Description

Technisches GebietTechnical field

Die Erfindung betrifft ein Verfahren zum Betreiben einer Ballenpresse und eine Ballenpresse zum Herstellen von verschnürten Ballen, insbesondere aus Abfallmaterial mit Folien oder folienähnlichem Material, z.B. Polyäthylenfolien.The invention relates to a method for operating a baler and a Baler for making tied bales, especially from Waste material with foils or foil-like material, e.g. Polyethylene films.

Stand der TechnikState of the art

Derartige Verfahren verwenden bekannte Ballenpressen mit in einem Preßkasten betriebenen Preßstempel, einem in den Preßkasten mündenden Füllschacht, einem sich an den Preßkasten anschließenden Preßkanal und einer zugeordneten Vorrichtung zum Umschnüren der Ballen, vorzugsweise mit Draht, in der Verschnürposition.Such methods use known balers in a press box operated ram, one in the press box filling chute, one adjoining the press box press channel and an associated Device for tying the bales, preferably with wire, in the Tie position.

Zum Herstellen von zu verschnürenden Ballen wird das Preßgut in den Preßkasten lose eingefüllt. Durch mehrere Hübe des Preßstempels, zwischen denen jeweils ein Nachfüllvorgang liegt, wird ein Ballen gepreßt, der nach dem letzten für seine Herstellung erforderlichen Hub bei vorgefahrenem Preßstempel umschnürt wird. Die Preßendstellung des Preßstempels - zugleich Verschnürposition während des Verschnürvorgangs - ist erforderlich, um den Ballen währenddessen an einer Expansion zu hindern, wobei der gepreßte Ballen andererseits gegen die im Preßkanal sich bereits befindlichen gepreßten verschnürten Ballen anliegt. Die an der Stirnfläche des Preßstempels verlaufenden Schnürnuten dienen dem Umschnürvorgang, nach dessen Beendigung der Preßstempel zurückgefahren wird, wobei der durch die Schnürnuten im Preßstempel geführte Draht am Ballen verbleibt und über die von den Schnürnuten ausgehenden, in die Stirnfläche des Preßstempels mündenden Austrittsschlitze vom Preßstempel freigegeben wird.To produce bales to be tied, the material to be pressed is placed in the press box filled in loosely. Through several strokes of the ram, between each one Refilling process, a bale is pressed, which after the last one for its Manufacturing required stroke is tied up when the ram moves forward. The Press end position of the ram - at the same time tying position during the Lacing operation - is required to keep the bale attached to one To prevent expansion, the pressed bale on the other hand against the im Press channel already existing compressed tied bales. The on the front surface of the press ram grooves serve the Strapping process, after the completion of which the ram is retracted, the wire guided through the lacing grooves in the press die remaining on the bale and over the emanating from the cord grooves into the face of the Press die opening exit slots is released from the press die.

Es wurde bereits eine derartige Vorrichtung zum Umschnüren von Ballen nach der DE-PS 26 28 540 bekannt, die das Ziel verfolgt, ohne komplizierte technische Mittel Drahtbrüche am verschnürten Ballen zu vermeiden. Such a device for strapping bales after the DE-PS 26 28 540 known that pursues the goal without complicated technical means Avoid wire breaks on the tied bale.

Allgemein besteht jedoch das Problem, daß verpreßte Ballen aus Abfallmaterial mit Folien oder folienähnlichem Material, z.B. Polyäthylenfolien in starkem Maße Lufteinschlüsse beinhalten. Diese bewirken nach dem Verschnüren besondere Expansionskräfte in den Ballen, die trotz der bisher geschaffenen Maßnahmen zum Reißen der Drahtverschnürungen führen können. Aus diesem Grund werden diese Ballen gegenwärtig nicht so hoch verdichtet, was einerseits zu komplizierten Regelungen im Drucksystem der Ballenpresse und andererseits zu einer für den Transport nachteiligen geringen Ballendichte führt.In general, however, there is the problem that compressed bales of waste material with Foils or foil-like material, e.g. Polyethylene films to a large extent Include air pockets. These have special effects after tying Expansion forces in the bales, which despite the measures created so far to Can cause the wire ties to tear. Because of this, they will Bales are not currently compacted so highly, which on the one hand is too complicated Regulations in the pressure system of the baler and on the other hand to one for the Transport disadvantageous low bale density leads.

Gemäß US-A-4 676 153 ist es bekannt, bereits verpreßte und gebundene Ballen von Heu oder anderem faserigen Material, erneut auf ungefähr die Hälfte ihres ursprünglichen Volumens zu pressen, dann mit Ballenbindegarn neu zu binden und danach für eine ausreichende Zeit in einer Dekompressionskammer so zu halten, daß die eingeschlossene Luft entweichen kann und die faserigen Materialeien etwas von ihrer Federkraft verlieren, bevor die erneut gebundenen Ballen uneingeschränkten Rückfederungsspannungen ausgesetzt werden.
Dadurch würden jedoch die Kosten für das Pressen und Verschnüren steigen, wenn man dieses Verfahren als Anregung zur Lösung des vorstehenden Problems heranzieht.According to US-A-4,676,153, it is known to repress pressed and bound bales of hay or other fibrous material to about half of their original volume, then to re-tie with bale twine and then for a sufficient time in a decompression chamber to hold in such a way that the trapped air can escape and the fibrous materials lose some of their spring force before the rebound bales are subjected to unrestricted spring-back stresses.
However, this would increase the cost of the pressing and tying if this method is used as a suggestion to solve the above problem.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu vermeiden und eine sichere Verschnürung der gepreßten Ballen zu gewährleisten.The invention has for its object to avoid these disadvantages and one to ensure secure tying of the pressed bales.

Erfindungsgemäß wird dies durch ein Verfahren nach dem Oberbegriff des Hauptanspruches gelöst, bei dem das Preßgut in einen Preßkasten lose eingefüllt wird, die Preßhübe über das Maß der Verschnürposition und zugleich einer eigentlichen Preßposition für die Verschnürung hinaus zu einer Preßposition, in der die Lufteinschlüsse weitgehend beseitigt sind, gefahren werden, dabei entsprechend dem Überhub der Preßposition mehr Draht nachgezogen und in einer Drahtlose vorgehalten und fixiert wird, danach mit dem bis in die Verschnürposition zurückfahrenden Preßstempel der gepreßte Ballen in der Drahtlose expandiert und schließlich in der Verschnürposition, die auch der eigentlichen Preßposition entspricht, die Verschnürung erfolgt, während der der Preßstempel gehalten wird.According to the invention, this is achieved by a method according to the preamble of Main claim solved, in which the material to be loosely filled in a press box is, the press strokes on the dimension of the tying position and at the same time one actual pressing position for the lacing to a pressing position in the the air inclusions are largely eliminated, driven accordingly after the overpressure of the pressing position, more wire is drawn and in a wireless is held up and fixed, then with the up to the tying position retracting ram of the pressed bale in the wireless expanded and finally in the tying position, which is also the actual pressing position corresponds, the tying takes place during which the ram is held.

Die Preßhübe werden soweit und sooft in die Preßposition gefahren, bis die Lufteinschlüsse, z.B. durch zerplatzende Folien, überwiegend beseitigt sind. In Ausbildung des erfindungsgemäßen Verfahrens erfolgt die Fixierung der Drahtlose in Abhängigkeit von der Expansion des gepreßten Ballens. Vorteilhaft ist es, die Preßposition in Abhängigkeit von einer bestimmten Dichte des Ballens einzustellen oder zu begrenzen. Somit wird verfahrensgemäß ein Ballen bereitgestellt, der die eingangs geschilderten Nachteile nicht mehr aufweist.The press strokes are moved as far and as often into the press position until the Air pockets, e.g. are mostly eliminated by bursting foils. In The method according to the invention is designed to fix the wireless in Dependence on the expansion of the pressed bale. It is advantageous that Adjust pressing position depending on a specific density of the bale or limit. According to the method, a bale is thus provided which no longer has the disadvantages described above.

Für die zugehörige erfindungsgemäße Ballenpresse sind sowohl ein Antrieb zum Fahren des Preßstempels als auch eine Steuereinrichtung für einen über das Maß der Verschnürposition hinaus fahrbaren Überhub des Preßstempels in eine Preßposition, Mittel für eine entsprechend dem Maß des Überhubs entstehende und fixierte Drahtlose, eine Auslösung des Rückhubes des Preßstempels in die Verschnürposition, die Sicherung der Verschnürposition und die Auslösung der Verschnürung mittels der Verschnüreinrichtung vorgesehen.For the associated baler according to the invention, both a drive for Driving the ram as well as a control device for one over the dimension the tying position also movable overstroke of the press ram in one Press position, means for an emerging and according to the degree of overstroke fixed wireless, triggering the return stroke of the ram in the Tying position, securing the tying position and triggering the Lacing provided by means of the tying device.

Nach Anspruch 6 kann der Überhub mittels des Antriebs für den Preßstempel durch einen verlängerten Hub des Kolbens mit Kolbenstange in einem Hydraulikzylinder, durch die Ausgestaltung der Preßplatte des Preßstempels, z.B. durch Verlängerung derselben, oder nach Anspruch 7 durch die Ausgestaltung des Preßkastens, z.B. Modifizierung desselben, einfach realisiert werden.According to claim 6, the overstroke by means of the drive for the ram an extended stroke of the piston with piston rod in a hydraulic cylinder, by the design of the press plate of the ram, e.g. by extension the same, or according to claim 7, by the configuration of the press box, e.g. Modification of the same, can be easily realized.

Zweckmäßig ist es, den Überhub des Preßstempels in der Preßposition in Abhängigkeit von der Dichte des Ballens zu begrenzen.It is useful to in the overstroke of the ram in the pressing position Limit depending on the density of the bale.

Weiterhin kann der Rückhub in Abhängigkeit von der Dichte des Ballens ausgelöst werden. Dafür können Steuermittel wie Druckmesser vorgesehen werden, die den Überhub und Rückhub in Abhängigkeit von der Dichte des Ballens koppeln.The return stroke can also be triggered depending on the density of the bale will. Control means such as pressure gauges can be provided for this purpose Couple overstroke and return stroke depending on the density of the bale.

    • Bester Weg zur Ausführung der ErfindungBest way to carry out the invention

    Die Erfindung wird an einem Ausführungsbeispiel anhand der Zeichnungen erläutert.The invention is explained using an exemplary embodiment with reference to the drawings.

    Gemäß Fig. 1 und 2 ist in einem Preßkasten einer Ballenpresse 1 mit rechteckigem Querschnitt ein Preßstempel 2 verschiebbar gelagert, der z.B. durch einen nicht näher bezeichneten Hydraulikzylinder angetrieben wird. Bei zurückgefahrenem Preßstempel 2 wird in Ballen 4 zu pressendes Abfallmaterial, z.B. mit Polyäthylenfolien durch einen oben in den Preßkasten 1 einmündenden Füllschacht 3 lose eingebracht. Zum Herstellen jedes Ballens 4 sind mehrere Arbeitshübe des Preßstempels 2 erforderlich. Im Preßkanal 5 sind bereits drei gepreßte Ballen 4 dargestellt, von denen der rechte und der mittlere schon mit Draht 9 verschnürt sind (nicht näher dargestellt).1 and 2 is in a press box a baler 1 with a rectangular Cross section a press ram 2 slidably mounted, e.g. by one not specified hydraulic cylinder is driven. With retracted Press stamp 2 is used in bales 4 to be pressed waste material, e.g. With Polyethylene films through a filling chute opening into the press box 1 at the top 3 introduced loosely. To produce each bale 4 are several working strokes Press 2 required. There are already three pressed bales 4 in the press channel 5 shown, of which the right and the middle are already tied with wire 9 (not shown in detail).

    Die Hübe des Preßstempels 2 werden über das Maß der Verschnürposition A hinaus mit einem Überhub A-B in die Preßposition B (Fig. 2) gefahren. Dabei wird diese Preßposition B weitgehend bestimmt von dem Anteil der in den Ballen eingeschlossenen Polyäthylenfolien. Wenn die Preßposition (Fig. 2) erreicht ist, sind die Lufteinschlüsse aus den zerplatzenden Polyäthylenfolien überwiegend beseitigt. Dafür kann bereits ein Überhub von ca. 100 mm ausreichend sein. Dabei wird oben und unten entsprechend Draht 9 durch den Überhub des Preßstempels 2 nachgeholt und eine nicht näher dargestellte Drahtlose fixiert. Danach wird der Preßstempel 2 in die Verschnürposition A (Fig. 1) zurückgefahren, wobei der Ballen 4 innerhalb der Drahtlose entsprechend expandieren kann. Die Verschnüreinrichtung 6 wird wirksam, indem mittels der Schnürnadeln 7 die unteren Drähte 9 durch die Schnürnuten 8 hochgeholt werden und die nicht dargestellte Verdrillung und Durchtrennung der verdrillten Drähte 9 erfolgt. The strokes of the press ram 2 are beyond the dimension of the tying position A. with an overstroke A-B in the pressing position B (Fig. 2). In doing so, this will Press position B largely determined by the proportion of the bale enclosed polyethylene films. When the pressing position (Fig. 2) is reached the air inclusions from the bursting polyethylene foils mostly eliminated. An overtravel of approx. 100 mm may be sufficient for this. Doing so will top and catched up below wire 9 by the overstroke of the ram 2 and fixed a wireless, not shown. Then the ram 2 in the tying position A (Fig. 1) moved back, the bale 4 within the Wireless can expand accordingly. The tying device 6 is effective, by means of the needles 7, the lower wires 9 through the Lacing grooves 8 are brought up and the twist and not shown The twisted wires 9 are severed.

    Anschließend wird der Preßstempel 2 zur Herstellung eines weiteren Ballens 4 zurückgefahren. Der so hergestellte Ballen 4 gewährleistet eine reißfeste Verschnürung, da die Ursachen einer die Verschnürung zerstörenden Expansion beseitigt sind.The press ram 2 is then used to produce a further bale 4 pulled back. The bale 4 thus produced ensures a tear-resistant Lacing because the causes of an expansion destroying the lacing are eliminated.

    Zur Realisierung des Überhubs A-B für eine Preßposition B sind auch andere Ausführungen, wie entsprechende Ausgestaltungen der Preßplatte des Preßstempels 2 oder des Preßkastens 1 möglich. Entscheidend ist die Gewährleistung eines Überhubes A-B.There are also others for realizing the overstroke A-B for a pressing position B. Designs, such as corresponding configurations of the press plate Press die 2 or press box 1 possible. It is crucial Ensuring an overstroke A-B.

    Zur Rationalisierung der Funktionsabläufe ist es zweckmäßig, eine geeignete Software für den Programmablauf einzusetzen, wobei die Endstellung der Preßposition B und die Auslösung des Rückhubes B-A in Abhängigkeit von der Dichte des Ballens mittels nicht dargestellter Druckmesser steuerbar ist.To rationalize the functional processes, it is advisable to use a suitable one Use software for the program sequence, the end position of the Press position B and the triggering of the return stroke B-A depending on the Density of the bale is controllable by means of a pressure meter, not shown.
