Definitions

  • Thread and fly suction devices for spinning machines which include vertical suction ducts extending along the longitudinal center plane of the machine and having air inlets adjacent to the drafting arrangements. These ducts taper in the upward direction and are provided with suction fans placed in the upper portions of the ducts for producing an upwardly directed air current. A netting acting as a filter is placed across the outlet on top of the ducts. The netting must be periodically removed for cleaning which involves additional time-consuming work.
  • the system according to the invention includes a plurality of vertical ducts placed along the center line of the spinning machine and having inlets adjacent to the drafting arrangements.
  • the cross section of the vertical ducts becomes smaller in the upward direction and the outlets of the vertical ducts are connected to a horizontal duct placed on top of the spinning machine and extendingin the longitudinal direct-ion thereof.
  • a suction fan is provided in each vertical duct adjacent to the horizontal duct for drawing air from the inlet of the respective vertical duct through the vertical duct and discharging the air into the horizontal duct on top of the spinning machine.
  • At the junctions of the vertical ducts and the horizontal duct means are provided for diverting the air discharged by the suction fans into the horizontal duct to cause the air discharged by all fans to move in the same direction in the duct.
  • the horizontal duct has perforated wall portions permit-' t-ing escape of air from the inside of the horizontal duct to the outside but retaining pieces of thread fiy lint and dust within the horizontal duct.
  • the retained material has a tendency to stick to the inside of the perforated wall portions of the horizontal duct.
  • the platelike means forming part of the carriage may be slightly spaced from the perforated wall portions so that some air can ice escape therethrough and the platelike means may be so shaped as to direct the air escaping through the perforated wall portions downwards and on to the spinning machine for removing dust therefrom. This dust-laden air is then drawn in through the inlets of the upright portions of the duct system.
  • the platelike means associated with the carriage may include hinged flaps for adjusting theeffective area of the platelike means and also the air guide effect of said means.
  • FIG. 1 is a lateral elevation of a portion of a spinning machine equipped according to the invention.
  • FIG. 2 is a cross sectional elevation of the spinning machine shown in FIG. 1 the section being made along line II-II of said figure.
  • FIG. 3 is a perspective view of a portion of the duct and self-cleaning system according to the invention.
  • FIG. 4 is a side elevation of a carriage forming part of the system according to the invention the carriage being equipped with modified propelling means.
  • numeral 1 designates a frame on which a creel 2 is mounted in the conventional manner, the creel supporting a plurality of vertical skewers for holding roving bobbins 3 grouped on either side of the machine and supplying spinning material to drafting arrangement 4.
  • Suction duct means are placed along the longitudinal center plane of the spinning machine. These duct means have laterally extend ing inlet portions 6 provided with inlet slots 7 which are below the drafting arrangements 4 and extend longitudinally of the machine.
  • the suction duct means have upright portions 5 which are tapered in the upward direction and longitudinally of the machine.
  • a housing 8 containing a suction fan 9 is provided for drawing air into the duct system through theinlets 7 and discharging the air in upward direction.
  • the tops of the housings 8 are connected for air flowto the bottom of a duct 10 extending longitudinally of the machine and having a substantially rectangular cross sectional configuration.
  • the lateral walls and the top wall of the duct 10 are perforated to form a strainer through which the air discharged by the fans 9 moves to the outside of the duct 10. Since the perforated wall portions of the duct 10 are very large compared with the rate of flow of the air through the duct and through the the junctions of the blower housings 8 and the duct 10 for diverting the air leaving the housings 8 and matter carried along by the air into the longitudinal direction of the duct 10 so that the air moves from the left end to the right end of the spinning machine shown in FIG. 1.
  • the right end of the longitudinal duct 10 terminates in a vertical duct 12 which is also provided with perforated walls.
  • the vertical duct 12 terminates in a container 13 placed on the floor of the spinning room and receiving matter carried along by the air.
  • the container 13 is pref erably made removable and interchangeable.
  • rails 14 and 15 are provided on top and longitudinally of the duct 10. These rails support running Wheels 16 of a carriage 17 which can be pulled along the duct 10 by means of an endless rope 19 laid around pulleys 18 at the ends of the spinning machine, only one pulley 18 being shown in FIG. 1.
  • the carriage 17 is provided with platelike vertical lateral members 21 which are adapted to cover portions of the perforated lateral walls 23 of the longitudinal duct 10, a slight clearance 24 being provided between the members 21 and the lateral walls 23 of the duct 10.
  • a similar clearance is provided between the top wall of the duct and a covering plate 17' (FIG. 3) provided on top of the carriage 17. The length of the latter corresponds approximately to the spacing between two fan housings 8.
  • FIG. 4 illustrates a modified propelling system for the carriage 17 which omits ropes and belts.
  • a propelling unit including an electric motor 28 driving an air propeller 29 is provided on either side of the carriage and is swingable on a horizontal axis which is normal to the propeller shaft and to the longitudinal axis of the duct 10.
  • Abutments 31 and 33 extend from the lateral plates 21 supported by the carriage 17, limiting the rocking movement of the units 28, 29. In the position of the units shown in FIG. 4, the air propellers 29 move the carriage from the left to the right.
  • the lateral plates 21 forming part of the carriage 17 are provided with flaps 35 which are connected to the plates 21 by means of self-locking hinges 34 so that air can be directed onto the bobbins 3 to most efliciently blow undesired matter therefrom.
  • the system according to the invention operates as follows:
  • the air discharged by the fans 9 passes through the perforated wall portions of the longitudinal duct 10 to the outside of the duct. Impurities, such as pieces of threads, fly and dust, are retained on the inside of the perforated wall portions and form a filter retaining fine dust. Matter which does not settle on the inside of the perforated wall portions is moved along through the duct 10 by the air current directed by the diverting plates or bafiles 11 and is finally deposited in the container 13. The fly and dust settled on the inside of the perforated wall portions of the duct 10 must be periodically removed. This is done by moving the carriage 17 along the duct 10 and thereby temporarily covering the outside of the perforated wall portions.
  • air suction duct means having inlets extending longitudinally of the machine and upright portions, a horizontal duct extending longitudinally of the machine, said upright portions terminating in said horizontal duct, suction fans individually placed in said upright portions for drawing air through said inlets into said upright portions and delivering the air into said horizontal duct, the latter having perforated wall portions permitting air to escape to the outside of the horizontal duct and retaining threads, fly and dust within said horizontal duct, a carriage movably supported by said horizontal duct to move lengthwise of said horizontal duct, said carriage including means covering said perforated wall portions for impeding flow of air therethrough, and means operatively connected to said carriage for moving said carriage along said duct for periodically interrupting pressing of fly and dust to the inside of said perforated wall portions by the air escaping to the outside of the horizontal duct and promoting flow of air and of fly and dust inside said horizontal duct.
  • guide means placed in said horizontal duct at the junctions of the latter and said upright duct portions for unidirectionally diverting the air leaving said upright portions into the direction of the longitudinal extension of said horizontal duct.
  • a fly and dust accumulating receptacle connected to the end of said horizontal duct towards which end the air flows in said horizontal duct.
  • said means covering said perforated wall portions include plates slightly spaced from said perforated wall portions, said plates being adapted to permit air to escape through said perforated wall portions and to guide the escaped air towards the spinning machine for blowing fly and dust therefrom.
  • said plates include hinged flaps for adjusting the effective area and guide effect of said plates.
