TECHNICAL DESCRIPTION

AOP 151 Compact

Pallet wrapping machine is equipped with automatic system for film capturing, cutting and welding.
Safety fence is palced around the machine, doors are controled with safety switch.
System operation supervision on control cabinet with alpha numerical display with system for error
indication.

Automatic Power pre-stretch system for optimal film consumption and maximum savings.
Safety photocells on entry and exit in accordance with CE regulations.
CE mark.

Automatic Power pre-stretch system – POWER 2000

With this system all stages of film pre-stretching are improved. The system allows constant film
pre-stretching at 140%, 200% or 300%, where considerable film savings are achived. With this
stretching method the film is evenly put onto the pallet and therefore wrapping quality is much
better. With all manners of wrapping (also at uneven parts of pallet, different shapes of load) the
film always stays evenly stretched thus making wrapping easier and and more effective.
Outgoing film speed and rotating table speed are controlled by frequency inverter enabling even
greater film savings. Film loading onto carriage and its insertion in pre-stretch system is very easy.

 

Control tableau

Control tableau with multifunctional alpha-numerical display enables communication between
machine and the user.
Simple application system enables machine reseting, wrapping programm choice and manual
activating of all machine functions.
In case of error, auto-diagnostic system displays cause of error and helps user in error abolition.
If the user has trouble in error abolition, the secondary help system suggests method for error
abolition.

 

SEQUENCE OF OPERATION

Loaded pallet arrives on entry conveyers (not part of machine) onto roller conveyer on the
machine. Pallet is positioned in the middle.
At this time rotating table is still, film capturing device holds the end of the film.
Wrapping cycle starts automaticaly. Film carriage is mounted on colmun. Soft start (and stop) of
rotating table is standard equipment. Normal wrapping cycle beggins on the lower pallet edge with
low speed. After the first pallet corner acceleration of rotating table begins and achieves the top
speed. At the stoping the speed reduces gradually until complete stop in starting position.
Pallet wrapping can begin and stop in any position depending on choosen programm.
Top and bottom wraps, speed of film carriage movement depend on choosen programm.
At the begining of wrapping the film capture opens and enables complete pallet wrapping. Film
end blowing system blows the film end at the moment of wrapping under the film wrap.
At the end of wrapping film capturing device captures and holds the film end. Film narrowing
device narrows the film in welding place. Welding takes place against the teflonised bar and not
against the pallet. Hot wire cuts the film, welding system moves back and wrapped pallet is
transported out of the machine.

 

All machine functions are completely automatic.
