Definitions

  • a second form of previous strip uncoiling apparatuses consisted of a unitary coil box and drag-type uncoiler wherein the coil engaging disks of the coil box and the coil supporting cones of the uncoiler were arranged to rotate about a common axis and the cones were retractable through openings formed in'the disks of the coil box.
  • the disks of the coil box and the "cones of the uncoiler were provided with separate traversing means. It must be pointed out that this machine has not proven to be altogether effective in handling tightly wound coils.
  • the openings provided in the disks each other. This arrangement, obviously, in addition to being quite expensive, had the additional serious disadvantage of involving considerable lost time in effecting the substitution of the machines.
  • a unitary coil box and drag-type uncoiler apparatus in which at least one of the disks of the coil box and one of the expandable mandrels of the uncoiler are traversable by the same means.
  • a combination coil box and drag-type uncoiler apparatus wherein the disks of the coil box are readily movable to inoperative positions when not in use, but which, when in their operative positions, are adapted to be supported and traversed by the expandable mandrels of the uncoiler.
  • the present invention also provides a novel arrangement of at least two different length coil supporting members, which may be alternatively brought into an operative portion for supporting coils of different widths so that all coils may be adequately supported for a given range of widths.
  • a coil lift is provided which cooperates with the aforesaid members for positioning a coil relative to the mandrels of the drag-type uncoiler.
  • FIGURE 1 is an elevation view partly in section of an apparatus according to the present invention employed as a coil box;
  • FIGURE la is a partial elevational view of the apparatus shown in FIGURE 1 employed as a drag type uncoiler;
  • FIGURE 2 is a section view taken on lines II-II of FIGURE 1;
  • FIGURE 3 is a section View taken on lines III-Il1 of FIGURE 1.
  • the machine comprises a unitary coil box drag-type uncoiler, the former being employed to uncoil loosely formed coils and the latter for tightly formed coils.
  • the drawings illustrate the machine set up to be used as a coil box for feeding strip to a rolling mill 9.
  • the coil uncoiling apparai 15 shown best in FIGURE 1.
  • This head 15 includes a motor, not shown, that drives a horizontally arranged drive shaft 16 to which is connected a motor pinion that meshes with a gear, the pinion and gear, while not being specifically shown, are received in a gear case 17, nor is there shown the spline shaft construction or extended portion of the shaft 16 that enables the head 15 to be traversed relative the drive shaft 16.
  • the mandrel is of a very wellknown design and may include in one form a plurality. of circular segments which are expanded and contracted by complementary-cooperative wedges by the agency of a piston cylinder assembly 20 secured at the drive shaft side of the head 15.
  • the tightly wound coils are uncoiled by the mandrel 19 so that the mandrels diameter is such that it will accommodate the substantially constant openings of the coils. Since the construction, arrangement and operation of the aforesaid elements are generally well known, a more detailed description thereof is deemed unnecessary.
  • the disk 22 thereof is shown in its operative position where it is freely rotatably supported by the expanded mandrel 19.
  • This construction is obtained by providing a non-rotatable sleeve 23 on mandrel 19 to which there is secured and arranged between the disk and the sleeve a bearing 24 that rotatably supports the disk 22.
  • the head including the mandrel 19, the piston cylinder assembly and the disk 22 are advanced by the operation of a piston cylinder assembly 21 which is connected to the lower portion of the head, as shown in FIGURES l and 2. In certain forms it may be necessary only to traverse one of the units 11 and 12.
  • FIGURES 2 and 3 there is secured to it an arm 25 that extends toward the right-hand side of the uncoiler unit 12 as one views these figures, at which .end there is provided a sleeve 26 which is carried by a transversely arranged equalizing shaft 27, the shaft being supported in the frame 13 of the uncoiling apparatus.
  • the construction of the sleeve 26 and the shaft 27 is such that the sleeve is permitted to move axially and angularly relative to the shaft as indicated by the clearance between these members as shown in FIGURE 2.
  • the arm 25 has a rib 28 which passes between the fingers of a bifurcated member 29, when the disk 22 is moved to its maximum outward position.
  • the member 29 is made as an integral part of a sleeve 31, shown best in FIGURE 2, which is mounted also on the shaft 27 and moves angularly relative thereto but not axially.
  • the bifurcated member 29 has a link 32, shown in FIGURE 3, which projects downwardly from the shaft 27 and is connected to the rod of a piston cylinder assembly 33.
  • the disk 22 is movable axially relative to the shaft 27 so that it is able to engage coils of the whole range of widths. To position the disk in its inoperative position, the disk is brought to its extreme outward position by a retraction of the head 15.
  • the piston cylinder assembly 21 can be operated to bring the mandrel 19 into engagement with a tightly wound coil. It will be observed that the mandrel 19 does not project through the disk 22 in order to engage the coil and as a result no central opening needs to be provided in the disk.
  • This construction has the advantage over previous designs of not requiring any change in the expanding mechanism of the drag-type uncoiler.
  • the disk being constructed to be freely rotatable on the sleeve 23 will have a low friction and inertia effect, since it does not have to rotate with the expandable mandrel 19. Conversely, the mandrel would not be subject to the inertia of the disk since, as explained previously, the disk will move to an inoperative position when the mandrel is being used to support coils.
  • a roller assembly 34 consisting of two parallelly vertically arranged spaced apart frames 35 between which are mounted two pairs of freely rotatable rollers 36 and 37, the pair of rollers 36 having narrow body portions in comparison with the body portions of the rollers 37, as can be seen in comparing the rollers in FIGURE 2.
  • the frames are trunnion mounted on a common shaft 38 with which they rotate.
  • an arm 39 is provided, having its lower end connected to the rod of a piston cylinder assembly 41 having a stroke sufficient to rotate the frames through an arc of approximately In this manner depending upon the particular width of the coil to be uncoiled, either pair of the rollers 36 or 37 can be brought into the coil supporting position.
  • FIGURE 1 shows the construction of individual locking assemblies 42 provided for each frame 35 to prevent inadvertent rotation of the roller assembly, which comprise retractable pins 43 connected to piston cylinder assemblies 44.
  • Each frame 35 is provided with two spaced apart holes, one hole of each pair lining up with each other and the pins 43 when either the rollers 36 or 37 are in the coil supporting positions.
  • Two pairs of feet 40 are provided for the roller assembly, which pairs engage alternatively one of two parallelly spaced apart beam-s 40a and by which means whether supported by the rollers 36 or 37 the weight of the coils is transferred to the foundation.
  • the invention also contemplates providing a coil lift 45 for positioning the coils coaxially with respect to the mandrel 19.
  • the coil lift is raised and lowered by a vertically arranged piston cylinder assembly 46.
  • the coil engaging portion of the coil lift is so constructed that it will pass between the spaces provided between the pairs of rollers 36 or 37 as best shown in FIGURE 3. It is important to note that since the disk 22 is not carried by the mandrel 19 as in previous apparatuses, the coil lift 45 can be made substantially long giving the advantage of an adequate supporting surface for the wider coils. It will be understood that in FIGURE 3, when the machine is being used as a coil box, the upper end of the lift 45 will be lowered from where it is shown in FIGURE 3 to allow movement of the disk.
  • the coil is transferred to the uncoiling apparatus by a means not shown, wherein a portion of its outer periphery will come into contact with the shock absorbing rollers 30 and displace them against the pressure of the piston cylinder assembly 3012 which will dissipate the The coil will eventually come to rest upon the rollers 36.
  • the piston cylinder assemblies 21 of the respective units 11 and 12 will-be operated to advance vertical surfaces of the coil. It is normally the practice to separate and prepar'e'the leading end of the coilprior to it being transferred to the coil box so that once the disks are positioned, the coil is ready to be fed immediately to the mill.
  • the first order of operation would be to retract the disks 22 to their inoperative positions. This is accomplished by operating the piston cylinder assemblies 21 for units 11 and 12 to bring the mandrels 19 and the disks 22 to their retracted positions where the ribs 28 will pass into the fingers of the bifurcated members 29. The piston cylinder assemblies are then operated to collapse the mandrels 19 whereby upon further operation of the piston cylinder assemblies 21, the mandrels 19 are retracted from the sleeves 23. Upon this occurring, the piston cylinder assemblies 33 will be operated to rotate the arms in a counter-clockwise direction which will bring the disks 22 to the outline position shown in FIGURE 3.
  • the uncoiler is now ready to receive the tightly wound coil which will be positioned on the rollers 36 as previously explained.
  • the piston cylinder assembly 41 will be operated to place the axis of the coil in line with that of the mandrels 19 following which the piston cylinder assemblies 21 will be operated to bring the mandrels 19, although not the disks, into a position where the mandrels will protrude into the open ings of the coil, Once this has been accomplished, the mandrel will be expanded to grip the coil.
  • said disks being constructed and arranged to be brought from an operative position, wherein the disks are rotatably supported by said mandrels and positioned so that their surfaces may be contacted by a coil, to an inoperative position, wherein said disks will be positioned away from said mandrels and coil and vice-versa, and
  • An apparatus including means for supporting a portion of the periphery of a coil when the coil is located between said mandrels,
  • said disks having portions engageable by said cooperative mandrels on the expansion of the latter for rotatably supporting the disks and for causing the mandrels to move the disks axially toward and away from the sides of a coil,
  • said disks being constructed and arranged to be brought from an operative position, wherein the disks are rotatably supported by said mandrels and positioned to be contacted by a coil, to an inoperative position, wherein the disks will be positioned away from said mandrels and coil and vice-versa, and
  • the means for moving said disks includes means for controlling the movement thereof to position said disks for engagement by said mandrels.
  • each of said arms includes a first engageable member
  • first and second en ageable members secured to said support, said first and second members being brought into engagement with and disengagement from each other upon movement of said mandrels.
  • said means including a first coil supporting member having a coil supporting surface of a given length and a second coil supporting member having a coil supporting surface of a length different than the length of said first coil supporting surface,
