Abstract

In a filling machine for sealing packages, use is made of a counter jaw arrangement (10) for a heat-generating jaw (13). The counter jaw arrangement (10) includes a counter body (20) and a carrier arm (30) for supporting the counter body (20). The counter body (20) is suspended at suspension devices (11, 12) rotatably about its longitudinal axis (l) for alignment with the heat-generating jaw (13). In their turn, the suspension devices (11, 12) are moveably connected to the carrier arm (30) and adapted for movement in a plane which is parallel with the longitudinal axis (l) of the counter body.

Description

528 044 10 15 20 25 30 35 grovinställs först manuellt med mothållets försegllngsyta i någorlunda planparallellitet med värmebackens förseglingsyta, fixeras och sedan provkörs förpackningsmaskinen. 528 044 10 15 20 25 30 35 is roughly set manually with the sealing surface of the abutment in a fairly plane parallel to the sealing surface of the heating jaw, fixed and then the packaging machine is tested.

Om förseglingarna inte är täta efter den första provkörningen stoppas maskinen och förseglingsbackarna lossas, justeras och fixeras återigen manuellt, varvid denna procedur upprepas till dess förpackningarna är tillräckligt täta.If the seals are not tight after the first test run, the machine is stopped and the sealing jaws are loosened, adjusted and fixed manually again, repeating this procedure until the packages are sufficiently tight.

Problemen med dessa kända mothållsupphängnlngar är att det krävs en stor manuell arbetsinsats vid inställning och kalibrering av de mot varandra tryckande förseglingsytorna och att om planparallelliteten ändras under produktionsdrift av förpackningsmasklnen måste maskinen stoppas med tillhörande höga kostnader och eventuell hög kassationsgrad för förpackningar.The problems with these known abutment suspensions are that a large manual work effort is required when adjusting and calibrating the opposing sealing surfaces and that if the plane parallelism changes during production operation of the packaging machine, the machine must be stopped with associated high costs and possibly high packaging discard.

Speciellt vid arbete med tunna förpackningsmaterial blir ett litet absolut fel vid inställningen av backarna ett relativt stort fel. På motsvarande sätt kommer en _ varierande tjocklek i förpackningsmaterialet att ge större utslag och påverkan för tunna förpackningsmaterial jämfört med ett relativt sett tjockare material.Especially when working with thin packaging materials, a small absolute error in setting the jaws becomes a relatively large error. Correspondingly, a varying thickness in the packaging material will give greater impact and impact for thin packaging materials compared to a relatively thicker material.

Vidare är framför allt mothållet som upphängs på kulleden svårt att justera då justering i en rörelseaxel kan innebära att mothållet hamnar fel i en annan rörelseaxel.Furthermore, above all, the abutment that is suspended on the ball joint is difficult to adjust, as adjustment in one axis of motion can mean that the abutment ends up wrong in another axis of motion.

Vid användning av de kända mothållsupphängningarna för försegling av förpackningsmaterial som endast uppvisar skikt av plastmaterial, dvs. tunnare förpackningsmaterial, är kraven på förseglingsbackarnas inställning mycket högre än för material som innefattar fiberskikt, dvs. tjockare förpackningsmaterial. Skälen till detta är dels att förpackningsmaterial med fibrer ofta är tjockare, vilket betyder att ett nominellt litet fel relativt materialtjockleken blir av mindre betydelse, dels att fiberskikten kan komprimeras upp till ca 2/3 av sin tjocklek innan fiberskiktet blir stumt, vilket förlåter nominellt mindre fel.When using the known abutment suspensions for sealing packaging material which only has layers of plastic material, ie. thinner packaging material, the requirements for the setting of the sealing jaws are much higher than for materials that include fibrous layers, ie. thicker packaging material. The reasons for this are partly that packaging material with fibers is often thicker, which means that a nominal small defect relative to the material thickness becomes less important, and partly that the fibrous layers can be compressed up to about 2/3 of their thickness before the fibrous layer becomes dull, which leaves nominally less wrong.

Sammanfattning av Uppfinningen Ett syfte med den föreliggande uppfinningen är att anvisa en lösning på de ovan nämnda problemen genom åstadkommande av ett förbättrat och självjusterande mothâllsarrangemang till en värmegenererande back för försegling av förpackningar i en förpackningsmaskin.Summary of the Invention An object of the present invention is to provide a solution to the above-mentioned problems by providing an improved and self-adjusting resistance arrangement to a heat-generating jaw for sealing packages in a packaging machine.

Detta syfte uppnås genom uppfinningen medelst ett mothàllsarrangemang av det inledningsvis angivna slaget, vilket har de särdrag som framgår av patentkrav 1 med föredragna utförandeformer i de efterföljande patentkraven 2-7.This object is achieved by the invention by means of a restraining arrangement of the kind stated in the introduction, which has the features which appear from claim 1 with preferred embodiments in the following claims 2-7.

Mothållsarrangemanget enligt uppfinningen till en värmegenererande back för försegling av förpackningar i en förpackningsmaskin innefattar ett mothäil och en bärarm för uppstödning av mothållet. Mothållet är upphängt vid upphängningsanordningar vridbart kring sin längdaxel för inriktning med den värmegenererande backen. Upp- hängningsanordningarna är i sin tur rörligt anslutna till bärarmen och anpassade för rörelse i ett plan som är parallellt med mothållets längdaxel och huvudsakligen vinkelrätt .JFP 1548 SE - APPL - as amended after first office actiormdoc 528 044 10 15 20 25 30 35 mot förpackningarnas längdaxel. Mothållet kan därmed ställa/vrida in sig, i två av varandra oberoende axlar, efter den värmegenererande backen om den är snedställd, dvs har vridit sig runt en axel som är parallell med mothållets längdaxel och/eller en axel som är vinkelrät mot mothållets längdaxel men parallell med förpackningarnas längd- /riktningsaxel, så att förseglingsytcr pà mothållet och värmegenereringsbacken därmed blir planparallella med varandra och förpackningen vid försegling av densamma. Detta förenklar kalibrering samt montering av mothållet och minskar därtill hörande manuell arbetsinsats. Den löpande anpassningen eller automatiserade injusteringen av mothållet korrigerar även för eventuellt förekommande tjockleksvariationer i förpackningsmaterialet samt förbättrar repeterbarheten i varje försegling och förbättrar även själva förseglingen jämfört med kända mothåll.The abutment arrangement according to the invention for a heat-generating jaw for sealing packages in a packaging machine comprises an abutment heel and a support arm for supporting the abutment. The abutment is suspended by suspension devices rotatable about its longitudinal axis for alignment with the heat-generating jaw. The suspension devices are in turn movably connected to the support arm and adapted for movement in a plane which is parallel to the longitudinal axis of the abutment and substantially perpendicular .JFP 1548 SE - APPL - longitudinal axis. The abutment can thus adjust / rotate, in two mutually independent axes, along the heat-generating slope if it is inclined, ie has rotated about an axis which is parallel to the longitudinal axis of the abutment and / or an axis which is perpendicular to the longitudinal axis of the abutment but parallel to the longitudinal / directional axis of the packages, so that the sealing surfaces on the abutment and the heat generation jaw thereby become plane-parallel with each other and the package when sealing the same. This simplifies calibration and mounting of the bracket and reduces the associated manual work effort. The continuous adjustment or automated adjustment of the abutment also corrects for any thickness variations in the packaging material and improves the repeatability of each seal and also improves the seal itself compared to known abutments.

I en alternativ utförandeform är mothållet _upphängt vid bärarmen via sina ändar medelst en tapp ivridbart ingrepp med tillhörande hål. l denna utförandeform vrider mothållet in sig efter värmegenereringsbackens inriktning vid försegling av förpackningen och förenklar kalibrering samt montering av mothållet, minskar därtill hörande manuell arbetsinsats, förbättrar repeterbarheten i varje försegling samt förbättrar själva förseglingen jämfört med kända mothåll.In an alternative embodiment, the abutment is suspended from the support arm via its ends by means of a pin rotatably engaging with associated holes. In this embodiment, the abutment turns in the direction of the heat generation jaw when sealing the package and simplifies calibration and assembly of the abutment, reduces the associated manual work effort, improves the repeatability of each seal and improves the seal itself compared to known abutments.

Mothâllsarrangemanget i en annan föredragen utförandeform är utformad med mothàllets ändar i kontakt med bärarmen medelst friktionsytor. Mothållet i denna utförandeform är självtnställande/-justerande genom att det vrider in sig efter eventuell snedställning av värmegenereringsbacken vid försegling av förpackningen och sedan behåller denna inställning då friktionen mellan kontaktytorna kvarhàller mothållet i den senast inställda positionen när mothållet och värmegenereringsbacken förs från varandra efter utförd försegling. Därmed förenklas kalibrering och montering av mothållet samt minskar därtill hörande manuell arbetsinsats och förenklas samt förbättras repeterbarheten i varje försegling och även själva förseglingen jämfört med kända mothåll.The abutment arrangement in another preferred embodiment is formed with the abutment ends in contact with the support arm by means of friction surfaces. The abutment in this embodiment is self-adjusting / adjusting in that it rotates after possible tilting of the heat generating jaw when sealing the package and then retains this setting as the friction between the contact surfaces retains the abutment in the last set position when the abutment and heat generating jaw after sealing . This simplifies calibration and assembly of the abutment and reduces the associated manual work effort and simplifies and improves the repeatability of each seal and also the seal itself compared to known abutments.

Mothållsarrangemanget i ännu en utförandeform är anordnad med upphängnings- anordningarna rörligt anslutna till bärarmen medelst fjädrande anordningar. Denna utförandeform av mothàllsarrangemanget ger den fördelen att mothållet och dess upphängningsanordningar ställer in sig efter eventuell snedställning/-vridning av värme- genereringsbacken runt en med förpackningarnas längdaxel huvudsakligen parallell axel och förenklar kalibrering och montering av mothållet samt minskar därtill hörande manuell arbetsinsats ytterligare. Detta förenklar samt förbättrar repeterbarheten i varje försegling och även själva förseglingen ytterligare jämfört med kända mothåll. l ytterligare en utförandeform av mothållsarrangemanget är friktionsytorna lös- tagbara friktionsbeläggl-inlägg. Denna utförandeform gör mothàllsarrangemanget själv- justerande genom att mothållet vrider in sig efter värmegenereringsbacken vid försegling ..fl'P 1546 SE - APPL - as amendod after first office actiondoc 528 044 10 15 20 25 30 35 av förpackningen och sedan behåller sin senast inställda position när mothället och värmegenereringsbacken förs från varandra efter förseglingen. Därmed förenklas kalibrering och montering av mothàllet, minskas därtill hörande manuell arbetsinsats, förenklas och förbättras repeterbarheten i varje försegling och själva förseglingen jämfört med kända mothàll.The restraining arrangement in yet another embodiment is arranged with the suspension devices movably connected to the support arm by means of resilient devices. This embodiment of the restraining arrangement provides the advantage that the restraint and its suspension devices adjust after any inclination / rotation of the heat generating jaw around an axis substantially parallel to the longitudinal axis of the packages and simplifies calibration and mounting of the abutment and further reduces associated manual work. This further simplifies and improves the repeatability of each seal and also the seal itself compared to known abutments. In a further embodiment of the abutment arrangement, the friction surfaces are detachable friction lining inserts. This embodiment makes the resistance arrangement self-adjusting in that the resistance turns inwards after the heat generation jaw when sealing ..fl'P 1546 SE - APPL - as amended after first office actiondoc 528 044 10 15 20 25 30 35 of the package and then retains its last set position when the counter and the heat generation jaw are moved apart after sealing. This simplifies calibration and assembly of the abutment, reduces the associated manual work effort, simplifies and improves the repeatability of each seal and the seal itself compared to known abutments.

Mothàllsarrangemanget i ännu en annan utförandeform är utformat så att varje ände av mothållet är i vridbart ingrepp med åtminstone en utskjutande tapp vid resp upphängningsanordnings främre mot värmegenereringsbacken vettande del. I denna utförandeform vrider mothållet in sig efter värmegenereringsbackens inriktning vid försegling av förpackningen och förenklar kalibrering samt montering av mothållet och minskar därtill hörande manuell arbetsinsats. Detta förbättrar även förseglinge- repeterbarheten och själva förseglingen jämfört med kända mothàll.The abutment arrangement in yet another embodiment is designed so that each end of the abutment is in rotatable engagement with at least one projecting pin at the front of the respective suspension device facing the heat generation jaw. In this embodiment, the anvil rotates in the direction of the heat generation jaw when sealing the package and simplifies calibration and assembly of the anvil and reduces the associated manual work effort. This also improves the seal repeatability and the seal itself compared to known resistors.

Mothàllet kan vidare vara i gängingrepp med åtminstone en separat pinne som sträcker sig igenom ett genom resp upphängningsanordnings bakre del gående häl, vars innerdiameter är större än pinnens ytterdiameter. Härigenom kan mothàllets rörelser begränsas.The abutment can furthermore be in threaded engagement with at least one separate pin which extends through a heel passing through the rear part of the respective suspension device, the inner diameter of which is larger than the outer diameter of the pin. In this way, the movements of the resistance can be limited.

Mothållet 20 har två ändar, en ände 20a till vänster rörligt ansluten mot en upphängningsanordning 11 och en ände 20b till höger rörligt ansluten mot en annan upphängningsanordning 12. Upphängningsanordningarna 11, 12 är rörligt anslutna till en bärarm 30 och uppstöder mothållet 20 mot bärarmen samt används också på känt sätt som hakar för ingrepp med motsvarande kända hakar vid ultraljudshornet 13 när förpackningarna förseglas.Figures 2-7 show the abutment arrangement 10 according to the invention and associated components. The abutment arrangement 10 comprises the substantially elongate abutment. ends, one end 20a on the left movably connected to a suspension device 11 and one end 20b on the right movably connected to another suspension device 12. The suspension devices 11, 12 are movably connected to a support arm 30 and support the abutment 20 against the support arm and are also used in a known manner as hooks for engagement with corresponding known hooks at the ultrasonic horn 13 when the packages are sealed.

Det nya mothållsarrangemanget 10 enligt uppfinningen är utformad med mothållet 20 upphängt vridbart kring sin längdaxel l vid vardera änden 20a, 20b medelst tappar 40 i vridbart ingrepp med tillhörande hål för inriktning med ultraljudshornet 13 (längdaxeln I visas i fig 3 där pilar visar dess rörelseriktning). En tapp 40 skjuter ut från resp upphängningsanordnings 11, 12 främre mot ultraljudshornet 13 vettande del (visas tydligt i fig. 3,5 och 7). Två separata, löstagbara pinnar eller bultar 50 av vilka var och en är i gängingrepp med ett bottenhål i vardera mothällsänden 20a, 20b sträcker sig huvudsakligen parallellt med mothållets längdaxel I igenom ett helt genom resp upp- hängningsanordnings 11, 12 bakre del gående hål, vars innerdiameter är större än bultens 50 ytterdiameter (visas tydligt i fig. 3, 5 och 6).The new abutment arrangement 10 according to the invention is formed with the abutment 20 suspended rotatably about its longitudinal axis 1 at each end 20a, 20b by means of pins 40 in rotatable engagement with associated holes for alignment with the ultrasonic horn 13 (longitudinal axis I is shown in Fig. 3 where arrows show its direction) . A pin 40 projects from the part of the respective suspension device 11, 12 facing the ultrasonic horn 13 (clearly shown in Figs. 3,5 and 7). Two separate, detachable pins or bolts 50, each of which is threaded with a bottom hole in each abutment end 20a, 20b, extend substantially parallel to the longitudinal axis I of the abutment through a hole passing completely through the rear part of the suspension device 11, 12, inner diameter is larger than the outer diameter of the bolt 50 (clearly shown in Figs. 3, 5 and 6).

Bultarna 50 (se fig. 3, 5 och 6) har som funktion att begränsa mothållets 20 vridrörelse kring Iängdaxeln I, dvs fungera som ändlägesstopp i båda vridriktningarna kring l. Bultarna 50 innefattar en tryckfjäder 51 i form av en spiralfjäder, vilken även kan utformas som ett av elastiskt material tillverkat cylinderformigt element, samt två brickor 52, 53. Varje bult 50 är försedd med en utanpåliggande gänga vid en ände över vilken en första bricka 52, fjädern 51 och en andra bricka 53, vilken fungerar som en distansbricka och glidbricka, träs innan bulten sedan förs igenom resp upphängningsanordnings 11 , 12 bakre hål och skruvas in i mothållets 20 gängade bottenhål medan fjädern 51 trycks ihop och till dess bulten 50 bottnar i hålet (i fig 6 visas bulten 50, fjädern 51 och brickoma 52, 53 i inskruvat läge utan upphängningsanordningarna 11, 12). Genom att dimensionera - brickornas 52, 53 tjocklek, fjäderns 51 och bultens 50 längd kan fjäderkraften optimeras så att mothållet 20 behåller sin senaste inställning relativt upphängningsanordningarna 11,12 såsom förinställning inför nästa förseglingsoperation.| det nya mothållsarrangemanget 10 är upphängningsanordningarna 11, 12 anpassade för rörelse i ett plan som är parallellt med mothållets 20 längdaxel l och huvudsakligen vinkelrätt mot förpackningarnas längd-/riktningsaxel och transportriktning (som i sin tur är parallell med vridningsaxeln L i fig 3) . Denna rörliga upphängning åstadkommes medelst två fjädrande mekanismer innefattande två separata, löstagbara pinnar eller bultar 70, som var och en är i gängingrepp med ett bottenhål i vardera upphängningsanordnings 11, 12 bakre del, och vilka sträcker sig vinkelrät mot mothållets 20 längdaxel l igenom ett helt ../T P 1548 SE - APPL - as amended after first office action.doc 528 D44 10 15 20 25 30 35 genom bärarmen 30 gående hål, vars innerdiameter är större än bultarnas 70 ytter- diameter (visas tydligt i fig. 3 och 5).The bolts 50 (see Figs. 3, 5 and 6) have the function of limiting the rotational movement of the abutment 20 about the longitudinal axis I, i.e. function as an end position stop in both directions of rotation about 1. The bolts 50 comprise a compression spring 51 in the form of a coil spring, which can also be formed as a cylindrical element made of elastic material, and two washers 52, 53. Each bolt 50 is provided with a surface-mounted thread at one end over which a first washer 52, the spring 51 and a second washer 53, which acts as a spacer and slide washer , threaded before the bolt is then passed through the rear holes of the respective suspension device 11, 12 and screwed into the threaded bottom hole of the anvil 20 while the spring 51 is compressed and until the bolt 50 bottoms in the hole (Fig. 6 shows the bolt 50, the spring 51 and the washers 52, 53 in the screwed-on position without the suspension devices 11, 12). By dimensioning the thickness of the washers 52, 53, the length of the spring 51 and the bolt 50, the spring force can be optimized so that the abutment 20 retains its latest setting relative to the suspension devices 11,12 as a preset for the next sealing operation. the new abutment arrangement 10, the suspension devices 11, 12 are adapted for movement in a plane parallel to the longitudinal axis 1 of the abutment 20 and substantially perpendicular to the longitudinal / directional axis and transport direction of the packages (which in turn is parallel to the axis of rotation L in Fig. 3). This movable suspension is effected by means of two resilient mechanisms comprising two separate, detachable pins or bolts 70, each of which is in threaded engagement with a bottom hole in the rear part of each suspension device 11, 12, and which extend perpendicular to the longitudinal axis 1 of the anvil 20 through an entire ../TP 1548 SE - APPL - as amended after first office action.doc 528 D44 10 15 20 25 30 35 holes passing through the support arm 30, the inner diameter of which is larger than the outer diameter of the bolts 70 (clearly shown in Figs. 3 and 5 ).

Bultarna 70 i de fjädrande upphängningsanordningarna som visas ifig. 5 är försedda med en utvändig gänga vid en ände och anpassade för att från bärarmens 30 baksida sträcka sig genom en första styrbricka 71, vilken har en mot bärarmen 30 vettande urtagning för upptagning av en ände av en tryckfjäder 72, här en spiralfjäder, och en distansbricka 73 genom bärarmen vidare ut genom bärarmens framsida som vetter mot mothållet 20 med sina gängade ändar och genom en andra styrbricka 74.The bolts 70 in the resilient suspensions shown in FIG. 5 are provided with an external thread at one end and adapted to extend from the back of the support arm 30 through a first guide washer 71, which has a recess facing the support arm 30 for receiving one end of a compression spring 72, here a coil spring, and a spacer 73 through the support arm further out through the front of the support arm facing the abutment 20 with its threaded ends and through a second guide washer 74.

Flesp bults 70 gängade ände är inskruvad i ett bottenhál i en ifig 5 visad mot bärarmen 30 vettande tapp som utskjuter från resp upphängningsanordning 11, 12. Den andra styrbrickan 74 anordnas utvändigt den utskjutande tappen på resp upphängnings- anordning 11, 12 och låses axiellt till denna medelst låspinnar 75, t ex fjäderpinnar.The threaded end of the flange bolt 70 is screwed into a bottom hole in a pin shown towards the support arm 30 projecting from the respective suspension device 11, 12. The second guide washer 74 is arranged externally to the projecting pin on the respective suspension device 11, 12 and is locked axially to this by means of locking pins 75, for example spring pins.

Láspinnarna är anpassade för ett glappande ingrepp med spår i resp utskjutande tapp genom att göra spåren l tappen något större än låspinnarna erfordrar så att en begränsad relativ rörelse tillåts mellan styrbricka 74 och tapp.The locking pins are adapted for a playful engagement with grooves in the respective projecting pin by making the grooves in the pin slightly larger than the locking pins require so that a limited relative movement is allowed between guide guide 74 and pin.

I fig. 3 visas monteringen av bultarna 70 där den första styrbrickan 71 som har ett genomgående häl först träs över bultens 70 gängade ände, vartefter fjädern 72 träs över bulten och förs in delvis med en ände i styrbrickans 71 urtagning och distansbrickan 73 träs över bulten 70 som förs vidare genom bärarmen 30 tills den sticker ut med sin gängade ände ur bärarmen. Den andra styrbrickan 74 träs över den på baksidan av resp upphängningsanordning 11, 12 utskjutande tapp och låses axiellt genom att föra in låspinnarna 75 i resp hål. Bulten 70 skruvas sedan in i upphängningsanordningens 11, 12 gängade bottenhål medan fjädern 72 trycks ihop till den bottnar i hålet. Genom att dimensionera brickans 73 tjocklek, fjäderns 72 och bultens 70 längd samt urtagningens djup i den första distansbrickan 71 kan fjäderkraften optimeras så att den ger ett lämpligt motstånd mot rörelse för mothållet 20 och upphängningsanordningarna 11, 12.Fig. 3 shows the mounting of the bolts 70 where the first guide washer 71 having a through heel is first threaded over the threaded end of the bolt 70, after which the spring 72 is threaded over the bolt and inserted partially with one end in the socket of the guide washer 71 and the spacer 73 is threaded over the bolt 70 which is passed through the support arm 30 until it protrudes with its threaded end from the support arm. The second guide washer 74 is threaded over the pin projecting on the back of the respective suspension device 11, 12 and is locked axially by inserting the locking pins 75 in the respective holes. The bolt 70 is then screwed into the threaded bottom hole of the suspension device 11, 12 while the spring 72 is compressed until it bottoms in the hole. By dimensioning the thickness of the washer 73, the length of the spring 72 and the bolt 70 and the depth of the recess in the first spacer 71, the spring force can be optimized so that it provides a suitable resistance to movement of the abutment 20 and the suspension devices 11, 12.

Bärarmens 30 genomgående hål för upptagning av bultarna 70 och tillhörande komponenter 71, 72, 73, 74, 75 har två principiellt lika öppningar som är utformade med en huvudsakligen fyrkantig form, en öppning pá bärarmens baksida som vetter ifrån mothållet 20 och en öppning på bärarmens framsida. Urtagningarna har en större bredd sett i mothållets 20 längdriktning I än höjd och är utformade för upptagning samt styrning av brickorna 71 och 74 som är åttkantiga, såsom visas i fig. 3, men kan även vara fyrkantiga eller uppvisa annan med urtagningarna samverkande form. Styrningen av upphängningsanordningarnas 11, 12 rörelse i ett plan som är parallellt med mothàllets 20 längdaxel l åstadkommas genom att brickornas 71, 74 höjd (se fig. 3) är så anpassad i tolerans till den inre höjden hos bärarmens fyrkantiga öppningar att brickorna anligger mot öppningarna ”tak” och "golv" och i princip inte tillåter någon vertikal rörelse för brickorna och upphängningsanordningarna 11, 12 samt mothållet 20. Urtagningarnas ../T P 1548 SE - APPL - as amended after first ottice action.doc 528 044 10 15 20 25 30 bredd är som sagt större än deras höjd medan brickorna 71, 74 är symmetriska, dvs har lika stor bredd som höjd, varvid ett spel åstadkommes mellan brickorna och öppningarnas sidor (visas tydligt i fig. 5) och innebär att en rörelse i ett plan som är parallellt med mothållets 20 längdaxel I tillåts om mothàllet 20t ex rör sig längre utåt med sin vänstra ände 20a jämfört med sin högra ände 20b.The through holes of the support arm 30 for receiving the bolts 70 and associated components 71, 72, 73, 74, 75 have two substantially equal openings which are formed with a substantially square shape, an opening on the back of the support arm facing away from the abutment 20 and an opening on the support arm front. The recesses have a larger width seen in the longitudinal direction I of the abutment 20 than height and are designed for receiving and guiding the washers 71 and 74 which are octagonal, as shown in Fig. 3, but can also be square or have another shape cooperating with the recesses. The control of the movement of the suspension devices 11, 12 in a plane parallel to the longitudinal axis 1 of the anvil 20 is effected by the height of the washers 71, 74 (see Fig. 3) being so adapted in tolerance to the inner height of the square arms of the support arm that the washers abut "Ceiling" and "floor" and in principle do not allow any vertical movement of the washers and suspension devices 11, 12 and the abutment 20. The recesses ../TP 1548 SE - APPL - as amended after first ottice action.doc 528 044 10 15 20 25 Width is as stated greater than their height while the washers 71, 74 are symmetrical, i.e. have the same width as height, whereby a clearance is created between the washers and the sides of the openings (clearly shown in Fig. 5) and means that a movement in a plane which is parallel to the longitudinal axis I of the anvil 20 is allowed if the anvil 20t, for example, moves further outwards with its left end 20a compared to its right end 20b.

Mothàllsarrangemanget 10 enligt uppfinningen är även försett med en rundad bricka 80 (se fig. 2, 3 och 6) som är löstagbart ansluten till mothållets 20 översida och anpassad för att i sidled stödas av ett urtag i en vid bärarmen 30 fast anordnad klack 81.The abutment arrangement 10 according to the invention is also provided with a rounded washer 80 (see Figs. 2, 3 and 6) which is releasably connected to the upper side of the abutment 20 and adapted to be laterally supported by a recess in a lug 81 fixedly attached to the support arm 30.

Denna bricka 80 är formanpassad med sin radie så att den kan ”rulla” eller vridas något inuti urtaget och följa med mothàllet 20 något under dess rörelse samtidigt som den eliminerar eventuella ”byrålådseffektei” då mothàllet rör sig från/mot bärarmen 30 och samtidigt vrider sig något. Denna styrning i sidled medelst brickan 80 och klackens 81 urtag ger en extra stabilitet för mothållsarrangemanget 10 i mothâllets 20 längdriktning l.This washer 80 is shaped with its radius so that it can "roll" or rotate slightly inside the recess and follow the abutment 20 slightly during its movement while eliminating any "drawer effect" as the abutment moves from / to the support arm 30 and at the same time rotates something. This lateral guide by means of the washer 80 and the recess of the lug 81 provides an additional stability for the abutment arrangement 10 in the longitudinal direction 1 of the abutment 20.

Mothållets 20 ändar 20a, 20b är i kontakt med upphängningsanordningarna 11, 12 medelst friktionsytor 60 i form av löstagbara friktionsbelägg/-inlägg (visas i tig. 2, 3, 5- 7). Dessa friktionsinlägg 60 uppvisar i föreliggande utföringsform även vibrationsdämpande egenskaper för dämpning av den högfrekventa vibration som ultraljudhornet tillför mothàllet 20.The ends 20a, 20b of the abutment 20 are in contact with the suspension devices 11, 12 by means of friction surfaces 60 in the form of removable friction pads / inserts (shown in Figs. 2, 3, 5-7). In the present embodiment, these friction inserts 60 also have vibration damping properties for damping the high-frequency vibration which the ultrasonic horn supplies to the abutment 20.

Genom att anordna dessa friktionsinlägg 60 mellan mothàllet 20 och upphängningsanordningarna 11, 12 ges i samverkan med fjäderkrafterna en själv- justerande funktion för mothållsarrangemanget 10 i och med att mothàllet 20 kan vrida/ställa in sig med sin förseglingsyta genom vridning kring sin längdaxel I efter riktningen alt orienteringen för motsvarande förseglingsyta på ultraljudhornet 13 vid försegling av förpackningarna och därefter bibehällas eller kvarhållas i detta läge då friktionen mellan mothàllet 20, friktionsytorna 60 och upphängningsanordningarna 11, 12 justerbart ”låser” i senaste läget. "Hoplåsningen" övervinns av snedbelastningar. Denna självjusteringsfunktion innebär att mothàllet 20 ”automatiskt” och utan hjälp åstadkommer finjusteringen av mothàllet efter värmebacken förutsatt att mothàllet vid montering efter förmåga justerats in. Naturligtvis kompenseras även för awikelseri materialtjocklek.By arranging these friction inserts 60 between the abutment 20 and the suspension devices 11, 12, in co-operation with the spring forces, a self-adjusting function is provided for the abutment arrangement 10 in that the abutment 20 can rotate / adjust with its sealing surface by rotating about its longitudinal axis I in the direction or the orientation of the corresponding sealing surface on the ultrasonic horn 13 when sealing the packages and then maintained or retained in this position when the friction between the abutment 20, the friction surfaces 60 and the suspension devices 11, 12 adjustably "locks" in the last position. The "lock-in" is overcome by skewed loads. This self-adjusting function means that the abutment 20 "automatically" and without assistance achieves the fine adjustment of the abutment after the heating jaw, provided that the abutment during installation has been adjusted according to ability. Of course, material thickness is also compensated for deviations.

Detta minskar mängden manuellt arbete för kalibrering och omjusteringar av mot- hållets orientering, förbättrar förseglingen av förpackningen och förseglingsprocedurens repeterbarhet. .frP 1548 SE - APPL - as amended after first office actiondocThis reduces the amount of manual work for calibration and re-adjustments of the resistance orientation, improves the sealing of the package and the repeatability of the sealing procedure. .frP 1548 SE - APPL - as amended after first office actiondoc
