Definitions

  • Spinning cops have been provided with a reserve winding or tip bunch at the core tip of the cop or at the foot of the core or at both in order to facilitate the winding operation.
  • These reserve windings can be unwound at the core winding machine so as to permit a yarn end of the cop to be seized without difficulty. Since the unwinding of a reserve winding located at the core foot of the coil would mean a rather considerable expenditure of work for the usual winding station of a yarn winding machine, the spinning machines are equipped to provide a reserve winding at the tip of the coil core at the end of the spinning process.
  • This over-all cost reduction for the winding machine is brought about by the fact that the devices at each individual winding station for seizing and readying the yarn end for the unwinding operation are extremely simplified. Consequently, only a single expensive device is necessary for a large number of winding stations while relatively simple devices are employed at the individual winding stations.
  • we provide a method of readying the unwinding operation of a supply coil, such as a spinning cop by first removing the final turns of the yarn on the coil and inserting the yarn end into the hollow core of the coil. Thereafter the coil is automatically fed to the winding stations of a coil winding machine and the yarn end is removed at that station by vacuum from the bore of the coil core and readied for the knotting device.
  • a supply coil such as a spinning cop
  • a supply coil readying machine for carrying out the method of our invention for several or all of the winding stations of one or more winding machines.
  • the supply coil readying machine is provided with means for removing the final yarn turns on the coil and inserting the yarn end into the bore of the coil core, and with suction means located at the winding stations for seizing the yarn lying within the bore of the coil cores.
  • FIG. 1 is a front elevational view of a multi-station winding machine provided on its front side with a supply coil readying apparatus according to the invention.
  • FIG. 2 is a side elevational view of a single winding station and of the supply-coil yarn readying apparatus.
  • FIG. 3 is an enlarged elevational view partly in section showing a detail of the readying device of FIG. 1 as viewed from the rear.
  • FIGS. 4 to 7 are elevational views partly in section of part of the readying device shown in FIGS. 1 and 2 in difierent stages of operation.
  • FIG. 1 there is shown a multi-stationwinding machine having a pedestal support 1 which carries an inclined table 2 upon which magazine containers 3 and 4 for dispensing a number of spinning cops K contained therein are located.
  • the containers are subdivided into a number of vertically extending chambers, and the cops are piled up vertically in each chamber side to side.
  • the upper portion of the inclined table is provided with the chute 5 through which the cops are guided successively from an opening in the bottom of the magazine chamber 4 onto a readying plate 60 from which they can drop into the readying device designated by the reference numeral 6 as a whole in FIG. 1 and hereinafter described more fully with reference to FIGS. 4 to 7.
  • the readying device 6 a yarn end is first unwound from the cop delivered to the readying device 6 and is then inserted in the hollow core of the cop as is explained hereinafter with regard to FIGS. 4 to 7.
  • the readied cop proceeds onto an endless chain conveyor 7 provided with inclined holding troughs 37 (FIG. 2) for receiving the ready cops.
  • the conveyor 7 passes along the individual winding stations to supply them with cops in accordance with the need and is entrained at one end about a shaft 38 carried by the pedestal 1.
  • the readying device 6 is controlled by a feeler 9, which is switched on or off for example.
  • the feeler 9 inspects the passing trough 37 of the chain conveyor 7 for the presence or absence of a cop at a location just beneath the readying station.
  • the feeler 9 rotates in a counterclockwise direction about a pivot supported on the pedestal 1, thereby releasing the drive mechanism of the readying station.
  • a tappet 10 is then swung against the next cop that is to be readied which is located on the supporting surface 60, moving this cop into the position in which it is located on a roller pair 61, 62, hereinafter described in greater detail with regard to FIG. 3, displacing the previously readied cop located on the roller pair which drops into a chute 10a leading to the unoccupied trough 37 of the chain conveyor 7. If the conveyor trough 37 is occupied, the feeler 9 is prevented by the cop in the trough from turning counterclockwise as shown in FIG. 1 and the readying station accordingly remains inactive.
  • each of the individual winding stations is mounted on a machine frame 11 and comprises a pivotable holder 12 rotatably supporting a take-up spool 13.
  • the yarn Y being unwound from the supply coil K passes through a tensioner 18, thence over a guiding drum 14 onto the take-up spool 13.
  • the take-up spool 13 is frictionally entrained by the drum 14 to rotate at a constant peripheral speed while the yarn Y passing through a guiding groove of the drum 14 as shown in FIG. 1 is wound on the take-up spool so as to form a cross-wound yarn package.
  • Two yarn seeking members 15 and 16 seek and seize the respective yarn ends of the take-up spool and of the supply coil in the event of yarn breakage or depletion of the preceding supply coil and deliver the two ends to a knotter 17 which ties them to gether.
  • the yarn seeking member 15 is in the form of a suction tube pivoted on the frame 11 and has a nozzle opening which extends along the take-up spool 13.
  • a non-illustrated yarn feeler which normally engages the yarn Y deflects causing the guiding drum 14 and the takeup spool 13 to be stopped or to be rotated only slightly in the opposite rotary direction in order to slightly unwind the spool 13.
  • the suction member 15 is connected to a non-illustrated source of suction and seizes the yarn end of the take-up spool 13. Thereafter, the suction member 15 pivots in a clockwise direction shown by the arrow along the circular dot and dash are associated therewith so that the one end from the take-up spool 13 is placed up against the knotting device 17.
  • the yarn seeking member 16 similarly of suction-tube construction is pivoted on the machine frame 11 from a position in which it seizes the yarn end coming from the cop K, that is mounted on the mandrel 19, when a yarn break occurs or a newly replaced supply coil has been substituted for a depleted coil, and then swings along the associated dot and dash arc in the counterclockwise direction of the arrow so that the yarn end from the supply coil intersects with the yarn end from the take-up coil at the knotting device 17 which thereafter ties both yarn ends together before the winding of the take-up spool is resumed.
  • the mandrel 19 which supports a supply coil is pivotably mounted so that it can be moved from the illustrated solid-line position to a dotted-line position to the right of FIG. 2 in which it can be donned with a fresh supply coil or it can be pivoted to the left to the dotted-line position in which the depleted supply coil is doffed therefrom by the pivotable doffing member 21.
  • the mandrel 19 is moved to the clotting position only after a sensing member (not shown) responds to the absence of yarn between the supply cop and the tensioner 18, indicating that the supply coil is exhausted.
  • the dofling member 21 pivots counterclockwise and ejects the empty core of the exhausted supply coil from the mandrel.
  • the coil then drops in the direction of the associated arrow onto a conveyor belt 22 which carries it away from the machine.
  • the mandrel In the donning position of the mandrel 19, the mandrel is located on a trough-shaped slide 23 having an upwardly extending trough-shaped slideway upon which a new supply cop discharged from the trough 37 in a manner hereinafter described, lies in readiness.
  • a latch 24 keeps the new supply cop supported on the slideway 25 from sliding down into the slide 23.
  • the latch 24 is moved downwardly so as to permit the cop to slide from its position on the slideway 25 downwardly to its position shown 'by the dot and dash lines on the slide 23 onto the mandrel 19 which is thereafter turned upwardly to place the cop in the unwinding position shown by the solid lines.
  • the latch 24 is actuated by a linking rod which engages an elongated slot 26 that is firmly secured to the shaft on which the mandrel 19 pivots.
  • a linking rod which engages an elongated slot 26 that is firmly secured to the shaft on which the mandrel 19 pivots.
  • a rocker arm 29 pivotable on frame 11 is linked to the dofiing member 21 and is connected through a linking rod located beneath the linking rod 40 to a driving arm of a rotatable suction tube 30, in a manner such as is shown in Patent No.
  • a feeler arm 41 pivoted at 46 to the frame structure 11 of the machine and actuated by the individual chain members of the conveyor 7 is located above the readying slideway 25.
  • Each trough 37 is provided with a nose 44 that presses upon a nose engaging feeler lever 43 as the trough 37 passes a winding station.
  • the consequent motion of the feeler lever 43 is then transferred by a spring 76 onto a rod 42 connected by an arm 77 with the feeler 41.
  • the feeler 41 is prevented from following the swinging movement of the nose engaging feeler lever 43 so that the spring 76 becomes compressed by the movement of the lever 43.
  • the rod 42 and the stop collar 47 attached thereto tend to reciprocate horizontally under the action of the lever 43.
  • the stop 47 abuts the nose 50 of the closure member 39 and turns the latter counterclockwise so that the cop can drop down from its position on the trough 37 to the position in the slideway 25 if no cop is already present in the slideway 25.
  • the feeler arm 41 prevents the rod 42 from reciprocating.
  • Stop collar 47 therefore cannot abut the closure member 39 and the swinging action of the feeler 43 is taken up by the spring 76 without moving the rod 42.
  • the swinging motion of the lever 43 is performed by inclined planes against which the lower end of the nose 44 strikes and is more fully described in Patent No. 3,111,280.
  • the individual spinning cops drop from the magazine container 4 through a chute 5 into the readying station 6 of the winding machine where they are supported by a readying plate 60.
  • the cop When the cop is located on the plate 60, it lies opposite the tappet 10 that is controlled through suitable linkages by a cam disc driven by a motor, both not shown but of the type of mechanism described in Patent No. 3,111,280, which shifts the cop from its position on the plate 60 to a position on top of the pair of rollers 61, 62 (FIG. 1, FIG. 3).
  • the length of the slot at the top of the nozzle 160 as shown in FIG. 4 for example is approximately equal to the length of the cop up to the conical portion at the tip of the cop.
  • the roller pairs 61, 62 are located at the foot of the coil core opposite a displaceable tubular nozzle member 218 which can be moved as shown in FIG. 4 toward and over the foot of the cop that is located on the rollers 61, 62.
  • the tubular member 218 and the elongated slot nozzle 160 communicate with a suction conduit 201.
  • a hinged valve or flap 221 actuated by an arm 222 selectively connects either the tubular member 218 or the slot nozzle 160 with a source of negative pressure (not shown). The movement of the hinged valve 221 takes place simultaneously with the tilting movement of the tubular member 218 in a manner described and shown in detail in Patent No. 3,111,280.
  • a bell crank lever or arm member 203 provided with an end hook 204 is pivotably mounted above the tip of the cop core.
  • the arm member 203 After the arm member 203 reaches the position substantially as shown in FIG. 5, it is pivoted to the position shown in FIG. 6 by the hereinafter described mechanism shown diagrammatically in FIG. 5 in a counterclockwise direction and the hook 204 thereby engages and pulls the yarn end slightly out of the slotted suction tube 160 so that a portion of the yarn extends in front of the right-side bore opening at the tip of the coil core.
  • the suction member 218 is simultaneously placed opposite the foot of'the coil core so that a suction current is produced through the bore of the cop core.
  • the yarn lying in front of the cop tip as shown in FIG. 6 is thereby seized by the suction current and is drawn into the bore of the coil core after a portion of the yarn end extending from the hook 204 into the slotted suction tube 160 is severed by a scissors 210 located on the side of the suction tube 160.
  • the severed portion of the yarn end is then sucked away through the suction channel 201.
  • the yarn end now extending from the cop as shown in FIG. 7 is then sucked into the bore 209 of the cop core.
  • a gravity-operated pin 205 is slidingly' connected to the arm member 203, on a component arm extending from said arm member 203.
  • the pin 205 has a rear portion bent back on itself so as to provide a slideway for sliding on a peg carried by the component arm that extends from the arm member 203.
  • a point is provided at the free end of the pin 205.
  • FIG. 5 An example of a mechanism for pivoting the arm member 203 and actuating the scissors 210 is illustrated diagrammatically in FIG. 5.
  • a normally open switch S is closed by the counterclockwise movement of the arm 222 when it actuates the flap 221 to connect the suction conduit 201 with the tubular member 218, which has simultaneously been placed over the foot of the cop by the mechanism described in Patent No. 3,111,280.
  • the solenoid R is consequently energized by the power source E to move the plunger P pivotably connected to the arm member 203, against the restoring bias of the compression spring 250 toward the right side of FIG. 5 so as to place the arm member 203 in the position shown in FIG. 6 in which the yarn end is entrained by the hook 204.
  • the arm member closes a normally open switch S energizing the solenoid R whose plunger actuates the scissors 210 which severs the yarn end that is sucked away in the suction conduit 201.
  • a mechanism for pivoting the arm member 203 and actuating the scissors 210 can also be mechanically or hydraulically operated and can furthermore take an entirely different form from that shown schematically in FIG. 5 just as long as the desired movement of the arm member 203 and scissors 210 is effected.
  • the embodiment shown and described is that of a spinning cop which is provided with a reserve winding at the foot of the cop 4, as has been mentioned before, the invention also has within its scope a means of readying the cop which has only a final number of steep turns or windings but has more reserve windings at the foot of the coil core. Consequently, in a manner similar to that described herein it is also possible to unwind a reserve coil or tip bunch located at the tip of the cop core and to insert these yarn ends into the bore of the cop core by suction in accordance with our apparatus and method. Individual devices for carrying out separate operations have already been suggested in many different forms, so that a separate description thereof is necessary since they do not anticipate the invention of this application.
