Description

Technical Field

[0001] The invention relates to the technical field of cigarette carton processing, in particular to a feeding 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 taken out and the material stacks are placed in a conveying mechanism, which can then convey multiple material stacks to a designated packaging machine for processing to form strip boxes that meet composite requirements.

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

In this embodiment, the wrapping tape is kraft paper. The cutting mechanism can cut the bulge and cut off the wrapping tape, and then automatically remove the wrapping tape. The conveying mechanism conveys the material stack with the cut wrapping tape to the processing equipment, thereby completing the loading of one material stack, and the above process can be repeated for the loading of multiple material stacks. When the feeding device is applied to 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 removed manually, which effectively improves efficiency while reducing the labor intensity of staff, reducing manual participation in the feeding process and improving the degree of automation of feeding. 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 feeding rate.

[0040] Secondly, when the cigarette carton packaging supply line is in use, it can stack large batches of material stacks on the material tray, and the cutting mechanism of the feeding device and the dedicated robot can automatically and orderly transport the material stacks to the loading platform of the feeding device, cut off the wrapping tape of the material stacks, and then send the materials to the packaging machine for processing. The entire feeding process can be completed fully automatically, effectively improving the degree of automation of feeding, reducing the degree of manual participation, and at the same time effectively reducing the possibility of material stacks scattering, and improving the stability and continuity of the feeding process.

In addition, the terms "first" and "second" are only used to distinguish in the description 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 feeding device includes a base 1, a carrying platform 2, a tidying mechanism 3, a paper-feeding mechanism 4, a cutting mechanism 5 and a conveying mechanism 6. The carrying platform 2 is arranged on the base 1 and used to carry a material stack 8; the tidying mechanism 3 is arranged on the base 1 and used to tidy the material stack 8; the paper-feeding mechanism 4 is arranged on the base 1 and used to tidy the material stack 8 and can squeeze the wrapping belt 9 of the material stack 8 to form a bulge; the cutting mechanism 5 is arranged on the base 1 and can cut the bulge to cut off the wrapping belt 9; the conveying mechanism 6 is used to receive the material stack 8 after the wrapping belt 9 is cut off and convey the material stack 8 to the processing equipment.

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

[0069] The tidying mechanism 3 can press against 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 rubbing mechanism 4 can press against 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 into 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 further provided on the outside of the base 1 , and the material tray 14 is used to hold a plurality of material stacks 8 with wrapping tapes 9 ; and the cutting mechanism 5 may be equipped with a dedicated robot 51 , and the robot 51 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, and the suction cup can suck the material stack 8. The cutting mechanism 5 is moved by 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 rubbing 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 continuously, the automatic loading of multiple material stacks 8 can be completed.

[0071] When the feeding device is used, the material stack 8 is first transported to the carrier 2, and the tidying mechanism 3 and the paper rubbing mechanism 4 are operated to tidy the material stack 8 to ensure that the material can be placed in the center of the carrier 2, and then the paper rubbing mechanism 4 rubs the wrapping belt 9 to form a bulge. In this embodiment, the wrapping belt 9 is kraft paper. The cutting mechanism 5 can cut the bulge and cut off the wrapping belt 9, and then automatically remove the wrapping belt 9. The conveying mechanism 6 conveys the material stack 8 with the wrapping belt 9 cut off to the processing equipment, thereby completing the feeding of one material stack 8, and the above process can be repeated for the feeding of multiple material stacks 8. 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 8, which can realize the automatic handling, sorting, cutting and 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 while reducing the labor intensity of the staff, reducing the manual participation in the feeding process, and improving the degree of automation of feeding. 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 feeding 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 tidying mechanism 3 includes a tidying driving member 31 and two tidying plates 32 arranged opposite to each other. The support platform 2 is located between the two tidying plates 32; the tidying driving member 31 is arranged on the base 1 and connected to the two tidying plates 32 to drive the two tidying plates 32 to approach each other so as to abut against the material stack 8 for tidying.

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

[0075] In this embodiment, two slide bars 33 are fixedly arranged on the base 1, and the two slide bars 33 are spaced apart, and the slide bars 33 extend in the direction in which the two regularized plates 32 approach each other. A connecting bar 34 is respectively arranged at both ends of the slide bars 33, and the connecting bar 34 extends in the spacing direction of the two slide bars 33. A slider is arranged on the bottom wall of each connecting bar 34, and the slider is sleeved on the slide bar 33 and slidably connected to the slide bar 33, and the connecting bar 34 is fixedly connected to the corresponding regularized plate 32. A regularized driving member 31 is arranged on one of the two slide bars 33, and the regularized driving member 31 is a cylinder at this time.

[0076] In other embodiments, the regular drive member 31 may also be implemented by other structures, such as a motor and 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 organized, the organizing drive 31 is used to drive the two organizing plates 32 to approach each other, so that the opposite sides of the two organizing plates 32 can gradually approach the opposite sides of the material stack 8. When the organizing plates 32 are pressed against the sides of the material stack 8, both sides of the material stack 8 can be organized to ensure that the material can remain in a centered position between the two organizing plates 32.

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

[0079] Specifically, a plurality of adjusting parts 35 are distributed at intervals on the inner side of the regular plate 32. The adjusting part 35 may be L-shaped, with its vertical arm fixedly connected to the regular plate 32 and its horizontal arm slidably connected to the connecting strip 34. A waist-shaped hole is provided on the horizontal arm, and a bolt is passed through the waist-shaped hole. A bolt hole threadedly connected to the bolt is provided on the connecting strip 34. In this embodiment, two adjusting parts 35 are arranged at intervals.

[0080] By providing the adjustment part 35, the bolts can be loosened to make the tidying plate 32 slide relative to the connecting strip 34, thereby adjusting the distance between the two tidying plates 32, and changing the distance between the two tidying plates 32, so that the tidying mechanism 3 can tidy material stacks 8 of different sizes, effectively improving the adaptability of the two tidying mechanisms 3. In addition, the relative positions of the two tidying plates 32 can also be flexibly adjusted by the adjustment part 35 to ensure that the two tidying plates 32 can remain parallel to the side walls of the material stack 8, and ensure that the tidying plates 32 can smoothly form abutment with the material stack 8 to improve the tidying effect.

[0081] Optionally, the tidying mechanism 3 further includes a pressing portion 36 and a pressing driving member 37. The pressing portion 36 is movably connected to the base 1, and the pressing portion 36 has an avoidance state in which it is dislocated from the supporting platform 2 and a pressing state in which it is opposite to the supporting platform 2 and can press the material stack 8; the pressing driving member 37 is connected to the pressing portion 36 to drive the pressing portion 36 to switch between the pressing state and the avoidance state.

[0082] Specifically, an extension plate 38 is provided on the regular plate 32, and the extension plate 38 extends in a 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 can only drive the pressure portion 36 to extend and retract. 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 driving member 37 adopts a cylinder, and its cylinder body is rotatably connected to the extension plate 38. A separate rotating driving member 66, such as a motor, can be provided to drive the pressing driving member 37 to rotate. A pressing portion 36 is fixedly provided on the piston rod of the pressing driving 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 driving member 37 drives the pressing portion 36 to move downward 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 a 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 vertically, and are fixedly connected to the pressing driving member 37 at the corner where the two intersect. In this way, the pressing portion 36 is formed by two pressing rods. On the one hand, when the pressing portion 36 presses the material stack 8, it can press the material stack 8 at two positions at the same time. On the other hand, it can also reduce the contact area between the pressing portion 36 and the material stack 8, and reduce the possibility of the pressing portion 36 wearing the material. It should be understood that the number of pressing rods is not limited to two, nor is it limited to vertical intersections. It only needs to be able to achieve effective pressing of the material stack 8, and the present invention does not limit this.

[0087] Reference Figures 6 to 8 Optionally, the paper picking mechanism 4 includes a side plate 41, a pressing plate 42, a first driving member 43 and a second driving member 44. The side plate 41 is arranged on the base 1. The pressing plate 42 is arranged opposite to the side plate 41, and the support platform 2 is located between the side plate 41 and the pressing plate 42; the first driving member 43 is connected to the pressing plate 42 to drive the pressing plate 42 to approach the side plate 41 to abut against the wrapping belt 9 of the material stack 8; the second driving member 44 is connected to the first driving member 43 to drive the first driving member 43 to drive the pressing plate 42 to rise so that the wrapping belt 9 forms a bulge to be cut.

[0088] Specifically, the side plate 41 is fixed to the side of the base 1, and a detector can be arranged on the side plate 41 to detect the wrapping belt 9 on the material stack 8. An extrusion plate 42 is arranged opposite to the side plate 41, and the extrusion plate 42 is arranged at the output end of the first driving member 43. The side of the extrusion plate 42 can abut against the material stack 8 to regularize the side of the material stack 8. The first driving member 43 can be a cylinder, and the piston rod of the cylinder is fixedly connected to the extrusion plate 42 to push the extrusion plate 42 close to or away from the material stack 8. The bottom wall of the first driving member 43 is fixedly connected with a first mounting plate 431, and a slide rail can be arranged on the first mounting plate 431. A pull plate 432 is connected to the slide rail through the slide rail. The pull plate 432 is fixedly connected to the extrusion plate 42, so that when the first driving member 43 is actuated to drive the extrusion plate 42 to move, the side of the extrusion plate 42 can remain parallel to the side wall of the material stack 8, so that the extrusion plate 42 can smoothly regularize the material stack 8 and can also smoothly form a tight contact with the wrapping belt 9.

[0089] The base 1 is provided with a second mounting plate 441, which is located below the first mounting plate 431, and the two are slidably connected through a guide column 442 and a guide sleeve. The second driving member 44 is fixed on the second mounting plate 441, and the output end of the second driving member 44 is connected to the first mounting plate 431, and the second driving member 44 can drive the first mounting plate 431 to rise or fall.

[0090] In order to reduce the control difficulty and production cost, the second driving member 44 can be a cylinder, and 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 regulated, the first driving member 43 pushes the extrusion plate 42 close to the material stack 8, and uses the extrusion between the extrusion plate 42 and the material stack 8 to regulate the side of the material stack 8. At the same time, the extrusion plate 42 will squeeze the wrapping belt 9 on the side of the material stack 8. At this time, the second driving member 44 is started, pushing the first driving member 43 and the extrusion plate 42 upward, so as to extrude the wrapping belt 9 upward to form a bulge. The setting of the extrusion plate 42 allows the extrusion plate 42 to form a surface contact with the wrapping belt 9. Compared with the use of rollers and other structures in the prior art to extrude the wrapping belt 9, the extrusion plate 42 has a better paper rubbing effect and is more likely to form a bulge in the wrapping belt 9.

[0092] Optionally, the paper picking 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 the 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 completely correspond to the material stack 8 after being 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 setting the third driving member 45, when the material stack 8 needs to be regularized by the squeezing plate 42, the third driving member 45 and the second driving member 44 can act synchronously, or only the third driving member 45 can be started, so that the squeezing plate 42 is raised to a position corresponding to the material stack 8, and then the first driving member 43 pushes the squeezing plate 42 to form a pressure on the side of the material stack 8 to achieve regularization. When it is necessary to squeeze the wrapping belt 9 to form a bulge, the first driving member 43, the second driving member 44 and the third driving member 45 are first reset, and at this time, the first driving member 43 acts to push the squeezing plate 42 to press against the wrapping belt 9, and the second driving member 44 acts to drive the squeezing plate 42 to move upward, so as to rub the wrapping belt 9 upward to smoothly form a bulge.

[0096] Optionally, a fourth driving member 46 is provided on the first mounting plate 431, and a suction disk 47 is provided at the output end of the fourth driving member 46. The fourth driving member 46 can push the suction disk 47 to abut against the wrapping belt 9, and the suction disk 47 can adsorb the wrapping belt 9. Two fourth driving members 46 can be provided at intervals, and the two fourth driving members 46 are respectively located on both sides of the first driving member 43. A notch is correspondingly provided on the extrusion plate 42 for the suction disk 47 to extend out. The fourth driving member 46 can be a cylinder, or a motor 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 descends under the action of the lifting cylinder, and the fourth driving member 46 drives the suction plate 47 to extend to absorb the wrapping tape 9, and the fourth driving member 46 is 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 being able to quickly pull the wrapping tape 9 out of 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 intersects with the second direction.

[0100] Specifically, the paper picking mechanism 4 and the tidying mechanism 3 respectively press the material stack 8 in two directions to tidy it, so that the tidying effect of the material stack 8 is better and the possibility of the material stack 8 being scattered is reduced. The angle between the first direction and the second direction can be 90° or other degrees, and can be designed according to the shape of the material stack 8 that needs to be tidy, and the present invention does not limit 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 tilted in the width direction, and a belt assembly for conveying the material stack 8 is arranged in 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 tilts 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 sleeved in the conveyor frame 61. A driving motor, a synchronous belt, a tensioning wheel 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 detect whether there is a material stack 8 at the corresponding position, and whether the wrapping belt 9 on the material stack 8 has been disassembled.

[0103] By providing an inclined conveying frame 61, when the material stack 8 from which the wrapping tape 9 is removed is placed on the conveyor belt, the material stack 8 can be made to lean against the side wall of the baffle 62 in an inclined state, and a smooth film can be provided on the side wall of the baffle 62, which can not only reduce the possibility of wear on the material stack 8, but also ensure 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 rotating 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 carrier 2; the rotating 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, a conveying wall is provided on the support frame 67, and the conveying arm 64 can move in the vertical direction and the horizontal direction. The execution end of the conveying arm 64 is hinged to the grabbing head 65, and two opposite grabbing plates 68 are provided on the bottom wall of the grabbing head 65.

In order 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 driving 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 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, and 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 stably placed on the conveyor belt.

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

[0108] When the cigarette carton packaging supply line is in use, it can stack large batches of material stacks 8 at the material tray 14, and the cutting mechanism 5 and the dedicated robot 51 of the feeding device can automatically and orderly transport the material stacks 8 to the loading platform 2 of the feeding device, so as to cut off the wrapping belt 9 of the material stack 8 and then send the material to the packaging machine for processing. The entire feeding process can be completed fully automatically, effectively improving the degree of automation of feeding, reducing the degree of manual participation, 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 position and posture of each structure, and generate a simulation scene without any obstacles or personnel based on the position and 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 also obtain the distance between each structure and the obstacles or personnel in real time, so as to warn 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 combination 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 transported. The material tray 14 filled with the material stack 8 is transported to the designated area by a forklift or other tools. After the intelligent visual safety system can detect that the material stack 8 is in place and there are no obstacles or personnel 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, so as to accurately grab the material stack 8. After grabbing the material stack 8, the robot 51 drives the cutting mechanism 5 to move, so as to transport the material stack 8 containing the wrapping tape 9 to the carrying platform 2.

[0113] Secondly, the material stack 8 is regulated. The regulating drive 31 is actuated, and the two regulating plates 32 are brought close to each other and abutted against the opposite sides of the material stack 8 to regulate 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 part 36 enters the pressing state, and the pressing drive 37 drives the pressing part 36 to move downward, and the pressing part 36 presses the material stack 8; the third driving member 45 and the second driving member 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, and the first driving member 43 is operated to push the squeezing plate 42 close to the material stack 8 to abut against the front side of the material stack 8, so that the three sides of the material stack 8 can be regulated.

[0114] Then, the wrapping belt 9 of the material stack 8 is rubbed. After the material stack 8 is tidied, the first driving member 43, the second driving member 44 and the third driving member 45 are reset, the first driving member 43 is actuated to push the extrusion plate 42 against the wrapping belt 9, the second driving member 44 is actuated to drive the first driving member 43 and the extrusion plate 42 to move upward, and the surface contact between the extrusion plate 42 and the wrapping belt 9 is utilized to ensure that the contact area between the extrusion plate 42 and the wrapping belt 9 is large, so that the wrapping belt 9 can bulge upward to form a bulge as the extrusion plate 42 moves upward.

[0115] The bulge is cut. The cutting blade of the cutting mechanism 5 descends, and after the cutting blade is aligned with the bulge, it 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 adsorbed. The lifting drive member 13 is actuated to drive the carrying platform 2 to descend. At this time, the adsorption plate 47 just corresponds to the cut wrapping tape 9. Then the fourth drive member 46 is actuated to push the adsorption plate 47 to extend to adsorb the cut wrapping tape 9. The fourth drive member 46 is reset to pull the wrapping tape 9 apart. At this time, the adsorption plate 47 stops adsorption again.

[0117] Finally, the paper is pulled out and the material is fed. The suction cup on the cutting mechanism 5 is used to absorb the pulled wrapping tape 9, and the robot 51 drives the cutting mechanism 5 to move to generate a pulling force to pull out the wrapping tape 9 and place it in the recycling box 7 for recycling. The material stack 8 with the wrapping tape 9 cut off is grabbed by the grabbing head 65, and after the angle of the grabbing head 65 is adjusted by the rotating driving member 66, the material stack 8 is placed on the inclined conveying frame 61, and is sent to the packaging machine by the conveyor belt on the conveying frame 61 to complete the 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.
