  • a sleeve ejection device 49 is rotatably mounted about an axis of rotation 50.
  • the sleeve ejector 49 is designed as a two-armed lever, the arm 51 being held in a lower position by a spring 52 and the second arm 53 being acted upon by a cylinder 54 which is pivotably articulated on the frame of the combing machine 5.
  • a plate 56 is rotatably fastened about an axis 57. The plate 56 is held in an upward position by a spring 58 which engages an extension piece 59 of the plate 56.
  • the plate 56 In the position shown in dashed lines, the plate 56 assumes a blocking position for the ejected sleeve 4, which rolls back over the rolling plate 55. 1 and 2, the plate 56 is slightly bent at its free end and extends with this end into the vertical range of motion of the cross bar 40 when the arm 37 is in the pivoted down position (X, Y).
  • the rod 40 is provided with side guides 60 which are arranged at regular intervals and by means of which the sleeves 4 are fixed laterally in a receiving position. This positioning is necessary for the transfer to the grippers 7.
  • the operation of the combing machine 5 is stopped and the rest of the wadding still on the sleeve 4 is removed.
  • This can e.g. carried out by a method which is described in EP-OS 437 807.
  • the sleeve ejector 49 is actuated via the cylinder 54 and transfers the sleeve 4 resting on the winding rollers 47, 48 from position I to position II on the rolling plate 55.
  • the release of the sleeve ejector 49 or the cylinder 54 takes place by switching the compressed air supply from a compressed air source 62 via a valve 63, which is switched through by a control unit 64.
  • the valve 63 is switched through when the control unit 64 receives the signal "sleeve expired" via line 65 from sensor 61 and the signal "residual cotton removed from sleeve” from control unit 66 via line 67.
  • the control unit 68 receives the corresponding signal from the sensor 61 via the line 69.
  • sensors 70 are attached to the crossmember 10 and monitor whether there are already grippers 7 with a reserve winding 3 or empty reels 4 picked up by grippers in the area of the transfer station 1.
  • This sensor 70 which was again indicated schematically in the lower part of FIG. 2, also transmits its signals to the control unit 68. If the sensor 70 has not detected any coils or sleeves, the control unit 68 transmits the to the drive 71 for the transport device Command "Provision of reserve windings".
  • the reserve winding 3 are now in one or two trains with four or eight windings, which are suspended in grippers 7 fed to the transfer station 1 and moved into the guide rails 9.
  • the positioning of the trains within the transfer station 1 takes place, as already described above, via the latch 25, which, as is also indicated schematically below in FIG. 2, sends a signal to the control unit 68 via a sensor “train started and positioned” which is not shown in any more detail submit.
  • the valve 72 is switched through via the control unit 68, as a result of which the compressed air source 62 acts on the cylinder 19 with compressed air.
  • the rope 21 moves upward in the column 15 and rolls over the guide rollers 22.
  • this process is only carried out when the lever 37 is in the X position.
  • the reserve reels 3 are also only moved into the guide rails 9 when the control unit 68 is reported “rails 9 in the uppermost position” (sensor 46) and lever 37 in position X “(sensor 45) or transmitted to the control unit 68 via the line 73.
  • the position II of the ejected sleeve 4 is monitored by a sensor 75, which emits a corresponding signal to the control unit 68 via the line 76. Before the sensor 75 does not output the "empty sleeve present" signal , the lowering process is also not triggered.
  • a sensor 77 for example a proximity sensor
  • this message is also transmitted to the control unit 64, as a result of which the compressed air supply via the valve 63 to the cylinder 54 is interrupted again and the sleeve ejector is returned to its lower starting position via the spring 52.
  • the sensor 75 was again shown schematically next to the control unit 64.
  • a sensor 79 When the lower dash-dotted position of the crossbeam 10 is reached, a sensor 79 is actuated and emits its signal via a line 80 to the control unit 68. The compressed air supply to the cylinder 19 or 20 via the valve 72 is now interrupted.
  • This stop signal is transmitted via line 86 to control unit 84 and line 87 to control unit 68.
  • the control unit 84 now switches through the valve 88, which actuates the cylinder 42 pressurized with compressed air.
  • the arm 37 pivots into the upper, solid position and the sleeve 4 assumes the position IV.
  • the pivoting movement is stopped by a sensor 45.
  • This stop command is transmitted via line 89 to control unit 81 and control unit 68.
  • control units 64, 66, 68, 81 and 84 for controlling the corresponding valves were shown in the exemplary embodiment in a separate arrangement for reasons of clarity.
  • control units are combined in a central control unit.
  • the proposed device according to the invention thus offers a fully automatic possibility of changing the reels or the empty sleeves via a transfer station on a combing machine or also for other reel processing machines.
  • the design according to the invention is not only limited to such lowering stations, but can also be used in connection with a carriage transport.
