Description

Technical Field

[0001] This application relates to the field of sofa bed assembly line technology, and more specifically, this application relates to a sofa bed production and assembly equipment and a sofa bed thereof. Background Technology

[0002] A sofa bed production assembly line is a production line specifically designed for manufacturing sofa beds. It typically includes a series of production equipment and processes used to process raw materials into various sofa bed components and ultimately assemble them into a complete product. The design and optimization of sofa bed production assembly lines are crucial for improving production efficiency, reducing costs, and ensuring product quality. With the development of technology, modern sofa bed production assembly lines are increasingly trending towards automation and intelligence. A search revealed an existing patent publication number: CN113043012A, which discloses a multi-unit sofa production line, including multiple individual sofa assembly lines, each equipped with a first conveying device and a second conveying mechanism. Multiple individual sofa assembly lines for producing individual sofas are arranged along the transmission direction of the second conveying mechanism. The first conveying device of each individual sofa assembly line has multiple corresponding process stations arranged along its feeding direction. The components of the individual sofas are conveyed along the feeding direction on the first conveying device, sequentially passing through each process station and completing the corresponding process at each station until assembly is complete to form an individual sofa. Furthermore, the multiple individual sofas are conveyed and converged on the second conveying mechanism via the first conveying device, and finally, the multiple individual sofas undergo a final assembly process on the second conveying mechanism to be assembled into a complete sofa set. This improves the automation level of multi-unit sofa production, saves manpower and time, and increases production efficiency. In the process of realizing this application, the inventors discovered the following problems with the existing technology: When assembling sofas using an assembly line, the structure of the assembly line itself results in a single conveying direction. This means that the sofa itself cannot move while it is moving on the assembly line, and the assembly nodes cannot be adjusted according to the position of the installers. Therefore, before using the assembly line, the basic connection points between the sofas need to be connected first, and then the sofas are assembled by the assembly line.

[0003] Therefore, during the assembly process, because the sofa's position is fixed, the workers often need to leave their posts to find the assembly point. This can easily affect the rhythm of the assembly line's transport process, thus impacting the production efficiency of the assembly line.

[0004] Therefore, a sofa bed production and assembly equipment and a sofa bed thereof are proposed to address the above problems. Summary of the Invention

[0016] The technical effects and advantages of this application are as follows: 1. Compared with the prior art, this sofa bed production and assembly equipment and its sofa bed, during the assembly process, places the sofa bed parts in the assembly placement rack according to corresponding directions. The sofa bed consists of a support base, a first bed board, a second bed board, a first lateral extension plate, and a second lateral extension plate. Therefore, when assembling the sofa bed, the sofa bed parts containing the support base, the first bed board, and the second bed board are placed on the assembly placement rack and driven by the assembly placement rack. Then, they move along the feeding mechanism to the turning conveyor mechanism. The feeding table moves the sofa bed parts, and the structure of the assembly placement rack limits and aligns the sofa bed parts, so that the sofa bed parts are located in the designated positions within the assembly placement rack. This allows the sofa bed parts to be directly exposed to the operator's working position, enabling the operator to directly assemble the sofa bed parts.

[0017] 2. Compared with the prior art, the sofa bed production and assembly equipment and the sofa bed thereof, through the turning conveyor mechanism, enable the assembly line assembly to be separated through the first conveyor table and the second conveyor table, and change the assembly position of the sofa by flipping the components to complete the connection of all sofa assembly.

[0018] 3. Compared with existing technologies, this sofa bed production and assembly equipment and its sofa bed feature a re-engaging chuck that secures the swinging sofa panel, allowing for easy adjustment of the panel's tilt angle to suit various housing requirements. A circulating collection component, in conjunction with tightening rollers, lays the sofa cover. After one stage of use, a second electric turntable moves the sofa cover, causing it to be rolled up and a new cover to be released, thus providing a new cover for the sofa bed structure. This transfers bacteria attached to the sofa cover. After the sofa cover is used, the circulating collection component and the sofa bed structure are sorted, allowing for centralized sterilization of the fabric within the collection component. This reduces bacterial adhesion, protects the sofa bed's usability, and preserves its quality. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example 1

[0022] As attached Figures 1 to 15 The sofa bed production assembly line shown includes a turning conveyor mechanism 1, a material conveying mechanism 2, and an assembly shelf 4. The material conveying mechanism 2 is placed at the feeding end of the turning conveyor mechanism 1, and a lifting unloading worktable 3 is provided on the side of the turning conveyor mechanism 1 away from the material conveying mechanism 2. The assembly shelf 4 is provided on the side of the turning conveyor mechanism 1 away from the material conveying mechanism 2, and sofa bed parts waiting to be assembled are placed on the top of the assembly shelf 4.

[0023] The steering and conveying mechanism 1 includes a dual-position material distribution platform 7, a first conveying platform 8, a second conveying platform 9, a flipping component 6, and a bidirectional material merging platform 10. The first conveying platform 8 and the second conveying platform 9 are respectively arranged on the side of the dual-position material distribution platform 7 away from the material conveying mechanism 2. The flipping component 6 for flipping and assembling the shelf 4 is placed at the center of the first conveying platform 8 and the second conveying platform 9. The bidirectional material merging platform 10 is arranged on the side of the flipping component 6 away from the dual-position material distribution platform 7.

[0024] The material conveying mechanism 2 includes a second slide 29, a receiving platform 30, a material supply table 5, and a reversing component 201. Receiving platforms 30 are provided on both sides of the two sets of second slides 29, and material supply tables 5 are provided on the side of the receiving platforms 30 furthest from the second slides 29. A reversing component 201 is provided between the two sets of second slides 29. During assembly, the parts of the sofa bed structure are placed in the assembly shelf 4 according to their corresponding directions. As can be seen from the sofa bed structure in Embodiment 2, the sofa bed... The machine bed structure consists of a support base 45, a first sofa board 46, a second sofa board 47, a side control guard plate 48, and a circulation collection component 61. The material conveying mechanism 2 has three symmetrically arranged material supply tables 5, which are used to assemble the first sofa board 46, the side control guard plate 48, and the circulation collection component 61 respectively. At this time, the assembly shelf 4 moves towards the turning conveyor mechanism 1 via the material conveying mechanism 2. Meanwhile, the first set of material supply tables 5 assembles the first sofa board 46 and the second sofa board 47. 47 is placed on the support base 45 above the assembly shelf 4. Then the assembly shelf 4 continues to move forward and stops. At this time, the construction personnel connect the first sofa board 46 to the support base 45 for assembly. Then, different material supply tables 5 move the parts of the sofa bed structure and limit and align the parts of the sofa bed structure through the structure of the assembly shelf 4, so that the parts of the sofa bed structure are located in the designated position within the assembly shelf 4, so that the parts of the sofa bed structure are directly exposed to the operation position of the construction personnel, so that the construction personnel can directly assemble the parts of the sofa bed structure. Then, when the assembly shelf 4 moves to the center of the second set of material supply tables 5 and the third set of material supply tables 5 and contacts the reversing component 201, the assembly position of the sofa bed structure on the assembly shelf 4 is changed. During the entire assembly process, the loss rate of various plates, connectors, etc. in the sofa bed structure is reduced. Therefore, the assembly line directly corresponds the assembly area to the area easily operated by the construction personnel, which can effectively reduce the material loss problem by 7%.

[0025] In a preferred embodiment, the assembly shelf 4 includes a fixed frame 401, a drive placement chamber 402, a barrier frame 403, a plate placement base 39, a plate placement groove 40, and a plate limiting bracket 41. Both sides of the fixed frame 401 are provided with drive placement chambers 402 for driving pulleys to rotate. The fixed frame 401 and the drive placement chambers 402 are connected by bolts to form a detachable structure. A plate placement base 39 is located at the center of the two sets of drive placement chambers 402, and the plate placement base 39 and the drive... Each of the moving placement chambers 402 has a plate placement groove 40 at its center, and a plate limiting bracket 41 is installed on the upper inner wall of the plate placement groove 40. A blocking bracket 403 is installed above the fixed frame 401, and the fixed frame 401 and the blocking bracket 403 are connected by a bearing to form a rotatable connection structure. The placement direction of the part is determined by the position of the blocking bracket 403. The plate limiting bracket 41 includes a clamping arm 42, a connecting mounting part 43, and a triggering rod 44. The end of the clamping arm 42... The end is placed inside the connecting mounting part 43. A trigger rod 44 is provided above the connecting mounting part 43. When the trigger rod 44 is pressed and squeezes the clamping arm 42 to the end inside the connecting mounting part 43, the clamping arm 42 rotates along the horizontal axis and drives the clamping arm 42 to move. When the trigger rod 44 is pressed and squeezes the clamping arm 42 to the end inside the connecting mounting part 43, the clamping arm 42 moves. The placement support base 45, the first sofa board 46 and the second sofa board 47 waiting to be assembled are placed on the placement plate base 39 of the assembly shelf 4 in sequence. Then, when the assembly shelf 4 is placed above the material conveying mechanism 2 and waiting to be conveyed, the construction personnel connect the placement support base 45 and the first sofa board 46 to fix the base structure used for external connection. After the construction personnel complete the assembly between the placement support base 45 and the first sofa board 46, the assembly shelf 4 drives the pulley to move along the material conveying mechanism 2 through the motor in the drive placement chamber 402.

[0026] In a preferred embodiment, the material supply platform 5 includes a conveying fixed frame 11, a fixed base 12, a feeding platform 13, a first slide rail 14, a sliding connecting frame 15, a receiving bracket 16, a discharging bracket 17, an adjusting base 18, and a rotating bracket 19. The fixed base 12 is bolted to the bottom of the conveying fixed frame 11, and the conveying fixed frame 11 and the fixed base 12 are detachable via bolts. The feeding platform 13, connected to the material conveying mechanism 2, is mounted above the conveying fixed frame 11. The first slide rail 14 is mounted on the upper surface of the feeding platform 13, and the sliding connecting frame 15 is slidably connected above the first slide rail 14. A receiving bracket 16 is bolted to the side end face of the connecting frame 15, and the sliding connecting frame 15 and the receiving bracket 16 are connected by bolts to form a detachable structure. A discharge bracket 17 is provided on the side of the receiving bracket 16 away from the material conveying mechanism 2, and an adjusting base 18 is installed below the discharge bracket 17. A rotating bracket 19 is installed below the adjusting base 18. When the receiving bracket 16 and the feeding platform 13 are combined, the rotating bracket 19 drives the adjusting base 18 to rotate, causing the discharge bracket 17 on the adjusting base 18 to enter the groove provided on the feeding platform 13. This causes the sliding connecting frame 15 to move along the slide rail to align the receiving bracket 16 with the discharge bracket 17. Then, when... After the assembly shelf 4 moves along the material conveying mechanism 2 to the feeding range of the material supply platform 5, the lateral control guard plate 48 placed on the unloading bracket 17 is driven by the rotating bracket 19, causing the rotating bracket 19 to drive the connected adjusting base 18 to rotate, and causing the adjusting base 18 to drive the unloading bracket 17 to be flush with the feeding platform 13. Then, the sliding connecting frame 15 drives the receiving bracket 16 to move through the first slide rail 14, so that the receiving bracket 16 is inserted into the center of the lateral control guard plate 48 and the unloading bracket 17, and the lateral control guard plate 48 is carried away by the receiving bracket 16. Then, the receiving bracket 16 moves to the very end, at which point the receiving bracket 16 passes through the bottom... The electric push of the part tilts the lateral control guard plate 48 on the receiving bracket 16 and pushes it into the interior of the plate placement grooves 40 on both sides of the assembly shelf 4. As the lateral control guard plate 48 moves into the interior of the plate placement grooves 40, it presses the trigger rod 44 of the plate limiting bracket 41, and the trigger rod 44 presses the end of the clamping arm 42 in the connecting mounting member 43. Then the clamping arm 42 swings along the connecting mounting member 43 and rotates to press the lateral control guard plate 48, thereby limiting the lateral control guard plate 48 inside the assembly shelf 4, so that the lateral control guard plate 48 contacts the support base 45.

[0027] In a preferred embodiment, the flipping component 6 includes a movable bracket 20, a connecting base 21, a limiting block 22, an alignment toothed plate 23, a drive base 24, a drive compartment 25, a flipping compartment 26, a plug-in connecting sleeve 27, and a second motor compartment 28. Both sides of the movable bracket 20 are bolted with the connecting base 21, and both sides of the inner wall of the movable bracket 20 are fitted with the alignment toothed plate 23. The drive base 24 meshes with the teeth of the alignment toothed plate 23. When the drive base 24 is driven to move horizontally, the output end of the drive base 24 engages with the alignment toothed plate 25. The teeth of the 3 mesh and move, and a drive housing 25 is installed above the drive base 24. A flipping housing 26 for driving the assembly shelf 4 to flip is provided above the drive housing 25. A plug-in connecting sleeve 27 is provided at the flipping end of the flipping housing 26. A second motor housing 28 for driving the plug-in connecting sleeve 27 to rotate is provided above the flipping housing 26. The flipping housing 26 also includes a clamping claw 2601 and a moving sliding groove 2602. The moving sliding groove 2602 is provided on the side of the clamping claw 2601 away from the second conveyor table 9. When After the clamping claw 2601 completes clamping, and moves up and down along the sliding groove 2602, the shelving frame 4 is assembled. After the placement of the lateral control guard plate 48 and the second lateral extension plate 4801, the construction personnel assemble the hinges to complete the connection between the lateral control guard plate 48 and the support base 45. The snap-fit ​​ends of the buckles are then installed on the lateral control guard plate 48 and the second sofa board 47, respectively, thus completing the foundation fixation of the bed board. The sofa joint parts inside the shelving frame 4 are then assembled. After assembly, the material conveying... Mechanism 2 sends the assembly shelf 4 into the double-position material distribution table 7 of the turning conveyor mechanism 1. At this time, the sofa cover 51 wrapped in the circulating collection component 61 installed on the material supply table 5 is clamped by the clamping claw 2601, which moves the sofa cover 51 upward and pulls it out of the circulating collection component 61. Then the clamping claw 2601 moves forward and moves the sofa cover 51 toward the work area of ​​the construction personnel so that the construction personnel can dock the sofa cover 51 with the two sets of circulating collection components 61.

[0028] In a preferred embodiment, the dual-position material distribution platform 7 includes a turning table 31, a feeding port 32, a first turning disc 33, a first universal moving disc 34, and a limiting stop 35. The turning table 31 has a pre-installed feeding port 32 at the connection point with the material conveying mechanism 2. A first rotating disc is provided on the side of the feeding port 32 away from the material conveying mechanism 2. First universal moving discs 34 are provided on both sides of the first turning disc 33, and limiting stops 35 are provided on both sides of the feeding port 32 for limiting movement. The first universal moving discs 34 on both sides of the first turning disc 33 are arranged horizontally with the second slide rail 29. For example, the average feeding operation time of the feeding port 32 of the dual-position material distribution platform 7 is 14 seconds. The turning of the first turning disc 33... The operation takes an average of 9 seconds. Then, the assembly shelf 4 enters through the feed port 32. After entering, the push rod in the placement chamber 402 drives the pulley to retract, and the first universal moving plate 34 takes over the connection of the assembly shelf 4. The first universal moving plate 34 moves the assembly shelf 4, moving it above the first steering disc 33. The first steering disc 33 then raises the assembly shelf 4, causing it to turn and bring the connecting ends of the first sofa panel 46 and the second sofa panel 47 closer to the worker. The worker then assembles the hinges at the connection point of the first sofa panel 46 and the second sofa panel 47, completing the connection and paving the way for subsequent... The flipping component 6 is prepared for flipping. Then, the first universal moving plate 34 on the double-position dispensing platform 7 drives the assembly shelf 4 to move towards the first conveyor platform 8. When the assembly shelf 4 enters the first conveyor platform 8 and contacts the slide rail, the push rod in the drive placement chamber 402 is reset, the pulley is ejected and connected to the slide rail, and the assembly shelf 4 is moved again, so that the assembly shelf 4 moves into the interior of the first conveyor platform 8. Then, the assembly shelf 4 and the flipping component 6 are aligned during the movement. Then, the height adjustment of the insertion connecting sleeve 27 of the flipping component 6 is aligned with the connecting post of the assembly shelf 4. Then, the insertion connecting sleeve 27 is pushed forward, so that the insertion connecting sleeve 27 connects the connecting post. The assembly shelf 4 is connected by locking the connecting post with the teeth inside the plug-in connecting sleeve 27. Then, the plug-in connecting sleeve 27 is lifted upward by the hydraulic rod 204, causing the plug-in connecting sleeve 27 to move the assembly shelf 4. Then, the motor in the second motor compartment 28 rotates, causing the plug-in connecting sleeve 27 to rotate, causing the plug-in connecting sleeve 27 to rotate the assembly shelf 4. Then, the support base 45 and the first sofa board 46 in the assembly shelf 4 are restricted by the blocking frame 403, so that after the assembly shelf 4 is rotated, the first sofa board 46 and the second sofa board 47 will be perpendicular to each other. At this time, the construction personnel connect the support corner to the support base 45 through the gap of the placement base 39.Then, the snap-fit ​​end of the side control panel 48 and the fastening end of the second sofa panel 47 are joined together to complete the assembly. Actual testing showed that, under the same conditions of skilled workers and material supply, the assembly line can assemble an average of 10% to 15% more sofa beds per hour than a normal conveyor belt. With skilled workers and sufficient material supply, this assembly line can produce an additional 45 to 70 sofa beds per day compared to a standard production line.

[0029] In a preferred embodiment, a second universal moving disc 36 for moving the assembly shelf 4 is provided above each of the two sets of second universal moving discs 36, and a second steering disc 37 is provided at the center of the two sets of second universal moving discs 36. The first steering disc 33 and the second steering disc 36 have the same structure. Then, the flipping component 6 drives the assembly shelf 4 to reset, and the first conveying table 8 moves the conveying fixed frame 11 to the inside of the two-way material gathering table 10.

[0030] In a preferred embodiment, the lifting unloading workbench 3 includes a lifting platform 301 and a receiving platform 38. The receiving platform 38 is located on the side of the lifting platform 301 away from the steering and conveying mechanism 1. After the assembly rack 4 separates from the completed assembly at the receiving platform 38, it re-enters the assembly line by steering and waits for parts to be redistributed for assembly. The reversing assembly 201 includes an electric rotating disk 202, a connector 203, and a hydraulic rod 204. The connector 203 for rotating the assembly rack 4 is bolted to the top of the electric rotating disk 202. The hydraulic rod 204 for lifting is connected to the bottom of the electric rotating disk 202. After the assembly rack 4 separates from the completed assembly at the receiving platform 38, it re-enters the assembly line by steering and waits for parts to be redistributed for assembly. When parts are to be reassigned for assembly, the bidirectional material handling platform 10 sends the assembly shelving 4 from the first conveyor platform 8 and the second conveyor platform 9 to the top of the lifting unloading worktable 3 via the second universal moving plate 36 and the second rotating plate. Then, the lifting unloading worktable 3 lifts and lowers to align the assembly shelving 4 with the receiving platform 38. The receiving platform 38 then completes the corresponding separation, and the assembly shelving 4 moves along the slide rail on the receiving platform 38 and re-enters the assembly line to wait for the parts to be placed. When the assembly shelving 4 moves above the reversing component 201, the hydraulic rod 204 pushes the electric rotating plate 202 to move upward. Then, the electric rotating plate 202 drives the assembly shelving 4 to rotate and change the assembly position on the assembly shelving 4.

[0031]

[0032] In this embodiment 1, when producing sofa beds, with the same materials and operators, the time required to produce the same type of sofa bed is less than the time required by the existing production line.

[0033] The implementation principle of this application embodiment is as follows: During the assembly process, the parts of the sofa bed structure itself are placed in the assembly shelf 4 according to their corresponding directions. As can be seen from the sofa bed structure in Embodiment 2, the sofa bed structure consists of a support base 45, a first sofa board 46, a second sofa board 47, a side control guard plate 48, and a circulation collection component 61. The material supply platform 5 in the material conveying mechanism 2 is symmetrically arranged in three sets, which are used to assemble the first sofa board 46, the side control guard plate 48, and the circulation collection component 61 respectively. At this time, the assembly shelf 4 moves to the position of the turning conveying mechanism 1 through the material conveying mechanism 2. At this time, the first set of material supply platforms 5 places the first sofa board 46 and the second sofa board 47 on the assembly shelf 4. The support base 45 is then placed on the assembly shelf 4, which continues to move forward and pauses. At this time, the construction workers connect the first sofa board 46 to the support base 45 for assembly. Then, different material supply tables 5 move the parts of the sofa bed structure and limit and align the parts of the sofa bed structure through the structure of the assembly shelf 4, so that the parts of the sofa bed structure are located in the designated position within the assembly shelf 4, so that the parts of the sofa bed structure are directly exposed to the operation position of the construction workers, allowing the construction workers to directly assemble the parts of the sofa bed structure. Then, when the assembly shelf 4 moves to the center of the second set of material supply tables 5 and the third set of material supply tables 5 and contacts the reversing component 201, the assembly position of the sofa bed structure on the assembly shelf 4 is changed. When the trigger rod 44 is pressed and squeezes the end of the clamping arm 42 within the connecting mounting part 43, it drives the clamping arm 42 to move. The placement support base 45, the first sofa board 46, and the second sofa board 47, which are waiting to be assembled, are placed sequentially on the placement plate base 39 of the assembly shelf 4. Then, when the assembly shelf 4 is placed above the material conveying mechanism 2 and waiting to be conveyed, the construction personnel connect the placement support base 45 and the first sofa board 46 to fix the base structure used for external connection. After the construction personnel complete the assembly between the placement support base 45 and the first sofa board 46, the assembly shelf 4 moves along the material conveying mechanism 2 by driving the pulleys through the motor in the drive placement chamber 402. Then, after the assembly shelf 4 moves along the material conveying mechanism 2 to the feeding range of the material supply platform 5, the lateral control guard plate 48 placed on the unloading bracket 17 is driven by the rotating bracket 19, causing the rotating bracket 19 to drive the connected adjusting base 18 to turn, and causing the adjusting base 18 to drive the unloading bracket 17 to be flush with the feeding platform 13. Then, the sliding connecting frame 15 drives the receiving bracket 16 to move through the first slide rail 14, so that the receiving bracket 16 is inserted into the center of the lateral control guard plate 48 and the unloading bracket 17, and the lateral control guard plate 48 is taken away by the receiving bracket 16. Then, after the receiving bracket 16 moves to the very end, the receiving bracket 16 is then... The electric push at the bottom tilts the lateral control guard plate 48 on the receiving bracket 16 and pushes it into the interior of the plate placement grooves 40 on both sides of the assembly shelf 4. As the lateral control guard plate 48 moves into the interior of the plate placement grooves 40, it presses the trigger rod 44 of the plate limiting bracket 41, and the trigger rod 44 presses the end of the clamping arm 42 in the connecting mounting part 43. Then the clamping arm 42 swings along the connecting mounting part 43 and rotates to press the lateral control guard plate 48, thereby limiting the lateral control guard plate 48 inside the assembly shelf 4 so that the lateral control guard plate 48 contacts the support base 45. Furthermore, the tilting compartment 26 also includes a clamping claw 2601 and a sliding groove 2602. The sliding groove 2602 is provided on the side of the clamping claw 2601 away from the second conveyor table 9. After the side control guard plate 48 and the second side extension plate 4801 are placed, the construction personnel assemble the hinges to complete the connection between the side control guard plate 48 and the support base 45. The snap-fit ​​ends of the buckles are installed on the side control guard plate 48 and the second sofa board 47 respectively to complete the basic fixation of the bed board. Then, the sofa joint parts in the shelf 4 are assembled. After assembly is completed, the material conveying mechanism 2 sends the assembly shelf 4 into the double-position material distribution platform 7 of the turning conveying mechanism 1. At this time, the sofa cover 51 wrapped in the circulating collection component 61 installed on the material supply platform 5 is clamped by the clamping claw 2601, and the clamping claw 2601 moves the sofa cover 51 upward to pull the sofa cover 51 out of the circulating collection component 61. Then the clamping claw 2601 moves forward to move the sofa cover 51 toward the construction worker's work area so that the construction worker can dock the sofa cover 51 with the two sets of circulating collection components 61. The reversing assembly 201 includes an electric rotating disk 202, a connector 203, and a hydraulic rod 204. The connector 203, bolted to the top of the electric rotating disk 202, is used to rotate the assembly shelf 4. The hydraulic rod 204, used for lifting, is connected to the bottom of the electric rotating disk 202. After the assembly shelf 4 separates from the completed assembly at the receiving platform 38, it re-enters the assembly line by reversing its direction and awaits reassignment of parts for assembly. At this time, the bidirectional material handling table 10, via the second universal moving disk 36 and the second rotating disk, moves the assembly shelf 4 from the first conveyor table 8 and the second conveyor table 9. The parts are fed into the lifting and unloading worktable 3 above the lifting and unloading worktable 3. The lifting and unloading worktable 3 then lifts and lowers to align the assembly shelf 4 with the receiving platform 38. The receiving platform 38 then separates the parts, and the assembly shelf 4 moves along the slide rail on the receiving platform 38 and re-enters the assembly line to wait for the parts to be placed. When the assembly shelf 4 moves above the reversing assembly 201, the hydraulic rod 204 pushes the electric rotating disk 202 to move upward. The electric rotating disk 202 then drives the assembly shelf 4 to rotate and changes the assembly position on the assembly shelf 4. Example 2

[0034] Based on Example 1, the solution in the example will be further described in detail below with reference to the specific working method, such as... Figures 1 to 15 As shown below, see details: In a preferred embodiment, a sofa bed production and assembly equipment, using a production and assembly line according to any one of claims 1-7, comprises a support base 45 placed above an assembly shelf 4, and a first sofa board 46 and a second sofa board 47 placed above the support base 45, symmetrically arranged. Lateral control guard plates 48 are bolted to both sides of the first sofa board 46 and the second sofa board 47. Anti-jamming covers 49 are hinged to both sides of the support base 45, and circulating collection components 61 are provided on the sides of the anti-jamming covers 49. A sofa cover 51 for covering the first sofa board 46 and the second sofa board 47 is wound between the two sets of circulating collection components 61. A tightening roller 53 is provided between 7 to restrict the sofa cover 51, and a reclining support base 60 is provided between the support base 45 and the first sofa panel 46 and the second sofa panel 47. The sofa panel structure of the sofa bed consists of the first sofa panel 46 and the second sofa panel 47. The structures of the first sofa panel 46 and the second sofa panel 47 are the same. Therefore, when the sofa is in use, one side of the sofa panel can be lifted at will to assemble the sofa bed structure. When the bed structure of the sofa bed is to be displayed, the structures of the first sofa panel 46 and the second sofa panel 47 can be laid flat. At this time, the flatness between the two is level with the horizontal. Therefore, when it is used as a bed, the reclining support base 60 keeps the bed surface itself from being uneven.

[0035] In a preferred embodiment, the tail end of the first sofa panel 46 includes a rotating ring 54, a positioning ring 55, a bracket 56, a chuck 57, an adjusting groove 58, and a pushing block 59. The positioning ring 55 is installed inside the rotating ring 54, and a bracket 56 for limiting the swinging of the first sofa panel 46 is movably connected to the outer edge of the positioning ring 55. A chuck 57 for cooperating with the bracket 56 is provided between the two sets of brackets 56, and an adjusting groove 58 is provided on the side of the bracket 56 away from the chuck 57. A pushing block 59 for swinging the bracket 56 is inserted into the groove of the adjusting groove 58. Then, when it is necessary to adjust the sofa panel... When the structure changes, the push block 59 is pushed along the adjusting arc groove 58, causing the push block 59 to push the card holder 56 to rotate, causing the card holder 56 to separate from the engaging end of the chuck 57. This removes the restriction on the rotation of the first sofa panel 46 and the second sofa panel 47. After the angle of the first sofa panel 46 is adjusted, the push block 59 is used to reset the position of the card holder 56, causing the card holder 56 to re-engage with the chuck 57, thus fixing the swinging sofa panel. This allows the tilt angle of the sofa panel to be adjusted at will, making it convenient to adapt to different types of housing and home furnishing requirements.

[0036] In a preferred embodiment, the circulating collection component 61 includes a second electric turntable 50 and a fabric holder 52. The fabric holder 52 is provided at the edge of the second electric turntable 50. When the second electric turntable 50 rotates, the sofa cover 51 moves by rotating the second electric turntable 50. After the sofa cover 51 has moved, the fabric holder 52 contacts the sofa cover 51 and restricts the movement of the sofa cover 51. When the sofa bed structure is used, when the human body is in contact with the sofa bed structure, bacteria from the human body and the environment will adhere to the outer surface of the sofa. At this time, the Hebei Provincial Institute of Quality Inspection and Science was commissioned to conduct tests on household leather sofas that have been used for one year, three years and five years respectively. The report shows that the longer the sofa is used, the more bacteria and mold it contains. Leather sofas used for more than 3 years have mold on their surface that can have adverse effects on the human body. Leather sofas used for 5 years or more, if not properly cleaned and maintained, will have bacterial levels far exceeding the standard. Test results show that a 5-year-old leather sofa has a total bacterial count of 150 per 25 cm² area, compared to 50 per 5 cm² area for a typical toilet seat. Therefore, sofa covers are needed for protection. At this time, the circulating collection component 61, in conjunction with the tightening roller 53, lays the sofa cover 51, completing one... After the initial use, the second electric turntable 50 moves the sofa cover 51, causing the used sofa cover 51 to be rolled up and a new sofa cover 51 to be released, thus completing a new covering of the sofa bed structure sofa cover 51. This transfers bacteria attached to the sofa cover 51 by the human body. After the sofa cover 51 is used, the circulating collection component 61 is sorted with the sofa bed structure, and the fabric in the circulating collection component 61 is centrally sterilized to reduce bacterial adhesion and protect the use of the sofa bed, thus protecting the quality of the sofa bed.

[0037] The implementation principle of this application embodiment is as follows: The sofa bed's sofa panel structure consists of a first sofa panel 46 and a second sofa panel 47. The structures of the first sofa panel 46 and the second sofa panel 47 are identical. Therefore, when the sofa is in use, one side of the sofa panel can be lifted at will to assemble the sofa bed structure. When the bed structure of the sofa bed needs to be realized, the structures of the first sofa panel 46 and the second sofa panel 47 can be laid flat. At this time, the flatness between the two is aligned with the horizontal, so when used as a bed, the bed surface itself will not have any unevenness. Then, when it is necessary to change the structure of the sofa panel, the pushing block 59 is pushed along the adjusting arc groove 58, causing the pushing block 59 to push the card holder 56 to rotate, causing the card holder 56 to separate from the engaging end of the card plate 57. This removes the restriction on the rotation of the first sofa panel 46 and the second sofa panel 47. After the angle adjustment of the first sofa panel 46 is completed, this... When the position of the card holder 56 is reset by pushing block 59, the card holder 56 is re-engaged with the card plate 57, thereby fixing the swinging sofa board. This allows for easy adjustment of the sofa board's tilt angle to suit different types of home furnishings. At this time, the sofa cover 51 is laid out by the circulation collection component 61 in conjunction with the tightening roller 53. After the first stage of use is completed, the sofa cover 51 is moved by the second electric turntable 50, causing the used sofa cover 51 to be rolled up and a new sofa cover 51 to be released. This completes a new covering of the sofa cover 51 of the sofa bed structure, thereby transferring bacteria attached to the sofa cover 51. After the sofa cover 51 is used, the fabric in the circulation collection component 61 is centrally sterilized by classifying it with the sofa bed structure, thereby reducing bacterial adhesion and protecting the use of the sofa bed, as well as preserving the quality of the sofa bed.
