A computer-implemented method for determining a delivery volume for use in a vehicle washing system. The method includes reading in a container data record for the container from which the substance is to be delivered by means of the dosing pump; reading in a digital level value representing a level measured in the container by means of at least one analog level sensor or reading in a digital pressure value representing a pressure measured in the container by means of at least one analog pressure sensor and reading in a digital density value for the substance to be delivered by the dosing pump, determining and outputting the delivery volume delivered by the dosing pump in a measuring time interval, based on the read-in digital level value or the read-in digital pressure value and the read-in density value and on the basis of the read-in vessel data record.

An automatic generation of washing programs for an automatic vehicle washing installation is provided. For this purpose, a washing program generator with a washing program generation unit is provided. This includes an input interface for reading-in an equipment data set which represents how the washing installation is currently equipped with machine components, a processor unit for computation of a group of function blocks based on the equipment data set read-in via the input interface, a user interface which is intended for outputting the group of function blocks computed by the processor unit and is intended for detection of a selection of the output function blocks, wherein the processor unit is further intended to compute a washing program based on the detected selected function blocks for operation of the washing installation.

Wash configurator

A system for modifying process data of a car wash based on captured evaluations of vehicle washes performed on the car wash, comprising: a set of mobile terminals, each adapted to perform an algorithmic evaluation process; and a control module, implemented on the car wash, for controlling and/or regulating the car wash based on the detected feedback signals encoding evaluations of vehicle washes performed on the car wash, and in data communication with the mobile terminals via the control interface.

Data exchange between a mobile terminal and a control module of a car wash for feedback of evaluation signals

An apparatus and method for treating a plastic molded article. The apparatus includes a treatment chamber that can be closed and temperature-controlled. A vapor generating unit generates vapor of a treatment liquid. A fluid connection between the treatment chamber and the vapor generating unit feeds vapor to the treatment chamber and returns condensate back to the treatment chamber. A pressure equalizing device transfers waste air at atmospheric pressure and equalizes pressure with the atmospheric pressure during treatment. The pressure equalizing device retains vapor and prevents vapor from escaping into the atmosphere. A vapor phase is generated by heating a treatment liquid to its boiling point. The treatment liquid includes a solvent that dissolves or solubilizes the plastic. The article is exposed to the vapor phase for a predetermined time and removed from the vapor phase. Residual treatment liquid present on the article is removed.

A device and related method for producing a ready-to-use solution from a concentrate and a diluent includes an inlet for the diluent; an inlet for the concentrate; an outlet for the solution; a line extending from the inlet for the diluent via a confluence where diluent and concentrate meet, to the outlet; a mixing container arranged in the line between the confluence and the outlet and having a larger cross-section than parts of the line, which are arranged upstream and downstream of the mixing container; and a metering pump for the concentrate, which is connected on the suction side to the inlet for the concentrate and on the pressure side to the confluence and which operates in a pulsed manner. The metering pump works with a clock frequency, in which a plurality of pump surges are attributable to the dwell time of the liquid in the mixing container.

A foam generator, in particular for a motor vehicle washing installation, includes a foam generation chamber having at least one inlet for water, surfactant and gas, in particular compressed gas, and one outlet for foam, and contains a fluid-permeable bed of loose particles. The bed fills the foam generation chamber sufficiently to prevent fluidization of the bed.

A method for cleaning vehicles by means of which the formation of marks caused by drying is prevented. The method comprises a rinsing step using water. In the method, the anions forming poorly soluble salts with alkaline earth metals dissolved in water are removed from the water, while cations causing the water hardness are retained. Furthermore, a vehicle washing system includes: at least one application device for applying rinsing fluid to a vehicle to be cleaned; and an ion-exchange device for removing anions from the rinsing fluid prior to the application to the vehicle.

A rotary brush for processing the surface of a vehicle includes a rotary brush main part and a plurality of fill material holders that are arranged on an outer lateral surface of the rotary brush main part spaced apart from one another in the circumferential direction thereof. Each fill material holder can be secured to the rotary brush main part in a plurality of stop positions spaced apart in the radial direction of the rotary brush main part.

The invention relates to a method for controlling a vehicle washing installation with the use of a light-section procedure, wherein at least one treatment device () and a vehicle () to be washed are moved relative to each other in the washing direction (L), the vehicle surfaces are illuminated by two light fans () starting from different positions, a first (FIG.) and a second (FIG.) two-dimensional depiction of the vehicle surfaces illuminated by the light fans () are recorded from shooting angles which are oblique with respect to the planes of the light fans, and are stored in a control unit () together with the relative position and/or relative movement of treatment devices () and vehicle (), the preceding steps are repeated during a traversing operation from one end to the other end of the vehicle (), and, during or after the end of the traversing operation, a three-dimensional representation of the vehicle surfaces is calculated from the two-dimensional depictions (FIG., FIG.) stored in the control unit (), and from the shooting angles, the relative position and/or relative movement and position data of the light fans (), and said three-dimensional representation is used in order to control the vehicle washing installation, in particular the treatment devices () arranged thereon.
