Abstract
Description
Die Erfindung bezieht sich auf eine Bandmesserspaltmaschine, insbesondere zum Spalten von Blößen, mit einer der Messerschneide vorgeschalteten Zuführeinrichtung, bei der ein Transportspalt, der durch ein Unterbett und eine angetriebene Transportwalze begrenzt ist, und ein Zuführspalt, der durch ein Unterbett und eine angetriebene Zuführwalze begrenzt ist, dicht hintereinander angeordnet sind.The invention relates to a band knife splitting machine, especially for splitting nakedness, with a feeding device upstream of the knife edge, in the case of a transport nip that passes through a lower bed and a driven transport roller is limited, and a Feed gap that is driven by a lower bed and a Feed roller is limited, arranged closely one behind the other are.
Eine Bandmesserspaltmaschine dieser Art ist aus DE 197 14 592 A1 bekannt. Sowohl die Transportwalze als auch die Zuführwalze haben Zylinderform und wirken mit einem ebenen, im Ausführungsbeispiel nicht umlaufenden Unterbett zusammen. Durch die Trennung der Transportfunktion von der Zuführfunktion ist ein sehr genaues Spalten auch bei problemhaftem Spaltgut, wie es Blößen darstellen, möglich.A band knife splitting machine of this type is out DE 197 14 592 A1 known. Both the transport roller as the feed roller also has a cylindrical shape and cooperates a flat, not rotating in the embodiment Underblanket together. By separating the transport function of the feed function is a very accurate one Splitting even with problematic splitting material, such as nakedness represent, possible.
Der Erfindung liegt die Aufgabe zugrunde, das Einführen des Spaltguts zu erleichtern und die Spaltgenauigkeit noch zu verbessern. The invention has for its object the introduction to facilitate the splitting and the splitting accuracy still improve.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Transportwalze einen zu den Enden hin zunehmenden Durchmesser aufweist und aus mindestens zwei Teilen besteht, die drehfest und gelenkig miteinander verbunden und derart gelagert sind, daß ihre Mantellinie im Transportspalt eine zum Unterbett parallele Gerade bildet.This object is achieved in that the transport roller one increasing towards the ends Has a diameter and consists of at least two parts, which are non-rotatably and articulated together and are stored so that their surface line in Transport gap forms a straight line parallel to the lower bed.
Bei dieser Konstruktion ergeben sich bei der Transportwalze von der Mitte nach außen hin höhere Transportgeschwindigkeiten. Dies hat folgenden Vorteil: Üblicherweise wird eine Haut, z.B. eine Rindshaut, in der Bauchlinie aufgeschnitten und zum Durchlauf durch die Bandmesserspaltmaschine in die Ebene gebracht. Hierbei ist der Bauchbereich großflächiger und hat eine losere Struktur als die Rückenpartie. Wird eine solche Haut mit einer zylindrischen Transportwalze vorbewegt, so staut sich während des Transports der Bauchbereich an, während der mittlere Bereich längs der Rückenlinie dem Bauchbereich sozusagen voreilt. Dies kann dadurch kompensiert werden, daß die Haut im mittleren Bereich durch starkes Bremsen per Hand oder auch mit Bremsvorrichtung zurückgehalten wird. Verwendet man jedoch die erfindungsgemäße Transportwalze, ergibt sich aufgrund der Konizität im Außenbereich eine höhere Umfangsgeschwindigkeit. Da sich im Transportspalt kein oder nur ein geringer Schlupf ergibt, wird zwangsläufig die Haut im Randbereich mit Voreilung transportiert und dadurch quer zur Transportrichtung gestreckt. Hierdurch wird ein Stau des Bauchbereichs weitgehend vermieden und ein sehr genaues Spalten ermöglicht.This construction results in the transport roller higher transport speeds from the center outwards. This has the following advantage: Usually skin, e.g. a cowhide in which Cut open belly line and run through the Band knife splitting machine brought into the plane. in this connection the abdominal area is larger and has a looser one Structure than the back. Such a skin moved forward with a cylindrical transport roller, so the abdominal area builds up during transport, while the middle area along the back line to the Abdominal area, so to speak, advanced. This can be compensated that the skin in the middle area by heavy braking by hand or with a braking device is held back. However, if you use the Transport roller according to the invention results from the taper in the outer area a higher peripheral speed. Since there is no or only in the transport gap A little slip will result in the skin inevitably transported in the edge area with lead and thereby stretched across the transport direction. This will a congestion of the abdominal area largely avoided and a enables very precise splitting.
Günstig ist es, daß die Transportwalze aus zwei konusförmigen Teilen besteht. Dies ergibt einen einfachen Aufbau mit nur einer Kupplung in der Mitte der Transportwalze.It is favorable that the transport roller consists of two cone-shaped Sharing exists. This makes it easy Setup with only one coupling in the middle of the transport roller.
Von Vorteil ist es, daß zwei äußere Lager und ein mittleres Stützlager für die Transportwalze vorgesehen sind. Mit Hilfe des Stützlagers gelingt es auf einfache Weise, im Transportspalt die gewünschte gerade Mantellinie der Transportwalze aufrecht zu erhalten.It is advantageous that two outer bearings and a middle one Support bearing provided for the transport roller are. With the help of the support bearing, it is easy Way, in the transport gap the desired straight surface line of the transport roller.
Vorzugsweise ändert sich der Durchmesser der Transportwalze um mindestens 5%. Die besten Ergebnisse zeigten sich bei 15% und mehr. Als Beispiel sei eine Transportwalze angegeben, die in der Mitte einen Durchmesser von 76 mm und außen einen Durchmesser von 90 mm besitzt.The diameter of the transport roller preferably changes by at least 5%. The best results showed yourself at 15% and more. An example is a transport roller indicated that in the middle a diameter of 76 mm and outside has a diameter of 90 mm.
Empfehlenswert ist es, daß die Teile der Transportwalze über eine Bogenzahnverbindung, wie sie bekannterweise in der Bogenzahnkupplung verwendet wird, miteinander gekuppelt sind. Es kommen aber auch andere bekannte Gelenkkupplungen in Betracht.It is recommended that the parts of the transport roller via an arch tooth connection, as is known used in the curved tooth coupling, with each other are coupled. But there are also other known articulated couplings into consideration.
Sehr günstig ist es, daß die Umfangsgeschwindigkeit der Zuführwalze mindestens gleich der Umfangsgeschwindigkeit der Transportwalze im Bereich des größten Durchmesser ist. Hiermit ist sichergestellt, daß auch im Bauchbereich das dort schneller transportierte Material der Messerschneide so zugeführt wird, daß sich kein Stau und damit ein entsprechend gleichmäßigerer Schnitt ergibt.It is very favorable that the peripheral speed of the Feed roller at least equal to the peripheral speed the transport roller in the area of the largest diameter is. This ensures that also in Abdominal area the faster transported material there the knife edge is fed so that there is no Jam and thus a correspondingly more even cut results.
Weitere Vorteile bietet es, wenn die Transportwalze als Breitstreckwalze ausgebildet ist. Es erfolgt dann eine stärkere Ausbreitung des Spaltgutes quer zur Förderrichtung. There are further advantages if the transport roller as Spreader roll is formed. Then there is a Greater spreading of the fissile material transversely to the conveying direction.
Günstig ist es, daß das Unterbett des Transportspalts ein endloses Band aufweist, das um eine Unterwalze umgelenkt wird, die durch eine Andruckvorrichtung in Richtung auf die Transportwalze belastbar ist. Eine solche Zuführeinrichtung mit bewegtem Unterbett empfiehlt sich immer dann gegenüber einem statischen Unterbett, wenn es sich um ein Spaltgut handelt, das aus histologischen und Körperform-Gründen.ähnliche Probleme beim Schneiden aufwirft wie ein geäschertes Hautmaterial, aber nicht dessen Gleiteigenschaften besitzt.It is favorable that the lower bed of the transport gap has an endless belt which is deflected around a lower roller is that by a pressure device in Direction on the transport roller is resilient. A recommends such a feeding device with a moving lower bed always against a static underblanket, if it is a split material that consists of histological and body shape reasons. similar problems poses like a flared skin material when cut, but does not have its sliding properties.
Insbesondere kann die Unterwalze von Hebeln getragen sein, an denen die Andruckvorrichtung in Form einer Kolben-Zylinder-Einheit angreift. Dies ergibt eine einfachen konstruktiven Aufbau.In particular, the lower roller can be carried by levers be on which the pressure device in the form of a Piston-cylinder unit attacks. This makes it simple constructive structure.

Die veranschaulichte Bandmesserspaltmaschine 1 weist
ein mit einer Messerschneide 2 versehenes Bandmesser 3
auf, das zwischen zwei Garnituren 4 und 5 senkrecht zur
Zeichenebene in Richtung des Pfeiles 6 umläuft. The illustrated band knife splitting machine 1 has
a
Der Messerschneide 2 ist ein Zuführspalt 7 vorgeschaltet,
der an der Oberseite durch eine angetrieben Zuführ-
oder Lehrwalze und an der Unterseite durch ein
elastisches Unterbett 9, hier bestehend aus einer Gliederwalze
10 und einer elastischen Walze 11, begrenzt
ist. Unmittelbar vor dem Zuführspalt 7 befindet sich
ein Transportspalt 12, der an der Oberseite durch eine
angetriebene Transportwalze 13 und an der Unterseite
durch ein elastisches Unterbett 14 begrenzt ist. Das
Unterbett weist ein Transportband 15, eine fest gelagerte
Walze 16 und eine der Transportwalze 13 gegenüberliegende
Unterwalze 17 auf, die an einem Ausleger
18 befestigt ist, der durch eine Andruckvorrichtung 19,
hier eine Kolben-Zylinder-Einheit, gegen die Transportwalze
13 drückbar ist. Statt des hier dargestellten umlaufenden
Unterbetts 14 für den Transportspalt 12 kann
auch ein nicht umlaufendes ebenes Unterbett verwendet
werden, wie dies aus der DE 197 14 592 A1 bekannt ist.
Das gleiche gilt auch für das umlaufende Unterbett 9 im
Zuführspalt. Ein Spaltgut 20, insbesondere eine Blöße,
wird über den Transportspalt 12 und den Zuführspalt 7
der Messerschneide 2 zugeführt.A
Wie Fig. 2 zeigt, besteht die Transportwalze 13 aus
zwei Teilen 21 und 22. Die beiden Teile sind in der
Mitte durch eine Gelenkkupplung 23, zum Beispiel eine
Bogenzahnkupplung, miteinander verbunden und in einem
Stützlager 24 gehalten. Der Antrieb erfolgt über ein
Außenlager 25 des ersten Teils 21. Das zweite Teil 22
ist in einem Außenlager 26 gehalten. Beide Teile 21 und
22 haben eine Konusform, bei der sich der Durchmesser
von der Mitte zu den Enden hin erweitert. Die Änderung
sollte mindestens 5% betragen, kann aber auch 10%, 15%
oder mehr betragen. Die beiden Teile 21 und 22 werden
durch das Stützlager so gehalten, daß die dem Unterbett
14 zugewandt Mantellinie eine Gerade bildet. Beide Teile
21 und 22 haben eine entgegengesetzt gerichtete Riffelung,
um den Kontakt mit dem Spaltgut 20 zu verbessern
und auch eine Breitstreckwirkung zu erzielen. Die
entgegengesetzt gerichteten Riffelungen 27 und 28 an
der Oberfläche der Zuführwalze 8 sind üblich.As shown in FIG. 2, the
Wird nun als Spaltgut 20 eine Blöße zugeführt, so ergibt
sich wegen der Konusform der Transportwalze 13 an
den Rändern des Spaltguts 20 eine größere Transportgeschwindigkeit
als in der Mitte. Hierdurch werden die
weicheren Bauchabschnitte mit Voreilung gegenüber dem
mittleren Rückenabschnitt zum Zuführspalt 7 transportiert.
Gleichzeitig mit der Vorwärtsbewegung (Pfeil 29)
erfolgt eine Breitstreckwirkung (Pfeil 30), die teils
auf die unterschiedliche Umfangsgeschwindigkeit und
teils auf die entgegengesetzt gerichtete Riffelung der
Transportwalze 13 und gegebenenfalls der Zuführwalze 8
zurückzuführen ist.If a bare material is now supplied as
Vorzugsweise ist dafür gesorgt, daß die Umfangsgeschwindigkeit
der Zuführwalze 8 mindestens gleich der
Umfangsgeschwindigkeit der Transportwalze 13 im Bereich
des größten Durchmessers ist. Die voreilenden Bauchpartien
werden daher sicher im Zuführspalt aufgenommen und
dann durch das Bandmesser mit großer Genauigkeit geschnitten.It is preferably ensured that the peripheral speed
