Core grasping apparatus

A core grasping apparatus that grasps a core including a core main body and a core print provided at one end of the core main body, the core grasping apparatus comprising:

• a first holding device including an inflatable and deflatable first holding part, the first holding device being configured to hold the core print by inflating the first holding part so as to bring the first holding part into contact with the core print;
• a second holding device including an inflatable and deflatable second holding part, the second holding device being configured to hold the core print by inflating the second holding part so as to bring the second holding part into contact with the core print;
• and
• a turning suppression part configured to suppress the core from turning upon the core print being held by the first holding device and the second holding device, the turning suppression part applying, to the core print, a force that suppresses a turning moment acting on the core around a straight line connecting portions of the core print at which the first holding part and the second holding part respectively come in contact with the core print, wherein
• a rod-shaped member is used as the turning suppression part, and
• the rod-shaped member applies the force that suppresses the turning moment acting on the core to the core print by coming in contact with the core print at a position separated from the straight line connecting portions of the core print at which the first holding part and the second holding part respectively come in contact with the core print.

• a third holding device including an inflatable and deflatable third holding part is used as the turning suppression part, and
• the third holding part applies the force that suppresses the turning moment acting on the core to the core print by coming in contact with the core print at a position separated from the straight line connecting portions of the core print at which the first holding part and the second holding part respectively come in contact with the core print.
