Definitions

  • the invention relates to a device for resolving Fiber tapes according to the preamble of claim 1.
  • a sliver is made using a Opening roller with combing elements on its circumference, for example Saw teeth or needles, dissolved up to the single fiber.
  • the Sliver is the opening roller of a feed device fed evenly.
  • a known feeding device has a corrugated roller and a feed table or a Feed tray, which both work together and a nip form.
  • the Opening roller is usually with a Circumferential speed driven from 20 to 30 m / sec. To one uneven resolution of the sliver and an increased Removal of not or only partially resolved Avoiding tufts of fiber from the sliver will be high Circumferential speeds of the opening roller selected.
  • the combing elements are on the circumference of the opening roller arranged that their to the axis of rotation of the opening roller ideally equally spaced tips on an imaginary helical curve, comparable to a catchy one or multi-start thread.
  • the combing elements or their Chest surfaces are usually at an angle of 15 ° to 20 ° inclined in the running direction of the opening roller in order to pull in of the fibers in the through the helical course of the tips to support alleys formed between the combing elements.
  • Such a so-called positive breast angle Combing elements make it difficult to detach the fibers from the Opening roller for further transport in the air stream.
  • the opening roller is the transport air speed in each case higher than the peripheral speed of the opening roller set.
  • the fibers become a twist like that Spinning rotor or the friction rollers and promoted there Thread thickness collected, drawn off and turned.
  • An open-end spinning device designed as a friction spinning device with two friction rollers, for example described in DE 195 26 845 A1.
  • DE 31 27 415 A1 discloses a feed and Dissolver by using as a rack trained fixed support elements in the sliver Hold the area of the opening roller assembly and that Moving the fiber beard in the axial direction of the Prevent opening roller.
  • the prongs of a support element can be in between intervene with the existing furniture lanes.
  • the use of the support element as a combing element requires parallel rows of teeth on the circumference of the opening roller, like them 8 of DE 31 27 415 A1 are shown. parallel However, rows of teeth are unsuitable for effective combing out. Because of this, the device could be used in the last not enforce two decades.
  • the invention is based, known Devices for dissolving fiber tapes for feeding to improve an OE spinning device.
  • the inventive design of the device leads to a particularly intense influence and interaction of the Comb elements of the opening roller and the support roller the fiber material.
  • the fiber material is better in one hand the effective area of the combing elements retracted and better in the Alleys pressed between the combing elements and the effect of Comb elements more exposed, but also that Removing the fibers from the opening roller by the friction supports the additional combing elements. Dodging the Fibrous beard in front of the combing elements is prevented and the number the one that engages in the fiber material at the same time Combing elements and their effect on the fiber material advantageously increased. The dissolution of the fiber material will sustainably improved.
  • the arrangement of the combing elements on the Opening roller in the form of a catchy or multi-course Thread leads through the axial thrust that the threads on the fibers, also to support the Removing the fibers from the opening roller. A sure one Removing the fibers from the opening roller. A sure one Compliance with the required angular position of the Support roller compared to the opening roller without mutual contact is guaranteed. In particular a touch while optimizing the effect of Combing elements avoided when the engagement of the combing elements Support roller each in the middle of the alley-shaped trained space between the coils of the Combing elements of the opening roller takes place. It can continue to inexpensive large-scale opening rollers in normal design can be used.
  • the combing elements are preferably designed such that they a breast angle ⁇ in the range from + 5 ° to -10 ° exhibit.
  • This training makes it easier to remove the Fibers from the opening roller considerably and enables the to support the removal of the fibers from the Opener roller used low speed air flow to let flow.
  • the one for generating the airflow required pressure difference can be a lot lower value than usual.
  • the negative pressure is one of the generation of the with that of the Opening roller of detached fibers from the air flow serving vacuum source below 10 mbar, in particular 3 to 5 mbar. So clear compared to a negative pressure of 20 reduced to 25 mbar with conventional dissolving devices Negative pressure for the generation of the transport air flow leads to considerable savings in operating costs with the large number of spinning positions of a spinning machine. This saving can be both with friction spinning machines and with Achieve rotor spinning machines.
  • the peripheral speed is preferably Opening roller less than 15 m / s, preferably 4 to 10 m / s. This enables a particularly gentle dissolving process and reduces fiber damage and wear of the Combing elements. The formation of fine dust can also be done this way be reduced. In particular, however, the solve Fibers, not all of which are on the short path anyway between the fiber beard and that leading into the fiber guide channel Opening in the roller cover to the peripheral speed the opening roller can be accelerated with a clear slower speed than usual from the opening roller.
  • the reduced peripheral speed of the opening roller, a short residence time of the fibers on the circumference of the opening roller as well as additionally interacting with a degraded one Speed of the air flow between the opening roller and the OE spinning device leads to a desirably low one
  • the fibers meet there a thread that usually forms with a Speed of only 3 to 5 m / sec moves and is subtracted.
  • the support roller is over one Gear drive coupled to the opening roller and that Gear ratio between the opening roller and the Backup roller is 1: 2.
  • the drive ratio is based on the design of the drive easily and consistently adhered to and thus a Non-contact engagement of the combing elements guaranteed.
  • the gears belonging to the rollers can be the same Obtain diameter as the respective roller. Such Execution also facilitates the installation and removal of the two Rollers.
  • the arrangement of the combing elements is advantageous formed spiral in its course around the circumference of the roller interrupted by comb-free sections.
  • the support roller is mounted in a holder, the at the same time carries the sliver feed device.
  • Swiveling the bracket together with the support roller by means of the combing elements of the opening roller and the support roller disengage and both rollers be removed by pulling it out axially.
  • the one and Expansion of the opening roller and the support roller is on this way simplified and facilitated.
  • the arrangement of the Sliver feeder on the bracket and storage the support roller in this holder enables one particularly compact design and easy access to the Components of the resolver.
  • the opening roller and the support roller advantageously have Markers for positioning on. Leave the markings generate easily and with little effort, for example by Paint application or by scratching or wrapping, and allow as an assembly aid when reinstalling the two rollers fast and accurate reproduction of the required Angular position or the axial position.
