Definitions
- the invention relates to a valve for metered filling of liquids in packaging, with a housing with feed nozzle, front mouthpiece and outlet device, with one movably driven in the housing, engageable with a valve seat and forward a valve cone and behind it a thickened central part and closing body with sealing devices on the back (see e.g. WO-A-95/26 906).
- Valves or metering valves used for this have a Housing on, in which a closing body that runs from behind over the feed connector flowed with the liquid to be filled, is moved backwards intermittently, to open the valve and then push forward to close the valve.
- a known valve achieves the outflow of the liquid Filling goods with a low exit speed with sufficiently large filling quantities, so that for For example, when filling milk, there is an undesirable amount of foam in the packaging is avoided.
- the known filling valve also fulfills another condition, namely that after closing the valve prevents undesired dripping of the liquid becomes.
- screens were previously arranged at the outlet end of the metering valve, while the known valve described at the outset end of the Mouthpiece has an outlet plate in which in the direction of the longitudinal axis of the Bores running parallel to each other, forming holes Outlet holes are arranged, the diameter of which is between 1 mm and 5 mm.
- To the rear of the exit plate, i.e. upstream from this, is up to the Valve cone of the closing body is a space in which the liquid to be filled after the Closing of the known valve is held back, inter alia, by the surface tension so that there is no dripping.
- the flow jet of the known valve is often agitated and disadvantageous has too large a surface roughness so that the jet entering the packaging entrains too much air on the side. Due to the geometry of the known valve, the filling jet contains disadvantageously also a radial flow component, through which also the emerging beam becomes restless.
- the object of the invention is therefore to design the valve of the type mentioned at the outset in such a way that that both water-like liquids and those with a fiber content without Risk of constipation can be filled in doses and at the same time without relative movements a liquid jet with little to none between the packaging and the outlet device trapped air is reached at a low exit speed.
- the thickened central part of the Closure body at its peripheral area with a wreath from itself in the direction of Longitudinal axis of the mouthpiece extending flow channels is provided which forward and open to the rear into the interior formed by the housing.
- the closing body works as in the known case by opening and closing the valve, that the valve cone lifts off its seat or is pressed against the seat.
- the flow channels are located in it intermittently moving closing body, namely in the peripheral region of its thickened Central part.
- the new valve is open towards the outlet side, i.e. there is no longer a screening surface or an exit plate, as was previously considered indispensable to prevent dripping prevent.
- dripping is largely without the action of a Prevents surface tension on the liquid under the valve seat, and preferably you make the space under or in front of the valve seat as small as possible, and you create one Reduction or elimination of unwanted dripping.
- the closing body between the Valve cone in the front and the middle part of a front cylinder and between the middle part and the rear sealing means has a rear cylinder.
- the diameter the front and rear cylinders are preferably smaller than that of the thickened one Middle part. This is in connection with the approximately cylindrical jacket-shaped side walls of the housing created spaces in front of and behind the thickened middle section, in which the liquid can move as it is forced by the geometry of the valve becomes.
- the liquid can spiral into the room behind the feed pipe be moved behind the thickened middle part, in order to then enter the flow channels.
- the space around the front cylinder which is approximately an annulus Liquid should be continued calmly, so that the flow calms down to a certain extent can.
- a desired one can be successively applied to the liquid flowing through Effects are exerted, such as the collecting and redirecting effect in the room to the rear of the thickened middle part, the laminating effect of the flow channels in the room in the area of the thickened middle part and the calming in the front room in front of the thickened middle part.
- the feed connector is attached laterally, so that the closing body its movement stroke directly in the outflow direction, i.e. in the direction of the longitudinal axis of the Mouthpiece, can perform.
- the closing body largely covers the approximately cylindrical interior of the housing.
- the Diameters of the flow channels are better known compared to the outlet openings Valves large are two to ten times, preferably three to six times. As a result, the individual flow channels become blocked in the one to be filled Fibers or particles contained in liquid are practically excluded.
- the flow channels pass through the circumference of the Flow grooves arranged radially open to the outside are arranged in the middle part of the closing body and / or radially closed through holes are formed.
- the valve according to the invention works with flow channels only in the form of radially open flow grooves from the outside; and in another embodiment good results are also achieved with a valve whose flow channels only through radially closed through holes are formed.
- the new valve works best when you have both types of Provides flow channels arranged simultaneously and side by side. For example the radially closed through holes at a small radial distance from Be arranged outer periphery of the middle part and the radially outside open flow grooves between two through holes directly on the circumferential surface.
- the flow channels in the peripheral area of the closing body act like a laminator.
- the Length of the thickened central part of the valve body can be understood as a laminator. This laminator virtually eliminates any radial component in the flow through the Flow channels moving liquid.
- the essential part of the invention is this laminator, with which both water-like Fill liquids as well as those with a fiber content or other solids is allowed. Due to the relatively large diameter of the flow channels in the Compared to the previous filling valves, not only clogging is avoided, it is avoided For the reasons explained above, the formation of a largely air-free succeeds Liquid jet with a smooth surface.
- the invention is furthermore advantageously characterized in that in the transition area between the valve plug and the front cylinder sealing surface with the valve seat in the Mouthpiece can be brought into engagement and the valve cone in a free space between the valve seat and protrudes the front outer edge of the mouthpiece.
- the closing body points from the front in the rear or in the most common vertical arrangement of the valve in the filling machines from bottom to top (against the direction of flow) behind the valve cone front cylinder, behind the middle part and behind this the rear cylinder.
- the Valve cone extends to an annular surface, which the sealing surface of the Represents closure body. Through the vertical up and down movement or the intermittent Moving the closing body forwards and backwards, this sealing surface with the Valve seat engaged in the mouthpiece or disengaged from this valve seat.
- valve cone now projects in front of the valve seat on the downstream side or in front a free space.
- This space is between the valve seat and a front one Outer edge of the mouthpiece.
- Valves are not the case, because at these ends there is always a sieve, a perforated plate or the like was arranged.
- the measures according to the invention give the teaching that the liquid to be filled is only in the flow channels, i.e. only in that Laminator, undergoes a treatment in which the radial component of the flow is eliminated.
- the measures according to the invention achieve excellent results compared to known valves Results.
- the free space in the area of the front end of the mouthpiece under or in front of the valve seat is expediently kept small according to the invention. Then that will be Dripping is negligibly small or even eliminated.
- This free space can no longer be influenced at the valve seat anyway seen short in the longitudinal direction of the mouthpiece.
- the shorter the ring-shaped Outside wall the smaller this free space.
- the wall of the Mouthpiece in front and thus the length of the free space cannot be made as short as desired.
- an optimization succeeds as soon as the spraying is eliminated.
- the free one needs bigger ones Then space not to be designed, and you can even use its inner surfaces coat or produce from a material in which the concerned Liquids drain very quickly. Then no drops can form and that Dripping stops.
- the free space between the valve seat and the front outer edge of the mouthpiece in its rear area, which is up to a quarter two thirds of the axial length lies in front of the valve seat, of a crowned cross section designed surface is formed.
- the free space is divided into a crowned part that takes up a quarter to two thirds of the total length and one about cylindrical part, which is the remaining part of the axial length of this free space between the valve seat and the outer edge of the mouthpiece.
- the spherical rear area of the free space widens in cross section from a smaller inner angle ⁇ to one larger outer angle ⁇ .
- annular tear-off edge is appropriate within the free space between the Valve seat and the front outer edge of the mouthpiece. This is set against each other by two approximately at 90 ° Surfaces formed such that the tear-off edge is annular. It is preferably approximately horizontal plane, i.e. transverse to the longitudinal axis of the mouthpiece; and at the height which separates the front cylindrical part of the free space from the rear spherical part. This ring-shaped edge ensures that the liquid flowing out is torn off. This makes the no more forward cylindrical space in terms of spray effect and the like critical.
- the invention is further advantageously designed in that the outer diameter of the thickened part of the closure body is larger than the outer diameter of the front Cylinder and both outer diameters are larger than the outer diameter of the rear cylinder.
- the outside diameter of the front cylinder both with the outlet cross section of the liquid on the valve seat and with the laminator.
- the The outer diameter of the front cylinder must not be reduced too much, otherwise the annular exit surface for the liquid would be too small.
- the said Diameter through the laminator i.e. the diameter of the flow channels, to larger ones Values limited, because the larger the outer diameter of the front cylinder, the more the area of the sum of the cross-sectional areas of the flow channels becomes smaller.
- a valve chosen has an outer diameter of 47 mm thickened middle part of the closing body selected. Its function is that in radially supplied liquid above the closure body in the space around the rear cylinder and there the liquid evenly over the entry surfaces to distribute the individual flow channels. The resulting circular line at this height the rear or rear end of the laminator area, where there is an upper one, so to speak Laminator edge results. This should also be in operation when the machine is pulled backwards The closing body does not come to lie behind or over the leading edge which the Represents lower edge or front edge of the feed connector. In the closed state of the The upper laminator edge should be a stroke length in front of or below the leading edge of the feed connector.
- the new valve works very well, i.e. in the back part next to the rear cylinder, the liquid is collected and evenly Flow channels supplied, in the flow channels in the thickened central part of the Closure body eliminates the radial component of the flow, and next to that the outgoing liquid is calmed in the front cylinder.
- the length of the thickened part of the closure body is approximately 1.5 times its outer diameter.
- the diameter of the through holes is about a tenth of the axial length of the thickened part of the closure body.
- the axial length of the thickened central part of the closure body is made it as big as possible.
- this is a practically not feasible Desire, because you can the laminator area by the structure and shape of the Do not mold the entire device and thus the housing for an unlimited period of time. So must For example, such a length remains for the calming area that the liquid Flow calmly around the front cylinder and the flow pattern calm down further can. It has been found for the laminator that its outside diameter, i.e. that of thickened middle part of the closing body, should be smaller than its length.
- the outer diameter of the rear cylinder can therefore be smaller than that of the front Be cylinders because in the rear area around the rear cylinder is not like a valve seat and thus an outflow cross section is formed at the front.
- the person skilled in the art can advantageously design the valve further in that according to the invention the length of the thickened central part of the closing body is greater than the length of the front cylinder.
- a length of the flow channels is achieved, through which the individual liquid jets emerging from the through holes merge and combine into a single beam at the bottom front. This The combined jet can then move around the front cylinder of the locking cone and forward Flush out the valve cone in a calm form (flow pattern).
- valve seat By arranging the valve seat at a distance below the thickened middle part of the closing body If the valve is closed, the entire one located under the valve seat Space emptied and free with appropriate measures, some of which are described above designed to prevent dripping. In the area of the laminator, i.e. in the area of the flow channels, no longer needs special on the surface tension of the respective liquid To be considered. Required in the thickened middle part of the closing body just a lamination effect followed by a calming area towards the bottom. This Favorable functional properties are due to relatively large flow channels Diameter reached compared to known valves. Without splashing and dripping With the new valve, fruit juices can also be dispensed in doses. The flow channels in the middle thickened part of the capping body by milling and drilling without large manufacturing costs are produced.
- a pneumatic cylinder 30 On the semi-cylindrical upper part 31, which is open to the side, of an associated, holder 7 arranged below is a pneumatic cylinder 30 with piston rod 20 attached.
- the piston rod 20 is screwed to the front or below with a screw 9, which protrudes through a slider 8 and at the same time from the rear with the neck 21st of the closure body, generally designated 3, is screwed in such a way that the Slider 8 is firmly connected to the closing body 3.
- the holder 7 encompasses the housing 1, on which a mouthpiece 2 is attached below.
- the latter is described in more detail below in connection with FIG. 3. Is dashed in this, as in FIG. 4, the longitudinal axis 16, which is aligned with the longitudinal axis of the mouthpiece 2 coincides, shown.
- the closing body 3 is in the direction of this longitudinal axis of the double arrow 26 arranged vertically up and down, from the pneumatic cylinder 30 driven.
- a feed nozzle 24 opens laterally at the top in the housing 1, where the upper, rear part of the closure body 3 is located. This is made of a rubber membrane 5 or silicone sealed.
- the slider 8 ensures a sliding movement in the bore of the holder 7.
- the holder 7 is with a nut 11 with the Screwed housing 1.
- a similar nut 12 connects the housing 1 with the Mouthpiece 2, where an O-ring 13 is clamped in between, the seat of which is aseptic Aspects is designed. So that the housing 1 and the mouthpiece 2 are sealed connected with each other.
- an O-ring 15 that the Valve against a hygiene room or sterile area arranged on the outside, for example below seals a filling machine.
- the assembly is designed so that the slide 8 is inserted into the holder 7. From underneath then the closure body 3 with the slipped, rotationally symmetrical and cup-shaped configured membrane 5 inserted upwards, the key 6 then already in the groove is inserted.
- the approach 21 at the rear end of the closing body 3 now projects upwards in a corresponding central recess of the slider 8 and is with the lower part screwed the screw 9, after which the connection with the piston rod 20 and the pneumatic drive cylinder 30 takes place.
- the membrane 5 could twist, and therefore one can enter the housing from below 1 look in and check whether the membrane 5 is correctly placed.
- the membrane 5 sits exactly and in the desired position, then the mouthpiece 2 is screwed on from below.
- the air Above and to the rear behind the membrane 5 can pass through the gap 10 on the slide 8 escape at the top so that no vacuum or overpressure in the space behind the membrane 5 can arise.
- the closing body 3 has a valve cone 32 at its lower or front end, at the expanded rear end of the front cylinder 33 connects.
- the Transition area i.e. the annular area between the valve cone 32 and the front cylinder 33 is the actual sealing surface 34, which can bear against the valve seat 35.
- the sealing surface 34 is closed by closing the valve on the Valve seat 35.
- a thickened closes to the front cylinder 33 backwards and upwards Middle part 36 of the closure body 3, in the circumferential region of which there are flow grooves 37 and through holes 38 are located.
- the latter (37 and 38) are parallel to each other and in shape of a closed wreath in small intervals next to each other and are facing downwards and open at the top rear so that the liquid can flow from top to bottom during operation.
- the rear cylinder 39 connects to the rear end of the thickened middle part 36, which is connected to the extension 21 at its rear upper end, if necessary is in one piece.
- the mouthpiece 2 shown in FIGS. 1 to 3 can be seen more clearly on the basis of FIG. 3 detect.
- the front outer edge 14 can be seen from the front to the rear or from the bottom to the top of the mouthpiece 2, which is the foremost part of the entire valve and via which also Tip of the valve cone 32 does not protrude forward.
- Backwards behind the front Outer edge 14 spans the annular outer wall 40 an enlarged, cylindrical Room 41 on the back through an annular shoulder 42 and a central, circular opening 43 is limited. Through this central opening 43 protrudes as shown in Figures 1 and 2 Valve cone 32 to the front.
- the housing 1 and the mouthpiece 2 space essentially filled. Backwards from this thickened middle part 36 closes a likewise annular rear interior 47, which is connected directly to the supply nozzle 24. It should be noted in this Connects the position of the upper laminator edge 48, which is the entry surface of the Flow channels 37, 38 defined. This upper laminator edge 48 should namely also at open valve. when the sealing surface 34 has completely lifted off the valve seat 35, no further can be moved backwards as the stroke length h ( Figure 2), namely not over the Leading edge 49 of the supply nozzle 24 also. In other words, if possible the valve as far as possible is open, i.e. the closing body 3 has been pulled back farthest upwards, the upper laminator edge 48 is approximately at the level of the leading edge 49 of the Feed port 24.
- the slider 8 is shown removed. You can see the middle one Channel 50 extending in the direction of the longitudinal axis 16 of the entire assembly in the assembled State, which coincides with the longitudinal axis of the mouthpiece 2, extends. Down in the front, this central channel 50 widens for receiving the extension 21, such as one can best see from Figures 1 and 2.
- the slider 8 can preferably consist of one Material. such as PEEK, an ester concrete with good sliding properties.
- the closing body 3 can also consist of PEEK, because this material can be very well edit, is wear-resistant and in the case of a sealing seat, it grinds.
- the Locking bodies can also be made from stainless steel.
- Figures 6 to 8 allow a detailed representation and description of the closure body 3. You can see the sections described above and some of their dimensions. So is for example the diameter of the front cylinder 33 with d, the diameter of the thickened middle part 36 with D and the diameter of the rear cylinder 39 with d ' designated. These diameters are outside diameters.
- the length of the thickened middle part is designated in Figure 6 with L, the length of the front cylinder 33 with I '.
