For six months or more now, a marked recovery in the global textile machinery market has been noticeable. This is also reflected in the demand for spare parts. Our customers’ production capacity is once again being fully utilised and they now require the pertinent spares and wearing parts, such as spinning and winding components, to operate their Oerlikon Schlafhorst machines efficiently. Our parts business serves around 5,000 customers in over 110 countries. We have an inventory worldwide comprising approx. 56,000 active original parts to the value of around CHF 40 million, covering over 90% of the items requested. Nevertheless, we have to buy in a small percentage of the spare parts required relative to orders. This currently poses a considerable challenge, because the dynamics and intensity of demand are extremely high for our suppliers too. We are very well aware that speed is of the essence in the spares business. We are working hard, therefore, to ensure that the level of service and performance expected of us are delivered as fast as possible in the usual manner. Bert Schlömer

Autoconer X5 – Ready, steady, flow! Intelligent automation for profitable production With its performance features like PreciFX, the new X-Change doffer, a new, easily comprehensible design for reduced handling, energy-optimised cooling concept and increased flexibility in terms of equipment and application range, the Autoconer X5 has enjoyed a successful market launch. We have proof of this in the many enquiries and orders received.

Set the pace: New, efficient logistics concept with central machining centre

In this issue we focus on the machine variants with automated material flow, show the advantages of intelligent automation and present the special merits of the Autoconer X5 automation concept.

All bobbins, piece bobbins, and deformed bobbins are prepared here for the winding process; the yarn end is securely fixed on the tube tip as tip bunch until the winding process starts. Bobbins that are not readied are routed directly to the manual readying station and do not adversely affect the further flow of material. Following the winding process, the final process stages are executed in the monitoring centre. The tube inspector assumes responsibility for distribution: empty tubes are extracted and discharged, tubes with cut-off pieces of yarn are optionally fed to the tube cleaning unit, tubes with yarn remains that can be unwound are re-fed into the material flow.

The advantages of automation are obvious: • • • • •

• •

Clearly structured process sequences, a reduction in the outlay on logistics Less dependence on the availability of operators Potential for improved product quality, especially in linked installations Reduction in handling and process stages (smaller number of fault sources) Reduction in handling and material costs (smaller number of tubes in the spinning mill cycle, fewer transport containers,…) Reduction in logistics costs because less space required Employees are relieved of heavy physical work

Short distances and demand-responsive logistics are typical of the new material flow concept. The new, central machining centre is positioned at the beginning of the machine.

Flexible configuration The bobbin readying station of the Autoconer X5 D/V can be flexibly configured. Thus capacity and functionality are optimally adapted to your feed material and to the material throughput in your plant. The effect: you always produce at the cycle rate required for your process sequence.

Plus factors of Autoconer X5 automation

New transport system saves up to 5% power

Take advantage of the plus factors of the Autoconer X5 automation concept for economical, efficient automation of your production facilities.

The former belt system has been replaced by a non-positive, energysaving slider system in the area of the monitoring centre and within the winding units. Power is only used when required. You save up to 5% of power compared to the preceding Autoconer generation. The belt system, also in energy-saving design, exists only where long distances must be covered: when feeding the bobbins to the winding units and when returning the empty tubes from the machine.

• • • • • •

Sturdy Caddy system that is gentle on the yarn, with a large, fixed foot, tensioning elements for secure fixing, wear-resistant metal reinforcement Clear material flow with low complexity, lower maintenance, and lower spare parts requirements Central machining and readying centre for bobbins and tubes Flexible configuration of the central bobbin readying station for maximum cycle rate Up to 5% reduction in power consumption thanks to the new transport system compared with predecessors New, non-positive transport system for higher reliability and trouble-free transportation Online quality monitoring (SPID) for targeted preventive quality assurance in linked installations (optional)

Intelligent material flow control The material flow is demand-responsive, i.e. as soon as a winding unit signals demand, material is fed. Maximum security of supply for the winding units is guaranteed even when the bobbin unwinding times are short, as 3 reserve bobbins are waiting at each winding unit. The Caddy situated in the winding position is positioned safely under the winding unit by means of magnetic force. In addition, magnetic gates and sensors are used for process-oriented control in the material flow.

Selecting the right level of automation Make a conscious decision in favour of the right level of automation on the basis of your requirements and we’ll supply the most suitable machine from the Autoconer X5 product family. Choose your individual equipment package from the winding technological performance features, and then you will be optimally equipped to determine the race for pole position in the market from the front. Some criteria that may help to decide which level of automation to choose are listed in the summary below.

Type D

Type V

Stand-alone machine

Direct link to ring spinning machine

+ Process sequence similar to type RM, with interim storage of the bobbin, i.e. “simple” step towards automation + Relatively small alteration in the process sequence, hence use of existing spinning machines and infrastructure possible with minor adaptations + High level of flexibility with regard to lot size, lot changes, yarn spectrum

+ Lowest staff requirement + Lowest logistics costs (accessories, tubes, boxes, carts,…), but new design of process sequences + Small space requirement + Maximum quality assurance + Preventive quality assurance at the ring spinning machine when utilising the optional spindle identification system SPID for online quality monitoring + Lowest fault quota with regard to handling, operation and process sequence + Optimum capacity coordination between ring spinning machine and Autoconer + Lower yarn break rates caused by the process, as bobbins are transported between ring spinning machine and Autoconer without contact

Higher productivity in the ring spinning mill Zinser 351 Impact FX offers new opportunities The quality advantages of compact yarns are state of the art. As well as improved quality, however, compact spinning offers other advantages in the spinning mill. One essential aspect here is the productivity of the spinning machine. To increase machine productivity, the spindle speed is normally raised. This is automatically accompanied by an increase in energy consumption,

however. Increasing the speed also always means increased wear of spinning components, such as rings and travellers. Reducing the twist makes it possible to achieve higher production while maintaining the same spindle speed. Power consumption and spinning component wear remain the same. The extent to which reducing the twist affects the yarn values must be noted, however. The twist multipliers commonly

used today are based on extensive experience, but compact spinning offers an opportunity here to reassess the previous standards. In many cases, the twist is already being reduced for compact yarns. A 10% reduction in twist is an entirely acceptable value with the same raw materials. Some mills now produce weaving yarns with a metric twist factor of Îąm 110-115 instead of the customary Îąm 125. To test the boundaries

further, we spun a CO yarn, Ne 80, in parallel as a classic ring yarn and as a compact yarn on a Zinser 351. The ring diameter was 36 mm for a tube length of 180 mm.

In addition to an improvement in quality, compact spinning thus offers the possibility of increased production without higher energy consumption or any increase in the wear on the spinning components. Further potential exists here for using the Zinser 351 Impact FX.

We were able to establish that, even when reducing the twist factor to αm = 99, the compact yarn is still serviceable. Another important factor is that all yarn values of the compact yarn are still better than the initial values of the classic ring yarn, even following the twist reduction.

Technology

PreciFX becomes established with 3 winding technologies Precision and staged precision winding for the Autoconer We’ve already reported on interesting applications for PreciFX packages with precise, pattern-free random winding. Now we are going to look more closely at the characteristics of precision and staged precision winding and their potential. Package characteristics typical features The basic characteristics of the various winding technologies and their typical distinguishing features can be defined in the appearance of the package structure with reference to a few parameters: • • • •

Angle of wind, winding ratio Yarn distance, position of threads in relation to one another Presence of pattern zones Package density

But what significance do these “theoretical physical laws” have in practice? Precise random wind PreciFX: With PreciFX, the package quality can be enhanced by the absolute absence of patterns with the proven package characteristic of random wind. It is easy to introduce drumless yarn displacement, as you are working with known winding parameters (e.g. number of groove per turn of the drum).

The application spectrum of random wind offers “virtually” unlimited flexibility, as another “drum” can be selected simply at the touch of a button in a range that is far more detailed (interim number of groove turns) and broadly based (expanded groove turn range) than the fixed groove geometry of drum displacement would ever permit. For this reason, this lends itself best to sales spinning mills with a broad profile of requirements, for example. Precision winding PreciFX: The characteristic grid structure is proof of the absolutely uniform yarn placing, with a constant distance between the individual threads. This results in a uniform package structure. The system causes the angle of wind to become smaller as the package diameter increases. This is accompanied by a uniform increase in package density outwards. With precision winding, a higher package density can be achieved compared with random winding due to the characteristic yarn placing and all yarn windings are well fixed. The degree to which the package density is increased can be adjusted with reference to selectable parameters such as yarn distance, starting angle of wind or yarn tension to suit the individual requirements. Secure fixing of the yarns prevents yarn movements and sliding of the yarns, resulting in very good unwinding properties.

Staged precision winding PreciFX: Staged precision winding combines the advantages of the PreciFX random wind (uniform density due to the virtually constant angle of wind over all diameter ranges) and of precision winding (precise, grid-shaped yarn placing with a constant yarn distance). These “staged precision packages” are suited in consequence to high-grade, absolutely uniform dyeing, for hard packages with requirements in respect of maximum packing densities, such as in twisting, for example. Thanks to the free selection of winding parameters, the structure of the package can be designed specifically in a way that cannot be achieved with either of the other two winding technologies. Outlook Realising precision and staged precision winding, not just for rewinding but also for bobbin processing, is the next step. For the production of hard packages in particular, it opens up new potential and applications in the future that have hitherto been the sole preserve of rewinding machines. And only the Autoconer 5 and X5 can offer this with PreciFX for bobbin processing.
