  • a overhead conveyor is provided with spool receptacles, which are attached to lifting devices in order to lower the spool receptacles and thus to be able to take over the spools previously placed on the conveyor belt.
  • the spool can only be transported in one direction, i.e. it is not possible to remove, e.g. Pick up empty bobbin adapters and then fill them with fully wound bobbins.
  • a device according to the preamble of claim 1 is described in EP 00 26 160.
  • This known device is used to combine two axially aligned individual coils one behind the other by means of the coil adapter to form a coil group, which is then dropped under the influence of gravity into a storage device or a collecting trolley.
  • the individual coil adapters are previously removed from a coil magazine.
  • the coil units stored in the storage or collecting trolley must be recorded again, with practically only manual removal being suitable for the gentle removal of these coil units.
  • DE-OS 38 02 900 deals with a coil transfer or.
  • Bobbin transfer device for connecting an automatic winder to a double-wire twisting machine. It is in particular a device in which bobbins are removed from a conveyor belt by means of a gripper and, after changing the axial position of the bobbins, are delivered to bobbin carriers of a conveyor belt rotating around a double-wire twisting machine.
  • the solution according to the characterizing part of patent claim 1 creates the possibility, for example, of detecting and conveying horizontally aligned coils coming from an automatic winder by means of a coil adapter such that they are passed together as a unit with the coil adapter and aligned vertically to a hanging conveyor and be promoted to a processing machine.
  • the transfer or Conversion device is characterized in particular by the fact that in the area of the further processing machine, the reel adapters that have become free can be used again for equipping with individual coils or groups of coils, namely by means of the overhead conveyor device that freed or empty reel adapters that previously contained the units composed of coils and adapters has promoted the area of the further processing machine, be conveyed back into the area of the lifting cylinder unit attached to the rotary head.
  • the solution according to the invention essentially consists in assigning the bobbin transfer or bobbin transfer station to a bobbin transport device such that empty bobbin adapters returning from the processing machine are picked up, then fitted with fully wound bobbins and then again as units consisting of individual bobbins or bobbin groups and bobbin adapters transferred to the bobbin transport device and conveyed to the area of the further processing machine.
  • the device according to the invention has, according to FIGS. 2 to 4, three individual units, namely a coil feed unit A, the transfer unit B and the overhead conveyor device C.
  • the coil feed assembly A comprises as essential individual parts a machine frame 30 with a horizontal conveyor device 31 for feeding individual coils or coil groups 17, 17.1.

  • the belt conveyor 32, the extendable lifting element 34 and the spool holder 35 are designed such that, according to FIG. 4, spools 17, 17.1 conveyed on the belt conveyor 32 are removed from the belt conveyor 32 by raising the spool holder 35 and, for example, into a position according to FIG. 2 and 3 can be started.
  • the transfer unit B contains a stationary column 13 on which the carriage 14 can be moved up and down.
  • the carriage 14 carries a rotary head 2 which can be rotated about a horizontal axis and to which a lifting cylinder unit 1 is fastened with the lifting element 1.1 which can be moved in and out.
  • a coil adapter carrier 7 is attached to this extendable lifting element 1.1, consisting of a stop plate 8 and a mandrel 9.
  • the coil transport device designed as a hanging conveyor device C comprises a top rail 4, in which a conveyor chain or a conveyor belt is guided, on which bobbin hanging holders 5 are fastened at regular intervals.
  • the coil unit D consisting of the two coils 17, 17.1 and the coil adapter 6 can again be transferred to the free coil suspension holder 5 by raising the slide 14.
  • the carriage 14 is lowered again so far that the lower end of the coil adapter 6 is released from the mandrel 9, so that the coil unit D last released can be conveyed one step further.
  • the next coil adapter comes into the area of the transfer unit B, so that the described working cycle can begin again, namely removal of the coil adapter 6 from the coil suspension holder 5, etc.
  • a coil unit D can also comprise only one coil 17 and one coil adapter 6.
  • the mandrel 9 is provided with a preferably radially directed positioning pin 10, while the coil adapter 6 is provided on its inside with oblique and / or spiral guide surfaces 11 and a downwardly open latching groove 12.
  • the coil adapter is rotated in the direction of the arrows f1 or f2 by the interaction of the guide surfaces 11 with the positioning pin 10 until the positioning pin 10 engages in the latching groove 12.
  • a certain relative position between the coil adapter 6 and the mandrel 9 is achieved when the dome 9 is moved into the coil adapter 6.

  • This possibility of causing the carrier or the bobbin unit D to rotate has the purpose of locating the free thread ends after sucking up a suction device 16 on the lateral surfaces of the bobbins 17, 17.1 and sucking them into the suction device.
  • the suction device 16 can have one or more suction nozzles with elongated, vertically oriented nozzle slots which can be adjusted individually or together on the coils 17, 17.1.
  • the rotary head 2 has a further rotary device, the axis of rotation of which is perpendicular to the horizontal axis of rotation of the rotary head 2.
  • This further rotating device is preferably used to drive the coil adapter carrier 7.
  • a thread driver 18 shown in FIG. 5 is arranged such that its V-shaped driving notch 18.1, for example, grips the two threads F1 and F2 which are still under tension as a result of the suction effect of the suction device 16 when it is raised in the direction of arrow f3 and upwards to a thread clamp 19 promotes that can be actuated either pneumatically or electrically to grasp and clamp the two threads.
  • the thread clamp 19 can be brought up to the upper end of the bobbin adapter by means of suitable horizontal and vertical supports and associated actuators after gripping the two threads so that the two threads F1 and F2 can be guided in front of an opening 20 located at the upper end of the bobbin adapter 6.
  • this first opening 20 is followed by a thread guide channel 21 which is guided in the circumferential direction over a predetermined circumferential angle and leads to a second opening 22 in the lateral surface of the bobbin adapter 6.
  • the front nozzle end of a suction nozzle 23 can be inserted into this second opening 22 and is mounted on a bracket 25 of the machine frame by means of a lifting rod 24.
  • a suction hose 26 is connected to the suction nozzle 23.
  • a cutting device 36 is attached within the suction nozzle 23 in order to cut threads that have been sucked in with a defined length.
  • the two threads F1 and F2 are brought from the thread clamp 19 to the inlet opening 20 of the adapter, and if the suction nozzle is acted upon by suction air after the suction nozzle 23 has been moved into the opening 21, the two threads can be released from the suction air after loosening the thread clamp 19 are sucked into the suction nozzle 23, essentially as a function of the thread lengths which have previously been sucked into the suction device 16.
  • the suction nozzle After switching off the suction air effective in the area of the suction nozzle 23, the suction nozzle is again put away from the bobbin adapter 6, so that the ends of the two threads F1 and F2 then hang out of the outlet opening 21 with defined, uniform thread lengths.
