Definitions

  • My invention relates to machines for Winding cross- Wound yarn packages, usually called cheeses or cones, in which the winding operation is automatically discontinued when the yarn package on a take-up spool is completed, whereafter a spool exchanging device removes the completed take-up spool or package and substitutes an empty spool core before the machine resumes the Winding operation to produce another yarn pack-age on the core.
  • my invention particularly relates to multi-station machines of the justmentioned type in which a number of individually operaible winding stations cooperate with a single take-up spool exchanging device relative to which the winding stations are placed into coactive position, one at a time, by relative movement between the winding stations on the one hand and the exchanging device on the other hand.
  • the relative movement is produced by displacing the winding stations with respect to the exchanging device or vice versa, the' travel being temporarily stopped during the period of time in which the device operates to effect the spool exchange.
  • a spool lay-off structure is provided at a take-up spool exchanging device in a cheese or cone winding machine generally of the above-mentioned type, the lay-01f structure having a surface area which receives from the exchanging device the completed take-up spool issuing at a time from the spool journalling location prior to insertion of an empty spool core into that location;
  • I further provide an intermittently operating spool feed device which is engageable with the laid-off spool on the just-mentioned receiving area of the lay-off structure and has a feed stroke approximately equal to the dimension of the completed take-up spool relative to the feed direction, so that the spool receiving area on the structure is vacated by the action of the feed device prior to arrival of the next spool.
  • the collecting structure can be arranged in such a manner that the arriving spools travel serially behind each other, either with their respective peripheral surfaces facing or engaging each other, or with their axial surfaces or cores facing or engaging each other.
  • the feed stroke of the above-mentioned feeder device corresponds at least approximately to the spool diameter, Whereas in 'the latter case the feed stroke corresponds approximately to the full axial width of the spools.
  • the feeder device comprises a reciprocating pusher member which, actuated for example under control by the takeup spool exchanging device, shoves each arriving spool away from the arrival area.
  • the collecting structure is such that the cross-wound yarn packages may engage each other at the peripheral surfaces, these surfaces may possibly rub against each other and become damaged if the structure is designed as a trough.
  • the collecting structure it is preferable to design the collecting structure as -a conveyor belt which is controlled by the spool exchanging device to move intermittently for shifting each spool away from the arrival location an amount at least equal to the spool diameter.
  • a feed device in form of a stepwise operating conveyor belt may also be used if the spools are placed with their axial ends facing each other, in which case the conveyor belt moves, upon each spool exchange, an amount at least approximately equal to the axial length of the spool.
  • a particularly gentle handling of the spools is secured if such a conveyor belt is equipped with individual trays or shells into which the yarn packages are placed at the arrival location.
  • the completed cross-wound spools are collected in a most gentle manner until they are removed from the collecting structure by the attending personnel and placed into suitable containers, such as transportation boxes.
  • the automatic take-up spool exchanging device in a yarn winding machine is provided with control means that comprise a sensing device responsive to rotation of the take-up spool on the wind-up journalling location of the machine, so that the spool exchanging operation is initiated only after the completed take-up spool, upon stop-- ping of the winder drive, has fully or nearly reached standstill.
  • control means that comprise a sensing device responsive to rotation of the take-up spool on the wind-up journalling location of the machine, so that the spool exchanging operation is initiated only after the completed take-up spool, upon stop-- ping of the winder drive, has fully or nearly reached standstill.
  • a rotation sensing device may be provided for each of the winding stations in the machine, or a single sensing device may be employed and preferably mounted on the spool exchanging device for coaction with only the one winding station that is in coactive position relative to the exchanging device at a time.
  • the just-mentioned rotation sensing device comprises a feeler which mechanically engages the take-up spool at the journalling means, at least when the spool has reached a given diameter or size, and which is displaced or turned as long as the spool is in rotation, thus controlling an electric control circuit, such as by opening of a contact, when the spool reaches standstill.
  • the sensor may also be of the proximity type so as to operate without entering into bodily contact with the spool.
  • the sensor proper may consist of a heat-responsive member which senses the change in temperature resulting from the motion of air that occurs near the spool surface as long as the spool has an appreciable speed of rotation.
  • a heat sensor consists of a temperature-responsive electric resistance (thermistor) connected in a resistance bridge network.
  • thermistor temperature-responsive electric resistance
  • the thermistor When the spool is in rotation, the thermistor is subjected to cooling, and under these conditions the bridge network is balanced by adjustment of one of its other resistors.
  • the thermistor increases and its resistance changes so that the bridge network becomes unbalanced with the effect of controlling a circuit to operate the spool exchanging device.
  • the rotation sensing device may essentially consist of a generator driven from the take-up spool and connected with a magnet which, as long as the generator is in rotation, opens a contact in the control circuit of the exchange device.

  • the motor 14 drives the yarnguiding drum 15 (FIG. 1) which rotates the spool 3 in the winding-up sense, due to the fact that the spool rests frictionally upon the drum 15 under the weight of the spool holder 2 and of the spool itself.
  • the spool frame 2 is gradually lifted and moves the arm 6 away from the shoulder 8 of lever 9.
  • the lever 9 When the spool attains a predetermined size, the lever 9 is triggered by the force of the pull spring 11 and turns clockwise, thus opening the contact 12 so that the energizing circuit of the winder drive motor 14 is interrupted and the spool decelerates to standstill.
  • the closing of contact 16 energizes the coil 101 of a control relay or contactor CR2 from source 17 through leads 50 and 51.
  • Relay CR2 actuates main contacts 102, 103 and a normally open interlock contact 104.
  • Contact 103 now energizes a stepping motor 18 (FIGS. 13, 1) which is mechanical-1y connected with a control shaft 19 and remains energized only during the period of time needed to rotate the shaft 19 360, thus also imparting a single full rotation to a number of control cams mounted on the shaft 19 as will be explained in a later place.
  • the relay contact 102 simultaneously opens the circuit 20, 21 of the above-mentioned motor 22 (FIGS. 13, 1) for driving the machine structure 1, so that the winding station remains stopped opposite the servicing unit 5 (FIG. 1) until the exchange of the take-up spool is completed.

  • Leads 28 and 29 are connected to respective brush contacts 26a and 26b for energizing the spool releasing device CR from the current source 17.
  • the energizing circuit is normally interrupted by a contact 32.
  • Another cam 30 (FIGS. 13, 4) fastened on the above-mentioned single-turn shaft 19 to rotate together therewith, is engaged by a follower 31 which controls the contact 32.
  • the follower 31 enters temporarily into a cam recess 33 thus closing the contact 32 and energizing the spool releasing device CR through leads 28, 24, 25 and 29.

  • the above-mentioned single turn of shaft 19 causes the cam 34 to swing the magazine 37 downward toward the journalling location of the spool-holder frame 2. Since the full spool previously completed has already been released, the lowermost core in the magazine now reaches the journalling location where it remains for a short interval of time, sufiicient for the spool releasing device to become deenergized by opening of the above-mentioned contact 32. As a result, the core becomes now clamped in the frame and remains held and journalled therein when thereafter the magazine 37 is swung upwardly back to the starting position illustrated in FIG. 1.

  • the yarn packages completed on the winding machine when being exchanged for an empty core, are so laid off upon the collecting or transporting structure that a collision between the packages is reliably prevented.
  • Such packages as cheeses and cones can therefore he removed from the collecting location by the attending personnel in larger intervals of time than previously permissible, without the danger that the yarn turns of the packages may become entangled or otherwise disarranged, until they are placed upon suitable transporting racks, creel carriages, conveyor carriages, boxes, pin boards or the like auxiliary devices.
