[0002]
[Prior art]
Generally, in a processing machine such as a laser substrate drilling machine, as shown in an example in FIG. 1, in order to prevent contamination and scratches at the time of processing a substrate or at the time of transport, a supply material such as a slip sheet is sandwiched between the supply materials. The supply work 8A stacked on the loader 10 side is positioned on the positioning table 12 and supplied to the processing table 32 of the processing machine main body 30, and the work after processing is discharged again with the interleaf sandwiched therebetween. On the side of the unloader 40 as a discharge work 8B. In the drawing, 14 is provided with a motor 18 for moving the supply table 16 up and down so that the height of the uppermost surface of the stacked supply works 8A is constant. The enabled supply stocker 20 sucks the work 8A placed on the supply teifle 16 of the supply stocker 14 by the suction device 24 moved up and down by the air cylinder 22, and the processing machine body 30 A supply-side moving motor shaft for transporting the workpiece to the XY stage 34 for moving the processing table 32 in the XY directions, and a vertically movable workpiece 50 on the processing table 32 by an air cylinder 52. A discharge-side moving motor shaft 64 for suctioning by the moved suction device 54 and transporting it to the unloader 40 has a weight on the discharge table 66. A motor 68 is provided for moving the position of the discharge table 66 up and down so that the height of the uppermost surface of the discharge work 8B to be placed is constant. It is a stocker.
[0003]
As another example of the work supply / discharge device, as shown in FIG. 2, upper and lower motor shafts 23 and 53 are provided instead of the air cylinders 22 and 52 in FIG. In some cases, the tables 16 and 66 are fixed and omitted. In this case, the stockers 14 and 64 may be of a cart type or a fixed type.
[0004]
In such a processing machine, when a cushioning material such as a slip sheet is inserted between the works in order to prevent the work surface from being damaged, the cushioning material put into the supply work 8A on the loader 10 side is replaced with the unloader 40. Insert it between the discharge workpieces 8B. Therefore, the processing machine needs to alternately transport the work and the slip sheet from the loader 10 to the unloader 40.
[0005]
Conventionally, as shown in FIG. 3, after processing on the XY stage 34 is completed (step 100), the processed work is taken out by the suction device 54 on the unloader 40 side (step 102) and stored in the discharge stocker 64. (Step 104) On the other hand, the interleaf is supplied onto the processing table 32 by the suction device 24 on the loader 10 side (Step 106), and the interleaf is changed over on the processing table 32 (Step 108). It was stored on the discharge stocker 64 by the device 54 (step 110). On the other hand, the supply work 8A from which the slip sheet has been removed in step 106 is taken out from the supply stocker 14 (step 112), supplied to the processing table 32 (step 114), and processed on the processing table 32 (step 116). Then, the slip sheet is taken out from the supply stocker 14 (step 118).
[0006]
[Problems to be solved by the invention]
As shown in FIG. 3, the processing tact consists of a handling time and a processing time. However, conventionally, since the slip sheet is relayed on the processing table 32, the handling time is long and the tact is long. Had.
[0007]
Also, in each of FIGS. 1 and 2, four motor shafts (18, 20, 50, 68 in FIG. 1, and 20, 23, 50, 53 in FIG. 2) are required, and the cost is high. Furthermore, since the positioning table 12 is arranged alongside the XY stage 34, the occupied area of the machine is large. In addition, since the motor shafts 20 and 50 for horizontal movement are separated and fixed to the housings of the loader 10 and the unloader 40, respectively, there is also a problem that the alignment of both is difficult.
[0008]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is possible to reduce the handling time and reduce the tact time by enabling the buffer material to be held and stored without relaying the processing table surface during processing. As an issue.
[0009]
[Means for Solving the Problems]
According to the present invention, the work placed on the loader side with the cushioning material interposed therebetween is positioned on the positioning table and supplied to the processing table, and the work after the processing is completed is again placed on the unloader side with the cushioning material interposed therebetween. In the work supply / discharge device of the processing machine for stacking on top, a horizontal motor shaft movable from the loader side to the unloader side is provided, and the buffer material is transferred from the loader side to the unloader side without relaying at the processing table during processing. The present invention has been made to solve the above-mentioned problem in a portable manner.
[0010]
Further, a pair of upper and lower air cylinders is provided on the horizontal motor shaft via a vertical motor shaft.
[0011]
Further, the occupation area can be reduced by displacing the positioning table and the processing table up and down and partially arranging them.
[0012]
In addition, the positioning table can be moved up and down so that the height of the supply workpiece can be increased while minimizing the increase in the height of the entire machine.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0014]
According to the first embodiment of the present invention, as shown in FIG. 4, a supply-side moving motor shaft and a discharging-side moving motor shaft are integrated into a loader 10 in a work supply / discharge device similar to the conventional example shown in FIG. , A horizontal motor shaft 70 movable to the unloader 40 side, and suction devices 24, 54 provided on a vertical motor shaft 72 movable on the horizontal motor shaft 70 via a pair of vertical air cylinders 74, 76. Further, the positioning table 12 and the processing table 32 are vertically displaced, partially overlapped and obliquely arranged.
[0015]
FIG. 5 shows the operation in the present embodiment. In the present embodiment, after the processing on the XY stage 34 is completed in step 200, the processed work is taken out of the processing table 34 by the suction device 54 as shown in FIG. As shown, the next work is supplied to the processing table 34 by the suction device 24. Then, in step 206, processing by a processing machine is performed.
[0016]
On the other hand, in parallel with this, in step 208, the processed work held in the suction device 54 is stored in the discharge stocker 64 as shown in FIG. 8, and in step 210, as shown in FIG. The interleaf is taken out from the supply stocker 14, and in step 212, as shown in FIGS. 10 and 11, the interleaf held in the adsorber 24 is held by the adsorber 54 on the positioning table 12, and in FIG. Similarly, the slip sheet is stored in the discharge stocker 64, and in step 216, the next work is taken out from the supply stocker 14 by the suction device 24 in the same manner as in FIG.
[0017]
According to the present embodiment, since the horizontal movement axes of the loader 10 and the unloader 40 are integrated, the holding of the slip sheet can be stored without relaying the processing table 32 during processing, and the handling time can be reduced. Takt can be reduced. The number of motor shafts may be two, 70 and 72, and the number of motor shafts is small. Therefore, the mechanical structure and the control device are simple and inexpensive. Further, since the positioning table 12 and the processing table 32 are vertically displaced and partially overlapped and arranged obliquely, the machine size can be reduced, the installation area is small, and the factory is not taken up. Further, since the horizontal motor shaft 70 can be fixed to the processing machine main body 30, the centering adjustment of the moving axes of the processing machine main body 30 and the loader 10 or the unloader 40 at the time of installation reassembly is unnecessary, and the installation time can be shortened.
[0018]
In the above embodiment, the positioning table 12 is fixed, but in this case, as shown in FIG. 12, when the suction device 24 suctions the last sheet of the supply work, the suction device 54 12, the stroke L of the upper and lower air cylinders 76, 74 is determined by this condition.
[0019]
When the interleaf holding function is added, as shown in FIG. 13, when the adsorber 54 sucks the interleaf on the positioning table 12, the adsorber 24 interferes with one of the uppermost sheets of the supply work. Since it must not be performed, the supply work overlapping height M1 is determined based on this condition. In the case where the slip sheet is not switched, the process as shown in FIG. 13 does not exist.
[0020]
On the other hand, as in the second embodiment shown in FIG. 14, by adding a vertical movement mechanism 80 to the positioning table 12, the supply work overlapping height can be reduced without extending the strokes of the upper and lower air cylinders 76 and 74. M2. At this time, since the stroke of the air cylinder does not increase, an increase in the height of the processing machine can be minimized.
[0021]
In the above embodiment, the present invention is applied to a laser substrate drilling machine, but the application of the present invention is not limited to this, and a drilling machine using a mechanical drill and other than drilling are used. It is apparent that the present invention can be similarly applied to a general processing machine that performs the above processing. Further, the type of the cushioning material is not limited to the slip sheet.
[0022]
【The invention's effect】
According to the present invention, it is possible to change and store the cushioning material without relaying the processing table surface during the processing, thereby reducing the handling time and the tact time.
