B Excessive parts tape feed errors

B-1 Does the part’s tape feed pitch match the feeder specification?

Check whether the part’s tape feed pitch matches the feeder specification.

B-2 Is the rotation torque of the reel in the holder within specification?

(for W8 mm tape 13-inch parts reels)

Set the rotation torque measurement reel into the reel holder and measure the

rotation torque with a push-pull gauge.

For 200 mm/s, the maximum starting torque should be 0.5kgf.

Note : The rotation torque measurement reel is a dummy reel made with the following

maximum values :

Reel center width 14.0 mm x 100 mm diameter

Reel peripheral width 13.1 mm

Weight 740 g

B-3 Is there any problem with the tape feed lever height?

Is the aluminum bracket bent?

The feed lever height is as indicated below.

If the aluminum bracket is bent, it will degrade top film take-up torque or tape

feed lever operation.

If 8 mm feeders are set in place, it may also cause adjacent feeders to interfere with

other.

B-4 Is the ratchet (sprocket) advancing correctly for the tape feed stroke (8 mm)?

Set the feeder on the D-shaft table and move it to the pick-up point. Use I/O to

remove the 1st stopper, and set the cam shaft to 183˚ to 237˚ with the inching key

(on the CP-65, set to 184˚ to 235˚).

Check that the required feed operation is executing normally.

Checking the Ratchet Movement

B-5 Try Changing the Tape Feed Spring Force

Refer to section 2.1 “Disassembling the Feeder” of Chapter 2 of this part for details

on changing the tape feed spring.

C Low pick-up ratio, but not accompanied by the above

C-1 Is the part pick-up point offset?

Use an inspection instrument to measure the sprocket stop position.

Inspection instrument : DT-551 Feeder Pick-up Position

Check Unit

For details, refer to the DT-551 operation manual.
