Wilhelm Ludwig Kraemer, Waldkraiburg Vibratory dosing device

The invention relates to a vibration metering device with a coarse dosing channel and a fine dosing channel.

In the known vibration metering devices that are used in particular in connection with weighing devices and / or packaging machines, the coarse dosing channels and the metering chute driven separately. Of the

Drive takes place in such devices by electromechanically operating vibrators, so that both for the Grobdosierrinne as well as a vibrator each is required for the pin dosing channel. The described dosing devices work in such a way that the coarse feeder is switched off when it has delivered its delivery quantity of bulk material has, while then switched on the fine feeder to complete the amount of bulk material to be dosed will.

The known vibration metering devices are particularly due to the fact that two vibrators are required are complex and complex. The object of the invention is therefore to provide a vibration metering device to create, which can be made less v / endig compared to the conventional metering devices.

According to the invention, this object is achieved in a vibration metering device of the type mentioned at the outset solved that the Peindosierrinne is arranged connected to the Grobdosierrinne. Because of this measure is only more a vibrator is required, which actuates the coarse dosing channel and the fine dosing channel together.

A particularly simple construction of a metering device can be achieved in that the fine metering channel is arranged such that it receives the bulk material supplied from the coarse metering channel. This is just a pouring device required for feeding the fine metering channel and the coarse metering channel.

It is useful that the fine metering channel is open during the entire metering process, while at the end of the Coarse dosing the coarse dosing channel is closed, e.g. by means of appropriate dosing flaps. Because of this only needs for

In a further embodiment of the inventive concept, it can be advantageous to releasably connect the fine metering channel to the To connect coarse dosing channel. This makes it easier to clean the channels that are on them during the dosing process weaning good.

Further advantages and details of the invention are given below with reference to a drawing, which in its single Figure schematically shows a possible arrangement of the coarse metering channel and the fine metering channel of a vibration metering device shows according to the invention, explained in more detail.

In the figure, of a vibration metering device, only one coarse metering channel and designated by 1 are shown a fine metering channel labeled 2 is shown. The essential thing here is that the fine metering channel 2 is within the coarse metering channel 1 is arranged in-by, for example, the fine metering channel 2 on the bottom of the coarse dose channel 1 in a suitable manner is attached. The coarse dosing channel 1 and thus also the fine dosing channel 2 are operated by a common vibrator, which acts on the coarse metering channel 1.

From a dispensing container, not shown, the bulk material is the coarse dosing "inne 1" at its input-side end (in the figure on the right) supplied. The bulk material is still closed via the coarse metering channel 1 or the fine metering channel 2 described way a container 3 arranged below the discharge end of the channels 1 and 2, the two

The Orobdosierrinne 1 and the Peindosierrinne 2 work for dS5 Docisrsn a certain quantity? .N Schute! Jt together in the following way. Since v / uring the entire dosing process the fine metering channel is open, the bulk material stream flows through both the coarse metering channel during the coarse metering 1 as well as through the fine dosing channel 2. At the end of the coarse metering, the coarse metering channel 1 is, for example by means of the flaps / closed, so that the bulk material flow of the coarse dosing channel 1 is interrupted, while the bulk material flow for fine metering of the bulk material quantity to be metered continues to flow.

For better introduction of the bulk material flow from äer Gröbdösic-rr-inne 1 in the Feindcsierrinne 2 are in the Fine metering channel 2 the side walls in the area of the input side Ending erniedri,. ,,, so that a good breakdown of the bulk material flow is achieved in a coarse metering flow and a fine metering flow.

The delivery-side end 2a of the fine metering channel 2 protrudes the delivery end of the Grobdosierrinne 1, so that the Fine metered flow is well fed into the container 2.

The fine metering channel 2 is advantageously detachably connected to the coarse metering channel 1, so that the fine metering channel 2 can be removed from the coarse metering channel 1, whereby easy cleaning of the two channels from the bulk material that settles on the channels during the dosing process is made possible.

The vibration metering device according to the invention can be particularly advantageous in connection with weighing
