1. A learned model generation method of generating a learned model for maintenance of a winding apparatus including
a sheet material supplier having a first supply mechanism that supplies a first electrode sheet, a second supply mechanism that supplies a second electrode sheet, a first bonding roller that is provided on a first electrode sheet side, and a second bonding roller that is provided on a second electrode sheet side, and is paired with the first bonding roller to bond the first electrode sheet and the second electrode sheet to each other,
a first winding core,
a drive mechanism that moves the first winding core to a predetermined winding position, and winds the first electrode sheet and the second electrode sheet in an overlapping manner on the first winding core, and
a sensor that reads a first end surface of the first electrode sheet and a second end surface of the second electrode sheet along a radial direction of a first winding body in which the first electrode sheet and the second electrode sheet are wound in an overlapping manner by a plurality of turns on the first winding core, the learned model generation method comprising:
acquiring, from the sensor, first group data indicating a position of the first end surface read along the radial direction of the first winding body, and second group data indicating a position of the second end surface read along the radial direction of the first winding body;
determining whether or not the first winding body has a defect and determining whether or not a cause of the defect is the sheet material supplier when the first winding body has the defect on a basis of a positional relationship among continuous positions of the first end surface indicated by the first group data, continuous positions of the second end surface indicated by the second group data, and reference lines;
determining which of the first supply mechanism, the second supply mechanism, the first bonding roller, and the second bonding roller is the cause of the defect in a case where the determining of the cause of the defect is the sheet material supplier;
outputting information for a notification of the cause of the defect to a display apparatus; and
determining whether or not the first group data and the second group data read before the cause of the defect is maintained are used for generating the learned model on a basis of a first occurrence degree of the defect of the first winding body before the cause of the defect is maintained and a second occurrence degree of the defect of the first winding body after the cause of the defect is maintained, and generating the learned model by using the first group data and the second group data read before the cause of the defect is maintained in a case where the first group data and the second group data are used.
