Abstract

Damit beim Restabtrag von Faserballen (14), d.h. beim Abtrag ab einer Resthöhe der Faserballen von z.B. 10 cm und weniger, die Resten nicht vor der Abtragmaschine hergeschoben werden, dient, falls der Restabtrag z.B. in einer Verschieberichtung V1 geschieht, eine Sternwalze 22 der positiven Förderung der sich unter einer schrägen Wand (15) befindlichen Ballenoberflächen-schicht. Die Förderung geschieht in Richtung einer Faserabtragwalze (8). Auf der gegenüberliegenden Seite der Faserabtragwalze (8) dreht eine Sternwalze (23) in derselben Richtung und mit derselben Umfangsgeschwindigkeit wie die Sternwalze (22). Dadurch entsteht relativ zur Faserabtragwalze (8) eine negative Förderung der Faserballenoberflächenschicht. Diese negative Förderung verhindert im wesentlichen, dass einzelne Faserballenreste nicht durch Hängenbleiben mitgerissen, sondern nach rückwärts gefördert werden.So that during the residual removal of fiber bales (14), i.e. when removing from a residual height of the fiber bale e.g. 10 cm and less, the residues are not pushed in front of the removal machine, is used if the residual removal e.g. in a displacement direction V1, a star roller 22 positively promotes the bale surface layer located under an inclined wall (15). The promotion takes place in the direction of a fiber removal roller (8). On the opposite side of the fiber removal roller (8), a star roller (23) rotates in the same direction and at the same peripheral speed as the star roller (22). This results in a negative conveyance of the fiber bale surface layer relative to the fiber removal roller (8). This negative funding essentially prevents individual fiber bale residues not being carried away by getting caught, but being conveyed backwards.

Description

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Oeffnen 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 an apparatus 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 Patentansprü--che 1 und 4 bekannt.A "Unifloc" bale removal machine from the applicant according to the preamble of claims 1 and 4 is known in practice.

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 floor 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, for example 10 cm and less, cannot be clearly detected by the compacting agent and can therefore be pushed in front of the fiber removal 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.In terms of the method, the invention, as characterized in the claims, achieves the object in that the surface layer is conveyed in the direction of the compression in the direction of the fiber removal element.

Durch diesen erfinderischen Schritt entstand nicht nur der Vorteil, dass auch die Ballenresten 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 dadurch gelöst, dass im Bereich des Verdichtungsmittels ein in die Ballenoberflächenschicht mit einer gegebenen Eintauchtiefe greifendes Fördermittel angeordnet ist.In terms of the device, the object was achieved in that a conveying means, which reaches into the bale surface layer with a given immersion depth, is arranged in the region of the compacting means.

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 grasped 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.

Im folgenden wird die Erfindung anhand illustrierter Ausführungsbeispiele näher erläutert.The invention is explained in more detail below on the basis of illustrated exemplary embodiments.

Eine Welle 7 einer Faserabtragwalze 8 ist einerseits in einem am Maschinenrahmen 2 befestigten Lager 9 und in einem an der Frontwand 6 befestigten Lager 10 drehbar gelagert. Auf der Welle 7 sind Zahnscheiben 11 (Zähne mit strichpunktierter Linie nur angedeutet) schräg, d.h. als Taumelscheiben fest angeordnet. Die Zahnscheiben sind für den Faserflockenabtrag in beiden Drehrichtungen der Zahnscheiben geeignet und ragen durch Oeffnungen 12 eines Rostes 13 in Faserballenoberflächenschichten von Faserballen 14. Der Rost 13 ist einerseits am Maschinenrahmen 2 und anderseits an der Frontwand 6 befestigt. Beidseits des Rostes 13 ist je eine Wand 15 mittels damit verbundenen Scharnieren 16 schwenkbar angeordnet. Die Achsen der Scharniere 16 sind je einerseits in der Frontwand 6 und im Maschinenrahmen 2 fest eingelassen. Die Fixierung der Wände 15 innerhalb eines Schwenkbereichesd von 10-30 Winkelgraden geschieht durch je eine Lasche 18 und 19, die mittels Fixierschrauben 20 gegeneinander gepresst werden. Als Basis des Schwenkbereiches kann angenommen werden, dass bei 0 Winkelgraden die Wände 15 parallel zur Bodenfläche 17 wären.A shaft 7 of a fiber removal roller 8 is rotatably supported on the one hand in a bearing 9 fastened to the machine frame 2 and in a bearing 10 fastened to the front wall 6.

The walls 15 are fixed within a swiveling range d of 10-30 degrees of angle by a tab 18 and 19, which are pressed against each other by means of fixing screws 20. The basis of the swivel range can be assumed that at 0 degrees of angle, the walls 15 would be parallel to the floor surface 17.

Die Laschen 19 sind Teile der Wände 4 resp. 5 und die Laschen 18 sind Teile der Wände 15. Die Laschen 18 und 19 sind derart mit dem gleichen Radius konvex, resp. konkav gewölbt, dass sie bei der Schwenkbewegung aneinander gleiten.The tabs 19 are parts of the walls 4, respectively. 5 and the tabs 18 are parts of the walls 15. The tabs 18 and 19 are convex with the same radius, respectively. concave so that they slide against each other when swiveling.

Ausserdem sind die Laschen 18 zur Aufnahme der Fixierschrauben 20 mit Gewindelöchern (nicht gezeigt) versehen.

In order to allow the pivoting movement of the walls 15, on the other hand, the tabs 19 are per fixing screw 20 provided with a slot 21 (Fig. 4).

Im weiteren umfasst das Abtragorgan je eine Sternwalze 22 und 23, (in Fig. 2 nur teilweise gezeigt) welche mittels einer Welle 24 resp. 25 in Lagern 26 und 26' resp. 27 und 27' drehbar angeordnet sind. Auf den Wellen 24 und 25 sitzen in bestimmten Abständen verteilt sternförmige Förderscheiben 28, die durch in den Wänden 15 vorgesehene schlitzförmige Oeffnungen 29 in die zu verdichtende Faserballenoberflächenschicht hineinragen. Die Förderscheiben 28 sind, wie in Figur 1 gezeigt, durch zwei aneinander geheftete gleichseitige Dreiecke gebildet. Die Lager 26 und 26' sowie die Lager 27 und 27' sind, wie in Figur 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. At certain intervals, star-shaped conveyor disks 28 sit on the shafts 24 and 25 and protrude into the fiber bale surface layer to be compressed through slot-shaped openings 29 provided in the walls 15. The conveyor disks 28, as shown in FIG. 1, are formed by two equilateral triangles tacked together. The bearings 26 and 26 'and the bearings 27 and 27' are, as shown in FIG. 3 for the bearings 27 and 27 ', provided with slots 30 as guide slots for the screws 31 (FIG. 2). To accommodate the screws 31, 6 threaded holes (not shown) are provided in the machine frame 2 and in the front wall. As a result, the star rollers 22 and 23 are arranged displaceably in the directions shown by the arrow A (FIGS. 1 and 3). Slits (not shown) are made in the front wall 6 and in the machine frame 2 in order to allow the shafts 24 and 25 to move accordingly.
