Definitions

  • the disclosure of this invention relates to a rotary strip accumulator for web-like material, such as, rolled steel strip, and includes inner and outer roller concentric baskets between which the strip is accumulated in the form of two distinct coils separated by a reversible loop of strip.
  • the baskets are formed by a series of cooperating rollers and are supported by a frame in which the rollers are cantileverly mounted on the frame so that the coils are formed externally of the frame.
  • the rollers of each basket are moved in unison by spider members supported by a common tubular member arranged coaxially with the axes of the coils.
  • 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.
  • a still further difficulty of past rotary accumulators is that the roller baskets are not maintained concentric during the entire range of movement of the baskets, and therefore require a larger machine for a given thickness and type of material.
  • 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 which basket is concentric with the inner 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, a frame for supporting the first and second baskets, and means carried by the frame for connecting the rollers to the frame in a manner that the rollers are cantileverly mounted relative to the frame and the coils are formed externally of the frame.
  • 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 2 2 of FIG. 1.
  • the accumulator illustrated includes a front and back upright members 11 and 12, supported on a common base 13 and additionally tied together by radially arranged separator members 15.
  • the front member 12 is provided with a series of equally spaced radially arranged guide slots 18 into which are received the rollers carried by bearing chocks of the inner and outer baskets 19 and 20, respectively.
  • the strip 10 is formed into two distinct coils separated by a reversible loop of strip by the roller baskets 19 and 20.
  • FIG. 2 best illustrates the construction of the bearing chocks 23 which include four pairs of cooperative antifriction bearings 24 that engage and roll over the frame member 12 while the rollers 22 are guided in the guide slots 18.
  • the outer basket 20 has rollers 27 rotatably mounted in bearing chocks 28 in cooperative pairs of twos, except for the two lowermost rollers, the chocks also being received in the guided slots 18.
  • the rollers of each basket 19 and 20 are moved radially in unison by spider members 32 and 33, the member 32 serving the outer basket 20 while themember 33 serves the inner basket 19.
  • the member 32 consists of a circular slide 34 having separate bearings 35 that allow the slide to move over a tubular support 36 which is horizontally carried by the upright members 11 and 12.
  • the slide 34 is connected to the bearing chocks 28 of the outer basket rollers 27 by links 37.
  • the links are caused to expand and collapse and, hence, causes a similar movement of the roller basket 20 on movement of the slide 34 by a tandemly arranged air-oil double piston cylinder assembly 39 which is connected to the slide by a clevis 40 connected in turn to the piston rod.
  • a tandemly arranged air-oil double piston cylinder assembly 39 which is connected to the slide by a clevis 40 connected in turn to the piston rod.
  • the air is employed to generate the power to move the piston of the cylinders and the oil is used to regulate the speed.
  • the member 33 also consists of a circular slide 41 arranged in tandem fashion with respect to the slide 34 and has spaced bearings 43 that permit the slide 41 to move over the supporting member 36.
  • the slide 41 is connected to the bearing chocks 23 of the rollers 22 of the inner basket 19 by links 44. These links are caused to expand and collapse and, hence, cause a similar movement of the roller basket 19 on movement of the slide 41 by a tandemly arranged air-oil double piston cylinder assembly 46 which is connected to the slide 41 by a link 47 similar to the assembly 39.
  • each sleeve 34 and 41 can be moved by a pair of screw jacks driven by separate electrical motors carried by the back upright member '11.
  • the two lowermost rollers 27 of the outer baskets are single rollers and are positively driven, the driving arrangement being best shown in HQ. 2 where separate electrical motor-gear units 52 are connected to the rollers 27 through flexible couplings 53.
  • the coupling illustrated is known as a Schmidt Coupling supplied by The Tool Steel Gear & Pinion Company of Cincinnati, Ohio. U.S.A. and described in its catalog 3000-6 dated 12/ l/69.
  • the strip is fed to the accumulator by a pair of driven pinion rolls 55 over the power driven rollers 27 of the outer basket and, hence, between the inner and outer baskets where it is caused to take the form of a reverse loop which loop is shown in outline form in FIG. 1.
  • the strip passes over a guide roll 56 and around a takeoff spool 58 to an exit guide roll 59 where the strip leaves the accumulator.
  • the condition of the strip illustrated in FIG. 1 depicts the beginning of the accumulation of the strip in which as the loop passes around the basket wraps are added to the inner and outer coils formed between the baskets and separated by the free loop.
  • the baskets are displaced continually by the controlled operation of the piston cylinder assemblies 39 and 46.
  • the cantilever construction of the baskets will allow the condition of the strip to be inspected continuously and'maintenance to be formed on the rollers without the removal of any parts of the frame.
  • An accumulator for weblike material having a first series of rollers arranged to form a circular inner roller basket and a second series of rollers arranged to form a circular outer roller basket,
  • said two baskets being arranged relative to each other so that a number of convolutions of material can be wound into two distinct coils separated from each other by a reversible loop of material
  • said frame includes a member arranged in a plane normal to the planes containing the axes of rotation of said rollers,
  • said member having a number of guide slots located radially to the axes of the formed coils,
  • roller supporting means received in said guide slots
  • said frame including a central supporting means for carrying said spider elements in tandem fashion and in a manner that the elements are free to move parallel to the axes of the formed coils,
  • said member of said frame arranged on one side of said frame for connecting said rollers of said first and secondbaskets to the frame in a manner that the rollers are cantileverly mounted relative to said frame and project away from said frame so that said rollers are open and unobstructed from said one side of said frame.
  • An accumulator according to claim 1 including an air-oil double piston cylinder assembly wherein air is employed to generate the power to move the piston and oil to regulate the speed of the piston and control means for controlling the operation of said piston cylinder assembly.
