Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung bezieht sich auf einen Nahtbügelplatz für das Ausbügeln von Stoffnähten unter Dampfanwendung, bestehend aus einem Ständer mit Gebläse, einem daran befestigten absaugbaren Bügelholm, dessen Bügelauflage ein in seiner Erstreckung umlaufendes, in seiner Umlaufrichtung steuerbares Förderband ist, einem über dem Bügelholm ebenfalls am Ständer befestigten Oberholm, einem im Oberholm angeordneten zum Förderband hin absenkbaren Formpreßkörper mit einer beheizbaren an einen Dampferzeuger anschließbaren Dampfkammer, einer die Dampfkammer an ihrer Unterseite abschließenden Formpreßplatte mit Dampfaustrittsöffnungen, einer steuerbaren Stoffnaht-Einfädelvorrichtung am freien Ende des Oberholms sowie einem den Bügelholm über die Stoffnaht-Einfädelvorrichtung hinaus verlängernden Aufnahmeholm.The invention relates to a seam ironing place for ironing fabric seams using steam, consisting of a stand with a blower, an attached suction bar, the bracket support is a circumferential in its extent, controllable in its direction of rotation, one above the bar also on the stand attached upper spar, a molded body arranged in the upper spar, which can be lowered towards the conveyor belt, with a heatable steam chamber that can be connected to a steam generator, a shaped pressure plate that closes the steam chamber on its underside with steam outlet openings, a controllable fabric seam threading device at the free end of the upper spar, and a strap spar over the fabric seam. Threading device also extends the receiving spar.

STAND DER TECHNIKSTATE OF THE ART

Nahtbügelplätze dieser Art sind beispielsweise durch die Literaturstelle US-PS 3.107.447 bekannt. Sie haben die Aufgabe, die Zeit, die das Ausbügeln von Nähten, insbesondere bei der Herstellung von Kleidungsstücken in Verbindung mit Bügelarbeiten erfordern, wesentlichen zu reduzieren.Seaming places of this type are known, for example, from the literature reference US Pat. No. 3,107,447. Their job is to significantly reduce the time it takes to iron seams, especially when making garments in connection with ironing.

Wie die Praxis zeigt, ergeben sich bei hohen Anforderungen an ein einwandfreies und sauberes Ausbügeln solcher Stoffnähte außerordentliche Schwierigkeiten, diesen Vorgang zu automatisieren. Diese Schwierigkeiten rühren insbesondere daher, daß das zu bearbeitende Stoffmaterial hinsichtlich seiner Eigenschaften und seiner Beschaffenheit in außerordentlich weiten Grenzen unterschiedlich geartet ist und hierdurch bedingt bereits das einwandfreie Einziehen des Stoffes in seinem Nahtbereich zwischen den Bügelholm und den Oberholm je nach Stoffart und Stoffstärke mehr oder weniger gut, jedenfalls nicht in allen Fällen zufriedenstellend verläuft.As practice shows, with high demands on a perfect and clean ironing of such fabric seams there are extraordinary difficulties in automating this process. These difficulties are due in particular to the fact that the material to be processed is of extremely wide variety in terms of its properties and its nature and, as a result, the proper pulling in of the material in its seam region between the bow spar and the upper spar is more or less dependent on the type and thickness of the fabric well, at least not always satisfactorily.

Durch die Literaturstelle GB-PS 143.657 ist ebenfalls ein Nahtbügelplatz der vorbezeichneten Art bekannt, bei dem das zu bügelnde Stoffgut nicht auf einem Förderband zwischen die Holme eingefahren, sondern mit Hilfe einer längs den Holmen verschiebbaren und am Bügelholm befestigten Klemme, die das Stoffgut randseitig greift, eingezogen wird.From the literature reference GB-PS 143.657 a seam ironing place of the aforementioned type is also known, in which the material to be ironed is not moved in between the bars on a conveyor belt, but with the aid of a clamp which can be moved along the bars and fastened to the bar and which grips the fabric on the edge , is drawn in.

Abgesehen davon, daß eine solche Einziehvorrichtung nur relativ langsame Arbeitszykluszeiten zuläßt und darüber hinaus ein bearbeitetes Stoffteil praktisch von Hand wiederum vom Bügelholm abgezogen werden muß, ist damit ein einwandfreies Einziehen der Stoffteile nicht gewährleistet, weil sich der Stoff beim Einziehen auf dem Bügelholm sehr leicht nach der einen oder anderen Seite verschiebt und dann ein einwandfreies Ergebnis beim Ausbügeln der Naht nicht erreicht werden kann.Apart from the fact that such a pull-in device only allows relatively slow working cycle times and, in addition, a machined fabric part has to be removed from the bow bar practically by hand, a perfect pull-in of the fabric parts is not guaranteed because the fabric moves very easily on the bow bar shifted one or the other side and then a perfect result when ironing out the seam cannot be achieved.

OFFENBARUNG DER ERFINDUNGDISCLOSURE OF THE INVENTION

Der Erfindung liegt die Aufgabe zugrunde, für einen Nahtbügelplatz zum automatischen Ausbügeln von Stoffnähten eine weitere Lösung anzugeben, die unabhängig von der Stoffart und der Stoffstärke ein stets einwandfreies schnelles Einziehen des Stoffguts zwischen den Bügelholm und den Oberholm sowie ein stets einwandfreies schnelles Herausführen des Stoffguts aus dem Spalt zwischen dem Bügelholm und dem Oberholm nach Ausführung des Bügelvorgangs sicherstellt.The invention has for its object to provide a solution for a seam ironing for automatic ironing of fabric seams that regardless of the type of fabric and the thickness of the fabric always a perfect fast pulling in between the handlebar and the upper spar and always flawless quick removal of the fabric the gap between the handlebar and the upper handle after performing the ironing process.

Ausgehend von einem Nahtbügelplatz der eingangs erwähnten Art, wird diese Aufgabe gemäß der Erfindung durch die im Patentanspruch 1 angegebenen Merkmale gelöst.Starting from a seam ironing place of the type mentioned at the outset, this object is achieved according to the invention by the features specified in claim 1.

Der Erfindung liegt die Erkenntnis zugrunde, daß gerade durch die Kombination eines Förderbandes, auf dem das Stoffgut zwischen die Holme ein- und wieder ausgefahren wird, in Verbindung mit einem Stoffrandhalter, der das in die Stoffnaht-Einfädelvorrichtung eingeführte Stoffgut randseitig festhält und die Bewegung des Förderbandes mitmacht, in außerordentlich vorteilhafter Weise erreicht wird, daß unterschiedliche Haftreibung zwischen dem Stoffmaterial und der Oberseite des Förderbandes sowie in Abhängigkeit der Stoffstärke schwankende Reibu ngswiderstände zwischen dem Stoffgut und der Stoffnaht-Einfädelvorrichtung praktisch keinen Einfluß auf die exakte Führung des Stoffguts zwischen den Holmen mehr ausüben können. Außerdem ermöglicht gerade das zusätzliche Festklemmen des Stoffrandes im Zeitraum einer Verfahrbewegung zwischen den Holmen wesentlich höhere, einen Arbeitszyklus entsprechend verkürzende Verfahrgeschwindigkeiten.The invention is based on the knowledge that just by the combination of a conveyor belt on which the fabric is moved in and out between the spars, in conjunction with a fabric edge holder which holds the fabric introduced into the fabric threading device on the edge and the movement of the Conveyor belt participates, is achieved in an extremely advantageous manner that different static friction between the material and the top of the conveyor belt and depending on the fabric thickness fluctuating friction resistances between the fabric and the fabric threading device practically no influence on the exact guidance of the fabric between the bars can exercise. In addition, the additional clamping of the fabric edge in the period of a movement between the spars enables significantly higher travel speeds that shorten a work cycle.

Vorteilhafte Ausgestaltungen des Stoffrandhalters sind in den Patentansprüchen 2 bis 4 angegeben.Advantageous embodiments of the fabric edge holder are specified in claims 2 to 4.

In Weiterbildung der Erfindung sind in den weiteren Patentansprüchen 6 bis 8 eine vorteilhafte Ausgestaltung einerseits des Aufnahmeholms und andererseits der Hubeinrichtung für die Auf-Abbewegung der Formpreßplatte angegeben, die neben einem schnellen Einführen des Stoffguts zwischen die Holme auch ein schnelles Auswerfen des gebügelten Stoffguts zusätzlich unterstützen und darüber hinaus in sich gekrümmten Stoffnähten Rechnung tragen.In a further development of the invention, in the further claims 6 to 8 an advantageous embodiment of the holding spar on the one hand and the lifting device for the up-down movement of the compression plate on the other hand are specified, which in addition to rapid insertion of the material between the spars also support rapid ejection of the ironed material and also take into account curved fabric seams.

In einer anderen Weiterbildung ist in den weiteren Patentansprüchen 9 bis 13 eine vorteilhafte Ausgestaltung der Stoffnaht-Einfädelvorrichtung angegeben, die nicht nur schnell an unterschiedliche Stoffstärken anpaßbar ist, sondern auch ein schnelles und stets sicheres Einfädeln des hinsichtlich seiner Stoffnaht auszubügelnden Stoffgutes gewährleistet.In another development, an advantageous embodiment of the fabric threading device is specified in the further claims 9 to 13, which is not only quickly adaptable to different fabric thicknesses, but also ensures fast and always safe threading of the fabric to be ironed with regard to its fabric seam.

Der Nahtbügelplatz nach Fig.1 weist einen Ständer 1 mit einem Ständerfuß 2 auf, der über Rollen 3 und 4 ein leichtes Verschieben des Nahtbügelplatzes ermöglicht. Der Ständer 1 mündet in einen Ständerkopf 5 aus, an dem ein Bügelholm 6 mit einem ihn an seinem freien Ende verlängernden, leicht nach unten gekrümmten Aufnahmeholm 7 und einem darüber angeordneten Oberholm 8 befestigt sind. Der Oberholm 8 trägt an seinem freien Ende eine im Zusammenhang mit den Figuren 5 bis 7 noch näher zu beschreibende Stoffnaht-Einfädelvorrichtung 9, der an der Vorderseite eine im wesentlichen nach vorn unten ausgerichtete Luftdüse 9a zugeordnet ist. Weiterhin ist der Oberholm 8, der am Ständerkopf 5, wie das der Doppelpfeil andeutet, in der Höhe verstellbar. Nach unten ist der Oberholm 8 offen und enthält einen mit seiner elektrischen Heizung versehenen Formpreßkörper 10, dessen nach unten offene Dampfkammer 11 mit einer Formpreßplatte 13 abgeschlossen ist. Diese Formpreßplatte weist Dampföffnungen 12 in Form einer Lochreihe auf. Der beheizte Formpreßkörper 10 ist einschließlich der Dampfkammer 11 gegen den Oberholm 8 hin mit einer Wärmeisolationsschicht 14 umgeben, und durch eine Hubeinrichtung in Form eines am Oberholm befestigten Andruckzylinder (16) über die Kolbenstange 15 in Vertikalrichtung im Oberholm 8 verschiebbar angeordnet.1 has a stand 1 with a stand foot 2, which enables the stirrup place to be easily moved via rollers 3 and 4. The stand 1 opens into a stand head 5, to which a stirrup bar 6 is fastened with a receiving spar 7 which extends at its free end and is slightly curved downwards, and an upper bar 8 arranged above it. The upper spar 8 carries at its free end a fabric seam threading device 9 which is to be described in more detail in connection with FIGS. 5 to 7 and to which an air nozzle 9a which is oriented substantially downwards at the front is assigned. Furthermore, the height of the upper spar 8, which is indicated on the stand head 5, as indicated by the double arrow, is adjustable. The upper spar 8 is open at the bottom and contains a molded body 10 provided with its electric heater, the steam chamber 11 of which is open at the bottom and is closed by a molded plate 13. This compression plate has steam openings 12 in the form of a row of holes. The heated compression body 10, including the steam chamber 11, is surrounded with a heat insulation layer 14 against the upper spar 8, and is displaceably arranged in the vertical direction in the upper spar 8 by means of a lifting device in the form of a pressure cylinder (16) attached to the upper spar.

Der als Absaugwanne gestaltete Bügelholm 6 ist mit einem Förderband 17 augestattet, das über eine Antriebsrolle 18, eine Umlaufrolle 19 und eine in Nähe der Antriebsrolle 18 angeordnete Andruckrolle 20 in Erstreckung des Bügelholms 6 umläuft, und an der Oberseite des Bügelholms in Verbindung mit einer Silikon-Kautschukauflage die Bügelauflage an der Oberseite des Bügelholms 6 bildet.The bracket 6 designed as a suction pan is equipped with a conveyor belt 17, which rotates in the extension of the bracket 6 via a drive roller 18, a rotating roller 19 and a pressure roller 20 arranged in the vicinity of the drive roller 18, and on the top of the bracket in connection with a silicone - Rubber pad forms the bracket pad on the top of the bracket 6.

Am Förderband 17 ist in dessen Grundarbeitsstellung unmittelbar hinter der Stoffnaht-Einfädelvorrichtung 9 ein Stoffrandhalter 21 vorgesehen, der die Bewegung des Förderbandes 17 beim Einziehen oder Ausführen des Stoffgutes mitmacht und das Stoffgut an seinem vorderen Rand gegen das Förderband festklemmt.On the conveyor belt 17, a fabric edge holder 21 is provided in its basic working position immediately behind the fabric threading device 9, which takes part in the movement of the conveyor belt 17 when the fabric is being pulled in or out and clamps the fabric at its front edge against the conveyor belt.

Für die Zuführung von Wasserdampf in die Dampfkammer 11 des Formpreßkörpers 10 im Bereich des Oberholms 8 ist am Ständerkopf 5 in entsprechender Höhe ein Magnetventil 22 angeordnet, das über eine Schlauchleitung 23 mit dem Dampferzeuger 24 in Verbindung steht. Der Dampferzeuger 24 muß nicht, wie in Fig.1 angedeutet, mit dem Ständerfuß 2 des Ständers 1 fest verbunden sein. Er kann vielmehr auch frei aufgestellt sein. Mit dem Ständer 1 bzw. dessen Fuß fest verbunden ist das Gebläse 25, das über einen nicht näher dargestellte Leitung mit der Absaugwanne des Bügelholms 6 in Verbindung steht. Weiterhin zeigt Fig.1 einen Preßlufterzeuger 30, der über Magnetventile 22a und 22b hinweg dem Aufnahmeholm 7 und der Stoffnaht-Einfädelvorrichtung 9 Preßluft zuführt.For the supply of water vapor into the steam chamber 11 of the molded body 10 in the region of the upper beam 8, a magnetic valve 22 is arranged on the stator head 5 at an appropriate height, which is connected to the steam generator 24 via a hose line 23. The steam generator 24 does not have to be firmly connected to the stand base 2 of the stand 1, as indicated in FIG. Rather, it can also be set up freely. The blower 25, which is connected to the suction trough of the stirrup member 6 via a line (not shown in detail), is firmly connected to the stand 1 or its base. 1 also shows a compressed air generator 30, which feeds compressed air via magnetic valves 22a and 22b to the receiving spar 7 and the fabric seam threading device 9.

Wie Fig.1 ferner zeigt, ist am Ständerkopf 5, und zwar an dessen Oberseite, noch eine Haltebügel 26 schwenkbar angeordnet, an deren freiem Ende im Bereich der Stoffnaht-Einfädelvorrichtung 9 die Steuer-Bedieneinheit 27 befestigt ist. Die Steuer-Bedieneinheit 27 weist eine Reihe von Bedienknöpfen 28 auf, mit deren Hilfe die gewünschten Zykluszeiten für einen Nahtbügelvorgang eingestellt werden können. Die Steuer-Bedieneinheit 27 enthält darüber hinaus die Elektronik für die Steuerung des Gebläses 25, die Magnetventile 22, 22a und 22b, den Andruckzylinder 16 der Hubeinrichtung, die Stoffnaht-Ein fädelvorrichtung 9, den steuerbaren Stoffrandhalter 21 sowie den Antrieb für das Förderband 17.As further shown in FIG. 1, a holding bracket 26 is pivotally arranged on the stand head 5, specifically on the upper side thereof, at the free end of which the control operating unit 27 is fastened in the region of the fabric threading device 9. The control operating unit 27 has a number of operating buttons 28, by means of which the desired cycle times for a seam ironing process can be set. The control and operating unit 27 also contains the electronics for the control of the blower 25, the solenoid valves 22, 22a and 22b, the pressure cylinder 16 of the lifting device, the fabric seam threading device 9, the controllable fabric edge holder 21 and the drive for the conveyor belt 17th

Für den Start und die Unterbrechung eines Arbeitszykluses befindet sich am Boden neben dem Ständerfuß 2 des Ständers 1 noch ein Fußschalter 29, der mit der Steuer-Bedieneinheit 27 über ein im Ständer 1 und im Haltebügel 26 geführtes Kabel 29a verbunden ist.For starting and interrupting a work cycle, there is also a foot switch 29 on the floor next to the stand base 2 of the stand 1, which is connected to the control operating unit 27 via a cable 29 a guided in the stand 1 and in the retaining bracket 26.

Der Nahtbügelarbeitsplatz nach Fig.1 zeigt nur eine Bügelholm-Oberholmkombination am Ständer 1. Es ist jedoch festzustellen, daß es im Hinblick auf eine optimale Arbeitsplatzgestaltung sinnvoll ist, am Ständer 1 nebeneinander in einem vorgegebenen Abstand zwei solcher Holmkombinationen vorzusehen, die von einer Bedienperson wechselweise mit hinsichtlich seiner Naht auszubügelndem Stoffgut beschickt werden können. Dabei können der Dampferzeuger 24, das Gebläse 25 und der Preßlufterzeuger 30 beiden Holmenanordnungen gemeinsam zugeordnet sein.The seam stirrup workstation according to FIG. 1 shows only one stirrup-top stile combination on the stand 1. It should be noted, however, that in view of an optimal workplace design it is useful to provide two such stile combinations next to each other at a predetermined distance on the stand 1, which are alternately used by one operator can be loaded with material to be ironed out with regard to its seam. The steam generator 24, the blower 25 and the compressed air generator 30 can be assigned to both spar arrangements together.

Wie die ausschnittsweise Darstellung des Aufnahmeholms 7 nach Fig.1 in Fig.2 näher erkennen läßt, ist dieser als Rohr 7a ausgeführt, das an seinem freien Ende in einen bugförmigen Abschluß ausmündet.As can be seen in more detail in the detail of the receiving spar 7 according to FIG. 1 in FIG. 2, this is designed as a tube 7a which opens out into a bow-shaped end at its free end.

Um beim Herausführen des hinsichtlich seiner Naht ausgebügelten Stoffguts die Gleitreibung über den Aufnahmeholm 7 hinweg möglichst klein zu halten, ist der Hohlraum des Rohrs 7a mit dem Preßlufterzeuger 30 verbunden und weist an der Rohroberseite Luftöffnungen 7b auf, die schräg nach oben zum freien Ende des Aufnahmeholms 7 hin ausgerichtet sind und durch die hindurch beim Auswerfen des Stoffguts Blasluft gegen das Stoffgut ausströmt.In order to keep the sliding friction over the receiving spar 7 as small as possible when the fabric material ironed out with regard to its seam, the cavity of the tube 7a is connected to the compressed air generator 30 and has air openings 7b on the upper side of the tube, which are inclined upwards to the free end of the receiving spar 7 are aligned and through which blown air flows out against the material when the material is ejected.

Wie die Seitenanschicht des Stoffrandhalters 21 nach Fig.3 und die Aufsicht auf den Stoffrandhalter 21 nach Fig.4 erkennen lassen, weist dieser eine Grundplatte 31 auf, die am Förderband 17 mit Nieten 32 befestigt ist.Like the side layer of the fabric edge holder 21 according to FIG. 3 and the top view of the fabric edge neck ter 21 according to Figure 4, this has a base plate 31 which is fastened to the conveyor belt 17 with rivets 32.

Die Grundplatte 31 steht auf beiden Seiten über das Förderband 17 über und weist in diesem Bereich nach oben abgewinkelte Enden auf, an denen auf beiden Seiten jeweils einer der Antriebszylinder 35 befestigt ist.The base plate 31 projects over the conveyor belt 17 on both sides and has in this area ends that are angled upwards, to each of which one of the drive cylinders 35 is fastened on both sides.

Dem Stoffrandhalter 21 ist auf der Vorderseite eine senkrecht zur Bewegungsrichtung des Förderbandes 17 ausgerichtete Stoffanschlagkante 33 zugeordnet, über die hinweg wenigstens zwei Klemmfinger 34 übergreifen. Die Klemmfinger 34 sind an einem das Förderband 17 überspannenden Bügel 34a befestigt und klemmen den bis zur Stoffanschlagkante 33 durch die Stoffnaht-Einfädelvorrichtung 9 hindurch geführten, in seiner Naht auszubügelnden Stoff am Rande gegen das Förderband 17 fest. Die Betätigung des Bügels 34a mit den Klemmfingem 34 erfolgt mit Hilfe der Antriebszylinder 35, durch die eine lineare horizontale Bewegung über ein mit den Enden des Bügels 34a verbundenes Gestänge 36 in eine um eine horizontale Achse drehbare Bewegung des Bügels 34a mit den Klemmfingern 34 umgesetzt wird.On the front, the fabric edge holder 21 is assigned a fabric stop edge 33 which is oriented perpendicular to the direction of movement of the conveyor belt 17 and over which at least two clamping fingers 34 overlap. The clamping fingers 34 are fastened to a bracket 34 a spanning the conveyor belt 17 and clamp the fabric to be ironed out up to the fabric stop edge 33 through the fabric seam threading device 9 against the conveyor belt 17. The actuation of the bracket 34a with the clamping fingers 34 takes place with the aid of the drive cylinders 35, by means of which a linear horizontal movement via a linkage 36 connected to the ends of the bracket 34a is converted into a movement of the bracket 34a rotatable about a horizontal axis with the clamping fingers 34 .

Die Stoffanschlagkante 33 ist zweckmäßig Bestandteil der Grundplatte 31, so daß von ihrer speziellen Befestigung am Förderband Abstand genommen werden kann.The fabric stop edge 33 is expediently part of the base plate 31, so that it can be removed from its special attachment to the conveyor belt.

Die in den Fig.5, 6 und 7 in Frontsicht, Seitensicht und Aufsicht dargestellte Stoffnaht-Einfädelvorrichtung 9, besteht aus dem Hubzylinder 37 sowie einem die eigentliche Stoffnaht-Einfädelvorrichtung aufnehmenden Führungskörper 38. Der Hubzylinder 37 ist dabei an der Unterseite über sein Kolbengestänge 39 mit dem Führungskörper 38 fest verbunden. Der Hubzylinder 37 geht an seiner Unterseite in einen Ringflansch 37a über, mit dem er in eine Öffnung 40 in der Wandung 41 des Oberholms eingreift und hiergegen mittels der Ringmutter 42 verschraubt ist.The fabric seam threading device 9 shown in FIGS. 5, 6 and 7 in front view, side view and top view consists of the lifting cylinder 37 and a guide body 38 which receives the actual fabric seam threading device. The lifting cylinder 37 is on the underside via its piston rod 39 firmly connected to the guide body 38. The underside of the lifting cylinder 37 merges into an annular flange 37a, with which it engages in an opening 40 in the wall 41 of the upper spar and is screwed against it by means of the ring nut 42.

Der Führungskörper 38 weist eine Kopfplatte 43 auf, die über zwei zueinander parallele Abstandsbuchsen 44 und 45 mit einer Fußplatte 46 verbunden sind. Die Verbindung zwischen der Kopfplatte 43 und der Fußplatte 46 über die Abstandsbuchsen 44 und 45 kann, wie das die in Fig.5 dargestellte Frontsicht der Stoffnaht-Einfädelvorrichtung 9 zeigt, mittels Schrauben 47 erfolgen.The guide body 38 has a head plate 43 which is connected to a foot plate 46 via two mutually parallel spacer bushings 44 and 45. The connection between the head plate 43 and the foot plate 46 via the spacer bushings 44 and 45 can, as shown in the front view of the fabric seam threading device 9 shown in FIG. 5, take place by means of screws 47.

An der Unterseite des Führungskörpers 38 befindet sich ein mit einem Querbolzen 48 versehener blockförmiger Nahtumleger 49, der am unteren Ende eines Führungsbolzens 51 befestigt ist. Der Führungsbolzen 51 ist in einer nicht näher dargestellten Bohrung in der Fußplatte 46 geführt, ragt mit seinem oberen Ende durch die Fußplatte 46 hindurch und geht an diesem seinem Ende in einen Hubkopf 52 über. Mit diesem Hubkopf steht der Führungsbolzen mit einem Exzenter 53 in Verbindung, der Teil der Stellvorrichtung 54 ist. Der Exzenter 53 ist hierbei am Ende einer horizontalen Achse 55 befestigt, die drehbar in einem an der Fußplatte befestigten Lageraufsatz 56 gehaltert ist und an ihrem anderen, aus dem Führungskörper nach vorne herausragenden Ende einen Einstellknopf 55a aufweist. Durch Drehen des Einstellknopfes 55a und damit durch Drehen des Exzenters 53 läßt sich je nach Gestaltung der Exzenterscheibe eine kontinuierliche oder schrittweise Höhenverstellung des Nahtumlegers 50 gegen den Druck der Druckfeder 57 herbeiführen. Die Druckfeder 57 ist im Führungsbolzen 51 gelagert und stützt sich mit ihren Enden gegen die Oberseite des Nahtumlegers 49 einerseits und die Unterseite der Fußplatte 56 andererseits ab.On the underside of the guide body 38 there is a block-shaped seam fold 49 provided with a cross bolt 48, which is attached to the lower end of a guide bolt 51. The guide pin 51 is guided in a bore (not shown in detail) in the base plate 46, protrudes with its upper end through the base plate 46 and merges at this end into a lifting head 52. With this lifting head, the guide pin is connected to an eccentric 53, which is part of the adjusting device 54. The eccentric 53 is in this case fastened to the end of a horizontal axis 55 which is rotatably held in a bearing attachment 56 fastened to the footplate and has an adjusting knob 55a at its other end which projects forward from the guide body. By turning the adjusting knob 55a and thus by turning the eccentric 53, depending on the design of the eccentric disk, a continuous or gradual height adjustment of the seam fold 50 against the pressure of the compression spring 57 can be brought about. The compression spring 57 is mounted in the guide bolt 51 and is supported with its ends against the upper side of the seam fold 49 on the one hand and the underside of the foot plate 56 on the other hand.

Der blockförmige Nahtumleger 49 geht an seiner Vorderseite in einen Kiel 50 über, der wiederum in ein Nahttrennschwert 50a ausmündet. Dem Nahttrennschwert 50a ist auf beiden Seiten eine kufenförmige Stoffnaht-Seitenführung 58 zugeordnet. Jede der Stoffnaht-Seitenführungen 58 ist über einen Verbindungsschenkel 59 mit einer Lagerplatte 60 verbunden, die an ihrem unteren Ende in einer Bohrung 61 auf dem Querbolzen 48 verschiebbar geführt ist. Weiterhin weisen die Lagerplatten 60 an ihrer Oberseite einen Keilkopf 62 auf, dessen nach unten verlaufende Schrägfläche gegen den Nahtumleger 49 ausgerichtet ist. Mit diesem ihrem Keilkopf 62 sind die beiden Lagerplatten 60 auf beiden Seiten des Nahtumlegers 49 in seitlichen entsprechend gestalteten Keilnuten 63 der Fußplatte 46 in vertikaler Richtung verschiebbar geführt. Auf diese Weise wird erreicht, daß bei einer vertikalen Relativbewegung des Nahtumlegers 49 mit Hilfe der Stellvorrichtung 54 gleichzeitig eine gegensinnige horizontale Spreizbewegung der Stoffnaht-Seitenführungen 58 ausgeführt wird. Bei Gestaltung der aufeinander gleitenden Schrägflächen des Keilkopfes 62 der Lagerplatten 60 in den Keilnuten 63 unter einem Winkel von 45° wird dabei gewährleistet, daß das Verhältnis einer vorgegebenen Änderung des Abstands des Nahtumlegers 49 relativ zum Führungskörper 38 stets eine gleiche horizontale Abstandsänderung einer Stoffnaht-Seitenführung 58 relativ zum Nahttrennschwert 50a ausführt. Die Stellvorrichtung 54 ermöglicht es also, die Stoffnaht-Einfädelvorrichtung 9 in wünschenswerter Weise schnell mit einem Handgriff an unterschiedliche Stoffstärken anzupassen.The block-shaped seam fold 49 merges into a keel 50 on its front side, which in turn opens into a seam separating sword 50a. A runner-shaped fabric side guide 58 is assigned to the seam separating sword 50a on both sides. Each of the fabric seam side guides 58 is connected via a connecting leg 59 to a bearing plate 60 which is guided displaceably at its lower end in a bore 61 on the cross bolt 48. Furthermore, the bearing plates 60 have a wedge head 62 on their upper side, the downward sloping surface of which is aligned with the seam fold 49. With this wedge head 62, the two bearing plates 60 on both sides of the seam flap 49 are slidably guided in the side in correspondingly shaped keyways 63 of the foot plate 46 in the vertical direction. In this way it is achieved that with a vertical relative movement of the seam fold 49 with the help of the adjusting device 54 an opposite horizontal spreading movement of the fabric side guides 58 is carried out at the same time. When designing the sliding surfaces of the wedge head 62 of the bearing plates 60 in the keyways 63 at an angle of 45 ° , it is ensured that the ratio of a predetermined change in the distance of the seam fold 49 relative to the guide body 38 always results in the same horizontal change in distance of a fabric side guide 58 relative to the seam separating sword 50a. The adjusting device 54 thus makes it possible, in a desirable manner, to quickly adapt the fabric seam threading device 9 to different fabric thicknesses with one movement.

Die in Abhängigkeit einer Vertikalbewegung des Nahtumlegers 49 relativ zum Führungskörper 38 ausgeführte gegensinnige horizontale Bewegung der Stoffnaht-Seitenführungen 58 erfolgt gegen die Kraft der Zugfeder 64, die die beiden Lagerplatten 60 miteinander verbindet. Die lagerplattenseitige Befestigung der Zugfeder 64 erfolgt dabei in der Weise, daß die Zugfeder 64 mit ihren Enden jeweils durch eine Bohrung 65 im Mittelteil der Lagerplatten 60 hindurchragt und an der Außenseite der Lagerplatten 60 jeweils in einem Splint 66 gehaltert ist.The opposite horizontal movement of the fabric seam side guides 58, which is carried out as a function of a vertical movement of the seam fold 49 relative to the guide body 38, takes place against the force of the tension spring 64, which connects the two bearing plates 60 to one another. The mounting of the tension spring 64 on the bearing plate side is carried out in such a way that the ends of the tension spring 64 each protrude through a bore 65 in the central part of the bearing plates 60 and are each held in a split pin 66 on the outside of the bearing plates 60.

Wie die Aufsicht auf die Stoffnaht-Einfädelvorrichtung 9 in Fig.7 noch erkennen läßt, ragt das Nahttrennschwert 50b mit seiner Schwertspitze über die freien Enden der Stoffnaht-Seitenführungen 58 hinaus und weist, wie die Seitenansicht der Stoffnaht-Einfädelvorrichtung 9 nach Fig.6 zeigt, eine schräg nach unten abfallende vordere Kante auf. Außerdem sind die kufenförmigen Stoffnaht-Seitenführungen 58 an ihren freien Enden auf seiten des Nahttrennschwerts 50a keilförmig verjüngt. Dadurch wird in außerordentlich vorteilhafter Weise erreicht, daß das von Hand durchzuführende Einfädeln der Stoffnaht des in seiner Stoffnaht auszubügelnden Stoffgutes stets leicht und schnell vorgenommen werden kann.As can be seen from the top view of the fabric seam threading device 9 in FIG. 7, the seam separating sword 50b projects with its sword tip beyond the free ends of the fabric seam side guides 58 and points, as the side view of the fabric seam threading device 9 according to FIG. 6 shows , a leading edge sloping downwards. In addition, the runner-shaped fabric side guides 58 are tapered at their free ends on the side of the seam separating sword 50a. It is thereby achieved in an extremely advantageous manner that the manual threading of the fabric seam of the fabric to be ironed in its fabric seam can always be carried out easily and quickly.

Während des Einfädelvorgangs der Stoffnaht eines in der Stoffnaht auszubügelnden Stoffgutes und während des Einzugs des Stoffes nach seiner Festklemmung im Stoffrandhalter 21 mittels der Förderbandes 17 zwischen den Bügel- und den Oberholm, befindet sich die Stoffnaht-Einfädelvorrichtung 9 unmittelbar über dem Förderband 17 in einem durch die Stoffstärke des zu bearbeitenden Stoffes vorgegebenen Abstand.During the threading process of the fabric seam of a material to be ironed out in the fabric seam and during the pulling in of the fabric after it is clamped in the fabric edge holder 21 by means of the conveyor belt 17 between the bracket and the upper spar, the fabric seam threading device 9 is located directly above the conveyor belt 17 in a through the material thickness of the specified distance to be processed.

Weiterhin befindet sich der vom Formpreßkörper 10 im Oberholm 8 in seiner ersten Ruhestellung, in der die Unterseite seiner Formpreßplatte 13 etwa 5 mm Abstand zum Förderband 17 aufweist. Hierdurch ist gewährleistet, daß die beim Durchgang durch die Stoffnaht-Einfädelvorrichtung 9 umgelegte Stoffnaht sich während des Einziehens zwischen die Holme nicht wieder aufrichten kann. Nach Durchführung des Bügelpreßvorgangs, bei dem der Formpreßkörper 13 auf den auf dem Förderband 17 aufliegenden Stoff abgesenkt wird, wird der Formpreßkörper 10 in seine zweite Ruhestellung angehoben, in der er sich mit der Unterseite seinerFormpreßplatte 13 etwa 15 mm über dem Förderband befindet. Gleichzeitig und gegebenenfalls auch schon vorweg wird der die eigentliche Stoffnaht-Einfädelvorrichtung darstellende Führungskörper 38 mit Hilfe des Hubzylinders 37 soweit nach oben gefahren, daß die Stoffnaht-Einfädelvorrichtung den Auswurf des in seiner Naht ausgebügelten Stoffguts nicht behindern kann. Zugleich wird auch durch die zweite Ruhestellung des Formpreßkörpers 10 erreicht, daß das auszuwerfende ausgebügelte Stoffgut einen relativ großen Bewegungsraum zwischen den Holmen vorfindet. Wie schon darauf hingewiesen worden ist, wird das Auswerfen des ausgebügelten Stoffguts zusätzlich durch Blasluft aus den Luftöffnungen 7b an der Oberseite des Aufnahmeholms 7 begünstigt.Furthermore, that of the molded body 10 in the upper beam 8 is in its first rest position, in which the underside of its molded plate 13 has a distance of approximately 5 mm from the conveyor belt 17. This ensures that the fabric seam folded over when passing through the fabric threading device 9 cannot straighten up again during the pulling in between the bars. After performing the ironing process, in which the compression body 13 is lowered onto the fabric lying on the conveyor belt 17, the compression body 10 is raised to its second rest position, in which it is located with the underside of its compression plate 13 about 15 mm above the conveyor belt. Simultaneously and possibly also in advance, the guide body 38, which represents the actual fabric threading device, is moved upwards with the aid of the lifting cylinder 37 so that the fabric seam threading device cannot hinder the ejection of the fabric material ironed in its seam. At the same time, the second rest position of the molded body 10 ensures that the ironed-out material to be ejected finds a relatively large space of movement between the bars. As has already been pointed out, the ejection of the ironed material is additionally promoted by blown air from the air openings 7b on the top of the receiving spar 7.
