Description

Technical Field

[0001] This invention relates to the field of corrugated paper technology, specifically to a corrugated paper conveying device based on visual screening. Background Technology

[0002] To transport the slit cardboard to the next process, such as stacking, packaging, or further processing, corrugated cardboard needs to be conveyed after slitting. During this conveying process, visual inspection and rejection of defective cardboard are required. Due to the limitations of cardboard length and conveyor speed, suction cups are often used for separation during rejection. However, over time, dust, debris, and other loose impurities accumulate on the bottom of the suction cups. Current equipment lacks a corresponding cleaning mechanism, and this dust and debris can easily cause equipment malfunctions, such as unstable suction cups and uneven adsorption. The reduced contact area between the suction cup surface and the cardboard leads to decreased suction power and affects the adsorption effect. Insufficient suction power makes it impossible to effectively remove defective cardboard from the conveyor belt, thus impacting overall production efficiency and quality control. Summary of the Invention

A servo motor for driving the rotating shaft is fixedly connected to the outside of the equipment frame. The transmission chain is meshed with the outside of the upper and lower sprockets, and both ends of the transmission chain are fixedly connected to the outside of the conveyor.

[0013] Preferably, the system also includes a palletizing assembly, which includes a support frame vertically slidably mounted at the end of the equipment frame. A vertical slide rod is vertically fixed to the end of the equipment frame. The support frame is vertically slidably connected to the outside of the vertical slide rod. A guide groove is provided on the outside of one end of the conveyor. A guide rod is slidably connected inside the guide groove and fixed to the support frame. Vertical slide grooves are provided on the sides of the support frame. Lifting sliders are slidably connected in the two vertical slide grooves.

[0014] Preferably, the support frame has multiple conveyor rollers 1 rotatably connected inside, the top of the conveyor rollers 1 being at the same height as the end of the conveyor 2. The support frame has conveyor rollers 2 rotatably connected inside and at the top of the conveyor rollers 1. The support frame has two conveyor rollers 3 rotatably connected up and down at one end inside, and the conveyor rollers 3 and 1 are connected by chain drive to each other and to each other between two adjacent conveyor rollers 1.

When defects or dimensional deviations in the cardboard are detected, the material-receiving suction cups downwards to absorb the cardboard and then quickly lift it upwards. The entire screening action is rapid and timely, effectively preventing defective products from being mixed with qualified products. A cleaning brush is set on one side of conveyor two. After the material-receiving suction cups lift the material, conveyor two moves to the area below the material-receiving suction cups to receive the material. During the resetting process, the cleaning brushes clean the material-receiving suction cups, effectively removing dust, debris, and other loose impurities, ensuring vacuum. The suction cups have a high adsorption effect and long service life, reducing the occurrence of screening and conveying operations affected by weak suction cup adsorption. In the palletizing assembly, the support frame is always horizontal under the guidance of the vertical slide bar. With the angle adjustment of one end of the conveyor, the cardboard can be palletized from bottom to top. The two reciprocating screws in the middle of the drive rod drive the positioning push plate to move back and forth towards the center, pushing the palletized cardboard towards the center, keeping the two ends of the material palletized neat. An infrared counter counts the palletized cardboard, making it easy to determine the number of pallets. The entire palletizing process is standardized and orderly, improving palletizing quality and efficiency. Attached Figure Description

Detailed Implementation

[0030] 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.

[0031] Please see Figures 1-11This invention provides a technical solution: a corrugated paper conveying device based on visual screening, comprising: an equipment frame 1 with openings on both sides, a lifting seat 4 at one end of the equipment frame 1; a conveyor 2 placed inside the equipment frame 1, the conveyor 2 being a belt conveyor, with one end of the conveyor 2 rotatably mounted inside the lifting seat 4, and the other end of the conveyor 2 being lifted at the end of the equipment frame 1; an industrial camera 9 for detecting corrugated paper defects and controlling the elevation angle adjustment of the conveyor 2 is installed on the top of the conveyor 2; a material-collecting suction cup 10 for separating corrugated paper and a second conveyor 12 are installed on the top of the conveyor 2; a cleaning brush 14 for cleaning the material-collecting suction cup 10 is installed on one side of the second conveyor 12; when the material-collecting suction cup 10 lifts the material, the second conveyor 12 moves to below the material-collecting suction cup 10 to collect the material; when the second conveyor 12 resets, the cleaning brush 14 cleans the material-collecting suction cup 10.

[0032] It should be noted that this embodiment is equipped with a PLC controller and a corresponding operation panel. The servo motor used in this application is equipped with an encoder. After the height of the lifting seat 4 is adjusted and fixed, its height is below the discharge port of the slitting equipment. After the corrugated paper is slit, it is discharged from the discharge port and falls onto one end of the conveyor 2. The conveyor 2 transports it to one end. During the transport process, the industrial camera 9 is responsible for image acquisition, converting the image of the physical world into a digital signal, which is provided to the PLC controller for processing and decision-making. The PLC controller receives data from the industrial camera (image processing results or sensor signals) and executes control operations according to the preset logic program. When the cardboard has defects or dimensional deviations, the controller will adjust the conveying... The speed-controlled suction cup 10 quickly lifts the cardboard upwards after adsorbing it downwards. Then, the second conveyor 12 moves horizontally below the suction cup 10. Under the action of the limit switch, the vacuum pump cuts off the air supply to the suction cup 10, and the cardboard falls onto the second conveyor 12. Under the action of the timer, the second conveyor 12 slides and resets. During the reset process, the cleaning brush 14 rises upwards. A vacuum cleaner is also installed at one end of the second conveyor 12. The top of the cleaning brush 14 has a through hole for connecting to the vacuum cleaner. The cleaning brush 14 contacts the bottom of the suction cup 10, cleaning it while performing negative pressure vacuum cleaning on the suction cup 10 to remove dust, debris, and other loose debris, thus ensuring the adsorption effect and service life of the vacuum suction cup.

[0033] In one embodiment, a linear guide rail 3 is vertically fixed to the end of the equipment frame 1, and a lifting seat 4 is vertically slidably connected to the outside of the linear guide rail 3. A winch 5 is fixedly connected to the top of the equipment frame 1, and the wire rope of the winch 5 is connected to the top of the lifting seat 4.

[0034] It should be noted that, in this embodiment, when adjusting one end of the conveyor 2, the winch 5 adjusts the height of the lifting seat 4 via the rear wire rope. The lifting seat 4 moves vertically up and down outside the linear guide rail 3, thereby adjusting the height of one end of the conveyor 2 so that it can be used with equipment of different heights.

[0035] In one embodiment, a guide plate 7 is fixedly connected to the top of the conveyor 2, a pressure roller 6 is rotatably connected to one side of the guide plate 7, and a pressure roller 23 is rotatably connected to the side of the conveyor 2 away from the pressure roller 6.

[0036] It should be noted that in this embodiment, when the cardboard enters one end of the conveyor 2, under the guidance of the inclined surface and both sides of the guide plate 7, the cardboard passes through the bottom of the guide plate 7 and enters the bottom of the pressure roller 6 for forward conveying. When it is conveyed to the other end of the conveyor 2, under the downward restriction of the pressure roller 23, the cardboard is conveyed forward at different angles of the conveyor 2.

[0037] In one embodiment, a mounting frame 8 is fixedly connected to the top of conveyor 2, an industrial camera 9 is fixedly connected to one side of the mounting frame 8, a material suction cup 10 is vertically slidably connected to the side of the mounting frame 8 away from the industrial camera 9, a cylinder 11 for driving the material suction cup 10 to rise and fall is fixedly connected to one side of the mounting frame 8, a slider is fixedly connected to the bottom of conveyor 2 and slidably connected to both sides of conveyor 2, a cylinder 3 13 for driving the slider to move is fixedly connected to the top of conveyor 2, a cleaning brush 14 is vertically slidably connected to one side of conveyor 2, and a telescopic electromagnet 15 for driving the cleaning brush 14 to rise and fall is fixedly connected to the outside of conveyor 2.

[0038] It should be noted that in this embodiment, multiple industrial cameras 9 are fixedly connected to one side of the mounting frame 8 via a bracket for visual image detection of the cardboard conveyed from the bottom of the pressure roller 6. A metal frame is fixedly connected to one side of the mounting frame 8, and a metal rod is vertically slidably connected to the middle of the metal frame. A metal plate is fixedly connected to the bottom of the metal rod, and a material-picking suction cup 10 is fixedly connected to the outside of the metal plate. A cylinder 11 that drives the metal plate to rise and fall is fixedly connected to the middle of the metal frame. The cylinder 11 drives the material-picking suction cup 10 to rise and fall rapidly, thereby lifting the bottom cardboard. Because there is a gap between the cardboard conveyors, the material picking will not interfere with other cardboard. When it is necessary to lift the defective cardboard, the controller controls the cylinder 11 to drive the material-picking suction cup 10 to suck it down and then lift it up. Under the action of the timer, the controller controls the... Cylinder 3 13 drives conveyor 2 12 to slide along the length of conveyor 1 2, so that conveyor 2 12 is positioned below the material suction cup 10. A limit switch is installed on the side of conveyor 1 2. When the limit switch of material suction cup 10 is activated, the air supply to material suction cup 10 is cut off, and the cardboard falls to the top of conveyor 2 12. At the same time, the telescopic electromagnet 15 of the controller is energized, and the telescopic electromagnet 15 pushes the cleaning brush 14 upward, so that the bristles of the cleaning brush 14 can contact the material suction cup 10. A vacuum cleaner is also installed at one end of conveyor 2 12. The top of the cleaning brush 14 has a through hole for connection with the vacuum cleaner suction, so as to perform simple cleaning of material suction cup 10 by sweeping and adsorption, and prevent loose debris such as debris from sticking to the bottom of material suction cup 10 and affecting its use.

[0039] In one embodiment, a lifting drive unit is also included, which includes a transmission chain 19. Both sides of the equipment frame 1 opposite to the lifting seat 4 are rotatably connected to sprockets. The two sprockets located at the top are connected by a rotating shaft. A servo motor 20 for driving the rotating shaft is fixedly connected to the outside of the equipment frame 1. The transmission chain 19 is meshed with the outside of the upper and lower sprockets. Metal blocks are fixedly connected to both ends of the transmission chain 19. The metal blocks are fixedly connected to the outside of the conveyor 2.

[0040] It should be noted that in this embodiment, the two ends of the transmission chain 19 are rotatably connected to the side of the conveyor 2 via metal blocks. The servo motor 20 drives the upper sprocket to rotate via a rotating shaft. The upper chain drives the lower sprocket to rotate via the transmission chain 19. During this period, the transmission chain 19 drives the conveyor 2 to move up and down. Due to the flexible structure of the transmission chain 19, it can achieve a small deformation when driving the conveyor 2 to rise and fall, thereby avoiding motion interference. One side of the conveyor 2 is driven by the transmission chain 19 to adjust its height, and the other end of the conveyor 2 rotates with the lifting seat 4, thereby flexibly adjusting the elevation angle of the conveyor 2, which facilitates the palletizing operation of materials during conveying. When the industrial camera 9 detects a defective product, the material suction cup 10 removes it, and the controller controls the servo motor 20 not to drive the transmission chain 19 at the corresponding position. At this time, the height of the conveyor 2 will not be adjusted, thereby preventing palletizing chaos caused by different heights.

[0041] In one embodiment, a palletizing assembly is also included. The palletizing assembly includes a support frame 22 vertically slidably mounted on the end of the equipment rack 1. A vertical slide rod 21 is vertically fixed to the end of the equipment rack 1. The support frame 22 is vertically slidably connected to the outside of the vertical slide rod 21. A guide groove 36 is provided on the outside of one end of the conveyor 2. A guide rod 17 is slidably connected inside the guide groove 36 and fixed to the support frame 22. Vertical slide grooves are provided on the sides of the support frame 22. Lifting sliders 25 are slidably connected in the two vertical slide grooves. Lifting pressure rollers 24 are rotatably connected between the two lifting sliders 25. A limiting rod 26 is fixedly connected to the top of the lifting slider 25 and slidably connected to the support frame 22. A spring 27 is sleeved on the outside of the limiting rod 26. Electromagnets 28 are fixedly connected to the bottom of the lifting slider 25 and the outside of the support frame 22. The two electromagnets 28 have the same magnetic poles when energized. The inside of the support frame 22... Multiple conveyor rollers 29 are rotatably connected. The top of the conveyor rollers 29 is at the same height as the end of the conveyor 12. A second conveyor roller 30 is rotatably connected inside the support frame 22 and located on top of the conveyor rollers 29. Two third conveyor rollers 31 are rotatably connected up and down at one end inside the support frame 22. The third conveyor rollers 31 and the first conveyor rollers 29, as well as the two adjacent conveyor rollers 29, are connected by chain drive. A second servo motor 35 that drives one of the conveyor rollers 29 is fixedly connected to one end of the support frame 22. A chute is fixedly connected to the end of the support frame 22. A positioning push plate 32 is slidably connected inside the chute. A drive rod 34 that is rotatably connected to the third conveyor roller 31 is rotatably connected inside the chute. Two reciprocating screws are fixedly connected to the middle of the drive rod 34 to drive the positioning push plates 32 on both sides to move back and forth inward to the middle of the chute to center and align the material. An infrared counter 33 is fixedly connected to the middle of the chute.

[0042] It should be noted that in this embodiment, the support frame 22 remains horizontal under the guidance of the vertical slide bar 21. During the lifting and lowering process at the end of the conveyor 2, the guide rod 17 cooperates with the guide groove 36. The guide groove 36 drives the support frame 22 to rise and fall along the vertical slide bar 21 through the guide rod 17. During this period, the guide rod 17 slides inside the guide groove 36, thereby achieving a height correspondence between the support frame 22 and the end of the conveyor 2. The cardboard passes through the bottom of the pressure roller 23 into the support frame 22. During this period, the controller sends a start signal according to the preset logic, activating the time relay. After receiving the signal from the controller, the time relay uses delay control to precisely adjust the energizing time of the electromagnet, ensuring that the gap is in a suitable state. When the contacts of the time relay close, current flows through the coil of the electromagnet, energizing it and generating a magnetic field. When the two electromagnets 28 are energized, their repulsive force interacts with the spring force of the limit rod 26 and the gravity of the lifting roller 24, causing the lifting slider 25 to move the limit rod 26 and the lifting roller 24 upwards. When the time relay de-energizes the electromagnets 28, the spring 27 drives the lifting slider 25 to move the lifting roller 24 downwards. This cycle repeats, achieving the reciprocating up-and-down movement of the lifting roller 24. This, in turn, presses and guides the end of the cardboard downwards during the angle adjustment of the conveyor belt, allowing it to smoothly enter between the first conveyor roller 29 and the second conveyor roller 30. The servo motor 35 drives the chain to drive the first conveyor roller 29. Conveyor roller 29 drives conveyor roller 31 to rotate via a chain. Under the conveying of conveyor roller 29, the cardboard can enter between conveyor rollers 31. Conveyor roller 31 pushes the cardboard out from one end of the support frame 22. With the adjustment of the end angle of conveyor 2, the cardboard can be stacked from bottom to top. During this period, conveyor roller 31 drives drive rod 34 to rotate via synchronous pulley. The two reciprocating screws in the middle of drive rod 34 drive positioning push plate 32 to move back and forth towards the center in the chute. This can push the stacked cardboard towards the center to keep both ends consistent, thus keeping the two ends of the stacked material neat. During the stacking process, infrared counter 33 counts the stacked cardboard to facilitate the determination of the number of stacks.

[0043] In one embodiment, an L-shaped receiving plate 16 is slidably connected inside the equipment frame 1 and below the support frame 22. A servo electric cylinder 18 that drives the receiving plate 16 to slide is fixedly connected inside the equipment frame 1 for switching the receiving position of the tray.

[0044] It should be noted that in this embodiment, the receiving plate 16 has a material feeding tray on top. When the conveying roller 31 in the middle of the support frame 22 arranges the materials one by one from bottom to top on the top of the material feeding tray, when the number of cardboard stacks reaches the preset value, the controller controls the servo cylinder 18 to drive the receiving plate 16 forward, so that the material feeding tray moves forward. In this way, the materials placed at the bottom can be stacked and arranged again. In this cycle, the tray can be filled in an orderly manner.
