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 thus be used in particular in industrial kitchens in which items to be cleaned, for example trays, dishes and cutlery, have to be cleaned in large quantities.
- other areas of application are also conceivable.
- a large number of cleaning devices also known as cleaning devices, are known from the prior art, which can clean items and / or disinfect them.
- the design of these cleaning devices depends heavily on the various boundary conditions, such as the type of items to be cleaned, the contamination, the throughput or similar conditions.
- cleaning devices which are described, for example, in DE 10 2004 056 052 A1 or in DE 10 2007 025 263 A1.
- cleaning devices in canteen kitchens are combined with transport devices or transport systems for automatic delivery and / or removal of the items to be cleaned.
- cleaning systems are provided in many communal catering facilities, such as canteens in schools, hospitals or other facilities in which a large number of people are catered for, in which trays with contaminated crockery and cutlery are placed on a transporter. portband to be abandoned. This transports the items to be cleaned to the actual cleaning device, such as a dishwasher.
- the items to be cleaned are usually still sorted using personnel, 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 basket conveyor dishwasher or a through-feed dishwasher, for example in the form of a Hood dishwasher.
- a suitable manner for example a conveyor belt dishwasher, a basket conveyor dishwasher or a through-feed dishwasher, for example in the form of a Hood dishwasher.
- manual work is still required when sorting and entering the contaminated cleaning material into the cleaning device and / or when removing the cleaned cleaning material from the cleaning device.
- a technical and organizational challenge in many cases is that the contaminated cleaning items do not accumulate evenly. Particularly due to group dynamics, timetables or other circumstances that are not within the sphere of influence of the canteen kitchen, load peaks often occur, but also times when there is little or no items to be cleaned. This represents a considerable challenge for the planning of the personnel requirements and also for the planning of the design of the cleaning device.
- the design of the system and the personnel planning must generally be designed in such a way that the personnel can cope with the peak loads, but this does under certain circumstances outside the peak loads leads to an insufficient workload of the staff.
- the personnel planning and the design of the cleaning device must therefore be oversized in many cases.
- a dishwasher in the form of a commercial utensil or dishwasher designed as a program automat, 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 automatically loading the treatment chamber with items to be washed and / or for preferably optionally automatic unloading of wash ware from the treatment chamber.
- DE 4339111 A1 describes a dishwasher.
- the dishes are baskets are washed in cycle mode, the circuits of the washing device being put into operation only in their respective time interval within the washing program.
- a conveyor belt for the crockery baskets is controlled by means of appropriate switches in such a way that the crockery remains in the area of a washing zone during the washing process.
- DE 10 2004 049 392 A 1 describes a method for transporting items to be cleaned through a continuous dishwasher and onto a continuous dishwasher.
- the continuous dishwasher includes a washing zone, a rinse zone and a drying zone.
- the items to be cleaned are cleaned in the washing zone, rinsed clear in the rinse 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 the optimum transport speed for the process steps taking place in the respective zones.
- the transport devices are extremely inflexible and are generally not able to adapt to the various boundary conditions, in particular to sudden load peaks, backlogs during loading or changing requirements with regard to the type of contamination or of the items to be cleaned.
- peak loads therefore, as a rule, only the transport speed of the transport device can be adapted, for example by slowing down the transport or completely stopping it.
- the operating personnel must, in particular, particularly carefully sort dishes and distribute them on the conveyor belt, particularly in the case of peak loads, in order to optimally use the limited capacity of the cleaning device. If the load then drops, a somewhat less careful sorting and distribution is necessary, but the operating personnel must nevertheless be kept in order to be able to react again in the event of sudden new peak loads.
- This provision of personnel and, as a rule, machine overcapacity can lead to unnecessary additional costs when purchasing and operating the cleaning device.
- the use of clocked cleaning devices such as, for example, automatic program machines, for example in the form of hood pass-through dishwashers, is generally not possible or only possible if the entire cleaning system, including the transport device, is operated clocked.
- the cleaning system and the method should enable more flexible personnel planning with regard to the operating personnel and a more flexible configuration of the apparatus devices and preferably reduce the use of operating personnel.

- the speed v of the first transport device 136 can then be increased again, and the transport segment S1 reaches point P 3 , for example at a time t 4 .
- Unloading can be provided there, for example again manually or also automatically, for example via an unloading device 160. An unloading onto a tray trolley 166 is shown here by way of example.
- the drive diagram for the second transport device 138 shown below in FIG. 4 for transporting the transport segments S2 of the second transport segment group 164 can for example be identical to the drive diagram of the first transport segment group 162, but with a time delay.
- the cleaning program for the items 112 to be picked up on the transport segment S2 has ended, and the transport segment S2 is moved out of the cleaning chamber 120 at high speed until it reaches the point P 3 at the point in time t 2 and is unloaded there. Then this can be transported at medium speed until time t 3 , at which the cleaning program for the subsequent transport segment S1 of the first transport segment group 162 has ended, after which time up to time t 4, both transport devices 136, 138 with high speed operate.
- the speed profiles of the two transport devices 136, 138 can then be repeated periodically.
- the time profiles of the transport devices 136, 138 can be configured periodically, with a phase shift.
- the number of segments of the temporal course of the speeds can be adapted to the respective circumstances. It is also not absolutely necessary to keep the speeds constant in sections, but temporal variations of the transport speeds can also be seen in one or more sections.
