FLEXOGRAPHIC PRINTER SLOTTER FOLDER GLUERS
These machine consists of the following units:
Slotting and Creasing (Box Section)
Set Squaring & Counting Unit
1. FEED SECTION
The boards which have been aligned in the hopper are
kicker fed to a top: and bottom roller which carries them or to an air
suction conveyor belt system which in turn carries them into the first
printer unit The effect of the suction belt its to hold the board firmly
in place as it travels through the machine from hopper to box section.
2. PRINT UNITS
The boards pass through these units and are top Printed
by dies, which have been pre-set on Moulinex sheet in the plate room.
The die is held in place by a plastic strip which runs along the length
of the Moulinex and the back edge is held in place by Mathews Straps.
The ink is fed to the die face by an Anilox Roll, which has been "doctored"
to ensure the correct amount of ink: is applied. Flexographic ink is used
in our Case-Makers and both print units are identical
3. SLOTTER SCORER UNIT
This unit cuts the slots and creases the board to give
the box configuration. The setting up of this unit is accomplished by
dialling the panel sizes into an electronic counter system and the slotter-scorer
bosses move into position automatically. This system is most advantageous
because of the accuracy and the speed with which the machine can be set.
This unit is positioned to meet the glue flange when
the board leaves the "box section". Glue is applied by a wheel,
which is gravity fed from a small tank
5. FOLDER UNIT
Two conveyor belts with straight edge parallel bars
pick the board from the Gluer Unit. The bars are set to fold the board
on the crease at the beginning of Panel 2 and on the crease at the end
of Panel 3; Panels 1 and 4 are then folded under by a series of guide
bars glue flange com in contact with the inside edge of Panel 4 where
it remains sufficiently tacky to allow squaring - off to take place.
6. SQUARING UNIT
A series of vertically set movable bars in the back
edge of the Squaring hopper constantly nudge the folded boxes, which ensures
that the whole box is square and that the glue flange sets in the correct
7. COUNTING AND TAKE 0FF
This unit is pre-set for the number of bundled requirement.
It is electronically controlled by a magic eye counter. As the bundle
reaches the required number it is fed on a series of rollers to the take
off point, where they are either automatically tied by machine if required
and then stacked on a pallet.
Transport of blanks through machine by vacuum traction
Feed Unit to be kicker fed suitable for boards having
a warp of not greater than 1/4" in 1' (6 mm in 305 mm). Method of
Die mounting can be by various types, including straps and vacuum.
