Abstract
Die Erfindung betrifft eine Schalenverschließmaschine (1) und ein Verfahren mit einer manuell betätigbaren Anhebevorrichtung (16) für die Schalenaufnahme (2).The invention relates to a tray sealing machine (1) and a method with a manually actuable lifting device (16) for the tray receptacle (2).
Description
Die Erfindung bezieht sich auf eine Schalenverschließmaschine mit den Merkmalen des Anspruchs 1 sowie auf ein Verfahren gemäß Anspruch 7.The invention relates to a tray sealing machine having the features of claim 1 and to a method according to claim 7.
Aus der
Aufgabe der vorliegenden Erfindung ist es, eine Schalenverschließmaschine in einer vereinfachten Ausführung bereitzustellen.The object of the present invention is to provide a tray sealing machine in a simplified embodiment.
Diese Aufgabe wird gelöst durch eine Schalenverschließmaschine mit den Merkmalen des Anspruchs 1 und ein Verfahren gemäß Anspruch 7. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a tray sealing machine with the features of claim 1 and a method according to claim 7. Advantageous developments of the invention are specified in the subclaims.
Die erfindungsgemäße Schalenverschließmaschine umfasst ein Maschinenoberteil, ein Werkzeugoberteil und eine Schalenaufnahme, die eine oder mehrere Schalen aufnehmen kann, wobei die Schalenaufnahme horizontal in die Schalenverschließmaschine einschiebbar ist. Die Schalenverschließmaschine zeichnet sich dadurch aus, dass eine Anhebevorrichtung vorgesehen ist, die dazu konfiguriert ist, die Schalenaufnahme manuell an das Maschinenoberteiloberteil anzuheben, um eine Deckelfolie zu klemmen und eine evakuierbare und/oder begasbare Kammer zu bilden. Dies stellt eine konstruktiv sehr einfache Ausführung dar. Unter "manuell" wird im Rahmen der Erfindung verstanden, dass die jeweilige Bewegung - hier das Anheben der Schalenaufnahme mittels der Anhebevorrichtung - ohne Beitrag eines Motors bzw. Kraftantriebs erfolgt. Mit anderen Worten erfolgt das Anheben der Schalenaufnahme allein aufgrund der manuell vom Bediener der Schalenverschließmaschine ausgeübten Kraft. Dabei ist die Anhebevorrichtung dazu konfiguriert, diese ausgeübte Kraft in die Anhebebewegung zu überführen.The tray sealing machine according to the invention comprises a machine head, a tool top and a tray receptacle, which can receive one or more trays, wherein the tray receptacle is horizontally inserted into the tray closing machine. The tray sealing machine is characterized in that a lifting device is provided which is configured to manually lift the tray receptacle to the machine head top to clamp a lid sheet and form an evacuable and / or gasifiable chamber. This is a structurally very simple design. Under "manual" is understood in the context of the invention that the respective movement - here the lifting of the tray receiving means of the lifting device - without contribution of a motor or power drive. In other words, the lifting of the tray receptacle takes place solely on the basis of the force exerted manually by the operator of the tray closing machine. In this case, the lifting device is configured to transfer this applied force in the lifting movement.
Ideal ist es, wenn auch ein Einschieben der Schalenaufnahme in die Schalenverschließmaschine in diesem Sinne manuell durchgeführt wird, und zwar ohne dass der Bediener zwischen dem Einschieben der Schalenaufnahme und dem manuellen Betätigen der Anhebevorrichtung einen Griffwechsel durchführen muss. Stattdessen kann die Hand des Bedieners bei den beiden aufeinander folgenden Bewegungsabläufen am selben Handgriff der Schalenverschließmaschine verbleiben.It is ideal if insertion of the tray receptacle into the tray sealing machine is also carried out manually in this sense, without the operator having to change hands between the insertion of the tray receptacle and the manual actuation of the lifting device. Instead, the operator's hand may remain on the same handle of the tray sealer in the two consecutive motions.
Bevorzugt weist die Anhebevorrichtung jeweils zwei beidseitig an der Schalenaufnahme vorgesehene Klemmelemente auf.The lifting device preferably has two clamping elements provided on both sides of the shell receptacle.
Dabei sind die Klemmelement in einer besonders vorteilhaften Ausführung mittels eines Handgriffs synchron betätigbar. Die Klemmelemente weisen bevorzugt jeweils eine Abstützfläche zum Anheben der Schalenaufnahme auf.In this case, the clamping element in a particularly advantageous embodiment by means of a handle synchronously actuated. The clamping elements preferably each have a support surface for lifting the tray receptacle.
Dabei weisen die Klemmelemente vorzugsweise an der gegenüber der Abstützfläche liegenden Seite eine Kulisse zum Koppeln der Schalenaufnahme an das Maschinenoberteil auf. Dies bringt den Vorteil mit sich, dass die durch das Werkzeugoberteil auf die Schalenaufnahme aufzunehmenden Kräfte durch die Klemmelemente aufgenommen werden und eine aufwendige bzw. massive Verbindung zwischen dem Maschinenoberteil und einem Maschinenunterteil entfallen kann.In this case, the clamping elements preferably have on the opposite side of the support surface on a backdrop for coupling the tray receptacle on the machine head. This has the advantage that the forces to be absorbed by the tool upper part on the shell receptacle are absorbed by the clamping elements and a costly or massive connection between the machine head and a machine base can be omitted.
Vorzugsweise ist das Werkzeugoberteil mittels eines Hubantriebs vertikal relativ zum Maschinenoberteil und an die Schalenaufnahme bewegbar.Preferably, the upper tool part by means of a lifting drive is vertically movable relative to the machine head and the tray receptacle.
Ein erfindungsgemäßes Verfahren zum Betrieb einer Schalenverschließmaschine umfassend ein Maschinenoberteil, ein Werkzeugoberteil und eine Schalenaufnahme, die eine oder mehrere Schalen aufnimmt, zeichnet sich dadurch aus, dass nach einem Einschieben der Schalenaufnahme in die Schalenverschließmaschine die Schalenaufnahme manuell gegen das Maschinenoberteil angehoben wird, wobei dabei eine Deckelfolie umlaufend oder wenigstens an zwei gegenüberliegenden Seiten geklemmt und eine evakuierbare und/oder begasbare Kammer gebildet wird. Lediglich die Bewegung des Werkzeugoberteils erfolgt automatisch mittels eines Hubantriebs.An inventive method for operating a tray sealing machine comprising a machine head, a tool shell and a tray receptacle receiving one or more shells is characterized in that after insertion of the tray receptacle in the tray closing machine, the tray receptacle is manually raised against the machine head, wherein a Cover film circumferentially or at least clamped on two opposite sides and an evacuable and / or gastric chamber is formed. Only the movement of the upper tool part takes place automatically by means of a lifting drive.
Bevorzugt sind an der Schalenaufnahme beidseitig jeweils zwei Klemmelemente schwenkbar angeordnet und bei einer Drehung der Klemmelemente heben diese die Schalenaufnahme an, indem sie sich an einer Auflage eines Maschinenunterteils der Schalenverschließmaschine abstützen. Dies stellt eine besonders kostengünstige Konstruktion dar.Preferably, two clamping elements are pivotally arranged on both sides of the tray receptacle and upon rotation of the clamping elements, these lift the tray receptacle by being attached to a support of a machine base of the Support tray closing machine. This represents a particularly inexpensive construction.
Dabei erfolgt das Schwenken der Klemmelemente in einer besonders vorteilhaften Weise um einen Winkel von wenigstens 45°, vorzugsweise um wenigstens 60°.In this case, the pivoting of the clamping elements takes place in a particularly advantageous manner by an angle of at least 45 °, preferably by at least 60 °.
Vorzugsweise wird die Schalenaufnahme mittels der Klemmelemente an das Maschinenoberteil gekoppelt, um die hohen Siegelkräfte aufnehmen zu können, die ausgehend vom Werkzeugoberteil auf die Schalenaufnahme wirken. Dies ermöglicht eine platzsparende und konstruktiv einfache Konstruktion der Schalenverschließmaschine.Preferably, the shell receptacle is coupled by means of the clamping elements to the machine upper part in order to be able to absorb the high sealing forces that act on the shell receptacle starting from the upper part of the tool. This allows a space-saving and structurally simple construction of the tray sealing machine.
Bevorzugt wird nach dem Koppeln der Klemmelemente an das Maschinenoberteil mittels eines Hubantriebs das Werkzeugoberteil an die Schalenaufnahme abgesenkt, um die Deckelfolie an die Schale mittels Ausüben von Druck und Temperatur zu siegeln.Preferably, after the coupling of the clamping elements to the machine head by means of a lifting drive, the tool upper part is lowered onto the tray receptacle in order to seal the lid film to the tray by applying pressure and temperature.
Vorzugsweise wird die Deckelfolie mittels eines am Werkzeugoberteil angebrachten Schneidmessers entlang eines Schalenrands geschnitten, um einzelne geschlossene Verpackungen zu erhalten.Preferably, the cover sheet is cut along a tray edge by means of a cutting blade attached to the tool top to obtain individual closed packages.
