New Press Feeding Line
- HEAVY DUTY, 1020mm x 10mm
FLOREANI & PARTNERS
BUILD TO ORDER CUSTOM DESIGNED
This is one of the "compact", heavy duty press feeding lines that we have designed and built to European auto makers.
It comes with differentiated roll center-distances, the upper section of the straightener-feeder getting lifted by a 350mm servocylinder, and various other very advanced technical solutions that are illustrated hereinafter.
It is composed of:
Powered decoiler, 20 t capacity with:
mobile base and auto. edge guide
hydraulic, powered snubber roll
Front conic rolls, for coil side containment ("programmable width")
hydraulic coil car
Servo straightener-feeder with:
powered, programmable adjustment of the work rolls
lower coil threading table
upper coil threading table, peeler
Hydraulic crop shear
Electric cabinet with Siemens S7 300 PLC and Simatic Operator Panel
Hydraulic power pack, 15 Kw motor
Safety back fencing and lightguards, to CE
The equipment features are as follows:
Decoiler
Max. load capacity kg 20000
Max. strip width mm 1020
Max. coil O.D. mm 1800
Coil I.D. mm 470-530
Planetary gearbox with ratio 1:22, transmission by triple chain with ratio 1:3
AC drive motor, 13 Kw - variable speed, 0-30 rpm with Inverter
Loop control by 2 rolls and proximity switch (or dynamic braking on other lines like this)
Hydraulic coil centering actuated by hydraulic cylinder, that moves 3+3 wedges
- Hydraulic and powered snubber with polyurethane-coated roll, of 120mm diameter:
arm rotation by hydraulic cylinder; minimum coil O.D. 700mm / max 2000mm
roll rotation by hydraulic motor, 315 cc. Roll coated with "Adiprene" rubber
- Two conic rolls:
the position of rolls set by the PLC, acc. to strip width
(forward/reverse motion by geared motor, and 90°-rotation by hydraulic cylinders)
- Mobile decoiler frame:
on 4 wheels & railways
motion by hydraulic cylinder with 500mm stroke
the position of decoiler detected by a potentiometer, and controlled by the PLC
/ with two limit switches
Hydraulic coil car
with minimum floor pit
up/down car stroke: 500 mm, with two cylinders of 100mm diameter
Servo straightener-feeder
with two pinch rolls of 300mm diameter
the pinch rolls pressed-down by 2 hydraulic cylinders
2+2 straightening rolls of 200mm diameter, in "progressive" location
3+3 straightening rolls of 150mm diameter, in "progressive" location
first deformation unit with the lower roll at a 380mm distance
second straightening unit with lower roll at a 150mm distance
thirds and fourth straightening unit with lower roll at a 100mm distance
the straightening rolls adjusted on 4 point, each point independently
- all supported by two rows of roll bearings
all lower rolls synchronized, with gears in oil bath
4+4 gearboxes^
A.C. servomotor, 75 kW
digital servodrive system by Control Techniques, Mod.: Unidrive - 75 kW
precision gearbox, ratio 1:20
_
Servo straightener-feeder max. speed: 60m / minute
- synchronised to the press by an absolute encoder:
99 work-programs with 9 different programmable-lengths for each program
adjustable feed pitch from .1mm to 9999.99mm
measuring wheel pressed-down by a pneumatic cylinder, 40mm diameter
feeding accuracy .2mm
mobile control panel for manual operation
operator panel: Simatic TP 170 Touch-Screen
openable machine frame to allow cleaning rolls and an easier coil threading
_
powered roll-setting, programmable (A.C. motor, 0.5 kW)
for the straightening rolls, 4+4 gearboxes and 4 linear potentiometers
– the system it is "dynamic": as the the coil gets fed to the press, the pressure on straightening rolls can be varied to adjust flatness
(as a new coil is introduced, the rolls-adjustment will return to "nominal" value)
_
Lower coil threading table, to support the strip
- during automatic cycle, the table will remain in 'low' position
it is moved up/down by about 100° by an hydraulic cylinder
Upper coil threading table with peeler, for material to work being thickner than 3mm
- at the table end, a hydraulic peeler can move-out by 200mm. During automatic cycle, the table will remain 'high' to its upper limit
Hydraulic crop shear
flat lower knife, with manually adjustable gap
upper knife V-shaped, 3°
the upper section slides on two columns with 120 mm diameter
1 hydraulic cylinder with 250mm diameter, 60mm stroke
2 hydraulic cylinders with 63mm diameter, 60 mm stroke / as blankholder
2 accumulators, 10 liters each accumulator, gas pre-loaded at 100 bar
Control system
PLC: Siemens S7 300 CPU 313C-3DP
1 Card, 32 digital inputs - 24 V D.C.
1 Card, 32 outputs - 24 V D.C.
Positioning system for the feeder: Control Techniques Unidrive Sp
Ethernet card for tele-service / Profibus
Touch Screen Operator Panel: Siemens Simatic TP170B
DP-DP coupler to be connected to main press control
electric cabinet dimensions: 2000mm x 2000mm
Hydraulic power pack
tank: 180 litres
A.C. Motor: 11 Kw
heat exchanger with electric fan
electrovalve for auto. accumulator-discharge
all other electrovalves required for the operation
