Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a fruit sorting machine for classifying fruits having a sugar content such as peaches and ε-kan according to size.

(Prior Art) Such fruit sorting machines include those configured to classify and sort fruits according to their size, and those configured to classify and sort fruits by simultaneously detecting size and quality.

(Problem to be solved by the invention) In general, size and sugar content (sweetness) are the main requirements for people to buy fruits.

However, in the conventional structure, the classification is based only on size and quality, so even though the fruit is large and does not spoil, it may have insufficient sugar content, that is, it may be tasteless.

(Means for Solving the Problems) The present invention solves the above technical problems and takes the following technical measures.

In other words, the - of Conhair (2) that moves with fruit (1) on it
A supply section (3) for feeding fruits onto the conveyor (2) is installed on the side, and a classifying section (4) for classifying the fruits (1) according to size is installed on the other side. Supply section (3)
A fruit sensor (5) for detecting the size of the fruit (1) and a sugar content sensor (6) for detecting the sugar content of the fruit (1) are installed between the fruit sensor (5) and the classification unit (4). The fruit sorting machine is configured to include a determining device (7) that receives a determination signal from a sugar content sensor (6) and determines the grade of fruit based on this signal.

(Function) Fruits (
The fruit (1) is transported by this conveyor (2) towards the machine side, or the size of the fruit (1) is detected by the fruit sensor (5) at the time of transport, and the fruit (1) is transported by the sugar content sensor (6). sugar content is detected. Then, the determiner (
7) or both sensors (5) and (6) to judge the grade of the fruit (1).

(Effects) Since the fruit (1) can be classified according to size, and the sugar content can be determined at the same time, the commercial value of the fruit (1) can be increased.

(Example) Hereinafter, an example of the present invention will be specifically described based on the drawings.

First, to explain its structure, the fruit sorting machine (8) is composed of a conveyor (2), a sorting section (4), etc., and this conveyor (2) is rotatably attached to both the front and rear ends of the frame (9). A pair of left and right ring bodies θ]) (one of which is not shown) and a pair of left and right endless belts (one of which is not shown) wrapped and stretched between the ring body Qoj (11). (1
), and a large number of fruit-placing plates (one sword is arranged) rotatably pivoted between the endless belt 0 and arranged at predetermined intervals in the direction of movement, and the fruit-placing plates 0 The Enoki is configured so that when it reaches a predetermined classification position, it is tipped over by a classification device (for example, Tsureid).

In addition, the above-mentioned transport body (ICI) is a pulley (hill) fixed to the end of the shaft (14), and a boo' fixed to the end of the motor shaft (0.7) of the motor (+6). -C is transmitted through the installed heel l-(1,!a) and rotates in the direction of the arrow LN.

The classification section (4) is installed on the - side of the conveyor (2), and is arranged from the downstream side in the moving direction of the conveyor (2) to S, M, 1
・, 2L class +1 [located in J. And, within each class, the sugar content is below the set value (A) and above the set value (03)
The cage is divided into two parts, and each cage is provided with the classification device (4).

Detection case 121) is Conhair (2) fruit R plate (]■
・It forms a passage through which the fruits (1) moving are allowed to pass, and is also formed in a concave shape. The case (2) includes a fruit sensor (5) that detects the size of the fruit (1) from the lower side in the direction of movement of the container (2), and a fruit sensor (5) that detects the size of the fruit (1)
) are sequentially equipped with sugar content sensors (6) for detecting the sugar content of the fruits. Alternatively, the sugar content sensor (6) is limited to one that detects the sugar content using ultrasonic waves. good.

The unclassifiable case (a) is installed between the classification section (4) and the detection case (21), and each sensor (5) (6)
When either the size or the sugar content cannot be detected, the four pieces transported to the classification section (4) are discharged to the outside of the conveyor (2) by the classification device (a). (stomach)
is an unclassifiable conveyor that conveys the unclassifiable fruits discharged outside the conveyor (2) again to the supply section (3) side of the conveyor (2).

To explain the block circuit in Fig. 3, the company is a shape judger, which receives the signal from the fruit sensor (5).
The configuration is such that the size of the shape is determined by comparing the signal with a reference value set by a preset shape reference setting device (a). (A) is a sugar content determination device which receives a signal from the sugar content sensor (6) and compares the signal with a preset reference value set by a first sugar content standard setting device to determine the sugar content. It is configured to determine height. Judgment device (7)
receives the judgment signals from the shape judger and the sugar content judger (20), judges the grade of the fruit (1) based on these signals, and sends a classification command signal to the classification device (a) at a predetermined classification position. It is connected to the shift register (c) which sends the signal.

Next, to explain its effect, the fruit (1) supplied from the supply section (3) to the fruit tray q■hi is transferred to the conveyor (
In conjunction with the movement in step 2), it moves toward the classifying section (4). 7. At this moving speed, the fruit sensor (5)
Then, the size is detected using the l: sensor, and then the sugar content sensor (
6) The sugar content is detected by J2. And each sensor (
5) The judgment signal in (6) is sent to the shape judger (2) and the sugar content judger (2+), where it is compared with a preset reference value, and then the judger (7) comprehensively evaluates the fruit. The size and sugar content of (1) are determined, and the sample is discharged to a predetermined classification position via shift 1/register (c). Now, for example, if this fruit (1) is in grade 4 and the sugar content is above the standard value, the classification device (a) on the 13 side of grade M will operate to overturn the fruit tray A, and the fruit ( ]) on the 13th side Kate (fruit collection department)
Exclude? , = S, If foreign matter gets mixed in with the fruit and the detection function of each sensor (5) (6) becomes impossible,
The fruit tray 0 is overturned by the classification section M (a) of unclassifiable case 1 (c) and is discharged to the conveyor (2) side.

Then, this fruit is conveyed to an unclassifiable conveyor and sent again to the supply section (3) of the conveyor (2).

In this example, the size of the fruit (1) was detected by sorting the fruit (1) by shape, but it is of course possible to classify the fruit (1) by size based on weight.
