Description

Technical Field

[0001] This invention relates to the field of suspended transportation technology, and in particular to a paper tube directional transportation device for paper tube manufacturing. Background Technology

[0002] Currently, in the paper tube manufacturing industry, especially in the process of multi-layer paper tube winding, large paper rolls need to be transported sequentially to the loading station for subsequent operations such as stacking and unwinding, glue coating, and tube forming. Existing technology typically employs a suspension conveyor mechanism for paper roll transfer. Specifically, a bridge crane or rail-mounted trolley, along with a chain and hooks, lifts the rolls or cores on both sides of the paper roll and moves them along a pre-set path to the loading rack next to the multi-layer glue rack. While this suspension method allows for the spatial displacement of heavy paper rolls, both hooking and releasing operations rely on manual labor: operators must first attach hooks one by one to the lifting points at both ends of the paper roll, and after the roll arrives at the loading rack, they must manually remove the hooks one by one and move them to the next roll to be lifted. This repeated hooking and unhooking process, coupled with the need for sequential layer positioning of the paper rolls on the loading rack, further increases the frequency of manual intervention.

[0003] However, the aforementioned suspension conveying method, which relies on manual assistance, has significant shortcomings in practical applications. On the one hand, the hooking and unhooking operations between the hook and the paper roll are time-consuming and require operators to frequently travel between the loading rack and the hoisting equipment, making it difficult to increase the paper roll loading cycle and becoming a bottleneck restricting the overall production efficiency. On the other hand, manual operation is easily affected by subjective factors. Deviated hook positions or unhooking in a timely manner may cause the paper roll to shake, shift, or even collide with surrounding equipment, affecting operational safety and the quality of the paper roll edges. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is that the existing technology uses a manual-assisted suspension hook method to transport paper rolls, which has the problems of cumbersome hook unhooking operation, low efficiency, poor safety and lack of directional and precise release capability.

[0005] The above-mentioned technical problems are solved by the following technical solution: The present invention proposes a paper tube orientation and transportation device for paper tube manufacturing, including a guide rail frame erected longitudinally; a transverse frame movably installed on the guide rail frame; a suspension seat movably installed below the transverse frame; a lifting member installed below the suspension seat, the output end of the lifting member having a first connecting part; and a hook frame hung below the first connecting part, the hook frame including a transversely extending support rod and at least two hooks slidably disposed on the support rod, each hook having a hook part for hooking a paper roll shaft, a pressing part for pressing the outer surface of the paper roll, and a linkage connecting the hook part and the pressing part, the linkage being configured to drive the pressing part to move downward when the hook part is subjected to an upward traction force.

[0006] In a preferred embodiment of the paper tube orientation transport device for paper tube manufacturing according to the present invention: the hook component includes a vertically arranged telescopic rod, the upper end of the telescopic rod is fixed relative to the bearing rod, and the lower end is provided with the hook portion; the pressing portion is sleeved on the outer periphery of the telescopic rod and can slide up and down along the telescopic rod; one end of the linkage component is connected to the hook portion, and the other end is connected to the pressing portion.

[0007] In a preferred embodiment of the paper tube directional transport device for paper tube manufacturing described in this invention: the telescopic rod is an elongated oval ring, with a screw threaded to each end of the elongated oval ring.

[0008] In a preferred embodiment of the paper tube orientation transport device for paper tube manufacturing according to the present invention: the pressing part includes a pressure plate and a second elastic member located below the pressure plate, the second elastic member being used to drive the pressing part to reset upward when the linkage is unloaded.

[0009] In a preferred embodiment of the paper tube directional transport device for paper tube manufacturing according to the present invention: the bearing rod is provided with a locking element for locking the position of the hook.

[0010] In a preferred embodiment of the paper tube orientation transport device for paper tube manufacturing according to the present invention: the transverse frame is driven by a first power source, and the suspension seat is driven by a second power source.

[0011] In a preferred embodiment of the paper tube directional transport device for paper tube manufacturing according to the present invention: at least one feeding rack is provided at the end of the transport direction of the guide rail frame, the feeding rack having a V-shaped support surface for supporting the paper roll shaft and a baffle provided on at least one side of the V-shaped support surface; the V-shaped support surface is composed of two relatively inclined slopes, and the baffle is vertically provided on the outer end face of the V-shaped support surface.

[0012] In a preferred embodiment of the paper tube directional transport device for paper tube manufacturing described in this invention: the number of hooks is two, and they are symmetrically arranged with the center of the bearing rod as a reference.

[0013] In a preferred embodiment of the paper tube orientation and transport device for paper tube manufacturing described in this invention: the linkage is a flexible pull line, and an elastic T-shaped rod is provided in the hook portion. The elastic T-shaped rod engages with a take-up drum, and the lower end of the flexible pull line is wound around the outer wall of the take-up drum.

[0014] In a preferred embodiment of the paper tube directional transport device for paper tube manufacturing according to the present invention: the hook frame further includes a flexible connector connected between the output end of the lifting component and the bearing rod, the flexible connector being two branch chains, the two branch chains being iron chains or steel wire ropes.

[0015] The beneficial effects of this invention are as follows: by incorporating a linkage in the hook assembly to connect the hook portion to the pressing portion, when the hook portion is pulled upward by the roll axis, the linkage simultaneously pulls the pressing portion downward to press the paper roll surface. This structure enables the paper roll to automatically complete hooking and pressing during the lifting process, eliminating the need for manual hooking and unhooking or separate operation of the pressing device, thus reducing operator requirements and auxiliary operation time.

[0016] Multiple hooks are slidably mounted on the support rod and fixed to it by locking devices. This structure can accommodate paper rolls of different lengths simply by adjusting the spacing of the hooks, eliminating the need to replace hook frames or special lifting tools. Adjustments during production changes are quick and the equipment is highly versatile.

[0017] The feeding rack adopts a combination structure of a V-shaped support surface and an end baffle. The roll rolls down the inclined surface to the bottom of the V-shaped support surface, while the end face of the roll fits against the baffle. This structure allows the paper roll to be positioned radially and axially synchronously during its descent, eliminating the need for manual adjustment or visual alignment. The positioning accuracy is stable, avoiding secondary adjustments. Attached Figure Description

[0020] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0022] Reference Figures 1-5 This embodiment provides a paper tube orientation and transport device for paper tube manufacturing, including a guide rail frame 1 erected longitudinally; a transverse frame 2 movably mounted on the guide rail frame 1; a suspension seat 3 movably mounted below the transverse frame 2; a lifting member 4 mounted below the suspension seat 3, the output end of the lifting member 4 having a first connecting portion 41; and a hook frame 5 suspended below the first connecting portion 41. The hook frame 5 includes a transversely extending support rod 51 and at least two hook members 53 slidably mounted on the support rod 51. Each hook member 53 has a hook portion 534 for hooking a paper roll shaft, a pressing portion 535 for pressing the outer surface of the paper roll, and a linkage member 536 connecting the hook portion 534 and the pressing portion 535. The linkage member 536 is configured to drive the pressing portion 535 to move downward when the hook portion 534 is subjected to an upward traction force.

[0023] In this embodiment, the application includes a guide rail frame 1 that is integrally erected above the production line and extends longitudinally along the paper roll conveying direction. A transverse frame 2 is installed on the guide rail frame 1 and can move longitudinally along the guide rail frame 1. A suspension seat 3 is provided below the transverse frame 1 and can move laterally along the transverse frame 2. A lifting component 4 is installed below the suspension seat 3. The lifting component 4 has an output end that can extend and retract vertically. The output end is provided with a first connecting part 41 for attaching a subsequent hook frame 5.

[0024] The hook frame 5 is suspended below the first connecting part 41. Its main components include a horizontally extending support rod 51, on which at least two hooks 53 are slidably mounted. The position of the hooks 53 can be adjusted according to the width of the paper roll. Each hook 53 consists of three parts: its lowest end is a hook part 534 for hooking the paper roll shaft; above the hook part 534 is a pressing part 535 for pressing the outer surface of the paper roll; the hook part 534 and the pressing part 535 are connected by a linkage 536. The function of the linkage 536 is that when the hook part 534 is subjected to an upward traction force, it can transmit power to the pressing part 535, driving the pressing part 535 to move downward.

[0025] In actual operation, the lifting component 4 lowers the hook frame 5 as a whole, causing the hook part 534 to move below the paper roll shaft. When the lifting component 4 raises the hook frame 5, the hook part 534 hooks onto the shaft and bears the weight of the paper roll, generating an upward traction force. At this time, the linkage component 536 pulls the pressing part 535 downward until the pressing part 535 is tightly attached to the outer surface of the paper roll, pressing the surface of the paper roll from above. Through this design, the hooking and pressing actions are automatically and synchronously completed during the lifting process, without the need for additional power or manual intervention. The coordinated cooperation of multiple hook parts 53 on the bearing rod 51 ensures that the two ends of the paper roll are evenly stressed, maintaining stability during subsequent longitudinal and transverse transportation, and preventing the paper roll from shaking or the raw material from unwinding due to the loose end.

[0026] The effects of adopting the above structure are reflected in the following aspects: First, by linking the hook portion 534 and the pressing portion 535 via the linkage 536, the automatic synchronization of the hooking and pressing actions is achieved. When the lifting component 4 lifts the hook frame 5, the hook portion 534 is forced to hook the roll, and at the same time, the linkage 536 drives the pressing portion 535 to descend and press against the outer surface of the paper roll. The entire process requires no additional power source, no manual intervention, and no need to add a separate pressing drive mechanism. This design fundamentally solves the industry problem in traditional suspended transportation where the paper roll surface is easily unwound due to inertia or vibration because it relies solely on the hook for support, significantly improving the stability and reliability of the transportation process.

[0027] Secondly, the hook 53 is slidably mounted on the support rod 51 and its position is adjustable, allowing the same set of hook frames 5 to adapt to paper rolls of different widths. This enables rapid switching between different paper tube specifications without changing tooling, significantly improving the equipment's versatility and changeover efficiency. Furthermore, the transverse frame 2 and the suspension seat 3 can move longitudinally and laterally, respectively, allowing the hook frame 5 and paper rolls suspended below to achieve two degrees of freedom of displacement in the horizontal plane. Combined with the lifting action of the lifting component 4, this achieves omnidirectional conveying of the paper rolls in three-dimensional space. Compared to traditional suspension equipment that relies on track alignment and can only convey in one direction, this structure can flexibly transport paper rolls to multiple parallel feeding racks 6 at the end of the production line, providing effective technical support for layered feeding of multi-layer glue racks.

[0028] Overall, the device integrates multiple functions such as hooking, clamping, conveying, and releasing into one unit through a simple mechanical linkage structure. The actions are smooth and logically consistent, which greatly reduces the number of manual operation steps, improves the automation level and operation cycle of the paper roll feeding process, and reduces material loss and safety risks caused by human operation deviations or loose ends.

[0029] Reference Figures 1-5 The transverse frame 2 is mounted on the guide rail frame 1, and its drive is provided by an independently set first power source 21. This first power source 21 is fixed at an appropriate position on the transverse frame 2 or the guide rail frame 1. It is usually a servo motor with a reducer, and the power is transmitted to the traveling wheel set of the transverse frame 2 through gear and rack transmission, synchronous belt transmission or chain transmission, thereby driving the transverse frame 2 to achieve precise longitudinal reciprocating movement along the guide rail frame 1. The first power source 21 is electrically connected to the production line control system and can control the traveling speed, displacement distance and start / stop position of the transverse frame 2 according to instructions.

[0030] The suspension seat 3 is installed below the transverse frame 2 and can move laterally along the transverse frame 2. The suspension seat 3 is independently driven by a second power source 31, which also uses a servo motor as its power source. The motor output shaft is connected to the suspension seat 3 through a transmission mechanism such as a lead screw, gear rack, or synchronous belt, converting the rotational motion into the transverse linear motion of the suspension seat 3. By precisely adjusting the speed and positioning of the second power source 31 through the control system, the transverse position of the suspension seat 3 on the transverse frame 2 can be adjusted, thereby coordinating with the longitudinal movement of the transverse frame 2, so that the hook frame 5 and the paper roll suspended below can reach any preset coordinate position in the horizontal plane.

[0031] The aforementioned dual-power-source independent drive design ensures that the lateral and transverse movements do not interfere with each other. It can be used in conjunction to achieve composite trajectory conveying or to perform individual movements for fine-tuning of position, providing a flexible and reliable motion foundation for the subsequent precise alignment and feeding of paper rolls.

[0032] At least one feeding rack 6 is provided at the end of the guide rail frame 1 along the transport direction. Multiple feeding racks 6 can be arranged horizontally side by side according to production needs, corresponding to different paper roll stations or glue rack layers. The main supporting part of each feeding rack 6 is a V-shaped supporting surface 61. The V-shaped supporting surface 61 is composed of two relatively inclined slopes. A V-shaped supporting surface 61 extending horizontally is formed between the two slopes. The opening of the V-shaped supporting surface 61 faces upward, and the two slopes are smooth and continuous. The included angle is reasonably set according to the diameter of the paper roll shaft to ensure that the roll shaft can roll smoothly down the slope and stop stably at the bottom of the groove. At the outer end face of the V-shaped supporting surface 61, a baffle 62 is vertically installed. The baffle 62 is perpendicular to the extension direction of the V-shaped supporting surface 61 and is used to limit the axial displacement of the end face of the paper roll shaft.

[0033] When the paper roll is moved by the conveyor to the top of the loading rack 6 and begins to descend, the roll first contacts the inclined surface of one side of the V-shaped support surface 61, slides down the inclined surface under the action of gravity, and finally rolls down to the lowest point of the V-shaped support surface 61. At the same time, the two end faces of the roll gradually approach the baffle 62 until they are in contact with the inner surface of the baffle 62. Through this process, the paper roll is automatically centered radially by the V-shaped support surface 61 and automatically positioned axially by the baffle 62. It can accurately fall into the predetermined position without manual assistance. This structure is simple and reliable, can adapt to paper rolls of different diameters, has no moving parts, and is easy to maintain.

[0034] The lifting component 4 is installed below the suspension base 3. It is an electric hoist with an output chain extending vertically downwards, allowing for vertical lifting and lowering. The lowest end of the output end is provided with a first connecting part 41, which is a hanging ring, hook, or lifting lug with a locking structure, used for detachable and flexible connection with the hook frame 5.

[0035] The overall suspension of the hook frame 5 is achieved through a flexible connector 52. The upper end of the flexible connector 52 is attached to the first connecting part 41, and the lower end is connected to the support rod 51 of the hook frame 5. The flexible connector 52 is usually made of chain, wire rope or high-strength webbing, which has sufficient tensile strength to transmit the lifting force of the lifting component 4, and allows the support rod 51 to swing freely in the horizontal plane. This allows it to automatically adapt to the position deviation of the roll when hooking the paper roll, avoiding jamming or alignment difficulties caused by rigid connection. The flexible connector 52 is arranged in two symmetrical sets. The upper ends of the two sets of flexible connectors 52 converge at the first connecting part 41, and the lower ends are respectively connected to the left and right suspension points of the support rod 51. The whole structure with the support rod 51 forms a stable triangular suspension structure. This triangular layout allows the support rod 51 to maintain horizontal stability during static suspension and dynamic transportation, preventing the paper roll from tilting or swaying during movement. At the same time, it evenly distributes the load to the flexible parts on both sides, extending the service life of the device.

[0036] The support rod 51 is a rigid rod extending horizontally, made of square tubing or shaped steel. Its overall structure is straight and possesses sufficient bending strength to support the weight of the paper roll. The surface of the support rod 51 is smooth and flat, without protruding weld points or burrs, ensuring smooth and unobstructed sliding adjustment of the hook 53. Lifting points are provided at both ends or the middle of the support rod 51 for fixed connection to the lower end of the flexible connector 52. These lifting points are typically welded lifting rings, threaded lugs, or through-holes, symmetrically distributed on the left and right sides. When the flexible connector 52 connects downwards from the first connection part 41 to the left and right lifting points of the support rod 51 in two paths, the entire hook frame 5 forms a stable triangular suspension posture. The support rod 51 remains horizontal during static suspension and dynamic operation, ensuring uniform force distribution at both ends of the paper roll without tilting or swaying. The length of the support rod 51 is determined according to the width specifications of the production line, and its lateral extension range covers the width range of common paper rolls. Combined with the sliding hook 53, it can flexibly adapt to the lifting needs of paper rolls of different widths.

[0037] At least two hooks 53 are slidably sleeved on the support rod 51. The hooks 53 are slidably engaged with the support rod 51 through the sliding sleeves 531 provided on their upper parts. The inner hole of the sliding sleeves 531 matches the outer diameter of the support rod 51, which ensures easy sliding adjustment of position while avoiding excessive shaking. Each hook 53 consists of a vertically arranged telescopic rod 533, a hook part 534 fixed to the lower end of the telescopic rod 533, a pressing part 535 sleeved on the outer periphery of the telescopic rod 533, and a linkage 536 connecting the hook part 534 and the pressing part 535.

[0038] The upper end of the telescopic rod 533 is interlocked with the sliding sleeve 531. The sliding sleeve 531 has radial holes and a locking handle. After the hook 53 is adjusted to the predetermined position, the locking handle can be operated to fix the sliding sleeve 531 and the bearing rod 51 relative to each other, preventing displacement during transportation. The telescopic rod 533 is an elongated oval ring 5331, with a screw threaded to each end of the elongated oval ring 5331. This structure, which combines the elongated oval ring 5331 with double screws, ensures that the telescopic rod 533 has sufficient axial rigidity to bear the weight of the paper roll, and also allows for flexible adaptation of the installation length through thread adjustment. At the same time, it provides a stable installation environment for the return spring. The overall structure is simple, easy to assemble, and reliable to adjust.

[0039] The hook part 534 is installed at the lowest end of the telescopic rod 533 and is J-shaped. This J-shaped hook is made of round or flat steel. The upper part of the hook body is connected to the lower end of the telescopic rod 533 by threads or welding. The lower part of the hook body is bent forward and upward to form a hook opening, with the opening direction vertically upward. The inner contour of the hook opening is arc-shaped, which matches the outer circular surface of the paper roll shaft. The depth and opening width of the hook opening are designed to stably accommodate the diameter of the roll shaft. When installing, the hook part 534 keeps the hook opening facing the direction of the paper roll shaft, that is, when the hook part 53 is aligned with the paper roll, the open side of the hook opening is directly opposite the axis of the roll shaft. The J-shaped hook structure has a self-guiding function during hooking: when the lifting component 4 raises the hook frame 5, the arc surface of the inner wall of the hook opening automatically slides along the outer arc surface of the roll, allowing it to slide smoothly under the roll without precise alignment; after the roll enters the hook opening, it naturally falls to the bottom of the hook opening under the weight of the paper roll. At this time, the upward opening shape of the hook opening forms a stable supporting fit with the roll, preventing the roll from coming off the side of the hook opening during transportation. Simultaneously, a connection point for the linkage component 536 is reserved at the root of the J-shaped hook for fixing the end of the linkage component 536. This connection point can be set as a through hole, a hook, or a welded ear plate to ensure that the linkage component 536 can instantly transmit traction force when the hook part 534 is under force. The surface of the hook part 534 can be galvanized or coated with rubber to prevent rust and avoid scratching the surface of the roll. The overall structure is simple and compact, with low manufacturing cost. Together with the telescopic rod 533, the linkage component 536, and the holding part 535, it forms a complete automatic hooking and clamping integrated unit.

[0040] The holding part 535 is plate-shaped with a central hole and is fitted onto the elongated outer periphery of the telescopic rod 533. The pressure plate 5351 of the holding part 535 can slide freely along the axial direction on the telescopic rod 533. A second elastic element 5352 is provided inside the elongated ring 5331 of the telescopic rod 533. The second elastic element 5352 is fitted onto the outside of the screw. An inner step is provided on the upper part of the holding part 535. This inner step is located on the upper end face of the second elastic element 5352. Thus, when the holding part 535 descends, it descends along the elongated ring 5331 of the telescopic rod 533 and compresses the second elastic element 5352. Conversely, when it ascends, the second elastic element 5352 pushes the holding part 535 upward.

[0041] One end of the linkage 536 is connected to the root of the hook portion 534, and the other end extends upward and connects to the upper end face or side wall of the holding portion 535. The linkage 536 is a flexible pull line 5363. An elastic T-shaped rod 5361 is provided inside the hook portion 534. The elastic T-shaped rod 5361 engages with a take-up drum 5362. The lower end of the flexible pull line 5363 is wound around the outer wall of the take-up drum 5362. The effective length of the flexible pull line 5363 is configured such that when the hook portion 534 is in a free state, the holding portion 535 is located at the upper part of the telescopic rod 533; when the hook portion 534 is subjected to an upward pulling force, the linkage 536 is tensioned and pulls the holding portion 535 to slide downward along the telescopic rod 533.

[0042] Specifically: An elastic T-shaped rod 5361 is installed inside the opening of the hook part 534. The elastic T-shaped rod 5361 is composed of a T-shaped rod and a spring sleeved on its body. The long part of the T-shaped rod is arranged in the vertical direction, and its surface is machined with a rack structure. The rack meshes with a gear coaxially arranged with the winding drum 5362. A flexible pull line 5363 is wound on the winding drum 5362, and the end of the flexible pull line 5363 is fixedly connected to the holding part 535.

[0043] When the paper roll enters the opening of the hook part 534, the outer circular surface of the roll first contacts the end of the crossbar of the T-shaped rod, and pushes the T-shaped rod to move downward against the elastic force of the spring. During the downward movement of the T-shaped rod, the rack on the long bar of the T-shaped rod drives the gear to rotate, which in turn drives the winding drum 5362 to rotate, gradually winding up the flexible pull line 5363. The shortening traction holding part 535 of the flexible pull line 5363 slides downward along the elongated ring 5331 of the telescopic rod 533, while the holding part 535 compresses the spring inside the telescopic rod 533.

[0044] The flexible pull cord 5363 is made of a composite rope with a pre-set elastic fiber or rubber core. When the holding part 535 has tightly adhered to the outer surface of the paper roll and cannot continue to descend, if the winding drum 5362 is still winding, the flexible pull cord 5363 will be moderately stretched to absorb the excess stroke, thereby preventing the holding part 535 from applying excessive pressure to the paper roll or causing the mechanism to jam due to rigid tension. This elasticity parameter is designed to ensure that the holding part 535 can contact and press against the outer wall of the paper roll throughout the entire stroke of the roll when it is fully inserted into the bottom of the hook part 534, and there will be no failure situation where the pull cord has finished winding but the holding part 535 has not yet reached its position. Through the cooperation of the aforementioned elastic T-shaped rod 5361 and the winding drum 5362, the hook part 534 supports the winding shaft while converting the displacement signal of the winding shaft into the downward pressure of the pressing part 535 in real time, realizing the mechanical synchronization of the two actions of hooking and pressing, and having automatic stroke compensation capability, further improving the adaptability and operational reliability of the device to paper rolls of different diameters.

[0045] Through the above connection, the entire hook frame 5 forms a complete force transmission path from the lifting member 4 to the hook part 534, and the upward pulling force generated by the load on the hook part 534 is synchronously converted into the downward pressure of the holding part 535 through the linkage member 536, so as to realize the mechanical linkage of hooking and pressing.

[0046] Reference Figures 1-5 The following describes the working process of this device in detail, based on the action sequence. This process is automatically executed by the PLC controller according to a preset program: (1) Initial preparation and parameter setting: According to the width of the paper roll to be transported, manually slide the two hooks 53 on the support rod 51 to adjust the distance between them to match the length of the paper roll shaft, and fix the hooks 53 and the support rod 51 relative to each other through the locking piece 532; initialize the control system, the transverse frame 2 and the suspension seat 3 return to the origin of the guide rail frame 1 entrance end, and the lifting piece 4 rises to the upper limit position.

[0047] (2) Paper roll positioning and suspension device alignment: The forklift unloads the paper roll into the waiting area at the entrance of the guide rail frame 1. The paper roll is placed horizontally with both ends of the roll suspended in the air. The controller drives the first power source 21, and the transverse frame 2 moves longitudinally to directly above the paper roll. At the same time, the second power source 31 is driven, and the suspension seat 3 moves laterally so that the hook parts 534 at the lower ends of the two hook parts 53 on the left and right are respectively aligned with the ends of the roll of the paper roll.

[0048] (3) Telescopic rod 533 contact and low position preparation: Lifting component 4 releases the chain, flexible connector 52 and the entire hook frame 5 descend rapidly; at this time, telescopic rod 533 is in the extended state under the action of internal spring, and hook part 534 is in the lowest position; when the lower end of telescopic rod 533 or the back of hook part 534 touches the paper roll shaft, lifting component 4 stops descending, at this time the height of hook part 534 is slightly lower than the lower generatrix of the roll shaft.

[0049] (4) Automatic hooking and roll locking: The lifting component 4 retracts the chain, and the hook frame 5 is lifted as a whole; the hook part 534 slides upward along the arc surface of the side of the roll, and after passing the lowest point of the roll, it automatically hooks into the bottom of the roll under the action of gravity and tension; at the moment of hooking, the roll exerts pressure on the elastic T-shaped rod 5361 inside the hook part 534, and the elastic T-shaped rod 5361 descends to drive the winding drum 5362 to rotate, and then pulls the holding part 535 down through the flexible pull line 5363 of the linkage component 536, and the holding part 535 overcomes the elastic force of the second elastic component 5352, and slides down along the telescopic rod 533 until it is tightly pressed against the top of the outer surface of the paper roll; at this time, the paper roll is supported from below by the hook part 534, and at the same time the holding part 535 presses the surface of the paper roll from above, effectively preventing the paper roll from loosening or accidentally unfolding during transportation.

[0050] (5) Lifting and directional transport: The lifting component 4 continues to retract the chain, lifting the paper roll to the set height; the controller drives the first power source 21 and the second power source 31 synchronously according to the target feeding rack 6 number, so that the transverse frame 2 moves longitudinally and the suspension seat 3 moves laterally, realizing the composite movement of the paper roll in the plane, and accurately transporting the paper roll to the top of the corresponding feeding rack 6; during the transport process, the pressing part 535 remains in a downward state to ensure that the surface of the paper roll is always in close contact with the roll body.

[0051] (6) Precise positioning and V-shaped self-alignment: When the paper roll moves to the top of the feeding rack 6, the lifting component 4 releases the chain, and the paper roll slowly descends; the paper roll shaft first contacts the inclined surface of the V-shaped support surface 61 of the feeding rack 6, and slides down the inclined surface under the action of gravity until it rolls to the bottom of the V-shaped support surface 61; at the same time, the end faces of the two ends of the shaft contact the baffle 62 on the side of the feeding rack 6 to achieve axial positioning; at this point, the paper roll completes automatic centering and positioning in both the radial and axial directions.

[0052] (7) Unhooking and Resetting: After the paper roll is placed, the weight of the roll bearing is on the feeding rack 6, and the weight of the paper roll borne by the hook part 534 disappears; the linkage 536 loosens, and the holding part 535 automatically slides upward under the action of the second elastic member 5352, detaching from the surface of the paper roll; the lifting member 4 continues to release the chain a short distance, so that the hook part 534 is completely detached from the roll; the controller drives the second power source 31, so that the two hook parts 53 drive the hook part 534 to move laterally to the outside, completely detaching from the interference of the roll; the lifting member 4 retracts the chain, raising the hook frame 5 to the upper limit position; the transverse frame 2 and the suspension seat 3 return to the entrance end of the guide rail frame 1, ready for the transportation of the next paper roll.

[0053] (8) Cyclic operation: Repeat steps (2) to (7) above to transport each paper roll to the corresponding multi-layer feeding rack 6 in sequence to achieve fully automatic cyclic operation.

[0054] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
