pallet packaging correction mechanism is disclosed, used to adjust the position of packaging boxes 12 on pallets 14 to ensure neat stacking and accurate positioning. The mechanism is installed based on a conveyor belt assembly 1, with baffles 1.1 on both sides of the conveyor belt assembly 1 to block the pallets 14 and ensure the conveying path of the pallets 14. An outer frame 3 is erected above the conveyor belt assembly 1; a side-pressure top rail 6 is fixed to the inner top of the outer frame 3; the direction of the side-pressure top rail 6 is perpendicular to the conveying direction along the conveyor belt assembly; a side-pressure bottom rail 5 is fixed to the inner bottom of the outer frame 3; a side-pressure component 4 is slidably disposed between the side-pressure top rail 6 and the side-pressure bottom rail 5; the bottom of the side-pressure component 4 is threaded onto a side-pressure screw 7; the side-pressure screw 7 is driven by a first motor 8 to move the side-pressure component 4 in opposite directions; pallet limiting members 2 are provided within the gaps of the conveyor belt assembly 1 to fix the pallets 14.
[0020] like Figure 1-2 As shown, the pallet limiting component 2 includes: a limiting rotating rod 2.1, a support 2.2, and a third motor 2.3; the support 2.2 is fixed to the side plate of the conveyor belt assembly 1; the third motor 2.3 is fixed on the support 2.2; the drive end of the third motor 2.3 is connected to the end of the limiting rotating rod 2.1; a protrusion is fixed to the head end of the limiting rotating rod 2.1, and when the limiting rotating rod 2.1 is rotated to a vertical position, the protrusion enters the insertion hole of the pallet 14; the pallet limiting component 2 is located at both ends of the pallet 14 along the conveying direction, restricting the movement of the pallet 14. The pallet limiting component 2 is used to fix the position of the pallet 14 and adjust the packaging box 12 above it based on the position of the pallet 14. A photoelectric switch 9 can be installed on the outer frame 3 to sense whether the pallet 14 is in position.
[0021] like Figure 1-2 As shown, the outer frame 3 is movably provided with front adjustment members 10 at both ends along the conveying direction; the shaft of the front adjustment member 10 is driven by the second motor 11, which drives the front adjustment member 10 to rotate. When the front adjustment member 10 rotates to above the conveyor belt group 1 and is perpendicular to the conveying direction of the conveyor belt group 1, it restricts the position of the packaging box 12 along the moving direction.
[0022] like Figure 1-2As shown, the side pressure assembly 4 is symmetrically arranged on both sides of the conveyor belt group 1; the side pressure assembly 4 includes: a side pressure frame 4.1, a side pressure rod 4.2, a buffer spring 4.3, and a side pressure plate 4.4; the upper and lower ends of the side pressure frame 4.1 are provided with sliding grooves and respectively cooperate with the side pressure top rail 6 and the side pressure bottom rail 5; the side pressure rod 4.2 is movably provided on the frame of the side pressure frame 4.1; a side pressure plate 4.4 is fixed on the side pressure rod 4.2 on the same side; the side pressure rod 4.2 located between the side pressure plate 4.4 and the side pressure frame 4.1 is fitted with a buffer spring 4.3. The side pressure frame 4.1 is provided with two sets on each side; the side pressure frames 4.1 on the same side are fixedly connected by reinforcing ribs 4.5 and move synchronously; the bottom of one set of side pressure frames 4.1 is provided with a threaded hole; the side pressure screw 7 is movably inserted in the threaded hole and driven by the first motor 8; the bottom of the other set of side pressure frames 4.1 is provided with a through hole; a guide rod 13 is inserted in the through hole. The side pressure plate 4.4 and the front adjustment piece 10 correspond to the height of the gaps in the packaging box 12. Currently, three layers of packaging boxes 12 are placed on our pallet 14, with each layer corresponding to a gap on both sides. A set of side pressure plates 4.4 is installed at each gap. The width of the side pressure plates 4.4 is greater than the gap to prevent misalignment of the packaging boxes 12 during adjustment. Unless otherwise described, the fixing methods used above are welding or threaded fastening using common techniques employed by industry professionals.
[0023] Workflow:
[0024] After the pallet 14 carrying the packaging box 12 enters the outer frame 3, the photoelectric switch 9 is triggered, the conveyor belt group 1 stops moving, and the limiting rod 2.1 of the pallet limiting component 2 of the third motor rotates to fix and limit the front and rear ends of the pallet 14. After the pallet 14 is positioned, the side pressure frame 4.1 is driven by the first motor 8 to move in opposite directions, and the side pressure rod 4.2 returns to the position of the two sides of the packaging box 12; then the front adjustment component 10 is controlled by the second drive motor to rotate and align the surfaces of the two ends of the packaging box 12 in the conveying direction. After the alignment task is completed, the third motor drives the limiting rod 2.1 to reset, the second motor 11 drives the front adjustment component 10 to reset, the first motor 8 drives the side pressure plate 4.4 to reset, and the conveyor belt group 1 is started to continue running, and the pallet 14 continues to move to the packaging position.
