Detailed Description

The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.

Referring to fig. 1 to 2, the present embodiment provides a duct connecting assembly 100 including a plurality of spinning units 2 arranged in parallel. The spinning machine 1 includes a yarn joining trolley (working trolley) 3, a blower case 80, and a motor case 5. The motor box 5 is provided with a machine control device (not shown) that controls the entire spinning machine 1. In a factory where the spinning machine 1 is installed, a worker passage extending in the arrangement direction of the spinning units 2 is provided on the yarn passage side of the spun yarn 10 with respect to the yarn joining cart 3 so that each spinning unit 2 can be monitored from the worker passage side.

As shown in fig. 1, each spinning unit 2 includes, in order from upstream to downstream, a drafting device 7, an air-jet spinning device 9, a yarn storage device 12, a waxing device 14, and a winding device 13. The draft device 7 and the air-jet spinning device 9 constitute a yarn feeding unit that feeds the spun yarn 10 to the winding device 13.

The drafting device 7 is arranged near the upper end of the housing 6 of the spinning machine 1. The fiber bundle 8 (see fig. 2) sent out from the draft is spun by the air-jet spinning device 9. The spun yarn 10 fed from the air-jet spinning device 9 passes through the yarn clearer 52, is further transported downstream by the yarn accumulating device 12, and is waxed by the waxing device 14. Then, the spun yarn 10 is wound by the winding device 13 to form a package 45.

The drafting device 7 drafts the sliver 15 into a fiber bundle 8. As shown in fig. 2, the draft device 7 includes four roller pairs: a back roller pair 16, a third roller pair 17, a middle roller pair 19 on which a belt 18 is mounted, and a front roller pair 20. The lower roller pairs 16, 17, 19 and 20 of each roller are driven by power from the chassis 5 or a separately provided drive source (not shown). The roller pairs 16, 17, 19 and 20 are driven at different rotational speeds, as a result of which the sliver 15 fed from the upstream side is drawn into a fiber bundle 8 and sent to the downstream air spinning device 9.

The air-jet spinning device 9 twists the fiber bundle 8 with a rotating air flow to produce a spun yarn 10. The air-jet spinning device 9 is provided with a fiber guide portion, a vortex generating nozzle, and a hollow guide shaft. The fiber guide unit guides the fiber bundle 8 sent out from the draft device 7 to a spinning chamber formed inside the air-jet spinning device 9. Swirl generating nozzles are provided around the path of the fiber bundle 8 to generate a swirl during spinning. The fiber end of the fiber bundle 8 in the spinning chamber is reversed and swirled by the swirling flow. The hollow guide shaft guides the spun yarn 10 from the spinning chamber to the outside of the air-jet spinning device 9.

A yarn storage device 12 is provided downstream of the open-end spinning device 9. The yarn accumulating device 12 has a function of applying a predetermined tension to the spun yarn 10, drawing it out of the air-jet spinning device 9, and causing spinning. The yarn 10 fed out from the air spinning device 9 stops at the time of yarn joining by the yarn joining carriage 3, and has a function of preventing the spun yarn 10 from slackening and a function of adjusting tension to fluctuate tension. The airflow on the winding device 13 side is not transmitted to the air-jet spinning device 9 side. As shown in fig. 2, the yarn storage device 12 includes a yarn storage roller 21, a yarn hanging member 22, an upstream guide member 23, a motor 25, and a downstream guide member 26.

The yarn hooking member 22 is configured to be engageable with (hooked on) the spun yarn 10, and by rotating integrally with the yarn accumulating roller 21 in a state of being engaged with the spun yarn 10, the spun yarn 10 can be wound around the outer peripheral surface of the yarn by the yarn accumulating roller 21.

The yarn accumulating roller 21 can accumulate the spun yarn 10 around the outer peripheral surface by a fixed amount. The yarn storage roller 21 is driven to rotate by a motor 25. The spun yarn 10 wound around the outer peripheral surface of the yarn accumulating roller 21 tensions the yarn accumulating roller 21 in accordance with the rotation of the yarn accumulating roller 21, and the spun yarn 10 on the upstream side of the yarn accumulating device 12 is pulled out. That is, the yarn accumulating device 12 applies a predetermined tension to the spun yarn 10 by rotating the yarn accumulating roller 21 in a state where the spun yarn 10 is wound around the outer peripheral surface at a predetermined rotation speed, and starts spinning from the spun yarn 10. The yarn 10 of the open-end spinning device 9 can be drawn at a predetermined speed and conveyed downstream at a predetermined speed.

By winding a predetermined amount of the spun yarn 10 around the outer peripheral surface of the yarn accumulating roller 21, a contact area between the yarn accumulating roller 21 and the spun yarn 10 can be ensured. The yarn accumulating roller 21 can hold and pull the spun yarn 10 with a sufficient force, and the yarn accumulating device 12 can hold the spun yarn 10 at a stable speed from the air-jet spinning device 9 without causing a slip or the like.

An upstream guide 23 is arranged upstream of the storage roll 21. The upstream guide 23 appropriately guides the spun yarn 10 to the outer peripheral surface of the yarn storage roller 21. The upstream guide 23 prevents the twist of the spun yarn from being transmitted to the downstream side of the upstream guide 23 from the yarn 10 of the air-jet spinning device 9.

The clearer 52 is provided at a position on the front side (worker passage side) of the housing 6 of the spinning machine 1 between the open-end spinning device 9 and the yarn storage device 12. The open-end spinning device 9 passes through the yarn clearer 52 before being taken up by the yarn storage device 12. The clearer 52 monitors the thickness of the traveling spun yarn 10 and/or foreign matter contained in the spun yarn, and when detecting a yarn defect of the spun yarn 10, detects transmission of a yarn defect detection signal to the spinning unit 2, and transmits the signal to the unit-side control section 53 provided.

Upon receiving the yarn defect detection signal, the unit-side control section 53 immediately stops the ejection of the compressed air from the whirling airflow generating nozzle of the air-jet spinning device 9. Twisting of the fiber bundle 8 is stopped, and introduction of the fiber bundle 8 into the air-jet spinning device 9 is also stopped. Then, the spun yarn 10 is cut while separating the continuous state of the fiber in the air-jet spinning device 9. After that, the unit-side control unit 53 further stops the draft device 7 and the like.

The unit-side control unit 53 transmits a control signal to the carriage-side control unit 38 of the yarn joining carriage 3 to move the yarn joining carriage 3 in front of the spinning unit 2. The air-jet spinning device 9 and the like are driven again to splice the splicer carriage 3 and rewind it. At this time, the yarn accumulating device 12 accommodates the yarn 10 continuously fed out from the air-jet spinning device 9 from the spinning resumption of the air-jet spinning device 9 to the winding resumption of the package 45. The spun yarn 10 is accumulated in the roller 21 to be free from slack.

As shown in fig. 1 and 2, the yarn joining cart 3 has a lower side of a housing 6 in which a draft device 7, an air-jet spinning device 9, and the like are arranged in an arrangement direction of the spinning units in a height direction of the bed.

The travel space is located below the draft device 7, the air-jet spinning device 9, and the like.

The yarn joining cart 3 includes a splicer 43, a suction pipe 44, and a suction unit 46. When a yarn break or a yarn breakage occurs in a certain spinning unit 2, the yarn joining cart 3 travels along the rail 41 to the spinning unit 2 and stops. The suction pipe 44 sucks and catches the yarn end fed out from the air-jet spinning device 9, and guides the yarn end to the splicer 43 while rotating in the vertical direction around the axis. The suction unit 46 sucks and catches a yarn end from the package 45 supported by the winding device 13, and guides the yarn end to the splicer 43 while rotating vertically around the axis, and the splicer 43 splices the guided yarn end.

A unit-side communication unit (first communication unit) 60 for performing optical communication is provided in the housing 6 at a position facing the joint carriage 3. Further, the joint carriage 3 is provided with a carriage-side communication unit (second communication unit) 30 for performing optical communication. The unit-side communication unit 60 and the cart-side communication unit 30 perform optical communication (non-contact communication), and exchange information (spinning unit number identification and the like) between the spinning unit 2 and the yarn splicing cart 3.

As shown in fig. 2, the yarn splicing cart 3 includes a detection sensor S for detecting the position of the spinning unit 2. The detection sensor S is disposed, for example, at the center portion (reference position) in the traveling direction of the joint carriage 3. The position of the detection sensor S is not particularly limited as long as it can detect the sensor detection means SD described later.

A waxing device 14 is provided downstream of the yarn storage device 12, and the waxing device 14 applies wax to the spun yarn 10 traveling from the yarn storage device 12 to the winding device 13.

The winding device 13 includes a cradle arm 71 swingably supported about a support shaft 70. The cradle arm 71 rotatably supports the bobbin 48 for winding the spun yarn 10.

The winding device 13 further comprises a winding drum 72 and a traverse device 75. The winding drum 72 can be driven in contact with the outer peripheral surface of the spool 48 or the outer peripheral surface of the package 45. The traverse device 75 includes a traverse guide 76 engageable with the spun yarn 10. The winding device 13 rotates by bringing the package 45 into contact with the winding drum 72 by driving the winding drum 72 by a motor (not shown), and at the same time reciprocates the traverse guide 76 by a driving device (not shown), so that the spun yarn 10 is wound around the package 45 while spinning the yarn 10.

During communication between the first communication unit 60 and the second communication unit 30, the lid 32 intersects a straight line connecting the first communication unit 60 and the second communication unit 30. The lid 32 is disposed between the first communication unit 60 and the second communication unit 30. The first communication unit 60 and the second communication unit 30 communicate through the lid 32.

The spray nozzles of the first nozzle 35a and the spray nozzles of the second nozzle 35b are installed facing opposite sides. The second nozzle 35b is, for example, branched from the first nozzle 35a, and the first nozzle 35a and the second nozzle 35b are integrally provided. The first nozzle 35a blows air to the coating layer 32 in a direction opposite to the yarn path of the spun yarn 10. The second nozzle 35b blows air to the side of the yarn path of the spun yarn 10.

A switching unit (cleaning unit) 37 is connected to the mouthpiece 35 via a duct 36, and compressed air from an air supply unit 81 is supplied to the duct 36. The switching unit 37 switches the air supply from the air supply unit 81. The air supply unit 81 to the mouthpiece 35 and cuts off the air supply. The yarn joining cart 3 may be provided with an air supply unit in addition to blowing compressed air from the blowing nozzle 35 from an air supply unit 81 provided in the blower case 80.

The yarn splicing cart 3 performs at least one of cart-side control of travel control of the yarn splicing cart 3, control of communication with the spinning unit 2 using the first communication unit 30, and yarn splicing control. When a yarn breakage or a thread breakage occurs in a certain spinning unit 2, the machine control device outputs a movement control signal for moving the spinning unit 2 to the yarn splicing cart 3, and the yarn splicing cart 3 is operated to the spinning unit 2 as an operation target. When the detection sensor S (reference position) of the yarn joining cart 3 passes through the sensor detection means SD (reference position) of the spinning unit 2, the cart-side control section 38 determines that the spinning unit 2 passes. Further, the second communication unit 38 controls the switching unit 37, and switches between the supply of air from the air supply unit 81 to the mouthpiece 35 and the interruption of the air supply.

Specifically, the carriage-side control section 38 is configured to rotate the spinning unit 2 before the spinning unit 2 in which the yarn joining carriage 3 operates a predetermined number of times (in the present embodiment, the spinning unit 2 is immediately rotated).

That is, in the present embodiment, when the sensor detection unit SD of the next spinning unit 2 of the target spinning unit 2 is detected after the detection sensor S detects the sensor detection unit SD (the adjacent spinning unit 2), the cart-side control section 38 controls the switching section 37 so that the air is blown to the waxing device 14 through the second nozzle 35b and the yarn splicing is stopped before the yarn splicing cart 3 reaches the target spinning unit 2. At this time, in the present embodiment, since the first nozzle 35a and the second nozzle 35b are integrally provided, air is also blown from the first nozzle 35a toward the lid 32.

In the cleaning unit, before the yarn joining cart 3 passes through the spinning unit 2 adjacent to the target spinning unit 2, and in the target spinning unit 2, in the spinning machine 1, before the first communication unit 60 and the second communication unit 30 start communication, the cotton lint accumulated on the first communication unit 30 can be cleaned and removed by the cleaning unit. Therefore, in the spinning machine 1, the communication between the first communication unit 60 and the second communication unit 30 can be reliably performed, and a problem that the yarn joining cart 3 cannot recognize the spinning unit 2 as the operation target can be prevented. As described above, in the spinning machine 1, the occurrence of defects caused by cotton wool can be prevented.

In the present embodiment, the cleaning unit is provided on the yarn joining cart 3. Therefore, in the spinning machine 1, the cleaning unit may be provided only on the yarn joining dolly 3, and the structure can be simplified as compared with a configuration in which a cleaning unit is provided in each spinning unit 2.

In the present embodiment, when the detection sensor S of the yarn joining cart 3 detects the sensor detection means SD of the spinning unit 2, the cart-side control portion 38 determines that the spinning unit 2 has passed based on the value. The tray-side communication unit 30 is cleaned as a result of the determination. With such a configuration, in the spinning machine 1, it is possible to recognize that the yarn splicing cart 3 has passed through the spinning unit 2, and the cleaning unit can perform cleaning at an appropriate timing.

In the present embodiment, before the yarn joining carriage 3 operates in the target spinning unit 2, the carriage-side control unit 38 controls the switching unit 37 to clean the waxing device 14. With this configuration, the apparatus shown in fig. 1 of the spinning machine can remove lint and/or wax deposited on the waxing device 14. In the spinning machine 1, since the waxing device 14 is cleaned before the operation of the yarn joining cart 3, the blowing of air onto the yarn to be spun is prevented. Therefore, the spun yarn 10 can be prevented from falling off from the waxing device 14.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
