Technical Field

[0001] The present invention belongs to the technical field of fruit conveying and sorting, and specifically belongs to an anti-fruit cup dropping detection system for a fruit and vegetable sorting device. Background Art

[0002] Currently, in order to improve the economic value of fruits, after the fruits are harvested, they often need to be weighed and sorted and packaged according to conditions such as size, sweetness, and appearance quality, and then sold in the market. Moreover, the original data of the fruits will be collected accordingly, so as to facilitate subsequent tracking and verification of the fruits.

[0003] At present, for the single-piece transmission of some fruits, generally, an appropriate fruit cup is used for carrying and conveying, and weighing and sorting are carried out. That is, in a fruit and vegetable sorting device, through a driving wheel, a driven wheel, a transmission chain, and a fruit cup installed on the transmission chain, the fruit cup is used to carry fruits and vegetables for detection and sorting. However, currently, due to the limitations of the existing fruit and vegetable sorting device itself, during the process of the fruit cup being transmitted between the driving wheel and the driven wheel along with the transmission chain, the fruit cup is likely to fall off in large quantities due to collision at the driving wheel or the driven wheel. Moreover, if this problem is not discovered and the machine is not stopped in time, it will cause serious damage to the fruit and vegetable sorting device. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an anti-fruit cup dropping detection system for a fruit and vegetable sorting device. This system aims to solve the technical problems that in the existing fruit and vegetable sorting device, the fruit cup is likely to fall off in large quantities due to collision at the driving wheel or the driven wheel, and if it is not discovered and the machine is not stopped in time, it will cause serious damage to the fruit and vegetable sorting device. This system can quickly and efficiently identify the problem of fruit cup dropping during the operation of the fruit and vegetable sorting device, automatically and timely shut down the fruit and vegetable sorting device, and output an alarm prompt, so as to avoid more serious damage to the fruit and vegetable sorting device and extend the service life of the fruit and vegetable sorting device.

[0006] (2) Technical Solutions

[0007] To solve the above technical problems, the present invention provides such an anti-fruit cup dropping detection system for a fruit and vegetable sorting device. This system includes a first detection grating installed below the driving wheel of the fruit and vegetable sorting device for detecting the dropping of the fruit cup at the driving wheel, a second detection grating installed below the driven wheel of the fruit and vegetable sorting device for detecting the dropping of the fruit cup at the driven wheel, a timer for timing, a counter for counting, and a controller for collecting information, analyzing, and automatically controlling feedback. The first detection grating, the second detection grating, the timer, and the counter are respectively electrically connected to the controller.

[0008] Preferably, the first detection grating and the second detection grating are infrared detection sensors.

[0009] Preferably, the controller is an automatic PLC (Programmable Logic Controller, simply referred to as PLC, programmable logic controller) controller.

[0010] Preferably, the threshold for the first detection grating or the second detection grating to output an alarm prompt is to be continuously triggered more than 3 times within 1 s.

[0011] Preferably, the threshold for the first detection grating or the second detection grating to output an alarm prompt is that the first detection grating or the second detection grating is continuously triggered for more than 1 s.

[0012] Working principle: During the operation of the fruit and vegetable sorting equipment, when the fruit cup drops due to collision at the driving wheel or the driven wheel, the first detection grating or the second detection grating below the driving wheel or the driven wheel will be triggered. At the same time, the timer and the counter time and count the detection results of the first detection grating and the second detection grating. Moreover, the first detection grating, the second detection grating, the timer and the counter will also transmit the detected data information to the controller. The controller collects this information and analyzes it, and automatically shuts down the fruit and vegetable sorting equipment through the preset threshold value and triggers an alarm prompt. For example, when it is set that the first detection grating or the second detection grating is continuously triggered more than 3 times within 1 s, or when the first detection grating or the second detection grating is continuously triggered for more than 1 s (this threshold value can be set corresponding values according to different varieties of sorted fruits), the controller determines that a large number of fruit cup dropping problems have occurred, thus automatically shutting down the fruit and vegetable sorting equipment and outputting an alarm prompt.

Obviously, the described detailed implementation manners are only a part of the implementation manners of the present invention, rather than all the styles.

[0019] Embodiment 1

[0020] This detailed implementation manner is a detection system for preventing fruit cups from falling for fruit and vegetable sorting equipment. The system includes a first detection grating 2a installed below the driving wheel 1a of the fruit and vegetable sorting equipment 1 for detecting the falling of the fruit cup 1d at the driving wheel 1a, a second detection grating 2b installed below the driven wheel 1b of the fruit and vegetable sorting equipment 1 for detecting the falling of the fruit cup 1d at the driven wheel 1b, a timer 3 for timing, a counter 4 for counting, and an automatic PLC controller 5 for collecting information, analyzing and automatically controlling feedback. The first detection grating 2a, the second detection grating 2b, the timer 3 and the counter 4 are respectively electrically connected to the automatic PLC controller 5; wherein, both the first detection grating 2a and the second detection grating 2b use infrared detection sensors.

[0021] During the operation of the fruit and vegetable sorting equipment 1 and through this detection system for preventing the fruit cup 1d from falling, when the fruit cup 1d falls due to collision at the driving wheel 1a or the driven wheel 1b, the first detection grating 2a or the second detection grating 2b below the driving wheel 1a or the driven wheel 1b will be triggered.
