The larger the opening amount of the warp-wetting warp, the more easily the weft of the weft yarn is carried out. In the apparatus disclosed in Patent Literature 1, it is necessary to increase the radius of rotation of the lever (that is, the distance from the center of rotation of the lever to the connection position of the lever and the link) to increase the opening amount of the largest dietary warp warp. . Increasing the radius of rotation of the lever increases the torque required to rotate the lever and increases the load on the electric motor. This makes it difficult to operate the electric motor at high speed, which hinders the speed of the loom.

An object of the present invention is to provide a dietary forming apparatus which can increase the amount of opening of a dietary warp warp without disturbing the speed of the loom.

It extends upwards between the opposing surfaces 201 of 20.

A plurality of power receiving holes 231 and 241 are formed in the first band 23 and the second band 24. A power transmission tooth 181 meshes with the power receiving holes 231 and 241. That is, the first band 23 and the second band 24 are deflected so as to engage the power receiving holes 231 and 241 and the power transmission tooth 181 of the first band 23 and the second band 24. In this state, the wheels 18 are opposed to each other.

In the engagement position of the power receiving hole 231 of the first band 23 and the power transmission tooth 181, the facing surface 191 (guide plane 194) of the first positioning regulator 19 is provided with an escape groove ( 192 is formed.

The heald 12 is latched. That is, the 1st band 23 supports the 1st preparatory warp heald, and the 2nd band 24 supports the 2nd preparatory warp heald.

Next, the operation of the first embodiment will be described.

The output shaft 171 of the electric motor 17 reciprocates, and the wheel 18 reciprocates. Reciprocating rotation of the wheel 18 is transmitted to the first band 23 and the second band 24 through the engagement of the power transmission tooth 181 and the power receiving holes 231, 241. Thereby, the 1st band 23 and the 2nd band 24 drive up and down inside guide grooves 221, 222 mutually. The first band 23 reciprocates in sliding contact with the opposing surface 191 (guide curved surface 193 and guide plane 194) as a guide surface, and the second band 24 is opposing surface 201 as a guide surface; The guide curved surface 203 and the guide plane 204 are in sliding contact with the reciprocating drive. That is, the first position regulator 19 is in contact with the first band 23 to regulate the engagement position of the first band 23 and the wheel 18, and the second position regulator 20 is connected to the second band ( Abut the second band 24 to regulate the engagement position of the wheel 18 with the wheel 24.

When the first band 23 and the second band 24 drive up and down inside the guide grooves 221, 222 in opposite directions, the first dietary warp heald heald 11 and the second dietary warp heald ( 12) moves up and down in opposite directions. Thereby, the dietary warp yarn 14 (refer FIG. 1) passed through the 1st dietary warp heald heald (11), and the dietary warp warp (15; FIG. 1) which passed through the 2nd dietary warp heald. The interposed weft yarn (not shown) is sandwiched between them to form an expression (We; see FIG. 1).

The guide rail 22 is a third position regulator having a pair of guide grooves 221 and 222 which guide in parallel to each other. The first position regulator 19, the second position regulator 20 and the guide rail 22 constitute guide means for guiding the first band 23 and the second band 24. This guiding means approaches the first band 23 and the second band 24 as it is separated at the engagement position of the power transmission tooth 181 and the power receiving holes 231 and 241. The guiding means then accesses the first band. The first and second bands 23 and 24 are guided so that a part of the band 23 and a part of the second band 24 are adjacent and parallel.

In the first embodiment, the following effects are obtained.

(1-1) When the wheel 18 is reciprocally rotated, the first band 23 and the second band 24 are reciprocated in the opposite directions in a state where the warpage is deformed, and the first dietary warp heald is 11 ) And the second dietary warp heald (12) reciprocate in opposite directions. The maximum amount of opening for warp-producing warp yarns can be appropriately increased by increasing the amount of one-way rotation of the wheel 18 to be reciprocated. The one-way rotational amount of the wheel 18 refers to the rotational amount of the wheel 18 for moving the hemming healds 11 and 12 for the Western-style warp yarn by only one stroke of reciprocating or double-acting. The torque required to rotate the wheel 18 can be made smaller by reducing the radius of the wheel 18, and the warp-deformable bands 23 and 24 engaged with the wheel 18 can be made lighter by making the thickness smaller. can do. Employment of the light weight bands 23 and 24 is effective for reducing the torque required to rotate the wheel 18.

(1-2) In the state where the power transmission tooth 181 of the wheel 18 enters the escape grooves 192 and 202, the power transmission tooth 181 is the power receiving hole 231 and 241 of the bands 23 and 24. ), The power transmission tooth 181 does not fall out of the power receiving holes 231 and 241 in this state. The first position regulator 19 with the escape groove 192 ensures engagement of the first band 23 with the wheel 18, and the second position regulator 20 with the escape groove 202. ) Ensures engagement of the second band 24 with the wheel 18.

(1-3) The first band 23 and the second band 24 are approached as they fall from the engaged position with the wheel 18 toward the dietary warp healds 11 and 12, and then adjacent to each other. To be parallel. The first and second bands (sliding contact portions of the first and second bands 23 and 24 in sliding contact with the guide curved surfaces 193 and 203 and in sliding contact with the guide planes 194 and 204 forming an angle α) 23, 24) portion is a straight state. That is, the first and second bands 23 and 24 are deflected in a path from the engagement position of the wheels 18 with the first and second bands 23 and 24 to the guide grooves 221 and 222.

The warp-deformed shape of the first and second bands 23 and 24 from the engaged position of the first and second bands 23 and 24 to the wheels 18 to the guide grooves 221 and 222 is appropriate for the angle α. It can adjust to a suitable shape by selecting so that it may be selected. The proper shape here is a bending deformation shape for reducing the sliding resistance between the position regulators 19 and 20 and the bands 23 and 24 and the sliding resistance between the guide rails 22 and the bands 23 and 24. Say

(1-4) Flexurally deformed shape of the first and second bands 23, 24 from the engaging position of the first and second bands 23, 24 to the wheels 18 to the guide grooves 221, 222. Can be considerably changed to some extent by changing the curvature of the guide curved surfaces 193 and 203 which are circular arc curved surfaces. Guide curved surfaces 193 and 203 are deflections of the first and second bands 23 and 24 from the engagement positions of the first and second bands 23 and 24 to the wheels 18 to the guide grooves 221 and 222. It contributes to adjusting the shape to an appropriate shape. Further, circular arc curved surfaces which are easily formed may be preferable as the guide curved surfaces 193 and 203.

(1-5) The shape of the band 23, 24 part extended upward from the engagement position of the 1st and 2nd band 23 and 24 and the wheel 18 is linear shape. Such a straight line shape is effective for reducing the sliding resistance between the position regulators 19 and 20 and the bands 23 and 24 and the sliding resistance between the guide rails 22 and the bands 23 and 24.

(1-6) In general, the hemp seedlings 11 and 12 for planting warp are arranged in the empty space after removing the seedling frame in front of the loom among the seedling frames for forming the woven fabric forming inclined opening. Is placed at the rearmost of the. When arranging the warp-healing healds 11 and 12 in front of the heald frame, the distance between the arrangement positions of the latch arms 25 and 26 and the arrangement positions of the latch arms 27 and 28 in the front-rear direction of the loom. The larger the position becomes, the farther the position of the rear end of the end-of-day cooking warp frame is moved toward the rear side of the loom. For this reason, the stroke amount of the upper and lower ends of the rear end seedling frame for a dietary preparation warp becomes large, and it is disadvantageous for driving a seedling frame. In addition, in the case of arranging the planting warp healds 11 and 12 at the rear of the seedling frame, the opening amount of the planting warp healds 11 and 12 needs to be increased, so that a large torque motor is required. It is disadvantageous.

Bands 23 and 24 made of fiber-reinforced plastic reinforced with carbon fibers are flexibly deformed so that the bands 23 and 24 are parallel to each other (parts in the guide grooves 221 and 222 of the guide rail 22). The spacing of can be made small. Therefore, the distance between the arrangement positions of the latch arms 25 and 26 and the arrangement positions of the latch arms 27 and 28 in the front and rear directions of the loom can be reduced. This contributes to reducing the stroke amount of the rear end seedling frame for food preparation warp.

(1-7) The first band 23 is in sliding contact with the metal first position regulator 19 and the metal guide rail 22, and the second band 24 is the metal second position regulator ( 20) and the metallic guide rail 22 in sliding contact. The sliding contact resistance of the fiber-reinforced plastic and metal reinforced with carbon fiber is small. Fiber-reinforced plastics reinforced with carbon fibers are preferred as the material of the bands 23 and 24 capable of bending deformation.

(1-8) The electric motor 17 which is independent from the linearly driven motor (not shown) and can cope with the formation of various dietary structures is preferable as a driving source for reciprocating the wheel 18.

Next, 2nd Embodiment of FIG. 5 is described. The same code | symbol is used for the same structural part as 1st Embodiment.

In the reciprocating drive mechanism 13A of the second embodiment, the electric motor 17 is attached to the box 16 via the auxiliary plate 32. The drive gear 29 is fixed to the output shaft 171 of the electric motor 17. The support shaft 30 is rotatably supported on the inner wall 161 and the outer wall 162 of the box 16, and the wheel 18 and the driven gear 31 are fixedly mounted on the support shaft 30. The drive gear 29 is engaged with the driven gear 31, and the reciprocating rotation of the output shaft 171 is transmitted to the support shaft 30 through the engagement of the drive gear 29 with the driven gear 31. As a result, the support shaft 30 and the wheel 18 reciprocate integrally. The other structure is the same as that of 1st Embodiment.

If the ratio of the number of teeth of the drive gear 29 and the driven gear 31 is selected suitably, a speed increase mechanism or a deceleration mechanism can be comprised. Such a configuration brings about the advantage that the speed increase ratio or the reduction ratio can be selected according to the torque characteristics of the electric motor 17.

Next, 3rd Embodiment of FIGS. 6-10 is demonstrated. The same code | symbol is used for the same component part as 1st and 2nd embodiment.

As shown in Fig. 6, the first dietary warp heald heald 11 and the second dietary warp heald heald 12 are driven up and down in opposite directions by the reciprocating drive mechanism 33. As shown in FIG. 7, in the box 34 constituting the reciprocating drive mechanism 33, the base frame 35 is rotatably supported through the support shafts 36 and 37. The axial direction of the support shafts 36 and 37 is the indentation direction of the weft thread.

As shown in FIGS. 8A and 8B, the connecting shaft 38 is rotatably supported in the base frame 35. The axis of the connecting shaft 38 is orthogonal to the axis of the support shafts 36, 37. A coupling shaft 39 of a T-shape is coupled and fixed to the coupling shaft 38, and another coupling shaft 40 is coupled and fixed to the coupling shaft 39. The axis of the connecting shaft 38 and the axis of the connecting shaft 40 are orthogonal to each other.

The electric motor 41 is attached to the upper surface of the upper side wall 341 of the box 34. The output shaft 411 of the electric motor 41 penetrates through the upper side wall 341 and protrudes into the box 34, and an angle member 42 is fixedly attached to the distal end of the output shaft 411. The connecting shaft 40 is rotatably connected to the angle member 42. When the output shaft 411 rotates, the connecting shaft 40 revolves around the axis of the output shaft 411. When the connecting shaft 40 revolves around the axis of the output shaft 411, the connecting shaft 38 is oscillated about the axes of the support shafts 36 and 37. The swing of the connecting shaft 38 is transmitted to the support shafts 36 and 37 via the base frame 35 so that the support shafts 36 and 37 reciprocate. The angle member 42, the connecting shaft 40, the connecting tool 39, the connecting shaft 38, the base frame 35, and the support shafts 36 and 37 constitute a three-dimensional crank mechanism 43. The support shaft 37 becomes a reciprocating output shaft of the three-dimensional crank mechanism 43.

As shown in FIG. 7, the support shaft 37 protrudes from the front side wall 342 of the box 34 to the outside of the box 34, and the drive gear 44 is fixed to the protruding end of the support shaft 37. It is installed. The cover 45 is fixedly mounted on the front wall 342 of the box 34, and the support shaft 46 is rotated on the front wall 451 of the cover 45 and the front wall 342 of the box 34. Possibly supported. A driven gear 31 and a wheel 18 are fixedly mounted to the support shaft 46, and a drive gear 44 is engaged with the driven gear 31. The number of teeth of the drive gear 44 is larger than the number of teeth of the driven gear 31. The other structure is the same as that of 1st and 2nd embodiment.

Next, the operation of the third embodiment will be described.

The output shaft 411 of the electric motor 41 rotates in one direction, and the rotation of one direction of the output shaft 411 is converted into reciprocating rotational motion by the three-dimensional crank mechanism 43. That is, the support shaft 37 constituting the three-dimensional crank mechanism 43 reciprocates. When the support shaft 37 reciprocates, the drive gear 44 reciprocates integrally, and the rotation of the drive gear 44 is transmitted to the driven gear 31. Thereby, the support shaft 46 rotates reciprocally in the direction opposite to the rotation direction of the drive gear 44 at a rotation speed larger than the rotation speed of the support shaft 37. When the support shaft 46 reciprocates, the wheel 18 reciprocates integrally, and the first band 23 and the second band 24 reciprocate in opposite directions.

When the three-dimensional crank mechanism 43 is in the arrangement state of Fig. 8 (a), the first band 23 is at the highest operating position indicated by the broken line and at the same time, the lowermost operation indicated by the second band 24 is indicated by the broken line. In position. When the three-dimensional crank mechanism 43 is in the arrangement shown in Fig. 8 (b), the second band 24 is at the highest operating position indicated by the broken line and the first band 23 is shown by the broken line.

In the graph of FIG. 9, the horizontal axis θ represents the loom rotation angle, and the vertical axis represents the height position. In addition, the line described as horizontal axis (theta) in FIG. 9 corresponds with the height position of the warline of the loom. The positional change of the second formulated warp heald when the three-dimensional crank mechanism 43 is used is represented by a curve E2 similar to a curve in which the curve E1 is inverted up and down on the horizontal axis θ.

Curve D1 in the graph of FIG. 9 shows the change of position of the 1st preparatory warp seedstone 11 when the conventional two-dimensional crank mechanism is used and the rotation speed of an electric motor is made constant. The positional change of the second formulated warp heald when the two-dimensional crank mechanism is used is represented by a curve D2 similar to the curve in which the curve D1 is inverted up and down on the horizontal axis θ.

The example of FIG. 9 is an example which forms the planting structure of 1/1. In other words, the first dietary warp seed heald 11 and the second dietary warp seed heald 12 are replaced up and down every turn of the loom.

Comparing curves E1 and E2 with curves D1 and D2, the range where the change in position at the dead point side of the reciprocating linear motion of the cultivation warp healds 11 and 12 when the three-dimensional crank mechanism 43 is used ( The so-called commutation range is wider than the commutation range in the case of using the two-dimensional crank mechanism. In the illustrated example, the range of the rotation angle of the loom corresponding to the height position range between the highest position H1 of the planting warp healds 11 and 12 and the height position H2 close to the highest position H1 is determined. Shall be. In addition, the range of the loom rotation angle corresponding to the height position range between the lowest position L1 of the planting warp healds 11 and 12 and the height position L2 close to the lowest position L1 is taken as the rectification range. That is, in the illustrated example, the commutation range of the seedling warp healds 11 and 12 when the three-dimensional crank mechanism 43 is used is represented by (Te1 + Te2) or (Te3 + Te4), and the two-dimensional crank mechanism The commutation range of the seedling warp healds 11 and 12 in the case of using is represented by (Td1 + Td2) or (Td3 + Td4).

That is, the opening state of the Western-induced warp warp (inclined) of the opening amount close to the maximum opening amount in the case of using the three-dimensional crank mechanism 43 can be kept longer than in the case of using the two-dimensional crank mechanism.

(3-2) In the apparatus disclosed in Patent Literature 1, the two-dimensional crank mechanism is driven by reciprocating the electric motor. However, it is difficult to increase the rotational speed of the electric motor when the electric motor is to be reciprocated in a short cycle. This difficulty hinders the speed of the loom. In this embodiment in which the three-dimensional crank mechanism 43 is driven by the electric motor 41, the electric motor 41 only needs to rotate continuously in one direction, so that the rotational speed of the electric motor 41 can be increased. . The adoption of the three-dimensional crank mechanism 43 which can increase the rotational speed of the electric motor 41 is advantageous for speeding up the loom.

(3-3) In the present invention using the three-dimensional crank mechanism 43, in the case of the formation of the 1/1 planting structure, the rectification range of the planting warp healds 11 and 12 without accelerating and decelerating the electric motor 41. Since it is possible to widen, the electric motor 41 having a small torque can be adopted. This results in a reduction in the cost of the electric motor 41.

Curve E3 in the graph of FIG. 10 shows the positional change of the first formulated warp seedling 11 when the three-dimensional crank mechanism 43 is used. In the graph of FIG. 10, the horizontal axis θ represents the loom rotation angle, and the vertical axis represents the height position. In addition, the line described as horizontal axis (theta) in FIG. 10 corresponds with the height position of the warline of the loom. The positional change of the second formulated warp heald when the three-dimensional crank mechanism 43 is used is represented by a curve E4 similar to a curve in which the curve E3 is inverted up and down with the horizontal axis θ as a boundary.

Curve D3 in the graph of FIG. 10 shows the positional change of the first formulated warp seedling 11 when the conventional two-dimensional crank mechanism is used. The positional change of the 2nd ceremonial warp heald when the two-dimensional crank mechanism is used is represented by a curve D4 similar to a curve in which the curve D3 is inverted up and down with the horizontal axis θ as a boundary.

The example of FIG. 10 is an example of forming a 2/2 dietary tissue. In other words, the first dietary warp seed heald 11 and the second dietary warp seed heald 12 are replaced up and down every two revolutions of the loom.

In the formation of a 2/2 patterned structure in the case of using the two-dimensional crank mechanism, when the electric motor is to be reciprocally rotated as shown by curves D3 and D4, the electric motor is stopped and the rapid acceleration and deceleration are required. In the formation of a 2 / 2-row structure in the case of using the three-dimensional crank mechanism 43, the acceleration and deceleration of the electric motor 41 is necessary because the electric motor 41 does not need to be reciprocally rotated as shown by curves E3 and E4. none. In addition, a small torque is sufficient even when the electric motor 41 is stopped and started.

In addition, when the electric motor 41 is used as the driving source of the three-dimensional crank mechanism 43, the formation of a complex structure such as the formation of a 1/3 phylogenous structure can also be performed without rapidly accelerating and decelerating the electric motor 41. In the formation of the 1/3 dietary tissue, the first dietary warp heald heald 11 and the second dietary warp heald heald 12 are replaced up and down after three turns of the loom after being replaced up and down, or after one turn of the loom thereafter. It is replaced up and down.

That is, the electric motor 41 which can respond to formation of various eating patterns independently of the loom driving motor (not shown) is preferable as the driving source of the three-dimensional crank mechanism 43.

(3-4) The larger the reciprocating angle beta (shown in Fig. 8 (a)) of the support shaft 46 is, the larger the maximum opening amount of the opening formed by the ordinal warps 14 and 15 is. This is advantageous for weaving the weft. In the three-dimensional crank mechanism 43, it is difficult to enlarge the reciprocation angle (gamma) (shown in FIG. 8 (a)) of the support shafts 36 and 37 which reciprocally rotate. The speed increase mechanism composed of the drive gear 44 and the driven gear 31 speeds up the output from the three-dimensional crank mechanism 43 and transmits it to the wheel 18. In other words, the speed increasing mechanism composed of the drive gear 44 and the driven gear 31 makes the reciprocating angle β of the support shaft 46 larger than the reciprocating angle γ. Such a speed increasing mechanism is effective for increasing the maximum opening amount in the adoption of the three-dimensional crank mechanism 43.

However, the roller may be brought into contact with the bands 23 and 24 in the range between this engagement position and the guide rail 22.

(7) In the third embodiment, the box 34 may be an oil tank, and lubricant may be put into the box 34 to lubricate the three-dimensional crank mechanism 43. In this case, since the electric motor 41 is located above the box 34, the box 34 can be easily configured so that lubricating oil does not enter the inside of the electric motor 41.
