Abstract
Description
Technical Field
[0001] The utility model relates to the field of textile equipment, in particular to a cloth inspection device. Background Art
[0002] Cloth inspection is an important link in the textile production process, which involves the piece-by-piece inspection of the appearance quality of grey fabrics. This process is carried out according to the national or industrial standards for grey fabric inspection, aiming to detect fabric surface defects, weaving defects and score them, and at the same time make corresponding marks to indicate repairable or non-repairable defects, and accumulate information on downgrading and one-time downgrading. The automatic cloth inspection machine inspects cloth by relying on the reflection and light guiding action of light sources. The normal cloth inspection speed can reach 120 m / min. It works by means of a terminal control system. The detected defects can be displayed and reported on the screen. It is fast and convenient, can adapt to high-frequency defects or newly-occurring defects that rarely occur and has a memory function, and can calculate and process more defects.
[0003] The basic structure of the cloth inspection machine includes a fabric unwinding mechanism, a dragging mechanism, a rewinding mechanism, a cloth inspection table, a light source, etc. However, during the rewinding process of heavy fabrics, the thickness of the cloth edge is much larger than that of the middle cloth surface, resulting in an arc shape with higher sides (cloth edges) and lower middle (cloth surface). At the same time, since the cloth edge is very narrow, generally only 5-8 mm, a small section of relatively loose winding area will appear at the place connected to the cloth edge, affecting the appearance of the product.
[0004] In view of this, it is necessary to improve the structure of the existing cloth inspection machine to improve the rewinding quality. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a cloth inspection device.
[0006] The technical solution for achieving the object of the present utility model is: a cloth inspection device, which includes a cloth guiding roller assembly, a cloth inspection box, and a winding mechanism sequentially arranged on a frame along the fabric traveling route. The cloth guiding roller assembly includes several cloth guiding rollers arranged before and after the cloth inspection box. A cloth winding frame is movably installed on the frame, and the winding mechanism is installed on the cloth winding frame.

[0008] The cloth inspection device realized by the present utility model is provided with an edge detection mechanism and a transverse movement mechanism. The edge detection mechanism is used to detect the cloth edge and send a signal to the control system at the same time. The control system guides the transverse movement mechanism to drive the cloth coiling rack and the fabric on the cloth coiling rack to move horizontally, so that the cloth edge of the fabric always remains at the required control position for offset coiling, so as to eliminate the tension difference caused by the different thicknesses of the cloth edge and the cloth surface, ensure that the cloth edges of the fabric are staggered and flush, and improve the rewinding quality of the cloth inspection device.

The fourth infrared detecting component 65 includes a fourth infrared emitter 651 and a fourth infrared receiver 652. A detecting component installation groove 611 is formed on the cloth edge detecting bracket 61. The detecting component installation groove 611 is located on the fabric traveling route between the winding mechanism 3 and the cloth inspection box 2. The detecting component installation groove 611 has a groove bottom 6111 and two groove walls 6112. The two groove walls 6112 are oppositely arranged on the front and back sides of the fabric 100. The groove bottom 6111 faces the cloth edge 1001 of the fabric 100. The first infrared detecting component 62, the second infrared detecting component 63, the third infrared detecting component 64, and the fourth infrared detecting component 65 are arranged staggered from near to far along the width direction of the fabric 100. The first infrared detecting component 62 and the second infrared detecting component 63 form a first group of detecting components, and the third infrared detecting component 64 and the fourth infrared detecting component 65 form a second group of detecting components. The first infrared emitter 621, the second infrared emitter 631, the third infrared emitter 641, and the fourth infrared emitter 651 are located on the groove wall 6112 on the front side of the fabric, and the second infrared emitter 631 and the fourth infrared emitter 651 are both close to the side of the cloth inspection box 2. The first infrared receiver 622, the second infrared receiver 632, the third infrared receiver 642, and the fourth infrared receiver 652 are respectively installed on the groove wall 6112 on the back side of the fabric. The first group of detecting components, the second group of detecting components, and the transverse movement mechanism 5 are respectively communicatively connected to a control system (not shown).
[0016] The transverse movement mechanism 5 includes a hydraulic cylinder 51, a connecting plate 52, and a pulley and slide rail assembly 53. One hydraulic cylinder 51 is respectively installed on each of the two sides of the machine frame 10 in the width direction of the fabric 100. Each hydraulic cylinder 51 is located below the coiling mechanism 3. A push rod 511 is installed on the hydraulic cylinder 51. The push rod 511 faces the edge detection mechanism 6 side and the axial direction of the push rod 511 is parallel to the width direction of the fabric 100. One end 521 of the connecting plate 52 is fixedly connected to the push rod 511, and the other end 522 of the connecting plate 52 is fixedly connected to the bottom of the cloth winding rack 4. The pulley and slide rail assembly 53 is respectively installed on the side where each hydraulic cylinder 51 is located.

[0017] During operation, the fabric 100 is pulled by the cloth guiding roller 11 to the fabric inspection box 2 for fabric inspection, and then is pulled by the cloth guiding roller 11 and the cloth spreading roller 7 to the coiling mechanism 3 for coiling. During this process, the fabric will pass through the edge detection mechanism 6. The control system sets the first group of detection components and the second group of detection components to open and close alternately. During this process, when the cloth edge is between the two infrared detection components of any group of detection components, the cloth edge is in a flat state that does not require deviation correction: In the initial state, the cloth edge of the fabric is at Figure 4 the first position shown in the figure.

At this time, since the first group of detection components is completely covered by the fabric 100, the first group of detection components sends a signal to the control system, and the control system issues an instruction to guide the push rod 511 of the hydraulic cylinder 51 to retract, driving the fabric 100 to move horizontally until the cloth edge 1001 is at Figure 5 the second position shown in the figure. At this time, the cloth edge is between the first infrared detection component 62 and the second infrared detection component 63; then the first group of detection components is closed, and at the same time the second group of detection components is opened. At this time, the second detection component is not covered by the fabric, and the second detection component sends a signal to the control system. The control system issues an instruction to guide the push rod 511 of the hydraulic cylinder 51 to extend, driving the fabric 100 to move horizontally until the cloth edge 1001 is at Figure 3until reaching the first position shown, and so on, to achieve the left and right reciprocating movement of the cloth winding rack 4, and further achieve the misaligned winding.
