Description

AUFKLAPPVORRICHTUNG FÜR ZUSAMMENFALTBARE STEIGENFOLDING DEVICE FOR FOLDABLE RISKS
BESCHREIBUNGDESCRIPTION
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 desPlastic trays are known which are used in particular for the transport of fruit and vegetables and in which the side walls are connected to the floor via a film hinge in order to be able to be folded against the floor and so during the
Leertransportes, weniger Platz einzunehmen und öfters verwendbar zu sein. Bei derartigen Steigen erfolgt das Aufklappen der Seitenwände in der Regel nach einem ReinigungsVorgang mit Einsatz von 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.Empty transport, taking up less space and being usable more often. In such cases, the side walls are usually opened after a cleaning process using water. This unfolding turned out to be labor-intensive and uncomfortable because the operator always comes into contact with the residual water which is retained by the stiffening structures of the walls and floor; furthermore, the movements and the pressure which are required for the mutual hanging of the side walls in the opened position, after repetition for a considerable number of steps, cause the operator to become tired.
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 for its object to provide an automatic opening device for collapsible crates of the type described in the introduction, which makes it possible, after removing individual crates in the collapsed state from a stack, to open them by opening the side walls and then to stack them again in the collapsed state .
Zur Lösung dieser Aufgabe schlägt die Erfindung eine Vorrichtung zum Aufklappen vor welche durch einenTo achieve this object, the invention proposes a device for opening which by
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 einem ersten Moment, nach dem Vorrücken der Steige in Längsrichtung, die Seitenwände mittels, mitMechanism is loaded, which takes the folded crates individually from a stack and which is coupled at the exit with a stacking mechanism for opened crates; furthermore, in order to maintain a single linear advancement direction of the trays, 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 moment, after the advancement of the trays in the longitudinal direction, by means of
Greifelementen versehenen, Schwenkarmen welche an den entgegengesetzten seitlichen Rändern der beiden Längsseitenwände wirken, aufgeklappt werden während in einem darauffolgendem zweiten Moment die Querseitenwände aufgeklappt werden indem Schwenkarme mit ihren Greifelementen auf den oberen Rand dieser Wände wirken.Swivel arms provided with gripping elements, which act on the opposite lateral edges of the two longitudinal side walls, are opened up while in a subsequent second moment the transverse side walls are opened up by swivel arms with their gripping elements acting on the upper edge of these walls.
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. DieAccording to the invention, one of the gripping elements of the swivel arms, which causes the longitudinal walls to be opened, is fixed or can be fixed 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 provide a pushing force in the direction against the stationary gripping element. The
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.Incidentally, 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 in order to be able to be adapted to the side wall height, furthermore they are provided with a gripping element which is actuated by a pneumatic piston.
Die Rotationsachsen dieser, vorzugsweise pneumatisch betätigter, Schwenkarme sind koachsial mit der 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 derThe 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 snap-in 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 offset slightly downwards, thereby causing the snap-in of the
Einhängelemente begünstigt wird, indem während der letzten Aufklapp-Phase der Querseitenwände ein leichtes Niederdrücken dieser in Richtung Boden erzielt 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.Hook-in elements is favored by slightly depressing the transverse side walls in the direction of the floor during the last opening phase, which allows the hook-in elements to engage and snap in. This effect, what is achieved by the offset between the hinge axis and the axis of the swivel arm, is particularly important for crates with higher side walls because they also have hooking elements in intermediate areas.
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.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 transported further to the stacking.
Die Erfindung wird anhand eines, in den beigelegten Zeichnungen schematisch' dargestellten, Ausführungsbeispieles einer erfindungsgemäßen Aufklappvorrichtung für faltbare Steigen, näher erklärt; die Zeichnungen erfüllen dabei erklärenden, nicht einschränkenden Zweck.The invention is illustrated by way of, in the accompanying drawings schematically ', explains in more detail embodiment of a unfolding device according to the invention for folding climbing; the drawings serve an explanatory, non-limiting purpose.

Die Fig.2 zeigt die in Fig.l 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.2 shows the cross-section of the opening device for foldable crates shown in FIG. 1, with one crate open in the upper position and with another crate in the lower position in order to be conveyed further for stacking.
Der Aufklappstation B für die faltbaren Steigen 8 welche einen Boden 8d, zwei Längsseitenwände 81 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 la, welcher die zusammengefaltete Steige auf die Führungen 3 eines vertikal arbeitenden Hebemechanismus 8b schiebt, vom Stapel entnommen. Dieser Hebemechanismus besteht wesentlich aus einem Arm 3a mit Führung 3b, welcher am vertikalen Rohr 3c, durch den Pneumatikzylinder 3b senkrecht verschiebbar ist; an der gegenüberliegenden Seite ist der selbe Arm 3a mittels Gabel 3g am vertikalen Rohr 3f geführt. Die zusammengefaltete Steige 8 wird vertikal in die Aufklapposition angehoben 8c, wo in einem ersten Moment die Längsseitenwände 81 mittels der Schwenkarme 7a aufgeklappt werden; die Drehachse 7 der Schwenkarme ist dabei koachsial mit der 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 81 wirken. Eines dieserThe opening station B for the foldable crates 8, which have a bottom 8d, two longitudinal side walls 81 and two transverse side walls 8b, opens a removal station A of the individual crates from one Guides 2 parked stacks folded in advance. These are removed from the stack by the straight forward and backward movement 2b of a driver 2a with pivoting pawl 1a, which pushes the folded tray onto the guides 3 of a vertically operating lifting mechanism 8b. This lifting mechanism consists essentially of an arm 3a with a guide 3b, which is vertically displaceable on the vertical tube 3c by the pneumatic cylinder 3b; on the opposite side, the same arm 3a is guided by a fork 3g on the vertical tube 3f. The folded tray 8 is lifted 8c vertically into the opening position, where the longitudinal side walls 81 are opened up by means of the swivel arms 7a in a first moment; the axis of rotation 7 of the swivel arms is coaxial with the axis of the corresponding film hinges of the walls on the bottom 8d of the tray 8. The swivel arm 7a has two gripping elements 7b which act laterally on the opposite lateral edges of the longitudinal side wall 81. One of these
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 81 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 81 zu bewirken. Im darauf folgenden Moment 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 dieGripping elements is non-adjustable (support) or is adjustable according to several predetermined positions, while the second gripping element 7f is actuated by a pneumatic cylinder in such a way that the side wall 81 is pressed against the non-adjustable gripping element and is thereby held. After this holding process, the swivel arm 7a is swiveled in the direction 7e by the pneumatic cylinders 7c in order to bring about the opening of the longitudinal side walls 81. In the following moment the swivel frames 6c come into operation for opening the transverse side walls 8b which are driven by the cylinders 6e. These swivel frames 6c are mounted in such a way that their axis of rotation 6 is somewhat lower, with respect to the axis of the hinge by means of which the
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 dieTransverse side walls 8b are articulated to the bottom 8d of the tray. The swivel frames 6c are provided with a gripping element 6b at the end of an angle arm 6a. The angle arm 6a is adjustable and corresponding to the different height of the transverse side walls 8b of the tray is moved 6g by a cylinder to grip the transverse side wall 8b at the upper edge. As soon as the side walls have been opened and the hanging elements are snapped between the corresponding side walls, the
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. DasGripping elements 6b and 7b free the side walls in order to be able to be pivoted back into the starting position by means of the arms 6a and 7a, which are moved by the cylinders 7c and 6e. Then the opened crate 8 is lowered vertically by the movement of the arm 3a driven by the cylinder 3d, until the support guides 3 for the crate 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 ones Rise, are aligned. The
Verschieben der aufgeklappten Steigen 8 längs dieser Führungen geschieht mittels Pneumatikzylinder 5c welcher eine Schwenkklinke 5a betätigt. Moving the unfolded crates 8 along these guides takes place by means of pneumatic cylinder 5c which actuates a pivot pawl 5a.
