Description

Die Erfindung betrifft eine Vorrichtung zum fadengerechten Abtrennen eines Abschnittes von einer Stoffbahn, mit einer ortsfesten Halteeinrichtung aus einem Tisch mit zugeordneten Klemmen für den Rand der zu zertrennenden Stoffbahn und mit einem angetriebenen Schlitten mit wenigstens einem Widerlager zum Aufreißen der Stoffbahn und zur Führung der voneinander getrennten Kanten einerseits des Abschnittes und andererseits der restlichen Stoffbahn.The invention relates to a device for thread-appropriate separation of a section of a fabric, with a stationary holding device from a table with associated clamps for the edge of the fabric to be separated and with a driven carriage with at least one abutment for tearing the fabric and for guiding the separated Edges on the one hand of the section and on the other hand of the rest of the 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 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 e.g. 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 for the section of fabric to be separated to be torn off from the rest of the fabric. The tearing takes place according to the thread, i.e. the tear edges are delimited by continuous threads.

Eine gattungsgemäße Vorrichtung ist auch in der GB-PS 93 58 (A.D. 1915) beschrieben. Hierbei wird mit einem Messer ein kleiner Einschnitt in der Stoffbahn gemacht. Nach Zurückziehen des Messers wird die Stoffbahn mit einem Widerlager aufgerissen, welches gleitend an den aufgerissenen Rändern der Stoffbahn entlanggeführt wird. Dabei können jedoch auch Fäden, die sich in Richtung der Reißkante erstrecken, zertrennt werden.A generic device is also described in GB-PS 93 58 (A.D. 1915). Here, a small incision is made in the fabric with a knife. After pulling back the knife, the fabric is torn open with an abutment, which is slid along the torn edges of the fabric. However, threads that extend in the direction of the tear edge can also be separated.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs beschriebenen Gattung so zu verbessern, daß das Abtrennen fadengerecht erfolgt.The object of the invention is to improve a device of the type described in the opening paragraph in such a way that the separation takes place according to the thread.

Diese Aufgabe wird gelöst mit einer Vorrichtung der eingangs beschriebenen Gattung, die gekennzeichnet ist durch zwei nebeneinander angeordnete Rollen als Widerlager, wobei die Rollen als Doppelkegelrollen (Diabolorollen) ausgebildet sind, deren kleinste Querschnitte mit der Tischoberfläche fluchten.This object is achieved with a device of the type described at the outset, which is characterized by two rollers arranged next to one another as abutments, the rollers being designed as double-tapered rollers (diabolo rollers), the smallest cross sections of which are aligned with the table surface.

Damit ist sichergestellt, daß die in Reißrichtung verlaufenden Fäden der Stoffbahn nicht aufgetrennt werden, sondern nur die quer zur Reißrichtung verlaufenden Fäden. Die Stoffbahn wird auf der Tischoberfläche geführt, und zwar durch die Doppelkegelrollen selbst, ohne daß zusätzliche Führungseinrichtungen erforderlich wären. Diese Führung ist unter allen Umständen wirksam, unabhängig davon, wie sich die Stoffbahn beidseits der Reißlinie bewegt. Es genügt, wenn sie am Beginn der Reißlinie festgehalten wird.This ensures that the threads of the fabric web running in the tearing direction are not separated, but only the threads running transverse to the tearing direction. The fabric is guided on the table surface by the double tapered rollers themselves, without the need for additional guide devices. This guidance is effective in all circumstances, regardless of how the fabric moves on both sides of the tear line. It is sufficient if it is held at the beginning of the tear line.

Der Schlitten ist vorzugsweise auf einer Bahn geführt, die sich im wesentlichen senkrecht zur Verbindungslinie der beiden Klemmen erstreckt. Die Klemmen können Klemmbacken aufweisen, 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 glattgelegt werden. Beim Einlegen der Stoffbahn in die Klemme 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. Beim Betätigen des bzw. der Hubzylinder liegt der Rand der Stoffbahn fest.The carriage is preferably guided on a path that extends essentially perpendicular to the connecting line of the two clamps. The clamps can have clamping jaws, one clamping jaw each being formed by a tab extending over the table surface and the other clamping jaw being formed by a movable plunger mounted in the table below the tab. The fabric can thus be spread out and smoothed out on the table. When the fabric web is inserted into the clamp, 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.

Der Schlitten ist vorzugsweise unterhalb der Tischoberfläche angeordnet und geführt, wobei die Rollen sich durch einen sich längs der Bahn des Schlittens erstreckenden Schlitz bis 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. 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 11-11 durch den Gegenstand nach Fig. 1;
  • Fig. 3 einen Schnitt in Richtung 111-111 durch den Gegenstand nach Fig. 1.
The carriage is preferably arranged and guided below the table surface, the rollers extending through a slot extending along the path of the carriage to above the table surface. 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. 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 11-11 through the object of Fig. 1.
  • 3 shows a section in the direction 111-111 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 attached to 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 Verbindungslinie 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 serves as a guide and drive for a carriage 15 which can be moved along the slot 3. 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 connecting 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 web 19 is cut into a short piece 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.
