Abstract
In a bag-filling connection for filling upwardly open bags with dusty products a pre-storage space (4) is provided in the space inside the spreader flaps (6), extends to the region of the edge of the mouth opening of the bag, is formed from shaped members (17, 18) or a flexible tube, and has its lower end dust-tightly closed by the closing movement of spreader flaps (6). The end walls of the pre-storage space (4) are at a spacing from rubber skirts which are fixed to the ends of the spreader flaps (6). The bag (3) is held by the spreader flaps (6) and clamping jaws (5). Each of the chambers formed is in communication with a suction nozzle (1) and the suction can be controlled by a flap (16, Figure 5, not shown) which is movable between an open position and a closed position. The operations of fitting a bag, conveying a filled bag away, introducing filling material into the pre-storage space (4) and controlling the flap can be effected independently of each other. <IMAGE>

SPECIFICATION
Bag-filling connection for filling upwardly open bags with dusty products
The invention relates two a bag-filling connection for filling upwardly open bags with dusty products.
A bag-filling connection for this purpose is disclosed in German patent specification No. 3 309 531 and comprises a suction means having at least one suction nozzle; two spreader flaps which are pivotable about horizontal axes; clamping jaws associated with the spreader flaps and pivotable about horizontal axes to fix the edge of the mouth opening of the bag to the spreader flaps; skirts which form the front ends ofthe suction nozzle, are made from flexible material and are fixed to the spreader flaps orto parts which are fixed with respect to the flaps; for side fold bags, a folding device associated with the skirts, and movable with itsfolding meansfromout- side the bag-filling connection in a direction towards the space within the bag-filling connection; and for flat bags a spreading device associated with the skirts and movable with its spreading means from the inside outwardly. Such a bag-filling connection is provided with a suction means which is essentially formed from two suction connections or nozzles which are connected to a vacuum pump.Accord- ingly,thewhole ofthespace inside the bag-filling connection is uninterruptedly subjected to a vacuum. That has the effect that, besides air, filling material is also sucked away, thereby giving rise to fluctuations in weight which make it necessary sub- sequently to add material to the contents ofthe bag, by virtue of a conveyor belt-type check weighing machine which is disposed downstream of the filling connection.The filling material which is sucked away may not negligible since a relatively large amount of air has to be sucked away.
A disadvantage with all previously proposed bagfilled connections is that the filling material flows in a condition offreefall from a net-weightweighing machine which is disposed above a back-filling connection, into the bag. Accordingly,thefilling material also entrains a comparatively large amount of air as it falls into the bag and that air must be removed again from the bag. The amount of airto be removed is further increased by virtue of the fact that air flows into the bag when the spreader flaps are open. A particularly important consideration is that the upper edge of the bag should be free of particles of dust, so as to permit reliable formation of a closure seam welding or adhesive. Therefore, the removal of dust is a matter of particular significance.Accordingly, in previously proposed bag-filling con nections,the assembly has included internal shakers or vacuum probes which can be introduced into a bag which has been filled orwhich is being filled.
However, that requires a relatively high level of structural expenditure. Furthermore, also known are external shakers which are set in operation during the filling process.
Another disadvantage that also occurs in the known bag-filling connections is that a subsequently continuing flow of material results in furtherfluctuations in weightand also gives rise to undesirable deposits of dust at the edge ofthe bag.
According to the invention there is provided a bagfilling connection forfilling upwardly open baga with dusty products comprising a suction means having at least one suction nozzle; two spreader flaps which are pivotable about horizontal axes to clamp the edge ofthe mouth opening of a bag to befilled to the spreader flaps; skirts which form the front ends of the suction nozzle, are made from flexible material and are fixed to the spreader flaps orto parts which are fixed with respect to the flaps; for side fold bags, a folding device associated with the skirts and movable with its folding means from outside the bagfilling connection; and,forflatbags,aspreadingde- vice associated with the skirts and movable with its spreading means from the inside outwardly; in which a suction opening of the or each suction nozzle, which opening is disposed in the space within the bag-filling connection, is closable by a closureflap; one or more chambers which are delimited in a downward direction by the lower edge ofthe spreaderflaps, in the space inside the bag-filling connection, can be subjected to reduced pressure by the suction means; the space within the bag-filling connection includes a pre-storage space which, when the spreaderflaps are closed, is closed downwardly and laterally in a dust-tight manner; and the closure flap is opened after a bag has been fitted to the bag-filled connection and is closed during the operation offilling a bag.
In such a bag-filling connection, in each operating phase, the suction means and the chambers which are subjected to a reduced pressure thereby can be separated from the filling material, the bag which is fitted to the bag-filling connection can have the air removed priorto the filling operation, the filling op eration can be carried outwith a small heightoffall of material, which is ofthe optimum value, and a continuing subsequentflowoffilling material is prevented.
Thus, as the suction opening of each suction connection or nozzle can be closed by the closure flap, theairflowcan be interrupted. Asthe closureflap can be of such a configuration that it opens the suction opening afterthe bag has been applied to the filling connection, whi le the spreader jaws are stil I closed, it can be assumed that at least a considerable partofthe air present in the empty bag is sucked away. Accordingly, in the subsequentfilling operation, particularly when dealing with filling materials in powderform,theamountofdustproducedissub- stantially smaller thereby also substantially reducing the danger of filling material being sucked away. As the closure flap can be closed prior to the operation of introducing the filling material into the bag, the suction effect will not be effective during the filling operation so that no filling material escapes at that time. At the end of the filling operation, the closure flap is normally opened in order to suck away at least the dust which clingstotheupperedge ofthe bag so that the bag can reliably be closed by a welded or adhesive seam.
The heightoffall ofthefilling material can be con siderably reduced as the filling material flows into the bag from the pre-storage space which lies directly above the upper edge of the bag. The reduced distance to be covered by the filling material means thatthe amount of airwhich is swirled up is also additionally reduced. Furthermore, the air can be removed from the filling material in the pre-storage space before the next bag is clamped to the bagfilling connection.The pre-storage space can contri bute substantially to increasing output since, as soon as the filling operation is terminated, the next batch of material can already be dumped from the netweight weighing machine which is disposed above the filling hopper, more specifically before the pre- viouslyfilled bag is removed from the filling station.
Further advantages ofthe bag-filling connection of the invention can arise from the chambers which are to be subjected to the effect of a reduced pressure as in thatwaythefilling material is not adverselyaffected by the vacuum. Thus the bag-filling connection can comprise a filling shaft and one or more suction passages which are separated from each other. By virtue of the combination of the features, it can be assumed that the generation of dust, with all the consequences thereof, is substantially reduced.
In accordance with a preferred embodiment having two suction connections or nozzles which are disposed in the region of the front ends of the bag-filling connection, it is provided thatthetwo chambers which can be acted upon by a reduced pressure are delimited at their ends by the flexible skirts. That construction affords the advantage that, besides the spreaderflaps being dust-tightly closed off at each end, the arrangementforms a suction passage which is disposed between the rubber skirts and the prestorage space.
In a simple construction, the pre-storage space may be delimited bytwo shaped or moulded members which are mounted pivotably about horizontal axes, are of a U-shaped cross-section, reduce or taper in a downward direction and mutually overlap with tnangularend walls. The pre-storage space can be opened orclosed ion a particularly simple manner if the shaped members are fixedly connected to the spreaderflaps. That arrangement prevents a continuing subsequent flow of material if the gaps which occur in the closure position are closed off by shaped sealing strips.
In another also preferred construction, the prestorage space may be delimited by a rubber or plastics tube which is fixed to thefilling connection and which is dust-tightly closed in the lower edge region, in the closure position of the spreaderflaps, by pressure bars which are fixed thereto. With that construction,there is no need for movable components within the pre-storage space.
The invention is diagrammatically illustrated by way of example in the accompanying drawings, in which :

Figure 9 is a view of part of a bag-filling connection having a pre-storage space which is in the form of a tube; and
Figure 10 is a sectional view of part ofthe arrangemenu shown in Figure 9.
Filling apparatus as shown in Figure 1 comprises a bag-fil I ing nozzle or connection 1 and a filling hopper 2which is arranged above it. A bag 3 which has already been filled is suspended on the bag-filling connection 1. A pre-storage space 4 which will be described in greater detail hereinafter is provided within the bag-filling connection 1. As shown the pre-storage space 4 has already been filled with filling material, before the previously filled bag 3 has been conveyed away from the bag-filling connection 1. The bag-filling connection 1 is equipped in known mannerwithclampingjaws5which are arranged in pairs, and spreaderflaps 6 which are also arranged in pairs.The clamping jaws 5 and the spreaderflaps 6 can be pivoted into two limit positions, Figure 1 showing only the two positions of the clamping jaws 5. The upper edge of the bag lies between the clamping jaws and the spreaderflaps.
As Figure 1 clearly shows, the filling material falls over an extremely short height as the pre-storage space 4 is disposed directly above the upper edge of the bag. Internal shakers or vacuum probes (not shown) can be disposed in the pre-storage space 4.
Figure 1 further shows that arranged above the prestorage space 4 at each side thereof is a suction nozzle or connection 7 which will be described in greater detail hereinafter, for removing dust from the interiorthereof.The arrows indicatethewayin which air is sucked out ofthe internal space, in the position shown in Figure 1.
In Figure 2, the filling operation has just ended.
The spreaderflaps 6 and the clamping jaws 5 are still opened, and likewise the pre-storage space 4. As comparison between Figures 1 and 2 shows, im- mediately after closure of the flaps 6 and clamping jaws 5, the pre-storage space 4 is already filled with filling material again.
Figures 3 and 4 which correspond to the view shown in Figure 1 showthatthefilling apparatus of
Figures 1 to 4 is designed for flat bags. Forthatpur- pose, disposed at each of the sides of the bag-filling connection lisa respective spreading means9comprising spreading fingers 8. Figure 3 illustrates three different positions for each spreading finger 8. The inner position ofthe spreading fingers corresponds to the open position and the middle position corresponds to the closure position of the spreader flaps 6. The outer position of the spreading fingers corresponds to the position with the edge ofthe bag spread out flat, after the bag has been fitted to the bag-filling connection, with the spreader flaps 6 and the clamping jaws 5 closed.
Figure 4 clearly shows that the pre-storage space4 does not extend asfarasthe end edges of the sprea derflaps6,therebyforming suction passages 10 which are in communication with the suction nozzles 7. The outer end edges ofthe suction chambers 10 are enclosed by rubber skirts 11 which are fixed, in a mannerwhich will be described hereinafter, with theirfree vertical edges to the ends of the spreader flaps 6. The suction passages extend into the region ofthe upper edge ofthe mouth opening of the bag.
The filling apparatus shown in Figures Sand 6 is designed for side fold bags. In accordance therewith, arranged at each of the two sides thereof is a respect ive folding device 12 which is essentially formed from a folding finger 13which is pivotable abouta horizontal axis and which bears against the bag or against the rubber skirt 11 on the outside thereof, and a slider 14 which is disposed beneath the free end of the folding finger 13. FigureS illustrates the two limit positions of the folding finger 13. in that connection, the outer position corresponds to the open position ofthe bag-filling connection 1 while the inner position corresponds to the closure position ofthe bag-filling connection 1 and inwardlydisposed side folds.Those two positions correspond to the inner and middle positions ofthe slider 14. The outer position of the slider 14 corresponds to the position after the bag has been fitted to the bagfilling connection 1, with the spreader flaps 6 and clamping jaws 5 still in a closed condition. It will also be seen from Figure 5that a flap 16 is provided in the suction connection 7 and is pivotable about a horizontal axis 15 between an open and a closed position. The open position is shown at 16' in FigureS.
The configuration of the pre-storage space4 is illustrated in Figures 7 and 8. As shown therein, the lower part comprises two shaped or moulded members 17 and 18which areofa U-shaped configuration in cross-section and which are screwed to the spreaderflaps 6. The side walls extend parallel to the respective spreader flap 6. The end walls on one side are disposed at a small spacing from each other. As shown in particular in Figure 8, the end walls ofthe member 17 embrace those ofthe member 18. Figure 7 showsthatthe end walls ofthe member 18are of a triangularconfiguration, in the mannerof a point.
That configuration provides that a hopper is also formed when the spreaderflaps 6 are in the closed condition. As can be seen in particularfrom Figures 1 and 8, a sealing strip 20 is fitted into the lower, horizontally extending edge of the member 17. Afurther shaped sealing strip 21 is fitted to the free end ofthe end walls of the member 17. The sealing strips 20 and 21 firmly close the gaps which are formed by the members 17 and 18 when the spreaderflaps 6 are in the closed condition, thereby effectively preventing a subsequent continuing flow offilling material therethrough.
In the construction shown in Figure 9, the pre storage space4 has aflexibletube 22 of rubberor plastics material while associated therewith at its lower end are pressure bars 23 which are fixed to the spreaderflaps 6. In the illustrated embodiment, the pressure bars 23 are provided with inclined surfaces at their longitudinal edges, thereby providing a sealing surface when the spreaderflaps are in a closed condition. The pressure bars 23 are denoted by reference numeral 23' in the closed position. Figure 10 shows in particular the way in which the rubber skirts 11 are fixed to spreaderflaps 6. As shown therein, folding plates 25 are secured to the end edges of the spreader flaps 6 by means of screw-on plates 24, and the respective edges ofthe rubber skirts 11 arefolded arund the plates 25.The plates 25 are designed for a respective width of bag and accordingly are changed overwhen converting the machine to a different bag format. Figure 10 also shows that the upper edge of the bag bears sealingly against the outside surfaces of the respective rubber skirt 11. The bag illustrated is a flat bag. Itwill be seen thatthespreadingfinger8shown in Figures3 and4 bears against the associated rubber skirt 11, on the inside thereof. The position ofthe rubber skirt 11 and the folding plates 25 is shown in dash-dotted lines with the spreaderflaps 6 in the closed condition, and indicated by reference numerals 11' and 25' respectively. Instead of the flexible tube 22 illustrated, it is also possible to use the construction incorporat ingthe U-shaped members 17.In a manner not shown in the drawings, the arrangement may also include pairs ofgripperswhich are mounted laterally of the spreading finger 8, for flat bags of different widths, the opening effectively preventing a subse quentcontinuingflowoffilling materialthere- through.
In the construction shown in Figure 9, the prestorage space 4 has a flexible tube 22 of rubber or plastics material while associated therewith at its lower end are pressure bars 23 which are fixed to the spreader flaps 6. In the illustrated embodiment, the pressure bars 23 are provided with inclined surfaces at their longitudinal edges, thereby providing a sealing surface when the spreader flaps are in a closed condition. The pressure bars 23 are denoted by reference numeral 23' in the closed position. Figure 10 shows in particular the way in wh ich the rubber skirts 11 are fixed to the spreaderflaps 6. As shown therein, folding plates 25 are secured to the end edges ofthe spreader flaps 6 by means of screw-on plates 24, and the respective edges of the rubber skirts 11 are folded around the plates 25.The plates 25 are designed for a respective width of bag and accordingly are changed overwhen converting the machine to a different bag format. Figure 10 also shows that the upper edge of the bag bears sealingly against the outside surfaces ofthe respective rubber skirt 11. The bag illustrated is a flat bag. It will be seen thatthespreading finger8 shown in Figures 3 and4 bears against the associated rubber skirt 11, on the inside thereof. The position ofthe rubber skirt 11 and thefolding plates 25 is shown in dash-dotted lines with the spreader flaps 6 in the closed condition, and indicated by reference numerals 11' and 25' respectively. Instead of the flexibletube 22 illustrated, it is also possible to use the construction incorporating the U-shaped members 17. In a manner not shown in the drawings, the arrangement may also include pairs ofgrippers which are mounted laterally of the spreading finger 8, for flat bags of different widths, the opening cross-section being suitably adapted to the operating range of the spreaders by means ofthe pairs of grippers. The grippers define the opening cross-section when dealing with bags of greater widths.
After an empty bag 3 has been fitted to the bag filling connection 1,eachflapl6ofthebag-filling connection 7 is moved into the open position priorto opening ofthe spreader flaps 6. In that way the bag which is suspended from the filling connection is at least partially evacuated, in other words, it remains in a flat condition. The pre-storage space 4 will have already been filled by the weighing machine (not shown), in which respect the bag-filling connection 1 may also be in the form of a weighing container of a weighing machine. After closure ofthe flaps 16, the spreaderjaws 6 are opened and the filling material contained in the pre-storage space 4flows into the bag with, it will be noted, minimum height of fall.
Afterthe bag has been filled,the spreader flaps 6 and the pre-storage space 4 are closed. The flaps 16 are returned to the open position whereby substantially the upper edge of the bag is vacuum cleaned. Even before the bag is releasedfromthe bag-filling connection 1 by opening of the clamping jaws 5, the prestorage space 4will have been filled again. The next following bag can then befitted and filled in the above-described manner.
