Definitions

  • the invention relates to an automatic winding machine with a closed bobbin and tube transport system according to the preamble of the first claim.
  • Modern spinning machines have a high output of spinning cops, which also places higher demands on the processing capacity of the downstream winding machines. It is also necessary to feed the unwound sleeves in sufficient quantities to the spinning machine.
  • closed transport circuits in the area of the winding machine and, if necessary, a direct coupling with the spinning machines are widespread.
  • Well-known pallets have been used here for over 20 years, on which the cops or sleeves are placed and transported together with them.
  • DE-PS 33 36 958 describes a cop and sleeve transport system, on the sleeve return path of which a sleeve removal device and a sleeve delivery device are arranged in succession.
  • tubes with a small amount of residual thread are removed from the pallets and fed to a tube cleaning device.
  • the empty pallet is then transported on the return path to the tube delivery device, which must have a corresponding magazine in order to have a stock of tubes ready.
  • This delivery device only operates when an empty pallet arrives. The pallets must be stopped both on the tube removal device and on the tube delivery device.
  • the main transport loop includes a feed path of the spinning cops to the winding machine, branch lines through the winding units and a return path on which mostly empty cores are transported.
  • the empty tubes can be released from the pallets to the spinning machine and freshly spun cops can be picked up on these pallets.
  • preparation devices can also be arranged on the main transport loop. In any case, there is a closed pallet cycle. That is also why it is particularly important to recycle the pallets as quickly as possible.
  • a number of advantageous routes can be derived from the arrangement of the sleeve cleaning device on a secondary transport path.
  • the front can be Use the sensor located on the branch to check the successful cleaning of the sleeve.
  • a storage section is provided, which can also be used for unpreparable heads. This storage section is then operated by hand.
  • Pallets 1 with empty tubes 2, tubes 2 'with a small thread residue and tubes 2' 'with a thread residue that can still be processed arrive on a tube return path 17.
  • the sleeves 2 ′′ can also be cops 3, the thread end of which could not be detected either in a thread end preparation device located on the feed path or in the winding unit.
  • the reference symbol 2 ′′ is also used below for these cops 3.
  • the return path 17 initially leads past the exit side of branch webs which lead through the winding units of the winding machine.
  • the pallets 1 then pass further downstream a sensor 4 which detects whether there is still a thread residue on the sleeve 2 'or 2''.
  • This can be a known photo sensor which is arranged at a height at which the winding residue is normally located.
  • This sensor 4 is connected to a switch 5 via a line 4 '. If this sensor 4 has detected a winding residue, it controls the switch 5 so that it is pivoted into the return path 17. As a result, the pallet 1 with the sleeve 2 'is directed onto the conveyor belt 6.
  • This conveyor belt 6 is driven by a motor 8 via a drive roller 6 'and deflected by a deflection roller 6' '.
  • the pallet 1 is conveyed past a further sensor 21 to a switch 9, which deflects it onto a further conveyor belt 10 if the winding residue monitored by the sensor 21 on the sleeve 2 'is so small that further processing is ineffective .
  • the conveyor belt 10 is constantly driven by a motor 11 via a drive roller 10 'and deflected by a deflection roller 10' '. It leads through a sleeve cleaning device 18.
  • Such sleeve cleaning devices are generally known.
  • a sleeve cleaning device could be used, as described in DE-AS 24 18 492.
  • the pallet 1 with the sleeve 2 'could be stopped in the sleeve cleaning device 18 and the sleeve could additionally be positioned exactly by means of a holder which is placed on the sleeve from above.
  • 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 sleeve remains on the pallet during the cleaning process.
  • the pallet 1 with the now cleaned sleeve 2 reaches the conveyor belt 12 by means of a guide edge 10 ′′′.
  • the conveyor belt 12 is driven by a motor 13 via a drive roller 12 'and deflected by a deflection roller 12''.
  • This conveyor belt 12 conveys the pallet 1 with the sleeve 2 directly back onto the return path 17. It then passes the sensor 4 again, through which it then passes check whether the sleeve has been completely cleaned. If the sleeve still contains thread remnants, the switch 5 is switched again and the sleeve is again fed to the sleeve cleaning device 18.
  • the switch 9 is opened via a control line 21 ′.
  • the pallet 1 with the sleeve 2 ′′ is passed on directly to a conveyor belt 19.
  • the conveyor belts 6 and 19 are formed by a single conveyor belt.
  • a sensor 22 in the sleeve cleaning device 18 or following it, which checks the complete cleaning of the sleeve. If this sensor 22 still detects remaining threads, it drives a switch 20 via a line 22 ′, which in this case replaces the leading edge 10 ′′′.
  • the switch 20 is opened by the sensor 22, the pallet 1 with an incompletely cleaned sleeve 2 'is guided into a storage section 14. The rest of the wrapping can then be removed by hand.
  • the special thread end preparation device cannot prepare individual cops. These cops may not be fed to the winder, but can reach the storage section 14 via a conveyor belt 15.
  • the accumulation section 14 is filled only gradually. It is therefore sufficient if the operator operates this storage section during a tour and returns the pallets with cops 3 or sleeves 2 to the transport routes intended for them.
  • a further sensor 31 is arranged at the beginning of the storage section 14, which is also connected to the central control unit 27 via a line 31 ′. If this sensor 31 detects a standing pallet, which indicates the backlog, a suitable signal is first sent out via the central control unit 27 in order to call the operator. If the traffic jam then remains for a predefinable time, which the sensor 31 detects, the central control unit 27 blocks the switch 20 in the position shown in FIG. 2 via the line 20 '. This means that no further pallets 1 are inserted into the storage section 14.
  • the central control unit 27 can control the special thread end preparation device (not shown) or the route assigned to it in such a way that non-preparable sleeves 2 ′′ with a large amount of winding residue instead of the accumulation section 14 of the winding machine or in the area of the winding machine arranged further preparation devices are supplied. This control can then take place either with switches or, for example, with conveyor belts that can be reversed in their direction.
  • the central control unit 27 can open the switch 9 via a line (not shown here), which then clears the way for incoming pallets 1 to the conveyor belt 19 and thus possibly invalidates commands given by the multifunction selector 23 sets when this has recognized a sleeve 2 ', which should normally be fed to the sleeve cleaning device 18.
  • This sleeve 2 ' is then fed to the special thread end preparation device, which either has a sensor system which also recognizes that it is a sleeve 2' with a small amount of winding, so that this sleeve 2 'is then fed to the accumulation section 14.
  • sleeves 2 'and sleeves 2' 'can accumulate on the return path 17.
  • Another consequence of this may be that the sleeve cleaning device 18 and the special thread end preparation device (not shown) are overloaded, which can result in a backlog on the conveyor belt 6.
  • the switch 5 remains closed due to the winding residue detected by the sensor 4 or 23, the backlog would continue on the return belt 17, as a result of which the free passage of pallets 1 with sleeves 2 to the cop delivery station would be blocked.
  • a proximity sensor 32 shown in FIG. 2, which in this case could also be arranged further upstream of the transport direction of the conveyor belt 6, or a further sensor arranged upstream and not shown would detect a backlog on the conveyor belt 6. Via the central control unit, the special thread preparation device mentioned would then additionally allow the arriving sleeves 2 'and 2' 'to pass until the jam is cleared. However, this passage would only remain open until the sensor mentioned again recognizes larger distances between the pallets, thereby signaling the current reduction of the traffic jam.
  • let-through pallets 1 with sleeves 2 ′ or 2 ′′ are preferably passed around the winding machine, this transport path (not shown) opening into the return path 17.
  • the control described last ensures the full functionality of the transport system even in extreme cases in which known systems fail.
  • the senor 4 is replaced by a multifunction sensor 23.
  • This multifunction sensor 23 can distinguish between empty tubes 2, tubes 2 'with a small thread residue and tubes 2' 'with a thread residue that can still be processed. It is connected to switches 5 and 9 via control lines 23 'and 23' '.
  • the multifunction sensor 23 detects an empty sleeve 2, it controls the opening of the switch 5, so that this sleeve 2 with the pallet 1 on which it is placed can be transported further along the return path 17, for example to a sleeve removal device. If the multifunction sensor 23 detects a sleeve 2 'with a small amount of thread, it closes both switches 5 and 9 via the control lines 23' and 23 ''. As a result, the pallet 1 with the sleeve 2 'is conveyed via the conveyor belt 6 and the conveyor belt 10 of the sleeve cleaning device 18 fed. It is advantageous if the switch 9 has a delay circuit which only converts the signal of the multifunction sensor 23 after a certain period of time. This time period should be slightly less than the time that a pallet 1 needs from the multifunction sensor 23 to the switch 9.
  • the multifunction sensor 23 If the multifunction sensor 23 has recognized a sleeve 2 ′′ with a thread residue that can still be processed, it controls the closing of the switch 5 and the opening of the switch 9.
  • proximity sensors 24 to 26 are arranged before the junction of the secondary transport path 7 on the return path 17 and on the conveyor belt 12 and before the branching of the secondary transport path 7 on the return belt 17. These proximity switches 24 to 26 are connected to a central control unit 27 via lines 24 'to 26'. This central control unit 27 in turn has control lines 28 'and 29' to stoppers 28 and 29, which on Return belt 17 are each arranged in front of the junction and the junction of the secondary transport path 7.
  • the proximity switches 24 to 26 count the pallets 1 equipped with sleeves 2, 2 'and 2' '.
  • the stoppers 28 and 29 can be used to control how many pallets 1 enter the section of the return belt 17 between the junction and the branch of the secondary transport path 7. It can be monitored when a pallet 1 is conveyed from the secondary transport path 7 to the return path 17. In this case the stopper 28 is closed so that the pallet coming from the conveyor belt 12 is not prevented from entering the return belt 17 by pallets 1 transported along the return belt 17.
  • the use of this stopper 28 in connection with the proximity switch 24 also makes sense if, for example, a sensor 22 (FIG. 1) is arranged on the conveyor belt 10 to monitor the successful sleeve cleaning process.
  • the central control unit 27 determines whether a pallet 1 with a sleeve 2 or 2 'is opposite the multifunction sensor 23, which already has the secondary transport path 7 has gone through If this multifunction sensor 23 then detects (sensor 4 from the first example is also possible here) that there is still a thread residue on the sleeve 2 ', this means that the sleeve cleaning process in the sleeve cleaning device 18 was not successful.
  • the central control unit 27 controls the switch 20 via the line 20 ′, correspondingly with a time delay or by the described counting upon arrival of this pallet 1 in front of the switch 20, which clears the corresponding pallet 1 into the storage section 14.
  • the stop devices 28 and 29 also intercept the thrust, which adds up according to the number of collided pallets 1.
  • the use of the stopper 29 makes it possible to stop the respective pallet 1 with respect to the sensor 4 or 23, which increases the accuracy of the monitoring, in particular if only very small thread remnants have remained on the sleeve.
