Definitions

  • the present invention provides a reel where the expanding and collapsing is accomplished by one or more rapidly replaceable wedge insert assemblies arranged between the arbor and segment.
  • the wedge assemblies with two cooperative wedge elements, one element being associated with the outer segment of the reel and the other element with the central arbor thereof, in which bores are provided to receive the elements in a manner that the elements can be readily installed and removed and wherein the number of assemblies can be varied depending on the loads to which the reel is to be subject.
  • Another object of the invention is to provide for the wedge assemblies to include a wedge element made up with an inclined slot and a second wedge or piston element having a sliding pin or T-shaped member which is received in the slot.
  • FIG. 1 is an end elevational view, with certain portions in section, of a three segment reel built in accordance with the teaching of the present invention, two segments being shown in their expanded positions and the third in its collapsed position;
  • FIG. 2 is a sectional view taken on lines 22 of FIG. 1 where according to FIG. 1 the upper segment is shown collapsed and the lower segment expanded;
  • FIG. 3 is an outside view taken on lines 3-3 of FIG. 2 with the piston insert element removed;
  • FIG. 4 is an outside view taken on lines 44 of FIG. 2 with the wedge insert element removed;
  • FIG. 5 is an exploded perspective view of the outer wedge and piston elementsshown in FIG. 2;
  • FIG. 6 is an exploded perspective view of a second embodiment of the wedge-and piston elements shown in FIGS. 1 5;
  • FIG. 7 is an exploded perspective view of a third embodiment of the wedge and piston elements shown in FIGS. 1-5.
  • FIGS. 1 and 2 there is shown an expandable reel for winding or unwinding flat rolled steel strip having three outer and radially displaceable segments 10, 12 and 14 arranged equi-distantly around a center supporting arbor 16, which as shown in FIG. 2 is cantileverly mounted and rotatably supported by a bearing assembly 18. As indicated by the arrow 19 in FIG. 2 the arbor is displaceable axially to effect the expansion and collapsing of the segments.
  • the power means for accomplishing this axial displacement is not shown nor are other well-known components of the reel assembly such as the drive.
  • the inner or drive ends of the segments 10, I2 and 14 have circular projections 20 that arereceived in a rotating C-shaped head 22, the clearance relationship being such that the segments are permitted to move radially but restricted from moving axially and at the same time through a T-slot construction the segments are driven by the head 22.
  • the other end of the segments 10, 12, and 14 are similarily restrained and driven by a circular end cup 24 which is secured to and rotates with the adjacent end of the arbor 16.
  • a closer inspection of the upper and lower end portion of the reel shown in FIG. 2 will reveal the relationship between the members 22 and 24 and the segments in both the expanded position of the reel which is illustrated by the segment 14 and the collapsed position which is illustrated by the segment 12, the expanded and collapsed positions also, as noted before, being revealed in FIG. 1.
  • it may be highly desirable to provide for a positive restrain at the longitudinal center of the segments which could be accomplished by employing one of the two disclosed forms of the interconnected types of wedge assemblies.
  • FIG. 2 two different types of wedge assemblies are employed, the inner ones being of a more simpler and less costly construction than the outer ones.
  • the particular use of the two different types of wedge assemblies may change depending on the application of the reel, and as already noted the different type wedge assemblies are interchangeable so that if one or moretparticular features of one type are desired, the desired type can be substituted for the one presently being employed.
  • wedge assemblies 28 and 30 located at the opposite ends of the arbor and segments, these are provided because they have safety pins for preventing the segments from inadvertently separating themselves from the arbor due to centrifugal force should the reel, if used as a wind-up reel, be rotated at high speeds without any strip being would around the reel. In certain reel applications it may be desirable to decrease or increase the number of these pin wedge assemblies depending on the speed of the reel and other factors.
  • each of these elements is provided with a number of identical bores.
  • the arbor 16 it is provided with three axial rows of'sp'aced apart bores 32 which can be seen clearly from FIG. 4.
  • bores receive tubular liners 34 each having opposed pair of inward projections 36.
  • These projections 36 form a type of a bayonet connection with an inward part of wedge elements 38 which, as best shown in FIG. 5, have circular projections 40 which when assembled in the liners are rotated under the projections 36 of the liners 34.
  • each outward portion is machined with a wedge portion 44 having an inclined surface 45 and an inclined +-shaped slot 46, again as best shown in FIG. 5, the length and degree of the inclined surfaces being designed to give the necessary expansion and collapsing of the segments 10, 12, and 14.
  • the liners 34 are secured to the arbor 16 by two bolts 48.
  • each wedge element 38 Cooperating with each wedge element 38 is a piston element 50 having an inclined surface 51 that engages the inclined surface 45 of the element 38.
  • the piston elements are received in bores 52 formed in the segments 10, I2, and 14 directly across from the bores 32 of the arbor 16.
  • the bores 52 receive liners 54, best shown in FIG. 3, which are provided with projections 56.
  • the piston elements 50 likewise have projections 58 to form a bayonet connection with the projections 56.
  • the piston elements have cut-outs 59 that allow the elements to be inserted into the liners 54 then rotated to bring the projections 58 under the projections 56 of the liners 54.
  • the liners 54 are secured to the segments by bolts 60 and further by slideable keys 62 received in cut-outs 64 best shown in FIG. 3.
  • a lug 66 from which opposite sides project pins 68 that pass into the +-shaped slot 46 of the wedge elements 38 and which are guided by and slide on the inclined surfaces of the slots wedge ofthe elements.
  • the expansion and collapsing of the segments 10, 12, and 14 are accomplished by the axial movement of the arbor 16 which carries with it the wedge elements 38.
  • the segments are cut-out at 70 which cut-outs are best shown in FIGS. 2 and 3.
  • the three assemblies 72 76 each have wedge elements 38 and piston elements 50 that are received in the bores 32 and 52, respectively.
  • the assemblies 72 76 have cooperative inclined surfaces 82 and 84.
  • a slot 86 provided in each of the wedge elements 44 allows the segment to extend into these slots when in the collapsed condition, as shown in FIG. 1.
  • FIG. 7 shows the third embodiment of the wedge assemblies of the present invention in which in place of the +-shaped slot 46 and pins 68 of the assemblies 28 and 30, the'positive interlocking and driving arrangement is accomplished by providing a simplified construction of a short T-slot 88 and mating T 90.
