In the work shooter, a plurality of free bearings are arranged on the work shooter in order to make it easy to carry out the work or the scrap material, and to make it easy to carry in and move the work when the work shooter is horizontal. I have.

(Problems to be Solved by the Invention) In the above-described conventional work shooter, the upper surface of the free bearing protrudes from the upper surface of the shooter table of the work shooter. Therefore, when unloading the cut work or scrap material, when the work or scrap material is small, the work or scrap material is caught by the protruding portion of the free bearing, and the uncertainty of unloading is low. There was a problem that it could not be achieved.

An object of the present invention is to eliminate the protrusions on the surface of the shooter table only at the time of unloading the work, in order to improve the above problem,
An object of the present invention is to provide a work shooter of a processing machine which is smoothed to improve the reliability of unloading.

[Structure of the Invention] (Means for Solving the Problems) In view of the above-described conventional problems, the present invention provides a method for mounting a work on a top surface of a shooter base that can be freely tilted from a horizontal state supporting a work to an inclined state in which a tip side descends. A plurality of free bearings supporting the work are appropriately arranged and provided, and an upper limit of a shooter table movably provided on the upper surface of the shooter base is provided so as to be freely adjustable. In this configuration, the top of the free bearing and the upper surface of the shooter table are substantially at the same height.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 4 conceptually illustrates the entire configuration of a work shooter of, for example, a laser processing machine as a processing machine. A part of a work table 3 (partially omitted) of the laser processing machine 1 is tiltable. Work shooter 5 is provided.

The work shooter 5 includes, for example, a square-shaped dust collecting pipe 9 which is opened immediately below a processing head 7 (partly not shown) of the laser processing machine 1.
And is vertically provided on the lower surface of the processing portion pedestal 11.

The lower end of the dust collection pipe 9 is mounted on the base 13 of the laser beam machine 1.
The scrap box 17 is inserted into an outer frame 15 provided at a lower part of the outer frame 15 so as to be freely inserted and removed. Further, a suction device 23 is provided through a suction duct 21 through a scrap box insertion portion 19, which is sealed in a part of the base 13 by the outer frame 15, and sucks dust and the like generated during processing to remove the outside of the machine. Exhaust to

The work shooter 5 is provided with a rotatable link 29 via a pin 27 on a bracket 25 erected on the base 13, and one end of the link 29 is attached to a bracket 33 suspended from the work shooter 5 via a pin 31. It is rotatably connected. Further, the tip side of the work shooter 5 (the left side in FIG. 4)
A piston rod 39 of a fluid pressure operated cylinder 37 is rotatably engaged with a bracket 35 vertically provided on a lower surface of the work shooter 5, and the work shooter 5 can be tilted by the operation of the cylinder 37.

With the above configuration, the operation is performed by operating the cylinder 37 so that the work shooter 5 is held at a position corresponding to the pass line indicated by the line AA at the ascending limit of the cylinder 37, and is placed on the work shooter 5 and The processing of W is performed.

A predetermined cutting process is performed on the workpiece W, and the cylinder 37 is lowered when the processing is completed.

The work shooter 5 includes a pin 27 serving as a first fulcrum X and a second
The pin 31 and the link 29, which are the fulcrum Y, descend slightly in parallel by a small amount, and as the descent proceeds, tilt about the first fulcrum X and stop at the position B shown in FIG. By this tilt, the processed work is discharged out of the machine, and the above operation is performed in reverse to return the work shooter 5 to the original horizontal position, and shift to the next processing step.

Along with the movement of the work shooter 5 described above, the dust collecting pipe 9 fixed to the work shooter 5 moves to the position C shown in FIG. At this time, the lid 41 which is a part of the outer frame 15 is opened by being pushed by the tip of the dust collecting pipe 9 with the shaft 45 of the bearing 43 provided on the outer wall of the outer frame 15 as a pivot point. Since the lid 41 is normally urged in the closing direction by the spring 47, when the work shooter 5 returns to the horizontal state, the lid 41 also returns to the original position. At this time, the joint between the lid 41 and the outer frame 15 is not shown so as to be dense, but it goes without saying that a seal member or the like is provided.

Reference numeral 49 denotes a free bearing, which serves to smooth the movement of the work W, and a carbon graphite material 51 is laid under the scrap box 17. In the carbon graphite material 51, the laser beam emitted from the processing head 7 is
Although the bottom of 17 may be directly irradiated, the carbon graphite material 51 is provided at this portion, so that the scrap box 17 is not damaged by the laser beam and serves to prevent damage.

The work shooter 5 will be described in more detail. Referring to FIGS. 1 and 2, a plurality of free bearings 49 are provided on a shooter base 53 of the work shooter 5.
The processing unit base 11 is provided immediately below the processing head 7.

A shooter table 55 is provided above the shooter base 53.
Are provided so as to be able to move up and down via a link device 57.
A bearing 63 provided on the shooter base 53 is provided with a link 63 having a rotatably engaged shaft 61 which forms a part of the link device 57. A source, for example, a cylinder or a motor, or a motion mechanism in which the work shooter 5 moves up and down is linked by a link or the like.

The other end of the link 63 is rotatably engaged with a bearing 65 provided on the lower surface of the shooter table 55 via a pin 67, and a spring 69 is mounted between the shooter base 53 and the shooter table 55. ing. The repulsive force of the spring 69 constantly urges the shooter table 55 so as to push it upward. Further, as shown in FIG. 2, the shooter base 53 is provided with an inverted L-shaped table retainer 73 which is in contact with the bottom plate 71 of the shooter table 55 on both sides in order to determine the limit of ascent of the shooter table 55. In the above configuration, when unloading the cut workpiece W or scrap material, the work shooter 5 is lowered in a slightly parallel state and then tilted to be unloaded.

When the work shooter 5 moves in parallel, the shaft 61 is rotated by a drive source (not shown) together with the movement. When the shaft 61 rotates, the shooter table 55 moves up to the position shown by the two-dot chain line in FIG. 1 together with the repulsive force of the spring 69 via the link 63 provided integrally with the shaft 61, and
Stops ascent by contacting 73.

The upper surface of the free bearing 49 is set so as to be hidden at the position where the shooter table 55 is raised, so that even when the work shooter 5 is tilted even with a small work W or scrap material, it can be smoothly carried out without being caught by the free bearing 49. Can do it. During the loading and moving of the work W or during the laser processing, the shooter table 555 is used.
Is provided at a lowered position.

Further, the shooter table 55 rises with a circular arc drawn by the link motion of the link device 57, and the shooter table 55 moves as shown in FIG.
Move in the direction. Thus, since the distance L1 between the shooter table 55 and the processing portion base 11 is very small, even a small work W or scrap material can be carried out without being caught. As shown in FIG. 3, for example, if the shooter table 55 moves vertically up and down, the distance L2 between the shooter table 55 and the processing section pedestal 11 becomes large, and a small work W or offcuts is drawn between them. This causes inconvenience in hanging out.
This inconvenience has been eliminated in this embodiment.

As described above, when unloading the processed work W or scraps, the shooter table 55 is raised to hide the upper surface of the free bearing 49, so that even small workpieces W or scraps are caught by the free bearing 49 when unloading. Without this, the unloading process can be performed smoothly and reliably. Therefore, there is no trouble at the time of unloading, no extra labor is required, labor saving and improvement of productivity are achieved, and further, machine automation can be achieved.

The present invention is not limited to the above-described embodiment, but can be embodied in other modes by making appropriate changes. For example, although a laser processing machine has been described as an example of a processing machine, the present invention can also be used for a plate processing machine such as a plasma processing machine or a punch press.

[Effects of the Invention] As can be understood from the above description of the embodiments, in short, the present invention provides a shooter base (53) that can freely tilt from a horizontal state supporting a work (W) to an inclined state in which the tip side descends. A plurality of free bearings (49) supporting the work (W) are appropriately arranged and provided on the upper surface, and the ascending limit of a shooter table (55) movably provided on the upper surface of the shooter base (53) is limited. The top of the free bearing (49) and the upper surface of the shooter table (55) are substantially the same height at the limit of the ascent of the shooter table (55).

As is apparent from the above configuration, in the present invention, a plurality of free bearings 49 supporting the work W are appropriately arranged on the upper surface of the shooter base 53 which can be freely tilted. Further, the shooter table 55 is provided so as to be able to move up and down, and the limit of rise is provided freely. In the upper limit of the shooter table 55, the upper surface of the shooter table 55 and the top of the free bearing 49 substantially coincide with each other.

Therefore, according to the present invention, the work W to be machined can be supported by the free bearing 49 by lowering the shooter table 55 to make the free bearing 49 protrude, and The movement can be performed smoothly and smoothly. When the shooter base 53 is tilted and the carry-out product is dropped and conveyed, the shooter table 55 is lifted to restrict the product and the scraps cut and separated from the work W to the upper limit position. Since the height of the top of 49 is almost the same, even if the product is small, it does not abut on the free bearing 49 to prevent dropping and unloading. Is what you can do.
