Definitions
- the invention relates to a winding machine for winding a thread into bobbins according to the preamble of claim 1.
- the thread produced from a polymer melt is wound into a coil after it has been drawn off and treated.
- the coil is used to store the thread and is then fed into a further processing process. So that the extrusion and the production of the thread can take place continuously in the melt spinning process, the thread is continuously wound into the spools without any major interruption.
- winding machines which have two winding spindles projecting on a rotatably mounted winding turret.
- the winding spindles can be guided alternately into an operating area and a changing area by rotating the winding turret. In the operating area, the thread is wound on the respective winding spindle to form the coil.
- the winding spindle with the full bobbin is guided into the changing area.
- the thread is wound on the circumference of the full bobbin to form a final winding and is then caught and severed by the bobbin spindle held in the operating area.
- the thread is then wound into a new coil.
- the full bobbin held in the changing area is removed from the bobbin spindle after the bobbin spindle has been braked and fed to a further processing step.
- a loose thread end that occurs on the final winding must remain as possible on the circumference of the full bobbin in order to avoid unwanted unwinding during the removal of the full bobbin from the winding spindles and during transport.
- a generic winding machine is known from DE 44 13885 AI, with softer winding spindles an auxiliary device is assigned that has a nozzle for wetting the thread with a water or has a preparation medium.
- the nozzle is guided to the thread wound as the final winding.
- the thread is then wetted before it is severed in order to ensure that the thread adheres to the circumference of the full bobbin as far as possible.
- the auxiliary device can optionally have a pressure roller, which is applied to the circumference of the full bobbin.
- a pressure roller which is applied to the circumference of the full bobbin.
- the film of fluid applied to the circumference of a pressure roller leads to very superficial wetting of the final winding. This meant that the loose end of the thread could only stick to the full bobbin for a short time.
- the auxiliary device has a means which interacts with the fluid dispenser and has a variable-shape delivery area, the delivery area wetted with a fluid being able to be guided on the circumference of the final winding of the full coil.
- the invention has the particular advantage that, in particular, the final turn produced with parallel turns can be intensively wetted. Due to the variability in shape and in particular the flexibility of the dispensing area, contact that is optimally adapted to the surface structure of the full coil is possible, so that the dispensing area wetted with a fluid applies the fluid evenly. Furthermore, pressure loads and thus mechanical impairments on the circumference of the full spool can be avoided. Due to the flexibility of the dispensing area, there are no pressure loads on the circumference of the full spool.
- the development of the invention is preferably designed in which the delivery area is flat towards one contact side and has a width that is at least three times as large as a thickness. A relatively large contact zone for applying the fluid to the circumference of the full coil can thus be implemented.
- variable-shape dispensing area has a plurality of dispensing elements, which are preferably each designed to be variable in shape independently of one another.
- the means with a variable-shape release area is particularly preferably a brush.
- a respective delivery element of the plurality of delivery elements is designed as a bristle or as a flexible strip.
- the fluid is applied by the brush using a large number of bristles which are preferably formed by horsehair.
- the further development of the invention is preferably designed in which the fluid dispenser is connected to the means, preferably the brush, by a hose line and an open hose is assigned to the agent.
- the fluid dispenser is connected to the means, preferably the brush, by a hose line and an open hose is assigned to the agent.
- the embodiment in which the hose end of the hose line opens into a piece of pipe closed on one side and in which the piece of pipe extends transversely to the means, in particular the brush and has several outlet bores on a longitudinal side facing the brush, has proven particularly successful. A uniform supply of the fluid is thus guaranteed over the entire width, in particular the width of the brush.
- the development of the invention is provided in which a bristle holder of the brush is attached to a carrier and in which the carrier can be guided by a pivoting arm between a rest position and an operating position. In this way, the brush can only be moved into the operating position when required to wet a full spool.
- the swivel arm can be positioned by a controllable movement actuator in such a way that the means, in particular the brush, is held on the circumference of the full bobbin until the full bobbin has come to a standstill on the circumference of the winding spindle.
- the contact of the delivery area, the means for braking the full bobbin can be used at the same time and, on the other hand, it is ensured that the loose end of the thread is guided through the delivery area, in particular the brush, into the final winding. In this way, the loose end of the thread can even be guided into the gaps in the final winding.
- the fluid dispenser has a metering pump which is connected to the hose line and through which a fluid can be conveyed at intervals.
- the fluid can thus be supplied as required. Since such winding machines are preferably used for winding up several threads whose bobbins are held one behind the other on the winding spindles, the further development of the invention is preferably implemented in which the winding spindles are assigned several winding points for winding several threads into a bobbin and in which several Means, in particular brushes are assigned to the winding positions, which are connected together with the fluid dispenser. It is thus possible to wet a plurality of full bobbins on one of the bobbin spindles in order to lead their loose thread ends to the final windings.
- the carrier is aligned parallel to the winding spindles and holds a plurality of holders arranged at a distance from one another, in particular bristle holders for the brushes.

- the traversing device 8 is coupled to a yaw drive 9.
- a changeover device 14 is provided on the machine frame 1, through which the thread of the winding point 1 and the adjacent threads of the winding points 4.2 and 4.3 are guided and cut during a bobbin change.
- the bobbin change is carried out between the bobbin spindles 3.1 and 3.2, so that the bobbin spindle 3.1 is in the changing area with several full bobbins 13 and the bobbin spindle 3.2 is in the operating area for winding new bobbins.
- the changing device 14 is pivoted between the winding spindles 3.1 and 3.2 and has already severed the thread, so that a loose thread end 31 is formed on the full bobbin 13.
