Definitions
- the invention relates to a device for filling liquid or flowable contents in packages, comprising: a tank for the contents to be filled, a filling device with a filling valve, wherein the filling valve has a variable flow cross-section and is adjustable between an open position and a fully closed position, a conduit connecting the tank to the charging means, a throttle valve disposed in the conduit between the tank and the charging means, the throttle valve having a variable flow area and adjustable between a first open position and a second open position, and a Control device for controlling the filling valve and the throttle valve.
- the invention also relates to a method for filling liquid or flowable contents in packages, comprising the following steps:
- the filling of liquid contents in packaging is a task that arises in the field of packaging technology, for example in food.
- the liquid or flowable products may be, for example, foods such as milk, fruit juice, sauces or yoghurt.
- packaging for example Composite packaging with several thin layers of paper, cardboard, plastic or metal can be used.
- the filling is often carried out by apparatus having a tank for the contents to be filled and a filling device with a filling valve.
- a pipe connects the tank to the filling device.
- the tank is located higher than the filling device, so that the line is inclined and the gravity can be used for filling.
- the filling valve is opened, contents from the filling device can flow into the packages until the filling valve is closed again.
- the filling valve should be completely closable, so that a good seal is achieved and no contents accidentally from the
- valves are provided in many known devices, such as throttle valves. Throttle valves are used in particular to set and adjust the flow rate.
- An important step in the filling of the packaging is to fill the flowable or liquid products as quickly as possible in the packaging in order to achieve a fast timing and thus high volumes can.
- the filling should be done largely without spattering and foaming in order to meet the hygienic requirements and to avoid contamination on the packaging or the filling machine.
- the procedure proposed in EP 2 199 249 B1 makes it possible to achieve a clean stall without dripping when closing the filling valve, in practice it has proved disadvantageous for other reasons. Because the complete shut-off of the throttle valve with the filling valve still open leads to air bubbles in the product flow.
- the invention is therefore based on the object, the aforementioned device and previously described in more detail to design and further develop such that even at high filling speeds, a filling is largely possible without splashing and foaming.
- the device is a device for filling liquid or flowable contents in packaging.
- liquid or flowable For the liquid or flowable
- the device initially comprises a tank for the contents to be filled and a filling device with a filling valve.
- the tank is preferably arranged at least 10 cm above the filling device.
- the filling valve has a variable flow cross-section and is adjustable between an open position and a fully closed position. The flow area of the filling valve can thus be reduced to "zero.”
- the apparatus also comprises a conduit connecting the tank to the filling device and a throttle valve located in the conduit between the tank and the tank
- the contents to be filled must therefore on their way from the tank to the filling device and the filling valve, a throttle valve
- the device finally comprises a control device for controlling the filling valve and the throttle valve.
- the control device is preferably connected to the filling valve and to the throttle valve.
- control device and / or the
- Throttling valve are arranged such that the throttle valve is continuously open at least partially during the entire filling period.
- the filling period refers to the period in which the liquid contents can escape from the filling valve, ie the period between the opening of the filling valve and the closing of the filling valve. According to the invention, no complete shut-off of the throttle valve should take place within this period.
- the flow cross-section of the throttle valve should therefore be at least partially open during the entire filling period. This can be achieved in different ways: by adjusting / setting up the control device: The control device should be set up in such a way that the throttle valve is not completely closed at any time during the filling period, although this would be mechanically possible ("control technology solution”) and / or
- the throttle valve should be set up so that a complete closure of the throttle valve is not mechanically possible, for example due to a passage opening ("mechanical solution").
- An advantage of the throttle valve which is at least partially open during the entire filling period, is that the pressure surge when opening and closing the throttle valve
- Filling valve is reduced. This reduces the risk of air bubbles due to air intake and / or outgassing and stalls.
- the pressure surge can relax against the tank, so that a definable state in the product located in front of the filling valve can be adjusted and set exactly the same starting conditions before each filling cycle in the pipe space in front of the filling valve.
- control device and / or the throttle valve are set up such that the throttle valve is continuously open at least partially even outside the filling period.
- Flow cross-section of the throttle valve throughout the entire filling period is at least 3 mm 2 , in particular at least 10 mm 2 .
- Throttle valve is set, can also be filled contents with increased viscosity and / or lumpy components (eg pulp) be ensured that the throttle valve is not a complete interruption of the flow with the associated disadvantages.
- the outgassing of the contents to be filled can be excluded.
- a development of the device provides a shut-off valve, which is arranged in the line between the tank and the filling device.
- a shut-off valve which is arranged in the line between the tank and the filling device.
- Throttling valve and a shut-off valve is provided in the line, the filling of the packaging can be controlled even more flexible.
- a stepwise and particularly strong throttling without stall can be achieved by the additional valve.
- control device and / or the shut-off valve are set up such that the shut-off valve is continuously open at least partially during the entire filling period.
- the shut-off valve is continuously open at least partially during the entire filling period.
- control device should be set up in such a way that the shut-off valve is not completely closed at any time during the filling period, although this would be mechanically possible (“control-technical solution”) and / or
- shut-off valve be set up so that a complete closure of the shut-off valve is not mechanically possible, for example due to a passage opening ("mechanical solution"). It can be provided that the control device and / or the shut-off valve are set up in such a way that the shut-off valve is continuously open at least partially even outside the filling period.
- the device can be supplemented according to a further embodiment by a flow meter, which is arranged in the line between the tank and the filling device. The flow meter is used to measure the volume flow. The collected data can be used to control the filling valve and other components (eg the throttle valve). In particular, the flow meter allows the filling of different filling volumes on the same filling machine.
- the flow meter may be, for example, a mechanical
- Throttling valve and / or the shut-off valve has an actuator for adjusting the flow cross-section.
- the actuator is used to change the valve position and may, for example, an actuator (eg pneumatic) and a membrane (eg plastic) include.
- the throttle valve and / or the shut-off valve have a channel whose flow cross section is variable by the actuator, in particular completely shut off.
- the variability of the cross-sectional area of the flow cross-section can be achieved, for example, by the fact that the geometry of a channel wall is changeable - for example, by a membrane or by another displaceable closure part.
- the throttle valve and / or the shut-off valve have a passage opening whose flow cross-section through the actuator is not changeable, in particular not completely shut off. This can be achieved in that the passage opening is arranged outside the range of the moving parts of the actuator.
- the passage opening can therefore be regarded as a "bypass", which bridges the lockable areas of the valve.
- the filling valve is segmentless or segmented.
- a segmentless filling valve is understood to mean a valve that forms only a single filling jet, while a segmented filling valve is understood to mean a valve which divides the filling jet into a plurality of partial streams (for example, to change the jet shape).
- the method comprises the following steps: a) providing a device for filling liquid contents in packages with a filling valve and with a throttle valve, b) opening the filling valve c) increasing the flow cross section of the throttle valve from a first cross-sectional area to a second cross-sectional area, d)
- the method is characterized in that the throttle valve is continuously opened at least partially during the entire filling period.
- no complete shut-off of the throttle valve should take place within the filling period.
- the flow cross-section of the throttle valve should therefore be at least partially open during the entire filling period. This can be achieved, for example, in the two ways already described above
- Control solution (mechanical solution)
- mechanical solution The control device and / or the throttle valve are set up such that the throttle valve is continuously open at least partially even outside the filling period.
- step a) a device according to one of claims 1 to 10 is provided.
- the device described above is suitable in all the illustrated embodiments in a special way for carrying out the method.
- steps b) to e) take place in the sequences b-c-d-e. It can therefore be provided that initially an opening of the filling valve takes place (step b), before the flow cross-section of the throttle valve increases (step c) and is reduced again (step d). Only then should the filling valve be closed again (step e).
- the filling time is divided into several phases with different filling speed: At the beginning of the filling period is filled with low filling speed (flow cross-section of the throttle valve low), later with increased Filling speed filled (flow cross-section of the throttle valve larger) and in the last phase filling time is again filled with low filling speed (flow cross-section of the throttle valve low).
- Filling speed at the beginning of the filling period has the advantage that the filling jet starts better and smoother and generates less dynamics, in particular less foam, in the packaging.
- the reduction of the filling speed towards the end of the filling period has the advantage that fewer spatters occur.
- the method can be supplemented by the following steps: f) enlarging the flow cross-section of the shut-off valve from a first cross-sectional area to a second one
- step f) takes place before steps b) to e).
- the opening of the shut-off valve should in particular already take place before the opening of the filling valve. This has the effect that the filling when opening the filling valve directly with that allowed by the throttle valve
- step g) takes place after step d) and before step e).
- the flow cross section of the shut-off valve should therefore be reduced before the filling valve is completely closed again. This has a reduction in the filling rate in the last phase of the Filling time result.
- Another advantage is that a gentle closing and good tearing of the filling jet is achieved.

- the valve 13 shown in FIG. 6a and in FIG. 6b can be used, for example, as a throttle valve 10 and / or as a shut-off valve 11.
- the valve 13 comprises a housing 14 with an inlet 15 and with an outlet 16.
