  • the RF reader 7a arranged on the bobbin preparing device 7 reads the doffing information written on the RF tag 63 provided on the tray 6 transferring the yarn supplying bobbin 11, and transmits the doffing information to the control device 41 (step S5). Then, the control device 41 controls the preparatory operation of the bobbin by the bobbin preparing device 7 based on the spinning information including the doffing information that coincides with the doffing information received from the RF reader 7a (step S6, controlling step). Specifically, as described above, the control device 41 controls the operation of the bobbin preparing device 7 based on, for example, the information relating to the winding end of the yarn of the yarn supplying bobbin 11 included in the spinning information.
  • the automatic winder 4 of the second embodiment further includes an input section 100 and a notifying section 101.
  • the receiving section 41c of the automatic winder 4 cannot receive the spinning information from the spinning machine 3
  • the operator can input the spinning information to the input section 100.
  • the configuration in which the receiving section 41c of the automatic winder 4 cannot receive the spinning information from the spinning machine 3 includes, for example, a case in which the spinning machine 3 does not include the transmitting section 31c for communicating with the automatic winder 4, a case in which the spinning machine 3 includes the transmitting section 31c but the communication function does not operate due to malfunction, and the like.
  • the operator can input a doffing number (number of yarn supplying bobbins 11 which can be supplied by the spinning machine 3 in one doffing), and the doffing information (time point of next doffing, or time required for one doffing) to the input section 10 as the spinning information (step S7).
  • a doffing number number of yarn supplying bobbins 11 which can be supplied by the spinning machine 3 in one doffing
  • the doffing information time point of next doffing, or time required for one doffing
  • the control device 41 of the automatic winder 4 calculates number of yarn supplying bobbins to be wound by the time point of the next doffing (target winding number) from the input information (step S8).
  • the target winding number can be easily calculated by subtracting, from the doffing number, the number of yarn supplying bobbins 11, in which the winding process is completed on the bobbin supplied by the previous doffing.
  • the control device 41 then obtains the time required for the winding unit 42 to wind one yarn supplying bobbin 11 (yarn supplying bobbin processing time) from the winding information (step S9).
  • the yarn supplying bobbin processing time can be obtained by counting the number of winding processed bobbins returned from the automatic winder 4 to the spinning machine at a predetermined time interval. Furthermore, the yarn supplying bobbin processing time can also be obtained by counting the actual time required by the winding unit 42 to process the yarn supplying bobbin.
  • the control device 41 computes a time required to process the yarn supplying bobbin 11 of the target winding number (step S10). The control device 41 then calculates a time point at which the winding of the target winding number is finished (step S11), and compares it with the time point of the next doffing (step S12).
  • step S14 when the time point at which the winding of the target winding number is finished is later than the time point of the next doffing (step S14), the control device 41 increases the winding speed of the winding unit 42 (step S15). Furthermore, when the time point at which the winding of the target winding number is finished is considerably earlier than the time point of the next doffing (step S17), the control device reduces the winding speed of the winding unit 42 (step S18). Furthermore, when the time point at which the winding of the target winding number is finished is substantially the same time point as the time point of the next doffing (step S16), the control device does not change the winding speed of the winding unit 42.
  • the optimization of the operation control of the automatic winder 4 can be realized by controlling the operation of the automatic winder 4 based on the spinning information input by the operator.
  • “considerably early” means early by more than or equal to a predetermined time set as a threshold value.
  • “Substantially the same time point” means early within the predetermined time.
  • the time point referred to herein includes the concept such as “time”, “the moment after predetermined time from the current time”, and the like.
  • a restriction for preventing the winding state of the package 15 from greatly changing by the rapid speed change is preferably provided. For example, since the change in the winding state of the package 15 can be avoided by restricting the change in the winding speed to within ⁇ 10%, the quality of the package will not be downgraded.
  • the fluctuation restriction can be freely changed by the input section 100.
  • the control device 41 can be configured so as not to automatically change the speed when the time point at which the winding of the target winding number is finished is later than the time point of the next doffing or when the time point at which the winding of the target winding number is finished is considerably earlier than the time point of the next doffing, and notify the speed change to the operator by the notifying section 101.
  • a specific example of the notifying section 101 includes a patrol lamp and the like.
  • the input section 100 includes a liquid crystal display screen
  • a configuration for notifying the necessity of speed change as characters on the liquid crystal display screen may be adopted. According to such a configuration, the operator can freely set the winding speed intended by the operator.
  • the operator can set the winding speed of the automatic winder 4 to slow. Furthermore, instead of reducing the winding speed, the operator can stop the winding units 42 to which maintenance is to be performed. The winding efficiency of the automatic winder 4 is thereby lowered, but this can be canceled out with the time for which the automatic winder 4 is in a stopped state when the time point at which the winding of the target winding number is finished is considerably earlier than the time point of the next doffing. According to such a configuration, the operator can have more options, and flexible response can be made.
  • the control device 41 calculates the time point at which the winding of the target winding number is finished from the time required to process the target winding number.
  • the winding speed of the winding unit 42 is increased when the time point at which the winding of the target winding number is finished is later than the time point of the next doffing
  • the winding speed of the winding unit 42 is reduced when the time point at which the winding of the target winding number is finished is earlier than the time point of the next doffing by greater than or equal to a predetermined time
  • the winding speed of the winding unit 42 is not changed when the time point at which the winding of the target winding number is finished is the same time point as the time point of the next doffing or earlier within a predetermined time.
  • the receiving section 41c of the automatic winder 4 is configured to receive only the fact that the doffing is executed from the transmitting section 31c of the spinning machine 3. Even in the general spinning machine 3 that does not have the function of transmitting the processing status information, the completion condition information, or the doffing information relating to the time until the next doffing, only the fact that the doffing is executed (doffing execution signal) can be transmitted.
  • the control device 41 of the automatic winder 4 calculates the doffing information (time point of the next doffing or time required for one doffing) from the doffing execution signals received by the receiving section 41c in the past.
  • the doffing number (number of yarn supplying bobbins 11 which can be supplied by the spinning machine 3 in one doffing) is input from the input section 100 by the operator. That is, in the case of the present embodiment, the receiving section 41c also functions as the input section.
  • the control device 41 increases the winding speed of the winding unit 42. Furthermore, when the time point at which the winding of the target winding number is finished is considerably earlier than the calculated time point of the next doffing, the control device reduces the winding speed of the winding unit 42.
  • the optimization of the operation control of the automatic winder 4 can be realized by controlling the operation of the automatic winder 4 based on the 65046P EP spinning information input by the operator.
  • the transmission of the spinning information from the spinning machine 3 to the automatic winder 4 may not necessarily be carried out directly between the spinning machine 3 and the automatic winder 4, and for example, may be carried out via a predetermined relay device.
  • the control device 41 may control the operation of the bobbin preparing device 7 based on the processing status information.
  • the control device 41 may control the operation of each winding unit 42 based on the completion condition information.
