Definitions
- the invention relates to a filling valve for filling flat bag packaging with inhomogeneous, essentially liquid to pasty filling material.
- Filling valves of this type basically consist of a valve head with a central outlet channel which is connected to the filling material supply and which is to be opened and closed by a piston which is adjustable in the valve head.
- Such a filling valve is known, for example, from US Pat. No. 5,822,958, with which viscous filling material is to be filled, which contains "particulate matter", ie small solid parts.
- the valve head is essentially designed as a hollow housing, the cavity of which merges at the lower end into a short outlet channel into which a piston can be pushed in and out, which is guided with its piston rod in the cavity.
- the inhomogeneous product is supplied to the outlet channel from the cavity, to which the filling material is fed through a tube adjoining the valve head, in which the rod of the piston also extends.
- Another object of the invention is to better adapt the filling valve or the valve head to the filling of flat bags, and finally another object of the invention is to ensure that the filling valve is easy to clean.
- a filling valve for this, in the combination of which the valve head is designed in cross section in the form of a flat diamond or ellipse defined by the major and much smaller secondary axis, and the outlet channel which is adapted to the diameter of the piston is extended into the valve head and with is dimensioned at least twice the length of the piston, the extended part of the channel receiving the piston in its open position, and that on both sides next to the extended outlet channel on the main axis of the diamond cross-section in the valve head at least one in the lower part of the outlet channel opening product supply channel is arranged.
- the space for the piston and the space for the product supply are kept separate in the valve head according to the invention, the latter in the form of a min. is formed at least two separate product supply channels, which makes it possible to bring the product components separately and precisely dosed only immediately before the actual valve outlet, thus ensuring that each filled product batch has the same mixing ratio.
- the cross-sectional shape of the valve head which is well adapted to the shape of the flat bag, is used in order to be able to accommodate the separate product supply channels directly in the valve head.
- the upper end region of the extended outlet channel has a piston diameter in relation to the piston somewhat larger diameter and is provided with piston guide webs.
- This extended end region is designed as a detergent supply space provided with a detergent supply connection.
- the detergent supply can also, as will be explained in more detail, take place through the piston rod.
- a hollow piston rod including a corresponding bore in the piston, is also provided in the valve according to the above-mentioned US Pat. No. 5,822,958, but is used for the passage of suitable gases so that the outlet opening of the cavity can be blown free if these have become blocked should.
- FIG. 2 shows a top view of the filling valve according to FIG. 1;
- FIG. 2A shows a plan view of a filling valve with an extended main axis
- FIG. 3 shows a longitudinal section according to FIG. 1 but in a slightly modified embodiment
- Fig. 5 shows schematically the principle of a flat bag manufacturing machine.
- FIG. 5 Such a flat bag machine is shown schematically in FIG. 5, in which the filling valve is also indicated by dashed lines.
- the flat bags 100 to be produced and filled by filling valve are formed from two film webs 101, between which the valve head 1 of the filling valve to be explained in detail is located.
- the edges 102 of the two film webs 101 are connected in a known manner by means of longitudinal sealing tools 103, the transverse sealing is carried out by means of transverse sealing jaws 104, and take-off rollers 105 ensure the timed removal of the packaging material strand 106, from which the finished and filled flat bags 100 are finally cut by means of a cutting device 107 are separated.
- the valve head 1 is held by rigid product supply lines 109 which originate from storage containers 110. If this requires the viscosity of the filling material, appropriately controlled feed pumps 113 can be arranged in the product supply lines 109.
- the dash-dotted line 111 schematically represents the piston rod for the piston 2 of the valve head 1, and 112 denotes the drive for the piston rod, which is also shown only schematically.
- the filling valve according to the invention for such a flat bag machine consists of a valve head 1 with a cross section adapted to the flat bag opening cross section, with a central outlet channel 3 which can be opened and closed by a piston 2 adjustable in the valve head 1 and which is connected to the filling material supply.
- this outlet channel 3 Oriented to the illustration according to Fig.l is this outlet channel 3, the diameter of which corresponds to that of the piston, extended into the valve head 1 for the purpose provided here.
- This extended part 3 'receives the piston 2 in the open position II and in addition to this extended outlet duct 3, at least two separate product supply ducts 4 opening into the lower part of the outlet duct 3 are arranged in the valve head 1.
- Fig. 1 the adjustment or opening and closing path of the piston 2 is designated SW, and also the piston 2 is also shown in three different positions, namely in the closed position I, in the open position II and in the cleaning position III.
- valve head 1 It is also essential for the valve head 1 that its cross-sectional design, with reference to FIGS. 2 and 2A, namely that the secondary axis NA of the valve head 1 corresponds to at least half to a maximum of a quarter of the length of the main axis HA and that the side flanks 1 'of the valve head 1 is curved and the valve head 1 is rounded at the ends of its main axis HA.
- the valve head 1 is thus ideally adapted to the flat bag cross-sectional shape, whereby it must be taken into account that the valve head 1 is at the same time also a shaping element at the inlet of the two packaging material webs 101 for them and thus also creates problematic boundary conditions for the sealing of the flat bag longitudinal edges 108.
- the two packaging material webs 101 forming the respective flat bag and enclosing the valve head 1 are indicated by dots in FIGS. 2 and 2A.
- the two product feed channels 4 there is, for example, vinegar on one side and one on the other Oil-spice mixture in an appropriately dosed amount.
- these pending components run out into the outlet channel 3 or are conveyed out under pressure by means of the aforementioned feed pumps 113, specifically in the flat bags 100 shown in FIGS. 1 to 4 only with their longitudinal edges 102, in which the valve head 1 is immersed sufficiently deep during the filling process, the flat bag being closed after filling by the transverse sealing seam 108 ′ to be applied subsequently.
- the lower end regions 4 'of the two product supply channels 4 shown in FIGS. 1 to 4 converge in the outlet direction at 25 to 45 ° into the outlet channel 3 arranged at the mouth.
- These converging end regions 4 ' are simply produced by drilling the valve head 1 from the side and then closed by suitable means 4 ".
- the possibility of cleaning is provided on the valve head 1 that the upper end region 5 of the extended outlet channel 3 is dimensioned with a somewhat larger diameter in relation to the piston diameter and is provided with piston guide webs 6 and that the extended end region 5 is provided as a flushing device provided with a detergent supply connection 7 '. medium supply space 7 is formed.
- This supply space 7 is shown in Fig.l only as a dashed extension and covering the extended end region 5 in the valve head 1.
- the piston 2 in cleaning position III is exposed on all sides in a detergent supply space 7 and is thus made accessible for all-round rinsing. If flushing is to be carried out, the piston 2 is moved into this flushing position III brought and the flushing agent supply connection 7 'is opened. Switching valves at the connections A, A of the product feed channels 4 are not particularly shown, in order to be able to rinse them if necessary.
- the upper end region 5 of the elongated outlet channel 3 is dimensioned with a somewhat larger diameter in relation to the piston diameter, is provided with piston guide webs 6 and, against the rod 2 'of the piston 2 sealed, as a detergent supply space 7 is closed to the outside, but in this case the piston rod 2' is hollow and is provided directly above the piston 2 with detergent outlet openings 8.
- the upper part of the detergent supply chamber 7 can, as shown in FIG. 3, be designed as a sealed housing 9 placed on the valve head 1, but it is also possible, as illustrated in FIG. 4, for the entire detergent supply chamber 7 in the correspondingly longer valve head 1 to accommodate.
- the design details in this regard are omitted in FIG. 4.
