Description

Technical Field

[0001] The present invention relates to the technical field of fruit sorting, and in particular to a fruit sorting device and method. Background Art

[0002] Fruit sorting devices are widely used in the field of fruit sorting. Fruit cups are fixed on a conveying mechanism, and the conveying mechanism drives the fruit cups to pass through different detection units in sequence to detect the visual, weighing, and internal quality data of the fruit. Since the detection units are arranged on the conveying mechanism in sequence, multiple fruit cups pass through multiple detection units in sequence under the drive of the conveying mechanism. After detecting the data, the detection unit transmits it to the control unit, and the control unit finally integrates it. For a single detection unit, the data of multiple fruit cups will be detected. In order to be able to identify the data of different fruit cups, barcodes are usually attached to the fruit cups, and the data is integrated by scanning the barcodes to achieve multiple sorting. However, this method is cumbersome to operate, and if the fruit cup is lost between two detection units, it will cause confusion in the data integration of the subsequent detection units. In other words, the current fruit sorting device is prone to data confusion in the process of sorting fruits, resulting in poor final sorting accuracy. Summary of the invention

[0003] The object of the present invention is to provide a fruit sorting device and method, which can match multiple detection information with the fruit cup after receiving the detection information of the fruit cup detected by the detection unit, so as to minimize the problem of confusion in subsequent data, thereby improving the accuracy of fruit sorting.

[0004] The embodiments of the present invention can be implemented as follows:

[0005] In a first aspect, an embodiment of the present invention provides a fruit sorting device for sorting fruits, the fruit sorting device comprising: a control unit, a transmission component, a detection component, a fruit cup, a plurality of fixing components and a plurality of detection units;

[0006] The fruit cup is used to hold fruit;

[0007] The fixing assembly is used to fix the fruit cup;

[0008] The detection component is arranged at the input end of the transmission component, and the detection component is connected to the control unit, and is used to detect the arrival signal of the fixed component moving to the input end, and send the arrival signal carrying the starting time to the control unit;

[0009] The plurality of fixing components are sequentially mounted on the conveying component, and driven by the conveying component to sequentially drive the plurality of fruit cups to pass through the plurality of detection units;

[0010] A plurality of the detection units are connected to the control unit. The detection units are configured to collect detection information of the fruit cup once every preset time interval, and send the detection information carrying time information to the control unit;

[0011] The control unit is configured to be connected to the detection units and the detection components, and is configured to receive a plurality of the detection information, and match the detection information corresponding to the fruit cup of the in-place signal according to the running speed of the conveying component, the starting time of the in-place signal, the distance between the detection unit and the detection component, and the time information of the detection information.

[0012] In the embodiment of the present invention, fruits are placed in the fruit cups, and the fruit cups are fixed on the fixing components. Under the action of the conveying component, the fixing components drive the fruit cups to sequentially pass through a plurality of detection units arranged in the extending direction of the conveying component. The input end where the fruit cup is placed on the fixing component can be regarded as the starting position of the movement of the fruit cup on the conveying component. Obtaining the in-place signal when the fixing component moves to the input end can be regarded as obtaining the starting time when the fixing component drives the fruit cup on the conveying component. According to the starting time, the running speed, and the distance between the detection unit and the detection component, the detection information corresponding to the fruit cup of the in-place signal detected at the detection unit can be matched. In the embodiment of the present invention, according to the starting time, the running speed, the distance between the detection unit and the detection component, and the time information, the matching between the fruit cup and the detection information can be realized, the one-to-one correspondence between a plurality of detection information and a plurality of fruit cups can be realized, the influence of fruit cup loss on subsequent sorting can be avoided, and the problem of subsequent data disorder can be reduced as much as possible, thereby improving the accuracy of fruit sorting.

[0013] In an optional embodiment of the present invention, the control unit is further configured to calculate the movement time for the fixing component to drive the fruit cup to move from the detection component to the detection unit according to the running speed and the distance between the detection unit and the detection component, and calculate the end time for the fixing component to move to the detection unit according to the starting time of the in-place signal and the movement time, and match the detection information with the same time information as the end time.

[0014] In the embodiment of the present invention, according to the starting time, the running speed, the distance between the detection unit and the detection component, and the time information, the matching between the fruit cup and the detection information can be realized, the one-to-one correspondence between a plurality of detection information and a plurality of fruit cups can be realized, the influence of fruit cup loss on subsequent sorting can be avoided, and the problem of subsequent data disorder can be reduced as much as possible, thereby improving the accuracy of fruit sorting.

[0015] In an alternative embodiment of the present invention, if there is detection information among the multiple pieces of detection information that matches the end time, the detection information is recorded into the detection data of the fruit cup corresponding to the in-place signal.

[0016] The detection unit collects a piece of detection information after every preset time interval and sends the detection information carrying time information to the control unit. The control unit then matches the detection information with the same end time among the multiple pieces of detection information. If there is detection information that is the same as the end time, then this detection information is the detection data of this fruit cup, and this detection information is recorded into the detection data of this fruit cup.

[0017] In an alternative embodiment of the present invention, if there is no detection information among the multiple pieces of detection information that matches the end time, the detection data of the fruit cup corresponding to the in-place signal is discarded.

[0018] If there is no detection information that matches the end time among the multiple pieces of detection information, it may be that the fruit cup is lost during the movement to the detection unit, or the fruit cup is not lost, but the detection unit does not detect the detection information of this fruit cup. This indicates that there is no detection information of this fruit cup among the multiple pieces of detection information, so the detection data of this fruit cup is discarded and the next sorting work is not carried out.

[0019] In an alternative embodiment of the present invention, the conveying assembly includes a transmission chain and a driving wheel. The transmission chain is in transmission connection with the driving wheel, and multiple fixing assemblies are sequentially installed on the transmission chain.

[0020] The multiple fixing assemblies are evenly spaced and installed on the transmission chain. Driven by the driving wheel, the transmission chain can drive the fruit cups fixed on the fixing assemblies to sequentially pass through multiple detection units. The transmission in the way of the driving wheel and the transmission chain can increase the stability of the conveying assembly during the transmission process and reduce the problem of slipping that occurs in the conveying assembly during the transmission process.

[0021] In an alternative embodiment of the present invention, the transmission chain includes a first transmission chain and a second transmission chain. One end of the first transmission chain far from the input end is coaxially arranged with one end of the second transmission chain. The second transmission chain includes a first chain and a second chain. The first chain and the second chain are arranged in parallel at an interval to form a gap.

[0022] The first transmission chain and the second transmission chain are coaxially arranged, so that the first transmission chain and the second transmission chain can be simultaneously driven by the same driving wheel, and the synchronous movement of the first transmission chain and the second transmission chain can be realized. Among them, the second transmission chain includes a first chain and a second chain. The second transmission chain is driven in a double-chain manner. A gap is formed between the first chain and the second chain, so that the fruit cup part placed on the fixed component can be exposed outside, which is convenient for the detection unit below to detect information. In an alternative embodiment of the present invention, the detection unit includes a quality module, and the quality module is arranged below the gap.

[0023] The quality module is arranged below the gap formed by the first chain and the second chain. The quality module is mainly used to receive the spectrum after the light source passes through the fruit cup. The light source is arranged above the fruit cup. Receiving the spectrum from the bottom of the fruit cup can enable the fruit to fit better with the soft skin in the fruit cup, block the vast majority of non-transmitted light, and reduce the influence of non-transmitted light on the spectrum passing through the fruit. If the quality module is arranged above or on the side of the fruit cup, more natural light and diffusely reflected light will enter the quality module, affecting the detection accuracy of the quality module.

[0024] In an alternative embodiment of the present invention, a detection hole is arranged at the bottom of the fruit cup, and the detection hole is correspondingly arranged with the gap.

[0025] In order to improve the accuracy of the spectrum received by the quality module, a detection hole is arranged at the bottom of the fruit cup, which can increase the light transmittance and avoid weakening the intensity of the spectrum received by the quality module due to the relatively thick fruit cup.

[0026] In an alternative embodiment of the present invention, the transmission chain further includes a third transmission chain, and one end of the third transmission chain is coaxially arranged with the end of the second transmission chain far from the first transmission chain.

[0027] The third transmission chain is also a single chain. The second transmission chain is mainly arranged to receive the spectrum from below the fruit cup. Since the double-chain method is more costly than the single-chain method, only the double-chain method is used for transmission at the quality module detection point.

[0028] In an alternative embodiment of the present invention, the detection unit further includes a vision module and a weighing module, and the vision module and the weighing module are arranged below the first transmission chain.

[0029] Since the double-chain method is more costly than the single-chain method, only the double-chain method is used for transmission at the quality module detection point.

[0030] In an alternative embodiment of the present invention, the fixing component includes a mounting plate and a stop portion. The mounting plate is mounted on the conveying component, the stop portion is connected to the mounting plate, and the stop portion can abut against the fruit cup to enable the fruit cup to move driven by the conveying component.

[0031] The mounting plate is mounted on the second transmission chain. The stop portion is mainly used to abut against the fruit cup, so as to drive the fruit cup to be able to move on the second transmission chain. In an alternative embodiment of the present invention, the stop portion has a stop surface, and the stop surface can abut against the fruit cup.

[0032] During the process of the fruit cup transitioning from the first transmission chain to the second transmission chain, the stop surface gradually abuts against the fruit cup, thereby pushing the fruit cup to move on the second transmission chain.

[0033] In an alternative embodiment of the present invention, the shape of the stop surface is adapted to the shape of the fruit cup.

[0034] The shape of the stop surface is adapted to the shape of the fruit cup, which can ensure that the stop surface and the fruit cup can be completely fitted, improve the transmission stability of the fruit cup during the transmission process, and reduce the problem of fruit cup sliding caused by local contact between the stop surface and the fruit cup.

[0035] In an alternative embodiment of the present invention, the fixing component includes a bottom plate and a baffle. The bottom plate is mounted on the conveying component, the baffle is connected to the bottom plate, and the baffles and the bottom plates of two adjacent fixing components form a fixing cavity, and the fruit cup is mounted in the fixing cavity.

[0036] During the process of the first transmission chain or the third transmission chain transmitting the fruit cup, the bottom plate is mainly used to receive the fruit cup, and the baffles of two adjacent first fixing members limit the fruit cup from the front and back to ensure that the fruit cup can run on the first transmission chain or the third transmission chain.

[0037] In an alternative embodiment of the present invention, the detection component includes a detection switch and a detection disk. The detection disk is coaxially arranged with the conveying component. A plurality of detection ports are arranged on the detection disk, and the number of the detection ports is the same as the number of the fixing components. Under the condition that the detection port moves to a position corresponding to the detection switch, the detection switch detects a in-place signal indicating that the fixing component moves to the input end.

[0038] The detection switch is a photoelectric switch. When the detection port rotates to the detection port, the signal emitted by the photoelectric switch shoots out from the detection port. When the detection disk rotates to the interval between two detection ports, the photoelectric switch receives a feedback signal. Thus, it can be judged whether there is a detection port passing through the detection switch, and by detecting whether the detection port moves to the detection switch, it can be judged whether the fixing component moves to the input end.

[0039] In a second aspect, an embodiment of the present invention provides a fruit sorting method, which is applied to a fruit sorting device. The fruit sorting device includes: a conveying assembly, a fruit cup, a plurality of fixing components, and a plurality of detection units. The plurality of fixing components are sequentially installed on the conveying assembly, and the plurality of detection units are correspondingly arranged with the conveying assembly. The fruit sorting method includes:

[0040] Obtain an in-place signal of the carrying time information when the fixing component moves to the input end;

[0041] Obtain the running speed of the conveying assembly;

[0042] Obtain the detection information of the carrying time information collected by the detection unit at every preset time interval;

[0043] Obtain the distance between the detection component and the detection unit;

[0044] Match the detection information corresponding to the fruit cup corresponding to the in-place signal according to the running speed of the conveying assembly, the time information of the in-place signal, the distance between the detection unit and the detection component, and the time information of the detection information.

[0045] According to the starting time, running speed, distance between the detection unit and the detection component, and time information, the matching between the fruit cup and the detection information can be realized, the one-to-one correspondence between multiple detection information and multiple fruit cups can be realized, the influence of fruit cup loss on subsequent sorting can be avoided, and the problem of subsequent data disorder can be minimized as much as possible, thereby improving the accuracy of fruit sorting.

[0046] In an optional embodiment of the present invention, the step of matching the detection information corresponding to the in-place signal according to the running speed of the conveying assembly, the time information of the in-place signal, the distance between the detection unit and the detection component, and the time information of the detection information includes:

[0047] Calculate the movement time for the fixing component to drive the fruit cup to move from the detection component to the detection unit according to the running speed and the distance between the detection unit and the detection component;

[0048] Calculate the end time for the fixing component to drive the fruit cup to move from the detection component to the detection unit according to the time information of the in-place signal and the movement time;

[0049] Match the detection information with the same end time among the multiple detection information.

[0050] In the embodiment of the present invention, according to the starting time, running speed, distance between the detection unit and the detection component, and time information, the matching between the fruit cup and the detection information can be realized, so as to achieve a one-to-one correspondence between multiple detection information and multiple fruit cups, avoid the influence of fruit cup loss on subsequent sorting, and minimize the problem of subsequent data confusion as much as possible, thereby improving the accuracy of fruit sorting.

[0051] In an alternative embodiment of the present invention, the step of matching the detection information among the multiple detection information that is the same as the end time includes:

[0052] Determine whether there is detection information among the multiple detection information that is the same as the end time;

[0053] If there is, record the detection information that is the same as the end time into the detection data of the fruit cup corresponding to the in-place signal.

[0054] The detection unit will collect a detection information every preset time interval and send the detection information carrying time information to the control unit. The control unit then matches the detection information that is the same as the end time among the multiple detection information. If there is detection information that is the same as the end time, then this detection information is the detection data of this fruit cup, and then record this detection information into the detection data of this fruit cup.

[0055] In an alternative embodiment of the present invention, the step of matching the detection information among the multiple detection information that is the same as the end time includes:

[0056] If not, discard the detection data of the fruit cup corresponding to the in-place signal.

[0057] If there is no detection information that matches the end time among the multiple detection information, it may be that the fruit cup is lost during the movement to the detection unit, or the fruit cup is not lost, but the detection unit does not detect the detection information of this fruit cup. Then it means that there is no detection information of this fruit cup among the multiple detection information, so discard the detection data of this fruit cup and do not perform the next sorting work.

[0080] First Embodiment

[0081] Please refer to Figure 1 and Figure 2 In this embodiment, a fruit sorting device 100 is provided. The fruit sorting device 100 provided in this embodiment is mainly used for sorting fruits. The fruit sorting device 100 provided in this embodiment can, after receiving the detection information of the fruit cup 130 detected by the detection unit 140, match multiple detection information with the fruit cup 130, minimizing the problem of subsequent data confusion, thereby improving the accuracy of fruit sorting.

[0082] In this embodiment, the fruit sorting device 100 includes: a control unit 110, a conveying component 120, a detection component 160, a fruit cup 130, a plurality of fixing components 150, and a plurality of detection units 140; the fruit cup 130 is used to accommodate fruits; the fixing component 150 is used to fix the fruit cup 130.

[0083] The detection component 160 is arranged at the input end of the conveying component 120. The detection component 160 is connected to the control unit 110 and is used to detect the in-place signal of the fixing component 150 moving to the input end, and send the in-place signal carrying the starting time to the control unit 110. A plurality of fixing components 150 are sequentially installed on the conveying component 120, and drive a plurality of fruit cups 130 to pass through a plurality of detection units 140 in sequence under the action of the conveying component 120. A plurality of detection units 140 are connected to the control unit 110. The detection unit 140 is used to collect the detection information of the fruit cup 130 every preset time interval, and send the detection information carrying the time information to the control unit 110.

[0084] The control unit 110 is used to be connected to the detection unit 140 and the detection component 160, and is used to receive a plurality of detection information, and match the detection information corresponding to the fruit cup 130 of the in-place signal according to the running speed of the conveying component 120, the starting time of the in-place signal, the distance between the detection unit 140 and the detection component 160, and the time information of the detection information.

[0085] In this embodiment, the fruit is placed in the fruit cup 130, and the fruit cup 130 is fixed on the fixing component 150. Under the action of the conveying component 120, the fixing component 150 drives the fruit cup 130 to sequentially pass through a plurality of detection units 140 arranged in the extending direction of the conveying component 120. The position where the fruit cup 130 is placed on the input end through the fixing component 150 can be regarded as the starting position of the movement of the fruit cup 130 on the conveying component 120. Obtaining the in-place signal when the fixing component 150 moves to the input end can be regarded as obtaining the starting time when the fixing component 150 drives the fruit cup 130 on the conveying component 120. According to the starting time, the running speed, and the distance between the detection unit 140 and the detection component 160, the detection information corresponding to the fruit cup 130 detected at the detection unit 140 can be matched. In this embodiment, according to the starting time, the running speed, the distance between the detection unit 140 and the detection component 160, and the time information, the matching between the fruit cup 130 and the detection information can be realized, and the one-to-one correspondence between a plurality of detection information and a plurality of fruit cups 130 can be achieved, avoiding the influence of the loss of the fruit cup 130 on the subsequent sorting, and minimizing the problem of subsequent data confusion as much as possible, thereby improving the accuracy of fruit sorting.

[0086] It is easy to understand that there are multiple detection units 140. After the control unit 110 receives the detection information of the same detection unit 140, the processing methods are the same, and the above method is used to process the detection information detected by the same detection unit 140, thereby realizing the multiple sorting of fruits.

[0087] Among them, the running speed can be preset or directly obtained by the control unit 110 from the conveying component 120. Generally, in order to facilitate the acquisition of detection information by the detection unit 140, the conveying component 120 generally moves at a constant speed, that is, the running speed is a fixed value. When the entire fruit sorting device 100 is started, it can be that the control unit 110 controls the conveying component 120 to convey the fruit cup 130 at the running speed according to the start instruction. It can also be that after the fruit sorting device 100 is started, the control unit 110 directly detects the running speed of the conveying component 120. A plurality of fixing components 150 are evenly spaced on the conveying component 120. The interval time when two adjacent fixing components 150 pass through the detection unit 140 can be calculated according to the running speed of the conveying component 120 and the distance between two adjacent fixing components 150. The interval time can be set as a preset time. That is to say, when each fixing component 150 moves to the detection unit 140, the detection unit 140 collects detection information once.

[0088] For example: the running speed is 20 mm / s, the distance between two adjacent fixed components 150 is 40 mm, and the interval time calculated based on the running speed and the distance between two adjacent fixed components 150 is 2 s. For a single detection unit 140, detection information is obtained every 2 s.

[0089] Of course, in order to improve the detection effect of the detection unit 140, the preset time can be less than the interval time, and it is only necessary to ensure that the interval time is an integer multiple of the preset time. That is to say, the preset time can be one-half, one-third, etc. of the interval time. That is, the interval time can be 1 s, 0.5 s, etc.

[0090] A plurality of fixed components 150 are evenly arranged on the conveying component 120, and the distance between the detection component 160 and the detection unit 140 can be calculated according to the number of fixed components 150 between the detection component 160 and the detection unit 140.

[0091] For the convenience of understanding, taking the detection unit 140 closest to the detection component 160 as an example, specifically: when the fixed component 150 moves to the detection component 160, and the current fixed component 150 is numbered, according to the order of passing through the detection component 160, the numbering orders of the plurality of fixed components 150 are respectively number 1, number 2, number 3, number 4, number 5, number 6, etc. When calculating the distance between the detection component 160 and the detection unit 140, when the current detection component 160 detects a in-place signal of a fixed component 150, the fixed component 150 currently at the detection component 160 is recorded as number 6. And currently, the fixed component 150 numbered 3 moves to the detection unit 140, then there are 3 intervals between the detection component 160 and the detection unit 140, and the distance between the detection component 160 and the detection unit 140 is 3 multiplied by 40 mm to get 120 mm.

[0092] In this embodiment, the in-place signal carrying the starting time refers to that the detection component 160 records the time point when the in-place signal of the fixed component 150 is detected while detecting the in-place signal of the fixed component 150, and the time point when the in-place signal is detected is the starting time of the in-place signal.

[0093] For example: taking the start of the fruit sorting device 100 as the 0 moment, at this time, the detection component 160 just detects an in-place signal, then the starting time of this in-place signal is 0. The in-place signal carrying the starting time is: 0 s - signal 1. Since the fixed components 150 are evenly arranged on the conveying component 120, the in-place signals carrying the starting time detected by the detection component are respectively: 0 s - signal 1, 2 s - signal 2, 4 s - signal 3, 6 s - signal 4, etc.

[0094] The detection information carrying time information refers to the time point when the detection unit 140 records the detection information of the fruit cup 130 while detecting the detection information of the fruit cup 130. Then, the time point when the detection information is detected is the time information of the detection information. For the convenience of understanding, taking the detection unit 140 closest to the detection component 160 as an example, specifically: during the process that the detection unit 140 obtains the detection information at intervals of a preset time, the time when the detection information is received will be recorded while recording the detection information, and sent to the control unit 110. The detection information received by the control unit is: 0s - Information 1, 2s - Information 2, 4s - Information 3, 6s - Information 4, etc.

[0095] In this embodiment, the control unit 110 is further configured to calculate the movement time for the fixing component 150 to drive the fruit cup 130 from the detection component 160 to the detection unit 140 according to the running speed and the distance between the detection unit 140 and the detection component 160, and calculate the end time for the fixing component 150 to move to the detection unit 140 according to the start time of the in-place signal and the movement time, and match the detection information with the same end time as the time information.

[0096] In this embodiment, after obtaining the running speed of the conveying component 120, the movement time required for the fixing component 150 to move from the input end to the detection unit 140 can be calculated according to the running speed and the distance between the detection unit 140 and the detection component 160, and the end time for the fixing component 150 to move to the detection unit 140 can be calculated according to the start time obtained by the fixing component 150 at the input end. The end time can be obtained by adding the movement time to the start time. According to the end time, the detection information with the same time information and end time can be matched among multiple detection information. This detection information is the detection information of the fruit cup 130 detected by the detection unit 140 when the fixing component 150 moves to the detection unit 140.

[0097] In this embodiment, if there is detection information that matches the end time among multiple detection information, the detection information will be recorded into the detection data of the fruit cup 130 corresponding to the in-place signal.

[0098] The detection unit 140 will collect a detection information after each interval of the preset time, and send the detection information carrying time information to the control unit 110. The control unit 110 will match the detection information with the same end time among multiple detection information. If there is detection information with the same end time, this detection information is the detection data of the fruit cup 130, and this detection information will be recorded into the detection data of the fruit cup 130.

[0099] In this embodiment, if there is no detection information that matches the end time among multiple detection information, the detection data of the fruit cup 130 corresponding to the in-place signal will be discarded.

[0100] If there is no detection information matching the end time among multiple detection information, it may be that the fruit cup 130 is lost during the movement to the detection unit 140, or the fruit cup 130 is not lost, but the detection unit 140 does not detect the detection information of the fruit cup 130. This indicates that there is no detection information of the fruit cup 130 among the multiple detection information, so the detection data of the fruit cup 130 is discarded and the next sorting work is not carried out.

[0101] It is easy to understand that in this embodiment, there are multiple detection units 140, and the control unit 110 performs matching according to the above method after receiving the detection data of the same detection unit 140.

[0102] To facilitate understanding of the process of matching the detection information with the fruit cup 130, take an example of any fruit cup 130 fixed on the fixing component 150 and driven by the conveying component 120 to pass through the detection unit 140 closest to the detection component 160 for specific description. After the fruit sorting device 100 is started, the detection unit 140 detects multiple detection information with time information, which are: 0s - Information 1, 2s - Information 2, 4s - Information 3, 6s - Information 4, 8s - Information 5, 10s - Information 6, 12s - Information 7, 14s - Information 8, and so on.

[0103] When the corresponding fixing component 150 is applied to the detection component 160, the detection component 160 detects the in - place signal with the start time as 6s - Signal 4. According to the running speed of 20 mm / s and the distance of 120 mm between the detection unit 140 and the detection component 160, the movement time of 6s can be calculated. Then, by adding the movement time of 6s to the start time of 6s detected by the detection component 160, the time information of 12s is calculated. Then, it is matched whether there is detection information with the time information of 12s among the detection information with time information detected by the detection unit 140. It is found that there is detection information of 12s - Information 7, so Information 7 is the detection information of the fruit cup 130, and Information 7 is recorded in the detection data of the fruit cup 130.

[0104] Similarly, when the fruit cup 130 passes through other detection units 140, the calculation process is the same as the above method. Since the positions of different detection units 140 and the detection component 160 are different, the calculated movement times are different, and the above - mentioned matching of detection information can be referred to.

[0105] Please refer to Figure 2 and Figure 3 , in this embodiment, the conveying component 120 includes a transmission chain 124 and a driving wheel 122. The transmission chain 124 is in transmission connection with the driving wheel 122, and multiple fixing components 150 are sequentially installed on the transmission chain 124.

[0106] In this embodiment, a plurality of fixing components 150 are evenly spaced and installed on the transmission chain 124. Driven by the driving wheel 122, the transmission chain 124 can drive the fruit cups 130 fixed on the fixing components 150 to sequentially pass through a plurality of detection units 140. The transmission by means of the driving wheel 122 and the transmission chain 124 can increase the stability of the transmission component 120 during the transmission process and reduce the problem of slipping of the transmission component 120 during the transmission process.

[0107] In this embodiment, the transmission chain 124 includes a first transmission chain 1242 and a second transmission chain 1244. One end of the first transmission chain 1242 away from the input end is coaxially arranged with one end of the second transmission chain 1244. The second transmission chain 1244 includes a first chain 1245 and a second chain 1246. The first chain 1245 and the second chain 1246 are arranged in parallel at an interval to form a gap.

[0108] In this embodiment, the first transmission chain 1242 and the second transmission chain 1244 are coaxially arranged, so that the first transmission chain 1242 and the second transmission chain 1244 can be simultaneously driven by the same driving wheel 122, the synchronous movement of the first transmission chain 1242 and the second transmission chain 1244 can be realized, and the sorting of different functions of fruits can be realized.

[0109] Among them, the second transmission chain 1244 includes a first chain 1245 and a second chain 1246. The second transmission chain 1244 is driven in a double-chain manner. A gap is formed between the first chain 1245 and the second chain 1246, so that part of the fruit cup 130 placed on the fixing component 150 can be exposed outside, which is convenient for the detection unit 140 below to detect information.

[0110] In this embodiment, the first transmission chain 1242 is driven in a single-chain manner, and the second transmission chain 1244 is driven in a double-chain manner. Since the structures of the first transmission chain 1242 and the second transmission chain 1244 are different, the structures of the fixing components 150 of the first transmission chain 1242 and the fixing components 150 of the second transmission chain 1244 are different.

[0111] Please refer to Figure 4 , in this embodiment, the detection unit 140 includes a quality module 142, and the quality module 142 is arranged below the gap.

[0112] In this embodiment, the quality module 142 is disposed below the gap formed between the first chain 1245 and the second chain 1246. The quality module 142 is mainly used to receive the spectrum of the light source 170 after passing through the fruit cup 130. The light source 170 is disposed above the fruit cup 130. Receiving the spectrum from the bottom of the fruit cup 130 enables the fruit to fit well with the soft skin inside the fruit cup 130, blocking the vast majority of non-transmitted light and reducing the influence of non-transmitted light on the spectrum passing through the fruit. If the quality module 142 is disposed above or on the side of the fruit cup 130, more natural light and diffusely reflected light will enter the quality module 142, affecting the detection accuracy of the quality module 142.

[0113] Secondly, receiving the spectrum from the bottom of the fruit cup 130 allows for lighting from the middle of the fruit regardless of its size, providing better compatibility for large and small fruits and being able to accommodate fruits of different sizes. When receiving from above or the side, large fruits will be lit below the fruit and small fruits will be lit above the fruit, resulting in poor compatibility. For fruits with significant size differences, multiple specifications of fruit cups 130 need to be designed. Some smaller fruits may even sink directly into the fruit cup 130, and even if the fruit cup 130 is made smaller, it will be impossible to detect due to severe light leakage.

[0114] Please refer to Figure 5 , in this embodiment, a detection hole 132 is provided at the bottom of the fruit cup 130, and the detection hole 132 is correspondingly disposed with the gap. The corresponding disposition can be considered that the projection of the detection hole 132 in the vertical direction coincides with the gap. To improve the accuracy of the spectrum received by the quality module 142, providing the detection hole 132 at the bottom of the fruit cup 130 can increase the light transmittance and avoid weakening the intensity of the spectrum received by the quality module 142 due to the relatively thick fruit cup 130.

[0115] To improve the quality of the spectrum received by the quality module 142, the detection hole 132 is preferably disposed at the center of the fruit cup 130 to enable the spectrum to pass through the detection hole 132 as much as possible.

[0116] In addition, the aperture of the detection hole 132 should not be too large. If the aperture of the detection hole 132 is too large, fruits with a smaller fruit diameter may fall through the detection hole 132, and the aperture of the detection hole 132 should be adapted to the fruit diameter of the fruit.

[0117] Similarly, the distance between the first chain 1245 and the second chain 1246 should not be too small or too large. If the distance between the first chain 1245 and the second chain 1246 is too large, the fixing components 150 on the first chain 1245 and the second chain 1246 will not be convenient for fixing the fruit cup 130. If the distance between the first chain 1245 and the second chain 1246 is too small, the light source may not be able to completely pass through the gap.

[0118] In this embodiment, the transmission chain 124 further includes a third transmission chain 1248. One end of the third transmission chain 1248 is coaxially arranged with the end of the second transmission chain 1244 away from the first transmission chain 1242.

[0119] In this embodiment, the first transmission chain 1242, the second transmission chain 1244, and the third transmission chain 1248 are arranged in sequence. The input end is arranged at the end of the first transmission chain 1242 away from the second transmission chain 1244. After the fruit cup 130 is placed on the input end, it is transmitted on the first transmission chain 1242, the second transmission chain 1244, and the third transmission chain 1248 in sequence.

[0120] Among them, the third transmission chain 1248 is also a single chain. The second transmission chain 1244 is mainly provided to receive the spectrum from below the fruit cup 130. Since the double-chain method has a higher cost than the single-chain method, in this embodiment, only the double-chain method is used for transmission at the detection part of the quality module 142.

[0121] It is easy to understand that in this embodiment, the first transmission chain 1242 and the third transmission chain 1248 have the same structure.

[0122] In this embodiment, the first transmission chain 1242 is coaxially connected to the second transmission chain 1244. The end of the second transmission chain 1244 away from the first transmission chain 1242 is coaxially connected to the third transmission chain 1248. The driving wheel 122 is in transmission connection with the first transmission chain 1242. The driving wheel 122 drives the first transmission chain 1242 to rotate. The first transmission chain 1242 drives the second transmission chain 1244 to rotate through the transmission shaft connected to the second transmission chain 1244. Similarly, the second transmission chain 1244 drives the third transmission chain 1248 to rotate through the transmission shaft connected to the third transmission chain 1248, so as to realize the synchronous rotation of the first transmission chain 1242, the second transmission chain 1244, and the third transmission chain 1248.

[0123] In this embodiment, the detection unit 140 further includes a vision module 144 and a weighing module 146. The vision module 144 and the weighing module 146 are arranged below the first transmission chain 1242. The fruit sorting device 100 further includes a sorting module 148. The sorting module 148 is arranged below the third transmission chain 1248.

[0124] The vision module 144 is mainly used to collect the image information of the fruit. The weighing module 146 is mainly used to weigh the fruit. The sorting module 148 is mainly used to obtain the overall data of the fruit according to the data integration of the quality module 142, the vision module 144, and the weighing module 146, and then sort the grades of the fruit according to the integrated overall data.

[0125] Please refer to Figure 6 andFigure 7 , in this embodiment, the structures of the first transmission chain 1242 and the third transmission chain 1248 are the same, and the structure of the second transmission chain 1244 is different from those of the first transmission chain 1242 and the third transmission chain 1248. Then, the structures of the fixing components 150 on the first transmission chain 1242 are the same as those of the fixing components 150 on the third transmission chain 1248, and the fixing components 150 on the second transmission chain 1244 have different structures. In order to distinguish between the two different fixing components 150, the fixing components 150 on the first transmission chain 1242 and the third transmission chain 1248 are defined as the first fixing members 152, and the fixing components 150 on the second transmission chain 1244 are defined as the second fixing members 154.

[0126] In this embodiment, the fixing component 150 includes a bottom plate 1521 and a baffle 1523. The bottom plate 1521 is installed on the conveying component 120, and the baffle 1523 is connected to the bottom plate 1521. The baffles 1523 and the bottom plates 1521 of two adjacent fixing components 150 form a fixing cavity, and the fruit cup 130 is installed in the fixing cavity.

[0127] In this embodiment, the first fixing member 152 includes a bottom plate 1521 and a baffle 1523. The bottom plate 1521 is installed on the first transmission chain 1242 or the third transmission chain 1248. The fruit cup 130 is placed in the fixing cavity. During the process of the first transmission chain 1242 or the third transmission chain 1248 transporting the fruit cup 130, the bottom plate 1521 is mainly used to receive the fruit cup 130, and the baffles 1523 of two adjacent first fixing members 152 limit the fruit cup 130 from the front and back of the fruit cup 130 to ensure that the fruit cup 130 can run on the first transmission chain 1242 or the third transmission chain 1248.

[0128] In order to improve the limiting effect of the baffle 1523 on the fruit cup 130, the baffle 1523 can be set to be perpendicular to the bottom plate 1521.

[0129] Of course, in other embodiments of the present invention, the baffle 1523 can be set at other angles with the bottom plate 1521 as long as it can play a role in limiting the fruit cup 130.

[0130] Please refer to Figure 8 and Figure 9 , in this embodiment, the fixing component 150 includes a mounting plate 1542 and a stop portion 1544. The mounting plate 1542 is installed on the conveying component 120, and the stop portion 1544 is connected to the mounting plate 1542. The stop portion 1544 can abut against the fruit cup 130 to make the fruit cup 130 move driven by the conveying component 120.

[0131] In this embodiment, the second fixing member 154 includes a mounting plate 1542 and a stopping portion 1544. The mounting plate 1542 is mounted on the second transmission chain 1244, and the stopping portion 1544 is mainly used to abut against the fruit cup 130, so as to drive the fruit cup 130 to move on the second transmission chain 1244.

[0132] It should be noted that in this embodiment, the second fixing members 154 are provided on both the first chain 1245 and the second chain 1246 of the second transmission chain 1244, and the second fixing members 154 on the first chain 1245 and the second fixing members 154 on the second chain 1246 are arranged in one-to-one correspondence. That is, the second fixing members 154 on the first chain 1245 and the second fixing members 154 on the second chain 1246 at the same position cooperate together to fix the fruit cup 130 simultaneously.

[0133] That is to say, the two second fixing members 154 at the same position fix the fruit cup 130 from different positions of the fruit cup 130 respectively, and push the fruit cup 130 to move on the second transmission chain 1244.

[0134] The distance between the first fixing members 152 on the first transmission chain 1242 is the same as the distance between the second fixing members 154 on the second transmission chain 1244. When the first fixing member 152 moves to the transmission shaft of the first transmission chain 1242 and the second transmission chain 1244, just the second fixing member 154 on the second transmission chain 1244 rotates from below the second transmission chain 1244 to above the second transmission chain 1244. During the process of rotating at the same speed, the first fixing member 152 gradually rotates to below the first transmission chain 1242, and the stopping portion 1544 of the second fixing member 154 gradually contacts the fruit cup 130, so that the fruit cup 130 can be transferred from the first transmission chain 1242 to the second transmission chain 1244.

[0135] In this embodiment, the gaps between the first transmission chain 1242 and the third transmission chain 1248 and the second transmission chain 1244 are correspondingly arranged, so as to avoid interference between the first fixing member 152 and the second fixing member 154 during the process of the fruit cup 130 transitioning from the first transmission chain 1242 to the second transmission chain 1244 and during the process of transitioning from the second transmission chain 1244 to the third transmission chain 1248.

[0136] In this embodiment, the stopping portion 1544 has a stopping surface 1546, and the stopping surface 1546 can abut against the fruit cup 130. During the process of the fruit cup 130 transitioning from the first transmission chain 1242 to the second transmission chain 1244, the stopping surface 1546 gradually abuts against the fruit cup 130, so as to push the fruit cup 130 to move on the second transmission chain 1244.

[0137] In this embodiment, the shape of the stop surface 1546 is adapted to the shape of the fruit cup 130. This can ensure that the stop surface 1546 and the fruit cup 130 are fully fitted, improving the transmission stability of the fruit cup 130 during the transmission process and reducing the problem of the fruit cup 130 sliding due to local contact between the stop surface 1546 and the fruit cup 130.

[0138] For example: when the shape of the fruit cup 130 is circular, the shape of the stop surface 1546 is also circular. When the shape of the fruit cup 130 is rectangular, the shape of the stop surface 1546 is also rectangular, as long as it is ensured that the stop surface 1546 can be fully fitted with the fruit cup 130.

[0139] In this embodiment, in order to increase the contact area between the entire second fixing member 154 and the bottom of the fruit cup 130, the second fixing member 154 further includes a connecting plate 1548. The connecting plate 1548 is installed on the second transmission chain 1244 and is spaced from the mounting plate 1542.

[0140] In this embodiment, when the fruit cup 130 is on the first transmission chain 1242, two adjacent first fixing members 152 clamp the fruit cup 130. When the fruit cup 130 moves to the transmission shaft of the first transmission chain 1242 and the second transmission chain 1244, the baffle 1523 of the first fixing member 152 in front of the fruit cup 130 on the first transmission chain 1242 gradually moves below the first transmission chain 1242, thus disengaging from the abutment with the fruit cup 130. The stop surface 1546 of the second transmission chain 1244 moves to fit with the fruit cup 130, thereby pushing the fruit cup 130 to be transmitted on the second transmission chain 1244. When the fruit cup 130 moves to the transmission shaft of the second transmission chain 1244 and the third transmission chain 1248, similarly, the first fixing member 152 on the third transmission chain 1248 is transmitted to the connection of the second transmission chain 1244 and the second transmission chain 1244, and limits the fruit cup 130 in front of the fruit cup 130 to prevent the fruit cup 130 from flying out of the third transmission chain 1248. During the continuous transmission process, the second fixing member 154 of the second transmission chain 1244 gradually rotates below the second transmission chain 1244, and another first fixing member 152 of the third transmission chain 1248 rotates above the third transmission chain 1248, thereby fixing the fruit cup 130.

[0141] Please refer to Figure 10 In this embodiment, the detection assembly 160 includes a detection switch 162 and a detection disk 164. The detection disk 164 is coaxially arranged with the transmission assembly 120. A plurality of detection ports 166 are provided on the detection disk 164. The number of detection ports 166 is the same as the number of the fixing assemblies 150. Under the condition that the detection port 166 moves to a position corresponding to the detection switch 162, the detection switch 162 detects a signal indicating that the fixing assembly 150 has moved to the input end.

[0142] In this embodiment, since the conveying assembly 120 includes a first transmission chain 1242, a second transmission chain 1244, and a third transmission chain 1248, and the detection assembly 160 is disposed on the first transmission chain 1242, the number of detection ports 166 needs to be the same as the number of first fixing members 152 of the first transmission chain 1242, and the detection disk 164 is coaxially disposed with one end of the first transmission chain 1242 away from the second transmission chain 1244.

[0143] Among them, the detection switch 162 is a photoelectric switch. When the detection port 166 rotates to the detection port 166, the signal emitted by the photoelectric switch is emitted from the detection port 166. When the detection disk 164 rotates to the interval between two detection ports 166, the photoelectric switch receives a feedback signal. Thus, it can be determined whether a detection port 166 passes through the detection switch 162, and by detecting whether the detection port 166 moves to the detection switch 162, it can be determined whether the fixing assembly 150 moves to the input end.

[0144] The working principle of the fruit sorting device 100 provided in this embodiment: In this embodiment, after obtaining the running speed of the conveying assembly 120, the movement time required for the fixing assembly 150 to move from the input end to the detection unit 140 can be calculated according to the running speed and the distance between the detection unit 140 and the detection assembly 160, and the end time when the fixing assembly 150 moves to the detection unit 140 can be calculated based on the start time obtained by the fixing assembly 150 at the input end. The end time can be obtained by adding the movement time to the start time. According to the end time, the detection information with the same time information and end time can be matched among multiple detection information, and this detection information is the detection information of the fruit cup 130 detected by the detection unit 140 when the fixing assembly 150 moves to the detection unit 140.

[0145] In summary, for the fruit sorting device 100 provided in this embodiment, in this embodiment, fruits are placed in the fruit cups 130, and the fruit cups 130 are fixed on the fixing component 150. Under the action of the conveying component 120, the fixing component 150 drives the fruit cups 130 to sequentially pass through a plurality of detection units 140 arranged in the extending direction of the conveying component 120. The input end where the fruit cup 130 is placed on the fixing component 150 can be regarded as the starting position of the movement of the fruit cup 130 on the conveying component 120. Obtaining the in-place signal when the fixing component 150 moves to the input end can be regarded as obtaining the starting time when the fixing component 150 drives the fruit cup 130 on the conveying component 120. According to the starting time, the running speed, and the distance between the detection unit 140 and the detection component 160, the detection information corresponding to the fruit cup 130 detected at the detection unit 140 can be matched. In this embodiment, according to the starting time, the running speed, the distance between the detection unit 140 and the detection component 160, and the time information, the matching between the fruit cup 130 and the detection information can be realized, and the one-to-one correspondence between a plurality of detection information and a plurality of fruit cups 130 can be realized, avoiding the influence of the loss of the fruit cup 130 on the subsequent sorting, and minimizing the problem of subsequent data confusion as much as possible, thereby improving the accuracy of fruit sorting.

[0146] Second Embodiment

[0147] This embodiment provides a fruit sorting method. After receiving the detection information of the fruit cup 130 detected by the detection unit 140, the fruit sorting method provided in this embodiment can match a plurality of detection information with the fruit cup 130, minimizing the problem of subsequent data confusion as much as possible, thereby improving the accuracy of fruit sorting.

[0148] For the sake of brief description, for the parts not mentioned in this embodiment, reference may be made to the first embodiment.

[0149] The specific steps of the fruit sorting method are as follows:

[0150] Please refer to Figure 11 , step S100, obtain the in-place signal carrying the starting time when the fixing component 150 moves to the input end.

[0151] In this embodiment, the in-place signal carrying the starting time refers to the time point when the detection component 160 records the in-place signal of the fixing component 150 while detecting the in-place signal, and the time point when the in-place signal is detected is the starting time of the in-place signal.

[0152] Step S200, obtain the running speed of the conveying component 120.

[0153] In this embodiment, the running speed can be preset or directly obtained by the control unit 110 from the conveying component 120. When the entire fruit sorting device 100 is started, it can be that the control unit 110 controls the conveying component 120 to convey the fruit cup 130 at the running speed according to the start instruction. It can also be that after the fruit sorting device 100 is started, the control unit 110 directly detects the running speed of the conveying component 120.

[0154] Step S300: Obtain the detection information carrying time information collected by the detection unit 140 at preset time intervals.

[0155] In this embodiment, the detection information carrying time information refers to the time point when the detection unit 140 records the detection information when detecting the detection information of the fruit cup 130, and the time point when the detection information is detected is the time information of the detection information.

[0156] A plurality of fixing components 150 are arranged at intervals on the conveying component 120. The interval time when two adjacent fixing components 150 pass through the detection unit 140 can be calculated according to the running speed of the conveying component 120 and the distance between two adjacent fixing components 150. The interval time can be set as the preset time. That is to say, when each fixing component 150 moves to the detection unit 140, the detection unit 140 collects the detection information once.

[0157] Step S400: Obtain the distance between the detection component 160 and the detection unit 140.

[0158] In this embodiment, a plurality of fixing components 150 are evenly arranged at intervals on the conveying component 120, and the distance between the fixing components 150 is fixed. The distance between the detection component 160 and the detection unit 140 can be calculated according to the number of fixing components 150 between the detection component 160 and the detection unit 140.

[0159] Step S500: Match the detection information corresponding to the fruit cup 130 with the in-place signal according to the running speed of the conveying component 120, the time information of the in-place signal, the distance between the detection unit 140 and the detection component 160, and the time information of the detection information.

[0160] In this embodiment, according to the starting time, running speed, the distance between the detection unit 140 and the detection component 160, and the time information, the matching between the fruit cup 130 and the detection information can be realized, and the one-to-one correspondence between multiple detection information and multiple fruit cups 130 can be realized, avoiding the influence of the loss of the fruit cup 130 on the subsequent sorting, and minimizing the problem of subsequent data confusion as much as possible, thereby improving the accuracy of fruit sorting.

[0161] Please refer to Figure 12, wherein, step S500 may include step S510, step S520, and step S530.

[0162] Step S510, calculate the movement time for the fixing component 150 to drive the fruit cup 130 from the detection component 160 to the detection unit 140 based on the running speed and the distance between the detection unit 140 and the detection component 160.

[0163] In this embodiment, after obtaining the running speed of the conveying component 120, the movement time required for the fixing component 150 to move from the input end to the detection unit 140 can be calculated according to the running speed and the distance between the detection unit 140 and the detection component 160.

[0164] Step S520, calculate the end time for the fixing component 150 to drive the fruit cup 130 from the detection component 160 to the detection unit 140 based on the time information of the in-place signal and the movement time.

[0165] Based on the start time obtained by the fixing component 150 at the input end, the end time for the fixing component 150 to move to the detection unit 140 can be calculated. The end time can be obtained by adding the movement time to the start time.

[0166] Step S530, match the detection information in multiple detection information that is the same as the end time.

[0167] According to the end time, the detection information with the same time information as the end time can be matched among multiple detection information. This detection information is the detection information of the fruit cup 130 detected by the detection unit 140 when the fixing component 150 moves to the detection unit 140.

[0168] Please refer to Figure 13 , wherein, step S530 may include step S532, step S534, and step S536.

[0169] Step S532, determine whether there is detection information in multiple detection information that is the same as the end time.

[0170] In this embodiment, the detection unit 140 collects a detection information at every preset time interval, and sends the detection information carrying time information to the control unit 110. The control unit 110 then matches the detection information that is the same as the end time among multiple detection information.

[0171] Step S534, if there is, record the detection information that is the same as the end time into the detection data of the fruit cup 130 corresponding to the in-place signal.

[0172] If there is detection information that is the same as the end time, then this detection information is the detection data of the fruit cup 130, and this detection information is recorded into the detection data of the fruit cup 130.

[0173] Step S536, if not, discard the detection data of the fruit cup 130 corresponding to the in-place signal.

[0174] If there is no detection information that matches the end time among multiple detection information, it may be that the fruit cup 130 is lost during the movement to the detection unit 140, or the fruit cup 130 is not lost, but the detection unit 140 does not detect the detection information of the fruit cup 130. This indicates that there is no detection information of the fruit cup 130 among multiple detection information, so the detection data of the fruit cup 130 is discarded and the next sorting work is not carried out.

[0175] For example: the distance between the vision module 144 and the detection component 160 is X fixed components 150, the distance between the weighing module 146 and the detection component 160 is Y fixed components 150, the distance between the quality module 142 and the detection component 160 is Z fixed components 150, and the distance between the sorting module and the detection component is M fixed components 150.

[0176] Every time the detection component 160 moves to a fixed component 150, the detection component 160 will detect an in-place signal and transmit it to the control unit 110, and the control unit 110 can obtain a detection data from the vision module 144, the weighing module 146 and the quality module 142.

[0177] When the in-place signal is N, the data output by the vision module 144 is An, the data output by the weighing module 146 is Bn, and the output of the quality module 142 is Cn.

[0178] After integration using the fruit sorting method provided in this embodiment, when the in-place signal of a certain fixed component 150 is N, the corresponding data of the vision module 144, the weighing module 146 and the quality module 142 should be An + X, Bn + Y, Cn + Z respectively. The three data are integrated into Dn and sent to the sorting module 148, and the sorting module 148 performs grading sorting according to Dn.

[0179] As described above, the above is only the specific implementation manner 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 those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
