Definitions

  • the invention relates to a round bale press device for cardboard waste or the like.
  • packaging materials made of paper, cardboard or plastic are pressed and strapped after being used to form compact, transportable packages.
  • Known designs are batch-working box presses that are controlled and operated by hand and only achieve low outputs, or continuously working extrusion presses that work automatically, but can only be used economically when there is a large amount of material to be pressed.
  • Mechanical extrusion presses also interfere due to the loud running and the vibrations with each piston stroke.
  • Agricultural round balers are also already known (US Pat. Nos. 2,096,990 and 2,850,964), in which a soft, flexible mat made of intertwined hay or straw is continuously fed from below to the baling chamber by means of an upstream, separate holding device becomes. Due to the completely different working conditions and in particular the different material properties, arbitrary and independent means of feeding can be used.
  • the object of the invention is to provide an inexpensive, easy-to-use and largely automatic baling device for small and medium-sized pressings, in particular cardboard waste or the like, which runs quietly and has a high throughput capacity with a small space requirement.
  • the object is achieved in that the first belt section conveys steeply downwards and the second belt section steeply upwards that a funnel-shaped feed space is provided above the feed gap provided at the highest point of the press chamber is arranged that the first band section is pulled up so far above the feed gap that it forms a wall of the feed space, and that the upper end portion of the other wall of the feed space is designed as a feed table that is approximately at a right angle from the above
  • the feed gap of the extended portion of the belt section extends so that the material to be pressed fed in via the feed table is bent downwards in contact with the advanced belt section and pressed into the feed gap.
  • the pre-pressing of bulky goods into a flat layer, the simultaneous pressing into the feed gap and the tight rolling up of the pressed goods into a cylindrical round bale allow a high pressing performance with simple loading.
  • the press works completely bumpless and extremely quiet, the power requirement is low.
  • the strapping is possible with little construction effort through a largely automatic device.
  • it is only the arrangement of the feed area above the baling area in connection with the forced feed from top to bottom in the baling area that ensures that the round baler is not loaded with cardboard pieces and whole boxes and that the acceptance, pre-pressing and bale formation function properly.
  • the operator can easily push the good parts down from the feed table, supported by their own weight.
  • the bulging of the first belt section to expand the feed space when feeding larger quantities would block the flow of material if the belt section were arranged differently.
  • the arrangement of the feed area above the press area enables a reasonable machine size, a working height that is appropriate to the body and the ejection of the relatively heavy round bales near the ground.
  • the combination of the first conveyor belt of the round baler with the feed elements and the extension of the belt section to form a wall of the feed area not only simplify the drive, the overall construction effort and the maintenance work, but also reduce the susceptibility to operational disruptions that occur in several successive operations Conveyor elements can occur due to the escape of cardboard between two conveyor belts or conveyor rollers.
  • the unit of feed and press elements ensures a feed and roll speed of exactly the same size, which is essential in the case of material that is rigid in the feed direction: feed that is too slow would cause slippage in the press room, while feed that was too fast would create a jam in the feed gap.
  • a critical problem for the cardboard material to be processed is the start of every round bale formation.
  • the pressed material deflected by the swing-open second conveyor belt must be forced to roll up and not to the outside on the wide wedge side of the press room, where it was fed to step. This is ensured by the fact that the upper side of the empty press chamber, which tapers downwards in a wedge shape, is closed by a deflection roller which is driven in such a direction of rotation that the part of its circumference touching the round bale and the round bale at the point of contact have the same direction of movement .
  • the ease of use and the high throughput can be optimally achieved if the second wall of the feed space is designed as a fixed guide wall which extends from the feed table to the first conveyor belt and which delimits one side of the feed gap with an inlet edge which is in contact with the first belt section when the press chamber is empty.
  • a press housing 1 is constructed on two floor supports 2 and has two load-bearing side walls 3 and 4, a rear wall 5, an upper cover 6 and on the front side a front wall 7, to which hinges 8 link a bale removal flap 9 reaching to the floor is.

Description

Die Erfindung bezieht sich auf eine Rundballenpressvorrichtung für Kartonagenabfälle o. dgl. Mit Vorrichtungen dieser Art werden Verpackungsmittel aus Papier, Pappe oder Plastik nach ihrer Verwendung zu kompakten, transportfähigen Paketen gepresst und umschnürt. Bekannte Ausführungen sind absätzig arbeitende Kastenpressen, die von Hand gesteuert und bedient werden und nur geringe Leistungen erzielen, oder fortlaufend arbeitende Strangpressen, die zwar selbsttätig arbeiten, jedoch erst bei grossem Pressgutanfall wirtschaftlich einsetzbar sind. Mechanische Strangpressen stören darüber hinaus durch den lauten Lauf und durch die Erschütterungen bei jedem Kolbenhub.The invention relates to a round bale press device for cardboard waste or the like. With devices of this type, packaging materials made of paper, cardboard or plastic are pressed and strapped after being used to form compact, transportable packages. Known designs are batch-working box presses that are controlled and operated by hand and only achieve low outputs, or continuously working extrusion presses that work automatically, but can only be used economically when there is a large amount of material to be pressed. Mechanical extrusion presses also interfere due to the loud running and the vibrations with each piston stroke.

Es sind auch bereits landwirtschaftliche Rundballenpressen bekannt (US-PS 2 096 990 und US-PS 2 850 964), in welchen eine weiche, nachgiebige Matte aus in sich verflochtenem Heu oder Stroh durch eine vorgesetzte, separate Aufnahmevorrichtung von unten her kontinuierlich dem Pressraum zugeführt wird. Infolge der völlig anderen Arbeitsbedingungen und insbesondere der unterschiedlichen Materialbeschaffenheit können beliebige und unabhängige Mittel zum Zuführen angewendet werden.Agricultural round balers are also already known (US Pat. Nos. 2,096,990 and 2,850,964), in which a soft, flexible mat made of intertwined hay or straw is continuously fed from below to the baling chamber by means of an upstream, separate holding device becomes. Due to the completely different working conditions and in particular the different material properties, arbitrary and independent means of feeding can be used.

Die Aufgabe der Erfindung besteht darin, für kleinen und mittleren Pressgutanfall speziell von Kartonagenabfällen o. dgl. eine preisgünstige, leicht bedienbare und weitgehend selbsttätig arbeitende Ballenpressvorrichtung zu schaffen, die geräuscharm läuft und bei geringem Platzbedarf eine hohe Druchsatzleistung aufweist.The object of the invention is to provide an inexpensive, easy-to-use and largely automatic baling device for small and medium-sized pressings, in particular cardboard waste or the like, which runs quietly and has a high throughput capacity with a small space requirement.

Die Aufgabe wird, ausgehend von einer Ballenpressvorrichtung der im Oberbegriff des Anspruchs 1 genannten Art, dadurch gelöst, dass der erste Bandabschnitt steil nach unten und der zweite Bandabschnitt steil nach oben fördern, dass über dem an der höchsten Stelle des Pressraumes vorgesehenen Zuführspalt ein trichterförmiger Aufgaberaum angeordnet ist, dass der erste Bandabschnitt nach oben so weit über den Zuführspalt vorgezogen ist, dass er eine Wand des Aufgaberaumes bildet, und dass der obere Endabschnitt der anderen Wand des Aufgaberaumes als Aufgabetisch ausgebildet ist, der sich etwa im rechten Winkel von dem über den Zuführspalt vorgezogenen Teil des Bandabschnittes wegerstreckt, so dass das über den Aufgabetisch zugeführte Pressgut bei Berührung mit dem vorgezogenen Bandabschnitt nach unten vorgeknickt und in den Zuführspalt gedrückt wird.Starting from a baling device of the type mentioned in the preamble of claim 1, the object is achieved in that the first belt section conveys steeply downwards and the second belt section steeply upwards that a funnel-shaped feed space is provided above the feed gap provided at the highest point of the press chamber is arranged that the first band section is pulled up so far above the feed gap that it forms a wall of the feed space, and that the upper end portion of the other wall of the feed space is designed as a feed table that is approximately at a right angle from the above The feed gap of the extended portion of the belt section extends so that the material to be pressed fed in via the feed table is bent downwards in contact with the advanced belt section and pressed into the feed gap.

Das Vorpressen sperriger Güter zu einer flachen Schicht, das gleichzeitige Drücken in den Zuführspalt und das straffe Aufrollen des Pressgutes zu einem zylindrischen Rundballen erlauben eine hohe Pressleistung bei einfacher Beschickung. Die Presse arbeitet völlig stossfrei und äusserst leise, der Kraftbedarf ist gering. Die Umschnürung ist mit geringem Bauaufwand durch eine weitgehend selbsttätige Vorrichtung möglich. Jedoch gewährleistet erst die Anordnung des Aufgaberaumes über dem Pressraum in Verbindung mit der Zwangszuführung von oben nach unten in den Pressraum das absätzige Beschicken der Rundballenpresse mit Pappestücken und ganzen Kartons und eine störungsfreie Funktion von Annahme, Vorpressung und Ballenbildung. Die Gutsteile sind vom Bedienungsmann leicht vom Aufgabetisch nach unten drückbar, unterstützt vom Eigengewicht. Das Ausbeulen des ersten Bandabschnittes zur Ausweitung des Aufgaberaumes beim Zuführen grösserer Mengen würde bei anderer Anordnung des vorgezogenen Bandabschnittes den Gutsfluss blockieren. Ferner wird durch die Anordnung des Aufgaberaumes über dem Pressraum eine vertretbare Baugrösse der Maschine, eine körpergerechte Arbeitshöhe und das Auswerfen der relativ schweren Rundballen in Bodennähe ermöglicht. Ferner stellen die Kombination des ersten Förderbandes der Rundballenpresse mit den Zuführelementen und die Verlängerung des Bandabschnittes zur Bildung einer Wand des Aufgaberaumes nicht nur eine Vereinfachung des Antriebes, des gesamten Bauaufwandes und der Wartungsarbeiten dar, sondern vermindern auch die Anfälligkeit zu Betriebsstörungen, die bei mehreren aufeinanderfolgenden Förderelementen durch das Entweichen von Pappe zwischen zwei Förderbändern oder Förderwalzen auftreten können.The pre-pressing of bulky goods into a flat layer, the simultaneous pressing into the feed gap and the tight rolling up of the pressed goods into a cylindrical round bale allow a high pressing performance with simple loading. The press works completely bumpless and extremely quiet, the power requirement is low. The strapping is possible with little construction effort through a largely automatic device. However, it is only the arrangement of the feed area above the baling area in connection with the forced feed from top to bottom in the baling area that ensures that the round baler is not loaded with cardboard pieces and whole boxes and that the acceptance, pre-pressing and bale formation function properly. The operator can easily push the good parts down from the feed table, supported by their own weight. The bulging of the first belt section to expand the feed space when feeding larger quantities would block the flow of material if the belt section were arranged differently. Furthermore, the arrangement of the feed area above the press area enables a reasonable machine size, a working height that is appropriate to the body and the ejection of the relatively heavy round bales near the ground. Furthermore, the combination of the first conveyor belt of the round baler with the feed elements and the extension of the belt section to form a wall of the feed area not only simplify the drive, the overall construction effort and the maintenance work, but also reduce the susceptibility to operational disruptions that occur in several successive operations Conveyor elements can occur due to the escape of cardboard between two conveyor belts or conveyor rollers.

Darüber hinaus sichert die Einheit von Zuführ-und Presselementen eine genau gleichgrosse Einzugs- und Rollgeschwindigkeit, welche bei in Vorschubrichtung unnachgiebigem Material wesentlich ist: zu langsame Zuführung würde einen Schlupf im Pressraum verursachen, während zu schnelle Zuführung einen Stau im Einzugsspalt erzeugen würde.In addition, the unit of feed and press elements ensures a feed and roll speed of exactly the same size, which is essential in the case of material that is rigid in the feed direction: feed that is too slow would cause slippage in the press room, while feed that was too fast would create a jam in the feed gap.

Ein kritisches Problem stellt für das zu verarbeitende Kartonagenmaterial der Start zu jeder Rundballenbildung dar. Das vom aufschwenkbaren zweiten Förderband umgelenkte Pressgut muss mit Sicherheit gezwungen werden, sich aufzurollen und nicht etwa an der breiten Keilseite des Pressraumes, wo es zugeführt wurde, wieder nach aussen zu treten. Das wird dadurch gewährleistet, dass die oben liegende Seite des sich keilförmig nach unten verjüngenden leeren Pressraumes durch eine Umlenkwalze abgeschlossen ist, welche in einer solchen Drehrichtung angetrieben ist, dass der den Rundballen berührende Teil ihres Umfanges und der Rundballen an der Berührungsstelle die gleiche Bewegungsrichtung besitzen.A critical problem for the cardboard material to be processed is the start of every round bale formation. The pressed material deflected by the swing-open second conveyor belt must be forced to roll up and not to the outside on the wide wedge side of the press room, where it was fed to step. This is ensured by the fact that the upper side of the empty press chamber, which tapers downwards in a wedge shape, is closed by a deflection roller which is driven in such a direction of rotation that the part of its circumference touching the round bale and the round bale at the point of contact have the same direction of movement .

Nach einem weiteren Merkmal der Erfindung sind die leichte Bedienbarkeit und die hohe Durchsatzleistung optimal erzielbar, wenn die zweite Wand des Aufgaberaumes als feste Leitwand ausgebildet ist, die sich vom Aufgabetisch bis zum ersten Förderband erstreckt und die eine Seite des Zuführspaltes mit einer Einlaufkante begrenzt, an welcher bei leerem Pressraum der erste Bandabschnitt anliegt.According to a further feature of the invention, the ease of use and the high throughput can be optimally achieved if the second wall of the feed space is designed as a fixed guide wall which extends from the feed table to the first conveyor belt and which delimits one side of the feed gap with an inlet edge which is in contact with the first belt section when the press chamber is empty.

Weitere vorteilhafte Merkmale der Erfindung sind in den Unteransprüchen offenbart.Further advantageous features of the invention are disclosed in the subclaims.

Ein Beispiel des Erfindungsgegenstandes ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An example of the subject of the invention is shown in the drawing and is described in more detail below.

Ein Pressengehäuse 1 ist auf zwei Bodenträgern 2 aufgebaut und besitzt als äussere Begrenzungen zwei tragende Seitenwände 3 und 4, eine Rückwand 5, eine obere Abdeckung 6 und an der Vorderseite eine Vorderwand 7, an welche mit Scharnieren 8 eine bis zum Boden reichende Ballenentnahmeklappe 9 angelenkt ist. Über der Vorderwand 7 erstreckt sich zwischen den Seitenwänden 3 und 4 ein Aufgabetisch 10, an den sich ein Aufgaberaum 11 anschliesst.A press housing 1 is constructed on two floor supports 2 and has two load-bearing side walls 3 and 4, a rear wall 5, an upper cover 6 and on the front side a front wall 7, to which hinges 8 link a bale removal flap 9 reaching to the floor is. Above the front wall 7 extends between the side walls 3 and 4, a feed table 10, to which a feed space 11 connects.

Unter dem Aufgabetisch 10 und dem Aufgaberaum 11 liegt der Pressraum 12. Er wird im wesentlichen gebildet aus einem fest gelagerten ersten Förderband 13, einem aufschwenkbaren zweiten Förderband 14 und einer Umlenkwalze 15.The press space 12 is located below the feed table 10 and the feed space 11. It is essentially formed from a fixedly mounted first conveyor belt 13, a pivotable second conveyor belt 14 and a deflection roller 15.

Das erste Förderband 13 weist einen mit Mitnahmemitteln versehenen, endlosen Gurt 16 auf, welcher um eine untere, angetriebene Führungsrolle 17, drei rückwärtige Führungsrollen 18 und eine obere Spannrolle 19 geführt ist. Die Führungsrollen 17 und 18 sind in den Seitenwänden 3, 4 gelagert. Die Spannrollenwelle 20 ist durch einen Kreisbogenspalt 21 der Seitenwände 3, 4 nach aussen geführt und mit balligen Wälzlagern 88 in einem zweiarmigen Hebelpaar 22 gelagert, welches um eine Welle 23 schwenkbar an den Seitenwänden 3, 4 angebracht ist. Durch zwei Spannfedern 24 wird die Spannrolle 19 nach oben gespannt.The first conveyor belt 13 has an endless belt 16 provided with driving means, which is guided around a lower, driven guide roller 17, three rear guide rollers 18 and an upper tensioning roller 19. The guide rollers 17 and 18 are mounted in the side walls 3, 4. The tensioning roller shaft 20 is guided outwards through a circular arc gap 21 of the side walls 3, 4 and is mounted with spherical roller bearings 88 in a pair of two-armed levers 22 which is pivotably attached to the side walls 3, 4 about a shaft 23. The tensioning roller 19 is tensioned upwards by two tensioning springs 24.

Zwischen der Spannrolle 19 und der Führungsrolle 17 erstreckt sich ein erster Bandabschnitt 25. Er verläuft von oben her zunächst senkrecht bis zu einer Einlaufkante 26, an der er bei leerem Pressraum 12 anliegt. Von da an führt der Bandabschnitt 25 schräg abwärts bis zur Führungsrolle 17. Deren Antrieb in Pfeilrichtung 27 erfolgt durch ein Kettenrad 28 (Fig. 2).A first band section 25 extends between the tensioning roller 19 and the guide roller 17. It initially runs vertically from above up to an inlet edge 26, against which it rests when the pressing chamber 12 is empty. From then on, the belt section 25 leads obliquely downwards to the guide roller 17. The drive in the direction of arrow 27 is effected by a chain wheel 28 (FIG. 2).

Das zweite Förderband 14 (Fig. 1) ist im Pressengehäuse 1 um eine Schwenkachse 29 aufschwenkbar gelagert. Es besteht aus zwei Seitenwänden 30, zwischen welchen eine angetriebene Führungsrolle 31, eine Spannrolle 34 und eine Führungsrolle 35 gelagert sind. Die Spannrolle 34 wird durch Spannfedern 36 in Längsschlitzen 37 der Seitenwände 30 nach unten gespannt. Die Welle 38 der Führungsrolle 31 weist (Fig. 2) ein Stirnrad 39 auf, welches mit einem zweiten Stirnrad 40 kämmt, das koaxial mit einem Kettenrad 41 verbunden und auf der Schwenkachse 29 gelagert ist. Um die Führungsrollen 31, 34, 35 ist (Fig. 1) ein Gurt 54 geführt, der in einem zweiten Bandabschnitt 42 in Pfeilrichtung 43 aufwärts umläuft.The second conveyor belt 14 (FIG. 1) is mounted in the press housing 1 so as to be pivotable about a pivot axis 29. It consists of two side walls 30, between which a driven guide roller 31, a tension roller 34 and a guide roller 35 are mounted. The tensioning roller 34 is tensioned downwards by tensioning springs 36 in longitudinal slots 37 of the side walls 30. The shaft 38 of the guide roller 31 has (FIG. 2) a spur gear 39 which meshes with a second spur gear 40 which is connected coaxially to a sprocket 41 and is mounted on the pivot axis 29. A belt 54 is guided around the guide rollers 31, 34, 35 (FIG. 1) and rotates upwards in a second band section 42 in the direction of arrow 43.

Die Bandabschnitte 25, 42 bilden bei leerem Gerät den keilförmigen Pressraum 12, dessen Spitze unten zwischen den dicht aneinanderliegenden Führungsrollen 17 und 34 liegt und dessen breite Keilseite oben durch die Umlenkwalze 15 abgeschlossen ist, die ebenfalls in den aufklappbaren Seitenwänden 30 gelgart ist, und zwar dicht unter der Schwenkachse 29. Ihr Mantel besteht aus einem Gummiwerkstoff. Sie erhält ihren Antrieb durch einen Kettentrieb 44 von der Welle 38 und weist dieselbe Drehrichtung wie die Bandabschnitte 25 und 42 auf (Pfeil 45).When the device is empty, the belt sections 25, 42 form the wedge-shaped press chamber 12, the tip of which lies below between the closely spaced guide rollers 17 and 34 and whose broad wedge side is closed at the top by the deflecting roller 15, which is also gelgart in the hinged side walls 30, namely just below the swivel axis 29. Your jacket is made of a rubber material. It is driven by a chain drive 44 from the shaft 38 and has the same direction of rotation as the belt sections 25 and 42 (arrow 45).

Der Aufgaberaum 11, der sich über die gesamte Gehäusebreite erstreckt, wird durch den etwa senkrecht verlaufenden ersten Bandabschnitt 25 und durch eine schräg abfallende Leitwand 46 gebildet, die sich an den Aufgabetisch 10 anschliesst. Die Leitwand 46 führt bis an den ersten Bandabschnitt 25, wo sie eine leicht abgerundete Einlaufkante 26 bildet. Sie wird abgekantet weitergeführt bis an die Umlenkwalze 15, an der sie als Abstreifer 47 ausgebildet ist. Der die Einlaufkante 26 und den Abstreifer 47 bildende Teil der Leitwand 46 ist als getrenntes Werkstück ausgeführt und so an der Leitwand 46 angeschraubt, dass der Abstreifer 47 einstellbar ist. Zwischen der Einlaufkante 26 und dem ersten Bandabschnitt 25 ergibt sich ein Zuführspalt 48 für das im Aufgaberaum 11 vorgepresste Pressgut, der sich beim Zurückweichen des Bandabschnittes 25 vergrössert.The feed space 11, which extends over the entire width of the housing, is formed by the approximately vertically running first band section 25 and by a sloping guide wall 46, which adjoins the feed table 10. The guide wall 46 leads to the first band section 25, where it forms a slightly rounded inlet edge 26. It is folded further to the deflection roller 15, on which it is designed as a scraper 47. The part of the guide wall 46 which forms the leading edge 26 and the scraper 47 is designed as a separate workpiece and is screwed onto the guide wall 46 in such a way that the scraper 47 can be adjusted. Between the leading edge 26 and the first belt section 25 there is a feed gap 48 for the pressed material pre-pressed in the feed space 11, which increases when the belt section 25 withdraws.

Die Förderbänder 13 und 14 werden von einem Elektrogetriebemotor 49 angetrieben, der an einer Konsole 50 befestigt ist. Er weist ein Kettenrad 51 auf, von welchem eine Kette 52 um eine Umlenkrolle 53, dann mit ihrer Aussenseite um das Kettenrad 28 des ersten Förderbandes 13 und mit ihrer Innenseite um das Kettenrad 41 des zweiten Förderbandes 14 geführt ist. Dadurch übt die Kette 52, die in Pfeilrichtung 89 umläuft, auf das aufschwenkbare zweite Förderband 14 stets ein Drehmoment in der Richtung des Aufschwenkens 90 aus. Die Kette 52 wird durch ein Kettenspannrad 55, das auf einem Schwenkhebel 56 gelagert ist, dadurch leicht gespannt, dass eine der Spannfedern 24 nahe einem Schwenklager 57 des Schwenkhebels 56 an diesem angelenkt ist.The conveyor belts 13 and 14 are driven by an electric gear motor 49, which is attached to a bracket 50. It has a chain wheel 51, of which a chain 52 is guided around a deflection roller 53, then with its outside around the chain wheel 28 of the first conveyor belt 13 and with its inside around the chain wheel 41 of the second conveyor belt 14. As a result, the chain 52, which rotates in the direction of the arrow 89, always exerts a torque in the direction of the pivoting 90 on the pivotable second conveyor belt 14. The chain 52 is slightly tensioned by a chain tensioning wheel 55, which is mounted on a pivot lever 56, in that one of the tension springs 24 is articulated on a pivot bearing 57 of the pivot lever 56.

Das zweite Förderband 14, das während der Ballenbildung geschlossen ist, ist durch den Handhebel 58 aufklappbar (Fig. 3). Dieser ist mit einer Welle 59 in den Seitenwänden 3 und 4 gelagert und mit zwei Hebeln 60 fest verbunden, die mit zwei Koppelstangen 61 an Zapfen 62 der Seitenwände 30 angelenkt sind. Der Öffnungsmechanismus wird durch zwei zwischen den Hebeln 60 und dem Pressengehäuse 1 angebrachte Stossdämpfer 63 stabilisiert. Das Aufklappen wird erleichtert durch zwei Gewichtsausgleichsfedern 64. Jede von diesen Federn 64 ist einerseits am Pressengehäuse 1 und andererseits an einem zweiarmigen Hebel 65 angelenkt, der auf einem Bolzen 66 des Pressengehäuses 1 gelagert ist. Je eine Koppelstange 67 verbindet die zweiarmigen Hebel 65 mit dem Zapfen 62 der Seitenwände 30. An jedem der Hebel 60 ist ferner eine Stange 68 angelenkt, welche mit der Ballenentnahmeklappe 9 verbunden ist. Zum Schliessen des zweiten Förderbandes 14 und der Ballenentnahmeklappe 9 müssen die Koppelstangen 61 mit ihrem Gelenk 92 über eine Streckstellung geführt werden, welche in der Geraden der Gelenke 92, 59, 62 liegt (Fig. 2). Dadurch wird der feste Verschluss in Arbeitsstellung gesichert. Das in Aufschwenkrichtung 90 gerichtete Drehmoment des Kettenrades 41 unterstützt das Öffnen des Förderbandes 14 zu Beginn des Aufschwenkens; darüber hinaus verhindert dieses Drehmoment das unbeabsichtigte Schliessen des geöffneten Förderbandes 14 bei laufender Maschine.The second conveyor belt 14, which is closed during bale formation, can be opened by the hand lever 58 (FIG. 3). This is mounted with a shaft 59 in the side walls 3 and 4 and firmly connected with two levers 60 which are articulated with two coupling rods 61 on pins 62 of the side walls 30. The opening mechanism is stabilized by two shock absorbers 63 mounted between the levers 60 and the press housing 1. Unfolding is facilitated by two weight compensation springs 64. Each of these springs 64 is on the one hand on the press housing 1 and on the other hand on a pair Migen lever 65 is articulated, which is mounted on a pin 66 of the press housing 1. Each coupling rod 67 connects the two-armed lever 65 to the pin 62 of the side walls 30. A rod 68 is also articulated on each of the levers 60 and is connected to the bale removal flap 9. To close the second conveyor belt 14 and the bale removal flap 9, the coupling rods 61 must be guided with their joint 92 over a stretched position which lies in the straight line of the joints 92, 59, 62 (FIG. 2). This secures the fixed lock in the working position. The torque of the chain wheel 41 directed in the swing-open direction 90 supports the opening of the conveyor belt 14 at the start of the swing-open; in addition, this torque prevents the inadvertent closing of the open conveyor belt 14 while the machine is running.

Um das Auswerfen des fertigen Rundballens nicht durch eine Verklemmung zwischen den Seitenwänden 3, 4 des Pressengehäuses 1 zu erschweren, erstrecken sich die Seitenwände 30 des aufklappbaren zweiten Förderbandes 14 weist bis etwa in die Ballenmitte. Da sie vor dem Auswerfen aufgeschwenkt werden, ist die restliche Reibung zwischen den Seitenwänden 3 und 4 leicht vom ersten Bandabschnitt 25 zu überwinden, wobei dieser Bandabschnitt 25 beim Entspannen in Ausschwenkrichtung des Förderbandes 14 gesehen über die Seitenwände 3,4 hinaus vortritt.In order not to make it more difficult to eject the finished round bale due to a jamming between the side walls 3, 4 of the press housing 1, the side walls 30 of the hinged second conveyor belt 14 extend to approximately the middle of the bale. Since they are swung open before being ejected, the remaining friction between the side walls 3 and 4 can be easily overcome by the first belt section 25, this belt section 25 protruding beyond the side walls 3, 4 as seen in the swinging-out direction of the conveyor belt 14.

Oberhalb des Aufgaberaumes 11 ist eine Umschnürungsvorrichtung 69 (Fig. 3 und 4) angeordnet. Sie weist eine sich über die gesamte Pressengehäusebreite erstreckende Kehrgewindespindel 70 auf, welche mit ihrer Welle 23 in den Seitenwänden 3,4 gelagert ist und mit einem Kettentrieb 71 von der Spannrolle 19 ständig angetrieben wird. Auf der Kehrgewindespindel 70 ist ein Garnleitrogan 72 axial verschiebbar gelagert. Es ist als Hohlzylinderring ausgeführt, an dem ein Leitarm 73 über die Spannrolle 19 hinweg nach vorn geführt ist und mit einer Gamführungsöse 74 abschliesst, welche oberhalb des Zuführspaltes 48 des Aufgaberaumes 11 liegt.A strapping device 69 (FIGS. 3 and 4) is arranged above the feed space 11. It has a reversing thread spindle 70 which extends over the entire width of the press housing and which is mounted with its shaft 23 in the side walls 3, 4 and is constantly driven by a tensioning roller 19 with a chain drive 71. A yarn guide member 72 is axially displaceably mounted on the reversing thread spindle 70. It is designed as a hollow cylindrical ring, on which a guide arm 73 is guided forward over the tensioning roller 19 and ends with a thread guide eyelet 74, which lies above the feed gap 48 of the feed space 11.

Das Garnleitorgan 72 greift mit einem Führungsnocken in die Windungsnut 75 der Kehrgewindespindel 70, so dass die Garnführungsöse 74 über die Breite des Zuführspaltes 48 hin und her verschoben wird. Ein Garnstrang 76 wird aus einem Garnvorratsbehälter 77, der auf der Konsole 50 angebracht ist, durch eine Leitöse 78 zur Garnführungsöse 74 geführt; sein Garnende 79 hängt in Bereitstellung über dem Aufgaberaum 11 (Fig. 2).The yarn guide member 72 engages with a guide cam in the winding groove 75 of the reversing thread spindle 70, so that the yarn guide eyelet 74 is moved back and forth across the width of the feed gap 48. A yarn strand 76 is guided from a yarn storage container 77, which is attached to the bracket 50, through a guide eye 78 to the yarn guide eye 74; its yarn end 79 hangs in preparation over the feed space 11 (Fig. 2).

Unterhalb der Bewegungsbahn der Garnführungsöse 74 ist in der Maschinenmitte zwischen den Seitenwänden 3, 4 eine Garnabschneidevorrichtung 80 angeordnet. Sie weist zwei Kreischeibenmesser 81 auf, die freidrehend und einander überschneidend auf einer Lagerplatte 82 so gelagert sind, dass die Schneidkanten der beiden Kreisscheibenmesser 81 aneinanderliegen. Die Lagerplatte 82 ist mit einer Welle 83 in einer Konsole 84 schwenkbar gelagert. An der Welle 83 ist ein Handhebel 85 angebracht, mit welchem die Kreisscheibenmesser 81 in einer senkrechten Ruhestellung arretiert (Fig. 2) oder in eine Schneidstellung (Fig. 3) in die Bahn des Garnstranges 76, 79 einschwenkbar sind.Below the path of movement of the yarn guide eyelet 74, a yarn cutting device 80 is arranged in the middle of the machine between the side walls 3, 4. It has two circular disk knives 81, which are mounted freely rotating and overlapping one another on a bearing plate 82 such that the cutting edges of the two circular disk knives 81 abut one another. The bearing plate 82 is pivotally supported by a shaft 83 in a bracket 84. A hand lever 85 is attached to the shaft 83, with which the circular disk knives 81 can be locked in a vertical rest position (FIG. 2) or pivoted into a cutting position (FIG. 3) into the path of the yarn strand 76, 79.

Die Arbeitsweise der Ballenpressvorrichtung ist folgende: Die zu pressenden Kartonagenabfälle 86 werden bei laufender, geschlossener Maschine über den Aufgabetisch 10 gegen den etwa senkrecht verlaufenden, in Pfeilrichtung 27 angetriebenen ersten Bandabschnitt 25 und in den Aufgaberaum 11 geschoben. Dabei werden sie im Zuführspalt 48 flach gepresst und in den Pressraum 12 geführt. Der in Pfeilrichtung 43 angetriebene zweite Bandabschnitt 42 biegt und knickt das Pressgut um und führt es gegen die Umlenkwalze 15, von welcher es wieder nach unten geleitet wird, so dass zwischen den Bandabschnitten 25 und 42 eine Gutsrolle entsteht, die sich bei weiterer Pressgutzuführung zu einem Rundballen 87 (Fig. 6) vergrössert, wobei die Bandabschnitte 25 und 42 bis an die Führungsrollen 18, 35 zurückweichen. Dabei gestatten die balligen Wälzlager 88 dem Gurt 16 eine Anpassung auch an ungleichförmige Ballen.The operation of the baling device is as follows: The cardboard waste 86 to be pressed is pushed with the machine running and closed over the feed table 10 against the approximately vertically running first belt section 25 driven in the direction of arrow 27 and into the feed space 11. They are pressed flat in the feed gap 48 and guided into the pressing chamber 12. The second belt section 42 driven in the direction of arrow 43 bends and kinks the material to be pressed and guides it against the deflection roller 15, from which it is guided downwards again, so that a material roll is formed between the belt sections 25 and 42, which becomes a further material supply Round bales 87 (FIG. 6) enlarged, the belt sections 25 and 42 retracting as far as the guide rollers 18, 35. The spherical roller bearings 88 allow the belt 16 to be adapted even to non-uniform bales.

Wenn der Rundballen 87 die vorgesehene Grösse und Pressdichte erreicht hat, was durch ein elektrisches Strommessgerät 91 angezeigt wird, wird die Pressgutzuführung eingestellt und das Garnende 79 von Hand in den Zuführspalt 48 gezogen. Dabei wird das Garnende 79 zwischen , dem ersten Bandabschnitt 25 und der Ballenoberfläche erfasst und der Ballen 87 spiralig umschnürt. Nach ausreichender Umschnürung wird die Garnabschneidevorrichtung 80 mit dem Handhebel 85 in Arbeitsstellung geschwenkt, wodurch der Garnstrang 76 abgetrennt wird.When the round bale 87 has reached the intended size and baling density, which is indicated by an electric current measuring device 91, the baling material feed is stopped and the yarn end 79 is pulled into the feed gap 48 by hand. The yarn end 79 is grasped between the first band section 25 and the bale surface and the bale 87 spirally strapped. After sufficient tying, the yarn cutting device 80 is pivoted into the working position with the hand lever 85, as a result of which the yarn strand 76 is separated.

Durch Verschwenken des Handhebels 58 in seine Stellung nach Fig. 3 wird das zweite Förderband 14 aufgeklappt und die Ballenentnahmeklappe 9 geöffnet, wodurch der fertige Rundballen 87 durch das erste Förderband 13 nach vorn ausgeworfen wird. Nachdem das freiliegende Garnende unter eine Garnwindung geklemmt wurde, ist der Rundballen transportbereit.By pivoting the hand lever 58 into its position according to FIG. 3, the second conveyor belt 14 is opened and the bale removal flap 9 is opened, whereby the finished round bale 87 is ejected forward by the first conveyor belt 13. After the exposed end of the twine has been clamped under a twine, the round bale is ready for transport.
