- the FOUP orbner and the transfer device are manually operated again, and the positions of the FOUP positioning grooves and the doc plate positioning pins are manually confirmed (step 507). Thereafter, until the shift between these two positions falls within a predetermined range, that is, the FOUP delivery position Steps 503, 506, and 507 are repeated until it is within the predetermined range.
- the stop position of the dock plate 31 is variable
- the FOUP 10 is temporarily attached, and then a transport device for transporting the FOUP 10 is temporarily put on standby above the F0UP orbner 1 (step 600).
- step 601 the position of the FOUP orbner 1 or the transfer device installed in step 600 is adjusted (step 601).
- the holding section of the transfer device holding the FOUP 10 is gradually moved to a position where the positions of the positioning groove 15 of the FOUP 10 and the positioning bin 32 of the dock plate 31 can be confirmed manually. Further, the dock plate 31 is moved to a position where the positions of the positioning groove 15 and the positioning pin 32 can be confirmed (Step 602).
- the dock plate 31 is manually operated again to move the FOUP 10 into contact with the positioning groove 15 of the FOUP 10. The adjustment is performed so that the positioning pins 32 substantially coincide with each other (step 606).
- the position data of the port 31 is input to the control means 60, and thereafter, the position data is stored in the storage section 61 (steps 61, 61).
- the position data of the dock plate 31 corresponding to each transfer device can be stored by managing the transfer device so that the transfer device can be managed by an identifiable identification number or the like.
- FIG. 13 shows an example of the detection sensor moving mechanism 400 shown in FIG. 5 (b) in which the ball screw 403 used in the detection sensor moving mechanism 400 is replaced by a cam mechanism.
