Definitions

  • the invention relates to a cleaning apparatus for a draft roller in a draft apparatus.
  • Draft rollers for a draft apparatus in a spinning machine, a roving machine or the like are constituted of top rollers on the upper side and bottom rollers on the lower side. Since a sliver is drafted between the top rollers and the bottom rollers, honey dew in a case where a raw material of a sliver is cotton, an oil solution in a case where a raw material of sliver is chemical fibers or other material such as cotton fly is attached on the outer surface of a draft roller. Hence, a cleaning apparatus for removing such attachment regularly and cleaning the roller is equipped to the draft roller.
  • Patent Document 1 a construction in which a belt constituted of a flexible member (a fin) is brought into contact with a draft roller to thereby slap down cotton fly or the like
  • Patent Document 2 a construction in which a rubber pat is brought into contact with the outer surface of a draft roller to scratch off cotton fly or the like
  • a cleaning apparatus using a belt or a rubber pat in which the belt or the rubber pat has a weak scratching force so as to contact a roller surface and rub it along tangent direction and cannot remove with certainty for cleaning.
  • the apparatus using the rubber pat since the pat is regularly moved away from a roller to remove the attachment down, there has remained a problem that the attachment on the roller cannot be removed when the pat moves away.
  • the invention has been made in view of the above problem and it is an object of the invention to provide a cleaning apparatus capable of removing even an attachment such as honey dew or an oil solution strongly stuck on the outer surface of a roller with certainty to thereby cleaning it.
  • a cleaning apparatus for a draft roller concerning the invention is equipped with a scraper member extending in the axial direction of the draft roller, and having a sharp end edge in contact with the outer surface of the draft roller and the sharp end edge of the scraper member is brought into contact with the outer surface of the draft roller in parallel to the central axis line thereof.
  • press means for pressing the scraper member against the outer surface of the draft roller in press contact therewith are provided to the cleaning apparatus.
  • the cleaning apparatus is equipped with a holder member for holding the scraper member, the holder member is provided to bearing houses of the draft roller so as to be freely mounted or dismounted, and the bearing houses position the holder member.
  • the bearing houses have respective holder support holes for inserting or drawing out the holding member so as to be freely mounted or dismounted, is the scraper member held so that it can freely protrude from or retreat into the holder member, has tapered portions on both ends thereof in a way such that a width increases toward the center of the holder member in a direction of inserting or drawing out of the holder member, wherein when the holder member is inserted or drawn out, a tapered portion is brought into contact with the holder support hole and the scraper member sinks in the holder member.
  • the scraper member is made of synthetic resin and lower in hardness than the outer surface of the draft roller.
  • a cleaning apparatus of the invention is in contact with the draft roller so that the sharp end edge of the scraper member is in parallel to the central axis line of the draft roller, honey dew, oil solution or the like attached on the outer surface of the roller is scratched off by the sharp end edge with certainty as the roller rotates.
  • honey dew, oil solution or the like can be strongly scratched off under pressure from the press member. Even if the sharp end edge of the scraper member is worn more or less as time elapses, the press member can maintain a prescribed press force against the roller; therefore, unevenness in cleaning can be minimized.
  • the holder member holding the scraper member or the like can be dismounted and maintenance such as adjustment of a roller gauge or exchange of scraper members can be conducted with ease by providing the holding member to the bearing house of the draft roller so as to be freely mounted or dismounted.
  • the scraper member is made of synthetic resin to thereby enable a honey dew or oil solution to be scratched off with certainty with a hard characteristic of a synthetic resin. Since such a scraper is excellent in productivity and cost and softer than the metal draft roller, no damage occurs on the outer surface of the roller in a press contact with the scraper.
  • a spinning machine of the embodiment has many spinning units 15, 15, ⁇ in parallel between a motor box 16 and a dust box 17.
  • a spinning unit 15 includes a draft apparatus 10 having a back roller 1, a third roller 2, a second roller 3 and a front roller 4 therein and a sliver S drawn out from a sliver cans (not shown) is drafted.
  • An air spinning section 11 is provided below a draft apparatus 10 and a sliver S sent out from a draft apparatus 10 is spun by the air spinning section 11.
  • the spun sliver S becomes yarn Y and the yarn Y is drawn out by a yarn feed roller 12 and taken up on a take-up package 13 while being traversed.
  • Back rollers 1 and third rollers 2 are, as shown in Fig. 2, constituted of top rollers 1a and 2a disposed in upper positions and bottom rollers 1 b and 2b disposed in lower positions, and a sliver S is caused to pass through between the top rollers 1 a and 2a and the bottom rollers 1 band 2b and drafted.
  • a sliver S is drafted, oil solution or honey dew, or cotton fly attaches to the outer surfaces of the rollers of a draft apparatus.
  • the cleaning apparatuses 5 and 5 are equipped to the lower sides of the back roller 1 and the third roller 2 for removing attachment on the bottom rollers 1 b and 2b.
  • Cleaning apparatuses 5 and 5 each, as shown in Fig. 3 to 6, provide a scraper member 50, and the scraper member 50 is held by a holder member 51.
  • a sharp end edge 50a is formed at the distal end of the scraper member 50, and the sharp end edge 50a is disposed so as to be in contact with the outer surface of each of the bottom rollers 1 band 2b.
  • the scraper members 50 are pressed against the central axis lines 1 c and 2c of respective bottom rollers 1 band 2b by a press member 52 provided in the holder member 51, and the sharp end edge 50a of the scraper member 50 is in press contact with the outer surface of respective the bottom rollers 1b and 2b along the entire length.
  • a suction member 55 is installed below the scraper member 50 and cotton fly or the like scratched off can be sucked and removed by a suction action of the suction member 55 with certainty.
  • the suction member 55 is constructed so as to obtain a suction force by being connected to the dust box 17 or the like of the spinning machine.
  • the back bottom roller 1 b is, as shown in Fig. 3, provided with shafts 1 d and 1 d on both sides thereof.
  • Bearing houses 20 and 20 are disposed on both sides of the back bottom roller 1b, and roller support holes 20b and 20b provided in the top portions of the bearing houses 20 and 20 support the shafts 1 d and 1 d and rotatably support the back bottom roller 1 b.
  • Holder support holes 20a and 20a are provided in the bottom portions of the bearing houses 20, and a holder member 51 is inserted through and supported by the holder support holes 20a and 20a.
  • the holder member 51 and the scraper member 50 are provided so as to extend in the axial direction of the back bottom roller 1b, and the sharp end edge 50a disposed in the axial direction of the scraper member 50 is in contact with the outer surface of a third bottom roller 2b.
  • the holder member 51 provides a housing groove 51 a in the axial direction.
  • the press member 52 constituted of a leaf spring or the like is housed in the housing groove 51 a and the scraper member 50 is disposed on the press member 52.
  • the press member 52 presses the scraper member 50 against the back bottom roller 1b, thereby the sharp end edge 50a of the scraper member 50 is in press contact with the outer surface of the bottom roller 1 b.
  • the scraper member 50 is made of a hard synthetic resin less in deformation and adopted so as to be lower in hardness than the roller, which is an object to be cleaned. With such a construction adopted, the outer surfaces of the metal bottom rollers 1 b and 2b are not damaged physically during cleaning.
  • the sharp end edge 50a of the scraper member 50 is designed so as to be constantly aligned with the central axis line 1 c of the back bottom roller 1b. That is, each of the holder support hole 20a and 20a has a sectional shape of almost an ellipse and the holder member 51 is formed so as to have a sectional shape of a polygon that can be inserted into the holder support holes 20a and 20a, and thereby, the holder member 51 inserted through the holder support holes 20a and 20a does not rotate in company with rotation of the back bottom roller 1 b and constantly assumes a position so that the sharp end edge 50a is in parallel contact with the central axis line 1c.
  • the holder member 51 is constructed so as to be freely mounted to or dismounted from the bearing houses 20 and 20, whereby operations is easy in maintenance such as exchange of scraper members 50 or adjustment of a roller gauge.
  • Figs. 6(a) and 6(b) are partially sectional view for describing a procedure for mounting or dismounting a holder member.
  • the scraper member 50 is constructed so as to freely protrude from or retreat into the housing groove 51 a of the holder member 51 by the press member 52. Tapered sections 50b and 50b are formed on both sides of the scraper member 50.
  • the holder member 51 When the holder member 51 is, as shown in Fig. 6(a), dismounted from the bearing houses 20 and 20, the holder member 51 is at first pulled in the axial direction (the direction of inserting or drawing out) C to thereby cause a tapered portion 50b of the scraper member 50 to be in contact with a hold support hole 20a. Then, the holder member 51 is further pulled in the axial direction (the direction of inserting or drawing out) C, whereby the scraper member 50 is pressed downwardly against a press force of the press member 52 and housed and sinks in the housing groove 51 a, and in this state, the holder member 51 is drawn out through the holder support hole 20a and can be dismounted.
  • tapered portions 50b and 50b are formed on both ends of the scraper member 50 in a way such that a width increases toward the center of the holder member 51 in a direction of inserting or drawing out of the holder member, and the holder member 51 can be inserted into or drawn out from the holder support holes 20a smoothly on both sides of the axial direction.
