Definitions
- the present invention is based on a removal method for binding tapes from a coil produced by reeling a tape, the coil having two end faces and a lateral surface and a coil eye with an eye axis and the binding tapes having a binding tape width.
- the present invention is also based on an Ent removal system for removing binding tapes from a coil produced by reeling a tape, the coil having two end faces and a lateral surface and a coil eye with egg ner eye axis.
- a finish-rolled strip is usually reeled into a coil and transported in this form from a finishing train to a further system in which the coil is reeled off again and the strip is then fed to 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 prior pickling. Other systems are also possible.
- the coil is tied with binding straps that run around the outer surface of the coil.
- the binding straps must be removed again before further processing in the further system. to be removed.
- the binding tape is preferably removed automatically.
- the coil is positioned on a pair of ground rollers for this purpose, the ground rollers being tapered in those areas in which the binding strips of the coil run. This makes it possible to automatically split the binding bands and then automatically pull them off the coil.
- the binding straps in the entrance area of the further system can be separated, but not pulled off the coil, since the binding straps are clamped between the coil and the floor rollers. Rather, the ties must be removed manually in this case. This is time-consuming and cumbersome.
- the document DE331577A shows a device for severing and removing a binding tape.
- the object of the present invention is to create possibilities by means of which an automated removal of binding tapes is possible regardless of their positioning on the coil.
- the object is achieved by a removal method for binding tapes from a coil produced by reeling a tape with the features of claim 1.
- Advantageous embodiments of the removal process are the subject matter of the dependent claims 2 to 6.
- a removal method for binding tapes is designed in such a way that a) initially, while the coil rests with a first portion of its lateral surface on a first support, viewed in the direction of the eye axis, those binding tapes are removed which, when viewed in the direction of the eye axis, the coil completely outside of the first sub-area to give, and b) that then, while the coil is seen in the direction of the eye axis with a second sub-area on the first support or a second support, the first and the second sub-area seen in the direction of the eye axis at least around the Binding tape are spaced apart from one another, those binding tapes are removed that have not yet been removed in step a).
- the removal of the binding straps is often integrated into the transport of the coil from an entrance area of a further installation to a processing area of the further installation.
- the coil is transported from the entrance area of the further system to the processing area of the further system in that the coil is moved by means of a step bar in several stages in an essentially horizontal conveying direction from a first fixed saddle area to a second fixed saddle area, and the second fixed saddle area is promoted to a third fixed saddle area, etc. up to a last fixed saddle area, so that the coil rests alternately on one of the saddle areas and the crotch bar.
- a predetermined one of the saddle areas corresponds to the first support
- the crotch bar to the corresponds to the second edition
- step a) is carried out while the coil rests on the predetermined saddle area
- step b) is carried out while the coil is conveyed by means of the step bar from the predetermined saddle area to the subsequent saddle area.
- the crotch bar corresponds to the first edition
- a predetermined one of the saddle areas corresponds to the second edition
- step a) is carried out while the coil is conveyed from the previous saddle area to the predetermined saddle area by means of the step bar
- step b) is carried out while the coil is resting on the predetermined saddle area.
- the first sub-area contains the edge areas of the circumferential surface of the coil adjoining the two front sides and the second sub-area contains a central area of the coil spaced from both front sides.
- the coil is supported “outside” in step a) so that the binding tapes arranged “inside” can be removed automatically, and then “inside” in step b) so that the binding tapes arranged “outside” are automatically ent can be removed.
- the reverse procedure is also possible, so that the first sub-area contains the central area of the coil and the second sub-area contains the two edge areas of the coil.
- Other procedures are also possible, for example that the coil is supported in steps a) and b) once on the outside left, in the middle and on the right outside and once half left and half right.
- the eye axis can be oriented essentially orthogonally to the conveying direction. This is in contrast to the state of the art, in which the eye axis is mostly ori ented in the conveying direction.
- This procedure has the particular advantage that at the transition to the processing area of the further installation, the coil does not rotate 90 ° vertically running axis must be rotated, but can be processed further directly.
- configurations are also possible in which the eye axis is essentially oriented 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 to a vertical plane containing the eye axis. This can prevent the coil from "jumping open” after loosening and removing the tie straps, that is, the outermost turn from the coil loosens.
- a diameter of the coil is determined by measurement. This can be particularly useful in order to adapt subsequent machining operations as a function of the diameter.
- the diameter is preferably determined while the coil rests with the first sub-area on the first support in step a) and / or rests with the second sub-area on the first or second support in step b).
- a removal system of the type mentioned is designed in that
- the removal system has either a first edition or the first edition and additionally a second edition
- the first support is designed in such a way that, at a first point in time, the coil can rest on a first support with a first partial area of its outer surface
- first support or the second support is designed such that the coil to one after the second point in time, seen in the direction of the eye axis, lying at the first point in time, can rest with a second portion of its lateral surface on the first support or on the second support
- first and the second sub-area are spaced apart from one another as seen in the direction of the eye axis and
- the removal system has a removal device by means of which the coil, seen in the direction of the eye axis, can be removed completely outside the first sub-area surrounding binding bands, while the coil rests with the first sub-area of its outer surface on the first support, and the rest of the coil surrounding binding strips can be removed while the coil rests with the second part of its outer surface on the first or second support,
- the removal system has a first fixed saddle area, a second fixed saddle area, etc. up to a last fixed saddle area,
- the removal system has a step bar by means of which the coil can be conveyed in a substantially horizontal conveying direction in several stages from the first fixed saddle area to the second fixed saddle area, from the second fixed saddle area to the third fixed saddle area, etc. to the last fixed saddle area so that the coil rests alternately on one of the saddle areas and the crotch bar while it is being conveyed,
- the predetermined saddle area corresponds to the second support
- the removal device can be operated at least in the area of the predetermined saddle area.
- Many advantageous refinements correspond to those of the method. It can therefore often be referred to the above Ausry ments.
- the removal of the binding straps is included in the transport of the coil from an entrance area to a processing area of a further system, it is possible that a predetermined one of the saddle areas corresponds to the first support and the crotch bar corresponds to the second support. Alternatively, it is possible that the crotch bar corresponds to the first edition and the predetermined saddle area corresponds to the second edition. In both cases, it may 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 straps are removed, can in particular be designed as a robot.
- the removal device preferably has an optical detection device for detecting the binding straps surrounding the coil. This enables the binding straps to be recorded in a particularly simple and reliable manner.

- a metal strip 1 is rolled ge in a rolling mill. Only the last roll stand 2 of the rolling installation is shown. After rolling, the metal strip 1 is reeled into a coil 4 by means of a reel installation 3. The reeled coils 4 are then provided with binding tapes 5 (see FIG. 2) and removed from the rolling mill.
- FIGS 2 and 3 show a coil 4 after binding.
- the coil 4 essentially has a cylindrical shape. According to FIG 2 and 3, the coil 4 thus has two end faces 6 and one face 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 on the jacket surface 6 around the coil 4. They have a binding band width 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 ties 5 can be as required. Usually it is between one and four. According to the illustration in FIG. 2, for example, three binding tapes 5 can be present.
- the coil 4 initially rests on a first support 10 with a first partial area of its lateral surface 7, as shown in FIG.
- the first sub-area extends in the circumferential direction around the eye axis 9 - of course - only over part of the circumference of the coil 4. Above all, however, the first sub-area extends only over one area, as shown in FIG 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 distance a as seen in the direction of the eye axis 9 .
- the two supports 11 can have a support width b 'of 10 cm and be spaced from one another by 50 cm.
- the numerical values mentioned are of course to be understood purely as examples.
- first those ties 5 can be removed in accordance with the illustration in Figure 5 by means of a removal device 12, which in the direction of the Au- seen in the general axis 9, the coil 4 is completely surrounded outside of the first sub-area. If, for example, the coil 4 rests on the supports 11 in such a way that the end face 6 on the left in FIG.
- the Bin debandbreite b is 4 cm, all binding tapes 5 can be removed in this state, the center of the left end face 6 has a distance that is either between 17 cm and 53 cm or larger than 67 cm. As a precaution, a certain tolerance can still be taken into account, so that, for example, only binding tapes 5 are removed whose center is at a distance from the left end face 6 that is either between 19 cm and 51 cm or greater than 69 cm.
- FIG. 5 shows this state in which the two aforementioned binding tapes 5 have been removed.
- the second sub-area like the first sub-area, extends circumferentially around the eye axis 9 only over part of the circumference of the coil 4. Above all, however, the second sub-area extends in the direction of the eye axis 9 as shown in FIG likewise only over part of the coil width B. It is decisive that the first and the second sub-area, viewed in the direction of the eye axis 9, are spaced apart from one another by at least the binding tape width b.
- the coil 4 can rest on the supports 11 in such a way that the right end face 6 in FIG.
- binding tapes 5 can now be removed, the center of which is at a distance from the left end face 6 that is either less than 33 cm or between 47 cm and 83 cm. As a precaution, a certain tolerance can again be taken into account, so that, for example, only binding strips 5 are removed whose center is at a distance from the left forehead 6 that is either less than 31 cm or between 49 cm and 81 cm. 7 shows the state in which the remaining binding tapes 5 are also removed.
- FIG. 8 illustrates this again.
- the coil 4 and its binding straps 5 are shown in FIG.
- those areas of the lateral surface 7 are shown in Figure 8, from which the binding tapes 5 can be removed ent in the first and second state.
- the areas for the first state are denoted by I in FIG. 8, the areas for the second state with II. It can be seen that the areas in their entirety cover the coil 4 without any gaps over its entire width B.
- the removal of the binding tapes 5 as such can be carried out in the same way as in the prior art.
- the associated removal device 12 - that is, the device which removes the binding tapes 5 from the coils 4 - can thus be designed as required be.
- the removal device 12 can be configured as a robot.
- a control device 13 for the removal device 12 (usually a numerical control) is given the positions of the binding tapes 5 on the coil 4 by an operator or is otherwise known.
- the removal device 12 has an optical detection device 14 by means of which the binding tapes 5 surrounding the coil 4 are automatically detected.
- the optical detection device 14 can be designed as a laser scanner, for example.
- the optical acquisition device 14 transmits the data it has acquired (for example 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 within the framework of the Activation of the removal device 12.
- a measuring device 12 ′ is preferably also assigned to the distance device 12.
- the coil diameter D 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 on the first support 10 alternatively with the first partial area or with the second partial area.
- FIGS. 9 and 10 A further possible embodiment of the removal system according to the invention is explained below in conjunction with FIGS. 9 and 10.
- This configuration differs from the removal system explained above in connection with FIGS. 4 to 8 by the coordination of the configuration of the supports 11 and the manner in which the coil 14 rests on the supports 11.
- the other statements are still valid.
- the supports 11 form a sequence of supports 11.
- the supports 11 have a relatively large support width b ′, as seen in the direction of the eye axis 9. It can be a little less than half the column spacing a.
- the theoretical maximum is half the column 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 jacket surface 7 of the coil 4 adjoining the two end faces 6 rest on adjacent supports 11.
- the corresponding first sub-area thus contains the edge areas of the jacket surface 7 of the coil 4 adjoining the two end faces 6.
- those binding tapes 5 which are located outside the two edge areas of the coil 4 are removed.
- all binding tapes 5 can be removed, the center of which is at a distance of between 24 cm and 76 cm from the left end face 6.
- the middle bin deband 5 can be removed.
- the coil 4 according to FIG. 10 then rests on the supports 11 in such a way that the central region of the coil 4 rests on the supports 11.
- the central area of the coil 4 is that area which is spaced apart from the two end faces 6.
- the central area preferably contains in particular that area which is spaced the same distance from both end faces 6.
- the corresponding second Operabe rich contains the spaced from the two end faces 6 with central area of the lateral surface 7 of the coil 4. In this state the remaining ties 5, which have not yet been removed, are removed. With the above numerical examples, it is thus possible to remove all binding tapes 5 whose center is at a distance of less than 28 cm from one of the two end faces 6.
- Bin deb any Bin deb selected 5 can be removed, the center of one of the two end faces 6 has a distance that is less than 26 cm. In the example shown in FIGS. 9 and 10, for example, the two outer binding tapes 5 can now be removed.
- the step size is therefore exactly or at least about half as large as the column spacing a.
- all binding tapes 5 can thus be removed in two successive steps. This can be seen from FIG. 11, in which those areas, denoted by I and II, are drawn in, in which the binding tapes 5 in the state according to FIG. 9 and in the state according to FIG. 10 can be removed. It can be seen that the areas in their entirety cover the coil 4 without any gaps over its entire width B.
- the order in which the coil 4 rests on the supports 11 can of course also be reversed.
- the state according to FIG. 10 can therefore be assumed first and then the state according to FIG. 9.
- the procedure according to FIGS. 9 and 10 has the advantage in both cases that several coils 4 can be transported sequentially through the removal system, that, for example, a coil 4 is always transported from the left and is transported away to the right.
- the same support 10 is used for both states in which the respective coil 4 rests with a partial area on a support, ie the first support 10 according to the terminology of the present invention.
- the coil 4 is in the first state initially rests on a first support 11 and then in the second state on a second support 15 (see FIGS. 12 to 15).
- This procedure is explained in more detail below in connection with FIGS. 12 to 15.
- This configuration differs from the removal systems explained above in connection with FIGS. 4 to 8 or 9 to 11 by the coordination of the configuration of the supports 11 and the manner in which the coil 14 rests on the supports 11. The other statements are still valid.
- the metrological detection of the coil diameter D is concerned, 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 rests on the first support 10 with the first partial area of its lateral surface 7.
- the first sub-area extends in the circumferential direction around the eye axis 9 again only over part of the circumference of the coil 4 and also over only part of the coil width B seen in the direction of the eye axis 9.
- the first support 10 can have two supports 11 as before aufwei sen, which in turn, viewed in the direction of the eye axis 9, have a respective support width b 'and, viewed in the direction of the eye axis 9, are spaced apart from one another by a predetermined support distance a.
- the two supports 11 can have a support width b ′ of 30 cm and be spaced from one another by a support spacing a of 90 cm.
- the numerical values mentioned are again to be understood purely as examples.
- binding tapes 5 can first be removed by means of the removal device 12 that surround the coil 4 completely outside the first sub-area 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, all binding tapes 5 can be removed in this state, 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 FIGS. 12 and 13, this is only the middle binding band 5.
- FIG. 13 shows this state in which the middle binding band 5 has been removed.
- the second Aufla ge 15 can, for example, be designed as a single support which extends over a certain length as seen in the direction of the eye axis 9.
- the length of the second support 15 must be selected so that it is smaller than the support spacing a of the two supports 11 minus twice the binding tape width b and additionally minus the support width b '.
- the second support 15 may extend a maximum of 62 cm in the direction of the eye axis 9.
- the value will be selected to be lower, so that the second support 15, viewed in the direction of the eye axis 9, extends, for example, over 40 cm or 50 cm.
- the coil 4 rests successively on supports 10, 15 that are different from one another, namely on the first support 10 and on the second support 15, while the coil 4 in the procedure according to FIGS. 9 to 11 rests both times on the same support 10, namely on the first support 10.
- the removal of the binding tapes 5 is incorporated in the transport of the coils 4 from an input station 17 to a further processing station 18 as shown in FIGS. 16 and 17.
- a transport aisle from the input station 17 to the processing station 18 has several saddle areas 19.
- the Sattelbe rich 19 are fixed. They are arranged one behind the other as seen in a conveying direction x.
- the conveying direction x is generally horizontal or at least essentially horizontal.
- the saddle areas 19 each have two support areas 20 which are spaced apart from one another in an orthogonal to the conveying direction x, also horizontal or at least essentially horizontal transverse direction y.
- the saddle areas 19 have - calculated in each case from the center of the respective saddle area 19 to the center of the subsequent saddle area 19 at a distance a '.
- the corresponding coil 4 is first placed on the foremost Sat tel Scheme 19, for example by means of a crane (not shown), i.e. on the saddle area shown on the left in FIGS. 16 and 17 19. Then the coil 4 is conveyed by means of a step bar 21 from this saddle area 19 to the next saddle area 19 and so on up to the rearmost saddle area 19.
- the crotch bar 21 is seen in the transverse direction y between the support areas 20 of the saddle rich 19 is arranged.
- the step size of the step bar 21 corresponds to the distance a 'of the saddle areas 19 from one another.
- the step bar 21 is therefore lifted so that it lifts the coils 4 that rest on the saddle areas 19. This is indicated in FIG. 16 by an arrow PI.
- the coils 4 are now on the step bar 21.
- the step bar 21 is moved to the right. This is indicated in FIG. 16 by an arrow P2.
- the addition a ' is intended to indicate that the step bar 21 is moved to the right by its step size.
- the crotch bar 21 is lowered so that the crotch bar 21 lowers the coils 4, which rest on it, onto the saddle areas 19.
- the coils 4 have thus been passed on by one saddle area 19 each.
- the lowering is indicated in FIG. 16 by an arrow P3.
- the coils 4 now rest on the saddle areas 19 again.
- the step bar 21 is moved to the left. This is indicated in FIG. 16 by an arrow P4.
- the addition a ' is intended to indicate that the step bar 21 is moved to the right by its step width.
- the coil 4 is thus conveyed by means of the step bar 21 in the conveying direction x in several stages from the first saddle area 19 to the second saddle area 19, from there to the third fixed saddle area 19 and so on to the last saddle area 19.
- the coil 4 is conveyed further by the distance a '.
- the coil 4 rests on the crotch bar 21. In between, the coil 4 rests on one of the rich 19 saddles.
- the support areas 20 of one of the saddle areas 19 with the supports 11 of the embodiment according to FIGS. 12 to 15 and thus the corresponding Sat tel area 19 with the first support 10 can correspond.
- the crotch bar 21 can correspond to the second support 15 of the embodiment according to FIGS. 12 to 15. It is therefore possible in the embodiment according to FIGS. 16 to 18 to first remove the binding tapes 5, which are arranged relatively far inside, while the coil 4 rests on one of the saddle areas 19. While the coil 4 rests on the crotch bar 21, that is, during the conveyance to the next saddle area 19, the remaining binding tapes 5 can then be removed.
- the crotch bar 21 can correspond to the first support 10, so that the first part of the binding tapes 5 is removed while the coil 4 rests on the crotch bar 21.
- the following saddle area 19 continues to correspond to the second support 15. In this case, the remaining binding straps 5 are removed while the coil 4 rests on this saddle area 19.
- the removal device 12 can only be operated in the area of the corresponding saddle area 19.
- the removal device 12 must follow the movement of the step bar 21.
- the movement of the crotch bar 21 is interrupted so that the crotch bar 21 is not moved during the period during which the coil 4 rests on the crotch bar 21 and part of the binding tapes 5 is removed. This procedure has the advantage that the activation of the removal device 12 does not have to be coordinated with the ongoing movement of the step bar 21.
- the eye axis 9 can be oriented parallel to the conveying direction x.
- the eye axis 9 is oriented orthogonally to the conveying direction x.
- the metal strip 1 reeled into the coil 4 has, as shown in FIGS. 2 and 3, a band head 22, al so the last reeled piece of the metal band 1.
- the removal device 12 is preceded by a rotating device 23.
- the rotating device 23, as shown in FIG. 17, may be part of the Sat tel Siemens 19, which is arranged immediately upstream of that saddle area 19 at which a part of the binding straps 5 is removed.
- at least one other saddle area 19 can be arranged between the saddle area 19, which has the rotating device 23 as a component, and the saddle area 19, from which part of the binding straps 5 is removed.
- the coil 4 is rotated about its eye axis 9, so that the tape head 22 has a predetermined orientation to a vertical plane, which in turn holds the (horizontally oriented) eye axis 9 ent.
