Description
Die Erfindung betrifft eine Vorrichtung zum Aufziehen kontinuierlich quergeförderter Schlauchabschnitte zum Zweck der Anformung von Böden bei der Sackherstellung mit paarweise vorgesehenen Tragrohren, von denen jedes die Koppel zweier in einem Maschinengestell drehbar gelagerter Parallellenker bildet und mit einer Reihe von radialen Saugern versehen ist, und mit einer mit einer Welle eines Parallellenkers verbundenen Kurbel, deren einen Gleitstein oder eine Rolle tragender Kurbelzapfen in einer auf einer Welle befestigten radialen Führung gleitet, wobei die Welle der Führung derart versetzt zu der Parallellenkerwelle gelagert ist, daß der Aufzugsbewegung der Saugerreihe eine im wesentlichen der Fördergeschwindigkeit entsprechende translatorische Bewegung überlagert ist.The The invention relates to a device for mounting continuously transversely conveyed hose sections for the purpose of molding soils in the production of sacks with paired support tubes, from each of which the coupling of two rotatable in a machine frame mounted parallel link forms and with a series of radial suckers is provided, and with one with a shaft of a parallel link associated crank, whose sliding block or a roller bearing Crank pin slides in a radial guide mounted on a shaft, being the wave of leadership is stored so offset from the parallel shaft, that the elevator movement the Saugerreihe a substantially corresponding to the conveying speed translational Movement superimposed is.

Aufgabe der Erfindung ist es daher, eine Vorrichtung der eingangs angegebenen Art zu schaffen, die ein verbessertes Aufziehen der Schlauchabschnittenden auch bei höherer Fördergeschwindigkeit ermöglicht.task The invention is therefore an apparatus of the initially mentioned To provide a type, the improved mounting the hose section ends even at higher conveyor speed allows.
Erfindungsgemäß wird diese Aufgabe bei einer Vorrichtung der gattungsgemäßen Art dadurch gelöst, daß die radiale Führung in der Weise kurvenförmig ausgebildet ist, daß die Phase des Gleichlaufs der Sauger mit dem Schlauchabschnitt verlängert ist. Durch eine entsprechende kurvenförmige Ausbildung der radialen Führung läßt sich bei verbessertem Gleichlauf die Eingriffszeit der Sauger an den aufzuziehenden Sackrändern verlängern, so daß eine bessere und insbesondere weitere Öffnung erzielt wird und ein störungsfreier Einlauf und Eingriff der die Eckeinschläge ausstreichenden Sicheln gewährleistet ist.According to the invention this Task in a device of the generic type solved in that the radial guide curved in the way is formed that the Phase of the synchronization of the teat with the tube section is extended. By a corresponding curved Formation of the radial guidance let yourself with improved synchronization, the intervention time of the suckers to the to be pulled up sack edges extend, so that one better and in particular further opening is achieved and a trouble-free Infeed and engagement of the sickles extending the corners guaranteed is.
Nach einer bevorzugten Ausführung der Erfindung ist vorgesehen, daß jedes Tragrohr drehbar in Haltestücken gelagert ist, die schwenkbar an den Parallellenkern gelagert sind, und daß auf das Tragrohr ein radialer Hebel drehfest aufgesetzt ist, der über einen Gleitstein oder eine Rolle auf einer mit dem zugehörigen Parallellenker fest verbundenen Kurve verläuft, die dem Tragrohr eine derartige Schwenkbewegung erteilt, daß die Ebene der Saugerteller jeder Reihe beim Aufziehen im wesentlichen parallel zu der Ebene der aufgezogenen Randstreifen der Schlauchstücke bleibt. Dadurch, daß den Saugerreihen während ihrer Aufzugsbewegung gleichzeitig eine Drehbewegung überlagert wird, wird ein Aufziehen ermöglicht, bei dem durch die Sauger der Rand des aufgezogenen Randstreifens nicht aus der dem Aufzugswinkel entsprechenden Ebene herausgebogen wird. Im Idealfall lassen sich die Randstreifen bis zur Ausbildung des Bodenquadrats aufziehen.To a preferred embodiment the invention is provided that each support tube rotatable in holding pieces is mounted, which are pivotally mounted on the parallel core, and that on the support tube, a radial lever is mounted rotatably, which has a Sliding block or a roller on one with the associated parallel link firmly connected curve runs, which gives the support tube such a pivoting movement that the plane the vacuum pad of each row when mounting substantially parallel remains to the plane of the raised edge strips of the hose pieces. The fact that the teat rows while their elevator movement simultaneously superimposed on a rotational movement is, a winding is possible, in which by the sucker the edge of the raised edge strip not bent out of the plane corresponding to the elevator angle becomes. Ideally, the margins can be up to training of the floor square.

Ein besonderes Problem bei dem Aufziehen der Randstreifen der Schlauchstücke besteht darin, daß die Randstreifen um ihre Faltlinien, die durch die äußeren Faltkanten definiert werden, abgewinkelt werden und sich dadurch gegenüber dem flachliegenden Mittelteil des Schlauchstücks schrägstellen, während die Ebene der Saugerteller parallel zu der Mittelebene der Schlauchstücke verbleibt.A particular problem with the mounting of the edge strips of the hose pieces is that the edge strips around their fold lines, which through the outer folding edges are defined, be angled and thereby inclined relative to the flat-lying central portion of the hose piece, while the plane of the suction cup remains parallel to the median plane of the hose pieces.
