Definitions

  • the invention relates to a method for producing a package, in which the yarn carriers spun in a ring spinning machine are rewound to form packages in a downstream rewinding machine, and a device for carrying out this method.
  • Cross-wound bobbins are produced by means of cross-wound bobbins and automatic machines on which yarn carriers known as cops are unwound and rewound into cross-wound bobbins, the bobbin being checked for errors and elimination at the same time.
  • the yarn carriers are manufactured in the spinning mill and transported to the rewinding machines. Ring spinning machines are used almost exclusively to manufacture the yarn carriers.
  • Such a network system already has a relatively high degree of automation.
  • the spinning of the yarn carriers, the preparation for doffing them, the spinning stop and the lifting of the yarn carriers from the spinning spindles and placing them on the conveyor belt take place on the ring spinning machine.
  • the ring spinning machine then grips the empty thread carriers from the conveyor belt and places them on the spinning spindles and then starts the spinning process.
  • After the yarn carriers have been spun they are carried out on the conveyor belt to the cheese winder, at the same time the empty yarn carrier is placed on the conveyor belt. In this way, the automatic transport of the full yarn carriers from the ring spinning machine to the cheese winder and the automatic return transport of the empty tubes from the cheese winder to the spinning machine is realized.
  • the yarn carriers are removed from the conveyor belt of the ring spinning machine and transferred to the transport system of the cross winder.
  • the thread is searched for and held in the thread carrier, whereupon the thread carrier is transported to the winding unit. There the thread is gripped and connected to the thread of the package, whereupon the thread is unwound from the thread carrier.
  • the empty yarn carrier is then inspected with regard to the yarn residue and then the empty yarn carrier is returned to the conveyor belt of the ring spinning machine, where the empty yarn carrier is transferred to the conveyor belt.
  • Automatic piecing machines that can perform various functions are also used in ring spinning machines. These patrol along the spinning machine. If a thread break is found, the Automatic piecing machine stopped, the spindle stopped and lifted off the spinning spindle. The end of the thread is searched for on the thread carrier, whereupon the thread carrier is put back on the spinning spindle, the ring traveler is threaded in and the thread is attached to the delivery cylinder of the drafting system. The attaching machine then continues patrolling.
  • This object is achieved according to the invention in that the rewinding of the yarn carriers into cross-wound bobbins is carried out on the ring spinning machine itself.
  • the invention also includes a device, the task of which is to enable the method to be carried out optimally.
  • a rewinding device is attached to the ring spinning machine for each group of spinning stations, on which a winding station for rewinding the yarn carriers spun on the spinning stations into cross-wound bobbins and a gripping device for removing and feeding the yarn carriers from and to one Spinning station and for transporting the yarn carrier from and to the winding station are arranged.
  • the invention is based on the consideration that a reduction in the outlay for the production of a package can be achieved by unwinding the yarn carrier spun in the ring spinning machine if the unwinding of the yarn carriers arriving from the ring spinning machine is carried out directly on the ring spinning machine or on the relevant spinning station he follows. It is essential that the ring spinning machine does not have to be changed in terms of design. Merely the mode of operation becomes somewhat different insofar as the full spool of thread is no longer removed from the spinning stations and empty spool of thread is put on at the same time, but each spinning station spins the thread spool until it is full, whereupon it is removed and an empty tube is put on.
  • a rewinding device is used, which is arranged on the long side of the ring spinning machine. It is essential here that a rewinding device is permanently assigned to a group of spinning stations. This means that a conveyor belt, as is used in the known composite system, can be dispensed with. It is useful if the areas of the individual groups overlap.
  • the rewinding device 12 shown in FIG. 1 is arranged on the long side of a ring spinning machine 1.
  • the ring spinning machine 1 is any known model, of which essentially only those parts are schematically shown that are related to the present invention.
  • the structure of the ring spinning machine 1 is assumed to be known.
  • the spinning station 5 has a rotating spindle 6, on which a yarn carrier 7 in the form of a sleeve is placed.
  • the spindle 6 of the spinning station 5 is driven via a belt drive 8 by a common drive shaft 9 or by a single spindle drive.
  • the thread running onto the yarn carrier 7 is threaded into a rotating runner 10, which causes the spun yarn to be wound up by its rotation.
  • the left side of the figure is a mirror image, which is why it has been omitted.
  • the ring spinning machine handling devices are arranged, which are used to remove the full yarn carrier and to insert empty tubes.
  • a rewinding device 12 is shown, as it is required for the implementation of the inventive method.
  • the rewinding device 12 essentially consists of a winding unit 14 and a gripping device 15.
  • Such a rewinding device 12 is used for a group of spinning stations 5, with each group being assigned a rewinding device 12.
  • the winding unit 14 has a holder 16 for receiving a full yarn carrier 7, which is arranged at the foot of the winding unit 14.
  • the yarn end to be unwound is searched for and detected by a yarn carrier nozzle 19, see FIG. 3, while rotating the yarn carrier, a yarn connecting device 17 presented and connected to the package thread.
  • the nozzle 19 can be pivoted into the position shown in dashed lines.
  • the yarn connecting device can be a yarn knotter or a yarn splicer of a known type.
  • Control devices 18 are provided above the yarn connecting device 17, with which the yarn is examined for errors as it passes.
  • a cross-wound bobbin 20 Arranged above the control devices 18 is a cross-wound bobbin 20 which is driven by a rotating drive roller 21 on the circumference of the bobbin, the yarn to be wound being fed to the cross-wound bobbin 20 through a grooved drum and laid thereon.
  • Another yarn laying system can be used instead of the grooved drum.
  • the gripping device 15 of the rewinding device 12 has the task of performing all the necessary manipulations in order to maintain the spinning process with empty yarn carriers 7 '.
  • the gripping device 15 has a stand 22 on which a gripper arm 23 is rotatably guided and movable up and down.
  • the gripper arm 23 grasps the full yarn carrier 7, removes it from the spinning station 5, swivels it to the side and sets it in a waiting position.
  • the waiting position can be located on a turntable 24, where there are further positions for the reception of empty and full spools of thread.
  • the gripper arm 23 now grips an empty yarn carrier located on the turntable 24, lifts it and puts it on the spindle of the spinning station 5.
  • the gripper arm 23 can bring the full yarn carrier placed on the turntable 24 into the holder 16 of the winding station 14. where the thread is unwound and rewound to the package 20.
  • Two gripper arms can also be used, one of which is used for changing the yarn carrier 7 on the ring spinning machine and the other for changing from and to the unwinding point.
  • the only partially spun yarn carrier 7 is removed from the spinning station 5 by the gripper arm 23 in the same way as a full yarn carrier and brought into the waiting position on the turntable 24. There the partially full spool is unwound in the same way as a full spool.
  • the change of a thread carrier 7 on the spinning station 5 thus includes the detection of the end of the spinning process, the stopping of the spindle and the pulling of the thread carrier 7 by the gripper arm 23.
  • the rewinding device 12 can be used in two versions. Either both the winding unit 14 and the gripping device 15 can be moved, see FIG. 2, or the winding unit 14 is stationary and the gripping device 15 moves along the group of the spinning units 5 assigned to it, see FIG. 1. In both cases, the gripping device patrols 15, possibly together with the winding unit 14, within reach of the assigned spinning units 5 of the group, the yarn carrier 7 changes from the spinning spindle 6 directly into the unwinding position of the winding unit 14 or into a waiting position in front of the unwinding unit, for example on the turntable 24.
  • the full, partially full and empty spool 7 is only transported within the rewinding device 12.
  • the full spool 7 can be exchanged at the spinning stations 5 at any time, since the full spool is produced individually. Nevertheless, a time control for determining the operating time can be provided for each spinning station 5.
  • Rewinding can likewise take place during the patroling of the gripping device 14 or the entire rewinding device 12 or during the standstill of the winding station 14.
  • the individual spinning of the individual yarn carriers at the spindle positions 5 allows that when changing a full spool of thread can be spun on the other spinning positions 5.
  • a mobile rewinding device 12 is shown, in which both the winding unit 14 and the gripping device 15 are mobile.
  • the rewinding device 12 is designed as a carriage which is provided with rollers 25 which are guided on rails 26 which are fastened to the machine frame 4 of the ring spinning machine 1.
  • the ring spinning machine 1 is equipped with individual drives for the spindles 6.
  • Each spinning station 5 is equipped with a motor drive 27.
  • the provided for each spinning ring carrier 10 'with the rotor 10 is also moved by a motorized single drive 28 via a spindle drive 29 up and down.
  • FIG. 4 shows the ring spinning machine 1 with a mobile rewinding device 12.
  • the spindles are driven by individual drives 27, while the ring bench 10 ⁇ with the rotor 10 is moved up and down by the main drive of the ring spinning machine 1.
  • a single ring carrier drive can also be used.
  • the difference to FIG. 3 is that the unwinding of the yarn carrier 7 is carried out in the winding unit 5.
  • the yarn guide is shown here schematically in simplified form via deflection rollers 40. In this case, too, the yarn end is caught by a thread search nozzle and transferred to the thread connecting device 17.
  • the thread is then spun on by placing the yarn on the empty yarn carrier 7, as shown in FIG. 5.
  • a starter yarn 31 is drawn off and placed on an empty yarn carrier 7 ', e.g. clamped or wrapped.
  • the empty thread carrier 7 ' has a thread clamp 33.
  • the starter thread 31 is threaded on the rotor 10.
  • a feed arm 36 is pivoted out and the starter yarn 31 is taken along, whereupon the starter yarn 31 is cut by a cutter 37 and raised to the outlet cylinder of the drafting unit 3 and spun there.
  • the reserve spool 30 is expediently accommodated on the mobile winding unit 14. If the rewinding device 14 is stationary, the reserve reel 30 can be made movable with the gripping device 15.
  • the individual spinning at each spinning station 5 with a known ring bank entails, see FIG. 6, that instead of the usual cop winding, a winding called a random winding must be used, see FIGS. 6 a) and b).
  • a parallel winding c) and a combination winding d) are also shown.
  • the random winding b) is shown in two variants, which differ only in the movement of the ring bench. The movement sequence over time is shown in the two diagrams variant 1 and variant 2. Spinning can start at any point and be stopped. The ring bench periodically performs the same stroke movement.
  • the attachment of the rewinding device 12 to the ring spinning machine 1 simplifies the manufacture of a cheese.
  • the gripping device 15 can also be used to independently start the spinning spindle 6 when changing lots, i.e. be used when changing the roving or when changing the machine setting.
  • each spinning station 5 is changed individually while the other spindle stations 5 continue to run increases the production capacity.
  • a rewinding device 12 is required for each group of spinning stations 5. Spinning on the ring spinning machine can take place without loss of production if the number of yarn carriers 7 for each group is one or more yarn carriers larger than the number of spinning positions in a group.
  • the spinning station 5 is equipped with an individual ring carrier movement, a backward winding and an underwinding as in the known doffing method can be provided when the thread carrier is full, so that the known thread carrier change (doffing method) and the spinning start is possible without spinning with the rewinding device 12. If one wishes to dispense with automatic piecing and automatic thread breakage elimination, one can also carry out these processes manually and dispense with the device for automatic piecing shown in FIG. 5.
  • the yarn carrier nozzle can also be used to remove yarn residues from the yarn carrier after unwinding, for this purpose the thread carrier has to be turned. This can be done in the rewind position or in an adjacent position.
  • the rewinding device 12 can also take on additional functions, for example - Match stop - Blow off and clean the ring spinning machine - Monitoring the ring spinning machine by means of sensors - Change of the runner 10
  • the finished packages 20 are expediently placed on a conveyor belt and transported to the end of the ring spinning machine.
