Definitions

  • the invention relates to a doffer device and its operating method with the features in the preamble of the main method and device claim.
  • Such a doffer device is known from DE 200 12 778 Ul. It is part of a coil system and contains one or more doffers that interact with one or more coil devices or so-called winders.
  • the doffers each have a spool changer and a sleeve changer.
  • Spool changers take over the bobbins completed by Winder individually or in the form of multi-spool doffs, whereby in turn new empty tubes are transferred from the tube changer to the winder.
  • the bobbins or doffs picked up by the doffer can be delivered to a magazine, a transport device or the like. At the same or a different location, the doffer can get new empty tubes with the tube changer. Alternatively, he can also carry a larger empty tube magazine.
  • the empty sleeves must be positioned on the mandrels of the winders with a certain axial distance.
  • a similar winder with spacing of the empty tubes on the mandrel is also known from DE 24 55 116 Bl.
  • the invention solves this problem with the features in the main claim.
  • the required axial distance between the empty tubes on the mandrels of the winders is formed before or during the tube transfer from the tube changer to the winder. This saves time and construction work.
  • the sleeve changer has a device for forming a distance between the empty sleeves. This enables the core changer to position the core at the necessary distance for the winder and to transfer it to the mandrel of the winder in one go.
  • the spacing of the empty tubes can be done during the tube transfer. Alternatively, it can also be done on the tube changer before the tube transfer in non-time-critical phases, for example when new empty tubes are being picked up. Thanks to the faster sleeve transfer and the associated distance formation, the entire changing process can run faster and more safely. This is particularly advantageous for applications with extremely short winding times of the bobbins of approx. 4 to 20 minutes, such as occur, for example, with relatively thick carpet yarns. In addition, the construction and tax expenditure is simplified.
  • the doffer device can also include the winder.
  • the winder can be made simpler, it being possible to dispense with the distance-forming mechanism on the mandrels. With conventional winders, this existing mechanism can be switched off, bridged or removed. The winder then only needs to clamp or hold the empty sleeves in place. This simplifies the construction of the winder.
  • the doffer can in particular be stationary and have a slide for the tube changer and the bobbin changer, which only carries out vertical lifting and lowering movements. In this case, it is advantageous if the doffer is connected to a drinking device for the coils and the empty tubes.
  • the doffer can operate two or more winders next to each other and have a simple travel axis with end stops. But it can also have a more complex chassis and travel longer distances.
  • the high exchange speed of the empty tubes and also of the full spools enables a particularly compact, small design.
  • the sleeve changer can be arranged substantially vertically under the coil changer. This also simplifies the design of the components on the carriage of the doffer.
  • FIG. 1 a section of a coil system with several doffer devices
  • FIGS. 2 and 3 enlarged representations of the doffer devices of FIG. 1 in various operating positions and functions
  • FIG. 7 a perspective top view of a sleeve changer
  • FIG. 10 a perspective view of a gripping device of the sleeve changer
  • Figure 15 a functional sequence in the transfer of the sleeves to a winder
  • Figure 16 is a perspective view of components of the bobbin changer.
  • Figure 1 shows a section of a bobbin system (2) in which filament bobbins (7) are produced.
  • This can be, for example, bobbins (7) with carpet yarns that are mechanically relatively insensitive and have short winding times. Otherwise, any other spools (7) can be produced from textile fiber materials.
  • the bobbins (7) consist of a central empty tube (8, 9, 10) which is wound with the filament or fiber material in a winding device (3), a so-called winder.
  • Several coils (7) can be wound at the same time and for this purpose are placed one behind the other on one or more mandrels (4, 5) of the winder (3).
  • the empty sleeves (8, 9, 10) are arranged one behind the other on the mandrels (4, 5) at an axial distance and clamped there in a suitable manner or held in some other way.
  • the mandrels (4, 5) move on a circular path around a central axis of rotation, which is aligned parallel to the mandrel axes.
  • Several coils (7) arranged one behind the other are usually also referred to as doffs (6).
  • a doffer device (1) is provided for this. This consists of at least one or more doffers (11), each of which is equipped with a sleeve changer (13) and a coil changer (14).
  • the doffer (11) are preferably designed as a stationary doffer (11) with a stationary vertical stand (15) and a carriage (16) which is driven in a vertically movable and controlled manner.
  • the sleeve changer (13) and the coil changer (14) are arranged on the slide (16).
  • the doffer (11) In the lower slide position, the full spools (7) can be taken over by the winder (3) and replaced with new empty tubes (8,9,10). This can be done in one go.
  • the doffer (11) In the upper carriage position, the doffer (11) is connected to a transport device (12) which is designed, for example, as a monorail overhead conveyor on which carriers for receiving the coils (7) or doffs (6) are movably mounted.
  • the carriers or carriages have pins for receiving individual coils (7) or doffs (6).
  • the carriers also have empty sleeve magazines.
  • the doffer (11) In the upper carriage position, the doffer (11) can deliver the bobbins (7) or doffs (6) that have been taken over to the transport device (12) and, in return, can take over new empty tubes (8, 9, 10).
  • the sleeve changer (13) always carries a load of empty sleeves (8, 9, 10) which are sufficient for loading a single mandrel (4, 5) on the winder (3).
  • an empty tube magazine can also be provided on the tube changer (13), which can hold a larger empty tube stock.
  • the sleeve changer (13) has a device (18) for axial spacing between the empty sleeves (8, 9, 10).
  • the empty tubes (8, 9, 10) are already pre-positioned on the tube changer (13) at a distance and transferred to the mandrel (4, 5) with the correct distance position. The formation of the distance can alternatively take place later when the empty sleeves (8, 9, 10) are transferred to the winder (3).
  • the winder (3) can also be part of the doffer device (1) and has a simplified mandrel mechanism with which the empty sleeves (8,9,10), which are positioned at a distance from the sleeve changer (13), are clamped from the mandrel (4,5) to be excited and held. There is no need for a separate mechanism for the winder (3) for forming the distance between the empty tubes (8, 9, 10).
