The rotatable holder is characterized in that a movable transfer element is arranged by means of which the metering valve can be moved back and forth between the annular holder and the center of the annular holder.

This design requires only one transfer element that can be placed by a rotatable holder opposite each of the metering valves and that can engage the metering valves, and furthermore, it is simple without the use of rotating parts. The design allows the metering valve to be fixed in the annular holder.

The rotatable holder preferably comprises an arm extending radially towards the vicinity of the fixed annular holder;
The transfer element is movable radially on the arm, so the design of the transfer element is very! Ii is pure.

The rotatable holter is also conveniently provided with a cleaning stage for the metering valves, thus requiring only one cleaning element that can be transported continuously along the entire metering valve. The gold valve can be cleaned after a predetermined period of time, while there is no need to disassemble any part of the device or remove the valve.

The cleaning element is preferably for a rotatable porter j)
) is movable in the vertical direction and is movable towards the bottom of the cleaning↑1M displacement J<lube, so cleaning can be limited to the required areas.

The shape of the −L side of the 119 element is conveniently configured to match the shape of the lower side of the metering valve.

In a preferred embodiment, the cleaning element is oriented laterally from a collection hopper which is arranged in the χ·1 direction below the metering valve, the hopper having at least one −V-oriented jet; Is each spray head compressed air? 11'-Liquid with or without gargling; h Connected to a conduit for containing the sinking agent, and the collection popper is provided with an outlet.

In order to operate the cleaning element more or less independently, the cleaning element is arranged so as to form an angle to the transfer element when viewed in the plane of rotation of the rotatable holder. .

The invention will now be explained in more detail with reference to the accompanying drawings, in which: FIG.

The metering device shown in FIG. 1 consists of a frame 1 to which an annular holder 2 for supporting a plurality of metering valves 3 is attached.

The annular holder 2 is fixed. The metering valves 3 are removably arranged on the fixed holder 2 and arranged around the circumference. Each metering valve 3 is connected to a flexible conduit 4 for supplying the component to be metered. The line consists in this case of two flexible hoses connected to a pump (not shown).

A holder 5 rotatable with respect to the frame 1 is disposed inside the annular fixed holder 2. The rotation axis of the 0-rotatable holder 5 coincides with the axis of the fixed holder 2. The rotatable holder 5 is fixed to a hollow drive shaft 7 which is rotatably mounted to the frame 1 via bearings 8 and can be driven by a motor 9 via a transmission 10.

The rotating holder 5 consists of an arm 11 extending radially towards the vicinity of the fixed annular holder 2, on which a radially movable transfer element 12 is arranged. There is. This transfer element 12 can be placed opposite the metering valve and can grip it and move it into the center of the annular holder 2 .

At the end of the transfer element 12 there is provided a gripping element 13 which grips the valve 3 once and is actuated, for example, by a hydraulic or pneumatic cylinder 14 .

At the center of the fixed holder 2, there is a control device for moving the Ji quantity valve placed in the center by one stroke, i! 16 are set. This device is driven by a hydraulic or pneumatic cylinder 17 mounted, for example, on the frame 1, which controls the metering valve to discharge a specified amount of a component of the composition into a reservoir 18 located below the metering valve. Open and close. The tank 18 is arranged above the weighing scale 9 in FIG.

The operation of the entire system will be briefly explained below.

When a particular quantity of a component of the composition is to be metered, the transfer element is placed by means of a rotatable holder 5 opposite the corresponding metering valve 3. The transfer element 12 grips the metering valve, which is placed below the control device 16 and a quantity of the component is charged into the reservoir 18, after which the metering valve returns to its position on the fixed holder 2. Its descendant, transfer element 12, is rotatable to the next metering valve to meter the next component.

As is clear from the above description, the transfer element for reciprocating between the fixed holder and the center of the holder is relatively simple and includes only one transfer element that can be used for all metering valves.

During operation of the device, the underside of the metering valve must be periodically cleaned.

For this purpose, in addition to the transfer element 12, a cleaning element 20 is mounted on the rotatable holder 5 for cleaning the outside, in particular the underside, of the metering valve 3. The cleaning element also includes:
It can be arranged opposite each of the metering valves 3 for cleaning each of the metering valves.
