Problem & answerK-07
Cap Elevator Not Running or Caps Not Lifting
Also covers: Caps blocking the bottom of the cap hopper
Likely causes
- Caps (including caps returned from the chute) wedged at the bottom of the hopper where the elevator belt picks up (main cause)
- Hopper overfilled so caps press on the belt
- Cap level sensor in the chute signalling full
- Deformed caps
- Elevator motor or inverter fault
How to fix it
- 1Stop and isolate the cap elevator.
- 2Check the bottom of the cap hopper first: remove caps that are wedged or blocking where the belt picks up.
- 3Remove deformed caps.
- 4Do not overfill the hopper; keep the cap level below the guard.
- 5Restart: the elevator normally runs continuously once the blockage is cleared.
- 6If it still does not run, check the chute level sensor, emergency stop and the elevator inverter (E-01).
Technical note
The cap elevator lifts caps by gravity only, with no suction. Caps that do not sit correctly on a cleat fall back into the hopper, and a build-up of returned caps at the bottom is the most common reason the elevator stops.It is fixed when
Elevator runs continuously and keeps the cap chute full.
Stop it coming back
- Load caps loosely; never overfill the hopper.
- Remove damaged caps at loading.
