Abstract

A method for disposing of flat problem material, in particular stamped grids (4) which remain after the stamping-out of adhesive labels. The problem material is guided through a longitudinal cutter (6) and cut up into longitudinal strips. The longitudinal strips are guided through a tube (20) to a transverse cutter (24) and cut up to form granulated material. The granulated material is fed to a disposal point, in particular to a refuse-incineration plant. An apparatus for carrying out the method has pairs of cooperating knife discs (14) rotatable about an axis transverse to the conveying direction. Arranged in front of the said knife discs (14) are conveying rollers. The transverse cutter (24) has knives (28) which are attached to a drive shaft (16) arranged transversely to the conveying direction, air passage openings (36) for the conveying air being provided between the knives and the drive shaft and outside the knives. For the purpose of applying a liquid lubricant, in particular oil, use is made of a brush roller (12.5) which cooperates with a stripper (12.7) in such a manner that the bristles led through under the stripper and bent over throw the lubricant onto the side, coated with glue, of the problem material when they resile. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Entsorgen von flächenhaftem Problemmaterial. Hierunter soll Material verstanden werden, das nicht ohne weiteres wiederverwendet werden kann und dessen Entsorgung Probleme bereitet. Ein Beispiel hierfür sind Stanzgitter, die nach dem Ausstanzen von Klebeetiketten übrig bleiben. Diese Stanzgitter haben zusammenhängende Längs- und Querstege. Sie bestehen aus Papier, Karton, Aluminium- oder Kunststoff-Folie, sind in jedem Falle aber beschichtet mit einem selbstklebenden Stoff. Bisher können die Stanzgitter, zu Rollen aufgewickelt, nur auf eine Mülldeponie gebracht werden. Die Entsorgung auf Deponien ist teuer und wird für Gewerbemüll dieser Art künftig nur noch eingeschränkt möglich sein.The invention relates to a method and an apparatus for the disposal of flat problem material. This is to be understood as material that cannot be easily reused and whose disposal causes problems. An example of this are lead frames that are left over after stamping out adhesive labels. These lead frames have coherent longitudinal and transverse webs. They consist of paper, cardboard, aluminum or plastic film, but are always coated with a self-adhesive material. So far, the lead frames, wound up in rolls, can only be brought to a landfill. Disposal at landfills is expensive and will only be possible to a limited extent for commercial waste of this type in the future.

Dagegen brauchen Müll-Heizkraftwerke energiereiches Material zur Erhaltung eines Stützfeuers während der Nachtstunden. Für eine thermische Wiederverwertung dort ist das Material zwar wegen seines hohen Energiegehalts interessant, jedoch nicht in der Form von schlecht brennbaren, massiv verklebten Rollen.In contrast, waste-to-energy plants need high-energy material to maintain a support fire during the night. The material is interesting for thermal recycling there because of its high energy content, but not in the form of poorly flammable, solidly bonded rolls.

Durch die Erfindung soll auch Problemmaterial anderer Art entsorgt werden können, insbesondere ganz allgemein, Verbundwerkstoffe.Problem materials of a different kind should also be able to be disposed of by the invention, in particular very generally, composite materials.

Aufgabe der Erfindung ist es daher, ein Verfahren und eine Vorrichtung zu schaffen, die Problem-Material derart umwandeln, daß es ohne weiteres einer thermischen Verwertung, insbesondere in einem Müll-Heizkraftwerk zugeführt, werden kann. Außerdem soll die Handhabung des Materials am Entstehungsort automatisiert werden.The object of the invention is therefore to provide a method and a device which convert problem material in such a way that it can be readily used for thermal recycling, in particular in a waste-to-energy plant. In addition, the handling of the material at the point of origin should be automated.

Eine Weiterverarbeitung der Stanzgitter wird durch den an ihnen noch haftenden Selbstkleber erschwert. Dadurch bleiben Stanzgitter und ihre Teile normalerweise in Verarbeitungsmaschinen hängen.Further processing of the lead frames is made more difficult by the self-adhesive still adhering to them. As a result, leadframes and their parts usually get caught in processing machines.

Durch die vorliegende Erfindung sollen die oben geschilderten Probleme gelöst werden.The present invention is intended to solve the problems described above.

Dies geschieht gemäß Anspruch 1 und 7 in mehreren Verfahrensschritten, wozu zunächst gehört, daß das Material durch einen Längsschneider geführt und von diesem in Längsstreifen zerschnitten wird. Die Längsstreifen werden dann durch ein Rohr zu einem Querschneider gefördert, der sie zu Granulat zerschneidet, und das Granulat wird einer Entsorgungsstelle insbesondere einer Müllverbrennungsanlage (auch einem Müll-Heizkraftwerk) zugeführt.This is done according to claims 1 and 7 in several process steps, including first of all that the material is passed through a slitter and cut into longitudinal strips by this. The longitudinal strips are then conveyed through a pipe to a cross cutter, which cuts them into granules, and the granules are fed to a disposal point, in particular a waste incineration plant (also a waste heating plant).

Die Breite der Längsstreifen läßt sich hierbei so wählen, daß ein anschließender Transport durch Luftströmung in einem Rohr möglich ist. Das schließlich entstehnde Granulat läßt sich in einem zentralen Entsorgungssystem automatisiert transportieren und kann auch einer Müllverbrennungsanlage zugeführt werden, da sein Verhältnis Oberfläche/Rauminhalt besonders hoch ist, ganz im Gegensatz zu verklebten Rollen aufgewickelter Stanzgitter, bei den die Flammen praktisch keinen Zugang zum Inneren haben. Das erwähnte zahlenmäßig große Verhältnis ist also eine wesentliche Voraussetzung für eine Verbrennung ohne Zusatz von weiteren Brennstoffen.The width of the longitudinal strips can be selected so that subsequent transport by air flow in a tube is possible. The resulting granulate can be transported automatically in a central disposal system and can also be sent to a waste incineration plant, since its surface / space ratio is particularly high, in contrast to glued rolls of lead frames, where the flames have practically no access to the interior. The large numerical ratio mentioned is therefore an essential prerequisite for combustion without the addition of further fuels.

WeiterbildungenTraining

der Erfindung ergeben sich aus den Unteransprüchen.the invention emerge from the subclaims.

Eine Weiterverarbeitung von Problem-Material mit anhaftendem Kleber, insbesondere Stanzgittern, wird durch den an ihnen haftenden Kleber erschwert. Dadurch bleiben Stanzgitter und ihre Teile normalerweise in Verarbeitungsmaschinen, z. B. einer Zerkleinerungsanlage, hängen. Dies läßt sich durch Beschichtung des Problem-Materials mit einem Gleitmittel, insbesondere Öl, verhindern.Further processing of problem material with adhering adhesive, in particular lead frames, is made more difficult by the adhesive adhering to them. As a result, leadframes and their parts normally remain in processing machines, e.g. B. a crushing plant hang. This can be prevented by coating the problem material with a lubricant, especially oil.

Nach dem Längsschneiden werden die verbleibenden Längsstreifen vorzugsweise von einem Luftstrom, durch ein Rohr vom Längs- zum Querschneider gefördert. Die Breite der Längsstreifen läßt sich so wählen, daß bei ihrem anschließenden Transport in einem Rohr durch Luftströmung verbleibende Querstege an mindestens einem Längssteg hängen bleiben.After the longitudinal cutting, the remaining longitudinal strips are conveyed, preferably by an air stream, through a tube from the slitter to the cross cutter. The width of the longitudinal strips can be selected so that when they are subsequently transported in a tube, cross webs remaining due to air flow get caught on at least one longitudinal web.

Eine Vorrichtung zur Durchführung des Verfahrens enthält außer Messern für das Längs- und Querschneiden vor allem eine Auftragsstation, die zum Abgeben des Gleitmittels, insbesondere Öls, dient.A device for carrying out the method contains, in addition to knives for the longitudinal and transverse cutting, above all an application station which serves to dispense the lubricant, in particular oil.

Durch weitere Rohre läßt sich nach dem Querschneider das Granulat, wiederum von einem Luftstrom, einem Preß-Container zuführen, wodurch das Transportvolumen verringert wird.The granules can be fed to a press container, again from an air stream, by means of further pipes, whereby the transport volume is reduced.

Figur 1 zeigt zwei Druckmaschinen 2, die Etiketten innerhalb einer von einer Rolle ablaufenden Bahn bedrucken und die Etiketten ausstanzen. Ein dann verbleibendes Stanzgitter 4 von z. B. 50 cm Breite wird nach oben abgezogen. Es waren nebeneinander je drei Etiketten bedruckt worden, so daß das Stanzgitter jeweils nebeneinander drei etwa rechteckige Öffnungen hat. Das Stanzgitter besteht aus vier Längsstegen (lotrecht) und dazu rechtwinklig angeordneten Querstegen. Die Stanzgitter 4 werden je einem Längsschneider 6 zugeführt, wie er perspektivisch in Figur 2 dargestellt ist.FIG. 1 shows two printing presses 2, which print labels within a web running from a roll and punch out the labels. A then remaining lead frame 4 of z. B. 50 cm width is subtracted upwards. Three labels were printed next to each other, so that the lead frame has three approximately rectangular openings next to each other. The leadframe consists of four longitudinal bars (perpendicular) and cross bars arranged at right angles to them. The lead frames 4 are each fed to a slitter 6, as shown in perspective in FIG. 2.

Der Längsschneider hat zusammenwirkende Paare von Förderwalzen 8, die das Stanzgitter in Richtung des Pfeils 10 einziehen, und zwar an einer Auftragsstation 12 vorbei, die auf die untere Seite der Stanzgitter berührungsfrei ein Gleitmittel, insbesondere Öl aufträgt. Die Auftragsstation hat unten einen flachen Vorratsbehälter 12.1, der das flüssige Gleitmittel 12.2 aufnimmt. Eine frei drehbar gelagerte Dosierwalze 12.3 taucht teilweise in das Gleitmittel ein, nimmt bei ihrer Umdrehung Gleitmittel an ihrer Oberfläche mit und übergibt es an eine mit radialen, elastischen Borsten versehene Walze (Bürstenwalze 12.5). Die Bürstenwalze wird in Richtung eines Pfeils 12.6 angetrieben. Etwas oberhalb der Mitte der Bürstenwalze ist ein über ihre ganze Länge verlaufender Abstreifer 12.7 angeordnet, der so dicht an die Bürstenwalze heranragt, daß die Borsten bei der Rotation der Bürstenwalze umgebogen werden und dann nach oben zurückschnellen. Dabei wird das an den Borsten haftende Gleitmittel in feinen Tröpfchen gegen die untere Fläche eines darüber entlanggezogenen Stanzgitters geschleudert. Das Gleitmittel wird also ohne Berührung zwischen Borsten und Stanzgitter aufgebracht.The slitter has cooperating pairs of conveyor rollers 8, which pull the lead frame in the direction of arrow 10, past an application station 12, which applies a lubricant, in particular oil, to the lower side of the lead frame without contact. The application station has a flat storage container 12.1 below, which holds the liquid lubricant 12.2. A freely rotatably mounted metering roller 12.3 is partially immersed in the lubricant, takes along lubricant on its surface during its rotation and transfers it to a roller provided with radial, elastic bristles (brush roller 12.5). The brush roller is driven in the direction of an arrow 12.6. Somewhat above the center of the brush roller is a scraper 12.7 which runs over its entire length and which projects so close to the brush roller that the bristles are bent as the brush roller rotates and then snap back upwards. Doing so the lubricant adhering to the bristles is thrown in fine droplets against the lower surface of a lead frame drawn over it. The lubricant is therefore applied without contact between the bristles and the lead frame.

Unter Umständen läßt sich das Gleitmittel auf einfachere Weise auftragen, nämlich durch Sprühen oder Walzen.The lubricant may be easier to apply, such as spraying or rolling.

Von den Förderwalzen 8 werden die Stanzgitter zu Paaren zusammenwirkender, rotierender Messerscheiben 14 geschoben. Ein in Laufrichtung des Stanzgitters geführter Luftstrom wirkt hierbei unterstützend. Die Messerscheiben 14 sind in Richtung ihrer Antriebswelle verschiebbar und feststellbar. Man stellt sie so ein, daß sie von den die Querstege der Stanzgitter durchtrennen. Wünscht man keine einzelnen Querstegstücke, so läßt man zwischen zwei Längsstegen nur ein Messerscheibenpaar wirksam werden.The lead frames are pushed into pairs of interacting, rotating cutter disks 14 by the conveyor rollers 8. An air flow guided in the running direction of the lead frame acts as a support. The cutter disks 14 can be moved and locked in the direction of their drive shaft. They are set so that they cut through the crossbars of the lead frames. If you do not want individual crossbar pieces, only one pair of knife disks can be effective between two longitudinal webs.

Die nach dem Längsschneiden verbleibenden Längsstreifen und ggf. Abschnitte von Querstegen werden von einem Luftstrom in Richtung eines Pfeils 18 (Fig. 2) durch Rohre 20 (Fig. 1) mit einem Innendurchmesser von z. B. 20 cm gesaugt, und zwar von einem Gebläse 22. Das Material wird durch einen Querschneider 24 gesaugt.The longitudinal strips remaining after the longitudinal cutting and, if appropriate, sections of transverse webs are caused by an air flow in the direction of an arrow 18 (FIG. 2) through pipes 20 (FIG. 1) with an inner diameter of z. B. 20 cm sucked, by a fan 22. The material is sucked through a cross cutter 24.

Die Figuren 3 und 4 zeigen den Querschneider in zwei zueinander rechtwinkligen Schnitten, beide in Längsrichtung eines den Querschneider enthaltenden Rohres 26. Der Querschneider hat drei Messer 28, die unter gleichen Winkeln angeordnet und über Kreisscheiben 29 drehfest mit einer Antriebswelle 30 verbunden sind. Die Schneidkanten der Messer stehen schräg zur Achse und sind etwas auswärts gekrümmt, so daß sie innerhalb einer gedachten Zylinderfläche liegen. Die Längsstreifen werden in Richtung der Pfeile 32 in den Bereich der Messer 28 gesaugt. Von dem in Figur 3 und 4 untersten Messer werden die Streifen gegenüber einer achsparallelen Schneidkante 34 (Figur 4) in Stücke geschnitten. Zwischen den Messern und der Antriebswelle 30 verbleiben Durchläßöffnungen 36 für die Förderluft. Weitere Durchläßöffnungen für die Förderluft bestehen zwischen denjenigen Messern 28, die gerade nicht am Schneidprozeß beteiligt sind und der Innenwandung des Rohrs 26.FIGS. 3 and 4 show the cross cutter in two mutually perpendicular cuts, both in the longitudinal direction of a tube 26 containing the cross cutter. The cross cutter has three knives 28 which are arranged at the same angles and are connected in a rotationally fixed manner to a drive shaft 30 via circular disks 29. The cutting edges of the knives are at an angle to the axis and are curved slightly outwards so that they lie within an imaginary cylinder surface. The longitudinal strips are sucked in the direction of the arrows 32 into the area of the knives 28. 3 and 4, the strips are cut into pieces by an axially parallel cutting edge 34 (FIG. 4). Passage openings 36 for the conveying air remain between the knives and the drive shaft 30. Further passage openings for the conveying air exist between those knives 28 that are not currently involved in the cutting process and the inner wall of the tube 26.

In dem Querschneider nach Figur 3 und 4 entsteht Granulat, das durch ein Rohr 40 (Figur 1) vom Gebläse 22 angesaugt wird, das Gebläse durchläuft und dann über einen Zyklon 42 zum Luftabscheiden, eine Klimaschleuse 44 von einem weiteren Gebläse 46 durch ein Rohr 48 über einen Auffangbehälter 50 schließlich einer Presse 52 zugeführt wird. Diese preßt das Granulat in einen Preß-Container 54, der dann einer Entsorgungsstelle, insbesondere einem Müll-Heizkraftwerk zugeführt wird.In the cross cutter according to FIGS. 3 and 4, granulate is formed which is sucked in by the blower 22 through a pipe 40 (FIG. 1), passes through the blower and then via a cyclone 42 for air separation, a climate lock 44 from a further blower 46 through a pipe 48 is finally fed to a press 52 via a collecting container 50. This presses the granules into a press container 54, which is then fed to a disposal point, in particular a waste-to-energy plant.
