　請求項１の発明によれば、作業者が機械本体へアクセスするための機械本体ドアを開閉する際に向き合う面と、作業者がワークを搬入，搬出するための段取りドアを開閉する際に向き合う面とが斜めに交差するように配置されているので、機械本体ドアの前に立って機械本体にアクセスする作業者と、段取りドアの前に立ってワークの段取り作業を行う作業者とが干渉するのを回避できる。従って機械本体のメンテナンス中であってもワーク段取り作業を支障なく行うことができる。 According to the first aspect of the present invention, the face that faces when the operator opens and closes the machine body door for accessing the machine body, and the face that faces when the worker opens and closes the setup door for loading and unloading the workpiece. Since it is arranged so that the surface intersects diagonally, the worker who stands in front of the machine body door and accesses the machine body interferes with the worker who stands in front of the setup door and performs work setup work. Can be avoided. Accordingly, the work setup work can be performed without any trouble even during the maintenance of the machine body.
　また機械本体ドアと段取りドアとを同一直線をなすように隣接配置した場合に比較して、一方のドアが他方のドアに対して斜めになっている分だけ機械全体の幅を小さくできる。 Also, compared to the case where the machine body door and the setup door are arranged adjacent to each other so as to form the same straight line, the width of the entire machine can be reduced by the amount that one door is inclined with respect to the other door.
　また請求項２の発明によれば、作業者が機械本体ドアの開閉時に向き合う面を主軸の軸線と略平行とし、作業者が段取りドア開閉時に向き合う面を前記軸線に対して斜めに配置したので、前記請求項１の構成を支障なく実現でき、該請求項１の作用効果を確実に得ることができる。 According to the second aspect of the present invention, the surface that the operator faces when opening and closing the machine body door is substantially parallel to the axis of the main shaft, and the surface that the operator faces when opening and closing the setup door is arranged obliquely with respect to the axis. Thus, the configuration of claim 1 can be realized without hindrance, and the function and effect of claim 1 can be obtained with certainty.
　請求項３の発明によれば、ワーク交換装置を、機械本体に第１位置から第２位置へと移動可能に設けられた第１ワーク交換部と、該第１ワーク交換部に第３位置から第４位置へと移動可能に設けられた第２ワーク交換部とを有するとしたので、段取り部に搬入されたワークの、ワーク保持部が保持可能の位置への移動経路の自由度を向上できる。 According to invention of Claim 3, a workpiece | work exchange apparatus is provided in the machine main body so that a movement from the 1st position to the 2nd position was possible, and this 1st workpiece | work exchange part was moved from the 3rd position. Since it has the 2nd work exchange part provided so that movement to the 4th position was possible, the freedom degree of the movement path of the work carried in to the setup part to the position where the work holding part can be held can be improved. .
また、第１ワーク交換部の第１位置から第２位置への移動と、第２ワーク交換部の第３位置から第４位置への移動とを連動させて、つまり第１位置から第２位置への移動と第３位置から第４位置への移動を同時進行的に行うようにしたので、段取り部に搬入されたワークをワーク保持部が保持可能の位置に短時間で移動させることができる。例えば従来装置のように、中立位置とワーク供給位置との間で前進又は後退させ、続いて前記中立位置とワーク渡し位置との間で回動させる場合はそれだけワーク交換に要する時間が長くなる。 In addition, the movement of the first workpiece exchange unit from the first position to the second position and the movement of the second workpiece exchange unit from the third position to the fourth position are linked, that is, from the first position to the second position. Since the movement to the position and the movement from the third position to the fourth position are performed at the same time, the work carried into the setup section can be moved to a position where the work holding section can hold it in a short time. . For example, as in the case of the conventional apparatus, when advancing or retreating between the neutral position and the workpiece supply position and subsequently rotating between the neutral position and the workpiece transfer position, the time required for exchanging the workpiece is increased accordingly.
　また、機械本体に第１ワーク交換部を設け、該第１ワーク交換部に第２ワーク交換部を設けたので、従来装置のように、ワーク搬入装置とワーク搬出装置を別個独立に設けた場合に比較して機械全体を小型化できる。 In addition, when the machine main body is provided with the first work changer and the first work changer is provided with the second work changer, the work loading device and the work unloading device are provided separately as in the conventional device. Compared to, the entire machine can be downsized.
　請求項４の発明によれば、前記第１ワーク交換部は、ワークを保持して回転駆動する主軸の軸線を含む平面と平行な第１平面上で動作を行い、前記第２ワーク交換部は、前記第１平面に直交する第２平面上で動作を行うようにしたので、第１ワーク交換部の動作と第２ワーク交換部の動作とを、互いに干渉することなく連動させることができ、ワーク交換時間を確実に短縮できる。 According to the invention of claim 4, the first work exchanging section operates on a first plane parallel to a plane including the axis of the main shaft that holds and rotates the work, and the second work exchanging section is Since the operation is performed on the second plane orthogonal to the first plane, the operation of the first workpiece exchange unit and the operation of the second workpiece exchange unit can be interlocked without interfering with each other, Work replacement time can be shortened reliably.
　請求項５の発明によれば、複数の工作機械を、作業者が機械本体ドアを開閉する際に向き合う面が互いに平行で、かつ作業者が段取りドアを開閉する際に向き合う面が同一直線上に位置するように配置したので、前記各工作機械の配置間隔を狭くしても作業者が機械本体ドアの前に立って機械本体にアクセスする場合に必要な空間を確保し易い。従って必要な機械台数を確保しつつ、加工ライン長を短縮できる。 According to the fifth aspect of the present invention, a plurality of machine tools are configured such that the surfaces facing when the operator opens and closes the machine body door are parallel to each other, and the surfaces facing when the operator opens and closes the setup door are collinear. Therefore, even if the interval between the machine tools is narrowed, it is easy to secure a necessary space when an operator stands in front of the machine body door and accesses the machine body. Therefore, the processing line length can be shortened while ensuring the necessary number of machines.

On the other hand, the body cover 7 is formed in a rectangular shape in plan view, and is arranged so that its long side forms 90 ° with respect to the arrangement line L.
そして前記ベッド４及び前記機体カバー７には作業者M1が機械本体３ａのメンテナンス等を行う際に位置する作業スペースＡが、前記長方形のコーナ部を切り欠くようにして形成されている。また前記機体カバー７の前記作業スペースＡ部分には、作業者M1が機械本体３ａのメンテナンス等を行う際に前記主軸台５や刃物台６等にアクセスするための開口７ａが形成されており、この開口７ａは左右にスライド可能に配設された機械本体ドア８で開閉される。 A working space A is formed in the bed 4 and the machine body cover 7 so as to cut out the rectangular corner portion when the worker M1 performs maintenance of the machine body 3a. An opening 7a is formed in the work space A portion of the machine body cover 7 to allow the operator M1 to access the headstock 5 and the tool rest 6 when the machine body 3a performs maintenance or the like. The opening 7a is opened and closed by a machine body door 8 that is slidably arranged in the left and right directions.

The opening 7b is opened and closed by a setup door 9 arranged so as to be slidable up and down.
ここで作業者M2が前記段取りドア９を開閉する際に向き合う面、具体的には閉位置にある前記段取りドア９の外表面９ａは前記主軸台５の軸線５ａ′に対して４５°をなしている。従って、前記機械本体ドア８の外表面８ａと前記段取りドア９の外表面９ａの延長線は４５°の角度で斜めに交差している。 Here, the surface that the operator M2 faces when opening and closing the setup door 9, specifically, the outer surface 9 a of the setup door 9 in the closed position forms 45 ° with respect to the axis 5 a ′ of the headstock 5. ing. Accordingly, the extension line of the outer surface 8a of the machine body door 8 and the outer surface 9a of the setup door 9 crosses obliquely at an angle of 45 °.
このようにして前記加工ライン１は、各機械本体３ａを、前記各機械本体ドア８の外表面８ａが互いに平行をなし、また各段取りドア９の外表面９ａが同一直線上に位置するように配置することにより構成されている。 In this way, in the processing line 1, each machine body 3a is arranged so that the outer surface 8a of each machine body door 8 is parallel to each other and the outer surface 9a of each setup door 9 is located on the same straight line. It is comprised by arranging.
前記ワーク交換装置２は、前記機械本体３ａのベッド４上に旋回可能に支持された第１ワーク交換部１０と、該第１ワーク交換部１０に回動可能に支持された第２ワーク交換部１１とを有する。 The work changer 2 includes a first work changer 10 that is turnably supported on the bed 4 of the machine body 3a, and a second work changer that is turnably supported by the first work changer 10. 11.
前記第１ワーク交換部１０は、平面視でＬ字形状をなす第１アーム１２と、該第１アーム１２の横辺部１２ａの端部１２ａ′を前記Ｙ軸に平行な旋回軸ａ回りに水平方向に旋回可能に支持する軸受部１３と、該軸受部１３が固定された基板１４と、該基板１４に固定され、前記第１アーム１２を旋回駆動する駆動モータ２３とを有する。なお、前記基板１４は前記ベッド４に固定されている。また前記第１アーム１２の縦辺部１２ｂの端部１２ｂ′には軸支部１５が形成されている。 The first workpiece exchanging portion 10 has a first arm 12 having an L shape in plan view and an end 12a ′ of a lateral side portion 12a of the first arm 12 around a turning axis a parallel to the Y axis. It has a bearing portion 13 that is supported so as to be pivotable in the horizontal direction, a substrate 14 to which the bearing portion 13 is fixed, and a drive motor 23 that is fixed to the substrate 14 and that drives the first arm 12 to pivot. The substrate 14 is fixed to the bed 4. A shaft support portion 15 is formed at the end portion 12 b ′ of the vertical side portion 12 b of the first arm 12.
前記第１アーム１２は、前記主軸台５の軸線５ａ′と平行でかつ前記Ｙ軸と直交する第１平面（図５の紙面と平行な面）上において、前記縦辺部１２ｂが、前記軸線５ａ′に対して４５°をなす第１位置（図９（ａ）に示す位置）から、前記軸線５ａ′と一致する第２位置（図９（ｃ）に示す位置）へと移動可能となっている。 The first arm 12 is formed on a first plane parallel to the axis 5a ′ of the headstock 5 and perpendicular to the Y axis (a plane parallel to the paper surface of FIG. 5). It is possible to move from a first position (position shown in FIG. 9A) that forms 45 ° to 5a ′ to a second position (position shown in FIG. 9C) that coincides with the axis 5a ′. ing.
前記第２ワーク交換部１１は、前記第１アーム１２の軸支部１５に、前記第１平面と平行に配置された回動軸ｂ回りに垂直方向に回動可能に支持された第２アーム１６と、該第２アーム１６にワークを把持可能に配設された完成品ハンド１７及び素材ハンド１８と、前記第２アーム１６と前記基板１４とを連結する駆動ロッド１９とを有する。 The second work exchanging portion 11 is supported on the shaft support portion 15 of the first arm 12 so as to be pivotable in the vertical direction around the pivot shaft b disposed in parallel with the first plane. And a finished product hand 17 and a material hand 18 that are disposed on the second arm 16 so as to be able to grip a workpiece, and a drive rod 19 that connects the second arm 16 and the substrate 14.
前記第２アーム１６は、前記第１平面と直交し、かつ前記完成品ハンド１７及び素材ハンド１８の軸線同士を結ぶ直線１６ｂを含む第２平面上において、前記第１アーム１２の縦辺部１２ｂと平行の第３位置（図６，図９（ａ）に示す位置）から前記縦辺部１２ｂに直角の第４位置（図９（ｃ）に示す位置）へと移動可能に設けられている。 The second arm 16 is perpendicular to the first plane and includes a straight line 16b connecting the axes of the finished product hand 17 and the material hand 18 and the vertical side portion 12b of the first arm 12 on the second plane. Is movable to a fourth position (position shown in FIG. 9C) perpendicular to the vertical side portion 12b from a third position (position shown in FIGS. 6 and 9A) parallel to the vertical side 12b. .
前記完成品ハンド１７は前記第２アーム１６の上面に配設されたベース部１７ａと、該ベース部１７ａに、該ハンドの軸線と直角方向に移動可能に配設された３組の爪１７ｂとを有する。前記素材ハンド１８も同じ構造のベース部１８ａ，３組の爪１８ｂを有する。なお、前記ベース部１７ａ，１８ａは該ベース部の軸方向に付勢して設けられており、これによりワーク交換時のショックを緩和するようになっている。 The finished product hand 17 includes a base portion 17a disposed on the upper surface of the second arm 16, and three sets of claws 17b disposed on the base portion 17a so as to be movable in a direction perpendicular to the axis of the hand. Have The material hand 18 also has a base portion 18a having the same structure and three sets of claws 18b. The base portions 17a and 18a are provided to be urged in the axial direction of the base portion, so as to alleviate a shock at the time of workpiece replacement.
前記駆動ロッド１９は、前記第１ワーク交換部１０の前記第１平面上での移動に連動させて前記第２ワーク交換部１１を前記第２平面上で移動させるためのものである。前記駆動ロッド１９の一端部１９ａは前記第２アーム１６の先端から前記回動軸ｂを越えて突出する駆動アーム部１６ａにボールジョイント２０ａを介して連結軸ｄをなすように連結されている。また前記駆動ロッド１９の他端部１９ｂは前記基板１４の先端部１４ａにボールジョイント２０ｂを介して連結軸ｃをなすように連結されている。なお、１９ｃは前記駆動ロッド１９の長さを調節し、もって前記第２アーム１６の角度位置を調節する調節ねじである。 The drive rod 19 is for moving the second workpiece exchange unit 11 on the second plane in conjunction with the movement of the first workpiece exchange unit 10 on the first plane. One end portion 19a of the drive rod 19 is connected to a drive arm portion 16a projecting from the tip of the second arm 16 beyond the rotation axis b so as to form a connection axis d via a ball joint 20a. The other end 19b of the drive rod 19 is connected to the tip 14a of the substrate 14 via a ball joint 20b so as to form a connecting shaft c. Reference numeral 19c denotes an adjusting screw that adjusts the length of the drive rod 19 and thereby adjusts the angular position of the second arm 16.
ここで前記駆動アーム部１６ａとボールジョイント２０ａとの連結点ｄ′の、前記第１アーム１２の旋回軸ａ回りの前記軸線５ａ′に近づく方向Ｂにおける旋回軌跡Ｃ１と、前記連結点ｄ′の、前記駆動ロッド１９の連結点ｃ回りの前記方向Ｂにおける旋回軌跡Ｃ２とを比較すると、第１アーム１２の旋回角度が大きくなるほど大きなずれＤが生じる。 Here, the turning point C1 of the connecting point d 'between the drive arm portion 16a and the ball joint 20a in the direction B approaching the axis 5a' around the turning axis a of the first arm 12, and the connecting point d ' When the turning trajectory C2 in the direction B around the connection point c of the drive rod 19 is compared, a larger deviation D occurs as the turning angle of the first arm 12 increases.
その結果、第１アーム１２の旋回角度が大きくなるに従って、前記駆動ロッド１９が前記駆動アーム部１６ａを引っ張ることにより前記第２アーム１６を回動軸ｂ回りに回動させる。 As a result, as the turning angle of the first arm 12 increases, the drive rod 19 pulls the drive arm portion 16a to rotate the second arm 16 about the rotation axis b.
前記ずれＤは、前記駆動ロッド１９と基板１４との連結軸ｃを、前記旋回軸ａからの前記方向Ｂの反対側に偏位させている点、及び前記連結点ｄ′と前記連結軸ｃとの水平距離（半径）Ｒ２を前記連結点ｄ′と前記旋回軸ａの水平距離（半径）Ｒ１より短く設定している点に起因して生じる。即ち、前記偏位が大きくなるほど、また前記半径Ｒ２を半径Ｒ１より小さく設定するほど前記ずれＤは大きくなり、前記第１アーム１２の旋回に対して第２アーム１６が大きく回動する。本実施例では、前記偏位及び半径Ｒ１，Ｒ２を適宜設定することにより、前記第１アーム１２が４５°旋回する間に前記第２アーム１６が９０°回動するように構成されている。 The deviation D causes the connecting shaft c between the drive rod 19 and the substrate 14 to be displaced to the opposite side of the direction B from the turning shaft a, and the connecting point d ′ and the connecting shaft c. This occurs because the horizontal distance (radius) R2 is set shorter than the horizontal distance (radius) R1 between the connecting point d 'and the pivot axis a. That is, the deviation D increases as the deflection increases and the radius R2 is set to be smaller than the radius R1, and the second arm 16 rotates greatly with respect to the turning of the first arm 12. In this embodiment, the second arm 16 is rotated 90 ° while the first arm 12 is rotated 45 ° by appropriately setting the displacement and the radii R1, R2.
本実施例のタレット旋盤３では、機械加工中は、ワーク交換装置２は図９（ａ）又は図３に実線で示す段取り位置（第１位置）に位置しており、第１ワーク交換部１０の第１アーム１２が主軸５ａの軸線５ａ′に対して４５°をなしている。この状態で、作業者M2が段取りドア９を開けて完成品ハンド１７から加工済みワークW1を取り出すとともに、素材ハンド１８に未加工ワークW2をセットする。なお、この時点では、図３に示すように、段取り領域２２ｂと加工領域２２ａとは仕切りプレート２１で画成されており、機械加工中であっても安全にワークの搬入，搬出を行うことができる。 In the turret lathe 3 of this embodiment, during machining, the workpiece changer 2 is located at the set-up position (first position) indicated by the solid line in FIG. 9A or FIG. The first arm 12 forms 45 ° with respect to the axis 5a ′ of the main shaft 5a. In this state, the operator M2 opens the setup door 9 to take out the processed workpiece W1 from the finished product hand 17, and sets the unprocessed workpiece W2 in the material hand 18. At this time, as shown in FIG. 3, the setup area 22b and the machining area 22a are defined by the partition plate 21, and the workpiece can be safely carried in and out even during machining. it can.
前記機械加工が終了すると、前記仕切りプレート２１が待機位置に移動し、ワーク交換装置２の第１ワーク交換部１０の第１アーム１２が駆動モータ２３により旋回軸ａ回りに旋回駆動される。この旋回に伴って、前記駆動ロッド１９が前記ずれＤの分だけ前記第２ワーク交換部１１の第２アーム１６を回動させる（図９（ｂ）参照）。 When the machining is completed, the partition plate 21 is moved to the standby position, and the first arm 12 of the first work changing unit 10 of the work changing device 2 is driven to turn around the turning axis a by the drive motor 23. Along with this turning, the drive rod 19 rotates the second arm 16 of the second workpiece exchanging part 11 by the amount of the deviation D (see FIG. 9B).
前記第１アーム１２が４５°旋回されると、前記完成品ハンド１７及び素材ハンド１８が、前記主軸５のチャック５ｂに対向する位置、つまり加工済みワークを受取り可能で、未加工ワークを受け渡し可能の位置に移動する(図９（ｃ）参照)。この状態で、主軸５が、Ｚ軸方向及びＹ軸方向に移動し、チャック５ｂに保持されている加工済みワークW1が完成品ハンド１７に移載され、続いて素材ハンド１８に保持されている未加工ワークW2が前記主軸５のチャック５ｂに移載される。 When the first arm 12 is turned by 45 °, the finished product hand 17 and the material hand 18 can receive the processed workpieces at positions opposed to the chuck 5b of the spindle 5, that is, can deliver unprocessed workpieces. (See FIG. 9C). In this state, the main shaft 5 moves in the Z-axis direction and the Y-axis direction, and the processed workpiece W1 held by the chuck 5b is transferred to the finished product hand 17, and subsequently held by the material hand 18. The unprocessed workpiece W2 is transferred to the chuck 5b of the spindle 5.
このように本実施例装置では、第１ワーク交換部１０の第１アーム１２の第１位置から第２位置への移動と、第２ワーク交換部１１の第２アーム１６の第３位置から第４位置への移動とを連動させて、つまり第１位置から第２位置への移動と第３位置から第４位置への移動を同時進行的に行うようにしたので、段取り部２２ｂに搬入されたワークWを主軸５ａのチャック５ｂが保持可能の位置に短時間で移動させることができる。例えば従来装置のように、中立位置とワーク供給位置との間で前進又は後退させ、続いて前記中立位置とワーク渡し位置との間で回動させる場合はそれだけワーク交換に要する時間が長くなる。 As described above, in the present embodiment apparatus, the movement of the first arm 12 of the first workpiece exchange unit 10 from the first position to the second position and the third position of the second arm 16 of the second workpiece exchange unit 11 are changed from the third position. Since the movement to the fourth position is interlocked, that is, the movement from the first position to the second position and the movement from the third position to the fourth position are performed simultaneously, it is carried into the setup section 22b. The workpiece W can be moved to a position where the chuck 5b of the main spindle 5a can be held in a short time. For example, as in the case of the conventional apparatus, when advancing or retreating between the neutral position and the workpiece supply position and subsequently rotating between the neutral position and the workpiece transfer position, the time required for exchanging the workpiece is increased accordingly.
　また、機械本体３ａに第１ワーク交換部１０を設け、該第１ワーク交換部１０に第２ワーク交換部１１を設けたので、従来装置のように、ワーク搬入装置とワーク搬出装置を別個独立に設けた場合に比較して機械全体を小型化できる。 In addition, since the first work exchanging unit 10 is provided in the machine body 3a and the second work exchanging unit 11 is provided in the first work exchanging unit 10, the work loading device and the work unloading device are separated independently as in the conventional device. The entire machine can be downsized as compared with the case where it is provided.
　また、前記第１ワーク交換部１０の第１アーム１２は、ワークを保持して回転駆動する主軸５ａの軸線５ａ′を含む平面と平行な第１平面上で動作を行い、前記第２ワーク交換部１１の第２アーム１６は、前記第１平面に直交する第２平面上で動作を行うようにしたので、第１ワーク交換部１０の動作と第２ワーク交換部１１の動作とを、互いに干渉することなく連動させることができ、ワーク交換時間を確実に短縮できる。 The first arm 12 of the first workpiece exchanging section 10 operates on a first plane parallel to a plane including the axis 5a ′ of the main shaft 5a that holds and rotates the workpiece, and the second workpiece exchange Since the second arm 16 of the part 11 operates on a second plane orthogonal to the first plane, the operation of the first workpiece exchange unit 10 and the operation of the second workpiece exchange unit 11 can be performed mutually. The work can be linked without interference, and the work exchange time can be reliably shortened.
　さらにまた、作業者M1が機械本体３ａの主軸台５や刃物台６にアクセスするための機械本体ドア８を開閉する際に向き合う面、即ち該ドア８の外表面８ａと、作業者M2がワークを搬入，搬出するための段取りドア９を開閉する際に向き合う面、即ち該ドア９の外表面９ａとが斜めに交差するように前記機械本体ドア８及び段取りドア９を配置している。より具体的には、前記機械本体ドア８を主軸５ａの軸線５ａ′と平行に配置し、前記段取りドア９を前記軸線５ａ′に対して斜めに配置したので、機械本体ドア８の前に立って機械本体３ａにアクセスする作業者M1と、段取りドア９の前に立ってワークの段取り作業を行う作業者M2とが干渉するのを回避できる。従って機械本体３ａのメンテナンス中であってもワーク段取り作業を支障なく行うことができる。 Furthermore, the face facing when the operator M1 opens and closes the machine body door 8 for accessing the headstock 5 and the tool post 6 of the machine body 3a, that is, the outer surface 8a of the door 8, and the worker M2 The machine main body door 8 and the setup door 9 are arranged so that a surface facing when the setup door 9 for loading and unloading the door is opened and closed, that is, an outer surface 9a of the door 9 obliquely intersects. More specifically, the machine body door 8 is disposed in parallel with the axis 5a ′ of the main shaft 5a, and the setup door 9 is disposed obliquely with respect to the axis 5a ′. Thus, it is possible to avoid interference between the worker M1 who accesses the machine main body 3a and the worker M2 who stands in front of the setup door 9 and performs the work setup work. Therefore, even during the maintenance of the machine body 3a, the work setup work can be performed without any trouble.
　また機械本体ドア８と段取りドア９とを同一直線をなすように隣接配置した場合に比較して、一方のドアが他方のドアに対して斜めになっている分だけ機械全体の幅を小さくできる。 In addition, compared to the case where the machine body door 8 and the setup door 9 are arranged adjacent to each other so as to form the same straight line, the width of the entire machine can be reduced by the amount that one door is inclined with respect to the other door. .
　また、複数のタレット旋盤３，３・・を、作業者M1が機械本体ドア８を開閉する際に向き合う該ドアの外表面８ａが互いに平行で、かつ作業者M2が段取りドア９を開閉する際に向き合う該ドアの外表面９ａが同一直線上に位置するように配置したので、前記各タレット旋盤３，３の配置間隔を狭くしても作業者M1が機械本体ドア８の前に立って機械本体３ａにアクセスする場合に必要な作業スペースＡを確保し易い。従って必要な機械台数を確保しつつ、加工ライン長を短縮できる。 Further, when the operator M1 opens and closes the machine door 8, the door outer surfaces 8a facing each other when the operator M1 opens and closes the machine body door 8 are parallel to each other, and the operator M2 opens and closes the setup door 9. The outer surface 9a of the doors facing each other is arranged on the same straight line, so that even if the arrangement interval of the turret lathes 3 and 3 is reduced, the worker M1 stands in front of the machine body door 8 It is easy to secure a work space A necessary for accessing the main body 3a. Therefore, the processing line length can be shortened while ensuring the necessary number of machines.
　なお、前記実施例では、第１アーム１２の旋回角度が４５°であり、第２アーム１６の回動角度が９０°である場合を説明したが、本発明における旋回角度，回動角度の設定は任意であり、前記実施例に限定されない。 In the above embodiment, the case where the turning angle of the first arm 12 is 45 ° and the turning angle of the second arm 16 is 90 ° has been described. However, the setting of the turning angle and the turning angle in the present invention is described. Is arbitrary and is not limited to the above-described embodiment.
