Definitions

  • the present invention relates to a fiber bundle collecting device and, more specifically, to a fiber bundle collecting device which is arranged on the downstream side, for example, of the drafting device (draft part) of a spinning frame and which collects a fiber bundle drafted by the drafting device.
  • German Patent Application Laid-Open No. DE19708410A1 discloses a fiber bundle collecting device of this type, in which, as shown in Figs. 10, 11(a) and 11(b), on the downstream side of a final roller pair 71 constituting a drafting device, there is provided a send-out roller pair 73 equipped with an air-permeable apron 72 forming a fiber bundle conveyance surface, which is provided with an air suction device 74 for applying suction airflow to the conveyance surface of the air-permeable apron 72.
  • suction airflow is applied to the conveyance surface of the air-permeable apron 72 through a groove hole formed in an apron guide 75 for guiding the air-permeable apron 72.
  • a pair of send-out rollers 73a around which the air-permeable apron 72 is wrapped is supported by a support portion 76 in a cantilever-like fashion through a spindle 77, and are rotated through friction with friction roller portions 78a of a rotation shaft 78 arranged parallel to a front bottom roller 71a.
  • the frictional force for the friction roller portions 78a is secured by the pressurizing force of send-out rollers 73b supported by a weighting arm and pressed against the air-permeable apron 72 at positions corresponding to the send-out rollers 73a.
  • the rotation shaft 78 is driven by a motor provided at the gear end of the machine base through a gear row, the production of the spinning machine is difficult with improvement of the conventional machine alone, and it is necessary to newly alter the construction of the machine base of the spinning machine as a whole including the arrangement of the drafting device. If, of the send-out roller pair 73, the send-out roller 73a around which the air-permeable apron 72 is wrapped were formed on the rotation shaft 78, it would be possible to diminish the arrangement space for the fiber bundle collecting device. However, as compared with the middle apron of the drafting device, the air-permeable apron 72 is more subject to wear, and its replacement cycle is relatively short.
  • the present invention has been made in view of the above problem in the prior art. It is a first object of the present invention to provide a fiber bundle collecting device in which the driving roller and the sucking portion constituting the fiber bundle collecting device are formed as a unit for each of a predetermined number of spindles, facilitating the mounting and maintenance and the replacement of the air-permeable apron.
  • a second object of the present invention is to provide a fiber bundle collecting device for a spinning machine which can be realized through simple modification of a spinning machine equipped with a conventional drafting machine.
  • a first aspect of the present invention relates to a fiber bundle collecting device for a spinning machine, which is provided on the downstream side of a final send-out roller pair of a draft part of the spinning machine, the device including: a send-out portion having a nip roller; a sucking portion equipped with suction holes provided so as to extend at least on the upstream side of a nip point of the send-out portion with respect to the direction in which a fiber bundle moves; and an air-permeable apron constituting the send-out portion and adapted to rotate along the sucking portion.
  • a rotation shaft has a torque transmitting portion for transmitting the torque of a drive source; is formed in a predetermined length corresponding to a plurality of spindles; has at a position corresponding to each spindle a drive roller portion around which a part of the air-permeable apron is wrapped; and has at a plurality of positions portions to be supported that are supported by support portions provided in a machine base frame.
  • a sucking means extends parallel to the rotation shaft; is equipped with the suction holes in correspondence with the spindles; and is equipped with suction pipes having slide surfaces around which a part of the air-permeable apron is wrapped so as to cover the suction holes.
  • Fig. 1 is a schematic side view, partially in section, showing one side of a drafting device
  • Fig. 2 is a partial schematic view with the top roller side omitted, showing the relationship between the bottom roller of the drafting device, the sucking portion of the fiber bundle collecting device, and the bottom nip roller

  • the lock state is canceled.
  • a fiber bundle collecting device 30 is arranged on the downstream side of the final send-out roller pair of the drafting device 11.

  • Fig. 7 is a perspective view showing a state in which the suction pipes 44 and 45 are mounted to one side of the connection pipe 46.
  • the suction pipe 44 has a slide guide surface 44b having slit-like suction holes 44a extending on the upstream side with respect to the direction in which the fiber bundle (fleece) F moves with the nip point of the bottom nip roller 34a being therebetween.

  • the rotation shaft 34 and the sucking portion 32 are not restricted to the construction in which four spindles constitute one unit; it is also possible to adopt a construction in which the spindles between the roller stands 15 (e.g., eight spindles) constitute one unit. In this case, the number of parts of the sucking portion 32 and the rotation shaft 34 necessary for one spinning machine is reduced, and it is possible to reduce the number of connection pipes 47 connecting the suction duct 43 and the sucking portion 32, so that the requisite labor for the mounting is reduced. Further, the roller stands 15 are generally arranged at intervals corresponding to the installment intervals of the spring pieces forming the base frame of the spinning machine, and, in many cases, the suction duct 43, etc. connected have a length corresponding to the interval. Thus, by adopting a construction in which the sucking portion 32 and the rotation shaft 34 also have a length corresponding to that length, the packing, etc. at the time of transportation is facilitated.

  • the positions of the portions to be supported provided on the rotation shaft 34 are not restricted to the ends of the rotation shaft 34; they may also be provided at middle positions. However, by providing them at the ends, interference with the suction pipes 44 and 45 is avoided more easily.
  • the number of portions to be supported provided on the rotation shaft 34 is not restricted to two; it is also possible to provide three or more portions to be supported.

  • the configuration of the suction pipes 44 and 45 may be such that the end portions on the side opposite to the side opposed to the connection pipe 46 are blocked. In this case, there is no need for the end plugs 39 to hermetically block the end portions of the suction pipes 44 and 45; it is only necessary to provide an engagement hole 39b into which the bearing 38 is to be fitted and engagement portions (holes) into which the end portions of the suction pipes 44 and 45 are to be fitted, whereby the production is facilitated.
