For the purpose, a clamping means (K) is coupled to the carrier member (15), for receiving the film or foil (62) or the like, wherein the clamping means comprises guide means (70) which are secured to the columns or pillars (5, 6) and on which there are slidably disposed slide members (71) which each have a respective lever (72) passing therethrough, each said lever being provided with a beak-like projection or lug (73) and being rotatable about an axis (A), the slide members and the levers together forming a clamping gap (74) for receiving the film or foil (62), wherein the lever (72) is connected to the carrier member (15) at the other end from the beak-like projection or lug (73). The method according to the invention is distinguished in that, when the carrier member is moved into a position below the heating device, the film or foil or the like is entrained by a clamping means and laid over the container. The film or foil is to be taken from a roll and fed to the clamping means, its direction being deflected into the direction of movement of the carrier member, by way of a slot.

Description

Die Erfindung betrifft eine Vorrichtung zum Aufsiegeln einer Folie od. dgl. auf einen Behälter mittels einer zwischen zwei von einer Traverse überspannten Säulen angeordneten absenkbaren Heizvorrichtung.The invention relates to a device for sealing a film or the like on a container by means of a lowerable heating device arranged between two columns spanned by a crossmember.

Eine derartige Vorrichtung ist beispielsweise aus der US-A 4092 817 bekannt. Dort wird ein Behälter unter eine Heizvorrichtung gestellt, eine Folie auf ihn aufgelegt und mittels der Heizvorrichtung aufgesiegelt.Such a device is known for example from US-A 4092 817. There a container is placed under a heating device, a film is placed on it and sealed by means of the heating device.

Der Erfinder hat sich zum Ziel gesetzt, das Aufbringen der Folie auf den Behälter zu automatisieren und so den Arbeitsablauf schneller auszugestalten.The inventor set himself the goal of automating the application of the film to the container and thus designing the workflow more quickly.

Zur Lösung dieser Aufgabe führt, dass der Behälter in einem Aufnahmeteil unter die Heizvorrichtung führbar und mit dem Aufnahmeteil eine Klemmeinrichtung zur Aufnahme der Folie od. dgl. gekoppelt ist.To achieve this object, the container can be guided in a receiving part under the heating device and a clamping device for receiving the film or the like is coupled to the receiving part.

Vorzugsweise soll die Klemmeinrichtung aus zwei jeweils an der Innenseite der Säulen festgelegten Führungen bestehen. Diese Führungen können einfache Schienenstücke beispielsweise rechteckigen Zuschnitts sein. Ihre Festlegung an den Säulen erfolgt durch Schrauben oder andere Befestigungsmittel. Auf diesen Führungen sind Läufer gleitbar angeordnet. Sowohl Läufer als auch Führungen sind jeweils von einem Hebel durchsetzt, welcher zusammen mit einem Teil der Oberfläche des Läufers und einem ihm angeformten Schnabelansatz einen Klemmspalt zur Annahme der Folie bildet. Nahe dem Schnabelansatz besitzt der Hebel eine Drehachse, um welche der Schnabelansatz zu der Läuferoberfläche hin- oder wegbewegt werden kann.The clamping device should preferably consist of two guides, each of which is fixed on the inside of the columns. These guides can be simple pieces of rail, for example rectangular cut. They are attached to the columns by screws or other fasteners. Runners are slidably arranged on these guides. Both runners and guides are each penetrated by a lever which, together with part of the surface of the runner and a beak attachment formed thereon, forms a clamping gap for accepting the film. Near the beak attachment, the lever has an axis of rotation about which the beak attachment can be moved toward or away from the rotor surface.

Dieser Hebel ist mit einem Fuss an das Aufnahmeteil angekoppelt. Die Verbindung zwischen Hebelfuss und Aufnahmeteil kann auf eine beliebige bekannte gelenkige Art erfolgen. Bevorzugt ruht der Fuss in einer dem Aufnahmeteil angeformten Rinne. So kann das Aufnahmeteil ohne Lösen von zusätzlichen Kopplungselementen von der Klemmeinrichtung getrennt werden.This lever is coupled with one foot to the receiving part. The connection between the lever foot and the receiving part can be made in any known articulated manner. The foot preferably rests in a groove formed on the receiving part. The receiving part can thus be separated from the clamping device without loosening additional coupling elements.

Die Drehachse, um welche der Hebel drehbar gelagert ist, wird bevorzugt nahe dem Schnabelansatz angeordnet, um die Hebelwirkung, welche beim Schieben des Aufnahmeteils über den Hebelfuss auf den Schnabelansatz einwirkt, zu vergrössern.The axis of rotation, about which the lever is rotatably mounted, is preferably arranged near the beak extension in order to increase the lever action which acts on the beak extension when the receiving part is pushed over the lever base.

Um den nötigen Bewegungsspielraum zu haben, ist die Führung durch eine Ausnehmung unterbrochen, in welcher der Hebel zusammen mit dem Läufer entlang der Führung gleiten kann.In order to have the necessary freedom of movement, the guide is interrupted by a recess in which the lever can slide along the guide together with the runner.

Vorzugsweise soll die Längsachse der Führungen schräg geneigt zur Schubrichtung des Aufnahmeteils verlaufen. Auf diese Weise kann der Klemmspalt zur Folie hingeführt und nach Aufnahme über den Aufnahmeteil bzw. den Behälter gelegt werden.The longitudinal axis of the guides should preferably be inclined at an angle to the direction of thrust of the receiving part. In this way, the clamping gap can be guided to the film and, after recording, can be placed over the receiving part or the container.

Weiterhin sollen die Läufer ihre jeweiligen Führungen klemmend umfassen. Um diese Kraft zu überwinden, muss der Druck auf den Aufnahmeteil erhöht werden. Dadurch erhöht sich aber auch die auf den Schnabelfortsatz des Hebels übertragbare Hebelkraft. Die Folie wird so besser gehalten.Furthermore, the runners should grip their respective guides in a clamping manner. In order to overcome this force, the pressure on the receiving part must be increased. However, this also increases the lever force that can be transferred to the beak extension of the lever. The film is held better this way.

Um in jedem Fall die Folie an der gleichen Stelle dem Klemmspaltzuführen zu können, soll nahe der Klemmeinrichtung in ihrer Endlage ein aus zwei Streifen gebildeter Schlitz angeordpet sein. In diesen Schlitz können einzelne fertig zugeschnittene Folienstücke eingeführt werden. Da jedoch bevorzugt die einzelnen Folienstücke von einer Rolle getrennt werden sollen, die zudem günstigerweise auf der Traverse gelagert ist, soll der Schlitz ein Knie bilden, durch welches die Folie in Schubrichtung des Aufnahmeteils umgelenktwird.In order to be able to feed the film to the clamping gap at the same point in any case, a slot formed from two strips should be arranged near the clamping device in its end position. Individual cut pieces of film can be inserted into this slot. However, since the individual pieces of film are preferably to be separated from a roll, which is also conveniently mounted on the crossmember, the slot should form a knee, through which the film is deflected in the direction of thrust of the receiving part.

Da das Einführen der Folie von einer Rolle und das Umlenken im Bereich des Knies ohne direkten Zugriff Schwierigkeiten bereitet, soll erfindungsgemäss der äussere Streifen der den Schlitz bildenden Streifen durch Langlöcher unterbrochen sein, welche den Zugriff zu der Folie erlauben.Since the introduction of the film from a roll and the deflection in the area of the knee are difficult without direct access, the outer strip of the strips forming the slit is to be interrupted by elongated holes which allow access to the film.

Um nun das Folienstück, welches auf den Behälter aufgesiegelt wird von der übrigen Rolle zu trennen, ist erfindungsgemäss nahe dem Schlitzauslauf eine Trenneinrichtung vorgesehen. Diese besteht in dem vorliegenden Ausführungsbeispiel aus einem Bügel mit einem Stirnbalken sowie zwei Tragarmen. Ein Trennwerkzeug unterfängt den Stirnbalken. In Ruhelage der gesamten Siegelvorrichtung soll erfindungsgemäss der Stirnbalken mit dem Trennwerkzeug von Teilen der Heizvorrichtung, insbesondere deren Abdeckbleche verdeckt sein. Dabei ragt jedoch der Stirnbalken jeweils seitlich aus dem Abdeckblech heraus und ist dort mit den Tragarmen verbunden. Diese Tragarme sollen nahe dem Stirnbalken über eine Drehachse aussen an der Heizvorrichtungsverkleidung angelenkt sein. Mit ihrem dem Stirnbalken fernen Ende sollen sie dagegen an den Säulen festgelegte Bolzen umfassen, wobei diese Bolzen in einer Ausnehmung bewegbar sind.In order to separate the piece of film which is sealed onto the container from the rest of the roll, a separating device is provided according to the invention near the slot outlet. In the present exemplary embodiment, this consists of a bracket with a front beam and two support arms. A separating tool underpins the front beam. In the rest position of the entire sealing device, according to the invention the front bar is to be covered with the separating tool from parts of the heating device, in particular the cover plates thereof. However, the front beam protrudes laterally out of the cover plate and is connected to the support arms there. These support arms are to be articulated near the end beam on the outside of the heater casing via an axis of rotation. With their end remote from the end beam, on the other hand, they are intended to comprise bolts fixed to the pillars, these bolts being movable in a recess.

Als Trennwerkzeug wird ein unterhalb des Stirnbalkens zwischen zwei Elektroden gespannter Heizdraht vorgeschlagen.A heating wire stretched beneath the end beam between two electrodes is proposed as the separating tool.

Im Rahmen der Erfindung liegen auch andere Ausführungsformen oder Halterungen für das Trennwerkzeug. So kann einfachheitshalber das Trennwerkzeug, also beispielsweise ein Heizdraht, direkt die untere Kante der Verkleidung unterspannen. Oder ein Stirnbalken ist zwischen den beiden seitlichen Verkleidungsblechen eingespannt und trägt das Trennwerkzeug. Beim Absenken der Heizvorrichtung trennt ein so befestigtes Trennwerkzeug ebenfalls wirkungsvoll das aufzusiegelnde Folienstück von der Rolle.Other embodiments or holders for the cutting tool are also within the scope of the invention. For the sake of simplicity, the separating tool, for example a heating wire, can be directly under the lower edge of the cladding. Or a front beam is clamped between the two side cladding panels and carries the cutting tool. When the heating device is lowered, a cutting tool fastened in this way also effectively separates the piece of film to be sealed from the roll.

Vorzugsweise umgibt die Verkleidung der Heizvorrichtung einen Heizkörper. Dieser kann bevorzugt aus zwei Platten bestehen, welche voneinander leicht trennbar sind. Hierzu hat der Erfinder einen Druckverschluss entwickelt, wobei aus der eigentlichen unteren Siegelplatte zumindest ein Stift aufragt, welcher mit einem kugelig ausgebildeten Kopf die andere Platte durchsetzt und dort druckknopfartig von zwei klemmenden Spangen gehalten wird. Hierdurch kann die Siegelplatte, die üblicherweise auf ihrer Unterseite Vorsprünge aufweist, welche durch die gewünschte Siegelnaht bestimmt werden, leicht ausgewechselt und der vorgegebenen Behälterform angepasst werden. Gedacht wird aber auch an andere übliche Befestigungselemente für zwei lösbare Platten.The casing of the heating device preferably surrounds a heating element. This can preferably consist of two plates which are easily separable from one another. For this purpose, the inventor has developed a pressure lock, at least one pin protruding from the actual lower sealing plate, which penetrates the other plate with a spherical head and is held there like a push button by two clamping clips. As a result, the sealing plate, which usually has projections on its underside, which are determined by the desired sealing seam, can be easily replaced and adapted to the predetermined container shape. However, other common fastening elements for two detachable plates are also considered.

Die Erfindung umfasst auch ein Verfahren zum Aufsiegeln einer Folie od. dgl. auf einen Behälter mittels einer zwischen zwei von einer Traverse überspannte Säulen angeordneten, absenkbaren Heizvorrichtung, unter welche der Behälter in einem Aufnahmeteil geführt wird, wobei die Folie od. dgl. beim Führen des Aufnahmeteils unter die Heizvorrichtung von einer Klemmeinrichtung mitgenommen und über den Behälter gelegt wird.The invention also encompasses a method for sealing a film or the like onto a container by means of a lowerable heating device arranged between two columns spanned by a crossbeam, under which the container is guided in a receiving part, the film or the like being guided the receiving part is taken under the heating device by a clamping device and placed over the container.

Die besondere vorteilhafte Ausgestaltung dieses Verfahrens liegt in der Automatisation des Aufsiegelvorganges, wobei der Arbeitsablauf erheblich beschleunigt wird.The particular advantageous embodiment of this method lies in the automation of the sealing process, the workflow being considerably accelerated.

Insgesamt ist die Vorrichtung ausserordentlich einfach ausgestaltet und deshalb sehr preisgünstig herzustellen. Sie eignet sich insbesondere für den Gebrauch beispielsweise in Fleischereien oder Einzelhandelsläden, welche keine hohen Investitionskosten für die bekannten teuren Siegelmaschinen aufbringen können. Durch die nun vorliegende Automatisation der Aufbringung des aufzusiegelnden Materials wird die Vorrichtung auch für Verbraucher attraktiv, welche sehr schnell und häufig Behälter verschliessen müssen.Overall, the device is extremely simple and therefore very inexpensive to manufacture. It is particularly suitable for use, for example, in butchers or retail stores, which cannot incur high investment costs for the known expensive sealing machines. Due to the automation of the application of the material to be sealed, the device is also attractive for consumers who have to close containers very quickly and frequently.

Zwischen den beiden Hülsen 28 sitzt eine Antriebseinrichtung 30, deren Innenteile von einer Schützhülle 31 umgeben sind, welche aus einem auf der Traverse 7 aufsitzenden unteren Teil 31a sowie einem dieses übergreifenden oberen Teil 31 besteht. Am Boden 32 des oberen Teils 31 b befindet sich eine Hutmutter 33.Between the two sleeves 28 there is a drive device 30, the inner parts of which are surrounded by a protective sleeve 31, which consists of a lower part 31 a seated on the cross member 7 and an upper part 31 overlapping this. At the bottom 32 of the upper part 31 b there is a cap nut 33.

Zum Versorgen der Vorrichtung S mit Energie ist eine Zuleitung 35 vorgesehen, welche zu einem Kippschalter 36 führt. Mit 37 ist eine Leitung der Antriebseinrichtung 30 und mit 38 eine mit einer wärmebeständigen Ummantelung versehene Leitung zur Heizvorrichtung 35 bezeichnet. Die Funktion der Antriebseinheit 30 sowie der Ablauf des Versiegelns von Behältern kann der Patentanmeldung DE-A-3210566.5 entnommen werden, wobei jedoch die vorliegende Erfindung auch bei Siegelgeräten od. dgl. mit einer anderen Antriebseinheit anwendbar ist.To supply the device S with energy, a feed line 35 is provided which leads to a toggle switch 36. 37 denotes a line of the drive device 30 and 38 denotes a line to the heating device 35 provided with a heat-resistant jacket. The function of the drive unit 30 and the sequence of the sealing of containers can be found in the patent application DE-A-3210566.5, but the present invention can also be used with sealing devices or the like with another drive unit.

Zusätzlich zu den in der oben genannten Patentanmeldung aufgeführten Einzelheiten sind bei dem vorliegenden Schutzbegehren Einrichtungen zum Nachbringen von Deckelfolie od. dgl. sowie eine Trenneinrichtung vorgesehen.In addition to the details listed in the abovementioned patent application, devices for adding cover film or the like and a separating device are provided in the present request for protection.

Auf der Traverse 7 lagert zwischen zwei Gerüststangen 60 eine Rolle 61 aus aufgewickeltem Deckelwerkstoff. Dieser Werkstoff kann in einer Bahn oder Folie 62 abgerollt werden, wobei er über eine Umlenkrolle 63, welche beispielsweise auch als Tänzerrolle ausgebildet sein kann, geführt wird. Sodann mündet die Folie 62 in einen aus zwei trichterförmig angeordneten Streifen 64 gebildeten Schlitz 65 und wird dort in einem Knie 66 etwa parallel zur Schubrichtung X umgelenkt. Der äussere Streifen 64a (Fig. 1) weist im Kniebereich Langlöcher 67 auf, über welche der Zugriff zur Bahn 62 ermöglicht und insbesondere das anfängliche Einlegen erleichtert wird.A roller 61 made of coiled cover material is supported on the crossmember 7 between two scaffolding bars 60. This material can be unrolled in a web or film 62, it being guided over a deflection roller 63, which can also be designed, for example, as a dancer roller. Then the film 62 opens into a slot 65 formed from two funnel-shaped strips 64 and is deflected there approximately parallel to the direction of thrust X in a knee 66. The outer strip 64 a (FIG. 1) has elongated holes 67 in the knee area, through which the access to the web 62 is made possible and in particular the initial insertion is facilitated.

Nach dem Einlegen in den Schlitz 65 kann die Bahn 62 von einer Klemmeinrichtung K ergriffen werden. Diese besteht nach Fig. 3 und 4 aus an den Säulen 5 und 6 festgelegten Führungen 70 zur Aufnahme von Läufer 71, welche zusammen mit jeweils einem um eine Achse A schwenkbaren Hebel 72 mit Schnabelansatz 73 einen Klemmspalt 74 bilden. Der Hebel 72 greift mit einem Fuss 75 in eine Rinne 76 ein, welche quer zur Schiene 10 an der Schublade 15 angeordnet ist.After insertion into the slot 65, the web 62 can be gripped by a clamping device K. According to FIGS. 3 and 4, this consists of guides 70, fixed to the columns 5 and 6, for receiving runners 71, which together with a lever 72 with a spigot 73, which can be pivoted about an axis A. Form clamping gap 74. The lever 72 engages with a foot 75 in a groove 76 which is arranged transversely to the rail 10 on the drawer 15.

Die Führungen 70, welche von den Läufern 71 schwergängig umfasst werden, weisen Längsachsen C auf, welche geneigt zur Längsachse des Gehäuses 1 verlaufen, so dass der jeweilige Klemmspalt zur Folie 62 bzw. dem Schlitz 65 hingeführt wird und nach Aufnahme der Folie 62 diese über die Schublade 15 bzw. den Behälter B abzieht. Um die Bewegung des Hebels 72 zusammen mit dem Läufer 71 zu ermöglichen weist die Führung 70 eine Ausnehmung 77 auf. Die erschwerte Bewegung des Läufers 71 auf der Führung 70 bewirkt, dass insbesondere beim Schieben der Schublade 15 mehr Kraft über die Rinne 76 auf den Hebel 72 und dort wegen der in Folge der nahen Lagerung der Achse A an dem Schnabelansatz 73 günstigen Kraftübertragung erheblich mehr Druck auf den Schnabelansatz 73 ausgeübt und der Halt der Folie 62 in dem Klemmspalt 74 verbessert wird.The guides 70, which are sluggishly encompassed by the runners 71, have longitudinal axes C, which run inclined to the longitudinal axis of the housing 1, so that the respective clamping gap is guided towards the film 62 or the slot 65 and, after receiving the film 62, over it pulls the drawer 15 or the container B. In order to enable the movement of the lever 72 together with the rotor 71, the guide 70 has a recess 77. The difficult movement of the runner 71 on the guide 70 has the effect that, in particular when pushing the drawer 15, more force via the groove 76 onto the lever 72 and there is considerably more pressure there because of the favorable force transmission due to the close mounting of the axis A on the beak shoulder 73 exerted on the beak shoulder 73 and the hold of the film 62 in the clamping gap 74 is improved.

Um nun das aufzu- oder aufgesiegelte Stück der Folie 62 von der Rolle 61 abzutrennen, sieht die Erfindung auch eine Trenneinrichtung T gemäss Fig. 5 vor. Diese besteht aus einem zwischen den beiden Säulen 5 und 6 gespannten Bügel 80, welcher so ausgelegt ist, dass er in Öffnungslage der Vorrichtung R mit seinem das eigentliche - nicht dargestellte - Trennwerkzeug aufweisenden Stirnbalken 81 hinter der Verkleidung 27 verschwindet, dessen seitliche Tragarme 82 aber aus der Verkleidung 27 herausgreifen und an den Säulen 5 und 6 sowie seitlichen Teilen der Verkleidung 27a angelenkt sind. Dabei besteht die Verbindung zwischen Verkleidung 27a und Tragarm 82 aus einer Drehachse D, während ein Bolzen 83 an der Säule 5 bzw. 6 in eine längliche Ausnehmung 84 am Fuss des Tragarms 82 eingreift. Auf diese Weise wird der Stirnbalken 81 bei der Bewegung des Heizkörpers 26 ebenfalls abgesenkt, jedoch im Verhältnis zu diesem um ein geringeres Mass, welches aber so ausgelegt ist, dass der Stirnbalken 81 mit seinem Trennwerkzeug dann auf die Bahn 62 trifft, wenn diese bereits von dem Heizkörper 26 auf die Öffnungsrandkante 16 des Behälters B gedrückt wird.In order to now separate the piece of film 62 which is to be sealed or sealed from the roll 61, the invention also provides a separating device T according to FIG. 5. This consists of a bracket 80 stretched between the two columns 5 and 6, which is designed such that it disappears behind the cladding 27 in the open position of the device R with its front bar 81, which has the actual - not shown - separating tool, but the lateral support arms 82 of the latter Grip out of the panel 27 and are articulated on the pillars 5 and 6 and lateral parts of the panel 27 a . The connection between cladding 27 a and support arm 82 consists of an axis of rotation D, while a bolt 83 on the column 5 or 6 engages in an elongated recess 84 at the foot of the support arm 82. In this way, the end beam 81 is also lowered when the heating element 26 moves, but in relation to it by a smaller amount, but which is designed so that the end beam 81 hits the web 62 with its separating tool when it is already on the radiator 26 is pressed onto the opening edge 16 of the container B.

Als Trennwerkzeug kommt insbesondere ein zwischen zwei Elektroden 85 gespannter Heizdraht in Betracht.A heating wire stretched between two electrodes 85 is particularly suitable as a separating tool.
