Method and apparatus for stacking rolled strip strip parts

Field of application of the invention

The invention can be applied when stacking strip parts of rolled strips.

Characteristic of the known technical solutions

In strip processing plants there is often the demand to remove larger strip parts, especially at the beginning and end of a strip, in a simple and fast way from the strip run. Frequently, for example, in the case of stainless steel and non-ferrous metals, e.g. were rolled in a Reversierduo, separated the non-väl / alte end, welded to a roll to be rolled and so used repeatedly. The reused ends have a length of 4 to 10m,

In order to avoid loss of time, frequent seizure of longer pieces of tape to be disposed of is required to remove the long pieces of tape uncut, e.g. in the length of 4-10 m next to the belt treatment plant to stack. In known systems a long roller table is arranged for this purpose in the tape processing plant behind the scissors, are pushed onto the tape parts and taken after cutting by a special crane and after a transverse transport from the tape out laterally next to the tape processing Plant deposited to form a stack v / earth.

The disadvantage here is that the roller table must be designed within the band treatment plant on the max, tape length, so that the space requirement of the system is considerable, "It can also losses at the end of the tape arise because the tape to a greater length no longer under tension »Other disadvantages in working hours result z, B _e , if only shorter band parts are removed.turns or bands are processed, from which no parts are removed. In all these cases, the time for the introduction of the tape in the system is increased.

Object of the invention

The aim of the invention is to provide a method and a device, whereby a more economical stacking of strip parts of rolled strips is possible «

Presentation of the essence of the invention

The present invention has for its object to provide a method and an apparatus for performing the method, which allow a great deal of space and time required stacking even long, cut tape parts in addition to the strip processing plant »

This object is achieved according to the method by curling the cut strip part in the tape to a ring, the ring transported in the transverse direction from the tape to the stacking point, and unrolled again in the stretched state and then the stretched tape portion stores on the stacking point Method has the great advantage that the band part rolled up into a ring has only a fractional

requires part of the distance within the belt processing plant and at the same time a space-saving stacking of the tape parts on the stacking point is possible, since the ring is unrolled immediately after transport from the tape processing system again.

A suitable device for carrying out the method v / eist equipped with a bending rollers for curling and bending rollers for unrolling machine, which can be moved in the transverse direction to ι tape running between a position in the tape behind the scissors and a position in front of the stacking point for the cut tape parts is. Rollers for belts that operate on the principle of a bending machine, wherein the tape is bent to curl by a three-roll bending set belong to the prior art (see "production of cold rolled strip", Verlag Stahl-Eisen Dusseldorf, 1970, page 167) · In order to allow the roll-out immediately adjacent to the belt treatment plant in front of the stacking point, in the subject of the application the bending machine is also provided with a bending set for unrolling, eg with three wheels, equipped. For this purpose, only an additional bending roller is required, since the other two bending rollers can be used for both rolling and for unrolling. According to a further preferred embodiment, the bending roller having the bending roller is rotatable about its own axis, so that the spatial arrangement of Stacking point with respect to the tape processing system is more freely selectable.

Particularly preferred is an embodiment in which the bending machine in front of the outside arranged Enttrollbiegerolle a tape-detecting measuring barrier, e.g. a photocell, which, to the drive of the bending machine "a

from. At the end of the truncated component, the stop signal triggered ο This photocell, on the one hand, prevents the rear end from rolling in when the long end is being rolled into the ring. is drawn in far. The rolling-in process is interrupted · before the rear long end has reached the outer bender roller. When unrolling, therefore, no separate threading is required. In addition, the measuring barrier serves to stop the bending machine after unrolling. Purely an automatic operation of the strip processing system. In addition, the stop signal can be used to start the transverse transport from the strip to the position before the stacking point immediately after the triggering of the stop sign.

A significant advantage of the teaching according to the application is the fact that the little space within the tape processing system engaging rolled-up tape part unrolls immediately after the cross transport from the tape processing unit out again in the stretched state and then stretched is placed on the stacking point. Thus, it is possible to stack in a space-saving arrangement a plurality of tape parts and transported at a later time collected a variety stacked tape parts. At the same time, there is the advantage that the ends are directed after unrolling and unchanged the "reuse can be supplied" space-saving arrangement results in only a small disability for the operator, which compared to the known transverse transport crane with the risk of accidents is lower preferred embodiment of the bending machine with Meßschrank'e also gives the advantage that the system works largely fully automatically *

embodiment

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

Pig. 1: a side view of the device according to the invention;

2 shows a plan view of the device according to the invention,

The expiring of a reel 1 metal strip 2 first passes through a roller leveler 3 and then passes a pair of scissors 4. The metal strip 2, the z. B. has a thickness of about 3 mm, has an approximately 8 m long end 5 considerably greater strength, e.g. 8 mm, on. This thicker long end 5 must be separated from the metal strip 2 and removed from the strip processing system. The long end 5 is separated from the metal strip 2 by means of the scissors 4 and rolled up by a bending machine 6 into a ring 7.

Like Pig. 2, the bending machine 6 is movable on rails 8 transversely to the strip run between the belt position 9 and the position 10 from a stacking point 11.

The bending machine 6 has four bending rollers 14 »15, 16 and 17. Following the last bending roller 17, a roller cage 18 is arranged, which receives the ring 7. By dipping the bending roller 16 between the bending rollers 15 and 17, the long end 5 is curled when curled 'to the ring 7, while rolling the bending roller 15 between the externally arranged bending roller 14 and the bending roller 16 is immersed, so that the bent to the ring 7 long End 5 is again transformed into the stretched state. In front of the outside

Bending roller 14 is a tape-detecting measuring barrier 19 »e.g. a light barrier, arranged, which gives a stop signal to the drive of the bending machine 6, if after passing the long end 5, the path between the two measuring organs of the measuring barrier 19 is free »

In the example shown, the stacking point 11 is arranged parallel to the roller leveler 3, so that the rolled ring 7 in the opposite direction to the strip from the bending machine 6 promoted and then placed on the stacking point 11 .. The bending machine 6 is according to a preferred embodiment. designed so that it can rotate about a vertical axis, so that the Stapels'telle 11 just as in the transverse direction to the tape or on the opposite side of the rails 8, i. mirror image of the arrangement shown, set v / ground can. The operation is as follows:

The welded at the front end of the tape 2 long end 5 is deformed by the bending rollers 15, 16 and 17 to the ring 7 and received by the bending machine 6 · The scissors 4 separates the long end 5 from the belt 2 «Once the severed end of the Measuring barrier 19 has happened j is the drive of the bending rollers 14s 15, 16, 17 stopped _? so that the rear end of the long end 5 comes to a standstill before the bending roller 14 "The stop signal also gives the command that the bending machine 6 can move from position 9 across the tape to position 10 * This is the way for the band 2 free, so that for the removal of the long end 5 is given only a short time interruption. In position 10 in front of the stacking point 11, in turn, the bending rollers 14 »15» 16 come into operation, so that the long end 5 in stretched position.

The corresponding process is repeated when the rear long end is cut off from the belt 2, or at the next following belt, until a large number of cut off long ends are deposited on the stacking point 11. This multiplicity of long ends 5 can then be transported away collectively. The unrolling of the ring 7 at the stacking point 11 can take place in parallel with the work which is necessary within the strip processing system for the metal strip 2. Thus the unrolling can take place while the metal strip 2 is the processing frame 12j eg a slitting shear, happens and reaches the take-up reel 13.
