Aircraft seat skirting apparatus

Abstract

This utility model discloses an aircraft seat skin edging device, including a worktable and a glue tank. A lower mold is fixedly installed at the top center of the worktable. This utility model employs cutters and take-up rollers. During the skin edging of the aircraft seat, the take-up rollers wind and pull the skin, moving the glued, unused skin into a mating groove for easy contact with the seat back panel. After edging, multiple cutters sequentially cut off excess skin around the back panel, facilitating back panel preparation. Excess skin is then wound and rolled up by the take-up rollers, simultaneously pulling away any unused skin at the rear. This reduces the need for frequent skin handling, lowering labor intensity and offering advantages such as ease of operation and high practicality.

Description

Technical Field

[0001] This utility model relates to the field of seat production equipment technology, specifically to equipment for edge covering of aircraft seats. Background Technology

[0002] Aircraft seats are designed specifically for civil aviation and installed in aircraft cabins to provide passengers with a safe and comfortable riding experience. Aircraft seats generally consist of a backrest, seat cushion, armrests, and support bars. As people's living standards improve, the requirements for aircraft seats are also increasing. The seat cushions of aircraft seats need to be edged, and the edged parts of aircraft seats are mainly made of soft materials such as leather, polyester, and cotton.

[0003] The existing public technology application number CN201921756869.3 describes a seat edge-wrapping device that uses an arc-shaped support plate and a pressing mechanism to replace the action of workers pressing the edge-wrapping material of the seat cushion by hand, thereby reducing the contact between the worker's hands and the edge-wrapping material and thus reducing the chance of worker injury. Workers can wrap and press the edge-wrapping material by rotating the tray through the cooperation of the arc-shaped support plate and the pressing mechanism, which greatly improves the safety of workers.

[0004] However, the above-mentioned patent still has certain drawbacks in use: although it can reduce the pressure of personnel on the edge binding material, the subsequent edge binding operation still needs to be carried out manually, which increases the labor intensity of personnel. At the same time, the edge binding material needs to be frequently replaced and aligned, which further increases the number of operation steps. The processing is time-consuming and laborious, making the overall use effect not ideal.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an aircraft seat skin edge-wrapping device, which has the advantages of labor-saving operation, high edge-wrapping efficiency, and strong practicality, thereby solving the problems mentioned in the background technology.

[0007] To achieve the advantages of labor-saving operation, high edge-binding efficiency, and strong practicality mentioned above, the specific technical solution adopted by this utility model is as follows:

[0008] An aircraft seat upholstery binding device includes a workbench and a glue tank. A lower mold is fixedly installed at the top center of the workbench. The bottom of both sides of the lower mold has symmetrically formed grooves, and pressure rollers are rotatably connected to the top of each groove. A butt joint groove is formed inside the lower mold, and a binding groove is formed at the bottom center of the butt joint groove. Push plates are symmetrically installed at the top of both sides of the binding groove, with one end of each push plate penetrating through one side of the lower mold and connected to a first cylinder. Several sets of cutting grooves are formed around the outer side of the binding groove inside the lower mold, and grooves are formed at the bottom of each cutting groove. A winding frame and a feeding frame are respectively installed on both sides of the lower mold at the top of the workbench. The frame includes shafts mounted on the surface of both the winding frame and the unwinding frame. One end of the shaft on the winding frame passes through one side of the winding machine and is connected to a servo motor. A winding roller and an unwinding roller are mounted on the shaft. Several sets of guide rods are symmetrically welded to both ends of the lower die on the surface of the worktable. A moving plate is slidably connected between the guide rods. Several sets of second cylinders are mounted around the top of the moving plate. The output end of the second cylinder passes through one side of the moving plate and is connected to a cutter. The cutter has several sets, divided into transverse and longitudinal sections. The longitudinal cutter has symmetrical slots on its surface, and the height of the slots is greater than that of the transverse cutter.

[0009] Furthermore, a support plate is fixedly installed at the top of the guide rod, and a third cylinder is installed at the middle of the top of the support plate. The output end of the third cylinder is connected to the lifting rod, and one end of the lifting rod passes through one side of the support plate and is connected to the moving plate.

[0010] Furthermore, an upper mold is installed at the bottom center of the movable plate, and several sets of positioning grooves are opened on the bottom surface of the upper mold. The positioning groove structure is adapted to the components in the aircraft seat that need to be edge-wrapped.

[0011] Furthermore, the dimensions of the edge-sealing groove are the same as those of the upper mold.

[0012] Furthermore, springs are symmetrically sleeved on both sides of the movable plate at the outer periphery of the guide rod.

[0013] Furthermore, a glue tank is installed on one side of the top of the support plate, and one end of the glue tank is connected to a glue pump via a pipe.

[0014] Furthermore, a coating plate is mounted on one side of the feeding rack at the top of the workbench, and several sets of glue-drip heads are evenly installed on the bottom surface of the coating plate. The glue-drip heads are connected to the glue pump through pipes, and a scraper is installed at an angle on one side of the coating plate.

[0015] Furthermore, the adhesive-coated plate is arranged parallel to the skin.

[0016] Compared with the prior art, the present invention provides an aircraft seat skin edging device, which has the following beneficial effects:

[0017] (1) This utility model uses a cutter and a take-up roller. When wrapping the skin of an aircraft seat, the take-up roller can wrap and pull the skin, so that the unused skin after gluing can be moved into the docking groove, which is convenient for subsequent contact with the back panel of the aircraft seat. This is to realize the skin wrapping operation. After the wrapping is completed, the excess skin around the back panel can be cut off by the downward movement of multiple sets of cutters. At this time, the back panel can be easily cut. The excess skin can be wrapped and pulled up under the pull of the take-up roller. At the same time, the unused skin at the back is pulled, so that the personnel do not need to operate the skin frequently, which can reduce the labor intensity of the personnel and improve the practicality of the device. It has the advantages of easy operation and strong practicality.

[0018] (2) This utility model adopts an upper mold and a lower mold. When covering the edge of the aircraft seat, the upper mold can fix the component to be covered, while the lower mold can bear and limit the skin. Subsequently, the skin can be moved into the lower mold by the movement of the winding roller, and the edge covering operation of the component can be realized by the movement of the upper mold. At the same time, the operation of the first cylinder can adhere the side skin to the component, thereby realizing the full edge covering operation and improving the overall edge covering quality. Since the entire edge covering process does not require manual pressing and alignment, it can ensure the overall work efficiency and facilitate better use. It has the advantage of high edge covering efficiency. Attached Figure Description

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0027] According to an embodiment of the present invention, an aircraft seat skin edging device is provided.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, the aircraft seat skin edging device according to an embodiment of the present invention includes a workbench 1 and a glue tank 20. A lower mold 2 is fixedly installed at the top center of the workbench 1. Grooves are symmetrically opened at the bottom of both sides of the lower mold 2, and pressure rollers 7 are rotatably connected to the top of the grooves. A docking groove 4 is opened inside the lower mold 2, and an edging groove 3 is opened at the bottom center of the docking groove 4. Push plates are symmetrically installed at the top of both sides of the edging groove 3, and one end of the push plate passes through one side of the lower mold 2 and is connected to a first cylinder 5. Several sets of knife grooves 6 are opened around the outside of the edging groove 3 inside the lower mold 2, and grooves are opened at the bottom of the knife grooves 6. A winding frame 8 and a feeding frame 23 are respectively installed on both sides of the lower mold 2 at the top of the workbench 1. Shafts are installed on both the surface of the die and the surface of the feeding rack 23. One end of the shaft on the winding rack 8 passes through one side of the winding machine and is connected to the servo motor 10. The winding roller 9 and the feeding roller 24 are respectively installed on the shaft. Several sets of guide rods 11 are symmetrically welded to both ends of the lower die 2 on the surface of the worktable 1. A moving plate 12 is slidably connected between the guide rods 11. Several sets of second cylinders 15 are installed around the top of the moving plate 12. The output end of the second cylinder 15 passes through one side of the moving plate 12 and is connected to the cutter 27. The cutter 27 has several sets, divided into transverse and longitudinal sections. The longitudinal cutter 27 has symmetrical slots on its surface, and its height is greater than that of the transverse cutter 27. The lower die 2 is fixed to the center of the worktable 1 by bolts. The lower die 2 is internally reinforced with... The machined cavity features a stepped design with a docking groove 4 whose width matches the width of the skin, enabling pre-positioning of the skin. A binding groove 3 is located at the bottom. A knife groove 6 is evenly distributed around the binding groove 3. Pressure rollers 7 are mounted on the slots on both sides of the lower die 2 via bearings. Pressure rollers 7 are coated with a silicone layer to reduce damage to the skin and provide tension to ensure the skin enters the processing area smoothly. A winding frame 8 and a feeding frame 23 are symmetrically mounted on both sides of the worktable 1. A servo motor 10 is connected to a shaft via a coupling. A keyway is machined on the shaft surface to mate with the winding roller 9 / feeding roller 24. The servo motor 10 achieves closed-loop control of the winding tension, ensuring slippage-free skin conveying. The transverse cutter 27 is made of tungsten steel, and the longitudinal cutter 27 is designed with a double-edged structure, connected to the second cylinder 1 via a cylinder connecting seat. 5. The lateral cutter 27 is 10mm higher than the transverse cutter 27, enabling step-by-step cutting. Step-by-step cutting reduces instantaneous load, and the slotted design avoids tool interference. The first cylinder 5 is installed on the side of the lower mold 2 via a flange. A polyurethane pressure block is pasted on the front end of the push plate. The third cylinder 18 is vertically installed on the support plate 14. The lifting rod 19 is made of hollow aluminum tube. The push plate pressure is controlled by a proportional valve to achieve precise control of the skin's lateral edge-wrapping pressure. During the processing, in the skin conveying stage: the servo motor 10 starts → the feeding roller 24 releases the skin → the glue is applied by the glue plate 22 → the pressure roller 7 tensions and positions the skin → it enters the docking groove 4. In the edge-wrapping forming stage: the third cylinder 18 drives the upper mold 16 to press down → the back plate presses into the skin → the first cylinder 5 pushes the lateral edge-wrapping → the pressure is held for 30 seconds to complete the bonding.Precision cutting stage: The longitudinal cutter 27 descends 15mm to cut the longitudinal edge → the transverse cutter 27 descends 10mm to cut the transverse edge → the waste material is automatically wound into the take-up roller 9; Cyclic operation stage: The take-up roller 9 pulls the new skin into the station → the upper mold 16 resets → the single-piece cycle reduction is completed.

[0029] In one embodiment, a support plate 14 is fixedly installed at the top of the guide rod 11, and a third cylinder 18 is installed at the middle of the top of the support plate 14. The output end of the third cylinder 18 is connected to the lifting rod 19. One end of the lifting rod 19 passes through one side of the support plate 14 and is connected to the moving plate 12. The guide rod 11 is a chrome-plated optical shaft, and four rods are symmetrically welded to the workbench 1. The moving plate 12 is made of cast aluminum alloy, and linear bearings are installed at the four corners to form a sliding pair with the guide rod 11.

[0030] In one embodiment, an upper mold 16 is installed at the bottom center of the movable plate 12. Several sets of positioning grooves 17 are opened on the bottom surface of the upper mold 16. The structure of the positioning grooves 17 is adapted to the components in the aircraft seat that need to be edge-wrapped. The upper mold 16 is a contoured aluminum alloy mold. The positioning grooves 17 are CNC machined at the bottom. The contour of the positioning grooves 17 is reverse-formed according to the 3D scanning data of the aircraft seat back panel. The fit gap is ≤0.1mm. The positioning grooves 17 are embedded with rubber pads to increase the clamping friction of the components.

[0031] In one embodiment, the size of the edge banding groove 3 is the same as the size of the upper mold 16.

[0032] In one embodiment, springs 13 are symmetrically sleeved on both sides of the movable plate 12 at the outer periphery of the guide rod 11. The springs 13 are rectangular cross-section helical springs 13, which absorb the impact energy when the upper mold 16 closes and reduce equipment vibration and noise.

[0033] In one embodiment, a glue tank 20 is installed on one side of the top of the support plate 14. One end of the glue tank 20 is connected to a glue pump 21 through a pipe. The glue pump 21 is equipped with a PID flow controller to control the glue output. The glue tank 20 has a double-layer insulation structure. The glue pump 21 is a gear pump. The glue supply pipeline is equipped with a heating belt to maintain the glue temperature.

[0034] In one embodiment, a coating plate 22 is mounted on one side of the feeding rack 23 at the top of the workbench 1. Several sets of dispensing heads 25 are evenly installed on the bottom surface of the coating plate 22. The dispensing heads 25 are connected to the glue pump 21 through pipes. A scraper 26 is installed at an angle on one side of the coating plate 22. The coating plate 22 is mounted on the side of the feeding rack 23 by a bracket. The dispensing heads 25 have a needle valve structure and are connected to the glue pump 21 through PU hoses. The scraper 26 is at a 45° angle to the skin, which facilitates the uniform application of glue film.

[0035] In one embodiment, the adhesive coating plate 22 is arranged parallel to the skin to facilitate better adhesive application.

[0036] Working principle: In actual use, the operator can install the take-up roller 9 and the unloading roller 24 on the corresponding take-up frame 8 and unloading frame 23, respectively. The unloading roller 24 has the skin required for edging. Then, the skin on the unloading roller 24 can be passed through the slot on the surface of the lower mold 2 and connected to the take-up roller 9. Subsequently, the servo motor 10 on one side of the take-up roller 9 can drive the take-up roller 9 to rotate, thereby realizing the movement of the skin. When the skin moves, the glue pump 21 above it can continuously discharge the glue in the glue tank 20 through the glue drip head 25. At this time, the glue can drip onto the surface of the skin. As the skin moves, the glue on its surface will... The adhesive is spread evenly on the surface of the skin by the scraper 26, which then moves the adhesive-coated skin into the mating groove 4. Simultaneously, the operator inserts the backrest of the aircraft seat into the positioning groove 17 in the upper mold 16 using the plastic parts on its surface, thus securing the backrest. The operation of the third cylinder 18 then lowers the entire upper mold 16, allowing the backrest to fit against the skin. As the third cylinder 18 continues to operate, the backrest compresses the skin, causing it to insert into the edge-sealing groove 3. At the same time, the first cylinder 5 can operate... The push plate on the surface moves closer to the back panel, pressing the side skin against the back panel. At this point, the sides and ground of the back panel are in contact with the skin, achieving the pressing and bonding operation between the skin and the back panel. After a certain amount of pressing, the skin is firmly adhered to the surface of the back panel using adhesive. Then, the sequential operation of multiple sets of second cylinders 15 drives the cutters 27 at different positions downwards, cutting off excess skin. Because the longitudinal cutter 27 is taller than the transverse cutter 27 and has grooves on its surface, the grooves on the longitudinal cutter 27 can be inserted into the transverse cutter 27 as it falls. The cutting blade 27 ensures that multiple sets of cutting blades 27 can operate smoothly and cut the skin smoothly. After the aircraft seat is edged, the upper mold 16 can be returned to its original position to move the processed back panel upwards, making it convenient for personnel to unload the material. Then, the winding roller 9 runs to wind up the excess skin and move the unused skin to the docking groove 4 for subsequent edge-wrapping operations. The entire operation does not require frequent loading and unloading of skin, which can effectively reduce the labor intensity of personnel and improve the overall edge-wrapping efficiency, making it easier to use. The device as a whole has the advantages of easy operation, high edge-wrapping efficiency, and strong practicality.
