Embodiment 1

[0034] This embodiment provides an automatic cloth inspection system 100 for self-removing moiré patterns, including: unwinding roller 1, transition roller 2, winding roller 3, cloth 4, camera 5, supplementary light source 6, executive roller mechanism 7, cloth inspection control system8.

[0035] Such as figure 1 As shown, the cloth 4 to be inspected is discharged through the discharge roller 1 and is received by the winding roller 3 . Both the camera 5 and the supplementary light source 6 are arranged on the back of the cloth 4, the camera 5 is used for imaging and shooting of the cloth, and the supplementary light source 6 is used for illuminating the photographed cloth. Camera 5 adopts a high-speed camera to continuously shoot cloth imaging images and transmit each frame of cloth imaging images. The angle formed by the imaging section of the cloth 4 and the horizontal plane (such as figure 1The indicated angle r) is between 45° and 60°. Camera 5 and supplementary light...

Embodiment 2

[0050] In this embodiment, the automatic cloth inspection system for self-removing moiré patterns uses the same reference numerals for the same structures as in Embodiment 1, and corresponding text descriptions are omitted.

[0051] Such as Figure 7a As shown, the difference between this embodiment and Embodiment 1 is that in the automatic cloth inspection system for self-removing moiré in this embodiment, the execution roller mechanism 7' includes: a rotating shaft 75, a roller mounting frame 76, a first The execution roller 77, the second execution roller 78, and the center motor (not shown) that drive the rotating shaft to rotate.

[0052] The roller installation frame 76 is connected to the rotating shaft 75 , and the first actuating roller 77 and the second actuating roller 78 are symmetrically installed on the roller mounting frame 76 with respect to the rotating shaft 75 . After the rotating shaft 75 is driven by the central motor, the drive roller mounting frame 76 r...

Embodiment 3

[0054] In this embodiment, an automatic cloth inspection method for self-removing moiré patterns is provided, which is carried out by using the automatic cloth inspection system for self-removing moiré patterns in the above-mentioned implementation 1 or embodiment 2, and the following steps are followed:

[0055] Step 1: Imaging and shooting the cloth during the conveying process to obtain the imaging image of the cloth.

[0056] Step 2, analyzing whether there are defects in the cloth imaging image.

[0057] Step 3, when there is a defect in the imaging image of the cloth, the action of the execution roller mechanism is controlled to apply tension to the cloth.

[0058] Step 4: Comparing the imaged images of the cloth before and after tension is applied to determine whether the defect is moiré.

[0059] Step 5: Real-time record the cloth imaging image data obtained in step 1, the flaw analysis data obtained in step 2, and the moiré judgment data obtained in step 4.

Abstract

The invention provides an automatic cloth inspection system and method for self-removing moiré patterns. The automatic cloth inspection system for self-removing moiré patterns includes a discharge roller and a winding roller, and the cloth is discharged through the discharge roller and collected by the winding roller. , is characterized in that it also includes: a camera, arranged vertically to the surface of the cloth, for imaging and shooting of the cloth; a supplementary light source, arranged on one side of the camera, for illuminating the cloth to be photographed; Between the roller and the take-up roller and located upstream of the camera, it is used to apply tension to the cloth; the cloth inspection control system is connected to the camera and the execution roller mechanism separately, and controls the action of the execution roller mechanism when there is a defect in the imaging image of the cloth. The invention realizes the automatic elimination or weakening of the moiré pattern in the cloth inspection process by executing the action of the roller mechanism, and detects real fabric defects.

Description

technical field [0001] The invention relates to the technical field of fabric image inspection, in particular to an automatic cloth inspection system and method for self-eliminating moiré patterns. Background technique [0002] The weaving and dyeing industry needs to carry out defect inspection on the produced fabrics to control the quality of the produced fabrics. Since the use of intelligent identification equipment for inspection has higher accuracy and faster efficiency than manual inspection, at present, intelligent identification equipment is mostly used for inspection. The process of intelligent cloth inspection is to first image the fabric, and then judge whether the fabric has defects through the detection of the imaged image. However, the mechanical vibration of the cloth winding machine will inevitably bring about the relative vibration between the fabric and the camera, making the imaged image generate moiré patterns similar to water surface ripples, and the mo...
