Abstract

In order to be able to economically package with foil banderoles e.g. lettuces and bunches of carrots, asparagus, bananas, etc, the packaging apparatus has technical means for holding and grasping the foil web end, so that on removing the web from the foil web storage drum it can be placed round the article to be packaged and the foil web end can be kept within hand reach for new packaging processes. To this end, the foil web, together with its foil web storage drum is wound by means of a swivel round the article to be packaged, between two successive trays having a gap between them, the two ends of the article being supported on the trays. The gripping of the foil web end takes place by means of two foil web ends holding tubes, which are provided with circumferentially distributed air intakes and are connected to a vacuum producing device which can be switched on and off. The foil web is separated by means of a cutting knife.

Description

Die Erfindung betrifft eine Vorrichtung zum Verpacken von Kleinstückgütern, wie Salatköpfen, zu einem Bund zusammengelegten Mohrrüben, Spargeln, Bananen u. dgl., durch Umhüllen der Kleinstückgüter mit einer Banderole aus Kunststoffolie, insbesondere Dehnfolie mit Hilfe einer umlaufenden Folienbahnvorratstrommel und einer Trenn- und Haltevorrichtung.The invention relates to a device for packaging small items such as heads of lettuce, carrots folded into a bunch, asparagus, bananas and the like. Like., By wrapping the small items with a banderole made of plastic film, in particular stretch film with the help of a circumferential film web storage drum and a separating and holding device.

Neben dem Volleinschlag eines Verpackungsgutes mit Folie, die das Verpackungsgut allseitig umschließt, ist der Teileinschlag mittels einer Banderole bekannt, die das Verpackungsgut nicht vollständig umschließt, sondern zwei einander gegenüberliegende Seiten offen läßt. Der konstruktive Aufwand der bekannten Vorrichtungen zum Umhüllen von Verpackungsgut mit Banderolen ist sehr aufwendig, da einerseits eine Führung der Folienbahn um das Verpackungsgut gewährleistet werden muß und es zum anderen erforderlich ist, daß nach Beendigung eines Verpackungsvorganges das Ende der Folienbahn in eine griffgerechte Stellung gebracht und in dieser gehalten wird, damit für den nachfolgenden Verpackungsvorgang das Folienbahnende erfaßt und um das zu verpackende Gut gelegt werden kann.In addition to the full wrapping of a packaged item with film which surrounds the packaged item on all sides, the partial wrapping is known by means of a banderole which does not completely enclose the packaged item but leaves two sides opposite one another open. The design effort of the known devices for wrapping packaged goods with banderoles is very complex since, on the one hand, guiding the film web around the packaged goods must be ensured and, on the other hand, it is necessary that after the end of a packaging process the end of the film web is brought into a position within easy reach and is held in this so that the end of the film web can be grasped for the subsequent packaging process and placed around the goods to be packed.

Durch die dem Oberbegriff des Anspruchs 1 Zugrunde liegende DE-A-3 136435 ist eine Raff-und Schneidvorrichtung für Verpackungsmaschinen bekannt, bei der ein zu wickelndes Band mit Hilfe eines Führungselementes, beispielsweise einer Laufkatze, um das zu verpackende Gut herumgeführt und um dieses gewickelt wird.

Bei dieser Vorrichtung ist ein in dem Spannbereich des Bandes zwischen Laufbahn des Führungselementes und Gut an einer Stange befestigter fahrbarer Kopf vorgesehen, der bei eingezogener Stange an einem mit einer Schneid- und Haltevorrichtung für das Wickelband ausgerüsteten Gegenlager ruht, so daß ein Raffen, Ergreifen, Festhalten und Abschneiden des Bandes bzw. der Wickelfolie möglich ist. Diese Vorrichtung arbeitet in der Weise, daß der an der Stange befestigte fahrbare Kopf in Richtung des fortschreitenden Wickelvorganges ausfahrbar ist, wobei im ausgefahrenen Zustand sich das Band oder die Folie um die Stange herumlegt. Beim Einziehen der ausgefahrenen Stange legt sich das Gut bzw. die Folie von hinten an den Kopf und wird gegen das Gegenlager gezogen. An diesem Gegenlager kann dann auf verschiedene Weise ein Festhalten und Abschneiden erfolgen.DE-A-3 136435, on which the preamble of claim 1 is based, discloses a gathering and cutting device for packaging machines in which a band to be wound is guided around and wrapped around the goods to be packaged with the aid of a guide element, for example a trolley becomes. The gathering and cutting device is used to hold the tape to be wound, which can also be a film or the like, each time the goods to be wound change and to have the tape or film ready for the new material to be wound at the start of the winding process. In the case of this device, a mobile head is provided in the tensioning area of the belt between the track of the guide element and the good on a rod, which, when the rod is retracted, rests on a counter bearing equipped with a cutting and holding device for the winding tape, so that gathering, gripping, Holding and cutting the tape or the wrapping film is possible. This device works in such a way that the mobile head attached to the rod can be extended in the direction of the progressive winding process, with the tape or film wrapping around the rod in the extended state. When the extended rod is pulled in, the material or the film lies against the head from behind and is pulled against the counter bearing. This counter bearing can then be held and cut off in various ways.

The trolley is equipped with a supply roll from which the film strip is unwound. The goods to be packaged are fed slowly, during which they are wrapped in a spiral with the foil tape. When the end of the goods has been reached, which can be determined by a light barrier, the film strip to be wrapped is interrupted and gathered, so that it is readily available when the next packaging process starts. For this purpose, a gathering and cutting device is provided, the movement apparatus of which is arranged essentially to the side of the goods to be packaged, movement in the conveying direction or parallel to the axis direction of the winding process. In the tensioning area of the band, which is given in the present case through the opening of the ring, an extendable head is fastened to a rod, which can be pushed through the opening of the ring with the aid of a piston-cylinder arrangement. The head moves over the front of the wreath. As soon as the head with the rod is extended, a piece of the foil tape wraps around the rod. The trolley then runs up to about the zenith of the wreath and stops there due to the intended programming. The rod is then tightened by a corresponding pressure change in the piston-cylinder arrangement and then rests on a counter bearing. The counter bearing is provided with a cutting and holding device.

Zur Lösung dieser Aufgabe wird eine gattungsgemäße Verpackungsvorrichtung vorgeschlagen, die erfindungsgemäß in der Weise ausgebildet ist, daß in einem Tragrahmen zwei in Längsrichtung hintereinander und unter Ausbildung eines Zwischenraumes in einem Abstand voneinander angeordnete, das Verpackungsgut mit seinen Endbereichen aufnehmende Ablageschalen vorgesehen sind, daß ein um eine parallel zur Ablageschalenlängsachse verlaufende Drehachse mittels einer Antriebseinrichtung um mindestens eine volle und eine halbe Umdrehung drehbarer, um eine der beiden Ablageschalen, in deren dem Zwischenraum zugekehrten Endbereich umlaufender Drehring vorgesehen ist, der zwischen Lager- und Führungsrollen geführt ist und der eine seitlich auskragende, parallel zur Drehringdrechachse verlaufende, stabartige Halterung mit der mit dem Drehring gemeinsam, um den Zwischenraum zwischen den beiden Ablageschalen umlaufende Folienbahnvorratstrommel trägt, daß zwei in Längsrichtung hintereinander und unterhalb der Ablageschalen und in dem Innenraum des Drehringes liegende, über flexible Schlauchleitungen mit einer Vakuumerzeugungseinrichtung mit einem Ein-und Aussvhaltventil verbundene Folienbahnendehalterohre angeordnet sind, deren einander gegenüberstehende, unterhalb der Folienbahnvorratstrommel liegende Enden mit auf ihrem Umfang verteilt angeordneten Luftansaugöffnungen versehen sind und die als in feststehenden Führungen geführte Spindeln ausgebildet sind und zum Verfahren in Spindellängsrichtung mit den Kolbenstangen von zwei geeigneten Antriebseinrichtungen verbunden sind, daß ein in den Verpackungsgutfolienumhüllungsbereich mittels einer Antriebseinrichtung einfahrbares Trennmesser angeordnet ist und eine Steuereinrichtung vorgesehen ist, in der die Antriebseinrichtung für den Drehring mit der Folienbahnvorratstrommel, die Antriebseinrichtungen für die Folienbahnendehalterohre, das Ein- und Ausschaltventil für die Vakuumerzeugungseinrichtung und die Antriebseinrichtung für das Trennmesser zusammengeführt sind.To solve this problem, a generic packaging device is proposed, which is designed according to the invention in such a way that in a support frame Two storage trays are arranged one behind the other in the longitudinal direction and with the formation of an intermediate space and receiving the packaging material with its end regions, such that an axis of rotation running around a longitudinal axis parallel to the storage tray longitudinal axis can be rotated by at least one full and half a revolution by means of a drive device, by one of the two storage trays, in the end area facing the circumferential rotating ring is provided, which is guided between the bearing and guide rollers and a laterally projecting, parallel to the rotary ring axis, rod-like holder with the rotating ring together with the rotating space around the space between the two trays Foil web supply drum carries that two in the longitudinal direction one behind the other and below the storage trays and in the interior of the rotating ring, via flexible hose lines with a vacuum generating device with an inlet and outlet ntil connected foil end holder tubes are arranged, the opposite ends of which, below the foil web supply drum, are provided with air intake openings distributed over their circumference and are designed as spindles guided in fixed guides and are connected to the piston rods by two suitable drive devices for moving in the longitudinal direction of the spindle A separating knife which can be moved into the packaging material wrapping area by means of a drive device is arranged and a control device is provided in which the drive device for the rotating ring with the film web storage drum, the drive devices for the film web end holder tubes, the on and off valve for the vacuum generating device and the drive device for the separating knife are brought together .

Mit einer derart erfindungsgemäß ausgebildeten Vorrichtung ist das wirtschaftliche Verpacken von Kleinstückgütern mit einer Folienbanderole möglich. Insbesondere können mit der Vorrichtung auch Satatköpfe und zu einem Bund zusammengelegte Mohrrüben, Spargel, Bananen u. dgl. mit einer Folienbanderole versehen werden, die mit Preisangaben versehen werden können, wobei bei der Herstellung der Verpackung die hierfür verwendete Folienbahn bereits mit entsprechenden Preisangaben versehen sein kann; jedoch auch ein nachträgliches Bedrucken und Aufbringen von Preisangaben auf die angelegte Folienbanderole ist möglich.With a device designed in accordance with the invention, it is possible to pack small items economically with a film sleeve. In particular, satat heads and carrots, asparagus, bananas and the like can be folded into a bundle with the device. Like. Be provided with a film banderole, which can be provided with price information, wherein the film web used for this purpose can already be provided with corresponding price information during the manufacture of the packaging; however, it is also possible to subsequently print and apply price information to the created film sleeve.

Die Vorrichtung arbeitet mit einer hohen Wirtschaftlichkeit, da sie eine einfache Konstruktion aufweist und nur wenig Folie für den Verpackungsvorgang benötigt wird, so daß letztlich eine preisgünstige Verpackung erhalten wird.The device works with a high degree of economy, since it has a simple construction and only a little film is required for the packaging process, so that ultimately inexpensive packaging is obtained.

Mit einfachsten technischen Mitteln erfolgt das Halten bzw. Ergreifen des Folienbahnendes, um die Folienbahn durch Abziehen von einer Folienvorratstrommel um das Verpackungsgut legen zu können, wobei nach dem Abtrennen des um das Verpackungsgut herumgelegten Folienbahnabschnittes von der eigentlichen Folienbahn deren Ende für die Durchführung eines neuen Verpackungsvorganges in griffbereiter Stellung gehalten wird. Ein zusätzliches Andrücken des Endes des um das Verpackungsgut herumgelegten Folienbahnabschnittes nach dessen Abtrennen von der eigentlichen Folienbahn ist nicht erforderlich, da sich das Ende des Folienbahnabschnittes selbsttätig an die Folienumhüllung des Verpackungsgutes anlegt, während gleichzeitig das freie Ende der Folienbahn mittels Vakuum an zwei Folienbahnendehalterohren gehalten wird. Das Lösen des freien Endes der Folienbahn nach erfolgter Umhüllung eines Verpackungsgutes von den Folienbahnendehalterohren erfolgt durch Auseinanderfahren der Halterohre bei gleichzeitiger Drehung der Halterohre um ihre Längsachsen. Nur durch diesen Bewegungsablauf ist es möglich, die Folienbahn von den unter Vakuum stehenden Halterohren zu lösen, ohne daß dabei die Folienbahn verrutscht, zusammenfaltet od. dgl.The simplest technical means are used to hold or grasp the end of the film web in order to be able to place the film web around the goods to be packaged by pulling them off a film storage drum, with the end of the film web being separated from the actual film web from being separated from the actual film web for carrying out a new packaging process is kept in a handy position. An additional pressing of the end of the film web section around the packaging material after its separation from the actual film web is not necessary, since the end of the film web section automatically contacts the film wrapping of the packaging material, while at the same time the free end of the film web is held by vacuum on two film web end holder tubes . The release of the free end of the film web after the packaging material has been wrapped from the film web end holder tubes is carried out by moving the holding tubes apart while simultaneously rotating the holding tubes about their longitudinal axes. Only through this sequence of movements is it possible to detach the film web from the holding tubes under vacuum, without the film web slipping, folding or the like.

Besonders vorteilhaft ist die Verpackung von Salatköpfen mit der Folienbanderole unter Verwendung der Vorrichtung, da auf diese Weise eine Salatkopfverpackung geschaffen wird, die es ermöglicht, die sonst beim Verkauf von Salatköpfen sich ergebenden Nachteile zu vermeiden, die darin bestehen, daß zum Verkauf angebotene Salatköpfe nur mit aufwendigen Hilfsmitteln über einen längeren Zeitraum frischgehalten werden können. Die verwendeten Folienbanderolen sind verrottungsfrei und ermöglichen das Aufbewahren und Lagern derart verpackter Salatköpfe in wasserenthaltenden Behältern oder Wannen. Außerdem ergibt sich bei Anwendung der Vorrichtung ein geringer Folienverbrauch, da nur das Mindestmaß an Folie für die Umhüllung verwendet wird.The packaging of lettuce heads with the foil banding using the device is particularly advantageous, since in this way a lettuce head packaging is created which makes it possible to avoid the disadvantages that would otherwise arise when selling lettuce heads, which consist in the fact that lettuce heads offered for sale only can be kept fresh over a longer period of time with complex aids. The foil bands used are free from rot and enable the storage and storage of such packed heads of lettuce in water-containing containers or tubs. In addition, when using the device, there is low film consumption since only the minimum amount of film is used for the wrapping.

  • Fig. 3 in einer schematischen Seitenansicht den Verpackungsvorgang.
In the following the subject matter of the invention is explained in the drawings. It shows
  • 1 is a front view of the packaging device,
  • Fig. 2 is a top view of the packaging device, and
  • Fig. 3 in a schematic side view of the packaging process.

Die mit 100 bezeichnete und in Fig. 1 dargestellte Vorrichtung zum Verpacken von Kleinstückgütern, wie Salatköpfe, zu einem Bund zusammengelegte Mohrrüben, Spargel, Bananen u. dgl., besteht aus einem Tragrahmen 10, der mit Standholmen 13, 14 versehen sein kann, die an ihren bodenseitigen Enden 13a, 14a Laufrollen 15, 16 tragen, um die Verpackungsvorrichtung 100 an einen anderen Einsatzort verfahren zu können.The designated 100 and shown in Fig. 1 device for packaging small items, such as heads of lettuce, merged carrots, asparagus, bananas and the like. Like., consists of a support frame 10 which with Stand bars 13, 14 can be provided, which carry rollers 15, 16 at their bottom ends 13a, 14a in order to be able to move the packaging device 100 to another place of use.

In dem Tragrahmen 10 sind zwei Ablageschalen 11, 111 in Längsrichtung hintereinanderliegend angeordnet, wobei zwischen den einander zugekehrten Enden 11e, 111a derAbtagescha)en 11, 111 ein Zwischenraum 12 ausgebildet ist. Um die Breite des Zwischenraumes 12 verändern zu können, sind die Ablageschalen 11, 111 in dem Tragrahmen in in der Zeichnung nicht dargestellten Führungen gleitend gehalten, wobei die Ablageschalen 11, 111 in ihren jeweiligen Stellungen mit in an sich bekannter Weise ausgebildeten Feststelleinrichtungen , wie Klemmoder Verriegelungseinrichtungen, arretierbar sind. Beide Ablageschalen 11, 111 sind als Halbschalen und derart ausgebildet, daß das Verpackungsgut so in die Ablageschalen 11, 111 einlegbar ist, daß das Verpackungsgut V mit seinen Endbereichen in den Ablageschalen 11, 111 zu liegen kommt, während der mittlere Bereich des Verpackungsgutes V in dem Zwischenraum 12 zwischen den beiden Ablageschalen 11, 111 liegt. Die Verschiebbarkeit der beiden Ablageschalen 11, 111 zur Veränderung der Größe des Zwischenraumes 12 ist in Fig. 1 durch die Pfeile X, X1 angezeigt.In the support frame 10, two storage trays 11, 111 are arranged one behind the other in the longitudinal direction, a space 12 being formed between the mutually facing ends 11e, 111a of the storage trays 11, 111. In order to be able to change the width of the intermediate space 12, the storage trays 11, 111 are slidably held in guides in the support frame (not shown in the drawing), the storage trays 11, 111 in their respective positions using locking devices, such as clamps, or in a manner known per se Locking devices can be locked. Both storage trays 11, 111 are designed as half-shells and in such a way that the packaging material can be inserted into the storage trays 11, 111 in such a way that the packaging material V comes to rest with its end regions in the storage trays 11, 111, while the middle region of the packaging material V in the space 12 between the two trays 11, 111. The displaceability of the two storage trays 11, 111 to change the size of the intermediate space 12 is indicated in FIG. 1 by the arrows X, X1.

In dem Tragrahmen 10 ist ein senkrecht stehender Drehring 20 angeordnet, der in äußeren und inneren Lager- und Führungsrollen 23, 24 geführt und gehalten ist (Fig. 3). Diese Lager- und Führungsrollen 23, 24 sind an dem Tragrahmen 10 gehalten. Die Anordnung des Drehringes 20 in dem Tragrahmen 10 ist derart, daß seine bei 25 angeordnete Drehachse parallel zur Längsachse der Ablageschalen 11, 111 verlaufend ist. Des weiteren umläuft der Drehring eine der beiden Ablageschalen 11, 111. Bei dem in Fig. 1 gezeigten Ausführungsbeispiel ist der Drehring 20 zu der Ablageschale 11 derart angeordnet, daß der vordere Bereich 11 der Ablageschale 11 im Innenraum des Drehringes 20 zu liegen kommt, d.h. der Drehring 20 umläuft den Endbereich 11 der Ablageschale 11 und ist somit seitlich versetzt zu dem Zwischenraum 12 in dem Tragrahmen 10 angeordnet. Die Ablageschale 11 und auch die Ablageschale 111 liegen somit im Bereich der Drehachse 25 des Drehringes 20.In the support frame 10 a vertically rotating ring 20 is arranged, which is guided and held in outer and inner bearing and guide rollers 23, 24 (Fig. 3). These bearing and guide rollers 23, 24 are held on the support frame 10. The arrangement of the rotary ring 20 in the support frame 10 is such that its axis of rotation arranged at 25 is parallel to the longitudinal axis of the storage trays 11, 111. Furthermore, the rotating ring rotates around one of the two storage trays 11, 111. In the exemplary embodiment shown in FIG. 1, the rotating ring 20 is arranged in relation to the storage tray 11 in such a way that the front region 11 of the storage tray 11 comes to lie in the interior of the rotary ring 20, i.e. the rotating ring 20 runs around the end region 11 of the storage tray 11 and is thus laterally offset from the intermediate space 12 in the support frame 10. The storage tray 11 and the storage tray 111 are thus in the region of the axis of rotation 25 of the rotary ring 20.

Der Drehring 20 ist mittels einer Antriebseinrichtung 21 um seine Drehachse 25 in Pfeilrichtung Y verdrehbar (Fig. 3). Als Antriebseinrichtung 21 kann ein elektromotorischer Antrieb Verwendung finden; jedoch auch andere Antriebseinrichtungen können zum Einsatz gelangen. Ein auf der Welle der Antriebseinrichtung angeordnetes Antriebsrad 22 steht in Wirkverbindung mit dem Drehring 20, um diesen in Umdrehung versetzen zu können. Es besteht jedoch auch die Möglichkeit, die eine oder andere der Lager- und Führungsrollen 23, 24 als Antriebsrolle auszubilden und mit einem entsprechenden Antrieb in Verbindung zu bringen.The rotary ring 20 can be rotated about its axis of rotation 25 in the direction of the arrow Y by means of a drive device 21 (FIG. 3). An electromotive drive can be used as the drive device 21; however, other drive devices can also be used. A drive wheel 22 arranged on the shaft of the drive device is operatively connected to the rotary ring 20 in order to be able to set it in rotation. However, it is also possible to design one or the other of the bearing and guide rollers 23, 24 as a drive roller and to connect it to a corresponding drive.

Der Drehring 20 trägt eine seitlich auskragende und parallel zu seiner Drehachse 25 verlaufende, stabartige Halterung 26 in Form einer Lagerachse für eine Vorratstrommel 27 für eine Folienbahn FB. Diese Folienbahnvorratstrommel 27 ist mit einer in an sich bekannter Weise ausgebildeten Abzugsbremse, z.B. einer Reibungsbremse, versehen, um bei einem Folienabzug in Pfeilrichtung Z zu vermeiden, daß aufgrund des Freilaufs der Vorratstrommel mehr Folienbahn an Länge abgegeben wird, als benötigt wird.The rotating ring 20 carries a laterally cantilevered, rod-like holder 26, which runs parallel to its axis of rotation 25, in the form of a bearing axis for a storage drum 27 for a film web FB. This film web supply drum 27 is provided with a trigger brake, e.g. a friction brake, in order to avoid, in the case of a film pull-off in the direction of arrow Z, that because of the freewheeling of the storage drum, more film web is dispensed in length than is required.

Der Folienvorrat auf der Trommel 27 besteht aus einer Bahn aus Kunststoffolie, insbesondere aus Dehnfolie. Die Gesamtanordnung der Folienbahnvorratstrommel 27 in Verbindung mit dem Drehring 20 ist derart, daß die Folienbahn FB zwischen den beiden Ablageschalen 11, 111 hindurchführbar ist. Die Breite der Folienbahn FB ist etwas geringer bemessen als die Breite des Zwischenraumes 12 zwischen den beiden Ablageschalen 11, 111; die Folienbahnbreite wird sich jeweils nach der Länge des Verpackungsgutes und der jeweils gewünschten Verpackungsbreite richten. Dadurch, daß die beiden Ablageschalen 11, 111 in dem Tragrahmen 10 zur Veränderung des Zwischenraumes 12 verschiebbar sind, ist die Möglichkeit gegeben, breitere oder auch schmälere Folienbahnen verwenden zu können, so daß die jeweils günstigste Folienbahnbreite in Anpassung an das Verpackungsgut verwendet werden kann.The film supply on the drum 27 consists of a sheet of plastic film, in particular of stretch film. The overall arrangement of the film web supply drum 27 in connection with the rotating ring 20 is such that the film web FB can be passed between the two storage trays 11, 111. The width of the film web FB is dimensioned somewhat smaller than the width of the space 12 between the two storage trays 11, 111; the width of the film web will depend on the length of the packaged goods and the desired packaging width. Characterized in that the two storage trays 11, 111 are displaceable in the support frame 10 to change the space 12, it is possible to use wider or narrower film webs, so that the cheapest film web width can be used to adapt to the packaging.

Unterhalb der Ablageschalen 11, 111 sind in dem Tragrahmen 10 zwei Halterohre 30, 130 angeordnet, die zum Festhalten des Folienbahnendes FBI dienen. Diese Halterohre 30, 130 sind entsprechend den Ablageschalen 11, 111 hintereinanderliegend angeordnet, so daß ihre Mittellängsachsen miteinander fluchten. Die Anordnung dieser Halterohre 30,130 ist derart, daß ihre einander zugekehrten Enden 30a, 130a unterhalb des Zwischenraumes 12 zwischen den beiden Ablageschalen 11, 111 zu liegen kommen, so wie dies aus Fig. 1 ersichtlich ist.Below the storage trays 11, 111, two support tubes 30, 130 are arranged in the support frame 10, which serve to hold the film web end FBI. These holding tubes 30, 130 are arranged one behind the other corresponding to the storage trays 11, 111, so that their central longitudinal axes are aligned with one another. The arrangement of these holding tubes 30, 130 is such that their mutually facing ends 30a, 130a come to lie below the intermediate space 12 between the two storage trays 11, 111, as can be seen from FIG. 1.

Jedes der beiden Halterohre 30,130 weist an seinem Ende 30a bzw. 130a , und zwar über seinen Umfang verteilt, eine Anzahl von Luftansaugöffnungen 34, 134 auf. Des weiteren steht jedes Halterohr 30 bzw. 130 über eine flexible Schlauchleitung 31, 131 mit einer in dem Tragrahmen angeordneten Vakuumerzeugungseinrichtung 32, die mit einem Ein- und Ausschaltventil 33 versehen ist, in Verbindung.Each of the two holding tubes 30, 130 has a number of air intake openings 34, 134 at its ends 30a and 130a, distributed over its circumference. Furthermore, each holding tube 30 or 130 is connected via a flexible hose line 31, 131 to a vacuum generating device 32 which is arranged in the support frame and is provided with an on and off valve 33.

Die beiden Halterohre 30, 130 sind in dem Tragrahmen seitlich verfahrbar gehalten, so daß die freien Halterohrenden 30a, 130a mit ihren Luftansaugöffnungen 34,134 aus dem Bereich der Folienbahn FB herausführbar sind.The two holding tubes 30, 130 are held laterally movable in the support frame, so that the free holding tube ends 30a, 130a with their air intake openings 34, 134 can be led out of the area of the film web FB.

Für dieses seitliche Auseinanderfahren der beiden Halterohre 30,130 sind Arbeitszylinder 37, 137 in dem Tragrahmen 10 vorgesehen, die z. B. hydraulisch oder mit Druckluft betätigbar sind; jedoch auch andere geeignete Antriebseinrichtungen können hier Verwendung finden.For this lateral separation of the two holding tubes 30, 130, working cylinders 37, 137 are provided in the support frame 10, which, for. B. can be operated hydraulically or with compressed air; however other suitable ones Drive devices can be used here.

Die Kolbenstangen 38, 138 der beiden Arbeitszylinder 37, 137 sind mit den den die Luftansaugöffnungen 34, 134 tragenden Halterohrenden 30a, 130a abgekehrten Enden der Halterohre 30, 130 so verbunden, daß bei einer entsprechenden Betätigung der Arbeitszylinder 37, 137 die Kolbenstangen 38,138 mit ihren Halterohren 30, 130 in Richtung der Pfeile X2, X3 verfahrbar sind (Fig. 1) und daß sich dabei die Halterohre um ihre Längsachsen verdrehen können.The piston rods 38, 138 of the two working cylinders 37, 137 are connected to the ends of the holding tubes 30, 130 facing away from the holding tube ends 30a, 130a carrying the air intake openings 34, 134, so that when the working cylinders 37, 137 are actuated accordingly, the piston rods 38, 138 with theirs Holding tubes 30, 130 can be moved in the direction of the arrows X2, X3 (FIG. 1) and that the holding tubes can rotate about their longitudinal axes.

Um aber das Folienbahnende FBI von den Halterohrenden 30a, 130a bei angelegtem Vakuum lösen zu können, sind die Halterohre 30, 130 so ausgebildet, daß die Halterohre 30, 130 bei einem Auseinanderfahren sich auch gleichzeitig um ihre Längsachsen in Richtung der Pfeile X4, X5 verdrehen. Dieses Verdrehen der Halterohre 30,130 um ihre Längsachsen erfolgt durch eine spindelartige Ausgestaltung der beiden Halterohre 30,130. Auf ihrem Außenumfang sind beide Halterohre 30, 130 als Spindeln 36, 136, d.h. mit gewindeartigen Führungen, ausgebildet und sind darüber hinaus in feststehenden Führungen 35, 135 derart geführt, daß bei einem Auseinanderfahren der Halterohre 30,130 sich die Halterohre 30,130 um ihre Längsachsen verdrehen. Durch dieses Verdrehen der Halterohre 30, 130 ist es möglich, das Folienbahnende FBI aus der Halteposition an den Enden 30a, 130a der Halterohre 30,130 zu lösen.However, in order to be able to detach the FBI film web end from the holding tube ends 30a, 130a when a vacuum is applied, the holding tubes 30, 130 are designed such that the holding tubes 30, 130 simultaneously rotate about their longitudinal axes in the direction of the arrows X4, X5 when they are moved apart . This rotation of the holding tubes 30, 130 about their longitudinal axes takes place through a spindle-like configuration of the two holding tubes 30, 130. On their outer circumference, both holding tubes 30, 130 are as spindles 36, 136, i.e. formed with thread-like guides and are also guided in fixed guides 35, 135 such that when the holding tubes 30, 130 move apart, the holding tubes 30, 130 twist about their longitudinal axes. By rotating the holding tubes 30, 130, it is possible to release the film web end FBI from the holding position at the ends 30a, 130a of the holding tubes 30, 130.

Des weiteren ist in dem Tragrahmen ein Trennmesser 40 oder eine andere geeignete Folientrenneinrichtung vorgesehen (Fig. 3). Das Trennmesser 40 steht mit einer Antriebseinrichtung 41 in Verbindung, über die das Trennmesser 40 in den jeweiligen erforderlichen Trennbereich einführbar ist, um nach dem Anlegen der Banderole um das Verpackungsgut die Folienbanderole von der eigentlichen Folienbahn FB abtrennen zu können.Furthermore, a separating knife 40 or another suitable film separating device is provided in the supporting frame (FIG. 3). The separating knife 40 is connected to a drive device 41 via which the separating knife 40 can be inserted into the respective required separating area in order to be able to separate the film band from the actual film web FB after the band around the packaging material has been applied.

Alle Antriebseinrichtungen der Verpackungsvorrichtung 100 sind in einer Steuereinrichtung 50 zusammengeführt, mit der die einzelnen erforderlichen Verfahrensabläufe gesteuert werden. So sind in dieser Steuereinrichtung 50 die Antriebseinrichtung 21 für den Drehring 20 mit der Folienvorratsrolle 27, die Arbeitszylinder 37,137 für die Halterohre 30, 130, das Ein- und Ausschaltventil 33 für die Vakuumerzeugungseinrichtung 32 und die Antriebseinrichtung 41 für das Trennmesser 40 zusammengeführt (Fig. 1).All drive devices of the packaging device 100 are brought together in a control device 50, with which the individual required process sequences are controlled. In this control device 50, the drive device 21 for the rotary ring 20 with the film supply roll 27, the working cylinders 37, 137 for the holding tubes 30, 130, the on and off valve 33 for the vacuum generating device 32 and the drive device 41 for the separating knife 40 are brought together (FIG. 1).

Die Verpackungsvorrichtung 100 arbeitet wie folgt:The packaging device 100 works as follows:

Nach dem Auf setzen der Folienbahnvorratstrommel 27 auf die Lagerachse 26 an dem Drehring 20 wird die Vakuumerzeugungseinrichtung 32 in Betrieb genommen, so daß durch die Offnungen 34, 134 an den Enden 30a, 130a der Halterohre 30,130 Luft angesaugt wird. Die beiden Halterohre 30, 130 weisen in der Ausgangsstellung die in Fig. 1 gezeigte Stellung unterhalb des Zwischenraumes 12 zwischen den beiden Ablageschalen 11, 111 auf. Das zu verpackende Gut V wird in die Ablageschalen 11, 111 derart eingelegt, daß die Endbereiche des Verpackungsgutes V in den Ablageschalen 11, 111 zu liegen kommen. Der mittige freie Bereich des Verpackungsgutes V liegt dann in dem Zwischenraum 12.After putting on the film web supply drum 27 on the bearing axis 26 on the rotary ring 20, the vacuum generating device 32 is put into operation, so that air is sucked in through the openings 34, 134 at the ends 30a, 130a of the holding tubes 30, 130. In the starting position, the two holding tubes 30, 130 have the position shown in FIG. 1 below the space 12 between the two storage trays 11, 111. The goods to be packaged V are placed in the storage trays 11, 111 in such a way that the end regions of the packaging goods V come to rest in the storage trays 11, 111. The central free area of the packaging material V then lies in the intermediate space 12.

Von der Folienvorratstrommel 27 wird die Folienbahn von Hand in Pfeilrichtung Z soweit abgezogen, daß das Folienbahnende FBI im Bereich der Enden 30a, 130a der Halterohre 30, 130 zu liegen kommt, wobei das Folienbahnende FBI mit einem Abschnitt die Halterohrenden 30a, 130a umgreift (Fig. 3). Dadurch, daß die Halterohre 30, 130 an die Vakuumerzeugungseinrichtung 32 angeschlossen sind, wird über die Luftansaugöffnungen 34, 134 an den Halterohrenden 30a, 130a das Folienbahnende FBI an den Halterohren 30, 130 gehalten Ausgehend von der in Fig. 3 bei A gezeigten Stellung des Drehringes 20 mit der Folienbahnvorratstrommel 27 wird über die Steuereinrichtung 50 in Verbindung mit der Antriebseinrichtung für den Drehring 20 dieser in Pfeilrichtung Y in Umdrehung versetzt. An dieser Drehung des Drehringes 20 nimmt die Folienbahnvorratstrommel 27 teil und wird über die Stellungen B, C und D zunächst in die Ausgangsstellung A bewegt, wobei die Folienbahn FB um das Verpackungsgut V und um die Enden 30a, 130a der Halterohre 30, 130 gelegt wird. Da die beiden Halterohre 30,130 die in Fig. 1 gezeigte geschlossene Stellung aufweisen, wird beim Umlauf der Folienbahnvorratstrommel 27 die Folienbahn nicht nur um das Verpackungsgut V gelegt, sondern in dessen unteren Bereich auch um die Enden 30a, 130a der Halterohre 30, 130, wenn z. B. der Drehring 20 mit seiner Folienbahnvorratstrommel 27 die Stellung D in Fig. 3 erreicht hat.The film web is pulled off from the film supply drum 27 by hand in the direction of arrow Z to such an extent that the film web end FBI comes to rest in the region of the ends 30a, 130a of the holding tubes 30, 130, the film web end FBI encompassing a portion of the holding pipe ends 30a, 130a (FIG 3). Characterized in that the holding tubes 30, 130 are connected to the vacuum generating device 32, the film web end FBI is held on the holding tubes 30, 130 via the air intake openings 34, 134 on the holding tube ends 30a, 130a, starting from the position of A shown in FIG Rotating ring 20 with the film web supply drum 27 is set in rotation in the direction of arrow Y via the control device 50 in connection with the drive device for the rotating ring 20. The film web supply drum 27 takes part in this rotation of the rotating ring 20 and is first moved into the starting position A via the positions B, C and D, the film web FB being placed around the packaged goods V and around the ends 30a, 130a of the holding tubes 30, 130 . Since the two holding tubes 30, 130 have the closed position shown in FIG. 1, when the film web supply drum 27 rotates, the film web is not only placed around the packaged goods V, but also in the lower region around the ends 30a, 130a of the holding tubes 30, 130 if e.g. B. the rotary ring 20 with its film web drum 27 has reached position D in FIG. 3.

Während des Umlaufs des Drehringes 20 mit seiner Folienbahnvorratstrommel 27 von der Stellung A über die Stellungen B, C zur Stellung D wird von der Folienbahnvorratstrommel 27 nur soviel an Folienbahnlänge abgezogen, wie diese für den Umhüllungsvorgang des Verpackungsgutes V bei gleichzeitiger Führung der Folienbahn um die Enden 30a, 130a der Halterohre 30,130 benötigt wird. Die mit der Folienbahnvorratstrommel 27 in Wirkverbindung stehende Abzugsbremse verhindert, daß eine größere Länge an Folienbahn von der Trommel abgezogen wird, als diese benötigt wird.During the rotation of the rotating ring 20 with its film web supply drum 27 from position A via positions B, C to position D, only as much film web length is drawn off from the film web supply drum 27 as is required for the wrapping process of the packaging material V while simultaneously guiding the film web around the ends 30a, 130a of the holding tubes 30, 130 is required. The take-off brake which is operatively connected to the film web supply drum 27 prevents a greater length of film web from being pulled off the drum than is required.

Hat die Folienbahnvorratstrommel 27 die Stellung D (Fig. 3) erreicht, dann werden die beiden Arbeitszylinder 37, 137 eingeschaltet mit der Folge, daß die beiden Halterohre 30, 130 auseinanderbewegt werden, und zwar bei gleichzeitiger Drehung der Halterohre 30. 130 in Richtung der Pfeile X4, X5, so daß beim Auseinanderfahren der Halterohre 30, 130 und der gleichzeitig vollzogenen Drehbewegungen um die Längsachsen der Halterohre 30,130 das Folienbahnende FBI von den Enden 30a, 130a der Halterohre 30,130 gelöst wird, was durch diese Drehbewegungen möglich ist, da während des gesamten Vorganges die Vakuumerzeugungseinrichtung 32 eingeschaltet ist und Luft durch die Öffnungen 34, 134 in den Enden 30a, 130a der Halterohre 30, 130 angesogen wird. Vorzugsweise ist die Drehrichtung der Halterohre 30, 130 beim Auseinanderfahren gegenläufig. Nach dem erfolgten Auseinanderfahren der beiden Halterohre 30, 130 in eine Stellung, in der die Enden 30a. 130a der Halterohre 30,130 außerhalb der Folienbahn FB liegen, wird gleichzeitig der Drehring 20 in Pfeilrichtung Y weiterbewegt mit der Folge, daß auch seine Folienbahnvorratstrommel 27 weiterbewegt wird, was dazu führt, daß die Folienbahn an das Verpackungsgut V angelegt bzw. an das Verpackungsgut herangezogen wird, da für dieses Heranführen der Folienbahn an das Verpackungsgut der Weg durch die auseinandergefahrenen Halterohre 30,130 freigegeben ist.When the film web supply drum 27 has reached position D (FIG. 3), then the two working cylinders 37, 137 are switched on, with the result that the two holding tubes 30, 130 are moved apart, with simultaneous rotation of the holding tubes 30. 130 in the direction of Arrows X4, X5, so that when the holding tubes 30, 130 and the rotating movements about the longitudinal axes of the holding tubes 30, 130 move apart, the end of the film web FBI from the ends 30a, 130a Holding tubes 30, 130 is released, which is possible due to these rotary movements, since the vacuum generating device 32 is switched on during the entire process and air is drawn in through the openings 34, 134 in the ends 30a, 130a of the holding tubes 30, 130. The direction of rotation of the holding tubes 30, 130 is preferably in opposite directions when moving apart. After the two holding tubes 30, 130 have been moved apart into a position in which the ends 30a. 130a of the holding tubes 30, 130 lie outside the film web FB, the rotary ring 20 is simultaneously moved further in the direction of arrow Y, with the result that its film web supply drum 27 is also moved further, which leads to the film web being applied to the packaging material V or being used on the packaging material , since the path through the extended holding tubes 30, 130 is cleared for this approach of the film web to the packaged goods.

In dem Moment, in dem die Folienbahn an das Verpackungsgut V in dessen unteren Bereich angelegt ist, werden die beiden Halterohre 30, 130 mittels der Arbeitszylinder 37, 137 wieder in die geschlossene, in Fig. 1 gezeigte Stellung aufeinander zugefahren, wobei die Vakuumerzeugungs einrichtung 32 mittels des Ein- und Ausschaltventils 33 vorübergehend außer Betrieb gesetzt werden kann, da die Halterohre 30, 130 kein Folienbahnende zunächst zu halten brauchen.At the moment when the film web is applied to the packaging material V in its lower region, the two holding tubes 30, 130 are moved towards one another again by means of the working cylinders 37, 137 in the closed position shown in FIG. 1, the vacuum generating device 32 can be temporarily put out of operation by means of the on and off valve 33, since the holding tubes 30, 130 do not have to hold an end of the film web first.

Von der Stellung D bzw. A in Fig. 3 läuft dann die Folienbahnvorratstrommel 27 bei einer Weiterdrehung des Drehringes 20 noch einmal um das Verpackungsgut V herum bis erneut in etwa die Stellung D erreicht wird. Da jedoch während dieses Umlaufes bis zur Stellung D die beiden Halterohre 30,130 wieder die in Fig. 1 gezeigte geschlossene, d.h. aufeinanderzubewegte Stellung, aufweisen, verläuft die Folienbahn über einen Abschnitt des Außenumfanges der beiden Halterohrenden 30a, 130a. In diesem Moment wird die Vakuumerzeugungseinrichtung 32 wieder in Betrieb gesetzt, so daß die Folienbahn im Anlagebereich an den Halterohrenden 30a, 130a angesogen und von den Enden festgehalten wird. Während dieses Vorganges wird das Trennmesser 40 mittels der Antriebseinrichtung 41 in den Folienbahnbereich in Richtung des Pfeiles Z1 bewegt und trennt die Folienbahn von dem das Verpackungsgut V umhüllenden Folienbahnabschnitt. Das freie Ende FBI der Folienbahn FB wird von den Enden 30a, 130a der Halterohre 30, 130 gehalten, während das freie Ende desjenigen Folienbahnabschnittes, welches durch das Abschneiden von der Folienbahn FB freigelegt worden ist, an den Folienbahnabschnitt herangelegt wird, der bereits das Verpackungsgut V umgibt. Dieses Heranlegen des freien Endes des Folienbahnabschnittes, der um das Verpackungsgut V gelegt ist, erfolgt selbsttätig, und zwar aufgrund der Adhäsionskräfte, die zwischen diesem Folienbahnende und dem um das Verpackungsgut V herumgelegten Folienbahnabschnitt bestehen.From the position D or A in FIG. 3, the film web supply drum 27 then runs again around the packaged goods V when the rotary ring 20 continues to rotate until position D is reached again approximately. However, since during this cycle up to position D the two holding tubes 30, 130 again the closed one shown in FIG. have to move towards each other, the film web extends over a portion of the outer circumference of the two holding tube ends 30a, 130a. At this moment, the vacuum generating device 32 is put into operation again, so that the film web in the contact area is sucked onto the holding tube ends 30a, 130a and held by the ends. During this process, the separating knife 40 is moved by means of the drive device 41 into the film web area in the direction of arrow Z1 and separates the film web from the film web section enveloping the product V. The free end FBI of the film web FB is held by the ends 30a, 130a of the holding tubes 30, 130, while the free end of that film web section which has been exposed by cutting off the film web FB is placed against the film web section which already contains the goods to be packaged V surrounds. This positioning of the free end of the film web section, which is placed around the packaging material V, takes place automatically, because of the adhesive forces that exist between this film web end and the film web section wrapped around the packaging material V.

Das Verpackungsgut V ist somit banderotenartig umhüllt, d.h. verpackt, und wird aus den beiden Ablageschalen 11, 111 herausgenommen, während gleichzeitig der Drehring 20 in seiner Drehbewegung unterbrochen wird. Neues zu verpackendes Gut wird in gleicher Weise in die Ablageschalen 11, 111 eingelegt. Der Verpackungsvorgang, wie voranstehend beschrieben, kann erneut beginnen, da das freie Ende FBI der Folienbahn FB von den Halterohren 30, 130 festgehalten wird.The packaging material V is thus wrapped in a band red, i.e. packed, and is removed from the two storage trays 11, 111, while the rotary ring 20 is interrupted in its rotational movement. New goods to be packaged are placed in the storage trays 11, 111 in the same way. The packaging process, as described above, can start again since the free end FBI of the film web FB is held by the holding tubes 30, 130.
