Definitions

  • the invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 16.
  • the coil transport e.g. from roving bobbins to a spinning machine, is carried out automatically in modern spinning mills with a transport system in which these bobbins are transported in groups or individually overhead.
  • the coils are usually carried by hanging pins, which are attached to coil trains that are guided by a drive system in railways. Such a system is e.g. can be seen from EP-OS 392482.
  • an adhesive strip was applied to secure the outer winding layers of the coil in the area of the head shoulder. It has been proposed to use this adhesive strip e.g. to apply with a spray gun. The application of this adhesive strip on the head shoulder is intended to exert a sufficient retention force on the outer turns of the yarn to ensure that if the withdrawal of the yarn from the bobbin is interrupted, the reduction in tension during the withdrawal is not transferred to the yarn of the bobbin becomes.
  • the type of securing the outer bobbin winding is used especially for yarn bobbins, which serve as a template for a subsequent processing process.
  • attaching an adhesive strip in this form is not suitable to secure the sliver end of a roving bobbin. As a rule, the sliver end is located between the two conical ends of the coil. This means that attaching an adhesive strip to a cone part would not be able to prevent a partial unwinding of the outer turns.
  • the adhesive can be rolled up, dabbed on or sprayed on.
  • the adhesive With a selected spray pressure between 3 and 5 bar and a corresponding distance between 10 and 20 mm to the surface of the spool, the adhesive can be sprayed on in a correspondingly dosed manner without causing damage to the roving wound on the spool. This means that the adhesive connects the second to last turn with the third and last turn. However, the adhesive should not reach the bottom, that is, the penultimate layer.
  • the additional agent adheresive
  • the coil can be aligned in a predetermined position if the spraying is carried out with freely suspended coils.
  • a corresponding spraying device can be easily assigned to the coil, especially since the spraying device and the coil surface are at a fixed distance during the transfer over a certain time.
  • the adhesive can also be applied, for example, in the area immediately after the transfer device if the coil is already on the second transport system.
  • the discontinuous transport of the coils during the transfer process is used. This means that every time the transport device has been moved by one step or a mounting spigot after a bobbin handover, the next bobbin to be secured takes a stop position in the positioned position in relation to a spray gun, in which the adhesive is sprayed on, until the next transport step can.
  • a coil In combination with match sticking, a coil can be identified by adding a dye.
  • This dye which can also be a marking dye, is mixed in a certain ratio with the addition of wetting agent and is water-soluble and washable.
  • This dye can be mixed with the adhesive before or during application to the spool.
  • the application device can consist of a nozzle of a spray gun which is at a distance from the coil surface and which applies the adhesive to the coil in the area of the last turn.
  • a water-soluble adhesive In order to avoid adverse effects on subsequent processing processes, such as color defects in the fabric, it is proposed to use a water-soluble adhesive.
  • the spray gun is attached to a pivotable arm, which is used to transfer the coils is provided between the transport devices, the time interval in which the spray gun and the coil surface assume a fixed position can be increased. This means that the adhesive can be applied during the swiveling process.
  • the spray gun For a more variable adaptation of the spray gun to the circumference of the coil, it is also proposed to attach it coaxially to an axis of rotation of a pivotable arm. This makes it possible for the spray gun to be able to move with respect to the position relative to the surface of the coil during the spraying operation, and thus to allow the adhesive point to be enlarged in the circumferential direction of the coil. Instead of moving the spray gun, the use of a second spray gun is also conceivable.
  • the further proposal to mount the applicator device or the spray gun in a height-adjustable manner enables an adaptation with respect to the longitudinal axis of the coil and, on the other hand, enables the application of more than three adjacent turns with an adhesive layer.
  • This height adjustment can also be carried out via a drive, as a result of which a certain vertical area on the surface of the spool can be wetted during the application process of the adhesive.
  • This shielding device can consist, for example, of an annular air channel which is generated by a second air nozzle assigned to the spray nozzle in the spray direction of the nozzle.
  • the spray gun can be assigned a switchable or deliverable cleaning device.
  • a cleaning device for example, a rotating brush that can be fed to the outlet of the nozzle could be used.
  • Cleaning is not only to be understood to mean the removal of external contaminants which get into the area of the nozzle, but also the cleaning of the application device or spray gun itself. This is particularly necessary when a paint substance is added to the adhesive in the spray gun and the change to a different color substance is desired.
  • the mixing chamber inside the spray gun must be cleaned of the old paint substance with an additional solvent.
  • the solvent is introduced into this mixing chamber and sprayed with the dissolved parts from the nozzle of the spray gun onto a collecting device.
  • This collecting device could, for example, consist of a collecting container that can be fed to the nozzle.
  • Figure 1 shows a schematic top view of a roving machine, e.g. a flyer 1 and a spinning machine, e.g. a ring spinning machine 2, which are connected to one another via the bobbin transport devices 3 and 4.
  • the transport device 3 on the flyer 1 is also generally referred to as a flyer doffer.
  • the transport device 3 serves to receive the full bobbins 5 delivered by the flyer 1 and also to return empty sleeves to the flyer 1 which have been transported back by the ring spinning machine 2. In the example shown, the delivery of only ten coils 5 is shown. In practice, however, there are significantly more coils that are released for further transport.
  • the details of the transport systems 3, 4 are not shown in detail.
  • the transport system could be, for example, elements guided in rails with pick-up pins for the coils, as shown, for example, in EP-OS 394708.
  • the drive, which is used to move the coils 5 within the transport systems 3, 4, is shown schematically with the position 24 and the control unit 25 in the transport system 4. In the transport system 3, only the control unit 26 for the output is indicated.
  • the transfer device 6 is shown on an enlarged scale and will now be described in more detail.

  • the shaft 10 is rotatably mounted in a frame 11 fixed to the floor and axially immovable.
  • the telescopic arm 7 is mounted in a vertically displaceable manner via a cylinder 13.

  • the shaft 10 is in the area of the bearing of the arm 7 with a longitudinal profile, e.g. a serration on which the arm 7 can be moved vertically. This profiling on the shaft piece 22 enables vertical displacement on the one hand and, on the other hand, entrainment during the rotary movement of the shaft 10 in the horizontal direction of the telescopic arm 7.
  • This rotary movement is generated in the example shown by a motor 28 which, via a spur gear 29 with a gear 30 in Drive connection is established, which is rotatably connected to the shaft 10.
  • the motor 28 is controlled by a control unit 31, which signals from end stops 44 and 46 are transmitted to limit the horizontal pivoting movement of the arm 7. (Fig. 2).
