Abstract

The machine has a winding station (1) and an unwinding station (2), which are moved towards each other to transfer a coil (10), and the winding roller (3) on the intake side is lifted. The intake-sided unwinding roller (5) is lifted or lowered during or before the transfer, and the discharge-sided winding roller (4) is lifted to complete the process. The winding station is horizontally fixed, and the unwinding station is horizontally movable.

Description

The present invention relates to a bundle transfer system with a winding station with one take-up and one take-up reel and one unwind station with an unwinding roll on the inlet and outlet side, with the winding stations are movable towards each other, the winding station horizontally rigid and the Unwinding station is horizontally movable, the winding rollers in a frame with an inlet and an outlet end are stored.

Slabs are either close to final dimensions in thin slab casting machines continuously cast or rolled in a roughing street before continuous casting they are processed in a finishing train. The belt leaves the Vorstraße doing so at about three times the speed at which it later turns into the finishing train should come in. To keep the slab at its temperature, it is therefore in the State of the art - see e.g. Stahl und Eisen 103 (1983) No. 7, pages 31 to 26 - wound up into a bundle in a winding station of a bundle transfer system, the waistband being carried when winding up reels. After that a mandrel is inserted into the bundle eye and the bundle from the winding station transferred to the unwind station.

Already when inserting the mandrel into the eye and when relocating the collar unwinding of the tape is started. The winding up of the next one Ties to a bundle can begin, as can the already wrapped bundle Has reached the unwinding station.

Due to the insertion of the thorn into the eye of the federal government, the inner cool Turns more than the outer turns, which has a negative impact on the Rolling process in the finishing train and the quality of the rolled finished strip Consequence.

There are already operating procedures for bundle transfer systems and corresponding ones Confederation conversion plants known in which the transfer of the Confederation happens thornless. However, all of these processes and systems are complex and expensive. The systems for maintenance and repair work are also difficult accessible.

From the publication New developments expand coilbox applications, Iron and Steel Engineer, December 1996, pages 13 - 19 is an operating procedure for a Bundling system with a take-up station with one inlet and one outlet side Take-up reel and an unwind station with one entry and one exit side Unwinding roll known, with a tape in the winding station to one Bund is wound up. The waistband is carried by the winding rollers. To the The bundle is unwound from the take-up station to the take-up station transferred. In the unwinding station, the coil is carried by the unwinding rollers. For transferring, the take-up reel on the outlet side is lowered, causing the Bund shifted its position to the right and also on the lowered inlet side Unwind roll is applied. By lifting the take-up reel on the outlet side there is a further shift of the federal government towards the unwinding station, whereby the collar detaches from the take-up reel and on the take-out side Unwinding roll creates. Then we do the unwinding roll on the inlet side raised and thereby shifted the bundle to the unwinding station where the bundle rests on both rolls of the unwind station.

The object of the present invention is therefore a Bumdumsetzanlage to make available, by means of which, with little effort, cost-effective Safe tilting, lifting and lowering of the reel rollers is possible.

The object is achieved in that an upper frame, in which the winding rollers are mounted, with respect to the winding station is tiltable about an axis at the outlet end of the upper frame and a lower frame, which is movable with the upper frame on the outlet side End is connected to an axis on the barrel end of the lower frame is tiltable.

The winding station can be lifted or adjusted by coordinated adjustment be lowered.

Further advantages and details emerge from the following description of an exemplary embodiment. Show:

the winding station.

1, a bundle transfer system has a winding station 1 and an unwinding station 2 on. The winding station 1 comprises a winding roller on the inlet side 3 and an outlet-side winding roller 4. The unwinding station 2 has one inlet-side unwinding roller 5 and an outlet-side unwinding roller 6. The Bundling system according to the embodiment works as follows:

A support 7 is - e.g. coming from a roughing stand - via guide and bending rollers 8 of the winding station 1. There it becomes thornless, i.e. with open eye 9, wound into a bundle 10. While winding up the collar 10 is carried and rotated by the driven take-up rolls 3, 4.

When the pre-strip 7 is completely wound up, the coil opener 11 is on the Bundle 10 put on and - still in the winding station 1 - started unwinding the federal government 10. During the beginning of the unwinding process, the bundle 10 then becomes the unwinding station 2 transferred. After the transfer, the bundle 10 is removed from the unwinding rolls 5, 6 worn. The actual transfer process will now described below in connection with Figure 2.

Fig. 2a shows the positions of the winding rolls 3 to 6 before the start of Transfer process. At this time, the federal government 10 is still from the Winding rolls 3, 4 worn.

At the beginning of the transfer process - as can be seen from FIG. 2b - the take-up reel 3 raised and the winding stations 1, 2 moved towards each other. If necessary, the inlet side Unwinding roll 5 can be raised slightly. This forms between the take-up reel 4 and the take-up reel 5 a trough in which the collar 10 can rest briefly.

Then - according to Fig. 2c - to complete the transfer of the federal government 10, the winding roll 4 on the outlet side, so that the collar 10 is securely mounted on the unwinding rollers 5, 6.

Finally - see Fig. 2d - the winding stations again moved away from each other, which then ends the transfer process. From this point on, the collar 10 is removed from the unwinding rollers 5, 6 worn alone.

During the entire unwinding and transfer process rotate the winding rollers 3 to 6 and thus also the collar 10. Even after the When the transfer is complete, the unwinding rollers 5, 6 rotate the bundle 10. However, since this is now being carried out without a thorn, the last one must Be held down by suitable means to a to ensure proper entry of the preliminary strip 7 into the finishing train. This can be achieved, for example, by means of the collar opener 11 become. Alternatively, a retention roller or a retention pin can also be used be used.

From the above description it can be seen that the winding stations 1, 2 can be moved towards each other and both winding rollers 3, 4 and optionally also the unwinding roll 5 on the inlet side can be raised. In order not to have too many degrees of freedom in a winding station 1, 2 The winding station is preferably to be realized 1 rigid in the horizontal direction and the unwind station 2 can be moved horizontally towards or away from the winding station 1. This is indicated in FIG. 1 by the double arrow A. The horizontal movement of the unwinding station 2 can be hydraulic, for example or done by an electric motor.

The liftability of the two winding rollers 3, 4 is constructive easiest to implement according to FIG. 3. According to this figure the take-up rolls 3, 4 are mounted in frame 12, which has an inlet side End 13 and an outlet end 14 have. One of the frames 12 is e.g. B. by means of a hydraulic cylinder 15, which is arranged in the vicinity of the inlet end 13 by a Axis 16 pivotable, which at the outlet end 14 of the frame 12 is arranged. The other of the frame 12 may e.g. B. by a another hydraulic cylinder 17 pivoted about a further axis 18 become. So both rewinding rolls can be constructed in a structurally simple manner 3.4 can be raised and lowered, while maintaining the distance the take-up rolls 3, 4 are kept constant from one another with certainty becomes.

Finally, it should be mentioned that the winding station 1 by coordinated adjustment of the hydraulic cylinders 15, 17 of course can also be raised or lowered. if desired or required, the unwinding station can of course also 2 - e.g. B. by means of hydraulic cylinders - can be raised and lowered be trained.
