6.1.1 Bulk container feed station
The bulk c ontainer feeders (Fig. A.1), assembled
at the end of the machine, serve to deposit bulk
containers into the slots in synchrony with the
movement of the trays.
The feeder is composed of magazines (Pos. 1, Fig.
A.1)into which containers must be loaded manually,
and of a bulk container dispenser operated by
pneumatic cylinders (Pos. 2, Fig. A.1).
The action of releasing the container and inserting
it into the slot in the lamella takes place by
combining the pneumatic movement opening
the blades positioned at the lower end of the
magazine with the mechanical movement
(commanded by a cam) of a carriage holding
suction cups which grip the bottom of the
containers at the upper dead point and release
them in position in the lamella. To enable the
station in manual mode, press the button
(Page 1).
WARNING:
The construction of the _bulk container feeding
station does not permit protection of moving
parts at the sides in the tray area. A crushing
hazard sign is positioned on the fixed guard.
Adjustment
Intervention times may be altered by adjusting
the corresponding cams.
This applies to the container release command
and to activation/deactivation of the vacuum,
which must always take place before the suction
cup support carriage is at its upper dead point.
The vacuum must be released when the bulk
container is positioned in the slot in the lamella,
before the suction cup carriage reaches its lower
dead point.
For timing and cam settings, refer to point 5.2.1,
Setting working parameters
A number of different mechanical adjustments
are possible:
- By slackening the lock nuts (Pos. 7, Fig.
A.1) and adjusting the knob (Pos. 3, Fig.
A.1) you may adjust the height of the
magazine holder frame (Pos. 1, Fig. A.1);
the suction cup trolley’s stroke is
invariable, so you must adjust magazine
height to align the bottom of the containers
with the suction cups;
- height of the suction cup holder stems (Pos.
4, Fig. A.1) in relation to the decrease in
container height.
Replacement for format changes
Changes in bulk container geometry require
replacement of the magazines (Pos. 1, Fig. A.1),
the blades (Pos. 5, Fig. A.1) and, possibly, of the
suction cups (Pos. 6, Fig. A.1).
Consult the spare parts catalogue for correct
identification of parts.
