Definitions

  • This invention relates to an improved control system for a textile machine, having a plurality of strand controlling devices, which utilizes electrical sensing means positioned adjacent each strand sensing slack or broken strands by establishing a differential in output when such condition occurs.
  • An important object of this invention is the provision of an improved ends down and slack ends indicator in which a magnetic coil pick-up and the like is positioned closely adjacent the traveler so as to establish a voltage during normal operation of the machine and in which sensing means is actuated by the lessening or absence of such voltage when the traveler slows down or stops resulting from a slack end or a broken end.
  • Another important object of the invention is to provide an improved control system for a textile machine in which electrical sensing means are positioned adjacent each strand and in which scanning means are provided to monitor individual strands.
  • Another object of this invention is to provide a sensing device for indicating ends down and slack ends which operates at an exceedingly low voltage established by the action of the traveler and a sensing circuit capable of positively and effectively utilizing such small voltage for actuating a variety of indicating means.
  • Still another object of the invention is the provision of atent o an ends down indicator which may be easily installed on textile machines of standard types without modification of the machines and which will be economical and yet give a variety of information concerning the operation of the machine.
  • Figure 1 is a schematic transverse sectional view of a ring frame and the like showing an embodiment of the present invention in use therewith,
  • FIG. 2 is an enlarged perspective view of the ring and sensing device shown in Figure 1,
  • Figure 3 is a schematic view showing the electrical connections for the sensing devices including a sectional plan view of one of such devices, and
  • Figure 4 is a schematic diagram showing a circuit constructed in accordance with an embodiment of the present invention.
  • An amplifier D includes two high gain vacuum tubes and a rectifier tube for placing the amplified voltage established by the magnetic coil pick-up upon the control grid of the relay tube E which serves as a sensitive switch controlling the operation of the relay circuit F.
  • the relay tube is shown to be of the gas filled type, but may be of any other suitable type which will function as a switch, so that when the voltage on the control grid reaches a predetermined value the tube will fire and maintain a maximum output almost instantaneously.
  • the tube E shown in the drawing is rated 'to fire when the voltage on the control grid drops below a predetermined value so that the relay mechanism may be actuated thereby.
  • a magnetic coil pick-up is best shown in Figures 2 and 3 to include a permanent magnetic core 16 and a coil 17 surrounding the magnetic core 16.
  • the magnetic core 16 establishes astable magnetic field around the core and the coil 17. Since the variable reluctance pick-up mechanism is positioned closely adjacent the traveler in its normal movement during normal operation of the machine the traveler will pass through the flux lines established by the magnetic core. The magnetic field will become alternately distorted and then return to its original shape.
  • the magnet 16 is carried within the core of a spool 16a and that the coil 17 of insulated wire is wound upon the spool.
  • the coil is preferably covered with insulating material 17a.
  • a suitable fastening in the form of a strap 17b secures the sensing device A to the ring rail 15 by screws 170.
  • a terminal strip 17d is secured to the device A by a screw 16b which is threaded into the core of the spool 16a.
  • One of the ends of the coil 17 is grounded to a common ground G in the form of shielding which surrounds the insulated leads 18 from the other end of the coil.
  • the leads 18 are each connected to one of the spaced contact points 19 of the scanning mechanism C.
  • the ground G and the insulated leads 18 carried thereby are supported by the rail 15 by suitable fastenings 15a.
  • the scanning mechanism C is shown schematically in Figure 4 as including a plurality of spaced contact points 19 each of the contact points being connected respectively to one of the coils 17 of the variable reluctance pick-up mechanism A as described above. As has previously been pointed out a variable reluctance pick-up mechanism A is positioned closely adjacent each of the rings 14. The scanning mechanism is for the purpose of sensing the voltage on each of the contact points 19 to ultimately determine whether or not that end of yarn is being wound properly on its respective bobbin 13.
  • the rotor 25 of the artificial injection voltage system is operated also off of the shaft 21, this rotor 25 is synchronized with the rotor 20.
  • the rotor 25 is so constructed and the points 23 and 24 are so spaced, as shown in dotted lines in Figure 4, that should two adjacent ends come down at the same time the relay mechanism described below will be reset due to a voltage received from this artificial injection system.
  • the voltage which is applied to the inner ring comes from the power supply section which will be described below through a resistor 26 which has a high rating so that the voltage will be comparable to that received from the magnetic coil pickups A and the contacts 19.
  • the relay coil 33 operates double relay switches 34 and 35.
  • the relay contact 34 operats the coil 36 of a counting mechanism to count ends down time while the relay contact 35 closes a locking relay 37 for closing contacts 39 to close the circuit across a signal lamp 38.
  • a reset switch mechanism 40 is used to open or unlock the latching mechanism actuated by the coil 37 by energizing coil 41 and open the relay contacts 39 thus de e'nergizing the
  • the power supply for the amplifier andrelay sections is shown in the upper portionof Figure 2 and the primary coil 42 of a transformer is' shown in inductive relation to a low voltage secondary coil 43 and a high voltage secondary coil 44.
  • the low voltage secondary coil 43 is connected in such a manner as to supply electrical energy to the heaters of the tubes.
  • the thyratron E must be extinguished by placing a changing voltage on the plate so that the grid thereof may regain control following actuation of the relays preparatory to further operation.
  • the resistance and capacitance of the voltage divider 47 may be so chosen as to provide a frequency or time constant such as will extinguish the tube E and this in efiect makes a relaxation oscillator of the tube. This frequency is sufficiently high that the relay will not be triggered thereby.
  • the improvement including, means positioned closely adjacent the traveler establishing electrical energy resulting from movement of the traveler, and a sensing circuit connected across such means giving a signal and the like upon a predetermined drop in the magnitude or" said electrical energy, whereby upon breakage or excessive slackness of the strand a reduction in the speed of the traveler will result in actuation of the sensing circuit upon such a predetermined drop in electrical energy.
  • a control system for a textile machine having a traveler which is moved in a circular path by the strand being wound thereby during normal operation of the machine including, electrical sensing means positioned adjacent each strand sensing slack or broken strands by establishing a dilferential in output of electrical energy responsive to traveler action when said strand breaks or becomes excessively slack, a scanning device successively detecting such differentials in output, means indicating slack or broken strands, switch means actuating the means indicating slack or broken strands, means amplifying the electrical energy detected by said scanning device actuating the switch means controlling the means indicating slack or broken ends.
