Beschreibung description

Die Erfindung betrifft eine Anordnung gemäss Oberbegriff von Anspruch 1, ein Verfahren gemäss Oberbegriff von Anspruch 4 und eine Vorrichtung gemäss Oberbegriff von Anspruch 5. The invention relates to an arrangement according to the preamble of claim 1, a method according to the preamble of claim 4 and a device according to the preamble of claim 5.

Wickel oder Rollen mit aufgewickeltem Wickelgut, z.B. Schnüren, Bändern, Garn, Fäden und dergleichen, werden häufig zur Lagerung, zum Transport oder zum Verkauf zu Anordnungen zusammengefügt, in denen zwei oder mehrere Wickelkörper lösbar miteinander verbunden sind. Dies geschieht häufig durch Zusammenfügen mittels Schrumpfschläuchen oder Blisterpackungen, durch Abpacken in Kartons und dergleichen. In allen Fällen wird dabei Verpackungsmaterial verbraucht, das dann vom Verbraucher zu entsorgen ist. Reels or rolls with wound material, e.g. Laces, ribbons, yarn, threads and the like are often put together for storage, transport or sale in arrangements in which two or more winding bodies are detachably connected to one another. This is often done by joining together using shrink sleeves or blister packs, by packing them in boxes and the like. In all cases, packaging material is consumed, which must then be disposed of by the consumer.

Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung von wenigstens zwei Wickelkörpern sowie ein Verfahren und eine Vorrichtung zum Herstellen derartiger Wickelkörper zu schaffen, die ökonomische Herstellung, Minimierung des Materialverbrauchs und Minimierung des Abfalls bei guter Verbindung der Wickelkörper gewährleistet. The invention has for its object to provide an arrangement of at least two bobbins and a method and an apparatus for producing such bobbins, which ensures economical production, minimization of material consumption and minimization of waste with good connection of the bobbins.

Erfindungsgemäss wird dies durch die Merkmale gemäss Kennzeichen der unabhängigen Patentansprüche erreicht. According to the invention, this is achieved by the features according to the characteristics of the independent claims.

In der Praxis hat sich gezeigt, dass sich die meisten Wickelgüter ohne nachteilige Materialschwächung an ihrer Oberfläche erweichen und plastifizie-ren lassen, so dass nebeneinander liegende Wik-kelkörper nach dem Plastifizieren des Materials zusammengepresst und verschweisst werden können. Voraussetzung dafür ist, dass das Wickelgut wenigstens an der Oberfläche thermoplastisches Material enthält. Dies trifft vor allem für Schnüre und Bänder in vielen Fällen zu. In practice, it has been shown that most of the winding goods can be softened and plasticized on their surface without disadvantageous material weakening, so that adjacent winding bodies can be pressed together and welded after the material has been plasticized. The prerequisite for this is that the material to be wound contains thermoplastic material at least on the surface. This is especially true for cords and ribbons in many cases.

Da die Verschweissung der Materialien nur oberflächlich ist, wird das Wickelgut bei der Trennung nicht zerstört. Since the welding of the materials is only superficial, the material to be wound is not destroyed during the separation.

Obwohl das Verschweissen von thermoplastischem Material selbstverständlich schon seit Jahrzehnten bekannt und in den verschiedensten Anwendungsgebieten gebräuchlich ist, bringt die erfin-dungsgemässe Verbindung wenigstens zweier Wik-kelkörper durch Schweiss-Stellen an einer Mehrzahl voneinander zugewandten Oberflächenpunkten eine überraschende, einfache und wirtschaftliche Lösung für ein ebenfalls seit Jahrzehnten bestehendes, bisher ungelöstes Problem. Although the welding of thermoplastic material has of course been known for decades and is used in a wide variety of fields of application, the connection according to the invention of at least two winding bodies by means of welding points at a plurality of surface points facing one another brings a surprising, simple and economical solution for one as well problem that has existed for decades and has not yet been solved.

Vor allem bei zylindrischen Wickelkörpern lässt sich gute Verbindung erreichen, wenn die Wickelkörper an ihren Stirnseiten miteinander verbunden werden. In the case of cylindrical winding bodies in particular, a good connection can be achieved if the winding bodies are connected to one another at their end faces.

Die Verbindung der Wickelkörper lässt sich besonders gut automatisieren, wenn die zu verbindenden Wickelkörper an einander gegenüberliegenden Oberflächen bis auf die Schweisstemperatur erwärmt und dann zusammengepresst werden. Dies lässt sich besonders einfach durch eine erwärmbare Trennplatte erreichen, gegen welche die Wickelkörper beidseitig und paarweise fluchtend pressbar sind. Die gleiche Einrichtung kann dann dazu dienen, dass nach dem Entfernen der heissen Trennplatte die Paare von Wickelkörpern zusammengepresst und dabei verschweisst werden. The connection of the winding bodies can be automated particularly well if the winding bodies to be connected are heated up to the welding temperature on opposite surfaces and then pressed together. This can be achieved particularly easily by means of a heatable separating plate, against which the winding bodies can be pressed in alignment on both sides and in pairs. The same device can then be used to press the pairs of winding bodies together after welding and remove them while welding.

Selbstverständlich lassen sich mit der Erfindung auch eine Mehrzahl von Wickelkörpern gleichzeitig oder nacheinander verbinden. Of course, the invention can also be used to connect a plurality of winding bodies simultaneously or in succession.

Die Erfindung ist im folgenden in den Ausführungsbeispielen anhand der Zeichnungen näher erläutert. Es zeigen: The invention is explained in more detail below in the exemplary embodiments with reference to the drawings. Show it:

Fig. 1 eine Anordnung von zwei Wickelkörpern, 1 shows an arrangement of two winding bodies,

Fig. 1a die schematische Darstellung einzelner Lagen der Wickelkörper gemäss Fig. 1 mit den Verbindungsstellen, 1a shows the schematic representation of individual layers of the winding body according to FIG. 1 with the connection points,

Fig. 2 bis 4 eine Vorrichtung mit den Merkmalen der Erfindung und 2 to 4 a device with the features of the invention and

Fig. 5 eine abgewandelte Ausführungsform mit einer Vorrichtung mit den Merkmalen der Erfindung. Fig. 5 shows a modified embodiment with a device with the features of the invention.

Gemäss Fig. 1 besteht eine Anordnung 1 aus zwei Wickelkörpern 2 und 3. Die Wickelkörper sind Schnurrollen, die zu Verkaufseinheiten zusammengefügt wurden. Dazu ist die Oberfläche einzelner Schnüre 4 an Schweissstellen 6 miteinander verschweisst. Durch entsprechende Erwärmung der Wickelkörper 2 und 3 und darauf folgendes Zusammenpressen wird die aus Schnurlagen bestehende Oberfläche im Anpressbereich derart elastisch verformt, dass sich an einer Vielzahl von Stellen Berührungsstellen und Schweissverbindungen 6 zwischen einzelnen Schnüren 4 ergeben. Die Wickelkörper 2 und 3 sind damit fest verbunden. Durch die Vielzahl der sich auf diese Weise ergebenden Schweissstellen ist es überraschenderweise auch möglich, die einzelnen Schweissstellen 6 nur oberflächlich so auszubilden, so dass die Schnüre 4 beim Schweissvorgang oder beim Trennen der beiden Wickelkörper 2 und 3 an der Trennstelle 4a nicht beschädigt werden. 1, an arrangement 1 consists of two bobbins 2 and 3. The bobbins are line rollers that have been assembled into sales units. For this purpose, the surface of individual cords 4 is welded together at welding points 6. Appropriate heating of the winding bodies 2 and 3 and subsequent pressing together elastically deforms the surface consisting of layers of cord in the pressing area in such a way that contact points and welded joints 6 between individual cords 4 result at a large number of points. The winding body 2 and 3 are thus firmly connected. Due to the large number of welding points resulting in this way, it is surprisingly also possible to design the individual welding points 6 only superficially so that the cords 4 are not damaged during the welding process or when the two winding bodies 2 and 3 are separated at the separation point 4a.

Fig. 2 zeigt eine Vorrichtung 10 in welche von einer nicht dargestellten Zufuhreinrichtung paarweise Wickelkörper 2, 3 aus der Richtung der Pfeile Z zugeführt werden. Wie auch aus Fig. 3 und 4 ersichtlich ist, besteht die Vorrichtung 10 aus einer Grundplatte 11, zwei seitlichen Lagerungen 12 sowie Anpressplatten 13, die durch Schubstangen 12a, mittels nicht dargestellter Antriebsmotore von den Lagerungen 12 gegen die Wickelkörper 2 und 3 verfahren und gepresst werden können. Zwischen den paarweise fluchtend ausgerichteten Wickelkörpern 2, 3 ist eine Trennplatte 14 vorgesehen, die so erhitzbar ist, dass die an der Oberfläche der Wickelkörper 2 und 3 liegenden Schnüre 4 (Fig. 1) etwa auf Plastifizierungstemperatur gebracht werden können. Fig. 2 und 3 zeigen dabei den Verfahrensschritt, bei welchem die Anpressplatten 12 aus einer gestrichelt dargestellten Ruheposition in die Anpressposition zusammengefahren werden, und dabei die Wickelkörper 2, 3 gegen die heisse Trennplatte 14 gedrückt werden. FIG. 2 shows a device 10 in which winding bodies 2, 3 are fed in pairs from a feed device, not shown, from the direction of the arrows Z. As can also be seen from FIGS. 3 and 4, the device 10 consists of a base plate 11, two lateral bearings 12 and pressure plates 13, which are moved and pressed by push rods 12a by means of drive motors (not shown) from the bearings 12 against the winding bodies 2 and 3 can be. A separating plate 14 is provided between the winding bodies 2, 3, which are aligned in pairs, and which can be heated such that the cords 4 (FIG. 1) lying on the surface of the winding bodies 2 and 3 can be brought to about the plasticizing temperature. 2 and 3 show the method step in which the pressure plates 12 are moved from a rest position shown in dashed lines to the pressure position, and the winding bodies 2, 3 are pressed against the hot separating plate 14.

Die optimale Temperatur der Trennplatte, die Dauer der Erwärmung sowie der optimale Druck beim Erwärmen lassen sich im Einzelfall empirisch mit einigen wenigen Versuchen ermitteln. Dabei kann als Anhaltspunkt die Schmelztemperatur des verwendeten Thermoplasts dienen. Je höher dabei The optimum temperature of the separating plate, the duration of heating and the optimum pressure when heating can be determined empirically in a few cases with a few experiments. The melting temperature of the thermoplastic used can serve as a guide. The higher it is

die Temperatur der Trennplatte 14 ist, desto kürzer muss die Anpresszeit und desto kleiner muss der Anpressdruck der Anpressplatten 13 ausgelegt werden, um nur die Oberfläche des Wickelguts zu erweichen. the temperature of the separating plate 14 is, the shorter the pressing time and the smaller the pressing pressure of the pressing plates 13 has to be designed in order to soften only the surface of the winding material.

Sobald die gewünschte Materialerweichung erfolgt ist, wird gemäss Fig. 4 die heisse Trennplatte 14 durch eine Hubeinrichtung 15 nach oben gefahren, so dass die Wickelkörper 2, 3 paarweise an den erhitzten Stirnflächen gegeneinander gepresst werden können. Dabei entstehen die oberflächlichen Schweiss-Stellen, die in Fig. 1a und 1b schematisch dargestellt sind. As soon as the desired material softening has taken place, the hot separating plate 14 is moved upwards by a lifting device 15, as shown in FIG. 4, so that the winding bodies 2, 3 can be pressed against one another in pairs on the heated end faces. This creates the superficial welding spots, which are shown schematically in FIGS. 1a and 1b.

Nach kurzem Abkühlen können die zusammen-geschweissten Anordnungen von je zwei Wickelkörpern 2, 3 aus der Vorrichtung 10 entnommen werden. Selbstverständlich kann die Entnahme und die Zufuhr automatisiert werden. After briefly cooling, the welded-together arrangements of two winding bodies 2, 3 each can be removed from the device 10. Of course, the removal and supply can be automated.

Fig. 5 zeigt ein abgewandeltes Ausführungsbeispiel, bei welchem vier Wickelkörper 2a, 2b, 2c und 2d zu einer Anordnung lösbar miteinander verbunden werden sollen. Bei der dargestellten Anordnung werden die Wickelkörper 2 aus Richtung des Pfeils Z zugeführt und in eine U-förmige Schiene 20 seitlich eingeschoben. Die eingebrachten Wickelkörper 2 können taktweise durch eine Anpressplatte 23 nach rechts gefördert und gegen die Trennplatte 14 bzw. die nächstfolgenden Wickelkörper 2 gepresst werden. Die Anpressplatte 23 wird durch eine Schubstange 24 mittels einer nicht dargestellten Antriebseinrichtung angetrieben, die in der Lagerung 22 vorgesehen ist. 5 shows a modified exemplary embodiment in which four winding bodies 2a, 2b, 2c and 2d are to be detachably connected to one another to form an arrangement. In the arrangement shown, the winding bodies 2 are fed from the direction of the arrow Z and are laterally inserted into a U-shaped rail 20. The introduced winding bodies 2 can be conveyed clockwise through a pressure plate 23 and pressed against the separating plate 14 or the next following winding bodies 2. The pressure plate 23 is driven by a push rod 24 by means of a drive device, not shown, which is provided in the bearing 22.

Von den in Fig. 5 dargestellten Wickelkörpern 2 sind bereits die Wickelkörper 2a und 2b miteinander verschweisst. Zwischen den Wickelkörpern 2b und 2c befindet sich die Trennplatte 14, durch welche die einander zugewandten Oberflächen der Wickelkörper 2c und 2b in der vorher beschriebenen Weise erhitzt werden. Durch eine zweite Anpresseinrichtung 25 mit einer zweiten Anpressplatte 23a werden die Wickelkörper 2a und 2d nach links gegen die Trennplatte 14 gepresst. Die Anpresseinrichtung 25 presst dabei die Anpressplatte 23a in x-Richtung nach links, während die Anpressplatte 23 nach rechts drückt. Sobald die Oberflächen der Wickelkörper 2c und 2b genügend erwärmt sind, wird die Trennplatte 14 durch die Hubeinrichtung 15 analog Fig. 4 zwischen den Wickelkörpern 2b und 2c herausgezogen, so dass diese durch die Anpressplatten 23a und 23 gegeneinander pressbar sind. Nach dem Abkühlen wird die Anpressplatte 23a in Richtung des Pfeils y aus der Bahn des Wickelkörpers 2a weggezogen,. so dass durch die Anpressplatte 23 die Anordnung von Wickelkörpern um einem Wickelkörper entsprechenden Vorschub-Schritt nach rechts verschoben werden kann. Sodann kann die Anpressplatte 23 zurückgezogen werden, so dass seitlich ein neuer Wickelkörper 2 zugeführt werden kann. Gleichzeitig wird die Trennplatte 14 an der neuen Trennstelle zwischen zwei Wickelkörpern eingefahren, die Anpressplatte 23 wird von rechts gegen die Stirnseite d=s vordersten Wickelkörpers 2a gefahren und der Verschweissvor-gang beginnt von neuem. The winding bodies 2a and 2b of the winding bodies 2 shown in FIG. 5 are already welded to one another. Between the winding bodies 2b and 2c there is the separating plate 14, by means of which the mutually facing surfaces of the winding bodies 2c and 2b are heated in the manner previously described. The bobbins 2a and 2d are pressed to the left against the separating plate 14 by a second pressing device 25 with a second pressing plate 23a. The pressing device 25 presses the pressing plate 23a to the left in the x direction, while the pressing plate 23 presses to the right. As soon as the surfaces of the winding bodies 2c and 2b are sufficiently heated, the separating plate 14 is pulled out between the winding bodies 2b and 2c by the lifting device 15 analogously to FIG. 4, so that these can be pressed against one another by the pressure plates 23a and 23. After cooling, the pressure plate 23a is pulled away from the path of the winding body 2a in the direction of the arrow y. so that the arrangement of winding bodies can be shifted to the right by a pressure step 23 corresponding to a winding step. The pressure plate 23 can then be withdrawn so that a new winding body 2 can be fed in laterally. At the same time, the separating plate 14 is moved in at the new separating point between two winding bodies, the pressure plate 23 is moved from the right against the end face d = s foremost winding body 2a and the welding process begins again.

Da die Anpresseinrichtung 25 durch einen Motor Since the pressing device 25 by a motor

26 auf einer schematisch angedeuteten Spindel 27 verfahrbar ist, lässt sich dadurch die Anpressplatte 23a an beliebige Konfigurationen von Wickelkörpern 2 anpassen und es können auch zwei, drei, vier oder mehrere Wickelkörper zu einer Anordnung verschweisst werden. 26 can be moved on a schematically indicated spindle 27, the pressure plate 23a can thereby be adapted to any configurations of winding bodies 2 and two, three, four or more winding bodies can also be welded to form an arrangement.
