Description

Technical Field

[0001] This utility model relates to the field of mattress processing, and in particular to a spring mattress edge-fitting system. Background Technology

[0002] A mattress is an item placed between the body and the bed to ensure consumers get a healthy and comfortable sleep. Mattresses come in a variety of materials, and different materials provide different sleep experiences. Spring mattresses are made of springs and are widely used due to their good elasticity, support, and breathability. Spring mattresses typically require a seam allowance, where steel edging is attached to the edges of the mattress to increase the firmness around the edges and ensure the overall rigidity of the mattress.

[0003] The glued edge foam is glued to the sides of the spring core to reinforce the foam on both sides of the spring core. It also increases the overall integrity of the mattress and the comfort of the sides. In some spring mattresses where the spring core is not reinforced with edge steel, the glued edge foam also serves the same reinforcement function as the edge steel.

[0004] Currently, the traditional method for edge-fitting spring cores is done manually. This method requires manual edging of the top and four sides of the spring core, followed by flipping the spring core over and then edging the bottom surface. The entire process consumes a lot of manpower and resources. In particular, flipping the spring core often requires the coordinated work of multiple people, which is very troublesome and inefficient.

[0027] By setting the bottom / top cotton feeding platform and the spring core feeding platform on both sides of the feeding conveyor belt, instead of distributing them directly on the same side of the feeding conveyor belt, the subsequent gripping mechanism can reduce the travel distance of the gripping mechanism when gripping the bottom / top cotton and placing the spring core on the feeding conveyor belt, resulting in higher feeding efficiency and a more compact structure for the entire feeding unit.

[0028] The design of the first edge-bonding unit, by setting up vertically distributed lifting conveyor belts and horizontal conveyor belts, and coordinating the vertical lifting of the lifting conveyor belts and the horizontal movement of the horizontal conveyor belts, achieves bonding of the first semi-finished product with the side cotton strips while also realizing the transitional conveying of the top cotton, thus improving bonding efficiency.

[0029] The material detection switch on the bonding bracket is designed to detect whether there is a side cotton strip on the side cotton strip bracket, so as to ensure that the side cotton strip is bonded to the side of the spring core in the future and avoid the phenomenon of missing bonding.

[0030] The design of the second edge-fitting unit, through the upper and lower distributed bonding conveyor belts and pressing conveyor belts, combined with the action of vacuum suction cups and pressing cylinders, achieves the flipping of the top surface so that the top surface can be smoothly pressed onto the upper surface of the second semi-finished product.

[0041] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0042] like Figures 1-10 The spring mattress shown is a spring core 6. Top and bottom pads are attached to the top and bottom sides of the spring core 6, respectively. The top and bottom pads have the same structure. Side pads 61 are attached around the spring core 6. The four side pads 61 work together to form a U-shaped structure. The spring core 6 is placed in the cavity of the U-shaped structure. The top and bottom pads are attached to the top and bottom sides of the spring core 6 and the side pads 61, respectively, and cover the spring core 6 and the side pads 61.

[0043] The edge-attaching system includes a feeding unit 1, an adhesive application unit 2, a first edge-attaching unit 3, a second edge-attaching unit 4, and an unloading unit 5 arranged in a straight line.

[0044] The distribution direction of feeding unit 1, gluing unit 2, first edge-attaching unit 3, second edge-attaching unit 4 and unloading unit 5 is defined as the first direction, and another horizontal direction perpendicular to the first direction is defined as the second direction.

[0045] The feeding unit 1 is used for conveying the spring core 6, initially bonding the spring core 6 with the bottom cotton to form the first semi-finished product, and also for conveying the top cotton.

[0046] Specifically, such as Figure 3 , Figure 4 As shown in the schematic diagram, the feeding unit 1 includes a feeding conveyor belt 11, a bottom / top cotton feeding platform 12, a spring core feeding platform 13, and a gripping mechanism. The bottom / top cotton feeding platform 12, the feeding conveyor belt 11, and the spring core feeding platform 13 are distributed sequentially along the second direction. Several bottom / top cotton sheets are stacked vertically on the bottom / top cotton feeding platform 12. In this invention, the bottom and top cotton sheets have the same structure, so the same type of sheet cotton can be used as both bottom and top cotton sheets. Several spring cores 6 are stacked vertically on the spring core feeding platform 13. By setting the bottom / top cotton feeding platform 12 and the spring core feeding platform 13 on opposite sides of the feeding conveyor belt 11, instead of directly distributing them on the same side of the feeding conveyor belt 11, the subsequent gripping mechanism can reduce its travel distance when gripping the bottom / top cotton and placing the spring cores 6 on the feeding conveyor belt 11, resulting in higher feeding efficiency and a more compact structure for the entire feeding unit 1.

[0047] The feeding conveyor belt 11 is installed on the feeding conveyor support and is driven by the feeding motor installed on the feeding conveyor support to convey the spring core 6 or the bottom cotton and top cotton. The conveying direction of the feeding conveyor belt 11 is consistent with the first direction.

[0048] The material gripping mechanism includes a material gripping bracket 14 and a needle frame 15 mounted on the material gripping bracket 14. There are multiple needle frames 15, and multiple needle components for gripping bottom / top cotton or spring core 6 are mounted on the needle frames 15.

[0049] The acupuncture assembly includes a pair of parallel acupuncture seats 16, which are fixed to the acupuncture frame 15 by bolts. At least one inclined grasping needle 18 is installed on the acupuncture seat 16. In this embodiment, two parallel grasping needles 18 are installed on the same acupuncture seat 16, and the grasping needles 18 on the two acupuncture seats 16 are distributed in a V-shape. The grasping needles on the two acupuncture seats 16 are staggered. The grasping needles 18 are driven to extend and retract vertically by a linear actuator 17 installed on the acupuncture seat 16. In this embodiment, the linear actuator 17 can be a cylinder, a pneumatic telescopic rod, a moving push rod, or a similar linear drive element.

[0050] The needle-punching assembly moves horizontally in the second direction or moves up and down vertically under the drive of the needle-punching frame 15. Specifically, the drive is as follows: the material-gripping bracket 14 is a gantry structure composed of a pair of uprights and a crossbeam. The needle-punching assembly is mounted on the needle-punching frame 15 through the cooperation of the first transition bracket 19 and the second transition bracket. A horizontally arranged rack and guide rail are installed on the crossbeam of the material-gripping bracket 14, with the rack and guide rail arranged side by side and extending in the same direction. A gear and slider that cooperate with the rack and guide rail on the crossbeam are installed on the second transition bracket, and the gear is driven to rotate by a motor mounted on the second transition bracket. This causes the second transition bracket to move horizontally on the crossbeam of the material gripping bracket 14. The first transition bracket 19 is vertically installed beside the crossbeam of the material gripping bracket 14. A pair of vertically installed guide rails are also installed on both sides of the first transition bracket 19. At the same time, a slider that cooperates with the guide rails on the first transition bracket 19 is installed on the second transition bracket. The first transition bracket 19 is driven to move up and down by a lifting cylinder installed on the second transition bracket. The needle frame 15 is fixedly installed at the bottom of the first transition bracket 19, so that it moves up and down or horizontally synchronously with the up and down movement of the first transition bracket 19 and the horizontal movement of the second transition bracket.

[0051] The gluing unit 2 is used to spray glue onto the surface of the bottom or top cotton.

[0052] Specifically, such as Figure 5 , Figure 6 As shown in the schematic diagram, the gluing unit 2 includes a gluing conveyor belt 21, a gluing bracket 22, a glue box, and a glue spraying assembly.

[0053] The gluing conveyor belt 21 is mounted on a gluing conveyor support and is driven by a gluing motor mounted on the gluing conveyor support. The conveying direction of the gluing conveyor belt 21 is consistent with the first direction.

[0054] The glue-applying bracket 22 is a gantry-type structure that spans both sides of the glue-applying conveyor belt 21. The glue box is installed on the outer wall of one side of the glue-applying bracket 22.

[0055] The glue spraying assembly includes a crossbeam 23 located above the glue conveyor belt 21. The two sides of the crossbeam are fixed to the glue support 22. A first glue spray nozzle and a second glue spray nozzle 25 are respectively installed on the two sides of the crossbeam 23 in the first direction. There is one first glue spray nozzle, which reciprocates along the second direction on the crossbeam 23. The first glue spray nozzle is installed on the crossbeam 23 through a glue nozzle sliding seat 26. A guide rail and a rack extending horizontally along the second direction are also installed on the crossbeam 23, and the guide rail and rack are distributed vertically on the crossbeam 23. At the same time, a slider and a gear that cooperate with the guide rail and the rack are also installed on the glue nozzle sliding seat 26. The gear is driven by a motor installed on the glue nozzle sliding seat 26 to rotate, thereby driving the glue nozzle sliding seat 26 to move horizontally along the guide rail, thus realizing the reciprocating movement of the first glue spray nozzle on the crossbeam 23.

[0056] Several second nozzles 25 are fixedly mounted on the crossbeam 23 along the second direction. The second nozzles 25 are mounted on the crossbeam 23 through the cooperation of nozzle fixing seats. The two sides of the nozzle fixing seats are mounted on the crossbeam 23 through the cooperation of tightening bolts. More preferably, a guide rail is also installed on the crossbeam 23 to facilitate the sliding installation of the nozzle fixing seats. A slider that cooperates with the guide rail is installed on the nozzle fixing seat. The nozzle fixing seat slides horizontally along the guide rail and is tightened and fixed by tightening bolts after sliding to the desired position. Both the first nozzle and the second nozzle 25 are connected to the glue tank through the cooperation of hoses and are supplied with glue by the glue tank.

[0057] The first edge-fitting unit 3 is used to bond the first semi-finished product and the side cotton strip 61 to form the second semi-finished product, and to provide transitional conveying for the top cotton.

[0058] Specifically, such as Figures 7-9 As shown in the schematic diagram, the first edge-fitting unit includes a first edge-fitting bracket 31, on which vertically distributed lifting conveyor belts 32 and horizontally distributing conveyor belts 33 are mounted.

[0059] The lifting conveyor belt 32 is mounted on a lifting conveyor support and driven by a motor mounted on the lifting conveyor support. The lifting conveyor support is mounted on the first side support 32 through the cooperation of chains and sprockets, and moves up and down along the first side support 32. Specifically, each sprocket is mounted on the upper and lower sides of the first side support 32, one side of the chain is connected to the upper side of the lifting conveyor support, and the other side of the chain passes through the upper sprocket and the lower sprocket in sequence before connecting to the lower side of the lifting conveyor support. One sprocket is driven to rotate by the motor mounted on the first side support 32, thereby driving the lifting conveyor support to move up and down, and finally realizing the lifting of the lifting conveyor belt 32. Vertical guide rails are also provided on the side wall of the first side support 32, and sliders that cooperate with the guide rails are also installed on the lifting conveyor support. The cooperation between the guide rails and the sliders plays a guiding role in the up and down movement of the lifting conveyor belt 32.

[0060] The translational conveyor belt 44 is mounted on the first edge support 32 through the cooperation of guide rails and sliders, and moves horizontally along the second direction under the drive of gears and racks. Specifically, there are two guide rails, which are installed side by side on both sides of the first edge support 32 along the first direction, and the two guide rails extend along the second direction. The rack is installed on one side of the first edge support 32 and also extends in the second direction. The translational conveyor belt 44 is mounted on a translational conveyor bracket and is driven by a motor mounted on the translational conveyor bracket. The slider and gear are mounted on the translational conveyor bracket to cooperate with the guide rails and racks. The gear is driven and rotated by the motor mounted on the translational conveyor bracket, thereby driving the extended guide rails of the translational conveyor bracket to move horizontally in the second direction, thereby realizing the horizontal movement of the translational conveyor belt 44.

[0061] By setting up vertically distributed lifting conveyor belts 32 and horizontal conveyor belts 33, and coordinating the vertical lifting of the lifting conveyor belts 32 and the horizontal movement of the horizontal conveyor belts 33, this staggered movement method achieves the bonding of the first semi-finished product with the side cotton strips 61, while also realizing the transitional conveying of the top cotton, thus improving bonding efficiency.

[0062] Side strip bonding components are respectively provided on both sides of the first edge bonding bracket 32. There are three side strip bonding components on one side, which are distributed in a U-shape around the first edge bonding bracket 32. There is one side strip bonding component on the other side. The lifting conveyor belt 32 is located on the side of the first edge bonding bracket 32 ​​with only one side strip bonding component. The four side strip storage components work together to bond the side strips 61 around the first semi-finished product.

[0063] The side strip bonding assembly includes a bonding bracket 34 and a side strip gripping mechanism mounted on the bonding bracket 34.

[0064] The bonding bracket 34 is located beside the first edge-bonding bracket 32. A side cotton strip material pile is also provided on the side of the bonding bracket 34 away from the first edge-bonding bracket. The bonding bracket 34 moves closer to or away from the side cotton strip material pile under the action of gears and racks. Specifically, a movable seat 35 is provided on each side of the side cotton strip material pile. A movable guide rail is installed on the side of the two movable seats 35 that are adjacent to each other. A movable slider that cooperates with the movable guide rail is installed on the bonding bracket 34. A movable rack is also installed on the upper surface of the movable seat 35. The extension direction of the movable rack is consistent with the extension direction of the movable guide rail. A movable gear that meshes with the movable rack is also installed on the bonding bracket 34. One of the movable gears is driven by a motor installed on the bonding bracket 34 to rotate, thereby driving the bonding bracket 34 to move horizontally, thus moving back and forth between the side cotton strip material pile and the first edge-bonding bracket 32.

[0065] The side tampon gripping mechanism includes a side tampon holder with a tampon placement cavity for placing side tampons. The side tampon holder includes a base plate 35 and three side plates 36 connected to the base plate 35. The base plate 35 is a rectangular plate, and the three side plates 36 are respectively connected to two short axis sides and one long axis side of the base plate. The base plate 35 and the three side plates 36 cooperate to form a tampon placement cavity with an opening at the top and one side.

[0066] Several side cotton strip needles are installed on the side cotton strip bracket, and each side cotton strip needle moves under the action of an independent cylinder 37, thereby moving into or out of the cotton strip placement cavity. The cylinder 37 is directly fixed on the side plate 36, and a through hole is also opened on the side plate 36 to allow the side cotton strip needles to pass through and move.

[0067] The side tampon holder moves up and down along the fitting bracket 34, and rotates under the drive of a rotary motor. Specifically, the side tampon holder is installed on the fitting bracket 34 through a transition seat 38. The side plates 36 on both sides of the side tampon holder are installed on the transition seat 38 through bearings. The side tampon holder is driven to rotate by a rotary motor installed on the transition seat 38. A pair of vertically arranged lifting guide rails are also installed on both sides of the fitting bracket 34. At the same time, lifting sliders that cooperate with the lifting guide rails are installed on both sides of the transition seat 38. The transition seat 38 is driven by a lifting cylinder installed on the fitting bracket 34 to move up and down along the lifting guide rails, thereby driving the side tampon holder to move up and down.

[0068] A material detection switch is also installed on the bonding bracket 34. The material detection switch is mounted on the bonding bracket 34 via a detection seat 39, which is located above the side cotton strip bracket. A guide rail is provided on the bonding bracket 34 to allow the detection seat 39 to move back and forth. A slider that mates with the guide rail is installed at the bottom of the detection seat 39. The detection seat 39 is fixed to the bonding bracket 34 by a tightening bolt. The material detection switch 39 on the bonding bracket 34 is designed to detect whether there is a side cotton strip on the side cotton strip bracket, ensuring that the side cotton strip 61 is bonded to the side of the spring core 6 in the subsequent process, and avoiding any missed bonding.

[0069] The second edge-fitting unit 4 is used to bond the second semi-finished product with the top foam to form the finished spring mattress.

[0070] Specifically, such as Figure 10 As shown in the schematic diagram, the second edge-fitting unit 4 includes a second edge-fitting bracket. An upper and lower edge-fitting conveyor belt 43 and a pressing conveyor belt 42 are installed on the second edge-fitting bracket. A gap is left between the edge-fitting conveyor belt 43 and the pressing conveyor belt 42 to allow the finished spring mattress to pass through. A rotating bracket is also installed on the second edge-fitting bracket to drive the edge-fitting conveyor belt 43 and the pressing conveyor belt 42 to rotate. The pressing conveyor belt 42 is driven by a pressing cylinder installed on the rotating bracket to move closer to or away from the edge-fitting conveyor belt 43. In this embodiment, the pressing cylinder is a pneumatic cylinder. A vacuum suction cup is also installed on the pressing conveyor belt 42.

[0071] The coordination between the rotating support, the second edge-fitting support, the bonding conveyor belt 43, and the pressing conveyor belt 42 is as follows: The rotating support includes a pair of parallel rotating frame frames 41, which are connected by a rotating shaft. The two sides of the rotating shaft are mounted on the second edge-fitting support through the cooperation of bearings and bearing seats, and are driven to rotate by a rotary motor mounted on the second edge-fitting support. This, in turn, causes the bonding conveyor belt 43 and the pressing conveyor belt 42 to rotate, realizing the switching of their vertical positions. The two sides of the bonding conveyor belt 43 are directly fixed to the rotating frame frames 41, and the two sides of the pressing conveyor belt 42 are mounted on the rotating frame frames 41 through the cooperation of pressing cylinders, and move closer to or away from the bonding conveyor belt 43 under the action of the pressing cylinders. Through the design of the vertically distributed bonding conveyor belt 43 and pressing conveyor belt 42, combined with the action of the vacuum suction cup and the pressing cylinders, the top surface is flipped so that the top surface can be smoothly pressed onto the upper surface of the second semi-finished product.

[0072] The unloading unit 5 is used for unloading and conveying the laminated spring mattress.

[0073] Specifically, the unloading unit 5 includes an unloading conveyor belt 51, which is mounted on an unloading conveying bracket and driven by an unloading motor mounted on the unloading conveying bracket. The conveying direction of the unloading conveyor belt 51 is consistent with the first direction.

[0074] Working Principle: During the bonding process of the spring mattress, firstly, a piece of mattress is gripped from the bottom / top mattress feeding platform 12 using a material gripping mechanism and placed on the feeding conveyor belt 11 as the bottom mattress. Then, the feeding conveyor belt 11 transports the bottom mattress to the adhesive conveyor belt 21. Adhesive is sprayed onto the upper surface of the bottom mattress using a first and second adhesive nozzle 25. The moving first adhesive nozzle sprays adhesive onto both sides of the bottom mattress in the first direction, while multiple fixed second adhesive nozzles 25 spray adhesive onto both sides and the central area of ​​the bottom mattress in the first direction. After adhesive spraying, the mattress returns to the feeding conveyor belt 11, and then... The material gripping mechanism picks up a spring core 6 from the spring core feeding platform 13 and places it in the middle area of ​​the base cotton, so as to achieve the bonding of the spring core 6 and the base cotton to form the first semi-finished product. Then, the first semi-finished product is transported to the translation conveyor belt 33 via the feeding conveyor belt 11 and the glue spraying conveyor belt 21. At this time, the side strip bonding assembly is used to bond the side cotton strip 61 to one side of the first semi-finished product. After the bonding is completed, it is moved to the other side of the first edge bonding bracket 32 ​​via the translation conveyor belt 33. The three side strip bonding assemblies are used to bond the side cotton strip 61 to the other three sides of the first semi-finished product to form the second semi-finished product.

[0075] While the side strips 61 of the first semi-finished product are being bonded, a piece of cotton is picked up from the bottom / top cotton feeding platform 12 by a material grabbing mechanism and placed on the feeding conveyor belt 11 as top cotton. The feeding conveyor belt 11 then transports the top cotton to the gluing conveyor belt 21. The first and second glue nozzles 25 are used to spray glue onto the upper surface of the top cotton. As the translation conveyor belt 33 moves to the other side of the first edge-fitting bracket 32, the lifting conveyor belt 32 descends to the same horizontal height as the translation conveyor belt 33. The glued top cotton is then transported from the gluing conveyor belt 21 to the lifting conveyor belt 32. The top cotton is then conveyed to the second edge-fitting unit 4 by the lifting conveyor belt 32. At this time, the bonding conveyor belt 43 is on top and the pressing conveyor belt 42 is on the bottom. That is, the top cotton will be conveyed onto the pressing conveyor belt 42. After the lifting conveyor belt 32 finishes conveying the top cotton, it moves upward and returns to its original position. The top cotton on the pressing conveyor belt 42 is adsorbed onto the pressing conveyor belt 42 by the cooperation of the vacuum suction cup. Then, the rotating frame 41 rotates 180° so that the bonding conveyor belt 43 is on the bottom and the pressing conveyor belt 42 is on the top.
