OPTIONAL EASY STACKER
Use:
The easy stacker is designed to automatically
stack full 30 cell trays.
Construction:
The easy stacker consists of:
1 Infeed stopper
2 Tray stacker
3 Lift
4 Drive mechanism
The easy stacker is positioned at the far end of
the output conveyor and is partly situated
above and partly below it. Fixed feed carry the
weight of the easy stacker.
Process:
The infeed stopper just in front of the tray
stacker stops full trays. As soon as the tray is
detected by the infeed sensor (5) the stopper
releases the tray while at the same time
stopping the next tray. The tray is transported
towards the lift.
When the infeed sensor (5) does no longer
detect the tray, the lift moves the tray up
through the tilting plates, lifting up the trays
that are already present on the tilting plates.
When the lift is down again, the next tray is
supplied above the lift. Now the lift moves up a
few cm, stops, turns 90º and moves up again
until the tray is also placed on the tilting plates.
During the downwards movement, the lift stops
again to turn back 90º.
This sequence is continued until the top sensor
(6) detects the top of the stack of trays.
Normally this sensor turns ON when 7 trays
are on the tilting plate. The 6 top trays are easy
removable by hand. The lowest 7
th
tray must
remain on the tilting plates.
Safety:
Be careful with the optional easy stacker. This
unit makes unexpected fast and powerful
movements! Always leave the last tray on the
easy stacker to prevent the possibility of easy
entering of this unit with objects or body parts.
CAUTION!
Do not enter objects or body parts into the easy
stacker when it is running production. Always
leave a tray on the tilting plates.
Keep distant to the easy stacker! It makes
unexpected fast and powerful movements!
ATTENTION!
Do not enter objects or body parts into the easy
stacker when it is running production.
