Description
Schweißvorrichtung für Bund-, Bein-und andere endlose Nähte an Bekleidungsstücken aus thermoplastischen Kunststoffolien Die Schweißung der Längs- und Beundhähte von Bekleidungsstücken aus thermoplastischen Kunstofffolken, wie Kinderhöschen, eventulle unter Einlage von Gummiband, erfolgte bisher durch eine Vielzahl von Teilschweißungen. Welding device for waistband, leg and other endless seams on items of clothing from thermoplastic plastic films The welding of the longitudinal and bottom seams of Articles of clothing made from thermoplastic sheets of plastic, such as children's panties, possibly with the inlay of rubber band, has been carried out so far by a large number of partial welds.
Bei der Schweißung solcher Nähte in einem Arbeitsgang tritt die Schwierigkeit auf, daß die endlxoe Naht an allen Stellen ohne Unterbrechung zwischen Schweißorgan und Widerlager eingopreßt und erhitzt werden muß. Diese Zusammenpressung darf nicht unter zu großem Druck erfolgen, da hierdurch das Schweißgut bescdhädigt würde, muß andererseits aber unter zu hohem Druck erfolgen, daß eine zufriedenstellende Verschweißng erzielt wird. The difficulty arises when welding such seams in one operation on that the endlxoe seam in all places without interruption between the sweat organ and abutment must be pressed in and heated. This compression must not must be carried out under excessive pressure, as this would damage the weld metal on the other hand take place under too high pressure that a satisfactory weld is achieved.
Die Erfindung löst diese Aufgrabe dadurch, daß das auf einen geleichzeitig als Schweißorgan dienenden heizbaren Aufspannkörper aufgeschobene, zu scfhweißende Teil des Schweißgutes vor dem Schweißen von einem au beiden Enden gehaltenen Umschlingungsband aus hitzebeständigem Gewebe umschlungen und auf dem Aufspannkörper gepreßt wird. Der Aufspannkörper liegt auf einem Schweißtisch. Das Umschlingungsband ist zwischen Aufspannkörper und Tisch hindurchgeführt und verläuft weiter über einen enkrecht stehenden Schwenkarm zum Maschinengestell. Der Schwenkarm wird vor dem Schweißen durch die horizontale Bewegung eines hin-und hergehenden Wagens in Horizontalstellung geschwenkt, zieht dabei das Umschlingungsband über den Aufspannkörper und bewirkt so die vollständige Umschlingung der nahtstelle des Schweißgutes auf dem Aufspannkörper. Durch die gleiche Horizontalbewegung des Wagens wird der Schweißtisch nach oben gegen den Aufspannkörper gedrückt, auf welcfhem nummehr der Schwenkarm aufleigt. Das gespannte Umschlingungsband preßt das Schweißgut gleichmäßig unter nachgiebigem Druck allseitig an den Aufspannkörper an. Das Umschlingungsband wird vorzugsweise durch eine mit dem schwenkarm verbundene Federstütze, über welche es läuft, unter Spannung gehalten. The invention solves this problem in that the one at the same time heatable clamping bodies that are used as welding organs and that are to be welded Part of the weld metal before welding by a strap held at both ends is wrapped in heat-resistant fabric and pressed on the clamping body. The clamping body lies on a welding table. The wrap is between Clamping body and table passed through and continues over a vertical one standing swivel arm to the machine frame. The swivel arm is before welding by the horizontal movement of a reciprocating carriage in a horizontal position pivoted, pulls the belt over the clamping body and causes so the complete wrapping of the seam of the weld metal on the clamping body. The same horizontal movement of the carriage raises the welding table pressed against the clamping body, on which number the swivel arm rests. The tensioned belt presses the weld metal evenly under flexible Pressure on all sides of the clamping body. The wrap is preferred by a spring support connected to the swivel arm, over which it runs, under Tension held.
In weiterer Ausgestaltung der Erfindung kann die Länge des Umschlingungsbandes eingestellt werden, um die Vorrichtung an Aufspannkörper verschiedener Größe anzupassen, wie sie für Schweißnähte und für Bekleidungsstücke verschiecener Größe erforderlich sind. Ferner wird der Schwenkarm nach seiner Bewegung in die Horizontalstellung vorzugsweise durch eine Sperre in dieser Stellung gehalten, wobei die Sperre nach beendeter Schweißung bei rückläufiger Bewegung des Wagens automjatisch weider gelöst wird. In a further embodiment of the invention, the length of the wrapping belt can be adjusted to adapt the fixture to different sizes of fixtures, as required for welding seams and for articles of clothing of various sizes are. Furthermore, the swivel arm is moved into the horizontal position preferably held in this position by a lock, the lock after When the welding is finished, it is automatically released again when the carriage moves backwards will.
Die Druckfläche des Schwenkarmes wie des Schweißtisches ist vorzugsweise mit einem samtüber- zogenen Ausglichespolster versuchen, um das Schweiß -gut zu schonen und die nachgiebigkeit des auf das Schweißugt ausgeübten Druckes zu erhöhen. The pressure surface of the swivel arm as well as the welding table is preferred with a velvet Try to remove the compensation pad in order to protect the weld metal and to increase the resilience of the pressure exerted on the weld joint.
Die Beheizung des Aufspannkörpers kann nach dem an sich bekannten Impulsverfahren wie auch nach dem Hochfrequenzverfahren erfolgen. Im erstgenannten Falle ist der Aufspannkörper in üblicher Weise mit einem elektrischen Heizband umgeben. Vorzugsweise wird auf dasselbe eine Schicht aus einer hitzebeständigen, schlecht wärmeleiten dem Masse aus einem Metalloxyd, wie Aluminium-, Titan-, Magnesium-, Zinkoxyd, Silicaten u. dgl., und auf diese ein hitzebeständiges Gewebe aufgebracht, Zwischen der letztgenanten und der suchlecht wärmeleitenden Schicht ordnet man vorzugsweise ein Metallfolie an. Durch diesen Aufbau wiird eine äußerst gleichmäßige Wärmeübetragung und ein elastischeas, das Schweißgut schonendes Einsetzen des Wärmeimpulses bewirk. Bei Schwweißung mit Hochfrequenz ist der Aufspannkörper von einem endlosen Metallband umgeben und das umschlingungsband als Gegendlektrode ausgebildet, z. B. mit einem Metallgewebe oder einer Metallfolie verschen. The heating of the clamping body can be carried out according to what is known per se Impulse method as well as according to the high frequency method. In the former Case, the clamping body is surrounded in the usual way with an electrical heating tape. Preferably, a layer of a heat-resistant, bad is applied to the same conduct heat to the mass of a metal oxide, such as aluminum, titanium, magnesium, Zinc oxide, silicates, etc., and a heat-resistant fabric applied to them, It is preferable to arrange between the latter and the poorly thermally conductive layer a metal foil. This structure ensures extremely uniform heat transfer and an elastic, gentle onset of the heat pulse on the weld metal. When welding with high frequency, the clamping body is made of an endless metal band surrounded and the wraparound band formed as a counter electrode, for. B. with a Give away metal mesh or a metal foil.
Die Automatisierung der Umschlingung und Anpressung des Schweißungtes an den Aufspannkörper und Lösung der Anspressung nach der Schweäung ermöglicht eiune rasche, zweckmäßige Arbeitsweise unter Erreichung stets einwandfreier Schweißungen. The automation of the wrapping and pressing of the weld on the fixture body and release of the stress after welding enables eiune fast, practical working method, always achieving perfect welds.
