a weighing device 40 for weighing the fruit;
the upper computer 43 superimposes and splices the peripheral photos, the bottom photos and the top photos of the fruits to analyze the appearance quality of the fruits, classifies the fruits into a plurality of grades according to the quality of the fruits, and sends commands to the sorting cylinders 47 at the sorting channels 35 according to the grades, the appearance quality and the internal quality of the fruits to dial the fruits into the sorting channels 35 of different grades.
The fruit sorting and boxing method provided by the embodiment of the invention comprises the following steps of:
s1, placing fruits on a tray 18 on a first tray conveying channel 32; the tray 18 photographs the periphery and the bottom of the fruits through the first appearance detection device 4 on the production line;
s2, the fruits are subjected to top photographing through top photographing equipment 46 on the production line;
s3, monitoring the internal quality of the fruits through a spectrum analyzer 39 on the production line;
s4, the fruits pass through a weighing device 40 on the production line to weigh the fruits;
s5, the upper computer 43 sorts out qualified fruits and unqualified fruits; internal quality qualified fruits and internal quality unqualified fruits; dividing the fruits into a plurality of grades and unqualified fruits according to the quality of the fruits;
s6, the upper computer 43 sends commands to the sorting cylinders 47 of the sorting channels 35; pulling unqualified appearance fruit, unqualified internal quality fruit, and unqualified quality fruit into culling channel 355; the fruits with different grades are respectively poked into the sorting channels 35 with corresponding grades;
s7, the upper computer 43 calculates the weight of the fruits in each grade channel, and after the set boxing weight is reached, a release mechanism at the bottom of the corresponding sorting channel 35 is opened to release the fruits in one sorting channel 35 to the release channel 36;
s8, conveying fruits to a boxing channel through a release channel 36; the boxing lane divides the fruit into three lanes for transport to three different boxing stations 38 for layered boxing.
At least two sorting channels 35 are arranged on the fruits of the same grade, and the quality tolerance of the fruits of each grade is 100g; the upper computer 43 distributes the same grade fruit to different sorting channels 35 according to the set boxing quality, so as to ensure the quality uniformity of each fruit box. Specifically, in this embodiment, the fruits are classified into a class a, a class B, a class C and a class D according to weight, and the fruits with too light weight are judged as unqualified fruits and are rejected through the reject channel 355; the unqualified appearance fruits and the unqualified internal quality products are directly rejected through the reject channel 355, and the unqualified appearance fruits and the unqualified internal quality fruits are assigned grades according to weight.
When the tray passes through each detection station, the code is scanned and recorded by the code scanner, and then the bar code and the detection result are bound and sent to the upper computer 43; because at least two sorting channels 35 are arranged on each grade of fruits, for example, three grade A channels 351 are allocated to grade A fruits, 46-48 fruits are required to be layered in each box, the total weight is about 25kg, each grade A fruit is 0.5-0.6kg, if 46 fruits are already in one grade A channel 351, and the total mass of 46 fruits is 24.5kg, the upper computer 43 sends an instruction to the sorting cylinder 47 at the sorting channel 35, allocates 0.5kg of fruits to the grade A channel 351, and allocates other qualities of fruits to the grade A channel 351 which is temporarily less than 25 kg; when the quality of the A-level channel 351 meets 25kg, a blocking cylinder at the lower end of the A-level channel 351 is opened to enable fruits to be conveyed to the fruit conveying channel 36, the fruit conveying channel 36 distributes 47 fruits to three layered boxing channels 37, 16 fruits are distributed on the lower layer boxing channel and the middle layer boxing channel respectively, 15 fruits are distributed on the upper layer boxing channel, the fruits are conveyed to the boxing platform 38, layered boxing is completed through a manipulator near the boxing platform 38, and after boxing is completed, all empty trays 18 are conveyed to the first tray conveying channel 32 and conveyed back to the second conveying chain 3.
According to the invention, fruits with relatively fragile surfaces can be effectively protected by placing the fruits on the tray 18, the tray 18 can be automatically recycled through the first tray conveying channel 32, 360-degree photographing detection of the appearance of the fruits can be realized, unqualified fruits are removed from the aspects of appearance quality, internal quality and quality of the fruits, products are classified into different grades, and the quality difference of boxing of the fruits at the same grade can be as small as possible. The automatic sorting and automatic boxing are completed in the whole process, the detection and boxing efficiency is high, the human interference is small, and the sorting and boxing efficiency is greatly improved.
It should be understood that the above-described specific embodiments are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications which extend from the spirit of the present invention are within the scope of the present invention.
