2.4.2 Work stations
There are two work stations, on the front side (PL1 fig. 2.4.1.1) and one at the rear
end (PL2 fig. 2-2) of the machine’s infeed conveyor. From these stations the operator
can load the product to be packed on the infeed conveyor (3 fig. 2.4.1.1), paying
attention to the pusher or other product pushing devices found on the conveyor.
From the work station the operator has a full view of the machine’s work zone (Z fig.
2.3.1); therefore he can easily check whether or not there are persons exposed while the
product is being loaded.
In case of danger, the operator may stop the machine through the emergency stop
button located on the infeed conveyor (4 fig. 2.4.1.1).
ATTENTION
Loading of the product in manual mode must be done only if the machine is not
equipped with the automatic load system.
2.4.3 Machine preparation stations
There are four preparation stations (PC-PL1-PL2-PL3 fig. 2.4.1.1) since the operator or
maintenance technician to prepare the machine will have to enter almost all the work sub-
zones (ZA-ZC-ZD-ZE fig. 2.3.1).
1. In zone ZA the film spool is mounted and the film inserted through the unwinding roller
and the forming tunnel, with the probable adjustment of the tunnel itself according to the
dimensions of the product (operator, PC or PL1 station).
2. In zone ZB adjustment of the product pusher rods according to pace of the product itself
(maintenance technician, PL1 or PL2 stations).
3. In zone ZC insertion of the film between the wheels of the longitudinal sealing group
(operator, PC station) and eventual adjustment of wheel pressure (maintenance
technician, PC station).
4. In zone ZD insertion of the film between the wheels of the transversal sealing group
(operator, PC station) and eventual adjustment of the sealing teeth, pressure of the
sealing and knives (maintenance technician, PC station).
5. In zone ZE no preparation interventions are done but is normally used to gain access to
the transversal sealing group (PL3 station fig. 2.4.1.1).
6. In zone ZF adjustment of the product brushes according to pace of the product itself
(maintenance technician, PC station).
