Description

A mattress manufacturing method Technical Field

[0001] This invention relates to the field of mattress machinery technology, and more specifically to a mattress manufacturing method. Background Technology

[0002] Spring mattresses are a common type of furniture.

[0003] Current spring mattress production typically involves gluing multiple spring strips together. However, when these glued, bagged springs are disassembled and recycled, the glue residue pollutes the environment. This contradicts current green and environmentally friendly ecological principles.

[0004] To align with green production principles, a welding mechanism exists that uses a retractable top plate and a welding mechanism that welds to it. The welding mechanism pushes a string of bagged springs towards the top plate, where they are then welded in a staggered fashion. However, this structure requires the top plate to be raised each time a string of bagged springs needs to be inserted. The welding mechanism then pushes the springs in, and the top plate is then inserted between two springs to complete the welding. This process is prone to misalignment during insertion, easily leading to incorrect top plate insertion and resulting in defective products, hindering continuous production. Furthermore, the welding mechanism can only push the springs through the gaps in the non-woven fabric, which can cause misalignment and prevent the springs from fitting between adjacent top plates, leading to downtime and further hindering continuous production. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention aims to provide a mattress production method that can avoid misalignment during insertion.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mattress manufacturing method includes the following steps:

[0008] S1: The Nth pocket spring string of a mattress is ready to be pushed. At this time, one set of top plates is located in the pushing area and the other set of top plates is located in the welding area. The two sets of top plates are staggered.

[0009] S2: The bag spring string is pushed towards the top plate in the pushing area, so that the top plate in the pushing area presses against the interval of the bag spring string.

[0010] S3: The welding mechanism of the top plate at the corresponding welding area extends so that the welding mechanism cooperates with the top plate at the welding area to weld the spaced portions of two adjacent bag spring strings together, and then the welding mechanism is reset.

[0011] S4: A set of top plates located in the pushing area moves synchronously with the bag spring string towards the welding area until it enters the welding area, while another set of top plates moves out of position until it reaches the pushing area, waiting for the next bag spring string to enter.

[0012] S5: Repeat S1~S4 until the welding of a mattress is completed.

[0013] Furthermore, the welding mechanism of the top plate at the corresponding welding area extends to cooperate with the top plate at the welding area to weld the spacer portions of two adjacent bag spring strings together, including:

[0014] S41: The welding mechanism corresponds one-to-one with the two sets of top plates, and the welding mechanism of the top plate at the corresponding welding area extends out;

[0015] S42: The welding mechanism works with the top plate in the welding area to weld the gaps between two adjacent bag spring strings together.

[0016] Furthermore, the welding mechanism of the top plate at the corresponding welding area extends to cooperate with the top plate at the welding area to weld the spacer portions of two adjacent bag spring strings together, including:

[0017] S401: The welding mechanism corresponds to a set of top plates, and the overall displacement of the welding mechanism makes the welding mechanism correspond to the top plate at the welding area, and the welding mechanism extends out;

[0018] S402: The welding mechanism works with the top plate in the welding area to weld the gaps between two adjacent bag spring strings together.

[0019] Furthermore, the other set of top plates is misaligned until it is displaced to the welding area. Specifically, the other set of top plates is raised away from the bag spring string, then the set of top plates is displaced above the pushing area, and finally the set of top plates is lowered into the pushing area.

[0020] The present invention also provides a mattress manufacturing machine that can separate the pushing action from the welding action, avoiding the misalignment of the spring during the pushing action caused by using a welding mechanism that pushes and welds at the same time.

[0021] To achieve the above objectives, the present invention adopts the following technical solution:

[0022] Mattress manufacturing machinery includes a top plate, a welding mechanism, and a pushing mechanism. Two sets of top plates are staggered and arranged laterally. The pushing mechanism can push the springs between two adjacent top plates longitudinally. The two sets of top plates can move longitudinally and vertically respectively. The welding mechanism is arranged laterally and can move independently or synchronously along the longitudinal direction. The welding mechanism cooperates with the top plate to achieve welding.

[0023] Furthermore, it also includes a mounting frame, on which several cantilever arms are provided. The two sets of top plates are respectively mounted on the cantilever arms of the two mounting frames, and the cantilever arms of the two mounting frames are staggered.

[0024] Furthermore, the welding mechanism corresponds one-to-one with the two sets of staggered top plates, and the welding mechanism can be displaced along the arrangement direction of the top plates.

[0025] Furthermore, the welding mechanism is respectively associated with the two sets of top plates at intervals, and the number of welding mechanisms is greater than the number of top plates in each set.

[0026] Furthermore, the ejection mechanism includes push plates, two push plates for pushing the two ends of the spring, and the welding mechanism is located between the two push plates.

[0027] Furthermore, it also includes a mounting frame, on which several cantilever arms are provided. The two sets of top plates are respectively mounted on the cantilever arms of the two mounting frames, and the cantilever arms of the two mounting frames are staggered.

[0028] The present invention has the following beneficial effects:

[0029] This invention provides a mattress production method that uses two sets of staggered top plates, which are alternately displaced and welded together. This ensures that during each push-in, one set of top plates waits for the pocket springs to be pushed in and positioned, eliminating the need for top plates to be inserted through gaps. This effectively avoids misalignment during insertion, preventing the generation of defective products. The invention also provides mattress production machinery that not only implements the above-mentioned mattress production method but also separates the pushing and welding actions by incorporating a pushing mechanism. This avoids the situation where a welding mechanism pushes out and welds simultaneously, causing spring misalignment during pushing out, and facilitates continuous production.

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0040] As shown in Figures 1-7, the present invention provides a mattress manufacturing method, which includes the following steps:

[0041] S1: The Nth pocket spring string of a mattress is ready to be pushed. At this time, one set of top plates is located in the pushing area and the other set of top plates is located in the welding area. The two sets of top plates are staggered.

[0042] S2: The bag spring string is pushed towards the top plate in the pushing area, so that the top plate in the pushing area presses against the interval of the bag spring string.

[0043] S3: The welding mechanism of the top plate at the corresponding welding area extends so that the welding mechanism cooperates with the top plate at the welding area to weld the spaced portions of two adjacent bag spring strings together, and then the welding mechanism is reset.

[0044] S4: A set of top plates located in the pushing area moves synchronously with the bag spring string towards the welding area until it enters the welding area, while another set of top plates moves out of position until it reaches the pushing area, waiting for the next bag spring string to enter.

[0045] S5: Repeat S1~S4 until the welding of a mattress is completed.

[0046] As shown in the figure, there is a bag spring string 1, a spacer 2 between two adjacent bag springs, a top plate 3, a pushing area 4, and a welding area 5.

[0047] The advantages of this invention are: by setting the steps of alternating displacement of the top plate 3 and synchronous displacement of the top plate 3 and the bag spring, the original solution's step of inserting the top plate 3 between the two bag spring strings 1 and cooperating with the welding mechanism for welding is replaced. This ensures that each time the material is pushed, a set of top plates 3 waits for the bag spring strings 1 to be pushed in and positioned, without the need for the top plate 3 to be inserted from the gap, effectively avoiding the generation of waste products due to misaligned insertion positions.

[0048] Furthermore, the welding mechanism of the top plate at the corresponding welding area extends to cooperate with the top plate at the welding area to weld the spacer portions of two adjacent bag spring strings together, including:

[0049] S31: The welding mechanism corresponds one-to-one with the two sets of top plates, and the welding mechanism of the top plate at the corresponding welding area extends out;

[0050] S32: The welding mechanism works with the top plate in the welding area to weld the gaps between two adjacent bag spring strings together.

[0051] Furthermore, the welding mechanism of the top plate at the corresponding welding area extends to cooperate with the top plate at the welding area to weld the spacer portions of two adjacent bag spring strings together, including:

[0052] S301: The welding mechanism corresponds to a set of top plates. The overall displacement of the welding mechanism makes the welding mechanism correspond to the top plate at the welding area, and the welding mechanism extends out.

[0053] S302: The welding mechanism cooperates with the top plate in the welding area to weld the gaps between two adjacent bag spring strings together.

[0054] Furthermore, the other set of top plates is misaligned until it is displaced to the welding area. Specifically, the other set of top plates is raised away from the bag spring string, then the set of top plates is displaced above the pushing area, and finally the set of top plates is lowered into the pushing area.

[0055] Figures 8 and 9 show the mattress production machinery proposed in this invention, including a top plate 3, a welding mechanism 6, and a pushing mechanism 7. Two sets of top plates 3 are staggered and arranged laterally. The pushing mechanism 7 can push longitudinally to push the pocket springs into the space between two adjacent top plates 3. The two sets of top plates 3 can move longitudinally and vertically respectively. The welding mechanism 6 is arranged laterally and can move independently or synchronously along the longitudinal direction. The welding mechanism 6 cooperates with the top plates 3 to achieve welding.

[0056] In use, the spring string is fed in, and the ejection mechanism 7 pushes the bagged spring string towards the top plate 3 so that the spring enters between two adjacent top plates 3. Then, the welding mechanism 6 extends until the gap between the welding mechanism 6 and the top plate 3 is filled with non-woven fabric. Then, the welding mechanism 6 and the top plate 3 cooperate to start welding. At this time, the ejection mechanism 7 resets. After welding is completed, the welding mechanism 6 resets, one of the top plates 3 is raised away from the bagged spring string, and then the top plate 3 is moved to the next bagged spring string's push-in position. Then, the top plate 3 is lowered to its original height, and the ejection mechanism 7 pushes the bagged spring string. When the bagged spring string reaches the position of the set of top plates 3, the top plate 3 and the ejection mechanism 7 move synchronously until the welding position. Then, the welding mechanism 6 extends and cooperates with the top plate 3 to weld two adjacent bagged spring strings together. The ejection mechanism 7 resets, and after welding is completed, the welding mechanism 6 resets. Then, the other set of top plates 3 is raised, and so on, so that several bagged spring strings are welded at intervals to form a bed net.

[0057] Furthermore, it also includes a mounting frame 31, on which a plurality of cantilever arms 32 are provided. The two sets of top plates 3 are respectively mounted on the cantilever arms 32 on the two mounting frames 31, and the cantilever arms 32 on the two mounting frames 31 are staggered.

[0058] By setting up the mounting bracket 31 and the staggered cantilever 32, the top plate 3 is always within the interval range of the staggered cantilever 32 during displacement, thereby facilitating the displacement of the top plate 3 and preventing the displacement of the two sets of top plates 3 from obstructing each other.

[0059] Furthermore, the welding mechanism 6 corresponds one-to-one with the two sets of staggered top plates 3, and the welding mechanism 6 can be displaced along the arrangement direction of the top plates 3.

[0060] In one embodiment of the present invention, more specifically, the welding mechanism 6 corresponds one-to-one with a set of top plates 3. After each welding is completed, the welding mechanism 6 needs to be displaced along the arrangement direction of the top plates 3 so that the welding mechanism 6 corresponds to another set of top plates 2, thereby reducing the number of welding mechanisms 6 and reducing the cost of the machine.

[0061] Furthermore, the welding mechanism 6 is respectively spaced and corresponds to the two sets of top plates 3, and the number of welding mechanisms 6 is greater than the number of top plates 3 in each set.

[0062] More specifically, the welding mechanism 6 is spaced apart from each set of top plates 3. After each welding is completed, the welding mechanism 6 does not need to be displaced or repositioned. When welding is needed each time, the corresponding welding mechanism 6 only needs to be extended. The welding mechanism 6 does not need to be displaced or repositioned, which is conducive to standardized production and improves production efficiency.

[0063] Furthermore, the ejection mechanism 7 includes two push plates for pushing the two ends of the bagged spring string, and the welding mechanism 6 is located between the two push plates.

[0064] More specifically, by setting up upper and lower push plates, it is convenient to push out the bagged spring string. At the same time, the welding mechanism 6 is located between the two push plates, which can effectively separate the pushing action and the welding action, and the two actions will not affect each other.

[0065] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this invention.
