The invention relates to a rotary tube reel with a downstream, continuously running one Conveyor device for conveying away successive lengths of wire rod in pulled apart, overlapping turns.

In the case of wire mills, the per rolling wire with a rotary tube reel and a subsequent conveyor belt equipped, the gap between the lying turns of the preceding and the subsequent wire length on the conveyor belt by the bar gap time and the speed of the determined by the conveyor belt. If one wants for reasons of economic exploitation of the In addition to a high rolling speed, the wire mill should also strive for the closest possible bar sequence, this inevitably results in difficulties when separating the individual wire lengths in the ring collecting station at the end of the conveyor belt.

It is known that the rings in the collecting basket can be pushed in or folded in or swiveled in ken of an intermediate floor or other interception means to separate from each other, but have these Devices have the disadvantage that short gaps in the bar cannot be properly detected. aside from that there is still the danger that the overlapping as of the turns of the following over the previous wire length the new turns of the underlying old windings are captured and carried away.

It still stands to reason that the gap between the end of the previous one and the beginning of the next one stands out To increase wire length by keeping the conveyor belt during the wire feed break accelerated and shortly before the laying of the first turn of the following wire length again the exit speed is decelerated. However, in the case of bar gaps of 1 to 2 see, as in High-performance wire mills are generally aimed for, even in this way no significant enlargement the winding gap on the conveyor belt. It also has a brief acceleration and delaying the conveyor belt has the disadvantage that this is due to the inertia forces occurring with is associated with a great technical effort.

The object of the present invention is now to fill the gap between the stored on a conveyor belt To enlarge turns of successive wire lengths in such a way that at the ring collecting station a perfect separation of the individual wire lengths is made possible.

It is known to separate the individual wire lengths by a rotary tube reel in two winding positions with a downstream one

to bring about movable reel head, whereby the reel head has two correspondingly arranged side by side, are assigned to the winding base opposite raisable and lowerable winding baskets. That Rolled material coming from the rolling mill is fed through the reel head into the respective upright winding basket inserted into a covenant. After processing a length of wire into a bundle, the reel head becomes the assigned to another winding basket, so that the first winding basket to remove the finished wire bundle is free. From this known device, however, no teaching can be found in what way an increase in the gap between the end of a first length of wire and the beginning of a subsequent wire length from on a continuously running conveyor device in pulled apart, overlapping turns deposited wire rod is to be achieved.

According to the invention, the aforementioned object is achieved in that the rotary tube reel over the inlet-side area of the conveyor approximately parallel to the conveying direction in a manner known per se Way is movable between two end positions, the movement of the rotary tube reel in the conveying direction can be controlled with small and opposite to the conveying direction with high speed.

According to a further feature of the invention, it is particularly advantageous if the winding layer moves one way forward and backward covered which is larger than the winding diameter, reduced by the covered in the gap time Conveying path. This means that the first turn of a subsequent length of wire is the last Winding of the previous wire length no longer overlaps, but behind this on the conveyor belt is deposited and therefore there is no longer any risk of the turns of the subsequent wire length the last turns of the previous wire suction 638/1157

length to be captured and carried away in the collecting station. In addition, you can now without difficulty hand cut the thickened start and end pieces of each length of wire on the conveyor belt will.

In a further embodiment of the invention, a feed pipe connected to the rotary pipe reel is shown in FIG Direction of movement of the rotary tube reel over a stationary guide tube according to the distance can be moved between the two end positions.

In the figures, an embodiment of the device according to the invention is shown. It shows Fig. 1 shows a movable rotary tube reel with a downstream conveyor belt and

2 shows a plan view of the stored windings two consecutive lengths of wire.

In Fig. 1 is the coming from a rolling mill wire through a rotary tube reel 1, which is with a Rotary tube 2 rotating about a horizontal axis and one arranged in its lower area Tripping edge 3 is equipped in non-concentric, overlapping turns on one Conveyor belt 4 deposited and from this after passing through a cooling or heat treatment section a ring collecting station, where it is combined in as wire rings. The rotary drum reel 1 is attached to a carriage 5 guided in rails 6 and above the area on the inlet side of the conveyor belt 4 arranged to be movable approximately parallel to the conveying direction. With the rotary tube reel 1, a feed pipe 7 is attached to the inlet side, which via a stationary guide pipe 8 accordingly the travel of the rotary tube reel 1 is displaceable.

The rotary tube reel 1 is quickly put into its position with a power tool during the gap time back end position moved back and slowly pushed into its front end position while the rod is running, the speed of the conveyor belt 4 corresponding to the feed speed of the rotary tube reel 1 is expediently raised for the duration of the advance so that the same Winding distances arise.

FIG. 2 shows the top view of the turns of two successive turns deposited on the conveyor belt 4 Wire lengths, the travel of the rotary tube reel 1 being selected to be so large that the distance from the last turn of the previous wire length to the first turn of the following Wire length is greater than the coil diameter.
