Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a high speed ribbon loom for picking up a cone shuttle by shedding enlarge,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-speed loom capable of weaving grosgrain at a high speed, and more specifically, A cone type shuttle with a large coarse weft wound by the rotation of two transfer cams installed at different angles on the auxiliary shaft is picked up by the shedding to form a loop type transformer The present invention relates to a cone-shuttle high speed narrow weaving machine for weaving a shuttle grosgrain having a selvage edge at high speed.

Narrow-width fabrics are mainly used for clothing, bedding, flower and gift wrapping, hair accessories, and ribbon decorations because they are narrow and are woven in the longitudinal direction.

Among narrow-woven fabrics, woven fabrics are densely arranged in warp yarns and woven with plain woven fabrics with slightly thick woven fabrics. These woven fabrics have a calm and drab taste and are widely used as auxiliary materials that can give a luxurious accent to clothes , It is common to weave by a needle grosgrain weaving loom because of its narrow width.

North-back tack is a tape fabric that forms a loop on the servage edge to give a more luxurious appearance. Such drumsticking has been used particularly in decorative accessories of clothing, a high-grade wrapping ribbon and a hair ribbon in which aesthetic sense is important, and since such drumstick can not be woven as a needle loom, a weaving loom using a shuttle grosgrain weaving loom It is common.

As described above, the weft yarn in which the warp knitting yarn is formed in a straight shape is weaved at a high speed as a needle weaving machine, and the weft yarn is knitted in a weaving machine in the case of a shuttle grosgrain having a loop-shaped bone yarn.

Needle loom, which is a high-speed narrow loom, is a technique disclosed in the Utility Model No. 1984-0002739 and Practical New Design Office 1992-0007637 registered as utility models. However, in the conventional needle looms disclosed in the above patent documents, all of the weft yarns are inclined through the needle eye by the insertion method of a round needle, do.

The conventional needle looms shown in the above patent documents can easily control the warp tension by using a sectional warper beam. Therefore, it is possible to easily adjust the tension of the warp yarns and to weave the weft yarns at a high speed by using the elastic yarns excellent in the stretchability. However, since other applications have been extensively proposed, weft yarn weaving with a round- There was no problem.

Since the weft loom weaves the weft by widening the weft with an oblique opening, it is advantageous to easily weave the weft loom having a round-shaped weft, but it is possible to weave a single warp beam at one warp beam, There has been a problem in that it is very difficult to adjust the tension of the warp yarn when weaving the weft yarn weaving with several tens of strands, so that the elastic yarn can not be used as a warp yarn.

In addition, since the weft loom can not be wrapped around the pirn inserted in the drum, it is inconvenient to replace (or replace) the drum or bowel when the weft is woven frequently, The knot after weft has inevitably occurred in the tape fabric, which has been a cause of quality deterioration and the productivity is not good due to frequent replacement of the drum or the gut and frequent cutting of the knot after cutting the weft .

Since the weaving machine has a structure in which a drum having a relatively small size is guided by an oblique opening, the drum up driving and the opening operation of the heald are separately performed by rotation of different rotating shafts, There was a problem.

It should be understood, however, that the invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. It should be noted that the embodiments of the present invention described below are intended to sufficiently convey the spirit of the present invention to those skilled in the art.

1 to 8, a cone-shuttle high-speed width woven machine 1 according to a preferred embodiment of the present invention includes a main frame 10, a tilted beveled beam 18 being stood on the main frame 10, Winding rollers (14, 16) for winding up a fabric woven by a body needle by putting a weft in the opening and a pair of shearing frames (21, 22) for forming an opening by opening a warp, A prime mover 11 for generating rotational power for secondary motions and a power transmission portion for performing main motions and negative motions of the looms by the power of the prime mover 11 are provided.

The power front end includes a drive pulley 13 installed on the main frame 11 to transmit the power of the prime mover 11 to a lower shaft 15b and a lower pulley 13b that decelerates the rotation of the lower shaft 15b, Up roller 14 and a reduction gear (winding roller) 16 for winding the fabric. At this time, the drive pulley 13 and the lower side 15b are connected by a drive belt pulley and a follower belt pulley (not shown) installed on the rear surface of FIG. 1, and the reduction gear Decelerates the rotation of the winding roller 14 and transfers it to the nip roller 17 side. The timing of the main movement, the sub-movement and the sub-movement of the loom according to the rotation drive of the prime mover 11 should be set as the normal loom timing, and such a movement timing can be easily set by a person skilled in the art .

The opening disk 15 is provided on the side of the lower shaft 15b of the main frame 10 in which the conveying cam for conveying the cone shuttle to the left and right is provided in order to enlarge the inclined opening and the shading disk 15 One end of a shedding sword 30 is eccentrically connected. The other end of the shading sword 30 is coupled to a central portion of a shading bar 32 which is pivotally coupled to the main frame 10 at one end thereof and the other end of the shedding bar 32 is connected to a sled frame 21 To the chains 24, 25 so as to open.

When the drive pulley 13 is rotated, the lower shaft 15b provided on the lower side of the main frame 10 of the cone-shuttle high speed narrowing machine 1 is rotated. Two symmetrical conveying cams 73a and 73b are coupled to the lower side 15b as shown in FIG. 2. One of the two conveying cams 73a and 73b is rotated by a fixed shaft 71 75, which are coupled to the two seals 72a, 72b, which are coupled to the two seats 72a, 72b.

When the two legs 72a and 72b are moved up and down, two transfer rods 76 and 77 connected to the legs 72a and 72b are alternately raised and lowered. At this time, the other side of the two conveying rods 76 and 77 is formed into a disk shape as shown in FIG. 2 and FIG. 3, so that the rotational center axis is parallel to both sides of the motion converting disk 78 coupled to the main frame 10 As shown in FIG. Therefore, when the drive pulley 13 and the lower shaft 15b connected to the drive pulley 13 are rotated by the driving of the prime mover 11, the cam of the transfer cams 73a and 73b drives the motion converting disc 78 From left to right, from right to left. That is, the linear motion is converted into the rotational motion.

At this time, the driving motion converting disc 78 and the driving gear shaft 56 provided at regular intervals to the main frame 10 are connected to each other by an annular conveying belt 59 via a belt pulley 58. The driving gear shaft 56 is installed on a bracket 10a provided at a predetermined interval and is used as a passage through which a warp thread is passed between the brackets 10a. Therefore, when the lower shaft 15b is rotated, the motion converting disc 78 is rotated to the left and right by the driving of the conveying cams 73a and 73b so that the driving gear shaft 56 provided in the bracket 10a is also rotated to the left and right .

5, a driving gear 56a is coupled to the driving gear shaft 56 on the front face of the bracket 10a, and two driven gears 56b engaged with the upper portion of the driving gear 56a are installed And a cradle feeder 51 are respectively installed. 5, a cone shuttle cradle 52 having a linear gear 52c engaged with the two driven gears 56b is coupled to the cradle feeder 51. As shown in FIG. A cone fixing rod 52d is coupled to the front surface of the cone cradle 52 as shown in FIG.

As shown in FIGS. 5 and 7, the cone cradle 54 to which the cone 53 wound with the thick weft yarn Wf is inserted is inserted into the cone fixing rod 52d, and then the nut is coupled to the cone cradle 54d. The cone cradle 54 is formed in a loose shape so that the cone 53 can be inserted into the inside of the cone cradle 54. The upper crown wound around the cone 53 is inserted into a compression coil spring Spring) 54 to the weft delivery opening. At this time, the reason why the weft yarn is fed across the compression coil spring 54 is to prevent unnecessary unwinding of the weft from the cone when the cone shuttle is moved after the body is struck.

As shown in FIG. 2, the shedding sword for forming an inclined opening by vertically crossing up and down the sash plates 21 and 22 is provided on the opening disk 15 coupled to the lower shaft 15b. (Not shown). The other side of the shedding sidewall 30 is connected to the center of an shedding bar 33 having one end thereof axially coupled to the fixed shaft of the main frame 10, Is connected to lifting chains 24 and 25 connected to the beam frames 21 and 22 via roller bearings 23 provided at the upper end of the main frame 10. [

Although not shown in detail in the drawings, another opening disc is connected to the other side of the lower shaft 15b, and another opening disc is connected to another opening disc through another shading sword eccentric to the upper opening disc 15 It will be appreciated by one of ordinary skill that the frame is lifted.

The opening disc 15 shown in Figs. 1 to 3 and the shedding sword 30 eccentric to the disc 15 are alternately lifted and lowered from the sill plates 21 and 22, 21 and 22 is determined according to the diameter of the opening disk 15 and the state of eccentric engagement on the disk surface of the opening disk 15. [ That is, as the diameter of the opening disk 15 is large and the eccentrically coupled shedding sword 30 is closer to the outer peripheral surface from the central axis of the opening disk 15, the size of the opening is further increased.

Therefore, when the rotational force of the prime mover 11 shown in FIG. 1 is transmitted to the lower shaft 15b through the main drive pulley 12 and the drive pulley 13, the rotational force of the prime mover 11 is transmitted to the opening disk 15 coupled to the lower shaft 15b It can be seen that the end frames 21 and 22 are elevated by the operation of the eccentrically joined shedding sword 30 to enlarge the opening of the warp WP connected from the oblique beam 18 to the front rest 19. By operating the conveying cams 73a and 73b coupled to the lower shaft 15b as shown in Figs. 2 and 3, the cone-shuttle moving device 50 constructed as shown in Fig. 4 is driven, The conical cradle 52 engaged with the driven gear 52b of the cradle 52a moves left and right to guide the weft wound around the cone 53 into the inclined opening.

After the warp opening and weft insertion are performed by the above operation, the body sinking operation is performed, as follows. The body sink part for sinking the weft is composed of a slay sword 41 eccentrically coupled to the disc of the driving pulley 13 coupled to the main frame 10 and a sled sword 41 A sled coupler 42 coupled to an end of the sled 40 and a rail guide 45 coupled to a side surface of the main frame 10, A rear board 43 coupled to the rear of the body rail 43 and a body 46 coupled to an upper portion of the board 44. The rear board 43 is connected to the rear board 43, . As is well known in the art, the body 46 should be inclined in the gap when the inclination is maintained.

When the driving pulley 13 is rotated, the sled sword 41 eccentrically coupled to the disk of the driving pulley 13 is moved back and forth along the rotating disk and is connected to the fixed shaft at one side And the sley 40 in which the slave word 41 is coupled to the intermediate portion is moved back and forth in synchronism with this. When the sled 40 is moved back and forth, the body rail 43 is moved back and forth along the rail guide 45 coupled to the side of the main frame 10. Therefore, the body 46 installed on the race board 44 coupled to the end of the body rail 43 causes body weigth.

When the main action of the inclined opening, the weft overrun, the inclined closing action, and the fabric body needle are successively performed, the tension of the tilt fixed on the lease rod 68 of Fig. 7, the rotation shaft 13A of the drive pulley 13 is provided with a projection 63 for raising and lowering the tension adjusting rod 60 up to immediately before closing of the slope and opening of the slope And the fixed disk 62 formed on the outer periphery is coupled. A tension adjusting disc 60 having a tension control rod 60 having one side and a latch protrusion 67 being resiliently urged by a spring 67 inserted in a hole 65 formed in one side of the fixed disc 62 ).

Since the drive pulley 13 constructed as described above is rotated and the protrusion 63 of the fixed disk 62 is inserted into the outer periphery of the tension adjusting disk 64 immediately before the oblique opening is closed, When the tilt is opened, the tension adjusting rod 60 is not rotated any more, so that the projection 63 of the fixed disk 62 pushes the latch projection 63 toward the spring 66 side. Therefore, the tension adjusting rod 60 is lifted up in the closing cycle of the inclination. In the opening cycle, the tension adjusting rod 60 is lowered to adjust the tension of the inclination.
