Den foreliggende opfindelse angår en fremgangsmåde og et apparat til lukning af emballager med låg og af den i indledningen til krav 1 henholdsvis krav 2 angivne art. I denne sammenhæng skal især omtales lukning af bægre eller kræmmerhuse indeholdende eksempelvis iscreme.The present invention relates to a method and apparatus for sealing packages with lids and of the kind specified in the preamble of claim 1 and claim 2, respectively. In this context, in particular, mention should be made of the closure of cups or cream houses containing, for example, ice cream.
Fra US patentskrift nr. 2.934.872 kendes et apparat til jj lukning af en emballage ad gangen. Fremføringen i dette ap- r- parat af et låg ad gangen giver ikke anledning til de proble- mer, som opstår, når flere emballager skal lukkes samtidig, d" Fremføring af flere låg i form af en sammenhængende strimmel % kræver, at disse låg stabiliseres og fastholdes i passende stilling i forhold til den modtagende emballage i den periode, ιέUS Patent No. 2,934,872 discloses an apparatus for closing one package at a time. The feeding in this unit of one lid at a time does not give rise to the problems that arise when several packages must be closed at the same time. "The feeding of several lids in the form of a coherent strip% requires that these lids stabilized and maintained in the appropriate position in relation to the receiving packaging during the period ιέ
DD
144061 - 2 - hvor lågene tildannes og påsættes emballagerne. Ved den enkeltvise fremføring giver dette ingen anledning til problemer, da låget hænger sammen med enden af en strimmel. Strimlen giver i sig selv den nødvendige stabilitet i det øjeblik, låget fjernes fra strimlen og omgående påsættes emballagen.144061 - 2 - where the lids are formed and affixed to the packaging. In the case of single feeding, this does not cause any problems as the lid is connected to the end of a strip. The strip itself provides the necessary stability the moment the lid is removed from the strip and the packaging is immediately applied.
Det er indlysende, at ved påsætning af flere låg vil den samtidige operation, hvad angår hvert enkelt låg, medføre, at disse låg ikke kan stabiliseres og understøttes af strimlen, der senere føres ind i apparatet.It is obvious that by applying multiple lids, the simultaneous operation with respect to each lid will cause these lids to not be stabilized and supported by the strip which is subsequently inserted into the apparatus.
Fra DE offentliggørelsesskrift nr. 2.344.929 kendes et apparat til lukning af emballager, hvor lågstrimlen fastholdes langs kanterne af to klemmeplader, medens lågene fraskæres og påsættes emballagemundingerne. Skæreorganeme består af en skærering, i hvilken et koaksialt forskydeligt lukkehoved påsætter det fraskårne låg uden nogen form for stabilisering. Skæreringen virker herved som en føringsbakke for de to klemplader, gennem hvilken den indretning, som påsætter lågene, arbejder. En stabilisering er unødvendig, da snit-kraften kan fordeles ensartet langs snitlinien. Dette er derimod ikke tilfældet ved en langstrakt lågstrimmel, der skal overskæres på tværs og derfor nødvendiggør organer til fastholdelse af strimlen irnder skæreprocessen.DE disclosure no. 2,344,929 discloses an apparatus for closing packages where the lid strip is held along the edges by two clamping plates while the lids are cut off and the packaging orifices are attached. The cutting means consist of a cutting ring in which a coaxially displaceable closure head attaches the cut-off lid without any stabilization. The cutting ring hereby acts as a guide tray for the two clamping plates through which the device which attaches the lids works. Stabilization is unnecessary as the cutting force can be distributed evenly along the cut line. This, on the other hand, is not the case for an elongated cover strip which must be cut transversely and therefore necessitates means for holding the strip during the cutting process.
Formålet med den foreliggende opfindelse er at anvise en fremgangsmåde til samtidig lukning af flere emballager med låg uden behov for en særlig klemmeindretning til fastholdelse • af lågstrimlen.The object of the present invention is to provide a method for simultaneously closing multiple packages with lids without the need for a special clamping device for holding the lid strip.
Dette opnås ifølge opfindelsen ved, at strimlen fastholdes i såvel side- som længderetning, idet man anvender knivblade med en spids til at spidde strimlen mellem nabolåg, og at lågene adskilles fra hinanden, ved at strimlen overskæres fra midten ud mod begge langsider, hvorved de under afskæring værende låg samtidig forskydes vinkelret på strimlen og efter fuldstændig adskillelse fra denne presses ind i emballagemundingerne .This is achieved according to the invention by holding the strip in both side and longitudinal directions, using knife blades with a tip to split the strip between neighboring lids, and separating the lids apart by cutting the strip from the middle towards both long sides. at the same time, when the lid is cut off, it is displaced perpendicular to the strip and after complete separation from it is pressed into the packaging orifices.
Ved denne fremgangsmåde er særlige stabiliseringsorganer overflødige, fordi skæreorganerne, knivbladene, stabiliserer og fastholder lågene i passende stilling i forhold til emballagerne, medens lågene tildannes og påsættes.In this method, special stabilizing means are superfluous because the cutting means, knife blades, stabilize and hold the lids in a suitable position relative to the packages while the lids are formed and applied.
144061 - 3 -144061 - 3 -
Opfindelsen angår som nævnt også et apparat til udøvelse af fremgangsmåden og med bæreorganer for emballager, hvis mundinger skal isættes låg, organer til at fremføre en lågstrimmel, indtil der findes et låg over hver emballage, samt organer til at overskære strimlen til adskillelse af de enkelte låg og til at presse disse ind i emballagemundingerne. Ifølge opfindelsen foreslås, at skæreorganerne omfatter knivblade med en central spids, der er indrettet til at kunne ramme og gennembore strimlen på midten, og med bort fra spidsen skråt bagud i spidsens længderetning forløbende skærekanter på hver side af spidsen for gradvis overskæring af strimlen fra midten ud mod kanterne.The invention also relates, as mentioned, to an apparatus for carrying out the method and with carrier means for packages whose mouths are to be inserted lid, means for advancing a lid strip until a lid is provided over each package, and means for cutting the strip to separate the individual lids and to press them into the packaging orifices. According to the invention it is proposed that the cutting means comprise knife blades with a central tip arranged to strike and pierce the strip in the middle, and with cutting edges extending longitudinally of the tip, extending cutting edges on each side of the tip for gradual cutting of the strip from the center towards the edges.
Opfindelsen skal i det følgende forklares nærmere i forbindelse med tegningen, hvor fig. 1 viser den væsentlige del af et apparat ifølge opfindelsen, set fra siden, fig. 2 samme set fra oven, fig. 3 et snit langs linien 3-3 i fig. 1, fig. 4 i større målestoksforhold og med visse dele fjernet venstre del af det i fig. 1 viste, fig. 5 et snit langs linien 5-5 i fig. 4, fig. 6 et snit langs linien 6-6 i fig. 4, fig. 7 et snit langs linien 7-7 i fig. 4, fig. 8 et snit langs linien 8-8 i fig. 3, fig. 9 et snit langs linien 9-9 i fig. 4, fig. 10 et snit langs linien 10-10 i fig. 9, fig. 11 et snit langs linien 11-11 i fig. 7, fig. 12 et snit langs linien 12-12 i fig. 11, fig. 13 et snit langs linien 13-13 i fig. 11, fig. 14 et snit langs linien 14-14 i fig. 1, og fig. 15 et lodret snit gennem det i fig. 14 viste stempel i dettes nederste endestilling.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail in connection with the drawing, in which: FIG. 1 is a side view of the essential part of an apparatus according to the invention; FIG. 2 shows the same from above; FIG. 3 is a section along the line 3-3 of FIG. 1, FIG. 4 in larger scale and with some parts removed the left part of the one shown in FIG. 1; FIG. 5 is a section along line 5-5 of FIG. 4, FIG. 6 is a sectional view taken on line 6-6 of FIG. 4, FIG. 7 is a sectional view taken along line 7-7 of FIG. 4, FIG. 8 is a sectional view taken along line 8-8 of FIG. 3, FIG. 9 is a sectional view taken along line 9-9 of FIG. 4, FIG. 10 is a sectional view taken along line 10-10 of FIG. 9, FIG. 11 is a sectional view taken along line 11-11 of FIG. 7, FIG. 12 is a sectional view taken along line 12-12 of FIG. 11, FIG. 13 is a sectional view taken along line 13-13 of FIG. 11, FIG. 14 is a sectional view taken along line 14-14 of FIG. 1, and FIG. 15 is a vertical section through the embodiment of FIG. 14 in its lower end position.
Det tydeligst i fig. 1-4 viste apparat 20 samvirker med transportorganer 25, der successivt fremfører tværgående rækker af emballager såsom bægre eller som her kræmmerhuse C (fig. 15), hvis opadvendte åbning i apparatet skal lukkes ved hjælp af papir- eller paplåg P. Kræmmerhusene C bæres af bøsningsformede sokler 21, der er anbragt i tværgående rækker 1U061 - 4 - mellem eksempelvis transportkæder, som intermitterende bringer en sokkelrække ind i apparatet 20. Apparatet 20 omfatter en tværgående række af kombinerede skære-, forme- og lukkestempler 22 i et antal lig med antallet af sokler 21 i hver række. Ved den viste udførelsesform er dette antal seks. Kræmmerhusene C er, inden de når apparatet 20, fyldt med eksempelvis iscreme, men apparatet 20 kan naturligvis benyttes til at lukke andre former for emballage med paplåg.Most clearly in FIG. 1-4, the apparatus 20 cooperates with conveying means 25, which successively convey transverse rows of packages such as cups or, as here, cage houses C (Fig. 15), whose upward opening in the apparatus is to be closed by means of paper or cardboard cover P. The cage houses C are carried. of bush-shaped pedestals 21 arranged in transverse rows 1U061-4, for example, between transport chains which intermittently bring a pedestal row into the apparatus 20. The apparatus 20 comprises a transverse row of combined cutting, molding and closing pistons 22 in a number equal to the number of sockets 21 in each row. In the embodiment shown, this number is six. Before they reach the appliance 20, the appliance housings C are filled with, for example, ice cream, but the appliance 20 can of course be used to close other types of packaging with cardboard lids.
Paplågene P tilføres apparatet 20 fra en lagerrulle med en sammenhængende strimmel 30 af indbyrdes forbundne låg, der her er ottekantede og sammenhængende langs den ene kant. Mellem på hinanden følgende låg findes på modstående sider V-for-mede indsnit 31 (se fig. 9), der også udgør fremføringsmarkeringer for en føderulle 35.The cardboard covers P are supplied to the apparatus 20 from a storage roll with a continuous strip 30 of interconnected lids which are here octagonal and continuous along one edge. In between successive lids are found on opposite sides V-shaped incisions 31 (see Fig. 9), which also constitute feed marks for a feed roller 35.
Føderullen 35 har langs sin periferi knaster 36 for samvirke med indsnittene 31, således at rullen kan trække strimler 30 af den ikke viste lagerrulle og fremføre den trinvist således, at et til rækken af sokler 21 svarende antal låg P indføres i apparatet ad gangen.The feed roll 35 along its periphery has knobs 36 for cooperating with the incisions 31, so that the roll can pull strips 30 of the bearing roll not shown and feed it incrementally so that a number of lids P corresponding to the row of sockets 21 are introduced into the apparatus at a time.
Papirstrimlen 30 skubbes af fødehjulet 35 ind i lede- og skæreorganer 40, der strækker sig tværs over transportorganerne 25 lige over soklerne 21. Lede- og skæreorganerne omfatter en støttebro 41, der hviler på bukke 42 på hver side af transportorganeme. Bukkene 42 bæres af apparatets chassis 43. Når strimlen 30 forlader føderullen 35, passerer den • over et glidestyr 44 (fig. 4), der hviler på og er fastgjort til broen 41 og chassiset 43. Giidestyret 44 har på oversiden en langsgående slids 45, hvis bredde overstiger en tredjedel af strimlens 30 bredde. Strimlen 30 trykkes ned i slidsen af en trykbom 46. Denne er fastgjort til glidestyret 44 ved hjælp af et oplukkeligt spændeorgan 47, så at den kan fjernes og dermed lette indføring af strimmelenden. Nær spændeorga-net bærer trykbommen 46 en opadrettet beskyttelsesplade 48, der skal hindre adgang for den person, der betjener spænde-organet, til en nærstående kniv 61. Ved forkanten har trykbommen 46 en styrefinger 49, der rager ind i en slids 50 (fig. 3) i føderullens 35 periferi. Forkanten 51 af styret 44 er skråt afskåret, således at der mellem styret og fingeren 49 dannes en tragtformet indføringsåbning 52 for strimlen - 5 - 144061 30. Trykbommen 46 har, som vist i fig. 6, ved de langsgående kanter nedadrettede ribber 53, de^ samvirker med udskæringer i kanterne af glidestyret 44, og på midten en langsgående ribbe 55, der rager ned i glidestyrets 44 slids 45.The paper strip 30 is pushed by the feed wheel 35 into guide and cutting means 40 extending across the conveying means 25 just above the bases 21. The guide and cutting means comprise a support bridge 41 resting on the buckets 42 on each side of the conveying means. The buckets 42 are carried by the chassis 43 of the apparatus. As the strip 30 exits the feed roller 35, it passes over a slide guide 44 (Fig. 4) which rests on and is attached to the bridge 41 and the chassis 43. The guide guide 44 has a longitudinal slot 45 on the upper side. , the width of which exceeds one-third of the width of the strip 30. The strip 30 is pressed down into the slot of a thrust bar 46. This is secured to the slide guide 44 by a retractable clamping means 47 so that it can be removed and thereby facilitate insertion of the strip end. Near the clamping member, the thrust bar 46 carries an upwardly guarding plate 48 to prevent access by the person operating the clamping member to a related knife 61. At the leading edge, the thrust bar 46 has a guide finger 49 projecting into a slot 50 (FIG. 3) in the circumference of the feed roll 35. The leading edge 51 of guide 44 is obliquely cut so as to form between the guide and finger 49 a funnel-shaped inlet port 52 for the strip - 5 - the pressure bar 46 has, as shown in FIG. 6, at the longitudinal edges, downwardly directed ribs 53 cooperate with cut-outs at the edges of the slide guide 44, and in the middle a longitudinal rib 55 projecting into the slot 45 of the slide guide 44.
Inden strimlen 30 når ind over soklerne 21, forlader den glidestyret 44. I forlængelse af glidestyr og trykbom er, som det fremgår af fig. 8,9, på støttebroen 41 fastgjort en skæreplade 56. På denne er fastgjort to langsgående, parallelle glidelister 57, og på hver af disse endnu en liste 58. Ved den øverste, mod den anden liste vendte kant på glidelisteme 57 findes en nedskæring eller rille 59 i hele listens længde. De to riller 59, der opad afgrænses af listen 58, tjener til at fastholde og styre de langsgående kanter af strimlen 30. Ved indløbet til rillerne 59 er den øverste liste 58 skråt afskåret, således at der dannes det i fig. 8 viste gab 65.Before the strip 30 reaches over the bases 21, it leaves the slide guide 44. By extension, the slide guide and thrust boom are as shown in FIG. 8,9, a cutting plate 56 is attached to the support bridge 41. Two longitudinal parallel sliding strips 57 are attached thereto, and on each of these a further strip 58. At the upper edge of the sliding strips 57 facing the second strip is a cut or groove 59 throughout the length of the molding. The two grooves 59, which are bounded upwardly by the strip 58, serve to hold and guide the longitudinal edges of the strip 30. At the inlet to the grooves 59, the upper strip 58 is obliquely cut to form the one shown in FIG. 8 shown 65.
I glidestyrets 44 rille 45 hvælves strimlen 30 af trykbommens ribbe 55. Når strimraelkanterne gribes i rillerae 59, opretholdes den hvælvede form, fordi listernes 57 afstand er passende mindre end strimlens 30 bredde.In the groove 45 of the slide guide 44, the strip 30 is curved by the rib 55 of the thrust bar. When the strip rim edges are gripped in the grooves 59, the vaulted shape is maintained because the distance of the strips 57 is suitably less than the width of the strip 30.
Over hver sokkel 21 findes i lede- og skæreorganerae 40 lodrette passager 70, over hvilke er anbragt stemplerne 22 med lukkehoveder 60, der kan bevæges op og ned gennem passagerne 70. Under hver passage 70 er til broen 41 fastgjort et mellemstykke 71 med modstående styreflanger 72, der strækker sig på tværs af broen 41. Styreflangerne har, som vist i fig, 13, indad og nedad skrånende underflader, dvs. de flader, der vender mod hinanden i forlængelse af en passages 70 væg.Above each socket 21 are vertical passages 70 in the guide and cutting members 40, over which are arranged the pistons 22 with closing heads 60, which can be moved up and down through the passages 70. During each passage 70, an intermediate piece 71 is provided with opposite guide flanges 72 extending across the bridge 41. As shown in Fig. 13, the guide flanges have inwardly and downwardly sloping sub-surfaces, i.e. the faces facing each other in extension of a passage's 70 wall.
Regnet i strimlens 30 fremføringsretning er der foran hver passage 70 i skærepladen 56 og støttebroen en bladslids eller passage 75 for et med lukkehovederae 60 bevægeligt knivblad 61.Calculated in the direction of advance of the strip 30, in front of each passage 70 in the cutting plate 56 and the supporting bridge, there is a blade slot or passage 75 for a knife blade 61 movable with the closing head 60.
I fig. 11 er vist, hvorledes de strimlen 30 ledende slidser 59 afsluttes ved et ågformet stoporgan 76, hvis mod strimlen vendte flader omslutter de tre fremadvendte af det forreste lågs P otte kanter. Stoporganet 76 er fastgjort til skærepladen 56 og ligger lavere end slidserne 59. På den modsatte side af den sidste passage 70 er anbragt et par modstående, trekantede holdeorganer 77, der er således anbragt, at de sva- t 144061 - 6 - rer til det forreste sæt af udskæringer 31 i strimlen 30.In FIG. 11 is shown how the conductive slits 59 of the strip 30 are terminated by an yoke-shaped stop member 76 whose faces facing the strip surround the three forward faces of the eight edges of the front cover P. The stop member 76 is attached to the cutting plate 56 and is lower than the slits 59. On the opposite side of the last passageway 70 are placed a pair of opposing triangular holding means 77 which are positioned so that they are closed to it. front set of cutouts 31 in strip 30.
Holdeorganerne 77 er fastgjort til skærepladen 56 og beliggende lavere end slidserne 59. Stop- og holdeorganernes 76,77 funktion vil blive nærmere omtalt i det følgende.The holding means 77 are attached to the cutting plate 56 and located lower than the slots 59. The operation of the stopping and holding means 76,77 will be discussed in more detail below.
Skære-, forme- og lukkestempierne 22 er ophængt over soklerne 21 i en tværgående bro 80. Denne bro 80 kan hæves og sænkes synkront med strimmelfremføringen i forhold til støtter 81 på modstående sider af transportorganerne 25·The cutting, forming and closing pistons 22 are suspended over the bases 21 in a transverse bridge 80. This bridge 80 can be raised and lowered synchronously with the strip feed relative to supports 81 on opposite sides of the conveying means 25
Fig. 14 og 15 viser mere detaljeret et af stemplerne 22, der omfatter et rørformet stempellegeme 85, der kan glide ak-sialt, men ikke dreje i en lejekrave 86, der er fastgjort på tindersiden af broen 80. Den aksiale bevægelse opad begrænses af en flange 87 på stempellegemet. Den øverste ligeledes rørformede del af stemplet har større diameter og passer glidende i en bøsning 88 i broen 80. Overgangen eller kanten mellem stempellegemet 85 og den øverste del udgør et anlæg 89, der trykkes mod lejekravens 86 overside af en fjeder 90, der er indspændt mellem overgangen i stemplets indre og en hætte 91» der er fastgjort øverst i bøsningen 88. Når anlægget 89 ligger an mod kraven 86, er der mellem stemplets 22 overside og hætten 91 et rum 92, der tillader begrænset hævning af stemplet op i broen mod fjederens 90 kraft.FIG. 14 and 15 show in more detail one of the pistons 22 comprising a tubular piston body 85 which can slide axially but not rotate in a bearing collar 86 secured to the tinder side of the bridge 80. The axial upward movement is limited by a flange. 87 on the piston body. The upper likewise tubular portion of the piston has a larger diameter and fits slidably into a sleeve 88 of the bridge 80. The transition or edge between the piston body 85 and the upper portion constitutes a abutment 89 pressed against the upper surface of the bearing collar 86 by a spring 90 which is clamped between the transition in the interior of the piston and a cap 91 'which is fixed at the top of the sleeve 88. When the abutment 89 abuts against the collar 86, between the upper side of the piston 22 and the cap 91 there is a space 92 which permits limited raising of the piston in the bridge towards spring force 90.
På den nederste del af stemplet er lukkehovedet 60 fastgjort aftageligt. Lukkehovedet har nederst en indadskrånende ringformet lukkeflade 95 for samvirke med den tilsvarende skrålende underflade 96 i soklen 21.On the lower part of the plunger, the closure head 60 is removably removable. The closure head has at the bottom an inwardly sloping annular closure surface 95 for co-operation with the corresponding sloping bottom surface 96 of the base 21.
I det rørformede stempellegeme 85 er anbragt et elektrisk varmelegeme 97.An electric heating element 97 is arranged in the tubular piston body 85.
De tidligere nævnte, hver med sit stempel bevægelige, knivblade 61 er, som vist i fig. 7, udformet med en spids 100, hvormed strimlen 30 fastholdes mod videre bevægelse, inden knivbladets skærekanter 101 skiller låget P fra strimlen 30.The aforementioned knife blades 61, each movable with its piston, are as shown in FIG. 7, formed with a tip 100, by which the strip 30 is held against further movement before the cutting edges 101 of the knife blade separate the lid P from the strip 30.
Apparatet virker på følgende måde:The device works as follows:
De fyldte bægre eller kræmmerhuse C fremføres i rækker placeret i soklerne 21, til mundingerne 96 befinder sig under passagerne 70 og stemplerne 22. Føderullen 35 vil samtidig fremføre en så lang del af strimlen 30, at der over hver pas- 1U061 - 7 - sage 70 findes et låg P. Under fremføringen er strimlen, som vist bl.a. i fig. 5 og 7 , nedadhvælvet, hvilket virker afstivende. Når der findes et låg P over hvert kræmmerhus C, bevæges stemplerne 22 nedad. Herved vil knivbladenes 6l spids 100 spidde og fastholde strimlen,' og skærekanteme 101 vil adskille de enkelte låg, når stemplerne fører materialet mod skærepladen 56 og ud af indgreb mod slidserne 59* Under stemplets 27 yderligere nedadgående bevægelse vil lukkehovedet 60 blive ført gennem passagen 70 medbringende et låg P.The filled cups or creamer houses C are fed in rows located in the bases 21 until the orifices 96 are below the passages 70 and the pistons 22. The feed roll 35 will simultaneously feed such a long portion of the strip 30 that over each passageway 70, there is a lid P. During feeding, the strip, as shown, i.a. in FIG. 5 and 7, downward vault, which appears to be stiffening. When a lid P is found above each crankcase C, the pistons 22 are moved downward. Hereby, the tip 100 of the knife blades 6l will pin and hold the strip, and the cutting edges 101 will separate the individual lids as the pistons guide the material toward the cutting plate 56 and out of engagement with the slits 59 * During further downward movement of the piston 27, the closing head 60 will be passed through the passage 70 carrying a lid P.
Låget vil herved blive bibragt opadrettede kantflanger F (fig. 15). Når låget videre føres ned i kræmmerhusets C munding, vil flangerne F blive trykket mod kræmmerhusets indvendige væg ved mundingen af de samvirkende skrå flader 95 og 96. Da lukkehovedet 60 indeholder varmelegemet 97, kan der samtidig opnås en varmeforsegling af kræmmerhuset.The lid will thereby be provided with upward edge flanges F (Fig. 15). Further, when the lid is inserted into the mouth of the body housing C, the flanges F will be pressed against the inner wall of the body housing at the mouth of the cooperating oblique faces 95 and 96. As the closing head 60 contains the heater 97, a heat seal of the body body can be obtained simultaneously.
