本發明係有關繞線裝置、張力裝置及繞線方法。The invention relates to a winding device, a tension device and a winding method.
形成線圈之繞線裝置所具備之習知張力裝置，已知有檢測供給至繞線機之線材張力，根據此檢測值，控制送出線材之送出滾輪之轉數，以將線材張力保持於一定的裝置(參照日本特開平11－222357號公報、日本特開2000－128433號公報)。The conventional tension device provided in the winding device for forming a coil is known to detect the tension of the wire supplied to the winding machine, and according to the detected value, the number of rotations of the feeding roller for feeding the wire is controlled to maintain the wire tension constant. The device (refer to Japanese Laid-Open Patent Publication No. H11-222357, No. 2000-128433).
然而，於此種習知張力裝置中，在對剖面外徑不同的異徑繞線芯管、例如剖面形狀為長方形的繞線芯管，進行繞線的情況下，於繞線芯管旋轉一圈的時間內線材張力會周期性地變動。因此，會有送至繞線機之線材之張力難以保持一定的問題點存在。However, in such a conventional tension device, in the case where a different diameter winding core tube having a different outer diameter of the cross section, for example, a wound core tube having a rectangular cross section, is wound, the winding core tube is rotated. The wire tension changes periodically during the time of the circle. Therefore, there is a problem that it is difficult to maintain the tension of the wire supplied to the winding machine.
本發明係有鑑於上述問題點所為，其目的在於提供可抑制供給至繞線機之線材之張力變動的繞線裝置、張力裝置及繞線方法。The present invention has been made in view of the above problems, and an object thereof is to provide a winding device, a tension device, and a winding method capable of suppressing variation in tension of a wire supplied to a winding machine.
本發明為一種繞線裝置，係將線材捲繞於繞線芯管，其特徵在於，其具備：繞線芯管，係繞軸心旋轉，以捲繞線材；滾輪，係繞軸心旋轉，以對前述繞線芯管送出所捲掛之線材；以及張力裝置，係調節自前述滾輪供給至前述繞線芯管之線材的張力；捲掛於前述滾輪之線材的繞線形狀及繞線直徑，與捲繞於前述繞線芯管之線材的繞線形狀及繞線直徑大致相同。The present invention relates to a winding device for winding a wire around a wound core tube, characterized in that it comprises: a wound core tube which is rotated around an axis to wind the wire; and the roller rotates around the axis. And feeding the wire to be wound to the winding core tube; and tensioning device for adjusting tension of the wire supplied from the roller to the winding core tube; winding shape and winding diameter of the wire wound around the roller The winding shape and the winding diameter of the wire wound around the winding core tube are substantially the same.
利用本發明，由於即使在對剖面形狀直徑不同之繞線芯管進行繞線的情況下，捲掛於滾輪之線材的繞線形狀及繞線直徑與捲繞於繞線芯管之線材的繞線形狀及繞線直徑仍大致相同，因此，可抑制於繞線芯管旋轉一圈的時間內線材張力的變動。According to the present invention, the winding shape and the winding diameter of the wire wound around the roller and the winding of the wire wound around the winding core tube are wound even in the case where the winding core tube having different cross-sectional shape diameters is wound. Since the wire shape and the winding diameter are still substantially the same, it is possible to suppress the variation of the wire tension in one rotation of the winding core tube.
以下，參照圖式，說明本發明之實施形態。Hereinafter, embodiments of the present invention will be described with reference to the drawings.
參照圖1，說明本發明之第1實施形態的繞線裝置100。圖1係顯示繞線裝置100的立體圖。A winding device 100 according to a first embodiment of the present invention will be described with reference to Fig. 1 . FIG. 1 is a perspective view showing the winding device 100.
繞線裝置100係對繞軸心旋轉之繞線芯管(繞線管)11捲繞供自線材供給源2之線材3，藉此製造線圈的裝置。The winding device 100 is a device for winding a wire 3 supplied from a wire supply source 2 to a winding core tube (winding pipe) 11 that rotates around an axis.
繞線裝置100具備：繞線機10，係使繞線芯管11繞軸心旋轉驅動；線材送出機20，係對繞線芯管11供給供自線材供給源2的線材3；張力裝置15，係調節自線材送出機20供給至繞線機10之線材3的張力；以及控制器70，係控制繞線動作。The winding device 100 includes a winding machine 10 for rotationally driving the winding core tube 11 around the axis, and a wire feeding machine 20 for supplying the wire 3 supplied from the wire supply source 2 to the winding core tube 11; the tension device 15 The tension of the wire 3 supplied from the wire feeding machine 20 to the winding machine 10 is adjusted; and the controller 70 controls the winding operation.
繞線芯管11係由捲繞線材3的繞線胴部11a，以及設於繞線胴部11a之兩端面之用以限制線圈的捲繞寬度的突緣部11b所構成。The winding core tube 11 is composed of a winding weir portion 11a of the wound wire 3, and a flange portion 11b provided on both end faces of the winding weir portion 11a to restrict the winding width of the coil.
圖2A顯示繞線胴部11a中垂直於旋轉軸心的剖面。如圖2A所示，繞線胴部11a之剖面形狀中，自旋轉軸心O至外緣之尺寸之外徑a、b、c並非如圓為定值，而是形成為隨部位不同而異的異徑。本實施形態係顯示繞線胴部11a之剖面形狀為圖2A所示長方形的情形。Fig. 2A shows a section perpendicular to the axis of rotation in the winding weir portion 11a. As shown in FIG. 2A, in the cross-sectional shape of the winding weir portion 11a, the outer diameters a, b, and c of the size from the rotating axis O to the outer edge are not constant as a circle, but are formed to vary from part to site. Different diameter. In the present embodiment, the cross-sectional shape of the winding weir portion 11a is a rectangle as shown in Fig. 2A.
繞線機10具備：心軸12，係於一端部支持繞線芯管11；以及繞線馬達13，其輸出軸連結於心軸12的另一端。藉由繞線馬達13之旋轉驅動，使繞線芯管11繞軸心旋轉。The winding machine 10 includes a mandrel 12 that supports the winding core tube 11 at one end, and a winding motor 13 whose output shaft is coupled to the other end of the mandrel 12. The winding core tube 11 is rotated about the axis by the rotational driving of the winding motor 13.
繞線機10亦具備於旋轉軸方向輸送捲繞於繞線芯管11之線材3的導引機構(圖式省略)。藉由使用此導引機構進行繞線，可對繞線芯管11成排捲繞多層線材3。由於繞線芯管11之剖面形狀呈長方形，因此藉由將線材3捲繞於繞線芯管11，即可製造直角形線圈。The winding machine 10 also includes a guide mechanism (not shown) that conveys the wire 3 wound around the winding core tube 11 in the direction of the rotation axis. By winding the wire using this guiding mechanism, the multilayer wire 3 can be wound in a row in the winding core tube 11. Since the cross-sectional shape of the winding core tube 11 is rectangular, a rectangular angle coil can be manufactured by winding the wire 3 around the winding core tube 11.
線材送出機20具備：滾輪21，係捲掛自線材供給源2供給至繞線機10的線材3；以及送出馬達25，係旋轉驅動滾輪21。線材3繞一周捲掛於滾輪21，藉由送出馬達25旋轉驅動使滾輪21繞軸心旋轉，以對繞線芯管11送出捲掛於滾輪21的線材3。此外，繞線芯管11與滾輪21的旋轉軸形成為平行。The wire feeder 20 includes a roller 21 that winds up the wire 3 supplied from the wire supply source 2 to the winding machine 10, and a feed motor 25 that rotationally drives the roller 21. The wire 3 is wound around the roller 21 about one turn, and the roller 21 is rotated about the axis by the rotation of the feed motor 25 to feed the wire 3 wound around the roller 21 to the wound core tube 11. Further, the winding core tube 11 and the rotating shaft of the roller 21 are formed in parallel.
旋轉驅動繞線芯管11之繞線馬達13與旋轉驅動滾輪21之送出馬達25的旋轉速度，係藉控制器70之控制，於繞線中恆維持相同，且兩馬達13、25之旋轉相位於繞線中亦恆維持相同。The rotational speed of the winding motor 13 that rotationally drives the winding core tube 11 and the delivery motor 25 of the rotary driving roller 21 are maintained by the controller 70, and remain the same in the winding, and the rotating phases of the two motors 13, 25 It is also kept in the same way in the winding.
張力裝置15具備：滑輪16，係捲掛自滾輪21送出的線材；線速度變更馬達17，可旋轉驅動滑輪16並可變更滑輪16的旋轉速度；張力臂32，其基端部被支撐成可旋動；張力滑輪33，係設於張力臂32的旋動前端部，可供線材3捲掛；張力彈簧34，係往遠離繞線芯管11的方向彈壓張力臂32，以對線材3施加張力；以及編碼器35，係設於張力臂32之基端部，用來檢測張力臂32的旋動角度。The tension device 15 includes a pulley 16 that winds a wire that is fed from the roller 21, a linear speed changing motor that rotatably drives the pulley 16 and that changes the rotational speed of the pulley 16, and a tension arm 32 whose base end portion is supported to be supported. The tension pulley 33 is disposed at the rotating front end portion of the tension arm 32 for winding the wire 3; the tension spring 34 biases the tension arm 32 away from the winding core tube 11 to apply the wire 3 The tensioner and the encoder 35 are disposed at the base end of the tension arm 32 for detecting the angle of rotation of the tension arm 32.
張力臂32保持於可使線材3之張力與張力彈簧34之彈壓力平衡的旋動位置，若線材3之張力大於既定值，即抵抗張力彈簧34，朝接近繞線芯管11的方向(圖中下方)旋動，若線材3之張力小於既定值，即藉張力彈簧34之彈壓力，朝遠離繞線芯管11的方向(圖中上方)旋動。The tension arm 32 is held at a rotating position that can balance the tension of the wire 3 with the elastic pressure of the tension spring 34. If the tension of the wire 3 is greater than a predetermined value, that is, resist the tension spring 34, toward the winding core tube 11 (Fig. Middle and lower), if the tension of the wire 3 is less than a predetermined value, that is, by the elastic pressure of the tension spring 34, it is rotated away from the winding core tube 11 (upper in the figure).
張力彈簧34對張力臂32施加的彈壓力藉張力調整機構40調整。The spring pressure applied by the tension spring 34 to the tension arm 32 is adjusted by the tension adjusting mechanism 40.
張力調整機構40具備：滾珠螺桿42，係設於底座19；調整旋鈕43，係用來旋轉滾珠螺桿42；以及可動體41，係與滾珠螺桿42螺合而可沿滾珠螺桿42移動。張力彈簧34之一端部連結於張力臂32，另一端部連結於可動體41。The tension adjusting mechanism 40 includes a ball screw 42 that is attached to the base 19, an adjustment knob 43 that rotates the ball screw 42, and a movable body 41 that is screwed to the ball screw 42 to be movable along the ball screw 42. One end of the tension spring 34 is coupled to the tension arm 32, and the other end is coupled to the movable body 41.
張力彈簧34的張力，係透過旋轉調整旋鈕43旋轉滾珠螺桿42，藉此使可動體41升降來予以調整。此外，張力調整機構40對張力彈簧34所作張力調整係當作開始繞線前的初期設定來進行，於繞線中不進行。The tension of the tension spring 34 is rotated by the rotation adjustment knob 43 to adjust the tension of the movable body 41 by raising and lowering the ball screw 42. Further, the tension adjustment by the tension adjusting mechanism 40 to the tension spring 34 is performed as an initial setting before the start of winding, and is not performed in the winding.
張力臂32之旋動基端部連結於編碼器35的旋轉檢測軸31，編碼器35將對應張力臂32之旋轉角度的訊號輸出至控制器70。控制器70根據自編碼器35輸入的張力臂32的旋轉角度，計算線材3的張力，反饋控制線速度變更馬達17的旋轉速度，以使此算出之線材3的張力接近預先設定的既定值(目標值)。由於藉由控制線速度變更馬達17的旋轉速度，來變更自滑輪16送出的線材3的線速度，因此，線材3的張力被調節成目標值。The rotary base end portion of the tension arm 32 is coupled to the rotation detecting shaft 31 of the encoder 35, and the encoder 35 outputs a signal corresponding to the rotation angle of the tension arm 32 to the controller 70. The controller 70 calculates the tension of the wire 3 based on the rotation angle of the tension arm 32 input from the encoder 35, and feedbacks the control linear velocity to change the rotational speed of the motor 17, so that the calculated tension of the wire 3 approaches a predetermined value (a predetermined value ( Target value). Since the linear velocity of the wire 3 sent from the pulley 16 is changed by changing the rotational speed of the motor 17 by controlling the linear velocity, the tension of the wire 3 is adjusted to a target value.
於控制器70中收容有：CPU(中央處理單元)，係控制藉繞線裝置100所作之繞線動作；ROM(唯讀記憶體)，係儲存有CPU的處理動作所需映像等；RAM(隨機存取記憶體)，係暫時儲存自ROM讀出的資料或藉各儀表讀出的資料等。The controller 70 houses a CPU (Central Processing Unit) for controlling the winding operation by the winding device 100, and a ROM (read only memory) for storing images required for processing operations of the CPU; The random access memory) temporarily stores data read from the ROM or data read by each meter.
其次，說明線材送出機20中的滾輪21，以及用以調整捲掛於滾輪21之線材3之繞線直徑的機構。Next, the roller 21 in the wire feeder 20 and the mechanism for adjusting the diameter of the wire wound around the wire 3 of the roller 21 will be described.
另外，以下說明中，線材3之繞線形狀係指捲掛於繞線芯管11、滾輪21之線材3之環圈的形狀；又，線材3之繞線直徑係指環圈的內徑。In the following description, the winding shape of the wire 3 refers to the shape of the loop of the wire 3 wound around the winding core tube 11 and the roller 21; in addition, the winding diameter of the wire 3 refers to the inner diameter of the ring.
滾輪21的剖面形狀與繞線芯管11的剖面形狀相似，且形成剖面大小之輪徑沿旋轉軸方向連續變化的錐形。The cross-sectional shape of the roller 21 is similar to that of the winding core tube 11, and a tapered shape in which the wheel diameter of the cross-sectional shape continuously changes in the direction of the rotation axis is formed.
滾輪21供線材3捲掛之部位可藉由以滾輪徑調整機構50沿旋轉軸方向移動滾輪21來變更。具體而言，由於滾輪21形成為越向旋轉軸後方剖面積越大，因此，藉由向旋轉軸前方移動滾輪21，滾輪21供線材3捲掛之部位的輪徑變大，所捲掛之線材3的繞線直徑亦變大。The portion of the roller 21 on which the wire 3 is wound can be changed by moving the roller 21 in the direction of the rotation axis by the roller diameter adjusting mechanism 50. Specifically, since the roller 21 is formed to have a larger cross-sectional area toward the rear of the rotating shaft, by moving the roller 21 toward the front of the rotating shaft, the wheel diameter of the portion where the roller 21 is wound by the wire 3 is increased, and the roller is wound. The winding diameter of the wire 3 also becomes large.
又，由於滾輪21之剖面形狀與繞線芯管11之剖面形狀相似，因此，即使使滾輪21移動於旋轉軸方向，滾輪21供線材3捲掛之部位的剖面形狀仍與繞線芯管11的剖面形狀恆維持相同。Further, since the cross-sectional shape of the roller 21 is similar to the cross-sectional shape of the winding core tube 11, even if the roller 21 is moved in the direction of the rotation axis, the cross-sectional shape of the portion where the roller 21 is wound by the wire 3 is still the winding core tube 11 The profile shape remains the same.
藉由如上述沿旋轉軸方向移動滾輪21，可使捲掛於滾輪21之線材3的繞線形狀及繞線直徑與捲繞於繞線芯管11之線材3的繞線形狀及繞線直徑相同。By moving the roller 21 in the direction of the rotation axis as described above, the winding shape and the winding diameter of the wire 3 wound around the roller 21 and the winding shape and the winding diameter of the wire 3 wound around the winding core tube 11 can be made. the same.
滾輪徑調整機構50具備：馬達台52，係載置有送出馬達25；軌道53，係配置於底座19上，與送出馬達25的旋轉軸平行延伸；從動體51，係與馬達台52結合，可沿軌道53移動自如；滾珠螺桿54，係與從動體51螺合，與送出馬達25的旋轉軸平行延伸；以及滾輪移動馬達55，係旋轉驅動滾珠螺桿54。The roller diameter adjusting mechanism 50 includes a motor table 52 on which the delivery motor 25 is placed, and a rail 53 that is disposed on the base 19 and extends in parallel with the rotation shaft of the delivery motor 25, and the driven body 51 is coupled to the motor base 52. The ball screw 54 is slidably coupled to the driven body 51 and extends in parallel with the rotating shaft of the delivery motor 25; and the roller moving motor 55 rotationally drives the ball screw 54.
由於藉由驅動滾輪移動馬達55使馬達台52沿軌道53移動，因此，載置於馬達台52的送出馬達25即沿其旋轉軸方向移動。如此，即可藉由驅動滾輪移動馬達55，使滾輪21移動於旋轉軸方向，而由滾輪徑調整機構50變更滾輪21供線材3捲掛之部位之輪徑。Since the motor stage 52 is moved along the rail 53 by the drive roller moving motor 55, the delivery motor 25 placed on the motor stage 52 moves in the direction of its rotation axis. In this manner, the roller 21 can be moved in the direction of the rotation axis by the drive roller moving motor 55, and the wheel diameter adjustment mechanism 50 can change the wheel diameter of the portion where the roller 21 is wound by the wire 3.
又，滾輪徑調整機構50亦具備於滾輪21沿旋轉軸方向移動時，用來防止捲掛於滾輪21之線材3與滾輪21一起移動的導引機構(圖示省略)。由於藉由使用導引機構導引線材3通過既定路徑，因此，在滾輪21沿旋轉軸方向移動時，捲掛於滾輪21之線材3的繞線直徑亦隨之平穩變更。Further, the roller diameter adjusting mechanism 50 is also provided with a guide mechanism (not shown) for preventing the wire 3 wound around the roller 21 from moving together with the roller 21 when the roller 21 moves in the direction of the rotation axis. Since the guide wire guides the wire 3 through the predetermined path, the diameter of the wire wound around the wire 3 of the roller 21 is also smoothly changed as the roller 21 moves in the direction of the rotation axis.
於張力臂32之旋動前端部之張力滑輪33與繞線芯管11之間，設有檢測自滾輪21供給線材3至繞線芯管11之速度的速度檢測器60。A speed detector 60 for detecting the speed at which the wire 3 is supplied from the roller 21 to the winding core tube 11 is provided between the tension pulley 33 at the tip end portion of the swing arm 32 and the winding core tube 11.
速度檢測器60具備：滑輪61，係捲掛線材3；以及編碼器62，係檢測滑輪61的旋轉角度。將藉編碼器62檢測出之滑輪61的旋轉角度輸入控制器70，控制器70根據此輸入之旋轉角度，計算供給至繞線芯管11之線材3的速度。The speed detector 60 includes a pulley 61 that winds up the wire 3 and an encoder 62 that detects the rotation angle of the pulley 61. The rotation angle of the pulley 61 detected by the encoder 62 is input to the controller 70, and the controller 70 calculates the speed of the wire 3 supplied to the winding core tube 11 based on the rotation angle of the input.
此處，由於線材3累積捲繞於繞線芯管11之捲繞層數增加時，繞繞線芯管11一周之線材3長度會變長，因此，線材3的速度上昇。控制器70儲存有限定線材3之速度與捲繞層數間關係的第1映像，控制器70使用此映像，自所算出之線材3之速度判定線材3當下之捲繞層數，並根據此判定出之捲繞層數計算捲繞於繞線芯管11當下的繞線直徑。Here, since the number of winding layers in which the wire 3 is accumulated and wound around the winding core tube 11 is increased, the length of the wire 3 around the wire core tube 11 becomes long, and therefore the speed of the wire 3 rises. The controller 70 stores a first image defining the relationship between the speed of the wire 3 and the number of winding layers, and the controller 70 uses the image to determine the number of winding layers of the wire 3 from the calculated speed of the wire 3, and according to this The number of winding layers determined is determined as the diameter of the winding wound around the winding core tube 11.
控制器70另儲存有限定滾輪21朝旋轉軸方向之移動量與滾輪21供線材3捲掛之部位之輪徑之間關係的第2映像。此映像係根據滾輪21的錐度等來限定。控制器70使用此映像，控制滾輪21朝旋轉軸方向之移動量，以使滾輪21供線材3捲掛之部位的輪徑與所算出之繞線芯管11的繞線直徑相同。The controller 70 further stores a second image which defines the relationship between the amount of movement of the roller 21 in the direction of the rotation axis and the wheel diameter of the portion where the roller 21 is wound by the wire 3. This image is defined in accordance with the taper of the roller 21 or the like. Using this map, the controller 70 controls the amount of movement of the roller 21 in the direction of the rotation axis so that the wheel diameter of the portion where the roller 21 is wound by the wire 3 is the same as the diameter of the winding of the calculated winding core tube 11.
其次，說明藉控制器70控制之繞線裝置100的繞線動作。Next, the winding operation of the winding device 100 controlled by the controller 70 will be described.
自線材供給源2取出之線材3在捲掛於滾輪21一周後，捲掛於滑輪16、張力滑輪33及滑輪61，前端部藉機械手臂(圖示省略)繫於繞線芯管11的端子(圖示省略)上。The wire 3 taken out from the wire supply source 2 is wound around the roller 21, wound around the pulley 16, the tension pulley 33, and the pulley 61, and the distal end portion is attached to the terminal of the winding core tube 11 by a robot arm (not shown). (The illustration is omitted).
又，藉滾輪徑調整機構50調整滾輪21於旋轉軸方向之初期位置，以使滾輪21供線材3捲掛之部位的剖面大小與繞線芯管11之繞線胴部11a的剖面大小相同。Further, the roller diameter adjusting mechanism 50 adjusts the initial position of the roller 21 in the rotation axis direction so that the cross-sectional size of the portion where the roller 21 is wound by the wire 3 is the same as the cross-sectional size of the winding flange portion 11a of the winding core tube 11.
同步旋轉驅動繞線馬達13及送出馬達25，以使彼此旋轉速度相同，且彼此旋轉相位亦同。藉由如上述同步旋轉驅動繞線馬達13及送出馬達25，來將繞線芯管11與滾輪21的旋轉位置保持於相同位置。The winding motor 13 and the delivery motor 25 are synchronously rotated to rotate at the same speed and rotate in phase with each other. The winding position of the winding core tube 11 and the roller 21 is maintained at the same position by the synchronous rotation of the winding motor 13 and the delivery motor 25 as described above.
藉由旋轉驅動繞線馬達13及送出馬達25，將自滾輪21送出之線材3成排捲繞於繞線芯管11之繞線胴部11a外周。對繞線胴部11a之第1層繞線一結束，即於第1層線材3的外周進行第2層繞線，第2層繞線一結束，即於第2層線材3的外周進行第3層繞線。如上所述，於繞線胴部11a捲繞有多層線材3，每逢層數增加時，捲繞於繞線胴部11a之線材3的繞線直徑便增大。The wire 3 fed from the roller 21 is wound in a row around the outer circumference of the winding flange portion 11a of the winding core tube 11 by rotationally driving the winding motor 13 and the delivery motor 25. When the winding of the first layer of the winding portion 11a is completed, the second layer winding is performed on the outer circumference of the first layer wire 3, and the winding of the second layer is completed, that is, the outer circumference of the second layer wire 3 is performed. 3 layers of winding. As described above, the plurality of wires 3 are wound around the winding weir portion 11a, and the winding diameter of the wire 3 wound around the winding weir portion 11a increases as the number of layers increases.
藉控制器70運算線材3的繞線直徑。具體而言，根據速度檢測器60測得的線材3速度與上述第1映像判定當下的捲繞層數，並根據此判定出之捲繞層數運算當下捲繞於繞線芯管11的繞線直徑。The winding diameter of the wire 3 is calculated by the controller 70. Specifically, the speed of the wire 3 measured by the speed detector 60 and the number of winding layers of the current image are determined by the first image, and the winding of the winding core tube 11 is calculated based on the number of winding layers determined thereby. Line diameter.
然後，控制器70使用上述第2映像，控制滾輪21朝旋轉軸方向之前進移動量，以使每逢捲繞於繞線胴部11a之線材3的繞線直徑變大時，其繞線直徑與滾輪21供線材3捲掛之部位的輪徑相同。Then, the controller 70 controls the amount of movement of the roller 21 in the direction of the rotation axis by using the above-described second image so that the winding diameter is large every time the winding diameter of the wire 3 wound around the winding portion 11a becomes large. The wheel diameter of the portion where the roller 21 is wound by the wire 3 is the same.
由於滾輪21供線材3捲掛之部位的輪徑如上述變更成與捲繞於繞線胴部11a之線材3的繞線直徑相同，且滾輪21的剖面形狀與繞線芯管11的剖面形狀相似，因此，捲掛於滾輪21之線材3的繞線直徑及繞線形狀與捲繞於繞線胴部11a之線材3的繞線直徑及繞線形狀相同。The wheel diameter of the portion where the roller 21 is wound by the wire 3 is changed to be the same as the winding diameter of the wire 3 wound around the winding portion 11a, and the cross-sectional shape of the roller 21 and the sectional shape of the winding core tube 11 are changed. Similarly, the winding diameter and the winding shape of the wire 3 wound around the roller 21 are the same as the winding diameter and the winding shape of the wire 3 wound around the winding weir portion 11a.
如上述，於繞線中，捲掛於滾輪21之線材3的繞線直徑及繞線形狀被控制成與捲繞於繞線胴部11a之線材3的繞線直徑及繞線形狀相同，並且，同步控制繞線馬達13及送出馬達25之旋轉，以使彼此的旋轉速度相同，且彼此的旋轉相位相同。因此，即使於對剖面形狀為異徑之繞線芯管11捲繞線材3而線材3之速度有變化的情況下，自滾輪21送出之線材3的速度亦如同該速度變化而變化。因此，可抑制繞線芯管11與滾輪21間線材3之張力變動，而能控制張力臂32的擺動角度。As described above, in the winding, the winding diameter and the winding shape of the wire 3 wound around the roller 21 are controlled to be the same as the winding diameter and the winding shape of the wire 3 wound around the winding weir portion 11a, and The rotation of the winding motor 13 and the delivery motor 25 are synchronously controlled so that the rotational speeds of each other are the same and the rotational phases of each other are the same. Therefore, even when the wire 3 is wound around the wound core tube 11 having a different cross-sectional shape and the speed of the wire 3 is changed, the speed of the wire 3 fed from the roller 21 changes as the speed changes. Therefore, the tension fluctuation of the wire 3 between the winding core tube 11 and the roller 21 can be suppressed, and the swing angle of the tension arm 32 can be controlled.
參照圖2，進一步對此點詳加說明。圖2A係顯示繞線芯管11之剖面的剖面圖，圖2B係顯示線材3之速度變化情形的特性圖。Referring to Figure 2, this point will be further explained in detail. 2A is a cross-sectional view showing a cross section of the wound core tube 11, and FIG. 2B is a characteristic diagram showing a change in speed of the wire 3.
如圖2A所示，於剖面呈長方形之繞線芯管11的剖面中，自旋轉中心O至長邊11A的長度為a，自旋轉中心O至短邊11B的長度為b，自旋轉中心O至角部11C的距離為c。此時，於繞線芯管11的旋轉角速度保持為定值ω之情況下，如圖2B所示，捲繞於繞線芯管11之線材3之速度(縱軸)以相對於繞線芯管11之旋轉角度(橫軸)產生a ω、c ω、b ω、c ω、a ω、…之反曲點的方式變動。As shown in FIG. 2A, in the cross section of the winding core tube 11 having a rectangular cross section, the length from the center of rotation O to the long side 11A is a, and the length from the center of rotation O to the length of the short side 11B is b, and the center of rotation O The distance to the corner portion 11C is c. At this time, in the case where the rotational angular velocity of the winding core tube 11 is maintained at a constant value ω, as shown in FIG. 2B, the speed (vertical axis) of the wire 3 wound around the winding core tube 11 is relative to the winding core. The rotation angle (horizontal axis) of the tube 11 varies in a manner in which the inflection points of a ω , c ω , b ω , c ω , a ω , .
此處，由於在滾輪21的剖面形狀如習知呈圓形的情況下，對繞線芯管11捲繞線材3，張力臂32會周期性擺動，因此，須對應圖2B所示線材3之速度，控制線速度變更馬達17的旋轉角速度。因此，難以將供給至繞線芯管11之線材3的張力控制成恒定，若使用較細線材3，有因張力變動而導致線材3斷裂的可能性。Here, since the wire member 3 is wound around the winding core tube 11 in the case where the cross-sectional shape of the roller 21 is circular as is conventionally known, the tension arm 32 periodically oscillates, and therefore, it is necessary to correspond to the wire 3 shown in FIG. 2B. The speed and the control linear velocity change the rotational angular velocity of the motor 17. Therefore, it is difficult to control the tension of the wire 3 supplied to the winding core tube 11 to be constant, and if the thinner wire 3 is used, there is a possibility that the wire 3 is broken due to the tension fluctuation.
相對於此，由於本實施形態係將捲掛於滾輪21之線材3的繞線直徑及繞線形狀控制成與捲繞於繞線胴部11a之線材3的繞線直徑及繞線形狀相同，因此，藉由將滾輪21之旋轉角速度保持於與繞線芯管11為相同定值ω，可使自滾輪21送出之線材3的速度，亦如圖2B所示變化成與捲繞於繞線芯管11之線材3的速度相同。因此，可抑制繞線芯管11與滾輪21間線材3的張力變動，而能抑制張力臂32的周期性擺動。藉此，可精度極佳地將供給至繞線芯管11之線材3的張力保持於恒定，而能製造高品質的線圈。On the other hand, in the present embodiment, the winding diameter and the winding shape of the wire 3 wound around the roller 21 are controlled to be the same as the winding diameter and the winding shape of the wire 3 wound around the winding portion 11a. Therefore, by maintaining the rotational angular velocity of the roller 21 at the same constant value ω as that of the winding core tube 11, the speed of the wire 3 fed from the roller 21 can be changed to be wound around the winding as shown in Fig. 2B. The speed of the wire 3 of the core tube 11 is the same. Therefore, the tension fluctuation of the wire 3 between the winding core tube 11 and the roller 21 can be suppressed, and the periodic swing of the tension arm 32 can be suppressed. Thereby, the tension of the wire 3 supplied to the winding core tube 11 can be kept constant with high precision, and a high-quality coil can be manufactured.
另外，雖然繞線芯管11與滾輪21間線材3之張力變動可藉由如上述變更滾輪21供線材3捲掛之部位的輪徑來控制，但有時會因滾輪徑變更的控制滯後等，以致於繞線芯管11與滾輪21間線材3之張力暫時變動，造成張力臂32擺動。於此情況下，藉由線速度變更馬達17動作，變更自滑輪16送出之線材3的線速度，將線材3的張力控制(調節)於目標值。線速度變更馬達17如上述動作，以補足藉滾輪徑調整機構50所為之輪徑變更控制。Further, although the tension variation of the wire 3 between the winding core tube 11 and the roller 21 can be controlled by changing the wheel diameter of the portion where the wire 21 is wound by the roller 21 as described above, the control lag of the change of the roller diameter may be caused. Therefore, the tension of the wire 3 between the winding core tube 11 and the roller 21 temporarily changes, causing the tension arm 32 to swing. In this case, the linear velocity changing motor 17 operates to change the linear velocity of the wire 3 sent from the pulley 16, and the tension of the wire 3 is controlled (adjusted) to the target value. The linear speed change motor 17 is operated as described above to complement the wheel diameter change control by the roller diameter adjustment mechanism 50.
於期望層數之繞線結束後，以機械手臂切斷線材3，將線材3之終端部繫於繞線芯管11的端子上(圖示省略)。然後，自心軸12卸下繞線芯管11，安裝新的繞線芯管11於心軸12。如上述流程製造線圈。After the winding of the desired number of layers is completed, the wire 3 is cut by a robot arm, and the end portion of the wire 3 is attached to the terminal of the winding core tube 11 (not shown). Then, the winding core tube 11 is detached from the mandrel 12, and a new winding core tube 11 is attached to the mandrel 12. The coil was fabricated as described above.
另外，本實施形態雖然將滾輪21形成為塊體狀，但本發明不限於此，亦可將滾輪21形成為捲掛線材3之框狀，藉致動器變更框之大小。亦即，為了使捲掛線材3之繞線形狀及繞線直徑符合期望，使滾輪21供線材3捲掛之部位的形狀及大小為可變亦可。Further, in the present embodiment, the roller 21 is formed in a block shape, but the present invention is not limited thereto, and the roller 21 may be formed in a frame shape of the winding wire 3, and the size of the frame may be changed by the actuator. That is, in order to make the winding shape and the winding diameter of the wound wire 3 desirable, the shape and size of the portion where the roller 21 is wound by the wire 3 may be changed.
根據以上所示本實施形態，可發揮以下所示效果。According to the embodiment described above, the following effects can be exhibited.
即使於對剖面形狀為異徑之繞線芯管11捲繞線材3的情況下，仍可將捲掛於滾輪21之線材3的繞線形狀及繞線直徑控制成與捲繞於繞線芯管11之線材3的繞線形狀及繞線直徑相同。因此，可精度極佳地控制捲繞於繞線芯管11之線材3的張力，而能抑制張力變動。藉此，提高所製造之不同直徑線圈的品質。Even in the case where the wire 3 is wound around the wound core tube 11 having a different cross-sectional shape, the winding shape and the winding diameter of the wire 3 wound around the roller 21 can be controlled to be wound around the winding core. The wire shape of the wire 3 of the tube 11 and the winding diameter are the same. Therefore, the tension of the wire 3 wound around the winding core tube 11 can be excellently controlled with high precision, and the tension variation can be suppressed. Thereby, the quality of the coils of different diameters manufactured is improved.
又，滾輪21與繞線芯管11剖面形狀相似，且形成為輪徑沿旋轉軸方向連續變化的錐形。因此，滾輪21供線材3捲掛之部位的輪徑，可藉由滾輪徑調整機構50沿旋轉軸方向移動滾輪21而變更為理想直徑，且即使沿旋轉軸方向移動滾輪21，滾輪21供線材3捲掛之部位之剖面形狀仍與繞線芯管11的剖面形狀恆維持相同。藉由如上述使滾輪21之形狀與繞線芯管11之剖面形狀相似，並沿旋轉軸方向形成為錐形，只要沿旋轉軸方向移動滾輪21，即可使捲掛於滾輪21之線材3的繞線形狀及繞線直徑與捲繞於繞線芯管11之線材3的繞線形狀及繞線直徑相同。Further, the roller 21 is similar in cross-sectional shape to the winding core tube 11, and is formed in a tapered shape in which the wheel diameter continuously changes in the direction of the rotation axis. Therefore, the wheel diameter of the portion where the roller 21 is wound by the wire 3 can be changed to a desired diameter by moving the roller 21 in the direction of the rotation axis by the roller diameter adjusting mechanism 50, and the roller 21 is supplied with the wire even if the roller 21 is moved in the direction of the rotation axis. The cross-sectional shape of the portion where the coil is wound is still maintained the same as the cross-sectional shape of the wound core tube 11. By making the shape of the roller 21 similar to the cross-sectional shape of the winding core tube 11 as described above and forming a taper in the direction of the rotation axis, as long as the roller 21 is moved in the direction of the rotation axis, the wire 3 wound around the roller 21 can be wound. The winding shape and the winding diameter are the same as the winding shape and the winding diameter of the wire 3 wound around the winding core tube 11.
參照圖3，說明本發明第2實施形態的繞線裝置200。圖3係顯示繞線裝置200的立體圖。A winding device 200 according to a second embodiment of the present invention will be described with reference to Fig. 3 . FIG. 3 is a perspective view showing the winding device 200.
以相同符號標示本實施形態之繞線裝置200與上述第1實施形態之繞線裝置100相同的構成，並省略說明。以下，以和繞線裝置100之相異點為中心加以說明。The winding device 200 of the present embodiment has the same configuration as that of the winding device 100 of the first embodiment, and the description thereof is omitted. Hereinafter, a description will be given focusing on the difference from the winding device 100.
繞線裝置200與上述第1實施形態之繞線裝置100的相異點在於，張力裝置15的構成有部分不同。The winding device 200 is different from the winding device 100 of the above-described first embodiment in that the configuration of the tension device 15 is partially different.
上述第1實施形態之繞線裝置100中之張力裝置15，係藉由控制線速度變更馬達17之旋轉速度來變更自滑輪16送出之線材3的線速度，以調節自滾輪21供給至繞線芯管11之線材3的張力。In the tension device 15 of the winding device 100 according to the first embodiment, the linear velocity of the wire 3 sent from the pulley 16 is changed by controlling the rotational speed of the linear speed changing motor 17, so as to adjust the supply from the roller 21 to the winding. The tension of the wire 3 of the core tube 11.
相對於此，繞線裝置200之張力裝置150並未具備滑輪16及線速度變更馬達17，而係以改變送出馬達25的旋轉速度來調節自滾輪21供給至繞線芯管11之線材3的張力。On the other hand, the tension device 150 of the winding device 200 does not include the pulley 16 and the linear velocity changing motor 17, but adjusts the rotational speed of the delivery motor 25 to adjust the wire 3 supplied from the roller 21 to the winding core tube 11. tension.
繞線裝置200之繞線芯管11與滾輪21間線材3的張力變動，如同第1實施形態，係藉由變更滾輪21供線材3捲掛之部位的輪徑來抑制。然而，當因滾輪徑變更的控制滯後等使繞線芯管11與滾輪21間線材3之張力變動，而造成張力臂32擺動時，則藉由送出馬達25動作，控制(調節)線材3的張力。如上所述，繞線裝置200係以送出馬達25之動作來補足滾輪徑調整機構50之輪徑變更控制。The tension variation of the wire 3 between the winding core tube 11 and the roller 21 of the winding device 200 is suppressed by changing the wheel diameter of the portion where the roller 21 is wound by the wire member 3 as in the first embodiment. However, when the tension of the wire 3 between the winding core tube 11 and the roller 21 is varied due to the control lag of the change in the diameter of the roller, and the tension arm 32 is swung, the wire 3 is controlled (adjusted) by the operation of the delivery motor 25. tension. As described above, the winding device 200 complements the wheel diameter changing control of the roller diameter adjusting mechanism 50 by the operation of the feeding motor 25.
當送出馬達25為補足滾輪徑變更控制而動作時，送出馬達25與繞線馬達13之旋轉相位會因送出馬達25的旋轉速度增減而不一致。然而，此相位不一致係暫態，只要滾輪徑調整機構50之輪徑變更控制穩定，送出馬達25與繞線馬達13的旋轉速度及旋轉相位便會再度相同。When the delivery motor 25 is operated to compensate for the roller diameter change control, the rotational phase of the delivery motor 25 and the winding motor 13 does not coincide with the increase or decrease in the rotational speed of the delivery motor 25. However, this phase is inconsistent with the transient state, and as long as the wheel diameter change control of the roller diameter adjusting mechanism 50 is stabilized, the rotational speed and the rotational phase of the delivery motor 25 and the winding motor 13 are again the same.
根據以上所示本實施形態，可發揮以下所示效果。According to the embodiment described above, the following effects can be exhibited.
不必設置特別設備來調節繞線芯管11與滾輪21間之線材3的張力，可藉簡便構造，獲得與上述第1實施形態相同的作用效果。It is not necessary to provide a special device to adjust the tension of the wire 3 between the winding core tube 11 and the roller 21, and the same operational effects as those of the above-described first embodiment can be obtained by a simple structure.
又，若考慮將滾輪徑調整機構50應用於藉由改變送出馬達25之旋轉速度來控制自滾輪21供給至繞線芯管11之線材3之張力，即使在對剖面異徑之繞線芯管11進行繞線的情況下，仍可利用滾輪徑調整機構50之輪徑變更控制來抑制送出馬達25之旋轉速度變化，精度極佳地控制捲繞於繞線芯管11之線材3的張力。Further, it is considered that the roller diameter adjusting mechanism 50 is applied to control the tension of the wire 3 supplied from the roller 21 to the winding core tube 11 by changing the rotational speed of the delivery motor 25, even in the winding core tube of the cross-section different diameter. When the winding is performed, the rotation speed change of the delivery motor 25 can be suppressed by the wheel diameter change control of the roller diameter adjustment mechanism 50, and the tension of the wire 3 wound around the winding core tube 11 can be excellently controlled with high precision.
本發明不限於上述實施形態，可在其技術思想範圍內做各種變更。The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the technical idea.
