Definitions

  • the invention relates to a filling valve for a container filling machine, in particular for filling drinks into containers such as bottles, cans and the like under counterpressure, the filling valve being a gas pipe which can be raised and lowered within a valve closing body and a centering bell which can be raised and lowered independently of this for sealing the container mouth from the ambient atmosphere and the control movement of the valve or the movable valve parts can be initiated at least partially by a rotary pinion which can be actuated outside the boiler receiving the filling valves and has switching cams.
  • Such a filling valve is known for example from DE-OS 2 126 113.
  • This is a valve for filling beverage cans, the liquid to be filled being under pressure and a corresponding counterpressure also being built up in the can to be filled.
  • the can is preloaded with the pressure prevailing in the boiler and, after the pressure has been equalized, the actual filling valve is opened so that the liquid in the boiler can flow into the can using the geodetic gradient.
  • the liquid rises during the filling process to the lower opening of the return gas pipe, whereupon the further filling process stops automatically because no return gas exchange from the container or the can can take place back into the boiler. This is followed by the pressure relief of the can, which is then removed from the filling valve and closed.
  • a centering bell is provided to seal the can on the filling element a differential pressure chamber works, with which the tulip seal is pressed against the container mouth during the filling process.
  • the gas pipe is movably guided within the filling valve body.
  • it has a rigid connection to the centering bell, so that the gas pipe end always protrudes a certain distance above the lower edge of the centering bell according to the desired filling height.
  • the lifting movement of the centering tulip must be designed to be larger by at least this protruding gas pipe piece, so that a certain amount of space remains between the tulip or the gas pipe bottom edge and the top of the box during the insertion of the box under the centering bell or under the filling element. This leads to an undesirable large relief volume.
  • the invention has for its object to achieve an improvement in the design and a simplified control of the valve while avoiding a piston-cylinder arrangement.
  • a filling valve of the type mentioned in that a first spring is provided which stretches the gas pipe and the valve closing body from one another at a distance, the gas pipe abutting an upper stop of the valve closing body in that a second spring with a stronger spring is on the valve closing body Bias is present than that of the first spring and that when the switch cam is turned downward, the gas pipe is released and brought into its lower end position by the first spring, the valve closing body remaining in the closed position and by the action of the switch cam on the second spring against the force of the first spring can be brought into the open position.
  • valve closing body is held in the closed position by the internal pressure of the boiler acting on a sealing body of the gas pipe via a stop connection which acts against the force of a spring by means of the gas pipe.
  • the filling valve according to the invention has significant advantages in the course of the control processes. This means that there is no need to individually control the valves if the container is missing, since the valve closing body cannot be opened if the container is missing. Furthermore, the predetermined upper and lower stops give exact positions of the individual parts of the filling valve individually as well as to one another. Furthermore, a substantially improved cleaning of the entire filling valve in the circulation system can be carried out by switching off a piston-cylinder arrangement. In addition, the springs required for control are arranged above the boiler filling level.
  • filling valves 1 are arranged in a circular order on an annular bowl 2 of a rotating filling machine (not shown further).
  • the filling valve 1 consists of a lower housing 3, on which a centering bell with a pressure seal 4 can be raised and lowered.
  • the housing 3 receives a flushing valve 5, which can be opened one or more times by control tracks 6 in accordance with the desired procedure.
  • the valve closing body 8 has a tubular extension 10 which extends into the upper space 11 of the ring bowl 2 and can be moved into the open position by means of a pressure sleeve 12 and a control cam 13 of a control pinion 14 which can be placed thereon.
  • the gas pipe 15 is arranged inside the valve closing body 8 and in the extension 10. This has a thickening 16 in its central region, which can also be provided as a plastic bushing for guiding the extension 10.
  • the lower end 17 of a first spring 18 is supported on this thickening 16. The upper end of this spring 18 rests on an inner ring 19 of the extension 10 of the valve closing body 8. In this way, the valve closing body 8 and the gas pipe 15 are braced against each other.
  • the spring 18 also supports the contact pressure effect due to the difference in area between the gas pipe body and valve closing body 8 after prestressing the container. In this way, the valve closing body 8 remains in the closed position even when the biasing valve 24 is open.
  • the extension 10 is mutually preloaded of the valve closing body 8 with the gas pipe 15, webs 21 rest on appropriately designed webs 22 of the extension 10. As a result, the valve closing body 8 is held in the closed position.
  • a sealing body 23 is arranged, which is brought into the upper position by the control cam 13 of the control pinion 14 and is held by the boiler overpressure.
  • a container 28 is first moved through feed stars or the like under the ring bowl and the filling valve 1 located in the inlet area. Immediately afterwards, the centering bell 4 with its contact seal is lowered onto the mouth of the container 28 by guide rollers and cam tracks (not shown). As soon as the sealing has taken place, the actual filling process can be started.
  • the biasing valve 24 is first actuated by the control track 36, so that a short circuit with the boiler gas or a separate fresh gas, the purging process is initiated with the purge valve 5 open. If this is considered necessary, a corresponding evacuation of the container interior or a corresponding disinfection, steam sterilization or the like can also be carried out.
  • the switching cam 13 By further actuation of the rotary pinion 14, the switching cam 13 reaches the upper end face of the pressure sleeve 12, which then acts on the outer spring 25 and, contrary to the inner spring 18, causes the filling valve to open immediately because the outer spring 25 is more pretensioned than the inner one Has spring 18.
  • the gas pipe end 31 is in its lower position, which is also responsible for determining the fill level in the container 28.
  • the switching cam 13 still performs a slight overstroke and remains in this position.
  • the liquid in the ring bowl 2 now flows under the influence of geodesic gradient in the container 28 and reaches the lower end face 31 of the gas pipe 15, whereby a further gas exchange is no longer possible and in this way the final filling level is reached.
  • the switching cam 13 of the rotary pinion 14 is moved up again, whereby the closing process for the valve closing body 8 is automatically initiated when the pressure sleeve 12 is relieved by the inner spring 18.
  • the pressure sleeve 12 moves with its stop edge against the stop ring 27, so that the outer spring 25 becomes ineffective and the inner spring 18 exerts the closing process of the valve closing body 8 when the gas pipe 15 is still in the lower stop position.
  • the upper region of the switching cam 13 lies against the lower end face of the sealing body 23 and thus also moves the gas pipe 15 to the stop 22 of the extension 10 of the valve closing body 8 and thus into the upper stop position.
  • the seal 32 lies against the inner end face of the interior of the boiler and at the same time creates a connection to the preload valve 24.
  • the flushing valve 5 By opening the flushing valve 5, the interior of the container above the liquid level is then relieved and the filled container is removed from the filling machine after the centering bell 4 has been raised.
  • the annular chamber can be arranged at a certain distance from the annular bowl (2) by insulating means in order to exclude heat transfer to the latter or the filling material.
