Definitions

  • the present invention relates to a suction device for a spinning machine with at least one arranged at one end of the suction suction for sucking a fiber structure, arranged at the other end connection opening for connection to a vacuum device and a pipe arranged between the two ends pipe section, wherein at the pipe section a the Cross-section of the pipe section magnifying dirt collecting space is arranged for accumulating dirt deposits and an area of the pipe section and / or the dust collecting space as - between at least one working position and at least one cleaning position - movable element is formed.
  • the invention further relates to a spinning machine with a plurality of spinning stations, each having a drafting and a twist generating device and with a suction, and a method for sucking loose fibers, dirt and fiber structures with such a suction device.
  • Extraction devices for spinning machines for sucking off a fiber structure, in particular after a yarn break are well known.
  • these suction devices also absorb some of the remaining loose fibers and dirt.
  • sticky parts of the dirt such as honeydew, avivage, oils and water, settle over time on the inner walls of the suction device and then have to be laboriously removed, usually by a mechanical cleaning process.
  • Even with a curved suction tube, as for example in the Scriptures DE 197 33 614 A1 is described, this problem is given. The curvature of the suction tube makes it even more difficult to clean the soiled areas.
  • a very elaborate suction device is also in the Scriptures CH 496 824 disclosed.
  • the sieve is cleaned by a stream of air which, from time to time, flows through a purge flap into the suction tube.
  • the object of the present invention is thus to provide a method and a suction device which are improved in their handling with respect to dirt.
  • the object is achieved by a suction device, a spinning machine with an extraction system and a method for suction with a suction device with the features of the independent claims.
  • Proposed is a suction device for a spinning machine with at least one suction opening, a connection opening and a pipe section.
  • the suction opening which is arranged at one end of the suction device, is designed to suck off a fiber structure.
  • this fiber structure is a thread following a yarn breakage is sucked off.
  • loose fibers and dirt which are located in the thread running area, sucked with.
  • connection opening which is arranged at the other end of the suction device, is designed for connection to a vacuum device.
  • This vacuum device produces the necessary vacuum for suction, usually for a variety of suction devices.
  • the pipe section is arranged, which connects the suction opening with the connection opening. It is also possible that the pipe section connects a connection opening with a plurality of suction openings. In this case, the pipe section has corresponding branches.
  • a dirt collecting space for accumulating dirt deposits is also arranged.
  • This dirt collecting space is designed so that it increases the cross section of the pipe section. Due to the enlarged cross-section of the pipe section in the region of the dust collecting space areas with a reduced suction air flow. In these areas, the heavier dirt increasingly settles, while the lighter fiber parts continue to follow the stronger Saugluftströmung. As a result, the area where the dirt collects is largely separated from the area where most of the fibers move, and thus the collected debris does not affect the fibers. Likewise, the dirt collected in the debris trap does not affect the suction air flow. Depending on the size of the dirt collection room, a considerable amount of dirt may be collected before it is necessary to remove dirt from the extraction system.
  • a region of the pipe section and / or the dirt collecting space is designed as a movable element.
  • This moving element is movable between at least one working position and at least one cleaning position.
  • an opening in the dirt collecting space is released in the cleaning position, by means of which the dirt collecting space can be cleaned.
  • the cleaning can be done with negative pressure, with compressed air, or mechanically, for example with brushes. It can be carried out by a robot or a traveling cleaner or the operating personnel.
  • the pipe section has a region in which changes the axial direction of the pipe, hereinafter referred to as tube curvature
  • the dirt trap is in this area or directly adjacent to this area.
  • the pollution is particularly strong: the suction air flow is usually not strong enough to move the heavier dirt particles along the pipe bend and so they fly due to their inertia to the outside of the pipe bend. At this point, so a particularly heavy pollution occurs.
  • the dirt catchment space in this area, in particular on the outside of the pipe bend, arranged then the dirt can collect here and let the Saugluftströmung and longer fibers pass unimpaired.
  • the axial direction of the tube at the suction opening is different from the axial direction of the tube at the connection opening.
  • the suction opening can be easily positioned in the correct position and at the correct angle.
  • Two advantageous embodiments of the movable element are a flap and a slider: these are both easy to manufacture and robust in operation.
  • the movable element is removable. So the movable element can be cleaned separately. In addition, it is easily possible to replace the movable element, for example, because it is defective or worn. Likewise, the movable element can be exchanged for another movable element having, for example, a larger or smaller suction opening.
  • a locking device which locks the movable element in the at least one working position and / or the at least one cleaning position.
  • This locking device can be formed for example by elevations and with these cooperating depressions in the movable element or the immovable areas of the pipe section or the dirt collecting space, which fit in the individual working and / or cleaning positions to each other and be moved in between with force.
  • locking devices for example with locking levers and matching notches conceivable.
  • the locking in the working position or the working positions is especially important so that a trouble-free operation of the suction device can be ensured without the moving element of its own removed from the desired position. But even in the cleaning position, it may be appropriate to lock the movable element, so as not to hinder the cleaning.
  • one side of the movable element forms part of the suction opening and, depending on the working position in which the movable element is located, the suction opening assumes different sizes.
  • the differently sized suction openings can be used, for example, for different thicknesses of yarn: small suction openings for fine yarns, large extraction openings for coarse yarns.
  • the cleaning position is formed so that the movable element is located in a yarn running area of the spinning machine when it is in the cleaning position. This prevents it from being spun again as long as the moving element is still in the cleaning position.
  • a sealant in particular sponge rubber, be attached to at least one of the surfaces, or the surfaces may be labyrinth-like interlocked with each other to increase the air-tightness.
  • the movable element is a flap.
  • one side of the flap forms one side of the suction opening.
  • the flap forms a wall region of the dirt collecting chamber and of the tube section, which is essentially straight and has an expansion only in the region of the flap. If the flap is moved into the cleaning position, it releases a large opening to the dirt collecting area.
  • the pipe section is substantially un-curved when the flap is in the cleaning position, the dirt collecting chamber and the pipe section can be easily cleaned, for example, with a straight cleaning item.
  • the flap protrudes in the cleaning position in the yarn path area and thus prevents spun while it is in this position.
  • the pipe section and / or the connection opening have a closing means and a mechanical and / or electro-mechanical coupling between the movable element and the closing means.
  • This coupling is designed to be that Closing means moves to a position in which it closes the suction device when the movable member is in the cleaning position.
  • a spinning machine with a plurality of spinning stations and with an extraction system.
  • Each spinning station has a drafting system and a swirl generating device.
  • the extraction system comprises at least one suction device described above.
  • the spinning stations and the suction devices are designed so that each spinning station is associated with a suction opening. So can be sucked off after a yarn breakage fiber structure and in spinning operation loose fibers and dirt. Thanks to the special design of the extraction system handling is simplified with regard to the accumulated dirt.
  • the dirt collecting space is regularly and / or if necessary cleaned of dirt. It is particularly advantageous in this case if the extraction system has a movable element which, in a specific position, in particular a cleaning position, releases an opening through which the dirt collecting space can be cleaned. This simplifies and shortens the cleaning effort considerably.
  • FIG. 1 a shows a longitudinal section of a suction device 1 and a part of a vacuum device 2, to which the suction device 1 is connected.
  • a suction air flow 3 which can carry loose fibers, dirt and fiber structure (not shown here) with it, enters the suction device 1 through a suction opening 4.
  • the suction air flow 3 then follows a pipe section 5 and passes through a connection opening 6 in the part of the vacuum device 2 continue.
  • a dirt collecting space 7 is provided, in which the suction air flow 3 is significantly weaker.
  • dirt 8 collects in the dirt collecting chamber 7 and clogs no other areas of the pipe section 5.
  • One side of the dirt collecting chamber is designed as a movable slide 9. In this figure, the slider 9 is in a working position.
  • the suction device 1 When a certain amount of dirt 8 has collected in the dirt collecting chamber 7, the suction device 1 must be cleaned.
  • the slider 9 in an in Figure 1 b moved cleaning position shown and releases an opening 10 in the dirt trap 7. Through this opening 10, a part of the dirt 8 falls out of the dust collecting chamber 7.
  • the opening 10 also makes the dirt-collecting chamber 7 accessible to a cleaning device, for example a suction nozzle, a high-pressure nozzle or a mechanical cleaning device such as a brush. With the help of this cleaning device, the dirt collecting chamber 7 can be completely freed from the dirt 8.
  • FIG. 2 illustrated alternative embodiments are for features compared to in FIGS. 1a and 1b
  • suction device 1 has a slide 9 with a detent 11.
  • This catch 11 cooperates with a locking lever 12, so that the locking lever 12 engages in the working position in the catch 11 and locks the slider 9 in the working position. This ensures that the slide 9 is not accidentally or accidentally moved and seals in the working position with the other parts of the suction device 1.
  • the pipe section 5 now has an area in which the axial direction of the pipe section 5 changes and the dirt collecting chamber 7 is arranged in this area. Due to the inertia of the dirt particles, this results in a dirt trajectory 13, which conveys the dirt particles out of the region of the largest suction air flow 3 and into the dirt collecting chamber 7.
  • a flap 14 is provided, whose one edge forms one side of the suction opening 4.
  • FIG. 3b The function of the flap 14 is in FIG. 3b shown.
  • two further working positions 15b, 15c and a cleaning position 16 are sketched.
  • different working positions 15 different sized suction 4 are thus achieved.
  • lateral wings 17 serve on the flap 14, which are shown for clarity only in the cleaning position 16, the airtight seal with the immovable parts of the pipe section 5 and the dust collecting chamber 7.
  • the flap 14 then releases a large opening , so that the dirt collecting chamber 7 can be easily cleaned of dirt 8.
  • Figure 3c shows an external view of the suction device 1.
  • On the side wings 17 are two round elevations 18a, 18b, such as knobs, attached, which act together with a corresponding recess (not shown here) in the pipe section 5 as a locking device for two working positions.
  • a thread running area 19 of the spinning machine is also outlined.
  • the flap 14 projects into the thread running area 19 and thus makes spinning or piecing impossible.
  • FIG. 4a now shows a cross section of the pipe section 5 with flap 14.
  • the flap 14 closes with the pipe section. 5 at a contact point 20 from accurate fit, so that no air can escape here.
  • suction device 1 is a removable suction nozzle 23 is provided.
  • This suction nozzle 23 can be fixed with a locking lever 24 in a working position fixed to the stationary part of the suction device 1.
  • the suction nozzle 23 and the stationary part of the suction device 1 close off accurately.
  • Other sealing methods such as those in the Figures 4b and 4c presented, but are also conceivable.
  • the dirt collecting chamber 7 is assigned to a part of the suction nozzle 23 and the other part to the stationary part of the suction device 1.
  • the suction nozzle 23 is separated from the stationary part of the suction device 1. This allows free access to the dust collecting space 7, which can then be easily removed from the dirt 8.
  • connection coupling 25 On the side of the connection opening 6, the pipe section 5 has a connection coupling 25, so that the suction device 1 can be connected quickly and precisely to a vacuum device.
  • the suction device 1 has a retaining clip 26, with which it can be firmly attached to, for example, a housing part of the spinning machine.
