Abstract

Anordning för perforerande av papper som innefattar en glasskiva (6) och en cirkelformadkniv (5) som rullar över glasskivan under det att den pressas mot glasskivan. I glasskivan ärspår (7)anordnade i tvärled i förhållande till knivens rörelsebana och vid spåren skärs pappret inte av utan forbindningar uppstår. Device for perforating paper comprising a glass sheet (6) and a circular-shaped knife (5) which rolls over the glass sheet while being pressed against the glass sheet. In the glass plate grooves (7) are arranged transversely in relation to the path of movement of the knife and at the grooves the paper is not cut off but connections are made.

Description

20 25 30 534 855 spåren inte papperet helt av utan korta förbindningar mellan det tillskuma stycket papper (tork- eller tvättduk exempelvis) och den fortsatta pappersbanan kvarstår. När användaren skall använda den framställda fuktade tvättlappen eller en torr handduk kan de kvarstående förbindningarna lätt rivas av. 20 25 30 534 855 the tracks do not completely come off but short connections between the foamed piece of paper (cloth or washcloth for example) and the continued paper web remain. When the user is to use the prepared damp cloth or a dry towel, the remaining connections can be easily torn off.

Kniven dras fram och tillbaka av ena parten av en dubbel rem 14 som löper över kuggdrev 15 på bägge sidor om pappersbanan. Remmen 14 drivs av en motor 8. Lägesavkännare 9 och 10 stoppar den tvårgående rörelsen när perforeringen gjorts. Skärandet sker i omväxlande riktingar. Kniven är monterad mellan två plåtar 16 som täcker knivens sidor utom där denna skall rulla på glasskivan. Plåtarna är monterade på en fjäder 17 som är fäst i en löpare 18 vid vilken även remmen är fäst. Löparen är styrd i en styming som sträcker sig tvärs över pappersbanan..The knife is pulled back and forth by one part of a double belt 14 which runs over gears 15 on both sides of the paper web. The belt 14 is driven by a motor 8. Position sensors 9 and 10 stop the transverse movement when the perforation has been made. The cutting takes place in alternating directions. The knife is mounted between two plates 16 which cover the sides of the knife except where it is to roll on the glass plate. The plates are mounted on a spring 17 which is attached to a runner 18 to which the belt is also attached. The runner is guided in a steering that extends across the paper web ..

För anpassning till olika pappers användning och/eller papperskvalité kan antalet kvarlärnnade förbindningar ändras genom att man ändrar antalet spår eller bredden här-på.To adapt to different paper use and / or paper quality, the number of leftover connections can be changed by changing the number of grooves or the width here.

Detta kan antingen ske genom att byta glasskivor eller genom att förskjuta en glasskiva försedd med olika antal eller olika breda spår på olika ställen och som kan placeras mitt för knivbanan.This can be done either by changing glass sheets or by moving a glass sheet provided with different numbers or different wide grooves in different places and which can be placed in the middle of the knife path.

När perforeringen skett så matas pappersbanan fram cirka 6 cm så att den hamnar framför munstyckena avskärmande dessa. Denna extra frammatning minskar risken för att pappers- banan fastnar eftersom risken härför är störst i anslutning till avskärningsplatsen. Om av något skäl vätska stänkt på plåten framför munstyckena så torkas plåten torr och ren härigenom ytterligare minskande risken för att pappret skall häfta fast.When the perforation has taken place, the paper web is fed forward approximately 6 cm so that it ends up in front of the nozzles shielding them. This extra feed reduces the risk of the paper web getting stuck as the risk of this is greatest in connection with the cutting point. If for some reason liquid is splashed on the plate in front of the nozzles, the plate is dried dry and clean, thereby further reducing the risk of the paper sticking.

För att åstadkomma en bekymrnersfri och pappret väl utnyttjande automat är det känt att skarva veckat papper i det tillhörande magasinet. Skarvningen sker i princip genom ett sammanhäftande av ändpappren i veckade pappersstaplar med varandra Detta resulterar i ett dubbelt så tjockt ark med liminnehåll som kniven inte kan perforera. Dessa stycken får därför kasseras. Genom att låta skärskivan vara fjädrande förspänd mot glasskivan rullar skivan över skarven (om denna hamnar mitt för kniven). Om så önskas kan man anordna en avkånnare som känner av knivens rörelse när den råkar på en skarv så att drivningen kan mata fram pappret tillräckligt för att låta kniven göra ett nytt försök.In order to achieve a worry-free and paper-utilizing machine, it is known to splice pleated paper in the associated magazine. The splicing takes place in principle by adhering the end papers in folded paper stacks to each other. This results in a sheet twice as thick with glue content that the knife cannot perforate. These pieces may therefore be discarded. By leaving the cutting disc resiliently biased towards the glass disc, the disc rolls over the joint (if this ends up in the middle of the knife). If desired, a sensor can be provided which senses the movement of the knife when it hits a joint so that the drive can feed the paper sufficiently to allow the knife to make a new attempt.

För att göra omladdandet av en automat så lätt som möjligt kan med fördel en avkännare monteras som avkänner att magasinet börjar bli tomt och stoppar utrnatningen innan magasinet blir tomt så att man helt enkelt i vanlig ordning kan fylla på magasinet underifrån och limma ihop de mot varandra vända ändarken. Härigenom behöver man inte leda om pappersbanan varje gång pappret tar slut. 534 BBS Den rullande kniven har också visat sig ha fördelen att den inte fabricerar damm som kan sätta sig nmt munstyckena. vilket i sin tur skulle kunna leda till försämrad besprutning av pappret liksom risk för att munstyckena droppar vätska. För att ytterligare förbättra tilltörlitligheten bör även papperskvalitéer användas som dammar så lite som möjligt.In order to make the reloading of a vending machine as easy as possible, a sensor can advantageously be mounted which senses that the magazine is starting to become empty and stops the exhaust before the magazine becomes empty so that you can simply fill the magazine from below and glue them together turn the end sheets. This means that you do not have to redirect the paper path every time the paper runs out. 534 BBS The rolling knife has also been shown to have the advantage that it does not fabricate dust that can settle to the nozzles. which in turn could lead to impaired spraying of the paper as well as the risk of the nozzles dripping liquid. To further improve the reliability, paper grades should also be used that dust as little as possible.
