Detection system and method for recording cloth defect by using cursor

The invention relates to a detection system and a method for recording a fabric defect by using a cursor. The detection system can mark a defect on a cloth through a cursor generator and a camera device for calculation by a computer, thereby producing a瑕疵 Record table.

In recent years, due to the impact of the financial turmoil and changes in the economic environment, people in the purchase of apparel products, in addition to pay attention to the design style of the clothing is accidental, but also its price, durability and even safety aspects (such as: whether the dye contains Chemicals are considered, and therefore, how to strike a balance between production costs and apparel quality to meet the needs of today's consumers has become an important issue for apparel manufacturers to improve. Among them, the production cost of apparel is closely related to its production efficiency. In the process of making the fabric into a piece of clothing, it is most time-consuming to detect whether there is any flaw in the fabric. The purpose of the inspection is to have a flaw on the fabric. The parts of the defects (such as burrs, curls, etc.) are marked to ensure that the fabrics with defects in the subsequent processing operations will be discarded and recycled. Therefore, whether the inspection operation is perfect will affect the clothing most directly. quality.

Generally speaking, in the past, the apparel industry mainly performed the inspection of the fabric by manual means, that is, the inspection personnel must visually find out the defective parts on the fabric (hereinafter referred to as "defects"), and manually record the types of defects. After the position and size, make a record table for reference by subsequent processing personnel. However, the aforementioned method of using human power for detection is not only time consuming, intangible The production cost has been increased, and there are still some problems that are difficult to solve in this detection method.

(1) Insufficient data accuracy: During the inspection process, the inspector must use the ruler tool to manually measure the actual position of each defect on the fabric and record it in the record sheet, which is not only cumbersome, but also requires extreme High proficiency and concentration, therefore, if the inspector's experience is insufficient or the production period is tight, it will be difficult for the inspector to maintain the accuracy of the record (eg, the measured position and actual position) There is an error in the position), which affects the quality of the clothing produced.

(2) Insufficient data perfection: As mentioned above, due to the long execution time of the test, it is difficult for the tester to maintain a high degree of concentration in the case of long-term measurement and recording, so as to take care of all The cloth 瑕疵 makes some of the more subtle defects may be ignored, resulting in insufficient information on the record sheet.

(3) Inconvenience in data management: Since the record is recorded manually, rather than stored electronically in the computer system, the tester is not only unable to be in the first place after the record is completed. It is transmitted to the subsequent processing personnel within the time limit, and it is also impossible to judge whether the defects on the fabric exceed a reasonable range according to a plurality of 瑕疵 record tables, so as to carry out review and improvement on the process.

Therefore, how to design a detection system not only does not need to pass through the inspection personnel, but also manually records the coordinate position of the defect point, and can improve the accuracy and efficiency of the detection, which is an important problem that the present invention is intended to solve here.

In view of the fact that the conventional detection method is too complicated and difficult to balance the accuracy and efficiency, the inventor has finally designed the use of the cursor to record the fabric after many years of practical experience and after many experiments and tests. The detection system and method thereof can improve the efficiency and convenience of the inspection personnel in the detection operation.

In this way, the detecting personnel only need to use the cursor generator when performing the detecting operation of the fabric, and project the light spot one by one to the position on the cloth, and the computer can automatically receive the confirmation message. Recording the coordinate positions of each of the defects one by one greatly improves the efficiency of the inspection operation.

Another object of the present invention is that the computer does not receive the confirmation signal. The computer can temporarily store the image signal transmitted by the camera device as a first image signal; if the computer receives the confirmation signal, the computer can transmit the camera signal according to the confirmation signal. The current image signal is stored as a second image signal, and the second image signal is compared with the first image signal to determine the position of the light spot on the cloth, and then the record is recorded as a defect. And calculate the coordinate position of the defect.

The detecting system 1 can automatically record the coordinate positions of the respective points one by one, and accordingly, the 瑕疵 recording table 122a is created to improve the efficiency of the 瑕疵 detecting operation, and since the 瑕疵 recording table 122a is calculated by the computer 12 Therefore, it not only has excellent precision, but also can be conveniently transmitted to subsequent processing personnel in an electronic manner for subsequent cutting work.

In order to more clearly illustrate the embodiment of the detection system of the present invention, FIG. 3 is taken as an example, and the detection method thereof is explained as follows: (301) The conveying device 11 conveys a cloth to the detection level by a predetermined length. (302) the camera device 13 continuously captures the cloth image in the detection area 100 to sequentially generate an image signal; (303) the camera device 13 transmits the image signal to the a computer 12; (304) the cursor generator 14 projects a light spot 140 onto the cloth C in the detection area 100; (305) in the case where the push switch 141 is pressed, the cursor generator 14 can transmit a confirmation message Go to the computer 12; (306) the processing unit 121 of the computer 12 receives the confirmation message, and according to the confirmation message, project the light spot 140 onto the position on the cloth C, and record it as a defect; (307) the processing The unit 121 calculates a coordinate position of the defect on the cloth C; and (308) the processing unit 121 stores the coordinate position in the storage unit 122 to create a record table 122a.

In addition, referring to Figures 1, 2 and 4A-4C, in the first preferred embodiment of the present invention, the detection system 1 further includes a display 123, which can be connected wirelessly or by wire. The computer 12 is connected to each other and can receive the image signal transmitted by the processing unit 121 of the computer 12 and display it for the inspector to confirm whether the camera 13 correctly captures the image of the light spot 140. In addition, when the confirmation switch 141 is not pressed, the computer 12 can temporarily store the image signal transmitted from the camera 13 as a first image signal (as shown in FIG. 4A, at which point the light spot 140 has not been projected yet. On the fabric C, the spot 140 is not displayed on the display 123, and the confirmation switch 141 is pressed and transmitted. After sending the confirmation signal to the computer 12, the computer 12 can temporarily store the received current image signal as a second image signal (as shown in FIG. 4B, where the position of the light spot 140 is the position of the defect). And comparing the second image signal with the first image signal to find the coordinate position P of the defect.

Further, as shown in FIGS. 1 and 2, one side of the fabric C is provided with a one-foot portion C1 which is disposed along the longitudinal direction of the cloth C to mark the longitudinal length of the cloth C.
