[0002]

2. Description of the Related Art In recent years, products such as shafts and rods made of carbon fiber have been developed and put into practical use. When manufacturing these carbon fiber products, a fiber (thread) winding device generally called a filament winding device (hereinafter simply referred to as FW device) is used.

This FW apparatus 1 has, for example, as shown in FIG. 4, a chuck 5 which is rotated by a motor Mb at one end side.
3 has a headstock 3 provided with a mandrel 61 and a tailstock 4 provided with a chuck 54 on the other end side, which is movable back and forth by a motor Ma with respect to the headstock 3. One shaft end is grasped, the other shaft end of the mandrel 61 is grasped by the chuck 54 of the tail stock 4, the mandrel 61 is rotated by the motor Mb via the chuck 53, and the yarn feeding position varying device 7 is operated from the carbon fiber supply device. It is used for winding up the carbon fiber (thread) 8 coated with the hardening material supplied through the to a predetermined diameter.

The mandrel 61 on which the carbon fiber (thread) 8 is wound is transferred from the FW device 1 to a transfer device such as a dolly and transferred to a curing furnace or the like, and a new mandrel is reassembled in the FW device 1. .

Conventionally, an overhead crane or an equivalent device (forklift, etc.) has been used to replace the mandrel, but carbon fiber products have many types of cross-sectional shapes and sizes. There are many types of shapes and sizes. Therefore, it is necessary to prepare a hanging jig in accordance with the type of the mandrel, and there is a problem that the workability of the rearrangement is poor, the downtime for the rearrangement is long, and the productivity is poor. There are problems such as increased costs and increased equipment costs such as securing storage space. In recent years, there is a strong tendency for small-lot production of other types, and in the situation where the frequency of mandrel rearrangement increases, it is required to shorten the rearrangement time in order to ensure productivity.
