The relay conveyor 5 is configured to move up and down. Furthermore, the above-mentioned guide 5a is provided with the positioning stopper 5k (refer FIG. 3 lower left) which engages with the lower end of the bracket 6c when the relay conveyor 5 is in the intermediate position mentioned above.

The positioning stopper 5k is configured to be detachable from the engagement with the bracket 6c when the relay conveyor 5 is lowered from the engagement position again.

Hereinafter, the operation of the present embodiment will be described.

1 to 3, the relay conveyor 5 is at the retreat level of the highest value, and the opening and closing door 6 integral with the relay conveyor 5 is in a state in which the first half of the work bench 2a is closed up and down. When the workpiece 3 is processed by a tool (not shown) installed on the spindle 2d, it functions as a safety cover, while fly ashes such as cutting powder generated at this time are blocked by the opening / closing door 6. As a result, no fly products adhere to the conveying conveyor 4.

Of course, since the relay conveyor 5 is also raised upward and insulated, fly products do not adhere as well.

When the processing of the workpiece 3 is finished, the workpiece 3 is released by the cylinder device 2g, and the drive means 5b is operated to lower the relay conveyor 5.

Then, the bracket 6c abuts on the positioning stopper 5k, and the relay conveyor 5 moves to the intermediate position of the two-dot chain line shown in FIG. Is controlled by In this state, the upper surface of the roller of the relay conveyor 5 coincides with the upper surface of the conveying conveyor 4, and is at a position slightly higher than the upper surface of the jig 7.

At this time, the door 6 is lowered to open the relay position. The workpiece 3 is transferred from the jig 7 onto the relay conveyor main body 5d of the relay conveyor 5, and then transferred forward, and then the conveying auxiliary conveyor 5c, the movable conveyor 4d and the downstream conveyor 4b. ) Is sent to the next step.

Subsequently, the workpiece 3 is carried in from the workpiece storage chamber 2e by the upper conveyor 4a movable conveyor 4d and the transport auxiliary conveyor 5c, and the relay conveyor body 5d in front of the work bench 2a. ) Is conveyed to the rear side, and after positioning on the jig 7, is fixed on the jig 7 by the cylinder device 2g.

The relay conveyor 5 is raised by the operation of the driving means 5b, the relay conveyor 5 is positioned at the highest value by the operation of the check switch 5f, and the opening and closing door 6 is closed. The same machining operation as described above is carried out.

A plurality of workpieces 3 of the same shape prepared on the workpiece storage chamber 2e are continuously and repeatedly processed in sequence by repeating the above-described operation.

On the other hand, when the shape of the workpiece 3 is changed and the jig 7 needs to be replaced, the positioning stopper 5k is pulled up so as not to fit with the bracket 6c and the movable conveyor 4b is removed. As shown by the dashed line on the 3rd degree, the driving means 5b is operated to raise the upper side so as not to interfere with the jig exchange, and the relay conveyor 5 is lowered until the third confirming switch 5h is operated. The position is determined by the jig 7 replacement level at the lowest position (see FIG. 1 dashed line).

At this time, the upper surface of the relay conveyor 5 is slightly higher than the upper surface of the work table 2a.

In addition, since the length of the leg 5e can be adjusted so that its lower end is in contact with the upper surface of the turntable 2b, it becomes a support when the heavy jig 7 is placed on the relay conveyor 5.

Further, the stopper 5i is inserted into the projection 5j to guide the jig 7 when transferring (see Fig. 4).

Then, the jig 7 on the work table 2a is removed, and the burner is placed on the relay conveyor 5 and returned to the jig storage chamber 2f, and the jig 7 of another shape is used to the work conveyor 2a. It is mounted on and fixed to the earth to complete the exchange of the earth (7).

In addition, in the present embodiment, the relay conveyor 5 combines the transport auxiliary conveyor 5c and the relay conveyor 5d with each other, but this may be used only as the relay conveyor main body 5d. In addition, the movable conveyor 4d may be slid in the lateral direction without being lifted up so as not to interfere with the replacement of the jig 7. In addition, the opening / closing door 6 may be integrally installed at a position other than the lower portion of the relay conveyor 5, and furthermore, the relay conveyor 5 moves up and down to retract from the work table 2a, and retracts from side to side. You may make it allow. In addition, an embodiment in which the workpiece 3 is transported in an integrally attached state to the jig 7 and replaced with the worktable 2a is also possible.

As in the above-described structure, the present invention is formed of the conveying conveyor 4 and the relay conveyor 5 sandwiched between the conveying conveyor 4 and the work table 2a at a relay position. When in the retracted position away from the worktable 2a, the relay position is closed by the opening / closing door 6, and when the relay conveyor 5 is in the loading / unloading position of the workpiece continuous to the worktable 2a, the relay position is Since the cutting powder protruding from the worktable 2a side at the time of processing is not attached to the relay conveyor 5 at the time of processing, not only the maintenance management of the equipment becomes easy, but also the stability is secured and the workpiece 3 is carried in. It also has the effect of improving the workability of exodus.

In addition, the driving source is sufficient as a single unit and can be formed as a simple device.
