Definitions

  • the accumulator device In such machines, termed accumulatorstranding machines, the accumulator device consists of an elongated cage or frame which rotates about an axis parallel to its longest edge.
  • the device has sets of wheels, each consisting of one or more wheels closely spaced, which are located at the opposite ends thereof.
  • Each set of wheels rotate freely about an axis and their planes of rotation lie in a plane containing the axis of rotation of the frame.
  • a nipple serving as a stranding point to which the strand elements are fed. After stranding, they enter the accumulator device and are fed, as by a set of pulleys, alternately on a wheel of the first set, then over a wheel of the second set, then again over a wheel of the first set, etc., until they pass from the last wheel of the second set to means located immediately adjacent the accumulator device for protecting the stranded elements from kinking at the point where the direction of lay changes.
  • Such means can take the form of a belt spinner.
  • the instant invention is directed to an accumulator stranding machine having a rotating accumulator device whose direction of rotation can be reversed after a given number of revolutions. Accordingly, there is provided a counter for each direction of rotation. One counter activates a reversal of the drive and also engages the other counter for the other direction of rotation, after a. preset number of revolutions.
  • One counter activates a reversal of the drive and also engages the other counter for the other direction of rotation, after a. preset number of revolutions.
  • separate coupling means is provided for each direction of rotation. Further improvement is achieved by activating the couplings electrically and switching in simultaneously the counter for the corresponding direction of rotation; disconnecting after a given number of revolutions the corresponding coupling and switching in the coupling for the opposite direction of rotation.
  • the couplings can take the form of electrodisc or magnetic powder clutch devices.
  • the reversal of the electric motor drive is accomplished by reversing the polarity of the motor. Simultaneously with such polarity reversal, the counter corresponding to the new direction of rotation is switched in. After a given number of revolutions, this counter is effective to change the polarity to the opposite direction of rotation. In this case, no couplings are required. However, braking of the armature of the motor is required to make possible the reversing action of the motor.
  • Pulse counters are used in the instant invention, with particular advantage. Such counters receive their inputs from a pulse source that is dependent on the speed of rotation; and whose polarity depends on the direction of rotation. Rectifier means is connected between the pulse source and each counting device so that the direction of transmission of the two rectifiers is opposite. After a given number of revolutions, the counter activates either a coupling for the opposite direction of rotation or the polarity reversal of the drive motor. Selected preselector counters are used in the system.
  • FIG. 1 is a schematic showing of one embodiment of the invention
  • FIG. 2 is a schematic showing of another embodiment of the invention.
  • FIG. 3 is a schematic showing of still another form of the invention.
  • the accumulator stranding system generally indicated at 10, comprises a motor drive 11 for operating the accumulator stranding machine 12.
  • the drive 11 acts through a transmission 13 on a coupling means 14 having one direction of rotation, and a coupling means 14A having the opposite direction of rotation; thus permitting machine 12 to be driven in either direction.
  • Each of the couplings 14, 14A has associated therewith a counter, as at 15, 15A.
  • the connections between the couplings 14, 14A and counters 15, 15A is such that the coupling is under control of its associated counter and after a given number of revolutions, preset in the counters, the associated coupling is inactivated and automatically, the other counter is activated to control its associated coupling.
  • the system A is similar to the system 10 shown in FIG. 1, except that counters 17, 17A are pulse operated from a pulse source 18 which is operated from drive element 19.
  • Source 18 delivers pulses at a frequency depending on the rotational speed and with a polarity in accordance with the direction of rotation.
  • Unidirectional rectifiers 20, 20A in circuit with source 18 and counters 17, 17A provide for automatic connection and disconnection of the couplings 16, 16A after a given number of revolutions preset on the counters.
  • a motor 11A drives the machine 12 directly.
  • a pulse generator 18 is driven by motor 11A and pulses counters 17, 17A selectively through the unidirectional rectifiers 20, 20A, as set forth above.
  • the counters 17, 17A operates suitable means 21 such as solenoids or the like, to in turn operate a reversing switch 22 in circuit with motor 11A and current source 23.
  • suitable means 21 such as solenoids or the like, to in turn operate a reversing switch 22 in circuit with motor 11A and current source 23.
  • the polarity condition of motor 11A is under control of the preset counters 17, 17A to reverse the rotation of machine 12 at the appropriate time.
  • couplings 16, 16A are electrically operable and may be of either the electromagnetic disc or powdered metal types, well known in the art.
  • the connections between the counter means and the couplings which allows for automatic connection and disconnection of the counters so as to allow for operation of but one counter and associated coupling at any given time, are well known in the art.
  • each counter device being operative to activate the other counter device at the end of said predetermined number of revolutions.
  • said rotating means comprises a pair of coupling means respectively rotatable in opposite directions.
