United States Patent Office 3,441,234 Patented Apr. 29, 1969 3,441,234 REELING-OFFAPPARATUS FOR USE IN CONNEC- TION WITH ONE-WAY ROLLING MILLS Ernst Heinrich Barten, Buschhutten, Germany, assignor to Achenbach Sohne G.m.b.H., Siegen, Germany Filed July 20, 1965, Ser. No. 473,394 Int. Cl. B21c 1/00 US. Cl. 242-80 11 Claims The present invention relates to a reeling-off apparatus on one-way rolling mills for coreless coils and also for coils with a core formed by a reel, in which a turntable with two coil carriers located symmetrically thereon with regard to the center of said turntable is arranged ahead of the rolling stand.

Reeling-off apparatuses with a turntable ahead of the one-way rolling mill are known, in which the turntable has mounted thereon two symmetrically arranged coil carriers while the respective coil carrier which is remote from the rolling stand serves to receive and wind up material received fro another coil carrier which is arranged behind the turntable. The terms ahad of, behind and adjacent are meant with regard to the feeding direction of the material toward the rolling stand.

The heretofore known reeling off devices of the general type mentioned above require a special drive for the rewinding operation in addition to the customary withdrawing means.

It is, therefore, an object of the present invention to provide an improved and simplified reeling-off apparatus for rolling mills.

It is another object of this invention to provide a reeling-off apparatus for rolling mills, which will not re quire an additional drive for the rewinding of the coil nor additional withdrawing means behind the turntable.

These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawing, in which:

FIG. 1 is a side view partially in section of an arrangement according to the present invention.

FIG. 2 is a top view of the device shown in FIG. 1.

FIG. 3 is a section one line IIIIII of FIG. 2.

FIGS. 4 and 5 are side and plan views respectively, of a modification showing improvements in the journaling and drive of the turntable and also showing a cradle pertaining to one station of the turntable which is supported independently of the turntable.

The present invention which, as mentioned above, refers to a reeling-off apparatus on one-way rolling mills for coils with and without cores in which a turntable with two symmetrically arranged coil carriers is located ahead of the rolling stand, is characterized in that in longitudinal direction of the coil carriers adjacent the turntable there is provided an arm which is movable as to height, and which is also transversely movable and swingable, and which is provided with removing means for removing a coil thereon. Further, a braking device is provided for that coil carrier adjacent the rolling stand which is adapted to be coupled with the shaft of the re spective coil carrier in front of the rolling stand to control the said carrier.

The coil to be supplied to the rolling stand is received by the said transversely movable arm and together therewith is so tilted and moved laterally and in upward direction that the said arm will move to the level and into the direct vicinity of the expansion shaft of that coil carrier which is remote from the rolling stand. When the coil has been placed onto the expansion shaft of said coil carrier, the coil is opened and the start of the coil is trimmed by shears.

In order to assure that the coil to be placed upon the expansion shaft of that respective coil carrier which is remote from the rolling stand will adopt the desired position with regard to the longitudinal direction of the rollin gstand, each coil carrier is provided with removing means which simultaneously serves as counter hearing. It will be appreciated that in this Way, regardless of the width of the coil, the coil will always be placed into the desired position with regard to the longitudinal axis of the rolling stand. This removing means is also em ployed for removing empty reels from the expansion shaft and moving the same onto the transversely movable arm, if the operation is carried out with coils having a core.

Each coil carrier preferably comprises a coil support adapted to be raised and lowered and equipped with driven members. In addition thereto, each coil carrier has a coil opener. The drive of the coil support as well as of the transporting pair of rollers associated with each coil carrier is mounted on said turntable. In addition to the transporting rollers, depending on the thickness of the coil, a straightening or levelling path may be provided or one or more adjustable bending rollers.

Referring now to the drawing in detail, the arrangement shown therein comprises a rolling stand 1 and a turntable 2 which when looking in the feeding direction indicated by the arrow A (FIG. 2) is located in front of rolling stand 1. Mounted on turntable 2 and arranged symmetrically with regard to its center point M are two

coil carriers

3 and 4. When turning turntable 2 by in the direction of the arrow B or in opposite direction, always one coil carrier can be located directly in front of rolling stand 1, Whereas the other coil carrier will be located remote from said rolling stand 1.

Each

coil carrier

3, 4 has an expansion shaft 5, a coil opener 6 and a coil support 7 which is adapted to be moved upwardly and downwardly in the direction and opposite to the direction of the arrow C. Each

coil carrier

3, 4 also comprises driven rollers 8 and pivotally journalled transporting rollers 9 which, similar to rollers 8, may be driven by driving means on turntable 2. Each expansion shaft 5 has associated therewith removing means 10 which simultaneously serves as abutment for the coil placed upon the expansion shaft 5 in order to align the transverse central portion of the coil with the longitudinal central portion of rolling stand 1.

Each expansion shaft 5 has an extension 11 which through gears or the like is operatively connected with a stub shaft 12. Stub shaft 12 is adapted to be coupled to shaft 14 of a brake generator while the coil carrier occupies a position adjacent rolling stand 1. This brake generator is in longitudinal direction of that coil carrier which is adjacent the rolling stand 1 arranged stationarily adjacent the turntable 2. The brake generator comprises transmission gear 15 having the aforementioned shaft 14 and also having connected thereto a brake motor 25. Member 12a on

shaft

12 and 13 on shaft 14 etl'ect detachable driving connection of shaft 12 to shaft 14. Member 12a may be a splined end on shaft 12 while member 13 may be a splined sleeve reciprocable on shaft 14.

Behind turntable 2 and thus adjacent the respective coil carrier 3 which is remote from the rolling stand 1, there are provided shears 16 in the form of roller shears. These shears are arranged stationarily and if desired may be replaced by a sheet sheers or plate shears.

Also arranged adjacent turntable 2 is a guiding member 17 on which a rotatable frame part 18 is movable in the direction of the arrow D. On this rotatable frame part there is pivotally journalled a supporting member 19 which is adjustable as to height and carries a transversely movable arm 20. Supporting member 19 is provided with removing means comprising a piston and cylinder 21a and a pusher plate 21. It will thus be appreciated that arm 20 may from its dot-dash position shown in FIG. 2 be moved into the solid line position thereof and may be turned and adjusted as to height so that it can be aligned with the expansion shaft of the respective coil carrier which is remote from the rolling stand 1. In this way arm 20 can be aligned with expansion shaft 5 of the respective coil carrier which is remote from the rolling stand 1 so that coil W on arm 20 can by means of pusher plate 21 be moved onto expansion shaft 5 of said last mentioned coil carrier. After the coil opener 6 has been actuated and also

rollers

8 and 9 have been actuated, the coil start can be trimmed by shears 16.

FIG. 3 shows more in detail the construction of the turntable and the parts thereon. In this view it will be seen that turntable 2 has gear teeth or the like at 2a by means of which the turntable can be driven in rotation by suitable motor means (not shown )while support means 2b support and guide the turntable.

Arresting means, as shown schematically at 3:1, serve to locate the turntable in its two indexed positions. If the turntable indexes reversibly from one position to the other, simple abutment means will provide for the two turntable locations while if the turntable always indexes in one direction, arresting means 311 would include a retractible abutment element. FIGURE 3 also shows that shaft 5 has a radially movable portion 5b which can be pushed outwardly to engage the hole in a coil by movement of portion 5b along the cam-like member 5c in shaft 5, by the piston 5a connected to portion 511 by rod 5d. Spring means (not shown) could be employed to retract portion 5b.

The rollers 9 may be carried by arm means on a shaft 9a which is rotatable by motor 9b to press rollers 9 against the coil or to retract them from the coil.

The rollers 8, are connected with the drive motor 7b therefor by chain means 70. Rollers 8 and motor 7b are mounted in a carriage 7d which is vertically movable in frame 7e which is fixed to turntable 2. Fluid motor means 7a connected between frame 7e and carriage 7d is operable for effecting the said vertical movement of the carriage.

FIG. 3 also shows that shaft 5 carries gear means 5 which mesh with pinion means 12b on shaft 12 so shaft 5 can be placed under the control of the braking mechanism.

FIG. 3 further shows that the removing means comprises piston and cylinder means 33a and a pusher plate 33 on the piston. The pusher plate 33 can be positioned, as previously mentioned, by piston and cylinder means 33a so as to stop a coil placed on shaft 5 in the proper longitudinal position on the shaft.

In FIG. 3 it will be seen that support arm 20, which picks up new coils and places them on the turntable, is carried by a sleeve 31 that is vertically movable on a column 30 as indicated by the arrow F by a fluid motor 32. Column 30 is mounted on rotary base member 28 which has peripheral teeth engaged by a pinion 27 that is driven by a motor 29. Member 28 is rotatable about a pivot 26 and when motor 29 is energized, the member 28 and all parts supported thereon rotate as indicated by the arrow G. The entire assembly is slidable on stationary support means 32a so as to take the motion indicated by arrow D.

In operation, and with reference, in particular, to the modification of FIGS. 1-3, while the coil located on the expansion shaft 5 of that coil carrier 4 which is adjacent stand 1 moves into rolling stand 1, expansion shaft 5 of the coil carrier 3 which is remote from rolling stand 1 may be loaded with a new coil and the preparations therefor may be carried out, such as straightening, clamping and opening of the coil, the advance of the coil start and the trimming thereof. When these preparations concerning the coil on coil carrier 3 and the unrolling of the coil of coil carrier 4 have been completed, turntable 2 is rotated by after the rotatable frame part 18 has been moved back into its dot-dash line position. In this instance, it receives a new coil, whereas stub shaft 12 of coil carrier newly moved into the position adjacent rolling stand 1, is coupled with counter shaft 14 of the transmission by means of

member

12a, 13.

Each coil carrier may, as illustrated, comprise a straightening path including a plurality of rollers 22 or may have one or more adjustable bending rollers in addition to the transporting roller 9.

When coils are involved which have a reel as core, the operation is analogous. However, prior to placing a new coil through the intervention of arm 20 onto the respective coil carrier which is to be charged, the empty reel left on the coil carrier previously processed, has to be stipped otf expansion shaft 5 by a stripper 10 onto arm 20 and then has to be removed from the latter by means of the pusher plate.

Referring now to the modification of FIGS. 4 and 5, a turntable 42 is rotatably supported adjacent a rolling stand 41. The material feeds from the turntable to the rolling stand in the direction of arrow E. The turntable has coil supports 43, 44 symmetrically arranged with respect to center M of the turntable.

Turntable 42 is giuded by the king journal 45 and is additionally jornalled on rollers 46 along its marginal portion. The drive of the turntable may be effected by a gear ring 42a on the bottom of the turntable which is engaged by pinion 47 driven by a motor 48. The arrangement may be such that hook-shaped or similar arresting means 49 may be adapted to engage predetermined regions of the marginal portion of the turntable. Arresting mans 49, of which there are two, are hydraulically actuated by pistons arranged in cylinders 50 and are adapted to be brought into engagement with and out of engagement with said turntable to lock and release the turntable.

Turntable 42 carries one stationary bearing means 51, 52 each for each of the two coil supports 43, 44 while means may be provided for coupling that coil support which is located at the rolling stand to a brake means 53 arranged adjacent turntable 42 for purposes of producing a braking force on the coil. The end of each coil support opposite the stationary "bearing therefor is held by an arm 54 adapted to be tilted in outward direction to expose the end of the coil. Each coil support has, in addition to a coil opener associated therewith, rollers 55, '56 journalled in a frame 56a which is tiltable on tilting arm 57 which is capable of adapting itself to the changing size of the coil.

Turntable 42 is, underneath each

coil support

43, 44, provided with a passage 58, 59. Between the stationarily arranged motor 48 and the king support 45, i.e. in the region of the coil support remote from the rolling stand, there is provided a stationary box 60 in which there is guided a second box 61. This second box is under the influence of fluid motor 62 which is adapted to move a station or carriage 63 arranged in the upper portion of the second box 61 upwardly and downwardly, i.e. into the positions 63' and 63" and vice versa. For purposes of placing a coil on coil support 43 or for purposes of withdrawing an empty coil, carriage 63 may be movedin upward direction during which movement it may pass through passages 58 or 59, respectively.

The carriage 63 includes driven rollers 63a which are connected to a drive motor 63b. Rollers 63a thus perform the function of rollers 8 of the first modification and can, for instance supply power to draw in a web of metal and coil it up in station 43 preparatory to movement of the coil into position adjacent the rolling stand. These rollers also can drive a coil placed in station 43 during opening of the coil.

If it is intended to turn the turntable 42 with coil supports 43, 44, in order to move a coil placed on the coil support remote from rolling stand 41 into the position adjacent the rolling stand, it is necessary to move station 63 downwardly into the box 60.

The turntable according to the present invention with the parts arranged thereon is, due to the arrangement of station 63 which is independent of the turntable, lighter than heretofore known embodiments. In order to obtain an exact fixing of the working position and a proper support of the turntable with regard to the rolling stand, the turntable is provided with inclined marginal portions 64 arranged at recesses along the circumference of the turntable while the rolling stand is provided with corresponding small blocks 65 which, by means of fluid motor means 66, are movable along a guiding means 67 in upward and downward direction in such a way that each small block 65 is adapted to be moved from the position indicated in FIG. 4 in solid lines into position 65 indicated in dot-dash lines, and vice versa.

In the position indicated in solid lines, the small block assures that the turntable is braced with regard to the extension 68 fixed to the rolling stand. For purposes of turning the turntable, each block is brought in its disengaged position indicated at 65'. In view of the inclined marginal portion 64, the turntable is, in the vicinity of blocks 65, pressed onto the corresponding roller support 46a.

On that side which faces away from the rolling stand, the two cylinders 50 together with the arresting or clamp means 49 perform a corresponding bracing of the turntable against the supporting rollers 46 connected to the foundation.

The operation of the modification of FIGS. 4 and 5 is the same as described above for FIGS. 1-3 except for the carriage 63 in FIGS. 4 and 5 having the rollers 63a which is stationary instead of being movable with the turntable as in the case of the modification of FIGS. 1-3.

It is of course, to be understood that the present invention is, by no means, limited to the particular arrangement shown in the drawing but also comprises any modifications within the scope of the appended claims.
