Abstract

Pivoting control flaps are located in a novel arrangement, within the reducing section (6) at the outlet nozzles of air supply ducts, below a roller conveyor for the transport of wire loops. Pref. the control flaps may be hinged up adjustably in the cross section, and can completely close the outlet. Several of the nozzle-like reductions are connected to an air supply duct, each individual tapered section being allocated control flaps with independent adjustment and setting.

Description

Die Erfindung bezieht sich auf die Anordnung der schwenkbaren Blasluft-Regelklappen in, unter den Rollen eines Rollgangs für den Drahtschlingentransport angeordneten Luftzufuhrschächten, die eine, zwischen den Rollgangsrollen endende düsenartige Verjüngung aufweisen.The invention relates to the arrangement of the pivotable blown air control flaps in air supply shafts arranged under the rollers of a roller table for the wire loop transport, which have a nozzle-like taper ending between the roller table rollers.

Bei einer bekannten Anordnung dieser Art sind die Regelklappen in dem Luftzufuhrschacht, durchweg in mehr oder weniger geringem Abstand hinter dem, die Blasluft erzeugenden Lüfter angeordnet. Diese Anordnung bringt den Nachteil mit sich, daß die aus den düsenartigen Verjüngungen der Luftzufuhrschächte austretenden Blasluftströme nur durch die fixe Anordnung und die Abmessungen der Luftaustrittsöffnungen und deren ebenfalls fixen Querschnitt in Verbindung mit der, durch die Regelklappen im Luftzufuhrschacht beeinflußten Menge pro Zeiteinheit beeinflußt werden.In a known arrangement of this type, the control flaps are arranged in the air supply shaft, all at a more or less short distance behind the fan which generates the blown air. This arrangement has the disadvantage that the blowing air flows emerging from the nozzle-like tapering of the air supply ducts are only influenced by the fixed arrangement and the dimensions of the air outlet openings and their likewise fixed cross-section in connection with the quantity per unit of time influenced by the control flaps in the air supply duct.

Der Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu beseitigen und eine Möglichkeit zu schaffen, Menge und ggfs. auch Richtung der aus der düsenartigen Verjüngung der Luftzufuhrschächte austretenden Blasluftströme beim Austritt aus der Austrittsöffnung der Verjüngung zu beeinflussen.The object of the invention is to eliminate this disadvantage and to create a possibility of influencing the quantity and possibly also the direction of the blown air streams emerging from the nozzle-like tapering of the air supply ducts when they emerge from the outlet opening of the taper.

Diese Aufgabe wird dadurch gelöst, daß die Regelklappen im Bereich der Austrittsöffnung der düsenartigen Verjüngung des Luftzuführschachtes in deren Querschnitt einstellbar angelenkt sind.This object is achieved in that the control flaps are articulated in their cross-section in the region of the outlet opening of the nozzle-like tapering of the air supply shaft.

Mit dieser Anordnung können die aus der Austrittsöffnung austretenden Blasluftströme unmittelbar vor deren Auftreffen auf die, auf den Rollen des Rollgangs transportierten Drahtschlingen beeinflußt werden.With this arrangement, the blowing air streams emerging from the outlet opening can be influenced immediately before they strike the wire loops transported on the rollers of the roller table.

Wie die Erfindung weiter vorsieht können die Regelklappen auch in eine, den Austrittsquerschnitt ausfüllende Schließstellung einschwenkbar sein, so daß die Austrittsöffnungen z. B. bei längerem Stillstand der Einrichtung oder beim Transport von Drahtschlingen, die keiner Blasluftbeaufschlagung bedürfen, verschlossen und gegen den Eintritt von Fremdkörpern oder Flüssigkeiten geschützt sind.As the invention further provides, the control flaps can also be pivoted into a closed position filling the outlet cross section, so that the outlet openings, for. B. in the event of a long standstill of the facility or when transporting wire loops that do not require any blast air, are locked and protected against the entry of foreign bodies or liquids.

Eine weitere erfindungsgemäße Möglichkeit besteht darin, daß bei der an sich bekannten Zuordnung einer Mehrzahl von düsenartigen Verjüngungen zu einem gemeinsamen Luftzufuhrschacht die den einzelnen Verjüngungen zugeordneten Regelklappen unabhängig voneinander einstellbar auszubilden. Diese Ausbildung schafft die Möglichkeit, die Beaufschlagung der auf dem Rollgang transportierten Drahtschlingen durch die Blasluftströme örtlich zu variieren.A further possibility according to the invention consists in the fact that, in the known assignment of a plurality of nozzle-like taperings to a common air supply shaft, the control flaps assigned to the individual taperings are designed to be adjustable independently of one another. This training creates the possibility of locally varying the impact of the wire loops transported on the roller table by the blown air currents.

Die Erfindung wird anhand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnung zeigen

Wie aus Fig. 1 zu ersehen sind die Austrittsöffnungen 1 und 2 der düsenartigen Verjüngungen zwischen den Rollen 3 des Rollgangs auf einem Düsendeck 4 angeordnet. In den Austrittsöffnungen, die sich über die Breite des Rollgangs erstrecken sind Blasluft-Regelklappen 5 angeordnet und zwar, wie sich aus Fig. 2 ergibt sind diese Regelklappen 5 im Bereich der Austrittsöffnung der düsenartigen Verjüngung 6 bei 7 an einem der Ränder der Austrittsöffnung 1 angelenkt. Die Regelklappen 5 können zur Beeinflussung des aus der Austrittsöffnung 1 austretenden Blasluftstroms in unterschiedliche Winkelstellung eingebracht werden und lassen auch durch Einfahren in eine, hier waagerechte Stellung ein Verschließen der Austrittsöffnung 1 der düsenartigen Verjüngung 6 zu.As can be seen from Fig. 1, the outlet openings 1 and 2 of the nozzle-like tapering between the rollers 3 of the roller table are arranged on a nozzle deck 4. Blown air control flaps 5 are arranged in the outlet openings, which extend across the width of the roller table, specifically, as can be seen from FIG. 2, these control flaps 5 are articulated in the region of the outlet opening of the nozzle-like taper 6 at 7 on one of the edges of the outlet opening 1 . The regulating flaps 5 can be introduced into different angular positions in order to influence the blown air flow emerging from the outlet opening 1 and also allow the outlet opening 1 of the nozzle-like taper 6 to be closed by moving into a position which is horizontal here.
