Definitions

  • the invention relates to a method for the wet treatment of items of laundry combined to form laundry items according to the preamble of claim 1.
  • the laundry batches are treated gradually.
  • the batch of laundry can pass through a prewash zone, a main wash zone and, if necessary, a rinse zone.
  • the batch of laundry also pass through a post-treatment zone.
  • These different zones represent separate treatment areas, even if the entirety of the zones is formed by a drum.
  • these are added successively to the pre-wash zone or an inlet of the drum and then pass through the individual wash zones until they are ejected from the same again at the end of the drum.
  • the individual treatment steps take place in one and the same zone without the laundry items having to be moved to other chambers or zones.
  • a method and an arrangement for monitoring the operational sequence of a household washing machine are known.
  • the water inlet and the pumping out of the washing liquid, the heating process and the running up of the engine are monitored.
  • the monitoring is carried out for the purpose of the correct and safe functioning of control loops and control chains of the household washing machine.
  • a control arrangement for a washing machine with a drum receiving a single batch of laundry is known.
  • Various functions of the selected washing program, movement devices and the temperature of the washing liquid are to be controlled.
  • the control should be versatile and adaptable.
  • the WO 2012/026821 A1 discloses a conveyor washing machine for the industrial washing of textiles. This has an elongated drum in which chambers are arranged one behind the other, in each of which a batch of laundry can be treated. This makes it possible for this known conveyor-type washing machine to wash different items of laundry. The different batches of laundry are simultaneously subjected to different washing steps. At least one process parameter should be determined during at least the last two washing steps.
  • the invention is based on the object of creating a method for the wet treatment of items of laundry combined into laundry items, with which a reliable quality control of the wet treatment is possible.
  • a method for solving this problem has the measures of claim 1. Accordingly, it is provided to determine values for the temperature of the treatment liquid, the duration of each treatment step and movements of the drum and to compare these values with a corresponding predetermined reference value, specifically for each individual treatment step and for each individual item of laundry. By determining the values in this way and then comparing them with a reference, the wet treatment of the laundry items can be monitored in a very comprehensive and reliable manner. Through this extensive monitoring, on the one hand, the washing result is reproducible and, on the other hand, a high quality of treatment can be achieved. Such monitoring of the essential washing parameters is particularly advantageous for quality assurance but also for the documentation of the method.
  • a further advantageous embodiment of the present invention can provide that when the temperature of the treatment liquid and the duration of the treatment step and the movement sequences of the drum and the concentration of the treatment additive with the reference values of these laundry items, for which the match was determined, is released for a next treatment step and that if at least one value deviates from the corresponding reference value, the laundry item is not released for the next treatment step. If, accordingly, a match is established for all of the parameters mentioned, the laundry item is given a corresponding “marking”. This "marking" can be either analog, digital or virtual. In the case of a virtual marking, a corresponding “OK” is assigned to this item of laundry in the control device.
  • the control unit connects this "OK" with the batch of laundry for the rest of the wet treatment or for documentation and quality control.
  • a digital marking could take place in such a way that corresponding transponders or storage media are written on the items of laundry or in the items of laundry with the corresponding "OK signal". If at least one parameter does not match the reference value, the corresponding item of laundry is also given a corresponding marking, which can possibly lead to a repetition of the treatment step or to the item of laundry being discharged from the process.
  • the correspondence between the reference value and the determined values can take place within a tolerance range. For example, deviations of the determined values of up to 5% or up to 10% from the reference value are conceivable in order to still be assessed as a match.
  • an advantageous development of the invention consists in determining the concentration of at least one treatment additive in the treatment liquid and also comparing it with a corresponding reference value. This determination and the data comparison are also carried out for each individual item of laundry for each treatment step.
  • the titration in particular represented an uncertainty factor, since the concentration of the treatment additives was only determined randomly and sporadically. With this continuous documentation of the concentration for each batch of laundry, namely after each treatment step, an increased quality of the washing result can be achieved. This is particularly advantageous for items of laundry that must meet clinical requirements.
  • a display device such as a lamp or a screen, can be provided directly on the washing machine, on which the determined actual values are compared with the setpoint values, numerically or in color.
  • This representation can be shown separately for each treatment step and / or each batch of laundry. For example, a separate diagram is shown for each zone or for each chamber and / or for each laundry item for continuous washing machines having several treatment zones, in which the actual value is shown or compared with the target value or the reference value. This visual representation allows the treatment result to be seen at a glance. A person operating the washing machine can quickly and reliably see whether the actual values agree with the reference values or not.
  • the method can be given a high level of reliability and simple evaluation, in particular by means of colored marking.
  • the result of the comparison is stored for each individual item of laundry for documentation purposes, in particular on a storage medium assigned to the item of laundry.
  • This documentation allows a statement to be made about the quality of the treatment even after the end of the wet treatment. This information is particularly important for quality assurance.
  • the stored data can be used to determine why the desired washing result was not achieved.
  • the parameters can be changed so that the desired correspondence of all four parameters with the reference values is achieved.
  • a partial amount of the treatment liquid is removed from the drum, preferably from an outer drum, and a corresponding measurement, in particular a titration, of the treatment liquid is made or the measurement is made inside the drum.
  • This measurement of the concentration during the treatment process means that the wet treatment does not have to be interrupted become. On the one hand, this saves time and, on the other hand, the measurement is carried out precisely on the liquid in which the laundry items are treated. This enables a particularly high level of accuracy and thus reliability to be achieved.
  • Another exemplary embodiment can provide that the temperature of the treatment liquid inside or outside the drum is determined for each treatment step and for each item of laundry by a temperature measuring sensor.
  • the temperature measuring sensors can, for example, be temperature sensors inside the drum or measuring sensors that are positioned outside the drum and measure the temperature via infrared sensors.
  • a change in the direction of rotation of the drum or a number of pivoting movements of the drum is measured in order to determine the movement sequences of the drum.
  • the drums can perform different sequences of movements during treatment. For drums that are only swiveled back and forth in relation to the longitudinal axis or the central axis, the number of swivel movements is measured. For drums that make complete rotations, the number of rotations is counted to determine the motion sequences.
  • the number of rotations or pivoting movements can be measured from the outside in a simple and very reliable manner. Since the movement of the drum is transferred directly to the movement of the items of laundry, this is a particularly good measure for determining the mechanical load on the items of laundry.
  • the duration of the treatment step is determined and / or determined by changing the direction of rotation of the drum or by a specific number of pivoting movements of the drum.
  • a change in a treatment step is usually initiated by changing the direction of rotation or by ending the pivoting movements. Therefore, the mentioned movement sequences are good markers for determining the duration of the treatment step.
  • a further exemplary embodiment can provide that a batch of laundry is guided through the successive treatment steps until a correspondence with the references is established for all determined values.
  • a batch of laundry that is output from the washing machine and has not received approval for further treatment steps or delivery is included in the washing process or fed back into the washing machine. If necessary, the parameters that did not lead to a match with the reference values must be changed.
  • the single figure of the drawing shows a schematic side view of a commercial washing machine designed as a conveyor-type washing machine.
  • This commercial washing machine is a conveyor-type washing machine.
  • the method according to the invention is explained in more detail below.
  • the figure shows a conveyor-type washing machine 10 and a dewatering device designed as a dewatering press 11.
  • the dewatering press 11 is arranged behind the conveyor washing machine 10 as seen in the direction 12 of the laundry items passing through the conveyor washing machine 10.
  • a laundry centrifuge can also be arranged in place of the dewatering press 11.
  • the conveyor-type washing machine 11 has an elongated drum 13 in which a plurality of identical or different chambers 14 are provided. In the drum 13 of the conveyor-type washing machine 10 shown, thirteen chambers 14 are provided in succession in the direction of flow 12. However, the invention is not restricted to this. The invention is also suitable for conveyor washing machines 10 with a smaller or larger number of successive chambers 14.
  • the elongated drum 13 can be driven to rotate about a central axis of rotation which lies on a central longitudinal axis 15 of the conveyor-type washing machine 10.
  • This rotating drive can be done in various ways.
  • the drum 13 can be driven to rotate, but also only rocking or pivoting. Then the drum 13 is not driven to rotate with complete revolutions.
  • a combination of a rotating or pivoting or rocking drive of the drum is also conceivable.
  • a prewash zone a subsequent main wash zone and, if necessary, a rinsing zone and / or an aftertreatment zone, as seen in the flow direction 12, for example.
  • An inlet funnel 16 of the conveyor-type washing machine 10 opens into the first chamber 14 of the prewash zone.
  • the laundry items of the individual items are loaded into the first chamber 14 of the conveyor-type washing machine 10 via this.
  • This first chamber 14 is also the first chamber of the prewash zone.
  • the items of laundry are batchwise, i. H. in batches of laundry, washed.
  • a batch of laundry with a larger number of items of laundry is located in each chamber 14 of the conveyor-type washing machine 10 or, if necessary, only in some chambers 14.
  • the laundry items are treated with treatment liquid in a bath in the conveyor washing machine 10, in particular washed or optionally rinsed and / or equipped.
  • At least one treatment additive is added to the items of laundry and the treatment liquid. These can be detergent substances, disinfectants and / or bleaches, but also other washing aids.
  • At least one treatment additive is added to the treatment liquid with the laundry located therein in the first chamber 14 of the prewash zone, that is to say the first chamber 14 of the conveyor-type washing machine 10.
  • At least one treatment additive can also be added to at least one other chamber of the conveyor-type washing machine 10.
  • This can be, for example, the main wash zone, preferably the first chamber 14 of the same, the rinsing zone, if the conveyor-type washing machine 10 has one, and / or one be in the conveyor washing machine 10 existing post-treatment zone.
  • Different treatment additives can be added to the laundry items in the individual zones, for example detergents in the prewash zone, neutralizing agents and / or disinfectants in another zone and bleaching agents and / or finishing agents in yet another zone.
  • the conveyor washing machine 10 has suitable measuring instruments for measuring the amount, the content and / or the concentration of the at least one treatment additive in the laundry and the treatment liquid.
  • Corresponding measurement sensors are assigned to that chamber 14 or those chambers 14 of the conveyor-type washing machine 10 in which the treatment liquid and / or the laundry is to be measured with regard to their content or the concentration of the at least one treatment additive.
  • the concentration or the content of the at least one treatment additive in the treatment liquid detected by the at least one transducer is transmitted to an evaluation unit, not shown in the figure, which evaluates the measured values obtained or compares them with a reference value. If necessary, if the measured value deviates from the reference value, subsequent dosing of the treatment additive can be controlled or regulated.
  • temperature measuring sensors are assigned to at least one, preferably several chambers 14 of the various treatment zones.
  • the temperature of the treatment liquid can be measured via these temperature measuring sensors.
  • the measured values determined for the temperature are also transmitted to an evaluation unit or to a control unit, where they are compared with a setpoint value for the temperature.

  • a change of direction in the movement sequence of the drum 13 can also be used as a stop or start signal for the time measurement.
  • a number of several successive pivoting movements of the drum 13 are also suitable for determining the dwell time of individual items in the chambers 14 or washing zones.
  • the measured values determined for the duration of the individual items of laundry in the chambers 14 or the time interval that lasts a treatment step are also transmitted to an evaluation unit and compared with corresponding reference values. If the measured value deviates from the reference value, the treatment can possibly be extended or shortened.
  • the number of pivoting movements of the drum 13 or the completed rotational movements of the drum 13 is measured. These measured values are also forwarded to an evaluation unit or control unit and compared with a reference value.
  • the method according to the invention runs as follows with the conveyor-type washing machine 10 described above:
  • the items of laundry combined into batches of laundry are washed batch-wise in the conveyor-type washing machine 10.
  • a batch of laundry is preferably located in each chamber 14. If necessary, individual chambers 14 between successive items of laundry cannot be loaded with any items of laundry, for example at least one empty compartment 14 can be provided between items of laundry with laundry of different types.
  • the items of laundry are treated with treatment liquid in the chambers 14 at a predetermined temperature.
  • the heating elements are set accordingly for each chamber.
  • at least one treatment additive is added to the treatment liquid in at least one treatment zone of the conveyor-type washing machine 10.
  • different treatment additives can be added to the treatment liquid with the laundry contained therein.
  • the treatment of the laundry items of the individual items takes place in each chamber or in each zone for a predetermined duration. This means that each treatment step is limited in time. For a sufficient treatment result, the drum is swiveled several times or rotated completely for the wet treatment.
  • All four parameters namely the temperature, the duration, the concentration of the treatment additive and the movement sequence of the drum 13 are determined individually for each item of laundry and for each drum 13.
  • This quartet out Treatment parameters are transmitted to the system control or an evaluation unit and compared with the corresponding references. Both the measured values and the reference values are displayed visually. This can be done, for example, on a single display, so that an operator can see at a glance which parameters are or are not fulfilled for which item and for which chamber 14. However, it is also conceivable that each chamber 14 is assigned a corresponding display for the visual representation of the measured parameters and the corresponding references.
  • an “OK signal” is output by the evaluation unit, with which the corresponding batch of laundry is marked. This information is saved and saved for documentation or quality assurance of the treatment result. If at least one of the measured parameters does not match a reference, no "OK signal” is generated for this item of laundry. In other words, this batch of laundry does not meet the quality requirements and is not further treated or delivered.
