Description

Technical Field

[0001] This invention relates to the field of tobacco leaf packaging technology, and in particular to an automatic tobacco leaf packing device and method. Background Technology

[0002] Before baling, tobacco leaves need to be pre-compressed and packed into boxes. The boxes then carry the tobacco leaves into the baling system for final compression and packaging. However, during the pre-packaging stage, tobacco leaves from multiple baskets are manually poured into the boxes. This process is labor-intensive, inefficient, and prone to inconsistencies, resulting in inconsistent leaf sizes and ultimately non-standardized packaged leaves. This affects subsequent stacking and transportation. Therefore, there is an urgent need to design a more efficient technical solution that ensures standardized stacking of tobacco leaves during packaging. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic tobacco leaf packing device and method to solve the problems existing in the prior art, which has high working efficiency and ensures standardized stacking of tobacco leaves during packing.

[0013] Preferably, the flipping manipulator includes a rotary mechanism connected to the vertical moving guide rail pair. The rotary mechanism includes a rotary frame, on which a rotary motor is mounted. The rotary motor drives a rotary shaft via gear meshing. The rotary shaft at the bottom of the rotary mechanism is connected to a portal frame. A flipping mechanism is provided on the inner side of the bottom of the portal frame. A locking mechanism is installed at the end of the flipping mechanism. The locking mechanism can fix and clamp the tobacco basket to the side wall. The flipping mechanism includes a flipping frame located at the side wall of the portal frame. A horizontally arranged rotary motor is mounted on the flipping frame. The rotary motor's shaft is connected to the locking frame. The locking frame is equipped with a locking mechanism. The locking mechanism uses a claw driven by an electric push rod or a claw driven by a hydraulic cylinder.

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] The purpose of this invention is to provide an automatic tobacco leaf packing device and method to solve the problems existing in the prior art, which has high working efficiency and ensures standardized stacking of tobacco leaves during packing.

[0040] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Because tobacco leaves have stems at one end, manual stacking in tobacco boxes results in poor uniformity. When manually pouring the tobacco leaves from the basket into the box, the stem side and the other side are unevenly thick, causing the tobacco leaves in the box to form a wedge shape, which is detrimental to subsequent packaging. To solve this problem, this invention provides an automatic tobacco leaf packing device. (Refer to...) Figures 1 to 7 As shown, the assembly includes a conveying mechanism, a three-coordinate frame 1, and a flipping robot. The conveying mechanism is located on one side of the tobacco box 19 and is used to convey the tobacco basket 9 to a set position. The three-coordinate frame 1 is located above the conveying mechanism and the tobacco box 19. The three-coordinate frame 1 is equipped with a flipping robot, which can move horizontally and vertically on the three-coordinate frame 1, thereby grabbing the tobacco basket 9 and conveying it to the tobacco box 19 for tilting and packing operations. The flipping robot is used to grab the tobacco basket 9 and can drive the tobacco basket 9 to rotate horizontally or flip vertically. By rotating horizontally, the tobacco stems of adjacent two baskets of tobacco leaves can be arranged in an alternating manner, so that the tobacco leaves put into the tobacco box 19 are arranged in an alternating manner, making the overall stacking more neat. At the same time, the two ends of the tobacco box 19 are filled more fully, and the tobacco bags are more square and the packing is more standardized during subsequent packaging.

[0042] The conveying mechanism in this embodiment includes a full-basket conveyor 11 and an empty-basket conveyor 10. The full-basket conveyor 11 can convey tobacco baskets 9 containing tobacco leaves to the bottom of the three-coordinate frame 1, and the empty-basket conveyor 10 can convey empty tobacco baskets 9 into the stacking machine. The full-basket conveyor 11 and the empty-basket conveyor 10 have the same structure, both including a support frame, and a conveyor belt or conveyor roller is installed on the top of the support frame. A single-basket conveyor is provided at the end of the full-basket conveyor 11 away from the three-coordinate frame 1. The single-basket conveyor is equipped with a weighing module, which can weigh a single tobacco basket 9. A lifting conveyor is provided between the single-basket conveyor and the full-basket conveyor 11. The lifting conveyor is used to lift the weighed tobacco basket 9 onto the full-basket conveyor 11. The arrangement of the full-basket conveyor 11 and the empty-basket conveyor 10 is not limited. They can be arranged in parallel, perpendicular, or coaxially end to end.

[0043] To allow the tobacco box 19 to hold more tobacco leaves, this embodiment incorporates a primary pressing robot 12. The primary pressing robot 12 is mounted on a three-coordinate frame 1 and can move horizontally and vertically on the frame. The primary pressing robot 12 uses a primary pressing head 13, with symmetrical pressing bevels 18 on both sides of its top. After the flipping robot pours the tobacco leaves from the tobacco basket 9 into the tobacco box 19, the primary pressing robot 12 moves above the tobacco box 19 to vertically compact the tobacco leaves. The pressing bevels 18 of the primary pressing head 13 are designed to prevent tobacco leaves from remaining on the top of the pressing head; the tobacco leaves fall to the bottom of the box under gravity. Inside the box 19, the initial pressing robot 12 mainly prevents the height of the tobacco leaves inside the box 19 from exceeding the edge of the box 19. In another preferred embodiment, a lateral moving mechanism can also be provided on the bottom surface of the initial pressing head 13. The lateral moving mechanism is provided with a tobacco-pushing pressing head 14. The tobacco-pushing pressing head 14 is used to push the tobacco leaves to both sides of the box 19 to avoid bulging in the middle when the tobacco leaves are packaged. The lateral moving mechanism has the same structure as the lateral moving guide rail pair 2. The design of the tobacco-pushing pressing head 14 relies on the lateral moving guide rail pair 2 to achieve the purpose of pushing the tobacco leaves to both sides, so that the tobacco leaves are arranged at a uniform height in the box 19, avoiding the phenomenon of bulging in the middle when the tobacco leaves are packaged.

[0044] To enable the flipping robot to move the smoke basket 9 to the desired position, this embodiment designs a three-coordinate frame 1, which includes a frame. Two parallel longitudinal moving guide rail pairs 3 are located at the top of the frame. Two transverse moving guide rail pairs 2 slide between the two longitudinal moving guide rail pairs 3. Each transverse moving guide rail pair 2 has a vertical moving guide rail pair 4. One vertical moving guide rail pair 4 has a flipping robot at its bottom, and the other vertical moving guide rail pair 4 has a pre-pressing robot 12 at its bottom. The longitudinal moving guide rail pairs 3, transverse moving guide rail pairs 2, and vertical moving guide rail pairs 4 are driven in the same way. The longitudinal moving guide rail pair 3 includes a longitudinal guide rail, a longitudinal slider that slides on the longitudinal guide rail, and a transverse guide rail connected to the transverse guide rail. A transverse slider is located on the transverse guide rail, a vertical guide rail is located on the transverse slider, a vertical slider is located on the vertical guide rail, and a flipping robot or pre-pressing robot 12 is located on the vertical slider. The driving of each guide rail and corresponding slider adopts a screw-nut pair or a sprocket and chain drive structure, both of which are mature and known transmission methods.

[0045] The flipping robot in this embodiment includes a rotary mechanism 5 connected to the vertical moving guide rail pair 4. The specific structure of the rotary mechanism is not limited; it can employ a rotary screw, rotary gear, or other known technology, and will not be described in detail. In one embodiment, the rotary mechanism 5 includes a rotary frame, on which a rotary motor is mounted. The rotary motor drives a rotary shaft via gear meshing. The rotary shaft at the bottom of the rotary mechanism 5 is connected to a portal frame 6. A flipping mechanism 7 is provided on the inner side of the bottom of the portal frame 6. A locking mechanism 8 is installed at the end of the flipping mechanism 7, and the locking mechanism 8 includes a telescopic cylinder. The two symmetrical locking mechanisms 8 can clamp and fix the sides of the tobacco basket 9 using screw-driven grippers or clamping blocks. The locking mechanism 8 can be fixedly clamped to the side wall of the tobacco basket 9. The flipping mechanism 7 includes a flipping frame set on the side wall of the portal frame 6. The flipping frame is equipped with a horizontally arranged rotating motor. The rotating shaft of the rotating motor is connected to the locking frame. The locking frame is equipped with a locking mechanism 8. The locking mechanism 8 uses a gripper driven by an electric push rod or a gripper driven by a hydraulic cylinder. The grippers on both sides of the portal frame 6 are symmetrically arranged and can be extended and retracted by an electric push rod, so that the grippers can fix and clamp the tobacco basket 9.

[0046] To prevent tobacco leaves from falling off when the tobacco basket 9 is flipped, the locking mechanism 8 in this embodiment is provided with a gantry 16. The gantry 16 is fixed to one side of the locking frame and is a hollow rectangular frame structure. The tobacco basket 9 can be fixedly clamped in the hollow position of the gantry 16. Two symmetrically arranged sealing doors 17 are hinged to the gantry 16 through a rotating shaft. The locking mechanism 8 can fix the tobacco basket 9 in the gantry 16, and the sealing doors 17 can close the opening of the tobacco basket 9. One end of the sealing door 17 is connected to an opening and closing mechanism 15, which can drive the sealing door 17 to open and close. The gantry 16 has strip holes at both ends, and a strip frame is provided at the bottom of the strip holes. An inclined telescopic cylinder is hinged on the strip frame. The end of the cylinder rod of the telescopic cylinder is hinged to the sealing door 17 on the corresponding side, so as to drive the sealing door 17 to open and close. The sealing door 17 protects the tobacco from falling off the tobacco basket 9 during the flipping process. When the tobacco basket 9 is inverted above the tobacco box 19, the sealing door 17 is opened, causing the tobacco leaves in the tobacco basket 9 to fall into the tobacco box 19.

[0047] The present invention also provides an automatic tobacco leaf packing method, comprising the following steps:

[0048] Single cigarette basket weighs 9;

[0049] The lifting conveyor lifts the smoke basket 9 to the full material basket conveyor 11;

[0050] The full-load basket conveyor 11 transports the tobacco basket 9 containing tobacco leaves to the area below the three-coordinate frame 1;

[0051] The flipping robotic arm descends to grab the smoke basket 9, while the smoke sealing door 17 closes the opening of the smoke basket 9;

[0052] The flipping robotic arm lifts the tobacco basket 9, which is then vertically flipped 180 degrees and moved to the tobacco box 19. It then rotates horizontally between boxes, so that the tobacco stems in adjacent baskets are in different positions. This allows the tobacco stems in each basket to be staggered and placed more evenly after the tobacco leaves are poured into the tobacco box 19.

[0053] The robotic arm descends to the opening of the tobacco box 19, opens the sealing door 17, and pours the tobacco leaves into the tobacco box 19;

[0054] The flipping robot lifts the empty tobacco basket 9, which flips 180 degrees and moves to the empty material basket conveyor 10. During this time, the initial pressing robot 12 moves to the tobacco box 19 to perform initial pressing and maneuvering of the tobacco leaves in the tobacco box 19. Then, the initial pressing robot 12 returns to a position away from the tobacco box 19. The initial pressing robot 12 is not a necessary structure, so its position and working time are not limited. It can perform initial pressing and maneuvering of the tobacco leaves in the tobacco box 19 after the flipping mechanism 7 moves away from the tobacco box 19 and before the next tobacco basket 9 is transported above the tobacco box 19.

[0055] The flipping robotic arm descends, dropping the empty smoke basket 9 onto the empty material basket conveyor 10;

[0056] The flipping robotic arm lifts and moves back to its initial position;

[0057] The empty material basket conveyor 10 transports the empty tobacco baskets 9 to the stacking machine 20. The stacking machine 20 is a mature technology and will not be described in detail. By adopting the above method, the present invention can realize the automatic packing of tobacco leaves, and has functions such as automatic weighing, conveying, turning, initial pressing, and empty frame collection, which greatly improves work efficiency.

[0058] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
