Bobbin Sensor |
|
The circular Loom used in woven sack industry has 4–8 shuttle
bobbins which provides the weft tapes to circular fabric.
If this tape breaks, the fabric is wasted as it contains lots
of missing tapes. Our Weft Break sensor has been used widely to
detect these types of breaks and avoiding the wastage of fabric.
However there has been great demand for detection of near empty
condition of shuttle bobbin, so that bobbin can be changed before
it is completely empty. This results in zero defect fabric.
Usually to achieve this all the shuttle bobbins are replaced at once,
even if they are not empty. This results in lot of tape wastage on
‘ Not so empty bobbins’. Our bobbin sensor is designed to detect
the near empty condition of bobbin. When the sensor detects the near
empty condition of bobbin, the sensor stops the loom, so that only that
particular bobbin can be changed. This not only results in Zero defects
Fabric, but also Zero wastage on bobbins also.
The bobbin sensor is a highly sophisticated and state of the art sensor
to detect when shuttle bobbin nears empty condition. The sensor is based
on Infra Red to detect the presence of tape on bobbin, and a powerful,
fast microprocessor which calculates various timing and detects the near
empty bobbin and sends the trip signal to relay PCB. The relay PCB stops
the loom by opening the NC contact which is in series with Loom Stop button.
As the sensing mechanism is based on infra red principal, color of shuttle
bobbin tape and base color of empty bobbin may affect the performance
of sensor, however sensor will work faithfully on Light color tape and
all mild steel bobbins.
1. GREEN LED - When an object like shuttle bobbin comes with in sensing distance, the GREEN LED lights up. 1. WHITE LED - While loom running, when the sensor detects all the bobbins, the WHITE LED lights up. If it flickers, then one or more bobbins are not sensed properly 1. RED LED - When loom is running, WHITE LED is ON, if a bobbin gets to near empty condition, the RED LED will light up and operate a Relay on relay card. This will stop the loom immediately. |
