Definitions

  • the invention relates to a vessel filling machine according to the preamble of claim 1.
  • Such a vessel filling machine is already known, in which the tensioning gas valve is arranged above the liquid level in the storage container and its valve body has a downward, tubular extension which penetrates the center of the outlet opening and protrudes therefrom.
  • the probe is adjustably fastened in the valve body or its extension to form an annular space which is open at the bottom and at the upper end of which a throttled discharge line which leads to the outside is provided for the return gas displaced from the vessel when it is being filled (DE-OS 2 007 896) .
  • the filling element of this known vessel filling machine has a variety of difficult to clean and compressible Gas pockets filled cavities that lead to disturbing pressure surges during the filling process, especially when relieving.
  • the manufacture of the filling element is complex and, because of the many components protruding into the vessel, only vessels with a wide mouth can be filled.
  • the invention has for its object to noticeably improve a vessel filling machine of the type mentioned in terms of filling accuracy, area of application, possibility of cleaning and manufacturing costs.
  • the vessel filling machine shown is set up for filling bottles 1 with a carbonated beverage, for example beer, at a superatmospheric counterpressure. It has an annular, closed storage container 2 with an essentially rectangular cross section, which rotates around its vertical central axis 3.
  • the reservoir 2 is up to level 4 with the drink and above it with a tension gas in the form of a high-proof CO 2 -air mixture with an overpressure of, for example, three bar.
  • the beverage and the tensioning gas are supplied in the usual way by radial pipes, rotary distributors, regulating devices, etc., not shown.
  • a large number of identical filling elements 5 are arranged on the storage container 2, evenly distributed over the circumference, each of which is assigned a controllable lifting element 6 for the bottles 1 and a controllable centering bell 7 for the bottle mouth.
  • Each filling element 5 has a valve block 8 fastened to the underside of the storage container 2, on the underside of which a vertical, cylindrical outlet opening 9 for the liquid is formed.
  • the outlet opening 9 goes upwards via a conical valve seat 10 into an enlarged vertical bore 11, which in turn adjoins a vertical bore 12 formed in the bottom of the storage container 2.
  • a piece of pipe 14 is provided with a plurality of longitudinal slots 13, which is aligned with the bore 11 and projects through the bore 12.
  • the pipe section 14 ends above the level 4 and is equipped at the upper end with inwardly directed guide bolts 15 for a vertically standing, vertically movable valve body 16.
  • the valve body 16 is tapered at the lower end and provided with a sealing ring which is connected to the valve seat 10 cooperates.
  • the valve body 16 thus forms, together with the valve seat 10, the liquid valve 17 of the filling element 5. If the valve body 16 is lowered, as shown on the left side of the drawing, no liquid can escape from the outlet opening 9. If the valve body 16 is raised, as shown on the right side of the drawing, the liquid from the reservoir 2 through the slots 13 and the annular space between the pipe section 14 and the valve body 16 and through the bores 12 and 11 largely unimpeded and streamlined to the outlet opening 9 and through it into a bottle 1 pressed against the filling element 5 with the interposition of the centering bell 7.
  • the opening position is defined by the contact between guide pins 18, which are fastened to the valve body 16 and loosely center them in the bore 11, and an annular stop 19 formed on the valve block 8 at the upper end of the bore 11.
  • the valve body 16 has a through bore which narrows conically at the lower end directly above the liquid valve 17 to form a further valve seat 20.
  • the valve seat 20 interacts with a vertical, vertically movable further valve body 21 and forms with it the tensioning gas valve 22 of the filling element 5.
  • the valve body 21 is essentially tubular, its outer diameter being substantially smaller than the inner diameter of the valve body 16, in the bore of which it is concentric is arranged.
  • the valve body 21 has a thickening 23, which on the Underside carries a sealing ring cooperating with the valve seat 20.
  • the thickening 23 is provided on the jacket with a plurality of guide ribs 24, through which the valve body 21 is guided in the valve body 16 so as to be vertically movable.
  • a return gas tube 25 Downstream of the valve seat 20 is a return gas tube 25, which is detachably fastened in the lower end of the valve body 16 and projects freely downward concentrically through the outlet opening 9, forming an annular space for the liquid.
  • the return gas pipe 25 is provided at the lower end with a screen for the liquid, protrudes from the underside of the valve block 8 and projects into the head space of a bottle 1 pressed against the filling element 8 during the filling process. It leads on the one hand with its screen from the outlet opening 9 escaping liquid to the inner wall of the bottle 1 and also allows the supply or discharge of clamping gas from the reservoir 2 in or out of the bottle 1. If the valve body 21 is lowered, as shown on the left side of the drawing, is the Passage blocked for span gas. If the valve body 21 is raised, as shown on the right-hand side of the drawing, then a connection is established between the tension gas chamber of the storage container 2 and the interior of a bottle 1 via the bore of the valve body 16 and the return gas pipe 25.
  • the valve body 21 is extended upwards relative to the valve body 16 and can be moved by a guide bushing 26 fastened in the cover of the storage container 2 led out of this.
  • the passage is sealed off in a gas-tight and liquid-tight manner by an elastic bellows 27 attached to the valve body 21 on the one hand and to the guide bush 26 on the other hand.
  • a bracket 28 is attached to the end of the valve body 21 projecting upward from the reservoir 2, which bracket is in turn attached to the piston rod of a single-acting pneumatic cylinder 29.
  • the latter is rigidly connected to the guide bush 26.
  • a compression spring 30 which surrounds the valve body 21 and which attempts to move the valve body 21 into its upper, open position is inserted between the bracket 28 and the guide bush 26.
  • the valve body 21 is penetrated over its entire length without the formation of cavities by a rod-shaped probe 31, the outside diameter of which corresponds to the inside diameter of the valve body 21.
  • the probe 31 thus projects into the neck space of a bottle 1 pressed against the filling element 5 approximately to the region of the desired filling level.
  • the upper end of the probe 31 protrudes from the valve body 21 and is adjustably fixed relative to the valve body 21 by means of a clamping piece 32.
  • the probe 31 thus makes the normal stroke movement of the valve body 21 of the gas valve 22, which is caused by the pneumatic cylinder 29, to the full extent With.
  • a measuring cable 34 is connected to the upper end of the probe 31 by means of a plug 33, which leads to an electronic control device 35.
  • this controls exclusively the pneumatic cylinders 29 and thus the liquid valves 17 and the tensioning gas valves 22 in cooperation with compression springs 36 which are inserted between the guide bolts 15 on the one hand and the bent upper end of the valve body 16 on the other hand.
  • the valve body 21 is pressed directly downward against the valve seat 20 against the force of the compression spring 30 via the bracket 28; the span gas valve 22 is thus closed.
  • the valve body 16 is pressed down against the force of the compression spring 36 against the valve seat 10; the liquid valve 17 is thus also closed.
  • the filling element 5 assumes this state at the end of a filling process or between two filling processes.
  • the bracket 28 and thus the valve body 21 is pressed into its upper end position by the force of the compression spring 30; the span gas valve 22 is thus open.
  • the liquid valve 17 initially remains closed under the influence of the excess pressure in the reservoir 2. Only when the pressure has been equalized by the tension gas flowing into the bottle 1 via the tension gas valve 22 and the return gas tube 25, is the valve body 16 also raised by the compression spring 36; the liquid valve 17 is thus open.
  • the liquid can then enter the bottle 1 via the liquid valve 17 and the outlet opening 9.
  • the lower measuring or end area of the probe 31 which is designed, for example, as a conductivity or short-circuit probe, the latter sends a signal to the control device 35 via the measuring line 34. This triggers the air supply to the pneumatic cylinder 29 immediately or after an adjustable delay time. whereby the liquid valve 17 and the span gas valve 22 are closed together. Bottle 1 is filled exactly to the desired level.
  • a relief channel 37 which opens obliquely downwards into the outlet opening 9 is formed in the valve block 8.
  • the ring line 40 serves to return the cleaning liquid supplied via the reservoir 2 in a closed circuit.
  • further channels and control valves for example for vacuum, opening into the outlet opening 9 can be arranged.
