[0019] The present invention further increases the function of the production line by providing a hair removal component, thereby preventing the product from being folded with a lot of hair scraps, and further improving the product quality.

[0020] Furthermore, the quality inspection device includes a sorting component and a visual inspection component that are relatively arranged.

[0023] The present invention can improve the sorting efficiency by adding a second conveyor belt.

[0024] In a second aspect, the present invention further provides a method for producing a home textile product, using the above-mentioned home textile product production line, comprising the following steps: S01: The loading vehicle transports the loading rack carrying a stack of products to be folded to a set position; S02: The gripper assembly of the feeding robot moves to both ends of the product to be folded, and after the suction cup of the gripper assembly sucks up the product to be folded, the flexible pneumatic fingers gather inwards to grasp the ends of the product to be folded; S03: The clamping jaw assembly moves vertically upward for a set distance and then moves in the feeding direction to place the end of the product to be folded on the feeding assembly; S04: The loading component clamps the product to be folded and moves horizontally; S05: When the product to be folded moves to the first set position, the ironing board descends to iron, and the product to be folded keeps moving horizontally; S06: When the product to be folded moves to the second set position, the suction cover descends to remove hair, and the product to be folded keeps moving horizontally; S07: When the product to be folded moves to the third set position, the visual inspection component performs full-width inspection on the product to be folded, and the product to be folded keeps moving horizontally. When the loading component moves to the third set position, the inspection is completed, the loading component releases the clamping, and the folded product is placed on the conveyor belt 1 and the conveyor belt 2. When the product is judged to be unqualified, the conveyor belt 1 and the conveyor belt 2 rotate in opposite directions, and the unqualified product enters the recycling box from the gap between the conveyor belt 1 and the conveyor belt 2. When the product is judged to be qualified, the conveyor belt 1 and the conveyor belt 2 rotate in the same direction and continue to convey; S08: The qualified products are moved to the feeding mechanism of the folding machine and enter the folding machine. The folding machine folds the foldable products and then discharges them.

[0025] The present invention lifts the loading robot when loading, which can avoid dragging the loading end of the adjacent lower product compared to direct horizontal movement after clamping, and prevents the end of the lower product from moving and affecting the loading of the lower product.

DETAILED DESCRIPTION

[0038] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent. Specific implementation method 1 like Figure 1 As shown, this specific embodiment provides a home textile product production line, including a folding machine 7, and also includes a loading cart 1, a loading robot 4, a frame 10, a post-processing device 5, a quality inspection device 6 and a loading assembly 8; the loading cart 1 is used to transport the loading rack 2 to the loading position, and the loading rack 2 is used to carry a stack of products to be folded; there are two loading robots 4 relatively arranged, and are respectively located on both sides of the loading position; the frame 10 is arranged in the loading direction of the loading robot 4, and a post-processing device 5 and a quality inspection device 6 are arranged on the upper part of the frame 10, and the post-processing device 5 includes an ironing assembly, and the ironing assembly is close to the loading robot 4; the quality inspection device 6 is located between the post-processing device 5 and the folding machine 7; there are two loading assemblies 8 relatively arranged, and the two loading assemblies 8 are movably arranged on both sides of the frame 10, and the loading assembly 8 can be moved from a position close to the loading robot 4 to a position close to the folding machine 7.

[0040] This specific implementation method integrates multiple processes such as loading, ironing post-processing, quality inspection and folding to improve product quality. It also realizes fully automatic loading through the cooperation of the loading vehicle 1, the loading robot 4 and the loading assembly 8, thereby achieving continuous flow of materials, eliminating process interruptions and stagnation caused by traditional manual handling, improving the production line rhythm, and realizing the leap from "single equipment function optimization" to "full process system-level innovation" in the folding of home textile products. It is particularly suitable for high-end home textile production scenarios with high added value, multiple categories and small batches.

[0041] like Figure 1 and Figure 2As shown, in this specific embodiment, the loading rack 2 often carries a stack of home textile products such as bed sheets and quilt covers. Such products are characterized by soft fabrics and large formats. There is a large friction force between two adjacent layers of products. In the process of the loading robot 4 pulling the loading, it is easy to cause the loading end position of the adjacent lower layer of products to change, affecting the accuracy of the loading robot 4 grabbing the lower layer of products. In order to achieve accurate, smooth and continuous loading, on the one hand, considering the impact of the loading robot 4 on the adjacent lower layer of products when grabbing the products, in this specific embodiment, In the embodiment, the feeding robot 4 includes a six-axis robot arm 401, and the execution end of the six-axis robot arm 401 is provided with a clamping claw assembly, and the clamping claw assembly includes a flexible pneumatic finger 402 and a suction cup module 403, and the suction cup module 403 includes a suction cup, and the flexible pneumatic finger 402 is provided with at least three and surrounds the suction cup. In this specific embodiment, four are provided. Through the synergistic effect of the suction cup module 403 and multiple flexible pneumatic fingers 402, it is possible to realize the feeding of home textile products in a composite form of "adsorption + clamping". First, the lifting of the feeding end of the product is realized by the adsorption effect. It can avoid direct clamping causing wrinkles and gathering at the ends of adjacent products in the lower layer. Since home textile products have a certain air permeability, the reliability of clamping is enhanced by clamping in this specific implementation to avoid falling off. On the other hand, considering the influence of the feeding robot 4 on the adjacent lower layer products during the transportation process of the folded products, in this specific implementation, an anti-belt frame is arranged between the feeding rack 2 and the feeding robot 4. The anti-belt frame is in a door-shaped structure. The anti-belt frame includes a horizontally arranged feeding rod 3. The feeding rod 3 is located at the upper part of the feeding end of the feeding rack 2. After such an arrangement, the feeding robot After the hand 4 clamps the product, it is lifted vertically to a position higher than the feeding rod 3 and then moved horizontally to feed the product. This allows the feeding rod 3 to support the middle position of the product to be folded when the product to be folded moves toward the upper feeding component 8, so that the product always maintains a certain distance from the feeding end of the lower product during the movement, thereby avoiding the movement of the lower product due to the feeding movement of the product, causing the end position of the lower product to move, and affecting the accurate and smooth feeding of the lower product. Through the combined effect of the above two aspects, the impact on the lower product can be avoided, and the displacement of its feeding end can be avoided to affect its own feeding.

[0042] like Figures 3 to 5As shown, as preferably, in this specific embodiment, the loading assembly 8 can adopt the following specific structure: the loading assembly 8 includes a moving seat 801, the moving seat 801 is connected to the frame 10 through a slide rail 9, a pressure rod 11 and a support rod 12 are arranged between the two moving seats 801, and the two ends of the support rod 12 are respectively connected to the moving seat 801 through a connecting plate, and lifting plates are arranged at both ends of the pressure rod 11, and the lifting plates are connected to a lifting cylinder, and the lifting cylinder is arranged on the moving seat 801, so that the pressure rod 11 can move up and down to clamp and release the material, and a photoelectric sensor 1201 is also arranged on the support rod 12. When the end of the product to be folded is located on the support rod 12, the photoelectric sensor 1201 sends a signal, and the pressure rod 11 can be vertically lowered to clamp the loading end of the product; in order to achieve accurate position feedback, the moving seat 80 The feeding motor 802 is connected to the frame 10 through a transmission mechanism. The feeding motor 802 is arranged on the frame 10. The feeding motor 802 adopts a servo motor. The transmission mechanism can adopt a gear rack transmission, a screw transmission, etc. In this specific embodiment, the transmission mechanism adopts a belt transmission mechanism; by adopting the pressure rod 11 and the support rod 12 to support the product to be folded, on the one hand, it can achieve full clamping of the end of the product, so that the product to be folded remains flat, which is convenient for ironing to eliminate wrinkles and quality inspection; on the other hand, it can adapt to the feeding of home textile products of different sizes, and improve the application scope of the production line; further, in order to prevent the product from falling off and enhance the clamping reliability, the cross section of the support rod 12 is a V-shaped structure, and the lower surface of the pressure rod 11 is provided with a V-shaped positioning groove 1101. After clamping, the support rod 12 can extend into the positioning groove 1101.

[0043] like Figure 6 As shown, in this specific embodiment, the ironing assembly can adopt the following specific structure: the ironing assembly includes a supporting plate 504 and an ironing board 502 which are arranged opposite to each other, the supporting plate 504 is arranged horizontally on the frame 10, the ironing board 502 is a hollow structure, the ironing board 502 is connected to a hot steam source through a high-temperature solenoid valve, both ends of the ironing board 502 are respectively arranged on corresponding mounting frames 501, the mounting frames 501 are hoisted and arranged on the upper part of the frame 10, and a lifting mechanism 503 is arranged on the mounting frame 501, and the lifting mechanism 503 is connected to the corresponding end of the ironing board 502, and the lifting mechanism 503 is connected to the corresponding end of the ironing board 502. By setting the ironing board 502 to be liftable and the mounting frame 501 to be hoisted, interference with the pressure rod 11 or the support rod 12 can be avoided, so as to facilitate the movement of the loading assembly 8 for loading; the lifting mechanism 503 can adopt an electric cylinder or a hydraulic cylinder. In this specific embodiment, in order to ensure sensitive response, the lifting mechanism 503 includes a connected cylinder and a lifting plate, the cylinder body of the cylinder is connected to the mounting frame 501, the piston rod of the cylinder is connected to the lifting plate, and the lifting plate is connected to the end of the ironing board 502. When the cylinder is extended, the lifting plate drives the ironing board 502 to descend, and vice versa.

[0044] like Figure 7As shown, since home textile products will produce hair scraps during the production process, in order to further improve product quality, in this specific embodiment, the post-processing device 5 also includes a hair removal component, which includes a second support plate 507 and an adsorption cover 506 that are relatively arranged. The second support plate 507 is horizontally arranged on the frame 10, and the adsorption cover 506 is connected to a fan and a storage box. The fan is used to form a negative pressure in the adsorption cover 506, and the storage box is used to store hair scraps. The two ends of the adsorption cover 506 are respectively arranged on the corresponding mounting frame 501, and the mounting frame 501 is provided with a lifting mechanism 520. 05, the lifting mechanism 2 505 is connected to the end of the corresponding adsorption cover 506, and the structure of the lifting mechanism 2 505 is the same as that of the lifting mechanism 1 503, which will not be repeated here; in order to achieve double-sided hair removal of the product, two adsorption covers 506 are arranged in the front and rear along the product conveying direction, and are separately connected to the corresponding fans through corresponding solenoid valves, and the openings of the adsorption covers 506 are arranged oppositely, and the opening of the rear adsorption cover 506 is arranged upward on the frame 10; further, in order to prevent the backflow of hair debris, orifice plates are arranged at the openings of the adsorption covers 506.

[0045] Since the home textile products such as bed sheets and quilt covers have a large width after being laid flat, when quality inspection (full width quality inspection is required), if the side push method is used to remove unqualified products, on the one hand, a larger push plate is required, and its running stability is poor. On the other hand, a side branch conveying path must be set up to convey unqualified products, which increases the floor space. Therefore, as a preferred method, Figure 8As shown, in this specific embodiment, the quality inspection device 6 includes a sorting component and a visual inspection component 602 that are relatively arranged. The visual inspection component 602 is arranged on a mounting crossbar, and the mounting crossbar is hoisted above the frame 10. The sorting component includes a conveyor belt 603, which is arranged on the frame 10 and located between the slide rails 9 on both sides. The discharge end of the conveyor belt 603 is close to the feeding mechanism of the folding machine 7. A recovery box 604 is arranged at the lower part of the feeding end of the conveyor belt 603 and located inside the frame 10. The conveyor belt 603 can convey along the feeding direction of the feeding component 8 and in the reverse direction. The visual inspection component 602 is arranged at the feeding end of the conveyor belt 603 or at the rear of the feeding end of the conveyor belt 603, and the end of the slide rail 9 is located at the rear of the discharging end of the conveyor belt 603; after such arrangement, when the feeding component 8 moves to the end of the slide rail 9 (the third set position), the product is released on the conveyor belt 603. When it is judged to be unqualified, the conveyor belt 603 rotates in the reverse direction to transport the product to the recycling box 604. When the product is qualified, the conveyor belt 603 rotates forward (the same as the feeding direction of the feeding component 8), and the product enters the folding machine through the feeding mechanism of the folding machine 7. 7 is folded; it can be seen that by controlling the forward and reverse rotation of the conveyor belt 1 603 to realize the conveying and sorting and rejecting of the products, there is no need to arrange a branch conveying path separately, which reduces the space occupation and is very suitable for sorting home textile products such as bed sheets and quilt covers; due to the large size of home textile products, in order to further improve the sorting efficiency, the sorting component also includes a conveyor belt 2 601, which is arranged on the frame 10 behind the conveyor belt 1 603 and between the slide rails 9 on both sides. The conveyor belt 2 601 is close to the discharge end of the post-processing device, and the conveyor belt 2 601 and the conveyor belt 1 60 3 is provided with a gap, the recycling box 604 is arranged at the lower part of the gap, the conveyor belt 601 can convey along the loading direction of the loading component 8, and the visual inspection component 602 is arranged above the conveyor belt 601; when the product is judged to be unqualified, the conveying direction of the conveyor belt 601 is the same as the loading direction of the loading component 8, and at the same time, under the reverse conveying of the conveyor belt 1 603, the technical effect of simultaneously conveying both ends of the product to the middle recycling box 604 is achieved. Compared with the single conveying of the conveyor belt 1 603 (the conveying distance is the length of the entire product), the conveying distance is shortened and the efficiency of sorting and rejecting is improved.

[0046] like Figure 9As shown, in order to further increase the function of the production line, boxing and conveying can be performed. In this specific embodiment, a boxing device 13 is provided at the discharge end of the folding machine 7. The boxing device 13 includes a conveying component 1 1303 and a conveying component 2 1301. The conveying component 2 1301 is located at the discharge end of the folding machine 7. The ends of the conveying components 1303 and 1301 that are close to each other are rotatably provided with a material guide component 1302. The swing plate of the material guide component 1302 is rotatably provided on the outer side of the corresponding conveying component support plate through a pin shaft. The material guide component 1302 is driven by a cylinder to achieve swinging, and a conveying component 3 1304 is arranged at the lower part between the two material guide components 1302, and a packaging box 14 is placed on the conveying component 3 1304, and the conveying component 3 1304 works intermittently; the material guide component 1302 can be an independent conveying mechanism with a motor. In this specific embodiment, the driven roller of the material guide component 1302 is arranged between the corresponding two swing plates, and the material guide component 1302 shares the motor and the conveyor belt with the corresponding conveying component, thereby reducing the manufacturing cost of the equipment and simplifying the structure.

[0047] In this specific embodiment, the loading cart 1 adopts an AGV cart, which can automatically identify the loading position. It is a prior art and its structure and principle are not described in detail; the flexible pneumatic fingers 402 and the suction cup module are both prior art that can be purchased on the market, and its structure and principle are not described in detail; the folding machine 7 is a product purchased on the market, model ZD-3400, and its structure and principle are not described in detail; the visual inspection component 602 is a product purchased on the market, and its structure and principle are not described in detail; this specific embodiment also includes a controller, and the loading cart 1, the loading robot 4, the ironing component, the hair removal component, the visual inspection component 602, the conveyor belt 1 603, the conveyor belt 2 601, the conveying component 1 1303, the conveying component 2 1301, the folding machine 7 and the loading component 8 are all electrically connected to the controller. Specific implementation method 2 This specific embodiment also provides a method for producing a home textile product, using the home textile product production line of specific embodiment 1, comprising the following steps: S01: The loading vehicle 1 transports the loading rack 2 carrying a stack of products to be folded to a set position; S02: The gripper assembly of the feeding robot 4 moves to the two ends of the product to be folded, and after the suction cup of the gripper assembly sucks up the product to be folded, the flexible pneumatic fingers 402 gather inwards and grasp the ends of the product to be folded; S03: The clamping jaw assembly moves vertically upward by a set distance and then moves in the feeding direction, the product to be folded moves across the feeding rod 3, the end of the product to be folded is placed on the feeding assembly 8, and returns to its original position; S04: After the photoelectric sensor 1201 on the support rod 12 senses the product, the pressing rod 11 descends, the loading assembly 8 clamps the product to be folded, and then moves horizontally; S05: When the product to be folded moves to the first set position (located at the discharge end of the ironing assembly), the ironing plate 502 descends to perform ironing, while the product to be folded keeps moving horizontally; S06: When the product to be folded moves to the second set position (located at the discharge end of the rear adsorption cover 506), the front adsorption cover 506 descends, and the two fans start working at the same time to remove hair on both sides, while the product to be folded keeps moving horizontally; S07: When the product to be folded moves to the third set position (the end of the slide rail 9 close to the folding machine 7), the visual inspection component 602 performs full-width inspection on the product to be folded, and the product to be folded keeps moving horizontally. When the loading component 8 moves to the third set position, the inspection is completed, the loading component 8 releases the clamping, and places the folded product on the conveyor belt 1 603 and the conveyor belt 2 601. When the product is judged to be unqualified, the conveyor belt 1 603 and the conveyor belt 2 601 rotate in opposite directions, and the unqualified product enters the recovery box 604 from the gap between the conveyor belt 1 603 and the conveyor belt 2 601. When the product is judged to be qualified, the conveyor belt 1 603 and the conveyor belt 2 601 rotate in the same direction and continue to convey; S08: The qualified products are moved to the feeding mechanism of the folding machine 7 and enter the folding machine 7. The folding machine 7 folds the foldable products and then discharges them to the boxing device 13; S09: The conveying component 2 1301 of the cartoning device 13 conveys the folded product to the conveying component 1 1303, and the conveying component 1 1303 rotates in the same direction. When the product moves to the fourth set position (the set position on the conveying component 1 1303), the conveying component 1 1303 stops rotating, and the two material guide components 1302 both rotate downward, and the product falls into the packaging box 14 on the conveying component 3 1304. When the controller determines that the packaging box 14 is fully loaded, the conveying component 3 1304 moves to convey the fully loaded packaging box 14, and at the same time, another empty packaging box 14 moves to the bottom of the two material guide components 1302 to wait for material.

[0049] This specific implementation method realizes ironing, hair removal and quality inspection of the product before folding, thereby improving product quality, and automatically loads the material throughout the process, thereby saving manual labor and improving production efficiency.

[0050] After adopting the above technical solution, 10 sheets were used for verification, and the average output speed of the sheets was 2 pieces / min~3 pieces / min, which greatly improved the production efficiency. After inspection, the products after ironing were flat without dead folds, and the thread removal rate was as high as 98%, which greatly improved the product quality. The downtime rate of the whole shift was ≤10%, and the production line had high quality and reliability.

[0051] From the above specific implementations, it can be seen that the present invention has the following beneficial effects: 1. Through the cooperation of the feeding vehicle 1, the feeding manipulator 4 and the feeding assembly 8, the post-processing, quality inspection and folding of home textile products are fully automatic, eliminating manual operation and improving operation efficiency. The post-processing device 5 has an ironing function to avoid wrinkles and folding of the product, thereby improving the quality of the product. 2. By adding the suction cup module 403, the home textile products can be loaded in a composite form of "adsorption + clamping". First, the loading end of the product is lifted by adsorption, and then the clamping reliability is enhanced by clamping, so as to avoid direct clamping causing the ends of the adjacent products in the lower layer to wrinkle and gather, thereby affecting the loading of the lower layer products. 3. By setting up the anti-belt frame, the middle part of the product to be folded can be supported when it moves toward the upper material assembly 8, so that the product always keeps a certain distance from the feeding end of the lower product during the movement, so as to avoid the lower product moving due to the movement of the product feeding, causing the end position of the lower product to move, affecting the feeding of the lower product; 4. By using the pressure rod 11 and the support rod 12 to hold the product to be folded, on the one hand, the end of the product can be clamped throughout the process, so that the product to be folded remains flat, which is convenient for ironing to eliminate wrinkles and quality inspection; on the other hand, it can adapt to the feeding of home textile products of different sizes, thereby improving the scope of application of this production line; 5. By setting the V-shaped structure and positioning groove, the clamping force on the end of the folded product can be enhanced to prevent it from falling off under the action of external force; 6. By setting the ironing board 502 to be liftable and the mounting frame 501 to be hoisted, interference with the pressing rod 11 or the supporting rod 12 is avoided, so that the loading assembly 8 is convenient to move and load materials; by setting the hair removal assembly, the function of the production line is further increased, so that the product is prevented from having too much hair when folded, and the product quality is further improved; 7. The products are sorted and transported by the forward and reverse rotation of the conveyor belt 603, without the need to arrange branch transport paths, thus reducing space occupation and making it easier to sort home textile products such as bed sheets and quilt covers; 8. By adding a conveyor belt 601, the sorting efficiency can be improved.
