ORKEL MC850 - Film Roller Storage; Wrapping Arms; Wrapping Arm Emergency Stop; Installing a New Film Roller in the Wrapper

The chamber starts, the elevator starts, the sub conveyor and hopper start. Material is fed into the bale
chamber. The feed amount is controlled by the ultrasonic sensor S29.
When set chamber pressure is reached (elevator slow threshold) the elevator slows down in order to reduce
the material flow into the chamber until the bale is finished.
Then, the net/film knife opens and the feed rollers start feeding the net/film into the chamber. A predefined
number of layers of net/film is laid on the bale, and the knife cuts the net/film.
The chamber opens and the bale is transported to the wrapper by the sub conveyor. The ultrasonic sensor
above the wrapping table detects the bale. Then the wrapping table receives the bale and tilts to its middle
position. The chamber door closes.
When the chamber door is closed, a new baling cycle starts. At the same time, the wrapping starts on the
wrapping table; the wrapping arms start and the film cutters release the film. The wrapping arms lay film on
the bale until a predefined number of revolutions is reached, before the film cutters cut the film.
The finished bale is then dropped from the wrapping table, either manually from the display unit, or auto-
matically if the automatic bale drop is activated.
There are several conditions that determine the desirable number of layers with wrapping film; type of
material, type of film and storage conditions and duration are especially important. Please read the manual
enclosed with the film.
NOTE: 14 turns/laps of the wrapping arm equals approximately 6 layers of film on the bale.
4.6 FILM ROLLER STORAGE
A storage magazine with a combined capacity of 11 rollers, is mounted on both sides of the compactor.
NOTE: 14 turns/laps of the wrapping arm equals approximately 6 layers of film on the bale.
4.7 WRAPPING ARMS
4.7.1 Wrapping arm emergency stop
The compactors wrapping arms are equipped with safety guards that stop the wrappers movement if
obstructed while wrapping. If the safety guards are triggered, there will be a popup message on the display
unit. The safety guards must be manually cleared from any obstruction. The machine will not start until activ-
ated by a new command from the display unit.
4.7.2 Installing a new film roller in the wrapper
1. Grab the tensioner on the stretcher and pull it to the right.
2. Open the lock lever, lift the centering cone and lock it in its upper position.
3. Replace the empty film roller.
4. Align the film roller with the centering cone, drop and lock the cone.
5. Thread the film as shown on Figure 4.5 and swing back the tensioner onto the film roller.
6. Fasten the film on the bale or the film cutter. Wrapping may now continue.
