Definitions

  • the invention relates to a method for filling containers with a metered amount of liquid by means of a metering pump, in which a filling nozzle is arranged at the outlet of a filling pipe and a control valve arranged at the inlet of the filling pipe is opened and closed intermittently and the liquid is supplied via a buffer container.
  • the invention relates to a device for filling containers with a metered amount of liquid, and this device has a buffer container connected to a feed line and a vacuum pump, under which a control valve housing with a control valve is arranged, which has a valve located underneath, at the outlet with a Filling nozzle closable filling tube above the inlet of a connection line for a metering pump closed or connects to the buffer tank.
  • a system for filling with a metered amount of liquid without air inclusion for example milk
  • a metered amount of liquid without air inclusion for example milk
  • Filling without the inclusion of air requires various measures, in particular venting at the beginning of the filling operation, if, for example, a change has been made to a different type of pack or a different filling material.
  • milk is fed from a central distribution via a feed line to the buffer container and, controlled by valves, conveyed into a filling pipe arranged under the valves, at the exit of which the tubular milk pack to be filled is located.
  • Air can now collect in this fill tube and the invention aims to sharpen measures to remove this lust.
  • the known metering pumps generally have a piston, the pump stroke of which specifies the metered amount of liquid which is filled into the package.
  • the invention is therefore based on the object to provide a method of a system with the features mentioned above, in which the flow of production goods at the start of the filling process with incorrect filling is avoided for venting such a system; and, if possible, an exact switch-on time for the actual filling process can be specified, in which it is ensured that there are no more air pockets in the system.
  • the task also applies to the improvement of a device of such a system with the features mentioned above, which allows a time-definable method of venting, after which the filling operation can preferably be started by a simple push of a button at a time at which the operator can expect with authorization can that the system has no more air pockets.
  • this object is achieved in that a vacuum is created for venting a system and for filling without air inclusion in the filling pipe and in the buffer container while closing the filling nozzle, the control valve being opened, and this after the air has bubbled upwards the control valve is closed after an adjustable time interval.
  • the application of a vacuum to the space above the liquid level in a buffer container is used to bubble out any air pockets that are located in the buffer container or in parts of the plant below it, or to generate a greater lift force for climbing than without a vacuum. Air pockets are generally driven upward in the course of time by vibrations and the like, but due to bends in the pipe system and the like it generally takes a long time until all air inclusions are removed with great certainty.
  • the shortest possible time for expelling the air inclusions is desired. By creating the vacuum, this is surprisingly easy and easy. If the filling tube is closed at the top by the control valve mentioned, the control valve is opened for venting, so that liquid present in the filling tube can be held and at the same time air enclosed therein can rise upwards. After a period of time, this control valve is closed, any other work, including bleeding, can be done and then the production operation can begin.
  • This time interval is set based on experience and by qualified specialists. The same setting of the time interval then applies to the same system and the same filling material, so that after the completion of the development work for the new venting process, these empirical values can be used without having to consult a qualified specialist to set the time interval for each filling process.
  • the venting method can be carried out according to the invention without filling packs, so that considerable savings can be made in rejects.
  • a metering pump connected to its system area, that is to say two system branches which have to be vented, which is why the two control valves are arranged separately from one another and actuated separately from one another. In this way, one branch can be vented first and closed in this clean state and then the other branch of the system can be vented.
  • the vacuum is first generated in the buffer container, the lower control valve is closed and the upper control valve is opened; then both valves are opened at the same time; after which the upper one is closed, then the lower one is closed, the upper one is opened and finally the upper control valve is closed again while the filling nozzle remains closed all the time.
  • air inclusions can be removed with certainty after a certain time, so that a certain program is run at fixed time intervals, after the completion of which the system can be automatically signaled to start. Even inexperienced operating personnel can then start the filling operation with a simple push of a button. But that means an automatic ventilation without waste product.
  • the venting method of this type is already very well thought out, but can be improved in one more detail will.
  • a filling tube closed on the outlet side by a filling nozzle is assumed, and a liquid column which has a certain weight can be assumed above the outlet-side filling nozzle.
  • an increase in weight or an increase in the liquid column must be expected, because the expelled air is replaced by the liquid, so that a greater weight acts on the outlet filling nozzle.
  • the vacuum in the buffer container is increased when the lower control valve is opened for the first time.
  • air inclusions can be removed from the filling pipe above the outlet-side filling nozzle by opening the lower control valve for the first time, so that the weight increase begins at this moment, which is neutralized again by the increased vacuum.
  • This equalization of the pressure force on the filling nozzle at the outlet end of the filling pipe by the increased suction force of the increased vacuum is particularly expedient if a filling nozzle that closes due to the negative pressure in the filling pipe is used.
  • the increase in weight when expelling the air inclusions could otherwise cause the filling nozzle to open partially because the closing force is no longer sufficient.
  • This risk is advantageous due to the intermediate step of increasing the vacuum in the buffer container and thus above the liquid column of the filling tube and can be eliminated again with simple means.
  • the above-mentioned object is achieved according to the invention in that a lower control valve, which is separately controlled from the outside, is arranged at a distance below the upper control valve, which is positively controlled from the outside, for venting the system and for filling without air inclusion. and that the connecting line of the metering pump is connected to the control valve housing between the lower and the upper control valve.
  • the positive control acts on the one hand on the control valve and on the other hand on the drive of the vacuum pump, so that both units, the Control valve and the vacuum pump, develop their effects in the ventilation system according to a certain program.
  • the known valves described above have been controlled by the state of the adjacent flow agent, and in the case of liquid filling systems the pressure of the filling material inside the system had to overcome a spring force before the relevant valve provided with this spring could be actuated.
  • the forced control of the new valve in the ventilation device not only makes its function more reliable, so that 100% closing is ensured after the switching access has been completed (the same when opening), but the switching function is also shortened because the valves are controlled from the outside can react faster.
  • the expulsion of the air inclusions can be considerably accelerated in the manner described above. Due to the features of the venting device according to the invention, it is thus possible to vent a filling system in the shortest possible time, so that the operator of the filling system can bring the system into the normal operating state without air pockets in an optimally short time.
  • the metering pump located in one of two operating branches of the system arranged below the buffer tank is independent and / or simultaneous due to the upper, separately externally positively controlled control valve arranged at a distance above the lower control valve and the connection of the metering pump to the control valve housing between the lower and the upper control valve vent with the fill pipe in the desired manner.
  • the filling nozzle consists of an elastomeric material.
  • a rubber filling nozzle can be used which, when closed, has two cross-shaped slots which are kept closed by the negative pressure located behind it inside the filling tube.
  • Such a rubber nozzle has the natural tendency to close, which is why a low vacuum in the tube above the rubber nozzle relative to the outside atmosphere is sufficient to close or keep the nozzle closed.
  • a liquid column can be held in a completely closed filling tube above the closed nozzle without the risk of dripping.
  • the use of such a rubber nozzle in a venting device of the type described here has hitherto not been known.
  • control valves and / or the vacuum pump are connected to a computer control, the advantages of rapid and reliable ventilation described above can be achieved. It is state of the art today to feed simple or complicated programs into a computer which can output control signals in a time-controlled manner with great accuracy, so that the venting method described here can be carried out in a precisely timed manner with great reliability.
  • FIG. 5 where on the schematically arranged conveyor belt 1 there is a liquid pack open on one side at the top 2, the lower end of a filling tube 4, which is closed with a filling nozzle 3 made of rubber.
  • the filling nozzle 3 is shown largely immersed in the pack 2. It can be provided in a suitable system for filling paper packs with a metered amount of milk, a relative movement between the filling tube 4 and the pack 2, so that when the pack is empty, the filling nozzle 3 almost reaches the bottom of the pack 2 and here the filling process during slowly pulling the filling tube 4 out of the pack 2. Since the filling process as such is not important for the explanation of the process steps and device features of interest here, the above description of the filling should suffice.
  • a control valve housing 6 On the inlet side 5 of the filling pipe opposite the outlet of the filling pipe 4 with the filling nozzle 3, connected upwards, a control valve housing 6 is provided, which is designed in the form of a cylinder jacket with a side opening 7, from which the connecting line 8 of a metering pump 9 is branched, namely from a space 10 above the seat 11 of the lower control valve 11 'and under the valve seat 12 of the upper control valve 12'.
  • Both control valves 11 'and 12' are shown closed in the state of Figure 5. In addition, they appear highly schematic with the actuating rods protruding outside the control valve housing 6, which are only intended to symbolically illustrate the positive control of the control valves 11 ', 12' from the outside.
  • a buffer tank 13 which is provided on one side (bottom left here) with a feed line 14 and on the other side (top right here) with a vacuum line 15 and a vacuum pump 16.
  • the black space 18 arranged above the corrugated dividing line 20 above the liquid mass 17 with the gas-tightly closed lid 19 of the buffer container 13 represents the vacuum.
  • the venting device works with the two at a distance a control valves 11 'and 12' arranged one above the other as follows: It is assumed that below the level 20 of the liquid 17, the entire system, including the metering pump 9, is filled with the liquid to be filled at the start of a production operation. Trapped air must now be expelled as follows.
  • the buffer container 13 is evacuated via the vacuum pump 16, so that a first specific vacuum is established in the space 18. It is understood that above the closed upper control valve 12 'trapped air is withdrawn through this vacuum through the vacuum line 15. It is assumed that the state in FIG. 5 is assumed, a partial vacuum also being generated in the space of the filling tube 4, by means of which the filling nozzle 3 is closed.
  • the pack 2 is no longer shown in the further FIGS. 1 to 4, and the buffer container 13 is also broken off at the top. During the entire operational sequence in the venting according to FIGS. 1 to 5, the filling nozzle 3 is to be regarded as closed.
  • FIG. 1 After the vacuum in room 18 has been set, the state of FIG. 1 is switched to, i.e. the upper control valve 12 'is opened. Air inclusions located in the area of the metering pump 9 can now be removed upward into the buffer container 13 in the direction of the arrows 21. The liquid column located above the piston of the metering pump 9 is therefore also under the vacuum shown. The first subspace, i.e. the left branch of the venting device with the connecting line 8 is thus vented.
  • the vacuum pump 16 is switched on after a special part of the computer program in order to set the level of the vacuum in the room 18 to an increased value.
  • the filling nozzle 3 made of rubber remains closed, although the suction of small amounts of gas (air) from below into the filling pipe 4 cannot be completely ruled out, although there is no leak-tightness. This air bubbled in from below also migrates upwards according to the paths shown by the arrows 22.
