Frp rebar forming apparatus

An FRP rebar forming apparatus for forming an FRP rebar from a plurality of reinforcing fiber bundles, the FRP rebar forming apparatus comprising:

• a drawing-and-twisting device configured to draw a plurality of reinforcing fiber bundles impregnated with a thermoplastic resin in a resin bath out of the resin bath while twisting the reinforcing fiber bundles;
• and a drive control device configured to control driving of the drawing-and-twisting device, wherein
• the drawing-and-twisting device includes a plurality of drawing mechanisms aligned in a drawing direction of the reinforcing fiber bundles,
• each of the drawing mechanisms includes:
• a gripping device configured to be switchable between a gripping state in which the FRP rebar is gripped and a non-gripping state in which the gripping state is released;
• a rotational drive device configured to support the gripping device and to rotationally drive the gripping device in a twisting direction of the reinforcing fiber bundles;
• and a reciprocating drive device configured to reciprocate the rotational drive device along the drawing direction, and
• the drive control device is configured to control driving of each device in each of the drawing mechanisms such that, when the gripping device switched to the gripping state is rotationally driven by the rotational drive device, forward movement driving of the rotational drive device by the reciprocating drive device is performed, and to control driving of each of the reciprocating drive devices such that forward movement driving by each of the reciprocating drive devices is started in a predetermined order.
