Definitions

  • the invention relates to a cleaning system and a method for cleaning items to be cleaned.
  • Cleaning systems and methods of the type mentioned can be used, for example, in the field of dishwashing technology, in particular in the field of commercial dishwashing technology.
  • the invention can be used in particular in canteen kitchens in which items to be cleaned, for example trays, crockery and cutlery, have to be cleaned in large quantities.
  • other areas of use are also conceivable in principle.
  • cleaning devices also referred to as cleaning devices, which can clean and/or disinfect items to be cleaned.
  • the design of these cleaning devices depends greatly on the various boundary conditions, such as the type of items to be cleaned, the level of dirt, the throughput or similar conditions.
  • cleaning devices which, for example, in DE 10 2004 056 052 A1 or in DE 10 2007 025 263 A1 are described.
  • cleaning devices are often combined with transport devices or transport systems for the automatic delivery and/or removal of the items to be cleaned.
  • cleaning systems are provided in many facilities for community catering such as canteens in schools, hospitals or other facilities where a large number of people are catered for, in which trays with soiled crockery and cutlery are placed on a conveyor belt to be abandoned. Through this, the items to be cleaned are transported to the actual cleaning device, such as a dishwasher.
  • the items to be cleaned are usually sorted using staff, waste is disposed of, and crockery, cutlery and trays are fed to the cleaning device in a suitable manner, for example a conveyor belt dishwasher, a rack conveyor dishwasher or a pass-through dishwasher, for example in the form of a hood dishwasher.
  • a suitable manner for example a conveyor belt dishwasher, a rack conveyor dishwasher or a pass-through dishwasher, for example in the form of a hood dishwasher.
  • a technical and organizational challenge is that the soiled items to be cleaned are not evenly distributed.
  • group dynamics, timetables or other circumstances that cannot be influenced by the canteen kitchen there are often peak loads, but also times when there are few or no items to be cleaned.
  • the design of the system and the personnel planning must usually be designed in such a way that the personnel can cope with the peak loads, which, however, may be outside of the peak loads leads to insufficient utilization of the staff.
  • the personnel planning and also the design of the cleaning device must therefore be oversized in many cases.
  • a dishwasher in the form of a commercial utensil or dishwashing machine designed as a program machine, which is designed as a hood or pass-through dishwasher and has a treatment chamber with at least one washing system designed as a recirculation system.
  • the dishwasher is assigned a loading/unloading device for preferably optionally automatic loading of the treatment chamber with items to be washed and/or for preferably optionally automatic unloading of items to be washed from the treatment chamber.
  • DE 10 2004 049 392 A1 describes a method for transporting items to be cleaned through a conveyor-type dishwasher and onto a conveyor-type dishwasher.
  • the conveyor dishwasher comprises a washing zone, a final-rinse zone and a drying zone.
  • the items to be cleaned are cleaned in the washing zone, rinsed in the rinsing zone and dried in the drying zone.
  • Transport devices are provided with which the items to be cleaned are transported in the conveying direction at a transport speed that is optimal for the process steps taking place in the respective zones.
  • CA 885 576 A describes a warewashing apparatus and, more particularly, an improved and simplified form of a warewashing system that includes a warewashing machine and an associated continuous conveyor belt that conveys racks of soiled dishes to be cleaned by the warewashing machine.
  • U.S. 3,550,755A describes an endless conveyor for a dishwasher including a table with an endless rail for supporting an endless train of trolleys which in turn carry baskets of dishes, the trolleys being interconnected by links.
  • the train of trolleys is moved intermittently so that only one trolley at a time is brought with its basket in front of an operator who places the soiled dishes in the basket.
  • the trolleys carry the dishes through the dishwasher, where they are washed and sterilized, after which the clean dishes can be removed from the baskets.
  • Certain trolleys carry lane wipers of novel design.
  • U.S. 3,122,235 A describes warewashing machines and in particular a high capacity type of machine in which racks or the like for transporting soiled dishes can circulate in a closed horizontal path through the warewashing apparatus.
  • DE 10 2011 004853 A1 describes a conveyor device for feeding dishes to at least one conveyor belt of a commercial conveyor dishwasher, with a conveyor system for conveying the dishes, in particular for feeding trays or tray-like dishes, cutlery and/or other dishes.
  • the invention is characterized by an unloading station for automatically unloading the items to be washed from the conveying device transversely to the conveying direction of the conveying system, in which the trays with or without cutlery lying on them can be aligned upright and parallel to the conveying direction of the conveying system in order to be adjustable on a conveyor belt of the conveyor dishwasher .
  • the invention also relates to a flight-type dishwasher and a combination of this dishwasher and the conveyor device.
  • the invention also relates to a method for loading a flight-type dishwasher with a conveyor device and a preferred use of the same for loading a dishwasher with trays or tray-like items to be washed.
  • U.S. 3,698,407 A describes a revolving rinse tub for an oval, endless conveyor-type dish conveyor for a dishwasher that reuses water to convey material removed from dishes to a waste collection system, with some of the water also being used for a power scraper to clean the dishes just prior to washing and rinsing to clean. This saves the use of fresh water for the power stripper and thus saves water.
  • the use of a recirculating sink eliminates the need to have a power scraper as one of the units in the warewasher and this reduces the overall length of the warewasher by one unit and results in a space saving of approximately 20 square feet.
  • the final hot water rinse, after spraying on the dishes, is directed into the rinsing tub to refill and heat the water.
  • the transport devices are extremely inflexible and are generally not able to adapt to the various boundary conditions, in particular sudden peak loads, backlogs during loading or changing requirements with regard to the type of dirt or the accumulating items to be cleaned.
  • peak loads only the transport speed of the transport device can therefore usually be adjusted, for example by slowing down the transport or stopping it completely. These measures then apply to usually the entire cleaning system.
  • the personnel planning for many cleaning systems must be dimensioned in such a way that it can always cope with a peak load.
  • the operating personnel usually have to sort dishes very carefully and distribute them onto the conveyor belt, particularly during peak loads, in order to use the limited capacity of the cleaning device optimally. If the load then drops, a less careful sorting and distribution is required, but the operating personnel must still be kept available in order to be able to react again in the event of sudden new load peaks.
  • This provision of an overcapacity in terms of personnel and, as a rule, also of machines can lead to unnecessary additional costs when purchasing and operating the cleaning device.
  • the use of clocked cleaning devices such as program machines, for example in the form of hood type dishwashers, is generally not possible or only possible if the entire cleaning system including the transport device is operated in a clocked manner.
  • the cleaning system and the method should enable more flexible personnel planning with regard to the operating personnel and a more flexible design of the apparatus and preferably reduce the use of operating personnel.
  • the terms “have”, “have”, “comprise” or “include” or any grammatical deviations thereof are used in a non-exclusive manner. Accordingly, these terms can refer both to situations in which, apart from the features introduced by these terms, no further features are present, or to situations in which one or more further features are present.
  • the expression “A has B”, “A has B”, “A comprises B”, or “A includes B” can both refer to the situation in which, apart from B, no other element in A is present (i.e. to a situation in which A consists exclusively of B), as well as to the situation in which, in addition to B, there are one or more other elements in A, e.g. element C, elements C and D or even other elements .
