Description

本発明は、線材の外表面に形成された皮膜を剥離する皮膜剥離装置及び皮膜剥離方法に関するものである。   The present invention relates to a film peeling apparatus and a film peeling method for peeling a film formed on the outer surface of a wire.

従来、絶縁皮膜等の皮膜に被覆された線材を用いて巻線を行う場合には、線材を絡げる端子との電気的接触を確保するために、又は直接電気的接触部とするために線材の皮膜を部分的に剥離する必要がある。そして、断面形状が長方形である平角線材の絶縁皮膜を剥離する装置として、回転するローラやすりを絶縁皮膜に当接させて、その絶縁皮膜を剥離する装置が知られている。このような装置の場合、ローラやすり又は線材を移動させることによって絶縁皮膜の剥離を行うけれども、最初にローラやすりを平角線材に押し付ける部分、つまり剥離部の端部に窪みができてしまう不具合がある。   Conventionally, when winding is performed using a wire covered with a film such as an insulating film, in order to ensure electrical contact with a terminal that ties the wire, or to make a direct electrical contact portion It is necessary to partially peel the wire film. As a device for peeling off an insulating film of a rectangular wire having a rectangular cross-sectional shape, an apparatus that peels the insulating film by bringing a rotating roller file into contact with the insulating film is known. In the case of such an apparatus, although the insulating film is peeled off by moving the roller file or the wire, there is a problem that a depression is first formed at the portion where the roller file is pressed against the flat wire, that is, at the end of the peeling portion. .

このような不具合を解消するために、本出願人は、断面が方形を成す線材の対向する主面に切削具を当接させて主面に形成された皮膜に切込みを加え、その皮膜に切込みを加えた切削具を線材に対して線材長手方向に相対移動させることによって皮膜を剥離する皮膜剥離装置を提案した(例えば、特許文献1参照。)。この皮膜剥離装置は、切削具を線材に対して相対的に移動させるだけで皮膜を除去することができ、ローラやすりを用いた剥離装置のように、平角線材に窪みができるような事態を回避することができるものである。   In order to solve such a problem, the present applicant adds a cut to the coating formed on the main surface by bringing a cutting tool into contact with the opposing main surface of the wire having a square cross section, and cutting into the coating. The film peeling apparatus which peels a film | membrane by moving relative to the wire rod longitudinal direction with respect to the wire rod was proposed (for example, refer patent document 1). This film peeling device can remove the film just by moving the cutting tool relative to the wire, avoiding the situation where the flat wire is dent like the peeling device using roller files. Is something that can be done.

しかし、断面が方形を成す線材にあっては、互いに対向する両主面にのみならず、その主面に直交して互いに対向する両側面にも皮膜が形成される。また、主面と側面が交差する角部が断面において湾曲しているようなものであれば、その湾曲する角部においても皮膜が形成される。そして、上記皮膜剥離装置では、その切削具は断面が方形を成す線材の対向する主面における皮膜に切込みを加えるものであるので、その切削具を線材に対して線材長手方向に相対移動させることによって剥離される皮膜はその主面のものとなり、その主面に直交する側面における皮膜は残存することになる。側面における皮膜は残存していたとしても、線材の対向する主面の皮膜が剥離されれば、その線材と端子との電気的接触は確保することができるけれども、上記皮膜剥離装置ではその線材の全周に形成された皮膜を剥離することはできずに、その線材の全周に形成された皮膜の剥離が要求された場合に、その要求に対応することができないという未だ解決すべき課題が残存していた。   However, in a wire having a square cross section, a film is formed not only on both main surfaces facing each other but also on both side surfaces orthogonal to the main surface and facing each other. Further, if the corner where the main surface and the side surface intersect is curved in the cross section, a film is also formed at the curved corner. And in the said film peeling apparatus, since the cutting tool adds a cut | disconnection to the film | membrane in the main surface which the cross-section forms a square wire, the cutting tool is moved relatively to a wire longitudinal direction with respect to a wire. As a result, the film peeled off becomes the main surface, and the film on the side surface orthogonal to the main surface remains. Even if the film on the side surface remains, if the film on the opposing main surface of the wire is peeled off, electrical contact between the wire and the terminal can be ensured. When the film formed on the entire circumference cannot be peeled off and the film formed on the entire circumference of the wire is required to be peeled off, there is still a problem to be solved that the request cannot be met. It remained.

本発明の目的は、線材の全周における皮膜を容易に剥離し得る線材の皮膜剥離装置及びその皮膜剥離方法を提供することにある。   The objective of this invention is providing the film peeling apparatus of the wire which can peel the film | membrane in the perimeter of a wire easily, and its film peeling method.

本発明における線材の皮膜剥離装置は、線材を支持する線材支持手段と、線材を挟むように対向して設けられた一対の切削具と、一対の切削具を線材の外表面に形成された皮膜に線材の両側から当接させて皮膜に切込みを加える切込み付与手段と、皮膜に切込みを加えた一対の切削具を線材に対して長手方向に相対移動させて皮膜を剥離する切削具相対移動手段とを備えた皮膜剥離装置の改良である。   A wire film peeling apparatus according to the present invention includes a wire material supporting means for supporting a wire material, a pair of cutting tools provided to face each other so as to sandwich the wire material, and a film in which the pair of cutting tools are formed on the outer surface of the wire material Cutting means for making a cut in the film by abutting from both sides of the wire, and a cutting tool relative moving means for separating the film by moving a pair of cutting tools in which the film has been cut relative to the wire in the longitudinal direction It is improvement of the film peeling apparatus provided with.

その特徴ある構成は、線材を挟むように対向して設けられた一対の切削具を線材を回転中心として回転させる切削具回転手段が設けられたところにある。   The characteristic configuration is that a cutting tool rotating means is provided for rotating a pair of cutting tools provided facing each other so as to sandwich the wire.

そして、切削具回転手段は線材が貫通しかつ線材を回転中心として回転可能に設けられた回転部材を有し、その回転部材に一対の切削具を設けることが好ましい。   And it is preferable that the cutting tool rotating means has a rotating member provided so that the wire passes therethrough and is rotatable around the wire, and the rotating member is provided with a pair of cutting tools.

本発明における線材の皮膜剥離方法は、線材を挟むように対向して設けられた一対の切削具を線材の外表面に形成された皮膜に線材の両側から当接させてその皮膜に切込みを加え、皮膜に切込みを加えた一対の切削具を線材に対して線材長手方向に相対移動させることによって皮膜を剥離する皮膜剥離工程と、外面から一対の切削具を離間させて皮膜剥離工程において一対の切削具が皮膜に切込みを加えた位置まで一対の切削具を戻す切削具戻し工程とを順次繰り返す皮膜剥離方法である。   In the wire film peeling method according to the present invention, a pair of cutting tools provided facing each other so as to sandwich the wire are brought into contact with the film formed on the outer surface of the wire from both sides of the wire, and the film is cut. A pair of cutting tools in which a cut is added to the film, and a pair of cutting tools for separating the film by moving the pair of cutting tools relative to the wire in the longitudinal direction of the wire; This is a film peeling method that sequentially repeats a cutting tool returning step of returning a pair of cutting tools to a position at which the cutting tool cuts the film.

その特徴ある点は、切削具戻し工程において線材を回転中心として線材を挟むように対向して設けられた一対の切削具を回転させるところにある。   The characteristic point is that in the cutting tool returning step, a pair of cutting tools provided facing each other so as to sandwich the wire with the wire as the rotation center is rotated.

そして、線材を回転中心として線材が貫通しかつ一対の切削具が設けられた回転部材を回転させることにより、線材を回転中心として一対の切削具を回転させることが好ましい。   And it is preferable to rotate a pair of cutting tool centering on a wire rod by rotating the rotating member which a wire rod penetrated and made a pair of cutting tool centering on a wire rod.

本発明では、例えば、皮膜を剥離しようとする線材が平角線材であったとしても、その平角線材の対向する主面に一対の切削具を当接させて切込みを加え、その後その一対の切削具を線材に対して長手方向に移動させることによって、線材の対向する両主面における皮膜をそれぞれ剥離することができる。そして、本発明の線材の皮膜剥離装置及びその皮膜剥離方法では、線材を回転中心として一対の切削具を回転させるので、対向する両主面における皮膜をそれぞれ剥離した後、最初に皮膜に切込みを加えた位置まで一対の切削具を戻すとともに、線材を回転中心としてその一対の切削具を回転させて、例えば、その線材の両側面に対向させるようにすれば、その平角線材の対向する両側面に一対の切削具を当接させて切込みを加え、その後その一対の切削具を再び線材に対して長手方向に移動させることによって、線材の対向する両側面における皮膜をそれぞれ剥離することができる。   In the present invention, for example, even if the wire to be peeled off is a flat wire, a pair of cutting tools are brought into contact with the opposing principal surfaces of the flat wire, and then the pair of cutting tools are applied. Is moved in the longitudinal direction with respect to the wire, so that the coatings on both main surfaces of the wire facing each other can be peeled off. In the wire film peeling apparatus and the film peeling method of the present invention, the pair of cutting tools are rotated about the wire as the rotation center. Therefore, after peeling the films on the opposing main surfaces, respectively, the film is first cut. When the pair of cutting tools are returned to the added position and the pair of cutting tools are rotated around the wire rod as a rotation center so as to face both side surfaces of the wire rod, for example, the opposite side surfaces of the flat wire rod A pair of cutting tools are brought into contact with each other to make incisions, and then the pair of cutting tools are moved in the longitudinal direction again with respect to the wire, whereby the films on the opposite side surfaces of the wire can be peeled off.

即ち、本発明の線材の皮膜剥離装置及びその皮膜剥離方法では、線材を回転中心として一対の切削具を回転させて、線材の表面における皮膜の剥離しようとする部位にその一対の切削具を対向させることにより、その部位の皮膜を剥離することができる。このため、その剥離しようとする部位を線材の周方向に変更しつつ剥離を繰り返すことにより、その線材の全周における皮膜を確実に剥離することができる。このため、例えば、平角線材において、その主面と側面が交差する角部が断面において湾曲し、その湾曲する角部において皮膜が形成されていたとしても、一対の切削具を回転させてそれらの角部皮膜に一対の切削具を対向させることにより、それらの角部皮膜であっても確実に剥離することができる。この結果、本発明の線材の皮膜剥離装置及びその皮膜剥離方法では、線材の全周における皮膜を容易にかつ確実に剥離することができるものとなる。   That is, in the wire film peeling apparatus and the film peeling method according to the present invention, a pair of cutting tools are rotated around the wire rod as a center of rotation, and the pair of cutting tools are opposed to the portions on the surface of the wire to be peeled off. By doing so, the film at the site can be peeled off. For this reason, the film | membrane in the perimeter of the wire can be reliably peeled by repeating peeling, changing the site | part which is going to peel in the circumferential direction of a wire. For this reason, for example, in a flat wire, even if a corner portion where the principal surface and the side surface are curved in a cross section and a film is formed in the curved corner portion, a pair of cutting tools are rotated to rotate them. By facing a pair of cutting tools to the corner film, even those corner films can be reliably peeled off. As a result, in the wire film peeling apparatus and the film peeling method of the present invention, the film on the entire circumference of the wire can be easily and reliably peeled off.

したがって、例えば、図7に示すように、平角線材1の互いに対向する主面1a,1bのそれぞれに一対の切削具31,32を対峙させた状態で、一対の切削具31,32の互いの距離を縮めると、この一対の切削具31,32は、平角線材1の主面1a,1bに形成さえた主面皮膜3a,3b(図8及び図9)に対して平角線材1の外側から中心に向かう切込みを加えることが可能に構成される。一方、図4に示すように、互いに対向する側面1c,1dのそれぞれにこの一対の切削具31,32を対峙させた状態で、一対の切削具31,32の互いの距離を縮めると、この一対の切削具31,32は、平角線材1の側面1c,1dに形成された側面皮膜3c,3d(図5及び図6)に対して平角線材1の外側から中心に向かう切込みを加えることが可能に構成される。そして、一対の切削具31,32が皮膜3に切込みを加えた状態で、切削具相対移動手段60により一対の切削具31,32を線材1の長手方向に移動させることにより、その皮膜3を剥離可能に構成される。   Therefore, for example, as shown in FIG. 7, in a state where the pair of cutting tools 31 and 32 face each other on the principal surfaces 1a and 1b of the flat wire 1 facing each other, When the distance is shortened, the pair of cutting tools 31 and 32 are formed from the outside of the rectangular wire 1 with respect to the main surface coatings 3a and 3b (FIGS. 8 and 9) formed even on the main surfaces 1a and 1b of the flat wire 1. It is possible to make a cut toward the center. On the other hand, as shown in FIG. 4, when the distance between the pair of cutting tools 31 and 32 is reduced in a state where the pair of cutting tools 31 and 32 face each other on the side surfaces 1c and 1d facing each other, The pair of cutting tools 31 and 32 can make a cut from the outer side of the flat wire 1 toward the center with respect to the side coatings 3c and 3d (FIGS. 5 and 6) formed on the side surfaces 1c and 1d of the flat wire 1. Configured to be possible. Then, in a state in which the pair of cutting tools 31 and 32 are cut into the coating 3, the pair of cutting tools 31 and 32 are moved in the longitudinal direction of the wire 1 by the cutting tool relative movement means 60. It is configured to be peelable.

図1〜図3に示すように、線材支持機構21は、支持機構移動手段80を介して基台10aに配置される。この支持機構移動手段80は、基台10a上に配置された土台81と、土台81上に固定され空気供給源から供給される圧縮空気によってロッド83を出没させるシリンダ82と、そのロッド83の先端と線材支持機構21の載置台22を連結する連結具84と、平角線材1の長手方向に沿ってシリンダ82上に配置されたガイドレール85とを備える。線材支持機構21の載置台22の下面22aにはガイドレール85に係合する溝が形成され、載置台22はガイドレール85に沿って移動可能に構成される。このため、ロッド83の出没によって、平角線材1は線材支持機構21にて支持された状態でその長手方向に移動するように構成される。   As shown in FIGS. 1 to 3, the wire support mechanism 21 is disposed on the base 10 a via the support mechanism moving means 80. The support mechanism moving means 80 includes a base 81 disposed on the base 10a, a cylinder 82 that is fixed on the base 81 and causes the rod 83 to be moved in and out by compressed air supplied from an air supply source, and a tip of the rod 83. And a connecting tool 84 for connecting the mounting base 22 of the wire support mechanism 21 and a guide rail 85 arranged on the cylinder 82 along the longitudinal direction of the flat wire 1. A groove that engages with the guide rail 85 is formed on the lower surface 22 a of the mounting base 22 of the wire rod support mechanism 21, and the mounting base 22 is configured to be movable along the guide rail 85. For this reason, the rectangular wire 1 is configured to move in the longitudinal direction in a state where it is supported by the wire support mechanism 21 as the rod 83 moves in and out.

次に、上記皮膜剥離装置を用いた本発明の皮膜剥離方法ついて説明する。   Next, the film peeling method of the present invention using the above film peeling apparatus will be described.

本発明の皮膜剥離方法は、線材1を挟むように対向して設けられた一対の切削具31,32を線材1の外表面に形成された皮膜3に線材1の両側から当接させてその皮膜3に切込みを加え、その皮膜3に切込みを加えた一対の切削具31,32を線材1に対してその長手方向に相対移動させることによって皮膜3を剥離する皮膜剥離工程と、線材1の外面から一対の切削具31,32を離間させて皮膜剥離工程において一対の切削具31,32が皮膜3に切込みを加えた位置まで一対の切削具31,32を戻す切削具戻し工程とを順次繰り返す皮膜剥離方法である。この実施の形態では、線材1が平角線材1である場合であって、その主面皮膜3a,3bの剥離の後に、側面皮膜3c,3dが剥離される場合を代表して説明する。   In the film peeling method of the present invention, a pair of cutting tools 31 and 32 provided to face each other so as to sandwich the wire 1 are brought into contact with the film 3 formed on the outer surface of the wire 1 from both sides of the wire 1. A film peeling step for peeling the film 3 by making a cut in the film 3, and moving the pair of cutting tools 31, 32 with the cut in the film 3 relative to the wire 1 in the longitudinal direction; A cutting tool returning step for separating the pair of cutting tools 31 and 32 from the outer surface and returning the pair of cutting tools 31 and 32 to a position where the pair of cutting tools 31 and 32 cut the coating 3 in the coating film peeling process. This is a repeated film peeling method. In this embodiment, the case where the wire 1 is a flat wire 1 and the side coatings 3c and 3d are peeled off after the main surface coatings 3a and 3b are peeled off will be described as a representative.

このため、先ず、線材送り機構11の一対のローラ13,14を回転させ、その一対のローラ13,14間に平角線材1を案内することによって平角線材1を送り出す。これにより平角線材1は可動台62に設けられたノズル67を貫通し、一対の切削具31,32の間を更に通過して線材支持機構21の載置台22上に案内される。この状態で一対のローラ13,14の回転を止めることにより、平角線材1の送りを止める。なお、平角線材1は、主面1a,1bが一対のローラ13,14に当接する向きにて一対のローラ13,14間に案内されるものとする。   For this reason, first, the pair of rollers 13 and 14 of the wire rod feeding mechanism 11 is rotated, and the rectangular wire 1 is fed by guiding the rectangular wire 1 between the pair of rollers 13 and 14. As a result, the flat wire 1 passes through the nozzle 67 provided on the movable table 62, further passes between the pair of cutting tools 31 and 32, and is guided onto the mounting table 22 of the wire support mechanism 21. In this state, the feed of the rectangular wire 1 is stopped by stopping the rotation of the pair of rollers 13 and 14. The rectangular wire 1 is guided between the pair of rollers 13 and 14 in such a direction that the main surfaces 1a and 1b abut against the pair of rollers 13 and 14.

線材11が線材支持機構21の載置台22上に案内された後には、次に、その線材支持機構21のシリンダ26に圧縮エアを供給してロッド26bを移動させ、ロッド26bの先端に連結された押板23を平角線材1に向かって移動させる。これにより、押板23は、平角線材1の主面1aに当接し平角線材1を載置台22に向かって押圧する。このようにして、平角線材1を、載置台22と押板23の間にて支持し、この線材支持機構21は、平角線材1の皮膜3を剥離するにあたって、線材送り機構11から送られてきた断面が方形を成す平角線材1を、その線材送り機構11とともに水平に支持する。   After the wire 11 is guided onto the mounting table 22 of the wire support mechanism 21, the compressed air is then supplied to the cylinder 26 of the wire support mechanism 21 to move the rod 26b and connected to the tip of the rod 26b. The pressed plate 23 is moved toward the flat wire 1. Thereby, the push plate 23 abuts against the main surface 1 a of the flat wire 1 and presses the flat wire 1 toward the mounting table 22. In this way, the flat wire 1 is supported between the mounting table 22 and the push plate 23, and this wire support mechanism 21 is sent from the wire feed mechanism 11 when peeling the coating 3 of the flat wire 1. A flat wire 1 having a square cross section is supported horizontally together with its wire feed mechanism 11.

その後、切削具相対移動手段60により一対の切削具31,32を、皮膜3を剥離するための端部にまで案内させて維持する。この実施の形態では、図2に示すように、一対の切削具31,32を線材支持機構21側に移動させて維持する場合を示す。次に、図7に示すように、切削具回転手段70により平角線材1の互いに対向する主面1a,1bのそれぞれに一対の切削具31,32を対峙させる。そして、切込み付与手段40,50におけるサーボモータ43,53を駆動し、そのサーボモータ43,53の回転軸43a,53aに偏倚して設けられたカム部材44,54を図の実線矢印で示すように回転させる。そして、カム部材44,54に接触する移動台42,52をレール41,51に沿って移動させ、その移動台42,52に取付けられた一対の切削具31,32の互いの距離を縮める。   Thereafter, the pair of cutting tools 31 and 32 are guided and maintained by the cutting tool relative movement means 60 to the end for peeling the coating 3. In this embodiment, as shown in FIG. 2, the case where a pair of cutting tools 31 and 32 are moved to the wire support mechanism 21 side and maintained is shown. Next, as shown in FIG. 7, a pair of cutting tools 31 and 32 are caused to face each other on the principal surfaces 1 a and 1 b of the flat wire 1 facing each other by the cutting tool rotating means 70. Then, the servo motors 43 and 53 in the incision applying means 40 and 50 are driven, and cam members 44 and 54 which are provided biased to the rotation shafts 43a and 53a of the servo motors 43 and 53 are indicated by solid line arrows in the figure. Rotate to And the moving bases 42 and 52 which contact the cam members 44 and 54 are moved along the rails 41 and 51, and the mutual distance of a pair of cutting tools 31 and 32 attached to the moving bases 42 and 52 is shortened.

これにより、一対の切削具31,32における切削歯31a,32aは、図8に示すように線材11から離間した状態から移動してそれぞれ平角線材1の主面1a,1bに当接し、図9に示すように、平角線材1の外側から中心に向かって主面皮膜3a,3bに食い込む。そして、主面皮膜3a,3bの厚さに相当する深さまで切削歯31a,32aを食い込ませる。ここで、主面皮膜3a,3bに加える切込みの深さは、サーボモータ43,53の回転軸43a,53aに偏倚して設けられたカム部材44,54の回転量を調整することによって制御される。   As a result, the cutting teeth 31a and 32a in the pair of cutting tools 31 and 32 move from a state of being separated from the wire 11 as shown in FIG. 8, and abut against the main surfaces 1a and 1b of the flat wire 1 respectively. As shown in FIG. 2, the main wire films 3a and 3b bite into the center from the outside of the flat wire 1. Then, the cutting teeth 31a and 32a are bitten to a depth corresponding to the thickness of the main surface coatings 3a and 3b. Here, the depth of incision to be applied to the main surface coatings 3a and 3b is controlled by adjusting the amount of rotation of the cam members 44 and 54 provided in a biased manner on the rotation shafts 43a and 53a of the servomotors 43 and 53. The

次に、一対の切削具31,32の切削歯31a,32aが平角線材1の主面皮膜3a,3bに食い込んだ図9に示す状態から、切削具相対移動手段60におけるサーボモータ64を駆動することによってボールねじ63を回転させ、そのボールねじ63に螺合する可動台62を線材1の長手方向に移動させる。即ち、可動台62を移動させることによって、その可動台62に、切削具回転手段70を介して設けられた一対の切削具31,32を線材1の長手方向に移動させる。この実施の形態では、図2の実線矢印で示すように、一対の切削具31,32を線材支持機構21から遠ざける方向に移動させる場合を示す。これにより、一対の切削具31,32の平角線材1に対する線材1の長手方向の相対位置は変化し、一対の切削具31,32の切削歯31a,32aを線材1の長手方向に相対移動する。線材支持機構21の移動距離は、平角線材1に形成する剥離部の所望長さに相当する値に設定され、その移動量に到達することによって、図10に示すように、平角線材1の主面1a,1bにおける主面皮膜3a,3bはその一対の切削具31,32により所定長さ剥離される。   Next, the servo motor 64 in the cutting tool relative movement means 60 is driven from the state shown in FIG. 9 in which the cutting teeth 31a and 32a of the pair of cutting tools 31 and 32 bite into the main surface coatings 3a and 3b of the flat wire 1. As a result, the ball screw 63 is rotated, and the movable base 62 screwed into the ball screw 63 is moved in the longitudinal direction of the wire 1. That is, by moving the movable table 62, the pair of cutting tools 31 and 32 provided on the movable table 62 via the cutting tool rotating means 70 are moved in the longitudinal direction of the wire 1. In this embodiment, as shown by the solid line arrows in FIG. 2, the pair of cutting tools 31 and 32 are moved in a direction away from the wire rod support mechanism 21. Thereby, the relative position in the longitudinal direction of the wire rod 1 with respect to the flat wire 1 of the pair of cutting tools 31 and 32 is changed, and the cutting teeth 31 a and 32 a of the pair of cutting tools 31 and 32 are relatively moved in the longitudinal direction of the wire rod 1. . The moving distance of the wire support mechanism 21 is set to a value corresponding to the desired length of the peeled portion formed on the flat wire 1, and by reaching the moving amount, as shown in FIG. The main surface coatings 3a and 3b on the surfaces 1a and 1b are separated by a predetermined length by the pair of cutting tools 31 and 32.

このような皮膜剥離工程の後には、線材1の外面から一対の切削具31,32を離間させ、更に先の皮膜剥離工程において一対の切削具31,32が皮膜3に切込みを加えた位置まで一対の切削具31,32を戻す切削具戻し工程が行われる。この実施の形態では、この切削具戻し工程において、図2に示すように、一対の切削具31,32を線材支持機構21側にまで移動させて維持する場合を示す。   After such a film peeling step, the pair of cutting tools 31 and 32 are separated from the outer surface of the wire 1, and further to the position where the pair of cutting tools 31 and 32 cut the film 3 in the previous film peeling step. A cutting tool returning step for returning the pair of cutting tools 31 and 32 is performed. In this embodiment, in this cutting tool returning step, as shown in FIG. 2, a pair of cutting tools 31, 32 are moved to the wire support mechanism 21 side and maintained.

この切削具戻し工程を具体的に説明する。即ち、平角線材1の主面皮膜3a,3bを剥離する上述した先の皮膜剥離工程の後、切込み付与手段40,50におけるサーボモータ43,53を駆動し、そのサーボモータ43,53の回転軸43a,53aに偏倚して設けられたカム部材44,54を逆転させる。そして、カム部材44,54に接触する移動台42,52をレール41,51に沿って逆方向に移動させ、その移動台42,52に取付けられた一対の切削具31,32の互いの距離を拡大させる。これにより、一対の切削具31,32における切削歯31a,32aを、図8に示すように線材11から離間させた状態とする。そして、切削具相対移動手段60におけるサーボモータ64を駆動することによってボールねじ63を逆方向に回転させ、そのボールねじ63に螺合する可動台62を移動させることによって、その可動台62に、切削具回転手段70を介して設けられた一対の切削具31,32を、その一対の切削具31,32が先の皮膜剥離工程において最初に皮膜3に切込みを加えた図2に示す位置まで戻す。   This cutting tool returning step will be specifically described. That is, after the above-described film peeling step for peeling the main surface films 3a and 3b of the rectangular wire 1, the servo motors 43 and 53 in the incision applying means 40 and 50 are driven, and the rotation shafts of the servo motors 43 and 53 are driven. The cam members 44 and 54 provided to be biased to 43a and 53a are reversed. Then, the moving bases 42 and 52 that come into contact with the cam members 44 and 54 are moved in the opposite direction along the rails 41 and 51, and the mutual distance between the pair of cutting tools 31 and 32 attached to the moving bases 42 and 52. To enlarge. As a result, the cutting teeth 31a and 32a of the pair of cutting tools 31 and 32 are in a state of being separated from the wire 11 as shown in FIG. Then, by driving the servo motor 64 in the cutting tool relative movement means 60, the ball screw 63 is rotated in the reverse direction, and the movable table 62 that is screwed to the ball screw 63 is moved. The pair of cutting tools 31 and 32 provided via the cutting tool rotating means 70 is moved to the position shown in FIG. 2 where the pair of cutting tools 31 and 32 first cut the film 3 in the previous film peeling step. return.

そして、本発明の特徴ある点は、この切削具戻し工程において線材1を回転中心として線材1を挟むように対向して設けられた一対の切削具31,32を回転させるところにある。具体的には、電動モータ72により、その線材1を回転中心として線材1が貫通しかつ一対の切削具31,32が設けられた回転部材71を回転させることにより、その線材1を回転中心として一対の切削具31,32を回転させる。その後、皮膜剥離工程が再び行われるけれども、先の皮膜剥離工程において平角線材1の主面皮膜3a,3bを剥離したので、今回の皮膜剥離工程において平角線材1の側面皮膜3c,3dを剥離する場合を示す。   And the characteristic point of this invention exists in the place which rotates a pair of cutting tools 31 and 32 provided facing so that the wire 1 may be pinched | interposed in the cutting tool return process by using the wire 1 as a rotation center. Specifically, the electric motor 72 rotates the rotating member 71 in which the wire 1 penetrates and the pair of cutting tools 31 and 32 are provided with the wire 1 as the rotation center, so that the wire 1 is set as the rotation center. The pair of cutting tools 31 and 32 are rotated. Thereafter, although the film peeling process is performed again, the main surface films 3a and 3b of the flat wire 1 are peeled in the previous film peeling process, so that the side films 3c and 3d of the flat wire 1 are peeled in this film peeling process. Show the case.

即ち、切削具戻し工程において線材1を回転中心として一対の切削具31,32を回転させ、先の皮膜剥離工程においては、図7に示すように平角線材1の互いに対向する主面1a,1bのそれぞれに一対の切削具31,32が対峙していたけれども、そこから約90度回転部材71を回転させ、図4に示すように、その主面1a,1bに直交して互いに対向する側面1c,1dのそれぞれにこの一対の切削具31,32を対峙させる。そして、再び皮膜剥離工程を行う。   That is, in the cutting tool returning step, the pair of cutting tools 31 and 32 are rotated around the wire 1 as the center of rotation, and in the previous film peeling step, the main surfaces 1a and 1b of the rectangular wire 1 facing each other as shown in FIG. Although the pair of cutting tools 31 and 32 face each other, the rotating member 71 is rotated about 90 degrees therefrom, and as shown in FIG. 4, the side surfaces orthogonal to the main surfaces 1a and 1b face each other. The pair of cutting tools 31 and 32 are opposed to 1c and 1d, respectively. Then, the film peeling process is performed again.

再び行われる皮膜剥離工程にあっては、先ず、切込み付与手段40,50におけるサーボモータ43,53を駆動し、カム部材44,54を回転させ、移動台42,52に取付けられた一対の切削具31,32の互いの距離を縮める。これにより、図5に示すように主面1a,1bに直交して互いに対向する側面1c,1dのそれぞれに対向する一対の切削具31,32を側面1c,1dに形成された側面皮膜3c,3dに当接させる。そして、図6に示すように一対の切削具31,32の互いの距離を更に縮めてその側面皮膜3c,3dに切込みを加える。ここで、側面皮膜3c,3dに加える切込みの深さは、サーボモータ43,53の回転軸43a,53aに偏倚して設けられたカム部材44,54の回転量を調整することによって制御される。   In the film peeling process to be performed again, first, the servo motors 43 and 53 in the incision applying means 40 and 50 are driven, the cam members 44 and 54 are rotated, and a pair of cuttings attached to the movable bases 42 and 52 are performed. The distance between the tools 31 and 32 is reduced. Thereby, as shown in FIG. 5, a pair of cutting tools 31 and 32 facing each of the side surfaces 1c and 1d orthogonal to the main surfaces 1a and 1b are formed on the side surfaces 1c and 1d. 3d is contacted. Then, as shown in FIG. 6, the distance between the pair of cutting tools 31 and 32 is further reduced, and the side coatings 3 c and 3 d are cut. Here, the depths of the cuts applied to the side films 3c and 3d are controlled by adjusting the amount of rotation of the cam members 44 and 54 provided in a biased manner on the rotating shafts 43a and 53a of the servomotors 43 and 53. .

そして、切削具相対移動手段60におけるサーボモータ64を駆動することによってボールねじ63を回転させ、そのボールねじ63に螺合する可動台62を線材1の長手方向に移動させる。即ち、可動台62を移動させることによって、その可動台62に、切削具回転手段70を介して設けられた一対の切削具31,32を線材1の長手方向に移動させる。このようにして、後側面皮膜3c,3dに切込みを加えた一対の切削具31,32を線材1に対して線材1の長手方向に相対移動させることにより、その側面皮膜3c,3dの剥離を行う。   Then, the ball screw 63 is rotated by driving the servo motor 64 in the cutting tool relative moving means 60, and the movable base 62 screwed to the ball screw 63 is moved in the longitudinal direction of the wire 1. That is, by moving the movable table 62, the pair of cutting tools 31 and 32 provided on the movable table 62 via the cutting tool rotating means 70 are moved in the longitudinal direction of the wire 1. In this way, the pair of cutting tools 31 and 32 in which the rear side coatings 3c and 3d are cut are moved relative to the wire 1 in the longitudinal direction of the wire 1 so that the side coatings 3c and 3d are peeled off. Do.

従って、本発明の皮膜剥離装置10によれば、一対の切削具31,32を平角線材1の外側から中心に向かって移動させることによって皮膜3に切込みを加えるため、皮膜3の厚さに合わせて一対の切削具31,32による切込み量を調節することができる。そして、皮膜3に切込みを加えた一対の切削具31,32を線材1に対して長手方向に相対移動させて皮膜3を剥離するため、その相対移動の長さを調節することによって剥離部の長さを自由に設定することができる。したがって、皮膜3の厚さ及び剥離部の長さに応じて一対の切削具31,32を変更する必要がなく作業効率が良く、皮膜3を所望の長さで容易に剥離することができる。   Therefore, according to the film peeling apparatus 10 of the present invention, since the pair of cutting tools 31 and 32 are moved from the outside of the flat wire 1 toward the center, the film 3 is cut, so that the thickness of the film 3 is adjusted. Thus, the cutting amount by the pair of cutting tools 31 and 32 can be adjusted. And since the pair of cutting tools 31 and 32 which added the cut | disconnection to the membrane | film | coat 3 are moved relative to the wire 1 in the longitudinal direction and the membrane | film | coat 3 is peeled, the length of the peeling part is adjusted by adjusting the length of the relative movement. The length can be set freely. Therefore, it is not necessary to change the pair of cutting tools 31 and 32 according to the thickness of the coating 3 and the length of the peeling portion, and the working efficiency is good, and the coating 3 can be easily peeled at a desired length.

平角線材1の皮膜3を剥離するこの実施の形態では、上述したように皮膜剥離工程を2回繰り返すことにより、図10に示すように、平角線材1の主面皮膜3a,3bと側面皮膜3c,3dの双方を剥離することができる。そして、皮膜3が除去された部分は、導体部2が露出した状態となる。このため、この導体部2を後工程においてボビンやステータコアに設けられた端子に絡げることによって平角線材1と端子との電気的接触を確保することができる。よって、皮膜3を除去した後、一対の切削具31,32を平角線材1から遠ざけ、それと同時に又はその後、線材送り機構11における一対のローラ13,14を回転させ、平角線材1を送り出すとともに、それと同期して支持機構移動手段80により平角線材1を拘束する線材支持機構21を同方向に移動させ、次に皮膜3を剥離する箇所までその線材1を移動させる。   In this embodiment in which the film 3 of the flat wire 1 is peeled off, the film peeling process is repeated twice as described above, so that the main surface films 3a and 3b and the side surface film 3c of the flat wire 1 are shown in FIG. , 3d can be peeled off. And the part from which the film | membrane 3 was removed will be in the state which the conductor part 2 exposed. For this reason, the electrical contact between the flat wire 1 and the terminal can be ensured by tying the conductor portion 2 to a terminal provided on the bobbin or the stator core in a subsequent process. Therefore, after removing the coating 3, the pair of cutting tools 31 and 32 are moved away from the flat wire 1 and simultaneously or thereafter, the pair of rollers 13 and 14 in the wire feed mechanism 11 are rotated to feed out the flat wire 1; In synchronization with this, the wire support mechanism 21 that restrains the flat wire 1 is moved in the same direction by the support mechanism moving means 80, and then the wire 1 is moved to a position where the coating 3 is peeled off.

この次に皮膜3を剥離する箇所までの線材1の移動にあって、支持機構移動手段80による移動では足りない場合には、線材支持機構21におけるシリンダ26によりそのロッド26bを没入して押板23を上昇させ、平角線材1の拘束を解除しても良い。この場合には、線材送り機構11における一対のローラ13,14を回転させ、平角線材1を送り出すことにより、その線材11の次に皮膜3を剥離する箇所までの移動が行われることになる。   Next, when the wire 1 is moved to the location where the coating 3 is peeled off and the movement by the support mechanism moving means 80 is not sufficient, the rod 26b is immersed by the cylinder 26 in the wire support mechanism 21 and the push plate is moved. 23 may be raised to release the restraint of the flat wire 1. In this case, by rotating the pair of rollers 13 and 14 in the wire feed mechanism 11 and feeding the flat wire 1, the wire 11 is moved to the location where the coating 3 is peeled next.

ここで、上述した皮膜剥離装置10の動作は、皮膜剥離装置10に搭載された図示しないコントローラによって、自動制御されるものである。   Here, the operation of the film peeling apparatus 10 described above is automatically controlled by a controller (not shown) mounted on the film peeling apparatus 10.

上述したように、本発明の線材の皮膜剥離装置10及びその皮膜剥離方法では、線材1を回転中心として一対の切削具31,32を回転させるので、対向する両主面1a,1bにおける皮膜3a,3bをそれぞれ剥離した後、最初に皮膜に切込みを加えた位置まで一対の切削具31,32を戻すとともに、線材1を回転中心としてその一対の切削具31,32を回転させて、その線材1の両側面1c,1dに対向させるようにすれば、その平角線材1の対向する両側面1c,1dに一対の切削具31,32を当接させて切込みを加え、その後その一対の切削具31,32を再び線材に対して長手方向に移動させることによって、線材1の対向する両側面1c,1dにおける皮膜3c,3dをそれぞれ剥離することができる。   As described above, in the wire film peeling apparatus 10 and the film peeling method thereof according to the present invention, the pair of cutting tools 31 and 32 are rotated about the wire 1 as the center of rotation, and thus the film 3a on the opposing main surfaces 1a and 1b. , 3b, and then the pair of cutting tools 31, 32 are returned to the position where the cut is first made in the film, and the pair of cutting tools 31, 32 are rotated around the wire 1 as the center of rotation. If the two side surfaces 1c and 1d are opposed to each other, the pair of cutting tools 31 and 32 are brought into contact with the opposite side surfaces 1c and 1d of the flat wire 1 to make a cut, and then the pair of cutting tools By moving 31 and 32 again in the longitudinal direction with respect to the wire, the coatings 3c and 3d on the opposite side surfaces 1c and 1d of the wire 1 can be peeled off, respectively.

即ち、本発明の線材の皮膜剥離装置10及びその皮膜剥離方法では、線材1を回転中心として一対の切削具31,32を回転させて、線材1の表面における皮膜3の剥離しようとする部位にその一対の切削具31,32を対向させることにより、その部位の皮膜3を剥離することができる。このため、その剥離しようとする部位を周方向に変更しつつ皮膜3の剥離を繰り返すことにより、その線材1の全周における皮膜3を確実に剥離することができるものとなる。   That is, in the wire film peeling apparatus 10 and the film peeling method of the present invention, the pair of cutting tools 31 and 32 are rotated around the wire 1 as a center of rotation, so that the film 3 on the surface of the wire 1 is to be peeled off. By making the pair of cutting tools 31 and 32 face each other, the coating 3 at that portion can be peeled off. For this reason, by repeatedly peeling the coating 3 while changing the portion to be peeled in the circumferential direction, the coating 3 on the entire circumference of the wire 1 can be reliably peeled off.

従って、上述した実施の形態では、皮膜剥離工程を2回繰り返すことにより、図10に示すように、平角線材1の主面皮膜3a,3bと側面皮膜3c,3dの双方を剥離することができる場合を例示したけれども、主面1a,1bと側面1c,1dが交差する角部が断面において湾曲していたり、断面形状が円形を成す線材1のように、皮膜剥離工程を2回繰り返しても、表面に形成された皮膜3の全てを剥離し難いような場合には、皮膜剥離工程を3回又は4回以上繰り返すことによりその線材1の全周における皮膜3を確実に剥離することができる。   Therefore, in the above-described embodiment, by repeating the film peeling step twice, as shown in FIG. 10, both the main surface films 3a and 3b and the side surface films 3c and 3d of the flat wire 1 can be peeled. Although the case is illustrated, even if the film peeling process is repeated twice, as in the case of the wire 1 in which the corners where the main surfaces 1a, 1b and the side surfaces 1c, 1d intersect are curved in the cross section or the cross section has a circular shape, When it is difficult to peel all the film 3 formed on the surface, the film 3 on the entire circumference of the wire 1 can be surely peeled by repeating the film peeling step three times or four times or more. .

皮膜剥離工程を3回行って、平角線材1の角部における皮膜3の全てを剥離する場合を図11に例示する。この剥離方法では、1回目の剥離工程において、図11(a)に示すように対向する角部1e,1fに形成された皮膜3e,3fとともに側面皮膜3c,3dの一部を剥離し、2回目の剥離工程において、図11(b)に示すように別の対向する角部1g,1hに形成された皮膜3g,3hとともに側面皮膜3c,3dの残部を剥離する。そして、3回目の剥離工程において、図11(c)に示すように主面皮膜3a,3bを剥離することにより、図12に示すように、その線材1の全周における皮膜3を確実に剥離することができる。   FIG. 11 illustrates a case where the film peeling step is performed three times to peel off all of the film 3 at the corners of the flat wire 1. In this peeling method, in the first peeling step, as shown in FIG. 11A, a part of the side surface films 3c and 3d is peeled off together with the films 3e and 3f formed on the opposite corners 1e and 1f. In the second stripping step, the remaining portions of the side coatings 3c and 3d are stripped together with the coatings 3g and 3h formed on the other opposing corners 1g and 1h as shown in FIG. 11 (b). Then, in the third peeling step, the main surface coatings 3a and 3b are peeled off as shown in FIG. 11 (c), thereby reliably peeling off the coating 3 on the entire circumference of the wire 1 as shown in FIG. can do.

また、皮膜剥離工程を4回行って、断面形状が円形を成す線材1における皮膜3の全てを剥離する場合を図13及び図14に例示する。この剥離方法では、1回目の剥離工程において、図13(a)に示すように直径方向に対向する部位に形成された皮膜3を導体部2の極一部とともに剥離して第1及び第2剥離面4a,4bを形成し、2回目の剥離工程において、図13(b)に示すように第1及び第2剥離面4a,4bと直交する位置に形成された皮膜3を導体部2の極一部とともに剥離して第3及び第4剥離面4c,4dを形成する。   Moreover, the case where the film peeling process is performed four times to peel all the film 3 in the wire 1 having a circular cross-sectional shape is illustrated in FIGS. 13 and 14. In this stripping method, in the first stripping process, the coating 3 formed on the diametrically opposed portion as shown in FIG. The peeling surfaces 4a and 4b are formed, and in the second peeling process, the coating 3 formed at a position orthogonal to the first and second peeling surfaces 4a and 4b is formed on the conductor portion 2 as shown in FIG. The third and fourth peeling surfaces 4c and 4d are formed by peeling together with a part of the pole.

また、3回目の剥離工程において、図14(a)に示すように、第1剥離面4aと第3剥離面4cの間の角部における皮膜3と第2剥離面4bと第4剥離面4dの間の角部における皮膜3を導体部2の極一部とともに剥離して第5及び第6剥離面4e,4fを形成する。そして、4回目の剥離工程において、図14(b)に示すように、第2剥離面4bと第3剥離面4cの間の角部における皮膜3と第1剥離面4aと第4剥離面4dの間の角部における皮膜3を導体部2の極一部とともに剥離して第7及び第8剥離面4g,4hを形成する。これにより、図15に示すように、断面が円形を成す線材1の全周における皮膜3を確実に剥離することができる。このように、皮膜剥離工程を繰り返す回数を増加させることにより、剥離後の線材1の断面形状は、その剥離工程の数の2倍の数の多角形となり、断面形状が円形を成す線材1の皮膜3であっても、その線材1の全周における皮膜3を確実に剥離することができる。   In the third peeling step, as shown in FIG. 14A, the film 3, the second peeling surface 4b, and the fourth peeling surface 4d at the corners between the first peeling surface 4a and the third peeling surface 4c. The coating 3 at the corner between the two is peeled off together with a part of the conductor 2 to form fifth and sixth peeled surfaces 4e and 4f. Then, in the fourth peeling step, as shown in FIG. 14B, the coating 3, the first peeling surface 4a, and the fourth peeling surface 4d at the corners between the second peeling surface 4b and the third peeling surface 4c. The film 3 at the corner between the two is peeled off together with a part of the conductor 2 to form seventh and eighth peeled surfaces 4g and 4h. As a result, as shown in FIG. 15, the coating 3 on the entire circumference of the wire 1 having a circular cross section can be reliably peeled off. Thus, by increasing the number of times of repeating the film peeling step, the cross-sectional shape of the wire 1 after peeling becomes a polygon twice as many as the number of peeling steps, and the cross-sectional shape of the wire 1 having a circular shape is reduced. Even if it is the film | membrane 3, the film | membrane 3 in the perimeter of the wire 1 can be peeled reliably.

なお、上述した実施の形態では、線材1の種類として断面形状が長方形である平角線材1の主面皮膜3a,3bの剥離の後に、側面皮膜3c,3dが剥離される場合について説明したけれども、側面皮膜3c,3dの剥離の後に、主面皮膜3a,3bを剥離しても良く、断面形状が正方形である線材1の皮膜3を剥離するようにしても良い。   In the above-described embodiment, the case where the side surface coatings 3c and 3d are peeled after the peeling of the main surface coatings 3a and 3b of the rectangular wire 1 having a rectangular cross-sectional shape as the type of the wire 1 is described. After the side films 3c and 3d are peeled off, the main face films 3a and 3b may be peeled off, or the film 3 of the wire 1 having a square cross section may be peeled off.

また、上述した実施の形態では、切込み付与手段40,50を移動させる機構を設け、一対の切削具31,32を平角線材1に対して移動させたけれども、一対の切削具31,32を平角線材1に対して線材1の長手方向に相対移動させる構成であれば、平角線材1を一対の切削具31,32に対して移動させる支持機構移動手段80により、一対の切削具31,32を平角線材1に対して線材1の長手方向に相対移動させても良い。   In the above-described embodiment, a mechanism for moving the incision imparting means 40 and 50 is provided and the pair of cutting tools 31 and 32 are moved with respect to the flat wire 1, but the pair of cutting tools 31 and 32 are flat. If the configuration is such that the wire 1 is moved relative to the longitudinal direction of the wire 1, the pair of cutting tools 31, 32 are moved by the support mechanism moving means 80 that moves the flat wire 1 relative to the pair of cutting tools 31, 32. The rectangular wire 1 may be moved relative to the longitudinal direction of the wire 1.

また、上述した実施の形態では、載置台22と押板23にて線材1を挟む線材支持手段21を用いて説明したが、この皮膜剥離装置10に例えば線材支持手段を有する巻線機を連結し、その巻線機における線材支持手段を本発明の皮膜剥離装置10における線材支持手段としても良い。このように本発明の皮膜剥離装置10に他の装置を連結して重複した装置を兼用すれば、設備全体における費用の低減化が成される。   In the above-described embodiment, the wire support means 21 sandwiching the wire 1 between the mounting table 22 and the push plate 23 has been described. However, for example, a winding machine having a wire support means is connected to the film peeling device 10. The wire support means in the winding machine may be used as the wire support means in the film peeling apparatus 10 of the present invention. In this way, if another apparatus is connected to the film peeling apparatus 10 of the present invention to serve as an overlapping apparatus, the cost of the entire facility can be reduced.

また、上述した実施の形態では、一対の切削具31,32を移動させる機構としてサーボモータ43,53,64を用い、回転部材71を回転させる機構として電動モータ72を用いたけれども、これらの移動又は回転機構としてエア圧や油圧等により駆動する流体圧シリンダを用いても良い。   In the above-described embodiment, the servo motors 43, 53, 64 are used as the mechanism for moving the pair of cutting tools 31, 32, and the electric motor 72 is used as the mechanism for rotating the rotating member 71. Alternatively, a fluid pressure cylinder driven by air pressure or hydraulic pressure may be used as the rotation mechanism.

更に、上述した実施の形態では、切込み付与手段40,50におけるカム部材44,54として、その外周に切削具31,32が取付けられた移動台42,52が接触するいわゆる板カム(周縁カム)である場合を説明した。けれども、図16及び図17に示すように、このカム部材44,54はその正面に回転中心から偏倚する円形又は楕円形の凹溝44a,54aが形成されたいわゆる正面カム(溝カム)ものであっても良い。この場合、その凹溝44a,54aに進入してその凹溝44a,54aの軌跡に沿って移動台42,52を移動させる係合片42a,52aがその移動台42,52に設けられる。   Further, in the above-described embodiment, as the cam members 44 and 54 in the incision imparting means 40 and 50, so-called plate cams (peripheral cams) with which the movable bases 42 and 52 having the cutting tools 31 and 32 attached to the outer periphery come into contact. Explained the case. However, as shown in FIGS. 16 and 17, the cam members 44 and 54 are so-called front cams (groove cams) in which circular or elliptical concave grooves 44a and 54a deviating from the center of rotation are formed on the front surfaces thereof. There may be. In this case, engaging pieces 42a, 52a that enter the concave grooves 44a, 54a and move the movable bases 42, 52 along the locus of the concave grooves 44a, 54a are provided on the movable bases 42, 52.

このような正面カム(溝カム)から成るカム部材44,54を用いても、サーボモータ43,53を駆動してそのカム部材44,54を回転させると、その凹溝44a,54aに進入してその凹溝44a,54aの軌跡に沿って移動する係合片42a,52aとともに、その移動台42,52もレール41,51に沿って移動し、その移動台42,52に取付けられた一対の切削具31,32の互いの距離を縮めることができる。一方、サーボモータ43,53によりこのカム部材44,54を逆転させれば、その凹溝44a,54aに進入してその凹溝44a,54aの軌跡に沿って移動する係合片42a,52aとともに、その移動台42,52もレール41,51に沿って逆方向に移動し、その移動台42,52に取付けられた一対の切削具31,32の互いの距離を拡大させることができる。このため、このような正面カム(溝カム)から成るカム部材44,54を用いた場合には、各レール41,51に沿って各移動台42,52の互いの間隔を拡大させる方向に付勢する付勢手段としての図4に示すスプリング46,56のようなものは不要になる。   Even when the cam members 44 and 54 composed of such front cams (groove cams) are used, when the servo motors 43 and 53 are driven to rotate the cam members 44 and 54, they enter the concave grooves 44a and 54a. Along with the engaging pieces 42a and 52a moving along the trajectory of the concave grooves 44a and 54a, the moving bases 42 and 52 also move along the rails 41 and 51 and are attached to the moving bases 42 and 52, respectively. The distance between the cutting tools 31 and 32 can be reduced. On the other hand, when the cam members 44 and 54 are reversed by the servo motors 43 and 53, together with the engaging pieces 42a and 52a that enter the concave grooves 44a and 54a and move along the locus of the concave grooves 44a and 54a. The moving bases 42 and 52 also move in the opposite direction along the rails 41 and 51, and the distance between the pair of cutting tools 31 and 32 attached to the moving bases 42 and 52 can be increased. For this reason, when the cam members 44 and 54 composed of such front cams (groove cams) are used, they are attached along the rails 41 and 51 in the direction in which the distance between the movable bases 42 and 52 is increased. The springs 46 and 56 shown in FIG. 4 as the biasing means for biasing are unnecessary.
