Description

Yarn detecting device

The present invention relates to a detecting device, and more particularly to a yarn detecting device.

Traditionally, the yarn count is calculated by the weight method. The method is to measure the length of the yarn by hand, then use the balance to weigh the weight of the yarn, and then substitute the length and weight of the yarn into the formula to obtain the yarn. Line count. The disadvantage of the above method is that the tension cannot be precisely controlled, the length of the sampled yarn is inaccurate due to human variation, and the analyzed count is not accurate.

Furthermore, when the obtained sample is a small cloth sample having a warp and weft length of less than three centimeters, a visual method is adopted for analyzing the yarn count: first, a series of yarns of a known count are collected, according to each The yarn is sorted according to various conditions such as the raw material of the yarn, the spinning method, whether it is dyed by sizing, etc.; when the yarn count of the small cloth sample is to be analyzed, the yarn is first taken out from the small cloth sample, and then The original classification structure, judging the yarn belongs to that category, and then comparing the diameters of the known count yarns with the visual method to obtain the count of the small cloth-like yarn. It can be seen from this that the yarn count analysis method obviously has no accuracy, and the visual comparison analysis is too subjective and has no data basis, so the result is not reliable.

In order to improve the accuracy of the above detection. There is a method for using computer digital image processing technology as a basis for comparison of yarn counts, so that the yarn count can be quickly analyzed. However, in this way, the number of counts of a plurality of yarns is required. According to the input of the computer can be compared, it is not directly from the above visual methods. Moreover, the yarn is often curled by the material or the weave, and the length of the crimped yarn image is not easy to obtain, and thus there are still limitations in this manner.

It is worth mentioning that the yarn detecting device 100 further includes a safety member 140 disposed on the plate member 131a and correspondingly threaded and locked to the driving member 133. Keyhole 133b. Here, the safety member 140 locks the driving member 133 on the plate member 131a along the insertion and removal direction D2, so that the driving member 133 is maintained at the position shown in FIG. 1 (ie, the cutters 135A, 135B are away from the base 110). Or, the driving member 133 is unlocked to the plate member 131a, and the user operates the driving member 133 to perform the cutting action.

On the other hand, referring again to FIG. 1, the driving member 133 of the present embodiment further has a second scale 133c and a second lock attachment 133d, and the sliding cutter 135B has a pointer 135B3 directed to the second scale 133c. The second lock attachment 133d moves on the shaft 133a with the sliding cutter 135B, when When the second lock attachment 133d locks the sliding cutter 135B on the shaft 133a, the distance between the cutters 135A, 135B is equal to the above-described preset length. Conversely, after moving the tool 135B to the desired preset length, the user fixes it with the second lock attachment 133d, and then the drive member 133 can be operated to cut the yarn 200 with the cutters 135A, 135B. The length of the cut yarn is the predetermined length described above.

Figure 5 is a flow chart showing the detection of the yarn, wherein a part of the steps corresponds to the yarn detecting device of Figure 1. Here, the yarn count is taken as a description in accordance with the current fabric test specifications (for example, the test procedure described in the CNS 13752 knitted fabric test method). First, in step S510, a plurality of yarns are taken from the sample, and one of the yarns 200 is fixed between the first jig 121 and the second jig 122 of the yarn detecting device 100. Next, the slider 127 is moved in step S520, and the tension value on the tensiometer 123 is simultaneously monitored to confirm whether the yarn 200 reaches the predetermined tension in step S530; if so, the first lock attachment 126 will slide in step S540. The piece 127 is locked to the first rule 124. Next, the tool 135B is moved in step S550 to bring the relative distance of the cutters 135A and 135B to a predetermined length, and in step S560, the safety member 140 is released and the driving member 133 is operated (for example, the user is allowed to hold the drawing shown in FIG. The handle 134), and the cutters 135A, 135B synchronously cut the sampled yarn having a predetermined length, and then, in step S570, push the drive member 133 back to the original position (as shown in FIG. 1) and use the safety member. The drive member 133 is latched on the plate member 131a. Further, the above S510 to S570 are repeated to confirm whether or not a plurality of sampling yarns having the same predetermined length are obtained in step S580, and after the predetermined number of the yarns are sampled, the weighing is performed in step S590. These yarns are sampled, and finally, at step S600, the yarn count can be calculated from the weight and length detected by the sampled yarns.

Fig. 6 is a schematic view of a yarn detecting device according to another embodiment of the present invention. Here, in order to clearly describe the relationship between the related members, the same components as those of the embodiment shown in Fig. 1 will not be labeled or described.

Referring to FIG. 6, in contrast to the above embodiment, the yarn detecting device 300 further includes a linear slide table 310, a servo motor 320, at least one pneumatic cylinder 330, and a control system 340 electrically connected to the components. The linear slide table 310 is assembled on the driving member 133 for controlling the moving position of the cutter 135B. The servo motor 320 is disposed on the base 110 and coupled to the slider 127 for controlling the moving position of the slider 127. The pneumatic cylinder 330 is coupled to the drive member 133 to drive the cutters 135A, 135B to simultaneously cut the yarn 200. Finally, the above-described members and the tensiometer 123 are electrically connected by a control system 340, and the actions of the respective members are coordinated accordingly. Thus, when the yarn 200 is disposed in the first jig 121 and the second jig 122, the servo motor 320 drives the slider 127 to move to stretch the yarn 200, and simultaneously monitors the tension value of the yarn 200 with the tensiometer 123. When the yarn 200 reaches a predetermined tension, the servo motor 320 stops driving the slider 127. Next, the control system 340 drives the linear slide table 310 according to the predetermined length input by the user to control the pneumatic cylinder 330 to move the drive member 133 after the cutter 135B is moved to the predetermined position, and to cause the cutters 135A, 135B on the drive member 133. The yarn 200 is cut off simultaneously. Accordingly, the yarn detecting device 300 of the present embodiment can perform automated detection and cutting operations.

In summary, in the above embodiment of the present invention, the yarn detecting device By fixing the yarn between the clamp and the dynamometer, the user can move the clamp to stretch the yarn to cut the predetermined length of the yarn with the cutter when the yarn reaches a predetermined tensile force. In addition to directly detecting the characteristic data of the yarn, it is no longer limited by the shape of the yarn and the sampling method. Therefore, the yarn is improved in the detection process by a fixed device and method. Repeatability.
