Description

Technical Field

[0001] This invention relates to the field of fabric processing technology, and in particular to a low-tension anti-wrinkle fabric laying system. Background Technology

[0002] Before use, automotive interior and seat fabrics need to be laid out and cut. Traditionally, laying out and cutting are done by hand. However, with the continuous development of technology, manual operation can no longer meet the needs of large-scale processing. The manual method of laying out fabric is gradually being replaced by automatic fabric laying machines. Currently, commonly used automatic fabric spreading machines generally include an unwinding mechanism, a spreading head, and a spreading table. The spreading head drives the unwound fabric to reciprocate and cut on the spreading table to complete the entire spreading process. During this process, after the fabric roll is unwound, a tension adjusting roller is usually set between the spreading table and the unwinding mechanism. The tension adjusting roller is used to keep the fabric in a taut state. This taut state reduces the impact of the unwinding action and prevents wrinkles. However, this taut state can lead to excessive overall tension of the fabric. After being laid flat and cut, the fabric will have obvious deformation problems in all directions. When the spreading head pulls the fabric, the local tension between the fabric and the machine is too large, which will cause deformation and may also damage the internal structure. It is especially unsuitable for processing relatively thin and low-strength fabrics. In addition, due to the large width of the fabric, existing automatic fabric spreading machines require at least two people to pull the fabric from both sides of the spreading machine to complete the preparation work before starting the spreading process. Summary of the Invention

[0003] The main technical problem solved by this invention is to provide a low-tension anti-wrinkle fabric laying system that can reduce fabric wrinkles while reducing fabric tension during the laying process, reduce deformation after cutting, and is convenient for single-person operation.

[0004] To solve the above-mentioned technical problems, the present invention provides a low-tension anti-wrinkle fabric laying system, comprising: an unwinding device, a fabric laying device, a fabric laying table, and a central computer. The unwinding device and the fabric laying device are electrically connected to the central computer. The unwinding device includes a frame, a loading seat, an unwinding mechanism, a front conveyor belt, a loading guide mechanism, a tension adjusting roller, and a steering connecting roller. The loading seat is installed directly in front of the frame, and an unwinding table is provided on the loading seat. The unwinding mechanism includes two unwinding frames mounted opposite each other on the unwinding table, relying on the frame. Two fabric roll clamps are arranged opposite each other on the inner sides of the two unwinding frames, one of which is a short-stroke clamp and the other is a long-stroke clamp. The machine frame includes a long-stroke chuck, and a horizontal drive cylinder is installed inside the frame to drive the long-stroke chuck to reciprocate horizontally. The long-stroke chuck and the short-stroke chuck together form an automatic unwinding position. The front-laying conveyor belt is mounted at the top of the frame with a front-high-rear-low shape. The loading guide mechanism includes a guide plate and a guide cylinder. The width of the guide plate matches the distance between the frame and the fabric laying device. One end of the guide plate is rotatably mounted below the rear end of the front-laying conveyor belt. One end of the guide cylinder is connected to the back of the guide plate, and the other end is connected to the frame. Two hinge seats are symmetrically arranged on the outer center of the guide plate, and a hinge rod is installed on each hinge seat. The tension adjusting roller is installed on the two hinge seats. Between the rods, a steering connecting roller seat is installed at the rear of the frame, flush with the top of the fabric laying device. The steering connecting roller is installed inside the steering connecting roller seat, close to the fabric laying device. The fabric laying device includes a fabric laying machine base, a fabric laying head, and a fabric laying conveyor belt. The central computer is located on one side of the top of the fabric laying machine base, and an alarm is installed on the other side of the top of the fabric laying machine base. A fabric clamping mechanism is also installed on the top of the fabric laying machine base between the alarm and the central computer. The fabric clamping mechanism is arranged perpendicular to the fabric unwinding path. The fabric laying conveyor belt is fitted onto a set of telescopic rollers. One end of the telescopic roller set is connected to the fabric laying head, and the other end is connected to the interior of the fabric laying machine base. A roller set reverse traction mechanism is provided inside the fabric laying machine base. The fabric spreading table is equipped with guide rails on both sides. The fabric spreading machine head is mounted on the fabric spreading table based on the guide rails. When the fabric spreading machine head reciprocates along the guide rails on the fabric spreading table, the roller group reverse traction mechanism moves synchronously, pulling the telescopic roller group to drive the fabric spreading conveyor belt to retract synchronously relative to the fabric spreading machine base. A machine head control screen is installed on one side of the fabric spreading machine head. The machine head control screen is electrically connected to the central computer. A linear guide rail is also installed at the outlet position of the fabric spreading machine head. A cutter assembly is installed on the linear guide rail. A servo motor is installed at one end of the linear guide rail. The servo motor can drive the cutter assembly to reciprocate along the linear guide rail. An auxiliary pressure roller of the machine head driven by a cylinder is installed on the inner side of the linear guide rail.

[0005] In a preferred embodiment of the present invention, the angle between the front conveyor belt and the horizontal plane is 10~30°, and a first pressure roller is also installed at the tail end of the front conveyor belt.

[0006] In a preferred embodiment of the present invention, a recovery motor is installed on the unwinding frame where the short-stroke chuck is located, and the recovery motor can drive the short-stroke chuck to rotate.

[0007] In a preferred embodiment of the present invention, a manual unwinding position is symmetrically provided on the unwinding frame, and an unwinding shaft is placed on the manual unwinding position.

[0008] In a preferred embodiment of the present invention, two sets of unwinding action control buttons with the same function are symmetrically arranged on both sides of the frame.

[0009] In a preferred embodiment of the present invention, the fabric clamping mechanism includes a cylinder bracket, a pressure strip, and two clamping cylinders. The cylinder bracket spans across the fabric unwinding path, and the two clamping cylinders are symmetrically installed at both ends of the same side of the cylinder bracket. The top ends of the telescopic rods of the two clamping cylinders are connected together by the pressure strip. Two pressure roller cylinders are also installed on the cylinder bracket, and the two pressure roller cylinders and the two clamping cylinders are located on opposite sides of the cylinder bracket. The top ends of the telescopic rods of the two pressure roller cylinders are connected to a second pressure roller.

[0010] In a preferred embodiment of the present invention, a fabric motion sensor electrically connected to the central computer is also installed on the top of the fabric laying machine base, and the fabric motion state sensor is installed in front of the fabric clamping mechanism.

[0011] In a preferred embodiment of the present invention, the fabric laying machine base is further provided with a transmission belt auxiliary traction cylinder assembly.

[0012] In a preferred embodiment of the present invention, protective brackets are symmetrically installed on both sides of the front end of the fabric spreading machine head.

[0013] The beneficial effects of this invention are as follows: This invention further optimizes existing automatic fabric spreading machines. On the one hand, it incorporates two flattening steps in the fabric spreading process, with a tension adjusting roller between the two flattening steps. This pre-flattening of the fabric before passing through the tension adjusting roller after unwinding ensures uniform force distribution on the fabric surface when the tension adjusting roller presses down, preventing longitudinal wrinkles. When entering the conveyor belt in subsequent steps, the fabric adheres well to the conveyor belt surface, resulting in greater relative friction. In actual production, the relative movement speed between the conveyor belt and the machine head is controlled by a computer, utilizing friction to meet the fabric conveying purpose, thereby reducing the impact of the machine head's tension on the fabric when it moves. This significantly reduces the internal tension of the fabric during spreading, resulting in a significant reduction in overall deformation during final cutting. It also meets the process requirements for flattening and cutting low-strength, lightweight fabrics. Furthermore, the invention includes an auxiliary guiding mechanism between the unwinding mechanism and the spreading mechanism. This allows only one person to complete all material loading actions on-site before the equipment is started, effectively saving labor time and reducing the overall operational difficulty.

[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0016] Please see Figures 1 to 5 The embodiments of the present invention include: A low-tension anti-wrinkle fabric laying system includes: an unwinding device 1, a fabric laying device 2, a fabric laying table 3, and a central computer 4. The unwinding device 1 and the fabric laying device 2 are both electrically connected to the central computer 4. The unwinding device 1 includes a frame 101, a feeding seat 102, an unwinding mechanism, a front unfolding conveyor belt 1012, a loading guide mechanism, a tension adjusting roller 1010, and a steering connecting roller 1011. The feeding seat 102 is mounted on the... Directly in front of the frame 101, the loading seat 101 is provided with an unwinding table 103. The unwinding table 103 consists of two recessed plates, one of which can move according to the length of the fabric roll. The unwinding mechanism includes two unwinding frames 105 mounted opposite each other on the unwinding table 103, relying on the frame 101. Two fabric roll chucks 106 are arranged opposite each other on the inner sides of the two unwinding frames 105. One fabric roll chuck 106 is a short-stroke chuck, and the other is a long-stroke chuck. The frame 101 is equipped with a horizontal drive cylinder 1015, which drives the long-stroke chuck to reciprocate horizontally. The long-stroke chuck and the short-stroke chuck together form an automatic unwinding position. When loading the fabric roll, the long-stroke chuck is first driven away from the short-stroke chuck to facilitate the placement of the fabric roll. After placement, the long-stroke chuck and the short-stroke chuck are driven to close, lifting the fabric roll upward along the inclined surface of the chuck and separating it from the unwinding table 103. The front unfolding conveyor belt 1012 is installed at the top of the frame 101 with a front-high and rear-low shape. The angle between the front unfolding conveyor belt 1012 and the horizontal plane can be adjusted between 10° and 30° as needed. The tail end of the front unfolding conveyor belt 1012 is also equipped with a first pressure roller 1013, which can adjust the angle according to different fabric types. The first pressure roller is passively rotated when the front unfolding conveyor belt moves to press the fabric surface. The material loading and guiding mechanism includes a guide plate 1014 and a guide cylinder 109. The width of the guide plate 1014 matches the distance between the frame 101 and the fabric laying device. One end of the guide plate 1014 is rotatably mounted below the rear end of the front conveyor belt 1012. One end of the guide cylinder 109 is connected to the back of the guide plate 1014, and the other end is connected to the frame 101. Two hinge seats are symmetrically arranged in the middle of the outer side of the guide plate 1014, and a hinge rod is installed on each hinge seat. The tension adjusting roller 1010 is installed between the two hinge rods. A steering connecting roller seat is also installed at the rear of the frame 101, flush with the top of the fabric laying device. The steering connecting roller 1011 is installed in the steering connecting roller seat, close to the fabric laying device. The fabric laying device includes a fabric laying machine base 202, a fabric laying machine head 201, and a fabric laying conveyor belt 204. The central computer 4 is located on one side of the top of the fabric laying machine base 202. An alarm 2018 is installed on the other side of the top of the fabric laying machine base 202. A fabric clamping mechanism is also installed on the top of the fabric laying machine base 202 between the alarm 2018 and the central computer 4. The fabric clamping mechanism is arranged perpendicular to the fabric unwinding path. The fabric spreading conveyor belt 204 is mounted on a set of telescopic rollers 203. One end of the telescopic rollers 203 is connected to the fabric spreading head 201, and the other end is connected to the fabric spreading machine base 202. The fabric spreading machine base 202 is equipped with a roller group reverse traction mechanism. Guide rails are provided on both sides of the fabric spreading table 3. The fabric spreading head 2013 is mounted on the fabric spreading table 3 along the guide rails. When the fabric spreading head 201 moves telescopically along the guide rails on the fabric spreading table 3, the roller group reverse traction mechanism moves synchronously, pulling the telescopic rollers 203 to drive the fabric spreading conveyor belt 204 relative to the fabric spreading machine. The base 201 extends and retracts synchronously. A machine head control panel 2011 is installed on one side of the fabric spreading head 201. The machine head control panel 2011 is electrically connected to the central computer 4. A linear guide rail 2013 is also installed at the outlet position of the fabric spreading head 201. A cutter assembly 2012 is installed on the linear guide rail 2013. A servo motor is installed at one end of the linear guide rail 2013. The servo motor can drive the cutter assembly 2012 to reciprocate along the linear guide rail 2013. An auxiliary pressure roller 2014 driven by a cylinder is installed on the inner side of the linear guide rail 2013.

[0017] A recovery motor 107 is installed on the unwinding frame 105 where the short-stroke chuck is located. The recovery motor 107 can drive the short-stroke chuck to rotate. In this way, after the fabric is laid out, the recovery motor 107 can drive the fabric roll to rotate and recover the remaining fabric. The unwinding frame 105 is also provided with a manual unwinding position 108. An unwinding shaft 104 is placed on the manual unwinding position 108. In this way, when the strength of the central axis of the fabric roll is poor, the unwinding shaft 104 can be manually inserted and then placed on the manual unwinding position 108 to complete the unwinding action.

[0018] Two sets of unwinding action control buttons 1016 with the same function are symmetrically arranged on both sides of the frame 101, so that on-site personnel can control the unwinding mechanism from both sides. This design can effectively reduce reaction time and losses when an emergency stop is required.

[0019] The fabric clamping mechanism includes a cylinder bracket 205, a pressure strip 209, and two clamping cylinders 207. The cylinder bracket 205 spans across the fabric unwinding path, and the two clamping cylinders 207 are symmetrically installed at both ends of the same side of the cylinder bracket 205. The top ends of the telescopic rods of the two clamping cylinders 207 are connected together by the pressure strip 209. In this way, the clamping cylinders 207 can clamp the fabric during cutting according to the program given by the central computer 4, preventing the fabric from slipping.

[0020] Two pressure roller cylinders 206 are also installed on the cylinder bracket 205. The two pressure roller cylinders 206 and the two clamping cylinders 207 are located on both sides of the cylinder bracket 205, and the top of the telescopic rod of the two pressure roller cylinders 206 is connected to a second pressure roller 208. The reason for setting up pressure roller cylinders is that some fabrics are very soft and require very strict tension during the unwinding process. Therefore, they are prone to swaying when conveyed by the fabric spreading conveyor belt 204. Therefore, by setting up a second pressure roller 208, such fabrics can be pressed tightly onto the fabric spreading conveyor belt 204, making it easier for the subsequent fabric spreading head 201 to clamp and cut them.

[0021] The fabric laying machine base 202 is also equipped with a fabric motion sensor 2016 that is electrically connected to the central computer 4. The fabric motion sensor 2016 is installed in front of the fabric clamping mechanism.

[0022] The fabric spreading machine base 202 is also equipped with a transmission belt auxiliary traction cylinder assembly, which consists of two three-axis cylinders 2017. This assembly assists the fabric spreading machine head 201 and the internal roller group reverse traction mechanism in pulling the fabric spreading conveyor belt 204. The three-axis cylinders forming the transmission belt auxiliary traction cylinder assembly can reduce the resistance of the reverse traction mechanism of the roller group in the fabric spreading machine head and base, and improve the flexibility of the telescopic roller group's movement.

[0023] The fabric spreading head 201 is symmetrically equipped with protective brackets 2015 on both sides of its front end, which can prevent on-site personnel from hitting the shearing assembly of the spreading head during its reciprocating motion, thus preventing equipment damage and personnel injury.

[0024] Before starting the invention, the fabric roll is first placed in the unwinding position. Then, the on-site operator pulls the fabric upward and flattens it initially through the front unfolding conveyor belt 1012. Then, the guide plate 1014 drags the fabric across the gap between the frame 101 and the fabric laying machine base 202. After the direction is adjusted by the turning connecting roller 1011, the fabric reaches the fabric laying conveyor belt 204 and is pressed down by the machine head auxiliary pressure roller 2014 of the fabric laying machine head 201. Then, the guide plate 1014 is reset, and the tension adjusting roller 1010 automatically presses on the fabric. In this way, the fabric is pre-flattened before entering the tension adjusting roller, ensuring uniform force in all directions and preventing localized tightness due to tension. After passing through the tension adjusting roller, the fabric is flatter and adheres better to the surface of the subsequent fabric laying conveyor belt 204. This results in relatively high friction between the flattening conveyor belt and the fabric laying conveyor belt and the fabric when the fabric is fed according to the movement of the machine head, effectively reducing the direct force exerted by the machine head on the fabric. As a result, the fabric is subjected to uniform and stable force in all directions, which significantly reduces deformation during cutting and improves the stability of the pattern. Furthermore, this process incorporates a material loading guide structure, allowing only one operator to complete all actions during loading. In contrast, traditional fabric spreading machines require at least two people to simultaneously pull up the fabric edges from both sides to complete the loading process. Additionally, this invention features a front spreading conveyor belt 1012, which pre-flattens the fabric on the frame 101 before adjusting it via the tension adjusting roller 1010 and feeding it onto the spreading conveyor belt 204. The two conveyor belts operate at synchronized speeds, resulting in significantly more uniform stress on the fabric in all directions compared to traditional fabric spreading machines, and a substantial reduction in overall deformation after cutting.

Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
