  Since this brace 44 supports the other end side (free end side) of the workpiece P held by the chuck means 18, it is configured as follows in relation to the main shaft (not shown) of the main shaft portion 12. Is done. That is, the center axis 20 of the main shaft (see FIG. 3) and the center axis of the workpiece P held by the anti-rest device 44 (specifically, three anti-vibration members 50) are configured to coincide with each other. Thereby, one end side of the long workpiece P can be stably supported by the chuck means 18 and the other end side can be stably supported by the brace 44.

  Next, the loader device 4 will be described. The illustrated loader device 4 includes a pair of support columns 62 and 64 installed on the floor of a factory, and the support columns 62 and 64 are arranged on both sides of the lathe body 6. The pair of support columns 62 and 64 may be attached to the lathe body 6.

  A hand support mechanism 66 for supporting a hand unit 78, which will be described later, is attached between the upper ends of the pair of support pillars 62 and 64. The hand support mechanism 66 moves the hand unit 78 in three dimensions. It is configured. The hand support mechanism 66 extends above the lathe body 6 in the lateral direction (the direction from the lower right to the upper right in FIG. 1, the direction perpendicular to the paper surface in FIGS. 2 and 5 and the left and right direction in FIG. 3). A main body 68 is provided, and both ends of the support rail main body 68 are fixed to a pair of support columns 62 and 64.

  A lateral movement member 72 is movably mounted on the support rail body 68 via first movement guide means (not shown), and the lateral movement member 72 is moved along the first movement guide means by a double-headed arrow 92 ( It is moved in the horizontal direction shown in FIG. Also, a laterally moving member 73 is mounted on the laterally moving member 72 through a second movement guide means (not shown) so as to be movable in the front-rear direction, and the front-back movement member 73 is along the second movement guide means. It is moved in the front-rear direction indicated by a double-headed arrow 96 (FIGS. 1, 2, and 5). Further, an elevating member 74 is movably mounted on the front end portion of the front / rear moving member 73 via third movement guide means (not shown), and the elevating member 74 is a double arrow along the third movement guide means. 94 (FIGS. 1, 2 and 5). Since it is configured in this way, the support rail main body 68, the lateral movement member 72, the front and rear movement member 73, the lifting member 74, and the like constitute the hand support mechanism 66.

  The hand unit 78 is attached to the tip (lower end) of the lifting member 74 of the hand support mechanism 66.

  Referring also to FIG. 4, the hand unit 78 includes a unit main body 82 attached to the elevating member 74, and the first hand chuck 84 and the second hand chuck 86 are attached to the unit main body 82 at an interval. ing. The first hand chuck 84 includes a pair of first chuck members 88, for example, an unprocessed workpiece P is held between the first chuck members 88, and the second hand chuck 86 is a pair of second chucks 88. A chuck member 90 is provided, and a processed workpiece P, for example, is held between the second chuck members 90 (see FIGS. 1 and 4). Contrary to the above, the processed workpiece P may be held in the first hand chuck 84 and the unprocessed workpiece P may be held in the second hand chuck 86.

  In relation to the structural wall 10 of the lathe body 6 and the first and second hand chucks 84 and 86 of the loader device 4, the construction is as follows. Referring mainly to FIG. 2, the structural wall portion 10 (specifically, the mounting support surface 22) of the lathe body 6 is configured to be inclined and extend rearward toward the upper side in the vertical direction. The angle α1 ((inclination angle α1 of the mounting support surface 22 with respect to the horizontal plane) (see FIG. 2) is preferably linearly inclined within an angle range of 45 to 75 degrees, for example.

  By tilting the structural wall portion 10 (mounting support surface 22) in this way, as shown in FIG. 2, the first turret structure 14 (its turret 30 and the like) and the second turret structure 16 (its turret 30 and the like) ) And the first and second turret structures 14 and 16 are inclined to the rear side, and the inclined arrangement angle α2 (see FIG. 2) is the structure. It becomes substantially equal to the inclination angle α1 of the wall 10 (α1 = α2). In this way, by tilting the structural wall portion 10 of the lathe body 6 (in other words, the first turret structure 14 is arranged on the upper side and the rear side with respect to the second turret structure 16), The space for the hand support mechanism 66 of the loader device 4 can be secured above the height, and the loader device 4, particularly the lifting member 74 and the hand unit 78, can be provided at the upper front side of the lathe body 6. Therefore, a movement space can be secured (see FIGS. 1 and 2).

  Referring mainly to FIG. 4, the first hand chuck 84 (the pair of first chuck members 88) of the hand unit 78 is vertically above the second hand chuck 86 (the pair of second chuck members 90). And it arrange | positions ahead in the front-back direction, and it is preferable that inclination | tilt angle (alpha) 3 to the back side of these 1st and 2nd hand chucks 84 and 86 inclines at 15-45 degree | times, for example.

  As described above, by arranging the first and second chuck hands 84 and 86 of the hand unit 78 in addition to the inclination of the structural wall portion 10 of the lathe body 6, the following operational effects are achieved. In the conventional lathe machining system, since the first and second hand chucks 84 and 86 are arranged in the front-rear direction at the same height position, the second hand chuck 86 is moved to the arrow 98 as estimated from FIG. If the workpiece P supported by the brace 44 is held by moving in the direction indicated by, a part of the first hand chuck 84 and a part of the brace 44 come into contact with each other. In order to avoid such interference, it is necessary to retract the brace 44 in the backward direction (in the direction of retreating from the main shaft portion 12). In contrast, in this lathe machining system, as shown in FIG. 5, the first hand chuck 84 is disposed above the second hand chuck 86, and therefore the second hand chuck 86 is moved to the arrow 98. The tip of the first chuck member 88 (front chuck member 88) of the first hand chuck 84 is moved as indicated by the alternate long and short dash line 100 even if it is moved in the direction indicated by. It is possible to hold the workpiece P without interfering with a part and without retracting the brace 44 to the rear side.

  Next, replacement of the workpiece P in the lathe processing system described above is performed, for example, as follows. Referring mainly to FIGS. 1, 2 and 5, in order to replace the workpiece P, for example, the unprocessed workpiece P is held on the first hand chuck 84 of the hand unit 78 (at this time, the second hand The chuck 86 does not hold the workpiece P). In this state, the lateral movement member 72 is moved laterally via first movement guide means (not shown), and the longitudinal movement member 73 is second. It is moved in the front-rear direction via a movement guide means (not shown), and the elevating member 74 is further moved downward via a third movement guide means (not shown). When the workpiece P held by the anti-vibration member 50 of the anti-vibration tool 44 is held by the second hand chuck 86 of the hand unit 78, the hand unit 78 is indicated by an arrow 98 with a downward and rear combined movement. The second hand chuck 86 of the hand unit 78 holds the processed workpiece P by being moved in this direction.

  When the processed workpiece P is held by the hand unit 78 (second hand chuck 86) in this way, the holding by the cleat 44 is released, and the holding by the chuck means 18 is released. The finished workpiece P can be removed.

  Thereafter, the hand support mechanism 66 moves the hand unit 78 as required, and the unprocessed workpiece P held by the first hand chuck 84 of the hand unit 78 is inserted and held in the chuck means 18 on the lathe body 6 side. At the same time, after being held by the brace 44 and being held in this way, the holding of the first hand chuck 86 of the hand unit 78 is released, and the unprocessed workpiece P is thus removed from the hand unit 78. After moving from the first hand chuck 84 to the chuck means 18 on the lathe body 6 side and removing the processed workpiece P, the unprocessed workpiece P is attached to the chuck means 18.

  In this way, the workpiece P is replaced, and the workpiece P held on the lathe body 6 side chuck means 18 and the cleat 44 is processed. Further, the lifting member 74 is moved upward, and the hand unit 78 holding the processed workpiece P is moved upward via the lifting member 74, and then the backward movement and lateral movement member 72 of the forward / backward moving member 73 is moved. , The processed workpiece P held by the hand unit 78 (second hand chuck 86) is transferred to the next processing step.

  As mentioned above, although one embodiment of the lathe processing system according to the present invention has been described, the present invention is not limited to such an embodiment, and various changes or modifications can be made without departing from the scope of the present invention.

  For example, in the above-described embodiment, the work support mechanism 42 includes the anti-rest tool 44 including the three anti-vibration members 50. The work support means 42 supports the tip of the work piece. A stand may be used.
