Description
本發明是有關於一種量測裝置，特別是指一種薄金屬帶張力量測裝置。 The invention relates to a measuring device, in particular to a thin metal belt tension measuring device.
在薄鋼帶盤捲過程中，維持穩定的張力攸關鋼片的品質，當張力過大時，薄鋼帶容易斷裂，會影響製程穩定性，而張力過小時，則會有捲形不佳的問題。另外，由於薄鋼帶的生成速度較快，約每秒15至20公尺，且張力範圍較小，約小於10公斤，因此，需要使用機械摩擦較小的張力感測器，以避免張力訊號失真。然而目前市售機械摩擦較小的張力感測器是利用應變規來量測張力變化量，但受限於其機械架構之關係，導致張力較小的範圍無法量測，最小量測範圍需高於10公斤，因此難以符合薄鋼帶盤捲製程之張力量測作業所需。 In the process of coiling thin steel strip, the quality of the tension is maintained. When the tension is too large, the thin steel strip is easy to break, which will affect the stability of the process. When the tension is too small, there will be a poor roll shape. problem. In addition, since the thin steel strip is formed at a relatively fast speed of about 15 to 20 meters per second and the tension range is small, about less than 10 kilograms, it is necessary to use a tension sensor with less mechanical friction to avoid the tension signal. distortion. However, the tension sensors that are currently commercially available with less mechanical friction use strain gauges to measure the amount of tension change, but are limited by the mechanical structure, resulting in a small range of tension cannot be measured, and the minimum measurement range needs to be high. At 10 kg, it is difficult to meet the tension measurement requirements of the thin steel strip coiling process.
因此，本發明之一目的，即在提供一種可有效反應小範圍之張力感測量，且線性度佳、誤差小之薄金屬帶張力量測裝置。 Accordingly, it is an object of the present invention to provide a thin metal strip tension measuring device which is effective in reacting a small range of tension measurement and has good linearity and small error.
於是，本發明薄金屬帶張力量測裝置，包含一 基座、一立設於該基座上之I型支架、一輥輪，以及一荷重感測器。該輥輪樞設於該I型支架上，且受該薄金屬帶之位移帶動而能相對該I型支架轉動。該荷重感測器設置於該I型支架上並鄰近於該輥輪，且使該薄金屬帶施加於該輥輪上的垂直作用力也能作用於該荷重感測器上。 Thus, the thin metal strip tension measuring device of the present invention comprises a The base, an I-shaped bracket erected on the base, a roller, and a load sensor. The roller is pivotally disposed on the I-shaped bracket and is driven by the displacement of the thin metal strip to be rotatable relative to the I-shaped bracket. The load sensor is disposed on the I-shaped bracket adjacent to the roller, and a vertical force applied to the roller by the thin metal band can also act on the load sensor.
本發明之功效在於能限制該I型支架只能相對於該基座做X方向移動量及小幅度的Y軸旋轉自由度，進而可確保在該輥輪上之作用力能垂直施加於該荷重感測器上，如此，可有效反應小範圍之張力感測量，且線性度佳、誤差小。 The effect of the invention is to limit the X-axis movement amount and the small-scale Y-axis rotation degree of the I-shaped bracket relative to the base, thereby ensuring that the force on the roller can be applied perpendicularly to the load. On the sensor, in this way, the tension measurement of a small range can be effectively reflected, and the linearity is good and the error is small.

The uprights 23 are respectively connected between the bottom surface of the side plates 31 and the top surface of the bottom plate 21 for supporting the I-shaped bracket 3 above the bottom plate 21.

該輥輪4是樞設於該I型支架3之該等側板31間。而該荷重感測器5設置於固定座體25上且用以接觸該I型支架3之連接板32，並鄰近於該輥輪4。 The roller 4 is pivotally disposed between the side plates 31 of the I-shaped bracket 3. The load sensor 5 is disposed on the fixing base 25 and is adjacent to the connecting plate 32 of the I-shaped bracket 3 and adjacent to the roller 4.
參閱圖1、2，在使用上，該薄金屬帶張力量測裝置應用於量測一薄金屬帶6之張力，本實施例中的薄金屬帶6是以盤捲或解捲過程中的薄鋼帶做說明。該薄金屬帶6帶動盤捲過程中之一解捲輪7如圖中箭號91所示進行順時針旋轉，進而繞行該輥輪4，再搭配一盤捲輪8如圖中箭號91所示進行順時針旋轉而進行盤捲，藉由該解捲輪7及該盤捲輪8之設置，薄金屬帶6會產生張力F1，此時張力F1進一步對於I型支架3產生一向左之作用力，而向左位移量被該荷重感測器5限制位移，如此一來可藉由該荷重感測器5量測到薄金屬帶6之張力值。同理，在解捲過程中，該解捲輪7如圖中箭號92所示進行逆時針旋轉，該盤捲輪8靜止或如圖中箭號92所示進行逆時針旋轉但轉速 小於該解捲輪7時，該薄金屬帶6由該盤捲輪8朝向該解捲輪7位移，薄金屬帶6會產生如圖中所示之張力F2，此時張力F2對於I型支架3亦會產生一向左之作用力，藉此亦可透過該荷重感測器5量測到薄金屬帶6之張力值。 Referring to Figures 1 and 2, in use, the thin metal strip tension measuring device is applied to measure the tension of a thin metal strip 6, and the thin metal strip 6 in this embodiment is thin during coiling or unwinding. The steel strip is used for explanation. The thin metal strip 6 drives one of the unwinding wheels 7 in the coiling process to rotate clockwise as shown by the arrow 91, and then bypasses the roller 4, and then cooperates with a reel 8 as shown by the arrow 91 The coiling is performed by clockwise rotation, and by the setting of the unwinding wheel 7 and the reeling wheel 8, the thin metal strip 6 generates tension F1, and the tension F1 further produces a leftward direction for the I-shaped bracket 3. The force is applied, and the amount of displacement to the left is limited by the load sensor 5, so that the tension value of the thin metal strip 6 can be measured by the load sensor 5. Similarly, during the unwinding process, the unwinding wheel 7 rotates counterclockwise as indicated by arrow 92 in the figure, and the reeling wheel 8 is stationary or counterclockwise as shown by arrow 92 in the figure but the rotation speed When it is smaller than the unwinding wheel 7, the thin metal strip 6 is displaced by the coiling reel 8 toward the unwinding wheel 7, and the thin metal strip 6 produces a tension F2 as shown in the figure, at which time the tension F2 is for the I-shaped bracket. 3 also produces a leftward force, whereby the tension value of the thin metal strip 6 can also be measured by the load sensor 5.
更詳細地來說，張力F1或張力F2對於I型支架3產生一向左之作用力時，該等旁接板24能限制該I型支架3與該底板21做X軸的旋轉自由度及Y軸方向移動量，而立柱23則能限制該I型支架3的Z軸旋轉自由度及Z軸方向移動量，因此，該I型支架3只能相對於該底板21做X軸方向移動量及小幅度的Y軸旋轉自由度轉動。由於與該I型支架3相連接之該等立柱23及該等旁接板24的架構之機械磨擦力較小，因此，可利用該荷重感測器5量測X軸方向之微小拉力，再搭配該薄金屬帶6之輸送方向分別平行於X軸及垂直Y軸上，因此，該荷重感測器5平行於X軸方向安裝時，可避免量測到Y軸之力，因而可完全反應X軸方向之張力。如此可確保在該輥輪4上之作用力能垂直施加於該荷重感測器5上，使得該荷重感測器5可有效反應小範圍之張力感測量，且線性度佳、誤差小。 In more detail, when the tension F1 or the tension F2 generates a leftward force to the I-shaped bracket 3, the bypass plates 24 can restrict the rotation degree of the X-axis of the I-shaped bracket 3 and the bottom plate 21 and Y. The amount of movement in the axial direction, and the column 23 can limit the Z-axis rotational freedom of the I-shaped bracket 3 and the amount of movement in the Z-axis direction. Therefore, the I-shaped bracket 3 can only move in the X-axis direction with respect to the bottom plate 21 and A small amplitude of the Y-axis rotation is rotated. Since the mechanical frictional force of the structure of the uprights 23 and the side sills 24 connected to the I-shaped bracket 3 is small, the load sensor 5 can be used to measure the small tensile force in the X-axis direction, and then The conveying direction of the thin metal strip 6 is parallel to the X-axis and the vertical Y-axis, respectively. Therefore, when the load sensor 5 is mounted parallel to the X-axis direction, the force of the Y-axis can be prevented from being measured, and thus the reaction can be completely completed. Tension in the X-axis direction. This ensures that the force on the roller 4 can be applied perpendicularly to the load sensor 5, so that the load sensor 5 can effectively respond to a small range of tension measurement, and has good linearity and small error.
參閱圖3，為該薄金屬帶張力量測裝置之實際測試結果，測試重量從10至60牛頓(N)來回進行測試，如圖所示可知，壓力增加及減少測試斜率穩定且重現性高，線性度佳且誤差小，圖中最大誤差約為0.1V，對應量約2N，結果顯示此架構可有效反應小範圍之張力感測量。 Referring to Figure 3, the actual test results of the thin metal strip tension measuring device, the test weight is tested from 10 to 60 Newtons (N), as shown in the figure, the pressure increase and the test slope are stable and the reproducibility is high. The linearity is good and the error is small. The maximum error in the figure is about 0.1V, and the corresponding amount is about 2N. The result shows that this architecture can effectively reflect the small-range tension measurement.
綜上所述，本發明薄金屬帶張力量測裝置藉由 上述構造設計，能限制該I型支架3只能相對於該基座2做X方向移動量及小幅度的Y軸旋轉自由度，進而可確保在該輥輪4上之作用力能垂直施加於該荷重感測器5上，如此，可有效反應小範圍之張力感測量，且線性度佳、誤差小。故確實能達成本發明之目的。 In summary, the thin metal strip tension measuring device of the present invention is The above-mentioned structural design can limit the X-direction movement amount and the small-amplitude Y-axis rotation degree of the I-shaped bracket 3 relative to the base 2, thereby ensuring that the force on the roller 4 can be vertically applied to The load sensor 5 can effectively reflect a small range of tension measurement, and has good linearity and small error. Therefore, the object of the present invention can be achieved.
