Description

Food inspection device
Technical Field
Embodiments of the present invention relate to a food inspection apparatus.
Background
In the food market, safety awareness of food is increasing with coping with Hazard Analysis, critical Control Point (HACCP), and the like. In addition, there is also a problem in the food market such as food loss due to rotting or the like. Food loss occurs in various supply chains of food production, processing, retail sale, consumption, and the like, and also becomes a social problem.
Therefore, for example, a technique has been proposed in which ultraviolet light is irradiated onto the surface of an agricultural product to excite and emit light at a damaged portion or a diseased portion of the surface of the agricultural product, thereby determining the presence or absence of an abnormality. In addition, a technique has also been proposed in which white light is irradiated onto the surface of agricultural products before irradiation of ultraviolet rays, and the range of inspection by ultraviolet rays is detected.
However, in the inspection using only ultraviolet rays, it is difficult to inspect various foods. In this case, various foods can be inspected by performing inspection using a Hyperspectral camera (Hyperspectral camera), but this leads to an increase in the price of the inspection apparatus.
Therefore, it is desired to develop a food inspection apparatus capable of inspecting various foods with a simple configuration.

Detailed Description
Hereinafter, embodiments will be described by way of example with reference to the accompanying drawings. In the drawings, the same components are denoted by the same reference numerals, and detailed description thereof will be omitted as appropriate.
Fig. 1 is a schematic view illustrating a food inspection device 1 according to the present embodiment.
As shown in fig. 1, the food inspection apparatus 1 (hereinafter, simply referred to as the inspection apparatus 1) includes, for example, a supply unit 10, a moving unit 20, an inspection unit 30, an accommodating unit 40, and a controller 50.
The supply unit 10 may be provided near an end of the moving unit 20 on the carrying-in side. The supply unit 10 accommodates a plurality of inspection objects 100 therein, and supplies the accommodated inspection objects 100 to the moving unit 20. For example, the supply unit 10 may include a hopper for storing a plurality of inspection objects 100 and a supply device for taking out the inspection objects 100 stored therein and supplying the inspection objects to the moving unit 20.
The configuration of the supply unit 10 is not limited to the illustrated configuration. The supply unit 10 may supply the test objects 100 to the moving unit 20 so that the test objects 100 do not overlap each other.
The supply unit 10 is not essential and may be omitted. When the supply unit 10 is omitted, for example, the operator may supply the inspection object 100 to the moving unit 20.
Here, the inspection object 100 may be a food. The inspection object 100 may be, for example, a food contained in a packaging film, a tray, a container, or the like that can transmit at least one of visible light and ultraviolet light, or a food that is not contained in a packaging film or the like.
The food is, for example, agricultural products, meat raw materials, fresh fish raw materials, processed foods, etc.
Further, the "agricultural product" may be, for example, a plant that is artificially cultivated and harvested or a plant that is grown and harvested in nature. "agricultural products" can also be obtained by farming for cultivating and harvesting cultivated plants in a planned manner, harvesting of plants naturally growing in nature (harvesting of wild plants), so-called semi-cultivation for growing and harvesting in an intermediate state between cultivation and wild, and the like. The use of the "agricultural product" is not particularly limited, and various uses such as food, medicine, and ornamental use can be considered.
The "processed food" is, for example, a home dish, a lunch, salad, etc.
The food is not limited to the exemplified food, and may be any food having a consumption period, for example.
The moving unit 20 moves the inspection object 100 supplied from the supply unit 10.
The moving unit 20 may be provided between the supply unit 10 and the receiving unit 40, for example. The moving unit 20 may be a belt conveyor, a roller conveyor, or the like.
Further, although the case where the moving unit 20 moves the inspection object 100 in the horizontal direction is illustrated, the moving unit 20 may move the inspection object 100 in a direction inclined with respect to the horizontal direction.
The moving unit 20 is not essential and may be omitted. For example, a table on which the inspection object 100 is placed may be provided instead of the moving unit 20.
The inspection unit 30 is provided on one side of the inspection object 100 in a direction intersecting the moving direction of the inspection object 100. The inspection unit 30 may be disposed above the moving unit 20, for example. The inspection unit 30 is provided, for example, between the supply unit 10 and the accommodation unit 40 in the moving direction of the inspection object 100.
The inspection unit 30 irradiates one side of the inspection object 100 with at least one of light in the visible light and ultraviolet region (hereinafter, simply referred to as ultraviolet light).
Fig. 2 is a schematic diagram illustrating the inspection unit 30.
Fig. 2 isbase:Sub>A schematic view of the inspection unit 30 in fig. 1 as viewed from the linebase:Sub>A-base:Sub>A.
As shown in fig. 2, the inspection unit 30 includes, for example, an imaging unit 31, a light source 32, a detection unit 33, and a circuit unit 34.
The imaging unit 31 images the inspection target 100 immediately before the inspection, for example. The imaging unit 31 may be, for example, a Charge-Coupled Device (CCD) camera or the like capable of imaging a color image of the inspection target 100. The imaging unit 31 is provided, for example, between the supply unit 10 and the light source 32 and the detection unit 33 in the moving direction of the inspection object 100. In this way, the imaging unit 31 can image the inspection target 100 before the inspection by the light source 32 and the detection unit 33. The image data of the inspection object 100 captured by the imaging unit 31 is input to the controller 50.
The light source 32 irradiates at least one of visible light and ultraviolet light based on a signal from the controller 50, and changes the wavelength of the irradiated visible light.
The light-emitting body used in the light source 32 is not particularly limited as long as it is a light-emitting body that irradiates light of a predetermined wavelength. For example, the light-emitting body may be a light-emitting element such as a light-emitting diode, a laser diode, or an organic light-emitting diode, or may be a discharge lamp that irradiates ultraviolet light. However, if the light emitting element used in the light source 32 is a Light Emitting Diode (LED), it is possible to achieve cost reduction, size reduction, long life, energy saving, and the like.
Therefore, a case where the light emitting body used in the light source 32 is an LED will be described below as an example.
The light source 32 has, for example, at least any one of a full-color LED and an ultraviolet LED. Instead of the full-color LED, the light source 32 may have a red LED, a green LED, and a blue LED. The light source 32 may further include LEDs for emitting visible light other than red, green, and blue.
For example, the full-color LED and the red LED may be configured to emit light having a peak wavelength of about 630 nm. For example, the full-color LED and the green LED may be configured to irradiate light having a peak wavelength of about 525 nm. For example, the full-color LED and the blue LED may be configured to emit light having a peak wavelength of about 455 nm.
For example, the ultraviolet LED may be configured to irradiate ultraviolet rays having a peak wavelength of about 280nm to 400 nm.
The number and arrangement of the full-color LEDs and the ultraviolet LEDs may be changed as appropriate depending on the size of the inspection object 100. For example, a plurality of full-color LEDs and a plurality of ultraviolet LEDs may be arranged in a matrix or concentrically.
The number and arrangement of the red LEDs, green LEDs, blue LEDs, and ultraviolet LEDs may be appropriately changed according to the size of the inspection object 100. For example, a plurality of red LEDs, a plurality of green LEDs, a plurality of blue LEDs, and a plurality of ultraviolet LEDs may be arranged in a matrix or on concentric circles.
The detection unit 33 detects at least one of visible light and ultraviolet light emitted from the light source 32 and reflected by the object 100 to be inspected. The detection unit 33 may be, for example, a CCD camera or the like capable of capturing at least one of an image of visible light and an image of ultraviolet light. In this case, the detection unit 33 may include, for example, a CCD camera for detecting a color image and a CCD camera for detecting an ultraviolet image.
The data of the reflected light detected by the detection unit 33 is input to the controller 50 via the circuit unit 34.
The circuit section 34 controls the light source 32 based on a signal from the controller 50. For example, the circuit unit 34 causes the light source 32 to emit at least one of visible light and ultraviolet light of a wavelength specified by the controller 50. When visible light is irradiated from the light source 32, light may be irradiated from a full-color LED or at least any one of a red LED, a green LED, and a blue LED.
In the case of a full-color LED, the wavelength of the visible light or the intensity of the light to be irradiated can be controlled by selecting a terminal to which a voltage is applied or increasing or decreasing the applied voltage.
In the case of the red LED, the green LED, and the blue LED, the wavelength of the visible light to be irradiated or the intensity of the light can be controlled by selecting the LED to which the voltage is applied or increasing or decreasing the applied voltage.
The details of the control of the visible light and the ultraviolet light to be irradiated will be described later.
Further, a sensor 35 for detecting the position of the inspection object 100 may be further provided. The sensor 35 is provided, for example, to determine the imaging timing by the imaging unit 31, to determine the irradiation timing by the light source 32, or to switch between the start of irradiation and the stop of irradiation. For example, as shown in fig. 1, the sensor 35 may be provided on the upstream side of the inspection portion 30 and in the vicinity of the inspection portion 30. The form of the sensor 35 is not particularly limited. The sensor 35 may be, for example, an optical sensor, an ultrasonic sensor, a proximity sensor, or the like.
The accommodating unit 40 accommodates the inspection object 100a after the inspection. The housing portion 40 is provided, for example, in the vicinity of the end portion of the moving portion 20 on the discharge side. The storage portion 40 is, for example, a dish (container). Further, a storage unit for storing the inspection object 100a determined as "no abnormality" during the inspection and a storage unit for storing the inspection object 100a determined as "abnormality" may be provided separately. In this case, a device for distributing the inspection target objects 100a may be provided in the moving unit 20 based on the inspection result. The examination object 100a may be assigned by an operator, a robot, or the like.
The controller 50 controls the operation of each element provided in the inspection apparatus 1. The controller 50 includes an arithmetic element such as a Central Processing Unit (CPU) and a memory element such as a semiconductor memory. The controller 50 is, for example, a computer. The storage device may store, for example, a control program for controlling the operation of each element provided in the inspection apparatus 1. An input device such as an operator for inputting data such as inspection conditions may be connected to the controller 50. A display device that displays an operation state, an abnormality warning, and the like may also be connected to the controller 50.
Next, the operation of the inspection apparatus 1 will be described.
For example, the controller 50 controls the supply unit 10 and supplies the inspection object 100 to the moving unit 20.
For example, the controller 50 controls the moving unit 20 to move the inspection object 100 to the inspection unit 30.
When the sensor 35 detects that the inspection target 100 is carried into the imaging area of the imaging unit 31, the controller 50 causes the imaging unit 31 to image a color image of the inspection target 100, for example. The data of the captured color image is input to the controller 50.
Here, abnormal portions such as a damaged portion, a disease-damaged portion, and a rotten portion may occur on the surface of the object 100. For example, the dominant color of the abnormal portion is different from the dominant color of the normal portion (the original color of the inspection object 100) in at least one of hue, brightness, and chroma. In addition, the area of the abnormal portion is generally smaller than that of the normal portion.
Therefore, by analyzing at least one of hue, brightness, and chroma in the color image of the inspection object 100, the dominant color of the normal portion or the dominant color of the abnormal portion can be obtained.
In this case, for example, the hue, brightness, and saturation having the highest value or the hue, brightness, and saturation of a portion having a large area may be set as the dominant hue, brightness, and saturation of a normal portion. For example, the hue, brightness, and saturation of the lowest value or the part having a small area may be set as the dominant hue, brightness, and saturation of the abnormal part.
The dominant color of the normal portion and the dominant color of the abnormal portion may be determined in advance. In this case, data of at least one of the hue, brightness, and chroma of the dominant color of the normal portion, which is obtained in advance, may be input to the controller 50. Data of at least one of hue, brightness, and chroma of the dominant color of the abnormal portion, which is obtained in advance, may be input to the controller 50. The controller 50 may also input data of a normal portion and data of an abnormal portion, which are obtained in advance.
When these data are obtained in advance, the imaging unit 31 may be omitted. However, if the imaging unit 31 is provided, the dominant color of the normal portion or the dominant color of the abnormal portion of the inspection object 100 immediately before the inspection can be obtained. Therefore, the inspection closer to the actual situation can be performed.
The controller 50 obtains the wavelength of visible light that most emphasizes the dominant color of the normal portion based on the dominant color of the normal portion obtained by analyzing the data captured by the imaging unit 31 or the dominant color of the normal portion obtained in advance and input to the controller 50. The wavelength of visible light that most emphasizes the dominant color of the normal portion can be set to, for example, the wavelength of visible light whose hue, brightness, and chroma become the highest when the normal portion is irradiated with sunlight. For example, when the test object 100 is a strawberry, the wavelength of red light is obtained.
The controller 50 can also determine the wavelength of visible light that best highlights the dominant color of the abnormal portion.
For example, when the wavelength of the visible light that most emphasizes the dominant color of the normal portion is determined, the wavelength of the color having a complementary color relationship with the determined color of the visible light may be set as the wavelength of the visible light that most emphasizes the dominant color of the abnormal portion. In this way, the arithmetic processing in the controller 50 becomes easy.
Further, the wavelength of visible light that most emphasizes the dominant color of the abnormal portion may be determined based on the dominant color of the abnormal portion obtained by analyzing the data captured by the imaging unit 31 or the dominant color of the abnormal portion input to the controller 50, which is determined in advance. The wavelength of the visible light that most emphasizes the dominant color of the abnormal portion may be, for example, the wavelength of the visible light that has the highest hue, brightness, and saturation when the abnormal portion is irradiated with sunlight.
Further, when ultraviolet rays are irradiated, abnormal portions such as damaged portions, portions affected by diseases, rotten portions, and the like can be made to protrude. However, depending on the type of the inspection object 100, the degree of the abnormal portion, and the like, the abnormal portion may not be projected even when the ultraviolet ray is irradiated.
Therefore, the irradiation of the visible light and the irradiation of the ultraviolet light, which make the dominant color of the abnormal portion most prominent, may be selectively switched. For example, the operator may appropriately switch between irradiation with visible light and irradiation with ultraviolet light according to the judgment of the operator, the results of experiments or simulations, or the like.
For example, the controller 50 may compare image data when the visible light with the most prominent dominant color of the abnormal portion is irradiated with image data when the ultraviolet light is irradiated with the image data, and switch the irradiation to the irradiation for more easily determining the abnormal portion.
For example, the irradiation of visible light and the irradiation of ultraviolet light for making the dominant color of the abnormal portion most prominent may be performed sequentially or simultaneously, and image data for which the abnormal portion is more easily determined may be set as the determination target.
For example, the controller 50 controls the circuit unit 34 so that at least one of visible light and ultraviolet light that most emphasizes the main color of the normal portion is irradiated from the light source 32.
For example, the circuit unit 34 causes the light source 32 to emit at least one of visible light and ultraviolet light that most emphasizes the dominant color of the normal portion, based on a signal from the controller 50.
For example, the controller 50 controls the circuit unit 34 so that at least one of visible light and ultraviolet light that most emphasizes the dominant color of the abnormal portion is irradiated from the light source 32.
For example, the circuit unit 34 causes the light source 32 to emit at least one of visible light and ultraviolet light that most emphasizes the dominant color of the abnormal portion, based on a signal from the controller 50.
As described above, the controller 50 emits visible light from the light source 32 at a wavelength that most emphasizes the dominant color of the normal portion of the inspection object 100. Alternatively, the controller 50 irradiates visible light of a wavelength that most emphasizes the dominant color of the abnormal portion of the inspection object 100 from the light source 32.
The controller 50 may obtain at least one of a wavelength that best highlights the dominant color of the normal portion of the inspection target 100 and a wavelength that best highlights the dominant color of the abnormal portion of the inspection target 100 based on the image data input from the imaging unit 31.
At least one of the visible light and the ultraviolet light emitted from the light source 32 and reflected on the surface of the object 100 to be inspected is detected by the detection unit 33. The data detected by the detection unit 33 is input to the controller 50 via the circuit unit 34.
For example, the controller 50 determines whether or not there is an abnormal portion and at least one of the degree of the abnormal portion based on the data input from the detection unit 33.
When visible light that most highlights the dominant color of the normal portion is irradiated, the range, size, and the like of the normal portion become clear. Therefore, when the range, size, or the like of the normal portion is larger than a predetermined threshold value, it can be determined that there is no abnormal portion or that the size, degree, or the like of the abnormal portion is within an allowable range.
When visible light that most highlights the dominant color of the abnormal portion is irradiated, the range, size, and the like of the abnormal portion become clear. Therefore, when the range, size, or the like of the abnormal portion is larger than a predetermined threshold value, it can be determined that there is an abnormal portion or that the size, degree, or the like of the abnormal portion exceeds the allowable range.
When ultraviolet light is irradiated, the range, size, and the like of the abnormal portion become clear. Therefore, when the range, size, or the like of the abnormal portion is larger than a predetermined threshold value, it can be determined that there is an abnormal portion or that the size, degree, or the like of the abnormal portion exceeds the allowable range.
For example, the controller 50 may temporarily stop the moving unit 20 or temporarily decrease the moving speed when the inspection of the inspection target 100 is performed. In this case, the controller 50 may restart the movement or restore the movement speed when the inspection of the inspection object 100 is ended.
For example, the controller 50 controls the moving unit 20 to move the inspection object 100a, which has been inspected, to the accommodating unit 40. When the moving unit 20 is provided with a device for assigning the inspection object 100a based on the inspection result, the controller 50 controls the assigning device so that the inspection object 100a determined as "no abnormality" and the inspection object 100a determined as "abnormality" can be accommodated in the accommodating units 40. When the operator performs the assignment of the inspection target 100a, the controller 50 may issue a warning or the like to notify the operator that the inspection target 100a is determined to be "abnormal".
The inspection apparatus 1 of the present embodiment is provided with a light source 32 capable of changing the wavelength of the visible light to be irradiated. For example, the light source 32 can emit at least one of visible light and ultraviolet light. Therefore, the controller 50 can irradiate at least any one of light that most emphasizes the dominant color of the normal portion and ultraviolet rays from the light source 32. Alternatively, the controller 50 may irradiate at least one of light and ultraviolet rays from the light source 32, which make the dominant color of the abnormal portion most prominent.
Therefore, the presence or absence of an abnormal portion and the degree of the abnormal portion can be determined more accurately.
That is, according to the inspection apparatus 1 of the present embodiment, various foods can be inspected with a simple configuration.
Further, by providing the imaging unit 31, the dominant color of the normal portion or the dominant color of the abnormal portion of the inspection target 100 immediately before the inspection can be obtained. Therefore, the inspection closer to the actual situation can be performed.
While the present invention has been described with reference to the preferred embodiments, it is to be understood that the present invention is not limited to the disclosed embodiments. These new embodiments can be implemented in other various ways, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalent scope thereof. In addition, the embodiments described above may be implemented in combination with each other.
