Description

Technical Field

[0001] The present invention relates to the technical field of cigarette carton processing, in particular to a loading device and a cigarette carton packaging supply line. Background Art

[0002] Cigarette carton paper is usually stacked together during storage and transportation, and then wrapped with wrapping tape such as kraft paper to form a material stack. When the material stack is loaded, the wrapping tape needs to be removed.

[0003] In the prior art, when loading material stacks, the wrapping tape is manually removed and the material stacks are placed in a conveying mechanism, which then conveys the multiple material stacks to a designated packaging machine for processing to form strip boxes meeting composite requirements.

[0004] However, manually removing the wrapping tape from multiple material stacks is not only inefficient and labor-intensive for the staff, but also has a low degree of automation in loading. In addition, manually removing the wrapping tape and then moving the material stacks can easily cause the materials to scatter, resulting in a slower loading speed. Summary of the Invention

[0005] The purpose of the present invention is to provide a loading device and a cigarette box packaging supply line, which not only solves the problems in the prior art of slow efficiency, high labor intensity and low degree of loading automation caused by the need to manually remove multiple wrapping tapes during the material loading process, but also solves the problem that manual removal of the wrapping tapes can easily cause material scattering during the handling of material stacks, resulting in slow material loading speed.

[0015] Two regular plates are arranged opposite to each other, and the supporting platform is located between the two regular plates;

[0016] The arranging driving member is arranged on the base and connected to the two arranging plates to drive the two arranging plates to approach each other so as to abut against the material stack for arranging.

[0017] Optionally, the regularization mechanism further includes:

[0018] a pressing portion movably connected to the base, the pressing portion having an avoidance state in which it is displaced from the supporting platform and a pressing state in which it is opposite to the supporting platform and can press the material stack;

[0019] The pressing driving member is connected to the pressing portion to drive the pressing portion to switch between the pressing state and the avoiding state.

[0020] Optionally, the pressing portion includes two intersecting pressing rods, and the intersection of the two pressing rods is connected to the pressing driving member.

[0021] Optionally, the paper picking mechanism includes:

[0022] a side panel, arranged on the base;

[0023] An extrusion plate is arranged opposite to the side plate, and the bearing platform is located between the side plate and the extrusion plate;

[0024] a first driving member connected to the extrusion plate to drive the extrusion plate to approach the side plate to abut against the wrapping belt of the material stack;

[0025] The second driving member is connected to the first driving member to drive the first driving member to drive the extrusion plate to rise so that the wrapping belt forms a bulge to be cut.

[0026] Optionally, the paper picking mechanism further includes:

[0027] The third driving member is connected to the second driving member to drive the second driving member to rise, so that the extrusion plate can correspond to the material stack.

[0028] Optionally, the paper picking mechanism presses against the material stack along a first direction, and the tidying mechanism presses against the material stack along a second direction, and the first direction intersects with the second direction.

[0029] Optionally, the conveying mechanism includes:

[0030] A conveyor frame, the conveyor frame is tilted along the width direction, and a belt assembly for conveying the material stack is provided in the conveyor frame, one side of the belt assembly corresponds to the base to receive the material stack, and the other side corresponds to the packaging machine to deliver the material stack to the packaging machine;

[0031] The baffle is arranged on a side of the conveying frame that is inclined downward, and the side wall of the baffle can be slidably fitted with the side wall of the material stack.

[0032] Optionally, the conveying mechanism further includes:

[0033] conveyor arm;

[0034] a grabbing head, rotatably connected to the conveying arm and used to grab the material stack on the carrying platform;

[0035] A rotary drive member is connected to the grabbing head to drive the grabbing head to rotate so that the material stack can be placed obliquely on the belt assembly.

[0036] Second, a cigarette carton packaging supply line includes:

[0037] The loading device as described in any one of the first aspects is used to cut the wrapping tapes of multiple material stacks in sequence and then send them to the packaging machine for processing.

[0038] Beneficial effects of the present invention:

[0039] First, when the loading device is in use, the material stack is first moved onto the support platform. The aligning and paper-feeding mechanisms operate to align the material stack, ensuring that it can be placed centrally on the support platform. The paper-feeding mechanism then rolls the wrapping tape (in this embodiment, the wrapping tape is kraft paper) into a bulge. The cutting mechanism then cuts the bulge and severs the wrapping tape, which is then automatically removed. The conveying mechanism then transports the material stack, free of the wrapping tape, to the processing equipment, completing the loading of one material stack. The above process can be repeated for loading multiple material stacks. When the feeding device is used for the fully automatic supply of cigarette packaging box paper, the box paper stack serves as the material stack, which can realize the automatic handling, sorting, cutting, bulging, paper extraction and transportation of large quantities of material stacks. On the one hand, the wrapping tape no longer needs to be manually removed, which effectively improves efficiency while reducing the labor intensity of the staff, reducing the manual participation in the loading process, and improving the degree of automation of loading. On the other hand, because the material stack has been sorted before the wrapping tape is cut, and the material stack can be kept tight during the cutting process, the possibility of material scattering after the wrapping tape is cut is reduced, which is conducive to ensuring that the material stack can be quickly transported to the conveying mechanism for feeding after the wrapping tape is removed, thereby effectively improving the loading rate.

[0040] Secondly, when in use, the cigarette carton packaging supply line can stack large batches of materials on the material tray. The cutting mechanism and dedicated robot of the loading device automatically and orderly transport the material stacks to the loading platform of the loading device, cut the wrapping tape of the material stacks, and then deliver the materials to the packaging machine for processing. This makes the entire loading process fully automatic, effectively improving the degree of automation of loading and reducing the degree of human intervention. It also effectively reduces the possibility of material stacks being scattered, and improves the stability and continuity of the loading process. BRIEF DESCRIPTION OF THE DRAWINGS

These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0066] The embodiment of the invention discloses a loading device and a cigarette carton packaging supply line.

[0067] Reference Figures 1 to 4 The loading device includes a base 1, a supporting platform 2, a sizing mechanism 3, a paper feeding mechanism 4, a cutting mechanism 5, and a conveying mechanism 6. The supporting platform 2 is mounted on the base 1 and is used to support the material stack 8; the sizing mechanism 3 is mounted on the base 1 and is used to sizing the material stack 8; the paper feeding mechanism 4 is mounted on the base 1 and is used to sizing the material stack 8 and is capable of squeezing the wrapping tape 9 of the material stack 8 to form a bulge; the cutting mechanism 5 is mounted on the base 1 and is capable of cutting the bulge to sever the wrapping tape 9; and the conveying mechanism 6 is used to receive the material stack 8 after the wrapping tape 9 is cut and convey the material stack 8 to the processing equipment.

[0068] Specifically, the base 1 is in the shape of a cube. A foot support 11 can be provided at the bottom of the base 1 to secure the base 1 to the bottom surface. Universal wheels 12 can also be provided at locations corresponding to the foot support 11, allowing the base 1 to be moved and conveniently adjusted. A lifting drive 13, such as a cylinder, is provided on the top wall of the base 1. This drive can extend and retract a piston rod in a vertical direction, and the support platform 2 is fixed to the end of the piston rod. The support platform 2 can be in the shape of a cube, specifically a rectangular parallelepiped. In horizontal projection, the cross-sectional area of ​​the support platform 2 is smaller than the cross-sectional area of ​​the material stack 8, so that when the material stack 8 is placed on the support platform 2, the four side walls of the material stack 8 protrude from the support platform 2.

[0069] The tidying mechanism 3 can press the material stack 8 from the two opposite side walls of the material stack 8 to achieve the regularization of the material stack 8, and thus can fix the material stack 8 on the supporting platform 2, while the paper feeding mechanism 4 can press the other side walls of the material stack 8 to further regularize the material stack 8, and at the same time can squeeze the wrapping tape 9 on the material stack 8 and squeeze the wrapping tape 9 upward to form a bulge, and the cutting mechanism 5 can cut off the wrapping tape 9 by cutting off the bulge.

[0070] A material tray 14 may be provided outside the base 1 for holding a plurality of material stacks 8 with wrapping tapes 9 ; and the cutting mechanism 5 may be equipped with a dedicated robot 51 , which is provided between the material tray 14 and the base 1 . In order to further simplify the complexity of the overall loading device structure, the cutting mechanism 5 can have the function of transporting the material stack 8. For example, a suction cup is set on the cutting mechanism 5, which can suck the material stack 8 and move the cutting mechanism 5 through the robot 51 to transport the material stack 8 containing the wrapping tape 9 to the supporting platform 2. At this time, the material stack 8 will be shaped and squeezed by the structuring mechanism 3 and the paper feeding mechanism 4, so that the wrapping tape 9 forms a bulge. After the cutting knife of the cutting mechanism 5 moves to cut off the bulge of the wrapping tape 9, the wrapping tape 9 is extracted by the suction cup and the next material stack 8 is transported. The material stack 8 with the wrapping tape 9 cut off is transported to the processing equipment through the conveying mechanism 6 to complete the loading of a material stack 8. The extracted wrapping tape 9 can be recycled in a recycling box 7 specially set on the outside of the base 1. By repeating the above process, the automatic loading of multiple material stacks 8 can be completed.

[0071] When the loading device is in use, a material stack 8 is first placed on the support platform 2. The aligning mechanism 3 and the paper feeding mechanism 4 operate to straighten the material stack 8, ensuring that the material is placed centrally on the support platform 2. The paper feeding mechanism 4 then rolls the wrapping tape 9 into a bulge. In this embodiment, the wrapping tape 9 is made of kraft paper. The cutting mechanism 5 then cuts the bulge and severs the wrapping tape 9, which is then automatically removed. The conveying mechanism 6 transports the material stack 8, free of the wrapping tape 9, to the processing equipment, thus completing the loading of one material stack 8. The above process can be repeated for loading multiple material stacks 8. When this feeding device is used for the fully automatic supply of cigarette packaging box paper, the box paper stack serves as the material stack 8, which can realize the automatic handling, sorting, cutting, bulging, paper extraction and transportation of large quantities of material stacks 8. On the one hand, the wrapping tape 9 no longer needs to be manually removed, which effectively improves efficiency. At the same time, it can also reduce the labor intensity of the staff, reduce the manual participation in the loading process, and improve the degree of automation of loading. On the other hand, because the material stack 8 has been sorted before the wrapping tape 9 is cut, and the material stack 8 can be kept tight during the cutting process, the possibility of material scattering after the wrapping tape 9 is cut is reduced, which is conducive to ensuring that the material stack 8 can be quickly transported to the conveying mechanism 6 for feeding after the wrapping tape 9 is removed, thereby effectively improving the loading rate.

[0072] Optionally, a camera may be provided on the cutting mechanism 5 , and the camera may be equipped with a corresponding identification system for accurately identifying and locating the material stack 8 , so that the cutting mechanism 5 can automatically complete the handling of the material stack 8 .

[0073] Reference Figure 4 and Figure 5 Optionally, the arranging mechanism 3 includes an arranging drive 31 and two arranging plates 32 disposed opposite each other. The supporting platform 2 is located between the two arranging plates 32. The arranging drive 31 is disposed on the base 1 and connected to the two arranging plates 32 to drive the two arranging plates 32 to approach each other so as to abut against the material stack 8 for arranging.

[0074] Specifically, the structuring plate 32 is a thin plate extending in the vertical direction. A smooth film can be provided on the inner side of the structuring plate 32 so that the inner side does not abrade the material when it abuts against the material stack 8. The structuring plate 32 is slidably connected to the base 1. The sliding connection can be achieved by a slide rail or by a slider and a slide rod 33.

[0075] In this embodiment, two slide bars 33 are fixedly mounted on the base 1 and spaced apart. The slide bars 33 extend in the direction in which the two structured plates 32 approach each other. A connecting bar 34 is provided at each end of the slide bars 33. The connecting bar 34 extends in the direction of the spacing between the two slide bars 33. A slider is provided on the bottom wall of each connecting bar 34. The slider is sleeved on the slide bar 33 and slidably connected to the slide bar 33, while the connecting bar 34 is fixedly connected to the corresponding structured plate 32. A structured driving member 31 is provided on one of the two slide bars 33. In this case, the structured driving member 31 is a cylinder.

[0076] In other embodiments, the regular drive member 31 may also be implemented using other structures, such as a motor combined with a lead screw, etc. The present invention does not limit the specific type of the regular drive member 31.

[0077] When the material stack 8 is being straightened, the straightening drive 31 is used to drive the two straightening plates 32 to approach each other, so that the opposite sides of the two straightening plates 32 can gradually approach the opposite sides of the material stack 8. When the straightening plates 32 are pressed against the sides of the material stack 8, both sides of the material stack 8 can be straightened to ensure that the material can maintain a centered position between the two straightening plates 32.

[0078] Optionally, in order to improve the adaptability of the tidying mechanism 3 , the tidying plate 32 and the connecting bar 34 can be slidably connected.

[0079] Specifically, multiple adjustment portions 35 are spaced apart on the inner side of the regularized plate 32. The adjustment portion 35 may be L-shaped, with its vertical arm fixedly connected to the regularized plate 32 and its horizontal arm slidably connected to the connecting bar 34. The horizontal arm is provided with a waist-shaped hole through which a bolt is passed. The connecting bar 34 is provided with a bolt hole threadedly connected to the bolt. In this embodiment, two adjustment portions 35 are provided at intervals.

[0080] By providing the adjustment portion 35, the structuring plates 32 can be slid relative to the connecting strips 34 by loosening the bolts, thereby adjusting the spacing between the two structuring plates 32. This allows the structuring mechanism 3 to structurize material stacks 8 of different sizes, effectively improving the adaptability of the two structuring mechanisms 3. Furthermore, the relative positions of the two structuring plates 32 can be flexibly adjusted by the adjustment portion 35 to ensure that the two structuring plates 32 remain parallel to the sidewalls of the material stack 8 and that the structuring plates 32 can smoothly abut against the material stack 8, thereby improving the structuring effect.

[0081] Optionally, the tidying mechanism 3 further includes a pressing portion 36 and a pressing drive 37. The pressing portion 36 is movably connected to the base 1 and has a reciprocating state in which it is offset from the support platform 2 and a pressing state in which it is opposite to the support platform 2 and can press against the material stack 8. The pressing drive 37 is connected to the pressing portion 36 to drive the pressing portion 36 to switch between the reciprocating state and the reciprocating state.

[0082] Specifically, an extension plate 38 is provided on the regular plate 32, and the extension plate 38 extends in the horizontal direction. A pressure driving member 37 is provided on the top wall of the extension plate 38, and a pressure portion 36 is provided at the output end of the pressure driving member 37. The pressure driving member 37 can drive the pressure portion 36 to rotate and extend, or it can only drive the pressure portion 36 to extend and extend. The pressure driving member 37 itself can be rotatably connected to the extension plate 38 to drive the pressure portion 36 to rotate through its own rotation.

[0083] In this embodiment, the pressing drive member 37 adopts a cylinder, and its cylinder body is rotatably connected to the extension plate 38. A separate rotating drive member 66, such as a motor, can be provided to drive the pressing drive member 37 to rotate. A pressing portion 36 is fixedly provided on the piston rod of the pressing drive member 37. The pressing portion 36 can rotate when the regular plate 32 is pressed against the material stack 8 to enter the pressing state from the avoidance state, and then the pressing portion 36 is driven downward by the pressing drive member 37 so that the pressing portion 36 is pressed against the material stack 8 to compress the material and maintain the pressing state.

[0084] By providing the pressing portion 36 and the pressing driving member 37, when the material stack 8 is placed on the supporting platform 2 or taken out from the supporting platform 2, the pressing portion 36 can be switched to an avoidance state to avoid interference between the pressing portion 36 and the material stack 8. When the material stack 8 containing the wrapping tape 9 is placed on the supporting platform 2, while the material stack 8 is being tidied, the pressing portion 36 can be driven by the pressing driving member 37 to enter the pressing state, and the pressing driving member 37 then drives the pressing portion 36 close to the top of the material stack 8. When the pressing portion 36 is pressed against the material stack 8, the pressing driving member 37 can lock the pressing portion 36 so that the pressing portion 36 remains in the pressing state, thereby fixing the material stack 8.

[0085] Optionally, the pressing portion 36 includes two intersecting pressing rods, and the intersection of the two pressing rods is connected to the pressing driving member 37 .

[0086] Specifically, the two pressing rods can intersect perpendicularly and be fixedly connected to the pressing drive member 37 at the corner where they intersect. Forming the pressing portion 36 with the two pressing rods in this manner allows the pressing portion 36 to press the material stack 8 simultaneously at two locations. Furthermore, the contact area between the pressing portion 36 and the material stack 8 can be reduced, thereby reducing the possibility of the pressing portion 36 abrading the material. It should be understood that the number of pressing rods is not limited to two, nor is it limited to perpendicular intersections. As long as they can effectively press the material stack 8, the present invention is not limited thereto.

[0087] Reference Figures 6 to 8 Optionally, the paper pickup mechanism 4 includes a side plate 41, a squeeze plate 42, a first drive member 43, and a second drive member 44. The side plate 41 is disposed on the base 1. The squeeze plate 42 is disposed opposite the side plate 41, with the support platform 2 located between the side plate 41 and the squeeze plate 42. The first drive member 43 is connected to the squeeze plate 42 to drive the squeeze plate 42 toward the side plate 41 to abut the wrapping belt 9 of the material stack 8. The second drive member 44 is connected to the first drive member 43 to drive the first drive member 43 to raise the squeeze plate 42, so that the wrapping belt 9 forms a bulge to be cut.

[0088] Specifically, a side plate 41 is fixed to the side of the base 1. A detector can be provided on the side plate 41 to detect the wrapping tape 9 on the material stack 8. A squeeze plate 42 is provided opposite the side plate 41. The squeeze plate 42 is positioned at the output end of a first drive member 43. The side of the squeeze plate 42 can abut against the material stack 8 to straighten the side of the material stack 8. The first drive member 43 can be a pneumatic cylinder, the piston rod of which is fixedly connected to the squeeze plate 42 to push the squeeze plate 42 toward or away from the material stack 8. A first mounting plate 431 is fixedly connected to the bottom wall of the first drive member 43. A slide rail can be provided on the first mounting plate 431, and a pull plate 432 is connected to the slide rail via the slide rail. The pull plate 432 is fixedly connected to the squeeze plate 42. When the first drive member 43 is actuated to move the squeeze plate 42, the side of the squeeze plate 42 remains parallel to the side wall of the material stack 8. This allows the squeeze plate 42 to smoothly straighten the material stack 8 and form a tight contact with the wrapping tape 9.

[0089] A second mounting plate 441 is provided on the base 1 and is positioned below the first mounting plate 431. The two are slidably connected via guide posts 442 and guide sleeves. A second driver 44 is secured to the second mounting plate 441. The output end of the second driver 44 is connected to the first mounting plate 431, enabling the second driver 44 to raise or lower the first mounting plate 431.

[0090] In order to reduce the control difficulty and production cost, the second driving member 44 can be a cylinder, and similarly the first driving member 43 can also be a cylinder. If the control accuracy of the moving distance needs to be improved, the first driving member 43 and the second driving member 44 can both be composed of a motor and a screw.

[0091] When the material stack 8 is being straightened, the first driving member 43 pushes the extrusion plate 42 toward the material stack 8, creating an extrusion between the extrusion plate 42 and the material stack 8, thereby straightening the side of the material stack 8. At the same time, the extrusion plate 42 presses the wrapping tape 9 against the side of the material stack 8. At this time, the second driving member 44 is activated, pushing the first driving member 43 and the extrusion plate 42 upward, thereby squeezing the wrapping tape 9 upward and bulging it. The arrangement of the extrusion plate 42 creates surface contact between the extrusion plate 42 and the wrapping tape 9. Compared to the conventional method of using rollers or other structures to squeeze the wrapping tape 9, the extrusion plate 42 has a better paper-rubbing effect and is more likely to cause the wrapping tape 9 to bulge.

[0092] Optionally, the paper pickup mechanism 4 further includes a third driving member 45 . The third driving member 45 is connected to the second driving member 44 to drive the second driving member 44 to rise, so that the pressing plate 42 can correspond to the material stack 8 .

[0093] Specifically, the second driving member 44 is only moved to roll up the wrapping belt 9, so its stroke is small. When the material stack 8 is regularized by the extrusion plate 42, it is necessary to ensure that the extrusion plate 42 can completely correspond to the material stack 8. Therefore, a third mounting plate 451 is provided on the base 1, and a third driving member 45 is fixedly provided on the third mounting plate 451. The output end of the third driving member 45 is connected to the second mounting plate 441 to drive the second mounting plate 441 to rise or fall, thereby pushing the extrusion plate 42 to rise and fall.

[0094] The stroke of the third driving member 45 is greater than the stroke of the second driving member 44 to ensure that the extrusion plate 42 can be completely aligned with the material stack 8 after it is raised. In this embodiment, the third driving member 45 can also be implemented by a cylinder. In other embodiments, the third driving member 45 can also be implemented by a motor and a screw.

[0095] By providing the third drive member 45, when the material stack 8 needs to be straightened by the squeezing plate 42, the third drive member 45 and the second drive member 44 can be activated synchronously, or only the third drive member 45 can be activated, so that the squeezing plate 42 is raised to a position corresponding to the material stack 8. Then, when the first drive member 43 pushes the squeezing plate 42, it can press against the side of the material stack 8 to achieve straightening. When it is necessary to squeeze the wrapping tape 9 to form a bulge, the first drive member 43, the second drive member 44, and the third drive member 45 are first reset. At this time, the first drive member 43 is activated to push the squeezing plate 42 against the wrapping tape 9, and the second drive member 44 is activated to drive the squeezing plate 42 upward, thereby rubbing the wrapping tape 9 upward and smoothly forming a bulge.

[0096] Optionally, a fourth drive member 46 is provided on the first mounting plate 431. A suction disc 47 is provided at the output end of the fourth drive member 46. The fourth drive member 46 can push the suction disc 47 into contact with the wrapping tape 9, thereby attracting the wrapping tape 9. Two fourth drive members 46 can be provided at intervals, one on each side of the first drive member 43. A corresponding notch is provided on the extrusion plate 42 to allow the suction disc 47 to extend. The fourth drive member 46 can be a cylinder or a motor in conjunction with a screw.

[0097] By providing the fourth driving member 46 and the suction plate 47, after the wrapping tape 9 is cut, the supporting platform 2 is lowered by the action of the lifting cylinder. At this time, the fourth driving member 46 drives the suction plate 47 to extend to absorb the wrapping tape 9. The fourth driving member 46 is then reset to pull the wrapping tape 9 away from the material stack 8, so that the suction cup on the cutting mechanism 5 can absorb the wrapping tape 9, thereby quickly pulling the wrapping tape 9 out from the material stack 8.

[0098] Optionally, a protective cover 48 may be provided on the outer side of the paper pickup mechanism 4 , and the protective cover 48 may cover the first mounting plate 431 , the second mounting plate 441 and the third mounting plate 451 at the same time.

[0099] Optionally, the paper picking mechanism 4 is pressed against the material stack 8 along a first direction, and the tidying mechanism 3 is pressed against the material stack 8 along a second direction, and the first direction and the second direction intersect.

[0100] Specifically, the paper feeding mechanism 4 and the aligning mechanism 3 respectively press against the material stack 8 in two directions to align the material stack 8, thereby achieving a better aligning effect on the material stack 8 and reducing the possibility of the material stack 8 being scattered. The angle between the first direction and the second direction can be 90° or other degrees. The specific design can be based on the actual shape of the material stack 8 to be aligned, and the present invention is not limited to this.

[0101] Reference Figures 9 to 11Optionally, the conveying mechanism 6 includes a conveying frame 61 and a baffle 62. The conveying frame 61 is arranged obliquely along the width direction. A belt assembly for conveying the material stack 8 is arranged inside the conveying frame 61. One side of the belt assembly corresponds to the base 1 to receive the material stack 8, and the other side corresponds to the packaging machine to deliver the material stack 8 to the packaging machine. The baffle 62 is arranged on the side of the conveying frame 61 that is inclined downward, and the side wall of the baffle 62 can slide and fit with the side wall of the material stack 8.

[0102] Specifically, the conveyor frame 61 extends obliquely along the width direction so that the conveyor frame 61 forms a layout with one side high and the other side low along the width direction. A baffle 62 is provided on the lower side. The belt assembly includes a conveyor belt arranged in the conveyor frame 61. A drive motor, a synchronous belt, a tensioning pulley and other structures are provided in the conveyor frame 61 to drive the conveyor belt to move. A plurality of photoelectric switches 63 can be provided on the conveyor frame 61 to facilitate the corresponding detection of whether there is a material stack 8 at the corresponding position, and to detect whether the wrapping belt 9 on the material stack 8 has been disassembled.

[0103] By setting up an inclined conveyor frame 61, when the material stack 8 with the wrapping belt 9 removed is placed on the conveyor belt, the material stack 8 can be tilted and lean against the side wall of the baffle 62. A smooth film can be set on the side wall of the baffle 62, which not only reduces the possibility of wear on the material stack 8, but also ensures that the material stack 8 is effectively limited to reduce the possibility of scattering of the material stack 8.

[0104] Optionally, the conveying mechanism 6 includes a conveying arm 64, a grabbing head 65, and a rotary drive 66. The grabbing head 65 is rotatably connected to the conveying arm 64 and is used to grab the material stack 8 on the supporting platform 2; the rotary drive 66 is connected to the grabbing head 65 to drive the grabbing head 65 to rotate so that the material stack 8 can be tilted and placed on the belt assembly.

[0105] Specifically, a support frame 67 is provided on the base 1, and a conveying wall is provided on the support frame 67. The conveying arm 64 can move in the vertical and horizontal directions. The execution end of the conveying arm 64 is hinged to the grabbing head 65. The bottom wall of the grabbing head 65 is provided with two opposing grabbing plates 68. A cylinder is provided on the grabbing head 65 to drive the two grabbing plates 68 to move and grab a group of material stacks 8. To ensure the stability of the grabbing, a load hook 69 can also be provided on the lower side of the grabbing plate 68. The rotating drive member 66 can use a motor to drive the grabbing head 65 to rotate. The motor can be a reduction motor or a servo motor equipped with a reducer.

[0106] By setting up the conveying wall, the grabbing head 65 can move flexibly. When it is necessary to transport the material stack 8, the conveying wall is used to drive the grabbing head 65 close to the material stack 8. The grabbing head 65 can use the cylinder and the grabbing plate 68 to grab the material stack 8. After grabbing the material stack 8, the rotating motor can be started to drive the grabbing head 65 to rotate, so that the bottom surface of the material stack 8 can be parallel to the top wall of the conveyor belt, so that the material stack 8 can be placed stably on the conveyor belt.

[0107] The cigarette carton packaging supply line includes a loading device as described in the above embodiment, which is used to sequentially cut the wrapping bands 9 of multiple material stacks 8 on the material tray 14 and deliver them to the packaging machine for processing.

[0108] When in use, the cigarette carton packaging supply line can stack large batches of material stacks 8 on the material tray 14. The cutting mechanism 5 and the dedicated robot 51 of the loading device can automatically and orderly transport the material stacks 8 to the loading device's support platform 2, cut the wrapping bands 9 of the material stacks 8, and then deliver the materials to the packaging machine for processing. This allows the entire loading process to be completed fully automatically, effectively improving the degree of automation of loading, reducing the degree of human intervention, and helping to improve the overall production efficiency of the cigarette carton packaging supply line.

[0109] Optionally, an intelligent visual safety system can be set up on the cigarette carton packaging supply line, that is, a depth camera is set up on the cigarette carton packaging supply line to collect the scene point cloud of the wire trough, and communicate with each structure in the cigarette carton packaging supply line to obtain the posture of each structure, and generate a simulation scene without any obstacles or personnel based on the posture, and then input the actual scene and the simulation deposition into the neural network. The 3D visual point cloud segmentation system formed by the deep learning neural network and the depth camera can accurately identify the scene of the wire trough, and monitor in real time whether there are obstacles or personnel in the area of ​​the cigarette carton packaging supply line, and can obtain the distance between each structure and the obstacles or personnel in real time, so as to give early warning of possible accidents or slow down or even stop the movement of each structure, so as to improve the safety protection performance of the entire supply line.

[0110] The specific principle of the feeding device is described below in conjunction with the overall structure of this embodiment:

[0111] The feeding device is used for the automatic feeding of carton paper stacks (hereinafter referred to as material stacks 8) in a cigarette carton packaging supply line.

[0112] First, the material stack 8 containing the wrapping tape 9 is moved. A forklift or other tool is used to move the material tray 14 filled with the material stack 8 to the designated area. After the intelligent visual safety system detects that the material stack 8 is in place and there are no obstacles or human interference, it controls the robot 51 of the cutting mechanism 5 to move the cutting mechanism 5 above the material stack 8. The camera on the cutting mechanism 5 can identify and locate the material stack 8, thereby accurately grasping the material stack 8. After grasping the material stack 8, the robot 51 drives the cutting mechanism 5 to move, so as to move the material stack 8 containing the wrapping tape 9 to the supporting platform 2.

[0113] Next, the material stack 8 is straightened. The straightening drive 31 is actuated, and the two straightening plates 32 approach each other and abut against opposite sides of the material stack 8 to straighten the material stack 8, so that the material stack 8 is fixed in the center on the supporting platform 2; the pressing drive 37 rotates, and the pressing portion 36 enters the pressing state, and the pressing drive 37 drives the pressing portion 36 downward, and the pressing portion 36 presses the material stack 8; the third drive 45 and the second drive 44 are actuated in sequence to move the squeezing plate 42 to the highest position, ensuring that the squeezing plate 42 corresponds to the material stack 8. The first drive 43 is operated, pushing the squeezing plate 42 close to the material stack 8 to abut against the front side of the material stack 8, thus completing the straightening of the three sides of the material stack 8.

[0114] Then, the wrapping belt 9 of the material stack 8 is rubbed. After the material stack 8 is straightened, the first driving member 43, the second driving member 44, and the third driving member 45 are reset. The first driving member 43 is activated to push the extrusion plate 42 against the wrapping belt 9. The second driving member 44 is activated to drive the first driving member 43 and the extrusion plate 42 upward. The surface contact between the extrusion plate 42 and the wrapping belt 9 ensures a large contact area between the extrusion plate 42 and the wrapping belt 9. As the extrusion plate 42 moves upward, the wrapping belt 9 bulges upward to form a bulge.

[0115] Then the bulge is cut. The cutting blade of the cutting mechanism 5 descends, and after the bulge is aligned, the cutting blade cross-cuts the bulge, thereby cutting off the bulge of the wrapping belt 9, and the first driving member 43 and the second driving member 44 are reset.

[0116] Then, the wrapping tape 9 is sucked in. The lifting drive member 13 is actuated, driving the supporting platform 2 to descend. At this time, the suction plate 47 is exactly aligned with the cut wrapping tape 9. The fourth drive member 46 is actuated, pushing the suction plate 47 out to suck in the cut wrapping tape 9. The fourth drive member 46 is reset, thereby pulling the wrapping tape 9 apart. At this time, the suction plate 47 stops sucking.

[0117] Finally, the paper is drawn and fed. The suction cup on the cutting mechanism 5 attracts the stretched wrapping tape 9, and the robot 51 drives the cutting mechanism 5 to move, generating a pulling force that pulls the wrapping tape 9 out and places it in the recycling bin 7 for recycling. The material stack 8 from which the wrapping tape 9 has been cut is then grabbed by the gripping head 65. After the angle of the gripping head 65 is adjusted by the rotating drive 66, the material stack 8 is placed on the inclined conveyor frame 61, which then conveys it to the packaging machine via the conveyor belt on the conveyor frame 61 for loading.

[0118] At this point, the fully automatic loading of one material stack 8 is completed, and the cutting mechanism 5 continues to transport the next material stack 8 to carry out the next cycle, thereby realizing the fully automatic supply of batch material stacks 8.

[0119] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
