Technical Field

[0001] This invention relates to the field of thin film processing technology, and in particular to a film roll transfer device. Background Technology

[0002] On automated film production lines, after the film roll completes the winding process, it needs to be unloaded. However, after winding, the film roll and the air shaft are still connected. Operators need to use venting pins to vent the air shaft, and then use a robotic gripper to grasp one end of the air shaft and pull it off the film roll, thus completing the unloading process.

[0014] Beneficial effects: This invention provides a membrane roll transfer device that integrates the membrane roll unloading function with the air shaft handling function, achieving efficient collaborative transfer of the membrane roll and the air shaft. Through the cooperation of the transfer vehicle, lifting assembly, and receiving platform, the membrane roll is consistently supported by the large-plane receiving platform during the transfer process. Compared to the traditional suspended gripping method of a robotic arm, the membrane roll's center of gravity is lowered, and the support surface is expanded, enhancing its resistance to swaying and overturning during transfer and optimizing transportation stability. Simultaneously, the receiving platform, through a hinged design, is linked with the top support assembly, enabling automatic rolling unloading of the membrane roll using gravity. The unloading process is structurally simple, reliable, and reduces the risk of damage to the membrane roll surface.

[0015] Regarding the handling of the air shaft, the device utilizes a clamping groove formed between the support frame and the clamping unit, along with the clamping drive unit, to actively clamp and position the end of the air shaft. This method results in a more rational clamping contact surface, improving the stability of the air shaft during fixation and reducing the possibility of rotation or dislodgement. The depressurization assembly is integrated into the support frame, enabling centralized control of the depressurization operation without the need for additional tools, thus simplifying the operation process. The flip-plate assembly provides auxiliary support to the other end of the air shaft, forming a stable support system together with the clamping point. This enhances the anti-tipping ability of the air shaft during temporary placement, facilitates subsequent paper core replacement and inflation operations, and improves operational safety.

[0016] Furthermore, the device achieves seamless operation from receiving to unloading of film rolls through a track frame, rotating frame, and robotic arm. The robotic arm receives the film rolls at a fixed station, improving positional accuracy, reducing deviations and impacts during the docking process, and enhancing the efficiency and continuity of the production line.

To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0021] On automated film production lines, after the film roll completes the winding process, it needs to be unloaded. However, after the winding process, the film roll and the air shaft are still connected. Operators need to use venting pins 52 to vent the air shaft, and then use a mechanical gripper to grasp one end of the air shaft and pull it off the film roll, thus completing the unloading process. This temporary fixation method for the air shaft is prone to instability in the mechanical gripper, causing the air shaft to tilt, posing a safety risk, and the entire unloading process is cumbersome. In view of the shortcomings of the prior art, the purpose of this invention is to provide a film roll transfer device to improve the stability of the air shaft fixation during film roll unloading, reduce safety risks, and simplify the operation process.

[0022] The membrane roll transfer device of this application will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 6This invention provides a film roll transfer device, including a track frame 100, a transfer cart 200 that can slide along its length on the track frame 100, a lifting assembly 300 on the transfer cart 200, a receiving platform 400 on the lifting assembly 300, one side of the receiving platform 400 being hinged to the lifting assembly 300, and a support assembly 500 on the transfer cart 200 for supporting the other side of the receiving platform 400. A support frame 8 is provided at one end of the track frame 100, and a clamping part 3 is rotatably connected to the support frame 8. A clamping groove for clamping the end of an air expansion shaft is formed between the clamping part 3 and the support frame 8. A clamping drive part 4 is provided on the support frame 8, and the output end of the clamping drive part 4 is drively connected to the clamping part 3. The clamping drive part 4 is used to drive the clamping part 3 to rotate to adjust the opening and closing state of the clamping groove. A venting assembly 5 for depressurizing the air expansion shaft is provided on the support frame 8 in the coaxial direction of the clamping groove. A flip-plate assembly 6 and a flip-plate drive unit 7 are provided at the bottom of one end of the track frame 100 near the support frame 8. The flip-plate drive unit 7 is connected to the flip-plate assembly 6 and is used to drive the flip-plate assembly 6 to swing up and down in the direction of the air shaft. A rotating frame 600 is provided on the side of the track frame 100 near the top support assembly 500. Robotic arms 700 are provided at both ends of the rotating frame 600. The rotating frame 600 is used to drive the two robotic arms 700 to move closer to or away from the receiving table 400. The air shaft end is actively clamped by the openable clamping parts 3 and the support frame 8, which expands the clamping contact surface and reduces the risk of the air shaft rotating or coming out during the fixing process. By adding a swingable flap assembly 6, auxiliary support is provided to the other end of the air shaft. This support, together with the clamping point at the end of the frame 1, forms a support system, improving the anti-tipping performance of the air shaft when temporarily placed. Simultaneously, when the transfer cart 200 approaches below the film roll, the flap assembly 6 is reset by the flap drive unit 7 to avoid collisions with the transfer cart 200. The film roll is horizontally conveyed via a large-plane receiving platform 400. Compared to suspended clamping transport, its center of gravity is lower and the support surface is larger, enhancing its anti-swaying and anti-tipping capabilities during transfer. Integrating the depressurization assembly 5 onto the support frame 8 achieves integrated depressurization operation, simplifying the operation process and improving the continuity of the production line. The tilt angle of the receiving platform 400 is adjusted by the top support assembly 500, allowing the film roll to automatically roll down using gravity. This unloading method has a relatively simple structure, and the film roll rolls down smoothly, reducing the possibility of damage to its surface.

[0024] The specific working principle is as follows: After the film roll is wound up on the production line, the rotating frame 600, located on one side of the track frame 100, drives the robotic arms 700 at both ends to move to the vicinity of the receiving platform 400 to receive the wound film roll from the winding equipment. At this time, the transfer carriage 200, driven by the sliding motor assembly 203, moves along the length of the track frame 100, precisely positioning the receiving platform 400 directly below the film roll. Subsequently, the lifting assembly 300 is activated, pushing the receiving platform 400 to rise smoothly and vertically until the surface of the receiving platform 400 contacts and supports the bottom of the film roll. The robotic arms 700 then release, and the film roll is completely transferred onto the receiving platform 400.

[0025] While the membrane roll is being transferred, the device performs another set of operations on the air shaft that holds the membrane roll in place. Before the air shaft is pulled out of the membrane roll, its end is placed on the support 8, and the clamp drive 4 starts working, closing the clamping groove between the clamp part 3 and the support 8, thus actively clamping the end of the air shaft. Then, the venting assembly 5 on the support 8 immediately actuates, moving along the axial direction of the air shaft and inserting into the air shaft's vent valve, completing the pressure relief operation on the air shaft, causing its taut key to contract, making it easier to pull out of the membrane roll.

[0026] Once the air shaft has depressurized, it separates from the film roll. At this point, the transfer trolley 200 moves the film roll, thus completing the separation of the film roll from the air shaft and transporting the film roll to the target unloading point. The top support assembly 500 then actuates, applying an upward lifting force to the bottom side of the receiving platform 400 away from its hinge axis, raising that side of the receiving platform 400. The plane of the receiving platform 400 thus tilts around its hinge axis, forming an inclined plane. Under its own weight, the film roll rolls along the inclined surface of the receiving platform 400 to the lower side, smoothly detaching from the receiving platform 400 and rolling down to the predetermined unloading point, completing the unloading operation.

[0027] Meanwhile, to provide auxiliary support for the other end of the air shaft, the flip-plate assembly 6, located at the bottom of the track frame 100 near the support frame 8, begins to operate. The flip-plate drive unit 7 drives the flip-plate assembly 6 to rotate upwards, supporting the middle of the air shaft or the other end away from the clamping part 3 from below, thus forming at least two points of stable support with the clamping part 3 and the support frame 8 on the frame 1. At this point, the air shaft is stably supported on the film support device, keeping it in a horizontal position, making it easy for workers to re-attach a new paper core to the air shaft and re-inflate it. At this time, the two robotic arms 700, driven by the rotating frame 600, re-grab the air shaft and return to the winding equipment to await the next winding process.

[0028] In actual use, the flap assembly 6 and the flap drive unit 7 are buried underground to avoid the track frame 100 in space.

[0029] Furthermore, in this embodiment, the transfer vehicle 200 includes a vehicle body 201, which constitutes the main load-bearing frame. Multiple sets of pulley groups 202 are slidably connected to the track frame 100 at the bottom of the vehicle body 201. The pulley groups 202 cooperate with the track of the track frame 100, allowing the vehicle body 201 to move smoothly along the track. To ensure stable movement, a sliding motor assembly 203 is provided on the vehicle body 201. The sliding motor assembly 203 is drivenly connected to at least one set of pulley groups 202 to provide sliding force. A lifting assembly 300 and a top support assembly 500 are respectively mounted on the vehicle body 201 and move together with the vehicle body 201. The cooperation of multiple sets of pulley groups 202 with the track forms a stable sliding pair, providing effective guidance and support for the vehicle body 201 and preventing the vehicle body 201 from shifting or overturning during transportation.

[0030] In one embodiment, the pulley block 202 is provided with a coupling shaft, and the sliding motor assembly 203 includes a motor part, which is connected to the coupling shaft via a sprocket assembly.

[0031] Furthermore, such as Figures 1 to 3 As shown, the lifting assembly 300 comprises a scissor lift platform 301 and a lifting frame 302. The scissor lift platform 301 is a common lifting mechanism, with one end of its bottom hinged to the transfer cart 200 and the other end slidably connected to the transfer cart 200. This slidable connection is achieved through the cooperation of a slider and a slide rail, allowing this end of the scissor structure to slide relative to the cart body 201 during extension and retraction. One end of the top of the scissor lift platform 301 is hinged to one end of the lifting frame 302, and the other end is slidably connected to the other end of the lifting frame 302, thereby converting the extension and retraction motion of the scissor into the vertical lifting motion of the lifting frame 302. At least one hinge seat 303 is provided on the side of the lifting frame 302 away from the top support assembly 500, and a rotating frame 401 hinged to the hinge seat 303 is provided on the corresponding side of the receiving platform 400. Through this hinge, the receiving platform 400 can rotate relative to the lifting frame 302. The scissor lift platform 301 provides a large lifting stroke while maintaining high structural rigidity and stability, possessing strong load-bearing capacity, making it particularly suitable for lifting heavy membrane rolls. The sliding connections at the bottom and top work together to ensure that the lifting frame 302 primarily moves vertically during lifting, with minimal offset and precise trajectory. This facilitates accurate and stable contact and docking between the receiving platform 400 and the bottom of the membrane roll above, reducing the risk of collisions or scratches due to positional deviations. By designing the receiving platform 400 and the lifting frame 302 as a hinged connection, two movement postures can be separated: vertical lifting and planar tilting. The lifting frame 302 provides stable and reliable vertical lifting, while the tilting of the receiving platform 400 is driven by an independent top support assembly 500 around this hinge axis.

[0032] In this embodiment, the middle part of the track frame 100 has a hollow structure, which allows for avoidance of the flip plate assembly 6 and the flip plate drive unit 7 during implementation.

[0033] It should be noted that the scissor lift platform 301 is the existing scissor lift platform 301 structure, and the specific structure and working principle are existing technologies, which will not be described in detail here.

[0034] The working process is mainly divided into two stages: the rising and receiving process and the falling and resetting process, as follows: After the transfer cart 200 moves to the receiving position below the film roll, the power source (such as a hydraulic cylinder or motor) that drives the extension of the scissor lift platform 301 is activated, causing the sliding end at the bottom of the scissor mechanism to move away from the hinge end along the slide rail on the transfer cart 200. This horizontal displacement causes the staggered hinged multi-stage scissor arms to unfold, thereby enabling the entire scissor lift platform 301 to be lifted vertically. Since one end of the top of the scissor lift platform 301 is hinged to the lifting frame 302, and the other end is slidably connected to the lifting frame 302, the lifting force is evenly transmitted to the lifting frame 302, driving the lifting frame 302 and the hinge seat 303 and the rotating frame 401 fixed thereon, thus driving the entire receiving platform 400 to rise smoothly and vertically together. The receiving platform 400 rises to contact the bottom of the film roll held by the robot arm 700 and bears its weight, completing the receiving operation.

[0035] After the film roll is transferred to the unloading point and tilted off by the top support assembly 500, the lifting assembly 300 performs a descent and reset action. The power source performs a reverse operation, pulling the sliding end of the bottom of the scissor lift platform 301 along the slide rail to retract, forcing the scissor arms to retract, driving the lifting frame 302 and the receiving platform 400 to descend vertically until they return to the transport state or the low initial state waiting for the next operation.

[0036] In one embodiment, to provide auxiliary support and mitigate impact when the receiving platform 400 is horizontal, the top of the lifting frame 302 is provided with a plurality of elastic support members 304 along its length. The elastic support members 304 may be, for example, spring plungers or spring-loaded push rods. A top plate is provided at the bottom of the receiving platform 400 corresponding to the positions of each elastic support member 304. When the receiving platform 400 is in a horizontal position, the top plate at its bottom contacts the elastic support members 304 below, compressing the elastic support members 304 and thus providing a certain elastic support force to absorb some vibration.

[0037] Furthermore, such as Figures 1 to 3As shown, the top support assembly 500 includes a top support cylinder 501, the fixed end of which is mounted on the transfer cart 200. A roller assembly 502 is disposed at the end of the piston rod of the top support cylinder 501, and the roller assembly 502 can be composed of a bracket and rotatable rollers. The roller assembly 502 abuts against the bottom of the receiving platform 400. In one embodiment, to ensure that the rollers of the roller assembly 502 can smoothly slide into the bottom of the receiving platform 400 and perform a guiding function, a guide ramp 402 is provided on the receiving platform 400 corresponding to the position of the roller assembly 502, and the guide ramp 402 has an inclined surface. When the piston rod of the top support cylinder 501 extends, the rollers can roll along the inclined surface, thereby smoothly lifting that side of the receiving platform 400. In another embodiment, to provide a cushioning effect when the lifting frame 302 descends to the bottom, the lifting assembly 300 also includes at least one cushioning support 305. The bottom of the cushioning support 305 is located on the transfer cart 200, and its output end is located below the lifting frame 302. The cushioning support 305 can be a hydraulic damper or a gas spring, etc. When the lifting frame 302 descends to near its lowest position, it contacts the output end of the cushioning support 305, and the cushioning support 305 is compressed, thereby dissipating energy and reducing impact.

[0038] During operation, the top support assembly 500, during the unloading phase, drives one side of the receiving platform 400 to rise, tilting it so that the film roll automatically rolls off under gravity. Once the transfer trolley 200, carrying the film roll from the receiving platform 400, reaches the designated unloading point and stops, the top support cylinder 501 is activated. The piston rod of the top support cylinder 501 extends outward, pushing the roller assembly 502 at its end towards the bottom of the receiving platform 400. The rollers in the roller assembly 502 first contact the inclined surface of the guide ramp 402 fixed to the bottom of the receiving platform 400. As the piston rod continues to extend, the rollers roll upward along the inclined surface of the guide ramp 402. This rolling process along the inclined surface converts the horizontal thrust of the piston rod of the top support cylinder 501 into a vertical component and a horizontal component of the force applied to the bottom of the receiving platform 400. The vertical force overcomes part of the weight of the receiving platform 400 and the film roll, gradually lifting the side of the receiving platform 400 away from the hinge axis; the horizontal force is released through the rolling of the rollers, thereby reducing sliding friction. As this side of the receiving platform 400 continues to be lifted, the entire plane of the receiving platform 400 rotates around its hinge axis with the lifting frame 302, forming an inclined surface facing the predetermined unloading direction. The film roll placed on it begins to roll smoothly down the inclined platform under the action of the gravity component along the inclined surface until it completely detaches from the receiving platform 400 and reaches the designated unloading position, completing the unloading. Subsequently, the piston rod of the support cylinder 501 retracts, the rollers roll away in the opposite direction along the guide inclined plate 402, and the receiving platform 400 returns to a horizontal state under its own weight or the action of the auxiliary reset device.

[0039] After the receiving platform 400 completes unloading and returns to a horizontal state, the lifting assembly 300 drives the lifting frame 302 and the receiving platform 400 to descend for a reset operation. To ensure the smoothness of the descent, when the lifting frame 302 descends to near its lowest position, it will contact the output end of the buffer support 305 located on the transfer vehicle 200. At this time, the buffer support 305 is compressed, and its internal damping structure converts the kinetic energy of the lifting frame 302 and the receiving platform 400 into heat energy and dissipates it, thereby quickly consuming the impact energy at the end of the descent, allowing the lifting frame 302 to smoothly and without impact stop at its final low position.

[0040] Furthermore, such as Figures 1 to 3 As shown, the rotating frame 600 includes a rotating shaft 601 extending along the length of the track frame 100. Rotating seats 602 are respectively disposed at both ends of the rotating shaft 601, and the two rotating seats 602 are rotatably connected to the two ends of the rotating shaft 601, thereby enabling the rotating shaft 601 to rotate relative to the rotating seats 602. Two robotic arms 700 are symmetrically distributed at both ends of the rotating shaft 601. A push-pull cylinder 603 is disposed on one side of each robotic arm 700, and the piston rod of the push-pull cylinder 603 is hinged to the robotic arm 700. When the piston rod of the push-pull cylinder 603 extends or retracts, it can push or pull the robotic arm 700, causing it to rotate around the hinge point on the rotating shaft 601, thereby achieving the swinging of the output end of the robotic arm 700 to move closer to or further away from the receiving table 400. In one implementation case, in order to limit the rotation range of the robot arm 700, a limit frame 604 is provided on the side of the rotating base 602 near the receiving platform 400. The limit frame 604 is provided with a limit post 605 that can abut against the robot arm 700. When the robot arm 700 rotates to a preset angle, it will contact the limit post 605 to prevent it from rotating excessively.

[0041] In one embodiment, the output end of the robot 700 is provided with a tray 701 for direct contact and support of the membrane roll. To better fit the cylindrical end face of the membrane roll, the tray 701 is provided with an arc groove.

[0042] In one embodiment, the receiving surface of the receiving platform 400 is V-shaped. During operation, when the lifting assembly 300 drives the receiving platform 400 to rise to receive the film roll held by the robotic arm 700, the V-shaped inclined surface first contacts and guides the film roll from both sides of its bottom. Under the influence of gravity, the cylindrical surface of the film roll naturally rolls downwards along the V-shaped inclined surface until it stably stops at the bottom center of the V-shaped groove. This process achieves automatic centering and positioning of the film roll on the receiving platform 400. When the transfer cart 200 transports the film roll to the unloading point, the top support assembly 500 actuates, driving one side of the receiving platform 400 to lift it, causing it to tilt as a whole. At this time, the V-shaped receiving surface transforms into an inclined groove with a clear guiding boundary. Under the influence of gravity, the film roll rolls downwards along this V-shaped groove, its rolling trajectory constrained by the two inclined surfaces, thus being guided in a predetermined unloading direction until it smoothly detaches from the receiving platform 400.

[0043] like Figures 4 to 6 As shown, the support frame 8 further includes a frame 1, a support portion 2 located on the side of the frame 1 near the track frame 100, and a fixed seat 11 on the frame 1. The pressure relief assembly is installed in the fixed seat 11, which provides a mounting base for the pressure relief assembly. The clamping part 3 consists of a clamping arm 31 and a connecting rod assembly 32. The end of the clamping arm 31 away from the support portion 2 is hinged to the fixed seat 11, allowing the clamping arm 31 to rotate around the hinge point. The connecting rod assembly 32 is hinged to the arm of the clamping arm 31 and the fixed seat 11. The clamping drive part 4 is connected to the connecting rod assembly 32. By driving the connecting rod assembly 32, the clamping arm 31 can be rotated, thereby adjusting the opening and closing of the clamping groove. The clamping groove is located between the clamping arm 31 and the support portion 2. When the air shaft is placed on the support portion 2, the clamping arm 31 can move closer to the air shaft and cooperate with the support portion 2 to clamp the air shaft.

[0044] In one embodiment, the clamping drive unit 4 includes a first cylinder 41. The linkage assembly 32 is composed of a rotating block 321, which has a first hinge end 322, a second hinge end 323, and a third hinge end 324 arranged in a T-shape. This arrangement facilitates force transmission and motion conversion. The first hinge end 322 is rotatably connected to the fixed base 11, allowing the rotating block 321 to rotate relative to the fixed base 11. The second hinge end 323 is hinged to the piston rod of the first cylinder 41. When the piston rod of the first cylinder 41 extends or retracts, it drives the rotating block 321 to swing. The third hinge end 324 is hinged to the arm of the clamping arm 31 via a connecting plate 325, thereby transmitting the motion of the rotating block 321 to the clamping arm 31 and controlling the rotation of the clamping arm 31. With this linkage mechanism, the opening and closing action of the clamping arm 31 is smoother, improving the reliability of clamping.

[0045] During operation, when clamping of the air shaft is required, the piston rod of the first cylinder 41 extends outward under air pressure. The linear motion of the piston rod is converted into a pushing or pulling force on the rotating block 321 through its hinge point with the second hinge end 323 of the rotating block 321. Since the rotating block 321 is rotatably connected to the fixed seat 11 through its first hinge end 322, this force will cause the rotating block 321 to swing around the axis of the first hinge end 322. The swinging motion of the rotating block 321 is transmitted to the arm of the clamping arm 31 through its third hinge end 324 and the connecting plate 325 hinged thereto. The connecting plate 325 converts the arc swing of the third hinge end 324 of the rotating block 321 into a pulling force on the clamping arm 31, thereby driving the clamping arm 31 to rotate around its hinge point with the fixed seat 11 towards the support part 2, so that the clamping groove gradually closes until the end of the clamping arm 31 is in contact with the surface of the air shaft placed on the support part 2, completing the clamping action. When it is necessary to release the air shaft, the piston rod of the first cylinder 41 retracts, and through the reverse movement of the above-mentioned transmission chain, drives the clamping arm 31 to rotate away from the support part 2, thereby opening the clamping groove.

[0046] In one example, during the clamping operation, to improve clamping efficiency, the end of the clamping arm 31 adjacent to the support portion 2 is bent towards the axis of the clamping groove, forming a hook portion 33. The design of the hook portion 33 allows it to fit more closely to the surface of the air shaft, increasing the contact area and thus reducing the probability of the air shaft slipping during clamping, optimizing the fixing effect. At the same time, to monitor the position of the clamping arm 31, a lower limit block 34 is provided at the end of the clamping arm 31 near the support portion 2, and a first limit switch 35 is provided on the side of the fixing seat 11 near the support portion 2, which is used to detect the positioning status of the lower limit block 34. The first limit switch 35 is electrically connected to the clamp drive unit 4. When the clamping arm 31 rotates to the preset position, the lower limit block 34 triggers the first limit switch 35. The first limit switch 35 can send a signal to control the clamp drive unit 4 to stop moving. This helps to ensure that the clamping arm 31 is accurately positioned, avoids overtravel or undertravel, and improves the accuracy of operation.

[0047] In one example, the support portion 2 includes a mounting base 21 and a support plate 22. The mounting base 21 is connected to the frame 1, and the support plate 22 directly supports the end of the air shaft. To accommodate air shafts of different sizes or for fine-tuning of height, the support plate 22 is provided with at least one elongated groove 23 extending vertically. The elongated groove 23 is connected to the mounting base 21 via a connector, allowing the support plate 22 to be adjusted up and down along the elongated groove 23 and then secured by the connector. A limiting support plate 24 is provided below the support plate 22 on the mounting base 21. The limiting support plate 24 provides bottom support for the support plate 22, preventing it from bending under load and enhancing structural stability.

[0048] like Figures 4 to 6 As shown, the venting assembly 5 further includes a second cylinder 51, which is mounted on the frame 1, and an exhaust pin 52 is disposed at its piston rod. The function of the second cylinder 51 is to drive the exhaust pin 52 to move along the axial direction of the air shaft. After the air shaft is in place, the second cylinder 51 can push the exhaust pin 52 into the exhaust hole of the air shaft to perform the pressure relief operation. This design reduces the difficulty of pressure relief, reduces manual intervention, improves work efficiency, and makes the pressure relief process smoother and easier to control.

[0049] like Figures 4 to 6 As shown, the flap assembly 6 further comprises a housing 61 and a swing arm 62; the flap drive unit 7 includes a third cylinder 71. The housing 61 is located at the bottom of the track frame 100, and the housing 61 has an upward-opening mounting cavity 63 inside. The swing arm 62 is placed at the opening of the mounting cavity 63 and can rotate around the hinge point. The fixed end of the third cylinder 71 is hinged to the mounting cavity 63, and its piston rod is hinged to one end of the swing arm 62. The extension and retraction of the third cylinder 71 can drive the swing arm 62 to rotate. The other end of the swing arm 62 is equipped with a support roller assembly 64 for supporting the bottom of the air shaft. The support roller assembly 64 generally includes rotatable rollers. When the swing arm 62 is raised, the support roller assembly 64 can support the other end of the air shaft and cooperate with the support part 2 on the frame 1 to jointly support the air shaft, thereby providing a stable temporary placement after the air shaft is pulled out and reducing the risk of tipping. The roller assembly 64 can rotate while supporting the air shaft, which allows the air shaft to experience rolling friction rather than sliding friction with the support point when it is positioned or removed. This reduces potential scratches on the surface of the air shaft and makes placing or removing the air shaft onto the roller easier and smoother, helping to protect the air shaft and facilitate operation. The flip-plate assembly 6 is located on the side of the frame 1, forming a span between its support point and the clamping point on the frame 1. This two-point support method significantly improves the anti-tipping moment when the air shaft is placed, significantly improves the placement stability of air shafts with a large length-to-diameter ratio, and reduces the safety hazard of tipping. The housing 61 houses the third cylinder 71, the swing arm 62, and the roller assembly 64. The upward-facing opening of the mounting cavity 63 allows the swing arm 62 to extend the roller assembly 64 for operation. In the non-operating state, the roller assembly 64 can be retracted into the cavity. This design effectively prevents dust, splashes, and other contaminants in the production environment from polluting or interfering with moving parts such as cylinders and hinges, and plays a positive role in improving the service life and operational reliability of core drive components.

[0050] During operation, once the clamping part 3 at the end of the frame 1 clamps and fixes one end of the air shaft, the flip-plate assembly 6 immediately starts. Under the pneumatic drive, the piston rod of the third cylinder 71 begins to extend outward. Since the fixed end of the third cylinder 71 is connected to the wall of the mounting cavity 63 inside the housing 61 via the hinge seat 303, and the end of the piston rod is hinged to one end of the swing rod 62, the linear outward movement of the piston rod will push that end of the swing rod 62, causing the entire swing rod 62 to rotate upward. The rotation of the swing rod 62 drives the roller assembly 64 mounted on its other end to rise synchronously. The roller assembly 64 generally consists of a bracket and freely rotating rollers. When the swing rod 62 rotates to the preset support position, the rising rollers will contact and support the shaft of the air shaft from below. At this time, one end of the air shaft is firmly held by the support part 2 and the clamping part 3 on the frame 1, while the other end or the middle is supported by the roller assembly 64 of the flip plate assembly 6, thus forming a stable support posture with at least two points, so that the air shaft is horizontally and reliably suspended, completing the temporary placement after being unloaded from the production line. When it is necessary to remove the air shaft, the piston rod of the third cylinder 71 retracts, and pulls the swing arm 62 in the opposite direction through the above-mentioned transmission, causing it to drive the roller assembly 64 to rotate downward and return to the opening of the mounting cavity 63.

[0051] In one embodiment, to protect the internal structure and improve safety, a first cover plate 65 is provided on the side of the rocker arm 62 away from the opening of the mounting cavity 63, and the first cover plate 65 can cover part of the mounting cavity 63. A second cover plate 66 is hinged to the end of the first cover plate 65 away from the roller assembly 64. The bottom of the second cover plate 66 contacts the upper edge of the opening of the mounting cavity 63. When the rocker arm 62 rotates, the second cover plate 66 can open and close accordingly to prevent foreign objects from entering the mounting cavity 63. A third cover plate 67 is hinged to the end of the mounting cavity 63 away from the second cover plate 66. The bottom surface of the third cover plate 67 is provided with a roller flap 68 for supporting the roller assembly 64. An elastic reset member 69 for supporting the third cover plate 67 is provided below the roller flap 68 in the mounting cavity 63. The elastic reset member 69 is usually a spring, which can provide cushioning when the roller assembly 64 resets, so that the third cover plate 67 can close automatically, further protecting the internal mechanism and extending its service life.

[0052] The specific working principle is as follows: The swing arm 62 of the flap assembly 6 drives the roller assembly 64 to rotate between rising and falling, and the cover plates are linked accordingly to achieve dynamic protection. When the swing arm 62 is in the lowered reset position, the roller assembly 64 is retracted into the mounting cavity 63. At this time, the first cover plate 65 is fixedly connected to the side of the swing arm 62 facing away from the opening of the mounting cavity 63, covering part of the area above the swing arm 62, forming the first static protection. The second cover plate 66 is connected to the far end of the first cover plate 65 by its hinge shaft. Its bottom edge hangs down naturally under the action of gravity, slightly touching or maintaining a small gap with the upper edge of the opening edge of the mounting cavity 63, thereby basically sealing the longitudinal opening formed between the swing arm 62 and the side wall of the mounting cavity 63, which helps to prevent larger foreign objects from falling vertically. The third cover plate 67 is installed at the end of the mounting cavity 63 away from the second cover plate 66 by its proximal hinge shaft (corresponding to the position above the roller assembly 64 when it is fully retracted). Under the support of the elastic reset member 69 (such as a spring), the third cover plate 67 remains slightly open upwards, and the roller flap 68 connected to its bottom surface supports the reset roller assembly 64, on the one hand restricting its free shaking, and on the other hand, together with the third cover plate 67, sealing the opening at this end of the mounting cavity 63.

[0053] When the third cylinder 71 drives the rocker arm 62 to rotate upward, the rocker arm 62 drives the first cover plate 65 to rotate synchronously, and the included angle between the first cover plate 65 and the second cover plate 66 changes. Due to the contact constraint between the bottom edge of the second cover plate 66 and the upper edge of the mounting cavity 63, the second cover plate 66 will rotate adaptively, and its top will rotate around the hinge axis, so that the second cover plate 66 gradually opens, making way for the rotation of the rocker arm 62. At the same time, because it is always in contact with the upper edge of the cavity, it can still provide some shielding for the side of the opening. Meanwhile, as the rocker arm 62 rises, the roller assembly 64 gradually disengages from the support of the roller flap 68 and moves out of the mounting cavity 63. The lower part of the third cover plate 67 loses the support of the roller assembly 64 and can slowly and automatically spring open under the action of the elastic reset member 69, keeping the opening at that end open.

[0054] When the rocker arm 62 lowers and resets the roller assembly 64, the process is reversed. At the end of its descent, the roller assembly 64 contacts and presses against the roller flap 68. The elastic reset member 69 is compressed, absorbing impact energy and providing cushioning, allowing the third cover plate 67 to rotate downwards and close, so that the roller assembly 64 can smoothly slide into its final position. Once the roller assembly 64 is fully in place, the third cover plate 67 returns to its closed state and supports the roller assembly 64. At the same time, the rocker arm 62 and the first cover plate 65 reset, causing the second cover plate 66 to rotate back to cover the opening of the mounting cavity 63.

[0055] The overall working principle of this application is as follows: After the film roll completes the winding process on the production line, firstly, the rotating frame 600, located on the side of the track frame 100 near the top support assembly 500, is activated. The piston rod of the push-pull cylinder 603 is hinged to the robot arm 700, driving the two robot arms 700 to rotate around the rotating shaft 601 and move synchronously to the vicinity of the receiving platform 400. The robot arm 700 receives the wound film roll from the winding equipment. The output end of the robot arm 700 is equipped with a support plate 701, on which an arc groove is formed to better fit the end face of the film roll and achieve stable clamping.

[0056] At this point, the transfer carriage 200 begins to move under the drive of the sliding motor assembly 203. The sliding motor assembly 203 is driven by the sprocket mechanism and the pulley block 202, causing the transfer carriage 200 to slide along the length of the track frame 100, precisely positioning the receiving platform 400 directly below the film roll. The lifting assembly 300 is activated, and the scissor lift platform 301 extends, pushing the lifting frame 302 and the receiving platform 400 to rise smoothly and vertically. When the receiving platform 400 rises to contact the bottom of the film roll, the elastic top support 304 provides cushioning to reduce impact. After the receiving platform 400 is in full contact with the bottom of the film roll and bears the weight, the robot arm 700 is released under the drive of the rotating frame 600, and the film roll is completely transferred onto the receiving platform 400. The receiving surface of the receiving platform 400 is V-shaped, which helps the film roll to automatically center and position itself during reception.

[0057] While the film roll is being transferred, the device performs another set of operations on the air shaft that holds the film roll in place. Before the air shaft is pulled out of the film roll, its end is placed on the support frame 8 at one end of the track frame 100, and the clamping drive unit 4 on the support frame 8 starts to work. When the first cylinder 41 is activated, it pushes the rotating block 321 to swing, which in turn drives the clamping arm 31 to rotate around its hinge point with the fixed seat 11 through the connecting plate 325, so that the clamping groove between the clamping part 3 and the support part 2 is closed. The end of the clamping arm 31 near the support part 2 is bent towards the axis of the clamping groove to form a hook part 33 to increase the clamping contact area. When the swing limit block 34 reaches the detection area of ​​the first limit switch 35, after detecting the clamping position, it feeds back to control the clamping drive unit 4 to ensure accurate clamping position.

[0058] After the end of the air shaft is clamped and fixed, the piston rod end of the second cylinder 51 is equipped with an exhaust pin 52. The second cylinder 51 drives the exhaust pin 52 to move axially along the air shaft, inserting it into the exhaust valve of the air shaft to complete the pressure relief operation, causing the key bar that was tightened on the air shaft to retract, making it easier to pull out from the membrane roll later. The pressure relief assembly 5 is integrated on the support frame 8, realizing centralized control of the pressure relief operation.

[0059] After the air shaft releases pressure, the transfer trolley 200 moves the film roll along the track frame 100, gradually separating the film roll from the air shaft. When the film roll is transported to the target unloading point, the top support assembly 500 starts working. The piston rod of the top support cylinder 501 extends, pushing the roller assembly 502 to roll along the guide ramp 402, lifting the side of the receiving platform 400 away from the hinge axis, causing the plane of the receiving platform 400 to tilt around the hinge axis, forming an inclined surface. Under its own weight, the film roll rolls along the inclined V-shaped receiving surface to the lower side, smoothly detaching from the receiving platform 400 and rolling down to the predetermined unloading point, completing the unloading operation. After unloading, the piston rod of the top support cylinder 501 retracts, and the receiving platform 400 returns to horizontal under its own weight or the action of the reset mechanism. The lifting assembly 300 drives the receiving platform 400 to descend. During the descent, the buffer support 305 set on the transfer car 200 contacts the lifting frame 302 to provide buffering and make the descent end smooth.

[0060] After the air shaft separates from the film roll, to maintain the stability of the air shaft and facilitate subsequent processing, the flip-plate assembly 6, located at the bottom of the track frame 100 near the support frame 8, is activated. The third cylinder 71 drives the swing arm 62 to rotate upward, causing the support roller assembly 64 at the other end of the swing arm 62 to support the middle of the air shaft from below or the other end away from the clamping part 3. The support point of the flip-plate assembly 6 and the clamping point on the support frame 8 together form a stable support system with at least two points, keeping the air shaft in a horizontal position, making it easy for the operator to put a new paper core on the air shaft and inflate it.

[0061] After the air shaft is processed, two robotic arms 700, driven by the rotating frame 600, re-grab the air shaft and return it to the winding equipment station to await the next winding process. The entire device achieves efficient and stable transfer and processing of film rolls and air shafts through the coordinated operation of its components.

[0062] In summary, by utilizing the three openable clamping parts and the support frame 8, active clamping of the air shaft end is achieved, expanding the clamping contact surface and effectively reducing the risk of rotation or dislodgement of the air shaft during fixing. The addition of a swingable flap assembly 6 provides auxiliary support for the other end of the air shaft. This support, together with the clamping point at the frame 1, forms a stable support system, significantly improving the anti-tipping performance of the air shaft during temporary placement. Simultaneously, when the transfer cart 200 approaches below the film roll, the flap assembly 6 resets under the drive of the flap drive unit 7, avoiding collisions with the transfer cart 200. The film roll is horizontally conveyed via a large-plane receiving platform 400. Compared to suspended clamping transport, this method has a lower center of gravity and a wider support surface, significantly enhancing its anti-sway and anti-tipping capabilities during transport. Integrating the depressurization component 5 onto the support frame 8 integrates the depressurization operation, simplifies the operation process, and helps improve the continuity of the production line. The tilt angle of the receiving platform 400 is adjusted by the top support component 500, and the film roll is automatically rolled off by gravity. This unloading method has a simple structure, the film roll rolls roll off smoothly, and effectively reduces the risk of damage to its surface.
