Definitions

  • the present invention relates to an open-end spinning machine with a plurality of juxtaposed jobs with open-end spinning devices, each having a sliver disintegrating device with a dirt outlet opening.
  • a dirt removal device extending in the machine longitudinal direction is arranged below the dirt outlet openings.
  • a sliver is fed to a sliver breaker before the single fibers enter the spinning rotor.
  • the sliver breaker is open at the bottom. The opening serves as a dirt outlet opening.
  • the dirt removal device can be designed as a conveyor belt running in the machine longitudinal direction, which picks up and removes the dirt particles occurring during the fiber sliver dissolution. The dirt particles fall on the conveyor belt and are transported by this to pneumatic Schmutzabsaug wornen in the field of Maschinenendgestelle.
  • a fiber tuft could form, which could be sucked back into the area of an opening roller of the fiber sliver disassembling device and then significantly disturb the spinning operation, is a brush-like on the conveyor belt Cleaning element arranged, the bristles extend into the region of the dirt outlet opening and thus prevent growth of the tuft.
  • the object is achieved by an open-end spinning machine with a plurality of juxtaposed jobs with open-end spinning devices, each having a sliver opening device with a dirt outlet opening.
  • a dirt removal device extending in the machine longitudinal direction is arranged below the dirt outlet openings and the dirt removal device is designed to convey dirt particles to pneumatic dirt suction devices in the region of machine end racks.
  • at least one intermediate unit is arranged between the work stations, which comprises a further pneumatic dirt suction device, which is designed to suck up dirt particles from the dirt removal device.
  • a further dirt suction device can be installed in a simple manner.
  • the paths which the dirt particles have to be transported to the dirt removal device are shortened, and larger accumulations of dirt particles are avoided.
  • the dirt particles can be safely and quickly removed.
  • the intermediate unit is designed so that it can be mounted instead of a job.
  • This design of the intermediate unit is particularly advantageous since the existing construction of an open-end spinning machine, or its machine frame, does not have to be changed. In addition, already delivered machines can be easily retrofitted.
  • the width of the intermediate unit is less than or equal to the width of a job.
  • These requirements are a minimum requirement for interchangeability with a job. For interchangeability, however, it is best if the width of the intermediate unit and the jobs is the same.
  • An intermediate unit of smaller width than the work stations is preferably accommodated in an intermediate section.
  • the jobs are grouped together. These groups are called sections.
  • the intermediate unit can then be accommodated in its own intermediate section between two sections of workplaces.
  • the advantage of this is that the intermediate section only has to be as wide as the intermediate unit. In this case, one would design the intermediate unit so that it has the smallest possible width so as not to waste any useful length of the machines.
  • An arrangement in an intermediate section makes sense especially when several intermediate units are distributed over the length of the machine, since then the smaller width of the intermediate units is more significant.
  • the interchangeability of the intermediate unit and the workstations is preferably supported by the fact that the intermediate unit and the workstations have corresponding fastening elements for attachment to a machine frame.
  • Such fasteners may for example be hooks which are hooked into a corresponding rail on the machine frame.
  • the further pneumatic Schmutzabsaug driving is connected to a vacuum supply of jobs.
  • no additional vacuum supply for the further pneumatic Schmutzabsaug driving is required.
  • the Fig. 1 shows a front view of some of the series-arranged workstations 20 of an open-end spinning machine 1.
  • open-end spinning machines 1 per side machine often several hundred of these jobs 20 are arranged side by side.
  • the work stations 20 each comprise an open-end spinning device 2. These are known and, for example, in the DE 195 24 837 A1 Open-end spinning devices 2 described have an evacuated rotor housing in which rotates at high speed, a spinning rotor. This in Fig. 1 not shown, open towards the front rotor housing is closed during the spinning operation by a cover element, a so-called pivot cover 3.
  • the swivel cover 3 also has, among other things, a sliver opening device 4.
  • the sliver opening device 4 which decomposes a sliver 9 presented in spinnable individual fibers, has, as usual, a rotating in an opening roller 5 opening roller 6, a feed roller 7 and a feed trough with upstream sliver compressor 8.
  • the opening cylinder 5 of these sliver 4 also have each a dirt outlet opening 10 for discharging the resulting in the sliver dissolution dirt components.
  • a machine-length dirt disposal device 11 is arranged below the dirt outlet openings 10, which has a guided in a channel construction 13 endless Schmutzabtransportband 12.
  • the channel construction 13 has, as usual, an upwardly open Schmutzabtransportkanal 14 and an underlying return channel 15.
  • the endless Schmutzabtransportband 12 is driven changeable via an electric motor (not shown).
  • a cleaning slide 16 is arranged, which during operation is carried along by Schmutzabtransportband 12 via friction.
  • the cleaning carriages prevent the accumulation of dirt particles on the dirt outlet opening 10.
  • the dirt particles emerging from the dirt outlet opening and the particles of dirt dissolved by the cleaning device fall onto the dirt removal belt 12 and are transported away from it in the direction of the machine ends.
  • the open-end spinning machine 1 has at the machine ends not shown Maschinenendgestelle that contain in a known manner pneumatic Schmutzabsaug Rheinen that suck the delivered on the Schmutzabtransportband 12 dirt particles.
  • an intermediate unit 17 is arranged between the work stations 20, which includes a further pneumatic dirt suction 18. There may be arranged more intermediate units 17 distributed over the machine length.
  • the dirt suction device 18 is directed to the dirt removal belt 12 and sucks on the Schmutzabtransportband 12 passing dirt particles.
  • the intermediate unit 17 is designed so that it can be mounted instead of a workstation 20.
  • the intermediate unit 17 has the same width as the workstations 20.
  • the attachment of the intermediate unit 17 to the machine frame takes place in the same way as the fastening of the workstations.
  • the dirt suction device 18 is connected to the vacuum supply of the jobs.
  • the undersupply of the dirt suction device 18 can be effected in particular via the vacuum supply of a suction nozzle, not shown.
  • the pivotable suction nozzle is used at the workstations to capture after a thread interruption accumulated on the package reel thread and to transport for re-spinning to the open-end spinning device 2.
