DETAILED DESCRIPTION OF THE INVENTION

(7) FIGS. 1 and 2 show in perspective view one of the workstations 1 of a winding machine arranged in a row next to one another.

(8) On such workstations 1 spinning cops 2 preferably produced on ring spinning machines, which comprise relatively little yarn material, are rewound into large volume cross wound bobbins 3, wherein the thread 4 is also monitored during the rewinding process for thread faults, which are removed if necessary.

(9) The cross wound bobbins 3 are mounted freely rotatably respectively in a bobbin frame 5 during the winding process and are rotated during the winding process by a thread guiding drum 6, which also ensures that the thread 4 unwound from the spinning cop 2 is traversed correctly whilst running onto the cross wound bobbin 3.

(10) Thread processing and monitoring devices are already known which are required in connection with the rewinding of such feed bobbins and the removal of thread faults and which are arranged on said workstations respectively in the region of the thread path. As said thread processing and monitoring devices are not relevant to the subject matter of the invention, said known devices are not represented and described in more detail.

(11) As shown in FIG. 1 each of the workstations 2 has a rotatably mounted round magazine 7 for storing a plurality of spinning cops 2.

(12) The round magazines 7 each comprise for example nine magazine pockets 8 for spinning cops 2. A loading shaft 10 is arranged underneath the round magazine 7 and is mounted with limited rotation about a pivot axis 9, which loading shaft can be positioned by means of a pneumatic cylinder 11 optionally in a position of rest or in a transfer position.

(13) Also a stationary mount 12 is arranged underneath the ejection opening of the round magazine 7, on which mount an additional spinning cop 2 can be deposited prior to commencing the winding process or onto which a spinning cop 2 slides when it leaves the round magazine 7 through the ejection opening and is thereby secured by the loading shaft 10 positioned in a position of rest.

(14) Each of the workstations 2 is also equipped with a pivotably mounted sleeve ejector 13, which can be positioned in a defined manner by means of a pneumatic cylinder 14.

(15) The LED light bar 15 is positioned on the lower part of the round magazine 7 and is attached to be inclined slightly upwards.

(16) In the embodiment of FIG. 2 the winding machine comprises an individual machine logistics device in the form of a cop and sleeve transport system 16, of which only the cop supply conveyor 17, the reversibly driven storage conveyor 18, one of the transverse transport conveyors 19 leading to the workstations and the tube return conveyor 20 are shown.

(17) In said cop and sleeve transport system 16 spinning cops 22 or empty tubes rotate on transport plates 21 which are positioned in vertical alignment.

(18) The supplied spinning cops 22 are thereby wound into large volume cross wound bobbins 23 in unwinding position AS, which is located respectively in the region of the transverse transport conveyors 19 at the workstations.

(19) The individual workstations have for this purpose, as already known and therefore only indicated, various different devices which ensure the correct operation of said workstations. Said known devices are for example a workstation control device 24, which is connected via a bus line 25 to the central control device 26 of the winding machine, a suction nozzle 28 which moves about a pivot axis 27 and can be charged with negative pressure, a gripper tube 30 which moves about a pivot axis 29 and can be charged with negative pressure and a pneumatic thread splicing device 31.

(20) The LED light bar 32 is advantageously attached inclined obliquely upwards onto the slightly upstream sleeve return conveyor 20 and is connected via a bus line 25 with both the workstations control devices 24 and the central control device 26. In the section of the LED light bar 32, which is assigned to the respective workstation, there are six individual LEDs. The first two LEDs indicate the batch allocation. In addition, the workstations 24 control the LED light bar 32 relative to the yarn batch so that the first two LEDs of the LED light bar 32 have an identical color at the workstations which are producing the same yarn batch. Batch 1 is identified by a yellow light and batch 2 by a blue light. The remaining four LEDs of the section are available for displaying operating states. If the lower thread is missing at this workstation and the workstation is idle, the LED light bar 32 is controlled so that the remaining LEDs flash red at a high frequency, so that the operating staff recognize that urgent steps need to be taken.

(21) FIG. 3 shows schematically in front view an open end rotor spinning machine 33 with end frames 34, 35 and a plurality of similar workstations 36 arranged between the end frames 34, 35.

(22) In the end frames 34 or 35, as is usual, there are for example a textile machine own source of negative pressure 37, an electric power supply and a central control unit 38 of the open end rotor spinning machine 33.

(23) The central control unit 38 is connected in turn to the workstation control devices 39 of the individual workstations 36, preferably via a bus system 40.

(24) The numerous workstations 36 each comprise a workstation housing 41 comprising an open end spinning device 42, a winding device 43, a suction nozzle 44 and additional known thread processing devices, such as for example a paraffining device 45.

(25) In the lower section of the spinning devices 42 is the LED light bar 52, which is connected via a bus system 40 to the workstation control devices 39, wherein the workstation control devices 39 control the LED light bar 52 according to the yarn batch and operating state.

(26) At the workstations 36 a feed fiber band 46 is spun into a thread 48 by means of the open end spinning device 42, which fiber band is stored in spinning cans 47 which are positioned in series next to one another below the workstations 36, and which thread is subsequently wound on the winding device 43 into a cross wound bobbin 49.

(27) The open end rotor spinning machine 33 is also equipped with a cross wound bobbin exchanger 50 which can be driven along the workstations 36, which if necessary exchanges finished cross wound bobbins 49 for fresh cross wound bobbin tubes.

(28) FIG. 4 shows schematically in front view two workstations of a ring spinning machine. The workstations are denoted here by the reference numerals 53A and 53B.

(29) As already known, such ring spinning machines on each of their longitudinal machine sides have a stationary spindle rail 54, in which spinning spindles 55 are arranged at an interval t, which are driven in the embodiment by means of a tangential belt 56.

(30) Above the stationary spindle rail 54 a vertically adjustable mounted ring rail 57 is arranged which, as indicated by arrow 58, can be moved by means of a (not shown in detail) drive mechanism according to a predefinable spinning program and is also provided with an LED light bar 69, which displays faults in the respective workstation 53A, 53B. Here five LEDs form the section, which is assigned to a workstation.

(31) In the ring rail 57 spinning rings 59 are installed on which ring travellers 61 circulate during the spinning operation charged by the running thread 60.

(32) The workstations 53A and 53B of the ring spinning machine are also equipped with a drafting system 62, between the lower rollers 63 and support rollers 64 of which the fiber band 65 to be spun is stretched, which preferably comes from a (not shown) roving bobbin which is suspended in an assigned creel.

(33) As shown schematically in FIG. 4, the ring spinning machine also comprises an interface 66, which is connected to the control device 67 of the ring spinning machine, which controls the position of the winding of the spinning cops and the displays of the LED light bar 69. The connecting line is denoted by the reference numeral 68.

(34) FIG. 5 shows a prespinning machine 70, also known as a roving, with a drafting system 71, winged table 72, wings 73 and spindle rail 74 and spindles 75. FIG. 5 shows the side view and thus the transverse extension of the prespinning machine. Underneath the drafting system 71 there is an essentially flat surface 76. The surface 76 extends from the area of the drafting system 71 up to the wing units 77. On the spindle rail 74 an LED light bar 84 is attached such that sections of the LED light bar 84 can be assigned to the individual workstations of the prespinning machine 70.

(35) In the spinning cans 78 there is a fiber roving. The fiber roving is guided over conveyor belts (not shown), which are secured to the support pipes 79, to the drafting system 71. The fiber roving runs through the drafting system 71 and is guided by the wing units 77 to the wings 73 and lastly wound onto not shown pre-yarn or roving bobbins which are arranged on the spindles 75. In longitudinal direction of the prespinning machine 70 a plurality of additional workstations are arranged.

(36) On the front side of the winged table 72, i.e. on the side of the surface 76 facing the wing units 77, a blowing device 80 is arranged which charges the surface 76 in the area below the drafting system 71 or above the winged table 72 with blown air over the whole area.

(37) On the opposite side, i.e. on the side facing the drafting system 71, a suction channel 81 extending in the longitudinal direction of the prespinning machine 70 is arranged. On the suction channel 81 a slide 82 is arranged with a suction opening 83 which moves along the suction channels 81 and removes impurities from the surface 76.
