Definitions

  • the cores of the yarn supplying coils when depleted, are often dotted and ejected although the yarn is not fully removed therefrom so that smaller or larger quantities of It is then necessary to sort the cores with such yarn remainders from those bare of yarn.
  • sorting has been done with the aid of devices in which the doffed cores pass on a conveyor belt along a feeler located above the travelling cores. If a core contains a residual winding of yarn, the feeler is mechanically lifted and closes an electrical contact. This actuates a magnet which control an ejector to throw the core off the conveyor into a collecting box.
  • an ejector such as a mechanical ejecting device or a blowing current of air.
  • it may happen that parts of the yarn or fibers will adhere to the feeler lever thus gradually soiling or clogging the feeler lever or causing the core to remain stuck at the feeler lever.
  • the surface of the feeler lever a curved shape, at least at the front end which may become hooked into residual amounts of yarn on a core, the middle portion of the feeler being curved away from the front and the rear end at the feeler side facing the core, so that during travel of the core over the feeler, the front or hook portion of the feeler will always point toward the core. Consequently, when during such travel of the core the rear of the feeler lever touches the core, a reliable engagement of the forward, hook-like front of the feeler with the core is always secured.
  • the forward end, or also the rear end, of the feeler an arcuate shape approximately adapted to the circumference of the core, so that the feeler lever has substantially a peripheral line engagement or area engagement with the core. It has been found that a particularly reliable hooking of the feeler lever into any turns of yarn is obtained if the front end of the feeler lever is provided with teeth, particularly with a number of needle-shaped tips.
  • the feeler lever may be mounted on a stationary pivot so that when the feeler turns about the pivot, it will lift the core which is then lowered by the feeler asthe latter returns to its starting position.
  • the rotary movement of the feeler lever may then serve to actuate a switch which causes mechanical or pneumatic ejection of the sorted cores with yarn remainders, whether many or only few residual turns of yarn are located on a core and regardless of the location of such turns, even if they are situated in grooves of the core.
  • an apparatus for sorting coil cores with yarn remainders from those free of remainders is provided with selector means for issuing the respective cores to different locations, and with a checking device responsive to the presence of a yarn remainder on a core, this checking device being in controlling connection with the selector means.
  • the checking device comprises a feeler which has a hooklike front engageable with the cores to be sorted so as to hook behind any residual turns of yarn on the core.
  • the feeler is preferably designed as a lever which is pivotally mounted so that, while a relative displacement in the axial direction of the core is imparted between core and feeler, the feeler will first hook into any turns of yarn and will then rotate about its pivot point, this angular displacement being utilized for controlling the above-mentioned selector means in the manner described.
  • the cores to be sorted may be moved past the feeler with the air of a pusher.
  • the pivoted feeler lever according to another feature of my invention, may be given such a design that the turning movement of the feeler ing movement of the supporting lever.
  • the pivot point of the feeler lever a displaceable mounting. It is particularly advantageous if the pivot point of the feeler lever is yieldable under the weight of the core in opposition to a force storing means, for example a spring. According to a further feature of my invention, therefore, the pivot point of the feeler lever is located on a supporting lever biased by a spring which tends to move the feeler pivot toward the locality of the core, the force of this spring being lower than the weight of the respective cores to be sorted.
  • This yielding movement of the supporting lever may act upon a switch to effect the selective ejection of the core in the abovedescribed manner, for example by controlling a current of air or a mechanical ejector such as a mechanical switch as constituted by a pivotally mounted trough or the like.
  • the feeler lever is made self-cleaning. This is done by having its back extend substantially parallel to the generatrix lines of the core when the feeler has completely pivoted to unhooking position. Any fibers or yarn residues as may adhere in the teeth or needle points of the feeler are then removed by friction with the residual turns of yarn on the core.
  • FIG. 2 is a schematic sectional view along the line IIII in FIG. 1.
  • FIG. 3 is a circuit diagram of the apparatus shown in FIGS. 1 and 2.
  • FIGS. 4 to 7 illustrate in section the checking device of the apparatus in four respectively different stages of operation
  • FIG. 8 shows part of the checking device in section, seen from the right of FIG. 6.
  • the tubular cores of yarn supply coils, such as spinning cops, dotted from a winding machine are transferred, for example by means of a conveyor, into a magazine box 1 (FIG. 1), if desired, after eliminating those cores that still contain a body of yarn sufficient for re-insertion of these cops into the winding machine.
  • the core 2 is shown to carry a residual winding of yarn.
  • the cop 3 is completely bare.
  • the core 4 carries only a few residual turns of yarn which during the last stage of the unwinding operation were pulled toward the tip of the cop.
  • the lowermost core 2 lies in front of a pusher rod 5 which reciprocates horizontally.
  • the rod 5 is driven by an arm 8 connected by a linking rod 7 with an eccentric pivot on a disc 6 on the shaft of a drive motor 6. Whenever the pusher rod 5 moves from the illustrated position to the right, it shifts the lowermost cop from the magazine 1 through a checking device 9 onto a support in a selector device 10.
  • This device comprises a feeler lever 11 whose front, directed against the travel direction of the core 2, is provided with a number of teeth or needle points 12 (FIG. 8).
  • the top surface of the feeler 11 as shown in FIG. 4 is ground to a slightly hollow, concave shape so that the teeth or needle tips are directed toward the core 2 and beneath any residual amount of yarn as may still be wound upon the core.
  • this rear end urges the teeth or tips at the feeler front against the core body.
  • the feeler lever 11 is rotatable about a pivot pin 13 and is urged to the illustrated position (FIGS. 4, 5) by a spring 14 seated upon the pivot pin 13.
  • the pivot pin 13 is mounted on a supporting lever 15 which is rotatable about a fixed pivot pin 16.
  • Another spring 17, seated on pin 16 biases the lever 15 into engagement with a fixed stop '18.
  • the lever 15 has an extension 19 beneath which the push button 20 of a switch 21 is located.
  • the switch 21' is actuated when the supporting lever 15 rotates clockwise about its pivot axis in opposition to the force of the spring 17.
  • the above-described levers 11, 1S and their pivots and springs are protected by a housing 22.
  • the feeler lever now hooked to the yarn, turns clockwise about its pivot as shown in FIG. 6.
  • the torque imposed by the biasing spring .17 upon the supporting lever 15 is lower than the torque acting upon the lever 15, so that the lever 15 also turns clockwise and its extension 19 depresses the push button 20 of the switch 21.
  • the feeler lever reaches the ultimate, reversed position shown in FIG. 7.
  • the rear side 11' of the feeler lever 11 is so designed that in this reverse position the side 11' is approximately parallel to the adjacent generatrix line of the core 2.
  • the feeler lever 11 After the core 2 has passed fully beyond the checking device 9, the feeler lever 11 returns to the position shown in FIGS. 1 and 4, due to the action of the springs 14 and 17. It will be recognized that if a completely empty core 3 passes through the checking device 9, the feeler lever 11 cannot hook into any obstacle and for that reason cannot turn clockwise. Consequently, the supporting lever 15 remains in its position of rest determined by the engagement with the stop 18 (FIGS. 4, 5) so that the switch 21 is not actuated.
  • the relay 27 has a normally open self-holding contact 29 in addition to the above-mentioned selector contact 39. Consequently, when switch 21 energizes the relay 27, this relay seals itself in at contact 29 and simultaneously switches the selector contact 36 from fixed contact 31 to contact 32, thus connecting the switch 23 with a second magnet 34 of the selector device ltl.
  • the lever 8 again actuates the wiper switch 23 and thus closes the circuit between currentsupply leads 24 and 25 through contacts 30, 32 and magnet 34. Now the magnet 34 of the selector device 10 is energized.
  • the magnet 26 is energized when the checking device 9 detects absence of yarn on a core. connected with the armature 26 of magnet 26 then rotates a lever 37 on a pivot shaft 36 to which a supporting sheet member 33 of sheet metal is fastened. When the magnet 26 is energized, the supporting sheet 38 is thus' rotated clockwise. As a result, the core, denoted by H in FIGS. 1 and 2, previously displaced by the pusher 5 into the selector device 10, can now glide along an inclined guiding sheet 39 into a collecting box 40.
  • the magnet 34 actuates its armature 34' and causes the attached lever 41 to rotate a lever 42 on a pivot shaft 43 to which a supporting sheet member 44 is fastened.
  • the supporting member 44 then rotates counterclockwise so that a core
