Kannegiesser launches ‘One Smart Laundry’

Over a period of eight days in a 6,000 m2 exhibition hall, the Kannegiesser Company played host to invited guests from more than 45 countries. The complete array of processing machinery and inter-related control systems for automating and enhancing the practical operating performance of industrial laundries large or small was on show. It was repeatedly demonstrated and subjected to detailed examination by a very knowledgeable and appreciative audience. 

In a logical progression around the floor, visitors were taken through the complete array of machinery, which demonstrated the Kannegiesser Company’s position at the very top of laundry machinery design and processing performance. Most machinery on display illustrated the continuous development effort which Kannegiesser exerts in each department of its manufacturing business. 

At Kannegiesser there is recognition that there is nearly always more than one effective solution to a variety of operational requests from widely different regions of the marketplace. The Kannegiesser approach to each processing solution is first to listen closely to the customer’s request and then to offer best ideas from a selection of Kannegiesser solutions, all of which will result in a successful processing result for the customer. 

In the wash section of the exhibition the three different versions of the market-leading PowerTrans continuous tunnel washer perfectly illustrated the Kannegiesser approach. The widely differing processing requirements across the laundry business demand options to achieve satisfactory efficiency and economy in the varying wash loads. Therefore, the three PowerTrans CTW on show illustrated different solutions to fast effective rinsing and moisture extraction using either high-speed spinning up to 800G or by high speed power pressing with up to 56-bar pressure. The advanced design of the inner drum on the PowerTrans was also cleverly illustrated by using a working wash load in a full scale model, with clear viewing made possible by enclosing the demonstration double chamber unit behind Perspex shields. 

This clear view of a working PowerTrans washing section also clearly showed how the varying sizes of the lifting beaters within the drum achieve effective mechanical action on the load in process. The drum design gives improved economy in use of the wash liquors and water. In the PowerTrans economical water use is typically being delivered at nearly three litres water used per kilo of work processed, by utilising a ‘dry transfer’ of the load from the last main wash compartment to the first rinse compartment. 

After washing, the drying stage presents its own processing possibilities for effective answers by the laundry machinery designer and manufacturer. The energy used in drying in the laundry is the single largest operating cost in most laundries. How the economy of drying affects both the cost and productivity performances in the plant is an important consideration when assessing the comparative merits of batch drying systems. 

The Kannegiesser Power Dry II, clearly illustrates how original thinking in the approach to each process within the laundry is successfully solved by the Kannegiesser engineers. On display was the new ECO-2-Power, energy saving concept, which improves energy efficiency and reduces energy consumption by 20 per cent by clever control of the airflow in the drying process when compared to existing processes. 

From batch drying to improvements in the technology of flatwork feeding, shown in the new Synchro, three or four station, flatwork feeding machinery development. The Synchro feeding system optimises processing of a wide variety of textiles from bed linen and duvet covers to tablecloths in mixed throughput work situations. High-speed servo-drives have been introduced to the pick-up and spreading mechanisms resulting in up to 30 per cent higher operating dynamic over conventional feeder drives, giving significantly higher performance and output consistency using field-tested, servo-drive technology. 

The clamps themselves on the Synchro have also been re- designed and this innovative solution makes it easier for the operator to load the item compared to the previous design. This improved clamp design, when added to the servo-drives of the Synchro, improves productivity by upwards of 10 per cent during a full working day. This new Kannegiesser clamp is an improvement on existing designs of clamp in use throughout the industry and its introduction is a further example of the attention to and implementation of, incremental improvements, which taken together, make very marked increases in operationalefficiencies at individual laundry plants. 

From Synchro to the new Speedline Towel Folder and what is very possibly the most significant new product development in dry-work folding for many years. It is also the development, which caused most comment about any Kannegiesser system on show. Speedline is now the fastest - and simultaneously, the most precise - towel folding machine currently available to the international laundry market, says the company. 

With a demonstrable throughput of 1200 pieces per hour, when processing mixed size batches, or up to 1500 pieces per hour when folding sorted batches, Speedline folders are set to become the industry ‘standard,’ high speed towel folding machine in markets where the earlier Kannegiesser folders already held that position. 

The Speedline folders effectively demonstrate why incremental design improvements produce extraordinary results in performance. In discussion we were shown how individual savings of as little as two or three milliseconds in time in feeding and folding operations and up to three full seconds time saved in measuring precise towel sizes during processing, all these savings combined, are estimated to save one full year of production output during each ten years of installed operational life. 

From Speedline to new sortation systems designed to automate and manage, easily and quickly the input of soiled garments into an organised sequence prior to processing industrial garments. Equipped also with a new design of clamp, which eases the operator action in attaching a garment, the incremental savings which accrue, add to the many developments shown at this Kannegiesser display of total manufacturing competence. 

With all the latest developments, the main theme at the exhibition was the ‘Smart Laundry’ where batches are tracked from loading into the Supertrack monorail system to being sorted in the correct stacks after folding, by either the Kannegiesser ironer line, or Kannegiesser towel folding systems. The Supertrack product is now fully integrated with all standard Kannegiesser manufacturing methods, less than one year after the move to the new Banbury factory. The enhanced Supertrack product range was fully demonstrated in Bad Salzuflen with new designs including a modular, floor level sorting system, with stainless steel chutes and an off the shelf ‘mini loop’ which is designed to replace step loading conveyors loading CTWs.

All Kannegiesser products have the same hardware and software support architecture incorporate the full tracking of batches and, where necessary, individual pieces moving through the ironer lines can be tracked. 

In the opinion of this observer, this exhibition was not merely a display of many different pieces of laundry processing machinery; it was actually a finely judged demonstration of why 66 years of continuous effort by this family-owned and directed company continues to set many standards in all areas where it chooses to direct its design and manufacturing efforts. Over the years of my observation I have seen the huge increases in operational efficiency which many laundry machinery manufacturers have brought to market for their industry. In the Kannegiesser exhibition described here at Bad Salzuflen, new benchmarks of design and manufacturing excellence have again been set, these will, in my opinion, be a very serious challenge to others who seek to emulate or even equal, this level of manufacturing excellence.
