2.5 Residual risks
The Comet N is a linear filling machine in
automaticcycleofsuperiorsizefortheproduction
of cornets, cups, tubs and other containers filled
with ice cream, sorbet and water ice, on more
lines ranging from one to six according to the
dimensions of the container to be processed and
the production values to be reached.
The filling process takes place according to a
pre-set cycle as laid down by the filling
specifications agreed upon with the customer.
Themachineincludesabaseunitfortransferring
thecontaineralongthemotionaxisofaconveyor
beltandasequenceofstationsfitforcarryingout
the required filling cycle with ice-cream and/or
other ingredients.
The process includes:
- placing the container on a conveyor belt
directly from an appropriate dispenser provided
with a storage unit
-conveyingthecontainerplacedontheconveyor
belt, under the work stations
- completion of the filling cycle according to a
predefined sequence with the expected
simultaneous action of the different stations.
- closing and/or sealing the container with a
protective film or an airtight lid.
- product ejection and discharge by means of
conveyor or pick-up
The motion of the conveyor belt is intermittent
and it is achieved by a suitable intermitter
activated by an electric motor and an inverter.
The stations are activated by cams controlled by
the same main drive shaft, with reference to the
approach phases of the former to the containers,
whilstthedosingphasesoftheice-creamandthe
liquid and solid ingredients (chocolate, nuts,
biscuits, etc.) are operated pneumatically.
The issue of adapting the machine to suit the
needs of the operator has brought about several
problemsthathavebeentackledinthefollowing
way:
- centralizing the controls on a single control
board for the following functions:
- automatic cycle with dispenser feeding.
- completion of a plane of work at ergonomic
height for set-up operations.
- ergonomic layout with the stations arranged
along the machine’s axis near its frontal part.
- application of planning criteria to the work
stations and their components such as the fillers
and the dispensers which enable an easy
maintenance and a quick format changeover.
- presence of fixed boards
The following residual risks arise from this kind
of machine; they are highlighted as follows:
- Tray carrier belt.

4.3 Electrical connection (Refer to ALL. 1 Electric diagrams )
Make sure that the bypass valves of the ice-
creampipes(Part3Fig.4.1)areconnectedtothe
dosers (Part 4 Fig.4.1) as required.
Connecttheice-cream tubesfromthefreezersto
the ice-cream dosers by means of the bypass
valves (Part 5 Fig.4.3) located above the
pneumatic valve.
After performing all the electric and pneumatic
connections, it is necessary to perform the
following checks:
• Makesurethereisnoforeignmatterinsidethe
machine that could prevent its operation.
• Release the emergency button.
• Rotate the main switch.
• Open the air supply.
• PresstheJogbuttonandcheckthattheshutters
move from left to right (Part 2 Fig.4.1) looking
at the machine from the operator’s side.
• Press button Stop to stop the chain.
4.4 Checking the direction of rotation
4.6 Connection to the freezers
WARNING:
Ifthedirectionofrotationis incorrect, invert the
phases on the terminal block.
This operation must be performed by qualified
personnelonly,familiarwithlawsregulatingthe
prevention of industrial accidents.
Before starting the freezers connected to the
machine, place a container below the ice-cream
bypass valve and another container on the
opposite side of the machine, under the product
collection slide.
4.5 Pneumatic connections (Refer to ALL. 2 Pneumatic diagrams )
onnect the machine to the supply of compressed
air. The minimum working pressure is 6 bar.
If the pressure is below 4 bar, a special pressure
switch calibrated by the manufacturer stops the
functions of the machine.
Forinformationontheconsumptionofairandon
the dimensions of the supply pipe, see 3.7

tected against short-circuits.
WARNING:
The connection must be made exclusively by
competent technicians familiar with accident
prevention legislation.
It is recommended that the power is taken from
a master switch fitted with thermal overload
cutoutandultra-rapidfusesofadequateamperage.
WARNING:
The differential cutout switch must be class “A”
