Barco OptiSpin Brochure

OptiSpin

With OptiSpin, Barco offers a sensor for each individual ring spindle, allowing
accurate recording of the spindle speed and real-time detection of yarn break­ages. The stops are always assigned to the correct spindle, regardless of the
length of the machine.

Interfaces are available to the speed inverter of the ring frame, allowing to
increase the speed in case the ends down level remains below a defi ned
threshold. As a result, an optimum and consistent quality level is achieved at
maximum effi ciency.

All sensors are connected to a PC-based central unit. All information concern­ing production, effi ciency, ends down and slipping spindles is available on
the display or can be printed out on an external printer. Connected to Barco’s
SpinMaSter production management system, data from all machines is central­ized in one data base.

Principle of operation

The OptiSpin sensor is installed right below the pigtail. It consists
of a photo receiver facing a light emitting diode. During each
revolution, the yarn balloon interrupts the light beam twice.

The time between two successive interruptions serves as the
basis for the calculation of the balloon speed, while the amount
of light obstructed during the interruption is used as a rough
diameter measure.

Functionalities

- Accurate real time spindle speed detection allowing identifica­tion of slipping spindles.

- Indication of twist level based on spindle speed and delivery
speed.

- Immediate ends down detection, including detection of raffles.

- Classification of yarn breakages during up or down movement
of the ring rail and exact location in the bobbin build-up.

- Continuous yarn diameter estimation allowing detection of ad­ditional sliver or wrapping on draft cylinders.

- Flagging of problem spindles with section lights and lamp tree.

- Link to speed inverter for optimum control of spinning speed
based on breakage level, ring rail up-down movement and bobbin
build-up.

- Interface to roving stop unit.

- User friendly interface for set-up and reporting.

- Monitoring: produced weight, efficiencies and down time analy­sis.

Benefits

- Consistent quality.

- Increased efficiency.

- Reduced labor cost.

- Optimized speed profile as function of the bobbin build-up.

- Can be installed on all ring spinning frames.

- Independent of yarn count and traveler type.

- Simple mounting and cabling.

- Low power consumption.

- No moving parts, hence no obstruction for operators or auto-

mation devices.

- Limited maintenance.

Sensor Control Unit (SCU)

All sensors on one machine are connected to the SCU. This unit
offers a touch screen Windows-based user interface, USB interface
and Ethernet connection. The integrated OPC server allows a PC
to connect to the SCU via the OptiSpin BrOwSer allowing remote
operation and service. The standard screen on the SCU shows a
graphical machine view with color coded spindle status and side
by side machine details.

SpinMaster monitoring system

Through the OPC interface, all machines equipped with OptiSpin
can also be connected to the SpinMaSter production monitoring
system. All connected twisters are shown in a color coded mill
layout. Machines with off-standard conditions are automatically
flagged.
