Description

Technical Field

[0001] This invention relates to the field of massage bed assembly technology, and more specifically, to an intelligent suspension conveying system for the massage bed assembly process. Background Technology

[0002] A massage bed is a type of professional furniture used for massage, physiotherapy, and beauty services. It typically consists of a bed frame, foam padding, leather upholstery, headrest, armrests, and various adjustment mechanisms. With the rapid development of the health industry, the market demand for massage beds continues to grow, placing higher demands on their assembly efficiency and quality. The assembly process of a massage bed involves multiple steps, including frame assembly, foam bonding, leather upholstery, accessory installation, and functional testing. These steps need to be completed sequentially in different assembly areas, representing a typical multi-station collaborative operation. Traditional assembly methods often employ floor-mounted assembly lines or manual transport, which suffers from problems such as large floor space requirements, overlapping logistics paths, and high handling costs, making them unsuitable for the demands of modern large-scale production.

[0003] To address the aforementioned issues, some massage bed manufacturers have begun introducing intelligent suspended conveyor systems for the assembly process. Existing intelligent suspended conveyor systems for massage bed assembly typically include a suspension track, a conveyor trolley, a drive unit, a control system, and several assembly stations. The operation involves suspending the massage bed frame or semi-finished product along the suspension track, and then having the conveyor trolley transport it sequentially to each assembly area. Each assembly area is equipped with corresponding parts and assembly tools, and workers or robotic arms complete the assembly work at that station during system pauses. These systems typically employ programmable logic controllers for centralized control, combined with radio frequency identification (RFID) technology for tracking and scheduling the conveyor trolleys, and possess some data acquisition capabilities, enabling semi-automated conveying during the massage bed assembly process. Compared to traditional ground-based conveying methods, suspended conveyor systems effectively utilize the upper space of the workshop, reduce ground-based logistics interference, and to a certain extent improve the continuity of the assembly line and the utilization rate of the space.

[0004] Existing intelligent suspended conveyor systems for massage bed assembly processes still have significant shortcomings in practical applications. Specifically, during the suspended conveying process, these systems need to sequentially transport the massage bed frame or semi-finished products to multiple assembly areas for component assembly, and the assembly cycle of each assembly area varies. For example, the frame assembly station is relatively quick, while the leather covering station, due to its complex process and delicate operation, typically requires a longer time. Existing systems mostly adopt a fixed-cycle mode for conveyor speed control and station stop strategies, meaning that the conveyor speed and intermittent downtime are uniformly set according to the assembly cycle of the slowest station across all assembly areas. While this rigid control method ensures sufficient working time for each station, it leads to significant efficiency losses: when the conveyor line passes a station with a shorter processing time, the system still needs to wait for the fixed cycle time before continuing, resulting in unnecessary idle time; and when overall production capacity needs to be increased, it cannot intelligently speed up and dynamically adjust to the actual differences in the operating cycles of different assembly areas. Furthermore, in multi-model mixed-line production scenarios, the assembly time for different massage bed models at the same workstation varies. Existing systems lack the ability to flexibly adjust the conveyor rhythm based on real-time workstation status and product information, resulting in insufficient flexibility in the assembly line and difficulty in adapting to efficient and customized production needs. Therefore, how to achieve intelligent matching and dynamic optimization of the conveyor system and the assembly cycle of each workstation during the massage bed assembly process has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies: In existing intelligent suspension conveying systems for massage bed assembly, massage bed components need to be transported to multiple assembly areas during the suspension conveying process. After being transported to the assembly area, these components require a certain assembly cycle. Since the assembly cycle varies in each assembly area, the fixed conveying speed and intermittent downtime are determined based on the cycle of the slowest assembled component. This results in low assembly efficiency, meaning that it cannot intelligently and flexibly adjust to improve efficiency based on the different assembly cycles of components in different assembly areas after speed increases. The proposed intelligent suspension conveying system for massage bed assembly addresses these shortcomings.

[0006] The specific technical solution is as follows: An intelligent suspension conveying system is used in the massage bed assembly process, including a closed-loop conveying track. Multiple suspension hooks are mounted on the closed-loop conveying track, distributed along the track. The hooks are powered and mounted on the track via a speed-regulating base. The hooks can rotate in a closed loop along the track, suspending massage bed components. The speed-regulating base includes a mounting base and a base body. The mounting base is mounted on the base body and is used for detachable installation of the suspension hooks. The base body includes multiple unit speed-regulating bases, stacked together and slidably assembled. Telescopic components are installed between the unit speed-regulating bases to control the movement of the unit speed-regulating bases. The degree of mutual sliding and misalignment between the components is controlled. During the closed-loop rotation of the conveyor track, the number of multiple unit speed-regulating bases is adjusted according to the different assembly cycle of different assembly parts in different assembly areas. By controlling the degree of mutual sliding and misalignment between these multiple unit speed-regulating bases, the speed-regulating base body can either delay the deceleration of the mounting seat through the mounting seat or accelerate the speed-regulating base body through the mounting seat to enter the assembly area earlier and then reverse misalignment, thereby increasing the dwell time of the suspension hook carrying the massage bed parts in the assembly area; or the speed-regulating base body can accelerate the dwell time of the suspension hook through the mounting seat to shorten the dwell time of the suspension hook carrying the massage bed parts in the assembly area. This enables intelligent and flexible adjustment for different assembly cycles of parts in different assembly areas, improving assembly efficiency.

[0007] In the technical solution of the present invention, the unit speed regulating base includes a guide plate, which is elongated; a guide groove is provided on the guide plate, which is distributed along the main body of the guide plate; the cross-section of the guide groove is convex; a telescopic component is assembled inside the guide groove, and the telescopic component is used to control the degree of mutual sliding misalignment between multiple unit speed regulating bases by utilizing the guide groove.

[0008] In the technical solution of the present invention, the telescopic component includes a third electric telescopic rod, one end of which is fixed to the end of the guide groove, and the third electric telescopic rod is assembled along the distribution direction of the guide groove; the third electric telescopic rod and the side wall of the guide groove do not contact each other; the other end of the third electric telescopic rod is fixed with a guide slider, which is slidably assembled inside the guide groove.

[0009] In the technical solution of the present invention, the cross-section of the guide slider is convex, and the cross-sectional dimensions of the guide slider match the cross-sectional dimensions of the guide groove; both the inner and outer surfaces of the guide slider are smooth.

[0010] In the technical solution of the present invention, one end of the guide slider extending out of the guide groove is fixed to the adjacent unit speed regulating base by a connecting plate.

[0011] In the technical solution of the present invention, the closed-loop conveying track is equipped with multiple support beams, which are used to support the closed-loop conveying track; each support beam is provided with a corresponding support leg below it, and the support leg is detachably mounted on the ground.

[0012] In the technical solution of the present invention, a power device is installed on the closed-loop conveying track, and the power device is connected to the closed-loop conveying track by power transmission; the power device is used to drive the closed-loop conveying track to rotate in a closed loop.

[0013] In the technical solution of the present invention, the mounting base includes a mounting body and a stabilizer. The mounting body is slidably assembled on the unit speed-regulating base and is used for detachable installation of the suspension hook. The stabilizer is assembled on the side wall of the mounting body and is used to stabilize the massage bed components during speed change and prevent the massage bed components from shaking and colliding with each other.

[0014] In the technical solution of the present invention, the stabilizing component includes a first electric telescopic rod and a vertical plate. The first electric telescopic rod and the vertical plate are assembled together in a vertical manner. The end of the first electric telescopic rod away from the vertical plate is fixed to the mounting plate, and the mounting plate is fixed to the side wall of the mounting base.

[0015] In the technical solution of the present invention, a plurality of unit support rods are installed on the upright plate, and the plurality of unit support rods are distributed at equal intervals along the upright plate; the unit support rod includes a support pad and a second electric telescopic rod, the second electric telescopic rod being fixed vertically on the upright plate; the second electric telescopic rod and the first electric telescopic rod are distributed in parallel, and the support pad is fixed to the end of the second electric telescopic rod away from the upright plate.

[0016] In summary: During the massage bed assembly process, a closed-loop conveyor track is activated, which drives multiple suspension hooks along with massage bed components to move sequentially into different assembly areas for assembly. During the closed-loop rotation of the conveyor track, the system dynamically adjusts the number of unit speed-regulating bases used based on the different assembly cycle times of the parts in different assembly areas. By controlling the relative sliding misalignment between these unit speed-regulating bases, the system achieves delayed deceleration or acceleration of the speed-regulating base relative to the mounting base. Specifically, when it is necessary to increase the dwell time of the suspension hooks in a certain assembly area, the speed-regulating base slows down the suspension hooks via the mounting base; when it is necessary to shorten the dwell time, the speed-regulating base speeds up the suspension hooks via the mounting base, allowing them to enter the next assembly area earlier, and then completes the rhythm adjustment through reverse misalignment reset. Through this mechanism, the system can intelligently and flexibly adjust the assembly cycle for different assembly areas, significantly improving assembly efficiency. Simultaneously, when the suspension hooks suspend the massage bed components, the stabilizing components utilize multiple unit support rods on the upright plate to abut against the surface of the massage bed components. As the closed-loop conveyor track moves the suspension hooks and massage bed components and undergoes a speed change process, multiple unit support rods on the upright plate provide stable support from multiple points, effectively resisting the swaying caused by inertial forces and preventing components from colliding with each other. Furthermore, the overall distance between the upright plate and the massage bed components can be adjusted by extending and retracting the second electric telescopic rod to accommodate different thicknesses; the extension and retraction of the first electric telescopic rod allows independent control of the extension and retraction of unit support rods in one or more localized areas, thereby achieving precise support for massage bed components of different shapes, sizes, and center of gravity positions.

[0017] The beneficial effects of this invention compared to the prior art are as follows:

[0018] 1. The closed-loop conveyor track is activated, which drives multiple suspension hooks along with massage bed components to move sequentially into different assembly areas for assembly. During the closed-loop rotation of the conveyor track, the number of multiple unit speed-adjustable bases is adjusted according to the different assembly cycle of parts in different assembly areas. By varying the degree of sliding and misalignment between these speed-adjustable bases, the speed-adjustable bases either slow down the suspension hooks behind the mounting bases or speed up the suspension hooks before entering the assembly area and then reversing, thus increasing the dwell time of the suspension hooks carrying the massage bed components in the assembly area; or the speed-adjustable bases can speed up the suspension hooks through the mounting bases to shorten the dwell time of the suspension hooks carrying the massage bed components in the assembly area. This achieves intelligent and flexible adjustment for different assembly cycles of parts in different assembly areas, improving assembly efficiency.

[0019] 2. When the massage bed components are suspended by the hooks, the stabilizing components use multiple unit support rods on the upright plate to abut against the massage bed components. As the closed-loop conveyor track moves multiple hooks along with the massage bed components, they sequentially enter different assembly areas. During the speed change process of the hooks and massage bed components, the multiple unit support rods on the upright plate ensure the stability of the massage bed components, preventing them from swaying and colliding due to inertia. Simultaneously, the distance between the upright plate and the massage bed components can be adjusted by extending and retracting the second electric telescopic rod, and the extension and retraction of the first electric telescopic rod can be used to extend and retract multiple unit support rods in one or more locations, thus supporting massage bed components of different types and sizes.

[0020] 3. The precise speed adjustment of the speed-regulating base makes the speed change process of massage bed components when entering and leaving the assembly area more controllable, providing a clear support timing for the stabilizer; the stabilizer can provide targeted multi-point support during the most intense speed change phase, thereby maximizing its anti-sway effect; the efficient support of the stabilizer eliminates the risk of massage bed components shaking, allowing the speed regulation mechanism to more boldly implement high acceleration and large speed difference speed change strategies, further shortening the transfer time between workstations and improving the overall conveying cycle time;

[0021] 4. The stabilizer and speed-regulating base form a positive cycle, jointly improving the conveying efficiency and operational stability of the assembly line to a level that is difficult for traditional systems to achieve. In addition, the number of speed-regulating bases used per unit and the telescopic adjustment of the support rods per unit form a modular synergy. When more precise speed control is required, the number of speed-regulating bases per unit can be increased, resulting in a smoother speed change process. The stabilizing mechanism can correspondingly reduce the investment in support rods, simplifying control. When stronger support stability is required, the number of support rods used per unit can be increased. The improved stability allows the speed-regulating base to implement faster speed change strategies. This dynamic balance enables the system to flexibly optimize between "precise speed control" and "support stability" according to different production scenarios, achieving optimal resource allocation and significantly improving adaptability to multi-model mixed-line production.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0033] Example 1, as Figure 1 , Figure 2 , Figures 5-7 As shown: The massage bed assembly process uses an intelligent suspension conveying system, including a closed-loop conveying track 2. Multiple suspension hooks 4 are mounted on the closed-loop conveying track 2. The multiple suspension hooks 4 are distributed along the closed-loop conveying track 2. The suspension hooks 4 are powered and mounted on the closed-loop conveying track 2 through a speed-regulating base 7. The multiple suspension hooks 4 can rotate in a closed loop along the closed-loop conveying track 2. The suspension hooks 4 are used to suspend massage bed components 6.

[0034] The massage bed component 6 in the figure is not fully depicted in detail due to its variety and size. As it is existing technology, its detailed structure can be found in existing literature and journals, and it can also be purchased directly from the market. It is not the subject of this invention and will not be described in detail here.

[0035] The structure of the closed-loop conveyor track 2 itself is existing technology, which can be purchased directly on the market, assembled by purchasing parts, or understood by consulting journals, etc. Those skilled in the art can choose to purchase it according to their own needs; the closed-loop conveyor track 2 is not the subject of this application and will not be described in detail here.

[0036] Among them, the suspension hook 4 is existing technology, which can be directly purchased on the market and applied directly; it is also a device that can be freely selected by those skilled in the art according to their own needs.

[0037] The speed regulating base 7 includes a mounting base 8 and a speed regulating base body 9. The mounting base 8 is assembled on the speed regulating base body 9 and is used for the detachable installation of the suspension hook 4. The speed regulating base body 9 includes multiple unit speed regulating bases 91, which are stacked together and slidably assembled with each other. Each unit speed regulating base 91 is equipped with a telescopic component, which is used to control the degree of sliding misalignment between the multiple unit speed regulating bases 91.

[0038] Therefore, given that the assembly cycle of parts varies in each assembly zone, the fixed conveyor speed and intermittent downtime are determined based on the cycle of the slowest assembled part, resulting in low assembly efficiency. This means that intelligent and flexible adjustments cannot be made to improve efficiency after speed increases to accommodate the different assembly cycles of parts in different assembly zones. This application addresses this issue by:

[0039] The closed-loop conveyor track 2 is activated, which drives multiple suspension hooks 4, along with massage bed components 6, to move sequentially into different assembly areas for assembly. During the closed-loop rotation of the closed-loop conveyor track 2, the number of multiple unit speed-regulating bases 91 is adjusted according to the different assembly cycle of different parts in different assembly areas. The degree of mutual sliding and misalignment between the multiple unit speed-regulating bases 91 is used to either delay the suspension hooks 4 by the mounting base 8, or accelerate the suspension hooks 4 by the mounting base 8 before they enter the assembly area and then reverse misalignment, thereby increasing the dwell time of the suspension hooks 4 carrying the massage bed components 6 in the assembly area; or to accelerate the suspension hooks 4 by the mounting base 8, thereby shortening the dwell time of the suspension hooks 4 carrying the massage bed components 6 in the assembly area (this process can be specifically referred to...). Figure 7This enables intelligent and flexible adjustments to be made for different assembly cycles of parts in different assembly areas, thereby improving assembly efficiency.

[0040] Example 2 is based on Example 1 with the following additions: Figure 5 and Figure 6 As shown: The unit speed-regulating base 91 includes a guide plate 92, which is elongated; a guide groove 93 is provided on the guide plate 92, which is distributed along the main body of the guide plate 92; the cross-section of the guide groove 93 is convex; a telescopic component is assembled inside the guide groove 93, and the telescopic component is used to control the degree of mutual sliding misalignment between multiple unit speed-regulating bases 91 using the guide groove 93.

[0041] like Figure 5 and Figure 6 As shown: The telescopic component includes a third electric telescopic rod 95, one end of which is fixed to the end of the guide groove 93. The third electric telescopic rod 95 is assembled along the distribution direction of the guide groove 93. The third electric telescopic rod 95 and the side wall of the guide groove 93 do not contact each other. The other end of the third electric telescopic rod 95 is fixed with a guide slider 94, which is slidably assembled inside the guide groove 93.

[0042] like Figure 6 As shown: the cross-section of the guide slider 94 is convex, and the cross-sectional dimensions of the guide slider 94 match the cross-sectional dimensions of the guide groove 93; both the inner and outer surfaces of the guide slider 94 are smooth.

[0043] like Figure 5 and Figure 6 As shown: One end of the guide slider 94 extending out of the guide groove 93 is fixed to the adjacent unit speed-regulating base 91 by a connecting plate.

[0044] The closed-loop conveying track 2 is equipped with multiple support beams 3, which are used to support the closed-loop conveying track 2; each support beam 3 is provided with a corresponding support leg 5 below it, and the support leg 5 is detachably mounted on the ground.

[0045] like Figure 1 As shown: The closed-loop conveying track 2 is equipped with a power device 1, which is connected to the closed-loop conveying track 2 via power transmission; the power device 1 is used to drive the closed-loop conveying track 2 to rotate in a closed loop.

[0046] The power unit 1 is existing technology and can be purchased directly from the market, assembled from parts, or researched through journals. Those skilled in the art can choose to purchase it according to their needs. The closed-loop conveying track 2 is not protected by this application and will not be described in detail here. Of course, as is well known to those skilled in the art, the power unit 1 of this invention provides power to drive the closed-loop conveying track 2 to rotate normally in a closed loop. As is well known to those skilled in the art, the power unit 1 is commonplace and belongs to conventional means or common knowledge. It will not be described in detail here. Those skilled in the art can choose to arbitrarily configure it according to their needs or convenience.

[0047] Example 3 is based on Example 2 with the following additions: Figures 2-4 As shown: The mounting base 8 includes a mounting body 81 and a stabilizer 82. The mounting body 81 is slidably mounted on the unit speed-regulating base 91 (the mounting body 81 is fixed on the guide slider 94 and slidably mounted on the guide groove 93 of the unit speed-regulating base 91 through the guide slider 94). The mounting body 81 is used for detachable installation of the suspension hook 4. The stabilizer 82 is mounted on the side wall of the mounting body 81. The stabilizer 82 is used to stabilize the massage bed components 6 during speed change and prevent the massage bed components 6 from shaking and colliding with each other.

[0048] like Figure 3 and Figure 4 As shown: The stabilizer 82 includes a first electric telescopic rod 822 and a vertical plate 823. The first electric telescopic rod 822 and the vertical plate 823 are assembled together in a vertical position. The end of the first electric telescopic rod 822 away from the vertical plate 823 is fixed to the mounting plate 821. The mounting plate 821 is fixed to the side wall of the mounting base 81.

[0049] like Figure 4 As shown: Multiple unit support rods 824 are installed on the upright plate 823, and the multiple unit support rods 824 are distributed at equal intervals along the upright plate 823; each unit support rod 824 includes a support pad 8241 and a second electric telescopic rod 8242, the second electric telescopic rod 8242 is fixed vertically on the upright plate 823; the second electric telescopic rod 8242 and the first electric telescopic rod 822 are distributed in parallel, and the support pad 8241 is fixed to the end of the second electric telescopic rod 8242 away from the upright plate 823.

[0050] Therefore, when the suspension hook 4 suspends the massage bed component 6, the stabilizer 82 uses multiple unit support rods 824 on the upright plate 823 to abut against the massage bed component 6; when the closed-loop conveyor track 2 drives multiple suspension hooks 4 together with the massage bed component 6 to move and enter different assembly areas in sequence, during the speed change process of the suspension hooks 4 and the massage bed component 6, the multiple unit support rods 824 on the upright plate 823 can ensure the stability of the massage bed component 6 and avoid the massage bed component 6 from shaking and colliding with each other due to inertia; at the same time, by extending and retracting the second electric telescopic rod 8242, the distance between the upright plate 823 and the massage bed component 6 can be adjusted, and by extending and retracting the first electric telescopic rod 822, multiple or multiple unit support rods 824 can be extended and retracted in one or more places to achieve support for massage bed components 6 of different types and sizes.

[0051] It should be further explained that the first electric telescopic rod 822, the second electric telescopic rod 8242 and the third electric telescopic rod 95 can be replaced by hydraulic telescopic rods or pneumatic telescopic rods, etc., which are all existing technologies. Their specific structures are not limited, as long as they can meet the telescopic requirements. At the same time, they can be purchased directly on the market, and there are relevant descriptions in corresponding journal articles. They are not what this invention is trying to protect, and will not be elaborated on here.

[0052] In summary: During the massage bed assembly process, the closed-loop conveyor track 2 is activated, which drives multiple suspension hooks 4, along with massage bed components 6, to move and sequentially enter different assembly areas for assembly operations. During the closed-loop rotation of the conveyor track 2, the system dynamically adjusts the number of unit speed-regulating bases 91 used based on the differences in the assembly cycle of components in different assembly areas. By controlling the relative sliding misalignment between multiple unit speed-regulating bases 91, the system achieves delayed deceleration or acceleration of the speed-regulating base 9 relative to the mounting base 8. Specifically, when it is necessary to increase the dwell time of the suspension hook 4 in a certain assembly area, the speed-regulating base 9 slows down the suspension hook 4 through the mounting base 8; when it is necessary to shorten the dwell time, the speed-regulating base 9 accelerates the suspension hook 4 through the mounting base 8, allowing it to enter the next assembly area earlier, and then completes the rhythm adjustment through reverse misalignment reset. Through this mechanism, the system can intelligently and flexibly adjust the assembly cycle for different assembly areas, significantly improving assembly efficiency. Meanwhile, when the suspension hook 4 suspends the massage bed component 6, the stabilizer 82 uses multiple unit support rods 824 on the upright plate 823 to abut against the surface of the massage bed component 6. When the closed-loop conveyor track 2 drives the suspension hook 4 and the massage bed component 6 to move and undergo a speed change process, the multiple unit support rods 824 on the upright plate 823 provide stable support from multiple points, effectively resisting the shaking caused by inertial force and preventing the components from colliding with each other. In addition, by extending and retracting the second electric telescopic rod 8242, the overall distance between the upright plate 823 and the massage bed component 6 can be adjusted to accommodate different thicknesses; by extending and retracting the first electric telescopic rod 822, the extension and retraction of one or more local areas of unit support rods 824 can be independently controlled, thereby achieving precise support for massage bed components 6 with different shapes, sizes and center of gravity positions.

[0053] The precise speed adjustment of the speed-regulating base 9 makes the speed change process of the massage bed component 6 when entering and leaving the assembly area more controllable, providing a clear support timing for the stabilizer 82; the stabilizer 82 can provide targeted multi-point support during the most intense speed change phase, thereby maximizing its anti-sway effect; the efficient support of the stabilizer 82 eliminates the risk of swaying of the massage bed component 6, allowing the speed regulation mechanism to more boldly implement high acceleration and large speed difference speed change strategies, further shortening the transfer time between workstations and improving the overall conveying cycle time.

[0054] The stabilizer 82 and the speed-regulating base 9 form a positive cycle, jointly improving the conveying efficiency and operational stability of the assembly line to a level that is difficult for traditional systems to achieve. In addition, the number of speed-regulating bases 91 used per unit and the telescopic adjustment of the support rod 824 form a modular synergy. When more precise speed control is required, the number of speed-regulating bases 91 can be increased, resulting in a smoother speed change process. The stabilizing mechanism can correspondingly reduce the number of support rods, simplifying control. When stronger support stability is required, the number of support rods 824 can be increased. The improved stability allows the speed-regulating base 9 to implement a faster speed change strategy. This dynamic balance enables the system to flexibly optimize between "precise speed control" and "support stability" according to different production scenarios, achieving optimal resource allocation and significantly improving adaptability to multi-model mixed-line production.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
