Den foreliggende opfindelse angår et apparat af den i indledningen til krav 1 angivne art.The present invention relates to an apparatus of the kind set forth in the preamble of claim 1.

Håndtering af massegods, eksempelvis piller, granulater eller pulvere i store sække med en eller flere væg-5 ge anvendes i stadigt stigende omfang, og derved er pro blematikken med håndtering af sådanne sække blevet større.Handling of bulk goods, for example pills, granules or powders in large bags with one or more walls, is being used increasingly and thus the problem of handling such bags has become greater.

Især i forbindelse med fyldning og tømning af sækkene bliver arbejdsmiljøproblemerne store. Dette er specielt fremtrædende ved håndtering af pulverformigt materiale med 10 lille kornstørrelse i flergangs- eller returæske, fordi risikoen for indånding af pulverpartikler er specielt store i sådanne sammenhæng. Foruden arbejdsmiljøproblemet har det vist sig at være forbundet med vanskeligheder at fylde sækkene helt op uden dannelse af folder..Particularly in connection with filling and emptying of the bags, the working environment problems become large. This is particularly prominent when handling powdered material with 10 small grain sizes in multi-use or return boxes, because the risk of inhalation of powder particles is particularly high in such contexts. In addition to the working environment problem, it has been found to be difficult to fill the bags completely without the formation of folds.

15 Formålet med den foreliggende opfindelse er at anvi se et apparat, som uden alvorlige arbejdsmiljøproblemer muliggør fuldstændig og hurtig fyldning af pakningerne, først og fremmest når det gælder store sække.The object of the present invention is to use an apparatus which, without serious working environment problems, enables complete and rapid filling of the packages, first and foremost in the case of large bags.

Dette opnås ifølge opfindelsen ved, at et apparat 20 af den ovennævnte art udformes som angivet i den kende tegnende del af krav 1.This is achieved according to the invention in that an apparatus 20 of the above-mentioned type is designed as defined in the known drawing part of claim 1.

Ved opfindelsen muliggøres en tæt fyldning af store sække af forskellige typer uden dannelse af folder og udslip af miljøfarlige partikler i luften omkring arbejds-25 pladen.The invention enables a tight filling of large bags of various types without the formation of folds and the release of environmentally hazardous particles into the air around the work plate.

Opfindelsen skal i det følgende forklares nærmere i forbindelse med tegningen, hvor fig. 1 viser et apparat ifølge den foreliggende opfindelse, skematisk og set fra siden, 30 fig. 2 samme under fyldning af en stor sæk, og fig. 3 samme set fra oven med visse dele udeladt for tydeligheds skyld.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail in connection with the drawing, in which 1 is a schematic and side view of an apparatus according to the present invention; FIG. 2 shows the same during filling of a large bag; and FIG. 3 same view from above with some parts omitted for clarity.

Det viste apparat består af et mundstykke 1 og en ydre tragt 2. Mundstykket 1 har en konisk mundingsdel 3, 35 som med mellemrum omgiver et mundstyksrør 4. Mundstyks røret 4 omfatter et reguleringsorgan i form af et spjæld 5 og kan over en flange 6 slutte til en udtømnings- eller 2 151094 fremføringsanordning, eksempelvis i form af en fødeskrue (ikke vist). Den koniske mundingsdel 3 er foroven forsynet med et tag 7, som slutter tæt om mundstyksrøret 4.The apparatus shown comprises a nozzle 1 and an outer funnel 2. The nozzle 1 has a tapered nozzle portion 3, 35 which periodically surrounds a nozzle tube 4. for a discharge or feeding device, for example in the form of a feed screw (not shown). The conical orifice portion 3 is provided at the top with a roof 7 which ends tightly around the nozzle tube 4.

I taget 7 findes et fluidumindløbsrør 8 og et fluidum-5 udløbsrør 9. Fluidet kan hensigtsmæssigt bestå af luft.In the roof 7 there is a fluid inlet pipe 8 and a fluid 5 outlet pipe 9. The fluid may conveniently consist of air.

Indløbsrøret 8 har et reguleringsspjæld 10, og udløbsrøret 9 har et reguleringsspjæld 11. Når fluidet består af luft, kan indløbsrøret 8 være forbundet til en sædvanlig ventilator eller et eksisterende ventilationssystem.The inlet pipe 8 has a regulating damper 10 and the outlet pipe 9 has a regulating damper 11. When the fluid consists of air, the inlet pipe 8 can be connected to a conventional fan or existing ventilation system.

10 På ydersiden af den koniske mundingsdel 3 kan der findes organer til forbedring af friktion og/eller tætning, eksempelvis et gummilignende materiale.10 On the outside of the tapered orifice 3 there may be found means for improving friction and / or sealing, for example a rubber-like material.

Den ydre tragt 2 har en konisk indgangsdel 12, i hvilken den koniske mundingsdel 3 passer. Også indgangs-15 delen 12 kan på indersiden være forsynet med organer til frakobling af friktion og/eller tætning, eksempelvis et gummilignende materiale. Den koniske indgangsdel 12 går over i en rørformet udgangsdel 13, og i overgangen mellem de to dele 12,13 er anbragt luftorganer 14. I disse luft-20 organer 14 er fastgjort liner 15 og 16, som kan oprulles på ruller 17 og 18, der er fastgjort på samme aksel 19.The outer funnel 2 has a tapered entrance portion 12 into which the tapered mouth portion 3 fits. Also, the input member 12 may be provided on the inside with means for disconnecting friction and / or sealing, for example a rubber-like material. The tapered entrance portion 12 passes into a tubular outlet portion 13, and in the transition between the two portions 12,13 are provided air means 14. Lines 15 and 16 which are retractable on rollers 17 and 18 are secured to these air members which is attached to the same shaft 19.

Akslen 19 er koblet til en drivmekanisme 20.The shaft 19 is coupled to a drive mechanism 20.

I fig. 2 vises nærmere, hvorledes en stor sæk 21 af engangstypen fyldes ved hjælp af anordningen ifølge den 25 foreliggende opfindelse. Sækken 21 har en inderdel og en yderdel, og inderdelen er trukket op i den ydre tragt 2, således at mundingsdelen 3 og mundstyksrøret 4 kan føres ind i inderdelen. De^nne vil med tætning blive presset mod mundingsdelen 3, ved at den ydre tragt 2 løftes ved hjælp 30 af linerne 15,16. Derefter indføres fluidum, fortrinsvis luft, i inderdelen gennem indløbsrøret 8 over spjældet 10, således at inderdelen af sækken 21 opblæses, og dets vægge glattes ud. Den indførte luft slippes ud gennem udløbsrøret 9 over dets spjæld 11. Efter opblæsningen 35 af inderdelen kan materialeindfødningen begyndes ved åb ning af reguleringsspjældet 5.In FIG. Figure 2 illustrates how a large disposable sack 21 is filled by the device of the present invention. The sack 21 has an inner portion and an outer portion, and the inner portion is pulled up into the outer hopper 2 so that the mouth portion 3 and the mouthpiece tube 4 can be inserted into the inner portion. They will be sealed against the mouth portion 3 with sealing by lifting the outer funnel 2 by means of the lines 15,16. Thereafter, fluid, preferably air, is introduced into the inner portion through the inlet tube 8 over the damper 10 so that the inner portion of the sack 21 is inflated and its walls smoothed out. The introduced air is discharged through the outlet pipe 9 over its damper 11. After the inflation 35 of the inner part, the material feeding can be started by opening the regulating damper 5.

Efter delvis fyldning af sækken 21 lukkes spjældet 5, og den ydre tragt 2 sænkes ved hjælp af linerne 15 og 151094 3 16, og man lader inderdelen af sækken 21 glide mellem tragten 2 og mundstykket 1, hvorpå proceduren gentages.After partially filling the sack 21, the damper 5 is closed and the outer hopper 2 is lowered by means of the lines 15 and 151094, and the inner part of the sack 21 is slid between the hopper 2 and the nozzle 1 and the procedure is repeated.

På denne måde undgås dannelse af folder. Sækken 21 kan under fyldningen være anbragt på en hævelig og sænkelig 5 platform eller holdes oppe ved hjælp af en gaffeltruck eller på anden måde.In this way, formation of folds is avoided. The bag 21 may, during filling, be placed on a raised and lowered platform or held up by a forklift truck or otherwise.

I stedet kan tragten 2 være fast, og mundstykket 1 hæveligt og sænkeligt ved hjælp af en i princippet tilsvarende mekanisme for tragten 2, som omtalt.Instead, the hopper 2 may be fixed and the nozzle 1 swellable and lowerable by a basically similar mechanism for the hopper 2, as discussed.

10 Hvis mundingsrøret 4 fyldes med materiale ved hjælp af en fødeskrue, skal denne stoppes, når spjældet 5 er åbent og omvendt.10 If the nozzle 4 is filled with material by means of a feed screw, it must be stopped when the damper 5 is open and vice versa.
