Description

Die Blitzlampe 9 wird über das Kabel 10 mit normaler Netzspannung versorgt, welche beispielsweise durch einen Transformator auf die erforderliche Arbeitsspannung transformiert wird. Auf die Batterie 7 und den Impulsverstärker 8 kann auch verzichtet werden, wenn der Impulsgeber 6 so ausgelegt wird, daß er eine genügend hohe Zündspannung liefert, welche die Blitzlampe 9 direkt zur Auslösung bringt. An Stelle des Kontaktes bzw. Impulsgebers 6 können auch Lichtschranken mit Photodioden oder andere bekannte elektronische Impulsgeber zur Anwendung gelangen. Diese können von jedem beliebigen drehenden Teil der Malvorrichtung gesteuert werden. Falls keine hohe Anforderung an die Lichtstärke gestellt wird, kann der Impulsgeber 6 so ausgelegt werden, daß dieser ohne Zwischenverstärker eine Blitzlampe speist und diese im richtigen Moment zum Aufleuch- The flash lamp 9 is via the cable 10 with normal mains voltage supplied, which for example by a transformer to the required Working voltage is transformed. To the battery 7 and the pulse amplifier 8 can also be omitted if the pulse generator 6 is designed so that it a sufficiently high ignition voltage supplies which the flash lamp 9 is triggered directly brings. Instead of the contact or pulse generator 6, light barriers can also be used Photodiodes or other known electronic pulse generators are used. These can be controlled from any rotating part of the painting device. If there are no high demands on the light intensity, the pulse generator can 6 can be designed so that it feeds a flash lamp without an intermediate amplifier and this at the right moment to light up

Da der Blitzimpuls der Lampe 9 auf mechanischelektronischem Wege mit der Drehzahl des Auflagetelzers 2 und damit der Malfläche3 synchronisiert ist, wird die Malfläche 3 nur jeweils in einer bestimmten Lage während einer Umdrehung kurzzeitig angeleuchtet, so daß durch die schnelle Lichtimpulsfolge der Eindruck für den Betrachter entsteht, als ob die Malfläche sich in einem ruhenden Zustand befindet. Since the flash pulse of the lamp 9 mechanically-electronically is synchronized with the speed of the support plate 2 and thus the painting surface 3, the painting surface 3 is only in a certain position during one revolution briefly illuminated, so that the impression is made by the rapid light pulse sequence for the viewer it appears as if the painting surface is in a state of rest is located.

Auf diese Weise kann das durch die Fliehkraft bewirkte Verteilen der Farbmasse vom Malenden in allen Einzelheiten und in allen Bewegungsphasen beobachtet werden, und die Drehung der Malfläche 3 kann in jedem gewünschten Augenblick abgebremst werden.In this way, the centrifugal force can distribute the Paint mass observed by the painter in all details and in all phases of movement and the rotation of the painting surface 3 can be slowed down at any desired moment will.

In F i g. 2 ist die gleiche Vorrichtung ebenfalls in perspektivischer Ansicht dargestellt, wobei die Lichtquelle durch eine ständig leuchtende Lampe 12 gebildet wird. Um einen kurzzeitigen Lichtimpuls zu erzielen. ist die Lampe 12 durch einen rotierenden Schirm 13 abgeschirmt, und nur in dem Augenblick, wenn der in dem Schirm 13 befindliche Schlitz 14 sich vor der Lampe 12 in Richtung auf die Malfläche befindet, entsteht ein Lichtblitz, der die Malfläche bei jeder Umdrehung - oder auch jeweils nach mehreren Umdrehungen - in einer bestimmten jeweils etwa gleichen Lage kurzzeitig anleuchtet. Über die Welle 15 und dei Treibriemen 16 ist die rotierende Abschirmvorrich tung 13 mit der Drehzahl des Motors 17 bzw. mit de Drehzahl der Mal fläche genau synchronisiert. De: Lichtimpuls einer ständig leuchtenden Lampe kanr natürlich auch durch oszillierende Schlizverschlüsse oder Irisblenden od. dgl. erzeugt werden, wobei je weils eine genaue Synchronisation mit der Drehzahl der Malfläche gewährleistet sein muß. Um den Leucht effekt der Lampe 12 zu verstärken, kann vor und hinter dem Schlitz 14 eine optische Linse angebracht werden, wobei der Lichtstrahlengang so gewählt wird, daß der Brennpunkt der an der Lampenseite liegenden Linse genau in die Ebene des umlaufenden Schlitzes fällt. Diese Linse kann dabei auch so gewählt werden daß eine zweite außerhalb des Schirmes 13 nicht erforderlich ist. Es kann auch eine elektronische Steuerung der mechanisch oszillierenden Abschirmvorrichtung für die ständig leuchtende Lampe herangezogen werden. Dabei wird dann so vorgegangen, daß der Impulsgeber an der Motorwelle oder an einem anderen drehenden Teil der rotierenden Malvorrichtung einen Stromimpuls liefert, welcher beispielsweise einen Schaltmagneten bewegt, welcher seinerseits wiederum den mechanischen Abschirmmechanismus vor der Lampe in eine synchron zum Malgerät laufende oszillierene Bewegung versetzt. In Fig. 2 is the same device also in perspective View shown, the light source being a continuously lit lamp 12 is formed. To achieve a brief pulse of light. the lamp 12 is through a rotating screen 13 is shielded, and only at the moment when the in The slot 14 located on the screen 13 is in front of the lamp 12 in the direction of the painting surface is located, there is a flash of light that touches the painting surface with every turn - or also after several revolutions - in each case approximately the same in a certain one location briefly lights up. About the shaft 15 and the drive belt 16 is the rotating Shielding device 13 with the speed of the motor 17 or with the speed of the Times surface exactly synchronized. De: light pulse from a constantly glowing lamp Can of course also by oscillating Schliz fasteners or iris diaphragms or the like. are generated, each Weil an exact synchronization with the speed of the Painting surface must be guaranteed. To increase the lighting effect of the lamp 12, an optical lens can be attached in front of and behind the slot 14, wherein the light beam path is chosen so that the focal point on the lamp side lying lens falls exactly in the plane of the circumferential slit. This lens can also be chosen so that a second outside of the screen 13 is not is required. There can also be an electronic control of the mechanically oscillating Shielding device can be used for the constantly glowing lamp. Included the procedure is then that the pulse generator on the motor shaft or on another rotating part of the rotating painting device delivers a current pulse, which for example, moves a solenoid, which in turn moves the mechanical Shielding mechanism in front of the lamp in an oscillating synchronous to the painting device Movement.

Claims

Claims: 1. Device for producing color compositions on a painting surface that rests on a rotatably drivable holding device, whereby the color mass applied to the painting surface during its rotation due to the occurring centrifugal forces with involuntary formation of certain forms on the Paint surface is distributed, d a -characterized in that a light pulse on the Light source emitting painting surface is provided and that the speed of the painting surface is synchronized with the light pulse train.

2. Apparatus according to claim 1, characterized in that the light source as a flash lamp or as an illuminated, rotating or moving reflector is trained.

The invention relates to a device for producing color compositions on a painting surface that rests on a rotatably drivable holding device, whereby the color mass applied to the painting surface during its rotation due to the occurring centrifugal forces with involuntary formation of certain forms on the Painting surface is distributed.

Here it is necessary that the painter should do as good a work as possible Exercise control over the current state of the color distribution on the painting surface can.

It is known to use the device to meet this control option to be provided with a switching mechanism which allows the painting surface to be relatively to bring them to a standstill briefly to control how far and in which The applied color mass has already spread over the painting surface. The disadvantage of this type of control and the way of operating such a device consists in starting the rotating painting surface and braking it is a relatively slow process, so that the end of the painting is spreading the applied Can only control paint mass poorly or not at all. To this comes that through the different strong centrifugal forces depending on the speed of the painting surface the speed the color distribution varies greatly. This fact also makes it difficult to control about the respective state of the color distribution, so that the end result of the color composition is more or less left to chance.

The invention is therefore based on the object of a device to create, which makes it possible to distribute the color on the painting surface and thus So the picture to be painted is always flawless - even while the painting surface is being rotated to be able to control.

This object is achieved according to the invention in that a light pulse on the painting surface emitting light source is provided and that the speed of the The painting surface is synchronized with the light pulse train. The light source can as a flash lamp or as an illuminated, rotating or moving reflector be trained.

The synchronization between the rotating the painting surface and the Light pulse sequence can be achieved that the rotating painting surface like a sharp drawn still picture appears, eliminating any change on the painting surface can be observed and followed in all phases after application of the color composition. Electrical and / or mechanical synchronizations for flash lamps, flashing light sources or reflectors generating light pulses are known and do not need any further details here to be described.

The advantages that can be achieved with the invention are in particular in that the process of color distribution by the viewer at any time, including during the rapid rotation of the painting surface, can be controlled. The user of the Painting device is thus always on the progress of the picture area distributing color mass and above all about the emergence of currently emerging of original shapes oriented on the painting surface, so that the rotational movement of the painting surface can be changed or slowed down at the right moment.

This allows the quality and diversity of the to be painted Color compositions decide to be improved. This also applies to the painting of uneven surfaces, such as those of Fellern or other bodies with spherical ones or curved surfaces.
