Above each of the plurality of work storage shelves 23, a skid 19 for mounting the work W or the product G is replaceably provided.

The skid 19 has the same structure as the skid 19 provided on the upper surface of the processing table 9 and the shuttle table 11 and has the same spacing between the skid pieces 19P, and the upper surface has a wavy width. A number of narrow skid pieces 19P that are narrow and elongated in the Y-axis direction are arranged and fixed in parallel in the X-axis direction at equal intervals above the work storage shelves 23 in each stage.

At the work transfer station ST1 provided on one side (the lower side in FIG. 1) of the carry-in / out station ST0 in the Y-axis direction, an appropriate work W is taken out from the work storage shelf 23 of the work storage device 21. To transfer onto the working table 9 or the shuttle table 11 by way of
In order to store the upper work W in the work storage shelf 23, an elevator device 33 is provided to be vertically movable.

More specifically, the elevator device 33 moves up and down while being guided by a vertical guide rail (not shown) provided on the support 29 of the work storage device 21. A chain (not shown) that moves around a sprocket (not shown) of a winch device (not shown) mounted on the upper portion of the device 21 and moves up and down is connected.

With the above configuration, the elevator device 33 is appropriately moved up and down by driving the winch device, and the elevator device 33 is moved to the height position corresponding to each work storage shelf 23 and the work table 9 or the shuttle table 11 with respect to the work W. Is positioned at a height where the feeding of the sheet is performed.

The elevator device 33 is not a cantilever type as in the above-described embodiment but a double-end type unless the installation location of the work loading / unloading device has no problem in terms of space or work inconvenience. It does not matter.

In the elevator device 33, for example, a traverser 35 as a work transfer device is provided so as to be able to reciprocate in the left-right direction (Y-axis direction) in FIG. 3, and as an example of a fork provided in the traverser 35. The work W is sent out and drawn into the work storage shelf 23 and the processing table 9 or the shuttle table 11 by the comb-like fork 37.

More specifically, when the elevator device 33 descends most, the large number of free bears 39 protrude upward from the interval between the multiple comb-shaped forks 37, so that the work W on the comb-shaped forks 37 is reduced to a large number of free bears 39. It is structured to be placed on top.

In the above configuration, first, the elevator device 33 is raised to the height of the work storage shelf 23 at an appropriate position, and when the traverser 35 advances, the comb-shaped fork 37 is moved to the desired unprocessed work. W is inserted into the space between the skid pieces 19P of the work storage shelf 23 on which the W is placed. The elevator device 33 rises slightly, and the work W on the skid 19 of the work storage shelf 23 is lifted by the comb-like fork 37. The traverser 35 retreats, and the desired work W is drawn into the elevator device 33.

The elevator device 33 descends to the height position of the skid 19 of the processing table 9 or the shuttle table 11 waiting at the loading / unloading station ST0.

After the traverser 35 retreats and the work W is hit against the locate pin 25, the elevator device 33 descends slightly. The work W on the comb-shaped fork 37 is placed on the skid 19 of the processing table 9 and clamped and positioned by the work clamp 27.

The traverser 35 of the elevator device 33 retreats, and the comb-shaped fork 37 is withdrawn from the space between the skid pieces 19P.

With the above arrangement, the locating pin 25 for positioning the work origin and the work clamp 27 for fixing the work W are provided on the processing table 9 and the shuttle table 11, respectively. W will be positioned. Therefore, in the machining table 9 and the shuttle table 11, the locate pin 25 and the work clamp 2

After the work W on the shuttle table 11 has been laser-processed by the laser processing machine 1, the shuttle table 11
Is moved from the processing area to the loading / unloading station ST0 in the X-axis direction, and at the same time, the processing table 9 is moved from the loading / unloading station ST0 to the processing area to be processed.
The upper workpiece W is laser-processed by the laser processing machine 1.

As described above, while one of the processing table 9 and the shuttle table 11 is being laser-processed in the processing area of the laser processing machine 1, the other of the processing table 9 and the shuttle table 11 is carried in and out. Station ST
At 0, the product G is carried out and the work W is carried in. Thus, while one operation is being performed, the other operation is in a standby state. For example, in the case of laser processing, it is possible to eliminate wasteful time in which a work cannot be carried in and out, so that a laser processing with a high yield can be performed. I can do it.

In the above-described embodiment, the work transfer table includes the work table 9 and the shuttle table 11, which are configured so that the work area of the laser processing machine 1 and the loading / unloading station ST0 can be reciprocated and exchanged. Alternatively, only the processing table 9 without the shuttle table 11 may be used.

Next, the product G on the shuttle table 11 that has been moved to the loading / unloading station ST0 is
In order to be stored in the shuttle table 3, the elevator device 33 is raised to the height of the skid 19 of the shuttle table 11. At this time, the height of the comb-shaped fork 37 is slightly lower than the height of the product G on the skid 19 of the shuttle table 11.

When the product G is stored in a predetermined position of the work storage shelf 23 in advance, the elevator device 33 is lowered to the lowermost position, so that a large number of free bears 39 are connected to a large number of comb-like forks 37. The work W on the comb-toothed fork 37 is placed on a large number of free bears 39.

After the product G is moved and positioned at a predetermined position, the elevator device 33 is raised by instructing a desired stage of the work storage shelf 23 to be stored, and the work storage shelf 23 as described above is moved up. The product G in the elevator device 33 is advanced by the traverser 35 and the comb-like fork 37 and stored on the skid 19 of the desired work storage shelf 23 in a reverse operation to the case where the work W is pulled out from the storage device 23.
The traverser 35 retreats and the storing operation is completed.

As described above, the plurality of comb-shaped forks 37 of the traverser 35 provided in the elevator device 33 move forward and backward without using a pallet, whereby the work W on the work storage shelf 23 is drawn out to the elevator device 33. The processed product G in the elevator device 33 is stored on the work storage shelf 23. Further, the plurality of comb-tooth-like forks 37 move forward and backward, so that the elevator device 3
The work W in 3 is placed on the work transfer table, and the processed product on the work transfer table is carried out into the elevator apparatus. Therefore, a pallet, which has been required in many cases in the past, is not required, so that the cost can be significantly reduced.

Further, since various devices for pulling in and positioning the pallets, which have been conventionally required, are not required, the cost can be reduced and the reliability can be improved.

Further, since the pallet is not damaged as in the prior art, the laser processing machine 1 can stably use the laser processing with high precision for a long period of time.

The present invention is not limited to the above-described embodiment, but can be embodied in other modes by making appropriate changes. In the present embodiment, a laser processing apparatus has been described as an example of a plate processing machine, but a plasma processing machine, a punch press, and other plate processing machines may be used.

In the embodiment described above, the work storage device 21 is provided above one end of the table base 13 on which the work transfer table such as the processing table 9 or the shuttle table 11 is provided so as to be able to travel. But
The position of the work storage device 21 is not limited to this. For example, the work storage device 21 can be provided adjacent to one side of the work transfer table. In this case, the traverser 35 of the elevator device 33 is located below the work storage device 21. The work may be provided to be able to travel to the carry-in / out station ST0, and the work may be carried on the W work transfer table.
