[0002] After harvesting, flowers need to be graded based on indicators such as flower openness, stem length and diameter, color, and the presence of defects, so that they can be priced according to quality and packaged for sale. Currently, the industry generally uses "sorting tables + manual visual inspection" for grading, which has the following shortcomings:

[0003] 1) Manually comparing the length of the flower stems and the size of the flowers one by one, the grading standards vary from person to person, and the consistency is poor, resulting in the entire bundle being forced to be downgraded, which directly affects the selling price;

[0004] 2) It is completely dependent on manual labor, which is labor-intensive, has low production capacity, and is difficult to meet large-scale delivery needs;

[0005] 3) Repeated manual handling and insertion of flower stems can cause flower damage, serious cross-contamination with gray mold, and a high flower loss rate;

[0006] 4) Manual cutting of flower stems will result in large errors in length, and further trimming will increase losses.

[0039] The cut flower visual grading equipment provided by the present invention features a primarily sheet metal frame, which is 30% lighter than traditional aluminum profiles and more convenient to install and relocate. The flower feeding device 3, sterilization device 4, visual inspection device 5, flower stem cutting device 6, and grading buffer device 7 are located in the loading area, sterilization area, visual inspection area, flower stem cutting area, and grading buffer area of ​​the single flower conveyor line 2, respectively.

[0040] Single flower conveying main line 2:

[0041] The single flower conveying main line 2 includes a main line conveyor belt assembly 21 arranged in a ring shape, a plurality of flower plate supports 22 surrounding and spaced apart on the main line conveyor belt assembly 21, and a guide and limit clamping rail 23 surrounding and arranged on the outside of the main line conveyor belt assembly 21; the middle part of the flower plate support 22 is guided and limited by the guide and limit clamping rail 23; the main line conveyor belt assembly 21 includes a main line drive servo motor, and the encoder position of the main line drive servo motor is correlated in real time with the encoder position of the flower pushing servo motor 344.

[0042] Furthermore, the main conveyor belt assembly 21 includes a main drive servo motor, a speed reducer, a bracket, a driving pulley, a driven pulley, a perforated timing belt, and a guide bar. The main conveyor belt assembly 21 uses a perforated timing belt to drive the flower tray, supporting the movement of the flowers. The flower tray 22 holds the flowers, preventing contact around the flowers and preventing damage.

[0043] Specifically, the inner end of the torus plate 22 is fixed to the main conveyor belt assembly 21, and the outer end of the torus plate 22 is provided with a notch. The torus plate 22 supports the flowers through the notch and moves under the drive of the main conveyor belt assembly 21. The torus plate 22 is made of UPE material, which has excellent strength and toughness and does not damage the flower stems and flowers.

[0044] In a specific embodiment, the center distance between two adjacent flower trays 22 is 100 mm, the production capacity is 10,800 flowers per hour, and one flower is produced in 0.33 seconds. The moving speed of the flower tray 22 is 300 mm / s. The moving speed is reduced while ensuring the production capacity, and the impact and vibration are small. The main line conveyor belt assembly 21 adopts synchronous belt drive with low noise, no oil pollution, and little impact on surrounding operators.

[0045] The guide and limit clamping rails 23 consist of upper and lower rails arranged one above the other. The center of the torus plate 22 slides between the upper and lower rails to prevent the torus plate 22 from swinging up and down during movement. A servo motor and a speed reducer drive the timing belt, and the guide and limit clamping rails 23 are installed to drive the torus plate 22 to move precisely.

[0046] Flower pushing device 3:

[0047] The flower pushing and loading device 3 includes a feed conveyor belt assembly 31, a flower pushing plate mechanism 32 and a flower blocking plate mechanism 33 arranged at the discharge end of the feed conveyor belt assembly 31, and a crank rocker mechanism 34 for driving the flower pushing plate mechanism 32 to push the flowers into the single flower conveying main line 2; the flower pushing plate mechanism 32 and the flower blocking plate mechanism 33 are arranged opposite to each other; when the flower pushing plate mechanism 32 extends to push the flowers out of the feed conveyor belt assembly 31, the flower blocking plate mechanism 33 retracts; when the flower pushing plate mechanism 32 retracts, the flower blocking plate mechanism 33 extends to block the flowers in the feed conveyor belt assembly 31.

[0048] The infeed conveyor assembly 31 consists of a round belt loading section and a soft-pack timing belt clamping section. A slide bar is installed at the bottom of the clamping section to provide guidance and prevent damage to the flowers' surfaces. The round belt loading section utilizes a polyurethane round belt, while the clamping section utilizes a PU timing belt covered in black foam. This combination of round belt and soft-pack timing belt conveyor structure provides better protection for the flowers and stems, further minimizing surface damage. A position sensor is installed at the discharge end of the infeed conveyor assembly 31. Once the flowers are in position, the conveyor stops and rapidly counts the flowers, calculating total input capacity and recording the workload of each loading operator.

[0049] The crank-rocker mechanism 34 comprises a crank 341, a rocker 342, a connecting block 343, and a flower-pushing servo motor 344 connected to the crank 341. The connecting block 343 is also connected to a first sliding assembly 345, which is arranged along the conveying direction of the feed conveyor belt assembly 31. The crank-rocker mechanism 34 enables the flower-pushing plate mechanism 32 to push flowers from the feed conveyor belt assembly 31 one by one onto the single-flower conveyor main line 2, achieving fast forward and reverse movement and reducing impact and vibration, an effect not achievable with a pneumatic drive or other similar mechanism. It is worth noting that the crank-rocker mechanism 34 utilizes a flower-pushing servo motor 344 + crank-rocker structure. The encoder binding angle between the flower-pushing servo motor 344 and the main line drive servo motor is adjusted based on the operating speed of the flower tray 22 to quickly push flowers onto the line, preventing duplicate loading or unloaded flower trays 22.

[0050] The flower plate pusher mechanism 32 includes a flower plate pusher 321, a second sliding assembly 322 for guiding the extension and retraction of the flower plate pusher 321, and a flower plate pusher driver 323 for driving the extension and retraction of the flower plate pusher 321. The flower plate retaining mechanism 33 includes a flower plate retaining 331, a third sliding assembly 332 for guiding the extension and retraction of the flower plate retaining 331, and a flower plate retaining driver 333 for driving the extension and retraction of the flower plate retaining 331. The second sliding assembly 322 and the third sliding assembly 332 are both arranged perpendicular to the conveying direction of the feed conveyor belt assembly 31. Specifically, the flower plate pusher driver 323 and the flower plate retaining driver 333 both use pneumatic cylinders, and these two cylinders are controlled by the same solenoid valve with the air pipes reversed. When the signal is driven, the flower plate retaining 331 retracts and the flower plate pusher 321 extends, and the two operations alternately and with a high degree of coordination.

[0051] Furthermore, the first sliding assembly 345 , the second sliding assembly 322 , and the third sliding assembly 332 all include sliders and slide rails.

[0052] In one embodiment, four flower pusher and feeder devices 3 are provided. Operators at four workstations pick up raw flowers from the loading conveyor line 1 and hang them one by one on the infeed conveyor assembly 31. The first flower pusher and feeder device 3 pushes fresh flowers onto the first, fifth, ninth, thirteenth, and so on, of the flower trays 22 that arrive in sequence. Empty flower trays 22 are then pushed onto fresh flowers by the three subsequent flower pusher and feeder devices 3.

[0053] Specifically, the angular position of each flower plate holder 22 is recorded by the encoder of the main line drive servo motor. The main line drive servo motor is the "main shaft", and its encoder position is used as a reference; the flower pushing servo motor 344 is the "slave shaft", and its encoder position follows the main shaft position in real time to ensure that the flower pushing action is accurately synchronized with the arrival time of the flower plate holder 22, so that the flower pushing online device 3 can accurately push the flowers into the flower holder plate 22.

[0054] Visual inspection device 5:

[0055] The visual detection device 5 includes a flower top visual assembly 51 arranged above the flower plate support 22, a flower side visual assembly 52 arranged outside the flower plate support 22, and a stem visual assembly 53 arranged below and inside the flower plate support 22.

[0056] In addition, the visual detection device 5 further includes a backlight plate, and the flower top visual assembly 51, the flower side visual assembly 52, and the stem visual assembly 53 each include a camera and a light source. The visual detection device 5 is arranged at one end of the single-flower conveying main line 2. When the fresh flowers turn around, the flower top visual assembly 51 detects from the top of the flower, and the flower side visual assembly 52 detects from the side of the flower, so as to determine the appearance parameters of the flower such as the openness, the cup height, the color brightness, and the defect. The stem visual assembly 53 detects from the back of the flower stem, so as to confirm the appearance parameters of the stem such as the length and the diameter. Through the synchronous imaging of the three cameras of the “flower top visual + flower side visual + flower stem visual”, all the key parameters of the flower such as the height, the openness, the color, the defect, and the length and the diameter of the flower stem are obtained. The system automatically grades according to the preset standard, the grading error is small, far exceeding the accuracy of the human visual judgment, the single-bundle consistency is high, and the price reduction loss caused by human error is significantly reduced.

[0057] Flower stem cutting device 6:

[0058] The flower stem cutting device 6 includes a cutting support frame 61, and a plurality of cutting knife mechanisms 62 arranged in the vertical direction on the cutting support frame 61; the cutting knife mechanism 62 includes an opposite knife groove assembly and a cutting knife assembly; the knife groove assembly includes a knife groove block 621 and a knife groove driving member 622 for driving the knife groove block 621 to approach the cutting knife assembly; and the cutting knife assembly includes a cutting knife 623 and a cutting knife driving member 624 for driving the cutting knife 623 to approach the knife groove assembly. Specifically, the knife groove driving member 622 and the cutting knife driving member 624 each adopt a pneumatic cylinder.

[0059] After the visual detection device 5 determines the grade, the knife groove assembly and the cutting knife assembly act according to the preset stem length of the current fresh flower corresponding to the grade, so as to automatically cut the flower stem, reduce the manual cutting workload, and be efficient and fast.

[0060] In a specific embodiment, the cutting knife mechanism 62 is provided as 10, and the 10 cutting knife mechanisms 62 are arranged in the vertical direction on the cutting support frame 61. The upper and lower two cutting knife mechanisms 62 are arranged in a staggered manner, so as to realize full coverage of every 5mm length in the range of 35mm to 80mm. The cutting knife is automatically selected according to the feedback of the visual detection device 5, so as to eliminate manual secondary pruning.

[0061] Furthermore, the cutter 623 uses a standard 18×100×0.5-60 degree utility blade, which reduces consumable costs. A blade slot block 621 is provided on the opposite side, with a slotted edge to ensure smooth cutting. Once the flower stem is in place, the cutting blade mechanism 62 at each location initiates cutting based on the visually fed length information.

[0062] Hierarchical cache device 7:

[0063] The hierarchical cache device 7 includes a plurality of hierarchical cache slides 71 arranged in parallel, and a lower material pushing assembly 72 corresponding to each hierarchical cache slide 71; the lower material pushing assembly 72 is arranged on the lower inner side of the flower support plate 22; the lower material pushing assembly 72 includes a pushing rod 721, and a lower material pushing driving component 722 for driving the pushing rod 721 to extend and retract; specifically, the lower material pushing driving component 722 adopts a cylinder.

[0064] Each tiered buffer chute 71 has a counting sensor at the inlet end to count the number of flowers entering the tiered buffer chute 71, facilitating timely notification of manual collection. A blocking rubber strip is installed at the outlet end of the tiered buffer chute 71 to prevent the flowers from flying out of the tiered buffer chute 71 due to excessive speed.

[0065] The graded cache slide 71 adopts a mirror-finished stainless steel round tube slide, and the flowers slide out with a smooth transition without damaging the flowers.

[0066] Specifically, the hierarchical cache slides 71 are set to 32, which can be flexibly increased or decreased according to the distribution ratio of each level and the proportion of each level to ensure inventory and avoid shutdown due to full material. The cache capacity of a single level is ≥200 pieces to avoid frequent shutdowns for collecting flowers.

[0067] According to the grading results of the visual inspection device 5, when the flowers move to the feeding end of the graded cache slide 71 of the corresponding grade, the flower unloading and pushing driving component 722 starts and pushes out in advance according to the operating speed, and pushes the flowers into the graded cache slide 71 in a parabolic manner; the advance time of starting the flower unloading and pushing driving component 722 is bound by a function and the speed of the main line drive servo motor. The speed of the single flower conveying main line 2 changes, and the advance amount of the flower pushing time is automatically calculated and compensated to avoid the flowers failing to enter the graded cache slide 71.

[0068] Sterilization device 4:

By combining the first and second UV lamps, they kill gray mold online and extend shelf life by 2-3 days. A DC ballast 41 is installed on the top to prevent water dripping from the flower stems from affecting electrical circuits.

[0071] Feeding conveyor line 1:

[0072] The feeding conveyor line 1 includes a sequentially connected wool flower feeding section 11, an elevator climbing section 12, and a wool flower picking section 13. The height of the wool flower picking section 13 is greater than that of the wool flower feeding section 11. The elevator climbing section 12 facilitates ground personnel to load wool flower into the wool flower feeding section 11 and to manually remove wool flower from the wool flower picking section 13 and hang it on the wool flower pushing and loading device 3.

[0073] Furthermore, the feeding conveyor line 1 includes a conveyor belt, a driving wheel, a driven wheel, and a speed regulating motor. The conveyor belt adopts a diamond-patterned conveyor belt with high surface friction. It is driven by a speed regulating motor and the conveyor belt speed is adjustable from 2 to 10 m / min.

[0074] At the same time, a manual operating platform is set between the feeding conveyor line 1 and the single flower conveying main line 2, and the flower pushing device 3 is installed on the manual operating platform. Stairs are set at both ends of the manual operating platform to facilitate people to go up and down.

[0075] Furthermore, the servo encoder of the mainline drive servo motor records the different angles of the different receptacle plates 22, thus recording the current position of each flower on the line. During loading, the encoder position of the mainline drive servo motor is linked in real time with the encoder position of the flower push servo motor 344, enabling control of the timing of flower push, thereby precisely pushing the flowers into the receptacle plates 22. During unloading, the encoder of the mainline drive servo motor records the angular position of each receptacle plate 22. Based on the grading results of the visual inspection device 5, flowers of corresponding grades are pushed out of different grade buffer slides 71.

[0076] The workflow of the present invention is as follows:

[0077] 1) Manually place the woolen waste pile on a snakeskin bag and place it on the woolen waste loading section 11 of the feeding conveyor line 1. The woolen waste is automatically transported to the woolen waste discharging section 13 via the lifting climbing section 12;

[0078] 2) manually picking up the hair flowers from the hair flower picking section 13 and hanging them one by one on the feed conveyor assembly 31, which stops after conveying the flowers to the discharge end;

[0079] 3) When the flower tray 22 of the single flower conveying main line 2 is in place, the flower blocking plate driving member 333 drives the flower blocking plate 331 to retract, and the flower pushing plate driving member 323 drives the flower pushing plate 321 to extend, and the crank rocker mechanism 34 is actuated to push the flowers into the flower tray 22;

[0080] 4) The flower plate driver 333 drives the flower plate 331 to extend, and the flower plate driver 323 drives the flower plate 321 to retract, and the crank of the crank rocker mechanism 34 returns to the starting position;

[0081] 5) The single flower conveyor main line 2 conveys the flowers to the ultraviolet sterilization area of ​​the first and second ultraviolet lamps, which irradiate the flowers and stems to remove gray mold;

[0082] 6) The single flower conveyor line 2 continues to convey the flowers to the visual inspection area. The visual inspection device 5 collects various information about the flowers. The system compares the information with the flower grading standards and determines the corresponding grade of each flower.

[0083] 7) The single flower conveying main line 2 continues to convey the flowers to the flower stem cutting area. According to the grading results fed back by the visual inspection device 5, the cutting knife mechanism 62 of the corresponding height is activated to cut;

[0084] 8) Based on the flower grade determined by the system, the single flower conveying main line 2 moves the flowers to the grading buffer slide 71 of the corresponding grade, and the flower unloading and pushing assembly 72 pushes the flowers into the grading buffer slide 71.
