The action member includes a disk member for untwisting and twisting a yarn as a yarn joining target. A gas flow is configured to flow from the inside of the housing to the outside while passing in the vicinity of the disk member.

  As a result, since the fluff generated in the housing during untwisting or twisting and adhering to the disk member can be discharged and removed to the outside by an air flow, a stable yarn splicing operation over a long period of time can be realized. Can do. Further, the maintenance frequency for removing the fluff can be reduced.

  ◆ According to the second aspect of the present invention, a mechanical splicer device configured as follows is provided. A yarn joining operation including an untwisting step of untwisting the yarn as the yarn joining target, a removing step of removing the excess end yarn, and a twisting step of twisting the yarn is performed. In order to perform at least one of the yarn untwisting step, the removing step, and the twisting step, an action member that contacts the yarn and a housing that covers the action member are provided. The action member includes a clamp member for removing a yarn as a yarn joining target. The gas flow is configured to flow from the inside of the housing to the outside while passing in the vicinity of the clamp member.

  Thereby, since the fluff generated in the housing at the time of removing the yarn and adhering to the clamp member can be discharged and removed to the outside by an air flow, a stable yarn joining operation over a long period of time can be realized. Further, the maintenance frequency for removing the fluff can be reduced.

  In the mechanical splicer device, it is preferable that a portion of the housing corresponding to the clamp member is opened.

The upper thread Y2 is guided to the splicer device 7 by turning from top to bottom.

  1 and 2 are perspective views of the appearance of the splicer device 7. The splicer device 7 includes upper and lower surface covers 21 and 21 that cover the upper and lower sides of the internal mechanism and left and right surface covers 22 and 22 that cover the left and right sides. Furthermore, the back side of the splicer device 7 is covered with a back cover 25. Further, thread guide members 23 and 24 that also serve as a front cover are attached side by side so as to cover the front side of the splicer device 7. The housing 32 of the splicer device 7 of the present embodiment is constituted by the upper and lower surface covers 21, the left and right surface covers 22, the back surface cover 25, and the thread guide members 23 and 24.

  The two thread guide members 23 and 24 constituting the front side of the housing 32 are arranged while forming a gap having a predetermined width, and thereby, the two thread guide members 23 and 24 are elongated in the vertical direction. A thread introduction groove 26 is formed. Thus, the upper thread Y2 and the lower thread Y1 can be guided into the thread introduction groove 26 formed on the front side of the housing 32. In other words, in the splicer device 7 of the present embodiment, the set surface on which the yarns Y <b> 2 and Y <b> 1 are set is configured on the front side of the housing 32.

  In addition, thread shifting levers 27 and 27 are rotatably disposed at positions of front side end portions of the upper and lower surface covers 21 and 21 of the housing 32, respectively. When the yarn gathering levers 27 and 27 are rotated in this configuration, the yarns Y2 and Y1 are guided by the inclined guide surfaces formed on the yarn guide members 23 and 24 at the opening end position of the yarn introduction groove 26. However, it can be introduced into the yarn introduction groove 26.

  In the housing 32, disk members (acting members) 28 and 28 are rotatably supported in a state of facing each other, with respect to the upper thread Y2 and the lower thread Y1 introduced into the thread introduction groove 26. The two disk members 28 and 28 come into contact so as to sandwich the yarn Y2 and Y1, and in this state, the disk members 28 and 28 are rotated in opposite directions to untwist the two yarns Y2 and Y1. And can be twisted. Also, clamp members (action members) 29 and 29 for clamping the yarns Y2 and Y1 and removing excess end portions are provided inside the housing 32 and above and below the disk members 28 and 28, respectively. Has been placed. However, in the drawings of the present application, only the lower clamp member 29 of the upper and lower clamp members 29, 29 is shown as a representative in FIG.

  The movable parts such as the yarn shifting levers 27 and 27, the clamp members 29 and 29, and the disk members 28 and 28 are arranged in the vicinity of the yarn introduction groove 26. Further, these movable parts are driven by a drive mechanism using a cam, an arm, a link, and a gear (not shown) disposed inside the housing 32. As this drive mechanism, for example, a known mechanism as shown in Patent Document 1 may be used.

  As shown in FIG. 2, a cylindrical compressed air plug 33 projects from the back cover 25 that forms the back side of the housing 32. A compressed air inlet (gas inlet) 34 is formed at the tip of the compressed air plug 33, and a pipe (not shown) is connected to the compressed air inlet 34 to compress the compressed air from the compressed air source with the pipe. It can be introduced into the housing 32 through the air plug 33. In addition, a valve (not shown) is installed between the compressed air source and the compressed air inlet 34, and the opening and closing of the valve is controlled by a controller (not shown) installed in the unit frame 13.

  In addition, one of the two yarn guide members 23 and 24 constituting the front side of the housing 32 has two polygonal discharge windows (open portions) 30 and 30 arranged vertically in a penetrating manner. Is open. The discharge windows 30 are provided at positions on the side of the yarn introduction groove 26 (positions different from the yarn introduction groove 26).

  Furthermore, discharge openings (open portions) 31 and 31 are formed in the yarn guide member 24 at positions above and below the region where the two discharge windows 30 and 30 are provided. The discharge openings 31 and 31 are connected to the upper end portion and the lower end portion of the yarn introduction groove 26, respectively. The discharge openings 31 and 31 are formed at positions facing the upper and lower clamp members 29 and 29, respectively.

  With the above configuration, during the yarn splicing operation by the splicer device 7 (the yarn untwisting step and the twisting step by the disk members 28 and 28, and the removal of the excessive end portion of the yarn by the clamp members 29 and 29) The valve is opened. Then, the compressed air is supplied to the compressed air introduction port 34, and the compressed air is introduced into the housing 32 from the back side, whereby the pressure in the housing 32 increases. Therefore, the air in the housing 32 escapes to the front side through the yarn introduction groove 26, and the white arrows in FIGS. 1 and 2 pass through the discharge windows 30 and 30 and the discharge openings 31 and 31 formed on the front surface of the housing 32. While forming an air flow like this, it escapes diagonally above the front and below the front.

  Therefore, the fluff generated when the disk members 28 and 28 are untwisted and twisted and the yarns are removed by the clamp members 29 and 29 can be discharged from the inside of the housing 32 by the air flow. Good yarn splicing work (yarn splicing operation) can be continuously performed over a long period of time, and the frequency of maintenance can be reduced.

  As described above, the mechanical splicer device 7 of this embodiment performs untwisting and twisting by bringing the disk members 28 and 28 into contact with the upper yarn Y2 and the lower yarn Y1 as yarn joining targets, Further, in the process, the yarn joining operation is performed by removing the surplus end portions of the yarns Y2 and Y1 by the clamp member 29. The splicer device 7 includes a housing 32 that covers the clamp members 29 and 29 for removing the yarns Y2 and Y1 and the disk members 28 and 28 for untwisting and twisting, and from the inside of the housing 32 to the outside. It is configured to be able to form an air flow (the white arrow in FIGS. 1 and 2).

  Therefore, since the fluff generated during untwisting, removing and twisting of the yarns Y2 and Y1 can be discharged and removed from the inside of the housing 32 by the air flow, a stable yarn splicing operation for a long period of time can be realized. In addition, the frequency of maintenance for removing the fluff can be reduced.

  The air flow passes through the vicinity of the disk member 28 and the clamp member 29 and is discharged to the outside of the housing 32. Accordingly, the fluff adhered to the disk member 28 and the clamp member 29 can be efficiently discharged to the outside.

  The housing 32 has a discharge opening (open portion) 31 formed at a portion corresponding to the clamp member 29, and the portion is open. Accordingly, the fluff adhering to the clamp member 29 can be easily discharged to the outside of the housing 32 through the discharge opening 31, and the effect of removing the fluff can be further improved.

  In addition, the splicer device 7 of the present embodiment includes the yarn introduction groove 26 for introducing the upper yarn Y2 and the lower yarn Y1 as yarn joining targets, and the housing 32 includes the discharge window 30 and the discharge opening 31 through which an air flow passes. Are provided on the side where the yarn introduction groove 26 is provided, that is, on the front side. By providing the discharge window 30 and the discharge opening 31 on the surface on the yarn introduction groove 26 side as described above, the fluff can be easily discharged. That is, as described above, in the present embodiment, the disk member 28 and the clamp member 29 are provided in the vicinity of the yarn introduction groove 26. Therefore, by arranging the discharge window 30 and the discharge opening 31 on the surface on the yarn introduction groove 26 side. The discharge window 30 and the discharge opening 31 are located in the vicinity of the disk member 28 and the clamp member 29, which are places where the fluff is likely to occur. Therefore, a simple discharge path from the place where the fluff is generated to the outside of the housing 32 can be formed, and easy and reliable discharge of the fluff can be realized.

  In the splicer device 7, a hose as an internal pipe may be connected to the end portion of the compressed air plug 33 on the inside of the housing 32, and the hose may be routed inside the housing 32. In this case, the end (jet port) of the hose is disposed in the vicinity of the clamp members 29 and 29 and the disk members 28 and 28 inside the housing 32, and the jet port is connected to the clamp members 29 and 29 and the disk. If it is configured to be directed to the members 28 and 28, the compressed air can be sprayed more directly toward the clamp member 29 and the disk member 28, so that the fluff removal effect can be further improved. In addition, it is preferable that a nozzle having a shape that narrows the cross-sectional area of the flow path is provided at the nozzle outlet at the tip of the hose, since it can be effectively removed by blowing off the fluff with a strong air flow.

  In the present embodiment, the surface (the surface on which the yarn introduction groove 26 is provided) on which the upper yarn Y2 and the lower yarn Y1 are set in the splicer device 7 is the front side of the housing 32, while the compression used for airflow. The surface for introducing air (the surface on the side where the compressed air inlet 34 is disposed) is the back side of the housing 32. In other words, compressed air for airflow is introduced into the housing 32 from the back side, which is a surface different from the set surface of the yarns Y2 and Y1. Accordingly, since the compressed air path (specifically, the piping) connected to the compressed air introduction port 34 does not interfere with the setting / removal of the yarns Y2 and Y1 to / from the apparatus 7, smooth yarn splicing work is possible. Is realized.

  The compressed air flow is formed at least at the timing of the yarn untwisting and twisting operations by the disk member 28 and the yarn removing operation by the clamp member 29. Therefore, the fluff discharge by the air flow is effectively performed at the timing when the fluff is easily formed, and the fluff can be efficiently removed from the housing 32.

  Alternatively, the air flow may be formed from the stage before the splicing operation by the splicer device 7 is started, for example, by always opening the valve. By doing so, the fluff generated during the yarn splicing operation can be reliably blown out of the housing 32 and removed.

  The preferred embodiment and the modification of the present invention have been described above. However, for example, the following modifications can be made to the above configuration.

The shape and position of the discharge window 30 and the discharge opening 31 are not limited to those shown in FIGS. 1 and 2. For example, the discharge window 30 or the discharge opening 31 may be a circular discharge window 30 or the center of the yarn guide member 24. The shape and position of the opening that allows the airflow to pass therethrough can be arbitrarily changed, such as disposing the discharge window 30 or forming the discharge window 30 or the discharge opening 31 on the other side of the yarn guide member 23. Also, the direction of the air flow that passes from the inside of the housing 32 to the outside can be changed so as to form an air flow not in the oblique direction but, for example, straightly toward the front (in the horizontal direction). The housing 32 is also formed in a substantially rectangular parallelepiped shape in the above embodiment, but is not limited to this.

The compressed air flow may be ejected at any timing. For example, it can be ejected at all times as described above, or can be ejected only at the time of yarn joining operation. Further, for example, the compressed air flow is continuously ejected from the time before the start of the yarn joining operation (for example, when the yarn is cut by the cutter 8a of the clearer 8 or when the yarn breakage is detected) until the completion of the yarn joining operation. It can also be configured to be. Further, instead of simply switching whether or not air is ejected, for example, the air can be ejected at a low pressure during normal times, and the air can be ejected at a high pressure only during yarn joining work.

○ In addition to the time from the start to the end of the yarn splicing operation, in addition to the case where it is always ejected, it is ejected only during the yarn removal operation, or only during the untwisting operation or twisting operation. You can make it. In addition, the pressure of the ejection can be increased or decreased during the yarn joining operation.

As a gas flow for removing fluff, an air flow by compressed air is used in the above configuration, but any gas (gas) can be used without being limited thereto.

In place of, or in addition to, the configuration in which the fluff is blown off with compressed air, a configuration in which a suction connected to a negative pressure source is provided to remove the fluff can be changed. It is conceivable that the suction port for the suction is disposed in the vicinity of the discharge window 30 and the discharge opening 31, for example.

The compressed air plug 33 can be provided not only on the back cover 25 but also on, for example, the upper and lower cover 21, the left and right cover 22, and the thread guide members 23 and 24. In other words, the compressed air introduction port 34 can be arranged not only on the back side of the housing 32 but also on the top and bottom surfaces, the left and right side surfaces, or the front side. However, if the compressed air plug 33 is provided in addition to the yarn guide members 23 and 24 on the front side (other than the front side where the yarn is set), a compressed air flow can be easily formed from the housing 32 toward the front side, Further, the set yarns Y2 and Y1 are preferable in that they do not easily interfere with the piping from the compressed air source.

○ The configuration that forms the above air flow is a system in which a protective cover is provided on the front side of the housing, the protective cover is closed during normal operation, and the protective cover is opened only for yarn splicing work to set / remove the yarn. It can also be applied to other splicers. In this case, an air flow that passes through the open portion such as the discharge window is formed with the protective cover closed, or an air flow that passes through the opened portion with the protective cover opened. Can be.

The configuration for disposing the compressed air ejection port in the vicinity of the disk member 28 and the clamp member 29 is not limited to the method of drawing the hose inside the housing 32 as described above. For example, a hole is formed in a gear, a cam, a lever, or the like that forms a part of a drive mechanism such as a disk member 28 or a clamp member 29 disposed in the housing 32, and a compressed air path is formed in the hole. In addition to the configuration, it is conceivable to form a jet outlet for jetting compressed air toward the disk member 28 or the clamp member 29 at the opening end portion of the hole.

In the above embodiment, the yarn introduction groove 26 is formed on the front side of the housing 32. However, the present invention is not limited to this, and the set surface of the yarns Y2 and Y1 is, for example, the housing according to the layout of the traveling path of the yarn Y. 32 may be the upper surface side, the side surface side, or the back surface side.

The mechanical splicer device of the present invention can be applied not only to the automatic winder as described above but also to general textile machines equipped with a yarn splicing device.
