Description

Yarn winding system

Technical Field

One aspect of the present disclosure relates to a yarn winding system.

Background

A yarn winding system is known, which includes: a spinning machine including a plurality of spinning units for forming yarn and winding the yarn around a bobbin to form a yarn-feeding bobbin; a yarn winding machine including a plurality of winding units for unwinding a yarn from a yarn supplying bobbin and winding the yarn into a package; and a transport device that transports the yarn feeding bobbin from the spinning machine to the yarn winding machine and transports the used yarn feeding bobbin from the yarn winding machine to the spinning machine. An example of such a yarn winding system is disclosed in patent document 1. In patent document 1 (japanese patent application laid-open No. 6-191734), spun yarn (yarn-feeding bobbin) formed in a plurality of spinning machines (spinning machines) is fed to one yarn winding machine (winding machine), and a cross-wound bobbin (package) is formed in the one yarn winding machine.

In recent years, with the improvement of the manufacturing capability of yarn feeding bobbins in a spinning machine, there is a demand for improving the manufacturing capability of packages in a yarn winding machine. Therefore, it is conceivable to increase the number of winding units of the yarn winding machine included in the conventional yarn winding system to improve the productivity. However, considering restrictions such as the transport capacity of the yarn supplying bobbin in the yarn winding machine and the suction capacity of the blower provided in the yarn winding machine, it is not possible to cope with the restrictions by simply increasing the number of winding units provided in the yarn winding machine. In addition, there are the following desires in addition to the above-described desire: even in the event of a failure of the yarn winding machine for some reason, the possibility of complete shut down of the operation of the yarn winding system is reduced.

An embodiment will be described below with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and duplicate descriptions are omitted. For convenience of explanation, fig. 1, 2, 6, and 7 set the X-axis, Y-axis, and Z-axis orthogonal to each other. In the following description, the following may be mentioned: as shown in fig. 1, the front side when the yarn winding system 1 is viewed from the front (Y-axis direction) is referred to as the front, the rear side is referred to as the rear, the left side is referred to as the left side, and the right side is referred to as the right side. That is, there are cases where: the Y-axis direction is referred to as the front-rear direction, the X-axis direction is referred to as the left-right direction, and the Z-axis direction is referred to as the vertical direction.

As shown in fig. 1 and 2, the yarn winding system 1 includes one spinning machine 3, two (a plurality of) automatic winder (yarn winding machines) 4, and a conveying device 5. In the yarn winding system 1 of the present embodiment, a larger number of automatic winders 4 than the number of spinning machines 3 are connected by the conveying device 5.

The spinning machine 3 generates a yarn Y2 from the roving Y1, and winds the yarn Y2 around the bobbin B to form a yarn feeding bobbin 11 (see fig. 5C). The roving bobbin 10 used in the spinning frame 3 is supplied from a roving frame (not shown) that generates a roving Y1 from a sliver, and winds the roving Y1 around a bobbin B0 (see fig. 3) to form the roving bobbin 10.

The spinning machine 3 includes: a machine control device 31 for controlling the operation of the spinning machine 3; and a plurality of spinning units 32 forming yarn feeding bobbins 11. The machine control device 31 includes a display portion 31a such as a display and an operation portion 31b such as an input key. The display unit 31a displays the operation state of each spinning unit 32. The operation unit 31b is a part for setting the operation conditions of each spinning unit 32 by an operator.

As shown in fig. 3, each of the plurality of spinning units 32 includes a roving supply unit 36, a drafting device 33, and a twisting device 34. The plurality of spinning units 32 are arranged along one direction. Hereinafter, the direction in which the plurality of spinning units 32 are arranged is referred to as an arrangement direction D1. The spinning machine 3 of the present embodiment has a plurality of spinning units 32 arranged in the arrangement direction D1 on the front side and the rear side of the entire machine frame.

The roving supply unit 36 supports the roving bobbin 10 in which the roving Y1 is wound around the bobbin B0. The draft device 33 has a rear roller pair 331, a middle roller pair 332, and a front roller pair 333. In the draft device 33, the rear roller pair 331, the middle roller pair 332, and the front roller pair 333 rotate at a predetermined speed ratio, and thereby the roving Y1 unwound from the roving bobbin 10 is drafted.

The rear roller pair 331 has a bottom roller 331a and a top roller 331b, and is disposed so as to face each other across the traveling path of the roving Y1. A 1 st drive motor 331c is connected to the bottom roller 331a via an output shaft, not shown, disposed across the plurality of spinning units. The middle roller pair 332 has a bottom roller 332a and a top roller 332b, and is disposed so as to face each other across the traveling path of the roving Y1. A belt is respectively supported on the bottom roller 332a and the top roller 332 b. A 2 nd drive motor 332c is connected to the bottom roller 332a via an output shaft disposed across a plurality of spinning units, not shown. The front roller pair 333 includes a bottom roller 333a and a top roller 333b, and is disposed so as to face each other across the traveling path of the roving Y1. A 3 rd drive motor 333c is connected to the bottom roller 333a via an output shaft disposed across a plurality of spinning units, not shown.

Examples of the 1 st drive motor 331c, the 2 nd drive motor 332c, and the 3 rd drive motor 333c are servo motors. The 1 st drive motor 331c, the 2 nd drive motor 332c, and the 3 rd drive motor 333c each have rotary encoders, not shown, and are independently controlled by the machine control device 31 via a servo motor drive circuit and a servo driver.

Twisting device 34 has spindle 341, ring plate 342, ring 343, and bead ring 344. Spindle 341 holds bottom Ba of bobbin B with top Bb of bobbin B facing upward, and rotates bobbin B. The ring plate 342 is movable in the axial direction of the bobbin B. Ring 343 is secured to ring plate 342. The bead ring 344 is supported on the ring 343 and is movable along the ring 343.

In the twisting device 34, the roving Y1 drawn in the drawing device 33 is inserted into a gap between the ring 343 and the bead ring 344, and an end of the roving Y1 is fixed to the bobbin B. When the spindle 341 rotates the bobbin B in this state, the bead ring 344 moves along the ring 343 so as to be pulled by the roving Y1. At this time, the ring plate 342 reciprocates within a predetermined range along the axial direction of the bobbin B and gradually moves from the bottom Ba side to the top Bb side. In the twisting device 34, the rotation of the bead ring 344 is made slower than the rotation of the bobbin B, whereby the roving Y1 is twisted to produce the yarn Y2, and the yarn Y2 is wound around the bobbin B to form the yarn feeding bobbin 11.

The spinning machine 3 having the plurality of spinning units 32 configured as described above is configured as a so-called one-shot type. That is, the spinning machine 3 stores a plurality of empty bobbins 13 transported from the automatic winder 4 by the transport device 5 in advance, and sets the empty bobbins 13 in each spinning unit 32 at once to start winding of the yarn at once. When the yarn winding is completed in each spinning unit 32 to form the yarn feeding bobbin 11, the spinning machine 3 drops (doffs) all the yarn feeding bobbins 11 at once. Then, the spinning machine 3 pulls out the empty bobbin 13 stored therein from the tray 9 (to be discussed later in detail) and sets it again in each spinning unit 32, and instead sets the yarn feeding bobbin 11 after doffing in the tray 9.

The automatic winder 4 winds the yarn Y2 from the yarn supplying bobbin 11 to form a package 15. As shown in fig. 1 and 2, the automatic winder 4 includes a machine control device 41 that controls the operation of the automatic winder 4, and a plurality of winding units 42 that form the packages 15.

In the present embodiment, as shown in fig. 2, two automatic winders 4, 4 are arranged at both ends of one spinning frame 3 in the arrangement direction D1. One spinning frame 3 and two automatic winder 4, 4 are arranged along the arrangement direction D1 of the spinning unit 32. That is, the single spinning frame 3 and the two automatic winders 4, 4 are arranged in a straight line along the arrangement direction D1. Further, as discussed in detail, the arrangement direction D1 of the plurality of spinning units 32 coincides with the arrangement direction of the plurality of winding units 42 in the X-axis direction. Later, there are cases where: the automatic winder 4 disposed on the left end side of the spinning frame 3 in the arrangement direction D1 is referred to as "left automatic winder 4A", and the automatic winder 4 disposed on the right end side of the spinning frame 3 in the arrangement direction D1 is referred to as "right automatic winder 4B".

The machine control device 41 includes a display portion 41a such as a display and an operation portion 41b such as an input key. The display 41a displays the operation state of each winding unit 42 and the like. The operation unit 41b is a part for setting the operation conditions of the respective winding units 42 by an operator. The machine control device 41 also controls the operation of the conveying device 5, which will be described later in detail.

As shown in fig. 4, each of the plurality of winding units 42 includes a winding device 43, a tension applying device 44, a yarn monitoring device 45, an upper yarn catching device 46, a lower yarn catching device 47, a yarn joining device 48, and a unit control section 49.

The winding device 43 has a cradle 43a and a winding drum 43b. Cradle 43a supports package 15. The winding drum 43b traverses the yarn Y2 and rotates the package 15. Thereby, the yarn Y2 is wound from the yarn supplying bobbin 11 set at the predetermined position to form the package 15. The tension applying device 44 applies a predetermined tension to the yarn Y2 advancing from the yarn feeding bobbin 11 to the package 15.

The yarn monitoring device 45 monitors the advancing yarn Y2 to detect yarn defects (thickness abnormality of the yarn Y2, contamination of foreign matter into the yarn Y2, and the like). In the case where a yarn defect is detected, the yarn Y2 is cut by a cutter provided separately. When the yarn Y2 is cut, the upper yarn catching device 46 catches the yarn end of the yarn Y2 on the package 15 side and guides the yarn end to the yarn joining device 48. When the yarn Y2 is cut, the lower yarn catching device 47 catches the yarn end of the yarn Y2 on the yarn feeding bobbin 11 side and guides the yarn end to the yarn joining device 48. The yarn joining device 48 connects the yarn ends guided by the upper yarn catching device 46 and the lower yarn catching device 47 to each other.

The unit control unit 49 controls operations of the winding device 43, the tension applying device 44, the yarn monitoring device 45, the upper yarn catching device 46, the lower yarn catching device 47, the yarn splicing device 48, and the like in the winding unit 42. For example, the unit control unit 49 cuts the thick thread portion of the yarn feeding bobbin 11 based on the information acquired by the yarn monitoring device 45, and controls the yarn joining device 48 so as to connect the yarn end of the yarn Y2 on the yarn feeding bobbin 11 side after the cutting to the yarn end of the yarn Y2 on the package 15 side.

The transport device 5 transports yarn supply bobbins 11 formed in one spinning frame 3 to the two automatic winders 4 and 4, respectively, and transports empty bobbins 13, which are used yarn supply bobbins 11 after being used in the two automatic winders 4 and 4, respectively, to the spinning frame 3. The so-called empty bobbin 13 here includes: bobbin B in a state of not winding yarn Y2; and a bobbin (defective bobbin) in which the yarn Y2 is wound around the bobbin B, but the winding amount is smaller than the winding amount of the bobbin B (full-tube yarn feeding bobbin 11) in which the predetermined amount of the yarn Y2 is wound as supplied from the spinning machine 3.

The transport device 5 transports the yarn feeding bobbin 11 and the empty bobbin 13 in a state of being placed on the tray 9 as shown in fig. 5A. The tray 9 has: a disk-shaped base portion 91; a protruding portion 92 protruding upward from the base portion 91; and a pin 93 protruding further upward from the protruding portion 92. The yarn supplying bobbin 11 shown in fig. 5C (including the ready-to-use yarn supplying bobbin 11 shown in fig. 5D) and the empty bobbin 13 shown in fig. 5B are attached to the tray 9 with one end of the bobbin B facing upward by inserting the pin 93 into the bottom Ba of the bobbin B. In other words, the tray 9 is configured to be capable of being placed in an upright state in which the axial direction of the bobbin B is in the vertical direction.

As shown in fig. 2, the conveying device 5 is configured by a plurality of conveying sections (first to sixth conveying sections 61 to 66) as shown later. The plurality of conveying sections (first to sixth conveying sections 61 to 66) form one closed-loop conveying path. That is, the conveying device 5 forms a closed loop conveying path between the single fine spinning machine 3 and the two automatic winders 4, 4. Each of the plurality of conveying units 61 to 66 may be appropriately constituted by a known structure including: a guide groove formed by the guide plate; a conveyor belt or a round belt arranged below the guide groove along the guide groove; and a driving device for driving the conveyor belt or the round belt. The respective conveying sections 61 to 66 convey the tray 9 on which the yarn feeding bobbin 11 and the empty bobbin 13 are placed by disposing the tray 9 in the guide groove.

Next, a description will be given of a conveying section for conveying the yarn feeding bobbin 11 formed in one of the spinning frames 3 to the right-side automatic winder 4B, and conveying the empty bobbin 13, which is the used yarn feeding bobbin 11 after use in the right-side automatic winder 4B, to the spinning frame 3. The transport units are arranged in the order of the first transport unit 61, the second transport unit (first storage unit) 62, and the third transport unit 63 along the transport direction of the yarn feeding bobbin 11 from the spinning frame 3 to the right-side automatic winder 4B. The fourth conveying unit 64, the fifth conveying unit 65, and the sixth conveying unit 66 are arranged in this order along the conveying direction of the empty bobbin 13 from the right automatic winder 4B to the spinning frame 3.

The first conveying section 61 is provided below the spinning units 32 arranged at the rear side of the machine frame of the spinning machine 3 along the arrangement direction D1 of the spinning units 32. The first conveying unit 61 feeds out the yarn feeding bobbin 11 supplied to the first conveying unit 61 toward the right automatic winder 4B in the collective doffing of the spinning units 32 arranged at the rear side of the machine frame of the spinning machine 3, and feeds out the empty bobbin 13 supplied from the left automatic winder 4A to the lower side of the spinning units 32 arranged at the rear side of the machine frame of the spinning machine 3.

The second conveying unit 62 is provided between the machine outlet of the spinning frame 3 and the machine inlet of the right automatic winder 4B. The second conveying unit 62 conveys the yarn feeding bobbin 11 fed from the spinning frame 3 to the right automatic winder 4B. The second transport unit 62 temporarily stores the yarn feeding bobbin 11 transported from the spinning frame 3, and adjusts the timing of feeding the yarn feeding bobbin 11 to the right of the automatic winder 4B. A stopper or the like, not shown, is provided at the most downstream portion of the second conveying portion 62, and the feeding of the yarn feeding bobbin 11 to the right automatic winder 4B is controlled by the station control device 41. The second conveying unit 62 is provided with a head-finding device 51.

The yarn end Y21 of the yarn Y2 is drawn out by the yarn-feeding bobbin 11 conveyed by the rightward automatic winder 4B by the yarn-finding device 51.

The fourth conveying unit 64 is provided on the front side of the right automatic winder 4B along the arrangement direction of the winding units 42. The fourth conveying unit 64 conveys the empty bobbin 13 from each winding unit 42 of the right automatic winder 4B to the front side of the machine and to the machine outlet (fifth conveying unit 65) of the right automatic winder 4B.

The fifth conveying unit 65 is provided between the machine outlet of the right automatic winder 4B and the machine inlet (sixth conveying unit 66) of the spinning frame 3. The fifth transport unit 65 temporarily stores the empty bobbin 13 transported from the right automatic winder 4B, and adjusts the timing of supplying the empty bobbin 13 to the spinning frame 3. A stopper or the like, not shown, is provided at the most downstream portion of the fifth conveying unit 65, and the supply of the empty bobbin 13 to the spinning machine 3 is controlled by the machine control device 41. In the case where the yarn Y2 remains on the used yarn feeding bobbin 11 discharged from the right automatic winder 4B, a processing device (not shown) may be provided in the fifth conveying section 65, and the processing device may remove the yarn Y2 to become the empty bobbin 13.

The sixth conveying section 66 is provided below the spinning units 32 arranged on the front side of the machine frame of the spinning machine 3 along the arrangement direction D1 of the spinning units 32. The sixth conveying unit 66 feeds out the yarn feeding bobbin 11 supplied to the sixth conveying unit 66 toward the left automatic winder 4A in the collective doffing of the spinning units 32 arranged on the front side of the machine frame of the spinning machine 3, and feeds out the empty bobbin 13 supplied from the right automatic winder 4B to the lower side of each spinning unit 32.

The conveying device 5 may form a circulation path for circulating the yarn feeding bobbin 11 and the empty bobbin 13 between the second conveying portion 62 and the fifth conveying portion 65. The circulation path may be configured to convey the yarn feeding bobbin 11, on which the yarn Y2 is left, or the tray 9 on which the bobbin B is not placed, to the fifth conveying unit 65, or to convey the yarn feeding bobbin 11, on which the yarn Y2 is not left, to the second conveying unit 62, after the yarn feeding bobbin 11 is not subjected to the yarn feeding processing or the yarn feeding processing in the second conveying unit 62 is not subjected to the yarn feeding processing, or the tray 9 may be removed from the fifth conveying unit 65, and the yarn feeding bobbin 13 may be conveyed to the second conveying unit 62 in a new state.

Next, a description will be given of a conveying section for conveying the yarn feeding bobbin 11 formed in one of the spinning machines 3 to the left-side automatic winder 4A and conveying the empty bobbin 13 used in the left-side automatic winder 4A to the spinning machine 3. The transport units are arranged in the order of the sixth transport unit 66, the second transport unit 62, and the third transport unit 63 in the transport direction of the yarn feeding bobbin 11 from the spinning frame 3 to the left automatic winder 4A. The fourth conveying unit 64, the fifth conveying unit 65, and the first conveying unit 61 are arranged in this order in the conveying direction of the empty bobbin 13 from the left automatic winder 4A to the spinning frame 3. In addition, since the first to sixth conveying units 61 to 66 are as described above (there are cases where there are differences in the conveying direction), detailed description thereof is omitted.

In the spinning machine 3 of the present embodiment, the plurality of spinning units 32 belong to any one of two different groups. Specifically, the spinning machine 3 has a group of spinning units 32 (spinning units belonging to the first group) arranged on the rear side of the machine and a group of spinning units 32 (spinning units belonging to the second group) arranged on the front side of the machine. The above two groups of spinning units 32 are also groups of spinning units 32 that perform doffing simultaneously, respectively.

The conveying device 5 conveys the yarn feeding bobbin 11 from the group of spinning units 32 arranged at the rear side of the machine frame of the spinning machine 3 to the right-side automatic winder 4B, and conveys the empty bobbin 13 from the right-side automatic winder 4B to the group of spinning units 32 arranged at the front side of the machine frame of the spinning machine 3. The transport device 5 transports the yarn feeding bobbin 11 from the group of spinning units 32 arranged on the front side of the frame of the spinning frame 3 to the left automatic winder 4A, and transports the empty bobbin 13 from the left automatic winder 4A to the group of spinning units 32 arranged on the rear side of the frame of the spinning frame 3.

Next, the transport operation of the yarn feeding bobbin 11 formed in the spinning unit 32 arranged at the rear side of the frame of the spinning machine 3 will be described. The spinning units 32 arranged at the rear side of the frame of the spinning machine 3 simultaneously pull out the plurality of empty bobbins 13, which are transported from the left automatic winder 4A and stored in the first transport unit 61, from the tray 9 and set at predetermined positions, respectively, so that winding of the yarn Y2 is simultaneously started. When the yarn Y2 is wound in each spinning unit 32 to form the yarn feeding bobbin 11, the spinning machine 3 drops (doffs) all the yarn feeding bobbins 11 arranged at the rear side of the machine frame of the spinning machine 3 at once. The spinning machine 3 simultaneously extracts the empty bobbins 13, which are transported from the automatic winder 4A on the left side of the spinning machine 3 and stored in the first transport unit 61, from the tray 9 again and sets them at predetermined positions, and instead, simultaneously sets the yarn feeding bobbins 11 after doffing on the tray 9.

The yarn feeding bobbin 11 set to the tray 9 together is conveyed to the second conveying section 62. The yarn feeding bobbin 11 fed to the second feeding section 62 is temporarily stored (stored) in a part of the section of the second feeding section 62, and the feeding timing of the yarn feeding bobbin 11 to the right automatic winder 4B (third feeding section 63) is adjusted. In the second conveying section 62, the yarn-feeding bobbin 11 is subjected to the yarn-feeding process by the yarn-feeding device 51. When the empty bobbin 13 is discharged from the winding unit 42 in the right automatic winder 4B (when the second conveying unit 62 receives a supply request signal supplied from the right automatic winder 4B), the second conveying unit 62 sends the yarn feeding bobbin 11 subjected to the yarn changing process to the third conveying unit 63 toward the winding unit 42.

The yarn feeding bobbin 11 is fed to the winding unit 42 by the third feeding section 63 fed with the yarn feeding bobbin 11 from the second feeding section 62. The winding unit 42 to which the yarn feeding bobbin 11 is supplied winds the yarn Y2 wound around the yarn feeding bobbin 11 to form the package 15. When the yarn Y2 is wound from the yarn feeding bobbin 11, the winding unit 42 discharges the used yarn feeding bobbin 11 as the empty bobbin 13. The empty bobbin 13 discharged from the winding unit 42 is discharged from the right automatic winder 4B by the fourth conveying unit 64, and is conveyed to the fifth conveying unit 65.

The fifth conveying unit 65 feeds the empty bobbin 13 conveyed from the fourth conveying unit 64 to the sixth conveying unit 66, and the sixth conveying unit 66 supplies the empty bobbin 13 to the spinning units 32 arranged on the front side of the machine frame of the spinning machine 3. The fifth conveying unit 65 may temporarily store (store) the empty bobbin 13 in a part of the section of the fifth conveying unit 65, and adjust the timing of supplying the empty bobbin 13 to the spinning machine 3 (sixth conveying unit 66).

The feeding operation of the yarn feeding bobbin 11 formed in each of the spinning units 32 arranged on the front side of the machine frame of the spinning machine 3 is common to the feeding operation except that the yarn feeding bobbin 11 is fed to the automatic winder 4A on the left side and the used yarn feeding bobbin 11 (empty bobbin 13) is fed to each of the spinning units 32 arranged on the rear side of the machine frame.

The operation and effect of the yarn winding system 1 according to the above embodiment will be described. In the present embodiment, one automatic winder 4 is constituted by one machine control device 41 and a plurality of winding units 42 under the control of the one machine control device 41. In the yarn winding system 1 of the present embodiment, two of the above-described one automatic winder 4 are provided for one spinning frame 3. In the yarn winding system 1 of the present embodiment, the single spinning machine 3 and the two automatic winders 4 and 4 are arranged along the arrangement direction D1 of the spinning unit 32. Thus, two automatic winder 4, 4 can be arranged for one spinning frame 3 without complicating the structure of the transport device 5.

In the yarn winding system 1 according to the above embodiment, since two automatic winders 4, 4 are provided for one spinning frame 3, the manufacturing capability of the package 15 can be improved without requiring a large change in the structure of the conventional automatic winders 4, such as an increase in the output of the blower. In the yarn winding system 1 of the above embodiment having this configuration, since the yarn feeding bobbin 11 is not fed from the single spinning frame 3 to the two automatic winders 4 and 4 so that the yarn feeding bobbin 11 does not pass through the other automatic winder 4, the yarn winding system does not cause a problem that the yarn feeding bobbin 11 is not fed to the winding unit 42 disposed at a position distant from the entrance of the automatic winder 4. In addition, even if one of the two automatic winders 4, 4 is in a state where it is necessary to stop for maintenance or the like, the operation of the yarn winding system 1 can be continued by the other automatic winder 4 and the one spinning frame 3. As described above, in the yarn winding system 1 of the above embodiment, the manufacturing capability of the package 15 can be improved, and the possibility of the operation of the yarn winding system 1 being completely stopped can be reduced.

In the yarn winding system 1 of the above embodiment, since the automatic winder 4 is disposed at both ends of one fine spinning machine 3 in the arrangement direction D1, two automatic winders 4, 4 can be disposed for one fine spinning machine 3 with a simple configuration of the conveying device 5.

In the yarn winding system 1 of the above embodiment, the yarn feeding bobbin 11 is fed from the spinning unit 32 arranged at the rear side of the machine frame of the spinning machine 3 to the right automatic winder 4B, the empty bobbin 13 is fed from the right automatic winder 4B to the spinning unit 32 arranged at the front side of the machine frame of the spinning machine 3, the yarn feeding bobbin 11 is fed from the spinning unit 32 arranged at the front side of the machine frame of the spinning machine 3 to the left automatic winder 4, and the empty bobbin 13 is fed from the right automatic winder 4B to the spinning unit 32 arranged at the rear side of the machine frame of the spinning machine 3. In this configuration, the manufacturing capability of the package 15 can be improved and the possibility of complete stop of the operation of the yarn winding system 1 can be reduced without greatly changing the configuration of the transfer device 5 in the conventional spinning machine 3.

In the structure in which the yarn feeding bobbin 11 formed by the spinning unit 32 arranged at the rear side of the machine frame of the spinning machine 3 is returned not directly as the empty bobbin 13 to the spinning unit 32 arranged at the rear side of the machine frame of the spinning machine 3 but to the spinning unit 32 arranged at the front side of the machine frame of the spinning machine 3 as in the yarn winding system 1 of the above embodiment, a difference is likely to occur in the balance between the supply of the yarn feeding bobbin 11 and the supply of the empty bobbin 13. Accordingly, in the yarn winding system 1 having the conveying device 5 configured to appropriately adjust the balance between the supply of the yarn feeding bobbin 11 and the supply of the empty bobbin 13, the conveying device 5 includes the second conveying section 62 and the fifth conveying section 65 capable of adjusting the timing of supplying the yarn feeding bobbin 11 from the spinning frame 3 to the automatic winder 4 and the timing of supplying the empty bobbin 13 from the automatic winder 4 to the spinning frame 3.

In the above, one embodiment of one aspect of the present disclosure has been described, but one aspect of the present disclosure is not limited to the above embodiment.

Modification 1 >

The yarn winding system 1A according to modification 1 differs from the yarn winding system 1 according to the above-described embodiment in the method of dividing groups among the plurality of spinning units 32 provided in the spinning machine 3 and in the structure of the portion of the transporting device 5 disposed below the spinning machine 3. First, in the yarn winding system 1 of the above embodiment, the groups are different from each other by the group of the spinning units 32 arranged on the front side of the machine and the group of the spinning units 32 arranged on the rear side of the machine, but as shown in fig. 6, in the yarn winding system 1A of modification 1, the groups are different from each other by the group of the spinning units 32 arranged on the right side of the machine (including the spinning units 32 arranged on the front side of the machine and the rear side of the machine) and the group of the spinning units 32 arranged on the left side of the machine (including the spinning units 32 arranged on the front side of the machine and the rear side of the machine). Hereinafter, this group is referred to as a "right group" and a "left group".

In addition, the structure of the conveying device 5 is also changed in accordance with the group. Specifically, instead of the first conveying section 61 arranged below the spinning units 32 arranged on the rear side of the machine frame of the spinning machine 3, a first conveying section 61A formed along the lower side of the group of the spinning units 32 belonging to the right group is arranged, and instead of the sixth conveying section 66 arranged below the spinning units 32 arranged on the front side of the machine frame of the spinning machine 3, a sixth conveying section 66A formed along the lower side of the group of the spinning units 32 belonging to the left group is arranged.

The conveying device 5 forms a first closed-loop conveying path between one automatic winder 4 and the spinning units 32 belonging to the right group (first group), and forms a second closed-loop conveying path between the remaining one automatic winder 4 and the spinning units 32 belonging to the left group (second group). The first closed-loop conveying path is constituted by a first conveying section 61A, a second conveying section 62, a third conveying section 63, a fourth conveying section 64, and a fifth conveying section 65. The second closed-loop conveying path is constituted by a sixth conveying portion 66A, a second conveying portion 62, a third conveying portion 63, a fourth conveying portion 64, and a fifth conveying portion 65.

The first conveying section 61A is formed in a U-shape with a machine outlet and a machine inlet disposed on the right side of the machine as both ends of the conveying section. The first conveying portion 61A can be appropriately constituted by a known structure including the following members or the like as described above: a guide groove formed by the guide plate; a conveyor belt or a round belt arranged below the guide groove along the guide groove; and a driving device for driving the conveyor belt or the round belt. The first conveying unit 61A feeds out the yarn supplying bobbin 11 supplied to the first conveying unit 61A to the right automatic winder 4B in the collective doffing of the spinning unit 32 arranged on the right side of the spinning machine 3. The first conveying unit 61A conveys the empty bobbin 13 supplied from the right automatic winder 4B to the lower side of each spinning unit 32.

The sixth conveying section 66A has a U-shape with a machine outlet and a machine inlet disposed on the left side of the machine as both ends of the conveying section. The sixth conveying portion 66A can be appropriately constituted by a known structure including the following components, for example: a guide groove formed by the guide plate; a conveyor belt or a round belt arranged below the guide groove along the guide groove; and a driving device for driving the conveyor belt or the round belt. The sixth conveying unit 66A feeds out the yarn supplying bobbin 11 supplied to the sixth conveying unit 66A to the automatic winder 4A on the left side in the collective doffing of the spinning unit 32 arranged on the left side of the spinning machine 3. The sixth conveying unit 66A conveys the empty bobbin 13 supplied from the left automatic winder 4A to the lower side of each spinning unit 32.

The second conveying section 62 from which the yarn feeding bobbin 11 is fed out from the first conveying section 61A and the sixth conveying section 66A, and the fifth conveying section 65 from which the empty bobbin 13 is fed into the first conveying section 61A and the sixth conveying section 66A are as described in the above embodiment, and therefore, the detailed description thereof is omitted, including the illustration in fig. 6.

As described above, the spinning machine 3 of modification 1 includes the group of spinning units 32 (spinning units belonging to the first group) arranged on the right side of the machine frame and the group of spinning units 32 (spinning units belonging to the second group) arranged on the left side of the machine frame. In the spinning machine 3 of modification 1, the plurality of spinning units 32 belong to any one of two groups different from each other. The two groups are also groups of the spinning units 32 that perform doffing simultaneously, respectively.

The conveying device 5 conveys the yarn feeding bobbin 11 from the group of spinning units 32 arranged on the right side of the machine frame of the spinning machine 3 to the right-side automatic winder 4B, and conveys the empty bobbin 13 from the right-side automatic winder 4B to the group of spinning units 32 arranged on the right side of the machine frame of the spinning machine 3. The transport device 5 transports the yarn feeding bobbin 11 from the group of spinning units 32 arranged on the left side of the machine frame of the spinning machine 3 to the left automatic winder 4A, and transports the empty bobbin 13 from the left automatic winder 4A to the group of spinning units 32 arranged on the left side of the machine frame of the spinning machine 3.

In the yarn winding system 1A of modification 1, two of the above-described one automatic winder 4 are provided for one spinning frame 3. In the yarn winding system 1A of modification 1 described above, since the single spinning machine 3 and the two automatic winders 4, 4 are arranged along the arrangement direction D1 of the spinning units 32, the two automatic winders 4, 4 can be arranged for the single spinning machine 3 without complicating the structure of the conveying device 5.

In the yarn winding system 1A according to modification 1, since two automatic winders 4, 4 are provided for one spinning frame 3, the productivity of the package 15 can be improved without requiring a large change in the structure of the conventional automatic winders 4, such as an increase in the output of the blower. In the yarn winding system 1A having this configuration, the yarn feeding bobbin 11 is not fed from the single spinning frame 3 to the two automatic winders 4, 4 so that the yarn feeding bobbin 11 is not fed to the other automatic winders 4, and therefore, the yarn feeding bobbin 11 is not fed to the winding unit 42 disposed at a position distant from the entrance of the automatic winder 4. In addition, even if one of the two automatic winders 4, 4 is in a state where it is necessary to stop for maintenance or the like, the operation of the yarn winding system 1A can be continued by the other automatic winder 4 and the one spinning frame 3. As described above, in the yarn winding system 1A according to modification 1, the manufacturing capability of the package 15 can be improved, and the possibility of the yarn winding system 1A being completely stopped can be reduced.

In the yarn winding system 1A of modification 1 described above, since the automatic winder 4 is disposed at both ends of one fine spinning machine 3 in the arrangement direction D1, two automatic winders 4, 4 can be disposed for one fine spinning machine 3 with a simpler configuration of the conveying device 5.

Modification 2 >

In the above embodiment and modification 1, the automatic winder 4, 4 is disposed at each end of the single spinning frame 3 in the arrangement direction D1, but the present invention is not limited thereto. For example, as shown in fig. 7, two (a plurality of) automatic winders 4, 4 may be arranged on the right end side of one spinning frame 3 in the arrangement direction D1. Hereinafter, the automatic winder disposed on the side closer to the spinning frame 3 in the arrangement direction may be referred to as a "first automatic winder 4C", and the automatic winder disposed on the side farther from the spinning frame 3 may be referred to as a "second automatic winder 4D". The yarn winding system 1B according to modification 2 is different from the above-described embodiment or modification 1 in the details.

In the modification 2, the explanation has been given of an example in which two (a plurality of) automatic winders 4, 4 are arranged on the right end side of one spinning frame 3 in the arrangement direction D1, but two (a plurality of) automatic winders 4, 4 may be arranged on the left end side of one spinning frame 3 in the arrangement direction D1.

In the yarn winding system 1B according to modification 2, the structure in which the plurality of spinning units 32 belong to any one of two different groups as in the above-described embodiment and modification 1 is not essential. Therefore, instead of the configuration of the first conveying section 61 (the first conveying section 61A of modification 1) of the above-described embodiment, one first conveying section 61B is disposed in the yarn winding system 1B along the lower portions of all the spinning units 32 arranged on the rear side and the front side of the machine 3.

The conveying device 5 forms a first closed-loop conveying path between the single spinning machine 3, the branching portion 68, the single automatic winder 4C, and the joining portion 69, and forms a second closed-loop conveying path between the single spinning machine 3, the branching portion 68, the remaining single automatic winder 4D, and the joining portion 69. The first closed-loop conveying path and the second closed-loop conveying path are each constituted by a first conveying portion 61B, a second conveying portion 62, a third conveying portion 63, a fourth conveying portion 64, and a fifth conveying portion 65.

The first conveying section 61B is formed in a U-shape with a machine outlet and a machine inlet disposed on the right side of the machine as both ends of the conveying section. The first conveying portion 61B can be appropriately constituted by a known structure including the following members or the like as described above: a guide groove formed by the guide plate; a conveyor belt or a round belt arranged below the guide groove along the guide groove; and a driving device for driving the conveyor belt or the round belt. The first conveying unit 61B feeds the yarn feeding bobbin 11 supplied to the first conveying unit 61B in the collective doffing of all the spinning units 32 of the spinning machine 3 toward the first automatic winder 4C and the second automatic winder 4D. The first conveying unit 61B conveys the empty bobbin 13 supplied from the first automatic winder 4C and the second automatic winder 4D to the lower side of each spinning unit 32.

The conveying device 5 of the yarn winding system 1B of modification 2 is different from the conveying device 5 of the above-described embodiment and modification 1 in the following points: in order to correspond to a configuration in which two automatic winders 4 are arranged at one end side of the spinning frame 3 in the arrangement direction D1, a branching portion 68 for branching the conveyance path and a joining portion 69 for joining the conveyance paths are provided.

The branching portion 68 is provided in the second conveying portion 62. The branching unit 68 is a part for distributing the yarn feeding bobbin 11 to the first automatic winder 4C and the second automatic winder 4D, and is controlled by the machine control device 41. The third conveying unit 63 and the fourth conveying unit 64 are the same as those described in the above embodiment, and therefore, the description thereof is omitted here. The merging portion 69 is provided in the fifth conveying portion 65. The merging portion 69 merges the empty bobbins 13 fed from the first automatic winder 4C and the second automatic winder 4D. The fourth conveying unit 64 and the fifth conveying unit 65 are the same as those described in the above embodiment, and therefore, the description thereof is omitted here.

As described above, the conveying device 5 is connected to the first automatic winder 4C and the second automatic winder 4D from the single spinning frame 3 via the branching portion 68, and is connected to the single spinning frame 3 from the first automatic winder 4C and the second automatic winder 4D via the joining portion 69.

In the yarn winding system 1B according to modification 2, two of the above-described one automatic winder 4 are provided for one spinning frame 3. In the yarn winding system 1B according to the modification 2, since the single spinning machine 3 and the two automatic winders 4 and 4 are arranged along the arrangement direction D1 of the spinning units 32, the two automatic winders 4 and 4 can be arranged for the single spinning machine 3 without complicating the structure of the conveying device 5.

In the yarn winding system 1B according to modification 2, since two automatic winders 4, 4 are provided for one spinning frame 3, the productivity of the package 15 can be improved without requiring a large change in the structure of the conventional automatic winders 4, such as an increase in the output of the blower. In the yarn winding system 1B having this configuration, the yarn feeding bobbin 11 is fed from the single spinning frame 3 to the two automatic winders 4 and 4 so that the yarn feeding bobbin 11 does not pass through the other automatic winders 4, and therefore, the yarn feeding bobbin 11 is not fed to the winding unit 42 disposed at a position distant from the entrance of the automatic winder 4. In addition, even if one of the two automatic winders 4, 4 is in a state where it is necessary to stop for maintenance or the like, the operation of the yarn winding system 1B can be continued by the other automatic winder 4 and the one spinning frame 3. As described above, in the yarn winding system 1B according to modification 2, the manufacturing capability of the package 15 can be improved, and the possibility of the yarn winding system 1B being completely stopped can be reduced.

The conveying device 5 of the yarn winding system 1B according to the modification 2 has the branch portion 68 and the joining portion 69, and even when the two automatic winders 4 are disposed at one end side of the single spinning frame 3, the yarn feeding bobbin 11 can be conveyed from the single spinning frame 3 to the two automatic winders 4 and 4 with a simpler structure without passing the yarn feeding bobbin 11 through the other automatic winders 4.

< other modifications >
