Corrugated tube cutting device and manufacturing method of cut corrugated tube

A corrugated tube cutting device comprising:

• a feeder feeding a corrugated tube such that an axial direction of the corrugated tube lies along a feeding path;
• a cutter cutting along a circumferential direction of the corrugated tube being fed along the feeding path;
• an imager capturing an image of a planned cutting position of the corrugated tube;
• a determiner performing image analysis of the captured image of the planned cutting position to determine whether the planned cutting position is a convex portion of the corrugated tube;
• a cutting controller that causes feeder to feed the corrugated tube for a required dimension and then causes the cutter to cut the corrugated tube at the planned cutting position when the determiner determines that the planned cutting position is a convex portion of the corrugated tube;
• and
• a regulator provided with a protrusion protruding toward the feeding path, the regulator regulating an orientation along the circumferential direction of the corrugated tube being fed along the feeding path by arranging the protrusion in a condition inserted into an interior of the corrugated tube via a running slit along the axial direction of the corrugated tube.

• wherein
• the determiner defines a partial area centered on the planned cutting position and having a width equal to a width of the convex portion of the corrugated tube as a determination target area on the captured image, and determines that the planned cutting position is the convex portion of the corrugated tube when a number of pixels originating from the corrugated tube in the determination target area is equal to or larger than a predetermined threshold, the predetermined threshold being defined according to a size of the corrugated tube.
