Description

Technical Field

[0001] This invention belongs to the field of corrugated cardboard conveying technology, and in particular relates to an automatic corrugated cardboard conveying and stacking device. Background Technology

[0002] Corrugated cardboard, as a widely used packaging material, relies heavily on automated production and subsequent conveying and stacking processes to improve packaging efficiency. Traditional corrugated cardboard conveying and stacking methods largely depend on manual handling or simple mechanical devices, which present numerous technical bottlenecks in practice.

[0003] (1) When the existing corrugated cardboard conveying and stacking devices are working, they mostly transport corrugated cardboard to the manual stacking station by conveyor belt, and then the operators carry out the stacking operation of the corrugated cardboard. There is no automated conveying mechanism between the conveyor belt and the stacking station.

[0004] (2) Existing corrugated cardboard conveying and stacking devices are usually not highly integrated, and the linkage between different drive components is not smooth enough, resulting in a lag in the mechanical response of the entire conveying process, which cannot effectively meet the production needs of efficient positioning and conveying of corrugated cardboard. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic conveying and stacking equipment for corrugated cardboard, which solves the problems in the background art through the specific structural design of the belt conveyor system, guide roller conveyor assembly, lifting and reversing assembly and negative pressure adsorption assembly.

[0013] The invention is further configured such that the negative pressure adsorption assembly includes an L-shaped carrier, a guide wheel is rotatably mounted on the bottom of the L-shaped carrier and is used to roll along each channel, and a negative pressure generator is mounted on the top of the L-shaped carrier above the belt transmission system; a suction cup is provided below the L-shaped carrier, and the suction cup is connected to the negative pressure generator through a negative pressure pipe; a photoelectric sensor is installed at the top inside the L-shaped carrier; the negative pressure suction part is composed of a negative pressure generator, a suction cup and a negative pressure pipe; the output shaft of the horizontal drive part is connected to a linkage plate, and a sliding member fixed to the L-shaped carrier is slidably provided on the linkage plate.

[0014] The invention is further configured such that two movable rods are horizontally slidably arranged on the mounting frame, a positioning plate is fixed at the end of the movable rod and close to the top of the guide roller, a movable plate is provided between the positioning plate and the mounting frame and fixed to the movable rod, an elastic element is provided between the movable plate and the mounting frame, and an inclined force plate is fixed at the bottom of the movable plate.

[0017] 2. This invention utilizes the lifting drive unit of the lifting and reversing assembly to control the up and down movement of the lifting seat. Through the meshing transmission of the vertical toothed plate, transmission gear and bidirectional screw, the lifting motion is cleverly transformed into the lateral opening or closing motion of the two moving plates. This linkage design of multi-directional motion driven by a single power source simplifies the equipment structure and improves the mechanical response speed and overall integration when connecting multiple processes.

[0018] 3. This invention uses a transmission unit or elastic reset mechanism to control the two positioning plates that are set opposite each other to move closer together synchronously. By using the lateral squeezing action of the positioning plates on the corrugated cardboard, the corrugated cardboard that may be misaligned at the top of the guide roller can be automatically corrected and positioned to the center position of the guide roller, ensuring that the horizontal spacing is strictly consistent with the width of the cardboard. Combined with the airflow impact force generated by the airflow pushing part of the hollow guide component, the cardboard can slide smoothly along the guide roller and fall smoothly, ensuring that the corrugated cardboard falling into the stacking guide frame can be neatly aligned and stacked, solving the technical bottleneck of easy misalignment and unstable falling in traditional stacking.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1, please refer to Figures 1 to 4 This invention relates to an automatic conveying and stacking equipment for corrugated cardboard, comprising a belt conveyor system 1; a guiding conveying mechanism is provided at the end of the belt conveyor system 1; the guiding conveying mechanism includes a guide roller conveying assembly 2, a lifting and reversing assembly 6, and a negative pressure adsorption assembly 8; the guide roller conveying assembly 2 includes a guide roller group, positioning parts located on opposite sides of the guide roller group, and a transmission part for adjusting the spacing between the positioning parts; a stacking guide frame 3 is provided at the end of the guide roller group; the guide roller group is located on one side of the belt conveyor system 1; a vertical guide plate 4 is provided on the side of the belt conveyor system 1 opposite to the guide roller group; and a horizontal channel 5 is provided on one side of the vertical guide plate 4.

[0033] The lifting and reversing assembly 6 slides against the vertical guide plate 4 on one side and passes through the belt conveyor system 1 on the other side. The lifting and reversing assembly 6 includes an inclined channel 7 and a reversing channel located on one side of the vertical guide plate 4, and an airflow pushing part located on one side of the guide roller group. The negative pressure adsorption assembly 8 is located above the belt conveyor system 1 and includes a guide wheel 9 and a negative pressure adsorption part. When the inclined channel 7 is connected to the horizontal channel 5, the negative pressure adsorption assembly 8, which moves along the inclined channel 7, adsorbs the corrugated cardboard 10. When the reversing channel is connected to the horizontal channel 5, the negative pressure adsorption assembly 8, which moves along the reversing channel, transports the corrugated cardboard 10 to the guide roller group and pushes it into the stacking guide frame 3 through the airflow pushing part.

[0034] The specific structure of the guide roller conveying assembly 2 in this invention is as follows: Figure 3 As shown, the guide roller conveying assembly 2 also includes a support frame 11. A horizontal drive unit 12 is installed on one side of the support frame 11. The horizontal drive unit 12 can be a cylinder or an electric push rod. The vertical guide plate 4 is fixedly installed on the inner wall of the support frame 11 near the horizontal drive unit 12. The stacking guide frame 3 is located above the support frame 11 at a position away from the horizontal drive unit 12. A stacking station for placing the stacking frame is provided below the stacking guide frame 3. The corrugated cardboard 10 pushed into the stacking guide frame 3 can fall into the stacking frame at the stacking station along the stacking guide frame 3 to achieve vertical stacking.

[0035] Furthermore, two vertical guide rails 13 are symmetrically fixed at the bottom of the support frame 11, close to the vertical guide plate 4. A lifting drive unit 14 is installed on one side of the vertical guide rail 13. The lifting drive unit 14 can be a cylinder or an electric push rod. A support frame 15 is fixed on the side of the support frame 11 away from the horizontal drive unit 12. The stacking guide frame 3 is fixedly installed inside the support frame 15. A vertically arranged limiting guide frame 16 is fixed between the support frame 11 and the stacking guide frame 3. When the stacking frame is placed directly below the stacking guide frame 3 with the limiting guide frame 16 attached, the inner wall of the stacking frame is flush with the inner wall of the stacking guide frame 3, and the top of the stacking frame is close to the bottom of the stacking guide frame 3. In this way, the corrugated cardboard 10 inside the stacking guide frame 3 can fall smoothly into the stacking frame.

[0036] The installation method of the guide roller assembly on the support frame 15 in this invention is as follows: Figure 3 As shown, the guide roller assembly consists of several guide rollers 17. The guide rollers 17 are rotatably mounted inside the support frame 15 and located on the side of the stacking guide frame 3 near the belt conveyor system 1. The support frame 15 is fixedly provided with mounting frames 18 on both sides. Two moving rods 19 are horizontally slidably provided on the mounting frames 18. The ends of the moving rods 19 are fixed with positioning plates 20 close to the top of the guide rollers 17. A moving plate 21 fixed to the moving rods 19 is provided between the positioning plate 20 and the mounting frame 18. The positioning part consists of the moving rods 19, the positioning plate 20 and the moving plate 21. In the initial state, the two positioning plates 20 are closest to each other. At this time, the horizontal distance between the two positioning plates 20 is consistent with the width of the corrugated cardboard 10. When the two positioning plates 20 are close to the side of the corrugated cardboard 10, the corrugated cardboard 10 can be accurately put into the stacking guide frame 3 during the pushing process.

[0037] The specific structure of the lifting and reversing component 6 in this invention is as follows: Figure 4As shown, the lifting and reversing assembly 6 also includes a lifting seat 22. A limit plate 23 and a mounting plate 24 are fixed to the bottom of the lifting seat 22. The limit plate 23 is slidably fitted between the vertical guide rails 13, and the mounting plate 24 is connected to the output shaft of the lifting drive unit 14. A support rod 25 that passes through the belt transmission system 1 is fixed to one side of the lifting seat 22. A vertical toothed plate 26 is fixedly installed at the end of the support rod 25. A transmission gear 27 that meshes with the vertical toothed plate 26 is rotatably installed on the limit guide 16. The vertical toothed plate 26 is always meshed with the transmission gear 27. A bidirectional screw 28 is fixedly installed on the transmission gear 27. A moving plate 21 is sleeved on the bidirectional screw 28 and threadedly fitted. The transmission unit consists of the transmission gear 27, the bidirectional screw 28, and the vertical toothed plate 26.

[0038] Furthermore, both the inclined channel 7 and the reversing channel are located on the lifting seat 22. The reversing channel consists of the horizontal channel 29 and the inclined channel 30 that are interconnected. A hollow guide 31 fixed to the support rod 25 is provided between the guide roller group and the belt transmission system 1. The bottom of the support rod 25 is connected to the air supply 32 located below the guide roller group through the mounting seat. The air supply 32 and the hollow guide 31 are connected through the guide pipe 33. The airflow pushing part consists of the air supply 32, the guide pipe 33 and the hollow guide 31.

[0039] The specific structure of the negative pressure adsorption component 8 in this invention is as follows: Figure 8 and Figure 9 As shown, the negative pressure adsorption assembly 8 also includes an L-shaped carrier 34, with a guide wheel 9 rotatably mounted on the bottom of the L-shaped carrier 34. The guide wheel 9 is used to roll along each channel. A negative pressure generator 35 is mounted on the top of the L-shaped carrier 34, located above the belt transmission system 1. A suction cup 36 is provided below the L-shaped carrier 34. The suction cup 36 is connected to the negative pressure generator 35 through a negative pressure pipe 37. A photoelectric sensor 38 is installed on the top of the L-shaped carrier 34. The negative pressure adsorption part consists of the negative pressure generator 35, the suction cup 36, and the negative pressure pipe 37. The output shaft of the horizontal drive part 12 is connected to a linkage plate. A sliding member fixed to the L-shaped carrier 34 is slidably mounted on the linkage plate.

[0040] Initially, guide roller 9 is located within and supported by horizontal channel 5. At this time, the negative pressure suction unit is above the belt conveyor system 1. The inclined channel 7 on the lifting seat 22 is aligned and connected to the horizontal channel 5. The two opposing positioning plates 20 are closest to each other. The top of the hollow guide component 31 retracts below the guide roller 17. During the operation of the conveyor belt on the belt conveyor system 1, when the control system receives a trigger signal from the photoelectric sensor 38, it controls the belt conveyor system 1 to stop operating. At this time, the corrugated cardboard 10 moves to below the negative pressure suction unit and then is driven by the horizontal drive... The moving part 12 pushes the L-shaped carrier 34 to move towards the guide roller group to the preset position. The guide wheel 9 enters the inclined channel 7 along the horizontal channel 5, so that the L-shaped carrier 34 drives the negative pressure suction part to move horizontally and downward at the same time until the suction cup 36 adheres to the top of the corrugated cardboard 10. After the negative pressure adsorption of the corrugated cardboard 10 is achieved by the suction cup 36, the horizontal driving part 12 pushes the L-shaped carrier 34 to move in the opposite direction to complete the reset. At this time, the guide wheel 9 returns to the horizontal channel 5 along the inclined channel 7, and the corrugated cardboard 10 moves above it as the suction cup 36 disengages from the belt transmission system 1.

[0041] Subsequently, the lifting drive unit 14 controls the entire lifting and reversing assembly 6 to move downwards to a preset position. At this time, the horizontal channel 29 is aligned and connected with the horizontal channel 5. During this process, the descending vertical toothed plate 26 drives the transmission gear 27 to rotate. The bidirectional screw 28, which rotates synchronously with the transmission gear 27, drives the two opposing moving plates 21 to move away from the outside of the guide roller 17. Then, the horizontal drive unit 12 pushes the L-shaped carrier 34 to move towards the guide roller group to the preset position. During this process, the guide roller 9 first moves along the horizontal channel 5 and the water... The horizontal channel 29 moves to the intersection of the horizontal channel 29 and the inclined channel 20. At this time, the corrugated cardboard 10 sucked by the negative pressure moves to the top of the guide roller 17. The guide wheel 9 then enters the preset position in the inclined channel 20 along the horizontal channel 29. The corrugated cardboard 10 falls to the top middle position of the guide roller 17. After the suction cup 36 releases the negative pressure suction on the corrugated cardboard 10, the horizontal drive unit 12 pushes the L-shaped carrier 34 to move in the opposite direction to complete the reset. At this time, the guide wheel 9 rolls along the inclined channel 20 and the horizontal channel 29 into the horizontal channel 5.

[0042] Next, the lifting drive unit 14 controls the entire lifting and reversing assembly 6 to move upwards back to its initial position. At this time, the inclined channel 7 is aligned and connected with the horizontal channel 5 again. During this process, the vertical toothed plate 26, which moves upwards, drives the transmission gear 27 to rotate in the opposite direction. The bidirectional screw 28, which rotates synchronously with the transmission gear 27, drives the two opposing moving plates 21 to move closer together to complete the reset. During the reset process of the moving plate 21 and the positioning plate 20, the positioning plate 20 exerts a lateral squeezing effect on the corrugated cardboard 10, so that the corrugated cardboard 10, which may be misaligned at the top of the guide roller 17, is positioned at the center of the guide roller 17. At this time, the top of the hollow guide member 31 is raised again above the guide roller 17. Figure 1 and Figure 2 At the indicated position, the air supply device 32 and the guide pipe 33 are then activated to continuously deliver airflow into the inner cavity of the hollow guide member 31. Under the impact of the airflow, the corrugated cardboard 10 slides along the guide roller 17 and falls into the stacking guide frame 3. The corrugated cardboard 10 in the stacking guide frame 3 falls smoothly into the stacking frame to achieve stacking. After the stacking of the corrugated cardboard 10 is completed, the air supply device 32 is stopped. When the next corrugated cardboard 10 on the belt conveyor system 1 moves to the bottom of the negative pressure suction section, the corrugated cardboard 10 can be conveyed and stacked into the stacking frame again in the same way as above.

[0043] Example 2, please refer to Figures 5 to 9 Two sliding rods 19 are horizontally mounted on the mounting frame 18. A positioning plate 20 close to the top of the guide roller 17 is fixed at the end of the sliding rod 19. A sliding plate 21 fixed to the sliding rod 19 is provided between the positioning plate 20 and the mounting frame 18. An elastic element 39 is provided between the sliding plate 21 and the mounting frame 18. An inclined force plate 40 is fixed at the bottom of the sliding plate 21. The positioning part is composed of the sliding rod 19, the positioning plate 20, the sliding plate 21, the elastic element 39 and the inclined force plate 40.

[0044] The specific structure of the lifting and reversing component 6 in this invention is as follows: Figure 7As shown, the lifting and reversing assembly 6 also includes a lifting seat 22. A support rod 25 that passes through the belt transmission system 1 is fixed on one side of the lifting seat 22. A connecting frame 41 is fixed at the end of the support rod 25. Guide wheels 42 are rotatably mounted on both sides of the connecting frame 41. The guide wheels 42 are attached to the inclined surface of the corresponding inclined force plate 40. In the initial state, the two positioning plates 20 that are set opposite each other are closest to each other. The negative pressure suction part is above the belt transmission system 1. The inclined channel 7 on the lifting seat 22 is aligned and connected with the horizontal channel 5. Each guide wheel 42 presses against the inclined surface of the corresponding inclined force plate 40. In controlling the entire lifting... The reversing component 6 moves downward to the preset position, so that the horizontal channel 29 is aligned and connected with the horizontal channel 5. During this process, the guide wheel 42, which moves downward, squeezes the inclined surface of the inclined force plate 40, so that the two oppositely arranged inclined force plates 40 move away from and compress the elastic member 39. The positioning plate 20, which moves synchronously with the inclined force plate 40, moves synchronously to the outside of the guide roller 17. Then, the corrugated cardboard 10 sucked by the negative pressure is moved and transported to the top middle position of the guide roller 17. After the suction cup 36 releases the negative pressure suction on the corrugated cardboard 10, the horizontal drive unit 12 pushes the L-shaped carrier 34 to move in the opposite direction to complete the reset.

[0045] Next, the entire lifting and reversing assembly 6 is controlled to move upwards back to its initial position. During this process, under the elastic restoring force of the elastic element 39, the two opposing positioning plates 20 gradually move closer together. The positioning plates 20 exert a lateral squeezing effect on the corrugated cardboard 10, causing the corrugated cardboard 10, which might have been misaligned at the top of the guide roller 17, to be positioned at the center of the guide roller 17. At this time, the top of the hollow guide element 31 is raised again above the guide roller 17, i.e. Figure 5 At the indicated position, the air supply device 32 and the guide pipe 33 are then activated to continuously deliver airflow into the inner cavity of the hollow guide member 31. Under the impact of the airflow, the corrugated cardboard 10 slides along the guide roller 17 and falls into the stacking guide frame 3. The corrugated cardboard 10 in the stacking guide frame 3 falls smoothly into the stacking frame to achieve stacking. After the stacking of the corrugated cardboard 10 is completed, the air supply device 32 is stopped. When the next corrugated cardboard 10 on the belt conveyor system 1 moves to the bottom of the negative pressure suction section, the corrugated cardboard 10 can be conveyed and stacked into the stacking frame again in the same way as above.
