Definitions

  • the invention relates to a dedusting device for flat knitting machines, with suction nozzles which are arranged on the carriage of the flat knitting machine and are aligned with the needle beds and which are connected to a suction motor arranged on the carriage and driven by an electric motor.
  • the invention has for its object to design a dedusting device of the type mentioned so that it gives a high efficiency with a favorable power to weight ratio and can be operated as maintenance-free and energy-saving as possible.
  • the use of two separately controllable and switchable suction fans results in the advantage that, instead of a large-volume and therefore bulky dedusting device, two smaller suction fans, which can be accommodated more easily on the slide, can be used.
  • the dedusting can be limited to the front needle bed without blocking devices for a part of the suction channels, and the energy expenditure for the dedusting of the front and the rear needle bed can be rationally adapted to the different degree of use through different actuation intervals.
  • the amount of energy required for fluff suction is very greatly reduced in the dedusting device designed according to the invention by lowering the suction nozzles down to the stitch formation area of the needle heads, the suction nozzles advantageously their two carriage direction sides can have lateral opening edge recesses, which give the needle heads which have been run over and which are exposed to the suction effect, free space for immersion and for executing the needle tongue impact. Due to the reduced energy expenditure, smaller and less powerful and therefore also lighter suction fans can be used, the energy saving being able to be reduced even further by the formation of the suction fans and the suction channels leading from the suction nozzles to the suction fans.
  • the suction channels can expediently consist of hoses with a circular cross-section, which have a highly smooth and advantageously also an electrically antistatic inner surface, which ensures low-resistance fluff and dust transport into the dust collection container of the suction fan.
  • the suction fans can be designed such that the suction channels leading from the suction nozzles to the associated suction fan tangentially open into the upper end face region of a vertically oriented, circular-cylindrical dust collecting container, the upper end face of which has a central sieve opening, above which the suction fan is arranged.
  • the suctioned dust is agglomerated by cyclonic swirling and falls faster to the ground due to this compaction.
  • the expediently circular-cylindrical dust collecting container can be designed with a relatively small volume without shortening the emptying intervals.
  • a dedusting device designed in accordance with the invention can thus be arranged in a relatively small and compact design with short suction channels on the side and above the slide driving device on the slide, the two suction fans advantageously being arranged one behind the other and with opposite rotors in the running direction of the slide. Due to the counter-rotating rotors, the torque loads of the carriage are largely canceled out when the two suction fans are operated simultaneously, as a result of which the fastening construction for the dedusting device can be designed more easily.
  • FIG. 1 shows, from a flat knitting machine, the machine frame 10, the two needle beds 11 and 12, the machine slide 13 with its two lock plates 15 and 16 connected by clips 14, three thread guide rails 17 spanned by the clips 14, a bobbin table 18 ,
  • a support beam 25 extends from the brackets 14 of the carriage in the area between the reel table 18 and the carriage driving device 24 to the rear the flat knitting machine.
  • the power supply to the carriage 13 takes place via this support beam 25 from a cable guide device 26, and suction fans 27 of a dedusting device of the slide 13 are also fastened to this support beam 25, which have front and rear suction nozzles 29 and 30 reaching into the knitting area 28, which have Round hoses 31 and 32 with a smooth inner surface are connected to the suction fan part of the dedusting device.
  • the dedusting device attached to the carriage 13 of the flat knitting machine has two arranged one behind the other in the direction of carriage movement Suction fan 27 and 27.1, which are of the same design.
  • Its electric drive motor 33 is arranged vertically with its axis and drives a fan wheel arranged in a worm-like housing 34.
  • the two suction fans 27 and 27.1 are arranged so that their rotors are common with the impellers, not shown.
  • the impellers each suck in the air in the axial direction through a sieve opening 35 and convey the sucked-in air outwards via a tangential channel 36 or 36.1 to the rear of the flat knitting machine.
  • the suction nozzles 29 and 30 are brought as far as possible to the stitch formation area above the comb gap formed by the two needle beds 11 and 12. They are provided at the end of the nozzle with lateral opening edge recesses 38, which give the needle heads 39, run over by the suction nozzles 29 and 30 during the carriage movement, with their needle tongues 40, free space for receiving the thread 41 to be knitted and for the tongue flap.
  • FIG. 2 shows the control panel 42 of a control device of the dedusting device, with which an intermittent operation of the two suction fans 27 and 27.1 can be set independently of one another via adjustable time stages.
  • the suction and interval times can be selected using buttons 43 in accordance with the processed yarns and the type of knitted fabric formed and also made visible on a display device 44.
