[0040] In order to make the technical problems, technical solutions and beneficial effects solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0041] Example 1: Please refer to Figures 1 to 8 The present embodiment provides an automated film coil packaging production line, comprising a film coil packaging preparation area 1 for packaging film coils, and an adjacent film coil stacking and packaging area 2 for packaging film coils. The film coil stacking and packaging area 2 can stack film coils in a single layer or double layer.

[0042] The film roll stacking and packaging area 2 includes a stacking mechanism 21 for stacking film rolls on a pallet, one side of which is adjacent to the film roll packaging preparation area 1; a first conveyor belt 22 for transporting the stacked film roll group, adjacent to the other side of the stacking mechanism 21; a second conveyor belt 23, adjacent to one end of the first conveyor belt 22, for transporting the stacked film roll group, a horizontal strapping machine 231 is provided on the second conveyor belt 23, and a cover plate loading machine 232 is provided next to the horizontal strapping machine 231; a third conveyor belt 24, adjacent to one end of the second conveyor belt 23, for transporting the finally packaged film roll group, a vertical strapping machine 241 is provided on the third conveyor belt 24, and a stretch film machine 242 is provided next to the vertical strapping machine 241. A finished product information labeling machine 243 is provided next to the end of the third conveyor belt 24; a first transfer device 25 is adjacent to one side of the stacking mechanism 21, and is used to transfer the stacked film roll group on the stacking mechanism 21 to the first conveyor belt 22; a second transfer device 26 is adjacent to the other side of the stacking mechanism 21, and can transfer the film roll group on the first conveyor belt 22 to the second conveyor belt 23, and can also directly transfer the stacked film roll group on the stacking mechanism 21 to the second conveyor belt 23; a stacking return conveying device 27, one side of which is provided between the second conveyor belt 23 and the third conveyor belt 24, and the other side can return the stacked film roll group to the stacking mechanism 21 for double-layer stacking through the second transfer device 26.

[0043] In this embodiment, the automated film coil packaging production line sequentially includes a film roll packaging preparation area 1 and a film roll palletizing and packaging area 2. After a single film roll completes packaging processing in the film roll packaging preparation area 1, it enters the film roll palletizing and packaging area 2 for subsequent palletizing and packaging operations.

[0044] In the film roll stacking and packaging area 2, the film rolls are first stacked by the stacking mechanism 21 and neatly placed on the pallet. This step realizes the automatic stacking of the film rolls, greatly improving the stacking efficiency and stacking quality.

[0045] The stacked film roll group is then transferred by the first transfer device 25 to the first conveyor belt 22, and then transferred by the second transfer device 26 to the second conveyor belt 23. On these two conveyor belts, the film roll group can be transported smoothly, realizing the automatic flow of the film roll group between different processes. Specifically, the first transfer device 25 and the second transfer device 26 can be transfer trolleys that move linearly on fixed rails, and cooperate with the stacking mechanism 21 to realize the transportation and flow of the film roll group. It should be noted that in this embodiment, the second transfer device 26 can transfer the film roll group on the first conveyor belt 22 to the second conveyor belt 23, and can also directly transfer the stacked film roll group on the stacking mechanism 21 to the second conveyor belt 23, eliminating the waiting time on the first conveyor belt and further improving production efficiency.

[0046] When the film rolls reach the second conveyor belt 23, they are horizontally strapped by a horizontal strapping machine 231. Simultaneously, a cover sheet loading machine 232 places a cover sheet over the rolls to protect them from damage during subsequent transport. This step enables automatic strapping and cover sheet placement, further improving the production line's automation and efficiency.

[0047] Next, the film rolls are transported to the third conveyor belt 24, where the vertical strapping machine 241 bundles the rolls vertically. The stretch film machine 242 wraps a protective film around the rolls to enhance their overall stability and protect them from moisture and dust. Finally, the finished product labeling machine 243 affixes labels containing product information, both standard and RFID, to the rolls for easy tracking and management. This step completes the final packaging of the film rolls, ensuring that the products meet factory standards.

[0048] Furthermore, the palletizing return conveyor 27 and the second transfer device 26 in this embodiment together form a return system. When double-layer palletizing is required, the second transfer device 26 can return the single-layer palletized film rolls via the palletizing return conveyor 27 to the palletizing mechanism 21 for a second palletizing operation. This design allows the production line to flexibly respond to varying palletizing requirements, improving its adaptability and flexibility.

[0049] In summary, the automated film coil packaging production line provided in this embodiment achieves full automation of the entire production process, from film coil packaging to palletizing and packaging, through the synergistic effect of a series of automated equipment. This not only significantly improves production efficiency and reduces labor costs, but also enhances product quality and consistency. Furthermore, the design of the reflow system enables the production line to better meet the personalized needs of customers.

[0050] Furthermore, as a preferred embodiment of the present invention but not a limitation, the stacking return conveying device 27 includes a first rotating conveyor 271 arranged between the second conveyor belt 23 and the third conveyor belt 24, the first rotating conveyor 271 is connected to a second transplanter 272, the second transplanter 272 is connected to a second rotating conveyor 273, the second rotating conveyor 273 is connected to a fourth conveyor belt 274, and the fourth conveyor belt 274 can cooperate with the second transfer device 26 to return the stacked film roll group to the stacking mechanism 21.

[0051] In this embodiment, the palletizing return conveyor 27 is a key component that enables the production line to flexibly handle double-layer palletizing requirements. Specifically, the palletizing return conveyor 27 comprises a first rotary conveyor 271 positioned between the second conveyor belt 23 and the third conveyor belt 24. The first rotary conveyor 271 rotates to adjust the conveying direction of the film rolls, facilitating subsequent return operations.

[0052] The first rotary conveyor 271 is connected to a second transfer machine 272, which is responsible for ensuring the smooth transfer of the film roll group to the second rotary conveyor 273. The second rotary conveyor 273 also has a rotation function, which can further adjust the conveying direction of the film roll group to meet the needs of returning to the palletizing mechanism 21. The coordinated action of the first rotary conveyor 271 and the second rotary conveyor 273 ensures that the film roll group can flexibly adjust its direction during the return process to adapt to the layout of the production line and palletizing requirements.

[0053] Finally, the second rotary conveyor 273 is connected to a fourth conveyor belt 274, which cooperates with the second transfer device 26 to return the palletized film rolls to the palletizing mechanism 21. During this step, the fourth conveyor belt 274 smoothly transports the film rolls into the range of movement of the second transfer device 26, which then accurately receives and transfers the film rolls back to the palletizing mechanism 21, completing the entire reflow process.

[0054] By utilizing the palletizing return conveyor 27, the automated film coil packaging production line provided by this embodiment can efficiently and accurately achieve double-layer palletizing. This not only improves the adaptability and flexibility of the production line, but also further enhances production efficiency and product quality. Furthermore, this design reduces the complexity and error rate of manual operations.

[0055] Furthermore, as a preferred embodiment of the present invention but not a limitation, the stacking mechanism 21 includes a robotic arm 211 for taking and placing film rolls, and a slide rail is slidably connected to the bottom of the robotic arm 211. Both sides of the robotic arm 211 are respectively provided with a first transplanter 212 for stacking. The first transplanter 212 can cooperate with the first transfer device 25 and the second transfer device 26 to transfer the film roll group.

[0056] In this embodiment, the stacking mechanism 21 is responsible for accurately stacking the film rolls for subsequent packaging and transportation. In this mechanism, the robot arm 211 preferably uses a six-axis robot arm, which can flexibly pick up and place the film rolls, ensuring that each film roll is accurately placed in the predetermined position.

[0057] Multiple first transfer machines 212 are located on either side of the robotic arm 211. Each of the first transfer machines 212 has a tray feeder located near the second transfer device 26. This tray feeder can work with the second transfer device 26, or the second transfer device 26 can work with the first transfer device 25 via a first conveyor belt. A tray for carrying film rolls is positioned above the first transfer machine 212. The first transfer machines 212 work closely with the first and second transfer devices 25, 26 to ensure smooth transfer of film rolls from one production line to another, or from one production line to a storage area.

[0058] Specifically, after a film roll arrives from the film roll packaging preparation production line, a robotic arm 211 precisely grasps the roll and places it on a pallet on the first transfer machine 212. Subsequently, depending on production needs, the first transfer machine 212 transfers the palletized film roll assembly to the first transfer device 25 or the second transfer device 26. These transfer devices then transport the film roll assembly to the next process or conveyor belt.

[0059] Through the above design, the stacking mechanism 21 not only improves the accuracy and efficiency of stacking, but also makes the entire production line more flexible and efficient. In addition, due to the reduction of manual intervention, operating errors and labor costs are also greatly reduced.

[0060] Furthermore, as a preferred embodiment of the present invention but not a limitation thereof, the film roll packaging preparation area 1 includes a gripping mechanism 51 for gripping the film roll; a front conveyor belt 52, located below the gripping mechanism 51, for transporting the slit film roll, and a manual packaging table is also connected to the length direction of the front conveyor belt 52 for emergency use; a hot melt mechanism 53, located below the gripping mechanism 51 and adjacent to the front conveyor belt 52 on one side, for weighing and sealing the film roll, the hot melt mechanism 53 includes a hot melt table 531 for sealing and packaging the film roll, and an unwinding machine 5 is provided next to the hot melt table 531 to provide it with packaging film. 32; a fastening mechanism 54, located below the gripping mechanism 51 and adjacent to the hot-melt mechanism 53 on one side, for fastening end caps to both ends of the film roll, the fastening mechanism 54 comprising an end cap feeding device and an end cap fastening device; a turning mechanism 55, adjacent to the hot-melt mechanism 53 on one side and adjacent to the film roll stacking and packaging area 2 on the other side, for adjusting the film roll from horizontal to vertical placement; a paper core labeling machine 56, adjacent to one end of the front conveyor belt 52, for labeling the paper core of the slit film roll before it enters the front conveyor belt 52; a film roll labeling machine 57, adjacent to the turning mechanism 55, for surface labeling of the film roll after packaging.

[0061] In this embodiment, a front conveyor belt 52 is located below the gripping mechanism 51 to transport film rolls cut to preset sizes. A centering device can be installed on the front conveyor belt 52 to ensure smooth delivery of the film rolls to the subsequent packaging process. It should be noted that a manual packaging station is also connected to the length of the front conveyor belt 52. This allows for manual packaging in the event of a malfunction in the automated production line or when special operations are required, providing greater flexibility in production operations.

[0062] Adjacent to the front conveyor belt 52 is the hot melt mechanism 53, which is responsible for weighing and sealing the film rolls. This step is crucial to ensuring product quality, as it ensures that each film roll meets the specified weight standard and is effectively sealed to prevent external contamination. The hot melt mechanism 53 includes a hot melt station 531 and an unwinder 532. The former is used to seal and package the film rolls, while the latter is responsible for providing auxiliary packaging materials such as bubble film.

[0063] The snap-fit ​​mechanism 54 is located below the gripping mechanism 51 and adjacent to the hot melt mechanism 53 on one side. It is used to snap the end caps onto the ends of the film roll, improving the sealing and moisture-proof performance of the individual film rolls. The snap-fit ​​mechanism 54 may include an end cap feeding device and an end cap snap-fitting device, which work together to ensure that each end cap is accurately snapped onto the film roll.

[0064] The flip mechanism 55 is located between the hot melt mechanism 53 and the film roll stacking and packaging area 2. Its function is to adjust the horizontal film roll to a vertical position to facilitate subsequent stacking and packaging operations. This design greatly saves space and improves the compactness and efficiency of the production line.

[0065] In addition, the paper core labeling machine 56 and the film roll labeling machine 57 are also important components of the film roll packaging preparation area 1. The paper core labeling machine 56 labels the paper core of the slit film roll before it enters the front conveyor belt 52, facilitating product tracking and management. The film roll labeling machine 57 is responsible for labeling the surface of the individual film rolls after packaging.

[0066] Furthermore, as a preferred embodiment of the present invention but not a limitation, the grabbing mechanism 51 includes a frame 511, and the frame 511 is provided with a first grabbing device 512 for transferring the film roll on the front conveyor belt 52 to the hot melt mechanism 53. A second grabbing device 513 is provided next to the first grabbing device 512, and the second grabbing device 513 is a linked grabbing structure, which is used to transfer the film roll on the hot melt mechanism 53 to the fastening mechanism 54 while simultaneously transferring the film roll on the fastening mechanism 54 to the flipping mechanism 55.

[0067] In this embodiment, the grasping mechanism 51 includes a stable frame 511, which not only provides stable support for the entire grasping mechanism, but also ensures accuracy and stability during the grasping process.

[0068] On the frame 511, a first gripping device 512 is first provided to accurately transfer the film roll from the front conveyor belt 52 to the hot melt mechanism 53. The first gripping device 512 can adopt a holding or clamping gripping structure, preferably a clamping structure, which connects to the paper core holes at both ends of the film roll to achieve clamping. Compared with the holding gripping structure, it can effectively avoid damage to the side of the film roll. Furthermore, a pressure sensor and servo system can be provided on the gripping mechanism 51 to ensure that the gripping mechanism has moderate force during operation, ensuring the integrity of the film roll and placing it stably on the hot melt mechanism 53 to prepare for subsequent weighing and sealing.

[0069] In addition to the first gripping device 512, the frame 511 is also provided with a second gripping device 513, which is also preferably a clamping mechanism. Unlike the first gripping device 512, the second gripping device 513 utilizes a linked gripping structure. Specifically, the second gripping device 513 may include two parallel gripping structural units. The two gripping structural units can be linked together by providing a synchronization mechanism, such as a connecting rod mechanism, a synchronous belt mechanism, or a motor drive mechanism. This structure enables the second gripping device 513 to simultaneously transfer the film roll from the hot melt mechanism 53 to the fastening mechanism 54 while simultaneously transferring the film roll that has already been fastened on the fastening mechanism 54 to the flipping mechanism 55, greatly improving the efficiency and automation of the production line. Through the coordinated operation of the first gripping device 512 and the second gripping device 513, the gripping mechanism 51 can ensure the smooth flow of film rolls between the various processes in the packaging preparation area 1, thereby reducing waiting time and human intervention, and further improving the overall performance of the production line.

[0070] Furthermore, as a preferred embodiment of the present invention but not a limitation, a packaging labeling machine 244 for labeling the surface of the film roll packaging is provided on one side of the third conveyor belt 24 near the end, and a positioning track 245 that can match the bottom of the pallet is provided along the length direction of the third conveyor belt 24 to ensure consistency of the transportation route.

[0071] After the film rolls have gone through a series of packaging preparation processes, they are transported to the film roll palletizing and packaging area 2 for final palletizing and packaging. In this process, to ensure that each film roll package can be clearly labeled, this embodiment adds a packaging labeling machine 244 to the side near the end of the third conveyor belt 24.

[0072] The primary function of the packaging labeler 244 is to apply labels to the surface of film roll packaging. These labels can contain various product information, such as production date, batch number, specifications, and origin, and are crucial for product tracking, management, and sales. Automated labeling not only improves labeling accuracy and efficiency, but also reduces human error, ensuring accurate label information.

[0073] Furthermore, as a preferred embodiment of this solution, but not a limitation, the automated film roll packaging production line proposed in this example utilizes multiple high-performance servo motors in its control system. These servo motors, through sophisticated control algorithms and carefully designed communication protocols, ensure high-precision execution and efficient coordination among various mechanisms on the production line. Applied to various processes, including film roll gripping, conveying, palletizing, and strapping, they ensure smooth production processes and stable and reliable product quality.

[0074] In addition, the production line is also equipped with an advanced main control system with powerful data computing capabilities and high reliability. The system can process feedback data from each servo motor in real time and issue corresponding instructions according to the preset control logic to achieve comprehensive monitoring and precise control of the production line.

[0075] To ensure operational convenience, the production line features a variety of operating modes, including fixed operating consoles and handheld mobile devices (such as tablets), allowing production personnel to flexibly choose according to actual conditions. Furthermore, the production line also features remote monitoring and maintenance capabilities, allowing engineers to view the line's operating status in real time through remote connections, identifying and resolving issues promptly without having to visit the site.

[0076] In terms of fault diagnosis and recovery, the production line proposed in this embodiment also features a fault diagnosis module that monitors and displays equipment fault information in real time, helping production personnel quickly locate the problem and take appropriate measures. Once the fault is resolved, the production line can quickly resume normal operation, ensuring stable production efficiency and product quality.

[0077] Example 2: Please refer to Figures 1 to 8 , this embodiment provides a film roll packaging production process, comprising the following steps:

[0078] S1, the size of the film roll after slitting is measured, and the film roll whose size meets the order information requirements is labeled with a paper core.

[0079] In this step, the roll diameter and length of the slit film roll are first measured. This ensures the consistency between the incoming material and the order information sent by the MES system. High-precision measuring equipment, such as a laser rangefinder or roll diameter measuring instrument, accurately captures the roll diameter and length data. The measured data is then compared with the order information in the MES system. If the data matches, the incoming material meets the order requirements, and the subsequent paper core labeling process can proceed.

[0080] If the measured data is inconsistent with the order information in the MES system, the alarm system will be triggered immediately, issuing an alert. This inconsistency may be caused by errors in the slitting process, material mix-up, or other reasons. With timely alarm notifications, operators can take prompt measures, such as checking the slitting equipment, verifying material information, or adjusting the order data, to ensure normal operation of the production line and product quality.

[0081] The film roll, whose dimensions match the order information, is then sent to the paper core labeler 56. This machine applies a label to the paper core of the film roll. The label typically contains basic product information, such as the production date and batch number. This step facilitates subsequent tracking and management.

[0082] S2: The film roll that has completed step S1 is transferred to the front conveyor belt 52 and the film roll is centered. In this step, after the paper core is labeled, the film roll is automatically transferred to the front conveyor belt 52. During the conveying process, the front conveyor belt 52 will align the film roll to ensure that the film roll remains stable during transportation and provides accurate positioning for subsequent processes.

[0083] S3, using the first grabbing device 512 to grab the film roll in step S2 to the hot melt table 531, and the unwinding machine 532 cooperates with the hot melt table 531 to seal and package the surface of the film roll, and weigh it after packaging.

[0084] In this step, when the front conveyor belt 52 delivers the film roll to the designated location, the first gripping device 512 activates, precisely grabbing the film roll and placing it on the hot-melt station 531. Simultaneously, the unwinder 532 begins operating, providing the hot-melt station 531 with the required packaging film. The hot-melt station 531 seals the film roll surface, ensuring its airtightness, moisture resistance, and shock absorption. After packaging, the hot-melt mechanism 53 also weighs the film roll to ensure that each roll meets the specified weight standard.

[0085] S4, using the second gripping device 513 to move the film roll that has completed step S3 to the fastening mechanism 54, and then using the fastening mechanism 54 to set end caps on both ends of the film roll.

[0086] After sealing, packaging, and weighing, the second gripping device 513 is activated, grabbing the film roll from the hot melt station 531 and transferring it to the fastening mechanism 54. The fastening mechanism 54 comprises an end cap feeding device and an end cap fastening device, which work together to attach end caps to each end of the film roll. The end caps not only enhance the film roll's aesthetics but also further improve its sealing and moisture-proof properties, while also preventing damage.

[0087] S5. While using the second gripping device 513 to move the film roll that has completed step S3 to the fastening mechanism 54, the second gripping device 513 can also move the film roll that has completed step S4 to the flipping mechanism 55, and use the flipping mechanism 55 to flip the horizontally placed film roll to a vertical position, and then use the film roll labeling machine 57 to label the surface of the packaged film roll.

[0088] In this step, as the second gripping device 513 grabs a new film roll from the hot melt station 531 and transfers it to the fastening mechanism 54, it also simultaneously grabs the film roll with the end cap fastened from the fastening mechanism 54 and transfers it to the flipping mechanism 55. The flipping mechanism 55 flips the horizontal film roll to a vertical position to facilitate subsequent palletizing and packaging operations. The film roll is then sent to the film roll labeling machine 57 for surface labeling. The label typically contains detailed information about the produced film roll, a barcode, and other information, facilitating production tracking and management.

[0089] In step S6, the film rolls packaged and labeled in step S5 are palletized and packaged according to a pre-set combination, ultimately outputting the finished packaged film roll group. The final step involves palletizing and packaging the packaged and labeled film rolls according to a pre-set combination. This step is completed in the film roll palletizing and packaging area 2. Automated palletizing equipment and packaging machinery combine multiple film rolls into a single film roll group and then package them. The resulting packaged film roll group not only facilitates storage and transportation but also provides enhanced product protection.

[0090] Furthermore, as a preferred implementation of this solution but not limiting, step S6 specifically further includes:

[0091] S61, using the robot arm 211 to stack the film rolls that have been packaged and labeled in step S5 onto the pallet of the first transplanter 212 in a preset combination until the pallet is fully loaded with the film roll group.

[0092] In this step, robotic arm 211 precisely stacks the film rolls packaged and labeled in step S5 onto the pallets of first transplanter 212 in a pre-set arrangement, such as groups of five rolls. This automated process ensures that the film rolls on each pallet are neatly arranged and balanced in weight. When the number or weight of film rolls on a pallet reaches a pre-set value, the pallet is considered fully loaded, forming a roll group.

[0093] S62, using a transfer device to transfer the stacked film roll group to the conveyor belt, and then sequentially through the horizontal strapping machine 231 and the cover plate loading machine 232 to complete the horizontal strapping and top cover plate setting of the film roll group.

[0094] In this step, a transfer device, such as the first and second transfer devices described in Example 1, is used to transfer a fully loaded pallet, i.e., a film roll assembly, from the first transfer device 212 to the conveyor belt. The film roll assembly then passes through the horizontal strapping device 231 on the conveyor belt for horizontal strapping, ensuring that the film roll assembly does not become loose during transport. The film roll assembly then passes through the cover plate loading device 232 on the conveyor belt, which automatically sets a top cover plate to protect the top of the film roll assembly from damage.

[0095] S630, the film roll group that has been horizontally bundled and the top cover plate set is rotated to the first transplanter 212 through the stacking return conveying device 27 and the second transfer device 26, and the upper end surface of the film roll group serves as a base for the second stacking.

[0096] In this step, the film roll group that has completed the initial packaging is rotated to the first transplanter 212 through the stacking return conveyor 27 and the second transfer device 26. At this time, the upper end surface of the film roll group serves as a base for the second stacking, ready for secondary stacking.

[0097] S631, use the robot arm 211 to perform secondary palletizing on the film roll group according to a preset combination method.

[0098] Specifically, in the step, the robot arm 211 is used again to perform secondary stacking on top of the film roll group that has completed the preliminary packaging according to the first preset combination method to form a double-layer film roll group.

[0099] S632, use the transfer device to transfer the film roll group that has completed the secondary stacking to the conveyor belt, and then use the horizontal strapping machine 231 and the cover plate loading machine 232 to complete the horizontal strapping of the upper film roll group and the setting of the top cover plate respectively.

[0100] In this step, the double-layer film roll group is transferred to the conveyor belt using a transfer device, and then passes through the horizontal strapping machine 231 and the cover plate loading machine 232 again to complete the horizontal strapping of the upper film roll group and the setting of the new top cover plate respectively.

[0101] S633, the double-layer film roll group that has completed horizontal bundling and top cover setting is vertically bundled by the vertical bundling machine 241 to ensure the structural stability of the entire double-layer film roll group.

[0102] S634, the double-layer film roll group is wrapped with film on the outer surface through the stretch film machine 242 to provide additional protection and facilitate handling. After the wrapping is completed, the double-layer film roll group is automatically affixed with the final finished product label containing product information, production date, batch number, etc. through the finished product information labeling machine 243.

[0103] S635 calls upon an AGV (Automated Guided Vehicle) to transfer the packaged double-layer film rolls from the end of the production line to a designated storage or shipping area, completing the entire packaging process. The AGV's efficient and flexible operation ensures that finished products are delivered quickly and accurately to their destination, improving overall logistics efficiency.

[0104] Example 3: Please refer to Figures 1 to 8 This embodiment provides a film roll packaging production process. The difference from embodiment 2 lies in the specific process of step S6. Steps S1 to S5 are the same as those in embodiment 2. The film roll packaging production process of this embodiment, step S6 specifically includes:

[0105] S61, using the robotic arm 211 to stack the film rolls packaged and labeled in step S5 onto the pallet of the first transplanter 212 in a preset combination until the pallet is fully loaded with the film roll group;

[0106] In this step, robotic arm 211 precisely stacks the film rolls packaged and labeled in step S5 onto the pallets of first transplanter 212 according to pre-set grouping rules, such as groups of five. This process ensures that the film rolls on each pallet are compactly and securely arranged, meeting subsequent transportation and storage requirements.

[0107] When the number of film rolls on the pallet reaches the preset full load standard, a complete single-layer film roll group is formed and is ready to enter the next stage of the packaging process.

[0108] S62, using a transfer device to transfer the stacked film roll group to the conveyor belt, and then sequentially through the horizontal strapping machine 231 and the cover plate loading machine 232 to complete the horizontal strapping of the film roll group and the installation of the top cover plate;

[0109] In this step, a fully loaded single-layer film roll is automatically transferred by a transfer device, such as the first and second transfer devices described in Example 1, to a conveyor belt in a subsequent processing area. On the conveyor belt, the roll first passes through a horizontal strapping machine 231, which uses suitable strapping materials such as plastic or steel strapping to tightly strap the roll horizontally, ensuring that the roll does not become loose or shift during transportation. The roll then moves along the conveyor belt into a cover plate loading machine 232, which automatically installs a sturdy cover plate on top of the roll to protect it from environmental damage and increase the stability of the overall structure.

[0110] S640, the film roll group that has completed horizontal bundling and top cover setting is vertically bundled by the vertical bundling machine 241. The vertical bundling machine bundles the film roll group in the vertical direction to further strengthen the structural strength of the film roll group and ensure that it will not be deformed or scattered due to external forces during transportation and storage.

[0111] S641, the film roll group that has been vertically bundled is packaged on the outer surface through the stretch film machine 242, and then the finished product information labeling machine 243 completes the final product packaging and labeling.

[0112] In this step, after vertical bundling, the film rolls enter the stretch film machine 242, where they are evenly covered with a layer of transparent stretch film. This film not only provides additional protection but also gives the rolls a neater, more professional appearance. The rolls then pass through the finished product labeling machine 243, where they are automatically labeled with key information such as product information, production date, batch number, and customer name, facilitating tracking and management.

[0113] Finally, at S642, the AGV is activated through a call system to move the finished single-layer film rolls, which have completed all packaging steps, from the end of the production line to a designated storage or shipping area. The AGV's efficient and flexible operation ensures that finished products reach their destination quickly and accurately, improving overall logistics efficiency.

[0114] Working principle of this utility model:

[0115] The utility model provides an automated film coil packaging production line, which is mainly divided into two parts: a film roll packaging preparation area and a film roll palletizing and packaging area. After the film roll completes the initial packaging in the packaging preparation area, it enters the palletizing and packaging area for subsequent palletizing and packaging processing. The palletizing mechanism uses a robotic arm and a first transplanter to achieve precise stacking of the film roll. The film roll group flows between different processes through the first, second and third conveyor belts, during which it goes through steps such as horizontal bundling, cover placement, vertical bundling, wrapping film protection and labeling, and finally completes the packaging. In addition, the production line is also equipped with a palletizing return conveying device and a second transfer device to support double-layer palletizing requirements, thereby improving the flexibility and efficiency of the production line.

[0116] The present invention also provides a film roll packaging production process with two different process flow lines. Process line one includes the steps of paper core labeling, film roll centering, hot melt sealing packaging, end cover buckling, flip labeling, palletizing and packaging. Among them, after the film roll is labeled with the paper core, it is processed by automated equipment for centering adjustment, hot melt sealing, end cover buckling and flip labeling. Subsequently, the film roll is stacked on the stacking mechanism according to a preset combination method, and horizontal bundling, cover placement, vertical bundling, wrapping film protection and final labeling are completed by conveyor belts and packaging equipment. This process line supports the reflow palletizing of the film roll group, can meet the double-layer palletizing requirements of the film roll, and improves production flexibility and efficiency.

[0117] Process line 2 is generally similar to line 1, but differs in its double-layer palletizing process. After initial packaging, the film rolls are palletized in a pre-set configuration on the palletizing mechanism in a single layer. Conveyors and packaging equipment then complete the process, including horizontal strapping, cover placement, vertical strapping, wrapping, and labeling. After single-layer palletizing and packaging, the rolls are directly delivered as finished single-layer packages without reflow palletizing. This entire process also achieves efficient, automated film roll packaging.

Any method structure that is similar to the method structure of this application, or any technical deduction or replacement based on the concept of this application, should be considered as the scope of protection of this application.
