Den foreliggende opfindelse angår et apparat til stykvis aftagelse af stablede ventilsække og til påsætning af ventilsække på en ventilsæksfyldemaskines påfyldningsstuds eller -studse og af den i krav 1’s indledning angivne art.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for the piecewise removal of stacked valve bags and for the application of valve bags to the filling socket or plug of a valve bag filling machine and of the nature specified in the preamble of claim 1.
5 Ved et fra DE 28 25 918 A1 kendt apparat står de sække som skal aftages stykvis på en sidekant. Separeringen sker ved hjælp af en svingbar sugeliste, som kan ansættes mod den med ventil forsynede bund og dernæst fra lodret kan svinges til vandret stilling. Sækken hænger derefter frit ned fra sugelisten. Efterfølgende bevæges under sugelisten anbragte oprettelister mod hinanden, således at den med ventilen forsynede bund kan støtte mod disse. Sugelisten 10 bevæges dernæst i retning mod en båndtransportør, således at denne overtager sækken og fører den til fyldemaskinen. Over båndtransportøren findes et i retning mod fyldemaskinen tværsnitsmæssigt formindskende formrør til at åbne ventilen.5 In an appliance known from DE 28 25 918 A1, the bags are to be removed piecemeal on a side edge. The separation is done by means of a pivotable suction strip, which can be applied to the valve-mounted bottom and then can be pivoted from the vertical to the horizontal position. The bag then hangs freely from the suction box. Subsequently, the guide strips placed underneath the suction strip are moved towards each other so that the bottom provided with the valve can support them. The suction strip 10 is then moved in the direction of a belt conveyor so that it takes over the bag and carries it to the filling machine. Above the belt conveyor there is a cross-sectional reducing pipe in the direction towards the filling machine to open the valve.
Det er ved denne udformning en ulempe, at ventilsækkene, når de påsættes fylderørene, ikke er 15 eksakt positioneret, hvorfor det ofte sker, at sækkene ikke kan påsættes korrekt. Desuden er det konstruktive opbud og pladsbehovet forholdsvis stort.In this embodiment, it is a disadvantage that the valve bags, when fitted to the filling tubes, are not exactly positioned, which is why it often happens that the bags cannot be fitted correctly. In addition, the constructive supply and space requirements are relatively large.
Fra DE 27 19 459 A1 kendes et apparat til at separere ventilsække og påsætte dem på en fyldemaskines fylderør, og hvor sækkene aftages fra stablen ved hjælp af en sugemekanisme 20 og lægges på et vandret transportbånd. Overparten af dette transportbånd er tilordnet en vendemekanisme, hvormed sækken overdrages til en lodret transportør, der fører sækken så meget længere, at den med ventil forsynede bund når ind i området for påsætningsklør. Under disse påsætningsklør er der også anbragt oprettelister. Over disse lister findes en i lodret retning bevægelig sugemekanisme til at foråbne ventilen. Også dette apparat er yderst kompli-25 ceret, således at der allerede derfor kan forekomme fejlpåsætninger. Desuden er vendingen af ventilsækkene meget ugunstig.DE 27 19 459 A1 discloses an apparatus for separating valve bags and attaching them to the filling tube of a filling machine, and where the bags are removed from the stack by means of a suction mechanism 20 and placed on a horizontal conveyor belt. The upper part of this conveyor belt is provided with a reversing mechanism by which the bag is transferred to a vertical conveyor which carries the bag so much longer that the valved bottom reaches into the area of application claws. Under these claws are also put-up lists. Above these moldings is a vertical suction mechanism for opening the valve. This apparatus is also extremely complicated, so that errors can already occur. Furthermore, the turning of the valve bags is very unfavorable.
Udgående fra den teknik, som kendes fra DE 28 25 918 A1. er formålet med opfindelsen at anvise et apparat af den omhandlede art, som er mere kompakt og giver enklere 30 bevægelsesforiøb, hvorved apparatet er billigt at fremstille og arbejder sikkert og nøjagtigt.Starting from the technique known from DE 28 25 918 A1. The object of the invention is to provide an apparatus of the present invention which is more compact and provides simpler 30 steps of movement, whereby the apparatus is inexpensive to manufacture and operates safely and accurately.
Dette opnås ved den i krav 1's kendetegnende del anviste udformning.This is achieved by the design according to the characterizing part of claim 1.
De to drivmekanismer er konstruktivt meget enkle. Desuden kan kfemlisternes bevægelse 35 fastlægges nøje. Ved hjælp af drivmekanismen med lang bevægelse, der foretrukket er et styret tandremsdrev, føres sugelisten til den øverste stilling, i hvilken den i forhold til oprettelisternes svingakser står forsat opad. Den dernæst nødvendige nedadgående bevægelse til fladlægning af ventilbunden og påfølgende returbevægelse opad til åbning af ventilen sker ved 2 DK 173644 B1 hjælp af drivmekanismen med den korte bevægelse, fortrinsvis en puenmatisk cylinder. Benyttes den pneumatiske cylinder også til at sænke sugelisten så meget, at en ventilsæk kan overtages, er det hensigtsmæssigt, at cylinderens arbejdstryk ændres. Under den nedadgående bevægelse kan arbejdstrykket da eksempelvis ligge mellem 1 og 2 bar. medens det ved 5 den opadgående bevægelse kan være omkring 6 bar.The two drive mechanisms are constructively very simple. In addition, the movement of the chemists can be determined precisely. By means of the long-motion drive mechanism, which is preferably a guided toothed belt drive, the suction strip is moved to the upper position in which it is facing upwards relative to the swivel axes of the uprights. The downward movement then required to flatten the valve bottom and subsequent return movement upward to open the valve is effected by the short-motion drive mechanism, preferably a pneumatic cylinder. If the pneumatic cylinder is also used to lower the suction strip to the extent that a valve bag can be taken over, it is advisable to change the working pressure of the cylinder. During the downward movement, for example, the working pressure may be between 1 and 2 bar. while at 5 the upward movement may be about 6 bar.
Drivmekanismen med den korte bevægelse kan ved hjælp af en passende styring udgøres af drivmekanismen med den lange bevægelse, når styringen er således udformet, at sugelistens nedadgående bevægelse til antrykning mod ventilbunden og dens opadgående bevægelse til 10 åbning af ventilbunden sker via sidstnævnte drivmekanisme. Sugelisten transporterer ventilsækken til en sådan stilling, at de til driftsstillingen bevægede oprettelister står under ventilsækkens bund. Når sugelisten dernæst frigiver ventilsækken, falder denne ned og hviler på oprettelisterne. Sugelisten bevæges så nedad, hvorved ventilbunden fladtrykkes. Bunden står da vinkelret på sækkens vægge, således at der fremkommer et T-formet område. Derved er der 15 skabt optimale forudsætninger for transporten videre til fylderørene.The short-motion drive mechanism can be constituted by the long-motion drive mechanism by an appropriate control when the control is designed such that the downward movement of the suction strip for abutment to the valve bottom and its upward movement to open the valve base takes place via the latter driving mechanism. The suction strip transports the valve bag to such a position that the upright strips moved to the operating position are below the bottom of the valve bag. When the suction strip then releases the valve bag, it falls down and rests on the uprights. The suction strip is then moved downwards, thereby flattening the valve bottom. The bottom is then perpendicular to the wall of the bag so that a T-shaped area appears. As a result, 15 optimum conditions have been created for transport to the filling pipes.
Alternativt er oprettelisteme tilordnet nok et åbningselement for ventilen. Dette åbningselement kan eksempelvis være en dorn eller en løftearm. Da det skal sikres, at ventilen under transporten til fyldestudsen forbliver åben, er apparatet fordelagtigt udformet på en sådan måde, at 20 ventilbunden ved ventilen gribes af vinkelformede formplader, der er svingbare om vandrette akser. Oprettelisterne kan på konstruktiv simpel vis bringes i driftsstilling og grundstilling, når de er svingbare om indbyrdes parallelle og med indbyrdes afstand forløbende vandrette akser.Alternatively, the opening strips are assigned another opening element for the valve. This opening element may, for example, be a mandrel or a lifting arm. To ensure that the valve remains open during transport to the filler neck, the apparatus is advantageously designed in such a way that the valve bottom at the valve is gripped by angular shaped plates which are pivotable about horizontal axes. The creation moldings can be constructed in a simple and constructive manner in operating position and basic position when they are pivotable about mutually parallel and spaced horizontal axes.
For at sækkens position efter fiadtrykning af ventilen fikseres ved hjælp af en ikke vakuumsat 25 sugeiiste er det hensigtsmæssigt, at hver opretteliste er anbragt på en svingarm og består af en fast med svingarmen forbundet bakke og en i forhold til bakken, i den pågældende svingarms længderetning bevægelig klemliste.In order that the bag position after compression of the valve is fixed by means of a non-vacuum 25 suction strip, it is desirable that each bucket list is arranged on a swing arm and consists of a fixed tray connected to the swing arm and a longitudinal direction relative to the tray. movable clamping strip.
Når sækkens ventilbund er fladlagt, fastklemmes den af klemlisterne. Derved er det muligt ved 30 bevægelse opad af sugelisten at åbne ventilen, således at åbningselementet lettere kan indføres.When the bag valve bottom is flattened, it is clamped by the clamping strips. In this way it is possible to move the valve upwards by the movement of the suction strip, so that the opening element can be inserted more easily.
Da det kan forekomme, at den aftagne ventilsæk under bunden slår folder, er det til undgåelse af driftsforstyrrelser hensigtsmæssigt, at oprettelisterne i forhold til driftsstillingen kan bevæges i 35 vandrette, indbyrdes modsatte retninger. Herved er det muligt først at vælge afstanden mellem de to oprettelister så stor, at listerne ikke berører sækken. Derefter kan listerne bevæges mod hinanden, således at afstanden kun er så stor. at sækken kan hænge fast. Aktivering af klemlisterne sker så først efter at ventilbunden er fladlagt ved hjælp af stemplet. I stedet for sugeli- 3 sten kan til fladlægninri af ventilbunden anvendes et styret stempel. Ellers udfylder sugelisten en dobbelt funktion.Since it may occur that the removed valve bag underneath the bottom beats folds, it is desirable that, in order to avoid disruptions in operation, the starting lists can be moved in horizontal, mutually opposite directions to the operating position. This makes it possible to first select the distance between the two creation lists so large that the lists do not touch the bag. Then the moldings can be moved towards each other so that the distance is only so great. that the bag can hang. The terminal strips are then activated only after the valve bottom is flattened by means of the piston. Instead of the suction mold 3, a controlled piston can be used for flat laying of the valve bottom. Otherwise, the suction list fills a dual function.

15 Det på tegningen viste apparat er anbragt i et ikke nærmere omtalt stel 10. I ringe afstand over stellets grundflade er anbragt et bevægeligt magasin 11 til optagelse af en stabel af ventilsække. I den ene side af stellet findes en fra magasinområdet opad sig strækkende tandrems-drivmekanisme 12, der kan betragtes som et langvejsdrev. I denne drivmekanisme 12, der drives af en reversibel drivmotor 13, er fastgjort en sugeliste 14. I fig. 1 er med fuld streg vist 20 denne sugelistes laveste stilling. Sugelistens 14 øverste endestilling er antydet med stiplet streg 14'. Sugelisten 14 bevæges udelukkende i lodret retning. Som fig. 1 viser, er sugelisten 14 anbragt på stempeistangen i en stempelcylinderenhed 16. Denne enhed 16 er selv anbragt på en holder 17, som ved hjælp af tandremsdrivmekanismen 12 kan bevæges i lodret retning. Sugelisten 14 kan således bibringes en relativ bevægelse i forhold til drivmekanismen 12.15 The apparatus shown in the drawing is arranged in an unspecified frame 10. At a short distance above the base surface of the frame is a movable magazine 11 for accommodating a stack of valve bags. On one side of the frame there is an upwardly extending toothed belt drive mechanism 12 extending from the magazine area, which can be regarded as a long-distance drive. In this drive mechanism 12, driven by a reversible drive motor 13, is attached a suction strip 14. In FIG. 1 is shown in full line 20 in this suction list's lowest position. The top end position of the suction strip 14 is indicated by dashed line 14 '. The suction strip 14 is moved exclusively in the vertical direction. As FIG. 1 shows the suction strip 14 is mounted on the piston rod in a piston cylinder unit 16. This unit 16 is itself mounted on a holder 17 which can be moved in the vertical direction by means of the toothed belt drive mechanism 12. Thus, the suction strip 14 can be imparted in relative motion to the drive mechanism 12.
25 Sugelisten 14 er forsynet med sugekopper, som på ikke nærmere vist måde kan evakueres.The suction strip 14 is provided with suction cups which can not be evacuated in a detailed manner.
Fig. 1 viser tydeligt, hvorledes en ved hjælp af sugelisten 14 fra stablen aftaget ventilsæk overføres til en lodret stilling, når sugelisten 14 befinder sig i sin øverste endestilling 14'. I fig. 1 er ventilsækken 18 vist med åben ventil. I denne ventil er indført en om en lodret akse svingbar åbningsdorn 19.FIG. 1 clearly shows how a valve bag removed by the suction strip 14 is transferred to a vertical position when the suction strip 14 is in its upper end position 14 '. In FIG. 1, valve bag 18 is shown with open valve. Into this valve is inserted an opening mandrel 19 which is pivotable about a vertical axis.

Apparatet har i den øverste del to cm vandrette akser 20 svingbare oprettelister 21 og 22. De vandrette akser 20 er indbyrdes parallelle og anbragt i indbyrdes afstand. Oprettelisterne 21,22 er anbragt på svingarme 23,24. Svingbevægelse af disse arme 23,24 og dermed af oprettelisterne 21,22 fremkaldes af ikke nærmere omtalte drivorganer 25,26. Oprettelisterne 21,22 er 35 også tilordnet to om vandrette akser 27,28 svingbare, vinkelformede formplader 29,30. Formpladerne er skruet fast på arme, som ved hjælp af to stempelcylinderenheder kan bevæges mod og bort fra hinanden. Formpladerne strækker sig over en del af en ventilsæks 18 bredde som især vist i fig. 1. I sammenført tilstand griber formpladerne 29,30 om ventilområdet på sækken 4 DK 173644 B1 18. Dette er i fig. 4 vist med stiplet streg. Ligeledes med stiplet streg er vist oprettelisternes 21 og 22 driftsstilling. Fig. 4 viser tydeligt, hvorledes sækkens 18 ventilbund hviler i fladlagt tilstand på oversiden af oprettelisterne 21,22. Af hensyn til tydeligheden er ventilåbningen vist med fuld streg. Denne ventilåbning omgribes af formpladerne 29,30.In the upper part the apparatus has two cm axes 20 pivotable uprights 21 and 22. The horizontal axes 20 are mutually parallel and spaced apart. The creation lists 21,22 are arranged on swing arms 23,24. Swing movement of these arms 23,24 and thus of the uprights 21,22 is induced by unspecified drive means 25,26. The uprights 21,22 are also assigned to two horizontal axes 27,28 pivotable angular shaped sheets 29.30. The mold plates are screwed onto arms which can be moved towards and away from each other by means of two piston cylinder units. The mold plates extend over a portion of the width of a valve bag 18 as shown in particular in FIG. 1. In assembled condition, the mold plates 29,30 engage the valve area of the bag 4 DK 173644 B1 18. This is shown in FIG. 4 shown in dash. The dashed lines 21 and 22 are also shown in dashed line. FIG. 4 clearly shows how the valve bottom of the bag 18 rests in a flattened state on the upper side of the uprights 21,22. For the sake of clarity, the valve opening is shown in full line. This valve opening is surrounded by the mold plates 29.30.

Fig. 4 viser udformningen af de to oprettelister 21,22 Ved den viste udførelsesform består hver liste af en med svingarmen 23 henholdsvis 24 fast forbundet, af et vinkelprofil fremstillet bakke 33 henholdsvis 34 og en i hver svingarms 23,24 længderetning bevægelig klemliste 35 henholdsvis 36, som er fremstillet af et vinkelprofil. Hver klemliste 35,36 kan bevæges ved hjælp af 10 en klemcylinder 37 henholdsvis 38. På ikke nærmere angivet måde kan bakkerne 33,34 bevæges sammen med klemlisterne 35 henholdsvis 36. Bevægelse af oprettelisterne 21,22 kan være lineær eller cirkelformet. Dette kan eksempelvis ske ved installering af drivorganer for bakkerne 33,34 og styring af disses bevægelse ved hjælp af kulissestyring. En anden mulighed består i at udforme svingarmene 23,24 teleskopisk. Øverst i apparatet og over de vandrette 15 akser 27,28 findes en ikke nærmere omtalt vandret transportør 39, med hvilken formpladerne 29,30 bevæges. Ved hjælp af denne transportør 39 kan ventilsækken 18 påsættes en ikke vist fyldemaskines fyldestuds.FIG. 4 shows the design of the two uprights 21,22 In the embodiment shown, each list consists of a fixed link 33 with a swivel arm 23 and 24 respectively, an angular profile made of 33 and 34 and a longitudinal movable clamping strip 35 and 36 respectively of each swivel arm 23, 24. which is made of an angular profile. Each clamping strip 35,36 can be moved by means of a clamping cylinder 37 or 38, respectively. In unspecified manner, the trays 33,34 can be moved together with the clamping strips 35 and 36 respectively. Movement of the uprights 21,22 can be linear or circular. This can be done, for example, by installing drive means for trays 33,34 and controlling their movement by means of backing control. Another possibility is to design the swing arms 23,24 telescopically. At the top of the apparatus and above the horizontal axes 27,28 there is an unspecified horizontal conveyor 39 with which the molding plates 29.30 are moved. By means of this conveyor 39, the valve bag 18 can be applied to the filling nozzle of a filling machine not shown.
Den elektriske og pneumatiske styring af apparatet er ikke vist og vil heller ikke kræve nærmere 20 omtale. Til aftagelse af en ventilsæk fra magasinet 11 føres sugelisten 14 nedad ved hjælp af tandremsdrivmekanismen 12. Stempelcylinderenhedens 16 stempel er ført ud. Arbejdstrykket ligger eksempelvis mellem 1 og 2 bar. Når sugelisten 14 berører ventilbunden på den øverste ventilsæk i stablen, kan sækken medbringes på grund af undertryk i listens 14 sugekopper. Ved passende kobling af drivmotoren 13 bevæges sugelisten 14 opad med drivmekanismen 12.The electrical and pneumatic control of the apparatus is not shown and will not require further discussion. To remove a valve bag from the magazine 11, the suction strip 14 is brought downward by means of the toothed belt drive mechanism 12. The piston of the piston cylinder unit 16 is extended. For example, the working pressure is between 1 and 2 bar. When the suction strip 14 touches the valve bottom of the upper valve bag in the stack, the bag can be carried due to negative pressure in the suction cups of the strip 14. By appropriate coupling of the drive motor 13, the suction strip 14 is moved upwards with the drive mechanism 12.
25 Under denne bevægelse øges arbejdstrykket i stempelcyfinderenheden 16. Når sugelisten 14 når en forudbestemt stilling, frakobles drivmotoren 13. Senest da indføres stempelstangen i stempelcylinderenheden 16, således at sugelisten 14 befinder sig i den øverste endestilling 14' Drivorganerne 25,26 tilkobles derefter for at svinge oprettelisterne 21,22 til de i fig. 4 med stiplet streg viste stillinger. Oprettelisterne 21,22 afgrænser en spalte for ventilsækkens 18 vægge.25 During this movement, the working pressure in the piston cylinder unit 16 is increased. As the suction strip 14 reaches a predetermined position, the drive motor 13 is switched off. Most recently, the piston rod is introduced into the piston cylinder unit 16, so that the suction strip 14 is in the upper end position 14 '. The drive means 25,26 are then switched on. pivot the uprights 21,22 to the ones in FIG. 4 in dashed positions. The create strips 21,22 define a slot for the 18 wall of the valve bag.
30 Sækkens ventilbund ligger på listernes 21,22 vandrette oversider, når sugelisten 14 har frigivet sækken 18, således at den kan falde frit. Til dannelse af det T-formede øverste område udskydes enhedens 16 stempelstang, således at den tjener som formestempel for ventilbunden. Dernæst føres ved aktivering af cylindrene 37,38 de yderste klemlister 35,36 mod hinanden, således at ventilsækken fastklemmes. Derefter evakueres sugelistens 14 sugekopper igen, og 35 ved indføring af stempelstangen i stempelcylinderenheden 16 løftes sugelisten, Herved dannes den forudbestemte åbning i ventilen. Endelig kan åbningsdornen 19 indføres i ventilen, hvis dette er nødvendigt for at holde ventilsækken 18. Derrefter føres stempelstængerne i enhederne 31,32, så'edes at de vinkelformede formplader 29,30 griber om ventilbunden og DK 173644 B1 5 holder ventilen åben. Ved hjælp af den vandrette transportør 39 bevæges derefter formpladerne 29,30 og derved også ventilsækken 18 mod fyldemaskinens fyldestuds. Transporten af ventilsækken 18 fra oprettestationen til fylderøret skyldes alene denne vandrette transportør 39, der også omfatter formpladerne 29,30.30 The valve bottom of the bag lies on the horizontal upper sides of the strips 21, when the suction strip 14 has released the bag 18 so that it can fall freely. To form the T-shaped upper region, the piston rod of the unit 16 is pushed out to serve as a piston mold for the valve bottom. Next, by activating the cylinders 37,38, the outer clamping strips 35,36 are brought towards each other so that the valve bag is clamped. Then the suction cups 14 of the suction strip 14 are evacuated again and 35 upon insertion of the piston rod into the piston cylinder unit 16 the suction strip is raised, thereby forming the predetermined opening in the valve. Finally, the opening mandrel 19 can be inserted into the valve if this is necessary to hold the valve sack 18. Thereafter, the piston rods are inserted into the units 31,32 such that the angular shaped plates 29.30 engage the valve bottom and the valve keeps the valve open. Then, by means of the horizontal conveyor 39, the molding plates 29,30 and thereby also the valve bag 18 are moved towards the filling nozzle of the filling machine. The transport of the valve bag 18 from the erection station to the filling tube is solely due to this horizontal conveyor 39, which also includes the mold plates 29.30.

Fig. 4 og 5 viser, hvorledes der på de vinkelformede klemlister 35,36 er fastgjort flere klodser 40,41. Klodserne er anbragt på det af klemlisternes 35,36 ben, som i driftsstilling står vandret og i grundstiliing lodret. Grundstillingen er den stilling, som tillader transport af en ventilsæk fra stablen. Klodserne 40,41 er anbragt med indbyrdes mellemrum, som det fremgår af fig. 5.FIG. 4 and 5 show how several blocks 40,41 are attached to the angular clamping strips 35,36. The bricks are placed on that of the 35,36 legs of the clamping strips, which are in a horizontal position in a vertical position and in the basic position. The basic position is the position that allows transport of a valve bag from the stack. The blocks 40, 41 are spaced apart as shown in FIG. 5th
10 Formplademe 29,30 er ved deres frie endeområder modsvarende fortandede, hvorhos de fremstående dele af endeområderne kan gribe ind i de af klodserne 40,41 afgrænsede mellemrum. Derved er det muligt at lukke formpladerne 29.30 sammen for at overtage ventilsækken 18, medens oprettelisterne 21,22 stadig er i deres driftsstilling. Når det er nødvendigt, at svingarmene 23,24 henholdsvis oprettelisterne 21,22 skal foretage en vandret bevægelse, kan 15 også de svingakser dannende vandrette akser 20,21 bevæges i vandret retning, som det er antydet med dobbeltpile. Det omhandlede apparat er især tænkt anvendt i forbindelse med rækkepakkemaskiner med et eller to fylderør. Herved tænkes især på en prisgunstig udførelse, som bl.a. opnås, ved at transporten af ventilsækkene med åben ventil sker ved hjælp af en enkelt vandret transportør 39 med tilhørende formplader 29,30. Ved en pakkemaskine med 20 mere end et fylderør må denne vandrette transportør bevæges på tværs af transportretningen for ventilsækkene 18.The mold plates 29,30 are correspondingly toothed at their free end regions, whereby the protruding portions of the end regions can engage the spaces delimited by the blocks 40, 41. Thereby, it is possible to close the molding plates 29.30 together to take over the valve bag 18, while the uprights 21,22 are still in their operating position. When it is necessary for the swing arms 23,24 and the uprights 21,22 respectively to make a horizontal movement, the horizontal axes forming horizontal axes 20,21 can also be moved in the horizontal direction, as indicated by double arrows. The apparatus in question is intended, in particular, to be used in connection with row packing machines with one or two filling pipes. This is especially thought of as an affordable design, which among other things. is achieved by transporting the valve bags with open valve by means of a single horizontal conveyor 39 with associated mold plates 29.30. In a packing machine with 20 more than one filling tube, this horizontal conveyor must be moved transversely of the transport direction of the valve bags 18.
Fig. 4 viser tydeligt, at de frie kanter af formplademe 29,30 for transport af ventilsækken 18 klemmer fast under dennes bund.FIG. 4 clearly shows that the free edges of the mold plates 29, 30 for transporting the valve bag 18 are clamped under its bottom.

Fig.6-8 viser opretningen af en ventilsæk 18. I fig. 6 har den lodret bevægelige sugeliste 14 grebet sækkens ventilbund og løftet sækken fra stablen. Når sugelisten 14 befinder sig i sin øverste endestilling, svinges oprettelisterne 21,22 til den sammenlukkede driftsstilling. Derefter aflastes sugelisten, således at sækken 18 frit kan falde i spalten mellem oprettelisterne 21,22.Figs. 6 to 8 show the arrangement of a valve bag 18. In fig. 6, the vertically movable suction strip 14 has gripped the bag bottom and lifted the bag from the stack. When the suction strip 14 is in its upper end position, the stop strips 21,22 are pivoted to the closed operating position. Then the suction strip is unloaded so that the sack 18 can freely fall into the gap between the creation strips 21,22.
30 Spalten har en bredde på eksempelvis 3 mm. Bunden af ventilsækken 18 vil ramme oprettelisterne 21,22. Afhængigt af ventilsækkens 18 egenstivhed vil positionen af ventilbunden variere fra sæk til sæk. For at opnå ensartet positionering bringes sugelisten 14 ved aktivering af stempelcylinderenheden 16 til at bevæge sig nedad. På grund af stempelvirkningen fladlægges ventilbunden mod klodserne 40,41 på oprettelisterne 21,22. Som det tydeligt frem-35 går af fig 8, står ventilbunden da vinkelret på sækvæggene; det nære område af ventilbunden og væggen bliver T-formet. Når ventilsækken 18 er fastholdt ved hjælp af klemcylindrene 37,38, evakueres sugelisten 14 og løftes. Herved åbnes sækkens 18 ventil som vist i fig. 5, og sækken føres af den vandrette transportør med formpladerne 29,30 til fyldemaskinens fylderør.The gap has a width of, for example, 3 mm. The bottom of the valve bag 18 will hit the uprights 21,22. Depending on the stiffness of the valve bag 18, the position of the valve bottom will vary from bag to bag. In order to achieve uniform positioning, the suction strip 14 is caused by movement of the piston cylinder unit 16 to move downwards. Due to the piston effect, the valve bottom is flattened against the bricks 40,41 on the uprights 21,22. As can be clearly seen from Fig. 8, the valve bottom is then perpendicular to the sack walls; the close area of the valve bottom and the wall becomes T-shaped. When the valve bag 18 is secured by the clamping cylinders 37,38, the suction strip 14 is evacuated and lifted. This opens the valve of the bag 18 as shown in FIG. 5, and the bag is carried by the horizontal conveyor with the molding plates 29.30 to the filling tube of the filling machine.
