Definitions

  • the invention relates to a method for cleaning air nozzles and reeds in air jet weaving machines, in which air nozzles can be connected to a compressed air source via controlled valves in such a way that the weft is shot into a guide channel in the blade and transported to the opposite fabric edge by the air streams generated.
  • the invention further relates to a nozzle arrangement for performing such a method.
  • the weft is transported through the compartment with the aid of an air stream.
  • the sheet is provided with a guide channel.
  • the shot is injected into the guide channel through a main nozzle and then by air currents emitted by Relay nozzles are generated, transported to the opposite tissue edge.
  • the relay nozzles are supplied with compressed air one after the other via controlled valves in the form of solenoid valves.
  • Such air jet weaving machines are described, for example, in EP-A-0 114 047 and in a company publication "PAT W Airtronic" from June 1986 by PICANOL NV, Polenlaan 3-7, B-89oo Ieper, Belgium.
  • the invention has for its object to improve and facilitate the cleaning of the air nozzles and the reed and to avoid the risk of damage to machine parts during cleaning.
  • this object is achieved in that cleaning fluid is passed through the air nozzles at intervals at intervals for cleaning purposes.
  • a nozzle arrangement for performing this method is the subject of claim 2.
  • a cleaning liquid is pressed through the air nozzles for cleaning purposes while the machine is running.
  • This cleaning liquid flushes dust and other particles out of the air nozzles and the guide channel.
  • the air nozzles and the reed are "cleaned" by the back and forth warp threads, i.e. the cleaning liquid and the flushed out particles are wiped off.
  • the air nozzles and the guide channel then work properly again. It is not necessary to use a brush to approach the individual air nozzles.
  • the figure schematically shows an arrangement of air nozzles of an air nozzle weaving machine with the controlling solenoid valves and a cleaning device for the air nozzles and the reed.
  • a number of solenoid valves is designated.
  • the solenoid valves are activated in succession in a known manner.
  • Each solenoid valve 1o to 24 controls the supply of compressed air from compressed air connections 26 to 38 to several air nozzles arranged in a row along a guide channel 52.
  • the solenoid valve 10 is assigned three air nozzles 40, 42, and 44.
  • Each of the solenoid valves 10 to 24 is connected to a compressed air source via the associated compressed air connection 26 to 38.
  • a connecting duct 46 branches off between the air nozzles 40, 42 and 44 and the solenoid valve 10.
  • a check valve 48 is located in the connection channel 46. The check valve 48 opens in the direction of the air nozzles 40, 42, 44.
  • a source of cleaning fluid can be connected to the connection channel 46 via a connection device 50.
  • This source of cleaning fluid can be a container filled with cleaning fluid with a hand pump.
  • the hand pump gives a surge of cleaning fluid of about 5 cm3 to the connection channel 46.
  • the check valve 48 is blocked for the compressed air.
  • the cleaning fluid flows through the air nozzles 40, 42, 44 and the guide channel and takes entrained particles there. These particles are flushed into the guide channel to the outside of the air nozzles 40, 42, 44.
  • the cleaning liquid loosens the dirt in the guide channel and on the reed and strips it from the warp threads moving up and down
