As shown in FIGS. 14 and 15, the conventional blade driving apparatus has a structure in which a rotating shaft 3 having a single-type rotary blade 2 is installed inside a case 1, There is a disadvantage in that the rotating efficiency of the rotating shaft is very low because the rotating blade 2 can only contact once.

As shown in FIG. 15, when the compressed air flows into the interior of the case 1, passes through the single-type rotary vane 2, and reaches the end of the flow direction, the rotary vane does not exist, A reverse flow phenomenon of the rotating blades is generated, which causes a reduction in the rotating efficiency of the rotating blades and a decrease in the speed and thrust of the rotating shaft.

The first and second blade driving apparatuses 260 and 270 of the present invention are provided with a rotating shaft 264 having a plurality of continuous rotating blades 265 inside the case 261. In other words, When the compressed air introduced into the compressed air inlet 262 is discharged to the compressed air outlet 263 as the vanes 265 are continuously arranged from the position of the compressed air inlet 262 of the case 261 to the position of the discharge port 263 So that the rotation efficiency can be further improved.

The compressed air introduced into the compressed air inflow port 262 of the first and second blade driving devices 260 and 270 acts on the continuous rotation blades 265 until the compressed air is discharged to the compressed air discharge port 263, The ball screw 252 connected to the rotating shaft 264 rotates in place and then the conveyance plate 253 fastened to the ball screw 252 advances or retracts and is engaged with the conveyance plate 253 The transport block 212 of the first to fourth transporting jig units is rectilinearly transported and positionally adjusted.

At a position adjacent to the selected one of the first and second blade driving devices 260 and 270, a conveying block 253 is provided at a conveying position of the conveying plate 253, that is, 212) for detecting the feed position of the feed rollers (212, 212).

When the encoder 280 detects the transported position of the transport block 212, it is determined that the positional feed is completed, and the brake device operates to stop the rotation of the ball screw.

Preferably, the braking device 280 is installed between one side of the housing 251 and the first blade driving device 260 to provide a braking force when the ball screw 252 rotates.

Hereinafter, the construction and operation of the brake device will be described with reference to FIGS. 12 and 13. FIG.

A ball screw fixing shaft 281 is integrally formed with a rotating plate 282 and a ball screw 252 is connected to the ball screw fixing shaft 281. As shown in FIG.

The fixed brake pads 283 and the movable brake pads 284 are arranged with the rotation plate 282 interposed therebetween and the movable brake pads 284 are moved back and forth by the electromagnets to come into close contact with or separate from the rotary plate 282 .

As the means for providing the movable brake pad 284 with magnetic force for forward and backward movement, the electromagnet housing 285 is mounted while surrounding the ball screw fixing shaft 281 at a position adjacent to one surface of the movable brake pad 284 , And an electromagnet coil 286 is wound inside the electromagnet housing 285.

At this time, a guide rod 287 is integrally formed on the outer surface of the movable brake pad 284 and a guide groove 288 is formed on one surface of the electromagnet housing 285 so that the guide rod 287 is inserted and guided, The forward and backward straightness of the movable brake pad 284 can be ensured.

A plurality of springs 289 for pressing the movable brake pads 284 by elastic restoring force when the movable brake pads 284 are retracted are compressed on the one surface of the electromagnet housing 285 along the circumferential direction .

Therefore, when the power to the electromagnet coil is turned off at the time of braking, the movable brake pad 284 advances due to the elastic restoring force of the spring 289 and is brought into close contact with the rotating plate 282 as shown in FIG. 13 (b) The ball screw 282 is stopped and the ball screw 252 connected to the ball screw fixing shaft 281 of the rotation plate 282 is stopped.

On the other hand, when power is applied to the electromagnet coil at the time of non-operation of the brake, a magnetic force is generated as current is applied to the electromagnet coil 286, and the movable brake pad 284 compresses the spring 289, The rotary plate 282 connected to the rotary shaft 264 of the first or second brake driving device 260 or 270 is rotated while being separated from the rotary plate 282 as shown in FIG. The ball screw 252 connected to the ball screw fixing shaft 281 also rotates.

As described above, by combining the first to fourth transporting jig units, including the first and second fixed jig units, not only the vertical height of the transporting jig unit can be adjusted but also the position of the transporting jig unit can be adjusted linearly in the front, Any door panels (inner panel and outer panel) of different designs can also be commonly mounted for hemming.
