Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Trennen eines Faserbandes, wie dies im Oberbegriff des ersten Anspruches beschrieben ist.The invention relates to a device for cutting a sliver, as described in the preamble of the first claim.

Aus der US-Patentschrift Nr. 3605198 ist eine Vorrichtung zum automatischen Wechseln von Kannen bekannt, bei der ein Faserband durch einen schwenkbaren Doppelarm festgehalten und mittels einer Schwenkbewegung zweier Hebel in einer Richtung quer zum Faserband getrennt wird.From US Pat. No. 3605198 a device for automatically changing cans is known, in which a sliver is held by a pivotable double arm and separated by means of a pivoting movement of two levers in a direction transverse to the sliver.

Die Nachteile dieser Vorrichtung liegen einerseits in einem umfangreichen notwendigen Mechanismus, sowie in der Notwendigkeit des vollzogenen Kannenwechsels bevor das Band getrennt werden kann.The disadvantages of this device lie on the one hand in an extensive mechanism required, and in the need to change the can before the belt can be separated.

Eine weitere US-PS Nr. 3354513 zeigt eine durch ein Kraftmittel automatisch betätigbare Schere, welche ein zwischen Bandkanalausgang und verschobener voller Kanne durchhängendes Band trennt.Another US Pat. No. 3354513 shows a pair of scissors that can be actuated automatically by a power means and that separates a band sagging between the band channel outlet and the displaced full can.

Es können dieselben Nachteile wie für die Vorrichtung der US-PS 3605198 aufgeführt werden.The same disadvantages as for the device of US-PS 3605198 can be listed.

Eine dritte US-Patentschrift mit Nummer 3381342 zeigt und beschreibt schliesslich eine Faserbandtrennvorrichtung, bei der nach vollzogenem Kannenwechsel das Faserband von einem pneumatisch verschiebbaren Greifer erfasst und gegen ein in Gegenrichtung bewegbares Trennmittel gebracht wird. Das Trennmittel wird dabei vom Greifer betätigt.A third US patent number 3381342 finally shows and describes a sliver separating device in which, after the can has been changed, the sliver is gripped by a pneumatically displaceable gripper and brought against a separating means which can be moved in the opposite direction. The release agent is actuated by the gripper.

Auch für diese Vorrichtung gelten die für die US-PS 3605198 erwähnten Nachteile.The disadvantages mentioned for US Pat. No. 3,505,198 also apply to this device.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu beheben und eine einfache Bandtrennvorrichtung vorzuschlagen, welche gleichzeitig mit dem Kannenwechsel betätigbar ist.The invention has for its object to remedy these disadvantages and to propose a simple tape cutting device which can be operated simultaneously with the can change.

Diese Aufgabe wird durch die in den Ansprüchen aufgeführte Erfindung gelöst.This object is achieved by the invention set out in the claims.

Die Vorteile der Erfindung sind im wesentlichen darin zu sehen, dass die Bandtrennung gleichzeitig mit dem Wechsel einer vollen Kanne gegen eine leere Kanne durchgeführt werden kann, und dass die Vorrichtung strukturell und funktionell einfach aufgebaut ist.The advantages of the invention can be seen essentially in the fact that the band separation can be carried out simultaneously with the change of a full can against an empty can, and that the device is structurally and functionally simple.

Die Erfindung wird im folgenden anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert.The invention is explained in more detail below with the aid of drawings illustrating only one embodiment.

Es zeigt:

  • Fig. 1 und 3 je einen Aufriss eines Teiles einer Kannenwech-selvorrichtung mit einer Kannenfüllstation und einer Kannenausfahrvorrichtung sowie mit einer erfindungsgemässen Vorrichtung, halbschematisch dargestellt,
  • Fig. 2 je eine Draufsicht der Vorrichtung von Fig. 1 und 4 resp. 3, halbschematisch dargestellt.
It shows:
  • 1 and 3 each show an elevation of a part of a can changing device with a can filling station and a can extending device and with one device according to the invention, shown semi-schematically,
  • Fig. 2 each a top view of the device of Fig. 1 and 4 respectively. 3, shown semi-schematically.

In einer Kannenfüllstation mit einem Bodenteil 1 und einem Kopfteil 2 (in Fig. 2 mit strichpunktierten Linien angedeutet) ist ein Trichterrad 3 (in Fig. 1 und 2 mit strichlierten Linien angedeutet) im Kopfteil 2 rotierbar gelagert.In a can filling station with a base part 1 and a head part 2 (indicated by dash-dotted lines in FIG. 2), a funnel wheel 3 (indicated by dotted lines in FIGS. 1 and 2) is rotatably mounted in the head part 2.

Das Trichterrad dient zur Aufnahme eines Faserbandkanals 4 (mit strichlierten Linien angedeutet), der eine Faserbandausgangöffnung 5 aufweist.The funnel wheel serves to receive a sliver channel 4 (indicated by dashed lines), which has a sliver outlet opening 5.

Auf dem Bodenteil 1 steht eine zu füllende Kanne 6 in Fig. 1 (mit strichpunktierten Linien dargestellt).On the bottom part 1 there is a can 6 to be filled in FIG. 1 (shown with dash-dotted lines).

Eine Kannenausfahrvorrichtung 7 besteht aus einem Fahrgestell 8, einem daran schwenkbar angeordneten Arm 9 sowie einem daran schwenkbar angeordneten Kannenmitnehmer 10.A can extending device 7 consists of a chassis 8, an arm 9 pivotally arranged thereon and a can carrier 10 pivotally arranged thereon.

Das Fahrgestell 8 ist mittels daran angeordneten Laufrollen 11, 12 und 13 auf Schienen 14 und 15 fahrbar abgestützt. Die Schienen 14 und 15 sind ein Bestandteil der Kannenfüllstation.The chassis 8 is movably supported on rails 14 and 15 by means of rollers 11, 12 and 13 arranged thereon. The rails 14 and 15 are part of the can filling station.

Das Schwenken des Armes 9 respektive des Mitnehmers 10 geschieht mittels doppelt wirkendem Pneumatikzylinder 16, der einerseits mit dem Mitnehmer 10 direkt und anderseits mit dem Arm 9 über ein Federglied 17 je schwenkbar verbunden ist.The arm 9 or the driver 10 is pivoted by means of a double-acting pneumatic cylinder 16, which is pivotally connected on the one hand to the driver 10 and on the other hand to the arm 9 via a spring member 17.

Das Federglied 17 umfasst eine auf Zug und Druck beanspruchbare Schraubenfeder 18, welche in einer Büchse 19 gegen seitliches Ausscheren derart geführt ist, dass die Federwindungen gleitbar an der Innenwand der Büchse 19 geführt sind. Die Büchse 19 ist mit einer Kolbenstange des Zylinders 16 verbunden. Das eine Ende der Feder 18 ist mit dem Büchsenboden 21 fest und das andere Ende mittels Gelenkbolzen 22 mit dem Arm 9 gelenkig verbunden.The spring member 17 comprises a helical spring 18 which can be subjected to tensile and compressive stress and which is guided in a bush 19 against lateral swerving in such a way that the spring windings are slidably guided on the inner wall of the bush 19. The sleeve 19 is connected to a piston rod of the cylinder 16. One end of the spring 18 is fixed to the sleeve base 21 and the other end is articulated to the arm 9 by means of articulated bolts 22.

Der Arm 9 dient zur Aufnahme eines Bandabstreifers 23, der aus einem Halter 24 und einer mit diesem fest verbundenen Streiflippe 25 aus Kunststoff, z.B. Polyurethan besteht. Eine am Halter 24 vorgesehene Lasche 26 dient zusammen mit einem Gelenkbolzen 27 der gelenkigen Verbindung des Bandabstreifers 23 mit dem Arm 9. Diese Schwenkbarkeit ist lediglich notwendig, um dem Bandabstreifer 23 eine genaue Anlage an die mit der Trichterradunterseite 28 bündige Unterseite 29 des Kopfteiles 2 zu ermöglichen.The arm 9 serves to receive a belt scraper 23, which consists of a holder 24 and a sealing lip 25 made of plastic, e.g. Polyurethane is made. A bracket 26 provided on the holder 24, together with a hinge pin 27, serves for the articulated connection of the belt scraper 23 to the arm 9. This pivotability is only necessary in order for the belt scraper 23 to be in precise contact with the underside 29 of the head part 2, which is flush with the funnel wheel underside 28 enable.

Die Reibung zwischen Gelenkbolzen 27 und Lasche 26 resp. Arm 9 ist derart, dass sich die Lage des Bandabstreifers 23, relativ zum Arm 9, beim Schwenken aus der in Figur 1 und 2 gezeigten Arbeitsposition in eine im wesentlichen vertikale Ausgangsposition (nicht gezeigt) nicht verändert.The friction between hinge pin 27 and bracket 26, respectively. Arm 9 is such that the position of the belt scraper 23, relative to the arm 9, does not change when pivoting from the working position shown in FIGS. 1 and 2 into a substantially vertical starting position (not shown).

Das Trennen eines Faserbandes geschieht nun folgendermassen:

  • Nachdem eine Kanne 6 die gewünschte Füllhöhe erreicht hat wird der Pneumatikzylinder 16 derart betätigt, dass sich der Mitnehmer 10 und der Arm 9 aus der genannten Ausgangsposition in die in der Figur 1 resp. 2 gezeigte Arbeitsposition bewegen. In dieser Position liegt die Streiflippe 25 an der Unterseite 29 des Kopfteiles 2 an.
A sliver is now cut as follows:
  • After a can 6 has reached the desired filling level, the pneumatic cylinder 16 is actuated in such a way that the driver 10 and the arm 9 move from the stated starting position into the position shown in FIG. 2 work shown move position. In this position, the streak lip 25 rests on the underside 29 of the head part 2.

Anschliessend wird das Fahrgestell 8 der Kannenausfahrvorrichtung in Pfeilrichtung A verschoben, so dass der Mitnehmer 10 zur Anlage an die volle Kanne 6 gelangt und diese in der vorgenannten Pfeilrichtung A aus der Kannenfüllstation wegverschiebt. In der Folge erfasst die Streiflippe 25 das inzwischen stillgesetzte Faserband an der Ausgangsöffnung 5 des Faserbandkanales 4 und zerreisst das Faserband mittels dieser Streifbewegung innerhalb einer Vorschublänge B, welche im Minimum der doppelten Länge der längsten im Band enthaltenen Faser entspricht. Die minimale Kannenausfahrstrecke muss deshalb derart gewählt werden, dass diese Bedingung erfüllt ist.Subsequently, the chassis 8 of the can extending device is moved in the direction of arrow A, so that the driver 10 comes to rest against the full can 6 and moves it away from the can filling station in the aforementioned arrow direction A. As a result, the wiping lip 25 detects the fiber sliver which has meanwhile stopped at the exit opening 5 of the sliver channel 4 and tears the fiber sliver by means of this wiping movement within a feed length B which corresponds to at least twice the length of the longest fiber contained in the sliver. The minimum can extension distance must therefore be selected so that this condition is met.

Nachdem die volle Kanne ihre nächste Funktionsposition ausserhalb der Kannenfüllstation erreicht hat, wird der Pneumatikzylinder 16 erneut betätigt, so dass der Mitnehmer 10 sowie der Arm 9 zurück in die Ausgangsposition schwenken. Darauf fährt die Kannenausfahrvorrichtung wieder zurück in ihre in Fig. 1 und 2 gezeigte Ausgangsposition. In der Zwischenzeit wurde eine leere Kanne entweder aus der Richtung C oder aus der Richtung D in die Kannenfüllposition gebracht. Der Kannenfüllvorgang kann anschliessend wieder gestartet werden.After the full can has reached its next functional position outside the can filling station, the pneumatic cylinder 16 is actuated again, so that the driver 10 and the arm 9 pivot back into the starting position. Thereupon the can extending device moves back into its starting position shown in FIGS. 1 and 2. In the meantime, an empty jug was moved from either direction C or direction D to the jug filling position. The can filling process can then be started again.

Die Fig. 3 und 4 zeigen eine Variante der Anwendung der erfindungsgemässen Vorrichtung, indem das Kannenausfahren und damit auch das Bandtrennen nicht mit einer geradlinigen Bewegung, sondern mit einer Kreisbewegung durchgeführt wird. Dementsprechend sind der Arm 9 und der Kannenmitnehmer 10 an einer Drehsäule 30 schwenkbar befestigt. Die Drehsäule 30 ist am oberen Ende in einem am Kopfteil 2 befestigten Lagerelement 31 und das untere Ende in einem zum Bodenteil 1 gehörenden Lagerelement 32 drehbar gelagert.3 and 4 show a variant of the application of the device according to the invention, in that the cans extend and thus also the strip cutting is carried out not with a straight movement but with a circular movement. Accordingly, the arm 9 and the can driver 10 are pivotally attached to a rotating column 30. The Rotary column 30 is rotatably supported at the upper end in a bearing element 31 fastened to the head part 2 and the lower end in a bearing element 32 belonging to the bottom part 1.

Beim Kannenausfahren muss der Arm 9 im Minimum so weit geschwenkt werden, dass die in Fig. 4 gezeigte Strecke B im Minimum der doppelten Länge der längsten im Band enthaltenen Faser entspricht.When the cans are extended, the arm 9 must be pivoted at least to such an extent that the distance B shown in FIG. 4 corresponds at least to twice the length of the longest fiber contained in the band.

Grundsätzlich ist das Stillsetzen der Ausgangsöffnung 5 nicht an eine Position innerhalb der Kreisbewegung der Oeffnung gebunden, vorausgesetzt, dass die die Strecke B betreffende Bedingung erfüllt ist.Basically, the stopping of the exit opening 5 is not tied to a position within the circular movement of the opening, provided that the condition relating to the route B is fulfilled.

Das Bewegen der Kannenausfahrvorrichtungen geschieht je durch einen Antrieb mit entsprechender Steuerung (beides nicht gezeigt), welche nicht Bestandteile dieser Erfindung sind.The can extenders are each moved by a drive with appropriate control (neither shown), which are not part of this invention.
