Abstract

Both the top side of the front door frame and the door angle piece on the housing side lie one hand-width above the top of the baling plunger plate when this is fully raised. The two parts (2a,b) of the fill shaft flap are joined to the door frame by gas springs etc in addition to their hinges (G,S) so that the free flap part (2b) can only be swung vertical when the flap as a whole has been horizontalised. An end stop (3a,b) limits the swivel movement of the free flap part in relation to the bottom flap part. Adjustable end stops (4,5) at the flap join at the free ends of the spacer bars (6) are mounted to the inside of the door. The two parts of the flap are of the same size, with the part hinged to the baling press frame (1) slightly deeper than part for preference. The frame of the front is finished as a hollow rectangular profile.

Description

Die Erfindung bezieht sich nach dem Oberbegriff des Patentanspruches 1 auf die Ausgestaltung der Fronttür von Ballenpressen mit vertikal wirkendem Preßstößel zur Erstellung abgebundener Ballen aus Kartonagen, Folien o.a. verbrauchten Verpackungsmaterialien.The invention relates to the preamble of Claim 1 on the design of the front door of balers with a vertical press ram for creating tied bales from cardboard boxes, Foils or similar used packaging materials.

Diese Fronttür besteht in bekannter Weise aus einem umlaufenden äußeren Hohl-Profilrahmen, der mitsamt der Türfüllung über Scharniere mit vertikaler Achse zum Zwecke der Entnahme fertiger Preßballen vom Pressengehäuse abgeschwenkt werden kann. Da vor der Ballenentnahme der fertig gepreßte Ballen noch abgebunden werden muß, bevor der Pressenstößel in seine oberste Totpunktlage hochgefahren werden darf, besteht bei den bislang bekannten Pressenausführungen die Gefahr, daß bei eventueller Unachtsamkeit einer der Bedienungspersonen eine eventuell vorhandene zweite, vor dem geöffneten Preßschacht stehende Person Quetschungen der Hände oder Unterarme erhalten Kann, wenn sich diese unachtsamerweise auf der Preßstößeloberseite abstützen bzw. auflehnen und der hochgehende Stößel den Bereich des obersten Türeinlaufwinkels am Pressengehäuse als Endpunkt erreicht.This front door consists of a known all-round outer hollow profile frame, the whole the door panel via hinges with a vertical axis for the purpose of removing finished bales from the press housing can be pivoted. Because before the bale is removed the finished pressed bale still tied must be before the press ram in its uppermost Dead center position may be raised at the press designs known so far the danger that in the event of carelessness, one of the operators a possibly existing second, before open squeeze standing person bruises of hands or forearms can get if this carelessly on the top of the ram support or lean and the rising plunger the area of the top door inlet angle on the press housing reached as the end point.

Ein weiterer Gefahrenpunkt bei allen bisher aus der Praxis bekannten Pressenausführungen dieser Bauart liegt noch darin, daß die frontseitigen Türblätter im Bereich des Einfüllschachtes im allgemeinen als mit Handbedienung mechanisch um eine horizontale Schwenkachse zu öffnende Klappe ausgebildet sind, die in geöffnetem Zustand in weitestgehend waagerechter Lage vom Pressengehäuse absteht. Bedingt hierdurch ergibt sich als Nachteil, daß durch diese abstehende Klappe die Bedienungsperson beim Einbringen der Abfallmaterialien in den Einfüllschacht nicht nahe genug an die Einwurföffnung herankommen kann, um einen optimalen Befüllungsgrad je Stößelhub zu erreichen. Eine Änderung der Türbauweise dergestalt, daß diese um eine vertikale Achse aufschwenkbar ausgebildet wird, scheidet von vornherein ebenfalls aus, da hierbei das Abfallmaterial noch schlechter beim Schließen einer solchen Tür in den Schacht der Presse gedrückt werden kann. Im Gegensatz zur Praxis ist zwar druckschriftlich aus der DE 31 12 914 A1 bereits ein Hinweis auf eine durch ein Horizontalgelenk unterteilte Einfüllschachttür bekannt, jedoch sind dazu aus dieser Druckschrift keinerlei bauliche und funktionelle Lösungsmerkmale zu entnehmen, wie eine derartige Klappe betriebssicher auszugestalten ist.Another point of danger with all so far from the Press versions of this type known in practice lies in the fact that the front door leaves in the area of the feed chute generally as with manual control mechanically around a horizontal Flap to open the swivel axis are formed, those in the open state are largely horizontal Position protrudes from the press housing. Because of this arises as a disadvantage that protruding through this Fold down the operator when loading the waste materials not close to the feed chute can get enough of the opening to to achieve an optimal filling level per ram stroke. A change in the door construction in such a way that they are designed to be pivotable about a vertical axis is also parting from the outset because the waste material is even worse when closing such a door in the shaft of the Press can be pressed. In contrast to practice is in print from DE 31 12 914 A1 already a reference to one by a horizontal joint divided hopper door known, however are no structural details from this publication and functional solution features such as to design such a flap in a reliable manner is.

Der Erfindung liegt daher die Aufgabe zugrunde, eine neue Tür-Gesamt-Konstruktion vorzugeben, die einerseits die Funktions-Vorteile der bekannten Türen beibehält und zudem für die Bedienungspersonen sowohl bei geöffneter Gesamttür als auch dem öffnungsvorgang der Einfüllschachtklappen keinerlei Gefahrenquellen mehr aufweist. The invention is therefore based on the object new door overall construction to specify the one hand maintains the functional advantages of the known doors and also for the operators both when open Overall door as well as the opening process of the Filler chute flaps no longer pose any danger having.

Gelöst wird diese Aufgabe bei einer Presse nach dem anmeldegemäßen Oberbegriff durch die im kennzeichnenden Teil des Patentanspruches 1 angegebenen baulichen Mittel und Maßnahmen; die Unteransprüche beinhalten vorteilhafte Weiterbildungen des neuen Systems, das zudem anhand von Zeichnungen in weitestgehend schematischer Weise in Form eines Ausführungsbeispieles dargestellt und im folgenden noch näher beschrieben ist.This task is solved in a press after generic term according to the registration in the characterizing Part of claim 1 specified structural Means and measures; which contain subclaims advantageous developments of the new system, the also largely schematic based on drawings Shown in the form of an embodiment and described in more detail below is.

Das in Fig. 1 weitestgehend schematisch von vorn gesehen dargestellte Pressengehäuse 1 mit vertikalem Stößelantrieb "ST" und zugehörigem Schaltkasten "K" ruht mit seinem Unterteil "U" auf dem Hallenboden "H" und ist in den Bereichen von Einfüllschacht "E" und Preßschacht "P" im Betriebszustand durch Türen 2a, 2b und 7 verschlossen.
Die Einfüllschachttür ist dabei als um eine horizontal liegende Achse "S" aufschwenkbare Klappe 2a, 2b ausgebildet und in horizontaler Ebene durch ein in einer Trennfuge "T" liegendes weiteres Gelenk "G" nochmals unterteilt, so daß der vordere, freie Klappenteil 2b zudem noch in die aus Fig. 7 ersichtliche bekannte Vertikalstellung heruntergeklappt werden kann.The press housing 1 with vertical plunger drive "ST" and associated switch box "K", shown largely schematically from the front in FIG. 1, rests with its lower part "U" on the hall floor "H" and is in the areas of the feed shaft "E" and press shaft "P" closed in the operating state by doors 2a, 2b and 7.
The hopper door is designed as a flap 2a, 2b which can be swung open about a horizontal axis "S" and is subdivided again in the horizontal plane by a further joint "G" located in a parting line "T", so that the front, free flap part 2b is also added can be folded down into the known vertical position shown in FIG. 7.

Für die aufgabengemäß betriebs- und unfallsichere Funktion dieser Klappe ist es nun von Bedeutung, daß beide Klappenteile 2a und 2b zusätzlich zu den Gelenkstellen G und S über Gasfedern o.ä. Bremselemente mit dem Pressengehäuse 1 verbunden sind, derart, daß das Abschwenken des vorderen freien Klappenteils 2b in die Vertikale (Fig. 7) erst nach dem Erreichen der Horizontallage der gesamten Klappe 2a, 2b erfolgt; der vordere Klappenteil 2b kann also niemals unkontrolliert herunterfallen und die Bedienungsperson gefährden.For the operational and accident-proof according to the task Function of this flap it is now important that both flap parts 2a and 2b in addition to Hinge points G and S over gas springs or similar Braking elements are connected to the press housing 1, such that the pivoting of the front free flap part 2b in the vertical (Fig. 7) only after The entire flap reaches the horizontal position 2a, 2b takes place; the front flap part 2b can never fall uncontrollably and the operator endanger.

Funktionell wichtig in diesem Zusammenhang ist zudem noch das Anbringen eines Begrenzungsanschlags 3a und 3b für den Abschwenkvorgang am vorderen freien Klappenteil 2b gegenüber dem unteren, am Gehäuse 1 angelenkten Teil 2a der Klappe 2a, 2b; hierdurch werden z.B. unkontrollierte Pendelbewegungen des freien Klappenteils 2b gegenüber 2a vermieden. It is also functionally important in this context still attaching a limit stop 3a and 3b for the pivoting process on the front free Flap part 2b opposite the lower one, on the housing 1 hinged part 2a of the flap 2a, 2b; hereby e.g. uncontrolled pendulum movements of the free flap part 2b compared to 2a avoided.

Für eine exakte Ausrichtung der beiden Klappenteile 2a und 2b im Schließzustand der Einfüllschachttür sorgen schließlich noch einstellbare Anschläge 4, 5 im Bereich der Trennfuge T zwischen den beiden Klappenteilen 2a und 2b an den freien Enden der auf der Türinnenseite angeordneten Abstandsleisten 6.For an exact alignment of the two flap parts 2a and 2b when the hopper door is closed finally provide adjustable stops 4, 5 in the area of the joint T between the two Flap parts 2a and 2b at the free ends of the spacer strips 6 arranged on the inside of the door.

In arbeitstechnischer Hinsicht hat es sich letztlich noch von Vorteil erwiesen, wenn beide Klappenteile 2a und 2b annähernd gleich groß sind bzw. das am Pressengestell 1 unmittelbar angelenkte untere Teil 2a etwas tiefer als das freie Teil 2b ist.In terms of work technology, it ultimately has still proven beneficial when both flap parts 2a and 2b are approximately the same size or that on Press frame 1 directly hinged lower part 2a is somewhat deeper than the free part 2b.

Hinsichtlich der Gesamtfronttür 7 liegt gemäß der Fig. 2 bis 4 das Neue vor allem darin, daß die Oberseite 7b des Rahmens 7a der Fronttür 7 sowie der gehäuseseitige Türenlaufwinkel 10 etwa eine Handbreite "SP" oberhalb der Oberseite 8a der Preßstößelplatte 8 in deren höchster Endstellung verlaufen, wobei in rein konstruktiver Hinsicht zudem noch vorgesehen ist, daß der Türrahmen 7a der Fronttür 7 aus einem rechteckigen Hohlprofil besteht. Diese Sicherheitsausgestaltung deckt somit bei geöffneter Füllklappe nach Fig. 3 einerseits den Raum oberhalb der Preßstößelplatte 8 derartab, daß kein Abfallmaterial bei der Befüllung des Preßschachtes nach oben gelangen und zu Betriebsstörungen führen kann und zeigt in Fig. 4 deutlich bei geöffneter Gesamtfronttür 7 den zumindest handbreiten Sicherheitsspalt "SP" zwischen der Oberseite 8a der Preßstößelplatte 8 in deren höchsten Endstellung sowie dem gehäuseseitigen Türenlaufwinkel 10. With regard to the entire front door 7 is according to the Fig. 2 to 4 the new mainly in that the top 7b of the frame 7a of the front door 7 and the Housing-side door bracket 10 about a hand's width "SP" above the top 8a of the ram plate 8 run in their highest end position, provided in purely constructive terms is that the door frame 7a of the front door 7 consists of a rectangular hollow profile. This Security design thus covers when open 3 filler flap on the one hand the space above the ram plate 8 so that no waste material when filling the press shaft can reach the top and lead to malfunctions and clearly shows in Fig. 4 with the entire front door open 7 the at least hand-wide security gap "SP" between the top 8a of the press ram plate 8 in their highest end position as well as on the housing side Door bracket 10.
