Disclosure of Invention

In the yarn winding system as described above, it is desirable to optimize the operation control of the automatic winder in order to improve the production efficiency and the work quality. As such optimization of the operation control, it is conceivable to appropriately switch the processing speed of the automatic winder according to the processing status of the spinning machine as the preceding machine of the automatic winder, or to appropriately operate the automatic winder according to the spinning completion condition in the spinning machine, for example.

Accordingly, various aspects of the present invention are directed to provide a yarn winding system, a spinning frame, an automatic winder, and a yarn winding method that can optimize operation control of the automatic winder.

A yarn winding system according to an aspect of the present invention is a yarn winding system including a spinning machine that forms a yarn supplying bobbin and an automatic winder that winds a yarn from the yarn supplying bobbin to form a package. The spinning machine is provided with: a generation unit that generates spinning information including information relating to at least one of a processing status of formation of a yarn supply bobbin and a spinning completion condition of the yarn supply bobbin; and a transmission unit that transmits the spinning information generated by the generation unit to the automatic winder. An automatic winder is provided with: a receiving unit that receives spinning information; and a control unit that controls the operation of the automatic winder based on the spinning information received by the receiving unit.

In this yarn winding system, spinning information including information on at least one of a process status of formation of a yarn supplying bobbin and a spinning completion condition of the yarn supplying bobbin is transmitted from the spinning machine to the automatic winder. The automatic winder controls the operation of the automatic winder based on the spinning information received from the spinning frame. By performing the operation control of the automatic winder based on the spinning information received from the spinning frame in this manner, the operation control of the automatic winder can be optimized.

The spinning information may include information on a process status of formation of the yarn supplying bobbin, and the control unit may determine a winding speed at which the automatic winder winds the yarn from the yarn supplying bobbin based on the information on the process status of formation of the yarn supplying bobbin, and may control the operation of the automatic winder so that the yarn is wound from the yarn supplying bobbin at the determined winding speed. According to this configuration, the automatic winder can appropriately control the winding speed of the automatic winder based on the processing status of formation of the yarn supplying bobbin in the spinning machine (for example, the supply timing of the yarn supplying bobbin transferred from the spinning machine to the automatic winder).

The yarn information may include information on a state of winding completion of the yarn on the yarn supplying bobbin as information on a condition of completion of the spinning, the automatic winder may include a bobbin preparation unit that performs preliminary preparation for processing the yarn on the yarn supplying bobbin, in a bobbin transfer unit that transfers the yarn supplying bobbin from the spinning machine to the automatic winder, and the control unit may control the preparation operation of the bobbin for the yarn supplying bobbin in the bobbin preparation unit based on the information on the winding completion of the yarn. According to this configuration, the automatic winder can appropriately control the preparation operation of the bobbin in the bobbin preparation section based on the state of the end of winding of the yarn in the yarn supplying bobbin formed by the spinning frame (for example, information indicating the presence or absence of a package yarn winding process and whether the yarn is a half-winding bobbin (japanese: half jade ボビン)).

The yarn supplying bobbin preparing section may include a reading section for reading the timing information recorded in the recording section provided in the tray for transporting the yarn supplying bobbin when the yarn supplying bobbin is supplied to the bobbin preparing section, and the control section may control the operation of the bobbin preparing section based on the yarn information including the timing information matching the timing information read by the reading section. For example, the spinning conditions of the yarn supplying bobbin may differ for each timing of forming the yarn supplying bobbin, and the yarn supplying bobbins formed at different timings may be mixed and transferred to the bobbin preparing section. According to the above configuration, even in such a case, the operation of the bobbin preparation section can be appropriately controlled based on the spinning completion condition applied to the yarn supplying bobbin to be processed.

A spinning machine according to an aspect of the present invention is a spinning machine for forming a yarn supplying bobbin, including: a generation unit that generates spinning information including information relating to at least one of a processing status of formation of a yarn supply bobbin and a spinning completion condition of the yarn supply bobbin; and a transmission unit that transmits the spinning information generated by the generation unit to an automatic winder that winds the yarn from the yarn supplying bobbin to form a package.

In the above-described spinning machine, by transmitting the spinning information to the automatic winder, the automatic winder can grasp information relating to at least one of a processing status of formation of the yarn supplying bobbin and a spinning completion condition of the yarn supplying bobbin. Thus, the automatic winder can optimize the operation control of the automatic winder based on the spinning information.

An automatic winder according to an aspect of the present invention is an automatic winder for winding a yarn from a yarn supplying bobbin to form a package, including: a receiving unit that receives, from a spinning machine that forms a yarn supplying bobbin, spinning information including information on at least one of a processing status of formation of the yarn supplying bobbin and a spinning completion condition of the yarn supplying bobbin; and a control unit that controls the operation of the automatic winder based on the spinning information received by the receiving unit.

In the above automatic winder, the operation of the automatic winder is controlled based on the spinning information received from the fine spinning machine, so that the operation control of the automatic winder can be optimized.

A yarn winding method according to an aspect of the present invention is a yarn winding method performed by a spinning machine that forms a yarn supplying bobbin and an automatic winder that winds a yarn from the yarn supplying bobbin to form a package, and includes the steps of: a generation step of generating, in the spinning machine, spinning information including information on at least one of a processing status of formation of a yarn supplying bobbin and a spinning completion condition of the yarn supplying bobbin; a transmission step of transmitting the spinning information generated in the generation step to an automatic winder; a receiving step of receiving spinning information in an automatic winder; and a control step of controlling, in the automatic winder, an operation of the automatic winder based on the spinning information received in the receiving step.

In this yarn winding method, first, spinning information including information on at least one of a processing status of formation of a yarn supplying bobbin and a spinning completion condition of the yarn supplying bobbin is transmitted from the spinning machine to the automatic winder. Next, in the automatic winder, the operation of the automatic winder is controlled based on the spinning information received from the fine spinning machine. By performing the operation control of the automatic winder based on the spinning information received from the spinning frame in this manner, the operation control of the automatic winder can be optimized.

Detailed Description

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and redundant description thereof is omitted.

As shown in fig. 1, a yarn winding system 1 includes a roving frame 2, a spinning frame 3, and an automatic winder 4. The roving machine 2 generates a roving from the sliver and winds the roving to form a roving bobbin. The spinning machine 3 produces a yarn from the roving and winds the yarn to form a yarn supplying bobbin 11. The automatic winder 4 winds a yarn from the yarn supplying bobbin 11 to form a package. The automatic winder 4 includes a bobbin transfer device (bobbin transfer section) 5. The bobbin transfer device 5 transfers a yarn supplying bobbin 11 from the spinning machine 3 to the automatic winder 4, and transfers an empty bobbin 12 (a bobbin on which a yarn is not wound) from the automatic winder 4 to the spinning machine 3. The bobbin transfer device 5 is provided with a bobbin preparation device (bobbin preparation unit) 7, a remaining yarn processing device, and the like. The bobbin preparation device 7 performs preliminary preparation for the automatic winder 4 to process the yarn of the yarn supplying bobbin 11. When a yarn remains on a bobbin 12 discharged from a yarn supplying bobbin 11, the excess yarn processing device removes the yarn to form an empty bobbin 12. Therefore, the bobbin transfer device 5 has a complicated conveyance path with many curves.

The yarn supplying bobbin 11 and the empty bobbin 12 are respectively transferred in a state of being mounted on the tray 6. As shown in fig. 2, the tray 6 has: a disk-shaped base portion 61; a pin 62 protruding upward from the base portion 61; and an RF (Radio Frequency) tag 63 built in the base part 61. The yarn supplying bobbin 11 and the empty bobbin 12 are respectively placed on the tray 6 with the top 12b of the bobbin 12 facing upward by inserting the pin 62 into the bottom 12a of the bobbin 12. The RF tag (recording portion) 63 stores information on the yarn supplying bobbin 11 mounted on the tray 6. In the yarn winding system 1, the condition of the yarn supplying bobbin 11 mounted on the tray 6 is managed by an RFID (Radio Frequency Identification) technology.

As shown in fig. 1, the roving frame 2 includes a control device 21 for controlling the operation of the roving frame 2 and a plurality of roving units 22 for forming roving bobbins. The control device 21 includes a display unit 21a such as a display and an operation unit 21b such as an input key. The display unit 21a displays the operating conditions of the respective roving units 22. The operation unit 21b is a part for an operator to set the operation conditions of the respective roving units 22.

The spinning machine 3 includes a control device 31 for controlling the operation of the spinning machine 3, and a plurality of spinning units 32 for forming yarn supplying bobbins 11. The control device 31 includes a display unit 31a such as a display and an operation unit 31b such as an input key. The display unit 31a displays the operating state of each spinning unit 32. The operation unit 31b is a part for an operator to set the operation conditions of the respective spinning units 32.

As shown in fig. 3, the spinning unit 32 has a drafting device 33 and a twisting device 34.

The draft device 33 includes a back roller pair 33a, a middle roller pair 33b, and a front roller pair 33 c. The back roller pair 33a, the middle roller pair 33b, and the front roller pair 33c are each composed of a bottom roller and a top roller. A tangential belt is stretched over each roller constituting the middle roller pair 33 b. In the draft device 33, the rear roller pair 33a, the middle roller pair 33b, and the front roller pair 33c rotate at a predetermined speed ratio, and thereby the roving yarn 13 unwound from the roving bobbin is drafted.

The twisting device 34 has a spindle 35, a ring plate 36, a ring 37, and a traveler 38. The spindle 35 rotates the bobbin 12 while holding the bottom 12a of the bobbin 12 with the top 12b of the bobbin 12 facing upward. The ring plate 36 is movable in the axial direction of the bobbin 12. The ring 37 is fixed to the ring plate 36. The traveler 38 is supported by the ring 37 and is movable along the ring 37.

In the twisting device 34, the roving yarn 13 drafted in the draft device 33 is inserted into a gap between the ring 37 and the traveler 38, and an end of the roving yarn 13 is fixed to the bobbin 12. In this state, when the bobbin 12 is rotated by the spindle 35, the traveler 38 moves along the ring 37 so as to be pulled by the roving yarn 13. At this time, the ring plate 36 gradually moves from the bottom portion 12a side to the top portion 12b side while reciprocating within a predetermined range along the axial direction of the bobbin 12. In the twisting device 34, the rotation of the traveler 38 is slower than the rotation of the bobbin 12, whereby the roving 13 is twisted to produce the yarn 14, and the yarn 14 is wound around the bobbin 12 to form the yarn supplying bobbin 11.

The spinning machine 3 having the plurality of spinning units 32 configured as described above is configured as a so-called simultaneous doffing type. That is, the spinning machine 3 stores a plurality of empty bobbins 12 transferred from the automatic winder 4 by the bobbin transfer device 5 in advance, and places the empty bobbins 12 in the respective spinning units 32 at once to start the winding of the yarn at once. When the yarn winding is completed in each of the spinning units 32 to form the yarn supplying bobbins 11, the spinning machine 3 drops (doffing) all the yarn supplying bobbins 11 at once. The spinning machine 3 pulls out the empty bobbins 12 stored during this time from the tray 6 and places them on the respective spinning units 32 at once again, and instead, places the yarn supplying bobbins 11 after doffing on the tray 6 at once.

As shown in fig. 1, the automatic winder 4 includes a controller 41 that controls the operation of the automatic winder 4, a plurality of winder units 42 that form a package, and a bobbin transfer device 5. The control device 41 includes a display unit 41a such as a display and an operation unit 41b such as an input key. The display unit 41a displays the operation status of each winder unit 42. The operation portion 41b is a portion for an operator to set the operation conditions of each winder unit 42. The controller 41 also controls the operation of the bobbin transfer device 5.

As shown in fig. 4, the winder unit 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, and a yarn splicing device 48.

The winding device 43 has a cradle 43a and a winding drum 43 b. The cradle 43a supports the package 15. The winding drum 43b rotates the package 15 while traversing the yarn 14. Thereby, the yarn 14 is wound from the yarn supplying bobbin 11 set at a predetermined position to form a package 15. The tension applying device 44 applies a predetermined tension to the yarn 14 travelling from the yarn supplying bobbin 11 to the package 15.

The yarn monitoring device 45 monitors the traveling yarn 14 in order to detect yarn defects (thickness abnormality of the yarn 14, mixing of foreign matter into the yarn 14, and the like). When a yarn defect is detected, the yarn 14 is cut by a cutter provided separately. When the yarn 14 is cut, the upper yarn catching device 46 catches the yarn end of the yarn 14 on the package 15 side and guides the yarn end to the yarn joining device 48. When the yarn 14 is cut, the lower yarn catching device 47 catches the yarn end of the yarn 14 on the yarn supplying 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.

As shown in fig. 1, the bobbin transfer device 5 includes an RF writer 51. When the yarn supplying bobbin 11 is transferred from the spinning machine 3 to the automatic winder 4, the RF writer 51 writes information on the yarn supplying bobbin 11 to the RF tag 63 of the tray 6 on which the yarn supplying bobbin 11 is mounted. The information on the yarn supplying bobbin 11 includes unit identification information for identifying the spinning unit 32 forming the yarn supplying bobbin 11 and doffing information (timing information) for identifying timing (timing) of the simultaneous doffing. More specifically, the doffing information is information indicating the timing of performing doffing, such as the time when the simultaneous doffing is performed or the total number of times of doffing from the time point set as the reference. Further, an RF writer 51 may be provided at an outlet in the transfer direction of the yarn supplying bobbin 11 of the spinning machine 3. Further, the RF writer 51 may be provided for each spinning unit 32.

When the yarn supplying bobbin 11 is mounted on the winder unit 42 of the automatic winder 4, the information written in the RF tag 63 by the RF writer 51 is read by the RF reader (reader) 49 provided in each winder unit 42 and transmitted to the controller 41 of the automatic winder 4. Thus, the control device 41 can determine the timing of the simultaneous doffing and the spinning unit 32 forming the yarn supplying bobbin 11 with respect to the yarn supplying bobbin 11 mounted on the winder unit 42.

Next, a configuration in which the spinning information (details will be described later) is transmitted from the spinning machine 3 to the automatic winder 4, and the automatic winder 4 controls the operation of the automatic winder 4 (that is, the operation of each winder unit 42 and the bobbin preparation device 7) based on the spinning information will be described with reference to fig. 5 and 6.

As shown in fig. 5, the spinning machine 3 includes a control device (generation unit) 31 and a transmission unit 31c as functional elements for realizing the above configuration. The automatic winder 4 includes a control device (control unit) 41, a receiving unit 41c, each winder unit 42, and the bobbin transfer device 5. The bobbin transfer device 5 is provided with a bobbin preparation device 7. The bobbin preparation device 7 is provided with an RF reader 7 a.

The control device 31 is an electronic control Unit having a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The control device 31 executes various controls by loading a program stored in the ROM into the RAM and executing the program by the CPU. The control device 31 may be constituted by a plurality of electronic control units. The control device 31 functions as a generation unit that generates spinning information including information on at least one of a processing status of formation of the yarn supplying bobbin 11 and a spinning completion condition of the yarn supplying bobbin 11.

The information on the processing status of the formation of the yarn supplying bobbin 11 (hereinafter referred to as "processing status information") is, for example, information indicating the remaining time until the yarn supplying bobbin 11 is doffed all at once in the plurality of spinning units 32 by the simultaneous doffing. The control device 31 can obtain the above-described process status information by, for example, monitoring the operating status of each spinning unit 32, or referring to settings related to the operation of each spinning unit 32.

The information on the spinning completion condition of the yarn supplying bobbin 11 (hereinafter referred to as "completion condition information") is, for example, information on a condition (doffing condition) to be satisfied when the yarn supplying bobbin 11 is doffed in each of the spinning units 32. The completion condition information is, for example, information related to a state in which the yarn winding on the yarn supplying bobbin 11 is completed. The information on the state of the yarn winding end is, for example, information indicating whether or not a so-called package yarn winding process is performed in the state where the yarn winding on the yarn supplying bobbin 11 is completed, information indicating whether or not the yarn winding is formed into a half-winding bobbin, or the like.

In the present embodiment, as an example, the control device 31 generates data including the above-described processing status information and completion condition information and doffing information for specifying the timing at which the yarn supplying bobbin 11 is formed as spinning information, and transmits the spinning information to the automatic winder 4 via the transmission unit 31 c. The timing at which the control device 31 generates the spinning information and transmits the spinning information to the automatic winder 4 can be set arbitrarily. In the present embodiment, the control device 31 periodically generates spinning information at predetermined intervals, and transmits the spinning information to the automatic winder 4, as an example. Thus, the automatic winder 4 can grasp the processing state of the spinning frame 3 in a timely manner, and can appropriately control the winding speed of the winder unit 42 every time (details will be described later).

The transmission unit 31c transmits the spinning information generated by the control device 31 to the automatic winder 4. The transmission by the transmitter 31c may be performed by a wired method such as a cable or may be performed wirelessly. When the transmission by the transmitter 31c is performed wirelessly, radio waves, infrared rays, or light can be used as a transmission medium. In fig. 5, the transmission unit 31c is illustrated as an element separate from the control device 31, but the transmission unit 31c may be included in the control device 31. That is, the transmission unit 31c may be a communication function incorporated in the control device 31.

The receiving unit 41c receives the spinning information transmitted from the spinning machine 3. The reception by the receiver 41c may be performed by a wired system such as a cable or may be performed wirelessly. When the reception by the receiving unit 41c is performed wirelessly, radio waves, infrared rays, or light can be used as a transmission medium. In fig. 5, the receiving unit 41c is illustrated as an element separate from the control device 41, but the receiving unit 41c may be included in the control device 41. That is, the receiving unit 41c may be a communication function incorporated in the control device 41.

The control device 41 is an electronic control unit having a CPU, ROM, RAM, and the like. The control device 41 executes various controls by loading a program stored in the ROM into the RAM and executing it by the CPU. The control device 41 may be constituted by a plurality of electronic control units. The control device 41 controls the operation of the automatic winder 4 based on the spinning information received by the receiving unit 41 c. Specifically, the control device 41 determines the operation of each winder unit 42 based on the spinning information, and controls the operation of each winder unit 42 by transmitting a control signal indicating the determined operation to each winder unit 42 at appropriate timing.

The control device 41 determines a winding speed at which each winder unit 42 winds the yarn from the yarn supplying bobbin 11 based on the processing state information included in the spinning information, and controls the operation of each winder unit 42 so that the yarn is wound from the yarn supplying bobbin 11 at the determined winding speed.

As described above, the yarn supplying bobbin 11 is transferred from the spinning machine 3 to the automatic winder 4, and the empty bobbin 12 is transferred from the automatic winder 4 to the spinning machine 3. Here, the fact that the pace (supply pace) at which the yarn-supplying bobbin 11 is transferred from the spinning machine 3 to the automatic winder 4 per unit time is slower than the pace (discharge pace) at which the empty bobbin 12 is transferred from the automatic winder 4 to the spinning machine 3 per unit time means that there is a margin in the processing of the automatic winder 4. That is, this means that the winding speed of each winder unit 42 can be reduced. On the other hand, the supply pace being faster than the discharge pace means that there is no margin in the processing of the automatic winder 4. That is, it means that the winding speed of each winder unit 42 needs to be increased in order to balance the processing speed of the spinning frame 3 and the processing speed of the automatic winder 4.

Therefore, the control device 41 calculates the supply step of the yarn supplying bobbin 11 based on the processing state information included in the spinning information, and determines the winding speed of each winder unit 42 so as to balance the supply step with the step of the winding process in each winder unit 42 (that is, the discharge step of the empty bobbin 12). Thus, when the supply step is faster than the discharge step, the control device 41 can balance the process of the spinning machine 3 and the process of the automatic winder 4 by increasing the winding speed of each winder unit 42. In addition, when the supply step is slower than the discharge step, the control device 41 can improve the winding quality in each winder unit 42 (that is, the quality of the package 15) by slowing down the winding speed of each winder unit 42.

Further, the control device 41 controls the preparation operation of the bobbin for the yarn supplying bobbin 11 in the bobbin preparation device 7 provided in the bobbin transfer device 5 based on the information on the end of winding the yarn included in the spinning information. For example, the control device 41 determines whether or not the yarn supplying bobbin 11 is subjected to the package yarn winding process based on the information on the end of winding the yarn. When it is determined that the bunch winding process is performed on the yarn supplying bobbin 11, the control device 41 controls the operation of the bobbin preparing device 7 so as to omit an operation (for example, an operation of cutting the yarn end of the yarn supplying bobbin 11 by a yarn end cutting device (not shown) provided in the bobbin preparing device 7 and an operation of sucking the yarn end of the yarn supplying bobbin 11 by a yarn end sucking device (not shown) provided in the bobbin preparing device 7) which is unnecessary when the bunch winding process is performed. This prevents the bobbin preparation device 7 from performing an unnecessary operation.

Further, for example, the controller 41 determines whether or not the yarn supplying bobbin 11 is formed as a half bobbin based on information on the end of winding the yarn. When it is determined that the yarn supplying bobbin 11 is formed as a half bobbin, the controller 41 controls the operation of the bobbin preparing device 7 so that, for example, the seek operation of the yarn end cutting device and the yarn end suction device (the operation for seeking the yarn end of the yarn supplying bobbin 11) described above is performed within a range (for example, a predetermined range on the bottom portion 12a side) corresponding to the half bobbin. This prevents the seek operation from being performed in an unnecessary range, and enables yarn ends to be quickly found. By controlling the preparatory operation of the bobbin in the bobbin preparation device 7 in accordance with the state of the yarn winding end in the yarn supplying bobbin 11 as described above, the operation of the bobbin preparation device 7 can be optimized.

Here, the spinning completion condition of the yarn supplying bobbin 11 may be different for each timing of the simultaneous doffing in the spinning machine 3. For example, the spinning completion condition may be set so that the yarn winding process is performed on the yarn supplying bobbin 11 at the 1 st timing for the simultaneous doffing and the yarn winding process is not performed on the yarn supplying bobbin 11 at the 2 nd timing after the 1 st timing for the simultaneous doffing. The reason why the package yarn winding process is not performed in the yarn supplying bobbin 11 in the simultaneous doffing at the 2 nd timing includes a case where the roving wound on the roving bobbin placed on the spinning machine 3 is used up by a large number of spinning units 32, a case where the doffing has to be performed in an incomplete state due to a trouble of the spinning machine 3, and the like. Then, the yarn supplying bobbins 11 formed at the 1 st timing and the 2 nd timing different from each other in the spinning completion condition are sometimes mixed and transferred to the bobbin preparing device 7. In such a case, when performing a preparation operation for the yarn supplying bobbin 11 formed at the 1 st timing, the control device 41 needs to control the operation of the bobbin preparation device 7 based on the finish condition information included in the 1 st spinning information including the doffing information indicating the 1 st timing (that is, the finish condition information applied to the yarn supplying bobbin 11 formed at the 1 st timing). Similarly, when preparing the yarn supplying bobbin 11 formed at the 2 nd timing, the control device 41 needs to control the operation of the bobbin preparing device 7 based on the finish condition information included in the 2 nd spinning information including the doffing information indicating the 2 nd timing (that is, the finish condition information applied to the yarn supplying bobbin 11 formed at the 2 nd timing). The automatic winder 4 is configured to be able to realize such control. The structure will be described below.

First, the control device 41 periodically receives the spinning information from the spinning machine 3 via the receiving unit 41c, and accumulates the 1 st spinning information including the doffing information indicating the 1 st timing and the 2 nd spinning information including the doffing information indicating the 2 nd timing. When the yarn supplying bobbin 11 is supplied to the bobbin preparing device 7, the RF reader 7a provided in the bobbin preparing device 7 reads information written in the RF tag 63 provided on the tray 6 for transporting the yarn supplying bobbin 11, and transmits the information to the control device 41. Thereby, the control device 41 acquires doffing information indicating a timing of forming the yarn supplying bobbin 11 supplied to the bobbin preparing device 7.

Next, the control device 41 extracts, from among the accumulated spinning information, spinning information including doffing information that matches the doffing information (doffing information indicating the timing of forming the yarn supplying bobbin 11. for example, information specifying the yarn supplying bobbin 11 that has been doffed with the next doffing) received from the RF reader 7a, and controls the operation of the bobbin preparing device 7 based on the spinning information. Specifically, when the doffing information received from the RF reader 7a indicates the 1 st timing (for example, the 1 st doffing), the control device 41 controls the preparation operation of the bobbin by the bobbin preparation device 7 based on the completion condition information included in the 1 st spinning information. On the other hand, when the doffing information received from the RF reader 7a indicates the 2 nd timing (for example, the 2 nd doffing), the control device 41 controls the preparation operation of the bobbin by the bobbin preparation device 7 based on the completion condition information included in the 2 nd spinning information. Thus, the preparation operation of the bobbin by the bobbin preparation device 7 can be appropriately controlled based on the spinning completion condition (for example, information on the end of winding of the yarn such as whether the package yarn winding process is performed or whether the yarn is formed into a half-winding bobbin) applied to the yarn supplying bobbin 11 supplied to the bobbin preparation device 7.

Next, the operation of the yarn winding system 1 (including the operation of the yarn winding method according to the present embodiment) will be described with reference to fig. 6. As shown in fig. 6, first, the control device 31 of the spinning machine 3 generates spinning information including at least one of processing status information and completion condition information (step S1, generation step). Next, the transmission unit 31c of the spinning machine 3 transmits the spinning information generated in step S1 to the automatic winder 4 (step S2, transmission step).

Next, the receiving unit 41c of the automatic winder 4 receives the spinning information (step S3, receiving step). The spinning information received by the receiving unit 41c is delivered to the control device 41. The control device 41 controls the winding speed of each winder unit 42 based on the processing status information included in the spinning information (step S4, control step). Specifically, the control device 41 calculates the supply step of the yarn supplying bobbin 11 based on the processing state information included in the spinning information, and determines the winding speed of each winder unit 42 so that the supply step is balanced with the step of the winding process in each winder unit 42 (that is, the discharge step of the empty bobbin 12). The controller 41 controls the operation of each winder unit 42 so that the yarn is wound from the yarn supplying bobbin 11 at the determined winding speed.

When the yarn supplying bobbin 11 is supplied to the bobbin preparing device 7, the RF reader 7a provided in the bobbin preparing device 7 reads the doffing information written in the RF tag 63 provided in the tray 6 for transporting the yarn supplying bobbin 11, and transmits the information to the control device 41 (step S5). Next, the control device 41 controls the preparation operation of the bobbin by the bobbin preparation device 7 based on the spinning information including the doffing information matching the doffing information received from the RF reader 7a (step S6, control step). Specifically, as described above, the control device 41 controls the operation of the bobbin preparing device 7 based on information on the end of winding of the yarn on the yarn supplying bobbin 11, which is included in the spinning information, for example.

As described above, in the yarn winding system 1, the spinning information including information on at least one of the processing status of formation of the yarn supplying bobbin 11 and the spinning completion condition of the yarn supplying bobbin 11 is transmitted from the spinning machine 3 to the automatic winder 4. Then, the control device 41 of the automatic winder 4 controls the operation of the automatic winder 4 (that is, the operation of each winder unit 42, the operation of the bobbin preparation device 7, and the like) based on the spinning information received from the spinning frame 3. By thus performing the operation control of the automatic winder 4 based on the spinning information received from the fine spinning machine 3, the operation control of the automatic winder 4 can be optimized.

In the yarn winding system 1, the spinning information includes information related to a process status of formation of the yarn supplying bobbin 11. Further, the control device 41 determines a winding speed at which each winder unit 42 winds the yarn from the yarn supplying bobbin 11 based on the information on the processing status of the formation of the yarn supplying bobbin 11, and controls the operation of each winder unit 42 so that the yarn is wound from the yarn supplying bobbin 11 at the determined winding speed. Thus, the automatic winder 4 can appropriately control the winding speed of each winder unit 42 based on the processing status of formation of the yarn supplying bobbin 11 in the spinning machine 3 (for example, the supply timing of the yarn supplying bobbin 11 transferred from the spinning machine 3 to the automatic winder 4).

In the yarn winding system 1, the spinning information includes information on the state of the yarn winding end on the yarn supplying bobbin 11 as information on the spinning completion condition. The automatic winder 4 further includes a bobbin preparation device 7 in the bobbin transfer device 5 that transfers the yarn supplying bobbin 11 from the spinning frame 3 to the automatic winder 4, and the bobbin preparation device 7 performs preparation for performing processing on the yarn of the yarn supplying bobbin 11. The controller 41 controls the bobbin preparation operation for the yarn supplying bobbin 11 in the bobbin preparation device 7 based on the information on the end of winding of the yarn. Thus, the automatic winder 4 can appropriately control the yarn preparing operation in the yarn bobbin preparing device 7 based on the state of the end of winding of the yarn in the yarn supplying bobbin 11 formed by the spinning machine 3 (for example, information indicating the presence or absence of a package yarn winding process and whether the yarn is a half-winding bobbin or the like).

In the yarn winding system 1, the spinning information includes doffing information for specifying a timing of forming the yarn supplying bobbin 11. Further, an RF tag 63 for recording doffing information is provided on the tray 6 for transporting the yarn supplying bobbin 11. The bobbin preparation device 7 includes an RF reader 7 a. When the yarn supplying bobbin 11 is supplied to the bobbin preparing device 7, the RF reader 7a reads the doffing information recorded in the RF tag 63 provided on the tray 6 that transports the yarn supplying bobbin 11. Further, the control device 41 controls the operation of the bobbin preparation device 7 based on the spinning information including the doffing information matching the doffing information read by the RF reader 7 a. For example, the conditions for completing the spinning of the yarn supplying bobbin 11 may be different for each timing of forming the yarn supplying bobbin 11, and the yarn supplying bobbins 11 formed at different timings may be mixed and transferred to the bobbin preparing device 7. According to the above configuration, even in such a case, the operation of the bobbin preparation device 7 can be appropriately controlled based on the spinning completion condition applied to the yarn supplying bobbin 11 to be processed.

When the respective attention is paid to the spinning machine 3 and the automatic winder 4, the spinning machine 3 and the automatic winder 4 have the following effects. That is, in the spinning machine 3, by transmitting the spinning information to the automatic winder 4, the automatic winder 4 can grasp information relating to at least one of a processing status of formation of the yarn supplying bobbin 11 and a spinning completion condition of the yarn supplying bobbin 11. This makes it possible to optimize the operation control of the winder unit 42 based on the spinning information in the automatic winder 4. In the automatic winder 4, the operation of the automatic winder 4 is controlled based on the spinning information received from the fine spinner 3, so that the operation control of the automatic winder 4 can be optimized.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, the transmission of the spinning information from the spinning machine 3 to the automatic winder 4 may be performed directly between the spinning machine 3 and the automatic winder 4, or may be performed via a predetermined relay device, for example. In the above-described embodiment, the example in which the operation (winding speed) of each winder unit 42 is controlled based on the processing status information has been described, but the controller 41 may control the operation of the bobbin preparation device 7 based on the processing status information. Similarly, in the above-described embodiment, the example of controlling the preparation operation of the bobbin preparation device 7 based on the completion condition information has been described, but the control device 41 may control the operation of each winder unit 42 based on the completion condition information.
