[0008] A workpiece exchange device 100 is installed inside the four pillars 10. This wa The arc exchange device 100 has a rectangular orbit 50 whose four corners are arcuate. . This orbit 50 is installed so that its longitudinal direction is orthogonal to the rail 11, Two pallets 24 are provided on the orbit 50. two pallets 24 When the center of one pallet is located at the midpoint of the short side of the orbit 50, the center of the other pallet The center of the seat is also located at the midpoint of the other short side, and at this time, the four pillars 10 The pallet 24 inside is located at the center of the four pillars 10. Ru.

[0009] As shown in detail in FIGS. 2 and 3, the workpiece exchange device 100 is erected on a base 26. It has an outer support stand 42 and an inner support stand 43, and an outer track is provided on the outer support stand 42. A stand 33a is placed, and an inner track stand 33b is placed on the inner support stand 43. . A sprocket wheel 53 is located at one of the four corners of the inner track 33b. It is rotatably supported on a rotation support shaft 14. Guide rollers 5 are in the other three corners. 2 is rotatably supported on a rotating support shaft 45, and these sprocket wheels 53 and A chain 46 is wound around the guide roller 52.

0010 The sprocket wheel 53 is driven by the gear 21a by the motor 20 having a speed reducer. , 21b, whereby the chain 46 is moved around. Two support wheels 55, which will be described later, are mounted on this chain 46. A mounting plate 22 for attachment is connected. The orbiting orbit 50 includes an outer orbit 50a and an inner orbit installed on the outer orbit platform 33a. It consists of an inner track 50b installed on a track platform 33b. On the inner track 33b An auxiliary rail 36 that auxiliary supports the pallet 24 is attached by a bracket 36a. It is fixed on the inner track 33b. This auxiliary rail 36 has a large number of guide rows. The pallet 24 is supported by the guide roller 37. It has become.

[0011] Two support wheels 55 are attached to the bottom of the pallet 24 at a predetermined interval. It is. The support vehicle 55 is a vehicle body attached to the pallet 24 via the fixing plate 54. 63, a set of wheels 64 provided on the side of the vehicle body 63, and a set of wheels 64 attached to the lower surface of the vehicle body 63. It consists of a rotating body 61 attached to the rotating body 61 and a connecting shaft 62 fixed to the lower surface of the rotating body 61. Ru. The vehicle body 63 is rotatable around the axis 02, and the support vehicle 55 can change direction. is facilitated. One of the two wheels 64 is connected to the outer track 50a and and is located on the inner track 50b. The rotating body 61 is connected to the axis 02 separately from the vehicle body 63. It can be rotated around the inner track 50b and moves along the side surface of the inner track 50b as a guide surface. It has become. The connecting shaft 62 is fixed to the mounting plate 22.

0012 Next, the operation will be explained based on the above-described configuration. Move the movable table 15, movable table 16, etc. The laser torch 18 is moved by brushing, and the laser torch 18 emits light. A workpiece (not shown) placed on the pallet 24 inside the support column 10 is fixed by the laser beam. It is processed into the shape of. During laser processing, the outer pallets 24 of the plurality of supports 10 are , remove the processed workpiece, and set the unprocessed workpiece. Processing is completed Then, the laser torch 18 rises to a predetermined position. In this state, the motor 20 is driven. When it moves, the chain wound around the sprocket wheel 53 and the guide roller 52 The ring 46 moves around, the mounting plate 22 moves accordingly, and the connection shaft 62 A support car 55 connected to the mounting plate 22 moves while supporting the pallet 24. child At this time, the rotating body 61 is guided to the side surface of the inner track 50b, and at the same time the wheel 64 is It moves on the orbit 50a and the inner orbit 50b. In addition, the pallet 24 is connected to the auxiliary rail 3 Since it is also supported by the guide roller 37 of 6, it can be stably shaped around the rectangle It can move in a circular orbit 50. Furthermore, the pallet 24 is located at the arcuate portions at the four corners of the orbit 50. Even if you approach the road, the vehicle body 63 can rotate around the axis 02, so the wheels 64 Since the direction can be changed in the direction of the applied force, the pallet 24 can be moved smoothly. It moves on the orbit 50.

[0013] Therefore, the distance on the short side of this rectangular orbit 50 is A pallet 24 on which a workpiece is placed and a pallet 24 on which an unprocessed workpiece is placed. It is sufficient that there is enough distance for pallets 24 to pass each other when exchanging, and Since it is not affected by the distance on the long side of the circular orbit 50, the distance between the supports 10 should be made sufficiently small. The entire laser processing machine can be made smaller.

[0014] In the embodiment described above, the orbit 50 is rectangular with four arcuate corners. An elliptical orbit 501 as shown in FIG. 4 may also be used. 241 in Figure 4 shows how the pallet 24 moves.

As described above, the working device equipped with the workpiece changing device of the present invention has an arcuate portion. The width of the workpiece changer crosses the pallet in order to move on a rectangular orbit. It is sufficient that there is enough distance for pallets to pass each other when exchanging workpieces. Since the width of the switching device is not affected by the depth of the orbit, the distance between the supports can be kept sufficiently small. It is possible to reduce the size of the entire working device.
