Barmag, MAE Melt spinning line 24Y

It is almost new and almost didn’t work on it as factory was bankrupt. This line was storage at heated factory. We think that he don’t need at all to invest money to start the line.

Composed of:
*4 automatic winders Barmag Mod. ASW1208,
*1 system of the granulated polymer unloading and conveyance,
*1 inverter,
*1 stress - stain test instrument Mod. MESDAN,
* set of laboratory instruments: 1 analytical scale Mod. 90BMARK 120A; 1 anemometer Mod.
Accuracy 0,1m/s; 1 stroboscope Pico 331; 1 electronic Thermometer Noronix HI 93530
* Electronic board,
* Spinnerets 36,72,144 round holes,
* Press for spin pack assembly, 2011 YOC
* all other new spare parts related to the line.
On Mae it can be produced only POY yarn

We was bouhght it only for virginchips. Maybe it is needed something to add and use it qith recycled chips.
The line was stopped at 2014. It is almost new. And many spare parts and additional instruments never used.

1.0 INTRODUCTION

MORODER POY lines, compact and simple, are designed for a cost effective production POY for textile applications.
Thanks to the use of the most up-to-date technologies, equipment by MORODER can meet all the quality and efficiency related specifications.
An extensive use of the most advanced and reliable electronic systems allows to reach a high accuracy in the control of all parameters and to properly monitor equipment behaviour.
Design based on actual user’s needs, strong construction and quality of components result in highly reliable equipment showing long working life and low maintenance.
The here offered equipment can be split in the following sections.

1.1 POLYMER CHIP FEEDING

Feeding of polymer chips and dosing of master batch / additives are automatically carried out, directly on the operative plant.

PET polymers are processed trough a dryer and crystallizer



1.2 EXTRUSION

Extruder, fed by the unit described in the previous section, is equipped with AC motors that, through reducer, drives extruder screw. Melt pressure is accurately controlled by means of sophisticated electronic systems which act on inverter controlling extruder screw motor.


1.3 SPINNING

Spinning heads, insulated in a proper way, are filled with diathermal oil vapours provided by a separate boiler with relevant piping and security valves.
Spinning heads house spinning pumps and spinning packs including melt distributors, pressure breakers, filtering screens and spinnerets new concept spinning pack allows long life.
First quality volumetric metering pumps specially designed for spinning are used; they are driven by synchronous AC motors controlled by inverters.



1.4 FILAMENT QUENCHING

Extruded and spun filaments are quenched in chambers fed by a laminar flow of conditioned air.
Quenching air is treated in suitable units provided with chilled air and fed to each chamber; a laminar flow of air comes out through chamber filters which ensure high distribution uniformity.



1.5 WINDING (TAKE-UP)

The drawn yarn is wound on cylindrical bobbins by automatic doffing winders .


1.6 CONTROLS

MORODER use the most advanced architectures suitable for the real industrial environments.
All standard FDY plants are conveniently operated through computer based supervisory systems, where all parameter setting, reading, alarm management, etc. are centralised; however, all process entities (temperatures, pressures, speeds) are actually controlled by dedicated intelligent units very close to the field, resulting in fast and highly reliable control loops.

Temperatures and Polymer Pressures:
Temperatures and polymer pressures are controlled by digital PID instruments.

Polymer pressure control loops act on extruder motor speeds through control drives.

Motors:
High-tech digital inverters are used for controlling synchronous AC motors and asynchronous AC motors.
Thanks to the most advanced digital inverters, a very high speed accuracy is achieved.
The performances of asynchronous AC motors controlled by such inverters are comparable to the ones of synchronous AC motors.

Doffing cycles are controlled by dedicated PLC.

Communications between the computers and the many intelligent controllers (themoregulators, inverters, etc.) are digitally performed by suitable serial lines. The above mentioned computer based supervisory systems provide production operators/ supervisors and maintenance technicians with a simple/safe interface and tools for an easy plant run.
