Description
Vorrichtung zum Niederdrücken der Stoffbahnen bei Zuschneidemaschinen Die bei Zuschneidemaschinen bisher verwendeten Vorrichtungen zum Niederdrücken der Stoffbahnen haben den Nachteil, daß die zum Niederdrücken der Preßrolle dienende Feder zufolge ihrer ungünstigen Anordnung sehr stark beansprucht ist, was ein vorzeitiges Zugrundegehen zur Folge hat. Dabei sichert die Feder nicht die entsprechende feste Lage der Preßrollen während der Bewegung der Maschine. Demgegenüber ist nach der Erfindung die Vorrichtung derart ausgebildet, daß am Maschinenständer ein auf- und abwärts bewegbarer und mittels einer Schraube feststellbarer Block befestigt und auf diesem der die Preßrollen tragende Tragarm angelenkt ist, welcher ein bügelartiger, zweiarmiger Hebel ist und unter der Spannkraft einer Feder steht. Durch diese Ausbildung wird erreicht, daß zum Niederdrücken bedeutend weniger Spannkraft erforderlich ist, da die Feder ihre Wirkung auf einen Hebelarm ausübt, daß ferner die auf einem Hebelarm sitzenden und nicht senkrecht abwärts gedrückten Rollen eine vollkommen feste Lage besitzen.Device for pressing down the fabric webs in cutting machines The devices for pressing down the previously used in cutting machines Fabric webs have the disadvantage that they are used to depress the press roller As a result of its unfavorable arrangement, the spring is very stressed, which is premature Has the consequence. The spring does not secure the corresponding firm Position of the press rollers while the machine is moving. In contrast, according to the Invention, the device is designed such that on the machine stand and up downwardly movable and lockable by means of a screw block attached and on this the support arm carrying the pressure rollers is articulated, which is a bracket-like, is a two-armed lever and is under the tension of a spring. Through this training it is achieved that significantly less clamping force is required to press down, since the spring exerts its effect on a lever arm, that furthermore that on a lever arm seated and not vertically pushed down rolls a completely fixed position own.
Auf der Zeichnung ist eine Ausführungsform des Gegenstandes der Erfindung beispielsweise dargestellt, und zwar ist: Abb. r eine Seitenansicht der Zuschneidemaschine, Abb.2 ein senkrechter Schnitt und eine teilweise Ansicht eines Teiles der Maschine in größerem Maßstab, Abb. 3 ein Schnitt nach der Linie A-B der Abb. 2, Abb. q. ein Schnitt nach der Linie C-D der Abb. 2, Abb. 5 ein Schnitt nach der Linie E-F der Abb. 2.In the drawing is an embodiment of the subject matter of the invention shown for example, namely: Fig.r a side view of the cutting machine, Fig.2 is a vertical section and a partial view of part of the machine on a larger scale, Fig. 3 a section along the line A-B in Fig. 2, Fig. q. a Section along the line C-D of Fig. 2, Fig. 5 a section along the line E-F of Fig. 2.
Am Maschinenständer a ist über dem Fuß t ein auf und ab schiebbarer Block 2 mittels einer Schraube 3 befestigt. Diesen Block umgibt beiderseits ein Bügel q., welcher mittels der Zapfen 5 an den Block 2 angelenkt ist. Das rückwärtige Ende des Bügels ist mittels einer Feder 6 mit einem nach oben ragenden Ansatz 7 des Blockes 2 verbunden. Die vorderen Enden der Bügelschenkel tragen die das Messer p von zwei Seiten umfassenden geriffelten Preßrollen B.On the machine stand a there is an up and down slide above the foot t Block 2 fastened by means of a screw 3. This block is surrounded on both sides by a Bracket q., Which is hinged to the block 2 by means of the pin 5. The rear The end of the bracket is secured by a spring 6 with an upwardly projecting extension 7 of block 2 connected. The front ends of the bow legs carry the knife p grooved press rollers B encircling two sides.
Die Maschine arbeitet in folgender Weise: Der Gleitblock :2 wird in eine Stellung gebracht, bei welcher die Stoffe zwischen dem Fuß t und den Preßrollen 8 Platz haben, so daß die auf einmal zuzuschneidenden Stoffe auf die obere gewölbte Seite des Fußes gelegt werden. Nachdem die Feder 6 das rückwärtige Ende des Bügels .l. aufwärts zieht, liegen die Preßrollen 8 auf dem unter ihnen befindlichen Stoffstapel auf und pressen die Stoffe aneinander. Das Messer zerschneidet während seiner Abwärtsbewegung den Stoffstapel und dringt in den Fuß t ein, während es sich bei seiner Aufwärtsbewegung über den Stoffstapel hebt. Die Aufgabe der Preßrollen 8 ist, den Stoffstapel zusammenzuhalten und zu verhindern, daß das Messer während seines Aufwärtsganges den Stoff mit nach oben nimmt.The machine works in the following way: The sliding block: 2 is in brought a position in which the fabrics between the foot t and the press rollers 8 space so that the fabrics to be cut at once are arched on the top Side of the foot. After the spring 6 the rear end of the bracket .l. pulls upwards, the press rollers 8 lie on the pile of fabric below them and press the fabrics together. The knife cuts as it moves downwards the pile of fabric and penetrates the foot t as it moves upward lifts over the pile of fabric. The task of the pressure rollers 8 is to hold the pile of fabric together and to prevent the knife from dragging the fabric with it during its upward movement above takes.
