Description

DK 161242 BDK 161242 B

Den foreliggende opfindelse angår et apparat til fyldning af ventilsække og af den i krav l's indledning angivne art.The present invention relates to an apparatus for filling valve bags and of the kind specified in the preamble of claim 1.

Et sådant apparat kendes eksempelvis fra DE-C-25 12 761 5 og benyttes til påfyldning af meget forskelligartet fyldgods. Ved omstilling fra en type gods til en anden er det især ved produkter i den kemiske industri nødvendigt at foretage en yderst grundig rengøring, da i paksiloen tilbagesiddende rester kan medføre reaktioner med senere på-10 fyldt gods.Such an apparatus is known, for example, from DE-C-25 12 761 5 and is used for filling very different fill goods. When switching from one type of cargo to another, it is especially necessary for products in the chemical industry to perform a very thorough cleaning, as residual residues in the pack silo can cause reactions with later refilled goods.

Hver af apparatets fyldestudse er del af en fyldeind-retning, som kendes i forskellige udførelser. De forskellige udførelser har relation til arten af fyldgods. Man kan derved gå ud fra, at en bestemt gruppe af fyldgods påfyldes 15 med samme fyIdeindretning. Blandt fyIdeindretninger skelnes mellem indretninger med lyftfyldning og indretninger med en fyldeturbine. Førstnævnte type er især egnet for tungtflyd-ende gods og for blandinger med bestanddele, der har forskellig kornstørrelse. Fyldning af sækkene sker ved disse 20 indretninger under anvendelse af trykluft. De med fyldeturbine arbejdende indretninger er især egnede for pulveriseret gods.Each of the filling filler nozzles is part of a filling device known in different embodiments. The different designs are related to the nature of the fill. It can thus be assumed that a certain group of filling goods is filled with the same filling device. Distribution devices distinguish between lifting devices and filling turbine devices. The former is particularly suitable for heavy-duty goods and for mixtures with components having different grain sizes. The bags are filled by these 20 devices using compressed air. The filling turbine-operated devices are particularly suitable for powdered goods.

De hidtil kendte fyldeapparater med en roterbar paksilo er kun egnede for hver en bestemt type fyldgods. Denne be-25 grænsede anvendelighed er særlig uheldig, da et fyldeappa-rat som bekendt kun udgør en del af et komplet anlæg.The prior art filling apparatus with a rotatable pack silo is only suitable for each particular type of filling material. This limited utility is particularly unfortunate, as a filling device, as you know, is only part of a complete system.

Formålet med opfindelsen er at anvise et fyldeapparat af den indledningsvist angivne art, hvor paksiloen uden risiko for sammenblandinger kan forsynes med forskelligt 30 fyldgods, hvorhos der inde i apparatet sikres en adskilt fremføring af det forskellige gods frem til fyldestudsene.The object of the invention is to provide a filling apparatus of the type mentioned initially, where the pack silo can be supplied with different filling loads without risk of mixing, whereby a separate feed of the various goods is secured up to the filling nozzles.

Dette opnås ifølge opfindelsen ved den i krav 1 anviste udformning.This is achieved according to the invention in the embodiment of claim 1.

Det er herved muligt ved en tilsvarende udformning af 35 det samlede anlæg at påfylde flere typer fyldgods samtidigt, da hvert ringkammer med tilordnet studs eller tilordnede studse og kanaler danner et i sig selv lukket system, således at gods ikke kan sammenblandes. Heller ikke sammen- 2It is thus possible, in a corresponding design of the total system, to load several types of filler at the same time, as each ring chamber with assigned studs or assigned bounces and ducts forms an intrinsically closed system so that goods cannot be confused. Neither together- 2

blanding på vej til de respektive ringkamre kan finde sted, da hvert ringkammer er tilordnet sin egen indløbsstuds. Der er også ved den anviste udformning mulighed for at påfylde kun et materiale. Det herfor bestemte ringkammer forsynes 5 da med fyldgods, medens de med de tomme ringkamre forbundne fyldestudse sættes ud af drift.mixing on the way to the respective ring chambers can take place, as each ring chamber is assigned its own inlet plug. It is also possible in the design according to the design to load only one material. The annular chamber provided for this is then provided with stuffing material, while the filling spigots connected with the empty annular chambers are put out of operation.

Særligt fordelagtigt ved den anviste udformning er det, at paksiloen svarende til antallet af ringkamre kan bestyk-kes med forskellige udførelsesformer for fyIdeindretninger.Particularly advantageous in the design disclosed is that the packing silo corresponding to the number of annular chambers can be embroidered with different embodiments of fixtures.

10 I normal udførelse ligger antallet af til paksiloen hørende fyldestudse mellem seks og tolv. Heraf fremgår, i hvilke varianter et fyldeapparat ifølge opfindelsen kan udføres.10 In the normal design, the number of filling plugs of the pack silo is between six and twelve. From this it appears in which variants a filling apparatus according to the invention can be made.

En særlig fordelagtig udførelsesform er anvist i krav 2. Ved denne bundudformning opnås en fordeler af det ring-15 kammeret tilførte gods. Formen af de til et ringkammer tilordnede kanaler er ens, hvorhos dog de til de enkelte ringkamre tilordnede kanaler er forskellige, da det er . nødvendigt at føre de til det inderste ringkammer hørende kanaler udad for at bringe den i forbindelse med fyldeind-20 retningerne. Såfremt paksiloen er forsynet med forskellige fyldeindretninger, er kanalernes udløb udformet i overensstemmelse hermed. De konstruktive omkostninger ved paksiloen er særligt små ved den i krav 5 anviste udformning.A particularly advantageous embodiment is disclosed in claim 2. In this bottom configuration, a distributor of the ring-supplied chamber material is obtained. The shape of the channels assigned to a ring chamber is similar, although the channels assigned to the individual ring chambers are different as it is. it is necessary to extend the channels belonging to the inner ring chamber outwardly to bring it into contact with the filling devices. If the packing silo is provided with different filling devices, the outlets of the ducts are designed accordingly. The constructive cost of the pack silo is particularly small in the design according to claim 5.

Opfindelsen skal i det følgende forklares nærmere i 25 forbindelse med tegningen, hvor fig. 1 viser et lodret snit gennem et fyldeapparat ifølge opfindelsen, fig. 2 et snit gennem en del af apparatets paksilo i større målestoksforhold, og 20 fig. 3 et snit langs linien III-III i fig. 2.The invention will now be explained in more detail in connection with the drawing, in which 1 shows a vertical section through a filling apparatus according to the invention; FIG. 2 is a section through a portion of the device's silo in larger scale, and FIG. 3 is a section along line III-III of FIG. 2nd

Det i fig. 1 viste fyldeapparat består i det væsentlige af en paksilo 1 tilordnet flere, hver med en fyldestuds 2 forsynede fyldeindretninger 3. Ved den viste udførelsesform består paksiloen 1, som det tydeligere frem-25 går af fig. 2, af en overdel la og en til denne flangeforbundet underdel 16. Som det især fremgår af fig. 3, har overdelen la et inderste og et yderste ringkammer 4 henholdsvis 5. Ringkamrene 4,5 adskilles af en koncentrisk 3The FIG. 1 is essentially comprised of a packing silo 1 assigned to several, each having a filling device 3 provided with a filling nozzle 2. In the embodiment shown, the packing silo 1 consists, as can be seen more clearly in FIG. 2, of an upper part 1a and one of the flange-connected lower part 16. As can be seen in particular in FIG. 3, the tops 1a have an inner and an outer ring chamber 4 and 5. The ring chambers 4,5 are separated by a concentric 3

med omdrejningsakslen forløbende mellemvæg 6. Ringkamrene 4,5 strækker sig ved den viste udførelsesform eksempelvis over omkring en fjerdedel af paksiloens 1 samlede højde. Apparatet har en central aksel 7, som er sammenkoblet 5 med en ikke nærmere omtalt drivmekanisme 8. Paksiloens 1 øverste begrænsning udgøres af et faststående låg 9, som i det foreliggende tilfælde har to åbninger, gennem hvilke to ringkamrene tilordnede indløbsstudse 10 og 11 er ført. Indløbsstudsen 10 udmunder i det inderste ringkammer 4, 10 medens studsen 11 udmunder i det yderste ringkammer 5. Via disse indløbsstudse tilføres siloens kamre gods fra en eller flere ikke viste forrådssiloer.The intermediate wall extending with the rotational shaft 6. The annular chambers 4,5 extend, for example, to about one quarter of the total height of the paxilos 1. The apparatus has a central shaft 7, which is coupled 5 with an unspecified drive mechanism 8. The upper limitation of the shaft 1 is constituted by a fixed lid 9, which in the present case has two openings through which two annular chambers 10 and 11 are assigned to the annular chambers. . The inlet nozzle 10 opens in the inner ring chamber 4, 10 while the nozzle 11 opens in the outer annular chamber 5. Via these inlet nozzles the goods of the silo are supplied from one or more storage silos not shown.

Især af fig. 1 fremgår det, at der under hvert ringkammer 4,5 findes til fyldestudsene 2 førende kanaler 4a 15 henholdsvis 5a. De til det inderste ringkammer 4 hørende kanaler 4a er trukket udad, medens det yderste ringkammers 5 kanaler 5a er ført ind mod midten. Som følge heraf går kanalerne 4a forbi kanalerne 5a.In particular, FIG. 1, it appears that under each annulus 4,5 there are conduits 4a 15 and 5a for the filling nozzles 2 and 5a respectively. The channels 4a of the inner ring chamber 4a are extended outwardly, while the channels 5a of the outer ring chamber 5 are directed towards the center. As a result, channels 4a pass channels 5a.

Af fig. 3 fremgår, at fyldeapparatet i den forelig-20 gende udførelse ikke blot har to ringkamre 4 og 5, men at paksiloen derudover er udformet med seks fyldestudse.In FIG. 3 shows that in the present embodiment, the filling apparatus not only has two ring chambers 4 and 5, but that the packing silo is additionally formed with six filling nozzles.

Hvert ringkammer er derfor tilordnet tre kanaler 4a henholdsvis 5a. Ringkamrenes nederste begrænsning udføres af i samme afstand i kammeret indsatte, til tagform bukkede 25 plader. I fig. 3 er de i det inderste ringkammer 4 indsatte plader betegnet 4b, medens pladerne i det yderste kammer 5 er betegnet 5b.Each ring chamber is therefore assigned to three channels 4a and 5a, respectively. The lower limitation of the ring chambers is carried out by the same distance inserted into the chamber, for roof form, bent 25 plates. In FIG. 3, the plates inserted in the inner ring chamber 4 are designated 4b, while the plates in the outer chamber 5 are designated 5b.

Under det yderste ringkammers 5 tagformede plader 5b forløber de fra det inderste ringkammer 4 udgående kanaler 30 4a. Som følge af dette liggerde fra det yderste ringkammer 5 udgående kanaler 5a mellem kanalerne 4a. Den øverste del af hver kanal 4a,5a er tragtformet, hvorhos den øverste kant er forsat nedad i forhold til de tagformede plader 4b og 5b. Den nederste del af kanalerne 4a,5a kan være 35 udformet i ét,eller den tragtformede del kan være indsat i det inderste henholdsvis det yderste ringkammer 4,5.Under the roof-shaped plates 5b of the outer ring chamber 5, the channels 30 4a projecting from the inner ring chamber 4 extend. As a result, channels 5a extending from the outer ring chamber 5 lie between channels 4a. The upper portion of each duct 4a, 5a is funnel-shaped, the upper edge of which is downwardly relative to the roof-shaped plates 4b and 5b. The lower portion of the channels 4a, 5a may be formed in one, or the funnel-shaped portion may be inserted into the inner and outer annular chambers 4,5, respectively.

Kanterne af de tagformede plader 4b og 5b og kanterne på den tragtformede del må overlappe på en sådan måde, at 4The edges of the roof-shaped plates 4b and 5b and the edges of the funnel-shaped part must overlap in such a way that 4

hvert ringkaimner forneden er begrænset som af en bund, der har åbninger, hvorigennem gods kan strømme ud i kanalerne.each ring bottom is limited as by a bottom having apertures through which goods can flow into the channels.

De til det inderste ringkammer 4 hørende åbninger 12 er ved den viste udførelsesform trapezformede, medens den 5 ydre begrænsning dog er bueformet. De til det yderste ringkammer 5 hørende åbninger 13 er her cirkulære, men mange varianter kan tænkes, blot åbningerne sikrer, at der fra ringkamrene 4,5 kun strømmer fyldgods til de tilhørende kanaler.The apertures 12 of the inner ring chamber 4 are trapezoidal in the illustrated embodiment, while the outer limitation is arcuate. The openings 13 of the outer ring chamber 5 are here circular, but many variants are conceivable, just as the openings ensure that from the ring chambers 4,5, only fillings flow to the associated channels.

10 Som fig. 1 viser, er fyldeapparatet forsynet med to forskelligt udformede fyldeindretninger 3. Fyldeindretningen hørende til det yderste ringkammer 5 arbejder efter luft-fyIdesystemet, medens den til det inderste ringkammer 4 hørende fyldeindretning arbejder med en fyldeturbine 14.10 As FIG. 1 shows that the filling apparatus is provided with two differently shaped filling devices 3. The filling device belonging to the outer ring chamber 5 operates according to the air-filling system, while the filling device belonging to the inner ring chamber 4 operates with a filling turbine 14.

15 Sådanne fyldeindretninger er almindelig kendte og skal ikke omtales nærmere i denne sammenhæng. Benyttes flere end to ringkamre, kan tilsvarende flere forskellige fyldeindretninger benyttes. Fyldeprocessen styres af en til hver fyIdestuds 2 hørende, elektronisk styret automatisk vægt 20 15, som heller ikke kræver nærmere omtale. Ved den forelig gende udførelsesform er den ligeledes til hver fyldestuds 2 hørende sækholder 16 udformet sådan, at den også tjener som vægtskål.Such filling devices are well known in the art and are not to be discussed further in this connection. If more than two ring chambers are used, several different filling devices can be used correspondingly. The filling process is controlled by an electronically controlled automatic weight 20 15, which is associated with each of the two feet, which also does not require further discussion. In the present embodiment, the bag holder 16 of each filler nozzle 16 is also designed so that it also serves as a weight bowl.

Over den med trykluft arbejdende, det yderste ringkammer 25 5 tilordnede fyldeindretning 3 ligger et cylinderformet trykkammer 17, hvori fyldegodset mellemlagres, inden det fyldes i ventilsækkene. Øverst i trykkammeret 17 findes to over hinanden anbragte lukkekegler 18, som ved hjælp af ikke viste stempel-cylinderaggregater kan bevæges i lod-30 ret retning. I stedet kan benyttes kun en ventilkegle eller et andet lukkeorgan. Antal og udformning af lukkeorganer afhænger af fyldgodsets kornstørrelse.Above the filling device 3, which operates with compressed air, is a cylindrical pressure chamber 17 in which the filling material is interposed before it is loaded into the valve bags. At the top of the pressure chamber 17 there are two superimposed closing cones 18 which can be moved in the vertical direction by means of piston-cylinder assemblies not shown. Instead, only one valve cone or other closure means may be used. The number and design of the closure means depends on the grain size of the filler.

Ved den anden, med luft arbejdende fyldeindretning kan godsstrømmen afbrydes ved hjælp af en af et stempel-35 cylinderaggregat 20 drivbar skyder 21.In the second, air-operated filling device, the goods flow can be interrupted by a slider 21 driven by a piston-cylinder assembly 20.

Apparatet er ophængt i to over 1 åget 9 vandret forløbende bærejern 19.The appliance is suspended in two carrier iron 19 extending horizontally over 1 year 9.
