Mattress bonding method and mattress bonding production line

Abstract

This invention discloses a mattress bonding method where the mattress core is conveyed sideways after molding, and reinforcing spring strips are bonded from the front and rear of the core's conveying direction. The entire process requires only forward conveying and waiting for bonding, eliminating the need for side clamping and reverse conveying. This avoids the impact of side clamping on the core and the disruption to continuous production caused by reciprocating conveying. The invention also discloses a mattress bonding production line. By setting a misalignment mechanism, the second pushing mechanism can avoid the core's conveying position, thus preventing the second pushing mechanism from affecting the entire production process and facilitating continuous production. Finally, a first adhesive spraying mechanism for bonding the core and a second adhesive spraying mechanism for bonding soft materials are set up, with the first and second spraying mechanisms perpendicular to each other. This allows for the direct production of mattresses where the soft material's adhesive spraying direction is perpendicular to the core's adhesive spraying direction.

Description

Technical Field

[0001] This invention relates to the field of mattress technology, specifically to a mattress bonding method and a mattress bonding production line. Background Technology

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

[0003] In the production of pocket spring mattresses, the mattress mesh is made up of multiple pocket springs arranged and glued together. Because the pocket springs are supported by the springs themselves, their shape is unstable and prone to deformation. Therefore, it is often necessary to attach a wire frame or glue a ring of rigid material around the mattress mesh to maintain its shape stability. Currently, both of these methods are done manually, resulting in low automation and low production efficiency.

[0004] To achieve automated production, there is a device for pasting shaping material around the perimeter of a bed net and a mattress manufacturing equipment (CN 218256868 U). It is equipped with a bonding mechanism and a rotating mechanism. The mattress is conveyed by a conveyor belt, and then the bonding mechanism bonds the edges of the mattress on both sides. Then the rotating mechanism rotates the bed net or the bonding mechanism so that the bonding mechanism can bond the edges of the other two sides of the bed net, thus realizing the bonding of the edges of a bed net.

[0005] However, the structural materials of this type of mattress are all glued from the sides. Each time it is glued, the mattress needs to be clamped from both sides. This method can easily affect the mattress core. Excessive pressure may even damage the mattress core, which is not conducive to production.

[0006] To address this issue, a mattress production line exists that uses the reciprocating motion of the mattress to bond the stiffened spring strips to both sides. However, this structure requires the mattress core to be transported in both the front and back directions, which is not conducive to continuous production.

[0007] Meanwhile, in the production process of pocket spring mattresses, a layer of soft material (usually non-woven fabric) is typically placed over the top and bottom ends of the core to ensure complete bonding. Generally, in existing mattresses, the non-woven fabric is bonded during the mattress bonding process; that is, when one pocket spring is bonded to another, the non-woven fabric is simultaneously bonded to the top and bottom ends of that pocket spring. This results in the adhesive strip between the core and the non-woven fabric being parallel to the pocket springs. Therefore, when separating the non-woven fabric from the core, some pocket springs can easily be pulled out along with the non-woven fabric because the direction of force is parallel to the adhesive direction of the pocket springs, hindering separation and reuse. Therefore, a mattress with the soft material sprayed with adhesive in a direction parallel to the direction of the pocket springs in the core is proposed. Existing machinery cannot directly produce mattresses with the soft material sprayed with adhesive in a direction perpendicular to the adhesive direction of the core. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention aims to provide a mattress bonding method and production machinery that eliminates the need for bonding from both sides and reciprocating conveying of the mattress core, while ensuring that the bonding direction of the soft material is perpendicular to the bonding direction of the pocket spring strips in the mattress core.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A mattress bonding method involves bonding a mattress core with at least one stiffened spring strip bonded to both the front and back ends and at least one pocketed spring strip bonded to the middle. The core is then conveyed with either the left or right side as the positive direction. During this conveying process, the positive side of the mattress core is bonded to the stiffened spring strip. Then, the stiffened spring strip is pushed towards the mattress core from the other side, causing it to bond to the other side of the mattress core. Simultaneously, during the bonding process, the top and / or bottom of the mattress core are bonded to a soft material.

[0011] Furthermore, the specific steps of this bonding method are as follows:

[0012] S1: After the stiffened spring strip and the bagged spring strip are fed sequentially from the first feeding mechanism, they are sprayed with glue by the first glue spraying mechanism. The first pushing mechanism pushes the stiffened spring strip and the bagged spring strip to the first platform to be bonded together. At the same time, S2 is carried out until a bed core with at least one stiffened spring strip bonded at both ends and at least one bagged spring strip bonded in the middle is formed, and then enters S3.

[0013] S2: At least one stiffened spring strip is fed sequentially from the second feeding mechanism. After being sprayed with glue by the second glue spraying mechanism, the second pushing mechanism pushes the stiffened spring strip sequentially to the second platform to wait for bonding. At the same time, soft material is continuously fed from the unwinding mechanism so that the soft material and the stiffened spring strip are bonded together.

[0014] S3: The bed core of the first platform is conveyed to the second platform from the side. When the bed core passes through the second feeding mechanism, the second glue spraying mechanism sprays glue. The bed core is bonded to the hardened spring strip waiting on the second platform from the side. At the same time, the bed core is bonded to the soft material and enters S4.

[0015] S4: The mattress core enters the second platform completely through the second feeding mechanism. The stiffened spring strips are fed from the second feeding mechanism in sequence. After being sprayed with glue by the second glue spraying mechanism, the second pushing mechanism pushes the stiffened spring strips into the second platform in sequence, so that the stiffened spring strips are bonded together with the mattress core and soft materials, thus completing the production of a mattress.

[0016] Furthermore, the method also includes a misalignment mechanism, so steps S2 and S4 are as follows:

[0017] S2: At least one hardened spring strip is fed sequentially from the second feeding mechanism. After being sprayed with glue by the second glue spraying mechanism, the second pushing mechanism pushes the hardened spring strip sequentially to the second platform to wait for bonding. At the same time, soft material is continuously fed from the unwinding mechanism so that the soft material is bonded to the hardened spring strip. Then the misalignment mechanism misaligns the position of the second pushing mechanism.

[0018] S4: The mattress core enters the second platform completely through the second feeding mechanism. The misalignment mechanism resets the position of the second pushing mechanism. The stiffened spring strips are fed from the second feeding mechanism in sequence. After being sprayed with glue by the second glue spraying mechanism, the second pushing mechanism pushes the stiffened spring strips into the second platform in sequence, so that the stiffened spring strips are bonded together with the mattress core and soft materials, thus completing the production of a mattress.

[0019] The present invention also provides a mattress bonding production line for implementing this production method, the specific solution of which is as follows:

[0020] A mattress bonding production line includes a first bonding mechanism and a second bonding mechanism, wherein the first bonding mechanism is provided;

[0021] The first bonding mechanism includes a first feeding mechanism, a first pushing mechanism, a first glue spraying mechanism, and a first platform. The stiffened spring strip and the bagged spring strip are fed sequentially from the first feeding mechanism. The first glue spraying mechanism is used to spray glue onto the stiffened spring strip and the bagged spring strip sequentially. The first pushing mechanism is used to push the stiffened spring strip and the bagged spring strip sequentially into the first platform to form a bed core with at least one stiffened spring strip bonded at both ends and at least one bagged spring strip bonded in the middle. The first platform is used to input the bed core into the second bonding mechanism with the side facing the second bonding mechanism.

[0022] The second bonding mechanism includes a second feeding mechanism, a second pushing mechanism, a second glue spraying mechanism, a misalignment mechanism, an unwinding mechanism, and a second platform. The stiffened spring strip is fed from the second feeding mechanism. The pushing mechanism is used to push the stiffened spring strip to the second platform. An unwinding mechanism for unwinding soft materials into the second platform is provided above and / or below the second platform. The second glue spraying mechanism is used to spray glue onto the stiffened spring strip, the bed core, and the soft materials, and the glue spraying direction of the second glue spraying mechanism is perpendicular to the glue spraying direction of the first glue spraying mechanism.

[0023] Furthermore, the conveying direction of the first platform is parallel to the conveying direction of the first feeding mechanism.

[0024] Furthermore, the second glue spraying mechanism includes a drive mechanism, a glue spraying head, and a telescopic rod. The drive mechanism is used to drive the glue spraying head to move back and forth along the conveying direction of the second feeding mechanism, and the telescopic rod is used to drive the glue spraying head to extend and retract up and down.

[0025] Furthermore, both the first platform and the second platform are clamping conveyor belts arranged vertically, and the conveying directions of the first platform and the second platform are parallel.

[0026] Furthermore, the misalignment mechanism is a cylinder.

[0027] Furthermore, the second bonding mechanism also includes a transition platform, which is located between the first platform and the first feeding mechanism, and the conveying direction of the transition platform is parallel to the conveying direction of the first platform.

[0028] Furthermore, both the first and second feeding mechanisms use clamping conveyor belts arranged vertically, and the conveying directions of the first and second feeding mechanisms are perpendicular.

[0029] The present invention has the following beneficial effects:

[0030] This invention discloses a mattress bonding method in which the mattress core is conveyed sideways after molding, and reinforcing spring strips are bonded from the front and rear of the core's conveying direction. The entire process requires only forward conveying and waiting for bonding, eliminating the need for side clamping and reverse conveying. This avoids the impact of side clamping on the core and the disruption to continuous production caused by reciprocating conveying. Simultaneously, during side reinforcing spring strip bonding, soft materials are bonded simultaneously on the top and / or bottom surfaces, facilitating rapid production. This invention also discloses a mattress bonding production line, which utilizes a first bonding mechanism and a second bonding mechanism... The mechanism works in a way that the bonding direction of the stiffened spring strips is consistent with the conveying direction of the mattress core, thus avoiding the need for the mattress core to be clamped and bonded from both sides or moved back and forth for conveying. Secondly, by setting up a staggered mechanism, the second pushing mechanism can avoid the conveying position of the mattress core, thus avoiding the impact of the second pushing mechanism on the entire production process and facilitating continuous production. Finally, a first glue spraying mechanism for bonding the mattress core and a second glue spraying mechanism for bonding the soft material are set up, with the first glue spraying mechanism perpendicular to the second glue spraying mechanism, so that a mattress with the glue spraying direction of the soft material perpendicular to the glue spraying direction of the mattress core can be produced directly.

[0048] 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.

[0049] like Figures 1-2 and Figures 12-17 The invention discloses a mattress bonding method. After bonding a mattress core with at least one stiffened spring strip bonded to both the front and back ends and at least one pocketed spring strip bonded to the middle, the mattress core is conveyed with either the left or right side as the positive direction. During the conveying process, the positive side of the mattress core is bonded to the stiffened spring strip. Then, the stiffened spring strip is pushed towards the mattress core from the other side so that the stiffened spring strip is bonded to the other side of the mattress core. At the same time, during the bonding process, the top and / or bottom of the mattress core are bonded to the soft material.

[0050] It should be noted that the soft material is non-woven fabric.

[0051] The advantages of the mattress bonding method of this invention are as follows: After the mattress core is formed, it is conveyed sideways in a forward direction. The reinforcing spring strips are bonded from the front and rear of the mattress core conveying direction. The entire process only requires forward conveying and waiting for bonding. There is no need to clamp and bond from both sides or convey it in reverse. This avoids the impact of clamping and bonding from both sides on the mattress core and also avoids the impact of reciprocating conveying of the mattress core on continuous production. At the same time, when the reinforcing spring strips are bonded from the side, the soft material is bonded simultaneously on the top and / or bottom surfaces, which is conducive to rapid production.

[0052] To further illustrate the specific advantages of this invention, the specific bonding process of this invention will be further explained, such as... Figure 1 The diagram illustrates the specific steps of a mattress bonding method according to the present invention, as follows: Figures 12-17 The diagram shows a flowchart of the product manufactured using this method. Figure 1 As shown and combined Figures 12-17 As shown, the specific steps include:

[0053] S1: After the stiffened spring strip and the bagged spring strip are sequentially fed from the first feeding mechanism 11, they are sprayed with glue by the first glue spraying mechanism 13, and then the first pushing mechanism 12 sequentially pushes the stiffened spring strip and the bagged spring strip to the first platform 14 for bonding together (e.g., Figure 12 As shown), simultaneously perform S2 until a bed core is formed with at least one stiffened spring strip bonded to both ends and at least one pocketed spring strip bonded to the middle (as shown). Figure 13 As shown), enter S3;

[0054] S2: At least one stiffened spring strip is fed sequentially from the second feeding mechanism 21. After being sprayed with glue by the second glue spraying mechanism 23, the second pushing mechanism 22 pushes the stiffened spring strip sequentially to the second platform 24 to wait for bonding. At the same time, soft material is continuously fed from the unwinding mechanism 26 so that the soft material is bonded to the stiffened spring strip.

[0055] S3: The bed core on the first platform 14 is conveyed from the side to the second platform 24. When the bed core passes the second feeding mechanism 21, the second glue spraying mechanism 23 sprays glue, and one side of the bed core is bonded to the stiffened spring strip waiting on the second platform 24 (e.g., Figure 14 (As shown), at the same time, the bed core is bonded together with the soft material and enters S4;

[0056] S4: The bed core completely enters the second platform 24 through the second feeding mechanism 21. The stiffened spring strips are fed sequentially from the second feeding mechanism 21, and after being sprayed with glue by the second glue spraying mechanism 23, the second pushing mechanism 22 pushes the stiffened spring strips sequentially into the second platform 24 (e.g., Figure 15 (As shown) This allows the stiffened spring bars to bond together with the bed core and soft materials (such as...). Figure 16 and Figure 17 As shown in the figure, this completes the production of a mattress.

[0057] Furthermore, the method also includes a misalignment mechanism 25, so steps S2 and S4 are as follows:

[0058] S2: At least one stiffened spring strip is fed sequentially from the second feeding mechanism 21. After being sprayed with glue by the second glue spraying mechanism 23, the second pushing mechanism 22 pushes the stiffened spring strip sequentially to the second platform 24 to wait for bonding. At the same time, soft material is continuously fed from the unwinding mechanism 26 so that the soft material is bonded to the stiffened spring strip. Then the misalignment mechanism 25 misaligns the position of the second pushing mechanism 22.

[0059] S4: The mattress core is completely fed into the second platform 24 through the second feeding mechanism 21. The misalignment mechanism 25 resets the position of the second pushing mechanism 22. The stiffened spring strips are fed from the second feeding mechanism 21 in sequence. After being sprayed with glue by the second glue spraying mechanism 23, the second pushing mechanism 22 pushes the stiffened spring strips into the second platform 24 in sequence, so that the stiffened spring strips are bonded together with the mattress core and soft materials, thus completing the production of a mattress.

[0060] More specifically, by setting up the misalignment mechanism 25, the step of driving the second pushing mechanism 22 to misalign and reset is added, thereby avoiding the second pushing mechanism 22 from obstructing the bed core during the conveying process, thus ensuring the smooth flow of this bonding method and further improving the smoothness of this method.

[0061] The present invention also provides a mattress bonding production line for implementing this production method, the specific solution of which is as follows:

[0062] like Figures 3-11 As shown, the mattress bonding production line includes a first bonding mechanism 1 and a second bonding mechanism 2, wherein the first bonding mechanism 1 is provided;

[0063] The first bonding mechanism 1 includes a first feeding mechanism 11, a first pushing mechanism, a first glue spraying mechanism 13, and a first platform 14. The stiffened spring strip and the bagged spring strip are fed sequentially from the first feeding mechanism 11. The first glue spraying mechanism 13 is used to spray glue onto the stiffened spring strip and the bagged spring strip sequentially. The first pushing mechanism is used to push the stiffened spring strip and the bagged spring strip sequentially into the first platform 14 to form a bed core with at least one stiffened spring strip bonded at both ends and at least one bagged spring strip bonded in the middle. The first platform 14 is used to input the bed core into the second bonding mechanism 2 with the side of the bed core facing the second bonding mechanism 2.

[0064] The second bonding mechanism 2 includes a second feeding mechanism 21, a second pushing mechanism, a second glue spraying mechanism 23, a misalignment mechanism 25, an unwinding mechanism 26, and a second platform 24. The stiffened spring strip is fed from the second feeding mechanism 21. The pushing mechanism is used to push the stiffened spring strip to the second platform 24. An unwinding mechanism 26 for unwinding soft materials into the second platform 24 is provided above and / or below the second platform 24. The second glue spraying mechanism 23 is used to spray glue on the stiffened spring strip, the bed core, and the soft materials. The glue spraying direction of the second glue spraying mechanism 23 is perpendicular to the glue spraying direction of the first glue spraying mechanism 13.

[0065] It should be noted that the first pushing mechanism 12 and the second pushing mechanism 22 have similar structures, including a push plate and a power source for driving the push plate to move back and forth. The power source only needs to be able to drive the push plate to move back and forth. The power source is preferably a cylinder.

[0066] More specifically, when this production line is in use, the first hardened spring strip is first fed into the first feeding mechanism 11, and then the first pushing mechanism 12 pushes the hardened spring strip into the first platform 14 to wait for bonding. Then the second hardened spring strip or the first bagged spring strip is fed into the first feeding mechanism 11, the first glue spraying mechanism 13 sprays glue, and then the first pushing mechanism 12 pushes the second hardened spring strip or the first bagged spring strip to the first platform 14 to bond with the first hardened spring strip. This process is repeated until the first pushing mechanism 12 pushes the last hardened spring strip to the first platform 14 to bond it into a bed core with at least one hardened spring strip bonded at both ends and at least one bagged spring strip bonded in the middle. At this time, the hardened spring strip preparation process on the second bonding mechanism 2 is carried out simultaneously.

[0067] The preparation process for the hardened spring strip on the second bonding mechanism 2 is as follows: The first hardened spring strip is input from the second feeding mechanism 21, the second glue spraying mechanism 23 sprays glue, the second pushing mechanism 22 pushes the first hardened spring strip into the second platform 24, and at the same time the unwinding mechanism 26 outputs soft material so that the first hardened spring strip and the soft material are bonded together on the second platform 24. Then the second hardened spring strip is input from the second feeding mechanism 21, the second glue spraying mechanism 23 sprays glue, the second pushing mechanism 22 pushes the second hardened spring strip into the second platform 24 so that the second hardened spring strip, the first hardened spring strip and the soft material are bonded together on the second platform 24. This process is repeated until the required hardened spring strips are bonded together, and then the second platform 24 waits to be bonded to the bed core. Then the misalignment mechanism 25 drives the second pushing mechanism 22 to shift away from the bed core.

[0068] The bed core is conveyed from the first platform 14 to the second platform 24 from the side. When the bed core passes the second feeding mechanism 21, the glue spraying mechanism sprays glue on the bed core, the stiffened spring strip and the soft material. Then the bed core is fed into the second platform 24 and bonded together with the stiffened spring strip and the soft material. Then the bed core continues to be fed into the second platform 24. Every time it passes the spacing of the springs in the bagged spring strip, the glue spraying mechanism sprays glue on the bed core and / or the soft material, so that the soft material is bonded to the top and / or bottom surface of the bed core. This is repeated until the bed core has completely passed through the second feeding mechanism 21.

[0069] After the mattress core has completely passed through the second feeding mechanism 21, the stiffened spring strip is input from the second feeding mechanism 21. At the same time, the misalignment mechanism 25 drives the second pushing mechanism 22 to reset, the second glue spraying mechanism 23 sprays glue, and the second pushing mechanism 22 pushes the stiffened spring strip into the second platform 24 to bond it together with the mattress core and soft material. Then the next stiffened spring strip is input from the second feeding mechanism 21 and waits to be pushed and bonded. This process is repeated until the bonding work of a mattress is completed.

[0070] The repeated use of the above process enables the mattress bonding production line of the present invention to continuously produce bonded mattresses.

[0071] The advantages of the mattress bonding production line of the present invention are as follows: 1. By cooperating with the first bonding mechanism 1 and the second bonding mechanism 2, the bonding direction of the stiffened spring strip is consistent with the conveying direction of the mattress core, thereby avoiding the problem that the mattress core needs to be clamped and bonded from both sides or moved back and forth for conveying; 2. By setting the misalignment mechanism 25, the second pushing mechanism 22 can avoid the conveying position of the mattress core, thereby avoiding the impact of the second pushing mechanism 22 on the entire production process and facilitating continuous production; 3. By setting a first glue spraying mechanism for bonding the mattress core and a second glue spraying mechanism for bonding the soft material, the first glue spraying mechanism and the second glue spraying mechanism are perpendicular to each other, thereby enabling the direct production of mattresses in which the glue spraying direction of the soft material is perpendicular to the glue spraying direction of the mattress core.

[0072] Furthermore, the conveying direction of the first platform 14 is parallel to the conveying direction of the first feeding mechanism 11.

[0073] More specifically, the conveying direction of the first platform 14 is parallel to the conveying direction of the first feeding mechanism 11, so that the bed core can be directly conveyed to the second platform 24 after it is bonded on the first platform 14.

[0074] Furthermore, the second glue spraying mechanism 23 includes a drive mechanism 231, a glue spraying head 232, and a telescopic rod 233. The drive mechanism 231 is used to drive the glue spraying head 232 to move back and forth along the conveying direction of the second feeding mechanism 21, and the telescopic rod 233 is used to drive the glue spraying head 232 to extend and retract up and down.

[0075] More specifically, by setting the telescopic rod 233, when only adhesive spraying is needed to bond the soft material and the bed core, the telescopic rod 233 can drive the spray head 232 to extend and retract, thereby avoiding the spray head 232 from affecting the bed core when the bed core is transported into the second platform 24.

[0076] like Figure 10 The diagram shows one embodiment of the second adhesive spraying mechanism 23 of the present invention. In this embodiment, a set of drive mechanisms 231 and adhesive spraying heads 232 are provided at both the upper and lower ends. Additionally, a set of adhesive spraying heads 232 connected to the telescopic rod 233 is also provided at the upper adhesive spraying head 232. This embodiment is mainly for cases where both the upper and lower ends of the bed core require the bonding of soft materials. In this case, the lower adhesive spraying head 232 sprays adhesive onto the lower soft material, and the upper adhesive spraying head 232 sprays adhesive onto the upper soft material. The adhesive spraying head 232 connected to the telescopic rod 233 is used to spray adhesive onto the stiffened spring strips and the sides of the bed core.

[0077] Furthermore, both the first platform 14 and the second platform 24 are clamping conveyor belts arranged vertically, and the conveying directions of the first platform 14 and the second platform 24 are parallel.

[0078] The first platform 14 and the second platform 24 are parallel in the conveying direction, so that when the bed core is input from the first platform 14 to the second platform 24, the side of the bed core is directly facing the hardened spring strip located on the second platform 24, thereby enabling the bed core to directly adhere to the hardened spring strip during the input process to the second platform 24, thereby improving the adhesion efficiency.

[0079] Furthermore, the misalignment mechanism 25 is a cylinder.

[0080] Furthermore, the misalignment mechanism 25 is a cylinder, and in Figure 3 In this embodiment, the misalignment mechanism 25 drives the second pushing mechanism 22 to misalign in the front-to-back direction. Figure 8 and Figure 9 In this embodiment, the second pushing mechanism 22 is mounted on the second feeding mechanism 21, and the misalignment mechanism 25 drives the second pushing mechanism 22 and the second feeding mechanism 21 to move up and down synchronously.

[0081] Furthermore, the second bonding mechanism 2 also includes a transition platform 27, which is disposed between the first platform 14 and the first feeding mechanism 11, and the conveying direction of the transition platform 27 is parallel to the conveying direction of the first platform 14.

[0082] More specifically, a transition platform 27 is provided between the first platform 14 and the second platform 24, so that the mattress core can enter the transition platform 27 to wait for bonding after bonding is completed, so as not to affect the bonding of the next mattress core, which is conducive to the continuous production of the mattress bonding production line of the present invention.

[0083] It needs to be further explained that:

[0084] like Figures 3-4 The diagram illustrates one embodiment of the present invention. In this embodiment, the misalignment mechanism 25 is a cantilever connected to an external power source. A second pushing mechanism 22 is mounted on the second feeding mechanism 21, which is mounted on the cantilever. The external power source drives the cantilever to rotate, causing the second pushing mechanism 22 and the second feeding mechanism 21 to move synchronously. When the cantilever rotates and rises, the second pushing mechanism 22 and the first feeding mechanism 21 move synchronously to the inlet end of the second platform 24, and the second pushing mechanism 22 pushes the stiffened spring strip on the second feeding mechanism 21 toward the second platform 24. When the cantilever rotates and falls, the second pushing mechanism 22 and the first feeding mechanism 21 move synchronously below the transition platform 27.

[0085] It should be noted that, as Figures 3-4 In the illustrated embodiment, the transition platform 27 can be displaced in the left-right direction. Specifically, when the second pushing mechanism 22 and the second feeding mechanism 21 need to be rotated and raised to the feeding end of the second platform 24, the transition platform 27 moves to the left away from the second platform 24 and closer to the first platform 14, thereby facilitating the displacement of the second pushing mechanism 22 and the second feeding mechanism 21. At this time, the first platform 14 conveys the already bonded bed core to the transition platform 27. When the bed core needs to be conveyed to the second platform 24, the second pushing mechanism 22 and the second feeding mechanism 21 rotate and descend below the transition platform 27. Then, the transition platform 27 moves to the right and closer to the second platform 24. Then, the first platform 14 inputs the bed core into the second platform 24.

[0086] It should be noted that, as Figures 3-4In the illustrated embodiment, if the transition platform 27 is not provided, the first platform 14 can be displaced in the left and right directions. Specifically, when the second pushing mechanism 22 and the second feeding mechanism 21 need to be rotated and raised to the feeding end of the second platform 24, the first platform 14 is displaced to the left away from the second platform 24, thereby facilitating the displacement of the second pushing mechanism 22 and the second feeding mechanism 21. When the bed core needs to be conveyed to the second platform 24, the second pushing mechanism 22 and the second feeding mechanism 21 are rotated and lowered below the first platform 14, and then the first platform 14 is displaced to the right and closer to the second platform 24, and then the first platform 14 inputs the bed core into the second platform 24.

[0087] like Figures 5-6 The illustration shows one embodiment of the present invention. In this embodiment, the misalignment mechanism is a cylinder that drives the second pushing mechanism to move back and forth. When the piston rod of the misalignment mechanism extends, the second pushing mechanism moves to the second feeding mechanism to push the stiffened spring strip on the second feeding mechanism to the second platform.

[0088] like Figures 7-9 The illustration shows one embodiment of the present invention. In this embodiment, the second pushing mechanism is installed on the side of the second driving mechanism, and the misalignment mechanism is a cylinder that drives the second pushing mechanism and the second feeding mechanism to rise and fall synchronously. When the misalignment mechanism drives the second pushing mechanism and the second feeding mechanism to rise synchronously, the second pushing mechanism 22 and the second feeding mechanism 21 are displaced to the input end of the second platform. At this time, the side of the second feeding mechanism 21 is used to push the stiffened spring strip on the second pushing mechanism 22 toward the second platform. When the misalignment mechanism drives the second pushing mechanism and the second feeding mechanism to fall synchronously, the second pushing mechanism 22 and the second feeding mechanism fall synchronously, and at this time, the highest point of the second pushing mechanism 22 and the second feeding mechanism is lower than or equal to the conveying surface of the first platform, the second platform, and the transition platform.

[0089] It should be noted that, as Figures 7-9 In the embodiment shown, the transition platform 27 uses a combined conveyor belt, so that the overall structure of the transition platform 27 is long at both ends and short in the middle, which facilitates the displacement of the second pushing mechanism 22 without affecting the conveying of the bed core by the transition platform 27.

[0090] It should be noted that, as Figures 7-9 In the embodiment shown, if the transition platform 27 is not provided, the first platform is a combined conveyor belt, so that the first platform has a structure that is long at both ends and short in the middle, which facilitates the displacement of the second pushing mechanism 22 without affecting the conveying of the bed core by the first platform.

[0091] Furthermore, both the first feeding mechanism 11 and the second feeding mechanism 21 are equipped with clamping conveyor belts arranged vertically, and the conveying directions of the first feeding mechanism 11 and the second feeding mechanism 21 are perpendicular.

[0092] More specifically, the first feeding mechanism 11 and the second feeding mechanism 21 are equipped with clamping conveyor belts, thereby ensuring that the positions of the first feeding mechanism 11 and the second feeding mechanism 21 are controllable when the bagged spring strips or hardened spring strips are input, which is conducive to quickly conveying the bagged spring strips or hardened spring strips into place and facilitating rapid bonding.

[0093] like Figures 12-17 The diagram shows a production process flow chart for the mattress produced by this invention.

[0094] In the figure, the standards are as follows: pocket spring strip 32, stiffened spring strip including first stiffened strip 31 and second stiffened strip 33, transverse adhesive tape 35 in the bed core, and longitudinal adhesive tape 34 between the bed core and the soft material.

[0095] like Figures 12-13 As shown, the front and rear ends are first stiffening strips 31, and the middle part is at least one bagged spring strip 32 arranged in parallel and bonded together to form the bed core.

[0096] like Figure 14 As shown, the second stiffening strip 33 is located in front of the mattress conveying direction (which is also the side of the mattress, i.e., the right side of the mattress core shown in the figure), waiting for the mattress core to be conveyed forward and bonded.

[0097] like Figures 15-16 As shown, after the mattress is bonded to the second reinforcing strip 33 at the front of the conveying direction, the mattress core stops conveying. Then, another reinforcing strip is pushed forward from the rear of the mattress conveying direction (i.e., from left to right as shown in the figure), causing the reinforcing spring strip to bond to the other side of the mattress (i.e., the left side of the mattress core as shown in the figure), forming the mattress (i.e., Figure 16 ).

[0098] like Figure 17 As shown, the soft material is adhered to the mattress by spraying adhesive, so that the soft material and the mattress form a longitudinal adhesive strip 34 along the direction perpendicular to the pocket spring strip in the top view, and the longitudinal adhesive strip 34 is perpendicular to the transverse adhesive strip 35, so that the longitudinal adhesive strip 34 and the transverse adhesive strip 35 form a cross grid.

[0099] It should be noted that in the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0100] 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.

Claims

1. A mattress bonding method, characterized in that: After bonding a bed core with at least one stiffened spring strip bonded to both ends and at least one bagged spring strip bonded to the middle, the bed core is conveyed with either the left or right side as the positive direction. During the conveying process, the positive side of the bed core is bonded to the stiffened spring strip. Then, the stiffened spring strip is pushed towards the bed core from the other side of the bed core so that the stiffened spring strip is bonded to the other side of the bed core. At the same time, during the bonding process, the top and / or bottom of the bed core are bonded to the soft material. The specific steps for this bonding method are as follows: S1: After the stiffened spring strip and the bagged spring strip are fed sequentially from the first feeding mechanism, they are sprayed with glue by the first glue spraying mechanism. The first pushing mechanism pushes the stiffened spring strip and the bagged spring strip to the first platform to be bonded together. At the same time, S2 is carried out until a bed core with at least one stiffened spring strip bonded at both ends and at least one bagged spring strip bonded in the middle is formed, and then enters S3. S2: At least one stiffened spring strip is fed sequentially from the second feeding mechanism. After being sprayed with glue by the second glue spraying mechanism, the second pushing mechanism pushes the stiffened spring strip sequentially to the second platform to wait for bonding. At the same time, soft material is continuously fed from the unwinding mechanism so that the soft material and the stiffened spring strip are bonded together. S3: The bed core of the first platform is conveyed to the second platform from the side. When the bed core passes through the second feeding mechanism, the second glue spraying mechanism sprays glue. The bed core is bonded to the hardened spring strip waiting on the second platform from the side. At the same time, the bed core is bonded to the soft material and enters S4. S4: The mattress core enters the second platform completely through the second feeding mechanism. The stiffened spring strips are fed from the second feeding mechanism in sequence. After being sprayed with glue by the second glue spraying mechanism, the second pushing mechanism pushes the stiffened spring strips into the second platform in sequence, so that the stiffened spring strips are bonded together with the mattress core and soft materials, thus completing the production of a mattress.

At the same time, soft material is continuously fed from the unwinding mechanism so that the soft material is bonded to the hardened spring strip. Then the misalignment mechanism misaligns the position of the second pushing mechanism. S4: The mattress core enters the second platform completely through the second feeding mechanism. The misalignment mechanism resets the position of the second pushing mechanism. The stiffened spring strips are fed from the second feeding mechanism in sequence. After being sprayed with glue by the second glue spraying mechanism, the second pushing mechanism pushes the stiffened spring strips into the second platform in sequence, so that the stiffened spring strips are bonded together with the mattress core and soft materials, thus completing the production of a mattress.
