Description

Die Erfindung betrifft eine Vorrichtung zum fadengerechten Abtrennen eines Abschnittes von einer Stoffbahn.The invention relates to a device for thread-appropriate separation of a section from a fabric.

Beim Zuschneiden von Stoffen, insbesondere gemusterten Stoffen, kommt es häufig darauf an, daß die Trennung längs bestimmter, durch das Muster vorgegebener Linien erfolgt, damit das spätere Zusammennähen verschiedener Zuschnitte mustergerecht erfolgen kann. Das gilt z.B. immer dann, wenn der Stoff ein Karomuster aufweist. Es gibt zwar Vorrichtungen, mit denen Abschnitte von einer Stoffbahn abgeschnitten werden können, dabei hängt die Schnittführung aber immer von der Führung der Stoffbahn oder von der Einspannung der Stoffbahn ab und ein mustergerechter Schnitt im obigen Sinne läßt sich kaum erreichen. In der Praxis ist es deswegen üblich, daß am Rand der Stoffbahn ein kleiner Einschnitt gemacht wird und daß dann der abzutrennende Stoffabschnitt von der restlichen Stoffbahn abgerissen wird. Das Reißen erfolgt fadengerecht, d.h. die Rißkanten werden von durchgehenden Fäden begrenzt.When cutting fabrics, in particular patterned fabrics, it is often important that the separation takes place along certain lines specified by the pattern, so that the subsequent sewing together of various cuts can be carried out according to the pattern. This applies, for example, whenever the fabric has a check pattern. There are devices with which sections can be cut off from a fabric web, but the cut always depends on the guidance of the fabric web or on the clamping of the fabric web and a pattern-like cut in the above sense can hardly be achieved. In practice, it is therefore usual for a small incision to be made at the edge of the fabric and then for the one to be cut off Section of fabric is torn from the remaining fabric. The tearing takes place according to the thread, ie the edges of the tear are delimited by continuous threads.

Aufgabe der Erfindung ist es, das fadengerechte Abtrennen zu mechanisieren.The object of the invention is to mechanize the thread-appropriate separation.

Diese Aufgabe wird gelöst mit einer Vorrichtung der eingangs beschriebenen Gattung, die gekennzeichnet ist, durch eine ortsfeste Halteeinrichtung für einen Rand, der zu zertrennenden Stoffbahn und durch einen angetriebenen Schlitten mit wenigstens einem Wiederlager" zum Aufreißen der Stoffbahn und zur Führung der voneinander getrennten Kan-ten einerseits des Abschnittes und andererseits der restlichen Stoffbahn.This object is achieved with a device of the type described at the outset, which is characterized by a stationary holding device for an edge, the web of material to be separated and by a driven carriage with at least one repository " for tearing open the web of material and for guiding the separated webs. on the one hand of the section and on the other hand of the remaining fabric.

Bei dieser Vorrichtung wird der eine Rand der Stoffbahn festgehalten und wird das Widerlager quer zur Stoffbahn bewegt, wobei es die Stoffbahn fadengerecht aufreißt und dadurch einen Abschnitt von der Stoffbahn trennt.In this device, one edge of the fabric is held and the abutment is moved transversely to the fabric, tearing open the fabric in line with the thread and thereby separating a section from the fabric.

Insbesondere kann die Halteeinrichtung zwei Klemmen aufweisen. Das Widerlager kann eine Rolle sein, wobei jedoch nach bevorzugter Ausführungsform der Erfindung zwei nebeneinander angeordnete Rollen als Widerlager vorgesehen sind. Der Schlitten wird vorzugsweise auf einer Bahn geführt, die sich im Wesentlichen senkrecht zur Verbindungslinie der beiden Klemmen erstreckt.In particular, the holding device can have two clamps. The abutment can be a roller, but according to a preferred embodiment of the invention, two rollers arranged next to one another are provided as abutments. The carriage is preferably guided on a path that extends essentially perpendicular to the connecting line of the two clamps.

Eine zu zertrennende Stoffbahn wird mit ihrem einen Rand in die Klemmen eingelegt und befestigt. Vorzugsweise sind die Klemmen an einem Tisch angeordnet, wobei jeweils eine Klemmbacke von einer sich über die Tischoberfläche erstreckenden Lasche und die andere Klemmbacke von einem unterhalb der Lasche im Tisch gelagerten beweglichen Stößel gebildet ist. Die Stoffbahn kann folglich auf dem Tisch ausgebreitet und glatt gelegt werden. Beim Einlegen der Stoffbahn in die Klemmen befindet sich der bewegliche Stößel außerhalb der Fläche, die von dem zu teilenden Stoff bedeckt wird. Zweckmäßig ist der bewegliche Stößel am Ende einer Kolbenstange eines pneumatisch oder hydraulisch betätigbaren Hubzylinders angeordnet, der betätigt wird, wenn die Stoffbahn zwischen die beiden Klemmbacken eingeführt ist. Bei dem Betätigen des bzw. der Hubzylinder liegt der Rand der Stoffbahn fest.A sheet of fabric to be cut is inserted with one edge into the clamps and fastened. The clamps are preferably arranged on a table, one clamp jaw each from a tab extending over the table surface and the other clamp jaw is formed by a movable plunger mounted below the bracket in the table. The fabric can therefore be spread out on the table and laid flat. When the fabric is inserted into the clamps, the movable plunger is outside the area covered by the fabric to be divided. The movable plunger is expediently arranged at the end of a piston rod of a pneumatically or hydraulically actuated lifting cylinder which is actuated when the fabric web is inserted between the two clamping jaws. When the lifting cylinder or cylinders are actuated, the edge of the fabric web is fixed.

Nunmehr wird der Rand der Stoffbahn zwischen den beiden Klemmen ein kurzes Stück eingeschnitten, so daß die Soll-Reißstelle mustegenau festgelegt ist und zudem die meist feste Webekante durchgetrennt ist und der Stößel nur das Weiterreißen zu besorgen hat. Der Schlitten ist vorzugsweise unterhalb der Tischoberfläche angeordnet und geführt, wobei die Rollen sich durch einen längs der Bahn des Schlittens erstreckenden Schlitz über die Tischoberfläche erstrecken. Der Antrieb des Schlittens kann ein pneumatisch oder hydraulisch betätigbarer Hubzylinder sein, der den Schlitten auch führt und dazu unterhalb des Schlitzes angeordnet ist. Bei Betätigung des Schlittenantriebs werden die beiden Rollen in Verlängerung des Einschnittes der Stoffbahn längs des Schlitzes geführt und reißen dabei die Stoffbahn fadengerecht auf.Now the edge of the fabric web is cut a short distance between the two clamps, so that the target tear point is set exactly to the pattern and, moreover, the mostly firm selvedge is severed and the plunger only has to take care of tearing. The slide is preferably arranged and guided below the table surface, the rollers extending over the table surface through a slot extending along the path of the slide. The drive of the carriage can be a pneumatically or hydraulically actuated lifting cylinder which also guides the carriage and is arranged below the slot for this purpose. When the carriage drive is actuated, the two rollers are guided along the slot as an extension of the incision in the fabric web and thereby tear the fabric web in line with the thread.

Zur besseren Führung der Kanten einerseits des Abschnittes und andererseits der restlichen Stoffbahn empfiehlt sich eine Ausführungsform, bei der die Rollen als Doppelkegelrollen (Diabolorollen) ausgebildet sind, deren kleinste Querschnitte mit der Tischoberfläche fluchten. Dadurch wird erreicht, daß die Stoffbahn jedenfalls im Bereich der Reißlinie von den Doppelkegelrollen unmittelbar auf der Tischoberfläche geführt wird.For better guidance of the edges on the one hand of the section and on the other hand of the rest of the fabric web, an embodiment is recommended in which the rollers are designed as double-tapered rollers (diabolo rollers), the smallest cross-sections of which are aligned with the table surface. This ensures that the fabric web is guided in the area of the tear line by the double tapered rollers directly on the table surface.

Im Folgenden wird ein in der Zeichnung dargestelltes Ausführungsbeispiel der Erfindung erläutert; es zeigen:

  • Fig. 1 eine Draufsicht auf eine Vorrichtung zum fadengerechten Abtrennen eines Abschnitts von einer Stoffbahn;
  • Fig. 2 einen Schnitt in Richtung II-II durch den Gegenstand nach Fig. 1;
  • Fig. 3 einen Schnitt in Richtung III-III durch den Gegenstand nach Fig. 1.
An exemplary embodiment of the invention illustrated in the drawing is explained below; show it:
  • Figure 1 is a plan view of a device for thread-appropriate separation of a section from a fabric.
  • Figure 2 is a section in the direction II-II through the object of Fig. 1.
  • 3 shows a section in the direction III-III through the object according to FIG. 1.

Die dargestellte Vorrichtung besteht in ihrem grundsätzlichen Aufbau aus einem kastenförmigen Tisch 1, dessen obere Wandung 2 einen sich über die gesamte Länge des Tisches erstreckenden Schlitz 3 aufweist. An einem Ende des Tisches und beidseits des Schlitzes 3 sind auf der Oberseite des Tisches Laschen 4, 5 befestigt, deren in Richtung des Schlitzes 3 vorstehende Enden mit der Oberseite des Tisches 1 jeweils einen Einführungsspalt definieren. Unter den vorstehenden Enden der Laschen 4, 5 befinden sich in der oberen Wandung 2 des Tisches 1 öffnungen, in denen bewegliche Stößel 7, 8 angeordnet sind. Die Stößel sitzen an den Enden von Kolbenstangen 9,10 von pneumatisch betätigbaren Hubzylindern 11,12 die am Boden 13 des kastenförmigen Tisches befestigt sind. Dementsprechend können die Stößel 7, 8 bei Betätigung der Hubzylinder 11,12 gegen die vorstehenden Enden der Laschen 4, 5 bewegt werden. Die vorstehenden Enden der Laschen 4, 5 und die Stößel 7, 8 bilden damit Klemmbacken von Klemmen.The device shown consists in its basic structure of a box-shaped table 1, the upper wall 2 of which has a slot 3 extending over the entire length of the table. At one end of the table and on both sides of the slot 3, tabs 4, 5 are fastened on the top of the table, the ends of which protrude in the direction of the slot 3 define an insertion gap with the top of the table 1. Under the projecting ends of the tabs 4, 5 there are openings in the upper wall 2 of the table 1, in which movable plungers 7, 8 are arranged. The plungers sit at the ends of piston rods 9, 10 of pneumatically actuated lifting cylinders 11, 12, which are fastened to the bottom 13 of the box-shaped table. Accordingly, the plungers 7, 8 can be moved against the projecting ends of the tabs 4, 5 when the lifting cylinders 11, 12 are actuated. The protruding ends of the tabs 4, 5 and the plungers 7, 8 thus form jaws of clamps.

Unter dem Schlitz 3 ist am Boden 13 des Tisches 1 ein weiterer Hubzylinder 14 befestigt, der sich über die gesamte Länge des Tisches 1 erstreckt und der als Führung und Antrieb für einen längs des Schlitzes 3 verfahrbaren Schlitten 15 dient. Der Schlitten 15 trägt an seiner Oberseite zwei Rollen 16, 17, die als Doppelkegelrollen (Diabolorollen) ausgebildet sind. Die Rollen 16, 17 sind so angeordnet, daß sich die Verbindunslinie ihrer Achsen senkrecht zur Richtung des Schlitzes 3 erstreckt und daß ihre kleinsten Querschnitte etwa in Höhe der Tischoberfläche angeordnet sind. Im übrigen sind die Rollen 16, 17 frei drehbar auf dem Schlitten 15 gelagert.Under the slot 3, a further lifting cylinder 14 is attached to the bottom 13 of the table 1, which extends over the entire length of the table 1 and which as Guidance and drive for a carriage 15 movable along the slot 3 is used. The carriage 15 carries on its top two rollers 16, 17 which are designed as double tapered rollers (diabolo rollers). The rollers 16, 17 are arranged so that the connection line of their axes extends perpendicular to the direction of the slot 3 and that their smallest cross sections are arranged approximately at the level of the table surface. Otherwise, the rollers 16, 17 are freely rotatable on the carriage 15.

Die Hubzylinder 11, 12 und 14 können in geeigneter Weise angesteuert werden. Eine Steuereinrichtung ist nicht dargestellt.The lifting cylinders 11, 12 and 14 can be controlled in a suitable manner. A control device is not shown.

Zum Abtrennen eines Abschnittes 18 von einer Stoffbahn 19 geht man wie folgt vor:

  • Der Rand der Stoffbahn 19 wird in die Einführungsspalte 6 zwischen vorstehenden Enden der Laschen 4, 5 und Stößeln 7, 8 eingeführt. Dann werden die Hubzylinder 11, 12 betätigt, so daß der Rand der Stoffbahn 19 festgeklemmt ist. Dabei befindet sich der Schlitten 15 mit den Rollen 16, 17 im Bereich der Klemmen. Vor oder nach dem Einspannen wird der Rand der Stoffbahn 19 ein kurzes Stück eingeschnitten, so daß sich die Ränder des Einschnittes an oder um die Rollen 16, 17 legen können. Nach Betätigung des Hubzylinders 14 wird der Schlitten 15 mit den Rollen 16, 17 von den Klemmen weg längs des Schlitzes 3 bewegt. Dabei wird die Stoffbahn fadengerade aufgerissen. Die Reißkanten werden an den engsten Querschnitten der Rollen 16, 17 unmittelbar auf der Tischoberfläche geführt. Nachdem der Abschnitt 18 auf diese Weise von der Stoffbahn 19 abgerissen worden ist, werden die Klemmen durch Betätigung der Hubzylinder 11, 12 gelöst und wird der Schlitten 15 wieder in seine Ausgangslage zurückgebracht.
To separate a section 18 from a fabric web 19, proceed as follows:
  • The edge of the fabric web 19 is inserted into the insertion gap 6 between the projecting ends of the tabs 4, 5 and plungers 7, 8. Then the lifting cylinders 11, 12 are actuated so that the edge of the fabric web 19 is clamped. The carriage 15 with the rollers 16, 17 is located in the area of the clamps. Before or after clamping, the edge of the fabric sheet 19 is cut a short distance so that the edges of the cut can lie on or around the rollers 16, 17. After actuation of the lifting cylinder 14, the carriage 15 with the rollers 16, 17 is moved away from the clamps along the slot 3. The fabric is torn straight. The tear edges are guided on the narrowest cross sections of the rollers 16, 17 directly on the table surface. After section 18 has been torn off in this way from the fabric web 19, the clamps are released by actuating the lifting cylinders 11, 12 and the carriage 15 is returned to its starting position.
