Definitions

  • a pneumatic cleaning apparatus for looms which is of the type comprising a blower mechanism incorporating a number of blower conduit means provided with a plurality of blower nozzle means.
  • the blower conduit means are arranged at predetermined locations of the loom, and at least one of such blower conduit means is operably connected with movable components of the loom.
  • distributor conduit means serve to connect the blower conduit means with a common source of low pressure-blower air.
  • the present invention relates to an improved pneumatic cleaning apparatus for a loom.
  • a travelling blower unit is associated with a number of looms. This travelling blower unit moves back and forth along a rail above the looms. Furthermore, this known construction of travelling blower unit is provided with movable blower nozzles which are directed downwardly towards the loom and parts and components thereof. Such blower nozzles have the function of blowing away fly and fibers from the parts of the loom which are contacted by the air currents emanating from the blower nozzles during passage of the travelling blower unit over the looms.
  • a pneumatic cleaning device is also known to the art in which, in addition to a travelling blower unit which is associated with a number of looms, a suction mechanism is provided for each loom. These suction mechanisms of the individual looms, and each of which possesses a suction opening arranged beneath the associated loom at the floor of the weaving room, are operatively connected to a commonsuction conduit. A controllable flap mechanism is associated with each suction opening. More precisely, the control of this flap mechanism occurs as a function of the passage of the travelling blower unit over the associated loom.
  • the flap mechanism at the suction device of a loom is then completely opened when the travelling blower unit arrives at such loom and, thus, begins to impact this loom with a jet or current of blower air.
  • the dust and other contaminates which are placed into turbulence under the action of the blower air stream are, therefore, entrained by the suction device and removed by the suction channel.
  • the flap mechanism only 3,491,801 Patented Jan. 27, 1970 SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide an improved pneumatic cleaning apparatus which effectively overcomes the drawbacks of the prior art structures.
  • Another more specific object of this invention relates to an improved pneumatic cleaning apparatus for textile machines, in particular looms, which is readily capable of elfectively removing dust, fly, fibers, and other contaminates, from the textile machine in an extremely efficient, positive and reliable manner.
  • Still a further significant object of the present invention relates to an improved pneumatic cleaning apparatus for looms which allows the removal of foreign matter such as, dust, fly, fibers, and the like, from the componen s or parts of the loom in a most efficient, positive and effective manner, thereby improving the working conditions in the weaving area, as well as improving the quality of the woven cloth.
  • the present invention recognizes that an improved cleaning action at looms cannot be obtained by increasing the pressure of the blower air, rather a apparatus is provided which is capable of continuously impacting with air those components or parts of the machine which tend to become contaminated and, therefore, prevent a settling of fly and dust upon these components.
  • blower conduit means are arranged at predetermined locations of the loom. At least one of these blower conduit means is connected with movable components or parts of the loom, and further, these blower conduit means operably communicate with a common source of low pressureblower air through the agency of distributor conduit means.
  • the latter incorporates a suction device which is disposed beneath the loom.
  • the blower nozzles of the inventive cleaning apparatus are preferably uniformly distributed over the width of the loom and the suction device possesses an air inlet which narrows towards the bottom and which extends substantially transverse to the direction of the warp over a considerable portion of the width of the loom.
  • These blower nozzles can be advantageously formed by providing openings at the blower conduit means which extend transverse to the direction of the warp, whereby, for instance, the distributor conduit means are connected at their front end to the associated blower conduit means.
  • FIGURE 1 is a sectional view through a preferred form of inventive cleaning apparatus provided at a loom, and wherein such sectional view is taken substantially parallel to the warp threads;
  • FIGURE 2 is a fragmentary view depicting a second embodiment of a blower conduit which is associated with the warp stop motion.
  • reference numeral broadly designates the schematically illustrated loom which is secured to the floor 12 of the weaving room or area by means of its lateral frame members 11.
  • This loom 10 is of standard construction and, therefore, possesses conventional components, such as a warp beam 16, a warp stop motion 18, harnesses 20, a fell or weft impact edge 21, a sley 22 which is mounted for pivotal movement at location 70, a breast beam 26 and a cloth beam 28.
  • the warp or Warp threads as delivered by the warp beam 16 are designated by reference numeral 14.
  • the exemplary illustrative embodiment of inventive cleaning apparatus which is provided at the loom 10 is designated by reference numeral 30.
  • This cleaning apparatus 30 embodies a pair of cover plate members 31 and 32 which are inclined towards one another, and which collectively cover a portion of the floor 12 which is located beneath the loom 10. Furthermore, these cover plate members 31 and 32, together with the lateral frame members 11 form a funnel means 33. It will be recognized that whereas the cover plate member 31 terminates at the region of the warp beam 16 and beneath the warp stop motion 18, the other cover plate member 32 extends up to the region of the cloth beam 28. Furthermore, the funnel means 33 merges or opens into a suction opening 34 of a suction device which includes a suction channel 36. This suction opening 34 communicates via the suction channel 36 with the non-illustrative suction flange means of a suitable non-illustrative air conveying device.
  • an air box or compartment 38 is located beneath the cover plate member 31 and will be understood to extend over the width of the loom.
  • This air box 38 communicates with a suitable air supply system. More precisely, it will be recognized that the air box 38 is operably associated via an inlet opening 40 and an air channel 42 with a non-illustrated suitable source of blower air.
  • the portion of the cover plate member 31 which is situated above the air box 38 possesses a blower nozzle 44 which is formed by the overlapping marginal portions 35 and 41 of this cover plate member 31. The discharge opening of this blower nozzle 44 is directed, as shown, towards the suction opening 34.
  • an air distributor flange unit 55 is connected to at least one end face or side of the air box 38, as best shown by referring to FIGURE 1.
  • blower conduit means are associated with those components or parts of the loom 10 which are particularly subjected to contamination by dust and fly and which are particularly in danger of having deposited thereon such dust and fly.
  • one such blower conduit means 53 is associated with the warp stop motion 18, a further blower conduit means 54 with the harnesses and an additional blower conduit means 56 with the reed 24.
  • blower conduit means 53 it will be seen that such is arranged above the warp stop motion 18 and possesses blower nozzle means 68 which are directed towards this warp stop motion 18, that is to say, in this instance blower nozzle means which are directed downwards.
  • blower conduit means 54 is located at the lowermost position of the lower frames of the harnesses 20 at the side of the warp stop motion 18 and, further, this blower conduit means 54 is equipped with a number of blower nozzles 64 which are directed approximately horizontally towards the harnesses 20 and a further number of blower nozzles 66 which are directed downwardly towards the funnel means 33.
  • blower conduit means 56 is rigidly connected to the sley 22 of the loom 10. This blower nozzle means 56 is provided with blower nozzles 62 which are directed upwardly towards the reed 24 as well as other blower nozzles 60 which are directed towards the harnesses 20.
  • blower nozzles 60, 62, 64, 66 and 68 are uniformly distributed in one or a number of rows over the length of the associated blower conduit means 56, 54 and 53, and can be formed by the provision of circuit-shaped or elongated openings provided in each of the associated blower conduit means.
  • each such distributor conduit means in the exemplary illustrative embodiment, consists of a respective branch stud or pipe 45, 48 and 51 connected with the air distributor flange means 55, further a respective flexible hose 46, 49 and 57, as well as a respective pipe or conduit member 47, 50 and 52 coupled with the end face or portion of the associated blower conduit means 53, 54 and 56, respectively.
  • the use of the flexible hose 57 enables the intermediate pipe 52 to follow the movements of the sley 22 and during such movements to continually deliver air from the distributor flange means 55 to the associated blower conduit means 56.
  • blower air is delivered to the blower conduit means 53, 54 and 56 via the air supply conduit 42, the air box 38, the air distributor flange means 55 and the just-considered corresponding distributor conduit means.
  • Air emanating from the blower conduit means 53 is guided via the associated blower nozzle means 68 onto the warp stop motion 18.
  • the air current or stream which escapes from the blower nozzle means 64 of the blower conduit means 54 impacts against the confronting side or face of the harnesses 20.
  • the blower nozzle means 60' of the blower conduit means 56 attached to the sley 22 of the loom oscillates with this sley between the harnesses 20' and the fell or weft impact edge 21.
  • the air which flows out of the blower nozzle means 60 impacts in pulsating fashion the side of the harnesses 20 which face away from the blower nozzle means 54.
  • the air emanating from the blower nozzle means 62 of the blower conduit means 56 simultaneously impacts against the reed 24 which is fixedly secured to the sley 22.
  • the air which is blown between the warp stop motion 18, upon leaving the latter, is deflected in the direction of the funnel means 33 and thereby forms an air curtain which extends over the width of the loom.
  • This air cur-' tain screens the warp beam 16 against the entry of fly and dust from the shed and the zone of movement of the sley 22.
  • a further directed air jet from the blower nozzle means 66 of the blower conduit means 54 is directed towards the funnel means 33.
  • the fly and dust which is entrained by the air currents is blown towards the bottom of the funnel means 33 and is sucked off by the suction opening 34 and conducted away by the suction channel 36.
  • the air stream escaping from the slotted nozzle 44 likewise wipes across the lower portion of the side wall of the cover plate member 31 and blows any fly and dust or the like which has dropped or collected at this location towards the suction opening 34.
  • FIGURE 2 there is depicted a further embodiment of a blower conduit or channel 53' which is located at the region of the warp stop motion 18.
  • This blower conduit or channel 53' possesses a substantially rhombic-like cross-section, whereby the lateral or side walls 80 bounding the blower conduit or channel 53' possess a relatively steep inclination, as shown, and at the lower portion of this conduit 53 form a slotted nozzle means 70 which extends over the entire length of the associated blower conduit or channel 53.
  • blower channel or nozzle means 53' is rotatably mounted at its upper portion by means of two pins or cams 74 at the frame means 11 of the loom and, furthermore, is disposed in driving connection with a revolving shaft member 73 of the loom 10 through the agency, for example, of a rod 71 and an associated crank pin 72. Consequently, this blower conduit or channel means 53 is thus subjected to an oscillatory movement about an axis which is parallel to its longitudinal axis. As also will be seen by referring to FIGURE 2, the upper side walls' 80 of the blower conduit means 53' intersect one another at an acute angle.
  • blower conduits which. extend substantially parallel to the weft thread can, of course, also be supplied at both of their ends with blower air. It is naturally also possible to connect the blower conduits 54, 56 with the air box 38 or its distributor flange means 55 through the agency of a T-pipe member which is mounted at the center region of these blower conduits 54, 56.
