Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Schneiden von Stoff- und/oder von Folienbahnen mit einem ausreichenden Anteil von schmelzfähigen Fasern und zum gleichzeitigen Verschweißen der Schnittkante gemäß dem Oberbegriff des Anspruches 1.The invention relates to a method and Device for cutting fabric and / or Foil webs with a sufficient proportion of meltable fibers and for simultaneous Welding the cut edge according to the generic term of claim 1.
Es ist bereits bekannt, Stoff- und/oder Folienbahnen mittels einer Ultraschallsonotrode in Streifen zu schneiden und die Schnittkanten zu verschweißen bzw. zu verschmelzen. Die bekannte Einrichtung besteht aus einer schwingenden Sonotrode als Schneideinrichtung und aus einer mit dem Schneidmesser der Sonotrode in Wirkverbindung stehenden Kugel als Gegenlager oder einer feststehenden Schneide und einer schwingenden Sonotrode (Prospekt der Firma CALEMARD, FR-42230 Roche-La-Moliere).It is already known to have fabric and / or film webs in strips using an ultrasonic sonotrode cut and weld the cut edges or to merge. The known device consists of a vibrating sonotrode as a cutting device and one with the cutting knife of the sonotrode in Active ball as counter bearing or a fixed cutting edge and a swinging one Sonotrode (brochure from CALEMARD, FR-42230 Roche-La-Moliere).
In der DE 43 03 092 A1 werden ein Verfahren und eine Vorrichtung zur Herstellung eines durch Figurschüsse gemusterten textilen Bandes, insbesondere eines Etikettbandes, aus einer Breitbahn mit schmelzfähigem Fadenwerkstoff beschrieben, bei denen zum Ultraschallschweißen und Ultraschallschneiden von Textilmaterial ein scharfkantiger Amboß und ein Ultraschallgerät mit einem Hornstrahler verwendet werden, wobei der Hornstrahler mit einer flachen Anlagefläche auf die Materialbahn einwirkt. Das zubehandelnde Material wird zwischen dem Amboß und dem Hornstrahler hindurchgeführt und dabei geschnitten und gleichzeitig in einer Randzone neben dem Schnitt verschweißt.DE 43 03 092 A1 describes a method and a Device for producing a figure shot patterned textile tape, especially one Label tape, from a wide web with meltable Thread material described in which Ultrasonic welding and cutting of Textile material a sharp anvil and an Ultrasound device with a horn is used be, the horn with a flat Contact surface acts on the material web. The material to be treated is between the anvil and the Hornblower passed and cut and at the same time in an edge zone next to the cut welded.
Nachteilig ist es bei diesen bekannten Einrichtungen, daß Stoffe mit wechselnden Eigenschaften, z. B. Etikette, nicht in ausreichender Qualität mit einer Schneideinrichtung geschnitten und verschweißt werden können. Das Schneiden von dünnen und von dicken Stoffen erfordert den Einsatz von unterschiedlichen Schneidmessern, d. h., es wird ein Wechsel der Messer notwendig, was insbesondere beim Schneiden von Stoffen mit wechselnden Eigenschaften nicht nur uneffektiv, sondern in vielen Fällen unmöglich ist (Etiketten).It is a disadvantage of these known devices that that substances with changing properties, e.g. B. Etiquette, not of sufficient quality with a Cutting device can be cut and welded can. Cutting thin and thick ones Fabrics require the use of different ones Cutting knives, d. i.e. there will be a change of knives necessary, especially when cutting fabrics with changing properties not only ineffective, but is impossible in many cases (labels).
Von daher ist es Aufgabe der Erfindung, diese Mängel zu beseitigen und ein Verfahren und eine Vorrichtung zu entwickeln, mit dem auch Stoffe mit wechselnden Eigenschaften mit einer Schneideinrichtung in gleichbleibend guter Qualität geschnitten und verschweißt werden können.It is therefore an object of the invention to address these shortcomings to eliminate and a method and an apparatus to develop with which also fabrics with changing Features with a cutter in consistently good quality cut and can be welded.
Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen der Ansprüche 1 und 4.The solution to this problem arises from the Features of claims 1 and 4.
Nach der Erfindung wird das Gegenlager aus einem Körper, z. B. einer Kugel, einer Rolle oder einem Gleitstück mit gekrümmter Oberfläche, gebildet, der sich in einem Langloch eines fest angeordneten Federelementes zwischen zwei Punkten lastabhängig bewegen kann. Die Bewegungsbahn, z. B. der Kugel im Langloch, ist so bemessen, daß sich die Kugel automatisch entsprechend der Materialbeschaffenheit von einem stumpferen in einen schärferen Bereich der Schneideeinrichtung bewegt. Das Material, Stoff- oder Folienbahn, wird immer in den Schneidenbereich geführt, in dem die optimalen Schneide- und Schweiß bedingungen bestehen, so daß mit einer einzigen Schneideeinrichtung, Stoffe mit wechselnden Eigen schaften geschnitten und verschweißt werden.According to the invention, the counter bearing from one Body, e.g. B. a ball, a roller or one Slider with a curved surface, formed, the arranged in a slot in a fixed arrangement Spring element between two points depending on the load can move. The trajectory, e.g. B. the ball in Elongated hole is dimensioned so that the ball automatically according to the material properties from a duller to a sharper area of the Cutting device moves. The material, fabric or Foil sheet, is always in the cutting area led in which the optimal cutting and sweat conditions exist so that with a single Cutting device, fabrics with changing properties shafts are cut and welded.
Das Verschweißen der Schnittkanten erfolgt durch die auf die Materialbahn durch die Schwingungen der Sonotrode eingebrachte mechanische Arbeit, die in Form von Reibung im Material und an dessen Oberfläche in Schmelzwärme umgesetzt wird. Der Anteil der eingebrachten Reibungswärme wird insbesondere von der Geometrie der Kontaktflächen von Sonotrode, Gegenlager und dazwischenliegendem Material bestimmt. Das zuver schweißende Material muß dabei einen ausreichend hohen schmelzfähigen Anteil enthalten.The cutting edges are welded by on the material web through the vibrations of the Sonotrode brought mechanical work in the form of friction in the material and on its surface Heat of fusion is implemented. The share of introduced frictional heat is particularly from the Geometry of contact surfaces of sonotrode, counter bearing and intermediate material determined. That verver welding material must be sufficiently high contain meltable portion.
Es wird eine gleichbleibende Qualität beim Schneiden und Kantenverschweißen von unterschiedlichen Stoffdicken und Stoffqualitäten erreicht, weil sich die Kugellast- und damit stoffabhängig in die Richtung unterschiedlicher Schärfebereiche der Schneide bewegt. Es besteht eine selbstjustierende Regelung zwischen der Kugel, dem Stoff und den Schärfebereichen der Schneideeinrichtung. Der Winkel der Rollebene der Kugel ist einstellbar durch eine Veränderung der Neigung des Federelementes. Damit wird die Rückstellkraft des Gegenlagers justierbar.It becomes a constant quality when cutting and edge welding of different Fabric thicknesses and fabric qualities achieved because of the ball load and thus substance dependent in the Direction of different focus areas of the Cutting edge moves. There is a self-adjusting Regulation between the ball, the substance and the Sharpening areas of the cutting device. The angle the roll plane of the ball is adjustable by a Change in the inclination of the spring element. So that will the restoring force of the counter bearing adjustable.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Merkmalen der Unteransprüche.Further advantageous embodiments of the invention result from the features of the subclaims.
Die Erfindung ist nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Es zeigen:The invention is based on one in the Drawing shown embodiment closer explained. Show it:

Fig. 4 die grafische Darstellung des Bewegungsablaufes der Kugel entlang der Schneide. Fig. 4 shows the graphic representation of the movement of the ball along the cutting edge.
In den Fig. 1, 1a) ist eine Vorrichtung zum Schneiden von Stoff- und/oder Folienbahnen und zum gleich zeitigen Verschweißen der Schnittkante dargestellt, bei der die Schneideeinrichtung 1 aus einer senkrecht zur Bewegung der Stoffbahn 7 schwingenden Sonotrode mit einer Schneide 4 und das Gegenlager 2 aus einer Kugel 3, die in einem Langloch 5 (Fig. 3) eines fest angeordneten Federelementes 6 (Fig. 3) beweglich angeordnet ist, gebildet sind.In Figs. 1, 1a) to an apparatus for the cutting of fabric and / or film webs and for the simultaneous welding of the cut edge is shown, in which the cutting device 1 of a vibrating perpendicular to the movement of the fabric web 7 sonotrode with a cutting edge 4 and the Counter bearing 2 from a ball 3 , which is movably arranged in an elongated hole 5 ( Fig. 3) of a fixed spring element 6 ( Fig. 3).
Die Schneide 4 der Schneideeinrichtung 1 weist unter schiedliche Bereiche B,C auf (Fig. 2), wobei der Bereich C mit der schärferen Schneide 4 (dünnere Schneide 4) zum Schneiden von dicken Stoffen 7 und der Bereich B mit der stumpferen Schneide 4 (dickere Schneide 4) zum Schneiden von dünneren Stoffen 7 geeignet ist. Günstige Ausführungsformen der Schneiden 4 sind in den Fig. 2a) bis 2c) als Unteransicht der Schneide 4 dargestellt. Für die weiteren Betrachtungen ist die kegelförmig ausgeführte Schneide 4 gemäß den Fig. 2, 2a) zugrundegelegt.The cutting edge 4 of the cutting device 1 has different areas B, C ( FIG. 2), the area C with the sharper cutting edge 4 (thinner cutting edge 4 ) for cutting thick substances 7 and the area B with the blunt cutting edge 4 ( thicker cutting edge 4 ) is suitable for cutting thinner fabrics 7 . Favorable embodiments of the cutting edges 4 are shown in FIGS . 2a) to 2c) as a bottom view of the cutting edge 4 . For the further considerations, the conical cutting edge 4 according to FIGS. 2, 2a) is used.
Als Gegenlager 2 ist die Kugel 3 (Prallkörper) in dem Langloch 5 angeordnet, welches in dem Federelement 6 ausgebildet ist. Anstelle der Kugel 3 kann auch eine Rolle als Prallkörper verwendet werden. In beiden Fällen ist die Andruckkraft als konstant anzusehen. Wenn der Prallkörper als z. B. unsymmetrisch gelagerter bzw. ausgeführter Rollkörper ausgebildet wird, dann erfolgt die Bewegung kraftabhängig. In jedem Fall muß das Gegenlager 2 die Bewegung des Prallkörpers 3 zwischen zwei definierten Punkten gewährleisten. Im vorliegenden Ausführungsbeispiel bewegt sich die Kugel 3 im Langloch 5 zwischen den Punkten B und C ent sprechend der Darstellung in der Fig. 4.The ball 3 (impact body) is arranged as a counter bearing 2 in the elongated hole 5 , which is formed in the spring element 6 . Instead of the ball 3 , a roller can also be used as an impact body. In both cases, the pressure force can be regarded as constant. If the impact body as z. B. asymmetrically mounted or executed rolling body, then the movement is force-dependent. In any case, the counter bearing 2 must ensure the movement of the impact body 3 between two defined points. In the present exemplary embodiment, the ball 3 moves in the elongated hole 5 between points B and C accordingly as shown in FIG. 4.
In der Fig. 4 ist der Zusammenhang zwischen der Bewegung der Kugel 3 zwischen den Punkten B und C auf der Schneide 4 der Schneideeinrichtung 1 und der Qualität des Schneid- und des Schweißvorganges graphisch dargestellt. Die Anpreßkraft F (Fig. 1) wird als konstant angesehen.In FIG. 4, the relationship between the movement of the ball 3 between points B and C on the cutting edge 4 of the cutter 1 and the quality of the cutting and the welding operation is graphically illustrated. The contact force F ( Fig. 1) is considered to be constant.
Um bei unterschiedlichen Stoffdicken (bzw. auch Stoff gualitäten) eine gleichbleibend hohe Schneid-Schweiß- Qualität zu erreichen, muß sich die Kugel 3 jeweils zu unterschiedlichen Stellen zwischen den Punkten B-C der Schneide 4 der Schneideeinrichtung 1 hinbewegen.In order to achieve a consistently high cutting-welding quality with different fabric thicknesses (or fabric qualities), the ball 3 must move to different locations between the points BC of the cutting edge 4 of the cutting device 1 .
Die Einstellung der Kugellage zu einer bestimmten Stelle der Schneide 4 in Abhängigkeit von der Stoff dicke bzw.- Qualität erfolgt automatisch.The setting of the ball position at a specific point on the cutting edge 4 as a function of the material thickness or quality is carried out automatically.
In der graphischen Darstellung nach der Fig. 4 wird deutlich, daß sich ein Bereich x-x1 einstellt, in dem bei dünnem und bei dickem Stoff 7 sich ein gleiches Qualitätsniveau bezüglich der Schneid- und der Schweißqualität einstellt.In the graphical representation according to FIG. 4, it is clear that an area x-x1 is established, in which the same quality level with regard to the cutting and welding quality is established for thin and thick material 7 .
In der Fig. 4 ist auf der Abszisse d die Lage der Kugel 3 zur Schneide 4 zwischen den Punkten B und C ("B" entspricht der breiten und "C" der schmalen Schneide 4) und auf der Koordinate a die Schneidequalität, beginnend im Nullpunkt mit "schlecht" und aufsteigend zu "gut", und auf der Koordinate b in gleicher Weise und Richtung die Schweißqualität von "schlecht" aufsteigend zu "gut" dargestellt.In FIG. 4, the abscissa d the position of the ball 3 to the cutting edge 4 between the points B and C ( "B" corresponds to the broad and "C" of the narrow cutting edge 4) and on the coordinate A, the cutting quality, beginning in Zero point with "bad" and ascending to "good", and on the coordinate b in the same way and direction the welding quality from "bad" ascending to "good" is shown.
Die Geraden a1, a2 kennzeichnen unterschiedliche Schneidequalitäten, die Geraden b1, b2 kennzeichnen unterschiedliche Schweißqualitäten für a1, b1 bei dünnem Stoff 7 und für a2, b2 bei dickem Stoff 7. Die Schnittpunkte x, x1 der Geraden a1 mit der Geraden b1 (dünner Stoff 7) und der Geraden a2 mit der Geraden b2, bezeichnen den Bereich x-x1, in welchem gleiches Qualitätsniveau für dünnen und dicken Stoff 7 erreicht ist, wie bereits ausgeführt. The straight lines a1, a2 indicate different cutting qualities, the straight lines b1, b2 indicate different welding qualities for a1, b1 with thin fabric 7 and for a2, b2 with thick fabric 7 . The intersection points x, x1 of the straight line a1 with the straight line b1 (thin material 7 ) and the straight line a2 with the straight line b2 denote the area x-x1, in which the same quality level is achieved for thin and thick material 7 , as already stated.
Der geschilderte graphische Verlauf gilt nur für die kegelförmige Ausgestaltung der Schneide 4, bei anderen Ausführungsformen ergeben sich Kurvenverläufe.The graphical course described applies only to the conical configuration of the cutting edge 4 ; in other embodiments there are curve courses.
Je dicker oder fester der Stoff 7 ist, umso schwerer läßt er sich schneiden. Wenn der Stoff 7 durch die Schneide 4 der Schneideeinrichtung 1 nicht durch dringen kann, dann wird die Kugel 3 durch den Stoff 7 vom Punkt B in Richtung zum Punkt C auf der Schneide 4 (Fig. 2a) solange mitgenommen, bis die Schneide 4 den Stoff 7 durchschneidet (Haftreibung zwischen Kugel 3 und Stoff 7).The thicker or firmer the fabric 7 , the harder it is to cut. If the material 7 cannot penetrate through the cutting edge 4 of the cutting device 1 , then the ball 3 is taken along by the material 7 from point B in the direction of point C on the cutting edge 4 ( FIG. 2a) until the cutting edge 4 Cut through fabric 7 (static friction between ball 3 and fabric 7 ).
Durch die schmaler werdende Schneide 4 wird der Stoff 7 besser durchdrungen und somit geschnitten (Fig. 2, 2a)).Due to the narrowing edge 4 , the fabric 7 is better penetrated and thus cut ( Fig. 2, 2a)).
Wenn der Stoff 7 wieder dünner wird, dann wird die Kugel 3 durch das Gegenlager 2 zurück in den Ausgangs punkt B gedrückt.When the fabric 7 becomes thinner again, the ball 3 is pressed back through the counter bearing 2 into the starting point B.
Die Rückstellkraft kann durch eine unterschiedliche Schrägstellung des Gegenlagers 2 verändert bzw. eingestellt werden.The restoring force can be changed or set by a different inclination of the counter bearing 2 .
