Cable reel packaging method

Abstract

This invention discloses a method for packaging cables into a reel. The method includes: connecting multiple strip-shaped packaging pieces at predetermined intervals to form a continuous, flexible modular packaging unit; fixing the starting end of the modular packaging unit to a predetermined initial position on the periphery of the cable reel; driving the cable reel to rotate around its central axis, causing the modular packaging unit to gradually adhere to the outer surface of the reel as it rotates; and during the process of the modular packaging unit adhering and rotating with the reel, fixing each strip-shaped packaging piece within the modular packaging unit to its respective location, thereby completing the sealing and packaging of the reel's periphery. By completing the sealing, adhering, and fixing operations during the continuous rotation of the reel, the number of starts and stops and repetitive positioning during operation is reduced, which helps improve packaging efficiency and ensures the stability of the sealing quality.

Description

Technical Field

[0001] This invention relates to the field of packaging technology, and in particular to a method for packaging cable reels. Background Technology

[0002] With the continuous and rapid development of my country's power grid, communication infrastructure, and data center construction, the market demand for cables and optical fibers is increasing daily. Whether it's power grid upgrading and transformation, new energy access, or the widespread deployment of 5G networks and fiber-to-the-home, all rely on the supply of high-quality, high-efficiency cable products. During the cable production and delivery process, cable products are typically transported and stored wrapped in large wooden or composite material reels.

[0003] Most existing cable reels have an "I"-shaped structure, which generally includes reels on both sides and a shaft connecting the reels. After the cable is coiled, in order to prevent the cable from being bumped, squeezed, damp, or contaminated during loading, unloading, handling, and logistics transportation, a wooden sealing plate is usually installed around the reel to form a circumferential protection for the coiled cable, so as to ensure the performance and delivery quality of the cable product.

[0004] Traditional tray sealing and packaging mainly relies on manual operation. (See also...) Figure 1 As shown, during the specific operation, the operator moves the long strip-shaped packages one by one and aligns them at predetermined positions on the outside of the tray. Then, the two ends of the strip-shaped packages are fixed to the side plates (trays) of the tray using a pneumatic nail gun or a hand hammer. After fixing one strip-shaped package, the tray needs to be rotated around its central axis by a specific angle to rotate the next plate to be sealed to a direction that is easy to operate. Then, the steps of taking wood, positioning, nailing, and rotating are repeated until the entire circumference of the tray is closed by the strip-shaped packages.

[0005] Since the strip packaging may still loosen or even fall off if it is only secured at the end during subsequent handling or rolling of the tray, it is usually necessary to set two or more steel strapping straps around the outside of the tray for circumferential binding and reinforcement after the sealing operation is completed, so as to ensure the overall stability of the sealing structure.

[0006] The aforementioned manual sealing method has gradually revealed several problems in practical applications. Firstly, this process requires operators to frequently move the strip packages and repeatedly rotate the trays, resulting in high labor intensity, a noisy working environment with flying sawdust, and certain safety hazards. Secondly, the sealing efficiency is highly dependent on the operator's skill level, leading to worker fatigue and making it difficult to match the packaging pace with the output pace of modern high-speed cable production lines. Furthermore, since the positioning and securing of the strip packages relies heavily on manual experience, the consistency of the sealing fit and securing position is difficult to guarantee, potentially affecting the overall strength and protective effect of the sealing structure. This could lead to risks such as sealing detachment and cable damage during long-distance transportation.

[0007] To address these issues, automated or semi-automated packaging equipment has emerged in the industry to replace manual labor in sealing trays. Most existing solutions employ a design philosophy of functional replacement for manual operations, using automated components to simulate various manual actions. For example, multi-degree-of-freedom robotic arms replace manual handling of strip packages, machine vision systems or mechanical limiting devices achieve package positioning, automatic nailing machines (such as multi-axis nail guns) replace manual nailing, and motor-driven roller conveyors or friction wheel mechanisms rotate the trays at predetermined angles. The entire sealing process is programmed and coordinated by a central controller, cyclically executing steps such as "robotic arm picking up and placing strip packages—automatic nailing—drive mechanism rotating trays."

[0008] Although the above scheme has transformed the main operation from manual to equipment, its core process has not changed substantially. It still follows the basic idea of ​​manual sealing operation, that is, taking a single strip package as the object of processing, and completing operations such as taking the package in place, positioning, nailing and rotating the tray in sequence. Its essence is still a mechanized replication of the manual sealing steps.

[0009] Under the aforementioned technical solutions, regardless of whether manual operation or the existing automated mechanical replacement scheme is used, the tray sealing operation follows a sequential operation mode of "single strip processing, sequential fixing, and intermittent rotation". After each strip package is installed, the sub-processes of material picking, positioning, nailing, and rotation must be completed in sequence. The tray needs to be started and stopped multiple times during the sealing process and coordinated with rotation. A large amount of operation time is consumed in the frequent positioning, rotation, and idle processes, making it difficult to further improve the overall packaging efficiency.

[0010] Furthermore, to achieve accurate simulation of manual operations, current automation solutions typically integrate multiple functional modules, such as multi-degree-of-freedom robotic arms, end effectors, vision positioning systems, multi-axis automatic fastening units, and tray rotation drive mechanisms, resulting in relatively complex equipment structures and control systems. When tray dimensions, side panel widths, or strip packaging arrangement parameters change, the dimensions, positions, and operating parameters of the relevant mechanical structures often need to be rematched and adjusted, making equipment debugging a cumbersome process. Simultaneously, under long-term, high-intensity operation conditions, the joints, guide rails, and drive components of complex mechanical systems are prone to wear. Decreased precision may lead to placement deviations in strip packaging or unstable fastening quality, thereby affecting the reliability of the sealing operation.

[0011] In summary, current tray sealing and packaging technologies primarily focus on directly replacing manual sealing operations, failing to restructure the operational mode from the perspective of process flow organization. This often leads to problems such as complex equipment systems, limited operational efficiency, and high implementation costs, making it difficult to meet the demands of cable manufacturers for high-efficiency and high-stability tray sealing and packaging. Therefore, there is an urgent need for a new automated tray sealing and packaging method that differs from existing solutions in its principles and process organization. Summary of the Invention

[0012] Therefore, the technical problem to be solved by the present invention is to overcome the problems that the existing technology of fixing single strip packaging pieces one by one and cooperating with the intermittent rotation of the tray can easily lead to complex equipment systems, limited work efficiency and high implementation costs.

[0013] To solve the above-mentioned technical problems, the present invention provides a cable reel packaging method, comprising the following steps: Multiple strip packages are arranged side by side along the width of each individual strip package; a flexible connector is extended along the width of each strip package, and the multiple strip packages are connected sequentially through the flexible connector, thereby forming a continuous, flexible modular packaging unit. The starting end of the modular packaging unit is fixed at a predetermined initial position on the periphery of the cable reel; The cable reel is driven to rotate around its central axis, and the modular packaging unit rotates with the cable reel and gradually attaches to the outer peripheral surface of the cable reel; During the process of attaching the modular packaging unit and rotating with the reel, each strip packaging component in the modular packaging unit is nailed in place to complete the sealing and packaging of the cable reel.

[0014] In one embodiment of the present invention, the modular packaging unit is manufactured first, and then the modular packaging is used to seal the cable reel.

[0015] In one embodiment of the present invention, during the manufacturing process of the modular packaging unit, while the strip packaging pieces are connected in sequence to form the modular packaging unit, the starting end of the modular packaging unit that has been manufactured first is fixed at a predetermined initial position on the periphery of the cable reel, and the modular packaging is simultaneously implemented to seal the periphery of the cable reel.

[0016] In one embodiment of the present invention, at the front end of the station where the modular packaging unit is formed, the strip packaging pieces are arranged by a palletizing device and sequentially conveyed to the connection position; at the connection position, the flexible connector is arranged on the roller in the form of a roll and continuously unwound and released onto the multiple strip packaging pieces arranged thereon, and the flexible connector is fixed to the surface of the multiple strip packaging pieces, thereby completing the production of the modular packaging unit.

[0017] In one embodiment of the invention, during the formation of the modular packaging unit, a pressure roller is used to apply pressure to the flexible connector; and a nail gun is used to fix the flexible connector to the surface of multiple strip packages.

[0018] In one embodiment of the present invention, the flexible connector includes any one of a plastic strip, a fiber strip, and a thin metal strip.

[0019] In one embodiment of the present invention, the two ends of the first strip packaging piece at one end of the modular packaging unit are respectively nailed to the two sides of the cable reel to establish the initial positioning reference for the sealing and packaging operation.

[0020] In one embodiment of the present invention, at the start of the sealing operation, the starting end of the modular packaging unit is led out, and the starting end of the modular packaging unit is aligned with the initial position set on the periphery of the cable reel by a positioning device or a robot, and the starting end of the modular packaging unit is fixed.

[0021] In one embodiment of the present invention, after the temporary fixing of the starting end of the modular packaging unit is completed, the cable reel is driven by a driving device to rotate continuously and uniformly around its central axis; during the rotation of the cable reel, the modular packaging unit, under the rotational traction of the cable reel, conforms to the outer surface of the cable reel in the direction of the cable reel's rotation.

[0022] In one embodiment of the present invention, as the modular packaging unit rotates with the cable reel, it is pressed and adhered to the outer surface of the rotating cable reel by an auxiliary pressing member.

[0023] In one embodiment of the present invention, when manufacturing the modular packaging unit, the total length of the modular packaging unit in the unfolded state is greater than the outer perimeter of the corresponding cable reel.

[0024] In one embodiment of the present invention, after the cable reel completes one rotation and the terminal of the modular packaging unit is finally nailed to the cable reel, the excess flexible connector and modular packaging unit material are cut off to complete the outer sealing and packaging of the cable reel.

[0025] In one embodiment of the present invention, during the continuous rotation of the cable reel and the process of the modular packaging unit fitting onto its outer surface as the reel rotates, an automatic fastening device fixedly mounted on the frame fastens the modular packaging unit passing through the fastening station, so that the fastening action is completed while the reel is continuously rotating.

[0026] In one embodiment of the present invention, the fastening action of the automatic fastening device is triggered according to a preset time rhythm or a sensor signal used to detect the arrival of the strip package at the fastening station, thereby realizing the dynamic fastening of the strip package in the modular packaging unit.

[0027] In one embodiment of the present invention, an automatic fastening device is provided at both ends along the axial direction of the cable reel, and the fastening action is performed near both ends of each strip package to fix the strip package to the two sides of the reel.

[0028] The technical solution of the present invention has the following advantages compared with the prior art: This invention connects multiple strip-shaped packages to form a continuous, flexible modular packaging unit. This eliminates the need for individual handling and positioning of each package during the cable reel sealing process. Instead, as the reel rotates, the modular packaging unit gradually conforms to the outer surface of the reel, securing each package during this process. Thus, the sealing operation, which previously required frequent reel starts and stops and repeated positioning, is transformed into a continuous packaging process completed under continuous reel rotation. This reduces idle time and downtime, improving the overall continuity of the operation.

[0029] During the sealing process described above, the relative position and spacing between the strip packages are maintained by the modular sealing unit itself, eliminating the need for individual alignment and spacing adjustments for each strip package during the main line operation. During sealing, the modular sealing unit simply needs to be extended and attached to the periphery of the tray, and it can be fixed in conjunction with the tray's rotation. This reduces reliance on complex gripping mechanisms and high-precision positioning systems, simplifying the equipment structure and reducing implementation difficulty.

[0030] Meanwhile, the nailing operation is completed while the tray is rotating, so that the tray does not need to be stopped repeatedly or the nailing position needs to be readjusted during the sealing process. This reduces work interruptions, helps to ensure the uniformity of the nailing position of the strip package, and makes the packaging operation cycle more stable.

[0031] In addition, the length of the modular packaging unit and the spacing of the strip packaging can be matched and set according to the specifications of the cable reel. When the specifications of the reel change, it is only necessary to replace the modular packaging unit of the corresponding specifications and adjust the relevant process parameters to complete the sealing and packaging operation of reels of different specifications, reduce the workload of equipment structure adjustment and re-teaching, and improve the adaptability of the production line to reels of multiple specifications.

[0032] In summary, this invention achieves a transformation from intermittent to continuous cable reel sealing and packaging operations without increasing the complexity of the equipment structure. While improving packaging efficiency, it also helps maintain the stability and consistency of sealing quality, demonstrating good industrial applicability. Attached Figure Description

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0037] The cable reel 30 is used for winding, transporting and storing cables. It needs to be surrounded by a strip packaging piece 10 to form a sealing structure to protect the cables on the reel. Example 1:

[0038] See Figures 1 to 4 As shown, Embodiment 1 of the present invention discloses a method for packaging cable reels, comprising the following steps: First, multiple strip-shaped packaging components 10 are connected at predetermined intervals to form a continuous, flexible modular packaging unit 20. The modular packaging unit 20 is composed of multiple strip-shaped packaging components 10, with a relatively fixed interval between each component, allowing the modular packaging unit 20 to bend and continuously unfold along the periphery of the cable reel 30. Preferably, the strip-shaped packaging components 10 are wooden strips, but other strip-shaped components suitable for cable packaging and protection can also be used. Specifically, the modular packaging unit 20 is formed by arranging a predetermined number of strip-shaped packaging components 10 side-by-side along the width direction of each individual component; extending a flexible connector 40 along the width direction of the strip-shaped packaging components 10, and sequentially connecting the multiple strip-shaped packaging components 10 arranged side-by-side along the width direction through the flexible connector 40, thereby forming a continuous, flexible modular packaging unit 20.

[0039] Subsequently, the starting end of the modular packaging unit 20 is fixed at a predetermined initial position on the periphery of the cable reel 30, so that an initial correspondence is established between the modular packaging unit 20 and the cable reel 30 when the sealing operation begins.

[0040] After the starting end is fixed, the cable reel 30 is driven to rotate around its central axis. During the rotation of the reel, the modular packaging unit 20 rotates with the cable reel 30 and gradually attaches to the outer peripheral surface of the cable reel 30, so that the modular packaging unit 20 unfolds sequentially along the periphery of the reel and covers the outer peripheral area of ​​the reel.

[0041] During the process of attaching the modular packaging unit 20 to and rotating with the cable reel 30, each strip packaging component 10 in the modular packaging unit 20 is nailed to secure itself, so that each strip packaging component 10 is fixed to the cable reel 30 in sequence during the rotation of the cable reel 30, thereby completing the sealing and packaging of the cable reel 30.

[0042] Through the above steps, the strip package 10 can be attached and fixed during the rotation of the cable reel 30 until a continuous sealing plate structure is formed around the cable reel 30.

[0043] In this embodiment, by connecting multiple strip-shaped packaging components 10 to form a modular packaging unit 20, the sealing and packaging process of the cable reel 30 no longer requires picking up, placing, positioning, and fixing each strip-shaped packaging component 10 individually. Instead, during the rotation of the cable reel 30, the modular packaging unit 20 gradually attaches to the outer surface of the cable reel 30 as the cable reel 30 rotates, and the nailing operation of the strip-shaped packaging components 10 is completed during the attachment process.

[0044] In the traditional sealing method, each strip package 10 is set up independently, and there is no fixed relative position relationship between the strip packages. Therefore, during the sealing process, it is necessary to complete the picking, placement, alignment and positioning and nailing operations for each strip package separately. After the single strip package is fixed, the machine is stopped or rotated in coordination with the tray to enter the sealing process of the next strip package.

[0045] In this embodiment, multiple strip-shaped packages 10 are flexibly connected to form a modular packaging unit 20. The relative order and spacing between the strip-shaped packages are defined before the sealing operation, allowing the modular packaging unit 20 to unfold as a whole as the cable reel 30 rotates. During the sealing process, there is no need to repeatedly pick up and place individual strip-shaped packages and perform separate positioning operations. Instead, as the cable reel 30 rotates continuously, the modular packaging unit 20 is attached to the outer periphery of the reel segment by segment, and the fastening of each strip-shaped package is completed simultaneously. This reduces non-sealing operations such as downtime, alignment, and return caused by handling individual packages, making the sealing process more seamless and improving overall work efficiency.

[0046] Meanwhile, each strip package 10 maintains a relatively fixed spacing within the modular packaging unit 20, eliminating the need to adjust the spacing and alignment of each individual strip package 10 during the sealing process. This reduces the reliance on precise positioning of each package during sealing operations and simplifies the packaging process.

[0047] Furthermore, the fastening of the strip package 10 is completed while the tray is rotating, so that the fixing process does not require repeated stopping or repositioning of the tray, ensuring the uniformity of the distribution of the strip package 10 along the periphery of the tray and improving the stability of the sealing process.

[0048] It should be noted that in this embodiment 1, the modular packaging unit 20 is manufactured first, and then the modular packaging unit 20 is used to seal the cable reel 30. Since the modular packaging unit 20 is manufactured before the sealing operation, its overall length, the number of strip packaging pieces 10, and the spacing between adjacent strip packaging pieces 10 can all be uniformly controlled at the front-end station, which helps to improve the consistency of sealing quality and reduce the dependence on real-time adjustment and synchronous control accuracy during the sealing operation.

[0049] Therefore, this embodiment 1 separates the manufacturing process of the modular packaging unit 20 from the sealing and packaging process in stages, making the sealing process more controllable and suitable for application scenarios with high requirements for sealing consistency and process stability.

[0050] The flexible connector 40 used to connect the strip packages 10 is made of any one of plastic tape, fiber tape, or thin metal tape. The flexible connector 40 is used to connect multiple strip packages 10 to form a modular packaging unit 20, ensuring that the modular packaging unit 20 has the necessary flexibility while maintaining a stable connection as it rotates and fits with the cable reel 30. During the sealing process, after the starting end of the modular packaging unit 20 is fixed to the periphery of the cable reel 30, it gradually fits with the outer circumference of the cable reel 30 as it rotates, and secures the strip packages 10 during the rotation and fitting process.

[0051] By selecting flexible connectors 40 made of different materials, the bending performance and usage cost of the modular packaging unit 20 can be considered while meeting the connection strength requirements.

[0052] See Figure 5 As shown, each strip-shaped package 10 is provided with a connection hole. The flexible connector 40 passes through these connection holes to connect multiple strip-shaped packages 10 in series to form a modular packaging unit 20. During the sealing operation, the modular packaging unit 20 is extended as a whole and the starting end is fixed. As the cable reel 30 rotates around the central axis, the modular packaging unit 20 rotates with the cable reel 30 and attaches to the outer peripheral surface of the cable reel 30. During the attachment process, each strip-shaped package 10 is fixed with nails 50.

[0053] By providing connection holes on the strip packaging 10, a clear through-connection relationship is formed between the flexible connector 40 and the strip packaging 10, so that the connection positions of the modular packaging units 20 are consistent and a stable spacing between the strip packaging units 10 can be maintained.

[0054] See Figure 6As shown, the flexible connector 40 does not pass through the interior of the strip package 10, but extends along the surface of the strip package 10 and is fixed to the surface of each strip package 10, for example, by adhesive or fasteners, thereby connecting multiple strip packages 10 in series to form a modular packaging unit 20. During the sealing process, the modular packaging unit 20 is rotated and unfolded with the cable reel 30, and the strip packages 10 are secured during the rotation and bonding process.

[0055] The above method eliminates the need for additional connection holes on the strip packaging 10, simplifying the processing steps of the strip packaging 10.

[0056] See Figure 3 As shown, at the start of the sealing operation, the starting end of the modular packaging unit 20 is first led out, and the starting end is aligned with the initial position set on the periphery of the cable reel 30 by a positioning device or a robotic arm. Then, the starting end of the modular packaging unit 20 is temporarily fixed. After the alignment and temporary fixing of the starting end are completed, the reel is rotated, so that the modular packaging unit 20 gradually attaches to the periphery of the reel as the reel rotates, and the strip packaging 10 is nailed in place during the rotation and attachment process.

[0057] By aligning and temporarily fixing the starting end, the displacement of the modular packaging unit 20 during the initial rotation of the disk can be reduced.

[0058] After the modular packaging unit 20 is fixed at its starting end, the cable reel 30 is driven by a drive device to rotate continuously and at a constant speed around its central axis. The drive device includes a motor and a transmission assembly connected to it. The transmission assembly is coaxially connected to the central axis of the cable reel 30, transmitting the rotational torque generated by the drive device to the central axis of the cable reel 30, thereby driving the cable reel 30 to rotate around its central axis, providing stable rotational power for the reel during the sealing operation.

[0059] Under the traction of the rotating cable reel 30, the modular packaging unit 20 gradually attaches to the outer surface of the reel in the direction of rotation of the cable reel 30, and during the process of attachment and rotation with the cable reel 30, it nails each strip package 10.

[0060] By keeping the tray rotating continuously and at a constant speed under the action of the drive device, the modular packaging unit 20 is subjected to more uniform force during the bonding process, avoiding vibration or local loosening during bonding. This facilitates the coordination between the fastening operation and the tray rotation, and improves the continuity and stability of the sealing operation.

[0061] See Figure 1As shown, during the process of the modular packaging unit 20 rotating and attaching to the outer surface of the cable reel 30, an auxiliary pressing component applies pressure to the modular packaging unit 20, ensuring it adheres tightly to the outer surface of the reel. The auxiliary pressing component can be a pressure roller, pressure wheel, pressure plate, or a pressing element with elastic restoring capability located around the cable reel 30. Its position is fixed on the frame, and it contacts the outer surface of the cable reel 30 or the modular packaging unit 20 during the sealing operation, applying continuous bonding pressure to the modular packaging unit 20. While maintaining the bonding state, the wooden strip is nailed in place.

[0062] By using the auxiliary clamping component, the modular packaging unit 20 can be guided and clamped during the rotation and bonding process of the cable reel 30, reducing the lifting, springback or local loosening of the strip packaging 10 during the bonding process, improving the stability and consistency of the modular packaging unit 20 attached to the outer surface of the reel, and thus facilitating the smooth progress of the fastening operation.

[0063] When forming the modular packaging unit 20, the total length of the modular packaging unit 20 in its unfolded state is greater than the outer perimeter of the corresponding cable reel 30. During the sealing operation, the modular packaging unit 20 can cover the required sealing area around the cable reel 30 as it rotates and fits together with the cable reel 30.

[0064] By controlling the length of the modular packaging unit 20, the necessary margin can be left for terminal fixing and finishing processing when the sealing plate is almost completed.

[0065] After the modular packaging unit 20 has rotated at least one revolution with the cable reel 30 and been attached and fixed, the terminal of the modular packaging unit 20 is finally nailed in place, and excess flexible connectors 40 and modular packaging units 20 are cut off, thereby completing the sealing and packaging of the cable reel 30 (e.g., Figure 4 (As shown).

[0066] By cutting the plate after completing circumferential coverage, the end position of the sealing plate can be clearly defined, avoiding excess material from affecting the integrity of the sealing plate.

[0067] As the cable reel 30 rotates continuously and the modular packaging unit 20 rotates with the cable reel 30 and fits against its outer surface, at least one automatic fastening device 100 fixedly installed on the frame fastens the modular packaging unit 20 that has passed through the fastening station, so that the fastening operation is completed while the reel is rotating continuously.

[0068] By completing the fastening process during the rotation of the cable reel 30, the interruptions in the sealing operation can be reduced, making the entire sealing process more continuous.

[0069] As the cable reel 30 rotates continuously and the modular packaging unit 20 rotates with the cable reel 30 and adheres to its outer surface, an automatic nailing device 100 fixedly mounted on the frame nails the modular packaging unit 20 as it passes the nailing station, thus completing the nailing operation while the cable reel 30 is continuously rotating. The automatic nailing device includes a nail gun mounting bracket and an automatic nail gun mounted on the nail gun mounting bracket. The installation position of the automatic nail gun remains fixed relative to the cable reel 30. When the wooden strip reaches the corresponding nailing position as the reel rotates, the automatic nailing device completes the nailing action, fixing the wooden strip to the reel of the cable reel 30.

[0070] By completing the nailing process during the rotation of the cable reel 30, the nailing action is coordinated with the rotation process of the cable reel 30, avoiding repeated stops of the cable reel 30 or adjustments to the nailing position for a single nailing operation. This reduces pauses in the sealing operation, making the entire sealing process more coherent and improving the overall efficiency of the sealing operation.

[0071] Specifically, an automatic nailing device is set at each end along the axial direction of the cable reel 30. During the sealing process, the wooden strips are nailed at positions close to both ends, thereby fixing the wooden strips to the two sides of the cable reel 30.

[0072] By nailing the wooden strips to both ends, a reliable connection can be formed between the sealing plate structure and both sides of the cable reel 30, improving the overall stability of the sealing plate. At the same time, the automatic nailing devices set at both ends along the axial direction of the cable reel 30 can nail the wooden strips to both ends simultaneously during the sealing process, reducing the time required for nailing one end at a time and improving the overall efficiency of the nailing operation.

[0073] The automatic nailing device is triggered according to a preset time rhythm or according to the sensor signal used to detect the arrival of the wooden strip at the nailing station, so that the wooden strip is nailed as it rotates through the nailing station with the cable reel 30.

[0074] The above triggering method can coordinate the nailing action with the rotation process of the cable reel 30, reducing the occurrence of missed nails or repeated nailing. Example 2:

[0075] See Figure 7 As shown, this embodiment 2 discloses another cable reel packaging method, which has some similarities to the cable reel packaging method of embodiment 1, but also has differences. The difference from embodiment 1 is that in this embodiment 2, the modular packaging unit 20 is not formed as a whole before the sealing operation begins, but is formed continuously during the sealing operation and is carried out synchronously with the sealing and fastening process.

[0076] Specifically, during the sealing process, multiple strip packages 10 are sequentially conveyed to the connecting station and arranged side by side along the width direction of a single strip package 10; the flexible connector 40 is set on the roller 80 in the form of a roll and is continuously unwound and released along the width direction of the strip package 10. The flexible connector 40 is sequentially fixed to the surface of multiple strip packages 10 by a nail gun, so that the strip packages 10 are gradually connected during the conveying process to form the front end of the modular packaging unit 20.

[0077] While the modular packaging unit 20 is being formed, the starting end of the already formed modular packaging unit 20 is fixed at a predetermined initial position on the periphery of the cable reel 30, and the cable reel 30 is driven to rotate continuously around its central axis by a driving device.

[0078] During the rotation of the cable reel 30, the modular packaging unit 20 that has been formed gradually attaches to the outer surface of the reel as the reel rotates; during the attachment and rotation process, the strip packaging component 10 in the modular packaging unit 20 is nailed, so that the strip packaging component 10 is fixed to the two sides of the reel 30 in sequence during the rotation process.

[0079] Therefore, the formation process of the modular packaging unit 20 and the sealing and fastening process are completed in parallel in the same sealing operation process, without having to wait for the overall production of the modular packaging unit 20 before the sealing operation is carried out.

[0080] After the cable reel 30 completes one rotation, the terminal position of the modular packaging unit 20 is finally nailed, and the excess flexible connector 40 and modular packaging unit 20 are cut off to complete the outer sealing and packaging of the current cable reel 30; then, a new cable reel 30 is replaced and the above sealing operation process is repeated.

[0081] In this embodiment 2, by synchronizing the continuous formation of the modular packaging unit 20 with the sealing plate fastening, the sealing operation can be completed in the same continuous process, which is conducive to realizing a highly automated sealing operation organization method.

[0082] The formation process of the modular packaging unit 20 is carried out simultaneously with the sealing and packaging process of the cable reel 30. To achieve continuous formation of the modular packaging unit 20, a palletizer 60 is set at the front end of the station where the modular packaging unit 20 is formed, which is used to sort, arrange and transport the strip package 10 to the connection position in sequence.

[0083] The palletizer 60 outputs the strip packages 10 sequentially in a predetermined direction and order, so that when multiple strip packages 10 enter the connection position, they are arranged side by side along the width direction of a single strip package 10, and the spacing between adjacent strip packages 10 is consistent, thereby providing a stable arrangement for subsequent connection operations.

[0084] At the connection point, the flexible connector 40 is mounted on the roller 80 in roll form and is continuously unwound from the roller 80. After unwinding, the flexible connector 40 extends along the width of the strip package 10 onto the already arranged strip packages 10 and contacts the surface of each strip package 10. Subsequently, the flexible connector 40 is fixed to the surface of the strip packages 10, so that adjacent strip packages 10 are sequentially connected by the flexible connector 40, thereby continuously forming a modular packaging unit 20 at this station.

[0085] In the above manner, as the strip package 10 is conveyed, arranged and connected in sequence, it gradually forms a continuous and flexible modular packaging unit 20, which is then simultaneously led out to the sealing station for subsequent tray sealing and packaging.

[0086] To improve the connection stability between the flexible connector 40 and the strip packaging 10, a pressure roller 90 structure is also provided during the formation of the modular packaging unit 20. The pressure roller 90 is located above or below the laying path of the flexible connector 40 and is used to apply pressure to the flexible connector 40 when it is laid onto the surface of the strip packaging 10, so that the flexible connector 40 and the surface of the strip packaging 10 remain in a close fit.

[0087] After the flexible connector 40 is pressed and stably positioned by the pressure roller 90, the flexible connector 40 is fixed by a nail gun located at the connection position. The nail gun shoots nails into the strip packaging 10, so that the flexible connector 40 is firmly fixed to the surface of each strip packaging 10, thereby achieving a reliable connection between multiple strip packaging 10.

[0088] By using the combination of pressure roller 90 and nail gun for fixing, the flexible connector 40 can be stably laid and fixed during the continuous formation of the modular packaging unit 20, avoiding the flexible connector 40 from shifting or tilting during unwinding or conveying, thereby ensuring the continuity and consistency of the modular packaging unit 20 formation process.

[0089] It should be noted that this embodiment 2 does not use the method in embodiment 1 of forming a modular packaging unit 20 by setting connection holes on the strip packaging 10 and connecting the flexible connectors 40 through the connection holes in series.

[0090] In this embodiment 2, the modular packaging unit 20 is not manufactured as a whole before the sealing operation begins. Instead, it is gradually formed during the sealing operation by continuously connecting the strip package 10 through the flexible connector 40, and is carried out simultaneously with the rotating sealing and nailing process of the cable reel 30.

[0091] In this operating mode, the conveying, arranging, connecting, attaching and securing of the strip package 10 are all organized in the same continuous operation process. There is no need to set up a separate modular packaging unit prefabrication station before the sealing operation, nor is it necessary to carry out handling, storage or secondary take-out operations after the modular packaging unit is fully manufactured.

[0092] Since the formation process of the modular packaging unit 20 is carried out in parallel with the sealing and packaging process, after the strip package 10 is connected in sequence to form the modular packaging unit 20, it can directly enter the attachment and fastening process, reducing the transfer, buffering and repeated positioning operations of the modular packaging unit in the intermediate links.

[0093] Meanwhile, during the sealing process, the length of the modular packaging unit 20 can be continuously extended according to the rotation progress of the cable reel 30. When the cable reel 30 completes one rotation and completes the outer sealing, it is only necessary to finally nail and cut the terminal position of the modular packaging unit 20 to end the sealing operation of the current reel and enter the packaging process of the next cable reel 30.

[0094] Therefore, this embodiment 2 integrates the formation of the modular packaging unit 20 with the sealing and fastening process into a unified continuous operation process, making the sealing and packaging process more compact in time and space, and suitable for production line application scenarios with high requirements for automation, continuous operation capability and cycle time matching.

[0095] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
