There was a problem that it could not be planned.

The purpose of this invention is to eliminate protrusions on the surface of the shooter table only when unloading a workpiece, in order to improve the problem described in E.
An object of the present invention is to provide a workpiece for a processing machine which is smoothed and has improved reliability of unloading.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a workpiece processing section of a processing machine with a free bearing on the upper surface that can freely support the workpiece or scrap material after cutting. A work shooter is installed.
The work shooter is provided so that it can be moved up and down in a horizontal state and can be moved up and down in a tilted state, and the work shooter is provided with a shooter table that can be raised and lowered by the rotation of a link device together with the up and down movement of the work shooter. was constructed.

(Function) By employing the work shoe of the processing machine of the present invention, when carrying out a processed workpiece or scrap material, the work shooter is tilted after the shooter table is raised.

As the chute table rises, the upper surface of the free bearing installed in the work chute is hidden, and there is no protrusion on the surface of the chute table, making it possible to smoothly transport small workpieces or scraps without getting caught during transport. It becomes possible.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 4 conceptually illustrates the overall structure of a work shooter of a laser processing machine as a processing machine, for example, and a part of the work table 3 (partially not shown) of the laser processing machine 1 has a A tiltable work shooter 5 is provided.

In this work shooter 5, a dust collection vibrator 9, which has a rectangular shape and is opened upward and is located directly below the processing head 7 (partially not shown) of the laser processing machine 1, is attached to a processing part pedestal provided in the work shooter 5. It is installed vertically on the bottom surface of 11.

The lower end of the dust collecting pipe 9 is connected to the base 13 of the laser processing machine 1.
The scrap box 17 is inserted into an outer frame 15 provided at the bottom of the outer frame 15, and a scrap box 17 is provided at the lower part of the outer frame 15 so as to be freely put in and taken out. Furthermore, a suction device IF 23 is installed through a suction duct 21 that passes through a scrap box insertion part 19 sealed in a part of the base 13 by the outer frame 15, and sucks out dust generated during processing and removes it from the machine. Exhaust to.

In the work shooter 5, a rotatable link 29 is provided on a bracket 25 erected on a base 13 through a pin 27, and one end of the link 29 is connected to a bracket 33 vertically installed on the work shooter 5 through a pin 31. Connected for free rotation. Furthermore, a piston rod 39 of a hydraulically operated cylinder 37 is rotatably engaged with a bracket 35 that is vertically installed on the lower surface of the tip side (the left side in FIG. 4) of the work shooter 5. The work shooter 5 can be tilted freely.

With the above configuration, the operation is as follows: By operating the cylinder 37, the work shooter 5 is held at a position corresponding to the bus line indicated by line A-A at the upper limit of the cylinder 37, and the workpiece is placed on the work shooter 5. W processing is performed.

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

The work shooter 5 is connected to the bin 27 which is the first fulcrum X and the second
The pin 31 and the link 29, which are the fulcrum Y, are used to lower the robot in a slightly rigid and almost parallel manner, and as the descent progresses, it tilts around the first fulcrum X and stops at the 8 position shown in FIG. This tilting causes the processed workpiece to be ejected from the machine, and by reversing the above-described operation, the workpiece shooter 5 is returned to its original horizontal position, and the next processing step is started.

Along with the movement of the work shooter 5 described above, the dust collection vibrator 9 fixed to the work shooter 5 moves to the C position shown in FIG. 4. At this time, M41, which is a part of the outer frame 15, is the shaft 45 of the bearing 43 provided on the outer wall of the outer frame 15.
is used as a rotational fulcrum and is pushed by the tip of the collection pipe 9 to open. Since the N41 is always 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 its original position w9I. At this time, although the joint between the fl 41 and the outer frame 15 is omitted from illustration to ensure a tight connection, it goes without saying that a sealing member or the like is provided.

Incidentally, reference numeral 49 denotes a free bearing, which serves to smooth the movement of the workpiece W, and a carbon graphite material 51 is laid in the lower part of the scrap box 17. The carbon graphite material 51 may be directly illuminated by the laser beam irradiated from the processing head 7 onto the bottom of the scrap box 17. is not damaged by the laser beam and serves to prevent damage.

The work shooter 5 will be explained in more detail.

Referring to FIGS. 1 and 2, there are a plurality of free bearings 49 on the shooter base 53 of the work shooter 5.
is arranged, and a processing part pedestal 1 is placed directly under the head 7.
1 is provided.

Above the shooter base 53 is a shooter table 5.
5 is provided so as to be freely movable up and down via a link device 57. The bearing 59 provided on the shooter base 53 is provided with a link 63 that is a part of the link device 57 and has a rotatably engaged shaft 61. Although not shown, the shaft 61 is rotatably driven. The source, for example, a cylinder or motor, or the work shooter 5 is linked by a link or the like to a movement mechanism that moves up and down.

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, so that the shooter base 53 and the shooter table 55 are connected to each other.
Six springs are attached to rg1. The elastic force of the spring 69 constantly urges the shooter table 55 upward. Furthermore, as shown in FIG. 2, the shooter base 53 is provided with an inverted L-shaped table holder 7 that comes into contact with the bottom plate 71 of the shooter table 55 in order to determine the upper limit of the shooter table 55.
In the above structure in which the cutter 3 is provided on both sides, when carrying out the workpiece W or offcuts that have been cut, the workpiece chute 5 is lowered in a parallel state by a certain amount, and then is tilted and carried out.

When the work shooter 5 moves in parallel, the shaft 61 is rotated by a drive source (not shown) along with the movement. When the shaft 61 rotates, the shooter table 55 moves upwardly to the position shown by the two-dot chain line in FIG. It touches and stops rising.

The upper surface of the free bearing 49 is hidden when the chute table 55 is raised, so that even when the work chute 5 is tilted, even a small workpiece W or scrap material can be moved smoothly without being pulled against the free bearing 49. Can be carried out. In addition, when carrying in the workpiece W,
During movement or laser processing, the shooter table 55 is provided in a lowered position.

Further, due to the link motion of the link device 57, the shooter table 55 moves upward in a circular arc and moves in eight directions shown in FIG. Since the distance 1 between the shooter table 55 and the processing unit pedestal 11 is minute, even small workpieces W or scraps can be carried out without getting caught. Note that, as shown in FIG. 3, for example, if the shooter table 55 moves up and down vertically, the distance L2 between the shooter table 55 and the processing section pedestal 11 will be large.
During this time, small workpieces W or offcuts may get caught, causing inconvenience in carrying out. This inconvenience has been solved in this embodiment.

As mentioned above, when carrying out the processed workpiece W or offcuts, the shooter table 55 is raised to hide the top surface of the free bearing 49, so even small workpieces W or offcuts can be caught on the free bearing 49 when carried out. You can carry out the unloading process smoothly and reliably without any problems. Then,
There are no troubles during transport, no extra manpower is required, labor is saved and productivity is improved, and machines can be automated.

Note that the present invention is not limited to the embodiments described above, but can be implemented in other embodiments by making appropriate changes. For example, although a Rege processing machine has been described as an example of a processing machine, it can also be used for plate processing machines such as a plasma processing machine and a punch press.

[Effects of the Invention] As can be understood from the description of the embodiments described above, according to the present invention, when carrying out a cut workpiece or end piece, the shutter table provided in the workshooter is connected to the link device. Since the upper surface of the free bearing is hidden by the upper surface of the free bearing, the work or scraps can be carried out smoothly without being crushed by the free bearing. Therefore, there is no trouble during transport, and no extra manpower is required, making it possible to save labor and improve productivity.
