Description

  [Technical Field] The present invention relates to a reed used for driving up and down warp yarns in order to form an opening between warp yarns into which weft yarns are inserted in a weaving process. The rod is made by bending and joining linear materials such as wire and yarn, and forming a wire rod with a fine dotted circular cross-sectional shape, and flat materials such as metal plates, bamboo plates, and plastics. There is a thin plate type punch formed by cutting and punching and having a flat cross-sectional shape. The present invention is the latter, i.e., the upper and lower ends of the shaft rod, which has a flat cross-sectional shape and is elongated, respectively, continue to the locking portion for locking to the locking rod for fixing to the rod frame, The present invention relates to a thin plate type scissor in which a mesh for inserting a warp is formed in an intermediate portion of a shaft scissor between an upper end locking portion and a lower end locking portion.

The shaft rod is twisted in the circumferential direction around the shaft center between the upper locking portion and the mesh and between the lower locking portion and the mesh. A thin plate type scissor is known in which the side surface on the mesh side of the shaft shaft and the side surface on the side of the locking portion continuing from the twisted portion form a required twist angle (see, for example, Patent Document 1). It is also known to provide unevenness on the side surface of the locking portion of the thin plate-type ridge (see, for example, Patent Documents 1 and 2). It is also known to make a thin plate mold by punching a metal material or fiber reinforced plastic (for example, see Patent Document 2). The locking rod for fixing the rod to the rod frame generally has a narrow flat plate shape, and the locking portion of the rod has a hook-shaped notch such as J-shape or C-shape, a long hole, etc. An engaging portion having a shape that fits with the collar is attached (see, for example, Patent Document 2).
Japanese Patent Laid-Open No. 7-252754 (FIG. 4) JP 2001-40543 A (paragraph [0012], paragraph [0028], FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 7, FIG. 8, FIG. 9)

  Since the hook is fixed to the hook frame with the thickness direction of the locking portion directed in the width direction of the loom, the mesh is also directed in the width direction of the loom. On the other hand, the warp yarn is applied to the loom with its length direction oriented in the depth direction of the loom, that is, in the direction perpendicular to the rib frame. Therefore, the warp thread inserted into the mesh and applied to the loom changes the direction of 90 degrees from the depth direction of the loom to the width direction of the loom at the mesh to be inserted, and again from the width direction of the loom to the depth direction of the loom. The direction will be changed by 90 degrees. For this reason, in the weaving process, the warp and the mesh are rubbed and easily worn. Providing a twisted part in which the shaft collar is twisted between the upper locking part and the mesh and between the lower locking part and the mesh reduces the friction between the warp and the mesh and wears them. This is to alleviate the problem. The twist angle (α) of the shaft rod at the twisted portion is set to 30 ° to 45 °, approximately 35 °, and the twisted portion has a shape protruding like a screw thread.

  The opening formed between the warps for inserting the wefts is formed by a set of two warps inserted through at least two kinds of reeds each having a different lifting movement, and each of the two sets of one set The warp passes through the side of the heel through which the other one warp is inserted and is led to the front of the weave. For this reason, each set of two warps is rubbed against the side surface of the heel through which one of the other warps is inserted in the opening movement.

  In the warp opening movement, the heel is driven up and down by at least 2 cm from the closed state of the opening. As a result, each pair of kites moves up and down relative to the other kite by 4 cm or more. By the way, in the conventional thin plate-type scissors, the twisted portion is set at a position very close to the scissors like the wire-shaped scissors formed by bending the wire. The warp yarn passing through the side surface of the cocoon inside is rubbed against the twisted portion of the cocoon passing therethrough. For this reason, in the weaving process of a high-density fabric with a dense warp density, the warp is rubbed against the torsion part and becomes fluffed, worn and easily broken (yarn breakage), not only causing a decrease in weaving efficiency but also quality. It becomes difficult to obtain a high-quality high-density fabric.

  The tenth feature of the thin plate-type scissors according to the present invention is in addition to any one of the first, second, third, fourth, fifth, sixth, seventh, eighth and ninth features. The thickness (r) of the locking portion 12 is thicker than the thickness (s) of the shaft rod 13.

  The eleventh feature of the thin plate-type scissors according to the present invention is any one of the first, second, third, fourth, fifth, sixth, seventh, eighth, ninth and tenth features. In addition, the locking portions 12 and 12 and the shaft rod 13 are integrally formed of acetal resin.

  In the thin plate type scissors of the present invention, the distance (L) from the mesh 16 to the twisted portion 17 is 40 mm or more, and the warp is not rubbed against the twisted portion 17 in the opening motion, and the warp in the weaving process. The inconvenience that 15 is rubbed against the twisted portion 17 and causes fluff or thread breakage is avoided.

  In the thin plate type cage of the present invention, the thickness (t) of the mesh portion 22 in which the mesh 16 of the shaft rod 13 is formed has a continuous portion 23 of the shaft rod 13 extending from the mesh 16 to the twisted portion 17. The width (m) of the mesh is reduced by the amount (s−t) where the thickness (t) of the mesh portion is thinner than the thickness (s) of the continuous portion (s−t). It can be narrowed. That is, when the thickness of the mesh portion is t and the thickness of the warp 14 inserted through the mesh is f, the shaft rod 13 has a required twist angle (α) at the twist portion 17 and the locking portion 12 FIG. 5 shows when the lateral width m of the square of the collar 24 twisted is set by the calculation formula; m≈ (f + t) × cot (α), as is apparent with reference to FIGS. The warp yarn 14 can pass through the mesh 16 without being particularly rubbed against the side edges 25, 25 of the mesh.

  Therefore, when the thickness (t) of the mesh portion is reduced, the lateral width (n) of the shaft can be reduced. And when narrowing the horizontal width (n) of the shaft rod, the gap (e) between the adjacent shaft rods is widened by the narrowed portion, so that it is not inserted into those meshes, and the gap between the adjacent rods The warp yarns 15 passing only through the yarns 24a and 24b are not particularly rubbed against the ridges 24a and 24b, and fuzz and yarn breakage of the warp yarns 15 are avoided. At the same time, the gap (y) between the locking portions 12 and 12 of the adjacent rods is narrowed by the width (n) between the adjacent shaft rods becoming wider by narrowing the lateral width (n) of the shaft rods, The warp density (wrinkle density) can be set precisely, and a high-density fabric can be woven without difficulty.

  In the thin plate type scissors according to the present invention, the side surface 18 of the locking portion 12 is bent in the thickness direction W of the locking portion 12 that is separated from the shaft core (M) of the bag passing through the upper and lower locking portions 12 and 12. When the hooks 24, 24, 24... Are attached to the locking hook 11 by alternately changing the direction of the inflection direction, the locking portions 12 and the locking portions of the adjacent hooks 24 a and 24 b due to the difference in the orientation. 12 is formed between the gaps 12 (FIG. 2-b). For this reason, when applied to the water jet loom, water accumulates between the locking portions 12 and 12, and the locking portion 12 and the locking portion 12 are brought into close contact with each other by the surface tension of the water. The intervals (e) are irregular, and the inconvenience that warp density unevenness occurs in the woven fabric is avoided.

In order to make it easy to insert the locking rod 11 into the engaging portion 27 of the locking portion, the height (internal dimension: k) of the engaging portion 27 is made higher than the height (external dimension: h) of the locking rod 11. In the case where the distance is slightly increased, there is a slight gap between the engagement portion 27 and the locking rod 11. However, when the side surface 18 of the locking portion 12 is bent in the thickness direction W as in the present invention, the locking portion 12 is inclined in the state where it has been inserted through the locking rod 11, and the angle θ is inclined. The height (h) of the engaging portion 27 in the height direction (k) of the locking rod 11 is shortened. That is, assuming that the inclination angle is θ, the height (h ′) of the inclined engaging portion 27 is h ′ = h × cos (θ) <h, so that the engaging portion 27 and the locking rod 11 are The close contact is avoided and play (backlash) between them is avoided.
In FIG. 2-b, the shaft rods 13 and 13 of the adjacent rods are in close contact, but FIG. 2-b clearly shows the fact that a gap 26 is formed between the locking portions 12 and 12. Yes, it does not indicate that the adjacent shaft rod 13 and the shaft rod 13 are in close contact.

  In the thin plate-type scissors according to the present invention, the distance (g) from the shaft core (M) passing through the upper and lower locking portions 12 and 12 to the side edge 19 on one side of the shaft rod 13, and the shaft core of the kite Since the distance (d) from (M) to the side edge 20 on the other side of the shaft rod 13 is different, the direction of the shaft rod in the width direction (n) is changed alternately to make the rods 24, 24, 24. When... Is attached to the locking rod 11, the adjacent shaft rod 13 and the shaft rod 13 do not face the entire surface, and the warp 15 can pass through without difficulty.

  In particular, the distance (g) from the shaft core (M) passing through the upper and lower locking portions 12 and 12 to the side edge 19 on one side of the shaft rod 13 is from the shaft core (M) of the shaft 13 to the shaft rod 13. The side shaft 19 on one side of the shaft rod 13 which is shorter than the distance (d) to the other side edge 20 and shorter in distance (g), and the shaft of the shaft passing through the upper and lower locking portions 12 and 12 A shallow recess 21 corresponding to the distance (g) reaching the short side edge 19 is formed between the core (M) and the recess 21 is vertically connected along the shaft core (M) of the bag. In the reed that continues to the stop portions 12 and 12, a gap 30 is formed between the adjacent reeds 24a and 24b (FIGS. 2-a and 5), and the warp yarn 15 passing between them is formed on the side edge 19 of the shaft reed. Inconveniences such as fluffing and thread breakage are avoided.

  Accordingly, the collar 24 having at least two of the first, second, third and fourth characteristics, or at least two of the first, second, third and fifth characteristics, According to the kite 24 having all the first, second, third and fifth features, the intended effect of the present invention can be exhibited without regret.

  When the thickness (r) of the locking portion 12 is made larger than the thickness (s) of the shaft rod 13 so that the thickness of the rod 24 gradually increases from the twisted portion 17 along the shaft core R of the shaft rod, The tension acting along the shaft core R of the flange 13 does not return torsion (α) at the torsion portion 17, and the shape of the shaft flange 13 twisted with respect to the locking portion 12 is stably maintained, which is durable. A cocoon 24 with the following is obtained.

In the present invention, since plastic is applied to the flange 24 and the flange 24 is formed by injection molding, the twist angle (α) of the twisted portion 17, the inclination angle (θ) of the locking portion 12, the continuous portion 23, The accuracy of the thickness difference (dt) between the mesh portion 22 is ensured, and a thin plate-type cage 24 suitable for a high-density fabric is obtained.
In addition, as a plastic, an acetal resin is optimal in terms of wear resistance against warp and water resistance when applied to a water jet loom, and the thickness (s, t) of the shaft 13 should be 1 mm or less. I can do it.

The width n of the shaft rod 13 is 2 to 3 mm, preferably 2 mm to 2.5 mm.
The distance (L) from the mesh 16 to the twisted portion 17 is 40 mm or more, and the side surface 18 of the latching portion 12 is separated from the shaft core (M) of the collar passing through the upper and lower latching portions 12 and 12. When the hooks 24, 24, 24... Bent in the thickness direction W of the portion 12 are sequentially attached to the locking rod 11 by alternately changing the direction of the inclination (θ) of the locking portion 12, A gap 26 is formed between the engaging portions 12 and 12 (FIG. 2-b), and a gap (e) corresponding to the thickness (f) of the warp 15 is surely provided between the adjacent shaft collars 13 and 13. In order to form the ridges (FIG. 5), it is preferable to prepare a pair of ridges 24a and 24b in which the twist directions (α) in the twisted portion 17 are opposite to each other.

  Similarly, the distance (L) from the mesh 16 to the twisted portion 17 is 40 mm or more, and the side edge 19 on one side of the shaft 13 from the shaft core (M) passing through the upper and lower locking portions 12, 12. Is shorter than the distance (d) from the shaft center (M) of the shaft to the other side edge 20 of the shaft 13, and the shaft 13 has a short distance (g). A shallow recess 21 corresponding to the distance (g) reaching the short side edge 19 is formed between the side edge 19 on one side and the shaft core (M) passing through the upper and lower locking portions 12 and 12. , And the recesses 21 that continue to the upper and lower locking portions 12, 12 along the shaft axis (M) of the heel 24, 24, 24. When the direction of θ) is alternately changed and is sequentially attached to the locking rod 11, the gap 30 corresponding to the thickness (f) of the warp 15 is provided between the adjacent shaft rods 13 and 13 (FIG. 2-a). In order to ensure that the gap (e) (FIG. 5) is formed (FIG. 2-a), a pair of flanges 24a and 24b whose twist directions (α) in the twisted portion 17 are opposite to each other are provided. Prepare it.

The width of the gap 30 formed between the shaft rods of the pair of rods 24a and 24b may be 2 mm or less (FIG. 5). Specifically, the distance (g) from the shaft core M of the rod to the side edge 19 of the rod may be 1 mm or less, or 0.2 to 0.5 mm.
The engaging portion 12 of the locking portion 12 that engages with the locking rod 11 can be a long hole as shown in FIGS. 4-a and 4-c, and is also shown in FIG. 4-b. It can also be made into a bowl-shaped notch (see FIG. 4 of Patent Document 1 and FIGS. 1 to 9 of Patent Document 2).

  In a bag applied to the water jet loom, in order to avoid the close contact due to the surface tension of water between the adjacent locking portions attached to the locking rod 11, it is illustrated in FIGS. As described above, the width (a) of the left side surface 28a and the width (b) of the right side surface 28b of the engaging portion are changed so that one side surface protrudes from the other side surface between adjacent locking portions. 29 can be provided on one side surface 28b of the locking portion 12, and a protrusion or an unevenness is provided on the side surface of the locking portion 12 so that the adjacent locking portions 12 and 12 do not come into surface contact, that is, the protrusion. It is also possible to make a point contact through the unevenness.

However, when the twisted portion 17 is provided at a position close to the locking portion 12, the twisted portion 17 has a shape that is twisted and raised on the side surface, and serves as a means for avoiding the close contact between the locking portions 12.
Considering this point, a position closer to the locking portion 12 than the mesh 16 and a position where the distance (z) from the engaging portion 27 becomes 30 mm or less, preferably around 20 mm (20 ± 5 mm). It is recommended to set the torsion part 17 at a position.
The thickness r of the engaging portion 12 that continues from the twisted portion 17 along the axis R of the shaft rod 13 is s, the thickness of the shaft rod 13 is n, and the torsion at the torsion portion 17 is n. When the angle is α, it may be set as r = s + n × sin (α). That is, the thickness r of the locking portion 12 is made equal to the width (x) of the shaft 13 projected in the length direction of the warp 14 (15) set on the loom (FIG. 5).

  The torsion part 17 is set at a position close to the locking part 12, and in the water jet loom, the contact between the adjacent locking parts (12, 12) mounted on the locking rod 11 and avoided due to the surface tension of water is avoided. When the twisted portion 17 is used as a means, the position (z) of the twisted portion 17 of the adjacent heel may be changed in order to prevent the twisted portion 17 of the adjacent heel from touching.

  If the position (z) of the twisted portion 17 of the pair of ridges (24a, 24b) having different twist directions is changed, the difference in the twist direction, that is, the two types of pairs of ridges (24a, 24b) Differences in types can be identified by differences in the positions (z) of the twisted portions 17, and the differences can be alternately mounted on the locking rods 11 one after another without mistakes. Convenient.

  In the present invention, the side surfaces P and Q of the shaft rod, the side surface 18 of the locking portion, and the side surface 18 of the engaging portion are the axes projected in the length direction of the warp set on the loom. When the surface of the rod is a front view, it means the surfaces of the shaft rod, the locking portion, and the engaging portion projected on the left and right side views corresponding to the front view.

It is a perspective view of the bag concerning the present invention, and encloses and expands and shows a part. It is a related figure of the front (Drawing 2-b and Drawing 2-c) and the side (Drawing 2-a) of the bag concerning the present invention.
