Accordingly, setting value information stored in the storage section of the unit controller 19 is updated (step S15). The setting management section 53A then controls the inter-machine communicating section 53C to transmit the input setting values to other automatic winders 1 (step S16).

Furthermore, in the automatic winder 1 and the automatic winder system 90 with this configuration, since the other automatic winders 1 that have received the input start information prohibit an input of setting values via the touch panel display 51, conflict in updating setting values can be prevented from occurring among a plurality of the automatic winders 1. Consequently, trouble in operation of the operator when setting various setting values (processing conditions) in a plurality of the automatic winders 1 can be reduced, and some or all of the automatic winders 1 can be prevented from being set to setting values (processing conditions) not intended by the operator.
  • the inter-machine communicating section 53C authenticates a specified user, that is, when login to the management device 50 is permitted, an input of setting values to other automatic winders 1 is prohibited.

However, in many cases, such a factory management system is arranged at a place different from a place of a factory where the automatic winder 1 is arranged. In many cases, specifications that do not allow an input in the above-described factory management system are intentionally made to prevent the input of the setting values (the update operation of the setting value information) from being executed under a state in which status of the automatic winder 1 arranged in the factory is not known. In the automatic winder 1 and the automatic winder system 90 of the above-described embodiment, great effects are obtained in particular in a case where such specifications are demanded.

For example, when reflecting the setting values while viewing status of the automatic winder 1 is desirable, the operator may perform an input to transmit as the confirmation information.
  • the setting management section 53A attaches control information to the setting values and transmits to the setting management sections 53A provided to the other automatic winders 1 (step S36) instead of merely transmitting the setting values to the other automatic winders 1.
