4.3 Chip conveyor

The chips resulting from the machining are transported by a chip conveyor from the
work area to a collection bin. The chip conveyor has a conveyor belt that transports
the chips sideways and upward, so they can be dropped into the collection bin.
The chip conveyor does not transport the chips continuously out of the work area,
but at (adjustable) intervals.
The staff at the machine is not able to see when the chip conveyor starts the
transport operation. This results in conjunction with a variety of possible crushing or
shearing points in the work area of the machine and at the discharge point of chips
to an increased risk of injury.
Walking on the chip conveyor is always forbidden.
To avoid injury of the staff at the machine, the following measures have been taken:
• The movement of the chip conveyor is disabled when the work area door is
open. Backward movement in jog mode is possible in combination with the
confirm key.
• At the beginning of each conveying interval, the conveyor belt moves only a
small distance. This so-called start-up motion is to warn the staff at the machine
of the imminent start of the conveyor belt in order to allow them to leave the
danger zone.
• A discharge chute is attached to the discharge point of the chip conveyor, which
prevents direct access to the conveyor belt.
The discharge chute may only be removed if access to the conveyor belt is
prevented in another way (e.g., by a cover with a hole exactly matched to the
discharge opening).
• The chip conveyor has a button at the discharge chute, by which the running
direction of the conveyor belt can be reversed. This allows the operator to re-
move accumulated chips clogging the transport channel without dismantling the
discharge chute or other covers.
