First Embodiment A detecting device of a first embodiment will be described based on a drawing. FIG. 1 is a view showing a schematic configuration of a detecting device according to a first embodiment. As shown in FIG. 1 , the detecting device 1 includes a light source 10 , an imaging unit 20 , a filter 30 , and a detecting unit 40 . The detecting device 1 is a detecting device that detects the presence or absence of the object 60 by capturing the irradiated body 50 irradiated with light from the light source 10.

The light source 10 irradiates light to the object 50 to be irradiated and the object 60 disposed under the light source 10.

The irradiated body 50 is, for example, a container containing a content. Further, the object 60 is, for example, a foreign matter that may be mixed into the object 50 to be irradiated in the manufacturing step of the object 50 to be irradiated. The object 60 contains a luminescent material in advance, and the luminescent material absorbs the light emitted from the light source 10 to be excited, thereby emitting the emitted light 12 such as fluorescent light. That is, the detecting device 1 of the first embodiment detects whether or not a foreign object, that is, the object 60, is detected by detecting the emitted light 12.

The object 50 to be irradiated including the object 60 is placed on a transport mechanism 70 such as a conveyor that is configured to be movable in the horizontal direction. The transport mechanism 70 may be configured such that a plurality of irradiated bodies 50 are discharged to the lower side of the light source 10 by, for example, discharging a plurality of irradiated bodies 50 in the transport mechanism 70.

The imaging unit 20 captures the object 50 to be irradiated by the light source 10 and the object 60, and outputs the image of the object 50 to be irradiated and the object 60 to the acquisition unit 41 disposed in the detecting unit 40. In addition, the imaging unit 20 may be disposed in any manner as long as it can capture the position of the object 50 to be irradiated and the object 60 irradiated by the light source 10. For example, in the example shown in FIG. 1, the imaging unit 20 may be disposed above or to the side of the light source 10.

The detecting unit 40 detects the presence or absence of the object 60 based on the image acquired by the acquiring unit 41. Specifically, the detecting unit 40 extracts a color from the image acquired by the obtaining unit 41, and extracts an area having an image of a color corresponding to the emitted light 12, thereby detecting the presence or absence of the object 60.

The filter 30 blocks the reflected light 11 of the irradiation light reflected by the object 60 by the irradiation light from the light source 10. In the example shown in FIG. 1, the filter 30 is disposed between the light source 10 and the object 60.

For example, when there is no filter 30 between the light source 10 and the object 60, the reflected light 11 and the emitted light 12 are mixed into the detecting portion 40 at a specific ratio corresponding to the output intensity of the light source 10. However, for example, when the output of the light emitted from the light source 10 is lowered due to deterioration over time, as the light output decreases, not only the output intensity of the reflected light 11 and the emitted light 12 decreases, but also the reflected light 11 and the emitted light 12 The relative ratio may also change. When the relative ratio of the reflected light 11 and the emitted light 12 changes, the color of the light incident on the detecting portion 40 changes, which may cause erroneous detection of the object 60, but by blocking The broken reflected light 11 is incident on the detecting unit 40, and the detection accuracy of the object 60 can be improved.

Next, the configuration of the detecting device 1 of the first embodiment will be described with reference to Fig. 2 . FIG. 2 is a view showing an example of the configuration of the detecting device 1 of the first embodiment. As shown in FIG. 2, the detecting device 1 includes a light source 10, an imaging unit 20, a filter 30, a detecting unit 40, and a memory unit 44.

The light source 10 is, for example, an ultraviolet light emitting diode (LED), which is lit by electric power supplied from a lighting device (not shown), and irradiates light to the object 50 and the object 60 to be irradiated. Here, the wavelength of the light emitted from the light source 10 will be described using FIG. FIG. 3 is a view showing a spectral distribution of light emitted from the light source 10 included in the detecting device 1 of the first embodiment.

As shown in FIG. 3, the light source 10 emits, for example, light having a peak wavelength near a wavelength of 365 nm and a wavelength region of about 350 nm to 430 nm.

When the light of the light source 10 having a wavelength of around 350 nm to 430 nm is irradiated onto the object 60 as shown in FIG. 3, for example, the peak wavelength is reflected as a first wavelength at a wavelength of around 365 nm, and the wavelength region is about 350 nm. 430 nm reflected light 11. Further, the object 60 containing the luminescent substance converts the reflected light 11 into, for example, emitted light 12 having a peak wavelength as a second wavelength at a wavelength of 530 nm and a wavelength region of about 431 nm to 600 nm, and is emitted. The light is emitted 12. That is, the reflected light 11 and the emitted light 12 are emitted from the surface of the object 60 in a mixed manner.

Referring back to FIG. 2 , the imaging unit 20 includes, for example, a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS) or the like that captures an image electronically. The imaging unit 20 captures the irradiated body 50 and the object 60 that are irradiated with the light source 10 . The number of pixels of the imaging unit 20 is, for example, 5 million pixels. However, the number of pixels of the imaging unit 20 can be arbitrarily set in accordance with the size of the object to be irradiated 50 and the object 60 or the required detection accuracy.

The filter 30 blocks the reflected light 11 of the irradiation light reflected by the object 60. The filter 30 is blocked by, for example, absorbing light having a wavelength of 430 nm or less. Furthermore, the filter 30 may also contain a material that reflects the reflected light 11. In the example shown in FIG. 1, the optical filter 30 is directly attached to the imaging unit 20, for example.

Further, the detecting unit 40 includes an obtaining unit 41, an extracting unit 42, and a determining unit 43. The acquisition unit 41 acquires an image from the imaging unit 20 . The extraction unit 42 is a processing unit that extracts a pixel having a color that is recognized as a feature of a region of the object 60 from the image acquired by the acquisition unit 41. Specifically, the extraction unit 42 extracts an image having an image of a color within a predetermined range (color extraction range) set in advance in the storage unit 44 from the captured image.

The determination unit 43 determines whether or not the object 60 is present on the surface of the object 50 to be irradiated. Specifically, for example, it is determined whether or not the image region extracted by the extraction unit 42 exists repeatedly with the image of the object 50 to be irradiated. Furthermore, the determination unit 43 may determine the presence or absence of the object 60 based on whether or not the extraction unit 42 extracts an image having an image of hue, lightness, and chroma within a specified range (color extraction range).

The memory unit 44 includes a so-called non-volatile memory such as a semiconductor memory device such as a random access memory (RAM), a flash memory, or a hard disk or a compact disk. (optical disk) and other memory devices.

For example, the memory unit 44 stores information or a control program necessary for control in each part of the detecting unit 40 such as a threshold value related to the color of the incident light in the reference of the color extraction in the extraction unit 42. Further, the storage unit 44 stores information necessary for setting by each part of the detecting unit 40. The storage unit 44 can also temporarily store the captured image data acquired by the acquisition unit 41.

Further, the detecting unit 40 may be configured to be connected to the display unit 45 and the operation unit 46.

The display unit 45 is a display device for displaying various kinds of information. The display unit 45 is realized by, for example, a liquid crystal display or the like as a display device. The display unit 45 displays various screens such as an output screen input from the detecting unit 40. The display unit 45 may be configured to output, for example, information related to the detection of the emitted light 12 detected by the detecting unit 40 (for example, the position of the color-extracted region).

The operation unit 46 is an input device that accepts various operations from the user of the detecting device 1. The operation unit 46 is realized by, for example, a touch panel or the like as an input device. The operation unit 46 outputs the operation input by the user to the detection unit 40 as the operation information. For example, the detecting unit 40 controls the electric power supplied to the light source 10 in accordance with an input operation of the operation unit 46. Furthermore, the operation unit 46 may be implemented as an input device by a keyboard, a mouse, or the like. Further, the input device of the operation unit 46 may be configured to be integrated with the display device of the display unit 45.

Here, the correlation between the wavelength of light incident on the detecting device 1 and the presence or absence of the filter 30 and the luminous intensity of the light source 10 will be described with reference to FIG. FIG. 4 is an explanatory diagram showing a comparison of spectral distribution of light incident on the detecting unit 40.

As shown in FIG. 4, in the case where, for example, an ultraviolet LED having the spectral distribution shown in FIG. 3 is used as the light source 10, based on the light radiated from the light source 10 to the object 60, it has the first of about 350 nm to 430 nm. The reflected light 11 in the wavelength region 31 is incident on the imaging unit 20 and the detecting unit 40 in a mixed manner with the emitted light 12 having the second wavelength region 32 of about 431 nm to 600 nm (see the filterless filter (a)). When the light-emitting intensity of the light source 10 is reduced, the reflected light 11 and the emitted light 12 corresponding to the light-emitting intensity are mixed into the imaging unit 20 and the detecting unit 40 (refer to the filterless device (b). )).

In addition, the filter 30 blocks light having a wavelength corresponding to the first wavelength region 31 of 430 nm or less. That is, in the detecting device 1 including the optical filter 30, light having a wavelength of 430 nm or less corresponding to the first wavelength region 31 is blocked, and therefore, the intensity in the first wavelength region 31 is substantially zero (refer to Filter (A), with filter (B)). Further, the filter (A) indicates the spectral distribution after the light of the filterless (a) is incident on the filter 30. Similarly, the filter (B) indicates the spectral distribution after the light of the filterless (b) is incident on the filter 30.

As described above, in the case of no filter (a) and no filter (b), if the output intensity of the light source 10 changes, the light of the first wavelength region 31 and the light of the second wavelength region 32 will Mixed with relative values corresponding to the output intensity. In the case where the filter (a) is absent, the color of light incident on the detecting portion 40 becomes light blue. On the other hand, in the case of the absence of the filter (b), the color of the light incident on the detecting portion 40 becomes green. That is, for the detecting device not including the filter 30, even in the case where the light source 10 having the same spectral distribution is used, the object 60 is photographed in a different color, thereby easily causing the object 60 False detection.

On the other hand, in the detecting device 1 of the first embodiment, since the filter 30 blocks the light of the wavelength included in the first wavelength region 31, the object 60 is always imaged in a predetermined range of colors. Therefore, according to the detecting device 1 of the first embodiment, the detection accuracy with respect to the object 60 can be improved.

The detecting device 1 of the object 60 of the first embodiment includes the above-described configuration, and its operation will be described below. The detecting device 1 includes a light source 10, a detecting portion 40, and a filter 30. The light source 10 emits the irradiation light to the object 50 including the object 60. The detecting unit 40 detects the emitted light 12 emitted from the object 60 by the irradiation light emitted from the light source 10. The optical filter 30 is disposed between the object 60 and the detecting unit 40, and blocks the reflected light 11 of the irradiation light that is reflected by the object 60 and is advanced toward the detecting unit 40. Therefore, the detection accuracy with respect to the object 60 can be improved. The irradiation light of the X-ray inspection machine, the metal detector, or the like is transmitted, and the object 60 cannot be detected. However, the detection device 1 of the first embodiment detects the object using the light source 10 that emits light by the irradiation of the object 60. 60 is therefore suitable for detecting foreign matter as the object 60.

The reflected light 11 of the first embodiment has a first wavelength region 31 in which the first wavelength is a peak wavelength. The emitted light 12 has a second wavelength region 32 in which a second wavelength longer than the first wavelength is set as a peak wavelength. The filter 30 blocks light of a wavelength included in the first wavelength region 31. Therefore, the detection accuracy with respect to the object 60 can be improved.

Furthermore, in the above embodiment, the first wavelength region 31 and the second wavelength region 32 do not have overlapping wavelengths, but are not limited thereto. For example, a portion of the first wavelength region 31 and the second wavelength region 32 may also coincide. Even in this case, since the filter 30 blocks the light of the wavelength contained in the first wavelength region 31, the detection accuracy with respect to the object 60 can be improved.

In addition, the detecting unit 40 of the first embodiment detects the color of the emitted light 12 and detects the object 60 based on the detected color. Therefore, the detection accuracy with respect to the object 60 can be improved.

Furthermore, in the above embodiment, the detection by the detecting unit 40 for the object 60 is based on the color extraction of visible light, but is not limited thereto. For example, the object 60 can also be detected based on detection of ultraviolet light or infrared light.

In addition, the spectral distribution characteristic of the light emitted from the light source 10 is not limited to the spectral distribution characteristic, and the spectral distribution characteristic of the emitted light 12 may be emitted by the object 60 if the object 60 is irradiated. In addition, the luminescent substance contained in the object 60 is not limited to the luminescent substance, and may be a luminescent substance that emits the emitted light 12 by the irradiation light from the light source 10. In addition, the filter 30 blocks light having a wavelength of 430 nm or less, but is not limited thereto. For example, the filter 30 can block light having a wavelength of 500 nm or less, and the filter 30 can block a wavelength of 430 nm or more. Light. That is, the filter 30 can be arbitrarily set in accordance with the spectral luminosity distribution of the reflected light 11 and the emitted light 12.

[Second embodiment] Fig. 5 is a view showing a schematic configuration of a detecting device according to a second embodiment. As shown in FIG. 5, the detecting device 1A includes a light source 10, an imaging unit 20, and a detecting unit 40A. The detecting device 1A is a detecting device that detects and recognizes the presence or absence of the object 60A by capturing the irradiated body 50A that is irradiated with light from the light source 10. In FIG. 5, the same portions as those of the detecting device 1 of the first embodiment are denoted by the same reference numerals.

The light source 10 irradiates light to the object 50A to be irradiated and the object 60A disposed under the light source 10.

The object to be irradiated 50A is, for example, a food or a resin. Further, the object 60A is, for example, a fibrous substance and a bulk substance. The fibrous material and the bulk material of the object 60A contain a light-emitting component that absorbs light emitted from the light source 10 and is excited, and then emits light 12A such as fluorescent light. That is, the detecting device 1A of the second embodiment detects whether or not the object 60A is present by detecting the emitted light 12A.

The detecting unit 40A detects the presence or absence of the object 60A based on the image acquired by the acquiring unit 41. Specifically, the detecting unit 40A extracts a color from the image acquired by the acquiring unit 41, and extracts an area having an image of a color corresponding to the emitted light 12A, thereby detecting the presence or absence of the object 60A.

As described above, the object 60A contains a fibrous substance and a bulk substance. For example, when the object to be removed by the processing worker is a bulk material and the fibrous material is not the object to be removed, it is required to identify the bulk material and the fibrous material.

Therefore, the detecting unit 40A recognizes the bulk material and the fibrous material from the object 60A based on the shape of the region extracted by the color extraction. Thereby, the detecting device 1A of the second embodiment can improve the detection accuracy and the recognition accuracy with respect to the object 60A. That is, according to the detecting device 1A of the second embodiment, only the bulky substance can be identified by combining color recognition and shape recognition.

Next, the configuration of the detecting device 1A of the second embodiment will be described with reference to Fig. 6 . FIG. 6 is a view showing an example of the configuration of the detecting device 1A of the second embodiment. As shown in FIG. 6, the detecting device 1A includes a light source 10, an imaging unit 20, a detecting unit 40A, and a memory unit 44.

The extraction unit 42A includes a color extraction unit 421 and a shape extraction unit 422. The color extraction unit 421 extracts an image having an image of a color within a predetermined range (color extraction range) set in advance in the storage unit 44 from the captured image. The shape extracting section 422 extracts the contour shape of the extracted region.

The determination unit 43A determines whether or not there is a portion recognized as a bulk substance in the object 60A based on the contour shape of the region extracted by the extraction unit 42A.

Here, the difference in shape of the fibrous material and the bulk material as the object 60A will be described with reference to FIG. 7 . FIG. 7 is a view showing an example of a fibrous substance and a bulk substance contained in the object 50A to be irradiated.

In other words, in order to recognize the object 60A as the fibrous substance 61 and the bulk substance 62, it is only necessary to recognize whether the object 60A is linear or block-shaped. Therefore, when the contour shape of the region extracted by the color extraction unit 421 approximates a rectangle, the determination unit 43A recognizes whether the aspect ratio (long side/short side) of the rectangle has exceeded a predetermined threshold value to identify whether it is linear or block-shaped. In other words, when the aspect ratio (long side/short side) has exceeded a predetermined threshold value, the determination unit 43A determines that the object 60A is a linear object, that is, the fibrous substance 61. On the other hand, when the aspect ratio is equal to or smaller than the predetermined threshold value, the determination unit 43A determines that the block object 60A is the block-shaped substance 62.

In addition, the determination method of the determination unit 43A is not limited to this. For example, when the length of the long side of the region extracted by the color extraction unit 421 is approximately a predetermined value or more, the determination unit 43A determines that the fibrous substance 61 is present, and the length of the short side may be specified. When the value is equal to or greater than the value, it is determined to be the bulk material 62. Further, the threshold value or the determination method may be changed depending on the size or type of the object to be irradiated 50A.

The memory unit 44 stores, for example, a threshold value related to the color of the incident light, or a threshold value of the aspect ratio of the recognition reference in the shape extracting unit 422, which is the reference of the color extraction in the color extraction unit 421, and the like. Control the information or control programs required. Further, the storage unit 44 stores information necessary for setting by each part of the detecting unit 40A. The storage unit 44 can also temporarily store the captured image data acquired by the acquisition unit 41.

Further, the detecting unit 40A may be configured to be connected to the display unit 45 and the operation unit 46 having the same configuration as the detecting device 1 of the first embodiment.

Further, the display unit 45 may be configured to output, for example, information related to the emitted light 12A detected by the detecting unit 40A (for example, the position and the shape and size of the area). FIG. 8 is a schematic diagram showing an example of an output screen indicating the bulk material 62 recognized by the detecting device 1A of the second embodiment. As shown in FIG. 8, here, the mark 63 indicated by "+" is marked on the portion recognized as the image of the bulk material 62. Thereby, the operator who views the output screen can easily recognize the presence and position of the bulk substance 62 in the irradiated body 50A. Further, in the display unit 45, only the symbol (not shown) indicating the bulk material 62 may be marked, or the fibrous material 61 and the bulk material 62 may be distinguished and marked with a mark.

The detecting device 1A of the object 60A of the second embodiment includes a light source 10 and a detecting portion 40A. The light source 10 emits the irradiation light to the object 50A including the object 60A. The detecting unit 40A detects the color of the emitted light 12A emitted from the object 60A due to the irradiation light emitted from the light source 10, and detects the object 60A based on the detected color. Therefore, it is possible to improve the detection accuracy of the object 60A that cannot be detected by the penetration of the irradiation light of the X-ray inspection machine or the metal detector. The detecting device 1A cannot detect the object 60A such as the fibrous substance 61 or the bulk substance 62 that is penetrated by the irradiation light of the X-ray inspection machine or the metal detector, but the detecting device of the second embodiment 1A detects the object 60A by using the light source 10 that emits light by irradiation with the object 60A. Therefore, for example, the fibrous substance 61 or the bulk substance 62 is detected as the object 60A from the object 50A to be irradiated.

Further, the detecting device 1A of the second embodiment detects a region of color, and recognizes the linear object 60A (61) and the block object 60A (62) based on the shape of the detected region. Therefore, the detection accuracy with respect to the object 60A can be improved. Further, only the bulk material 62 can be recognized from the object 60A by the combination of color recognition and shape recognition.

Furthermore, the detecting device 1A of the second embodiment may also include the filter 30 included in the detecting device 1 of the first embodiment. By this, the detecting unit 40A can further improve the accuracy of detecting and recognizing the fibrous material 61, which is the linear object 60A, and the bulky object 60A, that is, the bulk material 62.

In addition, the detecting unit 40A included in the detecting device 1A of the second embodiment may be replaced by the detecting unit 40 of the detecting device 1 of the first embodiment. Thereby, the detecting unit 40 of the first embodiment can detect the area where the light 12 is emitted, and can recognize the linear object 60 and the block-shaped object 60 based on the shape of the detected area, thereby enabling The detection accuracy of the object 60 is improved.
