Transfer bar 20 at the engaging position
The locking claws 3 are arranged at fixed positions so that they act in common.

On the other hand, the retaining members, that is, the engaging pins 10α, 10b are arranged in a position corresponding to the position of the bore H1 in the case of the transport block 8 for the large workpiece Wl at the clamp position for positioning the workpiece. A large diameter engagement pin 10α is located above. In addition, in the case of the conveyance block 8 for the hand workpiece W2, the small-diameter engagement pin AOb is located below the engagement pin 10α so as to fit in correspondence with the position of the bore 7, and moreover, the conveyance direction and the conveyance It is provided so as to be displaced in a direction perpendicular to the direction. In order to install the engagement pin 10h in the lower position, an auxiliary block 11 of a corresponding height is fixedly provided on the lower surface of the conveyance block 8 to correspond thereto.

Further, the common member 9 is provided with a plurality of workpiece type discrimination holes 19 at predetermined intervals, and a detection device in the enclosure inserts detection bins into the workpiece type discrimination holes 19 at the workpiece positioning clamp position. The type is determined based on the presence or absence of a hole, and a command to select the processing cycle of the processing device at that station and a shift command to the sub-knock bin 13 are issued, for example.

Further, in FIGS. 2 and 3, reference numeral 16 is a clamper that clamps the workpiece Wi on the transport rail 1 via the transport block 8, and 17 is a clamper that clamps the workpiece Wi on the transport rail 1 via the transport block 8, and 17 is a clamper that prevents the transport block 8 and the workpiece W from floating up during transport. for the top guide rail,
18 is a horizontal guide rail.

Note that the supporting position of the conveyor block 8 is not limited to the upper surface in the illustration, but it can also be mounted on the lower side, i.e., on the bearing caps of the four cylinder cylinders, when machining the upper surface of the workpiece. In some cases.

Further, in the above embodiment, two types of workpieces Wi, large and small, are transported, but the invention is not limited to this, and by preparing various types of transport blocks 8, the present invention can be applied to transporting workpieces W of various persimmons.

Since the present invention is configured as described above, first, by shifting the workpiece by a predetermined amount in a direction perpendicular to the conveyance direction at the conveyance position that is the previous process, it is possible to shift the workpiece by a predetermined amount in the direction perpendicular to the conveyance direction. Moso dowel hole 14.15α, 1
5b moves to a position where it is aligned with the dowel pins 12.13. In addition, at this loading position, the transport block 8 corresponding to the large workpiece W1 or the small workpiece W2 is automatically loaded and engaged with the pore H1 or the group.
Attach by engaging. After the transfer block is installed, the engaging claw 3 of the transfer bar 2 is engaged with the common member 9, and the transformer 7 cylinder 6 is operated to transfer the large workpiece v4 or the small workpiece W2 along the transfer rail 1 at a predetermined pitch. Then, it is transported to the processing station shown in FIGS. 2 and 3. At this machining station, the main knock 12 is inserted into the dowel hole 14 at one end, and the detection device detects the workpiece type discrimination hole. In the case of a senior, dowel hole 15b
The sub-knock bin 13 is shifted to correspond to K, and is engaged and positioned. Thereafter, it is clamped by the clamper 16, and the large workpiece W1 or the small workpiece W2 is processed by a circuit processing device. After the machining is completed, the clutch 5 is operated again to engage the engaging claw 3 of the transfer bar 2 with the common member 9, and the main knock bin 12 and the sub knock bin 13 are pulled out from the knock holes 14.15α or 15h, and the transformer 7 cylinder 6 is activated. The large workpiece W1 or the small workpiece W2 is transported along the transport rail 1 to the next processing station.

<Effects> As described above, according to the present invention, when conveying many types of workpieces with one transfer device, all that is required is for the engagement member to support the conveyance blocks corresponding to the workpieces. Since the engaging claws of the transformer 7 aber engage with the common members of all the transport blocks, setup changes can be made instantaneously, efficient transport can be achieved, and productivity can be improved. In addition, since the suppression clamp position of the auxiliary block attached to the workpiece and the guide position of the workpiece are common to various workpieces, the suppression flang device and guide rail can be used commonly for various workpieces. In addition, when a workpiece reversing device is installed in the transfer machine, the height dimensions of the workpiece including the transfer block are the same, so by gripping the upper and lower surfaces and reversing it, the workpiece reversing device can also be shared. It also has advantages.
