Description

The present invention relates to frame steers, etc., which form part of a heald frame.

In many frame steves, the healds are attached to the heald rods with some play. Therefore, as the heald frame reciprocates while the loom is in operation, the healds move up and down relative to the heald rods. In this case, the healds' insertion points on the healds wear out as they repeatedly collide with the heald rods, and the healds may break in a short period of time. The heald rods also wear out, and the collisions generate noise. To solve these problems, dampers have been provided to cause the healds to collide with the heald rods before they collide.

Patent Document 1 describes a frame steve with a damper attached to a recess formed on the heald rod side (inside) of the hollow steve body. In this frame steve, a pair of walls that divide the recess into the front and back are each formed on their inner surfaces. Meanwhile, recesses are formed on both sides of the damper. The damper is supported by the frame steve with the pair of projections fitting into the recesses on both sides. In this specification, the terms "inside" and "outside" are used to refer to the open side of the frame shape when viewed from the front of the heald frame as the inside.

China Utility Model No. 205954196

In some looms, the height of the wall extending from the inner end of the steve body is designed based on the position of the slit in the drawing machine. In such cases, in the frame steve described in Patent Document 1, the distance from the recess in which the damper is attached to the heald rod is determined by the position of the slit in the drawing machine. If this distance is relatively long, the height of the damper is required, which results in the damper becoming larger.

The present invention was made in consideration of these circumstances, and aims to realize a frame Steve that allows the damper to be made smaller, regardless of the height of the wall portion extending from the inner end of the Steve body.

In order to solve the above-mentioned problems, the first invention is a frame steve that constitutes a part of a heald frame, and is provided with a hollow steve body, a wall portion that extends inward from the inner end of the steve body when the frame-shaped opening side is on the inside in a front view of the heald frame, a heald rod that is provided on one side of the wall portion and to which one end of the heald is attached, and a damper attachment portion that protrudes from one side of the wall portion and to which a damper that collides when the heald moves outward relative to the frame steve is attached.

The second invention is the first invention, in which a damper abutment plate is provided on one side of the wall portion, protruding from a position between the inner end face of the Steve body and the damper mounting portion, and abutting against the damper attached to the damper mounting portion.

The third invention is the second invention, in which the tip of the damper contact plate on the damper side when the damper is attached is exposed.

The fourth invention is the second or third invention, in which a convex portion is formed on the surface of the damper attachment portion facing the damper contact plate.

The fifth invention is any one of the second to fourth inventions, in which the Steve body has a hollow structure with the front and rear walls connected by multiple cross beams, the rear wall protrudes inward from the innermost cross beam, a recess is formed between the protruding part and the wall surface part into which a reinforcing member is inserted, and the distance in the vertical direction between the inner end of the rear wall and the damper abutment plate is approximately equal to the height of the reinforcing member.

The sixth invention is a heald frame equipped with a frame steer of any one of the first to fifth inventions.

The seventh invention is a loom equipped with the heald frame of the sixth invention.

An eighth aspect of the present invention is a damper that is attached to a damper mounting portion of a frame steel of any one of the first to fifth aspects of the present invention.
It is a damper.

In the present invention, the damper mounting portion to which the damper is attached protrudes from one side of the wall portion that extends inward from the inner end of the hollow Steve body. Therefore, the height of the damper is determined by the installation position of the damper mounting portion on the wall portion. Therefore, unlike the frame Steve described in Patent Document 1, it is possible to make the damper smaller regardless of the height of the wall portion.

The following describes in detail the embodiments of the present invention with reference to the drawings. Note that the following embodiments are examples of the frame steve and heald frame of the present invention, and are not intended to limit the scope of the present invention, its applications, or its uses.

[Outline of the heald frame configuration]
The heald frame 10 is a frame-shaped component used in a weaving machine. In the weaving machine, a plurality of heald frames 10 are moved up and down using a shedding device to produce a woven fabric. As shown in FIG. 1, the heald frame 10 includes a pair of frame steves 12 constituting the horizontal members (cross beams) of the frame, and a pair of side stays 14 constituting the vertical members of the frame. The pair of frame steves 12 are arranged at a distance from each other in the up-down direction (vertical direction). The pair of side stays 14 are arranged at a distance from each other in the left-right direction (horizontal direction). Each side stay 14 is connected at its upper part to the upper frame steve 12 and at its lower part to the lower frame steve 12.

In this embodiment, the pair of frame steves 12 have the same configuration. The pair of side stays 14 also have the same configuration. However, the pair of frame steves 12 may have different configurations, and the pair of side stays 14 may have different configurations. As described above, in this specification, the frame-shaped opening 11 side is defined as the inside when viewed from the front of the heald frame 10, and the terms "inside" and "outside" are used. The inside of the upper frame steve 12 means the "lower side," and the inside of the lower frame steve 12 means the "upper side."

[Frame Steve's Configuration]
Next, the frame Steve 12 will be described.

The frame steve 12 is formed by extrusion molding using metals such as aluminum alloys and stainless steel. In cross section, as shown in FIG. 2(a), the frame steve 12 has a hollow steve body 21, a wall portion 22 extending inward from the inner end of the steve body 21, and a heald rod 23 provided on the rear side (one side) of the wall portion 22 and to which one end of a plurality of healds 25 (see FIG. 1) is attached. As shown in FIG. 1, each heald 25 is hung between the heald rod 23 of the upper frame steve 12 and the heald rod 23 of the lower frame steve 12. Note that only some of the healds 25 are shown in FIG. 1.

In cross section, the Steve main body 21 includes a front wall 16, a rear wall 17 that is substantially parallel to the front wall 16, and multiple cross beams 18a-18c (three cross beams 18a-18c in this embodiment) that connect the front wall 16 and the rear wall 17 to each other. The Steve main body 21 has a hollow structure because the front wall 16 and the rear wall 17 are spaced apart from each other, and the multiple cross beams 18a-18c are spaced apart from each other. In the following, the outermost cross beam 18a (upper side in FIG. 2(a)) is referred to as the "first cross beam," the middle cross beam 18b as the "second cross beam," and the innermost cross beam 18c as the "third cross beam."

The side stays 14 are connected to the Steve main body 21 at each of the left and right ends by a connecting structure. The connecting structure has a plate-shaped protrusion 14b (see FIG. 4(a)) that protrudes from the side surface 14a on the opening 11 side of the side stay 14, and a stay holding portion (not shown) that holds the plate-shaped protrusion 14b in the internal space at the end of the Steve main body 21. The stay holding portion is fixed between the second cross beam 18b and the third cross beam 18c in the internal space of the Steve main body 21.

The wall portion 22 is a flat portion that extends straight from the front position on the inner end surface of the Steve body 21 to the inside of the heald frame 10. The wall portion 22 has a plurality of inspection windows 22a formed at equal intervals along the left-right direction. On the rear surface of the wall portion 22, as shown in FIG. 2(b), a rod support portion 31, a damper mounting portion 32, and a damper abutment plate 33 are provided in this order from the inside. Each of the rod support portion 31, the damper mounting portion 32, and the damper abutment plate 33 is provided over the entire length of the frame Steve 12 in the left-right direction. Note that FIG. 2(a) shows the state in which the damper 30 described later is attached, and FIG. 2(b) shows the state in which the damper 30 is removed.

The rod support part 31 is a part that protrudes slightly rearward from the lower part of the rear surface of the wall part 22. The heald rod 23 is fixed to the rear surface of the rod support part 31 by a fastener such as a rivet.

The heald rod 23 is formed in a long plate shape and is fixed to the rear surface of the rod support part 31 in an upright position with its width facing up and down. The heald rod 23 extends over the entire length of the frame steve 12 in the left-right direction.

Here, as shown in FIG. 1, the heald 25 is a rod-shaped part with a hole in the center through which the warp thread passes. At each end 25a of the heald 25, an insertion part 25b is formed through which the heald rod 23 passes. As shown in FIG. 3, the insertion part 25b is an elongated hole extending in the length direction of the heald 25, and has an open side. The height of the insertion part 25b is slightly greater than the height of the heald rod 23. Therefore, the heald 25 is attached to the heald rod 23 with a small amount of play.

The damper mounting portion 32 is a protrusion to which the damper 30 for the heald 25 is attached. The damper mounting portion 32 protrudes rearward from a position on the rear surface of the wall portion 22 that is closer to the Steve main body 21 than the center in the height direction. In a cross-sectional view, the damper mounting portion 32 is provided approximately perpendicular to the wall portion 22. At the tip of the damper mounting portion 32, a convex portion 32a is formed on the surface facing the damper abutment plate 33. Note that the convex portion 32a may be formed on the base side of the damper mounting portion 32 instead of at the tip, and multiple convex portions 32a may be formed.

Here, the damper 30 is a rod-shaped part made of a material that is elastically deformable and has cushioning properties (e.g., resin materials such as urethane and elastomer). When the damper 30 is attached to the damper attachment portion 32, it extends in the left-right direction of the frame steve 12 as shown in FIG. 1. The cross-sectional shape (transverse cross-sectional shape) of the damper 30 is the same along the length. As shown in FIG. 2(b), the cross-sectional shape of the damper 30 is slightly vertically elongated and has a substantially rectangular shape with one corner cut out. When attached, the cutout portion 30b is located on the opposite side of the wall portion 22 in the front-rear direction and on the damper abutment plate 33 side in the up-down direction. Note that the damper 30 portion is hatched in FIG. 1.

The damper 30 is formed with a protrusion receiving portion 36 into which the damper mounting portion 32 is fitted. The protrusion receiving portion 36 is a horizontal hole extending in the width direction of the damper 30 from one side surface of the damper 30 (the right side surface in FIG. 2(b)). The protrusion receiving portion 36 is formed at a position closer to one end than the center in the vertical direction (closer to the top in FIG. 2(b)). The protrusion receiving portion 36 is formed in a shape corresponding to the cross-sectional shape of the damper mounting portion 32. Specifically, a recess 36a having a shape corresponding to the convex portion 32a is formed at one end side on the rear side of the protrusion receiving portion 36. The protrusion receiving portion 36 is formed over the entire length of the damper 30 in the longitudinal direction. The damper 30 may be attached to the damper mounting portion 32 at the manufacturing factory of the heald frame 10, or may be attached to the damper mounting portion 32 by a user of the loom at the factory where the loom is installed.

Figure 3(a) shows the timing when the heald 25 moves slightly upward (in the direction of the bold arrow) relative to the frame steve 12 after the lower end of the heald 25 collides with the damper 30 attached to the lower frame steve 12. At this timing, the upper end P of the heald 25 is separated from the damper 30 attached to the upper frame steve 12.

When the heald 25 moves further upward from the state shown in FIG. 3(a), as shown in FIG. 3(b), the upper end P of the heald 25 collides with the damper 30 of the upper frame Steve 12 just before the outer end R of the lower insertion part 25b (long hole) of the heald 25 contacts the outer end Q of the heald rod 23 of the lower frame Steve 12. Also, when the heald 25 moves downward from this state, the lower end of the heald 25 collides with the damper 30 of the lower frame Steve 12 just before the outer end R of the upper insertion part 25b of the heald 25 contacts the outer end Q of the heald rod 23 of the upper frame Steve 12. Therefore, wear of the insertion part 25b in the heald 25 can be suppressed, and damage to the heald 25 can be suppressed. In addition, noise due to wear and collision of the heald rod 23 can also be suppressed.

The width X (see FIG. 2(b)) of the end face 30c of the damper 30 on the side of the damper abutment plate 33 is equal to or less than the width (projection length) of the damper abutment plate 33. In this embodiment, as shown in FIG. 3(a), the width X of the end face 30c is shorter than the width of the damper abutment plate 33. When the damper 30 is attached, at least the tip side of the surface of the damper abutment plate 33 on the damper 30 side is exposed. Therefore, when the damper attachment part 32 is fitted into the protrusion receiving part 36 during attachment of the damper 30, the damper abutment plate 33 projects rearward from the damper 30. Therefore, when the damper 30 is pushed into the wall part 22 side from this state using a roller, the roller can be moved along the lower surface of the tip side of the damper abutment plate 33 to push the damper 30, so that the workability of this pushing operation is good.

The damper abutment plate 33 is formed in a flat plate shape and protrudes rearward from a position between the inner end surface of the Steve main body 21 and the damper mounting portion 32 on the rear surface of the wall portion 22. In this embodiment, the damper abutment plate 33 protrudes from near the inner end surface of the Steve main body 21. The damper abutment plate 33 is disposed near the outer side of the damper mounting portion 32 so as to abut against the damper 30 attached to the damper mounting portion 32. The damper abutment plate 33 protrudes at least to, for example, directly above the held rod 23 (directly above the center position in the front-rear direction). In a cross-sectional view, the damper abutment plate 33 is disposed approximately perpendicular to the wall portion 22.

In this embodiment, by providing the damper abutment plate 33, even if a large number of healds 25 collide with the damper 30 at the same time, the damper 30 is prevented from moving outward, and the damper 30 can be prevented from coming off the damper mounting part 32. In addition, since the convex part 32a of the damper mounting part 32 is provided on the damper abutment plate 33 side, the damper 30 is more tightly restrained by the damper mounting part 32 and the damper abutment plate 33, making it less likely to come off the damper mounting part 32.

[Side stay configuration]
Next, the side stays 14 will be described.

As shown in FIG. 1, the side stay 14 is a rod-shaped part extending in the vertical direction. In a cross-sectional view, the outer peripheral shape of the side stay 14 is approximately rectangular. The thickness of the side stay 14 changes in the span section between the lower end of the connection point to the upper frame stay 12 and the upper end of the connection point to the lower frame stay 12. In the span section, the thickness of the side stay 14 becomes thinner as it approaches the center in the vertical direction. In the span section, the side surface 14a on the opening 11 side of the side stay 14 is formed into an arch-shaped curved surface that is convex in the opposite direction (outward) to the opening 11. The arch-shaped side surface 14a of the side stay 14 on the opening 11 side is slightly away from the end of the heald rod 23 (the left end in FIG. 4(a)). The side stay 14 may have a constant thickness in the length direction.

As shown in Fig. 4(a), the arched side 14a is provided with a stay-side projection 24 as a slip-out prevention structure to prevent the heald 25 from slipping out of the end of the heald rod 23. The stay-side projection 24 is, for example, a flat projection. The stay-side projection 24 protrudes laterally from the arched side 14a and extends slightly toward the center beyond the end of the heald rod 23 when viewed from the front of the heald frame 10. In addition, the position of the stay-side projection 24 in the front-rear direction is approximately the center of the arched side 14a at the base, as shown in Fig. 4(b), and faces the heald 25 at the tip.

Here, when the heald frame 10 is reciprocated, in the side stay 14, stress is concentrated on the opening 11 side of the plate-shaped protrusion 14b (the location of the thick arrow in FIG. 4(a)). In addition, according to a structural analysis, it was found that when the stay-side protrusion 24 is provided on the arched side surface 14a, stress is also concentrated near the stay-side protrusion 24 in the side stay 14. Therefore, if the stay-side protrusion 24 is installed near the plate-shaped protrusion 14b, stress on the opening 11 side of the plate-shaped protrusion 14b will increase. Therefore, in this embodiment, as shown in FIG. 4(a), the installation position of the stay-side protrusion 24 on the arched side surface 14a is separated from the plate-shaped protrusion 14b and is located inside the inner end 12a of the frame stay 12 in the vertical direction. This makes it possible to suppress the increase in stress on the opening 11 side of the plate-shaped protrusion 14b.

More specifically, the installation position of the stay-side projection 24 on the arched side surface 14a is in the range inside the inner end 12a of the frame steve 12 in the vertical direction, near the inner end 12a. The tip of the stay-side projection 24 is located in the height range of the end 25a of the heald 25 (the range from the outer end to the inner end of the end 25a when the heald rod 23 is in the middle of the height direction of the insertion part 25b). The end 25a of the heald 25 refers to the part outside the end Z of the linear part 25c with a constant thickness, and includes the part where the heald 25 is tapered. In the heald 25, the thickness (dimension in the front-rear direction) of the end 25a is larger than that of the linear part 25c, so the stay-side projection 24 can reliably prevent the heald 25 from falling off.

[Effects of the embodiment]
In this embodiment, the damper mounting portion 32 to which the damper 30 is attached protrudes from the rear surface of the wall portion 22 of the frame steve 12. Therefore, the height of the damper 30 is determined by the installation position of the damper mounting portion 32 on the wall portion 22. Therefore, unlike the frame steve described in Patent Document 1, it is possible to reduce the size of the damper 30 regardless of the height of the wall portion 22.

In addition, in the frame Steve described in Patent Document 1, a pair of wall projections fit into recesses on both sides of the damper over the entire length of the damper. To mount the damper in this state, it is necessary to move the damper laterally from one end of the frame Steve in the lateral direction (left-right direction) and insert the damper into the recessed portion described above. However, the frame Steve has a large lateral dimension, and mounting the damper is time-consuming. In contrast, in this embodiment, the damper 30 can be moved forward from the side of the wall portion 22 and attached to the damper mounting portion 32, making it easier to mount the damper 30.

In addition, in the frame steve described in Patent Document 1, in order to move the damper smoothly in the lateral direction when a pair of wall protrusions are inserted into the recesses on both sides of the damper during the installation work, the damper is designed to have a slight gap (backlash) between the recesses and protrusions. Therefore, when the heald frame moves up and down, the damper also swings up and down, and there is a risk that the insertion part of the heald and the heald rod will come into contact with each other slightly, causing wear. In contrast, in this embodiment, since the installation direction of the damper 30 is the front-rear direction, there is no need to provide backlash between the protrusion receiving part 36 of the damper 30 and the damper mounting part 32. The damper mounting part 32 can be designed to be in close contact with the protrusion receiving part 36 of the damper 30, and the vertical swing of the damper 30 can be suppressed when the heald frame 10 moves up and down, and wear of the insertion part 25b of the heald 25 and the heald rod 23 can also be suppressed.

[Modification of the embodiment]
In this modification, as shown in Figs. 5(a) and 5(b), reinforcing members 41, 42 for increasing the rigidity of the heald frame 10 are provided on the outer and inner sides, respectively, of the Steve body 21.

Specifically, on the outside of the Steve main body 21, the front wall 16 and the rear wall 17 protrude outward from the first cross beam 18a to form an outer recess 19 into which a rod-shaped first reinforcing member 41 is inserted. The outer recess 19 is defined by the front wall 16, the rear wall 17, and the first cross beam 18a, and is formed over the entire length of the Steve main body 21 in the left-right direction. The first reinforcing member 41 is fixed to the Steve main body 21 by adhesive applied to the defining surface of the outer recess 19.

Inside the Steve main body 21, the rear wall 17 protrudes inward from the third cross beam 18c, and an inner recess 20 is formed between the protruding portion and the wall surface 22, into which a rod-shaped second reinforcing member 42 is inserted. The inner recess 20 is defined by the rear wall 17, the wall surface 22, and the third cross beam 18c, and is formed over the entire length of the Steve main body 21 in the left-right direction. The second reinforcing member 42 is fixed to the Steve main body 21 by adhesive applied to the defining surface of the inner recess 20.

The material of each reinforcing member 41, 42 is, for example, carbon fiber composite material (CFRP: Carbon Fiber Reinforced Plastic), which is lighter than the material of the frame steve 12. The cross-sectional shape of each reinforcing member 41, 42 is a slightly vertically elongated rectangular shape. Each reinforcing member 41, 42 is used when the reciprocating motion of the heald frame 10 in the loom is high speed. Depending on the reciprocating motion speed, both the first reinforcing member 41 and the second reinforcing member 42 may be used, only one of them may be used, or neither may be used.

The distance D (see FIG. 5(b)) between the upper surface of the damper abutment plate 33 and the inner end (tip) of the rear wall portion 17 in the vertical direction is equal to or greater than the height of the second reinforcing member 42 so that the second reinforcing member 42 can be inserted into the inner recess 20. In this modified example, the smaller the height of the wall portion 22, the more the durability of the heald frame 10 improves, so the distance D is set to be approximately equal to the height of the second reinforcing member 42.

In this modified example, the height of the wall portion 22 is greater than in the above-described embodiment in order to attach the second reinforcing member 42 to the frame steve 12. However, even in such a case, a small damper 30 can be used regardless of the height of the wall portion 22.

In this modification, it is possible to reduce the height of the wall surface portion 22 compared to the embodiment. Therefore, it is possible to reduce the weight of the heald frame 10 and further improve the durability of the heald frame 10.

[Other embodiments]
In the above embodiment, the damper abutment plate 33 may be omitted as shown in Fig. 6(a). In this case, the convex portion 32a of the damper mounting portion 32 may be provided on the Steve body 21 side as in the above embodiment, or on the heald rod 23 side as shown in Fig. 6(a). Also, as shown in Fig. 6(b), the damper 30 attached to the damper mounting portion 32 may abut against the inner end surface of the Steve body 21.

In the above-described embodiment, the width X of the end face 30c of the damper 30 may be greater than the width of the damper abutment plate 33.

In the above embodiment, the damper mounting part 32 has a convex part 32a only on the damper abutment plate 33 side, but a convex part 32a may also be provided on the opposite side, the heald rod 23 side. Also, the convex part 32a may not be provided on the damper abutment plate 33 side, and may be provided only on the heald rod 23 side. Also, the damper mounting plate 32 may be a flat plate without a convex part.

In the above embodiment, the damper mounting portion 32 is provided substantially perpendicular to the wall portion 22, but it may be provided at an angle to the wall portion 22. In this case, for example, the damper mounting portion 32 may be provided at an angle so that the tip side of the damper mounting portion 32 approaches the heald rod 23 side.

In the above embodiment, the dampers 30 are attached to both the upper and lower frame steves 12, but the dampers 30 may be attached to only one of the frame steves 12 (e.g., the upper frame steve 12).

The present invention is applicable to frame steves etc. that are equipped with dampers for healds.
