Description

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Öffnen von Textilfaserballen, bei dem ein in die Ballenoberflächenschicht eindringendes Faserabtragelement zum Abtragen von Faserflocken mit einer vorgegebenen Verschiebegeschwindigkeit über einer Reihe von Faserballen hin und her fahrbar ist und bei dem die Oberflächenschicht vor dem Abtragen durch ein vor dem Faserabtragelement, in Verschieberichtung gesehen, vorgesehenen Verdichtungsmittel verdichtet wird.The invention relates to a method and a device for opening textile fiber bales, in which a fiber removal element penetrating into the bale surface layer for removing fiber flakes can be moved back and forth over a row of fiber bales at a predetermined displacement speed, and in which the surface layer passes through before removal a compression means provided in front of the fiber removal element, viewed in the direction of displacement, is compressed.

Aus der Praxis ist eine Ballenabtragmaschine Marke »Unifloc« des Anmelders gemäß Oberbegriff der Patentansprüche 1 und 2 bekannt.A “Unifloc” brand bale removal machine from the applicant is known in practice according to the preamble of claims 1 and 2.

Bekannterweise werden die Ballen in einer Reihe auf eine Bodenfläche gelegt, um mit dem Abtragelement an der oberen Fläche der Ballen Flocken herauszulösen, welche pneumatisch weitergefördert werden.As is known, the bales are placed in a row on a floor surface in order to use the removal element on the upper surface of the bale to remove flakes which are conveyed on pneumatically.

Je nach Bodenbeschaffenheit und Rauheit der Bodenfläche wirkt sich das an sich vorteilhafte Verdichtungsmittel bei der Restabtragung der Faserballen insofern nachteilig aus, als Resten niedriger Höhen, z. B. 10 cm und weniger, von dem Verdichtungsmittel nicht eindeutig erfaßt und dadurch vor dem Faserabtragelement hergeschoben werden können.Depending on the nature of the soil and the roughness of the floor surface, the compacting agent, which is advantageous per se, has a disadvantageous effect on the residual removal of the fiber bales in that residues of low heights, e.g. B. 10 cm and less, not clearly detected by the compression means and can be pushed in front of the fiber ablation element.

Diesen Nachteil zu beheben ist Aufgabe der Erfindung.The object of the invention is to remedy this disadvantage.

Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe verfahrensmäßig dadurch, daß im Bereich der Verdichtung die Oberflächenschicht in Richtung Faserabtragelement gefördert wird.The invention, as characterized in the claims, achieves the object procedurally in that the surface layer is promoted in the direction of the fiber removal element in the area of compression.

Durch diesen erfinderischen Schritt entstand nicht nur der Vorteil, daß auch die Ballenreste dem Abtragorgan zugefördert wurden sondern auch noch, daß die Verdichtung veränderbar gestaltet werden kann.This inventive step not only gave the advantage that the remains of the bale were also conveyed to the removal member, but also that the compaction can be made changeable.

Vorrichtungsmäßig wurde die Aufgabe durch die Merkmale gelöst, wie sie im kennzeichnenden Teil des Anspruches 2 angegeben sind.In terms of the device, the object was achieved by the features as specified in the characterizing part of claim 2.

Dadurch wird vorteilhafterweise das Fasermaterial an einer Stelle vom Fördermittel erfaßt, an der ein Ausbrechen aus dem Oberflächenverband verhindert und dadurch positiver als ohne diese Maßnahme gefördert wird.As a result, the fiber material is advantageously gripped by the conveying means at a point at which a break-out from the surface structure is prevented and is thereby conveyed more positively than without this measure.

Die weiteren vorteilhaften Ausführungsformen des erfindungsgemäßen Verfahrens, respektive der Vorrichtung, sind in den weiteren Ansprüchen enthalten.The further advantageous embodiments of the method according to the invention or the device are contained in the further claims.

Auf den Wellen 24 und 25 sitzen in bestimmten Abständen verteilt sternförmige Förderscheiben 28, die durch in den Wänden 15 vorgesehene schlitzförmige Öffnungen 29 in die zu verdichtende Faserballenoberflächenschicht hineinragen. Die Förderscheiben 28 sind, wie in Fig. 1 gezeigt, durch zwei aneinander geheftete gleichseitige Dreiecke gebildet. Die Lager 26 und 26' sowie die Lager 27 und 27' sind, wie in Fig. 3 für die Lager 27 und 27' gezeigt, mit Schlitzen 30 als Führungsschlitze für die Schrauben 31 (Fig. 2) versehen. Zur Aufnahme der Schrauben 31 sind je im Maschinenrahmen 2 und in der Frontwand 6 Gewindelöcher (nicht gezeigt) vorgesehen. Dadurch sind die Sternwalzen 22 und 23 in den mit dem Pfeil A (Fig. 1 und 3) gezeigten Richtungen verschiebbar angeordnet. In der Frontwand 6 und im Maschinenrahmen 2 sind Schlitze (nicht gezeigt) eingelassen, um den Wellen 24 und 25 die entsprechende Bewegung zu erlauben.Furthermore, the removal member each comprises a star roller 22 and 23, (only partially shown in Fig. 2) which by means of a shaft 24 and. 25 in bearings 26 and 26 'respectively. 27 and 27 'are rotatably arranged.
