2.2 GENERAL BAR FEEDER DESCRIPTION
The automatic bar feeder SIR 52 P or SIR 52 F is used in the machine tools sector and more
specifically to automatically feed multi-spindle lathes.
The bar feeder has been designed to be installed instead of the lathe stock tube, thus replacing
the bar guiding and feeding systems. It allows round, hexagonal and square bars to be loaded.
The working cycle is controlled by a PLC fitted in the electric switchboard, able to dialogue with
the lathe control.
A LATHE
machines the bars loaded by the bar feeder.
B RACK MAGAZINE
stores the bars.
C TRAVERSE DEVICE
takes single bars, moving them from the rack magazine to the inserting device.
D DRIVE
drives the bar traverse device from the rack to the inserting device.

F BAR SELECTING DEVICE
selects bars.
G DRIVE
drives the bar selecting device.
H BAR INSERTING DEVICE
takes the bars and arranges them into the guide channels.
L CLAMP AND BAR PUSHER UNIT
inserts into and removes the bar from the collet.
Furthermore, it inserts into and removes the bar pusher from guide channels.
M FEEDING DRUM
inserts bars into lathe.
N CONTROL PUSH-BUTTON PANEL
controls all bar feeder functions.
P HYDRAULIC CONTROLS
adjust hydraulic oil flow.
Q ADDITIONAL PUSH-BUTTON PANEL
controls some bar feeder functions (not supplied in some models, being its functions
included into the lathe push-button panel).
R CUBICLE

A INTERLOCKED MOBILE GUARD. It is associated to
microswitch (B):
- when selector is turned to , the bar feeder
stops by opening the guard;
- when selector is turned to , the bar feeder
does not stop by opening the guard, but there are few
controls enabled, i.e. those necessary for setting up or
change the machining procedures; they are:
.
C AXIAL DISPLACEMENT LOCKING.
It is associated to sensor (D).
By releasing the lever, all lathe and bar feeder functions are
disabled.
E MOBILE GUARD.
Associated to microswitch (F).
By opening the guard, all lathe and bar feeder functions are
disabled.
G MOBILE GUARD.
Associated to microswitch (H).
By opening the guard, all bar magazine functions are
