Description

Technical Field

[0001] The invention belongs to the technical field of cloth detection, and in particular relates to a detection device for waterproof industrial cloth. Background Art

[0002] In the preparation process of industrial waterproof cloth, the raw materials are generally warped before weaving. The woven cloth is then coated with a waterproof coating (for example, polyurethane waterproof coating, asphalt-based waterproof coating, epoxy resin waterproof coating, etc.) and then dried and cured.

[0003] Pre-coated fabrics, formed after warping and weaving, require inspection before coating to ensure that their surfaces are free of fuzz and large inter-texture gaps. Because laser scanning or single-sided vision sensors are difficult to detect fuzz on fabric surfaces, conventional methods often involve transporting the fabric and placing it on an inspection board for manual inspection. Repairs to any fuzz and inter-texture gaps are then performed, which is time-consuming and labor-intensive. Summary of the Invention

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] In the description of the embodiments of the present invention, it should be understood that terms such as "up", "down", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0040] In the prior art, because it is inevitable that there may be a certain degree of fuzzing on the surface of the waterproof cloth and large pores in the textile process during the production process of the waterproof cloth, the waterproof cloth is generally transported to the inspection board during inspection. The inspectors observe and determine the problem areas, and repair the fuzzing areas by burning or cutting the fuzzing, and repair the areas with large pores by fiddling, which is relatively labor-intensive and resource-intensive.

[0041] In the process of discovering problem areas, workers need to observe with the naked eye, which is a test of their eyesight and prone to omissions. The existing technology lacks detection equipment that can simultaneously observe the fuzzing and surface porosity conditions. In addition, because waterproof coating needs to be applied later, the common spray marking method cannot be used when marking the waterproof cloth. After marking, the waterproof cloth still needs to be moved to the inspection and repair position area, which requires manual repair. Therefore, laser marking is also not applicable.

[0042] Based on the above, if Figure 1 and Figure 5 As shown, an embodiment of the present invention provides a detection device for waterproof industrial cloth, comprising a first visual sensing component 1, a second visual sensing component 2, a marking component 3 and a transmission component, wherein the transmission component is used to transport the waterproof cloth;

[0043] The transmission member includes a first rotating roller 41, the first visual sensing member 1 is arranged on the side of the first rotating roller 41 for detecting the height of the waterproof cloth, the second visual sensing member 2 is arranged above the first rotating roller 42 for detecting the front of the waterproof cloth, and the marking member 3 is arranged above the transmission member. The marking member 3 is configured to mark abnormal positions on the waterproof cloth detected by the first visual sensing member 1 and / or the second visual sensing member 2.

[0044] The waterproof cloth is transported to the transmission component, and the first visual sensing component 1 is used to detect the fuzz height on the surface of the waterproof cloth transported to the position of the first rotating roller 41 in real time. The second visual sensing component 2 is used to detect the pore size on the surface of the waterproof cloth transported to the position of the first rotating roller in real time. When the first visual sensing component 1 and the second visual sensing component 2 detect a problem that needs to be repaired, the marking component 3 is controlled to mark the problem area. When the staff finds the problem area, they stop the operation of the transmission component and repair the problem area.

[0045] like Figure 2 、 Figure 3 、 Figure 4 and Figure 9 As shown, in a further implementation of this embodiment, the marking member 3 includes a plurality of marking components, and the marking components include two conveyor belts 311 and a plurality of marking patches 312;

[0046] The two conveyor belts 311 are arranged in parallel, and the conveyor belts 311 are connected and driven by a transmission wheel 313. A plurality of limit plates 314 are evenly arranged on the conveyor belt 311, and the limit plates 314 on the two conveyor belts 311 are arranged correspondingly, and the two ends of the marking patch 312 are respectively arranged on the corresponding two limit plates 314.

[0047] In a further implementation of this embodiment, the marking patch 312 includes an adsorption sheet 3121 and a lightweight shell 3122 . The lightweight shell 3122 is disposed on the adsorption sheet 3121 , and a second handle 3123 is disposed on the top of the lightweight shell 3122 .

[0048] At least two transmission wheels 313 are set on each conveyor belt 311. The transmission wheels 313 rotate to drive the conveyor belt 311 to move, and then drive the limiting plate 314 set on the conveyor belt 311 to move downward. When the limiting plate 314 reaches the position of the transmission wheel 313, it will rotate to discharge the marking patch 312 set on the limiting plate 314 and slide it to the position where the waterproof cloth needs to be marked.

[0049] Providing a lightweight shell 3122 on the adsorption sheet 3121 can increase the thickness of the marking patch 312 without increasing the weight as much as possible, so that the marking patch 312 can be removed by subsequent staff for maintenance. Further, providing a second handle 3123 on the lightweight shell 3122 can make it more convenient to remove the marking patch 312 and facilitate operation.

[0050] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8 As shown, in a further implementation of this embodiment, the transmission member further includes a second rotating roller 42, a third rotating roller 43 and an adsorption cloth 44, wherein the second rotating roller 42 is arranged on a side of the first rotating roller 41 away from the first visual sensing member 1, and the second rotating roller 42 is arranged parallel to the first rotating roller 41, and the third rotating roller 43 is arranged below the side of the second rotating roller 42 away from the first rotating roller 41;

[0051] The adsorption cloth 44 is connected to the first rotating roller 41 , the second rotating roller 42 and the third rotating roller 43 respectively to form a closed loop. The adsorption cloth 44 is configured to adsorb the marking patch 312 in the marking component 3 .

[0052] In a further embodiment of this embodiment, the adsorption sheet 3121 is made of an iron sheet, and the adsorption cloth 44 is made of a ferromagnetic cloth;

[0053] Or the material of the adsorption sheet 3121 is a ferromagnetic sheet, the material of the adsorption cloth 44 is an iron sheet, the material of the first rotating roller 41, the second rotating roller 42 and the third rotating roller 43 are ceramic rollers, and the material of the limit plate 314, the transmission belt 311, the transmission wheel 313 and the frame of the marking component 3 must all be selected from materials that cannot be adsorbed by magnets to avoid affecting the marking patch 312.

[0054] The textile cloth enters the transmission component through the first rotating roller 41. When entering the transmission component, the textile cloth is placed on the adsorption cloth 43. It should be noted that the adsorption cloth 43 is made of a flexible sheet with ferromagnetism, which can adsorb the iron-containing marker that slides off the marking component 3 to prevent the marker from moving on the waterproof cloth.

[0055] Of course, the adsorption cloth 43 can also be replaced with a flexible iron sheet, and the marker can be set as a ferromagnetic magnet sheet. However, when using this method, it is necessary to control the materials of the first rotating roller 41, the second rotating roller 42 and the third rotating roller 43 to use non-ferrous materials that cannot be adsorbed by magnets, otherwise the marker may be displaced when passing through the rotating rollers.

[0056] like Figure 6 and Figure 7 As shown, in a further implementation of this embodiment, the first visual sensing component 1 includes a first supporting plate 11 and a plurality of first visual sensors 12, and the plurality of first visual sensors 12 are evenly distributed on the first supporting plate 11. The second visual sensing component 2 includes a second supporting plate 21 and a plurality of second visual sensors 22, and the plurality of second visual sensors 22 are evenly distributed on the second supporting plate 21.

[0057] The first visual sensor 12 and the second visual sensor 22 are both high-sensitivity visual sensors. By arranging multiple first visual sensors 12 and multiple second visual sensors 22 side by side, the defect position can be captured more accurately to determine the required marking location.

[0058] In a further embodiment of this embodiment, the marking member 3 further includes a frame 32, and the plurality of marking components are evenly arranged in the frame 32;

[0059] The marking assembly also includes an opening and closing door 315, which is arranged on the side of the frame 32. One side of the opening and closing door 315 is rotatably connected to the frame 32, and the other side of the opening and closing door 315 is snap-connected to the frame 32. A first handle 316 is provided on the opening and closing door 315.

[0060] In a further implementation of this embodiment, a controller 5 and a control button 6 are further included. The controller 5 is electrically coupled to the first visual sensing component 1, the second visual sensing component 2, the marking component 3, the transmission component and the control button 6 respectively. The control button 6 controls the operation of the transmission component through the controller 5.

[0061] In a further implementation of this embodiment, a limiting shaft 7 is further included. The limiting shaft 7 is disposed below the second rotating roller 42 and is configured to limit the adsorption cloth 44 below.

[0062] When the adsorption cloth 44 is below the first rotating roller 41, the second rotating roller 42 and the third rotating roller 43, it will occupy a large space without a support position. By setting a limit shaft 7, the occupied space can be effectively reduced. In the reduced space, detection devices, alarm devices and other components for the operation of the device can be set to increase space utilization.

[0063] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0064] While the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions, and alterations can be made to the embodiments without departing from the principles and spirit of the invention.

[0065] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the embodiments of the present invention, designs structures and embodiments similar to the technical solution without creatively designing them, they shall fall within the scope of protection of the present invention.
