5.1 Station 1
The nozzle at Station 1 picks up parts from the tape set in the feeder. The
feeders, nozzles, and the twelve heads all combine to make pick-up
possible with the following operations.
• Tape feed-lever forward and backward
• Tape positioning claw up and down
• Push-up pin lever movement
• Tape-end detection
• Waste tape cutting
• Tape leaf sensor
• Nozzle up and down movement
• Nozzle valve movement

5.1.1 Tape Feed Lever Forward/Backward Stroke
The tape feed advance and retract stroke sends the tape forward.
The feeder moves the component to the pick-up position with the
forward stroke.
Square-motion type feeders however, advance the tape with the up
and down movement of the tape positioning claw, along with the
forward and backward motion of the tape feed lever.
• Drive Mechanism
The cam starts the tape feed cycle by advancing the lever on the
feeder. The stroke (fixed) depends on the cam curvature.

• Adjustment Method
Have the special jig and gage prepared beforehand.
Fig. 5-3 Station 1 Adjustment Jig
Note : This jig is also necessary for the tape-positioning claw
adjustment (Section 5.1.2), push-up pin adjustment (Section
5.1.3), and for the tape-end detection adjustments (Section
5.1.4).
1) Set the adjustment jig at D1 on the device table.
• Ensure that there are no obstructions on the base of the jig.
• Confirm that the jig will not interfere with station 1.
Note: It is possible to make the adjustments with the jig set at
positions other than D1.
2) Press [SET] → [POSITION] → [D AXIS] → (input device # 1) →
[CR] and [START] to move the adjustment jig to station 1.
3) Press the EMERGENCY STOP button to take the machine from
200 volts down to 100 volts.
4) Watch the cam graduation plate and rotate the cam to 0° with
the cam handle.
5) Press [SET] → [MANUAL] → [I/O] → [OUT] (use the +Page
and the s t keys to select “Y020 Pickup Sol ON”) and then
change the display from X to O with [ON/OFF] to release the
station 1 solenoid stopper.
• If the solenoid is not released, the adjustment cannot be
performed.
6) Use the cam handle to rotate the cam to 260°.
• The roller pushes the feeding lever to the advance-limit feeding
position when the cam is at 260°.
