Definitions
- the invention relates to a device for strapping particularly compressible packaged goods such as corrugated cardboard layers or the like. according to the preamble of claim 1.
- Devices of this type which are also called “packaging presses”, have the task of tying compressible packaged goods on pallets or also without pallets to form compact containers.
- the device In order to apply the high compression pressure of up to over 5 t to the packaged goods, the device has a vertically movable press plate.
- the closure unit for the strapping means is motion-coupled, that is to say also arranged in a height-adjustable manner.
- the strapping unit is preceded by a strapping material store which holds a certain amount of strapping material, which thus does not have to be removed directly from the strapping material storage drum.
- the strapping zone is located below the press plate and consequently also under the sealing unit.
- Strapping of a packaged product takes place in such a way that the strapping material brought in from the strapping material supply is introduced and advanced from the closure unit into a section of an upper horizontal strapping material guide in such a way that it arrives via a first strapping material deflection into a strapping material guide which forms a post of the strapping frame. From there, the strap, again via a strap deflection, arrives in a lower, horizontal strap guide, that moves as a tongue or 'bayonet' under palletized goods. At the end of the closed bayonet, the strapping material then arrives in a second post opposite the first-mentioned post and finally after passing a last deflecting material deflection into the upper horizontal strapping means guide to the closure unit.
- the front strapping end is held in a clamping device of the closure assembly. Now the press plate moves down onto the packaged goods and compresses them. If the strapping material is now pulled back in the direction of the strapping material supply, the strapping material surrounding the packaged product peels out of the strapping means guides and stretches around the packaged product. The sealing assembly then welds the strapping sections overlapping in its effective area and separates the strapping on the side leading to the stock of strapping. In this way, the compressed packaged goods are now provided with a tight strapping.
- At least the closure unit associated with the press plate is located at heights far above the reach of the operator due to the design of such devices.
- a known device provides a strapping transfer in the form of a tubular channel, the side of which outside the strapping zone next to the Strapping portal arranged channel mouth forms a strapping feed into which strapping can be manually inserted and advanced to the sealing unit, from which the leading end of the strapping is then taken over.
- This auxiliary device saves tedious handling of the packaged goods and manual machine controls, for example to remove the packaged goods from the strapping zone, to lower the press plate, to provide the sealing unit with new strapping material, to raise the press plate again and to move the packaged goods back into the strapping position manual feeding of strapping overhead is always tedious and causes time-consuming business interruptions.
- the invention is therefore based on the object of specifying a device of the type outlined in the preamble of claim 1, in which interruptions in operation due to the need to supply strapping material to the closure assembly are minimized.
- the invention solves this problem in connection with the features of the preamble of claim 1 with the features specified in the characterizing part of this claim. This creates the possibility in any Operating position of the machine, including the press plate and the closing unit, to feed the latter to a new beginning of strapping. In addition, there is the possibility of doing this at least semi-automatically with a strapping means infeed device assigned to the strapping means feed, which - like the strapping means supply - is arranged near the ground and can therefore be easily accessed.
- the invention avoids another disadvantage inherent in the known device, which is that between the supply of strapping material and the mouth of the free end of the strapping material transfer, which mouth is at an alternatingly high level, a free strapping material tendon is always stretched, not only by carelessly carried loads can be damaged, but also represents a source of injury to people who approach it.
- additional strapping stock must be installed in the area of the strapping stock drum to accommodate the excess tape when the press plate is lowered.
- An overall designated 10 device for strapping particularly compressible packaged goods 11 such as corrugated cardboard layers or the like. initially comprises a supply of strapping material 12, which is raised near the ground, with a strapping means 14 wound on a drum 13, in particular a thermally weldable plastic band.
- a cross member 16 is arranged vertically movable in the direction of the double arrow 17.
- the cross member 16 forms a press plate for compressing the packaged goods 11 or is a component thereof and supports an assembly 18 on its upper side, which, in a manner to be described later, is used to transport the strapping means 14 and, above all, the training of a strapping fastener, which is why the unit will be referred to as a closing unit in the future.
- a strapping means storage 19 is assigned to the closure assembly 18 and, like the closure assembly 18, is driven in a movement-uniform manner and thus synchronously with the press plate 16 and is movably guided.
- Both the posts 15, 15 'and the cross member 16 are assigned strapping guides 20 to 23 in the form of straight channels or channel sections of a known type. It is also known to form the portal-like strapping guide channel structure 20 to 23 into a self-contained frame in that on the bottom side a lance traveling under the packaged goods 11 or the pallet on which it is stored, or a bayonet 24, which also contains a rectilinear strapping guide channel, 1 in the direction of arrow 42 of FIG. 1 in the position shown in FIG. 2 or 3.
- a strapping device infeed device 25 is provided close to the floor and immediately behind the strapping stock 12, which by means of strapping conveyor rollers 26, of which at least one is mechanically driven and the other is positively coupled to the strapping device feed, the strapping device 14 into one Push the strap guide 28 forward, which is arranged next to the post-like strap guide 21 and parallel to it.
- a strap deflection 29 arranged vertically movably, which has the task of transferring the strapping means 14 at the point at which the strapping means deflection 29 is located to a horizontally arranged strapping means transfer line 30, which leads it to the closure unit 18.
- a switch 31 located in the weft direction after the closing assembly 18, the starting position for a first strapping of a packaged product 11 is reached - see FIG. 1.
- Palletized or palletless packaged goods 11 to be strapped e.g. conveyed into the strapping zone by means of a roller conveyor (not shown).
- the strapping means 14 is then advanced by means of conveyor rollers 32, namely counterclockwise with respect to FIG. 2 through the strapping means guide 20, 21, 24, 22, and 23 as well as through the strapping means deflections 33 to 36 located in between in the strapping means path until the front end of the strapping means 14 comes back into the closure assembly 18.
- the drive of the strapping conveyor rollers 32 is reversed so that they pull back the strapping means 14 brought in by the strapping stock 12, while the other end of the strapping means is held on the closure assembly 18 by means of a clamp.
- the strapping means 14 is pulled out of the inside of all the strapping means guides which are designed for this in a known manner, for example thus flexible lips 39 as shown in FIG. 6 or flaps which open against spring action.
- the strapping means deflection designated 40 in the strapping means memory 19 is assigned a guide curve 42 which can be controlled (e.g. by means of a lifting magnet 41 - FIG. 4).
- the strapping device 14 can be fed to the closure assembly 18 from any position in the device 10 from the ground. After removal of any strapping material that may be in the machine, the new beginning of the strapping material is placed in the insertion device 25, which then automatically loads the device 10 with the strapping device 14 until it is taken over by the strapping device conveyor rollers 32 on or in the sealing unit 18. It is essential that, according to the invention, the additional strapping means 28 is provided with the strapping means deflection 29, which moves in the vertical direction synchronously with the strapping means 30, which in turn is assigned to the pressing plate 16 in a uniform movement.
- the strapping transfer 30 is set to be adjustable according to the movement of the assembly. In the exemplary embodiment, it can oscillate around the joints denoted by 37 and 38, the joint 37 being arranged in front of the strapping means deflection 29 and the joint 38 being carried by the closure assembly 18 or, in the specific exemplary embodiment, by the strapping means storage 19. Consequently, it is not only insignificant in which height position the pressing plate 16 is located if strapping means 14 has to be reinserted, the respective transverse position of the closure assembly 18 with regard to the strapping planes E1 and E2 is arbitrary.
- the strapping means 28 provided according to the invention for at least semi-automatic insertion can be one of the strapping guides 21, 22 and the strapping means 29 can be identical or even identical to one of the strapping means 33, 36. As shown in FIG. 7, the strapping means guide 28 is then only offset upwards relative to the strapping levels E1 and E2, since the strapping means 14 is to be fed in above the press plate 16.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Umreifen von insbesondere kompressiblem Packgut wie Wellpappelagen o.dgl. nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for strapping particularly compressible packaged goods such as corrugated cardboard layers or the like. according to the preamble of
Derartige Vorrichtungen, die man auch 'Verpackungspressen' nennt, haben die Aufgabe, kompressibles Packgut auf Paletten oder auch palettenlos zu kompakten Gebinden zu schnüren. Um den hohen Kompressionsdruck von bis zu über 5 t auf das Packgut aufzubringen, weist die Vorrichtung eine vertikal bewegbare Pressplatte auf. Mit dieser ist das Verschlußaggregat für das Umreifungsmittel bewegungsgekuppelt, also ebenfalls höhenverstellbar angeordnet. In der Regel ist dem Verschlußaggregat noch ein Umreifungsmittelspeicher vorgeordnet, der eine gewisse Menge an Umreifungsmittel vorhält, welches somit nicht direkt von der Umreifungsmittel-Vorratstrommel abgezogen werden muß. Die Umreifungszone befindet sich unterhalb der Pressplatte und folglich auch unter dem Verschlußaggregat.Devices of this type, which are also called “packaging presses”, have the task of tying compressible packaged goods on pallets or also without pallets to form compact containers. In order to apply the high compression pressure of up to over 5 t to the packaged goods, the device has a vertically movable press plate. With this, the closure unit for the strapping means is motion-coupled, that is to say also arranged in a height-adjustable manner. As a rule, the strapping unit is preceded by a strapping material store which holds a certain amount of strapping material, which thus does not have to be removed directly from the strapping material storage drum. The strapping zone is located below the press plate and consequently also under the sealing unit.
Eine Umreifung eines Packguts erfolgt dergestalt, daß das vom Umreifungsmittelvorrat herangeführte Umreifungsmittel vom Verschlußaggregat aus in einen Abschnitt einer oberen horizontalen Umreifungsmittelführung eingebracht und vorgeschoben wird, derart, daß es über eine erste Umreifungsmittel-Umlenkung in eine Umreifungsmittelführung gelangt, die einen Pfosten des Umreifungsmittelrahmens ausbildet. Von dort gelangt das Band, wiederum über eine Umreifungsmittel-Umlenkung in eine untere, horizontal verlaufende Umreifungsmittelführung, die als Zunge oder auch 'Bajonett' unter palettiertes Packgut fährt. Endseits des geschlossenen Bajonetts gelangt das Umreifungsmittel sodann in einen dem erstgenannten Pfosten gegenüberliegenden zweiten Pfosten und schließlich nach Passieren einer letzten Umreifungsmittel-Umlenkung in die obere horizontale Umreifungsmittelführung zum Verschlußaggregat.Strapping of a packaged product takes place in such a way that the strapping material brought in from the strapping material supply is introduced and advanced from the closure unit into a section of an upper horizontal strapping material guide in such a way that it arrives via a first strapping material deflection into a strapping material guide which forms a post of the strapping frame. From there, the strap, again via a strap deflection, arrives in a lower, horizontal strap guide, that moves as a tongue or 'bayonet' under palletized goods. At the end of the closed bayonet, the strapping material then arrives in a second post opposite the first-mentioned post and finally after passing a last deflecting material deflection into the upper horizontal strapping means guide to the closure unit.
Das vordere Umreifungsmittelende wird in einer Klemmvorrichtung des Verschlußaggregat festgehalten. Nun fährt die Pressplatte auf das Packgut herunter und komprimiert es. Wird jetzt das Umreifungsmittel in Richtung des Umreifungsmittelvorrats zurückgezogen, schält sich das das Packgut ringförmig umgebende Umreifungsmittel aus den Umreifungsmittelführungen heraus und spannt sich um das Packgut. Daraufhin verschweißt das Verschlußaggregat die sich in seinem Wirkbereich überlappenden Umreifungsmittelabschnitte und trennt das Umreifungsmittel auf der zum Umreifungsmittelvorrat führenden Seite ab. Auf diese Weise ist also nunmehr das zusammengepresste Packgut mit einer straffen Umreifung versehen.The front strapping end is held in a clamping device of the closure assembly. Now the press plate moves down onto the packaged goods and compresses them. If the strapping material is now pulled back in the direction of the strapping material supply, the strapping material surrounding the packaged product peels out of the strapping means guides and stretches around the packaged product. The sealing assembly then welds the strapping sections overlapping in its effective area and separates the strapping on the side leading to the stock of strapping. In this way, the compressed packaged goods are now provided with a tight strapping.
Sofern sich Packgut in der Umreifungsebene befindet und die Pressplatte mit dem Verschlußaggregat deshalb nicht heruntergefahren werden kann, ist aufgrund der Bauart solcher Vorrichtungen zumindest das der Pressplatte zugeordnete Verschlußaggregat (und auch der optionale Umreifungsmittelspeicher) in Höhen weit oberhalb der Reichweite der Bedienungsperson gelegen.If packaged goods are located in the strapping level and the press plate with the closure unit cannot therefore be shut down, at least the closure unit associated with the press plate (and also the optional strapping material store) is located at heights far above the reach of the operator due to the design of such devices.
Um nun bei auf das Packgut aufgesetzter Pressplatte die Handhabungen zum Zuführen von Umreifungsmittel zum Verschlußaggregat zu erleichtern, sei es nach Wechsel des Umreifungsmittelvorrats, sei es nach einem Umreifungsmittelriß oder im Anschluß an eine das Band betreffende andere Betriebsstörung, sieht eine bekannte Vorrichtung eine Umreifungsmittel-Überleitung in Gestalt eines rohrförmigen Kanals vor, deren seitlich außerhalb der Umreifungszone neben dem Umreifungsportal angeordnete Kanalmündung eine Umreifungsmittel-Einspeisung ausbildet, in die Umreifungsmittel von Hand ein- und zum Verschlußaggregat vorgeschoben werden kann, von dem das führende Umreifungsmittelende dann übernommen wird.Now, with the press plate placed on the packaged goods, the manipulations for feeding strapping material to facilitate the sealing assembly, whether after changing the strapping supply, whether after a tear in the strapping or following another malfunction affecting the strap, a known device provides a strapping transfer in the form of a tubular channel, the side of which outside the strapping zone next to the Strapping portal arranged channel mouth forms a strapping feed into which strapping can be manually inserted and advanced to the sealing unit, from which the leading end of the strapping is then taken over.
Diese Hilfseinrichtung erspart zwar mühsame Packgut-Handhabungen und manuelle Maschinensteuerungen, etwa um das Packgut aus der Umreifungszone zu entfernen, die Pressplatte abzusenken, das Verschlußaggregat mit neuem Umreifungsmittel zu versehen, die Pressplatte wieder hoch- und das Packgut erneut in Umreifungsposition zu fahren, doch ist das manuelle Zuführen von Umreifungsmittel in Überkopfhöhe allemal mühsam und verursacht zeitraubende Betriebsunterbrechungen.This auxiliary device saves tedious handling of the packaged goods and manual machine controls, for example to remove the packaged goods from the strapping zone, to lower the press plate, to provide the sealing unit with new strapping material, to raise the press plate again and to move the packaged goods back into the strapping position manual feeding of strapping overhead is always tedious and causes time-consuming business interruptions.
Der Erfindung liegt demzufolge die Aufgabe zugrunde, eine Vorrichtung der im Oberbegriff des Anspruchs 1 umrissenen Art anzugeben, bei der Betriebsunterbrechungen aufgrund erforderlicher Umreifungsmittelzufuhr zum Verschlußaggregat minimiert sind.The invention is therefore based on the object of specifying a device of the type outlined in the preamble of
Die Erfindung löst diese Aufgabe in Verbindung mit den Merkmalen des Oberbegriffs des Anspruchs 1 mit den im Kennzeichenteil dieses Anspruchs angegebenen Merkmalen. Damit ist die Möglichkeit geschaffen, in jeder beliebigen Betriebsposition der Maschine, also auch der Pressplatte und des Verschlußaggregats, letzterem einen neuen Umreifungsmittelanfang zuzuführen. Zudem besteht die Möglichkeit, dies zumindest halbautomatisch mit einer der Umreifungsmittel-Einspeisung zugeordneten Umreifungsmittel-Einschußvorrichtung zu bewerkstelligen, die - wie der Umreifungsmittelvorrat - bodennah angeordnet und deshalb problemlos zugänglich sein kann.The invention solves this problem in connection with the features of the preamble of
Außerdem vermeidet die Erfindung einen weiteren, der bekannten Vorrichtung anhaftenden Nachteil, der darin besteht, daß zwischen dem Umreifungsmittelvorrat und der auf einem wechselnd hohen Niveau gelegenen Mündung des freien Endes der Umreifungsmittel-Überleitung stets eine freie Umreifungsmittel-Sehne gespannt ist, die nicht nur durch unachtsam getragene Lasten beschädigt werden kann, sondern selbst auch eine Quelle für Verletzungen von Personen darstellt, die sich ihr nähern. Ferner muß im Bereich der Umreifungsmittelvorratstrommel eine zusätzliche Umreifungsmittel-Bevorratung installiert sein, um das bei Pressplattenabsenkungen überschüssige Band aufzunehmen.In addition, the invention avoids another disadvantage inherent in the known device, which is that between the supply of strapping material and the mouth of the free end of the strapping material transfer, which mouth is at an alternatingly high level, a free strapping material tendon is always stretched, not only by carelessly carried loads can be damaged, but also represents a source of injury to people who approach it. In addition, additional strapping stock must be installed in the area of the strapping stock drum to accommodate the excess tape when the press plate is lowered.

Eine insgesamt mit 10 bezeichnete Vorrichtung zum Umreifen von insbesondere kompressiblem Packgut 11 wie Wellpappelagen o.dgl. umfaßt zunächst einen bodennah aufgeständerten Umreifungsmittelvorrat 12 mit auf einer Trommel 13 aufgewickeltem Umreifungsmittel 14, insbesondere thermisch verschweißbarem Kunststoffband.An overall designated 10 device for strapping particularly compressible packaged
An Pfosten 15, 15' ist ein Querträger 16 in Richtung des Doppelpfeils 17 vertikal verfahrbar angeordnet. Der Querträger 16 bildet eine Pressplatte zum Komprimieren des Packguts 11 aus bzw. ist deren Bestandteil und lagert auf seiner Oberseite ein Aggregat 18, welches in später zu beschreibender Weise dem Transport des Umreifungsmittels 14 und vor allem der Ausbildung eines Umreifungsmittel-Verschlusses dient, weshalb das Aggregat künftig als Verschlußaggregat bezeichnet wird. Dem Verschlußaggregat 18 ist ein Umreifungsmittelspeicher 19 zugeordnet, der wie das Verschlußaggregat 18 bewegungseinheitlich und somit synchron mit der Pressplatte 16 angetrieben und beweglich geführt ist.On
Sowohl den Pfosten 15, 15' als auch dem Querträger 16 sind Umreifungsmittelführungen 20 bis 23 in Gestalt von geraden Kanälen bzw. Kanalabschnitten bekannter Bauart zugeordnet. Ebenfalls bekannt ist es, das portalartige Umreifungsmittelführungskanalgebilde 20 bis 23 dadurch zu einem in sich geschlossenen Rahmen auszubilden, daß bodenseitig eine das Packgut 11 oder die Palette, auf dem es lagert, unterfahrende Lanze bzw. ein Bajonett 24, das ebenfalls einen geradlinigen Umreifungsmittelführungskanal enthält, in Richtung des Pfeils 42 der Fig. 1 in die Position gemäß Fig. 2 bzw. 3 vorgeschoben wird.Both the
Damit das Umreifungsmittel 14 um das Packgut 11 geführt werden kann, muß es zunächst einmal dem Verschlußaggregat 18 zugeführt werden. Hierzu ist eine Umreifungsmittel-Einschußvorrichtung 25 bodennah sowie unmittelbar hinter dem Umreifungsmittelvorrat 12 vorgesehen, die mittels Umreifungsmittel-Förderrollen 26, von denen wenigstens eine maschinell angetrieben und die andere mit dieser zwangsgekuppelt ist, an der mit 27 bezeichneten Umreifungsmittel-Einspeisung das Umreifungsmittel 14 in eine Umreifungsmittelführung 28 vorschieben, die neben der pfostenartigen Umreifungsmittelführung 21 und zu ihr parallel angeordnet ist. Längs dieser Umreifungsmittelführung 28 ist eine Umreifungsmittel-Umlenkung 29 vertikalbeweglich angeordnet, die die Aufgabe hat, das Umreifungsmittel 14 jeweils an der Stelle, an der sich die Umreifungsmittel-Umlenkung 29 befindet, an eine horizontal angeordnete Umreifungsmittel-Überleitung 30 zu übergeben, die es zum Verschlußaggregat 18 weiterführt. Beim Ausführungsbeispiel geschieht dies durch den Umreifungsmittelspeicher 19 hindurch. Sobald das führende freie Umreifungsmittelende einen in Einschußrichtung nach dem Verschlußaggregat 18 befindlichen Schalter 31 kontaktiert, ist die Ausgangsstellung für eine erste Umreifung eines Packguts 11 erreicht - siehe Fig. 1.So that the strapping means 14 can be guided around the packaged
Senkrecht zur Zeichenebene wird nun zu umreifendes palettiertes oder palettenloses Packgut 11, z.B. mittels auf einem nicht dargestellten Rollengang in die Umreifungszone gefördert. Das Umreifungsmittel 14 wird sodann mittels Förderrollen 32 vorgeschoben, und zwar bezüglich Fig. 2 entgegen dem Uhrzeigersinn durch die Umreifungsmittelführung 20, 21, 24, 22, und 23 sowie durch die jeweils dazwischen in der Umreifungsmittel-Bahn befindlichen Umreifungsmittel-Umlenkungen 33 bis 36 vorgeschoben, bis das vordere Ende des Umreifungsmittels 14 wieder in das Verschlußaggregat 18 gelangt.Palletized or palletless packaged
Schon während dieses Herumführens des Umreifungsmittels oder sofort danach, senken sich Pressplatte 16, Verschlußaggregat 18 und Bandspeicher 19 nach unten auf die Oberseite des Packguts 11, welches nun je nach Beschaffenheit und Anforderung entsprechend stark komprimiert wird.Already during this guiding of the strapping means or immediately thereafter, the
Um sodann das Umreifungsmittel 14 um das komprimierte Packgut 11 zu straffen, wird der Antrieb der Umreifungsmittel-Förderrollen 32 reversiert, so daß diese das vom Umreifungsmittelvorrat 12 herangeführte Umreifungsmittel 14 zurückziehen, während das andere Umreifungsmittelende mittels einer Klemme am Verschlußaggregat 18 festgehalten wird. Aufgrund des Umreifungsmittelrückzugs wird das Umreifungsmittel 14 innen aus sämtlichen Umreifungsmittelführungen herausgezogen, die dazu in bekannter Weise ausgebildet sind, beispielsweise also flexible Lippen 39 wie in Fig. 6 gezeigt oder gegen Federwirkung öffnende Klappen aufweisen.In order to then tighten the strapping 14 around the compressed packaged
Die anfallende überschüssige Umreifungsmittelmenge wird währenddessen zurück in den Umreifungsmittelspeicher 19 gefördert und bildet hier einen in der Anfangsphase der nächsten Umreifung nutzbaren Vorrat aus. Um dies zu ermöglichen, ist der mit 40 bezeichneten Umreifungsmittel-Umlenkung im Umreifungsmittelspeicher 19 eine (z.B. mittels eines Hubmagneten 41 - Fig. 4) aussteuerbare Leitkurve 42 zugeordnet.The excess amount of strapping material that is produced is meanwhile conveyed back into the strapping
Sowohl beim ersten Einlegen von Umreifungsmittel 14 als auch nach Behebung einer das Umreifungsmittel in Mitleidenschaft ziehenden Betriebsstörung kann Umreifungsmittel 14 dem Verschlußaggregat 18 in jeder beliebigen Stellung der Vorrichtung 10 vom Boden aus zugeführt werden. Nach Entfernen eventuell in der Maschine befindlicher Umreifungsmittelreste wird der neue Umreifungsmittel-Anfang in die Einschußvorrichtung 25 gegeben, die die Vorrichtung 10 sodann automatisch mit dem Umreifungsmittel 14 lädt bis hin zur Übernahme durch die Umreifungsmittel-Förderrollen 32 am bzw. im Verschlußaggregat 18. Wesentlich ist, daß dazu erfindungsgemäß die zusätzliche Umreifungsmittel-Einführung 28 mit der Umreifungsmittel-Umlenkung 29 vorgesehen ist, die sich in Vertikalrichtung synchron mit der Umreifungsmittel-Überleitung 30 bewegt, die ihrerseits der Pressplatte 16 bewegungseinheitlich zugeordnet ist.Both when the
Wird die Pressplatte 16 gelüftet, kann ein weiteres Packgut oder dasselbe Packgut nach Vorschub ein weiteres Mal auf die beschriebene Art umreift werden. Für den letztgenannten Fall ist es bekannt, in paralleler Zuordnung zwei Umreifungsebenen E1 und E2 (Fig. 4) vorzusehen, wobei die beschriebenen Umreifungsmittelführungen und Umreifungsmittel-Umlenkungen entsprechend doppelt, Verschlußaggregat und ggf. ein Umreifungsmittelspeicher jedoch nur einmal vorhanden sind. Letztere sind deshalb quer zu den beiden Umreifungsebenen E1 und E2, also in bzw. entgegen Packgut-Transportrichtung, verfahrbar.If the
In diesem Fall ist die Umreifungsmittel-Überleitung 30 entsprechend der Aggregatverlagerung verstellbar eingerichtet. Beim Ausführungsbeispiel kann sie um die mit 37 und 38 bezeichneten Gelenke pendeln, wobei das Gelenk 37 raumfest der Umreifungsmittel-Umlenkung 29 vorgeordnet ist und das Gelenk 38 vom Verschlußaggregat 18 bzw. beim konkreten Ausführungsbeispiel vom Umreifungsmittelspeicher 19 mitgeführt wird. Folglich ist es nicht nur unwesentlich, in welcher Höhenstellung sich die Pressplatte 16 befindet, falls Umreifungsmittel 14 neu eingelegt werden muß, auch die jeweilige Querlage des Verschlußaggregats 18 bezüglich der Umreifungsebenen E1 und E2 ist beliebig.In this case, the strapping
Die zum zumindest halbautomatischen Einschuß neuen Umreifungsmittels 14 erfindungsgemäß vorgesehene Umreifungsmittelführung 28 kann mit einer der Umreifungsmittelführungen 21, 22 und die Umreifungsmittel-Umlenkung 29 kann mit einer der Umreifungsmittel-Umlenkungen 33, 36 gleichartig bzw. sogar identisch sein. Wie Fig. 7 zeigt, ist die Umreifungsmittelführung 28 dann lediglich gegenüber den den Umreifungsebenen E1 und E2 zugeordneten nach oben versetzt, da ja das Umreifungsmittel 14 oberhalb der Pressplatte 16 zuzuführen ist.The strapping means 28 provided according to the invention for at least semi-automatic insertion can be one of the strapping guides 21, 22 and the strapping means 29 can be identical or even identical to one of the strapping means 33, 36. As shown in FIG. 7, the strapping means guide 28 is then only offset upwards relative to the strapping levels E1 and E2, since the strapping means 14 is to be fed in above the
