Abstract
Description
Gegenwärtiger Stand der Technik ist ein "millen" des Leders in Fässern oder Trommeln. Hierbei werden Lederstücke in sich drehenden Fässern weichgewalkt.The current state of the art is a "millen" of leather in barrels or drums. Here pieces of leather are in themselves rotating barrels soft-milled.
Auf dem Leder entsteht als Oberflächenstruktur das typische sogenannte "Millkorn".The typical surface structure is created on the leather so-called "mill grain".
Es ist ebenso bekannt, Leder in Stollmaschinen wie z. B. der "Molissa" von Svit oder der Vibrasoft von Kela im Durchlauf verfahren zwischen zwei elastischen Bändern weichzustollen. Hierbei entsteht kein typisches Millkorn.It is also known to use leather in stud machines such. B. the "Molissa" by Svit or Vibrasoft by Kela in the run method to softly roll between two elastic bands. There is no typical mill grain.
Das Millen in Fässern hat den Nachteil, daß man keine Klein serien nach Bedarf im Durchlaufverfahren millen kann, und daß keine Kleinteile nach dem Stanzen oder Zurichten mit gu tem Ergebnis gemillt werden können, da sich hier mangels Masse die Randbereiche des Leders nicht mehr umbiegen.The millen in barrels has the disadvantage that you don't have small ones series can be milled as required, and that no small parts after punching or dressing with gu result can be grilled because there is a lack of Do not bend the edges of the leather.
Stollmaschinen haben den Nachteil, daß kein typisches Mill korn auf der Narbenseite entsteht, und daß das Leder während des Stollens auf Zug beansprucht wird, was nur ein bedingtes Weichmachen zuläßt.Stud machines have the disadvantage that no typical mill grain occurs on the grain side, and that the leather during the tunnel is under tension, which is only a conditional Allows softening.
Die beanspruchte Millmaschine hat diese Nachteile nicht!
Das Leder lädt sich durch geeignete technische Maßnahmen in
gekräuselter oder gewellter Form mit Materialüberfluß ein
führen, was die Zugkräfte beim Millen im Leder mindert
(Staucheffekt)
Die Vorteile sind:The claimed milling machine does not have these disadvantages! The leather is loaded with suitable technical measures in a ruffled or corrugated form with an excess of material, which reduces the tensile forces when rolling in the leather (compression effect)
The advantages are:
- - optimale Weichheit- optimal softness
- - Anwendungsmöglichkeit im Durchlaufverfahren- Possible application in Continuous process
- - Nachmillen oder Zwischenmillen vor Weiterverarbeitung- Post-mothers or intermediate mothers before further processing
- - sofortige Verfügbarkeit des ge millten Leders- Immediate availability of the ge millten leather
- - gute Millwirkung auch im Randbereich von Kleinlederteilen- Good mill effect also in the edge area of small leather parts
Die Millmaschine kann so gestaltet werden, daß die Millwirkung durch Veränderung der Achsabstände der Millwalzen beeinflußt werden kann. Ebenso können dadurch verschiedene Lederdicken berücksichtigt werden.The mill machine can be designed so that the mill effect influenced by changing the center distances of the mill rolls can be. Different leather thicknesses can also be created be taken into account.
Die Maschine lädt sich sowohl im Durchlaufverfahren, als auch im Vor- und Rückwärtsbetrieb (doppelter Millvorgang bei gleicher Millwellenzahl) anwenden.The machine loads both in a continuous process and in Forward and reverse operation (double mill process with the same Apply Millwave Number).
Durch axialen oder linearen Versatz der Millwalzen kann eine höhere Gleichmäßigkeit erreicht werden.Axial or linear misalignment of the mill rolls can result in a higher uniformity can be achieved.
Die Anzahl der Millwalzen ist beliebig. The number of mill rolls is arbitrary.
Fig. 1 Excentermillwalzenpaar ohne elastisches Transportband. Eine Ausführung von Fig. 1 mit elastischen Transportbän dern ist möglich. (Der Antrieb wurde aus Gründen der Übersichtlichkeit weggelassen.) Fig. 1 pair of eccentric rollers without elastic conveyor belt. An embodiment of Fig. 1 with elastic transport bands is possible. (The drive has been omitted for reasons of clarity.)
Fig. 2 Taumelscheibenexcenter- Millwalzenpaar ohne elastisches Transportband. Eine Ausführung von Fig. 2 mit elastischen Transportbän dern ist möglich. Fig. 2 swashplate eccentric mill roller pair without elastic conveyor belt. An embodiment of Fig. 2 with elastic transport bands is possible.
Fig. 3 Ausführung mit fünf Transportband- Umlenkwalzen und sechs Millwalzen. Der Achsabstand der Millwalzen kann veränderbar sein. Er wurde aus Gründen der Übersichtlichkeit im Verhält nis zu anderen Zeichnungsteilen in Fig. 3 vergrößert dargestellt. Fig. 3 version with five conveyor belt deflection rollers and six mill rollers. The center distance of the mill rolls can be changeable. It was shown enlarged for the sake of clarity in relation to other drawing parts in Fig. 3.
Es zeigt
Pos.: 1 + 3 + 5 = Umlenkwalzen oberes Transportband
Pos.: 2 + 4 = Umlenkwalzen unteres Transportband
Pos.: 6 bis 11 = Millwalzen
Pos.: 12 = unteres elastisches Transportband
Pos.: 13 = oberes elastisches TransportbandIt shows
Pos .: 1 + 3 + 5 = deflection rollers upper conveyor belt
Pos .: 2 + 4 = deflection rollers lower conveyor belt
Pos .: 6 to 11 = mill rolls
Pos .: 12 = lower elastic conveyor belt
Pos .: 13 = upper elastic conveyor belt
Es ergeben sich folgende Millstellen:
Nr. 1: zwischen Pos. 7 und 8
Nr. 2: zwischen Pos. 8 und 11
Nr. 3: zwischen Pos. 10 und 11
Nr. 4: zwischen Pos. 10 und 7
Nr. 5: zwischen Pos. 7 und 6
Nr. 6: zwischen Pos. 6 und 9
Nr. 7: zwischen Pos. 10 und 9 The following mill points result:
No. 1: between items 7 and 8
No. 2: between items 8 and 11
No. 3: between items 10 and 11
No. 4: between pos. 10 and 7
No. 5: between items 7 and 6
No. 6: between items 6 and 9
No. 7: between items 10 and 9
Erläuterung zu Fig. 4:
Pos. 1 = Excenter 1; Pos. 2 = Excenter 2;
P1 = Punkt 1
P2 = Punkt 2 Explanation of Fig. 4:
Pos. 1 = eccentric 1 ; Pos. 2 = eccentric 2 ;
P1 = point 1
P2 = point 2
Beim Drehen der beiden Excenternachbarn Pos. 1 und 2 um die gemeinsame Wellenachse auf 180° verschiebt sich Punkt 1 von Pos. 1 auf der linearen Ebene A-B an die Stelle von Punkt 1′. Der ursprüngliche Punkt 2 von Pos. 2 verschiebt sich auf Punkt 2′.When rotating the two eccentric neighbors items 1 and 2 around the common shaft axis to 180 °, item 1 moves from item 1 on the linear plane AB to the position of item 1 '. The original point 2 of item 2 shifts to point 2 '.
Die Punkte P1 und P2 der Excenter Pos. 1 und Pos. 2 überholen sich also jeweils nach einer halben Umdrehung der Millwelle gegenseitig auf der linearen Transportebene A-B um den Ab stand der gemeinsamen Exzentrizität.The points P1 and P2 of the eccentric pos. 1 and pos. 2 overtake each other after half a revolution of the mill shaft on the linear transport plane AB by the amount of the common eccentricity.
Es tritt jeweils ein Hin- und Hereffekt zwischen einem Ex center und dem um 180° versetzten Excenternachbarn auf der linearen Transportebene A-B ein, der einen Mill- oder Walk effekt begründet.There is a back and forth effect between an ex center and the eccentric neighbor on the linear transport plane A-B, which is a mill or walk justified effect.
