EP1984129A1 - Apparatus for winding and unwinding rolled strip - Google Patents

Abstract

The invention relates to an apparatus for winding and unwinding rolled strip (WB) discharging from a mill train (WS), in which apparatus the rolled strip (WB) discharging from the mill train (WS) is introduced by a set of bending rolls (BR) into a winding chamber (WK) having a rotationally driven roller pair (RP) and is wound into a coil (WB), and the coil is then put onto a roller table (GR) and unwound from these rollers with the direction of rotation being reversed and the start of the strip is fed to a driver device (RT). The apparatus is improved by a supporting slide (TS) which can be pushed into the winding chamber (WK) and in whose side walls a pivoted lever (SH) is mounted, the free end of which carries a pressure roller (AR) which can be put onto the rolled strip coil and pushes the latter out of the winding chamber (WK) onto the adjoining roller table (GR).

Description

Device for winding and unwinding of rolled strips

The invention relates to a device for winding and unwinding of rolled strips, in which detects the emerging from the rolling train of a set of bending rolls, introduced into a rotary driven rollers having winding chamber, wound into a bundle and then applied the federal government on a roller table and below Direction of rotation of the roller table rolls unwound again and the beginning of the tape is fed to a drive device.

In a known device of this type WO 03/013753, the band pre-bent by the bending rollers is fed to a winding chamber having a plurality of driven rollers, and the supporting rollers, after the band has been wound into a bundle, are jointly introduced into the roller gangway and allow this position the further transport of the wound federal government from the winding position out to a downstream, driven rollers having carrying means. This support device is displaceable in the direction of tape movement and allows by reversing the direction of their roles, the unwinding of the overlying federal with subsequent introduction of the beginning of the tape in a downstream driver device. Another known proposal (EP PS 933 147) is to provide two pairs arranged behind each other of support rollers for the wound collar, which are mounted in each other and movable away from each other tilting frame and allow each wound coil from the Insert winding position in an unwinding position.

In these devices, difficulties arise in the transport of the Federal of the supporting idlers of the winding chamber on the roles of downstream transport device. Because this transport emanates from the stoppage of the Federal in the winding chamber and because the federal government in addition to the transport movement additionally begins with the unwinding rotation.

The invention therefore proposes to push the federal government out of the winding chamber out onto a roller conveyor section arranged downstream of the winding chamber, the transport plane of which being angularly adjustable to the support plane of the winding chamber. This displacement of the collar is effected according to the invention by a pivoting lever which is arranged in the side walls of a support slide which can be inserted into the winding chamber and carries a pressure roller at its free end. This pressure roller rests on the circumference of the collar and pushes it when pivoting the pivot lever out of the winding chamber out on the downstream roller table section. Subsequently, after introducing the next federal in the winding chamber, the pivot lever is pivoted back to its original position and placed the pressure roller on this collar.

The invention will be explained in more detail with reference to the embodiment shown in the drawing. In the drawing show:

Figure 1 shows the device seen from the side in a schematic representation and Figure 2 shows the device of Figure 1 in another position.

The rolled strip is introduced from the rolling train via a bending roller assembly BR introduced into the winding chamber WK and there wound on a pair of rollers RP with slightly inclined roller level lying to a bunch B. This roller pair RP is followed by a group roller table whose roller plane R of the rollers of the winding chamber WK runs slightly counter-inclined and is adjustable in inclination with the aid of a servomotor SM. Subordinate to this group roller table GR is a straightening unit RT. In the winding chamber WK a support carriage TS is retractable, in the side walls, above the rolled strip collar WB a pivot lever SH is articulated, which carries at its free end a pinch roller AR, which is placed on the circumference of the federal. As seen from Fig. 1 in conjunction with Fig. 2, the wound in the winding chamber WK collar B is pushed with the help of this pivot lever SH by the pinch roller AR from the winding chamber WK out on the group roller table GR and resting on this with the help of the Richttreiber RT arranged swivel castor LR supplied to this.

Claims

claim 1. An apparatus for winding and unwinding from a rolling mill WS emerging rolling belts WB, in which the rolling train WB emerging from the rolling mill WS introduced by a set of bending rolls BR in a rotationally driven roller pairs RP having winding chamber WK, wound into a collar WB and the Bund then applied to a roller table GR and unwound reversing direction of these roles and the beginning of the tape is fed to a driving device RT, characterized by an insertable into the winding chamber WK support carriage TS, in whose side walls a pivot lever SH stores whose free end auflegbare one on the rolled strip , this carries from the winding chamber WK out on the subsequent roller table GR sliding pinch roller AR.
