Description

Technical Field

[0001] The present invention relates to the technical field of corrugated cardboard production, and particularly to an automated conveying device and method for producing V-shaped deep-corrugated high-strength corrugated cardboard. Background Art

[0002] ‌‌V-shaped corrugated cardboard is a type of corrugated cardboard, and its core feature is that its corrugated waveform presents a sharp triangular structure, with a sharp corrugated top (the top of the corrugation) and a gentle corrugated valley (the connection between adjacent corrugations). This design achieves high compressive performance through the triangular mechanics principle (the resultant force of the two hypotenuses supports the external force), and at the same time, due to the small contact area between the corrugated top and the face paper, the usage of adhesives and base paper is reduced.

[0003] When producing V-shaped corrugated cardboard, a conveying device is used for its conveyance. The Chinese patent with the publication number CN118744914A discloses a conveying device for a corrugated cardboard production line, including: a conveying mechanism is arranged on the upper side of a conveying table, a stacking mechanism is arranged on the upper side of a bottom plate, and a pushing mechanism is arranged at the rear of the stacking mechanism; through the cooperation of the conveying mechanism and the stacking mechanism, the present invention can continuously and uninterruptedly convey corrugated cardboard while synchronously stacking and arranging it. This operation method not only greatly shortens the overall time consumed for the conveyance and stacking processing of corrugated cardboard, but also greatly improves the continuity and efficiency of the overall operation process; according to the relatively light weight characteristic of corrugated cardboard, through the cooperation of the stacking mechanism and the pushing mechanism, the corrugated cardboard can be stacked and arranged by continuously inserting it from bottom to top. However, when multiple layers of corrugated cardboard are stacked, the weight of multiple corrugated cardboard sheets will press on the bottommost corrugated cardboard. At this time, when stacking and arranging corrugated cardboard by continuously inserting it from bottom to top, when the stacked corrugated cardboard is lifted, one end of the bottommost corrugated cardboard in contact with the conveyor belt bears the weight of all the corrugated cardboard sheets above it, thereby causing damage to the corrugated cardboard.

[0004] In view of this, the present invention proposes an automated conveying device and method for producing V-shaped deep-corrugated high-strength corrugated cardboard to solve the problems existing in the above-mentioned prior art. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose an automated conveying device and method for producing V-shaped deep-corrugated high-strength corrugated cardboard.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions: An automated conveying device for producing a V-shaped deep-corrugated high-strength corrugated cardboard, comprising a driving mechanism and a conveyor belt for conveying the corrugated cardboard. Two grooves are symmetrically arranged on the conveyor belt, and through openings are provided on the grooves. A pair of second fixing plates are fixedly connected in each of the two grooves, and a rotating cylinder is rotatably connected between each pair of second fixing plates. A concave cam is arranged at the axis of the rotating cylinder, and first fixing plates are fixedly connected to both ends of the concave cam. The first fixing plates are fixedly connected to the inner wall of the groove, and L-shaped baffles are arranged on one side of each of the two grooves. Pressure sensors are symmetrically arranged on the outer wall of the L-shaped baffle facing the corrugated cardboard. The driving mechanism can rotate the rotating cylinder, and a plurality of lifting mechanisms are symmetrically and equidistantly arranged on the rotating cylinder; The lifting mechanism includes an L-shaped lifting plate. The L-shaped lifting plate is slidably connected to the rotating cylinder, and a plurality of balls are equidistantly arranged at one end of the L-shaped lifting plate facing the concave cam. The balls are in contact with the outer wall of the concave cam. L-shaped grooves are formed at the other ends of the L-shaped lifting plates, and a plurality of rollers are rotatably connected at equal intervals inside the L-shaped grooves.

[0007] Furthermore, the driving mechanism includes a driving motor, a first transmission wheel, a transmission belt, and a second transmission wheel. The driving motor is arranged on the outer wall of one side of the through opening. The first transmission wheel is fixedly connected to the outer wall of the rotating cylinder. The second transmission wheel is arranged at the output shaft end of the driving motor. The transmission belt passes through the through opening and is sleeved on the outer walls of the first transmission wheel and the second transmission wheel.

[0008] Furthermore, through grooves are formed at the upper ends of the L-shaped baffles, and sliding grooves are formed on both inner walls of the through grooves. An electromagnet is arranged on the inner wall of the bottom of the through groove, and a magnetic steel is slidably connected to the inner wall of the sliding groove.

[0009] Furthermore, the magnetic force generated after the electromagnet is energized repels the magnetic steel, and a connecting spring is fixedly connected between the electromagnet and the magnetic steel. A telescopic baffle is fixedly connected to the top of the magnetic steel, and the width of the telescopic baffle is the same as the width of the L-shaped baffle.

[0010] Furthermore, hydraulic rods are arranged on the outer walls of the tops of the two grooves, and mounting plates are fixedly connected to the telescopic ends of the hydraulic rods. Two rotating columns are symmetrically and rotatably connected to the lower ends of the mounting plates, and swing plates are fixedly connected to one ends of the two rotating columns.

[0011] Furthermore, a first gear is fixedly connected to the outer walls of the two rotating columns, and the two first gears are meshed. A first servo motor is arranged at the other end of one of the rotating columns.

[0012] Furthermore, on the other sides of the two grooves, there are fixed plates III respectively, and driving shafts are rotatably connected to the outer walls of the fixed plates III. On one side of each fixed plate III, there is a servo motor II, and a gear II is fixedly connected to the output shaft end of the servo motor II. On the top ends of the two driving shafts, gears III are fixedly connected respectively, and the gear III meshes with the corresponding gear II.

[0013] Furthermore, fixed sleeves are fixedly connected to the outer walls at the bottoms of the fixed plates III respectively, and the central axes of the fixed sleeves coincide with the central axes of the driving shafts. At the bottom ends of the two driving shafts, a deviation rectifying column I and a deviation rectifying column II with the same diameter are fixedly connected respectively. The outer diameter of the fixed sleeve is the same as the diameters of the deviation rectifying column I and the deviation rectifying column II, and a plurality of infrared sensors are equidistantly arranged on the outer wall of the fixed sleeve.

[0014] A conveying method for an automatic conveying device for producing V-shaped deep-corrugated high-strength corrugated cardboard includes the following steps: S1. The conveyor belt moves a plurality of corrugated cardboard arranged at intervals above it, and the deviation rectifying column I and the deviation rectifying column II can rectify the deviated corrugated cardboard. S2. When the rectified corrugated cardboard contacts the pressure sensor on the L-shaped baffle, the driving mechanism rotates the rotating cylinder, and through the lifting mechanism, the corrugated cardboard can be lifted. After lifting, then the next corrugated cardboard is made to enter the gap of the lifted corrugated cardboard, and the above operations are cycled. Thus, through the plurality of lifting mechanisms on the outer wall of the rotating cylinder, the corrugated cardboard can be continuously stacked from top to bottom. S3. And when stacking the corrugated cardboard, the hydraulic rods make the two swing plates on the mounting plate approach the outer wall of the corrugated cardboard, and can simultaneously press both ends of the stacked corrugated cardboard, making the stacked corrugated cardboard flat.

[0015] The beneficial effects of the present invention are as follows: 1. The present invention can automatically lift the corrugated cardboard on the conveyor belt, then make the next corrugated cardboard enter the gap of the lifted corrugated cardboard, and then lift the corrugated cardboard again. Thus, during the conveying process of the corrugated cardboard, the corrugated cardboard can be continuously stacked from top to bottom, greatly improving the stacking efficiency.

[0016] 2. Through the L-shaped baffle, the present invention can limit the corrugated cardboard on the conveyor belt, facilitating its lifting, and can adjust the length of the telescopic baffle extending out of the through groove to adapt to different stacking heights, and can limit one side of the stacked corrugated cardboard, so that the stacked corrugated cardboard becomes stable during the lifting process and avoids tilting.

[0017] 3. Through the cooperation of the hydraulic rods and the swing plates, the present invention can simultaneously press both ends of the stacked corrugated cardboard, making the stacked corrugated cardboard flat and avoiding deformation of the corrugated cardboard due to uneven stress during stacking.

[0018] 4. The present invention can correct the inclination of the corrugated cardboard on the conveyor belt through the first deviation-correcting column and the second deviation-correcting column, facilitating the subsequent stacking work. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0021] The technical solution of the present invention will be further described in detail below in conjunction with the specific implementation manners.

[0022] Example 1: Refer to Figures 1-5 , an automatic conveying device for producing V-shaped deep-ridged high-strength corrugated cardboard, including a driving mechanism and a conveyor belt 1 for conveying corrugated cardboard. Two grooves are symmetrically arranged on the conveyor belt 1, and through ports 2 are arranged on the grooves. A pair of fixing plates two 7 are fixedly connected in each of the two grooves, and a rotating cylinder 5 is rotatably connected between each pair of fixing plates two 7. A concave cam 15 is arranged at the axis of the rotating cylinder 5, and fixing plates one 6 are fixedly connected to both ends of the concave cam 15. The fixing plates one 6 are fixedly connected to the inner wall of the groove. L-shaped baffles 4 are arranged on one side of the two grooves, and pressure sensors 16 are symmetrically arranged on the outer wall of the L-shaped baffle 4 facing the corrugated cardboard. The driving mechanism can make the rotating cylinder 5 rotate, and a plurality of lifting mechanisms are symmetrically and equidistantly arranged on the rotating cylinder 5; The lifting mechanism includes an L-shaped lifting plate 13. The L-shaped lifting plate 13 is slidably connected to the rotating cylinder 5. A plurality of ball bearings 14 are equidistantly arranged at one end of the L-shaped lifting plate 13 facing the concave cam 15. The ball bearings 14 are in contact with the outer wall of the concave cam 15. L-shaped grooves 8 are formed at the other ends of the L-shaped lifting plate 13. A plurality of rollers 9 are rotatably connected to the L-shaped grooves 8 at equal intervals. A plurality of corrugated papers are placed on the conveyor belt 1, and there are gaps between adjacent corrugated papers. The conveyor belt 1 can move the corrugated papers arranged with these gaps. When a corrugated paper contacts the pressure sensor 16 on the L-shaped baffle 4, at this time, the corrugated paper is located between two L-shaped lifting plates 13. Because the conveyor belt 1 moves the corrugated paper, and the L-shaped baffle 4 can block the movement of the corrugated paper, the pressure sensor 16 can generate a pressure signal, and the generated pressure signal can be received by an external controller. When the external controller receives this pressure signal, the driving mechanism is started, causing the rotating cylinder 5 to rotate rapidly. During this process, the rollers 9 on the L-shaped lifting plate 13 below the corrugated paper will contact it. As the rotating cylinder 5 rotates, a plurality of rollers 9 on the L-shaped lifting plate 13 will contact the bottom of the corrugated paper above it until the plurality of rollers 9 of the L-shaped lifting plate 13 are parallel to the horizontal plane. Then the driving mechanism stops operating, and the rotating cylinder 5 no longer rotates. And because there are gaps between adjacent corrugated papers, during the process of lifting the corrugated paper, the next corrugated paper will not enter below the lifted corrugated paper. Only after the corrugated paper is lifted and the driving mechanism stops operating, will the next corrugated paper gradually enter the gap between the L-shaped lifting plate 13 below the lifted corrugated paper and the L-shaped lifting plate 13 adjacent to the L-shaped lifting plate 13 and below the next corrugated paper. By repeating the above operations, it is possible to stack and place the corrugated papers synchronously while continuously conveying the corrugated papers, improving the stacking efficiency. When the stacking is completed, the stacked corrugated papers are transferred away by an external gripping robot.

[0023] As a further solution in the present invention, the driving mechanism includes a driving motor 3, a first transmission wheel 10, a transmission belt 11, and a second transmission wheel 12. The driving motor 3 is arranged on the outer wall of one side of the through port 2. The first transmission wheel 10 is fixedly connected to the outer wall of the rotating cylinder 5. The second transmission wheel 12 is arranged at the output shaft end of the driving motor 3. The transmission belt 11 passes through the through port 2 and is sleeved on the outer walls of the first transmission wheel 10 and the second transmission wheel 12. The driving motor 3 can make the second transmission wheel 12 on its output shaft end rotate. Because the transmission belt 11 is sleeved between the second transmission wheel 12 at the output shaft end of the driving motor 3 and the first transmission wheel 10 on the outer wall of the rotating cylinder 5, the rotating cylinder 5 can be rotated.

[0024] As a further solution in the present invention, through slots 18 are formed at the upper ends of the L-shaped baffles 4, sliding grooves 17 are formed in the inner walls on both sides of the through slots 18, an electromagnet 22 is arranged on the inner wall at the bottom of the through slots 18, and a permanent magnet 20 is slidably connected to the inner wall of the sliding groove 17.

[0025] As a further solution in the present invention, the magnetic force generated after the electromagnet 22 is energized repels the permanent magnet 20, a connecting spring 21 is fixedly connected between the electromagnet 22 and the permanent magnet 20, a telescopic baffle 19 is fixedly connected to the top of the permanent magnet 20, and the width of the telescopic baffle 19 is the same as the width of the L-shaped baffle 4. By controlling the magnitude of the current input to the electromagnet 22, the magnitude of the magnetic force generated by the electromagnet 22 can be controlled. Since the magnetic force generated after the electromagnet 22 is energized repels the permanent magnet 20, the length of the telescopic baffle 19 extending out of the through slot 18 can be adjusted, so as to adapt to different stacking heights, and one side of the stacked corrugated cardboard can be limited, so that the stacked corrugated cardboard becomes stable during the lifting process and avoids tilting.

[0026] Working principle: Multiple corrugated cardboard sheets are placed on the conveyor belt 1, and there are gaps between adjacent corrugated cardboard sheets. The conveyor belt 1 can move these corrugated cardboard sheets arranged with gaps. When a corrugated cardboard sheet contacts the pressure sensor 16 on the L-shaped baffle 4, at this time, the corrugated cardboard sheet is between two L-shaped lifting plates 13. Since the conveyor belt 1 moves the corrugated cardboard sheet, and the L-shaped baffle 4 can block the movement of the corrugated cardboard sheet, the pressure sensor 16 can generate a pressure signal, and the generated pressure signal can be received by an external controller. When the external controller receives this pressure signal, the driving mechanism is started, and the driving motor 3 can rotate the second transmission wheel 12 at the output shaft end. Since a transmission belt 11 is sleeved between the second transmission wheel 12 and the first transmission wheel 10 on the outer wall of the rotating cylinder 5, the rotating cylinder 5 can be rotated. During this process, the rollers 9 on the L-shaped lifting plate 13 below the corrugated cardboard sheet will contact it, and as the rotating cylinder 5 rotates, multiple rollers 9 on the L-shaped lifting plate 13 will contact the bottom of the corrugated cardboard sheet above it until the multiple rollers 9 on the L-shaped lifting plate 13 are parallel to the horizontal plane, and then the driving mechanism stops running, and the rotating cylinder 5 stops rotating. And because there are gaps between adjacent corrugated cardboard sheets, during the process of lifting the corrugated cardboard sheet, the next corrugated cardboard sheet will not enter below the lifted corrugated cardboard sheet. Only after the corrugated cardboard sheet is lifted and the driving mechanism stops running, will the next corrugated cardboard sheet gradually enter the gap between the L-shaped lifting plate 13 below the lifted corrugated cardboard sheet and the L-shaped lifting plate 13 adjacent to the L-shaped lifting plate 13 below the next corrugated cardboard sheet. By repeating the above operations, the corrugated cardboard sheets can be continuously and uninterruptedly conveyed while being stacked and placed synchronously, improving the stacking efficiency. After the stacking is completed, the stacked corrugated cardboard sheets are transferred away by an external gripping robot.

[0027] Example 2: Refer to Figures 6-8 , an automated conveying device for producing V-shaped deep-ridged high-strength corrugated cardboard. Compared with Example 1, on the basis of Example 1, hydraulic rods 23 are provided on the outer walls of the tops of the two grooves, and the telescopic ends of the hydraulic rods 23 are fixedly connected with mounting plates 24. Two rotating columns 28 are symmetrically and rotatably connected to the lower ends of the mounting plates 24, and swing plates 25 are fixedly connected to one ends of the two rotating columns 28. During the process of lifting the corrugated cardboard from top to bottom and then stacking it, the hydraulic rods 23 are activated, so that the two swing plates 25 on the mounting plates 24 approach the corrugated cardboard that is lifted and then stacked, so that when stacking, both ends of the corrugated cardboard can be pressed simultaneously, and the stacked corrugated cardboard can be made flat, avoiding deformation of the corrugated cardboard due to uneven force during stacking.

[0028] As a further scheme in the present invention, gears one 27 are fixedly connected to the outer walls of the two rotating columns 28, and the two gears one 27 are meshed. A servo motor one 26 is provided at the other end of one of the rotating columns 28. When the height of the stacked corrugated cardboard gradually becomes higher, the servo motor one 26 drives the rotating column 28 connected thereto to rotate. Since the gears one 27 on the outer walls of the two rotating columns 28 are meshed, the other rotating column 28 will also rotate. Through the above operations, the included angle between the two swing plates 25 becomes smaller or larger, so that both ends of the corrugated cardboard at different heights can be pressed simultaneously, facilitating the flattening work.

[0029] Working principle: During the process of lifting the corrugated cardboard from top to bottom and then stacking it, the hydraulic rods 23 are activated, so that the two swing plates 25 on the mounting plates 24 approach the corrugated cardboard that is lifted and then stacked, so that when stacking, both ends of the corrugated cardboard can be pressed simultaneously, and the stacked corrugated cardboard can be made flat, avoiding deformation of the corrugated cardboard due to uneven force during stacking; when the height of the stacked corrugated cardboard gradually becomes higher, the servo motor one 26 drives the rotating column 28 connected thereto to rotate. Since the gears one 27 on the outer walls of the two rotating columns 28 are meshed, the other rotating column 28 will also rotate. Through the above operations, the included angle between the two swing plates 25 becomes smaller or larger, so that both ends of the corrugated cardboard at different heights can be pressed simultaneously, facilitating the flattening work.

[0030] Example 3: Refer to Figures 9-12 , an automated conveying device for producing V-shaped deep-ridged high-strength corrugated cardboard. Compared with Example 2, on the basis of Example 2, fixing plates three 32 are provided on the other sides of the two grooves, and driving shafts 35 are rotatably connected to the outer walls of the fixing plates three 32. Servo motors two 30 are provided on one sides of the fixing plates three 32, and gears two 31 are fixedly connected to the output shaft ends of the servo motors two 30. Gears three 34 are fixedly connected to the tops of the two driving shafts 35, and the gears three 34 are meshed with the corresponding gears two 31.

[0031] As a further solution in the present invention, fixing sleeves 36 are fixedly connected to the outer walls of the bottoms of the third fixing plates 32, and the central axis of the fixing sleeve 36 coincides with the central axis of the driving shaft 35. The bottoms of the two driving shafts 35 are respectively fixedly connected with a deviation rectifying column one 29 and a deviation rectifying column two 33 with the same diameter. The outer diameter of the fixing sleeve 36 is the same as the diameters of the deviation rectifying column one 29 and the deviation rectifying column two 33, and a plurality of infrared sensors 37 are equidistantly arranged on the outer wall of the fixing sleeve 36. When the conveyor belt 1 conveys corrugated cardboard, some corrugated cardboard may deviate. The deviated corrugated cardboard will first come into contact with the surface of the deviation rectifying column one 29 or the deviation rectifying column two 33. If the deviated corrugated cardboard first comes into contact with the surface of the deviation rectifying column one 29, the infrared sensor 37 above the deviation rectifying column one 29 will detect it. Then, through an external controller, the first servo motor 26 close to the deviation rectifying column one 29 is started. The first servo motor 26 is in meshing engagement with the third gear 34 through the second gear 31, so that the deviation rectifying column one 29 below the driving shaft 35 rotates counterclockwise. Due to the frictional force between the deviation rectifying column one 29 and the corrugated cardboard, when the deviation rectifying column one 29 rotates counterclockwise, it can apply a force to the corrugated cardboard to straighten the corrugated cardboard and prevent it from deviating; if the deviated corrugated cardboard first comes into contact with the surface of the deviation rectifying column two 33, the infrared sensor 37 above the deviation rectifying column two 33 will detect it. Then, through an external controller, the first servo motor 26 close to the deviation rectifying column two 33 is started. The first servo motor 26 is in meshing engagement with the third gear 34 through the second gear 31, so that the deviation rectifying column two 33 below the driving shaft 35 rotates clockwise. Due to the frictional force between the deviation rectifying column two 33 and the corrugated cardboard, when the deviation rectifying column two 33 rotates clockwise, it can apply a force to the corrugated cardboard to straighten the corrugated cardboard and prevent it from deviating, facilitating the subsequent stacking work.

[0032] A conveying method for an automated conveying device for producing V-shaped deep corrugated high-strength corrugated cardboard includes the following steps: S1. The conveyor belt 1 moves a plurality of corrugated cardboard arranged at intervals above it, and the deviation rectifying column one 29 and the deviation rectifying column two 33 can correct the deviated corrugated cardboard. S2. After the corrected corrugated cardboard comes into contact with the pressure sensor 16 on the L-shaped baffle 4, the driving mechanism rotates the rotating cylinder 5, and through the lifting mechanism, the corrugated cardboard can be lifted. After lifting, then the next corrugated cardboard is allowed to enter the gap of the lifted corrugated cardboard, and the above operation is cycled. Thus, through the plurality of lifting mechanisms on the outer wall of the rotating cylinder 5, the corrugated cardboard can be continuously stacked from top to bottom. S3. And when stacking the corrugated cardboard, the hydraulic rod 23 makes the two swing plates 25 on the mounting plate 24 approach the outer wall of the corrugated cardboard, and can simultaneously press both ends of the stacked corrugated cardboard to make the stacked corrugated cardboard flat.

[0033] Working principle: When the conveyor belt 1 conveys corrugated cardboard, some corrugated cardboard may deviate. The deviated corrugated cardboard will first come into contact with the surface of the deviation rectifying column 1, 29 or the deviation rectifying column 2, 33. If the deviated corrugated cardboard first contacts the surface of the deviation rectifying column 1, 29, the infrared sensor 37 above the deviation rectifying column 1, 29 will detect it. Then, through an external controller, the servo motor 1, 26 near the deviation rectifying column 1, 29 will be started. The servo motor 1, 26 is meshed and cooperated with the gear 3, 34 through the gear 2, 31, so that the deviation rectifying column 1, 29 below the driving shaft 35 rotates counterclockwise. Because there is friction between the deviation rectifying column 1, 29 and the corrugated cardboard, when the deviation rectifying column 1, 29 rotates counterclockwise, it can apply force to the corrugated cardboard to make the corrugated cardboard straight and no longer deviate. If the deviated corrugated cardboard first contacts the surface of the deviation rectifying column 2, 33, the infrared sensor 37 above the deviation rectifying column 2, 33 will detect it. Then, through an external controller, the servo motor 1, 26 near the deviation rectifying column 2, 33 will be started. The servo motor 1, 26 is meshed and cooperated with the gear 3, 34 through the gear 2, 31, so that the deviation rectifying column 2, 33 below the driving shaft 35 rotates clockwise. Because there is friction between the deviation rectifying column 2, 33 and the corrugated cardboard, when the deviation rectifying column 2, 33 rotates clockwise, it can apply force to the corrugated cardboard to make the corrugated cardboard straight and no longer deviate, which is convenient for the subsequent stacking work.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
