Problems solved by technology

[0005] However, even in the case of dynamic formulations, the current environmental conditions (temperature, humidity, time...) at the place and time of the dosing are not taken into account, so that the formulation may not be suitable for subsequent use

Embodiment Construction

[0031] exist figure 1 A dosing device 1 is schematically shown in FIG. 2 , which has two storage containers 2 in which the material 3 to be mixed, for example liquid or solid, is located. If a lacquer is mixed, it can be, for example, pigments, fillers and solvents.

[0032] The material 3 can be conveyed from the storage container 2 via the pump 4 and the metering valve 5 towards the metering head 6 . Optionally, a treatment device 7 can be provided, for example a cooling device or a heating device, with which the material 3 can be processed. Treatment equipment can also be drying or humidifying equipment.

[0033] Although in the exemplary embodiment shown two storage containers with two materials 3 are provided, it is understood that in principle any number of different materials can be combined with the dosing device according to the invention.

[0034] Furthermore, the dosing device 1 contains a control device 8 which can control the various components of the dosing de...

Abstract

The invention relates to a dosing plant having a scale with a weighing chamber (16), a processor (32), an air conditioning module (34) arranged in the weighing chamber (16) and a mixing recipe display (30) ), a data transmission line, which can exchange data between the air conditioning module (34) and the processor (32) by using the data transmission line. Furthermore, the invention relates to an air conditioning module for detachable electrical coupling to a dosing device according to one of the preceding claims, wherein the air conditioning module (34) forms a closed structural unit and has an air pressure sensor (62 ), an air humidity sensor (54) and an air temperature sensor (52) and part of a data transmission line through which data can be sent to a processor outside the air module. Finally, the invention also relates to a method for dosing formulations using such a dosing device, wherein the ambient conditions are detected during the dosing of the materials to be combined and directly or indirectly adjust the mixing ratio accordingly.

Description

technical field [0001] The invention relates to a dosing device with which liquid and / or solid materials can be combined with high precision in a predetermined mixing ratio, ie according to a predetermined recipe. Background technique [0002] The task of dosing liquid and / or solid materials according to predetermined recipes is often carried out on scales. Here, recipes are typically generated from a database either statically (fixed recipes) or dynamically (formula-based recipes). [0003] EP 1 975 577 A1 shows a scale for gravimetrically calibrating drinking straws with a draft shield and integrated temperature, air pressure and air humidity sensors. [0004] DE 44 07 433 C2 discloses a scale for dosing, by means of which the dosing of the remaining components can be corrected in the case of misdosing of individual components within the recipe. Disadvantageously, only the mass percentages of the individual components are taken into account when dosing the individual com...
