Description

Technical Field

[0001] This invention relates to the field of mattress manufacturing, and in particular to a flexible fabric grasping and sorting device. Background Technology

[0002] Typically, during mattress manufacturing, a flexible fabric is attached to the mattress core. The user's torso comes into contact with this fabric, ensuring both support and comfort. During attachment, the flexible fabric needs to be transferred to the top of the mattress core. The nature of the flexible fabric makes this process difficult to execute, and it's prone to wrinkling, requiring significant manual intervention and increasing manufacturing costs. Furthermore, both the mattress core and the flexible fabric need precise positioning during attachment to ensure the flexible fabric completely covers the edges of the mattress core.

[0003] In related technologies, perforated plates are used to grip flexible fabrics. By pumping air, a negative pressure is created between the perforated plate and the flexible fabric, which adsorbs the flexible fabric onto the perforated plate. The flexible fabric is then transported to the target location. When the flexible fabric has various sizes, perforated plates of corresponding sizes can be manufactured to adsorb the flexible fabric at different locations, thus avoiding wrinkles at the edges of the flexible fabric during transportation. This results in poor versatility and also fails to solve the alignment problem between the bed core and the flexible fabric. Summary of the Invention

[0004] To solve at least one of the above-mentioned technical problems, the present invention provides a flexible fabric gripping and sorting device, the technical solution of which is as follows:

[0005] This invention provides a flexible fabric gripping and sorting device, comprising a frame and a sorting mechanism.

The inner frame is positioned above the outer frame, and the sorting components are mounted on the outer frame, with each sorting component spaced apart around the outer frame. The sorting mechanism further includes a height adjustment component and a rotation component. The height adjustment component connects the inner frame and the outer frame, allowing the outer frame to move vertically relative to the inner frame. The inner frame is rotatably connected to the frame via the rotation component, which drives the inner frame to rotate horizontally. Each sorting component includes a first driving member and a gripping mechanism. The gripping mechanism grips and secures a portion of the fabric material. Each gripping mechanism of each sorting component, driven by its respective first driving member, can independently move away from or towards the edge of the outer frame to sort and flatten the flexible fabric.

[0006] The embodiments of the present invention have at least the following beneficial effects: In the present invention, the flexible fabric is first placed below the finishing mechanism by the feeding device. Since the dimensions of each flexible fabric are not exactly the same, wrinkles are easily generated during the feeding device processing. The finishing mechanism is lowered to the flexible fabric by the height adjustment component. At the same time, the first driving component transports the pressure block and clamping plate to the edge of the flexible fabric. During the rotation, the clamping plate works with the pressure block to clamp the edge of the flexible fabric and flatten the flexible fabric. After the flexible fabric is flattened, the first and second pins are inserted into the flexible fabric alternately to maintain the flattened state of the flexible fabric. The flexible fabric is gripped in the flattened state, the height of the bed core is raised, and the height of the flexible fabric is lowered to completely cover the end of the bed core, ensuring the quality of the bonding process.

[0012] In some embodiments of the present invention, the gripping mechanism includes a clamping plate assembly for clamping the edge of the fabric;

[0013] The clamping plate assembly includes a pressure block, a clamping plate, and a second driving member. The second driving member drives the clamping plate to flip so that the clamping plate moves closer to or away from the pressure block, thereby clamping or releasing the edge of the flexible fabric.

[0014] In some embodiments of the present invention, the surface of the pressure block is provided with an anti-slip structure, and the surface cooperates with the clamping plate to clamp the flexible fabric.

[0029] This section will combine Figures 1 to 4 Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] In the description of this invention, it should be understood that the terms "center," "middle," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential," indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the 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 the invention. Features defined with "first" and "second" are used to distinguish feature names and do not have special meanings. Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] This invention provides a flexible fabric gripping and sorting device, which includes a frame 101 and a sorting mechanism.

[0033] The frame 101 can be set on the ground, and the frame 101 is used to set the sorting mechanism so that the sorting mechanism is in a horizontal state, thereby making the bed core fit with the flexible fabric in a horizontal state, which makes it easier to ensure the uniformity of the fit of the flexible fabric and improve product quality.

[0034] like Figure 1 As shown, the finishing mechanism is mounted on frame 101. Due to its physical properties, the flexible fabric is prone to wrinkling. Understandably, wrinkled flexible fabric adhering to the mattress core significantly impacts product quality. When a user lies on the mattress, the wrinkled fabric can cause a feeling of something stuck to their torso. The finishing mechanism not only smooths out the wrinkles in the flexible fabric but also, once smoothed, grasps the fabric, temporarily separating it from the mattress core. After the mattress core is repositioned, the flexible fabric is then reattached, facilitating mutual positioning between the fabric and the core. This ensures the flexible fabric completely covers the end face of the mattress core, further improving product quality.

[0035] Furthermore, the finishing mechanism includes an outer frame 102, an inner frame 103, and finishing components 200. The inner frame 103 is located above the outer frame 102, and the inner frame 103 is connected to the outer frame 102 to form a whole. The finishing components 200 are disposed on the outer frame 102. The finishing components 200 are arranged around the outer frame 102, and the finishing mechanism performs both flattening and gripping functions through the finishing components 200. It is understandable that, due to the large coverage area of ​​the flexible fabric, a single finishing component 200 cannot complete the flattening and gripping work over a large area. Therefore, multiple finishing components 200 are provided. To ensure uniform force on the flexible fabric, each finishing component 200 is symmetrically arranged at the edge of the flexible fabric, and the finishing components 200 are spaced apart from each other.

[0036] like Figure 2 , Figure 3 As shown, the finishing component 200 includes a first driving member and a gripping mechanism. The gripping mechanism includes a pin assembly and a clamping plate assembly. The pin assembly is disposed on the first driving member. The first driving member can move on the finishing component. The position of the pin assembly changes with the first driving member to adapt to flexible fabrics of different sizes and improve the versatility of the finishing component 200.

[0037] The clamping plate assembly and the insert pin assembly are fixedly connected. The first driving member drives the clamping plate assembly and the insert pin assembly to move away from or towards the edge of the outer frame 102. When the clamping plate assembly clamps the edge of the fabric, the clamping plate assembly moves outward, thereby spreading the fabric flat.

[0038] Furthermore, the pin assembly is used to grip the flexible fabric. The pin assembly includes several first pins 104 and several second pins 105. According to the physical properties of the flexible fabric, when the first pins 104 and second pins 105 move towards the flexible fabric, they can insert into the flexible fabric until they emerge, thereby temporarily fixing the flexible fabric to the pin assembly and achieving the gripping function. Each contact point between each first pin 104 and each second pin 105 and the flexible fabric can apply a lifting force to the flexible fabric, thereby ensuring that the force points on the flexible fabric are distributed and avoiding damage to the structure of the flexible fabric.

[0039] Specifically, the first pins 104 are parallel to each other, and the second pins 105 are parallel to each other. At the same time, in order to further improve the gripping ability of the pin assembly, the first pins 104 and the second pins 105 are at an angle and are staggered. When the flexible fabric is inserted into the first pins 104 and the second pins 105, the first pins 104 and the second pins 105 hold the flexible fabric in place to prevent it from falling off.

[0040] The inner frame 103 facilitates the movement of the entire finishing mechanism, allowing for changes in the height difference between the flexible fabric and the bed core, and enabling the finishing mechanism to rotate. The finishing mechanism also includes a height adjustment component and a rotation component. The height adjustment component connects the inner frame 103 and the outer frame 102, allowing the outer frame 102 to move vertically relative to the inner frame 103. The rotation component is connected to the frame 101, and the inner frame 103 is rotatably connected to the frame 101 via the rotation component, which drives the inner frame 103 to rotate horizontally.

[0041] In some examples, the first drive unit is disposed on the outer frame and includes a first motion unit and a second motion unit. The first motion unit and the second motion unit are capable of relative movement, thereby driving the pin assembly and the clamping plate assembly to move. It is understood that the pin assembly and the clamping plate assembly are disposed on the second motion unit. The first motion unit and the second motion unit can adopt various structural forms.

[0042] The first motion unit is configured as a first lead screw 201, and the second motion unit is configured as a first nut structure 202. The first lead screw 201 and the first nut structure 202 mesh together. When the first lead screw 201 rotates, the first nut structure 202 can move along the direction of the first lead screw 201. The pin assembly is disposed on the first nut structure 202. When the first nut structure 202 moves, the pin assembly moves together, so that the pin assembly is adjusted to the edge of the flexible fabric to adapt to the size of the flexible fabric.

[0043] Furthermore, a guide rod is provided next to the first lead screw 201, and the first nut structure 202 is sleeved on the guide rod to prevent the first nut structure 202 from rotating together with the first lead screw 201, thus preventing the lead screw and nut structure from failing. It is understood that the guide rod is parallel to the first lead screw 201.

[0044] Alternatively, the first driving component includes a moving motor, a belt, and pulleys, with the gripping mechanism mounted on the belt. The moving motor drives the belt, which in turn drives the gripping mechanism to move.

[0045] In some examples, the insert assembly also includes two insert cylinders, which are respectively connected to each first insert 104 and each second insert 105, and the two cylinders respectively drive each first insert 104 and each second insert 105 to perform linear motion. During the motion, the first insert 104 and the second insert 105 move closer to each other or further away from each other, thereby inserting into or detaching from the flexible fabric.

[0046] In some examples, a connecting portion 203 is provided between the first pin 104 and the second pin 105. The connecting portion 203 first abuts against the flexible fabric, and then drives the first pin 104 and the second pin 105 to insert into the flexible fabric. This standardizes the insertion form of the first pin 104 and the second pin 105, avoiding slight differences in the connection methods between different pin assemblies and the flexible fabric, which could cause the flexible fabric to tilt. Specifically, the connecting portion 203 is provided with a plurality of pin channels, which are arranged along the extension direction of each first pin 104 and each second pin 105. Each first pin 104 and each second pin 105 can pass through each pin channel to avoid interference.

[0047] In some examples, the clamping assembly includes a pressure block 204, a clamping plate 208, and a second driving member. The pressure block 204 is disposed on the second motion unit, and the surface of the pressure block 204 is provided with an anti-slip structure, so as to cooperate with the clamping plate 208 to clamp the flexible fabric. Specifically, the anti-slip structure is configured as a plurality of spikes 205. When the pressure block 204 abuts against the surface of the flexible fabric, the spikes 205 are embedded in the flexible fabric, increasing the contact area between the pressure block 204 and the flexible fabric and ensuring the positional stability of the flexible fabric.

[0048] In some examples, mounting plate 206 and clamping plate 208 are disposed on pressure block 204. Clamping plate 208 is hinged to pressure block 204. Clamping plate 208 includes a first straight portion and a second straight portion, with the first straight portion and the second straight portion forming an angle. The first straight portion is hinged to pressure block 204, and the second straight portion extends from the first straight portion toward pressure block 204. During the rotation of clamping plate 208, the second straight portion can move closer to or further away from pressure block 204. A second driving member is disposed on mounting plate 206. Specifically, the second driving member is a telescopic rod 207. The first end of telescopic rod 207 is hinged to mounting plate 206, and the second end of telescopic rod 207 is hinged to clamping plate 208. Understandably, the length of the telescopic rod 207 can change. When the length of the telescopic rod 207 decreases, the second straight section of the driving clamp 208 gradually moves away from the pressure block 204 and away from the flexible fabric. When the length of the telescopic rod 207 increases, the second straight section of the driving clamp 208 gradually moves closer to the pressure block 204 and closer to the flexible fabric. At this time, the second straight section of the clamp 208 and the pressure block 204 clamp the edge of the flexible fabric, thereby flattening the flexible fabric.

[0049] In some examples, multiple height adjustment components are provided, and each height adjustment component is interconnected by a synchronous motion structure. The synchronous motion structure drives each height adjustment component to move synchronously, thereby maintaining the level of the tidying mechanism.

[0050] Furthermore, the height adjustment assembly includes a second lead screw 301 and a second nut structure 302. The second lead screw 301 is vertically arranged, and the second nut structure 302 meshes with the second lead screw 301. When the second lead screw 301 rotates, the second nut structure 302 moves along the direction of the second lead screw 301, or the rotation of the second nut structure 302 drives the second lead screw 301 to move. The second nut structure 302 is mounted on the inner frame 103, and the second lead screw 301 is fixedly mounted on the outer frame 102. When the second nut structure 302 rotates, the outer frame 102 adjusts its height along with the second lead screw 301, thereby increasing the height of the sorting mechanism. Specifically, the height adjustment assembly can also employ chain drive, belt drive, cylinder, or other transmission methods.

[0051] The synchronous motion structure employs a synchronous belt 303, with each height adjustment component distributed around the center of the inner frame 103 and connected via the synchronous belt 303. Furthermore, the synchronous belt 303 is positioned to bypass each of the second nut structures 302. When the synchronous belt 303 rotates, each of the second nut structures 302 rotates simultaneously with the same amplitude, raising all parts of the inner frame 103 to the same height and maintaining the tidying mechanism in a horizontal state.

[0052] In some examples, the rotating assembly includes a motor 304 and a reducer 305. The output end of the motor 304 is connected to the input end of the reducer 305. The fixed part of the reducer 305 is connected to the frame 101, and the rotating part of the reducer 305 is connected to the inner frame 103. When the motor 304 rotates, the finishing mechanism can rotate relative to the frame 101, thereby adjusting the horizontal position of the flexible fabric.

[0053] During use, the flexible fabric is placed below the finishing mechanism via a feeding device. The finishing mechanism descends to the flexible fabric under the action of the height adjustment component. Simultaneously, the first driving component conveys the pressure block 204 and clamping plate 208 to the edge of the flexible fabric. During the rotation of the clamping plate 208, it works in conjunction with the pressure block 204 to clamp the edge of the flexible fabric and flatten it. After the flexible fabric is flattened, the first pin 104 and the second pin 105 are inserted into the flexible fabric alternately to maintain the flattened state of the flexible fabric and to grasp the flexible fabric in the flattened state. At this time, the clamping plate 208 retracts by rotating. The height of the bed core is raised, and the height of the flexible fabric is lowered to completely cover the end of the bed core, ensuring the quality of the bonding process.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0055] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
