Definitions

  • the present invention is based on a method for removing binding bands from a coil produced by winding a band, the coil having two end faces and a lateral surface as well as a coil eye with an eye axis and the binding bands having a binding band width.
  • the present invention is also based on a removal system for removing binding bands from a coil produced by winding a band, the coil having two end faces and a lateral surface as well as a coil eye with an eye axis.
  • a finish-rolled strip is usually reeled into a coil and transported in this form from a finishing train to another plant, in which the coil is reeled off again and the strip is then sent for further processing.
  • the distance over which the coil is transported can be a few 100 m or many km. Further processing can be, for example, cold rolling with or without previous pickling. Other systems are also possible.
  • the coil is tied with binding straps that run around the lateral surface of the coil.
  • the binding tapes must be removed before further processing in the further plant become. The removal of the binding bands is preferably carried out automatically.
  • the coil is positioned for this purpose on a pair of floor rollers, the floor rollers being tapered in those areas in which the binding straps of the coil run. This makes it possible to automatically separate the binding tapes and then automatically pull them off the coil.
  • the tie straps are not in their expected positions, the tie straps can be separated in the entrance area of the further system, but cannot be pulled off the coil, since the tie straps are clamped between the coil and the floor rollers. In this case, the binding tapes have to be removed manually. This is time consuming and cumbersome.
  • the document DE3331577A shows a device for separating and removing a binding tape.
  • the object of the present invention consists in creating possibilities by means of which an automated removal of binding bands is possible independently of their positioning on the coil.
  • the removal of the binding straps is often involved in the transport of the coil from an input area of a further plant to a processing area of the further plant.
  • the coil is transported from the input area of the further system to the processing area of the further system in that the coil is transported by means of a step beam in several stages in a substantially horizontal conveying direction from a first fixed saddle area to a second fixed saddle area, from the second fixed saddle area to a third fixed saddle area, etc. is conveyed to a last fixed saddle area, so that the coil rests alternately on one of the saddle areas and the step beam.
  • a predetermined one of the saddle areas corresponds to the first support
  • the step bar to the corresponds to the second support
  • step a) is carried out while the coil rests on the predetermined saddle area
  • step b) is carried out while the coil is being conveyed by means of the step beam from the predetermined saddle area to the subsequent saddle area.
  • the step bar corresponds to the first support
  • a predetermined one of the saddle areas corresponds to the second support
  • step a) is carried out while the coil is being conveyed by means of the step bar from the previous saddle area to the predetermined saddle area
  • the step b) is carried out while the coil rests on the predetermined saddle area.
  • the first partial area contains the edge areas of the lateral surface of the coil adjoining the two end faces and the second partial area contains a central area of the coil spaced apart from both end faces.
  • the coil is supported “outside” in step a) so that the binding straps arranged “inside” can be removed automatically, and then supported “inside” in step b) so that the binding straps arranged “outside” are automatically removed can become.
  • the reverse procedure is also possible, that is to say the first partial area contains the central area of the coil and the second partial area contains the two edge areas of the coil.
  • Other procedures are also possible, for example that in steps a) and b) the coil is supported once on the left, in the middle and on the right and once half on the left and half on the right.
  • the eye axis can be oriented essentially orthogonally to the conveying direction. This is in contrast to the prior art, in which the eye axis is mostly oriented in the conveying direction.
  • This procedure has the particular advantage that at the transition to the processing area of the further system, the coil does not rotate by 90° around a vertical running axis must be rotated, but can be further processed directly.
  • configurations are also possible in which the eye axis is oriented essentially in the conveying direction.
  • the coil is preferably rotated about its eye axis, so that a tape head of the tape has a predetermined orientation with respect to a vertical plane containing the eye axis. This can prevent the coil from "jumping open” after loosening and removing the binding straps, i.e. the outermost turn detaching from the coil.
  • a diameter of the coil is determined by measurement. This can be useful in particular in order to adapt subsequent machining processes depending on the diameter.
  • the diameter is preferably determined while the coil is resting with the first partial area on the first support in step a) and/or with the second partial area on the first or second support in step b).
  • the removal of the binding straps is integrated into the transport of the coil from an input area to a processing area of another system, it is possible for a predetermined one of the saddle areas to correspond to the first support and the step bar to correspond to the second support.
  • the crotch bar corresponds to the first support and the predetermined saddle area corresponds to the second support. In both cases it can be sufficient if the removal device can only be operated in the area of the predetermined saddle area.
  • the removal device by means of which the binding tapes are removed, can in particular be designed as a robot.
  • the removal device preferably has an optical detection device for detecting the binding bands surrounding the coil. As a result, the binding bands can be detected in a particularly simple and reliable manner.
  • a metal strip 1 is rolled in a rolling mill. Only the last roll stand 2 of the rolling mill is shown. After rolling, the metal strip 1 is coiled into a coil 4 by means of a coiler 3 . The reeled coils 4 are then tied with binding tapes 5 (see FIG 2 ) and removed from the rolling mill.
  • the FIG 2 and 3 show a coil 4 after binding.
  • the coil 4 essentially has a cylindrical shape. According to the FIG 2 and 3 the coil 4 thus has two end faces 6 and a lateral surface 7 .
  • the coil 4 also has a coil eye 8 with an eye axis 9 . As far as the procedure according to the invention is concerned, the eye axis 9 is generally oriented horizontally.
  • the coil 4 has a diameter D and a coil width B.
  • the binding straps 5 extend around the coil 4 on the lateral surface 6 . They have a binding bandwidth b.
  • the binding band width b is considerably smaller than the coil width B.
  • the binding band width b can be 4 cm, while the coil width B can be 1 m, for example.
  • the number of binding tapes 5 can be as required. It is usually between one and four. According to the illustration in FIG 2 For example, three binding straps 5 can be present.
  • the coil 4 is initially in accordance with FIG 4 with a first partial area of its lateral surface 7 on a first support 10 .
  • the first partial area extends—of course—only over part of the circumference of the coil 4.
  • the first partial area extends as shown in FIG FIG 4 seen in the direction of the eye axis 9 only over part of the coil width B.
  • the first support 10 can have two supports 11, which in turn have a respective support width b' seen in the direction of the eye axis 9 and seen from each other by a predetermined one in the direction of the eye axis 9 support spacing a are spaced apart.
  • the two supports 11 can have a support width b' of 10 cm and be spaced apart by 50 cm.
  • the numerical values mentioned are of course to be understood purely as examples.
  • the coil 4 rests on the supports 11 in such a way that the in FIG 4 left end 6 has a distance of 5 cm from the left support 11 and consequently with a coil width B of 1 m the right end 6 has a distance of 35 cm from the right support 11 and furthermore - purely by way of example - the binding tape width b is 4 cm, so can be removed in this state, all binding tapes 5, the center of which has a distance from the left end face 6, which is either between 17 cm and 53 cm or greater than 67 cm. A certain tolerance can still be taken into account as a precaution, so that, for example, only binding straps 5 are removed whose center is at a distance from the left end face 6 which is either between 19 cm and 51 cm or is greater than 69 cm.
  • FIG 2 there are a total of three tie straps 5, with the center of the two outer tie straps 5 each being spaced 15 cm from the adjacent end face and the center of the middle tie strap 5 being spaced the same distance from both end faces 6, so in this state the left tie strap 5 clamped by the left support 11 and therefore cannot be removed in this state.
  • the middle and the right binding tape 5 can be removed. 5 shows this state in which the two binding tapes 5 mentioned have been removed.
  • the coil 4 lies with a second partial area on the first support 10 .
  • 6 shows this condition.
  • the second sub-area extends only over part of the circumference of the coil 4, as seen in the circumferential direction around the eye axis 9.
  • the second sub-area extends as shown in FIG 6 seen in the direction of the eye axis 9 likewise only over a part of the coil width B. It is crucial that the first and the second partial area are spaced apart from one another by at least the binding tape width b, viewed in the direction of the eye axis 9 .
  • the coil 4 can rest on the supports 11 in such a way that the FIG 4 right end face 6 has a distance of 5 cm from the right support 11 and consequently with a coil width B of 1 m the left end face 6 has a distance of 35 cm from the left support 11.
  • those binding tapes 5 which have not been removed before can now be removed by means of the removal device 12 .
  • binding straps 5 can now be removed whose center is at a distance from the left end face 6 which is either less than 33 cm or between 47 cm and 83 cm.
  • a certain tolerance can again be taken into account, so that, for example, only binding straps 5 are removed whose center is at a distance from the left end face 6 that is either less than 31 cm or between 49 cm and 81 cm.
  • FIG 7 shows this state in which the remaining binding tapes 5 are also removed.
  • the removal of the binding bands 5 as such can be done in the same way as in the prior art.
  • the associated removal device 12 - ie the device which removes the binding tapes 5 from the coils 4 - can thus be designed as required be.

  • the positions of the binding bands 5 on the coil 4 can be specified by an operator to a control device 13 for the removal device 12 (usually a numerical control) or for them to be otherwise known.
  • the removal device 12 has an optical detection device 14, by means of which the binding bands 5 surrounding the coil 4 are automatically detected.
  • the optical detection device 14 can be designed as a laser scanner, for example. If the optical detection device 14 is present, the optical detection device 14 transmits the data it has captured (e.g. images) or the evaluation results based thereon to the control device 13. The control device 13 then takes into account the data or evaluation results transmitted to it when controlling the removal device 12.
  • a measuring device 12 ′ is preferably also assigned to the distance device 12 .
  • the coil diameter D in particular can be determined by means of the measuring device 12' and output to a control device (not shown in the figures).
  • the coil 4 can rest alternatively with the first partial area or with the second partial area on the first support 10 .
  • the supports 11 form a sequence of supports 11.
  • the supports 11 have a relatively large support width b' as viewed in the direction of the eye axis 9. It can be a little smaller than half the support distance a at most.
  • the theoretical maximum is half the support spacing a minus half the binding tape width b'.
  • the support width b' can be 40 cm.
  • the coil 4 initially rests on the supports 11 in such a way that the edge regions of the lateral surface 7 of the coil 4 adjoining the two end faces 6 rest on adjacent supports 11 .
  • the corresponding first partial area thus contains the edge areas of the lateral surface 7 of the coil 4 adjoining the two end faces 6.
  • those binding straps 5 which are located outside the two edge areas of the coil 4 are removed.
  • all binding straps 5 can be removed, the middle of which is at a distance from the left end face 6 of between 24 cm and 76 cm. In the in the 9 and 10 The example shown can thus be removed, for example initially only the middle binding tape 5 .
  • the coil 4 is then in accordance with 10 on the supports 11 in such a way that the central area of the coil 4 rests on the supports 11 .
  • the central area of the coil 4 is that area which is spaced apart from both end faces 6 .
  • the central area preferably contains in particular that area which is equally spaced from both end faces 6 .
  • the corresponding second partial area contains the central area of the lateral surface 7 of the coil 4, which is spaced apart from the two end faces 6.
  • all binding straps 5 can be removed, the center of which has a distance of less than 28 cm from one of the two end faces 6.
  • binding straps 5 can be removed whose center is at a distance of less than 26 cm from one of the two end faces 6 . in the in 9 and 10 The example shown can now be removed, for example, the two outer binding straps 5.
  • the increment is therefore exactly or at least about half as large as the support distance a.
  • all binding straps 5 can thus be removed in two consecutive steps. This is over 11 can be seen, in which those areas denoted by I and II are located in which the binding bands 5 are in the state according to FIG 9 and in condition according to 10 can be removed. As can be seen, the areas in their entirety cover the coil 4 without gaps over its entire width B.
  • the order in which the coil 4 rests on the supports 11 can of course also be reversed. So it can be the state according to first 10 be accepted and thereafter the state according to 9 .
  • the procedure according to 9 and 10 has the advantage in both cases that a plurality of coils 4 can be transported sequentially one after the other through the removal system, that is to say that, for example, one coil 4 is always transported from the left and away to the right.

  • This configuration differs from that described above in connection with FIG 4 to 8 and 9 through 11, respectively, by matching the design of the supports 11 and the manner in which the coil 14 rests on the supports 11. The other statements are still valid.
  • this can alternatively be carried out while the coil 4 rests with the first partial area on the first support 10 or with the second partial area on the second support 15 .
  • the coil 4 initially lies on the first support 10 with the first partial area of its lateral surface 7 .
  • the first partial area extends again only over part of the circumference of the coil 4 and also viewed in the direction of the eye axis 9 only over part of the coil width B.
  • the first support 10 can have two supports 11 which in turn have a respective support width b′ as seen in the direction of the eye axis 9 and are spaced apart from one another by a predetermined support spacing a when viewed in the direction of the eye axis 9 .

If, for example, the coil 4 is placed centrally on the supports 11, so that a coil center axis 16 is equidistant from both Supports 11 is removed, so in this state all binding tapes 5 can be removed, which are arranged outside of the areas defined by the two supports 11 (plus the binding tape width b). In the specific embodiment according to the 12 and 13 this is only the middle tie 5. 13 Fig. 12 shows this state in which the center binding tape 5 is removed.
  • the second support 15 can be designed, for example, as a single support that extends over a specific length as seen in the direction of the eye axis 9 .
