Description

Technical Field

[0001] This invention relates to the field of paperboard production technology, and in particular to a visually integrated suspended conveyor device and method for paperboard production. Background Technology

[0002] In the paperboard production process, conveying devices are key equipment connecting various production steps, and their performance directly affects production efficiency and product quality. Traditional paperboard conveying methods mainly include belt conveyors, roller conveyors, and chain conveyors, which typically transport paperboard horizontally. However, with the increasing demands for product quality in modern manufacturing, especially the stringent requirements for the appearance quality of paperboard, traditional conveying methods have gradually revealed many shortcomings.

[0003] Firstly, traditional horizontal conveying methods easily cause scratches, indentations, and other damage to the cardboard surface during transport. Because the cardboard surface is in direct contact with the conveyor belt or rollers, friction inevitably leaves marks on the surface during long-distance transport, severely affecting the cardboard's appearance. For products with high surface finish requirements, such damage is often unacceptable, leading to product downgrading or even scrapping, resulting in significant economic losses.

[0004] Secondly, traditional conveyor systems lack effective online quality inspection capabilities. During cardboard production, various quality issues may arise, such as damage, stains, printing defects, and dimensional deviations. Traditional conveyor systems can only perform simple transport functions and cannot detect and remove defective products in real time. This leads to defective products flowing into subsequent processes, wasting resources and potentially affecting the overall quality of the final product. Companies typically need to assign dedicated quality inspectors for manual sampling, a method that is inefficient, has a high rate of missed inspections, and is unsuitable for the demands of modern large-scale production.

[0005] Secondly, traditional conveyor systems have low loading efficiency. Currently, common loading methods include manual loading or simple robotic arm gripping. Manual loading is labor-intensive, inefficient, and prone to damaging the cardboard due to improper operation. Ordinary robotic arm gripping methods are less adaptable to handling different cardboard sizes, making it difficult to achieve fast and accurate positioning and gripping. Especially when cardboard needs to be transferred from a horizontal to a vertical position for suspended conveying, traditional loading devices often require complex flipping mechanisms, increasing equipment costs and failure rates.

[0006] Furthermore, the defective product recovery and handling of traditional conveying devices is not intelligent enough. When defective products are detected, manual intervention is usually required for removal and recovery, which not only affects the continuous operation of the production line but also increases labor costs. Moreover, the defective product recovery process lacks an effective buffering and sorting mechanism, which can easily lead to the accumulation and disorder of defective products, hindering subsequent classification, processing, analysis, and improvement. Summary of the Invention

[0007] The purpose of this invention is to provide a vision-integrated overhead conveyor device and method for cardboard production, which aims to solve the problems of easy damage during cardboard conveying, lack of online detection, low feeding efficiency, and unintelligent recycling of defective products in the prior art, and to achieve efficient and damage-free conveying and intelligent quality management of cardboard.

[0008] To achieve the above objectives, the present invention provides a vision-integrated overhead conveyor for cardboard production, comprising a feeding assembly, a conveying assembly, a vision inspection assembly, and a recycling assembly.

The conveying assembly includes a moving chain, a drive wheel, a support wheel, a drive motor, and multiple grippers. The support wheel supports the moving chain, and the drive wheel is driven to rotate by the drive motor to rotate the moving chain. The multiple grippers are arranged on the moving chain to grip the cardboard in a vertical position. The visual inspection component is used to inspect the appearance of cardboard in a vertical position; The recycling component is used to recycle cardboard that fails the appearance inspection.

[0009] The lifting device includes a lifting cylinder, a lifting plate, and a buffer elastic element. The lifting cylinder is fixed to one side of the placement plate, the lifting plate is connected to the output end of the lifting cylinder, and the buffer elastic element is disposed between the lifting cylinder and the lifting plate.

[0010] The suction cup assembly includes multiple suction cups, an air channel, and an air pump. The multiple suction cups are mounted on the rotating rod, the air channel is connected to the multiple suction cups, and the air pump is connected to the air channel.

[0011] The clamp includes a connecting seat, two clamping plates, a clamping cylinder, two push rods, and an alignment detection module. The connecting seat is used to connect with the moving chain. The two clamping plates are rotatably disposed on one side of the connecting seat. The clamping cylinder is disposed on the connecting seat. One end of each of the two push rods is connected to the two clamping plates, and the other end of each push rod is connected to the output end of the clamping cylinder. The alignment detection module is disposed on the connecting seat and is used to detect the position of the cardboard.

[0012] The clamping plate includes a plate body and a flexible pad, wherein the flexible pad is disposed on the inner side of the plate body.

[0013] The alignment detection module includes a photoelectric detection unit, a judgment unit, and a control unit. The photoelectric detection unit is mounted on the connector and is used to continuously emit photoelectric signals. The judgment unit is used to determine whether the cardboard is in place based on the photoelectric signals. The control unit is used to activate the clamping plate to hold the cardboard after it is in place.

[0014] The visual inspection component includes a visual inspection module, a defective product judgment module, and a control module. The visual inspection module is used to acquire an appearance image of the cardboard. The defective product judgment module is used to identify and classify the defects of the cardboard based on the appearance image. The control module is used to control the clamp to release when a cardboard belonging to the defective product moves to the location of the recycling component, so that the recycling component can recycle the defective product.

[0015] The recycling assembly includes a recycling bin, a gas nozzle, and a correction plate. The recycling bin is located below the moving chain, and the gas nozzle is located on one side of the recycling bin for spraying air onto the falling cardboard to move it to a horizontal position.

The flipping process is smooth and reliable, avoiding the complexity and malfunction issues of traditional flipping mechanisms. The conveying component adopts a suspended conveying method. After the cardboard is clamped by the gripper, it is suspended and conveyed vertically. The cardboard surface does not come into contact with any conveying components, effectively avoiding scratches and indentations on the cardboard surface during conveying, ensuring the appearance quality of the cardboard. The vision inspection component performs real-time appearance inspection of the cardboard during conveying, promptly detecting various quality problems such as damage, stains, and printing defects, and automatically identifying and classifying defective products, achieving online quality monitoring. The recycling component automatically receives and sorts defective products. Gas nozzles and a correction plate ensure that defective products fall smoothly into the recycling bin and are neatly stacked for subsequent processing.

Detailed Implementation

[0028] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0029] First embodiment: Please see Figures 1-7 The present invention provides a vision-integrated overhead conveyor for cardboard production, comprising a feeding component, a conveying component, a vision inspection component, and a recycling component.

[0030] The feeding assembly includes a base 101, a placement plate 102, a lifting device 103, a rotating rod 104, a suction cup assembly 105, a rotating gear 106, a support frame 107, and a rack 108. The base 101, serving as the fundamental support structure of the entire feeding assembly, is welded from high-strength steel and possesses sufficient load-bearing capacity and stability. The placement plate 102, mounted on the base 101, is a flat and smooth metal plate used to place the cardboard to be conveyed. The dimensions of the placement plate 102 can be customized according to the cardboard specifications, and its surface can be equipped with positioning marks or limiting borders to facilitate accurate placement of the cardboard by the operator.

[0031] The lifting device 103 is slidably disposed on one side of the placement plate 102, and includes a lifting cylinder 109, a lifting plate 110, and a buffer elastic element 111. The lifting cylinder 109 is fixedly mounted on a bracket on one side of the placement plate 102, and its piston rod is connected to the lifting plate 110. The lifting plate 110 serves as the mounting base for the rotating rod 104, and is provided with a bearing seat to support the rotation of the rotating rod 104. The buffer elastic element 111 is disposed between the lifting cylinder 109 and the lifting plate 110, and is typically a compression spring or a rubber buffer pad, which can effectively absorb the impact force when the cylinder is activated, ensuring the smoothness of the lifting process.

[0032] A rotating rod 104 is rotatably mounted on the lifting plate 110 of the lifter 103 via bearings, with its axis perpendicular to the lifting direction. A suction cup assembly 105 is mounted on the rotating rod 104, comprising multiple suction cups 112, an air duct 113, and an air pump 114. The suction cups 112 are evenly distributed along the length of the rotating rod 104, and each suction cup 112 is connected to the air pump 114 via the air duct 113. When the air pump 114 operates, it generates negative pressure, enabling the suction cups 112 to firmly adhere to the cardboard surface. A rotating gear 106 is fixedly mounted on one end of the rotating rod 104, with its number of teeth and module determined according to design requirements. A support frame 107 is vertically mounted on one side of the placement plate 102, and a rack 108 is fixedly mounted on the support frame 107, with its length parallel to the lifting direction of the lifter 103.

[0033] During operation, the cardboard to be transported is first placed horizontally on the placement plate 102. The air pump 114 is activated to create negative pressure in the suction cup assembly 105, causing the suction cups 112 to adhere to the cardboard surface. Then, the lifting cylinder 109 actuates, pushing the lifting plate 110 upwards, which in turn causes the rotating rod 104 and the suction cup assembly 105 to rise synchronously. When the rotating rod 104 reaches the preset height, the rotating gear 106 engages with the rack 108. Since the rack 108 remains stationary, the rotating gear 106 rolls along the rack 108 during the ascent, causing the rotating rod 104 to rotate. The rotation of the rotating rod 104 causes the suction cup assembly 105 and the adhered cardboard to flip synchronously, changing the cardboard from a horizontal to a vertical position, thus completing the cardboard's orientation change.

[0034] The conveying assembly includes a moving chain 201, a drive wheel 202, a support wheel 203, a drive motor 204, and multiple grippers 205. The moving chain 201 is made of high-strength industrial chain with sufficient load-bearing capacity and wear resistance. The drive wheel 202 and support wheel 203 are respectively located at both ends and the middle of the conveying line to support and guide the movement of the moving chain 201. The drive motor 204 is connected to the drive wheel 202, providing the power required for the chain's movement. Multiple grippers 205 are evenly spaced on the moving chain 201 and move synchronously with the chain to grip vertically positioned cardboard.

[0035] The gripper 205 includes a connecting seat 206, two clamping plates 207, a gripping cylinder 208, two push rods 209, and an alignment detection module 210. The connecting seat 206 is fixedly connected to the moving chain 201 and has mounting holes for mounting the gripping cylinder 208 and other components. The two clamping plates 207 are rotatably mounted on one side of the connecting seat 206 via pins, forming a clamping structure similar to a pliers. The gripping cylinder 208 is fixed to the connecting seat 206, and its piston rod is hinged to one end of the two push rods 209 via a connector. The other ends of the two push rods 209 are respectively hinged to the two clamping plates 207. When the piston rod of the gripping cylinder 208 extends or retracts, the push rods 209 drive the two clamping plates 207 to open and close synchronously, realizing the gripping and release of the cardboard.

[0036] The clamping plate 207 includes a plate body 211 and a flexible pad 212. The plate body 211 is made of metal and has sufficient rigidity and strength. The flexible pad 212 is located on the inner side of the plate body 211 (i.e., the clamping surface) and is made of soft materials such as rubber, silicone, or polyurethane. It can protect the cardboard surface from damage and increase the clamping friction to prevent the cardboard from slipping.

[0037] The alignment detection module 210 includes a photoelectric detection unit 213, a judgment unit 214, and a control unit 215. The photoelectric detection unit 213 is mounted on the connector 206 and typically employs a through-beam or reflective photoelectric sensor capable of continuously emitting and receiving photoelectric signals. When the cardboard enters the clamping area, the photoelectric signal is blocked or reflected, and the judgment unit 214 determines whether the cardboard is in position based on the change in the photoelectric signal. After confirming that the cardboard is in position, the control unit 215 sends an action command to the clamping cylinder 208, driving the clamping plate 207 to close and clamp the cardboard.

[0038] The vision inspection component includes a vision inspection module 301, a defective product judgment module 302, and a control module 303. The vision inspection module 301 is located at the inspection station on the conveyor line and typically includes a high-resolution industrial camera, a light source, and an image acquisition card. The industrial camera can capture images of the cardboard passing through the inspection station in real time, and the light source provides uniform and stable illumination to ensure image quality. The defective product judgment module 302 uses image processing algorithms and machine learning technology to analyze and process the cardboard images, identifying and classifying defects such as scratches, stains, damage, deformation, and printing defects. The control module 303 records the location information of defective products based on the detection results of the defective product judgment module 302. When a defective product moves with the chain to the location of the recycling component, it controls the corresponding gripper 205 to release the cardboard.

[0039] The recycling assembly includes a recycling bin 401, a gas nozzle 402, and a correction plate 403. The recycling bin 401 is located below the moving chain 201 and is used to collect defective cardboard. The gas nozzle 402 is located on one side of the recycling bin 401 and is connected to a compressed air source, capable of spraying high-speed airflow downwards. When the defective cardboard is released from the gripper 205, it falls vertically under gravity, and the airflow from the gas nozzle 402 impacts the side of the cardboard, causing it to flip and become horizontal. The correction plate 403 is located at the entrance of the recycling bin 401 and corrects the landing position of the cardboard, ensuring that it falls accurately into the recycling bin 401.

[0040] The recycling bin 401 includes a body 404, a support plate 405, a screw 406, and a drive motor 407. The body 404 is a rectangular structure with an opening at the top for receiving cardboard. The support plate 405 is horizontally positioned inside the body 404, with its four corners slidingly engaging with guide rails on the inner wall of the body 404, allowing it to move up and down. The screw 406 is vertically positioned inside the body 404, its lower end connected to the output shaft of the drive motor 407, and its upper end threadedly connected to the support plate 405. When the cardboard on the support plate 405 stacks to a preset height, the drive motor 407 starts, driving the screw 406 to rotate, causing the support plate 405 to descend the preset height, making room for subsequent cardboard stacking. This automatic lowering design ensures the continuous operation of the recycling bin 401 and prevents cardboard from being stacked too high, which would affect recycling efficiency. Example

[0041] The present invention also provides a visual integrated overhead conveying method for paperboard production, which employs the above-mentioned visual integrated overhead conveying device for paperboard production, specifically including the following steps: The operator places the cardboard to be transported horizontally on the placement plate 102, ensuring that the cardboard is correctly positioned and its surface is clean. After starting the device, the air pump 114 works to generate negative pressure in the suction cup assembly 105, and the suction cups 112 firmly adhere to the surface of the cardboard.

[0042] The lifting cylinder 109 actuates, pushing the lifting plate 110 upward, which in turn causes the rotating rod 104 and the suction cup assembly 105 to rise synchronously. When the rotating rod 104 rises to a preset height, the rotating gear 106 meshes with the rack 108, and the rotating gear 106 rolls along the rack 108, causing the rotating rod 104 to rotate. The rotation of the rotating rod 104 causes the suction cup assembly 105 and the cardboard it is adsorbed to flip over, changing the cardboard from a horizontal position to a vertical position.

[0043] After the cardboard is flipped to a vertical position, the gripper 205 on the moving chain 201 moves to the cardboard position. Once the photoelectric detection unit 213 of the alignment detection module 210 detects that the cardboard is in place, the judgment unit 214 confirms that the cardboard position is correct, and the control unit 215 controls the clamping cylinder 208 to actuate, driving the clamping plate 207 to close and clamp the cardboard. Subsequently, the air pump 114 stops working, the suction cup 112 releases the cardboard, and the cardboard is held by the gripper 205 and conveyed by the moving chain 201.

[0044] During the conveying process, the cardboard passes through the inspection station of the vision inspection component. The industrial camera of the vision inspection module 301 captures images of the cardboard's appearance. The defective product judgment module 302 analyzes and processes the images to identify whether the cardboard has defects such as scratches, stains, damage, and deformation, and classifies and marks them. The control module 303 records the inspection results and the location information of defective products.

[0045] For products that pass inspection, the gripper 205 continues to hold and transport them to the next process. For cardboard that is found to be defective, when it moves with the chain to the location of the recycling component, the control module 303 controls the corresponding gripper 205 to release the cardboard. The cardboard falls vertically under gravity, and the gas nozzle 402 sprays air to flip the cardboard to a horizontal position. The correction plate 403 corrects the landing position of the cardboard, and the cardboard falls accurately onto the support plate 405 of the recycling bin 401. When the cardboard on the support plate 405 stacks to a preset height, the drive motor 407 drives the screw 406 to rotate, causing the support plate 405 to descend to a preset height to continue receiving subsequent defective cardboard.

[0046] The above steps are repeated continuously to automate the feeding, overhead conveying, visual inspection, and defective product recycling of cardboard. Operators only need to periodically replenish cardboard to the placement board 102 and clean the defective products from the recycling bin 401, which greatly reduces labor intensity and improves production efficiency.

[0047] This invention achieves automatic orientation conversion of cardboard from horizontal to vertical using a feeding component, stable suspended conveying of the cardboard using a conveying component, online inspection of the cardboard's appearance quality using a vision inspection component, and automatic sorting and recycling of defective products using a recycling component. These components work together to form a complete automated production line, significantly improving the automation level of cardboard production and product quality control capabilities.

[0048] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
