UNIT DESCRIPTION
PACKER
Use:
The Packer is designed to receive a random
supply of eggs and assemble these eggs into
fixed patterns of 25, 30, 36 or 42 eggs and
place them with the pointed end downwards
into a tray.
Construction:
The packer consists of:
1 Infeed conveyor
2 Infeed gate
3 Main drive
4 Roller track
5 Cup conveyor
6 Transfer lever
7 Vacuum head
8 Vacuum system
Attached to the packer are:
9 Electrical cabinet
10 Operating panel
Process:
Eggs are entering the packer on the infeed
conveyor where the eggs may be graded. On
this belt oversized-, misshapen-, cracked- or
dirty eggs should be manually removed.
Egg pressure control sensors (20) on the sides
of the infeed conveyor prevent accumulation of
eggs on the infeed conveyor.
The eggs run into the infeed gates where they
are detected (21). When all gates have
detected an egg, the roller track moves one
step forwards receiving the eggs from the
gates in between 2 rollers on the roller shafts.
Because of the shape of the rollers and their
rotating movement, during each step forwards,
the eggs move with their pointed ends more
towards the outside of the rollers.
At the main drive position, the egg lifters lift the
eggs on the round end up while flaps are
guiding the pointed end into the cups of the
cup conveyor.
A cup detection sensor (22) stops the system
when remaining eggs are detected in between
the roller track and the cup conveyor.
The cup conveyor transports the eggs towards
the transfer lever position until the first line of
eggs is detected by the start transfer sensor
(23).
The vacuum head on the transfer lever moves
down to pick up the eggs and transports them
towards an empty tray on the outfeed
conveyor.
