[Prior art]

 Generally, conventional fruit sorters are largely classified by weight, and the method is briefly described as follows. For large fruits such as apples, pears, persimmons, peaches, etc., a weight sorter using a load cell (LOAD CELL) was used. In addition, small fruits such as citrus fruits and petit tomatoes were classified by size using a drum sorter.

[0003] However, when sorting fruits by the above-described method, various problems occur. This is summarized as follows. After harvesting the fruits, they are sorted according to size (weight), color level, and presence or absence of flaws, graded according to the value of the product, and distributed as a product, so input the time and labor required for work. Financial problems. Also, in the method of sorting fruits by grade, those that are selected by the above appearance due to the characteristics of the fruits, even if the fruits have a high grade, do not know the taste such as sugar content and acidity. It often negligently determines the value of a product, often causing the problem of degrading the value of the best product.

[0004] As a means for solving the above problems, a non-destructive fruit sorter is proposed in Korean Patent Application No. 99-35488, the general content of which is to sort fruits by grade. The light source that aggregates the transmitted light as much as possible, maximizes the optical information transmitted to the sensor, and maximizes the accuracy of the grading work, transports the fruits to the conveyor and emits light. Can be adjusted up and down, placed underneath the light source, close to the bottom dispersion prevention tank of the link that constitutes the conveyor, and the optical fiber cable connected to the sensor is positioned so that the light emitted from the light source is not dispersed outside. To provide a fruit sorter in which the fruits are sorted by grade immediately based on the measurement values that have already been input, through a fiber optic cable to the sensor. .

[0005] Furthermore, following the content of Korean Utility Model Registration No. 167516 registered on the conveyor link device attached to the non-destructive fruit sorter according to the above-mentioned Korean application, the present invention is an advanced content. During the transfer process, the light is transmitted instantaneously and effectively, forming a conveyor that is a secondary material of the sorting machine that sorts by grade.When configuring a large number of links, the link body is separated into an upper link and a lower link. This is assembled into a fixed pin and a fixed port so as to be integrated to form a double link body.

However, as a conveyor link tray of the device developed as described above, there is no method capable of dual measurement of non-destructive light sensor measurement and weight measurement, and the distribution method of fruits and vegetables is still smaller than the size in appearance. Is also more dependent on weight. The conveyor link device used in Korean Patent Application No. 99-35488 and Korean Utility Model Registration No. 16516 mentioned above also does not perform non-destructive optical sensor measurement and weight measurement at the same time. There were many problems in distribution by measuring only the size of fruit and fruit.

[0007]

[Problems to be solved by the invention]

 The purpose of the present invention is to provide a conveyor link body capable of simultaneously measuring a non-destructive optical sensor and measuring a weight. In order to achieve the above purpose, light is transmitted through the fruit instantaneously during the process of transferring the fruit by the conveyor, the taste is measured by a non-destructive light sensor, and then the present invention is applied to a load cell (LOAD CELL). By developing a conveyor link device that can measure the weight of fruits while passing through the link body and measure the taste and weight at the same time, the link body can be used to construct a large number of links that form a conveyor connected to the above link body. The fixing projection of the upper link, which forms the link, is inserted into the fixing opening of the lower link and fixed, thereby completing a single link body and fixing it to bolts, providing sufficient impact mitigation, noise prevention, durability, etc. In consideration of the above, the O-ring and the rubber packing are to be attached.

[0010] As shown in the figure, FIG. 1 schematically illustrates the sorter used in the present invention, which is installed on an upper stage of a conveyor to measure fruit taste information. As the light investigated from several light sources travels on the conveyor, optical information is finally transmitted to the non-destructive optical sensor through the guidance of the fiber optic cable attached to the bottom of the conveyor through the fruits. The transmitted optical information is instantaneously calculated as taste information according to the absorbance value of the fruit, and is classified according to grade. Then, in order to measure the weight information of the fruit, the weight of the fruit that has passed through the nondestructive light sensor is measured while passing through the site where the load cell (LOAD CELL) is located.

The present invention relates to a conveyor link body that can simultaneously measure the weight of a link body 16 that measures the taste of fruits by grade. The link body 16 is separated into an upper link 10 and a lower link 11. . The upper link 10 is configured so that fruits can be mounted thereon. Here, the load cell 27 measures the weight of each empty link having no fruit mounted thereon, and the main control PC 25 stores the weight. When the fruit is mounted, the weight is calculated by removing the weight of the empty link. Is measured by the load cell 27 to classify the class.

In the above, two load cells 27 are provided, one on each side of the link passing over the guide rail 23, and one pair is formed. The signals of the two load cells 27 are transmitted to the indicator 24 through the cable 32. Will be transferred. At this time, the indicator 24 simultaneously reads the values of the two load cells 27 and transfers the final value to the main control PC 25.

According to the present invention, the upper link 10 and the lower link 11 are constituted by the upper link 10 and the lower link 11 at the time of the above-mentioned weight measurement. Then, the left and right guides come into contact with and pass over the load cell 27, and at this time, the upper link 10 is separated from the lower link 11.

FIG. 2 is a perspective view of the present invention, in which a fixing projection 12 attached to the upper link 10 is inserted into a fixing opening 13 formed in the lower link 11 to form one link body 16 and a bolt 35 The O-ring 36 and the rubber packing 37 are adhered to serve to buffer the gasket from being fixed.

FIG. 3 is an exploded perspective view of the present invention, in which an insertion portion 18 is formed on the surface of the upper link 10, and several fixing projections 12 are fixed on the lower surface of the upper link 10. Have been. One transmission hole 39 and several fixing holes 13 are formed on the surface of the lower link 11, and a fixing member 17 is formed integrally with the reinforcing core 14 on one side of the lower surface thereof.

Each fixing hole 17 is formed in the fixing member 17, and a fixing pin 21 is inserted into the fixing hole 15 so that a fixing member 17 ′ can be formed on a support portion 40 connected to the sorting machine. It is. At this time, the above-mentioned fixing member 17 'is composed of a large number and is firmly bound to the support portion 40. Therefore, a separate operation lever 38 is fixed to the support portion 40 so that the link body 16 can be rotated. It is fixed to a pin 21.

FIG. 4 is a partial cross-sectional view of the link body, which is a main part of the present invention. The upper link 10 has a support projection 19 and a transmission hole 39 formed on the surface thereof. The fixing projection 12 formed on the lower surface is inserted into a fixing hole 13 formed on the lower link 11, and is fixed to the O-ring 36 and the bolt 35.

The conveyor chain 22 is formed integrally with the supporting portion 40, and the operating lever 38 is fixed to the supporting portion 40 by the fixing pin 21 inserted into the fixing member 17 '. Further, a portion 20 of the support portion 40 on which the operating lever 38 is hooked is fixed to a fixing pin 21 fixed to the lower link 11, so that the fruit can be moved from a state where the fruit is put on the input portion 18.

FIG. 5 is a side view showing a state in which the link main body, which is a main part of the present invention, is operated. The main body 16 can drop the fruit freely while tilting to one side. At this time, a slight impact is generated on the upper link 10 and the lower link 11 which are separated while the link body 16 is falling, but the impact is absorbed by the rubber packing 37 and the O-shaped ring 36. After preparing several link bodies 16 assembled as described above, the conveyor chain 22 and the guide rail 23 attached to one side surface of the support portion 40 are interconnected and driven.

The operation of the present invention configured as above will be described in detail as follows. When power is supplied to the above-mentioned sorting machine, the conveyor chain 22 is transferred, and a plurality of light sources are used from the upper stage of the guide rail 23, and the optical information transmitted through the fruit is attached to the lower stage of the link body 16 using an optical fiber cable 32. With the guidance, fruits can be sorted by taste by inputting with a near-infrared sensor.

As described above, the link main body 16 is configured as a double multiple link device in which the upper link 10 and the lower link 11 are integrated, and the rubber packing 37 is provided on the upper side to reduce the shock generated by the rotation of the link main body 16. Attach to each corner where link 10 and lower link 11 are in close contact.

Further, since the fixing protrusion 12 of the upper link is inserted into the fixing opening 13 of the lower link 11, when the link rotates, a force is generated to separate the upper link 10 from the lower link 11, thereby preventing the force. Therefore, the bolt 35 is fastened to the fixing protrusion 12.

In the above situation, the O-ring 36 is inserted into the fixing projection 12, so that the impact of the lower link 11 can be reduced. Therefore, it is appropriate that the load cells 27 formed on one side of the guide rail 23 are installed on the left and right sides in the traveling direction of the conveyor so that the link body 16 on which fruits are placed through the guide rail 23 advances. become.

At this time, the load cell 27 quickly measures the weight of only the fruit excluding the weight of the link body 16 during the movement, and sends a signal with the indicator 24. The indicator 24 receives this signal and transmits the weight value of the fruit to the main control PC 25.

The link body 16 on which the fruits passing through the load cell 27 are placed secondly passes through the non-destructive optical sensor measuring unit 26. At this time, the internal quality components are measured and measured. The optical data is transferred to the main control PC 25. Then, the main control PC 25 uses the weight value of the fruit received from the indicator 24, the sugar content and the value received from the non-destructive sensor, calculates the grade, and finally generates a signal that can be classified by the grade. It is transmitted to the solenoid valve and classified.

As described above, when the sorting based on the sugar content of the fruit is completed, the above-mentioned device which transmits light passes through the above-mentioned device, and the above-mentioned operation is performed by operating the operating lever 38 which is connected to the fixing member 17 formed on one side of the link body 16 by a pin. While the link body 16 is facing downward, the fruits are stored in storage boxes separated by grade, and when the fruits are detached from the link, the fruits put in the sample cup 2 are formed in the input portion 18 of the sample cup 2. This is very convenient because the perforations do not create a vacuum and automatically fall when the link goes down. Therefore, while providing the link composed of the conveyor of the fruit sorter as described above, it is linked with the method of simultaneously measuring the weight and internal quality of the fruit with an optical sensor, and the classification of the fruit by the grade is accurately made. This is a very practical device that can standardize the class.
