The upper end surface of the bag-placing plate 46 is a placement plane, and the unexpanded packaging bags 44 are stacked on the bag-placing plate 46 .

[0037] The bag placing tray 46 is provided with a plurality of side fixing plates 47 and a lower fixing plate 45. The packaging bags 44 are placed in the area formed by the side fixing plates 47 and the lower fixing plates 45. The side fixing plates 47 and the lower fixing plates 45 are both slotted. The size of the placing area of ​​the bag placing tray 46 can be adjusted by cooperating with the adjusting knob 48. The adjusting knob 48 is a bolt. The bolt holes on the side fixing plates 47 and the lower fixing plates 45 are arc holes. The angles of the side fixing plates 47 and the lower fixing plates 45 are adjusted. The bolt holes on the bag placing tray 46 are long holes. The positions of the side fixing plates 47 and the lower fixing plates 45 are adjusted to accommodate packaging bags 44 of different sizes. The size range of packaging bags 44 that can be placed on the bag placing tray 46 in this embodiment is: upper width 30-40cm, lower width 25-35cm, and length 40-50cm.

[0038] The potted plant grading device 5 includes a plurality of grading conveyor belts 14 sequentially arranged along the moving direction of the potted flowers 7, and a grading swing arm 13 for moving the potted flowers 7 to the corresponding grading conveyor belt 14 according to the detection result of the potted plant detection device 2. The input end of the grading conveyor belt 14 is connected to the side of the output conveyor belt 11, and the grading swing arm 13 is a prior art, and the specific structure is not described in detail.

[0039] The output conveyor belt 11 is provided with a grading laser sensor 12 located in front of the grading conveyor belt 14. The grading laser sensor 12 is installed 10 cm in front of the grading swing arm 13. The grading swing arm 13 is swung out when the grading laser sensor 12 is triggered to send the potted flowers on the output conveyor belt 11 into the grading conveyor belt 14.

[0040] Embodiment 2: like Figure 3 As shown, the clamp includes a clamp stepper motor 32, a connecting plate 33, a movable plate 34, etc. The connecting plate 33 is fixedly connected to the lower end of the screw lifting rod 31, and the movable plate 34 is vertically slidably connected to the bottom of the connecting plate 33. The stepper motor 32 is installed in the center of the connecting plate 33, and controls the lifting and lowering of the movable plate 34 in combination with the rotating screw 35. A plurality of hooks 38 are circumferentially hinged on the outer ring of the connecting plate 33. The clamp also includes an upper connecting member 36 and a lower connecting member 37. The upper connecting member 36 is fixedly connected to the hooks 38, and one end of the lower connecting member 37 is hinged to the upper connecting member 36, and the other end is hinged to the edge of the movable plate 34. The upper connecting member 36 and the lower connecting member 37 connect the connecting plate 33, the movable plate 34 and the hooks 38, and convert the up and down movement of the movable plate 34 into the opening and closing movement of the hooks 38.

[0041] A potted flower grading and packaging method comprises the following steps: S1: The distance between the suction cups 39 and the size of the bag placing plate 46 are adjusted according to the size of the packaging bag 44, the potted plant conveying device 1 is operated, the potted flowers 7 are placed in the potted plant stopper 15 in sequence, and the grading and packaging work begins.

[0042] S2: When the potted flowers 7 reach the position of the potted detection device 2, the detection laser sensor 29 is triggered, the input conveyor belt 6 stops conveying, the rotation device 2 is actuated, and the approaching stepper motor 18 makes the rotation device 2 approach the flowers to be detected. The rotation stepper motor 20 makes the rotation belts 23 on both sides rotate forward and reverse. When the rotation belts 23 contact the potted flowers, the potted flowers make a uniform rotation motion. The industrial camera 19 performs a full range of appearance features and defect detection on the potted flowers, and automatically determines the flower level according to the evaluation index. After the detection is completed, the input conveyor belt 6 continues to convey until the next detection laser sensor 29 is triggered.

[0043] S3: The packaging mechanical claw 9 moves to the top of the potted flowers that have been inspected, the claw stepper motor 32 rotates to drive the hook claw 38 to close, so that the hook claw 38 hooks the edge of the pot, the screw lifting rod 31 rises to clamp the pot, and cooperates with the screw slide 30 to transport the potted flowers to the top of the bag supporting device 10.

[0044] S4: The pneumatic telescopic rod 41 above the packaging bag 44 extends to the plane of the packaging bag 44 in the bag placing tray 46. After the suction cup 39 sucks up the packaging bag, the telescopic rod shortens, and the rotating cylinder 43 rotates 90 degrees to complete the bag taking action. Then, the pneumatic telescopic rods 41 on both sides extend at the same time. After contact, the suction cups 39 on both sides simultaneously suck the two sides of the packaging bag 44. When the pneumatic telescopic rod shortens, the packaging bag 44 is stretched open. At the same time, the rotating cylinder 43 continues to rotate slowly, and the rotation angle is the same as the complementary angle of the side angle of the packaging bag 44, so that the two suction cup frames are in a state of being wider at the top and narrower at the bottom, which is more adapted to the shape of the packaging bag 44 and ensures that the packaging bag 44 is opened more fully. At this time, the lower edge of the stretched packaging bag 44 is parallel to the output conveyor belt 11.

[0045] S5: The lead screw lifting rod 31 descends to put the potted flowers into the packaging bag. When the bottom of the potted plant touches the output conveyor belt 11, it continues to descend by 2 cm to make the hook claw 38 separate from the edge of the pot. Then the lead screw lifting rod 31 rises, and the hook claw 38 slowly opens to make the packaging mechanical claw 9 separate from the potted plant, and the suction cup 39 stops supplying air, completing the packaging of the potted flowers.

[0046] S6: The output conveyor starts to transport the packaged potted plants, and the packaged potted plants are graded according to the rating results of the potted plant detection device 2. When the grading laser sensor 12 is triggered, the grading swing arm 13 swings out, and the potted plants flow into the grading conveyor 14 in coordination with the forward force of the potted plants, thus completing the grading and packaging of the potted flowers.

[0047] The present invention replaces manual labor by performing all-round detection, automatic packaging and automatic grading of potted flowers, reduces grading errors and product damage caused by human factors, realizes fully automatic grading and packaging of potted flowers, and improves grading and packaging efficiency.
