The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0031] In order to solve the problems of low sorting reliability and high cost in the manual material sorting method in the prior art, the present application provides a sorting device.

[0032] like Figures 1 to 7 As shown, the sorting device includes: a conveying device 10, which is used to convey objects to be sorted and includes a first conveying structure 11 and a second conveying structure 12, wherein the first conveying structure 11 is used to convey the objects to be sorted to the second conveying structure 12; an image acquisition device 20, which is used to acquire images of the objects to be sorted located on the conveying device 10; a sorting device 30, which is connected to the image acquisition device 20, so as to sort the objects to be sorted according to the acquisition results of the image acquisition device 20; wherein there are at least two sorting devices 30, and at least one sorting device 30 is used to sort the objects to be sorted on the first conveying structure 11 to the cargo conveyor belt; at least another sorting device 30 has a cyclic sorting state and a regular sorting state, and when the sorting device 30 is in the cyclic sorting state, the sorting device 30 sorts the objects to be sorted on the second conveying structure 12 to the first conveying structure 11, so as to realize cyclic conveying of the objects to be sorted; when the sorting device 30 is in the regular sorting state, the sorting device 30 sorts the objects to be sorted on the second conveying structure 12 to the cargo conveyor belt.

[0033] Applying the technical solution of this embodiment, the conveying device 10 of the sorting equipment is used to convey the objects to be sorted and includes a first conveying structure 11 and a second conveying structure 12. The first conveying structure 11 is used to convey the objects to be sorted to the second conveying structure 12. The image acquisition device 20 is used to acquire images of the objects to be sorted located on the conveying device 10. The sorting device 30 is connected to the image acquisition device 20 to sort the objects to be sorted according to the acquisition results of the image acquisition device 20. Among them, there are at least two sorting devices 30, and at least one sorting device 30 is used to sort the objects to be sorted on the first conveying structure 11 to the cargo conveyor belt. At least another sorting device 30 has a cyclic sorting state and a regular sorting state. When the sorting device 30 is in the cyclic sorting state, the sorting device 30 sorts the objects to be sorted on the second conveying structure 12 to the first conveying structure 11 to realize cyclic transportation of the objects to be sorted. When the sorting device 30 is in a normal sorting state, the sorting device 30 sorts the objects to be sorted on the second conveying structure 12 onto the cargo conveyor belt. In this way, the sorting device in this embodiment realizes the automated sorting action of the sorting device 30 through the linkage between the image acquisition device 20 and the sorting device 30, and at the same time realizes the cyclic conveying and multiple sorting of the objects to be sorted through the sorting device 30 in the cyclic sorting state, that is, the objects to be sorted that are not identified and sorted by the sorting device 30 for sorting the objects to be sorted on the first conveying structure 11 can be conveyed by the first conveying structure 11 to the second conveying structure 12 for secondary sorting. If another sorting device 30 also fails to identify and sort the objects to be sorted, or recognizes that the objects to be sorted should be sorted by another sorting device 30, it can switch to the cyclic sorting state to sort the objects to be sorted to the first conveying structure 11 for re-sorting. The setting of cyclic conveying and multiple sorting of the objects to be sorted makes the sorting device as a whole have an accuracy comparable to or even higher than manual sorting. At the same time, the fully automated sorting process also makes the sorting equipment have extremely high sorting efficiency and can reduce human resource consumption and sorting costs, thereby solving the problems of low sorting reliability and high cost of manual material sorting methods in the existing technology.

[0034] In this embodiment, the sorting device further includes a display 60, which is connected to the control module of the sorting device for displaying corresponding sorting information (such as sorting quantity, sorted quantity of each type of objects to be sorted, operating time, etc.).

[0035] In this embodiment, the objects to be sorted may be express parcels, sheet metal parts, and other goods that need to be sorted, without limiting the usage scenarios of the sorting equipment.

[0036] In this embodiment, a plurality of sorted object conveying lines (cargo conveyor belts) are also provided on one side of the sorting device, and the sorted objects sorted out by the sorting device 30 are placed on the corresponding sorted object conveying lines and transported to different locations.

[0037] like Figure 1 , Figure 2 and Figure 5 As shown, the second conveying structure 12 includes a conveying body 121 and a carrier 122, the carrier 122 is located at the discharge side of the conveying body 121, and the conveying body 121 is used to convey the objects to be sorted to the carrier 122. Among them, the sorting device 30 with a cyclic sorting state and a conventional sorting state is a static sorting device 31, and the static sorting device 31 is arranged on the carrier 122 to sort the objects to be sorted on the carrier 122. In this way, this embodiment actually realizes the combination of dynamic sorting and static sorting, that is, sorting the objects to be sorted on the first conveying structure 11 is actually sorting the objects to be sorted in the process of movement (dynamic sorting), while sorting the objects to be sorted on the carrier 122 is static sorting (the objects to be sorted on the carrier 122 are stationary). The above arrangement helps to combine the respective advantages of static sorting and dynamic sorting, thereby greatly improving the sorting accuracy and sorting efficiency of the sorting equipment.

[0038] Specifically, the sorting efficiency of static sorting is lower than that of dynamic sorting, but static sorting is more accurate and is not prone to non-sorting problems due to the inability of the image acquisition device 20 to quickly identify the objects to be sorted during the sorting process. Dynamic sorting is the opposite of static sorting, with a higher sorting efficiency, but it is easy for the image acquisition device 20 to be unable to quickly identify the objects to be sorted due to the movement of the objects to be sorted, resulting in non-sorting problems. In the present embodiment, the sorting device combines two sorting methods, that is, a small amount of unsorted objects missed by the sorting device 30 for high-speed dynamic sorting of the objects to be sorted on the first conveying structure 11 can be conveyed to the second conveying structure 12, and then conveyed to the carrier 122 by the second conveying structure 12, and statically sorted by the static sorting device 31. The static sorting device 31 directly sorts the objects to be sorted that can be sorted and placed on the corresponding sorted object conveying line (conventional sorting state), and the objects to be sorted that cannot be sorted and placed on the corresponding sorted object conveying line will be re-sorted to the first conveying structure 11 and re-sorted by the dynamic sorting sorting device 30. The above arrangement can not only improve the sorting efficiency of the sorting device through dynamic sorting, but also realize accurate and complete sorting of the objects to be sorted through static sorting.

[0039] In this embodiment, the carrier 122 is a platform-like structure. In fact, it only needs to have a corresponding bearing surface for bearing the objects to be sorted, and its specific structure is not limited.

[0040] like Figure 1 , Figure 2 and Figure 5As shown, the first conveying structure 11 and the second conveying structure 12 are arranged at intervals along the height direction of the sorting device, and the second conveying structure 12 is located below the first conveying structure 11. Among them, the length of the conveying body 121 is greater than the length of the first conveying structure 11, so as to form a receiving section 1211 below the discharge side of the first conveying structure 11. In this way, the above arrangement helps to reduce the occupied area of ​​the conveying device 10 and realize the miniaturization of the sorting device. At the same time, the arrangement of the receiving section 1211 makes the transportation of the objects to be sorted between the first conveying structure 11 and the second conveying structure 12 simpler (gravity fall), which helps to reduce the processing cost of the sorting equipment.

[0041] like Figure 1 , Figure 2 and Figure 5 As shown, the conveying body 121 has a conveying surface 1212 for conveying objects to be sorted, and the conveying device 10 also includes: a connection structure 13, which is arranged on the receiving section 1211 and has a connection surface 131, one end of the connection surface 131 is connected to the conveying surface 1212, and at least part of the connection surface 131 is located on the falling path of the objects to be sorted that move out through the discharge side of the first conveying structure 11. Among them, the connection surface 131 and the conveying surface 1212 are arranged at an angle, and the objects to be sorted that fall on the connection surface 131 slide along the connection surface 131 to the conveying surface 1212 under the action of their gravity. In this way, the above-mentioned setting of the connection structure 13 can play a role in buffering and guiding the falling objects to be sorted. On the one hand, it can reduce the falling distance of the objects to be sorted, and then reduce the impact between the objects to be sorted and the conveying surface 1212, so as to extend the service life of the conveying body 121 and avoid damage to the objects to be sorted; on the other hand, it can ensure that the objects to be sorted can move smoothly to the conveying surface 1212.

[0042] In this embodiment, the conveying surface 1212 is arranged at an obtuse angle with the connecting surface 131 along its conveying direction, so as to ensure that the objects to be sorted can smoothly fall from the connecting surface 131 .

[0043] like Figure 5 As shown, the connection structure 13 includes: a plate-shaped connection body 132, a plate surface of which forms a connection surface 131; at least two enclosure structures 133, which are arranged on the receiving section 1211, and at least one enclosure structure 133 is arranged on both sides of the plate-shaped connection body 132, and the enclosure structure 133 is used to limit and stop the objects to be sorted. In this way, the above arrangement, on the one hand, limits and stops the objects to be sorted by the enclosure structure 133, so as to prevent the objects to be sorted that fall on the plate-shaped connection body 132 from falling to the outside of the conveying body 121; on the other hand, the structure of the connection structure 13 is simpler, easy to process and realize, and the processing cost of the connection structure 13 is also reduced.

[0044] In this embodiment, the enclosure structure 133 is plate-shaped, which is vertically arranged on the conveying body 121 and extends in the same direction as the conveying direction of the conveying body 121. There are actually two enclosure structures 133, with one enclosure structure 133 being arranged on each side of the plate-shaped connecting body 132.

[0045] like Figure 1 and Figure 2 As shown, the image acquisition device 20 is located above the conveying device 10. The image acquisition device 20 includes an image acquisition component 21 and a light source component 22. The image acquisition component 21 is used to acquire images of the objects to be sorted on the conveying device 10. The light source component 22 emits a light beam into the image acquisition area of ​​the image acquisition component 21 to increase the brightness in the image acquisition area. There are at least two image acquisition devices 20, and at least two image acquisition devices 20 are arranged in a one-to-one correspondence with at least two sorting devices 30. In this way, the setting of the light source component 22 can increase the brightness in the image acquisition area to improve the image acquisition clarity of the image acquisition component 21, thereby making the recognition and acquisition process of the image acquisition component 21 more accurate. At the same time, the number of image acquisition devices 20 is set to help increase the overall recognition range of the image acquisition device 20 to adapt to the setting position of each sorting device 30, ensuring that the sorting action of each sorting device 30 can be achieved.

[0046] Optionally, the image acquisition component 21 is an industrial camera.

[0047] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the sorting device 30 for sorting the objects to be sorted on the first conveying structure 11 is a dynamic sorting device 32, which is arranged on the first conveying structure 11. Along the height direction of the sorting device, the first conveying structure 11 avoids the carrier 122 to form a avoidance port 14 above the carrier 122; wherein, the image acquisition device 20 corresponding to the static sorting device 31 is located above the carrier 122, and the image acquisition device 20 corresponding to the dynamic sorting device 32 is located above the first conveying structure 11. In this way, the above arrangement enables each image acquisition device 20 to be located on the side of the sorting device 30 corresponding to it, so as to ensure that the image acquisition device 20 can accurately and clearly acquire the image within the sorting range of the sorting device 30 corresponding to it, thereby improving the sorting reliability of the sorting device 30. At the same time, the arrangement of the avoidance port 14 can avoid the image acquisition path of the image acquisition device 20 corresponding to the static sorting device 31.

[0048] In this embodiment, there is one static sorting device 31 and one dynamic sorting device 32. It should be noted that the number of static sorting devices 31 and dynamic sorting devices 32 is not limited thereto and can be adjusted accordingly according to working conditions and usage requirements.

[0049] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the sorting device also includes a frame 40, the first conveying structure 11 and the second conveying structure 12 are both arranged on the frame 40, the first conveying structure 11 includes at least two first belt conveying members 111 arranged along its conveying direction, the first belt conveying member 111 arranged near the feeding side of the first conveying structure 11 forms a feeding buffer section 112 on the first conveying structure 11; the conveying body 121 includes at least two second belt conveying members 1213 arranged along its conveying direction, the second belt conveying member 1213 arranged near the feeding side of the second conveying structure 12 forms a receiving section 1211, and the second belt conveying member 1213 arranged near the discharging side of the second conveying structure 12 forms a discharging buffer section 1214. In this way, the first conveying structure 11 and the conveying body 121 in this embodiment are actually spliced ​​by multiple belt conveying members, and the staff can adjust the conveying speed of each belt conveying member to ensure that the conveying speed of the object to be sorted can match the sorting speed of each sorting device 30, thereby avoiding the phenomenon of material accumulation and improving the operating stability of the sorting device.

[0050] Specifically, the outside of the frame 40 is also covered with a shell 50. The shell 50 can not only protect various devices and structures arranged on the frame 40, but also improve the aesthetics of the sorting equipment.

[0051] In this embodiment, the first conveying structure 11 includes two first belt conveyors 111 arranged along its conveying direction. The conveying speed of the first belt conveyor 111 used to form the feed buffer section 112 is smaller, that is, the objects to be sorted are sorted to the first conveying structure 11 via the static sorting device 31 and are placed on the feed buffer section 112. The feed buffer section 112 with a smaller conveying speed can prevent a large number of objects to be sorted from moving quickly to another first belt conveyor 111, causing a large number of objects to be sorted to stack on each other, thereby helping the dynamic sorting device 32 to perform efficient sorting.

[0052] It should be noted that the number of the first belt conveyors 111 in the first conveying structure 11 is not limited thereto, and can be adjusted according to working conditions and usage requirements.

[0053] In this embodiment, the conveying body 121 includes three second belt conveyors 1213 arranged along its conveying direction. The second belt conveyor 1213 arranged on the feed side close to the second conveying structure 12 forms a receiving section 1211, and the second belt conveyor 1213 arranged on the discharge side close to the second conveying structure 12 forms a discharge buffer section 1214. The second belt conveyor 1213 located between the receiving section 1211 and the discharge buffer section 1214 forms a feeding rising section 1215. The feeding rising section 1215 is inclined to lift the objects to be sorted to adapt to the overall structural layout of the conveying body 121.

[0054] Specifically, the conveying speed of the second belt conveyor 1213 used to form the discharge buffer section 1214 is lower. Its principle is similar to that of the feed buffer section 112 of the first conveying structure 11. It is also to avoid a large amount of objects to be sorted from being transported to the carrier 122 for stacking, thereby affecting the sorting process of the static sorting device 31.

[0055] like Figure 6 As shown, the first belt conveyor 111 and the second belt conveyor 1213 both include: a mounting bracket 151; at least two roller members 152, both of which are rotatably arranged on the mounting bracket 151; a conveyor belt 153, which is wound around at least two roller members 152 and rotates synchronously with the roller members 152; a driving device 154, which is arranged on the mounting bracket 151 and is drivingly connected to at least one roller member 152 through a transmission assembly 155, and the driving device 154 drives the roller member 152 to rotate to drive the conveyor belt 153 to rotate. In this way, the above arrangement drives the roller member 152 to rotate through the driving device 154, so as to drive the conveyor belt 153 to rotate, thereby realizing the conveying function of the belt conveyor.

[0056] In this embodiment, the driving device 154 is a servo motor.

[0057] Specifically, the transmission assembly 155 includes a driving wheel 1551, a driven wheel 1552 and a transmission belt 1553. The driving wheel 1551 is mounted on the output shaft of the driving device 154, and the driven wheel 1552 is mounted on a roller member 152. The driving wheel 1551 and the driven wheel 1552 are mounted with a transmission belt 1553, so that the driven wheel 1552 is driven to rotate through the driving wheel 1551, and then the roller member 152 is driven to rotate. The other roller member 152 is a passive roller member, which is rotatably set on the mounting bracket 151 through a bearing.

[0058] Specifically, in this embodiment, the actual structure of the mounting bracket 151 is not specifically limited, and corresponding adjustments, that is, adaptability improvements, can be made according to actual needs.

[0059] Specifically, a mounting seat for mounting the driving device 154 is also provided on the mounting bracket 151 .

[0060] Specifically, a tension adjustment block 156 is further provided on the mounting bracket 151 , and the tension adjustment block 156 is used to adjust the surface tension of the conveyor belt 153 to ensure that the conveyor belt 153 can stably rotate according to the roller member 152 .

[0061] like Figure 3 and Figure 7 As shown, the sorting device 30 includes a robot structure 33 and a suction structure 34. The suction structure 34 is used to suck the objects to be sorted. The robot structure 33 is connected to the suction structure 34 so that when the suction structure 34 sucks the objects to be sorted, the suction structure 34 is driven to drive the objects to be sorted to move. In this way, the suction structure 34 sucks the objects to be sorted to drive the objects to be sorted to move, so that the sorting device 30 can sort the goods to be sorted of different specifications and sizes, thereby improving the versatility of the sorting equipment.

[0062] Specifically, the adsorption method can adapt to more shapes of objects to be sorted. It is only necessary to ensure that the objects to be sorted have a flat surface. In the actual sorting process, regular boxes, soft packages, sheet metal parts, and even envelopes can be adsorbed and sorted.

[0063] Specifically, the structure of the robot structure 33 is relatively conventional and will not be described in detail here.

[0064] like Figure 7 As shown, the adsorption structure 34 includes: a suction cup 341 for adsorbing the object to be sorted, and the suction cup 341 has a connecting protrusion 342; a connecting structure 343, including a plate-like body 3431 and a connecting arm 3432 arranged on the plate-like body 3431, at least two connecting arms 3432, and a connecting space is formed around the at least two connecting arms 3432 and the plate-like body 3431, at least part of the connecting protrusion 342 is located in the connecting space and connected to the connecting arm 3432, and the plate-like body 3431 is used to connect with the driving end of the robot structure 33. In this way, the above arrangement realizes the adsorption function of the adsorption structure 34 through the suction cup 341 on the one hand; on the other hand, the arrangement of the connecting structure 343 and the connecting protrusion 342 enables the adsorption structure 34 to be connected to the driving end of the robot structure 33, so as to ensure that the robot structure 33 can drive the suction cup 341 to move.

[0065] In this embodiment, the connection structure 343 includes a plate-shaped body 3431 and two connection arms 3432 arranged on the plate-shaped body 3431. There are two connection arms 3432 to form a "U"-shaped member.

[0066] Specifically, a communication end is provided on the suction cup member 341 , and the communication end is connected to the vacuum generator through a pipeline to realize the adsorption action of the suction cup member 341 .

[0067] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0068] The conveying device of the sorting equipment is used to convey the objects to be sorted and includes a first conveying structure and a second conveying structure. The first conveying structure is used to convey the objects to be sorted to the second conveying structure. The image acquisition device is used to acquire images of the objects to be sorted located on the conveying device. The sorting device is connected to the image acquisition device to sort the objects to be sorted according to the acquisition results of the image acquisition device. There are at least two sorting devices, and at least one sorting device is used to sort the objects to be sorted on the first conveying structure to the cargo conveyor belt. At least another sorting device has a cyclic sorting state and a regular sorting state. When the sorting device is in the cyclic sorting state, the sorting device sorts the objects to be sorted on the second conveying structure to the first conveying structure to realize cyclic conveyance of the objects to be sorted. When the sorting device is in the regular sorting state, the sorting device sorts the objects to be sorted on the second conveying structure to the cargo conveyor belt. In this way, the sorting device in the present application realizes the automated sorting action of the sorting device through the linkage between the image acquisition device and the sorting device, and realizes the cyclic conveying and multiple sorting of the objects to be sorted through the sorting device in the cyclic sorting state, that is, the objects to be sorted that are not identified and sorted by the sorting device for sorting the objects to be sorted on the first conveying structure can be conveyed by the first conveying structure to the second conveying structure for secondary sorting. If another sorting device also fails to identify and sort the objects to be sorted, or recognizes that the objects to be sorted should be sorted by another sorting device, it can switch to the cyclic sorting state to sort the objects to be sorted to the first conveying structure for re-sorting. The setting of cyclic conveying and multiple sorting of the objects to be sorted makes the sorting device as a whole have an accuracy comparable to or even higher than that of manual sorting. At the same time, the fully automated sorting process also makes the sorting equipment have extremely high sorting efficiency and can reduce human resource consumption and sorting costs, thereby solving the problems of low sorting reliability and high cost of manual material sorting in the prior art.
