2 Design There are currently two versions of the Evolution Cube available: 1. Batch processing with a towel size that corresponds to predefined measurements 2. Mixed processing with a maximum of two different towel sizes that correspond to predefined measurements To be able to run the system as flexibly as possible, a fold-away transfer table can also be supplied, which enables manual feeding into the Tematic Pro towel folding machine. The foldaway transfer table with feeding belt ensures operating safety and allows for interim feeding and folding of special laundry items that cannot be processed using the Evolution Cube. If the Evolution Cube cannot recognize or grasp the towel corner for some reason, the dropped laundry item is automatically sent back to the start of the process via an integrated return belt, i.e. into the separating hopper. This itemreturn system means that it is not necessary to remove towels from the machine by hand. In effect, the Evolution Cube resolves its detection or grasping errors itself. Quality control One could of course assume that quality control by means of human inspection during manual feeding of towels would also be eliminated due to the rationalization of operating personnel. In this regard, JENSEN is working on automatic quality control using a camera system that identifies damaged or soiled towels and initiates sorting of these items. Output Depending on the towel size and the textile quality and thickness, the Evolution Cube can process between 400 and 600 towels per hour as a daily average. The towels should conform to the following dimensions: Minimum size: 900 x 500 mm (35.4 ” x 19.7 ”) Maximum size: 1200 x 600 mm (47.2 ” x 23.6 ”) Application Due to its lack of dependence on operating personnel, the Evolution Cube is particularly suited to multi-shift operation. It is naturally advisable to have a single person monitoring the overall process when operating multiple Evolution Cubes. The Evolution Cube is primarily used in central laundries for hospitals and textile rental companies that process standardized hotel linen. Currently, the Evolution Cube can process standardized dry laundry corresponding to the aforementioned dimensions on a viable, productive basis. After the next devel- opmental stage, the Evolution Cube should meet the requirements of hotel laundries that process textiles of a different quality and, more importantly, a wide range of different textiles. Combination Laundry items not conforming to the indicated dimensions, as well as thicker items such as shower mats, are folded manually using the Tematic Pro. Hand towels and bath towels are processed using the Evolution Cube. Pre- sorting of towels before the finishing process can also increase the dryer output. Basically all dry laundry items should be automatically fed to the folding stations via a bag conveyor system, and removed in a precisely stacked manner by means of a Jenway conveyer belt system in order to obtain an ideal process flow. When processing 50% standardized and 50% other types of dry laundry, two Evolution Cubes, each with one integrated and two freestanding Tematic Pro folding machines could 1200 mm (47") be installed. It is not absolutely necessary to purchase an Evolution Cube together with a new Tematic Pro if the latter item is already available in the laundry. The Evolution Cube can be connected to an existing, recently produced Tematic Pro; however, in this case the software must be updated. To achieve maximum capability, an overhaul of the existing Tematic Pro is recommended. This can be performed by JENSEN service technicians during commissioning. 1.

N O. 9 september 2009 efficient and precise laundry management for satisfied customers refereNCes A&M Blanchisserie Basse Meuse S.A., Liège, Belgium Joseph broers and his son marc broers, General manager of A&m blanchisserie basse meuse . Absolute control with the futurail counting and sorting system for restaurant linen. The Broers family business was started as early as the 50s and was known at the time as La Meuse laundry. In the 60s, Joseph Broers took over the company from his father and concentrated on dry cleaning. Today, the company Ardennes & Meuse (under the management of Marc Broers, the 3rd generation) specializes purely in textile rental services for the hotel and restaurant business. The Broers family has operated one of the most modern industrial laundries in Europe since February 2009 in an entirely new building 4200 m2 (45,200 sq. ft.) in size in the industrial area of Vottem near Liège. The new laundry has been designed to handle a capacity of 125 tons (275,600 lbs) of hotel and restaurant linen, and 4 months after commissioning processes up to 20 tons (44,100 lbs) per 8-hour working day. Linen transportation between the processing stations on the soiled and clean sides is handled by the Futurail bag storage and conveyer system, which provides all stations with linen on a consistent basis and according to centrally controlled requirements, so that employees can remain at their working stations. Communication between the laundry expedition and production areas is carried out by means of PCs. Automation of the operating process and central production monitoring and control has enabled employee and machine productivity to be increased considerably. A&M supplies 400 different customers in an area of up to 120 km with 80% of their personalized and 20% of their standardized hotel rental textiles (hotels in all categories) and restaurant linen, of which 90% are standardized items. Before washing, the soiled hotel laundry is sorted into 50 kg (110 lbs) lots according to customer and category using the Futurail Tri-Sort system and forwarded in bags to the storage system. The 50 different articles of table linen are classified using a special Futurail sorting and counting system, then stored in bags and forwarded. This unique sorting system for table linen is able to determine the exact number of soiled items delivered, such as napkins and tablecloths. The count of soiled items is automatically captured and is compared with the delivery contracts for end customers. The laundry operating system communicates the delivery priority to the central JENSEN production monitoring system, which steers the selection of lots that must be washed first. The production monitoring system already knows the type and number of laundry items that must be delivered on the same day, even before washing. In this manner it is possible to punctually deliver clean napkins in the afternoon to customer "y" that come from a load of soiled napkins sent by customer "x" the same morning, without having to hold large stock levels. The central JENSEN production monitoring system supplies the local laundry operating system with exact data for creating delivery notes and invoices for end customers. Marc Broers is proud of this unique counting and sorting system for table linen: "This system makes our job considerably easier and helps us to react quickly to customer requirements." To be able to continue using the existing steam heated Senking Universal P50-14 continuous batch washers and their washer extractors, the Broers family decided on the construction of an energy-efficient laundry that is equipped with no more than an extremely small steam boiler. The two new Senking Universal P50- 13 batch washers and the ten Senking DT 60 dryers, together with six new ironers, are gas heated. The bed linen and towels are washed using the low-temperature process from Christeyns at 60°C (140 °F) in the gas-heated continuous batch washers, and table linen at higher temperatures in a steam-heated washing tunnel. Gas usage for the entire laundry was reduced to 0.085 m3 /kg (1.4 cu.ft./lbs) of dry linen, which corresponds to an energy usage of 0.9 kWh/kg (1400 BTU/lbs). The internal water recycling system in the Senking batch washers and the Christeyns microfiltration system reduce the overall water consumption in the laundry to 3.5 litres per kg (0.42 gal per lbs) of dry linen. The Futurail bag conveyer system supplies clean laundry to the finishing area as required. Six Tematic Pro folding machines handle the towel items. The Maximat 900 folds and stacks thick bathrobes. Two ironer lines, each equipped with a Quickfeeder and an Extreme with two stations, are used purely for processing sheets, which are fed without handling the corners. The duvet covers are processed via one or two lanes in the Logic Plus, while large items of table linen are fed via one or two lanes in the Variant 2000. Two ironer lines handle the smaller items. Marc Broers attributes the success of his business to the harmonious working environment and reliable personal contacts in the laundry industry: "Our success is based on three strong pillars: customers, business partners and our staff. Many years of personal and expert advice from our business partners, particularly JENSEN, have enabled our company to develop from a laundry to one of the most modern textile rental operations in Europe. I see automation not only as a way of increasing productivity and logistically optimizing work processes, but also as a means of significantly improving working conditions for our staff." A&M Blanchisserie Basse Meuse S.A. officially invites all companies in the laundry sector to an open day to present their new operation. All Jenfo readers are also cordially invited!
