JP 2001-199637 A

  However, in the configuration of Patent Document 1, blown-off lint is scattered around and adheres to the package, which may cause quality degradation.

  In addition, in order to prevent this scattering, the method of couple | bonding an untwisting pipe and a negative pressure source with a hose, and collect | recovering yarn waste can also be considered. However, this method sometimes lacks the capacity of the negative pressure source.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a splicer unit that collects lint and does not scatter it around.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  According to the viewpoint of this invention, the splicer unit provided with the exclusive dust collector for collect | recovering yarn waste is provided.

  As a result, lint does not scatter around and adhere to the machine base body or the package, so that the work environment and package quality can be improved. In addition, since the splicer unit is equipped with a dust collector, a complicated dust collection path is not required, the device is simplified, and there is no problem of lint clogging in the middle of the dust collection path. Can be reduced.

  In the splicer unit, the dust collector includes a dust collecting chamber configured in a substantially cylindrical shape or a substantially conical shape, and collects the lint by generating a swirl airflow in the dust collecting chamber. It is preferable. The “substantially cylindrical shape or substantially conical shape” includes a case where a cross section cut by a plane perpendicular to the axial direction has a donut shape.

  Thereby, the yarn waste can be efficiently collected in the dust collecting chamber by the swirl airflow.

  The splicer unit preferably has the following configuration. That is, the splicer unit includes an untwisting pipe that introduces a yarn end at the time of yarn joining and untwists the yarn end with compressed air. The dust collector includes a yarn waste introduction port for introducing yarn waste in a substantially tangential direction of the dust collection chamber, and an air flow from the untwisting pipe generated by the injection of the compressed air is the yarn waste introduction port. The vortex rotating airflow is generated by being sprayed on the surface.

  Thereby, since the yarn waste generated at the time of yarn untwisting is directly introduced into the dust collection chamber, dust collection becomes extremely easy. Further, since the swirl airflow is generated using the air flow from the untwisting pipe, the yarn waste can be recovered without requiring a negative pressure source or the like for recovering the yarn waste.

  In the splicer unit, it is preferable that an air bleeding filter is provided at at least one end in the axial direction of the substantially cylindrical or substantially conical dust collecting chamber.

  Thereby, scattering of the yarn waste from the dust collecting chamber can be prevented by the air vent filter, and at the same time, the vortex rotating airflow can be smoothly discharged through the air vent filter. Therefore, it is possible to prevent the air flow containing the yarn waste from flowing back to the untwisting pipe side.

  In the splicer unit, at least one end in the axial direction of the substantially cylindrical or substantially conical dust collecting chamber is provided with a lint discharge opening for discharging the collected lint to the outside. It is preferable.

  Thereby, the collected yarn waste can be easily discharged to the outside through the yarn waste discharge opening.

  In the splicer unit, it is preferable that a rod-like member having a circular cross-sectional shape is provided at the center of the dust collection chamber.

  Thereby, the yarn waste can be collected in the central portion of the dust collecting chamber while being entangled with the rod-shaped member. Therefore, it becomes easy to collect the lint from the dust collecting chamber.

  In the splicer unit, it is preferable that at least one end of the rod-shaped member is tapered.

  Thereby, the yarn waste can be easily collected by moving the yarn waste entangled around the rod-shaped member toward the tapered end and extracting it.

  In the splicer unit, it is preferable that at least one end in the axial direction of the substantially cylindrical or substantially conical dust collecting chamber can be opened.

  Thereby, maintenance work such as cleaning the inside of the dust collection chamber can be easily performed.

  The splicer unit is preferably detachable from the machine base with the dust collector attached.

  Thereby, maintenance work, change of the splicer unit, and the like can be easily performed. Further, since the splicer and the dust collector can be handled collectively, it is easy to attach to and detach from the machine base.

  According to another aspect of the present invention, a yarn winding machine including a plurality of winding units including the splicer unit is provided.

  Thereby, since lint does not scatter and does not adhere to a package, a high quality package can be manufactured.

  The yarn winder preferably further includes suction means for discharging the yarn waste collected by the dust collector to the outside of the dust collector.

  Accordingly, the yarn waste can be efficiently discharged to the outside of the dust collector, so that the maintenance work becomes easier.

A package 30 having a predetermined length can be formed by winding the take-up bobbin 22.

  Next, the splicer device 14 will be described with reference to FIG. FIG. 2 is an external perspective view of the splicer device 14 according to the present embodiment.

  The splicer device 14 is fixed to a panel 91 constituting the winding unit main body 16 with bolts 88 and is configured to be removable by removing the bolts 88. The splicer device 14 includes a yarn joining nozzle 94, a yarn shifting lever 96, a clamp portion 97, a yarn holding lever 98, cutters 92 and 93, an untwisting pipe 82, and a dust collector 80. It is prepared as a simple configuration.

  The yarn joining nozzle 94 is disposed on the front side of the main body of the splicer device 14, and a yarn joining hole 90 is formed in the yarn joining nozzle 94. Further, an unillustrated jet outlet for jetting compressed air is formed inside the yarn joining hole 90, and a swirling airflow is generated inside the yarn joining hole 90 by the compressed air. .

  The yarn shifting lever 96, the clamp portion 97, and the yarn pressing lever 98 are all provided in pairs on the upper side and the lower side of the yarn joining nozzle 94. The yarn shifting lever 96 is configured to move the lower yarn guided by the lower yarn guide pipe 25 and the upper yarn guided by the upper yarn guide pipe 26 to the yarn joining nozzle 94. The clamp portion 97 is configured to be able to clamp a predetermined portion of the upper yarn and the lower yarn guided by the yarn joining nozzle 94. The yarn presser lever 98 is configured to press and fix the upper yarn and the lower yarn when the yarn is spliced by the yarn joining nozzle 94.

  The splicer device 14 is provided with an untwisting pipe 82 for the upper yarn end and the lower yarn end. The two untwisting pipes 82 are formed in an elongated cylindrical shape, and are arranged in parallel to each other with the longitudinal direction thereof directed in the front-rear direction of the splicer device 14. Two untwisting pipes 82 are arranged one above the other, and each has one end opened to the front of the splicer device 14. The opening end of the untwisting pipe 82 for the upper yarn end is disposed below the yarn joining nozzle 94, and the opening end of the untwisting pipe 82 for the lower yarn end is disposed above the yarn joining nozzle 94.

  Each untwisted pipe 82 is configured such that compressed air is ejected from a compressed air passage (not shown). Further, an air flow guide tube 89 is connected to an end portion of the untwisting pipe 82 on the back side of the device, and the air flow guide tube 89 converts an air flow generated by compressed air injected into the untwisting pipe 82 into the splicer device 14. It is possible to guide to the dust collector 80 arranged on the back side.

  The dust collector 80 is fixed to the main body of the splicer device 14 by an appropriate means such as a screw. The dust collector 80 includes a dust collection chamber 81, a yarn waste introduction port 83, a rod-shaped member 86, and a lid 87.

  The dust collection chamber 81 is formed inside a cylindrical casing, is configured in a substantially cylindrical shape, and is configured to be capable of generating a vortex rotating airflow therein. Specifically, the dust collector 80 is provided with a lint introduction port 83 for introducing an air flow in a substantially tangential direction of the cylindrical dust collection chamber 81. By blowing an air flow toward the lint introduction port 83, a vortex rotating air flow can be generated inside the dust collecting chamber 81. The airflow guide tube 89 guides the airflow toward the lint introduction port 83. Although there is no restriction | limiting in particular about the raw material of the dust collection chamber 81, If it comprises with transparent or semi-transparent resin etc., the accumulation amount etc. of the below-mentioned yarn waste can be confirmed from the outside, and it is suitable.

  As shown in FIG. 3, the rod-shaped member 86 is provided so that its axis substantially coincides with the center of a cylindrical dust collection chamber 81. Further, the rod-shaped member 86 is formed so as to have a circular cross section. The rod-shaped member 86 is provided so as to protrude upward from the bottom of the dust collecting chamber 81, the lower half is formed in a cylindrical shape with a uniform thickness, and the upper half is tapered (substantially conical). Is formed.

  The lid 87 includes an air bleeding filter 84 and a lint discharge opening 85. The lid portion 87 is attached through, for example, a screwing portion so as to cover an open portion formed in the upper portion of the dust collecting chamber 81, and can be removed by rotating. The air vent filter 84 is formed of, for example, a wire net-like filter that does not generate much air resistance and is rough enough to capture lint. The lint discharge opening 85 is opened in a circular shape at the center of the lid 87, and a suction pipe 95 is connected to the lint discharge opening 85 and sucked by an external suction device, whereby a dust collection chamber 81 is obtained. The yarn waste accumulated inside can be discharged to the outside. A part of the tip of the rod-shaped member 86 is partially inserted into the center of the lint discharging opening 85.

  Next, the operation at the time of yarn splicing of the splicer device 14 will be described. For example, when the yarn of the yarn supplying bobbin 21 is lost and a new bobbin is supplied, or when the clearer 15 detects the yarn defect and cuts the yarn with a cutter to remove the yarn defect, This is performed when it is necessary to connect the lower thread on the yarn feeding bobbin 21 and the upper thread on the package 30 side.

  In this case, the cradle 23 first raises the cradle 23 by a lift-up mechanism (not shown) to separate the package 30 from the winding drum 24. At the same time, a package brake mechanism (not shown) stops the rotation of the package 30 held by the cradle 23. When the winding of the package 30 is stopped, the splicing operation by the splicer device 14 is started.

  When the yarn splicing operation is started, the suction port 32 of the lower yarn guide pipe 25 captures the lower yarn at the position shown in FIG. 1 and then rotates upward about the shaft 33 to cause the lower yarn to enter the splicer device 14. To guide you. At substantially the same time, the upper thread guide pipe 26 rotates upwardly from the position shown in the drawing with the shaft 35 as the center, and the upper thread unwound from the package 30 reversed by a drum drive motor (not shown) is sucked into the suction mouth. 34. Subsequently, the upper thread guide pipe 26 rotates downward about the shaft 35 to guide the upper thread to the splicer device 14.

  As shown in FIG. 3, the upper yarn and the lower yarn guided to the splicer device 14 are brought together by the yarn gathering lever 96 and inserted into the yarn joining hole 90 of the yarn joining nozzle 94. At this time, the upper thread and the lower thread are respectively clamped by the clamp portion 97, the lower thread is introduced into the lower thread cutter 92, and the upper thread is introduced into the upper thread cutter 93. In FIG. 3 and subsequent figures, the lower thread is drawn with a broken line in order to distinguish the upper thread from the lower thread for easy understanding.

  Then, the upper thread and the lower thread are cut into a predetermined length by the cutters 92 and 93 to form a thread end. The remaining portion of the cut yarn is sucked and removed by the suction port 32 and the suction mouth 34.

  Almost simultaneously with the yarn cutting, compressed air is jetted from the compressed air passage 73 toward the inside of the untwisting pipe 82. Then, as shown in FIG. 4, the yarn end formed by the yarn cutting is sucked into the untwisting pipe 82. Then, the upper yarn and the lower yarn are untwisted by untwisting the fiber at the yarn end by the air flow inside the respective untwisting pipes 82. At this time, fine yarn waste 75 is generated and blown to the air flow.

  The yarn waste 75 blown into the air flow is introduced into the dust collection chamber 81 from the yarn waste introduction port 83 of the dust collector 80 through the airflow guide tube 89 connected to the untwisting pipe 82. At this time, since the air flow from the untwisting pipe 82 is introduced into the cylindrical dust collection chamber 81 from a substantially tangential direction, a vortex rotating air flow 74 is generated inside the dust collection chamber 81. As a result, according to the principle of the cyclone (powder separator), the yarn waste 75 is blown to the outer peripheral side by centrifugal force and is deposited in the lower part of the dust collecting chamber 81 by gravity. The clean air flow from which the yarn waste 75 is separated is discharged to the outside of the dust collecting chamber 81 through the air vent filter 84. At this time, the yarn waste 75 is entangled with the rod-shaped member 86, whereby the yarn waste can be efficiently collected in the dust collection chamber 81.

  When the yarn ends are untwisted, both the upper yarn end and the lower yarn end are pulled out from the untwisting pipe 82 by the yarn moving operation of the yarn moving lever 96 and the yarn holding operation of the yarn holding lever 98 as shown in FIG. Then, they are set in a state where they are overlapped with each other in the yarn joining hole 90 of the yarn joining nozzle 94. In this state, the compressed air is ejected from the ejection hole 72 into the yarn joining hole 90, thereby generating a swirling flow of the compressed air, causing the fibers of the upper yarn and the lower yarn to be entangled and twisted to perform the yarn joining. When the yarn splicing is completed, the operations of the levers 96 and 98 are released and the clamp of the yarn by the clamp portion 97 is released. At the same time, the cradle 23 is operated so that the package 30 contacts the winding drum 24, and the winding of the yarn is resumed.

  Next, the discharge of the yarn waste 75 accumulated in the dust collecting chamber 81 will be described. If the operation of the splicer device 14 is continued for a long period of time, fine yarn waste 75 is accumulated at the bottom of the dust collecting chamber 81. Eventually, the yarn waste 75 overflows from the yarn waste discharge opening 85. Therefore, it is necessary to discharge the yarn waste 75 to the outside of the dust collecting chamber 81 at an appropriate timing.

  In the present embodiment, the yarn waste 75 can be discharged by connecting the suction pipe 95 to the yarn waste discharge opening 85 by an operator or a maintenance worker. The suction pipe 95 is connected to a blower as a negative pressure source disposed in the blower box via a control valve (not shown). In this configuration, for example, when a control unit (not shown) opens the control valve for a predetermined time in response to an operator's operation, the yarn waste 75 inside the dust collecting chamber 81 is sucked out by the suction pipe 95 as shown in FIG. Discharged to the outside.

  In the present embodiment, a rod-shaped member 86 is disposed inside the dust collection chamber 81. Therefore, when the yarn waste 75 is accumulated to a certain extent, the yarn waste 75 is prevented from forming a large ball-shaped lump even if the yarn waste 75 is gathered and grows in a ring shape around the rod-like member 86. Therefore, even when the amount of accumulated yarn waste 75 is large, suction can be easily performed without clogging the yarn waste discharge opening 85 and the suction pipe 95, so that the frequency of suction by the suction pipe 95 can be reduced and maintenance can be performed. Work can be reduced. Further, since the rod-shaped member 86 is tapered toward the lint discharge opening 85, even the lint 75 that has grown in a ring shape and entangled with the rod-shaped member 86 can be easily removed from the rod-shaped member 86. It can be extracted and collected from the lint discharge opening 85.

  Further, since the above suction operation involves suction by a strong negative pressure source, there is a possibility of affecting the untwisting of the yarn end by the untwisting pipe 82 described above. In order to avoid this, the suction of the yarn waste 75 by the suction pipe 95 is preferably performed at a timing other than at the time of untwisting.

  On the other hand, when the yarn waste 75 is entangled or accumulated in a large amount, it may not be discharged by suction with the suction pipe 95. In such a case, the upper portion of the dust collection chamber 81 can be opened by removing the lid 87. As a result, the maintenance worker can easily clean the inside of the dust collection chamber 81, and can pick up and remove the yarn waste 75 by hand.

  Further, when the entire splicer device 14 is very dirty or when a failure occurs, the entire splicer device 14 can be removed by removing the bolts 88. Thereby, the whole can be cleaned or replaced with a new apparatus.

  As described above, the splicer device 14 of the present embodiment includes the dedicated dust collector 80 for collecting the yarn waste 75.

  As a result, the lint 75 does not scatter around and adhere to the machine base body or the package 30 of the winder unit 10, so that the work environment and package quality can be improved. Further, since the splicer device 14 includes the dust collector 80, a complicated dust collection path is not required, the apparatus is simplified, and the problem of clogging the yarn waste 75 in the middle of the dust collection path does not occur, thereby reducing maintenance work. can do.

  Further, in the splicer device 14 of the present embodiment, the dust collector 80 includes a dust collection chamber 81 configured in a substantially cylindrical shape, and generates a vortex rotating air flow 74 inside the dust collection chamber 81, thereby generating lint 75. Is recovered.

  Thereby, the yarn waste 75 can be efficiently collected in the dust collecting chamber 81 by the vortex rotating air flow 74.

  Further, the splicer device 14 of the present embodiment includes an untwisting pipe 82 in which a yarn end is introduced at the time of yarn joining and the yarn end is untwisted with compressed air. The dust collector 80 is provided with a yarn waste introduction port 83 for introducing the yarn waste 75 in a substantially tangential direction of the dust collection chamber 81, and the air flow from the untwisting pipe 82 generated by the injection of compressed air is yarn. The vortex rotating air flow 74 is generated by being blown to the waste introduction port 83.

  As a result, the yarn waste 75 generated at the time of yarn untwisting is directly introduced into the dust collecting chamber 81, so that dust collection becomes extremely easy. Further, since the vortex rotating air flow 74 is generated using the air flow from the untwisting pipe 82, the yarn waste 75 can be collected in the dust collecting chamber 81 without requiring a negative pressure source or the like.

  Further, in the splicer device 14 of the present embodiment, an air vent filter 84 is provided at one end in the axial direction of the substantially cylindrical dust collection chamber 81.

  As a result, scattering of the yarn waste 75 from the dust collecting chamber 81 can be prevented by the air vent filter 84, and at the same time, the vortex rotating air flow 74 can be smoothly discharged through the air vent filter 84. Therefore, it is possible to prevent the air flow including the yarn waste 75 from flowing backward to the untwisting pipe 82 side.

  Further, in the splicer device 14 of the present embodiment, a yarn waste discharge opening 85 for discharging the collected yarn waste 75 to the outside is provided at one end (upper end) in the axial direction of the substantially cylindrical dust collection chamber 81. It has been.

  Thereby, the yarn waste 75 collected in the dust collector 80 can be easily discharged to the outside through the yarn waste discharge opening 85.

  Further, in the splicer device 14 of the present embodiment, a rod-shaped member 86 having a circular cross section is provided at the center of the dust collection chamber 81.

  Accordingly, the yarn waste 75 can be collected in the central portion of the dust collecting chamber 81 while being entangled with the rod-shaped member 86. Accordingly, the collection of the yarn waste 75 from the dust collecting chamber 81 is facilitated.

  Further, in the splicer device 14 of the present embodiment, one end of the rod-shaped member 86 is tapered.

  As a result, the yarn waste 75 entangled around the rod-shaped member 86 is moved toward the tapered end portion and extracted, whereby the yarn waste 75 can be easily recovered.

  Further, the splicer device 14 of the present embodiment is configured such that one end side (upper end side) of the substantially cylindrical dust collection chamber 81 can be opened by removing the lid 87.

  Thereby, maintenance work such as cleaning the inside of the dust collecting chamber 81 can be easily performed.

  Further, the splicer device 14 of the present embodiment is detachable from the machine base (the panel 91) of the winder unit 10 with the dust collector 80 attached.

  Thereby, maintenance work, replacement of the splicer device 14 and the like can be easily performed. Further, since the splicer main body for performing the yarn splicing and the dust collector 80 can be handled as a whole, the winder unit 10 can be easily attached to and detached from the machine base.

  The automatic winder of this embodiment includes a plurality of winder units 10, and each winder unit 10 includes the splicer device 14.

  Thereby, since the lint 75 does not scatter and adhere to the package, a high-quality package can be manufactured.

  Further, the automatic winder of the present embodiment includes a blower box for discharging the yarn waste 75 collected by the dust collector 80 to the outside of the dust collector 80.

  Thereby, since the yarn waste 75 can be efficiently discharged to the outside of the dust collector 80, the maintenance work becomes easier.

  Although the preferred embodiment of the present invention has been described above, the above configuration can be changed as follows, for example.

  The shape of the dust collection chamber 81 is preferably a circular cross-sectional shape in order to smoothly generate a vortex rotating airflow, but is not limited to a columnar shape, and for example, the dust collection chamber is configured in a tapered shape (cylindrical shape). be able to. This is preferable because the centrifugal force increases as the vortex rotating airflow advances from the large diameter portion of the taper toward the small diameter portion, and the dust collection performance is improved. Further, the dust collection chamber can be formed in a hollow donut shape.

  The yarn waste discharging opening 85 and the air vent filter 84 can be changed to a configuration directly formed on a member constituting the dust collection chamber 81, for example, instead of the configuration provided in the lid portion 87.

  Further, the lint discharging opening 85 and the air vent filter 84 can be changed to a configuration provided at the bottom (lower portion) of the dust collection chamber 81, for example, instead of the configuration provided at the upper portion of the dust collection chamber 81. However, it is preferable that the air vent filter 84 is provided in the upper part of the dust collecting chamber 81 from the viewpoint of collecting the yarn waste in the lower part by the swirl airflow and discharging the air from the upper part.

  The yarn waste discharge opening 85 can be omitted. However, in this case, since the suction operation by the suction pipe 95 cannot be performed, part of the dust collecting chamber 81 is opened and the lint 75 is removed manually.

  The air vent filter 84 can be changed to a finer filter instead of a wire mesh configuration. However, it is preferable to use a filter having a low air resistance in order to prevent a reverse flow of the air flow toward the untwisting pipe 82.

  Instead of being made of resin, the lid 87 may be formed of an elastic body such as rubber, and may be changed to a configuration that is fixed by being attached to the dust collecting chamber 81 while being elastically deformed.

  The rod-shaped member 86 can be changed to, for example, a configuration having a cylindrical shape as a whole or a configuration having a conical shape as a whole, instead of the configuration having a cylindrical shape at the lower portion and a substantially conical shape at the upper portion. It is also possible to form in a tapered shape other than the conical shape.

  The rod-shaped member 86 can be omitted. However, from the viewpoint of entanglement of yarn waste and facilitating recovery and preventing ball waste growth of the yarn waste and avoiding clogging of the yarn waste discharge opening 85, a rod shape as in the above embodiment is used. A member 86 is preferably provided.

  The timing of the suction operation is not performed after the yarn waste is accumulated, but for example, suction may be performed every time when the yarn joining ends. Further, for example, the suction pipe 95 can be always connected to the yarn waste discharge opening 85, and the control valve can be automatically opened at the end of yarn joining to change the configuration to suck the yarn waste. If suction is automatically performed at the end of yarn joining in this way, yarn waste is not accumulated, and there is no fear of adversely affecting untwisting of the yarn end by suction, which is particularly preferable. In addition, when the lint discharge opening 85 of each of the plurality of winder units 10 is commonly connected to a single blower, if the control valve is provided for each winder unit 10, lint discharge is controlled for each winder unit 10. It is more preferable because it is possible.

  Instead of connecting the blower of the blower box of the automatic winder to the lint discharge opening 85, for example, it can be changed to connect a small negative pressure source that can be carried by a maintenance worker.

  The lid 87 can be changed to a configuration in which, for example, the lower portion (bottom) of the dust collection chamber is opened and the lid portion is disposed so as to close the open portion instead of the configuration arranged at the upper portion of the dust collection chamber. In this case, yarn waste accumulates on the lid portion that forms the bottom of the dust collecting chamber. Therefore, by opening the lid portion, the yarn waste can be dropped by its own weight and easily recovered.

  Although the above embodiment has been described with respect to an automatic winder, the scope of application of the present invention is not limited to this, and the present invention can also be applied to other yarn winding machines such as a configuration in which a spinning machine includes a splicer device with a dust collector. it can.
