Problems solved by technology

[0003] In the above-mentioned detection method, the reading of the projected area is usually obtained by using the grid method, that is, the grid is drawn on the projection surface, and then the number of grids covered by the shadow of the fabric is observed, multiplied by each The area of ​​the square is the projected area; if this method is realized by manual observation, not only the accuracy is very poor, but also the efficiency is extremely low; because the square covered by the perimeter of the shadow can only take an approximate number
Of course, the shadow can also be captured by the camera, and then the projected area can be calculated by the graphics analysis software, but the hardware configuration required by this method is very complicated, especially the graphics analysis module, which is not capable of low-end single-chip microcomputers, so the cost is relatively high
[0004] To make matters worse, the above methods are completely powerless for detecting the dynamic drape of fabrics

Embodiment 1

[0017] figure 1 Shown is the first embodiment of the fabric drape detector, wherein the fabric drape detector includes a fabric tray 1, and the fabric tray 1 is in the shape of a disc.

[0018] The fabric tray 1 and a photovoltaic panel 2 directly below are fixed by a support rod 4; the photovoltaic panels 2 and the fabric tray 1 are parallel to each other. Considering the symmetry, the photovoltaic panel 2 is also preferably in the shape of a wafer.

[0019] Below the photovoltaic panel 2 is an electrical base 21, which contains supporting electronic components of the photovoltaic panel, including an electronic current meter; and the arithmetic module and power supply of the detector.

[0020] A parallel light source 3 is provided above the fabric tray 2, and the parallel light source 3 is fixed to the electrical socket 21 through a support 31. The parallel light generated by the parallel light source 3 is vertically downward as shown by the dashed arrow, and the projection area of...

Embodiment 2

[0026] figure 2 Shown is the second embodiment of the fabric drape detector. The difference from the first embodiment is that a rotary drive device 6 is also provided under the electrical base 21, which may be a motor; the rotary drive device 6 serves as The base of the entire detector is fixed; at this time, the parallel light source 3 is fixed to the rotating drive device 6 through the support 31, and is also fixed; and the fabric tray 1, the photovoltaic panel 2, the electrical seat 21 It is driven by the rotation driving device 6 together; thus, the dynamic drape of the fabric sample 5 can be measured, that is, the drape of the fabric sample 5 in a rotating state; and, during the measurement process, the outstanding advantages are Because the photovoltaic panel 2 and the fabric tray 1 rotate synchronously, the boundary line of the orthographic projection of the fabric sample 5 on the surface of the photovoltaic panel 2 is always at a fixed position on the photovoltaic panel...

Embodiment 3

[0028] image 3 Shown is the third embodiment of the fabric drape detector. The difference from the second embodiment is that the support rod 4 is retractable, and the fabric tray 1 is fixed on the photovoltaic system through the retractable support rod 4 The board 2 is directly above, and the photovoltaic board 2 is provided with a distance measuring head 7 which can measure the distance L between the photovoltaic board 2 and the fabric tray 1, such as a laser distance measuring head.

[0029] In the third embodiment, the calculation module calculates the drape P of the fabric sample 5 as follows: P=k(S 0 -S 1 ) / {[S 0 -I current (S 0 -S 1 ) / I Benchmark ] / L -S 1 }②, where k, / I Benchmark , I current Same as Example One; S 0 , S 1 They are the area of ​​the photovoltaic panel 2 and the fabric tray 1 respectively.

[0030] Example 3 In each measurement, the fabric sample 5 is first covered on the fabric tray 1, and then the height of the fabric tray 1 is adjusted by the retractabl...

Abstract

The invention provides a fabric drapability detector which comprises a fabric tray. The fabric tray is fixed to a photovoltaic board right under the fabric tray. The photovoltaic board is parallel to the fabric tray. A collimated light source is arranged above the fabric tray, collimated light produced by the collimated light source is vertically downward, and a projection area of the collimated light surrounds the photovoltaic board. The photovoltaic board is electrically connected to an operation module. The operation module performs calculation in the following mode: reference current subtracts existing output current of the photovoltaic board to obtain a difference value which is then divided by the reference current to obtain a solution, namely (I reference current-I existing current) / I reference current, and then the solution is divided by an appointed coefficient to obtain the final solution which is output finally. The detector can accurately and quickly detect the fabric drapability and is simple in structure and low in cost.

Description

Technical field [0001] The present invention relates to the field of clothing fabric detection, in particular, to a fabric drape detector. Background technique [0002] In the process of development and material selection of apparel fabrics, it is usually necessary to test all aspects of the properties of the fabric. Among them, the drape test is a more conventional test, especially when making women's shirts, the material selection process must consider the fabric Drape. As for the current fabric drape detection, usually the following method is used to cover a circular fabric of a specified size on a disc, so that the periphery of the fabric sags, and calculate the periphery of the fabric on a plane parallel to the disc. The projected area is to compare the projected area with the area of ​​the disk to determine the drape of the fabric. Of course, the smaller the difference between the projected area and the area of ​​the disk, the better the drape. [0003] In the above detecti...
