Abstract:
To provide a manufacturing apparatus of a cylindrical body capable of reducing waste amount, a control method of a manufacturing apparatus of a cylindrical body, and control program of a manufacturing apparatus of a cylindrical body.SOLUTION: A manufacturing apparatus 100 of a cylindrical body contains: an injection molding apparatus 1 which sends an injection-molded cylindrical molding BT in a feed-out direction AR1 continuously; a defect detector which detects a surface defect of the molding BT passing by a detection position F1 in the feed-out direction AR1; and a cut part 3 which cuts a cylindrical body away from the molding BT. The manufacturing apparatus 100 of the cylindrical body cuts a cylindrical body containing a portion of a desired length away from the molding BT in a case that a portion of a desired length in the molding BT passes by the detection position F1 without detecting a defect.The manufacturing apparatus 100 of a cylindrical body cuts a defect-containing cylindrical body away from the molding BT in a case that a defect is detected before a portion of a desired length in the molding BT has passed by the detection position F1. The length of the defect-containing cylindrical body is shorter than the nondefective length which is the length of the cylindrical body containing a portion of desired length.SELECTED DRAWING: Figure 3
