Description
509 692 2 ganet till en längd som åtminstone överensstämmer med längden hos den avskurna delen av filmen eller folien. 509 692 2 to a length which at least corresponds to the length of the cut part of the film or foil.
Uppfinningen beskrivs närmare nedan under hänvisning till bifogade ritning, på vilken fig 1 är en vy framifrån av en utföringsform av en anordning för frammatning av filmen, och fig 2 är en sidovy av samma utföringsform av anordningen.The invention is described in more detail below with reference to the accompanying drawing, in which Fig. 1 is a front view of an embodiment of a device for feeding the film, and Fig. 2 is a side view of the same embodiment of the device.
I det föredragna utföringsform, som visas på ritningen, ligger filmen på en rulle 9, som vilar mot en vals 10. Valsen 10 drivs av en kedja, så att matningen av plastfilmen regleras efter frammatningshastigheten och är synkron med frammatningen.In the preferred embodiment shown in the drawing, the film lies on a roller 9, which rests against a roller 10. The roller 10 is driven by a chain, so that the feed of the plastic film is regulated according to the feed rate and is synchronous with the feed rate.
Filmen l hålls mot en hal yta 2 medelst matningsskenor 3 i läget 3' nära de två hörnen hos filmen.The film 1 is held against a slippery surface 2 by means of feed rails 3 in the position 3 'near the two corners of the film.
Matningsskenan är anordnad att därefter dras utmed den hala ytan 2 medelst ändlösa, böjliga organ 5, såsom kedjor, och är inrättad att dra filmen med sig till änden av den hala ytan 2, där matningsskenan 3 lösgör sitt grepp om filmen och stannar.The feed rail is arranged to then be pulled along the slippery surface 2 by means of endless, flexible members 5, such as chains, and is arranged to pull the film with it to the end of the slippery surface 2, where the feed rail 3 loosens its grip on the film and stops.
Samtidigt griper ett nytt par matningsskenor 3 filmen i läget 3', varpå filmen skärs av skärmekanismen 4. Om filmen är en plastfilm består skärmekanismen 4 företrädesvis av en värmetràd, som är monterad på en rörlig mekanism. Efter det att filmen har skurits är det avskurna stycket icke längre fäst vid anordningen och kan falla ned på en kartong, som är placerad under anord- ningen.At the same time, a new pair of feed rails 3 grips the film in position 3 ', whereupon the film is cut by the cutting mechanism 4. If the film is a plastic film, the cutting mechanism 4 preferably consists of a heating wire mounted on a movable mechanism. After the film has been cut, the cut piece is no longer attached to the device and can fall onto a carton, which is placed under the device.
De friktionsbelagda matningsskenorna 3 griper tag i de främre hörnen av filmen genom att de trycker dem mot de hala ytorna 2, vilka sträcker sig utmed var sida av de spår, pä vilka filmen skall frammatas. Tack vare den stora skillnaden i frik- tion nællan filmen/den hala ytan och filmen/friktionsbelägg- ningen dras filmen tillsammans med matningsskenan 3 allteftersom matningsskenan rör sig utefter de hala ytorna 2. Matningsskenor- na 3 är monterade på ett ändlöst, böjligt organ 5, såsom en kedja, en rem etc. De hala ytorna 2 är stationära. 3 509 692 När matningsskenorna har dragit filmen till det önskade läget upphör trycket mellan matningsskenorna och den hala ytan genom att den hala ytan upphör eller genom att matningsskenorna lyfts upp från den hala ytan. Matningsskenan förlorar därigenom sitt grepp om filmen. Samtidigt griper en ny uppsättning av matningsskenor tag i filmen vid läget 3', och filmen skärs medelst skärorganet under det ställe, där den nya uppsättningen av matningsskenor har gripit tag i filmen. På detta sätt bildas ett filmstycke som icke längre är fäst vid matningsmekanismen samtidigt som matningsmekanismen är redo för en ny cykel.The friction-coated feed rails 3 grip the front corners of the film by pressing them against the slippery surfaces 2, which extend along each side of the grooves on which the film is to be fed. Due to the large difference in friction between the film / the slippery surface and the film / friction coating, the film is pulled together with the feed rail 3 as the feed rail moves along the slippery surfaces 2. The feed rails 3 are mounted on an endless, flexible member 5 , such as a chain, a strap, etc. The slippery surfaces 2 are stationary. When the feed rails have pulled the film to the desired position, the pressure between the feed rails and the slippery surface ceases by the slippery surface ceasing or by the feed rails being lifted from the slippery surface. The feed rail thereby loses its grip on the film. At the same time, a new set of feed rails grips the film at the position 3 ', and the film is cut by the cutting means below the place where the new set of feed rails has gripped the film. In this way a film piece is formed which is no longer attached to the feed mechanism at the same time as the feed mechanism is ready for a new cycle.
När filmstycket icke längre är fäst vid anordningen staplas ett antal varor ovanpå filmen, så att filmen dras ned i kartongen före varorna. Filmen kan slutligen vikas runt varorna, så att de innesluts i filmen.When the piece of film is no longer attached to the device, a number of goods are stacked on top of the film, so that the film is pulled down into the carton before the goods. The film can finally be folded around the goods, so that they are enclosed in the film.
Skärmekanismen måste anpassas till den särskilda film eller folie som utnyttjas. När en plastfilm utnyttjas föredrar man att utnyttja en värmetråd, som är monterad på en svängarm, vilken är anordnad att svänga mot filmen, när filmen skall skäras av.The screen mechanism must be adapted to the particular film or foil used. When a plastic film is used, it is preferred to use a heating wire, which is mounted on a pivot arm, which is arranged to pivot against the film, when the film is to be cut off.
Tryckluft kan om det är nödvändigt utnyttjas såsom en motverkande kraft.Compressed air can, if necessary, be used as a counteracting force.
