Abstract

A workstation (1, 2, 3), with an upper part (6) and with a lower part (7), movable relative thereto, with an associated lifting device for executing the relative movement of the two parts, is provided. So that the lifting device on the one hand can exert high necessary forces for bringing together and closing the two parts, as is necessary, for example, in vacuum-packaging machines, but on the other hand can be constructed in a simple way, the lifting device has at least one pair of guide rods (9, 10, 11) which are oriented parallel to one another and which are connected to one another at their top end by means of the upper part (6) and at their bottom end by means of at least one yoke (18). Furthermore, the lifting device has guide bushes (23) which run on the guide rods and which are connected to the lower part (7). Finally, there is provided a toggle-lever system (24, 25) which is connected to the guide bushes (23) and which is designed so that, in the angled position, it keeps the lower part (7) in the lower position via the guide bushes (23) and, in its extended position, keeps the lower part (7) in the uppermost position. <IMAGE>

Description

Die Erfindung betrifft eine Arbeitsstation mit einem Oberteil und einem relativ dazu in eine abgesenkte Stellung senkbaren bzw. in eine angehobene Stellung anhebbaren Unterteil und einer Hubein-richtung zum Ausführen der Relativbewegung.The invention relates to a work station with an upper part and a lower part which can be lowered relative to it into a lowered position or raised into a raised position and a lifting device for executing the relative movement.

Eine solche Arbeitsstation wird in bekannter Weise als Bestandteil von Verpackungsmaschinen und insbesondere von Vakuumverpackungsmaschinen verwendet. Wegen der im Betrieb dabei auftretenden Kräfte sind die bekannten Arbeitsstationen sehr schwer gebaut.Such a work station is used in a known manner as a component of packaging machines and in particular of vacuum packaging machines. Because of the forces that occur during operation, the known work stations are very heavy.

Aufgabe der Erfindung ist es, eine Arbeitsstation der eingangs beschriebenen Art zu schaffen, die zu vergleichbaren Zwecken und insbesondere auch bei Vakuumverpackungsmaschinen einsetzbar ist und die erheblich leichter aufgebaut ist.The object of the invention is to provide a workstation of the type described in the introduction which can be used for comparable purposes and in particular also in vacuum packaging machines and which is of considerably lighter construction.

Diese Aufgabe wird durch die in Patentanspruch 1 gekennzeichnete Arbeitsstation gelöst.This object is achieved by the work station characterized in claim 1.

Weiterbildungen und Zweckmäßigkeiten der Erfindung sind in den Unteransprüchen gekennzeichnet.Further developments and expediencies of the invention are characterized in the subclaims.

Die in Fig. 1 gezeigte Verpackungsmaschine umfaßt eine als Tiefziehstation ausgebildete erste Arbeitsstation 1, eine als Evakuier- und Versiegelungsstation ausgebildete zweite Arbeitsstation 2 und eine als Schneidestation ausgebildete dritte Arbeitsstation 3. Die drei Arbeitsstationen werden von einem Maschinenrahmen 4 getragen, der gleichzeitig auch die Führung für einen nicht gezeigten Kettenantrieb zum Fördern des Verpackungsmaterials 5 bzw. der daraus zu bildenden Verpackungsbehälter aufweist.The packaging machine shown in FIG. 1 comprises a first work station 1 designed as a deep-drawing station, a second work station 2 designed as an evacuation and sealing station and a third work station 3 designed as a cutting station. The three work stations are carried by a machine frame 4, which at the same time also guides for a chain drive, not shown, for conveying the packaging material 5 or the packaging container to be formed therefrom.

Wie am besten aus den Fig. 2 bis 4 ersichtlich ist, weist die Arbeitsstation ein Oberteil 6 und ein damit zusammenwirkendes Unterteil 7 auf, die im Fall der Tiefziehstation im zusammengeführten Zustand durch Anlegen entsprechender Druckdifferenzen im Inneren zum Tiefziehen von Behältern 8 aus dem aus Folien gebildeten Verpackungsmaterial 5 dienen.As can best be seen from FIGS. 2 to 4, the work station has an upper part 6 and a cooperating lower part 7 which, in the case of the deep-drawing station in the merged state, by applying corresponding pressure differences inside for deep-drawing containers 8 from the film serve packaging material 5.

Die Arbeitsstation weist in ihrer Draufsicht eine im wesentlichen rechteckige Konfiguration auf. Das Oberteil wird an seinen vier Ecken von vier Führungsstangen 9, 10, 11 getragen. Zu diesem Zweck weist das Oberteil in seinen vier Ecken sich in vertikaler Richtung erstreckende und zueinander parallel ausgerichtete Bohrungen auf, die bezüglich ihrer Abmessung so bemessen und bezüglich ihrer Oberfläche so gestaltet sind, daß das Oberteil auf den Führungsstangen 9, 10, 11 gleiten kann. Es sind zur einstellbaren Verbindung des Oberteiles mit den Führungsstangen Schrauben 12, 13, 14 vorgesehen, durch deren Verstellung das Oberteil in einem kleinen Bereich auf den Führungsstangen nach unten verstellbar ist.The top view of the workstation is of a substantially rectangular configuration. The upper part is supported at its four corners by four guide rods 9, 10, 11. For this purpose, the upper part has bores in its four corners which extend in the vertical direction and are aligned parallel to one another, which are dimensioned in terms of their dimensions and designed in terms of their surface so that the upper part can slide on the guide rods 9, 10, 11. Screws 12, 13, 14 are provided for the adjustable connection of the upper part to the guide rods, by means of whose adjustment the upper part can be adjusted downwards in a small area on the guide rods.

An dem dem Oberteil 6 gegenüberliegenden unteren Ende der Führungsstangen sind diese mittels Reibschweißens mit Drehlagern 15, 16, 17 fest verbunden. Wie am besten aus den Fig. 2 und 3 ersichtlich ist, sind jeweils ein Paar von zusammengehörendem linken und rechten Drehlager 15, 16 durch ein Joch 18 miteinander verbunden. In der Richtung senkrecht dazu sind die jeweils zusammengehörenden Drehlager 16, 17 über eine Hubwelle 19 miteinander verbunden. Die Längenabmessungen von Joch 18 und Hubwelle 19 sind so bemessen, daß die damit verbundenen vier Führungsstangen Parallel zueinander ausgerichtet sind. Die Hubwellen weisen, wie am besten aus Fig. 2 ersichtlich ist, einen rechteckförmigen Querschnitt auf und besitzen an ihren Stirnseiten an einem Ende des rechteckförmigen Querschnittes Lagerzapfen, mit denen sie in den Drehlagern gelagert sind.At the lower end of the guide rods opposite the upper part 6, these are firmly connected by means of friction welding to rotary bearings 15, 16, 17. As can best be seen from FIGS. 2 and 3, a pair of associated left and right pivot bearings 15, 16 are connected to one another by a yoke 18. In the direction perpendicular to it, the pivot bearings 16, 17 which belong together are connected to one another via a lifting shaft 19. The length dimensions of yoke 18 and lifting shaft 19 are dimensioned such that the four guide rods connected to them are aligned parallel to one another. The lifting shafts, as can best be seen from FIG. 2, have a rectangular cross section and have bearing journals on their end faces at one end of the rectangular cross section, by means of which they are mounted in the pivot bearings.

Ferner umfaßt die Arbeitsstation des Unterteils 7 mit dem eigentlichen mit dem Oberteil zusammenwirkenden Kammerteil 20 und einem diesen tragenden Bodenteil 21. Der Bodenteil weist an den den Führungsstangen entsprechenden Stellen Führungsbuchsen 22, 23 auf, wie dies am besten aus Fig. 4 ersichtlich ist.Furthermore, the work station of the lower part 7 comprises the actual chamber part 20 interacting with the upper part and a bottom part 21 carrying the same. The bottom part has guide bushes 22, 23 at the points corresponding to the guide rods, as can best be seen from FIG. 4.

An zwei einander gegenüberliegenden Seiten der Arbeitsstation sind, wie am besten aus Fig. 2 und Fig. 3 ersichtlich ist, Paare von Kniehebeln 24, 25 vorgesehen. Diese weisen als unteren mit den Drehlagern 15, 16, 17 verbundene Schenkel auf, die durch die jeweilige Hubwelle 19 gebildet werden. Das von den den Lagerzapfen aufweisenden Ende gegenüberliegende Ende der rechteckigen Welle ist über eine Drehverbindung 26, 27 mit einem oberen Schenkel 28, 29 an einem von dessen Enden verbunden, der an seinem gegenüberliegenden freien Ende über eine Drehverbindung mit dem Bodenteil 21 verbunden ist. Der Verbindungspunkt zwischen den Schenkel 28, 29 und dem Bodenteil 21 liegt in vertikaler Richtung direkt über dem jeweiligen Lager der Hubwelle 19.As can best be seen from FIGS. 2 and 3, pairs of toggle levers 24, 25 are provided on two opposite sides of the work station. These have lower legs connected to the pivot bearings 15, 16, 17, which are formed by the respective lifting shaft 19. The end of the rectangular shaft opposite the end having the bearing journal is connected via a rotary connection 26, 27 to an upper leg 28, 29 at one of its ends, which is connected at its opposite free end to the base part 21 via a rotary connection. The connection point between the legs 28, 29 and the base part 21 lies in the vertical direction directly above the respective bearing of the lifting shaft 19.

Ferner ist nach Art eines Parallelogrammes eine Parallelstange 30 über zwei gleichlange Schenkel 31, 32 mit den Drehzapfen der Hubwellen 19 bzw. den Hubwellen selbst drehfest verbunden. Die Drehpunkte liegen so, daß eine Parallelogrammkonstruktion vorliegt. Schließlich ist eine pneumatisch oder hydraulisch angetriebene Kolben-Zylindereinrichtung 33 vorgesehen, die mit ihrem einen Ende am Joch 18 befestigt ist und mit dem freien Ende ihrer Kolbenstange an der Parallelstange 30 angreift.Furthermore, in the manner of a parallelogram, a parallel rod 30 is connected in a rotationally fixed manner to the pivots of the lifting shafts 19 or the lifting shafts themselves via two legs 31, 32 of equal length. The pivot points are such that a parallelogram construction exists. Finally, a pneumatically or hydraulically driven piston-cylinder device 33 is provided, which is fastened at one end to the yoke 18 and engages at the parallel rod 30 with the free end of its piston rod.

Wie am besten aus den Fig. 2 und 3 ersichtlich ist, ist die Kolben-Zylindereinrichtung derart angeordnet, daß das Unterteil 7 in zurückgezogener Stellung des Kolbens 34 der Kolben-Zylindereinrichtung das Kniehebelgelenk in seiner gefalteten Stellung und damit das Unterteil in seiner abgesenkten Stellung ist. In der ausgefahrenen Stellung des Kolbens 34 befindet sich das Kniehebelgelenk in seiner in Fig. 3 gezeigten gestreckten Stellung und damit das Unterteil in der oberen Stellung, in der die Kammer geschlossen ist. Gerade in dieser Stellung muß das Kniehebelgelenk die maximale Kraft tragen. Das ist trotz der nur aus einem Rechteckmaterial gebildeten Hubwelle 19 möglich, weil das Rechteckprofil hier in vertikaler Richtung ausgerichtet ist und in Arbeitsstellung die höchste Steifigkeit erreicht.2 and 3, the piston-cylinder device is arranged such that the lower part 7 in the retracted position of the piston 34 of the piston-cylinder device is the toggle joint in its folded position and thus the lower part in its lowered position . In the extended position of the piston 34, the toggle joint is in its extended position shown in FIG. 3 and thus the lower part is in the upper position in which the chamber is closed. In this position, the toggle joint must bear the maximum force. This is possible in spite of the lifting shaft 19 formed only from a rectangular material, because the rectangular profile is oriented here in the vertical direction and achieves the highest rigidity in the working position.

Für den Betrieb erfolgt zunächst über die oben beschriebene Schraubeinstellung mittels der Schrauben 12 und 13 eine Feineinstellung der Lage des Oberteiles derart, daß eine ausreichende Verschlußkraft genau dann zwischen den beiden Teilen wirksam ist, wenn der Kniehebelmechanismus in die in Fig. 3 gezeigte gestreckte Arbeitsstellung bewegt ist.For operation, the above-described screw adjustment by means of the screws 12 and 13 is used to fine-tune the position of the upper part such that a sufficient locking force is effective between the two parts when the toggle lever mechanism moves into the extended working position shown in FIG. 3 is.

Bei der in Fig. 4 gezeigten Ausführungsform ist zusätzlich zu der bereits beschriebenen Feineinstellung der Höhe des Oberteiles 6 über die Schrauben 12, 13, 14 zwischen dem Bodenteil 21 und dem Kammerteil 20 noch eine pneumatisch betätigbare großflächige Membraneinrichtung 35 vorgesehen, die über eine Pneumatikleitung 36 beaufschlagt wird. Bei dieser Ausführungsform erfolgt zunächst eine Voreinstellung über die Schrauben 12, 13, 14 für die Stellung des Oberteiles. Es wird dann das Unterteil in der oben beschriebenen Weise relativ zum Oberteil in die Schließstellung bewegt. Zur Erhöhung des Anpressdruckes zwischen Unterteil und Oberteil wird die Membran 35 mit Druckluft beaufschlagt, wodurch eine zusätzliche Anpresskraft ausgeübt wird. Anstelle der Membraneinrichtung können auch Kurzhubzylinder, Hydraulikzylinder oder eine Exzentereinrichtung zum Erzeugen der zusätzlichen hohen Schließkraft vorgesehen sein.In the embodiment shown in FIG. 4, in addition to the previously described fine adjustment of the height of the upper part 6 by means of the screws 12, 13, 14, a pneumatically actuated large-area membrane device 35 is provided between the base part 21 and the chamber part 20 is applied. In this embodiment, the screws 12, 13, 14 are first used for the position of the upper part. It then becomes the lower part in the manner described above moved relative to the upper part in the closed position. To increase the contact pressure between the lower part and the upper part, the membrane 35 is pressurized with compressed air, as a result of which an additional contact pressure is exerted. Instead of the membrane device, short-stroke cylinders, hydraulic cylinders or an eccentric device can also be provided to generate the additional high closing force.
