Definitions

  • a toothed gear which is mounted on and affixed to the shaft which turns the snubber roll.
  • This gear turns at the same rate of revolutions as does the snubber roll.
  • a sensing mechanism or signal pickup unit such as a magnetic pickup head, which, as each tooth of the gear passes by, delivers an electrical impulse to drive a scaling device or totalizing counter which furnishes one output pulse for a given number of input pulses.
  • These output pulses are, in turn, supplied to an amplifier which increases their power sufficiently to operate the desired number of counting units.
  • These counting units preferably mounted on separate winding panels of a take-up machine on which the desired package roll of filament is being wound are predetermining electrical counters and they substractively count down from their predetermined setting to zero, at which time the counter activates a switch, which supplies current to a warning signal such as an indicator lamp mounted on the winding panel. This signal or indicator lamp informs the operator that the desired length of filament has accumulated on the winding spool.
  • the counting mechanism is equipped with a switch so that it may readily be deactivated and, furthermore, the circuit is so wired that the counter is stopped and an alarm is sounded should a filament being wound on any particular spindle become broken.
  • This latter control is effectup 3,284,907 Patented Nov. 15, 1966 ice ated by mounting a switch on each winding panel so that no counts will be received by that counter unless a compensator arm is in operation, i.e., the compensator arm is being held up by filament passing around it and going to the winding spindle.
  • the compensator arm will fall to its resting position and the totalizing of subtractive counts will be stopped by that particular counter even though the totalizing subtractive counts are being received by all other counters in the assembly.
  • a switch which stops the counter it also may activate a switch which in turn activates an alarm such as a bell or signal light calling attention of the operator to the broken filament.
  • FIGURE I is a simplified schematic representation of snubber rolls and connection of the powered snubber roll to the control mechanisms of this invention
  • FIGURE II is a schematic representation of a Winder assembly with counted device and compensator arm and package being wound.
  • one fiber or filament 1 or a multiplicity of fibers or filaments la; 1b; 1c; and 1d pass (at the end of the production unit) through a set of snubber rolls 2 of which one (3) is powered and the periphery of which is, for ex- Hence, three feet of filament 1 is delivered per revolution ofthe snubber roll 3.
  • a toothed gear 5 having, for example, teeth.
  • a sensing mechanism 6 for example a magnetic pickup head which delivers an output pulse each time a tooth passes by.
  • 100 output pulses are generated by the sensing mechanism 6.
  • This counter is of a character such that it will furnish one output pulse for -any given or preset number of input pulses, which it receives from the sensing device 6.
  • the gear 5 equivalent to l0 turns of the snubber roll 3
  • the totalizing counter 7 were preset to 250, four output pulses are furnished by the counter 7.
  • the output pulses from the totalizing counter 7 are supplied to an amplifier -8 which increases their power sufficiently to operate the desired number of electrical counting units 9.
  • These counting units 9 are predetermining electrical counters, and are mounted, preferably, on separate Winder panels 10 as depicted in FIGURE Il.
  • each counting device 9 Before winding of a package of filament is started, each counting device 9 is adjusted to the same predetermined number. Such adjustment is usually performed by turning a single ⁇ set-wheel at the side of the counter.
  • the counter 9 employed such as Durant Manufacturing Company No. SY-RMF-S, is then set at 02500, for example and for each input pulse received -by the counter the number showing is reduced by one digit, e.g., after ten input pulses the number showing has become 02490.
  • the counter 9 lactuates an internal switch on the next pulse which, -in turn, actuates ⁇ a signal such as a light 11 which indicates that the requisite number of pulses has been received.
  • a switch 12 is provided on each winding panel 10 to enable disabling each counter 9 irom receiving electrical signals.
  • Another switch 13, such las la Unimax switch, is mounted on each panel so that no pulses will be received by the counter 9 of that panel unless the compensator arm 14 is in operation, i.e., being held up by filament passing laround it and ⁇ going to the winding spindle 15.
  • the compensator arm 14 Will fall to a resting position, actuating the switch 13 which disables the counter 9 even though totalizing subtractive counts are being received by all other counters in the assembly.
  • a further switch 17 which actuates an alarm or light or both to warn the operator that a filament has broken.
  • the switches 13 and 17 can be combined in -a single pole double throw switch, if desired.
  • the counter 9 actuates a signal lamp 11 which indicates to the operator that the filament package 16 contains the proper length of filament. He then turns ofi the individual counter 9 by use of switch 12, dofs the package 16, replaces a new empty core on the winding spindle 15, resets the counter 9 to the appropriate number, e.g., 02500, and turns the counter 9 back on by switch 12 so that it may once again receive pulses.

  • the predetermined counter would be set at 02500.
  • One revolution of the snubber produces one yard Iof filament, Iand one revolution furnishes 100 pulses to the totalizing counter.
