Description

Bindekopf 9 befestigt. Aus dem Kanal 10 der Führung 11, der beim Umführen des Bindedrahtes 12 durch die an der beweglichen oberen Umführung 13 angebrachte Platt j 14 verschlossen wird, wird dor Bindedraht 12 vor dem Reversieren des Treibers 15 durch Klauen 16 herausgezogen. Er wird dann beim Reversieren sowohl über das Bindegut 17 als auch über die Rolle 4 straffgezogen. Dabei verhindert ein die Rolle 4 teilweise umgreifender Abweiser 18 ein Vorbeigleiten des Bindedrahtes 12 an der Rolle 4. Bei genügend großer Zugkraft, die durch die einstellbare Vorspannung der Druckfeder 7 reguliert werden kann, schwenkt der Hebel 1, und somit erreicht auch die Rolle 4 eine Schräglage, so daß der Bindedraht 12 seitlich von der Rolle 4 abrutscht und durch den Treiber 15 vollständig um das Bindegut 17 gezogen wird. Nach Abrutschen des Bindedrahtes 12 schnellt der Hebel 1 durch die vorgespannte Druckfeder 7 in seine Ausgangslage gegen den Anschlag 19 zurück.Tying head 9 attached. From the channel 10 of the guide 11, which is closed during the bypassing of the binding wire 12 by the mounted on the movable upper detour 13 Platt j 14, the binding wire 12 is pulled out before the reversal of the driver 15 by claws 16. He is then tightened when reversing both on the binding material 17 and on the roller 4. In this case, the roller 4 partially encompassing deflector 18 prevents sliding of the binding wire 12 on the roller 4. With sufficiently large tensile force, which can be regulated by the adjustable bias of the compression spring 7, the lever pivots 1, and thus also reaches the roller 4 a Oblique position, so that the binding wire 12 laterally slips off the roller 4 and is pulled completely by the driver 15 to the binding material 17. After slipping the binding wire 12 of the lever 1 jumps through the prestressed compression spring 7 in its initial position against the stop 19 back.

Field of application of the invention

The invention hoists a binding wire tensioning device used to tighten the binding wire on wire binding machines used to bind sharp-edged bundles of fillet. Such Drahtbindornaschinon come in rolling mills for Arwendung.

Characteristic of the known state of the art

When strapping sharp-edged packages made of shaped steel with binding wire by means of the customary wire binding machines, it is impossible, in particular in wires with large cross-sections, to achieve a sufficiently firm and therefore firm bond by pulling the wire one-sidedly. Even with bilateral tightening the wire ends the required tightness can not be guaranteed.

To avoid this deficiency, solutions have been created in which the diversion consists of several separately operable segments, each releasing the wire one after the other (DE-AS 1268045, prospectus of the company "Titan" 1972 for the automatic strapping machine UVB) It is known to arrange additional roles within the bypass, over which the wire is stretched and release the wire after a partial wrap of the package was created by hydraulically triggered pivoting to complete the binding (DE-AS 2 209120, corporate title of the Fa "Schmitz & Soehne" 1980). Through the use of hydraulic actuators and controls such binding machines are very expensive, and the required panning times increase the time required within the technological flow.

Object of the invention

It is the object of the invention to reduce the equipment costs for binding machines and to reduce the time required for binding sharp-edged packages made of Fcrmstahl. A tight, tight-fitting binding should ensure a safe handling of the bound packages.

Explanation of the essence of the invention

It is the object of the invention to provide a tensioning device for binding wire to Drahtbindrrnaschinen that guarantees a tight-fitting and thus tight binding even when binding sharp-edged packages of mild steel on all sides of the Stapois.

According to the invention the object is achieved in that a roller is rotatably mounted so within the bypass of Drohtbindemaschino that the wire after leaving the guide initially rests on this role. In this case, the roller is mounted on a lever which is held by means of a prestressed spring and a spring plate with a defined force until the tensile force acting through the reversing operation on the current over the roller binding wire, is so large that it is for Schwenkon dos lever and thus leads to slipping of the binding wire of the roller blind. By a role in the binding wire running area partially embracing deflector, which is rigidly mounted on the bypass, premature slipping of the wire is prevented by the role.
