Description

Technical Field

[0001] The present invention relates to the technical field of waste discharging equipment, and particularly to an automatic waste discharging device for self-adhesive labels. Background Art

[0002] With the continuous improvement of industrial automation, various automated production equipment has been widely applied in various industries. Especially in the packaging industry, self-adhesive labels are increasingly used due to their unique convenience and environmental friendliness. However, in the production process of self-adhesive labels, due to production process problems, a certain proportion of defective products will inevitably be generated. How to effectively process these defective products, especially the valuable material parts among them, has become an important issue on the production line. Currently, there are already various solutions to this problem on the market, but most of them still remain in the stage of manual handling or semi-automation, not only with high labor intensity but also low efficiency, making it difficult to meet the requirements of modern industrial production.

[0003] Currently, to address the waste recycling problem in self-adhesive label production, there are mainly two common solutions: one is to manually pick out the recyclable materials through manual screening; the other is to use simple mechanical equipment to assist manual preliminary classification. The former can ensure relatively high recycling quality, but due to complete reliance on manpower, the efficiency is extremely limited and the cost is high; the latter can reduce the workload of people to a certain extent, but due to the single function of the equipment, it cannot achieve efficient automated operation and often requires a large amount of subsequent manual intervention, resulting in an unsatisfactory overall work efficiency. In addition, both of these methods have relatively large safety hazards, are prone to causing injuries to workers, and also increase the pressure on the enterprise's work safety. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an automatic waste discharging device for self-adhesive labels, which solves the problems that the traditional waste discharging of self-adhesive labels has low automation degree and most processes still need to rely on manual labor, which not only greatly reduces the production efficiency but also may increase the error rate due to human factors. Secondly, the existing equipment design is relatively simple, lacking intelligence and flexibility, and cannot well adapt to self-adhesive labels of different specifications and materials.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automated self-adhesive label waste discharge device, comprising a base, the upper surface of the base is fixedly connected with a side plate, the inner wall of the side plate is fixedly connected with a straightening plate, one outer wall of the base is provided with a waste box, the other outer wall of the base is provided with a finished product box, the upper surface of the side plate is fixedly connected with a fixing plate, the upper surface of the fixing plate is provided with a mounting block 1, the upper surface of the base is fixedly connected with a mounting block 2, a motor is provided inside the mounting block 2, the output end of the motor is connected with a rotating column, the outer wall of the rotating column is provided with a track, the lower surface of the straightening plate is provided on the upper surface of the track, the inner wall of the mounting block 2 is provided with a bearing, and the outer wall of the base is provided with a detection component, and the detection component is used to detect waste products.

[0006] Preferably, the detection component comprises a support column, an outer wall of the support column is fixedly connected to an outer wall of the base, and a camera is fixedly connected to an upper surface of the support column.

[0009] Preferably, a spring 1 is disposed on the outer wall of the baffle, a sliding block is disposed on the outer wall of the spring 1, and a lower outer wall of the sliding block is slidably connected to the interior of the fixed block 1.

[0010] Preferably, a cushion is fixedly connected to the outer wall of the sliding block, and a second fixing block is fixedly connected to the outer wall of the sliding block.

[0011] Preferably, a second spring is provided on the outer wall of the second fixed block, and a mounting ring is slidably connected inside the sliding block.

[0012] Preferably, the outer wall of the second spring is arranged on the right outer wall of the mounting ring, and the left outer wall of the mounting ring is fixedly connected with a second connecting column.

[0013] Preferably, a connecting column 1 is fixedly connected to the right outer wall of the mounting ring, and the outer wall of the connecting column 1 is slidably connected to the inside of the fixing block 2.

[0014] Preferably, a trapezoidal block is fixedly connected to the left outer wall of the second connecting column, and the outer wall of the trapezoidal block is slidably connected to the inside of the sliding block.

[0015] Working principle: Place the self-adhesive label on the upper surface of the crawler. When the motor rotates, it drives the rotating column to rotate. The rotation of the rotating column drives the crawler to rotate, and the crawler drives the self-adhesive label to move. Under the action of the straightening plate, the self-adhesive label will be automatically straightened. When the self-adhesive label passes through the fixing plate and mounting block 1, mounting block 1 will dry the self-adhesive label. When the crawler drives the self-adhesive label into the field of view of the camera, the camera will scan the self-adhesive label. When the camera detects a defective self-adhesive label, the camera will activate the air cylinder. When the air cylinder pushes, it drives the sliding plate and the fixed column to slide. The sliding of the fixed column drives the trapezoidal block to slide. The sliding of the trapezoidal block drives the sliding block to slide inside the first fixed block. At the same time, the sliding block compresses the first spring. When the trapezoidal block touches the limit plate, the trapezoidal block compresses the inside of the sliding block. The trapezoidal block drives the mounting ring to compress the second spring. At the same time, the first connecting column slides inside the second fixed block. Finally, the first spring drives the sliding block and the soft pad to pop the defective self-adhesive label into the waste bin, and the qualified products will enter the finished product bin along the crawler, thus achieving a significant improvement in the automation degree of self-adhesive label waste discharge, reducing the proportion of manual participation, and significantly enhancing the production efficiency and recycling quality; By adding a fixing plate and a first mounting block on the upper surface of the side plate, it can be achieved that when working in cold seasons or low-temperature environments, the surface of the material can be preheated in advance through the preheating module, making the label easier to peel off; while in high-temperature seasons or environments, the temperature can be reduced with the help of the cooling module to prevent the material from being too soft and affecting the separation accuracy.

[0016] When the camera detects a defective self-adhesive label, the camera will activate the air cylinder. When the air cylinder pushes, it drives the sliding plate and the fixed column to slide. The sliding of the fixed column drives the trapezoidal block to slide. The sliding of the trapezoidal block drives the sliding block to slide inside the first fixed block. At the same time, the sliding block compresses the first spring. When the trapezoidal block touches the limit plate, the trapezoidal block compresses the inside of the sliding block. The trapezoidal block drives the mounting ring to compress the second spring. At the same time, the first connecting column slides inside the second fixed block. Finally, the first spring drives the sliding block and the soft pad to pop the defective self-adhesive label into the waste bin, and the qualified products will enter the finished product bin along the crawler, thus achieving the ability to accurately distinguish qualified labels from waste materials and avoiding misjudgment phenomena in traditional methods; Put the self-adhesive label on the upper surface of the track. The rotation of the motor will drive the rotating column to rotate. The rotation of the rotating column will drive the track to rotate. The track will drive the self-adhesive label to move. Under the action of the straightening plate, the self-adhesive label will automatically straighten. When the self-adhesive label passes through the fixed plate and the mounting block, the mounting block will dry the self-adhesive label. When the track drives the self-adhesive label to move into the field of view of the camera, the camera will scan the self-adhesive label. When the camera finds a bad self-adhesive label, the camera will start the pneumatic cylinder. When the pneumatic cylinder is pushed, it will drive the sliding plate and the fixed column to slide. The sliding of the fixed column will drive the trapezoidal block to slide. The sliding of the trapezoidal block will drive the sliding block to slide inside the fixed block one, and the sliding block will squeeze the spring one. When the trapezoidal block touches the limit plate, the trapezoidal block will compress the inside of the sliding block, and the trapezoidal block will drive the mounting ring to compress the spring two. At the same time, the connecting column one will slide inside the fixed block two, and finally the sliding block and the soft pad will be driven by the spring one to bounce the bad self-adhesive label into the waste box, and the qualified products will enter the finished product box along the crawler, so that the equipment can achieve a compact structure, easy maintenance, long service life, good scalability and compatibility, and can easily adapt to different production line environments. The present invention provides an automatic self-adhesive label waste discharge device, which has the following beneficial effects: 1. The present invention places the self-adhesive label on the upper surface of the crawler, and the rotation of the motor will drive the crawler to rotate, thereby greatly improving the degree of automation of the self-adhesive label waste discharge, making the entire waste discharge process highly automated, greatly reducing direct human participation, allowing human resources to be more reasonably allocated to other key links, and the production efficiency has also been improved several times. At the same time, the recycling quality is also significantly improved due to the accuracy and stability of the automated operation, ensuring that waste and qualified products can be accurately distinguished and collected, reducing misclassification and resource waste caused by human factors.

[0017] 2. The present invention detects the self-adhesive labels by using a camera, and automatically distinguishes the self-adhesive labels after detection. Compared with the traditional manual visual inspection or simple mechanical screening method, this detection method based on image recognition technology has extremely high accuracy and reliability, and effectively avoids the misjudgment phenomenon caused by factors such as human fatigue and experience differences in traditional methods. In large-scale production, accurately distinguishing qualified labels from waste is very important to ensure product quality and reduce production costs. This function of the device provides a strong quality guarantee for enterprises.

[0018] 3. The overall architecture of the device of the present invention is designed with a compact and reasonable structure. All components cooperate closely and are scientifically arranged, achieving efficient function integration within a limited space. This compact structure not only makes the device occupy less space in the production workshop, facilitating installation and layout, but also reduces the maintenance difficulty of the device. During long-term use, maintenance personnel can easily inspect, repair, and replace each component, significantly shortening the downtime of the device and improving the continuity of production.

[0019] 4. By adding a fixing plate and mounting block 1 on the upper surface of the side plate in the present invention, when working in cold seasons or low-temperature environments, the surface of the material can be preheated in advance through the preheating module, making the label easier to peel off; while in high-temperature seasons or environments, the temperature can be reduced with the help of the cooling module to prevent the material from being too soft and affecting the separation accuracy. At the same time, the cooling module can effectively reduce the surface temperature of the material, keeping it in a suitable physical state, preventing problems such as label adhesion and deformation due to the material being too soft, and ensuring that the waste discharging work can be carried out efficiently and accurately under various temperature conditions, further improving the applicability and reliability of the device.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Please refer to the attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides an automated self-adhesive label waste discharge device, comprising a base 1, a side plate 2 is fixedly connected to the upper surface of the base 1, a straightening plate 3 is fixedly connected to the inner wall of the side plate 2, a waste box 4 is arranged on the outer wall of one side of the base 1, a finished product box 5 is arranged on the outer wall of the other side of the base 1, a fixing plate 6 is fixedly connected to the upper surface of the side plate 2, a mounting block 1 7 is arranged on the upper surface of the fixing plate 6, a mounting block 2 11 is fixedly connected to the upper surface of the base 1, a motor 8 is arranged inside the mounting block 2 11, a rotating column 9 is connected to the output end of the motor 8, a crawler 10 is arranged on the outer wall of the rotating column 9, the lower surface of the straightening plate 3 is arranged on the upper surface of the crawler 10, a bearing 12 is arranged on the inner wall of the mounting block 2 11, and a detection component is arranged on the outer wall of the base 1, and the detection component is used to detect waste products; the detection component comprises a support column 13, the outer wall of the support column 13 is fixedly connected to the outer wall of the base 1, and the upper surface of the support column 13 is fixedly connected to a camera 14.

[0024] Specifically, the motor 8, the rotating column 9 and the crawler 10 are responsible for delivering the self-adhesive labels to be processed into the detection area. The straightening plate 3 is used to straighten the self-adhesive labels during transportation. The image information is captured by sensors such as the camera 14, and based on the preset algorithm, it is determined which labels are qualified products and which need to be discharged as waste. The motor 8 uses a stepper motor to ensure positioning accuracy. The camera 14 uses a high-definition CCD camera to ensure the quality of image acquisition, thereby greatly improving the degree of automation of self-adhesive label discharge, making the entire discharge process highly automated and greatly reducing direct manual participation. Human resources can be more reasonably allocated to other key links, and production efficiency has been improved several times. At the same time, the recycling quality has been significantly improved due to the accuracy and stability of automated operations, ensuring that waste materials and qualified products can be accurately distinguished and collected, reducing misclassification and resource waste caused by human factors. The support column 13 is internally a control system core processor, which uses an ARM architecture microcontroller and supports multi-task concurrent execution. It is used to feed back the images captured by the camera 14 to the pneumatic cylinder 16 in a timely manner. The fixing plate 6 and the mounting block 7 are preheating modules and cooling modules for Improve the physical properties of materials under certain specific conditions, so as to further optimize the separation effect. When working in cold seasons or low temperature environments, the preheating module can be used to preheat the surface of the material to make the label easier to peel off; in high temperature seasons or environments, the cooling module can be used to reduce the temperature to prevent the material from being too soft and affecting the separation accuracy. At the same time, the cooling module can effectively reduce the surface temperature of the material to keep it in a suitable physical state, prevent the label from sticking and deforming due to the material being too soft, and ensure that the waste discharge work can be carried out efficiently and accurately under various temperature conditions, further improving the applicability and reliability of the equipment. The waste box 4 and the finished product box 5 are respectively arranged on the outer walls of both sides of the base 1, and the position design is convenient for the classification and collection of labels. The waste box 4 adopts a large-capacity design and a smooth internal structure, which is convenient for the waste to slide and accumulate smoothly. At the same time, it is equipped with a lid that is easy to open and clean, which is convenient for regular cleaning of waste and keeps the working area clean. The finished product box 5 focuses on the protection of qualified labels. A buffer layer is provided inside to prevent the labels from being scratched or squeezed during the collection process, ensuring that the quality of the finished product labels is not affected. The surface of the crawler 10 is made of a special anti-slip and wear-resistant material with good friction, which can reliably drive the self-adhesive label to move.

[0025] Please refer to the attached Figure 4 -Attached Figure 6, a connecting plate 15 is fixedly connected inside the side plate 2. An air cylinder 16 is fixedly connected to the upper surface of the connecting plate 15. The output end of the air cylinder 16 is fixedly connected to a sliding plate 17. A fixing column 18 is fixedly connected to the outer wall of the sliding plate 17. A first fixing block 19 is fixedly connected to the outer wall of the side plate 2. A limiting plate 20 is fixedly connected to the upper surface of the first fixing block 19. A baffle 21 is fixedly connected to the upper surface of the first fixing block 19. A first spring 22 is arranged on the outer wall of the baffle 21. A sliding block 23 is arranged on the outer wall of the first spring 22. The lower outer wall of the sliding block 23 is slidably connected inside the first fixing block 19.

[0026] Specifically, the air cylinder 16 selects a linear motion cylinder driven by a high-performance solenoid valve to achieve fast and stable pushing and pulling actions. When receiving the action instruction sent by the control system, the solenoid valve quickly switches the air circuit, so that the piston in the cylinder extends or retracts at a predetermined speed and stroke under the push of high-pressure gas. Once the camera 14 determines that a certain label is a waste material, the control system immediately sends an instruction to the corresponding cylinder, causing it to start and accurately push the waste material to one side. At the same time, the qualified labels continue to move forward along the set path until the final destination. During the whole process, all actions are carried out continuously and orderly, ensuring the coherence and efficiency of production. The air cylinder 16 is used to push the sliding plate 17 and the fixing column 18 to slide. The sliding of the sliding plate 17 and the fixing column 18 will drive the trapezoidal block 30 to touch the limiting plate 20. The baffle 21 is used to fix and support the first spring 22. The first spring 22 is used to drive the sliding block 23 and the soft pad 24 to push the waste material, so that the waste material falls into the inside of the waste box 4, and the complete material will fall into the inside of the finished product box 5 along the crawler 10. By using the camera 14 to detect the self-adhesive labels, the self-adhesive labels are automatically distinguished after detection. Compared with the traditional manual visual inspection or simple mechanical screening method, this detection method based on image recognition technology has extremely high accuracy and reliability, effectively avoiding the misjudgment phenomenon caused by factors such as human fatigue and experience differences in the traditional method. In large-scale production, accurately distinguishing qualified labels from waste materials is crucial for ensuring product quality and reducing production costs. This function of this device provides strong quality assurance for enterprises.

[0027] Please refer to the appendix Figure 7 - appendix Figure 8, a soft pad 24 is fixedly connected to the outer wall of the sliding block 23, and a second fixing block 25 is fixedly connected to the outer wall of the sliding block 23; a second spring 26 is arranged on the outer wall of the second fixing block 25, and an installation ring 27 is slidably connected inside the sliding block 23; the outer wall of the second spring 26 is arranged on the right outer wall of the installation ring 27, and a second connecting column 29 is fixedly connected to the left outer wall of the installation ring 27; a first connecting column 28 is fixedly connected to the right outer wall of the installation ring 27, and the outer wall of the first connecting column 28 is slidably connected inside the second fixing block 25; a trapezoidal block 30 is fixedly connected to the left outer wall of the second connecting column 29, and the outer wall of the trapezoidal block 30 is slidably connected inside the sliding block 23.

[0028] Specifically, when the trapezoidal block 30 contacts the outer wall of the limiting plate 20, the trapezoidal block 30 will drive the second connecting column 29 and the installation ring 27 to compress the second spring 26 and store elastic potential energy. The first connecting column 28 slides in the slideway inside the second fixing block 25, guiding and limiting the movement of the installation ring 27, preventing the installation ring 27 from shifting or shaking during the movement, ensuring the uniform force and stable movement of the entire mechanical structure. When the trapezoidal block 30 leaves the limiting plate 20, the second spring 26 will drive the trapezoidal block 30 and the second connecting column 29 to reset. The second spring 26 is used to support the second spring 26, and the first connecting column 28 is used to enhance the service life of the second spring 26 and prevent the second spring 26 from loosening or shifting during use. The soft pad 24 is used to eject the waste. The overall structure of the device is compact and reasonable in design. Each component is closely matched and scientifically arranged, achieving efficient function integration in a limited space. This compact structure not only makes the device occupy less space in the production workshop, facilitating installation and layout, but also reduces the maintenance difficulty of the device. During long-term use, maintenance personnel can easily inspect, repair, and replace each component, significantly shortening the downtime of the device and improving the continuity of production. The soft pad 24 fixedly connected to the outer wall of the sliding block 23 is made of a rubber material with high elasticity and a moderate friction coefficient. This material property enables the soft pad 24 to generate sufficient friction when contacting the self-adhesive label, ensuring an effective pushing force on the waste label, and at the same time avoiding damage to the label surface. With its soft texture and friction with the label, the soft pad 24 precisely pushes the waste label into the waste bin 4 to complete the separation operation of the waste.
