Definitions

  • the present invention relates generally to a weft inserting apparatus for a rapier loom. More particularly, the invention is concerned with a weft feeding rapier head of a weft inserting apparatus which can ensure a smooth yarn guiding action.
  • a weft feeding head disclosed in Japanese Patent Laid-open No. 4-214439 (functionally corresponding to the weft feeding rapier head according to the present invention) is comprised of a base portion and a main body (functionally corresponding to a guide frame of the weft feeding rapier head according to the invention), wherein the main body includes a pair of side walls.
  • a gripper for holding a weft is fixedly secured to the base portion in such disposition that the weft guided along upper edges of the paired side walls can be introduced into a gripping portion of the gripper.
  • the gripper is constituted by a rigid clamp jaw equipped with a weft deflecting fin and a resilient tongue member, wherein the weft is held between the rigid clamp jaw and the resilient tongue member.
  • the tip end portion of the resilient clamp jaw is configured so as to guide the weft to the aforementioned gripping portion.
  • a weft guide (denoted by reference numeral 10 or 19) has to be indispensably provided in opposition to the rigid clamp jaw in order to realize the aimed operation or function.
  • the rigid clamp jaw provided with the weft deflecting fin is formed separately from the main body mentioned above. Consequently, difficulty is encountered in shaping the main body such that the weft guiding action performed by the upper edge of one side wall can be smoothly turned over to the weft guiding action performed by the tip end portion of the rigid clamp jaw.
  • the attempt for providing the weft guide in the side wall or a top wall member will encounter difficulty in properly shaping the edge of the side wall or the edge of the overhanging top wall, giving rise to a problem that weft breakage occurs due to excessive abrasion of the weft upon contacting with the warp and/or the loosened warp may find way to beneath the top wall, incurring ultimately breakage of the warp.
  • the present invention is directed to a weft inserting apparatus for a rapier loom, in which a weft feeding rapier head and a weft receiving rapier head each provided with a weft gripping means are inserted into a shedding formed by warps along a sley or a guide member disposed in a width direction of a woven fabric for transferring the weft from the weft feeding rapier head to the weft receiving rapier head, and then the weft feeding rapier head and the weft receiving rapier head are retracted from the shedding, to thereby effectuate weft insertion.
  • a weft feeding rapier head of the weft inserting apparatus which features that an outer wall of the weft feeding rapier head is constituted by a guide frame composed of a side wall located at the side of a reed, a bottom wall and a warp guiding top wall each extending from the side wall, and a vertically upstanding wall extending from the bottom wall and disposed at the side of a cloth fell with a predetermined distance from the side wall.
  • a vertically suspended wall for guiding the weft is disposed between the side wall and the vertically upstanding wall, wherein the vertically suspended wall is connected to the top wall and extends vertically downward toward the bottom wall. Further, a gripping mechanism for gripping the weft is disposed between the vertically upstanding wall and the vertically suspended wall.
  • a weft position regulating portion formed in a concave shape may be disposed above the bottom wall at the side of the reed.
  • a weft guiding edge portion may be formed at a lower end of the vertically suspended wall.
  • the weft guiding edge portion may be formed in a shape curved toward the reed from the lower end of the vertically suspended wall.
  • the guide frame and the vertically upstanding wall may be formed separately from each other, while a mounting member extending toward the bottom wall may be formed in the vertically upstanding wall, wherein the guide frame and the vertically upstanding wall may be integrally combined with each other by securing the bottom wall and the mounting member to each other.
  • the mounting member of the vertically upstanding wall may be disposed on an upper surface of the bottom wall of the guide frame and fixedly secured thereto.
  • the mounting member of the vertically upstanding wall may be disposed on a lower surface of the bottom wall of the guide frame and fixedly secured thereto.
  • a spacer may be interposed between the bottom wall of the guide frame and the mounting member of the vertically upstanding wall.
  • a flat surface forming plate may be mounted on a lower surface of the mounting member of the vertically upstanding wall or alternatively on a lower surface of the bottom wall of the guide frame disposed in opposition to the guide member or the sley disposed in the width direction of the woven fabric.
  • the guide frame composed of at least the side wall, the bottom wall and the top wall may be formed by bending and/or folding a single metal sheet.
  • the guide frame and the vertically suspended wall may be formed by bending and/or folding a single metal sheet.
  • the guide frame, the vertically suspended wall and the weft guiding edge portion provided at the lower end of the vertically suspended wall may be formed by bending and/or folding a single metal sheet.
  • the guide frame, the vertically suspended wall and the vertically upstanding wall may be formed by bending and/or folding a single metal sheet.
  • the guide frame, the vertically suspended wall, the weft guiding edge portion provided at the lower end of the vertically suspended wall and the vertically upstanding wall may be formed through a precision steel casting process or alternatively by resorting to a powder-metallurgical process.
  • the guide frame, the vertically suspended wall and the weft guiding edge portion provided at the lower end of the vertically suspended wall may be formed through a precision steel casting process or alternatively a powder-metallurgical process.
  • a mount base for the gripping mechanism may be formed integrally with the vertically upstanding wall or the mounting member of the vertically upstanding wall or across the vertically upstanding wall and the mounting member.
  • a portion of the top wall may be formed as a reinforcing protrusion.
  • a rapier band 11 is wrapped around a wheel (not shown), and a weft feeding rapier head generally denoted by reference numeral 12 is secured to a tip end portion of the rapier band 11 by means of screws so as to reciprocatively move into and out from a shed formed by warps T under reciprocative rotation of the wheel.
  • Figs. 2(a) and 2(b) in which Fig. 2(a) is a top plan view showing the weft feeding rapier head 12 and Fig. 2(b) is a side elevational view of the same.
  • the weft feeding rapier head 12 is generally comprised of a guide frame 13 and a gripping mechanism 14 which is secured to the guide frame 13.
  • Figs. 3(a) and 3(b) in which Fig. 3(a) is a front end view of the weft feeding rapier head 12 and Fig. 3(b) is a sectional view of the same taken along a line A-A shown in Fig.
  • the gripping mechanism 14 includes a stationary gripping member 141, a movable gripping member 142 which is resiliently deformable or flexible and a leaf spring 143 for resiliently urging the movable gripping member 142 onto the stationary gripping member 141.
  • the stationary gripping member 141, the movable gripping member 142 and the leaf spring 143 are fixedly stacked together in this order as viewed from the top, whereby a unitary assembly is formed, which is secured to the guide frame 13 by the screws.
  • the guide frame 13 is constituted by a bottom wall 15, a vertically upstanding wall 16 disposed erectly at one lateral side of the bottom wall 15 (i.e., at the side facing a cloth fell of a woven fabric), a sidewall 17 disposed erectly at the other side of the bottom wall 15 (i.e., at the side of a reed 20 on a sley 10), a top wall 18 extending continuously from the side wall 17 and disposed in opposition to the side wall 17 and a vertically suspended wall 19 extending vertically downwardly from the top wall 18.
  • Fig. 3(c) which shows the weft feeding rapier head in a sectional view taken along a line B-B in Fig.
  • the rapier band 11 is secured to a base portion of the bottom wall 15 by means of screws.
  • a mount base 151 mounted fixedly on the upper surface of the bottom wall 15 is a mount base 151 on which a gripping mechanism 14 is secured by means of screws.
  • a flat surface forming plate 21 is secured to the lower surface of the bottom wall 15.
  • the lower surface of the flat surface forming plate 21 lies flush with that of the rapier band 11, whereby there can be ensured smoothness in guiding a warp on and along the lower surface of the bottom wall 15 (see Fig. 3(a)).
  • the flat surface forming plate 21 can be made of synthetic resin materials or metal materials.
  • the vertically upstanding wall 16 has an upper edge which is formed continuously by a weft guiding edge portion 161 extending slantly upwardly from the leading end portion of the vertically upstanding wall 16, a weft guiding edge portion 162 extending obliquely downward from the weft guiding edge portion 161 and a weft guiding edge portion 163 extending substantially horizontal.
  • the upwardly sloped weft guiding edge portion 161 is also destined to serve as a weft guiding edge portion.
  • a weft guiding edge portion 191 is formed at the lower end of the vertically suspended wall 19. More specifically, the weft guiding edge portion 191 is bent or curved toward the side wall 17 from the lower edge of the vertically suspended wall 19. With the arrangement described above, the weft Y can be guided into a gripping portion defined between the stationary gripping member 141 and the movable gripping member 142 through cooperation of the weft guiding edge portions 161, 162, 163 and 191.
  • warp guiding edge portions 171 and 172 Formed in upper and lower edge portions of the side wall 17 at locations closer to the leading end thereof are warp guiding edge portions 171 and 172 which are gradually distanced from each other in the direction as viewed from the tip end of the side wall 17.
  • the side wall 17 serves as a guide for grouping the warps T into upper and lower warp layers (T) along the warp guiding edge portions 171 and 172 upon operation for forming the shedding.
  • the warp guiding action of the warp guiding edge portion 172 is succeeded by a front edge portion 152 of the bottom wall 15 and the bottom surface of the flat surface forming plate 21.
  • a slanted warp guiding surface 181 Formed in a tip end portion of the top wall 18 are a slanted warp guiding surface 181 and a forefront edge 184.
  • the warp guiding action performed by the warp guiding edge portion 171 is smoothly transferred to the warp guiding action of the warp guiding surface 181.
  • a concave-shaped weft guiding edge portion 173 which cooperates with the weft guiding edge portions 161 and 191 to guide the weft Y into the gripping portion of the gripping mechanism 14.
  • a weft position regulating recess 183 which serves as a means for regulating the position of the weft. The weft Y which is in the state gripped by the gripping mechanism 14 can thus be brought into contact with the weft position regulating recess 183. In this way, the path of the weft Y which is in the state held by the gripping mechanism 14 is regulated by the weft position regulating recess 183.

  • the warp T is guided upwardly at a location of the forefront edge 184, being regulated by the weft guiding edge portion 161 and the warp guiding edge portion 171, to reach the warp guiding surface 181.
  • the weft Y is guided downwardly at a location of the forefront edge 184 under regulation by the weft guiding edge portion 161 and the weft guiding edge portion 173 to reach the weft guiding edge portion 191.
  • the forefront edge 184 plays a role as a branching point for setting separately the directions in which the warps T and the weft Y are to be guided, respectively.
  • the weft feeding rapier head 12 which is gripping and carrying the weft Y encounters a receiving rapier head (not shown) substantially at a central position as viewed in the width direction of the woven fabric, whereby the weft Y gripped by the weft feeding rapier head 12 is transferred to the weft receiving rapier head arrived at a transfer position between the side wall 17 and the vertically suspended wall 19.
  • a vertically suspended wall 25 and a top wall 26 are formed integrally with each other as a unitary structure separately from the other guide frame forming portions.
  • the vertically suspended wall 25 and the top wall 26 are formed by bending correspondingly a metal sheet, wherein the top wall 26 is secured to a mounting member 185 formed integrally with the side wall 17.
  • the top wall 26 and the vertically suspended wall 25 may also be formed through a precision steel casting process typified by a lost-wax process, a sintering process, an injection molding process, a powder-metallurgical process such as an injection molding/sintering process or the like.
