Description

Tilt opening device {SHEDING DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for freely connecting a heald frame and a reciprocating drive member which are provided in parallel with a plurality of inclined opening devices of a loom.

Japanese Patent Application Laid-Open No. 57-138986 discloses an opening device for a loom. The opening device of the loom of the publication has a plurality of heald frames provided in a direction of inclination, each hex frame is connected to a rod to be reciprocated through a connecting port, and reciprocally driven in an inclination opening direction to open a movement in inclination. To give. In addition, reciprocating driving members such as rods, couplings, and the like are alternately arranged at positions not overlapped in the direction of the textile width between adjacent healds.

In general, in order to minimize the damage of the inclination due to the inclined opening movement, the opening amount of the inclination must be made small. When the arrangement pitch (thickness in the inclination direction) of a plurality of heald frames formed side by side in the direction of the inclination is large, that is, when the distance between the running position of the weft yarn and the heald's heald is large, In order to obtain an inclined opening suitable for entering, a larger reciprocating motion is required in each heald as it moves away from the position before weaving. For this reason, it is considered that the thickness of the seedling frame is made thin and the arrangement pitch of the plurality of seedling frames is shortened in the inclined direction. However, the thickness of a connector tends to become thicker than a seed frame because of the problem of the strength of the connector. On the other hand, the connector is mounted directly to the heald frame. For this reason, it is necessary to avoid interference between adjacent heald frames and the connector, and the arrangement pitch of the heald frames must be widened. In short, according to the prior art, the thickness of the connector is a problem, and in order to shorten the arrangement pitch of the heald frame, there is a limit.

Accordingly, it is an object of the present invention to reduce the reciprocating amount of the seedling frame when giving a predetermined opening amount to the inclination by shortening the arrangement pitch of the seedling frame in the inclined direction.

Based on the above object, the present invention provides an inclined opening apparatus in which a plurality of heald frames and a connector for freely connecting a reciprocating drive member are disposed at positions not overlapped in the direction of a textile width between adjacent heald frames. (1) separate the connector from the range of movement of the other heald to avoid interference between the connector of one heald and the other heald of the adjacent heald; or (2) The retreat part which avoids from the range of motion of a side connector is formed.

(1) The means for separating the connector from the range of motion of the other heald frame is provided by inserting a member of the spacer part between the connector and the heald frame, or the separation part is a connector (connection foundation) or the end of the heald frame. It can be specified by forming in any one of them integrally. The formation length of the separation distance is determined in consideration of the movement range of the adjacent member.

(2) The means for forming the receding portion away from the range of motion of the other connector in the heald can be embodied by forming the receding portion avoiding the range of motion of the other connector in the heald. It is formed by making the thickness of the heald frame thin or forming a cutout in the heald frame. The formation length of the said retreat part is decided in consideration of the movement range of an adjacent member.

1 and 2 show an inclined opening device 1 of the positive drive type according to the first embodiment of the present invention. 1 and 2, the inclined opening device 1 has a connector 4 for reciprocatingly connecting the plurality of heald frames 2 and the pushing rod 31 as the reciprocating drive member 3 freely. . The plurality of healds 2 are arranged side by side in a state overlapping in the direction of inclination, and the connector 4 is inclined with respect to the direction of inclination for each healds 2 between adjacent healds 2. It is arrange | positioned in the position which does not overlap in the orthogonal weave width direction.

In the present invention, the inclined opening device 1 is characterized by providing a spaced portion 5 between the end portion of each heald frame 2 and the connector 4 as a characteristic portion. ) Is formed as a length L longer than the maximum relative distance L1 between the end of the heald frame 2 and the end of the heald frame 2 adjacent to each other in the reciprocating motion, and the connector 4 is spaced apart. In (5), it is connected to the end of the seed frame 2.

In addition, in this example, the end of the heald frame 2 is a lower portion which is connected along the textile width direction of the heald frame 2. In addition, the separation part 5 is attached to the lower end surface of the heald frame 2 by the mounting bolt 6, and the length L and the maximum relative distance L1 of the separation part 5 are heald frames. It is the length (distance) of the height direction of (2).

In this example, the separation part 5 is formed separately from the connector 4. In more detail, the space | interval part 5 has the upper end part 51, the lower end part 52, and the connection part 53. As shown in FIG. The upper end 51 and the lower end 52 constitute a corresponding mounting end of the lower end of the heald frame 2 and the connection base 41, respectively, and each mounting end should be spaced apart by a length L. , The connecting portion 53 is provided so as to be continuous to the upper end 51 and the lower end 52. In addition, a space 54 is provided in the connecting portion 53, and a mounting bolt 6 for fixing to the lower end of the heald frame 2 can be inserted therein. In addition, although each part which forms the space | interval part 5 is preferably formed integrally, it is also possible to comprise separately and to assemble. On the other hand, the connector 4 is comprised by the connection base part 41, the coupling body 42, and the rod pin 43. As shown in FIG. The connecting base portion 41 is formed in a U-shape, is mounted with a mounting bolt 44 with respect to the end surface of the separation portion 5 at one end, and the rod pin 43 is inserted at a portion where the other end is opposite. It has a dragon hole 45 and is connected to the coupler 42 by the rod pin 43 inserted in the hole 45 and the engagement hole 46 of the coupler 42. In addition, a grease nipple 47 is attached to the coupling hole 46 of the coupling body 42. By such a configuration, the connector 4 has a thickness that ensures necessary strength and durability.

In this way, the coupling body 42 is freely rotatably connected with respect to the connection base part 41, and is connected to the turnbuckle type pushing rod 31 by the screw part 48. As shown in FIG. The pushing rod 31 actively reciprocates the heald frame 2 and the heald 21 accompanying the main shaft rotation of a weaving machine (not shown) to impart an opening movement to the inclination 7.

A spacing part 5 is fitted between the heald frame 2 and the connector 4 (connector base part 41), and each spacing part 5 is a spacing part of the adjacent heald frame 2 ( It is fixed at the position shifted in the direction of the textile width so as not to interfere with 5). Furthermore, focusing on the maximum relative distance L1 with respect to the heald frame 2 of the two adjacent heald frames 2 large, the length L of the separation part 5 is heald in a reciprocating motion. Since it is longer than the maximum relative distance L1 between the lower end of the frame 2 and the lower end of the heald frame 2 adjacent to each other, each connection base portion 41 is located outside the movement range of the adjacent heald frame 2. do. The length L of the separation part 5 may be an approximation of the maximum relative distance L1, and may be a value determined in consideration of the maximum relative distance assumed in the design to a larger value than this.

The thickness of the separation part 5 is preferably equal to or less than the thickness of the heald frame 2, or in order to save energy and power consumption for driving the heald frame 2, preferably to an appropriate strength (thickness and length). In this case, a material having a small specific gravity (light weight) is used, and a space such as the space portion 54 is formed to reduce the weight.

In addition, the specific structure of the coupling tool 4 is not limited to what was shown in figure. Instead of separately configuring the separation part 5, you may form integrally with any one of the connection base part 41 or the heald frame 2, and the like. In addition, with respect to the length of the textile width direction of the space | lattice part 5, in order to reduce weight, it is also considered to make it the minimum length, to connect from the minimum length to the width direction, or to connect over the full width, etc. do.

3 and 4 are positively driven inclined opening devices 1, and healds are attached to a member mounted on a weaving machine, that is, a longitudinal guide 8, for desorption workability of the seedling frame 2; It is an example in which the spaced part 5 is integrally formed in the connector 4 connected to the lower end of the lateral guide 8 by applying to the form which hold | maintains the frame 2. The spacing part 5 is equal to or less than the thickness of the heald frame 2 or the longitudinal guide 8, or as in the first embodiment of Figs. 1 and 2 above, the end of the adjacent heald frame 2 More specifically, the lower end of the adjacent linear guide 8 is formed by connecting the length L or more than the maximum relative distance L1. In addition, the longitudinal guide 8 is attached to the side end portion of the heald frame 2 by the fastener 9 in the vertical position, and guided by the two upper and lower fixing guides 10.

In addition, although not shown in figure, the connector 4 and the pushing rod 31 are alternately arrange | positioned alternately to a textile width direction so that adjacent ones may not mutually interfere. And the space | interval part 5 is integrally formed with the connection base part 41 as shown, but may be formed separately from the connection base part 41 like Embodiment 1 of FIG. 1 and FIG.

5 and 6 are applied to the small opening drive inclined opening device 1, and the wire 32 as the reciprocating drive member 3 on the upper end and the lower end of the longitudinal guide 8. Is an example of freely connecting reciprocating motion. The upper and lower wires 32 are formed by a coupling frame 49 and a spacer 5 of the connector 4 integrated with the lateral guide 8 by the coupling 49 and the coupling pin 40. 2) is connected. In this way, the connector 4 (connector base portion 41) and the separation portion 5 are provided on both the upper and lower sides. The spacing part 5 should be less than or equal to the thickness of the heald frame 2 or the laterral guide 8, and as in the above example, the ends of the adjacent heald frame 2, in more detail, the adjacent lattes. The upper end or the lower end of the ralguide 8 is formed by connecting at a length L equal to or greater than the maximum relative distance L1.

Of course, one of the upper and lower wires 32 is driven in the forward movement direction of the reciprocating motion in conjunction with the rotation of the main shaft of the weaving machine by a cam mechanism or a link mechanism (not shown), and the other tension is not shown. The force is applied by the spring in the reverse direction of the reciprocating motion.

7 and 8, in the positively driven inclination opening device 1, instead of providing the spaced portion 5, the connector adjacent to the opposing portion of the adjacent heald frame 2 is provided. The retreat portion 11 is formed over the range of motion according to the reciprocating motion of (4). The retreat portion 11 has a width W longer than the width W of the connector 4 adjacent in the textile width direction and the length L2 of the movement range of the connector 4 adjacent by the reciprocating motion in the movement direction. It is formed in a thin thickness over. In addition, the retreat portion 11 may be formed to have a thin thickness over the required length, i.e., the width of the connector 4 in the textile width direction, or may form a cutout portion.

According to claim 1, in the inclined opening device, a spaced portion is provided between the end of the heald and the connector, this space is the maximum of the end of the heald close to the end of the heald in the reciprocating motion. It is formed longer than the relative distance, and the connector is connected to the end of the heald frame at the separation part. This arrangement makes it possible to shorten the pitch of the arrangement of the healds in the inclined direction, so that the healds located at a position far from the textile front position can be arranged closer to the front of the weave, and the inclination suitable for wefting The amount of momentum of the seedling frame required to obtain the opening can be made small compared with the conventional one. For this reason, it is possible to reduce the damage of the inclined path, to suppress the occurrence of lint and thread breaking of the cloth, and to save the energy consumption required for the reciprocating motion of the heald.

According to claim 2, since the separation portion is formed separately from the connector, the required size can be easily secured by setting the dimensions of the separation portion.
