線鋸及引線進行之工件之切斷方法 Wire saw and wire cutting method for workpiece

本發明係關於一種使移行之引線擠壓於工件而切斷該工件的線鋸、及引線進行之工件之切斷方法。 The present invention relates to a wire saw for cutting a workpiece by pressing a traveling lead, and a method of cutting the workpiece by the lead.

JP1999-291154A中揭示有如下線鋸:使利用電鍍或樹脂將鑽石等研磨粒固定於芯線上而成的固定研磨粒引線移行,使引線接觸於工件,從而切斷工件。JP1999-291154A所揭示之線鋸中,使自引線供給部送出之引線由引線回收部收捲,且使於其間移動之引線接觸於工件而將該工件切斷。 JP1999-291154A discloses a wire saw in which a fixed abrasive grain lead obtained by fixing abrasive grains such as diamond to a core wire by electroplating or resin is moved, and the lead wire is brought into contact with the workpiece to cut the workpiece. In the wire saw disclosed in JP 1999-291154 A, the lead wire fed from the lead supply portion is wound by the wire collecting portion, and the lead wire moved therebetween is brought into contact with the workpiece to cut the workpiece.

就此種線鋸而言,於引線供給部與引線回收部之間移動的一根引線係以繞掛於複數個多槽輥之間且排列成並排狀、且向相同方向移行的方式受到牽引。藉由將工件擠壓於由如此受到牽引的引線所形成之複數個切斷部,可將工件同時切斷加工成複數個薄片。 In such a wire saw, one lead wire that moves between the lead supply portion and the lead wire collecting portion is wound so as to be wound around a plurality of multi-groove rollers and arranged in a row and in the same direction. The workpiece can be simultaneously cut into a plurality of sheets by pressing the workpiece against a plurality of cut portions formed by the lead thus drawn.

於此種線鋸中,為了高效率地切斷工件,須將構成切斷部之引線的張力維持於適當的範圍。當引線過度緊繃時,引線會產生斷線。因此,JP1999-291154A揭示之線鋸中,另具備有輥,該輥壓接於引線供給部之供給側捲盤與於引線回收部之回收側捲盤。該線鋸中,驅動供給側及收捲(回收)側之兩壓接輥,從而間接地驅動供給側捲盤與回收側捲盤。藉此,JP1999-291154A揭示之線鋸中,使供給側捲盤與回收側捲盤之間非同步地產 生的張力變化於壓接輥上滑動,藉此將其吸收,從而實現引線之張力穩定化。 In such a wire saw, in order to cut the workpiece efficiently, the tension of the lead wires constituting the cut portion must be maintained within an appropriate range. When the lead is too tight, the lead will break. Therefore, the wire saw disclosed in JP1999-291154A is further provided with a roller which is crimped to the supply side reel of the lead supply portion and the recovery side reel of the lead take-up portion. In the wire saw, two pressure rollers on the supply side and the winding (recycling) side are driven to indirectly drive the supply side reel and the recovery side reel. Therefore, in the wire saw disclosed in JP1999-291154A, the asynchronous land between the supply side reel and the recovery side reel is made. The tension of the raw material is changed by sliding on the pressure roller, thereby absorbing it, thereby stabilizing the tension of the wire.

然而,若以使用複數個多槽輥將一根引線排列成並排狀、且向相同方向移行的方式進行牽引而形成切斷部、且將工件擠壓於切斷部之引線,則自引線供給部送出後接觸於工件的引線會因其阻力而使之後的張力產生變動。因此,難以令使一根引線呈並排狀牽引而形成且同時切斷工件之複數個切斷部的所有張力變得均一。 However, when a plurality of multi-groove rolls are arranged in a side-by-side manner and pulled in the same direction to form a cut portion, and the workpiece is pressed against the lead of the cut portion, the lead wire is supplied. After the portion is fed out, the lead wire that contacts the workpiece changes its subsequent tension due to its resistance. Therefore, it is difficult to make all the tensions of the plurality of cut portions formed by pulling one lead in a side-by-side manner and simultaneously cutting the workpiece to be uniform.

本發明之目的在於提供一種能使牽引一根引線而形成的切斷工件之複數個切斷部的張力獲得均一的線鋸、及引線進行之工件之切斷方法。 SUMMARY OF THE INVENTION An object of the present invention is to provide a wire saw with a plurality of cut portions for cutting a workpiece formed by pulling one lead, and a method for cutting a workpiece by a lead.

以下,參照隨附圖式對於本發明之實施形態進行說明。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

圖1中表示本發明之實施形態之線鋸10的構成。線鋸10具有:引線供給部,其送出引線11;引線回收部,其將送出的引線11回收;及切斷部,其形成於引線供給部與引線回收部之間。切斷部係藉由引線供給部與引線回收部之間的移動途中的引線11形成,且以切斷工件12的方式構成。 Fig. 1 shows the configuration of a wire saw 10 according to an embodiment of the present invention. The wire saw 10 has a lead supply portion that feeds the lead wires 11 , a lead wire collecting portion that collects the supplied lead wires 11 , and a cut portion that is formed between the lead wire supply portion and the lead wire collecting portion. The cutting portion is formed by the lead wire 11 in the middle of the movement between the lead supply portion and the lead wire collecting portion, and is configured to cut the workpiece 12.

圖2~圖4中表示線鋸10的具體構成。線鋸10具備:引線送出裝置20,其構成引線供給部;引線回收裝置120,其構成引線回收部;及加工機本體40,其將自引線送出裝置20送出後由引線回收裝置120回收的移動途中的引線11牽引至內部。以下,於各圖中,設定彼此正交的X、Y及Z該等3軸,使X軸於略水平前後方向延伸,使Y軸於略水平橫方向延伸,使Z軸於鉛垂方向延伸,從而對線鋸10的構成進行說明。 The specific configuration of the wire saw 10 is shown in Figs. 2 to 4 . The wire saw 10 includes a lead wire feeding device 20 that constitutes a wire supply portion, a wire collecting device 120 that constitutes a wire collecting portion, and a processing machine body 40 that is transported from the wire feeding device 20 and then recovered by the wire collecting device 120. The lead 11 on the way is pulled to the inside. Hereinafter, in each of the drawings, three axes of X, Y, and Z orthogonal to each other are set, the X axis is extended in the horizontal horizontal direction, the Y axis is extended in the horizontal direction, and the Z axis is extended in the vertical direction. Thus, the configuration of the wire saw 10 will be described.

引線送出裝置20、加工機本體40及引線回收裝置120係依序沿Y軸方向並排而設。引線送出裝置20與引線回收裝置120形成為對稱構造,且其各構成相同。引線送出裝置20與引線回收裝置120分別向正轉方向與反轉方向做動。 The lead wire feeding device 20, the processing machine main body 40, and the lead wire collecting device 120 are sequentially arranged in the Y-axis direction. The lead wire feeding device 20 and the lead wire collecting device 120 are formed in a symmetrical structure, and their respective configurations are the same. The lead wire feeding device 20 and the lead wire collecting device 120 are respectively moved in the normal rotation direction and the reverse rotation direction.

若引線送出裝置20送出引線、且引線回收裝置120回收引線的情況視為正轉方向,則當為反轉方向時,引線回收裝置120作為送出裝置(引線供給部)發揮功能,引線送出裝置20作為引線回收裝置(引線回收部)發揮功能。此時,僅引線11之送出與回收的運行相反,故而,本實施形態中,以正轉方向上的引線送出裝置20為中心進行說明。而且,引線回收裝置120之捲盤122~旋轉馬達134分別與引線送出裝置20之捲盤22~旋轉馬達34為同樣地構成,故而,省略其詳細說明。而且,於正轉方 向上的說明中,如後述之送出側絞盤31、回收側絞盤131般,因應需要使用「送出側」、「回收側」等表達,以下,將圖1所示之箭頭方向作為正轉方向進行說明。 When the lead wire feeding device 20 feeds the lead wire and the lead wire collecting device 120 collects the lead wire as the forward rotation direction, the lead wire collecting device 120 functions as a feeding device (lead supply portion) when the wire is fed in the reverse direction, and the wire feeding device 20 It functions as a lead collection device (lead collection unit). At this time, only the lead wire 11 is sent out in the opposite direction to the recovery operation. Therefore, in the present embodiment, the lead wire feeding device 20 in the normal rotation direction will be mainly described. Further, since the reel 122 to the rotary motor 134 of the lead wire collecting device 120 are configured similarly to the reel 22 to the rotary motor 34 of the lead wire feeding device 20, detailed description thereof will be omitted. Moreover, in the positive turn In the above description, as described above, the delivery side winch 31 and the recovery side winch 131 are required to use the expressions such as "sending side" and "recovery side". Hereinafter, the direction of the arrow shown in FIG. 1 will be described as the forward direction. .

如圖2~圖4所示,引線送出裝置20具備台板21,該台板21具有複數個安裝腳21a。台板21係以可透過伸長的複數個安裝腳21a而水平地設置的方式構成。台板21上,設有旋轉軸沿X軸方向延伸的捲盤22(參照圖2)。捲盤22係將引線11捲繞於其捲體部而儲線。捲盤22係以其旋轉軸可旋轉的方式設於支撐台23。支撐台23係以於可旋轉地支撐捲盤22的狀態下可沿捲盤22的軸向(X軸方向)移動的方式安裝於台板21。 As shown in FIGS. 2 to 4, the lead wire feeding device 20 is provided with a platen 21 having a plurality of mounting legs 21a. The platen 21 is configured to be horizontally provided by a plurality of elongated mounting legs 21a. The platen 21 is provided with a reel 22 (see Fig. 2) in which the rotating shaft extends in the X-axis direction. The reel 22 winds the lead wire 11 around the winding body portion thereof to store the wire. The reel 22 is provided on the support table 23 so that its rotation axis is rotatable. The support base 23 is attached to the platen 21 so as to be movable in the axial direction (X-axis direction) of the reel 22 in a state where the reel 22 is rotatably supported.

此處,捲繞於捲盤22之引線11係用作線鋸10的切斷齒,且本實施形態中由所謂固定研磨粒引線而構成。固定研磨粒引線係利用電鍍或樹脂而將鑽石等研磨粒固定於芯線即引線的周圍而成者。引線11並不限於固定研磨粒引線,只要能切斷工件12,則亦可為其他類型的引線。 Here, the lead 11 wound around the reel 22 is used as a cutting tooth of the jigsaw 10, and in the present embodiment, it is constituted by a so-called fixed abrasive grain lead. The fixed abrasive grain lead is obtained by fixing abrasive grains such as diamond to the periphery of the lead wire, such as a lead, by plating or resin. The lead 11 is not limited to the fixed abrasive grain lead, and other types of leads may be used as long as the workpiece 12 can be cut.

雖未圖示,但於支撐台23設有使捲盤22旋轉的送出馬達。送出馬達為能使引線供給用之捲盤22的旋轉速度變更的伺服馬達。於送出馬達,連接有未圖示的控制器的控制輸出線。而且,送出馬達基於來自控制器的指令而使引線供給用之捲盤22按規定的速度旋轉,藉此,可自捲盤22送出引線11。 Although not shown, a feeding motor that rotates the reel 22 is provided on the support base 23. The delivery motor is a servo motor that can change the rotational speed of the reel 22 for lead supply. A control output line of a controller (not shown) is connected to the delivery motor. Further, the delivery motor rotates the reel 22 for supplying the lead at a predetermined speed based on an instruction from the controller, whereby the lead 11 can be fed from the reel 22.

於台板21的上表面,組裝有箱體24(參照圖3)。於捲盤22上方之箱體24的前表面,安裝有與X軸正交且平行於YZ平面的鉛垂板25。如圖2所示,於鉛垂板25上設有位置檢測機構26,該位置檢測機構26係對於自於X軸方向(捲盤22的軸向)捲盤22送出之引線11的位置進行 檢測。 A casing 24 is assembled on the upper surface of the platen 21 (see Fig. 3). On the front surface of the casing 24 above the reel 22, a vertical plate 25 orthogonal to the X-axis and parallel to the YZ plane is mounted. As shown in FIG. 2, a position detecting mechanism 26 is provided on the vertical plate 25, and the position detecting mechanism 26 performs the position of the lead wire 11 fed from the reel 22 from the X-axis direction (the axial direction of the reel 22).

如圖1所示,設於殼體41(參照圖2)內的第1及第2負載單元51、52係對於切斷工件12前後的前側引線11a的張力進行檢測者。第3及第4負載單元53、54係對於切斷工件12前後的後側引線11b的張力進行檢測者。第1~第4負載單元51~54之檢測輸出線連接於未圖示的控制 器。 As shown in FIG. 1, the first and second load cells 51 and 52 provided in the casing 41 (see FIG. 2) detect the tension of the front lead 11a before and after the workpiece 12 is cut. The third and fourth load cells 53 and 54 detect the tension of the rear lead 11b before and after the workpiece 12 is cut. The detection output lines of the first to fourth load units 51 to 54 are connected to a control not shown Device.

控制器係基於第1及第2負載單元51、52之檢測輸出而控制前側旋轉馬達34,從而控制送出側絞盤31的旋轉。藉此,控制器對於在送出側絞盤31與傳送絞盤46之間移動的前側引線11a的張力進行調整。 The controller controls the front side rotation motor 34 based on the detection outputs of the first and second load units 51 and 52 to control the rotation of the delivery side winch 31. Thereby, the controller adjusts the tension of the front side lead 11a that moves between the delivery side winch 31 and the transfer winch 46.

而且,控制器係基於第3及第4負載單元53、54之檢測輸出而控制後側旋轉馬達134,從而控制回收側絞盤131的旋轉。藉此,控制器對於在傳送絞盤46與回收側絞盤131之間移動的後側引線11b的張力進行調整。 Further, the controller controls the rear side rotation motor 134 based on the detection outputs of the third and fourth load units 53, 54 to control the rotation of the recovery side winch 131. Thereby, the controller adjusts the tension of the rear side lead 11b that moves between the transfer winch 46 and the recovery side winch 131.

若利用傳送絞盤46使1根引線11以固定的速度移動、且利用傳送絞盤46前後的引線11切斷工件12,則先切斷工件12之前側引線11a的切斷加工時產生的阻力會施加於之後切斷工件12的後側引線11b。因此,進行切斷加工的前側引線11a與後側引線11b的張力有產生相異之虞。 When one lead 11 is moved at a fixed speed by the transfer winch 46, and the workpiece 12 is cut by the lead 11 before and after the transfer winch 46, the resistance generated when the cutting of the front side lead 11a of the workpiece 12 is first cut is applied. The rear side lead 11b of the workpiece 12 is then cut. Therefore, the tension between the front side lead 11a and the rear side lead 11b which are subjected to the cutting process differs.

對此,本實施形態中,控制送出側絞盤31的旋轉而對前側引線11a的張力進行調整,且控制回收側絞盤131的旋轉而對後側引線11b的張力進行調整。因此,能分別調整前側引線11a與後側引線11b的張力。藉此,能使同時切斷工件12之前側引線11a與後側引線11b的張力變得均一,從而能更穩定地對工件12進行切削加工。 On the other hand, in the present embodiment, the rotation of the feed-side winch 31 is controlled to adjust the tension of the front lead 11a, and the rotation of the recovery-side winch 131 is controlled to adjust the tension of the rear lead 11b. Therefore, the tension of the front side lead 11a and the rear side lead 11b can be adjusted separately. Thereby, the tension between the front side lead 11a and the rear side lead 11b of the workpiece 12 can be made uniform at the same time, and the workpiece 12 can be more stably cut.

第1、第2負載單元51、52係對於切斷工件12前後的前側引線11a的張力進行檢測,第3、第4負載單元53、54係對於切斷工件12前後的後側引線11b的張力進行檢測。因此,藉由以第1、第3負載單元51、53的值變得相等、且第2、第4負載單元52、54的值亦變得相等的方式,對於前側引線11a及後側引線11b的張力進行調整,能更確實地進行均一化 的切斷加工。此處,利用傳送絞盤46而使引線11的移動速度固定,故而,引線11之移動速度不會隨著張力調整而變化。 The first and second load cells 51 and 52 detect the tension of the front lead 11a before and after the workpiece 12 is cut, and the third and fourth load units 53 and 54 are the tension of the rear lead 11b before and after the workpiece 12 is cut. Test. Therefore, the front lead wire 11a and the rear side lead wire 11b are the same as the values of the first and third load cells 51 and 53 are equal, and the values of the second and fourth load cells 52 and 54 are also equal. The tension is adjusted to make it more uniform Cutting process. Here, since the moving speed of the lead wire 11 is fixed by the transfer winch 46, the moving speed of the lead wire 11 does not change with the tension adjustment.

若藉由傳送絞盤46的旋轉而使引線11移動,則藉由送出側絞盤31的旋轉而自引線送出裝置20的捲盤22送出引線11。若自送出側之捲盤22的送出量相對於引線11之移動量而有所增加,則繞掛於張力裝置27之一對導輥27a、27b的引線11的全長會增加。因此,鬆緊調節臂27c向圖2中實線箭頭所示的左方向旋轉。 When the lead wire 11 is moved by the rotation of the transfer winch 46, the lead wire 11 is fed out from the reel 22 of the lead wire feeding device 20 by the rotation of the feed side winch 31. When the amount of the reel 22 fed from the delivery side increases with respect to the amount of movement of the lead 11, the total length of the lead 11 wound around the pair of guide rolls 27a and 27b of the tension device 27 increases. Therefore, the dancer arm 27c is rotated in the left direction indicated by the solid arrow in FIG.

反之,若引線11自送出側之捲盤22的送出量減少,則繞掛於一對導輥27a、27b的引線11的全長會減少。因此,鬆緊調節臂27c向圖2中虛線箭頭所示的右方向旋轉。 On the other hand, when the amount of the lead wire 11 fed from the take-up side of the reel 22 is reduced, the total length of the lead wire 11 wound around the pair of guide rolls 27a and 27b is reduced. Therefore, the dancer arm 27c is rotated in the right direction indicated by the dotted arrow in FIG.

鬆緊調節臂27c自中立位置起的旋轉可由未圖示的編碼器而檢測。控制器係基於編碼器之檢測輸出而對於使送出側的捲盤22旋轉的未圖示的馬達進行控制,且變更調整捲盤22的旋轉速度而將引線11的送出量調整為與傳送絞盤46的移動量相同。藉此,鬆緊調節臂27c維持於中立位置。 The rotation of the dancer arm 27c from the neutral position can be detected by an encoder (not shown). The controller controls a motor (not shown) that rotates the reel 22 on the delivery side based on the detection output of the encoder, and changes the rotation speed of the adjustment reel 22 to adjust the delivery amount of the lead 11 to the transfer winch 46. The amount of movement is the same. Thereby, the elastic adjustment arm 27c is maintained at the neutral position.

於引線回收裝置120中,藉由使回收側絞盤131旋轉而回收引線11,從而將其捲繞於回收側的捲盤122。若回收側的捲盤122的回收量減少,則繞掛於張力裝置127之一對導輥127a、127b的引線11的全長會增加。因此,鬆緊調節臂127c向圖2中實線箭頭所示的右方向旋轉。 In the lead collection device 120, the lead wire 11 is recovered by rotating the recovery-side winch 131, and is wound around the reel 122 on the recovery side. When the amount of recovery of the reel 122 on the recovery side is reduced, the total length of the lead 11 wound around the pair of guide rolls 127a and 127b of the tension device 127 is increased. Therefore, the dancer arm 127c is rotated in the right direction indicated by the solid arrow in FIG.

反之,若回收側的捲盤122的回收量增加,則繞掛於一對導輥127a、127b的引線11的全長亦減少。因此,鬆緊調節臂127c向圖2中虛線箭頭所示的左方向旋轉。 On the other hand, when the amount of recovery of the reel 122 on the recovery side is increased, the total length of the lead 11 wound around the pair of guide rolls 127a and 127b is also reduced. Therefore, the dancer arm 127c is rotated in the left direction indicated by the dotted arrow in FIG.

鬆緊調節臂127c自中立位置起的旋轉可由未圖示的編碼器而檢測。控制器係基於編碼器之檢測輸出而對於使回收側的捲盤122旋轉的馬達進行控制,且變更調整回收側的捲盤122的旋轉速度,從而將引線11的回收量調整為與傳送絞盤46所致的引線11的移動量相同。藉此,鬆緊調節臂127c維持於中立位置。 The rotation of the dancer arm 127c from the neutral position can be detected by an encoder (not shown). The controller controls the motor that rotates the reel 122 on the recovery side based on the detection output of the encoder, and changes the rotation speed of the reel 122 on the recovery side to adjust the amount of recovery of the lead 11 to the transfer winch 46. The resulting amount of movement of the lead wires 11 is the same. Thereby, the dancer arm 127c is maintained at the neutral position.

於拉入引線送出裝置20與引線回收裝置120之間的引線11的加工機本體40中,藉由傳送絞盤46的旋轉,使得被牽引至殼體41內部的引線11的移動速度始終固定。而且,於殼體41的內部,利用複數個滑輪43而繞掛前側引線11a與後側引線11b。圖6中表示滑輪43、及使該滑輪43之全部或一部分移動的制動器44。具體而言,於殼體41內部的工件12的上方設有頂板41d(參照圖2),於頂板41d設有制動器44。 In the processing machine body 40 that pulls the lead 11 between the lead feeding device 20 and the lead collecting device 120, the moving speed of the lead 11 pulled into the inside of the casing 41 is always fixed by the rotation of the conveying winch 46. Further, inside the casing 41, the front side lead 11a and the rear side lead 11b are wound by a plurality of pulleys 43. In Fig. 6, a pulley 43 and a brake 44 for moving all or part of the pulley 43 are shown. Specifically, a top plate 41d (see FIG. 2) is provided above the workpiece 12 inside the casing 41, and a stopper 44 is provided on the top plate 41d.

圖6中表示前側引線11a被牽引至X軸方向上的靠近門41b、41c(參照圖2)的近前側、後側引線11b被牽引至其裡側的情況。於殼體41的內部設有4根撐桿56~59,於該等4根撐桿56~59,上下樞支有對引線11進行牽引的滑輪43。具體而言,於X軸方向上的門41b、41c側,設有於Y軸方向上並排的第1及第2撐桿56、57該等2根撐桿。樞支於第1及第2撐桿56、57的滑輪43對前側引線11a進行牽引。 Fig. 6 shows a case where the front lead 11a is pulled to the near side of the doors 41b and 41c (see Fig. 2) in the X-axis direction, and the rear lead 11b is pulled to the inside. Four struts 56 to 59 are provided inside the casing 41, and the pulleys 43 for pulling the lead wires 11 are vertically supported by the four struts 56 to 59. Specifically, on the side of the doors 41b and 41c in the X-axis direction, the first and second stays 56 and 57 which are arranged side by side in the Y-axis direction are provided with two struts. The pulley 43 pivotally supported by the first and second stays 56 and 57 pulls the front lead 11a.

於遠離門41b、41c之側,設有於Y軸方向上並排的第3及第4撐桿58、59之之2根撐桿。樞支於第3及第4撐桿58、59的滑輪43對後側引線11b進行牽引。 On the side away from the doors 41b and 41c, two struts of the third and fourth stays 58 and 59 which are arranged side by side in the Y-axis direction are provided. The pulley 43 pivotally supported by the third and fourth stays 58, 59 pulls the rear lead 11b.

制動器44係透過第1、第2、第3、第4撐桿56、57、58、59之4根撐桿而使複數個滑輪43以可移動的方式構成。第1撐桿56不可 移動地固定於頂板41d。 The brake 44 is configured to movably form a plurality of pulleys 43 through the four struts of the first, second, third, and fourth struts 56, 57, 58, and 59. The first pole 56 is not available It is movably fixed to the top plate 41d.

另一方面,第2撐桿57係藉由制動器44而於Y軸方向及Z軸方向雙方以可移動的方式構成。繞掛在樞支於第1及第2撐桿56、57的滑輪43且切斷工件12的前側引線11a係,可藉由改變第1及第2撐桿56、57間的Y軸方向上的距離而變更全長。而且,切斷工件12的前側引線11a係藉由使第2撐桿57於Z軸方向上升降而可傾斜於水平方向之構成。 On the other hand, the second stay 57 is movably configured by the brake 44 in both the Y-axis direction and the Z-axis direction. The front lead 11a of the workpiece 12 is wound around the pulley 43 pivotally supported by the first and second stays 56, 57, and the Y-axis direction between the first and second stays 56, 57 can be changed. The total length is changed by the distance. Further, the front lead wire 11a that cuts the workpiece 12 is configured to be inclined in the horizontal direction by raising and lowering the second stay 57 in the Z-axis direction.

制動器44係使第3撐桿58於X軸方向以可移動的方式構成。第4撐桿59係於3軸方向中的任一方向以可移動的方式構成。 The brake 44 is configured to movably move the third stay 58 in the X-axis direction. The fourth stay 59 is movably configured in any of the three axial directions.

因此,繞掛在樞支於第3、第4撐桿58、59的滑輪43且切斷工件12的後側引線11b係,可藉由變更第3、第4撐桿58、59間的Y軸方向上的距離而變更全長。而且,切斷工件12的後側引線11b係藉由使第3、第4撐桿58、59中的任一者於Z軸方向上升降,而可傾斜於水平方向之構成。 Therefore, by winding the pulleys 43 pivotally supported by the third and fourth stays 58, 59 and cutting the rear lead 11b of the workpiece 12, the Y between the third and fourth stays 58 and 59 can be changed. The total length is changed by the distance in the axial direction. Further, the rear side lead 11b that cuts the workpiece 12 can be inclined in the horizontal direction by raising and lowering any of the third and fourth stays 58 and 59 in the Z-axis direction.

若使第3、第4撐桿58、59沿X軸方向移動而變更第1、第2撐桿56、57之間的X軸方向上的距離,則可變更前側引線11a與後側引線11b的距離。 When the third and fourth stays 58 and 59 are moved in the X-axis direction to change the distance in the X-axis direction between the first and second stays 56 and 57, the front lead 11a and the rear lead 11b can be changed. the distance.

繼而,對於本實施形態之引線進行之工件之切斷方法進行說明。 Next, a method of cutting the workpiece by the lead wire of the present embodiment will be described.

於本實施形態之引線進行之工件之切斷方法中,如圖1所示,係利用作為引線供給部之引線送出裝置20送出、且由作為引線回收部之引線回收裝置120收捲的引線11切斷工件12之方法;該切斷方法中,於將引線送出裝置20與引線回收裝置120之間的引線11繞掛於傳送絞盤46 的狀態下,使傳送絞盤46旋轉,藉此使引線11移動,且利用送出側絞盤31,對於較傳送絞盤46更靠前側(引線送出裝置20側)的前側引線11a的張力進行調整,利用回收側絞盤131,對於較傳送絞盤46更靠後側(引線回收裝置120側)的後側引線11b的張力進行調整,利用於張力已調整的狀態下在送出側絞盤31與傳送絞盤46之間移動的前側引線11a、及於張力已調整的狀態下在傳送絞盤46與回收側絞盤131之間移動的後側引線11b,切斷工件12。 In the method of cutting the workpiece by the lead wire of the present embodiment, as shown in FIG. 1, the lead wire 11 which is fed by the lead wire feeding device 20 as the wire supply portion and wound by the wire collecting device 120 as the lead wire collecting portion is taken up. a method of cutting the workpiece 12; in the cutting method, the lead 11 between the lead feeding device 20 and the lead collecting device 120 is wound around the conveying winch 46 In the state in which the transfer winch 46 is rotated, the lead wire 11 is moved, and the tension of the front lead wire 11a on the front side (the lead wire feeding device 20 side) of the transfer winch 46 is adjusted by the feed side winch 31. The recovery side winch 131 adjusts the tension of the rear side lead 11b on the rear side (the lead recovery device 120 side) of the transfer winch 46, and is used between the delivery side winch 31 and the transfer winch 46 in a state where the tension is adjusted. The moving front side lead 11a and the rear side lead 11b which is moved between the transfer winch 46 and the recovery side winch 131 in a state where the tension is adjusted are cut off the workpiece 12.

於使用圖2~圖4所示的線鋸10時,首先,打開設於殼體41的前表面的門41b、41c而將切斷對象物即工件12搭載於升降機42的搭載台42a(圖2)。並且,將自引線送出裝置20送出的引線11牽引至殼體41的內部且繞掛於傳送絞盤46。 When the wire saw 10 shown in FIG. 2 to FIG. 4 is used, first, the doors 41b and 41c provided on the front surface of the casing 41 are opened, and the workpiece 12, which is the object to be cut, is mounted on the mounting table 42a of the elevator 42 (Fig. 2). Further, the lead wire 11 fed from the lead wire feeding device 20 is pulled to the inside of the casing 41 and wound around the conveying winch 46.

之後,利用引線回收裝置120,將被拉出至殼體41外部的引線11回收。此時,傳送絞盤46露出於殼體41的外部而設,故而,對於引線11進行牽引等配索作業相對容易,且之後的切斷加工作業途中的保養檢查亦容易。 Thereafter, the lead wire 11 pulled out to the outside of the casing 41 is recovered by the wire collecting device 120. At this time, since the transfer winch 46 is exposed to the outside of the casing 41, it is relatively easy to perform the work of pulling the lead wire 11 and the like, and the maintenance inspection in the middle of the cutting work is easy.

而且,如圖6所示,利用制動器44使設於殼體41內部而對引線11進行牽引的複數個滑輪43移動,將實際切斷工件12的前側引線11a及後側引線11b調整至所需的長度或位置。 Further, as shown in FIG. 6, a plurality of pulleys 43 provided inside the casing 41 and pulling the lead wires 11 are moved by the brakes 44, and the front side lead wires 11a and the rear side lead wires 11b which actually cut the workpiece 12 are adjusted to the required state. Length or position.

如圖2所示,於此狀態下使傳送絞盤46以固定的速度旋轉,且使繞掛於其上的引線11始終以相同的速度移動。藉此,設於引線送出裝置20中的送出側絞盤31亦旋轉,自引線送出裝置20的捲盤22依序地送出引線11。另一方面,於引線回收裝置120中,回收側絞盤131旋轉,引線 11捲繞於回收側的捲盤122而得以回收。 As shown in Fig. 2, in this state, the transfer winch 46 is rotated at a fixed speed, and the lead wires 11 wound thereon are always moved at the same speed. Thereby, the delivery side winch 31 provided in the lead wire feeding device 20 also rotates, and the lead wires 11 are sequentially fed out from the reel 22 of the lead wire feeding device 20. On the other hand, in the lead recovery device 120, the recovery side winch 131 is rotated, and the lead is turned The reel 11 is wound around the recovery side to be recovered.

若使傳送絞盤46旋轉,則被牽引至殼體41內部的前側引線11a及後側引線11b分別於長度方向上移動,故而,於此狀態下,升降機42使工件12與搭載台42a一同上升。而且,使工件12接觸於在長度方向上移動的前側引線11a及後側引線11b雙方。之後,亦藉由使工件12,而利用引線11切斷工件12。 When the transport winch 46 is rotated, the front lead 11a and the rear lead 11b pulled into the inside of the casing 41 are respectively moved in the longitudinal direction. Therefore, in this state, the lift 42 raises the workpiece 12 together with the mounting base 42a. Further, the workpiece 12 is brought into contact with both the front lead 11a and the rear lead 11b which are moved in the longitudinal direction. Thereafter, the workpiece 12 is also cut by the lead wires 11 by the workpiece 12.

當切斷工件12時,利用送出側絞盤31對於切斷工件12的前側引線11a的張力進行調整,且利用回收側絞盤131對於與前側引線11a一同切斷工件12的後側引線11b的張力進行調整。 When the workpiece 12 is cut, the tension of the front side lead 11a of the workpiece 12 is adjusted by the delivery side winch 31, and the tension of the rear side lead 11b of the workpiece 12 is cut together with the front side lead 11a by the recovery side winch 131. Adjustment.

利用於張力已調整的狀態下在送出側絞盤31與傳送絞盤46之間移動的前側引線11a、及於張力已調整的狀態下在傳送絞盤46與回收側絞盤131之間移動的後側引線11b,切斷工件12。 The front side lead 11a that moves between the delivery side winch 31 and the transfer winch 46 in a state where the tension is adjusted, and the rear side lead 11b that moves between the transfer winch 46 and the recovery side winch 131 in a state where the tension is adjusted , the workpiece 12 is cut.

此處,實際切斷工件12的前側引線11a與後側引線11b係由1根引線11構成。因此,先切斷工件12的前側引線11a的切斷加工時產生的阻力會施加於之後切斷工件12的後側引線11b,從而,進行切斷加工的前側引線11a與後側引線11b的張力有相異之虞。 Here, the front lead 11a and the rear lead 11b which actually cut the workpiece 12 are constituted by one lead 11. Therefore, the resistance generated when the cutting process of the front side lead 11a of the workpiece 12 is first cut is applied to the rear side lead 11b of the workpiece 12, and the tension of the front side lead 11a and the rear side lead 11b which are cut. There are differences.

對此,於本實施形態之引線進行之工件之切斷方法中,以傳送絞盤46的旋轉為基準,而控制送出側絞盤31的旋轉,從而對位於傳送絞盤46之前的前側引線11a的張力進行調整。而且,控制回收側絞盤131的旋轉,而對位於傳送絞盤46之後的後側引線11b的張力進行調整。藉此,能分別調整前側引線11a與後側引線11b的張力,且能使同時切斷工件12的前側引線11a與後側引線11b的張力變得均一。因此,能更穩定地對工件 12進行切削加工。 On the other hand, in the method of cutting the workpiece by the lead wire according to the present embodiment, the rotation of the feed-side winch 31 is controlled based on the rotation of the transfer winch 46, and the tension of the front lead 11a before the transfer winch 46 is performed. Adjustment. Moreover, the rotation of the recovery side winch 131 is controlled, and the tension of the rear side lead 11b located after the transfer winch 46 is adjusted. Thereby, the tension of the front side lead 11a and the rear side lead 11b can be adjusted separately, and the tension of the front side lead 11a and the rear side lead 11b which cut the workpiece 12 simultaneously can be made uniform. Therefore, the workpiece can be more stably 12 for cutting.

圖2~圖5中所示的本實施形態的線鋸10中,在殼體41的內部,利用複數個滑輪43對引線11進行牽引。由此,線鋸10與習知的線鋸不同,先前的線鋸係以使一根引線11於複數個多槽輥間呈並排狀向相同方向移行的方式進行牽引。 In the wire saw 10 of the present embodiment shown in FIGS. 2 to 5, the lead wires 11 are pulled by a plurality of pulleys 43 inside the casing 41. Thus, the wire saw 10 is different from the conventional wire saw in that a wire saw 11 is pulled in such a manner that one lead 11 travels in the same direction side by side between a plurality of multi-groove rolls.

而且,本實施形態之線鋸10進而具備使複數個滑輪43的一部分或全部移動的制動器44,故而,能自由地調整前側引線11a及後側引線11b的長度或位置、及其角度。因此,即便被切斷對象物即工件12的大小不同時,亦能按照所需的位置或形狀而對大小或形狀不同的工件12進行切斷。 Further, the wire saw 10 of the present embodiment further includes the brake 44 that moves a part or all of the plurality of pulleys 43, so that the length or position of the front lead 11a and the rear lead 11b and the angle thereof can be freely adjusted. Therefore, even when the size of the workpiece 12, which is the object to be cut, is different, the workpiece 12 having a different size or shape can be cut in accordance with the desired position or shape.

本實施形態中,已對於自引線送出裝置20送出的引線11經過傳送絞盤46而由引線回收裝置120回收的正轉方向上的動作進行了說明。 In the present embodiment, the operation in the forward rotation direction of the lead wire 11 sent from the lead feeding device 20 through the transfer winch 46 and recovered by the lead collecting device 120 has been described.

此時,自引線送出裝置20送出的引線11全部由引線回收裝置120回收之後,只要進行將引線回收裝置120設為「送出側」、經過傳送絞盤46而將引線送出裝置20設為「回收側」的反轉方向的動作即可。藉由如此進行動作,能反復進行正轉方向與反轉方向的動作。藉此,可使用至磨損引線11為止,且能於已使張力均一的狀態下穩定地進行切削加工。進而,能提高切削加工的作業性及生產性。 In this case, after the lead wires 11 sent from the lead wire feeding device 20 are all collected by the wire collecting device 120, the wire collecting device 20 is set as the "feeding side", and the wire feeding device 20 is set as the "recycling side". The action in the reverse direction can be. By performing the operation as described above, the operations in the forward rotation direction and the reverse rotation direction can be repeated. Thereby, it is possible to use the wear lead 11 and to perform the cutting process stably in a state where the tension is uniform. Further, workability and productivity of the cutting process can be improved.

根據以上的實施形態,可發揮以下所示的作用效果。 According to the above embodiment, the following effects can be exhibited.

本實施形態之線鋸10具備:引線送出裝置20,其送出引線11;引線回收裝置120,其將送出的引線11回收;複數個切斷部,其藉由對引線送出裝置20與引線回收裝置120之間的引線11進行牽引而形成,且 切斷工件12;傳送絞盤46,其於繞掛有引線送出裝置20與引線回收裝置120之間的引線11的狀態下旋轉,藉此使引線11移動;送出側絞盤31,其設在引線送出裝置20中,且於繞掛有較之傳送絞盤46更靠引線送出裝置20側的前側引線11a的狀態下旋轉,藉此,調整前側引線11a的張力;及回收側絞盤131,其設在引線回收裝置120中,且於繞掛有較之傳送絞盤46更靠引線回收裝置120側的後側引線11b的狀態下旋轉,藉此,調整後側引線11b的張力;且,複數個切斷部係由在送出側絞盤31與傳送絞盤46之間移動的前側引線11a、及在傳送絞盤46與回收側絞盤131之間移動的後側引線11b形成。 The wire saw 10 of the present embodiment includes a lead wire feeding device 20 that feeds the lead wires 11 , a lead wire collecting device 120 that collects the supplied lead wires 11 , and a plurality of cutting portions that pass the lead wire feeding device 20 and the wire lead collecting device The lead 11 between 120 is formed by pulling, and The workpiece 12 is cut; the winch 46 is rotated, and the lead 11 is wound around the lead 11 between the lead feeding device 20 and the lead collecting device 120, thereby moving the lead 11; the sending side winch 31 is set to be fed out. In the apparatus 20, the front side lead 11a on the side of the lead feeding device 20 is rotated in comparison with the transfer winch 46, thereby adjusting the tension of the front side lead 11a; and the recovery side winch 131 is provided on the lead The recovery device 120 rotates in a state in which the rear lead 11b on the side of the lead collection device 120 is wound with respect to the transfer winch 46, thereby adjusting the tension of the rear lead 11b; and a plurality of cut portions It is formed by a front side lead 11a that moves between the delivery side winch 31 and the transfer winch 46, and a rear side lead 11b that moves between the transfer winch 46 and the recovery side winch 131.

而且,本實施形態之引線11進行之工件12之切斷方法中,藉由使自引線送出裝置20與引線回收裝置120之間的引線11繞掛於傳送絞盤46而使傳送絞盤46旋轉,從而使引線11移動,且利用送出側絞盤31對於較傳送絞盤46更靠引線送出裝置20側的前側引線11a的張力進行調整,利用回收側絞盤131對於較之傳送絞盤46更靠引線回收裝置120側的後側引線11b的張力進行調整,且利用於張力已調整的狀態下在送出側絞盤31與傳送絞盤46之間移動的前側引線11a、及於張力已調整的狀態下在傳送絞盤46與回收側絞盤131之間移動的後側引線11b,切斷工件12。 Further, in the method of cutting the workpiece 12 by the lead 11 of the present embodiment, the lead wire 11 between the lead feeding device 20 and the lead collecting device 120 is wound around the transfer winch 46 to rotate the transfer winch 46, thereby The lead 11 is moved, and the tension of the front side lead 11a on the side of the lead feeding device 20 is adjusted by the delivery side winch 31. The recovery side winch 131 is further connected to the lead recovery device 120 side than the transfer winch 46. The tension of the rear side lead 11b is adjusted, and the front side lead 11a that moves between the delivery side winch 31 and the transfer winch 46 in a state where the tension is adjusted is used, and the transfer winch 46 and the recovery are performed in a state where the tension is adjusted. The rear side lead 11b, which is moved between the side winches 131, cuts the workpiece 12.

若將1根引線回折而成為2根引線、且利用該2根引線切斷工件,則先切斷工件的前側引線的切斷加工時產生的阻力會施加於之後切斷工件的後側引線,從而,進行切斷加工的前引線與後引線的張力有相異之虞。本實施形態之線鋸及引線進行之工件之切斷方法中,亦利用傳送絞盤46使1根引線11移動。 When one lead is folded back to form two leads, and the workpiece is cut by the two leads, the resistance generated during the cutting process of the front lead of the workpiece is first applied to the rear lead after the workpiece is cut. Therefore, the tension between the front lead and the rear lead which are subjected to the cutting process is different. In the wire saw and the method of cutting the workpiece by the lead wire of the present embodiment, the one lead wire 11 is also moved by the transfer winch 46.

然而,本實施形態中,控制送出側絞盤31的旋轉而調整前側引線11a的張力,且控制回收側絞盤131的旋轉而調整後側引線11b的張力。因此,能分別調整前側引線11a與後側引線11b的張力。藉此,能使同時切斷工件12的前側引線11a與後側引線11b的張力變得均一,且能更穩定地對工件12進行切削加工。 In the present embodiment, the rotation of the feed side winch 31 is controlled to adjust the tension of the front lead 11a, and the rotation of the recovery side winch 131 is controlled to adjust the tension of the rear lead 11b. Therefore, the tension of the front side lead 11a and the rear side lead 11b can be adjusted separately. Thereby, the tension of the front side lead 11a and the rear side lead 11b which cut the workpiece 12 at the same time can be made uniform, and the workpiece 12 can be cut more stably.
