Description

Device for diverting a strand immediately following a rolling stock Rolled stock strand The invention relates to a device for diverting a a strand of rolling stock in a feed level immediately following the strand of rolling stock, especially for high running speeds, with that on a previous one Rolling stock located on support by means of a guide tongue which can be pivoted in a vertical plane is diverted in a different conveying direction.

To divert the crop ends are behind rotating scissors vertical swiveling deflector flaps that can be controlled depending on the scissors are known (DP 2o3 324; DAS 1 007 145). The crop end is without between the scissors and the deflector flap Edition and sinks due to its own weight compared to the previous one Strand end. This supports the function of the reject flap. At high throughput speeds and for the derivation of greater lengths that cannot be lowered beforehand they still rest with the rear end on the guide when their tip is the When the deflector flap is reached, such deflector flaps are no longer operationally safe. That also applies to the removal of test pieces that are cut twice by the rotating scissors can be cut out of the strand and the length of a Have knife drum circumference.

Furthermore, a device for diverting crop ends is known (USA Patent 2 12o 313), in which between rotating scissors and a downstream guide tongue no support elements are provided for the rolling stock are. This is intended to ensure that the crop ends after being separated from the strand of rolling stock Tip over due to lack of support and thus removed from the roller table level will. To support this process, the roller table level should also be used Serve liftable guide tongue. When the rolling stock is moving at low speed, it is pivoting the guide tongue, on the one hand to divert the crop end and on the other hand to support the rolling stock railway, maybe still in of the available Time feasible. Meanwhile, at a rolling stock speed of 20 m / s, the to Pivoting the guide tongue available split second between the The leading end of the rolling stock and the immediately following tip of the rolling stock are conveyed away no longer has to swivel the guide tongue. Thus, one such device is not suitable for high rolling stock speeds.

The invention is based on the object of creating a device with which a rolling stock immediately following a rolling stock at high Throughput speed can be safely directed in a different conveying direction. This is achieved according to the invention in that the guide tongue has a Feed level can be raised and is arranged under this lowerable support, the Movement can be controlled opposite to the movement of the guide tongue. By early Raising or lowering the support can be done on the tip of the rod before it is reached the guide tongue a diverting effect can be exerted.

When the guide tongue is a rotating as a function of the knife movement Scissors is controlled, so it is advantageous to also depend on the support height controlled by the knife movement.

A guide section which can be pivoted in the vertical plane is used as a support intended.

In a further embodiment of the invention is on a knife shaft Pinion arranged which is in engagement with a gear with an eccentric is attached to the same catfish, against the tread with a roller the angle lever provided is held in contact with a push or pull element, whose arms each have a push rod on the vertically pivotable guide section or are hinged to an angled arm of the guide tongue.

In this way, the switch inevitably moves with the Knife movement. The conveying direction changes with each cut. A Another advantage is seen in the fact that the piston rod is on one arm of the angle lever a pressure cylinder which can be acted upon on both sides is aasgelenken. So can he Angle lever with its roller either pressed onto the running surface of the eccentric or deducted from it if the diversion is not desired after a cut will. However, since the diversion device only moves into the In this case, care must be taken to ensure that the Samples are only derived from this initial situation.

This is achieved according to a further feature in that an on the eccentric interrupter arranged the actuation of the system of the angle lever periodically blocks the valve of the compressed air cylinder that controls the eccentric.

In the drawing, an embodiment of the invention is in principle presented in several phases in the division of a sample. It shows Fig. 1 the Starting position of scissors and switch Fig. 2, the position immediately after first step with lowered guide section and raised guide tongue Fig. 3 the position during the second cut. FIG. 4 scissors and switch shortly before the starting position.

A rotating pair of scissors is in the pictures by two on knife shafts 1, 2 arranged knife drums 3, 4 shown, on which the knives 5, 6 received are. On the lower cutter shaft 2 'a pinion 7 is anchored, which at a Gear 8 is in engagement, which is anchored with an eccentric 9 on the same shaft 1o is. On the track 11 of the eccentric 9, a roller '12 is arranged adjacent, which is mounted in the vertical arm of an angle lever 13, which has a Push rod 14 with the angled arm 15 mounted on a bolt 16 Guide tongue 17 is connected by joints. By another push rod 18 is an articulated connection between the horizontal Arm of the bell crank 13 and the pivotable guide section 19 made.

The piston rod 2o of a pneumatic cylinder that is pivotably attached to the frame 21 is articulated on the vertical arm of the angle lever 13 and causes a corresponding Acting either the system of the roller 12 on the eccentric 9 or the lifting the same. In the starting position (Fig.1) in which the angle lever 13 by the eccentric 9 is pivoted the furthest to the right, the guide tongue 17 takes its deepest and the guide section 19 its highest position. Only in this position an interrupter 22 closes the circuit for the valve-controlled application of the compressed air cylinder 21 on the articulation side, so that the discharge of a sample can only be done from this position.

When the scissors start to cut, the eccentric 9 the upward movement of the guide tongue 17 and the downward movement via the angle lever 13 of the guide section 19 initiated, so that after the cut (Fig.2) the End of the strand 23 on the raised guide tongue 17, in the original direction runs, but the tip of the sample 24 looks on the lowered guide portion 19 is located. Before the separation point reaches the guide tongue 17, the separated Ends already away from each other, so 'that the diversion of the sample 24 under the Guide tongue 17 takes place in the new direction with certainty.

The scissors now run through until they come to the cut again ° (Fig.3), wherein the guide tongue 17 is pivoted downwards again and the guide section 19 is pivoted upwards so that the new strand tip 25 meets the raised guide section 19, while the end of the sample 24 still runs out under the lowered guide tongue 17 can (Fig.4).
