The other end side of the workpiece P is inserted between the second transport chuck claws 61 in the open state of the second transport chuck 60, and after the insertion, the second transport chuck claw 61 is closed, and the workpiece P is in the closed state. It is sandwiched and held between the pair of second transport chuck claws 61 as shown by the alternate long and short dash line, and is thus delivered from the first spindle chuck 40 to the second transport chuck 60 as shown by arrow 163. After this delivery, the first spindle chuck 40 is opened, and the first spindle unit 26 retracts in the direction opposite to the direction indicated by the arrow 162.

The opening movement of the second transport chuck claw 61 is performed by supplying a pressure fluid to the opening port 120 of the second opening / closing cylinder mechanism 117, and their closing movement is to supply the pressure fluid to the closed port 122. Is done by. Further, in this embodiment, the first and second transfer chucks 58 and 60 of the transfer unit 54 are configured to rotate at the same time and are held at the first angle position or the second angle position, as described above. When delivering from the first spindle chuck 40 to the second transfer chuck 60, the first and second transfer chucks 58 and 60 are held at, for example, the first angle position.

After that, although not shown, the transfer unit 54 moves somewhat to the left in FIG. 7 and is held by the first transfer chuck 58 (a pair of first transfer chuck claws 59) of the workpiece P (for example, unprocessed). The thing) is delivered. For example, the other end side of the workpiece P is held by the first transport chuck 58 (first transport chuck claw 59) of the transport unit 54, and one end side of the thus held workpiece P is the first spindle of the first spindle unit 26. It is delivered to the chuck 40 (first spindle chuck claw 41).

When the work piece P is delivered to the first spindle unit 26 side, the first spindle unit 26 is moved along the second support mechanism 24 in the direction indicated by the arrow 162 (the direction close to the transport unit 54) and is conveyed. One end side of the workpiece P held by the first transfer chuck 58 (a pair of first transfer chuck claws 59) on the unit 54 side is inserted between the first spindle chuck claws 41 in the open state of the first spindle chuck 40, and further. The first pusher 108 is activated to position the work piece P for insertion. That is, the first pressing cylinder mechanism 142 is extended, and the pressing member 144 acts on the other end of the workpiece P held by the first transport chuck 58 and presses it toward the first spindle unit 26 in this way. The work piece P is inserted to a predetermined position. After this insertion, the first pressing cylinder mechanism 142 contracts and the pressing member 144 retracts.

The insertion movement of the pressing member 144 is performed by supplying a pressure fluid to the extension port 154 of the first pressing cylinder mechanism 142, and the backward movement thereof is performed by supplying the pressure fluid to the contraction port 156.

When the workpiece P is inserted in this way, the first spindle chuck claw 41 is closed, and the workpiece P is sandwiched and held by the first spindle chuck 40 (a pair of first spindle chuck claws 41). In this way, it is delivered to the first spindle chuck 40, and after this delivery, the first spindle unit 26 retracts in the direction opposite to the direction indicated by the arrow 162. When the workpiece P (unprocessed) is delivered in this way, as shown in FIG. 8, the first transport chuck 58 of the transport unit 54 is in an empty state (a state in which the workpiece P is not held). become.

When the delivery of the workpiece P at the first delivery position is completed, as shown in FIGS. 8 and 9, the transport unit 54 moves from the first processing device unit 4 (first delivery position 54A) along the erection rail 52 with an arrow. It moves to the second processing apparatus unit 6 (second delivery position 54B) in the direction indicated by 164 (see FIG. 8), and the work piece P is delivered at this second delivery position.

In this embodiment, while moving from the first delivery position to the second delivery position, the first and second transfer units 58 and 60 are in the first angular position (FIG. 7), as can be seen from FIGS. 8 and 9. (Angle position shown in FIG. 9) turns in a predetermined direction (clockwise in FIG. 8) indicated by arrow 166, and is simultaneously turned to a second angle position (angle position shown in FIG. 9), and is controlled to rotate simultaneously in this way. This facilitates the turning control. The swivel movement of the first and second transport units 58 and 60 toward the second angular position is performed by supplying a pressure fluid to the first ports 128 and 132 of the first and second swivel cylinder mechanisms 124 and 126. Will be.

When the transport unit 54 moves from the first delivery position 54A to the second delivery position 54B in this way, as shown in FIG. 9, the workpiece P held by the second transport chuck 60 is in a state of being turned upside down and processed. The other end side of the object P (the side opposite to the one end side primary processed by the first processing device unit 4) faces the second processing device unit 6 (second spindle unit 26). When the work piece P is not inverted (when it is transported as it is), the first and second swivel cylinder mechanisms 124 and 126 do not operate, and the first and second transport chucks 58 and 60 do not operate. Is moved without flipping.

In this embodiment, while the transport unit 54 moves to the second delivery position 54B, the first and second transport units 58 and 60 are inverted and swiveled from the first angle position to the second angle position, so that the workpiece P is rotated. The configuration of the processing device can be simplified without the need for a dedicated reversing device for flipping the front and back. Further, the reversing step for reversing the workpiece by the reversing device as in the conventional case is not required, which makes it possible to shorten the machining time of the workpiece P and improve the efficiency of the machining efficiency. In addition, the time for moving from the first processing device unit 2 (first delivery position 54A) to the second processing device unit 6 (second delivery position 54B) while reversing is the same as the time for moving without reversing. In connection with this, processing in various steps becomes possible by using the first to third processing apparatus units 4 to 8.

The delivery of the work piece P at the second delivery position 54B is performed in the same manner as the delivery at the first delivery position 54A. First, the workpiece P is delivered between the second spindle unit 26 and the transport unit 54 of the second processing apparatus unit 6. For example, the other end side of the workpiece P is held by the second spindle chuck 40 of the second machining apparatus unit 6, and one end side of the thus held workpiece P is a machining tool attached to the second tool post unit 36 ( It is machined (for example, cut) by (not shown), and the machined work P (secondary machined) is delivered to, for example, the first transport chuck 58 of the transport unit 54, and the workpiece P is delivered. Delivery is performed in the same manner as described above.

When delivering the workpiece P, the second spindle unit 26 is moved along the second support mechanism 24 in a direction close to the transport unit 54, and one end side of the workpiece P held by the second spindle chuck 40 is moved. The first transfer chuck 58 is inserted between the open first transfer chuck claws 59, and after the insertion, the first transfer chuck claw 59 is closed, and the workpiece P is delivered to the first transfer chuck 58 in this way. Is done.

After that, although not shown, the transfer unit 54 moves slightly to the right and is positioned at the position shown in FIG. 9, and is held by the second transfer chuck 60 (a pair of second transfer chuck claws 61). Delivery of P (primarily processed by the first processing apparatus unit 4) is performed. One end side of the workpiece P is held by the second transport chuck 60 of the transport unit 54, and the other end side of the thus held workpiece P is the second spindle chuck 40 (second spindle chuck claw 41) of the second spindle unit 26. Will be delivered to.

When the work piece P is delivered to the second spindle unit 26 side, the second spindle unit 26 is moved along the second support mechanism 24 in the direction indicated by the arrow 168 (that is, the direction close to the transport unit 54). The other end of the workpiece P held by the second transfer chuck 60 on the transfer unit 54 side is inserted between the open second spindle chuck claws 41 of the second spindle chuck 40, and the second pusher 110 is further activated. The insertion position of the work piece P is performed. That is, the second pressing cylinder mechanism 150 extends, and the pressing member 152 acts on the other end of the workpiece P held by the first transport chuck 58 in the direction indicated by the arrow 170 to press the second spindle unit 26. Then, the workpiece P is inserted to a predetermined position in this way, and is thus delivered from the second transport chuck 60 to the second spindle chuck 40 as shown by the arrow 172.

In the above example, while moving from the first processing device unit 4 (first delivery position 54A) to the second processing device unit (second delivery position 54B), the first and second transfer chucks 58 and 60 are first. The workpiece P is inverted by turning 180 degrees from the angular position to the second angular position, but on the contrary, the first and second conveying chucks 58 and 60 move from the second angular position to the first angular position. The workpiece P may be inverted by turning 180 degrees.

Further, for example, in the above-described example, when the workpiece P held by the first transfer chuck 58 or the second transfer chuck 60 is inverted, the first and second transfer chucks 58 and 60 are simultaneously inverted and swiveled. The first transfer chuck 58 or the second transfer chuck 60 holding the workpiece P, although it is (turning from the first angle position to the second angle position or from the second angle position to the first angle position). Only may be inverted and swiveled.

Further, in the above-described example, the case of transporting from the first processing device unit 4 (first delivery position 54A) to the second processing device unit 6 (second delivery position 54B) has been described, but the first processing device unit 4 or The case of transporting from the second processing device unit 6 to the third processing device unit 8 (third delivery position 54C) can be performed in the same manner as described above. Further, in the case of transporting from the third processing device unit 8 to the second processing device unit 6 or the first processing device unit 2 in the opposite direction to the above-described transport direction, or from the second processing device unit 6 to the first processing device unit 2 It can be carried out in the same manner as described above in the case of transporting to.

Further, for example, in the above-described embodiment, the bed base 7 is provided with three processing device units (first to third processing device units 4 to 8), but the description is limited to such a configuration. However, the same can be applied to a bed base 7 provided with two or four or more processing apparatus units.

Although one embodiment of the processing apparatus according to the present invention has been described above, 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, it has been described by applying it to a bed base 7 to which a plurality of (for example, three) processing device units 4 to 8 are attached, but the present invention is not limited to such a device, and conventional work is performed. It can be similarly applied to a machine, for example, a conventional 2-spindle-2 slide type, a conventional 3-spindle-3 slide type, and the like.

For example, in a conventional 2-spindle-2 slide type processing device (for example, NC lathe), although not shown, the first spindle unit (or the first tool post unit) is placed on one side of the bed body installed on the floor surface. ) Is arranged, the second spindle unit (or the second tool post unit) is arranged on the other side, and in connection with such a configuration, the first spindle unit (or the first) is arranged on one side of the central portion of the bed body. The first turret unit (or the first spindle unit) is arranged corresponding to the turret unit), and the second spindle unit (or the second spindle unit) corresponds to the other side in the center of the bed body. A second tool post unit (or a second spindle unit) is arranged.

Objects are held detachably. Further, the first and second tool post units are equipped with first and second machining tools (for example, cutting tools) for machining the workpieces held by the first and second spindle chucks. The first and second machining areas are between the workpieces held by the first and second spindle chucks and the first and second machining tools attached to the first and second turret units. The work piece is processed in the second processing area.

In this case, the transport unit of the transport device is configured to transport the workpiece to the first and second spindle chucks, and the transport device can be configured in the same manner as described above. Generally speaking, the erection rail of the transfer device extends through the first and second processing areas, and the first and second transfer chucks are attached to the head portion of the transfer unit that moves while being supported by the erection rail, and these first and second transfer chucks are attached. 2 First and second pushers are provided on the head portion in connection with the transport chuck.

The first and second transfer chucks (first and second chuck bodies) have a first angle about the first and second swivel axes perpendicular to the first and second spindle axes of the first and second spindles. It is mounted on the head of the transport unit so that it can reverse and swivel between the position and the second angle position, and the transport unit of the transport device is the first machining area of the first spindle unit and the second machining area of the second spindle unit.
