In other words, one is disposed at a position above the upper groove portion 37 and the other is disposed at a position below the lower groove portion 37.

  From the upper and lower air outlets 34b and 34b, air to which water is added is jetted into the yarn joining hole 34a, as will be described later. The air outlets 34b and 34b are formed so as to cause swirling flows in opposite directions to occur inside the yarn splicing hole 34a. Further, the compressed air (at least a part thereof) ejected from the air jets 34b and 34b into the yarn joining hole 34a passes through the two groove portions 37 and 37, and the relevant air enters from the internal space of the yarn joining hole 34a. It escapes in a direction (horizontal direction) perpendicular to the longitudinal direction of the yarn splicing hole 34a. As a result, the twisting member 31 can twist the upper yarn Y2 and the lower yarn Y1 set in the yarn splicing hole 34a by being entangled with air while being moistened with water.

  As shown in FIG. 6, the twisting member 31 configured as described above is provided on the front side of the base member 24 so that the yarn joining hole 34 a coincides with the yarn path 27.

As shown in FIG. 2, each suction port 24 d communicates with a suction device 46 through a suction valve 45. When the suction valve 45 is opened with this configuration, air and water used for twisting can be sucked from the twisting chamber 23 through the suction port 24d and discharged outside the machine.

  As shown in FIGS. 1 and 4, the upper yarn Y2 and the lower yarn Y1 are placed on the yarn joining unit 22 above and below the untwisting members 53 and 53 arranged above and below the yarn joining unit 22, respectively. A pulling lever 54 for pulling, a cutter 55 for cutting the yarn guided by the cutting yarn guide 53a, and a clamp mechanism 56 for fixing the yarn guided by the fixing yarn guide 53b are provided in this order.

  As shown in FIG. 1 and the like, the above-described yarn shifting lever 54 is a bow-like member configured to be rotatable around a position disengaged to the side of the yarn splicing unit 22 as a rotation center. In this case, it is configured to rotate appropriately.

  Further, a shielding mechanism 61 is disposed on the side of the yarn joining unit 22. The shielding mechanism 61 includes a twisting shielding member 62 that prevents water from splashing to the front side during a twisting operation and the like, a base member wall shielding member 63 that supports the shielding member 62, and turning and turning the shielding members 62 and 63. And a shielding member rotating mechanism 64 to be moved. As shown in FIG. 3, the twisted shielding member 62 includes a shielding portion 65 having a flat front end surface and a shielding support member 66 that supports the rear end portion of the shielding portion 65. The shielding portion 65 is configured to completely cover the opening that opens the front side of the yarn splicing hole 34 a of the twisting member 31. Further, the shielding member rotating mechanism 64 rotates each member so that the opening on the front side of the yarn joining hole 34a is closed by the shielding portion 65 at the time of twisting, and water used for twisting is surrounded by the yarn joining hole 34a. It is configured to prevent splashing.

  Each component of the winding unit main body 14 described above is supported by a unit frame 13 shown in FIG. The unit frame 13 incorporates a unit control device (not shown), and has a storage unit rewritably storing a program assembled so as to operate each component and a calculation unit capable of executing the program. Furthermore, an input / output unit connected to the winding unit main body 14 so as to be able to input / output signals, and a communication unit connected to the machine control device so as to be able to perform data communication.

  In the above configuration, the operation of the splicer device 7 will be described. That is, when the spun yarn Y unwound from the yarn feeding bobbin B is wound around the bobbin Bf while traversing to form the package P, for example, a yarn breakage occurs or a yarn defect is detected by the clearer 8 and the spun yarn is detected. When the lower yarn Y1 on the yarn feeding bobbin B side and the upper yarn Y2 on the package P side are separated by cutting Y or the like, the splicing by the splicer device 7 is started.

  Specifically, the suction port 11a of the lower thread catching and guiding means 11 catches the lower thread Y1 at the position shown in the figure, and turns from the lower side to the upper side about the shaft 11b to move the lower thread Y1 forward of the splicer device 7. To guide you. At the same time, the suction mouth 12a of the upper thread catching and guiding means 12 turns from the position shown in the figure about the axis 12b from the bottom to the upper side, catches the upper thread Y2 from the package P side, and further rises around the axis 12b. The upper thread Y2 is guided to the front of the splicer device 7.

  Subsequently, a water supply operation and a first yarn shifting operation are performed. In the water supply operation, the water supply valve 43 is opened for a predetermined time, and a predetermined amount of water is supplied from the water supply tank 44 shown in FIG. 2 to the first air passage 36a. Further, in the first yarn gathering operation, the upper and lower yarn gathering levers 54 and 54 shown in FIG. 3 are appropriately rotated from the illustrated standby position, and the upper yarn Y2 and the lower yarn Y1 located on the front side of the splicer device 7 are moved. The yarn is pulled in the direction of the yarn joining unit 22 and is gathered on the yarn path 27. As a result, as shown in FIG. 4, the upper yarn Y2 passes through the yarn joining hole 34a aligned with the yarn path 27, and the side surface of the fixing yarn guide 53b of the untwisting member 53 disposed on the upper side, It will be in the state guided to the yarn guide 53a for cutting of the untwisting member 53 arrange | positioned at the side. Further, the lower yarn Y1 passes through the yarn joining hole 34a aligned with the yarn path 27, and the side surface of the fixing yarn guide 53b of the untwisting member 53 disposed on the lower side and the untwisting member disposed on the upper side. The state is guided by the cutting thread guide 53a.

  Thereafter, a clamping operation is performed, and the upper yarn Y2 and the lower yarn Y1 guided by the fixing yarn guide 53b are fixed by the upper and lower clamp mechanisms 56, respectively. Then, a cutting operation is performed, and the lower thread Y1 and the upper thread Y2 guided by the cutting thread guide 53a are cut by the cutter 55. When these clamping operations and cutting operations are completed, the untwisting operation is performed. That is, by opening the untwisting valve 47, the compressed air flows from the untwisting air port 53d to the untwisting chamber 53c, and the lower yarn Y1 and the upper yarn Y2 of the cutting yarn guide 53a are on the upper side and the lower side, respectively. The yarn ends are drawn into the untwisting chamber 53c of the untwisting members 53 and 53, and the yarn ends are untwisted.

  When the untwisting operation is completed, the shielding mechanism 61 is activated, and the front side of the yarn splicing hole 34a is shielded by the shielding portion 65. Thereafter, the yarn shifting lever 54 is further appropriately rotated so that the ends of the upper yarn Y2 and the lower yarn Y1 cut by the cutter 55 are positioned in the yarn joining hole 34a of the twisting member 31. At this time, the shielding portion 65 only abuts against the front surface of the twisting portion 34 of the twisting member 31, and the end portion in the longitudinal direction of the yarn joining hole 34a is maintained in an open state. Never touch. Therefore, the ends of the upper thread Y2 and the lower thread Y1 do not deviate from the normal positions.

  Thereafter, the twisting operation is performed, and the twisting valve 41 is switched to the open state. As a result, as shown in FIG. 2, the compressed air flows through the first air passage 36a, and a predetermined amount of water supplied to the first air passage 36a in the above-described water supply operation is atomized with the compressed air. It is ejected from the ejection ports 34b and 34b to the yarn joining hole 34a together with the compressed air. Then, the mist-like water wets the ends of the upper thread Y2 and the lower thread Y1, and the compressed air swirls in the yarn joining holes 34a in opposite directions, whereby the ends of the upper thread Y2 and the lower thread Y1 are Entangled and twist thoroughly. Then, the compressed air passes through the groove portions 37 and 37 and the like and escapes to the outside of the yarn joining hole 34a. Note that, during this twisting operation, the front side of the yarn joining hole 34a is shielded by the shielding portion 65, so that water does not spout from the yarn joining hole 34a to the front side.

  When the twisting operation is completed as described above, the shielding mechanism 61 is operated to return to the original standby posture with the front of the yarn path 27 opened, and the yarn shifting lever 54 rotates to return to the standby position. Is done. Then, the traverse drum 3 shown in FIG. 10 is rotated and the winding of the package P is resumed.

  FIG. 11 shows the appearance of the joint where the upper yarn Y2 and the lower yarn Y1 (both hemp yarns) are spliced as described above. As shown in FIG. 11, the splicer device 7 of the present embodiment forms the joint. The seam to be formed is arranged between the two winding portions T · T formed by the above-described swirl flow, and the two entanglements formed between the two winding portions T · T and spaced apart from each other. And parts C and C. The number (two) and formation positions of the entangled portions C and C correspond to the number (two) and positions of the groove portions 37 and 37 in the twisting portion 34.

  Thus, since the entangled portions C and C are formed at an interval, the size of each entangled portion C can be made smaller than the joint (FIG. 12) in the case of Patent Document 1. Therefore, the seam is not conspicuous, and the appearance of the yarn joint portion is avoided from being significantly different from the others. Moreover, since the two entangled portions C and C are formed, the strength of the joint portion can be ensured well. In other words, since two entangled portions C and C can be formed, the slit width of each of the groove portions 37 and 37 of the twisting member 31 is reduced to make one entangled portion C and C small. However, it is possible to sufficiently secure the necessary strength at the joint portion.

  As described above, the twisting member 31 provided in the splicer device 7 of the present embodiment includes the yarn joining hole 34a in which the upper yarn Y2 and the lower yarn Y1 to be twisted are set, and the yarn joining hole 34a. The air passages 34c and 34c provided in pairs so as to form a swirl flow in opposite directions to each other and the air passages 34c and 34c through the air passages 34c and 34c. In order to release the gas supplied to the yarn splicing hole 34a in a direction perpendicular to the longitudinal direction of the yarn splicing hole 34a, two grooves 37 and 37 provided to be connected to the yarn splicing hole 34a are provided. The plurality of groove portions 37, 37 are disposed between the air outlets 34b, 34b formed by the air passages 34c, 34c in the yarn splicing hole 34a. In other words, there are two air jets 34b and 34b formed in pairs as described above, one on the upper side of the upper groove 37 and the other on the lower side of the lower groove 37. Are located outside the groove portions 37, 37 (on the end side in the longitudinal direction of the yarn joining hole 34a).

  Further, when the above-described splicer device 7 is viewed from another viewpoint, it can be grasped as a configuration in which yarn splicing is performed by the following method. That is, the upper yarn Y2 and the lower yarn Y1 to be twisted are set in the yarn joining hole 34a formed in the twisting member 31, and in this state, the air passages 34c and 34c provided in pairs on the twisting member 31 are set. Compressed air is ejected from each of the yarns toward the yarn joining hole 34a, thereby forming swirling flows in opposite directions in the yarn joining hole 34a. A plurality of the compressed air thus ejected are provided in parallel between the ejection locations (the air ejection ports 34b and 34b) from the air passages 34c and 34c to the yarn splicing hole 34a. Passing through the groove portions 37, 37, it comes out to the outside.

  Further, the seam formed by the splicer device 7 or the yarn splicing method is arranged between the two winding portions T · T and the two winding portions T · T as shown in FIG. And two entangled portions C and C formed at an interval from each other.

  Therefore, it is possible to perform yarn splicing while forming a seam that has an inconspicuous appearance and is also excellent in strength.

  Although the preferred embodiment of the present invention has been described above, the above embodiment can be further modified as follows.

In the above embodiment, the case where hemp yarn is spliced has been described. However, the present invention is not limited to the above, and the splicer device 7 can also be used for splicing yarn other than hemp yarn. However, the splicer device of the above-described embodiment can splice difficultly twisted yarns (in other words, so-called special yarns) such as hemp yarns, core yarns, and double yarns with strong and inconspicuous seams, Particularly preferred.

The splicer device 7 is configured to perform piecing using compressed air to which water is added, but the liquid is not limited to water, and the gas to be ejected is not limited to compressed air. In addition, a splicer device configured to simply splice using compressed air without adding water may be configured to include the twisting member 31 of FIG. 9 to perform splicing.

In the above embodiment, the number of the groove portions 37 and 37 of the twisting member 31 is two, but may be three or more. For example, in the case of four, the four grooves 37 may be disposed between the pair of air jets 34b and 34b. However, the two groove portions 37 and 37 as in the above embodiment are preferable because the shape of the twisting member 31 can be simplified.

Further, the interval between the groove portions 37 and 37, the formation depth of each groove portion 37 and 37, the slit width, and the like are not limited to those shown in FIG. The air outlets 34b and 34b are not limited to a pair, and two or more pairs may be provided.
