Fremgangsmåte og apparat til embåliering av ringformede gjenstander, særlig ledningskveiler.. Method and apparatus for wrapping ring-shaped objects, in particular wire coils.
Den foreliggende oppfinnelse angår embåliering av ringformede gjenstander, spesielt ledningskveiler. The present invention relates to the wrapping of ring-shaped objects, especially wire coils.
Ledningskveiler og andre ringformede gjenstander som a<y >forskjellige grunner bor emballeres, blir vanligvis omviklet med en strimmel av emballasje-materiale, f.eks. et krepp-papirbånd. Derved fås der en god emballasje som sitter stramt rundt legemet og i til-felle av ledningskveiler,. som består av flere vindinger, holder disse sikkert sammen til en fast ring. Samtidig blir legemets ring-form bibeholdt, noe som er praktisk for håndtering av de emballerte gjenstander. Imidlertid krever en slik omvikling, hvor båndet må fores gjennom ringåpningeh, relativt kostbart og komplisert maskineri. Wire coils and other ring-shaped objects that need to be packaged for various reasons are usually wrapped with a strip of packaging material, e.g. a crepe paper band. This results in good packaging that fits tightly around the body and, in the case of cable coils. which consists of several windings, these securely hold together to form a fixed ring. At the same time, the body's ring shape is retained, which is practical for handling the packaged items. However, such wrapping, where the tape must be fed through ring openings, requires relatively expensive and complicated machinery.
Der har også fremkommet forslag om å emballere ringformede gjenstander i et emballasjeark av en lengde omtrent svarende til legemets omkrets og en bredde omtrent svarende til omkretsen av tverrsnittet. Et slikt ark legges med sin langsgående midtlinje langs legemets ytre omkrets, og de to kanter av arket brettes inn over legemet og forenes ved dettes indre omkrets. Heller ikke en slik om-bretting av emballasjearket er særlig enkel å utfore•• Hertil kommer at endene av emballasjearket må" forenes på tvers av ringen for at emballasjen skal bli tett. There have also been proposals to package ring-shaped objects in a packaging sheet of a length approximately equal to the circumference of the body and a width approximately equal to the circumference of the cross-section. Such a sheet is placed with its longitudinal center line along the outer circumference of the body, and the two edges of the sheet are folded over the body and joined at its inner circumference. Nor is such a refolding of the packaging sheet particularly easy to carry out•• In addition, the ends of the packaging sheet must be joined across the ring in order for the packaging to be tight.
Videre er det kjent å emballere ledningskveiler i vanlige plastposer som forsegles. Ved en slik emballasje beholdes imidlertid ikke ringformen, noe som er en ulempe. Posene kan heller ikke holde sammen de enkelte vindinger av ledningskveilen, som derfor for den Furthermore, it is known to package wire coils in ordinary plastic bags which are sealed. With such packaging, however, the ring shape is not retained, which is a disadvantage. The bags also cannot hold together the individual windings of the cable coil, which is therefore the case for it
legges inn i plastposen må bensles på flere steder. placed in the plastic bag must be sealed in several places.
Endelig skal det nevnes at det er kjent å emballere kule-og rullelagre i to skikt av termoplast som etter tur vakuumformes delvis rundt lageret fra hver sin side av dette. Heller ikke ved en slik emballasje beholdes ringformen. Finally, it should be mentioned that it is known to package ball and roller bearings in two layers of thermoplastic which in turn are partially vacuum formed around the bearing from each side of it. Even with such packaging, the ring shape is not retained.
Den foreliggende oppfinnelse tar i forste rekke sikte på å skaffe en enkel og lettvint fremgangsmåte til embåliering av ringformede gjenstander, særlig ledningskveiler, under bibehold av ringformen. The present invention primarily aims to provide a simple and easy method for embalming ring-shaped objects, in particular wire coils, while maintaining the ring shape.
Fremgangsmåten ifolge oppfinnelsen har det til felles med enkelte av de foran nevnte, kjente fremgangsmåter at gjenstanden anbringes mellom to strekkbare skikt av sveisbart materiale, men ifolge oppfinnelsen blir skiktene deretter sveiset til hinannen langs den The method according to the invention has in common with some of the aforementioned known methods that the object is placed between two stretchable layers of weldable material, but according to the invention the layers are then welded to each other along the
utvendige og den innvendige kontur av den ringformede gjenstand og kappet i' eller ved sveiselinjene. Sveisingen og kappingen kan fortrinnsvis som kjent finne sted i samme operasjon, idet sveisebakkene samtidig deler materialet i sveisesommen. En slik fremgangsmåte er uhyre enkel å utfore og krever ikke annet utstyr enn passende, ringformede sveisebakker som er bevegelige i forhold til et underlag for den mellom de to skikt innlagte gjenstand. Emballasjematerialet kan fortrinnsvis utgjores av sveisbar plastfolie. De to folieskikt som gjenstanden legges inn mellom, kan enten være separate skikt eller de kan henge sammen- langs den ene kant, idet der f.eks. benyttes en foliebane som brettes om en midtlinje. . En emballasje som sitter strammere rundt gjenstanden,, og som derfor har bedre bruksegenskaper, kan fås ved at der som i og for external and the internal contour of the annular object and cut in or at the weld lines. As is known, the welding and the cutting can preferably take place in the same operation, as the welding trays simultaneously divide the material in the weld seam. Such a method is extremely simple to carry out and requires no other equipment than suitable, ring-shaped welding trays which are movable in relation to a base for the object inserted between the two layers. The packaging material can preferably be made of weldable plastic foil. The two layers of foil between which the object is placed can either be separate layers or they can hang together along one edge, as there e.g. a foil web is used which is folded around a center line. . A packaging that fits tighter around the object, and which therefore has better usability, can be obtained by where as in and for
seg kjent anvendes et emballasjemateriale som krymper ved varmepåvirkning, idet emballasjen etter forseglingen utsettes for varme for å krympe materialet og stramme emballasjen omkring gjenstanden. is known to use a packaging material that shrinks when exposed to heat, as the packaging is exposed to heat after sealing to shrink the material and tighten the packaging around the object.
Oppfinnelsen skaffer også et apparat til utforelse av en fremgangsmåte som angitt. Apparatet omfatter et ovre og et nedre par av konsentriske ringformede sveisebakker og et mellom sveisebakkene i det nedre par anordnet ringformet underlag for gjenstanden som skal emballeres, idet sveisebakkeparene og underlaget ér bevegelige i forhold til hverandre. The invention also provides an apparatus for carrying out a method as indicated. The apparatus comprises an upper and a lower pair of concentric ring-shaped welding trays and a ring-shaped substrate arranged between the welding trays in the lower pair for the object to be packaged, the pairs of welding trays and the substrate being movable in relation to each other.
Der foreligger naturligvis en rekke muligheter for den innbyrdes bevegelse av sveisebakkene og underlaget. Det foretrekkes å anordne sveisésommene såvidt mulig i legemets midtplan, og ved stillestående underlag vil sveisebakkene kunne være bevegelige for å motes omtrent i dette midtplan. Det vil imidlertid forstås at det ene bakkepar kan være stasjonært, og at underlaget for gjenstanden istedet kan utfores bevegelig. Et av bakkeparene kan være oppvarmet, mens det annet, kan tjene bare som motholdsbakker. Hvis det er det nedre bakkepar som utgjor motholdsbakkene, kan dette befinne seg over nivået for underlaget ved ilegning av gjenstanden, og motholdsbakkene tjener da som en foring for gjenstanden for å sikre at denne blir sentrert i forhold til bakkene. Underlaget kan være stasjonært, men kan eventuelt også utfores slik at det kan heves til nivået for motholdsbakkene for på denne måte å lette uttagning av den ferdig emballerte gjenstand, Naturally, there are a number of possibilities for the mutual movement of the welding trays and the substrate. It is preferred to arrange the welding seams as far as possible in the mid-plane of the body, and in the case of a stationary surface, the welding trays will be able to move to align approximately in this mid-plane. However, it will be understood that one ground pair can be stationary, and that the base for the object can instead be made movable. One of the hill pairs can be heated, while the other can only serve as counter-hold hills. If it is the lower pair of slopes that make up the counter-support slopes, this can be above the level of the substrate when the object is laid, and the counter-support slopes then serve as a liner for the object to ensure that it is centered in relation to the slopes. The base can be stationary, but can optionally also be lined so that it can be raised to the level of the counter-holding trays in order in this way to facilitate removal of the finished packaged item,
I en foretrukken utforelsesform av apparatet er de oppvarmede sveisebakker anordnet stasjonært, mens motholdsbakkene og underlaget for gjenstanden er bevegelige mot de oppvarmede bakker. In a preferred embodiment of the apparatus, the heated welding trays are arranged stationary, while the counter-holding trays and the base for the object are movable towards the heated trays.
Oppfinnelsen vil nå bli nærmere beskrevet under henvisning til tegningen, som sterkt skjematisk illustrerer en fremgangsmåte ifolge oppfinnelsen. Fig. ler et sterkt skjematisk vertikalsnitt som viser hvorledes den ringformede gjenstand og de to emballasjeskikt kan skyves frem mellom de to sveisebakkepar.
