DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, the front view, rear view and top view of the fully automatic cloth cutting device of the present invention are respectively given, Figures 4 to 7 The three-dimensional diagram of the fully automatic cloth cutting device of the present invention is given. The fully automatic cloth cutting device shown is provided with a defect detection machine 1, a cloth stacking machine 2, a cloth stacking machine 3 and a conveyor 4 in sequence along the processing direction of the cloth. The defect detection machine 1 is used to detect whether there are defects on the passing cloth. The cloth stacking machine 2 stacks the cloth after defect detection into multiple layers. The cloth stacking machine 3 folds the stacked cloth into multiple layers (folded twice), and the folded cloth is transported to the next process via the conveyor 4. The defect detection machine 1 shown is composed of a first frame 5 and a defect detection box 9 arranged on the first frame 5. The defect detection box 9 is provided with a detection device for whether there are defects on the cloth. The cloth stacking machine 2 is a relatively mature equipment, which is used in the current cloth production process.

[0025] The main improvement of the present invention is that a cloth stacking machine 3 is added between the cloth stacking machine 2 and the conveyor 4, and the existing manual folding of cloth is replaced by the cloth stacking machine 3. Fig. 9 As shown, given Figure 5 A partial enlarged view of area B in the middle. Fig.12 A partial schematic diagram of the stacking machine of the present invention is given. The stacking machine shown is composed of a third frame 7, a second belt 28, a displacement rod 29, a pneumatic clamping nozzle 30, a front stacking plate 32, a lifting plate 33, a rear stacking plate 34, a lifting cylinder 36, a left cylinder 37, a right cylinder 38, a second conveyor belt 39 and a second belt driving motor. The third frame 7 plays a fixing and supporting role. The second belt 28 is annular and there are two of them. The two second belts 28 are arranged on both sides of the third frame 7. The second belt driving motor (not shown in the figure) is used to drive the two second belts 28 to rotate synchronously. The two second belts 28 are both fixed with a second fixed seat 31, the displacement rod 29 is arranged along the transverse direction of the third frame 7, and a plurality of pneumatic clamping nozzles 30 are evenly fixed on the displacement rod 29. The two ends of the displacement rod 29 are fixed on the second fixed seat 31. In this way, the two second belts 28 can drive the displacement rod 29 to move during the rotation process, so as to pull the cloth stacked on the stacking machine 2 to the stacking machine 3.

[0026] The front folding plate 32, the lifting plate 33 and the rear folding plate 34 are arranged in sequence from front to back on the third frame 7 in a transverse direction, and a cavity through which the lifting plate 33 passes is formed between the front folding plate 32 and the rear folding plate 34. The outer side of the second belt 28 is provided with a cylinder base fixed on the third frame 7, and the lifting cylinder 36 is fixed on the cylinder base in the form of its telescopic rod facing, and the telescopic rod of the lifting cylinder 36 is connected to the lifting plate 33 to drive the lifting plate 33 to move up and down. The left cylinder 37 and the right cylinder 38 shown are both fixed on the third frame 7, and the left cylinder 37 and the right cylinder 38 drive the front folding plate 32 and the rear folding plate 34 to move respectively to realize the folding of the cloth. The width of the lifting plate 33 is equal to the width of the cloth to be folded into (such as 0.3048m), and the distance between the front folding plate 32 and the rear folding plate 34 is slightly larger than the width of the lifting plate 33 to allow the passage of the folded cloth. The second conveyor belt 39 shown is located below the lifting plate 33. The second conveyor belt 39 is also arranged horizontally. Both ends of the second conveyor belt 39 are rotatably arranged on the third frame 7. The second conveyor motor 40 is fixed on the third frame 7. The second conveyor motor 40 is used to drive the second conveyor belt 39 to rotate so as to transport the cloth folded on the lifting plate 33 out.

[0027] When the lifting cylinder 36 drives the lifting plate 33 to move to the highest point, a second cloth inlet 35 is formed between the plane where the front cloth-folding plate 32 and the rear cloth-folding plate 34 are located and the plane where the lifting plate 33 is located. In the process of clamping the cloth on the cloth-stacking machine 2, the second belt drive motor drives the second belt 28 to rotate, thereby driving the displacement rod 29 and the pneumatic clamping nozzle 30 to pass through the second cloth inlet 35 and move toward the cloth-stacking machine 2. After the pneumatic clamping nozzle 30 clamps the cloth, the displacement rod 29 and the pneumatic clamping nozzle 30 pull the cloth The cloth is laid on the front folding plate 32 and the rear folding plate 34 by moving the lifting cylinder 36; then, the lifting cylinder 36 drives the lifting plate 33 to move downward, so that the lifting plate 33 presses the cloth to fit on the second conveyor belt 39, and then the left cylinder 37 and the right cylinder 38 respectively drive the front folding plate 32 and the rear folding plate 34 to move toward the lifting plate 33 to achieve the double folding of the cloth. For a 6-layer cloth with a width of 1 yard (0.9144m), after two folds, it becomes 18 layers and the width becomes 0.3048m. After folding, the second conveying motor 40 drives the second conveying belt 39 to rotate, and the folded cloth is transported out by relying on the friction between the second conveying belt 39 and the cloth.

[0028] like Fig.10 and Fig.11 As shown, they are given respectively Figure 6 Middle C area and Figure 7The partial enlarged view of the middle D area shows that the conveyor 4 is composed of a fourth frame 8, a third conveyor belt 41, a third conveyor motor 42, a rotating conveyor belt 43, a rotating conveyor motor 44, a rotating base plate 45, a lifting linear motor 46, a rotating servo 47 and a support seat 48. First of all, it should be noted that in order to save site space, the same production line is arranged in a straight line as much as possible, that is, the conveyor 4 shown in the figure has the same conveying direction of the cloth as the defect detection machine 1 and the cloth coding machine 2, but the movement direction of the folded cloth output by the second conveyor belt 39 is perpendicular to the conveying direction of the third conveyor belt 41, which requires a steering operation on the cloth, which is achieved by rotating the conveyor belt 43.

[0029] The third conveyor belt 41 is arranged on the fourth frame 8, and the third conveyor motor 42 is also arranged on the fourth frame 8. The third conveyor motor 42 is used to drive the third conveyor belt 41 to rotate so as to transport the folded cloth. The rotating conveyor belt 43 is arranged between the second conveyor belt 39 and the third conveyor belt 41. The rotating conveyor belt 43 transfers the cloth on the second conveyor belt 39 to the third conveyor belt 41 by turning 90 degrees.

[0030] The rotating conveyor belt 43 shown is arranged on the rotating base plate 45, and the rotating conveyor motor 44 is also arranged on the rotating base plate 45. The rotating conveyor motor 44 is used to drive the rotating conveyor belt 43 to rotate. The lifting linear motor 46 shown is fixed on the third frame 7 in the form of an output shaft facing, the housing of the rotating steering gear 47 is fixed on the output shaft of the lifting linear motor 46, the support seat 48 is fixed on the output shaft of the rotating steering gear 47, and the rotating base plate 45 is fixed on the support seat 48. When the rotating conveyor belt 43 and the second conveyor belt 39 are in the same direction, since the rotating conveyor belt 43 and the second conveyor belt 39 are close to each other, the rotating conveyor belt 43 cannot be directly driven to rotate. It is necessary to use the lifting linear motor 46 to drive the rotating base plate 45 and the rotating conveyor belt 43 to descend to the space area below, and then use the rotating steering gear 47 to drive them to rotate to achieve docking with the third conveyor belt 41. In this way, the rotating conveyor belt 43 can be used to transfer the cloth on the second conveyor belt 39 to the third conveyor belt 41.

[0031] like Figure 8 As shown, given Figure 4A partial enlarged view of the middle A area shows that the cloth-coding machine 2 is composed of a second frame 6 and a cloth-coding mechanism, a first transport mechanism and a holding mechanism arranged on the second frame 6. The second frame 6 plays a fixing and supporting role. The cloth-coding mechanism is composed of a first belt 14, a rotating shaft 15, a first belt motor 16, a flip block 18, an upper wing plate 19 and a lower wing plate 20. There are two first belts 14, and the first belts 14 are annular. The two first belts 14 are arranged on both sides of the second frame 6. The rotating shaft 15 is transversely arranged at the rear end of the second frame 6. The two first belt motors 16 are arranged on both sides of the front end of the second frame 6. Pulleys meshing with the two first belts 14 are arranged at both ends of the rotating shaft 15. Pulleys meshing with the two first belts 14 are fixed on the output shafts of the two first belt motors 16. In this way, the two first belt motors 16 can drive the two first belts 14 to rotate.

[0032] The first fixed seat 17 is fixed on each of the two first belts 14, and the two flip blocks 18 are hinged on the two first fixed seats 17. The upper wing plate 19 and the lower wing plate 20 are arranged parallel to each other, and the two ends of the upper wing plate 19 and the lower wing plate 20 are fixed on the two flip blocks 18, respectively, and a first cloth inlet 21 for cloth to pass through is formed between the upper wing plate 19 and the lower wing plate 20. In this way, when the cloth passes through the first cloth inlet 21, the upper wing plate 19 and the lower wing plate 20 can be driven to reciprocate in the process of the first belt motor 16 driving the first belt 16 to reciprocate, so as to achieve the stacking and lamination of the cloth.

[0033] The first transport mechanism shown is composed of a first transport belt 10, a front belt roller 11, a rear belt roller 12 and a first transport motor 13. The front belt roller 11 and the rear belt roller 12 are rotatably arranged on the front and rear ends of the second frame 6 respectively. The first transport belt 10 is arranged on the front belt roller 11 and the rear belt roller 12. The first transport motor 13 is used to drive the front belt roller 11 to rotate so as to realize the transportation of the cloth.

[0034] The holding mechanism shown is composed of a front pressing plate 22, a rear pressing plate 23, a front support rod 24, a rear support rod 25, a front linear motor 26 and a rear linear motor 27. The front pressing plate 22 and the rear pressing plate 23 are respectively arranged transversely at the front end and the rear end of the second frame 6. Pressing needles are evenly distributed on the lower surfaces of the front pressing plate 22 and the rear pressing plate 23, and the cloth is fixed by the pressing needles. The front pressing plate 22 and the rear pressing plate 23 are respectively fixed on the front support rod 24 and the rear support rod 25. The number of the front linear motor 26 and the rear linear motor 27 shown is two. The two front linear motors 26 are fixed to the two sides of the front end of the second frame 6 with the output shaft facing upward, and the two rear linear motors 27 are fixed to the two sides of the rear end of the second frame 6 with the output shaft facing upward. The two ends of the front support rod 24 are fixed to the output shafts of the two front linear motors 26, and the two ends of the rear support rod 25 are fixed to the output shafts of the two rear linear motors 27. A resistance wire is arranged at the center of the lower surface of the front pressing plate 22 along its length direction, and the resistance wire is used to fuse the cloth whose size meets the requirements.

[0035] In this way, during the reciprocating motion of the upper wing plate 19 and the lower wing plate 20, when the upper wing plate 19 and the lower wing plate 20 drive the cloth to move to the rear end, the rear pressure plate 23 presses and holds the rear edge of the cloth, and then the upper wing plate 19 and the lower wing plate 20 move forward, and when they move to the front end, the front pressure plate 22 extends and holds the front edge of the cloth, and so on and so forth to achieve stacking of multiple layers of cloth.
