Corrugated tube cutting device and manufacturing method of cut corrugated tube

Abstract

A purpose of the present invention is to provide a technology that allows corrugated tubes of various diameter sizes to be easily and reliably cut at a convex portion. In order to achieve the purpose, a cutting device is provided with 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; and an imager capturing an image of a planned cutting position of the corrugated tube. A controller performs 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 and, when a positive determination result is obtained, causes the cutter to cut the corrugated tube at the planned cutting position.

What is claimed is: 
     
         1 . A manufacturing method of a cut corrugated tube, comprising:
 (a) a step of determining whether a planned cutting position is a convex portion of a corrugated tube by capturing an image of the planned cutting position of the corrugated tube and performing image analysis of the obtained captured image; and   (b) a step of cutting the corrugated tube at the planned cutting position when the planned cutting position is determined to be a convex portion of the corrugated tube in the step (a).   
     
     
         2 . The manufacturing method of a cut corrugated tube according to  claim 1 , comprising:
 (c) a step of cutting the corrugated tube at a position that is distanced from the planned cutting position by a determined distance along an axial direction of the corrugated tube when it is determined that the planned cutting position is not a convex portion of the corrugated tube in the step (a).   
     
     
         3 . The manufacturing method of a cut corrugated tube according to  claim 1 , comprising:
 (d) a step of defining a position that is distanced from the planned cutting position by a determined distance along the axial direction of the corrugated tube as a new planned cutting position and performing the step (a) again when it is determined that the planned cutting position is not a convex portion of the corrugated tube in the step (a); and   (e) a step of repeating the step (d) until a new planned cutting position is determined to be a convex portion of the corrugated tube in the step (a).
