IS3W/TTS Sensor Features
The IS3W/TTS devices are electronic sensors able to detect, due to sophisticated
control technique, the image variation, signalling possible failures detected during
the twisting process of yarns. Thanks to the image variation technique,
ambient/yarn conditions like humidity, conductivity and machine vibrations cannot
influence the IS3W/TTS device, furthermore the image variation technique
requires no contact with the yarn and allows a perfect monitoring without affecting
the characteristics
(e.g. tension) of the yarns. IS3W/TTS devices can be used for
yarn quality control (under both static and dynamic conditions) which, thanks to an
innovative patented technique (Smart Scanning Sensor) combined to the advanced
yarn control terminal SMART 200 TTS don't need complex wirings and long
installation times, allowing you to manage up to 200 positions.
The IS3W/TTS devices are very easy to use as they are ready to accommodate a
large variety of accessories that make them suitable to the quality control of any
type of yarn.
Function of the IS3W/TTS Sensors
The function of IS3W/TTS is to control whether the number of twisting applied to
the yarn is within the expected range for the article being processed.
Depending on type of yarn and application, the user can define the
minimum and
maximum number of acceptable twisting and, accordingly, program the sensors in
such a way that, when exceeding the defined values, they signal the failure and , if
required, stop the position (STOP output) .
In additional the sensor can be configured to perform the control in two different
modes
(TT or TB) :
1. TT Mode : the sensor analyses the profile of twisted yarns running inside the detection area
and calculates the number of twisting, thanks to the image variation.
In this operating mode, the two yarns, already twisted, run continuously inside the
detection area as shown on figure 1.
2. TB Mode : the sensor analyses the entry/exit movement (balloon) of one of the two yarns
(to be twisted) to/from the detection area, to calculate the number of twisting.
In this operating mode, the internal yarn runs outside the detection area, while the
external yarn enters/exit the detection area, according to the balloon, as shown on
figure 2.
The TT mode is suitable for non hairy yarns (tyrecord) showing a regular profile, while the TB mode is
suitable for hairy yarns that could alter the profile.
