Den foreliggende opfindelse angår et apparat til isætning af tætningslister i en not på en rektangulær dør eller vinduesramme og af den i indledningen til krav 1 angivne art.The present invention relates to an apparatus for inserting sealing strips into a groove on a rectangular door or window frame and of the kind specified in the preamble of claim 1.

5 Almindeligvis anbringes tætningslister i de noter, som er udfræset eller ekstruderet i de profilstave, som vindueseller dørrammer er fremstillet af. Et kendt apparat til formålet er beskrevet i USA-patentskrift nr. 3,335,487. Ved indsætning af tætningslisten i profilstaven inden samlingen af 10 rammen lettes en eventuel smigskæring, idet tætningsliste og profilstav eventuelt kan afskæres i en enkelt proces. I dette tilfælde trækkes tætningslisten ind i en profilnot fra enden af profilstaven, men fra beskrivelsen til britisk patent nr. 1.088.241 kendes et apparat til synkron fremføring af profil-15 staven og en tætningsliste gennem en isætningsindretning, der presser tætningslisten ind i en not i staven. En ulempe ved de kendte arrangementer er, at de ikke er egnet til isætning af en tætningsliste, der uden at blive overskåret føres rundt omkring en vinduesrammes hjørner. Ved at føre tætningslisten 20 rundt om hjørnene på vinduesrammen reduceres risikoen for at tætningslisten falder ud af noten, og der elimineres en utæthed ved hjørnet af rammen.5 Generally, sealing strips are placed in the grooves milled or extruded into the profile bars from which window or door frames are made. A known apparatus for the purpose is described in U.S. Patent No. 3,335,487. Insertion of the sealing strip in the profile bar before the assembly of the 10 frame facilitates a flatter cutting, as the sealing strip and profile rod can be cut off in a single process. In this case, the sealing strip is drawn into a profile groove from the end of the profile rod, but from the specification of British Patent No. 1,088,241, an apparatus for synchronously advancing the profile rod and a sealing strip is known through an insertion device which presses the sealing strip into a groove. in the wand. A disadvantage of the known arrangements is that they are not suitable for inserting a sealing strip which is carried around the corners of a window frame without being cut. Passing the sealing strip 20 around the corners of the window frame reduces the risk of the sealing strip falling out of the groove and eliminating a leak at the corner of the frame.

Formålet med den foreliggende opfindelse er derfor at tilvejebringe et apparat, med hvilket det er muligt at isætte 25 en tætningsliste uden at overskære denne i en rundtgående not på en vindues- eller dørramme, idet der skal være mulighed for at føre tætningslisten rundt om rammens hjørner.The object of the present invention is therefore to provide an apparatus with which it is possible to insert a sealing strip without cutting it into a circular groove on a window or door frame, the possibility of passing the sealing strip around the corners of the frame. .

Denne opgave løses ved, at apparatet ifølge opfindelsen er ejendommeligt ved det i den kendetegnende del af krav 30 1 angivne.This problem is solved by the fact that the apparatus according to the invention is peculiar to that of the characterizing part of claim 30 1.

Ved at opspænde rammen på en sådan måde, at den kan bevæge sig i to retninger og tillige rotere, er det muligt med en stationær isætningsindretning at bevæge rammen således, at listen kan sættes ind i den rundtgående not, idet 35 rammen skiftevis bringes til at udføre en translatorisk bevægelse med en sidekant langs isætningsindretningen og en roterende bevægelse med centrum ved det hjørne, som befinder sig ud for isætningsmekanismen.By clamping the frame in such a way that it can move in two directions and also rotate, it is possible with a stationary insertion device to move the frame so that the frame can be inserted into the circumferential groove, causing the frame to alternate perform a translational movement with a side edge along the insertion device and a rotary movement with the center at the corner which is adjacent to the insertion mechanism.

Af hensyn til tilpasningen til rammer af forskellig størrelse og til en enkel styring af bevægelsen, er det hensigtsmæssigt, at aksen, om hvilken opspændingsindretningen roterer, tilnærmelsesvis forløber gennem skæringspunktet for 5 den opspændte rammes diagonaler.For the sake of adaptation to frames of different sizes and to a simple control of movement, it is desirable that the axis about which the clamping device rotates extend approximately through the intersection of the diagonals of the clamped frame.

En særlig egnet opspændingsmekanisme, som især er fordelagtig i forbindelse med en gennem diagonalernes skæringspunkt forløbende rotationsakse, er ifølge opfindelsen ejendommelig ved det i kravene 3, 4 og 5 angivne. En sådan op-10 spændingsmekanisme muliggør en hurtig tilpasning ikke alene til rammer af forskellig størrelse, men tillige til rammer med forskelligt forhold mellem de to sæt parallelle sider.A particularly suitable clamping mechanism, which is particularly advantageous in connection with a axis of rotation passing through the intersection of the diagonals, is according to the invention characterized by the claims 3, 4 and 5. Such a tensioning mechanism enables a quick adaptation not only to frames of different sizes, but also to frames with different ratios between the two sets of parallel sides.

Ved at udforme apparatet ifølge opfindelsen som angivet i krav 6, opnås en særlig enkel styring af den roterende 15 bevægelse omkring hvert af rammens hjørner. Rullerne tjener dels til styring af opspændingsmekanismen under den transla-toriske bevægelse, idet to af rullerne herved er i kontakt med skinnen, dels til styring af rotationsbevægelsen, hvor den rulle, som befinder sig ud for isætningsindretningen, 20 fastlåses til skinnen og derved kommer til at tjene som omdrejningspunkt for den roterende bevægelse, når opspændingsmekanismen som helhed bevæges på langs i skinnens retning.By designing the apparatus according to the invention as claimed in claim 6, a particularly simple control of the rotating movement is obtained around each of the corners of the frame. The rollers serve partly to control the clamping mechanism during the translational movement, two of the rollers being in contact with the rail and partly to control the rotational movement, where the roller which is outside the insertion device 20 is locked to the rail and thereby arrives to serve as the focal point of the rotary motion as the clamping mechanism as a whole is moved longitudinally in the direction of the rail.

Ved en sådan bevægelse vil rammen så at sige blive kæntret omkring et af dens hjørner. Når rammen er blevet kæntret tre 25 gange, og alle fire sider af rammen har fået isat tætningslisten, er processen færdig. Rammen kan derefter køres langs skinnen ud til en af apparatets ender, hvorefter opspændingsmekanismen drives i modsat retning til udløsning af rammen, der kan løftes ud og en anden kan ilægges, hvorefter proces-30 sen kan gentages.In such a move, the frame will, so to speak, become chiseled around one of its corners. When the frame has been flattened three times and all four sides of the frame have been sealed, the process is complete. The frame can then be run along the rail to one of the ends of the apparatus, after which the clamping mechanism is driven in the opposite direction to release the frame which can be lifted out and another can be loaded, after which the process can be repeated.

I det følgende beskrives en på tegningen vist udførelsesform for apparatet ifølge opfindelsen. På tegningen viser:In the following, an embodiment of the apparatus according to the invention is shown in the drawing. In the drawing:

3 fatter en opspændingsmekanisme 1 for rammen. Opspændingsmekanismen har to hinanden krydsende føringsskinner 2,3, der tjener til styring og bevægelse af ialt fire gribebakker 4, der hver er udformet som en vinkelformet holder, der kan holde om 5 de to rammesider, som mødes i et hjørne af rammmen. Gribebak-kerne er udformet således, at de ikke dækker for den not, i hvilken tætningslisten skal indsættes. De to føringsskinner 2,3 krydser hinanden i et nav 5, der dels indeholder den til bevægelsen nødvendige drivmekanisme til gribebakkerne, dels 10 er således udformet, at vinkelstillingen mellem de to føringsskinner kan indstilles. Denne indstillingsmulighed er hensigtsmææsig, idet den muliggør en tilpasning af opspændingsmekanismen til rammer af forskellige dimensioner både i højde og i bredde. Selve tilspændingen sker ved forskydning 15 af gribebakkerne i retning mod navet langs føringsskinnerne 2.3. Bevægelsen kan etableres ved hjælp af skruespindler, som befinder sig indvendigt i de som et kasseformet profil med to modstående langsgående åbninger udformede føringsskinner. Skruespindlerne drives ved hjælp af et kronhjul, der er i 20 indgreb med et spidshjul på hver af spindlerne, og som derved driver de fire spindler synkront. Uanset hvilken størrelse rammen har, vil den derfor befinde sig med skæringspunktet for dens diagonaler ud for centrum af navet 5. Når vinklen mellem føringsskinnerne ændres, er det nødvendigt samtidig at 25 ændre indstillingen af gribebakkerne i forhold til føringsskinnerne. Gribebakkerne 4 er derfor drejelige omkring en akse, hvis forlængelse netop skærer vidusrammen der, hvor de to noter i rammens stave løber sammen ved rammens hjørner.3 includes a clamping mechanism 1 for the frame. The clamping mechanism has two intersecting guide rails 2,3 which serve to control and move a total of four gripping trays 4, each designed as an angular holder which can hold the two frame sides which meet at one corner of the frame. The gripping trays are designed so that they do not cover the groove into which the sealing strip is to be inserted. The two guide rails 2,3 intersect in a hub 5 which partly contains the drive mechanism necessary for the movement of the gripping trays and partly 10 is designed so that the angular position between the two guide rails can be adjusted. This adjustment option is appropriate in that it allows an adaptation of the clamping mechanism to frames of different dimensions both in height and in width. The actual tightening is done by displacing the gripping trays 15 towards the hub along the guide rails 2.3. The movement can be established by means of helical spindles located inside the guide rails formed as a box-shaped profile with two opposite longitudinal openings. The screw spindles are driven by means of a crown wheel which is in engagement with a spinning wheel on each of the spindles, thereby driving the four spindles synchronously. Therefore, regardless of the size of the frame, it will be at the point of intersection of its diagonals outside the center of the hub 5. When the angle between the guide rails is changed, it is necessary at the same time to change the setting of the gripping trays relative to the guide rails. The gripping trays 4 are therefore rotatable about an axis whose extension precisely intersects the vidus frame where the two notes in the frame's rods run together at the corners of the frame.

Opspændingsmekanismen er lejret på en slæde 6 omkring 30 en akse, der forløber vinkelret på planet for den opspændte ramme, og som går gennem skæringspunktet for føringsskinnerne 2.3. Slæden 6 kan hensigtsmæssigt bære drivmotoren for til-spændingsbevægelsen. Slæden er forskydelig i retning op og ned langs to tilnærmelsesvis lodrette skinner 7, der er for- 35 bundet til en stiv helhed ved hælp af to traverser 8. Ved enderne af de to skinner 7 er der glidestyr 9, der glider langs vandrette glideskinner 10 fastgjort til en med to vandrette bærevanger 11 forsynet bæreramme. På fig 1 ses kun en del af ----------- 4The clamping mechanism is mounted on a carriage 6 about 30 an axis extending perpendicular to the plane of the clamped frame and passing through the intersection of the guide rails 2.3. The carriage 6 may conveniently carry the drive motor for the tension movement. The carriage is slidable in the up and down direction along two approximately vertical rails 7 connected to a rigid unit by means of two traverses 8. At the ends of the two rails 7 there is sliding guide 9 sliding along horizontal sliding rails 10 attached to a carrier frame provided with two horizontal support arms 11. In Figure 1, only part of ----------- 4 is seen

skinnerne 10 og vangerne 11, idet de gavle eller søjler, som bærer vangerne 11, og som holder dem i fast indbyrdes afstand, er udeladt for at gøre andre detaljer tydeligere. Disse dele kan imidlertid udformes på helt traditionel måde.the rails 10 and the racks 11, the gables or columns supporting the rails 11 and holding them at a fixed distance from each other, are omitted to make other details clearer. However, these parts can be designed in a very traditional way.

5 Foran den nederste bærevange 11 løber der en skinne 12, hvis formål skal forklares nærmere i forbindelse med fig. 2.5 A rail 12 runs in front of the lower carrier 11, the purpose of which is explained in more detail in connection with FIG. 2nd

Fig. 2 viser apparatet ifølge fig. 1 set i et snit gennem stativet omfattende bærevangerne 11. På figuren er en mulig udformning for en gavl 13 til understøtning af vangerne 10 11 antydet. På figuren ses slæden 6, på hvilken opspændings mekanismen 1 med føringsskinnerne 2,3 er roterbart lejret. På fig. 2 er der antydet en i opspændingsmekanismen fastspændt vinduesramme 14. Foran vinduesrammen 14 er en stationær isætningsmekanisme 15 placeret. Isætningsmekanismen trækker tæt-15 ningslisten 16 fra en forrådsrulle. Mekanismer til isætning af profillister i noter er kendt, og den her anvendte mekanisme udgør derfor ikke en del af den beskrevne opfindelse.FIG. 2 shows the apparatus of FIG. 1 is a sectional view through the frame comprising the support vanes 11. In the figure, a possible design of a gable 13 for supporting the vanes 10 11 is indicated. The figure 6 shows the carriage 6 on which the clamping mechanism 1 with the guide rails 2,3 is rotatably mounted. In FIG. 2, there is indicated a window frame 14 clamped in the clamping mechanism. A stationary insertion mechanism 15 is located in front of the window frame 14. The insertion mechanism pulls the seal strip 16 from a supply roll. Mechanisms for inserting profiling lists into notes are known, and the mechanism used herein does not form part of the invention described.

For at mekanismen kan fungere, fordres et drev, som er synkroniseret med fremføringen af den ramme, hvori noten befin-20 der sig. Et sådant synkroniseret drev kan etableres på mange måder, som er beskrevet i den tekniske litteratur, f.eks. ved hjælp af kardanske aksler eller ved hjælp af elektriske eller elektroniske forbindelser.For the mechanism to work, a drive that is synchronized with the advance of the frame in which the groove is located is required. Such a synchronized drive can be established in many ways described in the technical literature, e.g. by means of cardan shafts or by means of electrical or electronic connections.

På den mod slæden 6 vendende side af opspændingsmeka-25 nismen er der ud for hver af gribebakkerne 4 og på den modsatte side af styreskinnerne 2,3 monteret en rulle 17. Rullen bevæges af tilspændingsmekanismen sammen med gribebakken 4 og rullens akse falder sammen med drejningsaksen for gribebakken, dvs. aksens forlængelse løber gennem mødestedet for no-30 terne.ved rammehjørnerne. Rullerne 17 er indrettet til at løbe på skinnen 12. Ved isætning af tætningslisten i en not fremføres opspændingsmekanismen langs skinnerne ved hjælp af en ikke vist drivmotor, som ved hjælp af f.eks. et kædetræk driver de lodrette skinner 7 langs skinnerne 10. Derved føres 35 rammen langs isætningsmekanismen med noten i korrekt afstand i forhold til denne uanset rammens størrelse, idet rullerne IT indgår i det system, som tilpasses efter rammens dimensio ner. Når det ved hjælp af en føler eller en fotocelle på 5On the side facing the carriage 6 of the clamping mechanism, a roller 17 is mounted next to each of the gripping trays 4 and on the opposite side of the guide rails 2,3. The roller is moved by the clamping mechanism with the gripping tray 4 and the axis of the roller coincides with the axis of rotation. for the grab tray, ie. the extension of the axis runs through the meeting point of the no-30s. at the corner of the frame. The rollers 17 are arranged to run on the rail 12. By inserting the sealing strip into a groove, the clamping mechanism is carried along the rails by means of a drive motor (not shown) which, e.g. a chain drive drives the vertical rails 7 along the rails 10. Thus, the frame is guided along the insertion mechanism with the groove at a proper distance from it regardless of the size of the frame, the rollers IT being part of the system which is adapted to the dimensions of the frame. When using a sensor or a photocell of 5

isætningsmekanismen konstateres, at der er blevet sat tætningsliste i hele længden af noten på den side af rammen, skal rammen drejes, således at man kan fortsætte isætningen på den tilstødende rammeside. Drejningen af rammen sker ved, 5 at rullen 17 ud for det hjørne på rammen, hvortil man er kommet med isætningen fastlåses til skinnen 12. Fastlåsningen kan ske ved hjælp af et pneumatisk bevæget lejehus 18, der af den neden for skinnen 12 placerede cylinder 19 presses ned over rullen 17. Herefter omstyres drevet for de lodrette 10 skinner 7, hvorved rammen 14 kæntrer omkring lejringen for den låste rulle 17. Når rammen er drejet 90°, vendes drevet på ny, og rammen kan nu fremføres til isætning af en yderligere længde af tætningslisten. Isætningsmekanismen kan være forsynet med en yderligere fotocelle, som registrerer, at det 15 næste hjørne nærmer sig og som udløser en kniv, som udskærer et hak i tætningslisten netop på det sted, som kommer til at svare til hjørnet på rammen. Endvidere kan isætningsmekanismen være forsynet med en kniv, der aktiveres på et passende tidspunkt til overskæring af tætningslisten ved dens samling.If the insertion mechanism is found to have a sealing strip inserted throughout the length of the groove on that side of the frame, the frame must be rotated so that the insertion can be continued on the adjacent frame side. The rotation of the frame is effected by locking the roller 17 out of the corner of the frame to which the insert has been fitted to the rail 12. The locking can be effected by means of a pneumatically movable bearing housing 18 which is placed by the cylinder 19 below the rail 12. pressed down over the roller 17. Then the drive for the vertical rails 7 is overthrown, whereby the frame 14 turns around the bearing of the locked roller 17. When the frame is turned 90 °, the drive is reversed again and the frame can now be advanced for insertion of a further length of the sealing strip. The insertion mechanism may be provided with an additional photocell which detects that the next corner is approaching and which releases a knife which cuts a notch in the sealing strip at the exact location corresponding to the corner of the frame. Furthermore, the insertion mechanism may be provided with a knife which is activated at an appropriate time for cutting the sealing strip at its assembly.

20 Hvis samlingen skal være placeret ved et hjørne, bør overskæringen ske i smig, medens overskæringen kan være vinkelret på listen, dersom samlingen placeres et sted mellem to af rammens hjørner.20 If the joint is to be placed at a corner, the cutting should be flattered, while the cutting may be perpendicular to the list if the joint is placed somewhere between two of the corners of the frame.

Det bemærkes, at der ikke er behov for et drev for den 25 lodrette bevægelse af slæden 6 langs skinerne 7. Fortrinsvis udbalanceres den største del af opspændingsmekanismens og slædens vægt ved hjælp af en kontravægt, en fjeder eller tilsvarende, således at den vægt, der overføres fra rullerne 17 til skinnen 12, ikke er meget større end vægten af rammen.It is noted that a drive is not required for the vertical movement of the carriage 6 along the rails 7. Preferably, most of the weight of the clamping mechanism and the carriage is balanced by a counterweight, a spring or the like, so that the transmitted from rollers 17 to rail 12 is not much greater than the weight of the frame.

30 Det er hensigtsmæssigt, at den motor 20, som driver tilspæn-dingen af gribebakkerne 4 ved rotation af det i navet 5 placerede kronhjul, frikobles fra dette så snart tilspændingen er foretaget. Derved kan opspændingsmekanismen rotere frit ved kæntringen af den opspændte ramme.It is convenient that the motor 20, which drives the tension of the gripping trays 4 by rotating the crown wheel located in the hub 5, is released from this as soon as the tightening is done. Thereby, the clamping mechanism can rotate freely upon the tensioning of the clamped frame.

35 Det skal bemærkes, at selv om en tilnærmelsesvis lod ret placering af rammen under isætningen i praksis vil vise sig mest formålstjenlig, kan man også benytte udformninger af apparatet, hvor rammen er placeret vandret eller næsten vand-35 It should be noted that although a practically shallow positioning of the frame during insertion will prove to be most useful in practice, designs of the apparatus where the frame is located horizontally or nearly water-wise can also be used.
