Inspection device of winding appearance of tape and improvement processing method for the same
View Patent ↗To provide a winding appearance inspection device of a tape capable of gathering a line speed in an inspection process, as well as capable of inspecting a winding appearance of the tape wound on a roll body core, even in a reel having a flange formed in a roll body core (a roll body core). Winding appearance inspection device 10 serves as a device that evaluates the winding appearance of the tape such as film T or the like wound on roll body core H, comprising light projector 12 that irradiates a light along winding surface S of the tape such as film T or the like that at least partially passes near the roll body core H, and receiver 13 that receives the light.
1. A winding appearance inspection device of a tape wound on a roll body core, comprising:
a light projector that irradiates a light that at least partially passes near the roll body core along a winding surface of the tape, such that the light is irradiated in alignment with the winding surface of the tape; and
a receiver that receives the light irradiated from the light projector.
2. The winding appearance inspection device of the tape wound on a roll body core as described in claim 1 , wherein:
the light projector irradiates light along a winding surface of the tape;
the receiver receives the light from the light projector, reflected by the tape projected from the winding surface, and
the position of the tape that projects from the winding surface is recognized by measuring the position of the light received by the receiver, a quantity of the light, or time taking the light irradiated from the light projector to be received by the receiver.
3. The winding appearance inspection device of the tape wound on a roll body core as described in claim 1 , wherein:
the light projector irradiates the light along the winding surface of the tape;
the receiver, that receives light from the light projector, focuses on the tape that projects from the winding surface, and
based on a focal distance when focalizing by the receiver, a position of the tape that projects from the winding surface is recognized.
4. The winding appearance inspection device of the tape wound on the roll body core as described in claim 1 , wherein the receiver receives light which is reflected by the roll body core or tape that projects from the winding surface of the tape, and
wherein, based on an image imaged by the receiver, the winding appearance of the tape is inspected.
5. The winding appearance inspection device according to claim 1 , wherein the light irradiated from the light projector is projected in the same direction as the winding surface of the tape, so as to pass along the winding surface.
6. The winding appearance inspection device according to claim 1 , wherein the roll body core comprises an opaque flange at respective upper and lower ends of the roll body core.
7. A winding appearance inspection device of a tape wound on a roll body core, comprising:
a light projector that irradiates a light that at least partially passes near the roll body core along a winding surface of the tape;
a receiver that receives the light irradiated from the light projector,
wherein a light-emitting face of the light projector opposes a light-receiving face of the receiver.
8. The winding appearance inspection device according to claim 7 , wherein a width of the light irradiated from the light projector extends in a range from the winding surface of the tape to a flange of the roll body core, wherein the flange opposes the winding surface of the tape.
