PROBLEM TO BE SOLVED: To provide a yarn winding unit having an automatic recovery function from a feeding error of a yarn feeding bobbin.SOLUTION: A winder unit forms a package by unwinding a yarn from a yarn feeding bobbin loaded in a conveyance tray. The winder unit comprises a conveyance guide, a control part, and a chase part detection sensor. The conveyance guide performs a feeding operation of feeding the yarn feeding bobbin to an unwinding position where the yarn is unwound. The control part controls the operation of the conveyance guide. The chase part detection sensor detects success or failure of the feeding operation of the yarn feeding bobbin by the conveyance guide. When the conveyance guide has performed the feeding operation (S101, S103) and then the chase part detection sensor has detected the failure of the feeding operation of the yarn feeding bobbin to the unwinding position, the control part puts the feeding operation of the conveyance guide on standby for a predetermined time (S106, S107) and then makes the conveyance guide perform the feeding operation again (S108).SELECTED DRAWING: Figure 9 |
