Anordning for ftstadkonnnande av bigar i papp. Device for fastening of piglets in cardboard.

Vid framstallning av pappemballage, car sidorna bilda vinkel med varandra, fir det .erforderligt att fore papparkets vikning Horse detsamma med s. k. bigar, d. v. s. ratliniga inpressningar i arket, efter -vilka inpressningar emballagesidorna sedan vikas. For ett emballage av normal fyrkantform fordras vanligen, att papparket forses med fyra parallella bigar i en riktning och atminstone tva sinsemellan parallella bigar -vinkelratt daremot. Det foreligger emellertid stora svarigheter att astadkomma fullgoda bigar tjock papp utan att denna brister, och svarigheterna okas 1 mycket hog grad, da vid maskinell frarnstallning ett flertal parallella bigar skola samtidigt framstallas i pappen. En vasentlig orsak hartill ãr pappens ringa tanjbarhet, som medfor pappens bristning vid bigen, da det momentana intryckningsdjupet for bigen overstiger en viss grans. Foreliggande uppfinning undanrojer dessa svarigheter on mojliggor en samtidig fromstallning av ett flertal parallella fullgoda aven i tjock papp. Anordningen_ hanfor sig till det slag, (1.5.r papparket valsas i bigens langdriktning mellan samverkande med spar och kam forsedda bighjul och tva eller Tiera bighjulspar aro anordnade i bredd med varandra for astadkommande av paralle116- pande bigar, och uppfinningen kannetecknas i huvudsak darav, att fOr papparliets inellanpartier mellan bighjulsparen aro anordnade fOrstallda styranordningar for pappen med resp. styranordning bestftende av styrorgan, exempelvis en eller Hera styrrullar eller styrrullpar, i sadant lage, att resp. mellanparti av pappen halles uthojd i forhallande till bighjulsparens valsningslinje. When making cardboard packaging, the car sides form an angle with each other, for which it is necessary to line the cardboard folding Horse the same with so-called bigar, i.e. straight-line indentations in the sheet, after which impressions the packaging sides are then folded. For a package of normal square shape, it is usually required that the cardboard sheet be provided with four parallel piglets in one direction and at least two mutually parallel piglets - at right angles. However, there are great responsibilities for achieving sufficient piglets thick cardboard without this deficiency, and the responsibilities are increased to a very high degree, since in mechanical production a number of parallel piglets must be produced in the cardboard at the same time. A significant reason for this is the cardboard's poor extensibility, which causes the cardboard to rupture at the piglet, as the instantaneous depth of indentation of the piglet exceeds a certain limit. The present invention obviates these similarities and enables the simultaneous production of a plurality of parallel good deeds in thick cardboard. The device is of the type (1.5.r the cardboard sheet is rolled in the longitudinal direction of the beehive between cooperating beetles with ridges and ridges and two or Tiera beehive pairs are arranged in width with each other to produce parallel beehives, and the invention is mainly characterized therefrom, that for the inner parts of the paperboard between the pairs of spare wheels there are arranged guide devices for the cardboard with the respective guide device consisting of guide means, for example one or two guide rollers or guide roller pairs, in such a way that the respective intermediate part of the cardboard is held out in relation to the roller wheel pair.

De Iva bighjulen i resp. par Oro stallbara mot och Iran varandra. Darvid Or med fordel del ena bighjulet 2 (4) anordnat for groyinstallning och det andra 1 (3 far fininstallning. Anordningen for grovinstallning bestar sasom framgar ay fig. 3, att den axeltapp 6, 0 vilken bighjulet 2 Or anbragt, ar utformad med en excenter 36, 0 vilken big- hjulet Or frilopande lagrat.axeltappen yrides till olika yridlagen i sladen 9a medelst ett handtag 37, kommer bighjulets centrumlage att forandras, och bighjulet blir forstfillt narmare eller langre ifran det andra bighjulet i bighjulsparet. Anordningen for fininstallning Or likartad grovinstallningen med den skillnad, att handtaget 37 Or ersatt av en vid axeltappen 6 fast, racliellt utrackande by-gel 38, mellan yars skanklar en excenterskiya 39 Or fOrlagd, vridbar 0 en i sladen fast tapp. Genom excenterskiyans vridning for-shines bygeln och armed bighjulets excenter 36, varvid de samyerkande excenterrOrelserna medfora bighjulets fininstallning. The Iva bighjulen in resp. couple Concerns stackable against and Iran each other. In this case, it is advantageous for one part 2 (4) arranged for groy installation and the other 1 (3 for fine installation. The device for coarse installation consists, as can be seen in Fig. 3, that the axle pin 6, 0 which the bevel 2 Or is arranged, is formed with a eccentric 36, 0 which the big wheel Or is freely stored. the coarse installation with the difference that the handle 37 Or is replaced by a bracket 38 which is fixed at the shaft pin 6, between the yars an eccentric ski 39 Or is positioned, rotatable 0 a pin fixed in the sled. the eccentric of the big wheel 36, the co-operating eccentric movements entail the fine installation of the big wheel.

Del Or av stor vikt, att de samyerkande bighjulens kam 40 och spar 41 aro mycket noggrant avpassade .efter pappens tjockleht. Aven en ytterst ringa feldimensionering i detta hanseende medfor pappens bristling vid bigen pa grund av pappens ringa tanjbarhet. For att oyerkomma denna svarighet och samtidigt anpassa bighjulen for papp av olika tjocklek Or i utforingsformen enligt fig. 4 det highjul, som Or avsett for sparet, utford av hO gentemot varandra stallbara skivor 42, 43, som bilda mellan sig ,ett reglerbart mellanrum 41a, motsvarande sparet. Del liar vi-sat sig, att sparet darvidlag kan utan olagenhet sakna botten. Skivinstallningsanordningen kan vara utford pa olika salt, i den exemplifierade utforingsformen Or vid skivan 42 fast en gangad bussning 44, som eventuellt Icon yara fast anbragt vid kedjehjulet 19a, pa yilken bussning skivan 43 Or pagangad °eh hallen i installningslaget ay en stoppmutter 45 lampligen med annan gangning an skivans. Part Or of great importance, that the cam 40 and grooves 41 of the co-operating bevel wheels are very carefully adapted to the thickness of the cardboard. Even an extremely small incorrect dimensioning in this respect causes the cardboard to rupture at the blade due to the cardboard's poor extensibility. In order to overcome this liability and at the same time to adapt the cardboard wheels for cardboard of different thicknesses Or in the embodiment according to Fig. 4 the high wheel, which Or intended for the spare, is challenged by hO mutually stackable discs 42, 43, which form between them, an adjustable space 41a , corresponding to the savings. Del liar vi-sat sig, that the savings thereby can without illegality lack the bottom. The disc installation device can be challenged on different salts, in the exemplary embodiment Or at the disc 42 fixed a fixed bushing 44, which possibly Icon yara fixedly attached to the sprocket 19a, on which bushing the disc 43 Or attached to the hall in the installation layer ay a stop nut 45 suitably with another walk on the disc.

Bigarnas framstallning I pappen tillgar pa foljande satt. The representation of the bees in the cardboard adds in the following way.

Fran arkavskiljningsverket 30, dar at till ratt format skuret pappark avskiljes Iran en arkhog, frammatas papparket 5 medelst matarverket 27 fram mot de roterande samverkande bighjulen 1, 2, mellan vilka bighjul bigen yalsas in i pappen genom att kammen i bighjulet 1 under hjulens rotation inpressar den mellanliggande pappen i motsyarande, spar I bighjulet 2. Den harlid bildade bigen blir i den exemplifierade maskinen invalsad till endast en del av silt slutgiltiga djup, varafter bigen fullbordas genom fortsatt valsning vid (let efterliggande bighjulsparet 3, 4. Darigenom aft bigen sa sueeessivt formas und-vikes pappens bristling I bigen. From the sheet separator 30, where a sheet pile is cut into straight-cut cardboard, Iran is fed the sheet 5 by means of the feeder 27 towards the rotating cooperating bevel wheels 1, 2, between which bevel wheels the bevel is rolled into the cardboard by pressing the cam in the bevel wheel 1 during wheel rotation. the intermediate cardboard in the opposite, saves In the bevel 2. The harlid formed beehive is rolled in the exemplified machine to only a part of the silt final depth, after which the beehive is completed by further rolling at (let the beetle trailing pair 3, 4. Thus aft the beehive said sueeessively formed avoids cardboard bristling I bigen.

Detta fOrfaringssatt Or emellertid endast mOjligt vid ej alltfiir stort djup 0 bigen. For att lzunna Overskrida derma djuphetsgrans vid tjock papp Or forfaringssattet utveeklat darhan, att, innan pappen inkommer mellan det fOrsta bighjulsparet, pappen formas till en bukt aft ay styrhjulet 34a etc. yid mellanpartiet Indian bredvid varandra liggande bighjulspar A och B etc. Harigenom astadkomInes ett materialoyerskott mellan namnda bighjulspar, vilket. materialtiverskott kommer iitgangsmaterialet for bigen till godo, sa att materialanstrangningen med hansyn till tanjbarheten minskas. Utbuktningen Sn f Or det forsta bighjulsparet 1, 2 halles med fordel sa stor, att en mindre utbuktning 5b kvarstar for pappens genomvalsning genom det efterfoljande bighjulsparet 3, 4, dar bigen fullbordas under samma betingelser som vid Mrsta bighjulsparet. I nano. fall Or det vid forfaringssattet med utbuktade pappmellanpartier mojligt, att astadkomma bigen fullt far-dig Oven med endast ett bighjulspar 1, 2. However, this procedure is only possible at not too great a depth. In order to exceed this depth limit in the case of thick cardboard, the procedure has been developed so that, before the paperboard enters between the first pair of spare wheels, the paperboard is formed into a bend by the guide wheel 34a, etc., in the intermediate portion of Indian adjacent spare wheel pairs A and B, etc. material excess between said pair of spare wheels, which. material excess benefits the starting material for the bee, so that the material effort with regard to the extensibility is reduced. The bulge Sn f Or the first pair of wheels 1, 2 is advantageously kept so large that a smaller bulge 5b remains for the cardboard rolling through the subsequent pair of wheels 3, 4, where the blade is completed under the same conditions as in the first pair of wheels. I nano. case Is it possible in the procedure with bulged cardboard intermediate portions to achieve the big fully finished oven with only one pair of spare wheels 1, 2.
