Description

用於最佳化紗線饋送到高度不連續或以交替動作操作的紡織機器之方法及改良的紗線饋送器系統以及裝置 Method for optimizing yarn feeding to a textile machine that is highly discontinuous or operating in an alternating action and improved yarn feeder system and apparatus

本發明之標的係一種將紗線饋送到一機器並由該機器依據主要申請專利範圍前言部分之條款處理該紗線的方法。一種依據對應於獨立項申請專利範圍特徵的前言部分之條款的系統及補償器裝置亦為本發明之標的。 The subject matter of the present invention is a method of feeding a yarn to a machine and processing the yarn by the machine in accordance with the provisions of the preamble of the main patent application. A system and compensator device in accordance with the provisions of the preamble corresponding to the features of the independent patent application scope is also the subject of the present invention.

長久以來已知固定張力紗線饋送器用於將紗線或金屬線饋送到紡織機器，以製作最終製品(譬如，一編織品或一短襪)或可能地結合其他紗線來處理該紗線(譬如，製備紗線以作後續使用的機器)。 Fixed tension yarn feeders have long been known for feeding yarns or wires to a textile machine to make a final product (such as a woven or a sock) or possibly other yarns to process the yarn ( For example, machines for making yarns for subsequent use).

特別地，已知能夠以一固定的張力來饋送紗線(包含金屬線)或(紡織/技術)紗線的已知型式饋送紗線裝置。此等裝置係依據一已知的閉迴路控制原理操作，且透過一已知的固定張力紗線饋送器來實施此閉迴路控制原理。該控制方法確保以固定的張力規律地饋送紗線或金屬線，而不論該紗線之饋送速率，且亦不論紗線引入該固定張力紗線饋送器處之該紗線張力改變；以上這些皆無論張力改變係起因於逐漸用盡紗線軸、或者此類改變係起因於撕扯或源自該等紗線不規則纏繞所致之額外張力。 In particular, known types of feed yarn devices capable of feeding yarns (including metal wires) or (textile/technical) yarns at a fixed tension are known. These devices operate in accordance with a known closed loop control principle and are implemented by a known fixed tension yarn feeder. The control method ensures that the yarn or wire is fed regularly at a fixed tension regardless of the feed rate of the yarn, and regardless of the yarn tension at which the yarn is introduced into the fixed tension yarn feeder; Whether the change in tension is due to the gradual exhaustion of the yarn shaft, or such changes are due to tearing or additional tension from the irregular winding of the yarns.

一種上述型式之已知固定張力紗線饋送器係譬如以本申請人名義申請之歐洲專利案第EP1492911號的標的；此先前文件描述一種饋送器，其包括一張力感測器、一作用於饋送輪或帶輪上之致動器或馬達、及一能夠藉比較該感測器所量測之紗線張力與一期望工作張力(或設定點)來估算該紗線張力的控制單元(或電子裝置)。基於此比較，該控制單元作用於該馬達，以藉煞停或饋送紗線作用於與該馬達連接之該帶輪上，藉此修正或保持饋送到紡織機器之紗線的固定張力(以生產一製品或處理該紗線本身)。 A known fixed-tension yarn feeder of the above type is, for example, the subject of European Patent No. EP 1492911, filed in the name of the Applicant; this prior file describes a feeder which includes a force sensor, one for the feed An actuator or motor on a wheel or pulley, and a control unit (or electronic) capable of estimating the tension of the yarn by comparing the yarn tension measured by the sensor with a desired working tension (or set point) Device). Based on this comparison, the control unit acts on the motor to act on the pulley connected to the motor by means of a stop or feed yarn, thereby correcting or maintaining the fixed tension of the yarn fed to the textile machine (to produce An article or the yarn itself).

亦已知欲不連續饋送紗線；或欲依據一紗線以互不相同之至少一第一及至少一第二狀態的方式移動，由紡織機器饋送或捲取饋送紗線，到紡織機器之裝置及系統(以及實施該等裝置及系統之方法)。此類不同的饋送狀態隨著時間彼此接續。 It is also known to discontinuously feed the yarn; or to move the yarn in a manner different from at least one of the first and at least a second state, to feed or take up the feed yarn from the textile machine to the textile machine Devices and systems (and methods of implementing such devices and systems). Such different feed states continue with each other over time.

舉例來說，已知一固定張力紗線饋送器，其包括手段，譬如測力器，能夠即時量測受控紗線張力；一帶輪，紗線纏繞一圈或更多圈於其上；一電動馬達，驅動該帶輪旋轉；及控制電子裝置，根據被量測紗線之張力來調節該馬達之轉速及推因而生的該帶輪之轉速；以保持所量測之張力與一既定且可程式化值相符，可能隨紡織機器操作階段而變動。該馬達之旋轉通常在二方向作控制：其一係輸送紗線到該機器，其二係在停止或反轉階段期間從該機器回收紗線以防止紗線變鬆弛且保持紗線恆處於期望張力。 For example, a fixed tension yarn feeder is known which includes means, such as a force measuring device, capable of instantly measuring the controlled yarn tension; a pulley, the yarn being wound one or more times thereon; An electric motor that drives the pulley to rotate; and a control electronic device that adjusts the rotation speed of the motor according to the tension of the measured yarn and the rotation speed of the pulley; thereby maintaining the measured tension and a predetermined The programmable values match and may vary with the textile machine operating phase. The rotation of the motor is usually controlled in two directions: it delivers the yarn to the machine in one line, and the second is to recover the yarn from the machine during the stop or reverse phase to prevent the yarn from becoming slack and keep the yarn constant. tension.

就此型饋送器而言，紗線直接由該裝置從一線軸拾取，且纏繞於該帶輪上。明顯地，為確保受控張力的固定良好品質，在該紗線及該帶輪之間必須無滑移；僅在這種情況下，該控制電子裝置可實際上精確地計算與該帶輪相關聯之該馬達的設定速度，以保持該張力在期望數值。 In the case of this type of feeder, the yarn is picked up directly from the spool by the device and wound onto the pulley. Obviously, in order to ensure a fixed good quality of the controlled tension, there must be no slip between the yarn and the pulley; only in this case, the control electronics can actually calculate the pulley accurately The set speed of the motor is coupled to maintain the tension at a desired value.

在機器捲取速率呈固定、或機器捲取速率無較大的不連續的情況之應用，此型饋送器裝置能夠在饋送狀態改變(饋送器引入處之可變紗線張力、饋送速率改變等)時，保持固定的量測張力。明顯地，由於無滑移，因此在此等作狀態下，該饋送器能夠保持量測之張力完全地與設定值相符，且同時準確地量測饋送紗線之品質，該饋送紗線品質係確保最終製品之品質的另一基本參數。 In the case where the machine take-up rate is fixed, or the machine take-up rate is not large, the feed device can be changed in the feed state (variable yarn tension at the feeder introduction, feed rate change, etc.) Maintain a fixed measurement tension. Obviously, since there is no slip, in this state, the feeder can keep the measured tension completely in accordance with the set value, and at the same time accurately measure the quality of the fed yarn, which is the quality of the fed yarn. Another basic parameter that ensures the quality of the final product.

然而，上述型式之已知解決方案在紡織機器捲取之速率突然改變時確實地有操作上的限制。在這種型態之應用中，譬如在編織機器中選擇針後，紡織機器捲取紗線之速率變化非常快速；在這種情況下，倘旋轉該帶輪之馬達未具有必要之輸出動態來跟隨這些捲取中之改變，則當捲取增加時，將在紗線中發生張力峰值，且當捲取下降時，發生鬆弛。 However, known solutions of the above type do have operational limitations when the rate of spinning of the textile machine suddenly changes. In this type of application, such as the selection of a needle in a weaving machine, the speed at which the spinning machine takes up the yarn changes very rapidly; in this case, if the motor that rotates the pulley does not have the necessary output dynamics Following the changes in these take-ups, as the take-up increases, a tension peak will occur in the yarn, and as the take-up decreases, slack occurs.

張力控制中之此二項瑕疵(峰值及鬆弛)可能造成生產衣服中之品質問題(因製程期間不正確張力而出現織疵)，或導致紗線斷裂(起因於張力峰值)、或導致紗線從紡織機器之操作手段(譬如針)落下(起因於鬆弛)。 These two defects (peak and slack) in tension control may cause quality problems in the production of clothes (weaving due to incorrect tension during the process), or yarn breakage (caused by peak tension), or yarn Falling from the operating means of the textile machine (such as a needle) (caused by slack).

明顯地，問題愈大，有助於補償馬達響應中缺乏之動態的紗線彈性則愈小。 Obviously, the greater the problem, the smaller the yarn elasticity that helps compensate for the lack of dynamics in the motor response.

已知此型態問題之各種解決方案：例如，由以本申請人名義申請之歐洲專利案第EP2262940號已知一饋送器系統，其包含一補償器裝置，該補償器裝置連接於饋送(呈上述型式)上游，且藉由與紗線共同作用而有助於克服上述限制。在紗線已纏繞於饋送器之帶輪上後，該系統需要紗線依路線送到該補償器裝置之一可動臂且接著重新導向到饋送器之測力器。如此，該補償器裝置位於一控制迴路內(關於饋送帶輪之速度來量測張力)，以確保在該可動臂之位置變化時仍保持固定的紗線張力。 Various solutions to this type of problem are known: for example, a feeder system is known from the European Patent Application No. EP 2 262 940, which is incorporated by reference in its entirety, which incorporates a compensator device which is connected to a feed. The above type) is upstream and helps to overcome the above limitations by acting in conjunction with the yarn. After the yarn has been wound onto the pulley of the feeder, the system requires the yarn to be routed to one of the compensator devices and then redirected to the loader of the feeder. As such, the compensator device is located within a control loop (measuring the tension with respect to the speed of the feed pulley) to ensure that a constant yarn tension is maintained as the position of the movable arm changes.

換言之，依據上述先前文件，該可動臂作用如位於該帶輪(紗線積蓄於其上)與張力偵測手段(測力器)之間的一補償器裝置，且能夠補償當紗線通過藉紡織機器捲取之每一狀態時，紗線饋送或捲取所處狀態中的改變。這甚至在紗線饋送到紡織機器所處狀態中的任何改變期間，保持紗線於一固定張力的既定值。 In other words, according to the above previous document, the movable arm acts as a compensator device between the pulley (the yarn is accumulated thereon) and the tension detecting means (the force measuring device), and can compensate when the yarn passes A change in the state in which the yarn is fed or taken up in each state of the spinning machine. This maintains the yarn at a predetermined value of a fixed tension even during any change in the state in which the yarn is fed to the textile machine.

已知解決方案之可動臂係以一彈簧(譬如一蝸旋彈簧)構成，該彈簧之終端部件包括一眼孔(譬如以陶瓷製成)以供紗線通行，使該臂能執行其補償功能。 The movable arm of the known solution is constructed of a spring (e.g., a spiral spring) whose end member includes an eyelet (e.g., made of ceramic) for the passage of the yarn to enable the arm to perform its compensating function.

當使用該補償器裝置時，操作員調整彈簧力(手動或電子式)，使得供紗線延展通過之該補償器裝置終端部在工作階段期間平均在一角工作扇區之中心。如此，倘紡織機器捲取發生改變，則可產生以下情形中之一者：-在一急遽捲取增加期間，帶輪馬達因其有限動態而無法跟隨(補償)，該補償臂將落下，容許馬達有時間加速，且減少離開饋送器之張力峰值；或-在一急遽捲取減少期間，馬達因其有限動態而無法跟隨，該補償臂將升起，容許馬達有時間減速，且減少離開饋送器之張力鬆弛。 When the compensator device is used, the operator adjusts the spring force (manual or electronic) such that the end portion of the compensator device through which the yarn is extended passes is centered at an angular working sector during the working phase. Thus, if the spinning of the spinning machine changes, one of the following can occur: - during an increase in the coiling, the pulley motor cannot follow (compensate) due to its limited dynamics, the compensating arm will fall, allowing The motor has time to accelerate and reduces the tension peak leaving the feeder; or - during a rush coil reduction, the motor cannot follow because of its limited dynamics, the compensating arm will rise, allowing the motor to decelerate over time, and reducing the departure feed The tension of the device is relaxed.

明顯地，補償張力峰值及紗線鬆弛之能力係與該系統之動態(彈簧力)及該臂在角扇區內所能移動的角扇區幅度密切相關。 Clearly, the ability to compensate for peak tension and yarn slack is closely related to the dynamics of the system (spring force) and the angular extent of the arm that can be moved within the angular sector.

亦應注意到，前述先前文件藉饋送器之控制電子裝置，提供量測被使用之補償臂的位置以增加或減少帶輪速度的可能性，以及透過一電子致動器來調整該彈簧之力以使該彈簧自動地工作而無需操作員手動調整該力的可能性。 It should also be noted that the aforementioned prior document borrows the control electronics of the feeder to provide the possibility to measure the position of the compensating arm used to increase or decrease the speed of the pulley, and to adjust the force of the spring through an electronic actuator. In order for the spring to work automatically without the need for the operator to manually adjust the force.

儘管在極佳地操作下，此已知解決方案仍有限制，以下將作說明。 Although this known solution is still limited under excellent operation, it will be explained below.

該已知系統之補償器裝置實際上操作如一天平，且該彈簧之力係手動或自動地調整，以確保該彈簧之力能夠補償被饋送紗線之張力，以保持該彈簧之終端部位於移動之角扇區的中心處。該彈簧愈輕(就重量而言)，將愈正確地計算該彈簧之力，且該彈簧將愈增加該系統之響應性。然而，顯然該彈簧之力亦與該裝置可在其內有效地工作的工作張力限值相關聯。 The compensator device of the known system is actually operated such as one day, and the force of the spring is manually or automatically adjusted to ensure that the force of the spring compensates for the tension of the fed yarn to keep the end of the spring in motion At the center of the corner sector. The lighter the spring (in terms of weight), the more correctly the force of the spring will be calculated and the more the spring will increase the responsiveness of the system. However, it is apparent that the force of the spring is also associated with a working tension limit in which the device can operate effectively.

例如，針對一特定應用(譬如10公克)，校準該彈簧而適合於中-高張力，則該彈簧之力必須對應地計算；反之，當工作張力較低時，選定之力將構成該裝置之一操作限值。 For example, for a particular application (eg, 10 grams), calibrating the spring to accommodate medium-high tension, the force of the spring must be calculated accordingly; conversely, when the working tension is low, the selected force will constitute the device. An operational limit.

因此，已知的補償器裝置具有重大限制，使該彈簧必須依據期望之工作張力來定出規格尺寸，而導致該系統無彈性，或該彈簧必須由操作員定出不同的規格尺寸，或整個補償器裝置必須隨該工作張力變化而定出不同的規格尺寸。這些情況當然並非始終有可能。 Thus, known compensator devices have significant limitations in that the spring must be dimensioned according to the desired working tension, resulting in the system being inelastic, or the spring must be sized by the operator, or the entire The compensator device must be sized differently depending on the operating tension. Of course, these situations are not always possible.

除此以外，由於該補償臂之終端部係該彈簧之一部份，因此其亦因紗線之力而經歷彎曲，且這將使其位置的讀值不準確，及因此難以用作為一預測訊號用來預期藉該裝置任何補償作用以變更紗線捲取所處狀態；亦因該彈簧係可撓的而難以保持該彈簧於一特定位置。 In addition, since the end portion of the compensating arm is part of the spring, it also undergoes bending due to the force of the yarn, and this will make the reading of its position inaccurate, and thus it is difficult to use as a prediction. The signal is used to anticipate any compensation by the device to change the state in which the yarn is being taken; and because the spring is flexible, it is difficult to maintain the spring in a particular position.

最後，特別地在鬆弛階段期間之補償能力係與該臂之長度及該角扇區之幅度密切相關；因此此能力係受限的。 Finally, the compensation capability, particularly during the relaxation phase, is closely related to the length of the arm and the extent of the angular sector; thus this capability is limited.

美國專利案第US4752044號關於一種具有電子張力控制之紗線饋送器設備。該設備包括一外殼，該外殼之一側上設有旋轉手段，導向一紡織機器之紗線係纏繞於該旋轉手段上，該紗線已先與煞車手段共同作用，該煞車手段係與該外殼相關聯。在該旋轉手段之輸出處，紗線通過一固定眼孔，且接著通過位在一可動導引臂之末端處的一眼孔，該可動導引臂形成該已知紗線饋送器設備的整合一體部份；在從該導引臂之眼孔輸出處，紗線在離開該設備之前，與另一固定眼孔共同作用。 U.S. Patent No. 4,752,044 is directed to a yarn feeder apparatus having electronic tension control. The device comprises a casing, one side of which is provided with a rotating means, and the yarn guiding the textile machine is wound on the rotating means, the yarn has first cooperated with the braking means, and the braking means is connected to the casing Associated. At the output of the rotating means, the yarn passes through a fixed eyelet and then through an eyelet located at the end of a movable guiding arm which forms an integrated body of the known yarn feeder device Part; at the output from the eyelet of the guiding arm, the yarn interacts with another fixed eyelet before leaving the device.

該紗線導引臂欲在該旋轉手段之出口側上形成一紗線F儲備，及因此當紗線饋送因該紡織機器之紗線捲取的改變而減慢時在在該旋轉手段之下游。 The yarn guiding arm is intended to form a yarn F reserve on the outlet side of the rotating means, and thus downstream of the rotating means when the yarn feed is slowed by a change in the yarn take-up of the textile machine .

該紗線導引臂可直接附接至一收納於該設備之該外殼中的永磁直流電動馬達，或該紗線導引臂可與一桿件共同作用，該桿件又為與該設備整合成一體的部份且藉該外殼內之一電動馬達移動。在二個具體實施例中，一光電訊號傳感器偵測該導引臂之角位置，且發出一代表被饋送紗線之張力、及同時代表該臂之角位置且因此代表在該旋轉手段下游生成之紗線儲備的大小尺寸之訊號。 The yarn guiding arm can be directly attached to a permanent magnet DC electric motor housed in the outer casing of the device, or the yarn guiding arm can cooperate with a rod member, which is in turn The integral part is integrated and moved by an electric motor in the housing. In two embodiments, an optoelectronic signal sensor detects the angular position of the guiding arm and emits a tension representative of the fed yarn, and simultaneously represents the angular position of the arm and thus represents downstream of the rotating means. The size and size of the yarn reserve.

該(直流)電動馬達形成一電磁控制傳感器，其施加一預先仔細決定且可調整的控制力於該導引臂上。該力與紗線施加於該導引臂之眼孔上的張力相等。 The (direct current) electric motor forms an electromagnetic control sensor that applies a pre-determined and adjustable control force to the guide arm. This force is equal to the tension applied by the yarn to the eyelet of the guiding arm.

該力可藉一電路中之一電位計調整，該電路包括一提供該直流馬達電源之電源供應單元。在該電路中，界定一補償訊號，加於控制輸入至該電源供應器，該訊號被設定(且因此呈固定值)以對應一特定紗線張力。 The force can be adjusted by a potentiometer in a circuit that includes a power supply unit that provides power to the DC motor. In the circuit, a compensation signal is defined for addition to the control input to the power supply, the signal being set (and thus at a fixed value) to correspond to a particular yarn tension.

如此，該電源供應單元控制該直流馬達，以界定出該導引臂的一平衡位置，在承受紗線張力時能夠保持住。 As such, the power supply unit controls the DC motor to define an equilibrium position of the guide arm that can be held while receiving the yarn tension.

更明確地，在正常操作狀態下，該導引臂佔據二阻銷之間的特定平衡角位置，該臂可在該二阻銷之間作角移動。通過附接於該臂之眼孔的紗線所施加之力係藉作用於該桿件上、或該臂本身上之直流馬達的力而平衡。 More specifically, in the normal operating state, the guiding arm occupies a specific balance angular position between the two resistive pins, and the arm is angularly movable between the two resisting pins. The force exerted by the yarn attached to the eyelet of the arm is balanced by the force of the DC motor acting on the member or on the arm itself.

在紗線饋送狀態改變的情況下，譬如紡織機器減少使用紗線時，該導引臂關於初始平衡位置作角移動，以透過上述傳感器生成一與該位置改變對應的電訊號。該訊號傳遞到控制該設備的手段。該手段作用於控制該旋轉手段之一致動器的饋送上，以作用於紗線饋送速率，直到該導引臂返回既定平衡位置為止。在該既定平衡位置中，紗線張力係由連接至該桿件之電動馬達所生成而藉作用於該臂上之該桿件施加的控制力來補償，或紗線張力係藉由與該可動臂共同作用之該馬達直接生成於該可動臂上的力而達平衡。 In the case where the yarn feed state is changed, such as when the textile machine reduces the use of the yarn, the guide arm is angularly moved about the initial equilibrium position to generate an electrical signal corresponding to the change in position through the sensor. This signal is passed to the means of controlling the device. The means acts on the feed of the actuator controlling the means of rotation to act on the yarn feed rate until the guide arm returns to a predetermined equilibrium position. In the predetermined equilibrium position, the yarn tension is compensated by a control force generated by the electric motor connected to the rod by the rod acting on the arm, or the yarn tension is caused by the movement The motor that the arm cooperates directly generates a force on the movable arm to balance.

是以，透過該導引臂之移動，已知解決方案能夠偵測紗線饋送狀態之改變，該改變藉由對該旋轉饋送器裝置之對應作用而補償。在該解決方案中，該導引臂係直接或間接地承受一電動馬達之作用，該電動馬達之功能僅在平衡紗線之張力的改變，以保持該導引臂於休止位置。然而，該導引臂、以及與該導引臂直接或間接地共同作用的致動器，因為僅為對該旋轉手段之致動器的作用，使該臂停留於平衡位置、或在該臂已於固定銷(附接至該設備的外殼)之間作角移動後返回平衡位置，因此具有完全被動的功能。此類導引臂始終承受一既定力，且由於其在此等固定銷之間的受限移動而僅能補償紗線張力中的有限改變。 Therefore, by the movement of the guiding arm, the known solution is capable of detecting a change in the yarn feeding state, the change being compensated by the corresponding action of the rotary feeder device. In this solution, the guiding arm is directly or indirectly subjected to the action of an electric motor which functions only to balance the change in tension of the yarn to maintain the guiding arm in the rest position. However, the guiding arm, and the actuator that interacts directly or indirectly with the guiding arm, because only the action of the actuator of the rotating means, causes the arm to stay in the equilibrium position, or in the arm It has been angularly moved between the fixed pin (attached to the housing of the device) and returned to the equilibrium position, thus having a completely passive function. Such guide arms are always subjected to a given force and can only compensate for limited changes in yarn tension due to their limited movement between such fixed pins.

國際專利申請案第WO2005/111287號描述一種紗線饋送器裝置，其包括一能夠讀取被饋送到紡織機器之紗線的張力之感測器，及接受電動馬達之控制的旋轉饋送手段。該手段之移動係藉一微處理器單元控制，該微處理器單元依據該張力感測器所偵測到之紗線張力來調節該手段之速度。該感測器位於一剛性臂之自由端，該剛性臂可當紗線在從該旋轉手段輸出處改變張力且越過一與該可動臂之自由端相關聯的惰轉子或帶輪時，抵於一阻擋元件而移動。可藉由一彈簧、或一沿著與該饋送器裝置相關聯之軌道移動的台車，來達成對抗該臂之移動。 International Patent Application No. WO 2005/111287 describes a yarn feeder device comprising a sensor capable of reading the tension of a yarn fed to a textile machine, and a rotary feed means for controlling the electric motor. The movement of the means is controlled by a microprocessor unit that adjusts the speed of the means based on the yarn tension detected by the tension sensor. The sensor is located at a free end of a rigid arm that is responsive to the yarn as it changes tension from the output of the rotating means and over an idle rotor or pulley associated with the free end of the movable arm Moves as a blocking element. Movement against the arm can be achieved by a spring, or a trolley moving along the track associated with the feeder device.

該旋轉手段及該可動剛性臂係該已知饋送器裝置之整體的一部分。 The rotating means and the movable rigid arm are part of the entirety of the known feeder device.

在工作狀態下，紗線在通過該剛性臂末端處之帶輪前，至少纏繞於該旋轉手段上一次。紗線之移動造成該臂在遵循紗線饋送方向之方向旋轉，且此旋轉係受該等對抗元件(彈簧或台車)，由操作員調節之一作用抵抗。該張力感測器偵測紗線張力、將該紗線張力與一固定數值比較、且接著調整該旋轉手段之速度，以保持紗線張力接近需求之數值。該剛性臂之移動係藉後退移動來防止紗線張力任何過度快速的增加，因此防止紗線斷裂。 In the operating state, the yarn is wound at least once on the rotating means before passing the pulley at the end of the rigid arm. Movement of the yarn causes the arm to rotate in a direction that follows the direction in which the yarn is fed, and this rotation is resisted by one of the opposing elements (springs or trolleys) that is adjusted by the operator. The tension sensor detects the yarn tension, compares the yarn tension to a fixed value, and then adjusts the speed of the rotating means to maintain the yarn tension close to the desired value. The movement of the rigid arm is by recoil movement to prevent any excessively rapid increase in yarn tension, thus preventing yarn breakage.

又，該剛性臂之移動受限於一既定角扇區內。 Moreover, the movement of the rigid arm is limited to a predetermined angular sector.

在以上說明之二個先前文件的二已知解決方案中，美國專利案第US4752044號中之設備或國際專利申請案第WO2005/111287號中之裝置皆為併入補償裝置中之元件，而非可分離或能夠獨立構成者。結果為實現已知解決方案時的高複雜度，及執行任何保養工作時非常困難，以及高成本。 In the two known solutions of the two prior documents described above, the devices in the U.S. Patent No. 4,752,044 or the device in the International Patent Application No. WO 2005/111287 are all incorporated in the compensating device, rather than It can be separated or can be constructed independently. The result is high complexity in implementing known solutions, and it is very difficult and costly to perform any maintenance work.

以本申請人名義申請之國際專利申請案第WO2013/064879號描述一種依據與該文件獨立項申請專利範圍特徵的前言部分對應的方法及系統。 International Patent Application No. WO 2013/064879, filed in the name of the present application, describes a method and a system in accordance with the preamble of the features of the patent application scope of the independent application of the document.

該先前文件描述一金屬饋送器裝置，其包括一具有金屬線煞停手段之本體；一個或更多個帶輪；受各自馬達控制而供金屬線纏繞於上；一金屬線，在到達操作機器前通過補償器手段及張力感測器。控制電子裝置能夠連續地量測金屬線張力，以藉作用於該等馬達上之一第一控制迴路及作用於該補償器手段上之一第二控制迴路進行作用，而使該金屬線張力與一既定值相配。 The prior document describes a metal feeder device comprising a body having a wire stop means; one or more pulleys; a wire wound thereon by a respective motor; and a wire that reaches the operating machine Pre-compensator means and tension sensor. The control electronics can continuously measure the tension of the wire to act on one of the first control loops of the motors and the second control loop acting on the compensator means to cause the tension of the wire A set value matches.

該補償器手段亦包括一補償臂，該補償臂具有一自由端，該自由端與金屬線共同作用且接著又繞一銷作自由旋轉，該銷固定於與本體相關聯之托架上。因此該臂可藉接近或移離張力感測器(藉測力器界定)而在一既定角扇區之本體內移動。 The compensator means also includes a compensating arm having a free end that cooperates with the wire and then freely rotates about a pin that is secured to the bracket associated with the body. Thus the arm can be moved within a body of a predetermined angular sector by approaching or moving away from the tension sensor (defined by the force gauge).

該補償臂係與一彈簧相關聯，該彈簧在一側上連接至一固定於該裝置本體之支持件，且在另一側上藉一可動台車而連接至該補償臂，該可動台車係藉一電動步進馬達透過一阿基米德式或無限螺旋而移動。 The compensating arm is associated with a spring that is coupled to a support member that is fixed to the body of the device on one side and to the compensating arm by a movable trolley on the other side. An electric stepper motor moves through an Archimedes or infinite spiral.

是以，該補償臂並非直接連接至電動馬達，而該電動馬達係透過置於其間的其他組件，各具有本身慣量，來驅動且移動該補償臂。 Therefore, the compensating arm is not directly connected to the electric motor, and the electric motor drives and moves the compensating arm through the other components interposed therebetween, each having its own inertia.

該補償臂係與連接至控制單元之一位置感測器相關聯，因此該位置感測器能夠量測該臂在一既定角扇區內之位置。 The compensating arm is associated with a position sensor coupled to the control unit such that the position sensor is capable of measuring the position of the arm within a predetermined angular sector.

因此該補償臂能夠以一非靜態而係一動態方式來對抗金屬線之滑移：控制單元可實際改變該彈簧附接所至之台車(作用於電動馬達上)的位置，使該台車施加於該臂上上之力發生的改變，及將該臂帶至該既定角扇區內的期望位置。如此，該補償臂保持金屬線恆在測力計或張力感測器上正確地拉張，特別在金屬線未饋送到紡織機器之階段期間尤然。 Therefore, the compensating arm can resist the slip of the metal wire in a non-static and dynamic manner: the control unit can actually change the position of the trolley to which the spring is attached (acting on the electric motor), so that the trolley is applied to the trolley A change in the force on the arm and the bringing of the arm to a desired position within the predetermined angular sector. In this way, the compensating arm keeps the wire constantly stretched on the dynamometer or the tension sensor, especially during the phase when the wire is not fed to the textile machine.

該補償臂亦建立一金屬線儲備，該機器可在無法預料的速度改變期間從該儲備抽取。 The compensating arm also establishes a wire reserve that can be withdrawn from the reserve during unpredictable speed changes.

討論中的先前文件接著描述一饋送器裝置，其配備整合成一體且不可分離組件的補償臂，該補償臂係在一既定角扇區內自由移動。 The previous document in question then describes a feeder device that is equipped with a compensating arm that is integrated into an integral and inseparable component that is free to move within a predetermined angular sector.

該裝置之控制系統知道該臂之位置，且能夠依據量測張力或讀出位置而界定出透過一電動馬達、及一(一個或更多個)彈簧之系統所施加的力，因此閉合二個可能的控制迴路、即一關於張力的第二迴路(第一迴路係關於與帶輪連接之馬達的迴路)及一用於該臂之位置的可能第二迴路。 The control system of the device knows the position of the arm and is capable of defining a force applied by an electric motor and a system of spring(s) depending on the measured tension or readout position, thus closing the two A possible control loop, a second loop with respect to tension (the first loop is for the circuit of the motor connected to the pulley) and a possible second loop for the position of the arm.

然而，應注意到，施加至該臂之力係透過一彈簧之系統、及一藉電動步進馬達驅動之可動台車處理，該電動步進馬達係用於改變槓桿之支點、及因此該電動馬達施加於金屬線上之力。 However, it should be noted that the force applied to the arm is handled by a spring system and a movable trolley driven by an electric stepper motor for changing the fulcrum of the lever, and thus the electric motor The force applied to the wire.

甚至，在本先前文件中，針對以上提及之歐洲專利案第EP2262940號中所述系統指出的問題仍然適用。 Even in the present document, the problems pointed out by the system described in the above mentioned European Patent No. EP 2 262 940 still apply.

事實上，補償該裝置之金屬線的張力峰值及鬆弛的能力、即國際專利申請案第WO2013/064879號之標的，係與該系統之動態(彈簧力、移動台車及馬達)及該補償臂在角扇區內移動之幅度密切相關。 In fact, the ability to compensate for the peak tension and slack of the wire of the device, that is, the subject of International Patent Application No. WO 2013/064879, is related to the dynamics of the system (spring force, moving trolley and motor) and the compensating arm The magnitude of the movement within the angular sector is closely related.

又，甚至在該先前文件中，該補償臂實際上操作如一天平且該彈簧之力自動地調整而使該彈簧之力能夠補償被饋送金屬線之張力，以保持該彈簧之終端部件處於該移動之角扇區的中心。 Also, even in this prior document, the compensating arm actually operates as a day and the force of the spring is automatically adjusted to enable the force of the spring to compensate for the tension of the fed wire to maintain the end member of the spring in the movement The center of the corner sector.

最後，特別地在鬆弛階段期間之補償能力係與該補償臂之長度及該角扇區之幅度密切連結；該能力因此受限。 Finally, the compensation capability, particularly during the relaxation phase, is closely linked to the length of the compensation arm and the amplitude of the angular sector; this ability is therefore limited.

除此以外，該已知饋送器裝置不可分離地併入該補償器手段。結果為一具有非微小尺寸的沉重總成。 In addition to this, the known feeder device is inseparably incorporated into the compensator means. The result is a heavy assembly with a non-micro size.

本發明之目的係提供一種控制不連續饋送紗線之饋送的方法及系統，其包括一紗線饋送器，該紗線饋送器與一補償藉紡織機器所捲取紗線中之改變的裝置相關聯。 It is an object of the present invention to provide a method and system for controlling the feeding of discontinuous feed yarns comprising a yarn feeder associated with a means for compensating for changes in the yarn being wound by the spinning machine Union.

特別地，本發明之目的係提供一種上述型式之具有補償器裝置的系統，該補償器裝置係當饋送紗線到一紡織機器時***一控制迴路(關於饋送帶輪之速度來量測張力)中，這將克服現存解決方案之限制。 In particular, it is an object of the present invention to provide a system of the above type having a compensator device for inserting a control loop (measuring the tension with respect to the speed of the feed pulley) when feeding the yarn to a textile machine. This will overcome the limitations of existing solutions.

本發明之另一目的係提供一種上述型式之方法，該方法可主動或動態地補償，在前述不連續饋送到該紡織機器期間、在饋送紗線到該紡織機器期間及從該紡織機器移除紗線的二階段期間，在此等階段期間此類饋送被中斷，紗線所承受的任何張力改變。 Another object of the present invention is to provide a method of the above type which can be actively or dynamically compensated during the aforementioned discontinuous feeding to the textile machine, during feeding of the yarn to the textile machine, and removal from the textile machine. During the two stages of the yarn, such feeds are interrupted during these stages and any tension experienced by the yarn changes.

本發明之又一目的係提供一種適合用於上述型式之系統中的獨立補償器裝置，其不關於設定工作張力來改變動態特徵，使該裝置彈性且容易使用。 It is yet another object of the present invention to provide an independent compensator device suitable for use in a system of the above type that does not change the dynamic characteristics with respect to setting the working tension, making the device resilient and easy to use.

本發明之另一目的係提供一種上述型式之補償器裝置，其容許精確量測補償手段之位置，且亦可當紗線在不連續饋送到該紡織機器之不同階段的開始承受張力改變時，依一預測方式操作。 Another object of the present invention is to provide a compensator device of the above type which allows for accurate measurement of the position of the compensating means and also when the yarn is subjected to a change in tension at the beginning of the different stages of discontinuous feeding to the textile machine, Operate in a predictive manner.

本發明之又一目的係提供一種其小型補償器裝置，亦可作為一額外元件施加至一饋送器裝置允許該小型補償器裝置所屬之系統在鬆弛或該紡織機器反轉期間回收較已知系統可回收者多的紗線。 Yet another object of the present invention is to provide a small compensator device that can be applied as an additional component to a feeder device that allows the system to which the small compensator device belongs to recover a known system during slack or during reversal of the textile machine. More yarns that can be recycled.

熟於此技藝者將明白這些及其他目的係透過依據申請專利範圍附屬項之方法、饋送器系統、及補償器裝置達成。 Those skilled in the art will appreciate that these and other objects are achieved by a method, a feeder system, and a compensator device in accordance with the scope of the claims.

Compensator device; Figure 9 shows a view from below the compensator device in accordance with the present invention; and Figures 10A through 10C show different block diagrams for use with the system in accordance with the present invention; Figures 11A through 11C show A graph of the tension of the yarn of the textile machine, in the case where the apparatus as the target of the present invention is not operated (Fig. 11A), and the system according to the present invention is in a passive-dynamic mode (Fig. 11B) and initiative- Where the two measurement mode (FIG. 11C) operation.

請參考前述圖式(其中對應的部件具有相同的數字參考符號)，特別是第1圖，依據本發明之一補償器裝置大體上以1標示，且與本身已被熟知的一饋送器裝置或簡稱一饋送器2，之一末端2A相關聯(或位於該饋送器之一側上)以依固定張力饋送一紗線F(在第1圖中以虛線顯示)到一紡織機器T。紗線F亦可為一金屬線，且可輸送到譬如一捲線機之一操作機器。對比於饋送器2，裝置1在結構及使用二者上，皆為一完整且可清楚識別的元件。 Please refer to the foregoing drawings (in which the corresponding components have the same numerical reference numerals), in particular, FIG. 1 , a compensator device according to the invention is generally indicated at 1, and is associated with a feeder device or Referring to a feeder 2, one end 2A is associated (or on one side of the feeder) to feed a yarn F (shown in phantom in Figure 1) to a textile machine T in accordance with a fixed tension. The yarn F can also be a wire and can be conveyed to a machine such as a winder. In contrast to the feeder 2, the device 1 is a complete and clearly identifiable component both in construction and in use.

饋送器2具有一張力感測器3、一帶輪4(或等效的紗線積蓄手段)及一控制單元或電子裝置60，該帶輪藉其本身之電動馬達(未顯示)驅動，該控制單元較佳地具有本身已被熟知的微處理器(請參見第10A圖至第10C圖)。當一紗線被饋送到該紡織機器時，該控制單元或電子裝置能夠估算被感測器3偵測到之該紗線的張力、將該偵測到的張力與一既定值(或設定點數值)比較、以及透過於該電動馬達上及因此帶輪4上的作用檢查及調整該紗線之張力(倘該紗線之張力不同於期望數值)。該饋送器2及其部件3、4係已知的型式及操作，因此將不進一步說明。 The feeder 2 has a force sensor 3, a pulley 4 (or equivalent yarn accumulation means) and a control unit or electronic device 60, which is driven by its own electric motor (not shown), the control The unit preferably has a microprocessor that is well known per se (see Figures 10A through 10C). When a yarn is fed to the textile machine, the control unit or electronic device can estimate the tension of the yarn detected by the sensor 3, and the detected tension and a predetermined value (or set point) The value is compared and the tension of the yarn is checked and adjusted by the action on the electric motor and thus on the pulley 4 (if the tension of the yarn is different from the desired value). The feeder 2 and its components 3, 4 are of a known type and operation and will therefore not be further described.

已述及的饋送器使該紗線以固定張力饋送到該紡織機器，該紡織機器係用於製品之一生產單元、或用於處理該紗線之一機器。 The feeder described has fed the yarn to the textile machine at a fixed tension, which is used in one of the production units of the article, or a machine for processing the yarn.

依據本發明，裝置1及饋送器2界定用於紗線F之饋送系統。 According to the invention, the device 1 and the feeder 2 define a feed system for the yarn F.

依據本發明之補償器裝置1能夠在紗線已越過帶輪4後，與該紗線共同作用。因此該補償器裝置在紗線張力控制迴路內，這可從第1圖看出且將由依據本發明之方法的說明而明白。基於本發明，可能增加該饋送器系統之動態性能，使得該饋送器系統能夠立即補償紗線捲取中之突然改變(正或負)，允許帶輪馬達依新捲取狀態之需求而改變成新速度來饋送紗線，不致造成最終紗線張力中之正或負張力峰值。 The compensator device 1 according to the invention can interact with the yarn after the yarn has passed the pulley 4. The compensator device is thus within the yarn tension control loop, as can be seen from Figure 1 and will be understood by the description of the method according to the invention. Based on the present invention, it is possible to increase the dynamic performance of the feeder system such that the feeder system can immediately compensate for sudden changes (positive or negative) in the yarn take-up, allowing the pulley motor to be changed to the need for a new take-up state. The new speed feeds the yarn without causing a positive or negative tension peak in the final yarn tension.

控制迴路內補償器裝置1之存在，恆確保離開饋送器2之紗線的張力恆與設定者相同。 The presence of the compensator device 1 within the control loop ensures that the tension of the yarn exiting the feeder 2 is always the same as the setter.

對比於饋送器2補償器1係一獨立裝置，且包括一電動馬達8，該電動馬達譬如為一直流電刷馬達，較佳地具有非常低的慣量以增強其動態。在作為範例之本發明具體實施例中，馬達8直接移動一驅動軸，該驅動軸具有從該馬達本身的兩相側凸出的二部件。在圖式中，該驅動軸之第一部件係以7標示(請參見第7圖至第9圖)，且以10標示的第二部件可在第9圖中看出；該馬達亦***該裝置之一本體11內。一剛性臂13(因此附接至該驅動軸本身)係以機械式附接至該驅動軸之第一部。臂13之一末端14處亦有一陶瓷(或其他材料)環形本體(或一其他外型)16，紗線係於該環形本體上運行。 The compensator 1 is a separate device compared to the feeder 2 and includes an electric motor 8, such as a DC brush motor, preferably having a very low inertia to enhance its dynamics. In a specific embodiment of the invention as an example, the motor 8 directly moves a drive shaft having two members projecting from the two-phase side of the motor itself. In the drawings, the first part of the drive shaft is indicated by 7 (see Figures 7 to 9), and the second part indicated at 10 can be seen in Figure 9; the motor is also inserted One of the devices is in the body 11. A rigid arm 13 (and thus attached to the drive shaft itself) is mechanically attached to the first portion of the drive shaft. Also at one end 14 of the arm 13 is a ceramic (or other material) annular body (or other outer shape) 16 on which the yarn runs.

已述及之電動馬達8較佳地具有非常低的慣量，以容許臂13在紗線之力下快速移動，且因此快速補償此移動而不致造成紗線本身中之張力峰值。 The electric motor 8 already mentioned preferably has a very low inertia to allow the arm 13 to move rapidly under the force of the yarn and thus quickly compensate for this movement without causing a tension peak in the yarn itself.

然而，當該馬達具有非常低的慣量(較佳者)且當臂13具有有限的慣量時，倘由紗線F拖拉該臂，則該臂可環繞一軸線M(或驅動軸之軸線)自由地旋轉(造成該馬達旋轉)；在每一情況下，該臂皆具有一零或初始休止位置(譬如在第6圖中看出者)，這係當紗線F被紡織機器T捲取而無張力改變且無中斷時採用。該臂亦可採取其他補償位置，如以下說明者。 However, when the motor has a very low inertia (better) and when the arm 13 has a limited inertia, if the arm is pulled by the yarn F, the arm can be free about an axis M (or the axis of the drive shaft). Ground rotation (causing the motor to rotate); in each case, the arm has a zero or initial rest position (as seen in Figure 6), when the yarn F is taken up by the textile machine T Used without tension change and without interruption. The arm can also take other compensation positions, as explained below.

臂13與馬達8之總成(即，實質係裝置1)可操作於二不同模式：被動-動態模式或主動-預測模式。 The assembly of arm 13 and motor 8 (i.e., substantial system 1) is operable in two different modes: passive-dynamic mode or active-prediction mode.

在被動-動態模式中，該馬達允許臂13(附接至該驅動軸)被紗線拉動且從其休止位置移動而亦造成該馬達本身旋轉。然而，該馬達在此移動後作用，以使臂13返回該休止位置。在本模式或操作模式下，該馬達大致操作如一「動態」彈簧，可藉程式化及/或控制馬達扭矩來將該馬達之力(該馬達作用於臂13上者)程式化。 In the passive-dynamic mode, the motor allows the arm 13 (attached to the drive shaft) to be pulled by the yarn and moved from its rest position, which also causes the motor itself to rotate. However, the motor acts after this movement to return the arm 13 to the rest position. In this mode or mode of operation, the motor operates generally as a "dynamic" spring that can be programmed to and/or control the motor torque to program the force of the motor (which acts on the arm 13).

然而，該力並非既定且固定(如同在美國專利案第US4752044號中之解決方案)，但是可變化，因為該力可自動地調整以改變在生產程序之各階段中紗線張力設定值，以便恆保持該臂於其既定位置，無論生產製品之每一特殊階段的紗線設定操作張力為何。這將使馬達8能夠以一相等且相反之力對抗使臂13(該馬達恆直接連接至該臂)從該休止位置移動之力，而保持該臂於其平衡位置(譬如第6圖中的「3點鐘」處)。 However, this force is not intended and fixed (as in the solution of US Pat. No. 4,752,044), but can vary, as the force can be automatically adjusted to change the yarn tension setting during each stage of the production process so that The arm is kept in its intended position regardless of the yarn setting operation tension at each particular stage of the product being produced. This will enable the motor 8 to counteract the force that moves the arm 13 (which is permanently connected directly to the arm) from the rest position with an equal and opposite force, while maintaining the arm in its equilibrium position (such as in Figure 6). "3 o'clock").

以下將說明該馬達對臂13之對抗力或作用的可變性。 The variability of the opposing force or action of the motor to the arm 13 will be explained below.

在主動-預測模式下，馬達8一偵測到由於該機器之操作階段的改變所致之一紗線張力改變(藉感測器3偵測)時，即能夠預先依「預測模式」作用。在這種情況下，馬達8將由該驅動軸所承載之臂13移動至能夠補償該張力改變的補償位置：倘該張力改變傾向於增加，則馬達8將該臂移動至第7圖中「6點鐘」處之補償位置，倘該改變傾向於一紗線張力減小(由於該紡織機器已停止或減慢紗線捲取)，則該馬達將臂13移動至第8圖中「12點鐘」處之補償位置。如此，不論紡織機器T之操作及生產階段，皆可保持固定的紗線張力。 In the active-prediction mode, when the motor 8 detects a change in the yarn tension (detected by the sensor 3) due to a change in the operating phase of the machine, it can act in advance in the "predictive mode". In this case, the motor 8 moves the arm 13 carried by the drive shaft to a compensation position capable of compensating for the change in tension: if the tension change tends to increase, the motor 8 moves the arm to "6" in Fig. 7. The compensation position at the "clock", if the change tends to decrease the yarn tension (because the textile machine has stopped or slowed the yarn take-up), the motor moves the arm 13 to "12 points" in Fig. 8. The compensation position at the clock. In this way, a constant yarn tension can be maintained regardless of the operation and production stage of the textile machine T.

第11A圖至第11C圖顯示各種狀態的張力曲線，分別為馬達-臂總成或裝置1失效(第11A圖)、被動-動態模式(第11B圖)或主動-預測模式(第11C圖)。 Figures 11A through 11C show tension curves for various states, motor-arm assembly or device 1 failure (Figure 11A), passive-dynamic mode (Figure 11B), or active-prediction mode (Figure 11C). .

在此等圖式中，曲線或線F、K、W及Y分別界定出設定紗線張力(生產操作階段中，曲線F)、量測之紗線張力(曲線K)、臂13之設定點位置(曲線W)及臂13之實際位置(曲線Y)。在此等圖式中，時間為橫坐標，縱坐標為量測F與K之張力以及W與Y之位置值。 In these figures, the curves or lines F, K, W, and Y define the set yarn tension (curve F during the production operation phase), the measured yarn tension (curve K), and the set point of the arm 13 Position (curve W) and actual position of the arm 13 (curve Y). In these figures, the time is the abscissa and the ordinate is the tension between F and K and the position values of W and Y.

可由比對圖式看出，當裝置1失效時，量測之紗線張力相較於第11B圖及第11C圖中其他狀態具有顯著峰值及變動。亦可由比對第11B圖及第11C圖看出，在裝置1以主動-預測模式作用的狀態下，紗線張力具有較為有限的變動。最後，可在第11C圖中看出，臂 13之休止位置(曲線W)並非既定，而係跟隨紗線張力而改變；在裝置1執行補償期間，此休止位置亦被該臂之「當前」位置「跟隨」。 As can be seen from the comparison pattern, when the device 1 fails, the measured yarn tension has significant peaks and variations compared to the other states in FIGS. 11B and 11C. It can also be seen from the comparison of Fig. 11B and Fig. 11C that the yarn tension has a relatively limited variation in the state in which the device 1 is operated in the active-prediction mode. Finally, it can be seen in Fig. 11C that the rest position (curve W) of the arm 13 is not predetermined but changes in accordance with the yarn tension; during the execution of the compensation by the device 1, the rest position is also "current" by the arm. The location "follows".

該驅動軸之第二部10支持一磁鐵18，該磁鐵連同與馬達8相關連之臂13可繞其軸線M在一特定圓扇形內自由旋轉(造成該驅動軸旋轉)。另一選擇為，包括臂13及磁鐵18之總成可自由地旋轉，而達成一繞旋轉軸線M(該驅動軸之軸線)的完整迴轉；換言之，臂13與磁鐵18二者皆開栓槽於該驅動軸上，造成二者皆繞軸線M依相同方式、即自由地或在一角扇區內旋轉。如此將使臂13之位置能夠藉偵測該磁鐵之位置而立即得知。 The second portion 10 of the drive shaft supports a magnet 18 which, along with the arm 13 associated with the motor 8, is free to rotate about its axis M in a particular circular sector (causing the drive shaft to rotate). Alternatively, the assembly including the arm 13 and the magnet 18 can be freely rotated to achieve a complete revolution about the axis of rotation M (the axis of the drive shaft); in other words, both the arm 13 and the magnet 18 are slotted. On the drive shaft, both are rotated about the axis M in the same manner, ie freely or within an angular sector. This will enable the position of the arm 13 to be immediately known by detecting the position of the magnet.

為此目的，具有圍繞該磁鐵的位置偵測器，譬如一個或更多個線性霍爾感測器20，其能夠生成一位置訊號，該位置訊號被送至譬如補償器裝置1之一控制單元70。基於該霍爾感測器資料，該單元70能夠轉換馬達旋轉成二個偏移90°之正弦曲線(正弦與餘弦)。由此，可能即時取得該轉軸、及因此臂13之絕對位置，其中該臂係與紗線共同作用，臂13係剛性地附接至該轉軸及磁鐵18。 For this purpose, there is a position detector surrounding the magnet, such as one or more linear Hall sensors 20, which are capable of generating a position signal which is sent to a control unit such as one of the compensator devices 1. 70. Based on the Hall sensor data, the unit 70 is capable of switching the motor to a sinusoidal (sine and cosine) offset by two degrees. Thereby, it is possible to obtain the absolute position of the shaft, and thus the arm 13, in real time, wherein the arm system cooperates with the yarn, and the arm 13 is rigidly attached to the shaft and the magnet 18.

在某一具體實施例中，該控制單元亦較優地包括數個系統(其本身已被熟知)來驅動該電動馬達，以控制該馬達之轉速及施加的扭矩。 In a specific embodiment, the control unit preferably also includes a plurality of systems (which are known per se) to drive the electric motor to control the speed of the motor and the applied torque.

較佳地，亦提供在饋送器2之控制電子裝置60與補償器裝置1之控制單元70之間的即時資料交換，以便能夠為該裝置1之馬達設定期望的扭矩，且接著控制該馬達之旋轉及讀取該馬達之位置(及結果依一直接且立即之方式來控制臂13之位置)。因為扭矩設定值取決於設定紗線張力、或藉感測器3偵測之紗線張力，故呈動態且非固定的。 Preferably, an instant data exchange between the control electronics 60 of the feeder 2 and the control unit 70 of the compensator device 1 is also provided to enable the desired torque to be set for the motor of the device 1 and then to control the motor Rotate and read the position of the motor (and the result controls the position of the arm 13 in a direct and immediate manner). The torque setting is dynamic and non-fixed because it depends on the set yarn tension or the yarn tension detected by the sensor 3.

資訊交換可依以下方式其中之一產生：透過任何串列匯流排、透過數位或脈波寬度調變(PWM)訊號、或透過類比訊號。 Information exchange can occur in one of the following ways: through any serial bus, through digital or pulse width modulation (PWM) signals, or through analog signals.

因此，與該補償器裝置1共同作用之饋送器2(透過該饋送器之控制電子裝置)顯然能夠依一可靠且立即之方式即時得知臂13之位置，以及調整被施加至補償器裝置1之馬達的扭矩/偏移/速度。這係因該驅動軸與該臂之直接連接、或因該馬達對該臂之直接作用所致。 Therefore, the feeder 2 (via the control electronics of the feeder) cooperating with the compensator device 1 can clearly know the position of the arm 13 in a reliable and immediate manner, and the adjustment is applied to the compensator device 1 Torque/offset/speed of the motor. This is due to the direct connection of the drive shaft to the arm or the direct action of the motor on the arm.

藉適當地處理該接收到的臂13位置訊號及適當地控制作用於該臂上之馬達，因此依據本發明，紗線F的饋送器系統能夠以一幾乎立即之方式來閉合一用於臂13之位置的第二控制迴路，而當設定張力變化時，保持該臂於期望之位置、譬如該臂之中心位置(「3點鐘」)。這係為了補償與紡織機器之各操作階段連結的紗線移動及紗線張力改變。 By properly processing the received position signal of the arm 13 and appropriately controlling the motor acting on the arm, the feeder system of the yarn F can be closed for an arm 13 in an almost immediate manner in accordance with the present invention. The second control loop at the position, while maintaining the tension change, maintains the arm at a desired position, such as the center of the arm ("3 o'clock"). This is to compensate for yarn movement and yarn tension changes associated with the various stages of operation of the textile machine.

請參考第10A圖及第10B圖，可依不同方式來實現該系統： Please refer to Figure 10A and Figure 10B. The system can be implemented in different ways:

1.補償器裝置1具有其本身之控制單元70，該控制單元欲接收從饋送器2之控制電子裝置60來的一休止位置參考點(在第10A圖及第10B圖中以方塊80標示)，在紗線F之設定張力或偵測張力變化時，該臂必須保持該休止位置參考點。控制單元70與該手段(磁鐵18)共同作用，以量測臂13及驅動馬達8之位置(方塊81及82)。是以，該控制單元將用於臂13之位置的控制迴路閉合。 1. The compensator device 1 has its own control unit 70, which is intended to receive a rest position reference point from the control electronics 60 of the feeder 2 (indicated by block 80 in Figures 10A and 10B) The arm must maintain the rest position reference point when the tension of the yarn F is set or the tension is detected. Control unit 70 cooperates with the means (magnet 18) to measure the position of arm 13 and drive motor 8 (blocks 81 and 82). Therefore, the control unit closes the control loop for the position of the arm 13.

2.另一選擇且較佳地，饋送器2之控制電子裝置60，其從磁鐵18接收有關臂13之位置的資料，且結果設定馬達8之扭矩值，以閉合用於該位置之控制迴路(基於設定的紗線張力或偵測到的紗線張力)。在這種情況下，用於馬達8之驅動手段可位於補償器裝置1之控制單元70中(參考點係藉該饋送器而傳遞至該控制單元)，或位於補償器2之電子裝置60中(如以下所述者)。由於饋送器2之控制電子裝置60不僅知道該臂之位置，且亦直接得知紗線之量測張力(連接至張力感測器3)，以及接著可使用該二項資訊來最佳化該系統之性能，因此本解決方案為最佳者。例如，倘此類電子裝置偵測到紗線張力因來自紡織機器T的突然紗線需求而增加，則該等電子裝置可決定譬如藉移動臂13之位置設定點從「3點鐘」到「6點鐘」，而自動地改變該臂之位置設定點。這係依據馬達8及臂13之總成的主動-預測模式，如以上指示者。 2. Alternatively and preferably, the control electronics 60 of the feeder 2 receives information about the position of the arm 13 from the magnet 18 and, as a result, sets the torque value of the motor 8 to close the control loop for that position (based on the set yarn tension or the detected yarn tension). In this case, the driving means for the motor 8 can be located in the control unit 70 of the compensator device 1 (the reference point is transmitted to the control unit by the feeder) or in the electronic device 60 of the compensator 2 (as described below). Since the control electronics 60 of the feeder 2 not only knows the position of the arm, but also directly knows the measured tension of the yarn (connected to the tension sensor 3), and can then use the two pieces of information to optimize the The performance of the system, so this solution is the best. For example, if such an electronic device detects that the yarn tension is increased by the sudden yarn demand from the textile machine T, the electronic device may determine, for example, from the "3 o'clock" to the "set point" of the moving arm 13 At 6 o'clock, the position set point of the arm is automatically changed. This is based on the active-prediction mode of the assembly of motor 8 and arm 13, as indicated above.

由於不僅利用馬達8之低慣量，且亦利用其動態，來補償狀態，因此該功能亦容許進一步降低峰值張力。同樣的，這明顯地也可應用至捲取突然減慢的階段。事實上，這全部皆可由第11C圖、及先前所述第11B 圖的比對看出。 This function also allows the peak tension to be further reduced by not only utilizing the low inertia of the motor 8, but also using its dynamics to compensate for the state. Again, this can obviously be applied to the stage where the take-up is suddenly slowed down. In fact, all of this can be seen by the comparison of Figure 11C and the previously described Figure 11B.

該饋送器系統之電子裝置(即，補償器裝置1之控制單元70或饋送器2之電子裝置60，如上述者)藉持續讀取臂13之位置(取決於在紗線F中偵測到之張力)且藉適當地控制該馬達與臂13共同作用之扭矩，而能夠保持補償臂13之位置於期望之數值。因此此扭矩值將藉直接透過該驅動軸施加一相等且相反於紗線饋送張力之力至該臂，而容許臂13在譬如3點鐘處之其休止位置中保持平衡。如此，對臂13之作用將無任何延遲，此延遲會而在國際專利案第WO2013/064879號解決方案中發生。 The electronic device of the feeder system (i.e., the control unit 70 of the compensator device 1 or the electronic device 60 of the feeder 2, as described above) continues to read the position of the arm 13 (depending on the detection in the yarn F) The tension) and by appropriately controlling the torque of the motor and the arm 13, can maintain the position of the compensating arm 13 at a desired value. Thus, this torque value will allow the arm 13 to be balanced in its rest position, such as at 3 o'clock, by applying a force equal to the yarn feed tension directly to the arm through the drive shaft. Thus, there will be no delay in the action of the arm 13, which will occur in the solution of International Patent Application No. WO 2013/064879.

是以，紗線張力增加或減少將造成臂13從其平衡位置移動，恆保持紗線於設定工作張力，如下所表示之範例： Therefore, an increase or decrease in the yarn tension will cause the arm 13 to move from its equilibrium position, keeping the yarn at a set working tension, as exemplified by:

a)在處理期間，在所當設定的紗線張力需要增加的情況下，臂13將明顯地傾向落下(在第7圖中朝「6點鐘」位置移動)，且讀取此位置改變之系統電子裝置(即，裝置1之控制單元70或饋送器2之控制電子裝置60)將計算待施加至馬達8之新扭矩，以將臂13帶回該休止位置。 a) During the processing, in the case where the set yarn tension needs to be increased, the arm 13 will obviously tend to fall (moving toward the "6 o'clock position" in Fig. 7), and reading this position change The system electronics (i.e., control unit 70 of device 1 or control electronics 60 of feeder 2) will calculate the new torque to be applied to motor 8 to bring arm 13 back to the rest position.

b)在處理期間，在所設定的張力需要減少的情況下，臂13將明顯地傾向升起(在第8圖中朝「12點鐘」位置移動)，且讀取此位置改變之饋送器的控制單元或電子裝置將計算待施加至馬達8之新扭矩，以將臂13帶回該休止位置。 b) During the processing, in the case where the set tension needs to be reduced, the arm 13 will obviously rise (to move toward the "12 o'clock position" in Fig. 8), and the feeder for reading the position change is read. The control unit or electronic device will calculate the new torque to be applied to the motor 8 to bring the arm 13 back to the rest position.

因此，該等饋送器電子裝置將因補償臂13附接至該驅動軸，而能夠自動地且快速地、精確地控制該臂之位置，如此使操作員在操作期間隨意修改工作張力，譬如在製品的生產循環期間達成張力分級(例如，醫療襪上之分級壓縮等)。張力的每一改變皆牽涉到施加於臂13之馬達扭矩的改變，該臂將恆採取該休止位置(譬如「3點鐘」)、或將被帶回該休止位置，以保持紗線「當前」張力於恒定、或紗線在特定生產階段所需之特定饋送階段期間捲取的張力。 Thus, the feeder electronics will be able to automatically and quickly and accurately control the position of the arm by attaching the compensating arm 13 to the drive shaft, thus allowing the operator to arbitrarily modify the working tension during operation, such as in Tension grading is achieved during the production cycle of the article (eg, graded compression on medical socks, etc.). Each change in tension involves a change in the torque applied to the arm 13 that will either take the rest position (such as "3 o'clock") or will be brought back to the rest position to maintain the yarn "currently The tension is constant, or the tension of the yarn being taken during a particular feeding phase required for a particular production phase.

換言之，該饋送器系統設有一控制單元(裝置1或饋送器2)，該控制系統併入譬如一微處理器，用於控制該馬達之操作，該馬達直接移動臂13。然而，當該紡織機器之捲取或饋送狀態變化，使通過臂13所支持之環形本體16的紗線之張力跟隨改變時，該臂連同該臂所連接之驅動軸可在初始時繞軸線M自由地移動(造成該馬達旋轉)。 In other words, the feeder system is provided with a control unit (device 1 or feeder 2) that incorporates, for example, a microprocessor for controlling the operation of the motor, which directly moves the arm 13. However, when the winding or feeding state of the textile machine changes such that the tension of the yarn of the annular body 16 supported by the arm 13 follows, the arm and the drive shaft to which the arm is coupled can be initially around the axis M. Move freely (causing the motor to rotate).

臂13之位置的任何改變(關於一既定參考點或休止位置，譬如「3點鐘」)，係透過來自位置偵測手段19之訊號由該饋送器系統之控制單元偵測到。這些資料被供應至該電子控制單元(60、70)，由該饋送器系統來閉合控制迴路。 Any change in the position of the arm 13 (with respect to a predetermined reference point or rest position, such as "3 o'clock") is detected by the control unit of the feeder system via the signal from the position detecting means 19. These data are supplied to the electronic control unit (60, 70) by which the control loop is closed.

特別地，裝置1之控制單元70能夠偵測臂13已從參考位置移動多少(角度)，且饋送器2之控制電子裝置60可基於此數值來監視、改變及控制送至帶輪4之馬達的電源供應，使得該馬達改變該馬達之轉速，以補償臂13關於該參考位置之角移動。如此，饋送器2利用關於臂13之位置的資訊來預期改變(帶輪4之加速/減速)，進一步改善輸送張力之品質。這係依據上述之「主動-預測」操作模式。 In particular, the control unit 70 of the device 1 is capable of detecting how much (angle) the arm 13 has moved from the reference position, and the control electronics 60 of the feeder 2 can monitor, change and control the motor sent to the pulley 4 based on this value. The power supply is such that the motor changes the speed of the motor to compensate for the angular movement of the arm 13 about the reference position. Thus, the feeder 2 utilizes information on the position of the arm 13 to anticipate a change (acceleration/deceleration of the pulley 4), further improving the quality of the conveying tension. This is based on the "active-predictive" mode of operation described above.

亦在這種情況下(如同在歐洲專利案第EP2262940號之情況下)，因此補償器裝置1作用如一「天平」，且該饋送器系統之電子裝置將即時計算待施加至馬達8之扭矩，該馬達與臂13共同作用，以依一完全自動的方式恆保持該臂處於平衡。這取決於紗線F之「當前」張力(明顯地保持既定張力)。 Also in this case (as in the case of European Patent No. EP2262940), the compensator device 1 acts as a "balance" and the electronic device of the feeder system will instantaneously calculate the torque to be applied to the motor 8, The motor cooperates with the arm 13 to constantly maintain the arm in equilibrium in a fully automated manner. This depends on the "current" tension of the yarn F (obviously maintaining a given tension).

依此方式控制臂13之位置，亦將對輸送張力具有補償效果，這將導致完全消除或大幅減少紗線本身之張力峰值及鬆弛。事實上，當紡織機器T突然增加對紗線F之需求，且馬達驅動帶輪4之動態不足以補償此改變時，臂13將傾向落下(朝「6點鐘」位置移動)而增加送至機器T之紗線F量；此增加直到帶輪4之馬達到達消除或減少張力峰值的必需轉速為止。此時，該臂將自動地返回其初始或休止位置。 Controlling the position of the arm 13 in this manner will also have a compensating effect on the transport tension which will result in complete elimination or substantial reduction in the tension peak and slack of the yarn itself. In fact, when the textile machine T suddenly increases the demand for the yarn F, and the dynamics of the motor drive pulley 4 is insufficient to compensate for this change, the arm 13 will tend to fall (moving toward the "6 o'clock" position) and increase the delivery to The amount of yarn F of machine T; this increase until the motor of pulley 4 reaches the necessary speed to eliminate or reduce the peak tension. At this point, the arm will automatically return to its initial or rest position.

相反地，當該紡織機器突然減少對紗線之需求，且馬達驅動帶輪4之動態不足以補償此改變時，臂13將傾向升起(朝第8圖中「12點鐘」方向移動)而減少送至機器T之紗線F量，直到帶輪4之馬達到達消除或減少紗線鬆弛的必需轉速為止。此時，該臂將自動地返回其初始或休止位置(第6圖)。 Conversely, when the textile machine suddenly reduces the need for yarn and the dynamics of the motor drive pulley 4 is insufficient to compensate for this change, the arm 13 will tend to rise (moving toward "12 o'clock" in Figure 8) The amount of yarn F sent to the machine T is reduced until the motor of the pulley 4 reaches the necessary rotational speed to eliminate or reduce the slack of the yarn. At this point, the arm will automatically return to its initial or rest position (Figure 6).

在第一具體實施例中，臂13之休止位置係位於補償手段或臂13之一移動範圍內，該範圍具有二個限制位置(即，6點鐘及12點鐘)。 In the first embodiment, the rest position of the arm 13 is within the range of movement of the compensation means or arm 13, which has two restricted positions (i.e., 6 o'clock and 12 o'clock).

又者，精確且即時地得知補償臂13之位置，使饋送器2之電子裝置可使用其資訊來加速或減慢帶輪4之旋轉，以將安定至新理想速度以取得固定的紗線F張力預設值且保持該值之時間最小化，而進一步限制紗線F中之張力峰值之振幅或鬆弛。 Moreover, the position of the compensating arm 13 is accurately and immediately known, so that the electronic device of the feeder 2 can use its information to accelerate or slow the rotation of the pulley 4 to stabilize to a new ideal speed to obtain a fixed yarn. The F tension preset value and the time to maintain the value are minimized, and the amplitude or slack of the tension peak in the yarn F is further limited.

又者，在暫態(捲取改變)期間透過感測器3精確且即時地得知補償臂13之位置、及量測之張力值，使該餵送器系統可改變與臂13共同作用之馬達8的驅動，以更降低饋送器2之輸送張力的改變；譬如：(i)在突然加速階段期間，臂13將傾向落下(朝第7圖中「6點鐘」補償位置移動)且量測之紗線張力將傾向升起；在這種情況下，該饋送器系統之電子裝置可決定：1)中斷控制臂13位置之迴路的閉合、或降低該迴路之影響，以便紗線可降下臂13直到紗線張力在既定限值內為止，因此使用該間隔，以便當一紗線F存料將被饋送時，從3點鐘移動到6點鐘；2)自動地設定臂13之工作設定點到一較低位置，以提供較多紗線F給紡織機器T，直到克服臨界狀態為止。 Moreover, during the transient (winding change), the position of the compensation arm 13 and the measured tension value are accurately and instantaneously transmitted through the sensor 3, so that the feeder system can change the interaction with the arm 13. The motor 8 is driven to further reduce the change in the conveying tension of the feeder 2; for example: (i) during the sudden acceleration phase, the arm 13 will tend to fall (moving toward the "6 o'clock" compensation position in Fig. 7) The measured yarn tension will tend to rise; in this case, the electronics of the feeder system may determine: 1) interrupt the closing of the circuit at the position of the control arm 13, or reduce the effect of the circuit so that the yarn can be lowered The arm 13 is until the yarn tension is within the predetermined limits, so the interval is used to move from 3 o'clock to 6 o'clock when a yarn F stock is to be fed; 2) automatically set the work of the arm 13 Set the point to a lower position to provide more yarn F to the textile machine T until the critical state is overcome.

(ii)在突然減速階段期間，臂13將傾向升起(移動到第8圖中「12點鐘」補償位置)且量測之張力將傾向落下；在這種情況下，該饋送器系統可決定： 1)中斷位置控制迴路之閉合、或降低該迴路之影響，以便臂13可回收紗線F直到該紗線之張力處於既定限值內為止，因此使用該間隔以便從3點鐘移動到12點鐘，以作用來回收過量的饋送紗線；2)自動地設定臂13之工作設定點或休止位置到一較高位置，以提供較少紗線F給紡織機器T，直到克服臨界狀態為止。 (ii) during the sudden deceleration phase, the arm 13 will tend to rise (move to the "12 o'clock" compensation position in Figure 8) and the measured tension will tend to fall; in this case, the feeder system can Decide: 1) interrupt the closing of the position control loop or reduce the effect of the loop so that the arm 13 can recover the yarn F until the tension of the yarn is within the established limits, so the interval is used to move from 3 o'clock to At 12 o'clock, the excess feed yarn is recovered by action; 2) the working set point or rest position of the arm 13 is automatically set to a higher position to provide less yarn F to the textile machine T until the critical state is overcome until.

到目前為止，譬如考慮為「3點鐘」值(第6圖)，則補償臂13之位置控制迴路的設定點或參考值可能是可變的，且藉該饋送器電子裝置適當地動態處理，以便(譬如)提供給一可能的接續饋送階段；例如，在紗線藉該紡織機器減慢且接著停止的階段期間，該設定點可自動地推移至12點鐘位置，使得有較大的紗線F存量在重新啟動時提供給下次加速，而進一步降低下次峰值。 So far, for example, considering the "3 o'clock" value (Fig. 6), the set point or reference value of the position control loop of the compensating arm 13 may be variable and dynamically processed by the feeder electronics. In order to provide, for example, a possible successive feeding phase; for example, during the phase in which the yarn is slowed down and then stopped by the textile machine, the set point can be automatically shifted to the 12 o'clock position, so that there is a larger The yarn F inventory is provided to the next acceleration upon restart, and further reduces the next peak.

在本發明之又一具體實施例(業已包含於圖式)中，亦有與補償臂13相關聯之一鼓輪或圓筒26，紗線係在回收階段期間存儲於該鼓輪或圓筒上，因此將因角旋轉扇區之幅度已增加而增加紗線F之貯存量，且在這種情況下，將不再受限於6點鐘與12點鐘之間，但將能夠繞旋轉軸線M自由地旋轉。 In yet another embodiment of the invention (which is already included in the drawings), there is also a drum or cylinder 26 associated with the compensating arm 13, the yarn being stored in the drum or cylinder during the recovery phase. Above, therefore, the amount of yarn F stored will increase due to the increase in the amplitude of the angular rotation sector, and in this case, will no longer be limited between 6 o'clock and 12 o'clock, but will be able to rotate around The axis M is free to rotate.

紗線存儲所在之該鼓輪可附接至臂13或在可使該鼓輪之旋轉獨立的軸承上自由旋轉。該鼓輪之直徑決定了可從裝置1/饋送器2系統之最大紗線F量。該鼓輪可因此具有不同尺寸，此等尺寸取決於期望回收至該鼓輪上之紗線F量。該鼓輪可呈圓柱形、半圓柱形、或呈具有可變剖面之外型。 The drum on which the yarn is stored can be attached to the arm 13 or free to rotate on a bearing that can rotate the drum independently. The diameter of the drum determines the maximum amount of yarn F that can be obtained from the device 1 / feeder 2 system. The drums can thus have different sizes depending on the amount of yarn F that is desired to be recycled to the drum. The drum may be cylindrical, semi-cylindrical, or of a variable profile.

該補償器裝置可能在未設有防止該補償器裝置旋轉超越6點鐘到12點鐘弧之機械止擋的情況下工作，而容許臂13在該回收階段期間繞軸線無限制地旋轉。在這種情況下，臂13自由地存儲在回收階段期間貯存於鼓輪26上之非常大量紗線，接著將在下次重新啟動時饋送回該紡織機。 The compensator device may operate without mechanical stops preventing the compensator device from rotating beyond the 6 o'clock to 12 o'clock arc, while allowing the arm 13 to rotate unrestricted about the axis during the recovery phase. In this case, the arm 13 is free to store a very large number of yarns stored on the drum 26 during the recovery phase, which will then be fed back to the textile machine on the next restart.

如此將產生紗線的雙「貯藏器」，即除了帶輪4外還有鼓輪26。 This will create a double "reservoir" of the yarn, i.e., a drum 26 in addition to the pulley 4.

基於本發明，單一「系統」能夠以甚至極不相同之饋送張力工作，而無需操作員之任何動作。該系統能夠補償饋送中之突然改變，而不致引起張力峰值或紗線之鬆弛，以及至少能夠回收較目前技藝水準中先前所述解決方案者大量的紗線F。 Based on the present invention, a single "system" can operate with even very different feed tensions without any action by the operator. The system is capable of compensating for sudden changes in the feed without causing tension peaks or slack in the yarn, and at least capable of recovering a large number of yarns F than those previously described in the current state of the art.

已描述了本發明之各種具體實施例。當然尚可能有其他具體實施例。例如，臂13上之環形陶瓷本體可由具有滑移特徵而適於應用之任何其他材料所製成的一本體取代。除此以外，本文描述使用具有電刷之直流馬達，然明顯地可使用任何型式之電動馬達或致動器(無刷、步進等)，且亦可使用氣動者。 Various specific embodiments of the invention have been described. Of course, there may be other specific embodiments. For example, the annular ceramic body on the arm 13 can be replaced by a body made of any other material having a slip feature suitable for the application. In addition to this, the description herein uses a DC motor with a brush, but it is obvious that any type of electric motor or actuator (brushless, stepping, etc.) can be used, and pneumatics can also be used.

已描述使用一具有霍爾感測器來偵測驅動軸旋轉之編碼器，但亦可使用市場上的任何編碼器，或一霍爾感測器可併入馬達中；在這種情況下，無需使驅動軸在二側皆凸出。 An encoder having a Hall sensor to detect the rotation of the drive shaft has been described, but any encoder on the market, or a Hall sensor can be incorporated into the motor; in this case, There is no need to make the drive shaft project on both sides.

除此以外，臂13係剛性的，然而該臂可具有其本身之最小撓度，以進一步緩衝補償效果，此類撓度係源自於該臂製作之材料或剖面。又，該補償臂被描述為旋轉者，但可由使用一沿縱向移動通過等於6、3、及12點鐘之位置的線性致動器或馬達而遵循一線性移動的一臂取代。 In addition, the arm 13 is rigid, however the arm may have its own minimum deflection to further cushion the compensation effect, such deflection being derived from the material or profile of the arm fabrication. Again, the compensating arm is described as a rotator, but can be replaced by an arm that follows a linear movement using a linear actuator or motor that moves longitudinally through positions equal to 6, 3, and 12 o'clock.

最後，已說明了存在有一與饋送器2之控制電子裝置共同作用的裝置1之控制單元。明顯地，該控制單元可為用於饋送器2者(即，該控制單元可為該控制電子裝置之一部份)，且當裝置1之本體11附接至饋送器2、自動地確認出存有裝置1時自動地作用(藉未顯示出之適當連接器偵測本體11存在，透過該等適當連接器，該控制單元將與裝置1之馬達、以及關聯於臂13之驅動軸的編碼器或位置感測器手段共同作用)。此解決方案顯示於第10C圖中。 Finally, it has been explained that there is a control unit of the device 1 that interacts with the control electronics of the feeder 2. Obviously, the control unit can be used for the feeder 2 (ie, the control unit can be part of the control electronics), and when the body 11 of the device 1 is attached to the feeder 2, it is automatically confirmed Automatically acts when the device 1 is stored (by the presence of a suitable connector that does not show the presence of the body 11 through which the control unit will encode the motor with the device 1 and the drive shaft associated with the arm 13 Or position sensor means work together). This solution is shown in Figure 10C.

本發明應用於饋送紡織紗線，但亦應用於饋送金屬線。 The invention is applied to feed textile yarns, but also to feed metal wires.
