Description

Die Erfindung betrifft eine Anlage zur Dosierung und Mischung unterschiedlicher flüssiger Stoffe mit einer Vielzahl von Vorlagebehältern für die unterschiedlichen Stoffe, wobei an jedem Vorlagebehälter ein von einem Steuerungsrechner gesteuertes Auslaßdosierventil angeordnet ist und jedem Auslaßdosierventil ein auf einer mit dem Steuerungsrechner verbundenen Wiegeeinrichtung angeordneter Mischbecher zuordbar ist.The invention relates to a system for metering and mixing different liquid substances with a large number of storage containers for the different substances, an outlet metering valve controlled by a control computer being arranged on each storage container and each outlet metering valve being able to be assigned a mixing bowl arranged on a weighing device connected to the control computer.

Eine derartige Anlage ist aus US-A-4,585,148 bekannt. Diese bekannte Anlage dient zum Mischen von Farben, wobei die einzelnen Farben jeweils in einem Vorlagebehälter mit Dosierventil vorgehalten werden. Zur Erstellung einer Farbmischung wird ein Mischbehälter einem Wiegeplatz zugeführt und anschließend werden rechnergesteuert die einzelnen Vorlagebehälter in den Bereich des Wiegeplatzes verfahren, derart, daß sich das jeweilige Dosierventil oberhalb des Mischbehälters auf der Wiegeeinrichtung befindet. Anschließend wird dann die dem Rechner angegebene Farbmischung erstellt und der Mischbehälter mit der Farbmischung kann entnommen werden.Such a system is known from US-A-4,585,148. This known system is used for mixing colors, with the individual colors being held in a storage container with a metering valve. To create a color mixture, a mixing container is fed to a weighing station and then the individual storage containers are moved under computer control into the area of the weighing station in such a way that the respective metering valve is located above the mixing container on the weighing device. The color mixture specified on the computer is then created and the mixing container with the color mixture can be removed.

Mit einer derartigen Mischanlage lassen sich zwar weitgehend fehlerfreie und genaue Dosierungen und damit Mischungen erreichen, jedoch ist aufgrund der Ausbildung der bekannten Anlage die Mischkapazität begrenzt, da nicht beliebig viele Vorlagebehälter vorgesehen werden können bzw. ansonsten ein erheblicher konstruktiver Aufwand erforderlich ist, weil sämtliche Vorlagebehälter zum Wiegeplatz transportierbar sein müssen. Diese begrenzte Mischkapazität stellt insbesondere bei der Parfumerprobung einen wesentlichen Nachteil dar. Darüber hinaus ist von Nachteil, daß insbesondere bei einer Vielzahl von Vorlagebehältern die Misch- und Dosierzeit relativ lang wird, da jeweils der betreffende Vorlagebehälter in den Bereich des Wiegeplatzes verfahren werden muß. Weiterhin ist bei der bekannten Anlage von Nachteil, daß diese nicht vollautomatisch ohne Aufsicht von Bedienungspersonal betrieben werden kann. Es ist bei der bekannten Anlage nämlich erforderlich, zunächst den Steuerungsrechner mit den entsprechenden Mischzusammensetzungen zu programmieren, wobei dann anschließend sichergestellt sein muß, daß die entsprechenden Mischbehälter bereitgehalten werden. Es ist somit eine Überwachung durch Bedienungspersonal erforderlich.With such a mixing system it is possible to achieve largely error-free and precise dosing and thus mixtures, but due to the design of the known system the mixing capacity is limited, since it is not possible to provide an arbitrary number of storage containers or otherwise a considerable design effort is required because all storage containers must be transportable to the weighing place. This limited mixing capacity is a major disadvantage, particularly in perfume testing. In addition, it is disadvantageous that the mixing and dosing time becomes relatively long, particularly in the case of a large number of storage containers, since the storage container in question must be moved into the area of the weighing station. A further disadvantage of the known system is that it cannot be operated fully automatically without the supervision of operating personnel. In the known system, it is namely necessary to first program the control computer with the corresponding mixing compositions, after which it must then be ensured that the corresponding mixing containers are kept ready. Monitoring by operating personnel is therefore necessary.

Demgegenüber besteht die Aufgabe der Erfindung in der Schaffung einer Lösung, mit welcher eine fehlerfreie, genaue Dosierung und Mischung unterschiedlicher Flüssigkeiten zur Parfumerzeugung ohne Überwachung durch eine Bedienungsperson vollautomatisch und möglichst schnell ermöglicht werden soll.In contrast, the object of the invention is to provide a solution with which an error-free, accurate metering and mixing of different liquids for perfume production without monitoring by an operator should be made possible fully automatically and as quickly as possible.

Diese Aufgabe wird mit einer Anlage der eingangs bezeichneten Art erfindungsgemäß dadurch gelöst, daß zur Mischung flüssiger Duftstoffe zur Erzeugung von Parfums die Wiegeeinrichtung mit dem Mischbecher unterhalb der Auslaßdosierventile auf einer Mischbecherstrecke verfahrbar ist, und daß vor der Mischbecherstrecke ein mit der Mischbecherstrecke verbundener Mischbecherspeicher mit Transportband angeordnet ist, wobei jeder Mischbecher mit einer Codierung versehen ist, welche von einem mit dem Steuerungsrechner verbundenen, am Ende des Mischbecherspeichers angeordneten Scanner ablesbar ist.This object is achieved according to the invention with a system of the type mentioned at the outset in that, for the mixing of liquid fragrances for the production of perfumes, the weighing device with the mixing cup can be moved on a mixing cup line below the outlet metering valves, and in front of the mixing cup line a mixing cup storage unit connected to the mixing cup line with conveyor belt is arranged, each mixing cup being provided with a code which can be read by a scanner connected to the control computer and arranged at the end of the mixing cup memory.

Die erfindungsgemäß ausgestaltete Anlage kann nach einmaliger Einrichtung, insbesondere nach Bestückung des Mischbecherspeichers mit einer Vielzahl von codierten Mischbechern, vollautomatisch ohne Überwachung durch Bedienungspersonal betrieben werden, wobei gleichzeitig nur sehr kurze Mischzeiten erforderlich sind, da der jeweilige Mischbecher selbst mit der Wiegeeinrichtung auf der Meßstrecke zu den einzelnen Vorlagebehältern hin verfahren wird. Dabei wird gleichzeitig eine sehr hohe Mischkapazität ermöglicht, da aufgrund der stationären Anordnung der Vorlagebehälter bei entsprechender geometrischer Anordnung derselben eine Vielzahl von Vorlagebehältern vorgesehen werden können. Darüber hinaus ist die erfindungsgemäße Anlage äußerst flexibel, da auch bei laufendem Betrieb durch Einfügen eines entsprechend codierten Mischbechers in den Mischbecherspeicher sofort eine augenblicklich benötigte Mischung erstellt werden kann, ohne den sonstigen Ablauf zu stören.The system designed according to the invention can be operated fully automatically without monitoring by operating personnel after one-time setup, in particular after the mixing cup storage has been equipped with a large number of coded mixing cups, at the same time only very short mixing times being required, since the respective mixing cup itself with the weighing device on the measuring section the individual storage containers is moved. At the same time, a very high mixing capacity is made possible because of the stationary arrangement of the storage containers with a corresponding geometric arrangement of the same, a plurality of storage containers can be provided. In addition, the system according to the invention is extremely flexible, since even during operation, by inserting an appropriately coded mixing cup into the mixing cup memory, an instantly required mixture can be created immediately without interfering with the rest of the process.

In Ausgestaltung sieht die Erfindung vor, daß die Vorlagebehälter von einem Inertgas mit regelbarem Druck beaufschlagt sind. Durch dieses Inertgas-Polster, z.B. aus Stickstoff, in den Vorlagebehältern werden konstante Vordruckbedingungen an den Dosierventilen gewährleistet, so daß eine zuverlässige Steuerung der jeweiligen Abgabemengen möglich ist.In an embodiment, the invention provides that the supply container is pressurized by an inert gas with a controllable pressure. Through this inert gas cushion, e.g. nitrogen, in the supply containers constant pre-pressure conditions are guaranteed at the metering valves, so that a reliable control of the respective delivery quantities is possible.

Vorteilhaft ist zwischen der Mischbecherstrecke und dem Mischbecherspeicher ein Handhabungsgerät zum Umsetzen der Mischbecher vom Speicher auf die Strecke angeordnet. Diese Ausbildung ist dann vorgesehen, wenn das Transportband des Mischbecherspeichers nicht direkt mit der Mischbecherstrecke gekoppelt ist.A handling device for transferring the mixing cups from the storage device to the section is advantageously arranged between the mixing cup section and the mixing cup storage device. This design is provided when the conveyor belt of the mixing cup storage device is not directly coupled to the mixing cup section.

Nach einer besonders bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß die Mischbecherstrecke als Drehtisch mit kreisförmig verfahrbarer Wiegeeinrichtung ausgebildet ist. Dabei sind die Dosierventile bevorzugt auf einer Kreisbahn mit dem Radius der Wiegeeinrichtung angeordnet. Diese Anordnung der einzelnen Elemente der Anlage ist besonders platzsparend und deshalb günstig.According to a particularly preferred embodiment of the invention, it is provided that the mixing cup section is designed as a rotary table with a weighing device which can be moved in a circular manner is. The metering valves are preferably arranged on a circular path with the radius of the weighing device. This arrangement of the individual elements of the system is particularly space-saving and therefore inexpensive.

Um eine noch platzsparendere Anordnung zu erreichen, kann auch vorgesehen sein, daß jeweils mehrere Dosierventile gruppenförmig zusammen angeordnet sind.In order to achieve an even more space-saving arrangement, it can also be provided that several metering valves are arranged together in groups.

Schließlich sieht die Erfindung auch vor, daß am Ende der Mischbecherstrecke ein weiterer Mischbecherspeicher mit Transportband angeordnet ist. Eine solche Ausbildung ist dann vorteilhaft, wenn Mischungen auf Vorrat hergestellt werden sollen und nicht sofort benutzt werden, d.h. es kann dann z.B. über Nacht eine ganze Serie von Mischungen erstellt werden.Finally, the invention also provides that at the end of the mixing cup section a further mixing cup storage device with a conveyor belt is arranged. Such training is advantageous if mixtures are to be made in stock and are not used immediately, ie a whole series of mixtures can then be created overnight.

Eine vollautomatische Anlage zur Parfümdosierung und -mischung weist eine Vielzahl von Vorlagebehältern 1 zur Bevorratung unterschiedlicher Duftstoffe auf, wobei in der Zeichnung nur beispielhaft einige Behälter dargestellt sind. Diese Vorlagebehälter 1 sind über Leitungen 2 an ein Inertgassystem 3 angeschlossen, dem über Ventile 4 mit regelbarem Druck Inertgas aus Inertgasbehältern 5 zuführbar ist. Durch dieses Inertgaspolster, z.B. aus Stickstoff, wird in den Vorlagebehältern 1 ein konstantes Druckniveau eingestellt.A fully automatic system for perfume metering and mixing has a large number of storage containers 1 for storing different fragrances, only a few containers being shown as examples in the drawing. These storage containers 1 are connected via lines 2 to an inert gas system 3, which via valves 4 with adjustable Pressure of inert gas from inert gas containers 5 can be supplied. By means of this inert gas cushion, for example made of nitrogen, a constant pressure level is set in the storage containers 1.

Jeder Vorlagebehälter 1 ist über eine Leitung 6 mit einem elektrisch gesteuerten Auslaßdosierventil 7 verbunden, das an einen Steuerungsrechner 8 angeschlossen ist und von diesem rechnergesteuert betätigt wird.Each storage container 1 is connected via a line 6 to an electrically controlled outlet metering valve 7, which is connected to a control computer 8 and is operated by this computer-controlled.

Wie aus Fig. 2 hervorgeht, sind die einzelnen Auslaßdosierventile 7 bevorzugt kreisförmig oberhalb einer Mischbecherstrecke 9 angeordnet. Dabei ist die Mischbecherstrecke 9 als Drehtisch 10 ausgebildet, wobei am äußeren Umfang des Drehtisches eine Wiegeeinrichtung 11 für einen Mischbecher 12 angeordnet ist, welche kreisförmig verfahrbar den einzelnen Auslaßdosierventilen 7 zuordbar ist.As can be seen from FIG. 2, the individual outlet metering valves 7 are preferably arranged in a circle above a mixing cup section 9. The mixing cup section 9 is designed as a turntable 10, a weighing device 11 for a mixing cup 12 being arranged on the outer periphery of the turntable, which can be assigned to the individual outlet metering valves 7 in a circularly movable manner.

Vor der Mischbecherstrecke 9 ist ein Mischbecherspeicher 13 für noch nicht gefüllte Mischbecher 12 mit einem Transportband 14 vorgesehen. Ein Handhabungsgerät 15 dient zum Umsetzen eines Mischbechers 12 aus dem Mischbecherspeicher 13 auf die Wiegeeinrichtung 11 des Drehtisches 10. Dabei kann vor dem Handhabungsgerät 15 noch ein Scanner 16 angeordnet sein, der auf den Mischbechern 12 angebrachte Codierungen, welche die gewünschten Parfümmischungen angeben, ablesen kann und mit dem Steuerungsrechner 8 verbunden ist.In front of the mixing cup section 9, a mixing cup storage 13 for mixing cups 12 that have not yet been filled is provided with a conveyor belt 14. A handling device 15 is used to transfer a mixing cup 12 from the mixing cup storage 13 to the weighing device 11 of the turntable 10. In this case, a scanner 16 can also be arranged in front of the handling device 15, which can read codes on the mixing cups 12 which indicate the desired perfume mixtures and connected to the control computer 8 is.

Der Mischbecherstrecke 9 ist ein weiterer Mischbecherspeicher 17 nachgeschaltet, der zur Aufnahme von gefüllten Mischbechern 12 dient, welche vom Handhabungsgerät 15 in den Mischbecherspeicher 17 befördert werden. Dabei ist im in Fig. 2 dargestellten Ausführungsbeispiel das Transportband 14 des ersten Mischbecherspeichers 13 derart umlaufend ausgebildet, daß es auch als Transportband des zweiten Mischbecherspeichers 17 dient.The mixing cup section 9 is followed by a further mixing cup storage 17, which serves to hold filled mixing cups 12, which are conveyed into the mixing cup storage 17 by the handling device 15. In the exemplary embodiment shown in FIG. 2, the conveyor belt 14 of the first mixing cup storage 13 is designed to rotate all the way around so that it also serves as the transport belt of the second mixing cup storage 17.

Die Funktionsweise der Dosier- und Mischanlage ist die folgende:
Zunächst werden z.B. manuell eine Reihe von hintereinander angeordneten leeren Mischbechern 12 auf das Transportband 14 des Mischbecherspeichers 13 gesetzt, wobei die Mischbecherspeicher 13 mit einer Codierung versehen sein können, welche die jeweils gewünschte Mischungskennzeichnung enthält. Die Codierung des Mischbechers 12 wird dann vom Scanner 16 abgelesen und zum Steuerungsrechner 8 übertragen. Rechnergesteuert greift dann das Handhabungsgerät 15 den betreffenden Mischbecher 12 und setzt ihn vom Transportband 14 auf die Wiegeeinrichtung 11 des Drehtisches 10. Entsprechend der jeweils gewünschten Mischung wird dann der Mischbecher entlang der Mischstrecke 9 rechnergesteuert durch Verdrehen des Drehtisches 10 unter das jeweilige Auslaßdosierventil 7 des entsprechenden Vorlagebehälters 1 verfahren und durch Öffnen des Ventils 7 und Abwiegen durch die Wiegeeinrichtung 11 mit der entsprechenden Menge an jeweiliger Parfümsubstanz gefüllt. Dabei fährt der Drehtisch nacheinander die erforderlichen Auslaßdosierventile 7 der jeweiligen Vorlagebehälter 1 an.The dosing and mixing system works as follows:
First, for example, a number of empty mixing cups 12 arranged one behind the other are manually placed on the conveyor belt 14 of the mixing cup storage 13, wherein the mixing cup storage 13 can be provided with a code which contains the desired mixture identification in each case. The coding of the mixing cup 12 is then read by the scanner 16 and transmitted to the control computer 8. Computer-controlled, the handling device 15 then grips the relevant mixing bowl 12 and places it from the conveyor belt 14 onto the weighing device 11 of the turntable 10. According to the desired mixture, the mixing bowl along the mixing section 9 is then computer-controlled by rotating the turntable 10 below the respective one Move the outlet metering valve 7 of the corresponding storage container 1 and fill it with the corresponding amount of the respective perfume substance by opening the valve 7 and weighing it out by the weighing device 11. The turntable moves to the required outlet metering valves 7 of the respective storage containers 1 one after the other.

Nach einem vollständigen Durchlauf des Drehtisches um 360° ist der betreffende Mischbehälter mit der gewünschten Parfümrezeptur gefüllt und wird vom Handhabungsgerät 15 aus der Wiegeeinrichtung 11 entnommen und in den nachgeschalteten Mischbecherspeicher 17 gesetzt. Zur Füllung eines neuen Mischbechers 12 wird dann wiederum vom Handhabungsgerät 15 ein Mischbecher 12 aus dem Mischbecherspeicher 13 entnommen und in die Wiegeeinrichtung 11 des Drehtisches 10 gesetzt u.s.w.After a complete run through the turntable through 360 °, the mixing container in question is filled with the desired perfume formulation and is removed from the weighing device 11 by the handling device 15 and placed in the downstream mixing cup storage 17. In order to fill a new mixing cup 12, the handling device 15 in turn removes a mixing cup 12 from the mixing cup storage 13 and places it in the weighing device 11 of the turntable 10, etc.

Natürlich ist die Erfindung nicht auf die in der Zeichnung dargestellten Ausführungsbeispiele beschränkt. Weitere Ausgestaltungen der Erfindung sind möglich, ohne den Grundgedanken zu verlassen. So kann insbesondere die Ausgestaltung der Mischbecherstrecke und die entsprechende Anordnung der Auslaßdosierventile anders gewählt sein. Außerdem können neben dem zentralen Steuerungsrechner auch noch weitere Bedienungsrechner vorgesehen sein, durch die quasi-manuell in den Anlagenablauf eingegriffen werden kann.Of course, the invention is not limited to the exemplary embodiments shown in the drawing. Further refinements of the invention are possible without leaving the basic idea. In particular, the design of the mixing bowl section and the corresponding arrangement of the outlet metering valves can be chosen differently. In addition to the central control computer, further operating computers can also be provided, by means of which it is possible to intervene in the system sequence in a quasi-manual manner.
