FIG. 2 is a cross-sectional view of a work shooter device provided with a dust collecting mechanism.

The work shooter device 45 is generally composed of a work supporting movable portion 1, an intermediate work supporting portion (not shown), and a work supporting and fixing portion.

The work supporting movable portion 1 is provided on the side of the turret punch portion 42, and a flat fan-shaped table 4 having an arc side equal to the diameter of the turret table 42a is provided on the upper surface.

A work support movable unit up-and-down mechanism 5 and a tilt mechanism 10 are provided below the work support movable unit 1.

The work supporting movable unit up-and-down mechanism 5 includes an up-and-down cylinder 6 and an up-and-down guide mechanism 8. The vertical guide mechanism 8 includes a bearing 8b and a slide plate 8c slidable with respect to a rail 8a provided on the turret punch section 42.

As a result, in the operation of the elevating cylinder 6, the work supporting movable unit 1 is moved up and down by the vertical guide mechanism 8 via the slide plate 8c.

Further, a tilt fulcrum is provided at the upper end of the vertical guide mechanism 8. The inclined fulcrum has a structure in which the upper end of the slide plate 8c and the end 4a of the table 4 are connected by a hinge 13.

The tilting mechanism 10 is composed of a tilting cylinder 10c in which a base end portion 10a thereof is pivotally supported by a fixture 9 provided so as to project from a slide plate 8c, and a tip end of a rod 10b is pivotally supported by a lower portion of the table 4. Therefore, the table 4 has the tilt cylinder 10
By the operation of c, as will be described later, the hinge 13 can be tilted by a predetermined angle about the axis.

These lifting cylinder 6, cylinder 7, and tilt cylinder 10c are
A driving force is applied by an air source (not shown), and the controller controls the driving.

The lifting cylinder 6 and the tilt cylinder 10c may be hydraulic cylinders or solenoids.

At the end of the table 4 and directly below the laser head 53, there is a suction port 14a of the dust collecting mechanism 55, and a suction port 14a.
A suction duct 14b is provided in the lower part.

The suction duct 14b is provided as a dust collecting path to a dust collector (not shown), and sucks dross generated during laser processing by the laser head 53. The dross is collected in the dross box 14e on the way of the dust collecting path.

Further, the suction duct 14c is cut in an inclined shape at a midway position, and the dividing surface 14c allows the table 4 described later to be tilted. In addition, the dividing surface 14c has a packing 1 made of an O-ring in the U groove.

[Advantages of the Invention] According to the present invention, the work supporting movable portion is provided with a vertical suction duct for sucking dross generated during processing, and this suction duct is provided in the lower portion fixed to the base portion. On the other hand, the upper part is fixed to the work supporting movable part, and the upper part and the lower part of these suction ducts are divided into two parts by the dividing surface which is cut while being inclined in the suction direction. Therefore, in the vertical direction orthogonal to the work supporting movable part. Even if a special mechanism is not provided in the suction duct portion provided, only the work supporting movable portion is tilted, and at the same time, the upper portion of the suction duct is tilted and the work after laser processing can be easily discharged with a simple structure. Also, when the work support movable part returns to the horizontal state for processing the workpiece, at the same time, the upper part of the suction duct moves and joins the lower part at the joint surface, and the suction duct tilts and returns to the work support movable part. Does not interfere.

In addition, by providing packing on the divided surface of the suction duct, the airtightness of the divided surface portion that contacts the lower suction duct can be increased when the upper suction duct returns, and the suction force of the dross by the dust collector can be reduced. There is no. Also, since the dividing surface has a shape inclined with respect to the suction direction,
Only the compression force between the upper and lower suction ducts acts on the packing, so that airtightness can be maintained for a long period of time, and unnecessary force is not generated when the suction duct is tilted, and the work supporting movable part operates. Can be done smoothly.

Further, by providing the dross box between the suction duct and the dust collector, the dross is not sucked toward the dust collector,
It can be accumulated in this dross box and the dross can be easily eliminated.

Further, if the work supporting movable part is configured to be able to move up and down by the vertical mechanism, the work supporting part can be positioned at the upper position during the laser processing to perform the laser processing on the work material, and the work is ejected while being inclined as described above. In addition, when the work piece is punched using the die provided on the turret of the turret punch press machine, the work support part is located at the lower position and retracted from the rotational direction of the turret. Therefore, it can be used for a laser turret punch press machine that processes a workpiece using a laser and a die.
