  • Another difficulty of past rotary strip accumulators is the extreme difficulty in performing ordinary maintenance and being able to easily and quickly determine the condition of the strip and roller baskets during operation.
  • the object of the present invention to provide an improved construction of a rotary strip accumulator of the above-noted type which will overcome each and every one of the aforesaid disadvantages noted with respect to present-day rotary accumulators.
  • the present invention provides a strip accumulator having a first series of rollers arranged to form an inner roller basket, a second series of rollers arranged to form an outer roller basket, the baskets being arranged relative to each other so that a number of convolutions of strip can be wound into two distinct coils separated by a reversible loop of the strip, means for supporting said series of rollers in cooperative pairs, and separate means for adjusting at least some of said cooperative pairs of rollers.
  • Another object of the present invention is to provide an accumulator in accordance with aforesaid objects having a frame portion arranged normal to the axes of the distinct coils being formed in the accumulator, which portion is substantially open to the exterior of the frame thereby exposing the baskets of the accumulator.
  • FIG. 1 is an elevational view, certain portions being omitted for clarity, of an accumulator incorporating the features of the present invention
  • FIG. 2 is a sectional view taken on lines 22 of FIG.
  • FIG. 1 there is illustrated an accumulator for rolled steel strip, the entry and delivery of which is indicated by the arrows associated with the strip 10, in which it is desired to feed the strip, made up of a continuous supply of coils, to a processing apparatus not shown, such as, a pickling line, where the line is to be operated continuously even though succeeding coils must be welded end-to-end which requires a stoppage of the strip in the welding zone.
  • a processing apparatus not shown, such as, a pickling line, where the line is to be operated continuously even though succeeding coils must be welded end-to-end which requires a stoppage of the strip in the welding zone.
  • the accumulator illustrated includes a pair of spaced-apart upright frames 11 and 12 supported on common base members 13 and additionally tied together by separator beams 15. Both the outside and in side frames, with respect to the driving side of the accumulator, have large open areas 18 between their interiors and a centrally located inner tubular member 19.
  • the strip- 10 is formed into two distinct coils separated by a reversible loop of strip by inner and outer cooperative roller baskets 22 and 23, respectively.
  • One of the features of the present invention is to greatly simplify the construction and adjusting arrangement of these rollers, accordingly in referring first to the inner basket 22, it is made up of eight cooperative pairs of freely rotatable rollers 24, the pairs of rollers being carried at their opposite ends by carriage members 25. Each carriage member is guided radially relative to the center of the accumulator by a pair of guiding rods 26 which are best illustrated in FIG. 2 where the inner ends of the rods are shown connected to the tubular member 19 and their outer ends to one of the beam members 15. As also shown in FIG.
  • the carriage members 25 are allowed to move relative to the rods 26 in a radial direction by virtue of bushings 29 and are carried by parallel sided arms 31 of a tri-sided support member 32 which encloses the rods 26 and the rollers 24.
  • Each support member 32 is adjusted radially to thereby similarly adjust the rollers 24 by a screw jack 34 connected to a motor 35, both of which are carried by one of the stationary beam members 15.
  • the supporting arrangement for the outer basket 23 is somewhat different in construction than that of the inner basket and is best shown in FIG. 2.
  • the outer basket is made up of eight cooperative pairs of rollers 38 rotatably supported at their opposite ends by carriage members 39, in which the adjacent pairs of inner and outer rollers with their guiding members are alternately arranged about the circular path of the strip.
  • the rollers of the lower two pairs of rollers 38 are driven positively by being directly connected to individual motors 41 while the other rollers of the outer basket are freely rotatably mounted in the carriage members 39.
  • Each carriage member 39 is slidably received and radially guided by a pair of guide rods 42, the two elements being separated by bushings 43.
  • the innermost ends of the rods are secured to one of the stationary beam members 15, which as noted before, are carried by the frames 11 and 12.
  • the members 15 also carry a screw jack 45-for each pair of rollers and its driving motor 46, the jack being connected to its associated roller set 38 by a rod 47 for imparting movement to the roller set in a radial direction.
  • FIG. 2 the generally rectangular outline in phantom is meant to depict the outline form of the spiral discharge spool that supports and guides the strip leaving the accumulator.
  • the strip 10 is fed to the accumulator and as the reversible loop rotates in a counterclockwise direction under the influence of its own feeding force and the rotation of the rollers 38 of the two lower pairs of rollers, convolutions of strip are built up to form an inner and outer coil, during which time the baskets 22 and 23 are adjusted radially by the screw jacks 34 and 45, respectively, until the storage capacity of the accumulator is reached.
  • the strip may be fed from the accumulator, the present invention allows such movement of the baskets and their operating condition, as well as the condition of the strip, to be readily observed.
  • said two baskets being arranged relative to each other so that a number of convolutions of the material can be wound into two distinct coils separated from each other by a reversible loop of said material, and said rollers of each basket being arranged in cooperative pairs,
  • said guiding means having opposed ends
  • each cooperative pair of rollers of one of said baskets and its associated guiding means are arranged circumferentially relative to the axes of said formed coils between two cooperative pairs of rollers of the other basket and their associated guiding means
  • screw jack means for independently adjusting, at
  • a frame having a member arranged outside of the ends of said formed coils and in a plane normal to the axes of said formed coils having an opening concentric with the axes of said formed coils sufficient to expose to the outside of said frame said inner and outer baskets in at least one of their operating positions,
  • said frame including an inner circular support member for supporting similar ends of said guiding means
  • said guide means of each of the rollers of said inner roller basket includes a pair of parallel guiding rods
  • said two baskets being arranged relative to each other so that a number of convolutions of the material can be wound into two distinct coils separated from each other by a reversible loop of said material, and said rollers of each basket being arranged in cooperative pairs,
  • said guiding means having opposed ends
  • each cooperative pair of rollers of one of said baskets and its associated guiding means are arranged circumferentially relative to the axes of said formed coils between two cooperative pairs of rollers of the other basket and their associated guiding means
  • screw jack means for independently adjusting, at
  • a frame having a member arranged outside of the ends of said formed coils and in a plane normal to the axes of said formed coils having an opening concentric with the axes of said formed coils sufficient to expose to the outside of said frame said inner and outer baskets in at least one of their operating positions,
