Definitions

  • This invention relates in general to strip material coiling and uncoiling devices, and in particular to a new and useful device for taking up, removing the coiling curvature and feeding off strip material from a coil thereof.
  • the present invention is particularly applicable to the unwinding of metallic strip material from a coil, and in particular to the unwinding of rolled sheet metal strip.
  • the invention includes two rollers between which the strip material is guided and which are adjustably mounted on a linkage.
  • the linkage is such that the upper roller may roll off on the lower roller in a plurality of different positions of height and location when the strip to be unwound is present between them.
  • an object of the invention to provide an improved device for the taking up of coiled strip or sheet material from a roll thereof and for adjusta'bly engaging the strip material so that it may be straightened as it is fed to a further device such as a straightening machine.
  • a further object of the invention is to provide a device for the taking up and unwinding of strip material from a coil thereof which includes a linkage mechanism for adjustably positioning upper and lower rollers between which the coil strip material may be fed and for moving the rollers so that they are oriented in respect to each other in a desirable manner for feeding the strip material therebetween.
  • a further object of the invention is to provide a device for receiving, preparing and passing on a strip material from a coil which includes two adjustably mounted rollers between which the coil is to be fed and a wedge member over which the sheet material is to be directed with means for adjusting the position of the parts for receiving the coiled strip material.
  • a further object of the invention is to provide a device for facilitating the unwinding of coiled strip material which is simple in design, rugged in construction and economical to manufacture.
  • FIG. 1 is a somewhat schematic side elevational view of a strip material unwinding device constructed in accordance with the invention.
  • FIG. 2 is a view similar to FIG. 1 but indicating the parts in an advanced position.
  • the invention embodied therein is shown in association with the unwinding of strip material which is wound into a coil 10, which coil is rotatably mounted.
  • the coil 10 is arranged for being driven by an auxiliary roller 15 which is pressed against its periphery and which itself is driven, for example, by an electric motor (not shown).
  • the auxiliary roller 15 is pressed against the periphery of the coiled strip material which is being unwound and it prevents the springing open of the turns of the coil when the bindings originally holding the coil together have been untied.
  • a device for facilitating the unwinding of a strip material from the coil 10 which includes a roller 6 having a shaft 5 which is rotatably mounted.
  • the shaft 5 is rotatably supported ateach end in bearings which rest at the end of a pair of post elements 13, 13, only one of which is indicated in the drawings.
  • the post elements 13 are pivotally mounted at their lower ends in bearings 28 which are mounted on the floor or other support.
  • the opposite end of the cylinder 14 is pivotally mounted at 17 on a fixed support such as a wall element.
  • All of the other parts of the device to be described are indirectly or directly connected to the shaft 5.
  • the rod 12 By suitable control means connected to the cylinder 14 the rod 12 is shifted in either direction as indicated by arrows 18' for the purpose of pivoting the post member 13 about its pivotal mounting 28 with all of the remaining mechanism toward or away from the coil 10.
  • Aflixed to the shaft 5 is a relatively long and wide wedge member 11 which is mounted on and substantially coextensive in width with the roller 6.
  • a pair of lever arms 3, 3 (one being shown) is secured to respective ends of the shaft 5 and are pivotally connected at their outer ends at the location of pivot or axle 1 to a reciprocating piston rod member 19 which, in turn, is secured to a piston (not shown) which is slidable in a pressure cylinder 7.
  • the pressure cylinder 7 is advantageously hydraulic or pneumatic and is pivotally mounted at 9 on a bracket secured to the floor or other support.
  • a further pair of lever arms 4, 4 are secured at one of their ends to shaft 20 of a roller 8 and pivotally connected at their inner ends to the reciprocating piston rod 19 at the location 1.
  • At least one of the lever arms 4 is connected pivotally to a reciprocating rod member 22 at the location of the pivot or axle 21.
  • the rod member 22 is secured to a piston (not shown) which is reciprocable in a pressure cylinder 2.
  • the cylinder 2 is pivotally carried by one of the lever arms 3, 3 on a pivot bracket 30 for pivoting about axis 32.
  • the cylinder 2 is movable with the arm 3. Movement of the piston rod 22 to shift the pivot point 21 will adjust the position of the roller 8 in accordance with the arrows indicated at 26.
  • a stationary guide table 23 over which the strip 24 which is drawn off from the coil 10 is directed.
  • the material is guided over the table 23 and into a straightening machine 25.
  • the unwinding device When a strip beginning is to be unwound from a coil 10, the unwinding device is located at first at a location away from the coil, that is, with rollers 6 and 8 moved to a spaced location therefrom as indicated in FIG. 2. The strip material is then directed under the roller 8 as indicated and into the straightening machine 25.
  • the post parts 13 are pivoted counterclockwise by means of the hydraulic cylinder 13.
  • Control means are provided to move the piston rod 19 of the hydraulic cylinder 7 to cause the entire unit to be pivoted about the axis in a clockwise manner or counterclockwise manner, as indicated by the arrows 27.
  • the wedge 11 rises from the position indicated in FIG. 1 to the position indicated in FIG. 2.
  • the roller 8 is lifted off the roller 6 when the piston rod 22 of the pneumatic cylinder 2 is extended.
  • the lever arm 4 is pivoted about the shaft 1 to assume the position indicated in FIG. 2.
  • the parts are moved from the position indicated in FIG. 2 to the position indicated in FIG. 1 by moving the piston rod 12 toward the coil to cause pivoting of the post 13 about the pivot 28 until the extreme edge of the wedge member 11 applies against the coil.
  • the vertical position of the edge of the wedge can be corrected by the hydraulic cylinder 7 by pivoting the wedge 11 by the rotation of the shaft 5 due to the rotation of the lever arm 3 thereabout.
  • the wedge 11 is preferably made at least as wide as the strip 24.
  • the driving roller 15 pressed against the coil from above will be rotated until the strip beginning slides over the cutting edge of the wedge 11 and along the surface thereof. The strip will not lie flat and smooth but will be arched upward as it was coiled previously.
  • the coil 10 is stopped so that the movement of the strip beginning ceases.
  • the roller 8 is then lowered by retracting the piston rod 22 via the cylinder down onto the roller 6 and clamps the strip beginning.
  • both the roller 6 and the auxiliary roller 15 may contribute to the further drive but this is not necessary. If the roller 15 is still permitted to run but the roller 6 draws off the strip faster than the drive of the auxiliary roller, this may be taken into account by a freewheeling arrangement at the auxiliary roller 15.
  • the strip runs out approximately straight and no longer curved.
  • the strip runs between the rollers 6 and 8 in the direction of a guide table 23.
  • the direction of the moving strip beginning can be selected so that it reaches the guide table correctly.
  • the device according to the invention can be taken out of operation. This is done by moving the roller 8 upwardly again to the position indicated in FIG. 2 by actuating rod 22 through cylinder 2.
  • the lower roller 6 is then no longer touched by the strip because it will lie in a location lower than the tension cross of the strip 24 between the coil 10 and the machine 25.
  • the drive units comprising the fiuid cylinders 2, 7 and 14 may be of any fluid pressure type such as pneumatic.
  • the drive units described as pneumatic cylinders may be replaced by hydraulic cylinders and vice versa.
  • spindle drives operated by electric motor, as for example in the place of the hydraulic drive '7, 19.
