The new winder POLAR/E PREMIUM was showcased by Savio in China on July 24 and 25. It introduces a completely new automatic continuous feeding concept, first introduced in the Savio link model POLAR/I DLS, coupled to a high capacity bobbin sorting system.
The Premium is provided with new and unique features to process bobbins produced by ring frames not equipped with automatic doffing device or no longer in “mint conditions”. This new free standing winder aims at the same winding efficiency of the linked solution.
It is indeed recognized that the maximum level of automation on the winding process is achieved by a direct link of the ring spinning frames to the winder. The advantages of direct linking are avoidance of manual handling of bobbins, with consequent better yarn quality and greater labor reduction. The direct link system is usually the first choice in case of green field projects. But in case of expansion or machinery replacement in existing mills, space availability becomes an obstacle. The only choice in such cases is the round magazine winder. Package and yarn quality will definitely improve, but it remains a labor intensive process.
This is where the new POLAR/E PREMIUM fits in – total machinery layout freedom, full automation of the feeding process, and getting fully geared to process bobbins of any shape and quality with greatest possible efficiency.
POLAR/E PREMIUM machine fact sheet:
• Higher loading rate for feeding up to 72 spindles: the innovative twin sorting delivers two bobbins simultaneously
• Feeding bobbin capacity up to n° 3000 per hour: a new high-speed optical scanner reads the profile of the bobbin. An air jet system distributes the bobbins between the two high-speed peg loaders. The system is the fastest available as it rely on minimum number of moving parts.
• End finder stations: End finder stations are designed to handle bobbins with yarn reserve at the bottom of the tube (in ring frames without automatic doffing, the presence of bottom reserve is usually erratic). The machine design has been focused on the layout of the end finder stations to optimize the bobbin distribution. The stations are placed along the machine and near the spindles and consequently allow an evenly and balanced bobbin distribution to the whole machine. Minimum distance between feeding and spindles is important in case of long machines. The machine comes with two end finder stations as standard, but according to the requirement of the process a third station can be added.
• Back-up station: A great help to ensure the highest efficiency of the winding process is given by the back-up station, which shall take care of all those bobbins rejected by spindles and the end finder stations for different reasons: bad-shaped bobbins, bobbins with yarn remnants, and technological alarms (off-standard quality yarn values). The back-up station is able to prepare again the rejected bobbin with highest efficiency rate, and/or to remove the faulty yarn portion in case of technological alarm.
Whenever a bobbin is rejected, the reason for the rejection is recorded onto a RFID tag embedded in each and every peg. Once the bobbins enters the back-up station, the appropriate sorting cycle is adopted. The result is that manual reprocessing by the operator is no longer required.
• Bobbin tube stripper: Whatever yarn left on the ring frames tube will be removed by the efficient tube stripper. Perfectly clean tubes can be returned to the spinning room – a truly “full automatic & hands free” process.
• Duo lot system: Later, in 2014, a further version of the Polar/E Premium will be introduced. This will allow to process two quality of yarns within the same machine.
