Description
Saumstreifenführung an Kreismessersaumscheren Die Erfindung bezieht sich auf eine Zuführung der beim Besäumen von Bandmaterial aus Stahl, Eisen und Metallen an Kreismessersaumscheren entstehenden Abfallsäume zu einer Zerhack- bzw. Zerkleinerungsvorrichtung für die Abfallsäume.Hemming strip guide on circular knife hemming shears The invention relates on a supply of when trimming strip material made of steel, iron and Metal scrap hems from circular knife hemming shears for a chopping or chopping process. Shredding device for the garbage hems.
Es ist an Kreismessersaumscheren bekannt, die Abfallsäume frei in den Arbeitsraum neben der Schere laufen zu lassen.. Der Arbeiter an der Schere wird durch die einen wirren Knäuel bildenden Abfallsäume in seiner Tätigkeit behindert und durch die scharfen Saumkanten gefährdet. Die Saumknäuel müssen laufend entfernt und durch besondere Vorrichtungen (z. B. Schrottwickelmaschinen) zusammengepreßt werden, ehe sie verwertet werden können. Dies erfordert weitere Arbeitskräfte. Eine weitere Art der Beseitigung der Abfallsäume besteht darin, diese auf einer über der Kreismessersaumschere angebrachten Trommel aufzuhaspeln.Circular knife hemming shears are known to free the waste hems in to run the work area next to the scissors .. The worker at the scissors will hampered in its activity by the garbage halls forming a tangled tangle and endangered by the sharp hem edges. The ball of hem must be removed continuously and pressed together by special devices (e.g. scrap winding machines) before they can be used. This requires more workers. One Another way of removing the garbage seams is to do this on one over the drum attached to the circular knife trimmer.
Dies ist nur so lange möglich, als zusammenhängende - breite - Abfallsäume anfallen. Fallen bei schmalen Abfallstreifen auf Grund der Säbelform des Bandmaterials unterbrochene Saumstreifen an, so erfordert die Saumwickelvorrichtung eine zusätzliche Arbeitskraft, welche die Saumanfänge zur Wickeltrommel führen muß.This is only possible as long as there are contiguous - wide - waste edges attack. Fall with narrow waste strips due to the saber shape of the tape material interrupted hem strips, the hem winding device requires an additional one Worker who must lead the beginning of the seam to the winding drum.
Ferner wird die Produktion unnötig dadurch aufgehalten, daß die Saumballen von Zeit zu Zeit von der Wickeltrommel entfernt werden müssen.Furthermore, production is unnecessarily delayed by the fact that the hem bales have to be removed from the winding drum from time to time.
Ferner wurde schon vorgesehen, den Saum von seiner Entstehungsstelle an dien Kreismessern durch feststehende Rohre zu einer Zerhack- bzw Zerkleinerungsvorrichtung für die Abfallsäume abzuleiten.Furthermore, it has already been planned to remove the seam from its point of origin on the circular knives fixed pipes to a chopping or to derive a shredding device for the waste seams.
Die feststehenden Rohre arbeiten nur so Tange störungsfrei, als der anfallende Saum breit und steif ist und, ohne zusammenzuknicken, bis zur Zerkleinerungseinrichtung einwandfrei durchstoßen kann.The fixed pipes only work as smoothly as the The resulting hem is wide and stiff and without buckling up to the shredding device can pierce perfectly.
Bei im Verhältnis zur Bandstärke jedoch schmalen Abfallsäumen bilden sieh Saumspiralen, welche die bisher bekannten Saumführungen leicht verstopfen. Besonders schwierig gestalten sich die Verhältnisse, wenn die Saumspiralen noch zusätzlich durch .die Säbelform des bearbeiteten Bandes unterbrochen sind.However, if the waste seams are narrow in relation to the tape thickness see hem spirals, which easily clog the previously known hem guides. The conditions are particularly difficult when the hem spirals are still are also interrupted by .the saber shape of the machined band.
Die Erfindung besteht darin, daß die Abfallsäume nach Passieren der in den Betrieben üblichen Saumaufnahme, die den. Saum an der Schnittstelle abnehmen, durch um die Längsachse rotierende Rohre zum Zerhacker geführt werden. Hierbei haben die Führungsrohre für die rechts und links anfallenden Säume einen jeweils entgegengesetzten Drehsinn, da :der rechts aus dem Srhneidspalt heraustretende Saum bei obenlieg!enden Innenmessern eine linksdrehende Spirale, der links heraustretende Saum bei obenlvegenden Innenmessern eine rechtsdrehende Spirale bildet (Blickrichtung gegen die Laufrichtung des Bandes).The invention consists in that the waste seams after passing the in the factories usual hem recording, which the. Remove the hem at the cut, be guided to the chopper by pipes rotating around the longitudinal axis. Have here the guide tubes for the hems on the right and left are opposite in each case Sense of rotation, there: the hem protruding from the right side of the gap at the top ends Inside knives have a left-turning spiral, the edge protruding to the left at the top Inside knives form a right-hand spiral (looking against the running direction of the tape).
Ertsprechend der Drehbewegung der Saum-. spirale wird der Drehsinn der Führungsrohre angesetzt; die Umfangsgeschwindigkeit der Rohrinnenwandung liegt dabei höher als die Schnittgeschwindigkeit der Kreismessersehere.According to the rotary movement of the hem. spiral becomes the sense of rotation attached to the guide tubes; the circumferential speed of the pipe inner wall is higher than the cutting speed of the circular knife scissors.
Hierbei ergibt sich der bereits in der Praxis erprobte Vorteil, daß die Saumspiralen auf Grund der Drehbewegung der Saumführungsrohre in Richtung der Zerhack- bzw. Zerkleinerungsvorrichtung gezogen und sicher abgeführt werden.This results in the already proven advantage that the hem spirals due to the rotational movement of the hem guide tubes in the direction of the Chopping or shredding device can be pulled and safely removed.
