Description

Die Erfindung bezieht sich auf eine Vorrichtung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device according to the preamble of patent claim 1.

Ausgegangen zum Stand der Technik wird dabei von einem Verfahren samt zugehöriger Vorrichtung gemäß der DE-A-33 46 051 bzw. EP-A-0 149 774 des gleichen Erfinders. Diese bekannte Vorrichtung arbeitet zwar in der Praxis bereits seit Jahren mit großem Erfolg, bedarf jedoch, wie sich gezeigt hat, zu einer absoluten Optimierung aller Bedarfsfälle und völliger Vermeidung von Betriebsstörungen noch einiger Verbesserungen in verschiedenen Details.The state of the art is based on a method and associated device according to DE-A-33 46 051 and EP-A-0 149 774 by the same inventor. This known device has been working with great success in practice for years, but, as has been shown, it requires absolute optimization of all requirements and complete avoidance malfunctions and some improvements in various details.

Es ist deshalb Aufgabe der vorliegenden Erfindung, folgende Merkmale zu verbessern bzw. neu gegenüber dem Stand der Technik hinzuzufügen:

  • a. Ausbildung des Drahtdurchschubkopfes und der Verdrillfinger derart, daß bei jeder beliebigen Stellung derselben keine gegenseitige Kollision dieser Teile auftreten kann.
  • b. Möglichst nahe Zusammenführung der Abbindedrähte an den Verdrillstellen unter Vermeidung von Drahtumlenkungen im Bereich von 90°.
  • c. Mittel zur Gewährleistung einer stets richtigen Schneidposition des Drahtschnittstempels, auch bei einseitiger Preßplattenbelastung.
  • d. Mittel zum Verhindern des Wegspringens der Bindedrähte bei ggf. zu frühem Schnitt und noch nicht voll von den Verdrillfingern ergriffenen Drähten.
It is therefore an object of the present invention to improve the following features or to add new features over the prior art:
  • a. Form the wire feed-through head and the twisting fingers in such a way that no mutual collision of these parts can occur at any position thereof.
  • b. Bring the binding wires as close together as possible at the twisting points while avoiding wire deflections in the range of 90 °.
  • c. Means to ensure that the wire cutting die is always in the correct cutting position, even when the pressure plate is loaded on one side.
  • d. Means for preventing the binding wires from jumping off if the cut is too early and the wires are not yet fully gripped by the twisting fingers.

Die Lösung dieser vielschichtigen Aufgabe ist aus den Patentansprüchen zu ersehen und anhand eines zeichnerischen Ausführungsbeispiels im folgenden noch näher erläutert. Es zeigen im einzelnen:

Fig. 1
eine weitestgehend schematische Vorderansicht auf eine erfindungsgemäße Ballenpresse,
Fig. 2
die gegenüber Fig. 1 vergrößterte Seitenansicht einer Verdrillstation und
Fig. 3
eine Vorderansicht zu Fig. 2.
The solution to this complex task can be seen from the claims and explained in more detail below with reference to a drawing embodiment. The individual shows:
Fig. 1
a largely schematic front view of a baler according to the invention,
Fig. 2
the enlarged side view of FIG. 1 of a twisting station and
Fig. 3
2 shows a front view of FIG. 2.

Aus den Darstellungen in den Fig. 1 und 2 ist zunächst einmal der generelle Grundaufbau der neuen Abbindevorrichtung zu erkennen. Hierbei sind vor allem für das Überführen der Abbindedrähte 4, 5 von den Seitenwandungen des Preßschachtes 1 in den Bereich der Drillspindeln 12 bzw. der Drillfinger 11 je Abbindeebene E₁, E₂, E₃ einzelne und mechanisch nicht miteinander gekoppelte, hydraulisch bewegte Zylinder-Kolbeneinheiten 6, 7, 7a, 8 am Preßschacht 1 angeordnet, wobei jede der Kolbenstangen an ihrem freien, aus dem Hydraulikzylinder 6 herausragenden Ende einen Stangenkopf 7a trägt, der in seiner Endstellung über Führungen 7b im Preßkolben 2 in an sich bekannter Weise zentriert ist.
Das freie Ende jedes Stangenkopfes weist zudem in weiterhin bekannter Art neben den Führungsrollen FR für die Abbindedrähte 4, 5, einen mittig zwischen den Rollen FR liegenden Schneidstempel 9 auf, dessen Spitze Sp in Vorschubrichtung VR der Kolbenstange 7 gegenüber den Führungsrollenvorderkanten FRV um ein geringes Maß zurückversetzt ist. In gleicher Wirkungslinie liegt je Abbindeebene E₁, E₂, E₃ dem jeweiligen Schneidstempel 9 noch ein in axialer Richtung federnd nachgiebig gelagerter Amboß 10 gegenüber, der in seiner auf Block gefahrenen Endstellung an einem nicht dargestellten Schaltglied der Maschinensteuerung anliegt bzw. dieses niederdrückt.
The illustrations in FIGS. 1 and 2 first of all show the general basic structure of the new binding device. Here, especially for the transfer of the binding wires 4, 5 from the side walls of the press shaft 1 into the region of the twisting spindles 12 or the twisting fingers 11 per binding plane E 1, E 2, E 3, individual and mechanically not coupled, hydraulically moved cylinder-piston units 6, 7, 7a, 8 arranged on the press shaft 1, each of the piston rods having a free end protruding from the hydraulic cylinder 6 Rod head 7a carries, which is centered in its end position via guides 7b in the plunger 2 in a manner known per se.
The free end of each rod head also has, in a known manner, in addition to the guide rollers FR for the binding wires 4, 5, a cutting punch 9 located centrally between the rollers FR, the tip Sp of the piston rod 7 in the feed direction VR relative to the guide roller leading edges FRV by a small amount is set back. In the same line of action per binding plane E₁, E₂, E₃ the respective cutting punch 9 still has an anvil 10 resiliently mounted axially in the axial direction, which in its end position moved to the block rests against a switching element of the machine control (not shown) or depresses it.

Erfindungserheblich sind bei einer solchen Presse nun folgende Merkmale:

  • a. Der den Schneidstempel 9 und die Führungsrollen FR tragende Drahtführungskopf 8 ist in seiner Breite b schmaler ausgebildet als das Maß B der seitlichen Führungen 7b des Kopfes 7a der Kolbenstange 7 und ist zudem in seiner End- und somit Schneidposition in seitlich zum Amboß 10 liegenden Anschlägen 18 zwangsgeführt sowie zentriert.
    Hierdurch wird einerseits gewährleistet, daß von dem schmalen Drahtführungskopf wegen seines größeren Wandabstands, d.h. Spiels im Bereich der kolbenseitigen Durchführöffnungen so gut wie kein Abfallmaterial mitgezogen und in den Bereich des Ambosses 10 gestopft wird, und zum anderen sich die Schneidstempel 9 in einer stets optimalen Schneidposition auch bei einseitiger Preßplattenbelastung befindet.
  • b. Die Spindeln 12 der hakenförmigen Verdrillfinger 11 sind um ein solches Maß x abgekröpft ausgebildet, daß bei jeder beliebigen Maschinenstellung der Drahtführungskopf 8 bei seiner Bewegungsbahn stets außerhalb der Kreisbahn K der Verdrillfinger 11 verläuft - siehe hierzu auch Fig.3 - .
    Diese Kröpfung bringt zudem den Vorteil, daß an der eigentlichen Verdrillstelle von den Fingern 11 nur ein kleiner Drehkreis beschrieben wird, was zu einem besseren Verdrillergebnis führt und die vorgespannten Drähte 4, 5 festigkeitsmäßig nicht über Gebühr belastet.
  • c. Von den Außenwandungen 1a des Preßschachtes 1 aus erstrecken sich gabelförmige Fanghaken 19 beidseits bis an die Verdrillfinger 11 und umgreifen mit allseitigem Spiel die Abbindedrähte 4, 5 der Verdrill- und Durchschubseite. Diese Fanghaken sind somit Mittel zum Verhindern des Wegspringens der Bindedrähte bei ggf. zu frühem Schnitt und noch nicht voll von den Verdrillfingern ergriffenen Drähten.
The following features are relevant to the invention in such a press:
  • a. The width b of the wire guide head 8 carrying the cutting punch 9 and the guide rollers FR is narrower than the dimension B of the lateral guides 7b of the head 7a of the piston rod 7 and is also positively guided and centered in its end and thus cutting position in stops 18 lying laterally to the anvil 10.
    This ensures on the one hand that from the narrow wire guide head due to its greater wall distance, ie play in the area of the piston-side through openings, virtually no waste material is drawn and stuffed into the area of the anvil 10, and on the other hand the cutting punches 9 are always in an optimal cutting position even with one-sided pressure plate loading.
  • b. The spindles 12 of the hook-shaped twisting fingers 11 are cranked to such an extent x that the wire guide head 8 always runs outside of the circular path K of the twisting fingers 11 in its movement path in any machine position - see also FIG.
    This offset also has the advantage that only a small turning circle is described by the fingers 11 at the actual twisting point, which leads to a better twisting result and does not unduly stress the prestressed wires 4, 5 in terms of strength.
  • c. From the outer walls 1a of the press shaft 1, fork-shaped catch hooks 19 extend on both sides up to the twisting fingers 11 and encompass the binding wires 4, 5 of the twisting and push-through side with play on all sides. These catch hooks are thus means for preventing the binding wires from jumping off if the cut is too early and the wires are not yet fully gripped by the twisting fingers.

Erfindungserheblich ist in diesem Zusammenhang weiterhin die Anordnung je eines weiteren Führungsrollenpaares 20 für die Drähte 4 der Durchschubseite an entsprechenden Konsolen 21 zwischen Drahtführungskopf 8 und Kolbenstangenkopf 7a, wobei die Länge L der Konsolen 21 derart bemessen ist, daß die über die daran sitzenden Führungsrollen 20 laufenden Drähte 4 der Durchschubseite bis dicht an die Drähte 5 der Verdrillseite herangeführt sind. Durch diese vorteilhafte Anordnung sind im Verlauf der Bindedrähte 4 und 5 zudem nur noch Umlenkungen von mehr als 90° vorhanden, was u.a. zu einer erheblichen Verringerung des Kraftbedarfes für den Drahtdurchschub führt.In this context, the arrangement of a further pair of guide rollers 20 for the wires 4 on the push-through side on corresponding brackets 21 between wire guide head 8 and piston rod head 7a is significant to the invention, the length L of the brackets 21 being dimensioned such that the guide rollers 20 running thereon run over it Wires 4 of the push-through side are brought up close to the wires 5 of the twist side. Due to this advantageous arrangement, 4 are in the course of the binding wires and 5 only deflections of more than 90 ° are present, which among other things leads to a considerable reduction in the power requirement for the wire feed-through.

Rein baulich funktionell gesehen ist es letztlich noch von Bedeutung, daß in der Schneidstellung die zusätzlichen Führungsrollen 20 aus der Vorschubrichtung VR her gesehen unmittelbar vor den Fanghaken 19 liegen; beim Drahtdurchschub stabilisieren zudem die über die Führungsrollen 2a laufenden Drähte 4 die gesamte Vorschubeinheit.From a purely structural point of view, it is ultimately important that, in the cutting position, the additional guide rollers 20, as seen from the feed direction VR, lie directly in front of the catch hooks 19; when the wire is pushed through, the wires 4 running over the guide rollers 2a also stabilize the entire feed unit.
