Definitions

  • a pair of fixtures are movable longitudinally of the coil axis from a clearance position relative to the coil carrier to an operative position adjacent the ends of the coil, and are locked against separating movement.
  • Pressure pads mounted on one of the fixtures are movable into engagement with one end of the coil to compact the coil against the other fixture for the application of bands to the coil.
  • Means are provided on the fixtures for locating the coil carrier relative thereto, and the coil is supported or cradled from below prior to the application of the compacting force.
  • the apparatus is suitable for automatic operation.
  • This invention pertains to improvements in press type apparatus for compacting and handing annular coils of steel wire or rod, permitting this operation to be performed while the coil is suspended from a carrier of a conveyor.
  • apparatus of the first type has the disadvantage of the lost time required to return the carriage to initial position after each coil has been banded; while apparatus of the second type the disadvantage of the time and expense of handling and the likelihood that coils may be damaged or disarranged in handling, especially while being loaded into the apparatus prior to banding.
  • Another problem presented by the prior art is that of satsifactorily arranging, compacting and banding coils in a range of lengths, especially with apparatus of the first type where the operation is carried out with the coil suspended from a conveyor carrier.
  • the apparatus of the invention for compacting and banding a coil of wire suspended from a carrier, with the axis of the coil extending substantially horizontally includes a pair of fixtures suitably mounted on tracks or ways for linear movement toward and away from each other in a direction longitudinally of the coil axis.
  • Means such as fluid pressure cylinders are provided for relativel moving the fixtures between a clearance position relative to the carrier and an operative position relative to the coil, and a locking arrangement prevents separating movement of the fixtures in the operative position thereof.
  • the carrier is aligned with the fixtures by suitable locating means provided thereon.
  • the coil is cradled from below prior to and during the compacting operation to at least partially remove the weight of the coil from the carrier, eliminating sag and permitting optimum arrangement of the coil strands when compacted.
  • the locking device is capable of locating the fixtures and preventing separating movement thereof within a range of operative positions thereby enabling coils of various lengths to be accommodated between the fixtures, and in each of these operative positions the fixtures have an arranging and positioning action upon a coil.
  • the compacting action is mainly a function of the movement of the pressure pads which takes place after the fixtures have been brought to operative position and locked therein.
  • the arranging and compacting actions are, in a sense, independent of the length of the coil and may be closely regulated as desired.
  • the locking device preferably consists of a mandrel secured to one of the fixtures and movable relative thereto, the mandrel being projected through the center of an annular coil and an aperture in the other fixture to which the mandrel is then releaseably secured by suitable locking elements to,

  • the construction and operation of a stop of this type is more fully described in US. Patent 3,229,645.
  • the compacting and handing apparatus includes a pair of fixtures 36 and 38 which for convenience will be referred to as a compacting fixture and a banding fixture, and the fixtures are provided with wheeled bases 40 and 42 mounted for movement on a pair of rails 44 in a direction longitudinally of the axis of the coil 10.
  • FIGURE 3 the fixtures are shown in a clearance position relative to the carrier hook 13 and are moveable from this position to the operative position relative to the coil, illustrated in FIGURE 4, by suitable means such as the fluid pressure actuating cylinder 46 acting on the compacting fixture 36 and the fluid pressure actuating cylinder 48 acting on the banding fixture 38.
  • the banding fixture 38 includes a relatively thick face plate 50, a pair of parallel brace plates 51 and 52 secured and extending perpendicular to the face plate 50 on either side of the vertical centerline thereof, and a base member 54 attached to the plates 50-52.
  • a mandrel 56 is slidably mounted in a bearing 57 in the face plate 50, and is moveable from a retracted position shown in FIGURE 3 to an extended position shown in FIGURE 4 by a pair of fluid pressure cylinders 58 and 59 supported on trunnions 60 and 61 between the pair of brace plates 51 and 52, the rod of each of the cylinders being secured to a cross head 62 attached to the mandrel 56.
  • the free end 64 of the mandrel is provided with pairs of locking elements 66 arranged at spaced intervals along a portion of the length of the mandrel, inwardly from the end 64 thereof.
  • Three openings 68, 69 and 70 are cut in the face plate 50 and are arranged symmetrically about the center of the mandrel 56, as best shown in FIGURE 6.
  • a banding head 72 of conventional construction is mounted on the rear side 73 of the face plate in registry With each of the openings 6870.
  • the compacting fixture 36 is of composite construction and includes a pair of suitably interconnected front and rear plates 74 and 75 with a centrally located sleeve 76 extending between them.
  • a locking device or collar 78 provided with locking lugs 79 is rotatably mounted in the sleeve 76, the collar having an outer flange 80 with an arm 81 (FIGURE to which one end of an actuating cylinder assembly 82 is connected.
  • the other end of the actuating cylinder assembly 82 is secured to a bracket 83 carried by the rear plate 75.
  • Actuation of the cylinder assembly 82 rotates the flange 80 and collar 78 in a clockwise direction from the position shown in FIGURE 5 to place the locking projections 79 on the collar into overlapping relation with a pair of locking elements 66 of the mandrel, as shown in FIGURE 4.
  • Three pressure pad units 86, 87 and 88 are mounted on the plates 74 and 75 in a symmetrically spaced relation about the center of the sleeve 76.
  • Each of these units includes a pressure pad 90 secured to a pair of guide rods 91 slidably supported on the plates 74 and 75 and a fluid pressure cylinder assembly 92 mounted between the pressure pad 90 and the rear plate 75 so that when the cylinder is actuated, the pressure pad 90 will be moved away from the front plate 74w
