One connecting block has a bidirectional lead screw rotatably connected to its inner cavity. A second motor is mounted on one side of the bidirectional lead screw, and the side of the second motor closest to the adjacent connecting block is fixedly connected to the connecting block.

Description

Technical Field

[0001] This utility model relates to the field of mattress technology, specifically to an automatic stacking device for multi-layer mattress materials. Background Technology

[0002] The automatic multi-layer material stacking equipment for mattresses is a specialized automated device used in the mattress production process. Its main function is to precisely stack multiple layers of different materials (such as foam, spring layers, non-woven fabric, and upholstery) required for mattress production according to a preset order and position to form a complete mattress structure. Through automated control, this equipment achieves efficient and precise stacking of materials, greatly improving the efficiency and quality of mattress production and reducing errors and labor intensity caused by manual operation.

[0003] In existing automated multi-layer mattress material stacking equipment, suction cup adsorption is a commonly used material gripping and stacking method. By generating negative pressure, the mattress material is adsorbed onto the surface of the suction cup, and the material is moved to the designated position for stacking with the help of a robotic arm or other transmission mechanism, thus realizing automated gripping and stacking of mattress materials to a certain extent.

[0004] However, in practical applications, this method has revealed many problems. On the one hand, the suction cup device is prone to falling off. Its suction force is affected by various factors such as the contact area between the suction cup and the material surface, the magnitude of the negative pressure inside the suction cup, and the surface characteristics of the material. When the material surface is uneven, contains dust or oil, or when the sealing performance of the suction cup deteriorates due to prolonged use, the suction force will weaken, thereby increasing the risk of the suction cup falling off. On the other hand, the suction cup device cannot accurately position the mattress. It can usually only grasp and move the material. When stacking the material to the designated position, positional or angular deviations are prone to occur, resulting in an uneven mattress structure. In particular, some mattresses may become skewed during the conveyor process due to uneven conveyor belt speed, uneven elasticity of the material itself, or uneven weight distribution. If the suction cup device is used directly for adsorption and stacking, additional tidying operations are often required for the mattresses, which undoubtedly increases the complexity of the production process and reduces production efficiency. Therefore, we propose an automatic stacking device for multi-layer mattress materials. Utility Model Content

[0005] The purpose of this invention is to provide an automatic stacking device for multi-layer mattress materials to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An automatic stacking device for multi-layer mattress materials includes a drive assembly, a clamping assembly, a placement assembly, a support platform assembly, and a conveyor belt. The drive assembly is located at the end of the conveyor belt, the placement assembly is located at the lower part of the drive assembly near the conveyor belt, and the support platform assembly is located at the lower part of the drive assembly away from the conveyor belt. The clamping assembly includes two connecting blocks, one of which has a bidirectional lead screw rotatably connected to its inner cavity. A second motor is mounted on one side of the bidirectional lead screw, and the side of the second motor near the adjacent connecting block is fixedly connected to the connecting block. The output end of the second motor extends through the surface of the connecting block into its inner cavity. The output shaft is fixedly connected to the bidirectional lead screw. A guide rod 2 is fixedly connected to the inner cavity of another connecting block. Several T-blocks are slidably connected to the inner cavities of both connecting blocks. The bidirectional lead screw is threadedly connected to the adjacent T-block. The guide rod 2 is slidably connected to the adjacent T-block. A connecting frame is fixedly connected to the lower ends of the two T-blocks on the same side. A pressure plate is slidably connected to the inner cavity of the connecting frame. An electric push rod 2 is provided in the middle of the connecting frame. The piston rod output end of the electric push rod 2 is fixedly connected to the upper end of the pressure plate on the same side. Telescopic rod 2 is symmetrically provided in the connecting frame. The piston rod output end of the telescopic rod 2 is fixedly connected to the upper end of the pressure plate on the same side.

[0008] A further improvement of the present invention is that the placement component includes a support plate and two sub-plates. Several support columns are fixedly connected to the lower end of the support plate. Several retraction components are symmetrically fixedly connected to the support plate. An operating rod is rotatably connected to the inner cavity of the support plate. A threaded rod is slidably connected to the inner cavity of the support plate. The threaded rod is threadedly connected to the operating rod.

[0009] Using the above technical solution, the position of the threaded rod can be adjusted by the cooperation of the operating rod and the threaded rod, thereby limiting the size of mattresses of different sizes.

[0010] A further improvement of the present invention is that the shrinking assembly includes a first outer shell fixedly connected to a support plate, a partition slidably connected to the inner cavity of the first outer shell, a connecting rod slidably connected to the inner cavity of the first outer shell, the partition and the connecting rod being fixedly connected, a spring being wound around the outer surface of the connecting rod, the side of the spring closer to the first outer shell being fixedly connected to the first outer shell, the side of the spring away from the first outer shell being fixedly connected to the connecting rod, the inner cavity of the first outer shell being filled with liquid, and a sub-plate being fixedly connected to the adjacent connecting rod.

[0011] Using the above technical solution, under the force of the two connecting frames, the two sub-plates will move towards the support plate. Then, the sub-plates will apply force to the connecting rod, causing the connecting rod to slide in the inner cavity of the outer shell. Then, the water filled in the inner cavity of the partition will flow from one side of the partition to the other side, which can slow down the movement speed of the connecting rod and prevent the two sub-plates from moving too fast, thus affecting the normal use of the device.

[0012] A further improvement of the present invention is that the drive assembly includes a guide rod, a threaded rod, and a motor. Support assemblies are symmetrically arranged on both sides of the guide rod and the threaded rod. The guide rod is fixedly connected to the adjacent support assembly, and the threaded rod is rotatably connected to the adjacent support assembly. Connecting plates are provided on the outer surfaces of both the guide rod and the threaded rod. The guide rod is slidably connected to the adjacent connecting plate, and the threaded rod is threadedly connected to the adjacent connecting plate. The lower ends of the two connecting plates are fixedly connected to the upper ends of the two connecting blocks. The motor is fixedly connected to the adjacent support assembly, and its output shaft is fixedly connected to the threaded rod.

[0013] Using the above technical solution, the motor and the threaded rod work together to move the connecting plate that is threaded to the threaded rod, and then move the entire clamping assembly toward the bearing platform assembly, thus moving the clamping assembly above the rubber plate.

[0014] A further improvement of the present invention is that the support assembly includes a support column, a base plate is fixedly connected to the upper part of the support column, a slide plate is slidably connected to the inner cavity of the base plate, a guide rod is fixedly connected to the adjacent slide plate, a threaded rod is rotatably connected to the adjacent slide plate, a telescopic rod is fixedly connected to one side of the upper end of the base plate, the piston rod output end of the telescopic rod is fixedly connected to the upper part of the slide plate, and an electric push rod is fixedly connected to the side of the upper end of the base plate away from the telescopic rod, the piston rod output end of the electric push rod is fixedly connected to the upper part of the slide plate.

[0015] In the above technical solution, the controller controls the operation of the electric push rod 1, and the piston rod of the electric push rod 1 pushes the slide plate upward, which in turn drives the guide rod 1 and the threaded rod 1 to move upward together, thereby driving the entire clamping assembly to rise, and then driving the mattress material clamped by the clamping assembly to rise together.

[0016] A further improvement of the present invention is that the support platform assembly includes a support frame, with limit blocks symmetrically fixedly connected to the upper end of the support frame, and a rubber plate rotatably connected to the two limit blocks together, and a rotating shaft fixedly connected to the lower middle part of the rubber plate.

[0017] By adopting the above technical solution, the rubber plate can be supported and limited by the rotational connection between the limiting blocks.

[0018] A further improvement of the present invention is that: a second outer shell is fixedly connected to the upper end of the support frame, a rotating shaft is rotatably connected to the second outer shell, a gear is fixedly connected to the middle of the rotating shaft, a rack is slidably connected to the second outer shell, the gear meshes with the adjacent rack, and an electric push rod three is fixedly connected to the upper end of the support frame, the piston rod output end of the electric push rod three is fixedly connected to the rack.

[0019] In the above technical solution, the piston rod of the electric push rod three pushes the rack to move, and then the rack meshes with the adjacent gears, which in turn drives the rotating shaft to rotate. Since the upper end of the rotating shaft is fixedly connected to the lower end of the rubber plate, the rubber plate can be driven to rotate when the rotating shaft rotates.

[0020] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0021] 1. This utility model provides an automatic stacking device for multi-layer mattress materials. Through the cooperation of a motor and a bidirectional lead screw, a T-shaped block threadedly connected to the bidirectional lead screw can be moved. Then, the T-shaped block drives the connecting frame to move. With the cooperation of the two connecting frames, the mattress material placed on the support plate can be aligned to prevent the mattress from tilting. At the same time, the two sides of the mattress will enter the inner cavity of the connecting frame. Then, by running an electric push rod, the piston rod of the electric push rod pushes the pressure plate to slide in the inner cavity of the connecting frame. The pressure plate then presses the two sides of the mattress, thus clamping the mattress material. This prevents the mattress from falling during transport. Moreover, during the clamping process, the mattress is also aligned, reducing additional adjustment time and further improving the overall operating efficiency of the production line.

[0022] 2. This utility model provides an automatic stacking device for multi-layer mattress materials. The device uses a controller to operate an electric push rod three. The piston rod of the electric push rod three pushes a rack to move, and the rack meshes with adjacent gears, driving a rotating shaft to rotate. Since the upper end of the rotating shaft is fixedly connected to the lower end of a rubber plate, the rotating shaft rotates, causing the rubber plate to rotate as well. To avoid displacement or rotation of the mattress material placed on the upper part of the rubber plate, the electric push rod three pushes slowly during rotation, preventing adverse effects from the speed and improving the practicality and versatility of the device.

[0035] The present invention will be further described in detail below with reference to embodiments:

[0036] Example 1

[0037] like Figures 1-4As shown, this utility model provides an automatic stacking device for multi-layer mattress materials. A drive assembly 1 is located at the end of a conveyor belt 5. A placement assembly 3 is located at the lower part of the drive assembly 1 on the side closer to the conveyor belt 5. A support platform assembly 4 is located at the lower part of the drive assembly 1 on the side farther from the conveyor belt 5. The clamping assembly 2 includes two connecting blocks 21. A bidirectional lead screw 23 is rotatably connected to the inner cavity of one of the connecting blocks 21. A second motor 22 is located on one side of the bidirectional lead screw 23. The side of the second motor 22 closest to the adjacent connecting block 21 is fixedly connected to the connecting block 21, and the output end of the second motor 22 extends through the surface of the connecting block 21 into its inner cavity. The output shaft of the second motor 22 is fixed to the bidirectional lead screw 23. The connection includes a guide rod 24 fixedly connected to the inner cavity of another connecting block 21. Several T-blocks 25 are slidably connected to the inner cavities of both connecting blocks 21. A bidirectional screw 23 is threadedly connected to the adjacent T-block 25. The guide rod 24 is slidably connected to the adjacent T-block 25. The lower ends of the two T-blocks 25 on the same side are fixedly connected to a connecting frame 26. A pressure plate 27 is slidably connected to the inner cavity of the connecting frame 26. An electric push rod 28 is provided in the middle of the connecting frame 26. The piston rod output end of the electric push rod 28 is fixedly connected to the upper end of the pressure plate 27 on the same side. Telescopic rods 29 are symmetrically provided in the connecting frame 26. The piston rod output end of the telescopic rod 29 is fixedly connected to the upper end of the pressure plate 27 on the same side.

[0038] In this embodiment, the conveyor belt 5 transports the mattress material, the placement assembly 3 stores the transported mattress material, the drive assembly 1 moves the clamping assembly 2, the support platform assembly 4 stores various mattress materials, and the motor 22, in conjunction with the bidirectional lead screw 23, moves the T-block 25 threadedly connected to the bidirectional lead screw 23. The T-block 25 then moves the connecting frame 26, and with the cooperation of the two connecting frames 26, the mattress material placed on the support plate 31 can be... The mattress is aligned to prevent it from tilting. Simultaneously, the two sides of the mattress enter the inner cavity of the connecting frame 26. Then, by operating the electric push rod 28, the piston rod of the electric push rod 28 pushes the pressure plate 27 to slide within the inner cavity of the connecting frame 26. The pressure plate 27 then presses down on the two sides of the mattress, clamping the mattress material and preventing it from falling during transport. Furthermore, the clamping process also aligns the mattress, reducing additional adjustment time and further improving the overall operating efficiency of the production line.

[0039] Example 2

[0040] like Figure 5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the placement component 3 includes a support plate 31 and two sub-plates 33. A plurality of support columns 36 are fixedly connected to the lower end of the support plate 31. A plurality of retraction components 32 are symmetrically fixedly connected to the support plate 31. An operating rod 34 is rotatably connected to the inner cavity of the support plate 31. A threaded rod 35 is slidably connected to the inner cavity of the support plate 31. The threaded rod 35 is threadedly connected to the operating rod 34.

[0041] In this embodiment, when it is necessary to transport and stack mattress materials, firstly, the conveyor belt 5 is used to transport various mattress materials. Then, the transported materials are conveyed to the upper end of the support plate 31. The threaded rod 35 can limit the materials transported to the upper end of the support plate 31. Through the cooperation of the operating rod 34 and the threaded rod 35, the position of the threaded rod 35 can be adjusted, thereby limiting mattresses of different sizes. Then, the controller controls the motor 22 to run. Through the cooperation of the motor 22 and the bidirectional lead screw 23, the T-block 25 threadedly connected to the bidirectional lead screw 23 can be moved. Then, the T-block 25 drives the connecting frame 26 to move. Then, with the cooperation of the two connecting frames 26, the mattress materials placed on the support plate 31 can be neatly arranged to prevent the mattress from tilting.

[0042] Example 3

[0043] like Figures 6-8 As shown, based on Embodiment 2, this utility model provides a technical solution: Preferably, the shrinking component 32 includes a housing 321 fixedly connected to the support plate 31, a partition 322 slidably connected to the inner cavity of the housing 321, a connecting rod 323 slidably connected to the inner cavity of the housing 321, the partition 322 and the connecting rod 323 being fixedly connected, a spring 324 being wound around the outer surface of the connecting rod 323, the side of the spring 324 near the housing 321 being fixedly connected to the housing 321, the side of the spring 324 away from the housing 321 being fixedly connected to the connecting rod 323, the inner cavity of the housing 321 being filled with liquid, and the sub-plate 33 being fixedly connected to the adjacent connecting rod 323;

[0044] The drive assembly 1 includes a guide rod 11, a threaded rod 12, and a motor 15. Support assemblies 14 are symmetrically arranged on both sides of the guide rod 11 and the threaded rod 12. The guide rod 11 is fixedly connected to the adjacent support assembly 14, and the threaded rod 12 is rotatably connected to the adjacent support assembly 14. Connecting plates 13 are provided on the outer surfaces of both the guide rod 11 and the threaded rod 12. The guide rod 11 is slidably connected to the adjacent connecting plate 13, and the threaded rod 12 is threadedly connected to the adjacent connecting plate 13. The lower ends of both connecting plates 13 are fixedly connected to the upper ends of two connecting blocks 21. The motor 15 is fixedly connected to the adjacent support assembly 14, and its output shaft is connected to... The threaded rod 12 is fixedly connected. The support assembly 14 includes a support column 141. A base plate 142 is fixedly connected to the upper part of the support column 141. A slide plate 145 is slidably connected to the inner cavity of the base plate 142. A guide rod 11 is fixedly connected to the adjacent slide plate 145. The threaded rod 12 is rotatably connected to the adjacent slide plate 145. A telescopic rod 143 is fixedly connected to one side of the upper end of the base plate 142. The piston rod output end of the telescopic rod 143 is fixedly connected to the upper part of the slide plate 145. An electric push rod 144 is fixedly connected to the side of the upper end of the base plate 142 away from the telescopic rod 143. The piston rod output end of the electric push rod 144 is fixedly connected to the upper part of the slide plate 145.

[0045] In this embodiment, under the force of the two connecting frames 26, the two sub-plates 33 will move towards the support plate 31. Then, the sub-plates 33 will apply a force to the connecting rod 323, causing the connecting rod 323 to slide within the inner cavity of the outer shell 321. Water filling the inner cavity of the partition 322 will flow from one side of the partition 322 to the other, slowing down the movement of the connecting rod 323. Simultaneously, it will cause the spring 324 to contract. As the two sub-plates 33 move towards the support plate 31, the sides of the mattress will enter the connecting... Inside the connecting frame 26, the electric push rod 28 is operated, and its piston rod pushes the pressure plate 27 to slide within the connecting frame 26. The pressure plate 27 then presses down on both sides of the mattress, clamping the mattress material and preventing it from falling during transport. Next, the controller controls the electric push rod 144, whose piston rod pushes the slide plate 145 upwards, causing the guide rod 11 and the threaded rod 12 to move upwards together. The entire clamping assembly 2 can be raised, and the mattress material clamped by the clamping assembly 2 can be raised together. Then, through the cooperation of motor 15 and threaded rod 12, the connecting plate 13, which is threaded to the threaded rod 12, can be moved. This can then move the entire clamping assembly 2 towards the support platform assembly 4, moving the clamping assembly 2 above the rubber plate 43. Then, through electric push rod 144, the slide plate 145 slides downward, thereby driving guide rod 11, motor 22, and the entire clamping assembly. 2. Move downwards to place the mattress material held by the clamping component 2 on the upper end of the rubber plate 43. Then, use the electric push rod 28 to drive the pressure plate 27 to reset, releasing the pressure on the mattress material. Next, run the motor 22. With the cooperation of the motor 22 and the bidirectional lead screw 23, drive the T-block 25 to reset, thereby driving the two connecting frames 26 to move away from the mattress material. Finally, reset the device to move the clamping component 2 directly above the placement component 3, and then wait for the new material to be clamped and transported.

[0046] Example 4

[0047] like Figure 9 and Figure 10As shown, based on Embodiment 3, this utility model provides a technical solution: Preferably, the support platform assembly 4 includes a support frame 41, with limit blocks 42 symmetrically fixedly connected to the upper end of the support frame 41, and two limit blocks 42 rotatably connected to a rubber plate 43. A rotating shaft 44 is fixedly connected to the middle of the lower end of the rubber plate 43. A second outer shell 45 is fixedly connected to the upper end of the support frame 41, and the rotating shaft 44 is rotatably connected to the second outer shell 45. A gear 46 is fixedly connected to the middle of the rotating shaft 44, and a rack 47 is slidably connected to the second outer shell 45. The gear 46 meshes with the adjacent rack 47. An electric push rod 48 is fixedly connected to the upper end of the support frame 41, and the piston rod output end of the electric push rod 48 is fixedly connected to the rack 47.

[0048] In this embodiment, when it is necessary to adjust the stacking angle of the materials, the controller controls the operation of the electric push rod 48. The piston rod of the electric push rod 48 pushes the rack 47 to move, and then the rack 47 meshes with the adjacent gear 46, which in turn drives the rotating shaft 44 to rotate. Since the upper end of the rotating shaft 44 is fixedly connected to the lower end of the rubber plate 43, the rotating shaft 44 can drive the rubber plate 43 to rotate. During rotation, in order to avoid displacement or rotation of the mattress material placed on the upper end of the rubber plate 43, the pushing process of the electric push rod 48 is slow to avoid adverse effects caused by the speed.

[0049] The working principle of this automatic multi-layer material stacking device for mattresses will be explained in detail below.

[0050] like Figures 1-10 As shown, when mattress materials need to be conveyed and stacked, firstly, the conveyor belt 5 transports various mattress materials. The transported materials are then conveyed to the upper end of the support plate 31. The threaded rod 35 limits the movement of the materials transported to the upper end of the support plate 31. The position of the threaded rod 35 can be adjusted by the cooperation of the operating rod 34 and the threaded rod 35, thus limiting the movement of mattresses of different sizes. Then, the controller controls the operation of the motor 22. The cooperation between the motor 22 and the bidirectional lead screw 23 moves the T-block 25, which is threadedly connected to the bidirectional lead screw 23. The T-block 25 then moves the connecting frame 26. With the cooperation of the two connecting frames 26, the mattress materials placed on the support plate 31 are neatly arranged, preventing the mattress from tilting.

[0051] Then, under the force of the two connecting frames 26, the two sub-plates 33 will move towards the support plate 31. The sub-plates 33 will then exert a force on the connecting rod 323, causing the connecting rod 323 to slide within the inner cavity of the outer shell 321. Water filling the inner cavity of the partition 322 will flow from one side of the partition 322 to the other, slowing down the movement of the connecting rod 323. Simultaneously, this will cause the spring 324 to contract. As the two sub-plates 33 move towards the support plate 31, the sides of the mattress will enter the connecting frames 26. Inside the cavity, the electric push rod 28 is operated, and its piston rod pushes the pressure plate 27 to slide within the cavity of the connecting frame 26. The pressure plate 27 then presses down on both sides of the mattress, clamping the mattress material and preventing it from falling during transport. Next, the controller controls the electric push rod 144, whose piston rod pushes the slide plate 145 upwards, which in turn moves the guide rod 11 and the threaded rod 12 upwards together, thus... The entire clamping assembly 2 is raised, which in turn raises the mattress material it is holding. Then, through the cooperation of motor 15 and threaded rod 12, the connecting plate 13, which is threadedly connected to threaded rod 12, moves, causing the entire clamping assembly 2 to move towards the support platform assembly 4. This moves the clamping assembly 2 above the rubber plate 43. Then, through electric push rod 144, the sliding plate 145 slides downwards, thereby causing guide rod 11, motor 22, and the entire clamping assembly 2 to move downwards. The device moves downward, allowing the mattress material held by the clamping component 2 to be placed on the upper end of the rubber plate 43. Then, the electric push rod 28 drives the pressure plate 27 to reset, releasing the pressure on the mattress material. Next, the motor 22 is run, and the T-block 25 is reset by the cooperation of the motor 22 and the bidirectional lead screw 23. This causes the two connecting frames 26 to move away from the mattress material. Finally, the device is reset, moving the clamping component 2 directly above the placement component 3, and then waiting to clamp and transport new material.

[0052] When the stacking angle of the materials needs to be adjusted, the controller controls the operation of the electric push rod 48. The piston rod of the electric push rod 48 pushes the rack 47 to move, and then the rack 47 meshes with the adjacent gear 46, which drives the rotating shaft 44 to rotate. Since the upper end of the rotating shaft 44 is fixedly connected to the lower end of the rubber plate 43, the rotating shaft 44 can drive the rubber plate 43 to rotate. During rotation, in order to avoid displacement or rotation of the mattress material placed on the rubber plate 43, the pushing process of the electric push rod 48 will be slow to avoid adverse effects from the speed.

[0053] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
