By combination of decoiler, straightener and feeder machine into one unit, so called compact coil feeding line, which is positioned directly at the press, the needed space for a material loop of straightened material can be saved.The straightener-feeder is supplied with material out of a very small loop of not straightened material below the decoiler. And the decoiler is equipped with a variable speed drive as well as with a very sensitive loop control. By this way it is assured that there always will be enough material available for supply of the straightener-feeder.
In case that feeding lengths and stroke rates do require a bigger material stock within the material loop, the Compact Coil Feeding Line will be completed with a loop pit.
With our Coil Processing Systems you can process coil material width from 400mm to 1600mm, coil thickness from 0.6-6.0mm, coil weight up to 20000kgs.
Compact coil feeding line is design to make thick plate of auto parts stamping, such as brake pads, front pillar, Seat slide rail, center pillar, flip wheel and so on.
With YASKAWA servo motor and drive and MITSUBISHI PLC, the feeding line can achieve the very accurate feeding ±0.15mm. Moreover, the whole compact feeding system is only 4.5m length, which will save a lot of workspace for your press workshop.
Features of each parts of Metal sheet coil feeding line
1. Automatic loading coil car
Automatically lift the coil to the mandrel of the Decoiler Machine with loading coil car. And then the mandrel can expand and clamp the coil.
a) Loading capacity 5T-20T
b) Up-and-down movement the coil car by hydraulic cylinder
c) Horizontal movement by hydraulic motor
d) 2 Coil well-knit, no disperse
2. Decoiler:
a) Coil loading type: Single head with cantilever
b) Max. loading capacity: 5ton-20ton
c) Expansion type: Hydraulic
d) Brake type: pneumatic, stable and safe, also can prolong lifetime of the power system
e) Mandrel hydraulic expansion system. The hydraulic station provide power to drive the hydraulic cylinder to expand & draw back the mandrel to clamp coil or release the coil.
f) Press arm device to hold the strips, preventing coil loose. Further more, the press arm equipped with a PU roller to hold the strips, don`t scratching strip surface.
g) Support arm device. Driven by hydraulic-cylinder, it was use to guide and support strips, Further more, several sets of rollers installed in the device, and all rollers were chrome plated, the surface is very smooth, preventing scratching material surface.
h) Limit arm device, clamping coil in width direction, preventing coil collapsing when coil were too narrow. Further more, the width between two back gauge arms were designed adjustable by operate the manual wheels, coil width range is 70mm-1800mm.
i) Machine equipped with hydraulic station, providing oil pressure to drive the mandrel expansion & contraction and hydraulic cylinder.
j) Sensor device: electric eye loop control system, stable, safe and long lifetime. With the electric eye loop control system, the decoiler release strips automatically.(you can refer to the following image)
3. Straightener-Feeder
a) Structure: Servo motor driven, synchronous belt transmission, gear transmission
b) Servo motor and driver: Yaskawa, Japan
c) Straightening roller: 7 (upper 4/down 3)
d) straightening roller diameter:φ68mm
e) Pinch roller: 2pcs
f) Feeding roller: 2pcs
All the roller material is GCr15, after quenched, high frequency annealing, the hardness is HRC58°-60°and then precision polishing.
g) Gear: Material adopted 40Cr. The center quenched, teeth high frequency annealing and precision polishing.
h) Straightening adjustment: eccentric turbine worm adjustment, dial indicator display; Electric adjustment can be provided also
i) The entrance clamping roller: 2pcs
j) Release type: pneumatic
k) Feeding control: get signal from press encode or cam box, and controlled by PLC and display on HMI.
l) Material input guide roller: 1 group (manual adjustment)
m) Coil Inlet device. It equipped with chrome-plated rollers and guided strips to go through the straightening part.
n) Straightening device. It was mainly to press and flat coil head and end of the coil. Usually, the coil head is curvy, if without this device, the material is hard to go through the straightening part. But with this device, when the strips comes then entrance of the straightening part, the tip flatness device and press and flat the coil head and go through straightening device smoothly.
o) Handwheel: The operator crank the manual handle to adjust the accuracy of the straightening part.
p) Outlet bracket: assistant support material device. It was mainly used to guide strips from straightening part to press machine.
q) Control box. It was mainly used when coil run out and need to change a new coil and let the strips go though the straightening part at manual model.
r) HMI. The operator operate the machine and set data in this device.
s) Worm gear screw jacks device. It main used to adjust the height of feeding line.
t) Lubrication type: lubrication grease, manual grease bump lubrication
