Description

  The present invention relates to a loom, and more particularly to a transmission device for a loom capable of improving the weaving function of warp and weft yarns with a hook member and extending the service life of a drive cam and the hook member.

  A loom is a machine that weaves warp and weft yarns together. For example, it is often found in looms for processing fasteners and narrow high-speed looms, and the loom is used to fabricate nylon material on both sides of the fasteners. Weaving a long and slender woven product.

Existing looms are disclosed in, for example, Taiwan Utility Model Publication No. 051775 and Taiwan Patent No. I323750. According to this, the vertical movement of the hook member mainly drives the swing arm by the rotational movement of the cam, the swing arm moves the corresponding hook member up and down, and the warp is arranged on the hook member. The warp is woven into the warp when the weft reciprocates, and the warp moves up and down in conjunction with the weft by the vertical movement of the hook member.
Moreover, in the existing loom, the shaft is connected to the camshaft through the structure of the worm and the worm wheel, and the weft is reciprocated by the rotational motion. As described above, the existing loom is for weaving the warp and weft into an elongated cloth by the vertical movement of the heel member and the weft reciprocating with respect to the warp.

Taiwan Utility Model Notification No.051775 Taiwan Patent No. I323750 Taiwan Patent Notice No. I334455 Chinese Patent Publication No. 1099438 Chinese Utility Model No. 2010201010370 Korean Patent No. 10-0495108

However, the shaft of the existing loom is composed of a combination of four worms and a worm wheel with 32 teeth, and is connected to the camshaft by a transmission structure with a ratio of 1: 8. Therefore, the shaft is rotated at 1000 rpm. The camshaft rotates at 125 rpm.
However, according to this configuration, even if the rotational speed of the shaft is adjusted to 2000 rpm in order to increase the production amount of the woven product, the rotational speed of the camshaft is only 250 rpm, so that the weft weaving operation is efficient. is not.

Moreover, since the cam curve of the cam of the existing loom has 8 phases, the cam moves up and down once every 45 degrees. That is, when the shaft rotates once, the vertical movement of the eaves member is performed eight times.

In this embodiment, ten guide holes 5000 are formed in the guide seat 500, and the pulling rods 522 of the collar plate 52 are inserted into the guide holes 5000 of the guide seat 500, respectively.

  As shown in FIGS. 5, 16, and 17, when the plurality of cams 35 rotate and come into contact with the contact bearing 422 at one end of the arm 42 by the rising cam curve portion, one end of the arm 42 is lifted, The interlocking portion 423 at the other end is lowered. At this time, since the interlocking portion 423 is fixed to the connecting block 523, the connecting block 523 pulls the saddle plate 52 downward through the pulling rod 522 so as to resist the urging force of the spring 525, and the plurality of cams 35. When the ascending cam curve part moves away from the arm 42 while continuing to rotate, the saddle plate 52 is released and is restored by the urging force of the pulling bar 522.

  Since the through-groove 511 of the mounting plate 51 and the guide groove 531 of the guide plate 53 are structured to guide the vertical movement of the eaves plate 52, the eaves plate 52 is stably moved up and down along the through-groove 511 and the guide groove 531. Can move.

As shown in FIG. 18, since the fourth cam 354 of the present invention has four phases, the second cam 352 rises or falls once every 90 degrees while the second cam 352 rotates once. On the other hand, as shown in FIG. 20, the cam of the existing loom has 8 phases (up and down movement, that is, up and down movement that repeats the operation of raising once and then descending once). The cam rises or falls every 45 degrees. As described above, since the cam is frequently raised and lowered and vibrates vigorously, the cam is subjected to considerable vibration, the cam is worn out, and the warp wound around the heel plate 52 is easily broken. .
18 is the difference between the maximum distance and the minimum distance from the center of the cam to the outer peripheral surface, that is, the distance between the lowest position and the highest position of the contact bearing 422 in the arm 42. It is.

  As shown in FIG. 19, in the rotation of the first cam 351 in the present invention, the arm 42 is held at a high position from 0 degrees to 180 degrees, and when the first cam 351 rotates to 270 degrees, the arm 42 is lowered. The position is reached, and once up or down every 90 degrees. As shown in FIG. 21, the conventional loom cam raises or lowers once every 45 degrees (performs up-and-down motion that rises three times and then lowers once). cause.

  The worm 24 in the present invention is an eight-row worm and has a ratio of 1: 4 transmission structure in which the worm wheel 33 has a worm wheel having 32 teeth. According to this configuration, when the rotational speed of the turntable 32 is increased from 1000 rpm to 2000 rpm, the rotational speed of the transmission shaft 31 is increased from 250 rpm to 500 rpm, and the cam 35 and the arm 42 each time the shaft 23 rotates once. The heel plate 52 moves up and down once and performs a single weaving operation. In other words, when the rotational speed of the transmission shaft 31 increases with the rotational speed of the shaft 23, the number of times that the reed plate 52 is raised and lowered increases, so that the operation of the reed plate 52 increases within a unit time. Ability improves.

  The existing loom is composed of a combination of four worms and thirty-two worm wheels and has a transmission structure with a ratio of 1: 8. Therefore, when the shaft rotates at 1000 rpm, the camshaft rotates at 125 rpm. The rotation speed of the present invention is considerably lower than that of the cam having 250 rpm. In this configuration, even if the rotational speed of the shaft is increased to 2000 rpm, the rotational speed of the cam increases only to 250 rpm. In addition, since the existing loom uses an 8-phase cam, when the rotational speed is increased, the cam vibrates more violently, and the cam wear loss and warp yarns are likely to break.

On the other hand, in the transmission device of the loom according to the present invention, since the cam 35 has a four-phase cam curve, each time the cam 35 makes one rotation, the eaves plate 52 performs the lifting / lowering operation four times. That is, the warp yarn and the weft yarn can perform the weaving operation four times. In addition, the operator can adjust the height position of each cam 35 according to the thickness of the woven product, and can adjust the opening degree of the eaves plate 52.
In addition, according to the loom having an existing 8-phase cam, when the shaft makes one rotation, the weaving operation can be performed 8 times. It is necessary to adjust the degree of opening of each.

In the loom transmission device according to the present invention, the eight worms 24 in the worm gear transmission member 20 mesh with the worm wheel 33 of the cam assembly 30, so that the rotation speed of the transmission shaft 31 matches the rotation speed of the shaft 23. To rise. According to this configuration, the weaving operation of the loom increases as the number of times of lifting and lowering of the arm plate 52 of the arm swinging member 40 and the arm member 50 increases, so that the production capacity of the weaving product is improved.
Further, since the cam curve of the cam 35 has four phases, vibration during rotation can be mitigated, so that the wear loss of the cam 35 can be suppressed and the service life of the warp wound around the heel plate 52 can be extended. it can.
Furthermore, since the pivot seat 41 is adjustably attached to the coupling lid 13 and the arm 42 pivots with respect to the pivot seat 41, the swing range of the arm 42 can be adjusted. In other words, by adjusting the swing range of the arm 42, the elevating position of the eaves plate 52 can be adjusted, so that the number of members can be reduced and it is not necessary to prepare an arm having a plurality of different dimensions. So convenience is improved.
