  The present invention relates to a method and an apparatus for measuring the sugar content of cocoons, and more particularly to a method for measuring the sugar content of cocoons and a device for measuring the sugar content of cocoons that measure the sugar content of cocoons with soil attached to the surface.

  2. Description of the Related Art Conventionally, there is known a fruit and vegetable sorting apparatus that determines the quality (sugar content, acidity, etc.) of fruits and vegetables while conveying fruits and vegetables such as strawberries one by one on a conveyor (for example, Patent Document 1). In the apparatus described in Patent Document 1, fruits and vegetables are conveyed by a conveyor, light is irradiated to the center of the fruits and vegetables by the light projecting means, and the light is measured by the light receiving means to determine the quality of the fruits and vegetables. doing. Such an apparatus for judging quality is used to set a price when a buyer buys fruits and vegetables from a farmer.

JP 2009-220043 A

As a kind of fruit and vegetables, persimmons are shipped from farmers and purchased by buyers, and then stored in the warehouse for several months. In order to prevent spoilage, they are often stored with soil attached to the surface. For this reason, the jars are shipped and purchased with soil attached to the surface. At this time, in order to set the price of koji, the quality of koji (especially sugar content in the case of koji) is determined.
However, since the soil is attached to the surface of the basket, in the fruit and vegetable sorting apparatus of Patent Document 1, the light irradiated to the fruit by the light projecting means does not reach the light receiving means, and the quality can be measured. There is a problem that you can not.

  The present invention has been made paying attention to the above-described problems, and an object thereof is to provide a sugar content measurement method and a sugar content measurement device capable of measuring the sugar content of a cocoon with soil attached to the surface.

  The sugar content measuring method of the cocoon according to the present invention measures the sugar content of the cocoon in a state where soil is attached to the surface, and the length of the cocoon is blown by blowing air toward the surface of the central portion of the cocoon A step of partially removing the soil from the center, a step of measuring the sugar content of the dredging from the portion from which the dredged soil has been removed, and spraying and adhering the soil toward the portion from which the dredged soil has been removed And measure the sugar content of the koji.

According to the above method, since the soil adhering to the surface of the straw is partially removed, it is possible to measure the sugar content of the straw from the portion from which the soil has been removed. In general, the cocoon length center portion has a lower sugar content than the end portion of the cocoon length direction. For this reason, by measuring the sugar content at the center of the length of the cocoon, the cocoon has a sugar content that is higher than the measured value at any position in the length direction, and the sugar content of the cocoon is measured higher than the actual sugar content. Can be prevented. For this reason, the soil is partially removed from the central portion of the length of the ridge, and the sugar content of the portion is measured.
In addition, if the cocoon is stored with the soil removed, the rot may occur from this portion. In the present invention, after the sugar content of the cocoon is measured, the soil is sprayed on the portion from which the soil has been removed. This prevents the spoilage of the spider during storage.

  It is preferable that the soil to be sprayed on the reed is a fine powder. According to this structure, compared with the case where the soil of a lump is sprayed on a coffin, soil becomes easy to adhere to the surface of a coffin.

  In addition, the cocoon in this invention is a crop which has a rhizome or root which becomes the edible which stored starchy material and enlarged, for example, a sweet potato, a potato, a taro, a yam, a yam, etc. are mentioned.

  The above-described object of the present invention is also achieved by a sugar content measuring apparatus for a straw that measures the sugar content of a straw that is supplied on a conveyor that constitutes a transport path and that has soil attached to the surface. An apparatus for measuring sugar content of a cocoon according to the present invention is disposed along the conveyor, and blows air toward the surface of the central part of the length of the cocoon to partially remove soil from the central part of the length of the cocoon. And a measuring device arranged along the conveyor and measuring the sugar content of the dredging from the portion where the dredged soil has been removed, and disposed at a downstream position of the measuring device along the conveyor to remove the dredged soil. A spraying device that sprays water toward the part, and a soil spraying device that is disposed in the vicinity of the spraying device along the conveyor, and sprays and attaches soil toward the sprayed portion of the dredged water. It has.

In the sugar content measuring apparatus for scissors having the above-described configuration, when the scissors with the soil attached to the surface are supplied onto the conveyor, the scissors are transported by the conveyor constituting the transport path and reach the installation position of the air spraying device. Since air is blown toward the surface of the center of the length of the cocoon by the air spraying device, the soil is partially removed from the center of the length of the heel, so the sugar content of the cocoon is reduced from the portion where the soil is removed. It becomes possible to measure, and the sugar content of the portion where the soil of the straw is removed is measured by the measuring device.
When the reed is further conveyed by the conveyor and reaches the installation position of the spraying device, water is sprayed toward the portion where the reed soil has been removed by the spraying device. Since the soil is sprayed toward the sprayed part, the soil adheres to the surface of the cocoon by water droplets. Thereby, it is possible to prevent spoilage of the straw during storage.

  According to the present invention, since the soil adhering to the surface of the straw is partially removed before the sugar content is measured, the sugar content of the straw can be measured from the portion from which the soil has been removed. In addition, if the cocoon is stored with the soil removed, the rot may occur from this portion. In the present invention, after the sugar content of the cocoon is measured, the soil is sprayed on the portion from which the soil has been removed. This prevents the spoilage of the spider during storage.

  Next, with reference to FIGS. 3-6, the sugar content measuring method using the sugar content measuring apparatus 1 of the sputum P based on this invention is demonstrated. In FIGS. 3 to 6, for the sake of simplification of explanation, the flow of processing for one ridge P is shown, but actually, a plurality of ridges P are successively conveyed by the conveyor 10. Therefore, the processes shown in FIGS. 4 to 6 are executed in parallel for each kite P. FIG. 3 is a diagram for explaining the positional relationship and operation timing of the hail detection sensor 20, the camera 30, the air spraying device 40, the measuring device 50, the spraying device 60, and the soil spraying device 70, and FIGS. 3 is a flowchart showing an operation of a control device 90.

First, an operator places the bag P on the end of the conveyor 10. At this time, the kite P is placed so that the length direction of the kite P is along the conveying direction of the conveyor 10.
Next, the control unit 91 of the control device 90 detects that the bag P is placed on the conveyor 10 and conveyed based on the detection signal transmitted from the bag detection sensor 20 (ST21). Here, the timing at which the light is blocked by the ridge P and the light receiver 22 no longer detects the light, that is, the fact that the tip in the length direction of the ridge P has reached the installation position of the heel detection sensor 20 is detected. Yes. At this timing, the controller 91 starts an internal timer T (ST22).

  The storage unit 92 of the control device 90 stores an imaging timing T1 by the camera 30 in advance. The imaging timing T <b> 1 is the timing at which the front end portion of the eyelid P in the length direction approaches the end portion in the transport direction of the visual field range R of the camera 30, i. The timing is set as follows. The imaging timing T1 is calculated from the distance dc between the front end position in the conveyance direction of the visual field range of the camera 30 and the wrinkle detection sensor 20 and a preset speed v (m / second) of the conveyor 10. = Dc / v is calculated.

  The control unit 91 calls the imaging timing T1 from the storage unit 92, and determines whether or not the timer T has reached the imaging timing T1 (ST23). When controller 91 determines that timer T is at imaging timing T1 (in the case of “YES” in ST23), camera 91 is activated to capture 芋 P and acquire an image of 芋 P (ST24). ).

The control unit 91 receives an image from the camera 30, and calculates a length L in the length direction of the heel P using a known image processing technique (ST25).
At the same time, the control device 90 calculates the sugar content measurement timing T3 of the measurement device 50. The measurement timing T3 includes the length L in the longitudinal direction of the kite P, the distance D1 between the installation position of the kite detection sensor 20 and the center position of the measurement range of the measuring device 50, and the speed v (m / Second) is calculated by the equation T3 = (D1 + L / 2) / v. Thereby, the measurement of sugar content is started when the length center part P1 of the basket P is conveyed to the center position of the measurement range of the measuring device 50.
In addition, air is blown by the air blowing device 40 immediately before the sugar content is measured to remove the soil at the central portion P1 of the length of the ridge P. The air blowing timing T2 of the air blowing device 40 is T2 = T3−. It is calculated by Δt1. Δt1 is appropriately determined according to the installation position of the air blowing device 40 with respect to the measuring device 50 or the like.

Further, the control unit 91 calculates the earth spray timing T5 of the earth spray device 70. The earth spray timing T5 is calculated from T5 = (D2 + L) from the length L in the longitudinal direction of the kite P and the distance D2 between the installation position of the kite detection sensor 20 and the center position of the spray range of the earth spray device 70. / 2) It is calculated by the equation / v Thereby, when the length center part P1 of the ridge P is conveyed to the center position of the earth spraying range of the earth spraying device 70, the spraying of the soil is started.
Moreover, water is sprayed toward the portion P2 where the soil on the surface of the central portion P1 of the length P of the ridge P is removed by the spraying device 60 immediately before the spraying of the soil, but the spray timing T4 of the spraying device 60 is T4. = T5-Δt2. Δt2 is appropriately determined according to the installation position of the spraying device 60 with respect to the soil spraying device 70 and the like.

  Further, the control unit 91 calculates the distribution timing T6 of the distribution mechanism 80. The distribution timing T6 is a distance D3 between the length L in the length direction of the basket P and the center position in the length direction of the extruded body 811 of the distribution mechanism 80 (the direction along the conveying direction of the conveyor 10). From the equation, T6 = (D3 + L / 2) / v. Thereby, when the length center part P1 of the basket P is conveyed to the center position of the extruded body 811 of the sorting mechanism 80, sorting according to the sugar content of the basket P is performed (ST26).

  Next, the control unit 91 of the control device 90 determines whether or not the timer T has reached the air blowing timing T2 (ST27). When it is determined that the timer T has reached the air blowing timing T2, the control unit 91 operates the air blowing device 40 to blow air onto the surface of the length center portion P1 of the heel P, and the length center portion of the heel P The soil adhering to P1 is partially removed (ST28).

  Next, the controller 91 of the control device 90 determines whether or not the timer T has reached the sugar content measurement timing T3 (ST29). When the control unit 91 determines that the timer T has reached the measurement timing T3, the control unit 91 operates the measurement device 50 to measure the sugar content in the portion P2 from which the soil of the length center portion P1 of the ridge P is removed, and the measurement value X Is obtained (ST30).

The control unit 91 acquires the sugar content measurement value X from the sugar content measurement unit 53 and determines the degree of sugar content of the candy P (ST31). Specifically, the control unit 91 compares the sugar content measurement value X of the length center portion P1 of the cocoon P with the sugar content reference value X0 stored in the storage unit 92 in advance, and measures the sugar content of the cocoon P measured. Determines whether the sugar content meets the standard sugar content.
If the result of determination is that the measured value X is equal to or greater than the reference value X0, the sugar content flag is set to 1 (ST32). If the measured value X is smaller than the reference value X0, the sugar content flag is set to 0 (ST33).

  Next, the controller 91 of the control device 90 determines whether or not the timer T has reached the spray timing T4 of the spray device 60 (ST34). When it is determined that the timer T has reached the spray timing T4, the control unit 91 operates the spray device 60 to spray water toward the portion P2 from which the soil on the surface of the central portion P1 of the ridge P has been removed. (ST35).

  Next, the control part 91 of the control apparatus 90 determines whether the timer T became the earth spray timing T5 of the earth spray apparatus 70 (ST36). When it is determined that the timer T has reached the soil spray timing T5, the controller 91 operates the soil spray device 70 to spray the soil toward the portion P3 where the surface water of the central portion P1 of the ridge P is sprayed. Spray and adhere (ST37).

Next, the control unit 91 of the control device 90 determines whether or not the timer T has reached the distribution timing T6 of the distribution mechanism 80 (ST38). When it is determined that the timer T has reached the distribution timing T6, the controller 91 next determines whether or not the sugar content flag is 1 (ST39). When the sugar content flag is 1, the sorting mechanism 80 is not operated, and the basket P on the conveyor 10 is conveyed to the container 2. If the sugar content flag is not 1, the control unit 91 operates the sorting mechanism 80 (ST40). Specifically, the basket P is pushed out from the conveyor 10 to the sub-conveyor 11 by the extruded body 811 of the distribution mechanism 80 and is conveyed to the sub-container 3.
Thereafter, the timer T is stopped (ST41), and the control device 90 ends the operation.

  According to the present invention, since the soil adhering to the surface of the ridge P is partially removed, the sugar content of the ridge P can be measured from the portion P2 from which the soil has been removed. Moreover, since the soil is sprayed and attached to the part P2 from which the soil is removed after the sugar content of the straw P is measured, the spoilage of the straw during storage can be prevented. Furthermore, since water is sprayed toward the portion P2 from which the soil has been removed by the spraying device 60 before the soil is sprayed, the soil tends to adhere to the surface of the ridge P.

  Moreover, the distribution mechanism 80 is not limited to the said embodiment, You may select the basket P by other known arbitrary means. Moreover, the distribution mechanism 80 can also provide a plurality of sets of the pushing member 81, the arm 82, and the drive unit 83, and can distribute the straws P according to the sugar content at a plurality of stages. That is, in the control device 90, a plurality of sugar content standards may be provided, and the straw P may be distributed according to a plurality of sugar content stages.

For example, the heel detection sensor 20 having an ultrasonic irradiation unit and a reception unit. The length of 芋 P may be obtained. The receiving unit receives the ultrasonic waves that are reflected by the ultrasonic wave irradiation unit irradiating the bag P with ultrasonic waves. The receiving unit receives the ultrasonic waves while the kite P passes the installation position of the kite detection sensor 20, and when the kite P finishes passing the installation position of the kite detection sensor 20, it rebounds from the kite PP. The incoming ultrasonic wave will not be received. The control device 90 measures the time during which the receiving unit receives the ultrasonic waves, and determines the length of the ridge P by the predetermined conveyor speed v and the time during which the ultrasonic waves are received. L is calculated.
