Description

Technical Field

[0001] The present application relates to the technical field of spring gasket core production, and in particular to a spring gasket core assembly device and a spring gasket core. Background Art

[0002] The spring core of mattresses and sofa cushions is composed of multiple pocket springs. During the production process, the continuous pocket springs need to be divided into spring strings of designed length, and then the multiple rows of spring strings are bonded together with adhesive to form a spring core.

[0003] For spring cores of mattresses or sofa cushions with curved surfaces, pocket springs of different heights need to be bonded and assembled. Currently, spring core assembly equipment mostly uses upper and lower conveyor belts to clamp spring pads for gluing and conveying. This is suitable for bonding spring pads with flat tops and bottoms, but cannot be used to bond pocket springs of different heights. In addition, during the bonding process, there is a lack of limit on the side of the pocket springs, resulting in the spring strings of two adjacent rows of pocket springs not having front and rear pressure to make them close together during bonding, which easily leads to loose bonding of the spring strings.

[0082] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0083] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0084] For ease of understanding, in the following text, the conveying direction of the spring string on the working platform is set as the longitudinal direction, and the direction along the horizontal plane perpendicular to the longitudinal direction is set as the transverse direction.

[0085] Reference Figure 1 and Figure 2 , this embodiment provides a spring gasket core assembly device, including a frame 100, a working platform 200, a limiting mechanism 300, a glue spraying mechanism 400 and a feeding mechanism 500. Among them, the working platform 200 is arranged on the frame 100, and is used to place a spring string. Multiple rows of spring strings can be placed on the working platform 200 in sequence and combined into a spring gasket core. The feeding mechanism 500 is arranged at the feeding end of the working platform, and is used to provide a spring string to the working platform 200. The glue spraying mechanism 400 is arranged between the working platform 200 and the feeding mechanism 500, and is located on one side of the spring string, and is used to spray adhesive on the surface of the spring string so that the spring strings of two adjacent rows are bonded to each other through the adhesive. The limiting mechanism 300 includes a limiting member 310, which extends in the horizontal direction, is arranged above the working platform, and is movably connected to the frame 100, and can move on the surface of the working platform along the longitudinal spring string. Among them, one row of spring strings placed on the working platform 200 abuts against the limit member 310, and the limit member 310 adaptively moves in the longitudinal direction as the number of spring string combinations gradually increases, so as to make the two adjacent rows of spring strings adhere more firmly when the spring strings adhere, and can guide and position the spring strings.

[0086] The working platform 200 is used to carry the spring string. The working platform 200 only contacts the bottom of the spring string and has no restrictions on the top of the spring string, so that the spring string with an arc can be formed by using pocket springs of different heights and sizes to adhere to each other in a free state, and combined into a spring cushion core with a flat bottom and an arc-shaped top, thereby improving the production effect of the spring cushion core composed of pocket springs of different heights.

[0087] The limit piece 310 can be a limit plate that is perpendicular to the upper surface of the working platform 200 and is arranged above the working platform 200. When the spring gasket core is assembled, the first spring string placed on the working platform 200 rests against the surface of the limit piece 310, and the spring string is positioned by using the limit piece 310. When the working platform 200 drives the spring string to move at the discharge end, the limit piece 310 also moves synchronously. When other spring strings are placed on the working platform 200 and squeezed and bonded with the spring string in front, the limit piece 310 can limit the displacement of the spring string, thereby applying lateral force to the spring string, so that the two adjacent rows of spring strings are close together, thereby improving the tightness of each row of spring strings, and making the combined spring gasket core structure more solid and the size more accurate.

[0088] In some embodiments, the limit member 310 swings relative to the working platform 200 or moves in the vertical direction to change the distance between the limit member 310 and the working platform 200, so as to avoid the spring gasket core so that the spring gasket core can be output and unloaded.

[0089] For example, the stopper 310 may be Figure 3 As shown, the work platform 200 moves in the vertical direction. When the stopper 310 moves upward, the space between the stopper 310 and the work platform 200 increases, so that the spring string can pass through and continue to be transported to the next link. When the stopper 310 moves downward, the space between the stopper 310 and the work platform 200 decreases to hinder the transportation of the spring string and make the spring string abut against the stopper 310 to limit the spring string.

[0090] or Figure 4 As shown in the swing, when the limiter 310 swings to the horizontal, the space between the limiter 310 and the working platform 200 increases to allow the spring string to pass. When the limiter 310 swings to the vertical, the space between the limiter 310 and the working platform 200 decreases to hinder the conveyance of the spring string and make the spring string abut against the limiter 310 to limit the spring string.

[0091] The distance between the limiter 310 and the working platform 200 is changed by vertical movement or swinging of the limiter 310. In the process of assembling the spring gasket core, the limiter 310 is brought close to the working platform 200 to limit the spring string. After the spring gasket core is assembled, the height of the limiter 310 can be increased to increase the distance between the limiter 310 and the working platform 200, so that the entire spring gasket core formed after the spring string is assembled can pass through the bottom of the limiter 310 for subsequent processing operations. In addition, after one spring gasket core is assembled, the limiter 310 can be restored to its initial position to continue to limit the next group of spring strings.

[0092] In some embodiments, the stopper 310 may be connected to the frame via a rack and pinion mechanism to move in the vertical direction, or connected to the frame via a crank and rocker mechanism to swing relative to the frame 100 .

[0093] Reference Figure 5 In some embodiments, the stopper 310 includes an outer plate 311, an inner plate 312, a first magnet 313, and a driving member 314. The outer plate 311 is used to directly abut against the spring string and can be connected to the frame 100; the inner plate 312 is movably connected to the outer plate 311. The first magnet 313 is installed on the inner plate 312 and is located on the side of the inner plate 312 close to the outer plate 311. The driving member 314 is installed on the outer plate 311 and connected to the inner plate 312, and is used to drive the inner plate 312 and the first magnet 313 to move closer to or away from the outer plate 311.

[0094] When the limiting member 310 limits the spring string on the working platform 200, the inner plate 312 can be driven to approach the outer plate 311 through the driving member 314, and the first magnet 313 on the inner plate 312 contacts the outer plate 311, so that the outer plate 311 has magnetism. When the spring string is pushed to the working platform 200, the outer plate 311 with magnetic limiting member 310 absorbs the spring string to limit it, thereby improving the accuracy of the spacing position of each pocket spring and the stability of absorption when the spring string is bonded. When the limiting member 310 is separated from the spring string, the driving member 314 drives the inner plate 312 and the first magnet 313 away from the outer plate 311, and the outer plate 311 is demagnetized, so that the spring string loses its magnetic absorption and separates from the outer plate 311.

[0095] refer to Figure 1 and Figure 6 In some embodiments, the limiting mechanism 300 further includes a first support member 320 and a first support beam 330. The first support member 320 is disposed on the frame 100. The first support beam 330 is movably disposed on the first support member 320 and moves longitudinally relative to the first support member 320. The limiting member 310 is disposed on the first support beam 330 and slides vertically relative to the first support beam 330.

[0096] The extension direction of the first support beam 330 may be parallel to the extension direction of the stopper 310, and the first support beam 330 may be arranged across the top of the working platform 200. Two first support members 320 may be arranged, and are arranged at both ends of the first support beam 330, respectively. The two ends of the first support beam 330 are connected to the two first support members 320, respectively. The first support beam 330 and the first support member 320 may be slidably connected via a horizontal guide rail, so that the first support beam 330 and the stopper 310 arranged on the first support beam 330 may slide along the horizontal first direction relative to the frame 100. Similarly, the stopper 310 may be connected to the first support beam 330 via a vertical guide rail, so that the stopper 310 can slide along the vertical direction relative to the first support beam 330, thereby realizing the sliding of the stopper 310 in the vertical direction.

[0097] In actual use, a first driving assembly 340 and a second driving assembly 350 may be provided. The first driving assembly 340 is used to drive the first support beam 330 to slide, and the second driving assembly 350 is used to drive the limiting member 310 to slide.

[0098] Exemplarily, the first driving assembly 340 may include a first driving motor 341, a first driving shaft 342, a first gear 343, and a first rack 344. The first driving shaft 342 is rotatably arranged on the support beam, the first driving motor 341 is relatively fixed to the first support beam 330, and is connected to the first driving shaft 342 through a reduction gear box, and is used to drive the first driving shaft 342 to rotate. The first gear 343 is fixedly arranged on the first driving shaft 342, the extension direction of the first rack 344 is parallel to the first direction, and is fixed to the first support member 320, and the first rack 344 is meshed with the first gear 343. Therefore, the first driving motor 341 can drive the first driving shaft 342 and the first gear 343 to rotate, and drive the first gear 343 to move on the first rack 344, so as to achieve the purpose of moving the support beam in the first direction.

[0099] The second driving assembly 350 may include a second driving motor 351, a second driving shaft 352, a second gear 353 and a second rack 354. The second driving shaft 352 is rotatably disposed on the first support beam 330, and the second gear 353 is fixedly disposed on the second driving shaft 352. The second driving motor 351 is relatively fixed to the first support beam 330 and is connected to the second driving shaft 352 through a reduction gear box to drive the second driving shaft 352 to rotate. The second rack 354 is vertically disposed on the stopper 310 and meshes with the first gear 343. The second driving motor 351 drives the second driving shaft 352 and the second gear 353 to rotate, so that the stopper 310 can be driven to slide in the vertical direction.

[0100] Reference Figure 7In some embodiments, the working platform 200 is provided with a second magnet 210 for magnetically attracting a spring string placed on the working platform 200 .

[0101] Among them, the second magnet 210 can be an ordinary magnet or an electromagnet, which can be set on the inner side of the working platform 200. After the spring string is placed on the surface of the working platform 200, it can maintain a stable position under the action of the second magnet 210, so that the spacing between the pocket springs in the spring string can remain unchanged during the movement.

[0102] In some embodiments, the working platform 200 includes a conveyor belt, which is used to convey the spring string in the longitudinal direction. The second magnet 210 is located below the conveyor belt and is used to absorb the spring string.

[0103] The working platform 200 can be one or more belt conveyors arranged in parallel. The two ends of the working platform 200 are respectively a loading end and a unloading end. The spring string is placed upright on the upper surface of the working platform 200 from the loading end. Each row of spring strings is placed on the surface of the working platform 200. The belt conveyor of the working platform 200 drives the spring string to move a corresponding distance toward the unloading end, reserving space for the next placement of the spring string, so that multiple rows of spring strings are placed in sequence on the surface of the working platform 200 to form a spring pad core.

[0104] Reference Figure 1 and Figure 7-8 In some embodiments, the feeding mechanism 500 includes a second support member 510, a first conveying member 520 and a pushing member 530. The second support member 510 is disposed on the frame 100. The first conveying member 520 is disposed on the second support member 510, and the two first conveying members 520 are disposed opposite to each other to form a clamping channel.

[0105] The second support member 510 can be arranged on the side of the loading end close to the working platform 200, and the conveying direction of the first conveying member 520 corresponds to the position of the working platform 200. When loading, the pocket springs of corresponding lengths are sequentially placed in the clamping channel of the first conveying member 520, and moved to the set position under the clamping and conveying action of the first conveying member 520, and then the combined spring string is pushed to the surface of the working platform 200 by the pushing member 530, so as to realize the purpose of automatically combining the spring string and automatically loading the spring string.

[0106] The pusher 530 can be arranged inside the clamping channel of the first conveying member 520, and is slidably connected to the second supporting member 510 through a guide rod, and the spring string in the loading chamber is pushed out by sliding the pusher 530 toward the working platform 200. There can be two pushers 530, which correspond to the clamping channels, so that the two pushers 530 act on the two ends of the pocket spring respectively, so that the pocket spring is evenly stressed during the pushing process and maintains a vertical posture.

[0107] The first conveying member 520 may include at least two conveying elements, and a clamping channel is formed between two adjacent conveying elements.

[0108] The sliding of the pushing member 530 can be controlled by setting up a third driving component 540. The third driving component 540 can be a gear rack transmission structure, or a screw slider transmission structure, and can also be driven by components such as a hydraulic cylinder or a pneumatic cylinder. There is no specific limitation on this in this embodiment.

[0109] In some embodiments, the spring core assembly device further includes a pusher 530, which is movably disposed in the clamping channel and is used to push the spring string from the first conveying member 520 to the working platform 200. The pusher 530 includes a third magnet 531, a demagnetization mechanism 532, and a pusher body 533, and the pusher body 533 is disposed in the clamping channel; the third magnet 531 is used to magnetically attract the spring string during the pushing process, and the demagnetization mechanism 532 is respectively connected to the pusher body 533 and the third magnet 531, and is used to drive the third magnet 531 to contact or separate from the pusher body 533 after the spring string is pushed into place, thereby demagnetizing the pusher body 533 and separating it from the spring string.

[0110] Among them, the third magnet 531 can be an ordinary magnet or an electromagnet. The pusher body 533 can be a shell structure with a cavity, and the third magnet 531 is arranged on the inner side of the cavity of the pusher body 533. When the pusher 530 pushes the spring string out of the loading chamber, the third magnet 531 can be used to absorb the spring string to maintain the relative position and spacing of each pocket spring in the spring string, so that the spring string can be accurately positioned when it is moved to the working platform 200. After the spring string and the spring string on the front side of the working platform 200 are bonded to each other, the demagnetization mechanism 532 drives the third magnet 531 away from the pusher body 533, and the pusher body 533 is demagnetized, and then the pusher 530 retreats to the rear side of the loading chamber, and the spring string will not be driven back due to the magnetic force of the third magnet 531.

[0111] It should be noted that the distance between the two second support members 510 can be set according to the spring string with the smallest height in each row of spring strings, and the remaining spring strings can enter the loading chamber after elastic compression deformation, and after the push member 530 pushes the assembled spring string away from the loading chamber, each pocket spring restores its initial length. The demagnetization mechanism 532 can be a cylinder drive mechanism.

[0112] In some embodiments, in order to combine spring strings of different sizes, at least one of the two first conveying members 520 is slidably connected to the second supporting member 510 to change the size of the clamping channel.

[0113] At least one conveying element in the first conveying member 520 is slidably connected to the second supporting member 510 so as to change the distance between two adjacent conveying elements, thereby changing the size of the clamping channel.

[0114] Exemplarily, one of the conveying elements of the first conveying member 520 is relatively fixed to the second support member 510, and the other conveying element is slidably connected to the second support member 510 through a guide rail, and a fourth drive component 550 can be set to control it. The fourth drive component 550 can also be a gear rack transmission structure or a screw slider transmission structure, and can also be driven by components such as a hydraulic cylinder or a pneumatic cylinder. There is no specific limitation on this in this embodiment.

[0115] Reference Figure 7 and Figure 9-11 In some embodiments, the second support member 510 is rotatably disposed on the frame 100 so that the feeding mechanism 500 can be in any position of the first station, the second station, and the third station. When the feeding mechanism 500 is in the first station, the first conveying member 520 is arranged in the horizontal direction, and the clamping channel formed by the first conveying member 520 can be manually discharged. When the feeding mechanism 500 is in the second station, the first conveying member 520 is arranged in an inclined manner to receive the spring string cut to a set length, and the glue spraying mechanism 400 can pass between the first conveying member 520 and the working platform 200 to spray adhesive on the surface of the spring string. When the feeding mechanism 500 is in the third station, the first conveying member 520 is arranged in the vertical direction to convey the spring string to the working platform 200.

[0116] like Figure 7 As shown, the second support member 510 is rotatably connected to the frame 100 through a hinge shaft, and a fifth driving assembly 560 is provided to be connected to the second support member 510 to drive the second support member 510 to rotate. The fifth driving assembly 560 may include a driving gear 561, a driven gear 562 and a pull rod 563, the driving gear 561 and the driven gear 562 are both rotatably connected to the frame 100, and the driving gear 561 and the driven gear 562 are hinged to each other, one end of the pull rod 563 is hinged to the outer edge of the driven gear 562, and the other end is hinged to the second support member 510. The driving gear 561 is driven to rotate actively by the motor, and drives the rotation of the driven gear 562, and can drive the second support member 510 to rotate through the pull rod 563.

[0117] Combination Fig. 9When the feeding mechanism 500 is at the first station, the first conveying member 520 is distributed in the horizontal direction, the conveying elements of the first conveying member 520 are arranged relatively spaced in the horizontal direction, and the pushing member 530 is placed horizontally. At this time, the operator can manually lay the spring string in the clamping channel. In this way, when there is a broken spring, other materials such as sponge strips need to be added during the spring core processing, or a single spring core sample needs to be made, manual placement is performed, the flexibility of feeding is improved, and the adjustment time of the machine is saved.

[0118] Combination Fig.10 When the feeding mechanism 500 is at the second station, the first conveying member 520 and the pushing member 530 are both in an inclined position, so that the channel between the first conveying member 520 corresponds to the spring string feeding position, and is used to receive the spring string cut to a set length. The spring string in the working platform 200 is at a certain distance from the working platform 200, so that the glue spraying mechanism 400 can spray the adhesive from the front side of the spring string.

[0119] Combination Fig.11 When the feeding mechanism 500 is in the third working position, the first conveying member 520 is arranged in the vertical direction, and the conveying elements of the first conveying member 520 are arranged relatively to each other up and down, so that the spring string is in a vertical posture, and the surface of the first conveying member 520 located on the lower side is flush with the surface of the working platform 200, so that the spring string can be conveyed to the surface of the working platform 200 by the first conveying member 520.

[0120] Reference Figure 1 and Fig.12 In some embodiments, the spring core assembly device further includes a feeding mechanism 600, which corresponds to the position of the feeding mechanism 500 when it is in the second station, and is used to feed the bagged springs to the feeding mechanism 500. The feeding mechanism 600 includes a second conveying member 620, a clamping assembly 630, and a cutting assembly 640. Among them, the second conveying member 620 is used to feed the bagged springs to the feeding mechanism 500. The clamping assembly 630 is located at the discharge end of the second conveying member 620 and docks with the input end of the first conveying member 520 of the feeding mechanism 500. The clamping assembly 630 has a clamping chamber 631, and the clamping chamber 631 is used to accommodate continuous bagged springs. The cutting assembly 640 is arranged between the second conveying member 620 and the clamping assembly 630, and is used to cut the continuous bagged springs into a spring string of a set length.

[0121] The number of second conveying members 620 can be two, and the two second conveying members 620 are spaced apart in the vertical direction, so that the pocket spring can pass between the two second conveying members 620. When the feeding mechanism 500 is in the second station, the two first conveying members 520 correspond to the two second conveying members 620, so that the pocket spring can move from between the two second conveying members 620 to between the two first conveying members 520, thereby realizing the feeding function of the pocket spring. The feeding mechanism 500 can also include a third support member 610, and the second conveying member 620 is installed on the third support member 610.

[0122] The clamping assembly 630 may be composed of a bottom plate and a plurality of partitions disposed on the bottom plate, and a clamping chamber 631 is formed between each two adjacent partitions. There is at least one clamping chamber 631, and the clamping assembly 630 may be slidably connected to the third support member 610 through two sets of mutually perpendicular guide rails. The sliding of the clamping assembly 630 enables any clamping chamber 631 to be correspondingly connected to the second conveying member 620, so as to convey the pocket spring placed in the corresponding clamping chamber 631 to the second conveying member 620.

[0123] By placing bagged springs of different lengths in different clamping chambers 631 and connecting the corresponding clamping chambers 631 with the second conveying member 620 in sequence during the feeding process, the bagged springs of different lengths can be sequentially conveyed to the feeding chamber of the feeding mechanism 500 through the second conveying member 620 and combined into a spring string with a corresponding curvature.

[0124] Among them, because the bagged spring is composed of multiple springs of the same size, after the bagged springs of corresponding length are conveyed to the second conveying member 620, the cutting assembly 640 can be used to cut the bagged springs in series to achieve the purpose of obtaining bagged springs of corresponding length according to the size of the bagged springs.

[0125] The cutting assembly 640 may include a mounting bracket 641 and a cutter 642. The mounting bracket 641 is fixedly mounted on the third support member 610. There are two cutters 642, which are symmetrically mounted on the mounting bracket 641. The two cutters 642 are slidably connected to the mounting bracket 641 through a sliding rod and driven by a driving component such as a cylinder or a hydraulic cylinder. In the initial state, a gap is reserved between the two cutters 642 for the pocket spring to pass through. When the pocket spring string needs to be cut, the two cutters 642 are controlled to move toward the direction of the pocket spring string at the same time to cut the corresponding position of the pocket spring string.

The two spring plates 572 are respectively connected to the positioning driving unit 571 and move toward or away from each other under the drive of the positioning driving unit 571 to define the position of the spring string in the lateral direction. The spring plates 572 can rotate to avoid in the lateral direction, so that the bagged springs transported in the lateral direction can be smoothly transported into the feeding mechanism 500.

[0127] In some embodiments, the positioning drive unit 571 includes a driver 5711, a transmission member 5712, a finger cylinder 5713 and a vertical plate 5714.

The spring plate 572 is driven by the driver 571 to make the two spring plates 572 close to or away from each other, which is convenient for adaptive positioning of the spring string. The finger cylinder 5713 can also drive the spring plate 572 to flip and rotate to avoid in the horizontal direction, so that the bagged springs transported in the horizontal direction can be smoothly transported into the feeding mechanism 500. The vertical plate 5715 is located on the surface of the pushing member 530, and is used to abut against the limit in the longitudinal direction or push the spring string with the pushing member 530.
