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

  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 it by the CPU. The control device 31 may be composed of a plurality of electronic control units. The control device 31 functions as a generation unit that generates spinning information including information regarding at least one of the processing status of forming the yarn feeding bobbin 11 and the spinning completion conditions of the yarn feeding bobbin 11.

  Information relating to the processing status of the formation of the yarn feeding bobbin 11 (hereinafter referred to as “processing status information”) is, for example, the remaining time until the yarn feeding bobbins 11 are simultaneously doffed in the plurality of spinning units 32 by simultaneous doffing. It is information etc. which show. The control device 31 can obtain the processing status information as described above, for example, by monitoring the operating status of each spinning unit 32 and referring to the settings related to the operation of each spinning unit 32.

  Information relating to the spinning completion conditions of the yarn feeding bobbin 11 (hereinafter referred to as “completion condition information”) relates to, for example, conditions (doffing conditions) that must be satisfied when the yarn feeding bobbin 11 is doffed in each spinning unit 32. Information. The completion condition information is, for example, information related to the yarn winding end state in the yarn supplying bobbin 11. The information on the state of the end of winding of the yarn indicates, for example, whether or not a so-called bunch winding process is performed in the state of the end of winding of the yarn in the yarn supplying bobbin 11, whether or not it is formed on a half-bore bobbin, and the like. Information.

  As an example in the present embodiment, the control device 31 generates, as spinning information, data including the above-described processing status information and completion condition information, and doffing information for specifying the timing at which the yarn feeding bobbin 11 is formed. And transmitted to the automatic winder 4 via the transmission unit 31c. The timing at which the control device 31 generates spinning information and transmits it to the automatic winder 4 is arbitrary, but in the present embodiment, as an example, the control device 31 periodically generates spinning information at a predetermined interval. To the automatic winder 4. As a result, the automatic winder 4 can grasp the processing state of the spinning machine 3 in a timely manner, and the winding speed of the winder unit 42 can be appropriately controlled each time (details will be described later). .

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

  The receiving unit 41 c receives the spinning information transmitted from the spinning machine 3. The reception by the receiving unit 41c may be performed by wire 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 may be employed as the transmission medium. In FIG. 5, the reception unit 41 c is illustrated as a separate element from the control device 41, but the reception unit 41 c may be configured to be included in the control device 41. That is, the receiving unit 41 c may be a communication function built in the control device 41.

  The control device 41 is an electronic control unit having a CPU, a ROM, a RAM, and the like. The control device 41 loads the program stored in the ROM into the RAM and executes it by the CPU, thereby executing various controls. The control device 41 may be composed of 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 41c. Specifically, the control device 41 determines the operation of each winder unit 42 based on the spinning information, and transmits a control signal indicating the determined operation to each winder unit 42 in a timely manner. Control the behavior.

  The control device 41 determines the winding speed when each winder unit 42 winds the yarn from the yarn feeding bobbin 11 based on the processing status information included in the spinning information, and the yarn feeding bobbin at the determined winding speed. 11 controls the operation of each winder unit 42 so as to wind the yarn.

  As described above, the yarn supplying bobbin 11 is transferred from the spinning machine 3 to the automatic winder 4, while the empty bobbin 12 is transferred from the automatic winder 4 to the spinning machine 3. Here, the pace (supply pace) at which the yarn feeding bobbin 11 is transferred from the spinning machine 3 to the automatic winder 4 per unit time, and the empty bobbin 12 is transferred from the automatic winder 4 to the spinning machine 3 per unit time. Slower than the pace (discharge pace) means that the processing of the automatic winder 4 has a margin. That is, it means that the winding speed of each winder unit 42 can be reduced. On the other hand, if the supply pace is faster than the discharge pace, it means that there is no room 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 machine 3 and the automatic winder 4.

  Therefore, the control device 41 calculates the supply pace of the yarn feeding bobbin 11 based on the processing status information included in the spinning information, and the supply pace and the winding process pace in each winder unit 42 (that is, the empty bobbin 12). The winding speed of each winder unit 42 is determined so as to be balanced with the discharge pace). Thus, when the supply pace is faster than the discharge pace, the control device 41 increases the winding speed of each winder unit 42 to balance the processing of the spinning machine 3 and the processing of the automatic winder 4. be able to. When the supply pace is slower than the discharge pace, the control device 41 increases the winding quality (that is, the quality of the package 15) in each winder unit 42 by slowing the winding speed of each winder unit 42. Can be made.

  Further, the control device 41 controls the bobbin preparation operation for the yarn feeding bobbin 11 in the bobbin preparation device 7 provided in the bobbin transfer device 5 based on the information about the yarn winding end included in the spinning information. For example, the control device 41 specifies whether or not the bunch winding process is performed in the yarn feeding bobbin 11 from the information related to the yarn winding end. When it is specified that the bunch winding process is performed on the yarn feeding bobbin 11, the control device 41 does not require an operation when the bunch winding process is performed (for example, the illustration provided in the bobbin preparation device 7). The operation of cutting the yarn end of the yarn feeding bobbin 11 by the yarn end cutting device that does not perform or the operation of sucking the yarn end of the yarn feeding bobbin 11 by the yarn end suction device (not shown) provided in the bobbin preparation device 7 is omitted The operation of the bobbin preparation device 7 is controlled. Thereby, it is possible to prevent the bobbin preparation device 7 from performing a useless operation.

  Further, for example, the control device 41 specifies whether or not the yarn supplying bobbin 11 is formed on a half-bob bobbin from information related to the end of winding of the yarn. When it is determined that the yarn feeding bobbin 11 is formed on a half-bobbin, the control device 41 performs, for example, a search operation (the yarn end of the yarn feeding bobbin 11 is searched for the above-described yarn end cutting device and yarn end suction device). The operation of the bobbin preparation device 7 is controlled so that the operation for searching) is performed in a range corresponding to the half ball bobbin (for example, a predetermined range on the bottom portion 12a side). As a result, it is possible to prevent the search operation from being performed in a useless range and to quickly find the yarn end. As described above, the operation of the bobbin preparation device 7 can be optimized by controlling the bobbin preparation operation in the bobbin preparation device 7 in accordance with the yarn winding end state in the yarn feeding bobbin 11.

  Here, the spinning completion conditions of the yarn feeding bobbin 11 may differ for each timing of simultaneous doffing in the spinning machine 3. For example, at the time of simultaneous duffing at the first timing, the bunch winding process is performed on the yarn supply bobbin 11, and at the time of simultaneous duffing at the second timing after the first timing, the yarn supply bobbin 11 In some cases, spinning completion conditions are set so that the bunch winding process is not performed. The reason that the bunch winding process is not performed in the yarn feeding bobbin 11 during the simultaneous duffing at the second timing is that the roving yarn wound around the roving bobbin set in the spinning machine 3 is a lot of fine spinning. The case where the unit 32 is used up or the case where it is necessary to perform duffing in a halfway state due to a trouble in the spinning machine 3 can be cited. In some cases, the yarn feeding bobbins 11 formed at the first and second timings having different spinning completion conditions are mixed and transferred to the bobbin preparation device 7. In such a case, when the control device 41 performs the preparatory work on the yarn feeding bobbin 11 formed at the first timing, the control device 41 is included in the first spinning information including the duffing information indicating the first timing. It is necessary to control the operation of the bobbin preparation device 7 based on completion condition information (that is, completion condition information applied to the yarn feeding bobbin 11 formed at the first timing). Similarly, when the control device 41 performs the preparatory work on the yarn feeding bobbin 11 formed at the second timing, the completion condition included in the second spinning information including the duffing information indicating the second timing It is necessary to control the operation of the bobbin preparation device 7 based on information (that is, completion condition information applied to the yarn feeding bobbin 11 formed at the second timing). The automatic winder 4 is configured to be able to realize such control. Hereinafter, this mechanism will be described.

  First, the control device 41 periodically receives spinning information from the spinning machine 3 via the receiving unit 41c, thereby obtaining the first spinning information including the duffing information indicating the first timing and the second timing. Second spinning information including the doffing information shown is stored. When the yarn supplying bobbin 11 is supplied to the bobbin preparing device 7, the RF reader 7 a provided in the bobbin preparing device 7 is written on the RF tag 63 provided in the tray 6 for transferring the yarn supplying bobbin 11. The received information is read and transmitted to the control device 41. Thereby, the control device 41 acquires duffing information indicating the timing at which the yarn feeding bobbin 11 supplied to the bobbin preparation device 7 is formed.

  Subsequently, the control device 41 detects the doffing information received from the RF reader 7a from the accumulated spinning information (doffing information indicating the timing at which the yarn feeding bobbin 11 is formed. The spinning information including the doffing information that matches the yarn feeding bobbin 11), and the operation of the bobbin preparation device 7 is controlled based on the spinning information. Specifically, when the duffing information received from the RF reader 7a indicates the first timing (for example, the first doffing), the control device 41 is based on the completion condition information included in the first spinning information. The bobbin preparation device 7 controls the bobbin preparation operation. On the other hand, when the doffing information received from the RF reader 7a indicates the second timing (for example, the second doffing), the control device 41 sets the bobbin preparation device based on the completion condition information included in the second spinning information. 7 to control the bobbin preparation operation.

As a result, the automatic winder 4 makes each winder based on the processing status of forming the yarn feeding bobbin 11 in the spinning machine 3 (for example, the supply timing of the yarn feeding bobbin 11 transferred from the spinning machine 3 to the automatic winder 4). The winding speed of the unit 42 can be appropriately controlled.

  In the yarn winding system 1, the spinning information includes information related to the state of the yarn winding end in the yarn supplying bobbin 11 as information related to the spinning completion condition. Further, the automatic winder 4 has a bobbin preparation device 7 that performs pre-preparation for processing the yarn of the yarn supply bobbin 11 in the bobbin transfer device 5 that transfers the yarn supply bobbin 11 from the spinning machine 3 to the automatic winder 4. ing. The control device 41 controls the bobbin preparation operation for the yarn feeding bobbin 11 in the bobbin preparation device 7 based on the information related to the end of winding of the yarn. As a result, the automatic winder 4 is based on the yarn winding bobbin 11 formed by the spinning machine 3 based on the yarn winding end state (for example, information indicating the presence / absence of the bunch winding process or a half-bob bobbin). 7 can be appropriately controlled.

  In the yarn winding system 1, the spinning information includes doffing information that identifies the timing at which the yarn feeding bobbin 11 is formed. The tray 6 for transferring the yarn feeding bobbin 11 is provided with an RF tag 63 for recording duffing information. Further, the bobbin preparation device 7 reads the doffing information recorded on the RF tag 63 provided on the tray 6 for transferring the yarn supply bobbin 11 when the yarn supply bobbin 11 is supplied to the bobbin preparation device 7. It has a reader 7a. Further, the control device 41 controls the operation of the bobbin preparation device 7 based on the spinning information including the duffing information that matches the doffing information read by the RF reader 7a. For example, the spinning completion conditions of the yarn supplying bobbin 11 are different at each timing when the yarn supplying bobbin 11 is formed, and the yarn supplying bobbins 11 formed at different timings are mixed and transferred to the bobbin preparation device 7. There is a case. According to the above configuration, even in such a case, it is possible to appropriately control the operation of the bobbin preparation device 7 based on the spinning completion conditions applied to the yarn feeding bobbin 11 to be processed.
