Description

Technical Field

[0001] This invention relates to the field of feeder technology for roll material supply, and particularly to a roll material feeder device. Background Technology

[0002] In the field of automated manufacturing, such as electronic component mounting, precision die-cutting, and label printing, roll feeder equipment is widely used. Roll feeder equipment is mainly used to smoothly and continuously transport strip or film rolls (usually including a base film, cover film, and the material being carried) to the processing station at a set speed and trajectory. It is one of the core basic equipment ensuring the efficient operation of automated production lines.

[0003] In actual industrial production, during the continuous operation of feeding equipment, it is often difficult to maintain an ideal transmission state when the material belt is transported from the unloading end to the collecting end. Due to a combination of factors, such as the fit clearance between various transmission components, the cumulative error of the mechanical structure, and the continuous change in the diameter of the material roll itself during unwinding, the tension of the material belt changes along the transmission path. This results in the material belt being easily subjected to uneven stretching or slack during transmission. This fluctuation in transmission state directly disrupts the original force balance of the material belt, leading to abnormal phenomena such as belt deviation, wrinkling, local jamming, or even belt breakage during travel. This forces the equipment to stop frequently for manual intervention and adjustment, affecting production efficiency and product yield. Summary of the Invention

[0004] The main objective of this invention is to provide a coil feeder device that ensures stable tension during material feeding and avoids abnormal feeding.

[0005] To achieve the above objectives, the present invention provides a coil feeder feeding device, comprising: frame; The feeding assembly includes a mounting shaft and a limiting component. The mounting shaft is connected to the frame for mounting the material roll. The limiting component is axially connected to the opposite ends of the mounting shaft and forms a limiting space to restrict the axial displacement of the material roll. The material receiving assembly includes a cover film collecting roller, a bottom film collecting roller, and a drive roller that are spaced apart and connected to the frame. The cover film collecting roller and the bottom film collecting roller are respectively connected to the drive roller via a circular belt drive. The rotation of the drive roller drives the cover film collecting roller and the bottom film collecting roller to rotate synchronously. The material roll is elastically sleeved on the mounting shaft and can rotate relative to the mounting shaft to adjust the tension of the material roll being unloaded.

[0006] In one embodiment, the mounting shaft includes a rotating shaft and a plurality of elastic diaphragms. The rotating shaft is connected to the frame, and each of the elastic diaphragms is spaced apart and connected to the circumference of the rotating shaft. The material roll is clamped onto the elastic diaphragms, and one end of each elastic diaphragm away from the rotating shaft abuts against the inner circumferential wall of the material roll.

[0007] In one embodiment, the limiting component includes a first limiting plate and a second limiting plate. The first limiting plate is connected to the frame, and the second limiting plate is sleeved on the rotating shaft and can move axially relative to the rotating shaft to adjust the distance between the first limiting plate and the second limiting plate.

[0008] In one embodiment, the feeding assembly further includes a fixing member and a plurality of limiting members. Each of the limiting members is connected to the side of the second limiting plate facing away from the first limiting plate and is distributed circumferentially along the rotation axis. A deformation space is formed between two adjacent limiting members. An elastic diaphragm is disposed in the deformation space. The fixing member passes through one of the limiting members and is screwed to it. The fixing member can rotate relative to the limiting member to abut against the rotation axis to fix the second limiting plate.

[0009] In one embodiment, the roll feeder device further includes a correction roller, which is connected to the frame and located vertically between the cover film collecting roller and the bottom film collecting roller. Both ends of the correction roller are provided with third limiting plates, which can be adjusted relative to the axial direction of the correction roller.

[0010] In one embodiment, the roll feeder further includes a stripper and a pick-up table. The stripper is positioned facing the roll and located on the side of the pick-up table facing the roll. The stripper is used to strip material from the strip and store it on the pick-up table.

[0011] In one embodiment, the material receiving assembly further includes a drive motor, the drive roller includes a driving roller and a driven roller, the driving roller and the driven roller rotate in opposite directions, the material belt is sandwiched between the driving roller and the driven roller, the output end of the drive motor is drivenly connected to the driving roller, and the cover film collecting roller and the bottom film collecting roller are drivenly connected to the driving roller respectively.

[0012] In one embodiment, the coil feeder device further includes a control console, which is disposed on the frame and electrically connected to the drive motor. The control console and the material handling platform are disposed at opposite ends of the frame, and the control console and the feeding assembly are located on the same side.

[0013] In one embodiment, the coil feeder device further includes a coil sensor, which is disposed on the frame and located on one side of the mounting shaft axis, and the coil sensor is communicatively connected to the control console.

[0014] In one embodiment, the mounting shaft, the cover film collecting roller, and the bottom film collecting roller are connected to the same side in the width direction of the frame.

[0015] This invention proposes a roll feeder device, including a frame, a feeding assembly, and a take-up assembly. The frame provides stable mounting support for the feeding and take-up assemblies, ensuring precise cooperation among components. The feeding assembly's mounting shaft houses the roll, and limiting components restrict axial displacement of the roll. The elastic fit of the roll allows for adaptive adjustment of the unloading tension, ensuring stable feeding of the material. The take-up assembly's drive roller drives the cover film collection roller and the bottom film collection roller to rotate synchronously via a circular belt, achieving synchronous waste collection. Even when speeds are inconsistent, a certain degree of mutual sliding can occur to maintain the material tension. This effectively solves the problems of easy roll deviation, unstable unloading tension, and messy waste collection in traditional feeding equipment, improving feeding stability and accuracy, reducing manual intervention, and enhancing the automation efficiency and production quality of the production line.

[0027] In the field of automated manufacturing, such as electronic component mounting, precision die-cutting, and label printing, roll feeder equipment is widely used. Roll feeder equipment is mainly used to smoothly and continuously transport strip or film rolls (usually including a base film, cover film, and the material being carried) to the processing station at a set speed and trajectory. It is one of the core basic equipment ensuring the efficient operation of automated production lines.

[0028] In actual industrial production, during the continuous operation of feeding equipment, it is often difficult to maintain an ideal transmission state when the material belt is transported from the unloading end to the collecting end. Due to a combination of factors, including the clearance between various transmission components, cumulative errors in the mechanical structure, and the continuous change in the diameter of the material roll itself during unwinding, the tension of the material belt along the transmission path fluctuates. This results in the material belt being easily subjected to uneven stretching or slack during transmission. Such fluctuations in transmission state directly disrupt the original force balance of the material belt, leading to abnormal phenomena such as belt deviation, wrinkling, localized jamming, or even belt breakage during travel. This forces frequent equipment shutdowns for manual intervention and adjustment, impacting production efficiency and product yield.

[0029] To solve the above problems, please refer to... Figures 1 to 5 This invention proposes a roll feeder device 100, including a frame 1, a feeding assembly 2, and a take-up assembly 3. The feeding assembly 2 includes a mounting shaft 21 and a limiting component 22. The mounting shaft 21 is connected to the frame 1 to accommodate the roll 200. The limiting component 22 is axially connected to the opposite ends of the mounting shaft 21 and forms a limiting space to restrict the axial displacement of the roll 200. The take-up assembly 3 includes a cover film collecting roller 31, a bottom film collecting roller 32, and a drive roller 33, which are spaced apart and connected to the frame 1. The cover film collecting roller 31 and the bottom film collecting roller 32 are respectively connected to the drive roller 33 via a circular belt drive. The rotation of the drive roller 33 drives the cover film collecting roller 31 and the bottom film collecting roller 32 to rotate synchronously. The roll 200 is elastically fitted onto the mounting shaft 21 and can rotate relative to the mounting shaft 21 to adjust the tension of the roll 200 during feeding.

[0030] The present invention provides a roll feeder 100, mainly applied to automated production lines for electronic component assembly, hardware parts processing, packaging and printing, etc. It is used to automatically feed, unload, peel off, and collect waste from roll materials, providing a stable and continuous material supply for subsequent processing steps. The roll feeder 100 includes a frame 1, a feeding assembly 2, and a receiving assembly 3. The frame 1 provides the installation foundation and support for the entire equipment; the feeding assembly 2 is used to install the roll 200 and achieve stable feeding; and the receiving assembly 3 is used to collect the cover film and bottom film after the roll is peeled off. These three components work together to achieve integrated automated feeding and waste recycling of roll materials, improving the automation level and production efficiency of the production line.

[0031] Frame 1, as the basic support component of the coil feeder 100, can bear the weight of the feeding assembly 2, the take-up assembly 3, and the coil 200, preventing the equipment from tipping over or shaking during operation and ensuring its stability. The dimensions of frame 1 are adapted to the production scenario and the specifications of the coil 200, with ample installation space to facilitate the installation, debugging, and subsequent maintenance of each component. The surface of frame 1 is treated with rust prevention to avoid corrosion during long-term use and extend the service life of the equipment. Frame 1 has multiple mounting holes and positioning structures to ensure precise installation of components such as the feeding assembly 2 and the take-up assembly 3, guaranteeing the accuracy of the fit between components and ensuring stable operation of the equipment.

[0032] The feeding assembly 2 includes a mounting shaft 21 and a limiting component 22. The mounting shaft 21 is connected to the frame 1 to accommodate the material roll 200. The mounting shaft 21 is made of a high-strength, wear-resistant metal material, preferably stainless steel or alloy steel, capable of withstanding the weight of the material roll 200 and the torque during the feeding process. The diameter of the mounting shaft 21 is matched with the inner diameter of the material roll 200, ensuring that the material roll 200 can be smoothly fitted onto the mounting shaft 21 without excessive looseness or jamming after fitting. The limiting component 22 is axially connected to the opposite ends of the mounting shaft 21 and forms a limiting space to restrict the axial displacement of the material roll 200. The limiting component 22 is made of the same metal material as the mounting shaft 21 and has sufficient strength to effectively prevent the material roll 200 from sliding or shifting axially along the mounting shaft 21 during the feeding process, ensuring the stability of the material roll 200 feeding and preventing the material belt from running off-center due to the offset of the material roll 200, which would affect the subsequent material stripping and feeding accuracy. The connection between the limiting component 22 and the mounting shaft 21 is firm, and is fixed by welding or bolts to prevent it from falling off during equipment operation and to ensure the stability of the limiting effect.

[0033] The material collection assembly 3 includes a cover film collecting roller 31, a bottom film collecting roller 32, and a drive roller 33, all spaced apart and connected to the frame 1. All three rollers are made of high-strength, smooth-surfaced metal, preferably aluminum alloy, to facilitate the winding and collection of the cover and bottom films, while reducing friction between the film and the rollers and preventing film damage. The cover film collecting roller 31 and the bottom film collecting roller 32 are respectively connected to the drive roller 33 via a circular belt drive. The circular belt is made of elastic, wear-resistant rubber to ensure stable power transmission during the transmission process. Utilizing the frictional transmission characteristics between the circular belt and the pulley, a certain degree of mutual sliding occurs when their speeds are inconsistent, maintaining belt tension. The rotation of the drive roller 33 drives the cover film collecting roller 31 and the bottom film collecting roller 32 to rotate synchronously, achieving synchronous collection of the cover and bottom films. This ensures that waste material after stripping is collected promptly and orderly, preventing waste accumulation from affecting equipment operation. The material roll 200 is elastically sleeved on the mounting shaft 21 and can rotate relative to the mounting shaft 21 to adjust the tension of the material roll 200 during feeding. This elastic sleeved method allows the material roll 200 to automatically adjust the rotational resistance according to actual needs during feeding, thereby adjusting the feeding tension and avoiding excessive tension that could cause the material belt to break, or insufficient tension that could cause the material belt to loosen or deviate, thus ensuring the stability of the feeding process.

[0034] The frame 1 provides stable mounting support for the feeding assembly 2 and the receiving assembly 3, ensuring precise coordination of all components. The mounting shaft 21 of the feeding assembly 2 houses the material roll 200, and the limiting component 22 restricts the axial displacement of the material roll 200. The elastic fit of the material roll 200 allows for adaptive adjustment of the feeding tension, ensuring stable feeding of the material belt. The drive roller 33 of the receiving assembly 3 drives the cover film collecting roller 31 and the bottom film collecting roller 32 to rotate synchronously via a circular belt, achieving synchronous waste recycling. When speeds are inconsistent, a certain degree of mutual sliding can occur to maintain the material belt tension. This effectively solves problems such as easy deviation of the material roll 200, unstable feeding tension, and messy waste recycling in traditional feeding equipment, improving the stability and accuracy of feeding, reducing manual intervention, and increasing the automation efficiency and production quality of the production line.

[0035] Furthermore, in one embodiment, please refer to Figure 4 and Figure 5 The mounting shaft 21 includes a rotating shaft 211 and a plurality of elastic diaphragms 212. The rotating shaft 211 is connected to the frame 1. Each elastic diaphragm 212 is spaced apart and connected to the circumference of the rotating shaft 211. The material roll 200 is clamped on the elastic diaphragm 212. The end of each elastic diaphragm 212 away from the rotating shaft 211 abuts against the inner circumferential wall of the material roll 200.

[0036] The rotating shaft 211, as the core support component for mounting shaft 21, is connected to the frame 1. Made of high-strength metal, it ensures stable support of the weight of the material roll 200 and the elastic diaphragm 212, while also possessing good rotational performance to facilitate synchronous rotation of the material roll 200 during the unloading process. Multiple elastic diaphragms 212 are spaced apart and connected circumferentially to the rotating shaft 211. These diaphragms are made of spring steel or rubber with good elasticity and wear resistance, possessing a certain degree of elastic deformation capability, allowing them to adaptively expand and contract according to the dimensions of the inner hole of the material roll 200. The material roll 200 is secured to the elastic diaphragm 212. The end of the elastic diaphragm 212 furthest from the rotating shaft 211 abuts against the inner circumferential wall of the material roll 200. The elastic force of the diaphragm 212 firmly fixes the material roll 200 to the rotating shaft 211, preventing slippage and free rotation during unloading, ensuring stable unloading. Furthermore, the tension of the material belt can be adjusted by the interaction between the material roll 200 and the spring diaphragm when the belt tension changes. For example, when the belt is too tight, the belt exerts a pulling force on the material roll 200, causing it to rotate relative to the spring diaphragm to a certain extent. When the belt is slack, the spring diaphragm pulls the belt through the engaging mechanism with the material roll 200, causing the slack section at the front to move a certain distance to achieve tension, and then pulls the material roll 200 to rotate the rotating shaft 211 normally. This achieves automatic tension adjustment of the material belt during transmission, ensuring normal conveying of the belt. Furthermore, the elastic deformation characteristics of the elastic diaphragm 212 allow the mounting shaft 21 to adapt to material rolls 200 with different inner hole sizes. Different specifications of material rolls 200 can be installed without replacing the mounting shaft 21, improving the versatility and ease of operation of the roll feeder 100. The spacing of the elastic diaphragm 212 ensures uniform force distribution on the material roll 200, preventing excessive localized force that could damage the inner hole of the material roll 200. Simultaneously, it ensures balanced force distribution during the rotation of the material roll 200, further enhancing the stability of the feeding tension and guaranteeing feeding accuracy.

[0037] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 4 as well as Figure 5 The limiting component 22 includes a first limiting plate 221 and a second limiting plate 222. The first limiting plate 221 is connected to the frame 1, and the second limiting plate 222 is sleeved on the rotating shaft 211 and can move axially relative to the rotating shaft 211 to adjust the distance between the first limiting plate 221 and the second limiting plate 222.

[0038] The first limiting plate 221 is fixedly connected to the frame 1 using bolts to ensure a secure connection and prevent displacement during equipment operation. The dimensions of the first limiting plate 221 are adapted to the width of the material roll 200, effectively preventing the material roll 200 from shifting towards the side closer to the frame 1. The second limiting plate 222 is sleeved on the rotating shaft 211, with a clearance fit between them to ensure flexible movement along the axial direction of the rotating shaft 211. The structure of the second limiting plate 222 is the same as that of the first limiting plate 221, and the two are arranged opposite each other to form a limiting space. By moving the second limiting plate 222, the distance between the first limiting plate 221 and the second limiting plate 222 can be adjusted so that the width of the limiting space matches the width of the material roll 200, ensuring that the material roll 200 is securely limited and preventing axial displacement. The movable design of the second limiting plate 222 improves the adaptability of the coil feeder 100 to coils 200 of different widths. When it is necessary to change to a coil 200 of different widths, only the position of the second limiting member 24 needs to be adjusted to adjust the width of the limiting space. In addition, the movable design of the second limiting plate 222 can avoid the limiting being too tight or too loose due to the width deviation of the coil 200. If the limiting is too tight, it will hinder the rotation of the coil 200 and affect the feeding; if the limiting is too loose, it will not play an effective limiting role, and the coil 200 will easily deviate. This structural design effectively solves this problem and ensures the stability of the feeding of the coil 200.

[0039] In another embodiment, please refer to Figure 4 and Figure 5 The feeding assembly 2 also includes a fixing member 23 and a plurality of limiting members 24. Each limiting member 24 is connected to the side of the second limiting plate 222 facing away from the first limiting plate 221 and is distributed circumferentially along the rotation axis 211. A deformation space is formed between two adjacent limiting members 24. An elastic diaphragm 212 is disposed in the deformation space. The fixing member 23 passes through a limiting member 24 and is screwed to it. The fixing member 23 can rotate relative to the limiting member 24 to abut against the rotation axis 211 to fix the second limiting plate 222.

[0040] Multiple limiting members 24 are circumferentially spaced along the rotation axis 211 and connected to the side of the second limiting plate 222 facing away from the first limiting plate 221. The limiting members 24 are made of the same material as the second limiting plate 222 and are integrally formed with or bolted to the second limiting plate 222 to ensure a secure connection. The specific choice can be made according to actual needs. Specifically, in this embodiment, there are three elastic diaphragms 212 and three limiting members 24, which are circumferentially spaced along the rotation axis 211 and connected to the second limiting plate 222. In other embodiments, the number of elastic diaphragms 212 and limiting members 24 can be two, four, or more, depending on actual needs. The deformation space formed between adjacent limiting members 24 has a width greater than the thickness of the elastic diaphragm 212, allowing the elastic diaphragm 212 to have a certain deformation space within the limiting space. The elastic diaphragm 212 is disposed within the deformation space. The limiting member 24 can limit and protect the elastic diaphragm 212, preventing excessive bending or damage to the elastic diaphragm 212 during deformation and ensuring the service life of the elastic diaphragm 212. The fixing member 23 can be a bolt, through which one of the limiting members 24 is threaded and screwed. The end of the fixing member 23 can abut against the rotating shaft 211. When the second limiting plate 222 is adjusted to a suitable position, the fixing member 23 is rotated so that the end of the fixing member 23 abuts against the rotating shaft 211. The second limiting plate 222 is firmly fixed to the rotating shaft 211 by friction, preventing it from moving axially. This structural design makes the fixation of the second limiting plate 222 more precise and secure. At the same time, the limiting component 24 protects the elastic diaphragm 212, ensuring that the elastic diaphragm 212 can stably exert its elastic function. This not only ensures the limiting effect of the material roll 200, but also ensures the stable adjustment of the unloading tension of the material roll 200, further improving the structural reliability and operational stability of the equipment.

[0041] Furthermore, in one embodiment, please refer to Figure 1 , Figure 2 as well as Figure 3 The roll feeder device 100 also includes a correction roller 4, which is connected to the frame 1 and is located vertically between the cover film collecting roller 31 and the bottom film collecting roller 32. Both ends of the correction roller 4 are provided with third limiting plates 41, which can be adjusted relative to the axial direction of the correction roller 4.

[0042] The guide roller 4 is designed to correct belt deviation during transport, ensuring stable transport along a preset trajectory and guaranteeing the accuracy of subsequent material stripping and feeding. Connected to the frame 1, the guide roller 4 can rotate flexibly. As the belt passes over its surface, it guides the belt back to the correct transport trajectory when deviation occurs. Vertically positioned between the cover film collecting roller 31 and the bottom film collecting roller 32, the guide roller 4 effectively receives the belt after it is fed from the feeding assembly 2, while also providing guidance for the separation and collection of the cover and bottom films, ensuring smooth belt transport. Specifically, the cover film collecting roller 31 is located above the guide roller 4, and the bottom film collecting roller 32 is located below it, facilitating the separation and collection of the cover and bottom films after the belt passes through the rollers. The cover film, which covers the bottom film, is conveyed upwards and collected by the rotating cover film collecting roller 31. The bottom film continues to be conveyed forward to peel off the material on it, which is finally collected by the bottom film collecting roller 32. The guide roller 4 has a third limiting plate 41 at both ends of its axial direction. The third limiting plate 41 is sleeved on the guide roller 4 and can be adjusted and moved along the axial direction of the guide roller 4. By adjusting the distance between the two third limiting plates 41, it can accommodate material strips of different widths, preventing the material strip from deviating along the axial direction of the guide roller 4. The adjustable design of the third limiting plate 41 allows the guide roller 4 to adapt to material strips of different specifications, further improving the versatility of the roll feeder 100. It also ensures that the material strip remains centered during transmission, avoiding problems such as inaccurate material peeling and messy waste collection caused by material strip deviation, thus ensuring the stability and accuracy of the feeding process.

[0043] In one embodiment, please refer to Figure 1 , Figure 2 as well as Figure 3 The coil feeder 100 also includes a stripper 5 and a feeding platform 6. The stripper 5 is positioned facing the coil 200 and is located on the side of the feeding platform 6 facing the coil 200. The stripper 5 is used to strip the material from the feeder and store it on the feeding platform 6.

[0044] The stripping blade 5 and the feeding platform 6 enable automatic stripping and storage of materials, further enhancing the automation level of the coil feeder 100, reducing manual intervention, and improving production efficiency. The stripping blade 5 is made of high-hardness, wear-resistant metal material with a sharp, blunted blade, enabling it to quickly and accurately strip material from the conveyor belt without damaging the material or the belt, ensuring material integrity. The stripping blade 5 faces the coil 200, its position adapted to the conveyor belt's trajectory. As the belt passes the stripping blade 5, its blade inserts between the material and the belt, stripping the material from the belt. The stripped material falls onto the feeding platform 6 under gravity. The feeding platform 6, made of flat, smooth metal or plastic sheeting, is located below the stripping blade 5 and stores the stripped material. The size of the feeding platform 6 is adapted to the material specifications, ensuring neat storage and facilitating retrieval in subsequent processes. The height of the material handling platform 6 is reasonably designed to facilitate material handling by operators or automated equipment. The platform also features an anti-slip structure to prevent material from sliding or piling up when falling. The cooperation between the peeling blade 5 and the material handling platform 6 achieves integrated material peeling and storage, eliminating the need for manual peeling and collection, reducing labor intensity, improving production efficiency, and ensuring the accuracy and integrity of material peeling, thus enhancing production quality.

[0045] Further, please refer to Figure 2 The receiving assembly 3 also includes a drive motor 34, and the drive roller 33 includes a drive roller 331 and a driven roller 332. The drive roller 331 and the driven roller 332 rotate in opposite directions. The material belt is clamped between the drive roller 331 and the driven roller 332. The output end of the drive motor 34 is connected to the drive roller 331 for transmission. The cover film collecting roller 31 and the bottom film collecting roller 32 are respectively connected to the drive roller 331 for transmission.

[0046] The drive motor 34, serving as the power source for the entire receiving assembly 3, is a speed-adjustable stepper motor or servo motor. It can precisely adjust its speed according to the feeding speed, ensuring that the collection speed of the cover film and bottom film matches the feeding speed, preventing the material belt from becoming slack or taut. The drive roller 331 and driven roller 332 rotate in opposite directions, forming a clamping space within which the material belt is held. When the drive roller 331 rotates, friction drives the driven roller 332 to rotate synchronously, simultaneously propelling the material belt forward and providing stable power for its transport. The output end of the drive motor 34 is connected to the drive roller 331 via a belt drive, ensuring stable power transmission and preventing slippage. The cover film collecting roller 31 and the bottom film collecting roller 32 are respectively connected to the drive roller 331 via a circular belt drive. When the drive roller 331 rotates, it synchronously drives the cover film collecting roller 31 and the bottom film collecting roller 32 to rotate, realizing the synchronous collection of the cover film and the bottom film. This ensures that the waste material after the material strip is peeled off can be recycled in a timely manner, avoiding the accumulation of waste material that affects the material strip transmission. Through the setting of synchronous belt and belt drive, only one drive component is needed to realize the synchronous movement of the material receiving component 3. The simplified drive structure, and through the transmission of the circular belt, allows the drive roller 33, the cover film collecting roller 31, and the bottom film collecting roller 32 to slide against each other when their speeds are inconsistent, thereby maintaining the material strip tension and ensuring the normal feeding and recycling of the material roll 200. This structural design enables the material strip transmission and waste collection to be synchronized and linked, ensuring stable power transmission, ensuring the continuity and stability of the feeding process, and further improving the automation level and production efficiency of the roll feeder feeding equipment 100.

[0047] In one embodiment, please refer to Figure 1 , Figure 2 as well as Figure 3 The coil feeder feeding device 100 also includes a control console 7, which is located on the frame 1 and electrically connected to the drive motor 34. The control console 7 and the material handling table 6 are located at opposite ends of the frame 1, and the control console 7 and the feeding assembly 2 are located on the same side.

[0048] The control console 7 is designed for centralized control of the equipment, enhancing operational convenience. Its rational layout facilitates operation and monitoring of the equipment's running status. The control console 7 features a waterproof and dustproof casing and houses the control circuitry and operation panel. The panel includes a power switch, speed adjustment buttons, and an emergency stop button. Operators can precisely adjust the speed of the drive motor 34, control the start and stop of the equipment, and monitor its operating status in real time. The control console 7 is mounted on the frame 1 and electrically connected to the drive motor 34. Control signals are transmitted via wires, ensuring rapid and accurate transmission of control commands and enabling precise control of the drive motor 34's speed. This, in turn, adjusts the conveyor belt speed and waste collection speed to adapt to different production needs. The control console 7 and the unloading platform 6 are positioned at opposite ends of the frame 1 to prevent accidental contact during material handling, ensuring operational safety. The control console 7 is located on the same side as the feeding assembly 2, allowing operators to simultaneously operate the control console 7 when changing the material roll 200 or adjusting the limit components 22, reducing operational steps and improving efficiency. The design of the console 7 takes into account both ease of operation and safety. The reasonable layout design further enhances the practicality and operating comfort of the equipment, making it suitable for the needs of industrialized automated production.

[0049] Further, please refer to Figure 2 The coil feeder device 100 also includes a coil sensor 8, which is located on the frame 1 and on one side of the mounting shaft 21. The coil sensor 8 is communicatively connected to the control console 7.

[0050] The material roll sensor 8 is configured to monitor the remaining amount of material roll 200 in real time. It issues a timely reminder when material roll 200 is about to run out, preventing production line interruptions due to insufficient material roll 200 and improving production continuity. The material roll sensor 8 uses an infrared sensor or proximity sensor, mounted on the frame 1 and located on one side of the mounting shaft 21, with its sensing direction aligned with the material roll 200. It can detect changes in the diameter of the material roll 200 in real time, thereby determining the remaining amount. The material roll sensor 8 communicates with the control console 7 using wired or wireless communication to ensure stable signal transmission. When the diameter of the material roll 200 decreases to a preset threshold, the material roll sensor 8 sends a signal to the control console 7, which then issues an audible and visual alarm, reminding the operator to replace the material roll 200 in time. This design provides early warning of insufficient material roll 200, giving operators ample time to replace it, preventing production line interruptions due to insufficient material roll 200, reducing production losses, and improving production efficiency. Meanwhile, the installation of the material roll sensor 8 eliminates the need for manual observation of the remaining amount of material roll 200 in real time, reducing manual labor intensity, improving the automation and intelligence level of the equipment, and further adapting to the needs of automated production lines.

[0051] In one embodiment, please refer to Figure 2 The mounting shaft 21, the cover film collecting roller 31, and the bottom film collecting roller 32 are connected to the same side of the frame 1 in the width direction.

[0052] The mounting shaft 21, the cover film collecting roller 31, and the bottom film collecting roller 32 are all connected to the same side of the frame 1 in the width direction, forming a triangular distribution. This avoids mutual interference between components and reduces the space occupied by the equipment in the width direction, making it suitable for production workshops of different sizes. Furthermore, the roll feeder 100 in this embodiment has an open structure, facilitating the replacement of the roll 200 and handling the winding of the material belt. With all components centrally installed on the same side, operators can complete the installation and debugging of the roll 200 without moving back and forth when changing it. Cleaning up waste cover film and bottom film can also be done centrally, reducing operational steps and improving work efficiency. Simultaneously, the centralized layout shortens the transmission distance between components, makes the length of the circular belt more reasonable, reduces slippage and energy loss during transmission, ensures more stable power transmission, and improves the operational stability of the roll feeder 100.

[0053] Specifically, during the conveyor belt transport process, the control console 7 and the feeding assembly 2 are located on the same side of the frame 1 along its length, facilitating the replacement and adjustment of the material roll 200. A guide roller 4 and a cover film collection roll are positioned in the middle to facilitate the separation and collection of the cover film. After the material roll 200 passes through the guide roller 4, the cover film separates from the bottom film. The cover film is then conveyed to the upper cover film collection roller 31 for rotational collection. The bottom film continues to move to the position of the peeling blade 5 to peel off the material. An anti-deviation channel at the guide roller 4 prevents the conveyor belt from skewing, which would affect material peeling. A peeling blade 5 and a picking platform 6 are located at the end of the frame 1. After passing through the peeling blade 5, the conveyor belt is pulled back, and the material continues to move forward to achieve material peeling, moving the material to the picking platform 6. The picking platform 6 is made of non-stick material, facilitating material retrieval by the robotic arm. After the bottom film is pulled back, it is stuck inside the drive roller 33. The drive roller 33 consists of an active roller 331 and a driven roller 332 that press against each other, providing sufficient friction to drive the entire conveyor belt. After the bottom film comes out, it passes through the bottom film collection roller 32 for collection. This solution maintains stable belt tension through the elastic design of the feeding component 2 and the combination of synchronous belt and round belt; it uses a single drive motor 34 to drive all units, making control simple and convenient, without complex circuit distribution, simplifying the structure of the coil feeder 100. The open structure also facilitates the replacement of the coil 200 and the handling of belt winding, improving the practicality and applicability of the coil feeder 100.
