United States Patent 3,102,378 TEXTILE STRAND CONTROL DEVICE Edgar F. Walker, J12, Greenville, S.C., assignor to Adams,
Inc., Greenville, S.C., a corporation of South Carolina Filed Feb. 23, 1961, Ser. No. 92,353 7 Claims. (Cl. 57-81) This invention relates to a textile control device and particularly a device suitable for use with a textile machine in which a plurality of textile strands are supplied from a first package and then placed on a second package.
During such processes the textile strand often becomes broken with resultant loss of production and increased maintenance cost. This is particularly true in the case of a spinning or twisting frame having a drafting system in which the supply of roving is passed through a draft- Where an ends down condition occurs in such a system the roving often laps up upon the rolls of the drafting system causing damage to the rolls, aprons and auxiliary parts. Often where such a strand becomes broken and the supply continues to feed roving and the like to the drafting system, adjacent strands become damaged by becoming entangled with the excess fibers fed to the drafting system. The invention, therefore, especially involves the detecting and arresting of the supply of yarn after an end comes down or becomes otherwise faulty.
Accordingly, it is an object of this invention to arrest the feeding of roving and the like from the supply after an end comes down or becomes excessively slack.
An important object of this invention is to save Waste and especially to avoid damage to adjacent strands when an end of roving comes down or becomes defective.
Another object of the invention is to reduce maintenance cost by avoiding damage to the drafting system resulting from the continued feeding of roving from its supply.
Another object of the invention is to provide an electrically operated device which, upon sensing that a strand is defective, will break back the defective strand.

In the preferred embodiment of the invention sensing means A are illustrated in the form of variable reluctance pick up coils of the type shown in United States Letters Patent No. 2,930,180 entitled, Control System for Textile Machines in the name of Felton B. Bailey. A first scanning device B, schematically shown in FIGURE 3, has means detecting the signal produced by the variable reluctance pick up A. This signal is amplified and used by the movable member of an output or second scanner C to energize the coils -D. The coils D operate clamping mechanisms E mounted in conjunction with a clamping plate F to arrest the supply when a signal is received from corresponding sensing coils A. It will be noted that the clamping plate F forms a part of a housing carrying a plurality of such coils and that the clamping mechanisms E are provided with threading means as well as means in the form of transverse grooves for positively positioning same when in inoperative position and when clamping yarn.
Referring more especially to the drawings, FIGURES l and 2 illustrate a spinning frame 19 provided with an overhead or umbrella creel 11 from which a number of packages of roving 12 are suspended. The roving supply from the packages 12 passes over the guide rail 13 and through the clamping means E. The clamping means E are carried adjacent and project through the clamping plate F. The strands are then fed to a drafting system 14 which includes a plurality of the usual drafting rolls 15 through suitable trumpets 14a. The drafted textile strand then passes through pigtail guides 16 onto a spinning bobbin 17 to form a yarn package 18.
\ The spindles .17 are mounted in the usual bolster rail 19 Still another object of the invention is to provide an automatically operable means for arresting the yarn supply when an end comes down in a textile machine, thus avoiding the wasting of stock.
Yet another object of the invention is to provide a means to arrest the supply of a moving strand by clamping, thus causing the strand to part without the necessity of shearing same. 1
A further object of the invention is to provide a clamping means having the above advantages which is positively positioned and will not interfere with the normal passage of the strands but which, when actuated, will positively clamp same until the defect is repaired and the clamp reset.
The construction designed to carry out the invention will be hereinafter described, together with other features thereof.
The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings forming a part thereof, wherein an example of the invention is shown and where- FIGURE 1 is a perspective view illustrating a preferred embodiment of the invention in use with a spinning frame,
FIGURE 2 is a transverse sectional view taken on the line 2 2 in FIGURE 1,
FIGURE 3 is a circuit diagram schematically showing the various electrical components used in operating the preferred embodiment of the invention illustrated, and
FIGURE 4 is an enlarged perspective view illustrating a clamping device constructed in accordance with the present invention.
and driven by suitable spindle tape 24!. The ring rail 21 carries spinning rings 22 having a movable traveler 23 for distributing the yarn on the bobbin 17 to form the package 18.
The variable reluctance type pick ups A or any other suitable sensing devices for detecting faulty strands may be used. The variable reluctance pick up devices A are shown in the form of coils 24 and each is suitably fastened by means including the screw 25 to the ring rail 21. The sensing coils have permanent magnets 26, as described in the above mentioned patent, for generating a small electric current responsive to the movement of the traveler about the ring 22. The variable reluctance coils 24- are connected to a suitable cable 24a for making the necessary electrical connections.
Referring now especially to FIGURE 3, the inspection or scanning of the sensing coils is accomplished by a scanning device B which includes two sets of contacts a and b. When the rotor 27 is positioned contacting an a contact, a reset voltage is fed into the input of the amplifier section from the power supply section through a voltage divider in the form of resistors 28 and 29. This voltage is so adjusted in amplitude as to closely correspond to an actual signal from the sensing devices A and the purpose of this reset voltage will be described further below.
It will be noted that the rotor 30 of the output scanner or switch A which actuates the clamping mechanism is on an idle point for all its a positions. Corresponding and-b are thus contacted by the rotor 30 s: as
contacts a c of the mechanism C so that corresponding pick up coils A the particular spindle being scanned and, a bias voltage appears across the resistance capacitance circuit 31 in the amplifier section. This bias on the grid of the tube 32 will prevent the tube 32 from firing and therefore the relay 33 will not operate.
However, in the'case of a defective strand no signal is received by the corresponding contacts 12 from the respective sensing coilA. No signal will be fed to the amplifier and no bias will appear across the circuit 31. Therefore, the tube 32 will fire and the relay 33 will be operated. It will be noted that the relay 33 normally supplies a voltage from the power supply section to charge the condenser 34 through the resistor 35 and that the relay 33 controls the switch 3211. Thus when the relay 33- is actuated by an ends down condition it moves its contacts so that the electrical charge in the condenser 34 is discharged through the appropriate cutting coil D. A capacitor such as 34 is used hereto prevent arcing because it is completely discharged within a very short period of time and because, should a component of the amplifier circuit fail, there will be no danger of initiating improper cutter actuations.
It should be pointed out that after an end is clamped, the capacitor 34 is discharged and if the next succeeding end is down, it is impossible to cut same until the capacitor is recharged. This is the purpose of the reset points a on the input scanner B. Immediately after each scanning of a b contact, the rotor 27 is returned to an a contact. This is the final phase of the operation of the amplifier and the reset voltage returns the contacts of the relay 33 to their normal position as shown.
The clamping plate F has a pair of rearwardly extending legs 36 and 37 for holding a back plate 38 as by a pressed fit at 39 to form an elongated closed housing. The housing is positioned on a bracket 40 behind the drafting system 14. The housing formed by the clamping plate F is attached to the bracket 40 as by suitable fastening means such as the bolt and nut 41. The bracket is secured to the frame by suitable means including the bolt 42. It will be noted that the clamping coils D are suitable means including the bolt 42. It will be noted that the clamping coils D are in the form of solenoid coils 43 and that the solenoid coils are spaced within the housing and fixed to the cutting plate F by suitable means such as the mounting screws 44, A suitable cable 43a is provided for energizing the solenoid coils 43 and the electronic gear described above is housed in a suitable control box 43b mounted on the frame 10.
It will be noted that the clamping member E has a core 45 formed of magnetic material which is secured within the core 46 of the coil winding. The forwardly projecting portion or clamping member 47 is provided with a yarn or strand aperture 48 and a threading slot 49. An abutment means is provided by the first slot 50 for normally holding the clamping member or yarn guide 47 in a positive strand guiding position and a second slot 51 provides an abutment means positioned forwardly of the yarn aperture '48 to fix same when in clamping position. It
, will be noted that a recessed clamping portion in the form of a substantially v shape'd slot 52 is provided to accommodate roving which is clamped between the clamping member E. The V-shaped slot 52 serves to wedge the strand, thus facilitating breaking the strand. Room is also provided to accommodate the strand so that the clamping member E may drop down engaging the slot 51 in clamping'position.
