Definitions

  • the present invention relates to a winding unit of a textile machine producing cheese, consisting of a base unit and a cover unit, the winding unit having a bobbin holder for holding a cheese and a traversing device for laying a thread crosswise on the cheese, a thread search device being provided for searching for a thread end on the cheese, the thread search device having a suction nozzle with a suction nozzle that can be subjected to negative pressure, the base unit is at least partially covered by the cover unit, the cover unit with respect to the base unit between a working position for laying the thread and searching for the thread end and a cleaning position for cleaning the
  • the winding station is movable and that at least parts of the thread search device are assigned to the cover unit, as well as a method for operating such a winding station.
  • the invention also relates to a method for operating a winding unit of a textile machine producing cheese, the winding unit consisting of a base unit and a cover unit, and where a thread is laid crosswise on the cheese using a traversing device, and a thread end is searched for on the cheese using a thread search device if necessary and the winding unit is cleaned at regular intervals.
  • Winding units of textile machines producing cheese cross-wound bobbins are well known.
  • the textile machine can be both a winding machine and a spinning machine, in particular a rotor or air-jet spinning machine.
  • a thread search device is provided in such winding units for searching for a thread end on the cheese.
  • the thread end runs up on the cheese in particular after a thread break or a cleaner cut, or if, for example, the delivery bobbin is empty.
  • the thread is intentionally cut because it does not have the desired properties, such as thickness or purity.
  • the cheese cannot be stopped quickly enough due to its inertia, so that the end of the thread runs onto the cheese.
  • a new thread can now be attached to the cheese. But then the thread is no longer continuous.
  • the accumulated thread end must be searched for and found.
  • the thread end is then connected to the thread coming from a delivery bobbin or, in the case of a spinning machine, to the freshly spun thread or attached to a spinning unit. In this way, the thread on the package remains continuous.
  • a suction nozzle to which negative pressure is applied is often used as the thread search device, which sucks in the accumulated thread end, as is described, for example, in the publications EP 2 444 347 A2 , DE 40 04 028 A1 , DE 10 2012 016 854 A1 or JP S59 31256 A is revealed.
  • thread search devices which brush the thread end from the surface of the cheese or those which blow the thread end off the surface of the cheese with the aid of compressed air.
  • the object of the present invention is thus to design a winding unit with a thread search device in which cleaning is facilitated.
  • a winding unit of a textile machine producing cross-wound bobbins is proposed.
  • the textile machine can be a winding machine or a spinning machine, in particular a rotor or air-jet spinning machine.
  • the winding unit consists of a base unit and a cover unit. It has a bobbin holder for holding a cheese and a traversing device for laying a thread crosswise on the cheese. These components are essential for the manufacture of a cheese.
  • a thread search device for searching for a thread end on the cheese.
  • a thread end runs onto the cheese after a thread break, a cleaner cut or when a delivery bobbin is empty.
  • the cheese can usually no longer be stopped in time to prevent the thread end from running up.
  • the accumulated thread In order to get a continuous thread on the package - which is important for the further use of the package - the accumulated thread must first be searched for and found. This step is carried out by the thread finder. Then, in the case of a winding machine, the thread end with the thread coming from the delivery bobbin connected or, in the case of a spinning machine, connected to the freshly spun thread or attached to a spinning unit. In this way a continuous thread is achieved.
  • the base unit is at least partially covered by the cover unit.
  • the parts of the base unit that are covered by the cover unit are significantly less exposed to flying dust and fluff than places that are not covered.
  • the cover unit can be moved with respect to the base unit between a working position for laying the thread and searching for the thread end and a cleaning position for cleaning the winding unit.
  • At least parts of the thread search device are assigned to the cover unit.
  • the cleaning position enables the operating personnel or a traveling cleaner or a robot with a cleaning device to access various points on the winding unit, which overall simplifies and improves cleaning. Because at least parts of the thread search device are assigned to the cover unit, these parts of the thread search device are also more accessible, which facilitates cleaning.
  • a first part of the suction nozzle is assigned to the base unit and a second part of the suction nozzle is assigned to the cover unit.
  • the two parts of the suction nozzle are thus removed from one another in the cleaning position, which facilitates access to these parts and thus also the cleaning of the parts.
  • the cover unit is displaceable, in particular rotatable and / or linearly displaceable with respect to the base unit, between the working position and the cleaning position.
  • These movements can be carried out easily and at the same time robustly, which makes the operation of the winding unit reliable.
  • rotating or sliding movements can be made can also easily be carried out by a motor, which enables the cleaning process to be automated. It is also possible to completely remove the cover unit from the working position, for example by loosening screws, and to attach or screw it on again in this working position.
  • the thread search device has a suction nozzle with a suction mouth that can be acted upon by negative pressure.
  • a suction opening of the suction mouth is positioned a short distance above the surface of the cheese.
  • the thread search with negative pressure is one of the gentlest thread search methods, since the surface of the cheese is not touched. The surface of the cheese is therefore only slightly damaged, if at all, which enables the cheese to be of high quality.
  • the suction mouth is movable with respect to the suction nozzle.
  • the distance from the suction port to the cheese should be variable. A larger distance can then be selected in normal winding operation, so that winding is not hindered and any damage to the cheese caused by the suction nozzle is avoided.
  • the suction mouth can be moved close to the surface of the cheese, so that the available negative pressure is optimally used. If the suction mouth is now movable with respect to the suction nozzle, then the distance from the suction mouth to the cheese can be changed by moving a component that is relatively small compared to the entire suction nozzle.
  • a drive means in particular a drive motor, is provided for moving the suction mouth. So can the The suction nozzle can be automatically moved into the position for thread search and back again. This is particularly advantageous for an automated spinning station: without such a drive means, the suction mouth would have to be brought into the desired position either by operating personnel or by a robot.
  • the suction mouth is advantageously rotatable and / or linearly displaceable with respect to the suction nozzle. With one or both of these movements, the suction mouth can be moved easily but precisely into the position for searching for the thread and back. In addition, rotary and linear sliding movements can be carried out particularly well by the drive means.
  • the suction port is assigned to the first part or the second part of the suction nozzle. So the suction port is not divided in the cleaning position. This also eliminates the need for edges and dividing joints, on which the thread found could otherwise rub, catch or jam. The thread is treated more gently, which benefits the quality of the product. In addition, the thread search process is less error-prone, which means that fewer interventions by the operating personnel or by robots are required and consequently the productivity of the textile machine is increased.
  • An interruption means is advantageously provided for interrupting the negative pressure in the cleaning position of the cover unit. Since no negative pressure is required to search for the thread in the cleaning position, this interruption means ensures that no negative pressure is consumed during cleaning.
  • a locking means is provided for locking the cover unit in its working position and / or cleaning position. This prevents accidental movement of the deck unit from one to the other position difficult.
  • the cover unit is then in defined positions, which in particular enables an exact position for searching for threads, but also enables precise cleaning for a cleaning unit.
  • the locking means can be unlocked manually and / or automatically.
  • the device is designed according to the preceding description, it being possible for the features mentioned to be present individually or in any combination.
  • the winding unit consists of a base unit and a cover unit.
  • a thread is laid crosswise on the cheese by means of a traversing device; if necessary, a thread end is searched for on the cheese using a thread search device and the winding unit is cleaned at time intervals.
  • thread searching when a thread end has run into the cheese, for example after a thread break, after a cleaner cut or when the delivery bobbin is empty.
  • the winding unit can be cleaned at fixed or variable time intervals. The latter could be, for example, whenever a traveling cleaner drives past the winding unit, or when the winding unit reports the need for cleaning, for example because a sensor detects a high level of soiling.
  • the cover unit For cleaning the winding unit, the cover unit is moved from a working position into a cleaning position with respect to the base unit, contaminants are removed from the winding unit and the cover unit is moved from the cleaning position back into the working position.
  • Moving the deck unit to the cleaning position gives access to certain areas Allows sharing of the winding unit and thus both facilitates and improves the cleaning of the winding unit. This results in both shorter cleaning times and a better cleaning result - and thus ultimately also a higher quality of the thread.
  • a better cleaning result means that more time can pass before the next cleaning and therefore the next standstill of the winding unit does not have to occur again until later. This also increases the productivity of the textile machine overall.
  • the cover unit is advantageously rotated and / or linearly shifted from the working position into the cleaning position and back with respect to the base unit. These movements are easy to perform, robust and quick. In particular, these movements can also be carried out very well automatically. It is also possible to completely remove the cover unit from the working position, for example by loosening screws, and to attach or screw it on again in this working position.
  • a suction nozzle assigned to the thread search device is subjected to negative pressure. Searching for the thread end with negative pressure is particularly gentle, since the surface of the cheese is not directly touched and the thread on the surface of the cheese is not damaged. A high quality of the thread produced is achieved in this way.
  • a suction port assigned to the suction nozzle is moved, in particular rotated and / or linearly displaced, with respect to the suction nozzle in the vicinity of the surface of the cheese.
  • the distance between the suction opening and the surface of the cheese can be adjusted in a simple but very effective way.
  • a rotary and / or linear sliding movement can also be easily automated become. Moving only the suction mouth in comparison to the entire suction nozzle also has the advantage that only a light part has to be moved and that less space is required for the movement.
  • the cover unit is locked in its working position and / or cleaning position. This prevents accidental movement of the deck unit.
  • the cover unit is then in a defined position, which is required both for searching for the thread end and for cleaning by a cleaning unit. Overall, the operation of the winding unit is simplified and improved by locking the cover unit.
  • Figure 1a shows a side view of a winding unit 1 of a textile machine.
  • the textile machine can be a winding machine or a spinning machine, in particular a ring or air-jet spinning machine.
  • the winding unit 1 winds thread coming from a delivery bobbin or a spinning unit onto a cheese 2.
  • the cheese 2 is held by a bobbin holder 3 and is driven by a drive roller 4.
  • the thread is crossed by a traversing device 5 on the Cross-wound bobbin 2 laid, the speed of the traversing movement being adapted to the speed of rotation of the cross-wound bobbin 2.
  • the bobbin holder 3, the drive roller 4, the traversing device 5 and a first part 6.1 of a suction nozzle 6 form a base unit 7 of the winding station 1.
  • a second part 6.2 of the suction nozzle 6 and a suction mouth 8 form a cover unit 9 of the winding station 1.
  • the cover unit 9 is rotatable about an axis A with respect to the base unit 7 between a working position shown here and a cleaning position.
  • the cover unit 9 can be locked in the working position by means of a locking means 10.
  • the suction nozzle 8 is linearly displaceable by means of a motor 11 so that it can be brought into the vicinity of the surface of the cheese 2. Because only the relatively small suction opening 8 and not the entire suction nozzle 6 has to be moved, the space required for the movement is relatively small and a small motor 11 is also sufficiently powerful.
  • Figure 1b shows a cross section of the winding unit 1 from Figure 1a .
  • the cover unit 9 is again in the working position and the suction mouth 8 is removed from the cross-wound bobbin 2, so that winding operation is possible without hindrance.
  • An air channel 12 runs through both parts 6.1 and 6.2 of the suction nozzle 6.
  • the suction port 8 here closes the upper end of the air channel 12 so that no air is sucked off even when the vacuum is switched on at the suction port 8.
  • An interruption flap 13 is also provided, which is connected to the cover unit 9 via a linkage (not shown here). In the position shown here, the interruption flap 13 allows air to pass unhindered through the air duct 12.
  • FIG. 1c shows the winding unit 1 in the working position when searching for the thread.
  • the suction port 8 is located just above the surface of the cross-wound bobbin 2.
  • the suction port 8 is now connected to the air duct 12 via an air opening 14, so that the negative pressure penetrates to the suction port 8.
  • the cheese 2 is slowly rotated in the opposite direction to the winding operation until the thread end is sucked into the suction mouth 8 and further into the air duct 12 via a suction opening of the suction mouth 8.
  • the thread end found is then fed to further processing by the suction nozzle 6 and / or a thread catcher.
  • This further processing can, for example, be the connection with another thread end or the attachment to a spinning unit.
  • the suction port 8 is then removed again from the cheese 2 so that the winding operation can be continued undisturbed.
  • the winding unit 1 is cleaned, for example, after a predetermined time or when a sensor detects contamination.
  • the winding unit 1 is in the in Figure 1d shown cleaning position brought.
  • the cover unit 9 was rotated about the axis A with respect to the base unit 7. This movement also automatically closed the interruption flap 13, so that negative pressure is not unnecessarily consumed.
  • the suction nozzle 6 is now divided into its two parts 6.1 and 6.2 and is more accessible: it can now also be cleaned from the inside. This makes cleaning both easier and more thorough.
  • FIG 2a shows a winding unit 1 with a suction mouth 15 that can be rotated about an axis B.
  • the cover unit 9 is in the working position and the suction mouth 15 is set to search for thread, so that a suction opening of the suction mouth 15 is located directly above the surface of the cheese 2 .
  • the air opening 14 again establishes the connection between the suction opening 15 and the air duct 12, so that negative pressure reaches the suction opening 15.
  • the cover unit 9 is placed in the in Figure 2b shown cleaning position moved.
  • the cover unit 9 is displaced linearly with respect to the base unit 7 in this exemplary embodiment.
