Next, with reference to FIGS. 7 and 8, the transfer table 30 arrange|positioned below the turn table 1 is demonstrated. The transfer table 30 has a plurality of work accommodating portions 31 partitioned in a grid shape by a partition wall 32 .

In addition, the transfer table 30 is below the rotary table 1, and is movable on a horizontal plane in the X-Y direction. In this way, when the transfer table 30 moves on the horizontal plane in the XY direction, the workpiece W accommodated in the pocket 2 of the rotary table 1 and conveyed by the rotary table 1 is transferred to the suction nozzle. It is lowered by (22), and can be accommodated in the desired work storage part (31) of the transfer table (30).

Next, the effect|action of this embodiment which consists of such a structure is demonstrated.

First, as shown to FIG. 1 and FIG. 6A, the workpiece|work W, such as an apparatus component, is accommodated in the pocket 2 on the side of the workpiece|work feeder 11 among the rotary table 1 from the workpiece|work feeder 11. As shown in FIG. In this case, the rotary table 1 is stationary without rotating. In addition, the work W coming out of the work feeder 11 is supported by the loader base 13 at the connection portion between the work feeder 11 and the rotary table 1 and by the upper cover 12 . covered from above.

Next, the nozzle 25 of the suction nozzle 22 corresponding to the pocket 2 in which the workpiece W is accommodated among the suction nozzle apparatuses 20 installed above the rotary table 1 by the control unit 35 is It descends and enters the pocket (2), and when it enters slightly into the pocket (2), the nozzle (25) stops.

In this case, the resin plate 5 protrudes toward the inside of the pocket 2 in three sides of the upper end edge of the pocket 2 excluding the side on the outer periphery side of the rotary table 1 . For this reason, the upper end edge of the pocket 2 is sealed by the nozzle 25 and the resin plate 5. As shown in FIG.

Next, the suction unit 8 in the pocket 2 is actuated by the suction mechanism of the loader base 13 , and a flow of air is generated so as to draw the workpiece W in the pocket 2 . In this case, since the upper edge of the pocket 2 is sealed by the nozzle 25 and the resin plate 5 as described above, the inside of the pocket 2 can be effectively suctioned, and the pocket 2 It is possible to increase the state of internal suction.

In this way, after the inside of the pocket 2 is in the suction state, as shown in FIG. 6B , the work W coming out of the work feeder 11 is guided from the vertical direction by the upper cover 12 and the loader base 13 . and is drawn into the pocket 2 in the suction state.

Next, when the work W enters the pocket 2 , the work detection unit 9 detects that the work W enters the pocket 2 .

It reaches the position rotated by °. Thereafter, the rotation table 1 and the suction nozzle device 20 stop their rotation.

At this time, the nozzle 25 of the suction nozzle 22 which came to the position rotated by 180 degrees with respect to the work feeder 11 adsorb|sucks and holds the workpiece|work W in the pocket 2 in the lower end. Next, by the control part 35, the nozzle 25 of the adsorption|suction nozzle 22 descend|falls further, and the nozzle 25 penetrates the inside of the pocket 2 and descend|falls further. When the work W adsorbed to the lower end of the nozzle 25 reaches the work receiving portion 31 of the transfer table 30 , the control unit 35 stops the nozzle 25 from descending, and the nozzle The adsorption action of (25) is stopped.

In this way, the work W adsorbed to the lower end of the nozzle 25 is accurately transferred into the work receiving unit 31 of the transfer table 30 , and then, the control unit 35 controls the nozzle of the adsorption nozzle 22 . (25) is raised upwards.

In this way, the work W can be sequentially transferred into the work accommodating part 31 of the transfer table 30 by the suction nozzle 22 which has reached the position rotated by 180 degrees with respect to the work feeder 11 in this way. . In this case, the control unit 35 can move the transfer table 30 on a horizontal plane in the XY direction, whereby the work W is moved by the suction nozzle 22 to the desired work receiving unit of the transfer table 30 . (31) can be transferred sequentially.

Moreover, the adsorption|suction nozzle 22 in the position which the rotary table 1 rotated 270 degree|times exists in a standby state, without adsorb|sucking the workpiece|work W in particular.

By sequentially repeating such an action, the work W sent from the work feeder 11 can be sequentially transferred into the desired work storage unit 31 of the transfer table 30 . Thereafter, the transfer table 30 is sent to the next step, and in the next step, the work W is taken out from the inside of the transfer table 30, and the work W is subjected to a performance inspection or an external inspection. Thereafter, the work W judged to be a good product is used as a device component.

As described above, according to this embodiment, the work W sent from the work feeder 11 is correctly positioned in the pocket 2 of the rotary table 1 by the nozzle 25 of the suction nozzle 22 . It is adsorbed and can be reliably conveyed to a position rotated by 180 degrees with respect to the work feeder 11 . In addition, with respect to the workpiece W which has reached the position rotated by 180 degrees with respect to the workpiece feeder 11 , it is easy and simple only by lowering the nozzle 25 of the suction nozzle 22 . It can be accommodated in the desired work storage unit 31 .
