A package produced by a winding device such as an automatic winder is irradiated with visible light, the light reflected on the surface of the yarn layer is imaged, and this is analyzed with an image sensor to inspect the quality of the package winding shape. A device for this purpose is disclosed in Japanese Patent Laid-Open No. 61-28033.
This device is suitable for inspecting the winding shape of packages, such as stepped packages with a step in the yarn layer, or Kikumaki packages with uneven end surfaces due to eccentricity of the winding tube, etc. However, if the package is wound with threads of different thicknesses and materials, if the winding shape is good, no abnormalities can be detected. However, due to high-mix, low-volume production, for example,
When an automatic winder frequently changes the thread arrangement, threads of different thicknesses, colors, or raw materials may end up mixed into the package cage. It is difficult for an operator to visually detect such yarns of different types mixed into a package cage, and the conventional technology does not have a device for detecting this.

When the thread is exposed to ultraviolet light, it emits the absorbed energy as long-wavelength fluorescent light. The amount of this fluorescent light is unique to each yarn, so if you irradiate the package with ultraviolet light and analyze the amount of fluorescent light emitted from the yarn, you can identify abnormal package cages that contain different types of yarn. can be detected. Therefore, in order to prevent ultraviolet rays from being affected by visible light, a darkroom is formed using a light-shielding material, and a package inspection station is installed in this darkroom, and the package is housed in the darkroom for inspection. An ultraviolet light generator and a light receiver to receive the fluorescent light emitted from the package were installed.

When a package is guided to an inspection station and the package is irradiated with ultraviolet light from an ultraviolet generator, the package is irradiated with the ultraviolet light without being affected by visible light in a dark room, and the threads forming this package are It absorbs ultraviolet light and emits the absorbed energy as long-wavelength fluorescent light. If the thread forming the package is of one type, fluorescent light is emitted uniformly from the surface of the package, and a light receiver receives this light to detect that the package is normal. However, if there are two or more types of yarn forming a package cage, the amount of fluorescence generated will be irregular, and if the receiver detects this, it will detect that different types of yarns are mixed in the package cage. , automatically detect abnormal packages.

Embodiments of the device of the present invention will be described with reference to the drawings. The package inspection apparatus 1 of the present invention is comprised of an inspection station 2, a darkroom 3, an ultraviolet generator 4, and a light receiver 5. The inspection station 2 is formed by a thread winding device (not shown), and consists of a turntable 8 on which a package 7 carried by a tray 6 is placed, and a drive mechanism 9 for this turntable 8, and is installed in a darkroom 3. be. The dark room 3 is formed by covering the upper and lower surfaces and all four sides of the inspection station 2 with a light shielding material 10, and an ultraviolet generator 4 is provided on the upper surface. The ultraviolet light generator 4 uses black lights 11 made of a combination of a mercury lamp and a filter as a light source, and two black lights 11 are supported by supporting members 12 facing each other. Above this ultraviolet generator 4,
Light guide path 1 for fluorescent light emitted from package 7
3 is connected, and a fluorescent light receiver 5 is attached to this light guide path 13. Note that the device of the present invention is also integrally connected to a device for inspecting the winding shape of the package.
is equipped with a solid-state image sensor 14 for image inspection, and the light guide path 13 is equipped with a lens 15 and a reflecting mirror 16.
is built-in, and a lighting path 17 is provided back to back with the light guide path 13, and a halogen lamp 18 is attached to this lighting path 17 as a light source. 1
9 is a cooling fan, 20 is a reflecting mirror, and a shutter 22 is provided to close the visible light opening 21 during inspection using ultraviolet rays. Next, the operation of the apparatus of the present invention will be explained in detail based on the above embodiment. The package 7 is supported by the tray 6, enters the darkroom 3 via a transport path (not shown), is placed on the turntable 8 of the inspection station 2, and is placed on the drive mechanism 9.
It is rotated by. Therefore, by closing the lighting opening 21 with the shutter 22 and turning on the switch of the ultraviolet generator 4, ultraviolet rays are emitted from the black light 11 and the surface of the package 7 is irradiated with ultraviolet rays. The threads forming the package 7 absorb ultraviolet light and emit the absorbed energy as fluorescent light.
This fluorescent light passes through the light guide path 13, is refracted by the reflecting mirror 16, passes through the lens 15, and enters the light receiver 5.
Threads have different characteristics in terms of the amount of fluorescence generated depending on their material, thickness, and type.If a package cage is made of one type of thread, fluorescence will be generated by the ultraviolet rays irradiated on the rotating package cage. The amount of fluorescence is always uniform, and if the light receiver 5 detects a uniform amount of fluorescence, it is known that the inspected package is normal. In that case, shutter 22
When the camera is opened and the halogen lamp 18 is turned on, the visible light that passes through the lighting opening 21 is refracted by the reflecting mirror 20.
The surface of the package 7 is irradiated. This light is reflected on the surface of the package 7, passes through the light guide path 13, is refracted by the reflecting mirror 16, passes through the lens 15, and reaches the solid-state image sensor 14. There, the winding shape of the package is inspected. Incidentally, after the winding shape inspection, the shutter may be closed and an inspection by ultraviolet irradiation may be performed. Now, if the package 7 is made of two types of threads with different thicknesses, when this package is irradiated with ultraviolet rays, the amount of fluorescence emitted from the threads will be irregular as the package rotates. The light receiver 5 detects that abnormal fluorescence is being emitted from the package. In other words, it is detected that the package is formed of different types of threads. Packages in which an abnormality is detected in this inspection are discharged from the conveyance line.

The apparatus of the present invention introduces a package into an inspection station in a dark room, irradiates the package with ultraviolet rays, generates fluorescence from the threads forming the package, and detects the amount of fluorescence generated by a light receiver 5. With this structure, if different types of threads are mixed in a package cage, abnormal packages can be automatically detected, and when combined with a package winding inspection device that uses visible light, all packages can be inspected. Tests can be processed in one place.
