Definitions

  • the invention relates to an automatic winder according to the preamble of claim 1.
  • Modern spinning machines have a high output of spinning cops, which also places increased demands on the processing capacity of the downstream winding machines. It is therefore necessary to use a high degree of automation. Closed transport cycles in the area of the winding machine and, if necessary, a direct coupling with the spinning machines have therefore become widespread.
  • FR-A-2 513 666 corresponds to the preamble of claim 1, which is based on a closed pallet circuit between the spinning and winding machine.
  • the object of the invention is to propose an automatic winding machine with a bobbin and tube transport system with several transport loops, the processing capacity of which is suitable for the high output of freshly spun cops from the spinning machine.
  • the arrangement of different preparation devices in different transport loops makes it possible to prepare cops that are not easily prepared outside a main transport path. This means that these cops no longer burden the main transport route. So there can be a very short cycle time within a first preparation device can be realized since this preparation device is only set to copes which are easier to prepare and which form the vast majority.
  • the number of cops that are transported to a second preparation device in a second transport loop is significantly less than the number of cops that can be prepared by the first preparation device. This makes it possible to significantly increase the cycle time in the second preparation device. In this way, the probability of success of the preparation even of these cops in the second preparation device can be increased to almost 100 percent. These cops are then also fed back to the winding machine.
  • first preparation devices which are arranged on separate conveyor belts. This measure allows a further considerable increase in the processing capacity when preparing the cop. Since, according to the invention, the cops, which cannot be prepared in a first preparation device, are fed to second preparation devices, it is not necessary to add circuits, for example in the form of transport disks, to these first preparation devices form. This means that these first preparation devices can be arranged directly on a feed conveyor belt. The space saved in this way makes it possible to arrange several, possibly parallel, transport tracks with first preparation devices without increasing the dimensions of the machine.
  • these preparation devices can be integrated directly into the area of the winding machine sections, which reduces the overall length.
  • the second preparation devices are designed as a head cone preparation, it is advantageous to feed the cops from demolition parts of the spinning machine directly to this second preparation.
  • the arrangement of a sleeve cleaning device on a secondary transport path also serves to ensure a high processing capacity.
  • a first transport loop which is formed from main transport routes, essentially consists of the conveyor belts 7, 16, 18, 24, 26, 28, 3, 32 and 55. Furthermore, the slides 14 and 15 also belong to this transport loop.
  • the pallets 4 circulating in the transport loops of the winding machine 1 are loaded in the region of a conveyor belt 55 by means of a converter 60 which transfers the spinning cops 5 from pallet 4 'on the spinning machine side.
  • These spinning cops 5 with their pallets 4 are fed from the conveyor belt 55 via a guide edge 55 ′′ ’to the main feed belt 7.
  • a control unit 10 via a control line 11 'causes the switch 11 to be opened so that the pallet 4 passing the sensor 9 is passed on the main feed belt 7 past the slide 14.
  • the switch 11 it is also possible to control the switch 11 in such a way that it alternately guides a pallet 4 into the chute 14 and releases the next pallet for forwarding on the main feed belt 7. This pallet 4 is later deflected by a leading edge 7 '''from the main feed belt 7 onto the chute 15, as a result of which it reaches the conveyor belt 18.
  • the first preparation devices 23 and 23 ' are arranged on the two conveyor belts 16 and 18, which form parts of the main feed path.
  • These preparation devices 23 and 23 ' have a modular structure, that is to say they can be varied in terms of the arrangement and number of their substations according to a modular system and in the present example each consist of three preparation stages 20, 21, 22 or 20', 21 'and 22' .
  • These preparation stages each contain drives 73 (see FIGS. 2 to 4) which position the respective pallet 4 on the conveyor belt 16 or 18. It is therefore possible that these conveyor belts 16 and 18 are driven continuously by the motors 17 and 19 via drive rollers 16 'and 18'. They are deflected by the deflection rollers 16 '' and 18 '' at the other end.
  • the preparation stages will be explained later with reference to FIGS. 2 to 4.
  • the cops 5 with their pallets 4 arrive on the conveyor belts 24 and 26.
  • the feed to these conveyor belts is supported in each case by guide edges 24''' and 26 ''.
  • the conveyor belt 24 is driven by a motor 25 via a drive roller 24 'and deflected by a deflection roller 24''at the other end.
  • the conveyor belt 26 is driven by a motor 27 via a drive roller 26 'and deflected by a deflection roller 26''at the other end.
  • the spinning cops 5 reach a reversing belt 28.
  • This reversing belt 28 is driven by a motor 29 via a drive roller 28 'in alternating directions and deflected by a deflection roller 28' 'at the other end.
  • the motor is controlled via a control line 30 'by a control unit 30 with an inverter.
  • the direction reversal of the transport direction of the reversing belt 28 is advantageously carried out according to a predetermined time rhythm.
  • the pallets 4 are guided on the reversing belt 28 past the branch webs 3 leading to the winding stations 2.
  • branch tracks 3 can consist of conveyor belts which are driven by a continuous drive roller 3 'and are deflected by a continuous deflection shaft 3' '.
  • the drive shaft 3 ' receives its drive from a motor 103.
  • the branch tracks 3 can also have a plurality of parallel drive belts. It is also possible to remove the drive from the return belt 32 instead of using the motor 103.
  • the pallets 4 arranged in the branch web 3 are moved further in the direction of the return belt 32. This creates a gap on the branch conveyor at the end facing the reversing belt 28, into which the conveyor belt or conveyors in the region of the branch conveyor 3 pull a new pallet when a group of such pallets 4 passes this branch conveyor 3 on the reversing belt 28.
  • the transport area of the pallets 4 is defined by the arrangement of stops 31 and 31 ′ on the ends of the reversing belt 28 on both sides.
  • the sensor 9 described at the beginning can also be designed as a color sensor which, in the event that the bobbin winder 1 is supplied with different sections of yarn, determines which color the pallet 4 passing by or the sleeve 6 of the cop 5 passing by has. Since it is common to use sleeves or pallets of different colors for different lots, the lot can be recognized from the respective color. In this case, a partition would have to be arranged in the area of the reversing belt 28 between the conveyor belts 24 and 26, which then separates the winding areas for the different lots. The sensor would give the information about the detected color to the control unit 10 via the line 9 '. This control unit 10 would then control the switch 11 via the control line 11 '.
  • the preparation devices 23 and 23 ' are arranged on the conveyor belts 16 and 18, which form parts of the main feed paths, and no further branches are provided in front of the reversing belt 28, a secondary transport path branches off with a conveyor belt 36 which is only a second one Transport loop heard, only from the return belt 32.
  • the return belt 32 transports cops 5 'which cannot be processed by the winding unit, cops 5''which are not prepared by the preparation device, cores with a small amount of thread 6' and empty cores 6.
  • Copts 5 'which cannot be processed by the winding unit are to be understood as which the winding unit 2 could no longer expose the beginning of the thread. These are, in particular, cops that have already been partially unwound, but still have so much thread material that it is worth repeating them in the winding unit 2.
  • a sensor 33 is arranged on the return belt 32, which detects that there is still residual thread on the incoming tube. It is not necessary for this sensor 33 to distinguish between copes 5 'which cannot be processed from the winding station and sleeves 6' with a small thread residue. If windings still present on the sleeve 6 are detected, the sensor 33 signals this to a control device 34 via a line 33 ′. This control device 34 controls the switch 35 via a control line 34 ′, which then swivels into the area of the return belt 32. The respective pallet 4 is then directed into the secondary transport path, which is formed by the conveyor belt 36.
  • the conveyor belt 36 is driven by a motor 37 via drive roller 36 'and deflected by means of a deflection roller 36' '.
  • a further sensor 38 is arranged on the secondary transport path formed by the conveyor belt 36, which detects when the winding residue exceeds a predetermined dimension. The sensor 38 then sends a corresponding signal to the control unit 39 via a line 38 '.
  • This control unit 39 opens a switch 40 via a control line 39'.
  • the relevant pallet 4 is conveyed further along a transport path 41 on the conveyor belt 36.
  • the switch 40 remains closed, so that the pallet 4 is diverted to the transport route 41.
  • This transport path 41 can likewise be formed by a transport belt which is driven in a controlled manner by appropriate devices within a sleeve cleaning device 42.
  • Sleeve cleaning devices are generally known.
  • a sleeve cleaning device could be used, as described in DE-AS 24 18 492.

  • the turns remaining on the sleeve can be separated by a circular knife, which is held at a corresponding distance from the sleeve by means of a sensor.
  • the separated thread material can be removed from the sleeve by a blowing nozzle.
  • a corresponding suction device would then have to be provided.
  • the pallet 4 with the now cleaned sleeve 6 arrives on a conveyor belt 43, a guide edge 43 ′′ providing additional guidance.
  • the conveyor belt 43 is driven by a motor 44 via a drive roller 43 'and deflected by a deflection roller 43''.
  • the pallet 4 with the sleeve 6 comes back to the return belt 32. There it then passes the sensor 33 and reaches the conveyor belt 55 through the open switch 35 via the leading edge 32 ′′ ′′.
  • the sensor 33 again recognizes residual threads on the sleeve 6 '.
  • the pallet 4 with the sleeve 6 ' is again passed through the switch 35 onto the conveyor belt 36 and fed to the sleeve cleaning device 42.
  • the conveyor belt 45 is driven by a motor 46 via a drive roller 45 ′ and a deflection roller 45 ′′ is deflected.
  • a second preparation device 47 is arranged on this conveyor belt 45. This preparation device 47, which essentially searches for the beginning of the thread on the head cone, is not bound in its mode of operation by the short cycle times that are specified on main transport tracks.
  • the conveyor belt 45 can run much slower than, for example, the conveyor belts 16 and 18 on the main feed path.
  • the motor 46 can be operated directly by the second preparation device 47 via a control, not shown.
  • the structure of this preparation device 47 will be explained later with reference to FIG. 6. It also has a sensor, not shown here, which monitors the detection of the beginning of the thread, as described, for example, in DE-OS 20 24 110.
  • This sensor can control a switch 48 via a control line 47 '. If the beginning of the thread has been found, the switch 48 closes, so that the pallet is deflected onto a conveyor belt 49.
  • This conveyor belt 49 is driven by a motor 50 via a drive roller 49 'and deflected by a deflection roller 49' '. This conveyor belt 49 then feeds the pallet 4 directly back to the main feed belt 7.
  • the cop 5 'or 5' 'then arrives again in the first preparation device 23 or 23'.
  • the second preparation device 47 merely loosens the beginning of the thread and deposits it in the area of the cop coat.
  • the switch 48 is opened via the control line 47 '.
  • the conveyor belt 45 transports the pallet 4 further to a guide edge 45 ′′ ′′, where it is deflected onto a further conveyor belt 51.
  • This conveyor belt 51 is driven by a motor 52 via drive roller 51 'and deflected by a deflection roller 51''.
  • This motor can also be controlled directly by the second preparation device 47 via a control line 47 ′′. As a result, it is only in operation for a time after a cop 5 'or 5'', which is also not prepared in the second preparation device, switches the switch 48 on the Conveyor belt 45 has passed.
  • the conveyor belt 51 forms a storage section together with a stop 53.
  • the cops 5 'or 5''collected in this storage section must be prepared manually. However, since such cops, which could not be prepared by either of the two preparation devices, in particular due to the considerably longer cycle time and the different structure of the second preparation device, are the absolute exception, the storage sections need to be looked after very rarely.
  • a conveyor belt 57 which belongs to a closed loop around the ring spinning machine, is arranged in parallel. Between these two conveyor belts, the empty sleeves 6 are transferred or the freshly spun cops 5 are taken over. For this purpose, converters 60 and 69 are arranged between the two conveyor tracks 55 and 57. Since this implementation must be clocked, additional sensors and stop devices are required.
  • a sensor 70 is thus arranged at the end of the return conveyor 32, which transmits the information via a line 70 'to a control unit 68 as to whether pallets 4 are still available on the return conveyor 32. These pallets 4 are stopped by a stopper 70 ′′ in the area of the conveyor belt 55.
