Definitions
- the invention relates to a valve for the intermittent filling of liquid to flowable-pasty products from a storage container into packaging containers, which are conveyed clocked through the filling station of a packaging machine.
- packaging containers are to be understood in particular as deep-drawn cups from a deep-drawable packaging material web, which after their filling and their closure are separated from the packaging material web individually or in groups, which the packaging machine, i.e. a so-called FFS machine, passes through in steps.
- the invention relates to the filling station of such a machine and the filling valves belonging to it.
- Such filling stations which operate in a cycle, include a product storage container, associated metering pumps and closing and opening valves which are correspondingly controlled in a cycle.
- a corresponding number of metering pumps connected to the storage container is arranged in the filling station, which in turn are connected to a corresponding number of filling mouthpieces.
- only one metering pump with associated filling mouthpiece and valve is mentioned below.
- a diaphragm valve of a known type is arranged between the storage container and the metering pump, and with regard to the sterile operation that is usually required.
- Such slide valves made of highly wear-resistant materials e.g. ceramics
- the slide of the valve according to DE-A-93 12 817 Ul has a through opening, an intermediate piece taking over the closed position and then a separate transition passage which allows the flushing liquid to pass through.
- a transition passage or transverse channel is arranged separately from the passage opening in the slide, which, when the slide is set accordingly, on the one hand for the suction of the filling material into the filling pump and on the other hand for its shut-off to the filling pump serves, in the shut-off position at the same time the passage opening the path of the filling material from the pump to the outlet mouthpiece of the valve.
- the transverse channel is not involved in the transfer of the filling material to the filling mouthpiece.
- a valve-provided flushing agent connection is provided, with which a flushing agent opening arranged approximately centrally in the bottom of the transition passage is to be brought into alignment. Flushing the filling pump, the through opening and the mouthpiece is not possible in this way.
- the object of the invention is to use the transitional passage or transverse gutter per se in the slide both for sucking in the filling material and for conveying it out to the filling mouthpiece, i.e. to dispense with the arrangement of a separate through-opening for the discharge and thus at the same time to create the prerequisite for being able to use the transverse channel for flushing a part of the filling material conveying path in further training and in the closed position of the slide.
- the plates contain channels that are aligned with one another from the metering pump to the mouthpiece, a product feed channel opening out against the slide provided with a passage channel being arranged in the pump-side plate.
- a transverse channel open to the upper plate is arranged on the pump side, with a length covering the feed channel and the channel going out from the metering pump.
- the through-channel which is open towards the lower plate, is arranged at one end of the transverse channel, starting from the bottom thereof.
- the transverse channel with its through channel is alternately on the mouth of the product feed channel and the outgoing from the dosing pump channel adjustable.
- this is a simple two-way valve, but it is a two-way valve of a special kind in that there is only a single product passage in the slide in the form of a transverse channel with a direct passage leading from it, which is open to the product supply side and to the metering pump is. Of this cross channel, only a small part is used for the product passage from the metering pump for the product passage, which takes place through the passage channel to the mouthpiece, which is open directly in the bottom of the cross channel.
- the slide is also designed to be displaceable on the other side, which takes into account the requirement that the transverse channel with its through channel directly connected to it can also be used for flushing a part of the product conveying path.
- the metering pump with its outlet opening can be arranged directly above the slide valve, it is advantageously possible with appropriate thickness dimensioning of the upper valve plate to directly integrate at least part of the metering pump in the upper plate.
- the arrangement of the detergent channel in the upper plate is preferred, since this allows the lower valve plate to be made thinner.
- the two plates and the slide can be arranged such that they can be spaced apart from one another.
- valve or the filling station according to the invention is explained in more detail below with reference to the drawing of exemplary embodiments.
- Fig.l in section and increases the valve formation at the beginning of the filling process
- FIG. 2 shows a section corresponding to FIG. 1 at the end of the delivery of the filling material
- FIG. 3 shows a section corresponding to FIG. 1 when the slide is in the position during washing
- FIG. 4 shows a section corresponding to FIG. 3 in a slightly modified embodiment
- the valve for the intermittent filling of liquid to flowable-pasty products from a storage container 1 into packaging container B, which are conveyed clocked by the filling station of a packaging machine, consists of the product conveying path PF (which leads from the storage container 1 through a metering pump 2 to the dispensing mouthpiece 3). indicated by dotted lines) arranged, clocked, adjustable closing and opening valves 4, 5 (see FIG. 7), which, however, are now and according to the invention combined to form a valve V which is formed from an adjustable slide 8 sealed between plates 6, 7.
- the plates 6, 7 contain channels 9, 10 that are aligned with one another from the metering pump 2 to the mouthpiece 3.
- a product feed channel 11 opening out against the slide 8 is arranged.
- Fig.l illustrates the start of the suction stroke of the piston 2 'of the filling pump 2
- Fig.2 illustrates the discharge of the filling material to the filling nozzle 3, the piston 2' has already reached its end position.
- valve V is shown with the associated filling material storage container 1 provided with filling material filling connection 1 ', the metering pump 2 being advantageously integrated in the upper plate 6, as indicated in a highly schematic manner.
- the position of the slide 8 with its transverse channel 12 according to FIG. 6A corresponds to the suction or filling process of the metering pump 2 (see also FIG. 1), that is to say the filling material passes from the product feed channel 11 via transverse channel 12 into the metering pump 2. If the Pump piston 2 'has reached its maximum position shown and in the filling pump the filling 6B or FIG. 2 is moved until the through opening 13 of the slide 8 is aligned with the channels 9, 10 and the filling process is thus carried out when the pump pistons 2 'are falling. After a cup B has been filled, the slide 8 is again moved to the right, ie, returned to the position shown in FIG. 5A, and the entire process is repeated for filling the respective subsequent cup in continuous operation.
- a detergent channel 14 with an opening 15 open towards the slide 8 is arranged in one of the plates 6, 7 in such a way that the transverse channel 12 in the rinsing position of the slide 8 is the connection between the product feed channel 11 and the detergent channel 14 forms (see also Fig. 4), which is provided with a flushing agent drain connection 14 '(see Fig. ⁇ C).
- the flushing agent channel 14 with its mouth 15 according to FIGS. 1, 2 and 4 is preferably arranged in the upper plate 6, as a result of which the lower plate 7 of the valve can be dimensioned much thinner.
- FIG. 6C The rinsing process is illustrated in FIG. 6C, from which initially only the storage container 1, the channel 11 and the transverse channel 12 are detected in this position.
- a suitable detergent collecting device SA for the flushing process must be provided under the plate 7, the embodiment according to FIG .6D preferred, in which the plates 6, 7 and the slide 8 are arranged such that they can be spaced apart or expanded relative to one another, which does not require any further explanation, since such apparatus-constructive measures are part of common washing and cleaning practice.
- FIG. 5 shows a section of the slide 8 in a top view from the pump side.
- the metering pump 2 arranged above it is only indicated by dash-dotted lines, the drawn position of the transverse channel 12 corresponding to that of the slide position in FIG. 5A and the broken-line position shifted to the left that according to FIG. 6B.
- the relatively long product conveying path PF in the comparative figure 7 falls away from the metering pump 2 to the simple open-close valve 5 there, which in this respect It is advantageous if a correspondingly shortened mixing section results when the product is changed.
- the advantageous development of the inclusion of the flushing medium channel 14 in one or the other plate 6, 7 eliminates the product change valve PWV shown in FIG. 5 with the associated flushing agent drainage SA.
- the adjustment of the slide 8 in the closed position, the open position and also the rinsing position is carried out by means of an actuator 20, which is only schematically indicated in FIG. 7, in a known manner, and the metering pumps 2 are actuated, for example, in time by hydraulic or pneumatic drives 21, as also in FIG 7 schematically indicated, actuated.
