Abstract

The present invention relates to a method of and means for joining support cores of cardboard or the like. The invention is characterized in that a sleeve length intended to be cut into a number of cores is cut so that only a short length, possibly only a core remnant is left. Adhesive (4) is then applied on the end surface located perpendicular to the axis of the core, after which the leading end surface of a new sleeve length running perpendicularly to the longitudinal axis and substantially aligned with the first end surface, is pressed against the rear end (3) and splicing is achieved.

Description

502 Û67 å. längd, gáende vinkelrätt mot längdaxeln och i huvudsak kongruent med den förstnämnda ändytan, pressas mot den bakre ändytan och skarvning erhálles. En dylik skarvning kan ske mot en resthylsa eller mot en större längd, i extremfallet mot en hel, föregående hylslängd. Detta ger mycket starka hylsor även vid skarvarna, och i huvudsak inget skrot erhàl- les. Skulle en ändyta ha skadad form eller avvika från ett plan, vinkelrätt mot hylsans längdaxel, kan man lätt kapa en tunn skiva för att få rätt ändyta, och en dylik skiva är obetydlig i förhållande till ovannämnda resthylsor, alltsà endast ett obetydligt skrotproblem. Uppfinningen innefattar även en anordning för utförande av detta sätt. 502 Û67 å. Length, going perpendicular to the longitudinal axis and substantially congruent with the first-mentioned end surface, pressed against the rear end surface and splicing is obtained. Such a splicing can take place against a residual sleeve or against a larger length, in the extreme case against an entire, previous sleeve length. This gives very strong sleeves even at the joints, and essentially no scrap is obtained. Should an end face have a damaged shape or deviate from a plane, perpendicular to the longitudinal axis of the sleeve, one can easily cut a thin disc to get the right end face, and such a disc is insignificant in relation to the above-mentioned residual sleeves, i.e. only an insignificant scrap problem. The invention also comprises a device for carrying out this method.

Ritningar: Uppfinningen är närmare exemplifierad i bifogade figurer, av vilka figur l visar en anordning enligt uppfinningen och sät- tet att arbeta, figur 2 visar en olämplig skarv enligt tidi- gare känd teknik och figur 3 en skarv, erhàllen vid uppfinningen.Drawings: The invention is further exemplified in the accompanying figures, of which figure 1 shows a device according to the invention and the method of working, figure 2 shows an unsuitable joint according to prior art and figure 3 a joint obtained by the invention.

Utföringsexempel: Anordningen enligt uppfinningen visas i figur 1. 1 är ett magasin för enstycksmatare för hylsor med ràlängd , ovan och i patentkraven kallade hylslängder, avsedda att kapas till hylsor. 2 är ett maskinstativ och 3 är en inmatningssida med en pusher. 4 är en limningsstation och 5 en kapningsstation. 6 är en drivanordning med en del 6.1 vid pàföringssidan och en del 6.2 vid utmatningssidan. Dessa, bl.a. vid resthylsan, är avsedda att rotera resthylsa resp. hylslängd, och denna 502 067 3 kan bortkopplas, exempelvis vid sitt drivorgan. 7 är utgàngssidan med linjärt anhåll och kontinuerlig mätning, exempelvis datoriserad. 8 är en utmatare med magasin för färdigkapade hylsor.Exemplary embodiment: The device according to the invention is shown in figure 1. 1 is a magazine for one-piece feeders for sleeves with raw length, above and in the claims called sleeve lengths, intended to be cut into sleeves. 2 is a machine stand and 3 is an input side with a pusher. 4 is a gluing station and 5 a cutting station. 6 is a drive device with a part 6.1 on the application side and a part 6.2 on the discharge side. These, i.a. at the residual sleeve, are intended to rotate the residual sleeve resp. sleeve length, and this 502 067 3 can be disconnected, for example at its drive means. 7 is the output side with linear stop and continuous measurement, for example computerized. 8 is a dispenser with magazine for pre-cut sleeves.

Sättet enligt uppfinningen startas genom att man på ingångssidan ifyller en hylslängd. Pushern 3 står här i sitt bakre läge. Limningsstationen 4 är förvärmd till rätt temperatur. Ett ingående munstycke står i sitt bakre läge.The method according to the invention is started by filling in a sleeve length on the entrance side. The pusher 3 is here in its rear position. The gluing station 4 is preheated to the correct temperature. An inlet nozzle is in its rear position.

Kapstationens klingarm står i sitt övre läge, liksom de övre anhållen (6.l och 6.2). Utgångssidans linjära anhåll står inställt på det mått, som överensstämmer med önskad hylslängd efter kapning. Utgángssidans 7 utmatare står i sitt nedre läge. Ett styrsystem kan ha försetts med uppgifter om kaplängder.The blade arm of the cutting station is in its upper position, as are the upper stops (6.1 and 6.2). The linear stop of the output side is set to the dimension that corresponds to the desired sleeve length after cutting. The output side of the output side 7 is in its lower position. A control system may have been provided with information on cutting lengths.

Sedan maskinoperatören tryckt på start ilägges en hylslängd i inmataren i maskinens centrumlinje framför pushern 3. Denna skjuter därefter hylslängden fram mot ut- gàngssidans 7 anhàll, och hylslängden är nu fixerad mellan de bägge anhållen (6.l och 6.2). Det övre anhállet (6.l) går ned och rotationen av hylsan startar. Kapstationen 5 gör ett helt arbetsslag, vilket innebär ansättning mot hylslängdens periferi, rotation av hylsan ett varv samt återgång till viloläge. En kapning har nu fullbordats, och den färdigkapade hylsan placeras i sitt magasin 8.After the machine operator has pressed start, a sleeve length is inserted in the feeder in the center line of the machine in front of the pusher 3. This then pushes the sleeve length towards the stop side 7 stop, and the sleeve length is now fixed between the two stops (6.1 and 6.2). The upper stop (6.l) goes down and the rotation of the sleeve starts. The cutting station 5 performs a complete work stroke, which means application to the periphery of the sleeve length, rotation of the sleeve one turn and return to rest position. A cut has now been completed, and the pre-cut sleeve is placed in its magazine 8.

Denna procedur upprepas till dess den främre hylslängden färdigkapats och en resthylsa återstår. Vid detta mått förflyttar pushern 3 denna hylsa till ett beredskapsläge i 502 067 1/ limningsstationen 4, backar till sitt hemmaläge och en ny hylslängd ilägges i enstycksmataren. Den nya hylslängden skjuts nu fram till limningsstationen 4, övre anhállet (6.2) går ner på resthylsans periferi och startar rotationen av resthylsan, samtidigt som limstycket gär fram till sin arbetsposition. Under rotation páföres nu limmet ett varv pà resthylsans bakre ändyta, limstycket backar, varefter ingàngssidans pusher 3 sammanför de i huvudsak kongruenta ändytorna och sätter dessa under press, lämpligen i högst 10 sek.This procedure is repeated until the front sleeve length is completed and a residual sleeve remains. To this extent, the pusher 3 moves this sleeve to a standby position in the gluing station 4, backs to its home position and a new sleeve length is inserted in the one-piece feeder. The new sleeve length is now pushed forward to the gluing station 4, the upper stop (6.2) goes down on the periphery of the residual sleeve and starts the rotation of the residual sleeve, at the same time as the glue piece reaches its working position. During rotation, the adhesive is now applied one turn to the rear end surface of the residual sleeve, the adhesive piece backs, after which the entrance side pusher 3 joins the substantially congruent end surfaces and puts them under pressure, preferably for a maximum of 10 seconds.

Efter detta kan de sedvanliga kapningsoperationerna upprepas, och starka stödhylsor erhållas även vid skarvställena.After this, the usual cutting operations can be repeated, and strong support sleeves are also obtained at the splicing points.

För skarvning av hylsändytorna användes smältlim, där parametrarna för limaggregatet 4 för temperatur och mängd kan justeras för optimal styrka och fyllnadsgrad. Limmet pàlägges med ett och samma munstycke för samma hylsdimensioner då periferihastighet och godstjocklek i huvudsak stämmer. Genom att materialet i hylsorna är papp eller liknande material, alltsa ett antal ovanpà varandra liggande lager, så absor- beras limmet snabbt i ändytorna och fäster snabbt vid sam- mantryckningen. Man erhåller stark skarv även med relativt liten limmängd.For splicing the sleeve end surfaces, hot melt adhesive is used, where the parameters of the adhesive assembly 4 for temperature and quantity can be adjusted for optimal strength and degree of filling. The adhesive is applied with one and the same nozzle for the same sleeve dimensions as peripheral speed and wall thickness are essentially the same. Because the material in the sleeves is cardboard or similar material, ie a number of superimposed layers, the glue is quickly absorbed in the end surfaces and adheres quickly to the compression. You get a strong joint even with a relatively small amount of glue.

En skarv, erhállen vid tidigar känd teknik, visas i figur 2. I figur 3 visas en skarv, erhállen medelst sättet enligt uppfinningen. Den sistnämnda har en styrka, ungefär motsvar- ande en hylsa kapad vid sidan om skarvarna.A joint obtained in the prior art is shown in Figure 2. Figure 3 shows a joint obtained by the method according to the invention. The latter has a strength, approximately corresponding to a sleeve cut at the side of the joints.
