  • the plurality of automatic winders 60 form a network in which the winding information can be transmitted and received.
  • the winding information is transmitted and received via wireless communication by the ZigBee terminals 12 of the automatic winders 60.
  • the plurality of automatic winders 60 shown in Figure 2 are denoted by reference numerals 61, 62, 63 so as to be distinguished from one another. In the description below, the automatic winders may be specified using the corresponding reference numeral.
  • the ZigBee terminals 12 carry out communication based on the ZigBee communication standard and can thus communicate with each other. This eliminates the need to install a particular host computer or access point, allowing a network capable of direct mutual communications (what is called an ad hoc network) to be constructed. Thus, the automatic winders 60 with the ZigBee terminals 12 can transmit and receive the winding information directly to and from one another by wireless communication.
  • a plurality of the automatic winders 60 are typically arranged in parallel.
  • the distance between the frames when for example, the distance between the frames is about 2 m, the distance between the opposite ends of a frame installation space in a vertical direction of the sheet of Figure 2 may be longer than 100 m.
  • radio waves are difficult to reach the target automatic winder in the vast factory site.
  • the frames located midway between the automatic winders 60 provided at the opposite ends may interfere with the radio waves. This radio wave condition makes the communication difficult.
  • the ZigBee terminal 12 provided in each of the automatic winders 60 has an information relay function to enable information to be transmitted and received via the plurality of automatic winders 60.
  • the ZigBee terminal 12 provided in the automatic winder 60 functions as what is called a router (ZigBee router) that has a data relay function.
  • the automatic winder 60 including the ZigBee terminal 12 as a router may simply be referred to as a "router terminal”.
  • the automatic winders 60 incapable of direct communications because of the inappropriate radio wave condition can transmit and receive winding information via another automatic winder 60. Furthermore, by enabling mutual communications via a plurality of frames as described above, all the frames can be easily allowed to join the wireless communication network regardless of how or where the frames are arranged. Thus, the frames can be easily rearranged. Furthermore, since communications do not involve a host computer, a situation in which a defect in the host computer shuts down the whole network can be advantageously avoided.
  • a terminal called a coordinator starts up the network.
  • the coordinator is a terminal that controls the network.
  • the coordinator also functions as a router.
  • a specific automatic winder 60 (the ZigBee terminal 12 provided in the automatic winder 60) is preset to be a coordinator, and such an automatic winder 60 carries out a process of starting up the network.
  • the coordinator specifies an identification value called a personal area network (PAN) ID and starts the network.
  • PAN ID enables the network to be identified.
  • Each of the router terminals can join the desired network by specifying the PAN ID and then connecting to the network.
  • the automatic winder system 70 includes an alternative automatic winder 60 serving as the coordinator when the automatic winder 60 that should be serving as the coordinator cannot carry out communication.
  • an automatic winder 61 is specified as the coordinator and an automatic winder 62 is specified as a backup coordinator.
  • a first identification value is assigned to the automatic winder 61.
  • a second identification value is assigned to the automatic winder 62.
  • the first identification value is pre-stored as the PAN ID with the first-order priority
  • the second identification value is pre-stored as the PAN ID with the second-order priority, respectively.
  • the automatic winder 61 serving as the coordinator specifies the first identification value as the PAN ID to start up the ZigBee network. That is, the network with the first-order priority is started up.
  • the automatic winder 60 serving as the router monitors to check whether or not the network has been started. Upon detecting the network started based on the first identification value stored as the first-order priority and specified as the PAN ID, the automatic winder 60 joins the network.
  • the automatic winder 62 serving as the backup coordinator monitors to check whether or not any network with the first identification value specified as the PAN ID is present, for a predetermined period of time after the power is turned on. If the automatic winder 62 detects a network with the first identification value specified as the PAN ID within the predetermined period of time, the automatic winder 62 joins the network as a normal router.
  • the automatic winder 62 serving as the backup coordinator starts up the network with the second identification value specified as the PAN ID. That is, the automatic winder 62 starts up the network with the second-order priority.
  • the automatic winder 60 serving as the router joins the network with the second-order priority.
  • each of the router terminals can communicate via a plurality of other router terminals. Furthermore, the network is first started up by the coordinator. Thus, each router terminal first attempts to connect to the coordinator. However, due to the ratio wave conditions or the like, there are cases in which a router terminal cannot communicate directly with the coordinator. In such cases, the router terminal joins the network via a different router terminal that has already joined the network.
  • the network for the automatic winder system 70 is conceptually formed like a tree around the coordinator.
  • a "parent terminal” is defined as a router terminal which the certain router terminal communicates when carrying out communication with the coordinator.
  • a "child terminal” is defined as a router terminal which carries out communication with the coordinator via the certain router terminal.
  • the parent terminal for a certain router terminal is disconnected from the network and cannot carry out communication, the certain router terminal and all the child terminals communicating via the certain router terminal fail to connect to the network.
  • the reason for this situation is expected to be that for example, the automatic winder 60 as the parent terminal has been powered off or the ZigBee terminal 12 in the automatic winder 60 as the parent terminal becomes defective.
  • the above-described problem may also result from rearrangement of the frames or the like that may cause changes in the radio wave condition to prevent communication from being carried out with the parent terminal. In this case, if re-starting of the network and re-setting of the parent-child relationship are necessary every time when the communication becomes incapable, such operation would be cumbersome to the operator. This also reduces the productivity of the factory as a whole.
  • the automatic winder system 70 is configured to automatically re-set the parent-child relationship.
  • this parent-child relationship re-setting process will be described.
  • Figure 3 shows the flow of a parent-child relationship re-setting process program executed when a router terminal belonging to the network for the automatic winder system 70 according to the present embodiment transmits winding information.
  • the router terminal Before transmitting the winding information, the router terminal attempts to communicate with the parent terminal (step S101). The router terminal checks the presence or absence of a response from the parent terminal and the contents of the response to determine whether or not the communication is appropriate (step S102). If the router terminal can communicate appropriately with the parent terminal, the network can be maintained as it is. Thus, the flow is terminated with no particular process carried out. The winding information is transmitted to the parent terminal.
  • the router terminal determines whether or not the router terminal has any child terminal (step S103). If a child terminal is present, the router terminal carries out a process of unlinking the child terminal from the router terminal (step S104).
  • the router terminal is unlinked from the parent terminal (step S105), and searches for a new parent terminal to link the router terminal to the parent terminal (step S106). Thereafter, the router terminal transmits the winding information to the new parent terminal.
  • the router terminal can communicate with the child terminal, then the router terminal can omit the processing in step S104 and join and link to the new parent terminal together with the child terminal.
  • a determination that the communication with the current parent terminal becomes incapable means that the radio wave condition is likely to have been changed by rearrangement or the like.
  • the router terminal allows each of the child terminals to unlink from the router terminal and to re-search for a parent terminal. Then, the network can be reconstructed with a more optimum path.
  • the child terminal unlinked by the processing in step S104 searches for a parent terminal according to the flowchart shown in Figure 3 as described above.
  • the network for the automatic winder system 70 has a self-improvement function and a self-repair function. Consequently, the wireless communication network can always be maintained in a proper condition without requiring an operator to set the communication channel.
  • winding information can be accumulatively transmitted between the automatic winders 60. Specifically, when a certain automatic winder 60 receives winding information from another adjacent automatic winder 60 and then transmits the winding information to yet another adjacent automatic winder 60, the certain automatic winder 60 can add the winding information managed by the certain automatic winder 60 to the received winding information and transmit such winding information.
  • the automatic winders 60 included in the automatic winder system 70 can efficiently share the winding information. Meanwhile, at least one automatic winder 60 can be used as a central managing device so as to allow the information from the communicably connected automatic winders 60 to be intensively managed.
  • the wireless communication network is configured as described above so as to allow the automatic winders 60 to transmit and receive the winding information to and from one another. This facilitates management of the factory as a whole.
  • the yarn winding conditions can be set collectively. Furthermore, by the transmission and reception of the winding information as described above, the yarn winding state information and statistical information on all the frames can be appropriately monitored on the display 13 of any automatic winder 60. Thus, the operator can check, on the display 13 of the nearest automatic winder 60, information indicating that for example, the production rate of the X-th yarn winding unit 16 provided in the automatic winder 63 is inefficient, without moving to an area where such automatic winder 63 is installed.

That is, for example, before the winding information managed by the frame control device 11 provided in the automatic winder 61 is transmitted to the frame control device 11 in the automatic winder 62, the ZigBee terminal 12 provided in the automatic winder 61 determines whether or not communication can be carried out with the frame control device 11 in the automatic winder 62 (step S102). When communication can be carried out with the frame control device 11 in the automatic winder 62, the ZigBee terminal 12 in the automatic winder 61 transmits the winding information managed by the frame control device 11 in the automatic winder 61 to the frame control device 11 in the automatic winder 62.
  • the ZigBee terminal 12 in the automatic winder 61 searches for and communicates with a frame control device provided in an automatic winder different from the automatic winder 62 (for example, the frame control device 11 provided in the automatic winder 63) (step S106).
  • the automatic winder system 70 includes an automatic winder 60 that cannot carry out communication (in the above-described example, the automatic winder 62), the automatic winder system 70 enables communication to be carried out with another automatic winder 60 by skipping the automatic winder 60 that cannot carry out communication.
  • the communication path can be automatically reconstructed.
  • the automatic winders 60 can be more easily rearranged, and the communications throughout the system can be prevented from being shut down as a result of the defect in the communication function of the particular automatic winder 60. This further improves the productivity.
  • each of the automatic winders 60 includes the ZigBee terminal 12 using ZigBee as a wireless communication standard.
  • ZigBee is a short-distance wireless communication standard.
  • the plurality of automatic winders 60 can be connected together so as to be capable of communicating consecutively with one another via the ZigBee terminals 12.
  • the ZigBee terminals 12 can communicate with each other and consume a reduced amount of power.
  • the transmission distance of the ZigBee terminals 12 is appropriate for use in a vast factory site.
  • the ZigBee terminals 12 enable communication via a plurality of textile machines and can thus communicate with each other in a vast factory site.
  • the ZigBee terminal 12 is particularly suitably used for the automatic winder system 70.
  • the automatic winder 60 includes the plurality of yarn winding units 16. Furthermore, the automatic winder 60 includes the ZigBee terminal 12 that can perform at least one of transmission and reception of information directly to and from another automatic winder 60.
  • a plurality of the automatic winders 60 configured as described above are installed so as to communicate with one another. Accordingly, the automatic winders 60 can communicate with one another without the intervention of a host computer.
  • a communication network for the automatic winders 60 can be constructed in which the positions of the automatic winders 60 can be easily rearranged.
  • the winding information described above is only an example. Another type of information may be communicated among the automatic winders. Furthermore, only a part of the winding information may be communicated, with the remaining part not communicated. For example, the configuration may be modified such that only the yarn winding conditions are communicated among the automatic winders 60.
  • the supply device 52 and the automatic doffing device 51 may be omitted or modified.
  • the configuration in which the yarn supplying bobbin 21 is supplied by the supply device 52 may be changed to a configuration in which a magazine type bobbin supply device is provided on a front side of each of the yarn winding units 16.
  • the wireless communication standard is not limited to ZigBee but may be changed to another wireless communication standard, for example, Bluetooth.
  • Bluetooth slave terminals can communicate with a master terminal but the slave terminals cannot communicate with each other. Further, only one master terminal is provided in the network. With Bluetooth, only a small number of slave terminals, that is, only seven slave terminals can be connected to a single master terminal, and a communication distance is limited. Therefore, it may be difficult to adopt Bluetooth for communications among a large number of frames in a large space such as in a textile factory. Thus, to enable communication to be carried out among the frames in the textile factory, ZigBee can be particularly suitably used in terms of the flexibility of expansions and changes and fault resistance.
  • the ZigBee terminal 12 may be connected to, for example, a wired LAN port.
  • the ZigBee terminal 12 may be irremovable from the automatic winder 60 rather than being removable from the automatic winder 60. However, in terms of expandability and flexibility, the ZigBee terminal 12 is preferably removable from the automatic winder 60.
  • the mounting position of the ZigBee terminal 12 is not limited to the positions shown in Figures 1 and 2 .
  • the ZigBee terminal 12 may be mounted on a top surface of the frame control device 11 or built in the frame control device 11.
  • the configuration in which the flow in Figure 3 is carried out to transmit information may be changed such that the flow is periodically carried out.
  • two automatic winders 60 serve as the coordinators (one main coordinator and one backup coordinator). However, any number of backup coordinators may be provided.
  • the area where the coordinators are installed is not particularly limited. Any of the automatic winders 60 may be set to be the coordinators.
  • an automatic winder started first in the automatic winder system may be configured to function dynamically as the coordinator.
  • the textile machine is not limited to the automatic winder but may be a spinning machine including at least one spinning unit. In this case, spinning information on each spinning unit is transmitted to and received from another spinning machine.
  • the textile machine system is not limited to the communication between the frames of the same type but may be configured to include, for example, a plurality of automatic winders and a plurality of spinning machines. This configuration allows information to be consistently managed from yarn spinning to package production.
