EMC 10: Picker Stays In After a Trim

If the picker remains engaged after a trim cycle, the machine may experience thread handling issues that can lead to thread wraps, trimming problems, or a Z Time Out Error.

Inspect the Picker for Burrs

The first item to check is the picker itself.

Carefully inspect the two tines on the picker for burrs, rough spots, or damage. Even a small burr can catch the thread and prevent the picker from releasing properly.

When thread becomes trapped on the picker, it can wrap around the hook area and interfere with normal machine operation, often resulting in a Z Time Out Error.

Check Picker Adjustments

If no burrs or damage are found, inspect the picker adjustment settings.

The EMC 10 Technical Manual contains the procedures for checking and adjusting the various picker positions required for proper operation. An incorrectly adjusted picker may remain engaged after trimming or fail to release the thread properly.

Additional Recommendation

If adjustment is required, Melco recommends using the proper Picker Fixture to ensure accurate setup. Contact your distributor for information on obtaining the correct fixture and adjustment tools.

Final Check

After inspecting and adjusting the picker, perform several trim cycles and test sew operations to verify that the picker engages and releases properly. Correct picker operation is essential for consistent thread trimming and reliable machine performance.
