2. Description of the Related Art In general, in conventional fruit sorting, only the appearance such as the size, weight, color and degree of scratches is often used as a reference. Fruit grades are given based on appearance and commercialized. In such a sorting method, the fruit conveyed by the conveyor is judged based on the appearance, and the only method is to rely on manual operation one by one.

However, in the method of sorting fruits only by appearance, it is not possible to evaluate the actual taste such as sugar content and acidity even if the fruit is refined due to its appearance due to the characteristics of the fruit. As a result, the actual valuation of products was often inappropriate. Nevertheless, confirming the taste of the fruit before shipping will leave scars on the fruit, causing problems in storage and distribution.

[0004] In order to solve this problem, there has been conventionally used a machine which transmits light to a fruit without damaging the fruit, measures appearance, sugar content, acidity, and the like, and sorts the fruit according to the values. The method of measurement by this machine emits light at a predetermined position on fruits conveyed on a conveyor,
This is a method of sorting fruits based on this optical information. The selected fruits are then discharged by grade.

However, the problem with the above method is that light is scattered in the process of transmitting light, and the amount of transmitted light is not constant. Errors are likely to occur in the process of sorting based on the measured values. Also, the amount of light that can be caught by the sensor is reduced by the amount of the dispersed light. For this reason, accuracy in fruit sorting is reduced, and errors may frequently occur when giving grades.

Further, in the above-mentioned conventional method, the sugar content and the acidity of the fruit are measured based on the reflected light among the transmitted light, so that the taste cannot be sufficiently measured even inside the fruit. . This is also a factor that reduces the accuracy of sorting. An object of the present invention is to solve the conventional problems as described above.

SUMMARY OF THE INVENTION The present invention relates to a non-destructive fruit sorter. More specifically, light is instantaneously transmitted through the fruits carried by the conveyor. Then, the light reaches the optical cable. The light reaching the optical cable is caught by the sensor according to the degree to which the components inside the fruit accept the light. The sensor recognizes and separates the captured optical information. A controller coupled to the sensor analyzes the optical information and measures the sugar and acidity of the fruit. Fruits are sorted according to certain grades according to the pre-input measurements.

The power of the sorting machine (1) is turned on. The sample cup (2) of the link (21) constituting the conveyor (2)
Put the fruit on 1a). When the conveyor (2) moves, the fruits reach the bottom of the light source (5). The light emitted from the light source (5) passes through the fruit and reaches the optical cable (3). The light is transmitted to a sensor (4) connected to an optical cable. At this time, the amount of light that reaches the optical cable (3) after passing through the fruit is ensured because the light is prevented from being dispersed by the dispersion preventing cylinder (21b) installed on the link (21). With no loss of light, the light is distributed to the dispersion prevention cylinder (2
It is transmitted to the optical cable (3) adjacent to 1b). At this time, the height of the fixed plate (6) for moving the light source (5) can be adjusted according to the size of the fruit. This allows light to penetrate into the fruit and allows the light source (5) to be brought close and adjusted so that the light reaches the optical cable (3).
