Abstract

(57) [Abstract] [Purpose] The present invention aims to improve operation efficiency by appropriately handling fruits having different diameters in a conveyor belt for spherical fruits and the like. [Structure] A sorting conveyor 1 for placing and transferring a single fruit, in which large-diameter fruit placement position designation marks 15, 15 ... Are provided at a constant interval pitch P ₁ in the transfer direction, and at a pitch P ₂ different from this interval. Placement mark 16,1 for small fruit
By providing 6 ..., these can be easily distinguished and the fruit placement work can be performed stably.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a conveyor for selecting fruits and vegetables.

[0002]

[Prior Art]

 For example, there is a demand to sort and sort pumpkins by size at fruit-pickling facilities, and at the same time, to sort watermelons according to size. There is a demand to improve the operation efficiency of the equipment by properly using these two depending on the production area.

[0003]

[Problems to be solved by the device]

 However, in the past, the sorting conveyor was provided for each fruit and had the characteristics of a dedicated machine. For this reason, it has poor versatility despite the common structure of the detection unit.

[0004]

[Means for Solving the Problems]

For this reason, the present invention is a sorting conveyor 1 for transferring a single fruit to be transferred, and the large-sized fruit mounting position designation marks 15, 15 ... Are provided at a constant interval pitch P ₁ in the transfer direction, which is different from this interval. It is configured as a conveyor for selecting fruits and vegetables, etc., which is provided with the mounting position designation marks 16, 16 for small fruits at the pitch P ₂ .

【Example】

 An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 is a sorting conveyor in the form of a belt conveyor, which is wound between the front and rear driving rollers 2 and driven rollers 3. A certain section of the conveying start end side of the sorting conveyor 1 serves as a sorting result, for example, a hand rest portion 4 on which pumpkin or watermelon is placed, and a detection sorting portion 5 for sorting and discharging according to a predetermined size from the middle portion to the end portion. .

The detection sorting section 5 is provided so that it can be sorted into six classes in the traveling direction of the conveyor and can be taken out to the receiving box sections 5a, 5a ..., Each of which is provided with a class detection section 6,6. The detecting units 6, 6 ... Are known methods by which the height of the fruits to be sorted and the length along the traveling direction can be measured with a photoelectric tube. That is, the photoelectric tube comprises an existence / non-existence detecting section 8, a traveling direction length detecting section 9 and a height direction detecting section 10 for recognizing the passage of the objects to be sorted.

Reference numeral 11 is a determination unit that determines whether or not to discharge at the sorting position based on the information from the class detection unit 6. Reference numeral 12 is a discharge signal from the determination unit 11, and operates the air cylinder mechanism 13 to interlock. Is a mechanism for swinging the discharge arm 14 of FIG. The screened on the surface side of the conveyor 1, the mark large diameter fruits for watermelon sorting 15, 15 for each pitch P _1, the small diameter of the short pitch P ₂ every pumpkin or melon selection for another the pitch P ₁ The fruit marks 16, 16 ... Are attached in a form that allows easy visual recognition, such as color-coding and circular marks of different diameters.

The operation of the above example will be described. The watermelons are picked up one by one from a container (not shown) near the hand placing section 4 and placed on the marks 15, 15 ... of the sorting conveyor 1 in sequence. In the class detection unit 6, the diameter of the fruit is sequentially set from the upper side to the larger one, and then the diameter is gradually set to the smaller one to determine the preset class in combination with the photocell and the operation of the discharge mechanism in the relevant class section. Is discharged and dropped by.

Next, when the pumpkin is selected, it is possible to perform the same selection by placing it on the mark 16, 16 ... side. In this case, however, the position of the photoelectric tube is changed and set to reduce the diameter. It is advisable to provide it so that it can be dealt with. FIG. 6 shows another embodiment of the marks 15 and 16, in which a circular or rectangular concave portion is formed on the belt conveyor itself (the same (a)) to ensure stable conveyance of fruits, and a combination of these or a circular diameter. Alternatively, one side of the rectangle may be different to accommodate large and small fruits. Further, the circular concave portion may be replaced with a fine rough surface finish (same as (c)) or a buffer projection may be partially provided (same (c)).

[Function and effect of the device]

 Depending on the size of the fruits to be placed on the sorting conveyor 1, one of the marks attached on the sorting conveyor 1 can be selected and placed by hand one by one. The objects to be sorted can be set accurately at regular intervals, and the grade can be set. It is possible to perform sorting work that matches the capabilities of the sorting unit and the discharging mechanism, thus improving work efficiency.
