Definitions

  • the present invention relates to a beating-up apparatus in looms, and more specifically, to an improved beating-up apparatus, which can excellently keep the rotational balance of a rocking shaft thereof.
  • a sley for supporting a reed is adapted to reciprocatingly swing in the forward and backward direction of a loom in response to the reciprocative rotation of a rocking shaft, whereby beating-up is carried out by the reed which swings integrally with the sley.
  • an oval-cylindrical shaft is engaged with a bearing pin (corresponding to the rocking shaft in the instant application) so that the center of weight of the shaft viewed from the longitudinal direction thereof is displaced from the center of rotation of the bearing pin to the side opposite to a sley.
  • the rocking shaft Since the rocking shaft is a long member whose length is near to the width of the loom, the rocking shaft also must be supported for rotation at the intermediate portion in the longitudinal direction thereof.
  • the oval-cylindrical shaft in the arrangement in which the oval-cylindrical shaft is engaged with the rocking shaft, the oval-cylindrical shaft must be machined to a circular shape to prevent the eccentric motion thereof at the intermediate portion where it is supported. Such machining is very troublesome.
  • an additional space is needed for the non-eccentric circular arrangement at the intermediate support position.
  • an object of the present invention is to provide an easily machinable and compact beating-up apparatus to overcome the above problem.
  • a beating-up apparatus in a loom including a sley, which is supported for swinging movement by a reciprocatingly rotatable rocking shaft through support means, is arranged such that an elongated counterweight is swingably disposed integrally with the rocking shaft on the side opposite to the sley in unison with the rocking shaft.
  • the elongated counterweight disposed on the side opposite to the sley corrects the rotational unbalance of the rocking shaft. Since the counterweight does not surround the entire periphery of the rocking shaft, the rocking shaft can be supported for rotation directly at the intermediate portion thereof in the longitudinal direction.
  • the size of the counterweight is approximately the same as that of the rocking shaft. At that time, the weight of the counterweight can be distributed uniform in the lengthwise direction with respect to the rocking shaft and an effect for preventing the twist of the rocking shaft is maximized.
  • the support means is a plurality of sley swords disposed in the lengthwise direction of the rocking shaft with intervals defined therebetween and the counterweight is coupled with the sley swords.
  • the long counterweight coupled with the sley corrects the rotational unbalance of the rocking shaft.
  • the counterweight coupled with the sley can be spaced apart from the rocking shaft, thus the rocking shaft can be rotatably supported directly at the intermediate portion in the longitudinal direction thereof.
  • each of the sley swords has through holes and a space defined therein, the rocking shaft and the counterweight being inserted through the through holes and the space causing the through holes to communicate with each other and providing the sley swords with flexibility and the rocking shaft and the counterweight are clamped under pressure by tightening means which extends passing through the sley swords across the space.
  • the long counterweight is clamped under pressure by the space of the plurality of sley swords. Therefore, no special member is necessary to mount the counterweight, thus the weight of the structure to be swung together with the rocking shaft is reduced.
  • the counterweight When the counterweight is composed of a single bar member, it can be simply mounted to the rocking shaft or the sley swords and the number of parts necessary to the mounting is reduced, thus this composition is preferable.
  • the rocking shaft, the counterweight and the slay are disposed in parallel with each other and the center of weight of a motion system including the slay and the counterweight which are swung integrally with the rocking shaft when the rocking shaft reciprocatingly rotates is located on the axial center of rotation of the rocking shaft.
  • the rocking shaft is supported by a bracket extending from a breast beam.
  • the counterweight may be directly coupled with the rocking shaft.
  • the counterweight may be an arc-shaped member mounted to the lower end portion of each of the sley swords so as to partially surround the lower end portion from the outside.
  • a through hole through which the rocking shaft is inserted is defined in each of the sley swords as well as a space communicating with the through hole is defined in the lower end portion of each of the sley swords and the sley swords are clamped and fixed to the rocking shaft as well as the counterweight is clamped and fixed to the respective sley swords by tightening means which extends passing through both the ends of the counterweight and the lower end portions of the respective sley swords across the space.
  • the counterweight may be mounted to the sley swords by fixing means which extends from the lower portion of the counterweight to the upper portion thereof and is threaded with the lower end portions of the sley swords.
  • FIGS. 1 to 3 A first embodiment embodying the present invention will be described based on FIGS. 1 to 3.
  • a rocking shaft 13 is supported for rotation between the right and left frames 11, 12 of a loom.
  • the rocking shaft 13 is reciprocatingly rotated by a not shown crank mechanism.
  • a breast beam 14 is disposed forwardly of the rocking shaft 13 and interposed between the side frames 11, 12.
  • a fell plate support mechanism for supporting the cloth fell of woven fabric from the lower side thereof, a temple device for preventing shrinkage of cloth and the like are supported by the breast beam 14.
  • a middle bracket 15 is fixedly mounted on the rear surface of the breast beam 14.
  • a presser 16 is tensioned and fixed on the top of the middle bracket 15.
  • the intermediate portion in the lengthwise direction of the rocking shaft 13 is rotatably supported between the middle bracket 15 and the presser 16.
  • a plurality of sley swords 17 are disposed in the lengthwise direction of the rocking shaft 13 and coupled therewith.
  • a pair of inserting holes 171, 172 are defined in each of the sley swords 17 and both the inserting holes 171, 172 communicate with each other through a slit 173.
  • the rocking shaft 13 is inserted through the inserting hole 171 and a single elongated counterweight 20 is inserted through the inserting hole 172 serving as tightening means.
  • Each sley sword 17 is clamped and fixed to the rocking shaft 13 by being tightened by a bolt 18 passing through the slit 173 and threadedly engaging with a nut 19. Further, the counterweight 20 is clamped to and coupled with each sley sword 17 by being tightened by the bolt 18 and the nut 19 constituting tightening means.
  • a sley 21 is fixedly mounted on the top of each sley sword 17 and a reed 22 extends upwardly from the sley 21.
  • the counterweight 20 is substantially as long as the rocking shaft 13.
  • the counterweight 20 is disposed on the side opposite to the sley 21 by a plurality of the sley swords 17 dispersed between the opposed ends of the rocking shaft 13.
  • the sley 21, the rocking shaft 13 and the counterweight 20 are disposed in parallel with each other so that the center of weight of them is located approximately on the axis of rotation of the rocking shaft 13 when viewed from the lengthwise direction thereof.
  • Sley swords 23 in the second embodiment are used only to support a sley 21 and a long counterweight 25 approximately as long as a rocking shaft 13 is directly tightened to and coupled with the rocking shaft 13 by screws 24.
  • a cutout 251 is formed in the intermediate portion of the counterweight 25 and a middle bracket 15 is inserted through the cutout 251.
  • the center of weight of the rocking shaft 13 and the counterweight 25 is located approximately on the axis of rotation of the rocking shaft 13 when viewed from the longitudinal direction thereof.
  • FIG. 5 a third embodiment shown in FIG. 5 will be described.
  • the same numerals as in the explanation for the first embodiment are used to designate the same components in the third embodiment.
  • the slit 262 communicates with an inserting hole 261 through which the rocking shaft 13 is inserted.
  • the semi-arc portion is engaged with a semi-arc-shaped counterweight 27 and a screw 28 is inserted through the counterweight 27 so as to be approximately perpendicular to the slit 262.
  • the counterweight 27 is bent or deformed so as to follow the inner side of the semi-arc portion of the counterweight 27 by being tightened by the screw 28 and a nut 29 to thereby narrow the gap of the slit 262 of the semi-arc portion of the sley sword 26.
  • the sley sword 26 is also clamped and fixed to the rocking shaft 13 by being tightened by the screw 28 and the nut 29.
  • the center of weight of the sley, the rocking shaft 13 and the counterweight 27 is located approximately on the axis of rotation of the rocking shaft 13 when viewed from the longitudinal direction thereof.
