Abstract

The invention concerns an unfolding station (B) for folded plastic fruit crates which are taken one by one from a stack in an upstream withdrawal station (A) and stacked at a downstream stacking station (C) for the unfolded crates (8). The crates (8), whose side walls (8l, 8b) are folded down onto the crate floor (8d), are unfolded when raised in relation to the feed and discharge line of the unfolding station.

Description

Es sind Kunsstoffsteigen bekannt, welche insbesondere für den Transport von Obst und Gemüse Verwendung finden und bei welchen die Seitenwände über ein Filmscharnier mit dem Boden verbunden sind, um am Boden anliegend zusammenfaltbar zu sein und so, während des Leertransportes, weniger Platz einzunehmen und öfters verwendbar zu sein. Bei derartigen Steigen erfolgt das Aufklappen der Seitenwände in der Regel nach einem Reinigungsvorgang mit Wasser. Dieses Aufklappen erwies sich als arbeitsaufwendig und unangenehm weil der Ausführende immer mit dem Restwasser in Berührung kommt welches von den Versteifungsstrukturen der Wände und des Bodens zurückgehalten wird; weiters bewirken die Bewegungen und der Druck welcher für das gegenseitige Einhängen der Seitenwände in aufgeklappter Position erforderlich sind, nach Wiederholung für eine ansehnliche Anzahl von Steigen, die Ermüdung des Ausführenden.Plastic trays are known, which in particular used for the transport of fruit and vegetables and in which the side walls over a film hinge connected to the floor to rest on the floor to be collapsible and so, during the Empty transport, taking up less space and more often to be usable. With such rises that happens The side walls usually open after one Cleaning process with water. This Unfolding proved to be labor intensive and uncomfortable because the operator is always with the Residual water comes into contact with which of the Stiffening structures of the walls and floor is withheld; the movements also have an effect and the pressure which is for mutual hanging the side walls in the opened position required are, after repetition for a substantial number of Rise, the fatigue of the performer.

Die Erfindung stellt sich die Aufgabe eine automatische Aufklappvorrichtung für zusammenfaltbare Steigen der eingangs beschriebenen Art zu schaffen, welche es ermöglicht, nach Entnahme von einzelnen Steigen in zusammengeklapptem Zustand von einem Stapel, diese durch Aufklappen der Seitenwände zu öffnen und anschließend wieder in aufgeklapptem Zustand zu stapeln.The invention has an automatic task Folding device for foldable climbing of the to create the type described above, which it allows you to remove individual trays in collapsed from a stack, this open by opening the side walls and then closed again in the opened state stack.

Zur Lösung dieser Aufgabe schlägt die Erfindung eine Vorrichtung zum Aufklappen vor, welche durch einen Mechanismus beschickt wird, der die zusammengeklappten Steigen einzeln aus einem Stapel entnimmt und welche am Ausgang mit einem Stapelmechanismus für aufgeklappte Steigen gekoppelt ist; weiters wird, um eine einzige lineare Vorrückrichtung der Steigen beizubehalten, vorgeschlagen, daß der Aufklappvorgang in erhöhter Stellung bezüglich der Beschickungs- und Ausgangsbewegung der Steigen erfolgt und daß in einer ersten Phase nach dem Vorrücken der Steige in Längsrichtung die Seitenwände mittels mit Greifelementen versehenen Schwenkarmen, welche an den entgegengesetzten seitlichen Rändern der beiden Längsseitenwände wirken, aufgeklappt werden, während in einem darauffolgendem zweiten Phase die Querseitenwände aufgeklappt werden, indem Schwenkarme mit ihren Greifelementen auf den oberen Rand dieser Wände wirken.
Erfindungsgemäß ist eines der Greifelemente der Schwenkarme, welche das Aufklappen der Längswände bewirken, feststehend oder in verschiedene Positionen feststehend einstellbar, während das andere Greifelement durch einen kleinen Pneumatikzylinder so betätigt wird, daß es einen leichten Druck auf die Seitenwand ausüben kann, um so eine Schubkraft in Richtung gegen das feststehende Greifelement zu bewirken. Die Greifelemente dieses Armes wirken übrigens immer in gleicher Höhe, unabhängig von der Höhe der Seitenwand. Die Schwenkarme für das Aufklappen der Querseitenwände hingegen sind einstellbar, um der Seitenwandhöhe angepaßt werden zu können. Weiters sind sie mit einem Greifelement versehen, welches von einem Pneumatikkolben betätigt wird.
Die Rotationsachsen dieser vorzugsweise pneumatisch betätigten Schwenkarme sind koaxial zur Achse der entsprechenden Filmscharniere angeordnet; um jedoch das Einschnappen der Einhängelemente zwischen den Längswänden und den Querwänden zu bewirken, schlägt die Erfindung vor, daß die Rotationsachse der Schwenkarme für das Aufklappen der Querseitenwände leicht nach unten versetzt ist, wodurch das Einschnappen der Einhängelemente begünstigt wird, indem während der letzten Aufklapp-Phase der Querseitenwände ein leichtes Niederdrücken dieser in Richtung Boden bewirkt wird, was ein Eingreifen und Einschnappen der Einhängeelemente ermöglicht. Diese Wirkung, welche durch die Versetzung zwischen der Scharnierachse und der Achse des Schwenkarms erzielt wird, ist insbesondere bei Steigen mit höheren Seitenwänden wichtig, weil diese auch in Zwischenbereichen über Einhängelemente verfügen.
Die Erfindung schließt das Durchlaufen der Steigen durch die Aufklappvorrichtung in Querrichtung nicht aus, auch in diesem Fall wird die Aufklappvorrichtung immer in einer ersten Phase das Aufklappen der Längsseitenwände der Steige und in der darauffolgenden Phase das Aufklappen der Querseitenwände durchführen. Nach dem Aufklappen der Steigenwände lassen die Greifelemente der Schwenkarme die Seitenwände frei und die Steige wird wieder auf die Ebene der Zuführbewegung abgesenkt, um weiter zur Stapelung befördert zu werden.To achieve this object, the invention proposes a device for opening, which is fed by a mechanism which takes the folded crates individually from a stack and which is coupled at the exit to a stacking mechanism for opened crates; Furthermore, in order to maintain a single linear advancement direction of the trays, it is proposed that the unfolding process takes place in an elevated position with respect to the loading and exit movement of the trays and that in a first phase after the advancement of the trays in the longitudinal direction, the side walls by means of swivel arms provided with gripping elements, which act on the opposite lateral edges of the two longitudinal side walls, are opened, while in a subsequent second phase the transverse side walls are opened by swivel arms with their gripping elements acting on the upper edge of these walls.
According to the invention, one of the gripping elements of the swivel arms, which causes the longitudinal walls to be opened, is fixed or adjustable in different positions, while the other gripping element is actuated by a small pneumatic cylinder in such a way that it can exert a slight pressure on the side wall in order to generate a pushing force in the direction against the fixed gripping element. Incidentally, the gripping elements of this arm always act at the same height, regardless of the height of the side wall. The swivel arms for opening the transverse side walls, on the other hand, are adjustable so that they can be adapted to the side wall height. Furthermore, they are provided with a gripping element which is actuated by a pneumatic piston.
The axes of rotation of these preferably pneumatically operated swivel arms are arranged coaxially with the axis of the corresponding film hinges; However, in order to cause the hooking elements to snap in between the longitudinal walls and the transverse walls, the invention proposes that the axis of rotation of the swivel arms for opening the transverse side walls be displaced slightly downward, which facilitates the snapging in of the hooking elements in that during the last opening Phase of the transverse side walls, a slight depression of this in the direction of the floor is effected, which enables the hooking elements to engage and snap in. This effect, which is achieved by the offset between the hinge axis and the axis of the swivel arm, is particularly important in the case of trays with higher side walls, because these also have hanging elements in intermediate areas.
The invention does not rule out the passage of the trays through the opening device in the transverse direction, also in this case the opening device will always open the longitudinal side walls of the tray in a first phase and open the transverse side walls in the subsequent phase. After opening the crate walls, the gripping elements of the swivel arms leave the side walls free and the crate is lowered again to the level of the feed movement in order to be further transported to the stacking.

Die Erfindung wird anhand eines, in den beigelegten Zeichnungen schematisch dargestellten Ausführungsbeispieles einer erfindungsgemäßen Aufklappvorrichtung für faltbare Steigen näher erklärt.The invention is based on one, in the enclosed Drawings shown schematically Embodiment of an inventive Folding device for foldable crates closer explained.

Die Fig.1 zeigt eine erfindungsgemäße Aufklappvorrichtung für faltbare Steigen im Längsschnitt, mit einer Steige beim Aufklappen und mit einer Steige in abgesenkter Stellung, um zur Stapelung befördert zu werden.1 shows an invention Folding device for foldable crates in Longitudinal section, with a crate when opening and with a crate in the lowered position to stack to be promoted.

Die Fig.2 zeigt die in Fig.1 dargestellte Aufklappvorrichtung für faltbare Steigen im Querschnitt, mit einer aufgeklappten Steige in oberer Stellung und mit einer weiteren aufgeklappten Steige in unterer Stellung, um zur Stapelung weiterbefördert zu werden.Figure 2 shows the one shown in Figure 1 Folding device for foldable crates in Cross-section, with an open crate in the upper Position and with another open crate in lower position to be transported to the stack will.

Der Aufklappstation B für die faltbaren Steigen 8, welche einen Boden 8d, zwei Längsseitenwände 8l und zwei Querseitenwände 8b aufweisen, geht eine Entnahmestation A der einzelnen Steigen von einem, auf Führungen 2 abgestelltem Stapel gefalteter Steigen voraus. Diese werden durch die geradlinige Hin- und Herbewegung 2b eines Mitnehmers 2a mit Schwenkklinke 1a, welcher die zusammengefaltete Steige auf die Führungen 3 eines vertikal arbeitenden Hebemechanismus 8b schiebt, vom Stapel entnommen. Dieser Hebemechanismus besteht im wesentlichen aus einem Arm 3a mit Führung 3b, welcher au einem vertikalen Rohr 3c durch den Pneumatikzylinder 3b senkrecht verschiebbar ist. An der gegenüberliegenden Seite ist derselbe Arm 3a mittels einer Gabel 3g an einem vertikalen Rohr 3f geführt. Die zusammengefaltete Steige 8 wird vertikal in die Aufklapposition 8c angehoben, in der in einer ersten Phase die Längsseitenwände 8l mittels der Schwenkarme 7a aufgeklappt werden; die Drehachse 7 der Schwenkarme ist dabei koaxial zur Achse der entsprechenden Filmscharniere der Wände am Boden 8d der Steige 8. Der Schwenkarm 7a verfügt über zwei Greifelemente 7b welche seitlich an den gegenüberliegenden seitlichen Rändern der Längsseitenwand 8l wirken. Eines dieser Greifelemente ist unverstellbar (Auflage) oder ist nach mehreren, vorgegebenen Positionen einstellbar während das zweite Greifelement 7f durch einen Pneumatikzylinder so betätigt wird, daß die Seitenwand 8l gegen das unverstellbare Greifelement gedrückt wird und dadurch festgehalten wird. Nach diesem Festhaltevorgang wird der Schwenkarm 7a durch die Pneumatikzylinder 7c in Richtung 7e geschwenkt um das Aufklappen der Längsseitenwände 8l zu bewirken. Zu der darauf folgenden Phase treten die Schwenkrahmen 6c für das Aufklappen der Querseitenwände 8b in Funktion, welche von den Zylindern 6e angetrieben werden.Diese Schwenkrahmen 6c sind so gelagert, daß ihre Rotationsachse 6 etwas tiefer in Bezug auf die Achse des Scharniers liegt, mittels welchem die Querseitenwände 8b am Boden 8d der Steige angelenkt sind. Die Schwenkrahmen 6c sind am Ende eines Winkelarms 6a mit einem Greifelement 6b versehen. Der Winkelarm 6a ist entsprechend der unterschiedlichen Höhe der Querseitenwände 8b der Steige einstellbar und wird durch einen Zylinder bewegt 6g, um die Querseitenwand 8b am oberen Rand zu ergreifen. Sobald das Aufklappen der Seitenwände stattgefunden hat und die Einhängeelemente zwischen den entsprechenden Seitenwänden eingeschnappt sind, lassen die Greifelemente 6b und 7b die Seitenwände frei, um mittels der durch die Zylinder 7c und 6e bewegten Arme 6a und 7a in die Ausgangsposition zurückgeschwenkt werden zu können. Anschließend wird die aufgeklappte Steige 8 durch die Bewegung des vom Zylinder 3d angetriebenen Armes 3a vertikal abgesenkt bis die Auflageführungen 3 für die Steige 8 wieder mit den Führungen 4 des Auslaufes aus der Aufklappstation B und mit den anschließenden Führungen 4a der Stapelstation für die aufgeklappten Steigen, ausgerichtet sind. Das Verschieben der aufgeklappten Steigen 8 längs dieser Führungen geschieht mittels eines Pneumatikzylinders 5c, welcher eine Schwenkklinke 5a betätigt.The folding station B for the foldable crates 8, which a bottom 8d, two longitudinal side walls 8l and have two transverse side walls 8b, one goes Withdrawal station A of the individual crates from one to Guides 2 parked piles of folded trays ahead. These are characterized by the straightforward back and forth Movement 2b of a driver 2a with swivel pawl 1a, which the folded crate on the Guides 3 of a vertical lifting mechanism 8b pushes, taken from the stack. This Lifting mechanism consists essentially of an arm 3a with Guide 3b, which on a vertical tube 3c through the Pneumatic cylinder 3b is vertically displaceable. At the opposite side is the same arm 3a by means of a fork 3g guided on a vertical tube 3f. The folded tray 8 is vertically into the Unfolded position 8c raised in the first phase the longitudinal side walls 8l by means of the swivel arms 7a be opened; is the axis of rotation 7 of the swivel arms thereby coaxial to the axis of the corresponding one Film hinges of the walls on the floor 8d of the tray 8. The Swivel arm 7a has two gripping elements 7b which laterally on the opposite side edges the long side wall 8l act. One of these Gripping elements is not adjustable (support) or is after several predetermined positions adjustable during the second gripping element 7f by one Pneumatic cylinder is operated so that the side wall 8l is pressed against the non-adjustable gripping element and is thereby held. After this Holding process is the swivel arm 7a by Pneumatic cylinder 7c pivoted in the direction of 7e Unfolding the long side walls 8l to effect. To the swiveling frame 6c for the following phase the opening of the transverse side walls 8b in function, which are driven by the cylinders 6e Swing frame 6c are mounted so that their Rotation axis 6 somewhat lower with respect to the axis of the hinge, by means of which the Cross side walls 8b articulated on the bottom 8d of the tray are. The swing frame 6c are at the end of one Angle arm 6a provided with a gripping element 6b. Of the Angular arm 6a is corresponding to the different Height of the transverse side walls 8b of the tray adjustable and is moved by a cylinder to the 6g To take the transverse side wall 8b at the top. As soon as the side walls have been opened and the hanging elements between the corresponding Sidewalls are snapped in, leave the Gripping elements 6b and 7b free the side walls by means of of the arms 6a and 6e moved by the cylinders 7c and 6e 7a to be pivoted back to the starting position can. Then the opened crate 8 by moving the 3d cylinder Arm 3a is lowered vertically until the support guides 3 for the crates 8 again with the guides 4 of the Outlet from the opening station B and with the subsequent guides 4a of the stacking station for the opened crates, are aligned. The Move the open crates 8 along this Guides are done by means of a pneumatic cylinder 5c, which actuates a pivot pawl 5a.
