2.1 BAR FEEDER GENERAL DESCRIPTION
The bar feeder in question has been planned and manufactured in order to automatically feed
the bars to be turned on the lathe.
It has been manufactured in two versions:
- VIP 80 E (standard version - the lathe on the right of the bar feeder)
- VIP 80r E (reversed version - the lathe on the left of the bar feeder)
The figure represents the two versions.
IMPORTANT:
this manual information (texts, tables, and figures) is referred to the standard
version (VIP 80 E), if not otherwise specified.
It can feed bars with different (round, square, hex) sections and of maximum length equal to
that of the spindle liner.
The operating cycle is directed by a PLC, integrated in the electrical control panel, which
interacts with the lathe controls.
It is equipped with a hand-held control that enables the operator to interact with all the
controls without forcing him to leave his work station.
The phase of preparation and tooling of the working change (diameters or different sections) is
extremely easy and quick.
Remnant ejection can take place with the feed either of the bar pusher or of the following bar.

2.1.1 MAIN COMPONENTS
A Magazine; contains the bars to be loaded.
B Sorter unit; lifts the first bar, from the magazine, and unloads it on the "bar drop control
device".
C "Limit stop" device; correctly positions the first bar, within the magazine, before it is lifted
by the bar selector unit.
D Bar drop control unit; inserts the bar onto the guide.
E Guide unit; directs the bar and inserts it correctly in the lathe.
F Carriage unit; inserts the bar in the lathe.
G Bar-pushing unit; moves the bar forward in the lathe, until its completion.
H Feathering device; is started by the arrival of the bar fore end.
L Drive feeding unit; transmits, by means of a toothed belt, the motions to the carriage and to
the bar pusher.
M Drive cam unit; drives the cams of the limit stop, bar drop control and bar selecting units.
N Hand-held control; sets the programming and starts the operative phases of the bar feeder.
P Electric cabinet; houses the electric control panel.

2.2 OPERATING CYCLE
Below are represented and
described the phases of the bar
feeder operating cycle.
- At the stop of the lathe
operating cycle, the bar pusher
(A) moves back to the limit stop
position.
- The bar pusher (A) and the "bar
drop control" unit (B) are lifted.
At the same time, also the bar
selecting unit (C) that loads the
first bar on the "bar drop
control" unit is lifted.

2 - TECHNICAL INFORMATION VIP80E
GB
2 - Pag. 5 / 14
- The "bar drop control" unit (B)
returns to its initial position
enabling bar insertion into the
guide (D). At the same time, the
bar selector unit (C) returns to
its initial position. Subsequently,
the guide lifts and sets the bar
in line with the loading axis.
- The bar is inserted into the
carriage lathe (E) that then goes
back to its initial position.
- The guide (D) returns to its low
position. The bar pusher (A)
lines up with the loading axis of
the lathe spindle.

2 - Pag. 6 / 14
- The bar pusher (A) inserts the
bar into the spindle liner. The
bar ejects the remnant (F) as a
residual of the previous
machining, and is positioned for
the facing.
The lathe operating cycle starts
with the beginning of the facing
phase.
At this point the bar moves forward
in order to be worked until the
workpiece is completed.
The last phase is repeated until the bar is finished, and a new operating cycle then starts.

2.3 SAFETY DEVICES
The figure indicates the position of the devices on the bar feeder.
A- Interlocked sliding guard: is associated with an interlock device (microswitch A1). At the
opening of the guard, in emergency condition, all the bar feeder and lathe functions stop. At
the closing of the guard it is possible to start the operating cycle again.
This one is endowed with a porthole allowing the visual inspection of the bar handling main
components.
B- Emergency push button: if started, each component of the bar feeder and of the lathe
immediately stops. After having normalised the operating conditions it is required to release
the button, with a voluntary action, in order to authorise again the bar feeder and lathe
setting into operation.
C- Drive fixed guard: prevents the access to the components in motion.

2.4 SAFETY AND INFORMATION SIGNALS
The figure indicates the position of the signals put on the bar feeder.
A- Danger of crushing upper limbs: do not put hands inside when there are components in
motion.
B- No guard removal: it is forbidden to use the bar feeder without the guards installed and in
operating conditions.
C- Danger of electrocution: do not enter the powered elements.
D- Danger of untimely shifting: before carrying out the first start make sure that the bar feeder
is adequately anchored to the ground.

A BAR LOADING AREA
B WORK AREA
2.4.2 Noise levels
During the machining, the bar feeder is not noisy.
The only phase where there can be some short-lasting peaks (85 dbA), is the bar loading one.
This measurement has been made in conformity with the regulation in force.
