Description

Uppfinnare: K Giihne Uppfinningen avser en anordning for hopvikning av den smala, oppna huvudanden av cigarrettpaket och liknande i cigarrettf8rpackningsmaskiner efter langdvikningsforloppet i en vikningskammare, i vilken cigarrettfOrpackningarna transporteras kontinuerligt i riktning mot en stapel och vilken är forsedd med rorliga vikningsanordningar. Inventor: K Giihne The invention relates to a device for folding the narrow, open main end of cigarette packs and the like in cigarette packaging machines after the long folding process in a folding chamber, in which the cigarette packs are transported continuously in the direction of a stack and which are provided with movable folding devices.

Anordningar aro kanda, med vilka den vid cigarrettpaketens smala sida annu oppna huvudanden hopvikes medelst i roterande skivor vridbart och excentriskt lagrade fingrar. Vid dessa i cirkelformiga rOrelser f8rsatta fingrar transporteras cigarrettpaketen samtidigt vi-dare i horisontellt lage (tyska patentet 417 770). Harvid erhalles emellertid till foljd av den stationara widpunkten och tangentiella Direlsen av fingret ojamna vikningar, eftersom de yttre kanterna av det roterande inslagningsfingret stravar att deformera det fardigvikta omslaget vid vidaretransporten. Devices are known in which the main end, which is still open at the narrow side of the cigarette package, is folded together by means of rotatably and eccentrically mounted fingers in rotating discs. At these fingers placed in circular motions, the cigarette packets are simultaneously transported further in a horizontal position (German patent 417 770). In this case, however, uneven folds are obtained due to the stationary widening point and the tangential direction of the finger, since the outer edges of the rotating wrapping finger tend to deform the finished folded cover during further transport.

Vidare aro anordningar kdnda, vid vilka de smala andytorna av cigarrettpaketen hopvikas medelst av excentriska vevmekanismer i rorelse forsatta gripare. I anslutning till denna hopvikning rora sig griparna med okad hastighet i riktning frdn cigarrettpaketen och dessa transporteras vidare av en transportkedj as medbringare till ett upptagningsmagasin (tyska patentet 442 638). Furthermore, devices are known in which the narrow end surfaces of the cigarette packets are folded together by means of eccentric crank mechanisms in moving grippers. In connection with this folding, the grippers move at an increased speed in the direction of the cigarette packets and these are further transported by a carrier of a transport chain to a pick-up magazine (German patent 442 638).

Dessutom aro anordningar kanda, med vilka tillslutningen av de smala sidorna sker medelst mot varandra rorliga hopvikningsdornar. Harvid rOra sig dessa dornar diagonalt i transportriktningen, och efter hopvikningen av de smala sidorna avlagsnas hopvikningsdornarna samtidigt och parallellt frail de hopvikta cigarrettpaketen (tyska patentet 879 670). In addition, there are devices with which the closing of the narrow sides takes place by means of mutually movable folding mandrels. In this case, these mandrels move diagonally in the direction of transport, and after the folding of the narrow sides, the folding mandrels are deposited simultaneously and in parallel from the folded cigarette packets (German patent 879 670).

De ovan beskrivna anordningarna aro Mrsedda for hopvikning av i forvag iordninggj orda cigarrettpaket med t. ex. en cellof an- Dupl. kl. 54 a: 4/03; 81 a: 7/01 folie eller liknande som yttre omslag och darvid i synnerhet aven som transportanordningar. Till folj d av anordnandet av roterande vev- och kurvmekanismer kunna med de parallellt i forhallande till varandra verkande griparna resp. hopvikningsdornarna vikningarna vid cigarrettpaketens smala sidor icke goras jamna, eftersom mekanismernas transmissionsfOrhallanden genom desammas konstruktiva anordning och det stora antalet ledstallen leda till oj dmnheter i vikningsforlopp et. The devices described above are intended for the folding of pre-prepared cigarette packets with e.g. and cellof an- Dupl. at 54 a: 4/03; 81 a: 7/01 foil or similar as outer cover and in particular also as transport devices. As a result of the arrangement of rotating crank and curve mechanisms, the grippers resp. the folding mandrels the folds at the narrow sides of the cigarette packets are not made even, since the transmission conditions of the mechanisms through their constructive arrangement and the large number of guide numbers lead to differences in the folding process.

Hopvikningen av cigarrettpaketens smala sidor sker som bekant awn med anordningar, vilkas vikningsklaffar medelst bultar arc fasta vid kugghjul, som ingripa i som slider utformade kuggstanger. Kuggstangerna aro vid dnden forsedda med rullar, som rora sig i slutna kurvbanor. Vikningsklaffarna svangas vid vikningsforloppet 900 och tillsluta darigenom de smala andsidorna av cigarrettpaketen och i ansIntning till detta arbetsfOrlopp bortdragas vikningsklaffarna parallellt i forhdllande till varandra frail cigarrettpaketen. Speciellt anordnade anslag vid kuggstangerna hindra en ytterligare svangning av viknings-, klaffarna (tyska patentet 934 150). The narrowing of the narrow sides of the cigarette packs takes place, as is well known, with devices, the folding flaps of which are fastened to gears by means of arc bolts, which engage in slider-shaped rack rods. The racks are at the end provided with rollers, which move in closed curve paths. The folding flaps are pivoted at the folding process 900 and thereby close the narrow sides of the cigarette packets, and in connection with this work process the folding flaps are pulled away in parallel in relation to each other from the cigarette packs. Specially arranged stops at the racks prevent a further oscillation of the folding flaps (German patent 934 150).

Anordnandet av kugghjul och kuggstanger, som atfora en konstant, fram och tillbaka gaende r8relse, leder till en snabb forslitning av kugghjulen och kuggstangerna och salunda till en icke noggrann styrning av desamma. Till foljd av de harda anslagen vid andring av vikningsklaffarnas rorelseriktning samt den icke noggranna styrningen ay kugghjulen och kuggstangssliderna uppsta ojamnheter i parallelliteten och darigenom ojamnt skarpa kanter vid hopvikningen av den smala huvudanden av cigarrettpaketen. The arrangement of gears and racks, which perform a constant, reciprocating motion, leads to a rapid wear of the gears and racks and thus to an inaccurate control of the same. As a result of the hard stops when changing the direction of movement of the folding flaps and the inaccurate control of the gears and rack sheaths, irregularities arise in parallelism and thereby unevenly sharp edges when folding the narrow head end of the cigarette packets.

For overvinnande av dessa nackdelar kannetecknas anordningen enligt uppfinningen darigenom, att var och en av vikningsanord- 9— — ningarna är svangbart anordnad pa ena armens ytterande av pa hada sidor om vikningSkammaren anbragta ledhavstanger och att vikningsanordningarnas motsatta ande och ledhavstangernas andra arm am forsedda med rullar, vilka aro anordnade att samverka med stationara kurvor for genomforande av vikningsfOrloppet. Harvid Ican den vikningsanordningarna uppbarande anden av ledhavstangen vara forsedd med anslag fOr begransning av vikningsanordningarnas rorelse. Etter genomfOrd hopvikning av havudanden itterforas vikningsanordningarna parallellt fran eiganettpaketen. ROrelsen av vikningsanordningarna och ledhavstangerna med de mot de stationara kurvorna anliggande rullarna sker medelst vid vikningsanordningen ()eh ledhavstangerna anordnade draggildrar. To overcome these drawbacks, the device according to the invention can be characterized in that each of the folding devices is pivotally arranged on the outer edge of one arm by two sea rods arranged on either side of the folding chamber and that the opposite spirit of the folding devices and the other arm of the led rod rods , which are arranged to cooperate with stationary curves for carrying out the folding process. In this case, the spirit of the articulated rod carrying the folding devices can be provided with appropriations for limiting the movement of the folding devices. After the sea duck has been folded, the folding devices are returned in parallel from the proprietary net packages. The movement of the folding devices and the articulated rods with the rollers abutting against the stationary curves takes place by means of tension traps arranged at the folding device () and the articulated rods.
