Description
本發明係關於一種紡織品基重之檢測裝置及檢測方法。 The invention relates to a textile base weight detecting device and a detecting method.
目前在市面上常見的紡織品在生產線上的即時品質檢測係相當重要的，其中，目前常見的紡織品之品質檢測項目包含基重檢測。 At present, the quality inspection of the common textiles on the market is very important. Among them, the common textile quality inspection items include the basis weight detection.
一般來說，基重檢測技術係利用光訊號穿透紡織品之方式來進行。進一步來說，操作者可將紡織品配置在光源與光檢測器之間，當光源所發出的光線穿透紡織品後，其強度會減弱，因此，可藉由光檢測器所感測到的光線之光強度與光線之初始光強度來換算出紡織品之基重。 In general, the basis weight detection technique is performed by means of optical signals penetrating the textile. Further, the operator can arrange the textile between the light source and the photodetector, and when the light emitted by the light source penetrates the textile, the intensity thereof is weakened, so that the light light sensed by the photodetector can be The initial light intensity of the intensity and light is used to convert the basis weight of the textile.
然而，藉由上述方式所換算出來的基重與紡織品的實際基重(如磅量到的重量)之間仍有一定程度的誤差，故無法在生產線中精確地掌握紡織品的基重。 However, there is still a certain degree of error between the basis weight converted by the above method and the actual basis weight of the textile (e.g., the weight to the weight), so that the basis weight of the textile cannot be accurately grasped in the production line.
有鑑於此，本發明之一目的在於降低紡織品的 基重運算值與基重實際值之間的誤差，以提高基重檢測技術的精確度。 In view of this, one of the objects of the present invention is to reduce the textile The error between the calculated value of the basis weight and the actual value of the basis weight to improve the accuracy of the basis weight detection technique.
依據本發明之一實施方式，一種紡織品基重之 檢測裝置包含一光源、一帶通濾鏡模組、一光強度檢測裝置以及一基重運算單元。光源係用以朝紡織品發射一光線。光線具有一初始光強度，且光線之波長係在1990奈米至2200奈米的範圍內。帶通濾鏡模組係用以過濾穿透紡織品後之光線。光強度檢測裝置係用以檢測穿透帶通濾鏡模組後的光線之至少一剩餘光強度。基重運算單元係用以根據剩餘光強度與初始光強度得到紡織品之至少一基重運算值。 According to an embodiment of the present invention, a textile basis weight The detecting device comprises a light source, a band pass filter module, a light intensity detecting device and a basis weight computing unit. The light source is used to emit a light toward the textile. The light has an initial light intensity and the wavelength of the light is in the range of from 1990 nm to 2200 nm. The bandpass filter module is used to filter the light that penetrates the textile. The light intensity detecting device is configured to detect at least one residual light intensity of the light passing through the band pass filter module. The basis weight computing unit is configured to obtain at least one basis weight calculation value of the textile based on the residual light intensity and the initial light intensity.
依據本發明之另一實施方式，一種紡織物基重 之檢測方法包含以下步驟。首先，朝一紡織物發射一光線，此光線具有一初始光強度且波長係在1990奈米至2200奈米的範圍內。接著，過濾穿透紡織品後之光線。然後，檢測過濾後的光線之至少一剩餘光強度。接著，根據初始光強度與剩餘光強度得到紡織品之至少一基重運算值。 According to another embodiment of the present invention, a textile basis weight The detection method includes the following steps. First, a ray is emitted toward a textile having an initial light intensity and a wavelength in the range of from 1990 nm to 2200 nm. Next, the light that penetrates the textile is filtered. Then, at least one residual light intensity of the filtered light is detected. Then, at least one basis weight calculation value of the textile is obtained according to the initial light intensity and the residual light intensity.
承上所述，當採用發光波長在1990奈米至2200 奈米範圍內的光源，並搭配帶通濾鏡模組進一步過濾穿透紡織品後的光線時，可有效降低基重運算值與基重實際值之間的誤差。因此，上述實施方式可提高基重檢測技術的精確度。 According to the above, when the emission wavelength is from 1990 nm to 2200 The light source in the nanometer range, combined with the bandpass filter module to further filter the light passing through the textile, can effectively reduce the error between the calculated value of the basis weight and the actual value of the basis weight. Therefore, the above embodiment can improve the accuracy of the basis weight detection technique.

第1圖繪示依據本發明一實施方式之紡織品基重之檢測裝置的示意圖。如第1圖所示，於本實施方式中， 紡織品基重之檢測裝置包含光源100、帶通濾鏡模組200、光強度檢測裝置300以及基重運算單元400。光源100與帶通濾鏡模組200係配置於紡織品T的相對兩側，其中光源100係用以朝紡織品T發射光線，而帶通濾鏡模組200係用以過濾穿透紡織品T後之光線。光線具有初始光強度，而光線在穿透紡織品T與帶通濾鏡模組200後，初始光強度會減弱成剩餘光強度，光強度檢測裝置300便係用以接收穿透帶通濾鏡模組200後的光線，並檢測此光線之剩餘光強度。基重運算單元400係電性連接於光強度檢測裝置300與光源100，以分別從光強度檢測裝置300與光源100得到光線的剩餘光強度及初始光強度，並可根據剩餘光強度與初始光強度得到紡織品T之基重運算值。 1 is a schematic view of a textile base weight detecting device according to an embodiment of the present invention. As shown in FIG. 1, in the present embodiment, The textile basis weight detecting device includes a light source 100, a band pass filter module 200, a light intensity detecting device 300, and a basis weight computing unit 400. The light source 100 and the band pass filter module 200 are disposed on opposite sides of the textile T, wherein the light source 100 is used to emit light toward the textile T, and the band pass filter module 200 is used to filter through the textile T. Light. The light has an initial light intensity, and after the light penetrates the textile T and the band pass filter module 200, the initial light intensity is reduced to the residual light intensity, and the light intensity detecting device 300 is used to receive the through bandpass filter mode. Groups the light after 200 and detects the residual light intensity of this light. The basis weight computing unit 400 is electrically connected to the light intensity detecting device 300 and the light source 100 to obtain the residual light intensity and the initial light intensity of the light from the light intensity detecting device 300 and the light source 100, respectively, and may be based on the residual light intensity and the initial light. The strength gives the basis weight of the textile T.
理論上，藉由光吸收理論可算出紡織品T的基重。進一步來說，經由光吸收理論可知光線穿透介質時，介質物理性質與吸收之關係式為：
其中，I 0代表介質所接收之光強度，I t 代表穿透介質後之光強度，α代表介質之光吸收係數，x代表介質厚度，c代表介質密度。在本實施方式中，介質為紡織品T。在光強度檢測裝置300涵蓋面積之紡織品T的基重W係如下式所示：
其中，代表紡織品T在光強度檢測裝置300上的涵蓋面積之直徑，D代表紡織品T之密度，h代表紡織品T
的厚度。經由式(1)及式(2)可得：
經由式(2)及式(3)可得：
根據式(4)，可藉由紡織品T所接收到的光強度I 0以及穿透紡織品T後的光強度I t 得到基重W。 According to the formula (4), the basis weight W can be obtained by the light intensity I 0 received by the textile T and the light intensity I t after penetrating the textile T.
雖然理論上利用式(4)可算出紡織品T的基重W。然而實際上，若不採用特定發光波長的光源100並在紡織品T後方配置帶通濾鏡模組200，則利用式(4)所計算出來的基重運算值與紡織品T的基重實際值有一定程度的誤差(誤差超過3%)。對此，發明人經實驗發現，當光源100所發出的光線之波長係在1990奈米至2200奈米的範圍內，且在紡織品T與光強度檢測裝置300之間配置帶通濾鏡模組200時，若將此光線之初始光強度I 0與光強度檢測裝置300所檢測到的光強度I t (亦即，光線穿透紡織品T與帶通濾鏡模組200後的剩餘光強度)帶入上述式(4)中，基重運算單元400得到的基重運算值與紡織品T的基重實際值之間的誤差可有效被降低(誤差低於3%)，從而提升基重檢測技術的精確度。於部份實施方式中，基重運算單元400可由電腦的軟體或硬體來實現。 Although the basis weight W of the textile T can be theoretically calculated using the formula (4). However, in practice, if the light source 100 of a specific light-emitting wavelength is not used and the band-pass filter module 200 is disposed behind the textile T, the basis weight calculated by the formula (4) and the actual value of the basis weight of the textile T are A certain degree of error (error exceeds 3%). In this regard, the inventors have found through experiments that the wavelength of the light emitted by the light source 100 is in the range of from 1990 nm to 2200 nm, and a band pass filter module is disposed between the textile T and the light intensity detecting device 300. At 200 o'clock, if the initial light intensity I 0 of the light and the light intensity I t detected by the light intensity detecting device 300 (that is, the residual light intensity after the light penetrates the textile T and the band pass filter module 200) Bringing into the above formula (4), the error between the basis weight calculation value obtained by the basis weight operation unit 400 and the actual value of the basis weight of the textile T can be effectively reduced (error is less than 3%), thereby improving the basis weight detection technique. The accuracy. In some embodiments, the basis weight computing unit 400 can be implemented by software or hardware of a computer.
值得一提的是，雖然光源100所發出的光線之波長係在特定範圍內(亦即，1990奈米至2200奈米的範圍內)，但由於光線穿透紡織品T後，部份光線之波長會改變， 故本實施方式可藉由帶通濾鏡模組200來濾掉不必要波長的光線，從而提高基重運算值的精確度。另值得一提的是，本說明書全文所載之「一參數係在A至B的範圍內」不僅代表該參數可為大於A且小於B的任意值，也代表該參數可等於A或等於B。於部份實施方式中，紡織品T的基重實際值係指紡織品T經由磅量所得到的值。 It is worth mentioning that although the wavelength of the light emitted by the light source 100 is within a specific range (that is, in the range of 1990 nm to 2200 nm), the wavelength of some rays after the light penetrates the textile T. Will change, Therefore, in this embodiment, the bandpass filter module 200 can filter out light of unnecessary wavelengths, thereby improving the accuracy of the calculation value of the basis weight. It is also worth mentioning that the phrase "a parameter is in the range of A to B" as used throughout this specification not only means that the parameter can be any value greater than A and less than B, but also that the parameter can be equal to A or equal to B. . In some embodiments, the actual basis weight of the textile T refers to the value obtained by the textile T via the pounds.
經實驗發現，當紡織品T所接收到的光線波長 為2050奈米，並搭配後方的帶通濾鏡模組200時，基重運算單元400所得到的基重運算值與紡織品T的基重實際值之間的誤差可進一步被降低。因此，較佳而言，光源100所發射之光線之波長實質上為2050奈米。 It has been found through experiments that the wavelength of light received by textile T When it is 2050 nm and is matched with the rear band pass filter module 200, the error between the basis weight calculation value obtained by the basis weight operation unit 400 and the actual value of the basis weight of the textile T can be further reduced. Therefore, preferably, the wavelength of the light emitted by the light source 100 is substantially 2050 nm.
第2圖繪示依據本發明另一實施方式之紡織品 基重之檢測裝置的示意圖。如第2圖所示，本實施方式與前述實施方式之間的主要差異係在於帶通濾鏡模組200a包含第一帶通濾光片210、第二帶通濾光片220與第三帶通濾光片230，依序沿著光源100往光強度檢測裝置300的方向排列。因此，當光源100發光時，第一帶通濾光片210可過濾穿透紡織品T後之光線，第二帶通濾光片220可過濾穿透第一帶通濾光片210後之光線，而第三帶通濾光片230可過濾穿透第二帶通濾光片220後之光線。第二帶通濾光片220之最低可通過波長係大於第一帶通濾光片210之最低可通過波長，並小於第三帶通濾光片230之最低可通過波長。藉由這些帶通濾光片過濾穿透紡織品T後的光線，可有效地降低基重運算值與基重實際值之間的誤差。 2 is a view showing a textile according to another embodiment of the present invention. Schematic diagram of the detection device of the basis weight. As shown in FIG. 2, the main difference between the present embodiment and the foregoing embodiment is that the band pass filter module 200a includes a first band pass filter 210, a second band pass filter 220, and a third band. The pass filter 230 is sequentially arranged along the light source 100 in the direction of the light intensity detecting device 300. Therefore, when the light source 100 emits light, the first band pass filter 210 can filter the light that penetrates the textile T, and the second band pass filter 220 can filter the light that passes through the first band pass filter 210. The third band pass filter 230 filters the light that passes through the second band pass filter 220. The lowest passable wavelength of the second band pass filter 220 is greater than the lowest passable wavelength of the first band pass filter 210 and less than the lowest passable wavelength of the third band pass filter 230. By filtering the light passing through the textile T by these band pass filters, the error between the calculated value of the basis weight and the actual value of the basis weight can be effectively reduced.
於部份實施方式中，第一帶通濾光片210之最低可通過波長實質上為1020奈米，第二帶通濾光片220之最低可通過波長實質上為1550奈米，第三帶通濾光片230之最低可通過波長實質上為1730奈米。值得一提的是，本說明書全文所述之「帶通濾光片之最低可通過波長實質上為A奈米」仍允許微量波長低於A奈米的光線穿透該帶通濾光片。 In some embodiments, the lowest passable wavelength of the first band pass filter 210 is substantially 1020 nm, and the lowest passable wavelength of the second band pass filter 220 is substantially 1550 nm, the third band The minimum passable wavelength of the pass filter 230 is substantially 1730 nm. It is worth mentioning that the "minimum passable wavelength of the bandpass filter is substantially A nanometer" as described throughout the specification still allows light of a trace wavelength lower than A nanometer to penetrate the band pass filter.
藉由採用上述三種帶通濾光片並搭配發光波長為2050奈米之光源100，可更進一步地降低基重運算值與基重實際值之間的誤差。以下將以各種不同紡織品T的實驗數據佐證上述實施方式可有效降低基重運算值與基重實際值之間的誤差。 By using the above three band pass filters in combination with the light source 100 having an emission wavelength of 2050 nm, the error between the calculated value of the basis weight and the actual value of the basis weight can be further reduced. The experimental data of various textiles T will hereinafter prove that the above embodiment can effectively reduce the error between the calculated value of the basis weight and the actual value of the basis weight.
上述表一係以已上膠之聚脂纖維(polyester)做為紡織品，並羅列了28種不同顏色之已上膠聚脂纖維的基重運算值、基重實際值以及誤差。由表一可知，當光源100之發光波長為2050奈米，並搭配最低可通過波長實質上為1020奈米之第一帶通濾光片210，最低可通過波長實質上為1550奈米之第二帶通濾光片220以及最低可通過波長實質上為1730奈米之第三帶通濾光片230時，針對上述各種顏色之聚脂纖維所得到的基重運算值與對應基重實際值之間的誤差大部分係小於3%，從而有效提高基重運算值的精確度。 The above table 1 uses the sized polyester as the textile, and lists the basis weight calculation value, the actual value of the basis weight and the error of the sized sized polyester fibers of 28 different colors. As can be seen from Table 1, when the light source 100 has an emission wavelength of 2050 nm and is matched with a first passband filter 210 having a minimum wavelength of 1020 nm, the minimum passable wavelength is substantially 1550 nm. When the two band pass filter 220 and the third band pass filter 230 having a minimum passable wavelength of substantially 1730 nm, the basis weight calculated value and the corresponding base weight actual value obtained for the polyester fibers of the above various colors are obtained. Most of the errors are less than 3%, which effectively improves the accuracy of the basis weight calculation value.
於表一中，每一種顏色的已上膠聚脂纖維係做了5次剩餘光強度的檢測，並利用這5個剩餘光強度檢測值的平均值做為前述式(4)之剩餘光強度I t ，而得到基重W的運算值。 In Table 1, the varnished polyester fiber of each color was tested for 5 times of residual light intensity, and the average value of the detected values of the five remaining light intensities was used as the residual light intensity of the above formula (4). I t , and the calculated value of the basis weight W is obtained.
下表記載了係上述聚脂纖維在未上膠時所得到 的實驗結果。 The following table shows that the above polyester fibers are obtained when not sized. Experimental results.
上述表二係以表一所用之聚脂纖維未上膠時所 得到的基重運算值、基重實際值以及誤差。由表二可知，當光源100之發光波長為2050奈米，並搭配最低可通過波長實質上為1020奈米之第一帶通濾光片210，最低可通過波長實質上為1550奈米之第二帶通濾光片220以及最低可通過波長實質上為1730奈米之第三帶通濾光片230時，針對上述各種顏色之未上膠聚脂纖維所得到的基重運算值與對應基重實際值之間的誤差大部分係小於3%，從而有效提高基重運算值的精確度。 The above table 2 is when the polyester fiber used in Table 1 is not glued. The calculated basis weight value, the base weight actual value, and the error. As can be seen from Table 2, when the light source 100 has an emission wavelength of 2050 nm and is matched with a first passband filter 210 having a minimum wavelength of 1020 nm, the minimum passable wavelength is substantially 1550 nm. When the two-band pass filter 220 and the third band pass filter 230 having a minimum passable wavelength of substantially 1730 nm, the basis weight calculation value and the corresponding base obtained for the un-sized polyester fibers of the above various colors are used. The error between the actual values is mostly less than 3%, which effectively improves the accuracy of the basis weight calculation value.
值得一提的是，藉由表一及表二可精確地得到同一紡織品(如同色的聚脂纖維)在未上膠時與上膠後的基重運算值。因此，可藉由比較未上膠時的基重運算值與上膠後的基重運算值，來得到該紡織品的上膠重量，從而檢測上膠機台的上膠量是否準確。 It is worth mentioning that, by Tables 1 and 2, the basis weight of the same textile (like the colored polyester fiber) when not being glued and after the sizing is accurately obtained. Therefore, the sizing weight of the textile can be obtained by comparing the calculated value of the basis weight when the sizing is not performed and the calculated value of the basis weight after sizing, thereby detecting whether the sizing amount of the sizing machine is accurate.
於表二中，每一種顏色的未上膠聚脂纖維係做了5次剩餘光強度的檢測，並利用這5個剩餘光強度檢測值的平均值做為前述式(4)之剩餘光強度I t ，而得到基重W的運算值。 In Table 2, the uncoated polyester fiber of each color was tested for 5 times of residual light intensity, and the average value of the detected values of the five remaining light intensities was used as the residual light intensity of the above formula (4). I t , and the calculated value of the basis weight W is obtained.
下表記載了比前述已上膠聚脂纖維更重的已上膠聚脂纖維的實驗結果。 The table below reports the results of experiments on sized sizing polyester fibers that are heavier than the previously sized sizing polyester fibers.
上述表三係以另一種較重之已上膠聚脂纖維做為紡織品，並羅列了28種不同顏色之已上膠聚脂纖維的基重運算值、基重實際值以及誤差。由表三可知，即使檢測更重的已上膠聚脂纖維，只要當光源100之發光波長為2050奈米，並搭配最低可通過波長實質上為1020奈米之第一帶通濾光片210，最低可通過波長實質上為1550奈米之第二帶通濾光片220以及最低可通過波長實質上為1730奈米之第三帶通濾光片230時，針對上述較重之已上膠聚脂纖維所得到的基重運算值與對應基重實際值之間的誤差大部分仍係小於3%，從而有效提高基重運算值的精確度。 The above table III uses another heavier sized sizing polyester fiber as the textile, and lists the base weight calculation value, the actual value of the basis weight and the error of the sized sized sizing polyester fibers of 28 different colors. As can be seen from Table 3, even if the heavier sized sized polyester fiber is detected, as long as the light source 100 has an emission wavelength of 2050 nm and is matched with the first passband filter 210 having a minimum passable wavelength of substantially 1020 nm. The lowest passable sizing can be achieved by passing the second band pass filter 220 having a wavelength of substantially 1550 nm and the third band pass filter 230 having a minimum passable wavelength of substantially 1730 nm. The error between the calculated value of the basis weight obtained by the polyester fiber and the actual value of the corresponding basis weight is still less than 3%, so that the accuracy of the calculated value of the basis weight is effectively improved.
於表三中，每一種顏色的已上膠聚脂纖維係做了5次剩餘光強度的檢測，並利用這5個剩餘光強度檢測值的平均值做為前述式(4)之剩餘光強度I t ，而得到基重W的運算值。 In Table 3, the varnished polyester fiber of each color was tested for 5 times of residual light intensity, and the average value of the detected values of the five remaining light intensities was used as the residual light intensity of the above formula (4). I t , and the calculated value of the basis weight W is obtained.
下表記載了表三所用之聚脂纖維未上膠時所得 到的實驗結果。 The following table shows the results obtained when the polyester fibers used in Table 3 are not glued. The experimental results.
上述表四係以表三所用之聚脂纖維未上膠時所 得到的基重運算值、基重實際值以及誤差。由表四可知，當光源100之發光波長為2050奈米，並搭配最低可通過波長實質上為1020奈米之第一帶通濾光片210，最低可通過波長實質上為1550奈米之第二帶通濾光片220以及最低可通過波長實質上為1730奈米之第三帶通濾光片230時，針對上述各種顏色之未上膠聚脂纖維所得到的基重運算值與對應基重實際值之間的誤差大部分係小於3%，從而有效提高基重運算值的精確度。 Table 4 above is the time when the polyester fiber used in Table 3 is not glued. The calculated basis weight value, the base weight actual value, and the error. As can be seen from Table 4, when the light source 100 has an emission wavelength of 2050 nm and is matched with a first passband filter 210 having a minimum wavelength of 1020 nm, the minimum passable wavelength is substantially 1550 nm. When the two-band pass filter 220 and the third band pass filter 230 having a minimum passable wavelength of substantially 1730 nm, the basis weight calculation value and the corresponding base obtained for the un-sized polyester fibers of the above various colors are used. The error between the actual values is mostly less than 3%, which effectively improves the accuracy of the basis weight calculation value.
值得一提的是，藉由表三及表四可精確地得到同一紡織品(如同色的聚脂纖維)在未上膠時與上膠後的基重運算值。因此，可藉由比較未上膠時的基重運算值與上膠後的基重運算值，來得到該紡織品的上膠重量，從而檢測上膠機台的上膠量是否準確。 It is worth mentioning that, by Tables 3 and 4, the basis weight of the same textile (like the colored polyester fiber) when not being glued and after the sizing is accurately obtained. Therefore, the sizing weight of the textile can be obtained by comparing the calculated value of the basis weight when the sizing is not performed and the calculated value of the basis weight after sizing, thereby detecting whether the sizing amount of the sizing machine is accurate.

上述表五係以已上膠之尼龍(nylon)做為紡織品，並羅列了28種不同顏色之已上膠尼龍的基重運算值、基重實際值以及誤差。由表五可知，當光源100之發光波長為2050奈米，並搭配最低可通過波長實質上為1020奈米之第一帶通濾光片210，最低可通過波長實質上為1550奈米之第二帶通濾光片220以及最低可通過波長實質上為1730奈米之第三帶通濾光片230時，針對上述各種顏色之已上膠尼龍所得到的基重運算值與對應基重實際值之間的誤差大部 分係小於3%，從而有效提高基重運算值的精確度。 The above table 5 is a stenciled nylon (nylon) as a textile, and lists the base weight calculation value, the base weight actual value and the error of 28 different colors of the sized nylon. As can be seen from Table 5, when the light source 100 has an emission wavelength of 2050 nm and is matched with a first passband filter 210 having a minimum wavelength of 1020 nm, the minimum passable wavelength is substantially 1550 nm. When the two-band pass filter 220 and the third band pass filter 230 having a minimum passable wavelength of substantially 1730 nm, the basis weight calculation value and the corresponding basis weight obtained for the above-mentioned various colors of the sized nylon are actually obtained. Most of the error between values The division is less than 3%, which effectively improves the accuracy of the calculation of the basis weight.
於表五中，每一種顏色的已上膠尼龍係做了5次剩餘光強度的檢測，並利用這5個剩餘光強度檢測值的平均值做為前述式(4)之剩餘光強度I t ，而得到基重W的運算值。 In Table 5, the varnished nylon of each color is tested for 5 residual light intensities, and the average value of the five remaining light intensity detection values is used as the residual light intensity I t of the above formula (4). And the calculated value of the basis weight W is obtained.
下表記載了係上述尼龍在未上膠時所得到的實驗結果。 The following table describes the experimental results obtained when the above nylon is not sized.
上述表六係以表五所用之尼龍未上膠時所得到的基重運算值、基重實際值以及誤差。由表六可知，當光源100之發光波長為2050奈米，並搭配最低可通過波長實質上為1020奈米之第一帶通濾光片210，最低可通過波長實質上為1550奈米之第二帶通濾光片220以及最低可通過波長實質上為1730奈米之第三帶通濾光片230時，針對上述各種顏色之未上膠尼龍所得到的基重運算值與對應基重實際值之間的誤差大部分係小於3%，從而有效提高基重運算值的精確度。 The above table 6 is the basis weight calculation value, the base weight actual value and the error obtained when the nylon used in Table 5 is not sized. It can be seen from Table 6 that when the light source 100 has an emission wavelength of 2050 nm and is matched with a first passband filter 210 having a minimum wavelength of 1020 nm, the minimum passable wavelength is substantially 1550 nm. When the two band pass filter 220 and the third band pass filter 230 having a minimum passable wavelength of substantially 1730 nm, the basis weight calculation value and the corresponding basis weight obtained for the uncolored nylon of the above various colors are actually Most of the errors between the values are less than 3%, which effectively improves the accuracy of the basis weight calculation value.
值得一提的是，藉由表五及表六可精確地得到同一紡織品(如同色的尼龍)在未上膠時與上膠後的基重運算值。因此，可藉由比較未上膠時的基重運算值與上膠後的基重運算值，來得到該紡織品的上膠重量，從而檢測上膠機台的上膠量是否準確。 It is worth mentioning that, by Tables 5 and 6, the basis weight of the same textile (like colored nylon) can be accurately obtained when it is not glued and after the glue is applied. Therefore, the sizing weight of the textile can be obtained by comparing the calculated value of the basis weight when the sizing is not performed and the calculated value of the basis weight after sizing, thereby detecting whether the sizing amount of the sizing machine is accurate.
於表六中，每一種顏色的未上膠尼龍係做了5次剩餘光強度的檢測，並利用這5個剩餘光強度檢測值的平均值做為前述式(4)之剩餘光強度I t ，而得到基重W的運算值。 In Table 6, the uncoated nylon of each color was tested for 5 times of residual light intensity, and the average value of the detected values of the five remaining light intensities was used as the residual light intensity I t of the above formula (4). And the calculated value of the basis weight W is obtained.
由以上六個表的實驗結果可知，當光源100之 發光波長為2050奈米，並搭配最低可通過波長實質上為1020奈米之第一帶通濾光片210，最低可通過波長實質上為1550奈米之第二帶通濾光片220以及最低可通過波長實質上為1730奈米之第三帶通濾光片230時，基重運算單元400所得到的基重運算值與基重實際值之間的誤差可有效降低，從而提高基重檢測的精確度。 From the experimental results of the above six tables, it can be known that when the light source 100 The emission wavelength is 2050 nm, and the first band pass filter 210 with a minimum passable wavelength of 1020 nm is adopted, and the second band pass filter 220 having a wavelength of substantially 1550 nm and the lowest pass can be used. When the third band pass filter 230 having a wavelength of substantially 1730 nm can be passed, the error between the calculated value of the basis weight calculated by the basis weight operation unit 400 and the actual value of the basis weight can be effectively reduced, thereby improving the basis weight detection. The accuracy.
於部份實施方式中，第二帶通濾光片220與第三帶通濾光片230的最低可通過波長分別不限於1550奈米與1730奈米，但兩者仍均大於第一帶通濾光片210的最低可通過波長(1020奈米)。於部份實施方式中，第一帶通濾光片210的最低可通過波長並不限於1020奈米，但仍係小於第二帶通濾光片220的最低可通過波長(1550奈米)，另外，第三帶通濾光片230的最低可通過波長並不限於1730奈米，但仍係大於第二帶通濾光片220的最低可通過波長(1550奈米)。於部份實施方式中，第一帶通濾光片210與第二帶通濾光片220之最低可通過波長分別不限於1020奈米與1550奈米，但兩者仍均小於第三帶通濾光片230的最低可通過波長(1730奈米)。 In some embodiments, the minimum passable wavelengths of the second band pass filter 220 and the third band pass filter 230 are not limited to 1550 nm and 1730 nm, respectively, but both are still greater than the first band pass. The lowest pass wavelength (1020 nm) of the filter 210. In some embodiments, the minimum passable wavelength of the first band pass filter 210 is not limited to 1020 nm, but is still less than the lowest passable wavelength (1550 nm) of the second band pass filter 220. In addition, the lowest passable wavelength of the third band pass filter 230 is not limited to 1730 nm, but is still greater than the lowest passable wavelength (1550 nm) of the second band pass filter 220. In some embodiments, the minimum passable wavelengths of the first band pass filter 210 and the second band pass filter 220 are not limited to 1020 nm and 1550 nm, respectively, but both are still smaller than the third band pass. The minimum passable wavelength of the filter 230 (1730 nm).
於部份實施方式中，如第2圖所示，檢測裝置還包含第一雙凸透鏡510以及第二雙凸透鏡520。第一雙凸透鏡510係位於帶通濾鏡模組200a與光源100之間，第二雙凸透鏡520係位於帶通濾鏡模組200a與光強度檢測裝置300之間。在使用時，紡織品T可位於第一雙凸透鏡510與第二雙凸透鏡520之間，如此一來，第一雙凸透鏡510可將光源 100之放射光線收斂至紡織品T，而第二雙凸透鏡520可將穿過紡織品T與帶通濾鏡模組200a後的光線收斂至光強度檢測裝置300。 In some embodiments, as shown in FIG. 2, the detecting device further includes a first lenticular lens 510 and a second lenticular lens 520. The first lenticular lens 510 is located between the band pass filter module 200a and the light source 100, and the second lenticular lens 520 is located between the band pass filter module 200a and the light intensity detecting device 300. In use, the textile T can be located between the first lenticular lens 510 and the second lenticular lens 520, such that the first lenticular lens 510 can be the light source The radiation of 100 converges to the textile T, and the second lenticular lens 520 converges the light passing through the textile T and the bandpass filter module 200a to the light intensity detecting device 300.
第3圖繪示依據本發明另一實施方式之紡織品基重之檢測裝置的示意圖。如第3圖所示，本實施方式與前述實施方式之間的主要差異係在於：本實施方式之檢測裝置還包含光強度標準差運算單元600以及校正單元700。光強度標準差運算單元600係用以根據複數剩餘光強度得到至少一光強度補償標準差。校正單元700係耦合於光強度標準差運算單元600，而用以根據剩餘光強度、初始光強度與光強度補償標準差得到紡織品T之已校正基重運算值。藉由此校正手段，可確保已校正基重運算值更收斂於基重實際值，而降低誤差並提高基重檢測的精確度。 3 is a schematic view of a textile base weight detecting device according to another embodiment of the present invention. As shown in FIG. 3, the main difference between the present embodiment and the foregoing embodiment is that the detection device of the present embodiment further includes a light intensity standard deviation calculation unit 600 and a correction unit 700. The light intensity standard deviation computing unit 600 is configured to obtain at least one light intensity compensation standard deviation according to the plurality of residual light intensities. The correction unit 700 is coupled to the light intensity standard deviation operation unit 600 for obtaining the corrected basis weight calculation value of the textile T according to the residual light intensity, the initial light intensity and the light intensity compensation standard deviation. By means of this correction, it is ensured that the corrected basis weight operation value converges more to the base weight actual value, and the error is reduced and the accuracy of the basis weight detection is improved.
具體來說，發明人將式(3)微幅調整如下：I t =I 0 e -αhD +△ε其中，△ε代表由複數剩餘光強度所得到的光強度補償標準差，代表紡織品T在光強度檢測裝置300上的涵蓋面積之直徑，α代表紡織品T的光吸收係數，I 0代表光源100發出之光線的初始光強度，I t 代表光強度檢測裝置300所檢測到之光線的剩餘光強度。 Specifically, the inventors slightly adjust the equation (3) as follows: I t = I 0 e - αhD + Δ ε where Δ ε represents the standard deviation of the light intensity obtained from the complex residual light intensity, Representing the diameter of the area covered by the textile T on the light intensity detecting device 300, α represents the light absorption coefficient of the textile T, I 0 represents the initial light intensity of the light emitted by the light source 100, and I t represents the light intensity detecting device 300 detects The residual light intensity of the light.
藉由納入光強度補償標準差△ε之式(6)所得到的已校正基重運算值W，將可更進一步地收斂於基重實際值，而降低誤差並提高基重檢測的精確度。 The corrected basis weight operation value W obtained by incorporating the equation (6) of the light intensity compensation standard deviation Δ ε can further converge to the base weight actual value, thereby reducing the error and improving the accuracy of the basis weight detection.
以表一為例，光強度補償標準差△ε係指每一顏 色之已上膠聚脂纖維之多個剩餘光強度取標準差後，再對所有標準差取標準差。具體來說，深藍色的已上膠聚脂纖維的剩餘光強度標準差為3.25，藍色的已上膠聚脂纖維之剩餘光強度標準差為3.12，淺藍色的已上膠聚脂纖維之剩餘光強度標準差為1.96，深紅色的已上膠聚脂纖維之剩餘光強度標準差為1.36，其餘顏色的已上膠聚脂纖維之剩餘光強度標準差可參閱表一所載，為了保持說明書的簡潔，在此不繼續羅列。光強度補償標準差△ε係指對上述標準差(包含3.25、3.12、1.96、1.36等等)取標準差得到的值，亦即表一中的1.5335。 Taking Table 1 as an example, the standard deviation of light intensity compensation Δ ε refers to the standard deviation of the residual light intensity of each sized rubber fiber of each color, and then the standard deviation is taken for all standard deviations. Specifically, the standard deviation of the remaining light intensity of the dark blue sized sizing polyester fiber is 3.25, and the standard deviation of the remaining light intensity of the blue sized sizing polyester fiber is 3.12. The light blue sized sizing polyester fiber The standard deviation of residual light intensity is 1.96, and the standard deviation of residual light intensity of dark red sized sizing polyester fiber is 1.36. The standard deviation of residual light intensity of sizing polyester fiber of other colors can be found in Table 1. Keep the instructions concise and don't continue to list them here. The light intensity compensation standard deviation Δ ε is the value obtained by taking the standard deviation of the above standard deviation (including 3.25, 3.12, 1.96, 1.36, etc.), that is, 1.5335 in Table 1.
在此例中，當工作人員欲對任何顏色之已上膠聚脂纖維做基重檢測時，可將光源100所發出光線的初始光強度I 0、光強度檢測裝置300所檢測到的剩餘光強度I t 與光強度補償標準差△ε(亦即，1.5335)帶入式(6)中，而得到已校正基重運算值W，由於式(6)額外考慮了光強度補償標準差△ε，故校正單元700根據式(6)所得到的已校正基重運算值W可更收斂於基重實際值，而降低誤差並提高基重檢測的精確度。 In this example, when the worker wants to perform the basis weight detection on the sized sized polyester fiber of any color, the initial light intensity I 0 of the light emitted by the light source 100 and the residual light detected by the light intensity detecting device 300 can be used. The intensity I t and the light intensity compensation standard deviation Δ ε (that is, 1.5335) are taken into the equation (6), and the corrected basis weight operation value W is obtained. Since the equation (6) additionally considers the light intensity compensation standard deviation Δ ε Therefore, the corrected basis weight operation value W obtained by the correction unit 700 according to the equation (6) can be more converged to the base weight actual value, thereby reducing the error and improving the accuracy of the basis weight detection.
此外，當從所有顏色的已上膠聚脂纖維之剩餘光強度算出光強度補償標準差△ε後，無論是要對哪一種顏色的已上膠聚脂纖維做基重檢測，均可在式(6)中帶入同樣的光強度補償標準差△ε(於表一的例子中為1.5335)，而無須針對不同顏色的已上膠聚脂纖維帶入數值不同的光強度補償標準差。更具體地說，本實施方式無須針對28種顏色 的已上膠聚脂纖維，採用28種數值不同的光強度補償標準差，相對地，本實施方式僅需採用同樣的光強度補償標準差△ε(亦即，1.5335)，即可針對任意顏色的已上膠聚脂纖維精確地算出已校正基重運算值。應瞭解到，本段僅係以表一的已上膠聚脂纖維做為範例，但上述光強度標準差運算單元600以及校正單元700所執行的校正手段亦可應用於其他類型之紡織品(如未上膠聚脂纖維、已上膠尼龍、或未上膠尼龍等等)，而精確地得到這些類型之紡織品的已校正基重運算值。於部份實施方式中，光強度標準差運算單元600與校正單元700可由電腦的軟體或硬體來實現。 In addition, when the light intensity compensation standard deviation Δ ε is calculated from the residual light intensity of the sized sizing polyester fibers of all colors, no matter which color of the sized sizing polyester fiber is to be subjected to the basis weight detection, (6) Bring the same light intensity compensation standard deviation Δ ε (1.5335 in the example of Table 1), without the need to introduce different values of light intensity compensation standard deviation for the sized sizing polyester fibers of different colors. More specifically, the present embodiment does not need to use 28 different values of light intensity compensation standard deviation for the sized sized polyester fibers of 28 colors. In contrast, in this embodiment, only the same light intensity compensation standard deviation is required. ε (ie, 1.5335), the corrected basis weight calculation value can be accurately calculated for the sized sizing polyester fiber of any color. It should be understood that this paragraph only takes the sizing polyester fiber of Table 1 as an example, but the above-mentioned light intensity standard deviation computing unit 600 and the correction means performed by the calibration unit 700 can also be applied to other types of textiles (such as Uncoated polyester fibers, sized nylon, or unsized nylon, etc., to accurately obtain corrected basis weight values for these types of textiles. In some embodiments, the light intensity standard deviation computing unit 600 and the correction unit 700 can be implemented by software or hardware of a computer.
第4圖繪示依據本發明另一實施方式之紡織品基重之檢測裝置的示意圖。如第4圖所示，本實施方式與前述實施方式之間的主要差異在於：在帶通濾鏡模組200b中，第一帶通濾光片210、第二帶通濾光片220與第三帶通濾光片230的排列順序與前述實施方式不同。具體來說，如第4圖所示，第二帶通濾光片220、第三帶通濾光片230與第一帶通濾光片210係依序沿著光源100往光強度檢測裝置300的方向排列，亦即，第三帶通濾光片230係位於第二帶通濾光片220與第一帶通濾光片210之間，其中第一帶通濾光片210之最低可通過波長實質上為1020奈米，第二帶通濾光片220之最低可通過波長實質上為1550奈米，第三帶通濾光片230之最低可通過波長實質上為1730奈米。值得一提的是，本發明之帶通濾光片的排列方式並不僅限於第2圖與第4圖所示，只要能夠讓基重運算值與基重實際值之間的誤差 低於3%以下，亦可採用其他排列方式。 4 is a schematic view of a textile base weight detecting device according to another embodiment of the present invention. As shown in FIG. 4, the main difference between the present embodiment and the foregoing embodiment is that in the band pass filter module 200b, the first band pass filter 210, the second band pass filter 220, and the first The order in which the three band pass filters 230 are arranged is different from the foregoing embodiment. Specifically, as shown in FIG. 4, the second band pass filter 220, the third band pass filter 230, and the first band pass filter 210 are sequentially along the light source 100 to the light intensity detecting device 300. The direction of the alignment, that is, the third band pass filter 230 is located between the second band pass filter 220 and the first band pass filter 210, wherein the lowest pass of the first band pass filter 210 The wavelength is substantially 1020 nm, the lowest passable wavelength of the second band pass filter 220 is substantially 1550 nm, and the lowest passable wavelength of the third band pass filter 230 is substantially 1730 nm. It is worth mentioning that the arrangement of the band pass filter of the present invention is not limited to the second figure and the fourth figure, as long as the error between the calculated value of the basis weight and the actual value of the basis weight can be made. Below 3%, other arrangements are also possible.
第5圖繪示依據本發明另一實施方式之紡織品基重之檢測裝置的示意圖。如第5圖所示，本實施方式與前述實施方式之間的主要差異在於：本實施方式之帶通濾鏡模組200c係由兩個帶通濾光片所組成，更進一步地說，帶通濾鏡模組200c包含第一帶通濾光片210c以及第二帶通濾光片220c。第一帶通濾光片210c與第二帶通濾光片220c係依序沿著光源100往光強度檢測裝置300的方向排列。第一帶通濾光片210c的可通過波長係介於1500奈米至2500奈米之間。第二帶通濾光片220c的可通過波長係介於1950奈米至2150奈米之間。藉由這樣的帶通濾光片組合，可更進一步地讓未上膠與已上膠的紡織品T的基重運算值更趨近於基重實際值，而降低基重運算值的誤差。由於本實施方式可降低未上膠與已上膠的紡織品T的基重運算值誤差，因此，這樣的帶通濾鏡模組200c可更佳地適用於量測紡織品T的上膠量。 FIG. 5 is a schematic view showing a detecting device for a textile basis weight according to another embodiment of the present invention. As shown in FIG. 5, the main difference between the present embodiment and the foregoing embodiment is that the band pass filter module 200c of the present embodiment is composed of two band pass filters, and further, the belt The pass filter module 200c includes a first band pass filter 210c and a second band pass filter 220c. The first band pass filter 210c and the second band pass filter 220c are sequentially arranged along the light source 100 in the direction of the light intensity detecting device 300. The passable wavelength of the first band pass filter 210c is between 1500 nm and 2500 nm. The passable wavelength of the second band pass filter 220c is between 1950 nm and 2150 nm. With such a band pass filter combination, the basis weight calculation value of the unsized and sized fabric T can be further brought closer to the actual value of the basis weight, and the error of the basis weight calculation value can be reduced. Since the present embodiment can reduce the error in the basis weight calculation value of the unsized and sized textile T, such a band pass filter module 200c can be more suitably used to measure the amount of sizing of the textile T.
於部份實施方式中，檢測裝置還可包含實際基重標準差運算單元800以及基重調整單元900。實際基重標準查運算單元800可根據複數基重實際值得到一基重補償標準差。舉例來說，可藉由磅量複數不同紡織品T而得到複數基重實際值。實際基重標準差運算單元800可對這些磅量到的基重實際值取標準差，而做為基重補償標準差。基重調正單元900可將基重運算值扣除上述基重補償標準差，以得到已調整基重運算值。藉由上述方式所得到的已調整基重運 算值可更精確地趨近於基重實際值，而有效降低誤差(誤差低於1%)。於部份實施方式中，實際基重標準差運算單元800與基重調整單元900可由電腦的軟體或硬體來實現。 In some embodiments, the detecting device may further include an actual basis weight standard deviation computing unit 800 and a basis weight adjusting unit 900. The actual basis weight check operation unit 800 can obtain a basis weight compensation standard deviation according to the actual value of the complex basis weight. For example, the actual value of the complex basis weight can be obtained by weighing a plurality of different textiles T. The actual basis weight standard deviation operation unit 800 can take the standard deviation of the actual values of the basis weights of these pounds as the basis weight compensation standard deviation. The basis weighting unit 900 may subtract the basis weight compensation standard deviation from the basis weight calculation value to obtain the adjusted basis weight operation value. Adjusted base transport obtained by the above method The calculated value can be more accurately approximated to the actual value of the basis weight, and the error is effectively reduced (the error is less than 1%). In some embodiments, the actual basis weight standard deviation operation unit 800 and the basis weight adjustment unit 900 can be implemented by software or hardware of a computer.
以下將以各種不同紡織品T的實驗數據佐證上述實施方式可有效降低基重運算值與基重實際值之間的誤差。 The experimental data of various textiles T will hereinafter prove that the above embodiment can effectively reduce the error between the calculated value of the basis weight and the actual value of the basis weight.
上述表七係以已上膠之尼龍(nylon)做為紡織品，並羅列了28種不同顏色之已上膠尼龍的基重運算值、基重實際值以及已調整基重運算值。由表七可知，當光源100之發光波長為2050奈米，並搭配可通過波長係介於1500奈米至2500奈米之間的第一帶通濾光片210c，以及可通過波長係介於1950奈米至2150奈米之間的第二帶通濾光片220c時，將基重運算值扣除基重補償標準差(即表七中的1.43)所得到的已調整基重運算值，可更加地趨近於基重實際值，而有效降低誤差(誤差低於1%)，而進一步地提升基重運算的精確度。 The above table 7 is a stenciled nylon (nylon) as a textile, and lists the base weight calculation value, the base weight actual value and the adjusted basis weight calculation value of 28 different colors of the sized nylon. It can be seen from Table 7 that when the light source 100 has an emission wavelength of 2050 nm and is matched with a first band pass filter 210c which can pass between 1500 nm and 2500 nm, and the wavelength range is When the second band pass filter 220c is between 1950 nm and 2150 nm, the basis weight calculation value is subtracted from the basis weight compensation standard deviation (ie 1.43 in Table 7), and the adjusted basis weight calculation value can be obtained. More close to the actual value of the basis weight, and effectively reduce the error (error less than 1%), and further improve the accuracy of the basis weight operation.
以表七中的深藍色已上膠尼龍為例，其基重實際值為90.79，而基重運算值為92.18。將基重運算值(92.18)扣除基重補償標準差(1.43)所得到的已調整基重運算值為90.75，其與基重實際值(90.79)的誤差僅有0.04，亦即0.044%，遠低於1%。因此，將基重運算值再扣除基重補償標準差所得到的已調整基重運算值，可更加地趨近於基重實際值，而進一步地提升基重運算的精確度。 Taking the dark blue sized nylon in Table 7 as an example, the actual base weight is 90.79, and the base weight is 92.18. The adjusted basis weight obtained by subtracting the basis weight compensation standard (1.43) from the basis weight calculation value (92.18) is 90.75, and the error from the actual value of the basis weight (90.79) is only 0.04, which is 0.044%. Less than 1%. Therefore, the adjusted basis weight operation value obtained by subtracting the basis weight compensation standard deviation from the basis weight operation value can be more closely approximated to the base weight actual value, and the accuracy of the basis weight operation is further improved.
於部份實施方式中，基重調整單元900可將校正單元700(可參閱第3圖及前文所述)所得到的已校正基重運算值扣除上述基重補償標準差，來得到已調整基重運算值。換句話說，校正單元700可藉由光強度補償標準差得到 已校正基重運算值，以收斂於基重實際值，接著，基重調整單元900可將此已校正基重運算值扣除基重補償標準差，而得到更進一步地收斂於基重實際值的已調整基重運算值。 In some embodiments, the basis weight adjustment unit 900 may subtract the above-mentioned basis weight compensation standard deviation from the corrected basis weight calculation value obtained by the correction unit 700 (refer to FIG. 3 and the foregoing) to obtain the adjusted basis. Recalculate the value. In other words, the correction unit 700 can be obtained by compensating for the standard deviation of the light intensity. The basis weight operation value is corrected to converge to the base weight actual value, and then the basis weight adjustment unit 900 may subtract the basis weight compensation standard deviation from the corrected basis weight operation value to obtain a further convergence to the base weight actual value. The base weight calculation value has been adjusted.
