[Problems to be solved by the device]

 Since the conventional thread winding bobbin tray is a molded product having an integral structure, there is a problem that it is difficult to cope with changes in the inner diameter and outer diameter of the thread winding bobbin or the top shape.

That is, it was possible to deal with the change of the outer diameter and the shape of the top of the bobbin by forming the umbrella body in multiple stages of cylinders having different diameters. It was impossible to change the diameter of the protrusion provided on the upper surface, and it was not possible to change the inner diameter of the bobbin.

Therefore, when the inner diameter of the thread winding bobbin is larger than the outer diameter of the protrusion, when a large number of thread winding bobbins are stacked and packaged in a multi-layered structure, it is necessary to avoid transport between the thread winding bobbin and the tray. There was a problem that there was some play.
