Definitions

  • the present invention relates to a cloth winding apparatus for use in a weaving loom wherein torque of loom drive is transmitted to a cloth roll through a torque limiter comprising a pair of friction clutch plates pressed against each other by pressure of a spring and a cam mechanism is provided which is adepted to change the pressure of the spring according to the motion of a feeler lever which is swingable in response to a change in cloth roll diameter.
  • a cloth winding apparatus of the above type for use in a weaving loom is disclosed by Publication of the Japanese Patent Application No 55-163241 (1980)
  • an end cam is attached to a rotatable shaft supporting a feeler lever which is swingable with rotation of the shaft, and a cam-operated lever having a cam follower is adapted to rotate in conjunction with the swinging motion of the feeler lever in response to an increase of diameter of a cloth roll of the loom.
  • Torque provided by a loom drive is transmitted to the cloth roll through a pair of friction clutch plates pressed against each other by a spring which is installed between the cam-operated lever and one of the above paired clutch plates.
  • the pressure of the spting will act on the feeler lever by way of the cam-operated lever, the cam and the rotatable shaft so as to press the feeler lever against the peripheral surface of the cloth roll.
  • the feeler lever is caused to swing back rapidly under the influence of the spring pressure. Such rapid movement of the feeler lever makes it troublesome to remove the cloth roll from the loom.
  • an object of the present invention is to provide a cloth winding apparatus that facilitates removal of the cloth roll from the weaving loom.
  • a cloth winding,apparatus for use in a weaving loom including a torque limiter comprising a pair of friction clutch plates pressed against each other by pressure of a spring for transmitting through said clutch plates torque of a loom drive to a cloth roll, a feeler lever swingably supported or a rotatable shaft, said feeler lever being swingable about said shaft in response to a change in cloth roll diameter, and a cam mechanism adapted to change the pressure of said spring according to the swinging motion of said feeler lever, said shaft being adapted to transmit the swinging motion of said feeler lever to said cam machanism, wherein said feeler lever is supported on said shaft rotatably and axially slidably relative to said shaft, and said apparatus further includes a relative rotation preventing mechanism provided between said feeler lever and said shaft fot preventing the rotation of the feeler lever relative to the shaft when the feeler lever is lacated at its cloth roll diameter detecting position, said mechanism being disengageable to allow the relative rotation of said shaft
  • the feeler lever In removing the wound-up cloth toll from the loom, the feeler lever is akially shifted along the shaft, on which it is supported, from its normal cloth roll diameter detecting position. By so shifting the feeler lever, the relative rotation preventing mechanism is disengaged to allow the shaft to be rotated relative to the feeler lever by the action of the spring and the cam mechanism. Because no more spring pressure acts on the feeler lever aftet the above relative rotation, the lever will not be rotated rapidly even if the cloth roll is removed form the loom.
  • FIGS 1 to 3 show the folowing:
  • Reference numeral 1 designates a surface roller operatively connected to a loom drive (not shown) through a transmission (not shown either) for drawing a cloth W.
  • the surface roller 1 has a shaft 1a extending from one end thereof.
  • An end cam 2 and a driven clutch plate 3 are supported on the surface roller shaft 1a in a rotatable, but not axially slidable relation to that shaft.
  • a drive clutch plate 12 which is interposed between the end cam 2 and the driven clutch plate 3 is supported on the surface roller shaft 1a in an axially slidable, but not rotatable, relative to the shaft.
  • the end cam 2 has formed on its outer surface a pair of cam projections 2a.
  • the driven clutch plate 3 has formed on its peripheral edge a circumferential sprocket 3a. Below the driven clutch plate 3thereof a small-diameter sprocket wheel 5, and the shaft 4 and the driven clutch plate 3 are operatively connected by means of an endless chain 6 trained round and between the sprocket 3a on the clutch plate 3 and the small-diameter sprocket wheel 5.
  • the shaft 4 is operatively connected to a cloth roller shaft 7a for a cloth roll 7.
  • a cloth guide bar 22 suspended at its opposite ends by strings 23 is disposed engageably with a cloth W so as to guide the cloth and to simultaneously remove its crease while it is being wound round the shaft 7a.
  • a bracket 8 is mounted on the surface roller shaft 1a in a rotatable and axially slidable relation thereto, and a pair of cam followers 8a are rotatably supported on opposite sides of the bracket 8 by a shaft extending through the bracket 8 and the cam followers 8a.
  • the cam follower bracket 8 is rotatably supported on the shaft 1a, its movement is restricted by a guide pin 9 in such a way that it is slidable along the shaft 1a but not rotatable relative thereto.
  • An adjusting nut 10 is screwed on the free end of the surface roller shaft 1a, and a spring 11 is installed between the adjusting nut 10 and the cam follower bracket 8 for urging the cam 2 and the clutch plate 12 toward the clutch plate 3.
  • a shaft 13 having a pulley 14 secured at one end thereof is disposed below the end cam 2.
  • the pulley 14 is operatively connected to the end cam 2 by means of an endless belt 15.
  • a feeler lever 16 is slidably supported adjacent the other end of the shaft 13.
  • a stop plate 17 is fastened to the other end of the feeler lever shaft 13 by means of a bolt 18 and a stop ring 19 is fixed at an intermediate position on the shaft 13 by means of a set bolt 20, respectively, for restricting axial sliding movement of the feeler lever 16.
  • a spring 21 is installed between the feeler lever 16 and the stop ring 19 on the shaft 13 for urging the lever 16 against the stop plate 17.
  • the stop plate 17 has on its inner surface a rotation preventing pin 17a, while the feeler lever 16 has formed in its outer surface a reception hole 16a at such a position where the hole can be aligned with the pin 17a so that the latter can be received and fitted snugly in the former.
  • the feeler lever 16 is pressed against the stop plate 17 by the pressure of the spring 21.
  • the feeler lever 16 which is set in engagement with the cloth guide bar 22 with portion of the cloth W held therebetween is caused to be swung about the feeler lever shaft 13 with an increase of the diameter of the cloth roll 7.
  • the feeler lever 16 shown in FIG 2 is placed in its operative position for detecting the cloth roll diameter, where the shaft 13 is rotated with the swinging motion of the feeler lever 16 in an integral manner because the relative rotation preventing mechanism, comprising the pin 17a, hole 16a, stop plate 17, stop ring 19 and spring 21, is then in engaged condition.
  • the feeler lever 16 Because the pressure of the spring 11 acts on the feeler lever shaft 13 through the cam 2 and the cam followers 8 to rotate the shaft 13 in the direction reverse to the rotation during the normal operation, the feeler lever 16 will be swung back rapidly if the cloth roll 7 is removed from its winding position. To forestall such rapid swinging motion of the lever in removing the cloth roll 7 after completion of winding operation, firstly the feeler lever 16 is shifted away from its operative position of FIG 2 along the shaft 13 to a position shown in FIG. 3 where the pin 17a on the stop plate 17 is completely disengaged from the hole 16a in the lever. By so doing, only the feeler lever shaft 13 is rotated by the pressure exported by the expanding spring 11. Because rapid swinging of the feeler lever 16 can be thus avoided, removal of the cloth roll 7 from the loom dan be performed with ease and smoothness.
  • the feeler lever shaft 13 has a key 24 fixed thereto so that the feeler lever 16 is engaged with the shaft 13 by means of this key 24 during the normal winding operation so as to prevent the lever from rotating relative to its shaft.
  • the feeler lever 16 is shifted axially to be disengaged from the shaf t 13 so as to allow the shaft to be rotated independently of the feeler lever.
  • the dis engageable mechanism for preventing the relative rotation between the feeler lever and the feeler lever shaft can allow only the shaft to be rotated independently of the feeler lever by previously disengaging the relative rotation preventing mechanism by axially shifting the lever along its shaft, whereby rapid rotation of the feeler lever together with the shaft can be avoided and, therefore, the cloth roll removal from the laom can be facilitated.
  • a feeler lever 16 is supported on a feeler lever shaft 13 in a slidable relation thereto, and the range of sliding movement of the feeler lever 16 is restricted by a stop plate 17 and a stop ring 19.
  • the feeler lever 16 is urged toward the stop plate 17 by the pressure exerted by a spring 21.
  • the stop plate 17 has attached thereto a pin 17a, while the feeler lever 16 has formed therein a reception hole 16a.
  • the feeler lever 16 is normally positioned where the pin 17a is engaged with the hole 16a, but it is axially shifted to a position where, the pin 17a is moved out of the hole 16a when removing the wound-up cloth roll from the loom.
  • This axial shifting of the feeler lever 16 to disengage the pin 17a from the hole 16a allows only the feeler lever shaft 13 to rotate by the action of another spring 11 used for maintaining the cloth W at a constant tension during winding oparation, whereby rapid rotation of the feeler, lever 16 can be avoided during the removal of the cloth roll from the loom.
