After determining the top end of the actual bobbin Bf, it may be stacked by inserting into the magazine. Alternatively, a method may be adopted in which the top of the other bobbin Bf is discriminated and manually inserted into the magazine.

[0025]

Since the present invention is configured as described above, it has the following effects.

Since the bobbin supplying device is provided with a magazine for individualizing and stocking bobbins, a large-scale and complicated device such as a parts feeder for automatically individualizing bobbins is not required, and the entire device is It is possible to provide a bobbin supply system that can be downsized and that is inexpensive. In addition, inserting the bobbin into the tray, which is cumbersome and inefficient when done manually,
Since work such as lead-out processing and empty bobbin removal is automated, the load on the operator is reduced compared to an automatic winder of a system that inserts a bobbin that has been manually set-out into a magazine provided for each machine base. Therefore, the number of workers can be reduced.

When the magazine is of a rotary type, the height of the bobbin supplying device can be reduced and the workability is good.
Since the structure is simple, it is possible to supply a bobbin supply system that is low in cost and excellent in maintainability.

Further, even if the bobbin inserted on the tray is a defective bobbin or a semi-lens, all the bobbins can be taken out by the bobbin take-out machine, so that complicated control is unnecessary and control of the entire system is simplified.
