Description

Technical Field

[0001] This invention belongs to the field of roll packaging technology, and particularly relates to an automatic packaging equipment for roll products based on multi-station continuous conveying and its control method. Background Technology

[0002] Roll products (such as plastic film rolls, polymer material rolls, leather rolls, and electronic-grade functional film rolls) are core basic materials in industrial production and people's livelihoods, widely used in food packaging, electronic component encapsulation, building waterproofing, automotive interior processing, and many other industries. To protect the integrity of roll materials during transportation and reduce wear, they typically require packaging treatments such as outer circumferential wrapping, end finishing and sealing, and end protection to prevent surface wear, moisture absorption, end film separation, and deformation. With downstream industries increasing their requirements for the cleanliness, dimensional stability, and packaging consistency of roll materials, especially with the expanding market share of heat-sensitive, high-value-added roll materials such as lithium battery separators and optical films, roll packaging equipment not only needs high automation and cycle time capabilities but also needs to ensure high-quality end processing of the roll materials and avoid adverse effects from high-temperature processes.

[0003] Existing roll product packaging equipment mainly includes processes such as wrapping, sealing, and end cap installation, which are mostly completed by independent equipment. The equipment is usually connected by manual handling or multiple conveyor lines. The roll material needs to be transferred and repositioned multiple times between different workstations, which can easily lead to unstable cycle time, poor end packaging consistency, and increased risk of scratches on the roll material surface.

[0004] For example, Chinese invention patent with publication number CN116002392A and publication date of April 25, 2023 discloses a novel roll packaging and palletizing system. The structure includes a feeding buffer conveyor line, a feeding conveyor line, a film packaging machine, an intermediate conveyor line, a film plugging and sealing mechanism, a centering mechanism, a fully automatic case packer, an unloading conveyor line, an intermediate buffer conveyor line, a palletizing gripping conveyor line, a palletizing robot, and a palletizing pallet.

[0005] The general structural principle of the roll packaging and palletizing system in this invention patent is as follows: The roll material is placed on the material rack of the feeding buffer conveyor line, and moved to the feeding conveyor line by chain drive. Then it is moved to the film packaging machine by the feeding conveyor line. The film roller in the film packaging machine is equipped with film. The roll material moves to the conveyor belt. After one end of the film is connected to the roll material, the internal traction rotating roller drives the roll material to rotate, so that the film wraps around the outside of the roll material. After being cut by the upper and lower sealing and cutting mechanism, the roll material is pushed out to the middle conveyor line by the main pushing packaging mechanism. It enters the film plugging and end-sealing mechanism through the middle conveyor line. Through the film gathering mechanism, the hot film plugging and end-sealing mechanism and the end-sealing mechanism, the film ends are gathered, hot film is applied and end-sealing is performed respectively, so that the film ends are plugged. The material is then centered by the centering mechanism and enters the fully automatic case packer. The cardboard gripping mechanism picks up the carton, and the packing gripper grips the roll material. Simultaneously, the pre-folding mechanism expands the carton. Next, the top-page glue spraying mechanism applies glue to the top page of the carton. The main drive mechanism then folds the small and large pages sequentially. Finally, the pressing mechanism presses down the top page, completing the roll packaging. The material is then conveyed to the intermediate buffer conveyor line for buffering. Finally, it enters the palletizing gripping conveyor line, where a palletizing robot moves it onto a palletizing pallet for transport.

[0006] However, in actual use, this roll packaging and palletizing system still has at least two shortcomings, which are the technical problems that this invention aims to solve: 1. After the roll is wrapped, centering is performed, resulting in uneven residual film at both ends of the roll, which affects the quality of subsequent end sealing and the consistency of end cap fixation; 2. The end sealing process uses high-temperature methods such as hot stamping, which is not suitable for heat-sensitive rolls such as lithium battery separators and optical films, and there is a risk of heat deformation and performance damage.

[0007] Therefore, in summary, there is an urgent need for an automatic packaging equipment and control method for roll products that can ensure centering during continuous conveying and is suitable for multi-station continuous conveying of heat-sensitive roll materials. Summary of the Invention

[0008] This invention provides an automatic packaging equipment and control method for roll products based on multi-station continuous conveying. By setting up a feeding buffer mechanism, a centering mechanism, a wrapping mechanism, a feeding main drive mechanism, a discharge belt mechanism, a packing truss mechanism, a film-plugging mechanism, an adhesive tape applicator mechanism, and an end cap packaging mechanism, it achieves the following: 1. By performing the centering process and the roll wrapping process simultaneously, it avoids uneven residual film at both ends of the roll due to centering after wrapping; 2. In the end sealing process, it uses cold sealing technology instead of high-temperature hot-pressing sealing technology, eliminating the risk of heat-sensitive rolls deforming or suffering performance damage at high temperatures.

[0011] A further preferred technical solution is as follows: the film stretching assembly includes two film stretching drive units located on both sides of the film wrapping frame and horizontally arranged along the Y-axis direction; a film stretching sliding plate that is driven and moves along the Y-axis direction in conjunction with the two film stretching drive units; a plurality of L-shaped base plates spaced apart on the film stretching sliding plates and extending into the lower part of the packing film; an upper clamping plate correspondingly arranged above the L-shaped base plates; and a clamping cylinder arranged on the L-shaped base plates to drive the upper clamping plates to lift and lower to clamp one end of the packing film; the film feeding assembly includes a film feeding frame; an air shaft rotatably arranged on the film feeding frame and arranged along the X-axis direction for placing the film roll; a film feeding servo drive unit arranged on the film feeding frame for driving the air shaft to rotate; a pressure plate arranged on the film feeding frame and driven by the cylinder to clamp the other end of the packing film; and a mechanical cutter arranged on the film feeding frame and located between the pressure plate and the air shaft for cutting the packing film.

[0012] A further preferred technical solution is that the wrapping mechanism further includes an adhesive brush plate disposed on the film feeding frame for applying adhesive to the upper surface of the packaging film near the centering mechanism.

[0013] A further preferred technical solution is that the packing truss mechanism includes a packing frame, two pulley drive components horizontally arranged on the packing frame along the X-axis and close to each other, a sliding plate that is driven and moves along the X-axis in cooperation with the two pulley drive components, a linear cylinder arranged in the middle of the sliding plate and with its output end facing the wrapping mechanism, two packing guide rail pairs arranged on both sides of the linear cylinder, a packing mounting plate slidably mounted on the ends of the two packing guide rail pairs and connected to the output end of the linear cylinder, and a plurality of packing rollers rotatably arranged on the packing mounting plate and in contact with the curved surface of the roll material.

[0014] A further preferred technical solution is that the tape applicator includes an applicator frame, a film holder fixedly mounted on the applicator frame and close to the roll material, a guide wheel located downstream of the film holder, a cutter mounting plate rotatably mounted on the applicator frame and located downstream of the guide wheel, a blade block mounted on the cutter mounting plate and driven by a cylinder to extend towards the roll material, a swing cylinder mounted on the applicator frame and used to rotate the cutter mounting plate so that the blade block cuts the tape, an applicator guide rail set horizontally along the X-axis and used to slide the applicator frame, and an applicator servo drive module for driving the applicator frame to slide horizontally along the applicator guide rail set.

[0015] A further preferred technical solution is that the tape applicator further includes a roller disposed on the cutter mounting plate, located downstream of the cutter block, and driven by a cylinder to press the tape tightly onto the end of the roll material.

[0016] A further preferred technical solution is that the tape applicator further includes a brush disposed on the side end of the blade block and located upstream of the roller.

[0017] A further preferred technical solution is that the lower bearing plate and the upper clamping plate have arc-shaped surfaces that fit against the outer wall of the roll material.

[0018] A control method for an automated packaging equipment for roll products based on multi-station continuous conveying includes the following steps: S1. The roll material is placed horizontally on the feeding buffer mechanism and sent to the centering mechanism for position correction; S2. Control the pushing truss mechanism to move behind the roll and contact the outer periphery of the roll while avoiding the roll, and push the aligned roll along the conveying direction so that the roll enters the wrapping mechanism station in a rolling manner and completes the outer periphery wrapping. S3. The push-pack truss mechanism pushes the wrapped roll at a preset low speed to the front end of the feeding main drive mechanism, where it is held by the moving clamping assembly and continuously conveyed along the conveying direction. S4. During the clamping and transportation of the roll material, the film-plugging mechanism is controlled to organize and plug the packaging film at both ends of the roll material, and the tape-applying mechanism is controlled to cold-seal both ends of the roll material. S5. Control the roll material to enter the end cap packaging mechanism station in the clamping and conveying state, so as to fix the end caps at both ends of the roll material. S6. Control the roll material to be conveyed to the discharge belt mechanism to complete the unloading.

[0019] The technical effects and advantages of this invention are as follows: 1. The roll material is centered before wrapping, ensuring that the roll material is in a centered state during wrapping, effectively avoiding the problem of inconsistent end film caused by eccentric wrapping of the outer perimeter; 2. The roll material is clamped by a moving clamping component and completes multiple end processes such as film insertion, cold sealing, and end cap fixing, avoiding multiple material dropping, transfer, and repositioning in traditional processes, thus improving overall packaging efficiency and cycle stability; 3. The roll material is driven by a pushing truss mechanism to roll through the wrapping station, so that the packaging film is wrapped around the outer perimeter of the roll material under natural pressure, reducing pulling and wrinkles, and improving the flatness and reliability of the wrapping; 4. The tape application mechanism uses a cold pressing method to complete the application, avoiding heat deformation, performance degradation, or cleanliness reduction caused by hot melting or hot stamping processes on heat-sensitive roll materials, making it suitable for the packaging needs of high-value-added roll materials such as lithium battery separators and optical films.

Detailed Implementation

[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0036] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc., mentioned or possibly mentioned in this specification are defined relative to the structure shown in the accompanying drawings. The terms "inner" and "outer" refer to the direction toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0037] As attached Figure 1-13 As shown, an automatic packaging equipment for roll products based on multi-station continuous conveying includes: a feeding buffer mechanism 1, a centering mechanism 2, a wrapping mechanism 3, a feeding main drive mechanism 4, and a discharge belt mechanism 5 arranged sequentially along the conveying direction of the roll material a; a pushing truss mechanism 6 spanning above the centering mechanism 2 and the wrapping mechanism 3, used to push the roll material a at the position of the centering mechanism 2 through the wrapping mechanism 3 and into the front end of the feeding main drive mechanism 4; two film-plugging mechanisms 7 respectively arranged on both sides of the feeding main drive mechanism 4, used to organize and insert the packing film b at both ends of the roll material a; two tape-applying mechanisms 8 respectively arranged on both sides of the feeding main drive mechanism 4 and downstream of the film-plugging mechanisms 7, used to cold-seal both ends of the roll material a; and a conveying belt mechanism 5 arranged along the conveying direction of the roll material a. Two end cap packaging mechanisms 9 are located on both sides of the main material drive mechanism 4 and downstream of the adhesive tape applicator 8, for fixing the end caps to the end of the roll material a; the main material drive mechanism 4 includes a feed seat 41, a conveyor chain assembly 42 arranged on the feed seat 41 along the X-axis, and a plurality of movable clamping assemblies 43 spaced apart on the conveyor chain assembly 42 and moving synchronously with the conveying path of the roll material a; the movable clamping assembly 43 includes a lower support plate 431 for supporting the roll material a, an upper clamping plate 432 correspondingly arranged above the lower support plate 431, a clamping cylinder 433 for driving the upper clamping plate 432 to rise and fall to clamp the roll material a, and a clamping guide rail pair 434 arranged above the feed seat 41 for mounting the clamping cylinder 433.

[0038] In this embodiment, as shown in the appendix Figure 1 and attached Figure 2 As shown, the conveying path of the roll material a is from the feed end to the discharge end, and this direction is defined as the conveying direction of the roll material a, i.e., the positive X-axis direction; the transverse direction intersecting the X-axis direction is defined as the Y-axis direction, where the direction extending from left to right opposite to the positive X-axis direction is the positive Y-axis direction; the vertically upward direction is the positive Z-axis direction. Furthermore, the area near the feed end along the conveying direction is upstream, and the area near the discharge end is downstream. "Cold sealing" refers to sealing and fixing the ends by pressing with adhesive tape under normal temperature conditions, without using hot melt, hot film, or heat sealing methods, to avoid the heat-sensitive roll material being affected by heat during the sealing process. Specifically, the automatic packaging equipment for roll products based on multi-station continuous conveying includes the feed buffer mechanism 1, the centering mechanism 2, the wrapping mechanism 3, the feed main drive mechanism 4, the discharge belt mechanism 5, the packing truss mechanism 6, two film-plugging mechanisms 7, two adhesive tape-applying mechanisms 8, and two end-cap packaging mechanisms 9. The feeding buffer mechanism 1, the centering mechanism 2, the wrapping mechanism 3, the feeding main drive mechanism 4, and the discharge belt mechanism 5 are located on the conveying path of the roll material a. The pushing truss mechanism 6 is arranged across the centering mechanism 2 and the wrapping mechanism 3, used to push the roll material a, which is centered on the centering mechanism 2, onto the wrapping mechanism 3 for outer circumferential wrapping, and push the wrapped roll material a to the front end of the feeding main drive mechanism 4. The pushing truss mechanism 6 drives the roll material a to roll forward at the corresponding station. Two film-plugging mechanisms 7, two adhesive tape-applying mechanisms 8, and two end-cap packaging mechanisms 9 are arranged sequentially on both sides of the feeding main drive mechanism 4 along the positive X-axis, thereby sequentially performing film gathering and plugging, cold sealing, and end-cap fixing on both ends of the roll material a, thus obtaining the packaged roll material a.

[0039] For details, see attached. Figure 3As shown, the feeding buffer mechanism 1 includes a buffer frame 11, an inclined plate 12 disposed on the buffer frame 11 for placing the roll material a, the inclined plate 12 having grooves, a buffer guide rail 15 disposed on the buffer frame 1 and parallel to the X-axis, a buffer lifting cylinder 13 slidably mounted on the buffer guide rail 15 with its output end vertically upward, a buffer baffle 14 disposed at the output end of the buffer lifting cylinder 13 and extending out of the grooves, and an adjusting handwheel 16 for driving the buffer lifting cylinder 13 to move along the X-axis. The buffer lifting cylinder 13 is preferably a pneumatic thin cylinder or a standard cylinder to achieve rapid response; the buffer baffle 14 can be made of steel plate or high-polymer wear-resistant plate to balance strength and protection of the roll material surface. During operation, the buffer lifting cylinder 13 drives the buffer baffle 14 to extend out of the groove, and the roll material a is put in from the front end of the inclined plate 12 and blocked by the buffer baffle 14 to realize the buffer function; when it is necessary to release the roll material a into the downstream centering mechanism 2, the buffer lifting cylinder 13 drives the buffer baffle 14 to descend, and the roll material a naturally rolls to the centering mechanism 2 under the action of gravity.

[0040] For details, see attached. Figure 4As shown, the centering mechanism 2 is used to adjust the position of the roll material a in the X and Y directions to avoid uneven wrapping of the packaging film b and inconsistent end film when the roll material a enters the wrapping mechanism 3 due to eccentricity. This provides a symmetrical and consistent end allowance foundation for subsequent film plugging, adhesive application and end cap installation. The centering mechanism 2 includes a centering frame 21, a conveyor belt 22 mounted on the centering frame 21 for supporting the roll material a, a conveyor motor 23 driving the conveyor belt 22 to transport the roll material a downstream, two centering plates 24 located on both sides of the roll material a, a sliding shaft 25 mounted on the centering frame 21 and slidably mounted on the centering plates 24 via linear bearings 26, a centering drive belt 27 mounted on the centering frame 21 for driving the two centering plates 24 to move closer or further apart to laterally correct the roll material a, and a centering stop block 28 mounted on the centering frame 21 and driven by a cylinder to extend from the conveyor belt 22 to temporarily block the roll material a. The conveyor motor 23 is connected to the conveyor belt 22 for driving the conveyor belt 22 to run continuously or intermittently, thereby realizing the transport and positioning of the roll material a within the centering mechanism. The centering plates 24 are made of wear-resistant engineering plastic plates or coated plates to reduce contact friction with the roll material and avoid surface scratches. The centering drive belt 27 adopts a synchronous belt closed-loop transmission structure, including a synchronous belt body, a driving pulley and a driven pulley (located at both ends of the Y-axis stroke) set on the centering frame 21; a centering drive motor coaxially connected to the driving pulley (which can be independent of the transmission motor 23, or can share a drive source but requires force / shaft control); a tensioning pulley / tensioning mechanism (used to maintain the preload of the synchronous belt and prevent slippage and backlash); and a belt clamp / connecting block set on the synchronous belt for fixing the centering plate 24 to the synchronous belt, so that the centering plate 24 moves synchronously with the synchronous belt. During operation, the roll material a is released by the feeding buffer mechanism 1 and enters the area of ​​the conveyor belt 22. The conveyor motor 23 drives the roll material a to move downstream. At the same time, the centering drive belt 27 drives the centering plate 24 to move relative to the Y-axis, so that the centering plate 24 contacts the end face of the roll material a and applies a lateral correction force, thereby aligning the center position of the roll material a with the center line of the downstream wrapping mechanism 3, the push-pack truss mechanism 6 and the feeding main drive mechanism 4.

[0041] For details, see attached. Figure 10 and attached Figure 11As shown, the feeding main drive mechanism 4 is located downstream of the coating mechanism 3 and is used to clamp and continuously convey the coated roll material a. It includes: the feeding seat 41, the conveyor chain assembly 42, and multiple moving clamping assemblies 43. The feeding seat 41 is a mounting base used to fix the conveyor chain assembly 42 and the clamping guide rail pair 434, etc., and can be a welded steel structure or a profile frame. The conveyor chain assembly 42 is arranged on the feeding seat 41 along the X-axis direction to provide continuous driving force along the conveying direction. The conveyor chain assembly 42 can be a double-row chain, a double-speed chain, or a synchronous chain structure, and the driving method can be a servo motor or a variable frequency motor to achieve cycle matching with the coating, sealing, adhesive application, and end capping stations. The movable clamping assembly 43 is spaced apart on the conveyor chain assembly 42 and moves synchronously with the conveyor chain assembly 42. It is used to clamp the roll material a during conveying, ensuring that the roll material a maintains a stable posture after entering the feeding main drive mechanism 4 and continuously passes through the downstream end station. The movable clamping assembly 43 includes a lower support plate 431, an upper clamping plate 432, a clamping cylinder 433, and a clamping guide rail pair 434. The lower support plate 431 is located below the roll material a, supporting it and providing a lower support surface. The upper clamping plate 432 is correspondingly located above the lower support plate 431, cooperating with the lower support plate 431 to clamp the upper and lower outer circumferential surfaces of the roll material a. The clamping cylinder 433 drives the upper clamping plate 432 to rise and fall, thereby realizing the clamping / releasing action of the upper clamping plate 432. The cylinder can be a guide rod cylinder or a buffer cylinder to improve clamping stability and reduce impact. The clamping guide rail 434 is disposed above the feed seat 41 and is used to slide the mounting clamping cylinder 433. At the same time, it guides the lifting and lowering movement of the upper clamping plate 432 to ensure the verticality and repeatability of the clamping action and avoid the posture deviation of the roll a caused by skewed clamping.

[0042] Specifically, the discharge belt mechanism 5 is located at the end of the conveying path of the roll a, and is used to receive the roll a after the end sealing and end cap fixing are completed and output it to the downstream collection / palletizing / packing area. The discharge belt mechanism 5 can adopt a conventional belt conveyor structure, including a frame, drive roller, driven roller, conveyor belt and tensioning mechanism, etc.; the conveyor belt material can be selected from PVC, PU or anti-static belt surface according to the weight and surface requirements of the roll to ensure stable discharge and reduce secondary abrasion.

[0043] For details, see attached. Figure 13As shown, the two film-plugging mechanisms 7 are respectively disposed on both sides of the feeding main drive mechanism 4, and are used to organize the exposed packaging film b at both ends of the roll a and insert it inward to form an end-plugging structure, reducing end film scattering, wrinkles and curling, and providing a stable profile and reliable force foundation for downstream tape sealing and end cap fixing. The film-plugging mechanism 7 includes a film-plugging frame 71, two sets of film-gathering plates 72 disposed above the film-plugging frame 71 and disposed opposite to each other, a closing cylinder 73 disposed on the film-gathering plates 72 for driving the two sets of film-gathering plates 72 to move closer to each other to close and organize the exposed packaging film b, a film-plugging block 74 disposed on the film-plugging frame 71 and extending toward the roll a, and a film-plugging cylinder 75 for driving the film-plugging block 74 to move along the Y-axis to insert the closed packaging film b into the roll a. The film-inserting frame 71 is positioned corresponding to the end face area of ​​the roll material a. The film-gathering plate 72 is positioned at the corresponding position of the film edge at the end of the roll material a, and is used to guide and gather the exposed film edge at the end, so that the film edge tends to be concentrated and form a film bundle outline that can be inserted. The film-inserting block 74 is located at the corresponding position of the center area at the end of the roll material, and is used to press the arranged film bundle into the inner side of the end of the roll material a; the film-inserting block 74 can have a conical, hemispherical or stepped end face to adapt to different film thicknesses and insertion depths.

[0044] Specifically, the end cap packaging mechanism 9 is located in the lateral region of the feeding main drive mechanism 4 and downstream of the adhesive tape applicator 8, and is used to fix the end cap to the end of the roll material a to form a rigid end protection. The end cap packaging mechanism 9 can be a press-fit type, a snap-on / clamp type, or an adhesive-press-fit type; the end cap material can be a paper end cap, a plastic end cap, or a composite material end cap; among them, for scenarios with high cleanliness requirements or moisture resistance requirements, plastic or film-coated composite end caps are preferred.

[0045] Finally, the working principle of the automatic packaging equipment for roll products based on multi-station continuous conveying is as follows: During equipment operation, the roll material a to be packaged is first placed on the inclined plate 12 of the feeding buffer mechanism 1 by the upstream process or manually. Since the inclined plate 12 is inclined downstream, the roll material a tends to roll downstream under the action of gravity. In the initial state, the buffer lifting cylinder 13 drives the buffer baffle 14 to extend out of the groove on the inclined plate 12, blocking the roll material a, thereby temporarily stopping the roll material a in the feeding buffer mechanism 1, realizing buffering of incoming material and cycle buffering. When the equipment issues a release command, the buffer lifting cylinder 13 drives the buffer baffle 14 to descend, the buffer baffle 14 exits the groove, and the roll material a rolls naturally under the action of gravity and enters the downstream centering mechanism 2. After the roll material a enters the centering mechanism 2, the conveyor motor 23 drives the conveyor belt 22 to run, so that the roll material a moves downstream along the conveying direction or remains in a positioning state in the centering area. During the alignment process, the alignment drive belt 27 drives the two alignment plates 24 to move closer to each other along the Y-axis. Guided by the sliding shaft 25 and the linear bearing 26, the alignment plates 24 move smoothly and contact both ends of the roll a, applying a lateral correction force to the roll a to eliminate any offset in the Y-axis direction. After the roll a is aligned, the push-pack truss mechanism 6 contacts the rear outer periphery of the roll a and applies a pushing force along the conveying direction, causing the roll a to roll forward in a rolling manner. Driven by the push-pack truss mechanism 6, the roll a enters the wrapping mechanism 3 and presses onto the unfolded packing film b. As the push-pack truss mechanism 6 pushes the roll a forward, the packing film b wraps around the outer periphery of the roll a, completing the outer periphery wrapping of the roll a. Subsequently, the push-pack truss mechanism 6 continues to push the wrapped roll a, allowing it to smoothly enter the front end position of the feeding main drive mechanism 4. After the roll material a enters the feeding main drive mechanism 4, it rolls naturally onto the lower support plate 431. The clamping cylinder 433 drives the upper clamping plate 432 to move downwards and cooperate with the lower support plate 431 to clamp the upper and lower outer circumferential surfaces of the roll material a, so that the roll material a is stably clamped at the main drive station. Subsequently, the conveyor chain assembly 42 drives the roll material a to move along the conveying direction to the film-plugging mechanism 7 station. The closing cylinder 73 drives the two sets of film-gathering plates 72 to move closer to each other, guiding and gathering the exposed packaging film b at the end of the roll material a, so that the end film edges are concentrated to form a film bundle. Subsequently, the film-plugging cylinder 75 drives the film-plugging block 74 to move along the Y-axis towards the end of the roll material a, pressing the sorted film bundle into the inner side of the end of the roll material a, thereby forming a stable end inner plug structure at both ends of the roll material a.After the sealing process is completed, the roll material a continues to be conveyed downstream in a clamped state and enters the tape-applying mechanism 8. The tape-applying mechanism 8 guides the tape to the end of the roll material a at room temperature and fixes the tape to the end film layer by pressing, thus completing the cold sealing of both ends of the roll material a. After the cold sealing of the ends is completed, the roll material a continues to enter the end cap packaging mechanism 9 along the conveying direction. The end cap packaging mechanism 9 positions the end caps and fixes them to the end of the roll material a by pressing, snapping, or applying adhesive, forming a rigid protective structure at the end of the roll material a, thereby improving the end protection performance of the roll material during handling, storage, and transportation. After the end caps are fixed, the roll material a finally enters the discharge belt mechanism 5, which receives and conveys it to the downstream collection, boxing, or palletizing area, thus completing the entire automatic packaging process of the roll material a.

[0046] The beneficial effects of the automated packaging equipment for roll products based on multi-station continuous conveying are as follows: First, the roll material a is clamped by the moving clamping component 43 and completes multiple end processes such as film insertion, cold sealing, and end cap fixing, avoiding multiple material dropping, transfer, and repetitive positioning in traditional processes, thus improving overall packaging efficiency and cycle stability. Second, the roll material a is centered before film wrapping, ensuring that the roll material a is in a centered state during film wrapping, effectively avoiding the problem of inconsistent end film caused by eccentric outer wrapping, and providing a symmetrical and stable end foundation for subsequent film insertion and sealing processes. Furthermore, the push-pack truss mechanism 6 drives the roll material a to roll through the film wrapping station, allowing the packaging film b to wrap around the outer periphery of the roll material under natural pressure, reducing pulling and wrinkles, and improving the flatness and reliability of the wrapping. Finally, the tape application mechanism 8 is used to complete the application by cold pressing of the tape, avoiding heat deformation, performance degradation or cleanliness reduction caused by hot melting or hot film processes on heat-sensitive roll materials. This method is suitable for packaging high-value-added roll materials such as lithium battery separators and optical films.

The film feeding assembly 33 is configured to supply the packaged film b to the film pulling assembly 32. The film feeding assembly 33 first unwinds the packaged film b and conveys it to the end near the film pulling assembly 32; then, the film pulling assembly 32 clamps the packaged film b and unfolds it along the Y-axis, so that the packaged film b forms a stable unfolded state at the wrapping station. After the required length of packaged film b for one wrapping cycle is supplied, the film pulling assembly 32 cuts the packaged film b to proceed with the next wrapping cycle.

The film-stretching sliding plate 322 is transversely disposed between the two film-stretching drive units 321 and is driven by the film-stretching drive unit 321 through a guide rail slider or synchronous belt transmission structure, thereby enabling it to move smoothly on the film-coating frame 31 along the Y-axis direction. A plurality of L-shaped base plates 323 are arranged at intervals along the length direction of the film-stretching sliding plate 322, including vertical plates and horizontal plates. The vertical plates are fixedly connected to the film-stretching sliding plate 322, and the horizontal plates extend below the packing film b to form a support surface for the film web.

The mechanical cutter 335 is positioned between the pressure plate 334 and the air shaft 332, preferably a linear drive gate or pneumatic cutter structure, and is used to cut the packaged film b after a single wrapping and film feeding, thereby achieving continuous cyclic film feeding. Preferably, the wrapping mechanism 3 also includes an adhesive brush 34 mounted on the film feeding frame 331 for applying adhesive to the upper surface of the packaged film b near the centering mechanism 2. The adhesive brush 34 is used to apply adhesive to the upper surface of the packing film b near the centering mechanism 2. It includes an adhesive storage cavity, an adhesive outlet, and a scraping or brushing part that contacts the surface of the packing film b. The adhesive storage cavity is used to store the adhesive liquid, and the adhesive outlet is used to uniformly export the adhesive liquid to the scraping or brushing part. While the packing film b is unfolded by the film pulling assembly 32, the adhesive brush 34 forms a thin adhesive layer on one side, so that the packing film b can be stably wound on the roll material a.

The pulley drive assembly 62 and the linear cylinder 64 cooperate to drive the pusher roller 67 to move behind the roll a, and drive the roll a to roll in the conveying direction.

[0054] In this embodiment, as shown in the appendix Figure 12As shown, the adhesive applicator 81 is movably mounted along the X-axis, and its bottom is slidably mounted on the equipment frame via the adhesive applicator guide rail pair 87. The adhesive applicator guide rail pair 87 is preferably a linear rolling guide rail pair to constrain the movement direction of the adhesive applicator 81 and ensure its straightness. The adhesive applicator servo drive module 88 is fixedly mounted on the equipment frame and is connected to the adhesive applicator 81 via a transmission connection. It preferably employs a servo motor in conjunction with a synchronous belt slide or lead screw module structure to drive the adhesive applicator 81 to move linearly towards or away from the roll material a along the X-axis, thereby achieving the forward and backward positioning of the adhesive applicator station. The tape holder 82 is fixedly mounted on the adhesive applicator 81 and arranged in the direction towards the roll material a. It is used to mount the tape roll and provide support and positioning for the tape roll. The tape holder 82 is preferably configured as a detachable tension shaft or rotating shaft support structure to facilitate quick replacement of the tape roll. The guide wheel 83 is rotatably mounted on the adhesive applicator 81 and located downstream of the film roll holder 82.

[0055] The tape applicator 8 also includes a roller 89 disposed on the cutter mounting plate 84, located downstream of the cutter block 85, and driven by a cylinder to press the tape against the end of the roll material a.

[0056] In this embodiment, the roller 89 is rotatably mounted on the cutter mounting plate 84 and located downstream of the cutter block 85. The roller 89 is driven by an independent cylinder to move in the direction toward the end of the roll material a, and is used to press the tape tightly against the outer wall of the end of the roll material a, so that the tape and the roll material a form a reliable fit. The roller 89 is preferably a rubber wheel or a polyurethane coated wheel structure, so as to avoid damaging the surface of the roll material a while ensuring friction.

[0057] The tape applicator 8 also includes a brush 810 disposed on the side of the blade block 85 and located upstream of the roller 89.

[0058] In this embodiment, the brush 810 is disposed on the side end of the blade block 85 and located upstream of the roller 89. The brush 810 is preferably made of wear-resistant nylon bristles or anti-static bristles.

[0059] The lower support plate 431 and the upper clamping plate 432 have arc-shaped surfaces that fit against the outer wall of the roll material a.

[0060] In this embodiment, the arc-shaped surfaces of the lower support plate 431 and the upper clamping plate 432 are arranged along an arc shape and are adapted to the outer wall shape of the roll material a to ensure the stability of the roll material a during the clamping process. Their surfaces can be provided with arc-shaped support surfaces or wear-resistant pads to adapt to different roll diameters and reduce indentation. Preferably, the surfaces of the lower support plate 431 and the upper clamping plate 432 can be provided with an adhesive layer or replaceable pads to balance clamping friction and surface protection without damaging the surface of the roll material.

[0061] A control method for an automated packaging equipment for roll products based on multi-station continuous conveying includes the following steps: S1. The roll material a is placed horizontally on the feeding buffer mechanism 1 and sent to the centering mechanism 2 for position correction; S2. Control the pushing truss mechanism 6 to move behind the roll a while avoiding the roll a and contact the outer periphery of the roll a, and push the aligned roll a along the conveying direction so that the roll a enters the working position of the wrapping mechanism 3 in a rolling manner and completes the outer periphery wrapping. S3. The push-pack truss mechanism 6 pushes the wrapped roll a at a preset low speed to the front end of the feeding main drive mechanism 4, and is held by the moving clamping component 43 and continuously conveyed along the conveying direction. S4. During the clamping and transportation process of the roll material a, the film-plugging mechanism 7 is controlled to sort and plug the packaging film at both ends of the roll material a, and the tape-applying mechanism 8 is controlled to cold-seal both ends of the roll material a. S5. Control the roll material a to enter the end cap packaging mechanism 9 station in the clamping and conveying state, so as to fix the end caps at both ends of the roll material a. S6. Control the roll material a to be conveyed to the discharge belt mechanism 5 to complete the unloading.

[0062] In this embodiment, the control method is executed by a PLC or industrial controller and electrically connected to a servo driver, pneumatic control valve group, and detection sensors (not marked in the figure). The feeding buffer mechanism 1, the centering mechanism 2, the packing truss mechanism 6, the feeding main drive mechanism 4, the film-plugging mechanism 7, the tape-applying mechanism 8, and the end-cap packaging mechanism 9 are sequentially and collaboratively controlled. In step S1, a photoelectric sensor or proximity switch installed on the feeding buffer mechanism 1 detects the arrival signal of the roll material a, and triggers the centering mechanism 2 upon arrival. The centering mechanism 2 preferably employs a double-sided centering baffle combined with a cylinder drive, and a limit switch provides feedback of the centering completion signal as the starting condition for step S2. In step S2, the approaching and pushing actions of the pusher truss mechanism 6 are controlled in stages. First, the pulley drive assembly 62 is controlled to move the sliding plate 63 to a preset position behind the roll material a, and the position is confirmed by a position encoder or servo position feedback. Then, the linear cylinder 64 is controlled to drive the pusher mounting plate 66 to extend towards the roll material a, so that the pusher roller 67 forms rolling contact with the outer periphery of the roll material a. Then, the pulley drive assembly 62 drives the roll material a to roll into the wrapping mechanism 3 along the conveying direction at a preset pushing speed. The pushing speed is preferably controlled by segmented speed, with a low speed when the roll material a enters the entrance of the wrapping mechanism 3 to avoid impact and ensure wrapping alignment. In step S3, after the wrapping mechanism 3 outputs a wrapping completion signal, it controls the pushing truss mechanism 6 to push the roll material a to the clamping entrance area of ​​the feeding main drive mechanism 4 at a preset low speed. The moving clamping component 43 performs a clamping action after detecting that the roll material a has entered the clamping range, and confirms the clamping completion via a clamping cylinder pressure switch or displacement sensor, then controls the feeding main drive mechanism 4 to enter continuous conveying mode. The continuous conveying is preferably driven by a servo motor to achieve constant speed operation and synchronization with the subsequent workstation cycle. In step S4, the actions of the film-plugging mechanism 7 and the adhesive tape-applying mechanism 8 are performed in a follow-up coordinated manner. While the roll material a is held and conveyed, the end position of the roll material a is obtained through a workstation detection sensor, and timing compensation control is performed according to the conveying speed of the feeding main drive mechanism 4. The film-plugging mechanism 7 and the adhesive tape-applying mechanism 8 gather and plug the excess packaging film b at both ends of the roll material a. In step S5, after receiving the signal indicating that the roll a has arrived, the end cap packaging mechanism 9 performs end cap positioning, pressing, or locking actions. After the end cap fixing action is completed, a completion signal is output, which serves as the delivery release condition for step S6. In step S6, the moving clamping assembly 43 is controlled to release the roll a, and the roll a is controlled to be transitioned from the feeding main drive mechanism 4 to the discharge belt mechanism 5. The discharge belt mechanism 5 preferably adopts a constant speed motor drive to achieve stable feeding.
