Description

用於改變織布機托樑的動態性能的方法及裝置    Method and device for changing dynamic performance of loom support beam   

本發明係關於一種用於改變織布機托樑之動態性能的方法，以及一種具有經調適以執行此類方法之托樑的織布機。 The present invention relates to a method for changing the dynamic performance of a loom joist, and a loom with a joist that is adapted to perform such a method.

就織布機而言，在先前技術中已知用於使經線偏轉的裝置，該等裝置被稱為托樑、托輥(backrest roll)或後樑(whip roll)。 With respect to looms, devices for deflecting warp threads are known in the prior art, and these devices are called joists, backrest rolls or whip rolls.

舉例而言，DE 10 2006 061 376 A1展示此類裝置。此係關於用於織布機之托樑，其中經向上之經線運動藉由線偏轉元件補償或均勻化，該線偏轉元件可樞轉地配置於質量最佳化之板片彈簧上。 For example, DE 10 2006 061 376 A1 shows such a device. This is a joist for a loom, in which the warp movement in the warp direction is compensated or equalized by a thread deflection element that can be pivotally arranged on a plate spring with optimized mass.

在先前技術中之彼方面中，所提到的質量最佳化之目的為在較高織布速度下以產生最小可能經線拉力之方式組態或體現托樑之動態性能。此藉由線偏轉元件之較小慣性質量及板片彈簧之較小慣性質量來達成。 In the other aspect of the prior art, the purpose of the quality optimization mentioned is to configure or embody the dynamic performance of the joists at a higher weaving speed in a way that produces the smallest possible warp tension. This is achieved by the smaller inertial mass of the wire deflection element and the smaller inertial mass of the leaf spring.

WO 2012 031 802 A2描述用偏轉元件引導經線之托樑，該偏轉元件經由織布機上之彈性元件支撐或固定。此處，亦描述在線偏轉元件上提供最小可能慣性質量以便保持較小經線負載或應力之目標或目的。 WO 2012 031 802 A2 describes guiding a warp beam with a deflection element which is supported or fixed via an elastic element on the loom. Here, the goal or purpose of providing the smallest possible inertial mass on the wire deflection element in order to keep the warp load or stress small is also described.

DE 1 138 715 A揭示可旋轉地支撐於張緊桿中之托樑，該等張緊桿可圍繞機架上之固定軸樞轉，且用於在儲力器作用下將張緊樑壓在 經線上。就此而言，定位於張緊桿中之托樑軸承中之至少一者包含用於同時減少自旋及托樑樞轉運動中之振盪的制動裝置。以此方式，托樑之動態性能藉由改變槓桿比率或關係來進行調節。 DE 1 138 715 A discloses joists that are rotatably supported in tensioning rods, which can pivot around a fixed axis on the frame and are used to press the tensioning beam under the action of the accumulator Warp. In this regard, at least one of the joist bearings positioned in the tensioning rod includes a braking device for simultaneously reducing spin and oscillations in the pivot movement of the joist. In this way, the dynamic performance of the joists is adjusted by changing the leverage ratio or relationship.

在此類托樑裝置之使用中，現已發現，最小可能經線負載並非對於所有織布條件或要求以及所有編織品均合理或適用。尤其在具有較高緯密度或緯紗規格(亦即在編織品之規定長度中具有大量緯線)之工業編織品中，已顯示較大經線拉力或經線張力至少在織布過程之某一階段中係有利的。該階段為緯線在***至織機梭口後抵靠已有編織品之邊緣或交織點藉由織筘進行打緯之階段。若實現了較高緯密度(亦即編織品之規定長度中之大量緯線)，則較大經線拉力或經線張力至少在筘打緯期間更為有利，此係由於當抵靠交織點藉由織筘對新的緯線進行打緯時交織點後退更少。藉此，實現連續緯線在編織品中彼此緊密貼合。 In the use of such joist devices, it has been found that the minimum possible warp load is not reasonable or applicable to all fabric conditions or requirements and all knitted products. Especially in industrial woven products with higher weft density or weft yarn specifications (that is, a large number of weft threads in the specified length of the woven product), greater warp tension or warp tension has been shown at least at a certain stage of the weaving process The Chinese system is favorable. This stage is the stage in which the weft thread is inserted into the shed of the loom to abut the edge or interweaving point of the existing knitwear by the weaving reed. If a higher weft density (that is, a large number of wefts in the specified length of the knitted fabric) is achieved, a larger warp tension or warp tension is more advantageous at least during the reed beat-up, which is due to the When the new reed is beaten by the weaving reed, the interlacing point moves back less. In this way, the continuous weft threads are tightly attached to each other in the knitted fabric.

另一方面，如先前技術中已詳細解釋，在織布過程之其他階段中經線張力不應不必要地過大。此尤其針對在兩次筘打緯之間發生的梭口改變階段。在彼方面，取決於編織品之圖案，發生所有或若干經線自上梭口至下梭口中之轉換(且反之亦然)。在此梭口改變中，經線在幾何形狀上自其穿過織布機之直線行進或延伸偏轉。此偏轉由於織布綜片豎直地朝上或朝下推動經線而實現。藉此，經線藉由綜片中之摩擦而具有負載或應力。為了避免線斷裂，在此梭口改變期間存在最小可能經線張力為有利的。 On the other hand, as explained in detail in the prior art, the warp tension should not be unnecessarily excessive in other stages of the weaving process. This is especially aimed at the shed change phase that occurs between two reed beats. On the other hand, depending on the pattern of the knitwear, the conversion of all or several warp threads from the upper shed to the lower shed (and vice versa) takes place. In this shed change, the warp threads travel geometrically from their straight line through the loom or extend and deflect. This deflection is achieved by pushing the warp threads vertically upwards or downwards. By this, the warp has a load or stress due to friction in the heddle. To avoid thread breakage, it is advantageous to have the smallest possible warp tension during this shed change.

因此顯而易見，對於某些編織品，至少在筘打緯期間短時間地暫時產生較大經線張力將為有利的，而對於其他編織品，同樣在筘打緯期間用較小經線張力操作為合理且適用的。 It is therefore obvious that for some knitted fabrics, it will be advantageous to temporarily generate a large warp tension temporarily for at least a short period of time during reed beat-up, while for other knitted fabrics, the operation with a smaller warp tension during reed beat-up is also Reasonable and applicable.

因此目標為，對於不同編織品類型，至少在織布機之筘打緯期間能夠用適合於該編織品類型之不同經線張力操作。 The goal is therefore to be able to operate with different warp tensions suitable for the type of knitwear for different types of knitwear, at least during the reed beat-up of the loom.

該目標係藉由根據獨立申請專利範圍之方法及織布機來達成。 This goal is achieved by methods and looms based on independent patent applications.

用於改變織布機托樑之動態性能的方法係關於具有用於使經線偏轉之至少一個偏轉元件的托樑。該偏轉元件可例如由連續穿通的彎曲金屬片構成，該偏轉元件之縱軸橫向於經線之方向延伸。經線通常自經軸開始經由托樑之偏轉元件引導至織布機之梭口成形元件。 The method for changing the dynamic performance of the loom joists relates to joists having at least one deflection element for deflecting the warp threads. The deflection element can be formed, for example, by a continuous bent metal sheet, the longitudinal axis of the deflection element extending transverse to the direction of the warp. The warp threads are usually guided from the warp beam to the shed forming element of the loom via the deflection element of the joist.

當然，代替單一偏轉元件，遍及織布機寬度而分佈之若干偏轉元件亦係可能的，例如適合於織布寬度之若干金屬片元件。 Of course, instead of a single deflection element, several deflection elements distributed across the width of the loom are also possible, for example, a number of metal sheet elements suitable for the width of the loom.

偏轉元件經由一或多個彈簧元件以如下方式與織布機機架連接：在施加或強加引起偏轉元件相對於機架之加速或運動的力之後，慣性力及彈簧力對偏轉元件變得有效。在織布機操作期間，加速力藉由經線施加至偏轉元件上。慣性力主要涉及由於偏轉元件之慣性質量塊之加速而產生的力。此慣性質量塊亦可包括其他結構組件，該等組件以如下方式緊固在偏轉元件上或與偏轉元件連接：在偏轉元件之運動或偏轉期間，該等結構組件亦與偏轉元件一起移動。 The deflection element is connected to the loom frame via one or more spring elements in such a way that after applying or forcing a force that causes acceleration or movement of the deflection element relative to the frame, the inertial and spring forces become effective on the deflection element . During operation of the loom, acceleration forces are applied to the deflection element by means of warp threads. The inertial force mainly relates to the force generated by the acceleration of the inertial mass of the deflection element. The inertial mass may also include other structural components that are fastened to or connected to the deflection element in the following manner: during the movement or deflection of the deflection element, the structural components also move with the deflection element.

彈簧力藉由偏轉元件與相關彈簧元件自靜止位置偏轉至偏轉位置而產生。自靜止位置至偏轉位置之此偏轉一般已由於在張力下經由偏轉元件引導之經線而產生。舉例而言，板片彈簧用作彈簧元件，該等板片彈簧在其一個末端處支撐於織布機機架上且在其另一末端處承載偏轉元 件。然而，亦可設想其中偏轉元件可移動地支撐於機架上(例如鉸接接頭中)之配置，另外藉此彈簧元件以使得彈簧之一個末端在偏轉元件之偏轉期間偏轉之方式配置於偏轉元件與機架之間。考慮將板片彈簧、扭轉彈簧、螺旋卷簧或空氣彈簧用作彈簧。 The spring force is generated by the deflection element and related spring elements deflecting from the rest position to the deflection position. This deflection from the rest position to the deflection position has generally been caused by the warp guided by the deflection element under tension. For example, leaf springs are used as spring elements, which are supported on the loom frame at one end and carry deflection elements at the other end. However, a configuration in which the deflection element is movably supported on the frame (for example, in an articulated joint) is also conceivable, and in this way, the spring element is arranged on the deflection element and Between racks. Consider using leaf springs, torsion springs, coil springs or air springs as springs.

本發明之特徵在於，改變在偏轉元件加速期間有效之慣性質量以便使托樑之動態性能適用於不同織布條件或要求。此情形以更換、移除或補充偏轉元件之部件或與偏轉元件連接之其他組件之方式發生。 The invention is characterized by changing the effective inertial mass during acceleration of the deflection element in order to adapt the dynamic performance of the joist to different weaving conditions or requirements. This situation occurs by replacing, removing or supplementing the components of the deflection element or other components connected to the deflection element.

藉由偏轉元件之慣性質量改變，托樑之動態性能在較短急動加速過程期間(例如在筘打緯期間)比在緩慢、更類似於正弦進行之加速過程期間(例如在梭口改變期間)更強烈地受影響。 By changing the inertial mass of the deflection element, the dynamic performance of the joist is during a shorter jerk acceleration process (eg during reed beat-up) than during a slower, more sinusoidal acceleration process (eg during a shed change) ) Is more strongly affected.

此對於達成偏轉元件之較大阻力以用於在筘打緯期間達成較大經線張力而不會在梭口改變範圍內不必要地增大經線張力(換言之，在梭口改變期間經線之較大應力)尤其重要。 This is to achieve greater resistance to the deflection element for achieving greater warp tension during reed beating without unnecessarily increasing warp tension within the shed change range (in other words, warp during shed change The greater the stress) is particularly important.

在具有不那麼高的緯密度之編織品中，則相反地藉由減小有效慣性質量，經線負載或應力可在織布循環(筘打緯及梭口改變)之整個範圍內保持較小，此係由於較輕偏轉元件以更小阻力抵抗加速過程。 In woven fabrics with less high weft density, on the contrary, by reducing the effective inertial mass, the warp load or stress can be kept small throughout the entire range of the weaving cycle (reed weft and shed change) This is because the lighter deflection element resists the acceleration process with less resistance.

因此在第一方法具體實例中提出，當織布機自具有較低緯密度之編織品轉換至具有較高緯密度之編織品時，對偏轉元件有效之慣性質量藉由更換或補充部件而增加。 Therefore, in the specific example of the first method, it is proposed that when the loom is switched from a woven product with a lower weft density to a woven product with a higher weft density, the effective inertial mass for the deflection element is increased by replacing or supplementing parts .

增加之慣性質量實現偏轉元件對急動運動之更大阻力。此導致在織布機之急動筘打緯期間在經線中產生暫時較大的經線張力。在筘打緯期間之此等暫時較大的經紗張力為製造具有較高緯密度之編織品的前提 條件。 The increased inertial mass achieves greater resistance of the deflection element to jerk movements. This results in a temporarily large warp tension in the warp during the rapid reed beat-up of the loom. These temporarily larger warp tensions during the reed beat-up period are a prerequisite for the manufacture of woven products with a higher weft density.

在第二方法具體實例中提出，當織布機自具有較高緯密度之編織品轉換至具有較低緯密度之編織品時，對偏轉元件有效之慣性質量藉由更換或移除部件而減小。減小之慣性質量實現偏轉元件對急動運動之更小阻力。此導致在織布機之筘打緯期間，相較於之前現在產生較小經線張力，且因此產生經線之較小應力。 In the specific example of the second method, it is proposed that when the loom is switched from a woven product with a higher weft density to a woven product with a lower weft density, the effective inertial mass for the deflection element is reduced by replacing or removing parts small. The reduced inertial mass enables the deflection element to have less resistance to jerk movements. This results in less warp tension during the reed beat-up of the loom than before, and therefore less stress on the warp.

托樑之動態性能的不同甚至導致對偏轉元件有效之慣性質量的較小不同。然而，有利的係有效慣性質量以介於1.5與8之間的係數、較佳地2與5之間的係數(例如2.5或3或4)增加或減少。利用各種不同額外或補充質量塊以相應適當階躍之分類，動態性能可適用於最多變化之要求，例如緯密度或旋轉速度。 The difference in the dynamic performance of the joist even leads to a small difference in the effective inertial mass of the deflection element. However, the effective effective mass of inertia is increased or decreased by a factor between 1.5 and 8, preferably a factor between 2 and 5 (eg 2.5 or 3 or 4). Using various additional or supplementary masses with corresponding appropriate step classification, the dynamic performance can be applied to the most varied requirements, such as latitude density or rotation speed.

本發明之另一態樣係關於具有托樑之織布機，該托樑具有用於使經線偏轉之至少一個偏轉元件。偏轉元件經由一或多個彈簧元件以如下方式與織布機連接：在經由經線施加或強加力及運動之後，慣性力及彈簧力對偏轉元件變得有效。在織布機操作期間，此類加速力藉由經線施加至偏轉元件上。 Another aspect of the invention relates to a loom with a joist, which has at least one deflection element for deflecting the warp threads. The deflection element is connected to the loom via one or more spring elements in such a way that after the force and movement are applied or forced via the warp, the inertial force and the spring force become effective for the deflection element. During operation of the loom, such acceleration forces are applied to the deflection element by means of warp threads.

慣性力主要涉及由於偏轉元件之慣性質量塊之加速而產生的力。緊固於偏轉元件上之其他組件亦可屬於此慣性質量塊。 The inertial force mainly relates to the force generated by the acceleration of the inertial mass of the deflection element. Other components fastened to the deflection element can also belong to this inertial mass.

彈簧力由於偏轉元件與相關彈簧元件自靜止位置偏轉至偏轉位置而產生。自靜止位置至偏轉位置之此類偏轉一般已藉由在張力下經由偏轉元件引導之經線而實現。作為彈簧元件，例如可利用板片彈簧，其末端中之一者固定或支撐於織布機機架上，且其另一末端承載偏轉元件。 然而，亦可設想其中偏轉元件可移動地支撐於機架上(例如鉸接接頭中)之配置，另外藉此彈簧元件以如下方式配置於偏轉元件與機架之間：在偏轉元件偏轉時，彈簧的一個末端亦偏轉。考慮將板片彈簧、扭轉彈簧、螺旋卷簧或空氣彈簧用作彈簧。 The spring force is generated by the deflection element and the associated spring element deflecting from the rest position to the deflection position. Such deflection from the rest position to the deflection position has generally been achieved by a warp guided by the deflection element under tension. As the spring element, for example, a leaf spring can be used, one of its ends is fixed or supported on the loom frame, and the other end thereof carries a deflection element. However, an arrangement in which the deflection element is movably supported on the frame (for example, in an articulated joint) is also conceivable, and in addition, the spring element is arranged between the deflection element and the frame in the following manner: when the deflection element is deflected, One end of the is also deflected. Consider using leaf springs, torsion springs, coil springs or air springs as springs.

根據本發明，織布機之特徵在於，可改變對偏轉元件有效之慣性質量以便使托樑之動態性能適用於不同織布條件或要求。此可變性由於偏轉元件之部件或與偏轉元件連接之部件經體現為可更換、可移除或可補充而實現。 According to the invention, the loom is characterized in that the inertial mass effective for the deflection element can be changed in order to adapt the dynamic performance of the joist to different weaving conditions or requirements. This variability is achieved because the components of the deflection element or the components connected to the deflection element are embodied as replaceable, removable or supplementable.

據展示，尤其有利的係各種不同偏轉元件或補充質量塊之分類保持就緒，藉此對偏轉元件有效之慣性質量可以1.5至8之係數、較佳地2與5之間的係數(例如2.5或3或4)增大或減少。 It has been shown that it is particularly advantageous that the classification of the various deflection elements or complementary masses is kept ready, whereby the effective inertial mass for the deflection elements can be a factor of 1.5 to 8, preferably a factor between 2 and 5 (eg 2.5 or 3 or 4) Increase or decrease.

作為根據本發明之織布機的起始點或基礎，已證明其中偏轉元件體現為彎曲金屬片之具體實例為合適的。如已在先前技術中所展示，藉由此類金屬片，有可能實現可快速跟隨經線張力之變化而不導致經線張力之較大增加的極小質量偏轉元件。 As a starting point or basis for the loom according to the invention, a specific example in which the deflection element is embodied as a curved metal sheet has proved suitable. As has been demonstrated in the prior art, with such metal sheets, it is possible to realize extremely small mass deflection elements that can quickly follow changes in warp tension without causing a large increase in warp tension.

根據本發明之織布機的尤其有利具體實例經由使用至少一個額外或補充質量塊而產生，該至少一個額外或補充質量塊經由夾持或力配合連接件與偏轉元件僅以力接合或摩擦接合之方式連接。此變化形式使得簡單組裝成為可能。不需要移除螺釘，而是簡單地必須釋放夾持或力配合連接件。 A particularly advantageous embodiment of the loom according to the invention is produced by using at least one additional or complementary mass, which is only in force or friction engagement with the deflection element via clamping or force-fitting connections Way to connect. This variant makes simple assembly possible. There is no need to remove the screws, but simply the clamping or force-fitting connection must be released.

原則上，可設想各種不同形式或形狀之額外或補充質量塊，例如具有扁平材料之桿或元件，該等質量塊安裝於遍及織布機之寬度而分 佈之偏轉元件上。然而，最有利的係使用導管作為額外或補充質量塊，或亦使用導管作為偏轉元件。可提供具有不同直徑及/或不同管壁厚度之導管。導管可(以可旋轉方式或固定支撐之方式)用作偏轉元件，或可經由可釋放連接件(例如夾持或力配合連接件)與例如體現為彎曲金屬片之偏轉元件連接。若干導管亦可***至彼此中，且因此可以節省空間之方式(比如一盒構建區塊或構建集合)組合。 In principle, it is possible to envisage additional or complementary masses of various forms or shapes, such as rods or elements with flat material, which are mounted on deflection elements distributed throughout the width of the loom. However, it is most advantageous to use a catheter as an additional or complementary mass, or also use a catheter as a deflection element. It is possible to provide catheters with different diameters and / or different wall thicknesses. The catheter can be used as a deflection element (in a rotatable manner or fixedly supported), or it can be connected to a deflection element, for example, embodied as a curved metal sheet, via a releasable connection (such as a clamping or force-fit connection). Several catheters can also be inserted into each other, and thus can be combined in a space-saving manner (such as a box of building blocks or building sets).

其藉由以下展示：圖1 在緯向上觀看到的根據本發明之織布機之具體實例的截面視圖，及圖2 織布機操作期間經紗張力與偏轉元件之運動的圖式。 It is shown by the following: FIG. 1 is a cross-sectional view of a specific example of the loom according to the present invention viewed in the weft direction, and FIG. 2 is a diagram of warp tension and movement of the deflection element during operation of the loom.

圖1以截面視圖方式展示根據本發明之織布機的具體實例，其觀看方向為在緯向上朝向該機器之後部分上。自未說明之經軸開始，經線1經引導圍繞偏轉元件2，且自此處經由用於監測該等經線之裝置3供應至織布機之前部分以及用於梭口成形及筘打緯之元件。 FIG. 1 shows a specific example of a loom according to the present invention in a cross-sectional view, the viewing direction of which is toward the rear part of the machine in the weft direction. Starting from unexplained warp beams, warp threads 1 are guided around the deflection element 2 and from here they are supplied to the front part of the loom via the device 3 for monitoring these warp threads and for shed forming and reed beat-out Of components.

在本實例中，偏轉元件2體現為彎曲金屬片。當前，該偏轉元件以彎曲金屬片之形式與支撐元件4旋擰在一起，該支撐元件在其一個末端處與空氣波紋管5連接，而另一末端支撐或固定於織布機機架6中之鉸接點處。 In this example, the deflection element 2 is embodied as a curved metal sheet. Currently, the deflection element is screwed together with the supporting element 4 in the form of a bent metal sheet, which is connected to the air bellows 5 at one end thereof, and the other end is supported or fixed in the loom frame 6 At the hinge point.

此處，空氣波紋管5形成彈簧元件，偏轉元件2經由該彈簧元件以如下方式與織布機連接：在經由經線1將力施加或強加至偏轉元件2 上之後，彈簧力對偏轉元件2變得有效。 Here, the air bellows 5 forms a spring element via which the deflection element 2 is connected to the loom in such a way that after the force is applied or imposed on the deflection element 2 via the warp 1, the spring force acts on the deflection element 2 Become effective.

在彼方面，此等彈簧力之量值取決於空氣波紋管5中氣壓之量值或等級。當然，亦可單純地提供具有相應調適之彈性或彈簧硬度的機械彈簧元件而非空氣波紋管5。因此，例如，支撐元件4可體現為板片彈簧，其底端並未絞接，而是緊緊地夾持於織布機機架6中。 On the other hand, the magnitude of these spring forces depends on the magnitude or level of the air pressure in the air bellows 5. Of course, it is also possible to simply provide mechanical spring elements with correspondingly adjusted elasticity or spring hardness instead of the air bellows 5. Therefore, for example, the supporting element 4 may be embodied as a leaf spring whose bottom end is not spliced but tightly clamped in the loom frame 6.

為了在織布機操作期間監測托樑上之過程，在偏轉元件2自身上或在支撐元件4上或在彈簧5與機架6之間安裝感測器(例如電感式位移感測器)係合理或適用的。 In order to monitor the process on the joists during the operation of the loom, sensors (such as inductive displacement sensors) are installed on the deflection element 2 itself or on the support element 4 or between the spring 5 and the frame 6 Reasonable or applicable.

支撐元件4及偏轉元件2經由螺紋連接件7以使得管狀額外或補充質量塊8可夾持於偏轉元件2與支撐元件4之間的方式彼此連接。當然，補充質量塊8之其他形式或形狀亦係可能的，例如實體材料桿或者具有矩形橫截面之元件。藉由釋放夾持連接件2、4、7，可移除或用另一質量塊更換補充質量塊8。 The support element 4 and the deflection element 2 are connected to each other via a threaded connection 7 in such a way that the tubular additional or complementary mass 8 can be clamped between the deflection element 2 and the support element 4. Of course, other forms or shapes of the complementary mass 8 are also possible, such as rods of solid material or elements with a rectangular cross section. By releasing the clamping connectors 2, 4, 7, the supplementary mass 8 can be removed or replaced with another mass.

在偏轉元件2之運動期間，此補充質量塊8與其一起移動，且因此在將加速力施加或強加至偏轉元件2上期間產生或多或少的較大額外慣性力。該慣性力抵抗偏轉元件2之加速。在織布機操作期間，此類加速藉由經由經線1作用於偏轉元件2上之力產生。藉由梭口改變過程及織布機之筘打緯而在經線中產生此等力及此等力引起的偏轉元件2之運動。 During the movement of the deflection element 2, this supplementary mass 8 moves with it, and therefore generates a more or less large additional inertial force during the application or imposition of acceleration forces on the deflection element 2. This inertial force resists the acceleration of the deflection element 2. During operation of the loom, such acceleration is generated by the force acting on the deflection element 2 via the warp 1. These forces and the movement of the deflection element 2 caused by these forces are generated in the warp by the shed change process and the reed beat-up of the loom.

圖2展示在織布機操作期間量測值之各種不同時間相關進展或曲線。 Figure 2 shows various time-dependent progress or curves of measured values during operation of the loom.

實線展示在若干織布循環時間跨度內經線拉力10或經線張力10(cN每線)之進展或曲線。在彼方面，尖峰10.1、10.2分別標記筘打 緯。分別在每兩次筘打緯之間，吾人類似地識別出經線張力10之增加，然而該等增加經組態成較少急動。在此等範圍中分別發生一次梭口改變，其中經線1之一個部分自頂部改變至底部，而經線1之另一部分在相反方向上移動(圖1中之雙箭頭11)。 The solid line shows the progression or curve of warp tension 10 or warp tension 10 (cN per thread) over several woven cycle time spans. On the other hand, spikes 10.1 and 10.2 mark reed beats respectively. Between each two reed beats, we similarly recognized an increase in warp tension 10, but these increases were configured to be less jerky. A shed change occurs in each of these ranges, where one part of the warp 1 changes from the top to the bottom, and the other part of the warp 1 moves in the opposite direction (double arrow 11 in FIG. 1).

若偏轉元件2並未以類似的快速補償運動作出反應，則經線1在筘打緯期間經歷之急動加速造成經線張力10之急動式上升。為了對比，在同一圖式中以虛線說明偏轉元件2在圍繞機架6中之樞軸點樞轉期間之運動。所說明之曲線或進展12對應於偏轉元件2在經線1之線接觸表面之區域中的位移；在圖1中，此運動用雙箭頭12說明。 If the deflection element 2 does not respond with a similar rapid compensation movement, the jerk acceleration experienced by the warp 1 during the reed beat-up causes a jerk rise of the warp tension 10. For comparison, the movement of the deflecting element 2 during pivoting around the pivot point in the frame 6 is illustrated in broken lines in the same drawing. The illustrated curve or progression 12 corresponds to the displacement of the deflection element 2 in the area where the line of the warp 1 contacts the surface; in FIG. 1, this movement is illustrated by the double arrow 12.

在當前情況下，吾人可看出，偏轉元件2在梭口改變過程之範圍內大致上與經線張力10之升高或增加同步地移動。藉此，阻止經線張力10進一步增加。此情形係由於偏轉元件2由於經線張力10增加而自靜止位置開始在朝向空氣波紋管5之方向上移動大約+2mm而發生。 In the current situation, we can see that the deflection element 2 moves substantially synchronously with the increase or increase of the warp tension 10 within the scope of the shed change process. This prevents the warp tension 10 from increasing further. This situation occurs because the deflection element 2 moves from the rest position in the direction toward the air bellows 5 by approximately +2 mm due to the increase in the warp tension 10.

在張力峰值10.1、10.2之前不久，經線張力10之曲線或進展具有最小值，該等最小值係由於此時經線1不明顯朝上或朝下偏轉地穿過織布機而產生；藉此經線1形成封閉梭口。因此，在此刻，明顯較小的經線拉力10作用於偏轉元件2。此情形使得由於空氣波紋管5之彈簧力，偏轉元件2朝向與經線1之行進方向相反的後方偏轉，在彼方面，其產生大約-2mm之運動。 Shortly before the tension peaks 10.1, 10.2, the curve or progress of the warp tension 10 has minimum values, which are caused by the warp 1 passing through the loom without deflecting up or down significantly; This warp thread 1 forms a closed shed. Therefore, at this moment, a significantly lower warp tension 10 acts on the deflection element 2. This situation causes the deflection element 2 to deflect towards the rear opposite to the direction of travel of the warp 1 due to the spring force of the air bellows 5, on the other hand, it produces a movement of approximately -2 mm.

在圖2中，吾人進一步看出，在後續筘打緯中，偏轉元件2之運動定性地具有與經線張力10之曲線或進展不同的曲線或進展。由於慣性質量塊，偏轉元件2並未如此快速地開始運動，如將對於補償或均勻化 經線張力10在筘打緯期間之極快速上升所必需的。結果為圖2中所說明之經線張力之張力峰值10.2，其在多數情況下為不合需要的，但在一些具有較高緯密度之編織品中係絕對必要的以便甚至達成所要緯密度。 In FIG. 2, we further see that in the subsequent reed beat-up, the movement of the deflection element 2 qualitatively has a curve or progression different from that of the warp tension 10. Due to the inertial mass, the deflection element 2 does not start moving so quickly, as will be necessary to compensate or equalize the extremely rapid rise of the warp tension 10 during the reed beat-up. The result is the peak tension of warp tension 10.2 illustrated in FIG. 2, which is undesirable in most cases, but it is absolutely necessary in some knitted fabrics with higher weft density in order to achieve even the desired weft density.

根據本發明，抵抗偏轉元件2之快速運動的慣性力可藉由更換、移除或補充額外或補充質量塊8而增大或減小。在彼方面，除所要緯密度外，亦考慮織布機之旋轉速度，換言之，一次織布循環之時間。在較高旋轉速度(因此極短識布循環)下，自一開始，由於梭口成形及筘打緯而產生參與元件之較高加速度。對於巨大元件(因而亦對於偏轉元件2)，此等較高加速度引起相應較大的慣性力。此等較大慣性力必須經由經線1施加或強加。因此，甚至在不變的質量關係之情況下，旋轉速度之改變或變化已引起慣性力之改變或變化。然而，在較低旋轉速度及較高緯密度之情況下，經由在偏轉元件2上裝配或安裝額外質量塊來增大慣性力可變得必要。 According to the invention, the inertial force against the rapid movement of the deflection element 2 can be increased or decreased by replacing, removing or supplementing the additional or supplemental mass 8. On the other hand, in addition to the required weft density, the rotational speed of the loom is also considered, in other words, the time for one weaving cycle. At higher rotational speeds (hence very short cloth recognition cycles), from the beginning, due to the shed formation and reed beat-up, higher accelerations of the participating elements are generated. For large elements (and therefore for deflection element 2), these higher accelerations cause correspondingly greater inertial forces. These large inertial forces must be applied or imposed via the warp 1. Therefore, even in the case of a constant mass relationship, a change or change in rotational speed has caused a change or change in inertial force. However, at lower rotational speeds and higher latitude densities, it may become necessary to increase the inertial force by fitting or installing additional masses on the deflection element 2.

在實際實踐中，例如，在編織品之緯密度為每厘米24根緯紗或投梭之情況下，在織布機之旋轉速度為每分鐘600次緯紗投梭之情況下，大約每米編織品寬度10kg量值之額外質量塊已取得良好成果。 In actual practice, for example, in the case where the weft density of the woven product is 24 wefts per centimeter or picking, and the rotation speed of the loom is 600 picks per minute, the woven product per meter The extra mass with a width of 10kg has achieved good results.

使用以此方式裝備之機器，若隨後將製造並不需要較高經線張力峰值10.1、10.2之編織品，則根據本發明，可移除或用具有較小質量之此類質量塊更換額外質量塊8。 Using a machine equipped in this way, if a knitted fabric with a higher warp tension peak of 10.1, 10.2 is not to be subsequently manufactured, according to the invention, additional mass can be removed or replaced with such masses of lower mass Block 8.

據展示，若可以係數2至5實現額外或補充質量塊8之逐步質量增大或減小，則該等額外或補充質量塊之分類足以用於大多數情況。在少數特殊情況下，質量塊之更小或甚至更大階躍亦可變得必要，因此例 如質量塊以係數1.5或甚至5與8之間的係數進行之階躍。以此，廣泛範圍內之應用相關調適係可能的。 It has been shown that if coefficients 2 to 5 can be used to achieve a gradual increase or decrease in mass of the additional or complementary mass 8, the classification of these additional or complementary masses is sufficient for most situations. In a few special cases, a smaller or even larger step of the mass can also become necessary, so for example, the mass is stepped with a coefficient of 1.5 or even between 5 and 8. In this way, application-related adaptation in a wide range is possible.
