Description
DK 97 00475 U3DK 97 00475 U3
Opfindelsen angår en fyldemaskine til pakning af forskellige produkter i ventilsække og forsynet med en støvsugeledning og flere fylderør, hvorpå de ventilsække, som skal fyldes, kan påsættes, samt tilordnet en tilbageføringsanordning.The invention relates to a filling machine for packing various products in valve bags and provided with a vacuum suction line and several filling pipes, on which the valve bags to be filled can be mounted, and assigned a return device.
Sådanne fyldemaskiner findes i to udførelsesformer. Den ene er de såkaldte række-5 pakkemaskiner, hvor de enkelte fyldemaskiner er anbragt på en række ved siden af hinanden.Such filling machines are available in two embodiments. One is the so-called row-5 wrapping machines, where the individual filling machines are arranged on a row next to each other.
Den anden udførelsesform er opbygget som roterende fyldemaskine. Dennes rotor drives enten med konstant omdrejningstal eller skridtvist.The second embodiment is designed as a rotary filling machine. Its rotor is operated either at constant speed or stepwise.
Fyldemaskiner arbejder ifølge to forskellige systemer. Ved det ene system er der nederst i en pakkesilo anbragt en fyldeturbine, som leder produktet ind i fylderøret og dermed 10 til den påsatte ventilsæk. Ved det andet system er der tale om en såkaldt luftpakker, hvor fyldegodset transporteres ved hjælp af trykluft. Produktet indføres i maskinen fra en forsilo.Filling machines work according to two different systems. In one system, a filling turbine is placed at the bottom of a packing silo which directs the product into the filling tube and thus 10 to the valve bag fitted. In the second system, this is a so-called air packer in which the loading goods are transported by means of compressed air. The product is introduced into the machine from a front silo.
Ofte benyttes en fyldemaskine til flere forskellige produkter. Det er da nødvendigt ved produktskift at udtømme restmængden ved en renseoperation.Often a filling machine is used for several different products. When changing the product, it is necessary to exhaust the residual amount in a cleaning operation.
Det er herfor kendt at forsyne pakkemaskinerne med en separat tømmeanordning ved .It is known for this to provide the packing machines with a separate emptying device by.
15 hjælp af hvilken restmængden af fyldegodset kan ledes til en tilbageføringsanordning. En sådan tilbageføringsanordning er nødvendig for at opfange og tilbageføre fyldegods fra fejl-behæftede eller sammenklappede sække. Da den separate anordning imidlertid ikke arbejder kontinuerligt, kan der forekomme skorpedannelse, således at udtømningen ofte er utilstrækkelig. Og det er umuligt eller vanskeligt at kontrollere tømningen. Restudtømningen opfylder 20 derfor ikke de krav brugeren stiller. Desuden forbliver der i fyldekanalen en restmængde af produktet som iblandes det efterfølgende produkt.15 by means of which the residual amount of the filling goods can be directed to a return device. Such a reversing device is necessary to intercept and retrieve filling goods from defective or collapsed bags. However, since the separate device does not operate continuously, crustal formation may occur, so that the discharge is often insufficient. And it is impossible or difficult to control the emptying. The residual discharge therefore does not meet the requirements of the user. In addition, there remains in the filling channel a residual amount of the product which is incorporated into the subsequent product.
I praksis kan restudtømningen alternativt ske ved at det pågældende fylderør påsættes en ventilsæk, hvis bund er fjernet eller åben. På basis af den udstrømmende mængde af fyldgods skønner man, at renseoperationen er gennemført på tilfredsstillende måde. Ved begge de 25 nævnte rensemetoder er støvudviklingen en stor ulempe som skyldes tilbageføringen i et åbent system. Støvet er en belastning for driftspersonalet og medfører en tilsmudsning af fylde-maskinen og dens omgivelser.In practice, the residual discharge can alternatively be effected by attaching the respective filling pipe to a valve bag whose bottom is removed or open. On the basis of the outflow amount of fill goods, it is estimated that the cleaning operation has been carried out satisfactorily. In both of the 25 cleaning methods mentioned, dust development is a major disadvantage due to the return in an open system. The dust is a burden on the operating staff and causes a dirtying of the filling machine and its surroundings.
Formålet med opfindelsen er at anvise en fyldemaskine af den omhandlede art, hvor den ved produktskifte nødvendige restudtømning kan ske automatisk, hvorved det skal sikres, 30 at der i praksis ikke findes restmængder af fyldegods i fyldeaggregatet. Og renseoperationen skal forløbe uden støvdannelse.The object of the invention is to provide a filling machine of the kind in question, where the residual depletion required at the time of product change can be done automatically, thereby ensuring that in practice there are no residual quantities of filling material in the filling unit. And the cleaning operation must proceed without dusting.
Dette opnås ifølge opfindelsen ved, at der til resttømning af fyldemaskinen ved et produktskifte ved maskinens periferiområde findes mindst en med tilbageføringsanordningen forbundet tømmeledning, som på strømningsgunstig måde kan forbindes med fylderørene et 35 efter et.This is achieved according to the invention in that, for residual emptying of the filling machine by a product change at the peripheral area of the machine, there is at least one drain line connected to the return device, which can be connected to the filling pipes one by one in a flow-favorable manner.
Denne restudtømning er især anvendelig i forbindelse med roterende fyldemaskiner. Tømmeledningen placeres et egnet, ikke af andet udstyr optaget sted. Når fyldemaskinen drives skridtvis, påsættes tømmeledningen fylderørene et efter et. Efter tømning af et fylderør 2 DK 97 00475 U3 drejes fyldemaskinen et skridt. Drives maskinen med konstant omdrejningstal, kan man anvende et yderligere positioneringsdrev til rengøring af de enkelte fyldeaggregater.This residual discharge is particularly useful in connection with rotary filling machines. The discharge line is placed in a suitable location not occupied by other equipment. When the filling machine is operated step by step, the emptying line is fitted one by one. After emptying a filling tube 2 DK 97 00475 U3, the filling machine is turned one step. If the machine is operated at a constant speed, an additional positioning drive can be used to clean the individual filling units.
Ved et rækkepakkeanlæg kan anvendes en teleskoplignende eller bevægelig tømmledning. I modsætning til, hvad der er kendt, sker restudtømningen nu via fyldekanalen eller fylderøret, således at restudtømningen kan betragtes som en normal fyldeoperation.A telescopic-like or movable discharge line can be used in a row packing system. Contrary to what is known, the residual discharge now takes place via the filling channel or filling tube, so that the residual discharge can be considered a normal filling operation.
Takket være den strømningsgunstige forbindelse til tilbageføringsanordningen kan man ved passende udformning opnå et i det væsentlige støvfrit system. Ved hjælp af en føler er det muligt at overvåge, om renseprocessen er startet, henholdsvis om fyldehovedet er tømt. Under restudtømningen er det hensigtsmæssigt, at den øverst i fyldemaskinen anbragte støvsuger sættes ud af drift for ikke at modvirke strømmen af fyldegods.Thanks to the flow-favorable connection to the return device, a substantially dust-free system can be obtained by suitable design. With the help of a sensor it is possible to monitor whether the cleaning process has started or whether the filling head has been emptied. During the residual discharge, it is desirable that the vacuum cleaner located at the top of the filling machine be put out of operation so as not to counteract the flow of filling goods.
Ved en roterende fyldemaskine kan tømmeledningen være fast, stationært placeret et egnet sted. Da det fylderør, som skal tømmes, altid befinder sig i en bestemt position, kan tømmeledningen være svingbar. Når den ikke bruges, befinder tømmeledningen sig så i en hvilestilling uden for fylderørenes arbejdsområde. Til svingning af tømmeledningen anvendes foretrukket et lineært drev, eksempelvis en stempel-cylinderenhed. Under restudtømningen medbringes også støv fra fyldeaggregatet. Takket være kontrolmuligheden sikres det, at den hidtil uundgåelige forurening af produkterne ikke mere forekommer.In the case of a rotary filling machine, the discharge line may be fixed, stationary at a suitable location. Since the filling pipe to be emptied is always in a certain position, the emptying pipe may be pivotal. When not in use, the discharge line is then in a resting position outside the work area of the filling tubes. A linear drive, for example a piston-cylinder unit, is preferably used for oscillating the discharge line. Dust from the filling unit is also carried during the residual discharge. Thanks to the control, it is ensured that so far the inevitable contamination of the products no longer occurs.
Det er hensigtsmæssigt, at tømmeledningen er forbundet med en i tilbageføringsanordningen indgående overgangstragt, som er anbragt over og forbundet med en tilbageføringssnekke. Overgangstragten kan betragtes som et mellemlager, hvori det udtømte fyldegods først opfanges. Det er herved fordelagtigt, at overgangstragten er forbundet med en sugeledning til bortsugning af støv. Denne udsugning understøtter virksomt renseprocessen, således at renhedsgraden i fyldeaggregatet øges yderligere. For at man kan afbryde renseprocessen såsnart der ikke mere ledes fyldegods fra fylderøret er det hensigtsmæssigt, at tømmeledningen er forsynet med en føler til overvågelse af tømmeprocessen. Denne føler monteres på en sådan måde i tømmeledningen, at den befinder sig nær fylderørets udgangsåbning, når tømmeledningen er forbundet med fylderøret.Conveniently, the discharge line is connected to a transition funnel included in the return device which is disposed over and connected to a return screw. The transitional funnel can be considered as an intermediate storage in which the depleted filling material is first intercepted. It is advantageous hereby that the transition funnel is connected to a suction line for dust extraction. This extraction effectively supports the purification process, so that the purity of the filling unit is further increased. In order to be able to interrupt the cleaning process as soon as filling goods are no longer led from the filling pipe, it is desirable that the emptying pipe is provided with a sensor for monitoring the emptying process. This sensor is mounted in such a manner in the discharge conduit that it is near the exit opening of the filling tube when the discharge conduit is connected to the filling tube.
Opfindelsen skal i det følgende forklares nærmere i forbindelse med tegningen, som skematisk viser en del af en roterende fyldemaskiner med tømmeledning og tilbageførings-anordning.The invention will now be explained in more detail in connection with the drawing, which schematically shows a portion of a rotary filling machine with discharge line and return device.
Den viste roterende fyldemaskines 10 rotor kan drives med konstant omdrejningstal eller skridtvis. Drejevinklen under hvert skridt afhænger af antallet af fylderør 11. Drives rotoren med konstant omdrejningstal, kan man benytte et hjælpedrev i form af et intervaldrev i forbindelse med renseprocessen. Til restudtømning af de enkelte fyldeaggregater i den roterende fyldemaskine 10 føres fylderørene 11 et efter et til en forudbestemt nøje fastlagt position, således at den om en vandret akse svingbare tømmeledning 12 kan påsættes det pågældende fylderør.The rotor of the shown rotary filling machine 10 can be operated at constant speed or stepwise. The angle of rotation during each step depends on the number of filling tubes 11. If the rotor is operated at a constant speed, an auxiliary drive can be used in the form of an interval drive in connection with the cleaning process. For residual discharge of the individual filling assemblies in the rotary filling machine 10, the filling tubes 11 are guided in a position which is precisely defined to a predetermined axis so that the emptying pipe 12, which can be swiveled about a horizontal axis, can be applied to the respective filling pipe.
3 DK 97 00475 U3 På tegningen er tømmeledningen i arbejdsstilling betegnet 12, medens den i en hvilestilling - under fyldning af ventilsække - er betegnet 12'. På ikke nærmere vist måde har tømmeledningen 12 ved sin mod fylderøret 11 vendte ende en tætningsmanchet. Tømmeledningens 12 modsatte, nederste ende er forbundet med en overgangstragt 13. Denne tragt 13 5 er forbundet med en tilbageføringssnekke 14, der er en del af tilbageføringsanordningen. Tømmeledningen 12 kan svinges mellem arbejds- og hvilestilling ved hjælp af et lineært drev 15, eksempelvis en stempel-cylinderenhed. Overgangstragten 13 er forbundet med en sugeledning 16 til bortsugning af støv.3 DK 97 00475 U3 In the drawing, the emptying line in the working position is designated 12, while in a resting position - while filling valve bags - it is designated 12 '. In no way shown, the discharge line 12 has a sealing sleeve at its end facing the filling tube 11. The opposite, lower end of the drain line 12 is connected to a transition funnel 13. This hopper 13 5 is connected to a return screw 14 which is part of the return device. The discharge line 12 can be pivoted between the working and resting positions by means of a linear drive 15, for example a piston-cylinder unit. The transition funnel 13 is connected to a suction line 16 for dust extraction.
Ved den viste udførelsesform er der under den roterende fyldemaskines 10 pakkesilo 10 17 drejeligt lejret en turbine 18. Fylderøret 11 befinder sig på højde med turbinen 18, som drives af en motor 19. Dette fyldesystem skal dog kun betragtes som et eksempel. Den roterende fyldemaskine 10 har endvidere et tilførselsrør 20 og en øvre støvsugende ledning 21. Øvrige for den roterende fyldemaskines 10 drift nødvendige aggregater, såsom en vejemekanisme og en sækholder, er af hensyn til overskueligheden ikke vist. Til tømning af de 15 enkelte fyldeaggregater bringes fylderørene 11 et efter et til den med tømmeledningen 12 passende stilling. Når tømmeledningen er påsat det pågældende fylderør, indledes så at sige en vægtuafhængig fyldeoperation der varer indtil føleren 23 i tømmeledningen erkender, at der ikke mere er fyldegods i det pågældende fyldeaggregat. Under rense- eller tømmeprocessen standses støvudsugningen gennem den øverste ledning 21, medens sugeledningen 16 fra 20 tragten tilsluttes en vakuumkilde. Herved understøttes renseprocessen. Ved hjælp af en i overgangstragten 13 anbragt føler 22 kontrolleres fyldhøjden, og renseprocessen afbrydes eventuelt kortvarigt på ikke nærmere vist måde.In the embodiment shown, a turbine 18 is rotatably mounted below the packing silo 10 17 of the rotary filling machine 10. The filling tube 11 is at the same level as the turbine 18 driven by a motor 19. However, this filling system is only to be considered as an example. Furthermore, the rotary filling machine 10 has a supply pipe 20 and an upper vacuum suction line 21. Other assemblies necessary for the operation of the rotary filling machine 10, such as a weighing mechanism and a bag holder, are not shown for clarity. For emptying the 15 individual filling assemblies, the filling tubes 11 are brought one by one to the position corresponding to the emptying line 12. When the discharge line is attached to the relevant filling pipe, so to speak, a weight independent filling operation is initiated which lasts until the sensor 23 in the discharge line recognizes that there are no longer loading goods in the filling unit in question. During the cleaning or emptying process, the dust extraction is stopped through the upper conduit 21, while the suction conduit 16 from the funnel 20 is connected to a vacuum source. This supports the cleaning process. By means of a sensor 22 arranged in the transition funnel 13, the filling height is checked and the cleaning process is interrupted briefly in a manner not shown in detail.
Den beskrevne udtømningsproces er især anvendelig ved roterende fyldemaskiner, men kan også ved passende udformning af tømmeledningen 12 anvendes ved rækkepakke-25 maskiner. Det væsentlige er, at restmaterialet udtømmes gennem fylderørene.The discharging process described is particularly useful for rotary filling machines, but can also be used in row packing machines in the appropriate design of drain line 12. Essentially, the residual material is discharged through the filling tubes.
