<p>An object of the present invention is to provide an automatic winder that allows doffers to travel and move efficiently to execute a doffing process with a high work efficiency even if two units located at mutual interference positions issue a request for a doffing process. Traveling of two doffers 4a, 4b is controlled using, as determination criteria, two elements, that is, the progress of full package production in units 2, 2 and the distance from the current position of each of the doffers 4a, 4b to the corresponding unit 2. Thus, even if two units 2, 2 located at mutual interference positions issue requests for a doffing process, respectively, doffing processes executed on the units 2, 2 by the doffers 4a, 4b can be prioritized before the doffers 4a, 4b are allowed to travel and move with a given distance maintained between them. This makes it possible to reliably prevent disadvantageous, useless traveling of the doffers 4a, 4b; each doffer 4a, 4b can be prevented from stopping or traveling in the reverse direction after approaching the other.</p> |
