1 AUTOMATIC WINDER EN-CN

2 A big step forward 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, already well known, through the continuous automatic transfer of the ring bobbins from one machine to the other are: yarn quality of the wound package which is preserved being the bobbins prepared and automatically doffed on the ring frames, without any operator handling or loading into separate boxes; higher efficiency on winder; production output flow consistency and timed, as a single machine; minimization of winding room personnel. Most of customers select the link system solution whenever a new mill has to be set, or in alternative, whenever old ring spinning frames must be substituted. As a consequence, the real focus of Savio has been dedicated to propose an alternative solution, for all other mills where mainly existing ring frames are without automatic doffing, with the same winding efficiency of the link solution. Polar E Premium, has been designed to evenly process those yarn bobbins, whose formation is not originally favourable to reach that efficiency, keeping also the minimum number of operators.

3 Hopper The capacity has been increased thanks to the double alternate bobbin loading system on the peg. To achieve the full efficient peg loading rate, bobbins are mechanically spaced, bobbin shape identified by the profile reader sensor and properly oriented by the cross shaped rotating device. The profile reader sensor detects also the empty tube and diverts it into a separate dedicated collecting box. The enhanced hopper capacity and efficiency, allows a loading rate to cover the winding heads up to 7 spindles.

4 Peg feeding system An efficient loading system requires that: the oriented bobbins before be loaded on the relevant peg, are cleaned from any flying attached yarn by an air suction located in each of the two coupling sleeves. 7

5 Blow & Suction system Particularly designed to handle all types of bobbins, especially those ones where the yarn reserve is not at all present or very unfriendly placed (old ring frames without automatic doffing devices), the end finder station is now provided with a dedicated double action yarn retrieving system: A movable perforated ring disc blasts an air flow, against and around the cops body to remove the misplaced or entangled yarn tail. A knife bunch remover cuts any yarn layers at the bottom of the tube itself. A suction pipe system captures the detected tail to be inserted into the tube upper hole. 8 9

6 Intelligent bobbin distribution Fresh bobbins Bobbins prepared for winding process Empty tubes Yarn finders rejected bobbins Spindles rejected bobbins FRESH BOBBINS Hopper End finder Spindles End finder Spindles End finder Spindles Back up station EMPTY TUBES Tube control station Intelligent bobbins distribution: balanced feeding of all spindles Independent single End Finder Station feeds the allotted winding section. Up to N End Finder Stations to serve longer machines (up to 7 winding heads). This layout solution allows: The highest balanced flow rate of fresh bobbins for allotted sections (no idle spindles). Total reduction of bobbins traffic jam. Automatic removal of technological alarms and rejected bobbins, thanks to the Backup Station. Minimization of the operator intervention. 0

7 End finder station layout The machine design has been focused on the lay out of the end finder station as follow: the end finder stations, are distributed along the machine frame and consequently allow the proper balanced distribution feeding capability to the whole machine. The machine can be regarded as a coupling of o single machines; the centralized end finder system cannot permit same even balancing. With this balanced solution, Polar E Premium can have up to max. n 7 winding heads. Their positions being placed separately from the main bobbin/pegs belts flow, do not affect at all the efficiency of the system. Being front-side located, allow an easy intervention of the operator.

8 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 bobbins rejected by the winding heads for different reasons: Bad shaped bobbins. Bobbin with yarn remnants. Bobbins with technological alarms (off-standard quality yarn values). The station is able to prepare again the bobbin, with an high efficiency rate, because of the slow moving speed, and or to remove the faulty yarn portion, in case of a technological alarm. The diversified and specific movements are possible thanks to the identification system embedded on the machine and peg. The end result is also significant in terms of operator reduction, since no intervention is requested to the personnel.

10 Flexible cycle PC Independent movement of the package yarn suction nozzle Independent movement of the splicer Independent movement of the bobbin yarn suction nozze Independent movement of the yarn tensioner device Drum Traverse Tension sensor TENSOR Waxing device Yarn tensioner Flexible cycle Thanks to the individual motors and PC, the splicing cycle is automatically made, as per the actual requests of the splicing steps, improving, as consequence, the efficiency and production of the winder. Computer Aided Tension The winding tension is detected continuously by the Tensor, which interacts with the yarn tensioner device, through the machine PC, in order to adjust the load on the yarn as required. The Tensor, being positioned just before the drum detects on line the real winding tension. The sensor does not have any movable parts and performs as antiwrap system. Consequently: Greater productivity Consistent package quality (no presence of double yarns or yarn scrambling) Power and compressed Tensorflex (standard) air savings because In presence of elastomeric unnecessary splicing cycle yarn blended with wool/cotton are avoided the tension values must be Minimum wear of the parts diversified during the package Minimum yarn waste formation to ensure a perfect shape. 8 9

11 Anti patterning system Drum speed Package holder position Ratio between package/drum diameter drive in actual time Ribboning zone Drum speed Package holder position Ratio between package/drum diameter drive in actual time Ribboning zone Electronic anti patterning system On/Off modulation operates at critical diameters only. In the On/Off system, all the critical rates between package and drum diameters are memorized by the computer and consequently the drum is accelerated and decelerated, according to variable ramps, when there are possibility of ribboning formation. The system operates also during the acceleration after the splicing cycle. Computer Aided Package (optional) It gives a perfect package, without ribboning and without changing the drum s speed. The computer checks the distance between two consecutive layers and modify the ratio between package and drum diameters by micrometric variation in the inclination of the package holder and consequently in the driving point. 0

12 Controlling the winding process All parameters of the winding process are controlled by the Computer: yarn quality package quality production quality control of all peripheral units energy consumption. The Computer has a large touch screen and printer. The data are displayed in a descriptive and graphical form. Ethernet interface for connection to higher level information systems. The peripherals programme can be updated directly on the PC (also with remote loading). Spindle Monitoring System Each winding head is equipped with an alarm monitoring system. The operator is notified in real time of the ongoing alarm. Each spindle indicates technological as well as functional alarm Yarn count alarm Different count Package off standard Max n of splicers in the package Bobbin off standard Max n of cleares cut in the bobbin Yarn quality off standard (basic clearer) Max n of neps - thin - thick places -8 Examples of red ligths due to suction package/bobbin/clearer splicer Yarn quality off standard 9 Foreign fiber 0 Count variation Moire Pearl chain

13 Doffer trolley Energy saving The doffer trolley is electronically integrated with the winding heads and the machine PC. All the moving parts are driven by individual independent motors so to reduce the doffing cycle time to, seconds. The universal clamp is able to handle a certain different range of embty tubes conicity simultaneously without parts change. A new designed basket geometry to store different tubes conicity with no parts change, and to allow the easy tube colour recognition when different yarns are processed on same machine. The reserve yarn length is adjustable by the machine PC in order to meet any end user request. A fast patrolling speed up to 0 mt/min. in order to increase the doffing efficiency. The laser technology ensures the precise positioning of the doffer with the winding heads. Particular attention has been given to the suction system which represents the highest portion of the energy in the winding process. A special fan, with high performances aerodynamic blades in addition to the direct motor drive requests a minimum consumption of electric power. The motor fan, controlled by the machine PC through an inverter, adjusts its speed automatically in accordance with the actual working conditions and parameters. The yarn waste is collected in a separate filter box located in the machine headstock. The same fan provides also the vacuum to unload the travelling blower waste, once the blower reaches the proper discharge pipe also located in the headstock. The travelling blower waste is collected in a second separate filter box. In case of the Dust collection system device, the waste is unloaded in a third separated filter box. Yarn waste filter box Dust removal system filter box Travelling blower filter box Dust collection system (optional) A single suction unit for each head, located at the height of the balloon breaker, captures fibrils and dust produced when the bobbin is being unwound. Suction is created by a fan that serves two sections of heads. The impurities and dust are collected by a filter. PC
