Description

Technical Field

[0001] The present invention relates to the technical field of sorting equipment, and in particular to an air blowing solenoid valve actuation system, a method for calculating the number of leaked fruits, and a sorting machine. Background Art

[0002] After collecting large quantities of fruits and vegetables, large quantities of fruits and vegetables need to be sorted. During this process, the transported fruits and vegetables will be blown off the conveyor line by blowing.

[0003] However, in the prior art, there is usually a situation where the blowing action is not performed. However, when the blowing action is not performed, it is difficult for the operator to know that all the blowing actions have not been performed, and it is also difficult for the operator to judge the number of missed fruits, which will affect the sorting effect of fruits and vegetables. Summary of the invention

[0004] The technical problem solved by the present invention is how to improve the technical problem in the prior art that it is difficult to know that all the blowing actions have not been performed and it is difficult to judge the number of missed fruits.

[0005] The embodiments of the present invention can be implemented as follows:

[0010] The beneficial effects of the air blowing solenoid valve actuation system provided by the present invention compared with the prior art include:

[0011] During the process of conveying fruits and vegetables on the conveyor line, when the air blowing solenoid valve receives the blowing command, it blows air on the fruits and vegetables on the fruit cup; and the sound generated by the blowing is received by the microphone module; at this time, the microphone module that receives the sound can count once, indicating that the air blowing solenoid valve has completed a blowing action. Correspondingly, when the air blowing solenoid valve does not blow air after receiving the blowing command, the microphone module cannot receive the sound at this time, and thus no count will be generated. Therefore, the number of times the air blowing solenoid valve is actuated can be calculated by the count of the microphone module, and the number of missed fruits can be conveniently calculated. Based on this, the air blowing solenoid valve actuation system can improve the technical problems in the prior art that it is difficult to fully know when the blowing action has not been performed and it is difficult to judge the number of missed fruits.

[0016] A method for calculating the number of missed fruits is applied to the above-mentioned air blowing solenoid valve actuation system, and the method for calculating the number of missed fruits includes:

[0017] After sending the blowing instruction to the blowing solenoid valve, determining whether the microphone module receives sound;

[0018] If the microphone module receives sound, a count is added;

[0019] If the microphone module does not receive any sound, the count remains unchanged;

[0020] The number of missed fruits is calculated based on the number of blowing instructions issued and the number of counts.

[0021] The method for calculating the number of leaked fruits provided by the present invention is applied to the above-mentioned air blowing solenoid valve actuation system. The beneficial effects of the method for calculating the number of leaked fruits relative to the prior art are the same as the beneficial effects of the above-mentioned air blowing solenoid valve actuation system relative to the prior art, and will not be repeated here.

[0022] Optionally, the step of calculating the number of missing fruits according to the number of blowing instructions issued and the number of counts includes:

[0029] Control the air blowing solenoid valve to blow air;

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0043] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0044] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0045] See also Figure 1 In an embodiment of the present application, a sorting machine 10 is provided, which can be used to sort fruits and vegetables 111 to classify the fruits and vegetables 111 according to set types.

[0046] The sorting machine 10 includes a conveyor line 100 for conveying fruits and vegetables 111, and the conveyor line 100 is provided with fruit cups 110 for carrying the fruits and vegetables 111. In addition, during the sorting operation of the fruits and vegetables 111, at least some of the multiple fruit cups 110 on the conveyor line 100 are filled with fruits and vegetables 111.

[0047] In this embodiment, in order to improve the technical problem in the prior art that it is difficult to fully know and judge the number of missed fruits when the air blowing action is not performed, the sorting machine 10 also includes an air blowing solenoid valve action system 200. The air blowing solenoid valve action system 200 includes an air blowing solenoid valve 210, a microphone module 220 and a signal processing module 230. The air blowing solenoid valve 210 is arranged on one side of the conveying line 100, and is used to blow air into the fruit cup 110 according to the received air blowing instruction to blow the fruits and vegetables 111 in the fruit cup 110 off. The microphone module 220 is arranged on one side of the conveying line 100 relative to the air blowing solenoid valve 210, and is used to detect the sound generated during the air blowing process of the air blowing solenoid valve 210. The signal processing module 230 is electrically connected to the microphone module 220, and calculates and records the number of missed fruits according to the air blowing instruction and the sound received by the microphone module 220.

[0048] As described above, during the process of conveying fruits and vegetables 111 on the conveyor line 100, when the blowing solenoid valve 210 receives the blowing command, the blowing solenoid valve 210 blows air on the fruits and vegetables 111 on the fruit cup 110; and the sound generated by the blowing is received by the microphone module 220; at this time, the microphone module 220 that receives the sound can count once, indicating that the blowing solenoid valve 210 has completed a blowing action. Correspondingly, when the blowing solenoid valve 210 does not blow air after receiving the blowing command, the microphone module 220 cannot receive the sound at this time, and thus no count is generated. Therefore, the number of times the blowing solenoid valve 210 is actuated can be calculated by counting the microphone module 220, and the number of missed fruits can be conveniently calculated. Based on this, the blowing solenoid valve actuation system 200 can improve the technical problem in the prior art that it is difficult to fully know that the blowing action has not been performed and it is difficult to judge the number of missed fruits.

[0049] It should be noted that, when the air blowing solenoid valve 210 blows air to the fruits and vegetables 111, high-pressure gas is blown out from the air blowing solenoid valve 210, and a high-pressure sound is generated when the high-pressure gas flows through the fruits and vegetables 111. The microphone can receive the sound and generate a pulse signal based on the sound to send to the signal processing module 230. The signal processing module 230 can count based on the pulse signal to facilitate recording the number of times the air blowing solenoid valve 210 completes the air blowing action.

[0050] Optionally, in this embodiment, the microphone module 220 is directly opposite to the air blowing solenoid valve 210. Directly facing the microphone module 220 to the air blowing solenoid valve 210 is conducive to the microphone module 220 receiving the sound generated by the air blowing solenoid valve 210 when blowing, thereby improving the sensitivity of the air blowing solenoid valve actuation system 200.

[0051] It should be understood that in other embodiments of the present application, the microphone module 220 and the blowing solenoid valve 210 may also be arranged in a staggered manner.

[0052] In addition, in some other embodiments of the present application, the microphone module 220 can also be arranged on the same side of the conveyor line 100 as the air blowing solenoid valve 210. At this time, the microphone module 220 can not only obtain the sound generated by the contact between the air flow blown out by the air blowing solenoid valve 210 and the fruits and vegetables 111, but also obtain the sound generated when the air blowing solenoid valve 210 blows out the air flow, thereby further improving the monitoring sensitivity.

[0053] In addition, in this embodiment, the line connecting the air blowing solenoid valve 210 and the microphone module 220 is perpendicular to the conveying direction of the conveyor line 100. In this way, the distance between the air blowing solenoid valve 210 and the microphone module 220 can be minimized, so that the microphone module 220 can easily obtain the sound generated when the air blowing solenoid valve 210 blows. Of course, in the case where the air blowing solenoid valve 210 and the microphone module 220 are staggered, the line connecting the air blowing solenoid valve 210 and the microphone module 220 and the conveying direction of the conveyor line 100 can form other angles.

[0054] In this embodiment, the air blowing solenoid valve actuation system 200 further includes a detection switch 240, which is disposed on one side of the conveyor line 100 and is used to send an electrical signal for triggering an air blowing command when detecting that there are fruits and vegetables 111 on the fruit cup 110. When the fruit cup 110 containing fruits and vegetables 111 passes through the detection area of ​​the detection switch 240, the detection switch 240 detects that there are fruits and vegetables 111 in the fruit cup 110, and sends an electrical signal to trigger the air blowing command of the air blowing solenoid valve 210, thereby facilitating the efficient operation of the air blowing solenoid valve 210.

[0055] Optionally, the detection switch 240 is a photoelectric switch. Of course, the detection switch 240 can also be an infrared switch or the like.

[0056] See also Figure 2 Based on the above-mentioned air blowing solenoid valve actuation system 200 and the sorting machine 10, this embodiment also provides a method for calculating the number of missed fruits. It is worth noting that the sorting machine 10 has a control device, which is used to execute the method for calculating the number of missed fruits in this embodiment and can control the operation of other electronic components in the sorting machine 10.

[0057] The calculation method of the number of missed fruits includes:

[0058] S1. After sending a blowing instruction to the blowing solenoid valve 210, determine whether the microphone module 220 receives sound.

[0059] After sending a blowing command to the blowing solenoid valve 210, generally, the blowing solenoid valve 210 will blow air to the fruit cup 110 to facilitate the fruits and vegetables 111 in the fruit cup 110 to be blown off. However, in some cases, the blowing solenoid valve 210 will not perform a blowing action even when receiving a blowing command. However, it is precisely because the volume of the sound produced by the blowing solenoid valve 210 blowing out the gas is high and easy to collect. Therefore, the sound produced by the blowing can be used as a trigger event. When the blowing solenoid valve 210 blows, the trigger event is triggered once. At the same time, the control counter counts to facilitate knowing whether the blowing solenoid valve 210 has completed the blowing action.

[0060] S2. If the microphone module 220 receives sound, the count is incremented.

[0061] The microphone module 220 receives the sound, which indicates that the blowing solenoid valve 210 has completed the blowing action after receiving the blowing instruction, and a count can be performed at this time.

[0062] S3. If the microphone module 220 does not receive any sound, the count is maintained unchanged.

[0063] When the microphone module 220 does not receive any sound, it means that the air blowing solenoid valve 210 does not perform the air blowing action after receiving the air blowing instruction, and thus, no counting is required.

[0064] S4. Calculate the number of missing fruits based on the number of blowing instructions issued and the number of counts.

[0065] Based on this, in the method for calculating the number of missed fruits provided in this embodiment, the number of times the blowing solenoid valve 210 completes blowing is recorded by whether the microphone module 220 receives sound; however, the number of times the blowing solenoid valve 210 does not count can be calculated based on the number of blowing instructions and the number of blowing times, which is simple, clear and easy to operate.

[0066] In this embodiment, step S4 may include: subtracting the number of counts from the number of blowing instructions issued to obtain a difference, and using the difference as the number of missed fruits.

[0067] In addition, in this embodiment, after sending a blowing command to the blowing solenoid valve 210, the method for calculating the number of missing fruits further includes:

[0068] The microphone module 220 is controlled to turn on and maintain a preset time according to the blowing command. The step of judging whether the microphone module 220 receives the sound is: judging whether the microphone module 220 receives the sound within the preset time. It should be noted that since the microphone module 220 can not only receive the sound generated during the blowing process of the blowing solenoid valve 210, it is convenient to count the fruits and vegetables 111. However, the microphone module 220 can also receive the sound generated by other components. However, the sorting machine 10 as a whole has too many components that generate sound. Based on this, the microphone module 220 is controlled to turn on and maintain a preset time according to the blowing command. The problem of erroneous recording caused by the microphone module 220 receiving other sounds can be avoided, and the accuracy of recording the number of times the blowing solenoid valve 210 operates can be improved.

[0069] It should be understood that in other embodiments of the present application, the setting of the preset time may also be canceled.

[0070] Also, see Figure 3 In this embodiment, before the conveyor line 100 of the sorting machine 10 is running, the method for calculating the number of missed fruits also includes:

[0071] S11, controlling the air blowing solenoid valve 210 to blow air.

[0072] S12 , marking the sound waveform received by the microphone module 220 as a pulse event.

[0073] That is, before the fruits and vegetables 111 are transported, the blowing solenoid valve 210 is controlled to blow air so that the microphone module 220 receives the sound generated by the blowing solenoid valve 210 in advance, and the sound wave waveform of the sound generated by the blowing solenoid valve 210 can be recorded in advance to complete the recording of the pulse event, so as to facilitate the signal processing module 230 to identify whether the blowing solenoid valve 210 has completed the blowing action during the subsequent transportation process. Based on this, in the step of determining whether the microphone module 220 receives the sound, that is, in the above-mentioned step S1, if the pulse event occurs, the determination result is that the microphone module 220 receives the sound.

[0074] In summary, the blowing solenoid valve actuation system 200, the method for calculating the number of missed fruits, and the sorting machine 10 provided in this embodiment, when the conveying line 100 is conveying fruits and vegetables 111, the blowing solenoid valve 210 blows the fruits and vegetables 111 on the fruit cup 110 when receiving the blowing command; and the sound generated by the blowing is received by the microphone module 220; at this time, the microphone module 220 that receives the sound can count once, indicating that the blowing solenoid valve 210 has completed a blowing action. Correspondingly, when the blowing solenoid valve 210 does not blow after receiving the blowing command, the microphone module 220 cannot receive the sound at this time, and thus no count is generated. Therefore, the number of times the blowing solenoid valve 210 acts can be calculated by counting the microphone module 220, and the number of missed fruits can be conveniently calculated. Based on this, the blowing solenoid valve actuation system 200 can improve the technical problem in the prior art that it is difficult to fully know that the blowing action has not been performed and it is difficult to determine the number of missed fruits.

[0075] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
