[0002] The flexible fruit and vegetable sorting equipment is a sorting equipment that combines intelligent technology and the concept of flexible production. It can accurately classify fruits and vegetables according to their different characteristics, thereby improving the quality and consistency of fruits and vegetables and enhancing production efficiency. It is usually composed of a conveyor belt and a transfer conveyor tray. The conveyor belt is used to transport fruits and vegetables or fruit trays and is the basic part of the equipment. There are multiple conveying grooves arranged outside the transfer conveyor tray, and the conveying grooves match the sizes of fruits and vegetables or fruit trays and are used to transfer fruits and vegetables or fruit trays one by one. In the existing flexible fruit and vegetable sorting equipment, when transporting the fruit trays, it is impossible to accurately position the fruit trays transported to the chain plate, resulting in too large or too small spacing between fruits and vegetables or fruit trays during transportation. When the fruits and vegetables or fruit trays are transported to the transfer conveyor tray, the fruits and vegetables or fruit trays cannot be accurately positioned into the conveying grooves outside the transfer conveyor tray, causing jamming phenomena, which in turn affects the normal operation of the equipment and causes delays in fruit sorting.

[0049] When the baffle positioning station 24 is used to convey the fruit tray 201 into the indexing plate material transfer and transfer assembly 2, it cooperates with the indexing plate 21 to position and convey the fruit tray 201;

[0050] Arc-shaped positioning slots 211 are evenly distributed on the outer circumferential surface of the indexing plate 21, and the size of the arc-shaped positioning slots 211 matches that of the fruit tray 201;

[0054] A positioning and sorting device for a fruit flexible sorting line provided by the present utility model has the following operating principle and operating process:

[0055] S1: This positioning and sorting device for a fruit flexible sorting line is divided into two parts: namely, a sorting and conveying component 1 and an indexing plate material transfer and transfer component 2; wherein, the sorting and conveying component is composed of a mounting frame 10 and a feeding and conveying device 20 arranged on the mounting frame 10, and the feeding and conveying device 20 is composed of a feeding conveyor belt 11, a waiting conveyor belt 12 and a plurality of differential conveyor belts 13 arranged in sequence from back to front; the indexing plate material transfer and transfer component 2 includes an indexing plate 21, a guiding member 22 and a transmission component 23;

[0056] S2: The fruit tray 201 is continuously conveyed by the circulation line of the fruit flexible sorting line to the feeding conveyor belt 11 on the sorting and conveying component 1, and the feeding conveyor belt 11 conveys the continuous fruit trays to the waiting conveyor belt 12. A fruit tray stop device 15 and a photoelectric sensor 16 are respectively arranged at the left end and the right end of the waiting conveyor belt 12. The fruit tray stop device 15 includes a pushing cylinder 151 and a pushing baffle 152 installed at the output end of the pushing cylinder 151. Among them, the pushing cylinder 151 and the photoelectric sensor 16 can also be controlled to operate through an existing control system;

[0057] When the fruit tray 201 reaches the detection range of the photoelectric sensor 16, the pushing cylinder 151 immediately drives the pushing baffle 152 to extend out to block the fruit tray 201, and the detection baffle positioning station 24 reaches the specified position (i.e., the position convenient for the transmission of the fruit tray 201).

[0058] At this time, the photoelectric sensor 16 monitors in real time whether the distance between the passing fruit trays 201 is within the error range. If it is within the error range, it enters step 3;

[0060] S4: After a certain period of time, when the fruit tray 201 is about to reach the indexing plate 21, the arc-shaped positioning slot 211 on the rotating indexing plate 21 just meets the fruit tray 201. After accurately entering the arc-shaped positioning slot 211, the rotating indexing plate 21 drives the fruit tray to move and transfer. At this time, the fruit tray 201 also successfully enters the baffle positioning station 24; at this time, the guide member 22 is used for guiding to prevent the fruit tray 201 from being thrown out by the centrifugal force of the rotating indexing plate 21;

[0061] S5: The rotating indexing plate 21 drives the fruit tray 201 to move and transfer;

[0062] S6: When the fruit tray is continuously conveyed to the sorting and feeding component 1 and the indexing plate material transfer component 2 by the circulating line of the fruit flexible sorting line, when the photoelectric sensor 16 monitors in real time that the distance between some fruit trays 201 is greater than the error range, the pushing cylinder 151 extends out to block the fruit tray 201 for adjustment.

[0063] The utility model provides a positioning and sorting device for a fruit flexible sorting line, which can monitor the distance between adjacent two fruit trays in real time through a photoelectric sensor, so that the fruit tray can smoothly enter the arc-shaped positioning slot, avoid jamming phenomenon, ensure the normal operation of the equipment, and ensure the normal progress of fruit sorting.
