Definitions

  • the invention relates to a method for cooling a rapier drive and a weaving machine with a coolable rapier drive.
  • Various types of training are known for the grippers and their support members, as well as for their drive.
  • a known type uses long, rigid rods, at one end of which the gripper is arranged for gripping and transferring the weft thread.
  • the known rod-like support members are relatively stiff and low in mass.
  • Such support members are made of fiber-reinforced plastic and have a U-shaped profile cross-section with an integrated rack-like toothing, with which at least one drive pinion is meshingly engaged with an alternating direction of rotation.
  • Other support members consist of flexible bands, at one end of which a gripper is seated, while the other end is connected to a drive wheel.
  • the belts must have a certain stiffness and at the same time be flexible enough to be wound up and unwound on the drive advice, which is driven with an alternating direction of rotation.
  • All carrier elements connected to drive wheels and corresponding guides are subject to certain limits with regard to the weft insertion rate, in particular because of the frictional heat generated in the drive and guide area of the carrier elements.
  • the friction leads to rapid wear of the elements involved in the drive and in guiding the support members.
  • the operating time of the drive and management elements is sustained the fiber flight arising in the weaving process and entering the area of the rapier drive and the area of the guide members is impaired.
  • the invention is therefore based on the object, firstly to dissipate the frictional heat generated in the area of the drive and the guide of the carrier members and to achieve a targeted cooling of these members, and secondly to keep the fiber fly arising during the weaving process largely away from the drive, carrier and guide members.
  • the gripper drive which is formed from a rack-like support member and from at least one pinion driven with an alternating direction of rotation, and the drive being surrounded by a housing shielding the fiber flight, is supplied with or removed from an air-conditioned medium under pressure.
  • the housing is connected to a pressure line, via which the conditioned medium is supplied or withdrawn from the housing under pressure. If the medium is supplied, it flows around the area of the gripper drive and reaches the guide rollers, which are also cooled, via slot-like openings which exist between the housing wall surrounding the carrier element on the one hand and the guide rollers or the bearing plate and the housing wall on the other hand.
  • the pressure line is connected to a vacuum source, which creates a negative pressure in the housing.
  • air is drawn into the housing, for example from the atmosphere, via the slot-like openings.
  • Such a solution can be used, for example, in the production of technical fabrics, from monofilaments in warp and weft.
  • the compressed air leads to a significant drop in temperature Gripper drive and on the guides of the carrier member.
  • the air flow exiting the slot-like openings with overpressure ensures that fiber fly cannot settle in the area of the gripper drive and, on the other hand, during vacuum operation, the fiber fly is removed from the suction air flow.
  • the solution according to the invention increases the wear resistance of the organs involved in the weft insertion, in particular the carrier organs, the drive pinion and the guide rollers. Due to the cooling of the drive, support and guiding elements from the air-conditioned medium, a performance increase of the weaving machine of about 10% is achieved and finally the medium emerging from the outflow openings at a certain speed ensures that an accumulation of fiber fly on the gripper drive elements and is avoided in their environment and thus it is excluded that fiber fly mixed with oil or fat-containing abrasion particles can get from the gripper drive into the fabric to be produced.
  • the invention is explained below using an exemplary embodiment.
  • the drawing shows the gripper drive and the surrounding housing in perspective.
  • the exemplary embodiment is based on the carrier element 1 for the weft thread, a gripper bar which carries at its front end a gripper 2 which has devices for gripping, holding and releasing the weft thread.
  • the design of the gripper 2 is not important for the invention. It is therefore not discussed in any more detail.
  • the carrier member 1 here consists of a U-shaped profile cross section with an integrated Rack or integrated rack-like toothing, with which at least one drive pinion 7 is meshingly engaged.
  • the drive pinion 7 is connected in a rotationally fixed manner to a drive shaft 7a, which drives the drive pinion 7 with an alternating direction of rotation according to double arrow 11.
  • the direction of rotation of the drive pinion 7 and the direction of movement of the carrier member 1 with the gripper 2 is indicated by a double arrow 11, 12.
  • the storage and guidance of the carrier member 1 takes place here in the example by rollers 4, 5, 6.
  • the rollers 4, 5 serve to guide the carrier member 1 vertically.
  • the lateral guidance of the carrier member 1 is carried out by at least one guide roller 6.
