Definitions

  • the invention relates to an open-end spinning machine with a plurality of workstations arranged next to one another, which have a spinning rotor supported on a support disk bearing, rotating in a vacuum-loaded rotor housing, and a fiber sliver opening device with a release roller rotating in a swivel housing, the rotor housing facing forward through a swiveling roof arranged fiber channel plate is closable and a dirt disposal device is attached below a dirt outlet opening arranged in the swivel housing.
  • Open-end spinning machines of this type are known and are described in detail, for example, in the "AUTOCORO" manual from the company Schlafhorst.
  • a machine-long, all-round dirt removal belt is arranged below the sliver opening devices of the spinning units of the rotor spinning machines, which picks up the dirt escaping at the dirt separation channel of the swivel housing and transports it to a dirt transfer point on the machine end, where the belts are emptied.
  • DE 21 12 170 A1 describes, for example, a rotor spinning device in which a sliver fed between the feed roller and a feed trough is broken down into individual fibers by a disintegration roller. In this process dirt particles and fibers are also largely separated.
  • the opening roller transports both components via a fiber guide surface into the area of a dirt outlet opening. During this transport, both the fibers and the dirt particles are accelerated in the shortest possible time to approximately the peripheral speed of the opening roller by the opening roller or by an air flow rotating with the opening roller.
  • the mass particles, as fibers and dirt particles endeavor to leave the circular path tangentially as soon as the inevitable mechanical guidance is interrupted, as is done in the area of the dirt outlet opening of the opening roller housing.
  • a dirt collecting space is arranged directly below the dirt outlet opening and is connected to a central suction device of the spinning machine via a connecting channel.
  • the dirt outlet opening is also designed here as a suction opening for an air flow entering the opening roller housing.
  • This air flow directed onto the opening roller holds the fibers, which have a relatively large specific surface area in relation to their small mass, as it were, as a pneumatic guide, on the opening roller.
  • the dirt particles which, due to their size and mass, have a significantly higher kinetic energy, overcome this air flow and are thrown away tangentially.
  • a dirt chamber is arranged directly after the dirt outlet opening of the opening roller housing and is divided into a dirt separation zone and a dirt removal zone by an air guide wall which is arranged at a short distance from the dirt outlet opening.
  • an OE rotor spinning device with a dirt chamber arranged below the opening roller which has two separate air flow systems, each with its own suction openings.
  • An air flow system effective in the bottom area of the dirt chamber disposes of the dirt particles combed out by the opening roller, while a second air flow system having an opposite effect opens into a suction flow circulating with the opening roller.
  • the special arrangement of the intake opening leads to a more or less clear separation of the two flow systems.
  • the post-published DE 43 34 483 describes an open-end spinning device which has an opening roller housing which is arranged in the cover element of the spinning unit and which can be pivoted with the cover element.
  • the opening roller housing has a dirt outlet opening, to which a pneumatically actuated dirt-receiving element is assigned at a distance from one another.
  • a free space in connection with the ambient air is provided between the dirt outlet opening and the dirt receiving element.
  • the dirt-receiving element is detachably fastened to the cover element mounted on a pivot axis and, when the spinning device is opened, is tilted downward about the pivot axis together with the cover element.
  • the dirt separation on the opening roller housing of a rotor spinning machine is an important element with regard to a perfect processing of fibrous materials.
  • the technology of the dirt separation devices seems relatively simple, these devices are very difficult devices that are sensitive to changes. Even small modifications in the area of the dirt outlet openings can permanently change the flow conditions and thus have a considerable influence on the achievable spinning results.
  • the invention has for its object to provide a pneumatic dirt disposal device that can be used universally.
  • the inventive design of the pneumatic dirt suction device has the advantage, among other things, that subsequent installation of the device is also possible on those rotor spinning machines which were originally designed for mechanical dirt disposal. Design changes in the area of the spinning stations are not necessary for this.
  • the new dirt suction device makes it possible to equip a rotor spinning machine with either a mechanical or a pneumatic dirt disposal device, it being possible for the choice made to be corrected at a later point in time.
  • An existing mechanical dirt disposal system can, for example, be carried out without problems the pneumatic dirt suction device according to the invention can be replaced.
  • the special design of the dirt suction device according to the invention and the way in which it is attached to the spinning units ensure that all the functions of the spinning units, in particular the opening of the top for cleaning the spinning station, are in no way impaired.
  • the pneumatic dirt suction device arranged below the swivel housing of the rotor spinning units essentially consists of a dirt hopper, which is connected via a rear suction nozzle directly or indirectly to a machine-length dirt channel that is pressurized with vacuum.
  • the dirt holding funnel has a transverse connecting strip with bores, via which the holding funnel can be fixed to a support rail arranged on the spinning units. If necessary, the guide duct parts of a mechanical dirt disposal device are also fastened to these support rails.
  • the dirt holding funnel is designed as an asymmetrical injection molded part, preferably made of plastic.
  • asymmetrical injection molded part preferably made of plastic.
  • Such a component can on the one hand be easily adapted to the structural conditions of existing OE spinning machines, and on the other hand such injection molded parts, which is also advantageous given the large number of spinning stations of such machines, can be manufactured inexpensively.
  • the rear suction connection of the dirt collecting funnel is guided to the rear just below the support rail of the rotor spinning units and connected to the dirt duct under pressure via a line, for example a spiral hose, etc.
  • the dirt channel is designed as a machine-long suction traverse, which is arranged in the machine longitudinal axis of the spinning machine, for example below a channel for the energy supply.
  • the dirt channel is connected on the machine end to a spinning device's own suction device, which has, among other things, a filter device and a vacuum source.
  • FIG. 1 shows an intermediate unit 2 of an open-end rotor spinning machine 1.
  • Such rotor spinning machines each have a drive unit (not shown) and an end unit (also not shown) and up to twelve of the intermediate units 2 shown.
  • each of these intermediate units 2 has twenty-four workplaces 3 (twelve on each side).
  • the work stations 3 each have an OE rotor spinning unit 4 and a winding device 5.
  • each intermediate unit 2 has a suction channel 6, via which, for example, the rotor housing 20 of the rotor spinning unit 4 is subjected to a vacuum.
  • An electronics duct 7 and a dirt duct 8 are arranged below the suction duct 6.
  • the dirt channel 8, which is designed as a machine-long suction traverse, is connected to a spinning suction device 9, which has, among other things, a vacuum source 10, a filter element 11 and a dirt disposal 12.
  • the pneumatic dirt suction devices 13 of the rotor spinning units 4 are connected to the dirt channel 8.
  • the rotor spinning units 4 are shown in more detail in FIGS. 2 and 3.
  • a spinning rotor 17 is mounted on a support disk bearing 15 with its rotor shaft 16.
  • An axial bearing 18 is also provided to absorb axial forces.
  • the spinning rotor 17, which is driven by a tangential belt 19, rotates at high speed in the rotor housing 20, which is connected to the suction channel 6 via a connecting line 21.
  • the rotor housing 20 is closed at the front by a fiber channel plate 22 which is fastened to a pivotable top 23.
  • a thread draw-off nozzle 25 is arranged in the center of an extension 24 of the fiber channel plate 22.
  • a two-part fiber guide channel 26 opens into the extension 24, which connects the sliver opening device 27 to the interior of the spinning rotor 17.
  • the top 23 can be pivoted about the pivot axis 29 in the direction S after loosening a bolt 28 and thereby tilted into a first cleaning position or a second maintenance position.
  • the sliver opening device 27 consists essentially of a opening roller 31 rotating in a swivel housing 30, a sliver feed cylinder 32 and a Sliver feed trough 33.
  • the sliver 34 is fed to the sliver opening device 27 via a compressor 35.
  • the swivel housing 30 surrounding the opening roller 31 is partially open, that is to say it has a dirt outlet opening 36 directed downward.
  • a pneumatic dirt suction device 13 is arranged at a distance below the swivel housing 30 and can be fixed on a support rail 37 of the rotor spinning unit 4.
  • the dirt suction device 13 has an asymmetrically shaped dirt holding funnel 38, which is connected via a rear suction nozzle 39 to the dirt channel 8 of the rotor spinning machine 1 which is under pressure.
  • the dirt holding funnel 38 is constructed asymmetrically both in the area of its receptacle and in its rear connection area.
  • the dirt hopper also has a terminal block 40 with mounting holes 41 in the upper region.
  • the dirt holding funnel 38 can be fixed on the support rail 37 of the rotor spinning units 4 via the fastening bores 41.
