Definitions

  • the invention relates to an open-end spinning machine with a Dirt disposal device according to the preamble of Claim 1.
  • Such waste disposal facilities are state of the art Technology and for example in DE-PS 23 56 180, the DE-AS 26 34 770 or DE-OS 26 58 752 described.
  • DE-PS 23 56 180 discloses rotor spinning devices an OE spinning machine with one below the Dirt discharge opening of the open-end spinning units arranged, running in the machine longitudinal direction Conveyor belt, which occurs when the sliver dissolves Pick up and remove impurities.
  • the bristles extend into the area of the dirt outlet opening.
  • the endless conveyor belt is deflected in this known dirt disposal device in the area of the machine ends so that it runs back on the opposite side of the machine and thereby takes away the impurities accumulating on this machine side.
  • the cleaning element is fixed on the conveyor belt.
  • a similar waste disposal facility for Open-end spinning machines is also in DE-OS 26 58 752 described.
  • Transport means for cleaning elements a tangential belt provided, which at the same time as dirt removal means serves.
  • This preferably iridescent tangential belt carries several arranged in a row to form a group summarized, differently designed cleaning elements.
  • the cleaning elements are in holders that are firmly attached to the Tangential straps are arranged, detachable and interchangeable fixed and are during the course of the tangential belt the contaminated components of the spinning units delivered.
  • a dirt disposal device for open-end spinning machines is also described in DE-AS 26 34 770, in which a dirt removal belt is arranged below the dirt outlet openings of the sliver opening devices.
  • the dirt removal belt is arranged along the top of an air duct that has a continuous slot.
  • the dirt removal belt has an opening that forms a connection between the air duct and the dirt outlet openings of the individual sliver opening devices.
  • a dirt scraper is also arranged in the area of this opening via a holder.
  • the Dirt separating openings as well as coarse dirt components also fine dirt particles and fiber fly excreted. While the coarse dirt particles as well as part of the fine dirt particles and the fiber fly over the along the Air duct movable dirt conveyor belt immediately disposed of the remaining fine dirt particles are stored or the fiber flight initially in the area of Dirt outlet openings of the sliver opening devices and are removed from there by the scraper.
  • the scraper is firmly in the area of the aforementioned opening arranged the dirt removal belt and is with the Conveyor belt moved along the air duct. That means the Scraper enters the area simultaneously with the opening a spinning station where he mechanically fine Debris and the flight from the guardrails of the Detaching sliver. The detached Dirt particles are then through the opening in the Extracted air duct.
  • a Dirt disposal device has the advantage, among other things on that by the frictional and thus accumulative Fixing the cleaning sled on the Dirt removal belt ensures that even if the path of the cleaning carriage, for example, through the open swivel cover of an open-end spinning device is blocked, neither the regular removal of dirt is impaired, damage to the cleaning sled or fear on the spinning device.
  • the frictional, accumulative determination of the Cleaning sled makes it possible to do that Dirt removal belt without considering possible Sled blockages in pre-definable time intervals change. Any additional sensors to detect the The position of the cleaning carriage is not necessary.
  • the cleaning sled runs at the end of each run automatically against one in the area of the machine end frame arranged stop and remains there until the change Direction of transport of the dirt conveyor belt. In this way always poses with every change of transport direction automatically a synchronous run of the cleaning sled of the two Machine sides.
  • the cleaning carriage rests freely on the dirt removal belt with a stable support foot.
  • An elastic cleaning lip is attached to the support foot, which extends into the area of the components of the OE spinning devices that are at risk of contamination.
  • the T-shaped described in claim 3 Training the support foot provides a very stable and simple construction.
  • the support foot of the Cleaning carriage as described in claim 4, a portal-like through opening. Through this portal-like The dirt can also be removed through the passage opening when the cleaning sled, as above indicated, for example by an opened Swing lid is blocked.
  • the cleaning lip is adapted with its outer contour to the shape of the components of the sliver opening devices to be cleaned.
  • the cleaning lip preferably has, as described in claim 5, several differently shaped cleaning fingers.
  • the individual cleaning fingers can, depending on the design of the sliver opening devices to be cleaned, differ in terms of their length, their shape or their material. This means that by appropriately designing the cleaning fingers, reliable cleaning of the critical areas of the open-end spinning devices is possible in an economical manner.
  • a starting device is arranged in the area of the dirt removal belts, which makes it easy to lift off the cleaning carriage which is frictionally mounted on the dirt removal belt (claim 6).
  • a start-up device By using such a start-up device, on the one hand the wear both on the dirt removal belt and on the cleaning carriage can be significantly reduced, since the cleaning carriage is lifted off the dirt conveyor belt when it is not required.
  • the cleaning carriage provided in a parking position by the starting device can be used at any time if the degree of soiling of the open-end spinning devices of the relevant machine side requires this.
  • the start-up device is mounted in the end region of the dirt removal belt, preferably on the side opposite a cleaning and suction device of the dirt removal belt (claim 7).
  • the space available in this machine area enables both a relatively simple and uncomplicated installation of a start-up device, as well as parking the cleaning sled lifted off the dirt conveyor belt, without any impairment or hindrance to the spinning process of the open-end spinning machine.
  • the starting device has vertically displaceable cleaning slide receiving element, with an approximately parallel to the dirt conveyor belt the cleaning sled in the area its passage opening and, as in claim 9 set out, by means of a defined actable Thrust piston gear, from a receiving or transfer position can move into a parking position in which the Cleaning sled is free from the dirt conveyor belt.
  • Figure 1 shows a front view of some of the in series arranged open-end spinning devices 2 one Open-end rotor spinning machine 1.
  • Open-end rotor spinning machine 1 As is known, in modern OE rotor spinning machines on each machine side are often far above one hundred of these open-end spinning devices side by side arranged.
  • the sliver opening device 4 which breaks down a sliver 9 provided into spinnable individual fibers, has, as usual, an opening roller 6 rotating in an opening roller housing 5, a feed roller 7 and a feed trough with an upstream sliver compressor 8.
  • the opening roller housings 5 of these sliver opening devices also each have a dirt outlet opening 10 for removing the dirt constituents that arise during the sliver opening.
  • FIG. 2 is below the Dirt outlet openings 10 a machine length Dirt disposal device 11, the one in a Channel construction 13 guided endless dirt conveyor belt 12 has arranged.
  • the channel construction 13 has as usual, an open top Dirt removal channel 14 and an underlying one Return duct 15.
