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 applicable, a direct coupling with the spinning machines have therefore become widespread.
  • the preparation devices Tn generally contain several substations in which the beginning of the thread is sought, it cannot be found in some cases. Too too To be able to prepare these cops has already been proposed in DE-PS 30 45 825 to feed these cops to the preparation device again and again in a circuit. Apart from the fact that, according to this solution, the cops are subject to high mechanical stress, they remain in the circuit for a long time and thus reduce the output of properly prepared cops.
  • the object of the invention is to propose an automatic winding machine with a bobbin and tube transport system with a plurality of 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 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 provide circuits, for example in the form of transport disks, for 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 pallets 41 on the spinning machine side.
  • the supply of these spinning cops 5 with their pallets 4 from the conveyor belt 55 takes place via a guide edge 55 ⁇ 'on the main feed belt 7.
  • another sensor 12 which is arranged on a branch formed by a chute 14, indicates that a pallet 4 is present in the area of this chute 14, that is, a backlog on the Conveyor belt 16 has arisen, causes a control unit 10 via a control line 11 'that the switch 11 is 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 on the chute 15, whereby 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 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 continuously driven by the motors 17 and 19 via drive rollers 16 'and 18'. You are deflected by the pulleys 16 ⁇ and 18 ⁇ at the other end.
  • the preparation stages will be explained later with reference to FIGS. 2 to 4.
  • the cops 5 After leaving the third preparation stage 22 or 22 ', the cops 5 arrive with their pallets 4 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 guide 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 guide roller 26olle at the other end.
  • This reversing belt 28 is driven by a motor 29 via a drive roller 28 'in alternating directions and deflected at the other end by a guide roller 28'.
  • 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.
  • These branch tracks 3 can consist of conveyor belts which are driven by a continuous drive roller 3 'and a continuous deflection shaft 3' are deflected.
  • the drive shaft 3 ' receives its drive from a motor 103.
  • the branch tracks 3 can also have several parallel drive belts. It is also possible to take the drive from the return belt 32 instead of by the motor 3 Motor '.
  • the pallets 4 arranged in the branch path 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 draw a new pallet when a group of such pallets 4 passes this branch conveyor 3 on the reversing belt 28. This is possible because the branch track 3 projects into the area of the reversing track in which the narrower reversing belt 28 runs so that it does not cover the conveyor belts of the branch tracks 3. By arranging stops 31 and 31 'at the two ends of the reversing belt 28, the transport area of the pallets 4 is fixed.
  • 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 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 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 from the winding unit not processable cops 5 ', from the preparation device not prepared cops 5', sleeves with little thread remainder 6 'and empty sleeves 6 the winding unit 2 could no longer expose the beginning of the thread.
  • 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 that this sensor 33 distinguishes between cops 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 via a line 33 'to a control device 34.
  • 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 guide roller 36'.
  • a further sensor 38 is arranged on the secondary transport path formed by the conveyor belt 36 and detects when the winding residue exceeds a predetermined dimension. The sensor 38 then gives 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. If a minimum winding is undershot, the switch 40 remains closed, so that the pallet 4 is diverted to the transport path 41.
