Description

  The present invention relates to a splicer device cleaner that unwinds and twists a yarn end in the vicinity of a nozzle in a head and then entangles the yarn.

  Conventionally, splicers such as spun yarns have been used with a splicer device that superimposes the ends of two yarns and applies a compressed fluid such as air to the overlapped portion (see, for example, Patent Document 1). . In splicing with a splicer device, fiber dust is generated when splicing or cutting a yarn with a head. In a textile machine for producing spun yarn, a large number of spinning units are arranged and simultaneously spun. A track is provided along the arrangement of the spinning units, and a work carriage that moves on the track to maintain the spinning unit is also used. The yarn splicing device is provided in a work carriage, and the work carriage is also provided with a cleaner. The spinning unit that needs to be spliced due to yarn breakage or the like stops, and the splicing is performed by moving on the track to the position of the spinning unit where the work carriage is stopped. The cleaner sucks and removes fiber dust generated during yarn splicing and fiber dust generated by spinning. In the working carriage, the spinning unit is connected to a duct provided for the entire spinning machine for each position of each spinning unit, and suction force is also used for suction removal of fiber dust as well as capturing by suction of the yarn end. A cleaner performs the cleaning operation | work with respect to the whole inside of a work trolley (for example, refer patent document 2, 3).

  When the yarn splicing device is provided in the winding unit, a configuration is also disclosed in which a suction removal mechanism is provided around the air blowing portion of the yarn splicing (see, for example, Patent Document 4). However, this yarn splicing device is an aqua splicer that performs splicing by containing liquid in compressed air, and the object to be removed by suction is liquid.

  While a textile machine such as a spinning device having a large number of spinning units is a relatively large device, the frequency of occurrence of a situation requiring yarn splicing is relatively small. In a knitting machine, a knitted fabric is basically knitted with a single knitting yarn. Therefore, if the knitting yarn can be switched by piecing, the variety of knitted fabrics to be knitted can be increased. However, when the splicer device is applied for piecing in a knitting machine, it is necessary to efficiently suck and remove the generated fiber dust. When installing a splicer device in a knitting yarn supply path in a knitting machine, a cleaner for cleaning the splicer device is also required to be compact.

  The purpose of the suction removal mechanism disclosed in Patent Document 4 is to remove liquid such as water to prevent the liquid from splashing and to prevent a problem from occurring in an electronic component or a mechanical component. As a component for this purpose, it has a “shielding mechanism that regulates the scattering direction of compressed air and liquid” and a “suction mechanism that sucks compressed air and liquid and discharges them outside the machine”. The starting time of suction is simultaneously or slightly delayed with respect to the starting time.

  However, in a splicer device mounted on a knitting machine or the like, it is relatively easy to receive a supply of compressed air, but it is difficult to receive a suction force.

  An object of the present invention is to provide a splicer device that is equipped with a splicer device in a device that uses yarn, such as a knitting machine, and can efficiently suction and remove fiber dust even if the supply of suction force is not always sufficiently received. Is to provide a cleaner.

An electromagnetic valve that switches ON / OFF the suction of the air flow by the cleaning means;
A control unit for controlling the solenoid valve;
And a compressed air source for supplying the compressed air.

According to the present invention, the pressure of the air flow that occurs at the time of piecing and includes fiber dust blown out from the head including the compressed air blowing nozzle is attenuated, the direction of the air flow in which the pressure is attenuated is changed, and the direction is changed. The changed air flow is sucked to remove fiber dust. Rather than directly sucking the air flow blown from the head, the pressure is attenuated by the attenuating means, and the direction is changed by the changing means and then sucked, so even if the suction force cannot always be sufficiently received, It is possible to efficiently remove and remove fiber dust.

Also, to divert compressed air supplied to the nozzle in the head, since the suction removal of utilizing negative pressure fiber dust is generated around the compressed air flow, the compressed air supplied to the head, It can also be used to suck and remove fiber dust generated during yarn splicing. Even if the suction force cannot be supplied, the fiber dust can be efficiently suctioned and removed by using the compressed air supplied to the head that performs the splicing.

According to the present invention, the perforated inclined plate arranged in the flow path of the air blown out from the head has a plurality of holes, and can also serve as an attenuating means that allows a part of the air flow to pass and reduces the remaining pressure. Also, it can function as changing means for changing the direction of the remaining air flow by the inclination with respect to the flow path.

  Further, according to the present invention, the changing means changes so that the air flow flows, and the cleaning means sucks the air flow in the vicinity of the center of the rotating air flow, so that the air flow can be sucked efficiently. .

Moreover, according to this invention, since the cleaning means is provided with the suction port performed in the direction parallel to the central axis direction of the airflow to rotate, it can suction by reducing the pressure of the airflow.

  According to the invention, the cleaner of the splicer device includes a cleaner cover, a solenoid valve, a control unit, and a compressed air source. The cleaner cover is provided with a cleaning means and covers a surrounding space including at least a part of the splicer device. The electromagnetic valve switches the suction of the air flow by the cleaning means to ON / OFF, and the control unit controls the electromagnetic valve. Since the air source supplies compressed air, even if a splicer device is added to an existing knitting machine, etc., the air source is compact and efficiently removes the fiber dust generated during splicing. Diffusion can be prevented.

  FIG. 1 shows a schematic configuration of a cleaner 1 as an embodiment of the present invention. The cleaner 1 is provided in a splicer device 2 that performs yarn splicing. The splicer device 2 is provided in the flat knitting machine 3 and is used for switching by piecing while measuring a part of the knitting yarn used for knitting the knitted fabric. Such a splicer device 2 performs splicing in a splice nozzle 4 having a compressed air blowing nozzle. That is, the splice nozzle 4 serves as a head for piecing. In the vicinity of the splice nozzle 4, the suction yarn 5 is sucked in order to suck and introduce the knitting yarn used for the splicing into the splice nozzle 4 or to cut the end of the joined portion of the spliced knitting yarn. Is placed. The cleaner 1 is used for sucking and removing fiber dust generated during splicing from the splice nozzle 4 of the splicer device 2.

The cleaner 1 covers the periphery of the splicer device 2 where the splice nozzle 4 is provided with a cleaner cover 6. A perforated inclined plate 7 is disposed in a portion of the inner wall of the cleaner cover 6 where the air flow blown from the splice nozzle 4 first hits. The perforated inclined plate 7 has a plurality of holes and can function as a damping means for passing a part of the air flow to attenuate the pressure of the remaining part. Can be made to function as a changing means. A suction port 8 is provided in the cleaner cover 6. An inclined plate 9 is disposed around the suction port 8.

  In such an arrangement, the suction port 8 does not directly suck the compressed air blown from the splice nozzle 4 but sucks it at a remote position. Even if the suction amount is smaller than the amount to be blown out, the attenuated air is sucked, so that the suction can be sufficiently performed.

  The air sucked at the suction port 8 is sent into a dust box 10 provided in the flat knitting machine 3. A suction force for sucking air at the suction port 8 is generated by the suction nozzle 11. A similar suction nozzle 12 is also used to generate the suction force of the suction 5. An air flow is guided from the suction nozzles 11 and 12 to the dust box 10 via the duct pipes 13 and 14. A part of the compressed air is diverted to the suction nozzles 11 and 12 from a compressed air source that is supplied to the splice nozzle 4 via the compressed air pipe 15 and is supplied through the compressed air pipes 16 and 17, respectively. In each of the suction nozzles 11 and 12, compressed air is ejected inside, and negative pressure is generated by the ejected air.

That is, the blowout compressed air 20 blown to the left from the splice nozzle 4 is partly discharged as the outflow compressed air 21 by the perforated inclined plate 7, the pressure is attenuated, and the direction is changed upward as the attenuated compressed air 22. A suction port 8 is disposed above the cleaner cover 6, and an inclined plate 9 is disposed around the suction port 8. When the damped compressed air 22 hits the inclined plate 9, the direction is changed, and around the suction port 8, rotating compressed air 23 that rotates around the suction port 8 is formed. The suction port 8 sucks air in parallel to the central axis direction of the rotary compressed air 23. The perforated inclined plate 7 and the inclined plate 9 as the changing means are changed so that the air flow flows, and the suction port 8 as the cleaning means sucks the air flow near the center of the rotating air flow. The flow can be sucked efficiently. Moreover, since the cleaning means includes the suction port 8 that runs in a direction parallel to the central axis direction of the rotating compressed air 23 that is a rotating air flow, the cleaning means can perform suction while reducing the pressure of the air flow. The position of the suction port 8 is preferably near the center of the rotating air flow, but may be near the outer periphery of the rotating air flow.

  As described above, the intake air also uses the compressed air supplied from the air supply source. The compressed air supplied from the air supply source is diverted to the solenoid valves 31 and 32 controlled by the control unit 30, and the blowing from the splice nozzle 4 and the suction at the suction port 8 and the suction 5 are respectively turned on. / OFF control is possible.

  In the cleaner 1, the electromagnetic valves 31 and 32 also function as a diversion unit that diverts the compressed air supplied to the nozzles in the splice nozzle 4. When the compressed compressed air is introduced into the suction nozzles 11 and 12 as negative pressure generating means, a negative pressure is generated around the compressed air flow in the suction nozzles 11 and 12. The suction port 8 as a cleaning means uses the negative pressure generated by the suction nozzle 11 to suck and remove fiber dust, so that the compressed air supplied to the splice nozzle 4 is a fiber generated at the time of piecing. It can also be used to suck away dust. Even if the suction force cannot be supplied, the fiber dust can be efficiently suctioned and removed by using the compressed air supplied to the splice nozzle 4 for piecing.

  FIG. 2 shows an external configuration of the splicer device 2. FIG. 3 shows a state in which the cleaner cover 6 is attached to the splicer device 2 of FIG. In the splicer device 2 in the state shown in the drawing, at least one of the plurality of knitting yarns supplied from above can be selected by the yarn selection unit 41 and switched to the knitting yarn in use. The leading end of the knitting yarn that is in a standby state without being used is held by the yarn holding portion 42. Although the standby knitting yarn is on the front side of the separator 43, the knitting yarn in use is supplied downward from the back side of the separator 43. When the knitting yarn being used is switched to the knitting yarn selected by the yarn selection unit 41, the knitting yarn selected by the yarn selection unit 41 is drawn toward the back side of the separator 43. A yarn guide lever 44 is disposed on the back surface side of the separator 43, and the selected knitting yarn can be guided downward by the swivel displacement, and the knitting yarn in use can be moved to the front surface side of the separator 43. The knitting yarn guided downward by the yarn guide lever 44 is introduced into the splice nozzle 4. In the splicing nozzle 4, compressed air is blown onto the knitting yarn selected from the internal nozzles and the knitting yarn in use to perform piecing. At the time of yarn splicing, an air flow blows out from the blowout port 45. As shown in FIG. 3, the cleaner cover 6 is mounted so as to cover the outlet 45 of the splice nozzle 4.

The cleaner cover 6 including the inclined plate 9 as the changing means and the suction port 8 as the cleaning means are included. The attenuating means attenuates the pressure of the air flow blown from the head. The changing means changes the direction of the air flow whose pressure is attenuated by the damping means. The cleaning means sucks and removes the fiber dust by sucking the air flow whose direction is changed by the changing means. The cleaning means does not directly suck the air flow blown from the head, but attenuates the pressure by the damping means and changes the direction by the changing means before sucking, so that the suction force is not necessarily sufficiently received. Even if it is not, the suction and removal of fiber dust can be performed efficiently.

  FIG. 6 shows a schematic internal configuration of the suction nozzles 11 and 12 of FIG. The suction nozzles 11, 12 are each provided with a suction port 51 on one side of an approximately cylindrical casing 50 in the axial direction, a pressing port 52 in the middle, and an outflow port 53 on the other side in the axial direction. When compressed air is introduced into the pressing port, the compressed air is blown out to the outflow port 53 side, and a negative pressure can be generated at the suction port 51. The pressure of the compressed air supplied from the compressed air supply source may be about 490 kPa (5 kg weight per square centimeter), for example. Such compressed air may be supplied collectively to the entire factory, and in such a case, it can also be used for the cleaner 1. Moreover, it is also possible to provide a compressed air source such as a compressor for each flat knitting machine 3 or for each group.

  When the compressed air source is thus included, the cleaner 1 of the splicer device 2 includes the cleaner cover 6, the electromagnetic valve 32, the compressed air source, and the control unit 30. The cleaner cover 6 is provided with a suction port 8 as a cleaning means, and covers a surrounding space including at least a part of the splicer device 2. The electromagnetic valve 32 switches the suction of the air flow by the cleaning means to ON / OFF, and the control unit 30 controls the electromagnetic valve 32. Since the compressed air source supplies compressed air, even if the splicer device 2 is added to the existing flat knitting machine 3 or the like, the fiber dust generated at the time of piecing can be efficiently removed.
