Technical Field

[0001] The present application relates to the technical field of fabric handling and acceptance, and in particular to a fabric inspection device. Background Art

[0002] When inspecting fabrics on fabric inspection equipment, thinner fabrics are prone to horizontal shrinkage and wrinkling on the inspection table due to the tension of the winding roller, which increases the probability of fabric defects being obscured, making inspection more difficult, and further leading to missed defects and reduced inspection quality. Summary of the Invention

[0003] In order to fully stretch the fabric conveyed on the inspection table in the horizontal direction and improve the inspection quality, the present application provides a fabric inspection device that adopts the following technical solutions:

[0005] By adopting the above technical solution, the end of the fabric to be inspected is led out from the unwinding roller and passed around the fabric handling guide roller before passing through the fabric inspection ramp and finally being wound up by the fabric guide roller and reeled up by the take-up roller. When the fabric enters the fabric inspection ramp, both sides of the fabric fall onto the conveyor device and are sucked by the conveyor belt on the vacuum table. As the fabric moves upward, due to the inclined arrangement of the two conveyor devices, which are wider at the top and narrower at the bottom, the fabric is stretched laterally by the conveyor device moving diagonally outward during movement, fully expanding the fabric in the horizontal direction, making it easier to expose fabric defects, improving the inspection effect, and ensuring the quality of the fabric after inspection.

[0006] Optionally, when the width of the rolled fabric is less than 160 cm, the relationship between the angle θ and the length L of the fabric inspection ramp is L / tanθ<10, where L is in centimeters.

[0007] By adopting the above technical solution, when the fabric width is less than 160 cm, the relationship between the angle θ and the length L of the fabric inspection ramp satisfies L / tanθ<10, which can ensure that the fabric on the fabric inspection ramp can be fully unfolded and reduce the lateral deviation of the fabric when it moves forward, so that the edge of the material roller after winding is kept neat, thereby improving the winding quality.

[0008] Optionally, a plurality of L-shaped brackets are provided on the back of the fabric inspection ramp, and the L-shaped brackets are connected to the frame through the bottom of the conveying device; a bearing plate is provided on the side of the conveying device, and the bearing plate is connected to the frame.

[0011] By adopting the above technical solution, with the cooperation of the third transmission shaft and multiple bevel gears, the two conveying devices are rotated synchronously to achieve parallel conveying of the two sides of the fabric.

[0012] Optionally, a first transmission wheel is provided at the output end of the first drive motor, the first transmission wheel is transmission-connected to a second transmission wheel, a fourth transmission shaft is provided in the middle of the second transmission wheel, the fourth transmission shaft is connected to one end of the winding roller, and the fourth transmission shaft is transmission-connected to the third transmission shaft.

[0013] By adopting the above technical solution, under the connection of the fourth transmission shaft, the winding roller and the first drive motor are indirectly driven to achieve synchronous operation of the winding roller and the conveying device, which is beneficial to the parallel conveyance of the fabric on the fabric inspection ramp.

[0014] Optionally, the two sides of the discharge roller are respectively rotatably connected to a long side plate, a connecting shaft is provided at the other end of the long side plate, the connecting shaft is provided on the frame, the end of the connecting shaft is connected to a second drive motor, a third drive motor is provided on the upper part of the frame, a first gear is provided at the output end of the third drive motor, and a second gear for engaging the first gear is provided at the end of the discharge roller shaft.

[0015] At present, in order to improve the cloth inspection quality, the fabric is often double-sided inspected to avoid the defects that cannot be found by single-sided inspection. However, the existing cloth inspection device can only perform single-sided cloth inspection. After the front side of the fabric is inspected, the roller needs to be reloaded to inspect the back side of the fabric. The rehandling and winding of the roller not only wastes manpower, but also hinders the continuity of the operation and affects the operation efficiency.

[0016] By adopting the above technical scheme, the second driving motor drives the long side plate to rotate, so that the feeding roller at one end of the long side plate is rotated to the front of the cloth inspection slope, and the back side of the fabric is presented. At this time, the second gear of the feeding roller is meshed with the first gear, and the third driving motor drives the feeding roller to reverse, so that the fabric is rewound to the feeding roller, the back side of the fabric is inspected, and the double-sided cloth inspection function without reloading the roller is realized.

[0017] Optionally, the cloth arranging guide roller comprises a front guide roller and a rear guide roller, and the front guide roller and the rear guide roller are connected to a support on both sides, and the support is arranged between the two long side plates.

[0018] By adopting the above technical scheme, the rear guide roller is used to guide and press the fabric when the front side of the fabric is inspected, so that the fabric is attached to the cloth inspection slope, and the front guide roller is used to tension the fabric when the back side of the fabric is inspected, so that the defects of the fabric are exposed.

[0019] Optionally, a cloth inspection sliding table is arranged on the upper part of the frame and can slide, and when the long side plate is driven by the second driving motor to rotate the feeding roller to the front of the slope surface of the cloth inspection slope, the cloth inspection sliding table slides out and moves to the position between the feeding roller and the cloth inspection slope.

[0020] By adopting the above technical scheme, when the back side of the fabric is inspected, the cloth inspection sliding table slides to the position below the feeding roller and the front guide roller to provide a backing plate, a light source and the like for the back side inspection.

[0021] Optionally, a rack section is arranged on both sides of the cloth inspection sliding table, a third gear is arranged on the frame and is meshed with the rack section, the third gear is arranged on the output end of a fourth driving motor, and the cloth inspection sliding table is arranged in the limiting sliding channel of the frame.

[0022] By adopting the above technical scheme, the cloth inspection sliding table is driven by the fourth driving motor to move on the frame, thereby providing help for the back side inspection.

[0023] Optionally, a beam plate is arranged on the side of the frame away from the cloth inspection slope, and a cloth inspection probe is arranged on the beam plate.

[0024] By adopting the above technical scheme, in addition to the manual cloth inspection, the intelligent automatic cloth inspection probe can be arranged to realize a more efficient cloth inspection process.

[0025] In summary, the present application has at least one of the following beneficial technical effects:

[0026] 1. This application uses a conveying device to absorb and convey both sides of the fabric, which is absorbed by the conveyor belt on the vacuum table. As the fabric moves upward, the two sides of the fabric are pulled by the conveying device moving obliquely outward, and are stretched laterally, so that the fabric is fully expanded in the horizontal direction, making it easier to expose the defects of the fabric, improving the inspection effect, and ensuring the quality of the fabric after inspection.

[0027] 2. This application realizes double-sided inspection of fabrics by making the unwinding roller rotate around the fabric inspection ramp, reducing the second feeding process of the material roller, freeing up manpower and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] Reference Figure 1 and Figure 2 The present invention discloses a fabric inspection device comprising a frame 1, a fabric inspection ramp 2 disposed on the upper inner portion of the frame 1, and a plurality of L-shaped brackets 21 disposed on the back of the ramp 2.

[0037] Reference Figure 1 and Figure 2 A feeding roller 3 is provided in front of the fabric inspection ramp 2. Both sides of the feeding roller 3 are rotatably connected to a long side plate 32. The other end of the long side plate 32 is provided with a connecting shaft 33, which is provided on the frame 1. The end of the connecting shaft 33 is connected to a second drive motor 34. A third drive motor 35 is provided on the upper part of the frame 1. The output end of the third drive motor 35 is provided with a first gear 351. The end of the shaft of the feeding roller 3 is provided with a second gear 31 for engaging with the first gear 351. A fabric guide roller is provided on the frame 1 between the feeding roller 3 and the fabric inspection ramp 2. The fabric guide roller includes a front guide roller 41 and a rear guide roller 42. Both the front guide roller 41 and the rear guide roller 42 are connected to a bracket 43 on both sides. The bracket 43 is provided between the two long side plates 32. A fabric guide roller 5 is provided on the upper side of the fabric inspection ramp 2, and a winding roller 6 is provided below the fabric guide roller 5. When loading the material, the end of the fabric 9 on the unwinding roller 3 to be inspected is led out and passed between the front guide roller 41 and the rear guide roller 42 of the fabric handling guide roller, and then the fabric 9 passes through the fabric inspection ramp 2 and is finally wound up on the winding roller 6 through the fabric guide roller 5.

[0038] Reference Figure 2 The left and right sides of the fabric inspection ramp 2 are respectively provided with a conveying device 7, and a supporting plate 74 is provided on the side of the conveying device 7, and the supporting plate 74 is connected to the frame 1. The conveying device 7 includes a conveyor belt 71, a vacuum table 72, and a driving wheel set 73. The upper surface of the vacuum table 72 is parallel to the slope of the fabric inspection ramp 2 and is in contact with the bottom surface of the upper side belt of the conveyor belt 71. The vacuum table 72 is connected to an external vacuum pump, and the conveyor belt 71 is provided with holes for adsorbing the fabric 9.

[0039] Reference Figure 1 The two conveyor devices 7 are arranged at an angle, wider at the top and narrower at the bottom, so that the conveying direction of the conveyor devices 7 forms an angle θ with the direction of the line connecting the upper and lower ends of the slope of the fabric inspection ramp 2. When the width of the wound fabric 9 is less than 160 cm, the relationship between the angle θ and the length L of the fabric inspection ramp 2 is L / tanθ<10, where L is in centimeters. When the fabric width is less than 160 cm, the relationship between the angle θ and the length L of the fabric inspection ramp 2 satisfies L / tanθ<10. This ensures that the fabric on the fabric inspection ramp 2 is fully unrolled, reduces lateral deviation of the fabric as it advances, keeps the edges of the wound material roller neat, and improves winding quality.

[0040] Reference Figure 3 and Figure 4The drive wheel assembly 73 is disposed inside the endless conveyor belt 71 and is used to drive the conveyor belt 71 to rotate. The drive wheel assembly 73 is connected to a transversely arranged first transmission shaft 751. A first bevel gear 752 is provided at the other end of the first transmission shaft 751. The first bevel gear 752 meshes with a second bevel gear 753. A second transmission shaft 754 is vertically arranged in the middle of the second bevel gear 753.

A first transmission wheel 761 is provided at the output end of the first drive motor 76. The first transmission wheel 761 is transmission-connected to a second transmission wheel 762. A fourth transmission shaft is provided in the middle of the second transmission wheel 762. The fourth transmission shaft is connected to one end of the winding roller 6, and the fourth transmission shaft is transmission-connected to the third transmission shaft 757.

[0041] Reference Figure 1 and Figure 3 A slidable cloth inspection slide 8 is provided on the upper portion of the frame 1. When the long side plate 32, driven by the second drive motor 34, rotates the unloading roller 3 to the front of the slope of the cloth inspection ramp 2, the cloth inspection slide 8 slides out and moves between the unloading roller 3 and the cloth inspection ramp 2. Specifically, rack segments 81 are provided on both sides of the cloth inspection slide 8. A third gear 82 meshing with the rack segment 81 is provided on the frame 1. The third gear 82 is provided at the output end of a fourth drive motor 83. Both sides of the cloth inspection slide 8 are provided in the limit slides provided on the frame 1.

[0042] The implementation principle of a cloth inspection device in the embodiment of the present application is as follows:

[0043] Reference Figure 5 , fabric 9 is inspected from the front. When inspecting the front of fabric 9, when fabric 9 enters the fabric inspection slope 2, both sides of fabric 9 fall on the conveying device 7 and are adsorbed by the conveyor belt 71 on the vacuum table 72. As fabric 9 moves upward, since the two conveying devices 7 are inclined with the upper width being wider and the lower width being narrower, both sides of fabric 9 are stretched laterally during the movement under the pull of the conveying device 7 moving obliquely outward, so that fabric 9 is fully expanded in the transverse direction, making it easier to expose the defects of fabric 9, thereby improving the inspection effect and ensuring the quality of fabric 9 after inspection.

[0044] The back of the fabric 9 is inspected. When most of the fabric 9 is wound onto the winding roller 6, the front of the fabric 9 has been basically inspected. At this time, the remaining section of the fabric 9 still wound on the unwinding roller 3 can be inspected manually, or when the fabric 9 is wound onto the unwinding roller 3 after leaving the factory, a discarded remaining section of the fabric 9 is left, that is, this section is only used for connection and does not need to be inspected.

[0045] Reference Figure 6At this time, the conveying device 7 and the winding roller 6 are controlled to stop moving, and the second drive motor 34 is started to drive the long side plate 32 to rotate, so that the unloading roller 3 at one end of the long side plate 32 rotates to the front of the cloth inspection ramp 2, showing the back of the fabric 9. At this time, the second gear 31 of the unloading roller 3 and the first gear 351, the third drive motor 35 drives the unloading roller 3 to reverse, so that the fabric 9 is rewound back to the unloading roller 3. At the same time, the fourth drive motor 83 drives the cloth inspection slide 8 to move between the unloading roller 3 and the cloth inspection ramp 2, and the back of the fabric 9 is set off as a background or provided with a light source, so as to inspect the back of the fabric 9 that is constantly passing by, and achieve the double-sided cloth inspection function without the need to reload the material roller.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
