You will be able to synchronize.

4 is a partial enlarged view of the transfer unit of FIG. 1.

Referring to FIG. 4, the transfer unit 400 includes a pair of transfer rollers 402 that are connected to a single rotation axis and arranged so that the inclined surfaces face each other, so that the fruit can be placed on the inclined surface. A rotation shaft connected through the pair of transfer rollers 402 extends in a straight line.

Each end of the retainer 404 is connected to an outer rotational surface of the pair of transfer rollers 402. That is, the transfer roller 402 is rotatably connected to the retainer 404. Here, the retainer 404 has a'C' shape, for example.

On the other hand, the transfer unit 400 must be able to move to transfer the fruit while loading the fruit. To this end, the transfer part 400 protrudes downward from the retainer 404 and extends across the working plate 210, a slider 406 that can move in the longitudinal direction of a pair of guide bars 214 Includes.

However, as described above, in the process of changing the conveying means to the conveying part 400 of the fruit introduced in the introduction part 100, there may be a case that the fruit is not seated in the optimal position for light irradiation on the conveying part 400. have. In addition, the seating position of the fruit once seated on the transfer unit 400 does not change without other external force. In this case, the light irradiation device 1000 for irradiating the surface of the fruit according to an embodiment of the present invention is the position alignment unit described above in order to change the fruit to the optimal seating position on the transfer unit 400 for light irradiation. It is to have 250.

5 is a plan view schematically showing a working state in a fruit position alignment unit and a light irradiation unit, and FIG. 6 is a cross-sectional view schematically showing a relationship between light irradiation and light reception in a cross section taken along line VI-VI of FIG. 1 to be.

Referring to FIGS. 5 and 6, the plurality of light emitting modules 232a, 232b, 232c irradiate light so that the transported fruit is inclined downward with respect to the surface. In particular, referring to FIG. 6, a light path through which a plurality of light-emitting modules 232a, 232b, and 232c irradiates light to the surface of a fruit and a plurality of light-receiving modules 236a, 236b, and 236c receive light. The angle α formed by the traveling path of light is substantially 135 degrees. In other words, rather than irradiating the fruit vertically downward from the light emitting module and receiving the light horizontally, the fruit is irradiated horizontally by irradiating light to the fruit at an angle of 45 degrees from a vertical position, that is, at an angle of 135 degrees. When light is received, light loss is prevented and the accuracy of information obtained from light passing through the fruit is improved. Here, the reason why the fruit is irradiated with light at an angle of 135 degrees is based on the optimal light spectrum curve obtained through a number of experiments by the inventor. When the light is irradiated to the fruit vertically downward from the light emitting module, that is, when the light is irradiated at an angle of 90 degrees, the amount of light that propagates along the surface of the fruit and reaches the light-receiving unit irrespective of the light characteristics inside the fruit. It becomes significant. In this case, there is a problem that it becomes difficult to accurately measure the amount of light absorption inside the fruit. Optionally, if light is irradiated to the fruit on the other side of the light-receiving unit, that is, at an angle of 180 degrees, the amount of light passing through the inside of the fruit decreases, and the intensity of the light must be increased. There is a problem that the fruit suffers lacerations by being applied. Therefore, if light is irradiated to the fruit at an angle of 135 degrees, it is possible to increase the measurement accuracy by reducing the light that is not absorbed inside the fruit and propagates only to the surface of the fruit, and at the same time, it is not necessary to increase the amount of light, so that the laceration of the fruit can be prevented. do.

Since the angle α is an engineering numerical limitation, an error of the angle level corresponding to the tolerance is included. Therefore, that the angle α is 135 degrees in the present invention does not indicate exactly 135 degrees as a numerical value, but includes an angle error of a level that may occur during a production process or an operation process.

As shown in FIG. 5, the first light-emitting module 232a, the second light-emitting module 232b, and the third light-emitting module 232c, and the first light-receiving module 236a and the second light-receiving module corresponding thereto. (236b), and the light traveling path (arrow indicated by a broken line in FIG. 5) between the third light receiving module 236c passes through the position alignment unit 250 and is aligned to the position k2 for light irradiation. You will pass all of them.

The distance between the first light-emitting module 232a, the second light-emitting module 232b, and the third light-emitting module 232c, and the first light-receiving module 236a and the second light-receiving module 236b corresponding thereto, And the interval between the third light-receiving modules 236c is set so that light emitted from each light-emitting module must irradiate the surface of the fruit and pass through the fruit and then receive light from each light-receiving module.

Fruits that were placed at the wrong fruit position k1, not at the position for light irradiation before passing through the position alignment unit 250, pass through the position alignment unit 250 and are aligned to the position k2 for light irradiation. After that, it is placed between the light emitting unit 232 and the light receiving unit 234. That is, after passing through the position alignment unit 250, the fruit is arranged so that the long direction and the transport direction of the fruit coincide.

If the transport direction and the length of the fruit are arranged to match the length of the fruit, when all the light irradiated from the light-emitting part is received by the light-receiving part, the distance between the light-emitting modules and the distance between the light-receiving modules can be maximized. Is improved, and light analysis is possible even to a point far from the seam portion of the fruit, so that a wider range of the fruit can be photo-analyzed.

The light received by each of the light-receiving modules 236a, 236b, 236c of the light-receiving unit 234 is joined by the optical fiber 240 and sent to an optical analyzer (not shown) for light analysis. At this time, since the light received from each of the light receiving modules is joined by one optical fiber 240, the intensity of light sent from the optical fiber 240 to the optical analyzer is improved, thereby enabling more precise optical measurement.
